Description

Technical Field

[0001] The invention relates to the field of quartz tube grinding and processing, and in particular to a grinding device for quartz tube processing. Background Art

[0002] When the existing dust removal and polishing device for quartz tube processing is used to polish the quartz tube, it is necessary to polish the inner wall, outer wall and both ends of the quartz tube respectively, which is troublesome and time-consuming to operate. In addition, the existing polishing device will generate a large amount of debris when working, which will cause the debris to splash and cannot be collected in time, polluting the work station. In addition, the quartz tube debris cannot be recovered in time, resulting in material waste.

[0003] Chinese patent CN117428652B discloses a dust removal and polishing device for quartz tube processing, including a processing table, with connecting seats installed on both sides of the processing table, a quartz tube inner support polishing mechanism installed on the left connecting seat, a quartz tube outer clamp polishing mechanism arranged on the quartz tube inner support polishing mechanism, and the inner and outer sides of the quartz tube are fixed and polished respectively by switching the quartz tube outer clamp polishing mechanism and the quartz tube inner support polishing mechanism; a dust removal mechanism is installed on the right connecting seat, and the dust removal mechanism is arranged on the outer side of the quartz tube inner support polishing mechanism, and the dust removal mechanism is driven to operate by the operation of the quartz tube inner support polishing mechanism to collect dust generated when polishing the quartz tube.

[0004] Although the above scheme ensures that the debris in the quartz tube can be collected when the inner wall of the quartz tube is polished, it is only applicable to quartz tubes with open ends. If one end of the quartz tube is in a closed state, the above polishing method is adopted. When the polishing device is extended into the quartz tube from the open end of the quartz tube, some of the polished debris will gather at the sealed end of the quartz tube. This is because the seal of the quartz tube is in a sealed state. When the dust removal mechanism absorbs the debris, the outside air flows into the quartz tube from between the inner wall of the quartz tube and the polishing device, thereby causing some of the debris to be brought into the sealed end of the quartz tube by the flowing air. In this way, when the polishing device moves to the sealed end of the quartz tube, the debris accumulated on the sealed end of the quartz tube is stirred by the polishing device, causing the inner wall of the quartz tube to be scratched.

A grinding rod is provided, and an air filling groove and an inhalation groove are provided on the grinding rod, so that the air filling groove inflates the quartz tube in a grinding state, and the inhalation groove sucks out the inflated gas, so that the debris remaining in the quartz tube can be discharged under the action of the airflow. The working principle is as follows: during the rotation of the grinding rod, the debris in the quartz tube falls and gathers in the quartz tube. At this time, the air filling groove on the inner end of the grinding rod inflates the quartz tube. Since one end of the quartz tube is closed, when the air filling groove inflates the quartz tube , air will flow from the gap between the grinding rod and the quartz tube toward the opening of the quartz tube, and the suction grooves evenly arranged around the inflation grooves will suck in the air flowing from the gap, so that the debris accumulated in the quartz tube is discharged from the inside of the quartz tube under the action of the airflow, and at the same time, the suction port of the suction groove on the side wall of the grinding rod can absorb the debris, ensuring that the debris will not accumulate in the quartz tube, and further ensuring that when the grinding rod grinds the quartz tube through the grinding unit, the debris will not be mixed into the grinding area between the grinding unit and the quartz tube, avoiding the situation where the debris scratches the inner wall of the quartz tube during grinding.

DETAILED DESCRIPTION

[0028] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Reference Figure 1-Figure 5 A grinding device for quartz tube processing, comprising a clamping unit 3 capable of clamping a quartz tube 2; comprising a grinding rod 1 arranged along the extension direction of the quartz tube 2 after being clamped by the clamping unit 3, the grinding rod 1 can extend into the quartz tube 2 along the extension direction of the quartz tube 2, an air filling groove 11 is provided on the end of the grinding rod 1 extending into the quartz tube 2, a plurality of suction grooves 12 are evenly arranged around the air filling groove 11, a suction port 121 of the suction groove 12 is provided on the side wall of the grinding rod 1, the air filling groove 11 injects air into the quartz tube 2, and the suction groove 12 absorbs the injected air and debris mixed in the air.

