Description

Technical Field

[0001] The utility model relates to the technical field of metal workpiece processing equipment, in particular to an adjustable limiting mechanism for metal workpiece processing. Background Art

[0002] In the metalworking industry, position limiters are an essential piece of equipment. They are primarily used to stabilize and precisely position the workpiece during machining, ensuring smooth processing and ensuring the quality of the final product. With the rapid development of modern manufacturing, higher requirements are being placed on the machining accuracy and efficiency of metal workpieces.

[0003] However, in the current field of metal processing, traditional limit mechanisms often have many limitations. On the one hand, most of them adopt a fixed or single adjustment method, which makes it difficult to adapt to the processing requirements of workpieces of different sizes and shapes, resulting in cumbersome and inefficient processing procedures. On the other hand, for workpieces that need to be rotated, traditional limit mechanisms often lack effective rotation support, requiring frequent manual flipping and repositioning of the workpiece, which not only increases the labor intensity of the operator, but also easily introduces processing errors, causing the practicality of the limit mechanism to decrease. Therefore, we propose an adjustable limit mechanism for metal workpiece processing to solve the above problems. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Reference Figure 1-5An adjustable limit mechanism for processing metal workpieces includes a mounting plate 1, which is U-shaped. Two support plates 5 are symmetrically arranged on the inner side of the mounting plate 1. Two clamping plates 8 are symmetrically arranged between the two support plates 5. A clamping plate 2 9 is provided on one side of each clamping plate 8. The clamping plates 1 8 and the clamping plates 2 9 are connected by an adjustment assembly, wherein two adjustment assemblies are provided, and the two adjustment assemblies are respectively located on both sides of the clamping plates 2 9. A rotating assembly connected to the two clamping plates 1 8 is provided between the two support plates 5. A clamping assembly connected to the two support plates 5 is provided inside the mounting plate 1. Two support legs are symmetrically fixedly connected to both sides of the bottom of the mounting plate 1. Specifically, when the workpiece needs to be processed, the operator will adjust the adjustment assembly according to the specific size of the workpiece. By rotating the bolt 11, the nut 12 moves along the limit rod, thereby driving the clamping plate 2 9 to move horizontally relative to the clamping plate 1 8 until the spacing between the two clamping plates, i.e., the clamping plates 1 8 and the clamping plates 2 9, just fits the width of the workpiece. At this point, the provision of anti-slip grooves ensures that the workpiece is not easily slipped during the clamping process, improving clamping stability. If the workpiece requires rotational processing, the operator activates Motor 2 (6) in the rotating assembly. The rotational power of Motor 2 (6) is transmitted to the rotating rod (7) via a transmission device, which then drives the connected clamping plate (8) and the clamped workpiece to rotate. This rotational motion can be adjusted at multiple angles and positions according to processing requirements to meet complex processing requirements. At the same time, to achieve adaptive clamping of the workpiece length, Motor 1 (2) in the clamping assembly is activated. Motor 1 (2) drives the bidirectional screw (3) to rotate, causing the two screw sleeves (4) to move relative to each other along the screw. This drives the support plate (5) and the connected clamping plates (8) and (9) to move laterally, thereby achieving precise clamping of the workpiece length. Through the precise design of the adjustment assembly and clamping assembly, the limit mechanism can achieve precise clamping of the workpiece width and length. This precise clamping helps reduce errors and deviations during the processing process, improves the processing accuracy and surface quality of the workpiece, reduces labor intensity through the rotating assembly, and shortens processing preparation time. Greatly improve work efficiency and processing speed.

[0025] Furthermore, the clamping assembly includes a motor 2 arranged on one side of the mounting plate 1, and the bottom of the motor 2 is fixedly connected to the outer side wall of the adjacent end of the mounting plate 1 through a bracket, and the output end of the motor 2 is transmission-connected with a bidirectional screw rod 3, and the end of the bidirectional screw rod 3 is rotatably connected to the inner side wall of the adjacent end of the mounting plate 1, and both ends of the outside of the bidirectional screw rod 3 are sleeved with screw sleeves 4, and one side of the outer ring of the two screw sleeves 4 is fixedly connected to the adjacent end of the adjacent support plate 5. Specifically, through the setting of the screw sleeve 4, the bidirectional screw rod 3 is driven to rotate by starting the motor 2, and the two screw sleeves 4 are horizontally displaced closer to each other, and the screw sleeve 4 drives the support plate 5 on the outer side to move. At this time, the clamping plate 18 is driven by the rotating rod 7 and the clamping plate 2 9 is driven to move together through the bolts 11, the fixing plate 10, etc., so that the two clamping plates 1 8 and the two clamping plates 2 9 are close to each other to clamp and position the two sides of the outside of the workpiece, and can adapt to workpieces of different lengths to a certain extent.

[0026] Furthermore, a guide rod is embedded inside the two screw sleeves 4 and below the bidirectional screw rod 3, and both ends of the guide rod are fixedly connected to the inner side walls of the mounting plate 1 at both ends. Specifically, through the setting of the guide rod, the guide rod can limit the screw sleeve 4 to prevent the screw sleeve 4 from rotating along with the bidirectional screw rod 3.

