Description

Technical Field

[0001] This utility model relates to the field of pin sleeve production technology, specifically to an automated pin sleeve production line. Background Technology

[0002] The materials used for track pin bushings of engineering excavators are generally 40CrB and 20CrMnTi. These materials have uniform chemical composition, dense and defect-free structure, good hardness and plasticity, and high hardness and wear resistance on the surface after heat treatment. In order to reduce material loss and speed up forging efficiency in the production of pin bushings, the existing technology generally adopts stamping to produce pin bushings. After that, the pin bushings are polished and cleaned before entering the subsequent processes.

[0003] Currently, after grinding the pin sleeves, in order to avoid leaving impurities on the inner wall of the pin sleeves, multiple pin sleeves are placed together in a cleaning tank to clean the impurities on the inner wall of the pin sleeves. However, this method involves many pin sleeves together, which makes it impossible to clean all the impurities on the inner wall of the pin sleeves. Furthermore, the cleaning method is only to clean by the flow of water, which cannot effectively clean the impurities adhering to the inner wall of the pin sleeves, affecting the subsequent use of the pin sleeves. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automated pin sleeve production line.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated pin sleeve production line includes:

[0007] A water storage tank and a pin sleeve body, wherein the water storage tank is provided with a conveying mechanism for conveying the pin sleeve body;

[0008] A cleaning mechanism includes a first U-shaped plate fixedly connected to the upper end of a water storage tank. Two cylinders are fixedly connected to the upper end of the first U-shaped plate, and a second U-shaped plate is fixedly connected to the movable end of each of the two cylinders. A vertical rod is rotatably connected to the lower end of the second U-shaped plate, and multiple cleaning strips are fixedly connected to the side wall of the vertical rod. A threaded cylinder is fixedly connected to the inner side wall of the first U-shaped plate via a bracket. The upper end of the vertical rod passes through the lower end of the second U-shaped plate and is fixedly connected to a bolt. The side wall of the bolt is threadedly connected to the inner wall of the threaded cylinder. A water inlet pipe is fixedly connected to the lower end of the second U-shaped plate.

[0009] Preferably, the conveying mechanism includes a first rod and a second rod rotatably connected to the inner wall of the water storage tank. Two first wheels are fixedly connected to the side wall of the first rod, and two second wheels are fixedly connected to the side wall of the second rod. A conveyor belt is fixedly connected between the first wheel and the second wheel on the same side. Multiple corresponding connecting plates are fixedly connected to the side walls of the two conveyor belts. A conveying cylinder is fixedly connected between two adjacent connecting plates on the two conveyor belts. A through groove is opened at the bottom of the conveying cylinder, and the pin sleeve body is located inside the conveying cylinder.

[0010] Preferably, two sliding rods are symmetrically slidably connected to the inner wall of the conveying cylinder, and clamping plates are fixedly connected to the side walls of the two sliding rods that are close to each other. The side walls of the clamping plates close to the sliding rods are elastically connected to the inner wall of the conveying cylinder through multiple springs.

[0011] Preferably, a motor is fixedly connected to the side wall of the water storage tank, and the movable end of the motor is fixedly connected to one end of the second rod.

[0012] Preferably, a drain pipe is fixedly connected to the lower inner wall of the water storage tank near the second rod, and a manual regulating valve is installed on the drain pipe.

[0013] This utility model has the following beneficial effects:

[0014] 1. A cleaning mechanism is installed in which the vertical rod and multiple cleaning strips move up and down and rotate into the pin sleeve body. Water flowing from the inlet pipe enters the pin sleeve body to effectively clean the impurities adhering to the inner wall of the pin sleeve body. This avoids the problem in the existing technology of cleaning many pin sleeves together, which cannot clean all the impurities on the inner wall of the pin sleeves. Furthermore, the cleaning method is only through the flow of water, which cannot effectively clean the impurities adhering to the inner wall of the pin sleeve, thus affecting the subsequent use of the pin sleeve.

