Abstract

The utility model discloses a kind of glass bar and automatically adjust compression chuck, comprise the base cover and be threadedly connected to together tightly to overlap, a cuff is provided with in described tight cover, the outside surface of described cuff is provided with and somely makes himself yielding with the pretension groove shrinking internal diameter, the end lateral border of described cuff is provided with an outslope face, the tip inside edge of described tight cover is provided with slope in matching with described outslope face.Insert glass bar in chuck after, actual glass bar inserts in cuff, will tightly overlap inside extruding, because of base cover, all adopts slope to coordinate between tight cover and cuff, causes cuff to be out of shape and steadily clamp glass bar to shrink internal diameter.Automatic tune degree of tightness principle: time cuff put into by glass bar, cuff is entered inside, such two slopes are frustrated tightly, firmly pin glass bar, when needs take out glass bar time, cuff is walked toward outside, such two slopes are frustrated wide, and glass bar can easily take out.

Description

Glass bar adjusts compression chuck automatically

Technical field

The utility model relates to Crystal ornaments processing technical field, is more particularly that a kind of glass bar adjusts compression chuck automatically.

Background technology

The processing principle of conventional Crystal ornaments: clamping glass bar with pliers and deliver on stove fire and heat, then sending in die hole by the part of scissors clip glass stick stub bar portion through heating post softening, namely shaping after matched moulds.

Disclosed in its Patent CN201420160900.8, a kind of Crystal ornaments production machine is exactly the design made based on above-mentioned ultimate principle, its content comprises smelting furnace, sheared blank device, corresponding circular rotating worktable, described circular rotating worktable is provided with equally distributed some pressing molds ringwise, described some pressing molds include the pressing mold of two or equally distributed symmetrical multiple material feedings, the pressing mold of each material feeding is respectively equipped with corresponding injecting device, each injecting device has corresponding described sheared blank device respectively by the conveying expanding channels of mutual equal length, described some pressing molds comprise mutually corresponding upper and lower mould respectively, the pressing mold of described material feeding and the counterdie of wherein 2 to 3 pressing molds be positioned at thereafter are respectively equipped with corresponding nib, correspond respectively to the described counterdie being provided with nib and be provided with punching device.

Glass stick feed collet head in above-mentioned conventional Crystal ornaments production unit has following defect: it is in kind that loose or dislocation easily occurs after capturing glass bar chuck, causes glass bar to be broken, cause waste.

Utility model content

The purpose of this utility model is to overcome the above defect of prior art, provides the glass bar that a kind of structure is simple, crawl firmness by force, not easily loosens automatically to adjust compression chuck.

In order to reach above object, the utility model is achieved through the following technical solutions: a kind of glass bar adjusts compression chuck automatically, it is characterized in that, comprise the base cover and be threadedly connected to together tightly to overlap, a cuff is provided with in described tight cover, the outside surface of described cuff is provided with and somely makes himself yielding with the pretension groove shrinking internal diameter, the end lateral border of described cuff is provided with an outslope face, the tip inside edge of described tight cover is provided with slope in matching with described outslope face.

Insert glass bar in chuck after, actual glass bar inserts in cuff, touch inducing switch will tightly overlap inside extruding by being placed in outside cylinder by a push rod, Yin Ji cover, tight overlapping all adopt slope to coordinate between cuff, cause cuff to be out of shape and steadily clamp glass bar to shrink internal diameter.

The design of these two slopes and pretension groove, be not only and can meet the demand, the more important thing is that its object is from main regulation Zhang Jindu: time glass bar puts into cuff (namely loading), cuff is entered inside, and such two slopes are frustrated tightly, firmly pins glass bar, when needs take out (namely unloading bar) glass bar time, cuff is walked toward outside, and such two slopes are frustrated wide, and glass bar can easily take out.

As preferably, the length of described interior slope will be longer than the length in described outslope face.

Cuff external diameter with tightly overlap the matched situation of internal diameter, if frustrate wide, only have when interior slope length is longer than outslope face, both just have the displacement of frustrating mutually and moving, and the length of above-mentioned two slopes can only design and could not realize length not etc. in the size of obliquity.Frustrate and tightly then do not need because there is the internal diameter of cuff can deformation.

As preferably, every bar pretension groove runs through its place cuff and is provided with the one end in outslope face but does not run through the other end.

Pretension groove runs through one end and does not run through the other end, then conveniently can design many pretension grooves, certainly we also can design the pretension groove running through two ends, but such pretension groove can only design one, no person's cuff is just divided into two independently semilunar plates, assembling is just inconvenient, and the deformation difficulty of a pretension groove is slightly larger.

As preferably, run through cuff and be three with the pretension groove of one end and wait radian pitch arrangement.

Article three, namely the radian pitch arrangement such as pretension groove, be also positioned at three summits of equilateral triangle viewed from cross section, although a problem that just can solve deformation, three are more prone to realize deformation, more numbers then self toughness is just poor.

Beneficial effect: insert glass bar in chuck after, actual glass bar inserts in cuff, touch inducing switch will tightly overlap inside extruding by being placed in outside cylinder by a push rod, Yin Ji cover, tight overlapping all adopt slope to coordinate between cuff, cause cuff to be out of shape and steadily clamp glass bar to shrink internal diameter.
