However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0017] This application provides a device for detecting the coaxiality of a motor mount, such as... Figures 1-6 As shown, it includes a base plate 1, on which a first mounting plate 2 is provided, and a second mounting plate 3 is provided on one side of the first mounting plate 2.

[0018] The first mounting plate 2 and the second mounting plate 3 are coaxially provided with clamping rings 4, the clamping ring 4 comprises an outer sleeve ring 41 and an inner sleeve ring 42, the outer sleeve ring 41 is arranged outside the inner sleeve ring 42, and the outer sleeve ring 41 and the inner sleeve ring 42 are rotationally arranged around the axis thereof, a plurality of arc-shaped holes 411 are arranged in the circumferential direction on the outer sleeve ring 41, a plurality of sliding grooves 421 corresponding to the number of arc-shaped holes 411 are arranged in the circumferential direction on the outer side of the inner sleeve ring 42, the length direction of the sliding groove 421 is consistent with the radial direction of the inner sleeve ring 42, and a sliding rod 422 is movably arranged in the sliding groove 421, the axis direction of the sliding rod 422 is parallel to the axis direction of the inner sleeve ring 42, the inner side end of the sliding rod 422 extends towards the center of the inner sleeve ring 42 and is provided with a connecting plate 423, and the lower side of the connecting plate 423 is perpendicularly provided with a clamping plate 424 for clamping and fixing the motor base, and the outer side end of the sliding rod 422 is slidably arranged in the corresponding arc-shaped hole 411.

[0019] The other side of the first mounting plate 2 is provided with a detection assembly 5, the detection assembly 5 comprises a lifting plate 51 arranged in the vertical direction, the lifting plate 51 is movably arranged along the length direction thereof and is provided with a mounting seat 52, the mounting seat 52 is used for mounting a dial gauge 53, after the dial gauge 53 is mounted, the measuring rod thereof is arranged in the vertical direction and the axis thereof is arranged on the extension line of the diameter of the clamping ring 4, so that the measuring rod of the dial gauge 53 is perpendicular to the tangent direction of the measured point of the inner surface of the motor base, thereby reducing the possible error in the detection of the dial gauge 53.

[0020] In application, the motor base to be detected needs to be clamped and fixed first, that is, the two ends of the motor base are clamped by the clamping rings 4 on the first mounting plate 2 and the second mounting plate 3; specifically, the outer sleeve ring 41 is rotated, the inner sleeve ring 42 does not rotate, the sliding rod 422 is slidably arranged in the arc-shaped hole 411, and the clamping plate 424 is moved along the radial direction of the inner sleeve ring 42, so as to clamp and fix one end of the motor base.

[0021] Then the position of the dial gauge 53 needs to be adjusted, the dial gauge 53 is moved to the cross section of the measured inner surface, the measuring head of the dial gauge 53 is in contact with the measured inner surface, and there is a compression amount of 1-2 turns, specifically, the dial gauge 53 is moved along the axis direction of the clamping ring 4 by moving the mounting seat 52 along the length direction of the lifting plate 51, and the dial gauge 53 is raised and lowered by raising and lowering the lifting plate 51.

[0022] The clamping ring 4 is rotated, that is, the outer sleeve ring 41 and the inner sleeve ring 42 are rotated at the same speed, the clamping ring 4 drives the motor base to rotate slowly and uniformly for one turn, and the fluctuation of the dial gauge pointer is observed, and the coaxiality error at the position is recorded and calculated.

[0023] The upper and lower inner holes of the motor base are detected according to the above steps, and the coaxiality errors of the upper and lower inner holes of the motor base can be calculated.

[0024] Specifically, as shown in Figure 2 and Figure 5 The edge of the outer sleeve ring 41 extends inwardly with a fixing ring 43, the inner end of the fixing ring 43 does not exceed the inner end of the first mounting plate 2 or the second mounting plate 3 where it is located, the inner wall of the fixing ring 43 is in sliding contact with the outer wall of the inner sleeve ring 42, and the part of the circumference of the fixing ring 43 that extends beyond the outer end of the first mounting plate 2 or the second mounting plate 3 is arrayed with fixing holes 431 that are opened through, and the fixing holes 431 are used to install screws to avoid relative movement of the outer sleeve ring 41 and the inner sleeve ring 42, improve the stability of the clamping of the clamping ring 4 on both ends of the motor base, and avoid the relative movement of the outer sleeve ring 41 and the inner sleeve ring 42 after completing the clamping and fixing of both ends of the motor base, which causes the clamping plate 424 to move and leads to unstable clamping. The reason why multiple fixing holes 431 are provided is that the technician can choose the most convenient fixing hole 431 to install when installing the screw in the fixing hole 431, which can effectively avoid the relative movement of the outer sleeve ring 41 and the inner sleeve ring 42.

