Description
Technical Field
The utility model belongs to the technical field of machine part handling instrument and specifically relates to a quick self-holding draws horse, but quick clamping bearing class spare part, greatly reduced operator intensity of labour.
Background
At present, the most of the screw extractor in the market is a claw hook type screw extractor, which generally comprises a screw rod, a nut and a pulling claw hung (or hinged) on the nut. When the bearing pulling device is used, the pulling claw is buckled on the outer edge of the bearing, the screw rod is propped against the end face of the shaft, and the screw rod is rotated to pull the bearing. The existing puller generally cannot automatically clamp bearing mechanical parts needing to be assembled and disassembled, is very complicated in practical production and use, and when an operator assembles and disassembles the bearing mechanical parts, all the pull legs of the puller are basically held against the bearing parts by one hand, and the screw rod is rotated by the other hand, so that the operation is troublesome, time and labor are wasted, the labor intensity is high, and the working efficiency is low.
Disclosure of Invention
The utility model aims at overcoming the defects of the prior art and providing a quick automatic clamping puller which has reasonable design, simple structure, easy manufacture and convenient use.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a quick self-holding draws horse, by the body frame, draw the leg, even board, lead screw, top cover, steel wire retaining ring, steel ball, hexagon head bolt, full metal hexagonal lock nut, rocker, torsional spring etc. and constitute its characterized in that: the body frame both ends are respectively through hexagon head bolt, two leg draws about all-metal hexagonal lock nut and even board are connected, the torsional spring is ridden on the body frame through hexagon head bolt fastening on even board, another leg of torsional spring is hung on the side of even board, the body frame is equipped with the internal thread through-hole, the lead screw passes through body frame internal thread through-hole, be equipped with one end in the centre bore of lead screw upper end and take bellied rocker, the bottom of lead screw is connected with the top cover through the steel wire retaining ring, install the steel ball between lead screw and top cover.
The torsional spring of the puller rides on the main frame and is fixed on the connecting plate through the hexagon head bolt, and the other leg of the torsional spring is hung on the side surface of the connecting plate. When the two pull legs are respectively broken off by two hands, the torsion spring is subjected to torsion bending and stores energy; after the puller is sleeved on the bearing workpiece, only two hands are needed to be loosened, and at the moment, the torsion spring quickly releases energy, so that the connecting plate and the pull leg are driven to be quickly closed towards the middle, and the purpose of quickly clamping the workpiece is achieved.
The utility model relates to a rationally, simple structure, easy manufacturing, use, convenient operation, labour saving and time saving can press from both sides tight bearing class spare part fast, greatly reduced operator intensity of labour.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a top view of fig. 1.
The labels in the figure are: 1. the main frame, 2, draw the leg, 3, even board, 4, lead screw, 5, top cover, 6, steel wire retaining ring, 7, steel ball, 8, hexagon head bolt, 9, all-metal hexagonal lock nut, 10, rocker, 11, torsional spring.
Detailed Description
As shown in fig. 1 and 2: the utility model provides a quick self-holding draws horse, includes body frame 1, draws leg 2, even board 3, lead screw 4, top cover 5, steel wire retaining ring 6, steel ball 7, hexagon head bolt 8, all-metal hexagonal lock nut 9, rocker 10, torsional spring 11, its characterized in that: 1 both ends of body frame are respectively through hexagon head bolt 8, two leg extensions 2 about all-metal hexagonal lock nut 9 and even board 3 are connected, torsional spring 11 rides on body frame 1 and fixes on even board 3 through hexagon head bolt 8, another leg of torsional spring 11 is hung on even side of board 3, body frame 1 is equipped with the internal thread through-hole, lead screw 4 passes through 1 internal thread through-hole of body frame, be equipped with one end in the centre bore of lead screw 4 upper end and take bellied rocker 10, lead screw 4's bottom is connected with top cover 5 through steel wire retainer ring 6, install steel ball 7 between lead screw 4 and top cover 5.
When the device is used, two pull legs 2 are respectively broken off by two hands, the pull legs 2 drive the connecting plate 3 to rotate towards the left side and the right side around the hexagon head bolt 8, and at the moment, the torsion spring 11 is subjected to torsion bending and stores energy; after the puller is sleeved on a bearing workpiece, only two hands are needed to be loosened, and at the moment, the torsion spring 11 releases energy rapidly, so that the connecting plate 3 and the pull leg 2 are driven to be closed rapidly towards the middle screw rod 4, the purpose of rapidly clamping the workpiece is achieved, and meanwhile, the symmetry degree of the clamped workpiece can be ensured.
To sum up, the utility model relates to a rationally, simple structure, easy manufacturing, use, convenient operation, labour saving and time saving can the tight bearing class spare part of quick clamp, greatly reduced operator intensity of labour.
