Abstract
The utility model relates to a novel safe clamping wrench for a chuck of a machine tool. The novel safe clamping wrench comprises a wrench bar and a wrench head, wherein the wrench head is connected with one end of the wrench bar and extends into a fastening hole of the chuck. A handle is arranged at the other end of the wrench bar. A through hole is formed in the wrench bar in the length direction of the wrench bar. The through hole extends to the wrench head. A slide bar and a spring are arranged in the through hole. One end of the spring is connected with the slide bar. The other end of the spring is connected with a limiting plug fixedly arranged in the through hole. Compared with the prior art, the novel safe clamping wrench can effectively overcome potential safety hazards existing in the using process of a traditional machine tool wrench, avoid safety accidents, improve production efficiency and lower production cost; meanwhile, the novel safe clamping wrench is simple in production process, low in machining cost and capable of meeting use requirements.
Description
Technical field
The utility model relates to machine chuck spanner.
Background technology
In industrial manufacture process, machining is widely used in the every field of producing, and in the production of all trades and professions, it is very extensive that three-jaw, chuck are applied in China's machine tooling industry, become the requisite part of clamping workpiece to be machined in the lathe course of work.And in the process of clamping workpiece, for by workpiece regular worker chuck, must with chuck handle by Workpiece clamping on chuck.In the process of Workpiece clamping, the easy operate miss because of workman, or bad operating habit, clamping spanner is not shifted out in time from three-jaw chuck fastener hole, once lathe is opened, main shaft rotates, and under the drive of the centrifugal force that clamping spanner will produce after main shaft rotation, fly out, and the personnel that cause injure and the security incident such as property damage.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of simple in structure, safe and practical machine chuck safe clamping spanner.
The utility model solves the problems of the technologies described above adopted technical scheme: the safe clamping spanner of novel lathe chuck, comprise that wrenching bar is connected with this wrenching bar one end and stretches into the driving end in chuck fastener hole, the wrenching bar other end is provided with handle, in wrenching bar, opened along its length through hole, this through hole extends to described driving end, in through hole, be provided with slide bar and spring, spring one end is connected with slide bar, and the other end is connected with the limit plunger in being installed in through hole.
As preferably, described through hole is step through-hole, the hole, small-bore of this step through-hole extends to described driving end, the described slide bar sliding along this hole is installed in hole, described small-bore, driving end is stretched out in this slide bar one end, the other end is connected with slide bar head, and slide bar head is resisted against on the step surface of described step through-hole; In the hole, large aperture of step through-hole, described spring and limit plunger are installed, one end is resisted against on slide bar head described in spring.
As preferably, the one end away from driving end in hole, large aperture is provided with internal thread, and described limit plunger is by internal thread precession through hole.
The utility model compared with prior art, can effectively overcome traditional machine tool spanner potential safety hazard in use, avoids the generation of security incident, enhances productivity, and reduces production costs; Meanwhile, the production technology of safe clamping spanner of the present utility model is simple, and processing cost is low, can guarantee instructions for use.
Accompanying drawing explanation
Fig. 1 is the structural representation of wrenching bar and driving end in the utility model;
Fig. 2 is the package assembly schematic diagram of the utility model optimal way.
The specific embodiment
Below in conjunction with Fig. 1, Fig. 2, introduce in detail safe clamping spanner of the present utility model, it comprises that wrenching bar 1 is connected with this wrenching bar one end and stretches into the driving end 2 in chuck fastener hole, the wrenching bar other end is provided with handle 3, in wrenching bar, opened along its length through hole 4, this through hole extends to described driving end, in through hole, be provided with slide bar 5 and spring 6, spring one end is connected with slide bar, and the other end is connected with the limit plunger 7 in being installed in through hole.As preferably, described through hole is step through-hole, the hole, small-bore 41 of this step through-hole extends to described driving end, the described slide bar sliding along this hole is installed in hole, described small-bore, driving end is stretched out in this slide bar one end, the other end is connected with slide bar head 8, and slide bar head is resisted against on the step surface 42 of described step through-hole; In the hole, large aperture 43 of step through-hole, described spring and limit plunger are installed, one end is resisted against on slide bar head described in spring; In implementation process, the one end away from driving end in hole, large aperture is provided with internal thread 44, and described limit plunger, by internal thread precession through hole, is easy for installation and removal.
The utility model course of work is as follows: when each component processing installs while not working, slide bar stretches out driving end under the pressure of spring; When clamping work pieces operates, driving end stretches in fastener hole, and slide bar moves along step through-hole under handle effect, thereby retreats in step through-hole, now can not affect the clamping work of spanner; After completing clamp operation, as long as operating personnel's thrust one removes, under the effect of spring, slide bar auto-extending driving end, and then promote driving end and shift out in chuck fastener hole, thus avoid the generation of security incident.
Above-mentioned embodiment is only for illustration of the utility model, and be not to restriction of the present utility model, the those of ordinary skill in relevant technologies field, in the situation that not departing from the utility model spirit and scope, can also make various variations and modification, therefore all technical schemes that are equal to also should belong to category of the present utility model.
