Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a right-angle workpiece positioning device that is easy to adjust. Background Technology

[0002] Right-angle workpiece positioning devices are important auxiliary equipment in machining, assembly, and welding, primarily used to determine the accurate position of right-angle workpieces during processing, ensuring machining precision and quality. This device typically includes the following key structures:

[0003] 1. Positioning reference surfaces, made of rigid material, are two perpendicular surfaces used to fit against the right-angled edge of the workpiece to form a positioning reference.

[0004] 2. Adjustment mechanism, commonly including lead screws and nuts, guide rails and sliders, is used to adjust the position or spacing of the positioning reference surface;

[0005] 3. Locking devices, such as bolts and hydraulic clamps, are used to fix the adjusted positioning structure and prevent displacement during processing;

[0006] 4. Auxiliary positioning elements, including positioning pins, stops, sensors, etc., are used to further restrict the workpiece's degrees of freedom and improve positioning accuracy.

[0007] Currently, to meet the positioning requirements of different workpieces, manufacturers have adopted various types of right-angle workpiece positioning devices. Some devices adopt a fixed structure, using pre-designed fixtures to position workpieces of specific sizes, providing high stability; others employ a manual adjustment structure, allowing operators to fine-tune the positioning reference surface via knobs or handles; a few high-end devices are equipped with electric adjustment systems, enabling automated positioning and adjustment.

[0008] However, the above-described implementation still has the following problems. In terms of tooling adaptability, fixed positioning devices cannot meet the needs of rapid switching between multiple workpiece specifications. When processing right-angle workpieces of different sizes, it is necessary to frequently change the entire set of fixtures, which is unchanging and costly. In addition, the positioning structure of existing positioning devices is mostly difficult to disassemble. When components are damaged or the positioning method needs to be changed, it is impossible to perform rapid repairs or function switching. To address this problem, this application proposes a solution: designing a right-angle workpiece positioning device with a positioning structure that is easy to disassemble and adjust. This device can quickly adapt to workpieces of different specifications, significantly improve positioning efficiency and flexibility, and reduce maintenance costs and operational difficulty. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides an easily adjustable right-angle workpiece positioning device, which solves the problem that fixed positioning devices cannot meet the needs of rapid switching between workpieces of various specifications. When processing right-angle workpieces of different sizes, it is necessary to frequently change the entire set of fixtures, which is inconvenient to adjust and costly. In addition, the positioning structure of existing positioning devices is mostly difficult to disassemble, and when components are damaged or the positioning method needs to be changed, it is impossible to perform rapid repairs or function switching.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] An easily adjustable right-angle workpiece positioning device includes a right-angle frame. Two connecting frames are provided on the surface of the right-angle frame. Each connecting frame contains a clamping block. Each connecting frame has a screw threaded into it. A slider is fixedly connected to the upper surface of each clamping block. A limit block is movably engaged within each connecting frame. A return spring is fixedly connected to the opposite face of each limit block. Rubber pads are fixedly connected to the opposite back faces of each clamping block. Each clamping block is rotatably connected to two screws.

[0012] Preferably, the inner walls of both connecting frames are provided with sliding grooves, and the two sliding grooves are respectively movably connected to the two sliders. The upper surfaces of the two limiting blocks are fixedly connected with push blocks. The back sides of the two connecting frames are provided with slots, and the two slots are respectively movably engaged with the two limiting blocks.

[0013] Preferably, the two reset springs are fixedly connected to the two slots, the upper surface of the right-angle frame is provided with two sets of slots, the two sets of slots are respectively movably engaged with the two connecting brackets, the inner walls of the two sets of slots are provided with limit grooves, and the two sets of limit grooves are respectively movably engaged with the two limit blocks.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the position of the connecting frame needs to be adjusted, push the push block to move the fixed limit block together, compressing the return spring. At this time, the limit block will disengage from the limit groove, opening the limit and allowing the connecting frame to be disassembled. The position of the connecting frame can then be adjusted as needed. The overall disassembly is convenient and the position adjustment is easy. The modular design reduces the later maintenance cost, meets the usage needs, and improves the overall applicability and flexibility.

