[0030] The present invention will be further described below by way of embodiments in conjunction with the accompanying drawings.

[0031] refer to Figures 1 to 6 A guide rail processing device includes a material rack 2, a finished material rack 3, and a processing table 4 which are arranged in sequence. The material rack 2 is composed of a plurality of loading tables, and each loading table is spaced apart in the horizontal direction. The material rack 2 and the finished material rack 3 are both used to place the guide rail workpiece 1 horizontally. The processing table 4 is provided with a traveling frame 7. The top of the traveling frame 7 includes two symmetrically arranged longitudinal beams 701 and a cross beam 702 slidably arranged between the two longitudinal beams 701. The cross beam 702 is slidably provided with at least two lifting and transporting mechanisms 8. The cross beam 702 is provided with a first traveling mechanism 9 which drives it to translate along the length direction of the longitudinal beam 701, so that the lifting and transporting mechanism 8 can move back and forth between the material rack 2, the finished material rack 3, and the processing table 4.

[0032] The lifting transport mechanism 8 includes a mounting seat 81, two first lifting mechanisms 82 arranged in parallel and spaced apart on the mounting seat 81, and a support member 83 arranged on the lifting end of the first lifting mechanism 82. An escape space for the placement table 5 to pass through is formed between the two first lifting mechanisms 82 on the mounting seat 81. The support member 83 is C-shaped and its opening faces the side close to the material rack 2. The inner wall of the opening of the support member 83 has an outwardly convex limiting protrusion 801. The limiting protrusion 801 cooperates with the ridge 102 of the guide rail workpiece 1 to support the guide rail workpiece 1 so that it can be placed horizontally and moved longitudinally by the first walking mechanism 9. The positions of the two lifting and transporting mechanisms 8 on the upper adjusting beam 702 are lifted and translated by the support member 83 driven by the first lifting mechanism 82, so as to transport the guide rail workpiece 1 laterally to the material rack 2 or the finished product material rack 3 or the processing table 4. There is no need to manually transport the guide rail workpiece 1, thus avoiding the problems of misoperation and low efficiency. In addition, the lifting and transporting mechanism 8 adopts two support members 83 with an open design, and the opening of the support member 83 faces the side close to the material rack 2 for the guide rail workpiece 1 to be placed laterally, thus avoiding damage and deformation caused by pressure on the guide wall 101 of the guide rail workpiece 1.

[0033] The mounting seat 81 is provided with a second traveling mechanism 10 for driving it to translate along the length direction of the cross beam 702 , so as to adjust the distance between the two lifting and transporting mechanisms 8 according to the length of the guide rail workpiece 1 , thereby improving the applicability of the lifting and transporting mechanism 8 .

[0034] The processing table 4 is provided with two parallel and spaced-apart transverse slide rails 6, and a placement table 5 located between the two transverse slide rails 6.

The vertical translation mechanism 112 is a telescopic cylinder or an electric push rod. The translation end of the vertical translation mechanism 112 is provided with an L-shaped clamping member 12, and a movable hole 502 is passed through the placement table 5 for the clamping member 12 to translate vertically.

[0036] The longitudinal translation mechanism 113 is a telescopic cylinder or an electric push rod, and a pressure plate 13 is provided at the translation end of the longitudinal translation mechanism 113. A movable groove 1301 passes through the middle of the pressure plate 13, and the side of the support seat 111 extends into the movable groove 1301 and the two are pivotally matched, so that the pressure plate 13 can be flipped and movably arranged on the side of the support seat 111. The upper part of the pressure plate 13 is pivotally matched with the translation end of the longitudinal translation mechanism 113, and the lower part of the pressure plate 13 is provided with a buffer pad 1302 adapted to the guide rail workpiece 1. When the longitudinal translation mechanism 113 extends outward in translation, the lower part of the pressure plate rotates inward so that a clamping space for clamping the guide rail workpiece 1 is formed between the buffer pad 1302 and the opposite side of the placement table 5.

[0037] When the guide rail workpiece 1 is placed horizontally on the side wall of the placement table 5, one end of each clamping member 12 extends out of the movable hole 502 and cooperates with each other for the guide rail workpiece 1 to be placed horizontally, and the vertical translation mechanism 112 drives the corresponding clamping member 12 to translate upward, and one end of the clamping member 12 passes through the movable hole 502 and cooperates with the top of the placement table 5 to vertically clamp the horizontally placed guide rail workpiece 1, so that the guide wall 101 of the guide rail workpiece 1 corresponds to the corresponding processing reserved hole 501, and then, the longitudinal translation mechanism 113 drives the pressure plate member 13, and the lower part of the pressure plate member 13 cooperates with the side wall of the placement table 5 to clamp the horizontally placed guide rail workpiece 1 in the longitudinal direction, thereby limiting the guide rail workpiece 1 to cooperate with the side wall of the placement table 5, avoiding interference with the lifting and transporting mechanism 8 when it is separated from the guide rail workpiece 1, ensuring the stable positioning of the guide rail workpiece 1 during the drilling process, and improving the processing accuracy.

