Description

Technical Field

[0001] The utility model relates to the technical field of dustproof wire-drawing encoders, in particular to a dustproof wire-drawing encoder. Background Art

[0002] A wire encoder is a device that converts mechanical motion into an electrical signal that can be recorded or transmitted. It is mainly used in linear guide systems, hydraulic cylinder systems, testing machines, etc. It consists of a stretchable stainless steel rope wrapped around a threaded hub, which is connected to a precision rotary sensor. The sensor can be an incremental encoder, an absolute (independent) encoder, a hybrid or conductive plastic rotary potentiometer, a synchronizer or a resolver.

[0003] During the use of the existing wire-drawn encoder, when the wire rope is exposed to the outside of the encoder, dust and impurities will adhere to the surface of the wire rope. If the dust is not cleaned, the wire rope will bring the dust into the wire-drawn encoder. Since the wire-drawn encoder is a precision device, the dust that enters will affect the service life of the wire-drawn encoder.

[0004] Therefore, we propose a dustproof wire-drawing encoder that can clean the wire rope of the wire-drawing encoder to prevent external dust from adhering to the outer wall of the wire rope and affecting the precision of the wire-drawing encoder, so as to extend the service life of the wire-drawing encoder. Utility Model Content

[0005] The purpose of the utility model is to provide a dustproof wire encoder to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dust-proof pull-wire encoder, comprising an encoder body, an outlet terminal fixedly mounted on the outer wall of the encoder body, a wire rope slidably arranged inside the outlet terminal, a terminal head fixedly mounted on the end of the wire rope away from the outlet terminal, and a processing component arranged outside the outlet terminal, the processing component comprising a cleaning component arranged outside the wire rope, an auxiliary component being arranged on the side of the cleaning component away from the outlet terminal; the cleaning component comprising a sleeve fixedly mounted on the end of the outlet terminal away from the outer wall of the encoder body, a limit plate being slidably arranged inside the sleeve, a sliding rod being fixedly mounted on the side wall of the limit plate, a cleaning ring being fixedly mounted on the end of the sliding rod away from the limit plate, a spring being sleeved on the outer wall of the sleeve, and a cleaning brush being fixedly mounted on the inner side of the cleaning ring.

[0007] Preferably, the auxiliary component includes a connecting plate fixedly mounted on the outer wall of the cleaning ring, a slider is slidably arranged inside the connecting plate, opposing threaded rods are sleeved inside the slider, a rotating column is rotatably connected to the outer wall of the slider, a guide wheel is fixedly mounted on the outer wall of the rotating column, and a limiting rod is arranged inside the connecting plate.

[0008] Preferably, the limit plate is slidably arranged with the inner wall of the sleeve, and the slide rod is slidably arranged with the inside of the sleeve. Under the restriction of the limit plate, the slide rod can be prevented from sliding out of the sleeve. Under the support of the slide rod and the sleeve, the elastic force generated by the spring on the cleaning ring can be more uniform, so that the vibration cleaning effect of the cleaning brush is better.

[0009] Preferably, there are several cleaning brushes, which are equidistantly distributed on the inner wall of the cleaning ring. The cleaning brushes are made of wear-resistant material, and when the cleaning brushes are in contact with the outer wall of the wire rope, the wear-resistant cleaning brushes can extend their service life.

[0010] Preferably, there are two guide wheels, which are symmetrically distributed about the center line of the connecting plate. The guide wheels are made of rubber anti-slip material and can stably transport the rope.

[0011] Preferably, the slider is slidably arranged inside the connecting plate, and the slider is slidably arranged inside the outer wall of the limit rod. Under their restriction, when the opposite threaded rods rotate, the two sets of guide wheels can be driven to move in opposite or reverse directions to adjust the distance between the guide wheels.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The cleaning brush is used to clean the outer wall of the wire rope, and the cleaning brush is used to clean the outer wall of the wire rope.

[0014] 2. The dust-proof pull-wire encoder is composed of an auxiliary component as one part. When the wire rope needs to be cleaned, it is necessary to ensure that the wire rope and the cleaning ring are set concentrically. With the support of the guide wheel, the wire rope can be clamped, guided and conveyed so that the wire rope is always at the center of the cleaning ring. When some larger wire ropes are wound up, it is necessary to adjust the distance between the guide wheels to better clamp and guide the wire rope. At this time, the opposing threaded rods are rotated. Due to the sliding arrangement of the slider and the connecting plate, the slider moves in the opposite direction under its restriction, so that the rotating column connected to the outer wall of the slider rotates and drives the guide wheel fixedly installed on its outer wall to move accordingly. Due to the sliding arrangement of the other slider and the outer wall of the limit rod, the distance between the two guide wheels can be adjusted under its restriction to accommodate wire ropes of different sizes. This structure can guide the wire rope when it is wound up, and at the same time can make the wire rope always at the center of the cleaning ring, so as to better clean the outer wall of the wire rope.

