DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] The embodiment of the present application provides a clamping device for connector welding, such as Figure 1 and Figure 2 As shown, it includes: a support rod 1, a round table 2, a clamping plate 3, a strap 4, and a fixing mechanism 5.

[0021] Among them, the number of support rods 1 is two pairs and they are mounted in parallel on a truncated table 2. The two support rods 1 are arranged in parallel, and the middle parts of the two support rods 1 protrude toward the truncated table 2 to form a V-shaped frame 11; the number of clamping plates 3 is two pairs and they are respectively installed on the support rods 1 at both ends of the V-shaped frame 11. The two clamping plates 3 are arranged perpendicular to the support rods 1 and move toward each other along the length direction of the support rods 1. Specifically, guide grooves 12 arranged along the length direction of the two support rods 1 at both ends of the V-shaped frame 11 are provided on the opposite surfaces of the two support rods 1 at the two ends of the V-shaped frame. Guide blocks 33 are provided at both ends of the clamping plates 3. The guide blocks 33 are respectively matched in the corresponding guide grooves 12. The two clamping plates 3 and the V-shaped The distance between the frames 11 is always equal. A strip hole 31 is provided on the clamping plate 3 along the length direction of the clamping plate 3. The strip hole 31 is located above the support rod 1 and is arranged parallel to the frustum 2. If the strip hole 31 is located below the support rod 1, the length of the strap 4 is required to be longer. At the same time, after the strap 4 is tightened, it is not conducive to the movement of the clamping plate 3. Providing the strip hole 31 above the support rod 1 not only saves the length of the strap 4, but also improves the convenience of device operation; the two ends of the strap 4 are respectively passed through the strip holes 31 on the corresponding clamping plates 3; the fixing mechanism 5 is provided on both sides of the two clamping plates 3 for fixing the ends of the strap 4.

[0022] This embodiment uses circular and rectangular connector shells as examples. When used, the strap 4 is in a free state, and the operator places the circular or rectangular connector shell. If it is a circular shell, the shell is placed on the V-shaped frame 11 so that the V-shaped frame 11 is against the circumference of the circular shell; if it is a rectangular shell, its two ends are placed on the support rods 1 at both ends of the V-shaped frame 11, and the V-shaped frame 11 is located directly below the shell, and its pins are kept perpendicular to the support rods 1. At the same time, the strap 4 is located above the shell; after the shell is placed, the two ends of the strap 4 are pulled at the same time so that the strap 4 is against the upper end of the shell, and the fixing mechanism 5 is operated to fix the two ends of the strap 4; then the two clamping plates 3 approach each other, and as the two clamping plates 3 approach, the strap 4 gradually fits the upper end surface of the shell until the strap 4 presses the shell tightly against the V-shaped frame 11 or the support rod 1, and the clamping plate 3 stops moving, thus achieving clamping and fixing of the shell. When the two clamping plates 3 are against the two sides of the connector shell, the strap 4 can adapt to the outer contour of the shell, and the V-shaped frame 11 or the support rod 1 supports the bottom of the shell, thereby achieving clamping and fixing of electrical connector shells of various shapes or sizes, replacing the manual fixation method, and at the same time improving the versatility of the device and the quality of welding.

[0023] Specifically, such as Figure 1 and Figure 2As shown, a pair of support plates 21 are vertically arranged on the truncated table 2 and arranged parallel to each other. The support rod 1 is connected between the two support plates 21. A screw 22 is arranged to rotate along its own axis between the two support plates 21. The threads at both ends of the screw 22 rotate in opposite directions. The screw 22 is parallel to the truncated table 2 and arranged in the length direction of the support rod 1. A motor 23 is provided on the outside of the support plate 21, and its driving end is connected to one end of the screw 22. A matching block 32 is connected below the clamping plate 3. The matching block 32 has a through hole, and the through hole is provided with an internal thread that matches the screw 22. The matching block 32 passes through the through hole on the screw 22. When used, the two clamping plates 3 can be moved closer or separated by the forward and reverse rotation of the motor 23. The motor 23 drives the screw 22 to rotate around its own axis. At the same time, with the cooperation of the matching block 32 and the screw 22, the two clamping plates 3 are moved towards each other with a single power source, which optimizes the structure of the device and saves the production cost of the device.

[0024] Specifically, such as Figure 1 and Figure 3 As shown, the fixing mechanism 5 includes a matching platform 51 installed at the end of the support rod 1 and arranged parallel to the circular table 2, the height of which is adapted to the height of the strip hole 31, and the height of the matching platform 51 should be consistent with the height of the strip hole 31, so as to facilitate pulling and fixing the strap 4, and a pair of guide rods 52 are vertically provided on the matching platform 51, and the ends of the guide rods 52 are connected to limit plates 53 arranged parallel to the matching platform 51, and a pressure plate 54 is arranged parallel to the top of the matching platform 51, and its two ends are passed through the guide rods 52, and a spring 55 is sleeved on the guide rod 52. When the spring 55 is in a natural state, the pressure plate 54 is pressed on the matching platform 51, and the spring 55 is connected between the limit plate 53 and the pressure plate 54. A pull rod 56 is vertically provided on the pressure plate 54, and one end of the pull rod 56 is passed through the limit plate 53 and is connected to a pull ring 57. When in use, the two ends of a lifting rod can be passed through the pull rings 57 of the fixing mechanism 5 on both sides of the two clamping plates 3, and a linear mechanism can be set above the lifting rod. The movable end of the linear mechanism is perpendicular to the table 2 and connected to the middle of the lifting rod. When it is necessary to pull the two ends of the strap 4, the linear mechanism drives the lifting rod to rise, thereby pulling up the pressure plate 54 to release the fixation of the strap 4. When it is necessary to fix the strap 4, the lifting rod is driven down. Under the action of the spring 55, the end of the strap 4 is pressed and fixed by the pressure plate 54, which further simplifies the operation of the device and improves the convenience of the device.

[0025] Preferably, Figure 3 As shown, in order to further fix the strap 4 and prevent it from slipping, brake pads 58 can be provided on the top surface of the mating platform 51 and the bottom surface of the pressure plate 54. The brake pads 58 can be made of rubber or nylon with a large friction coefficient.

[0026] Preferably, Figure 1As shown, the frustum 2 is embedded in a base 6 and is rotatable around its own axis, which facilitates adjustment of the position of the connector housing according to actual conditions during welding, and facilitates accurate docking of one end of the plug-in pin with the wire, thereby improving the flexibility of the device and the welding quality.

[0027] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
