Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a welding fixture with anti-deviation function. Background Technology

[0002] A welding fixture is a tool used to assist in positioning and fixing workpieces during the welding process. Its main function is to ensure the accuracy of the workpiece's position, angle, and orientation during welding, thereby improving the precision and quality of the weld. Welding fixtures are commonly used in automated production lines, especially in mass production and welding processes requiring high precision.

[0003] Authorized publication number CN214418057U discloses a welding device for steel structure processing with an anti-deviation mechanism, including a base plate. Columns are fixedly mounted on both upper sides of the base plate, and a top plate is fixedly mounted on the upper end of each column. Connecting rods are movably inserted through both sides of the inside of the top plate. A screw is movably screwed into the center of the inner side of the top plate via a thread. A fixed frame is movably mounted on the lower end of the screw via a bearing. The fixed frame is fixedly connected to the connecting rods. A fixing mechanism is provided inside the fixed frame, including a groove, balls, and pressing rods. The groove is located in the center of the inner side of the fixed frame, and several balls are evenly and movably engaged inside the groove. Pressing rods are movably inserted through the lower ends of both sides of the groove. This invention has good performance, facilitating the pressing and fixing of irregularly shaped materials. Its fixing effect is good, thus preventing the steel structure from shifting during welding and improving welding quality.

[0004] The above technical solution can facilitate the extrusion and fixation of irregularly shaped materials, thereby preventing the steel structure from shifting during welding and improving welding quality. Although it can achieve the effect of preventing shifting, relying solely on extrusion to fix the material during the welding process results in insufficient clamping positions, leading to poor material fixation and difficulty in adjusting the material's position. It requires repeated fixing of the material, which is quite inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a welding fixture with anti-deviation features to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding fixture with anti-deviation features, comprising a base plate, a mounting hole at the top of the base plate, a first column fixedly connected to the top of the base plate, a sliding groove at the top of the base plate, a lead screw rotatably connected through the inner wall of the sliding groove, a slider threadedly connected through the outer wall of the lead screw, a second column fixedly connected to the top of the slider, a throttle fixedly connected to the outer wall of the lead screw, and anti-deviation mechanisms provided on the outer walls of both the second column and the first column.

[0007] As a further preferred embodiment of this technical solution, a turntable is rotatably connected to the outer wall of both the second column and the first column. A fixed frame is fixedly connected to the outer wall of the turntable. A fixed tube is fixedly connected to the top of the fixed frame. A threaded rod is rotatably connected through the top of the fixed tube.

[0008] As a further preferred embodiment of this technical solution, a movable rod is slidably connected to the inner wall of the fixed tube, the threaded rod passes through and is threadedly connected to the inside of the movable rod, a clamping plate is fixedly connected to the bottom end of the movable rod, and a limit plate is slidably connected to the inner wall of the fixed frame.

[0009] As a further preferred embodiment of this technical solution, the limiting plate has a cavity inside, a spring is fixedly connected to the top of the cavity, an insert is fixedly connected to the bottom of the spring, and a movable groove is formed on the inner wall of the cavity.

[0010] As a further preferred embodiment of this technical solution, a connecting block is slidably connected to the inner wall of the movable groove, the outer wall of the connecting block is fixedly connected to the outer wall of the insert block, and a slot is provided at the bottom of the inner side of the fixed frame.

[0011] As a further preferred embodiment of this technical solution, the outer wall of the first column is provided with a flipping mechanism, the outer wall of the turntable is fixedly connected with a rotating shaft, the outer wall of the first column is provided with a positioning hole, and the inside of the rotating shaft is provided with a movable cavity.

[0013] This utility model provides a welding fixture with anti-deviation features, which has the following beneficial effects:

[0014] (1) This utility model rotates the handle, which drives the lead screw to rotate. The lead screw rotates and drives the slider to move inside the groove. At this time, the slider drives the second column to approach the first column, and then uses the clamping force on both sides to fix the material inside the fixed frame. The outer wall of the material is in contact with the inner wall of the fixed frame. Rotating the threaded rod drives the moving rod to move inside the fixed tube. The moving rod moves downward and drives the clamping plate to clamp and fix the material. Moving the connecting block upward, the connecting block drives the insert block to disengage from the slot. Moving the limiting plate inward, the limiting plate is tightly in contact with the outer wall of the material. Releasing the force on the connecting block, the squeezed spring drives the connecting block to reset, further fixing the material. While achieving the anti-deviation effect, it can clamp and fix multiple sides of the material.

