[0015] Compared with the prior art, the advantages of this application are:

[0016] (1) The present application can wrap and restrict the four end walls of the tool body by opening a mounting groove recess on the turntable, and cooperate with the pressure plate to cover the turntable so that the pressure strip inserted in the pressure plate can abut against the exposed end wall of the tool body to stop the tool body and form an all-round wrapping restriction. With mutual cooperation, the installation firmness of the tool body during actual use can be improved, and the probability of breakage and damage of the tool body during use can be reduced, which improves the durability and stability of the tool during use to a certain extent and helps to extend its service life.

[0017] (2) The pressure plate is connected to the turntable coaxially so that the pressure plate can rotate relative to the turntable. The position of the pressure strip can be adjusted by rotation, which makes it convenient for the staff to disassemble and replace the tool body. When the tool body is replaced, the staff rotates the pressure plate in the opposite direction so that the pressure strip is adjusted to be back against the front of the tool body. The operation is flexible, which is conducive to improving the convenience of the device in actual use.

[0018] (3) A plurality of mounting grooves are arranged around the upper edge of the turntable, and different tool bodies are installed in each mounting groove. By cooperating with the rotation of the first shaft rod, the tool body extending to the right on the right side of the connecting box can be flexibly switched. During use, different tool bodies can be flexibly selected according to the actual processing requirements to perform cutting operations on the material, which is beneficial to improving the flexibility of the device during actual use.

[0019] (4) By slidingly inserting the pressure strip into the pressure plate, the length of the pressure strip extending relative to the pressure plate can be flexibly adjusted according to the actual length of the corresponding tool body. By slidingly adjusting the corresponding pressure strip, it can be adapted to be supported on the front side of the corresponding tool body, which is beneficial to improving the stability and flexibility of the device in reinforcing tool bodies of different models and lengths.

[0020] (5) By firmly connecting the fixing ring to the first shaft rod and respectively abutting the two retaining rings on both sides of the fixing ring against the inner end walls on both sides of the connecting box, it is possible to avoid axial displacement of the first shaft rod when the tool body is squeezed, which is beneficial to ensuring the stability of the tool body during actual use. At the same time, by distributing a plurality of ball bearings between the retaining rings on both sides and the fixing ring, the rolling connection of a large number of ball bearings is beneficial to ensuring the smooth and stable rotation between the fixing ring and the retaining ring.

[0021] (6) By fixing the second shaft rod at the bottom of the connecting box and rotatably installing the connecting box in the bottom box, the connecting box can be rotated relative to the bottom box. The direction of the turntable can be flexibly adjusted according to the actual needs of use. When different forces are applied, the pressure strip can be adjusted to share most of the force for the tool body, which is beneficial to further improve the firmness and stability of the tool body during cutting.

[0022] (7) With the help of the self-locking property of the meshing between the first worm wheel and the first worm, the structural stability of the turntable after the position of the tool body is adjusted can be guaranteed. At the same time, with the help of the self-locking property of the meshing between the second worm wheel and the second worm, the staff can only drive the second worm wheel to rotate by rotating the second worm, and then adjust the direction of the turntable, which is conducive to ensuring the convenience and stability of the device during actual use.

[0023] (8) By circulating the coolant in the hot runner opened in the tool body, the heat generated by the tool body during operation can be quickly dissipated, which is beneficial to further improve the stability of the tool body during operation. By means of the sliding connection between the annular groove and the first channel and the second channel, and the rotational connection between the first through pipe and the first annular cavity, and the rotational connection between the second through pipe and the second annular cavity, the circulation of the coolant will not be affected when the second shaft is rotated and adjusted, which is beneficial to ensure the operating stability of the device.

[0037] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0038] Embodiment 1:

[0039] The present invention provides a cutting tool for a CNC machine tool having a tool head reinforcement structure, see Figure 1 - Fig.11, including a connecting seat 1, a bottom box 101 is fixedly installed on one side of the top of the connecting seat 1, and a connecting box 102 is connected to the top of the bottom box 101, a turntable 103 is arranged on one side of the connecting box 102, a mounting groove 104 is opened at the edge position of the turntable 103 away from the connecting box 102, a tool body 105 extending to the outside is firmly installed in the mounting groove 104 by bolts, a pressure plate 106 is arranged on the side of the turntable 103 away from the connecting box 102, and a pressure strip 107 is inserted in the pressure plate 106 to resist the outer end wall of the tool body 105 away from the connecting box 102.

