And easily cause the damage of band edge bearing.According to statistics, using traditional sealing method often 10 or so bearings of processing will be by
Damage, seal operation will be forced to interrupt, and seriously affect production efficiency.
Capacitor generally comprises outer cushion rubber sealing 7, outer cushion rubber 2, cover board 6, interior cushion rubber 1, inner ring sealing 5 and positive terminal
3 and negative terminal 4.
Embodiment:
Referring to shown in attached drawing 1-4, ring seal device in large capacity hollow bolt type aluminum capacitor cover board, including interior sealing seat
8, sealing needle construction 9 and interior sealing shaft 10, the interior sealing shaft 10 are mounted on closing device in double end, the interior sealing seat
8 are mounted on the top of interior sealing shaft 10, and interior sealing shaft 10 is clamped in the shaft of closing device host, in capping processes in drive
Sealing shaft uniform rotation, the interior sealing needle construction 9 of the double end is fixed on interior sealing seat 8, under the drive of the closing device,
Sealing needle construction 9 in the double end is driven to rotate and then be sealed to capacitor cover plate inner ring.
Specifically, the interior sealing seat 8 is made of upper junction plate 81 and lower cover plate 82, the upper junction plate 81 is fixed on institute
Interior 10 top of sealing shaft is stated, sealing needle construction is mounted between the upper junction plate 81 and the lower cover plate 82 in the double end,
Sealing needle construction includes main part and two sealing needle portions in the double end, and two sealing needle portions are fixed with the main part
It is integrated, and is provided with central channel 13 among the main part, the lower cover plate 82 is arranged centre bore 12, in the centre bore 12
Be arranged screw, the screw pass through centre bore 12 and will in the double end seal needle construction limit in central channel 13, it is described in
Heart groove width 4.2mm, deep 1mm, the screw is screw M4；The diameter of screw M4 is 4mm, and the width of central channel is 4.2mm, also
To say that the automatic alignment position-limiting action in rotary course may be implemented in sealing needle construction in double end, it is axial can be automatic micro-
It adjusts；
The interior sealing seat 8 is equipped with screw hole, passes through screw hole for lower cover plate 82 and upper connection by lock screw 11
Plate 81 is fixedly connected.
Sealing needle construction 9 is connected on interior sealing seat 8 in double end, is actually above hollow capacitor clamping fixture seat
A piece axis.
Two sealing needle portions are symmetrically arranged at the main part two sides, and the sealing needle portion is machined with a circle indent circle
91, the section of the indent circle is semicircle；The setting of indent circle 91 be in order to more preferably with the aluminum hull in inner ring is seamless contacts, together
When by attached drawing 2 as it can be seen that indent circle 91 and main part junction are also machined with circular arc chamfering face, 92, the processing in circular arc chamfering face 92
So that sealing needle construction preferably compresses limit with inner ring during envelope in rotation in double end, interior seal structure it is high-quality.
The novel hollow capacitor cover plate inner ring closing device of the utility model will seal needle construction using double end.It is this new
Mainly by interior sealing seat 8, the interior sealing needle construction 9 of double end forms the double end sealing needle device of design.It is grasped in the sealing of cover board inner ring
