Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a high-precision quartz cylinder drilling device. Background Art

[0002] A quartz cylinder is a hollow quartz product. Due to the production process of quartz columns, the production of quartz cylinders requires a hole to be drilled in the middle of the quartz column, which is also one of the common production methods of current quartz cylinders.

[0003] Place the quartz column at a designated position, and then the motor drives the hole opener to drill the quartz column. Since the contact between the quartz column and the hole opener will generate vibration, this vibration will cause the hole opener to deflect, resulting in the drilled hole not meeting the requirements and producing defective products. The current solution is generally to reduce the rotation speed of the hole opener, thereby reducing the probability and amplitude of vibration deflection, but this will also reduce the production efficiency. Therefore, a high-precision quartz cylinder drilling device is proposed. Content of the Utility Model

[0004] The technical solution adopted by the utility model to solve the technical problem is: a high-precision quartz cylinder drilling device, including an operating table. The top side wall of the operating table is fixedly connected with two columns. The end of the column far away from the operating table is fixedly connected with a connecting plate. A fixed box is arranged between the two connecting plates. The inner top of the fixed box and the side walls near both ends are fixedly connected with limiting rods. A descending plate is telescopically and movably connected in the limiting rods. The two ends of the descending plate are slidably sleeved on the limiting rods. The middle of the bottom side wall of the descending plate is rotatably connected with a drilling screw rod. One end of the descending plate near the drilling screw rod is detachably connected with a motor. The output end of the motor is fixedly connected with the top end of the drilling screw rod.

[0005] As a preferred technical solution of the utility model, one end of the limiting rod is fixedly connected with a protective cover. The protective cover is of a conical structure. The drilling screw rod is inserted through the middle of the protective cover. One positioning column is fixedly connected to each of the two opposite side walls of the fixed box. The positioning column is fixedly connected with one end of the connecting plate through the side wall far away from the fixed box.

[0006] As a preferred technical solution of the utility model, an adjusting column is telescopically inserted into the positioning column. One end edge of the adjusting column located inside the positioning column is fixedly connected with a clamping plate. The side wall of the positioning column opposite to the clamping plate is uniformly and throughly provided with slots. Plug rods are inserted into the slots. The clamping plate corresponds to the end of the plug rod located inside the positioning column. The end of the adjusting column far away from the clamping plate is fixedly connected with a supporting plate. The supporting plate is located below the bottom end of the descending plate.

[0007] As a preferred technical solution of the present utility model, a bottom groove is formed in the middle of the side wall of the top of the operation table. An annular inflatable rubber pad is fixedly connected to the inner wall of the bottom groove. A micro air pump is inlaid in the operation table, and the output end of the micro air pump is communicated with the inside of the inflatable rubber pad through a pipeline.

[0008] As a preferred technical solution of the present utility model, a support plate is provided at the bottom of the bottom groove. A telescopic rod is inlaid in the operation table and below the bottom groove. The output end of the telescopic rod extends into the bottom groove and is fixedly connected to the bottom side wall of the support plate. A quartz column is inserted into the bottom groove.

[0009] The present utility model has the following advantages: Connect the drilling screw to the descending plate, and drive the drilling screw to gradually descend by means of natural descent. In this way, when a large vibration and bump occur during hole opening, the descending plate can move up and down along the limiting rod, thereby discharging the force generated by the bump. At the same time, due to the limitation of the limiting rod, it can be ensured that the descending plate will not be deflected after the bump and still remain in place to descend, so that the drilling screw can be prevented from being deflected, thereby ensuring the quality of the hole opening and avoiding the appearance of defective products.

[0010] To prevent the flying chips generated by the stuck hole from affecting the staff, a protective cover is provided to cover the processing point, which can block the flying chips generated by the processing, thereby improving the safety of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present utility model will be further described below with reference to the drawings.

[0016] Please refer to Figures 1-3, a high-precision quartz cylinder drilling device of the present utility model includes an operating table 1. On the top side wall of the operating table 1, two columns 2 are fixedly connected. At the end of the column 2 far from the operating table 1, a connecting plate 3 is fixedly connected. A fixed box 6 is arranged between the two connecting plates 3. On the inner top of the fixed box 6 and on the side walls near both ends, limiting rods 9 are fixedly connected. A descending plate 20 is telescopically and movably connected in the limiting rod 9. The descending plate 20 is slidably sleeved on the limiting rod 9 through both ends thereof. In the middle of the bottom side wall of the descending plate 20, a drilling screw rod 7 is rotatably connected. Inside one end of the descending plate 20 close to the drilling screw rod 7, a motor 11 is detachably connected. The output end of the motor 11 is fixedly connected to the top end of the drilling screw rod 7;

