Description

Technical Field

[0001] The utility model relates to an auxiliary device for a radial drill, specifically an auxiliary device for a deep hole drill of a radial drill. Background Art

[0002] A radial drill is a drill press in which the rocker arm can rotate and lift around the column, and usually the spindle box moves horizontally on the rocker arm. When machining a hole on a vertical drill press, the centering of the tool and the workpiece is achieved by moving the workpiece, which is obviously very inconvenient for some large and heavy workpieces; while a radial drill press can center by moving the position of the tool axis, which brings great convenience to machining holes on large and heavy workpieces in single-piece and small-batch production.

[0003] Drilling is to drill a hole in a material with a high-speed rotating drill bit. Since a large amount of drill chips will accumulate on the drill bit during the drilling process, when the drilling depth is relatively shallow, the high-speed rotating drill bit itself will discharge the drill chips; as the drilling depth gradually increases, the difficulty of discharging chips by rotation will gradually increase; when the drilling is too deep, the undischarged drill chips will affect the drilling effect and reduce the drilling formability. And when the drill chips accumulate to a certain extent, the service life of the drill bit will be greatly reduced.

[0004] Due to the fact that under the action of the high-speed rotation of the drill bit, the relatively light drill chips will stick to the drill bit. If not deeply cleaned, when the drill bit with adhered drill chips further opens a hole, the drill chips will interfere with the drilling efficiency of the drill bit, greatly reducing the formability of the drilling, and even damaging the drill bit during the drilling operation.

[0041] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0042] Please refer to Figures 1 to 8 , as an embodiment of the present utility model, the deep hole drilling auxiliary device for a radial drilling machine includes a base 1 and a protective sleeve 101 fixedly installed on the base 1; a cross bar 6 is arranged on the base 1;

[0043] A transverse positioning mechanism is arranged on the cross bar 6, and a drill bit support 2 is connected to the transverse positioning mechanism. The transverse positioning mechanism can drive the drill bit support 2 to displace along the length direction of the cross bar 6;

[0044] A drilling mechanism is arranged on the base 1. The drilling mechanism can drive the cross bar 6 to approach or move away from the base 1 along the length direction of the protective sleeve 101, so as to drive the drill bit support 2 to approach or move away from the base 1, and its trajectory of approaching or moving away from the base 1 is reciprocally increasing;

[0045] A cleaning mechanism is further arranged on the base 1. The cleaning mechanism can clean the drill bit when the drilling mechanism drives the drill bit support 2 to move away from the base 1.

[0046] In this embodiment, the drill bit support 2 is used to fix the drill bit and drive the drill bit to rotate at a high speed, and the drill bit is always perpendicular to the base 1. The base 1 is used to fix the material to be processed; the drill bit support 2 is driven to slide on the cross bar 6 through the horizontal positioning mechanism so that the drill bit is aligned with the processing position of the material to be processed.

[0047] After that, the cross bar 6 is driven to gradually approach the base 1 through the drilling mechanism so that the drill bit can contact the surface of the material, and the drill bit rotates at a high speed to drill holes in the material. Since a large amount of drill chips will accumulate on the drill bit during the drilling process, when the drilling depth is relatively shallow, the high-speed rotating drill bit itself will discharge the drill chips; as the drilling depth gradually increases, the difficulty of discharging the drill chips by rotation will gradually increase; when the drilling is too deep, the undischarged drill chips will affect the drilling effect and reduce the drilling formability. And when the drill chips accumulate to a certain extent, the service life of the drill bit will be greatly reduced.

[0048] In order to avoid the influence of drill chips on drilling, after the drilling mechanism drives the drill bit support 2 to approach the base 1 by a certain distance, it drives the drill bit support 2 to gradually move away from the base 1 until it returns to the initial position. During the process of moving away, the drill bit will use the rotational force to discharge a part of the drill chips; then it drives the drill bit support 2 to gradually approach the base 1, and the approaching distance will be larger than the previous time; after that, it drives the drill bit support 2 to move away from the base 1 to the initial position. By continuously performing operations of drilling, separating, drilling deeper, and separating again, the formability of the drilling can be enhanced while drilling the material.

[0049] After the drilling mechanism drives the drill bit support 2 to move away from the base 1 to a specific position (the position where the drill bit is separated from the drilling), the cleaning mechanism will blow air onto the drill bit to further clean the residual drill chips on the drill bit through the air flow, so as to further reduce the influence of the drill chips on drilling and enhance the drilling formability.

[0050] The drill bit is accurately positioned through the horizontal positioning mechanism; through the mutual cooperation of the drilling mechanism and the cleaning mechanism, the material can be drilled, the formability of the drilling is improved, and the damage of the drill bit during the drilling process is avoided, thereby increasing the production cost.

[0051] As a further solution of the present utility model, the horizontal positioning mechanism includes a second chute 601 opened on the cross bar 6, a lead screw 7 is rotatably installed in the second chute 601; an internal thread sleeve 14 that is in threaded cooperation with the lead screw 7 is slidably fitted in the second chute 601; the drill bit support 2 is fixedly installed on the internal thread sleeve 14.

