[0022] Referring to Figures 1 to 5 , and Figure 9 and Figure 10 , the present application provides a universal retainer 12 processing auxiliary device, comprising: a base 4, the base 4 is connected with the reference table 6 through the connecting plate 5, the first hydraulic cylinder 7 is arranged on the base 4, the first hydraulic cylinder 7 is connected with the centering column 8 at least partially through the reference table 6, the centering column 8 is a positive prism body extending in the axial direction, the cross section is an equilateral polygon with at least three sides, and the outer dimensions continuously and uniformly decrease from top to bottom along the axial direction, a plurality of slide rails 9 are arranged on the reference table 6 and uniformly distributed in the circumferential direction along the axis of the centering column 8, the number of the slide rails 9 is the same as that of the inclined side of the centering column 8 and one-to-one correspondence, the slide blocks 10 are arranged on the slide rails 9, the transmission frame 11 is arranged on the slide blocks 10, the petal assembly 1 is arranged on the outer end side wall of the transmission frame 11, the petal assembly 1 is used for radially expanding and locking the retainer 12, the reset assembly 2 is arranged in the transmission frame 11, the pressing assembly 3 is arranged on the reference table 6, and the pressing assembly 3 is used for pressing and fixing the retainer 12.

[0023] The reset assembly 2 comprises a fixed block 201, a fixed frame 202, a connecting rod 203 and a spring 204, the fixed block 201 is arranged on the inner side wall of the transmission frame 11 close to the centering column 8, the fixed frame 202 passes through the through hole 13 of the bottom wall of the transmission frame 11 and is connected with the top surface of the reference table 6, the fixed block 201 is connected with the connecting rod 203, the rod body of the connecting rod 203 can slide in the open slot 32 of the fixed frame 202, the spring 204 is arranged between the fixed block 201 and the fixed frame 202, and the spring 204 is coaxially sleeved on the outside of the connecting rod 203.

[0024] Each set of slide rails 9 is two, and the two slide rails 9 in each set are distributed in parallel. Two sliding blocks 10 are arranged on each slide rail 9, so that the transmission frame 11 is more stable when connected to the slide rail 9 by means of the sliding block 10. A counterbore is formed at the top end of the centering column 8, and the telescopic end of the first hydraulic cylinder 7 penetrates into the counterbore from the bottom end of the centering column 8 and is fixedly connected to the centering column 8. The connecting plate 5 is multiple and is uniformly distributed in the circumferential direction along the axis of the centering column 8, so that the connection of the base 4 and the reference table 6 is more stable. The reference table 6 is provided with a hole through which the centering column 8 penetrates.

[0025] Specifically, first, the first hydraulic cylinder 7 drives the centering column 8 to move downward, and the inclined side surface of the truncated pyramid body of the centering column 8 pushes the transmission frame 11 to slide radially outward on the slide rail 9 by means of the sliding block 10, thereby driving the expansion petal assembly 1 to expand outward and lock the retainer 12. At the same time, the pressing assembly 3 presses and fixes the retainer 12. After processing is completed, the first hydraulic cylinder 7 drives the centering column 8 to move upward, and the spring 204 pushes the fixed block 201 and the connecting rod 203 to reset inward, so that the transmission frame 11 slides radially inward on the slide rail 9 by means of the sliding block 10, and the expansion petal assembly 1 is separated from the retainer 12. Through the cooperation of the pressing assembly 3 and the expansion petal assembly 1, the retainer 12 is locked in the horizontal direction, which can avoid the change of clamping force caused by vibration and other factors during processing, thereby affecting the processing quality.

[0026] Referring to Figure 7 In some embodiments, the expansion petal assembly 1 includes a support vertical plate 101, a support horizontal plate 102, and an adjusting block 103. The support vertical plate 101 is arranged on the outer end side wall of the transmission frame 11, the support horizontal plate 102 is connected to the support vertical plate 101, the support horizontal plate 102 is provided with a placing groove 15, and the adjusting block 103 is arranged in the placing groove 15.

