Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a cemented carbide grinding machine. Background Technology

[0002] A grinding machine is a machining tool used to perform precision grinding operations on workpieces. It can change the shape, size, and surface quality of workpieces by cutting and grinding their surfaces. Grinding machines are widely used in various fields of manufacturing, such as processing hardened steel, cemented carbide, and other high-hardness materials, or brittle materials such as glass and granite.

[0003] For example, CN220548060U discloses a carbide grinding machine, including a support base, a processing table, a base, a collection tank, a grinding device, and a rotating device. The grinding device includes a motor, a grinding head, a fixed frame, and an extension plate, which is connected to the fixed frame. A mounting rod is provided below the rotating device and is mounted on the support base. The rotating device includes a positioning plate, a worm gear, a worm wheel, and a locking structure. One end of the worm wheel is rotatably connected to the positioning plate, and the other end of the worm wheel is fixedly connected to the locking structure. The extension plate is mounted on the locking structure and slides with the locking structure. Using this invention, after grinding one surface of a large workpiece, rotating the worm gear causes the worm wheel to rotate, which in turn causes the grinding device to rotate, thus adjusting the workpiece's surface. This eliminates the need to disassemble the workpiece for surface adjustment, increasing grinding speed and production efficiency.

[0004] However, in the current technology, traditional equipment can usually only process one side of cemented carbide. When processing other sides, the cemented carbide needs to be flipped and fixed before subsequent processing can be completed. This operation is cumbersome and affects processing efficiency, thus limiting the practicality of the device to a certain extent. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that when processing other surfaces, it is necessary to flip the cemented carbide and fix it before completing subsequent processing, which is cumbersome and affects processing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cemented carbide grinding machine, comprising a bed, with supports fixedly installed at the four corners of the lower surface of the bed, and movable blocks symmetrically slidably installed on both sides of the upper surface of the bed. An installation cavity is formed inside each movable block, and a rotating clamping mechanism is provided on the surface of each movable block. The rotating mechanism includes a rotating block rotatably mounted on the surface of the movable block. A worm gear is fixedly installed at the center of the outer surface of the rotating block, and a screw is threaded at the center of the inner cavity of the rotating block. A positioning plate is driven at one end of the screw, and several return springs are elastically arranged in a ring shape between the positioning plate and the rotating block. A worm is drivenly installed in the inner cavity of the installation cavity below the worm gear, and a rotating rod is drivenly installed at one end of the worm. A lifting mechanism is provided on the lower surface of the bed.

[0007] In a preferred embodiment, the lifting mechanism includes a hydraulic cylinder, which is fixedly disposed at the center of the lower surface of the bed. The output end of the hydraulic cylinder is provided with a connecting plate, and the upper surface of the connecting plate is fixedly connected to the bottom end of the guide rod.

[0008] In a preferred embodiment, guide rods are symmetrically fixed on both sides of the lower surface of the bed, and a stop block is fixedly provided at the bottom end of the guide rod, and the guide rod is slidably connected to the connecting plate.

[0009] In a preferred embodiment, a processing table is fixedly installed on one side of the upper surface of the bed, a collection box is slidably installed in the inner cavity of the processing table, and filter holes are opened on the upper surface of the processing table.

[0010] In a preferred embodiment, a first mounting block is fixedly disposed on the other side of the upper surface of the bed, a first motor is fixedly disposed on the outer wall of the first mounting block, a first lead screw is driven in the inner cavity of the first mounting block, and one end of the first lead screw is drivenly connected to the output end of the first motor.

[0011] In a preferred embodiment, the surface of the first lead screw is provided with a first moving block, the top of the first moving block is fixedly provided with a limit electric push rod, and the top output end of the limit electric push rod is provided with a second mounting block.

[0012] In a preferred embodiment, the inner cavity of the second mounting block is provided with a second lead screw, the outer wall of the second mounting block is fixedly provided with a second motor, and one end of the second lead screw is connected to the output end of the second motor. The surface of the second lead screw is provided with a second moving block, and the bottom end of the second moving block is fixedly provided with a processing device.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention features a rotating clamping mechanism. Rotating the screw causes the positioning plate to move inwards, clamping and fixing both sides of the cemented carbide. Simultaneously, the positioning plate stretches the return spring, and by lifting the movable block, the cemented carbide rises to a certain height. Rotating the rotating rod then drives the worm gear, which in turn drives the rotating block via a worm wheel. The rotating block, through the screw, causes the positioning plate and the clamped cemented carbide to flip over. This eliminates the need for cumbersome disassembly and reassembly for subsequent processing, improving the device's practicality and processing efficiency.

[0015] This invention features a lifting mechanism. When the carbide needs to be flipped, the output end of the hydraulic cylinder drives the connecting plate to slide along the guide rod. The connecting plate then drives the movable block to rise and fall stably, thus ensuring the stable operation of the carbide flipping process and further improving the practicality and processing efficiency of the device.

