Abstract

The invention discloses a tool head clamping device for a high-speed scratching testing machine. The tool head clamping device comprises a clamp body, a pull rod, an end cover, a hand wheel, a butter bar and a tool head; the clamp body is internally provided with counterbore holes and a conical hole; the pull rod is connected into the counterbore holes and connected with a thrust bearing; the end cover is connected to the upper surface of the clamp body; the hand wheel is fixedly connected to the top end of the pull rod; the cutter bar is connected to the position below the pull rod in an assembled and disassembled mode, the cutter bar is of a conical structure matched with the conical hole, and the conical structure is located in the conical hole; the tool head is connected to the lower portion of the cutter bar in an assembled and disassembled mode. By means of the tool head clamping device for the high-speed scratching testing machine, rapid assembling of the tool head can be achieved, repeated positioning precision of assembling of the tool head is high, and meanwhile high rigidity is achieved.

Description

technical field [0001] The invention relates to a tool head clamping device for a high-speed scratch testing machine. Background technique [0002] As an important method for in-depth understanding of grinding process, single abrasive grain scratch test has been widely used in recent years. In order to more realistically simulate the cutting conditions of abrasive grains in the grinding process, many scholars have designed high-speed scratch testing machines and carried out related experiments. In the high-speed scratch test, the abrasive particles are generally fixed on the tool head, and the tool head is fixed on the scratch test machine. Therefore, the clamping quality of the tool head becomes an important factor affecting the accuracy of the single abrasive scratch test. However, there is still a lack of a tool head clamping device with high rigidity, high clamping precision, and convenience. Contents of the invention [0003] The purpose of the present invention is ...
