Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of gasket welding, and in particular relates to an automatic welding machine for piston gaskets. Background Art
[0002] Piston gaskets are critical components used to adjust the travel of hydraulic pistons in engines and are typically made of metal or composite materials. Piston gasket production requires welding, which requires positioning to ensure weld stability. However, existing piston gasket welding machines are not suitable for positioning workpieces of varying lengths, resulting in significant limitations and a limited scope of application.
[0003] Patent publication number CN220761485U discloses a cylinder gasket welding jig comprising a housing, cylinder gasket, workbench, pressure plate, adjusting bolts, guide grooves, a rotating drum, and a synchronizing plate. To use the jig, a worker places the cylinder gasket on the workbench until one side of the gasket is restrained by a stop plate. The adjusting bolt is then rotated to move the synchronizing plate downward, which in turn moves the rotating drum downward. Guided by the guide grooves, the rotating drum rotates as it moves downward, causing the pressure plate to rotate above the sealing disc, thereby positioning the cylinder gasket.
[0004] However, the distance between the two synchronizing plates in the above solution is fixed, and the limit plates installed on the top of the workbench alone cannot limit the position of cylinder gaskets of different lengths. If the cylinder gasket is too short, the pressure plate cannot compress and limit the ends of the cylinder gasket, making it impossible to effectively position the cylinder gasket. Therefore, the above solution has significant limitations in cylinder gasket positioning and cannot position cylinder gaskets of different lengths. It has a limited scope of application and poor actual performance. Utility Model Content

[0021] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, and those skilled in the art should know that the embodiments described below are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0022] As shown in Figures 1-4 The technical scheme adopted by the present application is as follows: a piston gasket automatic welding machine, comprising a main body 1 and a workpiece 3, the main body 1 is assembled with a welding mechanism 4 and is fixedly connected with a mounting seat 2 through bolts, the welding mechanism 4 is located above the mounting seat 2, and the mounting seat 2 is provided with a positioning mechanism for limiting the workpiece 3.
[0023] The positioning mechanism comprises a sliding plate 7, a cavity is formed in the mounting seat 2, two sliding plates 7 are arranged in the cavity and are limited to slide in the horizontal direction, and the mounting seat 2 is provided with a driving member for driving the two sliding plates 7 to slide towards or away from each other. Two sliding grooves 5 are symmetrically formed in the top of the mounting seat 2, and the two sliding grooves 5 are in communication with the cavity. One sliding block 11 is fixedly arranged at each end of each sliding plate 7, and the two sliding blocks 11 on the same sliding plate 7 are in one-to-one corresponding limited sliding cooperation with the two sliding grooves 5. One clamping plate 6 is rotatably arranged between the two sliding blocks 11 on the same sliding plate 7, and the two clamping plates 6 are arranged towards each other. In addition, torsional springs 10 are arranged between the two ends of the clamping plate 6 and the connected sliding blocks 11, one end of the torsional spring 10 is fixedly connected with the clamping plate 6, and the other end is fixedly connected with the sliding block 11.
[0024] In addition, each clamping plate 6 is composed of two mutually perpendicular sub-plates, and a limiting block is arranged on each sliding block 11, the limiting block is in abutting cooperation with one sub-plate of the clamping plate 6, and the limiting block is used for limiting the clamping plate 6, so that one sub-plate of the clamping plate 6 is in a vertical state when clamping the workpiece 3.
[0025] The driving member comprises a motor 9, the motor 9 is fixedly installed in the cavity, and a bidirectional screw rod 8 is rotatably arranged in the horizontal direction. The output shaft of the motor 9 is fixedly connected with one end of the bidirectional screw rod 8 in a same axis, and the other end of the bidirectional screw rod 8 is rotatably connected with the inner wall of the cavity of the mounting seat 2. The two threaded segments of the bidirectional screw rod 8 correspond to the two sliding plates 7, and each sliding plate 7 is in threaded cooperation with the corresponding threaded segment.
[0026] It should be noted that the state of the clamping plate 6 not clamping the workpiece 3 is as shown in Figure 4 , which is also the initial state before clamping.
[0027] Working principle: when in use, the workpiece 3 is placed on the top of the mounting seat 2, and is located in the middle position of the two sliding plates 7. The motor 9 is started, the output shaft of the motor 9 drives the bidirectional screw rod 8 to rotate, the bidirectional screw rod 8 drives the two sliding plates 7 to move close to each other along the central axis of the bidirectional screw rod 8, so as to drive the two clamping plates 6 to move close to each other through the sliding block 11.
[0028] The two clamping plates 6 will contact the workpiece 3 in the process of moving close to each other, and after contacting the workpiece 3, the clamping plate 6 will rotate. Under the action of the limiting block, one part of the clamping plate 6 presents a vertical state, and the other part presents a horizontal state, and the torsional spring 10 will generate a torsional force. The horizontal state plate will limit the top of the workpiece 3, and the vertical state plate will clamp and limit the workpiece 3, thereby improving the limiting effect.
[0029] When it is necessary to release the limiting of the workpiece 3, the output shaft of the control motor 9 is reversely rotated, the output shaft of the motor 9 drives the two clamping plates 6 to move away from each other, thereby releasing the limiting of the workpiece 3. At the same time, the two clamping plates 6 will reset under the elastic action of the torsional spring 10.