[0027] When the transmission frame 11 moves radially, the support vertical plate 101, the support horizontal plate 102, and the adjusting block 103 move synchronously, so that the adjusting block 103 contacts and locks the inner wall of the retainer 12.

[0028] Referring to Figure 6 and Figure 8 In some embodiments, the support vertical plate 101 has a positioning block 16, the outer end side wall of the transmission frame 11 is provided with a positioning groove 17, and the positioning block 16 cooperates with the positioning groove 17 to position the support vertical plate 101 and the transmission frame 11.

[0029] During installation, the positioning block 16 of the support vertical plate 101 is inserted into the positioning groove 17 of the transmission frame 11 to achieve rapid positioning. When the transmission frame 11 moves, the positioning structure ensures that the support vertical plate 101 does not deviate.

[0030] It should be noted that the positioning groove 17 can also be arranged on the support vertical plate 101, and when the support vertical plate 101 is connected with the transmission frame 11, the positioning rod is inserted into the two positioning grooves 17 on the support vertical plate 101 and the transmission frame 11 to realize the positioning between the two, so as to facilitate the subsequent installation.

[0031] Referring to Figure 7 In some embodiments, the adjusting block 103 is connected with the support horizontal plate 102 through the fastening bolt 18 and the adjusting bolt 19, and the adjusting block 103 is detachably arranged with the adjusting piece 20 between the support horizontal plate 102 and the adjusting block 103. The fastening bolt 18 fixes the support horizontal plate 102 and the adjusting block 103 in the horizontal direction, and the adjusting bolt 19 fixes the support horizontal plate 102 and the adjusting block 103 in the vertical direction by passing through the nut groove 21.

[0032] The precision of the placing groove 15 is preferably 0.05 mm, the adjusting block is located in the placing groove 15, the fastening bolt 18 and the adjusting bolt 19 are screwed to preliminarily position, and are not locked at this time. At this time, the adjusting block 103 can move towards the center or outward in the horizontal direction, the adjusting piece is arranged between the adjusting block and the vertical plane of the support horizontal plate 102 towards the center, and then the fastening bolt 18 and the adjusting bolt 19 are synchronously and alternately locked to fix the adjusting block 103 and the support horizontal plate 102.

[0033] Referring to Figure 2 In some embodiments, the pressing assembly 3 includes a support table 301, a second hydraulic cylinder 302, a pressing cover 303 and a first nut 304. The reference table 6 is provided with the support table 301 corresponding to the sliding rail 9 one by one, the support table 301 is connected with the second hydraulic cylinder 302 through the avoiding hole 22 on the support horizontal plate 102, the telescopic end of the second hydraulic cylinder 302 is provided with external threads, and the telescopic end of the second hydraulic cylinder 302 is screwed with the first nut 304 through the pressing groove 14 on the pressing cover 303.

[0034] The support table 301 is preferably adjusted in the manner of pin hole cooperation, that is, the support table 301 includes a support top end and a support bottom end, both of which have pin holes and are connected through a pin shaft. The second hydraulic cylinder 302 drives the telescopic end to press down, driving the pressing cover 303 to press the top of the retainer 12.

[0035] It should be noted that the avoiding hole 22 needs to allow the support table 301 to pass freely, and the hole diameter size of the avoiding hole 22 is greater than the size of the vertical direction section of the support table 301, so that when the adjusting block 103 expands or contracts radially along the length direction of the guide rail, the support horizontal plate 102 will not conflict with the support table 301. The pin hole lifting structure of the support table 301 is a technology known to those skilled in the art, and the present application does not improve it, so it is not described here.

[0036] Preferably, the first hydraulic cylinder 7 and the second hydraulic cylinder 302 are connected with the hydraulic station 31 through hydraulic pipelines respectively. The first hydraulic cylinder 7 and the second hydraulic cylinder 302 are controlled by the hydraulic station 31 to keep the cage 12 in tension and compression. When the hydraulic station 31 is closed, the pressure can be maintained for at least two hundred hours to ensure the continuous effect of the tension and compression. At the same time, the tension and compression of the cage 12 in each position and each time are effectively ensured to be constant. Further, a pressure sensor can be additionally arranged on the first hydraulic cylinder 7 and the second hydraulic cylinder 302 to monitor the output pressure of the first hydraulic cylinder 7 and the second hydraulic cylinder 302 in real time, and the pressure is automatically adjusted through the control system to ensure the precise control of the clamping force.

