[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a centerless grinder for automotive parts processing. Background Technology

[0002] Automotive parts are various units that make up the whole car. According to their functions, they can be divided into categories such as core transmission, running brake, and body structure. Their machining accuracy directly affects the safety, reliability and service life of the car. Centerless grinder is a high-precision grinder that does not require fixing the workpiece center and achieves external cylindrical machining through the cooperation of grinding wheel, guide wheel and support plate. Due to its high efficiency and stable accuracy, it has become the core equipment for the precision machining of the external cylindrical parts of automotive parts.

[0003] To address this issue, patent publication CN214559539U discloses a centerless grinder for processing automotive parts. The grinder body includes a worktable fixedly connected to its bottom.

A transmission box is fixedly connected to the right side of the inner wall of the worktable, and a motor is fixedly connected to the top of the inner wall of the transmission box. A winding wheel is fixedly connected to the output end of the motor. This invention solves the problem that the wastewater treatment tank of most existing centerless grinders on the market is manually moved, which is time-consuming and labor-intensive, and may cause injury to the user during transport, thus burdening the user and reducing the practicality of the centerless grinder. This invention achieves the effect of moving the water tank to a convenient location for easy removal by the user.

[0004] The aforementioned centerless grinder for automotive parts processing addresses the problem that most existing centerless grinders on the market require manual handling of the wastewater treatment tank, which is time-consuming, labor-intensive, and prone to causing injury to the user during transport, thus burdening the user and reducing the practicality of the centerless grinder to some extent. The present invention moves the water tank to a convenient location for easy removal by the user. However, during use, the grinding wheels cannot adapt to parts of different sizes and models, and the position between the grinding wheels needs to be adjusted. Utility Model Content

[0005] The purpose of this invention is to provide a centerless grinder for processing automotive parts, which solves the problem that existing centerless grinders for processing automotive parts have difficulty adjusting the grinding wheel spacing.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a centerless grinder for processing automotive parts, including a water tank;

[0007] The bottom of the water tank is equipped with support legs, the side of the water tank is equipped with a water inlet, the top of the water tank is equipped with a workbench, and the top of the workbench is equipped with a placement plate.

[0008] The top of the workbench is equipped with a housing, inside which a grinding wheel is installed. A rotary motor is installed at one end of the grinding wheel, and a moving mechanism is installed at the bottom of the housing.

[0009] The moving mechanism is disposed in a moving slot including the top of the worktable. A moving block is installed inside the moving slot. A screw rod passes through the middle of the moving block, and a servo motor is installed on one side of the screw rod.

[0010] In use, the parts can first be placed on the placement plate. The fixed plate and the limiting plate are connected by a threaded rod. The threaded rod and the fixed plate form a threaded connection. Tightening the threaded rod will drive the limiting plate to move and clamp the parts between them, which can prevent the parts from shifting back and forth. The connecting rod can guide the limiting plate. Then, the rotating motor will drive the grinding wheel to rotate, and the rotating grinding wheel will grind the parts.

[0011] Furthermore, a cooling mechanism is installed at one end of the water tank. The cooling mechanism includes a water pump installed on one side of the water tank, and a conduit is installed at one end of the water pump. An installation plate is installed at the top of the conduit. The cooling mechanism can polish the parts.

[0012] Furthermore, an atomizing nozzle is installed at the bottom of the mounting plate, and the atomizing nozzles are arranged at equal intervals at the bottom of the mounting plate. The atomizing nozzles can spray water to cool the components.

[0013] Furthermore, a limiting structure is installed at the top of the placement plate, and the limiting structure includes a fixing plate installed at the top of the placement plate, a connecting rod installed at the top of the fixing plate, a limiting plate installed at one end of the connecting rod, a threaded rod installed at one end of the limiting plate, and a rotating block installed at one end of the threaded rod. The limiting structure can limit the movement of the parts.

[0014] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the fixing plate is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the fixing plate are threadedly connected, and the rotation of the threaded rod can drive the moving block to move.

[0015] Furthermore, guide rods extend through both ends of the movable block, and the guide rods are symmetrically distributed about the central axis of the movable block, so that the guide rods can guide the movable block.

[0016] Furthermore, the outer diameter of the moving block is smaller than the inner diameter of the moving groove, and the moving block and the moving groove form a sliding structure, allowing the moving block to slide within the moving groove.

[0017] The centerless grinder for processing automotive parts provided by this utility model has the following advantages: during use, the parts can be limited by the limiting structure to prevent them from moving back and forth; the position between the grinding wheels can be adjusted by the moving mechanism; and the grinding position can be cooled by the cooling mechanism.

