Description

Technical fields:

[0001] This utility model relates to the field of motor processing and manufacturing technology, and more specifically to a rotary feeding device for a stator winding expansion and shaping mechanism. Background technology:

[0002] In the existing motor stator manufacturing process, the stator winding needs to be installed in the slot formed on the inner side wall of the stator. Then, it needs to be placed in the expansion device. The expansion rod of the expansion device is inserted into the central through hole of the stator. Through expansion, the positioning central insertion hole is opened, and the stator winding installed on it expands outward together, making it more firmly fixed.

[0003] The existing method involves setting up a placement plate below the tension rod and vertically inserting the stator into the mounting hole of the placement plate. Because the tension rod is very close to the placement plate, it is easy for the stator to collide with the tension rod when loading and unloading, which affects the processing effect and easily produces scrap parts. Utility Model Content:

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a rotary feeding device for a stator winding expansion and shaping mechanism. It can move the flipping placement plate forward and flip it when loading and unloading the stator, which facilitates loading and unloading the stator. It is not easy to break the expansion rod, thus ensuring the processing effect and processing quality.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A rotary feeding device for a stator winding expansion and shaping mechanism includes a frame. A rearwardly extending movable slot is formed in the middle of the front wall of the top plate of the frame. The top and bottom ends of the movable slot extend out of the top and bottom surfaces of the top plate of the frame. A U-shaped horizontal movable frame is inserted into the movable slot. The upper part of the outer side wall of the side beams on the left and right sides of the horizontal movable frame is formed with an outwardly extending horizontally extending edge. The bottom surface of the extending edge presses against the top surface of the top plate of the frame on the left and right sides of the movable slot. The outer side wall of the side beam is in close contact with the inner side wall of the left and right sides of the movable slot. A push cylinder is fixed in the middle rear part of the top surface of the top plate of the frame. A connecting block is fixed at the end of the push rod of the push cylinder. The connecting block is fixed on the top surface of the rear beam of the horizontal movable frame.

[0007] The flip-and-place plate is located in the horizontal moving frame, and the connecting shafts fixed in the middle of its left and right side walls are movably connected to the left and right side beams of the horizontal moving frame through bearings.

[0008] The top surface of the flip-up placement plate from the front to the middle is formed with a downwardly extending circular mounting hole, and a central insertion hole is formed in the middle of the bottom surface of the circular mounting hole.

[0009] Side limiting baffles are fixed to the bottom surface of the top plate of the frame at the middle of the left and right sides of the movable slot. The top surface of the side limiting baffle at the end near the middle of the movable slot is in close contact with the bottom surface of the flip-up placement plate.

[0010] A middle blocking block is fixed to the top surface of the middle part of the side beam on the right side of the horizontal moving frame. The left side wall of the middle blocking block is formed with a blocking part extending to the left. The bottom surface of the blocking part is close to the top surface of the flip-up placement plate, and the rear wall surface of the blocking part corresponds to the top surface of the middle part on the right side of the flip-up placement plate.

[0011] The outstanding effect of this utility model is:

[0018] For example, see below. Figures 1 to 5 As shown, a rotary feeding device for a stator winding expansion and shaping mechanism includes a frame 10, which is fixed below the expansion rod of the expansion and shaping machine. A rearwardly extending movable slot 11 is formed in the middle of the front wall of the top plate of the frame 10. The top and bottom ends of the movable slot 11 extend beyond the top and bottom surfaces of the top plate of the frame 10. A U-shaped horizontal movable frame 20 is inserted into the movable slot 11. The outer walls of the side beams 21 on the left and right sides of the horizontal movable frame 20... The upper part is formed with an outward horizontally extending edge 22. The bottom surface of the extension edge 22 presses against the top surface of the top plate of the frame 10 on the left and right sides of the movable slot 11. The outer side wall of the side beam 21 is close to the inner side wall of the left and right sides of the movable slot 11. A push cylinder 12 is fixed in the middle rear part of the top surface of the top plate of the frame 10. A connecting block 13 is fixed at the end of the push rod of the push cylinder 12. The connecting block 13 is fixed on the top surface of the rear beam of the horizontal movable frame 20.

[0019] The top surface of the top plate of the frame 10 on both the left and right sides of the movable slot 11 is formed with a front-to-back extending edge protrusion 14. The top surface of the edge protrusion 14 is fixed with a front-to-back extending limiting plate 15. The top surface of the extending edge 22 is close to the bottom surface of the inner side of the limiting plate 15, and the outer side wall of the extending edge 22 is close to the inner side wall of the corresponding edge protrusion 14.

[0020] The flip-and-place plate 30 is located in the horizontal moving frame 20, and the connecting shafts fixed in the middle of its left and right side walls are movably connected to the left and right side beams 21 of the horizontal moving frame 20 through bearings.

[0021] The top surface of the flip-up placement plate 30 from the front to the middle is formed with a downwardly extending circular mounting hole 31, and the bottom surface of the circular mounting hole 31 is formed with a central insertion hole 32.

[0022] Side limiting baffles 1 are fixed to the bottom surface of the top plate of the frame 10 at the middle of the left and right sides of the movable slot 11. The top surface of the side limiting baffle 1 at the end near the middle of the movable slot 11 is in close contact with the bottom surface of the flip-up placement plate 30.

