For solving the problems of the technologies described above, the utility model scissors bearing pin plug-in and pull-out device comprises the head contiguous block, the afterbody contiguous block, fixedly connected, mobile contiguous block, screw mandrel, pull bar and four poles, described head contiguous block is located at by first bolt respectively in described four pole two ends, the afterbody contiguous block, fixedly connected with mobile contiguous block two ends and become flexible connection, described head contiguous block and afterbody contiguous block are positioned at position in opposite directions, described fixedly connected with mobile contiguous block be positioned at position in opposite directions, described mobile contiguous block center is provided with a hole, described screw mandrel one end is a turret head, described screw mandrel is twisted in the silk hole of described mobile contiguous block and the other end is located at described fixedly connected center, described screw mandrel piece axially is fixedly connected with fixedlying connected, radially be to flexibly connect, described afterbody contiguous block side is provided with projection, described projection center has through hole, described pull bar one end is movably connected on described head contiguous block side by second bolt, and its other end is provided with external screw thread and penetrates in the projection through hole of described afterbody contiguous block.
The projection through hole of above-mentioned pull bar and afterbody contiguous block is a matched in clearance.
Because the utility model scissors bearing pin plug-in and pull-out device has adopted technique scheme, promptly adopt four poles to connect head contiguous block, afterbody contiguous block, fixedly connected respectively and mobile contiguous block two ends constitute a rhombus, mobile contiguous block center has a hole, screw mandrel is screwed in the hole and an end is fixed in fixedly connected center, afterbody contiguous block side is provided with the projection that has through hole, pull bar one end is provided with external screw thread and penetrates the through hole of projection, and the pull bar other end is movably connected on head contiguous block side by second bolt; Utilize and originally draw the pin device can conveniently carry out the plug of all kinds of bearing pins, the bearing pin plug is time saving and energy saving, plug efficient height, and avoided bearing pin plug process safe hidden danger.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the utility model scissors bearing pin plug-in and pull-out device.
The specific embodiment
As shown in Figure 1, the utility model scissors bearing pin plug-in and pull-out device comprises head contiguous block 1, afterbody contiguous block 2, fixedly connected 3, mobile contiguous block 4, screw mandrel 6, pull bar 5 and four poles 7, described head contiguous block 1 is located at by first bolt 8 respectively in described four pole 7 two ends, afterbody contiguous block 2, fixedly connected 3 with mobile contiguous block 4 two ends and become flexible connection, described head contiguous block 1 is positioned at position in opposite directions with afterbody contiguous block 2, described fixedly connected 3 with mobile contiguous block 4 be positioned at position in opposite directions, described mobile contiguous block 4 centers are provided with a hole, described screw mandrel 6 one ends are turret heads 61, described screw mandrel 6 is twisted in the silk hole of described mobile contiguous block 4 and the other end is located at described fixedly connected 3 center, described screw mandrel 6 pieces 3 axially is fixedly connected with fixedlying connected, radially be to flexibly connect, described afterbody contiguous block 2 sides are provided with projection 21, described projection 21 centers have through hole, described pull bar 5 one ends are movably connected on described head contiguous block 1 side by second bolt 9, and its other end is provided with external screw thread 51 and penetrates in the projection through hole of described afterbody contiguous block 2.
Above-mentioned pull bar 5 is matched in clearance with the projection through hole of afterbody contiguous block 2.
The utility model scissors bearing pin plug-in and pull-out device adopts four poles to connect head contiguous block, afterbody contiguous block, fixedly connected respectively and mobile contiguous block two ends constitute a rhombus, mobile contiguous block center has a hole, screw mandrel is screwed in the hole and an end is fixed in fixedly connected center, afterbody contiguous block side is provided with the projection that has through hole, pull bar one end is provided with external screw thread and penetrates the through hole of projection, and the pull bar other end is movably connected on head contiguous block side by second bolt; Ben La pin device is when the drawing bearing pin, at first pull bar one end is pulled out in the projection through hole of afterbody contiguous block and be axle center Rotate 180 degree with second bolt of head contiguous block, the end of thread of pull bar is screwed in the screw on bearing pin top, do not have screw as the bearing pin top and then can on-the-spotly process a screw that mates, fixedly the afterbody contiguous block is on frame or mounting article, use Wrench to be placed on the turret head of screw mandrel then and turn screw mandrel, this moment, mobile contiguous block outwards moved along screw mandrel, drove head contiguous block and the outwards mobile bearing pin of extracting of pull bar by four poles; And when inserting bearing pin, originally draw the pull bar of pin device to recover former state, and the end of thread of pull bar is screwed into the screw on bearing pin top, and fixedly the afterbody contiguous block is on the frame of bearing pin, and rotary screw rod makes the head contiguous block drive pull bar and inwardly pushes, and puts in place so that bearing pin is inserted; Utilize and originally draw the pin device can conveniently carry out the plug of all kinds of bearing pins, the bearing pin plug is time saving and energy saving, plug efficient height, and avoided bearing pin plug process safe hidden danger.
