[0103] Working principle:
[0104] The cylinder bodies of the second cylinder 12 and the third cylinder 15 are fixedly connected to the mounting block 1, and the piston rods of the second cylinder 12 and the third cylinder 15 are fixedly connected to the first guide rail positioning block 13 and the first processing table positioning block 16, respectively. It should be noted that the top and bottom surfaces of the guide rail 9 are parallel, the two side surfaces are parallel to each other, and the side surfaces are perpendicular to the top surface. The first motor 51 and the second motor 56 are brake motors; when they stop working, their output shafts will be braked and locked.
[0105] First, the output shaft of the first motor 51 of the conveying device rotates. The first motor 51 drives the first rotating shaft 52 to rotate via a reducer, which in turn drives the first gears 53 on both sides to rotate. The first gears 53 mesh with the first rack 42, driving the first moving plate 5 to move along the second guide rail 41 to above the guide rail placement platform 91 on which the guide rail 9 is placed. The first motor 51 stops working, and the second motor 56 drives the second rotating shaft 57 to rotate via a reducer, which in turn drives the second gears 58 on both sides to rotate. The second gears 58 mesh with the second rack 552, driving the two moving columns 55 to descend synchronously.
[0106] When the guide rail 9 is positioned between the two grippers of the gripper cylinder 28, the second motor 56 stops working and brakes, and the two grippers of the gripper cylinder 28 clamp and fix the guide rail 9. Then, the second motor 56 drives the moving column 55 and the moving frame 3 to move upward a certain distance. Next, the first motor 51 drives the gripper cylinder 28 and the gripped guide rail 9 to move along the second guide rail 41 above the processing table 81 of the processing device 8.
[0107] Then the first motor 51 stops working, the piston rods of the fifth cylinders 24 on both sides extend, driving the support blocks 25 on both sides to move downward. The mounting plate 2 moves downward with the support blocks 25, and the first positioning block 26 disengages from contact with the second positioning block 27.
[0108] Then, the second motor 56 drives the moving frame 3 and the mounting plate 2 to move downwards. When the bottom surface of the guide rail 9 contacts and abuts the positioning top surface 811 of the machining table 81, the second motor 56 stops moving. Then, the two grippers of the gripper cylinder 28 release the guide rail 9. At this time, the first machining table positioning block 16 and the second machining table positioning block 17 are located on the left and right sides of the machining table 81, respectively, and the first guide rail positioning block 13 and the second guide rail positioning block 14 are located on the left and right sides of the guide rail 9, respectively. At this time, the moving frame 3 remains stationary relative to the machining table 81.
[0109] Since the plane containing the positioning surfaces of all the second machining table positioning blocks 17 may not be perfectly parallel to the positioning side 812, if the mounting plate 2 and the second machining table positioning blocks 17 can only move vertically relative to the machining table 81 during positioning, the positioning surface of the second machining table positioning block 17 will maintain an error angle with the positioning side 812 after contacting it. Since the positioning surface of the second guide rail positioning block 14 is parallel to the positioning surface of the second machining table positioning block 17, the positioning surface of the second guide rail positioning block 14 also has an error angle with the positioning side 812. Under the drive of the second cylinder 12, the side of the guide rail 9 will fit against the positioning surface of the second guide rail positioning block 14, resulting in an error angle between the side of the guide rail 9 and the side of the machining table 81, causing inaccurate positioning of the guide rail 9 and resulting in errors in the subsequent processing of the machining device 8.
[0110] To overcome the above-mentioned shortcomings, the movable frame 22 can rotate and translate relative to the movable frame 3 during positioning. The support block 25 includes a cylindrical part and an enlarged part, which are integrally formed. The cylindrical part is located in the U-shaped groove 231, and the U-shaped groove 231 can move relative to the cylindrical part in the left-right and front-back directions. Preferably, the U-shaped groove 231 can be replaced by a through hole with a diameter larger than that of the cylindrical part.