DETAILED DESCRIPTION

[0022] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0023] Example 1

[0024] A preferred embodiment of a dustproof wire encoder provided by the utility model is as follows: Figures 1 to 6As shown: a dust-proof pull-wire encoder, comprising an encoder body 1; an outlet terminal 2 is fixedly mounted on the outer wall of the encoder body 1; a wire rope 3 is slidably arranged inside the outlet terminal 2; a terminal 4 is fixedly mounted on the end of the wire rope 3 away from the outlet terminal 2; and a processing component 5 is arranged outside the outlet terminal 2, the processing component 5 includes a cleaning component 51 arranged outside the wire rope 3, the cleaning component 51 includes a sleeve 511 fixedly mounted on the end of the outlet terminal 2 away from the outer wall of the encoder body 1, a limit plate 512 is slidably arranged inside the sleeve 511, a slide rod 513 is fixedly mounted on the side wall of the limit plate 512, a cleaning ring 515 is fixedly mounted on the end of the slide rod 513 away from the limit plate 512, a spring 514 is sleeved on the outer wall of the sleeve 511, and a cleaning brush 516 is fixedly mounted on the inner side of the cleaning ring 515.

[0025] In this embodiment, after the wire rope 3 is released, the dust attached to its outer wall needs to be cleaned. When the wire rope 3 is rolled up into the encoder body 1, the outer wall of the wire rope 3 contacts the cleaning brush 516 fixedly installed on the inner wall of the cleaning ring 515. Under the action of multiple cleaning brushes 516, the outer wall of the wire rope 3 can be cleaned. Since the cleaning brush 516 is made of wear-resistant material, it can avoid long-term friction contact between the wire rope 3 and the cleaning brush 516, which affects the service life of the cleaning brush 516. When the wire rope 3 is rolled up, the end 4 fixedly installed at its end contacts the outer wall of the cleaning ring 515 and hits the outer wall of the cleaning ring 515, so that The cleaning ring 515 pushes the slide bar 513 fixed on its outer wall, so that the slide bar 513 moves away from the limit plate 512 fixed on one end of the cleaning ring 515 and slides inside the sleeve 511, so that the outer wall of the cleaning ring 515 is squeezed against the spring 514. Under the elastic restriction of the spring 514, the cleaning ring 515 can be driven to slide back and forth to clean the impurities in the cleaning brush 516 fixed on the inner wall of the cleaning ring 515, so that the cleaning brush 516 can clean the dust attached to the outer wall of the rope 3 more cleanly, and clean the dust attached to the outer wall of the rope 3 to achieve the dust-proof effect of the encoder body 1.

[0026] Furthermore, the limit plate 512 is slidably arranged with the inner wall of the sleeve 511, and the slide rod 513 is slidably arranged with the inside of the sleeve 511. Under the restriction of the limit plate 512, the slide rod 513 can be prevented from sliding out of the sleeve 511. With the support of the slide rod 513 and the sleeve 511, the elastic force generated by the spring 514 on the cleaning ring 515 can be more uniform, so that the vibration cleaning effect of the cleaning brush 516 is better.

[0027] Furthermore, there are several cleaning brushes 516 equidistantly distributed on the inner wall of the cleaning ring 515 . The cleaning brushes 516 are made of wear-resistant material. When the cleaning brushes 516 are in contact with the outer wall of the wire rope 3 , the wear-resistant cleaning brushes 516 can extend their service life.

[0030] The guide wheels 525 are supported by the guide wheels 525, and the guide wheels 525 are supported by the guide wheels 525. When the guide wheels 525 are supported by the guide wheels 525, the guide wheels 525 are supported by the guide wheels 525. When the guide wheels 525 are supported by the guide wheels 525, the guide wheels 525 are supported by the guide wheels 525. When the guide wheels 525 are supported by the guide wheels 525, the guide wheels 525 are supported by the guide wheels 525. When the guide wheels 525 are supported by the guide wheels 525, the guide wheels 525 are supported by the guide wheels 525.

[0031] Furthermore, there are two guide wheels 525 symmetrically distributed about the center line of the connecting plate 521 . The guide wheels 525 are made of rubber anti-slip material and can stably transport the wire rope 3 .

[0032] In addition, the slider 523 is slidably arranged inside the connecting plate 521, and the slider 523 is slidably arranged inside the connecting plate 521 and the outer wall of the limiting rod 526. Under the restriction, when the opposing threaded rods 522 rotate, the two sets of guide wheels 525 can be driven to move in opposite directions to adjust the spacing between the guide wheels 525.

[0033] The above is only an illustrative specific implementation method of the utility model, and is not intended to limit the scope of the utility model.
