DETAILED DESCRIPTION

[0014] Reference Figure 1 to Figure 2 The utility model is further described in detail.

[0015] A driving wheel transfer pressing device comprises a mounting frame 001, on which a positioning support assembly for placing a long-axis short-shaft shoulder workpiece 02, a clamping assembly for clamping the long-axis short-shaft shoulder workpiece 02, and a rotating assembly for rotating the long-axis short-shaft shoulder workpiece 02 are installed.

[0016] The positioning support assembly includes a positioning support plate 03 mounted on the mounting frame 001 and an axial positioning block 05 mounted on the positioning support plate 03. The long-axis short-shaft shoulder workpiece 02 is placed on the positioning support plate 03, and the axial positioning block 05 is in conflict with the long-axis short-shaft shoulder workpiece 02.

[0017] The rotating assembly includes a driving wheel motor 07 mounted on a mounting frame 001 and a driving wheel 01 connected to the driving wheel motor 07. The driving wheel 01 contacts the long-axis short-shaft shoulder workpiece 02, and the pressing wheel cylinder 06 drives the driving wheel 01 to rotate to rotate the long-axis short-shaft shoulder workpiece 02.

[0018] The clamping assembly includes a pressure wheel 04 and a pressure wheel cylinder 06. The pressure wheel cylinder 06 is installed on a mounting frame 001. A slide plate fixing seat 08 is installed on the mounting frame. A pressure wheel slide plate 09 is slidably connected to the slide plate fixing seat 08. The pressure wheel slide plate 09 is connected to the output end of the pressure wheel cylinder 06. The pressure wheel 04 is installed on the pressure wheel slide plate 09 and contacts the long-axis short-axis shoulder workpiece 02. The pressure wheel 04 and the driving wheel 01 cooperate to clamp and fix the long-axis short-axis shoulder workpiece 02 on the positioning support plate 03.

[0019] Working principle: put the long-axis short-shaft shoulder workpiece 02 onto the positioning support plate 03, the driving wheel 01 is radially tangent to the long-axis short-shaft shoulder workpiece 02 to form a two-point support to position the long-axis short-shaft shoulder workpiece 02 on the positioning support plate 03, the axial positioning block 05 contacts the long-axis short-shaft shoulder workpiece 02 to position the axial movement of the long-axis short-shaft shoulder workpiece 02, and prevents the axial movement of the long-axis short-shaft shoulder workpiece 02 from affecting the grinding of the long-axis short-shaft shoulder workpiece 02, and cooperates with the pressure wheel cylinder 06 to drive the pressure wheel slide plate 09 to slide on the track on the slide plate fixed seat 08 through the groove on the pressure wheel slide plate 09, so that when the pressure wheel cylinder 06 is working, it drives the pressure wheel 04 installed on the pressure wheel slide plate 09 to radially contact and press the long-axis short-shaft shoulder workpiece 02, and then cooperates with the driving wheel 01 to form a three-point support to press and fix the long-axis short-shaft shoulder workpiece 02 on the positioning support plate 03, so that the clamping of the long-axis short-shaft shoulder workpiece 02 is simple and fast, and the production efficiency is improved;

[0020] The driving wheel motor 07 drives the driving wheel 01 to rotate, and the driving wheel 01 is radially tangent to and in conflict with the long-axis short-shaft shoulder workpiece 02, so that when the driving wheel 01 rotates, the long-axis short-shaft shoulder workpiece 02 is driven to rotate by friction, which is convenient for the grinding equipment to grind the long-axis short-shaft shoulder workpiece 02. The clamping and positioning of the long-axis short-shaft shoulder workpiece 02 uses the plane of the positioning support plate 03 as the radial reference, and its rotation accuracy is little affected by the driving wheel 01 and the pressure wheel 04. Therefore, when other grinding equipment grinds the long-axis short-shaft shoulder workpiece 02, the accuracy reduction caused by the position offset of the long-axis short-shaft shoulder workpiece 02 is avoided. Therefore, a very high rotation accuracy can be guaranteed, and the processing accuracy of the long-axis short-shaft shoulder workpiece 02 is improved.

[0021] A guide hole 010 is formed on the axial positioning block 05 , and a clamping rod 011 threadedly connected to the guide hole 010 is provided on the axial positioning block 05 . The clamping rod 011 abuts against the long-axis short-axis shoulder workpiece 02 .

[0022] The clamping rod 011 threadedly connected to the guide hole 010 is rotated so that the clamping rod 011 contacts the bottom end surface of the long-axis short-shaft shoulder workpiece 02, so that the axial positioning block 05 contacts the long-axis short-shaft shoulder workpiece 02 to position the axial movement of the long-axis short-shaft shoulder workpiece 02. The clamping rod 011 is threadedly connected to the guide hole 010 so that the clamping rod 011 can be moved. It is convenient to rotate the clamping rod 011 according to the length of the long-axis short-shaft shoulder workpiece 02 to make it contact with the long-axis short-shaft shoulder workpiece 02, thereby avoiding the long-axis short-shaft shoulder workpiece 02 The machining accuracy is reduced due to the difference in length of the long-axis short-shaft shoulder workpiece 02 affecting the axial positioning of the long-axis short-shaft shoulder workpiece 02, thereby improving practicality.

Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
