[0004] Although the above scheme can place sheet metal parts, when the length of the sheet metal parts exceeds the preset range of the cutting table during sheet metal cutting, the device cannot support the sheet metal, and the sheet metal parts are prone to move during the cutting process, resulting in cutting deviations. At the same time, the device lacks the function of movement, and it is not easy for operators with less strength to move it, affecting its use. Therefore, it does not meet existing needs. In this regard, we propose a multifunctional sheet metal cutting auxiliary frame. Utility Model Content

[0005] The purpose of the present utility model is to provide a multifunctional sheet metal cutting auxiliary frame to solve the problem that the cutting auxiliary frame proposed in the above background technology is inconvenient to support and limit the sheet metal when the length of the sheet metal exceeds the preset range of the cutting table, affecting the cutting effect and inconvenient to move.

[0006] To achieve the above object, the present invention provides the following technical solution: a multifunctional sheet metal cutting auxiliary frame, comprising a base, a support seat is provided above the base, and a lifting cavity is opened on the upper side of the interior of the base;

[0007] It also includes universal wheels, which are installed at the four corners of the lower end of the base. Fixed blocks are provided on one side of the front and rear ends of the base. The interior of the fixed blocks are threadedly connected to a rotating rod, and both ends of the rotating rod extend to the outside of the fixed blocks;

[0008] The lifting mechanism further comprises a transmission chamber, which is provided below the lifting chamber, wherein a second rotating shaft is rotatably provided at the lower end of the transmission chamber, a threaded rod is rotatably provided at the lower end of the lifting chamber, and one end of each threaded rod is connected to the second rotating shaft, an external thread of the threaded rod is connected to a lifting block, and an upper end of the lifting block is connected to a support seat;

[0009] It also includes a slide groove, which is arranged on one side of the upper end of the support seat, and there are two slide grooves. Two clamping blocks are slidably arranged on one side of the upper end of the support seat. The lower ends of the clamping blocks extend into the interior of the slide groove, and the clamping blocks are slidably matched with the slide groove.

[0010] Preferably, a motor is provided on one side of the transmission cavity, and a first rotating shaft is provided at the output end of the motor through a coupling. Bevel gears are provided on one end of the first rotating shaft and the outer wall of the second rotating shaft, and the bevel gears are meshed and connected with each other.

[0011] Preferably, the upper end of the rotating rod is provided with a knob, and the lower end of the rotating rod is provided with a rubber anti-sliding block.

[0012] Preferably, first guide rods are welded on both sides of the interior of the lifting cavity, the first guide rods both pass through the lifting block, and the first guide rods both slide in conjunction with the lifting block.

[0013] Preferably, a second guide rod is welded inside the slide groove, one end of the second guide rod passes through one end of the clamping block located inside the slide groove, and the second guide rod is slidably matched with the clamping block.

[0014] Preferably, the front and rear sides of the exterior of the second guide rod are sleeved with return springs, one end of the return spring is connected to the clamping block, and the other end of the return spring is connected to the sliding groove.

[0015] Preferably, two telescopic rods are provided on one side of the upper end of the base, and the output ends of the telescopic rods are connected to the support seat.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The utility model is provided with a support seat above the base. When the length of the sheet metal part exceeds the preset range of the cutting table, the excess part can be placed on the support seat. By pulling the clamping block, it can slide inside the sliding block. When the hand is released, the two clamping blocks can move toward each other under the elastic action of the reset spring, so that the sheet metal part can be clamped and fixed in the middle position. The support seat provides a support point for the excess part of the sheet metal part, and the clamping block ensures that the position of the excess part of the sheet metal part will not change, thereby ensuring the accuracy of cutting. The overall operation is simple and easy to use.

[0018] 2. The utility model installs universal wheels at the four corners of the lower end of the base. The base can be pushed by the handle on one side of the base. It can be moved very conveniently under the rolling of the universal wheels, thereby improving portability. When moved to the sheet metal cutting equipment, the operator can turn the knob, and the knob will drive the rubber anti-sliding block to move downward through the rotating rod, so that the rubber anti-sliding block is squeezed and fits the ground. The friction with the ground is increased by the rubber anti-sliding block, thereby ensuring stability during use and avoiding affecting the cutting of sheet metal parts.

