Abstract
The invention relates to a multi-specification adjustable fingerlike chuck comprising a chuck body, a fulcrum seat, a guide rod for the fulcrum seat, a press ring, a seat board, a pin roll for a fixed press claw, the fixed press claw, guide rods for the fixed press claw, a guide base, a section positioning block and a central positioning accessory. The multi-specification adjustable fingerlike chuck is characterized in that a sliding chute is arranged on the fulcrum seat, equally spaced screw holes and pin holes are arranged in the seat board, and the pin roll for the fixed press claw is installed in the sliding chute of the fulcrum seat. The multi-specification adjustable fingerlike chuck has the advantages that: firstly, as the sliding chute is arranged on the fulcrum seat, the fixed press claw can move freely in the sliding chute and can be inwards or outwards adjusted through the screw holes and the pin holes equally spaced in the seat board, thereby realizing multi-position installation; and secondly, under the action of the two guide rods for the fixed press claw, the fixed press claw clamping the end of a workpiece can deflect in the process of clamping or loosening, thereby leading the installation of the workpiece to be convenient.

Along with the fast development of world car industry, in light weight, the good heat dissipation of aluminium alloy rim, advantage such as attractive in appearance constantly approved, makes the sharp increase of aluminium alloy car wheel rim demand.For working (machining) efficiency, quality and the yield rate that improves aluminium alloy wheel hub, adopt numerically controlled lathe to join the processing of automation finger-like chuck to aluminium alloy rim, to improve working (machining) efficiency, quality, the yield rate of product.Existing finger-like chuck, as shown in Figure 1, cup 3 and pressure ring 4 are formed and comprise disk body 1, fulcrum block 5, fulcrum block guide post 2, seat board 6, fixing press claw bearing pin 12, fixing press claw 8, fixing press claw guide post 11, guide base 10, section locating piece 9, centralized positioning annex 7, drawn to its primary structure.Described disk body 1 is a clamping connector between chuck body and lathe, and its function is to be screwed on the machine tool chief axis 14 after the finger-like chuck is located by accurate face of the weak point on the disk body 1 and big transverse plane; Describedly draw cup 3, pressure ring 4 is connected with lathe oil cylinder pull bar 13 by high-strength screw, makes the pushing away of oil cylinder, stretching line move and pass to fulcrum block 5, fulcrum block 5 is realized rectilinear motion under fulcrum block guide post 2 acts on; Guide base 10 is fixed on the seat board 6, fixing press claw 8 is installed on fulcrum block 5 and the guide base 10 by fixing press claw bearing pin 12, fixing press claw guide post 11, the rectilinear motion of fulcrum block 5 is passed to fixing press claw 8, realize clamping and loosening up processing work 15; Section locating piece 9 is fixed on the guide base 10, and its function is to realize the plane positioning of workpiece; Centralized positioning annex 7 is installed on the seat board 6, and its function is when clamping workpiece, and is consistent by the centre of gyration of 3 or determined workpiece centre of multiple spot and anchor clamps.The wheel rim of every kind of specification of this finger-like chuck is equipped with the tight annex of a cover locating, when the debugging frock is produced in thread-changing, needing the location on the finger-like chuck is clamped accessory replacing is the location clamp fitting of corresponding production specification aluminium alloy rim, the waste in man-hour that causes frock to change and adjust, and improved the frock cost, cause the confusion of frock library management.
Summary of the invention
The objective of the invention is to, at above-mentioned deficiency, provide a kind of usefulness one cover locating tight annex, by adjusting, can realize the processing request of many specifications wheel rim, improve the work efficiency of thread-changing in the aluminium alloy car wheel rim class revolution process component process, save the frock cost, reduce the frock stock and be convenient to management.
In order to reach above purpose, the present invention by the following technical solutions, a kind of multi-specification adjustable fingerlike chuck, comprise disk body, fulcrum block, fulcrum block guide post, draw cup, pressure ring, seat board, fixing press claw bearing pin, fixing press claw, fixing press claw guide post, guide base, section locating piece and centralized positioning annex, it is characterized in that: described fulcrum block is provided with chute, described seat board is provided with equidistant screw and pin-and-hole, and the pin-and-hole that the fixing press claw bearing pin passes fixing press claw is installed in the chute of fulcrum block.
Advantage of the present invention is: the one, because fulcrum block is provided with chute,, cooperate equidistant screw and pin-and-hole on the seat board again in chute so fixing press claw can move freely, and just can on seat board, inwardly or outwards adjust, the realization multistation is installed; The 2nd because the fixing press claw guide post has two, clamp, fixing press claw has the beat action during clamping work pieces end under the effect of two guide posts in the loosening up process, facilitates the installation of workpiece like this.
