Technical Field
[0001] This utility model relates to the field of grinding device technology, and in particular to a grinding device for the surface of a rod bracket. Background Technology
[0002] A rod bracket surface grinding device is a piece of equipment used for surface treatment of rod brackets made of metal or other materials. Its main function is to achieve a smooth and uniform surface through grinding or polishing, removing burrs, oxide layers, or other impurities, thereby improving surface quality. This device is typically equipped with abrasives of different specifications and automatic adjustment components, enabling precision machining according to the shape and material of the rod. It is widely used in machinery manufacturing, the automotive industry, metal processing, and other fields to ensure product quality and precision.
[0003] A search revealed that CN214770947U discloses a deburring device for a skeleton oil seal, comprising a worktable and a grinding mechanism. The grinding mechanism is mounted on the worktable and has a limiting mechanism installed on it. The limiting mechanism includes a connecting rod, a hollow platform, a limiting rod, a spring, a connecting block, a limiting clamp, a fixing sleeve, a limiting plate, and a compression spring. The connecting rod is mounted on the grinding mechanism, and its front end face has a horizontally formed groove. The hollow platform is located at the end of the connecting rod away from the grinding mechanism. The limiting rod is mounted on the hollow platform and is adjacent to the connecting rod. The spring is located inside the groove, with one end connected to the grinding mechanism and the other end in contact with the limiting rod. A connecting block is installed at the end of the hollow platform away from the limiting rod. A limiting clamp is installed on the side of the connecting block away from the hollow platform. This utility model, through the setting of the limiting mechanism, facilitates better fixation of the oil seal skeleton position.
[0004] The aforementioned patent has a relatively limited grinding angle for the grinding head on the skeleton during use, which makes it inconvenient to grind the skeleton at different angles. Furthermore, the grinding head has poor mobility, which reduces the convenience of grinding. Therefore, a rod bracket surface grinding device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a surface grinding device for rod brackets, which aims to improve the problem that the grinding head in the prior art has a relatively single grinding angle on the skeleton, making it inconvenient to grind and process the inclined surfaces of the skeleton at different angles.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A surface polishing device for a rod bracket includes a worktable, a moving mechanism mounted on the top of the worktable, an adjusting mechanism mounted on the bottom of the moving mechanism, a polisher mounted on the bottom of the adjusting mechanism, and clamping mechanisms mounted on both sides of the top of the worktable.
[0008] The adjustment mechanism includes a support plate, and multiple fixed plates are fixedly connected to the bottom of the support plate. A motor is installed on one side of two of the fixed plates. A rotating ring is fixedly connected to the drive end of the motor. A ball is movably connected to the bottom of the support plate. A support block is fixedly connected to the bottom of the ball. The bottom of the support block is fixedly connected to the top of the grinder. A collection component is provided on the outside of the worktable.
[0009] Through the above technical solution: the moving mechanism drives the grinder to move along the horizontal and vertical directions of the worktable to achieve three-dimensional positioning; the motor of the adjusting mechanism drives the rotating ring to rotate; the universal movement of the ball drives the support block to tilt, so that the grinder adapts to the curvature of the workpiece surface; the clamping mechanism symmetrically clamps the workpiece to ensure grinding stability; during the grinding process, the collecting component moves synchronously with the moving mechanism to automatically clean and recycle processing debris.
[0010] As a further description of the above technical solution:
[0011] The moving mechanism includes a first moving cylinder, the bottom of which is fixedly connected to the top of the worktable. A first moving slide rail is fixedly connected to the top of the worktable. A first sliding block is slidably connected to the top of the first moving slide rail. A support frame is fixedly connected to the top of the first sliding block. A second moving cylinder is fixedly connected to the top of the support frame. A second moving slide rail is fixedly connected to the bottom of the support frame. A second sliding block is slidably connected to the outside of the second moving slide rail. A hydraulic cylinder is fixedly connected to the bottom of the second sliding block. The drive end of the hydraulic cylinder is fixedly connected to the top of the support plate.
[0012] Through the above technical solution: the first moving cylinder drives the first sliding block to move laterally along the first moving slide rail to achieve the horizontal coarse adjustment of the grinder; the second moving cylinder drives the second sliding block to move vertically along the second moving slide rail through the support frame to complete the height fine adjustment of the grinder; the hydraulic cylinder rises and falls synchronously with the second sliding block to apply controllable pressure to the support plate to ensure that the contact pressure between the grinder and the workpiece surface is constant; finally, through the coordinated control of horizontal and vertical movements, the three-dimensional spatial position of the grinder is precisely adjusted.