[0016] 2. During use, the close contact between the reference plane of the right-angle frame and the right-angle side of the workpiece restricts the two degrees of freedom of the workpiece in the plane, ensuring that the workpiece is in the preset right-angle position. At this time, rotating the screw will drive the clamping block connected to it to move together. The clamping block is fixed with a slider to ensure the stability during the movement. The rubber pad enhances the friction with the workpiece. Rotating the screw drives the clamping block to limit and fix the workpiece, avoiding the workpiece from shifting due to vibration, external force or other factors during processing.

[0023] This application provides an easily adjustable right-angle workpiece positioning device, effectively solving the problem that fixed positioning devices cannot meet the rapid switching requirements of workpieces of various specifications. When processing right-angle workpieces of different sizes, it is necessary to frequently change the entire set of fixtures, which is inconvenient to adjust and costly. In addition, the positioning structure of existing positioning devices is mostly difficult to disassemble, and when components are damaged or the positioning method needs to be changed, it is impossible to quickly repair or switch functions. This application designs a right-angle workpiece positioning device with a positioning structure that is easy to disassemble and adjust. This device can quickly adapt to workpieces of different specifications, significantly improve positioning efficiency and flexibility, and at the same time reduce maintenance costs and operating difficulty.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that fixed positioning devices cannot meet the rapid switching requirements of workpieces of various specifications. When processing right-angle workpieces of different sizes, it is necessary to frequently change the entire set of fixtures, which is inconvenient to adjust and costly. In addition, the positioning structure of existing positioning devices is mostly difficult to disassemble. When components are damaged or the positioning method needs to be changed, it is impossible to perform rapid repair or function switching. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides an easily adjustable right-angle workpiece positioning device, including a right-angle frame 1. Two connecting brackets 2 are provided on the surface of the right-angle frame 1. Each connecting bracket 2 contains a clamping block 3, and each connecting bracket 2 is threaded with a screw 4. A slider 10 is fixedly connected to the upper surface of each clamping block 3. A limit block 9 is movably engaged within each connecting bracket 2. A return spring 13 is fixedly connected to the opposite face of each limit block 9. A rubber pad 11 is fixedly connected to the opposite back face of each clamping block 3. Each clamping block 3 is rotatably connected to two screws 4. When the position of the connecting bracket 2 needs to be adjusted, pushing the push block 8 moves the fixed limit block 9 together, compressing the return spring 13. At this time, the limit block 9 disengages from the limit groove 6, opening the limit, and the connecting bracket 2 can be disassembled. The position of the connecting bracket 2 can then be adjusted as needed. The overall disassembly is convenient, facilitating position adjustment. The modular design reduces subsequent maintenance costs, meets usage needs, and improves overall applicability and flexibility.

[0027] Both connecting frames 2 have sliding grooves 7 on their inner walls, and the two sliding grooves 7 are movably connected to the two sliders 10 respectively. Push blocks 8 are fixedly connected to the upper surfaces of the two limiting blocks 9. The two connecting frames 2 have slots 12 on their opposite sides, and the two slots 12 are movably engaged with the two limiting blocks 9 respectively. Two return springs 13 are fixedly connected to the two slots 12 respectively. The right-angle frame 1 has two sets of slots 5 on its upper surface, and the two sets of slots 5 are movably engaged with the two connecting frames 2 respectively. Limit grooves 6 are provided on the inner walls of the two sets of slots 15, and the two sets of limit grooves 6 are respectively engaged with the two limiting blocks 9. The position block 9 is movable and latched. During use, the reference surface of the right-angle frame 1 is tightly attached to the right-angle side of the workpiece, restricting the two degrees of freedom of the workpiece in the plane and ensuring that the workpiece is in the preset right-angle position. At this time, rotating the screw 4 will drive the clamping block 3 connected to it to move together. The clamping block 3 is fixed by the slider 10 on it to ensure the stability during the movement. The rubber pad 11 enhances the friction with the workpiece. By rotating the screw 4, the clamping block 3 is fixed to the workpiece to limit and fix it, so as to avoid the workpiece from shifting due to vibration, external force and other factors during the processing.

