[0018] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0019] Reference Figures 1 to 4 The utility model provides a telescopic positioning device for pipe processing, including a processing table 1, a translation assembly is arranged on the top of the processing table 1, and the translation assembly includes a support frame 6 slidably connected to the top of the processing table 1, a slider 5 fixed to the bottom of the support frame 6, a slide rail 3 fixed to the top of the processing table 1 and matched with the slider 5, a first motor 2 installed on one side of the processing table 1, and a first screw rod 4 fixed to the output end of the first motor 2, the first screw rod 4 passes through the bottom of the support frame 6 and forms a threaded transmission with the support frame 6.

[0020] Furthermore, if Figure 2 , Figure 4As shown, in the utility model, a clamping assembly 2 is arranged in the translation assembly, and the clamping assembly 2 includes an arc-shaped clamping plate 8 and a telescopic rod symmetrically arranged in the upper and lower parts, a second screw 13 threadedly connected to the top of the support frame 6, and a limit plate 12 rotatably connected to the bottom of the second screw 13, the telescopic rod includes a sleeve 7, a pillar 10 and a spring 9, the spring 9 is fixedly connected to the inside of the sleeve 7, the pillar 10 is fixedly connected to the end of the spring 9 away from the sleeve 7, the inner side of the support frame 6 is symmetrically provided with grooves 25 matching the limit plate 12, and a roller needle 11 is rollingly arranged on the inner side of the arc-shaped clamping plate 8. Specifically, one end of the pipe fitting is placed between the upper and lower groups of arc-shaped clamping plates 8, and the second screw 13 is rotated downward to push the limit plate 12 to slide downward in the groove 25, so that the upper arc-shaped clamping plate 8 moves downward, and cooperates with the lower arc-shaped clamping plate 8 to make the spring 9 in the telescopic rod in an extruded state, thereby firmly clamping one end of the pipe fitting to prevent it from falling due to external force during pipe processing. At the same time, the setting of several roller needles 11 facilitates the flipping of the pipe fitting.

[0021] Furthermore, if Figure 3 As shown, a clamping assembly 1 is fixedly connected to one side of the processing table 1 in the utility model, and the clamping assembly 1 includes a protective shell 14 fixedly connected to the top of the processing table 1, a rotating wheel 22 rotatably arranged in the protective shell 14, an electric push rod 24 fixedly connected to the inner side of the rotating wheel 22, and a driving assembly arranged on one side of the rotating wheel 22. Guide grooves 15 are symmetrically arranged on the inner side of the protective shell 14, and protrusions 16 matching the guide grooves 15 are arranged on the outer walls on both sides of the rotating wheel 22. The protrusions 16 are ring-shaped, and 4 groups of electric push rods 24 are annularly arranged. A rubber pad 26 is arranged at the end of the electric push rod 24, and the driving assembly includes a ring gear 23 fixedly connected to the outer side of the rotating wheel 22, a first gear 20 and a second gear 21 respectively meshed on both sides of the ring gear 23, a worm wheel 18 coaxially connected to the first gear 20, a worm 17 meshed with the worm wheel 18, and a second motor 19 fixedly connected to the bottom of the worm 17. Specifically, the end of the pipe away from the support frame 6 is placed on the electric push rod 24, and the electric push rod 24 is driven to clamp the pipes of different diameters so that the rubber pad 26 contacts the surface of the pipe; the second motor 19 is started to drive the worm 17 to rotate, the worm 17 drives the worm wheel 18 to rotate, and the worm wheel 18 drives the first gear 20 to rotate coaxially, and the first gear 20 is meshed with the ring gear 23, thereby driving the rotating wheel 22 to rotate; at the same time, the protrusion 16 cooperates with the guide groove 15 to provide a guiding effect for the rotation of the rotating wheel 22, and the second gear 21 is meshed with the ring gear 23 to ensure the stability and smoothness of the pipe flipping.

[0022] It should be noted that the helix angle of the worm 17 in the present invention is smaller than the equivalent friction angle between the meshing teeth of the worm 17 and the worm wheel 18, so that the worm 17 and the worm wheel 18 can achieve a self-locking effect; the motor in the present invention adopts a brake motor, which is a motor equipped with an electromagnetic brake. When the motor is powered on, the electromagnetic brake is also powered on and attracted. At this time, it does not brake the motor. When the motor is powered off, it also powers off and brakes the motor, so that the motor has a self-locking function. Double self-locking is achieved by the worm wheel 18, the worm 17, and the motor. After the motor is powered off, the rotating wheel 22 will not rotate under the action of external force and deadweight.

[0023] Working principle: When processing pipe fittings, start the first motor 2, slide the support frame 6 to a position suitable for processing the pipe fittings, place one end of the pipe fitting into the support frame 6, clamp the pipe fittings by the arc clamping plate 8, and then clamp the other end of the pipe fittings by the electric push rod 24, thereby realizing the retractable and positioning functions of the retractable positioning device for pipe fitting processing; when the pipe fitting needs to be rotated to process the other side, start the second motor 19, so that the rotating wheel 22 rotates in the protective shell 14, driving one end of the pipe fitting to rotate, and at the same time, the other end of the pipe fitting is clamped by the arc clamping plate 8, and the other end of the pipe fitting is rotated by the rolling of the needle roller 11, preventing the pipe fitting from being deformed due to external force factors during the rotation process, thereby realizing the rotation of the pipe fitting.

[0024] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
