Description

Technical Field

[0001] This invention relates to the field of quartz crucible technology, and in particular to a device and method for horizontally drilling holes at the bottom arc position of a quartz crucible. Background Technology

[0002] Quartz glass crucibles are currently mainly produced by high-temperature electric arc melting. Before melting, high-purity quartz sand is poured into the inner surface of the mold. Using centrifugal force and a forming rod, the crucible-shaped rotating device is rotated back to the electrode rod. Then, the electrode is arced and inserted into the formed powder cavity, which is then rapidly melted into crucible-shaped quartz. After cooling, it is removed, thus completing the production of a quartz crucible blank.

[0003] In the manufacturing process of quartz crucibles, some crucibles require drilling holes at the bottom arc position. The requirement is that the crucible be placed flat on a table with the end facing down, and the hole must be horizontal to the ground. Currently, the drilling method is mainly manual. Before drilling, the crucible dimensions must be measured, and the drilling location marked. Different sized drill bits are used according to the size requirements, and the hole is drilled manually using a pneumatic drill. This manual drilling method, because the drilling location is at the arc position of the quartz crucible and not perpendicular to the tangent of the arc, easily causes scratches on the outer surface of the quartz crucible. Due to the arc surface, the drilling position is offset, resulting in an elliptical hole, and the hole orientation cannot be guaranteed to be horizontal to the ground. To improve this technology, a horizontal drilling device and method perpendicular to the center of the quartz crucible have been developed. Summary of the Invention

[0004] In order to solve the technical problems existing in the above-mentioned technologies, it is necessary to provide a device for horizontally drilling holes at the bottom arc position of a quartz crucible.

[0005] A device for horizontally drilling holes at the bottom arc position of a quartz crucible includes a processing platform, a bidirectional centering mechanism, and a drilling mechanism;

[0006] The upper surface of the processing platform has two parallel guide grooves, and a support plate is fixedly installed on the upper surface of the processing platform on one side perpendicular to the guide grooves.

[0007] The drilling mechanism includes a base, a longitudinal plate, a drilling device, a mounting plate, and a positioning rod. The base is slidably mounted on a support plate and can reciprocate on the support plate in a direction perpendicular to the guide groove. The longitudinal plate is vertically fixed to the base. The mounting plate is slidably mounted on the longitudinal plate and can move up and down along the longitudinal plate. The drilling device is perpendicular to the mounting plate and arranged along the length of the support plate. The positioning rod is vertically fixed to the upper end of the mounting plate and arranged along the length of the support plate, with the positioning rod located directly above the drilling device.

[0008] The bidirectional centering mechanism includes a power assembly, a left clamping plate, and a right clamping plate. The left and right clamping plates are located above the processing platform and are symmetrically arranged on both sides of the positioning rod. The lower ends of the left and right clamping plates pass through the guide groove and extend downward. The power assembly is located below the processing platform and is connected to the left and right clamping plates respectively, so as to drive the left and right clamping plates to move towards the center or separate towards both sides synchronously along the guide groove.

[0009] Preferably, the power assembly includes a rotating handle, a first connecting rod, a second connecting rod, a first telescopic member, and a second telescopic member; the rotating handle is rotatably disposed below the processing platform, and the initial position of the rotating handle is parallel to the left and right clamping plates; one end of the first connecting rod is rotatably connected to one end of the rotating handle, and the other end of the first connecting rod is rotatably connected to the left clamping plate, with the initial position of the first connecting rod perpendicular to the rotating handle; one end of the second connecting rod is rotatably connected to the end of the rotating handle away from the first connecting rod, and the other end of the second connecting rod is rotatably connected to the right clamping plate, with the initial position of the second connecting rod perpendicular to the rotating handle; the first telescopic member is connected to the left clamping plate, and the second telescopic member is connected to the right clamping plate.

[0010] Preferably, the support plate is provided with a transverse drive rod, which is driven by a base screw to drive the base to reciprocate on the support plate in a direction perpendicular to the guide groove.

[0011] Preferably, the support plate is provided with a sliding groove for the base to move.

[0012] Preferably, the longitudinal plate is provided with a longitudinal drive rod, which is driven by a lead screw of the mounting plate to drive the mounting plate to move up and down along the longitudinal plate.

