[0004] The objective of this invention is achieved through the following technical solution:

[0005] A fixture tooling device for forming automotive parts includes a fixture carrier, a sliding box, a frame, and a clamping mechanism. The frame is mounted on the sliding box, and the clamping mechanism is located at the bottom of the frame and at the top of the frame. The clamping mechanism includes multiple clamping components, each of which includes a pull shaft, a support base, and a spring. The pull shaft is movably mounted in the support base by the spring support, and the lower end of the pull shaft extends out of the support base and is provided with a shaft cap placed in the sliding box. The fixture carrier includes multiple clamps, and each fixture carrier is sequentially arranged within the frame and between the clamping mechanism and the clamping plate. Parts are arranged between corresponding clamps of adjacent fixture carriers. Each clamp of the bottommost fixture carrier abuts against the upper end of the corresponding pull shaft in the clamping mechanism.

[0006] The clamping mechanism includes an upper mounting plate and a lower mounting plate fixed within the frame. Each clamping component is disposed between the upper mounting plate and the lower mounting plate. The upper end of the pull shaft is provided with a positioning shaft head that passes through the upper mounting plate, and the lower end of the pull shaft passes through the lower mounting plate and is provided with a shaft cap.

[0007] The pull shaft includes a shaft cap, a positioning shaft head, and a connecting shaft. An upper limit sleeve and a lower limit sleeve are fitted on the pull shaft. The positioning shaft head, the upper limit sleeve, and the upper end of the connecting shaft are fixedly connected. The lower limit sleeve is fitted on the connecting shaft. The lower end of the connecting shaft extends into the sliding box and is fixedly connected to the shaft cap. A first limiting flange is fitted on the upper limit sleeve, and a second limiting flange is fitted on the lower limit sleeve. A spring is located between the first limiting flange and the second limiting flange. Adjusting shims are provided between the upper end of the spring and the first limiting flange, and between the lower end of the spring and the second limiting flange.

[0008] The upper limit sleeve has an internal intermediate plate, and the positioning shaft head, intermediate plate and connecting shaft are fixedly connected.

[0009] The support base has two upper limit plates on its upper side and two lower limit plates on its lower side. The positioning shaft head passes between the two upper limit plates, and the lower end of the connecting shaft passes between the two lower limit plates. The upper limit sleeve and the lower limit sleeve are disposed between the upper limit plate and the lower limit plate.

[0010] The support base includes two support side plates and an upper mounting block and a lower mounting block disposed between the two support side plates. The clamping mechanism includes an upper mounting plate and a lower mounting plate fixed within the frame. The upper mounting block is fixedly connected to the upper mounting plate, and the lower mounting block is fixedly connected to the lower mounting plate. An opening is provided in the middle of the support side plate, and the upper side of the opening forms the upper limit plate, and the lower side forms the lower limit plate.

[0011] The pull shaft in the clamping mechanism is driven to move by a pulling mechanism, which includes jaws and a cylinder that drives the jaws to move up and down. When the towing box moves to a designated position along the transmission line, the jaws enter the towing box, and the shaft caps at the lower ends of each pull shaft move into the jaws.

[0012] The towing box includes two side frames, and the upper end of the pulling mechanism enters the towing box through the gap between the two side frames. Positioning pin sleeves are provided on both side frames.

[0013] The frame has guide slides on both sides inside. The clamp carrier has a first end block at one end and a second end block at the other end.

The fixture carrier is accurately positioned to ensure product quality. At the same time, the fixtures can be replaced according to the product model, which meets the requirements of compatible production of automated production lines.

[0017] 2. This invention utilizes the combined action of a clamping mechanism and a sliding pressure plate to fix the fixture carrier and parts. Furthermore, the clamping mechanism can adjust the spring force by adjusting different numbers of adjusting shims as needed, thereby adjusting the clamping force of the clamping mechanism and improving the product qualification rate.

[0018] 3. In this invention, when placing the fixture carrier and parts, the pull shaft in the clamping mechanism is driven to descend by a pulling mechanism. After the operator pulls out the insertion plate, the fixture carrier and parts can be placed into the frame. After placement, the insertion plate is reinserted, and the pulling mechanism releases the pull shaft, so that each pull shaft of the clamping mechanism automatically cooperates with the insertion plate under the action of the spring to fix the fixture carrier and parts. The whole operation is simple and convenient. Attached Figure Description

Detailed Implementation

[0028] The invention will now be described in further detail with reference to the accompanying drawings.

