Description

Technical Field

[0001] This utility model relates to the field of machining, specifically to a double-rail sliding inclined plane positioning device with adjustable pitch angle. Background Technology

[0002] In machining, inspection, and assembly, precise and stable positioning of parts with complex surfaces, especially those with inclined planes, is crucial for ensuring the quality of subsequent processes. Current technologies commonly employ a combination of fixed positioning blocks or simple adjustable support pins to construct the positioning surface. However, these traditional methods have significant limitations. When using a single large positioning block, the pitch angle of the positioning surface is fixed, making it unsuitable for changes in part design or angle differences between different part models, resulting in extremely poor flexibility. If multiple independently adjustable small positioning blocks or support pins are used to simulate a theoretical inclined plane, it is difficult to ensure that the height of each positioning point is adjusted precisely in actual operation, thus failing to form a continuous, uniform, and ideal contact surface. This often leads to the positioned part only contacting some positioning points, resulting in misalignment and stress concentration. Not only is positioning accuracy difficult to guarantee, but stability is also poor, easily causing vibration or displacement during machining, affecting machining quality, and even risking scratches on the finished surface of the part. Therefore, the industry urgently needs a stable positioning device that can quickly and accurately achieve stepless adjustment of the pitch angle and ensure surface contact between the positioning surface and the part to overcome the shortcomings of existing technologies. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a dual-rail sliding inclined plane positioning device with adjustable pitch angle, comprising:

[0004] The slide rail assembly is fixed to the platform plate;

[0005] The base plate of the bracket is slidably mounted on the slide rail assembly via a guide slider, so that the base plate of the bracket can slide back and forth along the slide rail assembly;

[0006] Two support bases are disposed opposite to each other on the support base plate;

[0007] A positioning bracket is rotatably mounted between two bracket bases via a bracket shaft, allowing the positioning bracket to pitch around the bracket shaft. The horizontal part of the positioning bracket is connected to a support platform for placing the positioned component.

[0008] An adjustable seat plate is located on the base plate of the bracket at one end near the support platform;

[0009] An adjusting seat is rotatably mounted on the adjusting seat plate via an adjusting seat shaft;

[0010] Several perforated gaskets are stacked on the adjusting seat;

[0011] A locking screw is threaded onto the support platform, and its free end can pass through the perforated gasket and connect to the threaded hole on the adjusting seat, thereby fixing the positioning bracket at the desired pitch angle.

[0012] As a preferred embodiment of this application, both sides of the support platform are equipped with detachable bottom horizontal positioning blocks via first mounting bases and screws on the first mounting bases, for supporting the bottom horizontal surface of the positioned component.

[0013] As a preferred embodiment of this application, the rear end of the support platform is equipped with a detachable bottom inclined surface positioning block via a second mounting base and screws on the second mounting base, for supporting the bottom inclined surface of the positioned component.

[0014] As a preferred embodiment of this application, the positioning bracket has detachable side straight-face positioning blocks installed on the upper and lower rear sides via mounting plates and screws on the mounting plates, for positioning the front straight surface of the positioned part.

[0015] As a preferred embodiment of this application, the upper end of the positioning bracket is provided with an extension arm, and a clamping bolt is threaded onto the extension arm for clamping the inclined surface of the positioned part.

[0016] As a preferred embodiment of this application, the platform plate is further provided with a base plate positioning seat, and the bracket base plate is provided with positioning pins or positioning screws for positioning the bracket base plate on the base plate positioning seat.

[0017] As a preferred embodiment of this application, the support base plate is provided with a handle at its front end.

[0018] As a preferred embodiment of this application, the slide rail assembly has a double-rail structure.

[0019] Compared with the prior art, the adjustable pitch angle dual-rail sliding inclined plane positioning device provided in this application has the following significant advantages:

[0020] 1. Significantly Improved Positioning Accuracy and Stability: The overall pitch and rotation of the positioning bracket is achieved through the bracket shaft, and fine-tuning and locking are performed using a combination of locking screws and perforated washers, allowing for precise setting and fixing of the required angle. This method enables the support platform to form a complete and angularly precise reference plane, achieving full surface contact with the bottom surface of the positioned part. This avoids uneven stress and positioning instability caused by multi-point support, greatly improving positioning rigidity and accuracy.

[0021] 2. High adaptability and convenient adjustment: The pitch angle of the device is infinitely adjustable to adapt to the positioning needs of parts at different angles. Meanwhile, the sliding design of the slide rail assembly and the support base plate, combined with the base plate positioning seat, enables the device to have coarse adjustment capabilities for forward and backward positions. Multiple detachable positioning blocks and clamping bolts constitute a modular positioning and clamping system, which can quickly adapt to different types of parts, achieving rapid production changeover and excellent versatility.

