Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically a device for pressing and locking engine rubber suspensions. Background Technology

[0002] The conventional method for assembling engine rubber mounts relies on manual, step-by-step operations, which cannot achieve automated mass production, resulting in long production cycles and low efficiency. Workers need to repeatedly perform manual adjustments, which is labor-intensive and can easily lead to fatigue, affecting the consistency of quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a device for press-fitting and locking engine rubber mounts. This device enables mass production of press-fitting and locking of specific irregularly shaped mount products, solving efficiency issues and reducing the workload of workers. By implementing the sequential action of press-fitting followed by locking, the vulcanized body can enter the cavity accurately and laterally in one go, ensuring dimensional accuracy and appearance quality. Furthermore, the use of a combination of wedges and sliders solves the problem of irregularly shaped inserts collapsing under conventional working methods.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a device for pressing and locking engine rubber suspension, comprising an upper base plate and a lower base plate arranged opposite to each other, and further comprising a sliding plate and a limiting device; a wedge block is provided on the lower base plate; the upper base plate is used to press down the sliding plate; the sliding plate is movably mounted on the lower base plate, and the sliding plate has a positioning groove for the wedge block to pass through, and a slider adapted to the wedge block is provided in the positioning groove. When the sliding plate is pressed down, the wedge block enters the positioning groove and squeezes the slider to move horizontally, completing the locking operation; the height of the limiting device is greater than the height of the wedge block, and the limiting device is placed between the lower base plate and the sliding plate. After the pressing operation is completed, the limiting device is removed.

[0005] A further improvement is that a pressure plate is provided at the bottom of the upper base plate.

[0006] A further improvement is that: the sliding plate is provided with a mounting groove, the mounting groove is provided with a return spring, one end of the return spring abuts against the slider, and the other end of the return spring abuts against the inner wall of the mounting groove.

[0007] A further improvement is that the sliding plate is also provided with a cover plate for closing the mounting groove.

[0008] A further improvement is that a positioning pin is provided on the sliding plate.

[0009] A further improvement is that the limiting device includes a U-shaped limiting frame, and a handle is provided at the rear end of the limiting frame. The handle is connected to the lower base plate by an elastic rope.

[0010] A further improvement is that baffles are provided on both sides of the wedge block on the lower base plate.

[0011] A further improvement is that: a guide sleeve is provided on the bottom surface of the upper base plate, the sliding plate slides on the guide post, and a guide post adapted to the guide sleeve is provided on the upper base plate.

[0012] A further improvement is that a limit block is provided at the lower end of the guide post. The height of the limit block is less than the height of the wedge block, which is used to limit the descent height of the sliding plate.

[0013] A further improvement is that a positioning post is provided on the lower base plate, the upper end of which slides through the sliding plate, and a buffer spring is sleeved on the positioning post, with the two ends of the buffer spring abutting against the sliding plate and the lower base plate respectively.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0034] See Figures 1-7As shown, this utility model embodiment provides a device for pressing and locking engine rubber mounts, including an upper base plate 2 and a lower base plate 1 arranged opposite to each other, and also includes a sliding plate 3 and a limiting device 4;

[0035] A wedge block 15 is provided on the lower base plate 1; baffles 16 are provided on both sides of the wedge block 15 on the lower base plate 1. Specifically, a guide sleeve 22 is provided on the bottom surface of the upper base plate 2, and the sliding plate 3 slides on the guide post 11. The upper base plate 2 is provided with a guide post 11 that is adapted to the guide sleeve 22. A limit block 14 is provided at the lower end of the guide post 11. The height of the limit block 14 is less than the height of the wedge block 15, which is used to limit the descent height of the sliding plate 3. To ensure the wear resistance of the wedge, a stop block 36 is designed, and oil grooves are designed on all contact sliding parts.

[0036] The upper base plate 2 is used to press down the sliding plate 3; specifically, a pressure plate 21 is provided at the bottom of the upper base plate 2.

[0037] The sliding plate 3 is vertically detachable and mounted on the lower base plate 1. The sliding plate 3 has a positioning groove 31 through which the wedge block 15 passes. A slider 32, adapted to the wedge block 15, is installed within the positioning groove 31. When the sliding plate 3 is pressed down, the wedge block 15 enters the positioning groove 31 and presses the slider 32 to move horizontally, completing the locking operation. Specifically, the sliding plate 3 has an installation groove containing a return spring 33. One end of the return spring 33 abuts against the slider 32, and the other end abuts against the inner wall of the installation groove. The sliding plate 3 also has a cover plate 34 for sealing the installation groove, ensuring the reliability of the return spring and the installation groove. A positioning pin 35 is provided on the sliding plate 3. A positioning post 12 is provided on the lower base plate 1. The upper end of the positioning post 12 slides through the sliding plate 3, and a buffer spring 13 is sleeved on the positioning post 12. The two ends of the buffer spring 13 abut against the sliding plate 3 and the lower base plate 1, respectively.

[0038] The height of the limiting device 4 is greater than the height of the wedge block 15. The limiting device 4 is placed between the lower base plate 1 and the sliding plate 3. After the pressing operation is completed, the limiting device 4 is removed. Specifically, the limiting device 4 includes a U-shaped limiting frame 41, and a handle 42 is provided at the rear end of the limiting frame 41. The handle 42 is connected to the lower base plate 1 through an elastic rope 43.

[0039] The working principle of this utility model:

[0040] The pre-installed suspension spring vulcanized body and outer frame are positioned on the sliding plate. Using the downward pressing motion of the equipment and under the constraint of the limiting device, the vulcanized body is first pressed into the shell. Then, the limiting device is removed, and again, under the downward pressing motion of the equipment and the action of the wedge tooling, the transverse slider moves laterally, completing the bending and locking of the insert. This invention enables mass production of press-fitting and locking of specific irregularly shaped suspension products, solving efficiency problems and reducing the workload of workers. Because it achieves the sequential action of press-fitting followed by locking, the vulcanized body can enter the cavity accurately and lock laterally in one go, ensuring dimensional accuracy and appearance quality. The use of a wedge and slider combination mechanism solves the problem of irregularly shaped inserts collapsing under conventional working methods.
