[0032] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0033] In a numerical control device, a fixture tooling refers to a mechanical device used to fix and position workpieces. It usually consists of a clamping device and a supporting device. The clamping device can tightly fix the workpiece on the workbench, while the supporting device provides the necessary supporting force to ensure that the workpiece does not move or loosen during the machining process. The design of the fixture tooling aims to ensure machining accuracy, improve production efficiency, and ensure operation safety. They play a crucial role in machining, especially in a production environment that requires high precision and high efficiency. However, the current fixture tooling is very inconvenient to disassemble and assemble. All the pressure blocks need to be removed before clamping the product. Therefore, the clamping efficiency of the operator is low, and the clamping labor intensity is too high, resulting in a high labor cost. In addition, it also affects the overall efficiency of the numerical control device.

[0034] Based on this, please refer to Figure 1 and Figure 2 , the fixture tooling 1000 provided in the embodiments of the present utility model can effectively improve the above-mentioned technical problems. The fixture tooling 1000 can quickly install and disassemble the pressure block 300 and the cover plate 200, reduce the labor intensity of personnel, improve the clamping efficiency, thereby improving the production efficiency of the numerical control device processing and reducing the production cost.

[0035] Figure 1 is a schematic diagram of the fixture tooling 1000 provided in the embodiments of the present utility model; Figure 2 is an exploded schematic diagram of the fixture tooling 1000 provided in the embodiments of the present utility model, as shown in Figure 1 and Figure 2As shown, the fixture tool 1000 provided in this embodiment includes a fixture seat 100, a cover plate 200 and a pressing block 300. The fixture seat 100 is used to place the workpiece to be processed; the cover plate 200 is detachably connected to the fixture seat 100; the pressing block 300 is magnetically connected to the cover plate 200, and the pressing block 300 is located between the cover plate 200 and the fixture seat 100 when pressing the workpiece to be processed. When it is necessary to clamp the workpiece to be processed, the connection between the cover plate 200 and the fixture seat 100 is disconnected, and the cover plate 200 is removed. Because the pressing block 300 is magnetically connected to the cover plate 200, when the cover plate 200 is removed, the pressing block 300 can also be removed at the same time, which simplifies the operation and reduces the time for disassembling the tool. Then, the workpiece to be processed is placed on the fixture seat 100, the pressing block 300 presses the workpiece to be processed, and then the cover plate 200 is connected to the fixture seat 100, so that the pressing block 300 clamps the workpiece to be processed, thereby facilitating the CNC equipment to process the workpiece to be processed. By setting up a magnetic connection between the pressing block 300 and the cover plate 200, when the product needs to be disassembled and clamped, it is only necessary to disconnect the connection between the cover plate 200 and the fixture seat 100, and the pressing block 300 can be taken away while removing the cover plate 200, which can simplify the operation, effectively shorten the clamping time of the product, reduce the labor intensity of personnel, improve the production efficiency of processing, and reduce production costs.

[0036] Since the cover plate 200 and the pressing block 300 are connected by magnetic attraction, when clamping the workpiece to be processed, the pressing block 300 can be separated from the cover plate 200 and installed to clamp the workpiece separately, or the pressing block 300 and the cover plate 200 can be installed to clamp the workpiece at the same time, which is determined according to the actual operating conditions and is not limited here.

[0037] Please continue reading Figure 1 and Figure 2, the "detachable connection between the cover plate 200 and the fixture base 100" mentioned above. Specifically, in this embodiment, a first mounting hole 230 is provided on the cover plate 200, a second mounting hole 310 is provided on the pressing block 300, and a third mounting hole 120 is provided on the fixture base 100. The first mounting hole 230, the second mounting hole 310, and the third mounting hole 120 are correspondingly arranged; a threaded fastener 500 is passed through the first mounting hole 230, the second mounting hole 310, and the third mounting hole 120 to clamp and fix the cover plate 200, the pressing block 300, and the fixture base 100. The threaded fastener 500 can be a screw, a bolt, etc. The threaded fastener 500 in this embodiment is a pneumatic screwdriver quick-locking screw, which has a fast installation speed, high safety, anti-static, and low failure rate. The pneumatic actuator has a fast movement speed and can quickly and accurately tighten the screw, improving production efficiency. The pneumatic screwdriver has the characteristics of low noise, low vibration, and low temperature, and will not cause harm to the operator, thus improving work safety. Moreover, pneumatic tools can effectively prevent static electricity accumulation. In addition, pneumatic tools have a low failure rate, adopt high-quality materials and structures, and have a long service life and a low failure rate.

