Description

Technical Field

[0001] The utility model relates to the technical field of bushing grinding devices, in particular to a double-metal rolled bushing weld grinding device. Background Technique

[0002] The double-metal rolled bushing is a high-performance sliding bearing, mainly composed of two different metal materials, combining the excellent characteristics of the two metals and the performance of solid lubricants. Its structural features include a double-metal matrix and solid lubricants. The double-metal matrix provides sufficient strength and hardness to withstand external loads; while the solid lubricants are embedded in the metal matrix to reduce friction and wear. This bearing is formed by a rolling process and has better sealing performance and structural integrity.

[0003] The working principle of the double-metal rolled bushing is that during the movement of the bearing, the solid lubricants are gradually released to form a lubricating film, reducing the direct contact between metals, thereby reducing friction and wear. Its application fields are extensive, including heavy machinery, the automotive industry, industrial equipment, etc., and it can provide good friction performance, reduce wear and extend service life.

[0004] During the welding process of the double-metal rolled bushing, many dirt, oxides, rust and other bad substances may adhere to the metal surface. These substances will affect the quality of the welded joint, reduce the strength and quality of the welding, and may even cause irreparable damage. Therefore, it is necessary to grind and remove these bad substances. After grinding, the metal surface is smoother, which is beneficial to making the joint more firm during welding and avoiding quality problems such as incomplete welds and weld cracks.

[0005] However, at present, when some bushing grinding devices are working, they need to clamp and fix the bushing. Generally, two groups of arc-shaped clamping blocks or a three-jaw chuck are used to clamp and fix it. When only clamping and fixing the outside of bushings of different models through arc-shaped clamping blocks or a three-jaw chuck, it is not flexible and stable enough, and it will affect the grinding effect when grinding the weld on the bushing body. Content of the Utility Model

[0006] Based on this, the purpose of the utility model is to provide a double-metal rolled bushing weld grinding device to solve the technical problem that when some current bushing grinding devices are working, they need to clamp and fix the bushing. Generally, two groups of arc-shaped clamping blocks or a three-jaw chuck are used to clamp and fix it. When only clamping and fixing the outside of bushings of different models through arc-shaped clamping blocks or a three-jaw chuck, it is not flexible and stable enough, and it will affect the grinding effect when grinding the weld on the bushing body.

[0007] To achieve the above object, the present utility model provides the following technical solution: A bimetallic rolled bushing weld grinding device, comprising a workbench, a grinding structure is arranged on the top of the workbench, a support block is fixedly connected to the top of the workbench, a first motor is fixedly connected to the inner side of the support block, a driving disc is fixedly connected to the output end of the first motor, a three-jaw chuck is fixedly connected to the inner side of the driving disc, multiple groups of jaws are arranged on the three-jaw chuck, a bushing body is snap-connected to the inner sides of the multiple groups of jaws, a fixed block is fixedly connected to one side of the three-jaw chuck, a first rack, a second rack and a third rack are slidably connected in the fixed block, bumps are fixedly connected to the ends of the first rack, the second rack and the third rack, and the bumps are all in contact with the inner wall of the bushing body. A first gear, a second gear and a third gear for cooperating with the first rack, the second rack and the third rack are arranged in the fixed block, and a transmission structure for cooperating with the first gear, the second gear and the third gear is rotatably connected to one side of the three-jaw chuck.

[0008] By adopting the above technical solution, during use, first, the bushing body is fixed on the three-jaw chuck through the three-jaw chuck and the jaws. Secondly, the first gear, the second gear and the third gear are rotated in the fixed block through the transmission structure. Through the mutual cooperation between the first gear, the second gear, the third gear and the first rack, the second rack and the third rack, the first rack, the second rack and the third rack can be synchronously extended, so that the bumps are abutted against the inner wall of the bushing body. Then, through the outward expanding force of the three groups of racks and the bumps, the bushing body is limited and fixed from the inside, which can assist the three-jaw chuck to stably fix the bushing body above the workbench. Then, through the mutual cooperation between the first motor and the driving disc, the bushing body performs a rapid rotational movement. Finally, the weld on the bushing body is ground through the grinding structure. Finally, through the mutual cooperation between the first rack, the second rack, the third rack, the bumps and the three-jaw chuck, the bushing body can be clamped and fixed from the inside to the outside, which can not only make the bushing body be clamped more stably, but also play an auxiliary role in the bushing body, avoiding excessive extrusion of the three-jaw chuck and causing deformation of the bushing body, thereby improving the practicability and flexibility of the entire bimetallic rolled bushing weld grinding device.

