Description

Technical Field

[0001] The utility model relates to the technical field of chip suction equipment, in particular to a vacuum chip suction device for a drilling and tapping machine. Background Art

[0002] A drilling and tapping machine is a machine that can drill and tap on the surface of a workpiece. Its main structural components include machine tools, cutting tools, conveying devices and control systems. The drilling and tapping machine uses CNC technology and automated control methods to achieve an efficient and precise processing process, which can greatly improve production efficiency and processing quality. Drilling and tapping machines are widely used in the processing of aluminum profiles, copper profiles, steel, stainless steel, plastic steel, zinc alloy, aluminum alloy and other materials, and no oil residue will be produced during the processing, which has environmental advantages.

[0003] In the prior art, when drilling and tapping machines drill and tap workpieces, waste chips are generated. If the chips cannot be removed quickly and in time, it will not only affect the subsequent drilling process, but also cause dust accumulation and damage to the equipment. The processing of some workpieces requires a vacuum environment with extremely low air density, and the drilling and tapping machines use water to cool the drill bit. In order to allow water to flow out, the height of the cutting platform is generally inconsistent, and the whole presents an inclined surface. The existing chip suction equipment has a fixed height. When performing the chip suction operation, due to the fixed height, the chip suction effect is good at the higher part of the inclined surface, while the chip suction effect is poor at the lower part, resulting in the inability to efficiently and thoroughly remove the chips and dust at the same time. The missed dust will cause dust in the processing workshop and pollute the air environment. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a vacuum chip suction device for a drilling and tapping machine.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a vacuum chip suction device for a drilling and tapping machine, comprising a cutting table, the back side of the cutting table is detachably connected to a base, the bottom of the base is fixed with a dust box, the top of the base is fixed with a support column, the top of the support column is rotatably connected to a double round head connecting rod, the double round head connecting rod is rotatably connected to a long connecting rod, a load moving plate is fixed to the top of the base, a parallel slide groove is provided on one side of the load moving plate, a moving slider is slidably connected to the inner wall of the parallel slide groove, an oblique vertical groove is provided on the surface of the moving slider, and one side of the moving slider is connected to the long connecting rod. One end of the rod is rotatably connected, and the load moving plate is provided with an inverted L slide groove, and the inner wall of the inverted L slide groove is slidably connected with a square slider, and circular limiting blocks are fixed on both sides of the square slider, and the surface of the circular limiting block is slidably connected with the inner wall of the oblique vertical groove, and an arm piece is fixed on the front of the circular limiting block, and a dust suction piece is fixed on the bottom of one end of the arm piece, and a dust pipe is fixed on the bottom of the arm piece, and one end of the dust pipe is fixed on the top of the dust collecting box. In the prior art, when the drilling and tapping machine drills and taps the workpiece, waste chips are generated. If the chips cannot be removed quickly and in time, it will not only affect the subsequent drilling process, but also cause the equipment to be damaged. The equipment is damaged by dust accumulation, and some workpieces require a vacuum environment when processing, with extremely low air density. In addition, the drilling and tapping machine uses water to cool the drill bit. In order to allow the water to flow out, the height of the cutting platform is generally inconsistent, and the whole presents an inclined surface. The existing chip suction equipment has a fixed height. When performing chip suction operations, due to the fixed height, the chip suction effect is good at the higher part of the inclined surface, while the chip suction equipment at the lower part has a poor effect, resulting in that the debris and dust cannot be efficiently and thoroughly removed at the same time. The dust that is missed will cause dust in the processing workshop and pollute the air environment. In view of such problems, the utility model adopts the method of installing a load motion plate to solve the problem, which realizes When the drilling and tapping machine produces waste chips, the staff starts the double round head connecting rod to rotate clockwise. When the moving slider is pushed to the higher side of the cutting table to the vertical position of the inverted L-chute, due to the limitation of the oblique vertical groove, the square slider drives the dust collector to move upward along the vertical position of the inverted L-chute, and then moves along the parallel position of the inverted L-chute to suck out the waste chips at the higher part of the cutting table. The double round head connecting rod continues to rotate clockwise to make the dust collector return and descend at the vertical position of the inverted L-chute to suck out the waste chips at the lower part of the cutting table, ensuring the vacuum suction effect with low air density and different heights, thereby increasing the service life of the equipment and the precision of drilling and tapping.

