Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, in particular to a clamp for processing a needle cylinder of a knitting machine. Background Art

[0002] In the motor manufacturing industry, the motor end cover is an important part of the motor, and its processing quality directly affects the overall performance and life of the motor. However, in the traditional motor end cover processing process, the burr trimming process often faces many challenges.

[0003] First, the motor end caps have different shapes and sizes, and motor end caps of different specifications and models require different fixtures to fix them, which leads to frequent fixture replacement, increasing production costs and processing time. At the same time, due to unreasonable fixture design or improper operation, it is often difficult to ensure the stability of the motor end cap during the trimming process, and the workpiece is prone to movement or offset, thus affecting the accuracy and quality of the trimming.

[0004] Secondly, most traditional methods of trimming burrs are manual or semi-automatic, which is not only inefficient but also difficult to ensure uniformity and consistency of trimming. In addition, manual operation is easily affected by the worker's skill level and fatigue, further increasing processing errors and defective product rates. Utility Model Content

This innovative design ensures that the clamps on the two movable blocks can clamp the needle cylinder workpiece on the base with uniform and controllable force. The contact surface between the clamp and the needle cylinder is finely polished to form an arc surface that perfectly matches the surface of the workpiece, thereby achieving a close fit between the clamp and the workpiece, effectively avoiding sliding or loosening during the clamping process.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0016] like Figure 1 As shown, the embodiment of the utility model provides a clamp for processing needle cylinders of knitting machines, including a base 1 and a servo motor 3. Two fixed plates 2 are fixedly connected to the top of the base 1. The servo motor 3 is fixedly connected to the side wall of one of the fixed plates 2 away from the other fixed plate 2. Two movable rods 6 are arranged between the two fixed plates 2. Both ends of the movable rod 6 are fixedly connected to second connecting rods 5. The two second connecting rods 5 and the movable rod 6 form a U-shape. One end of the two second connecting rods 5 away from the movable rod 6 is fixedly connected to a first connecting rod 4. One of the first connecting rods 4 is connected to the driving end of the servo motor 3. Fixed connection, one end of the first connecting rod 4 close to the servo motor 3 is rotatably connected to one of the fixed plates 2, and the other end of the first connecting rod 4 away from the movable rod 6 passes through the other fixed plate 2, and the other end of the first connecting rod 4 away from the movable rod 6 is fixedly connected with a transmission wheel 11, and the outer surfaces of the two transmission wheels 11 are both sleeved with transmission belts 12. The top of the base 1 is symmetrically slidably connected with a movable block 8, and the side wall of the movable block 8 is penetrated by a limiting groove 7. The movable rod 6 is slidably connected to the inside of the limiting groove 7, and the side wall of the movable block 8 away from the movable rod 6 is fixedly connected with a clamping plate 9.

[0017] The two clamps 9 are symmetrically arranged to ensure the balance and stability of the clamp when clamping the syringe workpiece. The outer surface of the clamp 9 away from the movable block 8 is designed as a curved surface, which enables the clamp 9 to fit closely with the outer surface of the syringe workpiece, avoiding sliding or loosening during the clamping process, thereby significantly improving the clamping effect.

[0018] The top of the clamping plate 9 is fixedly connected with an arc plate 10, and the center axis of the arc plate 10 is in the same straight line as the center axis of the arc surface of the clamping plate 9. This design allows the workpiece to be fixed by fitting the arc plate 10 to the inner wall of the workpiece when the outer surface of the syringe needs to be processed, providing a good operating interface and convenient processing conditions for external processing equipment. The close connection between the arc plate 10 and the clamping plate 9 also ensures the stability and accuracy of the syringe during the processing.

[0019] The transmission belt 12 is located on one side of the two fixed plates 2. This design makes the transmission structure more compact and efficient. The transmission action of the transmission belt 12 can ensure the synchronous movement of the two movable rods 6, thereby achieving uniform clamping of the syringe workpiece by the two clamping plates 9. The efficient transmission mechanism also improves the response speed and clamping efficiency of the clamp.

[0020] Working principle: When using the clamp for knitting machine needle cylinder processing, the operator places the needle cylinder workpiece to be processed between the two clamping plates 9, and the servo motor 3 can drive one of the first connecting rods 4 to rotate, and the first connecting rod 4 drives the connected movable rod 6 to rotate in a circle, and the movable rod 6 drives the other connected first connecting rod 4 to rotate, and the first connecting rod 4, under the joint action of the transmission wheel 11 and the transmission belt 12, makes the other movable rod 6 and the movable rod 6 rotate synchronously, and the movable rod 6 is clamped in the limit groove 7 on the movable block 8, so that the movable rod 6 can drive the movable block 8 to move linearly along the top of the base 1, so that the clamps 9 on the two movable blocks 8 move toward each other, so the two clamps 9 can clamp the two sides of the workpiece between the two clamps 9, and the contact surface between the clamps 9 and the syringe is finely polished to form an arc surface that perfectly matches the surface of the workpiece, thereby achieving a close fit between the clamps 9 and the workpiece, effectively avoiding sliding or loosening during the clamping process. When the workpiece is processed, the clamps 9 are reset by the servo motor 3 to remove the workpiece from the fixed state, which is convenient for the operator to remove the workpiece on the base 1. Moreover, when it is necessary to process the outer circle of the syringe, the servo motor 3 can drive the two clamps 9 to have a minimum spacing, which is convenient for the operator to insert the workpiece into the two arc plates 10, and then the servo motor 3 drives the two arc plates 10 to move apart, so that the two arc plates 10 fit the inner wall of the workpiece, thereby firmly and stably fixing the workpiece on the base 1.

[0021] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
