Description
Technical field
The utility model relates to a kind of clamping tool, particularly a kind of sheet part clamping tool.
Background technology
Processing one group of shape, size, material, technical requirement identical thin rounded flakes class part is often run in production.The cylindrical that particularly, concentricity tolerance high for machining accuracy is strict and endoporus are the technical barriers of a mechanical processing process always.In actual production, if the part of processing high-hardness material, this problem is more outstanding.Sheet parts shape and structure is simple, gauge is less, has difficulties in process for the clamping of part, turning, grinding, and during processing endoporus, benchmark is difficult to determine.
Turning attachment is a kind of device in order to clamping workpiece (with guiding cutter) on lathe.Its effect is by Workpiece fixing, to make workpiece obtain tram relative to lathe and cutter, and workpiece is reliably clamped.But when having machining accuracy to excircle of workpiece and endoporus and concentricity tolerance requirement is higher, traditional clamping tool just can not be satisfied the demand.
Therefore, one not only can play fixation to sheet part, can also have and become the key of dealing with problems compared with the sheet part clamping tool of high manufacturing accuracy and concentricity tolerance.
Utility model content
The purpose of this utility model is to provide one not only can play fixation to sheet part, can also have the sheet part clamping tool compared with high manufacturing accuracy and concentricity tolerance.
For achieving the above object, the utility model adopts following technical scheme, and a kind of sheet part clamping tool, comprising: chuck body, and chuck body is symmetrical about central shaft,
Positioning baffle, and the side being arranged on chuck body, be provided with the first through hole in the center of positioning baffle;
Elastic clip glassware, and be arranged on the opposite side of chuck body, the excircle of elastic clip glassware has the tapering matched with chuck body, the excircle of elastic clip glassware is provided with symmetrical many crack structures, material bin is provided with near one end of chuck body at elastic clip glassware, be provided with material folding locking end cap at the offside of material bin, and for fixing, workpiece fixed;
Limit material positioning sleeve, embeds chuck body inner, and is arranged between positioning baffle and elastic clip glassware, is provided with material returned spring in the inside of limit material positioning sleeve, and for by the workpiece in material bin.
As preferred further, described first through hole, limit material positioning sleeve and elastic clip glassware are symmetrical about chuck body central shaft.
As preferred further, described material returned spring is symmetrical about chuck body central shaft.
As preferred further, described material bin is symmetrical about chuck body central shaft.
As further preferably, lock between end cap at described material bin and material folding and be provided with material folding spring.
As preferred further, described material folding spring is symmetrical about chuck body central shaft.
As preferred further, described material folding spring is conical helical spring.
As preferred further, described material returned spring is cylindrically coiled spring.
As further preferably, be provided with the second through hole in the center of material folding locking end cap.
As preferred further, described second through hole is symmetrical about chuck body central shaft.
The beneficial effects of the utility model are: 1, can either effectively be fixed to workpiece and can ensure that the workpiece after processing has comparatively high manufacturing accuracy and concentricity tolerance; 2, sheet part is avoided to damage due to unbalance stress in process; 3, deft design, structure is simple, easy to operate, reliable clamping, and production cost is low, and applicability is wide, and part crudy is good, production efficiency is high, good in economic efficiency.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of sheet part clamping tool of the utility model.
In figure: chuck body 1, positioning baffle 2, material returned spring 3, limit material positioning sleeve 4, elastic clip glassware 5, material folding spring 6, material folding locking end cap 7, material bin 8, the first through hole 9, second through hole 10.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of sheet part clamping tool, comprising: chuck body 1, and chuck body 1 is symmetrical about central shaft.Positioning baffle 2, and the side being arranged on chuck body 1, be provided with the first through hole 9 in the center of positioning baffle 2.Elastic clip glassware 5, and be arranged on the opposite side of chuck body 1, the excircle of elastic clip glassware 5 has the tapering matched with chuck body 1, the excircle of elastic clip glassware 5 is provided with symmetrical many crack structures, material bin 8 is provided with near one end of chuck body 1 at elastic clip glassware 5, material folding locking end cap 7 is provided with at the opposite side of elastic clip glassware 5, the center of material folding locking end cap 7 is provided with the second through hole 10, lock between end cap 7 at material bin 8 and material folding and be provided with material folding spring 6, material folding spring 6 is conical helical spring, and is fixed by workpiece for fixing.Limit material positioning sleeve 4, embeds chuck body 1 inner, and is arranged between positioning baffle 2 and elastic clip glassware 5, and be provided with material returned spring 3 in the inside of limit material positioning sleeve 4, material returned spring 3 is cylindrically coiled spring, and for by the workpiece in material bin 8.
Positioning baffle 2, first through hole 9, limit material positioning sleeve 4, material returned spring 3, material bin 8, material folding spring 7, second through hole 10 and elastic clip glassware 5 are symmetrical about chuck body 1 central shaft.
In use, first choose the sheet parts that one group of cylindrical is processed, grinding is qualified, then organize the gauge sum of sheet parts according to this, select suitable limit material positioning sleeve 4, again this group part is loaded in elastic clip glassware 5, guarantee that this group sheet parts just loads.Then the material folding locking end cap 7 tightened with reinforced spring 6 is rotated with special spanner, in the process of tightening material folding locking end lid 7, because material folding locking end cap 7 promotes elastic clip glassware 5 and moves to the direction of chuck body 1, elastic clip glassware 5 excircle has tapering, at the inner surface of chuck body 1, also there is identical tapering, when elastic clip glassware 5 moves to the direction of chuck body 1, owing to being provided with symmetrical multi-seam structure at the excircle of elastic clip glassware 5, elastic clip glassware 5 can produce uniform symmetric shrinkage, clamp this thus and organize sheet parts to be processed, the accurate position assurance technological datum with regard to outer circle like this, so that turning, inner hole grinding.Turning, grinding tool enter in material bin 8 by the first through hole, workpiece is carried out to the turning of inner circle, chip under turning has the second through hole to discharge, after inner hole grinding reaches precision, unclamp material folding locking end cap 7, positioning baffle 2 and material returned spring 3, release the qualified workpiece of processing.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
