Description

Technical Field

[0001] The present invention relates to the technical field of fixtures, and in particular to a quickly detachable CNC machine tool fixture. Background Art

[0002] As the machining industry moves toward high precision, high efficiency, and high automation, CNC machine tools, with their exceptional machining performance, have become core equipment for industrial upgrading and refined manufacturing. Their highly automated operating processes precisely execute preset machining instructions, ensuring that components meet stringent standards for dimensional and shape accuracy. They are widely used in aerospace, automotive, electronic equipment, and other fields requiring extremely high component precision.

[0003] However, existing fixtures usually use more cumbersome connection methods such as bolt tightening. When the fixture needs to be replaced to adapt to different processing requirements, the operator has to use various tools and spend a lot of time and energy to tighten the bolts to complete the disassembly and replacement of the fixture. This not only greatly increases the labor intensity of the operator, but also seriously affects the continuity of processing, resulting in low production efficiency.

[0004] In view of this, the existing problems are studied and improved, and a quick-detachable CNC machine tool fixture is provided, aiming to solve the problem and improve the practical value through this technology. Summary of the Invention

The annular tube can be cleaned by pushing the pull plate to ensure the unobstructed operation of the dust collection mechanism. When dusting, the pressure difference is used to stabilize the fixture and improve processing accuracy.

[0008] Preferably, a spring A is sleeved on the outer wall of the insertion rod, one end of the spring A is fixedly connected to one side of the push plate, and the other end of the spring A is fixedly connected to the inner wall of the installation groove.

[0009] Preferably: the dust suction mechanism includes a protective cover welded to the outside of the bottom end of the drill bit, a collection box is installed inside the machine tool body, a dust collector is installed on the top of the collection box, an annular tube is fixedly installed on the top of the protective cover, the bottom end of the annular tube is connected to a dust suction head, and the dust collector and the annular tube are connected through a dust suction tube.

[0010] Preferably, the number of the dust collector heads is arranged in multiple groups, and the multiple groups of dust collector heads are distributed in a circular array along the outer wall of the annular tube.

[0011] Preferably: the knocking mechanism includes a stacked air bag installed inside the mounting groove, a mounting plate is welded to one side of the drill bit, the stacked air bag and the mounting plate are connected by an air pipe, a sleeve is fixedly installed on the side wall of the mounting plate, a piston rod slides inside the sleeve, a spring B is sleeved on the outer wall of the piston rod, one end of the piston rod passing through the inside of the sleeve is fixedly connected to the rack B, a fixing rod is welded to the inner wall of the mounting plate, an eccentric wheel is rotated at the top of the fixing rod through a bearing, a slot plate is rotated on the top of the eccentric wheel, one end of the slot plate is fixedly connected to the knocking rod, and a limited seat is welded on one side of the mounting plate.

[0012] Preferably, one side of the knocking rod is spherical, and the spherical shape is made of elastic material.

[0013] Preferably: the clamping mechanism includes a shell welded to one side of the clamp, a piston plate slides inside the shell, a pressure rod is fixedly connected to the top of the piston plate, one end of the pressure rod passing through the outside of the shell is fixedly connected to the pressure plate, the outer wall of the pressure rod is provided with a spring C, and the dust collector head is connected to the shell through a connecting pipe.

[0014] Preferably, a gasket is provided at the bottom of the pressing plate, and the gasket is made of rubber material.

