Abstract
Description
Technical Field
[0001] This utility model relates to a shaping mechanism, specifically a shaping mechanism for bimetallic bushings, and belongs to the field of bimetallic bushing shaping technology. Background Technology
[0002] Bimetallic bearings are a type of oil-free lubricated bearing. This product uses a high-quality low-carbon steel backing as the base material, with a lead-tin bronze alloy sintered on the surface. It is manufactured by repeatedly sintering at high temperatures and undergoing dense rolling to form a bimetallic strip integrating copper and steel. It is suitable for various applications such as bushings and thrust washers that withstand medium-speed, high-impact loads. A bimetallic bushing is a sliding bearing component made of two different metal materials.
[0003] However, when using a rounding machine to shape the inner wall of a bushing, the conical surface of the central sliding column drives multiple expansion blocks to press the inner wall of the bushing, so that the deformed parts of the inner wall of the bushing are repaired. During the process, the operator also needs to rotate and adjust the position of the bushing, which is cumbersome and does not make it easy to improve the shaping efficiency of the bushing. Utility Model Content
[0004] The purpose of this utility model is to provide a shaping mechanism for a bimetallic bushing in order to solve the above problems. The clamping plate on the hydraulic rod drives the slide to abut against the side wall of the bushing. When the drive mechanism drives the locking block to rotate, the clamping plate drives the fixed bushing to rotate. In this way, while reducing the need for operators to manually rotate the bushing position, the rounding mechanism can also round various parts of the inner wall of the bushing.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a shaping mechanism for a bimetallic bushing, comprising a body, a rounding mechanism mounted on the body, a driving mechanism fixed on the rounding mechanism, a through groove at the top of the driving mechanism, a plurality of clamping mechanisms equidistantly sliding on the through groove, the clamping mechanism comprising a support block and a locking block, a plurality of locking blocks slidably mounted on the through groove, a support block fixedly connected to the locking block, a hydraulic rod fixedly mounted inside the support block, a sliding rod fixedly connected to the telescopic end of the hydraulic rod, and a clamping plate fixedly mounted on the sliding rod.
[0006] Preferably, the slide rod and the support block are slidably connected, and the clamping plate is configured with an arc surface structure.
[0007] Preferably, the circular mechanism includes a base and a central sliding column. The base is fixedly connected to the top of the machine body, and the central sliding column is slidably installed inside the base. The side wall of the central sliding column abuts against several expansion blocks.
[0008] Preferably, the central sliding column is located at the center of the base, and several expansion blocks are arranged in a ring at equal intervals, with the sidewalls of the expansion blocks near the clamping plate having an arc-shaped structure.
[0009] Preferably, the drive mechanism includes mounting blocks and support rods. Several mounting blocks are fixedly connected to the top of the base. Support rods are fixedly connected to the mounting blocks. Card holders are fixedly connected to the support rods. A motor is fixedly mounted on the top of the card holders. A rotating shaft is fixedly connected to the output end of the motor via a coupling. A gear is fixedly mounted on the rotating shaft. A gear ring meshes with the gear. The gear ring is fixedly connected to the card blocks.
[0010] Preferably, the mounting blocks and support rods are arranged in a ring at equal intervals, with the support rods located at the end of the card seat opposite to the through groove.
[0011] Preferably, the central sliding column and the expansion block are both located at the center of the card seat, and several of the support blocks move in a circular motion along the top of the card seat.
[0012] Preferably, the diameter of the gear ring is larger than the diameter of the gear, and both the gear ring and the gear are rotatably connected to the card holder.
[0013] Preferably, the rotating shaft is rotatably connected to the card holder, and the height of the through groove is equal to the height of the card block.
[0014] The beneficial effects of this utility model are as follows: The operator places the bimetallic bushing on the side wall of the rounding mechanism, and then turns on the control switch of the hydraulic rod. The hydraulic rod drives the slide rod fixed at its telescopic end to slide inside the support block. The slide rod drives the clamp plate fixed at the top to move closer to the bushing. When multiple arc-shaped clamp plates simultaneously abut against the side wall of the bushing, the bushing can be limited. When the drive mechanism drives multiple clamping blocks to rotate, the clamp plates can drive the bushing to rotate, so that all parts of the inner wall of the bushing can be shaped by the rounding mechanism, which also reduces the tedious steps of manually rotating the bushing by the operator.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] Please see Figure 1-6 As shown, a forming mechanism for a bimetallic bushing includes a body 1, on which a rounding mechanism 2 is mounted. A driving mechanism 4 is fixed to the rounding mechanism 2. The top of the driving mechanism 4 is provided with a through groove 5. A plurality of clamping mechanisms 3 are equidistantly slidably arranged in the through groove 5. Each clamping mechanism 3 includes a support block 303 and a locking block 305. A plurality of locking blocks 305 are slidably mounted in the through groove 5. The support block 303 is fixedly connected to the locking block 305. When the locking block 305 moves in the through groove 5, it can drive the support block 303 to move. The support block 303 rotates; a hydraulic rod 304 is fixedly installed inside the support block 303, and a sliding rod 302 is fixedly connected to the telescopic end of the hydraulic rod 304. The sliding rod 302 is slidably connected to the support block 303, and a clamping plate 301 is fixedly installed on the sliding rod 302. The clamping plate 301 is arranged with an arc surface structure. The hydraulic rod 304 drives the sliding rod 302 to slide inside the support block 303, so that the sliding rod 302 drives the clamping plate 301 to slide towards the side wall of the bushing, thereby fixing the bushing with multiple clamping plates 301.
