[0002] When assembling a car fender, it needs to have a relative position accuracy requirement with the front door, A-pillar and hood of the car body. The existing assembly method usually uses manual positioning tooling to position the fender and several parts of the car body separately.

[0057] Reference Figures 1 to 14An embodiment of the utility model provides a clamping and positioning device for a plug block between two panels, which can be applied to a floating positioning mechanism. The clamping and positioning device for the plug block between the two panels is a part of the floating positioning mechanism, and the floating positioning mechanism is used to realize the positioning tooling during the assembly between the fender and the vehicle door.

[0058] The floating positioning mechanism includes a mechanism positioning portion 100 , a mechanism clamping portion 200 and a floating device 300 .

[0059] The mechanism positioning portion 100 includes a first frame 110 and a plurality of positioning devices 120 disposed on the first frame 110 .

[0060] The mechanism clamping part 200 comprises a second frame 210 and flip arms 220 arranged on the left and right sides of the second frame 210 . The flip arms 220 can flip around the front and back directions. A plurality of clamping devices 230 are arranged on the second frame 210 and the flip arms 220 .

[0061] The first frame 110 and the second frame 210 are connected by the floating device 300 , so that the second frame 210 can float on the first frame 110 in the forward, backward, left and right directions.

[0062] Reference Fig.15 The floating positioning mechanism is used for accurate positioning between the fender 910 and various parts of the vehicle body, especially the door 920. Among them, the positioning mechanism can be positioned on the vehicle body through the plurality of positioning devices 120 of the mechanism positioning part 100. Since the fender 910 and the door 920 are divided into two groups, the mechanism clamping part 200 has two left and right flip arms 220. The flip arms 220 and the plurality of clamping devices 230 can achieve overall one-time clamping and positioning of the left and right sides, ensuring the position accuracy between the fender and the various mechanisms on the vehicle body and improving the clamping and positioning efficiency. In the process of clamping and positioning by the flip arms 220 and the plurality of clamping devices 230, under the action of the floating device 300, the flip arms 220 and the clamping devices 230 can float forward, backward, left and right, which is convenient for manual positioning operations.

[0063] The positioning device 120 can adopt the positioning device used for positioning in the prior art. The positioning device 120 preferably adopts the following multiple designs or a combination of multiple designs:

[0064] In some embodiments, the first frame 110 is located below the second frame 210 , so that the entire mechanism can be positioned on the vehicle body located therebelow by means of a plurality of positioning devices 120 on the second frame 210 .

[0065] In some embodiments, reference Figure 2The positioning device 120 includes two positioning pins 121, and the two positioning pins 121 are fixed at the bottom end of the first frame 110 at a preset distance along the left-right direction, and the length direction of the positioning pins 121 is the up-down direction.

[0066] In this embodiment, the distance between the two positioning pins 121 and the arrangement positions at the bottom end of the first frame 110 can be determined according to the actual situation of the positioning holes on the vehicle body that match with the two positioning pins 121.

[0067] When the floating positioning mechanism is positioned on the vehicle body using the positioning device 120, the floating positioning mechanism is moved above the vehicle body by the lifting device, and the floating positioning mechanism is manually fine-tuned so that the left and right positioning pins 121 are inserted into the two corresponding positioning holes on the vehicle body to limit the forward, backward, left and right movement of the vehicle body.

[0068] In some embodiments, reference Figure 2 The positioning device 120 includes two positioning columns 122 , which are fixed at the bottom end of the first frame 110 at a preset distance along the left-right direction, and the two positioning columns 122 are located on the outside of the two positioning pins 121 .

[0069] In this embodiment, the bottom end surface of the positioning column 122 can be a plane parallel to the first frame 110, or an inclined surface intersecting the first frame 110, or an arc surface convex downward or concave upward. The shape of the bottom end surface of the positioning column 122 is determined according to the abutment surface of the vehicle body against which it abuts.

[0070] When the floating positioning mechanism is positioned on the vehicle body by using the positioning device 120 , the bottom end surfaces of the left and right positioning posts 122 abut against the vehicle body, thereby restricting the vehicle body from moving upward.

[0071] In some embodiments, reference Figure 2 and Figure 3 The positioning device 120 includes a plurality of locking devices 123 , and the locking devices 123 include a movable block 1231 and a manual locking device 1232 .

[0072] The manual locking device 1232 is disposed at the bottom of the first frame 110 . The manual locking device 1232 has a positioning handle 1232 a . The movable portion of the manual locking device 1232 is connected to the movable block 1231 . The movable block 1231 is locked or unlocked by driving the positioning handle 1232 a .

