[0017] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will further describe the present application with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0018] In view of the problems of the prior art, the present application provides an automatic elastic clamping and taking material structure, which will be described in detail below with reference to the drawings.

[0019] Embodiment 1

[0020] Referring to Figs. 1-3As shown, the technical solution adopted in this specific embodiment is: an automatic elastic clamping and material handling structure, which is generally attached to a metal bar testing sample preparation device. It specifically includes a material handling cylinder 1, a piston rod 2, and a material receiving device 3. The material handling cylinder 1 is connected to and controlled by a hydraulic system through a hydraulic pipeline. The material receiving device 3 is installed at the telescopic end of the piston rod 2. The piston rod 2 is controlled by the hydraulic system to perform telescopic movement within the hydraulic cylinder 2, which drives the material receiving device 3 to telescopically extend and retract to achieve clamping / material handling of the bar.

[0021] It should be specifically noted that the receiving device 3 is a multi-lobed elastic clamping structure. Specifically, the receiving device 3 includes multi-lobed arc-shaped clamping pieces 31. The multi-lobed arc-shaped clamping pieces 31 enclose and form an elastic clamping space 311 for clamping / grabbing bar stock. During use, the size of the elastic clamping space 311 changes as the bar stock is clamped, and also varies depending on the size of the bar stock.

[0022] The arc-shaped clip 31 is an arc-shaped elastic clip, particularly an elastic metal arc-shaped clip, and at least two of them are provided.

[0023] It should be specifically noted that the receiving device 3 is fixed to the piston rod 2 via a detachable connection to facilitate maintenance and replacement. For example, the receiving device 3 can be threaded onto the piston rod 2, or it can be fixed to the piston rod 2 with screws. Of course, the receiving device 3 can also be connected to the piston rod 2 via other snap-fit ​​methods.

[0024] It should be specifically noted that L-shaped connectors 4 are fixedly connected to the left and right sides of the material taking cylinder 1, and are fixedly installed on the metal rod material testing sample preparation equipment through the L-shaped connectors 4.

[0025] Example 2

[0026] See Fig. 2 As shown, the difference between this embodiment and embodiment 1 is that the inner end of the arc-shaped clamp 31 away from the piston rod 2 has a certain curvature to facilitate the insertion of the bar.

[0027] The specific working principle is as follows: After one end of the workpiece is drilled and milled, the piston rod 2 in the pick-up cylinder 1 is controlled by the control system to extend into the notch of the workpiece, so that the receiving device 3 extends into the notch of the workpiece to clamp the required bar. After the bar is clamped, the equipment enters the next milling program to mill off the connection part between the other end of the bar and the blank. After the milling is completed, the piston rod 2 is controlled by the control system to withdraw from the workpiece. At this time, the bar will be clamped out by the receiving device 3.

[0028] In use, the universality of the device for different specifications of cylindrical rod materials can be considered, the rod material can be clamped during the sample preparation process, the drilling and milling process is more stable, the rod material can be taken out, secondary clamping and extraction are not needed, the labor cost and the risk of human accidents are avoided, the rod material preparation work is more efficient, low-consumption, safe and stable, and the practicality is high.

[0029] In the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more than two; The orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] The above description is only used to illustrate the technical scheme of the utility model and is not limited, and other modifications or equivalent replacements of the technical scheme of the utility model made by those skilled in the art should be covered in the scope of the claims of the utility model.
