Description

Technical Field

[0001] This utility model belongs to the field of automation technology, and specifically relates to a winding mechanism with a positioning structure. Background Technology

[0002] Typically, a cylinder has a stator and a rotor. The stator has multiple winding slots, and a coil needs to be wound into each slot.

[0003] Currently, some stator winding equipment still operates by winding a coil into one winding slot on the stator after the equipment has been shut down, and then restarting the equipment to wind a coil into the other winding slot. Others wind coils into different slots sequentially while the equipment is running. The former wastes a considerable amount of time, while the latter saves time, but the overall effect is not ideal, with complex mechanisms, high costs, and low precision. Utility Model Content

[0004] To address the aforementioned problems, the primary objective of this utility model is to provide a winding mechanism with a positioning structure, which solves the technical problem of positioning the stator winding slot during the rotation of the stator rotating rod in current winding mechanisms.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] This utility model provides a winding mechanism with a positioning structure, comprising: a fixed base, a pneumatic device, a first limiting member, a stator rotating rod, and a second limiting member; wherein...

[0007] The fixed base is used to place the pneumatic device, the first limiting member and the second limiting member, and the stator rotating rod is rotatably connected to the fixed base;

[0008] The stator rotating rod is used to place the stator, and a second limiting member is fixedly provided on the stator rotating rod, the second limiting member being disposed opposite to the first limiting member;

[0009] The pneumatic device is connected to the first limiting member and is used to drive the first limiting member to extend and retract; so as to restrict the rotation of the second limiting member by the first limiting member or to allow the second limiting member to rotate by disengaging from the second limiting member.

[0010] This automatic winding mechanism, through the coordinated operation of a fixed base, a pneumatic device, a first limiting member, a stator rotating rod, and a second limiting member, enables stator winding during the operation of the stator winding equipment. Specifically, through the telescopic movement of the pneumatic device, the first and second limiting members engage or disengage, thereby allowing the stator rotating rod to rotate or remain stationary. This achieves stator winding slot positioning during the rotation of the stator rotating rod, reducing manual intervention and improving production efficiency.

[0011] Furthermore, the first limiting member and the second limiting member are connected by a snap-fit mechanism.

[0012] Furthermore, the second limiting member includes:

[0013] The locking ring has a notched annular opening, and fastening grooves are provided at opposite ends of the notch for the fastening rod to pass through and fix the second limiting member to the stator rotating rod.

[0014] The gear ring is integrally connected with the locking ring. The outer surface of the gear ring is provided with spaced protrusions, and a limiting groove is formed between two adjacent protrusions.

[0015] Furthermore, the first limiting member includes a limiting protrusion, which is correspondingly provided with a limiting groove formed on the outer surface of the gear ring to lock or unlock the limiting groove, thereby realizing the rotation or stationary position of the stator rotating rod.

[0016] Furthermore, the pneumatic device includes a telescopic cylinder and a telescopic rod connected to the telescopic cylinder. The telescopic cylinder is used to drive the telescopic rod to perform telescopic movement, and a locking groove is provided at the end of the telescopic rod.

[0017] The first limiting member includes:

[0018] A fixing groove is provided with a receiving space for accommodating the end of the telescopic rod;

[0019] A limiting part is provided at the opening of the fixed groove to embed the snap-fit groove of the telescopic rod, thereby realizing the fixed connection between the first limiting part and the pneumatic device.

[0020] Furthermore, a telescopic track is formed on the fixed base, and the two sides of the first limiting member abut against the side wall of the telescopic track respectively, so as to prevent the first limiting member from moving out of the preset track, which would cause the first limiting member to fail to abut against the second limiting member or fail to abut against the preset position of the second limiting member.

[0021] Furthermore, the stator rotating rod includes a first stator rotating rod and a second stator rotating rod, and the pneumatic device includes a first telescopic rod and a second telescopic rod arranged opposite each other on both sides of a telescopic cylinder. The first stator rotating rod is located on the side closer to the first telescopic rod, and the second stator rotating rod is located on the side closer to the second telescopic rod. Driving the first and second telescopic rods with a single telescopic cylinder saves costs and improves efficiency.

