1 is an exploded perspective view of a tool holder using a supporting device according to the present invention; and FIG. 2 is an assembled view of the tool holder using the supporting device in FIG.

Referring to Figures 1 and 2, a preferred embodiment of the present invention provides a tool holder 300 using a support device 100, the tool holder 300 including the support device 100, and at least two tool holders 200. Provided on the support device 100.

The supporting device 100 includes a connecting plate 110 and a supporting plate 120. The connecting plate 110 is vertically fixed to one side edge of the supporting plate 120.

The connecting plate 110 is provided with a plurality of through holes 112 side by side for connecting the connecting plate 110 and the supporting plate 120 connected to the connecting plate 110 to a working table (not shown).

The support plate 120 includes an upper surface 121 and a lower surface 123 opposite to the upper surface 121. The support plate 120 is provided with two positioning holes 122 extending through the upper and lower surfaces 121 and 123 thereof. The set of positioning holes 122 are each used to position a corresponding tool holder 200. Each set of positioning holes 122 includes a central hole 124 extending through the support plate 120 and a plurality of concentric portions distributed at a center centered on the center hole 124 a guide groove 126 on the ring. The guide groove 126 has a circular arc shape. At least two sets of positioning holes 122 on the support plate 120 are respectively used to fix the seat 200.

The support device 100 can further include a plurality of bolts 140 that are inserted into the central hole 124 and the guide groove 126 and a nut 142 that cooperates with the bolt 140.

Each of the holders 200 is a rectangular parallelepiped having a tapered end portion. The holder 200 includes a top surface 210 and a plurality of side surfaces 212 perpendicularly intersecting the top surface 210. A recess 214 is formed in the top surface 210 of the seat 200 through the opposite sides 212 of the seat 200 for receiving a shank of a cutter (not shown). A plurality of through holes 216 extending perpendicularly through the blade holder 200 are respectively defined in the top surface 210 of the two sides of the recess 214. The through holes 216 are used to fix the blade holder 200 through the bolt 140 and the nut 142. The tool holder 300 is formed on the support plate 120. Openings 218 extending through the holder 200 are respectively formed on the bottom and the side walls of the recess 214 for inserting a cutter (not shown) into the recess 214, and using a fixing bolt to pass through the mounting hole The cutter 218 is secured to the recess 214 after the opening 218 is described. It will be appreciated that the at least two tool holders 200 can have different volumes so that different tool holders 200 can be flexibly used for different workpieces during machining.

Each of the holders 200 is fixed to the support plate 120 of the support device 100 by a plurality of bolts 140 and 142. The bolts 140 are inserted into the plurality of through holes 216 and the support plate 120 on the holder 200. The tool holders 200 are fixed to the lower surface 123 of the support plate 120 by the nuts 142 and the bolts 140. A bolt 140 and a nut 142 pass through the through hole 216 of the seat 200 and are inserted into the central hole 124 of the support plate 120. The other bolts 140 and 142 pass through the through holes 216 of the seat 200 and are placed on the support plate 120. In the guide groove 126.

During use, if the angle of the tool needs to be changed, only the nut 142 that fixes the seat 200 is loosened, so that the bolt 140 that is placed in the through hole 216 of the seat 200 and the guide groove 126 of the support plate 120 is inserted. The angle change of the blade holder 200 can be realized by rotating the bolt 140 placed in the center hole 124 of the support plate 120 by a certain angle. In this process, the original coordinates of the entire tool holder 200 are unchanged, thereby ensuring the machining accuracy of the workpiece. When the tool needs to be replaced, it is only necessary to move the tool holder 300 linearly through the table so that another tool fixed on the tool holder 300 can be moved to the desired position, thereby saving the original tool from being unloaded and reloaded. The inconvenience caused by the tool. At the same time, since the two tool holders 200 are mounted on the same support plate 120, the relative positions of the two tool holders 200 are fixed. Therefore, when the new tool is mounted thereon, the positioning accuracy of the tool is high, and the processing quality of the workpiece is not affected.
