Abstract

The invention discloses a spiral linkage centering clamping device and relates to a centering clamping device. The spiral linkage centering clamping device comprises a left linkage mechanism, a right linkage mechanism and a base for the linkage mechanisms to be arranged in, wherein the left linkage mechanism and the right linkage mechanism are symmetrically arranged. Each linkage mechanism comprises a screw, a wedge-shaped block connected onto the screw in threaded mode, a transverse clamping jaw and a vertical rod arranged between the transverse clamping jaw and the wedge-shaped block. The lower end and the upper end of the vertical rod are respectively in wedge surface matching with the inclined surface of the wedge-shaped block and the driving end of the transverse clamping jaw, and the driven end of the transverse clamping jaw is used for clamping workpieces. The driven ends of the two transverse clamping jaws and the inclined surfaces of the wedge-shaped blocks arranged in the left linkage mechanism and the right linkage mechanism are oppositely arranged, the rotating directions of the two screws are reverse, the two screws are connected through a ball coupler, and a handle is connected outside one screw. Each linkage mechanism further comprises a reset elastic sheet, one end of the reset elastic sheet is fixedly arranged on the base, and the other end of the reset elastic sheet is fixedly arranged on the driven end of each transverse clamping jaw. The spiral linkage centering clamping device overcomes the defects of the complex structure and infirm clamping, and improves efficiency.

Description

A kind of spiral interlock centering clamping device
Technical field
Clamping device technical field, particularly a kind of spiral interlock centering clamping device the present invention relates to feel relieved.
Background technology
At present centering and clamping apparatus a large amount of use in machining, clamping device is that the workpiece of having good positioning is fixed on the setting element in whole process reliably, and the mechanism that changes of occurrence positions not.When clamping work pieces, do not allow to destroy the location of workpiece, and enough rigidity should be arranged, guarantee necessary clamping force, but should not damage the workpiece machined surface or make workpiece produce distortion, thereby guarantee machining accuracy.Because the outer surface of most of workpiece need to be processed, for the ease of the processing of lathe to workpiece, present clamping device complex structure, and operation is comparatively inconvenient, be difficult to the workpiece clamping of feeling relieved, or centering clamp firm not, the poor effect that its centering is clamped, greatly reduce working (machining) efficiency, larger impact is played in production.
Summary of the invention
The invention provides a kind of simple in structurely, workpiece is easily clamped, clamp firmly worm drive centering and clamping apparatus.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of spiral interlock centering clamping device, comprise symmetrically arranged left and right link gear and the pedestal that is installed with described link gear, wherein each link gear comprises a screw rod, is threadedly connected to a wedge, a horizontal jaw on the screw rod, is located at the vertical bar of one between horizontal jaw and the wedge, the lower end of this vertical bar cooperates with the inclined-plane of wedge, the drive end wedge surface of horizontal jaw respectively with the upper end, and laterally the driven end of jaw is used for holding workpiece;
The driven end of two horizontal jaws in the left and right link gear, the inclined-plane of wedge all arrange in opposite directions, and two screw rod rotation directions connect on the contrary and by ball coupling, and one of them screw rod is circumscribed with handle;
Described link gear also comprises reseting shrapnel, and this reseting shrapnel one end is installed on the pedestal, and the other end is installed on the driven end of horizontal jaw.
Beneficial effect: the present invention is simple in structure, drives two vertical rods and two beam movement by two halfnuts, to the workpiece clamping of feeling relieved, easily to the workpiece clamping of feeling relieved, and the axially symmetric structure that adopts, two two cross bars clamp workpiece, clamping firmly.
Description of drawings
Fig. 1 is the schematic diagram of spiral interlock centering clamping device embodiment of the present invention.
The specific embodiment
Shown in Fig. 1, a kind of worm drive centering and clamping apparatus of the present invention, comprise a symmetrically arranged left side, right link gear and the pedestal 1 that is installed with described link gear, wherein each link gear comprises a screw rod, be threadedly connected to the wedge 2 on the screw rod, one horizontal jaw 9, be located at the vertical bar 6 between horizontal jaw 9 and the wedge 2, the lower end of this vertical bar 6 and upper end respectively with the inclined-plane of wedge 3, laterally the drive end wedge surface of jaw 9 cooperates, laterally the driven end of jaw 9 is used for holding workpiece, left, the driven end of two horizontal jaws 9 in the right link gear, the inclined-plane of wedge 2 all arranges in opposite directions, left screw rod 5 is opposite with right screw rod 4 rotation directions also to be connected by ball coupling 12, right screw rod 4 is circumscribed with handle 3, described link gear also comprises reseting shrapnel 10, this reseting shrapnel lower end is fixed on the pedestal 1 by screw 8, and the upper end is installed on the driven end of horizontal jaw 9.Clockwise rotate bolt 3, left screw rod 5 and 4 beginnings of right screw rod are to the middle part horizontal movement, driving simultaneously two wedges 2 be threaded moves to the middle part, thereby driving two horizontal jaws 9 draws in mobile to the centre, workpiece 13 is clamped, also be provided with two caging bolts 11 on the pedestal 1, caging bolt 11 is inserted in two locating slots 7 that the middle part of two vertical rods 6 has, can avoid like this two vertical bars 6 excessively mobile, and so that two vertical bars 6 eject outside the groove; When taking off the workpiece 13 of clamping, because the driven end of two horizontal jaws 9 is provided with automatically retraction of 10, two horizontal jaws 9 of flat spring.
Above-described only is preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
