[0034] Referring to Figure 3 As shown in the figure, the outer wall of the plug rod 1007 is sleeved with a spring A 1010, one end of the spring A 1010 is fixedly connected to one side of the push plate 1006, and the other end of the spring A 1010 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 up, the upward movement of the pull plate 1009 directly drives the vertical rod 1002 to slide upward in the mounting slot 1001, when the vertical rod 1002 moves upward, the rack A1003 will move upward synchronously, the half gear 1004 is installed in the mounting slot 1001 through the rotating shaft, and is in mesh 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 normally installed, the guide rod 1005 will exert a pressing action on the push plate 1006, so that the insertion rod 1007 is inserted into the insertion slot 1008 on one side of the clamp 7, achieving the fixation of the clamp 7, when the half gear 1004 rotates, the guide rod 1005 will gradually release the pressing action on the push plate 1006, after the guide rod 1005 releases the pressing action on the push plate 1006, the spring A1010 will release its elastic potential energy and push the push plate 1006 to slide in the mounting slot 1001, the sliding of the push plate 1006 will drive the insertion rod 1007 to move together, finally making the insertion rod 1007 disengage from the insertion slot 1008, at this time, the connection between the clamp 7 and the clamp plate 6 is released, the operator can quickly disassemble the clamp 7 for replacement, thereby realizing the need to use complex tools and tedious operation steps, greatly reducing the labor intensity of the operator and improving the operation convenience.

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

[0037] Referring to Figure 6 As shown, the dust collection head 1105 is provided in multiple groups, and the multiple groups of dust collection heads 1105 are distributed in a circumferential array along the outer wall of the annular pipe 1104.

[0038] It should be noted that when the drill bit 9 is used to drill the workpiece, the protective cover 1101 covers the machining position, thereby being able to block the waste, avoid the waste from splashing, and facilitate the absorption of the waste. At the same time, the control of the activation of the dust collector 1103 enables the dust collector 1103 to absorb the waste such as the debris generated during the machining through the dust suction head 1105, so that the waste enters the inside of the annular pipe 1104, and then enters the inside of the collection box 1102 through the dust suction pipe 1106 for collection, thereby keeping the working environment clean, reducing the possibility of impurities splashing to the clamping fixture 7 mounting position, avoiding the difficulty in replacing the clamping fixture 7 due to impurities, enabling the clamping fixture 7 to be quickly put into normal work after replacement, and improving the machining quality.

[0039] Referring to Figures 5 to 7 As shown, the knocking mechanism 12 includes a laminated air bag 1201 installed in the installation groove 1001, one side of the drill bit 9 is welded with a mounting plate 1202, the laminated air bag 1201 and the mounting plate 1202 are communicated through a gas conveying pipe 1203, the side wall of the mounting plate 1202 is fixedly installed with a sleeve pipe 1204, the inside of the sleeve pipe 1204 is slidably provided with a piston rod 1205, the outer wall of the piston rod 1205 is sleeved with a spring B 1206, one end of the piston rod 1205 penetrating out of the inside of the sleeve pipe 1204 is fixedly connected with a rack B 1207, the inner wall of the mounting plate 1202 is welded with a fixed rod 1208, the top end of the fixed rod 1208 is rotatably provided with an eccentric wheel 1209 through a bearing, the top of the eccentric wheel 1209 is rotatably provided with a groove plate 1210, one end of the groove plate 1210 is fixedly connected with a knocking rod 1211, one side of the mounting plate 1202 is welded with a limiting seat 1212.

[0040] Referring to Figure 6 As shown, one side of the knocking rod 1211 is provided in a spherical shape, and the spherical shape is made of an elastic material.