[0013] As a further description of the above technical solution:
[0014] The drive end of the first movable cylinder is fixedly connected to one side of the first sliding block, and the drive end of the second movable cylinder is fixedly connected to one side of the second sliding block.
[0015] Through the above technical solution: the first moving cylinder directly pushes the first sliding block to move laterally along the first moving slide rail through the drive end, so as to realize the horizontal coarse adjustment of the grinder; the second moving cylinder directly drives the second sliding block to move vertically along the second moving slide rail through the drive end, so as to complete the height fine adjustment of the grinder. The two cylinders independently control the horizontal and vertical displacement of the sliding block. Through the superposition of bidirectional linear motion, the processing position of the grinder in three-dimensional space is precisely adjusted.
[0016] As a further description of the above technical solution:
[0017] The collection component includes two collection boxes, which are slidably connected to both sides of the workbench. A cleaning plate is fixedly connected to one side of the sliding block, and material collection troughs are provided on both sides of the top of the workbench.
[0018] Through the above technical solution: when the sliding block moves laterally, it drives the cleaning plate to move synchronously. The cleaning plate pushes the grinding debris on the surface of the workbench into the collection troughs on both sides. The debris slides along the inclined surface of the collection trough into the collection boxes that are slidably connected to both sides of the workbench, realizing the automatic cleaning and centralized recycling of debris in the processing area.
[0019] As a further description of the above technical solution:
[0020] The bottom of the cleaning plate contacts the top of the workbench, and the outside of the support block is slidably connected to the inner wall of the rotating ring.
[0021] The above technical solution allows for the cleaning of the workbench surface using a cleaning plate, and makes the sliding of the support block on the rotating ring more stable.
[0022] As a further description of the above technical solution:
[0023] The clamping mechanism includes two fixed blocks, which are respectively fixedly connected to the top sides of the workbench. A second motor is installed on the inner wall of the fixed block. A rotating plate is fixedly connected to the drive end of the second motor. Two adjustment slots are opened on the outside of the rotating plate. A sliding rod is slidably connected to the inner wall of the adjustment slot. A positioning plate is fixedly connected to the other end of the sliding rod.
[0024] Through the above technical solution: the motor drives the rotating plate to rotate, and the curved trajectory of the adjustment groove forces the sliding rod to move linearly along the groove towards the workpiece, driving the positioning plate to move synchronously towards the center. The symmetrical clamping mechanisms on both sides are linked by the synchronously rotating rotating plate and the adjustment groove, so that the double positioning plates clamp the workpiece with equidistant linear movement, achieving stable fixation in the center.
[0025] As a further description of the above technical solution:
[0026] A fixed platform is fixedly connected to one side of the fixed block, and two sliding grooves are opened on one side of the fixed platform. The outer side of the sliding rod is slidably connected to the inner wall of the sliding groove.
[0027] The above technical solution uses a groove on a fixed platform to restrict the sliding of the sliding rod, ensuring stability.
[0028] As a further description of the above technical solution:
[0029] A limiting slide rail is fixedly connected to one side of the fixed platform, and two moving blocks are slidably connected to the outside of the limiting slide rail. One side of the moving blocks is fixedly connected to one side of the positioning plate.
[0030] The above technical solution restricts the movement of the moving block by limiting the sliding, thereby restricting the movement of the positioning plate.
[0031] This utility model has the following beneficial effects:
[0032] 1. In this utility model, the rotating ring can flexibly adjust the position of the support block through the drive of motor one, thereby driving the grinder to adjust the angle. This design allows the grinder to precisely grind the workpiece from multiple angles, improving the comprehensiveness and uniformity of the workpiece surface treatment. Through the coordinated operation of two motors one, the equipment can achieve precise control in different positions, improving work efficiency and processing accuracy. In addition, the adjustable and automated design of the equipment makes operation more convenient, reduces the complexity of manual adjustment, and improves the work efficiency of the production line.
[0033] 2. In this utility model, through precise mechanical structure design, stable clamping and fixing of workpieces can be achieved. The motor drives the rotating plate to move the adjusting groove and sliding rod precisely, ensuring the smooth sliding of the positioning plate.

[0040] 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.
