[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The present application will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to explain the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only portions relevant to the relevant utility model are shown in the accompanying drawings. It should be noted that the embodiments and features in the embodiments of this application may be combined with each other unless there is a conflict.

[0026] The utility model provides an eccentric positioning clamping device for a car back panel, such as Figure 2 and Figure 3 As shown, the automobile back panel 100 includes a matching groove surface 200, and an eccentrically arranged matching pile platform group is provided on the matching groove surface 200. The matching pile platform group includes four matching pile platforms 300. Any matching pile platform 300 includes a pile platform base 310 and a pile platform matching column 320 arranged on the pile platform base. An open horizontal groove chamber 400 is provided in the pile platform base 310. The four matching pile platforms form two opposing groups. The opening directions of the groove chambers of the two pile platform bases of any opposing group are relatively set, and the open opposing directions of the two opposing groups are parallel.

[0027] The conventional picking device adopts clamping for the mating pile 300 or negative pressure adsorption for the flat part of the mating groove surface 200 , and its picking position accuracy is poor and it is easy to cause clamping damage to the mating pile 300 .

[0028] In view of this situation, this case proposes an eccentric positioning clamping device, such as Figures 1 to 3As shown, it comprises a turnover base 1, two two-way clamping mechanisms 2 corresponding to the one-to-one arrangement of the alignment group are arranged on the turnover base 1.

[0029] The two-way clamping mechanism 2 comprises a clamping base 3 located between the two corresponding alignment groups of the adapter pile platform, and two matching top blocks 4 corresponding to the one-to-one arrangement of the slot chamber 400 are arranged on the clamping base 3. Any matching top block 4 has a linear displacement towards the slot chamber.

[0030] Specific implementation process and principle explanation:

[0031] First, the eccentric alignment pickup for the adapter pile platform group is adopted. When picking up, the two clamping bases 3 are respectively located between the two adapter pile platforms of the corresponding alignment group, so that the matching top block 4 is aligned with the respective slot chamber.

[0032] At this time, the linear displacement driving of the matching top block 4 is performed, so that the matching top block 4 is inserted into the slot chamber, thereby realizing the outward expansion locking of the four positions, and thus realizing the outward expansion pickup, which will not cause clamping damage to the adapter pile platform 300.

[0033] In one embodiment, a limiting matching block 5 corresponding to and cooperating with the matching top block is arranged on the clamping base 3, and a limiting matching space 50 for cooperating with the pile platform adapter column is formed between the limiting matching block and the matching top block.

[0034] That is, the adapter cooperation for the slot chamber 400 is realized, and the free end abutting limiting of the pile platform adapter column 320 is realized, so that the pickup is more reliable and stable, and the turnover is more reliable.

[0035] In one embodiment, the free end of the matching top block and the free end of the limiting matching block are respectively provided with a guide inclined wall 6.

[0036] Specifically, when the turnover base 1 is turned to the position, there may be a certain height deviation, at this time, the guide inclined wall 6 can realize the guide, and in the linear displacement process, it forces the back plate to produce a corrective upward displacement, thereby reducing the pickup positioning accuracy requirement and meeting the accuracy requirement after pickup.

[0037] In one embodiment, the clamping base 3 comprises two displacement driving sources 30 arranged at intervals on the turnover base 1, and any displacement driving source is provided with a linkage block 7, and the limiting matching block and the matching top block are arranged on the linkage block.

[0038] Specifically, the linkage block 7 can realize the carrying of the limiting matching block and the matching top block, and the displacement driving source can realize the linear displacement driving of the linkage block 7.

[0039] It should be noted that, in a preferred embodiment, the limiting matching block has a lifting and lowering adjustment displacement, which can be freely adjusted according to the height of the pile platform matching column 320 to meet the adaptation requirements of various specifications.

[0040] In a specific embodiment, the displacement driving source 30 includes a driving source base 31, on which is provided a telescopic driving end 311 that is transmission-connected to the linkage block, and two guide channels 312 arranged on both sides of the telescopic driving end. The linkage block 7 is provided with two guide columns 70 that are slidingly matched with the guide channels in a one-to-one correspondence.

[0041] This design ensures the guiding accuracy of linear displacement and makes linear matching displacement more reliable.

[0042] In a specific embodiment, the limiting matching block and the matching top block are respectively detachably connected to the linkage block.

[0043] That is, it can be adapted according to the specification differences of the matching pile platform 300, which improves the versatility and facilitates the replacement.

[0044] In a specific embodiment, the turnover base 1 is provided with an axis matching channel 10 for matching with the axis of the robot arm. Such a design satisfies the matching between the axis of the robot arm.

[0045] As can be seen from the above description, the eccentric positioning clamping device for automobile backboards in this utility model utilizes an outward-expanding pickup structure with offset alignment, ensuring stable and reliable pickup without causing clamping damage. It can achieve a certain degree of guidance and adjust the floating position of the backboard, thereby reducing the alignment accuracy requirements and meeting the positional accuracy requirements for the backboard after pickup. The overall design is compact and ingenious, easy to construct, convenient to install, and ensures smooth and efficient pickup operations.

However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.
