They are designed according to the workpiece machining process. Surface-forming tools can be categorized in several ways, including tools for machining various external surfaces, hole-making tools, thread-making tools, gear-making tools, and parting tools.

[0020] Please see Figure 1-7 In this embodiment of the invention, a machine tool tool support mechanism includes an assembly opening and closing component 1 and a tool changing mechanism 5.

[0024] In the embodiments of the present invention, when it is needed for use, the duct compartment 106 is sleeved on the inner side of the slotted horizontal box 105. When the tool is needed for use, the built-in cylinder 107 on the top side of the duct compartment 106 outputs power to drive the output end to run. When the built-in cylinder 107 outputs power to run, the opening and closing plate 108 retracts the duct compartment 106 to achieve the effect of opening.

[0025] The translation adjustment component 2 includes a bolt base plate 201, a gearbox 202, a drive motor 203, a drive gear 204, a driven gear 205, a translation screw 206, a threaded moving block 207, and a sliding base 208. The bolt base plate 201 is bolted to one end of the duct compartment 106.

The drive gear 204 is provided at the output end of the drive motor 203, and the driven gear 205 is provided at the output end of the drive gear 204.

[0026] In an embodiment of the present invention, after the device is turned on, the drive motor 203 on the outer side of the gearbox 202 outputs power to drive the output end to run. When the drive motor 203 outputs power, it can drive the drive gear 204 at the output end to rotate. When the drive gear 204 rotates, it can drive the driven gear 205 meshed with the output end to rotate.

[0027] The output end of the driven gear 205 is provided with a translation screw 206, and a threaded moving block 207 with threaded connection is provided on the outer side of the translation screw 206. A sliding base 208 is provided on the lower outer side of the threaded moving block 207.

[0028] In an embodiment of the present invention, when the driving gear 204 and the driven gear 205 are engaged in transmission, the output end of the driven gear 205 can drive the translation screw 206 to rotate. When the translation screw 206 rotates, it can drive the threaded moving block 207 and the sliding base 208 to slide to the target position on the slotted horizontal box 105.

[0029] The lifting and mounting mechanism 3 includes a bolt side strip 301, a through sleeve block 302, a slotted frame 303, a lifting screw assembly 304, a lifting block 305, a sleeve block 306, a hydraulic telescopic arm 307, a bushing seat 308, a rotary motor 309, a rotary spline seat 3010, a tool hole disc 3011, a positioning spline 3012, a side strip 3013, a positioning hole plate 3014, and a circular rubber ring 3015. The bolt side strip 301 is bolted to the outer side of the sliding base 208. The bolt side strip 301 is provided with a bolt-assembled through sleeve block 302 on the outer side, and the through sleeve block 302 is provided with a slotted frame 303 on the inner side. The slotted frame 303 is provided with a lifting screw assembly 304 on the inner side, and the lifting screw assembly 304 is provided with a threaded lifting block 305 on the outer side.

[0030] In an embodiment of the present invention, after the threaded moving block 207 and the sliding base 208 slide to the target position on the slotted horizontal box 105, they also drive the lifting mounting mechanism 3 to slide to the target position. Then, the output end of the slotted frame 303 outputs power to drive the lifting block 305 at the output end to lift and move, so that the lifting block 305 is adjusted to the target height.

[0031] The inner end of the lifting block 305 is provided with a sleeve block 306, and the inner sides of both ends of the sleeve block 306 are provided with hydraulic telescopic arms 307. The output end of the hydraulic telescopic arm 307 is provided with a bushing seat 308. The inner side of the bushing seat 308 is provided with a rotary motor 309, and the output end of the rotary motor 309 is provided with a rotary spline seat 3010.

[0032] In an embodiment of the present invention, after the lifting block 305 is adjusted to the target height, the output end on the sleeve block 306 outputs power to drive the output end to run. In this way, the hydraulic telescopic arm 307 can be adjusted to a suitable length position after the output end runs. After the hydraulic telescopic arm 307 is adjusted to a suitable length position, the rotary motor 309 on the inner side of the bushing seat 308 is started to output power to drive the output end to rotate, so that the rotary spline seat 3010 rotates to a suitable angle position.

[0033] The outer end of the rotary spline seat 3010 is provided with a cutting hole disk 3011, and the inner side of the cutting hole disk 3011 is provided with a positioning spline 3012. The outer side of the cutting hole disk 3011 is provided with a side strip 3013, one end of the side strip 3013 is provided with a positioning hole plate 3014, and the inner side of the positioning hole plate 3014 is provided with a circular rubber ring 3015.

