[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] Example 1

[0027] like Figure 1 - Figure 4As shown, the present invention proposes a motor shaft milling fixture, comprising: a worktable 1, a clamping assembly 2, a clamping plate 3, a receiver 4, an auxiliary assembly 5, and a collection box 6; the worktable 1 has an opening and guide grooves on both sides; the clamping assembly 2 is connected to one end of the worktable 1; the clamping assembly 2 includes a clamping member, the clamping member is connected to a mounting base 208, the mounting base 208 is connected to a laser emitter 209 and a receiver 4; the clamping plate 3 is connected to the other end of the worktable 1; the clamping plate 3 is used to cooperate with the clamping assembly 2 to clamp the motor shaft. The machine shaft is a workpiece; the clamping plate 3 is provided with a groove, and the groove is connected to the measuring plate; the auxiliary component 5 is connected to the worktable 1; the collection box 6 is connected to the bottom of the worktable 1; the collection box 6 is connected to the connecting seat 601, the connecting seat 601 is connected to the fan 602, the fan 602 is connected to the air duct 603, the air duct 603 passes through the collection box 6 and connects to the filter plate 604, the filter plate 604 is provided with filter holes, the two sides inside the collection box 6 are respectively connected to the inclined plates 605 and the two sides outside are respectively connected to the mounting plates 606, which are used to connect to both ends of the worktable 1 and are detachable. The mounting plate 606 and the worktable 1 are connected at both ends by flange bolts, which is simple to operate and easy to use. Through the cooperation of the air duct 603 and the fan 602, debris is sucked into the collection box 6, preventing debris from affecting the secondary operation of the fixture and improving the efficiency of motor shaft machining. A laser emitter 209 and a receiver 4 are set up. The laser emitter 209 projects a visible red laser onto the measuring plate through its lens, and the receiver 4 receives the laser reflected from the measuring plate. The laser is then received by the internal CCD linear camera through the lens of the receiver 4. Depending on the distance, the CCD linear camera can "see" this light spot at different angles. Based on this angle, the distance between the laser and the camera is known, allowing for the determination of the distance between the clamping rod 207 and the clamping plate 3, facilitating the determination of the motor shaft length. This makes the fixture structure convenient for measuring the motor shaft length, improving the functionality of the motor shaft milling fixture and expanding its application range.

[0028] To further explain, the collection box 6 is connected to the opening and is used to collect debris generated during the machining of the motor shaft workpiece. The filter plate 604 is connected inside the collection box 6. The distance between the two inclined plates 605 forms an inlet, which is connected to the collection box 6. The inclined ends of the two inclined plates 605 face inwards towards the collection box 6, which facilitates the automatic falling of debris into the collection box 6 and improves the utilization of the collection box 6.

[0029] Further explanation: Auxiliary component 5 includes two upright plates 501 connected to both sides of the worktable 1. Each upright plate 501 is connected to an electric telescopic rod 502. The drive end of the electric telescopic rod 502 passes through the upright plate 501 and connects to a block 503. The block 503 is connected to a clamping plate 504. The distance between the two clamping plates 504 is adjustable to form a clamping chamber, which assists the clamping component 2 and clamping plate 3 in clamping the motor shaft. Using auxiliary component 5 to clamp the motor shaft improves clamping stability and expands the applicability of milling groove clamping for the motor shaft.

[0030] Example 2

[0031] like Figure 2 As shown, the present invention proposes a motor shaft milling fixture. Based on the above embodiments, this embodiment also details the specific components of the clamping parts and their mating methods.

[0032] Further explanation: The clamping component includes a support plate 201 connected to the worktable 1. Clamping plates 202 are connected to the lower ends of both ends of the support plate 201, and a cylinder 203 is connected to one side. A moving rod 204 is connected to the driving end of the cylinder 203. The moving rod 204 passes through the support plate 201 and connects to a mounting block 205. A connecting block 206 is connected to the mounting block 205, and a clamping rod 207 is also connected to it. Both the mounting block 205 and the connecting block 206 have through holes with threads on their inner walls. Bolts are threaded through and fixed to these holes, allowing for the installation of the mounting block 205 and the connecting block 206. This facilitates the operation and disassembly of the clamping assembly 2, improving its practicality.

[0033] To further explain, the mounting block 205 and the connecting block 206 are detachably connected. Guide rods 210 are connected to both sides of the connecting block 206, and one end of the clamping rod 207 is connected to the mounting base 208. The guide rods 210 are movably connected within the guide groove, and one end of the guide groove is fixedly connected to a clamping plate 202 for reinforcing the installation of the support plate 201. The guide rods 210 move synchronously with the connecting block 206 and along the guide groove, which facilitates smoother movement of the clamping rod 207, improves the clamping stability of the motor shaft, and enhances the machining quality of the motor shaft.

[0034] The working principle of this utility model is as follows: When using the motor shaft milling fixture, the hollow end of the motor shaft passes through the clamping rod 207 and is supported on the clamping rod 207. The cylinder 203 is activated, and its driving end causes the moving rod 204 to move. The moving rod 204 drives the mounting block 205 and the connecting block 206. The connecting block 206 drives the clamping rod 207 towards the clamping plate 3. The clamping plate 3, in conjunction with the clamping rod 207, clamps the motor shaft. A measuring plate, laser emitter 209, and receiver 4 are used to measure the distance between the clamping rod 207 and the clamping plate 3, and to measure the length of the motor shaft. This ensures that the lengths of motor shafts processed in the same batch are the same. After measurement, the measuring equipment is turned off. Activating the electric telescopic rod 502 causes the block 503 to move, which in turn moves the clamping plate 504 to the periphery of the motor shaft. This clamping plate 504 clamps the motor shaft, allowing the operator to easily process the shaft. The debris generated during processing is drawn into the collection box 6 by activating the fan 602, which, through the duct 603 and filter holes. When the debris needs to be cleaned, the mounting plate 606 is disconnected from the worktable 1, allowing for easy cleaning. This simple operation improves the working efficiency of the motor shaft milling fixture.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
