Technical Field

[0001] This utility model belongs to the field of cutting machine technology, specifically relating to a cutting machine clamping mechanism. Background Technology

[0002] A cutting machine is a device used for precise material processing. It can cut various materials, and its main functions include cutting, trimming, and slicing. It features high cutting efficiency and good cut quality. To better ensure the cutting effect, a clamping mechanism is used to hold the material to be cut, ensuring stability and accuracy. However, common clamping mechanisms on the market cannot guarantee a secure clamping effect; excessive tightness or looseness will affect the cutting result. Some clamping mechanisms use single-sided clamping or cannot be adjusted according to actual needs.

[0003] In summary, existing technologies have the following drawbacks: they cannot ensure the clamping effect, which affects the cutting effect; the stability of unilateral clamping is poor; and they cannot be adjusted according to the cutting material, resulting in poor flexibility. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a clamping mechanism for a cutting machine, which can solve the problems of existing technologies that cannot ensure the clamping effect, affecting the cutting effect, and have poor stability of unilateral clamping, as well as poor flexibility in adjusting according to the material being cut. This utility model provides a clamping mechanism for a cutting machine, which includes a worktable with sliding grooves on both sides. Multiple through holes are located inside the sliding grooves. Two sets of clamping structures are provided on the two sliding grooves. Each set of clamping structures is connected by a connecting structure. A pressure sensor is provided inside the clamping block of each clamping structure. Each pressure sensor is connected to a controller on the side of the worktable via a circuit board inside the worktable. A rotating block is located outside the clamping structure. The rotating block is connected to a slider via a telescopic spring column in the middle. Spiral columns on both sides pass through through holes on both sides of the slider and are adapted to the through holes inside the sliding grooves and the fixed column below the power structure of the clamping structure. The power structure is connected to the circuit board.

[0006] Optionally, one side of the power structure is connected to the slider via a fixed block, and the other side is connected to the clamping block via a telescopic column.

[0007] Optionally, a fixing groove block is welded onto the clamping block, and the fixing groove block is a U-shaped fixing block with its opening facing downwards.

[0008] Optionally, the connecting structure has side U-shaped connecting blocks on both sides that are adapted to the fixing slot block, and the connecting structure and the connecting blocks are detachably connected.

[0009] Optionally, the connecting structure is an elastic rope or a rubber block.

[0010] Optionally, the power structure is an electric actuator.

[0011] Optionally, the workbench is provided with a support frame at its bottom.

[0012] In summary, this utility model has at least one of the following beneficial effects:

[0013] This invention employs a pressure sensor to monitor the clamping pressure in real time, a power structure to control the clamping force, and a controller to set the clamping range and operate the power structure to ensure that the clamping force is within the preset range. This avoids excessive pressure that could damage the object to be cut, and also avoids inaccurate cutting caused by misalignment during the cutting process due to insufficient pressure.

[0014] This invention employs two sets of cutting structures, both of which can move on the worktable through the interaction of slides and sliders. This avoids the poor stability of single-sided clamping and solves the problem of not being able to adjust according to the material being cut. The connection structure allows the object to be cut to be fixed longitudinally, further ensuring the stability of the mechanism. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1-4 This utility model will be described in further detail below.

[0022] Example 1, refer to Figure 1-4 In this embodiment, the problem that the existing technology cannot ensure the clamping effect, which affects the cutting effect, has poor stability of unilateral clamping, and has poor flexibility in adjusting according to the cutting material is addressed. This utility model discloses a clamping mechanism for a cutting machine, including a worktable 5, with sliding grooves 3 on both sides of the worktable 5, and multiple through holes on the inner side of the sliding grooves 3. Two sets of clamping structures 1 are provided on the two sliding grooves 3, and each set of clamping structures 1 is connected in the middle by a connecting structure 4. A pressure sensor 15 is provided on the inner side of the clamping block 13 of each clamping structure 1. Each pressure sensor 15 is connected to a controller 16 on the side of the worktable 5 through a circuit board 2 inside the worktable 5. A rotating block 6 is located on the outer side of the clamping structure 1. The rotating block 6 is connected to a slider 8 through a telescopic spring column 7 in the middle. Spiral columns 9 on both sides pass through the through holes on both sides of the slider 8 and are adapted to the through holes on the inner side of the sliding grooves 3 and the fixed column 11 below the power structure 10 of the clamping structure 1. The power structure 10 is connected to the circuit board 2. A support frame 17 is provided at the bottom of the worktable 5. One side of the power structure 10 is connected to the slider 8 through a fixed block, and the other side is connected to the clamping block 13 through a telescopic column 12. The power structure 10 is an electric push rod.

[0023] The two sets of clamping structures 1 overcome the instability problem of traditional single-sided clamping. The two sets of clamping structures 1 can move left and right on the slide 3 to meet the cutting requirements of different lengths. The spiral columns 9 on both sides of the bottom of the spiral block 6 pass through the through holes on both sides of the slider 8 and are connected to the through holes and the fixing column 11 on the inside of the slide 3. This can fix the position of the clamping structure 1 and prevent the slider 8 from moving on the slide 3 during the cutting process, which would affect the cutting effect. There is a pressure sensor 15 on the inside of the clamping block 13. The pressure sensor 15 and the power structure 10 are connected to the controller 16 through the circuit board 2. The controller 16 controls the movement of the power structure 10 by the specified pressure, so as to avoid the clamping effect being affected by too much or too little pressure.

[0024] A fixing groove block 14 is welded onto the clamping block 13. The fixing groove block 14 is a U-shaped fixing block with its opening facing downwards. There are side U-shaped connecting blocks 18 on both sides of the connecting structure 4 that are adapted to the fixing groove block 14. The connecting structure 4 and the connecting blocks 18 are detachably connected. The connecting structure 4 is an elastic rope or a rubber block.

[0025] The connection structure 4 is better connected between the two clamping blocks 13 by the snap-fit ​​of the fixing slot block 14 and the connecting block 18, which limits the longitudinal height of the item to be cut and further ensures stability. The connecting structure 4 is an elastic rope or rubber block with a certain degree of extensibility, which makes the universality of this mechanism stronger.

[0026] Specific implementation principle: When using this utility model, first determine the position of the clamping structure 1 according to the length of the item to be cut, rotate the rotating block 6, and the telescopic spring column 7 compresses and drives the spiral columns 9 on both sides to enter the fixed column 11 to complete the fixation. Place the item to be cut between the two sets of clamping blocks 13, and fix it above using the connecting structure 4. Adjust the pressure value on the controller 16 to control the power structure 10 to drive the telescopic column 12 to move the clamping blocks 13 closer to each other. The pressure sensor 15 contacts the item to be cut and generates pressure. When the pressure reaches the preset pressure, the power structure 10 stops operating, achieving a stable fixing effect.

[0027] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
