Description

Technical Field

[0001] This utility model relates to the field of automatic turntable technology, and in particular to a heavy-duty automatic turntable for use in extremely harsh environments. Background Technology

[0002] A heavy-duty automatic rotary table is a platform that can rotate automatically and is specifically designed to carry very heavy workpieces. In automated machining or processing, the heavy-duty automatic rotary table positions and rotates heavy workpieces to the required angle so that machines (such as robots, spray guns, and machine tool spindles) can process the workpieces from all directions without the need for frequent manual adjustments to the workpiece position, greatly improving efficiency and consistency.

[0003] In the operation of existing heavy-duty automatic turntables, some working environments may contain a large amount of dust. When there is too much dust, it can enter the interior through the gaps of the automatic turntable, causing the bearings to jam. To address this problem, we propose a heavy-duty automatic turntable for use in extremely harsh environments. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heavy-duty automatic turntable for use in extremely harsh environments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A heavy-duty automatic rotary table for use in extremely harsh environments includes a flange turntable, which is mounted on the upper end of a connecting spindle. An outer dust cover is fitted onto the lower end face of the flange turntable, and a dustproof curtain is installed below the outer side of the outer dust cover. A spindle seat is fitted between the connecting spindle and the inner surface of the outer dust cover. An upper bearing is installed on the upper part of the inner wall of the spindle seat, and a lower bearing is installed on the lower part of the inner wall of the spindle seat. A lower bearing sealing end cover is installed at the lower end of the connecting spindle via a spindle locking ring. Two dustproof sealing strips are placed between the lower end of the outer dust cover and the lower end of the spindle seat. A spindle seat dust cover is fitted onto the surface of the spindle seat, and a spindle seat sealing ring is provided on the surface of the spindle seat.

[0006] Preferably, a sleeve is fixed to the lower end of the flange turntable, the upper end of the connecting spindle is inserted into the sleeve, and the flange turntable and the connecting spindle are fixedly connected by bolts.

[0007] Preferably, a turntable sealing gasket is laid between the lower end of the sleeve rod and the upper part of the outer dust cover, and a turntable sealing gasket is laid between the top of the main shaft seat dust cover and the inner wall of the outer dust cover.

[0008] Preferably, the lower end of the spindle seat is fixed with a disc by multiple bolts, and the disc has a through hole in the middle that matches the sealing end cover of the lower bearing.

[0009] Preferably, the surface of the spindle seat is provided with an annular groove, and the depth of the inner wall of the annular groove is the same as half the surface thickness of the spindle seat sealing ring.

[0010] Preferably, a rubber ring is fitted on the upper outer side of the dustproof curtain, and the rubber ring and the dustproof curtain are threadedly connected to the outer dustproof cover by multiple bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: All transmission parts in this device that come into contact with sand and dust adopt a multi-layer labyrinth-style sealing and isolation structure. A dustproof curtain is installed on the lower side of the outer dust cover, which can ensure the isolation of most sand and dust. A very small amount of dust is further suppressed at the second dustproof sealing strip. When a small amount of dust enters the dust cover of the spindle seat, it can be completely sealed off from the spindle seat by the protection of the spindle seat seal ring. This can prevent the upper and lower bearings in the spindle seat from jamming. This high-load, high-speed turntable has a reliable and stable structure, and can ensure the rapid switching of multi-speed or forward and reverse rotation of the turntable. It has wide compatibility and strong applicability. Attached Figure Description
