Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a rapid auxiliary circle cutting device. Background Technology

[0002] In fields such as machinery manufacturing and construction, steel plates are frequently required to be circularly cut to meet the assembly needs of various equipment parts and structural components. The cutting accuracy and processing efficiency of circular steel plates directly affect the quality and progress of subsequent production stages. Therefore, an efficient and stable circular cutting auxiliary device is of great significance for improving overall production efficiency.

[0003] However, current technologies for cutting circular steel plates have many shortcomings. Traditional cutting methods rely heavily on manual marking and handheld cutting tools, which not only result in large cutting errors, leading to substandard circular steel plates that fail to meet usage requirements, but also necessitate secondary processing with other equipment, increasing processing costs and time. Furthermore, manual operation is physically demanding for workers, and inconsistent operation can cause fluctuations in cutting quality, further extending the processing cycle and severely impacting production efficiency.

[0004] Therefore, those skilled in the art have provided a rapid auxiliary circle cutting device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a rapid auxiliary circular cutting device. This device effectively solves the problems of substandard circular steel plate cutting, the need for other equipment to assist in processing, long processing time, and high labor intensity for operators. It saves time and effort, and significantly improves the stability and accuracy of operation, and has broad application significance.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rapid auxiliary circle cutting device includes a magnetic base, a first support frame, a second support frame, a ruler frame, and an oxy-fuel cutting gun. The first support frame is fixedly connected to the magnetic base, and a height adjustment component is provided inside the first support frame. A lateral adjustment component is provided inside the second support frame and the ruler frame.

[0008] The height adjustment assembly includes a height adjustment screw, and the lateral adjustment assembly includes a first lateral adjustment screw and a second lateral adjustment screw. The outer walls of the height adjustment screw, the first lateral adjustment screw, and the second lateral adjustment screw are respectively threaded with a height adjustment slider, a first lateral adjustment slider, and a second lateral adjustment slider. One end of the height adjustment slider, the first lateral adjustment slider, and the second lateral adjustment slider is respectively fixedly connected to a first mounting base, a first connecting frame, and a second connecting frame. The lower end of the second connecting frame is fixedly connected to a second mounting base, and the lower end of the first connecting frame is rotatably connected to a rotating base. The second support frame, the scale frame, and the gas cutting gun are respectively provided with disassembly and assembly components between them and the first mounting base, the rotating base, and the second mounting base.

[0009] The above technical solution allows the height adjustment screw to rotate, and through the threaded engagement between the screw and the height adjustment slider, the first mounting base is raised and lowered synchronously. This allows for flexible adjustment of the height of components such as the gas cutting gun, adapting to different thicknesses of plates or cutting height requirements, and ensuring the vertical stability of the cut circle. The rotation of the first and second lateral adjustment screws, relying on the threaded action between the screws and the first and second lateral adjustment sliders, respectively drives the first and second connecting frames to move laterally along the second support frame and the ruler frame. This allows for flexible adjustment of the horizontal position of the gas cutting gun and the ruler frame, meeting the radius requirements for cutting circles of different diameters, replacing manual marking, significantly reducing cutting size deviations, and improving the accuracy and efficiency of the cut circle.

[0010] Furthermore, the assembly / disassembly assembly includes multiple T-blocks, each of which is fixedly connected to the corresponding second support frame, ruler frame, and gas cutting gun. The front ends of the first mounting base, rotating base, and second mounting base are all provided with T-slots. The multiple T-blocks are slidably disposed within the corresponding T-slots. The inner walls of the multiple T-slots are provided with spring-loaded grooves. Movable rods are movably disposed inside the multiple spring-loaded grooves. A fixing block is fixedly connected to one end of each of the multiple movable rods near the corresponding T-block. A fixing slot is provided on the outer wall of each of the multiple T-blocks. A return spring is movably sleeved on the outer wall of each of the multiple movable rods.