[0041] Reference Figures 2 to 3 The present invention provides an embodiment of a rod bracket surface grinding device, comprising a worktable 1, a moving mechanism 2 mounted on the top of the worktable 1, an adjusting mechanism 3 mounted on the bottom of the moving mechanism 2, a grinder 4 mounted on the bottom of the adjusting mechanism 3, and clamping mechanisms 6 mounted on both sides of the top of the worktable 1. The moving mechanism 2 achieves three-dimensional spatial positioning of the grinder 4 through a drive, and with the symmetrical clamping of the clamping mechanism 6, ensures that the workpiece remains stable during the grinding process.
[0042] Specifically, the moving mechanism 2 drives the adjusting mechanism 3 and the grinder 4 to move laterally and vertically on the worktable 1 to adjust the grinding position. The adjusting mechanism 3 changes the tilt angle of the grinder 4 through its internal mechanical structure to adapt to the curvature of the workpiece surface. The clamping mechanism 6 is symmetrically installed on both sides of the worktable 1 to fix the workpiece in both directions. During the grinding process, the moving mechanism 2 and the adjusting mechanism 3 work together to control the trajectory and angle of the grinder 4 to complete the comprehensive grinding of the workpiece surface.
[0043] The adjustment mechanism 3 includes a support plate 31, with multiple fixed plates 32 fixedly connected to the bottom of the support plate 31. A motor 33 is installed on one side of two of the fixed plates 32. The motor 33 is fixed below the support plate 31 through the fixed plates 32, providing an independent drive source for subsequent angle adjustment. A rotating ring 34 is fixedly connected to the drive end of the motor 33. A ball 35 is movably connected to the bottom of the support plate 31. A support block 36 is fixedly connected to the bottom of the ball 35. The motor 33 drives the rotating ring 34 to rotate, and the universal movement of the ball 35 causes the support block 36 to change its tilt angle. The bottom of the support block 36 is fixedly connected to the top of the grinder 4. The outside of the support block 36 is slidably connected to the inner wall of the rotating ring 34. The sliding constraint of the inner wall of the rotating ring 34 on the support block 36 ensures that the grinder 4 always maintains effective contact with the workpiece when tilting.
[0044] Specifically, motor 33 drives rotating ring 34 to rotate. The inner wall of rotating ring 34 is connected to support block 36 to constrain its movement trajectory. When rotating ring 34 rotates, support block 36 is guided by the inner wall to change its tilt angle. At the same time, the universal movement characteristic of ball 35 allows support block 36 to deflect in multiple directions, which ultimately drives grinder 4 to adjust the tilt angle so that it always fits the curvature of workpiece surface for grinding.
[0045] The moving mechanism 2 includes a moving cylinder 21, the bottom of which is fixedly connected to the top of the worktable 1. A moving slide rail 22 is fixedly connected to the top of the worktable 1. The moving cylinder 21 drives the sliding block 23 to move laterally along the moving slide rail 22 to achieve horizontal coarse positioning of the grinder 4. The top of the moving slide rail 22 is slidably connected to the sliding block 23. A support frame 24 is fixedly connected to the top of the sliding block 23. A moving cylinder 25 is fixedly connected to the top of the support frame 24. The moving cylinder 25 drives the sliding block 27 to move vertically through the support frame 24 to complete the fine height adjustment of the grinder 4.
[0046] Specifically, the first movable cylinder 21 drives the first sliding block 23 to move laterally along the first movable slide rail 22 to achieve the horizontal coarse adjustment of the grinder 4. The second movable cylinder 25 drives the second sliding block 27 to move vertically through the support frame 24 to complete the fine height adjustment of the grinder 4. The two cylinders work together to accurately control the three-dimensional spatial position of the grinder 4 through the superposition of horizontal and vertical movements, ensuring that it covers the entire grinding area of the workpiece surface.
[0047] refer to Figure 1 The collection component 5 includes two collection boxes 51, which are slidably connected to both sides of the workbench 1. A cleaning plate 52 is fixedly connected to one side of the sliding block 23. The cleaning plate 52 moves synchronously with the sliding block 23 to continuously push the processing debris into the collection trough 53 for centralized recycling.
[0048] Specifically, when the cleaning plate 52 moves laterally with the sliding block 23, its bottom end contacts the surface of the worktable 1, continuously pushing the grinding debris into the collection trough 53. The debris slides into the collection box 51 that is slidably connected on both sides through the inclined structure of the collection trough 53, realizing automatic cleaning and centralized recycling of debris in the processing area.
