Description

Technical Field

[0001] This utility model relates to the field of metal parts processing technology, specifically to a tooling fixture for processing tubular parts. Background Technology

[0002] Metal pipe coating is a composite pipe with steel pipe as the base pipe and plastic powder (such as epoxy resin) as the coating material. A plastic layer is coated on the inner surface and a plastic layer or other anti-corrosion material is coated on the outer surface. The coated steel pipe is also called plastic-coated steel pipe.

[0003] In existing coating equipment, most methods use clamping devices to fix the ends of the tube, and then use telescopic structures to extend it into the coating chamber. The surface is then coated by spraying. During this process, the tube body needs to be rotated simultaneously to ensure that the surface of the metal tube is completely covered. However, in actual use, especially when coating some long metal tubes, relying on only one side of the support will cause the entire tube body to be unstable. Furthermore, this single-sided clamping production method requires frequent replacement of the metal tube, resulting in low coating efficiency and failing to meet the growing production demands. Utility Model Content

[0004] Based on the above description, this utility model provides a tooling fixture for processing tubular parts, which solves the shortcomings of existing metal tube coating equipment that relies on clamping the tube on only one side, which cannot guarantee the stability of its operation, and is also complicated to operate and has low production efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] A tooling fixture for machining tubular parts includes a base and a coating box fixed on the base. The coating box has connecting seats on both sides and a fixing component on the top of the connecting seats. One set of fixing components has a metal tube, the other end of which passes through the coating box and is inserted into the center of the other set of fixing components. The base also has a pushing component, the telescopic end of which is in contact with the end face of the metal tube and pushes it toward the coating box.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the coating box is rectangular with circular through holes on both sides, and a nozzle is provided inside the coating box. A storage chamber is provided on the top of the coating box, and the nozzle is connected to the storage chamber through a delivery pipe, with a pressure pump provided at the connection point.

[0009] Furthermore, the connecting seat is rectangular, and a horizontal groove is arranged on the top surface of the base. The connecting seat is slidably assembled inside the groove, and multiple positioning holes are arranged at intervals on the bottom surface of the groove. The connecting seat is provided with corresponding through holes and is locked and fixed with bolts. A connecting rod is vertically arranged on the top of the connecting seat, and a ring-shaped mounting bracket is provided on the top of the connecting rod.

[0010] Furthermore, the fixing component includes a locking disc movably mounted at the center of the mounting frame, and a ball bearing seat is provided between the outer ring surface of the locking disc and the inner ring surface of the mounting frame. The locking disc has a through hole at its center and multiple limiting grooves are arranged around it. Each limiting groove contains a locking block, and the multiple locking blocks extend towards the center and converge.

[0011] Furthermore, each of the card blocks has a guide roller movably mounted at its end, and the surface of the guide roller is covered with an elastic pad, the surface of which is in close contact with the side wall of the metal tube.

[0012] Furthermore, an adjusting ring is movably installed inside the locking disc. The adjusting ring has an arc-shaped groove, and the bottom of the locking block has a protrusion that passes inward through the limiting groove and is inserted into the arc-shaped groove.

[0013] Furthermore, a drive ring is provided on the back of the adjusting ring, and the surface of the drive ring is provided with a toothed portion. An adjusting handle is rotatably mounted on the side wall of the locking disc. The output end of the adjusting handle extends inward and is provided with a gear at the end. The gear engages with the toothed portion on the surface of the drive ring.

[0014] Furthermore, a drive wheel is provided on one end face of the locking disc, and a drive motor is provided on the mounting bracket. The output end of the drive motor faces vertically downward and has a toothed sleeve at the bottom end. The toothed sleeve is engaged with the drive wheel.

[0015] Furthermore, the pushing assembly includes an electric push rod disposed on one side of the top surface of the base, and a rectangular baffle is movably mounted on the end of the electric push rod via a bearing seat, the end face of the rectangular baffle being tightly fitted with the end face of the metal tube.

[0016] Furthermore, an observation window is provided on the surface of the coating box.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] This application improves upon existing metal pipe coating equipment by using a fixed component to clamp the metal pipe, allowing it to rotate via a drive structure on the connecting seat while remaining fixed. This effectively coordinates with the spraying equipment inside the coating box to coat the pipe surface. Simultaneously, the pipe can move horizontally within the fixed component, enabling continuous feeding and using subsequent metal pipes to move the preceding ones. Compared to traditional coating equipment, this method is suitable for coating pipes of various lengths and sizes, offers greater stability, significantly improves production efficiency and quality, and is highly convenient to use.

[0026] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0028] Combination Figure 1-6 As shown, a tooling fixture for machining tubular parts includes:

[0029] Base 1 serves as the mounting foundation for the entire coating equipment and is placed on the ground or workbench.

[0030] The coating box 2 is rectangular and has circular through holes on both sides. The coating box 2 is also equipped with a nozzle inside. The top of the coating box 2 is equipped with a storage chamber. The nozzle is connected to the storage chamber through a delivery pipe and a pressure pump is provided at the connection point.

