Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and in particular relates to a positioning device for mechanical equipment processing. Background Technology

[0002] In the field of mechanical equipment processing, the performance of positioning devices directly affects processing accuracy and production efficiency. Currently, most mainstream positioning devices for mechanical equipment processing rely on manual operation of the clamping mechanism. This not only requires operators to continuously monitor the positioning status, consuming a significant amount of manpower, but is also prone to positioning deviations due to uneven manual operation force and delayed response, leading to processing errors and, in severe cases, even workpiece scrapping, increasing production losses. Furthermore, the mechanical equipment processing process generates a large amount of metal shavings, waste, and other debris. Existing positioning devices generally lack a chip removal structure linked to the positioning action. These waste materials easily accumulate on the surface of the positioning frame and in key areas such as the slides and clamping components, hindering the smooth sliding of the positioning components and affecting the accuracy of clamping or releasing actions. Moreover, manually cleaning the accumulated waste requires pausing the processing flow, causing processing interruptions and significantly reducing overall production efficiency. Therefore, we propose a positioning device for mechanical equipment processing. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing a positioning device for machining equipment, thereby ensuring the stability of the equipment during the machining process and avoiding machining errors caused by positioning offset.

[0004] In view of this, the present invention provides a positioning device for machining machinery, including a positioning frame, a positioning component, a driving component, and a chip removal part. The positioning frame is provided with a positioning component at its upper end, which is used to clamp and position the machinery during the machining process. The positioning frame is equipped with a driving component at its lower end, which is connected to the positioning component to drive the positioning component to perform clamping or releasing actions. The positioning frame is also provided with a chip removal part at its upper end, which can push the waste generated during the machining process into the chip removal part when the positioning component performs a releasing action.

[0005] Furthermore, the positioning component includes a housing disposed below the positioning frame, the housing being detachably connected to the positioning frame by bolts, the positioning frame having multiple sliding grooves in the middle, and four of the sliding grooves being arranged in a ring, the inner cavity of the sliding groove being provided with a cylindrical rod, the upper end of the cylindrical rod being fixedly installed with a limit strip, and the inner cavity of the sliding groove being fixedly installed with a return spring.

[0006] Furthermore, one end of the return spring is fixedly connected to the inner cavity of the slide groove, and the other end of the return spring is fixedly connected to the inner side of the cylindrical rod, with the slide groove and the cylindrical rod corresponding one-to-one.

[0007] Furthermore, the lower end of the limiting strip is in contact with the upper end of the positioning frame, and the length of the limiting strip is greater than the width of the slide groove.

[0008] Furthermore, the drive assembly includes a servo motor disposed below the housing, a transmission rod is installed at the output end of the servo motor, connecting rods are welded to both sides of the transmission rod, the connecting rods are symmetrically arranged, a fixing ring is welded to the upper end of the connecting rod, and a wedge block is detachably installed on the inner side of the fixing ring, the wedge block corresponding to the cylindrical rod one by one.

[0009] Furthermore, the upper end of the transmission rod is rotatably connected to the lower middle part of the positioning frame via a bearing, and the fixing ring is located directly below the positioning frame, with the inclined surface of the wedge block fitting against the outer wall of the cylindrical rod.

[0010] Furthermore, the chip removal section includes an annular mesh plate disposed on the positioning frame. The annular mesh plate is detachably connected to the positioning frame. Collection frames are provided on both sides of the lower end of the inner cavity of the housing. The collection frames are symmetrically disposed on both sides of the servo motor, and the upper end of the collection frame covers the outer side wall of the transmission rod.

[0025] Reference Figure 1-4 A positioning device for machining mechanical equipment includes a positioning frame 11, a positioning component, a drive component, and a chip removal section. The positioning component is provided at the upper end of the positioning frame 11 and is used to clamp and position the mechanical equipment during the machining process. The drive component is assembled at the lower end of the positioning frame 11 and forms a transmission connection with the positioning component to drive the positioning component to perform clamping or loosening actions. The chip removal section is also provided at the upper end of the positioning frame 11. When the positioning component performs a loosening action, it pushes the waste material generated during the machining process into the chip removal section.

