A roller seat 2 is provided on the supporting seat 1, and a plurality of groups of V-shaped rollers 3 are arranged in parallel on the roller seat 2, and the angle steel 4 is placed on the V-shaped roller 3.

[0033] The adaptive clamping mechanism 5 includes a guide slider 51 arranged at both ends of two groups of bidirectional screw rods 12, and the two sides of the guide slider 51 are respectively screwed with the two groups of bidirectional screw rods 12, and an L-shaped clamp 52 is slidably connected inside the guide slider 51, and a tension spring 53 is connected between the L-shaped clamp 52 and the inner wall of the guide slider 51, and the lateral end of the L-shaped clamp 52 abuts against the end of the angle steel 4, and a limiting component 56 is provided at the bottom of the lateral end of the L-shaped clamp 52, and an adjusting device 54 is provided at the top of the lateral end of the L-shaped clamp 52 for adjusting the position of the limiting component 56 to adapt to the positioning of the angle steel 4. The two groups of support plates 11 are provided with an inclined guide rail 6 away from each other on one side, and the inclined guide rail 6 is slidably connected to the L-shaped clamp 52.

[0034] The root cleaning and milling mechanism 8 includes a connecting plate 81 fixed between two groups of main brackets 7, and a sliding rod 82 and a first screw rod 83 are respectively arranged between the two groups of main brackets 7. A tool holder 84 is slidably connected to the connecting plate 81. The tool holder 84 is screwed to the first screw rod 83 and is slidably connected to the sliding rod 82. A second motor 87 is arranged on the top of the tool holder 84, and the second motor 87 drives the tool assembly to operate.

[0035] The adaptive root milling of the present invention is mainly divided into two steps:

[0036] First, adaptive clamping movement: the adaptive clamping mechanism 5 is in an open state before working. When working, the angle steel 4 is placed on the V-shaped roller 3, and the outer 90° corner of the angle steel 4 fits with the V-shaped roller 3 arranged in parallel. The motor connected to the bidirectional screw rod 12 is started to drive the bidirectional screw rod 12 to rotate, so that the bidirectional screw rod 12 drives the guide sliders 51 on both sides to approach each other along the axial direction of the bidirectional screw rod 12, and the guide sliders 51 on both sides move to drive the corresponding L-shaped clamps 52 to move in the direction of approaching each other. Under the action of the tension spring 53, the two groups of L-shaped clamps 52 move along the inclined direction of the inclined guide rail 6 while approaching each other. When the two groups of L-shaped clamps 5 When the two sets of bidirectional screw rods 12 move to contact the ends of the angle steel 4, they stop running and automatically complete self-locking, thereby realizing the precise clamping of the upper structure of the angle steel 4. The lower structure is fitted with the outer side of the angle steel 4 at 90 degrees through a plurality of V-shaped rollers 3 arranged in parallel, completing the clamping of the lower structure of the angle steel 4, so as to improve the precise positioning of the angle steel 4, and can be adapted to different types of angle steels 4 for use, without the need to manually repeatedly adjust the size of the clamp, thereby reducing the difficulty of the operation of the angle steel 4 and improving the efficiency of the root cleaning of the angle steel 4; the angle steel 4 is milled in a single stroke or multiple strokes by the root cleaning milling mechanism 8, effectively reducing the wear of the tool and ensuring the quality of the root cleaning.

[0037] Reference Figure 6 , taking the 36-type equilateral angle steel 4 as an example, the angle steel 4 side width b = 360mm, the side thickness d = 35mm, the inner arc radius r = 30mm, the specific clamping process is as follows:

