Description

Technical Field

[0001] The utility model relates to the field of abrasive belt grinding, in particular to an abrasive belt deviation correction induction component. Background Art

[0002] In order to ensure the uniformity of grinding, the sanding belt of the belt grinding equipment needs to move back and forth so that the entire sanding surface can contact the workpiece, thereby maintaining uniform wear on the sanding surface. The distance that the sanding belt moves back and forth is controlled by a sensing mechanism. This type of sensing mechanism is divided into contact and non-contact types. Since the contact sensing mechanism is more worn, a non-contact photoelectric sensing switch is generally used for distance position sensing. However, when the belt grinding equipment is working, the water mist, fine particles and other dirt it produces are easy to adhere to the surface of the photoelectric sensing switch, causing false sensing and making the grinding equipment unable to work normally. Even if compressed air is used to blow the surface of the photoelectric sensing switch continuously, these dirt cannot be completely cleaned. Moreover, in the absence of spray water, the surface of the photoelectric sensing switch is prone to whitening under the continuous blowing of compressed air, further affecting the detection effect. Utility Model Content

[0003] Based on this, the purpose of the utility model is to provide a sanding belt deviation correction sensing component, which has the advantages of good detection effect and long service life.

[0004] A sanding belt deviation correction sensing component includes a support frame, a mounting plate, a photoelectric sensing switch and a cover plate. A through accommodating cavity is opened in the middle of the support frame. The mounting plate is covered at an opening on one side of the accommodating cavity. The cover plate is covered at an opening on the other side of the accommodating cavity to isolate the accommodating cavity from the outside. The sensing end of the photoelectric sensing switch enters the accommodating cavity after passing through the mounting plate and is spaced opposite to the cover plate. The cover plate is made of light-transmitting material.

[0005] The sanding belt deviation correction sensing component described in the utility model has a simple and compact structure. By sealing and protecting the sensing end of the photoelectric sensing switch, it ensures that the photoelectric sensing switch can perform detection normally while preventing dirt such as water mist and fine particles from adhering to the sensing end, thereby improving the detection effect and reducing the cleaning workload.

[0006] Furthermore, there are four photoelectric induction switches arranged around the installation center point of the installation plate, making the structure more compact and improving the sensing accuracy.

[0007] Furthermore, a first sealing ring is sandwiched between the support frame and the cover plate, and a second sealing ring is sandwiched between the support frame and the mounting plate. The sealing ring can improve the airtightness of the structure.

[0008] Furthermore, the support frame is provided with two limiting grooves, which are respectively located on the two sides of the support frame that are in contact with the cover plate and the mounting plate, and the first sealing ring and the second sealing ring are respectively embedded in the two limiting grooves. This structure can limit the sealing ring to prevent the sealing ring from shifting due to machine vibration.

[0009] Furthermore, the first sealing ring and the second sealing ring are in a ring shape surrounding the accommodating cavity. This structure can fully seal the accommodating cavity to prevent water mist from penetrating.

[0010] Furthermore, the installation center point and the midpoints of the support frame, the cover plate, the first sealing ring and the second sealing ring are located on the same axis, which facilitates assembly and makes the structure compact.

[0011] Furthermore, the cover plate, the support frame and the mounting plate are fastened together by screws, thereby achieving a detachable structure for easy maintenance.

[0012] Furthermore, the support frame is rectangular, including two horizontal frames and two vertical frames, the screws include a plurality of horizontal connecting screws and vertical connecting screws, the horizontal connecting screws connect the cover plate to the horizontal frames, the vertical connecting screws connect the cover plate to the vertical frames, and the number of the horizontal connecting screws is greater than the number of the vertical connecting screws. This structure enhances the connection tightness of the upper and lower sides of the support frame, thereby further improving the sealing performance of the upper and lower sides.

[0013] Furthermore, the outer side of the cover plate away from the photoelectric sensor switch is coated with a hydrophobic coating. This structure prevents water mist from condensing on the surface of the cover plate, thereby ensuring the sensing effect.

[0014] Furthermore, the cover plate is made of transparent glass or plastic plate. This structure has good light transmittance and ensures the sensing effect.

[0015] In order to better understand and implement the present invention, the present invention is described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] See also Figure 1 , Figure 1 The utility model discloses an abrasive belt deviation correction sensing component, which is installed inside an abrasive belt grinder. An existing abrasive belt grinder is usually provided with a grinding component inside, which includes a pulley and an abrasive belt sleeved on the outer periphery of the pulley. The abrasive belt deviation correction sensing component is arranged at the front and rear sides of the grinding area (i.e., the working area where the abrasive belt grinds the product) along the grinding direction of the abrasive belt, so as to ensure that the abrasive belt can grind the product accurately.

