Description

Technical Field

[0001] The utility model relates to the technical field of clamping fixtures for motor casings, in particular to a clamping fixture for a motor casing. Background Art

[0002] A fixture refers to a device used to fix a processing object during the mechanical manufacturing process, so that it occupies the correct position to receive construction or inspection, also known as a chuck. Generally speaking, any device used to quickly, conveniently and safely install a workpiece in any process of the technological process can be called a fixture.

[0003] A motor casing is a casing used to cover the outside of a motor rotor and stator to protect the internal components of the motor. The maximum clamping span of existing motor casing fixtures is usually fixed and cannot adapt to motor casings of different sizes, so the practicability needs to be improved. Therefore, a clamping fixture for a motor casing is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A clamping fixture for a motor casing includes a base. A rotating assembly is arranged at the top end of the base. The rotating assembly includes a turntable. A pressing assembly is installed at the top end of the front surface of the turntable. A clamping assembly is installed at the bottom end of the front surface of the turntable. The clamping assembly includes a bottom plate connected and fixed to the turntable. Two adjusting components are symmetrically installed at the top of the bottom plate. The adjusting component includes a guide block. The guide block is embedded in the bottom plate through a guide groove. A positioning column is connected to the top end of the guide block. A sleeve is sleeved outside the positioning column. The guide block is threadedly sleeved on the surface of an adjusting screw. The left side of the adjusting screw passes through a through hole inside the bottom plate. The inner side of the top end of the sleeve is connected with a clamping plate.

[0007] Preferably, a support spring is connected to the bottom end of the sleeve. The outer side of the clamping plate is in an L-shaped structure. A groove is opened on the outer side of the clamping plate. The sleeve can be supported by the resilience of the support spring, so that the clamping plate can maintain the adapted height under normal conditions.

[0008] Preferably, an adapter plate is connected between adjacent two sleeves. A threaded rotating rod is inserted through a threaded hole at the center position of the adapter plate. The bottom end of the threaded rotating rod is rotatably docked with a docking plate. Both ends of the docking plate are connected and fixed to the positioning column. The movement of the sleeve can drive the clamping plate to press and fix the bottom end of the motor casing, ensuring the stability of the installation of the motor casing.

[0009] Preferably, the pressing component includes a suspension plate. A groove is formed in the front of the top end of the suspension plate, and a placement plate is placed on the surface of the groove. A threaded rotating shaft is inserted through a threaded hole at the center of the top end of the placement plate, and a pressing block is rotatably connected to the bottom end of the threaded rotating shaft. A trapezoidal groove is formed at the bottom end of the pressing block. By pushing the pressing block downward through the threaded rotating shaft, the pressing block is controlled to be buckled on the surface of the motor housing, ensuring the stability of the motor housing during clamping.

[0010] Preferably, two threaded columns are symmetrically connected to the left and right sides of the top end of the groove of the suspension plate, and the threaded columns pass through the placement plate through through holes and are threadedly sleeved with nuts. The nuts can move on the surface of the threaded columns, facilitating the staff to disassemble and assemble the placement plate.

[0011] Preferably, a vertical frame is connected to the top end of the base, and a placement seat is connected to the back of the top end of the vertical frame. A driving motor is installed on the surface of the placement seat, and the output end of the driving motor is connected and fixed to a turntable through a through hole penetrating the vertical frame. The driving motor can be supported by the placement seat, ensuring the stability of the suspension installation of the driving motor.

[0012] Preferably, the guide block has a rectangular structure, and the inner diameter of the guide groove of the bottom plate is adapted to the guide block. The guide block can be guided and limited through the guide groove of the bottom plate, ensuring the stability of the guide block during movement.

[0013] The present utility model at least has the following beneficial effects:

[0014] 1. By setting the pressing component and the clamping component, the blocking of small rolling stones is realized. Compared with the traditional structure, in this device, the threaded rotating rod is rotated to control the connecting plate to move downward on the surface of the threaded rotating rod. The movement of the connecting plate can control the adjusting component to fix the base of the motor housing. At the same time, the threaded rotating shaft can move downward in the threaded hole of the placement plate to push the pressing block, so that the pressing block can be buckled on the surface of the motor housing, ensuring the stability of the motor housing during clamping, adapting to motor housings of different sizes, and improving the practicability of the device.

[0015] 2. By setting the adjusting component, the distance between two opposite guide blocks is adjusted. In this device, the adjusting screw rod is rotated to control the relative movement of the two guide blocks, so that the guide blocks drive the positioning columns to move. The movement of the positioning columns can control the movement of the clamping plate through the sleeve, thereby reducing the distance between the two clamping plates. The clamping plate can provide two fixing methods: side clamping and downward pressing, thereby improving the diversity of the fixing of the motor housing. Description of the Drawings
