Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a positioning tooling with an anti-misplacement function. Background Art

[0002] The stabilizer bar is a component horizontally arranged at the front and rear ends of an automobile. The working principle of the stabilizer bar is based on its design structure. It is usually in a "U" shape and made of spring steel. Its main functions are to improve the driving stability of the automobile, enhance the vehicle's handling performance and reduce tire wear. Specifically, the automobile stabilizer bar resists the lateral force generated when the vehicle turns, restricts the roll angle of the vehicle body, and thus enhances the vehicle's stability. When the vehicle turns, the outer wheels are subjected to a greater lateral force (centrifugal force), resulting in the roll of the vehicle body. The stabilizer bar resists this lateral force, reduces the roll amplitude of the vehicle, and enables the vehicle to maintain better handling performance. In addition, the stabilizer bar can also reduce the wear of the tires caused by frequent adjustment of the driving direction during driving, thereby extending the service life of the tires. When the vehicle is driving straight, the deformations of the two sides of the suspension are the same, and the stabilizer bar does not work. However, when the vehicle turns, the roll of the vehicle body causes the inconsistent bouncing of the two sides of the suspension, and the outer suspension presses against the stabilizer bar, causing it to twist. The elastic force of the stabilizer bar prevents the wheels from lifting, so that the vehicle body can be kept balanced as much as possible, playing a role in lateral stability.

[0003] The stabilizer bar of an existing vehicle model looks similar to a left-right symmetric structure to the naked eye, but in fact, it is not completely symmetric left and right. There is a certain height difference between the lower edges of the left and right ends of the stabilizer bar, and this difference is very small and cannot be distinguished by the naked eye. When processing the stabilizer bar, two bushings need to be bonded to the middle part of the stabilizer bar, which requires positioning tooling to position the stabilizer bar. Due to the very small left-right structural difference of the stabilizer bar and the existing positioning tooling cannot distinguish the front and back sides of the stabilizer bar, after the existing positioning tooling positions the stabilizer bar, during the process of bonding the bushings, the resulting product will be unqualified due to the misplacement of the stabilizer bar. Summary of the Utility Model

[0004] The purpose of the present utility model is to solve the above problems, and a positioning tooling with an anti-misplacement function is designed, which solves the problem that the misplacement of the stabilizer bar caused by the existing positioning tooling not being able to identify the front and back sides of the stabilizer bar affects the bonding of the bushings.

[0005] To achieve the above purpose, the technical solution of the present utility model is that a positioning tooling with an anti-misplacement function includes:

[0006] Two positioning blocks corresponding to the positions at both ends of the product, and the two positioning blocks are provided with positioning grooves for positioning both ends of the product, and the shapes of the positioning grooves on the two positioning blocks respectively match the shapes of both ends of the product;

[0010] Wherein the distribution positions of the positioning blocks, the bushing bonding fixtures and the support rods are adapted to the overall shape of the product.

[0011] Preferably, one end of the positioning groove is through and the other end is not through.

Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0025] Such as Figure 1 and Figure 2As shown in the figure, a preferred embodiment of the present utility model proposes a positioning tooling with an anti-misplacement function. The positioning tooling mainly includes a base 6, a support rod 2, a positioning block 1, a bushing bonding fixture 3, a position adjusting device 4, a light sensor 5 and other components. Among them, there are two bases 6 and two positioning blocks 1. The placement positions of the two bases 6 correspond to the positions of the two ends of the stabilizer bar. The positioning block 1 is fixedly installed on the base 6. There are also two bushing bonding fixtures 3. The two bushing bonding fixtures 3 are located between the two bases 6 and are offset front and back from the bases 6. The support rod 2 is fixedly installed on the position adjusting device 4 and is located between one of the bases 6 and the bushing bonding fixture 3. The distribution positions of the two positioning blocks 1, the support rod 2 and the two bushing bonding fixtures 3 are adapted to the extension trajectory in the length direction of the stabilizer bar, and the whole stabilizer bar can be positioned and fixed.

[0026] Since the middle area of the stabilizer bar is a straight segment, the two bushing bonding fixtures 3 are located at both ends of the straight segment, close to the two ends of the stabilizer bar, and are used to bond the bushings to both ends of the straight ends of the stabilizer bar.

[0027] Reference Figure 3 , an installation groove is provided on the base 6, and an installation block 7 is fixedly installed in the installation groove through bolts. A plurality of bolt holes are provided on the installation block 7, and the positioning block 1 is fixedly installed on the installation block 7 through bolts.

[0028] The shape of the positioning block 1 is similar to an L shape. A positioning groove 101 is provided on each of the two positioning blocks 1. The extension trajectory and shape of the positioning groove 101 are respectively adapted to the shapes of the two ends of the stabilizer bar. One end of the positioning groove 101 is through, and the other end is not through. In this way, the two ends of the stabilizer bar can be respectively inserted into the two positioning grooves 101 and abutted against the inner wall of the positioning groove 101 to accurately position the stabilizer bar.

