DETAILED DESCRIPTION

[0021] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0022] The quartz crucible grinding device according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0023] like Figure 1-Figure 4As shown, the quartz crucible grinding device according to the embodiment of the present application may include a support frame 10 , a support table 20 , a clamping device 30 , a retractable device 40 and a grinding device 50 .

[0024] The support platform 20 is movably disposed on the support frame 10 and a through hole 21 is provided in the middle of the support platform 20. The clamping device 30 is disposed on the bottom wall of the support frame 10 and is located below the support platform 20.

[0025] It should be noted that the support frame described in this embodiment is composed of a bottom plate, a top plate and four pillars, wherein the four pillars are symmetrically distributed in pairs between the bottom plate and the top plate.

[0026] The retractable device 40 is disposed on the top wall of the support frame 10, and the output end of the retractable device 40 is fixedly connected to the support platform 20 via a connecting frame 41. It should be noted that the retractable device 40 described in this embodiment can be a cylinder, a hydraulic cylinder or an electric retractable rod.

[0027] The grinding device 50 may include a support plate 51 , a grinding mechanism 52 , a transmission mechanism 53 and a driving assembly 54 , wherein the support plate 51 is rotatably disposed on the support platform 20 and is located above the through hole 21 , and a through slot 501 is formed on the support plate 51 .

[0028] The grinding mechanism 52 is rotatably arranged in the through groove 501, the transmission mechanism 53 is fixedly arranged on the support platform 20, and the transmission mechanism 53 is connected to the grinding mechanism 52, and the driving component 54 is arranged on the support platform 20, and the driving component 54 is respectively connected to the grinding mechanism 52 and the transmission mechanism 53.

[0029] Specifically, when the circular groove at the bottom of the inner cavity of the quartz crucible needs to be polished, the relevant staff first needs to place the quartz crucible to be polished on the bottom wall of the support frame 10, and then control the clamping device 30 to clamp and fix the quartz crucible in the center.

[0030] Then, the staff controls the output end of the retractable device 40 to extend and push the support table 20 to drive the grinding device 50 to move downward until the grinding mechanism 52 in the grinding device 50 contacts the bottom wall of the inner cavity of the quartz crucible (the bottom of the circular groove).

[0031] Then, the staff controls the driving assembly 54 to drive the grinding mechanism 52 to swing. At the same time, the driving assembly 54 cooperates with the transmission mechanism 53 to drive the grinding mechanism 52 to rotate during the reciprocating swing by driving the support table 20, thereby achieving comprehensive grinding of the circular surface groove of the quartz crucible. Compared with manual grinding, it not only shortens the grinding cycle and improves the overall production efficiency, but also effectively ensures the consistency of product quality.

[0032] In one embodiment of the present application, Figure 2 and Figure 4 As shown, the clamping device 30 may include two sliders 31 , a first driving mechanism 32 , a threaded rod 33 and two clamping mechanisms 34 .

[0033] Among them, two symmetrically distributed slide grooves 11 are provided on the bottom wall of the support frame 10, two sliders 31 are slidably arranged in the corresponding slide grooves 11, and the first driving mechanism 32 is arranged on the side wall of the support frame 10. It should be noted that the first driving mechanism 32 described in this embodiment can be a driving motor.

[0034] The threaded rod 33 is horizontally and rotatably arranged in the bottom wall of the support frame 10, and the threaded rod 33 is threadedly connected to the two sliders 31 respectively, wherein one end of the threaded rod 33 passes through the support frame 10 and is connected to the output end of the first driving mechanism 32, and the two clamping mechanisms 34 are respectively arranged on the corresponding sliders 31.

[0035] It should be noted that the threaded rod 33 described in this embodiment may be a threaded rod with bidirectional threads, that is, the two sliders 31 can be driven to slide toward or away from each other by rotating the threaded rod 33 .

[0036] In order to clearly explain the above embodiment, in one embodiment of the present application, as Figure 2 As shown, the clamping mechanism 34 may include a support seat 341 , a clamping plate 342 , two side-by-side guide rods 343 and two springs 344 .

[0037] The support seat 341 is fixedly disposed on the slider 31 , and the clamping plate 342 is movably disposed on one side of the support seat 341 , wherein the clamping surface of the clamping plate 342 may be an arc-shaped surface.

[0038] In the embodiment of the present application, in order to prevent the clamping plate 342 from causing clamping marks on the quartz crucible when clamping the quartz crucible, a protective pad may be provided on the clamping surface of the clamping plate 342, wherein the protective pad may be a rubber pad.

[0039] One end of the two guide rods 343 is fixedly connected to the clamping plate 342, and the other end of the two guide rods 343 passes through the support seat 341. The two springs 344 are respectively mounted on the corresponding guide rods 343, and one end of the spring 344 is fixedly connected to the support seat 341, and the other end of the spring 344 is fixedly connected to the clamping plate 342.

