Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing equipment, specifically to an auxiliary positioning component for a steel pipe cutting device. Background Technology

[0002] With the development of the manufacturing industry, the demand for steel pipes is increasing, and the corresponding processing technology also needs to be continuously improved. Cutting is an important part of the steel pipe production process, and the cutting quality directly affects the quality of the final product. In the existing steel pipe cutting process, it is usually necessary to accurately position the pipe to ensure cutting accuracy and efficiency.

[0003] For example, application number CN202122055349.3 discloses a stainless steel pipe cutting device, including a cutting mechanism. The cutting mechanism includes a base, a lifting frame slidably mounted on the base, a drive motor mounted on the lifting frame, a cutting wheel driven by the drive motor, and a drive assembly for lifting the lifting frame. A pressure block for pressing the pipe is reciprocally slidably mounted on one side of the cutting wheel on the lifting frame. The sliding direction of the pressure block is parallel to the movement direction of the lifting frame. A clamping spring is provided on the lifting frame to drive the pressure block downwards. The sliding stroke of the pressure block includes a minimum limiting position. When the pressure block is in the limiting position, its horizontal height is lower than the horizontal height of the cutting wheel. This utility model has the following advantages and effects: low production cost, low usage cost, and low maintenance cost, thereby greatly reducing the daily expenses of enterprises.

[0004] Based on the search of the aforementioned patents and the discovery of existing equipment, although the aforementioned equipment can solve the problem that existing positioning mechanisms require the use of two cylinders as a drive source, which greatly increases the production, use, and maintenance costs of the cutting device and significantly increases the daily expenses of enterprises, during use, the aforementioned equipment requires the user to manually support and straighten the steel pipe before the pressing and fixing device presses down on the steel pipe until the fixing device presses down on the steel pipe. However, the cutting device descends at the same time as the fixing device presses down, which is not only very dangerous, but also makes it impossible to keep the steel pipe in a straightened state continuously. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide an auxiliary positioning component for a steel pipe cutting device. This component has the advantage of auxiliary positioning and solves the problem that before the steel pipe is pressed down and fixed by the pressing device, the user needs to manually support and straighten the steel pipe until the fixing device presses down on the steel pipe. However, the cutting device descends along with the fixing device as it presses down, which is not only very dangerous but also makes it impossible to keep the steel pipe in a straightened state.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary positioning component for a steel pipe cutting device, comprising a base plate, a lifting frame, a cutting device, and a pressing device. The bottom of the lifting frame is fixedly connected to the left side of the top of the base plate, the left side of the cutting device is fixedly connected to the right side of the lifting frame, the front of the pressing device is fixedly connected to the back of the cutting device, first positioning blocks are fixedly connected to both sides of the left side of the top of the base plate, a sliding groove is provided on the right side of the top of the base plate, a second positioning block is provided inside the sliding groove, a screw is threadedly connected to the inner wall of the second positioning block, the right side of the screw extends through to the right side of the base plate, an acceleration mechanism is fixedly connected to the right side of the screw, and support components are provided on both sides of the inner wall of the sliding groove.

[0007] As a preferred embodiment of this utility model, the speed-increasing mechanism includes a small gear, the left side of which is fixedly connected to the right side of the screw, and a large gear is movably connected to the front side of the right side of the base plate via a pin. The large gear meshes with the small gear, and a convex handle is movably connected to the front side of the right side of the large gear via a pin.

[0008] In a preferred embodiment of this invention, the support assembly includes a mounting groove, which is formed on both sides of the inner wall of the slide groove. A bearing is movably connected to the inner wall of the mounting groove, and both sides of the screw surface are movably connected to the inner wall of the bearing.

[0009] As a preferred embodiment of the present invention, the second positioning block has grooves on both sides, and a roller is provided inside the groove. The two sides of the roller are movably connected to the two sides of the inner wall of the groove through axle pins, and the outer side of the roller is slidably connected to the two sides of the inner wall of the groove.

[0010] As a preferred embodiment of this utility model, aluminum foil tubes are sleeved on both sides of the screw surface, the inner side of the aluminum foil tubes is fixedly connected to both sides of the second positioning block, and the outer side of the aluminum foil tubes is fixedly connected to both sides of the inner wall of the slide groove.

[0011] As a preferred embodiment of this utility model, a protective cover is fixedly connected to the right side of the base plate, and both the large gear and the small gear are located inside the protective cover.

