Abstract
The utility model relates to an anti-shake swelling inside fixture. The anti-shake swelling inside fixture comprises a fixture body connected with a main shaft of a numerical control machine tool, a movable connecting sleeve, a fixed core shaft, a swelling sleeve and a pulling rivet. The movable connecting sleeve, the fixed core shaft and the swelling sleeve are installed in the inner portion of the fixture body. The pulling rivet is connected with the movable connecting sleeve and the swelling sleeve. The anti-shake swelling inside fixture is characterized in that a centrifugal pressing claw mechanism is installed on the fixture body in a sleeved mode. The centrifugal pressing claw mechanism is composed of a supporting seat, a supporting frame, a spring, a balancing block and a pressing claw. The supporting seat and the supporting frame are fixed on the fixture body. The spring is connected with the supporting seat and the supporting frame. The balancing block is installed at one end of the supporting frame. The pressing claw is installed at the other end of the supporting frame. The pressing claw can be buckled at a side end of a workpiece. According to the anti-shake swelling inside fixture, the centrifugal pressing claw mechanism is set, centrifugal force produced when revolving of the main shaft of the machine tool drives the balancing block is used to change pressing force on a workpiece when the pressing claw revolves at different speeds, thus workpiece shaking is avoided, percent of pass of a product is improved and machining efficiency of the product is improved.
Description
Technical field
The utility model relates to a kind of jig, particularly relates 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
The purpose of this utility model 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 utility model 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 utility model.
The specific embodiment
Anti-shake internal expanding jig of the present utility model is described below in conjunction with accompanying drawing.
As shown in Figure 1, anti-shake internal expanding jig of the present utility model 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 utility model 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.