[0015] Preferably, two groups of symmetrically arranged sliding grooves are provided on the surface of the placement table, and the screw rod rotates inside the sliding grooves.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the gear is in the upright position, the guide rod is rotated with the gear, and the guide rod is pressed against the push plate, so that the rod is inserted into the slot on one side of the fixture to fix the fixture. When the gear is in the upright position, the guide rod is pressed against the push plate, so that the rod is inserted into the slot on one side of the fixture to fix the fixture. When the gear is in the upright position, the guide rod is pressed against the push plate, so that the rod is inserted into the slot on the other side of the fixture to fix the fixture. When the gear is in the upright position, the guide rod is pressed against the push plate, so that the rod is inserted into the slot on the other side of the fixture to fix the fixture. When the gear is in the upright position, the guide rod is pressed against the push plate, so that the rod is inserted into the slot on the

[0018] 2. The present invention enables the operator to push the pull plate downward, and the downward movement of the pull plate will drive the vertical rod to slide downward in the installation groove, and the rack A on the side wall of the vertical rod will move downward synchronously with the vertical rod. When the rack A moves downward, it will drive the half gear to rotate around its rotating shaft, and the guide rod will gradually approach the push plate and apply an extrusion force to the push plate. When the push plate is squeezed by the guide rod, it will move toward the stacked airbag and squeeze the stacked airbag. When the stacked airbag is squeezed, the gas inside it is transported to the inside of the sleeve fixed on the side wall of the mounting plate through the gas pipe. As the gas continues to enter the sleeve, the gas pressure inside the sleeve is constantly increasing. The pressure of the gas in the casing increases continuously. When the gas pressure in the casing increases, the piston rod will be pushed to overcome the elastic force of the spring B and slide in the casing. The movement of the piston rod will drive the rack B to move synchronously, and the rack B will drive the eccentric wheel to rotate. When the eccentric wheel rotates, it will drive the groove plate to move. The movement of the groove plate will drive the knocking rod to knock on the outer wall of the annular tube. The knocking of the annular tube by the knocking rod will cause the annular tube to vibrate. This vibration can clean up the impurities remaining on the inner wall of the annular tube, avoid the accumulation and blockage of waste in the annular tube, ensure the smooth flow of the dust collection mechanism, enable the waste to be collected efficiently, and ensure the stable operation of the dust collection function.

[0019] 3. When the dust suction mechanism of the present invention is working, the vacuum cleaner in the dust suction mechanism is turned on, and a negative pressure environment is formed in the annular tube at the top of the protective cover and the dust suction head connected thereto. Since the dust suction head is connected to the shell through a connecting tube, the negative pressure generated at the dust suction head will be transmitted to the shell. Under the action of the negative pressure, the air in the shell is extracted and the air pressure is reduced. At this time, the piston plate slides downward in the shell under the action of the pressure difference formed by the external atmospheric pressure and the negative pressure in the shell. The sliding of the piston plate drives the pressure rod connected to it to move downward synchronously, and then the pressure plate moves in the direction of approaching the pull plate. As the pressure plate approaches, the pressure plate is finally pressed tightly on the top of the pull plate, preventing the clamp from loosening due to the vibration generated by the processing, ensuring the firm clamping of the workpiece during the processing, and effectively improving the processing accuracy.

[0020] 4. The present invention covers the processing part with a protective cover, thereby blocking the waste, preventing the waste from splashing, and facilitating the absorption of the waste. At the same time, the vacuum cleaner is controlled to start, so that the vacuum cleaner absorbs the debris and other waste generated during processing through the vacuum head, so that the waste enters the interior of the annular tube and then enters the collection box through the vacuum tube for collection, thereby maintaining the cleanliness of the working environment, reducing the possibility of impurities splashing to the fixture installation part, avoiding the difficulty of fixture replacement caused by impurities, and allowing the fixture to be quickly put into normal work after replacement, thereby improving the processing quality.