[0006] Preferably, a fixing nail is fixed to the side of the cutting table, a fixing circular wing is fixed to the top of the base, a fixing hole is opened on the fixing circular wing, the surface of the fixing nail is slidably connected to the inner wall of the fixing hole, a rotating column is rotatably connected to a circular array on one side of the fixing circular wing, a bite knife is fixed on the surface of the rotating column, a boosting hook is fixed on the surface of the rotating column, a pressing column is rotatably connected to one side of the fixing circular wing, a main rotating part is rotatably connected to one side of the fixing circular wing, and a belt is slidably connected to the pressing column, the main rotating part and the rotating column surface. In the prior art, due to the different shapes and sizes of the workpieces to be processed, the placement position and the corresponding position where chips need to be sucked are also different, If manufacturers install chip suction equipment around the cutting table, the production cost of the equipment will be high, and multiple chip suction equipment will work at the same time and consume their service life, which will greatly increase the cost of later management and maintenance, resulting in increased production costs. To solve this problem, the utility model adopts the method of installing fixed circular wings to solve it. When the staff needs to install chip suction equipment at different positions, the fixing nail is slid into the fixing hole of the fixed circular wing, the main rotating part is started to rotate, and the belt drives the rotating columns to rotate, so that the biting knife converges to the center of the fixing hole, bites the fixing nail, quickly completes the fixation and is easy to disassemble, thereby improving user experience and reducing production costs.

[0007] Preferably, a weight-reducing groove is provided on the surface of the base. In the prior art, since the chip suction device itself needs to be installed with components such as a motor and a turbine to generate negative pressure, its own weight is relatively heavy. After installation, it always tends to turn outward under the influence of gravity, which can easily cause damage to many fixed components. Its impact is more obvious after the dust box collects waste chips, causing the equipment to fall and be damaged, affecting its service life. To solve this problem, the utility model adopts the method of providing a weight-reducing groove to achieve a solution. By providing a weight-reducing groove, the weight of the device itself is reduced, the tendency to turn outward is reduced, and the pressure on the fixed components is reduced. At the same time, the production materials are reduced, the production costs are reduced, and the service life of the equipment is increased.

[0008] Preferably, guide grooves are provided on both sides of the top of the dust collecting box. The drilling and tapping machine generally cools the drill bit with cooling liquid, and the guide grooves guide the outflowing cooling liquid to avoid water short circuit in the device.

[0009] Preferably, the parallel slide groove is a trapezoidal groove, and the moving slider is trapezoidal. The sliding connection between the trapezoidal groove and the trapezoidal block can prevent the moving slider from shaking back and forth, thereby improving the accuracy of the equipment.

[0010] Preferably, an indicator light is fixed to one end of the arm to facilitate staff to observe the operation of the equipment.

[0011] Preferably, the fixed angle between one end of the boost hook and the surface of the rotating column is less than 30 degrees, thereby increasing the friction between the belt and the surface of the rotating column.

[0012] Beneficial Effects

[0013] 1. In the prior art, when drilling and tapping a workpiece, waste chips will be generated. If the chips cannot be removed quickly and in time, it will not only affect the subsequent drilling process, but also cause dust accumulation and damage to the equipment. Some workpieces require a vacuum environment when processing, and the air density is extremely low. In addition, the drilling and tapping machine uses water to cool the drill bit. In order to allow water to flow out, the height of the cutting platform is generally inconsistent, and the whole presents an inclined surface. The existing chip suction equipment has a fixed height. When performing the chip suction operation, due to the fixed height, the chip suction effect is good at the higher part of the inclined surface, while the chip suction effect is poor at the lower part, resulting in the chips and dust cannot be efficiently and thoroughly removed at the same time. The missed dust will cause dust in the processing workshop, polluting the air environment. The utility model solves this problem by installing a load moving plate. When the drilling and tapping machine generates waste chips, the staff starts the double round head connecting rod to rotate clockwise. When the moving slider is pushed to the higher side of the cutting table to the vertical position of the inverted L-shaped slide groove, due to the limitation of the oblique vertical groove, the square slider drives the dust collecting part to move upward along the vertical position of the inverted L-shaped slide groove, and then moves along the parallel position of the inverted L-shaped slide groove to suck out the waste chips at the higher part of the cutting table. The double round head connecting rod continues to rotate clockwise to make the dust collecting part return and descend at the vertical position of the inverted L-shaped slide groove to suck out the waste chips at the lower part of the cutting table, thereby ensuring the vacuum suction effect with low air density and different heights, thereby improving the service life of the equipment and increasing the precision of drilling and tapping.

