Description

Technical Field

[0001] This utility model belongs to the field of machining and precision manufacturing technology, specifically a machining equipment with adjustable positioning accuracy for parts. Background Technology

[0002] In the machining of mechanical parts, positioning accuracy is one of the key factors affecting machining quality. Currently, there are some machining equipment on the market designed to improve the positioning accuracy of parts. These devices typically achieve positioning through complex adjustment mechanisms or high-precision sensors, but their structural designs are often relatively fixed, making it difficult to flexibly adjust them according to actual needs. Furthermore, such equipment may require frequent calibration during use, increasing operational time costs and maintenance difficulty.

[0003] For example, in existing technologies, some processing equipment uses multi-axis linkage mechanisms to achieve precise positioning of parts. However, such mechanisms are costly to manufacture and require a high level of skill from operators. Furthermore, due to their structural complexity, cumulative errors may occur during long-term operation, affecting the stability of positioning accuracy. These factors demonstrate the limitations of existing technologies in terms of flexibility and adaptability.

[0004] Therefore, we have made improvements and proposed a machining equipment with adjustable component positioning accuracy. Utility Model Content

[0007] The adjustment assembly includes a sliding unit and a driving unit. The sliding unit consists of multiple slide rails, each of which is embedded in the bottom of the mounting platform and fixed with bolts. The driving unit includes a gear set and a handle. The gear set meshes with the slide rails, and the handle drives the gear set to move by rotation, thereby causing the slide rails to slide along the bottom of the mounting platform. The positioning assembly includes a positioning block and an elastic clamping element. The positioning block is connected to the mounting platform through the sliding unit, and the elastic clamping element is located inside the positioning block to apply pressure to the components for precise positioning.

[0008] As a preferred technical solution of this application, the support frame includes a base and columns. The base is a rectangular plate structure with mounting holes at its four corners for fixing the equipment on the workbench. The columns are four metal rods of equal length, which are vertically welded to the four corners of the base and connected to the mounting platform by bolts at their tops. The mounting platform is a rectangular flat plate with multiple through holes on its surface for mounting clamps or auxiliary tools.

The end of the handle is provided with a scale, and the surface of the scale is marked with angle markings to indicate the rotation angle of the handle, thereby indirectly reflecting the movement distance of the slide rail.

[0012] As a preferred technical solution of this application, the top of the positioning block is provided with a locking bolt, which passes through the positioning block and is threadedly connected to the top of the slide rail, for fixing the positioning block on the slide rail after positioning is completed; the pressure of the elastic clamping member can be changed by adjusting the compression of the spring, specifically by tightening or loosening the adjusting nut on the pressure plate.

[0019] This utility model provides a processing equipment with adjustable positioning accuracy for parts, the structure of which is as follows: Figures 1 to 4 As shown in the accompanying drawings, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. The support frame 1 is the basic load-bearing part of the overall structure. Its base is a rectangular plate structure with mounting holes at each of the four corners. The base is fixed to the workbench with bolts. Four metal columns of equal length are vertically welded onto the base. The tops of the columns are connected to the mounting platform 2 with bolts to form a stable frame structure. The mounting platform 2 is a rectangular flat plate with multiple through holes on its surface for mounting clamps or auxiliary tools. A guide groove 9 is provided at the bottom of the mounting platform 2. The guide groove 9 is a rectangular groove structure with ball bearings inside. The top of the slide rail 3 is embedded in the guide groove 9, and low-friction sliding is achieved through the ball bearings.

[0020] The slide rail 3, as the core component of the sliding unit, is embedded in the bottom of the mounting platform 2 and fixed with bolts. Its two ends are connected to limit blocks 7 via threads to restrict the movement range of the slide rail 3. The number of slide rails 3 can be set to multiple according to actual needs, and each slide rail 3 is meshed with a gear set 8. The gear set 8 includes a driving gear and a driven gear. The driving gear is coaxially connected to the handle 4, and the driven gear meshes with the rack of the slide rail 3. Precise movement of the slide rail 3 is achieved through gear transmission. A dial is provided at the end of the handle 4, with angle markings on its surface to indicate the rotation angle of the handle 4, thereby indirectly reflecting the movement distance of the slide rail 3.

[0021] The positioning block 5 is slidably connected to the slide rail 3 via a groove, which matches the top of the slide rail 3 to ensure smooth movement of the positioning block 5 along the slide rail 3. A locking bolt 10 is provided on the top of the positioning block 5, passing through the positioning block 5 and threadedly connected to the top of the slide rail 3, used to fix the positioning block 5 to the slide rail 3 after positioning. An elastic clamping element 6 is provided on the inner side of the positioning block 5, comprising a spring and a pressure plate. One end of the spring is fixedly connected to the inner wall of the positioning block 5, and the other end is fixedly connected to the pressure plate. An anti-slip pad is provided on the surface of the pressure plate to increase friction with the components. The pressure of the elastic clamping element 6 can be changed by adjusting the compression of the spring, specifically by tightening or loosening the adjusting nut on the pressure plate.

[0022] Reinforcing ribs 11 are welded between the columns of the support frame 1. The reinforcing ribs 11 are rectangular metal plates, and their two ends are welded to the two adjacent columns respectively to improve the overall rigidity of the support frame 1. Protective baffles 12 are fixed to the edges of the mounting platform 2 by bolts. The protective baffles 12 are arranged around the perimeter of the mounting platform 2 to prevent parts from accidentally slipping during processing.

