Description

Technical Field

[0001] The utility model relates to the technical field of metal product production, in particular to a radial drilling machine used for metal product production. Background Art

[0002] A radial drilling machine is a drilling machine with a rocker arm that can rotate and rise and fall around a column. Usually, the spindle box moves horizontally on the rocker arm. When machining holes on a vertical drilling machine, the alignment of the tool and the workpiece is achieved by moving the workpiece, which is obviously very inconvenient for some large and heavy workpieces. However, a radial drilling machine can use the position of the moving tool axis for alignment, which greatly facilitates the machining of holes on large and heavy workpieces in single-piece and small-batch production.

[0003] Most of the existing radial drilling machines control the drilling mechanism to slide up and down along the outside of the rotating shaft by driving the threaded rod to rotate by a motor. However, since the center of gravity of the drilling mechanism is not located at the center line of the rotating shaft, the contact position between the drilling mechanism and the rotating shaft is subjected to force for a long time, which may cause deformation after long-term use, resulting in uneven sliding of the drilling mechanism up and down along the outside of the rotating shaft, affecting the normal use of the radial drilling machine. Therefore, a radial drilling machine for metal product production is proposed to solve the above problem. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] The utility model aims to solve the problem that most of the existing radial drilling machines control the drilling mechanism to slide up and down along the outer side of the rotating shaft by driving the threaded rod to rotate by a motor, but since the center of gravity of the drilling mechanism is not located at the center line of the rotating shaft, the position where the drilling mechanism contacts the rotating shaft is subjected to force for a long time, which may cause deformation after long-term use, resulting in uneven sliding of the drilling mechanism up and down along the outer side of the rotating shaft, affecting the normal use of the radial drilling machine, and thus a radial drilling machine for metal product production is proposed.

[0006] (II) Technical solution

[0007] The technical solution of the utility model to solve the above technical problems is as follows:

[0008] A radial drilling machine for metal product production comprises a base, a drilling pad is fixedly connected to the top of the base, a hole slot is formed on the drilling pad, a rotating seat is fixedly connected to the top of the base, a rotating shaft is rotatably connected to the inner side of the rotating seat, a first clamping assembly is arranged on the outer side of the rotating seat, a second clamping assembly is arranged on the outer side of the rotating shaft, a mounting cross arm is fixedly connected to the second clamping assembly, a threaded rod for moving up and down is threadedly connected to the inner side of the mounting cross arm, a steering gear is fixedly connected to the top of the rotating shaft, a servo motor is fixedly connected to the input end of the steering gear, the threaded rod for moving up and down is fixedly connected to the bottom end of the output end of the steering gear, and a drilling mechanism is arranged on the mounting cross arm;

[0009] The second tightening assembly includes a second tightening sleeve, the outer side of the rotating shaft is provided with a second tightening sleeve, the second tightening sleeve is in an unclosed loop shape, the left end of the second tightening sleeve is fixedly connected to two second ear blocks, the inner side of the second ear block on the front side is threadedly connected to a second threaded rod with one end penetrating and extending to the inner side of the second ear block on the rear side, the second threaded rod is fixedly connected to a second rotating handle, and the mounting cross arm is fixedly connected to the right end of the second tightening sleeve.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