[0012] As a preferred embodiment of the present invention, a first rubber pad is fixedly connected to the left side of the first positioning block, and a second rubber pad is fixedly connected to the left side of the second positioning block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a first positioning block and a second positioning block, allows the user to rotate a screw after placing the steel pipe on the bottom plate. This causes the second positioning block to move along the slide track and gradually push the steel pipe towards the first positioning block. Subsequently, the first and second positioning blocks clamp and cooperate to straighten and hold the steel pipe. This solves the problem that in the above-mentioned equipment, before the steel pipe is pressed down and fixed by the pressing device, the user needs to manually support and straighten the steel pipe until the fixing device presses down on the steel pipe. However, when the fixing device presses down, the cutting device also descends, which is not only very dangerous, but also makes it impossible to keep the steel pipe in a straightened state. This invention achieves the effect of auxiliary positioning.

[0015] 2. By setting up an acceleration mechanism, when the second positioning block 7 is moved by rotating the screw and pushing the steel pipe, the user holds the convex handle and uses the convex handle to rotate the large gear, which drives the small gear to rotate. Through the gear ratio difference between the large gear and the small gear, a phenomenon is formed in which the small gear rotates several times for the large gear to rotate once. This makes the small gear quickly drive the screw to rotate, and finally the screw quickly drives the second positioning block to move along the slide groove trajectory, thereby improving the user's ease of operation.

[0016] 3. By setting up a support component, the bearing in the mounting groove rotates together with the screw as it rotates and drives the second positioning block to move. The bearing provides a rotation support point for the screw, dispersing the pressure when the screw rotates, so that the screw can rotate stably, thereby improving the service life of the screw.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, the positioning component of a stainless steel pipe cutting device 3 provided by this utility model includes a base plate 1, a lifting frame 2, a cutting device 3, and a pressing device 4. The bottom of the lifting frame 2 is fixedly connected to the left side of the top of the base plate 1, the left side of the cutting device 3 is fixedly connected to the right side of the lifting frame 2, and the front of the pressing device 4 is fixedly connected to the back of the cutting device 3. First positioning blocks 5 are fixedly connected to both sides of the top left side of the base plate 1. A sliding groove 6 is provided on the right side of the top of the base plate 1. A second positioning block 7 is provided inside the sliding groove 6. A screw 8 is threadedly connected to the inner wall of the second positioning block 7. The right side of the screw 8 extends through to the right side of the base plate 1. An acceleration mechanism 9 is fixedly connected to the right side of the screw 8. Support components 10 are provided on both sides of the inner wall of the sliding groove 6.

[0023] refer to Figure 1 and Figure 3 The speed-increasing mechanism 9 includes a small gear 91, the left side of which is fixedly connected to the right side of the screw 8. A large gear 92 is movably connected to the front right side of the base plate 1 via a pin. The large gear 92 meshes with the small gear 91. A convex handle 93 is movably connected to the front right side of the large gear 92 via a pin.

[0024] As a technical optimization of this utility model, by setting up an acceleration mechanism 9, when the second positioning block 7 is moved by rotating the screw 8 to push the steel pipe, the user holds the convex handle 93 and uses the convex handle 93 to rotate the large gear 92, which drives the small gear 91 to rotate. Through the gear ratio difference between the large gear 92 and the small gear 91, a phenomenon is formed in which the small gear 91 rotates several times for the large gear 92 to rotate once. This causes the small gear 91 to quickly drive the screw 8 to rotate, and finally the screw 8 quickly drives the second positioning block 7 to move along the track of the slide groove 6, thereby improving the user's ease of operation.

[0025] refer to Figure 3 The support component 10 includes a mounting groove 101, which is formed on both sides of the inner wall of the slide 6. The inner wall of the mounting groove 101 is movably connected to a bearing 102, and both sides of the surface of the screw 8 are movably connected to the inner wall of the bearing 102.

[0026] As a technical optimization of this utility model, by setting a support component 10, when the screw 8 rotates and drives the second positioning block 7 to move, the bearing 102 in the mounting groove 101 rotates together. The bearing 102 provides a rotation support point for the screw 8, dispersing the pressure when the screw 8 rotates, so that the screw 8 can rotate stably, thereby improving the service life of the screw 8.

[0027] refer to Figure 3 The second positioning block 7 has grooves 11 on both sides, and rollers 12 are installed inside the grooves 11. The two sides of the rollers 12 are movably connected to the two sides of the inner wall of the grooves 11 through pins. The outer side of the rollers 12 is slidably connected to the two sides of the inner wall of the slide groove 6.

