Abstract
Description
Technical Field
[0001] The utility model relates to the field of proximity switches, in particular to a new type of proximity switch induction metal brush plate. Background Art
[0002] The traditional proximity switch is a signal induction element. When the induction part of the proximity switch touches the induction metal plate, the signal is connected, so that the switch signal enters the PLC to participate in some logic controls. The induction distance of the proximity switch is generally designed between 10mm and 50mm. In actual production, the proximity switch is used on the continuous casting slab transfer car. It is necessary for the proximity switch to sense the limit stop iron of each casting stream to pick up the billet. When the transfer car is fully loaded, there will be a certain deformation compared with when it is empty.
[0003] When the traditional proximity switch is installed on the transfer car, due to the deformation of the car body up and down when it is fully loaded, the installation of the proximity switch exists. When the induction part of the proximity switch is adjusted close to the metal induction plate, the proximity switch will be stuck and damaged when the transfer car moves. When the induction part of the proximity switch is adjusted far from the metal induction plate, the proximity switch cannot sense the stop iron. When the weight of the transfer car changes greatly, the mechanical distance up and down of the transfer car will change greatly, and the induction plate is easy to damage the proximity switch due to large deformation. Content of the Utility Model
[0004] To solve the problem that the induction plate is easy to damage the proximity switch due to large deformation, the utility model provides a new type of proximity switch induction metal brush plate, and the technical solution is as follows:
[0005] The new type of proximity switch induction metal brush plate includes a movable seat, the ground, a brush and a clamping structure. The movable seat is arranged on the top of the ground. The brush is arranged inside the clamping structure. Support rods are arranged around the top of the movable seat, and two fixing seats are arranged on the top of the support rods.
[0006] The clamping structure includes an induction plate, a movable plate, a first threaded rod and a first nut. The induction plate is arranged on the top of the back fixing seat. The movable plate is arranged on the side of the front fixing seat close to the induction plate. The number of the first threaded rods is two and they are symmetrically arranged on the left and right sides of the induction plate close to the movable plate. Both of the first threaded rods penetrate and extend to the outside of the movable plate. The number of the first nuts is two and they are respectively arranged on the outer surfaces of the two first threaded rods.
[0007] Adjust the height of the brush according to the deformation of the transfer car. When the transfer car is fully loaded, make the height of the brush higher than the deformation of the transfer car, so as to ensure that when the transfer car undergoes its maximum deformation, it will not collide with the induction plate, and it can effectively avoid the situation that the proximity switch is scratched.
[0008] Preferably, an adjusting structure is provided on the top of the ground. The adjusting structure includes a second threaded rod and a second nut. The number of the second threaded rods is four and they are symmetrically distributed around the top of the ground. All four second threaded rods penetrate and extend to the outer surface of the movable seat. The second nuts are respectively threadedly connected to the top and bottom of the outer surface of the second threaded rod.
[0009] Preferably, limiting holes adapted to the size of the second threaded rods are respectively formed around the inside of the movable seat. The second nuts are respectively in contact with the top and bottom of the outside of the movable seat.
[0010] Preferably, the number of the support rods is two groups. The number of each group of support rods is two and they are symmetrically distributed on the front and back of the top of the movable seat. The two fixed seats are respectively fixedly installed on the tops of the two groups of support rods.
[0011] Preferably, movable holes adapted to the size of the first threaded rods are respectively formed on the left and right sides inside the movable plate. Enough movable space is reserved between the movable plate and the fixed seat.
[0012] Preferably, the first nut is threadedly connected to the outer surface of the first threaded rod. Both of the two first nuts are in contact with the front of the movable plate.
[0013] Preferably, the brush is arranged between the induction plate and the movable plate. The brush is fixed between the movable plate and the induction plate by the force applied to the movable plate by the first nut.
[0014] Preferably, clamping grooves are respectively formed on the left and right sides of the front fixed seat close to the movable plate. One end of a clamping rod extending into the inside of the clamping groove is fixedly installed on the side of the movable plate close to the clamping groove.
[0015] Preferably, the top of the clamping groove is in a hollow shape. The size of the clamping rod is adapted to the size of the clamping groove.
