DETAILED DESCRIPTION

[0045] 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. Example

[0046] See also Figure 1-2 A crawler rapid milling machine tool for an excavator includes a bed 1 and a hydraulic cylinder 2 installed at one end of the bed 1, a connecting frame 3 is installed at the lower end of the hydraulic cylinder 2, a milling belt 4 is rotatably connected to the lower end of the connecting frame 3, and a plurality of squeezing devices 7 are arranged inside the milling belt 4. The squeezing device 7 includes a first piston cylinder 71 installed at one end of the connecting frame 3, a first piston column 72 is slidably connected to the lower end of the first piston cylinder 71, and the first piston column 72 is used to squeeze the lower end of the milling belt 4 to deform;

[0047] The interior of the connecting frame 3 is also rotatably connected to a drive shaft 9, and a plurality of first telescopic columns 10 are installed on the outer surface of the drive shaft 9. A transmission plate 11 is installed at one end of the first telescopic column 10, and the transmission plate 11 abuts against the milling belt 4;

[0048] The outer surface of the connecting frame 3 is also provided with several trigger devices 5 in sequence. The trigger device 5 includes a square frame 51 installed on the outer surface of the connecting frame 3. The first trapezoidal column 52 and the second trapezoidal column 55 are slidably connected on both sides of the square frame 51. Two cavities are provided inside the square frame 51. The first trapezoidal column 52 and the second trapezoidal column 55 are respectively slidably connected in the cavities. One end of the two cavities is provided with a first tube 54 and a second tube 57 respectively. The first tube 54 and the second tube 57 are used to squeeze the liquid stored in each cavity into the interior of the first piston cylinder 71.

[0049] Due to the uneven shape of the crawler, the existing excavator crawler can only be milled manually when it needs to be milled, which has a low milling efficiency. Alternatively, five-axis CNC machine tools can be used for milling, but the milling cost is high and the crawler size does not require high precision. Therefore, the existing excavator crawler milling device cannot quickly mill the excavator crawler.

[0050] according to Figure 1 As shown, a ram is also installed on the upper end of the bed 1, and a fixture is installed above the ram. The part 12 is placed on the fixture, and then the connecting frame 3 and the milling belt 4 are driven downward by the hydraulic cylinder 2. Figure 2 and Figure 3 As shown, the second trapezoidal column 55 and the first trapezoidal column 52 protrude from the lower end of the milling belt 4, so that several second trapezoidal columns 55 and the first trapezoidal columns 52 are in contact with the upper end surface of the part 12, and the part 12 is used to squeeze the first trapezoidal column 52 and the second trapezoidal column 55 to slide upward, so that the first trapezoidal column 52 and the second trapezoidal column 55 squeeze the liquid inside the square frame 51 into the inside of the first piston cylinder 71, and the first piston column 72 is pushed downward by the liquid inside the first piston cylinder 71. The first piston column 72 pushes the milling belt 4 downward to deform, so that the shape of the lower end of the milling belt 4 is changed by using several first piston columns 72, so that the shape of the lower end of the milling belt 4 is adapted to the upper end surface of the part 12, so that the changed milling belt 4 can mill the upper end surface of the part 12, thereby realizing automatic adjustment of the milling belt 4 to adapt to the upper end surface of the part 12, thereby realizing automatic milling and improving milling efficiency;

[0051] It should be noted that a drive shaft 9 is rotatably connected to the interior of the milling belt 4, and a motor is connected to one side of the drive shaft 9. The motor drives the drive shaft 9 to rotate, and the drive shaft 9 drives the first telescopic column 10 and the transmission plate 11 to rotate. The transmission plate 11 engages with the inner wall of the milling belt 4, thereby driving the milling belt 4 to rotate through the transmission plate 11. When the first piston column 72 squeezes the lower end of the milling belt 4 to change the shape of the lower end of the milling belt 4, the milling belt 4 squeezes the transmission plate 11 and the first telescopic column 10, and the first telescopic column 10 contracts, thereby causing the milling belt 4 to change its shape downward.

