Description

Technical Field

[0001] This utility model relates to an automatic clamping tool for welding electrical connectors, and more particularly to manual welding of weldable connectors in the process of cable assembly, belonging to the field of electronic assembly processing technology. Background Technology

[0002] With the continuous upgrading of my country's machinery and equipment and the increasing innovation capabilities, the demand for cable assemblies is constantly increasing, leading to a growing number of welded electrical connectors used in their production. The variety of connector models and specifications is also expanding, resulting in a significantly increased workload in the cable assembly manufacturing process. Due to the diverse types and small batch sizes of electrical connectors, welding has traditionally been a manual operation. Operators use flat-nose pliers to clamp and secure the connectors. This method suffers from unstable clamping and requires angle adjustments during welding, significantly impacting production efficiency. Furthermore, the clamping and angle adjustments during welding affect the quality of the outer shell plating and solder joints, posing quality risks. Utility Model Content

[0003] The present invention aims to solve the technical problems of low efficiency, high wrist strain on operators, and quality risks caused by the traditional flat-jaw pliers clamping method in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An automatic clamping fixture for welding electrical connectors includes a base, a moving beam, a spring, a fixed beam, a flat washer, an M8 spring washer, an M8 nut, an adjusting nut, a clamping block, a support column, a tie rod bolt, a tie rod, an M6 flat washer, an M6 nut, and a fixing screw.

[0006] The base is the bottom support structure of the clamp, and it has two pairs of threaded holes and T-slots symmetrically arranged along the center line. An adjusting nut is provided below the base.

[0007] The support column is a cylindrical structure with threads at both ends, with its bottom end located in a threaded hole on the base;

[0008] The support column is equipped with a movable beam below it and a fixed beam above it.

[0009] The spring is fitted onto the support column between the moving beam and the fixed beam through a shaft hole;

[0010] The movable beam is provided with a T-shaped groove, and the clamping blocks are respectively disposed in the T-shaped grooves on the base and the movable beam;

[0011] The fixed beam is fixed to the top of the support column by the flat washer, the M8 spring washer and the M8 nut;

[0012] The tie rod bolt is a shaft with threads at both ends, which is fixed to the center position of the moving beam through threaded engagement;

[0013] The tie rod is fixed to the tie rod bolt by the M6 ​​flat washer and the M6 ​​nut.

[0014] The fixed beam and the support column are connected by fixing screws.

[0015] The beneficial effects of adopting the above technical solution are:

[0016] Compared with existing welding clamping technologies, this invention features a simple structure and flexible operation. The detachable and replaceable clamping blocks are well-suited for welding workpieces of different specifications and types. Adjusting screws allow for adjustment of the welding surface angle to accommodate different operators' habits. Furthermore, the soft plastic material reduces heat conduction during welding and minimizes surface damage to the workpiece during clamping. This invention effectively solves the welding clamping problem for circular and rectangular welding connectors, improves manual welding efficiency, and reduces the strain on the operator's wrists.

[0020] Figure 3 This is a schematic diagram of the clamping of this utility model. Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings:

[0022] An automatic clamping fixture for welding electrical connectors includes a base 1, a moving beam 2, a spring 3, a fixed beam 4, a flat washer 5, an M8 spring washer 6, an M8 nut 7, an adjusting nut 8, a clamping block 9, a support column 10, a pull rod bolt 11, a pull rod 12, an M6 flat washer 13, an M6 nut 14, and a fixing screw 15.

[0023] The base 1 is the bottom support structure of the clamp, with two pairs of threaded holes and T-slots symmetrically arranged along the center line. An adjusting nut 8 is provided below the base 1, which can adjust the angle between the base 1 and the workbench surface, thereby adjusting the angle of the clamping surface to accommodate different operators and different products in the welding process, thus possessing versatility.

[0024] The support column 10 is a cylindrical structure with threads at both ends, and its bottom end is located in a threaded hole on the base 1;

[0025] A movable beam 2 is provided below the support column 10, and a fixed beam 4 is provided above it;

[0026] The spring 3 is fitted on the support column 10 between the moving beam 2 and the fixed beam 4 through the shaft hole, and during the operation of the clamp, the spring 3 compresses the moving beam 2 to form pressure in the axial direction of the support column 10.

[0027] The movable beam 2 is provided with a T-slot, and the clamping blocks 9 are respectively provided in the T-slots on the base 1 and the movable beam 2. The clamping blocks 9 that come into contact with the connector product are made of a softer material, such as PPS, which can ensure that the connector shell is not damaged and also reduce heat conduction. The clamping blocks 9 adopt a detachable T-slot structure, and clamping blocks with different clamping surfaces can be selected according to rectangular connectors or circular connectors.

[0028] The fixed beam 4 is fixed to the top of the support column 10 by the flat washer 5, the M8 spring washer 6 and the M8 nut 7;

[0029] The tie rod bolt 11 is a shaft with threads on both ends, which is fixed to the center position of the moving beam 2 by thread engagement;

[0030] The tie rod 12 is fixed to the tie rod bolt by the M6 ​​flat washer 13 and the M6 ​​nut 14;

[0031] The fixed beam 4 and the support column 10 are connected by fixing screws 15.

[0032] In use, the movable beam 2 is moved upward by the pull rod 12 on the movable beam 2, so that the upper and lower clamping blocks 9 are separated to make room for clamping. The electrical connector to be welded is placed on the clamping surface, and the pull rod 12 is released so that the upper clamping block contacts the connector. The movable beam 2 is clamped by its own weight and the spring force provided by the spring 3. At the same time, the larger the workpiece, the greater the spring compression ratio and the greater the clamping force, which can ensure the reliability of workpiece clamping. After clamping, the angle is adjusted by adjusting the nut 8 according to the workpiece and the operator's usage habits, and then the welding operation is carried out.
