Description

Technical Field

[0001] The utility model belongs to the field of drilling machinery, in particular to a drilling machine for drilling holes in different directions of profiles. Background Art

[0002] Drilling equipment, such as electric drills, has a wide range of applications, encompassing a variety of fields, including machinery, construction, and marine mining. Currently, most electric drills on the market are either single-bit drills or multiple-bit drills that form clusters or nests of holes within a processing surface. There are only a few studies on row drills that can simultaneously drill multiple holes in profiles, and even fewer on row drills capable of drilling over a hundred holes. For example, the row drill disclosed in Chinese patent document CN102825290A comprises a base, two brackets on the base, and a cross brace and a crossbeam located at the bottom and top of the brackets, respectively. The brackets are vertically provided with mutually cooperating guide rods and guide tubes. An electric drill support is connected to the guide tubes, and several electric drills are mounted on the electric drill support. The guide tubes drive the electric drill support to move up and down. A horizontal workpiece processing table is provided on the cross brace below the drill bits, and the workpiece to be processed is placed on the workpiece processing table. During use, the row drill is driven by the piston rod of a hydraulic cylinder, which extends and retracts, driving the electric drill support and the electric drills to move up and down, completing the drilling of multiple holes at once. Another example is a device for automatically drilling multiple holes in plastic parts disclosed in Chinese patent document CN106914954A, which includes a control structure, a frame, a lifting platform sliding in the vertical direction, a horizontal workpiece fixing structure arranged on the lifting platform, a multi-axis drilling structure arranged on the upper part of the frame, and a lifting cylinder arranged on the frame for driving the lifting platform to slide up and down. The parts to be processed are placed on the workpiece fixing structure. The multi-axis drilling structure is equipped with multiple vertical drill bits side by side in the left and right directions, and is synchronously driven by 1-3 motors. The multi-axis drilling structure is located directly above the workpiece fixing structure. This technology completes drilling by driving the workpiece up and down through the lifting platform.

[0003] Although the row drilling machine in the above-mentioned prior art can perform multi-hole drilling operations simultaneously, saving manpower and improving accuracy, its structure can only drill rows of vertical holes in one direction. However, some parts need to have vertical holes and horizontal holes at the same time, such as a long-span fiberglass anti-glare net crossbar used on the central isolation belt of the highway. It not only needs many vertical holes in the length direction of the crossbar, but also needs to have several horizontal holes perpendicular to the vertical holes at both ends of the crossbar. Using the existing drilling equipment, if you want to drill both vertical holes and horizontal holes on the parts, you need to pause the equipment and then manually rotate the workpiece to be drilled. This operation not only easily leads to inaccurate measurement and offset of the drilling, but also affects the precision of the workpiece to be drilled, which increases the scrap rate of the workpiece to be drilled. Therefore, there is a need for a row drilling machine that can perform vertical and horizontal bidirectional vertical drilling of the workpiece to be drilled in rows. Utility Model Content

[0009] A further improvement of the technical solution of the present utility model is that the workbench or the fixture moves left and right to several hole positions, or moves forward and backward to several work positions, which is achieved by cooperating with a displacement device installed between the workbench and the operating beam supporting the workbench, or installed between the workbench and the fixture. The displacement device includes one or both of a pneumatic displacement device and a manual displacement device; and limiting bolts are respectively provided in each displacement direction of the workbench or the fixture.

[0010] A further improvement of the technical solution of the present utility model is that: the pneumatic displacement device includes a cylinder and a pneumatic displacement switch, and the cylinder is arranged between the operating beam and the workbench or between the workbench and the fixture; the manual displacement device includes a screw rod and a nut sleeve that are threaded together or a rack and a gear that are meshed with each other, and the rack and the gear or the nut sleeve and the screw rod are installed in cooperation between the workbench and the operating beam or between the fixture and the workbench; the displacement device that moves forward and backward is arranged in at least two groups evenly spaced in the left and right length directions of the workbench.