[0038] Two drilling devices 14 are slidably arranged in parallel and at intervals on the transverse slide rail 6. The drilling devices 14 on the two transverse slide rails 6 are arranged opposite to each other. The drilling devices 14 are provided with a third traveling mechanism 15 for driving them to translate along the length direction of the transverse slide rail 6. The position of the drilling device 14 is adjusted in the transverse direction by the third traveling mechanism 15, so that the drilling device 14 is provided with a processing end that drives the drilling device 14 to correspond to the processing reserved hole 501.

[0039] Preferably, the first traveling mechanism 9, the second traveling mechanism 10 and the third traveling mechanism 15 are all gear rack transmission devices, which are composed of gears and racks. The rack can be set on a slide rail for guiding linear motion. When the gear rotates, the rack is fixed, and the rotational motion of the gear is converted into linear motion of the rack through meshing. The gear rack transmission has a high transmission efficiency, can ensure the constancy of the instantaneous transmission ratio, has good transmission stability, and transmits motion accurately and reliably.

[0040] The drilling device 14 includes a first mounting plate 141, a push-translation mechanism 142, a second mounting plate 143, and a drilling machine 144. The first mounting plate 141 is slidably connected to the transverse slide rail 6, the second mounting plate 143 is slidably connected to the first mounting plate 141, the push-translation mechanism 142 is a telescopic cylinder or an electric push rod, the push-translation mechanism 142 is arranged on the first mounting plate 141, and the translation end of the push-translation mechanism 142 is connected to the second mounting plate 143, and the drilling machine 144 is fixedly connected to the second mounting plate 143, and the push-translation mechanism 142 drives the drilling machine 144 to approach or move away from the placement table 5. The guide rail workpiece 1 placed horizontally on the placement table 5 is drilled. After the drilling of the guide rail workpiece 1 on the placement table 5 is completed, one of the first lifting mechanisms 82 on the mounting seat 81 drives the corresponding support member 83 to take out the drilled guide rail workpiece 1. Thereafter, by adjusting the longitudinal position of the crossbeam 702, the other first lifting mechanism 82 on the mounting seat 81 drives the corresponding support member 83 to place the guide rail workpiece 1 to be drilled horizontally on the side wall of the placement table 5, thereby realizing continuous processing of the guide rail workpiece 1, effectively improving work efficiency, and ensuring the processing accuracy and service life of the guide rail workpiece 1.

[0041] Preferably, the drilling machine 144 is provided with a nozzle 16, and the water spraying direction of the nozzle 16 is toward the drill bit of the drilling machine 144, so as to flush the cuttings generated by the drilling away from the guide rail workpiece 1. A transversely extending chip removal channel 17 is provided on the top surface of the processing table 4 relative to the position between the placing table 5 and the transverse slide rail 6, and the top of the chip removal channel 17 is opened. A guide portion 503 is provided on the side wall of the placing table 5 close to the drilling device 14, and the outer surface of the guide portion 503 is inclined toward the opening of the chip removal channel 17. Under the guidance of the guide portion 503, the flushed chips flow to the opening in the chip removal channel 17 with the liquid, so as to collect the chips. A chip removal device 18 connected to the chip removal channel 17 is provided on one side of the processing table 4, and a recovery pipe 19 connected to the chip removal channel 17 is provided on the other side of the processing table 4.

[0042] Preferably, the inner wall of the opening of the chip channel 17 is provided with a plurality of partitions 1701 spaced apart along the length direction of the chip channel 17. The partitions 1701 can divide the opening area of ​​the chip channel 17 into a plurality of smaller channels, guiding the chips to flow along a specific direction and path, allowing the chips to enter the chip channel 17 more orderly, avoiding the chips from accumulating at the opening or scattering everywhere, thereby improving the efficiency and smoothness of chip removal. The partitions 1701 can also play a blocking role, reducing the possibility of chip backflow, ensuring that the chips flow unidirectionally along the direction of the chip channel 17 under the action of the chip removal device 18, thereby ensuring the stability of chip removal.

[0043] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
