Description

Technical Field

[0001] The utility model relates to the technical field of connector fixtures, in particular to an adjustable connector fixture. Background Art

[0002] Connector fixtures are special tools that are mainly used to fix, clamp and support connectors or other related workpieces to ensure that they maintain a specific position and direction during manufacturing, assembly, maintenance and inspection. This fixture usually consists of a fixture base, fixture elements and a clamping mechanism. The clamping position can be precisely adjusted manually or mechanically. Connector fixtures play a vital role in the production process of electronic products. It can help workers accurately position and fix connectors, thereby improving production efficiency and ensuring product quality. In addition, fixtures also help improve workers' working conditions, reduce errors caused by human factors, and ensure production safety.

[0003] For example, the Chinese authorized patent "A connector fixture" with announcement number CN216991590U includes a mounting plate 1, a mounting plate 2 is mounted on the upper surface of the mounting plate 1, an outer cylinder is mounted on the top of the mounting plate 2, and a plug-in column is arranged on the inner shaft of the outer cylinder. The connector fixture inserts the connector into the interior of the boom top seat through the slot of the groove, and the connector is in the notch of the connector placement groove. At this time, the connecting shaft is controlled to move backward, and the external threaded pipe connected to its top is pulled to move backward. Because the plug-in column and the external threaded pipe are threadedly fixed, the plug-in column is also moved in the inner cavity of the outer cylinder toward the bottom end of the outer cylinder. After the boom top seat connected to the top of the plug-in column moves toward the inner cavity of the outer cylinder, the outer wall of the boom top seat has a gap, which ensures that the gap will shrink inward, so that the connector plugged in the groove can be squeezed and limited.

[0004] Although the above-mentioned existing technology can achieve clamping and fixing of connectors, the fixing effect for connectors of different diameters and lengths is poor, and the overall adjustment method is relatively complicated, which affects the processing efficiency of the connector. Therefore, it does not meet the existing needs. In this regard, we propose an adjustable connector tooling fixture. Utility Model Content

[0005] The purpose of the utility model is to provide an adjustable connector fixture to solve the problem of poor adjustment flexibility of the connector fixture proposed in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable connector fixture, comprising a base, movable seats are installed on both sides of the upper end surface of the base, and the movable seat is slidably connected to the base, and four annularly distributed sliding grooves are arranged on the inner side of the movable seat; and further comprising:

[0007] A clamping block is arranged inside the slide slot, and the clamping block and the slide slot are limited by sliding, a chuck is installed inside the movable seat, and the chuck is connected to the movable seat through a bearing, and four claws distributed in an annular shape are arranged inside the chuck, and the limiting thread on one side of the claw is engaged with the plane thread on the chuck, and the other side of the claw is fixed to the clamping block by a screw;

[0008] A worm wheel ring is arranged on the outer wall of the chuck, a worm is installed at the upper end inside the movable seat, the worm is rotatably connected with the movable seat, and the worm wheel ring is adapted to the worm.

[0010] Preferably, the front and rear inner walls of the upper end surface of the base are both provided with limit slide grooves, the front and rear ends of the movable seat are both provided with limit sliders, and the limit sliders are slidably matched with the limit slide grooves.

[0011] Preferably, mounting frames are installed at the lower ends of both sides of the base, and the upper horizontal plate of the mounting frame is slidably connected to the base, a plurality of equidistantly distributed positioning holes are arranged inside the upper horizontal plate of the mounting frame, positioning pins are arranged on both sides of the front end of the base, and the positioning pins are plugged into and fit with the positioning holes.

[0012] Preferably, an adjusting bolt is installed on one side of the upper horizontal plate of the mounting frame, and the adjusting bolt is threadedly matched with the mounting frame, and a mounting plate is installed on the lower end of the adjusting bolt, and the mounting plate is rotatably connected to the adjusting bolt.

[0013] Preferably, the polished rod at one end of the worm gear extends to the outside of the movable seat, and a hand wheel is fixedly mounted on the polished rod at one end of the worm gear.

[0014] Preferably, a rubber pad is provided on the inner wall of the clamping block.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can quickly fix connectors of different diameters. One end of the connector is placed at the center of the four clamping blocks. The user drives the worm to rotate by turning the hand wheel. The contact surface between the worm and the worm gear ring forms a spiral friction transmission surface. The rotation of the worm drives the worm gear ring to rotate, and then the chuck is driven to rotate by the worm gear ring. Since the limiting thread on one side of the claw is engaged with the plane thread on the chuck, the rotation of the plane thread drives the claw to approach the center, so that the claw drives the clamping block to approach the connector position until it fits therewith, thereby fixing one end of the connector. On the one hand, the clamping structure is easy to operate and can quickly clamp connectors of different diameters. On the other hand, the self-locking property of the worm and the worm gear ring is used to ensure that the chuck remains fixed at this position after adjustment, thereby improving the fixing effect of the clamping block on the connector.

[0017] 2. The utility model can adjust the distance between the two movable seats. After the staff fixes one end of the connector, the servo motor is turned on, and its output shaft drives the double-threaded transmission rod to rotate. Under the friction between its external thread and the screw hole in the sliding block, the rotational motion is converted into linear motion, so that the two sliding blocks drive the movable seats closer to each other, so that the other end of the connector can enter the installation position of the corresponding movable seat, so that the clamping block can fix the other end of the connector. This structure can be flexibly adjusted according to the length of the connector.

[0018] 3. The utility model has mounting frames installed on both sides of the base. By taking out the positioning pins, the mounting frames can be adjusted accordingly according to the width of the workbench of the installation equipment, so that the two sides of the mounting frames are clamped on the edges of the workbench, and then the positioning pins are inserted into the base to enter the positioning holes at the upper end of the mounting frames to fix the mounting frames. Then, the adjusting bolts are rotated to drive the mounting plate to move downward under the cooperation of the threads until it comes into contact with the upper end of the workbench, thereby fixing the base at this position, so as to adapt to various types of equipment workbenches.