[0073] In this embodiment, the movable block 1231 can be locked or unlocked manually by turning the position handle 1232a. When the floating positioning mechanism is positioned on the vehicle body by the positioning device 120, the top end surface of the movable block 1231 is abutted against the vehicle body by turning the position handle 1232a, thereby limiting the downward movement of the vehicle body from below.

[0076] In this embodiment, the purpose of six-point positioning is achieved through the cooperation design of the four locking devices 123 and the positioning pins 121.

[0077] In some embodiments, reference Figure 3 The locking device 123 further includes a positioning block 1233 , and the positioning block 1233 is fixed to the bottom end of the first frame 110 . When the movable block 1231 is locked by the manual locking device 1232 , the movable block 1231 is located below the positioning block 1233 .

[0078] In this embodiment, when the floating positioning mechanism is positioned on the vehicle body by using the positioning device 120, the abutting surface of the vehicle body is positioned between the movable block 1231 and the positioning block 1233. When there is a positioning hole on the vehicle body, the movable block 1231 can pass through the bottom of the positioning hole and abut against the positioning block 1233 to achieve a better positioning effect.

[0084] During specific implementation, a sliding limit groove can be preferably set on the second connecting rod 242 on the arm-turning connecting rod mechanism 240, and the length direction of the sliding limit groove is consistent with the length direction of the second connecting rod 242. One end of the second connecting plate 253 for clamping and positioning is connected to a sliding rod, which passes through the sliding limit groove and can slide in the sliding limit groove, and the end of the sliding rod is connected to a limiting nut.

[0085] In this embodiment, when the flip arm 220 flips, the flip arm connecting rod mechanism 240 also moves, driving the second clamping and positioning connecting plate 253 to slide up and down on the clamping and positioning slide rail 252. When the flip arm 220 flips from the outside to the inside, driving the second clamping and positioning connecting plate 253 to slide downward, a row of clamping positioning pins 254 are inserted into the positioning holes on the vehicle body to achieve the positioning function.

The lower limit plate 314 is located above the lower bull's eye bearing 313 and abuts against the universal ball of the lower bull's eye bearing 313.

[0107] The floating connecting plate 315 is preferably an inverted L-shaped structure. With the above design, on the one hand, the second frame 210 is restricted between the floating connecting plate 315 and the first frame 110, limiting the up and down movement of the second frame 210. On the other hand, under the action of the bull's eye bearing, the second frame 210 can make slight movements in the front, back, left and right directions relative to the first frame 110, so that when the mechanism clamping part 200 is used to clamp and position the fender and the vehicle body, there can be a certain amount of floating for fine adjustment of the position.

[0108] In some embodiments, there are four floating components 310 , and the four floating components 310 are respectively distributed around the first frame 110 and the second frame 210 .

[0109] In some embodiments, reference Fig.12 The floating device 300 further includes a plurality of limiting components 320 , and the limiting components 320 include a first limiting connecting plate 321 , a second limiting connecting plate 322 , and a spring plunger 323 .

[0110] The first position-limiting connection plate 321 is disposed on the first frame 110, and a first connection through hole is disposed on the first position-limiting connection plate 321. The second position-limiting connection plate 322 is disposed on the second frame 210, and a second connection through hole is disposed on the second position-limiting connection plate 322. The plug sleeve of the spring plunger 323 is disposed on one of the first connection through hole and the second connection through hole, and the pin of the spring plunger 323 is inserted into the other of the first connection through hole and the second connection through hole.

[0111] In this embodiment, the limiting assembly 320 can limit the floating range of the second frame 210 relative to the first frame 110 .

[0112] In some embodiments, a limiting assembly 320 is disposed on both sides of a floating assembly 310 .

[0113] In some embodiments, a row of first connecting through holes is provided on the first limiting connecting plate 321, and a row of second connecting through holes is provided on the second limiting connecting plate 322, so that the floating amplitude can be adjusted by adjusting the positional relationship between the spring plunger 323 and the first connecting through holes and the second connecting through holes according to actual conditions.

[0114] In some embodiments, reference Figure 1 and Figure 4 The floating positioning mechanism further includes at least two gap positioning parts 400, and the at least two gap positioning parts 400 are respectively arranged on the left and right flip arms 220 along the left and right directions.

[0115] Reference Fig.13 The gap positioning portion 400 has a positioning plug 410, and the positioning plug 410 faces inward. When the flip arm 220 flips inward, the positioning plug 410 is inserted into the gap between the vehicle door and the fender.

[0116] In this embodiment, the gap positioning portion 400 is used to determine that the gap between the vehicle door and the fender is within a precise range, that is, the thickness of the positioning plug 410 is the gap value between the two.

[0117] In some embodiments, reference Fig.13The gap positioning portion 400 also has a positioning connection block 420 , a positioning connection shaft 430 , a positioning connection pin, and a plug-in handle 440 .

