In the existing stabilizer bar production process, in order to enhance the tensile force and strength of the workpiece and increase the anti-aging and elasticity of the bushing and stabilizer bar, it is usually necessary to pre-assemble the stabilizer bar and bushing before sending them to the vulcanization process together.

[0003] like Figure 1 The bushing includes an ear seat plate 100, a backing plate 101, a bushing A102, a bushing B103, a connecting pin 104 and a pin 105. The ear seat plate 100 is provided with a groove for placing the bushing A102 and the bushing B103. Both sides of the ear seat plate 100 and the backing plate 101 are provided with holes for the connecting pin 104 to pass through. The connecting pin 104 is provided with a through hole for the pin 105 to pass through. When assembling the bushing, The bushing A102, the stabilizer bar and the bushing B103 are sequentially placed into the grooves of the ear seat plate 100, and the bushing A102 and the bushing B103 are sleeved on the stabilizer bar.

When the guide block (541) completely enters the connecting sleeve (53), the connecting column (54) is in a vertical state. A spring (55) is arranged in the connecting sleeve (53) for driving the ball (531) to slide in a direction close to the workbench (21).

3. A stabilizer bar vulcanized bushing fixing and pressing device according to claim 2, characterized in that: The pressure head (51) is detachably arranged on the connecting column (54), a stud (511) is fixedly arranged on the pressure head (51), and a threaded groove matching the stud (511) is formed at the bottom end of the connecting column (54).

4. A stabilizer bar vulcanized bushing fixing and pressing device according to claim 1, characterized in that: A seesaw (22) is rotatably provided on the workbench (21), and a servo cylinder (23) is rotatably provided on the machine base (2). The piston rod of the servo cylinder (23) is hinged to the seesaw (22) and is used to drive the seesaw (22) to rotate so as to tilt the pressed-fitted stabilizing rod out of the clamping groove (321) of the ear seat plate (100).

5. A stabilizer bar vulcanized bushing fixing and pressing device according to claim 1, characterized in that: Positioning holes (322) for placing the connecting pins (104) are provided on the clamping block (32) and on both sides of the clamping slot (321).

6. A stabilizer bar vulcanized bushing fixing and pressing device according to claim 1, characterized in that: The base (31) is provided with a first compression spring (312) for driving the first clamping plate (33) to slide in a direction away from the base (31), and a second compression spring (313) for driving the second clamping plate (34) to slide in a direction away from the base (31).

7. A press-fitting method for fixing a stabilizer bar vulcanized bushing according to any one of claims 1 to 6, characterized in that: The following steps are involved: S1. Place the ear seat plates (100) in the card slots (321) of the two card seats (3). When installing the ear seat plates (100), place the bushing A (102) in the groove of the ear seat plates (100), and insert the connecting pins (104) into the holes on both sides of the ear seat plates (100); S2, driving the two pressing heads (51) to slide down, punching the ear seat plate (100) on the corresponding clamping seat (3), thereby correcting the position of the liner A (102) in the ear seat plate (100), and then raising and resetting the pressing head (51); S3, placing the middle part of the stabilizing rod into the grooves of the ear seat plates (100) on the two clamping seats (3), and placing the ends on both sides of the stabilizing rod into the positioning grooves (41) of the two positioning seats (4); S4. Insert bushings B (103) into the grooves of the two ear seat plates (100), then place pads (101) on the tops of the two ear seat plates (100), and insert the connecting pins (104) on both sides of the ear seat plates (100) into the corresponding holes on both sides of the ear seat plates (100); S5, the pressure head (51) is driven down again to punch the pad (101), and the bushing B (103) after punching is compressed and enters into the groove of the ear seat plate (100), and the bushing A (102) and the bushing B (103) are sleeved on the stabilizing rod, and the position of the pad (101) also drops to fit with the top of the ear seat plate (100); S6. Keep the pressure head (51) in a pressed state, insert the pins (105) into the through holes of each connecting pin (104), then raise and reset the pressure head (51), and then take the stabilizing bar together with the bushing on the stabilizing bar out of the slot (321) of the mounting seat (3), thus completing the press-fitting and fixing of the bushing and the stabilizing bar.
