Description

Technical Field

[0001] The utility model relates to a quick paper inserting mechanism for motor stator insulation paper, belonging to the technical field of motor manufacturing equipment. Background Art

[0002] During the motor production process, insulating paper needs to be inserted into the motor stator core slots to insulate the slots. The insulating paper is a long rectangular strip with a "U"-shaped cross-section. Inserting the motor stator insulating paper is an important step in motor manufacturing.

[0003] Traditional methods of inserting insulating paper mostly rely on manual operation, where shorter insulating papers are manually bent into a "U" shape and then inserted one by one into the stator core slots of the motor. This method has the problems of large manual labor and low paper insertion efficiency. On the other hand, manual insertion of insulating paper is prone to problems such as insulating paper wrinkles and position deviations, which affect the performance and quality of the motor. Therefore, it is necessary to improve it. Summary of the Invention

[0004] The purpose of the utility model is to provide a motor stator insulation paper fast insertion mechanism to solve the problems of low insertion efficiency and unstable quality of motor stator insulation paper in the prior art, to achieve fast and accurate insertion of insulation paper, and to improve the production efficiency of the motor.

[0005] The technical solution of the utility model is:

[0006] A mechanism for quickly inserting insulating paper into a motor stator comprises a mounting frame, a drive motor, a linkage member and a slide plate, and is characterized in that a forming plate is fixedly mounted on the top of the mounting frame, a forming assembly is mounted on one end of the forming plate, a rotary drive assembly is mounted on the other end of the forming plate, a rotating disk is mounted on the rotary drive assembly, a slide plate is slidably mounted on the mounting frame below the forming plate via a slide rail, a push rod is fixedly mounted on the slide plate via a top seat, an assembly recess is provided on the mounting frame below the slide rail, a drive motor is fixedly mounted in the assembly recess, and a transmission shaft of the drive motor is connected to the slide plate via a linkage member.

[0007] The forming plate is a rectangular plate, with a forming groove in the middle of one end of the forming plate. The cross section of the forming groove is semi-circular, the upper and lower ends of the forming groove are tapered, and the left and right sides of the forming groove are symmetrically provided with recessed slots.

[0008] The profiling assembly includes an assembly block, a profiling cylinder and a profiling block. The assembly block is a rectangular block. A paper feed slot is provided on one end of the assembly block. A profiling cylinder is installed on the other end of the assembly block. The profiling block is fixedly installed on the piston rod of the profiling cylinder. A travel channel is provided on the assembly block between the profiling block and the paper feed slot.

[0009] The rotary drive assembly includes a rotary motor, a driving shaft and a driven shaft. The rotary motor is fixedly mounted on the forming plate. A mounting groove is provided in the forming plate corresponding to the rotary motor. The interface of the mounting groove is "L"-shaped. The driving shaft is movably mounted in the mounting groove through a bearing seat. The driven shaft is movably mounted in the mounting groove on one side of the driving shaft through a bearing seat. One end of the driving shaft is connected to the transmission shaft of the rotary motor, and the other end of the driving shaft is connected to the driven shaft through an active bevel gear and a driven bevel gear.

[0014] The beneficial effects of the present invention compared with the prior art are:

[0015] The motor stator insulation paper quick insertion mechanism inserts the insulation paper into the paper feed slot, and uses the press block and the forming slot to extrude it into a "U" shape. The drive shaft of the driving motor drives the push rod to rotate. When one end of the push rod rotates to the highest position, the push rod and the rotating rod cooperate to push the top seat and the push rod to move upward. The push rod enters the forming slot, and the top of the push rod is inserted into the inner side of the insulation paper. The limiting boss contacts the bottom end of the insulation paper, thereby pushing the insulation paper to move upward along the tapered upper end of the forming slot. In the process of the insulation paper moving upward, it is tightened by the tapered forming slot. The "U"-shaped insulation paper is also gathered, and the curvature of the insulation paper becomes larger. When the "U"-shaped insulation paper is pushed into the wire slot of the motor stator core through the hole, the constraint of the forming slot is lost, and the insulation paper is stretched out under the action of its own elasticity and naturally clamped in the wire slot of the motor stator core, thereby completing the insertion operation of the insulation paper. The motor stator insulation paper fast insertion mechanism effectively solves the problems of low insertion efficiency and unstable quality of motor stator insulation paper in the prior art, realizes fast and accurate insertion of insulation paper, and greatly improves the production efficiency of the motor.

When working, the piston rod of the profiling cylinder 8 pushes the profiling block 9 from the travel channel 11 into the paper feed slot 10, and then enters the forming slot 5 through the paper feed slot 10.

