Description

Technical Field

[0001] The utility model relates to the field of cutting equipment, in particular to a lead screw cutting device for linear motor production. Background Technique

[0002] A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. There are various types of linear motors, such as flat type, U-groove type, and tubular type, etc. The advantages of linear motors include a wide range of feed speeds, good speed characteristics, large acceleration, high positioning accuracy, unlimited stroke, simple structure, smooth movement, low noise, etc. These advantages make linear motors widely used in many fields.

[0003] During the production process of linear motors, when the length of the lead screw exceeds the actual requirement, we need to use cutting equipment to cut the lead screw to ensure that its length meets the production requirements. This not only improves production efficiency but also ensures the overall quality and performance of the linear motor.

[0004] When cutting the lead screw, it is necessary to fix the lead screw. When conventional clamps hold the lead screw, the contact surface is generally a plane, while the lead screw is cylindrical. This results in fewer contact points during clamping. When the lead screw is cut, it will be extruded by external forces. Fewer contact points easily lead to instability of the lead screw, causing the lead screw to shift during the cutting process, and the cutting surface is not smooth enough, affecting the processing quality. At the same time, during the cutting process, a large amount of waste chips will be generated, and the cutting waste chips are prone to splashing, which is likely to cause trouble in subsequent cleaning, and the splashing waste chips are likely to accidentally injure the staff, posing a certain safety hazard. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a lead screw cutting device for linear motor production, aiming to improve the problem that when conventional clamps hold the lead screw in the prior art, there are few contact points, and the lead screw is prone to shift during cutting, affecting the processing quality.

The clamp 25, the positioning column 23 and the positioning rod 24 are arranged in two groups, which are symmetrically distributed front and back with the center line of the machine 1. There are multiple groups of chucks 26, which are symmetrically distributed on the two groups of clamps 25 in a staggered manner.

[0033] Reference Figure 1 , Figure 3 , Figure 4 The limiting assembly includes a limiting rod 31, a protrusion is provided on the top of the limiting rod 31 for easy grasping, a limiting groove 301 is provided on the upper surface of the support plate 21, and the inner wall of the positioning plate 22 is elastically connected to the limiting block 33 through a limiting spring 32.

[0034] Reference Figure 1 , Figure 3 , Figure 4 The limit rod 31 passes through and is slidably connected to the upper surface of the positioning plate 22. One end of the limit spring 32 is fixedly connected to the upper surface of the limit block 33. The other end of the limit spring 32 is fixedly connected to the inner wall at the top of the positioning plate 22. When the limit block 33 moves upward, it will squeeze the limit spring 32 to produce a reaction force. The limit block 33 passes through and is slidably connected to the lower surface of the positioning plate 22. The limit block 33 is inserted into the inner wall of the limit groove 301, which can limit the positioning plate 22. The left surface of the limit block 33 is set to an inclined surface. By squeezing the inclined surface of the limit block 33, the limit block 33 will move upward and disengage from the limit groove 301 to release the limit on the positioning plate 22. The lower surface of the limit rod 31 is fixedly connected to the upper surface of the limit block 33.

[0035] Reference Figure 1 - Figure 3, the lower surface of the support plate 21 is fixedly connected to the upper surface of the machine table 1. Two sets of horizontal grooves 201 and inclined grooves 202 are provided. The two sets of horizontal grooves 201 and inclined grooves 202 are symmetrically distributed front and back with respect to the center line of the support plate 21, and the positions of the two positioning rods 24 can be controlled simultaneously.

[0036] Refer to Figure 1 - Figure 3 , the positioning rod 24 is slidably connected to the inner wall of the horizontal groove 201, the positioning rod 24 is slidably connected to the inner wall of the inclined groove 202. When the positioning plate 22 moves, it will drive the inclined groove 202 to move. The moving inclined groove 202 will squeeze the positioning rod 24, and the positioning rod 24 will move back and forth along the track of the horizontal groove 201. The positioning column 23 penetrates and is slidably connected to the front surface of the machine table 1, and the chuck 26 is set to be arc-shaped.

[0037] Refer to Figure 1 - Figure 3 , the cutting assembly includes a drawer 41. A handle is provided on the front surface of the drawer 41. By grasping the handle, the drawer 41 can be pulled out. An electric telescopic rod 42 is provided on the upper surface of the support plate 21. The upper surface of the electric telescopic rod 42 is fixedly connected to a top plate 43. The electric telescopic rod 42 can drive the top plate 43 to move longitudinally. A cutting machine 44 is provided on the lower surface of the top plate 43. The cutting machine 44 can cut the lead screw. The electric telescopic rod 42 and the cutting machine 44 are prior arts and can be realized by those skilled in the art. Since they are prior arts, they will not be described in detail in this case.

[0038] Refer to Figure 1 - Figure 3 , the drawer 41 penetrates and slides on the front surface of the machine table 1, and the cutting machine 44 is aligned with the through groove.

[0039] Working principle: First, the lead screw to be truncated is placed into the machine table 1 from the circular groove. Then, move the positioning plate 22 to the left to drive the limit block 33 to move to the left. When the limit block 33 moves to the left, the inclined surface will be squeezed. The limit block 33 will move upward to squeeze the limit spring 32 to generate a reaction force, and it will also disengage from the limit groove 301 to release the limit on the positioning plate 22, enabling the positioning plate 22 to move to the left. The positioning plate 22 moving to the left will drive the inclined groove 202 to move to the left. The inclined groove 202 moving to the left will squeeze the positioning rod 24. When the positioning rod 24 is squeezed, it will move towards the center of the support plate 21 along the track of the horizontal groove 201. The moving positioning rod 24 will drive the positioning column 23, the clamping plate 25 and the chuck 26 to move synchronously. The moving chuck 26 will clamp and fix the lead screw. After the clamping is completed, the reaction force of the limit spring 32 will push the limit block 33 to be inserted into the limit groove 301 to limit the positioning plate 22 and ensure the stability of the device.

[0040] After the screw is clamped, the electric telescopic rod 42 and the cutting machine 44 are started to start cutting the screw. The waste generated during the cutting process will be blocked by the machine table 1 and the support plate 21, and finally fall into the drawer 41. After the cutting is completed, the electric telescopic rod 42 and the cutting machine 44 are closed first, and then the limit rod 31 is pulled upward to drive the limit block 33 to move upward to disengage from the limit groove 301 to release the limit on the positioning plate 22, and then the positioning plate 22 is moved to the right to drive the transverse groove 201 to move to the right to squeeze the positioning rod 24. At this time, the positioning rod 24 is squeezed and moves along the trajectory of the transverse groove 201 toward the edge of the support plate 21. The moving positioning rod 24 will drive the positioning column 23, the clamping plate 25 and the chuck 26 to synchronously open and contact the clamping of the screw, and then the screw is removed, and the drawer 41 is pulled out to clean up the waste.
