Abstract
The utility model relates to multifunctional hydraulic pulling force device, which comprises a hydraulic utensil, a wire compression joint plier frame, a three-jaw mechanism and a pulling force supporting frame. The hydraulic utensil is used as a power supply, and the wire compression joint plier frame, the three-jaw mechanism and the pulling force supporting frame are used as three tool heads. The wire compression joint plier frame is used for hydraulically pressing a press line and the pulling force supporting frame is used for pulling up a bearing with a small gap (the gap between the bearing and parts). The three-jaw mechanism is used for pulling up different models of bearings. The utility model has the advantages of novelty, peculiar, simple, and convenient structural design, large pulling up amounts, and steady and good pulling up effect.
Description
The utility model belongs to hydraulic tool and makes the field.
Prior art in the utility model prior art field is: existing chest expander (comprising the bearing driver-extractor) all adopts the screw thread transmission, its frictional resistance is big, the amount of pulling up is limited, use inconvenience, the bearing driver-extractor is rising when pulling out the bearing that varies in size, need with different claw hooks, so the semi-circular claw hook of required different model is too many.

Design of the present utility model is: 1, design philosophy: the power source of chest expander adopts that the hydraulic pressure utensil has that resistance is little, the amount of pulling up greatly, steadily, characteristics easily; The design of conductor compression jointing tong holder, three-jaw mechanism and three kinds of tool heads of pulling force support, having satisfied one is to make things convenient for line ball; Two is that the bearing that a pawl can adapt to different model pulls up; The 3rd, little gap (bearing and part gap) is convenient and reliable for pulling up.2, detailed organization plan: multifunction hydraulic chest expander, it comprises hydraulic pressure utensil 1, conductor compression jointing tong holder 4, three-jaw mechanism 12, the internal thread of conductor compression jointing tong holder 4 is connected with the cylinder body 13 of hydraulic press 1, the spiral shell button 3 that is connected of the internal thread of conductor compression jointing tong holder 4 and hydraulic pressure utensil 1 connects, and connects on the push rod 2 that spiral shell button 3 is enclosed within hydraulic pressure utensil 1 and is connected with the inwall of the cylinder body 13 of hydraulic pressure utensil 1; The spiral shell that is connected of the crowfoot underframe of three-jaw mechanism 12 and hydraulic pressure utensil 1 is buckled 3 end and is connected, and the thimble 6 of three-jaw mechanism 12 passes the axis hole on the crowfoot underframe and push rod 2 socket connections of hydraulic pressure utensil 1; The end that is connected screw socket 13 of the link 7 of pulling force support 14 and hydraulic pressure utensil 1 connects, and the thimble 6 of its pulling force support 14 passes the axis hole on the link 7 and push rod 2 socket connections of hydraulic pressure utensil 1.The both sides of the link 7 of pulling force support 14 are with pull bar 5 respectively, and an end of its pull bar 5 has a plug, and the other end of pull bar 5 is connected with bearing support 11, and the both sides of bearing support 11 divide seat that two involutory angle steel 9 are arranged, and bearing 10 and bearing bracket stand 8 are positioned at 9 in two involutory angle steel.Link 7 ovalizes.
The utility model compared with prior art, the one, changing the screw thread transmission is hydraulic drive, have stable drive, convenience, the amount of pulling up big, pull up the good characteristics of effect; The 2nd, the hydraulic pressure utensil matches with the tool heads of three kinds of different structures, realized line ball, different model bearing, pull up and the pulling up of little gap bearing (bearing and part gap); The 3rd, have structural design uniqueness, novelty, simple, convenient, practical advantage.
Description of drawings:
Fig. 1 is the structural representation of the hydraulic pressure utensil of multifunction hydraulic chest expander.
Fig. 2 is the structural representation that the lead line ball of multifunction hydraulic chest expander connects tong holder 4.
Fig. 3 is the main TV structure schematic diagram of the pulling force frame 14 of multifunction hydraulic chest expander.
