[0002] When welding automotive parts, a clamping device is needed to clamp the workpiece and inspect the workpiece quality. In order to facilitate the inspection and processing of parts on the clamp, the staff needs to move to the designated position to work, and the clamp also needs to have good stability during the work process to avoid affecting work efficiency.

[0003] The XY workbench with patent application number CN204221751U includes: a first base, a second base and an operating table. Two guide rails are arranged on the first base, and each guide rail is provided with a slider; the bearing part and the driving part are fixed between the two guide rails at intervals, and the screw with a screw nut is connected to the bearing part and the driving part; the second base is fixed to the two sliders and the screw nut.

In order to realize the movement of parts in the X-axis and Y-axis directions, the above-mentioned device needs to be driven by a motor, which makes the device as a whole complicated, bulky and inconvenient to move. Therefore, it is urgent for those skilled in the art to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an XY axis positioning device for a welding assembly fixture in view of the deficiencies of the above-mentioned prior art. The XY axis positioning device for the welding assembly fixture is configured to install the welding assembly fixture on a carrying platform, and then drive the welding assembly fixture on the carrying platform to move on the X axis plane and the Y axis plane by operating the X axis operating panel and the Y axis operating panel, so as to facilitate the operation of the staff.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] An XY axis positioning device for a welding assembly fixture comprises a base plate, an X-axis guide rail, a Y-axis guide rail, a positioning block, an X-axis operating disk, a Y-axis operating disk and a bearing platform, wherein the X-axis guide rail is arranged on the base plate, the X-axis guide rail head end is arranged with the X-axis operating disk, the Y-axis guide rail head end is arranged with the Y-axis operating disk, the positioning block is arranged between the X-axis guide rail and the Y-axis guide rail, and the bearing platform is arranged on the Y-axis guide rail.

[0007] Furthermore, the X-axis guide rail and the Y-axis guide rail each include a transmission screw, two support rods and a limit piece, the limit piece is provided with a screw hole, and the transmission screw and the support rod are sequentially arranged between the two limit pieces.

[0008] The design of 1 transmission screw and 2 support rods can provide stable linear transmission, make positioning more accurate, effectively prevent shaking and deviation during work, and ensure that the welding assembly fixture moves accurately and smoothly in the XY axis direction. Multiple screws work together to disperse the load, enhance the rigidity and stability of the overall structure, and maintain a good operating state even under heavy loads, prevent deformation and wear, and extend the service life of the equipment. The existence of the limiter can provide a clear boundary for the movement range of the transmission screw, and achieve precise limiting through the screw hole and the screw rod to avoid mechanical collision or damage caused by exceeding the stroke, ensuring safe and reliable operation of the equipment. Fine-tuning can be easily performed by rotating the screw rod to meet the positioning requirements of welding assemblies of different specifications, thereby improving the adaptability and flexibility of the equipment.

[0009] Furthermore, the transmission screw located at the middle position of the limiting member is connected to the X-axis operating disk or the Y-axis operating disk.

[0010] The transmission screw in the middle position is directly connected to the operating panel, which can directly convert the operator's rotational action into linear motion along the axial direction, realize precise control of the welding assembly fixture, and the operation is intuitive and easy. Since the transmission screw and the support rod are evenly distributed between the limiters, the middle screw serves as the main drive, which helps to maintain the mechanical balance of the overall structure, avoid the problem of eccentric load caused by excessive force on one side, and ensure the smooth and safe operation of the equipment. The middle transmission screw is directly controlled by the operating panel, which reduces the links of the transmission chain, can respond to operating instructions faster, and improve the speed and accuracy of positioning. This design has a compact structure and is easy to maintain. It also reduces manufacturing costs and failure rates, and improves the overall performance and reliability of the equipment.

[0011] Furthermore, the X-axis operating disk or the Y-axis operating disk includes an operating handle and an operating wheel, the operating wheel is connected to the operating handle, and the operating handle is provided with an anti-slip sleeve.

[0012] The operating wheel design makes it easy for staff to accurately adjust the moving distance of the X-axis or Y-axis by rotating it. Compared with simple handle operation, it is more labor-saving and accurate, especially when fine adjustment is required, it can achieve a continuous and smooth operation experience. The anti-slip cover set on the operating handle can increase the friction of the grip to prevent hand slippage due to sweating or other reasons, ensure that the handle can be firmly held during operation, prevent misoperation, and further improve the safety and stability of the operation. The anti-slip cover can also act as a buffer, reduce the fatigue of the hand caused by holding the handle for a long time, and improve the comfort of operation.

[0013] The positioning block is provided with three corresponding X-axis limiting holes in the X-axis direction, and the X-axis guide rail passes through the X-axis limiting holes; three corresponding Y-axis limiting holes are arranged above the X-axis limiting holes in the Y-axis direction, and the Y-axis guide rail passes through the Y-axis limiting holes.

[0014] The X-axis and Y-axis are fixed by their own limit holes, which can ensure that the guide rail is strictly positioned in two-dimensional space and prevent loosening and deviation in any direction, greatly improving the positioning accuracy of the welding assembly fixture in the XY axis direction. The design of three limit holes increases the contact points for the guide rail to be fixed, enhances the stability of the overall structure, and reduces the risk of deformation caused by uneven force. The multi-point limit design facilitates fast and accurate assembly and adjustment according to actual needs. Whether it is the initial installation or later maintenance, it can quickly find the position and lock it, improving the practicality of the equipment.

[0015] Furthermore, the bearing platform is arranged between the Y-axis guide rails, the upper end of the limit member of the Y-axis guide rail is provided with a bearing surface and positioning teeth, the bearing platform is arranged on the bearing surface, the positioning teeth are provided with screw holes to fix the bearing platform, and the bearing platform is provided with multiple positioning screw holes.

[0016] The bearing platform is arranged between the Y-axis guide rails. The good supporting effect of the guide rails is utilized to ensure that the bearing platform can stably bear the welding assembly fixture and the parts to be inspected in the Y-axis direction, avoiding the influence caused by the unstable bearing. The combination of the positioning teeth and the screw holes on the bearing surface enables the bearing platform to be accurately docked and tightened during installation, avoiding looseness or position displacement during operation, thereby ensuring the accurate placement of the inspected workpiece. The multiple positioning screw holes arranged on the bearing platform can select the appropriate fixed position according to the size and shape of different welding assemblies, realize flexible fixture replacement and positioning adjustment, and improve the versatility and adaptability of the equipment. The screw hole fixing method not only ensures the connection strength between the bearing platform and the Y-axis guide rail, but also facilitates the daily inspection, maintenance and disassembly and assembly of the equipment, thereby improving the safety and reliability of the equipment.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model is set through the design of X-axis guide rail and Y-axis guide rail, which can realize precise adjustment and movement in a two-dimensional plane, ensure the precise positioning of the welding assembly fixture in the horizontal direction, thereby improving the accuracy of the assembly position of the welded parts. The X-axis operation panel and the Y-axis operation panel respectively control the movement of their respective axial directions, so that the operator can flexibly adjust the position of the welding assembly according to actual needs, adapt to different workpiece sizes and shapes, and improve production efficiency and equipment applicability;

[0019] 2. Multiple positioning screw holes are set on the bearing platform, and suitable fixing positions can be selected according to the size and shape of different welding assemblies, so as to realize flexible fixture replacement and positioning adjustment, thereby improving the versatility and adaptability of the equipment. The overall device is simple and light in weight, and the device can be fixed in the designated working area by moving the entire device and fixing it through the base.
