The rotating shaft 5 extends in the front-to-back direction, and the rear end of the rotating shaft 5 is connected to the fixed frame 4.

[0025] In this embodiment, the fixed frame 4 is a horizontal U-shaped frame, the open end of the U-shaped frame is fixedly connected to the fixed plate, the rear end of the rotating shaft 5 is installed at the closed end of the U-shaped frame, and a displacement adjustment space is formed in the U-shaped frame.

[0026] The indexing type positioning cone 10 is sleeved on the rotating shaft 5 and forms a rotational fit and an axial sliding fit therewith.

[0027] In this embodiment, the dividing type positioning cone 10 is divided into a first cylindrical section 101, a conical section 105, a second cylindrical section 102, a third cylindrical section 103 and a fourth cylindrical section 104 from front to back, the front end of the conical section 105 is a large diameter end, and the rear end is a small diameter end; the diameter of the first cylindrical section 101 is larger than the large diameter end of the conical section 102; the diameter of the third cylindrical section 103 is smaller than the diameters of the second cylindrical section 102 and the fourth cylindrical section 104, forming a circular groove; the second cylindrical section 102, the third cylindrical section 103 and the fourth cylindrical section 104 are located in the displacement adjustment space.

[0028] The rotating base 3 and the fixed plate 2 are provided with through holes that match the indexing positioning cone 10. The through holes on the rotating base 3 are tapered holes that match the conical section 105.

[0029] The indexing transfer table 9 is fixedly mounted on the front end of the indexing positioning cone 10, the rotating shaft 5 passes through the indexing transfer table 9 and extends forward, and a limit table is provided at the front end of the rotating shaft 5, and the return spring 6 is sleeved on the rotating shaft between the limit table and the indexing transfer table 9. Both ends of the return spring 6 are in contact with the indexing transfer table 9 and the limit table respectively.

[0030] Four adapter plates 90 are evenly arranged on the indexing adapter table 9 around the rotating shaft 5; four positioning grooves are arranged on the rotating base 3 around its through hole, and the positioning grooves correspond to the adapter plates 90 one by one; and a positioning table 100 matching the positioning grooves is arranged on the indexing positioning cone 10.

[0031] The positioning and separation mechanism acts on the indexing positioning cone 10, and controls the indexing positioning cone 10 to move forward and backward on the rotating shaft 5, so that the positioning platform 100 on the indexing positioning cone is separated or engaged with the positioning groove on the rotating base 3, completing the rotational displacement of the adapter plate 90 on the indexing adapter platform 9.

[0032] Specifically, the positioning and separation mechanism includes an ejection locker 8 extending left and right, the left end of the ejection locker 8 is rotatably connected to the fixed plate 2 through the first pin shaft 71, and two sets of limit devices are fixed on the upper side of the ejection locker 8, and the two sets of limit devices are respectively located on the left and right sides of the rotating shaft 5 and cooperate with the fourth cylindrical section 104.

[0033] Each set of limiting devices includes a locking limiting block 81 with a higher height and an ejection limiting block 82 with a lower height. The locking limiting block 81 is located at the front side of the ejection limiting block 82. The opposing surfaces of the locking limiting block 81 and the ejection limiting block 82 are parallel inclined planes, and the fourth cylindrical section 104 is located between the two parallel inclined planes.

[0034] The ejector locker 8 swings up and down around the first pin shaft 71, and acts on the fourth cylindrical section 104 through two parallel inclined surfaces, thereby driving the indexing positioning cone 10 to move back and forth on the rotating shaft 5, so that the positioning platform 100 on the indexing positioning cone is separated or engaged with the positioning groove on the rotating base 3, completing the rotational displacement of the adapter plate 90 on the indexing adapter platform 9, thereby realizing rapid displacement.

[0035] The movable transfer mechanism is detachably fixedly mounted on the transfer plate 90, and the movable transfer mechanism includes a positioning block 12, a positioning locking mechanism, and a positioning pin. In this embodiment, the positioning block 12 is approximately Z-shaped, wherein the upper horizontal portion forms an upper mounting portion, and the lower horizontal portion forms a lower mounting portion, and the upper mounting portion and the lower mounting portion have a height difference, and the lower mounting portion is detachably fixedly connected to the transfer plate 90 through the positioning locking mechanism, and the positioning pin is installed on the upper mounting portion.

[0036] Specifically, the positioning locking mechanism includes a positioning locking pin 13, a second pin shaft 72 and a clamping rod 14. The lower mounting portion and the adapter plate 90 are correspondingly provided with mounting holes. The positioning locking pin 13 passes downward through the mounting holes on the lower mounting portion and the adapter plate. The two ends of the positioning locking pin 13 are respectively provided with an upper limit portion and a lower limit portion. The upper limit portion is in contact with and cooperates with the lower mounting portion. The positioning locking pin 13 between the lower limit portion and the adapter plate 90 is set as a circular groove to form a locking action area.

[0037] One end of the clamping rod 14 is rotatably connected to the lower mounting portion through the second pin shaft 72. The clamping rod 14 is provided with a fork-shaped oblique wedge clamping block 140, and the fork-shaped oblique wedge clamping block 410 cooperates with the positioning locking pin 14 in the locking action area. The clamping rod 14 swings, enters the locking action area through the fork-shaped oblique wedge clamping block 410 and acts on the lower limit portion, driving the positioning locking pin 13 to move downward, and locking the lower mounting portion and the adapter plate 90.

