Description
Technical Field
[0001] This utility model relates to the field of riveting and welding processing technology, and in particular to a riveting and welding processing positioning structure. Background Technology
[0002] Riveting is a type of electric welding. The typical method involves penetrating the surfaces to be welded with a welding rod, and it is generally used for welding relatively thick metals. Riveting is particularly suitable for joining parts made of different materials.
[0003] However, the existing positioning structure is fixed and can only clamp a single workpiece. When other workpieces need to be clamped, other positioning structures must be replaced, which is costly and inconvenient. At the same time, since the welding angle between different workpieces is not fixed, workers need to hold the workpieces to adjust the angle between the two workpieces in order to facilitate welding. However, the workpiece temperature is very high during welding, which poses a risk of burns.
[0004] Therefore, those skilled in the art have provided a riveting and welding positioning structure to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a riveting and welding positioning structure. The adjustable clamping mechanism allows for adjustment of the clamping frame position according to the required workpiece length, enabling clamping of workpieces of different lengths. Furthermore, the angle adjustment mechanism allows for adjustment of the angle of the working plate, thus enabling processing of workpieces of different shapes and welding positions, resulting in better usability.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A riveting and welding positioning structure includes a base plate, with connecting columns fixedly connected to both sides of the upper end face of the base plate, a fixing frame fixedly connected to the upper end of the two connecting columns, and a working plate rotatably connected to both sides of the fixing frame. An adjustable clamping mechanism is provided on both working plates, and an angle adjustment mechanism is provided between the two working plates and the base plate.
[0008] The adjustable clamping mechanism includes two fixed plates, which are respectively fixedly connected to the front and rear sides of the upper end face of the working plate. A limit rod is fixedly connected between the two fixed plates. Movable sleeve plates are movably sleeved on both sides of the outer wall of the limit rod. A clamping frame and a limiting post are fixedly connected to both sides of the movable sleeve plate. A moving hole is opened on one side of the limiting post. A reset groove is opened on the inner wall of the front and rear ends of the moving hole. A fixed rod is fixedly connected between the inner walls of both sides of the reset groove. A reset spring and a movable sleeve are movably sleeved on both sides of the outer wall of the fixed rod. A moving rod is fixedly connected between the two movable sleeves. A plurality of engaging grooves are opened on one side of the working plate. One end of the moving rod is engaged in the engaging groove.
[0009] With the above technical solution, when clamping the workpiece, the distance between the two clamping frames on the same side can be adjusted according to the length of the workpiece. The moving rod moves and drives the moving sleeve column to move. The return spring is compressed and the moving rod separates from the locking groove. After pushing the limiting column to the required position, the return spring pops out and pushes the moving sleeve column to move. The moving rod moves synchronously under force and locks in the locking groove. The position of the limiting column is fixed, and the two ends of the workpiece are respectively clamped in the two clamping frames.
[0010] Furthermore, the angle adjustment mechanism includes two fixed slots and multiple threaded slots. The two fixed slots are respectively opened on one side of the upper end face of the base plate near the front and back. Threaded rods are rotatably connected between the inner walls of the two fixed slots. Sliding seats are threadedly fitted on the outer walls of the two threaded rods. Lower rotating seats are fixedly connected to the upper end faces of the two sliding seats. Connecting chain rods are rotatably connected inside the two lower rotating seats. Upper rotating seats are fixedly connected to one side of the lower end face of the working plate near the front and back. The upper end of the connecting chain rod is rotatably connected inside the upper rotating seat.
[0011] Through the above technical solution, the rotation of the threaded rod drives the sliding seat to move, the lower rotating seat moves synchronously under the force and pushes the upper rotating seat to move under the action of the connecting chain rod. At this time, the angle of the working plate can be adjusted, which can clamp workpieces of different shapes and adjust the exposed position of riveting and welding at different angles.
[0012] Furthermore, multiple threaded grooves are respectively opened on the front and rear sides of one side outer wall of the base plate. One end of the threaded rod is fixedly connected to a fixing plate. The fixing plate has a threaded hole, and a fixing bolt is threaded in the threaded hole. One end of the fixing bolt is threaded in the threaded groove.
[0013] By using the above technical solution, the threads of the fixing bolts are fitted into the threaded holes and grooves by twisting the fixing bolts, and the fixed position of the fixing plate is fixed, which can avoid the problem of structural instability caused by the rotation of the threaded rod.
[0014] Furthermore, a limiting slider is fixedly connected to the lower end face of the sliding seat, and a limiting groove is formed on the lower inner wall of the fixing groove, and the limiting slider is slidably disposed in the limiting groove.
[0015] The above technical solution achieves the purpose of limiting the movement of the sliding seat by sliding the limiting slider in the limiting groove.
[0016] Furthermore, a telescopic rod is fixedly connected to the upper end of the clamping frame, a clamping plate is fixedly connected to the output end of the telescopic rod, and an anti-slip pad is fixedly connected to the inner wall of the lower end of the clamping frame.
[0017] The above technical solution enables the workpiece to be stably clamped by the working of the telescopic rod and the clamping plate, thus allowing for workpiece clamping and processing.
[0018] Furthermore, the two ends of the reset spring are respectively fixedly connected to the inner wall of the movable sleeve and the reset groove on one side, and the reset spring is made of carbon steel.
[0019] By using the above technical solution and limiting the position and material of the return spring, the goal of high-strength use can be achieved.
[0020] Furthermore, the limiting post is fitted to the working plate, and a pull head is fixedly connected to one end of the moving rod;
[0021] The above technical solution achieves better sliding by limiting the fit between the column and the work plate, and the pull head allows for control of the movement of the moving rod.
[0022] This utility model has the following beneficial effects:
[0023] 1. The riveting and welding positioning structure proposed in this utility model allows for the adjustment of the distance between two clamping frames on the same side when clamping a workpiece, based on the workpiece length. Pulling the pull head moves the moving rod and drives the moving sleeve column to move. The return spring is compressed, and the moving rod separates from the engagement groove. After pushing the limiting column to the desired position, the pull head is released, the return spring pops out, and then pushes the moving sleeve column to move. The moving rod moves synchronously under force and engages in the engagement groove. The position of the limiting column is fixed. The two ends of the workpiece are respectively fitted into the two clamping frames. The telescopic rod works to drive the clamping plate to stably clamp the workpiece, thus enabling the clamping and processing of workpieces of different lengths, and providing better practicality.
[0024] 2. The riveting and welding positioning structure proposed in this utility model involves twisting the fixed plate, causing the threaded rod to rotate and thus moving the sliding seat. The lower rotating seat moves synchronously under the force and pushes the upper rotating seat to move under the action of the connecting chain. At this time, the angle of the working plate can be adjusted, allowing for clamping of workpieces of different shapes and adjustment of the exposed riveting and welding position at different angles, thus improving usability. After adjustment, the fixed bolt is twisted to make its thread fit into the threaded hole and threaded groove. The fixed plate position is fixed, which avoids the problem of structural instability caused by the rotation of the threaded rod, thus improving usability.
[0025] 3. The riveting and welding processing positioning structure proposed in this utility model can adjust the position of the clamping frame according to the required length of the workpiece through the adjustable clamping mechanism, so as to clamp workpieces of different lengths. Furthermore, the angle adjustment mechanism can adjust the angle of the working plate, thereby enabling the processing and use of workpieces of different shapes and welding positions, thus having better usability.