DETAILED DESCRIPTION

[0031] The present invention is further described in detail below with reference to the embodiments:

[0032] Example 1

[0033] like Figure 1As shown, this embodiment provides a bidirectional vertical drilling machine, including a workbench 1 carrying a workpiece 4 to be drilled, a vertical hole drill 2 capable of vertically drilling holes on the workpiece 4 to be drilled, and a horizontal hole drill 3 capable of horizontally drilling holes on the workpiece 4 to be drilled. The horizontal hole drill 3 is arranged in front and back correspondence with the workbench 1, and the workbench 1 is arranged in top and bottom correspondence with the vertical hole drill 2. The horizontal hole drill 3 can be provided with several drill bits along the length direction of the workpiece 4 to be drilled, or two or three drill bits can be provided at both ends of the workpiece 4 to be drilled, and can be adaptively adjusted according to the drilling requirements. The operation and stopping of the vertical hole drill 2 and the horizontal hole drill 3 are controlled by a control mechanism. The vertical hole drill 2 and the horizontal hole drill 3 are equipped with several drill bits controlled by the control mechanism, and the drill bits of the two can cooperate with each other but do not interfere with each other. The worktable 1 is connected to a guide mechanism and, driven by a drive mechanism, moves up and down toward the vertical hole drill 2. The horizontal hole drill 3, connected to it, moves forward and backward toward the worktable 1 via the guide mechanism and drive mechanism. The horizontal hole drill 3, along with its guide mechanism and drive mechanism, can move up and down integrally with the worktable 1. The drive mechanism is controlled by a control mechanism and, under its control, cooperates with the guide mechanism to achieve the up and down movement of the worktable 1 and the horizontal hole drill 3. Under the control of the control mechanism, the vertical and horizontal drilling operations are completed in rows on the workpiece 4 to be drilled.

[0034] During drilling, the control mechanism controls the drive mechanism to drive the worktable 1 upward relative to the vertical hole drill 2 along the guide mechanism, and the horizontal hole drill 3 forward relative to the worktable 1, so that the workpiece 4 to be drilled, carried by the worktable 1, contacts the drill bits of the vertical hole drill 2 and the horizontal hole drill 3, respectively, to perform the drilling operation. The control mechanism includes a control box that controls the operation of the vertical hole drill 2, the horizontal hole drill 3, and the drive mechanism. The control box is equipped with a motor and transmission mechanism that drives the vertical hole drill 2 and the horizontal hole drill 3. The drill bits of the vertical hole drill 2 and the horizontal hole drill 3 can be controlled uniformly by the motor and transmission mechanism, or each drill bit can be equipped with an independent motor. The control box is equipped with operating switches that control the operation of each electrical device.

[0035] Example 2

[0036] like Figure 2-Figure 7 As shown, the present embodiment provides a bidirectional vertical drilling machine, wherein the structures of the vertical hole drilling machine, the horizontal hole drilling machine, the plurality of drill bits, the workbench, the control mechanism, the drive mechanism, and the connection method between the components are exactly the same as those in the first embodiment, except that:

[0037] The guide mechanism can be one of the guide rails 5 or the guide tube column structure, or it can be other structures with a guiding function. The guide tube column structure includes a guide column 6 and a guide tube 7 that cooperate with each other. The guide tube 7 can move up and down along the guide column 6. The workbench 1 is set on the operating beam 8 and is connected to the guide tube 7 through the two ends of the operating beam 8. The operating beam 8 is driven by a driving mechanism installed at the bottom of the operating beam 8 to move up and down. The vertical hole drill 2 is set above the workbench 1 and is fixedly supported by pillars 9 arranged on both sides, thereby realizing the vertical hole drill 2 and the workbench 1 relative movement up and down. However, the structural design for realizing the relative movement between the vertical hole drill 2 and the workbench 1 is not unique. The vertical hole drill 2 can also be connected to the guide tube 7 to realize the vertical hole drill movement up and down toward the workbench under the drive of the driving mechanism. The horizontal hole drill 3 is fixedly supported by a bracket 10 provided on one side of the workbench 1. The bracket 10 and the workbench 1 are integrally structured. Several horizontal hole drills 3 or their drill bits can be provided along the length of the workpiece 4 to be drilled, or one or more can be provided at each end of the workpiece 4 to be drilled. The number of horizontal hole drills 3 can be adjusted adaptively according to drilling requirements. The horizontal hole drill 3 is connected to the bracket 10 via guide rails 5 provided on both sides of the bracket 10. The forward and backward movement of the horizontal hole drill 3 is driven by a drive mechanism mounted on the bracket 10 and controlled by a control mechanism. The drive mechanism can be a hydraulic cylinder, an electric cylinder, or a meshing gear and rack, or other device with a driving displacement function.