[0019] 3. The utility model opens a lifting cavity inside the base. Since different sheet metal cutting equipment has different models and different cutting positions, by starting the motor, the motor will rotate one of the bevel gears through the first device. Under the meshing transmission between the bevel gears, the second rotating shaft can drive the threaded rod to rotate. The rotation of the threaded rod will cause the lifting block to rise vertically, thereby driving the height of the support base to change. The telescopic rod ensures the stability of the support base, and can adapt to sheet metal cutting equipment of different heights, thereby increasing applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-4 The utility model provides a technical solution: a multifunctional sheet metal cutting auxiliary frame, comprising a base 1, a support seat 16 is provided above the base 1, and a lifting cavity 7 is opened on the upper side of the interior of the base 1;

[0027] It also includes universal wheels 2, which are installed at the four corners of the lower end of the base 1. A fixing block 3 is provided on one side of the front and rear ends of the base 1. The interior of the fixing block 3 is threadedly connected to a rotating rod 4, and both ends of the rotating rod 4 extend to the outside of the fixing block 3;

[0028] The transmission chamber 8 is provided below the lifting chamber 7. A second rotating shaft 13 is rotatably provided at the lower end of the transmission chamber 8. A threaded rod 14 is rotatably provided at the lower end of the lifting chamber 7. One end of each threaded rod 14 is connected to the second rotating shaft 13. The outer surface of the threaded rod 14 is threadedly connected to a lifting block 9. The upper end of the lifting block 9 is connected to a support seat 16.

[0029] It also includes a slide groove 18, which is arranged on one side of the upper end of the support seat 16, and there are two slide grooves 18. Two clamping blocks 21 are slidably arranged on one side of the upper end of the support seat 16. The lower ends of the clamping blocks 21 extend to the interior of the slide groove 18, and the clamping blocks 21 are slidably matched with the slide groove 18.

[0030] During use, the handle and universal wheel 2 of the base 1 can be used to conveniently move it to the side of the sheet metal cutting equipment. The knob 6 is rotated to drive the rotating rod 4 to drive the rubber anti-slider 5 to stick to the ground to enhance stability. After the motor 10 is started, the first rotating shaft 11 and the bevel gear 12 group are driven through the coupling, and the second rotating shaft 13 and the threaded rod 14 are synchronously driven to rotate, so that the lifting block 9 is vertically lifted and lowered along the first guide rod 15, and the support seat 16 is adjusted to the same height as the cutting table to support the sheet metal. The clamping block 21 slides along the slide groove 18 and is guided by the second guide rod 19. The reset spring 20 ensures consistent clamping force, and the excess part of the sheet metal is firmly clamped between the two clamping blocks 21, effectively preventing displacement during cutting and ensuring cutting accuracy.

[0031] See also Figure 2 A motor 10 is provided on one side of the transmission cavity 8, and a first rotating shaft 11 is provided on the output end of the motor 10 through a coupling. A bevel gear 12 is provided on one end of the first rotating shaft 11 and the outer wall of the second rotating shaft 13, and the bevel gears 12 are meshed and connected. The first rotating shaft 11 is directly driven by the motor 10, which simplifies the power transmission path and improves the transmission efficiency. The meshing connection between the bevel gears 12 realizes the smooth conversion and transmission of power, ensuring that the second rotating shaft 13 can rotate at a predetermined speed and direction, providing reliable power support for subsequent lifting operations;

[0032] See also Figure 1 and Figure 3, the upper end of the rotating rod 4 is provided with a knob 6, and the lower end of the rotating rod 4 is provided with a rubber anti-sliding block 5. The rubber anti-sliding block 5 can effectively increase the friction with the ground and prevent the device from sliding due to vibration or external force during the cutting process, thereby ensuring the stability and safety of the cutting operation. The design of the knob 6 makes it simple and quick to adjust the height of the rotating rod 4 and the rubber anti-sliding block 5, thereby improving the operating efficiency;

