Description

Technical Field

[0001] The invention relates to the field of tool grinding, in particular to a tool grinding device capable of automatically changing materials. Background Art

[0002] A tool head grinder is a device used to grind the tool head of a tool. The tool head is ground by a high-speed rotating grinding wheel, which is generally made of a material with a higher hardness, such as silicon carbide, cubic boron nitride, etc. The motor drives the grinding wheel to rotate. When the tool head contacts the rotating grinding wheel, the high-speed movement of the grinding wheel and its own grinding particles can remove the material on the surface of the tool head, thereby achieving the purpose of trimming the tool head shape, edge angle and sharpness. Some tool head grinders are also equipped with a precise feeding system, which can accurately control the contact pressure and feed speed between the tool head and the grinding wheel. By setting these parameters reasonably, the stability and accuracy of the grinding quality can be guaranteed.

[0003] In actual use, the existing tool grinding can generally only clamp one tool head at a time. If the equipment can only process one tool head at a time, it is difficult to meet the needs of large-scale production. The back and forth loading process will waste a certain amount of time. At the same time, the existing tooling plug plates generally only prepare two, which has certain deficiencies in material preparation. Summary of the invention

[0022] 1. By setting up the alternating components, two tools can be clamped at a time when the unprocessed tools are clamped. When the tools are loaded onto the grinder, there is no need to return to clamp the next material. Being able to clamp two tools at a time means that the number of loading and unloading times is halved compared to the method of clamping only one tool head at a time.

Both the loading of a single workpiece and the loading of the insert plate can be carried out efficiently. Since the clamping assembly directly receives and loads the material after grinding is completed, the number of times the workpiece is transferred between different devices is reduced, and reducing the number of transfers helps to maintain the accuracy of the workpiece.

[0024] 3. By setting up a feeding mechanism, the top of the loading platform of the feeding mechanism can always be kept in a vertical horizontal plane when collecting and loading materials. When loading the processed tools, it can be kept in the same horizontal plane with the three plug-in plates, so that the plug-in plates of the tools can be expanded to five, which greatly improves the processing efficiency. At the same time, the two loading platforms can also serve as the functions of collecting and loading materials respectively. The processed tools are placed on the plug-in plates and stacked on the loading platforms for collecting. Similarly, the plug-in plates with unprocessed tools can also be loaded. There are always plug-in plates for use before the unprocessed tools are used up. To a certain extent, automatic loading is realized, which improves work efficiency.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0039] See also Figure 1-10The present invention provides a technical solution: a tool grinding device capable of automatically changing materials, comprising a main frame 1, a driving mechanism 2 is arranged at the rear of the main frame 1, a material changing mechanism 3 is arranged on the driving mechanism 2, the material changing mechanism 3 comprises a rotating assembly 301, an alternating assembly 302 is arranged at the front of the rotating assembly 301, the alternating assembly 302 comprises a slotted plate 3021, an I-shaped lifting block 3024, a lifting plate 3025 and a special-shaped plate 30251, a first through slot 3022 and a second through slot 3023 are arranged on the plate body of the slotted plate 3021, a cylinder 30241 is arranged at the top end of the back of the slotted plate 3021, the I-shaped lifting block 3024 is clamped in the first through slot 3022, and the upper surface of the I-shaped lifting block 3024 is connected to the output end of the cylinder 30241, The lifting plate 3025 is arranged at the front of the I-shaped lifting block 3024, and a limiting piece is arranged on one side of the lifting plate 3025. The special-shaped plate 30251 is movably connected to the front of the lifting plate 3025 through a movable slide rail. A limiting shaft 30252 is inserted into the body of the special-shaped plate 30251, and one end of the limiting shaft 30252 is connected to the limiting piece of the lifting plate 3025. A spring 30253 is sleeved on the limiting shaft 30252, and a limiting pulley 30254 located in the second through groove 3023 is movably arranged at the end of the limiting shaft 30252. When in use, under the action principle of the lead screw, the first servo motor 2014 and the second servo motor 2023 are respectively arranged, the first slide groove 201 and the first slider 2012 move relatively, and the second slide groove 202 and the second The slider 2021 moves relative to each other, and the third slide groove 203 and the third slider 2031 move relative to each other, so that the material changing mechanism 3 can move up, down, left, right, and forward and backward. The fifth servo motor 30311 is set, and the threaded shaft 30331 rotates. Under the action principle of the lead screw, the movable plate 3033 moves downward, so that the first movable arm 3034 drives the clamping head 3037 downward to clamp the workpiece. After the first workpiece is clamped, the cylinder 30241 is driven to make the I-shaped lifting block 3024 on one side of the slotted plate 3021 move upward. After the limiting pulley 30254 moves to the top of the second through groove 3023, the spring 30253 drives the special-shaped plate 30251 to the center line of the slotted plate 3021. At this time, the limit pulley 30254 on the other side of the slotted plate 3021 is The positioning pulley 30254 moves to the bottom of the second through slot 3023. Similarly, the end of the special-shaped plate 30251 on the other side is also located at the center line of the slotted plate 3021. At this time, the clamping components 303 are one up and one down and are located on the same vertical line. The two move alternately, so that the unprocessed or processed workpiece can be clamped twice on the same axis. When processing the tool, it is only necessary to place the tool on the clamping head 3037 at the grinding position of the grinder 5 through the driving mechanism 2. When it is necessary to transfer one of the first plug plate 101, the second plug plate 102 and the third plug plate 103, the drive mechanism 2 is used to expand the inner circle of the structural member of the side frame 104 to pick up the plug plate. After placing it on the first loading platform 408 or the second loading platform 409,The loading platform will be pressed downward by gravity. After reaching a certain position, the first counterweight block 406 rises and reaches the bottom of the second counterweight block 4061. At this time, since the gravity has not reached the weight of the first counterweight block 406 plus the second counterweight block 4061, it will not continue to move upward. In the process of the first counterweight block 406 rising upward and reaching the bottom of the second counterweight block 4061, the loading platform will move downward by one unit of height. As long as the distance under the natural force of each counterweight block is equal to the distance from the bottom of the plugboard to the top of the side frame 104, it can be achieved. The load on the loading platform is now at the same height. The cooperation of the first plugboard 101, the second plugboard 102 and the third plugboard 103 is specifically as follows: during the processing, the blank on the first plugboard 101 is first clamped for processing, and then placed on the third plugboard 103. After all the products on the first plugboard 101 are processed, they become empty boards, and the third plugboard 103 is the finished product after processing. The whole board is taken away from the third plugboard 103, and the whole board blank is placed; then the blank on the second plugboard 102 is clamped for processing, and then placed on the first plugboard The first plug board 101 is an empty board, and the second plug board 102 becomes an empty board after all products are processed. The first plug board 101 is a finished product after processing. The first plug board 101 is taken away from the whole board, and the whole board blank is put in. Then the blank on the third plug board 103 is clamped for processing, and the blank is put into the second plug board 102 after processing. After all products on the third plug board 103 are processed, the empty board becomes the second plug board 102, and the second plug board 102 is a finished product after processing. The second plug board 102 is taken away from the whole board, and the whole board blank is put in. By setting the alternating component 302, the unprocessed tool is clamped. When the tool is held, two tools can be clamped at a time, and when the tool is loaded on the grinder 5, there is no need to return to clamp the next material. Being able to clamp two tools at a time means that in the process of loading and unloading tools, compared with the method of only clamping one tool head at a time, the number of loading and unloading times is halved. After the tool is loaded on the grinder 5, there is no need to return to clamp the next material, making the grinding process more coherent. The grinder 5 can grind the two tools in sequence without interruption, reducing the idling time of the equipment caused by frequent interruptions to clamp the tools.

