Description

Technical Field

[0001] The invention relates to the technical field of valve processing, in particular to a radial drilling machine for valve processing which is convenient for positioning. Background Art

[0002] In valve production, drilling is usually done by radial drilling machines. A radial drilling machine is a drilling machine with a rocker that can rotate and rise and fall around a column, and the spindle box usually moves horizontally on the rocker. The radial drilling machine can be aligned by moving the tool axis, which greatly facilitates the processing of holes on large and heavy workpieces in single-piece and small-batch production.

[0003] When drilling holes in valves using a radial drilling machine, workers need to align the drill bit and the hole to be processed with the naked eye. However, there is a height difference between the drill bit and the valve before drilling, and the drop point of the drill bit cannot be accurately judged by naked eye observation, resulting in frequent deviations in the drilling point, making the valve prone to misalignment and insufficient locking during subsequent installation, affecting the sealing effect. In view of this, we propose a radial drilling machine for valve processing that is easy to position. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 7The present invention provides a radial drilling machine for valve processing that is easy to position, including a base 1 and a column 2 installed on the base 1, a guide rail 3 is installed on the surface of the column 2, the column 2 can rotate relative to the base 1, and the guide rail 3 can move up and down relative to the column 2, so that the drilling position can be flexibly adjusted. Secondly, it also includes a control box 4, the control box 4 is slidably installed on the guide rail 3, and a drilling mechanism 5 is arranged in the control box 4. The drilling mechanism 5 includes a drill bit 53 for drilling. The base 1, the column 2, the guide rail 3, the control box 4 and the drill bit 53 constitute the basic structure of the radial drilling machine, which can meet the basic requirements of radial drilling.

[0032] Before the formal drilling, the position of the drill bit 53 needs to be calibrated. The traditional method is to judge it manually with the naked eye. However, there is a height difference between the drill bit 53 and the valve before drilling. The falling point of the drill bit 53 cannot be accurately judged by naked eye observation, resulting in deviations in the drilling point. This makes the valve prone to misalignment and insufficient locking during subsequent installation, affecting the sealing effect.

[0033] To this end, the radial drilling machine also includes a positioning mechanism 6, which is arranged on the control box 4 and is used to locate the drilling center and the hole size.

[0034] Specifically, the positioning mechanism 6 includes a laser emitting module 62, which emits lasers to locate the hole position. There are no less than two laser emitting modules 62, and no less than two laser emitting modules 62 are distributed in a circular array around the axis of the drill bit 53, and the emitting end of the laser emitting module 62 is tilted toward one side of the axis of the drill bit 53, so that no less than two laser beams converge at one point on the axis of the drill bit 53, and by adjusting the height of the laser intersection point, the intersection point coincides with the center point of the valve hole position mark, which can ensure that the drill bit 53 and the hole position are on the same vertical line.

[0035] In a preferred embodiment, the laser emitted by the laser emission module 62 meets the Class 1 laser in the international laser safety standard IEC60825-1. This type of laser has low power and will not cause harm to the human body if viewed directly for a long time, thereby improving the operational safety of the staff.

[0036] In one embodiment, the positioning mechanism 6 further includes a supporting component 61 , and the supporting component 61 is used to support the laser emitting module 62 to ensure the stability of the laser emitting module 62 .

[0037] See also Figure 4The support component 61 includes a fixed ring plate 611 fixedly mounted on the outside of the control box 4, the inner periphery of the fixed ring plate 611 is fixedly connected to the control box 4, and a plurality of fixed frames 612 are fixedly mounted on the outer periphery of the fixed ring plate 611, and one end of the fixed frame 612 is rotatably connected to the laser emitting module 62 through a rotating shaft 613. The laser emitting module 62 can be rotated relative to the fixed ring plate 611, so that the laser emission angle can be changed, so that the laser moves from the center of the valve hole mark to the outer circumference of the hole, so that the drilling area can be positioned during the drilling process to avoid the deviation of the drilling point.

[0038] In one embodiment, the positioning mechanism 6 further includes an adjusting component 63, which is used to synchronously adjust the laser emission angles of the multiple laser emission modules 62, so that after the laser emission angles are changed, the multiple laser beams can still converge at one point on the axis of the drill bit 53.

[0039] Please combine Figure 6 and Figure 7 As shown, the adjustment component 63 includes a slide rod 634 slidably mounted on the fixed ring plate 611, the axis of the slide rod 634 is parallel to the axis of the drill bit 53, and can move up and down relative to the fixed ring plate 611, the bottom end of the slide rod 634 passes through the fixed ring plate 611 and is fixedly mounted with a movable ring plate 635, the movable ring plate 635 is coaxially arranged with the drill bit 53, and an annular tooth groove 6351 is opened on the outer peripheral wall of the movable ring plate 635, the number of the annular tooth grooves 6351 is plural, and the multiple annular tooth grooves 6351 are equidistantly distributed along the axial direction thereof. The movable ring plate 635 is meshed with multiple transmission gears 636 through the annular tooth groove 6351. The multiple transmission gears 636 are respectively fixedly installed on the multiple rotating shafts 613. When the movable ring plate 635 moves up and down, the multiple transmission gears 636 can be synchronously driven to rotate through meshing transmission. The transmission gears 636 synchronously drive the multiple laser emission modules 62 to rotate through the rotating shaft 613, thereby realizing synchronous adjustment of multiple laser emission angles to ensure that the laser intersection point will not deviate from the axis of the drill bit 53.