[0038] Several rows of fixtures are installed on the workbench 1. Each row of fixtures includes multiple slots. The multiple slots of each row of fixtures are arranged in sequence along the left and right directions of the machine tool. Each row of fixtures can hold a workpiece 4 to be drilled of a certain shape and size. A row of fixtures corresponds to a station for holding parts. The shape or size of the slots of two adjacent rows of fixtures can be the same or different. The workbench 1 or the fixtures can be moved left and right by several hole positions or forward and backward by several stations relative to the vertical hole drill 2 and the horizontal hole drill 3. These rows of fixtures are set in a long strip-shaped groove 1-1. When the fixture is required to move left and right by several hole positions or forward and backward by several stations, the groove 1-1 drives all the fixtures to move together.

[0039] Each slot is composed of a pad 1-2 and two stops 1-3. The shape and size of each slot for clamping a workpiece of a certain type matches the shape and size of the workpiece 4 to be drilled. A row of slots with the same shape and size constitutes a fixture for clamping a certain workpiece. The specifications, shape, and spacing of the pads 1-2 and stops 1-3 in each row can be adaptively adjusted according to the type of workpiece 4 to be drilled, thereby adapting to workpieces 4 of different shapes to be drilled. Of course, the above-mentioned pads 1-2 and stops 1-3 can also be replaced with other components with equivalent functions. During drilling, the workpiece 4 to be drilled is supported by the several pads 1-2 located below it, while the several stops 1-3 on both sides limit the displacement of the workpiece 4 to be drilled. It should be noted that although the pads 1-2 and stops 1-3 constitute a slot, the position of the pads 1-2 relative to the stops 1-3 can be staggered left and right, which will not affect drilling and chip removal.

[0040] The workbench 1 is moved left and right by several hole positions or forward and backward by several workstations relative to the vertical and horizontal drilling machines 2 and 3 by a displacement device installed between the workbench 1 and the operating beam 8 supporting the workbench 1. If the fixture as a whole is moved left and right by several hole positions or forward and backward by several workstations relative to the vertical and horizontal drilling machines 2 and 3, this can also be achieved by a displacement device installed between the workbench 1 and the groove 1-1. The displacement devices controlling the forward and backward movement are arranged in at least two groups evenly spaced along the left and right length of the workbench 1.

[0041] The displacement device can be one or both of a pneumatic displacement device 11 and a manual displacement device 12, or other devices with displacement functions. A limiting bolt 8-1 is respectively provided in each displacement direction of the workbench 1 or the fixture. Taking the left and right movement direction of the workbench 1 as an example, a limiting bolt 8-1 for limiting the lateral displacement distance of the workbench 1 can be provided on one side of the operating beam 8. The distance between the limiting bolt 8-1 and the workbench 1 is the distance of the conversion hole position. The limiting bolt 8-1 can be set accordingly for other displacement directions according to operational requirements. For example, a corresponding limiting bolt 8-1 can be set on the workbench 1 for the forward and backward movement direction of the fixture.