[0111] The piston rod of the third cylinder 15 extends, driving the first machining table positioning block 16 to move closer to the second machining table positioning block 17, until all the first machining table positioning blocks 16 and all the second machining table positioning blocks 17 contact the two positioning sides 812 of the machining table 81 respectively. During this process, the movable frame 22 moves slightly relative to the moving frame 3 (the U-shaped groove 231 moves relative to the support block 25), thereby ensuring that the positioning surfaces of all the second machining table positioning blocks 17 are in contact with the positioning sides 812. At this time, the relative positions of the second guide rail positioning block 14 and the second machining table positioning block 17 are stationary relative to the machining table 81.
[0112] Then, the piston rod of the second cylinder 12 extends, driving the first guide rail positioning block 13 to move closer to the second guide rail positioning block 14. After the first guide rail positioning block 13 contacts the side of the guide rail 9, it drives the guide rail 9 to move closer to the second guide rail positioning block 14 until both sides of the guide rail 9 contact all the first guide rail positioning blocks 13 and all the second guide rail positioning blocks 14 respectively.
[0113] It should be noted that the positioning surfaces of the first guide rail positioning block 13, the second guide rail positioning block 14, the first machining table positioning block 16, and the second machining table positioning block 17 are parallel. All positioning surfaces of the first guide rail positioning blocks 13, all positioning surfaces of the second guide rail positioning blocks 14, all positioning surfaces of the first machining table positioning blocks 16, and all positioning surfaces of the second machining table positioning blocks 17 are located on the same plane. Here, the positioning surface of each of the aforementioned positioning blocks refers to the surface that contacts the side of the guide rail 9 or the positioning side 812.
[0114] Since the positioning surfaces of multiple first guide rail positioning blocks 13 are in contact with the side of the guide rail 9, and the positioning surfaces of multiple second guide rail positioning blocks 14 are in contact with the other side of the guide rail 9, the multi-point positioning guide rail 9 will not be tilted relative to the processing table 81, that is, the two sides of the guide rail 9 are parallel to the two positioning sides 812 of the processing table 81.
[0115] After positioning is completed, electromagnet 82 fixes the iron-containing guide rail 9 and processing table 81 with magnetic force. Then, the piston rods of the second cylinder 12 and the third cylinder 15 retract, driving the first guide rail positioning block 13 and the first processing table positioning block 16 to move away from the second guide rail positioning block 14 and the second processing table positioning block 17, respectively, until a sufficiently large gap is formed between the first guide rail positioning block 13 and the side of its corresponding guide rail 9, and a sufficiently large gap is formed between the first processing table positioning block 16 and its corresponding positioning side 812.
[0116] Subsequently, the piston rod of the fourth cylinder 18 extends, driving the first guide rail 11 to slide along the first slider 21. The second guide rail positioning block 14 and the second machining table positioning block 17 move synchronously with the first guide rail 11. The second guide rail positioning block 14 and the second machining table positioning block 17 move away from the guide rail 9 until they disengage from the guide rail 9 and the machining table 81, respectively. At this point, the sides of the guide rail 9 are not in contact with the first guide rail positioning block 13 and the second guide rail positioning block 14, and neither the first machining table positioning block 16 nor the second machining table positioning block 17 is in contact with the positioning side 812.
[0117] The second motor 56 drives the mounting plate 2 and the moving frame 3 to rise, so that the first processing table positioning block 16 and the second processing table positioning block 17 are higher than the guide rail 9 by a certain height, so that the position of the positioning device does not interfere with the operation of the processing device 8.
[0118] Next, the processing device 8 processes the guide rail 9 on the processing table 81. After the processing device 8 completes the processing of the guide rail 9, the second motor 56 drives the mounting plate 2 and the moving frame 3 to descend, so that the guide rail 9 is located between the two jaws of the gripper cylinder 28. After the two jaws of the gripper cylinder 28 clamp and fix the processed guide rail 9, the second motor 56 drives the mounting plate 2 and the moving frame 3 to rise to the specified height.
