Description

Technical Field

[0001] The invention relates to the technical field of motor stators, and in particular to a detection mechanism for stator bent lead wires. Background Art

[0002] like Figure 1 As shown, the motor stator includes a stator core 1 and a winding 2. The inner circumference of the stator core 1 is provided with a wire embedding groove, and the winding 2 cooperates with the wire embedding groove. The winding 2 is generally provided with a lead wire 3 for connecting to a power source. The lead wire usually needs to be bent so that it has a curved section 3a and a straight section 3b. In addition, a groove 4 is provided on the inner circumference of the stator core 1.

[0003] The stator lead wire bending is an important process in the stator process. After the lead wire is bent, its position and straightness will change. The bending of the lead wire directly affects whether the customer can install it. Therefore, it is necessary to detect the position of the bent lead wire to ensure that the customer can install it smoothly after receiving the stator. Lead wire position detection is an important measurement method after the lead wire is bent. The existing method of checking the lead wire position can only be measured using a projector or three-coordinate measurement. Although this method can accurately measure the position of the lead wire, it requires special equipment and measurement personnel with relevant measurement knowledge to perform detection. General operators cannot detect it alone. Summary of the invention

[0004] The invention provides a detection mechanism for stator bent lead wires. The detection mechanism can save a lot of time in confirming the position of the stator lead wires.

[0005] A detection mechanism for stator bent lead wires, comprising: Base; A support for supporting the stator, the support being fixed on the base; A detection plate, wherein the detection plate is provided with a plurality of through holes for cooperating with a plurality of lead wires on the stator; The guide assembly, the detection plate cooperates with the guide assembly; A lifting drive mechanism drives the detection plate to lift to detect whether each lead wire can pass through the corresponding through hole, and the lifting drive mechanism is connected to the detection plate.

[0006] Furthermore, it also includes a positioning component for plugging and matching with the grooves on the stator core, and the positioning component is arranged on the support.

[0007] Furthermore, the positioning assembly comprises a positioning block, which is fixed to the support and is provided with positioning teeth for plugging and cooperating with the groove.

[0008] Furthermore, the support is an annular component, and a limiting step for cooperating with the stator core is provided on the inner wall of the support.

[0009] Furthermore, the guide assembly includes a fixed seat, a guide shaft, and a sliding sleeve. The fixed seat is fixed to the base, one end of the guide shaft is fixed to the fixed seat, and the other end of the guide shaft passes through the sliding sleeve and slidably cooperates with the sliding sleeve. The detection plate is provided with an assembly hole that passes through the detection plate, the sliding sleeve cooperates with the assembly hole, and the sliding sleeve is fixed to the detection plate.

[0010] Furthermore, the guide assembly also includes a spring, which is sleeved on the guide shaft, one end of the spring abuts against the fixing seat, and the other end of the spring abuts against the sliding sleeve or the detection plate.

[0011] Furthermore, the lifting drive mechanism includes a pressure rod, a connecting rod, and a wheel-shaped component. The pressure rod is hinged to the base, a strip hole is provided on the pressure rod, the connecting rod is fixed to the detection plate, the wheel-shaped component is rotatably mounted on the connecting rod, and the wheel-shaped component and the strip hole are clearance-matched. When the pressure rod rotates, the force generated by the pressure rod causes the wheel-shaped component to move along the strip hole on the pressure rod, and at the same time the pressure rod drives the wheel-shaped component to rise or fall, and the wheel-shaped component drives the connecting rod to rise or fall.

[0012] When assembling the stator and the support, the positioning teeth are plugged into the grooves to make the lead wires on the stator located at the specified position. The operator applies a counterclockwise rotation to the pressure rod through the handle. When the pressure rod rotates in the reverse direction, the force generated by the pressure rod causes the wheel-shaped component to move along the strip hole on the pressure rod. At the same time, the pressure rod drives the wheel-shaped component to descend, and the wheel-shaped component drives the connecting rod to descend, and the connecting rod drives the detection plate to descend. During the descent of the detection plate, observe whether the lead wires on the stator can pass through the corresponding through holes. If each through hole on the detection plate can allow the corresponding lead wire to pass through, the bending type of each lead wire is qualified. If one of the lead wires cannot pass through its corresponding through hole, the bent lead wire is unqualified.

[0013] The inspection fixture of the present invention combines a positioning seat and a measuring mechanism together to detect the stator lead-out position. After the stator is installed on the support, it is only necessary to drive the inspection plate down through the pressure rod to detect whether the bending of the lead-out wire is qualified. The operation is fast and simple, so the confirmation of the stator lead-out line position can save a lot of time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the examples of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other implementation methods can be obtained according to the drawings in the specification without paying creative work, and these implementation methods are still within the protection scope of the claims of the present invention.

[0022] like Figures 1 to 5 A detection mechanism for stator bent lead wires of the present invention includes a base 11, a support 12, a detection plate 13, a guide assembly, and a lifting drive mechanism. The following describes each part and the relationship between them in detail.

[0023] The base 11 is a rectangular or cubic plate-shaped component, and a plurality of threaded holes are provided on the base 11. Screws are respectively passed through the support 12 and the guide assembly to connect with the threaded holes, so that the support 12 and the guide assembly are fixed to the base 11 as a whole.

