Description

Technical Field

[0001] The present invention relates to the technical field of machining equipment, and particularly to a fully automatic drilling machine for workpiece drilling. Background Art

[0002] A drilling machine refers to a general term for machinery and equipment that uses a tool harder and sharper than the target object to leave a cylindrical hole or cavity on the target object by means of rotary cutting or rotary extrusion. It is also known as a drilling machine, punching machine, eyelet machine, through-hole machine, etc. By drilling precision parts, the expected effect can be achieved. There are semi-automatic drilling machines and fully automatic drilling machines. The fully automatic drilling machine includes a drilling mechanism, three automatic traveling mechanisms in the X, Y, and Z directions that form a three-dimensional coordinate system, a workpiece clamping tooling and other components. It can complete the entire punching operation process according to the program or instruction set by the controller, which greatly improves the engineering quality and efficiency. And with the increase of human resource costs, most enterprises consider the fully automatic drilling machine as the development direction. However, when the fully automatic drilling machine used in current machining processes a workpiece, it usually uses direct spray water cooling. Although it can achieve the effect of cooling the workpiece, it is inevitable that the coolant will splash everywhere in the working environment, pollute the environment and is also prone to slipping production accidents. Moreover, since the cutting end of the drill bit is conical, when machining some workpieces that require through-hole machining, it is necessary to increase the drilling depth. Although this method can achieve the machining purpose, during the reciprocating machining process of the workpiece clamping tooling, holes of different depths will be drilled on its top structure, and the service life will be greatly shortened.

[0007] Preferably, the interior of the composite cooling box includes a cooling box body. A cooling groove is formed inside the inner side of the top of the cooling box body. The depth value of the cooling groove is equal to two-thirds of the height value of the cooling box body.

[0008] Preferably, a small blower is arranged inside the inner side of the middle part of the cooling box body. The bottom of the small blower is fixedly connected to the top of the tooling base. The air outlets of the small blower are respectively provided with a first composite cooling pipe fitting and a second composite cooling pipe fitting.

[0009] Preferably, the interior of the first composite cooling pipe fitting includes a first air duct. One end of the first air duct is fixedly sleeved with the air outlet of the small blower.

[0014] 1.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1 , a fully automatic drilling machine for workpiece drilling, including a machine body base 1, an X-axis traveling mechanism 10, a Y-axis traveling mechanism 11, a Z-axis traveling mechanism 12, a drilling mechanism 13, and a controller 14. The top of the machine body base 1 is respectively connected to the bottom of the Z-axis traveling mechanism 12 and the bottom of the X-axis traveling mechanism 10, and the top of the X-axis traveling mechanism 10 is connected to the bottom of the Y-axis traveling mechanism 11. The drilling mechanism 13 and the controller 14 are respectively installed on the front and one side of the top of the Z-axis traveling mechanism 12. A tooling base 2 is fixedly installed on the top of the Y-axis traveling mechanism 11. A composite adjustment mechanism 3 and a composite cooling box 5 are respectively connected to the top of the tooling base 2. The inside of the composite adjustment mechanism 3 includes a hollow sleeve plate 31 and a hydraulic rod 32. Both sides of the hollow sleeve plate 31 are fixedly connected with transition connecting frames, and the bottom of the transition connecting frame is connected to the top output end of the hydraulic rod 32. The bottom of the hydraulic rod 32 is fixedly installed on the top of the tooling base 2. While providing stable support for the subsequent components, the composite adjustment mechanism 3 also provides the working conditions for reciprocating lifting adjustment.

[0026] Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5, the composite cooling box 5 is snap-connected to the inner side of the middle part of the composite adjustment mechanism 3. The interior of the composite cooling box 5 includes a cooling box body 51, and a cooling groove 52 is provided on the inner side of the top of the cooling box body 51. The depth value of the cooling groove 52 is equal to two-thirds of the height value of the cooling box body 51. While the composite cooling box 5 can hold the coolant by itself, its own groove structure can also provide a self-cooling heat dissipation area for the coolant used repeatedly later. A small blower 7 is provided on the inner side of the middle part of the cooling box body 51, and the bottom of the small blower 7 is fixedly connected to the top of the tooling base 2. The air outlets of the small blower 7 are respectively equipped with a first composite cooling pipe fitting 8 and a second composite cooling pipe fitting 9. The small blower 7, as a blowing mechanism, provides working conditions for the air cooling of the subsequent workpiece and the self-cooling of the composite cooling box 5. The interior of the first composite cooling pipe fitting 8 includes a first air duct 81, and one end of the first air duct 81 is fixedly sleeved with the air outlet of the small blower 7. The other end of the first air duct 81 is fixedly connected to an L-shaped pipe 82, and a spray pipe 83 is fixedly sleeved inside the L-shaped pipe 82. An anti-interference groove is snap-connected to the outer side of the middle part of the first air duct 81, and the anti-interference groove is opened on the inner wall of one side of the hollow sleeve plate 31. The small blower 7 and the first composite cooling pipe fitting 8 are assembled together to form an air cooling mechanism. In addition to cooling the workpiece by air, it can also quickly pneumatically clean the waste chips drilled on the surface of the workpiece, avoiding secondary friction between the waste chips and the drill bit, and improving the drilling quality and the service life of the drill bit.

[0027] Please refer to Figure 1 , Figure 4 , the interior of the second composite cooling pipe fitting 9 includes a second air duct 91 and an annular pipe 92, and the annular pipe 92 is snap-connected inside the cooling groove 52. One end of the second air duct 91 penetrates through the inner wall of the cooling box body 51 in a fixed sleeved manner and extends to be fixedly sleeved inside one side of the annular pipe 92. After the second composite cooling pipe fitting 9 is assembled with the small blower 7, a ring-blowing type self-cooling mechanism can be formed, which can speed up the self-cooling speed of the coolant inside the composite cooling box 5 while making multiple uses of the small blower 7, and ensure the continuous cooling effect.