[0009] The present utility model is further configured such that the transmission structure includes a second motor, a first gear ring, a second gear ring, a third gear ring, a transmission disc, a connecting rod, a first connecting rod, and a second connecting rod. The output end of the second motor is fixedly connected to the transmission disc through a connecting shaft. The first connecting rod is fixed between the first gear ring and the second gear ring. The second connecting rod is fixed between the second gear ring and the third gear ring. The connecting rod is fixedly connected between the second connecting rod and the transmission disc. The first gear ring, the second gear ring, and the third gear ring are located outside the fixed block and are respectively meshed with the first gear, the second gear, and the third gear. The first connecting rod is located on one side of the first rack, and the second connecting rod is located on one side of the third rack.

[0010] By adopting the above technical solution, during use, the transmission disc is driven by the second motor to perform circular motion. Through the mutual cooperation between the connecting rod and the second connecting rod, the third gear ring and the second gear ring are driven to move synchronously. Since the first connecting rod is fixedly connected between the second gear ring and the first gear ring, the three groups of gear rings can be rotated synchronously. Through the meshing state between the three groups of gear rings and the three groups of gears, when the first gear ring, the second gear ring, and the third gear ring rotate, the first gear, the second gear, and the third gear can be driven to move synchronously. And the three groups of gears are meshed with the three groups of racks. Therefore, when the three groups of gears move synchronously, the three groups of racks will be driven to move synchronously. According to actual use requirements, the rotation direction of the second motor can be controlled, so that the three groups of racks can extend and retract within the fixed block.

[0011] The present utility model is further configured such that the fixed block is provided with installation grooves for the first gear, the second gear, and the third gear to cooperate with. The first gear, the second gear, and the third gear protrude from the fixed block. The fixed block is provided with sliding grooves for the first rack, the second rack, and the third rack to cooperate with. The first rack, the second rack, and the third rack are evenly distributed within the fixed block. The included angles between the first rack, the second rack, and the third rack are equal, and the first rack, the second rack, and the third rack are not in the same horizontal line and are in a stepped shape.

[0012] By adopting the above technical solution, the first rack, the second rack and the third rack are arranged in a stepped manner. The first gear ring, the second gear ring and the third gear ring are respectively located within the first rack, the second rack and the third rack. Therefore, the first connecting rod and the second connecting rod are not on the same horizontal line either. Similar to the three groups of racks, they are in a stepped shape. At the same time, the first connecting rod is located on one side of the first rack, and the second connecting rod is located on one side of the third rack. When the second motor drives the transmission disk to perform circular motion, the first connecting rod and the second connecting rod will not be blocked by the three groups of racks. Secondly, the maximum rotation angle of the transmission disk does not exceed the included angle between the two groups of racks. Therefore, the two connecting rods and the three groups of racks will not affect each other.

[0013] The present utility model is further configured such that grooves for cooperating with the first gear ring, the second gear ring and the third gear ring are respectively formed inside the first rack, the second rack and the third rack.

[0014] By adopting the above technical solution, the provided grooves enable the first gear ring, the second gear ring and the third gear ring to flexibly perform circular motion outside the fixed block and will not be restricted in rotational motion by the first rack, the second rack and the third rack.

[0015] The present utility model is further configured such that a protective shell is provided on the top of the workbench. A sliding door is provided on one side of the protective shell. An activity groove is formed inside the protective shell and the sliding door. The sliding door is composed of multiple plates with different thicknesses. The sliding door is made of a transparent material, and a handle is fixedly connected to the sliding door.

[0016] By adopting the above technical solution, the provided protective shell can protect the grinding process, prevent dust from flying, and is also beneficial for the transfer and cleaning of powder debris in a closed environment, improving the safety of the powder debris cleaning process. Through the mutual cooperation between the sliding door composed of multiple plates with different thicknesses and the handle, it is beneficial for the feeding and discharging of the bushing.

[0017] The present utility model is further configured such that a wind guiding block is fixedly connected to the inner top of the protective shell. The wind guiding block is in a semi-circular structure and is located above the grinding structure.

[0018] By adopting the above technical solution, the provided wind guiding block can assist the grinding structure in grinding the bushing body, preventing welding slag waste from splashing everywhere and affecting the collection effect of the waste.

