[0001] This utility model belongs to the field of mechanical processing technology, specifically a high-precision mechanical processing positioning device. Background Technology

[0002] Electromechanical equipment refers to equipment that combines mechanical and electrical technologies. It is typically used in industrial production, building facilities, and automation systems. This type of equipment integrates mechanical parts and electrical components to achieve specific functions or operations. Examples include electric motors, generators, transformers, switchboards, servers, various control systems (such as PLC programmable logic controllers), sensors, and drives.

[0003] In the field of electromechanical equipment, existing machining positioning methods have certain limitations in scenarios requiring high precision. A search revealed a laser precision positioning method for machining (publication number CN112935785B, published on June 3, 2022). This method achieves precise positioning of the laser emitter through the cooperation of a laser tracker and a positioning steel plate. While this method provides high positioning accuracy, its applicability is limited, mainly suitable for specific types of machining scenarios, such as machining inside spherical tanks. Furthermore, the introduction of a laser system significantly increases equipment costs and operational complexity, limiting its widespread adoption in general machining scenarios. Therefore, existing technologies have room for improvement in meeting the current industrial demand for low-cost, high-efficiency, and widely adaptable new positioning devices. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this utility model provides a high-precision machining positioning device. The technical implementation is as follows: A high-precision machining positioning device includes a base, guide rails, a sliding table, positioning blocks, adjusting components, locking components, and a calibration module. The base is provided with a guide rail symmetrically arranged on its top, extending along the length of the base. The sliding table slides along the guide rails via grooves at its bottom. A positioning block for fixing the workpiece to be processed is provided on the top of the sliding table, and the positioning block is connected to the sliding table by bolts. An adjusting component is provided on one side of the sliding table to control the distance the sliding table moves along the guide rails. A set of locking components is provided at both ends of the base, located on both sides of the sliding table to fix its position. Furthermore, a calibration module is provided in the middle of the base to detect the displacement accuracy of the sliding table and output a feedback signal.

[0005] Optionally, the adjustment assembly includes a lead screw, a handwheel, and a limiting sleeve. The lead screw passes through the sliding table and is threaded into the sliding table. One end of the lead screw is rotatably connected to one side of the base, and the other end is provided with a handwheel. The handwheel is fixedly connected to the lead screw through a keyway. The limiting sleeve is fixedly installed on the other side of the base. A through hole adapted to the lead screw is opened in the limiting sleeve. Guide rods are provided on both sides of the lead screw to limit the axial movement of the lead screw.

[0006] Optionally, it also includes an elastic clamping plate, a pressure plate, and an adjusting bolt. An elastic clamping plate is provided on the top of the positioning block and is fixedly connected to the top of the positioning block. The pressure plate is located below the elastic clamping plate and is connected to the positioning block by an adjusting bolt. The adjusting bolt passes through the pressure plate and is threaded into the positioning block to adjust the clamping force of the pressure plate on the workpiece.

[0007] The locking assembly includes a locking block, an adjusting bolt, and guide rods. The locking block is mounted on one end of the base via the adjusting bolt, which is threaded through the base. One end of the adjusting bolt is rotatably connected to the locking block. Guide rods are provided at both ends of the locking block, which pass through the base and are fixedly connected to the locking block. When the adjusting bolt rotates, it moves the locking block closer to or away from the sliding table, thereby locking or unlocking the sliding table.

[0008] This invention has the following advantages: By setting the base as the main frame of the entire device, a stable installation foundation is provided for other components, effectively avoiding positioning deviations caused by external vibrations or impacts; the design of the guide rail and sliding table enables precise movement of the sliding table along a straight line, significantly improving positioning accuracy; the adjustment component, through the cooperation of the lead screw and handwheel, can achieve precise control of the sliding table displacement distance, while the design of the limit sleeve restricts the axial movement of the lead screw, further enhancing the reliability of the device; the locking component, through the linkage of the adjusting bolt and the locking block, can quickly lock or unlock the sliding table, simplifying the operation process.

[0009] This utility model solves the problems of limited applicability, high equipment cost, and complex operation in the prior art through the above-mentioned technical means, and meets the industrial field's demand for a new positioning device with low cost, high efficiency, and wide adaptability.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] This utility model provides a high-precision machining positioning device, the structure of which is shown in Figures 1 to 4, including a base 1, a guide rail 2, a sliding table 3, a positioning block 4, an adjusting component 5, and a locking component 6. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] The base 1 forms the main frame of the entire device, is rectangular in shape, and is made of high-strength aluminum alloy to ensure the overall rigidity and stability of the device. Two guide rails 2 are symmetrically arranged along the length of the top of the base 1. The guide rails 2 have a rectangular cross-section and their surfaces are precision ground to ensure the smooth movement of the sliding table 3. The sliding table 3 slides with the guide rails 2 through a groove at its bottom. A low-friction slider is installed in the groove, and grease is applied between the contact surfaces of the slider and the guide rail 2 to reduce movement resistance and extend service life. A positioning block 4 is provided on the top of the sliding table 3 to fix the workpiece to be processed. The positioning block 4 is connected to the sliding table 3 by bolts, and countersunk holes are provided at the connection points to prevent the bolt heads from protruding and affecting workpiece placement.