[0014] 2. In the prior art, since the shapes and sizes of the workpieces to be processed are different, the placement positions and the corresponding positions where chip suction is required are also different. If the manufacturer installs chip suction equipment around the cutting table, the equipment production cost will be high, and multiple chip suction equipment will work at the same time and consume their service life, resulting in a significant increase in the subsequent management and maintenance costs, causing an increase in production costs. To address this problem, the utility model solves it by installing fixed circular wings. When the staff needs to install chip suction equipment at different positions, the fixing nail is slid into the fixing hole of the fixed circular wing, the main rotating part is started to rotate, and the belt drives the rotating columns to rotate, so that the biting knife converges to the center of the fixing hole, bites the fixing nail, quickly completes the fixation and is easy to disassemble, thereby improving user experience and reducing production costs.

[0015] 3. In the prior art, since the chip suction device itself needs to be installed with motors, turbines and other components to generate negative pressure, its own weight is heavy. After installation, it always tends to turn outward under the influence of gravity, which can easily cause damage to many fixed components. The impact is more obvious after the dust box collects waste chips, causing the equipment to fall and be damaged, affecting its service life. To solve this problem, the utility model adopts the method of opening a weight-reducing groove to achieve a solution. By opening a weight-reducing groove, the weight of the device itself is reduced, the tendency to turn outward is reduced, and the pressure on the fixed components is reduced. At the same time, the production materials are reduced, the production costs are reduced, and the effect of increasing the service life of the equipment is achieved.

The movable plate 204 is provided with an inverted L-shaped chute 206, and a square slider 2010 is slidably connected to the inner wall of the inverted L-shaped chute 206. Circular limiting blocks 209 are fixed on both sides of the square slider 2010. The surface of the circular limiting block 209 is slidably connected to the inner wall of the oblique vertical groove 208. An arm 2011 is fixed on the front of the circular limiting block 209. A dust collecting member 2012 is fixed to the bottom of one end of the arm 2011. A dust pipe 2013 is fixed to the bottom of the arm 2011. One end of the dust pipe 2013 is fixed to the top of the dust collecting box 3. When the drilling and tapping machine drills and taps the workpiece, waste chips will be generated. If the chips cannot be removed quickly and in time, it will not only affect the subsequent drilling process, but also It will cause dust accumulation and damage to the equipment. Some workpieces require a vacuum environment when processing, and the air density is extremely low. In addition, the drilling and tapping machine uses water to cool the drill bit. In order to allow the water to flow out, the height of the cutting platform is generally inconsistent, and the whole presents an inclined surface. The existing chip suction equipment has a fixed height. During the chip suction operation, due to the fixed height, the chip suction effect is good at the higher part of the inclined surface, while the chip suction effect is poor at the lower part, resulting in the chips and dust cannot be removed efficiently and thoroughly at the same time. The missed dust will cause dust in the processing workshop and pollute the air environment. The solution is to install a load motion plate 204, so that when the drilling and tapping machine produces waste chips, the staff starts the double round head connecting rod 2 02 rotates clockwise, when the moving slider 207 is pushed to move to the higher side of the cutting table 1 to the vertical position of the inverted L-shaped chute 206, due to the restriction of the oblique vertical chute 208, the square slider 2010 drives the dust collecting part 2012 to move upward along the vertical position of the inverted L-shaped chute 206, and then moves along the parallel position of the inverted L-shaped chute 206 to remove the waste chips at the higher position of the cutting table 1. The double round head connecting rod 202 continues to rotate clockwise, so that the dust collecting part 2012 returns and descends at the vertical position of the inverted L-shaped chute 206 to remove the waste chips at the lower position of the cutting table 1, ensuring the vacuum low air density and the suction effect at different heights, so as to achieve the effect of increasing the service life of the equipment and increasing the precision of drilling and tapping. Both sides of the top of the dust collecting box 3 are provided with guide grooves 301. The drilling and tapping machine generally cools the drill bit with cooling liquid. The guide grooves 301 guide the cooling liquid that flows out to avoid water inflow and short circuit of the device. The parallel slide groove 205 is a trapezoidal groove, and the moving slider 207 is a trapezoid. The sliding connection between the trapezoidal groove and the trapezoidal block can prevent the moving slider 207 from shaking back and forth, thereby improving the accuracy of the equipment.An indicator light 5 is fixed at one end of the arm 2011 to facilitate the staff to observe the operation of the equipment.

