Description

Technical Field

[0001] This utility model relates to the field of pipe fitting production and transportation equipment technology, and in particular to a pipe fitting feeding mechanism. Background Technology

[0002] When cutting pipe fittings, the fitting needs to be pushed in with the cutting position aligned, and then the fitting is cut.

[0003] During cutting, the pipe fitting is subjected to cutting force, which can easily cause vibration and displacement. To ensure the stability of the pipe fitting during cutting, a clamping mechanism is installed to hold and fix its position. Existing pipe fitting clamping mechanisms are fixed by threads. Under the action of cutting force, and because the pipe fitting is long, the effect of the cutting force is amplified, and the clamping mechanism is prone to loosening, affecting the cutting stability of the pipe fitting.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a pipe feeding mechanism to improve the clamping stability of pipes.

[0006] The technical solution of this utility model is as follows:

[0007] A pipe fitting feeding mechanism includes a support base, a limiting base, and a self-locking assembly. The support base includes a lower roller. The limiting base is disposed above the support base and includes an upper fixed plate, an electric telescopic rod, and an upper roller. The upper fixed plate is supported by a guide rod. The electric telescopic rod is disposed on the upper fixed plate. The pipe fitting is disposed between the upper roller and the lower roller. The self-locking assembly includes an upper self-locking link, a lower self-locking link, and a driving link. The upper self-locking link, the lower self-locking link, and the driving link are simultaneously hinged at a re-hinge point. The end of the upper self-locking link away from the re-hinge point is hinged to the upper fixed plate. The end of the lower self-locking link away from the re-hinge point is hinged to the upper roller. The end of the driving link away from the re-hinge point is hinged to the electric telescopic rod. The electric telescopic rod extends and retracts, pushing the upper and lower self-locking links vertically or folded in half.

[0008] A further technical solution is that a limiting block is provided on the guide rod; when the upper self-locking link and the lower self-locking link are vertical, the limiting block is flush with the hinge point, and the limiting block restricts the hinge point from moving further away from the end of the electric telescopic rod.

[0009] A further technical solution is that two self-locking components are symmetrically arranged along the axis of the electric telescopic rod.

[0010] A further technical solution is that the limiting seat further includes a lower fixing plate and a first sleeve; the first sleeve is fixed on the lower fixing plate; the first sleeve is sleeved on the guide rod; and the upper roller is disposed on the lower fixing plate.

[0011] A further technical solution is that a connecting block is provided at the end of the electric telescopic rod; the drive linkage is connected to the electric telescopic rod through the connecting block.

[0012] A further technical solution is that the diameters of the upper roller and the lower roller gradually decrease from both ends to the middle, forming a concave arc outer surface that fits the pipe fitting.

[0013] A further technical solution is that the support base further includes a second sleeve and a sliding seat; the second sleeve is sleeved on the sliding seat; the bottom of the second sleeve is sealed, and an elastic element is provided between the bottom of the sliding seat and the second sleeve.

[0014] A further technical solution is that a limiting groove is vertically formed on the wall of the second sleeve; a first extension is provided on the sliding seat; the first extension passes through the limiting groove.

[0015] A further technical solution is that a second extension is provided on the second sleeve; the second extension is located above the limiting groove; and limiting bolts are respectively aligned on the first extension and the second extension.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] (1) The pipe feeding mechanism of this utility model places the pipe between the upper roller and the lower roller. While the upper roller and the lower roller clamp and fix the pipe, they push the pipe along its length, causing the pipe to rotate and allowing it to move and be fed while being clamped. Additionally, a self-locking assembly is provided. When the electric telescopic rod extends or retracts, it drives the drive linkage to push the upper and lower self-locking linkages to a vertical position. At this time, the height of the upper roller decreases to clamp the pipe. Furthermore, the force exerted by the pipe on the upper roller is transmitted along the lower and upper self-locking linkages and is not transmitted to the drive linkage or the electric telescopic rod. This prevents the energy generated by vibration during pipe processing from being transmitted to the electric telescopic rod, thus avoiding damage and affecting its service life.

[0018] (2) Further, a limit block is set. The limit block and the drive linkage work together to limit the position of the upper self-locking linkage and the lower self-locking linkage, thereby enhancing the structural stability of the self-locking assembly.

[0019] (3) Furthermore, two self-locking components are symmetrically arranged along the axis of the electric telescopic rod. The two self-locking components can better support the upper roller and improve the stability of the limit seat. Attached Figure Description

It should be noted that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the content disclosed herein.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Figure 1 The front view of the pipe feeding mechanism of this utility model in the self-locking state is shown. Figure 2 This diagram shows a partial view of the limiting seat and self-locking component in the pipe feeding mechanism of this invention in the unlocked state. Please refer to... Figure 1 and Figure 2 The pipe fitting feeding mechanism includes a support base 1, a limiting seat 4, and a self-locking assembly 2. The support base 1 includes a lower roller 11. The limiting seat 4 is positioned above the support base 1. The limiting seat 4 includes an upper fixed plate 41, an electric telescopic rod 42, and an upper roller 45. The upper fixed plate 41 is supported by a guide rod 3. The electric telescopic rod 42 is mounted on the upper fixed plate 41. The pipe fitting 5 is positioned between the upper roller 45 and the lower roller 11. While the upper roller 45 and the lower roller 11 clamp and fix the pipe fitting 5, they also push the pipe fitting 5 along its length. The pipe fitting 5 drives the upper roller 45 and the lower roller 11 to rotate, allowing the pipe fitting 5 to move and feed while being clamped.

