Embodiment Construction

[0018] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] like image 3 Shown is the schematic structural view of the jig for five-star dial milling of the present invention; a jig for five-star dial milling of the present invention includes a bottom plate 4 arranged on the workbench and no less than three chucks 7 arranged on the bottom plate 4, the The bottom plate 4 is provided with a guide rail 6 for the sliding of the chuck 7, and the chuck 7 is surrounded by a cavity 3 for accommodating the five-star dial 1, and there are no less than two slots between the chucks 7 for accommodating the five-star dial. The groove 9 of the corner 2 of the plate 1 is provided with a locking device on the chuck 7 .

[0020] In this implementation, the five-star dial 1 is fixed in the cavity 3 by moving the chuck 7, and the gap between the chucks 7 is used to fix the corners 2 of the five-star dial 1, wh...

Abstract

The invention discloses a clamp for five-star pulling plate milling. The clamp comprises a base plate arranged on a workbench and not less than three chucks arranged on the base plate; a guide rail where the chucks slide is arranged on the base plate, a cavity for containing a five-star pulling plate is defined by the chucks, and not less than two grooves for containing corner angles of the five-star pulling plate are formed between the chucks, and a locking device is arranged on each chuck. End face milling and hole boring can be completed on a vertical milling machine through only one clamp for five-star pulling plate milling, original repeated clamping and positioning of a machined content can be completed through one-time clamping and positioning, the clamp cost is reduced, and the production efficiency and the product quality are improved.

Description

technical field [0001] The invention belongs to the technical field of workpiece supports, such as adjustable center frames, and in particular relates to a jig for five-star dial milling. Background technique [0002] The five-star paddle is an important part of the speed change control mechanism, such as figure 1 , figure 2 As shown, the five-star paddle is mainly connected with the shift arm assembly, and its processing process is: drilling→hole drilling-deburring→heat treatment→hole turning→quilting→end face milling→pliers→finished product inspection. During the process, a drilling machine, a CNC lathe, a honing machine and a milling machine are required. A total of 3 sets of special fixtures are required for the drilling machine, CNC lathe, honing machine and milling machine. Since the product needs to be disassembled and installed many times, the positioning error of the product is relatively large. The pass rate of the product is 70-75%. In addition, in the process ...
