Description

Technical Field

[0001] The utility model belongs to the technical field of reducer installation, and particularly relates to a reducer installation stop end face detection tool with adjustable side clearance. Background Art

[0002] In the prior art, the motor usually needs to cooperate with the reducer to output torque. Specifically, the power input shaft of the reducer is connected to the motor shaft through a spline, so that the rotation output by the motor is first transmitted to the reducer, and then the output shaft of the reducer is connected to the load. During the installation, the reducer is usually locked with the motor by bolts. In order to ensure the stable transmission of power after installation, the coaxiality of the power input shaft of the reducer and the motor shaft must be ensured. The flatness of the end face of the reducer installation stopper has a great influence on the coaxiality of the power input shaft of the reducer and the motor shaft. Therefore, before the installation, the flatness of the end face of the reducer installation stopper needs to be detected.

[0003] At present, the flatness of the reducer mounting spigot end face is usually measured with a micrometer. During the measurement process, the micrometer is simply installed at a certain position, and then the head of the micrometer is brought into contact with the reducer mounting spigot end face, and then the reducer is rotated so that the reducer mounting spigot end face rotates relative to the micrometer. This measurement method has a large error because the micrometer is not installed based on the reducer input shaft. Utility Model Content

DETAILED DESCRIPTION

[0055] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0056] Example:

[0057] The utility model provides a reducer installation stop end face detection tool with adjustable side clearance. Figure 1-Figure 14 As shown, it includes a base, a ring 400, a driving member and a micrometer 600, wherein:

[0058] The base is a seat body, which has a circular mounting hole, and the input shaft of the reducer can be inserted into the circular mounting hole, and a slide groove is provided in the hole wall of the circular mounting hole. The ring 400 is rotatably mounted in the circular mounting hole, and a slider 410 is fixedly arranged on the outer ring wall of the ring 400, and the slider 410 is slidably placed in the slide groove. Since the slider 410 is placed in the slide groove, the ring 400 can rotate in the circular mounting hole, and a first tooth portion 420 is arranged on the inner ring wall of the ring 400, and the first tooth portion 420 is used to be keyed with the spline on the input shaft of the reducer. The driving member is mounted on the base, and the driving member is connected to the slider 410, and the driving member is used to drive the slider 410 to slide in the slide groove, so that the ring 400 rotates in the circular mounting hole, and the micrometer 600 is mounted on the base, that is, the sliding process of the driving member driving the slider 410 in the slide groove is actually a rotational movement of the slider 410 in the slide groove centered on the central axis of the ring 400.

[0059] When the tool is used to detect the flatness of the end face of the reducer installation stop, the ring 400 is first put on the reducer input shaft so that the first tooth portion 420 is keyed to the spline on the reducer input shaft. Of course, in order to enable the ring 400 to be put on the reducer input shaft, the tooth width of the first tooth portion 420 is smaller than the tooth spacing on the spline. When the first tooth portion 420 is keyed to the spline, there is a side gap between the teeth of the first tooth portion 420 and the side wall of the gap between the teeth of the spline. Then, the driving member is used to drive the slider 410 in the slide groove. The ring 400 is rotated in the middle, thereby causing the ring 400 to rotate relative to the reducer input shaft, driving the teeth of the first tooth portion 420 to press against the teeth of the spline, thereby eliminating the above-mentioned side clearance, so that the ring 400 and the reducer input shaft are stably connected together, that is, the two can rotate synchronously and at the same speed, and then the head of the micrometer 600 is attached to the end face of the reducer mounting stop, and then the base is rotated by hand to make the tool rotate together with the reducer input shaft, and the value of the micrometer 600 is read during the rotation to obtain the measurement result.

[0060] Through the above structure, the detection tool provided by the utility model takes the input shaft of the reducer as a reference when measuring the flatness of the end face of the reducer mounting stop, and eliminates the installation side clearance of the tool on the input shaft of the reducer through an ingenious structure. In this way, the flatness of the end face of the reducer mounting stop can be measured more accurately.

[0061] In order to conveniently rotatably mount the ring 400 in the circular mounting hole of the base, and conveniently rotatably place the slider 410 in the slide groove, an optional implementation of this embodiment is as follows:

[0062] The above-mentioned base is composed of a first annular seat body 100 and a second annular seat body 200. The first annular seat body 100 and the second annular seat body 200 are both annular block structures. The first annular seat body 100 and the second annular seat body 200 are stacked together. The inner holes of the first annular seat body 100 and the second annular seat body 200 are of equal diameter and the same. After being stacked together, the inner hole of the first annular seat body 100 and the inner hole of the second annular seat body 200 correspond to form the above-mentioned circular mounting hole, and a first groove 110 is opened on the end surface of the first annular seat body 100 and the second annular seat body 200 that are in contact with each other, and a second groove 210 is opened on the end surface of the second annular seat body 200 and the first annular seat body 100 that are in contact with each other, and the first groove 110 and the second groove 210 are assembled to form a slide groove.