[0017] One end of the limiting rod 9 is fixedly connected with a protective cover 8. The protective cover 8 is of a conical structure. The drilling screw rod 7 is inserted through the middle of the protective cover 8. On both side walls of the fixed box 6 far from each other, a positioning column 4 is fixedly connected. The positioning column 4 is fixedly connected to one end of the connecting plate 3 through the side wall far from the fixed box 6. An adjusting column 5 is telescopically inserted in the positioning column 4. At the edge of the end of the adjusting column 5 located inside the positioning column 4, a clamping plate 17 is fixedly connected. On the side walls of the positioning column 4 opposite to the clamping plate 17, slots 18 are uniformly penetrated. An inserting rod 19 is inserted in the slot 18. The clamping plate 17 corresponds to the end of the inserting rod 19 located inside the positioning column 4. The end of the adjusting column 5 far from the clamping plate 17 is fixedly connected with a supporting plate 10. The supporting plate 10 is located below the bottom end of the descending plate 20.

[0018] As the technical effect of this solution: Because there is no driving component, it is necessary to manually lift the descending plate 20, then place the quartz column in the bottom groove 12, and then lower the drilling screw rod 7 to ensure that the bottom end of the drilling screw rod 7 abuts against the center point of the opening. After that, start the motor 11 to drive the drilling screw rod 7 to rotate to drill the quartz column. As the drilling progresses, the descending plate 20 will also descend synchronously. The established limiting rod 9 can limit the descending plate 20 to ensure that the descending plate 20 will not deflect during the descending process. When there is bumpy vibration, due to the limitation of the limiting rod 9, the descending plate 20 will be driven to rise and then fall. Generally, this process is most likely to deviate, but the limiting rod 9 can ensure that the drilling screw rod 7 is always in place, reducing the waste product generation rate. The established protective cover 8 can block the flying chips generated by the opening, improving the safety of the staff.

[0019] In the middle of the top side wall of the operating table 1, a bottom groove 12 is opened. On the inner wall of the bottom groove 12, an annular inflatable rubber pad 15 is fixedly connected. A micro air pump 16 is inlaid in the operating table 1. The output end of the micro air pump 16 is communicated with the inside of the inflatable rubber pad 15 through a pipeline. At the bottom of the bottom groove 12, a supporting plate 13 is arranged. A telescopic rod 14 is inlaid in the operating table 1 and below the bottom groove 12. The output end of the telescopic rod 14 extends into the bottom groove 12 and is fixedly connected to the bottom side wall of the supporting plate 13. A quartz column is inserted in the bottom groove 12.

[0020] The technical effect of this solution is: the quartz column to be processed is inserted into the bottom groove 12, and its bottom end is fitted with the support plate 13. The quartz column can be positioned by the inflatable rubber pad 15 to ensure the stability of the quartz column itself and avoid the opening being deflected due to the instability of the quartz column itself, thereby affecting the quality of the product or even producing waste products.

[0021] Specifically, when the utility model is used, the quartz column is first inserted into the bottom groove 12, and after the quartz column and the support plate 13 are fitted together, the micro air pump 16 is started to fill the gas into the inflatable rubber pad 15 through the pipeline. At this time, the inflatable rubber pad 15 will expand because the inside is filled with gas. As the inflatable rubber pad 15 expands, a clamping force will be generated on the quartz column, thereby realizing the positioning of the quartz column. Because the inflatable rubber pad 15 is an annular structure, it can ensure that the quartz column is at the center point after inflation and clamping, which is convenient for the positioning of the drilling screw 7. After the quartz column is placed, the drilling screw 7 is lowered to contact the quartz column, and the drilling screw 7 is first driven at a low speed to open a hole for positioning. When the drilling screw After the bottom end of 7 enters the quartz column, the rotation speed of the drilling screw 7 is gradually increased to achieve efficient hole opening, which can reduce the probability of deflection. As the processing proceeds, the drop plate 20 gradually descends. In order to avoid excessive hole opening, the adjustment column 5 is lowered in advance, and the insertion rod 19 is inserted into the slot 18 at different positions. The position of the support plate 10 is limited by the contact between the clamping plate 17 and the insertion rod 19. When the drop plate 20 descends and fits the support plate 10, it will no longer descend, effectively avoiding the problem of excessive hole clamping. After the processing is completed, the gas is extracted by the micro air pump 16, and then the telescopic rod 14 is started to drive the support plate 13 to lift upward, thereby ejecting the quartz tube from the bottom groove 12 for easy material removal.

[0022] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
