Description

Chain missing piece detecting device

Technical field

The present invention relates to the field of chain assembly technology, and in particular, to a chain missing component detecting device.

Background technique

The chain consists of outer sheets, inner sheets, small tubes, large tubes and pin assemblies. Due to the variety of parts and the number of parts, there may be missing parts during automatic assembly, which affects the efficiency and quality of chain assembly. Nowadays, it is often necessary to manually chain the chain. The inspection is carried out, but the manual inspection has a large error, and the labor cost is high, and the inspection efficiency is low. Therefore, it is urgent to design a detection device that can check the missing parts of the chain.

Summary of the invention

In view of the above-mentioned deficiencies of the prior art, the main object of the present invention is to overcome the deficiencies of the prior art, and to disclose a chain missing component detecting device, comprising a body, a detecting block, a sensor, an elastic member and a driving device, wherein The detecting block is slidably connected to the body through the elastic member, the sensor is disposed on the body, and the driving device is coupled to the body to drive the body to reciprocate.

Further, one end of the body has a positioning portion.

Further, a sliding slot is disposed on the body, and the detecting block is disposed in the sliding slot.

Further, the elastic member is a spring.

Further, the driving device is one of a cylinder, a cylinder, and a screw motor.

The beneficial effects obtained by the invention:

The chain missing component detecting device of the invention has the advantages of simple structure, convenient operation, quick determination of whether the chain is missing, high accuracy, and ensures the assembly and assembly quality of the chain.

Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1, a chain missing component detecting device of the present invention comprises a body 1, a detecting block 2, a sensor 3, an elastic member 4 and a driving device, wherein the detecting block 2 is slidably connected to the body 1 via an elastic member 4. The sensor 3 is disposed on the body 1, and a driving device (not shown) is coupled to the body 1 to drive the body 1 to reciprocate.

In one embodiment, the body 1 has a positioning portion 11 for positioning and fixing the chain when detecting whether the chain is missing. The positioning portion 11 can extend into the middle of the two pins to achieve positioning.

In addition, the detecting block 2 and the body 1 can be slidably connected by the cooperation of the sliding rail and the slider. Preferably, the body 1 is provided with a sliding slot 12, and the detecting block 2 is disposed in the sliding slot 12, so that the detecting block 2 can be The horizontal movement is more stable and can make the detection device of the present invention smaller.

The sensor 3 is fixed on the body 1, the detecting block 2 is close to the sensor 3, and the sensor 3 sends a signal to the control device to indicate that there is no missing piece. Otherwise, if no signal is transmitted to the control device, the missing piece is indicated; of course, if the sensor 3 and the detecting device Block 2 is set at a relatively long distance, and the distance between the sensor 3 and the detection block 2 can be reduced by providing an extension block on the detection block 2.

The drive device can be one of a cylinder, a cylinder and a screw motor.

Again, as shown in FIG. 1, in a specific embodiment, the elastic member 3 can use a thrust spring. One end of the thrust spring is connected to the body 1 and the other end is connected to the detecting block 2 so that the detecting block is always at the end of the body 1.

As shown in FIG. 2, in another specific embodiment, the elastic member 3 can use a tension spring, one end of the tension spring is connected with the end of the body 1, and the other end is connected with the detecting block 2, so that the detecting block is always in the body 1. Ends.

In the chain missing detecting device of the present invention, the chain to be detected is stationary, the driving device pushes the body 1 to move to the chain to be detected, and the positioning portion 11 extends into the chain to position the chain.

When the body 1 is moved by a specified distance, since the chain is not missing, the detecting block 2 is pushed up and approaches the sensor 3, and the sensor 3 senses that the detecting block 2 is close, giving the control device a signal indicating that the missing piece is missing. .

When the body 1 is moved by a specified distance, since the detecting block 2 has no object to block it, the detecting block 2 does not approach the sensor 3, and the sensor 3 does not transmit a signal to the control device, indicating that the missing component is present.

The above are only the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the modifications and equivalents of the present invention are intended to cover the scope of the present invention. among.
