Description

Technical Field

[0001] The invention belongs to the technical field of calibrating parts in holes, and in particular relates to a high-precision positioning rotary table with a gapless worm drive. Background Art

[0002] The rotary table is an ideal accessory for all kinds of CNC milling machines and machining centers. It is installed horizontally on the work surface of the host machine. When working, it uses the control system of the host machine or a specially matched control system to complete the indexing rotary motion of various processing coordinated with the host machine. For some small and medium-sized parts, multiple processes can be processed in the same clamping, and the productivity of the machine tool is improved. The rotary table is an important accessory for boring machines, drilling machines, milling machines, and slotting machines. It is used to process holes, grooves and inclined surfaces with indexing requirements. When the worktable is rotated during processing, arc surfaces and arc grooves can be processed. According to different structures, the general rotary table is divided into horizontal rotary table, vertical and horizontal rotary table and universal rotary table.

[0003] Citation: Chinese patent application number is 2022115402810, which specifically discloses a multi-station rotary combined machine tool, including a base, the base is connected to a plurality of fixed stations, the fixed stations are fixed on the periphery of the base and arranged around the circumference of the base, the base is fixedly connected to a central rotating table, the end of the central rotating table away from the base is connected to a plurality of clamping chucks, and the central rotating table can rotate to drive the clamping chucks to each fixed station. The processing head on each fixed station is fixed and unchanged, and the workpiece that has completed the previous process is transferred to the next fixed station for processing by rotating the central rotating table. Different processing processes are superimposed, which greatly improves the work efficiency of each station. Since the position of the fixed station remains unchanged, the position between each clamping chuck is relatively static and unchanged, so the centering correction of the central rotating table after each rotation can synchronously realize the centering correction of all the clamping chucks connected thereto, greatly improving the efficiency of the overall processing production.

[0004] Citation: Chinese patent application number is 2019108193984, which discloses a machine tool for processing the external convex of an expansion tube, including a frame and a guide rail arranged on the frame, a synchronous mold and a fixture are arranged on the guide rail, the synchronous mold is arranged at both ends of the fixture, the fixture is used to clamp the workpiece and rotate the workpiece, and an extrusion device for simultaneously processing the external convex at both ends of the workpiece is arranged between the fixture and the synchronous mold. The present invention performs consistent processing on both ends of the workpiece at the same time, detects and corrects the workpiece before processing, and the workpiece can always rotate on the same axis, which effectively ensures the consistency of uniform force processing at both ends of the workpiece, and simultaneously rotates and extrude the processing end of the workpiece, and the thickness of the end of the workpiece increases more evenly, which is convenient for improving the processing accuracy and the structural strength of the workpiece, and is convenient for improving the connection strength and sealing effect between the external convex of the expansion tube and the external connector.

[0005] However, when the worktable of the above-mentioned existing machine tool rotates, it is difficult for the parts to be processed to be aligned with the placement holes and slots of the worktable, and it is difficult for the parts to be centered. Most of the parts are placed in the placement holes and slots on the worktable by a manipulator or a clamping structure, and the parts themselves do not have the centering calibration function. Once the part is offset in the placement hole and slot and is not in the centered state, after the worktable rotates, an additional step will be added to calibrate the center of the part. The position of the part is adjusted by additional machinery or manual centering, which makes the overall processing of the parts by the machine tool relatively complicated and cumbersome, and the processing operation of the machine tool is not consistent. The worktable is rotated by the worm. When the worm stops running, the worm and the worktable will rotate to a certain extent. This is because the worm transmission is not accurate and will be affected by certain inertia, gravity and other factors. It is difficult to stop immediately and often rotates at a small angle, making the rotary table less efficient. It often needs to wait for it to stop automatically or for manual intervention by the staff, which is not conducive to the use of the machine tool. At the same time, the rotary table does not have the function of clamping parts, but only plays the role of bearing and supporting the parts. Once the parts have other shapes, such as the center of gravity is forward and the volume is small, the parts are only placed on the rotary table and it is easy to fall off the table. For this reason, we propose a high-precision positioning rotary table with gapless worm drive. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention can correct and center the part inserted into the part insertion hole slot. When the part is placed on the workbench base and the part is inserted into the hole slot, the part can be corrected by the integrated drive assembly, so that the part is always in the part insertion hole slot and in the center position, reducing the manual correction by the staff, or the additional steps and mechanical correction, which effectively saves time. At the same time, the integrated drive assembly also has a clamping effect. When the part is inserted into the part insertion hole slot, the integrated drive assembly will simultaneously correct and clamp the part insertion hole slot. The batch operation makes the correction, insertion and removal of the parts more convenient.

