Description

Technical Field

[0001] This utility model relates to the technical field of diamond grinding block production, and in particular to a concentric clamp for grinding blocks used in diamond presses. Background Technology

[0002] Diamond grinding blocks are integral pieces formed under high temperature and pressure, primarily using diamond powder and various metal powders as binders. When producing diamond grinding blocks using a diamond press, the newly produced blocks are at a high temperature. They need to be removed from the mold and placed on a fixture to cool for a period before further processing. In the prior art, utility model patent application number 202222058632.6 discloses a concentric fixture for grinding blocks in a diamond press, mainly composed of a base plate, pads, and clamping blocks. In use, the diamond grinding blocks are removed from the diamond press and then clamped and fixed using the clamping blocks. However, the inventor believes that this fixture has the following problems: after the diamond grinding blocks are clamped and fixed, they only rely on their own heat dissipation for cooling, resulting in a slow cooling rate. This affects production progress when product delivery deadlines are tight, and the fixture is inconvenient to use. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a concentric clamp for diamond grinding blocks for diamond presses that promotes cooling of diamond grinding blocks by blowing cold air onto them, thereby increasing the cooling speed of the diamond grinding blocks. It is easy to use and highly practical.

[0004] This utility model discloses a concentric grinding block clamp for a diamond press, comprising a base plate, a housing, a door, and an exhaust pipe. The housing is mounted on the upper part of the base plate, and a chamber is provided inside the housing. The front end of the housing is open, and the door is mounted on the front end of the housing. The exhaust pipe is mounted on the upper part of the housing. It also includes a moving mechanism, a rotating mechanism, a clamping mechanism, and a blower mechanism. The rotating mechanism is mounted inside the chamber of the housing via the moving mechanism and has a forward and backward movement function. The clamping mechanism is mounted on the rotating mechanism and has a rotation function, as well as a clamping and fixing function. The blower... The output end of the blower mechanism is located inside the chamber of the housing. The blower mechanism has the function of blowing cold air. After the diamond grinding blocks are produced on the diamond press, the diamond grinding blocks are placed on the clamping mechanism and clamped and fixed. Then, the blower mechanism blows cold air onto the diamond grinding blocks to promote cooling. After the diamond grinding blocks have cooled down to room temperature, they can be removed from the clamping mechanism for further processing. By blowing cold air onto the diamond grinding blocks, the blower mechanism promotes cooling and improves the cooling speed of the diamond grinding blocks. It is convenient to use and highly practical.

[0005] The moving mechanism includes a hydraulic cylinder, a push rod, a moving plate, and slide rails. The hydraulic cylinder is fixedly installed at the rear end of the housing. The front and rear ends of the push rod are installed on the housing, with the input end of the push rod connected to the output end of the hydraulic cylinder. The moving plate is fixedly installed at the front end of the push rod and slides back and forth on two sets of slide rails. A rotating mechanism is installed on the upper end of the moving plate, and both sets of slide rails are fixedly installed inside the housing. When diamond grinding blocks need to be placed or removed from the clamping mechanism, the housing door is opened, and then the hydraulic cylinder is opened. The hydraulic cylinder pushes the moving plate forward via the push rod, and the moving plate drives the rotating mechanism and the clamping mechanism to move forward, causing the clamping mechanism to move out of the housing. Afterward, the operator can place or remove diamond grinding blocks from the clamping mechanism on the outside of the housing, thus facilitating the placement and removal of diamond grinding blocks.

[0006] The rotating mechanism includes an electric turntable, a rotating shaft, and a turntable. The electric turntable is fixedly installed on the upper end of the moving plate, the rotating shaft is installed on the rotating end of the electric turntable, the turntable is fixedly installed on the rotating shaft, and the clamping mechanism is installed on the turntable. When cold air is blown onto the diamond grinding block on the clamping mechanism by the blower mechanism, the electric turntable is turned on. The electric turntable rotates through the rotating shaft, and the turntable rotates the diamond grinding block through the clamping mechanism. During the rotation, the diamond grinding block comes into uniform contact with the cold air blown out by the blower mechanism, resulting in more uniform cooling of the diamond grinding block.

