[0016] The present invention will now be described in detail with reference to specific embodiments: like Figures 1 to 6 The rear fork assembly correction mold shown includes a base plate 1, a telescopic cylinder 2, a first quick clamp 3, a fork width inspection slider 33, a rear fork fixing block 4, a second quick clamp 5, an inner fork width slide block 53, and a disc brake inspection block 61. The first quick clamp 3, the second quick clamp 5, and the rear fork fixing block 4 are fixedly installed on the base plate 1. The base plate 1 is also fixedly installed with a first slide rail 31, a second slide rail 51, a cylinder seat 21, a first baffle 41, and a second baffle 7. The rear fork fixing block 4 and the first baffle 41 cooperate to form a contour positioning structure. The cylinder body of the telescopic cylinder 2 is fixedly installed on the cylinder seat 21, and a pressure plate 22 is fixedly installed on the piston rod of the telescopic cylinder 2. A first slider 32 and a second slider 52 are slidably mounted on the first slide rail 31 and the second slide rail 51, respectively. A fork width inspection slider 33 is fixedly mounted on the first slider 32, and an inner fork width slide 53 is fixedly mounted on the second slider 52. The pressure heads of the first quick clamp 3 and the second quick clamp 5 are fixedly connected to the fork width inspection slider 33 and the inner fork width slide 53, respectively. The top of the inner fork wide slide block 53 is fixedly installed with a third slide rail 62, and a third slider 63 is fixedly installed on the third slide rail 62. The detection block bracket 6 is fixedly installed on the third slider 63, and the disc brake inspection block 61 is screwed and fixedly installed on the detection block bracket 6. The first detection rod 34 can be slidably inserted and installed on the fork width inspection slider 33, and the second detection rod 54 and the third detection rod 55 can be slidably inserted and installed on the inner fork width slide block 53.

[0017] Alignment pads 8 are fixedly installed on both the front and rear sides of the base plate 1. After welding, the two sides of the rear fork assembly may become non-parallel. When the rear fork tube 91 of the rear fork assembly shifts upwards, a hammer is used to knock the upward-shifted rear fork tube 91 downwards until both sides are parallel. When the rear fork tube 91 of the rear fork assembly shifts downwards, a pry bar is used, with the alignment pads 8 as fulcrums, to pry the downward-shifted rear fork tube 91 up until both sides are horizontal. This alignment of the rear fork tube 91 facilitates the easy insertion of the second detection rod 54 and the third detection rod 55 to check whether the two sides of the rear fork assembly are aligned parallel.

[0018] Two limiting posts 64 are fixedly installed on the inner fork wide slide block 53 to limit the movement of the third slider 63, so as to prevent the third slider 63 from falling off the third slide rail 62.

[0019] The base plate 1 is provided with a positioning groove, and the first slide rail 31 and the second slide rail 51 are embedded in the positioning groove of the base plate 1 to increase the firmness of the first slide rail 31 and the second slide rail 51 after installation, thereby improving the straightness of the fork width inspection slider 33 and the inner fork width slide 53 when they slide left and right.

[0020] The rear fork assembly is clamped and fixed on the calibration mold. The front take-up arm 92 is installed in the fork fixing block 4 and the first baffle 41 to form a contour positioning structure. The piston rod of the telescopic cylinder 2 extends and pushes the pressure plate 22 to press and fix the front take-up arm 92 on the fork fixing block 4 and the first baffle 41. Pressing the first quick clamp 3 pushes the take-up arm fork width inspection slider 33 to move closer to the rear fork assembly along the first slide rail 31. The take-up arm fork width inspection slider 33 corrects the inner width of the front take-up arm 92. By inserting the first detection rod 34 through the hole of the take-up arm fork width inspection slider 33, the coaxiality of the two first holes 921 of the front take-up arm 92 is corrected. Press the second quick clamp 5, push the inner fork wide slide 53 along the second straight line 51 toward the rear fork assembly. The inner fork wide slide 53 tests whether the left and right hooks 93 can be inserted into its calibration groove. Then, insert the second detection rod 54 and the third detection rod 55 into the holes of the inner fork wide slide 53 to calibrate the coaxiality of the two second holes 931 and the two third holes 932 of the left and right hooks 93. Finally, slide the combination of the third slider 63, the detection block bracket 6, and the disc brake inspection block 61 along the third slide rail 62 until the disc brake inspection block 61 is located at the disc brake ear 94 to calibrate its position.
