Description

Technical Field

[0001] The utility model relates to the technical field of steel production equipment, in particular to a zero-position proximity switch fixing device for a high-speed bar multiple-length switch. Background Art

[0002] In the application of high-speed bar multiple-length switches, the 0° angle of the switch is used as the multiple-length shearing angle of the bar. The zero-position proximity switch is installed on the mounting plate of the switch body, and is used to calibrate the 0° angle with the program calculation logic during the start-up of the switch. When the proximity switch senses the zero-position detection stop of the switch shaft, the proximity switch sends a pulse signal. The program collects this signal as the program 0° angle reference value, thereby controlling the angle of the switch, and the actual angle arriving at the site is consistent with the angle calculated by the program.

[0003] When the zero position is offset due to wear of the switch guide tube or deviation and misalignment of the equipment during steel rolling, the switch zero position needs to be adjusted. If it exceeds the adjustment range, it needs to be reinstalled or replaced with spare parts. Figure 5 The mounting plate 200 of the existing zero position proximity opening 4 of the switch body (the original design proximity switch mounting plate) is a straight plate, and the proximity switch 4 is mounted on a straight guide groove on the straight plate that is parallel to the arc tangent of the rotating shaft 7. The mounting position of the proximity switch 4 can be adjusted laterally but cannot be adjusted vertically. After the lateral parallel adjustment, the relative distance between the proximity switch 4 and the center of the zero position detection stop iron 5 changes, and vertical detection cannot be maintained, which affects the stability of the sensing signal. Utility Model Content

[0004] The invention object of the utility model is to provide a high-speed bar multiple-length switch zero position proximity switch fixing device in view of the above problems, which can make the proximity switch installation position adjustable in multiple directions and with a large adjustment angle range.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is:

[0006] A zero-position proximity switch fixing device for a high-speed bar multiple-length switch comprises a fixing plate, a positioning plate and an adjusting bolt assembly, wherein the positioning plate can be fixedly connected to the motor flange of the switch, specifically, the bottom end of the positioning plate can be fixedly connected to the motor flange of the switch by welding or bolting; the fixing plate has a fixing end and a mounting end, wherein the mounting end is convexly arranged relative to the fixing end, and the proximity switch can be fixedly installed on the mounting end, the fixing end of the fixing plate is provided with a straight slot hole extending vertically, and the positioning plate is provided with a guide hole extending horizontally; the adjusting bolt assembly is simultaneously inserted into the straight slot hole and the guide hole, and the fixing end bolt of the fixing plate is connected to the positioning plate, so that the fixing plate is adjustable at the fixed position of the positioning plate.

[0007] The fixing end and the mounting end of the fixing plate form an L-shaped structure, a mounting hole is provided on the mounting end, and the proximity switch is inserted through the mounting hole and fixedly mounted in the mounting hole.

[0008] The guide hole is in a long strip hole structure or an arc hole structure.

[0009] As mentioned above, when the adjusting bolt assembly is loosened, the fixing plate can move left and right along with the guide hole through the bolt, and can also move up and down along with the straight slot hole, so as to adjust the position and orientation angle of the proximity switch, and then adjust the distance from the proximity switch to the stop iron.

[0010] As an option, based on the above solution, in an improved solution, the number of guide holes is at least two and they are arranged at intervals on the positioning plate, the number of adjusting bolt assemblies is the same as the number of guide holes, and at least two adjusting bolt assemblies are respectively inserted into the two guide holes and the straight slot hole. The adjusting bolt assembly includes a bolt and a nut matched with the bolt. In this way, the stability of the connection between the fixing plate and the positioning plate is ensured by a multi-point fixing method.

[0011] As an option, based on the above solution, in the improved solution, when the positioning plate is installed, the center points of at least two guide holes are on the same vertical center line as the center point of the rotating shaft of the switch, and the lateral width of the guide hole is greater than the outer diameter of the rotating shaft of the switch. It should be noted that the design length of the guide hole can be adjusted according to the actual needs on site. Ensure that the fixing plate is symmetrically adjustable based on the center line and adapts to the rotation angle of the stop iron of the switch.

[0012] The utility model of the zero position proximity switch fixing device of the high-speed bar multiple length switch enables the proximity switch to be adjusted vertically up and down on the basis of horizontal left and right adjustment, thereby increasing the adjustment range. Moreover, when adjusting horizontally left and right, the relative distance between the proximity switch and the zero position detection stop iron can be adjusted to remain unchanged, so that the proximity switch and the stop iron are kept in vertical detection, thereby ensuring the stability of the sensing signal.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0020] Example 1

[0021] See also Figure 1 , the left and right are defined as vertical and the top and bottom are defined as horizontal in the figure to facilitate the explanation of this embodiment.