[0041] It needs to be explained that when the installation operation of the clamp 7 is carried out, the operator pushes the pull plate 1009 downward, the downward movement of the pull plate 1009 drives the vertical rod 1002 to slide downward in the installation slot 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 rotating shaft, in the rotating process of the half gear 1004, the guide rod 1005 gradually approaches the push plate 1006 and exerts a pressing force on the push plate 1006, when the push plate 1006 is pressed by the guide rod 1005, it moves to the direction of the stacked air bag 1201 and presses the stacked air bag 1201, when the stacked air bag 1201 is pressed, the gas in it is transported to the inside of the sleeve 1204 fixed on the side wall of the installation plate 1202 through the gas conveying pipe 1203, as the gas continuously enters the sleeve 1204, the gas pressure in the sleeve 1204 continuously increases, when the gas pressure in the sleeve 1204 increases, it drives the piston rod 1205 to slide in the sleeve 1204 against the elastic force of the spring B1206, the movement of the piston rod 1205 drives the rack B1207 to move synchronously, as the rack B1207 is engaged with the eccentric wheel 1209, when the rack B1207 moves, it drives the eccentric wheel 1209 to rotate around the bearing at the top end 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 pipe 1104, the limiting seat 1212 welded on one side of the installation plate 1202 is used for limiting the movement of the groove plate 1210 and the knocking rod 1211 to a certain extent, so as to ensure the stability of the movement, the knocking of the knocking rod 1211 on the annular pipe 1104 makes the annular pipe 1104 vibrate, this vibration can clean the impurities remaining on the inner wall of the annular pipe 1104, avoid the accumulation of waste in the annular pipe 1104 to block it, ensure the smoothness of the dust collection mechanism 11, so that the waste can be collected efficiently, and ensure the stable operation of the dust collection function.

[0042] Referring to Figure 7 As shown in the figure, the pressing mechanism 13 includes the shell 1301 welded on one side of the clamp 7, the piston plate 1302 slides in the inside of the shell 1301, the top of the piston plate 1302 is fixedly connected with the pressing rod 1303, one end of the pressing rod 1303 penetrating out of the outside of the shell 1301 is fixedly connected with the pressing plate 1304, the outer wall of the pressing rod 1303 is sleeved with the spring C1305, the dust collection head 1105 is communicated with the shell 1301 through the connecting pipe 1306.

[0043] Referring to Figure 7 As shown in the figure, the bottom of the pressing plate 1304 is provided with a gasket made of rubber material.

[0044] It should be noted that when the dust collection mechanism 11 works, the dust collector 1103 in the dust collection mechanism 11 is turned on, a negative pressure environment is formed at the annular pipe 1104 at the top end of the protective cover 1101 and the dust collection head 1105 communicated therewith, and the negative pressure generated at the dust collection head 1105 is transmitted to the shell 1301 since the dust collection head 1105 is connected to the shell 1301 through the connecting pipe 1306. Under the action of the negative pressure, the air in the shell 1301 is sucked out, the air pressure is reduced, and at this time, the piston plate 1302 slides downward in the shell 1301 under the pressure difference formed by the external atmospheric pressure and the negative pressure in the shell 1301. The sliding of the piston plate 1302 drives the pressure rod 1303 connected thereto to move downward synchronously, and then the pressing plate 1304 moves toward the direction close to the pull plate 1009. With the approach of the pressing plate 1304, the pressing plate 1304 is finally tightly pressed on the top of the pull plate 1009, preventing the clamp 7 from loosening due to vibration generated during machining, and ensuring the stable clamping of the workpiece during machining, effectively improving the machining precision.

[0045] Referring to Figure 1 As shown in the drawings, the surface of the placement table 3 is provided with two groups of symmetrically arranged sliding grooves, and the screw rod 5 rotates in the interior of the sliding grooves.

[0046] Working principle: when it is necessary to disassemble the clamp 7 during use, the operator manually holds the pull plate 1009 and pulls it upward, and the upward movement of the pull plate 1009 directly drives the vertical rod 1002 to slide upward in the mounting groove 1001. When the vertical rod 1002 moves upward, the rack A 1003 moves upward synchronously. The half gear 1004 is installed in the mounting groove 1001 through a rotating shaft and is in mesh with the rack A 1003. When the rack A 1003 moves upward, it drives the half gear 1004 to rotate around its rotating shaft. When the half gear 1004 rotates, the guide rod 1005 rotates together with the half gear 1004. When the clamp 7 is normally installed, the guide rod 1005 exerts a pressing action on the push plate 1006, so that the insertion rod 1007 is inserted into the insertion groove 1008 on one side of the clamp 7, thereby achieving the fixation of the clamp 7. When the half gear 1004 rotates, the guide rod 1005 gradually releases the pressing action on the push plate 1006. After the guide rod 1005 releases the pressing action on the push plate 1006, the spring A 1010 releases its elastic potential and pushes the push plate 1006 to slide in the mounting groove 1001. The sliding of the push plate 1006 drives the insertion rod 1007 to move together, and finally makes the insertion rod 1007 disengage from the insertion groove 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 installation of the clamp 7 without the use of complex tools and tedious operation steps, greatly reducing the labor intensity of the operator and improving the convenience of operation.

