[0036] The upper portion of base beam 1 is provided with two supporting rollers 4 in parallel and at intervals, the supporting rollers 4 are vertically arranged with the base beam 1, and the two ends of the supporting rollers 4 are rotationally connected with the base beam 1.

[0037] In the embodiment, the connecting mode of the supporting rollers 4 and the base beam 1 can be one of a bearing, a bearing seat or a shaft sleeve, so that the supporting rollers 4 can freely rotate on the base beam 1.

[0038] One end of the support roller 4 is provided with a limiting sleeve 5, the limiting sleeve 5 is sleeved on the support roller 4 and is fixedly connected with the support roller 4, the to-be-measured stator 6 is fixedly placed on the support roller 4 during detection, the two support rollers 4 support the to-be-measured stator 6, and one end of the to-be-measured stator 6 is in contact with the limiting sleeve 5, thereby forming axial positioning.

[0039] The base beam 1 is also fixedly provided with a detection device 7 for detecting the size of the to-be-measured stator 6, as shown in the figure, the detection device 7 comprises a vertical guide rail 701 arranged vertically, the lower end of the vertical guide rail 701 is fixedly connected to the outer side of the base beam 1 near one end of the limiting sleeve 5, and a vertical sliding block 702 is slidingly connected to the vertical guide rail 701. Figure 3

[0040] Specifically, a groove is formed in the vertical guide rail 701, a vertical sliding groove 703 is formed in the vertical sliding block 702 at a position corresponding to the groove of the vertical guide rail 701, the size of the vertical sliding groove 703 is adapted to the size of the groove of the vertical guide rail 701, and the two form a sliding pair, so that the vertical sliding block 702 is slidingly connected to the vertical guide rail 701.

[0041] A vertical surface of the vertical guide rail 701 in contact with the groove bottom of the vertical sliding groove 703 is provided with a positioning through hole 705, and a positioning screw 706 is installed in the positioning through hole 705, the positioning screw 706 is used to fix the vertical sliding block 702 at a proper position on the vertical guide rail 701.

[0042] In the embodiment, the positioning through hole 705 is a plurality of threaded through holes uniformly and evenly arranged in the vertical direction, correspondingly, the thread specification of the positioning screw 706 corresponds to the threaded through hole, and the distance between the adjacent two threaded through holes is less than the height dimension of the vertical sliding block 702, so that the vertical sliding block 702 can cover at least one threaded through hole when moving on the vertical guide rail 701, so that the vertical sliding block 702 can be fixed at a proper position on the vertical guide rail 701 according to different sizes of the stator.

[0043] When the vertical sliding block 702 is sliding to a height position corresponding to the stator end face during use, the positioning screw 706 is installed in the threaded through hole corresponding to the position of the vertical sliding block 702 and is tightened, the end of the positioning screw 706 abuts against the groove bottom surface of the vertical sliding groove 703, thereby positioning the vertical sliding block 702.

[0044] ​In addition to this embodiment, the positioning through hole 705 can also be an elongated hole with a smooth inner wall. The elongated hole is opened in the vertical direction and covers the movement range of the vertical slider 702. An auxiliary positioning hole is opened at the bottom of the vertical sliding groove 703 at a position corresponding to the positioning through hole 705. The auxiliary positioning hole is threaded. The length of the positioning screw 706 should ensure that the bolt head contacts the vertical surface of the vertical guide rail 701 after tightening. The friction of the two contact surfaces is used to fix the vertical slider 702 in the required position.

[0045] In use, slide the vertical slider 702 to the height position corresponding to the stator end face, align the positioning screw 706 with the auxiliary positioning hole and tighten it so that the bolt head is pressed against the vertical guide rail 701. In order to ensure that the positioning is firm and reliable, a serrated washer is also provided on the vertical guide rail 701 that contacts the positioning screw 706 to increase the friction between the two contact surfaces.

[0046] The upper and lower surfaces of the vertical slider 702 are also provided with oil injection holes 704, which are connected to the vertical sliding groove 703. By injecting an appropriate amount of lubricating oil into the oil injection holes 704, the sliding of the vertical slider 702 becomes smoother.

[0047] A horizontal sliding groove 707 is provided on the opposite side of the vertical sliding groove 703 on the vertical slider 702. The horizontal sliding groove 707 is perpendicular to the vertical sliding groove 703. A horizontal slider 708 is slidably installed in the horizontal sliding groove 707. Figure 5 As can be seen, a sliding protrusion 709 is fixedly provided on the side of the horizontal slider 708 corresponding to the vertical slider 702. The outer dimensions of the sliding protrusion 709 are adapted to the shape of the horizontal sliding groove 707 on the vertical slider 702. The two form a sliding pair, so that the horizontal slider 708 and the vertical slider 702 are slidably connected.

[0048] like Figure 4 and Figure 6 As shown, a spring limiting plate 711 is fixedly installed in the transverse sliding groove 707 near the end of the probe 6 to be measured, and a slider limiting plate 712 is detachably installed on the transverse slider 708 near the end of the probe 6 to be measured. The slider limiting plate 712 extends to one side of the sliding protrusion 709.

[0049] The sliding protrusion 709 has a U-shaped groove inside. One end of the U-shaped groove is open and the other end is closed near the slider limiting plate 712. The closed end of the U-shaped groove is fixedly connected to a return spring 710. When the slider limiting plate 712 abuts against the side of the sliding protrusion 709, the return spring 710 abuts against the spring limiting plate 711 and is in a compressed state.

