Description

Technical Field

[0001] The invention relates to the technical field of drilling processing, in particular to a waste collection device of a metal part drilling machine. Background Art

[0002] A hole turning machine, also known as a drilling machine, is a device for opening holes on a workpiece. When an existing metal part is subjected to hole opening processing by a drilling machine, the metal part is placed on a positioning seat for positioning, and the rotating drill bit is pressed down to perform hole opening processing on the surface of the metal part. Waste is generated in the process, and the waste is scattered on the processing table, polluting the environment. At the same time, the waste is scattered on the positioning seat, which will affect the positioning effect of the metal part. Therefore, the waste generated by the drilling process needs to be cleaned.

[0003] The waste cleaning device equipped with the existing drilling machine mainly utilizes a high-power negative pressure suction device to suck the generated waste into the waste box. When the waste generated by drilling comes into contact with the drill bit, it will be thrown to the periphery by the high-speed rotating drill bit and will be separated from the negative pressure suction. There will still be waste splashing, and the cleaning effect is not good. Summary of the invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0016] 1. The present invention utilizes an annular enclosure to intercept waste debris thrown off by the drill bit, thereby preventing the waste debris from randomly splashing on the workbench. The driving mechanism drives the annular enclosure to rotate, and the push plate scrapes the waste debris accumulated in the annular temporary storage chamber to the discharge port for discharge. The blowing device rotates to blow the waste on the surface of the processed metal part and the surface of the placement table into the annular temporary storage chamber, which has a good effect on collecting the waste. In addition, the blowing device rotates to blow from multiple directions, avoiding the existence of dead corners and leakage, thereby ensuring the blowing effect of the waste.

[0017] 2. In the present invention, when the blocking cover moves down to block the upper end of the annular enclosure, the lower pressure rod presses the pressure-bearing rod downward, driving the push rod to slide downward, making room in the clearance hole to provide clearance space for the drill bit. At this time, the spring is compressed and stores force. When the blocking cover moves up to drive the lower pressure rod to separate from the pressure-bearing rod, the elastic reset of the spring pushes the connecting plate upward, thereby driving the push rod and the pressure-bearing rod to slide upward and reset, until the upper end surface of the push rod is not lower than the upper surface of the placement table, the waste debris that falls into the clearance hole can be pushed upward to the outside so as to be blown away, thereby avoiding excessive accumulation of debris in the clearance hole and affecting the clearance effect of the drill bit.

[0018] 3. The present invention drives the auger rod to rotate in the conveying cylinder through the operation of the second driving motor. The rotating auger rod can spirally convey the waste debris that falls into the conveying cylinder downward, and finally discharge it into the storage tank for collection. As the auger rod spirals downward, the waste debris in the storage tank can be compacted to reduce the gaps between the waste debris, so that the storage tank can hold more waste debris, and there is no need to frequently replace the storage tank, thereby reducing the labor intensity of the staff.

[0019] 4. The present invention drives the sphere to rotate in the spherical cavity by driving the motor, and then drives the jet head to rotate synchronously, so as to adjust the jet angle, so as to adapt to the jet removal at different heights of the upper surface of the metal part and the inner surface of the placement table. In addition, when the blowing device is not working, the sphere is driven to rotate by the driving motor until the cavity and the connecting hole are misaligned, and the cavity port is blocked by the inner wall of the spherical cavity, so as to achieve an interception effect and prevent dust and debris from entering the second tube body and causing blockage.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1 - Fig.11 The present invention provides a waste collection device for a metal part drilling machine, comprising a workbench 1, a stand 11 fixed on the top of the workbench 1, and a mounting column 12 fixed under the cantilever of the stand 11 and having a drill bit at the bottom end. A placement table 2 is fixed above the workbench 1. When drilling a metal part, the metal part is placed on the placement table 2, and the mounting column 12 and the drill bit are driven downward by a driving device arranged on the cantilever of the stand 11, and the rotating drill bit can perform drilling processing on the metal part.

