Description

Technical Field

[0001] The utility model belongs to the field of drilling machinery, in particular to an inclined hole drilling machine for drilling inclined holes on profiles. Background Art

[0002] Electric drills have a wide range of applications, encompassing a variety of fields, including machinery, construction, and marine mining. Currently, most electric drills on the market are single-bit drilling machines, and only a few studies have examined row drilling machines that can simultaneously drill multiple holes in profiles. For example, the row drilling machine disclosed in Chinese patent document CN102825290A comprises a base, two brackets on the base, and a cross brace and a cross beam disposed at the bottom and top of the brackets, respectively. The electric drill support is connected to a guide tube mounted on the cross beam, and a number of electric drills are mounted on the electric drill support. The guide tube drives the electric drill support to move up and down. A horizontal workpiece processing table is provided on the cross brace below the electric drill bit, and the workpiece to be processed is placed on the workpiece processing table. When the row drilling machine is in use, the piston rod of a hydraulic cylinder is extended and retracted, driving the electric drill support and the electric drill 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 setting can only drill rows of vertical holes. However, the use of the workpiece to be drilled and the installation methods between components in life are diverse. For example, some workpieces need to be drilled with holes at a certain inclined angle to the surface or busbar, and some need to drill vertical holes on arc-shaped or arched workpieces. These holes are not perpendicular to the profile surface. These inclined or arched workpieces to be drilled are drilled in rows, or horizontal workpieces to be drilled are drilled at an angle, etc. The existing row drilling machine cannot perform multi-hole inclined drilling on the above-mentioned workpieces to be drilled simultaneously. If a single drill bit is used for inclined hole drilling operations, it is not only inefficient, but also inaccurate measurement during the inclined drilling operation can easily cause the drill holes to be offset, affecting the precision of the workpiece to be drilled, which is not conducive to the use of components and the installation between components. The scrap rate of the workpiece to be drilled is high, which is neither economical nor environmentally friendly. Therefore, there is a need for an inclined hole row drilling machine that can perform multi-hole inclined drilling operations on the workpiece to be drilled at the same time. Utility Model Content

The fixture for clamping the workpiece to be drilled on the workbench is non-horizontally arranged, so that the workpiece to be drilled forms a required drilling angle with the axial direction of the inclined hole drill bit after clamping. The distances between different inclined hole drills or their drill bit tips and the clamped workpiece to be drilled are consistent so that all drill bits can drill holes in the workpiece to be drilled; the relative movement of the inclined hole drill and the workbench up and down is achieved by a lifting mechanism and a guide mechanism connected to the inclined hole drill or the workbench, which drives the inclined hole drill or the workbench to move up and down and is controlled by the control mechanism.

[0007] A further improvement of the technical solution of the present utility model is that a displacement device for controlling the lateral displacement of the workbench is provided between the workbench and the operating beam. The displacement device includes one or both of a pneumatic displacement device and a manual displacement device. A limit bolt for limiting the lateral displacement distance of the workbench is provided on one side of the operating beam.

[0009] A further improvement of the technical solution of the present invention is that the non-horizontal arrangement of the fixtures includes the connection lines of the fixtures forming a curve or a curved surface, or forming an inclined straight line or a plane.

[0010] A further improvement of the technical solution of the present utility model is that: when the fixture is not set horizontally to a curve or a curved surface, the line connecting the ends of the inclined hole drilling bits also forms the same curve or curved surface angle; when the non-horizontal surface of the fixture is set to an inclined straight line or plane, the inclination of the line connecting the ends of the inclined hole drilling bits is consistent with the inclination of the straight line or plane.

[0011] A further improvement of the technical solution of the present utility model is that the clamp includes a plurality of pads and stoppers arranged along the length direction of the workbench and a tightening device arranged at both ends of the workbench for supporting the workpiece to be drilled.

[0012] A further improvement of the technical solution of the present utility model is that the tightening device includes a positioning bolt located at one end of the workbench for limiting and adjusting the position of the workpiece to be drilled and a tightening cylinder located at the other end.

