Description

Technical Field

[0001] The invention relates to the technical field of drilling and tapping, and in particular to a drilling and tapping device. Background Art

[0002] Drilling and tapping equipment for mechanical processing is an important part of modern manufacturing. They use rotary cutting technology to accurately drill and tap metal or non-metallic materials. This device can not only perform drilling operations, but also perform various processing such as tapping, meeting the one-stop processing needs of complex workpieces.

[0003] During the process of tapping a workpiece, the device usually sprays cooling oil to the tapping position of the workpiece. The cooling oil can not only reduce the friction between the tapping head and the workpiece, but also cool the tapping head and the workpiece. After searching, a Chinese patent with a publication number of CN111299721B discloses a tapping spray device and a tapping device, wherein the tapping spray device includes: a protrusion and a spray mechanism; the protrusion is arranged on the lifting arm of the tapping device, and the spray mechanism is located on one side of the lifting arm, which includes: a crank, a roller and a liquid tank, the crank is pivotally connected to one side of the liquid tank, and the roller is pivotally connected to the crank At one end of the handle, the protrusion touches the roller as the lifting arm rises and falls, and drives the crank to pivot. The other end of the crank can squeeze the liquid tank as it pivots. The bottom of the liquid tank is connected to a liquid spray output pipe, and one end of the liquid spray output pipe extends to the tap connected to the lifting arm. The tapping liquid spray device proposed in the above scheme automatically sprays coolant or lubricant on the tap before and after tapping, which is beneficial to clear the metal debris remaining on the surface of the tap during the tapping process, and also plays a role in cooling and lubricating, which is beneficial to ensure the quality of the tapping of the workpiece or product. However, the above scheme still has the following shortcomings when it is actually used:

[0004] When the tapping device proposed in the above scheme processes a workpiece, the oil spraying action usually runs through the entire processing process of the workpiece. During the starting stage of the tapping head, the descending stage of the tapping head, the tapping stage and the resetting stage of the tapping head, the oil is always in a spraying state, and the oil spraying action cannot be synchronously controlled with the actual tapping action of the tapping head. This asynchronous oil spraying continues during the starting stage, the descending stage, the actual tapping stage and the resetting stage of the tapping head. Even when the tapping head has not yet contacted the workpiece, the oil continues to spray, which causes unnecessary waste of resources and increases production costs.

[0005] Therefore, the present application provides a drilling and tapping device. Summary of the invention

[0023] Beneficial effects of the present invention:

[0024] 1. The oil injection design adopted in the present invention brings many benefits. First, it effectively avoids unnecessary oil waste and improves the use efficiency of oil by accurately controlling the injection of oil. When the chuck is stationary, the oil is effectively blocked by the baffle to prevent ineffective loss of oil. When the chuck rotates, the baffle automatically staggers the opening under the action of centrifugal force, allowing the oil to be sprayed out on demand, realizing intelligent adjustment. Secondly, this system can intelligently adjust the oil injection amount according to the rotation speed of the chuck, meeting the needs of different working scenarios. In the initial stage of the chuck rotation, the oil injection amount is small; in the drilling and tapping stages, the oil injection amount increases accordingly to ensure cooling and lubrication effects; after the drilling and tapping are completed, the oil injection action also stops, further saving resources. In addition, the characteristics of on-demand injection and intelligent adjustment also reduce energy consumption and costs, and improve overall work efficiency.

[0025] 2. By introducing control valves on the two connecting pipes, the system achieves more sophisticated oil management. When the two chucks rotate synchronously, both oil nozzles have the ability to spray oil, but the staff can flexibly control the on-off state of the two connecting pipes through the two control valves. In the drilling stage, by closing the control valve on the connecting pipe corresponding to the tapping head, only the connecting pipe corresponding to the drilling head is opened to ensure that only the drilling head obtains the necessary cooling and lubricating oil, thereby avoiding the waste of oil in unnecessary areas. Similarly, in the tapping stage, by adjusting the state of the control valve, only the oil nozzle corresponding to the tapping head is sprayed, further improving the efficiency of oil use;

[0026] 3. The system effectively collects debris by allowing the oil in the spraying state to flow with the debris and flow into the box together. The two filter components set in the box adopt an innovative filtering method, that is, using a number of filter bars extending from the perforations to block the debris and allow the liquid oil to flow freely. This design makes the debris stuck on the filter bars, while the oil flows smoothly downward along the inclined fixed plate, achieving effective separation of oil and debris. This design avoids the problem of reduced separation efficiency caused by debris clogging of the traditional filter screen and ensures the separation effect of oil and debris.