[0007] The clamping mechanism includes multiple rotating shafts, multiple three-jaw chucks, multiple gears, gear rings, and support rods. The rotating shafts are rotatably mounted on a turntable and are evenly distributed around their axes. The three-jaw chucks are fixedly mounted on the upper ends of the rotating shafts, and the gears are fixedly mounted on the lower ends of the rotating shafts. All gears mesh with gear rings, which are coaxial with the rotating shafts. The gear rings are fixedly mounted on a movable plate via support rods. When cooling the diamond grinding blocks, the multiple diamond grinding blocks are clamped and fixed by the three-jaw chucks, and then the mechanism is opened. The electric turntable rotates via a rotating shaft, which in turn drives multiple rotating shafts to rotate around the shaft. Simultaneously, these rotating shafts drive multiple gears to rotate around the shaft. Because the gears mesh with the gear rings, they also rotate on their own axis while rotating around the shaft. Therefore, the rotating shaft drives the three-jaw chuck to rotate around the shaft while simultaneously rotating on its own axis. This causes multiple diamond grinding blocks to rotate around the shaft and rotate on their own axis, ensuring that the diamond grinding blocks come into even contact with the cold air blown out by the blower, resulting in uniform cooling of the diamond grinding blocks. It is convenient to use and highly practical.

[0008] The blower mechanism includes a blower pipe, an air supply pipe, a cooler, an air inlet pipe, and a filter mechanism. The blower pipe is fixedly installed inside the housing and is located on the left side of multiple three-jaw chucks. Multiple air outlets are provided on the blower pipe. The input end of the blower pipe is connected to the cooler via the air supply pipe. The cooler is fixedly installed on the housing, and its input end is connected to the air inlet pipe. The input end of the air inlet pipe is connected to the filter mechanism, which has a filtering function. When cooling the diamond grinding blocks, the cooler is turned on, allowing outside air to enter the air inlet pipe after being filtered by the filter mechanism. The air then enters the cooler for cooling, and the cooled air enters the blower pipe via the air supply pipe. Finally, the cooled air is blown onto the diamond grinding blocks through the blower pipe, thus cooling the diamond grinding blocks and improving their heat dissipation effect.

[0009] Preferably, the filtration mechanism includes a filter cartridge, a support frame, and a filter plate. The filter cartridge is fixedly mounted on the base plate via the support frame. A cavity is provided inside the filter cartridge, with the lower end of the cavity being an opening. The filter plate is fixedly mounted inside the cavity of the filter cartridge. The input end of the air inlet pipe communicates with the cavity of the filter cartridge and is located above the filter plate. A valve is provided on the air inlet pipe. When the air cooler is turned on, outside air enters the filter cartridge through the lower end of the filter cartridge. After being filtered by the filter plate, the air enters the air inlet pipe. The filtration of the air by the filter plate reduces solid impurities in the air, preventing solid impurities from being blown onto the high-temperature diamond grinding blocks, thus improving reliability.

[0010] Preferably, the system also includes a water tank, a water pump, a water supply pipe, and a spray pipe. The water tank is fixedly installed on the base plate and located below the filter cartridge. The input end of the water pump is connected to the water tank, and the output end of the water pump is connected to the spray pipe through the water supply pipe. The spray pipe is fixedly installed at the upper end of the filter cartridge cavity, and the output end of the spray pipe is equipped with multiple sets of nozzles. A valve is installed on the water supply pipe, and the upper end of the water tank is set as an opening. When it is necessary to clean solid impurities on the filter plate, the water pump is turned on, so that the water in the water tank enters the spray pipe through the water pump and the spray pipe in sequence. Then, the water is sprayed onto the filter plate through the spray pipe, washing away the solid impurities attached to the lower end of the filter plate. This facilitates the rinsing of the filter plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by blowing cold air onto the diamond grinding block, the cooling of the diamond grinding block is promoted, the cooling speed of the diamond grinding block is improved, and it is convenient to use and highly practical.

