Abstract
A pull plate consists of a tray and a slide block. A through hole connected with one end of the pull rod is formed in the center of the tray; a plurality of sliding chutes horizontally extending to the center of the tray are arranged in the middle of the side surface of the tray at intervals along the circumference; a plurality of guide grooves correspondingly communicated with the sliding grooves are formed below the tray; the tray is provided with a plurality of positioning holes which are correspondingly communicated with the sliding grooves and correspond to the guide grooves. The slider is arranged in the tray sliding groove, one end of the slider is provided with a positioning pin, one end of the positioning pin can be inserted into the positioning hole on the tray, and the other end of the positioning pin extends out of the guide groove below the tray. The pull plate has firm structure and is not easy to damage; the diameter is adjustable, the bearing is integrally pulled, and the connection is reliable; not easy to damage the bearing, etc.
Description
Technical Field
The utility model relates to a draw the dish, especially a draw dish with adjustable diameter size.
Background
The existing bearing assembling and disassembling tools are all connected with a bearing by adopting a pulling claw for pulling. The connection between the pulling claw and the bearing is unreliable, and the sliding is easy to slip; the pulling claw is easy to break; the pull claw has inconsistent tension and is easy to damage the bearing and the like.
SUMMERY OF THE UTILITY MODEL
The utility model provides a pull disc for assembling and disassembling a bearing, which is composed of a tray and a slide block, aiming at the defects and shortcomings of the prior art, the center of the tray is provided with a through hole connected with one end of a pull rod; a plurality of sliding chutes horizontally extending to the center of the tray are arranged in the middle of the side surface of the tray at intervals along the circumference; a plurality of guide grooves correspondingly communicated with the sliding grooves are formed below the tray; the tray is provided with a plurality of positioning holes which are correspondingly communicated with the sliding grooves and correspond to the guide grooves, the sliding block is arranged in the sliding groove of the tray, one end of the sliding block is provided with a positioning pin, one end of the positioning pin can be inserted into the positioning hole on the tray, and the other end of the positioning pin extends out of the guide groove on the lower surface of the tray.
The utility model has the advantages that: the sliding block in the tray is stirred through the bolt, and the diameter of the pull disc can be adjusted. Firstly, the pull disc can be matched with bearings with different diameters, so that the bearings can be integrally pulled, the contact area is large, the stress is balanced, and the bearings are not easy to damage; the pull disc is in plane contact with the bearing, so that the connection is reliable, the sliding is difficult, and the pull disc is particularly suitable for assembling and disassembling large and super-large bearings; thirdly, the pull plate is firm and not easy to damage.
Drawings
Fig. 1 is a longitudinal sectional view of the present invention.
Fig. 2 is a view in the direction P of fig. 1.
In the figure, 1, a tray, 2, a slide block, 3, a pull rod, 10, a through hole, 11, a sliding groove, 12, a guide groove, 13, a positioning hole and 20, a positioning pin are arranged.
Detailed Description
As shown in fig. 1 and fig. 2, the technical solution adopted by the present embodiment is: a pull disc comprises a tray 1 and a slide block 2, wherein the center of the tray 1 is provided with a through hole 10 connected with one end of a pull rod 3; a plurality of sliding chutes 11 which horizontally extend to the center of the tray 1 are arranged in the middle of the side surface of the tray 1 at intervals along the circumference; a plurality of guide grooves 12 communicated with the sliding grooves 11 are formed below the tray 1; the tray 1 is provided with a plurality of positioning holes 13 which are correspondingly communicated with the sliding grooves 11 and correspond to the guide grooves 12, the sliding block 2 is arranged in the sliding grooves 11 of the tray 1, one end of the sliding block 2 is provided with a positioning pin 20, one end of the positioning pin 20 can be inserted into the positioning holes 13 on the tray 1, and the other end of the positioning pin 20 extends out of the guide grooves 12 below the tray 1.
When assembling or disassembling the bearing, according to the diameter of the bearing, the positioning pin 20 is screwed to withdraw from the positioning hole 13, then the positioning pin 20 is shifted, the length of the slide block 2 extending out of the tray 1 is adjusted until the diameter of the slide block is approximately matched with the diameter of the bearing, then the positioning pin 20 is screwed to enable one end of the positioning pin 20 to be inserted into the positioning hole 13 on the tray 1, and after the slide block 2 is positioned, the bearing is integrally pulled into the bearing hole or pulled out from the bearing hole through the pull rod 3.
Claims (2)
1. A pull plate is characterized in that: the pull disc consists of a tray and a sliding block, and a through hole connected with one end of the pull rod is formed in the center of the tray; a plurality of sliding chutes horizontally extending to the center of the tray are arranged in the middle of the side surface of the tray at intervals along the circumference; a plurality of guide grooves correspondingly communicated with the sliding grooves are formed below the tray; the tray is provided with a plurality of positioning holes which are correspondingly communicated with the sliding grooves and correspond to the guide grooves, the sliding block is arranged in the sliding groove of the tray, and one end of the sliding block is provided with a positioning pin.
2. A pull cup according to claim 1, wherein: one end of the positioning pin can be inserted into the positioning hole on the tray, and the other end of the positioning pin extends out of the guide groove on the lower surface of the tray.
