Description

Technical Field

[0001] This application relates to the field of riveting and welding technology, specifically to a multi-angle adjustable riveting and welding fixing device. Background Technology

[0002] In many fields such as machinery manufacturing, steel structure processing, and equipment assembly, riveting and welding are core processes for connecting and forming workpieces. As a key auxiliary component in riveting and welding operations, the performance of the fixing device affects the accuracy of workpiece positioning and the smoothness of the processing. In actual production scenarios, the workpiece needs to be kept in a stable position by the fixing device to ensure that the riveting points are aligned and the weld is uniform, thereby ensuring the structural strength and appearance quality of the final product.

[0003] A novel riveting and welding machine, application number CN201921796919.0, comprises a riveting and welding machine and a processing table, which are connected by a connecting rod fixed around their center. The length and width of the riveting and welding machine and the processing table are identical. The riveting and welding machine has a frame structure with multiple riveting and welding heads evenly arranged in the center. A motor is mounted on the frame of the riveting and welding machine. A servo motor is mounted on the side plate of the processing table, and the servo motor is connected to a cam mounted on the riveting and welding machine via a transmission shaft fixed to the connecting rod.

[0004] However, the riveting and welding fixing devices currently used in the market have certain limitations in terms of angle adjustment. Some workpieces require tilted riveting and welding due to design requirements. Existing devices often can only provide a single or limited fixed angle, making it difficult to flexibly adjust the positioning angle according to the specific processing surface of the workpiece. The aforementioned new type of riveting and welding machine has certain shortcomings. Its multiple riveting and welding heads are all fixedly set. This limitation forces operators to compensate for the deficiency by raising the workpiece or temporarily building auxiliary support structures. This not only increases the number of additional operating steps, but may also cause positional deviations of the workpiece during processing due to the instability of the temporary support, affecting the fit of the riveting and welding joint.

[0005] Therefore, it is necessary to provide a multi-angle adjustable riveting and welding fixing device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a multi-angle adjustable riveting and welding fixing device to achieve the effect of conveniently adjusting the riveting and welding angle requirements.

[0008] The technical solution adopted by this application to solve its technical problem is: a multi-angle adjustable riveting and welding fixing device, including a mounting frame, a second drive source connected to the inner side of the top of the mounting frame, a worm gear connected to the power output end of the second drive source, a support rod rotatably connected to the inner wall of one side of the mounting frame, a worm wheel connected to one end of the support rod, a linkage rod connected to one end of the worm wheel, an extension frame connected to one end of the linkage rod, a clamping assembly provided on the extension frame, and a first drive source connected to the inner wall of one side of the extension frame; The surface of the clamping assembly is poweredly connected to the power output end of the first driving source to drive the clamping assembly to perform opposing translational motion.

[0009] Furthermore, the clamping assembly includes a bidirectional lead screw and a slide rail. The bidirectional lead screw is disposed on the power output end of the first drive source. Two adjusting blocks are threadedly connected to the surface of the bidirectional lead screw through a lead screw nut. A reinforcing plate is connected to the bottom end of each of the two adjusting blocks. A high-elasticity silicone pad is connected to the inner side of each of the two reinforcing plates. The slide rail is disposed on the inner side of the top end of the extension frame. Four limiting blocks are slidably connected to the inner side of the bottom end of the slide rail.

[0010] Furthermore, one end of the bidirectional lead screw is rotatably connected to the inner wall of the other side of the mounting bracket via a bearing.

[0011] Furthermore, the two adjustment blocks are symmetrically arranged on the left and right sides of the vertical center line of the bidirectional lead screw.

[0012] Furthermore, the bottom end of each pair of limiting blocks is connected to the top end of each of the adjusting blocks.

[0013] Furthermore, the worm gear meshes with the worm, and the bottom end of the worm is rotatably connected to the inner side of the bottom end of the mounting bracket via a bearing.

[0014] Furthermore, the other side of the mounting bracket is slidably attached to one side of the extension bracket.