[0049] refer to Figure 4 The clamping mechanism 6 includes two fixed blocks 61, which are fixedly connected to the top sides of the worktable 1 respectively. The two fixed blocks 61 are symmetrically installed on both sides of the worktable 1 to form a bidirectional clamping layout, ensuring that the workpiece is centered. A second motor 62 is installed on the inner wall of the fixed block 61. The second motor 62 serves as the clamping power source and achieves stable torque output through the mounting structure of the fixed blocks 61. A rotating plate 63 is fixedly connected to the drive end of the second motor 62. The second motor 62 drives the rotating plate 63 to rotate, transmitting the rotational motion to the adjusting groove 64 and initiating the clamping process. Two adjusting grooves 64 are opened on the outside of the rotating plate 63. The curved trajectory design of the adjusting grooves 64 converts the rotational motion of the rotating plate 63 into the linear displacement of the sliding rod 65. The sliding rod 65 is slidably connected to the inner wall of the adjusting groove 64. The sliding rod 65 slides along the trajectory of the adjusting groove 64, converting the rotational motion into the linear motion required for clamping. A positioning plate 66 is fixedly connected to the other end. The linear movement of the sliding rod 65 directly drives the positioning plate 66 to move toward the workpiece to complete the clamping action. A fixed platform 67 is fixedly connected to one side of the fixed block 61. The fixed platform 67 provides a sliding path reference for the sliding rod 65 to ensure the linear accuracy of the clamping movement. Two sliding grooves are opened on one side of the fixed platform 67. The outer side of the sliding rod 65 is slidably connected to the inner wall of the sliding groove. The sliding groove provides a hard constraint on the movement path of the sliding rod 65 to eliminate trajectory deviation during the clamping process. A limiting slide rail 68 is fixedly connected to one side of the fixed platform 67. The limiting slide rail 68 cooperates with the moving block 69 to prevent the positioning plate 66 from radially shifting during clamping. Two moving blocks 69 are slidably connected to the outer side of the limiting slide rail 68. One side of the moving block 69 is fixedly connected to one side of the positioning plate 66. The moving block 69 slides along the limiting slide rail 68 to keep the positioning plate 66 always on a linear clamping trajectory and avoid workpiece misalignment.
[0050] Specifically, motor 62 drives rotating plate 63 to rotate, and the curved trajectory of adjusting groove 64 forces sliding rod 65 to move linearly along the slide groove of fixed platform 67, pushing positioning plate 66 to linearly displace towards the workpiece. The slide groove of fixed platform 67 rigidly constrains the path of sliding rod 65, and restricts the radial offset of positioning plate 66 by sliding block 69 through slide rail 68, ensuring that double positioning plates 66 clamp the workpiece synchronously along a straight line, achieving centered and stable clamping.
[0051] Working principle: When the equipment is needed, the workpiece to be processed is placed on one side of the two positioning plates 66. At this time, the second motor 62 is started, which drives the rotating plate 63 to rotate. The rotation of the rotating plate 63 will drive the adjusting groove 64 to move. The movement of the adjusting groove 64 will allow the sliding rod 65 to slide in the groove of the fixed table 67. At this time, the sliding rod 65 will drive the positioning plate 66 to move. The positioning plate 66 will control the moving block 69 to slide on one side of the limiting slide rail 68, thereby ensuring the stability of the sliding of the positioning plate 66. Finally, the workpiece is clamped and fixed by the movement of the positioning plate 66.
[0052] At this time, by activating the first moving cylinder 21, the first moving block 23 is moved. The movement of the first moving block 23 can move the support frame 24, allowing the support frame 24 to be adjusted. In conjunction with activating the second moving cylinder 25, the second moving block 27 is moved to one side of the second moving slide rail 26. The movement of the second moving block 27 controls the movement of the hydraulic cylinder 28. Finally, by activating the hydraulic cylinder 28, the adjusting mechanism 3 is moved, which in turn moves the grinder 4. The grinder 4 is used to grind the workpiece. By adjusting the position of the grinder 4, the various parts of the workpiece can be ground.
[0053] During the grinding process, the motor 33 can be started, which drives the rotating ring 34 to rotate. The rotation of the rotating ring 34 controls the rotation of the support block 36. The two motors 33 drive the rotating ring 34 to rotate in different directions, thereby flexibly adjusting the position of the support block 36. This allows the support block 36 to drive the grinder 4 to adjust its angle, enabling grinding operations on the workpiece from different angles, thus improving the ease of use and grinding efficiency of the equipment.
[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