[0034] The present invention is further described in detail below with reference to the embodiments:

[0035] Example 1

[0036] like Figure 1 As shown, this embodiment provides an inclined hole drilling machine, including an inclined hole drill 8 and a workbench 6. The inclined hole drill 8 and the workbench 6 are arranged correspondingly up and down and can move relative to each other. The relative movement of the inclined hole drill 8 and the workbench 6 is controlled by a control mechanism, and the operation and stopping of the inclined hole drill 8 are also controlled by the control mechanism. The inclined hole drill 8 includes several drill bits 8-1, and a fixture for clamping the workpiece 14 to be drilled is non-horizontally arranged on the workbench 6. The non-horizontally arranged fixture enables the clamped workpiece 14 to be at an angle to the axis of the drill bit of the inclined hole drill 8, which is exactly the angle required for drilling. The distances between different inclined hole drills 8 or their drill bit tips and the clamped workpiece 14 to be drilled are consistent, so that during the rising process of the workpiece 14 to be drilled driven by the workbench 6, all drill bits can drill holes on the workpiece 14 to be drilled. The consistency here does not mean that the distance between the drill bit and the workpiece is exactly the same, but means that the distance between the inclined hole drill 8 or its drill bit tip and the clamped workpiece 14 to be drilled tends to be roughly the same, so that corresponding holes can be drilled on the workpiece 14 to be drilled. The upper surface of the workbench 6 can be set to match the shape of the workpiece 14 to be drilled, or a number of support rods can be set to make its upper surface match the shape of the workpiece 14 to be drilled. The relative up and down movement of the inclined hole drill 8 and the workbench 6 can be achieved by the lifting mechanism 5 and the guide mechanism connected to the inclined hole drill 8 or the workbench 6. The lifting mechanism 5 and the guide mechanism are controlled by the control mechanism to drive the inclined hole drill 8 or the workbench 6 to move up and down relative to each other.

[0037] The fixtures can be arranged non-horizontally on the workbench 6 to suit the shape of the workpiece 14 to be drilled. For example, the lines connecting the fixtures can form a curve or surface, an inclined straight line or plane, or a wavy line or surface. For example, if the workpiece 14 to be drilled is a curved strip after installation and a row of holes needs to be drilled along its length, the fixtures can be arranged in the shape of a curve that matches the installed curve. If the workpiece 14 to be drilled is a curved plate, if more than two rows of holes need to be drilled in the horizontal and vertical directions or across the entire plate surface, this can be achieved by moving the fixtures longitudinally inward or outward, or by arranging the inclined hole drills 8 into multiple rows in parallel. This approach can also be used when drilling holes in workpieces of other shapes.

[0038] During drilling, the control mechanism controls the lifting mechanism 5 and the guide mechanism to cause the worktable 6 or the inclined hole drill 8 to move relative to each other, so that the workpiece 14 to be drilled on the worktable 6 contacts the drill bit of the inclined hole drill 8 to perform the drilling operation. The control mechanism includes a control box that controls the operation of the inclined hole drill 8, the lifting mechanism 5, and the guide mechanism. The control box is equipped with a motor and a transmission mechanism that drives the inclined hole drill 8. The inclined hole drill 8 can be controlled uniformly by the motor and transmission mechanism, or each drill bit of each inclined hole drill 8 can be equipped with an independent motor. The control box is equipped with operating switches that control the operation of each electrical device.

[0039] Example 2

[0040] like Figure 2-Figure 7 As shown, the structure of the inclined hole drilling machine provided in this embodiment, the inclined hole drilling machine and the plurality of drill bits, the control mechanism, the lifting mechanism, the workbench, and the connection method between the various components are exactly the same as those in Example 1, except that:

[0041] The guide mechanism includes guide columns 9 provided on both sides of the base 1 and guide tubes 9-2 cooperating with the guide columns 9. The guide tubes 9-2 can move up and down along the guide columns 9. The workbench 6 is provided on the operating beam 6-2 and is connected to the guide tubes 9-2 on both sides through the ends of the operating beam 6-2. The operating beam 6-2 is driven up and down by the lifting mechanism 5 installed on the base 1. The inclined hole drill 8 is provided above the workbench 6 and is fixedly supported by the pillars 2 provided on both sides of the base 1. When the operating switch is turned on and the lifting mechanism 5 is activated to drive the operating beam 6-2 up and down, the guide tubes 9-2 at both ends of the operating beam 6-2 move up and down synchronously along the guide columns 9, so that the operating beam 6-2 drives the workbench 6 to move up and down. The lifting mechanism 5 can be two symmetrically arranged lifting cylinders or electric cylinders, or other devices with lifting functions.

[0042] When the fixture is not set horizontally to form a curve or a curved surface, the line connecting the ends of the drill bits of the inclined hole drill 8 also forms the same curve or curved surface angle. When the middle part of the curve or curved surface formed by the fixture connecting lines bends downward, the workpiece 14 to be drilled is placed on the fixture, and the extended length of the drill bits of the inclined hole drill 8 decreases from the middle to both sides. The curvature of the line connecting the ends of the drill bits of the inclined hole drill 8 and the curvature of the curve or curved surface formed by the fixture connecting lines are not limited.