[0019] The present utility model is further configured such that an aggregate box is slidably connected inside the workbench. The aggregate box is located below the three-jaw chuck and the grinding structure. An activity cavity for cooperating with the second motor is provided inside the drive disk.

[0020] By adopting the above technical solution, the set aggregate box can collect and uniformly process the waste during the grinding process. Through the movable cavity in the driving disk, the second motor can be fixed in the driving disk and will not rotate simultaneously with the driving disk, enabling the second motor to normally drive the transmission disk to work.

[0021] To sum up, the main beneficial effects of the present utility model are as follows:

[0022] 1. In the present utility model, the bushing body is fixed on the three-jaw chuck through the three-jaw chuck and the jaws. Secondly, through the transmission structure, the first gear, the second gear, and the third gear rotate in the fixed block. Through the mutual cooperation between the first gear, the second gear, and the third gear and the first rack, the second rack, and the third rack, the first rack, the second rack, and the third rack can extend synchronously, making the convex block abut against the inner wall of the bushing body. Then, through the force of the three groups of racks and the convex block expanding outwards, the bushing body is limited and fixed from the inside, which can assist the three-jaw chuck to stably fix the bushing body above the workbench. Then, through the mutual cooperation between the first motor and the driving disk, the bushing body performs a rapid rotational motion. Finally, the weld on the bushing body is ground through the grinding structure. Finally, through the mutual cooperation between the first rack, the second rack, the third rack, the convex block, and the three-jaw chuck, the bushing body can be clamped and fixed from the inside to the outside, which can not only make the bushing body be clamped more stably, but also play an auxiliary role for the bushing body, avoiding excessive extrusion of the three-jaw chuck and causing deformation of the bushing body, thereby improving the practicability and flexibility of the entire bimetal coiled bushing weld grinding device;

[0023] 2. In the present utility model, the second motor drives the transmission disk to perform a circular motion. Through the mutual cooperation between the connecting rod and the second connecting rod, the third gear ring and the second gear ring are driven to move synchronously. And a first connecting rod is fixedly connected between the second gear ring and the first gear ring. Therefore, the three groups of gear rings can perform a synchronous rotational motion. Through the meshing state between the three groups of gear rings and the three groups of gears, when the first gear ring, the second gear ring, and the third gear ring rotate, the first gear, the second gear, and the third gear can be driven to move synchronously. And the three groups of gears are meshed with the three groups of racks. Therefore, when the three groups of gears move synchronously, the three groups of racks will be driven to move synchronously. According to actual use needs, the rotation direction of the second motor can be controlled, enabling the three groups of racks to extend and retract in the fixed block.

[0033] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0034] A bimetal coiled sleeve weld grinding device, as Figure 1-7As shown in the figure, it includes a workbench 1. There is a grinding structure 7 on the top of the workbench 1. A support block 12 is fixedly connected to the top of the workbench 1. A first motor 13 is fixedly connected to the inside of the support block 12. The output end of the first motor 13 is fixedly connected to a driving disk 14. A three-jaw chuck 9 is fixedly connected to the inside of the driving disk 14. There are multiple groups of jaws 10 on the three-jaw chuck 9. A bushing body 11 is snap-connected inside the multiple groups of jaws 10. A fixed block 16 is fixedly connected to one side of the three-jaw chuck 9. A first rack 19, a second rack 20, and a third rack 21 are slidably connected inside the fixed block 16. End parts of the first rack 19, the second rack 20, and the third rack 21 are all fixedly connected with bumps. The bumps are all in contact with the inner wall of the bushing body 11. A first gear 29, a second gear 30, and a third gear 31 used in cooperation with the first rack 19, the second rack 20, and the third rack 21 are arranged inside the fixed block 16. A transmission structure used in cooperation with the first gear 29, the second gear 30, and the third gear 31 is rotatably connected to one side of the three-jaw chuck 9.

