[0002] In the field of commercial vehicle manufacturing, the market demand for cargo fence models is increasing, and there are many types of cargo fence models. As the most used component on the cargo box of cargo fence vehicles, flower fences are assembled the most. The welding efficiency, welding quality, and welding size of the flower fences directly affect the delivery time of the entire cargo box. Among them, the car body flower fence positioning welding fixture is an important tool for fixing and positioning the car body flower fence during the automobile welding process.

[0003] After searching, the Chinese patent publication number CN210334947U disclosed "a clamping tool for flower fence welding including: a tool base for supporting the flower fence; a corrugated board pressure rod for extending along the length direction of the corrugated board to press the corrugated board; a swing rod hinged on the tool base and connected to the corrugated board pressure rod to drive the corrugated board pressure rod to move, and the extension direction of the hinge axis of the swing rod is the same as the extension direction of the corrugated board pressure rod; a pressure mechanism for applying pressure to the swing rod so that the corrugated board pressure rod presses the corrugated board."

[0004] This patented fixture is mainly used for positioning and fixing flower fences of a single size, and when welding flower fences of other sizes, the corresponding fixture is generally replaced for fixing. Among them, when welding the bolt plate of the flower fence, the bolt plate needs to be fixed to ensure that the bolt plate can be stably welded on the frame of the flower fence. However, since the bolt plates of different sizes required for welding flower fences will also be different, the bolt plate fixture of the corresponding size needs to be replaced. The replacement process is time-consuming and labor-intensive, and the operation efficiency is low. In view of this, the utility model proposes a bolt plate control fixture for servo-controlled flower fence welding. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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.

[0020] like Figures 1 to 4As shown, this embodiment proposes a servo-controlled bolt plate control fixture for flower fence welding, including a mounting plate 1, which is slidably connected to one end of a main frame 4, and a length control unit 3 is provided at the bottom end of the mounting plate 1 for driving the mounting plate 1 to move along the length direction of the main frame 4, and a bolt plate positioning mechanism 2 is provided on the top of the mounting plate 1, and the bolt plate positioning mechanism 2 includes two parallel slide rails 22, and the two slide rails 22 are both arranged parallel to the mounting plate 1, and the length of the two slide rails 22 is smaller than the length of the mounting plate 1, and the two slide rails 22 are fixedly connected to the top of the mounting plate 1, and both ends of the two slide rails 22 are slidably connected with sliders 23, and the top ends of the two sliders 23 at the same end are provided with bolt plate clamping members 24 for clamping the flower fence bolt plate by cooperating with the sliding of the slider 23, and a driving member 25 is provided on the mounting plate 1 for driving the two sliders 23 on the slide rails 22 to slide toward or away from each other.

[0021] The length control unit 3 drives the mounting plate 1 to move along the length direction of the main frame 4 and to the welding position of the flower fence bolt plate, and then the driving member 25 drives the two sliders 23 to slide toward or away from each other, thereby adjusting the spacing between the two sliders 23, so that the two sliders 23 move to the two ends of the flower fence bolt plate, and then the bolt plate clamping member 24 is controlled to clamp the flower fence bolt plate, so that the flower fence bolt plate is stably pressed onto the frame of the flower fence, which makes it convenient to accurately weld the flower fence bolt plate to the frame of the flower fence. The whole process can realize the rapid positioning of flower fence bolt plates of different sizes according to flower fences of different sizes. The operation is simple, which greatly improves the working efficiency.

[0022] Furthermore, the bolt plate clamping member 24 includes a lower clamping seat 241, which is fixedly connected to the top of the corresponding slider 23. One end of the top of the lower clamping seat 241 is fixedly connected to a cylinder 242, and the output end of the cylinder 242 is fixedly connected to a connecting plate 243. One end of the connecting plate 243 is fixedly connected to a pressure rod 244, and the bottom end of the pressure rod 244 is fixedly connected to an upper clamping seat 245. The upper clamping seat 245 is arranged parallel to the lower clamping seat 241, and the length of the upper clamping seat 245 is smaller than the length of the lower clamping seat 241. By controlling the cylinder 242 to move the connecting plate 243 downward, the pressure rod 244 drives the upper clamping seat 245 downward, causing the upper clamping seat 245 to contact and press the flower fence bolt plate, so that the flower fence bolt plate is stably installed on the flower fence frame, thereby facilitating the welding of the flower fence bolt plate.

[0023] Furthermore, the driving member 25 includes two reduction servo motors 251, which are respectively fixedly mounted at both ends of the mounting plate 1. The output shafts of the two reduction servo motors 251 are fixedly connected with screw rods 252. The middle part of the mounting plate 1 is fixedly connected with two parallel fixed seats 254. The two screw rods 252 are rotatably connected to the corresponding fixed seats 254 at one end away from the corresponding reduction servo motor 251. The bottoms of the two lower clamping seats 241 are fixedly connected with screw nuts 253. The two screw nuts 253 are respectively threadedly connected to the two screw rods 252. The screw spiral directions of the two screw rods 252 are opposite, and the two screw nuts 253 are symmetrically distributed along the center line of the mounting plate 1.

[0024] Working principle: First, place the frame of the flower fence on the lower clamping seat 241, and then drive the mounting plate 1 to move along the length direction of the main frame 4 and move to the welding position of the flower fence bolt plate through the length control unit 3, and then start the two reduction servo motors 251 to make the two screw rods 252 rotate synchronously. Since the screw threads of the two screw rods 252 have opposite directions, the two screw nuts 253 drive the two lower clamping seats 241 to move toward or away from each other, so that the lower clamping seat 241 can move to the two ends of the flower fence bolt plate, and then control the cylinder 242 to make the connecting plate 243 move downward, which makes the pressure rod 244 drive the upper clamping seat 245 to move downward, so that the upper clamping seat 245 conflicts with the flower fence bolt plate and presses it, so that the flower fence bolt plate is stably installed on the frame of the flower fence, thereby facilitating the welding of the flower fence bolt plate.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
