[0002] In the design of AGVs (Automated Guided Vehicles), the front chassis is one of the core components, directly affecting the vehicle's navigation accuracy, load-bearing capacity, and movement stability. The machining of the AGV front chassis requires processing its front, back, and sides. Typically, this is done in two stages using two fixtures: one stage processes the front and sides of the AGV front chassis, and the other stage processes the back.

[0003] The front of the AGV front chassis usually has many protruding parts, such as tire mounting brackets and sensor protective covers. When processing the back of the AGV front chassis, the front of the AGV front chassis needs to be placed face down. However, during the process of placing the AGV front chassis into the fixture, these protruding parts may collide with the parts on the fixture, causing damage to the AGV front chassis or the fixture.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below through embodiments and in conjunction with the accompanying drawings.

[0022] Example: This embodiment provides a machining fixture for the back of the AGV front chassis, such as... Figures 1 to 4 As shown, it includes a base plate 1, on which a lifting frame mechanism is provided, and a mounting column 2 is provided around the lifting frame mechanism. The mounting column is provided with a support and a clamping component. The lifting frame mechanism includes a lifting component and a lifting frame driven by the lifting component. The lifting frame includes a base plate 4, on which a limiting baffle 5 and a material slide rail 6 are provided. The material slide rail 6 is set below the limiting baffle 5.

[0023] Specifically, the substrate 4 is approximately H-shaped, with a cutout in the center for the mounting column to pass through. A crossbeam 10 is located in the center of the cutout. Mounting plates 11 extend outward from the first ends and center of both sides of the substrate 4. Limiting baffles 5 are mounted on the mounting plates. Material slide rails 6 are located on both sides of the substrate. The lifting assembly is connected to the four corners of the substrate and the crossbeam. The lifting assembly includes a power cylinder 12 and a guide column 13. The power cylinder 12 is centrally located and connected to the center of the crossbeam 10. The guide column 13 surrounds the power cylinder 12 and is connected to the four corners of the substrate. The material slide rail 6 includes a support plate and a slide rail. The support plate is vertically mounted on the substrate 4, and the slide rail is located at the upper end of the support plate. The distance between the slide rail and the substrate is greater than the height of the highest point of the front of the AGV chassis. In this embodiment, the material slide rail is lower than the support member when the lifting assembly is not raised. In addition, an anti-backward baffle 7 is provided on the base plate corresponding to the second end of the substrate 4. The anti-backward baffle 7 is flush with the limiting baffle 5 when the lifting mechanism is not raised.

[0024] Specifically, the support components include clamping support 8 and floating support 9. The clamping support 8 corresponds one-to-one with the clamping assembly, and the floating support 9 is mounted on the mounting post located in the hollowed-out area of ​​the substrate. The floating support is controlled by a hydraulic system. After the clamping assembly completes the clamping of the AGV front panel, the floating support rises to provide auxiliary support for the AGV front panel.

[0025] like Figure 5As shown, the clamping assembly 3 includes a hydraulic cylinder 34, a pressure block, and a rotating plate 33. The pressure block includes a connected pressure arm 31 and a drive plate 32. The pressure arm 31 is located on the upper side of the drive plate, and a pressing part extends downward from the end of the pressure arm. A rotating connection part is provided on the base of the hydraulic cylinder. The first end of the rotating plate 33 is rotatably mounted on the rotating connection part. The lower end of the drive plate 32, away from the pressure arm 31, is rotatably connected to the piston rod of the hydraulic cylinder 34. The lower end of the drive plate 32, near the pressure arm, is rotatably connected to the second end of the rotating plate 32.

[0026] In this embodiment, the AGV front chassis back processing fixture is used by first raising the lifting frame via the lifting assembly. Then, the AGV front chassis plate is pushed in along the material guide rail and abuts against the limiting baffle. At this time, due to the lifting frame being raised, the protruding parts on the front of the AGV front chassis plate will not collide with the parts on the fixture, thus protecting the AGV front chassis plate and the processing fixture. Afterward, the lifting assembly drives the lifting frame to fall. During the fall, the AGV front chassis first contacts the clamping support, providing support for the AGV front chassis. After the fall is complete, the material guide rail is located below the AGV front chassis and does not contact it, while the limiting baffle still abuts against the side of the AGV front chassis. In addition, the anti-reverse baffle on the chassis plate also abuts against the side of the AGV front chassis. The limiting baffle and the anti-reverse baffle work together to limit the movement of all sides of the AGV front chassis. Next, the clamping assembly clamps the AGV front chassis, and preferably, the hydraulic system controls the floating support to rise and provide auxiliary support for the AGV front chassis.