[0050] When assembling, first slide the horizontal slider 708 into the horizontal sliding groove 707, the free end of the return spring 710 abuts against the spring limiting plate 711, push the horizontal slider 708 to compress the return spring 710, so that the horizontal slider 708 is close to one end of the measuring sub 6 beyond the side surface of the vertical slider 702, at this time, the slider limiting plate 712 is assembled to the horizontal slider 708, and the assembly is completed.

[0051] When the horizontal slider 708 is pushed to move close to the measuring sub 6, the return spring 710 is compressed, and the spring limiting plate 711 simultaneously plays a limiting role, after the external force is removed, the horizontal slider 708 is returned under the action of the return spring 710, at this time, the slider limiting plate 712 plays a limiting role, the slider limiting plate 712 and the spring limiting plate 711 cooperate with each other to ensure that the horizontal slider 708 will not displace excessively and be separated from the horizontal sliding groove 707.

[0052] As shown in Figure 5 The side of the horizontal slider 708 opposite to the sliding block 709 is provided with a detection sliding groove 713, the detection sliding groove 713 is parallel to the sliding block 709, and the first detection scale 715 is arranged above the slot of the detection sliding groove 713, and the 0 point scale of the first detection scale 715 is located at the midpoint position.

[0053] The detection guide rail 714 is slidably installed in the detection sliding groove 713, specifically, the detection guide rail 714 is provided with a groove matched with the shape of the detection sliding groove 713, the groove and the detection sliding groove 713 form a sliding pair, one end of the detection guide rail 714 is slidably connected to the horizontal slider 708, and the other end extends close to the measuring sub 6.

[0054] The detection guide rail 714 is slidably installed in the detection sliding groove 713, specifically, the detection guide rail 714 is provided with a groove matched with the shape of the detection sliding groove 713, the groove and the detection sliding groove 713 form a sliding pair, one end of the detection guide rail 714 is slidably connected to the horizontal slider 708, and the other end extends close to the measuring sub 6.

[0055] The detection guide rail 714 is slidably installed in the detection sliding groove 713, specifically, the detection guide rail 714 is provided with a groove matched with the shape of the detection sliding groove 713, the groove and the detection sliding groove 713 form a sliding pair, one end of the detection guide rail 714 is slidably connected to the horizontal slider 708, and the other end extends close to the measuring sub 6.

[0056] Before the detection operation, the 0 point scale on the second detection scale 716 is aligned with the 0 point scale on the first detection scale 715, and then the height position of the vertical slider 702 is adjusted according to the inner ring diameter size of the measured sub 6, so that the detection rail 714 is aligned with the inner ring of the measured sub 6 in the up-down direction, the positioning screw 706 is tightened to lock the vertical slider 702, and then the measured sub 6 is loaded from the end away from the detection device 7, and the end of the outer ring of the measured sub 6 is in contact with the end of the limiting sheath 5 away from the detection device 7. At this time, if the axial size of the inner ring of the measured sub 6 is greater than the axial size of the outer ring, as shown in Figure 8 , the detection rail 714 will be pushed out, and the transverse slider 708 will remain stationary under the action of the slider limiting plate 712, and the first detection scale 715 and the second detection scale 716 will be out of alignment.

[0057] If the measured sub is assembled, as shown in Figure 7 , the 0 point scales on the first detection scale 715 and the second detection scale 716 are in alignment, the rail limiting plate 717 at the end of the detection rail 714 is gently pushed, and if the detection rail 714 cannot be pushed, it indicates that the axial size of the inner ring of the measured sub 6 is equal to the axial size of the outer ring. If the detection rail 714 can be pushed, that is, Figure 9 , the transverse slider 708 is displaced under the action of the detection rail 714, indicating that the axial size of the inner ring of the measured sub 6 is smaller than the axial size of the outer ring. After the detection is completed, the detection rail 714 is loosened, and under the action of the return spring 710, the transverse slider 708 drives the detection rail 714 to return to the original position.

[0058] During the detection process, the measured sub 6 can be manually rotated to complete detection at multiple detection points. In addition to the embodiment, a driving device can also be transmissionally connected to the support roller 4. The driving device is a servo motor for driving the support roller 4 to rotate, thereby driving the measured sub 6 to rotate on the support roller 4 to complete detection at multiple detection points.

[0059] If the axial size deviation of the inner and outer rings of the measured sub 6 meets the requirements, the next winding operation can be continued on the tool.

[0060] In order to detect the height size of the wire package after winding, a height gauge 3 is also slidably installed on the detection rail 714, and a third detection scale 718 is provided in the movement range of the free end of the detection rail 714 corresponding to the height gauge 3. The 0 point scale of the third detection scale 718 is located at the end of the free end of the detection rail 714.

[0061] When the winding operation is performed, the height gauge 3 is slid to the end of the detection rail 714 close to the transverse sliding block 708, and after the winding is completed, the height gauge 3 is pushed back to make one end surface of the height gauge 3 contact the wire package, at this time, the scale value indicated by the contact surface between the height gauge 3 and the wire package is the height dimension of the wire package.

[0062] Thus, the three processes of the stator dimension detection, the winding and the wire package height detection can be simultaneously completed by using one set of tooling, the work of workers in carrying between different toolings is avoided, the labor intensity of the workers can be reduced, the work efficiency is improved, meanwhile, the unified positioning standard is adopted in the three processes, which is favorable for reducing the production measurement error and improving the product quality.

[0063] For those skilled in the art, according to the teaching of the present application, the changes, modifications, replacements and variations made to the embodiments without departing from the principles and spirits of the present application still fall into the protection scope of the present application.