[0052] A pressure plate 73 is mounted on the lower end of the first piston column 72, and the pressure plate 73 is used to squeeze the lower end of the milling belt 4 to deform;

[0053] A dust suction device 8 is also installed at the lower end of the connecting frame 3. The dust suction device 8 includes a steel pipe 84 connected to the lower end of the connecting frame 3. The lower end of the steel pipe 84 is installed with a third piston cylinder 81. One end of the third piston cylinder 81 is slidably connected to a third piston column 82. One end of the third piston column 82 is installed with a dust suction head 83.

[0054] A pressure plate 73 is installed at the lower end of the first piston column 72, and the width of the pressure plate 73 is adapted to the width of the milling belt 4;

[0055] according to Figure 1 As shown, a dust suction head 83 is provided at one end of the milling belt 4 , and the dust suction head 83 sucks the dust generated by the milling of the milling belt 4 . Example

[0056] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-4 A connecting sleeve 75 is provided between each two first piston columns 72, and a slide plate 74 is slidably connected to both ends of the connecting sleeve 75, and the slide plate 74 is hinged to the first piston column 72;

[0057] An air bag 76 is installed at the lower end of the connecting sleeve 75 , and the air bag 76 is used to abut against the milling belt 4 .

[0058] There is a gap between each two first piston rods 72, so the milling belt 4 that is not squeezed by the first piston rod 72 cannot completely fit the upper end surface of the part 12. Therefore, an air bag 76 is provided between the two first piston rods 72. Figure 4 As shown, when the two first piston columns 72 slide downward, the connecting sleeve 75 is driven to slide downward by the two first piston columns 72, so that the airbag 76 at the lower end of the connecting sleeve 75 contacts the milling belt 4. Since the airbag 76 is adapted to the gap, when the airbag 76 and the first piston column 72 squeeze the milling belt 4, the deformed milling belt 4 can completely adapt to the upper end surface of the part 12, so that the milling belt 4 can better mill the part 12, thereby reducing the situation of missing milling;

[0059] It should be noted that, since the downward sliding distances of each two first piston columns 72 are different, slide plates 74 are slidably connected to both ends of the connecting sleeve 75 , and the slide plates 74 are hinged to the first piston columns 72 . Example

[0060] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-6A second piston cylinder 77 is further installed inside the milling belt 4. A second piston column 78 is slidably connected to the interior of the second piston cylinder 77. The second piston column 78 passes through the lower end of the second piston cylinder 77. A second telescopic column 79 is installed at the lower end of the second piston cylinder 77. A buckling plate 80 is installed at the lower end of the second telescopic column 79. The buckling plate 80 is used to abut against the airbag 76.

[0061] An adjusting device 6 is also installed inside the milling belt 4. The adjusting device 6 includes a square box 61 installed on one side of the connecting frame 3. Two locking devices are provided inside the square box 61.

[0062] The locking device includes a regulating chamber 62 disposed within a square box 61. A first tube 54 is used to transfer liquid to the regulating chamber 62. A first one-way valve 63 is also disposed within the square box 61. The first one-way valve 63 is located at the lower end of the regulating chamber 62. A third tube 64 is also installed at the lower end of the square box 61. The upper end of the third tube 64 is connected to the lower end of the first one-way valve 63, and the lower end of the third tube 64 is connected to the interior of the first piston cylinder 71.

[0063] The interior of the regulating chamber 62 is slidably connected to a sealing plate 18, the upper end of the sealing plate 18 is slidably connected to a second column 68, the upper end of the second column 68 is mounted with a first column 67, and the second column 68 and the sealing plate 18 are connected via a third spring 66;

[0064] The diameter of the first pillar 67 is smaller than the diameter of the second pillar 68;

[0065] A pull plate 17 is installed at one end of the first one-way valve 63, and the pull plate 17 is connected to the sealing plate 18;

[0066] A push post 69 is slidably connected to one side of the adjustment cavity 62. The push post 69 passes through one side of the connecting frame 3. A protrusion 70 is installed at the lower end of the push post 69. The protrusion 70 is used to squeeze the first post 67 to slide downward.