[0023] During use, the parts to be processed are first placed on the mounting platform 2, and the position of the positioning block 5 is adjusted according to the size and shape of the parts. By rotating the handle 4, the driving gear drives the driven gear to rotate, and the driven gear meshes with the rack of the slide rail 3, thereby driving the slide rail 3 to slide along the guide groove 9. The movement of the slide rail 3 causes the positioning block 5 to move along the slide groove until the inner elastic clamping member 6 of the positioning block 5 contacts the surface of the parts. The spring in the elastic clamping member 6 applies uniform pressure through the pressure plate, so that the parts are firmly fixed on the mounting platform 2. During the adjustment process, the scale at the end of the handle 4 can visually display the movement distance of the slide rail 3, thereby ensuring positioning accuracy. After positioning is completed, the positioning block 5 is fixed to the slide rail 3 by the locking bolt 10 to avoid positioning offset caused by equipment vibration.

[0024] When machining parts of different sizes or shapes, the position of the positioning block 5 can be readjusted by loosening the locking bolt 10, and the above operation steps can be repeated. In addition, the pressure of the elastic clamping member 6 can be adjusted according to the material of the parts or the machining requirements. The compression of the spring can be changed by tightening or loosening the adjusting nut on the pressure plate, thereby adapting to different machining needs.

[0025] The entire device operates based on a mechanical transmission and sliding fit design. The meshing transmission between the gear set 8 and the slide rail 3 enables precise movement of the slide rail 3, while the engagement between the slide rail 3 and the ball bearings in the guide groove 9 reduces frictional resistance during sliding, improving the smoothness and accuracy of adjustment. The positioning block 5, through its sliding connection with the slide rail 3 via a groove, ensures flexibility in position adjustment, while the locking bolt 10 enables quick fixation. The design of the elastic clamping element 6 allows the components to withstand uniform pressure when fixed, avoiding positioning errors caused by uneven external forces.

[0026] This invention, through the aforementioned structural design, effectively solves the problems of inflexible adjustment of positioning accuracy, complex operation due to frequent calibration, and high manufacturing costs in the prior art. The reinforcing ribs 11 and protective baffles 12 of the support frame 1 further enhance the safety and stability of the equipment and extend its service life.

[0027] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model will be further explained below in conjunction with a specific application scenario.

[0028] First, when machining rectangular metal parts, the parts to be machined are placed on the mounting platform 2, and the position of the positioning block 5 is adjusted according to the geometric dimensions of the parts. By rotating the handle 4, the driving gear drives the driven gear to rotate, and the driven gear meshes with the rack of the slide rail 3, thereby driving the slide rail 3 to slide along the guide groove 9. The movement of the slide rail 3 drives the positioning block 5 to move synchronously through the slide groove until the elastic clamping member 6 on the inner side of the positioning block 5 contacts the surface of the part. During this process, the scale at the end of the handle 4 can intuitively display the rotation angle, thereby indirectly reflecting the movement distance of the slide rail 3, ensuring that the positioning accuracy meets the machining requirements. After the position adjustment is completed, the positioning block 5 is fixed to the slide rail 3 by the locking bolt 10 to prevent positioning offset caused by equipment vibration.

[0029] Secondly, when processing parts of different sizes or shapes, the position of the positioning blocks 5 can be readjusted by loosening the locking bolts 10. For example, when processing round parts, multiple positioning blocks 5 can be moved along the slide rails 3 to suitable positions to adapt to the contour of the round workpiece. After adjustment, the locking bolts 10 are tightened again to fix the positioning blocks 5. In addition, the pressure of the elastic clamping element 6 can be adjusted according to the material of the parts or processing requirements. Specifically, by tightening or loosening the adjusting nut on the pressure plate, the compression of the spring is changed, thereby adjusting the pressure applied by the elastic clamping element 6, ensuring that the parts are not deformed due to excessive pressure or displaced due to insufficient pressure when fixed.

[0030] Furthermore, during the machining process, the ball joint design within the slide rail 3 and guide groove 9 significantly reduces frictional resistance during sliding, improving the smoothness and precision of adjustment. This low-friction design allows operators to more precisely control the movement distance of the slide rail 3, thereby achieving accurate positioning of parts. Simultaneously, the sliding connection between the positioning block 5 and the slide rail 3 via the groove ensures flexibility in position adjustment, while the locking bolt 10 provides a quick-fixing function, reducing the operational complexity caused by frequent calibration.

[0031] Finally, the reinforcing ribs 11 and protective baffles 12 of the supporting frame 1 play a crucial auxiliary role throughout the entire processing. The reinforcing ribs 11, connected to adjacent columns by welding, significantly improve the overall rigidity of the supporting frame 1, effectively preventing frame deformation due to long-term operation. The protective baffles 12 are arranged around the mounting platform 2 to prevent components from accidentally slipping during processing, further enhancing the safety and stability of the equipment. These structural designs not only extend the service life of the equipment but also provide operators with a more reliable working environment.

[0032] In summary, this utility model, through the combination of the above steps and principles, achieves flexible positioning and precise processing of parts of different sizes and shapes. Its operating principle, based on mechanical transmission and sliding fit design, simplifies the operation process and reduces manufacturing costs. Furthermore, through optimized structural design, it solves the problems of inflexible adjustment of positioning accuracy, complex operation due to frequent calibration, and high manufacturing costs in existing technologies, demonstrating significant practicality and innovation.
