Description

Technical Field

[0001] The utility model relates to the field of inspection tools, in particular to a handheld screw installation position quick inspection tool. Background Art

[0002] Screws are widely used in machinery, electrical appliances and buildings. They are indispensable industrial necessities in daily life. They are tools that use the physics and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually tighten objects and parts. With the development of more and more precision equipment, the requirements for the installation accuracy of components are getting higher and higher, and more and more professional inspection tools are needed.

[0003] At present, with caliper-type inspection tools, after the screw is in place, the operator needs time to react to disconnect the electric screwdriver because the operator observes that the screw is in place. During the reaction time, the screw continues to rotate. At this time, the screw presses against the pliers of the traditional inspection tool, and the inspection tool cannot be removed. The screw needs to be reversed to restore a certain gap between the screw and the inspection tool before the inspection tool can be removed, which prolongs the time required for inspection and affects the inspection efficiency.

[0032] A hand-held screw installation position, such as Figure 1 As shown, it comprises a housing plate 1 , which is arranged as a pair, with a gap left between the two housing plates 1 .

[0033] like Figure 1 and Figure 2 As shown, a fixing hook 11 is provided at the head of the housing plate 1. During the detection process, the head of the fixing hook 11 clamps the umbrella part of the screw.

[0034] like Figure 1 and Figure 2As shown, a plurality of screws 12 are arranged between the two outer shell plates 1, and the ends of the screws 12 passing through the outer shell plates 1 are threadedly connected with nuts 14 to complete the locking of the screws 12. In the present application, a pad 13 is sleeved on the screw 12, and the pad 13 is located between the two outer shell plates 1. There are three screws 12, two of which are located at the head of the outer shell plate 1, arranged in two layers, and the other screw 12 is fixed at the tail of the outer shell plate 1.

[0035] like Figure 2 and Figure 3 As shown, it includes a steel ball 5, which is movably arranged between the shell plates 1. A limit block 4 is also arranged between the shell plates 1, and both ends of the limit block 4 are inserted into the shell plates 1. The limit block 4 is located below the steel ball 5, and the steel ball 5 is in contact with the top surface of the limit block 4, ensuring that the steel ball 5 can only move in the horizontal direction.

[0036] like Figure 2 and Figure 3 As shown, it includes an unlocking arm 2, which is rotatably connected between the outer shell plates 1, one end of the unlocking arm 2 extends out of the outer shell plate 1, and the other end is against the rotating arm 6 and the steel ball 5.

[0037] like Figure 3 and Figure 5 As shown, the inner side of the unlocking arm 2 is provided with a stop straight surface 21 and a stop surface 1 22, the stop straight surface 21 is located above the stop surface 1 22, when the gauge is in the closed state, the stop straight surface 21 and the end of the unlocking arm 2 are against each other, and the stop surface 1 22 is against the steel ball 5. The inner side of the unlocking arm 2 is provided with a limit curved surface 1 23 and a stop surface 2 24, the limit curved surface 1 23 is located below the stop surface 1 22, and the stop surface 24 is located below the limit curved surface 1 23, when the gauge is in the open state, the limit curved surface 1 23 and the steel ball 5 are against each other, and the stop surface 2 24 is against the bottom surface of the limit block 4.

[0038] like Figure 3 and Figure 4 As shown, a spring pin 3 is provided between the two housing plates 1, and a hook spring 31 is provided between the spring pin 3 and the unlocking arm 2. When the detection is completed, the staff member leaves the hand, and the hook spring 31 rebounds to reset the unlocking arm 2.

[0039] like Figure 3 and Figure 5As shown, it includes a rotating arm 6 and a rotating shaft 61. The rotating shaft 61 is horizontally placed between the outer shell plates 1. The rotating shaft 61 passes through the end of the rotating arm 6 so that the rotating arm 6 is rotatably connected between the outer shell plates 1. The steel ball 5 abuts against the inner end of the rotating arm 6. The inner end of the rotating arm 6 is provided with a stop surface 4 64 and a limiting curved surface 2 65. When the inspection tool is in the open state, the limiting curved surface 2 65 abuts against the steel ball 5. When the inspection tool is in the closed state, the limiting curved surface 2 65 abuts against the steel ball 5, and the stop surface 4 64 abuts against the stop straight surface 21.

The stop surface 3 62 is located on the side of the bending part of the rotating arm 6, and the limiting surface 1 63 is located on the top surface of the bending part of the rotating arm 6.

[0040] Specific working process:

[0041] When the inspection fixture clamps the screw and the inspection fixture is in the open state, the operator presses the unlocking arm 2, the unlocking arm 2 rotates inward, and the unlocking arm 2 and the steel ball escape the interference state. At this time, the stop straight surface 21 and the stop surface 4 64 are against each other, and the steel ball is separated from the contact with the limiting curved surface 1 23. Then the steel ball moves backward and embeds into the stop surface 2 24, and the stop surface 1 22 also separates from the bottom surface of the limiting block. The steel ball moves backward, driving the rotating arm 6 to rotate accordingly, and the limiting curved surface 2 65 contacts the steel ball 5. When it rotates to the extreme position, the limiting surface 1 63 contacts the cushion block 13, preventing the rotating arm 6 from continuing to rotate. After the rotating arm 6 rotates, the distance between the stop surface 3 62 and the fixed hook 11 increases, and the locking state of the screw and the inspection fixture is released. The inspection fixture completes one closure and can be directly taken out. After the operator releases the unlocking arm 2, under the action of the hook spring 31, the unlocking arm 2 and the rotating arm 6 move in the opposite direction to reset.