[0015] 2. Two clamping plates are set up. After the pin sleeve body is placed in the conveying cylinder, the two clamping plates move closer to each other under the elastic force of multiple springs, so that the two clamping plates can clamp the pin sleeve body and prevent it from shaking during movement.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-6 An automated pin sleeve production line includes a water storage tank 1 and a pin sleeve body 10. The water storage tank 1 is equipped with a conveying mechanism for conveying the pin sleeve body 10.

[0025] The conveying mechanism includes a first rod 2 and a second rod 4 rotatably connected to the inner wall of the water storage tank 1. Two first wheels 3 are fixedly connected to the side wall of the first rod 2, and two second wheels 5 are fixedly connected to the side wall of the second rod 4. A conveyor belt 6 is fixedly connected between the first wheel 3 and the second wheel 5 on the same side. Multiple corresponding connecting plates 7 are fixedly connected to the side walls of the two conveyor belts 6. A conveying cylinder 8 is fixedly connected between two adjacent connecting plates 7 on the two conveyor belts 6. A through groove 9 is opened at the bottom of the conveying cylinder 8, and the pin sleeve body 10 is located inside the conveying cylinder 8.

[0026] A motor 24 is fixedly connected to the side wall of the water storage tank 1, and the movable end of the motor 24 is fixedly connected to one end of the second rod 4.

[0027] A drain pipe 23 is fixedly connected to the lower inner wall of the water storage tank 1 near the second rod 4. A manual regulating valve is installed on the drain pipe 23 to facilitate the drainage of water from the water storage tank 1.

[0028] During the forward rotation of motor 24, it drives the first rod 2 and the two first wheels 3 to rotate, which in turn drives the second rod 4 and the two second wheels 5 to rotate via the two conveyor belts 6, so that the two conveyor belts 6 move away from the drain pipe 23, thereby driving multiple conveyor cylinders 8 to move away from the drain pipe 23, and thus moving multiple pin sleeve bodies 10.

[0029] Two sliding rods 11 are symmetrically slidably connected to the inner wall of the conveying cylinder 8. Clamping plates 12 are fixedly connected to the side walls of the two sliding rods 11 that are close to each other. The side walls of the clamping plates 12 that are close to the sliding rods 11 are elastically connected to the inner wall of the conveying cylinder 8 through multiple springs 13.

[0030] After the pin sleeve body 10 is placed inside the conveying cylinder 8, the lower end of the pin sleeve body 10 is in contact with the bottom of the conveying cylinder 8, and the center of the pin sleeve body 10 is directly opposite the through groove 9 (the inner diameter of the pin sleeve body 10 is smaller than the diameter of the through groove 9, and the outer diameter of the pin sleeve body 10 is larger than the diameter of the through groove 9). At this time, the two clamping plates 12 approach each other under the elastic force of multiple springs 13, so that the two clamping plates 12 can clamp the pin sleeve body 10 tightly and prevent it from shaking during movement.

[0031] The cleaning mechanism includes a first recessed plate 14 fixedly connected to the upper end of the water storage tank 1. Two cylinders 15 are fixedly connected to the upper end of the first recessed plate 14. A second recessed plate 16 is fixedly connected to the movable end of each cylinder 15. A vertical rod 17 is rotatably connected to the lower end of the second recessed plate 16. Multiple cleaning strips 18 are fixedly connected to the side wall of the vertical rod 17. A threaded cylinder 21 (e.g., ...) is fixedly connected to the inner side wall of the first recessed plate 14 via a bracket 20. Figure 2 and Figure 6 As shown), the upper end of the vertical rod 17 passes through the lower end of the second U-shaped plate 16 and is fixedly connected to the bolt rod 22. The side wall of the bolt rod 22 is threadedly connected to the inner wall of the threaded cylinder 21. The lower end of the second U-shaped plate 16 is fixedly connected to the water inlet pipe 19.