[0043] In order to facilitate the replacement of the drilling position, a displacement device for controlling the lateral displacement of the workbench 6 is provided between the workbench 6 and the operating beam 6-2. The displacement device can be one or both of a pneumatic displacement device 10 and a manual displacement device 11, or other devices with a displacement function. A limiting bolt 6-3 is provided on one side of the operating beam 6-2 to limit the lateral displacement distance of the workbench 6. The distance between the limiting bolt 6-3 and the workbench 6 is the distance for changing the hole position.

[0044] The pneumatic displacement device 10 includes a cylinder 10-1 and a pneumatic displacement switch 10-2 which are laterally arranged on the operating beam 6-2. One end of the cylinder 10-1 is fixedly connected to the operating beam 6-2 through a triangular steel so that it is parallel to the position of the workbench 6. The piston rod end of the other end of the cylinder 10-1 is fixedly connected to the workbench 6. When the pneumatic displacement switch 10-2 is turned on, the cylinder 10-1 starts and converts the pressure of the compressed air into mechanical energy through pneumatic transmission. The piston rod of the cylinder 10-1 drives the workbench 6 to perform a lateral displacement movement relative to the operating beam 6-2, so that the workpiece to be drilled 14 on the fixture follows the displacement of the workbench 6, thereby changing the drilling position.

[0045] Manual displacement device 11 includes a rack 11-1 mounted on workbench 6 and a gear 11-2 mounted on operating beam 6-2 and meshing with rack 11-1. A crank 11-3, which rotates gear 11-2, is fixedly connected to the center of gear 11-2. During operation, crank 11-3 is gripped to rotate gear 11-2. Gear 11-2 meshes with rack 11-1, and the power transmitted by gear 11-2 to rack 11-1 drives workbench 6 to move laterally, thereby changing the drilling position. Both displacement devices can change the drilling position. Pneumatic displacement device 10 is more labor-efficient than manual displacement device 11. However, if pneumatic displacement device 10 becomes damaged, it can be repaired while manual displacement device 11 is used to change the hole position, ensuring smooth drilling operations.

[0046] The fixture is provided with several pads 7-1 and stops 7-2 along the length of the workbench 6, and may also be provided with several recessed slots. During drilling, the workpiece 14 to be drilled is placed on the pad 7-1 between the stops 7-2, and the several stops 7-2 on both sides limit the displacement of the workpiece 14 to be drilled in the width direction. A tightening device for supporting the workpiece 14 to be drilled is provided at both ends of the workbench 6. The tightening device includes a positioning bolt 12 located at one end of the workbench 6 and a tightening cylinder 13 located at the other end of the workbench 6. During drilling, the tightening cylinder 13 cooperates with the positioning bolt 12 to limit and adjust the left and right displacement of the workpiece 14 to be drilled. The positioning bolt 12 can be adjusted in length by screwing to accommodate workpieces 14 to be drilled of various lengths.

[0047] Since a large amount of dust is generated during drilling, the pad 7-1 and the block 7-2 of the fixture are arranged in the groove on the upper surface of the workbench 6. A plurality of slag discharge holes are opened at the bottom of the groove, and a dust collecting device 7-3 is connected below the slag discharge holes. A large amount of dust and slag generated during drilling accumulate in the groove of the workbench 6. After drilling is completed, the dust and slag can be collected into the dust collecting device 7-3 to ensure the environmental hygiene of the operation workshop. The dust collecting device 7-3 can be a dust collecting bag or a dust suction equipment or other device with a dust collection function.

[0048] At least two stabilizing devices 15 are arranged above the workpiece 14 to be drilled. The stabilizing device 15 includes two retractable spring rods 15-1 and stabilizing blocks 15-2 connected to the ends of the spring rods 15-1 and capable of pressing the workpiece 14 to be drilled. The two spring rods 15-1 are arranged on both sides of the drill bit 8-1 of the inclined hole drill 8. When drilling, the workbench 6 rises, the stabilizing blocks 15-2 contact the workpiece 14 to be drilled, the springs on the spring rods are compressed, and the stabilizing blocks 15-2 press the workpiece 14 to be drilled, thereby avoiding the problem of displacement and bulging of the workpiece 14 to be drilled.