[0019] The belt deviation correction sensing assembly includes a support frame 1, a mounting plate 2, a photoelectric sensor switch 3 and a cover plate 4. A through-hole accommodating chamber 11 is provided in the middle of the support frame 1. Since spraying and other operations are usually performed in the grinder during the grinding process. Therefore, it is necessary to prevent dirt such as water mist and fine particles from entering the accommodating chamber 11. The mounting plate 2 covers the opening on one side of the accommodating chamber 11, and the cover plate 4 covers the opening on the other side of the accommodating chamber 11, so that the accommodating chamber 11 is isolated from the outside. The cover plate 4, the support frame 1 and the mounting plate 2 are fastened and connected by screws. The cover plate 4 is made of a light-transmitting material, such as a glass plate or a plastic plate with high transparency, smooth surface and high hardness, to avoid scratches caused by cleaning. The outer side of the cover plate 4 away from the photoelectric sensor switch 3 can also be coated with a hydrophobic coating, which improves the liquid flow effect and prevents water droplets from hanging on the cover plate 4 and affecting the sensing accuracy.

[0020] The sensing end of the photoelectric sensor switch 3 passes through the mounting plate 2 and enters the accommodating cavity 11, and is spaced and opposite to the cover plate 4. The photoelectric sensor switch 3 may be provided in plurality. In the present embodiment, the photoelectric sensor switch 3 has four and is arranged around the installation center point of the mounting plate 2. The photoelectric sensor switch 3 may select a counter-radiation structure, that is, the sand belt deviation correction sensing component is a pair of two groups. The second arrangement may be that the photoelectric sensor switches 3 in one group of the sand belt deviation correction sensing components are used for receiving, and the photoelectric sensor switches 3 in the other group of the sand belt deviation correction sensing components are used for transmitting; the photoelectric sensor switches 3 in one group of the sand belt deviation correction sensing components have two for receiving and two for transmitting, and the other group is correspondingly arranged with two for transmitting and two for receiving. The two groups of sand belt deviation correction sensing components correspond to the edges of the sand belt and are mutually reflected, so that the position of the sand belt is monitored by receiving the light beams emitted from the opposite side.

[0021] In order to further improve the sealing performance of the component, a limiting groove 12 is provided on the support frame 1. There are two limiting grooves 12, which are respectively located on the two side surfaces of the support frame 1. The two side surfaces are surfaces that are respectively in contact with the cover plate 4 and the mounting plate 2. A first sealing ring 6 is sandwiched between the support frame 1 and the cover plate 4, and a second sealing ring 7 is sandwiched between the support frame 1 and the mounting plate 2. The first sealing ring 6 and the second sealing ring 7 are respectively embedded in the two limiting grooves 12. The first sealing ring 6 and the second sealing ring 7 can be arranged only in key areas in a strip-shaped structure. Preferably, the first sealing ring 6 and the second sealing ring 7 are in a ring shape surrounding the accommodating cavity 11, thereby protecting the accommodating cavity 11 in all directions. For the convenience of the installation, the center point is located on the same axis as the midpoint of the support frame 1, the cover plate 4, the first sealing ring 6 and the second sealing ring 7.

[0022] The support frame 1 is rectangular, and includes two horizontal frames 13, and two vertical frames 14 connecting the two ends of the two horizontal frames 13. In actual installation, the two horizontal frames 13 are usually located on the upper and lower sides of the photoelectric sensor switch 3, and the two vertical frames 14 are usually located on the left and right sides of the photoelectric sensor switch 3. The screws include a plurality of horizontal connecting screws 51 and vertical connecting screws 52. The horizontal connecting screws 51 connect the cover plate 4 and the horizontal frame 13, and the vertical connecting screws 52 connect the cover plate 4 and the vertical frame 14. The number of the horizontal connecting screws 51 is greater than the number of the vertical connecting screws 52, so that the arrangement of the horizontal connecting screws 51 is more dense, the horizontal frame 13 has a greater pressing force on the sealing ring, and the sealing effect is better. In this embodiment, there are four horizontal connecting screws 51 on each horizontal frame 13, and they are evenly and spaced apart in the horizontal direction; there is one vertical connecting screw 52 on each vertical frame 14, and it is located in the middle of the vertical frame 14.

[0023] During installation, the mounting plate 2 can be connected to the grinding machine chassis or other structures by screws. The structure of the photoelectric sensor switch 3 includes a mounting nut, and the sensing end of the photoelectric sensor switch 3 passes through the mounting plate 2 and is fixedly connected to the mounting plate 2 by the mounting nut. Then, the first sealing ring 6 and the second sealing ring 7 are filled into the limiting groove 12, and the cover plate 4 and the support frame 1 are installed on the mounting plate 2 by screws, and the first sealing ring 6 and the second sealing ring 7 are squeezed and deformed, so that the accommodating cavity 11 can be sealed.

[0024] The sanding belt deviation correction sensing component described in the utility model has a simple and compact structure. The sensing end of the photoelectric sensing switch is sealed and protected to isolate water mist. While ensuring that the photoelectric sensing switch can perform detection normally, it prevents dirt such as fine particles from adhering to and dirtying the sensing end, thereby improving the detection effect and reducing the cleaning workload.
