[0019] The present invention cooperates with structures such as a water outlet pipe and a water storage pipe. When the drilling is completed and the movable plate and the water outlet pipe move upward synchronously, the water outlet pipe generates pressure on the water between the water outlet pipe and the water storage pipe. Since the water cannot flow back into the water storage pipe, it will squeeze the one-way valve and spray downward from the nozzle to the surface of the circular workpiece, so that the circular workpiece after the drilling can be cooled, thereby avoiding the problem of excessive temperature of the circular workpiece due to friction after the drilling, and the operator being unable to take the material in time and needing to wait for it to cool down naturally, thereby reducing work efficiency.

DETAILED DESCRIPTION

[0027] 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.

[0028] like Figures 1 to 6 As shown, the present invention provides a drilling device for mechanical manufacturing, including a base 1, a top plate 5 is fixedly connected to the top outer wall of the base 1, a movable plate 7 is arranged on the bottom outer wall of the top plate 5 through a cylinder 6, a drill bit 9 is fixedly connected to the bottom outer wall of the movable plate 7, a motor 8 is fixedly connected to the top outer wall of the movable plate 7, a cleaning mechanism 4 is arranged on the outer wall of the top plate 5, a dust collection mechanism 3 is arranged on the outer wall of the base 1, and a fixing mechanism 2 is arranged on the outer wall of the base 1; the fixing mechanism 2 includes a fixing plate 201, and the outer wall of the fixing plate 201 is fixedly connected to A placing plate 202 is provided, and a guide groove 203 is provided on the outer wall of the placing plate 202. The inner wall of the placing plate 202 is rotatably connected to a rotating plate 206. The outer wall of the rotating plate 206 is provided with an inclined groove 207. The inner wall of the inclined groove 207 is slidably connected to a sliding rod 205. The outer wall of the sliding rod 205 is fixedly connected to a clamping block 204. The outer wall of the rotating plate 206 is fixedly connected to a fixed block 208. The inner wall of the fixed block 208 is elastically connected to an insert block 210 via a connecting spring 209. The outer wall of the fixed disk 201 is provided with a slot 211.

[0029] The above scheme is adopted: the movable end of the cylinder 6 is fixedly connected to the top outer wall of the movable plate 7, and the other end is fixed to the bottom outer wall of the top plate 5. When the cylinder 6 is started, its movable end can drive the movable plate 7 to move up and down, so that the drill bit 9 moves synchronously to drill a circular workpiece; the motor 8 is electrically connected to the drill bit 9, and when the motor 8 is started, the drill rod in the drill bit 9 can be rotated to drill a circular workpiece. The circular workpiece can be placed on the fixing mechanism 2 and fixed by the fixing mechanism 2. The fixing mechanism 2 is more convenient and quick when fixing the circular workpiece, and can also be suitable for It can be used for circular workpieces of different sizes; when the drill bit 9 completes drilling, the cylinder 6 drives the movable plate 7 to move upward and reset to make the drill bit 9 away from the circular workpiece. At this time, the cleaning mechanism 4 can spray water on the surface of the circular workpiece to reduce the temperature generated during the drilling process, making it convenient for the operator to take the workpiece; during the drilling process, the waste chips generated can be sucked into the dust box 301 through the dust suction mechanism 3. The outer wall of the dust box 301 is provided with a door panel. The waste chips inside can be cleaned by opening the door panel, thereby avoiding the problem of waste chips splashing and polluting the environment.

[0030] like Figure 3 and Figure 4As shown, the fixed plate 201 is fixedly connected to the top outer wall of the base 1, the sliding rod 205 contacts the inner wall of the guide groove 203, and the fixed block 208 penetrates the outer wall of one side of the placement plate 202; one end of the connecting spring 209 is fixedly connected to the outer wall of the plug block 210, and the other end of the connecting spring 209 is fixedly connected to the inner wall of the fixed block 208; the outer wall of the plug block 210 is slidably connected to the inner wall of the fixed block 208, and the plug block 210 is snap-fitted into the slot 211.

[0031] The above scheme is adopted: the circular workpiece can be placed on the placement plate 202 and fixed on both sides by the clamping blocks 204 on both sides. The sliding rod 205 under the clamping block 204 is always in contact with the inner wall of the guide groove 203 and the inclined groove 207. The rotating plate 206 can be driven to rotate by toggling the fixing block 208. During the rotation, the inner wall of the inclined groove 207 squeezes the sliding rod 205 to make it move. The sliding rod 205 is guided by the guide groove 203 and keeps a horizontal movement along its inner wall, and can move to both sides or the middle at the same time, thereby driving the corresponding clamping block 204 to move to the middle or both sides at the same time to clamp the circular workpiece; when not affected by external forces, the connecting spring 20 Due to its own elastic force, the insert block 210 is kept in a state of being engaged with a group of slots 211 below, so as to limit the fixed block 208 and the rotating plate 206, and fix the positions of the two groups of clamping blocks 204. When it is necessary to move the fixed block 208, the insert block 210 can be pulled upward to compress the connecting spring 209 and disengage the contact with the slot 211. The limit of the fixed block 208 can be released and it can be moved to drive the rotating plate 206 to rotate; since there are multiple groups of slots 211, the rotating plate 206 can be rotated to multiple angles. By engaging the insert block 210 with one group of slots 211, the clamping block 204 can be fixed at different positions, and circular workpieces of different sizes can be clamped and fixed, which is more convenient and has higher adaptability.

