[0081] A method for drilling teeth on a rail is as follows:

[0082] S1: Place the rail on the support mechanism 3, adjust the height of the rail through the positioning plate assembly, and position the rail through the stop block assembly;

[0083] S2: Start the hydraulic cylinder 501 to extend and tighten the rail through the pressing plate assembly;

[0084] S3: Adjust the distance between the two power assemblies by adjusting the pull rod 602. The control system controls the double-spindle power head mechanism 6 to move along the Y-axis electric rail 107, and drill the two ears of the rail synchronously through the two power assemblies;

[0085] S4: When drilling the teeth on a rail on one workbench mechanism 2, perform the loading and unloading operation of the rail on the other workbench mechanism 2.

[0086] The working principle of the present invention is as follows:

[0087] The original method of drilling holes in the two ears of the tooth rail one by one is changed to drilling holes simultaneously by two power components with built-in high-pressure water pumps on the bottom plate 601, which saves the drilling time of the tooth rail, improves the efficiency, solves the problem of low drilling efficiency of the tooth rail, can complete the tooth rail drilling process in a short time, and improves the production efficiency;

[0088] The two ears of the tooth rail are drilled synchronously by two power components. During the drilling process, the tooth rail is more evenly stressed, reducing the possibility of displacement and improving the drilling quality;

[0089] The original single-piece clamping is changed to double-station clamping through the hydraulic fixture tooling components installed on the two workbench mechanisms 2. While drilling, another workpiece can be clamped, saving the clamping time of the tooth rail, improving the efficiency, solving the problems of low clamping efficiency of the tooth rail and high labor intensity of employees, and further improving the production efficiency;

[0090] The tooth rail is lapped on the two support mechanisms 3. The height of the positioning plate 306 can be adjusted through the hydraulic rod 307, so as to adjust the drilling height of the tooth rail. After finding the position of the tooth rail through the adjustment of the support mechanism 3, start the hydraulic cylinder 501 to make the pressure plate assembly pass through the gap of the tooth rail. Twist the knob 509 to make the positioning rod 512 move out of the slot 507 and latch into another slot 507, so as to screw out the induction strip 511 from the inner slot 506. Contract the hydraulic cylinder 501 to make the induction strip 511 move down and detect whether the tooth rail is horizontal through the sensor. According to the feedback result of the sensor, the height adjustment of the positioning plate assembly can be adjusted in real time, so as to improve the drilling accuracy.

[0091] After the leveling work of the tooth rail is completed, rotate the knob 509 to make the induction strip 511 return to its original position. Then, turn out the pressing block 504 with the block shaft 503 as the axis to expand the radius range covered by the pressing plate 502. Contract the hydraulic cylinder 501 to make the pressing block 504 press on the tooth rail to tighten and fix the tooth rail. In the non-working state, the pressing block 504 can be retracted into the pressing plate 502 without affecting the passage of the pressing plate assembly through the gap of the tooth rail, and there is no need to install the pressing plate assembly subsequently, improving the use convenience.

[0092] After the tooth rail is placed on the support mechanism 3, screw out the support rod 406 and pull the connecting arm 404 outwards along the slide rail 402 to pull it out of the first card slot 304. Under the action of the torsion spring shaft 403, the back plate 407 and the backing plate 408 automatically turn over to fit the tooth rail. Screw the support rod 406 into the pressing plate 502 again according to the fitting position to abut against the connecting arm 404. When the power component drills the tooth rail, the back plate 407 and the backing plate 408 can support the tooth rail, evenly stress the tooth rail workpiece, and improve the protection of the workpiece.

[0093] Through the setting of the stabilizing components on both sides of the water-out U-drill 606, it is possible to fit the tooth rail before the water-out U-drill 606 contacts the tooth rail and push the tooth rail. On the one hand, before drilling, it is possible to visually see whether the position of the drill hole is accurate from the position between the stabilizing components on both sides. On the other hand, the stabilizing components cooperate with the back support mechanism 4 to support the tooth rail synchronously from the front and back sides of the tooth rail, further improving the stability of tooth rail drilling.

[0094] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