[0038] First, place the No. 36 angle steel 4 on the V-shaped roller 3, and the motor drives the bidirectional screw 12 to rotate, thereby driving the two sets of guide sliders 51 to move from the initial position to the direction of approaching each other, and driving the two sets of L-shaped clamps 52 to move toward each other along the inclined guide rail 6. The angle between the inclined guide rail 6 and the vertical direction is set to 47.7°. The bidirectional screw 12 is single-headed and has a pitch of 8mm. Therefore, when the bidirectional screw 12 rotates n times to achieve clamping, the guide slider 51 moves 8n mm from the initial position to the direction of approaching each other, thereby driving the two sets of L-shaped clamps 52 to move 8n mm to the direction of approaching each other. In the triangle NPO, , mm, L-type fixture 52 moves downward in the vertical direction mm, at this time, the two sets of L-shaped clamps 52 are in contact with the angle steel 4 and self-locked to complete the clamping; at this time, the angle steel 4 is placed on the V-shaped roller 3, and the V-shaped edge of the angle steel 4 is placed at 45° to the horizontal plane. According to the calculation, the distance of the angle steel 4 in the vertical direction of the ground at this time is , bring in the 36# angle steel 4, according to the calculation H=254.56mm, the height that the L-shaped clamp 52 needs to drop is h=270-254.56=15.44mm, the angle of the L-shaped clamp 52 is 47.7°, PO=15.44mm, then Therefore, the number of turns of the bidirectional screw 12 is n=14.05 / 8=1.75625 turns. Therefore, when the bidirectional screw rotates 1.75625 turns clockwise, the No. 36 angle steel 4 is clamped.

[0039] Second, root cleaning and milling movement: when the L-shaped clamp 52 clamps the upper end structure of the angle steel 4, the tool assembly is not started at this time and remains in a position away from the root cleaning part of the angle steel 4; the main bracket 7 is driven to move, and the root cleaning and milling mechanism 8 is driven to move to the specified position to prepare for subsequent root cleaning and milling, and the first screw rod 83 is started. The first screw rod 83 drives the tool holder 84 to move to the left along the slide rod 82 and the connecting plate 81 until it moves to the leftmost position, ensuring that the tool assembly is in the correct starting position, and starting the tool assembly to start the milling operation; during the milling process, the tool assembly completes multiple root cleaning and milling of the angle steel 4 through forward milling and reverse milling to ensure the milling accuracy and the quality of the angle steel 4 processing.

[0040] After the root cleaning and milling operation is completed, the motor reverses and drives the bidirectional screw 12 to rotate in the opposite direction, driving the two groups of guide sliders 51 to move away from each other, and the two groups of guide sliders 51 drive the two groups of L-shaped clamps 52 to move away from the angle steel 4, and disengage from the constraints between the L-shaped clamps 52 and the angle steel 4, and complete self-locking through the bidirectional screw 12. Multiple groups of parallel V-shaped rollers 3 are connected by belts, and the motor is started to drive the belt to rotate, so that the V-shaped rollers 3 rotate, and the angle steel 4 is driven to be discharged from the discharge port by friction, thereby completing the root cleaning and milling operation of the angle steel 4 and ensuring the quality of the angle steel 4.

[0041] See attached Figure 2-3 As a possible implementation of the present solution, preferably, a positioning groove 55 is provided on the lateral end of the L-shaped clamp 52 , and the limiting component 56 is slidably arranged along the positioning groove 55 .

[0042] The vertical section of the L-shaped clamp 52 is provided with an inclined slide groove 521, and the inclined slide groove 521 is slidably connected to the inclined guide rail 6. A pulley 522 is installed on the top of the inclined slide groove 521 through a connecting frame 523. The top of the inclined guide rail 6 is provided with an inclined connecting groove 61, and the pulley 522 is slidably connected to the inclined connecting groove 61.

[0043] The bidirectional screw rod 12 rotates to drive the L-shaped clamp 52 to move. When the L-shaped clamps 52 approach each other, the inclined slide groove 521 is slidably connected with the inclined guide rail 6. At the same time, under the action of the tension spring 53, the pulley 522 is driven to slide along the inclined connection groove 61 all the time, so that the L-shaped clamps 52 approach each other and slide downward along the inclined guide rail 6 to adapt to different types of angle steels 4. There is no need to manually adjust the clamping position of the clamp, which reduces the difficulty of operating the angle steel 4 and improves the operating efficiency.

