Abstract
The invention relates to the field of clamping devices, in particular to an arc type clamping device. The arc type clamping device comprises a base, a positioning block, a stud, nuts and a clamping portion. The base comprises an upper base body and a lower base body. The positioning block is clamped to the upper surface of the upper base body. A workpiece is placed on the upper surface of the lower base body. The stud penetrates the positioning block to reach the lower base body and is arranged in the lower base body. The upper end of the stud is fixed to the upper surface of the positioning block through one nut. The lower end of the stud is fixed to the upper surface of the lower base body through another nut. The clamping portion is arranged on the lower surface of the upper base body and clamps the lower end of the positioning block and the stud. The other end of the clamping portion abuts against the workpiece. The clamping portion is matched with the lower surface of the upper base body, the lower end of the positioning block and the contact face of the stud. The arc type clamping device is simple in structure and simple in working principle.
Description
Technical field
The present invention relates to a kind of clamping device field, particularly relate to a kind of circular arc type clamping device.
Background technology
Be used for fixing processing object in machine-building process, make it to occupy correct position, to accept the device of constructing or detecting, also known as jig.In a broad sense, any operation in technical process, is used for rapidly, installs easily and safely the device of workpiece, all can be described as fixture.Such as weld jig, inspection jig, assembling jig, jig etc.Wherein jig is the most common, often referred to as fixture.On lathe during processing work, the dimensions reaching drawing for making the surface energy of workpiece and specify, geometry and with the technical requirements such as the relative-position error on other surfaces, must by Workpiece fixing, clamping before processing.
In existing Chinese patent document CN104057325AZ, provide a kind of bowl-shape Workpiece clamping device of bottom of which has holes, the cylinder comprising pedestal and be vertically fixed on pedestal, wherein, also be provided with post wedge, plunger, positioning screw and back-moving spring, described post wedge and pedestal are vertically slidably connected, the piston rod clamping of post wedge lower end and cylinder, and the circumference of upper end arranges inclined-plane; Described plunger is provided with the clamping limb of the bowl-shape workpiece inner wall coordinating bottom of which has holes, described post wedge both sides are equipped with described plunger, and plunger and pedestal are slidably connected, and plunger at one end coordinates with inclined-plane, post wedge upper end, the other end is connected with back-moving spring, and the described back-moving spring other end is connected on pedestal; Described positioning screw is axially set in the center of post wedge upper end along post wedge, and positioning screw upper end is provided with clamping nut.
The operation principle of the bowl-shape Workpiece clamping device of bottom of which has holes is: by opening down for the bowl-shape workpiece 7 of bottom of which has holes, and make positioning screw 5 insert in the hole of bottom, the bowl-shape workpiece 7 of bottom of which has holes compresses by positioning screw 5 upper end clamping nut, Compressed Gas is entered in control cylinder lower end, the piston rod 1 of cylinder protrudes upward, drive post wedge 2 moves, post wedge 2 promotes two plungers 4 laterally respectively to two plungers 4, the clamping limb 41 of two plungers 4 exerts a force from two positions that bowl-shape workpiece 7 inwall of bottom of which has holes is relative, thus the bowl-shape workpiece 7 of bottom of which has holes is clamped, back-moving spring 6 is compressed because of plunger 4, otherwise then unclamp workpiece.
The bowl-shape Workpiece clamping device of this bottom of which has holes, mainly by the relative motion between piston rod 1, drive post wedge 2, two plungers 4, back-moving spring 6 and positioning screw 5, clamping nut be fixedly connected with the clamping realized workpiece, its overall structure is more complicated, operation principle is more complicated.
Summary of the invention
The object of this invention is to provide a kind of structure simple, the simple circular arc type clamping device of operation principle.
The base case that this programme provides is: plant circular arc type clamping device, comprise pedestal, locating piece, stud and nut, pedestal comprises top base and bottom base, locating piece is stuck in the upper surface of top base, the upper surface of bottom base is provided with workpiece, stud runs through locating piece to bottom base and is arranged at bottom base inside, the upper end of stud is fixed on locating piece upper surface by nut, the lower end of stud is fixed on the upper surface of bottom base by nut, also comprise clamping part, clamping part is arranged at the lower surface of top base and the lower end of clamping position block and stud, the other end and the workpiece of clamping part offset, the lower surface of clamping part and top base, the lower end of locating piece, the contact surface of stud matches.
The operation principle of this programme is: the upper end of stud is fixed and realized by nut, connection between locating piece and top base, the lower end of stud is fixed and is realized by the connection of nut and bottom base, nut below can realize moving up and down of stud, when nut is below fixed, the nut turned above presses down locating piece, locating piece and clamping part are offseted, realizes the clamping to workpiece, otherwise then unclamp workpiece.
The effect that this programme reaches is: by pedestal, locating piece, stud, being interconnected between nut and clamping part, realize the clamping effect to different size workpiece, and its overall structure is simple, operation principle is also simple.
Preferred version one: based on the preferred version of scheme, the lower surface of described top base is provided with groove, described groove is set to arc-shaped, the contact surface of the lower surface of described clamping part and top base is set to the arc-shaped matched, one end of described clamping part and absorption surface is set to arc-shaped, promotes locating piece downwards and make clamping part stressed more even when nut is above tightened.
