Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 to 2, it is the structural schematic diagram of the core-pulling height adjusting mechanism of the air-core coil winding spindle provided by the present invention. The core-pulling height adjusting mechanism of the air-core coil winding spindle comprises a rotating base 10, a core-pulling assembly 20 inserted in the rotating base 10, and an adjusting assembly 30 arranged between the rotating base 10 and the core-pulling assembly 20. It is conceivable that the core height adjustment mechanism of the air coil winding spindle further includes other functional modules, such as an assembly component, a mounting component, a guiding component, and the like, which are well known to those skilled in the art and will not be described in detail herein.
The rotary base 10 may be disposed on a machine (not shown) through a rotating assembly (not shown), and a portion such as a driving gear (not shown) may be disposed on an outer sidewall of the rotary base 10, and then the rotary base 10 may be driven to rotate by a driving mechanism such as a motor, so as to perform winding, i.e., winding a wire into an air-core coil. The above-mentioned specific structure and operation principle should be prior art, and are not described herein again. The rotary base 10 includes a central stepped hole 11, and a groove-shaped hole 12 penetrating the central stepped hole 11. The central stepped hole 11 is a through hole passing through the central axis of the rotary base 10 and has a stepped portion 13. The stepped portion 13 is used to abut against one end of a pressing elastic member described below, and will be described below together with the pressing elastic member. The slot-shaped hole 12 is used for inserting a plug pin, which will be described below together with the plug pin.
The core pulling assembly 20 comprises a connecting rod 21 inserted in the central stepped hole 11, a wire blocking cylinder 22 fixedly arranged on the connecting rod 21, a pull rod 23 connected with the connecting rod 21, a pressing elastic piece 24 arranged between the connecting rod 21 and the central stepped hole 11, a plug pin 25 inserted between the connecting rod 21 and the pull rod 23, and an index assembly 26 fixedly arranged at the tail end of the pull rod 23. The connecting rod 21 is connected between the wire blocking cylinder 22 and the pull rod 23, and is inserted in the central stepped hole 11. The thread take-up drum 22 is intended per se to be of the prior art and is inserted in a lower mould (not shown). The thread blocking cylinder 22 extends out of the lower mold during winding and the thread blocking cylinder 22 is submerged into the lower mold during blanking, so that the detailed structure thereof will not be described in detail. The pull rod 23 is disposed at the other end of the connecting rod 22 opposite to the wire blocking cylinder 22. The rod 23 is connected to the rod 21 by the plug 25, so that the rod 21 has an insertion hole 211 on a side facing the rod 23. The pull rod 23 is inserted into the insertion hole 211. The free end of the pull rod 23 extends out of the rotary base 10 to set the index assembly 26. Meanwhile, the connecting rod 21 and the pull rod 23 are correspondingly provided with a through hole for inserting the bolt 25, which is not described herein again. Since the pull rod 23 is inserted into the insertion hole 211 of the connecting rod 21, a step is formed at the boundary between the connecting rod 21 and the pull rod 23. The pressing elastic member 24 is interposed between the step and the step portion 13 of the central step hole 11, and may be a spring. Under the action of the pressing elastic piece 24 and when the pull rod 23 is not subjected to external force, the thread blocking cylinder 22 extends out of the lower die. The plug 25 is inserted in the pull rod 23 and the connecting rod 21 along an axial direction perpendicular to the rotary base 10, and both ends of the plug are inserted in the slot-shaped holes 12. Since the connecting rod 21 and the pull rod 23 need to reciprocate in the axial direction of the rotary base 10, the length of the slot-shaped hole 12 in the axial direction of the central stepped hole is greater than the diameter of the plug 25. The pulling assembly 26 includes a pulling ring 261 fixedly disposed at one end of the pulling rod 23, and a pushing cylinder 262 fixedly disposed on the pulling rod 23 and located between the pulling ring 261 and an adjusting cylinder described below. The pull ring 261 may be composed of a plurality of parts, such as an end screw, a snap spring, a nut, and the like, and is fixedly disposed at a free end of the pull rod 23, so as to facilitate connection with a core-pulling driving mechanism (not shown), and achieve the purpose of core-pulling under the driving of the core-pulling driving mechanism. The ejection cylinder 262 is fixed on the pull rod 23 by a pin, so as to form a step with the pull ring 261, thereby facilitating the clamping connection with the core-pulling driving mechanism and avoiding the contact with the adjusting component 30.
The adjusting assembly 30 includes an adjusting cylinder 31 screwed to the rotary base 10, and a bushing 32 disposed between the pull rod 23 and the rotary base 10. The adjusting cylinder 31 includes a first through hole 311 screwed to one end of the rotary base 10, and a second through hole 312 sleeved on the pull rod 23. The first through hole 311 is provided with a thread to be in threaded connection with one end of the rotary base 10. It is conceivable that the specification of the thread on the first through hole 311 can be designed according to actual requirements, so as to control the height of the wire blocking cylinder 22 extending out of the lower die during the process of rotating the adjusting cylinder 31. The diameter of the second through hole 312 is smaller than that of the first through hole 311, so as to form a butting surface. The abutting surface abuts against one end of the abutting cylinder 262 of the traction assembly 26, that is, the free end of the second through hole 312 abuts against the traction assembly 26, so that the pull rod 23 is driven to reciprocate in the rotation process of the adjusting cylinder 31, and the purpose of core pulling is achieved. The shaft sleeve 32 is used for sliding the pull rod 23 and the rotary base 10 to each other. When the adjusting cylinder 31 is rotated to move the second through hole 312 in a direction away from or close to the rotary base 10, the connecting rod 21 is moved in a direction away from or close to the rotary base 10 under the action of the pressing elastic element 24, so as to adjust the height of the wire blocking cylinder 22 extending out of the lower die.
Compared with the prior art, the utility model provides a high adjustment mechanism of loosing core of air core coil wire winding main shaft passes through set up between one side of roating seat 10 and the connecting rod 21 and compress tightly elastic component 24, and set up adjusting part 30 between the end of roating seat 10 and the pull rod 23. When the relative positions of the pull rod 23 and the connecting rod 21 with the rotary base 10 need to be adjusted, the adjusting cylinder 31 of the adjusting assembly 30 is rotated, because the adjusting cylinder 31 is in threaded connection with the rotary base 10, and one end of the adjusting cylinder 31 abuts against the index assembly 26 fixed on the pull rod 23, so that the pull rod 23 can be pulled by rotating the adjusting cylinder 31, and meanwhile, the position relationship between the core pulling assembly 20 and the rotary base 10 is kept stable due to the existence of the compression elastic piece 24, and the core pulling assembly does not shake. In addition, by designing the specifications of the threads on the adjusting cylinder 31 and the rotary seat 10, the moving amount of the connecting rod 21 and the pull rod 23 can be adjusted, so that the extending amount of the wire blocking cylinder 22 connected with the connecting rod 21 can be adjusted, and the relationship between the extending amount of the wire blocking cylinder 22 and the axial size of the wound wire can be adjusted, so that the wire is prevented from being taken out when the die is opened due to the fact that the wire is tightly attached to the upper die, and the coil is poor.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