[0025] The other end of the forming plate 4 is equipped with a rotary drive assembly, which includes a rotary motor 12, a driving shaft 13 and a driven shaft 14. The rotary motor 12 is fixedly mounted on the forming plate 4, and a program controller (PLCS6-800) is installed on the rotary motor 12. A mounting groove 15 is provided in the forming plate 4 corresponding to the rotary motor 12. The interface of the mounting groove 15 is "L"-shaped. The driving shaft 13 is movably mounted in the mounting groove 15 through a bearing seat, and the driven shaft 14 is movably mounted in the mounting groove 15 on one side of the driving shaft 13 through a bearing seat. One end of the driving shaft 13 is connected to the transmission shaft of the rotary motor 12, and the other end of the driving shaft 13 is connected to the driven shaft 14 through an active bevel gear 16 and a driven bevel gear 17. A rotating disk 18 is fixedly mounted on one end of the driven shaft 14 of the rotary drive assembly. When working, the rotary motor 12 is controlled by the program controller to drive the rotating disk 18 to rotate intermittently through the cooperation of the active shaft 13 and the driven shaft 14.

[0026] The rotating disk 18 is disc-shaped, and a plurality of limiting bosses 19 are spaced apart on the circumferential edge of the rotating disk 18 . The limiting bosses 19 engage with the circumferential slots 31 of the motor stator core 28 to limit the motor stator core 28 .

[0027] A plurality of clearance holes 20 are evenly spaced in a circular ring shape on the rotating disk 18 inside the limiting boss 19 . The clearance holes 20 are arranged in a one-to-one correspondence with the wire slots 29 of the motor stator core 28 .

[0028] A slide plate 3 is slidably installed on the mounting frame 1 below the forming plate 4 through a slide rail 24, and a top seat 21 is fixedly installed on the slide plate 3. The top seat 21 is a rectangular block, and a top rod 22 is fixedly installed on the top seat 21. The top rod 22 is a long rectangular rod, and a guide protrusion 23 is provided on the end face of the top rod 22 corresponding to the clearance groove 6. The top rod 22 corresponds to the forming groove 5 of the forming plate 4 and is movably plug-in connected. The guide protrusion 23 corresponds to the clearance groove 6 of the forming plate 4 and is movably plug-in connected. When working, the guide protrusion 23 positions the top rod 22, and at the same time, the guide protrusion 23 can have an upward thrust on the insulating paper 30.

[0029] An assembly recess 25 is provided on the mounting frame 1 below the slide rail 24, and a drive motor 2 is fixedly installed in the assembly recess 25. The transmission shaft of the drive motor 2 is connected to the slide plate 3 through a linkage. The linkage includes a rotating rod 26 and a push rod 27. One end of the rotating rod 26 is fixedly mounted on the transmission shaft of the drive motor 2, and the other end of the rotating rod 26 is hinged to the push rod 27.

When working, the transmission shaft of the drive motor 2 rotates continuously, and with the cooperation of the push rod 27 and the rotating rod 26, the slide plate 3 performs reciprocating motion on the slide rail 24.

[0030] When the motor stator insulation paper quick insertion mechanism is working, the insulation paper 30 is first inserted into the paper feed slot 10 of the motor stator insulation paper quick insertion mechanism. After the insertion is completed, the piston rod of the pressing cylinder 8 is started to extend, and the piston rod pushes the pressing block 9 from the travel channel 11 into the paper feed slot 10, thereby pushing the insulation paper 30 in the paper feed slot 10 into the forming slot 5, so that the insulation paper 30 is squeezed into a "U" shape under the cooperation of the pressing block 9 and the forming slot 5, and the control The piston rod of the press cylinder 8 is reset, and the drive motor 2 is started. The transmission shaft of the drive motor 2 drives the push rod 27 to rotate. When one end of the push rod 27 rotates to the highest position, the push rod 27 and the rotating rod 26 cooperate to push the top seat 21 and the push rod 22 to move upward, and the push rod 22 enters the forming groove 5. The top of the push rod 22 entering the forming groove 5 is inserted into the inner side of the insulating paper 30, and the limiting boss 19 contacts the bottom end of the insulating paper 30, thereby pushing the insulating paper 30 along the tapered shape of the forming groove 5. The upper end moves upward. In the process of the insulating paper 30 moving upward, the insulating paper 30 in the shape of a "U" is tightened by the tapered forming groove 5, and the curvature of the insulating paper 30 becomes larger. When the insulating paper 30 in the shape of a "U" is pushed into the wire groove 29 of the motor stator core 28 through the hole, the constraint of the forming groove 5 is lost. The insulating paper 30 is stretched out under the action of its own elasticity and is naturally clamped in the wire groove 29 of the motor stator core 28, thereby completing the insertion operation of the insulating paper 30. As one end of the push rod 27 rotates to the lowest position, the push rod 22 leaves the forming groove 5, and then the next piece of inserted insulating paper 30 is placed in the paper feed slot 10, and the insertion operation of the insulating paper 30 can be started cyclically. The motor stator insulating paper fast insertion mechanism effectively solves the problems of low insertion efficiency and unstable quality of the motor stator insulating paper 30 in the prior art, realizes fast and accurate insertion of the insulating paper 30, and improves the motor production efficiency.