[0028] As a technical optimization of this utility model, by setting the groove 11 and the roller 12, during the process of the screw 8 driving the second positioning block 7 to move along the track of the slide 6, the roller 12 in the groove 11 of the second positioning block 7 rotates against the inner wall of the slide 6, isolating the direct contact between the second positioning block 7 and the slide 6, and by rotating the roller 12, the frictional resistance is reduced, making the movement of the second positioning block 7 smoother, thereby improving the user's work efficiency.

[0029] refer to Figure 3 Aluminum foil tubes 13 are fitted on both sides of the surface of the screw 8. The inner side of the aluminum foil tube 13 is fixedly connected to both sides of the second positioning block 7, and the outer side of the aluminum foil tube 13 is fixedly connected to both sides of the inner wall of the slide groove 6.

[0030] As a technical optimization of this utility model, by setting an aluminum foil tube 13, during the process of the screw 8 driving the second positioning block 7 to move along the track of the slide groove 6, the aluminum foil tube 13 will expand and fold accordingly, always wrapping the screw 8. Then, when the cutting device 3 cuts the steel pipe, the metal flying off generated by the cutting will be blocked by the aluminum foil tube 13 when it splashes onto the screw 8, preventing the metal flying off from adhering to the screw 8 and causing blockage or jamming when the screw 8 rotates to drive the second positioning block 7 to move, thereby improving the stability of the screw 8 rotating to drive the second positioning block 7 to move.

[0031] refer to Figure 1 and Figure 3 A protective cover 14 is fixedly connected to the right side of the base plate 1, and the large gear 92 and the small gear 91 are both located inside the protective cover 14.

[0032] As a technical optimization of this utility model, by setting a protective cover 14, when the cutting device 3 cuts the steel pipe and metal flying is generated due to cutting, the protective cover 14 covers and shields the large gear 92 and the small gear 91, preventing the metal flying from sticking to the meshing of the large gear 92 and the small gear 91, causing blockage and jamming when the large gear 92 drives the small gear 91 to rotate, thereby improving the stability when the large gear 92 drives the small gear 91 to rotate.

[0033] refer to Figure 3 The left side of the first positioning block 5 is fixedly connected to the first rubber pad 15, and the left side of the second positioning block 7 is fixedly connected to the second rubber pad 16.

[0034] As a technical optimization of this utility model, by setting a first rubber pad 15 and a second rubber pad 16, when the second positioning block 7 pushes the steel pipe closer to the first positioning block 5, and then clamps and corrects the steel pipe to position it, the first rubber pad 15 and the second rubber pad 16 are squeezed and deformed, which isolates the first positioning block 5 and the second positioning block 7 from direct contact with the steel pipe, and prevents the steel pipe from being scratched and damaged during the pushing, clamping and correcting positioning, thus affecting the surface strength of the steel pipe.

[0035] The working principle and usage process of this utility model are as follows: When using the device, the user places the steel pipe on the base plate 1, holds the convex handle 93, and uses the convex handle 93 to rotate the large gear 92, driving the small gear 91 to rotate. Due to the gear ratio difference between the large gear 92 and the small gear 91, the large gear 92 rotates one revolution while the small gear 91 rotates several revolutions. This causes the small gear 91 to quickly drive the screw 8 to rotate, causing the second positioning block 7 to move rapidly along the track of the slide groove 6, and gradually pushing the steel pipe towards the first positioning block 5. Then, during the rotation of the screw 8, the bearing 102 in the mounting groove 101... The screws rotate together, and the bearing 102 provides a rotation support point for the screw 8, dispersing the pressure when the screw 8 rotates and stabilizing the rotation of the screw 8. Finally, the steel pipe is clamped, positioned and corrected by the cooperation of the first positioning block 5 and the second positioning block 7, and held in place. At this time, the user can first start the cutting device 3, and then start the lifting frame 2 to drive the cutting device 3 to move down. At the same time, the pressing device 4 moves down together and contacts the corrected and positioned steel pipe first, pressing it down and fixing it. Then the cutting device 3 cuts the steel pipe, thus having the advantage of auxiliary positioning.

[0036] In summary, this steel pipe cutting device uses an auxiliary positioning component. By setting a first positioning block 5 and a second positioning block 7, after the steel pipe is placed on the bottom plate 1, the user rotates the screw 8, which drives the second positioning block 7 to move along the track of the slide groove 6, and gradually pushes the steel pipe towards the first positioning block 5. Then, the first positioning block 5 and the second positioning block 7 clamp and cooperate to straighten and hold the steel pipe. This solves the problem of the above-mentioned equipment, which requires the user to manually support and straighten the steel pipe before the pressing and fixing device presses down on the steel pipe, but the cutting device also descends at the same time as the fixing device, which is not only very dangerous, but also makes it impossible to keep the steel pipe in a straightened state.