[0016] Twist the first nut to move it to the side away from the movable plate, and then the brush can be conveniently removed for replacement or height adjustment. After the adjustment is completed, reset the first nut to push the movable plate to squeeze and fix the brush. When the height of the induction plate needs to be adjusted, twist the second nut to move it to the side away from the movable seat, and then move the movable seat to the desired height and reset the second nut to make it fit tightly with the movable seat.
[0017] Beneficial effects:
[0018] The beneficial effects produced by adopting the technical solution of the utility model are as follows:
[0019] 1. The new proximity switch senses the metal brush plate. By setting up a brush, the height of the brush is adjusted according to the deformation amount of the billet transfer cart. When the billet transfer cart is fully loaded, the height of the brush is made higher than the deformation amount of the billet transfer cart, so as to ensure that when the billet transfer cart undergoes its maximum deformation, it will not collide with the induction plate, effectively avoiding the situation where the proximity switch is scratched.
[0020] 2. For the new proximity switch sensing metal brush plate, twist the first nut to move it to the side away from the movable plate, then the brush can be easily removed for replacement or height adjustment. After the adjustment is completed, reset the first nut to push the movable plate to squeeze and fix the brush. When the height of the induction plate needs to be adjusted, twist the second nut to move it to the side away from the movable seat, and then move the movable seat to the desired height and reset the second nut to fit and fasten it to the movable seat.

[0028] In this embodiment, the clamping structure can conveniently fix and remove the brush 3, thus facilitating the adjustment and replacement of the height of the brush 3.
[0029] As Figure 2 shown, an adjusting structure is arranged on the top of the ground 2. The adjusting structure includes a second threaded rod 11 and a second nut 12. The number of the second threaded rods 11 is four and they are symmetrically distributed around the top of the ground 2. All of the four second threaded rods 11 penetrate and extend to the outer surface of the movable seat 1, and the second nuts 12 are respectively threadedly connected to the top and the bottom of the outer surface of the second threaded rod 11.
[0030] Specifically, limiting holes adapted to the size of the second threaded rod 11 are respectively opened around the inside of the movable seat 1, and the second nuts 12 are respectively in contact with the top and the bottom of the outside of the movable seat 1, which can prevent the movable seat 1 from tilting and other situations as much as possible.
[0031] In this embodiment, the adjusting structure facilitates the adjustment of the height of the induction plate 6, so that it can be applied to various different usage situations.
[0032] As Figure 1-2 shown, the number of the support rods 4 is two groups, the number of each group of support rods 4 is two and they are symmetrically distributed on the front and the back of the top of the movable seat 1. The two fixing seats 5 are respectively fixedly installed on the tops of the two groups of support rods 4. Movable holes adapted to the size of the first threaded rod 8 are respectively opened on the left and right sides inside the movable plate 7. Enough movable space is reserved between the movable plate 7 and the fixing seat 5. The first nut 9 is threadedly connected to the outer surface of the first threaded rod 8, and both of the two first nuts 9 are in contact with the front of the movable plate 7.
[0033] In this embodiment, the distance between the movable plate 7 and the sensing plate 6 can be adjusted by tightening or loosening the first nut 9, so that the brush 3 can be conveniently fixed or removed.
[0034] like Figure 1 As shown, the first nut 9 is threadedly connected to the outer surface of the first threaded rod 8, and the two first nuts 9 are both in contact with the front of the movable plate 7.

When the blank transfer trolley is moving loaded, the height of the brush 3 is adjusted to be higher than the deformation of the blank transfer trolley, and the adjustment range is controlled within the sensing distance of the proximity switch. Even if the proximity switch can work normally, it avoids the contact between the proximity switch and the sensing plate 6 or the movable plate 7 and causing an accident. By twisting the first nut 9 to move it to the side away from the movable plate 7, the brush 3 can be conveniently removed for replacement or its height can be adjusted. After the adjustment is completed, the first nut 9 can be reset to push the movable plate 7 to squeeze and fix the brush 3. When the height of the sensing plate 6 needs to be adjusted, the second nut 12 can be twisted to move it to the side away from the movable seat 1. After moving the movable seat 1 to the desired height, the second nut 12 can be reset to fit the movable seat 1 until it is tightened.