[0027] Furthermore, the rotating assembly includes a motor 2 6 arranged on one side of one of the support plates 5, and one side of the motor 2 6 is fixedly connected to the adjacent side wall of the adjacent support plate 5 through a support frame, and the outer walls of the two clamping plates 8 on the side away from each other are fixedly connected to a rotating rod 7, one end of the rotating rod 7 away from the clamping plate 8 passes through the side wall of the adjacent support plate 5 and is transmission-connected to the output end of the motor 2 6, and the other end of the rotating rod 7 away from the clamping plate 8 is rotationally connected to the adjacent side wall of the adjacent support plate 5. Specifically, through the setting of the rotating rod 7, by starting the motor 2 6 to drive one of the rotating rods 7 to rotate, the adjacent clamping plate 8 is then driven to rotate. At this time, the workpiece in the clamp is rotated to process other parts of the metal workpiece through the cooperation of the other clamping plate 8 and the other rotating rod 7, thereby eliminating the need for personnel to release the positioning of the workpiece, flip it over and re-position it, thereby reducing personnel operation and improving the adjustability and practicality of the limit mechanism.

[0028] The nut 12 is then driven by the fixing block 11 to move the fixing block 11 so that the fixing block 11 can move along the fixing block 11, thereby adjusting the distance between the fixing block 11 and the fixing block 11. The fixing block 11 is fixedly connected to the fixing block 11 on the outer side of the fixing block 11, and the fixing block is fixedly connected to the adjacent outer side wall of the fixing block 11 away from the nut 12. The fixing block 10 is fixedly connected to the limiting rod on the side close to the bolt 11, and the limiting rod extends through the mounting block away from the fixing plate 10 to the outside of one side of the mounting block. Specifically, through the setting of the bolt 11, a person can hold one end of the bolt 11 and screw it to make the nut 12 move along the limiting rod, and then the nut 12 drives the clamping plate 2 9 to move and adjust the distance between the clamping plate 1 8 and the clamping plate 2 9. By adjusting the spacing between the clamping plate 1 8 and the clamping plate 2 9, it can meet the adaptability of workpieces of different widths, thereby further improving the applicability of the limiting mechanism.

[0029] Furthermore, the inner walls of one side of the two clamping plates 8 and the two clamping plates 2 9 are provided with anti-slip grooves. Specifically, through the setting of the anti-slip grooves, the presence of the anti-slip grooves not only enhances the friction between the multiple clamping plates and the workpiece, but also significantly improves the stability and reliability of clamping.

[0030] In summary:

[0031] When the operator needs to adjust the distance between clamping plate 1 (8) and clamping plate 2 (9) to accommodate workpieces of varying widths, they grasp one end of bolt 11 and rotate it. This drives nut 12 along the axial direction of bolt 11. The outer portion of nut 12 is fixedly connected to a mounting block, which is securely attached to the outer wall of clamping plate 2 (9). Therefore, as nut 12 moves along bolt 11, it drives clamping plate 2 (9) along with it via the mounting block. This movement is smooth and controllable, ensuring that clamping plate 2 (9) can be accurately adjusted to the desired position.

[0032] To restrict the movement of nut 12 and prevent it from falling out during rotation, a limit rod is fixedly attached to the side of the fixing plate 10 near the bolt 11. This limit rod extends through the mounting block and onto its exterior, providing a stable guide path for nut 12. As nut 12 moves, it slides along the limit rod, ensuring linear and stable movement. Adjustable components allow the limit mechanism to easily adapt to workpieces of varying widths without having to replace or adjust the entire fixture structure, greatly improving the flexibility and adaptability of the device. When motor 1 (2) is activated, its rotational power is directly transmitted to the bidirectional lead screw 3, driving its rotational motion. This causes the two screw sleeves 4 to move relative to each other along the lead screw surface. This in turn drives the support plate 5 and its connected clamping plates 1 (8) and 2 (9) to move laterally. This movement is synchronized and coordinated, ensuring that clamping plates 1 (8) and 2 (9) approach each other along a predetermined trajectory. During the workpiece clamping process, the operator first adjusts the position of the screw sleeve 4 according to the workpiece length to ensure that clamping plates 1 (8) and 2 (9) are in the appropriate initial position. Then, starting Motor 1 (2) rotates the bidirectional screw (3), driving the screw sleeve (4) and support plate (5) toward the workpiece. As clamping plates (1) (8) and (2) (9) gradually approach, they fit snugly against the workpiece's exterior, effectively clamping and positioning it. The clamping force is uniform and stable, easily adapting to workpieces of varying lengths. This allows for precise clamping of workpieces of varying sizes, enhancing the versatility and flexibility of the limiter mechanism.

[0033] When the motor 2 6 is started, its output end begins to rotate, driving one of the rotating rods 7 to rotate accordingly, and the clamping plate 1 8 fixedly connected at its end also performs circular motion around its axis. This movement is converted into the rotation of the workpiece itself through the close contact between the clamping plate 1 8 and the workpiece. At this time, the clamping plate 1 8 on the other side serves as a support and fixed point, and the free rotation of the other rotating rod 7 connected to it on the support plate 5 ensures the stability and balance of the workpiece during the rotation process, avoiding vibration or deviation caused by uneven force on one side. During the rotation process, the workpiece can be processed at multiple angles and positions in conjunction with other processing equipment, so that the workpiece does not need to be frequently manually flipped and repositioned, which greatly shortens the processing cycle, improves production efficiency, and reduces labor intensity.