[0040] It is understandable that when the quartz crucible needs to be clamped and fixed, the staff first needs to place the quartz crucible to be polished on the bottom wall of the support frame 10 and in front of the two clamping mechanisms 34. Then, the staff controls the first driving mechanism 32 to drive the threaded rod 33 to rotate, and the rotating threaded rod 33 drives the two sliders 31 to drive the two clamping mechanisms 34 to move toward each other, and clamp the quartz crucible.

[0041] It should be particularly noted that when the clamping plate 342 in the clamping mechanism 34 contacts the quartz crucible, the clamping plate 342 moves on the support seat 341 through the guide rod 343 and compresses the spring 344, and at the same time, the reverse force of the spring 344 acts on the quartz crucible through the clamping plate 342. Thus, the quartz crucible is clamped and fixed by the tension of the spring 344, and this fixing method can prevent the clamping plate 342 from causing hard damage to the quartz crucible when clamping and fixing it.

[0042] In one embodiment of the present application, Figure 3 and Figure 4 As shown, the grinding mechanism 52 may include a support column 521 , a sector gear 522 , a plurality of clamping claws 523 , a locking nut 524 and a grinding head 525 .

[0043] The support column 521 is rotatably disposed in the through slot 501 via a rotating shaft, and the top end of the support column 521 is fixedly connected to the sector gear 522 .

[0044] It should be noted that the support column 521 described in this embodiment can be an electric telescopic rod. It is understandable that by setting the support column 521 as an electric telescopic rod, the grinding head 525 can grind the circular grooves of the quartz crucible with different radii by adjusting the length of the support column 521.

[0045] Multiple clamping claws 523 are distributed in a circular array on the bottom end wall of the support column 521. For example, the multiple clamping claws 523 can be 2, 3, 4 clamping claws, etc. The specific number of settings can be selected according to actual conditions and is not limited here.

[0046] The locking nut 524 is sleeved on the multiple clamping claws 523 and threadedly connected to the multiple clamping claws 523 . The grinding head 525 is inserted between the multiple clamping claws 523 through a connecting rod.

[0047] It is understandable that, before the circular groove of the quartz crucible needs to be polished, the relevant staff can select a suitable polishing head 525 according to the actual situation, and then insert the connecting rod on the selected polishing head 525 between the multiple clamping claws 523. Then, the staff manually rotates the locking nut 524 to gather the multiple clamping claws 523 and lock and fix the polishing head 525.

[0048] Further, in one embodiment of the present application, Figure 3 and Figure 4 As shown, the transmission mechanism 53 may include a gear ring 531 and a tension spring 532, wherein the gear ring 531 is sleeved on the support plate 51 and fixedly connected to the support platform 20. One end of the tension spring 532 is fixedly connected to the end wall of the through slot 501, and the other end of the tension spring 532 is fixedly connected to the support column 521.

[0049] Further, in one embodiment of the present application, Figure 2-Figure 4 As shown, the driving assembly 54 may include a second driving mechanism 541, an incomplete gear 542 and a gear 543, wherein the second driving mechanism 541 is fixedly disposed on the supporting plate 51. It should be noted that the second driving mechanism 541 described in this embodiment may be a servo motor.

[0050] The incomplete gear 542 and the gear 543 are sequentially sleeved and fixed on the output end of the second driving mechanism 541 , wherein the incomplete gear 542 is intermittently meshed with the sector gear 522 , and the gear 543 is meshed with the ring gear 531 .

[0051] It should be noted that the incomplete gear 542 described in this example is a gear with half meshing teeth.

[0052] Specifically, when it is necessary to grind the circular groove of the quartz crucible, the staff can control the second driving mechanism 541 to drive the incomplete gear 542 and the gear 543 to rotate synchronously, and the rotating incomplete gear 542 is intermittently meshed with the fan gear 522. When the rotating incomplete gear 542 is meshed with the fan gear 522, the incomplete gear 542 drives the fan gear 522 to drive the support column 521 to swing and stretch the tension spring 532; when the fan gear 522 is not meshed with the incomplete gear 542, the support column 521 swings back under the tension of the tension spring 532. At this time, the reciprocating support column 521 drives the grinding head 525 to swing and grind the circular groove of the quartz crucible.

[0053] At the same time, since the gear 543 is meshed with the ring gear 531 and the ring gear 531 is fixed, when the gear 543 rotates, the gear 543 drives the support plate 51 to rotate through the second driving mechanism 541, and the rotating support plate 51 drives the grinding head 525 to rotate synchronously during the reciprocating swing process, thereby achieving comprehensive grinding of the circular surface groove of the quartz crucible.

[0054] As a possible situation, in order to increase the grinding effect of the grinding head 525, a small motor can be arranged between the grinding head 525 and the connecting rod, and the grinding head 525 can be driven by the motor to rotate to improve the grinding effect of the groove on the round surface of the quartz crucible.

[0055] In summary, the quartz crucible grinding device of the embodiment of the present application can flexibly adjust the grinding angle and efficiently grind the concave surface of the inner wall of the quartz crucible, which not only shortens the grinding cycle but also improves the overall production efficiency.