Detailed Implementation

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0020] Example 1

[0021] like Figures 1 to 6The concentric clamp for diamond grinding blocks of this utility model includes a base plate 1, a housing 2, a door 3, an exhaust pipe 4, a moving mechanism, a rotating mechanism, a clamping mechanism, and a blower mechanism. The housing 2 is installed on the upper end of the base plate 1, and a chamber is provided inside the housing 2. The front end of the housing 2 is set as an opening. The door 3 is installed on the front end of the housing 2. The exhaust pipe 4 is installed on the upper part of the housing 2. The rotating mechanism is installed in the chamber of the housing 2 through the moving mechanism. The moving mechanism has the function of moving back and forth. The clamping mechanism is installed on the rotating mechanism. The rotating mechanism has the function of rotating. The clamping mechanism has the function of clamping and fixing. The output end of the blower mechanism is... Inside the chamber of housing 2, the blower mechanism has the function of blowing cold air. After the diamond grinding block 28 is produced on the diamond press, the diamond grinding block 28 is placed on the clamping mechanism and clamped and fixed. Then, the blower mechanism blows cold air onto the diamond grinding block 28 to promote the cooling of the diamond grinding block 28. After the diamond grinding block 28 cools down to room temperature, it is removed from the clamping mechanism and further processing can be carried out. By blowing cold air onto the diamond grinding block 28, the cooling of the diamond grinding block 28 is promoted, the cooling speed of the diamond grinding block 28 is improved, and it is convenient to use and highly practical.

[0022] like Figure 1 and Figure 5 The moving mechanism includes a hydraulic cylinder 5, a push rod 6, a moving plate 7, and slide rails 8. The hydraulic cylinder 5 is fixedly installed at the rear end of the housing 2. The front and rear ends of the push rod 6 are installed on the housing 2, and the input end of the push rod 6 is connected to the output end of the hydraulic cylinder 5. The moving plate 7 is fixedly installed at the front end of the push rod 6 and is slidably installed on two sets of slide rails 8. The rotating mechanism is installed on the upper end of the moving plate 7, and both sets of slide rails 8 are fixedly installed in the cavity of the housing 2. When it is necessary to pick up or put down the diamond grinding block 28 on the clamping mechanism, the housing door 3 is opened, and then the hydraulic cylinder 5 is opened. The hydraulic cylinder 5 moves the moving plate 7 forward through the push rod 6. The moving plate 7 drives the rotating mechanism and the clamping mechanism to move forward, so that the clamping mechanism moves out of the housing 2. Then, the operator can pick up or put down the diamond grinding block 28 on the clamping mechanism on the outside of the housing 2. This facilitates the picking up and putting down of the diamond grinding block 28.

[0023] like Figure 3 and Figure 4 The rotating mechanism includes an electric turntable 9, a rotating shaft 10, and a turntable 11. The electric turntable 9 is fixedly installed on the upper end of the movable plate 7. The rotating shaft 10 is installed on the rotating end of the electric turntable 9. The turntable 11 is fixedly installed on the rotating shaft 10. The clamping mechanism is installed on the turntable 11. When cold air is blown onto the diamond grinding block 28 on the clamping mechanism by the blower mechanism, the electric turntable 9 is turned on. The electric turntable 9 causes the turntable 11 to rotate through the rotating shaft 10. The turntable 11 causes the diamond grinding block 28 to rotate through the clamping mechanism. During the rotation, the diamond grinding block 28 comes into uniform contact with the cold air blown out by the blower mechanism, resulting in more uniform cooling of the diamond grinding block 28.