[0018] The precision positioning component can be used to reduce the situation where the anti-slip outer shell rotates on its own. When the anti-slip outer shell rotates, the recognition camera can identify the precision identification mark to make the rotation operation more accurate and reduce errors and offsets. At the same time, when the anti-slip outer shell completes the rotation operation, the telescopic rod will drive the linkage bottom plate to move down, so that the reinforced bottom pattern is in close contact with the reinforced pattern ring. The linkage bottom plate continuously applies downward pressure on the reinforced pattern ring, and the friction between the reinforced bottom pattern and the reinforced pattern ring is relatively high, so the anti-slip outer shell can be fixed, reducing the small-angle rotation of the anti-slip outer shell due to worm gear transmission, low accuracy, and manual intervention by staff.

[0019] The integrated drive assembly is located inside the anti-slip outer shell, and each pair of first correction clamping plates and second correction clamping plates are placed in the calibration clamping placement groove and are symmetrically arranged. When the part is inserted into the hole groove, a pair of first correction clamping plates and second correction clamping plates will move in opposite directions at the same time, thereby correcting and clamping the part inserted into the hole groove. Multiple second correction clamping plates are fixed on the first linkage ring, and multiple first correction clamping plates are fixed on the second linkage ring. With the rotation of the second linkage ring and the first linkage ring, multiple first correction clamping plates and second correction clamping plates can be fixed or separated at the same time, and are more flexible when used.

[0020] The cross-section of the first correction clamping plate and the second correction clamping plate can be a rectangle or a right-angled trapezoid, and the length of the first correction clamping plate and the second correction clamping plate is less than the length of the calibration clamping placement slot, so that when the first correction clamping plate and the second correction clamping plate change their displacement, the calibration clamping placement slot will not be blocked, leaving sufficient displacement space. At the same time, when the cross-section of the first correction clamping plate and the second correction clamping plate is a right-angled trapezoid, the distance between the two is smaller after displacement, so that some parts with special shapes or smaller volumes can be corrected and clamped.

[0021] The first linkage ring and the second linkage ring are rotatably connected, and the two are connected to each other by limiting concave rings and limiting snap rings, and the first linkage ring and the second linkage ring are driven in the same way, and are driven to rotate by the second locking drive motor and the first locking drive motor respectively, so that the driving cost of the first correction clamping plate and the second correction clamping plate is low, and there is no need to equip each first correction clamping plate and the second correction clamping plate with a moving structure as required in the prior art, which greatly reduces the cost and is more convenient and quick to use, and multiple first correction clamping plates and second correction clamping plates can be operated at the same time.

[0022] The overall use of the present invention is relatively consistent, which greatly reduces the manual participation of staff, and is very consistent in use. The precision positioning component can achieve the effect of high-precision identification and precise fixation. After the precision positioning component has completed the identification, the integrated driving component can be used to calibrate and clamp the parts inserted into the insertion hole groove, and multiple parts can be calibrated and clamped at the same time, which is highly efficient, has a low structural cost, and is more convenient to use.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figures 1 to 12 The present invention provides a technical solution: a high-precision positioning rotary table with a gapless worm drive, comprising a machine tool body 100, a machine tool built-in base 103 is provided in the middle of the machine tool body 100, observation windows 101 are movably provided on both sides of the machine tool body 100, and also includes: The workbench base 200 is arranged on the top of the built-in base 103 of the machine tool; The workbench body 400 is disposed directly above the workbench base 200, and the workbench body 400 is a cylindrical structure; The integrated driving assembly 500 is disposed inside the workbench body 400 and is used to calibrate the parts on the workbench body 400; The precision positioning assembly 600 is disposed on the outer side wall of the workbench body 400 and is used to accurately identify and limit the rotation of the workbench body 400 .

[0026] The present invention can correct and center the part inserted into the part insertion slot 403. When the part is placed on the workbench base 200 and the part is inserted into the slot 403, the part can be corrected by the integrated drive assembly 500, so that the part is always in the part insertion slot 403 and centered, reducing manual correction by staff, or additional steps and mechanical correction, effectively saving time. At the same time, the integrated drive assembly 500 also has a clamping effect. When the part is inserted into the part insertion slot 403, the integrated drive assembly 500 will simultaneously correct and clamp the part insertion slot 403. Batch operation makes the correction, insertion and removal of parts more convenient.

