[0029] Embodiment 1:

[0030] See also Figure 1-4 The utility model describes the above technical solution in detail through the following embodiments:

[0031] A wire pressing device for a winding machine for processing aluminum enameled wire, comprising:

[0032] The winding machine 1 comprises a workbench 11 , a driving device is arranged on the front side of the top face of the workbench 11 , the driving device is connected to a winding frame 17 , and the driving device is used to drive the winding frame 17 to rotate.

[0033] The winding frame 17 adopts a well-known I-shaped wheel winding drum, and the winding frame 17 is driven by a driving device to achieve the winding of the aluminum enameled wire.

[0034] The driving device includes a winding motor 12 , the output shaft of the winding motor 12 is connected to a fixed ejector 13 , the fixed ejector 13 is clamped with a winding frame 17 , the other end of the winding frame 17 is clamped with a movable ejector 14 , and the movable ejector 14 is connected to a winding cylinder 16 .

[0035] The winding motor 12 can be a servo motor or a stepper motor, and the winding motor 12 is fixedly installed on the right side of the top surface of the workbench 11 by bolts. The output shaft of the winding motor 12 is clamped with the fixed ejector pin 13. After the winding motor 12 is started, the fixed ejector pin 13 can be driven to rotate by the output shaft.

[0036] The winding cylinder 16 is fixedly mounted on the left side of the top surface of the workbench 11 through the mobile frame 15, and the piston rod of the winding cylinder 16 is rotatably connected to the movable ejector pin 14. By controlling the extension or retraction of the piston rod of the winding cylinder 16, the distance between the movable ejector pin 14 and the fixed ejector pin 13 can be changed to achieve the clamping or release of the winding frame 17.

[0037] When the winding motor 12 drives the fixed ejector pin 13 to rotate, the winding frame 17 and the movable ejector pin 14 can be driven to rotate.

[0038] The wire crimping assembly 2 includes two wire crimping wheels 21, which are in contact with the upper and lower sides of the middle of the winding frame 17. The two wire crimping wheels 21 are connected to a wire crimping spring 27 through a synchronization device. The two wire crimping wheels 21 can move in opposite directions at the same time through the synchronization device. The wire crimping spring 27 is used to provide pressure for the wire crimping wheel 21 in the direction of the winding frame 17.

[0039] The center of the crimping wheel 21 is a metal shaft, and the outside of the metal shaft is wrapped with elastic materials such as rubber. The surface of the crimping wheel 21 contacts the middle of the winding frame 17.

[0040] The synchronizing device comprises a connecting rod 23 , and a plug-in shaft 22 is rotatably mounted on the head of the connecting rod 23 , and the plug-in shaft 22 is inserted from the left and right ends of the crimping wheel 21 .

[0041] The crimping wheel 21 is plugged into the plug-in shaft 22 , and the crimping wheel 21 can rotate between the connecting rods 23 on the left and right sides through the plug-in shaft 22 .

[0042] A clamping shaft 24 is provided in the middle of the connecting rod 23 , and a synchronous gear 25 is clamped on the clamping shaft 24 , and two synchronous gears 25 on the same side are meshed.

[0043] When one of the crimping wheels 21 moves upward or downward, the connecting rod 23 can drive the synchronous gear 25 connected to the connecting rod 23 to move in the same direction, thereby driving the other synchronous gear 25 to move in the opposite direction, and then driving the other crimping wheel 21 to move in the opposite direction through another connecting rod 23, and at the same time, the movement amplitudes of the two crimping wheels 21 are the same.

[0044] A pressing plate 26 is provided at the tail of the connecting rod 23 , and a wire pressing spring 27 is mounted between two pressing plates 26 on the same side, and two end surfaces of the wire pressing spring 27 are respectively against the two pressing plates 26 .

