An object of the utility model is to provide an anchor clamps based on target penetration experiment for when solving high-speed striking wood-plastic composite board, the impact force that wood-plastic composite board atress is inhomogeneous, wood-plastic composite board is fixed insecure, wood-plastic composite board received is too big.

In order to achieve the above purpose, the technical scheme of the utility model is that: a clamp for a targeted penetration experiment is characterized by consisting of a base, a fixed bracket, a movable bracket, a slide block, a locking piece, a mandril, a concave steel plate, a hydraulic device and a buffer strip, a fixed bracket is fixed at the right end of the base, a movable bracket is slidably arranged at the left end of the base, the movable bracket and the fixed bracket are both vertically and downwards placed, a sliding block is fixed at the lower part of the movable bracket, the slide block is connected with the base in a sliding way, the upper part of the slide block is provided with a locking piece, the upper parts of the fixed bracket and the movable bracket are respectively provided with a mandril, a concave steel plate is fixed at the action ends of the two ejector rods, a hydraulic device and a buffer strip are arranged on the concave steel plate, the action end of the hydraulic device is adjusted according to the thickness of the wood-plastic composite board, the buffer strip is arranged along the action surface of the concave steel plate, and meanwhile, the action end of the hydraulic device is also provided with the buffer strip. Further, the buffer strip is rectangular. Further, a handle is arranged at the driving end of the ejector rod.

The beneficial effects of the utility model reside in that: the utility model provides a pair of anchor clamps based on targeting penetration experiment encloses into the space that the compound board was moulded to the centre gripping wood through fixed bolster and movable support, through the fixed wood-plastic composite board of ejector pin centre gripping on fixed bolster and the movable support, the compound board is moulded to main fixed wood of its hydraulic means, and hydraulic means is adjusted according to the compound board thickness of wood-plastic. The arrangement of the buffer strips mainly aims to further increase the stability of the wood-plastic composite board and absorb the impact force on the wood-plastic composite board. The clamp is simple to operate, convenient to use and high in reliability, can fix the wood-plastic composite board, can absorb impact force applied to the wood-plastic composite board during high-speed impact, greatly improves the working efficiency of a targeted penetration experiment, and has high practical value.

Detailed Description

The structural features and technical implementation of the present invention will be described in detail below with reference to the accompanying drawings in combination with embodiments.

The utility model provides an anchor clamps based on target penetration experiment, at first base 1 is the metalwork of rectangle, and its effect is fixed other part, is fixed with a vertical fixed bolster 9 of putting on the upper portion of base 1 right-hand member, and fixed bolster 9 is the metalwork of rectangle, installs a ejector pin 4 on fixed bolster 9 upper portion, and ejector pin 4 is in the level and places, and it is the external screw thread at the pole portion of ejector pin 4. A concave steel plate 6 is fixed to the action end of the ram 4 between the fixed bracket 9 and the movable bracket 5, and as shown in fig. 1, a buffer strip 8 and a hydraulic device 7 are provided on the inner side of the action surface of the concave steel plate 6, and a buffer strip 8 is provided on the action end of the hydraulic device 7. The left end of the base 1 is provided with a movable support 5, the movable support 5 is matched with a fixed support 9 for use, and the movable support 5 and the fixed support 9 are both vertically arranged. The lower part of the movable bracket 5 is fixedly provided with a slide block 2, the base 1 of the movable bracket is in sliding connection with the slide block 2, and the distance between the movable bracket 5 and the fixed bracket 9 can be changed by moving the slide block. In order to realize the relative fixation between the movable support 5 and the base 1, the locking part 3 is arranged on the sliding block 2, the locking part 3 is a jackscrew, and the relative fixation between the movable support 5 and the base 1 can be realized after the locking part 3 is tightly jacked. A push rod 4 is mounted on the upper part of the movable support 5, a concave steel plate 6 is fixed at the action end of the push rod 4 between the fixed support 9 and the movable support 5, as shown in fig. 1, a buffer strip 8 and a hydraulic device 7 are arranged on the inner side of the action surface of the concave steel plate 6, and the buffer strip 8 is arranged at the action end of the hydraulic device 7.