[0011] Through the above technical solution, the T-block slides into the T-slot to achieve initial positioning, and the return spring pushes the fixing block into the fixing slot to complete the quick locking of the components (second support frame, ruler frame, gas cutting gun) and the mounting base. The moving rod moves to drive the fixing block to compress the return spring and exit the slot, which can then be disassembled and replaced. This facilitates the replacement of different specifications of accessories (such as ruler frames of different lengths) according to cutting needs, or the repair and replacement of damaged parts, improving the versatility and maintenance convenience of the device and reducing the difficulty of operation for workers.

[0012] Furthermore, a support plate is fixedly connected to the upper end of the first mounting base. Two fixing plates are fixedly connected to one side of the support plate and the upper part of the outer wall of the rotating base. A rotating shaft is rotatably connected between the front and rear inner walls of the two fixing plates. A tension wheel is fixedly sleeved on the outer wall of the two rotating shafts. A tension line is provided between the outer wall of the two tension wheels and the corresponding second support frame and scale frame. A positioning frame is fixedly connected to the front end of the two fixing plates located at the front. A reset groove is opened on one side of the two positioning frames. A reset block is slidably arranged inside the two reset grooves. A positioning block is fixedly connected to one end of the two reset blocks. Multiple positioning slots are opened on the front part of the outer wall of the two rotating shafts. The two positioning blocks are engaged with the corresponding positioning slots. A reset spring is fixedly connected between the inner walls of the opposite ends of the two reset blocks and the corresponding reset grooves.

[0013] Through the above technical solution, the tension line hook is on the second support frame and the ruler frame. When the rotating shaft rotates, the tension wheel rotates synchronously to tighten and loosen the tension line, so that the tension line is in a taut state. This fixes the relative position of the second support frame, the ruler frame and the mounting base, preventing them from swaying up and down, and further ensuring the cutting effect. The movement of the reset block drives the positioning block to compress the reset spring and exit the positioning slot, which can unlock the rotating shaft to adjust the tension line. After adjustment, the positioning block is locked into the slot by the spring force, maintaining the tension of the tension line.

[0014] Furthermore, the first support frame has a transmission groove inside, a worm gear is rotatably connected between the front and rear inner walls of the transmission groove, a transmission shaft is rotatably connected between the upper and lower inner walls of the transmission groove, a worm wheel is fixedly sleeved on the outer wall of the transmission shaft, the worm gear and the worm wheel mesh, the front end of the worm gear passes through the first support frame and is rotatably connected to a first knob, the upper end of the transmission shaft passes through the first support frame and is fixedly connected to a height adjustment screw, and one side of the first lateral adjustment screw and the second lateral adjustment screw both pass through the corresponding second support frame and the scale frame and are fixedly connected to a second knob;

[0015] Through the above technical solution, the first knob drives the worm to rotate, the worm meshes with the worm wheel to drive the transmission shaft to rotate, and then causes the height adjustment screw to rotate, realizing power transmission and motion conversion. The second knob can rotate the first lateral adjustment screw and the second lateral adjustment screw.

[0016] Furthermore, the multiple fixing blocks are engaged in the corresponding fixing slots, and the two ends of the multiple return springs are respectively fixedly connected to the inner wall of the opposite end of the corresponding fixing block and the return groove.

[0017] Through the above technical solution, the return spring provides continuous elastic force to the fixed block, so that it is stably inserted into the fixed slot, locking the connection between the T-block and the T-slot. Pulling the movable rod causes the fixed block to compress the return spring and exit the slot to complete the unlocking.

[0018] Furthermore, each of the two reset slots has a toggle groove on its lower inner wall, and a toggle block is movably disposed inside each of the two toggle grooves. Each of the two toggle blocks is fixedly connected to the corresponding reset block.

[0019] With the above technical solution, the actuating block and the reset block are connected. When the worker moves the actuating block along the actuating groove, it can drive the positioning block to compress the reset spring and exit the positioning groove, thus unlocking the rotating shaft. The tension line can be easily adjusted without the need for tools.

[0020] Furthermore, the height adjustment screw is rotatably connected between the upper and lower inner walls of the first support frame, the first lateral adjustment screw and the second lateral adjustment screw are respectively rotatably connected between the inner walls of the second support frame and the ruler frame on both sides, and the height adjustment slider, the first lateral adjustment slider and the second lateral adjustment slider are all slidably disposed inside the corresponding first support frame, second support frame and ruler frame.

