Description
Technical field
The utility model relates to a kind of anchor clamps, particularly a kind of anchor clamps that are used for the hinge deep hole on the broach(ing) machine.
Background technology
At present, clamping situation to workpiece when cutting with scissors deep hole usually on broach(ing) machine is: clamp body is connected with the I-shaped groove of machine tool dragging plate by fastening bolt, the gear shaft engagement of installing on the internal tooth thimble axle of the band tooth bar of installing on the clamp body and the top board, cover one compression spring on the internal tooth thimble axle.Axially move the back by drive the internal tooth thimble with spanner turning gear wheel shaft during clamping workpiece, prop up the fixedly thimble of machine tool dragging plate when workpiece one end, after the other end is inserted in the interior perforation of internal tooth thimble axle, unclamp spanner, internal tooth thimble axle is moved forward under the spring force effect of compression spring, with fixing thimble from two ends with Work-sheet pressing.Because workpiece is to be fixed by the compression spring force that spring produces that is enclosed within on the internal tooth thimble axle, again because internal tooth thimble axle moves forward and backward distance not quite, after clamp body is adjusted to certain position, just define the length of workpiece, long can not clamping, too short then clamping shakiness, so the length of workpiece directly influences the crudy of workpiece, add in enormous quantities man-hour to the required precision of Workpiece length than higher.And being the tension force that relies on the compression spring because of workpiece compresses the end face of workpiece, and clamp body can only move in the I-shaped groove scope on planker, and the length of check and correction processing work is very restricted.And, because workpiece one end need insert in the interior perforation of internal tooth thimble axle,, the diameter of workpiece just must change internal tooth thimble axle so changing, so just need to be equipped with the internal tooth thimble axle of different-diameter, increase the anchor clamps cost thus, increase operational sequence, the cost of converted products is improved.
Summary of the invention
The purpose of this utility model provides a kind of anchor clamps that are used for the hinge deep hole on the broach(ing) machine, and it must not change the workpiece that anchor clamps just can clamp different length, different-diameter by the radially clamping of workpiece to the hinge deep hole.
The purpose of this utility model is achieved in that the clamp body upper end is fixedly connected with the top board that is provided with at least one via hole, it is characterized in that: clamp body is provided with at least one groove, the wall of described groove is provided with chute, the fixture block of two band screws is arranged in groove and is slidingly matched with chute, two fixture blocks cooperate respectively by the opposite screw thread of two sections rotation directions that is provided with on screw and the screw rod, the top of screw rod is provided with and is used for spacing structure, via hole and handle set that top board is passed in the upper end of screw rod are fixedly connected to form axial location, the fixedly connected front pressuring plate that is provided with at least one through hole of clamp body front end, its through hole is facing to two residing positions of fixture block.
The abutting end of described two fixture blocks is respectively equipped with corresponding minor arc groove.
The spacing structure that is used for that described screw rod top is provided with is the back-up ring of fixedlying connected with screw rod.
Owing to adopted said structure, clamp body is connected with the I-shaped groove of machine tool dragging plate by fastening bolt, the fixture block of two band screws is arranged in the groove that is provided with on the clamp body and is slidingly matched with chute on the cell wall, two fixture blocks cooperate respectively by the opposite screw thread of two sections rotation directions that is provided with on screw and the screw rod, the via hole that top board is passed in the upper end of screw rod is fixedlyed connected with handle set, the spacing structure that is used for that the top of screw rod is provided with is positioned at the top board below, screw axial is positioned on the top board, front pressuring plate is fixedly connected on the clamp body front end, two fixture blocks are kept off in the groove of clamp body, from just or the counter-rotation handle set, drive two fixture blocks by screw rod and under the guiding of chute, move.Because two threaded engagement that fixture block is opposite with rotation direction on the screw rod separately, so two fixture blocks separate or draw close along thread rotary orientation opposite on the screw rod respectively under the guiding of chute when screw rod rotates, in order to clamping workpiece.The minor arc groove of the correspondence that the abutting end of two fixture blocks is provided with respectively can be with workpiece from radially tightly clamping.The through hole that is provided with on the front pressuring plate is used for passing of workpiece.
The utility model is simple in structure, make the clamping of workpiece of the hinge deep hole on broach(ing) machine convenient, more firm, and need not change anchor clamps and just can carry out clamping the workpiece of different length, different-diameter, enlarged the scope of application of equipment, can reduce production costs.
Be described further this use is novel below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the present utility model;
Fig. 2 be Fig. 1 local A-A to cutaway view Amplified image.
The specific embodiment
Fig. 1 is the clamp structure schematic diagram of the hinge deep hole that is used with six broach(ing) machines.Referring to Fig. 1, Fig. 2, clamp body 1 upper end is screwed and is connected with the top board 2 that is provided with six via holes, equidistantly on the clamp body 1 be provided with six grooves 9, be equipped with chute on the same distolateral wall of each groove 9, six via holes on the top board 2 are the chute on the corresponding clips concrete 1 respectively.Be equipped with the fixture blocks 7,8 of two band screws in each groove 9, the chute on fixture block 7,8 and the cell wall is slidingly matched, and cooperates respectively by the opposite screw thread of two sections rotation directions of setting on screw and the screw rod 5.The abutting end of two fixture blocks 7,8 is respectively equipped with corresponding minor arc groove, is used for holding workpiece.The top of screw rod 5 is provided with and is used for spacing structure, and this is used for spacing structure for be fixedly connected on the back-up ring 6 on the screw rod 5 with pin 10.The via hole that top board 2 is passed in the upper end of screw rod 5 is fixedlyed connected by pin 11 with handle set 4, and handle set 4 and back-up ring 6 make screw rod 5 axial location on top board 2, and the upper end of screw rod 5 and top board 2 matched in clearance can be rotated screw rod 2 in via hole.Clamp body 1 front end is screwed the front pressuring plate 3 that is connected with six through holes 12, and in groove 9 and be limited on the chute, each through hole 12 is facing to two fixture block 7,8 residing positions with fixture block 7,8 retaining.
