Description

Technical field:

[0001] The present application relates to the technical field of workbench welding, and in particular to an anti-deformation welding positioner. Background technology:

[0002] In daily welding work, as long as welding is done, plastic deformation of the parent material will be caused, especially in structures where the welds are asymmetrically distributed and concentrated on one side. For example, in the welding structure of a workbench, the welds are concentrated on one side. During the welding process, due to the concentration of heat, the table top will be high in the middle and low at the four corners, with a deformation of 3-8mm. After each piece is welded, the workbench needs to be flattened by a large press, which is time-consuming, labor-intensive, and has a complicated process. In addition, there is a risk of weld cracking during the shaping process, which will cause irreversible damage to the entire welded part and, in severe cases, will cause the welded part to be scrapped.

[0003] The Chinese National Utility Model Patent with application number 201020548293.4 is an anti-deformation / pre-deformation welding positioner for an excavator supporting wheel bracket, which includes a support, which is driven to flip by a driving shaft and a driven shaft on the left and right sides. The driving shaft is driven by a driving device. A cylinder is provided in the middle of the support, and the cylinder is connected to an external hydraulic pump station. A first pad is provided between the cylinder and the workpiece to be operated, and two slide plates are provided on both sides of the top of the support, respectively. A clamping seat is provided between the two slide plates, and the clamping seat can move longitudinally on the slide plate. A pressure plate is passed through the clamping seat, and the pressure plate is supported by a support member. A second pad is provided below the top of the pressure plate.

[0004] The patent uses a clamping seat to fix the support wheel bracket, and then uses a cylinder for correction. However, the clamping seat can move longitudinally on the slide plate, so it is impossible to determine whether the center axis of the support wheel bracket coincides with the center axis of the cylinder, and multiple adjustments are required for correction, which is time-consuming and labor-intensive, and seriously affects the correction efficiency. Utility model content:

[0005] In order to solve the above technical problems, the utility model provides an anti-deformation welding positioner, which solves the technical problem that multiple adjustments are required for correction, which is time-consuming and labor-intensive, and seriously affects the correction efficiency.

The specific implementation scheme of the utility model is as follows:

[0030] A reverse deformation welding positioner comprises a positioner body 1, a clamping piece 2 is arranged on the upper end surface of the table of the positioner body 1, X-direction clamping blocks 4 are symmetrically arranged on both sides of the clamping piece 2 in the X direction in a sliding structure manner, and Y-direction clamping blocks 5 are symmetrically arranged on both sides of the clamping piece 2 in the Y direction in a sliding structure manner, the X-direction clamping blocks 4 and the Y-direction clamping blocks 5 are both connected to the table of the positioner body 1 in a sliding structure manner, and a power device for driving the X-direction clamping block 4 or the Y-direction clamping block 5 to move is also arranged, and the power device is connected to the positioner body 1; the clamping piece is fixed in the center of the running track of the two X-direction clamping blocks and the Y-direction clamping block, and the center of the workbench is moved to the top of the clamping piece by using the clamping block, so as to reduce the number of adjustments, improve work efficiency and ensure the accuracy of correction.

[0031] Specifically, in this embodiment, the tensioning member 2 is a cylindrical structural pad, and the pad is fixedly connected to the positioner body 1; in other embodiments, the tensioning member 2 may also be a hydraulic cylinder.

[0032] It should be noted that the clamping device 3 includes an L-shaped support seat 31, which can meet the correction of the workbench within a certain size range, thereby increasing practicality; a slideway 32 is provided in the L-shaped support seat 31, and a T-shaped slider 33 is provided in the slideway 32 in a sliding structure manner, and the T-shaped slider 33 is provided with a bolt 34 through a threaded engagement manner, and a clamping plate 35 is provided on the outside of the bolt 34. Through the engagement of the bolt 34 with the T-shaped slider 33, the workbench is pressed against the end face of the L-shaped support seat 31 using the clamping plate 35.

[0033] It should be explained that two sets of power devices are arranged along the X direction or the Y direction, and are symmetrically arranged on both sides of the clamping member 2, so that the X-direction clamping block 4 and the Y-direction clamping block 5 form a running track of a tic-tac-toe structure.

[0034] Specifically, the power device is a double-slider linear slide 6, which is connected to the table of the positioner body 1 in a fixed structure. The double-slider linear slide 6 includes a linear guide 61, a positive and negative thread screw 62, a handwheel 63 and two sliders 64. The linear guide 61 and the two sliders 64 are connected in a sliding structure. The two sliders 64 are respectively connected to the positive thread and the negative thread of the positive and negative thread screw 62 through threaded engagement, and one end of the positive and negative thread screw 62 is connected to the handwheel 63 in a fixed structure. It should be noted that the positive and negative thread screw 62 is connected to the table of the positioner body 1 through a bearing seat, and the linear guide 61 is connected to the table of the positioner body 1.

By setting a double-slider linear slide 6, it is used to drive the X-direction clamping block or the Y-direction clamping block to move relative or toward each other, so as to ensure that the workbench moves more lightly and smoothly.

[0035] The working principle and working process of the utility model are as follows:

[0036] First, the welded workbench is hoisted to a horizontal plane below the L-shaped support seat 31 by a crane.

[0037] The hand wheel 63 in the X direction is turned, and the hand wheel 63 drives the two sliders 64 to move toward each other through the forward and reverse screws 62. The sliders 64 drive the X-direction clamping blocks 4 to move toward each other, thereby driving the Y-direction center axis of the workbench to coincide with the Y-direction center axis of the clamping member 2.

[0038] The hand wheel 63 in the Y direction is rotated to drive the Y-direction clamping block 5 to move toward each other, thereby driving the X-direction center axis of the workbench to coincide with the X-direction center axis of the clamping member 2.

[0039] Place one end of the clamping plate 35 on the end surface of the workbench, turn the bolt 34, and use the clamping plate 35 to clamp the workbench on the L-shaped support seat 31 to weld the internal components. After welding, no shaping is required, which reduces the process steps and thus reduces the manufacturing cost.
