Abstract
The utility model discloses a tool holder with an adjustable center height of the point of a cutter and used in a turning tool. The tool holder comprises a tool holder main body; the tool holder main body comprises a fastening end used for fastening the cutter and a supporting end used for supporting the cutter; and a screw mounting hole for mounting a fastening bolt is arranged at the fastening end, and a height adjusting device used for adjusting the height of the cutter is arranged at the supporting end of the tool holder main body. The tool holder has a simple structure, and has the advantages that not only the turning tool replacement is convenient and fast, but also the center height of the point of the cutter can be accurately adjusted, so as to greatly improve the processing precision of processed workpieces.
Description
Technical field
The utility model relates to a kind of turning tool rest on lathe or the instrument lathe that is used to be installed in, and especially relates to the high adjustable turning tool rest of a kind of cutter nose center.
Background technology
In mechanical processing industry, turning processing is a kind of machining mode commonly used, and in process, the replacing of cutter is extremely inconvenient, shows that mainly lathe tool nose center height is bad definite.At present; Traditional method adds several parallels below lathe tool; Because the lathe tool height is inconsistent,, promptly make the lathe tool point of a knife aim at the center of workpiece to be machined through the quantity that increases or reduce parallels so lathe tool of every replacing all will be adjusted the centre-height of lathe tool point of a knife again.Because the thickness specification of parallels is limited, therefore, this mode of parallels that below lathe tool, adds has not only increased the time of tool changing, and the center that the lathe tool point of a knife of often installing can not very accurate alignment pieces, thereby influences the machining accuracy of workpiece to be machined.
The utility model content
The technical problem that the utility model will solve provides a kind of simple in structure; Lathe tool is changed easily and fast; But also can accurately adjust lathe tool nose center height, thereby improve the high adjustable turning tool rest of cutter nose center of workpiece to be machined machining accuracy greatly.
For solving the problems of the technologies described above; The high adjustable turning tool rest of a kind of cutter nose center of the utility model; Comprise the knife rest main body; This knife rest main body comprises the support end of holding and being used to support cutter that tightens up that is used to tighten up cutter, and this tightens up end and is provided with the installation screw that trip bolt is installed, and the support end of said knife rest main body is provided with the height-regulating device that is used to adjust the cutter height.
A kind of improvement as the utility model; The said height-regulating device that is used to adjust the cutter height comprises and can do the top board that moves up and down, two wedges that are arranged on the move left and right in the horizontal direction of this top board below along the support end vertical direction, and is arranged on being used between two wedges and drives these two wedges turbine and worm mechanism of moving of two ends to the left and right in the horizontal direction; Said top board has and said two inclined-planes that wedge matches.
Adopt the high adjustable turning tool rest of cutter nose center of said structure; When adjustment cutter nose center is high, only need regulate turbine and worm mechanism; And then two wedges of move left and right; Top board is done along the support end vertical direction moved up and down, thereby the height of adjustment cutter on turning tool rest reaches the high purpose of adjustment cutter nose center.The utility model is simple in structure, and is easy to operate, need not unload bottom tool during adjustment cutter height, directly regulates turbine and worm mechanism and can achieve the goal.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done to specify further.
Fig. 1 is the perspective view of the high adjustable turning tool rest of a kind of cutter nose center of the utility model.
The specific embodiment
Referring to Fig. 1; The high adjustable turning tool rest of a kind of cutter nose center of the utility model; Comprise knife rest main body 1; This knife rest main body 1 comprise be used to tighten up cutter tighten up end 2 and the support end 3 that is used to support cutter, this tightens up end 2 and is provided with the installation screw 4 that trip bolt is installed, the support end 3 of said knife rest main body 1 is provided with the height-regulating device that is used to adjust the cutter height.
The said height-regulating device that is used to adjust the cutter height comprises two wedges 6,7 of the move left and right in the horizontal direction that can do the top board 5 that moves up and down along support end 3 vertical direction, be arranged on these top board 5 belows, and is arranged on two wedges 6, being used between 7 and drives these two wedges 6,7 turbine and worm mechanism 8 of moving of two ends to the left and right in the horizontal direction; Said top board 5 has the inclined-plane that matches with said wedge 6,7.
The two ends of top board 5 are respectively equipped with spacing hole 11,12, and the support end 3 of said knife rest main body 1 is provided with the spacing guide rod 9,10 that matches with spacing hole 11,12.The bottom of two of move left and right wedges 6,7 is respectively equipped with dovetail groove 13,14 in the horizontal direction, and the end face of said support end is provided with the guidance tape 15,16 that matches with this dovetail groove 13,14.
Be placed on cutter on the top board 5 during use; Revolving wormgear worm mechanism 8; Through the positive and negative pair of nut on the worm screw wedge 6,7 is moved at two ends to the left and right, pass through the displacement of the horizontal direction of dovetail groove 13,14 and guidance tape 15, the engagement limits wedge between 16 6,7 in the moving process, through the vertical displacement direction that spacing guide rod 9,10 and cooperating of spacing hole 11,12 limits top board 5; Cutter on the top board 5 is risen, play the high purpose of adjustment cutter nose center.
