Description

Technical Field

[0001] The utility model belongs to the technical field of automobile manufacturing tools, and particularly relates to a jig used for automobile painting. Background Art

[0002] A car body painting jig refers to a tool that uses the holes, slots, and platforms of the car body for mounting and support during the painting process to control the opening and closing amount of each car cover. During the painting process, the car body requires a set of jigs with a certain strength and a certain three-dimensional spatial dimensional accuracy to strictly ensure the opening and closing amount of the car's front trunk lid to avoid contact scratches; ensure the high efficiency of loading and unloading and the safety of the operation process, ensure that the robot is provided with a convenient and flexible moving space during the sliding spraying and manual spraying process, and achieve uniformity in spraying the car body surface, including the internal and external curved surfaces.

[0003] In the existing technology, such automobile painting jigs are still largely at the primitive stage of using one or several support rods to support the front and rear trunk lids. On the automobile trunk lid painting assembly line, there are nearly ten engineering stations that need to open and close the front trunk lid, which generally weighs more than 8-20kg. The production cycle of the assembly line is generally 50 to 80 seconds. Such high-frequency and repeated opening and closing of the front trunk lid is very physically demanding, and long-term work will also lead to low operator efficiency. In addition, in the previous automobile trunk lid support jig style, the control of the trunk lid opening is single and the precision is difficult to control. Utility Model Content

The embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] Example:

[0029] like Figure 1-4 As shown, this embodiment provides a jig for automobile painting, comprising a hood positioning and loading device 1, a crossbeam mounting and fixing device 2, and a connecting arm device 3;

[0030] The connecting arm device 3 includes a first support rod 301, a second support rod 302, a connecting rod 303 and an elastic component, one end of the first support rod 301 is hinged to the hood positioning and loading device 1, the other end of the first support rod 301 is hinged to one end of the second support rod 302, the other end of the second support rod 302 is hinged to the crossbeam mounting fixing device 2, one end of the connecting rod 303 is hinged to the first support rod 301, and the other end of the connecting rod 303 slides with the second support rod 302, the elastic component includes an elastic member 304 and an elastic adjusting member, one end of the elastic member 304 is connected to the first support rod 301, one end of the elastic adjusting member is connected to the connecting rod 303, and the elastic adjusting member is provided with an adjusting portion that can move relative to one end of the elastic adjusting member, and the adjusting portion is connected to the other end of the elastic member 304.

[0031] In the jig of this embodiment, the hood positioning and loading device 1 and the crossbeam mounting and fixing device 2 are fixed to the trunk lid and the vehicle body crossbeam, respectively. During the process of opening or closing the trunk lid, the hinged structure between the first support rod 301 and the second support rod 302 can realize the change of the relative positions of the hood positioning and loading device 1 and the crossbeam mounting and fixing device 2. At the same time, the provided connecting rod 303 and the elastic component structure ensure the stability of the first support rod 301 and the second support rod 302 during the relative rotation process, thereby ensuring the stability of the trunk lid closing process, preventing the trunk lid from closing too quickly, and protecting the vehicle body crossbeam from being easily bumped and damaged. The contraction elastic force of the elastic member 304 in the elastic component can also be adjusted according to the model and weight of each trunk lid. When the operator lifts the hood positioning and loading device 1 upward, a lever effect is generated between the first support rod 301, the second support rod 302, and the connecting rod 303. The contraction elastic force of the elastic member 304 can reduce the impact of the weight of the trunk lid, thereby achieving a labor-saving effect.

[0032] In this embodiment, a slide member 305 is provided on the second support rod 302 , and the slide direction of the slide member 305 is set along the length extension direction of the second support rod 302 , and the other end of the connecting rod 303 is slidably matched with the slide of the slide member 305 .

[0033] The structure of the slide member 305 provided above allows the movement trajectories of the first support rod 301, the second support rod 302, and the connecting rod 303 to be controlled within the same axis when the entire fixture is opened and closed in an actual environment. This eliminates the problem of inaccurate trunk lid opening caused by displacement of the elastic member 304 during telescopic movement, and the problem of affecting the opening accuracy when multiple device components are coordinated. This can improve the yield rate and operating efficiency of trunk lid spraying in actual use.

[0034] The elastic member 304 of this embodiment is a tension coil spring member, and the elastic adjustment member includes a first hook member 306, a second hook member 307 and an adjustment seat 308. The first hook member 306 is connected to the connecting rod 303, the adjustment seat 308 is threadedly engaged with the first hook member 306, and the second hook member 307 is connected to the adjustment seat 308 to form the adjustment part of the elastic adjustment member.

