Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing, specifically referring to an automotive stabilizer bar bushing press-fitting machine. Background Technology

[0002] A stabilizer bar, also known as an anti-roll bar or balance bar, is a crucial component of a car's suspension system. Its primary function is to suppress body roll during cornering, thereby improving vehicle stability and handling. During the manufacturing and assembly of a stabilizer bar, bushings are press-fitted to the bar head. These bushings reduce vibration and noise during operation, prevent direct friction between the stabilizer bar and other components, and extend its lifespan. Therefore, the quality of the bushing press-fit directly affects the overall performance of the stabilizer bar and the vehicle's driving safety.

[0003] Most existing press-fit machines use a single fixed structure to clamp stabilizer bars. While this is efficient for mass production of a single specification, it is inefficient because stabilizer bars for different car models vary in diameter, length, and other specifications. Each time the stabilizer bar model is changed, the corresponding clamping fixture needs to be replaced, impacting overall production efficiency. Secondly, the pressing and clamping mechanisms of traditional press-fit machines are independent. After clamping and fixing the stabilizer bar, the position of the pressing mechanism needs to be adjusted to ensure alignment with the bushing installation position of the stabilizer bar head. Manual adjustment can easily lead to positioning deviations, resulting in incomplete or misaligned bushing pressing, affecting the assembly accuracy of the stabilizer bar and potentially damaging it or the bushing, increasing production costs. Utility Model Content

[0004] The present invention mainly addresses the aforementioned technical problems.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: The automotive stabilizer bar bushing pressing machine proposed by this utility model includes a base, the upper part of which has a limit groove, and also includes a drive mechanism, a connecting component, and a pressing mechanism:

[0006] The drive mechanism is located inside the limiting groove and includes two symmetrical movable frames, which are slidably fitted into the limiting groove.

[0007] The connecting component is slidably disposed on the upper part of the base, and one end is fixedly connected to the movable frame;

[0008] The pressing mechanism is located at the other end of the upper part of the connecting assembly.

[0009] Furthermore, the drive mechanism also includes a motor and a lead screw. The motor is fixed to the outside of the base, and the lead screw is rotatably located inside the limiting groove, with one end passing through the base and the motor shaft.

[0010] Furthermore, the lead screw adopts a double-ended screw structure with opposite thread structures on both sides, and the two ends are respectively perpendicularly threaded through the moving frame. A clamping plate is fixed on the upper part of the moving frame to control the moving frame and the clamping plate to move towards each other.

[0011] Furthermore, the connecting component includes a movable plate, and the upper part of the base has a guide groove parallel to the limiting groove. One end of the movable plate is fixedly connected to the movable frame, and the lower part is slidably engaged with the guide groove.

[0012] Furthermore, the pressing mechanism includes an electric telescopic rod and a pusher, the fixed end of the electric telescopic rod is fixedly mounted on the upper part of the movable plate, and the pusher and the movable end of the electric telescopic rod are fixedly connected.

[0013] Furthermore, the adjacent surfaces of the two sets of clamping plates are provided with symmetrical trapezoidal concave surfaces, and the adjacent surfaces of the two sets of pushing blocks are also provided with symmetrical trapezoidal concave surfaces, and the two sets of trapezoidal concave surfaces are completely on the same plane.

[0014] The beneficial effects of this utility model by adopting the above structure are as follows:

[0015] 1. The automotive stabilizer bar bushing press-fitting machine proposed in this solution controls the two moving frames and clamping plates to move in opposite directions through a drive mechanism. Combined with the trapezoidal concave surface opened on the clamping plate, it can adapt to automotive stabilizer bars of different diameters without changing the clamping fixtures. This improves the equipment's adaptability to clamping different models of stabilizer bars, reduces the time for changing fixtures, and increases production efficiency.

[0016] 2. The automotive stabilizer bar bushing press-fitting machine proposed in this solution connects the drive mechanism and the press-fitting mechanism through a connecting assembly. While the drive mechanism drives the clamping plate to clamp the stabilizer bar, it also simultaneously drives the moving plate and the press-fitting mechanism to move along the guide groove. This causes the trapezoidal concave surface on the inner side of the push block to automatically align with the outer ring of the stabilizer bar. Furthermore, the trapezoidal concave surfaces of the two clamping plates and the push block are on the same plane. There is no need for manual adjustment of the press-fitting mechanism position, which effectively avoids the problem of bushing incomplete or offset press-fitting caused by manual positioning deviation, and significantly improves the positioning accuracy and assembly quality of bushing press-fitting.

