The specific embodiment

below in conjunction with accompanying drawing and preferred embodiment of the present invention, technical scheme of the present invention is further elaborated.

referring to the slide rail type knife rest shown in Fig. 1, Fig. 2, it comprises tool rest 1, is rotatably located at the rotary head 2 of tool rest 1 front end, on rotary head 2, there are 6 stations, on 6 stations, be separately installed with cutter, by driving the station on the replaceable rotary head 2 of rotary head 2 rotation.This knife rest also comprises the slide rail 3 being fixed on knife rest 1 sidepiece, slide rail 3 vertically extends, on slide rail 3, be provided with slidably slide 4, on slide 4, be removably provided with two handle of a knifes 6, two handle of a knifes 6 are arranged along the vertical direction, and the axial line of two handle of a knifes 6 all parallels with the axial line of rotary head 2, on handle of a knife 6, the end of mounting cutter and rotary head 2 are positioned at the same side of tool rest 1.Tool rest 1 is provided with the driving mechanism 5 for driving slide 4 to slide up and down along the length direction of slide rail 3, and this driving mechanism 5 can just have hydraulic cylinder, thereby drive slides 4 to move up and down by hydraulic cylinder 5, the station of handle of a knife 6 is changed.

this knife rest also comprises retaining mechanism 7, makes the relative tool rest 1 of slide 4 fixing, thereby make handle of a knife 6 stably in corresponding station for slide 4 being locked on slide rail 3.Retaining mechanism 7 comprises locked cylinder, this locked cylinder comprises the cylinder barrel being fixedly installed on slide 4, expansion link that can be flexible vertically, the length bearing of trend of expansion link and the length bearing of trend of slide rail 3 are perpendicular, on slide 4, offer the through hole that can penetrate vertically for expansion link, on slide rail 3, offer a plurality of locating hole (not shown)s, these a plurality of locating holes are vertically arranged on slide rail 3, and the expansion link of locked cylinder can and be located in any one locating hole through above-mentioned through hole.When expansion link departs from from locating hole, slide 4 can slide up and down along slide rail 3 under the hydraulic cylinder effect of driving mechanism 5, and after expansion link penetrates in one of them locating hole, slide 4 is limited, and now the relative slide rail 3 of slide 4 and tool rest 1 are fixing.