[0035] In the above structure, when the operator uses the weight of the vehicle trunk lid to manually pull it closed, the tension coil spring member is pulled up, thereby slowing down the closing speed of the trunk lid, which is beneficial to protecting the vehicle body crossbeam from being easily bumped and damaged. At the same time, the relative distance between the adjustment seat 308 and the first hook member 306 is adjusted to adjust the contraction elastic force of the tension coil spring member to meet different usage requirements.

[0036] In this embodiment, one end of the first support rod 301 is further provided with a third support rod 309 hingedly connected to the cover positioning and loading device 1;

[0037] A first locking device is provided at one end of the first support rod 301, and the first locking device includes a locking seat 310, a locking rod 311 and a blocking rod 312. The locking seat 310 has a locking groove for hingedly connecting the third support rod 309, the locking rod 311 is hingedly provided on one side of the locking groove, and the blocking rod 312 is provided on the other side of the locking groove.

[0038] In the above structure, the third support rod 309 is provided to extend the overall length to adapt to different models of trunk lids. When it is needed to use, the third support rod 309 needs to be rotated and the third support rod 309 needs to be matched with the lock slot, and then the lock rod 311 needs to be rotated to make it abut against the blocking rod 312, so that the third support rod 309 is relatively fixed in the lock seat 310. When it needs to be stored, the lock rod 311 and the blocking rod 312 are removed from the abutting state, and the angle of the third support rod 309 relative to the first support rod 301 is adjusted to fold it, thereby reducing the overall size of the occupied area and facilitating storage and organization.

[0039] In this embodiment, a support opening fixing rod 313 is also hingedly provided on the second support rod 302, and a fixing seat 314 is provided at one end of the support opening fixing rod 313. A U-shaped hook 315 is provided on the first support rod 301, and a fixing groove that can cooperate with the U-shaped hook 315 is provided on the fixing seat 314.

[0040] In the above structure, by rotating the support opening fixing rod 313, the fixing groove of the fixing seat 314 is matched with the U-shaped hook part 315, so as to limit and fix the relative angle between the first support rod 301 and the second support rod 302, thereby controlling the opening of the trunk lid to meet different usage requirements.

[0041] The hood positioning and loading device 1 of this embodiment includes a hood positioning and loading base body 101, a handle safety lock device, and an operating handle member 102. The hood positioning and loading base body 101 is provided with a hood positioning column 103. The handle safety lock device includes a safety lock base 104, a safety lock rod 105 and a safety lock spring member 106. The safety lock rod 105 is slidably engaged with the safety lock base 104. The safety lock spring member 106 is sleeved on the safety lock rod 105 and is located in the safety lock base 104. One end of the operating handle member 102 is hinged to the hood positioning and loading base body 101, and a mating member that can cooperate with the safety lock rod 105 is provided at one end of the operating handle member 102.

[0042] At the same time, the beam mounting and fixing device 2 of this embodiment includes a beam mounting and fixing seat 201 and a second locking device, and the second locking device includes a U-shaped locking member 202, a latch member 203 and a rotating blocking rod 204.

[0043] In summary, the advantages of the present invention are:

[0044] 1. The hinged structure between the first support rod 301 and the second support rod 302 of the present application can realize the change of the relative positions of the hood positioning and loading device 1 and the crossbeam mounting and fixing device 2. At the same time, the connecting rod 303 and the elastic component structure are provided to ensure the stability of the first support rod 301 and the second support rod 302 during the relative rotation process, thereby ensuring the stability of the trunk lid closing process, preventing the trunk lid from closing too quickly, and helping to protect the vehicle body crossbeam from being easily bumped and damaged. The contraction force of the elastic member 304 in the elastic component can also be adjusted according to the model and weight of each trunk lid. When the operator lifts the hood positioning and loading device 1 upward, a lever effect is generated between the first support rod 301, the second support rod 302, and the connecting rod 303. Combined with the contraction force of the elastic member 304, the impact of the weight of the trunk lid can be reduced, thereby achieving a labor-saving effect.

[0045] 2. The structure of the slide member 305 of the present application allows the movement trajectories of the first support rod 301, the second support rod 302, and the connecting rod 303 to be controlled within the same axis when the entire fixture is opened and closed in an actual environment. This eliminates the problem of inaccurate trunk lid opening caused by displacement of the elastic member 304 during telescopic movement, and the problem of affecting the opening accuracy when multiple device components are coordinated. This can improve the yield rate and operating efficiency of trunk lid spraying in actual use.

[0046] 3. The support opening fixing rod 313 provided in this solution can meet the opening requirements of the trunk lid of different vehicle bodies, realizing the multi-purpose function of one body, and is provided with a safety lock mechanism at the connection with the vehicle body. The fixture is safer after installation, and it is not easy for the fixture to fall off and cause the trunk lid to hit the human head accidentally.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
