Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, specifically a fixture for processing hardware pipe fittings. Background Technology

[0002] Pipe fittings are tubular connections or functional components made of metal as raw material through casting, forging, stamping or machining. Common products include elbows, tees, crosses, reducers, pipe fittings, flanges, unions, plugs, pipe clamps, etc., which are widely used in fluid transportation pipeline systems.

[0003] In the processing of metal pipe fittings, clamps are typically used to reliably secure the fittings for operations such as cutting, beveling, grooving, or drilling. However, most existing pipe fitting clamps employ a fixed clamping structure, which, once locked, prevents rotation and adjustment of the fitting, making continuous cutting along the entire circumference difficult. When circumferential cutting or circumferential processing is required, operators often have to repeatedly loosen and manually rotate the fitting before re-locking it, which is time-consuming and results in low cutting efficiency. Therefore, this paper proposes a new type of clamp for metal pipe fitting processing to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fixture for processing hardware pipe fittings, which has the advantage of improving the cutting efficiency of pipe fittings and solves the problems of existing fixtures being unable to rotate and adjust pipe fittings and the need for repeated loosening and unloading during cutting operations, resulting in excessive time consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture for processing metal pipe fittings, including a base plate, wherein a pipe fitting fixing and rotating mechanism is provided on the base plate; The pipe fitting fixing and rotating mechanism includes two support seats and two support plates fixedly installed on the base plate. An installation plate is fixedly installed on the top of the support plate, and two electric telescopic rods are fixedly installed on the lower surface of the installation plate. An installation frame is fixedly installed on the output end of the electric telescopic rods, and a downward rotating component is provided on the installation frame. The top of the support is provided with a groove, and a support component is provided in the groove.

[0006] Furthermore, the downward rotating assembly includes two downward rollers rotatably mounted inside the mounting frame, and each of the two ends of the downward rollers is fixedly mounted with a first pulley; A motor is fixedly mounted on the outside of the mounting bracket, and a rotating shaft extending to the inside of the mounting bracket is fixedly mounted on the output end of the motor. Two second pulleys are fixedly mounted on the rotating shaft. The second pulley is connected to the corresponding first pulley via a belt drive.

[0007] Furthermore, the rotating shaft is located directly above the two lower pressure rollers, and each of the second pulleys is located directly above the corresponding first pulley.

[0008] Furthermore, the support assembly includes two first mounting slots rotatably mounted inside the groove, and a support roller is rotatably mounted inside the first mounting slot; A threaded rod is rotatably installed in the groove, and two second mounting slots are threadedly connected to the threaded rod. Slide rails are fixedly installed on the opposite sides of the inner surfaces of the second mounting slots. One end of the first mounting groove is located inside the second mounting groove, and a connecting block that slides and engages with the slide rail is fixedly mounted at that end.

[0009] Furthermore, the two first mounting slots are inclinedly disposed within the groove, and the included angle between the two first mounting slots is an acute angle.

[0010] Furthermore, there are multiple support rollers, which are evenly distributed along the length of the first mounting groove.

[0011] Furthermore, the thread on the surface of the threaded rod consists of a left-hand thread segment and a right-hand thread segment, and the two second mounting grooves are respectively threadedly connected to the left-hand thread segment and the right-hand thread segment.

[0012] Furthermore, the downward rotating assembly is located between the two supporting assemblies.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects: This hardware pipe fitting processing fixture integrates a support component and a downward rotating component through a base plate, realizing the integrated clamping and rotation drive of the hardware pipe fitting. The electric telescopic rod can drive the downward rotating component to rise and fall to adapt to different pipe diameters and apply downward pressure, forming a reliable fixation with the support component. At the same time, the downward rotating component can actively drive the pipe fitting to rotate, avoiding the repeated tightening and loosening and manual pipe rotation operations required by traditional fixtures, thereby significantly improving the efficiency of pipe fitting circumferential cutting or continuous circumferential processing.

[0016] 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.

[0017] Please see Figures 1 to 3 A hardware pipe fitting processing fixture in this embodiment includes a base plate 1, on which a pipe fitting fixing and rotating mechanism is provided; the pipe fitting fixing and rotating mechanism includes two support seats 2 and two support plates 3 fixedly installed on the base plate 1, a mounting plate 4 fixedly installed on the top of the support plate 3, two electric telescopic rods 5 fixedly installed on the lower surface of the mounting plate 4, a mounting frame 6 fixedly installed at the output end of the electric telescopic rods 5, and a downward rotating component 7 is provided on the mounting frame 6; a groove 8 is opened on the top of the support seat 2, and a support component 9 is provided in the groove 8.

[0018] In this embodiment, the downward pressure rotation assembly 7 includes two downward pressure rollers 71 rotatably mounted inside the mounting frame 6. Each end of the downward pressure roller 71 is fixedly mounted with a first pulley 72. A motor 73 is fixedly mounted on the outside of the mounting frame 6. A rotating shaft 74 extending into the inside of the mounting frame 6 is fixedly mounted at the output end of the motor 73. Two second pulleys 75 are fixedly mounted on the rotating shaft 74. The second pulleys 75 are connected to their corresponding first pulleys 72 via a belt 76. Through the transmission cooperation of the motor 73, rotating shaft 74, first pulleys 72, second pulleys 75, and belt 76, the two downward pressure rollers 71 can be driven to rotate synchronously. The two downward pressure rollers 71 can both press the pipe from above and drive the pipe to rotate circumferentially through the friction generated by their rotation.