[0031] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See Figures 1 to 8 As shown, the present invention provides a quickly detachable CNC machine tool fixture, comprising a machine tool body 1, a workbench 2 welded to the top of the machine tool body 1, a placement table 3 detachably mounted on the top of the workbench 2 by bolts, a motor 4 mounted on one side of the placement table 3, a screw rod 5 fixedly mounted on the output end of the motor 4 through a coupling, a splint 6 threadedly connected to the outer wall of the screw rod 5, a fixture 7 detachably connected to one side of the splint 6, a mounting frame 8 slidingly provided on the surface of the workbench 2, a drill bit 9 mounted on the bottom end of the mounting frame 8, a disassembly mechanism 10 for quickly detaching the fixture 7 is provided inside the splint 6, a dust suction mechanism 11 for cleaning impurities on the surface of the placement table 3 is provided on the outside of the drill bit 9, a knocking mechanism 12 for cleaning residual impurities inside the dust suction mechanism 11 is provided between the disassembly mechanism 10 and the dust suction mechanism 11, and a clamping mechanism 13 for preventing the fixture 7 from loosening is provided on one side of the disassembly mechanism 10.

[0033] See Figures 1 to 3 As shown, the disassembly mechanism 10 includes a mounting groove 1001 provided inside the splint 6, a vertical rod 1002 sliding inside the mounting groove 1001, a rack A1003 fixedly connected to the side wall of the vertical rod 1002, a half gear 1004 rotating through a rotating shaft inside the mounting groove 1001, a guide rod 1005 fixedly connected to one side of the half gear 1004, a push plate 1006 sliding inside the mounting groove 1001, an insertion rod 1007 fixedly connected to one side of the push plate 1006, a slot 1008 for plugging with the insertion rod 1007 is provided on one side of the clamp 7, and a pull plate 1009 is fixedly connected to the top of the vertical rod 1002.

[0034] See Figure 3 As shown, a spring A1010 is sleeved on the outer wall of the insertion rod 1007 , one end of the spring A1010 is fixedly connected to one side of the push plate 1006 , and the other end of the spring A1010 is fixedly connected to the inner wall of the mounting groove 1001 .

[0035] It should be noted that when the clamp 7 needs to be disassembled, the operator manually grabs the pull plate 1009 and pulls it upward. The upward movement of the pull plate 1009 will directly drive the vertical rod 1002 to slide upward in the installation groove 1001. When the vertical rod 1002 moves upward, the rack A1003 will move upward synchronously. The half gear 1004 is installed in the installation groove 1001 through the rotating shaft and is engaged with the rack A1003. When the rack A1003 moves upward, it will drive the half gear 1004 to rotate around its rotating shaft. When the half gear 1004 rotates, the guide rod 1005 will rotate with the half gear 1004. When the clamp 7 is installed normally, the guide rod 1005 will exert an extrusion effect on the push plate 1006 to insert the insertion rod 1007 into the clamp. The slot 1008 on one side of 7 realizes the fixation of the clamp 7, and when the half gear 1004 rotates, the guide rod 1005 will gradually release the squeezing of the push plate 1006. After the guide rod 1005 releases the squeezing of the push plate 1006, the spring A1010 will release its elastic potential energy, pushing the push plate 1006 to slide in the installation groove 1001, and the sliding of the push plate 1006 will drive the insertion rod 1007 to move together, and finally the insertion rod 1007 will be disengaged from the slot 1008. At this time, the connection between the clamp 7 and the clamp plate 6 is released, and the operator can quickly disassemble the clamp 7 for replacement, thereby achieving the goal of not using complex tools and cumbersome operating steps, greatly reducing the labor intensity of the operator and improving the convenience of operation.

[0036] See Figures 1 to 6 As shown, the dust collection mechanism 11 includes a protective cover 1101 welded to the outside of the bottom end of the drill bit 9, a collection box 1102 is installed inside the machine tool body 1, a dust collector 1103 is installed on the top of the collection box 1102, an annular tube 1104 is fixedly installed on the top of the protective cover 1101, the bottom end of the annular tube 1104 is connected to the dust collection head 1105, and the dust collector 1103 and the annular tube 1104 are connected through the dust collection tube 1106.

[0037] See Figure 6 As shown, there are multiple groups of dust collector heads 1105 , and the multiple groups of dust collector heads 1105 are distributed in a circular array along the outer wall of the annular tube 1104 .