[0037] It should be noted that the specific structure of the hydraulic station 31, the detection of the output pressure of the first hydraulic cylinder 7 and the second hydraulic cylinder 302 by the pressure sensor, and the control through the control system are known to those skilled in the art, and the application does not improve them, so they are not described in detail here.

[0038] Referring to Figure 3 In some embodiments, the grommet 303 is provided with a protrusion 23, and the bottom end of the protrusion 23 is provided with a limiting groove 24 for clamping the cage 12.

[0039] Specifically, when the grommet 303 is pressed down, the limiting groove 24 of the protrusion 23 is clamped into the edge of the cage 12 to prevent horizontal movement, and the hydraulic cylinder continues to press down to realize compression. The shape of the limiting groove 24 needs to match the cage 12 to avoid stress concentration when the two are in contact.

[0040] Referring to Figure 11 In some embodiments, the end of the connecting rod 203 away from the fixed block 201 is provided with an external thread, and a sleeve 25 is screwed thereon, and the sleeve 25 is provided with a second nut 26, and the sleeve 25 can slide in the open groove 32.

[0041] The sleeve 25 at the end of the connecting rod 203 slides in the open groove 32 of the fixed frame 202, and the pre-tightening force of the spring 204 is adjusted by rotating the second nut 26 to change the position of the sleeve 25 on the connecting rod 203. The spring 204 moves to pull the fixed block 201 back to its original position.

[0042] Referring to Figure 2 , Figure 4 and Figure 5 In some embodiments, the bottom surface of the bottom end of the first hydraulic cylinder 7 is provided with a reference circular table 27, and the reference circular table 27 is provided with a guide frame 28, and the centering column 8 moves on the guide frame 28.

[0043] The guide frame 28 comprises a lower circular ring, guide columns and an upper circular ring. The four guide columns are preferably parallel to each other with a parallelism of 0.05 mm, and perpendicular to the reference table 6 with a perpendicularity of 0.05 mm. The four guide columns are evenly arranged on the lower circular ring in a circumferential direction, and the upper ends of the guide columns are connected to the upper circular ring. A sliding block is sleeved on each guide column. The centering column 8 is provided with guide holes corresponding to the guide columns. The sliding blocks are fixed in the guide holes. The guide frame 28 is slidably connected to the centering column 8. When the centering column 8 is driven by the first hydraulic cylinder 7, the centering column 8 moves axially along the guide columns to ensure that the accuracy is close to 0.05 mm. When it is necessary to fix the first hydraulic cylinder 7, the lower circular ring on the reference table can be used for positioning.

[0044] The first hydraulic cylinder 7 drives the centering column 8 to move up and down through the reference circular table 27 and the guide frame 28, thereby reducing the deflection. The centering column 8 slides along the guide frame 28 to push the transmission frame 11. The guide frame 28 is parallel to the axis of the centering column 8. The reference circular table 27 is horizontally arranged and connected to the base 4.

[0045] In some embodiments, a transition block 29 is arranged on the inner end outer side wall of the transmission frame 11. The transition block 29 is made of wear-resistant material, preferably alumina ceramic or high manganese steel, etc. When the centering column 8 moves axially under the action of the first hydraulic cylinder 7, it extrudes the transition block 29 outward, and in turn drives the transmission frame 11 to move radially outward on the slide rail 9 through the sliding block 10.

[0046] Specifically, the transition block 29 at the inner end of the transmission frame 11 is in contact with the inclined surface of the centering column 8 to reduce friction. When the centering column 8 moves, the transition block 29 slides along the inclined surface to drive the transmission frame 11 to move radially.