[0032] like Figure 5 As shown, the dust collection mechanism 3 includes a dust collection box 301, the outer wall of the dust collection box 301 is provided with a dust collection head 303 through an air pump 302, the top inner wall of the dust collection box 301 is elastically connected to an extrusion plate 305 through a return spring 304, and the top outer wall of the extrusion plate 305 is hinged with a handle 307 through a connecting rod 306; the dust collection box 301 is fixedly connected to the outer wall of the base 1, and the handle 307 is slidably connected to the top inner wall of the dust collection box 301; one end of the return spring 304 is fixedly connected to the outer wall of the extrusion plate 305, and the other end of the return spring 304 is fixedly connected to the inner wall of the dust collection box 301, and the extrusion plate 305 is slidably connected to the inner wall of the dust collection box 301; one end of the connecting rod 306 is hinged to the outer wall of the handle 307, and the other end of the connecting rod 306 is hinged to the outer wall of the extrusion plate 305.

[0033] The above scheme is adopted: the position of the dust suction head 303 corresponds to that of the fixing mechanism 2, and the air pump 302 can be started during the drilling process. The waste chips generated on the circular workpiece will be sucked into the dust suction box 301 by the suction force of the air pump 302 and the dust suction head 303, so that they will not splash and pollute the working environment; the dust suction head 303 is connected to the inner wall of the dust suction box 301 through the air pump 302, and the waste chips are accumulated in the dust suction box 301 after being sucked. When the accumulation reaches a certain extent, the handle 307 can be pulled horizontally to drive one end of the connecting rod 306 to move. Since the squeezing plate 305 is slidably connected to the inner wall of the dust suction box 301, it can only move vertically in the box, so that the connecting rod 306 is flipped, and the other end thereof can drive the squeezing plate 305 to move vertically downward, and the return spring 304 is stretched by force, and the squeezing plate 305 can squeeze the waste chips in the dust suction box 301, so that the waste chips are accumulated more compactly, thereby reducing the space occupied by the waste chips, and more waste chips can be collected.

[0034] After the downward pressure is completed, the handle 307 can be released, and the reset spring 304 will drive the extrusion plate 305 to move upward and reset due to its own elastic force, and the connecting rod 306 will flip reversely, driving the handle 307 to move reversely and reset. At this time, there is still space in the dust box 301 to load more waste chips, which improves the utilization rate of the space in the box, reduces the frequency of the operator cleaning the waste chips in the dust box 301, and reduces work efficiency; when the waste chips in the dust box 301 are completely filled, the operator can open the door panel of the outer wall of the dust box 301 to clean the waste chips inside.

[0035] like Figure 6 As shown, the cleaning mechanism 4 includes a water tank 401, the outer wall of the bottom end of the water tank 401 is fixedly connected with a water storage pipe 402, the inner wall of the water storage pipe 402 is fixedly connected with a one-way valve 403, the outer wall of the water storage pipe 402 is slidably connected with a water outlet pipe 404, the inner wall of the water outlet pipe 404 is fixedly connected with a one-way valve 405, and the outer wall of the water outlet pipe 404 is fixedly connected with a nozzle 406; the water tank 401 is fixedly connected to the outer wall of the top plate 5, the water storage pipe 402 passes through the outer wall of the top plate 5, and the water outlet pipe 404 is fixedly connected to the outer wall of the movable plate 7.