[0034] An annular enclosure 3 arranged around the placement platform 2 is rotatably installed on the upper surface of the workbench 1. The top end surface height of the annular enclosure 3 is much higher than the upper surface of the placement platform 2. During drilling, the annular enclosure 3 can be used to intercept the waste debris thrown away by the drill bit to prevent the waste debris from splashing on the workbench 1 at will. An annular guide 31 is arranged around the placement platform 2 above the workbench 1. The side wall of the annular guide 31 is inclined. The upper end of the annular guide 31 is fixed to the outer peripheral wall of the placement platform 2 and is fixed to the placement platform 2. The top of the placing table 2 is flush, the lower end of the annular guide 31 is fixed to the upper surface of the working table 1, and an annular temporary storage cavity 32 is formed between the inner edge wall of the annular enclosure 3 and the outer wall of the annular guide 31. The annular guide 31 forms a slope, and the waste debris falling on the annular guide 31 can automatically slide along the inclined surface of the annular guide 31 to the bottom of the annular temporary storage cavity 32. In addition, the waste debris blocked by the annular enclosure 3 will also fall downward into the bottom of the annular temporary storage cavity 32 under the action of gravity.

[0035] The workbench 1 is provided with a driving mechanism 4 for driving the annular enclosure 3 to rotate, and the workbench 1 is provided with a discharge port 101 communicated with the annular guide member 31. A push plate 33 and a blowing device 34 for blowing air toward the top of the placement table 2 are fixed on the inner edge wall of the annular enclosure 3. The bottom end of the annular enclosure 3 is slidably fitted with the upper surface of the workbench 1, and the side end is slidably fitted with the outer peripheral wall of the annular guide member 31. The annular enclosure 3 is driven to rotate by the driving mechanism 4. The rotating annular enclosure 3 can drive the push plate 33 and the blowing device 34 to rotate around the placement table 2. The push plate 33 scrapes the waste debris accumulated in the annular temporary storage chamber 32 to the discharge port 101, and the waste debris is discharged from the discharge port 101. 01 The waste is discharged downward to avoid excessive accumulation of waste debris in the annular temporary storage chamber 32. In addition, when the blowing device 34 rotates, the blowing device 34 can be aimed at the top of the placement table 2 for blowing. On the one hand, the waste on the surface of the processed metal part can be blown into the annular temporary storage chamber 32. On the other hand, after the metal part is removed from the placement table 2, the waste debris falling on the placement table 2 can be blown into the annular temporary storage chamber 32. In addition, the blowing device 34 rotates around the placement table 2 and can blow from different directions to ensure that the blowing range is sufficient to cover the placement table 2 and the upper end of the metal workpiece, thereby improving the blowing effect on the waste debris and avoiding the effect of leaking.

[0036] See also Figure 1 , Figure 2 and Figure 8The mounting column 12 is provided with a blocking cover 5 which can slide up and down, and the position of the blocking cover 5 corresponds to the position of the annular enclosure 3. During the drilling process, the blocking cover 5 moves down synchronously with the mounting column 12 until it is pressed on the annular enclosure 3, which can block the upper end of the annular enclosure 3 to prevent the dust and smoke generated by the drilling process from floating around and polluting the air quality at the processing site. A dust suction pipe 54 is installed through the blocking cover 5, and the end of the dust suction pipe 54 is connected to an industrial vacuum cleaner. Negative pressure is generated by the operation of the industrial vacuum cleaner, and the dust and smoke in the annular enclosure 3 can be negatively pressured and sucked into the industrial vacuum cleaner to achieve dust reduction effect. An interception net 541 is installed at one end of the dust suction pipe 54 away from the industrial vacuum cleaner, and waste debris can be recycled. The interception net 541 can be used to intercept small-volume waste debris to avoid being sucked into the industrial vacuum cleaner and causing waste. The dust suction pipe 54 adopts a soft pipe to adapt to the height change of the blocking cover 5.