[0019] It should be noted that the rotating shaft 74 is located directly above the two lower pressure rollers 71, and each second pulley 75 is located directly above the corresponding first pulley 72.

[0020] In this embodiment, the supporting component 9 includes two first mounting grooves 91 rotatably mounted inside the groove 8, with a supporting roller 92 rotatably mounted inside the first mounting groove 91; a threaded rod 93 is rotatably mounted inside the groove 8, and two second mounting grooves 94 are threadedly connected to the threaded rod 93; slide rails 95 are fixedly mounted on opposite sides of the inner surfaces of the second mounting grooves 94; one end of the first mounting groove 91 is located inside the second mounting groove 94, and a connecting block 96 that slides with the slide rail 95 is fixedly mounted at that end. This facilitates the support of the pipe fitting and also allows for the rotation of the pipe fitting.

[0021] It should be noted that the two first mounting grooves 91 are inclinedly arranged within the groove 8, and the included angle between the two first mounting grooves 91 is an acute angle. The two first mounting grooves 91 arranged at an acute angle and their supporting rollers 92 together form a V-shaped or approximately V-shaped supporting surface, which facilitates automatic centering of the circular tube during placement, limits the lateral displacement of the tube, improves clamping stability, and facilitates a stable three-point contact clamping with the upper lower pressure roller 71.

[0022] It should be noted that there are multiple support rollers 92, which are evenly distributed along the length of the first mounting groove 91. The multiple evenly distributed support rollers 92 transform the sliding friction between the pipe and the support surface into rolling friction, which significantly reduces the frictional resistance when the pipe rotates, making the downward rotating assembly 7 drive the pipe to rotate more smoothly and easily, while reducing scratches on the pipe surface.

[0023] It should be noted that the thread on the surface of the threaded rod 93 consists of a left-hand thread segment and a right-hand thread segment, and the two second mounting slots 94 are threadedly connected to the left-hand thread segment and the right-hand thread segment, respectively. By rotating the threaded rod 93, the two second mounting slots 94 can be driven to move towards or away from each other. In turn, through the sliding engagement of the connecting block 96 and the slide rail 95, the tilt angle or spacing of the two first mounting slots 91 and their supporting rollers 92 can be adjusted synchronously. This can accommodate pipes of different diameters and ensure that the supporting rollers 92 always form good rolling contact with the surface of the pipe.

[0024] It should be noted that the downward rotating assembly 7 is located between the two supporting assemblies 9. The downward rotating assembly 7 is arranged between the two supporting assemblies 9, forming a layout of supporting at both ends and pressing and driving in the middle. This helps to distribute the gravity and clamping force of the pipe fitting, avoid bending and deformation of the pipe fitting, and at the same time, it enables the driving torque to be transmitted evenly, improving the stability of the pipe fitting rotation and the processing accuracy.

[0025] It should be noted that in this embodiment, the two electric telescopic rods 5 are precisely controlled by a programmable logic controller, and the synchronous movement of the two electric telescopic rods 5 is achieved through programming.

[0026] The working principle of the above embodiments is as follows: The operator manually rotates the threaded rod 93 according to the diameter of the hardware fitting to be processed. The surface of the threaded rod 93 consists of a left-hand threaded section and a right-hand threaded section. Two second mounting grooves 94 are respectively connected to the two threaded sections. When rotating, the two second mounting grooves 94 move synchronously towards or away from each other. The interior of each second mounting groove 94 is slidably engaged with the connecting block 96 through the slide rail 95, thereby driving the corresponding first mounting groove 91 to change the tilt angle, so that the included angle between the two first mounting grooves 91 forms a V-shaped support structure. The support roller 92 on the inner side of the first mounting groove 91 is used to directly contact the outer wall of the fitting to achieve rolling support. Then, the hardware fitting is placed on top of the two support seats 2, so that it naturally falls on the support rollers 92 on both sides.

[0027] Since the downward rotating assembly 7 is located between the two supporting assemblies 9, the mounting frame 6 is located above the middle of the pipe fitting. When the two electric telescopic rods 5 fixed to the lower surface of the mounting plate 4 are activated, the output ends of the two electric telescopic rods 5 extend downward synchronously, pushing the mounting frame 6 down, so that the two downward pressure rollers 71 press against the surface of the pipe fitting. At this time, the pipe fitting is reliably clamped between the supporting roller 92 and the two downward pressure rollers 71, forming a three-point contact fixation. When it is necessary to perform circumferential cutting, grooving or drilling along the circumference of the pipe fitting, the motor 73 is activated, and its output end drives the rotating shaft 74 to rotate, so that the two second pulleys 75 rotate synchronously. Each second pulley 75 is connected to the first pulley 72 at the end of the corresponding downward pressure roller 71 through the belt 76, so that the two downward pressure rollers 71 rotate synchronously in the same direction. Through friction, the pipe fitting rotates on the supporting roller 92. The operator can perform uninterrupted processing during the continuous rotation of the pipe fitting. After the processing is completed, the motor 73 is stopped, the electric telescopic rods 5 are retracted, the mounting frame 6 and the downward pressure rollers 71 are lifted, and the pipe fitting can be removed.
