[0005] An anti-misalignment pin 16 is installed on the upper part of the left fixed bent plate 12 located on one side of the sliding block 8 .

[0006] The two ends of the sliding shaft 6 are located outside the left fixed curved plate 12 and the right fixed curved plate 4 and are provided with shaft retaining rings 13 .

[0007] The cylinder 2 is mounted on a cylinder washer 3 , and the cylinder washer 3 is fixed on the base plate 1 .

[0008] A propulsion block 7 is installed at the front end of the cylinder spindle 5 of the cylinder 2.

[0009] A spring 10 is installed on the sliding shaft 6 between the sliding block 8 and the left fixed bent plate 12 .

[0010] The error-proof assembly mechanism of the balancer of the utility model can be used in conjunction with an automatic torque wrench to prevent omissions in manual assembly and prevent assembly angle errors. The assembly parts can be replaced quickly and conveniently without manual fixation, thereby improving production efficiency and reducing error rates. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The balancer anti-misassembly mechanism of the utility model is as follows Figure 1 and Figure 2 As shown, a left fixed bent plate 12 and a right fixed bent plate 4 are installed on the base plate 1, and two ends of the two sliding shafts 6 are respectively installed on the left fixed bent plate 12 and the right fixed bent plate 4, and two ends of the sliding shaft 6 are located outside the left fixed bent plate 12 and the right fixed bent plate 4 to install shaft retaining rings 13, and a slider 8 is installed on the sliding shaft 6, and positioning pins 9 are provided at the four corners of the upper side of the slider 8; a spring 10 is installed on the sliding shaft 6 between the slider 8 and the left fixed bent plate 12, and a cylinder 2 is installed on the base plate 1 on one side of the right fixed bent plate 4, and the cylinder 2 is installed on the cylinder washer 3, and the cylinder washer 3 is fixed on the base plate 1, and the front end of the cylinder spindle 5 of the cylinder 2 is located on the right side of the slider 8, and the front end of the cylinder spindle 5 of the cylinder 2 is installed with a propulsion block 7; a positioning block 11 is installed on the left fixed bent plate 12 corresponding to the left side of the slider 8, and an anti-misalignment pin 16 is installed on the upper part of the left fixed bent plate 12 on one side of the slider 8, and the position of the anti-misalignment pin 16 matches the part to be assembled.

[0015] The assembly mechanism is used in the assembly line, and cooperates with the automatic bolt tightening device to automatically tighten the bolts to prevent omissions and prevent assembly angle errors. During operation, the parts to be assembled are placed on the slider 8, and the parts to be assembled are positioned by the positioning pins 9; the slider 8 passes through the two sliding shafts 6 to move horizontally, and the two sliding shafts 6 are fixed by the left and right fixed bent plates 4 and 12 and the shaft retaining ring 13, and the two fixed bent plates are tightened on the bottom plate 1 with the bent plate fixing bolts 15; the bottom plate 1 is fixed on the assembly line platform by bolts; a cylinder 2 is placed at one end of the slider, and the cylinder 2 is fixed to the bottom plate 1 by the cylinder pad 3; the cylinder 2 cooperates with the cylinder shaft 5 and the propulsion block 7 to push the slider 8 to the other end, and a positioning block 11 is installed on the fixed bent plate 12 at the other end with the positioning block fixing bolts 14. After the slider is pushed and close to the positioning block 11, it is fixed by the propulsion force of the cylinder; two anti-error pins 16 are installed on the bent plate 12, and the assembled parts can only ensure the correct assembly angle by passing through these two anti-error pins 16. At this time, assembly begins, and the parts are fixed by an automatic torque wrench; after assembly is completed, the cylinder is depressurized, the slider is pushed back to its original position by the spring 10, the assembled assembly is removed, and the next set of parts is placed for assembly.
