Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment, and in particular to cleaning equipment for processing a torque sensor. Background Art

[0002] In order to ensure the accuracy and long-term stability of the torque sensor, it is necessary to use cleaning equipment to remove dirt and impurities on its surface, which helps prevent the torque sensor from errors or failures due to contamination. After the torque sensor is processed, in order to ensure its accuracy and stability, its probe position needs to be cleaned intensively.

[0003] At present, there are some existing technologies that can clean the surface of the torque sensor after the processing is completed. For example, the patent publication number is CN212121068U. Its main technical means is to drive the bristles to drop to a suitable height through a cylinder, and lightly brush the torque angle sensor to remove dust. The spring can provide a certain elastic force, so that the bristles can be close to the torque angle sensor while avoiding excessive pressure, so that the device can perform dust removal processing on the torque angle sensor twice. After analysis, the disadvantage of this technical solution is that it is impossible to deeply clean the probe part of the torque sensor. Only blowing dust or only brushing cannot effectively clean the deep corners of the probe, resulting in dust generated by the deep adhesion of the probe, thereby affecting the normal use of the torque sensor in the later stage. Based on this, the present invention provides a cleaning device for torque sensor processing that has a simple and ingenious structure and can effectively remove dust attached to the deep part of the probe of the torque sensor. Summary of the invention

[0004] The purpose of the present invention is to provide a cleaning device for torque sensor processing in view of the shortcomings of the prior art, so as to solve the technical problem that the deep corners of the probe cannot be effectively cleaned, resulting in dust adhesion in the deep part of the probe.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A cleaning device for processing a torque sensor, comprising:

[0007] A base, on which a clamping assembly for clamping a torque sensor is mounted, and an air intake pipe is connected to the base;

[0008] A dust collecting block is slidably mounted on the base and docked with the probe of the torque sensor. The dust collecting block is driven by a driving source to perform reciprocating linear motion. The dust collecting block is provided with an air passage arranged toward the probe. A wiping cotton in contact with the outer wall of the probe is installed on the dust collecting block; and

[0009] A switching component is installed on the base and is used to switch the connection state between the airway and the air inlet pipe. When the dust block extends into the probe, the switching component controls the connection between the airway and the air inlet pipe, and the airway blows air to the deep part of the probe. When the dust block abuts against the deep part of the probe, the switching component controls the blockage between the airway and the air inlet pipe, and the dust block collects dust in the deep part of the probe.

[0010] As a further solution of the present invention: the switching assembly includes a docking tube, one end of which is connected to the airway through a channel arranged in the dust block, and the other end of which is slidably matched with the air inlet pipe; when the dust block extends into the probe, the docking tube is aligned with the air inlet pipe, and when the dust block abuts against the deep part of the probe, the docking tube and the air inlet pipe are misaligned.

[0011] As a further solution of the present invention: the diameter of the butt joint pipe is smaller than the diameter of the air intake pipe.

[0012] As a further solution of the present invention: there is a gap between the outer wall of the dust block and the inner wall of the probe, a plurality of receiving grooves are arranged on the outer wall of the dust block, and a dust cotton is slidably installed in each receiving groove; when the dust block is extended into the probe, the dust cotton is located in the receiving groove, and there is a gap between the dust cotton and the inner wall of the probe, and when the dust block is in deep contact with the probe, the transmission assembly installed on the dust block drives the plurality of dust cottons to diffuse and contact with the inner wall of the probe.

[0013] As a further solution of the present invention: the transmission assembly comprises:

[0014] Push rods, a plurality of said push rods are slidably installed in the dust block, and connected to the inner wall of the dust block through a reset member, a plurality of said push rods correspond to a plurality of dust cottons one by one, and a guide surface is arranged on said push rods;

[0015] Push blocks, wherein a plurality of the push blocks are respectively fixed on a plurality of dust-absorbing cottons, and a slope that slides with the guide surface is provided on the push blocks, and the push blocks are connected to the inner wall of the dust-absorbing block through an elastic rope; and

[0016] The connecting ring is slidably mounted on the dust-absorbing block, and a plurality of the push rods are fixedly connected to the connecting ring. A stop block is fixed in the base, and the position of the stop block interferes with the moving path of the connecting ring.

[0017] As a further solution of the present invention: the wiping cotton is rotatably installed on the dust-collecting block, and the wiping cotton is connected to the rotating component. When the docking tube and the air intake pipe are misaligned, the air intake of the air intake pipe triggers the rotating component to drive the wiping cotton to rotate and wipe the outer wall of the probe.

