Description

The multistation clamping device of adjustable gripping power
Technical field
The utility model relates to pin process technology, is specifically related to a kind of multistation clamping device of adjustable gripping power.
Background technology
Pin is mainly used as assembling and positioning, also can be used as connecting.The type of pin has straight pin, taper bolt, pin with split pin hole, split pin and safety pin etc.Wherein with straight pin and taper bolt comparatively conventional.Straight pin utilizes micro-interference to be fixed in pin-and-hole in use.Straight pin is divided into general cylindrical pin, cylindrical pin with internal thread, cylindrical pin with external thread, pin with split pin hole, elastic cylindrical pin etc.The processing of cylindrical pin with internal thread comprises bores endoporus, tapping thread and end face milling and cylindrical.Above-mentioned technique all needs clamping device internal threads straight pin to position.Often there is following problem in the clamping device at present for cylindrical pin with internal thread boring: 1. once can only clamp a workpiece, make the drilling efficiency of cylindrical pin with internal thread low; 2. clamping force cannot regulate, if clamping force is excessive, easily damages the presentation quality of cylindrical pin with internal thread, as caused impression etc.
Utility model content
The utility model provides a kind of multistation clamping device of adjustable gripping power, and once can only clamp a workpiece to solve existing clamping device, efficiency is low, and the problem that clamping force can not regulate.
The utility model scheme is as follows: the multistation clamping device of adjustable gripping power, comprise base, base is fixed with brace table, both sides base being positioned at brace table are respectively equipped with left locating piece and right locating piece, the side that left locating piece is relative with right locating piece has the identical Workpiece fixing groove of two structures, the notch level of two Workpiece fixing grooves is relative, the table top of brace table is concordant with the lower wall of Workpiece fixing groove, wherein, left locating piece is fixed on base, right locating piece can slide on base, the right locating piece dorsad side of left locating piece and one end of holddown spring is fixed, the other end of holddown spring is fixed on nut, nut thread connects on the guide bar, guide post is fixed on base.
This programme operation principle is as follows: when left locating piece and right locating piece separate, cylindrical pin with internal thread can be put into successively two Workpiece fixing grooves, then nut is rotatably compressed, clamp nut is advanced, gradually reduce holddown spring, holddown spring force right locating piece gradually near left locating piece until clamp each workpiece.Wherein the workpiece at middle part is by brace table support, and is pushed against by other workpiece of both sides.
The utility model can clamp multiple workpiece by the cooperation of brace table and two Workpiece fixing grooves simultaneously, and by the adjustable thrust of holddown spring, can not because thrust is excessive the outer surface of defective work piece.
Further, be provided with left limit plate in the Workpiece fixing groove of left locating piece, the bottom land of Workpiece fixing groove has pilot hole, is equipped with push rod in pilot hole, and the inner and the left limit plate of push rod are fixed.Hold out against left limit plate by push rod, left limit plate holds out against the cylindrical of cylindrical pin with internal thread, can guarantee that location is more stable.
Further, the Workpiece fixing groove internal fixtion of right locating piece has right limit plate.The cylindrical pin with internal thread of right limit plate to right side plays spacing effect.
Further, side direction base being positioned at guide post is provided with for the spacing limited block of nut, and guide post is fixed on limited block.Limited block plays spacing effect to clamp nut, and limited block is used for fixed guide pole simultaneously, and structure is simpler, and saves material.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: left locating piece 1, cylindrical pin with internal thread 2, right limit plate 3, right locating piece 4, holddown spring 5, nut 6, guide post 7.
As shown in Figure 1: base is fixed with brace table, both sides base being positioned at brace table are respectively equipped with left locating piece 1 and right locating piece 4.The side that left locating piece 1 is relative with right locating piece 4 has the identical Workpiece fixing groove of two structures, and as shown in Figure 1, the present embodiment show only the situation clamping two cylindrical pin with internal threads 2 in two Workpiece fixing grooves.The bottom land of Workpiece fixing groove is V-shaped, and the notch level of two Workpiece fixing grooves is relative, and the table top of brace table is concordant with the lower wall of Workpiece fixing groove.
Left limit plate is provided with in the Workpiece fixing groove of left locating piece 1, the bottom land of Workpiece fixing groove has pilot hole, push rod is equipped with in pilot hole, the inner and the left limit plate of push rod are fixed, the locking mode of push rod, can arrange external screw thread in the outer end of push rod, and by pad and locking nut locking, also the piston rod of cylinder can be directly made to drive push rod, to realize efficient action.The Workpiece fixing groove internal fixtion of right locating piece 4 has right limit plate 3.
Left locating piece 1 is welded on base, and right locating piece 4 can slide on base, and base can arrange chute, and right locating piece 4 slides in chute, to play the effect of limit slippage track.The right locating piece 4 dorsad side of left locating piece 1 and one end of holddown spring 5 is fixed, the other end of holddown spring 5 is fixed on nut 6, nut 6 is threaded on guide post 7, side direction base being positioned at guide post is provided with for the spacing limited block of nut, guide post is fixed on limited block, base top has escape groove, rotates smoothly to enable nut.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