[0040] During the use of the tool, a plurality of vertically arranged mounting holes are provided on the connecting seat 1, and bolts can be inserted into the mounting holes. The staff can securely mount the device on the CNC machine tool through the bolts, and control the device to move forward, backward, left and right through the CNC machine tool, so that the tool body 105 mounted in the mounting groove 104 on the turntable 103 contacts the material to be processed, and the material is driven to rotate by the CNC machine tool, and moves relative to the tool body 105 during the rotation, so that the tool body 105 can achieve cutting processing on the material. When the tool body 105 is used to cut the material, the tool body 105 is securely mounted in the mounting groove 104. Since the mounting groove 104 is recessed in the turntable 103, this makes the turntable 103 The four inner end walls can wrap and restrict the four end walls corresponding to the tool body 105, and cooperate with the covering of the front pressure plate 106 and the pressure strip 107 inserted on the pressure plate 106, so that the pressure strip 107 can stop the tool body 105 from the front, and cooperate with the wrapping of the installation groove 104, which can not only improve the firmness of the tool body 105 installed in the installation groove 104, but also under the restriction and support of the pressure strip 107, the pressure strip 107 can also support the tool body 105, which is beneficial to improve the firmness of the tool body 105 during actual use, and reduce the probability of breakage and damage of the tool body 105 during actual use, and to a certain extent improve the durability and stability of the tool during use.

[0041] See also Figure 4 and Figure 7The pressure plate 106 is coaxially connected to the turntable 103, and the internal thread of the pressure strip 107 is screwed with a screw 108, and the screw 108 points to the tool body 105. During the use of the tool, the pressure plate 106 is coaxially connected to the turntable 103, which allows the pressure plate 106 to rotate relative to the turntable 103, and the position of the pressure strip 107 is adjusted by rotation. During normal use of the device, the pressure strip 107 is against the front of the tool body 105 to reinforce the tool body 105. When the tool body 105 needs to be replaced, the staff loosens it by twisting the screw 108, and then rotates the pressure plate 106 to drive the pressure strip 107 to rotate, so that the pressure strip 107 deviates from the tool body 1 05, after losing the stop of the pressure strip 107, the tool body 105 located in the installation groove 104 is completely exposed, which is convenient for the staff to disassemble and replace the tool body 105. When the tool body 105 is replaced, the staff rotates the pressure plate 106 in the opposite direction, so that the pressure strip 107 is adjusted and then back-stopped on the front of the tool body 105. Then the staff rotates the screw 108 to make it press against the front of the tool body 105. At this time, the position of the pressure strip 107 is firmly restricted, and with the help of the screw 108, the tool body 105 is further tightened and supported, which can not only ensure the stability of the position of the pressure strip 107, but also further improve the stability of the reinforced tool body 105.

[0042] See also Figure 1 and Figure 7 There are a plurality of mounting grooves 104, which are evenly distributed around the edge of the turntable 103 away from the connecting box 102. The tool bodies 105 installed in the plurality of mounting grooves 104 are different. There are also a plurality of pressure strips 107, which are evenly distributed around the pressure plate 106 and correspond one to one with the plurality of tool bodies 105. A first shaft rod 109 is rotatably installed in the connecting box 102, and the first shaft rod 109 is fixedly connected to the axial position of the turntable 103. A servo motor 2 for driving the first shaft rod 109 to rotate is installed on the connecting box 102.

[0043] During the use of the tool, the plurality of mounting grooves 104 provided on the turntable 103 are distributed around the first shaft 109. By providing the plurality of mounting grooves 104 around the edge of the turntable 103 and installing a different tool body 105 in each mounting groove 104, the tool body 105 extending to the right on the right side of the connection box 102 can be flexibly switched in coordination with the rotation of the first shaft 109. When switching, the staff controls the servo motor 2 to start, drives the first shaft 109 to rotate, and drives the turntable 103 to rotate. During the rotation of the turntable 103, the turntable 103 is rotated by Figure 2Taking the center position as a reference, the tool body 105 that needs to be switched is transferred to the rightmost side of the connecting box 102. After the transfer, the tool body 105 to be used protrudes horizontally to the right on the right side of the connecting box 102 and contacts the material to be processed, which is convenient for cutting operations. According to the processing requirements during actual use, different tool bodies 105 can be flexibly selected to perform cutting operations on the material, which is beneficial to improving the flexibility of the device during actual use.

[0044] During actual use, since the pressure plate 106 is plugged with pressure strips 107 corresponding to multiple tool bodies 105, the front side of each tool body 105 can be abutted and restricted by the corresponding pressure strip 107. Even after the tool body 105 is rotated to adjust its position, it can still be reinforced by the corresponding pressure strip 107, effectively ensuring the stability of the device during flexible use.

