Description

Technical Field

[0001] This invention belongs to the technical field of relay manufacturing process equipment, and in particular, it is a rotary contact switch rotation angle measuring device. Background Technology

[0002] Relays are common electronic components in various electronic instruments and electronic devices. A certain type of relay has a built-in rotary contact switch (7). The rotary contact switch (7) includes a base (71), an output terminal (72), a fixed pin (73), a rotating pin (74), and a reset pin (75). When a torque is applied to the rotating pin (74), the rotating pin (74) can rotate relative to the fixed pin (73), thereby driving the conductive sheet inside to switch between multiple contacts, realizing the connection and disconnection control of the electrical connection between the corresponding contacts. In mass production, after the rotary contact switch (7) is manufactured, it needs to be inspected. One of the inspection items is to detect the rotation angle of the rotating pin (74) relative to the fixed pin (73) to avoid defective products from flowing into subsequent production processes or into the market.

[0003] For example, patent document CN109239504B discloses a testing method for the timing waveform of the contact on / off angle of a rotary changeover switch, including the following steps: 1) The microprocessor of the signal data processing subsystem acquires the contact on / off signal of the rotary changeover switch through the microcontroller's general-purpose input / output port and obtains the angle signal acquired in real time by the angle acquisition module; 2) The microprocessor sends data packets to the host computer according to the set data format. The host computer eliminates interference signals during device operation through an adaptive algorithm and accurately measures the timing waveform of the contact on / off angle of the rotary changeover switch; 3) The host computer's neural network identifies the type of rotary changeover switch to be tested, matches standard waveforms from the database, compares them with the measured waveform, obtains manufacturing errors, and determines whether it is qualified. However, this patented technology still cannot allow testing personnel to intuitively read the rotation angle of the changeover switch, and the structure is complex. The operation of the device depends on electricity, and it cannot work in the event of a power outage. Therefore, there is an urgent need to develop a new type of angle measurement device. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a rotary contact switch rotation angle measuring device.

[0005] The present invention is achieved through the following technical solutions.

[0006] This invention provides a rotary contact switch rotation angle measuring device, including a turntable and a ruler, the turntable and the ruler being rotatably connected, the ruler having multiple scale lines printed on its surface, the ruler being fixedly connected to a positioning block, the positioning block having a positioning groove on its surface, and the turntable being fixedly connected to a limiting block, the limiting block having a limiting groove on its surface.

[0007] The measuring disc is also fixedly connected to the indicator plate.

[0008] The measuring disc is also fixedly connected to the support leg.

[0009] The rotary contact switch rotation angle measuring device also includes a base, a pressure block, and a clamping bolt. The clamping bolt is screwed to the base and passes through the pressure block.

[0010] The base is also slidably connected to the anti-rotation block.

[0011] The base is also screwed to a stop bolt, which passes through the anti-rotation block.

[0012] The number of legs is multiple, and the multiple legs are evenly distributed in an array around the perimeter of the ruler plate.

[0013] The turntable is circular in shape, and the limiting block is fixed to the inner circumferential surface of the turntable.

[0014] The measuring disc is circular in shape, and the positioning block is fixed to the inner circumferential surface of the measuring disc.

[0015] The ruler is circular in shape, with multiple scale lines evenly distributed around the central axis of the ruler, and the angle between two adjacent scale lines is 1°.

[0016] The beneficial effects of this invention are as follows: When measuring personnel need to perform inspections, the fixed pin is first fitted into the positioning groove, and the rotating pin is fitted into the limiting groove. Then, a rotational torque is applied to the turntable, causing the rotating pin to rotate relative to the fixed pin. At the same time, when the turntable rotates relative to the scale, the measuring personnel can intuitively read the corresponding reading of the turntable rotation angle from the surface of the scale, which facilitates the measuring personnel's measurement operation. This invention has the characteristics of simple structure and convenient operation. Attached Figure Description

[0021] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0022] like Figures 1 to 3 As shown, this invention provides a rotary contact switch rotation angle measuring device, including a turntable 5 and a scale 4. The turntable 5 and scale 4 are rotatably connected. Multiple scale lines are printed on the surface of the scale 4. The scale 4 is also fixedly connected to a positioning block 6, whose surface has a positioning groove. The turntable 5 is also fixedly connected to a limiting block 8, whose surface has a limiting groove. Using the technical solution of this invention, the rotary contact switch 7 has a fixed pin 73 and a rotating pin 74. When the measuring personnel need to perform testing, firstly, the fixed pin is fitted into the positioning groove, and then the rotating pin is fitted into the limiting groove. Then, a rotational torque is applied to the turntable, causing the rotating pin to rotate relative to the fixed pin. Simultaneously, as the turntable rotates relative to the scale, the measuring personnel can intuitively read the corresponding reading of the turntable rotation angle from the scale surface, facilitating the measuring operation. This invention has the characteristics of simple structure and convenient operation.

[0023] Specifically, the scale plate 4 is also fixedly connected to the indicator plate 9. The scale plate 4 is also fixedly connected to the support leg 11. The rotary contact switch rotation angle measuring device also includes a base 3, a pressure block 1, and a clamping bolt 12. The clamping bolt 12 is screwed to the base 3 and passes through the pressure block 1. Thus, the support leg 11 or the scale plate 4 is clamped by the pressure block 1, so that the support leg 11 provides stable support for the scale plate 4, thereby facilitating the tester to apply rotational torque to the turntable 5.

[0024] In addition, the base 3 is slidably connected to the anti-rotation block 2. The base 3 is also screwed to the stop bolt 10, which passes through the anti-rotation block 2. There are multiple support legs 11, which are evenly distributed in an array around the perimeter of the scale plate 4.

[0025] In addition, the turntable 5 is circular in shape, and the limiting block 8 is fixed to the inner circumference of the turntable 5. The ruler 4 is circular in shape, and the positioning block 6 is fixed to the inner circumference of the ruler 4. The ruler 4 is circular in shape, and multiple scale lines are evenly distributed around the central axis of the ruler 4, with an inclination angle of 1° between two adjacent scale lines.
