Description

Technical Field

[0001] This utility model relates to the technical field of punching and shearing machine devices, specifically a workpiece positioning structure for a punching and shearing machine with multi-angle adjustment. Background Technology

[0002] In the field of punching and shearing machining, workpiece positioning accuracy and adjustment efficiency directly affect processing quality and production efficiency. Traditional punching and shearing machine workpiece positioning structures generally suffer from the following technical bottlenecks: most positioning devices only support linear movement in the horizontal direction, making it difficult to flexibly adjust the workpiece angle. This necessitates manual disassembly and reassembly of the workpiece to change the processing orientation, leading to the accumulation of clamping errors, especially significant in the processing of complex-shaped workpieces, resulting in substantial accuracy loss. Some equipment uses a purely manual adjustment structure, which is prone to displacement or wobbling of the positioning components due to human error during adjustment. Furthermore, the lack of a rigid guiding structure makes the workpiece susceptible to displacement under the impact of punching and shearing forces, affecting processing consistency. Utility Model Content

[0003] The purpose of this invention is to provide a workpiece positioning structure for punching and shearing machines that can be adjusted at multiple angles, which can solve the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle adjustable workpiece positioning structure for a punching and shearing machine, comprising a positioning table, positioning components, and positioning clamps. The top of the positioning table is provided with two positioning components, and the bottom of the two positioning components is respectively provided with a rotating base and a movable base. The top of the positioning components is provided with a positioning clamp, and the top surface of the positioning table is provided with a movable track, with the rotating base slidably disposed inside the movable track.

[0005] Specifically, a threaded rod and a first guide rod are provided between the rotating base and the movable base. One end of the first guide rod is fixedly connected to the side of the rotating base, and the other end of the first guide rod passes through the movable base and is slidably connected to the movable base. One end of the threaded rod is rotatably connected to the side of the rotating base, and the other end of the threaded rod passes through the movable base and is threadedly connected to the movable base.

[0006] Specifically, a track slide is provided in the middle of the bottom surface of the rotating base. The top of the track slide is connected to the rotating base through a rotary bearing. The rotating base is slidably set in the moving track through the track slide. A handle is provided on one side of the rotating base. The handle passes through the rotating base and is connected to one end of the threaded rod.

[0007] Specifically, the bottom surface of the movable base is provided with rollers.

[0008] Specifically, the positioning component is provided with an outer shell, and a bidirectional lead screw and a second guide rod are provided inside the outer shell. The two ends of the second guide rod are fixedly connected to the inside of the outer shell, and the two ends of the bidirectional lead screw are rotatably connected to the inside of the outer shell. The outer shell is provided with two moving blocks, each of which has two through holes. The moving block is slidably connected to the second guide rod through one through hole, and the moving block is threadedly connected to the bidirectional lead screw through the other through hole.

[0009] Specifically, a motor is provided on one side of the outer casing, and the output shaft of the motor is connected to one end of a bidirectional lead screw.

[0010] Specifically, the top of the movable block is provided with a connecting rod, and a sliding groove is opened on the top surface of the outer shell. The connecting rod passes through the sliding groove. Two mounting seats are provided on the top surface of the outer shell. The bottom of the two mounting seats is fixedly connected to the connecting rods on the top of the two movable blocks respectively. The positioning clamp is detachably connected to the top of the mounting seat by bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The rotating base of this utility model is connected to the track slide via a rotating bearing, allowing free rotation and adjustment of the processing angle without disassembling the workpiece, thus meeting the processing requirements of punching and shearing machines for different workpiece orientations. The rotating base can slide along the moving track, and the moving base moves rapidly on the positioning table surface via bottom rollers. Combined with the threaded drive of the threaded rod, precise adjustment of the lateral distance between the two positioning components is achieved, adapting to the positioning requirements of workpieces of different sizes. The threaded rod provides driving force, and the first guide rod provides guidance for the moving base, preventing offset or shaking during adjustment and ensuring the accuracy of the relative position of the two positioning components. By connecting the drive threaded rod through gears or keys and amplifying torque through mechanical transmission, workers can easily adjust the spacing of the moving base by simply turning the handle, reducing labor intensity and eliminating the need for additional auxiliary tooling. By adjusting the angle of the rotating base, multi-angle punching and shearing of workpieces can be completed on the same machine, avoiding the accuracy loss caused by multiple clamping in traditional processes and improving processing consistency. In the clamping state, the moving base or rotating base can be directly pushed to drive the workpiece to rotate around the track slide or translate along the moving track, realizing continuous operation of "positioning-adjustment-processing" and reducing the turnaround time between processes.

[0013] 2. The positioning component of this utility model has a bidirectional lead screw and a second guide rod forming a "lead screw drive + guide rod limiting" structure. The moving block only moves along the axial direction, ensuring that the positioning clamp moves horizontally, avoiding tilting, improving the stability during clamping, and reducing the displacement error of the workpiece during punching and shearing. The positioning clamp is automatically controlled by a motor, replacing the traditional manual knob or lead screw adjustment, shortening the clamping time, and is especially suitable for mass production scenarios. The positioning clamp is connected to the mounting base by bolts, and different types of clamps can be quickly changed according to the shape of the workpiece (such as flat plate, cylinder, irregular part, etc.), reducing equipment changeover time.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides the following technical solution:

[0020] like Figure 1-3 As shown, a multi-angle adjustable workpiece positioning structure for a punching and shearing machine in this embodiment includes a positioning platform 1, a positioning component 2, and a positioning clamp 4. Two positioning components 2 are provided on the top of the positioning platform 1, and a rotating base 5 and a movable base 6 are respectively provided on the bottom of the two positioning components 2. The positioning clamp 4 is provided on the top of the positioning component 2, and a movable track 3 is provided on the top surface of the positioning platform 1. The rotating base 5 is slidably disposed inside the movable track 3.

