Specific embodiment
With reference to specific attached drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, numeral-controlled internal grinder special fixture described in the utility model includes clamping fixture seat 17, clamping fixture seat 17
Middle part sets the platen 3 that can be moved left and right, and pushing rod sleeve 2 is set on platen 3, coordinates pull rod 1, pull rod 1 and fixture in pushing rod sleeve 2
The piston rod connection of oil cylinder is moved left and right with realizing；Film 5 is connected on the clamping fixture seat 17, film 5 is located at the right side of platen 3
Pawl seat 16 is bolted on film 5, claw 15 is connected in pawl seat 16 for side, in 5 right side setting terminal pad 6 of film, terminal pad
6 right side is used to install tooth mould 11 or end surface supporting 13；On the right side of the platen 3, compression axis 8, one end of compression axis 8 are set
It is rotatablely connected with platen 3 by axis pin, spring 4 is set on axis pin, the other end of compression axis 8 is connect with one end of connecting shaft 9, even
The other end connection claw 10 of spindle 9, is provided with card slot on compression axis 8, screw 7 is disposed radially in terminal pad 6, pressing
During mandrel 8 is moved left and right, screw 7 can be slipped into along the surface of compression axis 8 in card slot.
The operation principle and the course of work of the utility model：
It is as shown in Figure 1 the first use state, when processing the first test specimen 12, under the action of fixture oil cylinder, 1 band of pull rod