[0027] 4. When it is necessary to clean the debris on the fixed plate, the staff can easily remove the fixed plate from the box body and pull the filter lever on it out of the perforation by pulling the movable plate. This step is simple and quick, and does not require complicated operations. As the filter lever is removed, the debris on the fixed plate can slide freely, which greatly facilitates the cleaning work of the staff and improves the cleaning efficiency;

[0028] 5. Through the principle of attraction between opposite poles and repulsion between like poles between magnetic blocks, the system can intelligently detect the oil accumulation state in the oil collection box, and automatically start or stop the circulation pump accordingly, without the need for manual monitoring and operation, greatly improving work efficiency and convenience. Secondly, the automated oil recovery process ensures the timely recycling of the oil, avoids waste and idleness of the oil, and improves resource utilization efficiency. Furthermore, the design effectively maintains the stability of the liquid level in the oil collection box by precisely controlling the timing of oil recovery, avoids oil overflow or over-extraction, and ensures the stable operation of the system. In addition, the oil is recovered after filtration and separation, which ensures the cleanliness of the recovered oil, extends the service life of the oil, and reduces replacement and maintenance costs.

DETAILED DESCRIPTION

[0043] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0045] like Figures 1 to 11 As shown, the present invention provides a drilling and tapping device, including a machine base 1, two oil injection units, a box body 7, a workpiece placement table 8, an oil filter unit and an oil recovery unit, the machine base 1 is equipped with a motor, the machine base 1 is also equipped with two rotatable chucks, both of which are driven by a motor, one of the chucks is equipped with a drilling head 2, and the other chuck is equipped with a tapping head 3, the box body 7 is assembled on the machine base 1, the workpiece placement table 8 is fixed on the box body 7, the top end of the box body 7 is open, and there is a gap between the workpiece placement table 8 and the inner wall of the box body 7; a gap is set on the workpiece placement table 8;

[0046] When the drilling and tapping equipment proposed by the present invention is used, the staff clamps the workpiece on the workpiece placement table 8 and starts the motor. When the motor is running, it drives the two chucks to rotate, so that the drilling head 2 and the tapping head 3 rotate. The staff can use the drilling head 2 to drill holes in the workpiece and use the tapping head 3 to tap the workpiece. It should be noted that the driving method of the motor for the two chucks is a prior art, which is not shown in the figure and will not be described in detail here.

[0047] like Figure 2 , Figure 3 , Fig.10As shown, the two oil injection units are both arranged on the machine base 1, and each of the oil injection units includes an oil supply component, a rotating component and an adaptive opening and closing component. The oil supply component includes an oil storage tank 41, an oil outlet cylinder 43, a connecting pipe 44, an oil spray pipe 45 and a connecting pipe 46. The oil storage tank 41 is fixed to the side of the machine base 1, and a downward pressing slide plate 42 is slidably arranged inside the oil storage tank 41. The oil outlet cylinder 43 is placed directly below the oil storage tank 41. One end of the connecting pipe 44 is connected to the oil storage tank 41, and the other end is connected to the oil storage tank 41. One end is connected with the oil outlet cylinder 43, the oil spray pipe 45 is connected with the oil outlet cylinder 43 through a connecting pipe 46, a control valve is installed on the connecting pipe 46, the rotating assembly includes a rotating shaft 51, a first gear 52 and a second gear 53, the rotating shaft 51 passes through the bottom of the oil outlet cylinder 43, and the rotating shaft 51 and the oil outlet cylinder 43 are rotatably connected, the first gear 52 is fixedly sleeved on one end of the rotating shaft 51 located outside the oil outlet cylinder 43, the second gear 53 is fixedly sleeved on the chuck, and the first gear 52 and the second gear 53 are meshed with each other;

