[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0023] See also Figures 1 to 10 In this embodiment, a quick positioning milling cutter disc mounting structure includes a fixed base plate 1, and the four corners of the top surface of the fixed base plate 1 are fixedly installed with a multi-stage electric telescopic rod 2 for pushing, and the output ends of the multiple multi-stage electric telescopic rods 2 are commonly fixedly installed with a U-shaped mounting frame 3 for fixing. The top surface of the fixed base plate 1 is located on the front and rear sides of the U-shaped mounting frame 3 and is fixedly installed with a first handle 11 for pushing, and the front of the support plate 6 is fixedly installed with a second handle 12 for pushing. The handle structure increases the comfort of use of the device, and the rear side of the inner wall of the U-shaped mounting frame 3 is opened. Two snap-fitting slots 301 are provided, and the inner walls of the snap-fitting slots 301 are snap-fitted with fixed blocks 302 for connection. On one side of the inner wall of the snap-fitting slots 301 close to the fixed blocks 302, spring clips 303 are fixedly installed. The front surfaces of the two fixed blocks 302 are fixedly connected to the rear surfaces of the support plate 6, and the opposite sides of the two corresponding spring clips 303 are respectively in contact with the surfaces of the corresponding fixed blocks 302. The snap-fitting effect of the spring clips 303 ensures the stability of the structure in the support plate 6 during movement. Sliding slots 4 for sliding are provided on the opposite sides of the inner wall of the U-shaped mounting frame 3. The inner walls of the two sliding grooves 4 are jointly fixed with a support plate 6 for supporting the cutter disc through a sliding sliding block 5. A placement groove 7 for clamping the cutter disc is provided at the center of the top surface of the support plate 6. A light-transmitting circular hole 701 for light transmission is provided at the center of the lower side of the inner wall of the placement groove 7, and the inner diameter of the light-transmitting circular hole 701 is smaller than half of the inner diameter of the placement groove 7. The light-transmitting circular hole 701 and the placement groove 7 together form a stepped opening structure. The stepped opening formed by the light-transmitting circular hole 701 and the placement groove 7 can better support the milling cutter disc. A laser emitter 8 for positioning is fixedly installed on the top surface of the fixed base plate 1 directly below the placement groove 7. The fixed base plate 1 is located on the left and right sides of the U-shaped mounting frame 3 and is provided with cleaning components 9 for cleaning.

[0024] Among them, the cleaning component 9 includes a storage box 901 fixedly mounted on one side of the top surface of the fixed base plate 1, and a sealing cover 902 for sealing is clamped on the upper side of the inner wall of the storage box 901, and the surface of the U-shaped mounting frame 3 is located on the opposite sides of the storage box 901 and fixedly mounted with pulling blocks 903 for pulling, the top surface of the U-shaped mounting frame 3 is located on one side of the pulling block 903 and fixedly mounted with a liquid spray shell 904 for spraying liquid, and the liquid spray shell 904 is fixedly mounted on the side close to the support plate 6 with several atomizing nozzles 905 for atomized spraying, and several corresponding atomizing nozzles 905 are all inclined, and the inclination direction is that the side close to the support plate 6 is higher than the side away from the support plate 6, the upward tilt setting of the atomizing nozzle 905 ensures that the alcohol is smoothly sprayed onto the surface of the milling cutter disc, and the bottom surfaces of several pulling blocks 903 are provided with a liquid feeding component 10 for feeding liquid; This device uses the first handle 11 to move the device and combines it with the horizontal state of the installation body to ensure that the milling disc is "horizontally upward" when the fixed base plate 1 is placed, thereby avoiding the installation deviation of the milling disc caused by tilted placement from the basic level. The laser emitter 8 design of this device realizes dual positioning. On the one hand, it ensures that the U-shaped mounting frame 3 is located directly below the installation body, providing a reference for the precise pushing of the multi-stage electric telescopic rod 2. On the other hand, the laser acts on the milling disc in the placement slot 7 through the light-transmitting circular hole 701 to ensure that the milling disc is aligned with the center of the installation body, solving the problem of "visual deviation" in traditional manual alignment and significantly improving the coaxiality and horizontality of the installation.

[0025] The protrusion in the placement groove 7 is engaged with the milling cutter disc, further strengthening the positioning effect, preventing the milling cutter disc from shifting during the pushing process, and ensuring the consistency of the installation position.