[0037] In addition, when drilling, as the depth of the hole increases, the mounting column 12 and the drill bit also descend, and the blocking cover 5 is slidably mounted on the mounting column 12, and the blocking cover 5 and the mounting column 12 have the ability to slide relative to each other. During the descent of the mounting column 12 and the drill bit, the blocking cover 5 slides upward relative to the mounting column 12, which helps the blocking cover 5 to maintain the sealing effect of the annular enclosure 3, so as to ensure that the blocking cover 5 can adapt to the lifting and lowering of the mounting column 12 and the drill bit.

[0038] See also Figure 2 , Figure 6 , Figure 7 and Figure 8 Three first positioning rods 21 are evenly distributed above the placement table 2, and pressure rods 22 are vertically arranged on the placement table 2. A positioning area for positioning and placing the metal workpiece is formed between the pressure rod 22 and the three first positioning rods 21. Positioning and placing the metal workpiece in the positioning area above the placement table 2 can prevent the metal workpiece from arbitrarily shifting during drilling and affecting the drilling accuracy. The first positioning rods 21 and pressure rods 22 protruding upward on the upper surface of the placement table 2 can easily block the waste debris from being blown normally, and there is a dead corner for blowing. The driving mechanism 4 drives the annular enclosure 3 and the blowing device 34 to rotate, and blows air from different directions above the placement table 2, which can avoid the occurrence of dead corners for blowing and improve the effect of blowing away the waste debris above the placement table 2.

[0039] When drilling a through hole on a metal part, it is necessary to ensure that the drill bit passes through the metal part. When the drill bit passes through the metal part, it will contact the placement table 2. Therefore, it is necessary to set a clearance cavity at a position corresponding to the drilling hole on the placement table 2 to ensure that the drill bit can enter the clearance cavity when passing through the metal part to avoid direct contact with the placement table 2. The clearance cavity is sunken and once waste debris falls into it, it is difficult to discharge it. Excessive accumulation of waste debris in the clearance cavity affects the entry of the drill bit. In order to solve this problem, the present invention makes the following improvements:

[0040] An inner cavity 201 is provided in the placing table 2, and the pressure-bearing rod 22 slides through and extends into the inner cavity 201. A clearance hole 202 extending vertically downward and communicating with the inner cavity 201 is provided on the upper surface of the placing table 2. A push rod 23 is installed in the clearance hole 202. The outer wall of the push rod 23 slides tightly and fits with the inner wall of the clearance hole 202, and the bottom end of the push rod 23 extends into the inner cavity 201. A connecting plate 24 is fixed between the bottom end of the push rod 23 and the bottom end of the pressure-bearing rod 22. A vertically extending spring 25 is provided in the inner cavity 201. The top end of the spring 25 is fixed to the lower surface of the connecting plate 24, and the bottom end is fixed to the inner bottom wall of the inner cavity 201. A downward pressing rod 51 extending vertically downward is fixed on the blocking cover 5. The downward pressing rod 51 corresponds to the position of the pressure-bearing rod 22, and they are pressed and matched with each other. When the blocking cover 5 moves down, the annular enclosure is When the upper end is blocked, the lower pressure rod 51 contacts the pressure rod 22 and presses the pressure rod 22 downward. Under the connection of the connecting plate 24, the push rod 23 is driven to slide downward to make room in the clearance hole 202 to provide clearance space for the drill bit. At this time, the spring 25 is compressed and stored. When the blocking cover 5 moves upward to drive the lower pressure rod 51 to separate from the pressure rod 22, the elastic reset of the spring 25 pushes the connecting plate 24 upward, thereby driving the push rod 23 and the pressure rod 22 to slide upward and reset until the upper end surface of the push rod 23 is not lower than the upper surface of the placing table 2. During the upward movement of the push rod 23, the waste debris that falls into the clearance hole 202 can be pushed upward to the outside so as to be blown away, thereby avoiding excessive accumulation of debris in the clearance hole 202 and affecting the clearance effect of the drill bit.

