Description

Technical Field

[0001] The utility model relates to the fields of industrial production and mechanical manufacturing, and in particular to a positioning mechanism for a pull-rope sensor. Background Art

[0002] The draw rope sensor is a commonly used sensor for measuring force. Its principle is to use a draw rope, spring, movable arm, support arm and resistance strain gauge to form a high-sensitivity and high-precision measurement system. It is widely used in industrial production and mechanical manufacturing and other fields.

[0003] In the existing draw rope sensor, when the draw rope is wound too many times, the wire rope body generates tension due to the tension on the wire rope, and when the rope outlet is small, the draw rope forms an angle with the horizontal line, causing the draw rope to be rubbed against the rope outlet, resulting in wear on the surface of the wire rope, which easily affects the measurement data. Therefore, improvement is needed, and a positioning mechanism for the draw rope sensor is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a positioning mechanism for a pull-wire sensor to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a positioning mechanism of a pull-wire sensor, comprising a device body, wherein the device body comprises:

[0006] The shell has a spring cover fixedly connected to the side of the shell.

[0007] Furthermore, one end of the spring cover is fixedly connected to a wire shaft, and the wire shaft passes through the housing.

[0008] Furthermore, a winding wheel is rotatably connected in the middle of the wire shaft.

[0009] Furthermore, a connecting tube penetrates the outer end of the wire shaft.

[0010] Furthermore, a clamping screw penetrates the connection between the connecting tube and the wire shaft.

[0011] Furthermore, the bottom end of the clamping screw is threadedly connected with a nut.

[0012] Furthermore, one end of the connecting pipe is fixedly connected with a sensor element.

[0013] Furthermore, a front cover is fixedly connected to the right side of the shell.

[0014] Furthermore, a wire outlet is provided at the front end of the front cover, and the wire outlet is in the same horizontal line as the top end of the winding wheel.

[0015] Furthermore, a rubber sleeve is slidably connected to the middle of the wire outlet from left to right, and a pull rope head is snap-connected to one end of the rubber sleeve.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] By setting the clamping screws, nuts and connecting pipes, the sensor element can be fixed to prevent the sensor element from falling due to external impact. By setting the outlet, when the rope pulling head is used for measurement, the position of the wire rope on the winding wheel changes due to the pulling process. At this time, the long hole-shaped outlet can prevent the wire rope from being worn at the outlet position during the pulling process, thereby effectively improving the protection of the device to the wire rope. By setting the rubber sleeve, the surface of the wire rope can be protected, thereby effectively enhancing the practicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