[0018] As a further solution of the present invention: the rotating assembly comprises:

[0019] The blade wheel is rotatably mounted at the bottom of the dust block. When the butt joint pipe and the air inlet pipe are misaligned, the air inlet pipe is aligned with the blades on the blade wheel, and the airflow input from the air inlet pipe hits the blades to drive the blade wheel to rotate;

[0020] A driving gear is rotatably mounted in the base and coaxially fixedly connected to the blade wheel, wherein the driving gear meshes with a first gear rotatably mounted in the base; and

[0021] The driven gear is rotatably mounted on the dust-collecting block and fixedly connected to the wiping cotton. The driven gear meshes with a second gear rotatably mounted in the base, and the second gear is coaxially fixedly connected to the first gear.

[0022] Beneficial effects of the present invention:

[0023] (1) In the present invention, when the dust block is driven by the driving source to move to the deep part of the probe, the switching component controls the connection between the airway and the air inlet pipe, and the airway blows air to the deep part of the probe to blow out the dust inside the probe. When the dust block abuts against the deep part of the probe, the switching component controls the airway and the air inlet pipe to be blocked. At this time, the dust block can collect dust from the deep part of the probe, and the wiping cotton can wipe the dust on the outer wall of the probe. By blowing air first and then contacting the dust, the cleaning method can be adaptively adjusted according to the distance between the cleaning part and the deep part of the probe, avoiding the problem of dust accumulation at the corners of the deep part of the probe caused by air blowing dust removal, and at the same time avoiding the damage of high-speed airflow to the components inside the probe during air blowing dust removal;

[0024] (2) In the present invention, when the dust block extends into the probe, the gap between the dust cotton and the inner wall of the probe can discharge the gas blown into the probe; when the dust block abuts against the deep part of the probe, the transmission assembly installed on the dust block drives a number of dust cottons to diffuse and abut against the inner wall of the probe. At this time, there is no gap between the dust cotton and the inner wall of the probe, which can ensure the effective removal of dust in various areas of the inner wall of the probe;

[0025] (3) In the present invention, when the docking pipe and the air inlet pipe are misaligned, the airflow input from the air inlet pipe hits the blades to drive the blade wheel to rotate, and the driving gear rotates synchronously and drives the first gear to rotate. The first gear drives the second gear to rotate synchronously, and then drives the driven gear to rotate, thereby driving the rotation of the wiping cotton. In this way, when the air blowing dust removal is stopped, the wiping cotton rotates to wipe the outer surface of the probe, effectively realizing multi-area cleaning of the inner and outer surfaces of the probe.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-Figure 4 As shown, the present invention is a cleaning device for torque sensor processing, comprising:

[0038] A base 1, on which a clamping assembly for clamping a torque sensor is mounted, and an air intake pipe 3 is connected to the base;

[0039] A dust block 2 is slidably mounted on the base 1 and docked with the probe of the torque sensor. The dust block 2 is driven by a driving source 11 to perform reciprocating linear motion. An air passage 4 arranged toward the probe is provided on the dust block 2. A wiping cotton 8 in contact with the outer wall of the probe is installed on the dust block 2; and

[0040] The switching component 5 is installed on the base 1 and is used for switching the connection state between the airway 4 and the air inlet pipe 3. When the dust block 2 extends into the probe, the switching component 5 controls the connection between the airway 4 and the air inlet pipe 3, and the airway 4 blows air to the deep part of the probe. When the dust block 2 abuts against the deep part of the probe, the switching component 5 controls the blockage between the airway 4 and the air inlet pipe 3, and the dust block 2 collects dust from the deep part of the probe.

[0041] In one case of this embodiment, the clamping assembly includes two clamping blocks for clamping both sides of the torque sensor, and a cylinder for driving the two clamping blocks to move. This is the prior art and this application has not improved it. Therefore, there is no need to disclose its specific mechanical structure and circuit structure, and it does not affect the integrity of this application. The driving source 11 can be a hydraulic cylinder, a cylinder and other components, and can also be other mechanisms that can achieve linear motion. This embodiment does not make specific limitations here.