[0041] In addition, two brackets 52 are fixed to the side of the mounting column 12, and a guide rod 53 is vertically fixed between the two brackets 52. A sliding hole 501 which passes through the blocking cover 5 is provided, and the guide rod 53 is slidably installed in the sliding hole 501. The sliding cooperation between the guide rod 53 and the sliding hole 501 plays a guiding and limiting role for the blocking cover 5, so that the lower pressure rod 51 and the pressure-bearing rod 22 are in an aligned positioning state, thereby preventing the blocking cover 5 and the mounting column 12 from rotating relative to each other and causing the lower pressure rod 51 and the pressure-bearing rod 22 to be misaligned.

[0042] The waste debris discharged from the discharge port 101 can be collected by the collection box arranged under the workbench 1 for easy recycling. However, some of the waste generated by the drilling process is spirally curved. After falling into the collection box, the waste debris is in a fluffy state, occupying a large amount of space in the collection box, resulting in the need to frequently replace the collection box, which undoubtedly increases the labor intensity of the staff. In view of this problem, the present invention makes the following improvements:

[0043] See also Figure 2 , Figure 4 and Figure 5A conveying path 102 and an extrusion conveying mechanism 6 are provided under the workbench 1. A storage tank 7 is provided at the bottom of the extrusion conveying mechanism 6. The conveying path 102 is used to convey the waste discharged from the discharge port 101 to the extrusion conveying mechanism 6. The extrusion conveying mechanism 6 is used to spirally compress and convey the waste to the storage tank 7.

[0044] The extrusion conveying mechanism 6 includes a fixed frame 61 fixed to the bottom of the workbench 1, a conveying cylinder 62 fixed to the fixed frame 61 and extending vertically, an auger rod 63 rotatably installed in the conveying cylinder 62, and a second drive motor 64 fixed to the top of the conveying cylinder 62. The conveying path 102 is arranged obliquely, the upper end of the conveying path 102 is connected to the bottom end of the discharge port 101, and the lower end of the conveying path 102 is connected to the feed port on the conveying cylinder 62. The output shaft of the second drive motor 64 extends through the conveying cylinder 62 and is fixedly connected to the top of the auger rod 63. The lower end of the conveying cylinder 62 is open and communicates with the conveying cylinder 62. From the discharge port 101 The discharged waste debris falls on the conveying path 102, and is transported to the conveying cylinder 62 through the conveying path 102. The second drive motor 64 drives the auger rod 63 to rotate in the conveying cylinder 62. The rotating auger rod 63 can spirally transport the waste debris that falls into the conveying cylinder 62 downward, and finally discharge it into the storage tank 7 for collection. As the auger rod 63 spirally transports downward, it can compact the waste debris in the storage tank 7 to reduce the gaps between the waste debris, so that the storage tank 7 can hold more waste debris, and there is no need to frequently replace the storage tank 7, thereby reducing the labor intensity of the staff.

[0045] In addition, the storage tank 7 is detachably mounted on the lower end of the conveying cylinder 62 through threads, so that the storage tank 7 has a detachable effect. By arranging multiple storage tanks 7, it is convenient to disassemble and replace them when fully loaded.