[0030] A first air pump 13 is provided at the end of the gas filling groove 11, and the first air pump 13 inflates the gas filling groove 11. The clamping unit 3 for clamping the quartz tube 2 is a prior art, so it is not repeated here. The debris is the quartz debris dropped from the quartz tube 2 during the grinding process of the grinding rod 1. Before the quartz tube 2 is ground, the quartz tube 2 needs to be clamped by the clamping unit 3. A moving seat 4 for driving the grinding rod 1 to move is provided at the end of the grinding rod 1. After the tube 2 is clamped by the clamping unit 3, the moving seat 4 drives the polishing rod 1 to gradually extend into the quartz tube 2 from the opening of the quartz tube 2 along the extension direction of the quartz tube 2. As the polishing rod 1 enters the quartz tube 2, the polishing rod 1 also starts to rotate. A polishing unit 7 is arranged on the side wall of the polishing rod 1. When the polishing rod 1 rotates, the polishing unit 7 can drive the polishing unit 7 to polish the inner wall of the quartz tube 2. The working principle of the polishing rod 1 being able to completely discharge the debris remaining in the quartz tube 2 during rotational polishing is as follows During the rotation of the grinding rod 1, the debris in the quartz tube 2 falls and gathers in the quartz tube 2. At this time, the grinding rod 1 is located in the gas charging groove 11 on the inner end of the quartz tube 2 to charge the quartz tube 2. Since one end of the quartz tube 2 is closed, when the gas charging groove 11 charges the quartz tube 2, the air will flow from the gap between the grinding rod 1 and the quartz tube 2 to the opening of the quartz tube 2, and the suction grooves 12 evenly arranged around the gas charging groove 11 will draw the air flowing from the gap. Inhalation, so that the debris accumulated in the quartz tube 2 is discharged from the inside of the quartz tube 2 under the action of the airflow, and at the same time, the suction port 121 of the suction groove 12 on the side wall of the polishing rod 1 can absorb the debris, ensuring that the debris will not accumulate in the quartz tube 2, and further ensuring that when the polishing rod 1 polishes the quartz tube 2 through the polishing unit 7, the debris will not be mixed into the polishing area between the polishing unit 7 and the quartz tube 2, avoiding the situation that the debris scratches the inner wall of the quartz tube 2 during polishing.

[0031] Reference Figure 3 , Figure 5 and Fig.10 A filter unit 5 is provided at one end of the suction slot 12 away from the suction port 121 . The filter unit 5 includes a filter screen 51 . The air drives the debris to pass through the filter screen 51 and is then discharged after being filtered. The debris remains on the filter screen 51 .

[0032] The filter screen 51 is evenly provided with filter holes.

[0033] Reference Figure 5 and Fig.10The filter unit 5 includes a filter shell 52, which is an annular shell structure. The filter shell 52 is sleeved on the polishing rod 1. The filter screen 51 is an annular structure. The filter screen 51 is arranged in the filter shell 52. The filter screen 51 divides the filter shell 52 into a filter chamber 521 and an exhaust chamber 522. Debris enters the filter chamber 521 from the suction groove 12 and is intercepted by the filter screen 51 and remains in the filter chamber 521. The air filtered by the filter screen 51 is discharged through the exhaust chamber 522.

[0034] Reference Figure 6 and Fig.10 A second air pump 523 capable of extracting air from the exhaust chamber 522 is provided at the upper portion of the exhaust chamber 522, a bracket 524 is provided on the outer periphery of the polishing rod 1, the polishing rod 1 is rotatably disposed on the bracket 524, and the filter shell 52 is fixedly connected to the bracket 524.

[0035] The end of the movable seat 4 is fixedly connected to the bracket 524, the bracket 524 will not rotate with the polishing rod 1, and the filter shell 52 is fixedly arranged on the bracket 524, so that when the polishing rod 1 rotates, the filter shell 52 will not rotate with the polishing rod 1, so that the second air pump 523 arranged on the exhaust chamber 522 is always located on the upper side of the exhaust chamber 522, and the second air pump 523 is started before the polishing rod 1 extends into the quartz tube 2, and the first air pump 13 and the second air pump 523 are started at the same time, the first air pump 13 fills the gas into the quartz tube 2 through the charging groove 11, and the second air pump 523 extracts the gas in the quartz tube 2 through the suction groove 12, so that a circulating airflow is formed in the quartz tube 2, and the flow direction of the airflow is toward the opening of the quartz tube 2, but the airflow is sucked by the suction groove 12 when passing through the suction port 121 of the suction groove 12, so that when the polishing rod 1 is polishing the quartz tube 2, the polished debris can be discharged smoothly.