[0052] In this embodiment, the lead screw 7 is rotated, and the internal thread sleeve 14 is driven to slide in the second chute 601 through the thread fit with the internal thread sleeve 14, so as to drive the drill bit support 2 to displace on the cross bar 6, thereby realizing the precise positioning of the drill bit. Since the movement of the drill bit support 2 is completed through the thread fit between the lead screw 7 and the internal thread sleeve 14, when the lead screw 7 stops rotating, the position of the drill bit support 2 will remain unchanged and is not affected by external interference factors, which can avoid the occurrence of inclined drilling or misaligned drilling when the drill bit is drilling due to the sudden change of the position of the drill bit support 2.

[0053] As a further scheme of the present utility model, the drilling mechanism includes a rotating shaft 3 rotatably installed on the base 1, a fitting groove 301 is formed on the rotating shaft 3, a slider 4 is slidably installed on the rotating shaft 3, a circular groove 401 is formed on the slider 4, and a protruding column 402 slidably fitted with the fitting groove 301 is fixedly installed in the circular groove 401; a first chute 102 is formed on the protective sleeve 101; a connecting block 5 fixedly connected with the cross bar 6 is fixedly installed on the slider 4, and the connecting block 5 is slidably fitted in the first chute 102.

[0054] In this embodiment, when the motor drives the rotating shaft 3 to rotate, the fitting groove 301 will rotate accordingly. At this time, the protruding column 402 will slide in the fitting groove 301; the inner wall of the fitting groove 301 will continuously squeeze the protruding column 402, thereby driving the slider 4 to slide on the rotating shaft 3; the connecting block 5 will slide in the first chute 102 synchronously with the movement of the slider 4, thereby driving the cross bar 6 to approach or move away from the base 1.

[0055] Since the drill bit rotates at a high speed on the drill bit support 2, when the cross bar 6 drives the drill bit support 2 to approach the base 1, the drill bit will contact the material to realize drilling.

[0056] As a further scheme of the present utility model, the fitting groove 301 is composed of a plurality of "V"-shaped notches connected; and the depth of each "V"-shaped notch increases in an arithmetic progression.

[0057] In this embodiment, when the protruding column 402 slides on the inclined upward section of the "V"-shaped notch, the slider 4 will slide downward on the rotating shaft 3; when the protruding column 402 slides on the inclined downward section of the "V"-shaped notch, the slider 4 will slide upward on the rotating shaft 3. Since the depth of each "V"-shaped notch is different, the lengths of the inclined upward section and the inclined downward section of each "V"-shaped notch are also different. When the protruding column 402 enters another "V"-shaped notch from one "V"-shaped notch, the final distance it approaches the base 1 is different. Through continuous operations of drilling, separating, deep drilling again, and separating again, the forming degree of the drilled hole can be enhanced while drilling the material.

[0058] As a further solution of the present utility model, the cleaning mechanism includes a piston cylinder 8 fixedly installed at one end of the protective sleeve 101 away from the base 1; a piston 10 is slidably fitted in the piston cylinder 8, a connecting rod 11 fixedly installed on the piston 10 and slidably connected to the piston cylinder 8, a connecting frame 12 fixedly installed at one end of the connecting rod 11 away from the piston 10, and the connecting frame 12 is slidably fitted with the rotating shaft 3, and the connecting frame 12 can cooperate with the slider 4; a spring 13 is wound around the connecting rod 11, and both ends of the spring 13 are respectively in contact with the piston cylinder 8 and the connecting frame 12; the piston cylinder 8 is fixedly communicated with a conduit 9.

[0059] In this embodiment, when the protruding column 402 slides in the fitting groove 301 to cause the slider 4 to rise, so that the drill bit rises with the drill bit support 2 until it is separated from the drill hole, the slider 4 will push the connecting frame 12 to slide on the rotating shaft 3 in a direction away from the base 1, thereby pushing the connecting rod 11 to drive the piston 10 to slide inward in the piston cylinder 8, and the spring 13 will be compressed; the air in the piston cylinder 8 will be compressed as the piston 10 slides; the conduit 9 and the piston cylinder 8 are fixedly communicated through a pressure relief valve. After the gas in the cylinder is compressed to a specific value, the pressure relief valve will open, so that the high-pressure gas in the cylinder is blown out from the conduit 9, thereby further cleaning and discharging chips from the drill bit, so as to further reduce the influence of drill chips on the drill hole and enhance the drill hole forming degree.

[0060] As a further solution of the present utility model, a nozzle 15 is fixedly installed at one end of the conduit 9 away from the piston cylinder 8, and the angle of the nozzle 15 is adjustable.

[0061] In this embodiment, by adjusting the angle of the nozzle 15, the air outlet of the nozzle 15 is aligned with the drill bit, so as to avoid reducing the cleaning ability of the cleaning mechanism when the sizes of the drill bits installed on the drill bit support 2 are different.

[0062] As a further solution of the present utility model, a handle is fixedly installed on the lead screw 7, and an anti-slip groove is provided on the handle.

[0063] In this embodiment, turning the lead screw 7 through the handle is more labor-saving, and the anti-slip groove can reduce the probability of slipping when turning the handle.

[0064] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of the present utility model, all technical solutions that can implement the present utility model in other specific forms are included in the present utility model.
