Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of connector processing, in particular to a clamping head for welding the end of a twist pin. Background Technique
[0002] The commonly used pin on the connector is in a twist shape. This kind of pin has high structural strength and strong electrical conductivity. When processing the twist pin, it is first cut into several small sections by cutting, and then the end is welded by laser welding to prevent the twist pin from being scattered during use. And during the welding operation, the twist pin is clamped by a clamping jaw, and then the clamping jaw rotates to make the twist pin face the laser head, and then the welding operation is carried out by the laser head. However, during the welding operation, there is always a problem that some copper wires are not welded, which affects the quality of the twist pin. And during the clamping, it is driven by a cylinder for clamping. However, the failure rate of the cylinder is relatively high, which has a certain impact on the production efficiency. Content of the Utility Model
[0003] The utility model provides a clamping head for welding the end of a twist pin to solve the above-mentioned deficiencies of the prior art, solve the problem of poor welding effect of the twist pin, and has strong practicability.
[0004] In order to achieve the purpose of the utility model, the following technology is proposed:
[0005] A clamping head for welding the end of a twist drill bit includes a rectangular plate. A pair of guiding holes are respectively opened at both ends of the rectangular plate. The length direction of the guiding holes is parallel to the length direction of the rectangular plate. Connecting screws are inserted through the guiding holes. Lower moving plates are respectively provided at the lower ends of the connecting screws at the same end. The lower moving plates are located on the lower side of the rectangular plate. A moving plate is provided on the lower moving plate. A movable long hole is opened on the moving plate. The upper end of the movable long hole extends inwardly and obliquely. A pressing rod is inserted through the movable long hole. A concave moving seat is provided on the pressing rod. A connecting arm is provided at the lower end of the moving plate. An installation lower plate is installed at the lower end of the connecting arm. A rotating seat is installed on the inner side of the installation lower plate. A clamping wheel is rotatably provided at the inner end of the rotating seat. A servo motor is installed on the rectangular plate. A lead screw is connected to the output shaft of the servo motor. A moving nut sleeve is provided on the lead screw. A movable block is provided at the lower end of the moving nut sleeve. A moving rotating seat is installed at the lower end of the movable block. A driving wheel is rotatably provided at the inner end of the moving rotating seat. One end of the driving wheel is connected with a driven bevel gear. A driving bevel gear is meshed with the driven bevel gear. A driving motor is connected to the driving bevel gear. The driving motor is installed on the movable block through a mounting plate. Through the provided driving motor, it can drive the driving wheel to rotate, so as to drive the twist drill bit to rotate through the driving wheel, and perform all-round welding operation on the end of the twist drill bit through a laser head. When clamping the twist drill bit, the servo motor drives the lead screw to make the driving wheel and the clamping wheel clamp the twist drill bit. This driving method has a lower failure rate. And when the driving wheel approaches the twist drill bit, it will make the clamping wheel approach the twist drill bit at the same time and perform the clamping operation.
[0006] Further, when clamping, the clamping wheels and the driving wheels are distributed in a circumferential array. In this way, the clamping effect can be improved.
[0007] Further, anti-slip patterns are provided on the outer circumferences of the clamping wheels and the driving wheels to ensure stable rotation of the twist drill bit.
[0008] The advantages of the above technical solution are as follows:
[0009] The utility model reduces the failure rate when clamping the twist drill bit and improves the welding effect. Brief Description of the Drawings
[0010] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings.
[0011] Figure 1 Shows the three-dimensional structure of one of the embodiments Figure 1 .
[0012] Figure 2 Shows the three-dimensional structure of one of the embodiments Figure 2 . Detailed Description of the Embodiment
[0013] AsFigures 1 to 2 As shown in the figure, a clamping head for welding the end of a twist drill bit includes a rectangular plate 1. A pair of guide holes 10 are respectively opened at both ends of the rectangular plate 1. The length direction of the guide holes 10 is parallel to the length direction of the rectangular plate 1. Connecting screws 2 are inserted through the guide holes 10. Lower moving plates 20 are respectively provided at the lower ends of the connecting screws 2 at the same end. The lower moving plates 20 are located on the lower side of the rectangular plate 1. A moving plate 21 is provided on the lower moving plate 20. A movable long hole 22 is opened on the moving plate 21. The upper end of the movable long hole 22 extends inwardly and obliquely. A pressure rod 23 is inserted through the movable long hole 22. A concave-shaped moving seat 24 is provided on the pressure rod 23. A connecting arm is provided at the lower end of the moving plate 21. An installation lower plate 25 is installed at the lower end of the connecting arm. A rotating seat 26 is installed inside the installation lower plate 25. A clamping wheel 27 is rotatably provided at the inner end of the rotating seat 26. A servo motor 3 is installed on the rectangular plate 1. A lead screw 30 is connected to the output shaft of the servo motor 3. A moving nut 31 is provided on the lead screw 30. A movable block 32 is provided at the lower end of the moving nut 31. A moving rotating seat 33 is installed at the lower end of the movable block 32. A driving wheel 34 is rotatably provided at the inner end of the moving rotating seat 33. One end of the driving wheel 34 is connected with a driven bevel gear 35. A driving bevel gear 36 is engaged with the driven bevel gear 35. A driving motor 37 is connected to the driving bevel gear 36. The driving motor 37 is installed on the movable block 32 through a mounting plate 38. During clamping, the clamping wheels 27 and the driving wheels 34 are arranged in a circumferential array. Anti-slip patterns are provided on the outer peripheries of the clamping wheels 27 and the driving wheels 34.
[0014] During the operation of this embodiment, the operator transfers the twist drill bit between the clamping wheel 27 and the driving wheel 34.
[0015] Then, the servo motor 3 is started. Driven by the servo motor 3, the lead screw 30 will rotate. When the lead screw 30 rotates, it will drive the moving nut 31 to move outward. When the moving nut 31 moves, it will drive the driving wheel 34 to act on the outer periphery of the twist drill bit. And when the moving nut 31 moves, it will cause the pressure rod 23 to act on the movable long hole 22, thereby causing the moving plate 21 to drive the clamping wheel 27 to move inward, and until the clamping operation of the twist drill bit is completed by the clamping wheel 27 and the driving wheel 34.
[0016] Then, the clamping head is driven by a rotating device such as a motor or a rotating cylinder, so that the end of the twist drill bit is located below the laser welder, and the welding operation is carried out. During the welding operation, the driving motor 37 is started. Driven by the driving motor 37, the driving bevel gear 36 rotates. The rotation of the driving bevel gear 36 will drive the driven bevel gear 35 to rotate. This transmission method has high reliability. The rotation of the driven bevel gear 35 will drive the rotation of the driving wheel 34. The rotation of the driving wheel 34 will drive the twist drill bit to rotate, and the welding operation is completed during the rotation. The twist drill bit is flipped again, and then the other end of the twist drill bit is welded.
