[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described 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.

[0022] like Figures 1 to 5The finished guide rail production line shown in the figure includes a transport component 1, a precision saw processing station 2, a jumper hole processing station 4, a three-head drill group processing station 3, and a spray processing station 5 arranged in sequence along the transport direction of the transport component 1; the precision saw processing station 2 is used to cut the raw material of the rail and transfer the cut rail to the transport component 1; the three-head drill group processing station 3 is used to drill the rail joint hole; the jumper hole processing station 4 is used to drill the jumper hole of the rail; the spray processing station 5 includes a temperature measuring component and a heating component 52 arranged in sequence in the transport direction , painting assembly, the temperature measuring assembly is used to measure the temperature of the rail before it enters the heating assembly 52 and after the heating process, the heating assembly 52 is used to preheat the rail, the shot blasting assembly is used to treat the surface of the rail, the painting assembly is used to spray water-based paint on the surface of the rail and dry it to complete the paint film shaping of the rail; the precision saw processing position 2 cuts the rail raw material on the transport assembly 1 according to the drawing length, the photoelectric gate 27 identifies the position of the rail end and controls the mechanical gripper to clamp the rail to the longitudinal zero position, and after completion, according to the operator's input The length of the material is determined by the mechanical gripper, which drives the rail to move. The length of the mechanical gripper's single movement is 15m. The length control is carried out by the magnetic scale in conjunction with the PLC unit reading and control. If the rail is to be cut longer than 15m, the gripper needs to move back and forth repeatedly to clamp and pull the rail raw material to the cutting length before sawing. After the rail is sawed with precision, the verticality error of the end face in the length direction of the rail is controlled within 0.5mm, which improves the rail processing accuracy. The three-head drill group station is based on the three types of rails (43kg / m, 50kg / m, 6 0kg / m) selects the corresponding three-head drill to complete the drilling of the rail joint hole. When the guide rail needs to be drilled with a jumper hole for track circuit layout, the jumper hole is drilled at the jumper hole processing position 4. After passing through the rail temperature measurement assembly, the heating assembly 52 adjusts the heating power according to the rail surface temperature, so that the heated rail surface temperature reaches the rail process requirement of 35-40°. After that, it flows into the shot blasting assembly. The shot blasted rail flows into the painting assembly to complete the entire process. 5 minutes after the painting is completed, the paint film is set and ready for shipment. Improving the level of automation in the rail processing process avoids the influence of most manual operations on the guide rail machining quality, and improves rail processing production efficiency.

The precision sawing machine 21 is used to measure the photoelectric gate 27 of the rail position; the photoelectric gate 27 is used to detect whether the rail has entered the precision sawing machine 21, and the mechanical gripper clamps the rail for transportation. The transportation length of the mechanical gripper is read and controlled by the magnetic scale in conjunction with the PLC unit. The length of the mechanical gripper's single travel is set to 15m. If it is necessary to cut a rail longer than 15m, the gripper needs to move back and forth and repeatedly clamp and pull the rail raw material to the cutting length. After that, the first clamping part 22 and the second clamping part 23 clamp the rail, and the precision saw 25 cuts the rail.

[0025] Specifically, such as Figure 3 As shown, the temperature measuring component includes a first temperature measuring probe 511 and a second temperature measuring probe 512, the heating component 52 includes a medium frequency heating furnace, the transport component 1 passes through the medium frequency heating furnace, the first temperature measuring probe 511 is set at the input end of the medium frequency heating furnace, and the second temperature measuring probe 512 is set at the output end of the medium frequency heating furnace; the first temperature measuring probe 511 is used to measure the surface temperature of the rail before it enters the medium frequency heating furnace, and the second temperature measuring probe 512 is used to detect the surface temperature of the rail after heating. The medium frequency heating furnace will adjust its own power according to the surface temperature of the rail detected by the second temperature measuring probe 512 so that the temperature of the rail out of the furnace can reach the process requirement of 35-40°C, thereby completing the preheating of the rail; the preheated rail workpiece avoids the problem of frosting and peeling of water-based paint caused by the low temperature of the rail in winter and reaches the optimal operating temperature of the special quick-drying water-based paint, and the preheated rail reduces surface contamination during the paint setting period.