[0063] The micrometer 600 is installed on the end surface of the first annular seat body 100 away from the second annular seat body 200. Since the installation of the micrometer 600 belongs to the prior art, it will not be described in detail here.

[0064] During assembly, the slider 410 on the ring 400 is first placed in the second groove 210 on the second annular seat 200, and then the first annular seat 100 is covered on the second annular seat 200, so that the first groove 110 and the second groove 210 are opposite to each other to form the above-mentioned slide groove, and then the first annular seat 100 and the second annular seat 200 are locked by a locking member. The base of this structure has the advantages of being easy to disassemble and assemble, simple in structure, and convenient for installing the above-mentioned ring 400.

[0065] Of course, the above-mentioned base can also be a block including a mounting opening at one end and a retaining ring bolted to the base, the above-mentioned sliding groove is opened on the side wall of the mounting opening, the ring 400 is rotatably placed in the above-mentioned mounting opening, the slider 410 is slidably placed in the above-mentioned sliding groove, and then the retaining ring is used to retain the ring 400 in the mounting opening, and the inner hole of the retaining ring is adapted to the above-mentioned ring 400.

[0066] Optionally, the locking member includes a bolt 300. A positioning through hole 240 is provided on the second annular seat body 200, and the positioning through hole 240 penetrates the second annular seat body 200. A positioning column 140 is fixed on the first annular seat body 100. Specifically, the positioning column 140 is fixed on a side end face where the first annular seat body 100 and the second annular seat body 200 are attached, and the positioning column 140 corresponds to the positioning through hole 240. During installation, the positioning column 140 is inserted into the positioning through hole 240. A screw hole 141 is provided at one end of the positioning column 140 which faces away from the first annular seat body 100, and a bolt 300 is screwed into the screw hole 141. It should be noted that the positioning column 140 is accommodated in the positioning through hole 240 and does not extend out of the positioning through hole 240. The threaded section of the bolt 300 is inserted into the positioning through hole 240 from the side facing away from the first annular seat body 100 and then screwed into the screw hole 141. The nut of the bolt 300 presses against the second annular seat body 200 from the side facing away from the first annular seat body 100.

[0067] Of course, a countersunk hole located at the edge of the positioning through hole 240 is provided on the side of the second annular seat body 200 facing away from the first annular seat body 100, and the nut of the bolt 300 is placed in the countersunk hole.

[0068] With the help of the positioning column 140, the first annular seat body 100 and the second annular seat body 200 can be accurately installed to ensure that the first groove 110 and the second groove 210 are matched to form the above-mentioned slide groove. Optionally, in this embodiment, the number of positioning columns 140 provided on the first annular seat body 100 is multiple, and similarly, the number of positioning through holes 240 provided on the second annular seat body 200 is also multiple, and the multiple positioning columns 140 are respectively inserted into the multiple positioning through holes 240, and each positioning column 140 is connected to one of the above-mentioned bolts 300, so that the first annular seat body 100 and the second annular seat body 200 are firmly connected together.

[0069] In order to make it more convenient for the staff to rotate the base, in this embodiment, a handle 150 is also installed on the first annular base body 100, so that the staff can hold it when rotating the base, thereby applying a rotational force on the base. The handle 150 can be bolted to the end surface of the first annular base body 100 that is away from the second annular base body 200 by screws, or can be fixedly connected to the first annular base body 100 by welding or bonding, as long as the base can be rotated.

[0070] An optional implementation of the present embodiment is as follows: the driving member includes a screw 500, a threaded through hole 120 connected to the first groove 110 is provided in the first annular seat body 100, the screw 500 is screwed to the threaded through hole 120, and an external hexagonal rotating head is provided at one end of the screw 500 located outside the threaded through hole 120 to rotate the screw 500. The slider 410 is provided with an inclined surface 411, which is opposite to the threaded through hole 120. Thus, when the screw 500 is rotated, the head end of the screw 500 can be driven in and out of the slide groove. After the head end of the screw 500 enters the slide groove, the head end of the screw 500 will be directly pressed on the inclined surface 411. When the screw 500 is further rotated so that the head end of the screw 500 goes deeper into the slide groove, the screw 500 will exert pressure on the inclined surface 411, thereby driving the slider 410 to slide sideways, and further driving the slider 410 and the ring 400 to rotate.

[0071] In this embodiment, a ball bearing can be rollingly installed at the head end of the screw 500 to avoid direct contact between the head end of the screw 500 and the inclined surface 411. Instead, the ball bearing directly contacts the inclined surface 411, thereby reducing the friction force exerted on the inclined surface 411 by the screw 500, thereby making it easier to drive the slider 410 to slide in the slide groove.

[0072] Of course, the above-mentioned driving member can also be an electric telescopic rod, which is installed on the first annular seat body 100. In this case, the above-mentioned threaded through hole 120 is a through hole without threads, and a push rod is slidably installed in the through hole. The push rod is connected to the telescopic end of the electric telescopic rod. When the electric telescopic rod is extended or retracted, the push rod can be driven to push the inclined surface 411.