[0018] By installing a movable block at the bottom of the housing, the threads on the screw are symmetrically distributed about the central axis of the screw. Therefore, the rotation of the screw will drive the movable block to move in the opposite direction. The operation of the servo motor will drive the screw to rotate, and the rotation of the screw will drive the movable block to move in the opposite direction. The movement of the movable block will drive the housing and the grinding wheel to move. This allows the position of the grinding wheel to be adjusted so that the grinding wheel can adapt to different situations. The guide rod passes through the movable block and can prevent the movable block from deviating during movement. This achieves the purpose of facilitating the adjustment of the grinding wheel position in the centerless grinder used for machining automotive parts.

[0019] By installing a water inlet on one side of the water tank, water can be filled into the tank. When the water pump works, it draws water out of the tank and sends it through a conduit into the atomizing nozzle. The atomizing nozzle atomizes the water and sprays it out, which cools the polished parts. Because the atomized water sprayed from the nozzle evaporates quickly, no excess water is left behind. This achieves the purpose of facilitating the cooling of parts in centerless grinders used for automotive parts processing. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1-5 One embodiment of this utility model is a centerless grinder for processing automotive parts, including a water tank 2.

[0028] The bottom of the water tank 2 is equipped with a support leg 3, and one end of the water tank 2 is equipped with a cooling mechanism 4. The cooling mechanism 4 includes a water pump 401 installed on one side of the water tank 2, and one end of the water pump 401 is equipped with a conduit 402. The top end of the conduit 402 is equipped with a mounting plate 403, and the bottom end of the mounting plate 403 is equipped with an atomizing nozzle 404. The atomizing nozzles 404 are arranged at equal intervals at the bottom end of the mounting plate 403.

[0029] See attached document Figure 1-2 and attached Figure 4 As shown, water can be filled into the water tank 2 through the water inlet 5. When the water pump 401 is working, it will drive the water in the water tank 2 to be drawn out, and then send the water into the atomizing nozzle 404 through the conduit 402. The atomizing nozzle 404 can atomize the water and spray it out. The sprayed water can cool the polished parts. Because the atomized water sprayed by the atomizing nozzle 404 will evaporate quickly, no excess water will be left.

[0030] A water inlet 5 is installed on one side of the water tank 2. A workbench 1 is installed on the top of the water tank 2. A placement plate 9 is installed on the top of the workbench 1. A limiting structure 10 is installed on the top of the placement plate 9. The limiting structure 10 includes a fixing plate 1001 installed on the top of the placement plate 9. A connecting rod 1003 is installed on the top of the fixing plate 1001. A limiting plate 1002 is installed on one end of the connecting rod 1003. A threaded rod 1004 is installed on one end of the limiting plate 1002. External threads are evenly arranged on the outer side wall of the threaded rod 1004. Internal threads that cooperate with the external threads are evenly arranged on the inner side wall of the fixing plate 1001. The threaded rod 1004 and the fixing plate 1001 are threadedly connected. A rotating block 1005 is installed on one end of the threaded rod 1004.

[0031] See attached document Figure 1-2 and attached Figure 5 As shown, the parts can be placed on the placement plate 9. The fixing plate 1001 and the limiting plate 1002 are connected by a threaded rod 1004. The threaded rod 1004 and the fixing plate 1001 form a threaded connection. Twisting the rotating block 1005 drives the threaded rod 1004 to rotate, which in turn drives the limiting plate 1002 to move and clamp the parts between them, preventing the parts from shifting back and forth. The connecting rod 1003 can guide the limiting plate 1002. Then, the rotating motor 8 will drive the grinding wheel 7 to rotate, and the rotating grinding wheel 7 will grind the parts.

[0032] The top of the workbench 1 is fitted with a housing 6, inside which a grinding wheel 7 is installed. A rotary motor 8 is installed at one end of the grinding wheel 7, and a moving mechanism 11 is installed at the bottom of the housing 6.

[0033] The moving mechanism 11 is disposed in the moving groove 1105 including the top of the worktable 1. The moving block 1103 is installed inside the moving groove 1105. The outer diameter of the moving block 1103 is smaller than the inner diameter of the moving groove 1105. The moving block 1103 and the moving groove 1105 constitute a sliding structure.

[0034] Guide rods 1104 penetrate both ends of the movable block 1103, and the guide rods 1104 are symmetrically distributed about the central axis of the movable block 1103.

[0035] A screw 1102 passes through the middle of the moving block 1103, and a servo motor 1101 is installed on one side of the screw 1102.

[0036] See attached document Figure 1-3As shown, the movable block 1103 can slide inside the movable groove 1105. The threads on the screw 1102 are symmetrically distributed about the central axis of the screw 1102. Therefore, the rotation of the screw 1102 will drive the movable block 1103 to move in the opposite direction. The operation of the servo motor 1101 will drive the screw 1102 to rotate. The rotation of the screw 1102 will drive the movable block 1103 to move in the opposite direction. The movement of the movable block 1103 will drive the housing 6 and the grinding wheel 7 to move. This allows the position of the grinding wheel 7 to be adjusted so that the grinding wheel 7 can adapt to different situations. The guide rod 1104 passes through the movable block 1103 and can prevent the movable block 1103 from deviating during movement.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