[0013] Preferably, the longitudinal plate is provided with guide rods that allow the drilling equipment to move up and down.

[0014] Preferably, the mounting plate is provided with a scale, and the drilling equipment can move up and down along the mounting plate to adjust the distance between the drilling equipment and the positioning rod.

[0015] Preferably, a limiting plate is slidably provided at the end of the positioning rod away from the mounting plate, so that the limiting plate can move along the positioning rod. The limiting plate is connected to the transverse drive rod through a traction line. The transverse drive rod drives the base to approach the quartz crucible, and the traction line pulls the limiting plate to approach the quartz crucible simultaneously. The shape of the limiting plate is adapted to the arc-shaped structure at the bottom of the quartz crucible.

[0016] Preferably, the surfaces of the left and right clamps that contact the quartz crucible have an arc-shaped structure.

[0017] It is also necessary to provide a method for horizontally drilling holes at the bottom arc position of a quartz crucible.

[0018] A method for horizontally drilling a hole at the bottom arc position of a quartz crucible, using the aforementioned horizontal drilling device for the bottom arc position of a quartz crucible, includes the following steps.

[0019] S1: Adjust the distance between the positioning rod and the drilling equipment in advance according to the drilling position of the quartz crucible;

[0020] S2: Place the quartz crucible with the opening facing down on the processing platform, and control the power unit to drive the left and right clamps to move towards the quartz crucible simultaneously, using the left and right clamps to clamp the quartz crucible.

[0021] S3: Control the mounting plate to move downwards along the longitudinal plate so that the positioning rod contacts the bottom surface of the quartz crucible, thereby determining the drilling position and ensuring that the diameter of the quartz crucible coincides with the axis of the drilling equipment;

[0022] S4: Start the drilling equipment, control the base to slowly move along the support plate towards the quartz crucible until it contacts the quartz crucible, keep the drill bit running, apply force in the feed direction, and perform drilling operation on the quartz crucible;

[0023] S5: After the hole is drilled through, control the base to slowly move away from the quartz crucible along the support plate, turn off the drilling equipment, control the mounting plate to move upward along the longitudinal plate, so that the positioning rod is disengaged from the quartz crucible, control the drive assembly to drive the left and right clamping plates to separate synchronously, remove the quartz crucible, and one drilling operation is completed.

[0024] As can be seen from the above technical solution, the horizontal drilling device and method for the bottom arc position of the quartz crucible provided by the present invention drives the left and right clamping plates to move synchronously through the power component, thereby realizing the pushing, centering, and clamping and fixing of the quartz crucible. At the same time, by adjusting the longitudinal position of the drilling equipment, the drilling position is determined by using the positioning rod and the preset distance between the drilling equipment, so that the drilling position of the quartz crucible is accurate, avoiding the hole being out of round. The hole orientation must be horizontal to the ground, so that the center line of the completed hole is perpendicular to the center line of the quartz crucible. Furthermore, it can reduce the repetitive measurement, scribing, marking and other work during drilling, improve the drilling efficiency of the quartz crucible, and improve the pass rate of quartz crucible drilling.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] In the description of this invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0037] Please refer to Figure 1 , Figure 2This invention provides a horizontal drilling device for the bottom arc position of a quartz crucible, including a processing platform 01, a bidirectional centering mechanism 02, and a drilling mechanism 03. Two parallel guide grooves 11 are formed on the upper surface of the processing platform 01. A support plate 04 is fixedly mounted on the upper surface of the processing platform 01 and on one side perpendicular to the guide grooves 11. The drilling mechanism 03 includes a base 31, a longitudinal plate 32, a drilling device 33, a mounting plate 34, and a positioning rod 35. The base 31 is slidably mounted on the support plate 04 and can reciprocate along the support plate 04 in a direction perpendicular to the guide grooves 11. The longitudinal plate 32 is vertically fixed on the base 31. The mounting plate 34 is slidably mounted on the longitudinal plate 32 and can move up and down along the longitudinal plate 32. The drilling device 33 is perpendicular to the mounting plate 34 and along the support plate 04. The positioning rod 35 is vertically fixed to the upper end of the mounting plate 34 and is set along the length direction of the support plate 04. The positioning rod 35 is located directly above the drilling equipment 33. The bidirectional centering mechanism 02 includes a power component 21, a left clamping plate 22, and a right clamping plate 23. The left clamping plate 22 and the right clamping plate 23 are located above the processing platform 01 and are symmetrically arranged on both sides of the positioning rod 35. The lower ends of the left clamping plate 22 and the right clamping plate 23 pass through the guide groove 11 and extend downward. The power component 21 is set below the processing platform 01 and is connected to the left clamping plate 22 and the right clamping plate 23 respectively, so as to drive the left clamping plate 22 and the right clamping plate 23 to move towards the center or separate towards both sides along the guide groove 11 simultaneously, so as to realize the pushing, centering, and clamping and fixing of the quartz crucible 10.