[0024] The support 12 is used to support the stator, and the support 12 is fixed on the base 11; the support 12 is preferably fixed to the base 11 by screws. In this embodiment, the support 12 is an annular component, and a limiting step 12a for cooperating with the stator core 1 is provided on the inner wall of the support 12. A groove 12b is provided on the support 12, and the groove 12b is located above the limiting step 12a. The groove 12b passes through the inner wall and the axial end face of the support 12, that is, there are notches on the axial end face and the inner wall of the support 12.

[0025] It also includes a positioning assembly for plugging and matching with the groove 4 on the stator core 1, and the positioning assembly is arranged on the support 12. The positioning assembly includes a positioning block 14, which is fixed to the support 12, and is provided with a positioning tooth 14a for plugging and matching with the groove 4. When the stator and the support 12 are assembled, the positioning tooth 14a is plugged and matched with the groove 4, so that the lead wire 3 on the stator can be located at a specified position, so that the detection plate 13 can detect the lead wire 3 when the detection plate 13 is lowered later.

[0026] The detection plate 13 is provided with a plurality of through holes 13a for cooperating with the plurality of lead wires 3 on the stator. When the detection plate 13 is lowered, if each through hole 13a on the detection plate 13 can allow the corresponding lead wire 3 to pass through, then the bending of each lead wire 3 is qualified. If one of the lead wires 3 cannot pass through its corresponding through hole 13a, then the bent lead wire 3 is unqualified.

[0027] The detection plate 13 is provided with a notch 13 b, which can reduce the material used for the detection plate 13 and thus reduce the weight and manufacturing cost of the detection plate 13 .

[0028] The detection plate 13 cooperates with the guide assembly, and the guide assembly is used to make the detection plate 13 rise or fall along a straight line. The guide assembly includes a fixed seat 15, a guide shaft 16, and a sliding sleeve 17. The fixed seat 15 is fixed to the base 11, and the fixed seat 15 is fixed to the base 11 by screws. The fixed seat 15 has a plug hole, one end of the guide shaft 16 is fixed to the fixed seat 15, and one end of the guide shaft 16 is inserted into the plug hole on the fixed seat 15 and has an interference fit with the plug hole, so that the guide shaft 16 is fixed to the fixed seat 15. The other end of the guide shaft 16 passes through the sliding sleeve 17 and slides with the sliding sleeve 17. The detection plate 13 is provided with an assembly hole that passes through the detection plate 13, and the sliding sleeve 17 cooperates with the assembly hole, and the sliding sleeve 17 is fixed to the detection plate 13.

[0029] The guide assembly further includes a spring 18, which is sleeved on the guide shaft 16, one end of the spring 18 abuts against the fixing seat 15, and the other end of the spring 18 abuts against the sliding sleeve 17 or the detection plate 13. The guide assembly is further provided with a limit block 22, which is fixed to the guide shaft 16 and is used to limit the highest position of the sliding sleeve 17 when it rises.

[0030] The lifting drive mechanism drives the detection plate 13 to lift and lower to detect whether each lead wire 3 can pass through the corresponding through hole 13a, and the lifting drive mechanism is connected to the detection plate 13. The lifting drive mechanism includes a pressure rod 19, a connecting rod 20, and a wheel-shaped component 21. One end of the pressure rod 19 is hinged to the base 11, and the other end of the pressure rod 19 is connected to a handle 23. The pressure rod 19 is provided with a strip hole 19a. The connecting rod 20 is fixed to the detection plate 13, and the wheel-shaped component 21 is rotatably mounted on the connecting rod 20. The wheel-shaped component 21 and the strip hole 19a are clearance-matched. The wheel-shaped component 21 is composed of a bearing and a shaft. One end of the shaft is fixed to the connecting rod 20, and the other end of the shaft is fixed to the bearing. When the bearing is subjected to force, the bearing can rotate relative to the shaft.

[0031] The use process of the present invention is as follows: When assembling the stator and the support 12, the positioning teeth 14a are inserted into the grooves 4 to make the lead wires 3 on the stator located at the specified position. The operator applies a counterclockwise ( Figure 3 ) rotation, when the pressure rod 19 rotates in the reverse direction, the force generated by the pressure rod 19 causes the wheel-shaped component 21 to move along the strip hole 19a on the pressure rod 19 (the bearing in the wheel-shaped component 21 rotates at the same time), and at the same time, the pressure rod 19 drives the wheel-shaped component 21 to descend, and the wheel-shaped component 21 drives the connecting rod 20 to descend, and the connecting rod 20 drives the detection plate 13 to descend. During the descent of the detection plate 13, observe whether the lead wires 3 on the stator can pass through the corresponding through holes 13a. If each through hole 13a on the detection plate 13 allows the corresponding lead wire 3 to pass through, then the bending type of each lead wire 3 is qualified. If one of the lead wires 3 cannot pass through its corresponding through hole 13a, then the bent lead wire 3 is unqualified. During the descent of the detection plate 13, the sliding sleeve 17 fixed to the detection plate 13 applies pressure to the spring 18 to compress the spring 18. When the operator releases the handle 23, the elastic properties accumulated in the spring 18 are released, and the spring 18 pushes the sleeve 17 and the detection plate 13 upward, so that the detection plate 13 is separated from the lead wire 3, thereby completing the detection, and the operator can take away the stator.