[0015] The beneficial effects of this application are as follows: The multi-angle adjustable riveting and welding fixing device provided by this application facilitates the opposing translational movement of the adjusting blocks via a bidirectional lead screw to achieve clamping operations on workpieces of different sizes and specifications. The symmetrical two adjusting blocks help to evenly distribute the clamping force on both sides of the workpiece, avoiding workpiece displacement or deformation caused by unilateral force. Simultaneously, the opposing movement adjustment method can flexibly adapt to workpieces of different sizes and specifications, eliminating the need for frequent replacement of clamping components and simplifying the operation process. The worm gear driving the worm wheel rotation facilitates multi-angle adjustment of the reinforcing plate and workpiece. The high-precision characteristics of the worm gear transmission ensure more accurate angle adjustment, meeting the needs of different processing angles. Furthermore, the worm gear structure has a self-locking effect, helping to maintain a stable state after angle adjustment, preventing angle displacement caused by external forces such as vibration and impact during riveting and welding, eliminating the need for an additional locking mechanism, and further improving the stability of the workpiece during the riveting and welding process.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figure 1-4 As shown, this application provides a multi-angle adjustable riveting and welding fixing device, including a mounting frame 1. A second drive source 5 is connected to the inner side of the top of the mounting frame 1. The power output end of the second drive source 5 is connected to a worm gear 6 to facilitate providing driving force to the worm gear 6. A support rod 7 is rotatably connected to the inner wall of one side of the mounting frame 1. One end of the support rod 7 is connected to a worm wheel 8, which is easily driven by the worm gear 6 to rotate stably. One end of the worm wheel 8 is connected to a linkage rod 9. One end of the linkage rod 9 is connected to an extension frame 4. A clamping assembly 2 is provided on the extension frame 4. A first drive source 3 is connected to the inner wall of one side of the extension frame 4. The surface of the clamping component 2 is poweredly connected to the power output end of the first driving source 3 to drive the clamping component 2 to perform opposing translational motion.

[0021] The clamping assembly 2 includes a bidirectional lead screw 21 and a slide rail 25. The bidirectional lead screw 21 is located on the power output end of the first drive source 3. Two adjusting blocks 22 are threadedly connected to the surface of the bidirectional lead screw 21 through a lead screw nut. The bottom ends of the two adjusting blocks 22 are connected to a reinforcing plate 23, which facilitates the two reinforcing plates 23 to move in opposite directions. The inner sides of the two reinforcing plates 23 are connected to a high-elasticity silicone pad 24. The friction of the high-elasticity silicone pad 24 helps to improve the stability of contact with the workpiece. The slide rail 25 is located on the inner side of the top of the extension frame 4. Four limiting blocks 26 are slidably connected to the inner side of the bottom end of the slide rail 25.

[0022] One end of the bidirectional lead screw 21 is rotatably connected to the inner wall of the other side of the mounting bracket 1 via a bearing, which helps to improve the stability of the rotation of the bidirectional lead screw 21.

[0023] The two adjusting blocks 22 are symmetrically arranged on the left and right sides of the vertical center line of the bidirectional lead screw 21, which makes it easier for the two adjusting blocks 22 to have symmetrical opposing translational forces, thereby improving the accuracy of the two adjusting blocks 22 when they move synchronously in opposite directions.

[0024] The bottom of each pair of limit blocks 26 is connected to the top of each adjustment block 22, which helps to improve the stability of the movement of the limit blocks 26 and the adjustment blocks 22.

[0025] The worm gear 8 meshes with the worm 6, facilitating transmission and rotation. The bottom end of the worm 6 is rotatably connected to the inner side of the bottom end of the mounting bracket 1 via a bearing, which improves the stability of the worm 6's rotation.

[0026] The other side of the mounting bracket 1 slides and fits into one side of the extension bracket 4, and the force of the fitting helps to improve the stability of the extension bracket 4 when it rotates to adjust the angle.

[0027] Working principle: First, the first drive source 3 is driven to operate according to the size of the workpiece. Assuming that a small workpiece is fixed at this time, the first drive source 3 drives the bidirectional lead screw 21 to rotate. Due to the shape characteristics of the bidirectional lead screw 21, the two adjusting blocks 22, the two reinforcing plates 23 and the two high-elasticity silicone pads 24 move in opposite directions in a synchronous approaching motion. Thus, the two reinforcing plates 23 clamp and fix the workpiece. The material characteristics of the high-elasticity silicone pads 24 help to increase the friction of the contact with the workpiece, thereby improving the stability of the workpiece clamping. Similarly, for clamping and fixing a larger workpiece, the two adjusting blocks 22 can be separated in opposite directions by driving the bidirectional lead screw 21 to rotate in the opposite direction. This is suitable for clamping and fixing larger workpieces. When the workpiece is fixed and the riveting angle needs to be adjusted, the second drive source 5 drives the worm gear 6 to rotate, which in turn drives the worm wheel 8 to rotate, thereby driving the linkage rod 9, the extension frame 4, and the two reinforcing plates 23 to perform multi-angle adjustments. The high-precision transmission characteristics of the worm gear 6 and worm wheel 8 make the angle adjustment of the workpiece more accurate, meeting the needs of different processing angles. Moreover, the transmission structure of the worm gear 6 and worm wheel 8 has a self-locking effect, which helps to maintain the stable state after the angle adjustment is completed, avoiding angle deviation caused by external forces such as vibration and impact during the riveting process. No additional locking mechanism is required, further improving the stability of the workpiece during the riveting process.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