[0048] like Figure 6 , Figure 7 As shown, the adaptive opening and closing component includes a rotating disk 61, four through-ports 62 and four shielding members. The rotating disk 61 is fixedly sleeved on one end of the rotating shaft 51 located inside the oil outlet cylinder 43. The outer peripheral surface of the rotating disk 61 and the inner surface of the oil outlet cylinder 43 fit each other. The four through-ports 62 are all opened on the rotating disk 61. The four shielding members are all arranged on the top surface of the rotating disk 61. The four shielding members are respectively arranged opposite to the four through-ports 62. The four shielding members and the four through-ports 62 are distributed in a circumferential array around the rotating shaft 51. The shielding members The parts include a baffle 63, a guide rod 64, a guide block 65 and a shielding member spring 66. The baffle 63 is arranged on the top surface of the rotating disk 61, and the baffle 63 is arranged opposite to the through-port 62. The guide rod 64 is fixed to the edge of the top surface of the rotating disk 61. The guide block 65 is fixed to the top surface of the baffle 63, and the guide block 65 is slidably sleeved on the guide rod 64. One end of the shielding member spring 66 is connected to the guide block 65, and the other end is connected to the guide rod 64. An end cap 67 is fixed to the end of the guide rod 64 close to the rotating shaft 51.

[0049] During the drilling and tapping process, the two oil injection units are in operation. Since the two oil injection units are exactly the same, a specific description is given here for any one of the oil injection units: cooling oil is stored in the oil storage tank 41, and a downward pressing slide 42 is slidably arranged in the oil storage tank 41. The downward pressing slide 42 is located above the cooling oil. Under the action of gravity, the downward pressing slide 42 always has a tendency to move downward, which enables the downward pressing slide 42 to press the oil into the oil outlet cylinder 43 through the connecting pipe 44. When the turntable 61 is in a stationary state, under the elastic force of the four shielding springs 66, the four guide blocks 65 are The four baffles 63 are respectively in contact with the four end caps 67. At this time, the four baffles 63 are respectively facing the four through openings 62 and blocking the four through openings 62, so that the oil cannot flow downward through the four through openings 62. When the chuck rotates, the chuck can drive the second gear 53 to rotate, so that the second gear 53 drives the first gear 52 meshing with it to rotate. When the first gear 52 rotates, it can drive the rotating shaft 51 to rotate, and the rotating disk 61 connected to the rotating shaft 51 will also rotate accordingly. During the rotation of the rotating disk 61, the baffle 63 can overcome the elastic force of the shielding spring 66 and the resistance of the cooling oil under the action of centrifugal force and move to the edge of the rotating disk 61. , which makes the four baffles 63 move synchronously and away from each other. In this process, the four baffles 63 will gradually stagger with the four through ports 62, and the oil accumulated above the turntable 61 will flow downward through the staggered positions of the baffles 63 and the through ports 62. Further, the oil will enter the oil nozzle 45 through the connecting pipe 46, and finally be sprayed out through the oil nozzle 45. Based on the above process, when the chuck is stationary, the oil is effectively blocked by the baffles 63 and cannot be sprayed out from the oil nozzle 45, thereby avoiding unnecessary waste of oil. When the chuck rotates, the baffles 63 automatically stagger the through ports 62 under the action of centrifugal force, allowing the oil to spray out, thereby achieving The oil injection is precisely controlled. In addition, the higher the rotation speed of the chuck, the greater the centrifugal force on the baffle 63, and the greater the degree of misalignment with the through-port 62, thereby increasing the amount of oil ejected, meeting the needs of different working scenarios. This on-demand injection and intelligent adjustment feature not only improves the efficiency of oil use, but also reduces energy consumption and costs. Specifically, in the initial stage of the chuck rotation, the transfer speed of the chuck is slow and the amount of oil injection is small. In the drilling and tapping stages, the chuck rotates at a high speed, and the amount of oil injection increases accordingly. After the drilling and tapping are completed, the chuck is reset and stops rotating, and the oil injection action also ends.

[0050] It is worth mentioning that control valves are installed on the two connecting pipes 46. According to the above principle, when the two chucks rotate synchronously, the two oil spray pipes 45 have a tendency to spray oil. Therefore, the staff can control the on-off of the two connecting pipes 46 through the two control valves. In the drilling stage, the staff controls the connecting pipe 46 corresponding to the tapping head 3 to be disconnected, and only the oil spray pipe 45 corresponding to the drilling head 2 is used to spray liquid. On the contrary, in the tapping stage, the staff controls the connecting pipe 46 corresponding to the drilling head 2 to be disconnected, and only the oil spray pipe 45 corresponding to the tapping head 3 is used to spray liquid. This can further avoid the waste of oil.