[0044] Example 2

[0045] See attached Figure 3-4 As a possible implementation mode of the present scheme, preferably, the adjusting device 54 includes fixed seats 541 arranged on both sides of the top of the lateral end of the L-shaped clamp 52, and a screw 542 is rotatably connected between the two groups of the fixed seats 541. A movable support 543 is screwed on the screw 542, and the movable support 543 is slidably connected to the positioning slide groove 55. One end of the screw 542 is connected to a first motor 544, and the limiting assembly 56 is fixed to the side of the movable support 543 close to the angle steel 4.

[0046] The limiting assembly 56 includes a mounting seat 562 fixed on one side of the movable support 543, a clamping plate 563 rotatably connected inside the mounting seat 562, the clamping plate 563 is clamped on the bottom of the end of the angle steel 4, and a protruding end 561 for limiting the rotation of the clamping plate 563 is provided on the side of the mounting seat 562 close to the angle steel 4, and a limiting spring 564 is connected between the side of the clamping plate 563 away from the angle steel 4 and the movable support 543.

[0047] When it is necessary to adapt the position according to the model of the angle steel 4, the L-shaped clamp 52 moves to contact the end of the angle steel 4 under the action of the bidirectional screw rod 12, and the first motor 544 is started. The first motor 544 drives the screw rod 542 to rotate, thereby driving the movable support 543 to move, and the movable support 543 drives the mounting seat 562 to move, so that the mounting seat 562 drives the clamping plate 563 to adjust to abut against the outer side surface of the upper end of the angle steel 4, so that the two groups of clamping plates 563 clamp the angle steel 4 from both sides, further improving the precise positioning of the angle steel 4, ensuring the accuracy of subsequent root cleaning and milling, so as to improve the quality of the angle steel 4 operation, and under the action of the limit spring 564, the clamping plate 563 can be tightly attached to the angle steel 4 and adapted to it.

[0048] Example 3

[0049] See attached Figure 5 As a possible implementation of the present scheme, preferably, the tool assembly includes a second screw rod 85 arranged on the tool holder 84, and a tool seat 86 is screwed on the second screw rod 85. Guide rods 861 are arranged on both sides of the tool holder 84. The guide rods 861 are slidably connected to the tool seat 86. A milling cutter disc 9 is installed at the bottom of the tool seat 86, and a second motor 87 is installed on the tool seat 86. The driving end of the second motor 87 drives the milling cutter disc 9 to rotate through a conveyor belt 88.

[0050] A guide end 13 is provided at the bottom of one side where the two groups of main brackets 7 are close to each other, and the guide end 13 is slidably connected to the connecting rods on both sides of the support seat 1.

[0051] During the root cleaning and milling operation, the first screw rod 83 and the cooperation between the main bracket 7 and the guide end 13 move the milling cutter disc 9 to the leftmost position, so that the milling cutter disc 9 is located at the correct starting position, the second motor 87 is started, and the milling cutter disc 9 is driven to rotate through the conveyor belt 88, so that the milling cutter disc 9 starts to work, and the second screw rod 85 is driven to rotate by the second motor 87 to drive the cutter seat 86 and the milling cutter disc 9 installed on the cutter seat 86 to move downward, and contact the root cleaning part of the angle steel 4 to start the milling operation;

[0052] During the milling process, the main bracket 7 is used to control the milling cutter disc 9 to perform forward milling from front to back until one end of the angle steel 4 is processed. The movement of the main bracket 7 can be controlled by a mechanism that performs linear repetitive motion, such as a screw rod assembly, a cylinder or an electric push rod. Then the second motor 87 drives the first screw rod 83 to rotate, so that the tool holder 84 drives the milling cutter disc 9 to move to the right along the slide rod 82 and adjust it to the set root cleaning width to ensure that the milling cutter disc 9 covers the entire root cleaning area. At the same time, the second motor 87 controls the second screw rod 85 to rotate, so that the milling cutter disc 9 moves downward to the set root cleaning depth, and then controls the main bracket 7 to move in the opposite direction, driving the milling cutter disc 9 to perform reverse milling from back to front, completing multiple root cleaning milling of the angle steel 4 to ensure the milling accuracy and the price quality of the angle steel 4.
