[0020] like Figure 1-5 As shown, the utility model provides an eccentric shaft clamping device for an oblique scrap shear, comprising a shear frame 4, a shearing head 6, an eccentric shaft 1, and a clamping block 2. The shear frame 4 is provided with the shearing head 6 inside, and a driving device 3 is provided above the shear frame 4. The output end of the driving device 3 is fixedly connected to the shearing head and is used to drive the shearing head 6 to move up and down. The eccentric shaft 1 passes through the side of the shear frame 4 and is connected to the clamping block 2. The eccentric shaft 1 is used to adjust the position of the clamping block 2 by rotating so that the clamping block 2 is close to the shear head 6. In this application, the driving mechanism 3 is a shearing cylinder, which passes through the top plate and is fixedly connected to the shearing head.

[0021] like Figure 1-3 As shown, the shearing machine frame 4 includes two side panels, a top panel, and a rear side panel that are arranged parallel to each other. The top panel is arranged on top of the two side panels and is used to connect the side panels to form a movable space for accommodating the shearing head 6. Two first slide rails corresponding to each clamping block are arranged in the vertical direction on the rear side panel. A corresponding slide rail space is formed between each first slide rail and the clamping block 2. The shearing head 6 moves up and down along the slide rail space under the action of the drive mechanism. The clamping block is arranged inside the shearing machine frame 4. There are two clamping blocks. The clamping block 2 is a rectangular block arranged in the vertical direction. The upper and lower ends of the rectangular block are provided with eccentric grooves for the eccentric shaft to pass through. Each clamping block is arranged close to the corresponding side panel of the shearing machine frame 4. It should be noted that the lower end face of the shearing machine frame 4 is an inclined surface. The side close to the rear side panel is relatively high. The outer end of each eccentric shaft 1 is fixedly connected to the pressure plate 5 by a number of pins.

[0022] It should be noted that each side panel of the shearing machine frame 4 is provided with a through hole for the eccentric shaft to pass through. In the present application, there are multiple through holes and four eccentric shafts, and two eccentric shafts are provided on each side of the shearing machine frame 4. The upper and lower ends of the rectangular block are provided with eccentric grooves for the eccentric shaft to pass through, which are divided into upper eccentric grooves and lower eccentric grooves. The corresponding eccentric shaft 1 passes through the upper eccentric groove and the lower eccentric groove connected to the clamping block 2 from the side panel of the shearing machine frame 4. By rotating the corresponding eccentric shaft 1, the clamping block 2 is adjusted to move toward the direction close to the shearing head, so that the clamping block 2 is close to the shearing head 6, which can effectively and conveniently clamp the shearing head 6 and make it run smoothly. The present application has a simple structure, but a clever design, which can greatly improve the overall working efficiency of the shearing machine and reduce processing costs. It is also easy to maintain and adjust, further improving its service life.

[0023] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these should also be considered within the scope of protection of the present invention.
