Technical Field

[0001] The utility model belongs to the technical field of welded pipe production equipment, in particular to a clamping and fixing device for welded pipe production. Background Art

[0002] With the development of science and technology, welding technology has gradually matured. In terms of welded steel pipes, it refers to steel pipes with seams on the surface that are made by bending steel strips or steel plates into round, square and other shapes and then welding them. However, when welded pipes need to be welded during the processing process, they need to be clamped and fixed to avoid shaking during the welding process and affecting the welding effect. Therefore, a clamping and fixing device for welded pipe production is needed.

[0003] A Chinese patent application with publication number CN219787152U discloses a clamping and fixing device for square tube welding; it includes two first brackets, a second bracket, a third bracket and a base plate, and the first bracket, the second bracket and the third bracket respectively have a plurality of positioning holes, the end face of the base plate has a slide groove, the two first brackets are respectively fixedly connected to the base plate and symmetrically arranged on the end face of the base plate, the second bracket is slidably connected to the base plate and is located in the slide groove, the third bracket is slidably connected to the base plate and is located at one end of the slide groove away from the second bracket, and the second bracket and the third bracket are symmetrically arranged, and the square tube assembly rack is clamped and fixed on the base plate through the cooperation of the first bracket, the second bracket and the third bracket, which effectively solves the problem that the traditional process requires continuous measurement and adjustment of positioning, which is time-consuming and labor-intensive, has low efficiency and is not suitable for mass production.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The above-mentioned clamping and fixing device for square tube welding is clamped through the outer wall of the welded tube, but the outer wall of the welded tube may be damaged during the clamping process, and the processing is relatively inconvenient;

[0006] 2. The above-mentioned clamping and fixing device for square tube welding can only judge different processing positions based on the experience of employees, and cannot accurately adjust the processing position of the welded tube to the required position, thereby reducing the practicality.

[0007] To this end, we provide a clamping and fixing device for welded pipe production to solve the above-mentioned problems. Utility Model Content

[0008] The utility model aims to provide a clamping and fixing device for welded pipe production, which can quickly clamp welded pipes of different sizes through a clamping component, while avoiding the situation where indentations or wear are caused to the welded pipe during the clamping process; the processing position of the clamped welded pipe can be adjusted through an adjusting component, thereby reducing the steps required for subsequent measurement during processing, improving work efficiency, and solving the problems of existing clamping and fixing devices for welded pipe production.

[0009] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0010] The utility model is a clamping and fixing device for welding pipe production, comprising a base, a controller, a scale and a distance measuring plate. The front end of the base is equipped with a controller, the upper side wall of the base is inlaid with a scale, the upper side wall of the base is detachably fixedly connected with the distance measuring plate, the upper side wall of the base is symmetrically provided with two clamping components, and the upper side wall of the base is equipped with an adjusting component; the outer side wall of the mounting column of the clamping component is circumferentially equipped with a fixing spring, the moving end of the fixing spring is equipped with an arc-shaped clamping plate, and the surface of the arc-shaped clamping plate is equipped with a rubber pad; the protruding end of the electric telescopic rod of the adjusting component is equipped with a connector, the left side wall of the connector is equipped with a slider, the upper side wall of the slider is equipped with a mounting plate, the left side wall of the mounting plate is equipped with a supporting plate, and the upper side wall of the supporting plate is equipped with an infrared rangefinder.

[0011] The utility model is further configured that a sliding groove is provided on the upper side wall of the base, a sliding block is installed in the sliding groove of the base, and the base is slidably connected with the sliding block through the sliding groove.

[0012] The utility model is further configured such that the right side wall of the slider is detachably fixedly connected to the connector, the left side wall of the connector is detachably fixedly connected to the moving end of the electric telescopic rod, and the fixed end of the electric telescopic rod is detachably fixedly connected to the base.

[0013] The utility model is further configured that the input end of the electric telescopic rod is electrically connected to the output end of the controller, and the controller is connected to the infrared rangefinder through a wire.

[0014] The utility model is further configured that the lower side wall of the infrared rangefinder is detachably fixedly connected to the support plate, and the output end of the infrared rangefinder is opposite to the rangefinder plate.

[0015] The utility model is further configured such that the right side wall of the support plate is detachably fixedly connected to the mounting plate, and the lower side wall of the mounting plate is detachably fixedly connected to the sliding block.

[0016] The utility model is further configured such that the left side wall of the mounting plate is detachably fixedly connected to the mounting column, and the outer side wall of the mounting column is detachably fixedly connected to the fixed end of the fixing spring.

[0017] The utility model is further configured that the moving end of the fixed spring is detachably fixedly connected to the arc-shaped clamping plate, and the surface of the arc-shaped clamping plate is fittedly connected to the rubber pad.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model sets a clamping assembly, and brings the rubber pads around the mounting column of the clamping assembly closer to the center. The arc-shaped clamping plate will compress the fixed spring in the process of moving closer to the center, so as to put one end of the welded pipe on. When the arc-shaped clamping plate is loosened, the arc-shaped clamping plate is pushed to expand outwards on all sides under the reaction force of the fixed spring, so as to clamp the inner wall of the welded pipe. At the same time, the rubber pad can increase the friction while playing a protective role, so as to achieve a better clamping effect. When the electric telescopic rod at the other end is controlled to drive the clamping assembly to move, the other end of the welded pipe is clamped in the same manner as above, so that the two ends of the welded pipes of different lengths can be fixed, thereby solving the problem that the outer wall of the welded pipe may be damaged during the clamping process and the processing is inconvenient.

