Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water conservancy pipeline processing technology, specifically referring to an end grinding device for water conservancy pipeline processing. Background Technology
[0002] During the construction and laying of water conservancy pipelines, in order to ensure the sealing of the connections between pipelines, the ends of the pipelines need to be ground and leveled before hot melting or welding. Existing grinding devices, such as the end grinding device for water conservancy pipeline processing disclosed in application number CN202321134297.1, use a drive motor to drive the grinding roller to rotate at high speed to perform on-site grinding of the pipeline ends.
[0003] However, in actual construction, the existing manual hand-grinding method relies on human experience to ensure the flatness of the end face, making it difficult to guarantee the grinding effect. Other end face grinding machines grind the end face by clamping and feeding the pipe, but the single feed amount of the pipe is constant. If it is too large, it will easily cause the pipe to collide with the grinding disc and be damaged. If it is too small, the operation will be time-consuming and laborious. Therefore, we propose an end face grinding device for water conservancy pipeline processing to solve the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this utility model provides an end grinding device for water conservancy pipeline processing, which effectively solves the problem that the current end grinding of water conservancy pipeline processing is done manually, making it difficult to guarantee uniform results. It also solves the problem that the existing grinding device has a slow feeding speed and is prone to causing pipeline collision and damage.
[0005] The technical solution adopted by this utility model is as follows: This utility model proposes an end grinding device for processing water conservancy pipelines, including a base plate, a support plate vertically fixed on one side of the upper end of the base plate, a grinding machine fixed on the support plate, and the grinding machine can adapt to grinding pipelines of different sizes by changing the grinding disc; a support slide rail is symmetrically fixed on the upper end of the base plate, and the support plate and the grinding machine are located on the side end of the support slide rail; a support slide table is slidably connected on the support slide rail; a doubling mechanism is fixed on the base plate, and the doubling mechanism is connected to the bottom of the support slide table.
[0006] As an improvement to this solution, the upper end of the support slide is provided with two sets of clamping and feeding mechanisms.
[0007] As an improvement to this solution, the doubling mechanism includes a fixed rack, which is fixed to the middle of the upper end of the base plate and is arranged parallel to the support slide rail. A drive gear and a driven gear are meshed on the fixed rack. A support guide plate is arranged parallel to one side of the fixed rack and is fixed to the base plate. A movable rack one is slidably connected to the upper end of the support guide plate near the fixed rack, and the movable rack one meshes with the upper side of the drive gear and the driven gear. A movable rack two is slidably connected to the movable rack one and meshes with the driven gear.
[0008] As an improvement to this solution, a bearing seat is fixedly connected to the base plate, and a rotating shaft is rotatably connected to the bearing seat. One end of the rotating shaft passes through the side wall of the support slide rail, and a rocker handle is fixed to the end of the rotating shaft that passes through the support slide rail.
[0009] As an improvement to this solution, two sets of sliders are slidably connected on the support guide plate. The two sets of sliders are rotatably connected to the drive gear and the driven gear, respectively. A push rod is rotatably connected to one side of the slider that is symmetrical to the drive gear. A rocker arm is rotatably connected to the push rod, and the other end of the rocker arm is fixed to the rotating shaft.
[0010] As an improvement to this solution, the clamping and feeding mechanism includes a feed screw, a feed slide, a bidirectional screw, and a centering clamp. The feed screw is rotatably connected to the support slide and is arranged in the same plane as the fixed rack. The feed slide is slidably connected to the support slide and threadedly connected to the feed screw. The bidirectional screw is rotatably connected to the feed slide and is arranged perpendicular to the feed screw. The centering clamp is slidably connected to the feed slide and threadedly connected to the bidirectional screw.
[0011] As an improvement to this solution, a dust cover is fixed on the support plate and is located on the outside of the grinding machine, and a material receiving frame is provided below the grinding machine.
[0012] As an improvement to this solution, the first movable rack is located between the support guide plate and the second movable rack, and the upper end of the first movable rack is fixedly connected to the bottom of the support slide by bolts.
[0013] The beneficial effects of this utility model by adopting the above structure are as follows:
[0014] 1. The clamping feeding mechanism enables the pipe to be clamped and fixed, and it can slowly come into contact with the grinding disc, avoiding the problem of damage to the pipe end face caused by direct collision.
[0015] 2.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the present invention proposes an end-grinding device for processing water conservancy pipelines, comprising a base plate 1, a support plate 2 vertically fixed on one side of the upper end of the base plate 1, a grinder 3 fixed on the support plate 2, and the grinder 3 being adaptable to grinding pipelines of different sizes by changing the grinding disc; a support slide rail 4 symmetrically fixed on the upper end of the base plate 1, and the support plate 2 and the grinder 3 being located on the side end of the support slide rail 4; a support slide table 5 slidably connected on the support slide rail 4; a doubling mechanism 6 fixed on the base plate 1, and the doubling mechanism 6 being connected to the bottom of the support slide table 5; the doubling mechanism 6 pushing the support slide table 5 to slide along the support slide rail 4 toward the grinder 3; and two sets of clamping and feeding mechanisms 7 provided on the upper end of the support slide table 5, which center and clamp the water conservancy pipeline.