[0029] As Figure 3 shown, the position adjusting device 4 is located between one of the bases 6 and the bushing bonding fixture 3. The position adjusting device 4 is composed of a horizontal adjusting member 41, a vertical adjusting member 42 and a vertical adjusting member 43. Among them, the horizontal adjusting member 41 is perpendicular to and integrally connected to the vertical adjusting member 42. Strip-shaped holes are provided on the horizontal adjusting member 41, the vertical adjusting member 42 and the vertical adjusting member 43. The horizontal adjusting member 41 is fixedly installed on the outside of the base 6 through bolts, the vertical adjusting member 43 is fixedly installed on the vertical adjusting member 42 through bolts, and the support rod 2 is fixedly installed on the vertical adjusting member 43 through bolts. The horizontal, vertical and vertical positions of the support rod 2 can be adjusted through the strip-shaped holes on each adjusting member so that the placement position of the support rod 2 is adapted to the placement position of the stabilizer bar.

[0030] At the top of the support rod 2, there is a U-shaped avoidance groove, and the position of this avoidance groove corresponds to the position of the bent section of the stabilizer bar. When placed, the bent section of the stabilizer bar can pass through this avoidance groove. The opposed sensor 5 has a transmitting end and a receiving end, and the transmitting end and the receiving end are respectively located on both sides of the avoidance groove.

[0031] The height of the opposed sensor 5 is set. After the two ends of the stabilizer bar are respectively embedded into the positioning grooves 101 on the two positioning blocks 1, at this time, the straight section in the middle of the stabilizer bar is positioned by the bushing bonding fixture 3. During the process of bushing bonding, if the placement position of the stabilizer bar is correct (that is, the front side of the stabilizer bar is upward), at this time, the height of the lower edge of the stabilizer bar at the position where the opposed sensor 5 is located is higher than the height of the opposed sensor 5, and at this time, the signal emitted by the transmitting end of the opposed sensor 5 can be received by the receiving end.

[0032] On the contrary, if the stabilizer bar is misaligned, at this time, the height of the lower edge of the stabilizer bar at the position where the opposed sensor 5 is located is lower than the height of the opposed sensor 5, and at this time, the signal emitted by the transmitting end of the opposed sensor 5 is blocked by the stabilizer bar, and the receiving end cannot receive the signal, indicating that the two ends of the stabilizer bar are placed in the reverse direction, and thus the placement position of the stabilizer bar needs to be adjusted manually.

[0033] In other technical solutions, the height of the opposed sensor can also be adjusted higher. The opposed sensor 5 can detect the height of the upper edge of the stabilizer bar to determine whether the placement position of the stabilizer bar is accurate. The determination principle is opposite to the principle of the above solution. If the receiving end can receive the signal emitted by the transmitting end, it indicates that the placement position of the stabilizer bar is in the reverse direction; if the receiving end does not receive the signal emitted by the transmitting end, it indicates that the placement position of the stabilizer bar is correct.

[0034] As Figure 4 shown, the bushing bonding fixture 3 is composed of an upper fixture 32 and a lower fixture 31. The bottom surface of the upper fixture 32 and the upper surface of the lower fixture 31 both have grooves. After the upper fixture 32 approaches the lower mold, the two grooves will enclose to form a cavity, and the diameter of this cavity is adapted to the diameter of the bushing.

[0035] After placing the unbonded bushing into the groove on the lower fixture 31, then place the stabilizer bar and identify the placement position of the stabilizer bar. Then cover the upper fixture 32 on the lower fixture 31. At this time, use the hydraulic equipment to press the upper fixture 32 downward so that the upper fixture 32 approaches the lower fixture 31. At this time, the bushing tightly surrounds the stabilizer bar under the action of pressure, thereby bonding the bushing and the stabilizer bar together.

[0036] Locking clamps 33 are hinged on both sides of the lower fixture 31. At the same time, protrusions that cooperate with the locking clamps 33 are provided on both sides of the upper fixture 32. After the bushing is pressed and shaped, the upper fixture 32 and the lower fixture 31 are tightly held together by the locking clamps 33. Then, the hydraulic equipment can be removed, and the stabilizer bar and bushing bonding fixture 3 can be placed in a high-temperature environment for baking so that the bushing can be completely shaped and tightly locked on the stabilizer bar.

[0037] The specific principle is to first adjust the position of the support rod 2, place the stabilizer bar, and the opposed sensors 5 identify the placement position of the stabilizer bar. If the placement position is correct, the signals of the opposed sensors 5 are connected. At this time, the operator presses the downward switch of the hydraulic equipment, and the hydraulic equipment presses down the bushing bonding tooling, and the bushing and the stabilizer bar are bonded together through the bushing bonding tooling. Since the hydraulic equipment and the opposed sensors are signal-connected, if the placement position of the stabilizer bar is incorrect, the signals of the opposed sensors 5 are not conducted, and at the same time, the opposed sensors 5 will send a signal to stop working to the hydraulic equipment. Therefore, when the operator presses the downward switch of the hydraulic equipment at this time, the hydraulic equipment will not work and will automatically alarm, and the red signal light will be on.

[0038] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made by those skilled in the art to some parts thereof all reflect the principles of the present invention and fall within the protection scope of the present invention.