[0027] In this embodiment, preferably, Figure 2 , Figure 3 , Figure 4 The workbench body 400 includes an anti-slip outer shell 402, which is arranged on the top of the workbench base 200. A plurality of parts insertion holes 403 are provided around the top of the anti-slip outer shell 402. Calibration clamping grooves 404 are provided on the inner walls on both sides of the parts insertion holes 403. A built-in bearing 405 is provided in the middle of the top of the anti-slip outer shell 402, and a plurality of protective patterns 406 are provided on the top wall of the anti-slip outer shell 402.

[0028] The parts to be processed by the machine tool can be inserted and placed in the part insertion slot 403, and the position of the calibration clamp placement slot 404 can be referred to. Figure 3 , the inserted part is exactly located between the two calibration clamping placement grooves 404.

[0029] In this embodiment, preferably, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 The integrated driving assembly 500 is located in the anti-slip outer shell 402, and the integrated driving assembly 500 includes a second linkage ring 503 and a first linkage ring 504, the second linkage ring 503 is provided with a plurality of first correction clamping plates 501, the first linkage ring 504 is provided with a plurality of second correction clamping plates 502, and the plurality of first correction clamping plates 501 and the second correction clamping plates 502 are respectively located in the calibration clamping placement groove 404.

[0030] The integrated drive assembly 500 is located inside the anti-slip outer shell 402, and each pair of first correction clamping plates 501 and second correction clamping plates 502 are placed in the calibration clamping placement groove 404 and are symmetrically arranged. When the part is inserted into the hole groove 403, a pair of first correction clamping plates 501 and second correction clamping plates 502 will move in opposite directions at the same time, thereby correcting and clamping the part inserted into the hole groove 403. Multiple second correction clamping plates 502 are fixed on the first linkage ring 504, and multiple first correction clamping plates 501 are fixed on the second linkage ring 503. With the rotation of the second linkage ring 503 and the first linkage ring 504, multiple first correction clamping plates 501 and second correction clamping plates 502 can be fixed or separated at the same time, and are more flexible when used.

[0031] When it is necessary to correct the part inserted into the part insertion hole slot 403, the displacement of the first correction clamping plate 501 and the second correction clamping plate 502 can be changed so that the two first correction clamping plates 501 and the second correction clamping plates 502 move in opposite directions at the same time, thereby correcting the part to the center of the part insertion hole slot 403.

[0032] Furthermore, a plurality of first correction clamping plates 501 and second correction clamping plates 502 can be operated simultaneously, which means that a plurality of parts can be corrected, centered and fixed simultaneously.

[0033] In this embodiment, preferably, Figure 7 A limiting snap ring 511 is provided at the bottom of the first linkage ring 504 , a limiting concave ring 512 is provided at the top of the second linkage ring 503 , and the first linkage ring 504 and the second linkage ring 503 are rotatably connected through the limiting snap ring 511 and the limiting concave ring 512 .

[0034] The first linkage ring 504 and the second linkage ring 503 are rotationally connected, and the relative rotation angle between the two is less than sixty degrees. When the first linkage ring 504 and the second linkage ring 503 rotate, they will respectively drive multiple second correction clamping plates 502 and the first correction clamping plate 501 to change their displacement, and the relative movement distance of the first correction clamping plate 501 and the second correction clamping plate 502 is small, so the relative rotation angle between the second linkage ring 503 and the first linkage ring 504 is also very small.

[0035] At the same time, since the second correction clamping plate 502 and the first correction clamping plate 501 change their displacement by rotating the first linkage ring 504 and the second linkage ring 503, the trajectory of the second correction clamping plate 502 and the first correction clamping plate 501 changing their displacement is also arc-shaped. Fig. 9In the embodiment, the first calibration clamping plate 501 and the second calibration clamping plate 502 are parallel to each other at a predetermined angle. When the part needs to be calibrated, the first calibration clamping plate 501 and the second calibration clamping plate 502 are just at the same angle. Fig. 9 At the same time, the cross-sections of the first correction clamping plate 501 and the second correction clamping plate 502 can also be right-angled trapezoids, so that the distance between the two is smaller after displacement, and some parts with special shapes or small volumes can be corrected and clamped.

[0036] The first linkage ring 504 and the second linkage ring 503 are rotatably connected, and both are connected to each other by limiting the concave ring 512 and the limiting snap ring 511, and the first linkage ring 504 and the second linkage ring 503 are driven in the same way, and are driven to rotate by the second locking drive motor 508 and the first locking drive motor 510 respectively, so that the driving cost of the first correction clamping plate 501 and the second correction clamping plate 502 is low, and there is no need to equip each first correction clamping plate 501 and the second correction clamping plate 502 with a moving structure as required in the prior art, which greatly reduces the cost and is more convenient and quick to use, and multiple first correction clamping plates 501 and second correction clamping plates 502 can be operated simultaneously.