[0028] Please refer to Figure 1 , Figure 3 , the top of the composite adjustment mechanism 3 is connected with a composite hollow top seat 4.

An adjustment hole 42 is opened inside the hollow top plate 41. The bottom surface of the hollow top plate 41 is fixedly connected to the top surface of the hollow sleeve plate 31. The composite hollow top seat 4 provides guiding and limiting for the installation of the workpiece while drilling the workpiece.

[0029] Please refer to Figure 1 , Figure 4The interior of the composite hollow top seat 4 is clamped with a magnetic automatic fixing mechanism 6, and the bottom of the magnetic automatic fixing mechanism 6 is fixedly connected to the bottom of the tooling base 2. The interior of the magnetic automatic fixing mechanism 6 includes four small electromagnetic suction cups 61, and the four small electromagnetic suction cups 61 are all clamped in the inside of the adjustment hole 42. The bottoms of the four small electromagnetic suction cups 61 are all fixedly connected with a fixing rod 62, and the fixing rod 62 is fixedly connected to the top surface of the tooling base 2. After the tooling base 2, the composite adjustment mechanism 3, the composite hollow top seat 4, and the magnetic automatic fixing mechanism 6 are assembled together, an adjustable tooling is formed. Subsequently, when the tooling base 1 and the machine body base 1 are connected, The fully automatic drilling rig formed by the X-axis travel mechanism 10, the Y-axis travel mechanism 11, the Z-axis travel mechanism 12, the drilling mechanism 13 and the controller 14 has multiple states during the use. In the first state, the hole to be processed in the workpiece does not need to be penetrated, and the adjustable tooling only needs to provide stable support. In the second state, the hole to be processed in the workpiece needs to be penetrated. In the final processing of drilling, the composite adjustment mechanism 3 inside the adjustable tooling drives the composite hollow top seat 4 to make way and move, and the magnetic automatic fixing mechanism 6 performs a separate magnetic fixing. Therefore, while ensuring the smooth progress of the drilling process, the integrity of the tooling is maintained and the service life is extended.

[0030] See also Figure 1 , Figure 5 A pumping mechanism 15 and a reflux pipe are respectively arranged between the composite cooling box 5 and the composite hollow top seat 4. The pumping mechanism 15 includes a water pump inside, and both sides of the water pump are fixedly connected to the suction pipe and the infusion pipe, wherein one end of the suction pipe is fixedly connected to the inner side of the bottom of the cooling box body 51, and one end of the infusion pipe is fixedly sleeved on the inside of the hollow top plate 41. The composite cooling box 5, the pumping mechanism 15, and the composite hollow top seat 4 are assembled into a conductive cooling mechanism, and the small blower 7 and the first composite cooling pipe 8 are assembled into an air cooling mechanism. When the above two mechanisms are used in combination, the workpiece in the processing process can be double cooled, which fully improves the cooling effect while solving the problems caused by water cooling of traditional equipment and optimizes the processing procedure.

[0031] Working principle: When using, it is divided into multiple steps, which are described as follows;

[0032] Installation of the workpiece: Place the workpiece to be punched on the top surface of the hollow top plate 41 inside the composite hollow top seat 4, and the bottom surface of the workpiece is respectively fitted with the top surface of the hollow top plate 41 and the top surface of the small electromagnetic suction cup 61 inside the magnetic automatic fixing mechanism 6, and the two side surfaces of the workpiece are fitted with the inside of the L-shaped guide strip 43 for positioning and installation. After completion, start the small electromagnetic suction cup 61 inside the magnetic automatic fixing mechanism 6, and the small electromagnetic suction cup 61 magnetically fixes the workpiece to achieve automatic fixed installation;

[0033] For drilling the workpiece, input the coordinates of the hole inside the controller 14. The controller 14 controls the X-axis traveling mechanism 10 and the Y-axis traveling mechanism 11 respectively to perform horizontal displacement, so that the position of the workpiece to be drilled is aligned with the drill bit installed on the drilling mechanism 13. Then, the controller 14 starts the Z-axis traveling mechanism 12 and the drilling mechanism 13 to make the rotating drill bit perform drilling operations on the workpiece. Before the drilling operation starts, the water pump inside the pumping mechanism 15 can be started. The water pump automatically pumps the coolant in the coolant tank body 51 inside the composite cooling tank 5 to the hollow top plate 41 inside the composite hollow top seat 4 through the liquid suction pipe and the liquid delivery pipe connected to itself, and conducts heat dissipation to the workpiece through the hollow top plate 41. At the same time, start the small blower 7. The small blower 7 forcibly generates air flow and transports it to the inside of the first air delivery pipe 81 inside the first composite cooling pipe fitting 8, and then sprays it out through the nozzle 83 to perform air cooling on the workpiece. While performing air cooling, quickly pneumatically clean the waste chips drilled on the surface of the workpiece to avoid secondary friction between the waste chips and the drill bit;

[0034] When it is necessary to perform through drilling on the workpiece, according to the depth of the drill bit drilling displayed by the controller 14, in the final stage of drilling, close the hydraulic rod 32 inside the composite adjustment mechanism 3. The hydraulic rod 32 drives the hollow sleeve plate 31 and the composite hollow top seat 4 to move down and make way, so as to avoid the drill bit contacting the composite hollow top seat 4;

[0035] While the small blower 7 is operating, the air flow forcibly generated by the small blower 7 will be transported to the inside of the annular pipe 92 through the second air delivery pipe 91 inside the second composite cooling pipe fitting 9, and then sprayed out from the air spray holes 93 to perform air cooling treatment on the coolant tank body 51.
