Extrusion Grinder

Extrusion grinder

The utility model relates to an improved extrusion grinder, which belongs to a grinding equipment that uses abrasive flow processing technology to precisely process the surface of a workpiece. The International Patent Classification Number is B24B.

The existing extrusion grinder mainly consists of a frame [1], a motor [2], an oil tank [3], an oil pump [4], a column [10], an upper abrasive cylinder [5], and an upper working cylinder [6]. The lower abrasive cylinder [7], the lower working cylinder [8], the clamping cylinder [9], etc. are composed in a known manner. The deformable polymer mixed with abrasive is squeezed by hydraulic control to make it flow over the surface of the workpiece to be processed. In order to achieve the purpose of deburring, grinding round corners or surface polishing. The technology of the extrusion grinder is in the Extrude Hone Corp. (Extrude Hone Corp.) 77C type extrusion honing machine product specification, the United States patent USPat, 3,769,751 and the American Society of Mechanical Engineers (SME) Proceedings MR80-340 Has been made public. Because the two clamping cylinders are located on both sides of the lower abrasive cylinder [7] at the bottom of the worktable [13]. The clamping cylinder (9) and the piston rod (12) of the clamping cylinder reciprocating up and down occupy part of the space in the upper and lower parts of the worktable. Not only the oil tank, oil pump, motor, integrated valve, etc. have to be installed in another box outside the body. It increases the floor area and reduces the effective working area for placing fixtures and workpieces, which limits the geometric dimensions of fixtures and workpieces.

The task of the utility model is to rationalize the original structure design and increase the effective working area.

The above task is accomplished in the following way: install the two clamping cylinders [9] in the two hollow uprights [10] respectively, and fix the clamping cylinder piston rod [12] on a movable beam [11]. The movable beam is fixedly connected with the upper abrasive cylinder (5) and the upper working cylinder (6). In this way, the effective working area between the uprights is significantly increased. The diameter of the fixture can be increased, so that the maximum geometric size of the workpiece that can be processed increases, and the number of workpieces of the same size that can be ground at the same time can be increased, which not only expands the processing range, but also improves work efficiency.