[0046] See also Figure 3 , Figure 5 , Fig. 9 , Fig.10 and Fig.11The blowing device 34 includes a mounting frame 341, a mounting seat 342, a sphere 343, a jet head 344, an air guide pipe 345 and a driving motor 346. The mounting frame 341 is fixed to the inner edge wall of the annular enclosure 3, and the mounting seat 342 is mounted on the end of the mounting frame 341. The mounting seat 342 is provided with a spherical cavity 3421 and a connecting hole 3422. The spherical cavity 3421 is connected to the outside, and the connecting hole 3422 is connected to the spherical cavity 3421. The sphere 343 is matched and installed in the spherical cavity 3421 and has the ability to roll. The sphere 343 is partially exposed to the outside of the mounting seat 342. The sphere 343 is provided with a through cavity 34 31, the inner diameter of the cavity 3431 is smaller than the inner diameter of the connecting hole 3422, the nozzle 344 is fixed on the outer wall of the sphere 343 and communicates with the cavity 3431, the air guide pipe 345 is installed through the annular enclosure 3, and one end of the air guide pipe 345 is connected to the side end of the mounting seat 342 and communicates with the connecting hole 3422, and the other end is connected to the high-pressure air pump. When the high-pressure air pump works, the gas is pumped into the air guide pipe 345, and the high-pressure gas is introduced into the connecting hole 3422 through the air guide pipe 345, and flows to the nozzle 344 through the cavity 3431, and finally ejected, so as to realize the air jet removal of the metal part surface and the upper surface of the placement table 2.

[0047] Since the height of the upper surface of the metal piece placed on the placement table 2 is different from the height of the upper surface of the placement table 2, it is necessary to adjust the jet angle to adapt to the jet impurity removal of the upper surface of the metal piece and the upper surface of the placement table 2. In the present invention, a driving motor 346 is fixed on one side of the mounting seat 342, and the output shaft of the driving motor 346 extends through the spherical cavity 3421 and is fixedly connected to the outer surface of the sphere 343. The driving motor 346 drives the sphere 343 to rotate in the spherical cavity 3421, and then drives the jet head 344 to rotate synchronously to achieve the adjustment of the jet angle. The aperture of the cavity 3431 is smaller than the aperture of the connecting hole 3422, so that when the angle of the sphere 343 and the jet head 344 is adjusted within a certain range, it can also ensure that the gas is normally transported from the connecting hole 3422 to the cavity 3431.

[0048] The air guide tube 345 is divided into two parts, a first tube body 3451 and a second tube body 3452. The first tube body 3451 is a metal tube, and the second tube body 3452 is a spiral air tube. The first tube body 3451 and the second tube body 3452 are interconnected. The other end of the second tube body 3452 is connected to the high-pressure air pump, and the other end of the first tube body 3451 is connected to the connecting hole 3422. A spiral air tube is used as the second tube body 3452. When the annular enclosure 3 rotates, the second tube body 3452 can be adaptively deformed. The annular enclosure 3 needs to automatically reset after one rotation to prevent the second tube body 3452 from being excessively wound around the annular enclosure 3.

[0049] In addition, when the blowing device 34 is not working, some dust and small particles will flow into the second tube 3452 through the nozzle 344, the cavity 3431 and the connecting hole 3422 in sequence. The spirally curved structure layout of the second tube 3452 is prone to cause dust and debris to accumulate somewhere, and excessive accumulation will cause the first tube 3451 and the second tube 3452 to be blocked, affecting the normal gas supply. Furthermore, when the blowing device 34 is not working, the ball 343 is driven to rotate by the driving motor 346 until the cavity 3431 and the connecting hole 3422 are misaligned, and the inner wall of the spherical cavity 3421 is used to block the port of the cavity 3431, thereby intercepting the dust and debris from entering the second tube 3452 and causing blockage. Even if the dust and debris enter, they can only reach the nozzle 344 and the cavity 3431. When it works next time, the high-pressure gas generated can flush out the dust and debris, and will not cause blockage of the cavity 3431 and the nozzle 344.

[0050] See also Figure 1 - Figure 5 The driving mechanism 4 includes a first driving motor 41, a main gear 42 and a gear ring 43. The first driving motor 41 is fixed to the bottom of the workbench 1, and the gear ring 43 is fixedly sleeved on the outer wall of the annular enclosure 3. The output shaft of the first driving motor 41 extends to the top of the workbench 1 and is equipped with a main gear 42. The main gear 42 is meshed with the gear ring 43.
