Adopt after above structure, the utility model compared with prior art has the following advantages: ensure that by five supporting seats workpiece can not swing up and down, it is mainly the first pressure head, the second pressure head and the 3rd pressure head are pressed in workpiece surface, and the 3rd supporting seat and the 5th supporting seat are used for withstanding on workpiece lower surface, utilize the first limited support point, the second limited support point and the 3rd limited support point can not rotate workpiece, like this workpiece is effectively located, then bridge plate being arranged on to the hole that numerically controlled lathe just can effects on surface has processed, only need clamped one time location can not cause dimensional discrepancy, workpiece size stability improves simultaneously stablizing of in the time of follow-up assembling properties of product greatly.
As preferably, described positioning component be two groups and two groups symmetrical, the convenient left and right arms of simultaneously processing BMW Triangular Arm, efficiency is high.
As preferably, described bridge plate is provided with at least two suspension ring, convenient bridge plate is sling to be arranged on numerically controlled lathe.
As preferably, described suspension ring are four orthogonal arrangements, and suspension bridge plate is steady.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in the figure, the utility model provides a kind of BMW Triangular Arm frock, it comprises bridge plate 1, workpiece 2 and at least one group of positioning component, described workpiece 2 comprises first jiao 9, second jiao 10 and triangle 11, described second jiao 10 is provided with the first hole 14, described triangle 11 is provided with the second hole 17, described positioning component refers to that described bridge plate 1 is provided with the first supporting seat 3, the second supporting seat 4, the 3rd supporting seat 5, four-supporting 6 and the 5th supporting seat 7, the first described supporting seat 3 is provided with for pushing down first jiao 9 and the first pressure head 13 of being connected with oil cylinder, the second described supporting seat 4 is provided with for pushing down second jiao 10 and the second pressure head 16 of being connected with oil cylinder, the 3rd described supporting seat 5 is provided with the support bar 8 for supporting the first hole 14 and being connected with oil cylinder, described four-supporting 6 is provided with the 3rd pressure head 15 for pushing down 17 one end, nearly the second hole and being connected with oil cylinder, the 5th described supporting seat 7 is provided with for supporting workpiece 2 centers and the spacing steel ball head 18 of activity that is connected with oil cylinder, the outer surface of 17 one end, nearly the second hole of described workpiece 2 is provided with the first limited support point 19 towards first jiao 9, the outer surface of 17 one end, nearly the second hole of described workpiece 2 is provided with the second limited support point 20 towards second jiao 10, the outer surface of 17 one end, nearly the second hole of described workpiece 2 is provided with the 3rd limited support point 12 towards first jiao 10, the utility model has the advantages that by five supporting seats and ensure that workpiece can not swing up and down, it is mainly the first pressure head 13, the second pressure head 16 and the 3rd pressure head 15 are pressed in workpiece 2 upper surfaces, and the 3rd supporting seat 5 and the 5th supporting seat 7 are for withstanding on workpiece 2 lower surfaces, utilize the first limited support point 19, the second limited support point 20 and the 3rd limited support point 12 can not rotate workpiece 2, like this workpiece is effectively located, then bridge plate 1 being arranged on to the hole that numerically controlled lathe just can effects on surface has processed, only need clamped one time location can not cause dimensional discrepancy, workpiece size stability improves simultaneously stablizing of in the time of follow-up assembling properties of product greatly.
Described positioning component be two groups and two groups symmetrical, the convenient left and right arms of simultaneously processing BMW Triangular Arm, efficiency is high.
Described bridge plate 1 is provided with at least two suspension ring 21, conveniently bridge plate 1 is sling to be arranged on numerically controlled lathe.
Described suspension ring 21 are four orthogonal arrangements, and suspension bridge plate 1 is steady.
Specifically, BMW Triangular Arm is carried out to contraposition, as long as workpiece 2 does not swing up and down and rotates just explanation and located, the utility model ensures that by five supporting seats workpiece can not swing up and down, it is mainly the first pressure head 13, the second pressure head 16 and the 3rd pressure head 15 are pressed in workpiece 2 upper surfaces, and the 3rd supporting seat 5 and the 5th supporting seat 7 are for withstanding on workpiece 2 lower surfaces, utilize the first limited support point 19, the second limited support point 20 and the 3rd limited support point 12 can not rotate workpiece 2, like this workpiece is effectively located, then bridge plate 1 being arranged on to the hole that numerically controlled lathe just can effects on surface has processed, only need clamped one time location can not cause dimensional discrepancy, workpiece size stability improves simultaneously stablizing of in the time of follow-up assembling properties of product greatly.
Be described with regard to the utility model preferred embodiment above, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change, and all various variations of doing in the protection domain of the utility model demand for independence are all in protection domain of the present utility model.
