Description

Technical Field

[0001] The invention relates to the technical field of shaft sleeve production and processing, and in particular to a fixing fixture used for shaft sleeve production and processing. Background Art

[0002] The sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft. It is a component of the sliding bearing. The main function of the sleeve is to reduce the direct contact between the shaft and the bearing or housing, thereby reducing friction and wear. It also plays the role of fixing the position, bearing sliding, reducing friction and dissipating heat. The production and processing of the sleeve involves multiple steps, including material selection, rough processing, fine processing, heat treatment and surface treatment. In order to ensure that the position of the sleeve is accurate during the processing, so as to ensure that the processed sleeve meets the size and shape required by the design, the present invention proposes a fixing fixture for the production and processing of the sleeve.

[0003] According to the search, Chinese patent literature, announcement number: CN219945294U, discloses an easily adjustable sleeve processing fixture, which retracts the top plate by starting the electric push rod to remove the support for the connecting plate, and then starts the driving mechanism to drive the fastening ring to move toward the clamp block body to squeeze the connecting plate until the movement of the fastening ring encounters resistance when clamping the sleeve, then stops the driving mechanism, and the state of the connecting plate can be limited by the movement of the fastening ring on the connecting plate. The first clamp block or the second clamp block can clamp or loosen the sleeve, and the center point of the clamped sleeve is consistent with the center point of the cylinder and the clamping seat. The second clamp block is clamped into the first clamp block with a rubber strip, and the caliber of the sleeve that the clamp can clamp can be changed by increasing the overall thickness of the clamp block. The number of other clamp blocks installed on the first clamp block can be adjusted according to actual needs, so that smaller sleeves can be clamped. However, in actual use, the device can only clamp and fix shaft sleeves of different models, and cannot drive the shaft sleeve to move so that it is in a suitable processing position, nor can it drive the shaft sleeve to rotate so that it is convenient for processing, which reduces the overall practicality. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a fixing fixture for the production and processing of shaft sleeves, which has the advantages of being able to fix shaft sleeves of different models and sizes, being easy to operate and adjust, and improving processing efficiency, thereby solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a fixing fixture for the production and processing of shaft sleeves, comprising a base, a first motor is fixedly installed on the right side surface of the base, a first limiting slide groove is opened inside the base, a threaded rod and a first sliding block are installed inside the first limiting slide groove, a support is fixedly installed on the top surface of the first sliding block, a disc is fixedly installed on the top surface of the support, a second motor is fixedly installed on the right side surface of the disc, a second limiting slide groove is opened inside the disc, a turntable is installed inside the second limiting slide groove, a rotating shaft is fixedly installed on the right side surface of the turntable, a base is fixedly installed on the left side surface of the turntable, a third limiting slide groove is opened inside the turntable, a bidirectional screw rod and a second sliding block are installed inside the third limiting slide groove, a handle is fixedly installed on the outer end surface of the bidirectional screw rod, a base is fixedly installed on the left side surface of the second sliding block, and an arc clamp is fixedly installed on the left side surface of the base.

[0008] Preferably, the first sliding block is slidably installed inside the first limiting sliding groove.

At the same time, the first limiting slide groove can also effectively limit the moving position of the first slider to prevent excessive movement, etc., thereby improving the overall stability and practicality of the device.

[0010] Preferably, the output shaft of the first motor is fixedly connected to the right end surface of the threaded rod, and the first sliding block is threadedly connected to the outer side surface of the threaded rod.

[0011] Through the above technical solution, when the first motor is started, the output shaft of the first motor can drive the threaded rod to rotate, and the threaded rod can then drive the first slider to slide inside the first limiting slide groove, thereby adjusting the horizontal position of the sleeve, thereby improving the overall practicality of the device.

[0017] Through the above technical solution, when the second slider slides inside the corresponding third limiting groove, the four second sliders can drive the arc-shaped clamping plate to move, so as to clamp and fix the shaft sleeves of different models and sizes.

[0020] Preferably, the number of the base and the number of the arc-shaped clamping plates are both four, and rubber pads are installed on the inner sides of the four arc-shaped clamping plates.

[0021] Through the above technical solution, when the four second sliders drive the base and the arc-shaped clamping plates to move, the four arc-shaped clamping plates can effectively clamp and fix the sleeve, and the rubber pad can increase the friction force in contact with the sleeve, while also protecting the surface of the sleeve to prevent damage to it, thereby improving the overall practicality.

[0022] Compared with the prior art, the present invention provides a fixing fixture for the production and processing of a shaft sleeve, which has the following beneficial effects:

[0023] 1. The present invention places the shaft sleeve approximately at the center position of the base, and then rotates two handles respectively. The handles can drive the bidirectional screw rod to move, and the two bidirectional screw rods can then drive four second sliders to move relative to each other in pairs. The second sliders can drive the base and the arc-shaped clamping plate to move relative to each other. Therefore, the four arc-shaped clamping plates can effectively clamp and fix the shaft sleeve, which not only improves the synchronization rate of the device and enables the shaft sleeve to be accurately installed at the center position of the base, but also the rubber pad can increase the friction of contact with the shaft sleeve, and can also protect the surface of the shaft sleeve to prevent damage to it, thereby improving the overall practicality.

The present invention starts the first motor, and the output shaft of the first motor can drive the threaded rod to rotate, and the threaded rod can then drive the first slider to slide inside the first limiting slide groove, so as to adjust the horizontal position of the sleeve. At the same time, the first limiting slide groove can also effectively limit the moving position of the first slider to prevent excessive movement, etc., thereby improving the overall stability and practicality of the device; starting the second motor, the output shaft of the second motor can drive parts such as the rotating shaft and the turntable to rotate, and then drive the sleeve to rotate, which is convenient for production and processing and improves the overall work efficiency. At the same time, the two limiting rings can effectively limit the position of the turntable to prevent deviation or falling off, etc., thereby improving the overall stability of the device.