[0051] like Figure 4 , Figure 5 , Fig.11 As shown, the oil filter unit includes two filter assemblies, both of which are arranged inside the box 7 for separating oil and debris, and the filter assembly includes a fixed plate 91, a movable plate 92, four connecting pieces 93, a plurality of perforations 94 and a plurality of filter levers 95, the fixed plate 91 is placed inside the box 7, the movable plate 92 is arranged below the fixed plate 91, the fixed plate 91 and the movable plate 92 are connected by four connecting pieces 93, and the four connecting pieces 93 are respectively located at the four corners of the fixed plate 91. The connecting member 93 includes an outer frame, an inner plate and a connecting spring 96. The outer frame is fixed on the movable plate 92. The inner plate is slidably arranged in the outer frame. One end of the inner plate extends to the outside of the outer frame and is fixedly connected to the fixed plate 91. The outer frame and the inner plate are connected by a connecting spring 96. Several through holes 94 are provided on the fixed plate 91. Several filter levers 95 are fixed on the movable plate 92. Several filter levers 95 pass through several through holes 94 respectively. The fixed plate 91 and the movable plate 92 are both inclined.

[0052] During the drilling and tapping process, debris is also generated, and the oil in the spraying state can carry the debris and flow, and flow into the box body 7 through the gap between the box body 7 and the workpiece placement table 8 and the gap of the workpiece placement table 8. Two filter components are arranged inside the box body 7 for filtering and separating the oil and debris. Specifically, when the oil and debris fall on the fixed plate 91, the plurality of filter bars 95 extending from the plurality of perforations 94 can hinder the debris, so that the debris is stuck on the plurality of filter bars 95, while the liquid oil will not be blocked by the filter bars 95 and flows downward along the inclined fixed plate 91. Therefore, in the process of the oil and debris flowing along the fixed plate 91, the plurality of filter bars 95 can separate the oil and debris. This special structural design replaces the traditional method of using a filter to separate the oil and debris, and can avoid the situation where the debris blocks the filter, thereby ensuring the separation effect of the oil and debris.

[0053] When it is necessary to clean the debris on the fixed plate 91, the staff can remove the fixed plate 91 from the box body 7, and then pull the movable plate 92 to make the movable plate 92 away from the fixed plate 91. When the movable plate 92 moves, it can drive the plurality of filter levers 95 thereon to move, so that the plurality of filter levers 95 are pulled out from the plurality of perforations 94 until the plurality of filter levers 95 are all moved to the bottom of the fixed plate 91. Without the restriction of the plurality of filter levers 95, the debris accumulated on the fixed plate 91 can slide freely, which is convenient for the staff to quickly clean the debris collected on the fixed plate 91. It is clear that the fixed plate 91 and the movable plate 92 are connected by four connecting members 93, and the four connecting members 93 provide limit for the movement of the movable plate 92. Specifically, when the movable plate 92 moves, it can drive the outer frame to move, so that the outer frame and the inner plate move relative to each other. In addition, the connecting spring 96 arranged between the outer frame and the inner plate makes the movable plate 92 always have a tendency to approach the fixed plate 91. When the staff releases the movable plate 92, the movable plate 92 can automatically reset under the action of the four connecting springs 96, so that the plurality of filter levers 95 pass through the plurality of through holes 94 again.

[0054] like Figure 4 As shown, the two fixed plates 91 are inclined in opposite directions. In order to improve the separation effect of the device for oil and debris, two filter assemblies are arranged in the box 7, and the two fixed plates 91 in the two filter assemblies are inclined in opposite directions. When the oil and debris flow out from the upper fixed plate 91, the oil and debris will fall on the lower fixed plate 91, and the oil and debris will be separated again by the lower filter assembly. The setting of the two filter assemblies can separate the oil and debris twice to ensure the separation effect of the oil and debris.