[0028] Furthermore, the self-locking assembly 2 includes an upper self-locking link 21, a lower self-locking link 22, and a drive link 23. The upper self-locking link 21, lower self-locking link 22, and drive link 23 are all hinged at a re-hinge point 24. The end of the upper self-locking link 21 away from the re-hinge point 24 is hinged to an upper fixed plate 41. The end of the lower self-locking link 22 away from the re-hinge point 24 is hinged to an upper roller 45. The end of the drive link 23 away from the re-hinge point 24 is hinged to an electric telescopic rod 42. The electric telescopic rod 42 extends and retracts, pushing the upper self-locking link 21 and lower self-locking link 22 vertically or folded in half. When the electric telescopic rod 42 extends and retracts, causing the drive link 23 to push the upper self-locking link 21 and lower self-locking link 22 to a vertical position, the height of the upper roller 45 decreases, clamping the pipe 5. Furthermore, the force exerted by fitting 5 on the upper roller 45 is transmitted along the lower self-locking link 22 and the upper self-locking link 21, and will not be transmitted to the drive link 23 and the electric telescopic rod 42. This prevents the energy generated by vibration during the processing of fitting 5 from being transmitted to the electric telescopic rod 42, which could damage the electric telescopic rod 42 and affect its service life.

[0029] Please refer to Figure 1 and Figure 2 A limiting block 31 is provided on the guide rod 3. When the upper self-locking link 21 and the lower self-locking link 22 are vertical, the limiting block 31 is aligned with the re-hinge point 24, and the limiting block 31 restricts the re-hinge point 24 from moving further away from the electric telescopic rod 42. The limiting block 31 and the drive link 23 work together to limit the position of the upper self-locking link 21 and the lower self-locking link 22, enhancing the structural stability of the self-locking assembly 2.

[0030] Preferably, two self-locking components 2 are symmetrically arranged along the axis of the electric telescopic rod 42. The two self-locking components 2 can better support the upper roller 45 and improve the stability of the limit seat 4.

[0031] More preferably, the limiting seat 4 further includes a lower fixed plate 44 and a first sleeve 441. The first sleeve 441 is fixed on the lower fixed plate 44. The first sleeve 441 is sleeved on the guide rod 3. The upper roller 45 is disposed on the lower fixed plate 44. The guide rod 3 restricts the movement path of the lower fixed plate 44 and the upper roller 45, ensuring that the upper roller 45 can accurately and reliably complete the predetermined action.

[0032] Please refer to Figure 1 and Figure 2 A connecting block 43 is provided at the end of the electric telescopic rod 42. The drive linkage 23 is connected to the electric telescopic rod 42 through the connecting block 43. The diameters of the upper roller 45 and the lower roller 11 gradually decrease from both ends to the middle, forming a concave arc outer surface that fits the pipe fitting 5. The concave arc outer surface can better fit the circular pipe fitting 5, improving the stability of the pipe fitting 5 held by the upper roller 45 and the lower roller 11.

[0033] Figure 3 This diagram shows a cross-sectional view of the support base in the pipe feeding mechanism of this invention at point A. Please refer to... Figure 3 The support base 1 also includes a second sleeve 12 and a sliding seat 14. The second sleeve 12 is fitted onto the sliding seat 14. The bottom of the second sleeve 12 is sealed, and an elastic element 13 is provided between the bottom of the sliding seat 14 and the second sleeve 12. The elastic support has a foot-feeling load-bearing capacity and overload capacity, and can effectively withstand the large loads and instantaneous impacts generated during the clamping of the pipe fitting 5.

[0034] Preferably, a limiting groove 121 is vertically formed on the wall of the second sleeve 12. A first extension 141 is provided on the sliding seat 14. The first extension 141 passes through the limiting groove 121. The limiting groove 121 and the first extension 141 cooperate to limit the movement path of the sliding seat 14, thereby improving the stability of the support seat 1.

[0035] More preferably, a second extension 122 is provided on the second sleeve 12. The second extension 122 is positioned above the limiting groove 121. Limiting bolts 142 are respectively aligned and provided on the first extension 141 and the second extension 122. By adjusting the position of the limiting bolts 142 and replacing them with limiting bolts 142 of different lengths, the stroke of the sliding seat 14 within the second sleeve 12 can be easily adjusted, improving the flexibility of the support seat 1.

[0036] The specific workflow of this utility model is as follows:

[0037] When clamping pipe fitting 5, pipe fitting 5 is placed on the lower roller 11, and then the electric telescopic rod 42 is extended. The extended electric telescopic rod 42 pushes the drive linkage 23, and the drive linkage 23 pushes the upper self-locking linkage 21 and the lower self-locking linkage 22 to swing until the limit block 31 contacts the re-hinge point 24. During this process, the lower fixing plate 44 moves along the guide rod 3 towards the side of pipe fitting 5, and the upper roller 45 and the lower roller 11 cooperate to clamp pipe fitting 5. At this time, pipe fitting 5 is pushed along its length direction, the upper roller 45 and the lower roller 11 rotate, and pipe fitting 5 moves along its length direction.

[0038] When the pipe fitting 5 is loosened, the electric telescopic rod 42 retracts. The retracted electric telescopic rod 42 pulls the drive link 23, which in turn pulls the upper self-locking link 21 and the lower self-locking link 22 to swing until the connecting block 43 contacts the upper fixed plate 41. During this process, the lower fixed plate 44 moves along the guide rod 3 away from the pipe fitting 5, and the upper roller 45 and the lower roller 11 move away from the loosened pipe fitting 5.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
