Description

Technical Field

[0001] The utility model relates to the technical field of automobile guide arm processing, in particular to an automobile guide arm bracket locking structure. Background Art

[0002] The automobile guide arm is the main suspension component connecting the axle and the frame. Its function is to transmit the various forces and moments between the axle and the frame, and constrain the movement trajectory of the axle relative to the frame. The guide arm is generally installed on the automobile chassis as follows: the front end of the guide arm is hinged to the frame through a bushing, the middle straight section is rigidly fixed to the axle, and the rear end is connected to the frame through an air spring.

[0003] During the welding process of the automobile guide arm bracket, it is necessary to use a clamping tool to clamp and position the guide arm bracket to ensure the accuracy of the welding position.

[0004] However, since the guide arm bracket is a special-shaped part, when using traditional clamping tooling to clamp and fix it, the shape of the clamping head cannot adapt well to the overall shape structure of the guide arm, resulting in a weak clamping effect, affecting the stability during welding. In addition, the traditional clamping tooling is only applicable to the same model of guide arm brackets and has low versatility. Utility Model Content

[0027] See also Figures 1-4 The utility model provides a locking structure for a car guide arm bracket, including a base 1, a driving mechanism 2, a pair of upright frames 3 and a pair of clamping heads 5. The driving mechanism 2 is arranged on the base 1, and the two upright frames 3 are symmetrically arranged above the base 1 through the driving mechanism 2. The driving mechanism 2 is used to drive the two upright frames 3 to move closer to or away from each other. A shaft rod 4 is installed on the top of the two upright frames 3, and a clamping head 5 is installed at the end of the two shaft rods 4 that are close to each other. A number of L-shaped arms 6 are respectively installed on the outer edges of the two clamping heads 5, and the L-shaped arms 6 can be rotated and adjusted around the axis of the clamping head 5. Each L-shaped arm 6 is provided with a pair of interference fastening mechanisms 7, which are used to limit the interference of the guide arm bracket.

[0028] When the locking structure provided by the present invention is used to lock the automobile guide arm bracket for welding processing, the automobile guide arm bracket is placed horizontally between the two clamping heads 5, and then the two vertical frames 3 are driven to approach each other by operating the driving mechanism 2, and the two clamping heads 5 are driven to approach each other, and finally the guide arm bracket is clamped and initially fixed from both sides, and then the L-shaped arms 6 on both sides are rotated and adjusted to the appropriate position, and then the guide arm bracket is tightened by operating the contact and tightening mechanisms 7, thereby providing a multi-point tightening effect, which can firmly lock the guide arm bracket and ensure stability during welding processing.

[0029] Specifically, the driving mechanism 2 includes a guide seat 21, a two-way threaded rod 22, a rocker 23 and a nut seat 24. The guide seat 21 is fixed on the upper surface of the base 1. A guide groove 211 is provided on the top of the guide seat 21. The two-way threaded rod 22 is rotatably installed in the guide groove 211, and one end extends through and extends to the outer side of the guide seat 21, and is installed with a rocker 23. The two nut seats 24 are symmetrically limited and slidably installed in the guide groove 211, and are threadedly fitted on both sides of the two-way threaded rod 22. The two uprights 3 are respectively fixed vertically on the top of the corresponding nut seats 24. The two-way threaded rod 22 is rotated by shaking the rocker 23. The rotating two-way threaded rod 22 threadably drives the two nut seats 24 to approach or move away from each other, thereby driving the upright 3, the shaft 4 and the clamping head 5 to move synchronously, providing drive for the clamping and releasing actions of the two clamping heads 5.

[0030] Specifically, the interference fastening mechanism 7 includes an adjusting screw 72, an interference fastening head 73 and a first twist handle 74. A pair of threaded holes 71 are provided on the L-shaped arm 6. The two adjusting screws 72 are respectively threadedly matched and installed in the threaded holes 71. One end of the adjusting screw 72 is fixed with an interference fastening head 73, and the other end is installed with a first twist handle 74. After the guide arm bracket is clamped by the two clamping heads 5, the adjusting screw 72 is tightened by pinching each first twist handle 74 respectively. The adjusting screw 72 pushes each interference fastening head 73 to interfere with the outer wall of the guide arm bracket, thereby realizing multi-point interference limiting of the guide arm bracket after re-clamping.

[0031] Specifically, an annular groove 61 with a T-shaped cross-section is provided on the outer edge wall of the stand 3, and a T-shaped block 62 is fixed on the end of the L-shaped arm 6. Each T-shaped block 62 is slidably installed in the corresponding annular groove 61. By sliding the T-shaped block 62 in the annular groove 61 and then installing the L-shaped arm 6 on the T-shaped block 62, the L-shaped arm 6 has the ability to rotate and adjust around the axis of the clamping head 5, which makes it easier to adjust the interference and fastening mechanism 7 to a suitable position for interference and fastening.

[0032] Specifically, the surfaces of the two clamping heads 5 that are away from each other are respectively provided with four arc-shaped guide openings 63 that are connected to the annular groove 61. The side of each T-shaped block 62 is fixed with a fastening bolt 64. Each fastening bolt 64 passes through the corresponding arc-shaped guide opening 63 and extends to the outside of the clamping head 5. Each fastening bolt 64 is threadedly matched with a fastening nut 65 that can interfere with the side surface of the clamping head 5. By tightening the fastening nut 65 on the fastening bolt 64 and using the fastening nut 65 to cling to the outer wall of the clamping head 5, the L-shaped arm 6 can be limited to prevent the L-shaped arm 6 from rotating at will. When the position of the L-shaped arm 6 needs to be adjusted, the fastening nut 65 can be loosened.

[0033] Specifically, both shafts 4 are rotatably mounted on the stand 3 , and one of the stands 3 is provided with an adjustment mechanism 8 , which is used to drive the corresponding shaft 4 to rotate.

[0034] The adjusting mechanism 8 includes a side frame 81 and a worm 82 , wherein a worm wheel 84 is fixed to the end of the one side shaft 4 away from the clamping head 5 , and the worm 82 is rotatably mounted on the side of the stand 3 through the side frame 81 , and the worm 82 is correspondingly engaged with the worm wheel 84 .

[0035] A second torsion handle 83 is mounted on one end of the worm 82 .

[0036] By pinching the second twist handle 83 to twist the worm 82, the rotating worm 82 engages and drives the worm wheel 84 to rotate, thereby driving the shaft 4 and the clamping head 5 on the same side to rotate, so that the locked guide arm bracket can be rotated and adjusted to change its direction to facilitate welding needs.

[0037] The one-way transmission effect of the worm 82 and the worm wheel 84 can achieve a self-locking effect, and when the worm 82 is not screwed to adjust, the guide arm bracket is prevented from rotating at will, which helps to maintain the state of the guide arm bracket.

[0038] In addition, the characteristics of the driving mechanism 2 driving the two upright frames 3 to move to different amounts, the L-shaped arm 6 being able to rotate around the clamping head 5 for fine-tuning of the position, and the adjusting screw 72 being able to be screwed for telescopic adjustment can be adapted to the locking needs of products of different models and have high versatility.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