[0055] like Figure 1 , Figure 4As shown, the oil recovery unit is arranged at the inner bottom of the box body 7, and the oil recovery unit is arranged below the oil filter unit. The oil recovery unit includes an oil collection component, a trigger component and a control component. The oil collection component includes an oil collection box 101, a circulation pump 102 and a three-way pipe 103. The oil collection box 101 is arranged at the inner bottom of the box body 7, and the top of the oil collection box 101 is open. The circulation pump 102 is installed on the side of the box body 7. The input end of the circulation pump 102 is connected to the oil collection box 101, and the output end of the circulation pump 102 is connected to one of the pipe openings of the three-way pipe 103. The other two pipe openings of the three-way pipe 103 are A return pipe 104 is connected, and one end of the two return pipes 104 away from the three-way pipe 103 is respectively connected to the two oil storage tanks 41. The trigger assembly includes a mounting seat 111, a first magnetic block 112 and a floating ball 115. The mounting seat 111 is fixed on the inner wall of the oil collection box 101, and the interior of the mounting seat 111 is hollow. The first magnetic block 112 is slidably arranged on the side of the mounting seat 111. Both ends of the first magnetic block 112 are fixed with a limiting frame 113. Two limiting grooves 114 are provided on the mounting seat 111. The two limiting frames 113 are respectively slidably arranged in the two limiting grooves 114. The floating ball 115 is connected to the first magnetic block 112 through a connecting rope;

[0056] like Figure 8 , Fig. 9 As shown, the control component includes a first conductive sheet 121, a second conductive sheet 122 and two second magnetic blocks 124, the first conductive sheet 121 is fixed inside the mounting seat 111, the second conductive sheet 122 is slidably arranged inside the mounting seat 111, two limiting rods 123 are fixed inside the mounting seat 111, the two limiting rods 123 both pass through the second conductive sheet 122, and are slidably connected to the second conductive sheet 122, the two second magnetic blocks 124 are respectively fixed to the upper and lower ends of the second conductive sheet 122, the second magnetic block 124 at the lower end has a magnetic pole opposite to the first magnetic block 112, and the second magnetic block 124 at the upper end has a magnetic pole opposite to the first magnetic block 112;

[0057] The separated oil eventually flows into the oil collection box 101 and accumulates in the oil collection box 101. When there is no oil in the oil collection box 101, the first magnetic block 112 is in the lower limit position under the action of gravity. At this time, the first magnetic block 112 is just opposite to the second magnetic block 124 at the bottom of the second conductive sheet 122. The second magnetic block 124 at the lower end is opposite to the magnetic pole of the first magnetic block 112. Under the action of opposite poles attracting each other, the first magnetic block 112 can magnetically attract the second magnetic block 124 at the lower end, so that the second conductive sheet 122 is located close to the first magnetic block 112. In this case, the first conductive sheet 121 and the second conductive sheet 122 are separated from each other. As the oil accumulates, the float 115 will move upward and drive the first magnetic block 112 to move upward. When the first magnetic block 112 moves to the upper limit position, the first magnetic block 112 is just opposite to the second magnetic block 124 at the top of the second conductive sheet 122. The second magnetic block 124 at the upper end has the same pole as the magnetic pole opposite to the first magnetic block 112. Under the effect of the repulsion of the same poles, the first magnetic block 112 can exert a magnetic repulsive force on the second magnetic block 124 at the upper end, so that the second magnetic block 124 at the upper end drives the second conductive sheet 122 to move until the second conductive sheet 122 contacts the first conductive sheet 121. When the two are in contact, the circulating pump 102 is powered on and operates. When the circulating pump 102 is running, it extracts the oil in the oil collection box 101 and pumps the oil into the two oil storage tanks 41 through the two return pipes 104, respectively, to realize automatic recovery of the oil for the recycling of the oil. When being pumped out by the circulation pump 102, the oil in the oil collection box 101 gradually decreases, and the float 115 also moves downward, driving the first magnetic block 112 to move downward. When the first magnetic block 112 moves to the lower limit position again, the second conductive sheet 122 will move under the action of the first magnetic block 112 and the second magnetic block 124 at the lower end, and separate from the first conductive sheet 121. At this time, the circulation pump 102 is powered off and stops running. Based on the above process, whenever the first magnetic block 112 moves to a position opposite to the second magnetic block 124 at the upper end, the circulation pump 102 can pump the oil collected in the oil collection box 101 into the two oil storage tanks 41. This design realizes automatic recovery of the oil without manual intervention. It should be noted that the circuit connection method between the first conductive sheet 121, the second conductive sheet 122 and the circulation pump 102 is a prior art and will not be elaborated on here.
