Description

Technical Field

[0001] The utility model belongs to the field of tool holders, and in particular relates to a pneumatic tool holder for a grinding machine. Background Art

[0002] During use, the existing knife sharpener will install the long strip tool that needs to be sharpened on the material table. Generally, the tool that needs to be sharpened is inserted horizontally on the material table, and then the grinding head grinds the tool. However, during the grinding process, the grinding head will produce a certain vibration to the tool when it is working. Especially when the tool is long, it is very likely to cause the tool to break during the working process. At the same time, the vibration of the tool may cause the grinding accuracy to decrease, which ultimately leads to the problem of low working efficiency of the knife sharpener. Therefore, it is necessary to design a pneumatic tool holder for a grinder to solve the above problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a pneumatic tool holder for a grinder to solve the problem raised in the above background technology that when grinding tools on the existing market, long tools are not placed stably and will vibrate, thereby affecting the grinding accuracy and grinding efficiency.

[0004] In order to achieve the above object, the technical solution of the utility model is as follows:

[0005] A pneumatic tool holder for a grinder comprises a base, a support seat is fixed on the base, a mounting groove is provided on the support seat, a rotating shaft is fixed on the support seat, a support column is rotatably connected to the rotating shaft via a bearing, a receiving block for placing a tool is provided on the support column, a telescopic cylinder for driving the support column to rotate around the rotating shaft is also provided on the support seat, and the support column is arranged in the mounting groove.

[0006] As a further improvement to the utility model, a driving block is provided at the output end of the telescopic cylinder, and a first slope is provided on the top end of the driving block away from the telescopic cylinder.

[0007] As a further improvement to the utility model, a second slope surface matched with the first slope surface is provided at the bottom end of the support column, and a stopper is provided on a side of the second slope surface close to the telescopic cylinder.

[0008] As a further improvement to the present invention, the first slope surface and the second slope surface have the same slope.

[0009] As a further improvement of the utility model, a buffer column is provided on a side of the base away from the telescopic cylinder, and the buffer column includes a column and a silicone pad provided on the top of the column.

[0010] As a further improvement of the utility model, the receiving block includes a connecting block detachably connected to the supporting column, a placing block is provided at the top of the connecting block, and a groove for placing a tool is provided at the top of the placing block.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model drives the driving block to extend and retract by the telescopic cylinder, and the driving block drives the supporting column to rotate around the center of the rotating shaft, so that the supporting column is in a horizontal or upright state, and the state is switched according to the demand. When it is necessary to grind a long tool, the driving cylinder is extended to make the supporting column vertically set. At this time, the tool is just placed on the receiving block, so that the tool can be stably placed during grinding, preventing the vibration of the tool, thereby enhancing the grinding accuracy and improving the processing efficiency of the tool.

[0013] The utility model arranges a buffer column on the base at a side far from the telescopic cylinder, so that when the support column is in a horizontal state, the buffer column can resist the support column to prevent the support column from continuing to rotate downward; BRIEF DESCRIPTION OF THE DRAWINGS
