[0002] With the rapid development of rail transportation, the demand for manufacturing high-speed rail vehicles is increasing. In the production process of high-speed rail vehicles, traction beams are key components, and their processing quality and precision directly affect the performance and safety of the vehicles.

[0003] The fixture's primary function is to assist the CNC vertical machining center in machining the traction beam. Its operating principle is to utilize blank positioning technology to precisely determine the center and angular position of the workpiece and clamp it, ensuring a product that meets standards. In contrast, traditional fixtures cannot directly utilize the blank for positioning, necessitating tedious additional steps such as marking, rough machining, and datum setting on the machined casting. This undoubtedly increases the complexity and cost of the machining process.

[0025] like Figure 1 As shown, the rear end clamping mechanism 2 includes a screw rod A21, which is fixedly connected to the base plate 1, and a pressure plate A22 is sleeved on the outer surface of the screw rod A21. A nut A23 is threadedly installed on the outer surface of the screw rod A21. The nut A23 is used to press the pressure plate A22 toward the fast rail traction beam, so that the pressure plate A22 applies a vertical force to the rear end of the fast rail traction beam, thereby clamping and positioning it.

[0026] like Figure 1 As shown, the side positioning mechanism 3 includes two fixed blocks 31, which are fixedly connected to the base plate 1, and the two fixed blocks 31 are respectively located on the left and right sides of the pressure plate A22. The upper surface of the fixed block 31 is fixedly installed with a screw B32, and the outer surface of the screw B32 is sleeved with a side tightening washer 33, and the outer surface of the screw B32 is threadedly installed with a nut B34. After tightening, the nut B34 is used to tighten the corresponding side tightening washer 33. The two side tightening washers 33 are mainly used to assist in positioning the left and right sides of the rear end of the fast rail traction beam to prevent it from moving to the left and right.

[0027] like Figure 1 As shown, the front-end Y-axis clamping mechanism 5 includes a Y-axis positioning rod 51 and a vertical block A52. The Y-axis positioning rod 51 and the vertical block A52 are fixedly connected to the base plate 1, and the vertical block A52 is located behind the Y-axis positioning rod 51. The rear surface of the vertical block A52 is threaded with an auxiliary top screw A53. When the fast rail traction beam is placed on the upper surface of the four support members 4, the auxiliary top screw A53 can be tightened, and the auxiliary top screw A53 is used in conjunction with the Y-axis positioning rod 51 to clamp the front end of the fast rail traction beam from the Y-axis direction.

[0028] like Figure 1As shown, the front-end X-axis clamping mechanism 6 includes an X-axis positioning rod 61 and a vertical block B62. The X-axis positioning rod 61 and the vertical block B62 are fixedly connected to the base plate 1. The vertical block B62 is located on the left side of the X-axis positioning rod 61, and the left surface of the vertical block B62 is threaded with an auxiliary top screw B63. When the fast rail traction beam is placed on the upper surface of the four support members 4, the auxiliary top screw B63 can be tightened, and the auxiliary top screw B63 is used in conjunction with the X-axis positioning rod 61 to clamp the front end of the fast rail traction beam from the X-axis direction.

A nut C73 is threadedly installed on the outer surface of the screw C71. The nut C73 is used to press the pressure plate B72 toward the fast rail traction beam, so that the pressure plate B72 applies a vertical force to the front end of the fast rail traction beam, thereby clamping and positioning it.

[0030] During the process of adding sequence, the fast track traction beam can be first placed as follows: Figure 4 The support member 4 is placed on the bottom plate 1 (the position of the support member 4 is as shown in FIG. Figure 1 As shown), the rear end of the fast rail traction beam is located between the two side tightening washers 33, so that the front surface of its front end is in contact with the Y-axis positioning rod 51, and the right surface of its front end is in contact with the X-axis positioning rod 61. After that, the auxiliary top screw A53 and the auxiliary top screw B63 are tightened to lock the front end of the fast rail traction beam from the front, back, left and right directions respectively. Then, the pressure plate A22 and the pressure plate B72 are respectively sleeved on the outer surfaces of the screw A21 and the screw C71, and fixed with the nut A23 and the nut C73, the front and rear ends of the fast rail traction beam can be clamped and fixed in the vertical direction, thereby realizing all-round locking and positioning of the fast rail traction beam. Compared with the traditional processing and positioning method of the fast rail traction beam, this working fixture can omit the tedious processes of additional marking, rough processing and setting processing benchmarks for the machined castings, and is simpler to operate, which can reduce the processing flow and cost and improve processing efficiency.

[0031] In addition, combined Figure 1 and Figure 3 As shown, two small jacks 8 are fixedly installed on the upper surface of the base plate 1. The two small jacks 8 are respectively located below the outer ends of the pressure plate A22 and the pressure plate B72. The small jacks 8 can be used to lift the corresponding pressure plates to prevent the pressure plates from being easily deformed during the positioning of the fast rail traction beam.

[0032] In addition, in order to reduce the damage caused by the pressure plate during the compression process of the fast rail traction beam, such as Figure 1As shown, rubber pads 9 are fixedly installed on the lower surfaces of the inner ends of the pressing plates A22 and B72, and the rubber pads 9 can be used to contact the fast rail traction beam, thereby reducing the damage caused during the clamping and positioning process.

[0033] Finally, in order to facilitate the change of the use position of the entire fixture and the lifting operation, such as Figure 1 As shown, lifting rings 10 are fixedly installed on the left front and right rear of the upper surface of the base plate 1. The lifting rings 10 can be connected to the hooks of an external crane or lifting equipment, thereby allowing the entire clamp to be safely and efficiently transported to other required usage locations by lifting.