[0042] The following example illustrates the arrangement of the pneumatic displacement device and the manual displacement device, taking the example of the workbench 1 being able to move left and right relative to the vertical hole drill 2 and the horizontal hole drill 3 to several hole positions:

[0043] The pneumatic displacement device 11 includes a cylinder 11-1 and a pneumatic displacement switch 11-2. The cylinder 11-1 is arranged between the operating beam 8 and the workbench. When the cylinder 11-1 is arranged between the operating beam 8 and the workbench, one end of the cylinder 11-1 is fixedly connected to the operating beam 8 by a triangular steel so that it is parallel to the position of the workbench 1. The piston rod end of the other end of the cylinder 11-1 is fixedly connected to the workbench 1. When the pneumatic displacement switch 11-2 is turned on, the cylinder 11-1 is started, and the pressure of the compressed air is converted into mechanical energy through pneumatic transmission. The piston rod of the cylinder 11-1 drives the workbench 1 to move horizontally to the left and right relative to the operating beam 8, so that the workpiece 4 to be drilled on the fixture moves left and right with the workbench 1, thereby changing the drilling position. When the fixture is set to be able to move left and right to several hole positions relative to the vertical hole drill 2 and the horizontal hole drill 3, the cylinder 11 is arranged between the workbench 1 and the groove 1-1. Their connection method can refer to the above-mentioned structural setting.

[0044] The manual displacement device 12 is provided between the operating beam 8 and the workbench 1. When the manual displacement device 12 is provided between the operating beam 8 and the workbench 1, the manual displacement device 12 includes a screw and a nut sleeve that are threadedly matched with each other, or a rack 12-1 and a gear 12-2 that mesh with each other. To set the rack 12-1 and the gear 12-2 that mesh with each other, in detail, when the rack 12-1 is provided on the workbench 1 and the gear 12-2 that meshes with the rack 12-1 is provided on the operating beam 8, the center of the gear 12-2 is fixedly connected to a crank 12-3 that rotates the gear 12-2. During operation, the gear 12-2 is rotated by gripping the crank 12-3, and the gear 12-2 meshes with the rack 12-1. The rack 12-1 is driven by the power transmitted by the gear 12-2 to drive the workbench 1 to move laterally, thereby changing the drilling position. When the fixture is configured to be movable left and right by several hole positions relative to the vertical hole drill 2 and the horizontal hole drill 3 , the manual displacement device 12 is disposed between the workbench 1 and the groove 1 - 1 , and can be configured in the same manner as described above.

[0045] Both pneumatic and manual displacement devices can change the drilling position. The pneumatic displacement device 11 saves more manpower than the manual displacement device 12. However, when the pneumatic displacement device 11 is damaged, it can be repaired while the manual displacement device 12 is used to change the hole position to ensure smooth drilling operation.

[0046] For example, the fixture can be moved forward and backward relative to the vertical hole drill 2 and the horizontal hole drill 3 to determine several hole positions:

[0047] A manual displacement device 12 is provided between the groove 1-1 and the workbench 1. The manual displacement device 12 can be configured as a screw and nut sleeve that engage with each other in a threaded manner, or as a rack 12-1 and gear 12-2 that mesh with each other. The groove 1-1 is fixedly connected to the nut sleeve. The nut sleeve is provided with a screw driven by a motor that engages with each other in a threaded manner. The screw and nut sleeve are provided in at least two evenly spaced groups. The groove 1-1 drives the fixture forward and backward on the workbench 1 through the interlocking screw, nut sleeve, and slide rails; or it drives the fixture forward and backward on the workbench 1 through the interlocking gear, rack, and slide rails. The gear and rack are provided in at least two evenly spaced groups. When the workbench 1 is configured to be able to move forward and backward to a plurality of hole positions relative to the vertical hole drilling 2 and the horizontal hole drilling 3, the manual displacement device 12 is provided between the workbench 1 and the operating beam 8 and can be configured in the same manner as described above.