[0028] Among them, the right-angle frame 1 fits with the right-angle side of the workpiece through mutually perpendicular reference planes, restricts two degrees of freedom in the workpiece plane, and determines the preset right-angle position of the workpiece. It is the core component of the positioning reference of the device.

[0029] The connecting frame 2 is installed on the right-angle frame 1 and is used to install components such as the clamping block 3. Its position can be adjusted by disassembly to adapt to workpieces of different specifications and improve the flexibility of the device.

[0030] The clamping block 3 is inside the connecting frame 2 and is moved by the screw 4. The rubber pad 11 on its back increases the friction with the workpiece and works with the right-angle frame 1 to limit and fix the workpiece to prevent it from shifting during processing.

[0031] The screw 4 is threaded into the connecting frame 2. When it rotates, it drives the clamping block 3 to move, thereby clamping or releasing the workpiece. It is the driving component for adjusting the position of the clamping block 3.

[0032] The slot 5 is opened on the right-angle frame 1 and is movably engaged with the connecting frame 2. It is used to initially position the connecting frame 2 and, together with the limiting slot 6 and other components, realizes the fixation and adjustment of the position of the connecting frame 2.

[0033] The limiting groove 6 is on the inner wall of the slot 5 and engages with the limiting block 9 to restrict the movement of the connecting frame 2. When the push block 8 is pushed to make the limiting block 9 disengage from the limiting groove 6, the limiting can be released so that the position of the connecting frame 2 can be adjusted.

[0034] The slide 7 is located on the inner wall of the connecting frame 2 and is movably connected to the slider 10, providing guidance for the movement of the slider 10, ensuring the stability of the clamping block 3 during movement, and improving positioning accuracy;

[0035] Push block 8 is fixed on the upper surface of limit block 9. Pushing push block 8 can drive limit block 9 to move, compressing reset spring 13, causing limit block 9 to disengage from limit groove 6, thereby opening the limit of connecting frame 2.

[0036] The limiting block 9 is movable and snapped into the connecting frame 2. When it is snapped into the limiting groove 6, it fixes the position of the connecting frame 2. The snapping can be released by moving the push block 8. It is a key component for limiting and disassembling the connecting frame 2.

[0037] The slider 10 is fixed on the upper surface of the clamping block 3 and cooperates with the slide groove 7 in the connecting frame 2 to ensure the stability of the clamping block 3 when it moves and avoid shaking that affects the positioning accuracy of the workpiece.

[0038] The rubber pad 11 is fixed to the back of the clamping block 3. By increasing the friction with the workpiece, the clamping block 3 enhances the fixing effect of the workpiece and prevents the workpiece from shifting due to external force during processing.

[0039] The second slot 12 is on the back of the connecting frame 2 and is movably engaged with the limit block 9, providing an installation position for the limit block 9. In conjunction with the reset spring 13, the limit block 9 can automatically reset after the limit is released.

[0040] The reset spring 13 is fixedly connected to the second slot 12. When the push block 8 is pushed to compress the spring and the limit block 9 is disengaged from the limit slot 6, the spring resets when the push block 8 is released, and the limit block 9 returns to the snap-fit ​​state.

[0041] Working principle:

[0042] During use, the close contact between the reference surface of the right-angle frame 1 and the right-angle side of the workpiece restricts the two degrees of freedom of the workpiece in the plane, ensuring that the workpiece is in the preset right-angle position. At this time, rotating the screw 4 will drive the clamping block 3 connected to it to move together. The clamping block 3 is fixed by the slider 10 to ensure the stability during the movement. The rubber pad 11 enhances the friction with the workpiece. Rotating the screw 4 drives the clamping block 3 to limit and fix it to the workpiece, avoiding the workpiece displacement caused by vibration, external force and other factors during processing. When it is necessary to adjust the position of the connecting frame 2, push the push block 8 to drive the fixed limit block 9 to move together, compressing the return spring 13. At this time, the limit block 9 will disengage from the limit groove 6, opening the limit, and the connecting frame 2 can be disassembled. At this time, the position of the connecting frame 2 can be adjusted according to the needs. The whole disassembly is convenient and the position adjustment is convenient. The modular design reduces the maintenance cost in the later stage, meets the needs of use, and improves the overall applicability and flexibility.

[0043] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