[0038] It should be noted that when the drill bit 9 is used to drill the workpiece, the protective cover 1101 covers the processing part, thereby blocking the waste material, preventing the waste material from splashing, and facilitating the absorption of the waste material. At the same time, the vacuum cleaner 1103 is controlled to start, so that the vacuum cleaner 1103 absorbs the debris and other waste materials generated during the processing through the dust collector head 1105, so that the waste material enters the interior of the annular tube 1104, and then enters the collection box 1102 through the dust collection tube 1106 for collection, thereby keeping the working environment clean, reducing the possibility of impurities splashing to the installation part of the fixture 7, avoiding the difficulty of replacing the fixture 7 due to impurities, and allowing the fixture 7 to be quickly put into normal operation after replacement, thereby improving the processing quality.

[0039] See Figures 5 to 7 As shown, the knocking mechanism 12 includes a stacked air bag 1201 installed inside the mounting groove 1001, a mounting plate 1202 is welded to one side of the drill bit 9, the stacked air bag 1201 and the mounting plate 1202 are connected by an air pipe 1203, a sleeve 1204 is fixedly installed on the side wall of the mounting plate 1202, a piston rod 1205 is slid inside the sleeve 1204, the outer wall of the piston rod 1205 is sleeved with a spring B1206, and one end of the piston rod 1205 passing through the inside of the sleeve 1204 is fixedly connected to the rack B1207, a fixing rod 1208 is welded to the inner wall of the mounting plate 1202, an eccentric wheel 1209 is rotated at the top of the fixing rod 1208 through a bearing, a slot plate 1210 is rotated on the top of the eccentric wheel 1209, one end of the slot plate 1210 is fixedly connected to the knocking rod 1211, and a limited seat 1212 is welded on one side of the mounting plate 1202.

[0040] See Figure 6 As shown, one side of the knock rod 1211 is spherical, and the spherical shape is made of elastic material.

[0041] It should be noted that when the fixture 7 is installed, the operator pushes the pull plate 1009 downward, and the downward movement of the pull plate 1009 drives the vertical rod 1002 to slide downward in the installation groove 1001. The rack A1003 on the side wall of the vertical rod 1002 moves downward synchronously with the vertical rod 1002. When the rack A1003 moves downward, it drives the half gear 1004 to rotate around its axis. During the rotation of the half gear 1004, the guide rod 1005 gradually approaches the push plate 1006 and pushes the push plate 1006. Applying an extrusion force, when the push plate 1006 is squeezed by the guide rod 1005, it will move toward the stacked airbag 1201 and squeeze the stacked airbag 1201. When the stacked airbag 1201 is squeezed, the gas inside it is transported to the inside of the sleeve 1204 fixed to the side wall of the mounting plate 1202 through the gas pipe 1203. As the gas continues to enter the sleeve 1204, the gas pressure inside the sleeve 1204 continues to increase. When the gas pressure inside the sleeve 1204 increases, it pushes the piston rod 1201. 05 overcomes the elastic force of spring B1206 and slides in sleeve 1204. The movement of piston rod 1205 drives rack B1207 to move synchronously. Since rack B1207 and eccentric wheel 1209 are meshed with each other, when rack B1207 moves, eccentric wheel 1209 is driven to rotate around the bearing at the top of fixed rod 1208. When eccentric wheel 1209 rotates, groove plate 1210 is driven to move. The movement of groove plate 1210 drives knocking rod 1211 to knock the outer wall of annular tube 1104. The limit seat 1212 welded on one side of the mounting plate 1202 is used to limit the movement of the groove plate 1210 and the knocking rod 1211 to a certain extent, ensuring the stability of their movement. The knocking rod 1211 knocking on the annular tube 1104 will cause the annular tube 1104 to vibrate. This vibration can clean up the impurities remaining on the inner wall of the annular tube 1104, avoiding the accumulation and blockage of waste in the annular tube 1104, ensuring the smooth flow of the dust collection mechanism 11, enabling the waste to be collected efficiently, and ensuring the stable operation of the dust collection function.