[0031] Connector 3 is slidably mounted on the top surface of base 1, and is equipped with one or more depending on the length of the pipe, for auxiliary support of the pipe;

[0032] The fixing component 4 is located on the top of the connecting seat 3 and is used to clamp and fix the pipe while allowing it to move horizontally.

[0033] The pushing component 5 is located on the top surface of the base 1 and is arranged away from the coating box 2. It is used to push the end of the metal tube so that it moves towards the coating box 2.

[0034] Specifically, in this embodiment, the base 1 is also provided with a sliding groove, which is divided into two groups and arranged on both sides of the coating box 2 to assist the connecting seat 3 in sliding adjustment, thereby adjusting the spacing between the connecting seats 3 according to the length of the pipe. Especially when coating long metal pipes, it ensures that the length of the section entering the coating box 2 is less than the length outside, so that the metal pipe is more stable during the coating process.

[0035] In addition, in order to facilitate the fixing of the connecting seat 3 after it has been adjusted inside the slide, positioning holes should be arranged at intervals on the bottom surface of the slide. These positioning holes are bolt holes. At the same time, through holes are provided on the bottom surface of the connecting seat 3. The bolts are vertically inserted into the through holes and locked and fixed through the bolt holes.

[0036] The bottom of the connector 3 is rectangular, and a connecting shaft is vertically arranged at the center of the top surface. A ring-shaped mounting bracket 31 is provided on the top of the connecting shaft, and a fixing component 4 is installed at the center of the mounting bracket 31.

[0037] The fixing component 4 includes a locking disc 41, an adjusting ring 42, and a limiting groove 44. The outer ring surface of the locking disc 41 is provided with a ball bearing seat, and the structure is used to movably connect with the mounting bracket 31, so the entire locking disc 41 can rotate flexibly.

[0038] The locking disc 41 is circular with a through hole in the center to assist in the transport of metal pipes. Three limiting grooves 43 are provided on one side of its end face. Each limiting groove 43 contains a slidingly mounted limiting groove 44. The limiting groove 44 is rectangular in shape, extending towards the center at its top. A guide roller 45 is movably mounted at the top of the guide roller 45. Figure 4 The structure shown has an arc-shaped surface covered with a rubber pad. The surfaces of the three guide rollers 45 are simultaneously in contact with the surface of the metal tube, ensuring that the metal tube can be conveyed horizontally while being clamped and fixed.

[0039] The adjusting ring 42 is disposed inside the locking disc 41, and the adjusting ring 42 is concentrically arranged with the locking disc 41 and has an arc-shaped groove on its surface. The arc-shaped groove is arranged in a spiral structure, for example... Figure 5 As shown, the bottom of the limiting groove 44 has a protrusion that extends along the side wall of the limiting groove 43 into the interior of the locking disc 41, and cooperates with the arc-shaped groove to form a chuck drive structure. When the adjusting ring 42 rotates, it can simultaneously drive the three limiting grooves 44 to converge towards the center or cause the three limiting grooves 44 to expand outwards at the same time. The operator can use this adjustment method to cope with the coating of metal pipes of different sizes.

[0040] A drive structure should also be provided on the back of the adjusting ring 42. Therefore, a drive ring is also provided on the back of the adjusting ring 42. A toothed portion is provided on the end face of the drive ring. An adjusting handle 46 is rotatably mounted on the side wall of the locking disc 41. The output end of the adjusting handle 46 extends inward and is provided with a gear at the end, which meshes with the toothed portion on the surface of the drive ring.

[0041] In addition to clamping and fixing the metal pipe, the above structure also needs to rotate the metal pipe to ensure that the spray nozzle can cover the surface of the metal pipe inside the coating box 2. Therefore, a drive wheel should be provided on the side of the locking disc 41 away from the limiting groove 43. A drive motor 47 is provided on the mounting bracket 31. The output end of the drive motor 47 is vertically downward and a toothed sleeve is provided at the bottom. The toothed sleeve is engaged with the drive wheel to drive the entire locking disc 41 to rotate in a specific direction.

[0042] The pushing component 5 is an electric push rod located on one side of the top surface of the base 1. A rectangular baffle is movably mounted on the end of the electric push rod through a bearing seat. The end face of the rectangular baffle is tightly fitted with the end face of the metal tube and pushes the metal tube forward at a uniform speed. An auxiliary bracket can also be provided between the pushing component 5 and the connecting seat 3, which is concentrically arranged with the fixing component 4 to assist in feeding. This allows the tube to be directly placed in the bracket and automatically aligned with the fixing component 4, thereby using the electric push rod to transport it, further simplifying its operation and layout.

[0043] Based on this, workers can also add a traction mechanism at the other end, that is, the end opposite to the push component 5, to use a robotic arm (or other clamping structure) to clamp the coated pipe end and pull it to continue moving so as to remove the entire pipe.

[0044] An observation window should also be provided on the surface of the coating box 2 so that the staff can control the speed of the pipe according to the actual coating effect, and avoid the pipe surface being not completely covered due to excessive speed.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