[0032] It should be noted that the water inlet pipe 19 is connected to an external water pump, and water can be pumped to the pin sleeve body 10 for cleaning through the water inlet pipe 19.

[0033] When the pin sleeve body 10 moves to a position directly below the multiple cleaning strips 18, the motor 24 stops rotating, and the position of the pin sleeve body 10 remains unchanged. Then, the two cylinders 15 are adjusted to intermittently extend and retract, driving the second U-shaped plate 16 to move up and down, so that the vertical rod 17 and the multiple cleaning strips 18 move up and down inside the pin sleeve body 10. The vertical rod 17 moves up and down, driving the bolt 22 to move up and down. At this time, the position of the threaded cylinder 21 is fixed. Under the action of the threaded cylinder 21, the bolt 22 moves up and down and rotates, driving the vertical rod 17 and the multiple cleaning strips 18 to move up and down and rotate. Water flowing out from the water inlet pipe 19 enters the pin sleeve body 10, effectively cleaning the impurities adhering to the inner wall of the pin sleeve body 10. This avoids the problem of cleaning many pin sleeves together in the prior art, which cannot clean all the impurities on the inner wall of the pin sleeves. Furthermore, the cleaning method is only cleaning by the flow of water, which cannot effectively clean the impurities adhering to the inner wall of the pin sleeves, affecting the subsequent use of the pin sleeves.

[0034] After cleaning the inner wall of the pin sleeve body 10, adjust the two cylinders 15 to retract to their original positions so that the multiple cleaning strips 18 are located directly above the pin sleeve body 10. Then, continue to drive the motor 24 to rotate in the forward direction to transport the pin sleeve body 10. After that, the staff can take the cleaned pin sleeve body 10 out of the conveying cylinder 8.

[0035] When cleaning the inner wall of the pin sleeve body 10, the drive motor 24 first rotates in the forward direction, driving the first rod 2 and the two first wheels 3 to rotate, and then the two conveyor belts 6 drive the second rod 4 and the two second wheels 5 to rotate, so that the two conveyor belts 6 move away from the drain pipe 23, and then drive the multiple conveyor cylinders 8 to move away from the drain pipe 23. Then the pin sleeve body 10 is placed in the moving conveyor cylinder 8, so that the multiple pin sleeve bodies 10 can move.

[0036] After the pin sleeve body 10 is placed in the conveying cylinder 8, the two clamping plates 12 approach each other under the elastic force of multiple springs 13, so that the two clamping plates 12 can clamp the pin sleeve body 10 and prevent it from shaking during movement.

[0037] When the pin sleeve body 10 moves to a position directly below the multiple cleaning strips 18, the motor 24 stops rotating, and the position of the pin sleeve body 10 remains unchanged. Then, the two cylinders 15 are adjusted to extend and retract intermittently, driving the second U-shaped plate 16 to move up and down, so that the vertical rod 17 and the multiple cleaning strips 18 move up and down inside the pin sleeve body 10. The vertical rod 17 moves up and down, driving the auger rod 22 to move up and down. At this time, the position of the threaded cylinder 21 is fixed. Under the action of the threaded cylinder 21, the auger rod 22 moves up and down and rotates, driving the vertical rod 17 and the multiple cleaning strips 18 to move up and down and rotate. Water flowing out from the water inlet pipe 19 enters the pin sleeve body 10, effectively cleaning the impurities adhering to the inner wall of the pin sleeve body 10.

[0038] After cleaning the inner wall of the pin sleeve body 10, adjust the two cylinders 15 to retract to their original positions so that the multiple cleaning strips 18 are located directly above the pin sleeve body 10. Then, continue to drive the motor 24 to rotate in the forward direction to transport the pin sleeve body 10 away from the drain pipe 23. Then, the staff can take the cleaned pin sleeve body 10 out of the conveying cylinder 8.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