[0042] During actual application of this embodiment, after the clamping assembly clamps the torque sensor, the probe of the torque sensor is aligned with the dust block 2, and then the driving source 11 drives the dust block 2 to move to the deep part of the probe. During this process, the switching assembly 5 controls the connection between the airway 4 and the air inlet pipe 3, so that the airway 4 blows air to the deep part of the probe to blow out the dust inside the probe. When the dust block 2 abuts against the deep part of the probe, the switching assembly 5 controls the blockage between the airway 4 and the air inlet pipe 3. At this time, the dust block 2 can collect dust in the deep part of the probe, and the wiping cotton 8 wipes the dust on the outer wall of the probe. By blowing first and then contacting the dust, the cleaning method can be adaptively adjusted according to the distance between the cleaning part and the deep part of the probe, thereby avoiding the problem of dust accumulation in the deep corners of the probe due to air blowing dust removal, and at the same time avoiding damage to the components inside the probe caused by high-speed airflow during air blowing dust removal.

[0043] like Figure 1-Figure 4 As shown, as a preferred embodiment of the present invention, the switching component 5 includes a docking tube 501, one end of which is connected to the airway 4 through a channel 502 arranged in the dust block 2, and the other end of which is slidably matched with the air inlet pipe 3; when the dust block 2 is extended into the probe, the docking tube 501 is aligned with the air inlet pipe 3, and when the dust block 2 is in deep contact with the probe, the docking tube 501 and the air inlet pipe 3 are misaligned.

[0044] In one case of this embodiment, the diameter of the butt joint pipe 501 is smaller than the diameter of the air intake pipe 3 .

[0045] It should be noted that the dust block 2 is provided with a distance sensor, which can monitor the distance between it and the deep part of the probe, so as to determine whether the dust block 2 is in contact with the deep part of the probe. This is a prior art and will not be described in detail in this application. The base 1 is provided with an exhaust hole for exhausting the gas input into the base 1 by the intake pipe 3 after the butt joint 501 and the intake pipe 3 are misaligned.

[0046] In actual application of this embodiment, when the driving source 11 drives the dust block 2 to move to the deep part of the probe, the docking tube 501 is aligned with the air inlet pipe 3. During this process, the airflow blown out of the air inlet pipe 3 enters the channel 502 through the docking tube 501, and then blows to the probe through the air duct 4, thereby realizing air blowing dust removal of the probe; when the dust block 2 abuts against the deep part of the probe, the docking tube 501 and the air inlet pipe 3 are misaligned, and the two are blocked, there is no airflow in the docking tube 501, and the air duct 4 no longer performs air blowing dust removal, and the dust block 2 contacts the deep part of the probe and treats the dust on it.

[0047] like Figure 3-Figure 8 As shown, as a preferred embodiment of the present invention, there is a gap between the outer wall of the dust block 2 and the inner wall of the probe, a plurality of receiving grooves 10 are arranged on the outer wall of the dust block 2, and a dust cotton 6 is slidably installed in each receiving groove 10; when the dust block 2 is extended into the probe, the dust cotton 6 is located in the receiving groove 10, and there is a gap between the dust cotton 6 and the inner wall of the probe, and when the dust block 2 is in deep contact with the probe, the transmission assembly 7 installed on the dust block 2 drives the plurality of dust cottons 6 to diffuse and contact with the inner wall of the probe.

[0048] In one case of this embodiment, the dust-absorbing cotton 6 is elastic. After extending out of the accommodating groove 10, the dust-absorbing cotton 6 stretches, and two adjacent dust-absorbing cottons 6 fit together.

[0049] In actual application of this embodiment, when the dust block 2 is extended into the probe, the gap between the dust cotton 6 and the inner wall of the probe can discharge the gas blown into the probe; when the dust block 2 is in deep contact with the probe, the transmission assembly 7 installed on the dust block 2 drives a number of dust cottons 6 to diffuse and contact with the inner wall of the probe. At this time, there is no gap between the dust cotton 6 and the inner wall of the probe, which can ensure the effective removal of dust in various areas of the inner wall of the probe.

[0050] like Figure 3-Figure 8 As shown, as a preferred embodiment of the present invention, the transmission assembly 7 includes:

[0051] Push rods 701, a plurality of push rods 701 are slidably installed in the dust block 2, and connected to the inner wall of the dust block 2 through a reset member 706, a plurality of push rods 701 correspond to a plurality of dust cottons 6 one by one, and a guide surface 702 is provided on the push rods 701;

[0052] Push blocks 708, a plurality of push blocks 708 are respectively fixed on a plurality of dust-collecting cottons 6, and a slope 703 is provided on the push blocks 708 for slidingly cooperating with the guide surface 702, and the push blocks 708 are connected to the inner wall of the dust-collecting block 2 through an elastic rope 705; and

[0053] The connecting ring 704 is slidably mounted on the dust-collecting block 2 , and the plurality of push rods 701 are fixedly connected to the connecting ring 704 . A stop block 707 is fixed inside the base 1 , and the position of the stop block 707 interferes with the moving path of the connecting ring 704 .

