Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a tie rod arm processing fixture. Background Technology
[0002] Tie rods, tie rod assemblies, and connecting rod ball joints belong to the automotive steering system. The rear axle tie rod of a car is located on the rear axle and is an important connector linking the two rear wheels. It is also an important component to ensure safe driving. The tie rod connects the left and right steering arms, which can synchronize the two wheels and adjust the toe-in. The end of the tie rod is connected to the steering knuckle through a ball joint. Since directly turning the wheel requires a lot of force, most cars now use hydraulic steering to reduce the force required by the driver and make steering more flexible and easier to operate. The tie rod is an important part of the automotive steering mechanism.
[0003] When processing the tie rod arm, it is necessary to drill holes in it. However, most tie rod arms are irregular in shape and come in many different shapes, making it difficult to clamp them when drilling holes. The clamps need to be changed according to the shape of the tie rod, which not only reduces the processing efficiency of the device but also increases the labor intensity of the workers. Utility Model Content

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0020] Please see Figure 1-3 This utility model provides a technical solution: a horizontal tie rod arm processing fixture, including a processing table 1, clamping blocks 16 and adjusting screws 13. A placement plate 2 is fixedly installed on the top of the processing table 1, and the horizontal tie rod arm body 3 is placed on the top of the placement plate 2. There are three sets of clamping blocks 16. A drive motor 10 is provided on the processing table 1, and the drive motor 10 is used to drive the three sets of clamping blocks 16 to move. The adjusting screw 13 is located above the processing table 1 and is used to drive the clamping blocks 16 to move laterally.
[0021] Furthermore, two sets of fixed base plates 4 are fixedly installed at the bottom of the processing table 1. A bidirectional lead screw 5 is rotatably installed on the adjacent side walls of the two sets of fixed base plates 4. A guide rod 6 is fixedly installed on the adjacent side walls of the two sets of fixed base plates 4. A first moving horizontal plate 7 and a second moving horizontal plate 8 are slidably installed on the outer wall of the guide rod 6. Both the first moving horizontal plate 7 and the second moving horizontal plate 8 are threadedly installed with the bidirectional lead screw 5. A drive motor 10 is fixedly installed on one side of one set of fixed base plates 4. The rotating shaft of the drive motor 10 is fixedly installed with one end of the bidirectional lead screw 5. This arrangement allows the three sets of clamping blocks 16 to be moved. This allows the horizontal tie rod arm body 3 to be clamped when drilling holes in it, preventing the horizontal tie rod arm body 3 from moving. Furthermore, the clamping method of the three sets of clamping blocks 16 can clamp horizontal tie rod arm bodies 3 of different shapes, thereby increasing the applicability of the device.
[0022] Furthermore, a connecting rod 9 is fixedly installed on the top of both the first movable horizontal plate 7 and the second movable horizontal plate 8. A movable base plate 11 is fixedly installed on the top of the connecting rod 9. A mounting vertical plate 12 is fixedly installed on the top of the movable base plate 11. An adjusting screw 13 is threadedly installed on one side of the mounting vertical plate 12. One end of the adjusting screw 13 extends to the other side of the mounting vertical plate 12 and is rotatably mounted with a clamping block 16. A sliding rod 14 is slidably installed on one side of the mounting vertical plate 12. One end of the sliding rod 14 extends to the other side of the mounting vertical plate 12 and is connected to the clamping block 16. One side of the 6 is fixedly installed, and the other end of the adjusting screw 13 is rotatably installed with a connecting vertical plate 15. A handle is provided on one side of the connecting vertical plate 15. One end of the adjusting screw 13 is fixedly installed with one end of the handle. An opening is provided on the processing table 1 for the connecting rod 9 to move. One side of the clamping block 16 is arc-shaped. The bottom of the moving base plate 11 is in contact with the top of the processing table 1 but is not fixed. This setting allows for fine adjustment of 19 according to the shape of the horizontal tie rod arm body 3, which can further increase the applicability of the device and improve its practicality.
[0023] Working principle: In use, place the horizontal tie rod arm body 3 on the placement plate 2, and then rotate the adjusting screw 13. The rotation of the adjusting screw 13 drives the clamping block 16 to move. After all three sets of clamping blocks 16 are adjusted to the appropriate positions, the control drive motor 10 is started. The drive motor 10 drives the bidirectional lead screw 5 to rotate. The rotation of the bidirectional lead screw 5 drives the first moving horizontal plate 7 and the second moving horizontal plate 8 to move. The movement of the first moving horizontal plate 7 and the second moving horizontal plate 8 drives the moving base plate 11 to move through the connecting rod 9. The movement of the moving base plate 11 can move the clamping block 16, and thus clamp it. Then, holes are made in the horizontal tie rod arm body 3 through the opening setting.
[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