[0015] (2) By moving the connecting arm outward, the connecting arm synchronously drives the positioning rod and the fixing rod to move outward. The positioning rod disengages from the inside of the positioning hole. The connecting arm rotates, and the connecting arm uses the movable plate to drive the rotating shaft to rotate, thereby driving the turntable to rotate. The fixed frame rotates, driving the entire material to rotate, which makes it easier for workers to weld the material. Attached Figure Description

The top of the fixed frame 92 is fixedly connected to a fixed tube 93. The top of the fixed tube 93 is rotatably connected to a threaded rod 94.

[0025] The threaded rod 94, when rotated, can drive the movable rod 95 to move vertically inside the fixed tube 93.

[0026] The inner wall of the fixed tube 93 is slidably connected to a movable rod 95, a threaded rod 94 passes through and is threadedly connected to the inside of the movable rod 95, a clamping plate 96 is fixedly connected to the bottom end of the movable rod 95, and a limit plate 97 is slidably connected to the inner wall of the fixed frame 92.

[0027] The fixed tube 93 can restrict the movement trajectory of the moving rod 95.

[0028] The limiting plate 97 has a cavity 98 inside, a spring 99 is fixedly connected to the top of the cavity 98, an insert block 910 is fixedly connected to the bottom of the spring 99, and a movable groove 911 is provided on the inner wall of the cavity 98.

[0029] Spring 99 can reset the plug 910 without the influence of external force.

[0030] The inner wall of the movable groove 911 is slidably connected to the connecting block 912, the outer wall of the connecting block 912 is fixedly connected to the outer wall of the insert block 910, and the bottom of the fixed frame 92 is provided with a slot 913.

[0031] The position of the limiting plate 97 can be limited by inserting the insert 910 into the slot 913.

[0032] The first column 3 has a flipping mechanism 10 on its outer wall, a rotating shaft 101 is fixedly connected to the outer wall of the turntable 91, a positioning hole 102 is opened on the outer wall of the first column 3, and a movable cavity 103 is opened inside the rotating shaft 101.

[0033] The flipping mechanism 10 can drive the turntable 91 to rotate, which can flip the material that needs to be welded.

[0036] This utility model provides a welding fixture with anti-deviation features, the specific working principle of which is as follows:

[0037] In use, the material to be welded is placed between the first column 3 and the second column 4. The handle 8 is rotated, causing the lead screw 6 to rotate. The lead screw 6 then moves the slider 7 inside the groove 5. At this time, the slider 7 moves the second column 4 closer to the first column 3, thus using the clamping force on both sides to fix the material inside the fixed frame 92. The outer wall of the material is in contact with the inner wall of the fixed frame 92. The threaded rod 94 is rotated, causing the moving rod 95 to move inside the fixed tube 93. The moving rod 95 moves downwards, causing the clamping plate 96 to clamp and fix the material. The connecting block 912 moves upwards, causing the insert block 910 to disengage from the slot 913. The limiting plate 97 moves inwards, making... The limiting plate 97 fits tightly against the outer wall of the material. When the force on the connecting block 912 is released, the compressed spring 99 drives the connecting block 912 to reset, further fixing the material and achieving the effect of preventing deviation. At the same time, it can clamp and fix multiple sides of the material. During the welding process, if it is necessary to flip the material, the connecting arm 106 is moved outward. The connecting arm 106 simultaneously drives the positioning rod 107 and the fixing rod 105 to move outward. The positioning rod 107 disengages from the interior of the positioning hole 102. The connecting arm 106 is rotated, and the connecting arm 106 drives the rotating shaft 101 to rotate through the movable plate 104, which in turn drives the turntable 91 to rotate. The fixed frame 92 rotates, causing the entire material to rotate, which makes it easier for the staff to weld the material.
