In order to make the technical solutions in the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.
Example 1
A screw secondary locking, limiting and fixing auxiliary tool comprises an outer shell 1, an inner shell 2, an inner shell limiting structure 6 and a limiting disc 3; as shown in fig. 1, the outer shell 1 is in threaded connection with an electric screwdriver, the inner shell 2 is movably mounted in the outer shell 1, the inner shell limiting structure 6 is mounted on the outer shell 1, and the inner shell 2 is locked by the inner shell limiting structure 6; install elastic construction and screw thread limit structure in the inner shell 2, screw thread limit structure is connected with elastic construction, elastic construction's bottom is connected with inner shell 2, spacing dish 3 movable mounting is in inner shell 2, spacing dish 3 and screw thread limit structure screw-thread fit, screw thread limit structure movable mounting is at elastic construction's free end, and here, elastic construction is preferred to be spacing spring 7.
Further, screw thread limit structure includes stopper 8 and screw thread track 9, stopper 8 is connected with screw thread track 9, stopper 8 is located the expansion end of spacing spring 7, screw thread track 9 and 3 screw-thread fit of spacing dish. Wherein, the thread track 9 is preferably a barrel-shaped structure with threads which can realize thread matching with the limiting disc.
Example 2
As shown in fig. 1 and 2, a slide rail 21 is disposed on an outer side surface of the inner shell 2, a positioning groove 22 is formed on the slide rail 21, and the positioning groove 22 is matched with the inner shell limiting structure 6.
Further, inner shell limit structure 6 includes positioning bolt 61, location separation blade 63 and positioning spring 62, positioning bolt 61 includes positioning nut 611 and positioning stud 612, positioning spring 62 suit is on positioning stud 612, location separation blade 63 is installed on positioning stud 612, positioning spring 62 is located between shell 1 inner wall and the location separation blade 63, location separation blade 63 is located between positioning spring 62 and the inner shell 2 outer wall, the position of slide 21 cooperatees with the position of positioning stud 612, utilizes spring elasticity and the frictional force of location separation blade 63 and the cooperation of positioning stud 612 and slide 21, constant head tank 22 to carry out spacingly to inner shell 2.
Example 3
Further, a sliding module 5 is installed at the bottom of the outer shell 1, and the inner shell 2 is movably installed in the outer shell 1 through the sliding module 5. Preferably, as shown in fig. 3, the sliding module 5 includes a ball 51, and the ball 51 is disposed around the inner housing 2 to ensure that the inner housing 2 is not displaced.
When the auxiliary limiting and fixing tool is locked and attached to the screw for the second time, the outer shell 1 is fixed with the electric screwdriver through the fixing threads 11, then the limiting disc 3 is pushed into the inner shell 2, and as shown in fig. 1, in order to guarantee that the inner shell 2 is stable and does not have deflection, a fixed sliding module 5 is arranged in the bottom of the outer shell 1. When the screws need to be locked twice, the bottom of the inner shell 2 is supported by the same hand to push the inner shell 2 upwards, so that the positioning stud 612 is positioned at the position of the positioning groove 22, and the positioning spring 62 pushes the positioning stop piece 63 fixed with the positioning stud 612, so that the positioning stud 612 is clamped in the positioning groove 22.
And then, the limiting disc 3 is positioned at the edge of the thread track 9, after the screwdriver is started, the limiting disc 3 can continuously go deep along the thread track 9 until the end is reached, and 1/2 locking of the screw is completed. After the 1/2 locking is completed, the electric screwdriver is turned to rotate reversely, so that the limiting disc 3 is separated from the threaded track 9, then the 2 positioning nuts 611 are simultaneously pulled up, and the positioning studs 612 drive the positioning blocking pieces 63 to compress the positioning springs 62, so that the inner shell 2 is separated from the positioning studs 612 and slides down to return to the original position by gravity.
It should be noted that the second locking is normally completed without using a tool for limiting.
If a plurality of screws are required to be locked and attached by 1/2, the positioning stud 612 does not need to be released, and the limiting plate 3 can be continuously used after being withdrawn from the threaded track 9.
In addition, the screw hole needs to be aligned firstly when the locking is carried out, and idle rotation is avoided.
The working principle of the secondary locking auxiliary limiting and fixing tool for the screws is as follows: utilize electric screwdriver torsion certain characteristic, accomplish the fixed management and control of the degree of depth of marcing of screwdriver bit 4 through this frock, can carry out the degree of depth adjustment according to different demands, the screw lock that the cooperation corresponds special parts attaches the requirement.
According to the fixed rotation characteristic of the torsion of the screwdriver head 4, the limiting block 8 is used for blocking the rotation of the screwdriver head 4, the electric screwdriver stops rotating when the blocking force is larger than the torsion, and therefore the fixed stroke locking requirement can be met by blocking the rotation of the screwdriver at a specific stroke position through limiting.
Because the position requirement of the tool is strict, the sliding module 5 can realize that the relative position of the inner shell 2 and the outer shell 1 is in a controllable range by utilizing the rotation characteristic of the ball 51, the conditions of deviation, deflection and the like cannot occur, and the normal use of the tool is ensured.
The fixing thread 11 of the housing 1 realizes the fixing of the housing 1 and the screwdriver, and the thread track 9 is used for the stroke position of the screw locking. The limiting spring 7 assists the threaded rail 9 to move up and down, and the fixing spring assists the fixing stud to clamp and control the position of the inner shell 2 to achieve use and separation of the tool.
The utility model provides a screw secondary lock attaches spacing fixed auxiliary fixtures, need divide the fixed frock of twice fixed requirement preparation to the screw of special parts, solved the production operation and attached half a difficult problem to earlier lock, through cooperating with electric screwdriver, improved the efficiency and the degree of accuracy of operation, effectively guarantee that the operation accords with the operation requirement of special parts, avoid the part that the operation is not standardized to lead to risk such as damage, provide the powerful support for the processing that becomes more meticulous. According to the fixed rotation characteristic of screwdriver head 4 torsion, use spacing dish 3 and hinder screwdriver head 4's rotation with screw thread limit structure, accomplish the use of frock through simple manual cooperation and possess the characteristic of easy operation, provide the assurance to production accuracy and operation convenience, uniformity.