[0045] See also Figure 4 The pressure strip 107 is slidably inserted into the pressure plate 106. During the use of the tool, the pressure strip 107 is slidably inserted into the pressure plate 106. This allows the length of the pressure strip 107 extending relative to the pressure plate 106 to be flexibly adjusted according to the actual length of the corresponding tool body 105. By sliding and adjusting the corresponding pressure strip 107, it can be adapted to be supported on the front side of the corresponding tool body 105, which is conducive to further improving the stability and flexibility of the device in reinforcing tool bodies 105 of different models and lengths.

[0046] See also Figure 4 and Fig.10 The first shaft 109 is fixedly sleeved with a first worm gear 201 coaxially arranged therewith, and the outer side of the first worm gear 201 is meshedly connected with a first worm 202, and the driving shaft of the servo motor 2 is coaxially fixedly connected with the first worm 202. During the use of the tool, when the staff controls the turntable 103 to rotate and adjust the position of the tool body 105 through the servo motor 2, the servo motor 2 is powered on and started to drive the first worm 202 coaxially fixed with its driving shaft to rotate, and the first worm 202 is driven by the meshing between the first worm 202 and the first worm wheel 201 to rotate. The first shaft 109 is driven to rotate, providing power for the rotation of the turntable 103. During the transmission of the rotational power, the self-locking property of the meshing between the first worm gear 201 and the first worm 202 allows the first worm gear 201 to rotate when the first worm 202 rotates, and the first worm gear 201 is locked when the first worm 202 does not rotate, thereby ensuring the structural stability of the turntable 103 after the tool body 105 is rotated to adjust the position. There is no need for secondary fixation after the tool body 105 position is adjusted, which can improve the convenience and stability of the device during actual use to a certain extent.

[0047] See also Figure 3 , Figure 4 and Figure 8 A positioning member 3 sleeved on the first shaft rod 109 is installed in the connection box 102, and the positioning member 3 includes a fixing ring 301 sleeved on the outside of the first shaft rod 109, and the fixing ring 301 is firmly connected to the first shaft rod 109 by bolts, and both sides of the fixing ring 301 are provided with a retaining ring 302 movably sleeved on the outside of the first shaft rod 109, and the two retaining rings 302 are tightly fitted with the inner end walls on both sides of the connection box 102 respectively, and a plurality of surrounding balls 303 are rollingly connected between the two retaining rings 302 and the fixing ring 301.

[0048] When the tool is in use, the positioning member 3 is installed on the first shaft rod 109 in the connecting box 102, and a plurality of bolts distributed in a circumferential manner are installed on the fixing ring 301. These bolts penetrate the fixing ring 301 and abut against the outer end wall of the first shaft rod 109, so that the fixing ring 301 can be firmly connected to the first shaft rod 109. Since the two retaining rings 302 arranged on both sides of the fixing ring 301 abut against the inner end walls on both sides of the connecting box 102 respectively, the position of the positioning member 3 is stably restricted in the connecting box 102. With the support of the retaining rings 302 on both sides, the axial displacement of the first shaft rod 109 when the tool body 105 is squeezed can be avoided, which is beneficial to ensuring the stability of the tool body 105 during actual use. By distributing a plurality of balls 303 in a circumferential manner between the retaining rings 302 on both sides and the fixing ring 301, with the help of the rolling connection of many balls 303, it is beneficial to ensure the smooth and stable rotation between the fixing ring 301 and the retaining ring 302.

[0049] See also Figure 1 , Figure 3 , Figure 6 , Fig.10 and Fig.11 A second shaft rod 4 is fixedly installed vertically at the bottom center position of the connecting box 102, and the second shaft rod 4 is rotatably inserted in the center position of the bottom box 101, a slide rail 401 coaxially arranged with the second shaft rod 4 is fixedly installed on the top of the bottom box 101, and a slider 402 fixedly installed at the bottom of the connecting box 102 is rotatably connected in the slide rail 401, a second worm gear 403 is coaxially fixed on the second shaft rod 4 in the bottom box 101, and a second worm 404 is meshingly connected to the outer side of the second worm gear 403, one end of the second worm 404 extends through to the outside of the bottom box 101, and is fixedly connected to a connector 405.

[0050] During the use of the tool, the second shaft 4 is fixedly mounted on the bottom of the connection box 102, and the connection box 102 is rotatably mounted in the bottom box 101, so that the connection box 102 can rotate relative to the bottom box 101. This allows the direction of the turntable 103 to be flexibly adjusted according to actual use requirements during the use of the tool. Figure 1As shown in , when the turntable 103 faces the front, the pressure strip 107 is located in front of the tool body 105, and a more solid abutment restriction can be formed on the front of the tool body 105. This structure is suitable for materials to move from back to front relative to the tool body 105. The relative force of the material on the tool body 105 can be transferred to the pressure strip 107 abutting on the front, as shown in FIG. Fig.10 , Fig.11 As shown in the figure, when the turntable 103 faces the back, the pressure strip 107 is on the back of the tool body 105, and can form a firm abutment restriction on the back of the tool body 105. This structure is suitable for the movement of materials from front to back relative to the tool body 105. The relative force of the material on the tool body 105 can be transferred to the pressure strip 107 abutting on the back. Relying on the rotation of the second shaft 4, the front and rear directions of the turntable 103 can be flexibly adjusted, which can effectively improve the flexibility of the device in actual use.