[0022] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof. Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, the present invention proposes an automotive stabilizer bar bushing press-fitting machine, which includes a base 1, a limiting groove 2 on the upper part of the base 1, a drive mechanism 3, a connecting component 4, and a press-fitting mechanism 5; the drive mechanism 3 is located inside the limiting groove 2 and includes two symmetrical moving frames 303, which are slidably fitted with the limiting groove 2, and the limiting groove 2 guides and limits the movement of the moving frame 303 to ensure that the moving frame 303 moves stably along a straight line.

[0025] like Figure 1-3 As shown, the drive mechanism 3 also includes a motor 301 and a lead screw 302. The motor 301 is fixed to the outside of the base 1, and the lead screw 302 is rotatably located inside the limiting groove 2. One end of the lead screw 302 passes through the base 1 and is shaft-connected to the motor 301. The motor 301 can drive the lead screw 302 to rotate stably within the limiting groove 2. The lead screw 302 adopts a double-ended screw structure with opposite thread structures on both sides, and both ends are perpendicularly threaded through the moving frame 303. The upper part of the moving frame 303 is fixed with a clamping plate 304. When the motor 301 drives the lead screw 302 to rotate, since the threads on both sides of the lead screw 302 are opposite, the two moving frames 303 will move in opposite directions or in the opposite direction along the limiting groove 2, thereby driving the clamping plate 304 to move synchronously, so as to clamp and fix the stabilizer bars of different diameter specifications. The adjacent surfaces of the two clamping plates 304 are provided with symmetrical trapezoidal concave surfaces. The trapezoidal concave surfaces can better fit with the outer circumferential surface of the stabilizer bar, improve the stability of the clamping, and prevent the stabilizer bar from rotating or shifting during the pressing process.

[0026] like Figure 1-2As shown, the connecting component 4 is slidably disposed on the upper part of the base 1, and one end is fixedly connected to the movable frame 303. The connecting component 4 includes a movable plate 401. The upper part of the base 1 is provided with a guide groove 402 parallel to the limiting groove 2. One end of the movable plate 401 is fixedly connected to the movable frame 303, and the lower part is slidably engaged with the guide groove 402. When the movable frame 303 moves along the limiting groove 2, it will drive the movable plate 401 to slide synchronously along the guide groove 402. The guide groove 402 guides the movement of the movable plate 401, ensuring the accuracy of the movement direction of the movable plate 401.

[0027] like Figure 1-4 As shown, the pressing mechanism 5 is located at the other end of the upper part of the connecting assembly 4. The pressing mechanism 5 includes an electric telescopic rod 501 and a pushing block 502. The fixed end of the electric telescopic rod 501 is fixed to the upper part of the moving plate 401. The pushing block 502 and the movable end of the electric telescopic rod 501 are fixedly connected. When the electric telescopic rod 501 extends or retracts, it can drive the pushing block 502 to move back and forth, thereby realizing the pressing operation of the bushing. The adjacent surfaces of the two sets of pushing blocks 502 are also provided with symmetrical trapezoidal concave surfaces, and the two sets of trapezoidal concave surfaces are completely on the same plane. The trapezoidal concave surfaces can fit with the outer circumference of the bushing, ensuring that the bushing is subjected to uniform force during pressing. At the same time, since the clamping plate 304 and the trapezoidal concave surfaces of the pushing block 502 are on the same plane, when the driving mechanism 3 drives the clamping plate 304 to clamp the stabilizing rod, the trapezoidal concave surfaces of the pushing block 502 will automatically align with the outer ring of the stabilizing rod without manual adjustment.

[0028] This press-fitting machine also includes a control chip, which is electrically connected to the electric telescopic rods 501 on both sides. The control chip is used to control the electric telescopic rods 501 on both sides to start synchronously, so as to ensure that the push blocks 502 on both sides press the bushing synchronously, and further ensure that the bushing is subjected to uniform force.

[0029] In practical use, the stabilizer bar to be fitted with the bushing is placed between the two clamping plates 304. The motor 301 is started, and the motor 301 drives the lead screw 302 to rotate. Under the guidance of the limiting groove 2, the two moving frames 303 drive the clamping plates 304 to move towards each other until the trapezoidal concave surface on the clamping plate 304 is tightly fitted with the outer circumference of the stabilizer bar, thus completing the clamping and fixing of the stabilizer bar. While the moving frame 303 moves, it will drive the moving plate 401 fixed to it to slide synchronously along the guide groove 402, thereby driving the pressing mechanism 5 to move, so that the trapezoidal concave surface on the inner side of the pushing block 502 is relatively fitted with the outer ring of the stabilizer bar. Then, the bushing is fitted onto the head of the stabilizer bar. The electric telescopic rods 501 on both sides are started through the control chip. The electric telescopic rods 501 on both sides extend synchronously, driving the pushing block 502 to move towards the bushing, applying a uniform thrust to the bushing, and accurately pressing the bushing into the designated position of the stabilizer bar, thus completing the pressing operation.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