[0038] Please refer to Figure 3In one embodiment, the power assembly 21 includes a rotating handle 211, a first connecting rod 212, a second connecting rod 213, a first telescopic member 214, and a second telescopic member 215. The rotating handle 211 is rotatably disposed below the processing platform 01. The initial position of the rotating handle 211 is parallel to the left clamping plate 22 and the right clamping plate 23. One end of the first connecting rod 212 is rotatably connected to one end of the rotating handle 211, and the other end of the first connecting rod 212 is rotatably connected to the left clamping plate 22. The initial position of the first connecting rod 212 is perpendicular to the rotating handle 211. One end of the second connecting rod 213 is rotatably connected to the end of the rotating handle 211 away from the first connecting rod 212, and the other end of the second connecting rod 213 is rotatably connected to the right clamping plate 23. The initial position of the second connecting rod 213 is perpendicular to the rotating handle 211. The first telescopic member 214 is connected to the left clamping plate 22, and the second telescopic member 215 is connected to the right clamping plate 23. The first telescopic component 214 and the second telescopic component 215 can be any one of a cylinder, a hydraulic cylinder, or an electric telescopic rod. When the quartz crucible 10 needs to be moved and centered, the first telescopic member 214 and the second telescopic member 215 can retract simultaneously. When the first telescopic member 214 pushes the left clamping plate 22, the first connecting rod 212 will give a thrust to the rotating handle 211, causing the rotating handle 211 to rotate and simultaneously pull the second connecting rod 213, causing the second connecting rod to drive the right clamping plate 23 to move synchronously. At the same time, the second telescopic member 215 will also push the right clamping plate 23, and the second connecting rod 213 will also give a thrust to the rotating handle 211, causing the rotating handle 211 to rotate and simultaneously pull the first connecting rod 212, causing the first connecting rod 212 to also drive the left clamping plate 22 to move synchronously. By utilizing the interaction of the first telescopic member 214 and the second telescopic member 215, the left clamping plate 22 and the right clamping plate 23 can move synchronously to ensure the movement and centering of the quartz crucible 10 and to clamp and fix the quartz crucible 10. Of course, if either the first telescopic component 214 or the second telescopic component 215 malfunctions, the left clamping plate 22 and the right clamping plate 23 can still move synchronously, thus ensuring smooth operation.

[0039] In one embodiment, a transverse drive rod 05 is provided on the support plate 04. The transverse drive rod 05 is driven by a lead screw to drive the base 31 to reciprocate on the support plate 04 in a direction perpendicular to the guide groove 11.

[0040] In one embodiment, the support plate 04 is provided with a groove 41 for the base 31 to move; thereby providing guidance and limiting function for the base 31, enabling the base 31 to move laterally in a straight line along the support plate 04, so as to ensure the precise lateral adjustment of the drilling equipment 33.

[0041] In one embodiment, a longitudinal drive rod 06 is provided on the longitudinal plate 32, and the longitudinal drive rod 06 is driven by a lead screw to drive the mounting plate 34 to move up and down along the longitudinal plate 32.

[0042] In one embodiment, a guide rod 07 is provided on the longitudinal plate 32 for the drilling equipment 33 to move up and down, thereby providing guidance and limiting function for the drilling equipment 33, enabling the drilling equipment 33 to move up and down linearly along the longitudinal plate 32, so as to ensure the precise longitudinal adjustment of the drilling equipment 33.