[0022] 3. High operating efficiency and protection of parts: The integrated sliding and angle adjustment function replaces the tedious process of adjusting multiple positioning blocks one by one, making operation simple and quick, and greatly reducing the operator's labor intensity and adjustment time. The optimized surface contact positioning method effectively disperses clamping force and machining force, reducing the risk of crushing or scratching the surface of the parts, and is particularly beneficial to protecting the surface quality of the finished parts.

[0023] In summary, this application effectively solves the problems of poor flexibility, low accuracy, insufficient stability and low efficiency of existing positioning technologies, and has excellent overall performance. Attached Figure Description

[0033] Reference Appendix Figure 1 -Appendix Figure 4 This application provides a dual-rail sliding inclined plane positioning device with adjustable pitch angle to overcome the aforementioned limitations. The device mainly includes a slide rail assembly 1, a support base plate 3, a support base 4, a positioning bracket 5, an adjusting seat plate 7, an adjusting seat 8, a perforated gasket 12, and a locking screw 13. The slide rail assembly 1 is fixedly mounted on the platform plate, serving as the basic support structure for the entire device. The bottom of the support base plate 3 is connected to the slide rail assembly 1 via a guide slider, allowing the support base plate 3 to slide back and forth along the slide rail assembly 1, thereby flexibly adjusting the horizontal position of the device. Two support bases 4 are arranged opposite each other on the support base plate 3. The positioning bracket 5 is rotatably mounted between the two support bases 4 via a support shaft 6, allowing the positioning bracket 5 to pitch around the support shaft 6, thus adapting to different angle positioning requirements. The horizontal portion of the positioning bracket 5 is connected to a support platform 11 for placing the positioned component 10. An adjusting seat plate 7 is provided at one end of the support base plate 3 near the support platform 11, and the adjusting seat 8 is rotatably mounted on the adjusting seat plate 7 via an adjusting seat shaft 9. Several perforated shims 12 are stacked on the adjusting seat 8, and locking screws 13 are threaded onto the support platform 11. The free end of the locking screw 13 can pass through the perforated shims 12 and connect with the threaded hole on the adjusting seat 8. By adjusting the number of perforated shims 12 or the tightness of the locking screws 13, the pitch angle of the positioning bracket 5 can be changed and fixed at that angle, thereby achieving precise positioning and stable support for the positioned part 10.

[0034] In one embodiment of this application, detachable bottom horizontal positioning blocks 14 are mounted on both sides of the support platform 11 via first mounting seats and screws on the mounting seats. These bottom horizontal positioning blocks 14 are used to support the bottom horizontal surface of the positioned part 10, ensuring the stability of the positioned part in the horizontal direction. The detachable design allows for the replacement of suitable positioning blocks according to the size and shape of different parts, improving the versatility and adaptability of the device.

[0035] In one embodiment of this application, a detachable bottom inclined positioning block 15 is mounted on the rear end of the support platform 11 via a second mounting base and screws on the mounting base. This bottom inclined positioning block 15 is specifically designed to support the bottom inclined surface of the positioned component 10, working in conjunction with the bottom horizontal positioning block 14 to ensure the accurate positioning of the positioned component 10 in three-dimensional space. The detachable structure facilitates daily maintenance and quick replacement to adapt to various processing scenarios.

[0036] In one embodiment of this application, detachable side-face positioning blocks 16 are mounted on the upper and lower rear sides of the positioning bracket 5 via mounting plates and screws. These side-face positioning blocks 16 are used to position the front straight surface of the positioned part 10. By being arranged vertically, they effectively constrain the lateral movement of the positioned part 10, preventing offset during processing, thereby improving the reliability and accuracy of positioning.

[0037] In one embodiment of this application, the upper end of the positioning bracket 5 is provided with an extension arm 17, and a clamping bolt 18 is threadedly connected to the extension arm 17. After the positioned part 10 is placed in place, the rear inclined surface of the positioned part 10 can be pressed by tightening the clamping bolt 18, thereby firmly fixing the positioned part 10 on the support table 11, avoiding displacement caused by vibration or external force during processing, and ensuring processing stability.

[0038] In one embodiment of this application, the platform plate is further provided with a base plate positioning seat 2, and the bracket base plate 3 is provided with positioning pins or positioning screws. When the bracket base plate 3 slides to the required position, the bracket base plate 3 can be quickly fixed on the base plate positioning seat 2 by the positioning pins or positioning screws to prevent accidental movement and ensure the repeatability of positioning and operational safety.

[0039] In one embodiment of this application, a handle is provided at the front end of the bracket base plate 3. This design allows the operator to easily push and pull the bracket base plate 3 via the handle, enabling it to slide smoothly along the slide rail assembly 1, thereby simplifying the position adjustment process and improving operational efficiency and user-friendliness.

[0040] In one embodiment of this application, the slide rail assembly 1 adopts a double-rail structure. The double-rail design enhances the stability and load capacity of the device, better distributes weight, reduces deformation or wear that may occur with a single-rail structure, and ensures that the support base plate 3 slides smoothly and reliably, making it suitable for high-precision machining environments.

[0041] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