[0036] Reference Fig.10 : A discharge hole 511 is opened on the peripheral wall of the filter screen 51, and the filter screen 51 is rotatably set in the filter shell 52. The shielding ring 53 is sleeved on the periphery of the filter screen 51 and the shielding ring 53 is fixedly connected to the inner ring wall of the filter shell 52 through the outer ring side wall. The width of the shielding ring 53 in the extension direction of the polishing rod 1 is smaller than the width of the filter screen 51 in the extension direction of the polishing rod 1. A discharge pipe 531 is vertically provided at the bottom of the shielding ring 53. The discharge pipe 531 passes through the bottom of the filter shell 52. When the filter screen 51 rotates, it drives the discharge hole 511 to rotate together, and the shielding ring 53 blocks the discharge hole 511. When the discharge hole 511 rotates to the bottom with the filter screen 51, the discharge hole 511 coincides with the discharge pipe 531.

[0037] The suction groove 12 sucks the debris into the filter chamber 521, and the filter 51 filters the air mixed with the debris, so that the debris remains in the filter chamber 521, and the air is discharged through the exhaust chamber 522. The shielding ring 53 set on the outer periphery of the filter 51 is used to shield the discharge hole 511 on the filter 51, that is, when the discharge hole 511 on the filter 51 is not directly below the filter 51, the debris accumulated in the filter chamber 521 cannot be discharged, so that the filter 51 is constantly filtering. The shell 52 rotates so that the discharge hole 511 on the rotating filter screen 51 can coincide with the discharge pipe 531. When the discharge hole 511 coincides with the discharge pipe 531, the debris accumulated in the filter cavity 521 can be discharged. It is worth noting that a collection bag 54 for collecting debris is provided at the lower part of the discharge pipe 531. When the discharge hole 511 on the filter screen 51 is in a staggered state with the discharge pipe 531, even the air in the filter cavity 521 cannot enter the collection bag 54.

[0038] Reference Figure 5 and Fig.10 A collecting bag 54 is sleeved at the lower part of the discharge pipe 531. The collecting bag 54 is used to collect debris discharged from the filter cavity 521. The collecting bag 54 is made of a flexible breathable fabric.

[0039] A collecting bag 54 is provided at the lower part of the discharge pipe 531 to collect the debris discharged from the filter chamber 521. The material of the collecting bag 54 is a flexible breathable fabric, which can ensure that when the discharge hole 511 on the filter screen 51 coincides with the discharge pipe 531, the debris in the filter chamber 521 can be discharged normally, and will not flow back into the filter chamber 521. This is because the collecting bag 54 is air-permeable. After the discharge hole 511 coincides with the discharge pipe 531, the debris in the filter chamber 521 and part of the airflow will After entering the collection bag 54, due to the air permeability of the collection bag 54, the air flow can be discharged from the collection bag 54, thereby avoiding the backflow of the air flow in the collection bag 54 and lifting the debris collected in the collection bag 54. If the collection bag 54 is made of airtight material, the air flow as the debris enters the collection bag 54 will lift the debris accumulated in the collection bag 54, and then the debris will re-enter the filter cavity 521. Setting the collection bag 54 as a flexible breathable fabric can avoid the above situation.

[0040] Reference Figure 5 A rotating ring 55 is rotatably provided on the end of the filter shell 52 facing the suction groove 12. The inner ring of the rotating ring 55 is fixedly connected to the polishing rod 1. The rotating ring 55 rotates synchronously with the polishing rod 1. The two ends of the connecting pipe 56 are respectively connected to the suction groove 12 and the rotating ring 55. The connection between the connecting pipe 56 and the rotating ring 55 is communicated with the filter chamber 521.

[0041] Since there are multiple suction grooves 12, there are also multiple connecting tubes 56 for discharging the debris sucked in the suction groove 12 into the filter chamber 521. When the grinding rod 1 rotates, the connecting tube 56 rotates synchronously with the grinding rod 1. In order to ensure that the connecting tube 56 will not be damaged due to collision when rotating with the grinding rod 1, a follower sleeve 57 is fixedly provided at one end of the rotating ring 55 facing the suction groove 12, and the follower sleeve 57 wraps all the connecting tubes 56.

