Description

Technical Field

[0001] This utility model relates to the technical field of tool grinding machine processing, specifically to a tool grinding machine robot loading and unloading device. Background Technology

[0002] A tool grinder is a machine tool used for precision grinding of cutting tools and other tools. It generally includes basic components such as a bed, worktable, grinding wheel head, and headstock. To ensure the accuracy of material loading, a robotic arm is usually used for loading and unloading.

[0003] A search revealed Chinese patent application CN200720176857.4, which discloses a tool grinder robotic arm loading and unloading device. The device comprises a robotic arm with a reducer at its free end. A reducer connecting seat is rotatably connected to the reducer, a slide cylinder is connected to the reducer connecting seat, and a gripper fixing seat is connected to the slide cylinder. A pneumatic chuck is connected to each of the opposite sides of the gripper fixing seat, with a gripper forming a claw at the outer end of each pneumatic chuck. This invention is installed on a tool grinder. During use, the grippers of the pneumatic chucks clamp the material. When loading, the grippers abut against the tool grinder's clamping seat and apply force. The elasticity of the pneumatic chucks provides preload during loading, thereby achieving accurate loading, saving time, and facilitating processing and production.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Although robotic arms can facilitate workpiece loading, achieve accurate loading, and save time, in actual use, after loading, a significant amount of dust is typically generated during workpiece grinding. This dust not only pollutes the environment but also enters the gaps in the robotic arm joints, acting like an abrasive and causing friction with the component surface during joint movement, leading to movement jamming and malfunctions. Therefore, it is essential to design a practical and protective robotic arm loading and unloading device for tool grinders. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-4The present invention provides a technical solution: a tool grinding machine robot loading and unloading device, including a grinding machine 1, a vertical plate 2 fixedly connected to the upper side of the grinding machine 1, a grinding component 3 provided on one side of the vertical plate 2, a support block 4 fixedly connected to the upper side of the grinding machine 1 and outside the grinding component 3, a sliding groove 5 opened on the upper side of the support block 4, and a protective frame 6 slidably fitted on the inner wall of the sliding groove 5.

[0024] A feeding front arm 7 is provided on one side of the support block 4, a feeding rear arm 8 is provided at one end of the feeding front arm 7, a gripper 9 is provided on one side of the feeding rear arm 8, a force groove 10 is provided on one side of the support block 4, two limiting rods 11 that cooperate with the feeding front arm 7 are slidably fitted on the inner wall of the force groove 10, a force-generating toothed plate 12 is fixedly connected to the upper side of the two limiting rods 11, a linkage assembly 13 is provided between the force-generating toothed plate 12 and the protective frame 6, and a clamping assembly 14 is provided on the upper side of the grinding machine 1.

[0025] Please see Figure 4 The grinding assembly 3 includes a grinding motor 301 fixedly connected to one side of the vertical plate 2 and a grinding disc 302 fixedly connected to the output end of the grinding motor 301. By starting the grinding motor 301, the grinding disc 302 is driven to rotate. When the workpiece comes into contact with the grinding disc 302, the workpiece is ground by high-speed rotation and friction.

[0026] Please see Figure 2 The linkage component 13 includes a central gear 131 rotatably engaged with the upper side of the support block 4 and meshing with the force-generating gear plate 12, and a force-receiving gear plate 132 fixedly connected to one side of the protective frame 6 and meshing with the central gear 131. When the loading arm 8 rotates, the rotation of the loading arm 8 pushes the force-generating gear plate 12, and the force-generating gear plate 12 rotates the central gear 131, causing the force-receiving gear plate 132 to drive the protective frame 6 to move accordingly, thereby realizing the transmission between the force-generating gear plate 12 and the force-receiving gear plate 132.

[0027] Please see Figure 4 The clamping assembly 14 includes an electric slide rail 141 fixedly connected to the upper side of the grinding machine 1, a displacement block 142 slidably fitted on the electric slide rail 141, a sealing plate 143 fixedly connected to the displacement block 142 and cooperating with the protective frame 6, an electric push rod 144 fixedly connected to the displacement block 142, and a clamping part 145 fixedly connected to the output end of the electric push rod 144. The clamping part 145 can be the prior art and can clamp the workpiece. The electric slide rail 141 can drive the workpiece to a pre-grab position between the hands 9 for loading and unloading. Then the electric slide rail 141 moves the loaded workpiece to align with the grinding assembly 3, and the electric push rod 144 pushes the workpiece to realize the grinding operation.