[0048] Both ends of the groove 1-1 are provided with a clamping device for supporting the workpiece 4 to be drilled, thereby positioning the workpiece 4. The clamping device includes a positioning bolt 13 located at one end of the groove 1-1 to limit and adjust the position of the workpiece 4 to be drilled, and a clamping cylinder 14 located at the other end of the workbench 1. During drilling, the workpiece 4 to be drilled is placed on the spacer 1-2 between the stoppers 1-3. The clamping cylinder 14 cooperates with the positioning bolt 13 to limit the left and right displacement of the workpiece 4 to be drilled. The positioning bolt 13 can be adjusted in length by screwing to accommodate workpieces 4 of various lengths.

[0049] Since a large amount of dust is generated during drilling, a plurality of slag discharge holes may be provided at the bottom of the groove 1-1, and a dust collecting device is connected below each of the slag discharge holes. A large amount of dust and slag generated during drilling accumulate in the groove 1-1. After drilling is completed, the dust and slag may be collected into the dust collecting device to ensure the environmental hygiene of the operation workshop. The dust collecting device may be a dust collecting bag or a dust suction device or other device with a dust collecting function.

[0050] At least two flexible stabilizing devices 15 are provided above the workpiece 4 to be drilled. The stabilizing devices 15 include a retractable spring rod 15-1 and a stabilizing block 15-2 connected to the spring end of the spring rod 15-1 and capable of pressing the workpiece 4 to be drilled. There may be two spring rods 15-1, and the stabilizing blocks 15-2 are connected to the two spring rods 15-1. When the stabilizing blocks 15-2 press the workpiece 4 to be drilled, the stabilizing blocks 15-2 can move up and down along the rod bodies of the spring rods 15-1 under the action of the springs. The two spring rods 15-1 are provided on either side of the drill bit of the vertical hole drill 2. The diameter of the spring rod 15-1 is smaller than the distance between two adjacent drill bits of the corresponding horizontal hole drill 3. The width of the stabilizing block 15-2 is smaller than the distance between two adjacent drill bits of the corresponding vertical hole drill 2. This prevents the stabilizing device 15 from affecting the drilling functions of the vertical hole drill 2 and the horizontal hole drill 3 when pressing the workpiece 4 to be drilled. When drilling, the stabilizing block 15-2 follows the vertical hole drill 2 to contact the workpiece 4 to be drilled, the spring on the spring rod is compressed, and the stabilizing block 15-2 presses the workpiece 4 to be drilled, avoiding the problem of deviation and bulging of the workpiece 4 to be drilled during the drilling operation.

[0051] When performing vertical and horizontal drilling operations, the workpiece 4 to be drilled can be placed on the fixture so that one end of the workpiece 4 to be drilled contacts the positioning bolt 13, the other end is tightened by the tightening cylinder 14, and its surface is pressed by the stabilizing device 15.

[0052] Example 3

[0053] like Figure 8 As shown, the bidirectional vertical drilling machine provided in this embodiment has the same structure and connection method of the components as those in Example 1 except for the vertical hole drilling machine, the horizontal hole drilling machine, and the connection method of the workbench and the guide mechanism. The difference is:

[0054] The vertical hole drill 2 is connected to the guide mechanism and is driven by the driving mechanism to move up and down toward the workbench 1. The horizontal hole drill 3 is connected to the guide mechanism and is driven by the driving mechanism to move forward and backward toward the workbench 1. The vertical hole drill 2 is arranged on the corresponding guide column 6 through the guide tube 7 connected thereto, and is driven up and down by the driving mechanism installed on the guide tube 7. The workbench 1 is correspondingly arranged below the vertical hole drill 2 and is arranged on an operating beam 8 with a fixed support component at the bottom. The workbench 1 is fixed and stationary. The horizontal hole drill 3 is fixedly supported by a bracket 10 arranged on one side of the workbench 1. The bracket 10 and the workbench 1 can be an integrated structure or two independent structures. The horizontal hole drill 3 is arranged on the bracket 10 through the guide rail 5 and is driven by the driving mechanism installed on the bracket 10, thereby realizing the forward and backward movement of the horizontal hole drill 3 relative to the workbench 1.

