Description

Technical Field

[0001] This utility model relates to the field of bushing assembly, specifically to a bushing pressing and assembly equipment. Background Technology

[0002] Shock absorber bushings are the core buffer components of a car's suspension system. They are mainly used to absorb vibrations and reduce metal-to-metal friction. Their condition directly affects driving safety and comfort. During assembly, shock absorber bushings need to be pressed into the shock absorber rings. In addition, a counter-pressure operation is required to push the over-pressurized part back into place, thus completing the entire pressing process.

[0003] Patent CN103737287A discloses a multi-purpose shock absorber bushing press-fitting machine, including a base. Four support rods are arranged on the bottom surface of the base. A fixing plate is arranged in the middle of the four support rods. A positioning seat is arranged on the fixing plate, and a positioning block is embedded in the positioning seat. A top plate is arranged on the top of the four support rods. A push cylinder passes through the middle of the top plate. A push block is arranged below the push cylinder. A start button and a stop button are arranged in sequence on the right side of the base.

[0004] This multi-purpose shock absorber bushing press cannot perform the reverse push operation of the shock absorber bushing. The main body of the shock absorber needs to be flipped over manually before it can be reverse pressed, which is a rather cumbersome operation. Utility Model Content

[0005] The purpose of this invention is to provide a bushing pressing and assembly device that can automatically flip the bushing after pressing it in order to perform reverse pressing.

[0006] To achieve the above objectives, this utility model provides a bushing pressing and assembly device, including a tooling table and a horizontal rotating mechanism installed at the rear end of the tooling table, and a positioning table installed at the front end of the horizontal rotating mechanism. The positioning table has a lifting ring limiting groove in the middle, and bushing guide holes are provided at the upper and lower ends of the lifting ring limiting groove. The positioning table has a lifting ring guide slot at the front end, and shock absorber body clearance openings are provided at the upper and lower ends of the lifting ring guide slot. A portal frame is provided on the tooling table at the positioning table, and an electric cylinder is installed on the portal frame. A pressure head coaxial with the bushing guide hole is provided at the bottom of the cylinder shaft of the electric cylinder. A shock absorber body support block is provided at the front end of the tooling table.

[0007] Preferably, the horizontal rotation mechanism includes a fixed base with a through groove on the fixed base. A rotating shaft is disposed in the groove, and a gear is sleeved on the rotating shaft. A rack meshes with the bottom of the gear. A cylinder is mounted on the tooling table via a mounting seat. The shaft of the cylinder is connected to and pushes the rack. The front end of the rotating shaft passes through the fixed base and is connected to the rear end of the positioning table.

[0008] Preferably, the rack has guide grooves on both sides, and the inner wall of the groove has a guide strip that slides with the guide groove. The rotating shaft and the fixed seat are connected by a bearing.

[0009] Preferably, the rear end of the positioning stage is provided with a circular support; the inner wall of the circular support is connected to the positioning stage through a support plate, and the tooling stage is provided with a support seat that provides sliding support for the circular support.

[0010] Preferably, a first guide surface is provided on both sides of the port of the lifting ring guide slot; a second guide surface is provided on the outer port of the bushing guide hole.

[0011] Preferably, the portal frame includes two symmetrically arranged columns, each column has a screw at its upper end, a top plate is fitted onto the screw, and the screw is locked in place by a nut.

[0012] Preferably, the lower end of the pressure head is provided with a frustum column and an insertion guide rod in sequence.

[0013] Preferably, the upper end of the shock absorber main support block is provided with an arc groove.

[0014] According to the above technical solution, this utility model provides a bushing pressing and assembly equipment, including a tooling table and a horizontal rotating mechanism installed at the rear end of the tooling table, and a positioning table installed at the front end of the horizontal rotating mechanism. The positioning table is provided with a lifting ring limiting groove in the middle, and bushing guide holes are provided at the upper and lower ends of the lifting ring limiting groove. The positioning table is provided with a lifting ring guide slot at the front end, and shock absorber body clearance openings are provided at the upper and lower ends of the lifting ring guide slot. A portal frame is provided on the tooling table at the positioning table, and an electric cylinder is installed on the portal frame. A pressure head coaxial with the bushing guide hole is provided at the bottom of the cylinder shaft of the electric cylinder. A shock absorber body support block is provided at the front end of the tooling table.

[0015] When using this bushing pressing and assembly equipment, one end of the shock absorber bushing lifting ring is inserted into the lifting ring limiting groove through the lifting ring guide slot, and the bushing is placed into the upper bushing guide hole. The pressing head, driven by an electric cylinder, presses down to press the bushing into the lifting ring. Since overpressure is required during bushing pressing, the positioning table is rotated 180 degrees using a horizontal rotation mechanism, and the pressing head, driven by an electric cylinder, presses down again to straighten the overpressured bushing, thus completing the bushing pressing operation. A shock absorber body support block supports the main body of the shock absorber, and a clearance opening is used to avoid the protruding rear end of the shock absorber body. This bushing pressing and assembly equipment can automatically flip the bushing after pressing for reverse pressing, making operation more convenient.

Detailed Implementation

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0024] See Figure 1-2 The bushing pressing and assembly equipment shown includes a tooling table 1 and a horizontal rotating mechanism installed at the rear end of the tooling table 1, and a positioning table 4 installed at the front end of the horizontal rotating mechanism. The positioning table 4 has a lifting ring limiting groove 5 in the middle, and bushing guide holes 6 are provided at the upper and lower ends of the lifting ring limiting groove 5. The positioning table 4 has a lifting ring guide slot 15 at the front end, and shock absorber body clearance openings 16 are provided at the upper and lower ends of the lifting ring guide slot 15. A gantry frame is provided on the tooling table 1 at the positioning table 4, and an electric cylinder 8 is installed on the gantry frame. A pressure head coaxial with the bushing guide hole 6 is provided at the bottom of the cylinder shaft 18 of the electric cylinder 8. A shock absorber body support block 2 is provided at the front end of the tooling table 1.

[0025] Through the implementation of the above technical solution, when using the bushing pressing and assembly equipment, one end of the shock absorber bushing lifting ring is inserted into the lifting ring limiting groove 5 through the lifting ring guide slot 15, and the bushing is placed into the upper bushing guide hole 6. The pressing head is driven by the electric cylinder 8 to press down and press the bushing into the lifting ring. Since the bushing pressing requires over-pressing, the positioning table 4 is rotated 180 degrees by the horizontal rotation mechanism, and then the pressing head is driven by the electric cylinder 8 to press down and straighten the over-pressed bushing, thereby realizing the bushing pressing operation. The shock absorber body support block 2 is used to support the shock absorber body, and the shock absorber body avoidance opening 16 is used to avoid the protruding position at the rear end of the shock absorber body. The bushing pressing and assembly equipment can automatically flip after pressing the bushing for reverse pressing, eliminating the need for manual flipping and making the operation more convenient. Since the shock absorber body is not equipped with a limiting mechanism, simple manual support is required during the flipping process, and the lifting ring is pushed back into place during the reverse pressing.
