Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a multi-station drilling equipment. Background Art

[0002] When drilling irregular materials that require deep holes, the drill bit acts on the material to perform deep hole operations. Due to the large depth of the hole, when the drill bit extends into the hole of the material, the friction and resistance of contact with the material will increase, especially for irregularly shaped materials and deep hole drilling, resulting in drill bit breakage. For this reason, we propose a multi-station drilling device. Utility Model Content

[0013] (III) Beneficial effects

[0014] The embodiment of the utility model provides a multi-station drilling device. It has the following beneficial effects:

[0015] 1. Install drill bits and reamers of the same specifications on adjacent drilling units to drill holes in the material in turn. The reamer of the same specifications is 0.02-0.03mm larger than the drill bit, and the hole wall roughness is much better than that of the drill bit. The resistance of the drill bit in deep hole processing will be reduced to the minimum. This drilling method will not cause the drill bit to break.

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Refer to the attached Figure 1-5A multi-station drilling device includes a base 1, a through hole is opened in the center of the base 1, a reduction motor is installed in the base 1, a column 2 perpendicular to the base 1 is installed in the through hole of the base 1, the reduction motor drives the column 2 to rotate, the column 2 is a non-cylindrical body, and the number of specific outer sides of the column 2 can be adjusted according to the number of times the tool is retracted. A slide rail 21 arranged along the direction of the column 2 is also installed on the outer side of the column 2. A drilling unit is slidably arranged on the slide rail 21. The slide rail 21 is slidably matched with a slider 34 installed on the side wall of the drilling unit, so that the drilling unit can be raised and lowered on the outer side of the column 2. The slide rail 21 is wedge-shaped, and the slider 34 is slidably engaged with the wedge. The control drilling unit can only be lifted up and down along the slide rail 21 to prevent it from falling off. The drilling units are arranged on the outer surface of the column 2 in sequence. The adjacent drilling units are installed with drill bits and reamers of the same specifications to drill holes in the material in sequence. The reamer of the same specifications is 0.02 to 0.03 mm larger than the drill bit, and the roughness of the hole wall is much better than that of the drill bit processing the hole wall. The resistance of the drill bit in processing deep holes will be reduced to a minimum. This drilling method will not cause the drill bit to break, so deep holes can be drilled without deep hole equipment and deep hole drills, and the cost is greatly reduced.

[0024] Furthermore, the drilling unit includes a platform 3, on which a motor 31 is installed. A connecting rod 32 is connected to the output end of the motor 31, and a mounting seat 33 is also connected to the connecting rod 32. The mounting seat 33 is vertically downward to facilitate drilling. The motor 31 also drives a screw rod 5 installed on the platform 3 through gears. The screw rod 5 cooperates with a nut fixed on the column 2. When the screw rod 5 rotates, the screw rod 5 rotates inside the column 2, so that the screw rod 5 drives the platform 3 to rise and fall along the direction of the screw rod 5.

[0025] Furthermore, a driving gear 4 is sleeved on the output end of the motor 31 , and the driving gear 4 is meshed with a passive gear 41 . The passive gear 41 can be a double gear or a double-layer gear. The passive gear 41 is meshed with a driven gear 42 , and both the passive gear 41 and the driven gear 42 are installed on the platform 3 .