[0037] In this embodiment, preferably, Figure 4 , Figure 5 , Figure 6 , Figure 7 A second locking drive motor 508 is provided on one side of the second linkage ring 503, a second drive gear 505 is provided in the output shaft direction of the second locking drive motor 508, a second drive gear column group 507 is provided on the side wall of the second linkage ring 503, and the second drive gear column group 507 is meshed and connected with the second drive gear 505; A first locking drive motor 510 is disposed on one side of the first linkage ring 504 , a first drive gear 506 is disposed on the output shaft direction of the first locking drive motor 510 , a first drive gear column group 509 is disposed on the side wall of the first linkage ring 504 , and the first drive gear column group 509 is meshedly connected with the first drive gear 506 .

[0038] The first linkage ring 504 and the second linkage ring 503 have the same rotation principle. After the first locking drive motor 510 is running, the first drive gear 506 and the first drive gear column group 509 are meshed and connected, so that the first linkage ring 504 rotates; while the second linkage ring 503 is running after the second locking drive motor 508 is running, and the second drive gear 505 and the second drive gear column group 507 are meshed and connected, so that the second linkage ring 503 rotates. However, the second linkage ring 503 and the first linkage ring 504 rotate in opposite directions. When the second linkage ring 503 rotates clockwise, the first linkage ring 504 rotates counterclockwise; when the second linkage ring 503 rotates counterclockwise, the first linkage ring 504 rotates clockwise. In addition, the second linkage ring 503 and the first linkage ring 504 have the same rotation angle and the same rotation time.

[0039] In this embodiment, preferably, Figure 4 , Figure 5 , Figure 6 , Figure 7 , the top walls of the first correction clamping plate 501 and the second correction clamping plate 502 are in the same plane, and a gap is provided between the first correction clamping plate 501 and the second correction clamping plate 502, and each time the first correction clamping plate 501 and the second correction clamping plate 502 move simultaneously and in opposite directions, the moving distance of the first correction clamping plate 501 and the second correction clamping plate 502 is less than the width of the part insertion hole slot 403; The number of each pair of first correction clamping plates 501 and second correction clamping plates 502 is consistent with the number of the part insertion slots 403 .

[0040] After the parts are inserted into the hole groove 403, they can be corrected, clamped and centered by the first correction clamping plate 501 and the second correction clamping plate 502. At the same time, when the second linkage ring 503 and the first linkage ring 504 rotate, multiple first correction clamping plates 501 and second correction clamping plates 502 can change their displacement at the same time, so that multiple parts can be corrected, clamped and centered at the same time, which is very labor-saving and convenient.

[0041] In this embodiment, preferably, Figure 2 , Figure 3 , Fig.10 , Fig.11 , Fig.12 A high-precision identification device 401 is provided on the outer wall of the anti-slip outer shell 402, and a precision positioning component 600 is provided on the high-precision identification device 401. The precision positioning component 600 includes a protective outer shell 601, and an identification camera 605 is provided at the bottom of the protective outer shell 601. A plurality of precision identification marks 408 are provided on the top of the workbench base 200, and the precision identification marks 408 are used in conjunction with the identification camera 605.

[0042] The precision positioning component 600 can reduce the self-rotation of the anti-skid outer shell 402. When the anti-skid outer shell 402 rotates, the recognition camera 605 can identify the precision recognition mark 408 to make the rotation operation more accurate and reduce errors and offsets.

[0043] In this embodiment, preferably, Figure 2 , Figure 3 , Fig.10 , Fig.11 , Fig.12 A linkage base plate 603 is connected to the high-precision identification device 401 through a telescopic rod 602, and a reinforcing pattern 604 is provided at the bottom of the linkage base plate 603. The top of the workbench base 200 is located at the anti-slip outer shell 402 and is surrounded by a reinforcing pattern ring 407 with an annular structure. The reinforcing pattern ring 407 is used in conjunction with the reinforcing pattern 604, and the width of the reinforcing pattern ring 407 is greater than the width of the reinforcing pattern 604.