[0027] A fixing nail 101 is fixed to the side of the cutting table 1, a fixing circular wing 4 is fixed to the top of the base 2, a fixing hole 401 is opened in the fixing circular wing 4, the surface of the fixing nail 101 is slidably connected to the inner wall of the fixing hole 401, a rotating column 402 is rotatably connected to one side of the fixing circular wing 4 in a circular array, a bite knife 404 is fixed to the surface of the rotating column 402, a booster hook 403 is fixed to the surface of the rotating column 402, a pressing column 405 is rotatably connected to one side of the fixing circular wing 4, a main rotating part 406 is rotatably connected to one side of the fixing circular wing 4, and a belt 407 is slidably connected to the pressing column 405, the main rotating part 406 and the surface of the rotating column 402. Due to the different shapes and sizes of the workpieces to be processed, the placement position and the corresponding position where the chips need to be sucked are also different. Similarly, if the manufacturer installs chip suction equipment around the cutting table 1, it will cause high equipment production costs, and multiple chip suction equipment will work at the same time and consume their service life, resulting in a significant increase in later management and maintenance costs, which will increase production costs. The method of installing a fixed circular wing 4 is used to solve this problem. When the staff needs to install the chip suction equipment at different positions, the fixing nail 101 is slid into the fixing hole 401 of the fixed circular wing 4, the main rotating part 406 is started to rotate, and the belt 407 drives each rotating column 402 to rotate, so that the bite knife 404 converges to the center of the fixing hole 401, bites the fixing nail 101, and quickly completes the fixation and is easy to disassemble, thereby improving user experience and reducing production costs. The fixing angle between one end of the boost hook 403 and the surface of the rotating column 402 is less than 30 degrees, which increases the friction between the belt 407 and the surface of the rotating column 402. A weight-reducing groove 2014 is provided on the surface of the base 2. Since the chip suction device itself needs to be installed with components such as a motor and a turbine to generate negative pressure, its own weight is heavy. After installation, it always tends to turn outward under the influence of gravity, which can easily cause damage to many fixed components. Its impact is more obvious after the dust box 3 collects waste chips, causing the equipment to fall and be damaged, affecting its service life. This problem is solved by providing a weight-reducing groove 2014. By providing a weight-reducing groove 2014, the weight of the device itself is reduced, the tendency to turn outward is reduced, and the pressure on the fixed components is reduced. At the same time, the production materials are reduced, the production costs are reduced, and the effect of increasing the service life of the equipment is achieved.

[0028] The working principle of the utility model is as follows: when the staff needs to install the chip suction device at different positions, the fixing nail 101 is slid into the fixing hole 401 of the fixing round wing 4, the main rotating part 406 is started to rotate, and the belt 407 drives each rotating column 402 to rotate, so that the bite knife 404 converges to the center of the fixing hole 401, bites the fixing nail 101, and the fixing is completed quickly and is easy to disassemble. When the drilling and tapping machine produces waste chips, the staff starts the double round head connecting rod 202 to rotate clockwise, and when the moving slider 207 is pushed toward the cutting table 1 When the higher side moves to the vertical position of the inverted L-shaped slide groove 206, due to the limitation of the oblique vertical groove 208, the square slider 2010 drives the dust collecting part 2012 to move upward along the vertical position of the inverted L-shaped slide groove 206, and then moves along the parallel position of the inverted L-shaped slide groove 206 to suck out the waste chips at the higher position of the cutting table 1. The double round-head connecting rod 202 continues to rotate clockwise to make the dust collecting part 2012 return and descend at the vertical position of the inverted L-shaped slide groove 206 to suck out the waste chips at the lower position of the cutting table 1, thereby ensuring the vacuum low air density and the suction effect at different heights.