[0029] like Figures 1-8 As shown, the present invention includes a clamp carrier 1, a sliding box 2, a frame 3, and a clamping mechanism 5, wherein as... Figure 1 As shown, the frame 3 is mounted on the towing box 2, and the frame 3 has a pressing mechanism 5 at its bottom and a pull-out pressure plate 304 at its top. Figures 5-7 As shown, the clamping mechanism 5 includes multiple clamping components, each including a pull shaft 501, a support base 505, and a spring 502. The pull shaft 501 is vertically and flexibly mounted in the support base 505, supported by the spring 502. The lower end of the pull shaft 501 extends out of the support base 505 and is provided with a shaft cap 5011, which is placed in the sliding box 2. Figure 2 As shown, the clamp carrier 1 includes multiple clamps 103, such as... Figure 1 As shown, each clamp carrier 1 is arranged in the frame 3 from low to high and is located between the clamping mechanism 5 and the insertion and removal pressure plate 304. Parts are provided between the corresponding clamps 103 of adjacent clamp carriers 1. Each clamp 103 of the bottom clamp carrier 1 abuts against the upper end of the corresponding pull shaft 501 in the clamping mechanism 5. The pull shaft 501 provides clamping force through the spring 502 and cooperates with the insertion and removal pressure plate 304 to achieve clamping and fixing of each clamp carrier 1 and part.

[0030] like Figure 5As shown, the clamping mechanism 5 includes an upper mounting plate 504 and a lower mounting plate 503 fixed within the frame 3. Each clamping component is disposed between the upper mounting plate 504 and the lower mounting plate 503. The upper end of the pull shaft 501 is provided with a positioning shaft head 5012 that passes through the upper mounting plate 504, and the positioning shaft head 5012 abuts against the corresponding clamp 103 in the lowest clamp carrier 1. The lower end of the pull shaft 501 passes through the lower mounting plate 503 and is provided with a shaft cap 5011 placed in the drag box 2.

[0031] like Figure 7 As shown, the pull shaft 501 includes a shaft cap 5011, a positioning shaft head 5012, and a connecting shaft 5013. An upper limit sleeve 506 and a lower limit sleeve 508 are fitted onto the pull shaft 501. The lower end of the positioning shaft head 5012, the upper limit sleeve 506, and the upper end of the connecting shaft 5013 are fixedly connected by double-ended screws. The lower limit sleeve 508 is fitted onto the connecting shaft 5013. The lower end of the connecting shaft 5013 passes through the support base 505 and extends into the drag box 2, where it is fixedly connected to the shaft cap 5011 by screws. The upper limit sleeve 506 is provided with a first limiting flange 5061, and the lower limit sleeve 508 is provided with a second limiting flange 5081. The spring 502 is disposed between the first limiting flange 5061 and the second limiting flange 5081. Adjusting shims 507 can be provided as needed between the upper end of the spring 502 and the first limiting flange 5061, and between the lower end of the spring 502 and the second limiting flange 5081, to adjust the elastic force of the spring 502, thereby adjusting the clamping force of the clamping mechanism 5. The pull shaft 501 structure of the present invention allows for easy adjustment of the number of adjusting shims 507. For example, by screwing the positioning shaft head 5012 and the connecting shaft 5013 apart, the spring 502 can be compressed and the adjusting shims 507 can be fitted onto the upper limit sleeve 506 or the lower limit sleeve 508.

[0032] like Figure 7 As shown, the upper limit sleeve 506 has an internal intermediate plate 5062, and the lower end of the positioning shaft head 5012, the intermediate plate 5062 and the upper end of the connecting shaft 5013 are fixedly connected.

[0033] like Figure 6 As shown, the support base 505 has two upper limit plates 5054 on its upper side and two lower limit plates 5055 on its lower side. The positioning shaft head 5012 passes between the two upper limit plates 5054, and the lower end of the connecting shaft 5013 passes between the two lower limit plates 5055. The upper limit sleeve 506 and the lower limit sleeve 508 are located between the upper limit plate 5054 and the lower limit plate 5055. The upper limit sleeve 506 limits displacement by abutting against the upper limit plate 5054, and the lower limit sleeve 508 limits displacement by abutting against the lower limit plate 5055.

[0034] like Figure 6 As shown, the support base 505 includes two support side plates 5053 and an upper mounting block 5052 and a lower mounting block 5051 disposed between the two support side plates 5053. The upper mounting block 5052 is fixedly connected to the upper mounting plate 504, and the lower mounting block 5051 is fixedly connected to the lower mounting plate 503. The support side plate 5053 has an opening in the middle, and the upper limit plate 5054 is formed on the upper side of the opening and the lower limit plate 5055 is formed on the lower side.