[0024] like Figure 3 and Figure 4 The clamping mechanism includes multiple rotating shafts 12, multiple three-jaw chucks 13, multiple gears 14, gear rings 15, and support rods 16. The multiple rotating shafts 12 are rotatably mounted on the turntable 11, and are evenly distributed circumferentially around the axis of the rotating shaft 10. The multiple three-jaw chucks 13 are respectively fixedly mounted on the upper ends of the multiple sets of rotating shafts 12. The multiple gears 14 are respectively fixedly mounted on the lower ends of the multiple rotating shafts 12, and all gears 14 mesh with gear rings 15. The gear rings 15 are coaxial with the rotating shafts 10 and are fixedly mounted on the moving plate 7 via the support rods 16. When cooling the diamond grinding blocks 28, the multiple diamond grinding blocks 28 are clamped and fixed by the multiple three-jaw chucks 13, and then... When the electric turntable 9 is turned on, the electric turntable 9 rotates the turntable 11 via the rotating shaft 10. The turntable 11 drives multiple rotating shafts 12 to rotate around the rotating shaft 10. At the same time, the multiple rotating shafts 12 drive multiple gears 14 to rotate around the rotating shaft 10. Since the gears 14 mesh with the gear ring 15, the gears 14 will rotate on their own axis while rotating around the rotating shaft 10. Therefore, the rotating shaft 12 drives the three-jaw chuck 13 to rotate around the rotating shaft 10 and also rotates on its own axis. This causes the multiple diamond grinding blocks 28 to rotate around the rotating shaft 10 and rotate on their own axis at the same time, so that the multiple diamond grinding blocks 28 can come into even contact with the cold air blown out by the blower, and cool down the multiple diamond grinding blocks 28 evenly. It is convenient to use and highly practical.

[0025] like Figure 3 and Figure 6 The blower mechanism includes a blower pipe 17, an air supply pipe 18, a cooler 19, an air inlet pipe 20, and a filter mechanism. The blower pipe 17 is fixedly installed in the cavity of the housing 2, located to the left of multiple three-jaw chucks 13. Multiple air outlets are provided on the blower pipe 17. The input end of the blower pipe 17 is connected to the cooler 19 via the air supply pipe 18. The cooler 19 is fixedly installed on the housing 2, and its input end is connected to the air inlet pipe 20. The input end of the air inlet pipe 20 is connected to... The filter mechanism is connected and has a filtering function. When cooling the diamond grinding block 28, the air cooler 19 is turned on, so that the outside air enters the air intake pipe 20 after being filtered by the filter mechanism. Then the air enters the air cooler 19 for cooling. After that, the cold air enters the air blowing pipe 17 through the air supply pipe 18. Then the cold air is blown onto the diamond grinding block 28 through the air blowing pipe 17, which can dissipate heat and cool the diamond grinding block 28. This improves the heat dissipation effect of the diamond grinding block 28.

[0026] Example 2

[0027] like Figure 6Based on Example 1, a water tank 24, a water pump 25, a water supply pipe 26, and a spray pipe 27 are added. The water tank 24 is fixedly installed on the base plate 1 and is located below the filter cartridge 21. The input end of the water pump 25 is connected to the water tank 24, and the output end of the water pump 25 is connected to the spray pipe 27 through the water supply pipe 26. The spray pipe 27 is fixedly installed at the upper end of the cavity of the filter cartridge 21, and the output end of the spray pipe 27 is equipped with multiple sets of nozzles. A valve is installed on the water supply pipe 26, and the upper end of the water tank 24 is set as an opening. When it is necessary to clean the solid impurities on the filter plate 23, the water pump 25 is turned on, so that the water in the water tank 24 enters the spray pipe 27 through the water pump 25 and the spray pipe 27 in sequence. Then the water is sprayed onto the filter plate 23 through the spray pipe 27 to wash away the solid impurities attached to the lower end of the filter plate 23. This facilitates the rinsing of the filter plate 23.

[0028] The hydraulic cylinder 5, electric turntable 9, three-jaw chuck 13, air cooler 19, filter plate 23, and water pump 25 of the diamond press concentric clamping fixture are all commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
