Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0038] Example: Please refer to Figures 1 to 8 :

[0039] This invention proposes a filing device for tool processing, including a support and fixing component 1;

[0040] The support and fixing assembly 1 includes a support base 101 and a support frame 102. The support frame 102 is fixedly installed on the top of the support base 101, and a tool blank fixing fixture is installed inside the support base 101. A processing assembly 2 is installed at the bottom of the crossbar of the support frame 102.

[0041] The filing assembly 4 includes a tool clamping plate 401 and a movable filing plate 402. The tool clamping plate 401 is fixedly installed on the bottom of the movable filing plate 402, and a file is fixedly installed on the bottom of the tool clamping plate 401. The movable filing plate 402 is inserted into the bottom of the mounting shell 203.

[0042] The processing component 2 includes a pressure threaded rod 201, a positioning cylinder 202, and a mounting shell 203. The pressure threaded rod 201 is fixed to the middle of the cross frame of the support frame 102 by threaded connection, and the cylinder body of the positioning cylinder 202 is inserted into the cross frame of the support frame 102. The bottom end of the positioning cylinder 202 is fixedly installed on the top of the mounting shell 203. The mounting shell 203 is inserted into the cross frame of the support frame 102 by a top rail rod, and a drive component 3 is installed inside the mounting shell 203. The mounting shell 203 can control the balance of the file by the top rail rod.

[0043] The processing component 2 can control and position the filing pressure, balance and filing depth of the bottom file of the filing component 4, thereby ensuring the accuracy of the filing process and increasing the yield by 30%.

[0044] Furthermore, according to embodiments of the present invention, such as Figure 4 As shown, a filing plate 2011 is rotatably connected to the bottom of the pressure threaded rod 201. A pressure spring 2012 is provided at the bottom of the filing plate 2011, and the two ends of the pressure spring 2012 are fixedly connected to the bottom of the filing plate 2011 and the top of the mounting shell 203, respectively. In use, the pressure threaded rod 201 of the processing component 2 can control the filing pressure when the file is filed. When the pressure threaded rod 201 is rotated, the pressure threaded rod 201 can move up and down inside the crossbeam of the support frame 102, changing the position of the filing plate 2011, thereby changing the compression state of the pressure spring 2012, that is, changing the filing pressure during filing. It is flexible to adjust, convenient to use, and can adapt to the filing operation needs of different filing pressures.

[0045] Furthermore, according to embodiments of the present invention, such as Figure 4 As shown, the positioning cylinder 202 consists of two semi-circular cylinders. The outside of the positioning cylinder 202 is threaded, and a positioning screw block 2021 is screwed onto the outside of the cylinder of the positioning cylinder 202. In use, by rotating the positioning screw block 2021 on the outside of the positioning cylinder 202, the maximum descent height of the processing component 2 during filing can be controlled, thereby realizing the use requirement of precise positioning of filing depth, resulting in higher accuracy of filing and convenient operation.

[0046] The drive assembly 3 includes a drive motor 301, a compound gear 302 and a reversing gear 303. The drive motor 301 is fixedly installed inside the mounting housing 203, and the compound gear 302 and the reversing gear 303 are rotatably connected inside the mounting housing 203.

[0047] The drive motor 301 is electrically connected to an external power supply and control device. Its specific structure and working principle are existing mature technologies and will not be described in detail here.

[0048] The drive component 3 can drive the filing component 4 to automatically reciprocate and realize the automatic filing operation of the tool blank, which simplifies the operation process, greatly reduces the labor intensity of workers, and increases work efficiency by 40%.

[0049] Furthermore, according to embodiments of the present invention, such as Figure 5 As shown, the driver component 3 also includes:

[0050] Drive rod 304 is rotatably connected inside the mounting housing 203, and the top of the rod body of drive rod 304 is fixedly connected to the bottom of the rotating rod of drive motor 301;

[0051] The commutator block 305 is inserted into the outside of the drive rod 304;

[0052] The control gear 306 is inserted into the reversing block 305, and the control gear 306 is provided with a transmission protrusion 3061 inside. The drive rod 304 is provided with a transmission groove 3041 inside the rod body, and the transmission protrusion 3061 is inserted into the transmission groove 3041.

[0053] During use, the transmission protrusion 3061 of the control gear 306 can always obtain the transmission of the drive rod 304 through the transmission groove 3041, ensuring stable operation.