[0026] As a preferred example of this utility model, during operation, the square cabinet-shaped mechanical device to be processed is first placed in the positioning component area at the upper end of the positioning frame 11. After the drive component is started, it drives the positioning component to move through transmission, switching the positioning component from the initial state to the clamping state, forming a stable clamp on the mechanical device, limiting its displacement during processing, and ensuring processing accuracy. When the mechanical device finishes processing, the drive component moves in the opposite direction, driving the positioning component to switch from the clamping state to the loosening state, releasing the clamp on the mechanical device, and facilitating the removal of the processed workpiece. At the same time, during the loosening process of the positioning component, its movement triggers the chip removal section to operate, pushing the waste material accumulated on the surface of the positioning frame 11 during processing into the chip removal section, completing the waste material removal, and preparing for the next positioning and processing of the mechanical device.

[0027] In the example of this application, the positioning component includes a housing 1 disposed below the positioning frame 11. The housing 1 is detachably connected to the positioning frame 11 by bolts. The positioning frame 11 has a plurality of sliding grooves 14 in the middle, and the four sliding grooves 14 are arranged in a ring. A cylindrical rod 24 is provided in the inner cavity of the sliding groove 14. A limit strip 25 is fixedly installed at the upper end of the cylindrical rod 24. A return spring 27 is fixedly installed in the inner cavity of the sliding groove 14.

[0028] As a preferred example of this utility model, when the drive assembly transmits power, the annularly distributed slide groove 14 in the middle of the positioning frame 11 provides a moving track for the cylindrical rod 24. The cylindrical rod 24 can slide along the inner cavity of the slide groove 14, thereby driving the upper fixed limit strip 25 to move synchronously. When the limit strip 25 moves in the direction of clamping the mechanical device, the slide groove 14 ensures that it always moves along the preset annular trajectory to avoid deviation. When the drive assembly stops power input or reverses its action, the reset spring 27 connected to the cylindrical rod 24 in the inner cavity of the slide groove 14 releases its elastic potential energy, generates a rebound force, pushes the cylindrical rod 24 to move along the slide groove 14 to the initial position, and drives the limit strip 25 back to the detached state, reserving reset power for the next clamping action and ensuring the stable operation of the positioning assembly.

[0029] In the example of this application, one end of the return spring 27 is fixedly connected to the inner cavity of the slide groove 14, and the other end of the return spring 27 is fixedly connected to the inner side of the cylindrical rod 24. The slide groove 14 and the cylindrical rod 24 correspond one-to-one.

[0030] As a preferred example of this utility model, when the drive assembly drives the cylindrical rod 24 to move along the slide groove 14 toward the clamping mechanical device to achieve clamping, the return spring 27 is compressed and stores force; when the force of the drive assembly disappears, the return spring 27 releases its elastic force, driving the corresponding cylindrical rod 24 to slide inward along the slide groove 14, so that the cylindrical rod 24 returns to its initial position.

[0031] In the example of this application, the lower end of the limiting strip 25 is in contact with the upper end of the positioning frame 11, and the length of the limiting strip 25 is greater than the width of the slide groove 14.

[0032] As a preferred example of this utility model, when the cylindrical rod 24 slides along the groove 14, the limiting strip 25 moves simultaneously with the cylindrical rod 24. The limiting strip 25 is fitted with the positioning frame 11, which facilitates the limiting strip 25 to push the debris.

[0033] In the example of this application, the drive assembly includes a servo motor 2 disposed below the housing 1. A transmission rod 21 is installed at the output end of the servo motor 2. Connecting rods 28 are welded on both sides of the transmission rod 21. The connecting rods 28 are symmetrically arranged. A fixing ring 22 is welded to the upper end of the connecting rod 28. A wedge block 23 is detachably installed on the inner side of the fixing ring 22. The wedge block 23 corresponds one-to-one with the cylindrical rod 24.