[0067] A second one-way valve 15 is provided at one end of the regulating chamber 62 , and the second one-way valve 15 is connected to the push column 69 via a cable 16 ;

[0068] The upper end of the second piston cylinder 77 is connected to a transmission tube, and the upper end of the transmission tube is communicated with one end of the second one-way valve 15 .

[0069] The lower ends of the first trapezoidal column 52 and the second trapezoidal column 55 are provided with two inclined surfaces;

[0070] The ram drives the part 12 to slide from right to left, so that the ram drives the part 12 to first contact the first trapezoidal column 52, and squeezes the liquid inside the square frame 51 to one of the regulating chambers 62 through the first trapezoidal column 52. The liquid in the regulating chamber 62 squeezes and opens the first one-way valve 63, thereby allowing the liquid to pass through the first one-way valve 63 and enter the third tube 64. The liquid is transmitted to the first piston cylinder 71 through the third tube 64, thereby pushing the first piston column 72 to slide downward and contact the milling belt 4, thereby changing the shape of the lower end of the milling belt 4. When the first one-way valve 63 is opened, the first one-way valve 63 will drive the pull plate 17 to slide downward, and the pull plate 17 drives the sealing plate 18 to slide downward, so that the sealing plate 18 is sealed at the lower end of another regulating chamber 62. In this way, when the part 12 contacts the second trapezoidal column 55, the second trapezoidal column 55 will squeeze The liquid inside the square frame 51 enters the other regulating chamber 62. Since the sealing plate 18 seals the lower end of the regulating chamber 62, the liquid inside the regulating chamber 62 is squeezed to open the second one-way valve 15, so that the liquid inside the other regulating chamber 62 passes through the second one-way valve 15 and enters the second piston cylinder 77. The second piston column 78 is squeezed by the liquid to slide downward, and the second piston column 78 drives the second telescopic column 79 and the pressing plate 80 to slide downward. The pressing plate 80 is used to further squeeze the airbag 76, so as to improve the rigidity of the airbag 76 and make the airbag 76 better contact with the milling belt 4. In this way, the second trapezoidal column 55 is squeezed by the part 12 to slide and transmit the liquid to push the first piston column 72, and then the second trapezoidal column 55 is squeezed by the part 12 to slide and transmit the liquid to push the pressing plate 80 to contact the airbag 76.

[0071] It should be noted that when the ram drives the part 12 to slide from left to right, the ram drives the part 12 to first abut against the second trapezoidal column 55, causing the first piston column 72 to push the milling belt 4 to deform. When the sliding part 12 abuts against the first trapezoidal column 52 again, the above operation is performed, causing the liquid to enter the second piston cylinder 77. In this way, no matter whether the operator places the part on the left or right side of the milling belt 4, the shape of the lower end of the milling belt 4 can be changed and the airbag 76 can be locked.

[0072] It should be noted that the airbag 76 is woven from a steel mesh, the outer surface of the steel mesh is filled with rubber, and the inside of the airbag 76 is filled with liquid, so that the airbag 76 can be deformed and fit the lower end surface of the milling belt 4. However, since the plasticity of the airbag 76 is too strong, after the first piston column 72 contacts the milling belt 4 and changes its shape, the airbag 76 may deform again, resulting in a large area of ​​the airbag 76 being unable to always contact the milling belt 4. Therefore, when the first piston column 72 contacts the milling belt 4 and changes its shape, the airbag 76 is attached to the milling belt 4, and then the pressing plate 80 is slid so that the pressing plate 80 squeezes the airbag 76, thereby increasing the rigidity of the airbag 76 and preventing the airbag 76 from deforming again. Example

