[0002] In the field of motor manufacturing, motor shafts are key transmission components, and their machining accuracy and production efficiency directly affect the overall performance and quality of the motor. Cutting, as a crucial process in motor shaft production, mainly involves cutting raw materials (such as round steel, shaft materials, etc.) to a fixed length or trimming already formed shafts. Traditional cutting methods often employ manual or semi-automatic equipment, such as ordinary saws, shearing machines, or hand cutting tools, which suffer from low efficiency, high labor intensity, low cutting accuracy, and poor operational safety.

[0003] To address these issues, we provide a cutting device for producing motor shafts. Utility Model Content

The rotating assembly includes a transmission seat fixed to the edge of the worktable, a clamp fixed to the front of the transmission seat, a transmission belt for driving the rotation of the transmission seat, and a rotating motor. The motor shaft passes through the clamp and the transmission seat, and the jaws of the clamp hold and fix the motor shaft around its periphery.

[0005] The present invention is further configured such that a positioning fixture for fixing the motor shaft is installed at the front of the worktable. The positioning fixture includes an inner support seat fixed to the front of the upper side of the worktable and an outer support seat located outside the edge of the worktable. Both the inner support seat and the outer support seat are provided with balls for assisting the rotation of the motor shaft in their recessed surfaces.

[0006] The present invention is further configured such that the positioning fixture includes a mounting base fixed to the front edge of the workbench, a pneumatic rod fixed at an incline to the upper part of the mounting base, and a positioning turntable fixed to the end of the pneumatic rod. The positioning turntable and the inner support base form a positioning system for the motor shaft.

[0007] The present invention is further configured such that a notch for cylinder installation is provided at the middle position of the rear end of the worktable, and the telescopic end of the cylinder cooperates with the transmission frame through a connecting rod.

[0008] The present invention is further configured such that a cover is fixed to the front edge of the workbench, the rotary motor is fixed to the outside of the cover, the transmission belt is located inside the cover, and the rotary motor cooperates with the transmission seat through the transmission belt.

Example

[0018] Please see Figure 1-4 This utility model relates to a cutting device for producing motor shafts, comprising a worktable 100, a cutting assembly 200 and a rotating assembly 400 mounted on the worktable 100. The cutting assembly 200 includes a transmission frame 203 rotatably mounted above the worktable 100 via a bearing seat 206, a drive motor 204 mounted at the tail of the transmission frame 203, a cutting tool 205 mounted at the front of the transmission frame 203, and a cylinder 201 for adjusting the rotation of the transmission frame 203 relative to the bearing seat 206. The rotating assembly 400 includes a transmission seat 402 fixed to the side of the worktable 100, a chuck 401 fixed to the front of the transmission seat 402, a transmission belt 403 for driving the rotation of the transmission seat 402, and a rotating motor 405. The motor shaft passes through the chuck 401 and the transmission seat 402, and the grippers of the chuck 401 clamp and fix the motor shaft to the periphery.

[0019] Specifically, a positioning fixture 300 for fixing the motor shaft is installed at the front of the worktable 100. The positioning fixture 300 includes an inner support seat 301 fixed to the front of the upper side of the worktable 100 and an outer support seat 305 located outside the edge of the worktable 100. Both the inner support seat 301 and the outer support seat 305 are provided with balls for assisting the rotation of the motor shaft in their recessed surfaces. The positioning fixture 300 also includes a mounting seat 302 fixed to the front edge of the worktable 100, a pneumatic rod 303 inclinedly fixed to the upper part of the mounting seat 302, and a positioning turntable 304 fixed to the end of the pneumatic rod 303. The positioning turntable 304 and the inner support seat 301 form a positioning system for the motor shaft.

[0020] Furthermore, a notch for mounting a cylinder 201 is provided at the middle of the rear end of the worktable 100. The telescopic end of the cylinder 201 is connected to the transmission frame 203 via a connecting rod 202. A cover 404 is fixed to the front edge of the worktable 100. The rotary motor 405 is fixed to the outside of the cover 404. The transmission belt 403 is located inside the cover 404. The rotary motor 405 is connected to the transmission seat 402 via the transmission belt 403. A circular hole is provided at the end of the cover 404 for the motor shaft to pass through and be mounted. The circular hole is coaxially arranged with the transmission seat 402 and the clamp 401.

[0021] In addition, the cutting tool 205 is located directly above the outside of the chuck 401, and the cutting tool 205 is equipped with a protective cover.

[0022] In the cutting equipment for producing motor shafts provided in this embodiment, the worktable 100 serves as an overall support base, on which a cutting assembly 200 for cutting the motor shaft and a rotating assembly 400 for driving the motor shaft 204 to rotate are installed. Specifically, the cutting assembly 200 includes a transmission frame 203 rotatably mounted on the worktable via a bearing seat 206. A cutting tool 205 is mounted at the front of the transmission frame 203, and a drive motor 204 is connected to the rear. A cylinder 201 drives the entire transmission frame 203 to rotate via a connecting rod 202, thereby controlling the cutting tool 205 to perform a cutting operation on the motor shaft. The rotating assembly 400 consists of a transmission seat 402 fixed to the edge of the worktable, a clamp 401, a transmission belt 403, and a rotating motor 405. The motor shaft is clamped inside the clamp 401 and rotates to cut the motor shaft. The motor 405 drives the transmission seat 402 to rotate via the transmission belt 403, thereby causing the motor shaft to rotate synchronously, which facilitates continuous processing. In addition, the front of the worktable is provided with a positioning fixture 300, including an inner support seat 301 and an outer support seat 305. The ball bearings in the recessed surfaces of the two can assist the motor shaft to rotate smoothly and improve the processing accuracy. At the same time, the positioning fixture 300 also includes a mounting seat 302, a pneumatic rod 303 and a positioning turntable 304. The positioning turntable 304 and the inner support seat 301 together constitute the positioning system of the motor shaft, ensuring that the shaft maintains a stable posture during the cutting process.

[0023] The specific operating steps of the cutting equipment for producing motor shafts are as follows: First, insert one end of the motor shaft into the transmission seat 402 and the clamping plate 401, and place the motor shaft to be processed on the positioning fixture 300 at the front end of the worktable. The motor shaft is initially supported by the balls of the inner support seat 301 and the outer support seat 305, and the positioning turntable 304 is pushed by the air rod 303 to make the positioning turntable 304 cooperate with the inner support seat 301 to complete the precise positioning and clamping posture adjustment of the motor shaft; then, the clamping jaws of the clamping plate 401 firmly clamp the shaft to ensure that the shaft is stable and does not deviate during rotation; start After the rotating motor 405 is activated, the power is transmitted to the transmission seat 402 through the transmission belt 403, which drives the chuck 401 and the motor shaft to rotate synchronously, thereby realizing the continuous rotation of the shaft and facilitating the cutting operation. At the same time, the cutting assembly 200 starts to work, and the drive motor 204 drives the cutting tool 205 to work. Under the action of the cylinder 201 pushing the transmission frame 203 to make a slight angle adjustment through the connecting rod 202, the cutting tool 205 installed at the front of it is moved down and aligned with the predetermined position of the motor shaft directly above the outside of the chuck 401, so as to achieve precise control of the cutting depth and complete the precise cutting of the motor shaft.
