Description

Technical Field

[0001] The utility model relates to the technical field of numerical control grinding machines, and particularly relates to a positioning and pushing device for a numerical control grinding machine. Background Technique

[0002] A numerical control grinding machine is a machine tool that grinds the surface of a workpiece by using a grinding tool through numerical control technology. Most grinding machines use a high-speed rotating grinding wheel for grinding, and a small number use other grinding tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, abrasive belt grinding machines, grinding machines, and polishing machines.

[0003] After retrieval, the Chinese patent publication number: CN220839658U discloses a positioning and pushing device for a numerical control grinding machine, which includes a mounting plate. A cylinder is fixedly installed on the mounting plate. A cylinder rod is arranged on the cylinder. The cylinder rod is slidably connected in the mounting plate. A connecting sleeve is fixedly connected to the cylinder rod. A guiding mechanism is arranged on the connecting sleeve. A positioning mechanism is arranged in the connecting sleeve. A workpiece is in contact with the connecting sleeve. By designing components such as a screw rod, a rotating plate, a handle, an annular sleeve, a bolt, and an annular groove, when the screw rod is rotated, the screw rod rotates and has a threaded movement with the connecting sleeve. The rotation of the screw rod drives components such as the annular sleeve to move. The movement of the annular sleeve drives the clamping block to move. The movement of the clamping block contacts the workpiece, so that the workpiece is positioned, preventing the workpiece on the device from falling. Although this application can avoid the possible falling of the workpiece on the device, and when the cylinder rod on the device is used, the device has no guiding mechanism, and the cylinder rod is inconvenient to be guided, resulting in the possible deviation of the work on the device during movement. However, during the process of pushing the material, the material cannot be quantitatively transported, resulting in a large difference in the size, weight, etc. of the processed products, generating defects, thereby increasing the cost.

[0023] Embodiment:

[0024] Please refer to Figures 1 - 3 , this embodiment provides a positioning and material pushing device for a numerical control grinding machine, including an installation structure 1 and a material pushing structure 2. The material pushing structure 2 is installed on the top of the installation structure 1; the material pushing structure 2 is composed of a material pushing seat 21 and a metering device 22. One side of the material pushing structure 2 is installed with a telescopic rod 23, the other side of the telescopic rod 23 is installed with a sleeve 24. The bottom of the material pushing structure 2 is installed with an insertion block 212. A limiting groove 211 is opened on the side of the material pushing structure 2 away from the telescopic rod 23. The metering device 22 is installed inside the limiting groove 211. The metering device 22 is composed of a mounting seat 221 and a metering baffle 222. Metering baffles 222 are installed on both sides of the top of the mounting seat 221. A threaded adjusting rod 223 is inserted at the bottom between the metering baffles 222. An adjusting knob 224 is installed on the outer side wall of the mounting seat 221. By rotating the knob, the threaded adjusting rod 223 can be rotated, so as to control the two metering baffles 222 to approach or move away from each other. When the two metering baffles 222 approach each other, the internal space will be reduced, thereby reducing the amount of material pushed by the material pushing seat 21. On the contrary, when the two metering baffles 222 move away from each other, the internal space will be increased, thereby increasing the amount of material pushed by the material pushing seat 21.

[0025] In this embodiment, as Figure 1As shown, the installation structure 1 is composed of a base 11 and a fixing plate 12. One side of the top of the base 11 is provided with a fixing plate 12. A groove 112 is opened on the side of the base 11 away from the fixing plate 12, and a fixing groove 111 is opened on the top of the base 11. A driving cylinder 13 is installed on the outer side of the fixing plate 12, which can drive the telescopic rod 23 to expand and contract in the sleeve 24 through the driving cylinder 13, so as to control the left and right movement of the pushing seat 21 in the fixing groove 111 on the top of the base 11, thereby pushing the material.

[0026] In this embodiment, as Figures 1 - 2 , the insertion block 212 is inserted into the inside of the fixing groove 111, and a compression spring 214 that cooperates with the fixing groove 111 is installed on one side of the insertion block 212. When the driving cylinder 13 drives the telescopic rod 23 to expand and contract and push, the compression spring 214 can improve the pushing efficiency of the pushing seat through the rebounding force, thereby saving a large amount of costs.

[0027] In this embodiment, as Figure 1 and Figure 3 , the threaded adjusting rod 223 penetrates through the bottoms of the two quantitative baffles 222, and the adjusting knob 224 is in transmission connection with the threaded adjusting rod 223. By rotating the adjusting knob 224, the threaded adjusting rod 223 can be driven to rotate, so as to control the approach and separation of the two quantitative baffles 222.

[0028] In this embodiment, as Figures 1 - 3 , insertion slots 213 are opened on both sides of the inner side wall of the limiting slot 211 where the pushing structure 2 is located. One end of the quantitative baffle 222 is inserted into the inside of the insertion slot 213. The quantitative device 22 can be disassembled through the insertion slot 213 to repair or replace the quantitative device 22, so as to ensure the accuracy of the quantification of the quantitative device 22.

[0029] In this embodiment, as Figure 1 , the telescopic rod 23 is inserted into the inside of the sleeve 24, and one end of the sleeve 24 is installed on the side wall of the fixing plate 12 away from the driving cylinder 13, which can make the telescopic rod 23 drive the pushing seat 21 to move more stably.

[0030] In this embodiment, as Figure 1 , the output end of the driving cylinder 13 is in transmission connection with the telescopic rod 23. The driving cylinder 13 is used to drive the telescopic rod 23 to expand and contract in the sleeve 24, so as to control the movement of the pushing seat 21.

[0031] Working principle: By driving the cylinder 13 to drive the telescopic rod 23 to expand and contract in the sleeve 24, the movement of the material pushing seat 21 is controlled. When the driving cylinder 13 drives the telescopic rod 23 to expand and contract and push in the sleeve 24, the compression spring 214 can improve the pushing efficiency of the pushing seat through the rebound force, thereby saving a large amount of costs. By rotating the rotating knob, the threaded adjusting rod 223 is rotated, thereby controlling the two quantitative baffles 222 to approach or move away from each other. When the two quantitative baffles 222 approach each other, the internal space will be reduced, thereby reducing the amount of material pushed by the material pushing seat 21. On the contrary, when the two quantitative baffles 222 move away from each other, the internal space will be increased, thereby increasing the amount of material pushed by the material pushing seat 21. The quantitative device 22 can be disassembled through the insertion slot 213 for maintenance or replacement of the quantitative device 22, so as to ensure the accuracy of the quantification of the quantitative device 22. The structure of this device is simple, easy to use and has high practicability.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiment is a preferred implementation scheme of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
