Description

U 6 U / U / 97 /// L ds-.es (ttutJ The invention relates to a machine tool industry, in particular to tooling for CNC machines and automatic tool change. The toolholder is quick-change, the housing with a tool slot is rigidly connected a shank, designed with the body, intended for placement in the bearing socket of the cutting block, base surfaces made on the body and on the tail, for contacting with the response surfaces, made on the housing and in the supporting slot of the tool block, and a large surface made on the shank with the ability to interact with the counter surface of the stem of the toolholder clamping mechanism in the cutting block 1. The disadvantages of the known tool holder are the complexity of its construction, low accuracy based on the cutting block k lacking reliability during automatic change and during operation. The purpose of the invention is to simplify the design and increase the accuracy of the base, as well as to increase the reliability of work. This goal is achieved by the fact that in the tool holder there is a quick-changeable housing with an insert nest, a shank rigidly connected to the housing, designed to be placed in the bearing socket of the cutting block, made on the housing and on the shank base surfaces intended for contacting with the counter surfaces, made on the housing and in the bearing socket of the tool block, and the clamping surface made on the tailpiece with the possibility of interaction with the counter surface of the rod of the tool holder clamping mechanism In the incisal block, behind} the kimna surface of the tool holder shank is located on the protrusion made on the tail end from the side opposite to its base surface and at an angle of 45-55 to it. In this case, the base surfaces on the body are located one relative to another at an angle of 85-88. FIG. 1 shows a tool holder, front view; in fig. 2 - the same, top view; in fig. 3 - the same, in the expanded position after installation in the slot of the incisal block; in fig. 4 shows the type of toolholder for boring work in FIG. 5 - the same: for fastening the end tool. The toolholder includes a housing 1 with a shank 2. A slot 3 for the cutting tool 4 is made in the housing. On the housing 1, there are base surfaces 5 and 6, and on the shank 2 a base surface 7. With these surfaces, the tool holder is based on counter base surfaces made on the housing 8 of the incisal block and in its socket 9, where the tool holder shank is inserted. On the shank 2, on the side of the oppositely opposed base surface 7, there is a protrusion with a clamping surface 10 located at an angle of 45-55 ° to the base surface 7. The surface 10 is designed to interact with a counter clamping surface formed on the clamping rod 11 of the toolholder clamping mechanism in the tool block. A cutting tool, such as a turning tool, is installed in the slot 3 of the tool holder body and secured with screws 12. The end cutting tool 13 is held in a tapered bore 14 (Morse taper) by friction. The V-shaped grooves 15 are also provided on the toolholder housing 1, which serve to grip the toolholder body by means of the toolholder 16 grips 16 of the toolholder automatic replacement from the magazine (not shown). To increase the reliability of work by increasing the rigidity of the toolholder attachment in the tool block, the base surfaces 5 and 6 are made on the tool holder body at an angle of 85-88 ° one relative to the other. The tool-changer manipulator with the grippers 16 inserts the toolholder body 1 into the bearing seat 3 of the tool block. A clamping force F is applied to the clamping rod 11.

the direction of this force, the clamping rod 11 is moved and its clamping surface is in contact with the clamping surface 10 on the shank 2. Thereafter, the contacting clamping blade 11 and the toolholder body are moved together

before the contact of the base surfaces, 5-7 with the corresponding surfaces of the body of the cutting block and the support socket 3. Releasing the toolholder to change it is produced by moving the rod 11 in the opposite direction.