[0073] More preferably, in this embodiment, an elastic member is installed between the slider 410 and the side groove wall of the slide groove. When the screw 500 abuts against the inclined surface 411 and applies pressure to the inclined surface 411, the slider 410 slides in the slide groove and squeezes the elastic member. At this time, the elastic member accumulates elastic potential energy. When the force applied by the screw 500 on the inclined surface 411 of the slider 410 decreases or disappears, the elastic member releases the elastic potential energy, thereby driving the slider 410 to reset.

[0074] Specifically, the elastic member is a spring 430. In this case, a convex column 220 is provided on the side groove wall of the slide groove, and the spring 430 is sleeved outside the convex column 220 to position and install the spring 430. The two ends of the spring 430 are respectively supported on the side groove wall of the slide groove and the outer wall of the slide groove. Of course, the elastic member can also be an inflatable bag.

[0075] In order to place the ring 400 more stably in the circular mounting hole, an optional implementation of this embodiment is as follows:

[0076] The tool also includes a first stop ring 700 and a second stop ring 800, the inner holes of the first stop ring 700 and the second stop ring 800 are both adapted to the inner hole of the above-mentioned ring 400, a first plug block 710 is arranged on the outer ring wall of the first stop ring 700, a first slot 130 is opened on the end surface where the first annular seat body 100 and the second annular seat body 200 are attached, and the first plug block 710 is clamped in the first slot 130. A second plug block 810 is arranged on the outer ring wall of the second stop ring 800, a second slot 230 is opened on the end surface where the second annular seat body 200 and the first annular seat body 100 are attached, and the second plug block 810 is clamped in the second slot 230.

[0077] When assembling the tool, first insert the second insert block 810 on the second limiting ring 800 into the second slot 230 on the second annular seat body 200 to install the second limiting ring 800 on the second annular seat body 200, then place the slide groove of the ring 400 into the second groove 210 on the second annular seat body 200, then insert the second insert block 810 on the first limiting ring 700 into the first slot 130 on the first annular seat body 100 to install the first limiting ring 700 on the first annular seat body 100, and then buckle the first annular seat body 100 on the second annular seat body 200, so that the first annular seat body 100 is inverted. 0 corresponds to the above-mentioned second groove 210, and finally the first annular seat body 100 and the second annular seat body 200 are locked by using a locking member. After installation, the two end surfaces of the ring 400 are respectively connected to the first limiting ring 700 and the second limiting ring 800, that is, the above-mentioned first limiting ring 700 and the second limiting ring 800 are respectively placed on both sides of the ring 400, so as to limit the ring 400 from both sides in the axial direction, so that the ring 400 can be placed in the above-mentioned circular mounting hole more stably, and the first limiting ring 700 and the second limiting ring 800 can also support the rotation of the ring 400.

[0078] It is easy to understand that the first limiting ring 700 and the second limiting ring 800 are fixed relative to the base, and the ring 400 can rotate relative to the base to adjust the side clearance between the first tooth portion 420 and the spline of the reducer input shaft.

[0079] More preferably, in this embodiment, the inner ring hole of the first stop ring 700 and the inner ring hole of the second stop ring 800 are both provided with a second tooth portion 900, and the second tooth portion 900 is used to be keyed with the spline on the reducer input shaft. Of course, the tooth width of the second tooth portion 900 is smaller than the tooth clearance of the spline on the reducer input shaft, so that the first tooth portion 420 can be keyed with the spline on the reducer input shaft. In this case, when the tool is mounted on the reducer input shaft, the second tooth portion 900 on the first stop ring 700, the first tooth portion 420 on the ring 400, and the second tooth portion 900 on the second stop ring 800 will be keyed with the spline on the reducer input shaft, so that the tool can be connected to the reducer input shaft to form a whole. Of course, there is a side clearance between the first tooth portion 420 and the second tooth portion 900 and the spline. After keying, the ring 400 and the first tooth portion 420 are driven to rotate by the above-mentioned driving member, thereby eliminating the above-mentioned side clearance.

[0080] In order to reduce the friction between the ring 400 and the first limiting ring 700 and the friction between the ring 400 and the second limiting ring 800, an optional implementation of this embodiment is as follows:

[0081] A first planar thrust bearing 720 is installed between the ring 400 and the first limiting ring 700, and a second planar thrust bearing 820 is installed between the ring 400 and the second limiting ring 800. At this time, along the axial direction of the ring 400, the first limiting ring 700, the first planar thrust bearing 720, the ring 400, the second planar thrust bearing 820 and the second limiting ring 800 in this embodiment are stacked together in sequence.

[0082] After installation, the bottom wall of the slider 410 is not in contact with the bottom wall of the slide groove. Thus, when the screw 500 applies pressure on the inclined surface 411, the slider 410 can be driven to slide in the slide groove more easily, thereby driving the ring 400 to rotate in the circular installation hole more easily.

[0083] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