[0118] The positioning connection block 420 is arranged on the flip arm 220, and a positioning connection through hole is arranged on the positioning connection block 420, and a positioning pin hole 421 is arranged on the positioning connection block 420, which is arranged in the vertical direction, and the positioning pin hole 421 is connected to the positioning connection through hole. The positioning connection shaft 430 is plugged into the positioning connection through hole and both ends extend out of the positioning connection through hole. The inner end of the positioning connection shaft 430 is connected to the positioning plug 410, and the outer end of the positioning connection shaft 430 is connected to the plug handle 440. The positioning connection shaft 430 is provided with a plug-in limit hole that runs through the vertical direction. The positioning connection pin can pass through the positioning pin hole 421 and the plug-in limit hole in sequence.

[0119] In this embodiment, the positioning connecting shaft 430 is driven to perform telescopic movement by the plug-in handle 440, and the positioning plug block 410 is driven to perform telescopic movement. When the positioning plug block 410 is needed to be plugged into the gap between the vehicle door and the fender, the positioning plug block 410 is driven to extend inward. The setting of the positioning connecting pin, the positioning pin hole 421 and the plug-in limit hole can realize the limitation of the insertion depth, so that the telescopic distance of the positioning connecting shaft 430 is not greater than the length of the plug-in limit hole.

[0120] In some embodiments, the positioning connection shaft 430 can be inserted into the positioning connection through hole through a shaft sleeve.

[0121] In some embodiments, a gap limiting groove is circumferentially arranged on the positioning connection shaft 430 .

[0122] Reference Fig.13 The gap positioning portion 400 also has a limiting bolt 450, one end of the limiting bolt 450 passes through the positioning connection block 420 and is inserted into the gap limiting groove, the limiting bolt 450 is threadedly connected to the positioning connection block 420, and the other end of the limiting bolt 450 extends out of the positioning connection block 420.

[0123] The positioning connecting shaft 430 is further positioned by screwing the limiting bolt 450 into the positioning connecting block 420 and abutting against the gap limiting groove, thereby preventing the positioning plug 410 from shaking in the gap between the vehicle door and the fender, thereby ensuring the accuracy of the gap between the vehicle door and the fender.

[0124] In some embodiments, there are four gap positioning portions 400 , two on the left side and two on the right side, and the two gap positioning portions 400 on each side are distributed along the up-and-down direction.

[0125] In some embodiments, reference Figure 1 , Figure 2 and Fig.14The floating positioning mechanism also includes a gap clamping portion 500, and the gap clamping portion 500 includes a front-rear moving device 510, a gap connecting shaft 520, a clamping spring 530 and a limiting nut 540.

[0126] The front-to-back moving device 510 is disposed on the first frame 110, and the front-to-back moving device 510 has a front-to-back moving end that can move in the front-to-back direction. The front-to-back moving end is connected to a gap connecting shaft 520, which is inserted into and passes through the second frame 210, and one end of the gap connecting shaft 520 is threadedly connected to a limit nut 540. A clamping spring 530 is sleeved outside the gap connecting shaft 520, and the clamping spring 530 is located between the second frame 210 and the limit nut.

[0127] In this embodiment, the clamping force of the clamping spring 530 can be adjusted by the extension range of the front-to-back moving end of the front-to-back moving device 510. When in use, since the positioning of the floating positioning mechanism is mainly achieved manually, especially when the positioning plug 410 of the gap positioning part 400 is inserted into the gap between the door and the fender, the second frame 210 needs to have a certain floating space, and after the plugging is completed, the position of the positioning plug 410 must be guaranteed to be stable. Therefore, when the positioning plug 410 is manually plugged, in order to ensure the smooth plugging process and stability after plugging, the gap clamping part 500 is added in this embodiment. Through the interaction force between the front-to-back moving device 510 of the gap clamping part 500 and the clamping spring 530, it is ensured that the pulling force of the front-to-back moving device 510 on the second frame 210 will not be too large to damage the vehicle parts, and the clamping effect of the positioning plug 410 can be achieved.

[0128] In some embodiments, the gap connecting shaft 520 is plug-connected to the second frame 210 via a shaft sleeve 550 , so that the gap connecting shaft 520 can move forward and backward on the second frame 210 .

[0129] In some embodiments, the forward and backward moving device 510 uses a cylinder, the piston rod of the cylinder is axially in the forward and backward direction, and the piston rod is the forward and backward moving end.

[0130] When the piston rod of the cylinder is connected to the gap by the connecting shaft 520, a connecting joint can be used to achieve the connection.

[0131] The utility model is described in detail above in conjunction with the embodiments of the drawings. A person skilled in the art can make various variations of the utility model according to the above description. Therefore, some details in the embodiments should not constitute a limitation of the utility model, and the utility model shall be protected within the scope defined by the attached claims.
