The utility model discloses combine standard tools such as jack, can conveniently accomplish the centering and the support of actuator.
Description
Technical Field
The utility model belongs to the technical field of machinery, a bench test work piece and the instrument of actuator centering, support is related to, concretely relates to strutting arrangement in the middle of actuator that can play the centering effect.
Background
In the prior art, when the actuator needs to be supported in a centering manner, the actuator is horizontally loaded, when the head of the actuator is connected with a workpiece in a centering manner, 1 worker needs to hold the head of the actuator by two hands and gradually lower the head of the actuator, the other worker sees that the head of the actuator is overlapped with a connecting hole (the central height of 2 holes is measured in advance, and the actuator is loaded in the horizontal direction when the overlapping is ensured), then the bolt is quickly put on the actuator, then the head of the actuator is supported by supports such as slightly lower wood blocks, the head of the actuator is held by 1 worker, the other worker gradually adds objects such as thin iron sheets on the supports, the direction of the loading force of the actuator is completely horizontal, and finally the. Because bolt and connecting hole cooperation are accurate, actuator itself is very heavy, and the centering is difficult once only to be accomplished, must use 2 workman, and the workman of embracing the actuator is tired very much, and is difficult to guarantee the precision of actuator loading angle.
Disclosure of Invention
In order to solve the problems existing in the prior art, the utility model provides a strutting arrangement in middle of actuator that can play centering effect, it combines standard tools such as jack, can conveniently accomplish the centering and the support of actuator.
The utility model aims at realizing through the following technical scheme:
the utility model provides a strutting arrangement in middle of actuator that can play centering, includes upper cover, base, installs between upper cover and the base and has many with the screw rod, and the screw rod top is passed through the sleeve pipe and is connected with the upper cover, screw rod bottom and base threaded connection, has still twisted the nut on the screw rod and is used for the butt and promote the sleeve pipe bottom.
The actuator middle supporting device capable of achieving the centering effect is characterized in that a plurality of unthreaded holes and a central unthreaded hole are formed in the bottom of the upper cover, the upper portion of the screw rod is connected with the unthreaded holes of the upper cover through the sleeve, and the sleeve fills gaps between the top cover through holes and the screw rod.
The utility model has the advantages of it is following:
when the actuator will be to work piece horizontal loading, the utility model discloses combine standard tools such as jack, just can conveniently accomplish the centering of actuator and loading work piece with 1 workman to and the support to the actuator during the loading, show the intensity of labour who saves man-hour and workman, and the precision of actuator loading angle is the degree that can't reach with current method.

Detailed Description
The technical scheme of the utility model is described in detail with the attached drawings as follows:
as shown in fig. 3 to 6, an actuator middle support device capable of performing a centering function comprises an upper cover 7, a base 9, 4 screws 6, 4 sleeves 5 and a plurality of nuts.
Four unthreaded holes and a central unthreaded hole are arranged at the bottom of the upper cover 7, and four threaded holes are arranged on the base 9 and correspond to the unthreaded holes of the upper cover 7 in position. 4 screw rods 6 are arranged between an upper cover 7 and a base 9, the upper parts of the screw rods 6 are connected with unthreaded holes of the upper cover 7 through sleeves 5, the sleeves 5 fill gaps between through holes of a top cover and the screw rods, and nuts are screwed on the screw rods 6 and used for abutting against and pushing the bottoms of the sleeves 5; the bottom end of the screw rod 6 is in threaded connection with a threaded hole in the base 9 and is fixed through a nut.
The utility model discloses a theory of operation does:
as shown in fig. 1 and 2, the screw 6 is first screwed into the corresponding threaded hole of the base 9 and fixed with the nut 8, and the rest of the nut 8 is reserved at the bottom of the screw. Then an upper cover 7 and a sleeve 5 are arranged above the screw rod, and the sleeve 5 fills the gap between the through hole of the top cover and the screw rod. The sleeve 5 not only plays a guiding role and protects the screw thread of the screw rod 6 when the top cover moves up and down, but also ensures that the top cover cannot move horizontally. The jack is inserted into the central part of the top cover, and the jack is operated to move the top cover upwards to a position slightly lower than the loading horizontal line of the actuator. Putting actuator 1 on apron 7, continuing to operate the jack top (along arrow direction in fig. 1), stopping the jack after the connecting hole coincidence of actuator head 3 and work piece, then wearing connecting bolt 4, the direction of actuator loading force is complete level this moment, locking connecting bolt 4's nut, all screwing up the remaining nut of every screw rod, the nut on top withstands apron 7, the nut on below is equipped with the tight effect, sleeve pipe 5 has been pushed up by nut 8 and has been got higher than apron 7 this moment. And (3) after the jack is well jacked and the nut is tightened, the jack is disassembled, and the actuator middle supporting device 2 is changed into a middle supporting structure for horizontally loading the actuator from a centering mechanism of the actuator and the loading workpiece.
