[0001] This utility model relates to the field of positioning tooling technology, specifically a positioning tooling for welding a walking aid frame. Background Technology
[0002] A walking aid is a medical device that assists in walking. Its frame is usually welded from multiple tubular components. During the welding process, the positioning and fixing of the various components of the frame are crucial to ensuring the welding quality. Traditional welding methods often rely on manual positioning and temporary fixing, which suffers from problems such as inaccurate positioning, low efficiency, and large welding deformation. Therefore, there is an urgent need for a dedicated positioning fixture to solve the above problems. However, this requires a high level of skill from the welder, limiting the scope of this job. To address this, a positioning fixture for welding walking aid frames is proposed. Utility Model Content

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] like Figure 1-4 As shown, a positioning fixture for welding a walking aid frame includes a base plate 1. Its features include a second base plate 2 inclinedly connected to the base plate 1, and several positioning modules disposed on the second base plate 2 for positioning walking aid frame components. Each positioning module includes a first locator 3 symmetrically disposed on the second base plate 2, a second locator 4 symmetrically disposed on the second base plate 2 and located above the first locator 3, a support column 5 symmetrically disposed on the second base plate 2 and located inside the second locator 4 and on the same horizontal line as the second locator 4 for supporting the corner connecting piece of the walking aid frame, and a support column 5 disposed on the second base plate 2 and located in the middle of the support column 5. The fixture 6 is used to fix the walking aid frame. By fixing the base plate 1 to the workbench and setting the base plate 2 at an angle on the base plate 1, it is easier for the operator to install the various parts of the walking aid frame onto the tooling. This is different from the traditional method of placing pipes vertically, which improves work efficiency and makes operation easier. By setting several positioning modules on the base plate 2, the positioning accuracy between the various parts of the walking aid frame is improved. It can also cooperate with robots to perform multi-point continuous welding, improve welding quality and work efficiency, reduce the skill level of the operator, and has a simple structure, which also reduces production costs.
[0020] In one embodiment, the locator 3 includes a positioning post 31 disposed on the base plate 2, a connecting piece 32 disposed on the positioning post 31, an adjusting screw 33 disposed at one end of the connecting piece 32 for laterally limiting the distance between the walker frame, and a threaded round tube 34 disposed at one end of the connecting piece 32 that is adapted to the adjusting screw 33. The tubes on both sides of the walker frame are provided with round holes. The operator aligns the round holes with the adjusting screw 33 on the locator 3 and inserts one end of the adjusting screw 33. Then, by rotating the adjusting screw 33, the distance between the tubes on both sides is adjusted, thus fixing the tubes and limiting the distance between the tubes on both sides of the walker frame.
[0021] In one embodiment, the second locator 4 includes a second locating post 41 disposed on the second base plate 2, a T-shaped connecting piece 42 disposed on the second locating post 41, a push-pull clamp 43 connected to the T-shaped connecting piece 42 and cooperating with the support post 5 to fix the corner connecting piece of the walker frame, and a limiting block 44 disposed tangentially to the second locating post 41 on the second locating post 41 for limiting both sides of the walker frame; the push-pull clamp 43 is provided with a conical post 431 adapted to the corner connecting piece of the walker frame and a spring 432 disposed on the conical post 431; the limiting block 44 is provided with a limiting screw 441 perpendicular to the limiting block 44; the support post 5 is provided with a positioning hole 5 adapted to support the corner connecting piece of the walker frame. 1. Place one end of the bend connecting piece of the walking aid frame on the positioning hole 51 of the support column 5, and fix the other end through the push-pull clamp 43 on the second locator 4. The conical column 431 on the push-pull clamp 43 is inserted into the round hole at the other end of the bend connecting piece of the walking aid frame. The push-pull clamp 43 is equipped with a spring 432, which can effectively buffer the downward pressure. The preload of the spring can compensate for the small deformation of the bend connecting piece or the gap caused by thermal expansion and contraction, ensuring clamping stability. At the same time, the limiting block 44 on the second locator 4 can limit the distance between the tubes on both sides of the walking aid frame by adjusting the limiting screw 441 on the limiting block 44. One end of the limiting screw 441 contacts the tube and limits the distance between the tubes on both sides.
[0022] In one embodiment, the fixture 6 includes a positioning post 61 disposed on the base plate 2, a support rod 62 connected to the top of the positioning post 61 for lateral support of the walker frame, a flip-type clamp 63 fixed to the support rod 62 for fixing the walker frame, and a limiting connecting piece 64 disposed at both ends of the support rod 62 for limiting the placement position of the walker frame corner connecting piece on the support post 5.
[0023] Place the transverse tubes of the walker frame on the support rod 62 on the fixing device 6, and use the flip-type clamp 63 to fix the transverse tubes on the support rod 62 to prevent the tubes from loosening or falling and affecting the welding. The limiting connecting pieces 64 on both sides can straighten the corner connecting pieces of the walker frame to avoid position correction and affect the installation of the walker frame and other accessories.
[0024] In one embodiment, a plurality of diagonal braces 7 are provided at the connection between the base plate 1 and the base plate 2.
[0025] When using this utility model, firstly, place the horizontal tube of the walker frame on the support rod 62 on the fixing device 6, and fix the tube on the support rod 62 with the flip-type clamp 63. Then, place the corner connecting piece of the walker frame in the positioning hole 51 of the support column 5. The corner connecting piece of the walker frame is aligned by the limiting connecting piece 64 on the support rod 62. Then, insert the tubes on both sides of the walker frame into one end of the adjusting screw 33 on the locator 3 through the round hole provided on the tube. The distance between the tubes on both sides is positioned by adjusting the adjusting screw 33. The distance between the other ends of the tubes on both sides is positioned by adjusting the limiting screw 441 on the limiting block 44, so that one end of the limiting screw 441 presses against the tube for positioning.
