Description

Technical Field

[0001] This utility model relates to the field of edge polishing technology, specifically to an edge polisher. Background Technology

[0002] Edge grinding, a crucial post-processing step in manufacturing, is widely used in numerous fields, including PVC pipes, transformer core silicon steel sheets, tempered glass, stainless steel plates, mechanical parts, and even precision circuit boards. Its purpose is to remove burrs, flash, sharp angles, and unevenness from the edges of workpieces after cutting or forming, thereby improving product dimensional accuracy, assembly performance, safety, and appearance quality. Traditional manual grinding methods are not only inefficient and labor-intensive, but also highly dependent on the operator's experience and skill level, making it difficult to guarantee product consistency and reliability. According to a detailed search, the authorized announcement number CN217475568U describes an automated ceramic fragment edge grinder. The grinding motor is mounted on the lower surface of the slider via a self-locking telescopic frame. The slider is driven by a lead screw on the surface of the servo motor. When grinding ceramic materials, a locking handwheel is used to press against the material surface. The servo motor rotates forward and backward, and the lead screw drives the slider to reciprocate, realizing reciprocating grinding of the material surface and improving grinding efficiency. However, existing edge grinders cannot position and fix workpieces of different sizes, which reduces the adaptability of the equipment. Therefore, we propose an edge grinder. Utility Model Content

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1, as Figures 1-4 As shown, this embodiment proposes an edge grinder, including a worktable 1, a fixed platform 2 fixedly connected to the outer surface of the worktable 1, a robot arm 3 connected to the outer surface of the fixed platform 2, a grinding gun 4 fixedly connected to the working end of the robot arm 3, and a clamping structure 6 connected to the outer surface of the worktable 1. A pad 5 is fixedly connected to the outer surface of the workbench 1. The clamping structure 6 includes a base plate 61 fixedly connected to the lower end of the workbench 1. An electric cylinder 62 is fixedly connected to the upper surface of the base plate 61. A limit post 63 is fixedly connected to the output end of the electric cylinder 62. There are several sets of electric cylinders 62. The limiting post 63 passes through the worktable 1 and slides up and down along the base plate 61. The maximum height of the electric cylinder 62 extending and lifting the limiting post 63 is higher than the top height of the pad block 5. The base plate 61 is fixedly connected to the worktable 1 with intervals through the bracket. There are several sets of brackets corresponding to one set of base plates 61 and they are distributed in an array. The several sets of electric cylinders 62 are set in four directions, namely front, back, left and right, which correspond to the four directions of the workpiece to be ground.

[0018] The outer surface of the workbench 1 has longitudinal grooves 64 and transverse grooves 65 respectively at the corresponding limiting posts 63 near the front and right sides or near the rear and left sides. The lower end of the electric cylinder 62 corresponding to the longitudinal groove 64 or transverse groove 65 on the outer surface of the base plate 61 is connected to the guide rail 66, and the lower end of the electric cylinder 62 is connected to the guide rail 66 with a slider 67. The lower end of the workbench 1 is fixedly connected to 68, and the outer surface of 68 is connected to the telescopic cylinder 69. The outer surface of the electric cylinder 62 corresponding to the guide rail 66 is fixedly connected to the guard plate 610. The output end of the telescopic cylinder 69 is connected to the guard plate 610, and the telescopic cylinder 69 is connected to the workbench 1 with a positioning bracket 611.

[0019] The slider 67 slides along the length of its corresponding guide rail 66. The slider 67 is fixedly connected to the lower end of the electric cylinder 62. The position of the electric cylinder 62 is adjusted by the extension and retraction of the telescopic cylinder 69. The length of the telescopic cylinder 69 is parallel to its corresponding longitudinal slide groove 64 or transverse slide groove 65. The length of the longitudinal slide groove 64 and the transverse slide groove 65 are perpendicular to each other. The positioning bracket 611 is fixedly connected to the worktable 1 by bolts. There are two sets of transverse slide grooves 65 on the left or right side. The two sets of electric cylinders 62 are stably connected by a set of guard plates 610. The transverse slide groove 65 can accommodate the limiting post 63 to slide inside it. The moving direction of the limiting post 63 corresponding to the longitudinal slide groove 64 at the front or rear is perpendicular to the moving direction of the limiting post 63 corresponding to the transverse slide groove 65 on the left or right side.

[0020] In this embodiment, the workpiece that needs edge grinding can be lifted and supported by the pad block 5. At the same time, the workpiece to be processed can be directly limited and fixed by the limiting post 63, which facilitates the edge grinding of the workpiece. When it is necessary to position and fix workpieces of different sizes, the workpiece can also be clamped and fixed from the four sides of the workpiece.

[0021] In summary, the working principle of this utility model is as follows: The principle is illustrated with the longitudinal slide 64 corresponding to the front and the transverse slide 65 corresponding to the right side as an example. When grinding the edge of the workpiece, the user can place the workpiece on the pad 5 and between several sets of limiting posts 63. When grinding the edge of the workpiece, the electric cylinder 62 only needs to extend upward so that the limiting posts 63 fix the workpiece around the perimeter. Then, through the operation of the robotic arm 3, the grinding head of the grinding gun 4 can be aligned with the part that needs to be ground to grind. When it is necessary to grind the edges of workpieces of different sizes, the corresponding electric cylinders 62 on the left and rear can be extended to allow the limiting post 63 to extend upward, thereby fixing the left and rear positions of the workpiece. Then, the electric cylinders 62 on the front and right can be extended until the top height of the limiting post 63 is the same and higher than the top height of the pad 5. Then, the telescopic cylinders 69 on the front and right can be extended to move the electric cylinders 62 in the front and right directions toward the workpiece until the limiting post 63 moves from the longitudinal slide 64 and the transverse slide 65 respectively, clamping the workpiece. Then, the robot arm 3 and the grinding gun 4 can perform edge grinding on the workpiece. The structure of the pad 5 allows the dust after grinding to fall onto the worktable 1, without affecting the workpieces processed on the pad 5.

[0022] It should be understood that in this application, all rotating, sliding, meshing, belt-driven, and other moving parts are well lubricated, making them less prone to slippage or wear, and each part is equipped with a corresponding protective housing. However, in the accompanying drawings of this application, the connection status of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets actual requirements. At the same time, the operation of some parts or structures requires automatic control by PLC, and the specific algorithm or program needs to be adjusted and set by the manufacturer to meet the requirements of actual application.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