[0038] Specifically, the locating pin is an eccentric clamping locating pin 16, which cooperates with the locating hole of the vehicle body. The lower end of the eccentric clamping locating pin 16 is downwardly connected to an adjustment column eccentrically arranged therewith. The adjustment column passes downward through the upper mounting part and is provided with a locking block 18 at the lower end (the locking block 18 is square, which is convenient for rotating and tightening with tools). A limit block 15 is sleeved on the adjustment column between the locking block 18 and the upper mounting part; in the initial state, a locking gap is retained between the limit block 15 and the locking block 18.

[0039] A sleeve 17 is coaxially connected to the lower side of the eccentric clamping locating pin 16. The sleeve 17 has a locating protrusion that cooperates with the limiting groove on the eccentric clamping locating pin. The lower surface of the sleeve 17 is an inclined surface, the lower end of the inclined surface contacts the upper mounting part, and the distance between the upper end of the inclined surface and the upper mounting part is slightly higher than the thickness of the vehicle body mounting part.

[0040] The limit block 15 acts with the eccentric clamping positioning pin 16 to ensure that the eccentric clamping positioning pin 16 can be accurately positioned and clamped. When clamping, the eccentric clamping positioning pin 16 rotates together with the cushion sleeve 17. Since the cushion sleeve 17 is an inclined surface, the eccentric part locks the parts around the vehicle body positioning block to prevent the vehicle body from moving during transportation.

[0041] In order to effectively and quickly distinguish the positioning mechanism in use and eliminate errors caused by the large number of vehicle models during manual identification, a coding nameplate 110 is provided on the adapter plate of the fixed adapter mechanism, and the coding nameplate 110 is provided with a first type of number code; a coding nameplate 111 is provided on the positioning block 12 of the movable adapter mechanism, and the coding nameplate 111 is provided with a second type of number code. The first type of number code and the second type of number code are combined to form a group of vehicle body transfer use codes, and different vehicle models use different code groups.

[0042] Regarding the first type numbering code and the second type numbering code, this embodiment proposes a coding rule, but the coding rule is not limited thereto.

[0043] The coding nameplate 110 is installed on the corresponding adapter plate 90 on the indexing adapter 9. The nameplate is a 2-digit code. The first digit is a letter, with lowercase on the left and uppercase on the right. The letters A, B, and C represent different indexing adapters 9 on the vehicle body stand, and the second digit is a number. 1, 2, 3, and 4 represent the adapter plates of the indexing adapter 9, respectively. The coding nameplate 111 is installed on the positioning block 12. The coding rules are the same as the previous one, but the digital part can be increased as the vehicle model requirements.

[0044] When a new vehicle body is added, a new positioning and clamping system is formed by using the fixed transfer mechanism on the original test bench and the movable transfer mechanism. At this time, the corresponding number of the fixed transfer mechanism and the corresponding number of the movable transfer mechanism are used to become a set of vehicle body transfer usage codes, and different vehicle models use different code groups.

[0045] The working principle of the present invention is as follows: When switching the vehicle model, it is only necessary to disengage the clamping rod 14 from the positioning locking pin 13, so that the positioning locking pin 13 can be disengaged from the corresponding adapter plate on the indexing transfer platform 9, that is, the movable transfer mechanism is removed; then the locking limit block 81 of the ejection locker 8 is separated from the fourth cylindrical section 104 of the indexing positioning cone 10, and the ejection limit block 82 of the ejection locker 8 is continued to move the fourth cylindrical section 104 and the indexing positioning cone 10 toward the fixed frame 4, so that the positioning platform 100 on the indexing positioning cone 10 is separated from the positioning groove on the rotating base 3, and the indexing transfer platform 9 is rotated. 90 degrees to put the new adapter plate in place, pull the ejection locker 8 to separate the ejection limit block from the fourth cylindrical section 104 of the indexing positioning cone 10, and under the action of the reset spring 6, the positioning platform on the positioning cone 10 cooperates with the positioning groove on the fixed block 2 for positioning, and continue to move and use the ejection locker 8 to make the locking limit block 81 cooperate and lock with the fourth cylindrical section 104 of the indexing positioning cone 10 to complete the positioning switching of the fixed adapter mechanism; then install the new movable adapter mechanism on the corresponding adapter plate 90 on the indexing adapter table 9 again, and lock the clamping rod 14 with the positioning locking pin 13.

[0046] When the vehicle type is switched, the vehicle body is installed in place, and a tool is used to rotate the lower locking block 18 of the eccentric clamping locating pin 16. Since the locating pin is an eccentric pin, the eccentric clamping locating pin 16 rotates together with the cushion sleeve 17. Since the cushion sleeve 17 is an inclined surface, the eccentric part locks the parts around the vehicle body locating block to prevent the vehicle body from moving during transportation.

[0047] This device is suitable for the production of various specifications of vehicle bodies. It also uses conical matching and inclined clamping to eliminate the influence of paint film thickness on accuracy during multiple coatings, thereby reducing repair and maintenance costs.

[0048] The invention has a sophisticated and simple structure, is easy to adjust, and can be quickly adapted to various specifications of vehicle bodies, greatly saving modification costs and modification cycles, achieving rapid delivery of newly developed vehicle bodies, saving new vehicle production preparation time, and reducing investment. At the same time, it is fast and accurate in use, thereby improving production efficiency.