[0035] During use, first, the bushing body 11 is fixed on the three-jaw chuck 9 through the three-jaw chuck 9 and the jaws 10. Secondly, the first gear 29, the second gear 30, and the third gear 31 are rotated inside the fixed block 16 through the transmission structure. Through the mutual cooperation between the first gear 29, the second gear 30, and the third gear 31 and the first rack 19, the second rack 20, and the third rack 21, the first rack 19, the second rack 20, and the third rack 21 can be synchronously extended, so that the bumps are in contact with the inner wall of the bushing body 11. Then, through the outward expanding force of the three groups of racks and the bumps, the bushing body 11 is limited and fixed from the inside, which can assist the three-jaw chuck 9 to stably fix the bushing body 11 above the workbench 1. Then, through the mutual cooperation between the first motor 13 and the driving disk 14, the bushing body 11 performs a rapid rotational movement. Finally, the welding seam on the bushing body 11 is ground through the grinding structure 7. Finally, through the mutual cooperation between the first rack 19, the second rack 20, the third rack 21, the bumps, and the three-jaw chuck 9, the bushing body 11 can be clamped and fixed from the inside to the outside, which can not only make the bushing body 11 be clamped more stably, but also play an auxiliary role for the bushing body 11, avoiding excessive extrusion of the three-jaw chuck 9 and causing deformation of the bushing body 11, thereby improving the practicability and flexibility of the entire bimetallic coiled bushing welding seam grinding device.

[0036] Furthermore, the transmission disk 25 is driven by the second motor 15 to perform circular motion. Through the mutual cooperation between the connecting rod 26 and the second connecting rod 28, the third toothed ring 24 is driven to move synchronously with the second toothed ring 23. Since the first connecting rod 27 is fixedly connected between the second toothed ring 23 and the first toothed ring 22, the three toothed rings can be rotated synchronously. Through the meshing state between the three toothed rings and the three gears, when the first toothed ring 22, the second toothed ring 23 and the third toothed ring 24 rotate, the first gear 29, the second gear 30 and the third gear 31 can be driven to move synchronously. And the three gears are meshed with the three racks. Therefore, when the three gears move synchronously, the three racks will be driven to move synchronously. According to actual usage requirements, the rotation direction of the second motor 15 can be controlled so that the three racks can extend and retract in the fixed block 16. An installation groove 17 for the first gear 29, the second gear 30 and the third gear 31 is provided in the fixed block 16. The first gear 29, the second gear 30 and the third gear 31 protrude from the fixed block 16. A sliding groove 18 for the first rack 19, the second rack 20 and the third rack 21 is provided in the fixed block 16. The first rack 19, the second rack 20 and the third rack 21 are evenly distributed in the fixed block 16. The angles between the first rack 19, the second rack 20 and the third rack 21 are equal, and the first rack 19, the second rack 20 and the third rack 21 are not in the same horizontal line and are in a stepped shape. The first rack 19, the second rack 20 and the third rack 21 are in a stepped shape. The first toothed ring 22, the second toothed ring 23 and the third toothed ring 24 are respectively located in the first rack 19, the second rack 20 and the third rack 21. Therefore, the first connecting rod 27 and the second connecting rod 28 are not in the same horizontal line either and are in a stepped shape like the three racks. At the same time, the first connecting rod 27 is located on one side of the first rack 19, and the second connecting rod 28 is located on one side of the third rack 21. When the second motor 15 drives the transmission disk 25 to perform circular motion, the first connecting rod 27 and the second connecting rod 28 will not be blocked by the three racks. Secondly, the maximum rotation angle of the transmission disk 25 will not exceed the angle between the two racks. Therefore, the two connecting rods and the three racks will not affect each other.

[0037] In this embodiment, the provided slotted grooves enable the first gear ring 22, the second gear ring 23, and the third gear ring 24 to flexibly perform circular motion outside the fixed block 16 without being restricted in rotational motion by the first rack 19, the second rack 20, and the third rack 21. The provided protective shell 2 can protect the grinding process, prevent dust from flying, and is also conducive to the transfer and cleaning of powder debris in a closed environment, improving the safety of the powder debris cleaning process. The cooperation among the sliding door 3 composed of multiple plates with different thicknesses, the handle 4, and the movable groove 8 is conducive to the loading and unloading of the bushing. The provided air guiding block 6 can assist the grinding structure 7 in grinding the bushing body 11, preventing welding slag waste from splashing everywhere and affecting the collection effect of the waste. Finally, the provided aggregate box 5 can collect the waste generated during the grinding process and then conduct unified treatment. Through the movable cavity in the driving disk 14, the second motor 15 can be fixed in the driving disk 14 and does not rotate simultaneously with the driving disk 14, enabling the second motor 15 to normally drive the transmission disk 25 to work.