[0025] Specifically, as shown in Figures 1-3 In the first mounting plate 2, the part of the inner sleeve ring 42 that extends beyond the inner end of the first mounting plate 2 is coaxially sleeved with a gear ring 425, the gear ring 425 is engaged with a gear 21, the gear 21 is driven to rotate by a first motor, and the first motor is installed on the first mounting plate. The arrangement of the gear ring 425 and the gear 21 can drive the rotation of the inner sleeve ring 42 through the engagement of the gear ring 425 and the gear 21, and after installing the screw at the fixing hole 431, the rotation of the inner sleeve ring 42 will drive the rotation of the outer sleeve ring 41, thereby realizing the rotation of the entire clamping ring 4. On the other hand, when the outer sleeve ring 41 is rotated and the inner sleeve ring 42 does not rotate, the engagement of the gear ring 425 and the gear 21 locks the inner sleeve ring 42, at which time the technician only needs to manually rotate the outer sleeve ring 41 to realize the movement of the clamping plate 424 in the radial direction of the inner sleeve ring 42.

[0026] Specifically, as shown in Figure 1 and Figure 4As shown in the second mounting plate 3, the part of the inner collar 42 protruding from the inner end of the second mounting plate 3 is provided with a positioning groove 426 in the radial direction thereof, and a plurality of positioning grooves 426 are circumferentially arranged. The inner side of the second mounting plate 3 extends inwardly to form a positioning platform 31, which is located above the inner collar 42. A positioning rod 32 is vertically movably arranged on the positioning platform 31, and the axis of the positioning rod 32 is on the extension line of the diameter of the inner collar 42. The positioning rod 32 is used to be inserted into the positioning groove 426 to prevent the inner collar 42 from rotating. A spring 33 is arranged on the positioning rod 32 and above the positioning platform 31. When the spring 33 is in a natural state, the positioning rod 32 is located outside the positioning groove 426, and the inner collar 42 is not in a locked state. When the outer collar 41 is rotated without rotating the inner collar 42, the end of the positioning rod 32 is inserted into the positioning groove 426 by pressing it downward, so that the inner collar 42 is locked. At this time, only the technician needs to manually rotate the outer collar 41 to realize the movement of the clamping plate 424 in the radial direction of the inner collar 42. The reason why the positioning groove 426 is provided with a plurality of positioning grooves is that the technician can select a positioning groove 426 that is most convenient for inserting the positioning rod 32, so as to lock the inner collar 42.

[0027] Specifically, as shown in Figure 1 and Figure 6 , the mounting seat 52 is coaxially connected with a fixing rod 53 away from one side of the first mounting plate 2. The other end of the fixing rod 53 is connected with a fixing plate 54. The fixing plate 54 is threadedly arranged on a screw rod 55 arranged in parallel to the length direction of the lifting plate 51. The screw rod 55 is driven to rotate by a second motor. The screw rod 55 is rotatably arranged on the lifting plate 51. The lifting plate 51 is driven to move by a telescopic rod 56.

[0028] Specifically, as shown in Figure 1 and Figure 6 , the lifting plate 51 is vertically provided with a vertical plate 57 on the side facing the first mounting plate 2. The fixing rod 53 movably passes through the vertical plate 57 to provide support for the fixing rod 53, reduce the possibility of bending of the fixing rod 53 during use, and improve the accuracy of the dial gauge 53 during detection.

[0029] Specifically, as shown in Figure 1 and 4 , the second mounting plate 3 is movably arranged along the length direction of the bottom plate 1. The bottom plate 1 is provided with a T-shaped guide rail 11 along the length direction thereof. The bottom plate 1 is provided with a T-shaped groove at the bottom. The bottom plate 1 is slidably fitted in the T-shaped guide rail 11 through the T-shaped groove.

[0030] In application, the above-mentioned is only the preferred embodiment of the present application, and is not used to limit the present application. Obviously, those skilled in the art can make various modifications and changes to the present application without departing from the spirit and scope of the present application.
