Description

Technical Field

[0001] This utility model relates to the field of thread inspection tools, specifically a thread inspection tool for communication components. Background Technology

[0002] Communication components are precision parts. The ends of communication components are machined with threads, which are tapered threads. Before using communication components, it is necessary to check whether the tapered thread size is up to standard.

[0003] A patent search revealed a device, such as publication number "CN218424217U," entitled "A Thread Inspection Tool for Communication Components." This published document describes a device that uses the lifting and lowering of a moving part to allow a rotating tap to inspect the internal threads of a communication component. However, when inspecting the external threads, the operator needs to change the tap type. This method of inspecting both internal and external threads requires repeated tap changes, which is time-consuming and labor-intensive, increasing the workload and reducing the efficiency of thread inspection, thus lowering factory productivity. Therefore, this utility model designs a thread inspection tool for communication components to solve the above problems. Utility Model Content

[0009] Furthermore, the insert block is integrally provided with a limiting hole, which is a through hole design, and the axis of the limiting hole is perpendicular to the axis of the slide rod.

[0010] Furthermore, a limiting pin is threaded through the lower outer end of the rotating rod, and the limiting pin and the limiting hole are disassembled and assembled by plugging in.

[0011] Furthermore, the axis of the slide bar and the axis of the rotating rod on the left are designed to be coaxial, the length of the slot is five centimeters, and the thickness of the gear is five millimeters.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through a simplified mechanical design, allows operators to switch between the internal and external thread detectors on the top left and right sides of the circular plate simply by activating the first motor. The switched internal or external thread detector is then combined with the second motor via a plug and slide bar. Using the second motor, the rotation of either the internal or external thread detector can be controlled independently, enabling the detector to inspect the internal or external threads of communication components. Therefore, by using the device described in this application, not only is the workload and intensity of the operator reduced, but the efficiency of thread inspection for communication components is also improved.

[0015] 2. This utility model, through the design of the limiting function, can lock the state after the slide rod and the left rotating rod are connected, ensuring the stability of the internal or external thread detector when the second motor is linked to rotate. In addition, through the design of gear and slot gear meshing, not only is the synchronization of the gear controlling the slide rod rotation ensured, but also the smooth longitudinal displacement of the slot at the slide rod along the slot tooth area at the gear.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a screw thread inspection tool for communication components includes a base 1. A first motor 2 is fixedly mounted on the middle of the top of the base 1. A rotating shaft 3 fixedly mounted on the top of the first motor 2 rotatably passes through the base 1. A circular plate 4 is fixedly mounted on the top of the base 1. Rotating rods 5 are rotatably connected to the left and right sides of the circular plate 4. A detachable internal thread inspector 6 is mounted on the top of the left rotating rod 5, and a detachable external thread inspector 7 is mounted on the top of the right rotating rod 5. An insertion hole 8 is provided inside the rotating rod 5. A drive assembly 9 is provided inside the base 1. The drive assembly 9 includes a second motor 901 fixedly mounted on the left side of the top of the base 1. A gear 902 is fixedly sleeved on the outside of the output end of the second motor 901. A slide rod 903 is provided on the left side of the top of the base 1. A number of slots 904 are integrally provided inside the slide rod 903. The slots 904 mesh with the gear teeth of the gear 902. An insert block 905 is fixedly mounted on the top of the slide rod 903.

[0025] The first motor 2 is a stepper motor. The first motor 2 stops running after rotating 180 degrees. The second motor 901 is a geared motor. The top view cross-section of the socket 8 and the plug 905 is square. The socket 8 and the plug 905 are disassembled and assembled by plugging.

[0026] First, insert block 905 is inserted into the left-side insertion hole 8. The operator holds the tail end of the internal thread component, which is not threaded. The operator then aligns the bottom surface of the internal thread component with the top surface of the internal thread testing instrument 6, allowing the internal thread component to fit over the instrument. The operator then activates the second motor 901, which drives gear 902 to rotate the slot 904, linkage rod 903, insert block 905, left-side insertion hole 8, left-side rotating rod 5, and internal thread testing instrument 6. The operator then moves the internal thread component downwards, causing the rotating internal thread testing instrument 6 to measure the internal thread component. When testing external thread components, the operator first separates the insertion hole 8 from the insert block 905, then activates the first motor. 2. The first motor 2 drives the rotating shaft 3 to rotate the circular plate 4 180 degrees and then stops. At this time, the circular plate 4 drives the rotating rods 5 on the left and right sides to switch, thereby rotating the internal thread detector 6 on the left to the right. Simultaneously, the external thread detector 7 on the right rotates to the left. The operator then inserts the insert block 905 into the corresponding insertion hole 8, thereby combining the slide rod 903 with the external thread detector 7. The operator then holds the tail end of the external thread component, which has no thread structure, and the operator then makes the bottom surface of the external thread component flush with the top surface of the external thread detector 7, so that the external thread detector 7 fits onto the external thread component. The operator then turns on the second motor 901, and its operation is the same as above, thereby enabling the rotating external thread detector 7 to detect the external thread component. Example

[0027] like Figure 1 , Figure 2 , Figure 3As shown, a controller 10 is fixedly mounted on the outer wall of the base 1. The controller 10 is connected to the first motor 2 and the second motor 901 via wires. The axes of the internal thread detector 6 and the external thread detector 7 are coaxial with the axes of the corresponding rotating rods 5. The insert block 905 has an integrally formed limiting hole 11. The limiting hole 11 is a through hole design. The axis of the limiting hole 11 is perpendicular to the axis of the slide rod 903. The lower end of the rotating rod 5 is threaded through a limiting pin 12. The limiting pin 12 and the limiting hole 11 are connected by insertion. The axis of the slide rod 903 is coaxial with the axis of the left rotating rod 5. The length of the slot 904 is five centimeters, the thickness of the gear 902 is five millimeters, and the two rotating rods 5 are designed to be parallel to each other, with a distance of five centimeters between each pair of the two rotating rods 5.

[0028] According to the operation method in Embodiment 1, when the slide bar 903 drives the insert block 905 to move longitudinally along the direction of the base 1, the slot 904 moves longitudinally along the direction of the teeth of the gear 902, ensuring the stability of the meshing of the gear 902 and the slot 904. After the insert block 905 is inserted into the insertion hole 8, the operator rotates the limiting pin 12 to insert the limiting pin 12 into the limiting hole 11. In this way, the state after the slide bar 903 and the left rotating rod 5 are combined is locked, ensuring the stability of the slide bar 903 and the left rotating rod 5 rotating synchronously.
