Both the first sub-assembly 301 and the fourth sub-assembly 304 are two and are arranged oppositely for clamping the two sides of the first end 21 and the second end 22 of the side beam 2 back and forth.

[0085] In this embodiment, referring to Figure 1 and Figure 10 , the positioning assembly 20, the limiting assembly 40, the third sub-assembly 303, and the fourth sub-assembly 304 form a second positioning and clamping member 12. The number of the second positioning and clamping members 12 is two and they are arranged side by side at the middle position of the fixture platform 10 for clamping the middle part 23 of the side beam 2. Among them, the number of the fourth sub-assemblies 304 is four, two in a group and arranged oppositely. The number of the third sub-assemblies 303 is two, arranged oppositely and located on the right side of the fourth sub-assembly 304. The limiting assembly 40 and the positioning assembly 20 are respectively arranged close to the third sub-assembly 303.

[0086] In this embodiment, referring to Figure 1 and Figure 11 , a third positioning and clamping member 13 is further arranged between the first positioning and clamping member 11 and the second sub-assembly 302, and a first sub-assembly 301 is arranged between the first positioning and clamping member 11 and the third positioning and clamping member 13.

[0087] The third positioning and clamping member 13 includes a frame 110, a positioning assembly 20, a third sub-assembly 303, and a fourth sub-assembly 304. The third sub-assembly 303 and the fourth sub-assembly 304 arranged at the rightmost end of the third positioning and clamping member 13 share a part of the connection structure between the clamping arm 32 and the driving cylinder 34, and the remaining third sub-assemblies 303 and fourth sub-assemblies 304 are arranged alternately at intervals from left to right.

[0088] Among them, the first sub-component 301, the second sub-component 302, and the third sub-component 303 are mainly used to clamp the side beam 2 in the up and down directions. The fourth sub-component 304 is mainly used to clamp the side beam 2 in the front and back directions. The fixture 1 for the side beam 2 of the locomotive frame of the present application can meet the positioning and clamping of side beams with any length within the range of 0 - 6000 mm.

[0089] There is also a second embodiment of the fixture 1 for the side beam 2 of the locomotive frame of the present application. The fixture 1 for the side beam 2 of the locomotive frame in this second embodiment has a substantially same structure as that of the fixture 1 for the side beam 2 of the locomotive frame in Figures 1 to 11 the embodiment. Therefore, in the following description of the fixture 1 for the side beam 2 of the locomotive frame in this second embodiment, the structures already described in Figures 1 to 11 the embodiment will not be repeated. In addition, the same reference signs are marked for the structures that are the same as those of the fixture 1 for the side beam 2 of the locomotive frame described in Figures 1 to 11 the embodiment. Therefore, in the following description of this embodiment, the differences from the fixture 1 for the side beam 2 of the locomotive frame in Figures 1 to 11 the embodiment will be mainly described. Among them, for the fixture 1 for the side beam 2 of the locomotive frame in this second embodiment, the adjusting seat 31 of the clamping component 30 can be telescopically moved up and down to meet the needs of different positions.

[0090] The fixture 1 of the present application further includes a control system to control the fixture 1 to realize automatic welding of the side beam 2 of the locomotive frame by a welding robot.

[0091] The above is a detailed description of several exemplary embodiments of the fixture 1 for the side beam 2 of the locomotive frame proposed in the present application. The following will describe in detail the using process of the fixture 1 for the side beam 2 of the locomotive frame proposed in the present application.

[0092] Combined with the attached Figures 1 to 11 , the using process of the fixture 1 for the side beam 2 of the locomotive frame proposed in the present application is as follows:

[0093] The first end 21, the second end 22, an intermediate part 23 of the side beam 2 of the locomotive frame, a first inclined part 24 connecting the intermediate part 23 and the first end 21, and a second inclined part 25 connecting the intermediate part 23 and the second end 22 are respectively arranged on the fixture platform 10 of the fixture 1. The side beam 2 of the locomotive frame is positioned and limited by the positioning component 20 and the limiting component 40. Then, the control system controls the driving cylinder 34 to drive the clamping arm 32 to move, and the clamping arm 32 drives the adjusting block 33 to move to clamp the side beam 2. When clamping, the clamping force can be controlled to be consistent on the front and back sides of the side beam 2 to avoid deformation of the side beam 2 and affect the welding accuracy. Then, the robot performs automatic welding to complete the welding of the side beam 2 of the locomotive frame.