[0021] Through the above technical solution, the height adjustment screw and the lateral adjustment screw are respectively threaded with the corresponding slider. The slider is restricted by the inner wall of the frame (first support frame, second support frame, scale frame), which converts the rotation of the screw into the linear motion of the slider.

[0022] Furthermore, the ends of the plurality of movable rods away from the corresponding T-blocks all pass through the corresponding first mounting base, rotating base and second mounting base and are fixedly connected to a pull block;

[0023] With the above technical solution, the pull block is fixed to the movable rod. When the worker pulls the pull block, the movable rod and the fixed block can move, so that the fixed block compresses the return spring and exits the slot.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model proposes a rapid auxiliary circular cutting device. The height adjustment component, through worm gear transmission and lead screw slider cooperation, can adjust the height of components such as the gas cutting gun to adapt to plates of different thicknesses, reducing cutting deviations caused by unsuitable height. The lateral adjustment component, with the help of the lateral lead screw slider structure, can flexibly adjust the lateral position of the ruler frame and the gas cutting gun to determine the circular cutting radius, greatly reducing cutting errors and ensuring that the cut circular steel plates meet the requirements. No secondary processing is required, saving the trouble of additional equipment processing. At the same time, the cooperation between the tension wheel and the tension line enhances the stability of the second support frame and the ruler frame during cutting, further reducing cutting deviations and ensuring cutting quality.

The height adjustment slider 9, the first lateral adjustment slider 12, and the second lateral adjustment slider 15 are all slidably disposed inside the corresponding first support frame 2, second support frame 3, and scale frame 4. The height adjustment screw 8 and the lateral adjustment screw are threadedly engaged with the corresponding sliders. The sliders are restricted by the inner wall of the frame (first support frame 2, second support frame 3, scale frame 4), converting the rotation of the screw into linear motion of the slider. One end of the height adjustment slider 9, the first lateral adjustment slider 12, and the second lateral adjustment slider 15 is fixedly connected to the first mounting base 10, the first connecting frame 13, and the second connecting frame 16, respectively. The lower end of the second connecting frame 16 is fixedly connected to the second mounting base 46, and the lower end of the first connecting frame 13 is rotatably connected to the rotating base 17.

Tensioning lines 36 are provided between the outer walls of the two tensioning wheels 35 and the corresponding second support frame 3 and scale frame 4. Positioning frames 37 are fixedly connected to the front ends of the two fixing plates 33 located at the front. Reset grooves 38 are opened on one side of the two positioning frames 37. Reset blocks 39 are slidably arranged inside the two reset grooves 38. Positioning blocks 40 are fixedly connected to one end of the two reset blocks 39. Multiple positioning slots 41 are opened on the front part of the outer walls of the two rotating shafts 34. The two positioning blocks 40 are engaged with the corresponding positioning slots 41. Reset springs 42 are fixedly connected between the inner walls of the two reset blocks 39 and the opposite ends of the corresponding reset grooves 38. The tensioning lines 36 are hooked on... On the second support frame 3 and the ruler frame 4, when the rotating shaft 34 rotates, the tension wheel 35 rotates synchronously to tighten and loosen the tension line 36, keeping the tension line 36 in a taut state. This fixes the relative positions of the second support frame 3, the ruler frame 4, and the mounting base, preventing them from wobbling up and down and further ensuring the cutting effect. The movement of the reset block 39 causes the positioning block 40 to compress the reset spring 42 and exit the positioning slot 41, which unlocks the rotating shaft 34 to adjust the tension line 36. After adjustment, the positioning block 40 is locked into the slot by the spring force. To maintain the tension of the tension line 36, the lower inner walls of the two reset slots 38 are provided with actuating slots 43, and actuating blocks 44 are movably arranged inside the two actuating slots 43.

The tension line 36 can be easily adjusted without the need for tools.