[0119] Subsequently, the piston rod of the fifth cylinder 24 retracts, causing the support block 25 to move upward. The movable frame 22 and the first fixed plate 23 move upward with the support block 25 until the first positioning block 26 is inserted into the positioning hole 272, so that the positioning column surface 262 fits against the inner wall of the positioning hole 272, and the lower positioning plate 261 and the second positioning plate 271 come into contact, thereby fixing the movable frame 22 and the movable frame 3 and preventing the movable frame 22 and the movable frame 3 from shaking during subsequent horizontal movements.
[0120] Subsequently, the first motor 51 drives the gripper cylinder 28 and the guide rail 9 to be positioned above the guide rail placement table 91 (or other placement table). After the second motor 56 drives the guide rail 9 to contact the guide rail placement table 91, the gripper cylinder 28 releases the processed guide rail 9, completing the grinding and transport operation of one guide rail 9. Afterward, the positioning device picks up the unprocessed guide rail 9, and the above process is repeated.
[0121] While the conveying device transports the processed guide rail 9, the cleaning device cleans the processing table 81. The driving device is an existing device such as a long cylinder, lead screw and nut mechanism, chain, belt, and trolley track. The initial position of the mounting bracket 6 is as follows... Figure 21 As shown, the mounting bracket 6 is located at the front end of the processing table 81 of the processing device 8. The first cylinder 65 drives the second moving plate 66 and the scraper 67 to move upward, so that the scraper 67 does not contact the processing table 81 during its subsequent rightward movement. The driving device drives the mounting bracket 6 to move backward to the rear end of the processing table 81, during which the cleaning device does not contact the processing table 81 at all. Preferably, the processing device 8 is a grinding machine.
[0122] Then, the first cylinder 65 drives the second moving plate 66 and the scraper 67 to move downwards, so that the scraper 67 can contact the positioning top surface 811 and the positioning side surface 812 of the processing table 81, respectively. After that, the drive device drives the mounting bracket 6 to move from the rear to the front of the processing table 81, and the first top surface nozzle 71, the second top surface nozzle 72, and the side nozzles 73 blow compressed gas onto the processing table 81. The scraper 67 first scrapes the larger dirt particles away from the positioning top surface 811 and the positioning side surface 812, and then the first top surface nozzle 71 and the second top surface nozzle 72 blow the smaller dirt particles on the positioning top surface 811 away from the processing table 81, and the two second top surface nozzles 72 on both sides blow the smaller dirt particles on the two positioning side surfaces 812 away from the processing table 81.
[0123] After the mounting bracket 6 moves to the front end of the processing table 81, the scraper 67, the first top surface nozzle 71, the second top surface nozzle 72 and the side nozzle 73 complete the cleaning operation on the top surface 811 and the side surface 812.
[0124] The first clamping block 621 and the second clamping block 631 can adjust the clamping pressure (by rotating the screw or bolt) and fix the rod by friction. When the first clamping block 621 and the second clamping block 631 release the rod, the rod can slide and rotate relative to the first clamping block 621 and the second clamping block 631 to adjust the relative position.
[0125] The first vertical rod 62 is vertically adjustable relative to the first clamping block 621, and the mounting bracket 6 is adjustable relative to the first clamping block 621 in the front-to-back direction, thereby changing the height of the first top surface nozzle 71 and the second top surface nozzle 72, as well as their distance from the scraper 67. The second vertical rod 63 is vertically adjustable relative to the second clamping block 631, and the second vertical rod 63 can rotate relative to the second clamping block 631, thereby changing the height and angle of the side nozzle 73. The second clamping block 631 is horizontally adjustable relative to the transverse rod 64, thereby changing the distance between the side nozzle 73 and the positioning side 812.
[0126] The horizontal bar 64 and the first vertical bar 62 are fixed with clamps having the same structure as the first clamp 621.
[0127] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
