Abstract
The invention discloses a cramping device, and in particular relates to an automatic positioning cramping mechanism for machine tooling equipment, which comprises a cramping body. The mechanism is characterized in that a hydraulic cylinder is fixed on the cramping body; a piston rod matched with the hydraulic cylinder is connected with a gripper body; the cramping body is provided with a positioning pin roll which is parallel to the piston rod; the outer end of the positioning pin roll is inserted into a hole on the gripper body and extends out; and a spring is arranged between the positioning pin roll and the gripper body, and is supported against the positioning pin roll downwards. When the cramping mechanism works, a work piece placed on a workbench drives the piston rod through the hydraulic cylinder, and the gripper body presses the work piece; previously, the positioning pin roll supported against by the spring is firstly inserted into the hole on the work piece for positioning to achieve linkage of positioning and cramping, and accurate, reliable and firm assembly, thereby improving the processing precision of the work piece.
Description
Technical field
The present invention relates to a kind of clamping device, particularly a kind of automatic positioning cramping mechanism that is used on the machining apparatus.
Background technology
Need special clamping tool when the machined for some special workpieces,, have long size after the casting in the vertical, need its clamping is fixed on the platen, carry out milling cutting then, be divided into a plurality of as pedestal cap.Clamping need position and cramping fixedly the time, and clamping mechanism location commonly used at present and cramping can not be interrelated and be linked, troublesome poeration, and the fastness of accurate positioning and clamping workpiece is poor.
Summary of the invention
The purpose of this invention is to provide strong, accurate firm, the reliable automatic positioning cramping mechanism of flexible movements of a kind of location cramping linkage, overcome the deficiencies in the prior art.
Automatic positioning cramping mechanism of the present invention comprises clamp body 4, it is characterized in that: be fixed with hydraulic jack 9 on clamp body 4, the piston rod 10 that matches with hydraulic jack 9 connects paw body 7; Be provided with the alignment pin 6 that parallels setting with described piston rod 10 on clamp body 4, the outer end of alignment pin 6 is inserted in the hole on the paw body 7 and is stretched out, and is provided with spring 3 and leans alignment pin 6 downwards between alignment pin 6 and clamp body 4.
Automatic positioning cramping mechanism of the present invention, be inlaid with fairlead 2 on the wherein said clamp body 4, described alignment pin 6 is inserted in the fairlead 2, has been threaded at the upper port place of fairlead 2 to adjust screw plug 1, and described spring 3 is located to be adjusted between screw plug 1 and the alignment pin 6.
Automatic positioning cramping mechanism of the present invention is processed with slotted hole on the wherein said alignment pin 6, and spacer pin 5 passes slotted hole and two ends is fixedlyed connected with fairlead 2.
Automatic positioning cramping mechanism of the present invention, wherein said paw body 7 and alignment pin 6 are two groups and are symmetrical arranged with respect to described piston rod 10.
Join by pin 12 that is threaded with piston rod 10 and the spheric washer 11 that is enclosed within on the pin 12 between the automatic positioning cramping mechanism of the present invention, wherein said piston rod 10 and paw body 7.
Automatic positioning cramping mechanism of the present invention, place the workpiece 13 on the workbench to press to workpiece 13 during work by hydraulic jack 9 drive piston rods 10, paw body 7, leaning alignment pin 6 by spring before this inserts in the hole on the workpiece 13 in advance and positions, reach the interlock of location and cramping, accurately and reliably, clamping is firm, has improved the machining accuracy of workpiece.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
The specific embodiment
As shown in Figure 1: 4 is the anchor clamps bases, be bolted to connection the hydraulic jack 9 that joins with hydraulic control device at the middle part of clamp body 4, the termination of the piston rod 10 that matches with hydraulic jack 9 is set with spheric washer 11 and is used for eliminating the skew that paw body 7 produces at course of action by threaded pin 12 intrinsic paw bodies 7 on pin 12.Parallel with the axis of piston rod 10 on clamp body 4 and be provided with alignment pin 6, alignment pin 6 is positioned at fairlead 2, has been threaded at the place suitable for reading of fairlead 2 to adjust screw plug 1; In the upper end of alignment pin 6 and adjust between the screw plug 1 and be provided with spring 3; Be processed with slotted hole on alignment pin 6, spacing bearing pin 5 places in this slotted hole and two ends are fixed in the hole on the fairlead 2, is used for alignment pin 6 axially movable spacing.The lower end of bearing pin 6 is inserted in the hole on the paw body 7 and is stretched out.Fixedly being inlaid with briquetting cover 8 on the bottom surface of paw body 7 is used for contacting with workpiece.Above-mentioned paw body 7 and alignment pin 6 are two groups and are symmetrical arranged with respect to piston rod 10.
During work, workpiece 13 places on the workbench of lathe, drive hydraulic jack 9 work by hydraulic control device, piston rod 10 drives paw body 7 and moves downward, and alignment pin 6 moves down under the effect of spring 3 thereupon, earlier by positioning in the hole on the alignment pin 6 insertion workpiece 13, thereupon by paw body 7 cramping workpiece 13, location and cramping are interrelated, and flexible movements are reliable, accurately firmly.