[0042] Reference Fig.10 and Fig.11 : A driving unit 6 for driving the grinding rod 1 to rotate is arranged at the end of the grinding rod 1. The driving unit 6 is arranged on the bracket 524. After the grinding rod 1 is inserted into the quartz tube 2, the driving unit 6 is started.

[0043] The driving unit 6 includes a rotary driver 61, a gear 62 and a first gear ring 63. The rotary driver 61 is fixedly arranged on the bracket 524, the gear 62 is fixedly arranged on the output end of the rotary driver 61, the first gear ring 63 is fixedly arranged on the end of the polishing rod 1 along the axis of the polishing rod 1, the polishing rod 1 passes through the bracket 524 and rotates with the bracket 524, the movable seat 4 is fixedly connected to the bracket 524, the first gear ring 63 and the gear 62 are meshed with each other, and the rotary driver 61 is preferably a servo motor. After the clamping unit 3 clamps the quartz tube 2, the movable seat 4 drives the polishing rod 1 to extend from the opening of the quartz tube 2 into the quartz tube 2 through the bracket 524, and then the rotary driver 61 is started, and the rotary driver 61 drives the gear 62 to rotate. Since the gear 62 and the first gear ring 63 are meshed with each other and the first gear ring 63 is fixedly connected to the end of the polishing rod 1, the polishing rod 1 can be driven to rotate.

[0044] Reference Fig.10 A follower frame 59 is arranged on one side of the filter shell 52. The follower frame 59 is a rotating body frame structure. The follower frame 59 is fixedly connected to the end of the filter screen 51. The second gear ring 58 is fixedly arranged at one end of the follower frame 59 away from the filter screen 51. When the driving unit 6 is started, the second gear ring 58 is driven to rotate by the driving unit 6.

[0045] The second gear ring 58 is rotatably arranged on the bracket 524, and the second gear ring 58 is sleeved on the outer periphery of the first gear ring 63. The two sides of the gear 62 are respectively meshed with the first gear ring 63 and the second gear ring 58. In this way, when the rotary driver 61 is started, the rotary driver 61 drives the first gear ring 63 to rotate through the gear 62 and can also drive the second gear ring 58 to rotate. The second gear ring 58 drives the filter screen 51 to rotate through the follower frame 59. In this way, when the discharge hole 511 on the filter screen 51 does not overlap with the discharge pipe 531, the air containing debris entering the filter chamber 521 can be filtered through the filter screen 51, and the filtered air enters the exhaust chamber 522 for discharge.

[0046] Reference Figure 4 and Figure 7-Figure 9 : A grinding unit 7 is arranged on the grinding rod 1, and the grinding unit 7 includes a plurality of grinding plates 71. The grinding plates 71 are evenly arranged around the axis of the grinding rod 1, and the grinding plates 71 are staggered with the suction port 121 of the suction groove 12.

[0047] The grinding unit 7 also includes a push frame 72, a third air pump 73, a push groove 74, a connecting rod 75, a slide groove 76, a groove 77 and a support column 78. The groove 77 is opened on the side wall of the grinding rod 1 along the extension direction of the grinding rod 1. The support column 78 is fixedly arranged in the groove 77 along the width direction of the groove 77. The push frame 72 is interactively arranged in the groove 77 along the extension direction of the groove 77. The push frame 72 is located at the lower side of the support column 78. The two ends of the connecting rod 75 are respectively hinged to the push frame 72 and the grinding plate 71. The slide groove 76 is arranged along the length of the connecting rod 75. The connecting rod 75 is opened in the degree direction, the support column 78 passes through the slide groove 76, and the support column 78 slides with the slide groove 76 along the extension direction of the slide groove 76. The push groove 74 is set at the end of the groove 77, and the third air pump 73 is set on the push groove 74. When the third air pump 73 inflates the push groove 74, the push frame 72 slides out of the push groove 74, the push frame 72 slides in the groove 77, and the connecting rod 75 is unfolded, thereby changing the distance between the grinding plate 71 and the grinding rod 1, so that the grinding plate 71 can adapt to quartz tubes 2 with different inner diameters.

[0048] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
