Detailed Description

Fig. 1 shows a schematic view of a motor shaft used in a small-system, high-power air compressor, for which ensuring accuracy of the total length is important, and once the shaft is too long, it cannot be smoothly installed inside the compressor; and the rotating shaft is too short, so that the required accessories cannot be installed on the rotating shaft. In addition, in order to facilitate the installation of the fittings on the rotating shaft and the disassembly and assembly of the rotating shaft, it is also generally required to respectively punch center holes at both ends of the rotating shaft.

From the above, it is apparent that when a normal lathe chuck, such as a three-jaw chuck, is used, only one end of the rotating shaft can be machined, and the other end can be machined, so that the total length of the rotating shaft cannot be ensured. In order to solve the problem, the application provides a motor rotating shaft positioning device, which can process two ends of a rotating shaft simultaneously after the rotating shaft is arranged on the device, so that the total length of the rotating shaft is ensured.

The first clamping plate 12 is provided with a first clamping groove 121 with an opening at a lower portion, the first clamping groove 121 is located above the first positioning groove 111, and the first clamping groove 121 is used for clamping an upper portion of one end of the rotating shaft from above, so that one end of the rotating shaft is fixed in the first positioning groove 111, and in this embodiment, the cross section of the first clamping groove 121 is in an inverted V shape, but in other embodiments, the cross section of the first clamping groove 121 may be in a circular arc shape corresponding to the outer diameter of the rotating shaft. After the first clamping plate 12 is pressed down on the rotating shaft, the first locking member 13 holds the first clamping plate 12 relatively fixedly in this position (i.e., clamping position), preventing the first clamping plate 12 from moving. In this embodiment, the first locking member 13 is a bolt, the upper portion of the bolt is screwed on the first connecting frame 112 at the upper portion of the first positioning seat 11, and the lower end of the bolt is connected with the first clamping plate 12, so that the relative fixing of the first clamping plate 12 can be achieved by controlling the bolt to rotate on the first connecting frame 112. Obviously, other structures, such as a common cylinder, an oil cylinder, etc., can be adopted for the first locking member 13, and the movement of the piston rod controls the up-and-down movement of the first clamping plate 12, so as to realize the clamping action of the rotating shaft.

As shown in fig. 2, the second positioning assembly 20 includes a second positioning seat 21, a second clamping plate 22 provided above the second positioning seat 21, and a second locking member 23 for holding the first clamping plate in a clamped position when clamped, the second positioning seat 21 is provided with a second positioning groove 211 having an upper opening, the second positioning groove 211 is used for supporting and positioning the bottom of the other end of the rotating shaft, and in the present embodiment, the section of the second positioning groove is V-shaped, but in other embodiments, the second positioning groove may be circular arc-shaped corresponding to the outer diameter of the rotating shaft. The second clamping plate 22 is provided with a second clamping groove 221 with an open lower part, the second clamping groove 221 is located above the second positioning groove 211, and the second clamping groove 221 is used for clamping the upper part of the other end of the rotating shaft from above, so that the other end of the rotating shaft is fixed in the second positioning groove 211, in the embodiment, the section of the second clamping groove 221 is in an inverted V shape, but in other embodiments, the section of the second clamping groove 221 is in a circular arc shape corresponding to the outer diameter of the rotating shaft.

As shown in fig. 3, in the present embodiment, the lower portion of the bolt is provided with a first connecting portion recessed inward in the circumferential direction so that the lower portion of the bolt forms an annular groove, the upper end of the first clamping plate 12 is formed with a second connecting portion, an opening portion 122 opening upward and a mounting portion 123 provided below the opening portion 122 and having a width larger than that of the opening portion 122, and the bolt and the first clamping plate 12 are detachably connected by the first connecting portion and the second connecting portion. Specifically, the opening 122 is fitted in the recess, and the bolt is fitted in the mounting portion 123 at a position below the recess, so that both are fixed in the vertical direction, but both can be moved in the horizontal direction (e.g., the front-rear direction in fig. 3), thereby facilitating the removal of the first clamping plate 12 from the first locking member 13.

It should be noted that the second clamping plate 22 and the second locking member 23 may be detachably connected as described above, which is not described herein.

It is noted that the spindle may have different specifications, i.e. different axial lengths, and therefore the distance between the first positioning assembly 10 and the second positioning assembly 20 is preferably adjustable, for example, the adjusting member 30 is disposed between the first positioning assembly 10 and the second positioning assembly 20, in this embodiment, the adjusting member 30 is a screw, one end of the screw is rotatably disposed on the first positioning assembly 10, and the linear output end of the screw is fixedly connected to the second positioning assembly 20, so that when the screw rotates, the linear output end will drive the second positioning assembly 20 to move, thereby changing the distance between the first positioning assembly 10 and the second positioning assembly 20 to adapt to the spindle with different specifications. Further, for convenience in rotating the screw, a hand wheel 31 (see fig. 2) may be provided at a first end of the screw.

It should be noted that, the adjusting member 30 may also be a combination of a stepper motor and a gear rack, and the gear is driven to linearly move on the rack by the rotational movement of the stepper motor, so as to change the distance between the first positioning assembly 10 and the second positioning assembly 20.

On the basis of adopting the adjusting component 30, a guide component is generally required to be added to ensure that the second positioning component 20 does not deviate in the moving process, in this embodiment, a guide plate 40 is arranged below the second positioning component 20, a guide groove 41 is arranged on the guide plate 40, a guide protruding block 213 is arranged below the second positioning seat 21, and the guide protruding block 213 extends into the guide groove 41, so that when the second positioning component 20 moves, the second positioning component is ensured to move along the direction of the guide groove 41, and deviation is prevented, namely, the first positioning groove 111 and the second positioning groove 121 are ensured to be on the same straight line.

On the contrary, when the screw 51 is screwed upward, the second positioning seat 21 and the guide plate 40 can be separated from each other, so that the second positioning seat 21 can be driven to move on the guide plate 40 by the adjusting part 30.