[0033] See also Figure 2 , first guide rods 15 are welded on both sides of the interior of the lifting cavity 7. The first guide rods 15 all pass through the lifting block 9, and the first guide rods 15 all slide with the lifting block 9. The first guide rods 15 provide a stable lifting track for the lifting block 9, ensuring the precise movement of the lifting block 9 in the vertical direction. The sliding fit design reduces the friction resistance of the lifting block 9 during movement, making the lifting action smoother;

[0034] See also Figure 4 A second guide rod 19 is welded inside the chute 18, one end of the second guide rod 19 passes through the end of the clamping block 21 located inside the chute 18, and the second guide rod 19 is slidably matched with the clamping block 21. The second guide rod 19 provides a precise moving path for the clamping block 21, ensuring that the clamping block 21 can move along a predetermined direction when clamping the sheet metal, thereby avoiding offset or dislocation during the clamping process;

[0035] See also Figure 4 , the front and rear sides of the second guide rod 19 are both sleeved with return springs 20, one end of the return spring 20 is connected to the clamping block 21, and the other end of the return spring 20 is connected to the slide groove 18. The return spring 20 provides the clamping block 21 with an automatic reset function. When the clamping block 21 is released, the return spring 20 can automatically push the clamping block 21 back to the initial position, which is convenient for the next clamping operation. At the same time, the return spring 20 also has a certain buffering effect, which can reduce the impact damage to the sheet metal during the clamping process;

[0036] See also Figure 1 and Figure 2 Two telescopic rods 17 are provided on one side of the upper end of the base 1, and the output ends of the telescopic rods 17 are connected to the support seat 16. The telescopic rods 17 can adjust the height of the support seat 16 according to actual needs, so that the support seat 16 can be adapted to cutting tables of different heights. The telescopic rods 17 also have a certain load-bearing capacity and stability, which can ensure that there will be no shaking or tilting when supporting the sheet metal, thereby ensuring the smooth progress of the cutting operation.

[0037] Working principle: When in use, grasp the handle on one side of the base 1 and apply external force. The universal wheel 2 can be used to move the device, which improves its portability. After moving to the sheet metal cutting equipment, turn the knob 6. The knob 6 will drive the rotating rod 4 to rotate, causing the rotating rod 4 to rotate downward, so that the rubber anti-slip block 5 can move down synchronously, so that the rubber anti-slip block 5 is squeezed and fits the ground, which can increase the friction with the ground, improve the overall stability, and avoid affecting the accuracy of sheet metal cutting. Start the motor 10, and the motor 10 will rotate the first rotating shaft 11 through the coupling. The first rotating shaft 11 will drive one of the bevel gears 12 to rotate synchronously. Since the bevel gear 12 is engaged with the other bevel gear 12, it will drive the other bevel gear 12 to rotate the second rotating shaft 13. The second rotating shaft 13 will drive the threaded rod 14 to rotate synchronously. The rotation of the threaded rod 14 will drive the lifting block 9 to rotate synchronously. Since the lifting block 9 is axially limited by the two first guide rods 15, the rotation of the lifting block 9 will be converted into The lifting block 9 drives the support base 16 to move synchronously with the vertical movement up and down, and the telescopic rod 17 ensures the stability of the support base 16 during the lifting and moving, and aligns the height of the support base 16 with the cutting table of the sheet metal cutting equipment, so that the part of the sheet metal that exceeds the cutting table can be placed on the upper end of the support base 16. The operator can grab the handle on one of the clamping blocks 21 and pull it, so that the clamping block 21 can slide inside the slide groove 18. The setting of the second guide rod 19 ensures that the movement of the clamping block 21 will not deviate. The movement of the clamping block 21 will compress the return spring 20. When the hand is released, the clamping block 21 will push the part of the sheet metal that exceeds the limit under the elastic recovery action of the return spring 20. Because the specifications of the return spring 20 are the same, its elasticity is also the same, and eventually the part of the sheet metal that exceeds the limit is squeezed and fixed in the middle position of the two clamping blocks 21, so that the sheet metal that exceeds the inconvenient position is not easy to change, avoiding the random movement of the sheet metal during cutting and ensuring the accuracy of cutting.
