Abstract
The invention relates to an anti-shake internal expanding fixture which comprises a fixture body connected with the spindle of a numerical control machine tool, a movable connecting sleeve, a fixed core spindle and an expanding sleeve which are arranged inside the fixture body, and a pop rivet connected with the movable connecting sleeve and the expanding sleeve. The anti-shake internal expanding fixture is characterized in that a centrifugal pressing claw mechanism is sleeved on the fixture body; the centrifugal pressing claw mechanism consists of a support fixed on the fixture body, a bracket, a spring connected with the support and the bracket, a balance block arranged at one end of the bracket, and a pressing claw arranged at the other end of the bracket; and the pressing claw can be fastened to the side end of a workpiece. According to the centrifugal pressing claw mechanism, the pressing force of the pressing claw on the workpiece at different rotating speeds is changed by utilizing the centrifugal force generated by the balance block which is rotationally driven by the spindle of the machine tool, so that the shake of the workpiece is avoided, the product yield is improved, and the machining efficiency of the product is improved.
Description
Technical field
The present invention relates to a kind of jig, particularly relate to a kind of anti-shake internal expanding jig.
Background technology
For the processing of gearbox gear wheel-class parts on numerically controlled lathe, the internal expanding jig functional part that is absolutely necessary, if there is not internal expanding jig inner support workpiece, processing will be difficult to finish.
Existing internal expanding jig only has a kind of version: namely be comprised of jig body, axle, ringfeder and connecting rod etc., by tensioner gear class workpiece in the connecting rod pulling ringfeder.This technology adopts the mode of manual material loading, manual discharging, relies on merely operator's experience to determine whether part is first-class, after machining, manually takes off part by the operator again.This mode, itself just exists human factor to cause the many problems of workpiece percent defective, and turning is to carry out under fast state still more, because the workpiece jitter problem that high-speed turning brings has aggravated the raising of percent defective more, production efficiency is low.
Summary of the invention
Purpose of the present invention just is to overcome the defective of above-mentioned prior art, and the shake of a kind of effective reduction workpiece when high-speed turning is provided, and improves the anti-shake internal expanding jig of product percent of pass and production efficiency.
The technical scheme of taking for achieving the above object is:
A kind of anti-shake internal expanding jig, comprise the jig body that is connected with main shaft of numerical control machine tool and be installed in removable adapter sleeve, fixed central spindle, the ringfeder of its inside and connect the blind rivet of removable adapter sleeve and ringfeder, it is characterized in that: be set with centrifugal pressing claw mechanism on the described jig body, described centrifugal pressing claw mechanism is comprised of the spring that is fixed on bearing, support, connection bearing and support on the jig body, the paw that is installed in the balance weight of support one end and is installed in the support other end, and described paw can be buckled in the workpiece side.
Airtight detection and location dish is installed on the described jig body, and centrifugal pressing claw mechanism is fixedly mounted on the airtight detection and location dish.
Described centrifugal pressing claw mechanism is 3 covers, evenly distributes.
The present invention is by arranging centrifugal pressing claw mechanism, paw is to the thrust of workpiece when utilizing machine tool chief axis to rotarily drive centrifugal force that balance weight produces to change different rotating speeds, thereby avoid the workpiece shake, improved the qualification rate of product, improved the working (machining) efficiency of product.
Description of drawings
Fig. 1 is the structural representation sketch of the anti-shake internal expanding jig of the present invention.
The specific embodiment
Anti-shake internal expanding jig of the present invention is described below in conjunction with accompanying drawing.
As shown in Figure 1, anti-shake internal expanding jig of the present invention comprises the jig body 2 that is connected on the Digit Control Machine Tool spindle nose 1, but the adapter sleeve 3 of move left and right is installed in jig body 2, is fixed with mandrel 5 in the jig body 2 of adapter sleeve 3 one ends.Mandrel 5 outer race are equipped with ringfeder 6, and the blind rivet in the through hole 7 is connected with adapter sleeve 3 ringfeder 6 on the mandrel 5 by being through.Workpiece 14 is enclosed within on the ringfeder 6, thereby by adapter sleeve 3 pulling ringfeders 6 tensioner workpiece 14.
Improvements of the present invention are: be set with airtight detection and location dish 4 in jig body 2, on this airtight detection and location dish 4 centrifugal pressing claw mechanism be installed.This centrifugal pressing claw mechanism be by be fixed on bearing 8 on the airtight detection and location dish 4 by bearing pin 13, be installed in spring 9 on the bearing 8, by the hard-wired balance weight 11 of support 10, support 10 1 ends and the hard-wired paw 12 of the support other end that spring 9 is connected with bearing 8, described paw can be buckled in workpiece 14 sides.Centrifugal pressing claw mechanism evenly distributes, and usually is set to 3 covers.
After workpiece 14 was in place, adapter sleeve 3 pulling blind rivets 7 drove ringfeder 6 tensioner parts; Machine tool chief axis 1 rotation this moment, centrifugal pressing claw mechanism (comprising balance weight, support, bearing, spring, paw etc.) is by adjusting the weight of balance weight, (rotating speed is higher to the thrust compressing component of part for paw when utilizing the centrifugal force of balance weight to change different rotating speeds, the outside centrifugal force of balance weight is larger, and the power that passes to paw 12 by support 10 is just larger, otherwise, paw is less to the thrust of part), after part machines, the main shaft stall, spring flicks paw.Above process is finished airtight detection, tensioner to processing parts, is compressed, unclamps.
