Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
As Fig. 1, shown in Fig. 2, this large-scale driver-extractor, comprise base 9, with the fixation clip 2 be vertically set on above base 9 and gripper shoe 4, level connection joint a pair pull bar 10 in fixation clip 2 and gripper shoe 4, pull bar 10 near gripper shoe 4 end is provided with screw thread 11, the sleeve pipe 12 having adjusting nut 7 to connect is overlapped on the screw thread 11 of gripper shoe 4 end, sleeve pipe 12 end connects one through the movable pressing board 3 on a pair pull bar 10, movable pressing board 3 and gripper shoe 4 are respectively equipped with for placing the U-type groove dismantling major axis, fixation clip 2 is provided with one for ejecting the push rod 15 of dismounting major axis, push rod 15 is provided with push rod handle 8, the side of base 9 is provided with suspension bracket 1, by adjusting nut 7 moving horizontally along pull bar 10, dismounting part is ejected from dismounting major axis.
Wherein, push rod 15 through the jackscrew nut 14 in fixation clip 2 and with dismounting major axis on same center line, movable pressing board 3 and gripper shoe 4 are provided with for placing the U-type groove I 5 and U-type groove II 6 of dismantling major axis, and the trench bottom degree of depth of U-type groove I 5 and U-type groove II 6 is below push rod 15 center line.
Movable pressing board 3 is provided with the side plate with side plate groove 13, and side plate is arranged on corresponding with fixation clip 2 of movable pressing board 3, and the suspension bracket 1 of the side of base 9 is connected by bearing.
When part needs dismounting, to be disassembled part wheel part processed with suspension bracket 1 is positioned between fixation clip 2 and movable pressing board 3, dismounting major axis stretches out from the U-type groove I 5 of movable pressing board 3 and gripper shoe 4, U-type groove II 6, and the center of axle and push rod 15 center are on the same line simultaneously; Select suitable side plate to be installed on movable pressing board 3, then regulate adjusting nut 7 to be adjusted to minimum by the gap between movable pressing board 3 and part, fixation clip 2, finally by rotation push rod handle 8, " wheel " and axle are backed down.
Respectively this structure function is made an explanation below.
1. base 9 is for fixing and supporting whole driver-extractor.
2. together with the fixation clip 2 of demountor, movable pressing board 3 to be gone here and there with gripper shoe 4 from the right and left by two pull bars 10, be used for load bearing element dismounting time expansive force and fixing complete machine indeformable.
3. pull bar 10 is provided with coarse-pitch thread screw thread 11, screw thread 11 is provided with adjusting nut 7, and because the thin and thick being disassembled part wheel part processed is different, so can be rotated on pull bar 10 by adjusting nut 7, front and back regulate the distance between movable pressing board 3 and fixation clip 2.
4. pull bar screw thread 11 outside is provided with sleeve pipe 12, for the protection of screw thread 11 and the effect playing top cylinder.
5. movable pressing board 3 is provided with side plate groove 13, because the size being disassembled part is different, so design maximum, for dismantling maximum number part by movable pressing board U-type groove I 5; In case of suitable U-type groove side plate can be selected during smaller parts to be installed in movable pressing board side plate groove 13, not only can play retaining element effect but also movable pressing board 3 can have been reinforced indeformable.
6. fixation clip 2 is provided with jackscrew nut 14, push rod 15 and jackscrew nut 14 precision-fit, by rotating the object of push rod handle 8 come dismounting part.
7. base one jiao is provided with suspension bracket 1, and suspension bracket 1 bottom and base sliding bearing or rolling bearing 16 fix, and can be hung by part move to removed position when being disassembled part and being heavier by mounting hanger on suspension bracket 1.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that detailed description of the invention of the present utility model is only limitted to this, for the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to the utility model and be determined by submitted to claims.Scope of patent protection.