[0045] The elastic force of the wire pressing spring 27 can simultaneously drive the upper and lower pressing plates 26 away from each other, thereby driving the wire pressing wheel 21 to approach each other through the connecting rod 23. When the aluminum enameled wire on the winding frame 17 begins to be wound, the coil thickness increases, which drives the wire pressing wheels 21 to move away from each other. At this time, the pressing plates 26 approach each other, thereby compressing the wire pressing spring 27 to ensure the pressure of the wire pressing wheel 21 on the aluminum enameled wire.

[0046] The adjusting assembly 3 includes an adjusting frame 31 and a fixing frame 32. The synchronizing device is connected to the adjusting frame 31 and the fixing frame 32. The adjusting frame 31 is connected to a moving device. The moving device is used to drive the adjusting frame 31 to move, thereby driving the synchronizing device to move, and then changing the distance between the adjusting frame 31 and the fixing frame 32 to achieve clamping of crimping wheels 21 of different sizes. The adjusting frame 31 and the fixing frame 32 are rotatably connected to the clamping shaft 24.

[0047] Driving the adjustment frame 31 to move can drive the connecting rod 23 to move through the clamping shaft 24, thereby changing the distance between the connecting rods 23 on the left and right sides, thereby changing the length of the crimping wheel 21 that can be clamped by the connecting rods 23 on the left and right sides, and thus adapting to winding frames 17 of different sizes.

[0048] The moving device includes an adjusting screw 34 , and the adjusting screw 34 is threadedly connected with a slider 33 , and the slider 33 is fixedly installed at the bottom of the adjusting frame 31 by bolts.

[0049] Since the adjusting screw 34 is threadedly connected to the slider 33 , when the adjusting screw 34 rotates, the slider 33 can be driven to move along the axis direction of the adjusting screw 34 , thereby driving the adjusting frame 31 to move.

[0050] The end of the adjusting screw 34 is connected to a hand wheel 36 via a worm gear transmission device 35 .

[0051] The worm gear transmission device 35 adopts a known worm gear and worm gear transmission device with self-locking capability, the hand wheel 36 is clamped with the worm gear, and the adjusting screw 34 is clamped with the worm gear. By rotating the hand wheel 36, the worm gear can be driven to rotate through the worm, and the adjusting screw 34 can be driven to rotate through the worm gear. However, the adjusting screw 34 cannot drive the hand wheel 36 to rotate through the worm gear transmission device 35.

[0052] When using the device in this embodiment, the operator selects a corresponding wire pressing wheel 21 according to the size of the winding frame 17 on which the wire needs to be wound.

[0053] The hand wheel 36 is rotated to drive the adjusting screw 34 to rotate through the worm gear 35, and the slider 33 is driven to move along the axis of the adjusting screw 34, thereby driving the adjusting frame 31 to move, thereby changing the distance between the adjusting frame 31 and the fixing frame 32. Until the distance between the adjusting frame 31 and the fixing frame 32 is greater than the length of the selected crimping wheel 21.

[0054] One end of the crimping wheel 21 is plugged into the plug-in shaft 22 on the fixing frame 32 , and then the hand wheel 36 is rotated to drive the adjusting frame 31 to move toward the fixing frame 32 , so as to fix the crimping wheel 21 .

[0055] At this time, under the elastic force of the wire pressing spring 27, the wire pressing wheels 21 approach each other.

[0056] By controlling the piston rod of the winding cylinder 16 to retract, the distance between the movable ejector pin 14 and the fixed ejector pin 13 can be increased, one end of the winding frame 17 is clamped with the fixed ejector pin 13, and then the piston rod of the winding cylinder 16 is controlled to extend, thereby driving the movable ejector pin 14 to support the other end of the winding frame 17.

[0057] At this time, the wire pressing wheel 21 contacts the upper and lower sides of the middle of the winding frame 17. The head of the aluminum enameled wire is fixed to the winding frame 17, and the winding motor 12 is started to drive the fixed ejector 13 to rotate, thereby driving the winding frame 17 to rotate to achieve winding. During the winding, the wire pressing wheel 21 is always in contact with the aluminum enameled wire.

[0058] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
