[0017] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.

[0018] The embodiment of the utility model relates to a parallelism detection tool for an electromagnetic power-off brake, such as Figure 1-6 As shown, it includes a tooling base plate 1, an electric rotating table 2 is installed on the upper end of the tooling base plate 1, a detachable mounting platform 3 is installed on the upper end of the electric rotating table 2, a circular groove 9 is opened on the upper end of the mounting platform 3, a central cylinder 10 is provided in the middle of the bottom surface of the circular groove 9, and three hole plug columns 11 are arranged around the central cylinder 10 on the bottom surface of the circular groove 9. The upper end of the tooling base plate 1 is located behind the electric rotating table 2 and a vertical plate 8 is vertically installed. The front end of the upper part of the vertical plate 8 is provided with a horizontally arranged extension plate 7, and the lower end of the extension plate 7 is installed with an XY axis adjustment device 6, and the lower end of the XY axis adjustment device 6 is installed with a laser rangefinder 5.

[0019] The electric rotating table 2 and the mounting platform 3 are fixedly connected by fasteners 12, and the mounting platform 3 is designed to be replaceable, which is convenient for later maintenance and replacement.

[0020] Working process: first put the electromagnetic de-energizing brake 4 on the mounting platform 3, align the circular through hole 28 of the electromagnetic de-energizing brake 4 with the central cylinder 10 and insert it, then rotate the electromagnetic de-energizing brake 4 so that the three mounting through holes 27 on the edge of the electromagnetic de-energizing brake 4 are correspondingly inserted into the three hole plugs 11, and cooperate with the inner wall of the circular groove 9 to realize the positioning and installation of the electromagnetic de-energizing brake 4, then turn on the switch of the laser rangefinder 5, adjust the front, back, left and right positions of the laser rangefinder 5 through the XY axis adjustment device 6 to ensure that the detection position falls on the armature 29 in the middle of the brake, then start the electric rotating table 2 to control the rotation of the mounting platform 3, and measure the heights of the armature 29 at four positions respectively. If the heights of the four armatures 29 meet the requirements, the parallelism of the electromagnetic de-energizing brake 4 is qualified, otherwise, it is unqualified.

[0021] Detection principle: This parallelism adjustment tool for electromagnetic power-off brake detects the parallelism of the armature 29 surface to ensure that the distance between the armature 29 surface and the yoke of the electromagnetic brake meets the standard of less than 0.1 mm after power-off, and ensures that the parallelism of the armature 29 surface meets the requirements. In actual engineering, the height of the armature 29 at different positions is measured by the laser rangefinder 5 to determine the parallelism of the armature 29 surface.

[0022] The XY axis adjustment device 6 includes an upper plate 13, a middle adjustment plate 14 and a lower plate 15. The lower end of the upper plate 13 is installed with a middle adjustment plate 14 that slides horizontally, and the lower end of the middle adjustment plate 14 is installed with a lower plate 15 that slides forward and backward. The lower end of the lower plate 15 is installed with a laser rangefinder 5. A limit plate 17 is installed in the middle of the left side and the middle of the rear end of the middle adjustment plate 14. Each limit plate 17 is provided with a long through hole 23. An adjusting bolt 18 is installed in the long through hole 23. A first stopper 19 is installed at the front end of the plate 13, and a first feed knob 20 is screwed on the front end of the middle adjustment plate 14, and one end of the first feed knob 20 presses against the first stopper 19. A second stopper 21 is installed on the right side of the middle adjustment plate 14, and a second feed knob 22 is screwed on the right side of the lower plate 15, and one end of the second feed knob 22 presses against the second stopper 21. One end of the adjusting bolt 18 located on the left side is screwed on the lower plate 15, and one end of the adjusting bolt 18 located at the rear is screwed on the upper plate 13.

[0023] Generally, before adjustment, the middle adjustment plate 14, the lower plate 15 and the laser rangefinder 5 are at the leftmost position. When the position needs to be adjusted to the right, the rear adjustment bolt 18 is loosened, and one end of the first feed knob 20 presses against the first stopper 19. The upper plate 13 remains stationary. The middle adjustment plate 14, the lower plate 15 and the laser rangefinder 5 will slide to the right as the first feed knob 20 rotates. After reaching the desired position, tighten the rear adjustment bolt 18.

[0024] Generally, the lower plate 15 and the laser rangefinder 5 are at the frontmost position before adjustment. When the position needs to be adjusted backward, the adjusting bolt 18 on the left is loosened, and one end of the second feed knob 22 is against the second stopper 21. The upper plate 13 and the middle adjustment plate 14 remain stationary. The lower plate 15 and the laser rangefinder 5 will slide backward as the second feed knob 22 rotates. After reaching the desired position, tighten the adjusting bolt 18 on the left.

[0025] The XY axis adjustment device 6 is a precision adjustment device, and the adjustable distance is small.

[0026] A support seat 24 is installed at the front end of the middle adjustment plate 14 and the right side of the lower plate 15 , and the first feed knob 20 and the second feed knob 22 are respectively screwed on the corresponding support seat 24 .

[0027] A fixing fixture 16 is installed at the lower end of the lower plate 15 , and a through hole 25 is opened in the middle of the fixing fixture 16 for inserting the upper part of the laser rangefinder 5 . A plurality of locking bolts 26 are provided on the side of the fixing fixture 16 , and one end of the locking bolt 26 passes through the through hole 25 to support the laser rangefinder 5 .

[0028] The rotation angle of the electric rotating table 2 is controllable. The electric rotating table 2 can be directly purchased on the market and is an existing component, so it is not elaborated in detail.

[0029] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0030] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0031] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0032] The above is a detailed introduction to the parallelism detection tooling for the electromagnetic power-off brake provided by the present application. This article uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for general technical personnel in this field, based on the ideas of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
