Abstract
The invention discloses a lathe fixture for quickly assembling and disassembling shafts, which comprises an elastic clamp sleeve, an inner taper sleeve, an oil seal, a bearing, a check ring, a handle, a thrust sleeve, a shell and a main shaft, wherein the left shaft end of the elastic clamp sleeve is matched with an inner taper hole of the rotary main shaft, while the right shaft end is matched with the inner taper sleeve to form an expansion structure; the left end face of the shell is fixed on the outer wall of a static lathe head; an inner hole does not contact with the stretched main shaft; the outer wall of the shell is connected with the thrust sleeve through threads; the handle for the convenience of operation is arranged on the outer wall of the thrust sleeve; and an inner hole at the right end of the thrust sleeve is connected with the outer wall of the inner taper sleeve through the single-row tapered roller bearing. The lathe fixture can realize the operation of assembling or disassembling the shafts by operating the handle without stopping to save the nonproductive time, improve the working efficiency and be suitable for processing batch shafts.
Description
Technical field
The present invention relates to a kind of vehicle clamper, specifically, the present invention relates to a kind of quick dispatch anchor clamps of turning axle spare.
Background technology
The method of clamping that axial workpiece turning adds man-hour mainly contains the centering chuck clamping, heart carrier clamps and expansion set clamps, and these anchor clamps that clamp forms all need be realized the clamping of axle or unload under parking condition.Frequent Brake stop and starting must waste electric energy, and the unproductive time of charge and discharge operations are also longer in the batch process, and its production efficiency is lower, are not suitable for axle turning processed and applied in batches.
Summary of the invention
The present invention is primarily aimed at prior art realizes the axle loading and unloading under dead ship condition deficiency, proposes a kind of lathe fixture for quickly assembling and disassembling shafts with expansion set structure.This clamp structure is simple, realizes the loading or unloading operation of axle part under parking condition not.
The present invention is achieved through the following technical solutions technical goal.
Lathe fixture for quickly assembling and disassembling shafts, it is made of elastic jacket, inner conical drogue, oil sealing, bearing, back-up ring, handle, thrust housing, shell and main shaft.Described elastic jacket left end tapering axle directly cooperates with the main shaft internal taper hole of rotation, and right-hand member is the expansion set structure, inner conical drogue and elastic jacket right-hand member outer wall taper fit.Described shell is a sleeve-like configuration, and its left end end face of flange is fixedlyed connected with static geared head outer wall, and endoporus does not contact mutually with the main-axis end that stretches into.Described thrust housing is threaded with outer shell outer wall, and the thrust housing outer wall is radially installed handle.Improvements are: be connected by bearing between described thrust housing right-hand member endoporus and the inner conical drogue outer wall, the bearing both sides are set up oil sealing and back-up ring separately.
Bearing in the said structure is a single-row tapered roller bearing, and its inner ring cooperates with the inner conical drogue outer wall and with the elastic jacket rotation, the outer ring cooperates with relative static thrust housing endoporus.Do not clockwise rotating thrust housing by handle under the parking condition, bearing outer ring is moved to the left with thrust housing, and the internal taper hole of bearing outer ring is cooperated with roller, promotes inner conical drogue and is moved to the left the locking elastic jacket, realizes the clamping of axle part.Be not rotated counterclockwise thrust housing by handle under the parking condition, then the internal taper hole of bearing outer ring does not contact with roller, and inner conical drogue moves to right under the expansive force of elastic jacket, and the axle part loses constraint and can easily unload.
The present invention compared with prior art has following good effect.
1, simple in structure, easy to manufacture, easy to operate;
2, not realizing installation of axle part or unloading operation under the parking condition, reduced unproductive time, the production efficiency height;
3, not realizing installation of axle part or unloading operation under the parking condition, avoid lathe necessary electromotor Fraquent start and Brake stop, reduce electric energy loss.
Description of drawings
Accompanying drawing is a structural profile schematic diagram of the present invention.
The specific embodiment
The invention will be further described with reference to the accompanying drawings below.
Lathe fixture for quickly assembling and disassembling shafts shown in the drawings, it is made of elastic jacket 1, inner conical drogue 2, oil sealing 3, bearing 4, back-up ring 5, handle 6, thrust housing 7, shell 8 and main shaft 9.Described elastic jacket 1 left end tapering axle directly cooperates with main shaft 9 internal taper holes of rotation, and right-hand member is the expansion set structure, and its endoporus cooperates with the between centers crack that is mounted, elastic jacket 1 right-hand member and inner conical drogue 2 taper fit.The left end end face of flange of shell 8 is fixedlyed connected with static geared head outer wall, and endoporus does not contact mutually with main shaft 9 axle heads that stretch into.Thrust housing 7 is connected with shell 8 outer wall threads, and thrust housing 7 outer walls are installed the handle 6 of being convenient to operative employee's operation.Be connected by single-row tapered roller bearing 4 between thrust housing 7 right-hand member endoporus and inner conical drogue 2 outer walls, bearing 4 both sides are set up oil sealing and back-up ring 5 separately.Bearing 4 inner rings cooperate with inner conical drogue 2 outer walls and with elastic jacket 1 rotation, bearing 4 outer rings cooperate with relative static thrust housing 7 endoporus.During actual the use, can not clockwise rotate thrust housing 7 by handle 6 under the parking condition, bearing 4 outer rings are moved to the left with thrust housing 7, and the internal taper hole until the outer ring cooperates with roller, promote inner conical drogue and are moved to the left locking elastic jacket 1, realize the clamping of axle part.Be not rotated counterclockwise thrust housing 7 by handle 6 under the parking condition, then the internal taper hole of bearing 4 outer rings does not contact with roller, and inner conical drogue 2 moves to right under the expansive force of elastic jacket 1, and the axle part loses constraint and can easily unload.
