Abstract
A machine tool fixture is used for clamping a conical gear for inner hole grinding on a grinding machine. The machine tool fixture comprises a spindle flange and a pull rod in a spindle hole, wherein a through hole is formed along the axis per se of the spindle flange on the spindle flange. The machine tool fixture further comprises a flexible disc, a plurality of jack catches, a positioning fluted disc and a push-and-pull disc, wherein the flexible disc is coaxially arranged on one end surface of the spindle flange, and the part of the flexible disc, which is close to the outer edge, is fixedly connected with the spindle flange; the jack catches are circumferentially distributed around the axis of the spindle flange and arranged on one end surface of the flexible disc; the positioning fluted disc and the spindle flange are coaxially arranged and connected through a positioning block, the positioning block penetrates through the flexible disc in a clearance fit way, a central through hole is formed on the positioning fluted disc in the axial direction, and teeth matched with the conical gear are formed on one end surface of the positioning fluted disc; the push-and-pull disc is positioned in the through hole on the spindle flange and is in coaxial slide fit with the through hole; and one end of the push-and-pull disc is connected with the pull rod, and the other end of the push-and-pull disc corresponds to the central part of the flexible disc. The machine tool fixture is convenient to adjust, and the precision of processed parts is good.
Description
Technical field

Background technology
Know with the provisional capital, in machining, the tooth Profile Machining of bevel gear, be to use special-purpose tooth Profile Machining lathe, other position then processes on other machine tool, for the general bore of quality of fit that improves gear and axle all needs through grinding process, and the operating accuracy that will guarantee gear just necessarily requires the benchmark of endoporus and profile of tooth to unify, usually each part all will pass through careful centering when clamping, or the special-purpose anchor clamps of employing, but existing anchor clamps exist some and use inconvenience, the not high shortcoming of operating accuracy.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of jig, is applied to machining bevel gears part on the grinding machine, and anchor clamps are easy to adjust, and the processing parts precision is good, can satisfy instructions for use.
For addressing the above problem, the utility model by the following technical solutions: this jig, comprise that main shaft connects dish, is positioned at the pull bar of spindle hole, main shaft connects rim self axis one through hole is set, and also comprises:
Resilient disc, coaxial being arranged on the end face that described main shaft connects dish, and the place, close outer of resilient disc and main shaft to connect dish affixed;
Claw is provided with a plurality ofly, connects the axis circle distribution of dish and all is arranged on the end face of resilient disc around main shaft;
The location fluted disc connects the coaxial setting of dish with described main shaft and is connected by locating piece, and resilient disc is passed in described locating piece gap, and the positioning tooth rim axially is provided with a central through hole, locatees fluted disc one side end face and is provided with the tooth that can cooperate with bevel gear;
The push-and-pull dish is positioned at described through hole and coaxial being slidingly matched that main shaft connects dish, and push-and-pull dish one end is connected with described pull bar, and the other end is corresponding with described resilient disc centre.
As further technical scheme of the present utility model:
In this jig, be threaded between described push-and-pull dish and the described pull bar, and be provided with the adjustment cushion cover between push-and-pull dish and the pull bar.
In this jig, the axis that connects dish around described main shaft also is laid with a plurality of clamps, and described clamp and described claw connect one to one, and threaded engagement has the adjustment screw that can radially adjust clamp on the claw.
The beneficial effects of the utility model are: can change adjustment cushion cover, the location fluted disc of different-thickness and pass through the adjustment clamp according to different part needs in use, the anchor clamps versatility is good, adjusts easily, and easy to operate, the processing parts precision is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the structural representation of the utility model embodiment,
Among the figure: 1 main shaft connects dish, 2 resilient discs, and 3 locating pieces, 4 pull bars, 5 adjust cushion cover, 6 push-and-pull dishes, 7 adjust screw, 9 claws, 10 clamps, 12 location fluted discs, 13 workpiece.
The specific embodiment
As shown in Figure 1, this jig comprises that mainly main shaft connects dish 1, pull bar 4, resilient disc 2, claw 9, location fluted disc 12, push-and-pull dish 6.Pull bar 4 is positioned at spindle hole.Main shaft connects dish 1 and along self axis one through hole is set.
Claw 9 is provided with a plurality of, connects dish 1 axis circle distribution and all is arranged on the end face of resilient disc around main shaft.Connect dish 1 axis around described main shaft and also be laid with a plurality of clamps 10, clamp 10 connects one to one with described claw 9, and threaded engagement has the adjustment screw 7 that can radially adjust clamp on the claw 9.