[0055] Example 4

[0056] The present embodiment provides a bidirectional vertical drilling machine, in which the structures of the vertical hole drilling machine, the horizontal hole drilling machine, the plurality of drill bits, the workbench, the control mechanism, the drive mechanism, and the connection method between the various components are exactly the same as those in Example 3. The difference is that: the workbench 1 is provided with a plurality of rows of clamps including a plurality of slots, the displacement device between the workbench 1 and the operating beam 8 and between the groove 1-1 and the workbench 1, the tightening device, the dust collecting device, and the stabilizing device 15. The structures of the above components and the connection relationship between them and other components are the same as those in Example 2.

[0057] The following details the process of horizontal and vertical drilling:

[0058] After the drilling is completed, the driving mechanism drives the workbench 1 to move downward and removes the first workpiece 4 to be drilled that has completed drilling. Then the fixture is adjusted to move forward and backward under the action of the manual displacement device 12, driving the second workpiece 4 to be drilled to a position suitable for drilling, and the vertical hole drill 2 and the horizontal hole drill 3 drill the second workpiece 4 to be drilled again, and so on. After the drilling of all the workpieces 4 to be drilled is completed, the operating beam 8 moves downward along the guide columns 6 at both ends under the drive of the driving mechanism, so that the workbench 1 returns to its original position.

[0059] If the hole position needs to be changed, the pneumatic displacement switch 11-2 needs to be activated. The air pressure generated by the compressed air in the cylinder 11-1 is converted into mechanical energy to enable the piston rod to drive the workbench 1 to move horizontally relative to the operating beam 8 to the limit bolt 8-1, so that the hole position of the workpiece 4 to be drilled is changed, and then the above drilling steps are repeated to perform the operation.

[0060] The utility model can be applied to the drilling operation of the cross bars and ribs of the highway anti-glare net. The isolation rods and ribs, upper cross bars and lower cross bars of the highway anti-glare net are an interlaced structure. The ribs, upper cross bars and lower cross bars are all provided with holes. The isolation rods are passed through the holes on the upper cross bar, lower cross bar and ribs. In order to facilitate the combined installation between the above-mentioned components, it is necessary to drill corresponding and uniform vertical holes that are compatible with the isolation rods along the length direction of the cross bars and ribs. Since the cross bar needs to be connected to the vertical bars and columns on both sides through tees and crosses, it is also necessary to drill horizontal holes that are compatible with the tees and crosses at both ends of the cross bar.

[0061] When processing anti-glare net parts, the fixture of the drilling machine can be set as follows Figure 7 In the two rows shown, the pads 1-2 and the stoppers 1-3 of the two rows of fixtures are respectively configured to fit the shapes of the crossbars and the ribs. During the drilling operation, the cross bar and ribs that need to be drilled are respectively mounted on the two rows of fixtures, the cross bar is mounted on the inner fixture close to the cross hole drill 3, and the ribs are mounted on the outer fixture, and the workbench 1 is driven to move to a position suitable for horizontal and vertical drilling, and the manual displacement device 12 is adjusted to move the ribs to the bottom of the vertical hole drill 2, and the workbench 1 is continued to be driven upward to contact the vertical hole drill 2 so that the vertical hole drill 2 drills a number of evenly spaced vertical holes on the ribs. After the vertical drilling is completed, the workbench 1 is driven downward, and the manual displacement device 12 is adjusted to move the cross bar to the bottom of the vertical hole drill 2, and the workbench 1 is continued to be driven upward to contact the vertical hole drill 2 so that the vertical hole drill 2 drills a number of evenly spaced vertical holes corresponding to the ribs on the cross bar. At this time, the cross hole drills 3 arranged at both ends of the workbench 1 move forward to contact the cross bar and drill a suitable number of evenly spaced cross holes at both ends of the cross bar.