[0038] The "magnetic attraction connection between the pressing block 300 and the cover plate 200" mentioned above. Specifically, please refer to Figure 2 and Figure 3 , Figure 3 is a schematic diagram of the cover plate 200 provided in the embodiment of the present invention. In this embodiment, a mounting groove 210 is provided on the cover plate 200, and a magnetic attraction block 400 is arranged in the mounting groove 210.

In addition, magnets can also be arranged in both the cover plate 200 and the pressing block 300. The magnetic table of the cover plate 200 and the magnet of the pressing block 300 have opposite magnetic poles. Using the principle of opposite-sex attraction, the magnetic attraction connection between the cover plate 200 and the pressing block 300 can also be realized. Of course, other magnetic attraction methods can also be used to realize the connection between the cover plate 200 and the pressing block 300, which is determined according to the actual situation and cost and is not limited herein.

By providing multiple mounting grooves 210 and arranging at least one magnetic attraction block 400 in each mounting groove 210, the magnetic attraction force between the cover plate 200 and the pressing block 300 can be increased to ensure that when the cover plate 200 is removed, the pressing block 300 will not be separated from the cover plate 200, which is convenient to take out together, disconnect from the fixture base 100, so as to simplify the clamping operation and improve production efficiency.

[0040] Specifically, the number of the mounting grooves 210 in this embodiment is three, and the three mounting grooves 210 are distributed in a triangular shape. The number of the mounting grooves 210 in this embodiment can also be four, and the four mounting grooves 210 are distributed in a rectangular or square shape.

[0041] In order to facilitate disassembly and assembly and be able to press the workpiece tightly to ensure the stability of the magnetic attraction connection between the cover plate 200 and the pressing block 300, the number of the pressing blocks 300 in this embodiment is multiple, the multiple pressing blocks 300 are arranged at intervals, and the multiple pressing blocks 300 are all magnetically attracted to the cover plate 200. By setting multiple pressing blocks 300, the size of the pressing block 300 can be reduced, and the magnetic attraction force between the cover plate 200 and each pressing block 300 can be reduced. In order to ensure the stability of the magnetic attraction connection between the cover plate 200 and each pressing block 300, in this embodiment, the cover plate 200 is provided with multiple mounting grooves 210 for each pressing block 300, and at least one magnetic attraction block 400 is arranged in the mounting groove 210. Each group of mounting grooves 210 is correspondingly connected to one pressing block 300. The number of each group of mounting grooves 210 may be two, three, four or more, and is distributed in a diagonal shape, a triangular shape, a rectangular or square shape, etc. Of course, the pressing block 300 can also be designed as an integral block, which is determined according to the actual situation and is not limited herein.

[0044] A fixture tooling 1000 provided according to this embodiment has the following working principle:

[0045] When it is necessary to clamp the workpiece to be machined, the connection relationship between the cover plate 200 and the fixture base 100 is disconnected, and the cover plate 200 is removed. Since the briquette 300 and the cover plate 200 are magnetically connected, therefore, when the cover plate 200 is removed, the briquette 300 can also be taken off incidentally, which simplifies the operation and reduces the time for disassembling the tooling. Then the workpiece to be machined is placed on the fixture base 100, the briquette 300 presses the workpiece to be machined, and then the cover plate 200 is connected to the fixture base 100 to clamp the workpiece to be machined by the briquette 300, thereby facilitating the numerical control equipment to machine the workpiece to be machined. This fixture tooling 1000 can simplify the operation, effectively shorten the clamping time of the product, reduce the labor intensity of personnel, improve the production efficiency of machining, and reduce the production cost.

[0046] In summary, this fixture tooling 1000 includes a fixture base 100, a cover plate 200 and a briquette 300. The fixture base 100 is used to place the workpiece to be machined; the cover plate 200 is detachably connected to the fixture base 100; the briquette 300 is magnetically connected to the cover plate 200, and the briquette 300 is located between the cover plate 200 and the fixture base 100 when pressing the workpiece to be machined.