After the limiting pulley 30254 moves to the top of the second through groove 3023, the spring 30253 drives the special-shaped plate 30251 to the center line of the slotted plate 3021. At this time, the limiting pulley 30254 on the other side of the slotted plate 3021 moves to the bottom of the second through groove 3023.

[0049] Specifically, the working process or working principle of the tool grinding device capable of automatic material change is as follows: when in use, under the action principle of the lead screw, the first servo motor 2014 and the second servo motor 2023 are respectively set, the first slide 201 and the first slider 2012 move relative to each other, the second slide 202 and the second slider 2021 move relative to each other, and the third slide 203 and the third slider 2031 move relative to each other, so that the material change mechanism 3 can move up, down, left, right, front and back, and the fifth servo motor 30311 is set, and the threaded shaft 30331 rotates. Under the action principle of the lead screw, the movable plate 3033 moves downward, so that the first movable arm 3034 drives the clamping head 3037 downward to move the tool. After the first workpiece is clamped, the cylinder 30241 is driven to make the I-shaped lifting block 3024 on one side of the slotted plate 3021 move upward. After the limiting pulley 30254 moves to the top of the second through slot 3023, the spring 30253 drives the special-shaped plate 30251 to the center line of the slotted plate 3021. At this time, the limiting pulley 30254 on the other side of the slotted plate 3021 moves to the bottom of the second through slot 3023. Similarly, the end of the special-shaped plate 30251 on the other side is also located at the center line of the slotted plate 3021. At this time, the clamping components 303 are one up and one down and are located on the same vertical line. The two move alternately, and the unprocessed or processed workpiece can be processed on the same axis. The tool is clamped twice. When processing the tool, it is only necessary to place the tool on the clamping head 3037 on the grinding position of the grinder 5 through the driving mechanism 2. When it is necessary to transfer one of the first plug plate 101, the second plug plate 102 and the third plug plate 103, the plug plate can be picked up by expanding the inner circle of the structural part of the side frame 104 through the driving mechanism 2. After being placed on the first loading platform 408 or the second loading platform 409, the loading platform will be pressed downward by gravity. After reaching a certain center, the first counterweight block 406 rises upward and reaches the bottom of the second counterweight block 4061. At this time, since the gravity does not reach the weight of the first counterweight block 406 plus the second counterweight block 4061, it will not continue to move upward. When a counterweight block 406 rises and reaches the bottom of the second counterweight block 4061, the loading platform will move downward by one unit of height. As long as the distance under the natural force of each counterweight block is equal to the distance from the bottom of the plugboard to the top of the side frame 104, the load on the loading platform can be located at the same height. The cooperation of the first plugboard 101, the second plugboard 102 and the third plugboard 103 is specifically that during the processing, the blank on the first plugboard 101 is first clamped for processing, and then placed on the third plugboard 103 after processing. After all the products on the first plugboard 101 are processed, they become empty boards, and the third plugboard 103 is the finished product after processing. The third plugboard 103 is taken away from the whole board, and the whole board blank is placed;Then, the blank on the second plug board 102 is clamped and processed, and after processing, it is placed on the empty first plug board 101. After all the products on the second plug board 102 are processed, it becomes an empty board. The first plug board 101 is the finished product after processing. The whole board takes away the first plug board 101 and puts in the blank. Then, the blank on the third plug board 103 is clamped and processed, and after processing, it is placed on the empty second plug board 102. After all the products on the third plug board 103 are processed, it becomes an empty board. The second plug board 102 is the finished product after processing. The whole board takes away the second plug board 102 and puts in the blank. ;