[0073] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-6 The dust collecting device 8 further includes a cylinder 91 mounted inside the connecting frame 3, a push plate 93 is slidably connected to the inside of the cylinder 91, and the push plate 93 and the cylinder 91 are connected by a hose 96. A delivery pipe 19 is also provided inside the cylinder 91, and the lower end of the delivery pipe 19 is connected to the inside of the steel pipe 84;

[0074] A fourth column 94 is mounted on one end of the push plate 93, an inclined plate 95 is mounted on one end of the fourth column 94, and an L-shaped column 88 is mounted on the other end of the push plate 93;

[0075] The dust collecting device 8 includes a slide bar 85 connected to one side of the first piston column 72. One side of the slide bar 85 is rotatably connected to a rotating shaft 87. One side of the rotating shaft 87 is rotatably connected to an extension bar 86. The extension bar 86 and the rotating shaft 87 are connected by a torque spring 89. A limit bar is also installed on one side of the slide bar 85, and one end of the extension bar 86 is used to abut against the limit bar.

[0076] The L-shaped post 88 is used to abut against the protruding bar 86;

[0077] An extrusion column 13 and an extrusion plate 14 are also provided at one end of the bed 1;

[0078] The extrusion column 13 is used to squeeze the inclined plate 95 to slide;

[0079] The extrusion plate 14 is used to squeeze a plurality of push pins 69 to slide;

[0080] The first trapezoidal column 52 is connected to the square frame 51 via a first spring 53 , and the second trapezoidal column 55 is connected to the square frame 51 via a second spring 56 .

[0081] according to Figure 4 and Figure 6 As shown, when several first piston columns 72 near the dust collector head 83 slide downward, the first piston column 72 will drive the slide bar 85 to slide downward, and the slide bar 85 will drive the extension bar 86 to slide downward, so that the extension bar 86 will be separated from the L-shaped column 88. Since the L-shaped column 88 has no limit, the fourth spring 92 pulls the push plate 93, the third column 90 and the L-shaped column 88 to slide to one end, so that the push plate 93 squeezes the liquid inside the cylinder 91 to the delivery pipe 19, and the delivery pipe 19 transmits the liquid to the steel pipe 84. Figure 1 As shown, the third piston column 82 is pushed to slide toward one end by the liquid, thereby changing the position of the dust collecting head 83 so that the dust collecting head 83 can be close to one end of the part 12, thereby improving the dust collecting effect;

[0082] It should be noted that according to Figure 6As shown, the size of each cylinder 91 gradually increases, so the amount of liquid stored inside each cylinder 91 is different, so as to adapt to parts 12 of different sizes;

[0083] When milling is completed, the hydraulic cylinder 2 drives the connecting frame 3 and the milling belt 4 to slide upward and reset, so that the extrusion column 13 will abut against the inclined plate 95, thereby squeezing the protruding inclined plate 95 by the extrusion column 13 to slide, so that the inclined plate 95 pushes the fourth column 94 and the third column 90 to slide, and the third column 90 drives the L-shaped column 88 to abut against the protruding bar 86, and the L-shaped column 88 squeezes the protruding bar 86 to slide to one side, so that the L-shaped column 88 abuts against one side of the protruding bar 86 again, and the protruding bar 86 abuts against the limit bar, thereby facilitating the next milling;

[0084] The push column 69 is squeezed by the extrusion plate 14 to slide toward the inside of the regulating chamber 62, so that the push column 69 squeezes the first column 67 and the second column 68 to slide downward, and the second column 68 squeezes the first one-way valve 63 to open. The first piston column 72 is reset by the contraction of the milling belt 4, so that the liquid inside the first piston cylinder 71 returns to the regulating chamber 62 through the first one-way valve 63, and the liquid in the regulating chamber 62 flows back to 51. When the push column 69 slides, the push column 69 will also pull the second one-way valve 15 to open, so that the liquid in the second piston cylinder 77 also flows back to the regulating chamber 62.
