Abstract
The utility model discloses a safe spanner for a lathe chuck. The safe spanner for the lathe chuck comprises a rotary rod and an operating handle mounted at the upper end of the rotary rod. A guide sleeve is movably arranged on the rotary rod in the axial direction. The two sides of the guide sleeve are respectively provided with a guide groove in the axial direction. Hinge pins are fixed to the two sides of the rotary rod, wherein the outer ends of the hinge pins are movably assembled in the guide grooves. A compression spring is assembled between the inner surface of the guide sleeve and the outer surface of the rotary rod, wherein one end face of the compression spring is fixed to the hinge pins, and the other end face of the compression spring is fixed to the guide sleeve. A shaft collar is arranged on the rotary rod, a bulge loop is arranged in the guide sleeve, and the shaft collar prevents the bulge loop from moving along one end of the rotary rod in the axial direction. An observation hole is further machined in the guide sleeve so that the condition that the rotary rod is aligned with a chuck square hole can be observed conveniently. In the using process, the movable guide sleeve pushes the rotary rod of the chuck out of the chuck square hole under the action of compressed spring force, so that the phenomenon that a user forgets to dismantle the chuck spanner is completely eradicated; due to the fact that the contact area on the lower end face of the guide sleeve is relatively large, the guide sleeve can be arranged around the chuck square hole conveniently in a supporting mode.
Description
Technical field
The utility model relates to lathe tools, especially a kind of lathe chuck safe wrench.
Background technology
During general factory process is produced, the most frequently used to spanner be exactly chuck handle.Operator is by chuck handle by Workpiece clamping or unclamp, and chuck handle is the most used and necessary instrument in lathe processing, if do not have chuck handle just cannot make workpiece location or clamping, cannot realize the object of utilizing lathe to carry out production and processing.
In lathe work practice production and processing, the safety operation of lathe is that teacher and production manager drum in and required link.According to lathe safety regulation for operations, operator is when using scroll chuck clamping work pieces, and chuck handle must take off after using immediately, then starts processing.Operator just can not have an accident in strict accordance with safety regulation for operations operation, but indivedual operators particularly rigidly connect apprentice or the student who touches lathe, and often negligence is forgotten and taken off spanner, thereby produces security incident.
Chinese patent 200820175714.6 discloses a kind of lathe chuck spanner safety arrangement, the driving end of former chuck handle is lengthened, and on driving end, pacify a spring, and the internal diameter of spring is slightly larger than driving end cross section quadrangle diagonal.During use, operator aims at chuck square hole by driving end and slightly firmly presses down, and spring is compressed by chuck, driving end stretches out spring, enters duty, when operating while finishing using not the application of force, under the effect of spring, make driving end automatically exit chuck square hole, thereby guaranteed the safety of operation.
Yet in use, the free end of above-mentioned spanner spring is difficult for being fixed on chuck square hole around, easily slide and be stuck in the square hole of chuck, cause inconvenient operation.
Summary of the invention
For the deficiencies in the prior art part, the utility model aims to provide a kind of lathe chuck safe wrench, guarantees when clamping or unclamping chuck convenient and reliable operation.
The technical solution adopted in the utility model: a kind of lathe chuck safe wrench, comprise swing arm and the operating grip that is loaded on swing arm upper end, in the axial activity of swing arm, a pilot sleeve is set, in the axial both sides of pilot sleeve, gathering sill is set respectively, in swing arm both sides, be fixed with bearing pin, the activity of bearing pin outer end is assemblied in gathering sill, between pilot sleeve inner surface and swing arm outer surface, be equipped with Compress Spring, Compress Spring one end face is fixed on bearing pin, and Compress Spring other end is fixed on pilot sleeve.
On swing arm, be provided with the axle collar, bulge loop is set in pilot sleeve, the axle collar blocks bulge loop and moves axially along swing arm one end.
On pilot sleeve, be also processed with and observe groove square hole, to facilitate, observe swing arm aligning chuck square hole.
When using chuck handle, pilot sleeve is aimed to chuck upper aperture, firmly press down operating grip, activity-oriented sleeve is fixed, insert in chuck square hole to realize workpiece loading and unloading swing arm lower end; After finishing using, loose one's grip, chuck handle is not stressed, swing arm resets under Compress Spring effect, swing arm head exits in chuck square hole, stop like this to forget and take off chuck handle phenomenon, because pilot sleeve lower surface contact area is relatively large, to be convenient to be supported in around chuck square hole, operating process is convenient and reliable.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation;
Fig. 2 is the utility model embodiment 2 structural representations;
In accompanying drawing: 1 swing arm 2 handle 3 pilot sleeve 4 gathering sill 5 bulge loop 6 axle collar 7 Compress Spring 8 bearing pin 9 peep holes.
The specific embodiment
Embodiment 1: as shown in Figure 1, a kind of lathe chuck safe wrench, comprise swing arm 1 and the operating grip 2 that is loaded on swing arm 1 upper end, there is an assembling square hole swing arm 1 upper end, handle 2 is fixed on swing arm 1 through assembling square hole, in the axial activity of swing arm 1, a pilot sleeve 3 is set, in the axial both sides of pilot sleeve 3, be processed with respectively gathering sill 4, gathering sill 4 has certain length, this length is with suitable with the chuck square hole degree of depth, in swing arm 1 both sides, be fixed with bearing pin 8, bearing pin 8 outer end activities are assemblied in gathering sill 4, and bearing pin 8 can move up and down in gathering sill 4.
On swing arm 1, be provided with the axle collar 6, at the interior bulge loop 5 that arranges of pilot sleeve 3, the axle collar 6 blocks bulge loop 5 and moves axially along swing arm one end, between pilot sleeve 3 inner surfaces and swing arm 1 outer surface, be equipped with Compress Spring 7, Compress Spring 7 one end faces are fixed on bearing pin 8, Compress Spring 7 other ends are fixed on the bulge loop 5 of pilot sleeve 3, while being swing arm 1 reset, swing arm 1 moves up under Compress Spring 7 effects, when swing arm 1 head exits chuck square hole, bulge loop 5 is stuck on the axle collar 6, and swing arm 1 moves up and stops.
Embodiment 2: as shown in Figure 2, the essential structure of embodiment 2 is identical with embodiment 1, in embodiment 2,
In pilot sleeve 3 bottoms, be also processed with two peep holes 9, to facilitate observation swing arm whether to aim at chuck square hole, like this more convenient operation.