[0042] See Figure 7 As shown, the clamping mechanism 13 includes a shell 1301 welded to one side of the clamp 7, a piston plate 1302 slides inside the shell 1301, a pressure rod 1303 is fixedly connected to the top of the piston plate 1302, and one end of the pressure rod 1303 passing through the outside of the shell 1301 is fixedly connected to a pressure plate 1304, and a spring C1305 is provided on the outer wall of the pressure rod 1303, and the dust collector head 1105 is connected to the shell 1301 through a connecting pipe 1306.

[0043] See Figure 7 As shown, a gasket is provided at the bottom of the pressing plate 1304, and the gasket is made of rubber material.

[0044] It should be noted that when the dust collection mechanism 11 is working, the dust collector 1103 in the dust collection mechanism 11 is turned on, and a negative pressure environment is formed at the annular tube 1104 at the top of the protective cover 1101 and the dust collection head 1105 connected thereto. Since the dust collection head 1105 is connected to the shell 1301 through the connecting tube 1306, the negative pressure generated at the dust collection head 1105 will be transmitted to the shell 1301. Under the action of the negative pressure, the air in the shell 1301 is extracted and the air pressure is reduced. At this time, the piston plate 1302 is in a state of contact with the shell 1301. Under the action of the pressure difference formed by the negative pressure in the body 1301, the piston plate 1302 slides downward in the shell 1301. The sliding of the piston plate 1302 drives the pressure rod 1303 connected to it to move downward synchronously, thereby causing the pressure plate 1304 to move toward the direction close to the pull plate 1009. As the pressure plate 1304 approaches, the pressure plate 1304 is finally tightly pressed on the top of the pull plate 1009, preventing the clamp 7 from loosening due to the vibration generated by the processing, ensuring the firm clamping of the workpiece during the processing, and effectively improving the processing accuracy.

[0045] See Figure 1 As shown, two groups of symmetrically arranged sliding grooves are opened on the surface of the placement table 3, and the screw rod 5 rotates inside the sliding grooves.

[0046] Working principle: During use, when the clamp 7 needs to be disassembled, the operator manually grabs the pull plate 1009 and pulls it upward. The upward movement of the pull plate 1009 will directly drive the vertical rod 1002 to slide upward in the installation groove 1001. When the vertical rod 1002 moves upward, the rack A1003 will move upward synchronously. The half gear 1004 is installed in the installation groove 1001 through the rotating shaft and meshes with the rack A1003. When the rack A1003 moves upward, it will drive the half gear 1004 to rotate around its rotating shaft. When the half gear 1004 rotates, the guide rod 1005 will rotate with the half gear 1004. When the clamp 7 is installed normally, the guide rod 1005 will exert an extrusion effect on the push plate 1006, so that the insertion rod 1007 is inserted into the clamp When the half gear 1004 rotates, the guide rod 1005 gradually releases the squeeze on the push plate 1006. After the guide rod 1005 releases the squeeze on the push plate 1006, the spring A1010 releases its elastic potential energy, pushing the push plate 1006 to slide in the installation groove 1001. The sliding of the push plate 1006 drives the insertion rod 1007 to move together, and finally the insertion rod 1007 is disengaged from the slot 1008. At this time, the connection between the clamp 7 and the clamp plate 6 is released, and the operator can quickly disassemble the clamp 7 for replacement, thereby achieving the goal of not using complicated tools and tedious operating steps, greatly reducing the labor intensity of the operator and improving the convenience of operation.