[0043] In one embodiment, the mounting plate 34 is provided with a scale, and the drilling device 33 can move up and down along the mounting plate 34, thereby adjusting the distance between the drilling device 33 and the positioning rod 35 to obtain an accurate drilling position.

[0044] Please refer to Figure 7 , Figure 8 In one embodiment, a limiting plate 08 is slidably provided at the end of the positioning rod 35 away from the mounting plate 34, allowing the limiting plate 08 to move along the positioning rod 35. The limiting plate 08 is connected to the transverse drive rod 05 via a traction line 09. The traction line 09 is guided to the transverse drive rod 05 via a pulley, and a roller capable of winding and retracting the traction line 09 is installed on the transverse drive rod 05. During drilling, when the transverse drive rod 05 moves the base 31 closer to the quartz crucible 10, the rotation of the transverse drive rod 05 will cause the roller to rotate synchronously. At this time, the roller will retract the traction line 09, causing the traction line 09 to pull the limiting plate 08 closer to the quartz crucible 10, thus bringing the limiting plate 08 into contact with the quartz crucible 10. Since the shape of the limiting plate 08 is adapted to the arc-shaped structure at the bottom of the quartz crucible 10, it can be ensured that the limiting plate 08 and the arc-shaped part at the bottom of the quartz crucible 10 are in close contact. When the drilling operation begins, the drilling device 33 applies a feed force to the quartz crucible 10. At this time, the forces applied by the drilling device 33 and the limiting plate 08 to the quartz crucible 10 are exactly opposite. Due to the material properties of the quartz crucible 10, it is relatively brittle and prone to chipping or cracking when subjected to unbalanced forces. The opposing forces between the limiting plate 08 and the drilling device 33 not only ensure the stability of the quartz crucible 10 and improve drilling accuracy, but also balance the force exerted by the drilling device 33 on the quartz crucible 10, preventing chipping or cracking. An anti-slip pad 81 is provided on the side of the limiting plate 08 that contacts the quartz crucible 10.

[0045] Please refer to Figure 6In one embodiment, the surfaces of the left clamping plate 22 and the right clamping plate 23 that contact the quartz crucible 10 are arc-shaped, which allows the left clamping plate 22 and the right clamping plate 23 to make better contact with the quartz crucible 10 and has a larger contact area, thus ensuring the clamping stability of the left clamping plate 22 and the right clamping plate 23 on the quartz crucible 10. Secondly, the arc-shaped structure of the left clamping plate 22 and the right clamping plate 23 can ensure that the quartz crucible 10 is not deviated during the pushing and centering process, and can make the movement of the quartz crucible 10 more precise.

[0046] This invention provides a method for horizontally drilling a hole at the bottom arc position of a quartz crucible, comprising the following steps:

[0047] S1: Adjust the distance between the positioning rod 35 and the drilling equipment 33 in advance according to the drilling position of the quartz crucible 10;

[0048] S2: Place the quartz crucible 10 with the open end facing down on the processing platform 01, and control the power component 21 to drive the left clamping plate 22 and the right clamping plate 23 to move towards the quartz crucible 10 simultaneously, using the left clamping plate 22 and the right clamping plate 23 to clamp the quartz crucible 10.

[0049] S3: Control the mounting plate 34 to move downward along the longitudinal plate 32, so that the positioning rod 35 contacts the bottom surface of the quartz crucible 10, thereby determining the drilling position and ensuring that the diameter of the quartz crucible 10 coincides with the axis of the drilling equipment 33;

[0050] S4: Start the drilling equipment 33, control the base 31 to slowly move along the support plate 04 towards the quartz crucible 10 until it contacts the quartz crucible 10, keep the drill bit running, apply force in the feed direction, and perform drilling operation on the quartz crucible 10.

[0051] S5: After the hole is drilled through, control the base 31 to move slowly away from the quartz crucible 10 along the support plate 04, shut down the drilling equipment 33, control the mounting plate 34 to move upward along the longitudinal plate 32, so that the positioning rod 35 is disengaged from the quartz crucible 10, control the drive assembly to drive the left clamping plate 22 and the right clamping plate 23 to separate synchronously, remove the quartz crucible 10, and one drilling is completed.

[0052] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. Those skilled in the art will understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present invention are still within the scope of the invention.