[0040] In one embodiment, the top of the slide bar 634 passes through the control box 4 and is fixedly mounted with a driving plate 633. The up and down movement of the driving plate 633 can synchronously control the up and down movement of the movable ring plate 635. There are no less than two slide bars 634. Figure 6 An implementation method in which the number of the sliding bars 634 is three is given, and the three sliding bars 634 are distributed in a triangle, thereby improving the stability of the movement of the driving plate 633 and the movable ring plate 635.

[0041] For driving purposes, the adjustment component 63 also includes a support frame 631 fixedly mounted on one side of the control box 4, on which a linear drive module 1 632 is mounted, and the support frame 631 is used to provide support for the linear drive module 1 632, which is an electric cylinder or a linear module, and can achieve relatively precise linear control. The output end of the linear drive module 1 632 is connected to the drive plate 633 to provide a driving force for the movable ring plate 635 to move up and down.

[0042] In one embodiment, an indicating component is provided on one of the slide bars 634. The indicating component includes a pointer 637 and a scale 31. The pointer 637 is fixedly mounted on the slide bar 634. The scale 31 is provided on one side of the guide rail 3. When the slide bar 634 moves downward, the pointer 637 is synchronously driven to move downward. By observing the scale 31 corresponding to the pointer 637, the movement amplitude of the movable ring plate 635 can be observed. In the repetitive work of drilling holes with the same aperture, the time required for adjustment can be reduced, thereby improving work efficiency.

[0043] See also Figure 3 The drilling mechanism 5 also includes a linear drive module 2 51 installed in the control box 4. The linear drive module 2 51 is an electric cylinder or a linear module, which can realize relatively precise linear control. The output end of the linear drive module 2 51 passes through the bottom end of the control box 4 and is provided with a rotary motor 52. The output end of the rotary motor 52 is connected to the drill bit 53 for driving the drill bit 53 to rotate at high speed to realize drilling.

[0044] Furthermore, a sleeve 55 is fixedly mounted on the rotating motor 52, a guide rod 54 is slidably mounted on the inner wall of the sleeve 55, the top end of the guide rod 54 is fixedly mounted on the control box 4, and there are multiple sleeves 55 and guide rods 54 to improve the stability of the up and down movement of the drill bit 53 and avoid the drill bit 53 from deflecting.

[0045] See also Figure 2 The radial drilling machine also includes a clamping and fixing mechanism 7, which is arranged on the base 1 and is used to fix the valve.

[0046] When the radial drilling machine for valve processing that is easy to position of the present invention is used, the valve with the hole mark engraved is fixed on the base 1 through the clamping and fixing mechanism 7, so that the side with the hole mark faces directly upward. Before drilling, each laser emitting module 62 is started for positioning, and the lasers emitted by each laser emitting module 62 are gathered at one point. The positions of the drilling mechanism 5 and the positioning mechanism 6 are adjusted through the coordination of the basic structures of the radial drilling machine such as the column 2, the guide rail 3 and the control box 4, so that the laser intersection point coincides with the center of the hole mark. At this time, the drill bit 53 and the hole mark are on the same vertical line, and the drill bit 53 can be lowered to drill.

[0047] Before drilling, in order to improve the drilling accuracy, the linear drive module 1 632 can be started first. The output end of the linear drive module 1 632 drives the driving plate 633 to move downward. The driving plate 633 drives the movable ring plate 635 to move downward through the slide bar 634. The movable ring plate 635 drives multiple transmission gears 636 to rotate through the annular tooth groove 6351 opened thereon. The transmission gear 636 drives the laser emission module 62 to rotate a certain angle through the rotating shaft 613, so that the laser beam moves outward relative to the hole position mark center. The laser beam forms a circle outside the mark center to show the area to be drilled. When drilling, the rotary motor 52 drives the drill bit 53 to rotate at a high speed, and the linear drive module 2 51 controls the drill bit 53 to move downward to drill the preset area. If there is no deviation during drilling, the drilling area will not exceed the area surrounded by the laser. By observing the drilling position, the judgment of the drilling accuracy can be improved to ensure the accuracy of the drilling.

[0048] During the movement of the slide bar 634, the pointer 637 will be driven to move synchronously. By recording the scale 31 indicated by the pointer 637, the control efficiency of the up and down movement range of the movable ring plate 635 can be improved. In the repetitive work of drilling holes with the same aperture, the time required for adjustment can be reduced and the work efficiency can be improved.