[0047] When the fixture 7 is installed, the operator pushes the pull plate 1009 downward, and the downward movement of the pull plate 1009 drives the vertical rod 1002 to slide downward in the installation groove 1001. The rack A1003 on the side wall of the vertical rod 1002 moves downward synchronously with the vertical rod 1002. When the rack A1003 moves downward, it drives the half gear 1004 to rotate around its axis. During the rotation of the half gear 1004, the guide rod 1005 gradually approaches the push plate 1006 and applies an extrusion action to the push plate 1006. When the push plate 1006 is squeezed by the guide rod 1005, it will move toward the stacked airbag 1201 and squeeze the stacked airbag 1201. When the stacked airbag 1201 is squeezed, the gas inside it is transported to the inside of the sleeve 1204 fixed to the side wall of the mounting plate 1202 through the gas pipe 1203. As the gas continues to enter the sleeve 1204, the gas pressure inside the sleeve 1204 continues to increase. When the gas pressure inside the sleeve 1204 increases, it will push the piston rod 1205 to The elastic force of the servo spring B1206 slides in the sleeve 1204, and the movement of the piston rod 1205 drives the rack B1207 to move synchronously. Since the rack B1207 and the eccentric wheel 1209 are engaged with each other, when the rack B1207 moves, it drives the eccentric wheel 1209 to rotate around the bearing at the top of the fixed rod 1208. When the eccentric wheel 1209 rotates, it drives the groove plate 1210 to move. The movement of the groove plate 1210 drives the knocking rod 1211 to knock the outer wall of the annular tube 1104. The limiting seat 1212 welded on one side of the plate 1202 is used to limit the movement of the groove plate 1210 and the knocking rod 1211 to a certain extent, ensuring the stability of their movement. The knocking rod 1211 knocks the annular tube 1104, which causes the annular tube 1104 to vibrate. This vibration can clean up the impurities remaining on the inner wall of the annular tube 1104, preventing waste from accumulating and clogging in the annular tube 1104, ensuring the smooth flow of the dust collection mechanism 11, enabling waste to be collected efficiently, and ensuring the stable operation of the dust collection function;

[0048] When the drill bit 9 is used to drill a hole on a workpiece, the protective cover 1101 covers the processing part, thereby blocking the waste material, preventing the waste material from splashing, and facilitating the absorption of the waste material. At the same time, the vacuum cleaner 1103 is controlled to start, so that the vacuum cleaner 1103 absorbs the waste material such as debris generated during the processing through the dust collection head 1105, so that the waste material enters the inside of the annular tube 1104, and then enters the inside of the collection box 1102 through the dust collection tube 1106 for collection, thereby keeping the working environment clean, reducing the possibility of impurities splashing to the installation part of the clamp 7, avoiding the difficulty of replacing the clamp 7 due to impurities, and allowing the clamp 7 to be quickly put into normal work after replacement, thereby improving the processing quality;

[0049] When the dust collection mechanism 11 is working, the dust collector 1103 in the dust collection mechanism 11 is turned on, and a negative pressure environment is formed at the annular tube 1104 at the top of the protective cover 1101 and the dust collection head 1105 connected thereto. Since the dust collection head 1105 is connected to the shell 1301 through the connecting tube 1306, the negative pressure generated at the dust collection head 1105 will be transmitted to the shell 1301. Under the action of the negative pressure, the air in the shell 1301 is extracted and the air pressure is reduced. At this time, the piston plate 1302 is at a pressure between the external atmospheric pressure and the shell 1301. 1, the piston plate 1302 slides downward in the housing 1301 under the action of the pressure difference formed by the internal negative pressure. The sliding of the piston plate 1302 drives the pressure rod 1303 connected thereto to move downward synchronously, thereby causing the pressure plate 1304 to move toward the direction of approaching the pulling plate 1009. As the pressure plate 1304 approaches, the pressure plate 1304 is finally pressed tightly against the top of the pulling plate 1009, preventing the clamp 7 from loosening due to the vibration generated by the processing, ensuring the stable clamping of the workpiece during the processing, and effectively improving the processing accuracy.