[0047] When the installation operation of the clamp 7 is performed, the operator pushes the pull plate 1009 downward, 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 rotating shaft, during the rotation of the half gear 1004, the guide rod 1005 gradually approaches the push plate 1006 and exerts a pressing force on the push plate 1006, when the push plate 1006 is pressed by the guide rod 1005, it moves towards the stacked air bag 1201 and presses the stacked air bag 1201, when the stacked air bag 1201 is pressed, the gas in it is transported to the inside of the sleeve 1204 fixed on the side wall of the installation plate 1202 through the gas conveying pipe 1203, as the gas continuously enters the sleeve 1204, the gas pressure in the sleeve 1204 continuously increases, when the gas pressure in the sleeve 1204 increases, it drives the piston rod 1205 to slide in the sleeve 1204 against the elastic force of the spring B1206, the movement of the piston rod 1205 drives the rack B1207 to move synchronously, since the rack B1207 and the eccentric wheel 1209 are in mesh with each other, when the rack B1207 moves, it drives the eccentric wheel 1209 to rotate around the bearing at the top end 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 pipe 1104, the limiting seat 1212 welded on one side of the installation plate 1202 is used to limit the movement of the groove plate 1210 and the knocking rod 1211 to a certain extent, to ensure the stability of their movement, the knocking of the knocking rod 1211 on the annular pipe 1104 causes the annular pipe 1104 to vibrate, this vibration can clean the impurities remaining on the inner wall of the annular pipe 1104, avoid the accumulation of waste in the annular pipe 1104 to block it, ensure the smoothness of the dust collection mechanism 11, so that the waste can be collected efficiently, and ensure the stable operation of the dust collection function;

[0048] When the drill bit 9 is used to drill the workpiece, the protective cover 1101 covers the machining position, thereby blocking the waste, avoiding the waste from splashing, and facilitating the absorption of the waste, at the same time, the dust collector 1103 is controlled to start, so that the dust collector 1103 absorbs the waste such as chips generated during machining through the dust collection head 1105, so that the waste enters the inside of the annular pipe 1104, and then enters the inside of the collection box 1102 through the dust collection pipe 1106 for collection, thereby keeping the working environment clean, reducing the possibility of impurities splashing into the installation position of the clamp 7, avoiding the difficulty of replacing the clamp 7 caused by impurities, so that the clamp 7 can be quickly put into normal work after replacement, and the machining quality is improved;

[0049] When the dust collection mechanism 11 works, the dust collector 1103 in the dust collection mechanism 11 is turned on, a negative pressure environment is formed at the annular pipe 1104 at the top end of the protective cover 1101 and the dust collection head 1105 communicated therewith, and the negative pressure generated at the dust collection head 1105 is transmitted to the shell 1301 since the dust collection head 1105 is connected to the shell 1301 through the connecting pipe 1306. Under the action of the negative pressure, the air in the shell 1301 is sucked out, the air pressure is reduced, at this time, the piston plate 1302 slides downward in the shell 1301 under the pressure difference formed by the external atmospheric pressure and the negative pressure in the shell 1301, the sliding of the piston plate 1302 drives the pressure rod 1303 connected thereto to move downward synchronously, and then the pressing plate 1304 moves toward the direction of being close to the pull plate 1009, with the close of the pressing plate 1304, the pressing plate 1304 is finally tightly pressed on the top of the pull plate 1009, preventing the clamp 7 from being loose due to the vibration generated in the machining, and ensuring the stable clamping of the workpiece in the machining process, effectively improving the machining precision.
