Description
Technical field
This utility model relates to a kind of fixture, particularly relates to the clamping device of a kind of circular end cap.
Background technology
Dish valve fitment has the circular end cap of a kind of sealing, for dish valve is sealed, for the ease of installing sealing ring, it is necessary at the milling slot on end face of end cap；When end cap is carried out groove milling, first need end cap is clamped, in order to have good self-locking performance when ensureing and end cap is clamped, now have employed helical clamping apparatus, namely realize the propelling in clamping face with bolt, workpiece is clamped, owing to bolt has good self-locking performance, so clamping effect is good；But helical clamping apparatus, adopt the characteristic that bolt drives, make clamping stroke excessive, so that clamping process is comparatively time-consuming, and in order to enable clamping force to balance, generally to adopt multiple bolt to drive, so bolt is tightened one by one when clamping workpiece, again workpiece is unclamped one by one during absent-mindedness workpiece so that clamping process complexity is tediously long.
Utility model content
This utility model is intended to provide a kind of dish valve end cap clamping device, with the clamping mode that dish valve end cap is clamped by simplification, makes again fixture have self-locking performance simultaneously.
Base case dish valve end cap clamping device of the present utility model, including: base, locating piece and clamping section；Described clamping section includes clamping mounting seat, clamping block, linkage block, rotating shaft and handle；Described locating piece has a V-arrangement clamping face, and is bolted on described base；Described clamping mounting seat is fixedly mounted on described base, and described clamping block also has a V-arrangement clamping face, and clamping block is slidably connected with clamping mounting seat, and the V-arrangement clamping face of clamping block is relative with the V-arrangement clamping face of locating piece；Described rotating shaft and described clamping mounting seat are rotationally connected；Described handle is fixing with described rotating shaft to be connected；The two ends of described linkage block are hinged with described clamping block and described rotating shaft respectively, and the jointed shaft of described linkage block and described rotating shaft is fixed on the end face of described rotating shaft, and with described rotating shaft eccentric setting.
In this utility model, owing to rotating shaft is rotationally connected with clamping mounting seat, clamping block is slidably connected with clamping mounting seat, the face end of linkage block is hinged with rotating shaft and clamping block respectively, and the jointed shaft of linkage block and rotating shaft is eccentric with rotating shaft, so that clamping mounting seat, rotating shaft, clamping block and linkage block define slider-crank mechanism；Then turning handle makes axis of rotation, then can realize moving back and forth of clamping block, can realize clamping block and to the clamping of workpiece and unclamp；Having two dead points additionally, due to slider-crank mechanism, namely when two pin joints of spindle central Yu linkage block connect being aligned, if not by the effect of external force, slider-crank mechanism is up to stress balance；So this device is when clamping the workpiece of a certain class particular size, when namely making slider-crank mechanism be placed exactly in dead-centre position after clamping workpiece, this device has self-lock ability；Therefore this base case not only makes clamping mode simple, also makes have self-locking performance during clamping workpiece；And for clamping round piece, V-arrangement clamping face has the positioning action to workpiece.
Workpiece is lain between the V-arrangement clamping face of locating piece and clamping block；Turning handle makes axis of rotation just can realize the clamping to workpiece, thus simplifying the clamping mode to the clamping of dish valve end cap, makes again fixture have self-locking performance simultaneously.
Preferred version one, as the further optimization to base case, one end of described handle is provided with the collar, and the collar is sleeved on one end of rotating shaft, and described handle and described rotating shaft is fixed with pin；Handle and rotating shaft realize fixing by pin, the dismounting of favourable rotating shaft and handle and replacing.
Preferred version two, as the further optimization to base case, described clamping mounting seat is also provided with rotating shaft trip bolt；Due in the course of processing of workpiece, the interference that workpiece and fixture all can be given a shock so that loosening easily occurs in workpiece, therefore it is provided with rotating shaft trip bolt, the change of the power that balance vibrations produce；Owing to, in the vibrations process of workpiece, perturbed force is random change always, it is difficult to forming the accumulation of power, and perturbed force is all not too large, institute's trip bolt can eliminate perturbed force preferably.
Preferred version three, as the further optimization to base case, described locating piece is slidably mounted on described base, and is provided with fastening bolt on locating piece；Owing to the clamping stroke of slider-crank mechanism is limited, and in order to self-locking can be formed after clamping workpiece, so that this fixture is only capable of the workpiece of clamping one style number；In order to make this fixture have bigger use scope, locating piece and base are slidably connected, and fastening bolt is set, so that the position adjustable that locating piece is on base, thus meeting the clamping to different size workpiece.
Preferred version four, as the further optimization to base case, described clamping mounting seat is provided with chute and rotating shaft installing hole, and described clamping block is slidably mounted in chute, and chute is also provided with cover plate, and described cover plate is screwed in clamping mounting seat；Owing to clamping block needs to be slidably connected with clamping mounting seat, so this optimization is while the slip demand of satisfied clamping block, clamping block is also had good position-limiting action, and makes installation and removal convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model dish valve end cap clamping device embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