[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 1-4 This utility model provides a technical solution: a cemented carbide grinding machine, including a bed 1, with supports 2 fixedly installed at the four corners of the lower surface of the bed 1, and movable blocks 3 symmetrically slidably installed on both sides of the upper surface of the bed 1. An installation cavity 16 is formed inside the movable block 3, and a rotating clamping mechanism is provided on the surface of the movable block 3. The rotating mechanism includes a rotating block 11 rotatably mounted on the surface of the movable block 3, a worm gear 15 fixedly installed at the center of the outer surface of the rotating block 11, and a screw 12 threadedly installed at the center of the inner cavity of the rotating block 11. A positioning plate 13 is driven at one end of the screw 12, and several return springs 14 are elastically arranged in an annular shape between the positioning plate 13 and the rotating block 11. The installation cavity 16... A worm 17 is installed in the inner cavity below the worm gear 15. A rotating rod 18 is installed at one end of the worm 17. A lifting mechanism is installed on the lower surface of the bed 1. The screw 12 drives the positioning plate 13 to move inward and clamp and fix the two sides of the cemented carbide. While the positioning plate 13 is moving, it stretches the return spring 14 and raises the cemented carbide to a certain height by lifting the movable block 3. Then, the rotating rod 18 is rotated, which drives the worm 17 to rotate. The worm 17 drives the rotating block 11 to rotate through the worm gear 15. The rotating block 11 drives the positioning plate 13 and the clamped cemented carbide to flip over through the screw 12, eliminating the need for cumbersome disassembly and re-fixing for subsequent processing.

[0024] like Figure 1-4 As shown, the lifting mechanism includes a hydraulic cylinder 7, which is fixedly installed at the center of the lower surface of the bed 1. The output end of the hydraulic cylinder 7 is driven by a connecting plate 4, and the upper surface of the connecting plate 4 is fixedly connected to the bottom end of the guide rod 5. Guide rods 5 are symmetrically fixed on both sides of the lower surface of the bed 1. A stop block 6 is fixedly installed at the bottom end of the guide rod 5, and the guide rod 5 is slidably connected to the connecting plate 4. When the cemented carbide needs to be flipped, the output end of the hydraulic cylinder 7 drives the connecting plate 4 to slide along the guide rod 5. The connecting plate 4 drives the movable block 3 to rise and fall stably, thereby ensuring the stable operation of the cemented carbide flipping.

[0025] like Figure 1-4 As shown, a processing table 8 is fixedly installed on one side of the upper surface of the bed 1. A collection box 10 is slidably installed in the inner cavity of the processing table 8. A filter hole 9 is opened on the upper surface of the processing table 8. The debris generated after processing falls into the collection box 10 through the filter hole 9 for storage.

[0026] like Figure 1-4 As shown, a first mounting block 19 is fixedly installed on the other side of the upper surface of the bed 1. A first motor 20 is fixedly installed on the outer wall of the first mounting block 19. A first lead screw is driven in the inner cavity of the first mounting block 19, and one end of the first lead screw is driven to the output end of the first motor 20. A first moving block 21 is driven on the surface of the first lead screw. A limit electric push rod 22 is fixedly installed at the top of the first moving block 21. A second mounting block 23 is driven at the top output end of the limit electric push rod 22. A second lead screw is driven in the inner cavity of the second mounting block 23. A second electric push rod is fixed on the outer wall of the second mounting block 23. The machine 24 has a second lead screw with one end connected to the output of the second motor 24. The surface of the second lead screw is provided with a second moving block 25. The bottom end of the second moving block 25 is fixedly provided with a processing device 26. The output of the first motor 20 drives the first lead screw to rotate. The first lead screw drives the limit electric push rod 22 and the second mounting block 23 to move laterally through the first moving block 21. The output of the second motor 24 drives the second lead screw to rotate. The second lead screw drives the second moving block 25 and the processing device 26 to move vertically. Under the extension and retraction of the limit electric push rod 22, it processes cemented carbide at different heights and positions.

[0027] Working principle: In use, the cemented carbide is first placed on the surface of the machining table 8. The screw 12 is rotated, causing the positioning plate 13 to move inward and clamp the cemented carbide on both sides. Simultaneously, the positioning plate 13 stretches the return spring 14. The output of the first motor 20 drives the first lead screw to rotate. The first lead screw, through the first moving block 21, drives the limit electric push rod 22 and the second mounting block 23 to move laterally. The output of the second motor 24 drives the second lead screw to rotate. The second lead screw drives the second moving block 25 and the machining equipment 26 to move vertically. Under the extension and retraction of the limit electric push rod 22, cemented carbide at different heights and positions is processed. After one side is processed, when processing other sides, the output end of the hydraulic cylinder 7 drives the connecting plate 4 to slide along the guide rod 5. The connecting plate 4 drives the movable block 3 to rise and fall stably. After the cemented carbide is raised to a certain height by lifting the movable block 3, the rotating rod 18 is rotated. The rotating rod 18 drives the worm gear 17 to rotate. The worm gear 17 drives the rotating block 11 to rotate through the worm wheel 15. The rotating block 11 drives the positioning plate 13 and the cemented carbide that has been clamped and fixed to flip over through the screw 12. There is no need for cumbersome disassembly and re-fixation for subsequent processing. The debris generated after processing falls into the collection box 10 through the filter hole 9 for storage. The overall structure is simple, the operation is convenient, the processing efficiency of the equipment is improved, and the application range is wider.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or equivalent variations to the above-disclosed technical content and apply them to other fields. However, any simple modifications, equivalent variations and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