[0023] Furthermore, a middle blocking block 40 is fixed to the top surface of the middle part of the side beam 21 on the right side of the horizontal moving frame 20. The left side wall of the middle blocking block 40 is formed with a blocking part 41 extending to the left. The bottom surface of the blocking part 41 is in close contact with the top surface of the flip-up placement plate 30, and the rear wall surface of the blocking part 41 corresponds to the top surface of the middle part on the right side of the flip-up placement plate 30.

[0024] Furthermore, an annular positioning sleeve 33 is inserted into the circular mounting hole 31. The outer wall of the annular positioning sleeve 33 is close to or near the inner wall of the circular mounting hole 31. An edge positioning slot 34 is formed on the upper part of the outer wall of the annular positioning sleeve 33. The top surface of the edge positioning slot 34 extends outward from the top surface of the annular positioning sleeve 33. An outwardly extending horizontally outer slot 311 is formed on the upper inner wall of the circular mounting hole 31 corresponding to the edge positioning slot 34. The top surface of the outer slot 311 extends outward from the top of the flip-up placement plate 30. The positioning block 2 is inserted into the corresponding outer slot 311 and the side positioning slot 34. The two side walls of the positioning block 2 are in close contact with the corresponding inner side walls of the corresponding outer slot 311 and the side positioning slot 34. The center of the positioning block 2 is formed with a waist-shaped through hole. The screw part of the fixing bolt 3 is inserted into the corresponding waist-shaped through hole and screwed into the screw hole formed on the bottom surface of the corresponding outer slot 311. The bottom surface of the rotating part of the fixing bolt 3 presses against the top surface of the positioning block 2, and the bottom surface of the positioning block 2 presses against the bottom surface of the outer slot 311.

[0025] Furthermore, the inner diameter of the central through hole of the annular positioning sleeve 33 is larger than the inner diameter of the central insertion hole 32.

[0026] Furthermore, vertical limiting posts 4 are screwed onto the top surfaces of the left and right sides of the front part of the annular positioning sleeve 33. When the flip-up placement plate 30 is flipped into a vertical position, the vertical limiting posts 4 extend laterally to support the lower side wall of the stator.

[0027] Furthermore, a connecting block is fixed to the front of the left limiting plate 15, and a proximity switch 5 is fixed on the connecting block. The sensing end of the proximity switch 5 extends out of the left side wall of the connecting block and corresponds to the right side wall of the middle blocking block 40.

[0028] In this embodiment, the hydraulic cylinder 12 is connected to the solenoid control valve of the hydraulic system via a connecting pipe. The hydraulic system consists of components such as an oil pump, solenoid control valve, and oil tank, which are connected by a connecting pipe. All electrical components used in this embodiment are electrically connected to the control host via electrical connection lines and are controlled by the control host. This is a conventional structure and will not be described in detail here.

[0029] In this embodiment, the horizontal moving frame 20 is moved forward by pushing the push rod of the hydraulic cylinder 12. During the movement, the annular positioning sleeve 33 installed at the flipping placement plate 30 is biased forward, with its front end being heavier than its rear end. As the flipping placement plate 30 moves, it flips forward until the top surface of the middle part of the right side of the flipping placement plate 30 is in front and presses against the rear wall of the corresponding blocking part 41. At the same time, the front wall of the side limiting baffle 1 near the middle part of the moving slot 11 presses against the bottom surface of the flipping placement plate 30 (which becomes the rear wall after flipping), thus positioning the flipping placement plate 30. Then, the stator can be manually inserted horizontally into the annular positioning sleeve 33, so that the edge of its rear end presses against the bottom surface of the circular mounting hole 31 around the central insertion hole 32, thus achieving positioning. At this time, the sensing end of the proximity switch 5 approaches and senses the protrusion formed in the middle of the right side wall of the middle blocking block 40, indicating that it has moved into place.

[0030] Then, by pressing the control switch of the control host, the electromagnetic control valve of the corresponding hydraulic system is activated, causing the push rod of the push cylinder 12 to retract, causing the horizontal moving frame 20 to move backward. At this time, the lower part of the flipping placement plate 30 is blocked by the side limit baffle 1 at the rear, causing it to flip backward until it is horizontal and located between the top surface of the side limit baffle 1 and the bottom surface of the blocking part 41, thus achieving the limit.

[0031] Until the push rod of the hydraulic cylinder 12 retracts to its last end, the rear wall of the horizontal moving frame 20 presses against the rear wall of the moving slot 11 to achieve a limit. At this time, the center of the stator is exactly aligned with the expansion rod. The expansion rod only needs to descend and extend into the center of the stator to expand and complete the processing. This structure and the expansion rod device are conventional structures and will not be described in detail here.

[0032] After processing is completed in this embodiment, the flipping plate 30 can be pushed out and flipped by pushing the push rod of the hydraulic cylinder 12. Then, the stator can be manually removed horizontally, which is very convenient and has a good effect.

[0033] In this embodiment, the annular positioning sleeve 33, being a component in direct contact with the stator, is prone to wear on its inner wall over time, requiring periodic replacement and maintenance. Because it is fixed by the positioning block 2, the annular positioning sleeve 33 can be easily removed and replaced by loosening the corresponding fixing bolts 3 and moving the positioning block 2 outwards so that it is no longer in the corresponding edge positioning slot 34. This is very convenient.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