[0036] The above scheme is adopted: through the cleaning mechanism 4, water can be sprayed on the surface of the circular workpiece when the drilling is completed and the movable plate 7 and the drill bit 9 move upward to reset, so as to reduce the temperature generated during the drilling process and make it easier for the operator to take it; the water tank 401 is connected with the water storage pipe 402, the water storage pipe 402 passes through the outer wall of the top plate 5, and the water storage pipe 402 is also connected with the water outlet pipe 404. The one-way valve 403 allows the water in the water storage pipe 402 to only flow into the water outlet pipe 404, but cannot flow back from the water outlet pipe 404 to the water storage pipe 402; when drilling, when the movable plate 7 and the drill bit 9 move downward synchronously, the water outlet pipe 404 moves downward, the volume of the cavity between the water outlet pipe 404 and the water storage pipe 402 increases, and the water in the water tank 401 passes through the water storage pipe 402 and the one-way valve 403. The water flows into the water outlet pipe 404 through the valve 403, and is blocked by the one-way valve 405 and does not flow downward any more, but is stored in the cavity between the water storage pipe 402 and the water outlet pipe 404; when the drilling is completed, the movable plate 7 and the drill bit 9 drive the water outlet pipe 404 to move upward, and the volume of the cavity between the water outlet pipe 404 and the water storage pipe 402 is reduced, and the water outlet pipe 404 squeezes the water. Since the water cannot flow back into the water storage pipe 402, the one-way valve 405 is squeezed, the one-way valve 405 is opened and sprayed from the nozzle 406 onto the circular workpiece, and then the circular workpiece can be sprayed with water to cool it down, so as to avoid the problem that the heat generated by friction during the drilling process is too high, which makes the operator unable to take the material in time and needs to wait for it to cool down naturally, which is a waste of time.

[0037] The working principle and use process of the present invention:

[0038] The operator can first place the circular workpiece on the placing plate 202 of the fixing mechanism 2, pull the insert block 210 upwards, compress the connecting spring 209, so that the insert block 210 is out of contact with the slot 211, and the limit of the fixing block 208 is released. By moving the fixing block 208, the rotating plate 206 is driven to rotate, and the inclined groove 207 on the rotating plate 206 squeezes the sliding rod 205. Under the guidance of the guide groove 203, the sliding rod 205 drives the clamping block 204 to move to the middle or both sides at the same time. When the two sets of clamping blocks 204 are in contact with the surface of the circular workpiece, the fixing block 208 is brought into contact with the fixing block 208. The movable rotating plate 206 is rotated to a suitable angle, and the plug block 210 is released. The connecting spring 209 causes the plug block 210 to pop out downward due to its own elastic force and engage with another set of slots 211, thereby fixing the clamping block 204 in a suitable position to clamp and fix circular workpieces of different sizes. The operation process is relatively convenient and quick, and there is no need to adjust and fix the position of the clamping block 204 by rotating bolts or threaded rods multiple times, which saves time and effort. By setting multiple sets of slots 211, the fixing mechanism 2 can fix circular workpieces of different sizes, and has high adaptability.

[0039] When the circular workpiece is fixed, the motor 8 can be started, and the motor 8 can rotate the drill rod in the drill bit 9, and then the cylinder 6 can be started, and the movable end of the cylinder 6 can drive the movable plate 7 to move downward, so that the drill bit 9 approaches the circular workpiece and drills a hole in it; during the drilling process, the air pump 302 is started, and the dust suction head 303 uses the suction force of the air pump 302 to suck the waste chips generated on the circular workpiece into the dust suction box 301; after the waste chips accumulate to a certain extent in the dust suction box 301, the drilling operation can be stopped first, and the waste chips can be stopped from being sucked in, and the connecting rod 306 can be driven to turn over by pulling the handle 307 horizontally. The handle 307 is rotated to make the squeezing plate 305 move vertically downward, and the return spring 304 is stretched by force, so that the squeezing plate 305 squeezes the waste chips in the dust box 301, so that the waste chips are piled more compactly, reducing the occupied space, so that more waste chips can be collected; after the handle 307 is released, the return spring 304 drives the squeezing plate 305 to move upward and reset, and the dust box 301 can continue to collect waste chips; when the dust box 301 is completely filled with waste chips, the operator can open the door panel to clean the waste chips inside, thereby reducing the frequency of the operator's cleaning of the waste chips in the dust box 301 and alleviating the work intensity.

[0040] When drilling, the movable plate 7 and the drill bit 9 move downward synchronously, which will drive the water outlet pipe 404 to move downward, and the cavity volume between the water outlet pipe 404 and the water storage pipe 402 will increase. The water in the water tank 401 flows into the water outlet pipe 404 through the water storage pipe 402 and the one-way valve 403, and is blocked and stored by the one-way valve 405; after the drilling is completed, the movable plate 7 and the drill bit 9 drive the water outlet pipe 404 to move upward, and the cavity volume between the water outlet pipe 404 and the water storage pipe 402 is reduced. The water outlet pipe 404 squeezes the water. Due to the setting of the one-way valve 403, the water cannot flow back into the water storage pipe 402, but squeezes the one-way valve 405 to open it, and sprays it from the nozzle 406 onto the circular workpiece, spraying water to cool the circular workpiece, making it convenient for the operator to take it, avoiding the excessive heat generated by the friction of drilling, which causes the operator to wait for the workpiece to cool naturally before taking it, thereby wasting time and reducing work efficiency.