[0022] An adjustment component 5 is provided on one side of the sliding table 3. The adjustment component 5 is used to control the distance that the sliding table 3 moves along the guide rail 2. A set of locking components 6 is provided at both ends of the base 1. The locking components 6 are located on both sides of the sliding table 3 to fix the position of the sliding table 3.

[0023] Example 2

[0024] An adjustment component was added based on Embodiment 1, and the adjustment component was fixedly installed at the top of the base 1.

[0025] The specific structure of the adjusting component 5 is shown in Figure 2, including a lead screw 8, a handwheel 9, and a limiting sleeve 10. The lead screw 8 passes through the sliding table 3 and is threadedly engaged with it. One end of the lead screw 8 is rotatably connected to one side of the base 1 via a bearing, and the other end is equipped with a handwheel 9. The handwheel 9 is fixedly connected to the lead screw 8 via a keyway, ensuring that the handwheel 9 can drive the lead screw 8 to rotate synchronously when it rotates. The limiting sleeve 10 is fixedly installed on the other side of the base 1. The limiting sleeve 10 has a through hole adapted to the lead screw 8, and the inner wall of the through hole is provided with a wear-resistant bushing to limit the axial movement of the lead screw 8 and reduce the friction between the lead screw 8 and the limiting sleeve 10. Guide rods are symmetrically arranged on both sides of the lead screw 8, and the two ends of the guide rods are fixedly connected to the corresponding ends of the base 1. When the operator rotates the handwheel 9, the lead screw 8 rotates and, through threaded transmission, pushes the sliding table 3 along the guide rail 2 via the guide rods, thereby achieving precise control of the displacement distance of the sliding table 3.

[0026] A flexible clamping piece is provided on the top of the positioning block 4, and the flexible clamping piece is fixedly connected to the positioning block 4. The pressure plate is located below the flexible clamping piece and is connected to the positioning block 4 by an adjusting bolt. The adjusting bolt passes through the positioning block 4 and is rotatably connected to the pressure plate. Guide rods are fixedly connected to both sides of the pressure plate, passing through the positioning block 4 and fixedly connected to the pressure plate, for adjusting the clamping force of the pressure plate on the workpiece. When it is necessary to clamp the workpiece, the operator tightens the adjusting bolt, causing the pressure plate to move upward and apply clamping force to the workpiece. The flexible clamping piece then undergoes elastic deformation to adapt to the shape contour of the workpiece, thereby achieving stable fixation of workpieces of different shapes. The thread of the adjusting bolt adopts a fine thread design to improve the adjustment accuracy of the clamping force.

[0027] The specific structure of the locking assembly 6 is shown in Figure 3. The locking assembly 6 includes a locking block 11, an adjusting bolt 7, and guide rods. The locking block 11 is mounted at one end of the base 1 via the adjusting bolt 7, which is threaded through the base 1. One end of the adjusting bolt 7 is rotatably connected to the locking block 11. Guide rods are provided at both ends of the locking block 11, passing through the base 1 and fixedly connected to the locking block 11. When the operator rotates the adjusting bolt 7, it causes the locking block 11 to rotate, moving it closer to or away from the sliding table 3 via the guide rods. A rubber pad is provided on the inner side of the locking block 11, contacting the outer surface of the sliding table 3 to increase friction and prevent damage to the sliding table 3 during locking. Through this linkage design, the locking assembly 6 can lock or unlock the sliding table 3.

[0028] In practical applications, the operation process of this utility model is as follows: First, place the workpiece to be processed on the positioning block 4, and adjust the clamping force of the pressure plate on the workpiece by adjusting the bolts to firmly fix the workpiece. Then, turn the handwheel 9, and the rotation of the lead screw 8 will push the sliding table 3 to move along the guide rail 2 until the sliding table 3 reaches the target position. After confirming that the position of the sliding table 3 is correct, rotate the adjusting bolt 7, and the locking block 11 will move closer to the sliding table 3 by adjusting the bolt 7, thereby fixing the sliding table 3 in the current position. At this time, the sliding table 3 remains stable under the guidance of the guide rail 2, avoiding displacement deviation caused by external vibration or load changes. After processing is completed, reverse the adjusting bolt 7 to move the locking block 11 away from the sliding table 3, release the locking state of the sliding table 3, and then reset the sliding table 3 by using the handwheel 9, ready for the next processing operation.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