[0026] Among them, the liquid delivery component 10 includes a pull rod 1001 fixedly installed on the bottom surface of the pull block 903, and a pushing plate 1002 for pushing is fixedly installed at the lower end of the pull rod 1001, and a piston cylinder 1003 for pumping liquid is slidably installed on the surface of the pushing plate 1002. The surfaces of the pull rods 1001 pass through the upper side of the inner wall of the piston cylinder 1003 and extend to the top of the piston cylinder 1003. A limiting ring 1004 for limiting is fixedly installed on the lower side of the inner wall of the piston cylinder 1003, and a first connecting hose 1005 for transportation is fixedly installed on the lower side of the surface of the piston cylinder 1003, and a second connecting hose 1006 for transportation is fixedly installed on the surface of the piston cylinder 1003 below the first connecting hose 1005. The first connecting hose 10 A check valve 13 for non-return is fixedly installed on one side of the surface of 05 close to the storage box 901 and on the side of the surface of the second connecting hose 1006 close to the liquid spraying shell 904, and the non-return directions of the two check valves 13 are set in opposite directions. One end of the first connecting hose 1005 close to the storage box 901 passes through the upper surface of the storage box 901 and extends to the lower side of the inner wall of the storage box 901, and the upper end of the second connecting hose 1006 is fixedly connected to the surface of the corresponding liquid spraying shell 904. The first connecting hose 1005 is arranged below the limit ring 1004, and the second connecting hose 1006 is arranged at the lowest side of the surface of the piston cylinder 1003. The arrangement of the two check valves 13 can ensure that the two hoses are one for suction and one for discharge, thereby ensuring the normal use function of the device; The support plate 6 can be pulled out or pushed in by the second handle 12, so that the placement of the milling cutter disc does not need to be carried out deep inside the U-shaped mounting frame 3, solving the traditional problem of "difficult placement in a narrow space". A single person can complete the placement and take-out, reducing labor costs. In addition, the multi-stage electric telescopic rod 2 in the device replaces manual lifting to realize automatic pushing of the milling cutter disc, avoiding installation deviation caused by shaking or uneven force during manual lifting, and reducing the labor intensity of the operator.

[0027] A piston block 1007 is movably mounted on the inner wall of the piston cylinder 1003 above the limiting ring 1004. The surfaces of several piston blocks 1007 are in close contact with the inner wall of the corresponding piston cylinder 1003. The inner wall of the storage box 901 is filled with anhydrous alcohol. The top surface of the piston block 1007 is fixedly connected to the bottom surface of the push plate 1002 via a damping spring 1008. When the U-shaped mounting frame 3 of the device moves up and down, the anhydrous alcohol is automatically triggered to be sprayed out through the pull rod 1001, piston cylinder 1003, damping spring 1008 and other structures, ensuring that the alcohol is inhaled when rising and atomized and sprayed out when descending. No additional operation is required, which solves the process redundancy problem of the traditional "separate cleaning after installation".

[0028] In addition, the alcohol usage of the device is controllable. The design of the damping spring 1008 reduces the amount of alcohol absorbed. The piston block 1007 is pushed to absorb the liquid only after it is fully expanded. Combined with the atomizing nozzle 905, it can effectively dissolve pollutants such as grease and cutting fluid residues, while avoiding excessive waste, taking into account both cleaning effect and economy.

[0029] The working principle of the above embodiment is: When the device is in use, the operator needs to use the first handle 11 to move the entire device to the bottom of the shaft of the installation body. Since the installation body is in a horizontal state, the horizontal upward effect of the milling cutter disc can be ensured when the fixed base plate 1 is placed, thereby ensuring the installation quality of the milling cutter disc. The laser emitter 8 can ensure that the U-shaped mounting frame 3 is located directly below the installation body, which is convenient for pushing the multi-stage electric telescopic rod 2 in the later stage. The laser emitter 8 of this device is located directly below the support plate 6, and is also located directly below the placement groove 7 and the light-transmitting circular hole 701. After the milling cutter disc is placed in the placement groove 7 in the support plate 6, the direct installation effect of the milling cutter disc and the installation body can be ensured; After the position of the laser emitter 8 is fixed, the support plate 6 is pulled out by the second handle 12, and then the milling cutter disc to be installed is placed in the placement groove 7. The protrusion in the placement groove 7 can better fit the milling cutter disc to ensure the positioning effect of the installation of the milling cutter disc. After the milling cutter disc is installed, the support plate 6 is pushed into the U-shaped mounting frame 3 by the second handle 12, and then the milling cutter disc in the U-shaped mounting frame 3 is pushed upward by the multi-stage electric telescopic rod 2, thereby achieving the positioning installation effect of the milling cutter disc; In the process of the U-shaped mounting frame 3 moving upward, the pull rod 1001 under the pull block 903 starts to move. Because the U-shaped mounting frame 3 is located at the lower side, the pull rod 1001 squeezes the push plate 1002 to put the damping spring 1008 in a squeezed state. When the pull rod 1001 moves upward, the piston block 1007 will not move in time. In the process of the movement of the pull rod 1001, the damping spring 1008 needs to be fully opened to ensure that the movement of the piston block 1007 produces a lotion effect. This ensures that the inhaled anhydrous alcohol will not be too much. When the milling cutter After the disc is installed, the U-shaped mounting frame 3 will move downward, which will guide the liquid in the piston cylinder 1003 into the spray shell 904 through the second connecting hose 1006, and then spray it out through the atomizing nozzle 905. Due to the expansion of the damping spring 1008, less alcohol will be drawn into the piston cylinder 1003. In the process of the U-shaped mounting frame 3 moving downward, the sprayed alcohol will clean the milling cutter disc without causing excessive waste. Spraying alcohol on the milling cutter disc can dissolve organic pollutants such as grease and cutting fluid residues, thereby ensuring the later use effect of the milling cutter disc.

[0030] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
