Description

Tungsten ring car outer tooling

Technical Field

The utility model relates to a tungsten ring car outer frock.

Background

When the tungsten ring is machined, a numerical control milling machine is needed to perform grooving treatment on the outer wall of the tungsten ring.

The currently known processing methods are:

and clamping the workpiece by using a lathe to machine the inner diameter, and machining the workpiece in a single piece. However, the ring is required to have a thick enough wall thickness and a rigidity enough to clamp the workpiece without deformation, otherwise the ring is deformed by the clamping force, and the workpiece cannot be machined or the required dimensional accuracy and shape accuracy cannot be achieved.

And clamping and processing a plurality of pieces by using an outer mould with a fixed outer diameter. The main disadvantage of this processing method is that the outer diameter of the workpiece and the inner diameter of the clamping fixture are separated by a certain gap, usually the gap is above 0.08mm, and the shape and position accuracy of all rings processed by this method cannot be guaranteed; and the machined workpiece has uneven thickness. For example, chinese utility model patent document, publication No. CN217860078U discloses a processing clamp for milling and cutting a tungsten ring. Moreover, such a fixture is not suitable for machining annular workpieces with different diameters.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

Referring to fig. 1-3, a tungsten ring car outer cover tool comprises a chuck 10 and a plurality of jaws 110 arranged on the chuck 10, wherein a car outer cover module 210 is fixedly arranged on each jaw 110, the plurality of car outer cover modules 210 surround to form a ring-shaped car outer cover 20, a ring-shaped workpiece 30 is sleeved on the outer wall of the ring-shaped car outer cover 20, and the car outer cover module 210 is attached to or separated from the inner wall of the ring-shaped workpiece 30 under the driving of the jaws 110.

The utility model discloses in, chuck and jack catch adopt current product.

The utility model discloses under the chuck drives a plurality of jack catchs synchronous motion, it can drive motor car cover tire module outwards or inwards move. When the annular workpiece needs to be fixed, the whole set of annular workpiece is sleeved on the annular type outer tire, then the clamping jaws are driven by the chucks to move outwards, the outer tire module is attached to the inner wall of the annular workpiece, and then the annular workpiece is tightly pushed to realize supporting and fixing. When the workpiece needs to be taken out, the clamping jaw is driven by the chuck to separate the vehicle outer cover module from the annular workpiece. Compared with the prior art in which the outer clamping fixture is adopted for fixing, the outer clamping fixture is clamped and fixed from the side wall of the annular workpiece, so that the problem of position eccentricity caused by intermittence in the existing outer clamping fixture fixing process is solved. So as to realize more accurate processing. And compare with current lathe clamping work piece, the utility model discloses can a plurality of work pieces of simultaneous processing, the accuracy of centre gripping work piece is more accurate, avoids the ring to receive the clamping power to cause the problem of deformation.

Referring to fig. 1, a positioning boss 211 for positioning and attaching to the annular workpiece 30 is disposed on an outer wall of a lower portion of the tire and tire module 210. The positioning boss 211 can limit the ring-shaped workpiece 30 from moving downward, so as to support the workpiece. That is, when the ring-shaped workpiece 30 needs to be assembled, the ring-shaped workpiece 30 is firstly sleeved on the ring-shaped outer tire 20 from top to bottom, the lowermost ring-shaped workpiece 30 is attached to the positioning boss 211 to realize the limit, then the plurality of jaws are driven by the chuck to synchronously move outwards, in the process, the jaws drive the outer tire module 210 to gradually approach the inner wall of the ring-shaped workpiece 30, and finally a certain force is applied to support the inner wall of the ring-shaped workpiece 30 to realize the fixing effect.

Referring to fig. 1, a ring-shaped cover 40 for pressing the uppermost ring-shaped workpiece 30 is detachably attached to the upper end surface of the ring-shaped outer tire 20. The ring-shaped pressing cover 40 further limits the upper and lower positions of the entire set of ring-shaped workpieces 30 to prevent the risk of the ring-shaped workpieces 30 being separated from the upper side.

The utility model discloses in, be equipped with first screw hole on the up end of every car cover tire module 210 be equipped with first mounting hole on the position that ring type gland 40 corresponds first screw hole, penetrate locking bolt and first screw hole threaded connection at first mounting hole.

In the present invention, the claw 110 has three. The number of the clamping jaws can be adjusted according to different fixing requirements, and can be increased to four or five.

Referring to fig. 1, the vehicle outer tire module 210 is provided with a right-angle connector 212 fixedly connected with the claw 110.

The utility model discloses in, car cover tire module 210 adopts the welding or adopts the fastener to fix on the jack catch 110. Welding is the most direct connection method, and the defect of the welding is that the welding is not convenient to disassemble and replace. And the fastener is adopted, and a bolt or other existing detachably connected fixing parts are selected for fixing. Is convenient for later-period disassembly and replacement.