[0034] As a preferred example of this utility model, after the servo motor 2 starts, it drives the transmission rod 21 at the output end to rotate. During the rotation of the transmission rod 21, the connecting rods 28 welded on both sides rotate synchronously, thereby driving the fixed ring 22 welded at the upper end to rotate around the axis of the transmission rod 21. The wedge block 23, which can be detachably installed on the inner side of the fixed ring 22, rotates with the fixed ring 22. Since the wedge block 23 corresponds one-to-one with the cylindrical rod 24, and the inclined surface of the wedge block 23 is in contact with the outer wall of the cylindrical rod 24, the inclined surface of the wedge block 23 will generate a radial thrust on the cylindrical rod 24 when the wedge block 23 rotates. The servo motor 2 controls the rotation speed of the transmission rod 21 by adjusting the speed, thereby controlling the magnitude and speed of the thrust of the wedge block 23 on the cylindrical rod 24, so as to meet the clamping requirements of the square cabinet mechanical equipment. When the wedge block 23 is worn, it can be directly removed and replaced from the fixed ring 22 without disassembling the entire drive assembly, reducing the maintenance difficulty.

[0035] In the example of this application, the upper end of the transmission rod 21 is rotatably connected to the lower middle part of the positioning frame 11 through a bearing, and the fixing ring 22 is located directly below the positioning frame 11, and the inclined surface of the wedge block 23 is in contact with the outer wall of the cylindrical rod 24.

[0036] As a preferred example of this utility model, the fixing ring 22 is located directly below the positioning frame 11. When it rotates with the transmission rod 21, the inclined surface of the wedge block 23 fits tightly against the outer wall of the cylindrical rod 24. The force generated by the rotation of the wedge block 23 is transmitted radially to the cylindrical rod 24 along the slide groove 14, so that the cylindrical rod 24 obtains the outer thrust, thereby achieving effective clamping of the mechanical equipment and ensuring uniform and stable clamping force.

[0037] In the example of this application, the chip removal part includes an annular mesh plate 12 disposed on the positioning frame 11. The annular mesh plate 12 is detachably connected to the positioning frame 11. Collection frames 3 are provided on both sides of the lower end of the inner cavity of the housing 1. The collection frames 3 are symmetrically disposed on both sides of the servo motor 2, and the upper end of the collection frame 3 covers the outer side wall of the transmission rod 21. The annular mesh plate 12 is disposed directly above the collection frame 3. Scraping strips 26 can be detached on both sides of the limiting strip 25, and the lower end of the scraping strip 26 is in contact with the upper surface of the positioning frame 11.

[0038] As a preferred example of this utility model, when the chip removal unit is working, some of the waste generated during the processing falls directly onto the positioning edge of the positioning frame 11, and some falls through the mesh of the annular mesh plate 12. The annular mesh plate 12 is detachably connected to the positioning frame 11. If the mesh is blocked by waste or needs to be adapted to waste of different particle sizes, the mesh plate can be removed for cleaning or replacement. The waste falling on the surface of the positioning frame 11 moves synchronously with the limit strip 25 as the cylindrical rod 24 resets during the process of the positioning component being released. The scraping strips 26 installed on both sides of the limit strip 25, because their lower ends are attached to the upper surface of the positioning frame 11, will move with the limit strip 25 to scrape the waste at the positioning edge of the positioning frame 11, pushing the waste towards the area of ​​the annular mesh plate 12. The waste falls through the mesh of the annular mesh plate 12 into the collection frame 3 symmetrically arranged below. The collection frame 3 is located on both sides of the servo motor 2 and its upper port is along the outer wall of the transmission rod 21. It can fully receive the waste falling from the annular mesh plate 12, preventing the waste from scattering into other areas inside the housing 1, and realizing the centralized collection of waste.

[0039] It is worth noting that the scraper strip 26 installed on the limit strip 25 is made of rubber, which avoids the limit strip 25 from obstructing the positioning of the square cabinet mechanical equipment.

[0040] In the example of this application, through slots 13 are provided on both sides of the lower end of the housing 1. The length of the through slots 13 is the same as the length of the collection frame 3, and the collection frame 3 is movably connected to the through slots 13.

[0041] As a preferred example of this utility model, when the waste in the collection box 3 accumulates to a certain amount, the operator can directly pull out the collection box 3 from the through groove 13, dump the waste, and then put it back in its original position through the through groove 13, which can conveniently and quickly complete the waste cleaning without affecting the normal operation of the device.

[0042] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