[0049] During drilling, the workpiece 14 to be drilled is placed in the fixture of the workbench 6, so that one end of the workpiece 14 contacts the positioning bolt 12. The operating switch is turned on, the lifting mechanism 5 is activated, and the operating beam 6-2 moves upward along the guide columns 9 at both ends, so that the workpiece 14 to be drilled approaches the inclined hole drilling 8. The inclined hole drilling 8 is activated, and the motor transmits kinetic energy to the several drill bits 8-1 of the inclined hole drilling 8 through multiple meshing gears in the control box and the transmission belt. When the drill bits 8-1 contact the workpiece 14 to be drilled, the inclined drilling operation is performed. During the drilling process, the other end of the workpiece 14 to be drilled is tightened by the tightening cylinder 13, and its surface is pressed by the stabilizing device 15. After drilling is completed, the lifting mechanism 5 descends, and the operating beam 6-2 moves downward along the guide columns 9 at both ends, so that the workpiece 14 to be drilled on the workbench 6 is away from the inclined hole drilling 8. If the hole position needs to be changed, the pneumatic displacement switch 10-2 needs to be activated. The air pressure generated by the compressed air in the cylinder 10-1 is converted into mechanical energy to enable the piston rod to drive the workbench 6 to move horizontally relative to the operating beam 6-2 to the limit bolt 6-3, so that the hole position of the workpiece 14 to be drilled is changed, and then the above drilling steps are repeated to perform the operation. The position change can also be adjusted through the manual displacement device 11.

[0050] Example 3

[0051] like Figure 8 As shown, the structure of the inclined hole drilling machine provided in this embodiment and the connection method between the components are the same as those in Example 2, except that:

[0052] When the fixture is not set horizontally to form a curve or a curved surface, the line connecting the ends of the drill bits of the inclined hole drill 8 also forms the same curve or surface angle. When the middle part of the curve or surface formed by the fixture lines bends upward, the workpiece 14 to be drilled is placed on the fixture, and the extended length of the drill bits of the inclined hole drill 8 increases successively from the middle to both sides. The curvature of the line connecting the ends of the drill bits of the inclined hole drill 8 and the curvature of the curve or surface formed by the fixture lines are not limited.

[0053] Example 4

[0054] like Figure 9 As shown, the structure of the inclined hole drilling machine provided in this embodiment and the connection method between the components are the same as those in Example 2, except that:

[0055] The connecting lines of the fixtures form an inclined straight line or plane, and the inclination of the connecting lines of the drill bits of the inclined hole drill 8 is consistent with the inclination of the straight line or plane. When the straight line or plane formed by the connecting lines of the fixtures is tilted to one side, there is a certain angle with the horizontal direction. The workpiece 14 to be drilled is placed on the fixture at an angle, and the extended length of the drill bit of the inclined hole drill 8 changes accordingly to one side in accordance with the inclination of the fixture. The inclination of the connecting lines of the drill bits of the inclined hole drill 8 and the inclination of the straight line or plane formed by the connecting lines of the fixtures are not limited.

[0056] Example 5

[0057] like Figure 10 As shown, the structure of the inclined hole drilling machine provided in this embodiment and the connection method between the components are the same as those in Example 2, except that:

[0058] The connecting lines of the fixtures form an inclined straight line or plane, and the inclination of the connecting line of the drill bit ends of the inclined hole drill is consistent with the inclination of the straight line or plane. When the straight line or plane formed by the connecting lines of the fixtures is inclined to both sides in an X-shaped arrangement, there is a certain angle between the two sides and the horizontal direction. The workpiece 14 to be drilled is placed on the fixture, and the extended length of the drill bit of the inclined hole drill 8 increases successively from the middle to both sides. The inclination of the connecting line of the drill bit ends of the inclined hole drill 8 and the inclination of the straight line or plane formed by the connecting lines of the fixtures are not limited.

[0059] Example 6

[0060] like Figure 11 As shown, the structure of the inclined hole drilling machine provided in this embodiment and the connection method between the components are the same as those in Example 2, except that:

[0061] The connecting lines of the fixtures form an inclined straight line or plane, and the inclination of the connecting line of the drill bit ends of the inclined hole drill is consistent with the inclination of the straight line or plane. When the straight line or plane formed by the connecting lines of the fixtures is inclined to both sides in an inverted eight-shaped arrangement, there is a certain angle between the two sides and the horizontal direction. The workpiece 14 to be drilled is placed on the fixture, and the extended length of the drill bit of the inclined hole drill 8 decreases from the middle to both sides. The inclination of the connecting line of the drill bit ends of the inclined hole drill 8 and the inclination of the straight line or plane formed by the connecting lines of the fixtures are not limited.

[0062] The above embodiments only list several forms of inclined hole drilling machines, which are not exhaustive. If the workpiece 14 to be drilled is of other non-horizontal shapes, corresponding fixtures and inclined hole drills 8 can be designed according to needs, which all fall within the scope of protection of the present utility model.

[0063] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