[0044] The linkage base plate 603 can be adjusted up and down in height through the telescopic rod 602. When the anti-slip outer shell 402 receives a stop operation command and the identification camera 605 identifies the precision identification mark 408, the linkage base plate 603 will move downward through the telescopic rod 602, so that the reinforced bottom pattern 604 is in close contact with the reinforced pattern ring 407. The linkage base plate 603 continuously applies downward pressure to the reinforced pattern ring 407, and the friction between the reinforced bottom pattern 604 and the reinforced pattern ring 407 is relatively high, so the anti-slip outer shell 402 can be fixed, reducing the anti-slip outer shell 402 from small-angle rotation due to worm gear transmission, low precision, and manual intervention by staff.

[0045] In this embodiment, preferably, the angle between two adjacent precision identification marks 408 is sixty degrees, and the length of the precision identification mark 408 is greater than the width of the protective shell 601 .

[0046] The number of precision identification marks 408 corresponds to the part insertion hole groove 403. When the worm gear transmission 300 and the anti-slip outer shell 402 stop running, the identification camera 605 can identify the existence of the precision identification mark 408, and the linkage bottom plate 603 will continuously apply downward pressure to the reinforcement pattern ring 407. The friction between the reinforcement bottom pattern 604 and the reinforcement pattern ring 407 is relatively high, so the anti-slip outer shell 402 can be fixed, thereby achieving the effect of high precision and accurate positioning.

[0047] In this embodiment, preferably, Figure 1 , Figure 2 An operation panel 102 is provided on the side wall of the machine tool body 100 , guard plates 201 are provided on both sides of the workbench base 200 , a worm gear 300 is provided on one side of the workbench base 200 , and the anti-slip outer shell 402 is rotated by the drive of the worm gear 300 .

[0048] Working principle and usage process: After the part is inserted into the part insertion slot 403, the second locking drive motor 508 and the first locking drive motor 510 can be operated at the same time. After the first locking drive motor 510 is operated, the first drive gear 506 and the first drive gear column group 509 are meshed and connected, so that the first linkage ring 504 rotates; and the second linkage ring 503 is rotated by the second locking drive motor 508 operating, and the second drive gear 505 and the second drive gear column group 507 are meshed and connected. However, the second linkage ring 503 and the first linkage ring 504 have opposite rotation directions. When the second linkage ring 503 rotates clockwise, the first linkage ring 504 rotates counterclockwise; when the second linkage ring 503 rotates counterclockwise, the first linkage ring 504 rotates clockwise. And the second linkage ring 503 and the first linkage ring 504 have the same rotation angle and the same rotation time; When the second linkage ring 503 and the first linkage ring 504 rotate simultaneously, the plurality of second correction clamping plates 502 located on the top of the first linkage ring 504 and the plurality of first correction clamping plates 501 located on the top of the second linkage ring 503 will also change their displacements simultaneously. The plurality of second correction clamping plates 502 and the first correction clamping plates 501 clamp, center and calibrate the parts in the parts insertion hole slot 403 through the calibrated clamping placement slot 404, so that the parts are located in the middle of the parts insertion hole slot 403 and can play a clamping role at the same time. The cross-sections of the first correction clamping plate 501 and the second correction clamping plate 502 can be rectangular or right-angled trapezoidal, and the lengths of the first correction clamping plate 501 and the second correction clamping plate 502 are less than the length of the calibration clamping placement slot 404, so that when the first correction clamping plate 501 and the second correction clamping plate 502 change their displacement, the calibration clamping placement slot 404 will not be blocked, leaving enough displacement space. At the same time, when the cross-sections of the first correction clamping plate 501 and the second correction clamping plate 502 are right-angled trapezoidal, the distance between the two is smaller after displacement, so that some parts with special shapes or small volumes can be corrected and clamped; The precision positioning component 600 can reduce the situation where the anti-skid outer shell 402 rotates on its own. When the anti-skid outer shell 402 rotates, the identification camera 605 can identify the precision identification mark 408 to make the rotation operation more accurate and reduce errors and offsets. The linkage base plate 603 can adjust the height up and down through the telescopic rod 602. When the anti-skid outer shell 402 receives a stop operation command and the identification camera 605 identifies the precision identification mark 408, the linkage base plate 603 will move downward through the telescopic rod 602, so that the reinforced bottom pattern 604 is in close contact with the reinforced pattern ring 407. The linkage base plate 603 continuously applies downward pressure to the reinforced pattern ring 407, and the friction between the reinforced bottom pattern 604 and the reinforced pattern ring 407 is relatively high, so the anti-skid outer shell 402 can be fixed, reducing the small-angle rotation of the anti-skid outer shell 402 due to the worm gear transmission, low precision, manual intervention by staff, etc., thereby achieving high precision and accurate positioning.