[0022] Furthermore, the stator rotating rod includes a first stator rotating rod, a second stator rotating rod, a third stator rotating rod, and a fourth stator rotating rod, which are respectively arranged around the fixed base;

[0023] The pneumatic device includes a first pneumatic device and a second pneumatic device, which are disposed on opposite sides of the fixed base.

[0024] The first pneumatic device includes a first telescopic cylinder and a first telescopic rod and a second telescopic rod arranged opposite to each other on both sides of the first telescopic cylinder. A first stator rotating rod is arranged on the side closer to the first telescopic rod, and a second stator rotating rod is arranged on the side closer to the second telescopic rod.

[0025] The second pneumatic device includes a second telescopic cylinder and a third telescopic rod and a fourth telescopic rod arranged opposite to each other on both sides of the second telescopic cylinder. A third stator rotating rod is arranged on the side closer to the third telescopic rod, and a fourth stator rotating rod is arranged on the side closer to the fourth telescopic rod.

[0026] Furthermore, the bottom surface of the fixed base is provided with a rotating shaft to drive the fixed base to rotate.

[0027] Compared with the prior art, the beneficial effects of this application are as follows: In this winding mechanism, a fixed seat is used to house a pneumatic device, a first limiting member, and a second limiting member; the stator rotating rod passes through the fixed seat. The pneumatic device is connected to the first limiting member and is used to drive the first limiting member to extend and retract. The stator rotating rod is used to house the stator, and a second limiting member is fixedly installed on the stator rotating rod, with the second limiting member opposite to the first limiting member. When the first limiting member and the second limiting member are engaged, the stator rotating rod stops rotating; when the first limiting member and the second limiting member are misaligned, the stator rotating rod continues to rotate. This automatic winding mechanism, through the coordinated work of the fixed seat, the pneumatic device, the first limiting member, the stator rotating rod, and the second limiting member, enables stator winding during the operation of the stator winding equipment. Specifically, through the extension and retraction of the pneumatic device, the first limiting member and the second limiting member are engaged or misaligned, thereby enabling the stator rotating rod to rotate or remain stationary, thus achieving stator winding slot positioning during the rotation of the stator rotating rod, reducing manual intervention, and improving production efficiency.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0038] To achieve the above objectives, the technical solution of this utility model is as follows:

[0039] See Figures 1-8 As shown, this utility model provides a winding mechanism with a positioning structure, including: a fixed base 10, a pneumatic device 20, a first limiting member 30, a stator rotating rod 50, and a second limiting member 40; wherein,

[0040] The fixed base 10 is used to place the pneumatic device 20, the first limiting member 30 and the second limiting member 40, and the stator rotating rod 50 passes through the fixed base 10.

[0041] Pneumatic device 20 is connected to first limiting member 30 and is used to drive first limiting member 30 to extend and retract.

[0042] A stator rotating rod 50 is used to hold the stator. A second limiting member 40 is fixedly installed on the stator rotating rod 50, and the second limiting member 40 is arranged opposite to the first limiting member 30. When the first limiting member 30 and the second limiting member 40 are engaged, the stator rotating rod 50 stops rotating; when the first limiting member 30 and the second limiting member 40 are misaligned, the stator rotating rod 50 continues to rotate.

[0043] This automatic winding mechanism, through the coordinated operation of the fixed base 10, pneumatic device 20, first limiting member 30, stator rotating rod 50, and second limiting member 40, enables stator winding during the operation of the stator winding equipment. Specifically, through the telescopic movement of the pneumatic device 20, the first limiting member 30 and the second limiting member 40 engage or disengage, thereby allowing the stator rotating rod 50 to rotate or remain stationary. This achieves stator winding slot positioning during the rotation of the stator rotating rod 50, reducing manual intervention and improving production efficiency.

