[0029]The two sides of the large-diameter through-shaft 302 in the vertical direction are respectively fixed with a left locking handle 306 and a right locking handle 307 by screws, and two large die springs 308 and two A small die spring 309 is also slidably connected to the inner side of the housing with two horizontal small diameter through shafts 303 , a small cam baffle 305 is fixed on the outside of the two horizontal direction small diameter through shafts 303 , and two horizontal large diameter through shafts 301 A large cam baffle 304 is fixed on the outer side of the shaft, and the large diameter in the horizontal direction penetrates the outer side of the shaft 301 and is located between the large die spring 308 and the small die spring 309. A spring front stop 310 is fixed. The space between the side blocks 310 is used to limit the expansion and contraction of the four large die springs 308. The small diameter in the horizontal direction penetrates the outside of the shaft 303 and is located between the large die spring 308 and the small die spring 309. A spring fixing stop 311 is fixed, and the large cam The left side of the baffle 304 fits the small die spring 309, the right side fits the large cam 312, and the left side of the small cam baffle 305 fits the large and small die spring 309, and the right side fits the small cam 313, thereby making the structure of the mechanism The design is reasonable and compact, which achieves the advantages of light weight, convenient disassembly and assembly, and low processing cost, can meet the requirements of various performance indicators, and effectively prevent the clamping force of the driving wheel from being unable to control the occurrence of damage to the guide rail and wear of the driving wheel 103. Overall improved welding quality and efficiency;
[0030] see Figure 1-4 , Image 6 As shown, in this embodiment, the interior of the four driven wheel sleeves 201 are provided with stepped holes, the interior of the four driven wheel sleeves 201 and at the top and bottom of the stepped holes are equipped with plane bearings 203, the driven wheel The sleeve 201 is rotatably connected to the driven wheel 202 through the plane bearing 203, which can reduce the frictional force generated between the driven wheel 202 and the driven wheel sleeve 201 when the driven wheel 202 rotates, thereby prolonging the service life and greatly improving the use of the driven wheel 202. Effect.
[0031] During use, by rotating the left locking handle 306 and the right locking handle 307 at the same time, the large cam 312 on the vertical large diameter through shaft 302 is driven to rotate, and when the stroke of the large cam 312 reaches half, the large cam baffle is squeezed 304 further drives the driven wheel connecting block 205 and the driven wheel sleeve 201 to move laterally, so that the driven wheel 202 is clamped on the guide rail, and the left locking handle 306 and the right locking handle 307 are further rotated and rotated to drive the small cam 313 to rotate and squeeze Press the small cam baffle 305 to drive the driving wheel assembly 100 to move laterally, so that the driving wheel 103 is clamped on the guide rail. At this time, the stroke of the large cam 312 reaches the maximum, and the tension force of the driven wheel 202 can be obtained. It can complete the up and down walking of the welding trolley on the guide rail.