[0040] Reference Figure 2 and Figure 4The assembly / disassembly component 7 includes multiple T-blocks 24, each fixedly connected to the corresponding second support frame 3, scale frame 4, and gas cutting torch 45. The front ends of the first mounting base 10, rotating base 17, and second mounting base 46 are all provided with T-slots 25. The multiple T-blocks 24 slide within their respective T-slots 25. The inner walls of each T-slot 25 are provided with spring-loaded grooves 26, and movable rods 27 are movably mounted inside each spring-loaded groove 26. These movable rods 27 are positioned close to their respective T-blocks 24. One end of each T-block 24 is fixedly connected to a fixing block 28. The outer walls of each T-block 24 are provided with fixing slots 29. The outer walls of each movable rod 27 are movably fitted with return springs 30. Each fixing block 28 is engaged within its corresponding fixing slot 29. The two ends of each return spring 30 are fixedly connected to the inner walls of the corresponding fixing block 28 and the return groove 26 at opposite ends. The return springs 30 provide continuous elastic force to the fixing blocks 28, ensuring they are stably engaged in the fixing slots 29 and locking the T-blocks 24. Connecting to the T-slot 25, pulling the movable rod 27 causes the fixed block 28 to compress the return spring 30 and disengage from the slot, completing the unlocking. The T-block 24 slides into the T-slot 25 for initial positioning. The return spring 30 pushes the fixed block 28 into the fixed slot 29, completing the quick locking of the components (second support frame 3, scale frame 4, gas cutting gun 45) to the mounting base. Moving the movable rod 27 causes the fixed block 28 to compress the return spring 30 and disengage from the slot, allowing for easy replacement of different specifications according to cutting needs. The device can be improved by replacing damaged parts (such as rulers of different lengths 4) and enhancing its versatility and ease of maintenance, thus reducing the difficulty of operation for workers. The ends of multiple movable rods 27 that are away from the corresponding T-blocks 24 all pass through the corresponding first mounting base 10, rotating base 17 and second mounting base 46 and are fixedly connected to a pull block 31. The pull block 31 is fixed to the movable rod 27. When the worker pulls the pull block 31, the movable rod 27 and the fixed block 28 can be moved, thereby realizing the action of the fixed block 28 compressing the return spring 30 and disengaging it from the slot.

[0041] Working principle: When this quick-assist circular cutting device is working, the magnetic base 1 is first fixed in a suitable position on the plate to be cut, providing stable support for the entire device. When adjusting the height, the first knob 22 is turned, and the worm gear 19 rotates accordingly, driving the worm wheel 21 and the transmission shaft 20 to rotate, which in turn drives the height adjustment screw 8 to rotate. Under the action of the threaded engagement and the limiting structure inside the first support frame 2, the height adjustment slider 9 moves up and down with the first mounting base 10, thereby adjusting the height of the second support frame 3, the ruler frame 4 and the gas cutting gun 45 to adapt to plates of different thicknesses or cutting scenarios. When adjusting the horizontal position, the corresponding second knob 23 is turned, and the first horizontal adjustment screw 11 and the second horizontal adjustment screw 14 rotate respectively. Under the constraint of the threaded transmission and the limiting structure of their respective frames, the first horizontal adjustment slider 12 and the second horizontal adjustment slider 15 drive the first connecting frame 13 and the second connecting frame 16 to move respectively, thereby adjusting the horizontal position of the ruler frame 4 and the gas cutting gun 45 to determine the radius of the required circular cutting. If a component needs to be replaced, the following steps are performed via assembly / disassembly: Pulling the pull block 31 disengages the fixing block 28 from the fixing slot 29, allowing the second support frame 3, ruler frame 4, or gas cutting gun 45 to be removed. After replacement, slide the T-block 24 into the corresponding T-slot 25, and the return spring 30 pushes the fixing block 28 to automatically engage with the fixing slot 29 to complete the fixation. Furthermore, the rotating shaft 34 drives the tensioning wheel 35 to raise and lower the tension line 36, keeping it taut to fix the second support frame 3 and ruler frame 4 and prevent them from wobbling. The length of the tension line 36 can be adjusted by moving the toggle block 44 to disengage the positioning block 40 from the positioning slot 41, unlocking the rotating shaft 34. After adjustment, the positioning block 40 engages with the slot under the action of the return spring 42, ensuring the stability of each component during cutting and ultimately achieving rapid assisted cutting of a circle.