[0034] In the embodiments of the present invention, since both the tool hole disk 3011 and the positioning hole plate 3014 have a porous annular distribution, the circular rubber ring 3015 on the positioning hole plate 3014, together with the positioning spline 3012 on the tool hole disk 3011, can effectively install and support the tool sample 4, preventing the risk of the tool falling.

[0035] The tool changing mechanism 5 includes a slotting hinge frame 501, a camera 502, an electric hinge base 503, a mechanical telescopic arm 504, a mechanical swing arm 505, and a mechanical clamp 506. The slotting hinge frame 501 is bolted to one end of the slotting horizontal box 105. The camera 502 is located below the slotting hinge frame 501. Electric hinge bases 503 are located at both ends of the slotting hinge frame 501. A mechanical telescopic arm 504 is located at one end of the electric hinge base 503. A mechanical swing arm 505 is located at one end of the mechanical telescopic arm 504. A mechanical clamp 506 is located at one end of the mechanical swing arm 505.

[0036] In an embodiment of the present invention, after the rotating spline seat 3010 is rotated to a suitable angle position, the camera 502 below the slotted hinge frame 501 accurately captures the equipment, and the command is input to the electric hinge seat 503 for operation. After the electric hinge seat 503 is in operation, the hinge transmission between the mechanical telescopic arm 504 and the mechanical swing arm 505 is activated, causing the mechanical clamp 506 to clamp the tool sample 4 and disengage it from the lifting and mounting mechanism 3 and install it onto the machine tool.

[0037] The working principle of this invention is as follows: In use, the pad 101 is placed in the machine tool's operating position. The pad 101 is then fixed in place using a long screw 102 and a hexagonal nut 103. A vertical support 104 is used to install the slotted horizontal box 105 on the top side of the pad 101. When needed, the duct chamber 106 is fitted onto the inner side of the slotted horizontal box 105. When a tool is needed, the built-in cylinder 107 on the top side of the duct chamber 106 outputs power to drive the output end. When the built-in cylinder 107 outputs power, the opening / closing plate 108 retracts the duct chamber 106, achieving the opening effect. After the equipment is opened, the gear... The drive motor 203 on the outer side of the engine box 202 outputs power to drive the output end to operate. When the drive motor 203 outputs power, it can drive the drive gear 204 at the output end to rotate. When the drive gear 204 rotates, it can drive the driven gear 205 meshed with at the output end to rotate. When the drive gear 204 and the driven gear 205 are meshing and transmitting power, the output end of the driven gear 205 can drive the translation screw 206 to rotate. When the translation screw 206 rotates, it can drive the threaded moving block 207 and the sliding base 208 to slide to the target position on the slotted horizontal box 105. When the threaded moving block 207 and the sliding base 208 slide to the target position on the slotted horizontal box 105, they can drive the threaded moving block 207 and the sliding base 208 to slide to the target position on the slotted horizontal box 105. Then, the lifting and mounting mechanism 3 is slid to the target position. Next, the output end of the slotted frame 303 outputs power to drive the lifting block 305 at the output end to move up and down, adjusting the lifting block 305 to the target height. Once the lifting block 305 is at the target height, the output end of the mounting block 306 outputs power to drive the output end to move. This allows the hydraulic telescopic arm 307 to be adjusted to a suitable length position after the output end has moved. After the hydraulic telescopic arm 307 is adjusted to the suitable length position, the rotary motor 309 on the inner side of the bushing seat 308 outputs power to drive the output end to rotate, causing the rotating spline seat 3010 to rotate to a suitable angle position. When the rotating spline seat 3010 rotates... Once the appropriate angle is reached, the camera 502 below the slotted hinge frame 501 accurately captures images of the equipment, and the command is input to the electric hinge base 503 for operation. After the electric hinge base 503 operates, the hinge transmission between the mechanical telescopic arm 504 and the mechanical swing arm 505 causes the mechanical clamp 506 to hold the tool sample 4, detach it from the lifting and mounting mechanism 3, and install it onto the machine tool. Since both the tool hole plate 3011 and the positioning hole plate 3014 have a multi-hole annular distribution, the circular rubber ring 3015 on the positioning hole plate 3014, together with the positioning spline 3012 on the tool hole plate 3011, can effectively install and support the tool sample 4, preventing the risk of the tool falling and causing damage.
