DETAILED DESCRIPTION

[0027] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The following describes the ring gear drilling and positioning device according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0029] like Figure 1 、 Figure 7 and Figure 8 As shown, the gear ring drilling and positioning device according to the embodiment of the present invention may include a liquid collecting tank 100 , a table 200 , a turntable 300 , a clamping structure 400 and a locking structure 500 .

[0030] The table 200 is arranged in the liquid collecting tank 100, and the turntable 300 is rotatably arranged on the table 200. Figure 5As shown, a protrusion 301 is provided at the center of the turntable 300, the outer wall of the protrusion 301 matches the inner wall of the shaft sleeve 601 of the ring gear 600, a threaded hole 302 is opened on the protrusion 301, and multiple pin holes 303 are opened at equal angles on the side of the turntable 300.

[0031] The shaft sleeve 601 of the gear ring 600 is sleeved on the protrusion 301 , and the clamping structure 400 is threadedly connected to the threaded hole 302 to clamp the gear ring 600 .

[0032] It should be noted that the height of the protrusion 301 is smaller than the length of the sleeve 601. In addition, since the inner wall of the sleeve 601 matches the outer wall of the protrusion 301, the ring gear 600 can be mounted on the protrusion 301 to achieve precise initial positioning, and then the ring gear 600 is locked by the clamping structure 400 to achieve final positioning.

[0033] The locking structure 500 is set on the table 200, and the locking end of the locking structure 500 is inserted into the pin hole 303 to limit the rotation of the turntable 300. The drilling machine 700 is set next to the liquid collection tank 100, and the working end of the drilling machine 700 is eccentrically set above the turntable 300.

[0034] It should be noted that the gear ring 600 usually needs to be provided with multiple openings on the same ring, and the number of the pin holes 303 can be synchronously set according to the number of drilled holes in the gear ring 600.

[0035] For example, if three holes need to be drilled at equal angles on the gear ring 600, then three pin holes 303 can also be opened at equal angles on the side of the turntable 300. The relevant staff can limit the three pin holes 303 in sequence through the locking structure 500 to realize the operation of drilling three holes on the gear ring 600.

[0036] Specifically, when the relevant staff needs to drill a hole in the ring gear 600, first, the relevant staff puts the sleeve 601 of the ring gear 600 on the protrusion 301, and then fixes the ring gear 600 on the turntable 300 through the clamping structure 400. Then the relevant staff rotates the turntable 300 so that the locking end of the locking structure 500 is inserted into one of the pin holes 303.

[0037] Then the relevant staff controls the drilling machine 700 to drill the gear ring 600. After the drilling is completed, the relevant staff pulls out the locking end of the locking structure 500 from the pin hole 303, and rotates the turntable 300 to insert the locking end of the locking structure 500 into the next pin hole 303, and continues the drilling operation, and so on.

[0038] In one embodiment of the present invention, Figure 3 and Figure 4As shown, the clamping structure 400 includes a screw 410 , a pressure plate 420 and a washer 430 .

[0039] The pressure plate 420 is provided with a through hole, and the pressure plate 420 is pressed tightly into the gear ring 600 . The screw 410 passes through the through hole on the pressure plate 420 and is threadedly connected to the threaded hole 302 . The gasket 430 is arranged between the pressure plate 420 and the end of the screw 410 .

[0040] In order to prevent the pressure plate 420 from damaging the ring gear 600 when pressing the ring gear 600 , a rubber anti-skid pad is provided on a side of the pressure plate 420 close to the ring gear 600 .

[0041] It should be noted that when the relevant staff positions the ring gear 600, they first put the sleeve 601 on the raised portion 301, and then pass the gasket 430 and the pressure plate 420 through the screw 410 in turn, and then use a labor-saving wrench or an electric wrench to thread the screw 410 into the threaded hole 302. At this time, since the sleeve 601 is put on the raised portion 301, it is limited by the raised portion 301 and is also tightened by the pressure plate 420, so that the fixation of the ring gear is more stable.

[0042] In one embodiment of the present invention, Figure 2 and Figure 6 As shown, the locking structure 500 includes a U-shaped frame 510 , a latch 520 , a baffle 530 and a spring 540 .

[0043] The U-shaped frame 510 is set on the table 200, the pin 520 can move through both sides of the U-shaped frame 510, the baffle 530 is set between the U-shaped frames 510 and fixed on the pin 520, the spring 540 is sleeved on the pin 520, and the two ends of the spring 540 are respectively connected to the baffle 530 and the U-shaped frame 510 on the side away from the turntable 300, wherein the pin 520 matches the pin hole 303.

[0044] It should be noted that when the locking end of the locking structure 500 is inserted into the pin hole 303, the relevant staff can pull the pin 520 outward so that the pin 520 drives the baffle 530 to move, and the spring 540 is squeezed. When the pin hole 303 on the turntable 300 rotates to the position of the pin 520, the relevant staff can let go, and the pin 520 pushes the baffle 530 and the pin 520 to move under the resetting action of the spring 540, so that the baffle 530 abuts against the U-shaped frame 510, and the pin 520 is inserted into the pin hole 303.

[0045] In order to facilitate relevant staff to pull the latch 520, a handle 522 is provided at one end of the latch 520 away from the turntable 300.

[0046] As a possible scenario, a limiting column 501 is provided on the U-shaped frame 510 , and a blocking block 521 is provided on the latch 520 . When the latch 520 is reset to the pin hole 303 by the spring 540 , the blocking block 521 abuts against the limiting column 501 .

[0047] The relevant staff can then pull the latch 520 and rotate the latch 520 so that when the latch 520 is reset by the action of the spring 540, the blocking block 521 abuts against the limiting column 501. At this time, the latch 520 cannot continue to reset, and the relevant staff can rotate the turntable 300 and rotate the pin hole 303 to near the latch 520, and then rotate the latch 520 again so that the blocking block 521 is not blocked by the limiting column 501. At this time, the resetting effect of the spring 540 continues to drive the latch 520 to move, pushing the latch 520 into the pin hole 303. Through the arrangement of the blocking block 521 and the limiting column 501, the relevant staff does not need to use both hands to operate the locking structure 500 and rotate the turntable 300 at the same time.

[0048] In one embodiment of the present invention, a drainage hole is provided on the liquid collecting tank 100 , and a hole plug is provided at the drainage hole.

[0049] It should be noted that when the drilling machine 700 performs a drilling operation, it is usually equipped with a coolant, so that the collecting tank 100 can collect the coolant and discharge it through the drain hole.

[0050] In summary, according to the gear ring drilling positioning device of the embodiment of the present invention, the protrusion 301 in the center of the turntable 300 is precisely matched with the inner wall of the sleeve 601 of the gear ring 600, and the clamping structure 400 is stably fixed, thereby ensuring the accurate positioning of the gear ring during the drilling process and improving the drilling precision; the turntable 300 can be rotatably set on the table 200, and can be quickly locked and unlocked by the locking structure 500, thereby realizing the rapid clamping and replacement of the gear ring 600, significantly improving the production efficiency. The overall device has a compact structure, a reasonable layout, and a small footprint, and is suitable for use in limited spaces. It is particularly suitable for small and medium-sized enterprises and small and medium-sized production lines.