[0054] Furthermore, according to embodiments of the present invention, such as Figure 5 As shown, the compound gear 302 consists of a forward gear 321 and a reverse gear 322. Both the top and bottom of the compound gear 302 are equipped with transmission gears. The height of the transmission gear at the top of the forward gear 321 is higher than the height of the transmission gear at the top of the reverse gear 322 and the reversing gear 303. In use, the drive motor 301 can drive the filing assembly 4 to reciprocate, thus automating the filing operation. A control block 2031 is inserted into the inside of the mounting housing 203. The control block 2031 is an "I"-shaped block, and the inner side of the block has an inclined... A slanted control slot 20311 is provided, and a control rod 3051 is provided on the outer side of the reversing block 305. The control rod 3051 is inserted into the inside of the control slot 20311. When the control gear 306 is located at the top of the control slot 20311, the control gear 306 meshes with the transmission gear at the top of the positive gear 321, thereby enabling the control gear 306 to drive the positive gear 321 to rotate. A filing rack 4021 is provided on the side of the top of the movable file plate 402, and the filing rack 4021 meshes with the teeth of the transmission gear at the bottom of the compound gear 302. Figure 6 As shown, when the forward gear 321 rotates, the transmission gear at the bottom drives the filing assembly 4 to move forward through the filing rack 4021 to achieve automatic filing operation.

[0055] Furthermore, according to embodiments of the present invention, such as Figure 6As shown, the movable file plate 402 has reversing push rods 4022 on both sides of its top. In use, when the reversing push rods 4022 of the movable file plate 402 move forward to the end, they will press the control block 2031, causing the control block 2031 to move. When the control block 2031 moves, the control groove 20311 drives the reversing block 305 to move downward through the control rod 3051. When the reversing block 305 moves downward, it drives the control gear 306 to move downward synchronously. At this time, the control gear 306 loses its transmission with the forward gear 321. In the dynamic relationship, the forward gear 321 and the reverse gear 322 are located on both sides of the control gear 306, and the transmission gear at the top of the reverse gear 322 meshes with the teeth of the reversing gear 303. At this time, the control gear 306 and the reversing gear 303 drive the reverse gear 322 to rotate. At this time, the filing component 4 will move in the opposite direction, thereby realizing the function of the drive component 3 driving and controlling the reciprocating motion of the filing component 4 to achieve automated filing processing. The degree of automation is high, greatly reducing labor intensity and improving work efficiency.

[0056] Furthermore, according to embodiments of the present invention, such as Figure 4 As shown, positioning spring blocks are rotatably connected to the outer block of the control block 2031 and the exterior of the mounting shell 203, and a positioning top spring 2032 is provided between the two positioning spring blocks. The two ends of the positioning top spring 2032 are respectively fixedly connected to the interior of the two positioning spring blocks. In use, the positioning top spring 2032 can stably fix and limit the position of the control block 2031, thereby enabling the device to stably realize the automated filing process of the tool blank and use stably.

[0057] The specific usage and function of this embodiment: In this invention, the tool blank is fixed inside the device by the tool blank fixing clamp of the support base 101. Then, the pressure threaded rod 201 is rotated to lower the processing component 2 to the top surface of the tool blank. The pressure threaded rod 201 is rotated to adjust the filing pressure. When the pressure threaded rod 201 is rotated, it can move up and down inside the crossbeam of the support frame 102, changing the position of the filing pressure plate 2011, thereby changing the compression state of the pressure top spring 2012, that is, changing the filing pressure during filing. Then, the filing depth is adjusted. By rotating the positioning block 2021 outside the positioning cylinder 202, the maximum descent height of the processing component 2 during filing can be controlled, thereby achieving the requirement of precise positioning of the filing depth. After adjustment, after turning on the power of the drive motor 301, the drive component 3 of the device can drive the filing component 4 to automatically perform filing operations on the tool blank. The drive motor 301 can drive the filing component 4 to reciprocate, realizing the automation of the filing operation. When the control gear 306 is located at the top of the control groove 20311, the control gear 306 meshes with the transmission gear at the top of the forward gear 321, thereby... At this time, the control gear 306 can drive the forward gear 321 to rotate. The transmission gear at the bottom of the forward gear 321 drives the filing assembly 4 to move forward through the filing rack 4021 to achieve automatic filing operation. When the reversing push rod 4022 of the moving filing plate 402 moves forward to the end, it will press the control block 2031 and drive the control block 2031 to move. When the control block 2031 moves, the control groove 20311 drives the reversing block 305 to move downward through the control rod 3051. When the reversing block 305 moves downward, it drives the control gear 306 to move downward synchronously. At this time, the control gear 306 loses its rotation. The drive mechanism is connected to the forward gear 321, and at this time, the control gear 306 and the reversing gear 303 drive the reverse gear 322 to rotate. At this time, the filing component 4 will move in the opposite direction, thus realizing the function of the drive component 3 driving and controlling the reciprocating motion of the filing component 4 to achieve automated filing processing. The degree of automation is high, and the positioning top spring 2032 can stably fix and limit the use position of the control block 2031, so that the device can stably realize automated filing processing of the tool blank. After the processing is completed, the power of the drive motor 301 is turned off and the tool blank is removed.

[0058] Finally, it should be noted that when describing the position of each component and the mating relationship between them, the present invention usually uses one or a pair of components as examples. However, those skilled in the art should understand that such positions, mating relationships, etc., are also applicable to other components or other pairs of components.
