Description

Technical Field

[0001] The invention relates to the technical field of motor processing fixtures, in particular to a motor shaft keyway processing fixture. Background Art

[0002] When machining the keyway on the motor shaft, the operation is usually completed on a turning machine. At present, the motor shaft is basically clamped and fixed using the ejector on the lathe. Since the ejector assembly on each lathe is fixed, the clamping of motor shafts of different models is limited, and the applicability is not strong. Moreover, when the fixed ejector assembly is damaged, it is troublesome to repair, and the entire lathe needs to be stopped for processing, which affects production efficiency. Summary of the invention

[0003] In response to the above problems, the present invention provides a motor shaft keyway processing fixture, which is a separate assembly component and can be installed on different lathes according to usage requirements. Even if it is damaged, it is easy to repair and replace without affecting production efficiency.

[0004] The technical solution of the present invention is as follows:

[0005] A motor shaft keyway processing fixture, the processing fixture consists of two parts arranged in mirror symmetry, each part includes a mounting plate detachably connected to a lathe, a support plate is longitudinally provided on the mounting plate, a clamping arm is passed through the support plate, a driving mechanism for driving the clamping arm to move linearly and reciprocatingly is provided on the mounting plate, a clamping plate is provided at the front end of the clamping arm, the clamping plate is a longitudinally arranged circular arc clamping plate, and the arc center angle of the clamping plate is 30°-75°.

[0006] In a further technical solution, the clamping plate is formed by a plurality of arc segments hinged in sequence, and two adjacent arc segments are connected by a spring.

[0007] In a further technical solution, a clamping strip for engaging with a mounting slot reserved on a lathe is provided at the bottom of the mounting plate.

[0008] In a further technical solution, the driving mechanism is a driving cylinder.

[0009] In a further technical solution, the driving cylinders are two groups of synchronous driving cylinders arranged on both sides of the clamping arm.

[0010] In a further technical solution, bolt holes are provided on the mounting plate.

[0011] The beneficial effects of the present invention are:

[0012] The processing fixture of the present invention is specially used for the processing of motor shafts. It is a separate assembly component and can be installed on different lathes according to usage requirements. Even if it is damaged, it is easy to repair and replace without affecting production efficiency. Moreover, the splint is composed of a multi-section structure hinged together and can be stretched by a spring, which can meet the clamping requirements of motor shafts of different sizes.