[0026] like Figure 2 river Figure 3 As shown, the doubling mechanism 6 includes a fixed rack 8, which is fixed to the middle of the upper end of the base plate 1 and is arranged parallel to the support slide rail 4. A drive gear 9 and a driven gear 10 are meshed on the fixed rack 8. A support guide plate 11 is arranged parallel to one side of the fixed rack 8 and is fixed to the base plate 1. A movable rack 12 is slidably connected to the upper end of the support guide plate 11 near the fixed rack 8. The movable rack 12 is meshed on the upper side of the drive gear 9 and the driven gear 10. A movable rack 2 13 is slidably connected to the movable rack 12 and is meshed with the driven gear 10. The movable rack 12 is located between the support guide plate 11 and the movable rack 2 13. The upper end of the movable rack 12 is fixedly connected to the bottom of the support slide 5 by bolts.
[0027] like Figure 1 and Figure 5 As shown, a bearing seat 14 is fixedly connected to the base plate 1, and a rotating shaft 15 is rotatably connected to the bearing seat 14. One end of the rotating shaft 15 passes through the side wall of the support slide rail 4, and a crank 16 is fixed to the end of the rotating shaft 15 that passes through the support slide rail 4. By rotating the crank 16, the rotating shaft 15 is driven to rotate, thereby driving the doubling mechanism 6.
[0028] like Figure 4 As shown, two sets of sliders 17 are slidably connected to the support guide plate 11. The two sets of sliders 17 are rotatably connected to the drive gear 9 and the driven gear 10, respectively. A push rod 18 is rotatably connected to one side of the slider 17 that is symmetrical to the drive gear 9. A rocker arm 19 is rotatably connected to the push rod 18, and the other end of the rocker arm 19 is fixed to the rotating shaft 15. The two sets of sliders 17 can ensure the stable operation of the drive gear 9 and the driven gear 10.
[0029] like Figure 1 and Figure 3As shown, the clamping and feeding mechanism 7 includes a feed screw 20, a feed slide 21, a bidirectional screw 22, and a centering clamp 23. The feed screw 20 is rotatably connected to the support slide 5 and is arranged in the same plane as the fixed rack 8. The feed slide 21 is slidably connected to the support slide 5 and threadedly connected to the feed screw 20. The bidirectional screw 22 is rotatably connected to the feed slide 21 and is arranged perpendicular to the feed screw 20. The centering clamp 23 is slidably connected to the feed slide 21 and threadedly connected to the bidirectional screw 22.
[0030] like Figure 1 As shown, a dust cover 24 is fixed on the support plate 2 and is located on the outside of the grinder 3. A receiving frame 25 is provided below the grinder 3. The dust cover 24 can collect the debris generated during grinding.
[0031] In practical use, the centering clamp 23 is separated by rotating the bidirectional screw 22, and the pipe is placed between the symmetrical centering clamps 23. Then, the bidirectional screw 22 is reversed, and the pipe is clamped and fixed by the V-shaped groove on the centering clamp 23. The grinder 3 is turned on, and the rocker handle 16 is turned to drive the rotating shaft 15 to rotate, so that the rocker arm 19 on the rocker handle 16 rotates accordingly. Rotating the push rod 18 connected to the rocker arm 19 pushes the slider 17 with the drive gear 9 to slide along the support guide plate 11. Under the action of the fixed rack 8, the drive gear 9 rotates while sliding with the slider 17, so that the moving rack 12 above it slides along the support guide plate 11 towards the grinder 3. At the same time, it drives the driven gear 10 meshing with it to move along the rack. The moving rack 12 rotates between the driven gear 10 and the moving rack 12. As the driven gear 10 rotates, the moving rack 23, which is slidably connected to the moving rack 12, pushes the support slide 5 along the support slide rail 4 towards the side of the grinder 3 under the drive of the driven gear 10, so that the pipe can quickly approach the grinder 3. When the block contacts, the crank handle 16 is released, and the feed screw 20 is rotated so that the feed slide 21, which is threaded on it, slowly approaches the side of the grinder 3 along the support slide 5, so that the end of the pipe gradually contacts the grinder 3 to complete the grinding. After the grinding is completed, the crank handle 16 is rotated in the opposite direction so that the pipe can be quickly removed. The above is the entire process of using the end grinding device for water conservancy pipeline processing.
[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
