Description
Technical field
The utility model relates to a kind of mechanical manufacturing field, more particularly, particularly relates to the soft pawl clamping device that a kind of soft pawl to oild chuck on numerically controlled lathe adds man-hour.
Background technology
In prior art, numerically controlled lathe generally carrys out holding workpiece with oild chuck.Oild chuck is all furnished with quenchless claw usually, and we are referred to as soft pawl.Soft pawl divides inner clamping type and the soft pawl of external clamping two kinds of forms, and when chuck closes, the soft pawl of clamping work pieces is the soft pawl of inner clamping type, and when chuck opens, the soft pawl of stretching workpiece is the soft pawl of external clamping.Be illustrated in figure 1 the soft pawl of oild chuck external clamping, soft pawl is located with end face teeth groove and master jaw, is fixed on master jaw by the T-nut in screw and master jaw.During oild chuck work, soft pawl, under the drive of master jaw, makes closed or opening movement, by Workpiece clamping or unclamp.Clamping different workpieces is ground, changes the clamping dimension of oild chuck by changing the position of soft pawl on master jaw.
When the larger axle class of manufacturing batch or disk-like accessory, for preventing destroying workpiece machined surface, ensure that workpiece is by the axiality requirement of clamping face and machined surface, must by the clamping face turning of soft for oild chuck pawl once.The conventional method of the soft pawl of turning inner clamping type as shown in Figure 1, inside the soft pawl of oild chuck, first clamp a circular base slab support soft pawl, and then turnery processing is carried out to the clamping face of soft pawl, make soft pawl clamping face diameter dimension equal by retaining part diameter dimension with workpiece.For the position making the central part of soft pawl size stroke become holding workpiece, the different soft pawl of turning clamping dimension by the gripper shoe of different-diameter size, therefore before the soft pawl of turning inner clamping type, will need the gripper shoe preparing multiple different size specification in advance.Equally, relative to the soft pawl of external clamping being added to the collar also needing man-hour to prepare different size.
In addition, because be clamped with gripper shoe inside soft pawl, the clamping face of soft pawl can not all by turnery processing, and processing dimension is once excessive, the gripper shoe that must more renew, and re-starts processing to soft pawl.During the soft pawl of turning, gripper shoe is clamped in inside soft pawl, and during oild chuck real work, workpiece is but clamped in the outside of soft pawl.Because soft pawl is different by the position supported, during actual holding workpiece, soft pawl clamping face will become horn mouth shape, thus affect the machining accuracy of workpiece and the chucking power of soft pawl.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of structure simple, easy to operate, and the soft pawl clamping device at inner clamping type and the processing of external clamping soft pawl of applying in a flexible way.
The technical solution adopted in the utility model is soft pawl clamping device, comprises clamp body, slide block type steady pin, screw and block; Described clamp body is thickness is 10 ~ 15mm, and external diameter is less than the circular disk of diameter of chuck size, and on described clamp body circular disk centered by the annular center of circle, circumferentially three to five deciles are provided with three to five vortex-like grooves; A slide block type steady pin is provided with in the vortex-like groove of described each clamp body; Described slide block type steady pin is fixed by screws on clamp body; Described slide block type steady pin is fixed on clamp body by block and screw.
Further, on described clamp body centered by the annular center of circle, circumferentially the quartering is provided with four vortex-like grooves.
The beneficial effects of the utility model are: the utility model delicate structure, simple to operate, easy to use, safe and reliable, and the scope of application is large, and with low cost, ensure that machining accuracy, reduces labour intensity, improve production efficiency.

Detailed description of the invention
Shown in accompanying drawings 2,3,4, soft pawl clamping device of the present utility model, comprises clamp body 1, slide block type steady pin 2 and screw 4.Described clamp body 1 for thickness be 10 ~ 15mm.External diameter is less than the circular disk of diameter of chuck size.On described clamp body 1 circular disk centered by the annular center of circle.Circumferentially trisection is provided with three vortex-like grooves 5.A slide block type steady pin 2 is provided with in the vortex-like groove 5 of described each clamp body 1.Described slide block type steady pin 2 is fixed on clamp body 1 by screw 4.
The utility model also comprises block 3, and described slide block type steady pin 2 is fixed on clamp body 1 by block 3 and screw 4.
On clamp body 1 described in the utility model centered by the annular center of circle, circumferentially the quartering is provided with four vortex-like grooves 5.Certainly circumferentially five vortex-like grooves 5 can also be set to by five deciles.
Three slide block type steady pins 2 of the present utility model are inserted in the screw counter bore of three soft pawls on oild chuck respectively.During oild chuck clamping, three slide block type steady pins 2 can adjust to optimum position automatically.Make three of chuck active forces suffered by soft pawl all equal.The slidably stroke of slide block type steady pin 2 in vortex-like groove 5 is very long, and therefore the utility model not only can fix the soft pawl of different clamping dimension.Save gripper shoe 9 and the collar of multiple different size specification.And it is whole to carry out stepless fine adjustment, makes soft pawl consumption drop to minimum.
Meanwhile, owing to not having the obstruction of gripper shoe 9, the clamping face of soft pawl can all by turnery processing, so during actual holding workpiece, the distortion of soft pawl clamping face is little, and clamp precision is high.
Embodiment one:
As shown in Figure 4, for the soft pawl 6 of turning inner clamping type, during use, first oild chuck should be flared to maximum, be adjusted the position of soft pawl on master jaw 10 according to workpiece by the diameter dimension of retaining part.Measure the distance of oild chuck center to soft pawl screw counter bore.Select the soft pawl clamping device conformed to its size.Then two slide block type steady pins 2 on soft pawl clamping device are inserted respectively the screw counter bore of two the soft pawls in oild chuck bottom.Left hand catches clamp body 1 left rotation and right rotation.Another slide block steady pin be left is made to aim at the screw counter bore of chuck top the 3rd soft pawl.Slide block type steady pin 2 is pressed in counterbore by the right hand.Both hands pressing clamp body 1, makes soft pawl clamping device and each soft pawl be close to.Opening and closing oild chuck repeatedly again.Both hands left rotation and right rotation clamp body 1.The position of adjustment slide block type steady pin 2 in vortex-like groove 5, makes soft pawl clamp the central authorities of position close to soft pawl stroke of this device as far as possible.After above-mentioned steps completes, i.e. clamping hydraulic chuck, starts to carry out turnery processing to the clamping face of soft pawl.
Embodiment two:
As shown in Figure 5, the collar that the utility model can also substitute different size specification fixes the soft pawl 12 of external clamping.Realize the turnery processing to the soft pawl 12 of external clamping.Its concrete using method is similar to the using method of the soft pawl of turning inner clamping type 6.
Above illustrated embodiment is better embodiment of the present utility model, only be used for conveniently the utility model being described, not any pro forma restriction is done to the utility model, have in any art and usually know the knowledgeable, if do not depart from the utility model carry in the scope of technical characteristic, utilize the utility model disclose the Equivalent embodiments changing or modify in the done local of technology contents, and do not depart from technical characteristic content of the present utility model, all still belong in the scope of the utility model technical characteristic.