[0021] A threaded rod 7 and a first guide rod 8 are provided between the rotating base 5 and the movable base 6. One end of the first guide rod 8 is fixedly connected to the side of the rotating base 5, and the other end of the first guide rod 8 passes through the movable base 6 and is slidably connected to the movable base 6. One end of the threaded rod 7 is rotatably connected to the side of the rotating base 5, and the other end of the threaded rod 7 passes through the movable base 6 and is threadedly connected to the movable base 6. A track slide 9 is provided in the middle of the bottom surface of the rotating base 5. The top of the track slide 9 is connected to the rotating base 5 through a rotary bearing. The rotating base 5 is slidably set in the movable track 3 through the track slide 9. A handle 11 is provided on one side of the rotating base 5. The handle 11 passes through the rotating base 5 and is connected to one end of the threaded rod 7. A roller 10 is provided on the bottom surface of the movable base 6.

[0022] Specifically, the rotating base 5 is connected to the track slide 9 via a rotating bearing, allowing it to rotate freely and adjust the processing angle without disassembling the workpiece, thus meeting the processing needs of the punching and shearing machine for different workpiece orientations. The rotating base 5 can slide along the moving track 3, and the moving base 6 moves rapidly on the surface of the positioning table 1 via bottom rollers 10. Combined with the threaded drive of the threaded rod 7, it achieves precise adjustment of the lateral distance between the two positioning components 2, adapting to the positioning requirements of workpieces of different sizes. The threaded rod 7 provides the driving force, and the first guide rod 8 provides guidance for the moving base 6, preventing offset or shaking during adjustment and ensuring the accuracy of the relative positions of the two positioning components 2. The throttle 11 is connected to the drive threaded rod 7 via gears or keys, and the torque is amplified by mechanical transmission. The worker only needs to turn the handle lightly to adjust the spacing of the moving base 6, reducing labor intensity and eliminating the need for additional auxiliary tooling. By adjusting the angle position of the rotating base 5, multi-angle punching and shearing of the workpiece can be completed on the same machine, avoiding the accuracy loss caused by multiple clamping in traditional processes and improving processing consistency. In the clamping state, the moving base 6 or the rotating base 5 can be directly pushed to drive the workpiece to rotate around the track slide 9 or translate along the moving track 3, realizing continuous operation of "positioning-adjustment-processing" and reducing the turnaround time between processes.

[0023] The positioning assembly 2 is externally provided with a housing 12. Inside the housing 12 are a bidirectional lead screw 14 and a second guide rod 15. The two ends of the second guide rod 15 are fixedly connected to the inside of the housing 12, and the two ends of the bidirectional lead screw 14 are rotatably connected to the inside of the housing 12. Inside the housing 12 are two moving blocks 16, each with two through holes. The moving block 16 is slidably connected to the second guide rod 15 through one through hole and threadedly connected to the bidirectional lead screw 14 through the other through hole. A motor 13 is provided on one side of the housing 12, and the output shaft of the motor 13 is connected to one end of the bidirectional lead screw 14. A connecting rod 17 is provided on the top of the moving block 16. A sliding groove 19 is provided on the top surface of the housing 12, through which the connecting rod 17 passes. Two mounting seats 18 are provided on the top surface of the housing 12, and the bottoms of the two mounting seats 18 are fixedly connected to the connecting rods 17 on the top of the two moving blocks 16, respectively. The positioning clamp 4 is detachably connected to the top of the mounting seats 18 by bolts.

[0024] Specifically, the bidirectional lead screw 14 inside the positioning component 2 and the second guide rod 15 form a "lead screw drive + guide rod limit" structure. The moving block 16 moves only along the axial direction to ensure that the positioning clamp 4 moves horizontally, avoids tilting, improves the stability during clamping, and reduces the displacement error of the workpiece during punching and shearing. The motor 13 automatically controls the positioning clamp 4, replacing the traditional manual knob or lead screw adjustment, shortening the clamping time, which is especially suitable for mass production scenarios. The positioning clamp 4 is connected to the mounting base 18 by bolts, and different types of clamps can be quickly changed according to the shape of the workpiece (such as flat plate, cylinder, irregular part, etc.), reducing the equipment changeover time.

[0025] The working principle of the above is as follows: Place the workpiece to be processed by the punching and shearing machine above the positioning component 2. Rotate the handle 11 according to the size of the workpiece. The handle 11 drives the threaded rod 7 to rotate, thereby moving the movable base 6 towards the rotating base 5. After moving to match the size of the workpiece, stop rotating the handle 11 and drive the motor 13. The output shaft of the motor 13 drives the bidirectional lead screw 14 to rotate, thereby moving the two movable blocks 16 towards each other. The movement of the movable blocks 16 causes the positioning clamp 4 to clamp and position the workpiece. When it is necessary to adjust the angle of the workpiece, slide the movable base 6 to drive the two positioning components 2 to slide and rotate around the track slide 9. Thus, the angle of the workpiece can be adjusted without releasing the workpiece clamping state. The position of the workpiece can be adjusted by pushing the rotating base 5 to move the rotating base 5 and the movable base 6 along the direction of the moving track 3.
