A kind of casing processing tool described in the utility model, it is characterised in that：Include for fix the pedestal of casing, with
The casing cavity shape it is identical and with the elastic obturator of its inner surface cooperation, the lid being located above the elastic obturator
The taper shank for the adjustable use level that plate, lower part are connect across the cover board and elastic obturator with the base engagement.
Further, the lower part of the taper shank is equipped with external screw thread；The middle part of the cover board and elastic obturator be equipped with it is described
The compatible through-hole of the middle part conical surface of taper shank；The middle part of the pedestal is equipped with threaded hole, the lower part of taper shank pass through the cover board and
Through-hole and the threaded hole of the middle of the base in the middle part of elastic obturator are connected.
Further, the upper surface of the pedestal is equipped with positioning spigot, the lower end inner cavity of the positioning spigot and the casing
It is adapted.
Further, pressing plate is connected with by screw rod on the pedestal, which is used to compress the installation side of the casing.
Further, the elastic obturator is polyurethane material.
Further, the pedestal is equipped with weight loss groove.
The beneficial technique effect of the utility model：
It is placed on pedestal due to devising pedestal, elastic obturator, cover board and taper shank, casing, elastic obturator and casing
Inner cavity cooperation, cover board is located at the upper surface of elastic obturator, and taper shank passes through cover board and elasticity obturator to be connect with base engagement, mistake
The use level for adjusting taper shank and pedestal, can be adjusted the deflection of elastic obturator, so that elastic obturator pair
Casing carries out support appropriate, improves the rigidity of casing, reduces the deflection of casing in process；It alleviates simultaneously
Occur in process allow knife, shake knife phenomena such as, ensure that the processing quality of casing, improve machining accuracy and efficiency.By
In the Design Orientation seam allowance on pedestal, installation of the casing on pedestal is facilitated；Due to being connected with pressure by screw rod on pedestal
Plate so that casing is fastened on pedestal, it is therefore prevented that casing is loosened and rotated in process.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1- casings, 2- pedestals, 3- elasticity obturators, 4- cover boards, 5- taper shanks, 6- pressing plates, 7- screw rods；
11- installs side；
21- positioning spigots, 22- weight loss grooves.
Specific implementation mode
It elaborates to the utility model below in conjunction with drawings and examples.The wherein orientation such as described "upper", the "lower"
Word is only limitted to the orientation in attached drawing.
A kind of casing processing tool shown in Figure 1, it is characterised in that：Include for fix the pedestal 2 of casing 1, with
1 cavity shape of the casing it is identical and with the elastic obturator 3 of its inner surface cooperation, be located above the elastic obturator 3
Cover board 4, lower part pass through the taper shank 5 of the cover board 4 and elastic obturator 3 and the adjustable use level of the mating connection of the pedestal 2.Bullet
Property obturator 3 be global formation, shape is identical as 1 cavity shape of casing.By adjusting the use level of taper shank 5 and pedestal 2, energy
Enough deflections for adjusting elastic obturator 3, so that elastic obturator 3 carries out support appropriate to casing 1, to improve casing
Rigidity, reduce casing deflection in process；Can mitigate simultaneously occur in process make knife, the knife that shakes etc. existing
As ensureing the processing quality of casing, improving machining accuracy and efficiency.
The lower part of the taper shank 5 is equipped with external screw thread；The middle part of the cover board 4 and elastic obturator 3 is equipped with and the taper shank 5
The compatible through-hole of the middle part conical surface；The middle part of the pedestal 2 is equipped with threaded hole, and the lower part of taper shank 5 passes through the cover board 4 and bullet
Property the middle part of obturator 3 through-hole and the threaded hole at 2 middle part of the pedestal be connected.
The upper surface of the pedestal 2 is equipped with positioning spigot 21, the lower end inner cavity phase of the positioning spigot 21 and the casing 1
Adaptation；Positioning spigot 21 facilitates casing 1 to be positioned when coordinating with pedestal 2.Weight loss groove 22 is additionally provided on pedestal 2；For mitigating bottom
The weight of seat 2, it is cost-effective.
Pressing plate 6 is connected with by screw rod 7 on the pedestal 2, which is used to compress the installation side 11 of the casing 1.It is logical
The installation side 11 that pressing plate 6 presses casing 1 is crossed, casing 1 rotation and bounce upwards in processing can be prevented.
The elasticity obturator 3 is polyurethane material.Polyurethane has higher resilience, excellent shock-absorbing performance, fits
Answering property is extensive, and moderate, is highly suitable as packing material.Elastic obturator can also be the elastic materials such as rubber.
Since the upper inner diameter of casing 1 is less than its underpart internal diameter, when assembly, first by the elastic obturator 3 of global formation from
The lower section of casing 1 is fitted into the inner cavity of casing 1 so that elastic obturator 3 is bonded with the inner surface of casing 1；By on pedestal 2
Positioning spigot 21 positions casing 1, then by adjusting screw rod 7 so that pressing plate 6 is pressed on the installation side 11 of casing 1；From
The top of casing 1 is put into cover board 4, and taper shank 5 is finally passed through the through-hole of cover board 4 and elastic obturator 3 and the threaded hole on pedestal 2
It is connected.The deflection of elastic obturator 3 is adjusted by adjusting screw-in amount of the taper shank 5 in pedestal 2, so that elastic
Obturator 3 plays good supporting role to casing 1, can increase the rigidity of casing, reduces the change of casing in process
Shape amount；Can mitigate simultaneously occur in process allow knife, shake knife phenomena such as, ensure the processing quality of casing, improve processing
Precision and efficiency.