[0044] Furthermore, the second limiting member 40 includes:

[0045] The locking ring 41 has an annular opening with a notch, and fastening grooves 411 are provided at opposite ends of the notch for the fastening rod to pass through and fix the second limiting member 40 to the stator rotating rod 50.

[0046] The gear ring 42 is integrally connected with the locking ring 41. The outer surface of the gear ring is provided with spaced protrusions 421, and a limiting groove 422 is formed between two adjacent protrusions 421.

[0047] Furthermore, the first limiting member 30 includes a limiting protrusion 31, which corresponds to a limiting groove 422 formed on the outer surface of the gear ring 42, to lock or unlock the limiting groove 422, thereby realizing the rotation or stationary position of the stator rotating rod 50. Specifically, when the limiting protrusion 31 of the first limiting member 30 is engaged with the limiting groove 422 of the second limiting member 40, the stator rotating rod 50 is stationary; when the limiting protrusion 31 of the first limiting member 30 is misaligned with the limiting groove 422 of the second limiting member 40, the stator rotating rod 50 rotates.

[0048] Furthermore, the pneumatic device 20 includes a telescopic cylinder 21 and a telescopic rod 22 connected to the telescopic cylinder 21. The telescopic cylinder 21 is used to drive the telescopic rod 22 to perform telescopic movement, and a locking groove 221 is provided at the end of the telescopic rod 22.

[0049] The first limiting member 30 includes:

[0050] The fixing groove 32 has a receiving space for receiving the end of the telescopic rod 22;

[0051] A limiting part 322 is provided at the opening of the fixing groove 32 to embed the snap-fit groove 221 of the telescopic rod 22, thereby realizing the fixed connection between the first limiting member 30 and the pneumatic device 20.

[0052] Furthermore, a telescopic track 11 is formed on the fixed base 10, and the two sides of the first limiting member 30 abut against the side wall of the telescopic track 11 respectively, so as to prevent the first limiting member 30 from moving out of the preset track, which would cause the first limiting member 30 to fail to abut against the second limiting member 40 or fail to abut against the preset position of the second limiting member 40.

[0053] Furthermore, the stator rotating rod includes a first stator rotating rod 51 and a second stator rotating rod 52. The pneumatic device 20 includes a first telescopic rod 221 and a second telescopic rod 222 arranged opposite to each other on both sides of the telescopic cylinder 21. The first stator rotating rod 50 is arranged on the side closer to the first telescopic rod 221, and the second stator rotating rod 50 is arranged on the side closer to the second telescopic rod 222. By driving the first telescopic rod 221 and the second telescopic rod 222 with a single telescopic cylinder 21, costs are saved and efficiency is improved.

[0054] Furthermore, the stator rotating rod includes a first stator rotating rod 51, a second stator rotating rod 52, a third stator rotating rod 53 and a fourth stator rotating rod 54, which are respectively arranged around the fixed base 10;

[0055] The pneumatic device 20 includes a first pneumatic device 201 and a second pneumatic device 202, which are disposed on opposite sides of the fixed base 10.

[0056] The first pneumatic device 201 includes a first telescopic cylinder 211 and a first telescopic rod 221 and a second telescopic rod 222 arranged opposite to each other on both sides of the first telescopic cylinder 211. A first stator rotating rod 50 is arranged on the side closer to the first telescopic rod 221, and a second stator rotating rod 50 is arranged on the side closer to the second telescopic rod 222.

[0057] The second pneumatic device 202 includes a second telescopic cylinder 212 and a third telescopic rod 223 and a fourth telescopic rod 224 arranged opposite to each other on both sides of the second telescopic cylinder 212. A third stator rotating rod 50 is arranged on the side near the third telescopic rod 223, and a fourth stator rotating rod 50 is arranged on the side near the fourth telescopic rod 224.

[0058] Furthermore, a rotating shaft 60 is provided on the bottom surface of the fixed base 10 so as to drive the fixed base 10 to rotate.

[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