[0020] 2. The utility model sets an adjustment component. After clamping the welded pipe, the distance between the leftmost end of the welded pipe and the processing position is measured by a ruler. The infrared rangefinder is turned on to measure the distance to the distance measuring plate, and the required moving distance of the welded pipe is calculated. The controller controls one electric telescopic rod to extend and the other to retract, so as to achieve the effect of synchronous movement, thereby driving the clamped welded pipe to move horizontally. The infrared rangefinder measures the distance between the distance measuring plates at all times and feeds back to the controller. When the required movement distance is reached, the movement of the two electric telescopic rods is stopped immediately, so as to adjust the processing position to the required position, which is convenient for subsequent processing and solves the problem that different processing positions can only be judged by employee experience, and the processing position of the welded pipe cannot be accurately adjusted to the required position, thereby reducing practicality.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Specific embodiment 1

[0032] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model is a clamping and fixing device for welding pipe production, including a base 1 and a controller 101 installed at the front end of the base 1, and two clamping components 2 are symmetrically arranged on the upper side wall of the base 1. The two clamping components 2 can clamp the inner walls of the two ends of the welding pipe, solving the problem that the existing clamping causes damage to the outer wall of the welding pipe.

[0033] Specifically, the outer wall of the mounting column 201 of the clamping assembly 2 is circumferentially and detachably fixedly connected to the fixed end of the fixed spring 202. The mounting column 201 facilitates the installation of the fixed spring 202. The moving end of the fixed spring 202 is detachably and fixedly connected to the arc-shaped clamping plate 203. The arc-shaped clamping plate 203 can clamp the inner wall of the welding pipe. The surface of the arc-shaped clamping plate 203 is fitted and connected to the rubber pad 204, and the rubber pad 204 can protect the welding pipe.

[0034] Furthermore, the right side wall of the mounting column 201 is detachably fixedly connected to the mounting plate 304, and the mounting plate 304 plays a supporting role and can fix the mounting column 201 so that the mounting column 201 can achieve a better installation effect.

[0035] The operation process of this embodiment is: the rubber pad 204 around the mounting column 201 of the clamping assembly 2 is moved closer to the center, and the arc-shaped clamping plate 203 will compress the fixed spring 202 in the process of moving closer to the center, so as to facilitate the sleeve of one end of the welding pipe, and then release the arc-shaped clamping plate 203, and push the arc-shaped clamping plate 203 to expand outwards around under the reaction force of the fixed spring 202, so as to clamp the inner wall of the welding pipe, and at the same time, the rubber pad 204 can increase the friction force while playing a protective role, so as to achieve a better clamping effect, and control the electric telescopic rod 301 at the other end to drive the clamping assembly 2 to move, and perform the same operation as above to clamp the other end of the welding pipe, so as to complete the fixing of both ends of welding pipes of different lengths. Specific embodiment 2

[0037] See also Figure 1 , Figure 2 and Figure 3 On the basis of the specific embodiment 1, the upper side wall of the base 1 is also inlaid with a scale 102, which is convenient for measuring the processing position of the welded pipe. The upper side wall of the base 1 is detachably fixedly connected to the distance measuring plate 103, and the distance measuring plate 103 is convenient for the subsequent adjustment of the processing position of the welded pipe. The adjustment component 3 is installed on the upper side wall of the base 1. The adjustment component 3 can accurately adjust the processing position of the welded pipe, which is convenient for subsequent processing and solves the problem of inconvenience in adjusting the existing processing position.

[0038] Specifically, the extended end of the electric telescopic rod 301 of the adjustment component 3 is detachably fixedly connected to the connector 302, and the connector 302 plays a connecting effect. The left side wall of the connector 302 is detachably fixedly connected to the slider 303, and the slider 303 facilitates the movement of the mounting plate 304. The upper side wall of the slider 303 is detachably fixedly connected to the mounting plate 304, and the mounting plate 304 plays an effect of facilitating the installation of the infrared rangefinder 305.

The upper side wall of the support plate 305a is detachably fixedly connected to the infrared rangefinder 305, and the infrared rangefinder 305 is fixed to better work.

[0039] Furthermore, a slider 303 is installed in the slide groove 104 opened on the upper side wall of the base 1, and the slide groove 104 can limit the movement trajectory of the slider 303. The base 1 is slidably connected to the slider 303 through the slide groove 104, which facilitates the movement of the slider 303. At the same time, the fixed end of the electric telescopic rod 301 is detachably fixedly connected to the base 1, and the electric telescopic rod 301 is fixed to better promote the movement of the slider 303. The input end of the electric telescopic rod 301 is electrically connected to the output end of the controller 101 to facilitate the control of the movement of the electric telescopic rod 301. The controller 101 is connected to the infrared rangefinder 305 through a wire, so that the value measured by the infrared rangefinder 305 can be fed back to the controller 101 at all times, and the output end of the infrared rangefinder 305 is opposite to the distance measuring board 103, so that the infrared rangefinder 305 can measure the distance to the distance measuring board 103 at all times.

[0040] The operation process of this embodiment is as follows: after clamping the welding pipe, the distance between the leftmost end of the welding pipe and the processing position is measured by the scale 102, and the distance to the distance measuring plate 103 is measured by turning on the infrared rangefinder 305, and the required moving distance of the welding pipe is calculated. The controller 101 controls one electric telescopic rod 301 to extend and the other to retract, so as to achieve the effect of synchronous movement, thereby driving the clamped welding pipe to move horizontally, and the distance between the distance measuring plates 103 is measured at all times by the infrared rangefinder 305 and fed back to the controller 101. When the required movement distance is reached, the movement of the two electric telescopic rods 301 is stopped immediately, so as to adjust the processing position to the required position, so as to facilitate subsequent processing.