[0054] In one case of this embodiment, the reset member 706 can be selected from the following Figure 6 The rubber column shown may also be a spring or other structural component capable of achieving resetting, which is not specifically limited here; the guide surface 702 is located at the bottom of the push rod 701 and faces the push block 708, and the inclined surface 703 is located at the top of the push block 708 and faces the push rod 701.

[0055] In actual application of this embodiment, when the driving source 11 drives the dust block 2 to move deeper into the probe, the push rod 701 moves synchronously with the dust block 2 until the connecting ring 704 abuts against the abutment block 707, and then the driving source 11 drives the dust block 2 to continue to move deeper into the probe until the dust block 2 abuts against the probe. During this process, relative sliding occurs between the connecting ring 704 and the dust block 2. Figure 6 Taking the direction shown as an example, after the connecting ring 704 abuts against the abutment block 707, it descends relative to the dust block 2, so that the guide surface 702 and the inclined surface 703 slide relative to each other and drive the push block 708 to move to the left, so that the dust cotton 6 extends out of the receiving groove 10 and abuts against the inner wall of the probe.

[0056] like Figure 3-Figure 8 As shown, as a preferred embodiment of the present invention, the wiping cotton 8 is rotatably installed on the dust-collecting block 2, and the wiping cotton 8 is connected to the rotating component 9. When the docking tube 501 and the air inlet pipe 3 are misaligned, the air intake of the air inlet pipe 3 triggers the rotating component 9 to drive the wiping cotton 8 to rotate and wipe the outer wall of the probe.

[0057] In one case of this embodiment, the rotating assembly 9 includes:

[0058] The blade wheel 901 is rotatably mounted at the bottom of the dust block 2. When the butt joint 501 and the air inlet pipe 3 are misaligned, the air inlet pipe 3 and the blades on the blade wheel 901 are aligned, and the airflow input from the air inlet pipe 3 hits the blades to drive the blade wheel 901 to rotate;

[0059] A driving gear 902 is rotatably mounted in the base 1 and coaxially fixedly connected to the blade wheel 901, wherein the driving gear 902 is meshed with a first gear 903 rotatably mounted in the base 1; and

[0060] The driven gear 905 is rotatably mounted on the dust-collecting block 2 and fixedly connected to the wiping cotton 8 . The driven gear 905 meshes with the second gear 904 rotatably mounted in the base 1 , and the second gear 904 is coaxially fixedly connected to the first gear 903 .

[0061] The blade wheel 901 is provided with a plurality of blades arranged obliquely.

[0062] In actual application of this embodiment, when the docking tube 501 is misaligned with the air inlet pipe 3, the airflow input by the air inlet pipe 3 hits the blades to drive the blade wheel 901 to rotate, and the driving gear 902 rotates synchronously and drives the first gear 903 to rotate. The first gear 903 drives the second gear 904 to rotate synchronously, and then drives the driven gear 905 to rotate, thereby driving the rotation of the wiping cotton 8. In this way, when the air blowing dust removal is stopped, the wiping cotton 8 rotates to wipe the outer surface of the probe, thereby effectively achieving multi-area cleaning of the inner and outer surfaces of the probe.

[0063] Working principle of the present invention: The above embodiment of the present invention provides a cleaning device for torque sensor processing, which drives the dust block 2 to move to the deep part of the probe through the driving source 11. During this process, the switching component 5 controls the connection between the airway 4 and the air inlet pipe 3, and the airway 4 blows air to the deep part of the probe to blow out the dust inside the probe. When the dust block 2 abuts against the deep part of the probe, the switching component 5 controls the blockage between the airway 4 and the air inlet pipe 3. At this time, the dust block 2 can collect dust in the deep part of the probe, and the wiping cotton 8 wipes the dust on the outer wall of the probe. By blowing first and then contacting the dust, the cleaning method can be adaptively adjusted according to the distance between the cleaning part and the deep part of the probe, thereby avoiding the problem of dust accumulation in the deep corners of the probe due to air blowing dust removal, and at the same time avoiding the damage of high-speed airflow to the components inside the probe during air blowing dust removal.

[0064] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