[0028] Please see Figure 4A hidden groove 15 is provided on one side of the grinding machine 1. A collection frame 16 is slidably fitted on the inner wall of the hidden groove 15. By inserting the collection frame 16 into the hidden groove 15, it can be used to collect the debris generated during the processing inside the protective frame 6, thereby improving the convenience of subsequent maintenance.

[0029] Please see Figure 4 A guide trough 17 is provided on one side of the inner wall of the collection frame 16. A dustproof net 18 is fixedly connected to the inner wall of the guide trough 17. An air extractor 19 with its input end penetrating into the interior of the guide trough 17 is provided on one side of the collection frame 16. An air inlet 20 is provided on one side of the sealing plate 143. By starting the air inlet 19, air is extracted from the interior of the guide trough 17, and then the air extractor 19 is started to enter the interior, thereby guiding the air so that the generated dust moves downward with the air and is blocked by the dustproof net 18, allowing the dust to enter the interior of the collection frame 16, improving the convenience of subsequent cleaning and processing.

[0030] The implementation principle of this application is as follows: When in use, firstly, the grinding machine 1 is fixed in a suitable position and the internal electrical components are powered on. The angle of the feeding front arm 7 can be rotated by the control device at the lower end of the feeding front arm 7. Then, the feeding front arm 7 is equipped with a drive component that cooperates with the feeding rear arm 8, which can be used to adjust the direction of the feeding rear arm 8. The gripper 9 can be assembled using the existing technology of assembly frame, cylinder, and clamping gripper, and is mainly used to clamp materials, all of which are existing technologies.

[0031] When feeding is required, the feeding front arm 7, feeding rear arm 8, and gripper 9 are first controlled by a certain program to clamp the material. Then, while clamping the material, the feeding front arm 7 changes direction and moves towards the clamping assembly 14. During feeding, one of the limiting rods 11 is pressed, which drives the force-generating gear plate 12 to move. The force-generating gear plate 12 rotates the central gear 131, and the other side of the central gear 131 pushes the force-receiving gear plate 132, thereby pushing the protective frame 6 to separate from the sealing plate 143. The electric slide rail 141 drives the electric push rod 144 and the clamping part 145 to move to the corresponding position. The gripper 9 puts the clamped item into the clamping part 145, which fixes the workpiece. Then, the electric slide rail 141 drives the clamping assembly 14 to reset, and the feeding front arm 7 resets, which will squeeze the other limiting rod 11, thereby causing the force-generating gear plate 132 to move. 2. Moving away from the clamping assembly 14, the force-generating toothed plate 12 drives the force-receiving toothed plate 132 to move the protective frame 6 through the central gear 131, thereby aligning it with the sealing plate 143. Then, the grinding motor 301 is started to drive the grinding disc 302 to rotate. Through the electric push rod 144, the clamping part 145 and the internal material are pushed to contact the grinding disc 302 to achieve grinding. Thus, during feeding, the rotation of the feeding front arm 7 can open the protective frame 6 without affecting the movement of the clamping assembly 14. After feeding is completed, during the unloading process, the rotation of the feeding rear arm 8 controls the seal between the protective frame 6 and the sealing plate 143 again, achieving a seal for the grinding space. This reduces the dust generated during the grinding process and isolates the protective frame 6, maintaining a good working environment. It also reduces the damage of generated debris to the feeding front arm 7 and the feeding rear arm 8, improving the service life of this structure and the production environment.

[0032] During the polishing process, the air extraction fan 20 is activated to extract air from the inside of the air guide duct 17. Then, the air enters from the inside of the air inlet 20, thereby guiding the air so that the generated dust moves downward with the air and is blocked by the dust screen 18, allowing the debris to enter the inside of the collection frame 16, improving the convenience of subsequent cleaning and processing.
