Description

Technical Field

[0001] This utility model relates to the field of aluminum bushing adhesive removal technology, specifically to an adhesive removal device for automotive aluminum bushing production. Background Technology

[0002] Automotive bushings are composite material components installed on parts such as the car chassis, suspension system, and engine mounts. They are mainly used to reduce vibration, noise, and impact generated during vehicle operation, while providing stable support and precise positioning for related components.

[0003] When automotive leaf springs are subjected to compressive loads, installing leaf spring bushings can effectively buffer and dampen shocks; generally, bushings with an alloy and rubber composite structure are selected.

[0004] In the production of automotive aluminum bushings, a rubber layer needs to be added to the surface of the aluminum body. The rubber material is heated and then extruded. However, if the extruded rubber is not cooled down in time, it is easy to generate large protrusions due to stretching during the molding process. These protrusions will lead to a lot of waste.

[0005] Patent CN205689675U discloses an automotive shock absorber bushing. By providing an inner skeleton and an outer skeleton on both sides of the rubber body, the inner skeleton and the outer skeleton restrict the lateral expansion and contraction of the rubber body on the one hand, and restrict the tendency of the rubber body to detach towards the longitudinal ends on the other hand. By providing a rubber coating layer on the sides of the inner skeleton and the outer skeleton, it is beneficial to the adhesion between the rubber body and the metal skeleton, and improves the connection reliability after vulcanization.

[0006] However, the automotive bushing in this patent has the following drawbacks: the vulcanized rubber bushing will produce large protrusions due to stretching during the molding process, and the resulting rubber edges still rely on manual cleaning, resulting in low work efficiency and unsatisfactory cleaning effect, which is difficult to meet production needs. Utility Model Content

[0007] To address the technical problems in existing technologies where the cleaning of rubber edges on bushings mainly relies on manual labor, which is not only time-consuming and labor-intensive, but also inefficient and difficult to guarantee, failing to meet the high standards of modern production, this utility model provides a rubber edge removal device for automotive aluminum bushing production.

[0008] The objective of this utility model can be achieved through the following technical solutions:

[0009] A device for removing adhesive edges in the production of automotive aluminum bushings includes a support plate and a first rotating shaft mounted on the support plate; one side of the support plate is fixedly connected to the first rotating shaft and a second rotating shaft, the other end of the first rotating shaft is rotatably connected to a first connecting rod, the other end of the second rotating shaft is rotatably connected to a second connecting rod, and the support plate is fixedly connected to a first gear, the bottom of which is meshed with a second gear.

[0010] Furthermore, a first fixed shaft is fixedly installed on both the first gear and the second gear, and a first sliding groove that cooperates with the first fixed shaft is provided in the middle of the first connecting rod and the second connecting rod.

[0011] Furthermore, a fixed seat is fixedly installed on the support plate, and a third sliding groove is provided inside the fixed seat, with a matching sliding block provided on the third sliding groove.

[0012] Furthermore, the sliding block is convex in shape, and a knife handle is fixedly mounted on the upper surface of the sliding block. A blade is provided at the bottom of the knife handle; a second fixing block is fixedly connected to the upper surface of the knife handle.

[0013] Furthermore, the other end of the first connecting rod is provided with a second sliding groove, and a second fixing block is fitted inside the second sliding groove.

[0014] Furthermore, the support plate has a groove on the side near the support base, and the groove is rectangular in shape; the first connecting rod and the second connecting rod are symmetrically arranged with respect to the midpoint of the short side of the groove.

[0015] Furthermore, the first fixed block on the first gear slides within the first sliding groove, and the first connecting rod rotates at 0-30 degrees around the first rotating shaft; the first fixed block on the second gear slides within the first sliding groove, and the second connecting rod rotates at 0-30 degrees around the second rotating shaft.

[0016] Furthermore, a fourth rotating shaft is rotatably connected to the inner wall of the support plate at the slot position. The fourth rotating shaft is provided with a first synchronous toothed belt. The other end of the first synchronous toothed belt is connected to a third rotating shaft. A second motor is provided at one end of the third rotating shaft. Both ends of the first synchronous toothed belt are provided with synchronous toothed belts. A support column is provided at the bottom of the third rotating shaft.

[0017] Furthermore, the first synchronous toothed belt is located on one side near the first motor support plate, and the other side of the support plate is provided with a second synchronous toothed belt.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model involves placing the bushings to be cut sequentially onto a first synchronous toothed belt, with one end of the bushing facing the slot. A second motor is activated to convey the bushings. The first motor then drives a first gear to rotate, which meshes with a second gear. The first and second gears cause a first fixed block to slide within a first sliding groove. Because the first fixed block moves in a circular motion, it simultaneously causes a first connecting rod to rotate at an angle around a first rotating axis, and a second connecting rod to rotate at an angle around a second rotating axis, simultaneously causing a second fixed block to slide within a second sliding groove. The second fixed block then causes a cutter handle to move up and down within a third sliding groove. The first and second connecting rods move in a scissor-like motion. When the bushing is conveyed to the slot, a corresponding cutter cuts it, removing the adhesive edge. The cut bushing is then conveyed onto the second synchronous toothed belt, improving the efficiency of removing the adhesive edge and achieving automated production. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figure 1 As shown, a de-adhesive edge removal device for automotive aluminum bushing production includes a support plate 1 and a first rotating shaft 5 mounted on the support plate 1; one end of the first rotating shaft 5 is fixedly connected to one side of the support plate 1, and a first motor 101 is provided on the other side of the support plate 1. The output end of the first motor 101 passes through the support plate 1 and is fixedly connected to a first gear 2. A first fixed shaft 201 is fixedly mounted on the first gear 2.

