DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] In view of the problems existing in the prior art, the present invention provides a universal fully automatic bar sample preparation device, which is described in detail below in conjunction with the accompanying drawings.

[0039] Example 1

[0040] See also Figure 1-Figure 11 As shown, the technical solution adopted in this specific embodiment is: a universal fully automatic bar sample preparation device, which specifically includes a frame 1, a blank clamping mechanism 2, a first driving mechanism 3 arranged on the frame 1 and used to drive the blank clamping mechanism 2 to move forward and backward, a CNC power milling mechanism 4 respectively arranged on the left and right sides of the frame 1, a second driving mechanism 5 for driving the power milling mechanism 4 to move left and right, and an elastic clamping and material taking mechanism 6 arranged on one side of the frame 1.

[0041] It should be specifically explained that the blank clamping mechanism 2 specifically includes a base 21, on which a clamping block 22 is fixedly mounted. There are multiple clamping blocks 22, and the multiple clamping blocks 22 are distributed in the moving direction of the blank clamping mechanism 2. Each of the clamping blocks 22 is provided with at least one fixed jaw 221, and the fixed jaw 221 is arranged on the front side or the rear side of the clamping block 22. A clamping cylinder 23 is arranged on the opposite side of the clamping block 22 located at the fixed jaw 221. The clamping cylinder 23 is fixed on the base 21, and a first piston rod 231 is arranged in the clamping cylinder 23. The end of the first piston rod 231 away from the clamping cylinder 23 extends toward the fixed jaw 221, and the fixed jaw 221 is a V-shaped groove with an opening toward the first piston rod 231. The setting of the V-shaped groove can match cylindrical blanks 24 of different sizes.

[0042] At least two first piston rods 231 should be provided on one clamping cylinder 23, and the two first piston rods 231 are located in the same horizontal plane. The two first piston rods 231 can respectively clamp the left and right sides of the same surface of the cylindrical blank 24 to improve the clamping stability.

[0043] The clamp block 22 can be a single-sided structure or a double-sided structure. When the clamp block 22 is a single-sided structure, only one side of it has a fixed jaw 221; when the clamp block 22 is a double-sided structure, fixed jaws 221 are respectively provided on both sides of the clamp block 22, and the two fixed jaws 221 are respectively provided on opposite sides of the clamp block 22.

[0044] It should be further explained that the elastic clamping and material picking mechanism 6 specifically includes a material picking cylinder 61, a second piston rod 62 and a material receiver 63. The material picking cylinder 61 is controlled by a control system (not shown in the figure), the second piston rod 62 is connected to the material picking cylinder 61, and the material receiver 63 is installed at the telescopic rod end of the second piston rod 62.

[0045] The material receiver 63 is composed of a plurality of arc-shaped clips 631 connected together, and the plurality of arc-shaped clips 631 enclose an elastic clamping space 6311 for clamping the rod material. During use, the size of the elastic clamping space 6311 changes with the clamping of the rod material, and varies with the size of the rod material.

[0046] The arc-shaped clip 631 is an arc-shaped elastic clip, in particular, an elastic metal arc-shaped clip, and at least two of them are provided.

[0047] The material catcher 63 is fixed to the second piston rod 62 in a detachable manner to facilitate the maintenance and replacement of the material catcher 63. For example, the material catcher 63 can be connected to the second piston rod 62 by threads, or the material catcher 63 is fixed to the second piston rod 62 by screws.

[0048] It should be specifically explained that the CNC power milling mechanism 4 includes a spindle box 41, a shaft 411 arranged in the spindle box 41, a tool 4111 fixedly connected to one end of the shaft 411 toward the blank clamping mechanism 2, and a motor 42 for driving the shaft 411 to rotate.

[0049] The tool 411 on the CNC power milling mechanism 4 located on one side of the frame 1 is a flat-head drill bit;

[0050] The tool 411 on the CNC power milling mechanism 4 located on the other side of the frame 1 is a hollow drill bit;

[0051] The elastic clamping and material taking mechanism 6 and the CNC power milling mechanism 4 whose cutter 411 is a hollow drill bit are arranged on the same side of the frame 1. The material receiving device 63 is arranged opposite to the flat head drill bit.

[0052] It should be specifically explained that both the first driving mechanism 3 and the second driving mechanism 5 are ball screw structures, and their specific composition is a well-known technology, so the specific structural composition of the two will not be repeated here.

[0053] Protective covers 11 may be provided on the front and rear sides of the frame 1 respectively.

[0054] During use, the cylindrical blank 24 is clamped by the blank clamping mechanism 2. After the first driving mechanism 3 drives the blank clamping mechanism 2 to move to the designated working position, the CNC power milling mechanism 4 is started to drill and mill the workpiece. After the drilling and milling work is completed, the CNC power drilling and milling mechanism 4 is driven by the second driving mechanism 5 to withdraw the workpiece, and then the first driving mechanism 3 continues to drive the blank clamping mechanism 2 to move forward to the elastic clamping and material taking mechanism 6, and the rod obtained by drilling and milling is clamped by the material receiver 63. After clamping, the other side of the workpiece is milled by the CNC power milling mechanism 4 on the opposite side of the material receiver 63. After the milling work is completed, the material receiver 63 withdraws from the blank clamping mechanism 2, and the material receiver 63 withdraws with the milled rod. After the end, the rod is clamped by the articulated robot for subsequent processing.

[0055] Example 2

[0056] See also Fig. 9 As shown, the difference between this embodiment and embodiment 1 is that an elastic abutment joint 2311 is fixedly connected to the contact end between the first piston rod 231 and the cylindrical blank 24, the elastic abutment joint 2311 is made of rubber, and anti-slip grooves are provided on the contact surface between the elastic abutment joint 2311 and the cylindrical blank 24.

[0057] Example 3

[0058] See also Fig.11 As shown, the difference between this embodiment and embodiment 1 is that the inner end of the arc-shaped clip 631 away from the second piston rod 62 has a certain curvature to facilitate the insertion of the rod.

[0059] In the description of the present invention, unless otherwise specified, "plurality" means two or more than two; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