[0022] See also Figure 1-Figure 4 The high-speed bar multiple-length switch zero-position proximity switch fixing device of this embodiment 1 includes a fixing plate 1, a positioning plate 2 and an adjusting bolt assembly 3. The bottom end of the positioning plate 2 can be fixedly connected to the motor flange 6 of the switch 100 by welding or bolting.

[0023] Among them, Figure 4 As shown, the fixed plate 1 has a fixed end 12 and a mounting end 13, and the fixed portion 12 and the mounting portion 13 form an L-shaped structure. A mounting hole is opened on the mounting end 13 of the fixed plate 1, and the proximity switch 4 is inserted into the mounting hole and fixedly installed in the mounting hole and is arranged opposite to the stop iron 5 of the switch 100. The fixed end 12 of the fixed plate 1 is vertically provided with a straight slot hole 11.

[0024] The positioning plate 2 is transversely provided with a guide hole 21, and the adjusting bolt assembly 3 is inserted into the straight slot hole 11 and the guide hole 21 at the same time, and the fixing end 12 of the fixing plate 1 is bolted to the positioning plate, so that the fixing position of the fixing plate 1 on the positioning plate 2 can be adjusted. Specifically, the adjusting bolt assembly 3 includes a bolt 31 and a nut 32 matched with the tightening bolt 31, and the bolt 31 is inserted into the straight slot hole 11 and the guide hole 21 at the same time and is tightened or loosened for adjustment by the nut 32.

[0025] The guide hole 21 can be a long strip hole structure or an arc hole structure, or a combination of one of each. Figure 4As shown, this embodiment 1 is described by taking the guide holes 21 as long strips (such as rectangular) holes and their lateral width is greater than the outer diameter of the rotating shaft 7 of the switch 100. Preferably, the number of the guide holes 21 and the adjusting bolt assembly 3 are both two, and the two guide holes 21 are arranged at intervals on the positioning plate 2. In this way, the stability of the connection between the fixing plate 1 and the positioning plate 2 is ensured by the multi-point fixing method.

[0026] As mentioned above, when the adjusting bolt assembly is loosened, the fixing plate 1 can move left and right along with the guide hole 21, and can also move up and down along with the straight slot hole 11, so as to adjust the position of the proximity switch, and then adjust the distance between the proximity switch and the stop iron. It has a simple structure, is easy to adjust, has a low manufacturing cost, and is easy to replace in the event of wear or damage in the later stage.

[0027] Example 2

[0028] On the basis of Example 1, the structure of the guide holes in Example 2 is different, and both guide holes are arc-shaped structures are further described, and other identical structures are not repeated, and are specifically as follows:

[0029] like Figure 1-Figure 3 As shown, two arc-shaped guide holes are arranged on the positioning plate 2 based on the same center.

[0030] In this way, when the fixing plate is adjusted left and right, the equally arc-shaped guide holes can better guide the bolts and the fixing plate to adjust quickly and smoothly, and the arc-shaped holes can better play the role of positioning and limiting than the rectangular holes, so that the relative distance between the proximity switch 4 and the stop iron 5 of the switch 100 remains unchanged. It should be noted that the design length (lateral width) of the guide hole 21 can be adjusted according to actual needs on site.

[0031] Of course, it can also be that one is an arc-shaped hole and the other is an elongated hole as mentioned above, or one is an outwardly convex arc-shaped hole and the other is an inwardly convex arc-shaped hole, etc., which will not be elaborated here.

[0032] Example 3

[0033] On the basis of Embodiment 1 or 2, the structure of the guide hole of Embodiment 3 is symmetrical, and other identical structures are not repeated here, and are specifically as follows:

[0034] See also Figure 2 and Figure 4 The center points of the two guide holes and the center point of the rotating shaft of the switch are on the same vertical center line. In this way, the fixing plate is symmetrically adjustable on the center line and adapts to the rotation angle of the stop iron of the switch.

[0035] As mentioned above, the installation process of the fixture is as follows: first remove the mounting plate of the original zero-position proximity switch, weld the pre-made positioning plate to the motor flange of the switch, then fix the two plates by passing the adjusting bolt assembly through the straight slot hole of the fixing plate and the guide hole of the positioning plate, and finally install the proximity switch on the mounting hole of the fixing plate, calibrate the position of the proximity switch and the baffle, and tighten the adjusting bolt assembly to fix it. When the zero-position proximity switch needs to be adjusted, loosen the adjusting bolt, and the fixing plate can move left and right with the guide hole, and can also move up and down with the straight slot hole, so as to adjust the position of the proximity switch.

[0036] As mentioned above, the fixing device allows the proximity switch to be adjusted vertically up and down on the basis of horizontal left and right adjustment, thereby increasing the adjustment range. When adjusting horizontally left and right, the relative distance between the proximity switch and the zero position detection stop iron can be adjusted to remain unchanged, so that the proximity switch and the stop iron are kept vertically detected, thereby ensuring the stability of the sensing signal.
