[0002] In order to adapt to the development of various industries, the mechanical processing industry has become the mainstream of social development, especially the use of shaft parts, which runs through the lifeblood of the entire machine. However, the heat treatment process and processing technology of shaft parts have different production requirements according to different equipment types, different transmission torques and load bearing, etc. Especially for the processing technology of shaft parts, each process must be done to the extreme in order to meet the performance indicators of the whole machine, so as to maximize the efficiency of the machine itself. In the processing technology of shaft parts, when pre-drilling the center hole, the straightness of the center holes at both ends must be guaranteed without affecting the processing of the rough turning process, and the problem of large-diameter long shaft parts must be solved. At this stage, the traditional method is to place the shaft parts on the center stand. This method is cumbersome to operate and affects processing efficiency. For this reason, we propose a center hole punching machine. Utility Model Content

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] Example 1:

[0018] like Figure 1-2As shown, the center hole punching machine includes a support frame 1, a centering structure 2 is embedded in the upper surface of the support frame 1, a slide rail 3 is fixedly installed at one end of the support frame 1, a fixed seat 6 is fixedly installed at one end of the support frame 1 below the slide rail 3, a sliding structure 4 is slidably installed on the surface of the slide rail 3, a punching mechanism 5 is fixedly installed on the surface of the sliding structure 4, a servo motor 7 is fixedly installed on the lower surface of the fixed seat 6, and a screw rod 8 is fixedly connected to the output end of the servo motor 7;

[0019] The central mounting structure 2 includes a concave card 201 and a supporting V-shaped seat 202. The upper surface of the concave card 201 is fixedly installed with the supporting V-shaped seat 202. When the shaft part is placed on the supporting V-shaped seat 202, the midpoint of the cross section of the shaft part just above the supporting V-shaped seat 202 falls exactly at the bottom end of the clamping mouth of the supporting V-shaped seat 202. The central mounting structure 2 is provided with two. When the shaft part is placed on the supporting V-shaped seat 202, when the end face of the shaft part is close to the electric drill chuck 503, the center point of the cross section circle of the shaft part always coincides with the line drawn up and down by the center of the electric drill chuck 503. Therefore, the intersection of the two lines drawn is the center point of the cross section circle of the shaft part; the sliding structure 4 includes a mounting slide 401, a slider 402 and a spiral seat 403. The slider 402 is fixedly installed on one side of the mounting slide 401, and the spiral seat 403 is fixedly installed on the surface of the other side of the mounting slide 401; the surface of the fixed seat 6 is provided with an interlaced Hole 601, the screw rod 8 passes through the interlaced hole 601 and is spirally connected to the spiral seat 403, and the sliding structure 4 is slidably installed on the surface of the slide rail 3 through the slider 402; the punching mechanism 5 includes a mounting rod 501, a mounting chassis 502, an electric drill chuck 503, a driven wheel 504, an output wheel 505, an output motor 506 and a belt 507. The surface of the mounting rod 501 is fixedly mounted with a mounting chassis 502, and the surface of the mounting chassis 502 is movably mounted with an electric drill chuck 503. The electric drill chuck 503 is arranged in the middle position of the supporting V-shaped seat 202, and one end of the electric drill chuck 503 is fixedly mounted with a driven wheel 504, and the lower surface of the mounting chassis 502 is fixedly mounted with an output motor 506. The output end of the output motor 506 is fixedly mounted with an output wheel 505, and the output wheel 505 and the driven wheel 504 are movably connected by a belt 507; the electric drill chuck 503 is movably mounted with the mounting chassis 502 through a bearing.

[0020] It should be noted that the present invention is a center hole punching machine. When in use, the shaft parts are placed on the supporting V-shaped seat 202, and then the electric drill chuck 503 is unscrewed. First, the marker is inserted into the internal center position and fixed. Then, the servo motor 7 is controlled to control the screw rod 8 to rotate so that the mounting slide 401 moves from bottom to top, thereby driving the marker to draw a line on the end of the shaft parts. Then, the shaft parts are rotated to a certain angle, and the servo motor 7 is started again to drive the marker to move downward and draw a second line on the end of the shaft parts. At this time, the intersection of the two lines is the center point of the shaft parts. At this time, the marker is replaced with a drill bit and aligned with the center point. Then, the output motor 506 is started to punch holes in the shaft parts. After punching one end, the other end of the shaft parts is switched to punch. In this way, as long as the shaft parts are of the same diameter, they only need to be placed directly for punching. When encountering shaft parts of different diameters, the above operation needs to be repeated to find the center point.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