[0029] Please see Figure 2 As shown, the other end of the first rotating shaft 5 is rotatably connected to one end of the first connecting rod 4. The middle part of the first connecting rod 4 is provided with a first sliding groove 202 that cooperates with the first fixed shaft 201. The other end of the first connecting rod 4 is provided with a second sliding groove 204. A second fixed block 203 is provided in the second sliding groove 204.

[0030] A fixed seat 8 is fixedly installed on the support plate 1 opposite to the first fixed shaft 201. The fixed seat 8 has a third sliding groove 801 inside. A matching sliding block 802 is provided on the third sliding groove 801. The sliding block 802 is convex in shape. A knife handle 803 is fixedly installed on the upper surface of the sliding block 802. A blade is provided at the bottom of the knife handle 803. The second fixed block 203 is fixedly connected to the upper surface of the knife handle 803.

[0031] The bottom of the first gear 2 is engaged with the second gear 3. The second gear 3 is also provided with a first fixing block. The first fixing block is slidably connected to the second connecting rod 6. One end of the second connecting rod 6 is rotatably connected to one end of the second rotating shaft 7. The other end of the second rotating shaft 7 is fixedly connected to the support plate 1. The other end of the second connecting rod 6 is also provided with a second fixing block 203. The bottom of the second fixing block 203 is fixedly connected to the knife handle 803. A blade is provided on the top of the knife handle 803 on the side corresponding to the second connecting rod 6. That is, the two blades are arranged opposite each other.

[0032] The support plate 1 has a slot 102 on the side near the support base. The slot 102 is rectangular. When the first connecting rod 4 and the second connecting rod 6 rotate to the position of the slot 102, the opposing cutters can cut the bushing inside the slot 102. The first connecting rod 4 and the second connecting rod 6 are symmetrically arranged about the midpoint of the short side of the slot 102.

[0033] The first motor 101 drives the first gear 2 to rotate, and the first gear 2 meshes with the second gear 3 to rotate. The first gear 2 and the second gear 3 drive the first fixed block to slide in the first sliding groove 202. Since the first fixed block is in a circular motion, it also drives the first connecting rod 4 to rotate at an angle with the first rotating shaft 5 as the center, and the second connecting rod 6 to rotate at an angle with the second rotating shaft 7 as the center. At the same time, it drives the second fixed block 203 to slide in the second sliding groove 204. The second fixed block 203 drives the knife handle 803 to move up and down in the third sliding groove 801. The first connecting rod 4 and the second connecting rod 6 move in a scissor shape.

[0034] Please see Figure 4 As shown, as the first fixed block on the first gear 2 slides in the first sliding groove 202, the first connecting rod 4 rotates at 0-30 degrees around the first rotating shaft 5.

[0035] As the first fixed block on the second gear 3 slides within the first sliding groove 202, the second connecting rod 6 rotates at 0-30 degrees around the second rotating shaft 7.

[0036] Please see Figure 3 As shown, a fourth rotating shaft 10 is rotatably connected to the inner wall of the support plate 1 at the slot 102 position. A first synchronous toothed belt 902 is provided on the fourth rotating shaft 10. The other end of the first synchronous toothed belt 902 is connected to a third rotating shaft 901. A second motor 9 is provided at one end of the third rotating shaft 901. Both ends of the first synchronous toothed belt 902 are provided with synchronous pulleys 904. A support column 903 is provided at the bottom of the third rotating shaft 901.

[0037] The first synchronous toothed belt 902 is located on one side near the support plate 1 of the first motor 101. The other side of the support plate 1 is provided with a second synchronous toothed belt 1102. One end of the second synchronous toothed belt 1102 is connected to the fifth rotating shaft 1101, one end of the fifth rotating shaft 1101 is connected to the third motor 11, and the other end of the second synchronous toothed belt 1102 is connected to the sixth rotating shaft 12. Support blocks are provided at both ends of the sixth rotating shaft 12, and the support blocks are connected to the side of the support plate 1. In order to make the bushing more fixed on the first synchronous toothed belt 902, clamps (not shown in this figure) can be provided on both sides of the upper surface of the first synchronous toothed belt 902. The clamps are matched with the bushing, and the length of the clamps is less than the length of the bushing. The distance between the first synchronous toothed belt 902 and the second synchronous toothed belt 1102 is less than the length of the bushing.

[0038] To facilitate the collection of waste materials after cutting, a collection bucket can be installed at the bottom of the cutter (not shown in this figure);

[0039] By sequentially placing the bushings onto the first synchronous toothed belt 902, turning on the second motor 9 to convey the bushings, and then cutting the ends of the bushings with upper and lower cutters, the cut bushings are then conveyed onto the second synchronous toothed belt 1102.

[0040] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below:

[0041] First, the bushings are placed sequentially on the first synchronous toothed belt 902. The second motor 9 is turned on to convey the bushings. Then, the first motor 101 drives the first gear 2 to rotate, which meshes with the second gear 3. The first gear 2 and the second gear 3 drive the first fixed block to slide within the first sliding groove 202. As the first fixed block moves in a circular motion, it simultaneously drives the first connecting rod 4 to rotate at an angle around the first rotating shaft 5, and the second connecting rod 6 to rotate at an angle around the second rotating shaft 7. Simultaneously, it drives the second fixed block 203 to slide within the second sliding groove 204. The second fixed block 203 drives the knife handle 803 to move up and down within the third sliding groove 801. The first connecting rod 4 and the second connecting rod 6 move in a scissor-like motion. When the bushing is conveyed to the groove opening 102, the oppositely positioned cutter cuts it, removing the rubber edge of the bushing. The cut bushing is then conveyed onto the second synchronous toothed belt 1102.
