Description

Technical Field

[0001] The utility model relates to the technical field of fixing an output shaft and a metal bracket disk, in particular to a clamping structure of an intermodulation motor output shaft and a metal bracket disk. Background Art

[0002] The relationship between the motor output shaft and the metal support plate is an important part of the motor system. The motor output shaft is the key component for transmitting torque and power inside the motor, while the metal support plate usually serves as a fixed support part of the motor or related equipment. The connection and fixation between the two is essential for the normal operation and stability of the motor. The motor output shaft transmits torque and power through rotation to drive other equipment or mechanisms. The connection and fixation with the metal support plate ensures the effective transmission of torque and power, avoiding energy loss and transmission instability.

[0003] There are two existing methods for connecting and fixing the motor output shaft and the metal bracket disk. One is the bolt fixing method: that is, the position and size of the holes on the motor output shaft and the metal bracket disk are pre-designed, and the motor output shaft and the metal bracket disk are fixed together using appropriate bolts (according to the hole size and the required tightening force). Make sure the bolts are tightened to provide sufficient connection strength. The other is the welding method: that is, welding is used to connect the motor output shaft and the metal bracket disk. Welding can provide a very strong connection, but it is necessary to pay attention to the thermal stress and deformation that may be generated during the welding process. However, whether it is bolt fixing or welding, its fixing and disassembly and maintenance are very troublesome. Utility Model Content

[0027] The following is combined with Figure 1 -Attached Figure 7 , further illustrating the specific implementation of the clamping structure of the inter-adjusting motor output shaft and the metal bracket disk of the utility model, overcoming the existing connection and fixing methods between the motor output shaft and the metal bracket disk in the prior art, which are mostly two methods, one is the bolt fixing method: that is, the position and size of the holes on the motor output shaft and the metal bracket disk are pre-designed, and the motor output shaft and the metal bracket disk are fixed together with appropriate bolts. Make sure that the bolts are tightened to provide sufficient connection strength, and the other is the welding method: that is, welding is used to connect the motor output shaft and the metal bracket disk. Welding can provide a very strong connection, but it is necessary to pay attention to the thermal stress and deformation that may be generated during the welding process. However, no matter whether it is fixed by bolts or welding, its fixing, disassembly and maintenance are very troublesome. A clamping structure for the output shaft of an inter-adjustable motor and a metal bracket disk is provided. The output shaft is inserted into the polygonal clamping groove to limit the output shaft along its circumferential direction, so that the output shaft and the metal bracket disk will not rotate relative to each other. Then, the output shaft and the clamping seat are axially locked by a locking mechanism arranged in the rectangular groove, thereby realizing rapid locking and positioning of the output shaft and the metal bracket disk 1, overcoming the problem of troublesome fixing and disassembly using bolt fixing or welding in the prior art.

[0028] The clamping structure of the output shaft of the inter-adjusting motor and the metal bracket plate of the utility model is not limited to the description of the following embodiments.

[0029] Embodiment 1:

[0030] A clamping structure for an intermodulation motor output shaft and a metal support disk, comprising a metal support disk 1 and an output shaft 2, and also comprising a clamping assembly 3, which is arranged on the metal support disk 1 and is used to clamp, position and fix the output shaft 2 and the metal support disk 1;

[0031] The card assembly 3 includes a card seat 301, an annular groove 302 is provided on the outer wall of the card seat 301, a polygonal card groove 311 is provided at the center of the upper surface of the card seat 301, an annular seat 303 is slidably provided in the annular groove 302, a gear ring 304 is welded on the outer wall of the annular seat 303, and a protrusion 305 is provided on the inner wall of the annular seat 303;

[0032] A rectangular groove 309 is provided inside the clamping assembly 3 between the annular groove 302 and the polygonal clamping groove 311, and limiting grooves 310 are provided on the two side walls of the rectangular groove 309. A locking mechanism 307 is provided in the rectangular groove 309 for axially locking the output shaft 2 and the clamping seat 301. A positioning mechanism 308 is also provided on the clamping seat 301 for positioning and fixing the annular seat 303.

[0033] Specifically, the clamping structure of the intermodulation motor output shaft and the metal support disk is such that when in use, the output shaft 2 is inserted into the polygonal clamping groove 311 to limit the output shaft 2 along its circumferential direction, so that the output shaft 2 and the metal support disk 1 will not rotate relative to each other, and then the output shaft 2 and the clamping seat 301 are axially locked through the locking mechanism 307 provided in the rectangular groove 309, thereby realizing rapid locking and positioning of the output shaft 2 and the metal support disk 1, overcoming the problem of troublesome fixing and disassembly in the prior art using bolts or welding.

[0034] Example 2

[0035] Based on the above-mentioned embodiment, the present embodiment further discloses the specific structure of the locking mechanism 307. The outer wall of one end of the output shaft 2 close to the clamping assembly 3 is cut with a cutting surface 201, so that the end of the output shaft 2 close to the clamping assembly 3 forms a multi-deformation structure, which is compatible with the polygonal clamping groove 311. The output shaft 2 is inserted into the polygonal clamping groove 311 to achieve the limit fixation of the output shaft 2 along its circumferential rotation.

[0036] A locking groove 202 for cooperating with the locking mechanism 307 is formed on the outer wall of one end of the output shaft 2 close to the clamping assembly 3. There are three locking grooves 202 in total, and the three locking grooves 202 are distributed in a ring shape with equal intervals.

[0037] The locking mechanism 307 includes a locking block 3071 inserted into the rectangular groove 309, and sliders 3072 are welded on both side walls of the locking block 3071 along the length direction. The slider 3072 is slidably connected with the limiting slide groove 310, and a first spring 3073 is welded between the slider 3072 and the inner wall of the limiting slide groove 310. The end of the locking block 3071 close to the annular seat 303 is an arc structure.

[0038] When the annular seat 303 is pushed to rotate, the protrusion 305 on the annular seat 303 is driven to squeeze one end of the locking block 3071, thereby driving the other end of the locking block 3071 to move into the polygonal snap-in groove 311 and insert it into the locking groove 202 opened on the output shaft 2. At this time, the first spring 3073 is in a stretched state.

[0039] There are three locking mechanisms 307 in total, and the three locking mechanisms 307 are distributed in a ring shape, and the intervals between two adjacent locking mechanisms 307 are equal.

[0040] Specifically, during use, when the output shaft 2 is inserted into the polygonal snap-fit ​​groove 311 and the output shaft 2 is limited along its circumferential direction, it is necessary to axially lock the output shaft 2 and the snap-fit ​​seat 301 through the locking mechanism 307. The specific locking method is to push the annular seat 303 to rotate, drive the protrusion 305 on the annular seat 303 to squeeze one end of the locking block 3071, thereby driving the other end of the locking block 3071 to move into the polygonal snap-fit ​​groove 311, and insert it into the locking groove 202 opened on the output shaft 2, thereby realizing the rapid locking of the output shaft 2.

[0041] Example 3

[0043] Specifically, on the basis of the above embodiment, by pushing the annular seat 303 to rotate, the protrusion 305 on the annular seat 303 is driven to squeeze the locking block 3071 to move and insert into the locking groove 202. At this time, the annular seat 303 needs to be limited, that is, it is achieved by the provided positioning mechanism 308. In the initial state, under the elastic force of the second spring 3083, the limiting tooth block 3084 is driven to be clamped on the gear ring 304 to limit the annular seat 303. When it is necessary to push the annular seat 303 to move, the limiting tooth block 3084 is driven to separate from the gear ring 304 by pulling the limiting plate 3082.