[0047] Referring to Figure 6 and Figure 8 In some embodiments, elastic sealing rubber 30 is arranged between the top surfaces of any two adjacent transmission frames 11 and between the outer side surfaces of any two adjacent support vertical plates 101.

[0048] The top of the transmission frame 11 is provided with a cover plate, and the gap between the cover plates is connected by elastic sealing rubber 30. The outer side surface of the support vertical plate 101 is provided with a scraper, which is used to scrape off the iron filings falling on the reference table 6. The scraper is preferably a 5 mm thick polyurethane plate. The cooperation of the cover plate and the scraper effectively prevents the iron filings inside the device from being contaminated. The elastic sealing rubber 30 fills the gap between the adjacent transmission frames 11 and the support vertical plates 101, preventing dust and buffering vibration. When the transmission frame 11 moves, the rubber deforms but does not interfere with the movement, and does not affect the freedom of movement of the transmission frame 11.

[0049] Working process First, according to the specifications of the retainer 12, adjust the height of the support table 301, loosen the first nut 304, remove the gland 303 from the second hydraulic cylinder 302, place the retainer 12 on the reference table 6 without centering or rough centering, and frame the retainer 12 with the plurality of adjustment blocks 103. Then, insert the plurality of pressing grooves 14 on the gland 303 into the plurality of second hydraulic cylinder 302 extension ends one by one, tighten the first nut 304, and fix the gland 303 on the extension end of the second hydraulic cylinder 302.

[0050] Then, control the first hydraulic cylinder 7 and the second hydraulic cylinder 302 to start by the hydraulic station 31, the extension end of the first hydraulic cylinder 7 drives the centering column 8 to move downward along the guide frame 28, the positive prism slope of the centering column 8 synchronously pushes the transition block 29 on the outer wall of the inner end of each transmission frame 11, the sliding block 10 slides radially outward along the sliding rail 9, thereby driving the transmission frame 11 and the support vertical plate 101, support horizontal plate 102 and adjustment block 103 at the outer end of the transmission frame 11 to expand radially outward; the adjustment block 103 tightly pushes the inner wall of the retainer 12 to achieve centering and locking; At the same time, the fixed block 201 compresses the spring 204, and the fixed frame 202 guides the movement of the connecting rod 203 through the open slot 32; the extension end of the second hydraulic cylinder 302 retracts, causing the gland 303 to move downward, and the protrusion 23 and the limiting groove 24 of the gland 303 to press and clamp the top of the retainer 12 to complete the compression; Finally, the second hydraulic cylinder 302 extends to release the compression of the retainer 12 by the gland 303, the first hydraulic cylinder 7 drives the centering column 8 to move upward, the reset spring 204 releases the elastic force, the fixed block 201 and the transmission frame 11 retract, the adjustment block 103 disengages from the retainer 12, and each component returns to the initial state; During the entire process, the elastic sealing rubber 30 is always filled between adjacent transmission frames 11 and support vertical plates 101 to play a sealing and buffering role.

[0051] The application adopts a hydraulic drive and mechanical transmission structure, which precisely controls the linear displacement of the centering column 8 by executing the downward pulling or upward moving action of the first hydraulic cylinder 7. The linear displacement of the cover plate is precisely controlled by the downward pulling or upward moving action of the first hydraulic cylinder 7, and the retainer 12 is fixed by the horizontal and vertical forces. The centering column 8 triggers the radial expansion of the transmission frame 11, and then drives the adjustment block 103 to form a uniform and adjustable ring-shaped tension field.

[0052] The technical scheme of the present application can dynamically adjust the tensioning degree and range according to different specifications of the retainer 12, effectively overcoming the defects of the traditional device, such as single specification, insufficient clamping precision, etc. The device has compact structure and high degree of functional integration, and the operation process is intelligently controlled, which can seamlessly adapt to various processing process scenes. With its stable and reliable supporting performance and excellent compatibility, the device not only significantly improves the production efficiency and product precision of the retainer 12 processing, but also promotes the retainer 12 processing field to the intelligent and flexible direction, and has high industrial application value and technical foresight.
