DETAILED DESCRIPTION

[0025] The automobile electric steering gear assembly inspection device comprises a frame 1, a transmission plate chain line 3, a traveling bottom plate 4, a traveling clamp seat 5 and a support plate 8 (see the attached manual). Figure 1 , 2 and 3).

[0026] Two sets of transverse plate chains 2 are symmetrically arranged on the frame 1; a conveyor plate chain line 3 is installed at one end of the transverse plate chain 2. The transverse plate chain 2 and the conveyor plate chain line 3 are purchased equipment. A plurality of accompanying bottom plates 4 are installed on the conveyor plate chain line 3; the accompanying bottom plates 4 are equipped with accompanying clamp seats 5 (see the attached manual). Figure 8 The portable clamp seat 5 is equipped with a positioning plate 21 and a support seat 22; the support seat 22 is equipped with a locking bolt 23. During operation, the workpiece to be inspected can be fixed on the portable clamp seat 5 through the positioning plate 21 and the locking bolt 23 (see the appendix of the manual). Figure 6 , 8 ).

[0027] The interior of the conveyor plate chain line 3 is equipped with a reversing plate chain assembly 6 through a lifting cylinder; the reversing plate chain assembly 6 corresponds to the transverse plate chain 2 (see the attached manual). Figure 2 and 3 ). When the conveyor plate chain line 3 drives the accompanying bottom plate 4 to move above the reversing plate chain assembly 6, the reversing plate chain assembly 6 can push the accompanying bottom plate 4 upward with the cooperation of the lifting cylinder to make it flush with the transverse plate chain 2. Then the reversing plate chain assembly 6 can move to transport the accompanying bottom plate 4 to the transverse plate chain 2.

[0028] A support plate 8 is installed between the two sets of transverse plate chains 2 through a lifting cylinder 7 (see the attached manual). Figure 3 ). The lifting cylinder 7 can drive the support plate 8 to move up and down.

[0029] The left end of the support plate 8 is provided with a left length detection block 9 and a left minimum swing angle detection plate 10; the right end of the support plate 8 is provided with a right minimum swing angle detection plate 11 and a right length detection block 12 (see the attached manual). Figure 7A plurality of calipers 20 are installed at intervals on the support plate 8 between the left minimum swing angle detection plate 10 and the left length detection block 9 (see the attached manual). Fig. 9 The right minimum swing angle detection plate 11 and the left minimum swing angle detection plate 10 are both provided with detection notches 24 (see the attached manual). Fig. 9 and 11 ).

[0030] A detection bracket 15 is mounted on the support plate 8 on one side of the right minimum swing angle detection plate 11 through a slide rail 13 and a slide seat 14 (see the attached manual). Figure 7 ). The upper end of the detection bracket 15 is equipped with an input end phase angle detection rod 18 through a reset spring 17; the detection bracket 15 at the lower end of the input end phase angle detection rod 18 is equipped with an input end flat square phase detection rod 19 through a reset spring 17. During operation, the input end phase angle detection rod 18 and the input end flat square phase detection rod 19 can be manually pressed to overcome the elastic force of the reset spring 17 to complete the detection.

[0031] An adsorption magnetic rod 16 is installed on the frame 1 on one side of the support plate 8 through a push cylinder; an adsorption iron block is installed on the slide 14 on one side of the adsorption magnetic rod 16; and a limit block 25 is installed at the end of the slide rail 13 on one side of the slide 14. During operation, when the adsorption magnetic rod 16 approaches the slide 14 under the push of the push cylinder, the adsorption magnetic rod 16 can be connected to the slide 14 through the adsorption iron block under the action of magnetic force. In this way, when the adsorption magnetic rod 16 moves, it can drive the slide 14 to slide together. When the adsorption magnetic rod 16 drives the slide 14 to move backward until the end of the slide rail 13 contacts the limit block 25, the slide 14 will stop moving. At this time, the adsorption magnetic rod 16 will continue to move backward and will be out of contact with the slide 14.

[0032] When the vehicle electric steering gear assembly inspection device is working, when the accompanying clamp seat 5 with the workpiece is moved to the top of the reversing plate chain assembly 6 under the action of the conveying plate chain line 3, the reversing plate chain assembly 6 can push the accompanying bottom plate 4 upward to make it flush with the transverse plate chain 2 under the cooperation of the lifting cylinder. Then the reversing plate chain assembly 6 can move the accompanying bottom plate 4 to the transverse plate chain 2.

[0033] After the above work is completed, the transverse plate chain 2 moves to transport the accompanying bottom plate 4 together with the workpiece to the top of the support plate 8. Then the lifting cylinder 7 drives the support plate 8 to move up so that it pushes the accompanying bottom plate 4 upward and disengages from the transverse plate chain 2.

[0034] At this time, the two ends of the workpiece are inserted into the right minimum swing angle detection plate 11, the right length detection block 12, the left length detection block 9 and the left minimum swing angle detection plate 10. If they can be inserted, it means that the length of the workpiece is qualified and the minimum swing angle is qualified, otherwise it is an unqualified product.

[0035] After the above work is completed, when the adsorption magnetic rod 16 approaches the slide 14 under the push of the push cylinder, the adsorption magnetic rod 16 can be connected to the slide 14 through the adsorption iron block under the action of magnetic force, and push the slide 14 and the detection bracket 15 close to the workpiece and then stop. Then manually press the input end phase angle detection rod 18 and the input end flat square phase detection rod 19 to overcome the elastic force of the reset spring 17 to complete the input end phase angle and flat square phase detection angle detection. If the input end phase angle detection rod 18 and the input end flat square phase detection rod 19 can be smoothly inserted, it means that the input end phase angle and flat square phase detection angle of the workpiece are qualified, otherwise it is an unqualified product.

[0036] After completing the detection of the input end phase angle and the flat square phase detection angle, the adsorption magnetic rod 16 drives the slide 14 to move backward. During this process, when the slide 14 contacts the limit block 25 and stops, the adsorption magnetic rod 16 continues to move backward and breaks contact with the slide 14 before resetting.

[0037] After the magnetic rod 16 is reset, each caliper 20 is then held in turn to complete the inner rod hexagonal detection, the nut hexagonal detection and the outer rod flat square detection. If the detection is qualified, the workpiece is a qualified product, otherwise it is an unqualified product.

[0038] After the inspection is completed and marked, the lifting cylinder 7 drives the support plate 8 to move down so that the accompanying bottom plate 4 contacts the transverse plate chain 2, and then the transverse plate chain 2 drives the accompanying bottom plate 4 to move to the reversing plate chain assembly 6, and then the reversing plate chain assembly 6 moves down so that the accompanying bottom plate 4 falls on the conveying plate chain line 3, and then the conveying plate chain line 3 transports it to the next process. At this point, the automobile electric steering gear assembly inspection device can enter the next working cycle.

[0039] The automobile electric steering gear assembly inspection device can realize loading and unloading operations in a mechanized manner, thereby solving the problems of high labor intensity and low detection efficiency in the existing automobile electric steering gear assembly inspection method, and is particularly suitable for the needs of automobile electric steering gear assembly inspection.