If the contact position between the second clamping sleeve and the rotating shaft is deformed after the radial drilling machine is used for a long time, the second rotating handle can be rotated in the opposite direction to make the second threaded rod disengage from the second ear block at the rear side, and then another staff member tightens the second clamping sleeve to make the relative distance between the two second ear blocks smaller, and then the second rotating handle is rotated to make the second threaded rod enter the inner side of the second ear block to tighten the rotating shaft.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0018] In the embodiment, Figure 1 A radial drilling machine for metal product production is provided, comprising a base 1, a drilling pad 2 is fixedly connected to the top of the base 1, a hole groove 3 is opened on the drilling pad 2, a rotating seat 4 is fixedly connected to the top of the base 1, a rotating shaft 5 is rotatably connected to the inner side of the rotating seat 4, a first clamping assembly 6 is arranged on the outer side of the rotating seat 4, a second clamping assembly 7 is arranged on the outer side of the rotating shaft 5, a mounting cross arm 8 is fixedly connected to the second clamping assembly 7, an up-and-down moving threaded rod 9 is threadedly connected to the inner side of the mounting cross arm 8, a steering gear 10 is fixedly connected to the top of the rotating shaft 5, a servo motor 11 is fixedly connected to the input end of the steering gear 10, the up-and-down moving threaded rod 9 is fixedly connected to the bottom end of the output end of the steering gear 10, and a drilling mechanism 12 is arranged on the mounting cross arm 8;

[0019] The second tightening assembly 7 includes a second tightening sleeve 71, the outer side of the rotating shaft 5 is sleeved with the second tightening sleeve 71, the second tightening sleeve 71 is in an unclosed loop shape, the left end of the second tightening sleeve 71 is fixedly connected to two second ear blocks 72, the inner side of the second ear block 72 on the front side is threadedly connected to a second threaded rod 73 with one end penetrating through and extending to the inner side of the second ear block 72 on the rear side, the second threaded rod 73 is fixedly connected to a second rotating handle 74, and the mounting cross arm 8 is fixedly connected to the right end of the second tightening sleeve 71.

[0020] With the above arrangement, during normal operation, first a staff member rotates the second rotating handle 74 in the opposite direction to disengage the second threaded rod 73 from the second ear block 72 at the rear side, and then tightens the second tightening sleeve 71 with both hands. Then another staff member rotates the second rotating handle 74 to allow the second threaded rod 73 to enter the inner side of the second ear block 72 to tighten the rotating shaft 5, and opens the first tightening assembly 6 so that it no longer tightens the rotating seat 4. The rotating shaft 5 is rotated until the drilling mechanism 12 moves to the top of the drilling pad 2 and aligns the drill bit with the hole groove 3. The first tightening assembly 6 is then used to tighten the rotating seat 4 to limit the displacement of the rotating shaft 5. The servo motor 11 is started, and the power is transmitted to the up and down moving threaded rod 9 through the steering gear 10, so that the mounting cross arm 8 moves upward or downward along the rotating shaft 5 to a suitable position. The metal product to be processed is then placed above the drilling pad 2, and the drilling mechanism 12 is started to drill the metal product. The second clamping mechanism 71 is a commonly used mechanism used in existing radial drilling machines, which is common knowledge among technicians in the relevant technical field, and therefore will not be described in detail.

[0021] Reference Figure 1 , wherein the first clamping assembly 6 comprises a first clamping sleeve 61, the outer side of the rotating seat 4 is sleeved with the first clamping sleeve 61, the first clamping sleeve 61 is in an unclosed loop shape, the front end of the first clamping sleeve 61 is fixedly connected with two first ear blocks 62, the inner side of the first ear block 62 on the right side is threadedly connected with a first threaded rod 63 having one end penetrating and extending to the left side of the first ear block 62 on the left side, and the first threaded rod 63 is fixedly connected with a first rotating handle 64;

[0022] With the above-mentioned structural arrangement, a staff member rotates the first rotating handle 64 in the opposite direction to disengage the first threaded rod 63 from the first ear block 62 on the left side, and then tightens the first tightening sleeve 61 with both hands. Another staff member rotates the first rotating handle 64 to allow the first threaded rod 63 to enter the inner side of the first ear block 62 on the left side, thereby tightening the rotating seat 4 and limiting the displacement of the rotating shaft 5. It should be noted that the rotating seat 4 is a deformable metal material. When the first tightening sleeve 61 tightens the rotating seat 4, the rotating seat 4 will expand inward, making the rotating seat 4 and the rotating shaft 5 in closer contact, thereby limiting the displacement of the rotating shaft 5 through friction.