[0051] The top of the bottom box 101 is fixedly installed with a slide rail 401, and the bottom of the connection box 102 is fixedly installed with a slider 402 rotatably connected to the slide rail 401. With the cooperation of the slide rail 401 and the slider 402, the structural stability of the connection box 102 when rotating relative to the bottom box 101 can be further improved. A second worm gear 403 and a second worm 404 meshing with each other are installed in the bottom box 101. When it is necessary to adjust the direction of the turntable 103, the staff inserts the hexagonal wrench into the connector 405, and drives the second worm 404 with the help of the connection of the connector 405. The rod 404 rotates, and then with the help of the meshing between the second worm 404 and the second worm wheel 403, the second shaft 4 is driven to rotate, providing power for adjusting the direction of the turntable 103. Similarly, with the help of the self-locking property of the meshing between the second worm wheel 403 and the second worm 404, the staff can only drive the second worm wheel 403 to rotate by rotating the second worm 404, and then adjust the direction of the turntable 103. When the second worm 404 is not driven to rotate, the direction of the turntable 103 cannot be changed, which is beneficial to ensure the stability of the tool during actual use.

[0052] See also Figure 3 , Figure 4 and Fig.10A heat dissipation channel is provided in the turntable 103. A ring groove 5 coaxially sleeved on the outside of the first shaft 109 is fixedly installed on one side of the turntable 103 close to the connection box 102, and the ring groove 5 is communicated with the heat dissipation channel. The side of the ring groove 5 close to the connection box 102 is set as an open structure. The ring groove 5 and the connection box 102 are slidably fitted and sealed. The connection box 102 is provided with a first channel 501 and a second channel 502 communicated with the ring groove 5. A first through pipe 503 is fixedly installed at the central axis position of the second shaft 4, and a second through pipe 504 is sleeved on the outside of the first through pipe 503. The first through pipe 503 is The upper end is connected to the first channel 501, the upper end of the second through pipe 504 is connected to the second channel 502, the lower end of the first through pipe 503 is movably connected to the first annular cavity 505 opened in the connecting seat 1, the lower end of the first through pipe 503 is provided with a through hole arranged in the first annular cavity 505, the lower end of the second through pipe 504 is movably connected to the second annular cavity 506 opened in the connecting seat 1, the lower end of the second through pipe 504 is provided with a through hole arranged in the second annular cavity 506, and a water inlet joint 507 connected to the first annular cavity 505 and a water return joint 508 connected to the second annular cavity 506 are fixedly installed on the connecting seat 1.

[0053] During the use of the tool, coolant flows in the heat dissipation channel and the annular groove 5, and the heat generated by the tool body 105 during operation is transferred to the heat dissipation channel opened in the turntable 103. With the help of the circulation of the coolant in the heat dissipation channel, the heat generated by the tool body 105 during operation is quickly discharged, thereby avoiding the tool body 105 from burning due to overheating during cutting.

[0054] The water inlet joint 507 and the water return joint 508 are connected to the coolant circulation supply device. During the coolant circulation process, the coolant with a lower temperature enters the first annular cavity 505 through the water inlet joint 507, then enters the first through-tube 503 through the through hole on the first through-tube 503, and then enters the annular groove 5 through the first channel 501, and then flows in the heat dissipation channel, absorbs the high heat transmitted from the tool body 105 and heats up. The heated coolant flows back to the second through-tube 504 through the second channel 502, and enters the second through-tube 504 through the through hole at the lower end of the second through-tube 504. The high-temperature coolant flows back into the coolant circulation supply device through the return joint 508 in the cavity 506 to cool down and dissipate the heat. With the help of the circulation of the coolant, the heat is quickly discharged to ensure the stability of the working environment of the tool body 105. During the circulation of the coolant, with the help of the rotational connection between the first through pipe 503 and the first annular cavity 505, and the rotational connection between the second through pipe 504 and the second annular cavity 506, the circulation of the coolant will not be affected when the second shaft rod 4 is rotated and adjusted, which is beneficial to ensure the operating stability of the device.

[0055] The above are only the best implementation methods adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