[0024] As a technical optimization of this utility model, the circular mechanism 2 includes a base 201 and a central sliding column 202. The top of the body 1 is fixedly connected to the base 201, and the central sliding column 202 is slidably installed inside the base 201. The central sliding column 202 is rigidly connected to the piston rod of the hydraulic cylinder provided inside the base 201. The hydraulic oil pushes the piston rod to move axially, which can realize the extension and retraction of the central sliding column 202. The side wall of the central sliding column 202 abuts against several expansion blocks 203. When the bushing is located on the base 201, the central sliding column 202 and several expansion blocks 203 can penetrate its inner wall. Several expansion blocks 203 are arranged in a ring at equal intervals. The side wall of the central sliding column 202 is conical. Multiple expansion blocks 203 are arranged around the conical surface, and the inner side surface is in contact with the conical surface. The conical surface of the central sliding column 202 pushes the expansion blocks 203 to move radially outward along the inclined surface, pressing the inner wall of the bushing, so that the expansion blocks 203 can be circularly aligned with the inner wall of the bushing.
[0025] As a technical optimization of this utility model, the driving mechanism 4 includes a mounting block 401 and a support rod 402. A plurality of mounting blocks 401 are fixedly connected to the top of the base 201. Support rods 402 are fixedly connected to the mounting blocks 401. A retaining seat 403 is fixedly connected to the support rod 402. A motor 404 is fixedly mounted on the top of the retaining seat 403. A rotating shaft 407 is fixedly connected to the output end of the motor 404 via a coupling. When the motor 404 is started, the rotating shaft 407 rotates within the retaining seat 401. 3. Internal rotation; the rotating shaft 407 is rotatably connected to the card holder 403. A gear 406 is fixedly installed on the rotating shaft 407. A gear ring 405 meshes with the gear 406. Both the gear ring 405 and the gear 406 are rotatably connected to the card holder 403. The rotating shaft 407 drives the gear 406 fixed on the side wall to rotate, so that the gear ring 405 can drive several card blocks 305 fixed at the top to rotate, thereby causing the card blocks 305 to drive the clamping plate 301 to rotate, so that the clamping plate 301 can drive the bushing to rotate.
[0026] In use, the operator places the bimetallic bushing in the center of the holder 403, with its bottom end contacting the top of the base 201. When the bushing is on the base 201, the central sliding column 202 and several expansion blocks 203 can penetrate its inner wall. The central sliding column 202 is rigidly connected to the piston rod of the hydraulic cylinder installed in the base 201. Hydraulic oil pushes the piston rod to move axially, which can realize the extension and retraction of the central sliding column 202. The side wall of the central sliding column 202 is conical, and multiple expansion blocks 203 are arranged around the conical surface, with their inner surfaces fitting against the conical surface. The conical surface of the central sliding column 202 pushes the expansion blocks 203 to move radially outward along the inclined surface, pressing the inner wall of the bushing, so that the expansion blocks 203 can be made round against the inner wall of the bushing. When adjusting the machined part of the inner wall of the bushing, the control switch of the hydraulic rod 304 can be turned on, and the hydraulic rod 304 drives its extension end to be fixed. The fixed slide rod 302 slides within the support block 303. The slide rod 302 drives the top fixed clamping plate 301 to move closer to the bushing. When multiple arc-shaped clamping plates 301 simultaneously abut against the side wall of the bushing, the bushing can be limited. Then, the switch of the motor 404 fixed at the top of the card seat 403 is turned on. The rotating shaft 407 drives the gear 406 inside the card seat 403. The gear 406 meshes with the gear ring 405. The rotation of the gear 406 can drive the gear ring 405 to rotate. Multiple clamping blocks 305 are fixed at equal intervals on the top of the gear ring 405. When the gear ring 405 rotates along the inner wall of the card seat 403, it can cause the clamping blocks 305 to drive the support block 303 to rotate, thereby causing the clamping plate 301 on the slide rod 302 to drive the bushing to rotate. This allows various parts of the inner wall of the bushing to be shaped by the expansion block 203, and also reduces the tedious steps of manually rotating the bushing by the operator.