[0035] like Figure 8 As shown, the pull shaft 501 in the clamping mechanism 5 is driven to descend by a pulling mechanism to place each clamp carrier 1 and part. In this embodiment, the pulling mechanism includes jaws 6 and a cylinder 7 that drives the jaws 6 to move up and down. When the sliding box 2 moves to the designated position along the transmission line 8, the jaws 6 move into the sliding box 2, and the shaft caps 5011 at the lower end of each pull shaft 501 move into the jaws 6. When the sliding box 2 stops moving, the cylinder 7 starts to drive the jaws 6 to move down. The jaws 6 drive each pull shaft 501 to move down so that the positioning shaft head 5012 is lower than the upper mounting plate 504. Then, the operator pulls out the insertion and removal plate 304 to expose the upper opening of the frame 3, and places each clamp carrier 1 and part into the frame 3 in sequence. After placement, the operator reinserts the insertion and removal plate 304, and then the cylinder 7 starts to return to its original position. Each pull shaft 501 is lifted up by the spring 502 and cooperates with the insertion and removal plate 304 to clamp each clamp carrier 1.

[0036] like Figures 3-4 As shown, guide slides 305 are provided on both sides inside the frame 3, such as... Figure 2 As shown, the fixture carrier 1 has a first end block 101 at one end and a second end block 102 at the other end. Both the first end block 101 and the second end block 102 have sliding grooves that cooperate with the corresponding guide slides 305 to provide guidance, thus ensuring that each fixture carrier 1 is placed vertically. Both the first end block 101 and the second end block 102 have fixture positioning pins 104 to ensure accurate positioning when the fixture carrier 1 is stacked. Additionally, the end of the fixture carrier 1 has a part positioning block 105 and a limiting groove 106 to ensure the part positioning reference, thereby improving the part forming accuracy. The fixtures 103 in the fixture carrier 1 are sequentially spliced ​​in a line. The structure of the fixture 103 is a known technology in the art, and the present invention allows for the replacement of corresponding fixtures 103 according to different product models, thereby meeting the requirements of compatible production lines.

[0037] like Figures 3-4As shown, the frame 3 has inner side plates 302 on both sides inside, and the guide slides 305 are respectively installed on the corresponding inner side plates 302. The upper end of the frame 3 has a slot 301 for the insertion and removal pressure plate 304 to pass through. In addition, the lower ends of both sides of the frame 3 are provided with flexible material blocks 303 to buffer and reduce noise during production.

[0038] like Figure 3 As shown, a barcode component 4 is provided on one side of the frame 3. The barcode component 4 includes a barcode frame 401 and a two-dimensional barcode 402 disposed on the barcode frame 401. The two-dimensional barcode 402 can be designed and manufactured according to actual needs for subsequent production information exchange.

[0039] like Figure 1 As shown, the trailer box 2 includes box frames 201 on both sides, as... Figure 8 As shown, the upper end of the pulling mechanism enters the sliding box 2 through the gap between the two side box frames 201. Both side box frames 201 are provided with positioning pin sleeves 202. In order to realize the positioning of the present invention on the transmission line 8, in this embodiment, the transmission line 8 is provided with positioning pins that are driven to rise and fall by a cylinder. After inserting into the positioning pin sleeves 202, the positioning of the present invention is realized.

[0040] The working principle of this invention is as follows:

[0041] During operation, the invention is driven by a robotic arm or other mechanism to slide along the transmission line 8, wherein, for example... Figure 8 As shown, the sliding box 2 slides along the transmission line 8. When it moves to the workstation where the part is placed, the upper jaw 6 of the pulling mechanism at that workstation moves into the sliding box 2, and the shaft caps 5011 at the lower ends of each pull shaft 501 in the clamping mechanism 5 move into the jaw 6. Then the pulling mechanism drives the jaw 6 to move down, thereby causing each pull shaft 501 to move down and making the positioning shaft head 5012 lower than the upper mounting plate 504. Then the operator pulls out the insertion and removal plate 304 to expose the upper opening of the frame 3, and places each clamp carrier 1 and part into the frame 3 in sequence. After placement, the operator reinserts the insertion and removal plate 304, and then the cylinder 7 starts to return to its original position. Each pull shaft 501 is lifted up by the spring 502 and cooperates with the insertion and removal plate 304 to clamp each clamp carrier 1. The sliding box 2 can then move along the transmission line 8 to the next workstation.

[0042] The clamping force of the clamping mechanism 5 of the present invention can be adjusted as needed. Different numbers of adjusting shims 507 can be set between the two ends of the spring 502 and the corresponding limiting sleeve flange to adjust the elastic force of the spring 502, thereby adjusting the clamping force of the clamping mechanism 5. In addition, while ensuring accurate positioning of parts and improving product qualification rate, the fixture carrier 1 of the present invention can also replace the corresponding fixture 103 according to different product models, thereby meeting the requirements of compatible production of automated production lines.
