The bushing hole position detection pin 28 is controlled to move horizontally by the bushing hole position detection cylinder 27. The bushing hole position detection pin 28 is used to detect the inner hole of the bushing 34.

[0032] The bushing hole position detection cylinder 27 is horizontally mounted on the upper end of the bushing hole position support 26. A horizontally sliding slide 29 is installed on the upper end of the bushing hole position detection cylinder 27. The piston rod of the bushing hole position detection cylinder 27 is connected to one end of the slide 29. The bushing hole position detection pin 28 is fixed on the upper part of the slide 29.

[0033] A stop block 30 is provided on the side of the second slide block 29. On both sides of the stop block 30, a contact sensor 31 is installed on the side of the bushing hole position support 26. The stop block 30 moves back and forth between the two contact sensors 31. The two contact sensors 31 are respectively at two positions of the second slide block 29. When the stop block 30 contacts one of the contact sensors 31, it is the first position, and the first position is the standby working position of the bushing hole position detection pin 28. When the stop block 30 contacts the other contact sensor 31, it is the second position, and the second position is the working position where the bushing hole position detection pin 28 is inserted into the inner hole of the bushing 34. The setting of the stop block 30 and the two contact sensors 31 can realize the automatic detection of the bushing hole position. When detecting, if the contact sensor 31 at the second position gives feedback that the stop block 30 is contacted, the bushing hole position is qualified; otherwise, if the contact sensor 31 at the second position does not contact the stop block 30, the bushing hole position is unqualified. The feedback information of the contact sensor 31 is transmitted to a computer or a processor for summarization, and finally the detection result is obtained. Of course, it is also possible to visually check whether the bushing hole position detection pin 28 is inserted into the inner hole of the bushing 34 manually.

[0034] A stop block 30 is also provided on the side of the first slide block 16. On both sides of the stop block 30, a contact sensor 31 is installed on the side of the outer rear point support 5 of the H-arm. The stop block 30 moves back and forth between the two contact sensors 31. The two contact sensors 31 are respectively at two positions of the first slide block 16. When the stop block 30 contacts one of the contact sensors 31, it is the first position, and the first position is the standby working position of the outer rear point hole position positioning pin 7 of the H-arm. When the stop block 30 contacts the other contact sensor 31, it is the second position, and the second position is the working position where the outer rear point hole position positioning pin 7 of the H-arm is inserted into the rear point hole position 38. The setting of the stop block 30 and the two contact sensors 31 can realize the automatic detection of the rear point hole position 38. When detecting, if the contact sensor 31 at the second position gives feedback that the stop block 30 is contacted, the rear point hole position 38 is qualified; otherwise, if the contact sensor 31 at the second position does not contact the stop block 30, the rear point hole position 38 is unqualified. The feedback information of the contact sensor 31 is transmitted to a computer or a processor for summarization, and finally the detection result is obtained. Of course, it is also possible to visually check whether the outer rear point hole position positioning pin 7 of the H-arm is inserted into the rear point hole position 38 manually.

[0035] The contact sensor 31 belongs to an existing component and can be directly purchased on the market.

[0036] The pressing device 11 selects a clamping cylinder of AirTAC brand. This clamping cylinder can be directly purchased on the market and belongs to an existing component, so the specific structure will not be elaborated in detail.

[0037] On the upper end of the bottom plate 1, a limit baffle 32 is installed on the outside of each first pillar 10 to limit the position of the left side of the rear suspension H-arm.

[0038] like Figure 6 As shown, taking the left rear overhang H-arm as an example, the testing steps are explained as follows: The completed left rear overhang H-arm is placed on the support protrusion 15 at the upper end of the support column 10, support column 2 13, and rear point bracket 14. The left side of the left rear overhang H-arm is limited by the limiting baffle 32. The connecting arm 37 with the rear point hole 38 is placed on the support protrusion 15, and the end of the connecting arm 37 rests against the front end face of the end face reference block 19. The cylinder 16 is activated, and the cylinder 16 controls the rear point hole positioning pin 7 on the outer side of the H-arm to... The end plug 17 moves backward, causing the locating pin 7 at the rear point hole on the outer side of the H-arm to insert into the rear point hole 38. The end plug 17 presses against the connecting arm 37 with the rear point hole 38. Then, cylinder 2 3 is activated, and cylinder 2 3 controls the locating pin 4 at the front point hole on the outer side of the H-arm to insert into the front point hole 36 of another connecting arm 37, thus limiting the entire left rear suspension H-arm. Then, the clamping device 11 is used to press down on the upper end of the left rear suspension H-arm, thus fixing the entire left rear suspension H-arm. Then, the start... Activate the two bushing hole position detection devices 12. If both bushing hole position detection pins 28 can be inserted into the inner hole of the corresponding bushing 34, the position accuracy of the left rear suspension H-arm bushing hole is qualified. Conversely, if only one bushing hole position detection pin 28 is not inserted into the corresponding bushing 34, the position accuracy of the left rear suspension H-arm bushing hole is unqualified. Next, activate the rear stabilizer bar connecting rod connection hole position detection device 8. The connecting hole position detection cylinder 21 controls the connecting hole position detection column 22 to slide upward. If the connecting hole position detection column 22 can be inserted into the rear stabilizer bar connecting rod connection hole 35, the position accuracy of the rear stabilizer bar connecting rod connection hole 35 is qualified. Otherwise, it is unqualified. Finally, activate the two hardness detection devices 9. The hardness detection cylinder 25 controls the hardness tester 22 to move outward so that the upper end of the hardness tester 22 presses against the part that needs to be tested for hardness. The hardness is judged based on the value of the hardness tester 22. Only when all the above tests are qualified can the left rear suspension H-arm be considered a qualified product.

[0039] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.
