Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and in particular to a winding clamp mechanism for a stranding machine. Background Technology

[0002] In the production of electrical equipment such as motors and transformers, the winding process is one of the key steps. Traditional winding chuck mechanisms typically use threaded or pneumatic clamping methods, but these suffer from uneven clamping force and low positioning accuracy. Furthermore, existing chuck mechanisms lack reliable positioning devices when not in a winding state, which can easily lead to accidental rotation of the rotating shaft, affecting operational safety and efficiency. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a winding clamp mechanism with self-locking function, adaptive clamping, and a double wire fixing structure, thus solving the problems of unstable positioning, uneven clamping force, and easy wire detachment in the prior art.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A winding clamp mechanism includes a fixed base, a rotating shaft, a positioning block, a clamp assembly, and two sets of wire clamp assemblies. The rotating shaft is rotatably mounted on the fixed base, the clamp assembly is mounted on the end of the rotating shaft, and the two sets of wire clamp assemblies are symmetrically mounted on the clamp assembly. The fixed base has a through slot, the positioning block is placed in the through slot and can move along the through slot, the positioning block has a positioning groove, and the rotating shaft has a flat position that cooperates with the positioning groove. When the clamp assembly is in a non-winding state, the flat position engages with the positioning groove to restrict the rotation of the rotating shaft.

[0006] Furthermore, the chuck assembly includes a fixed sleeve, an inner sleeve, an outer sleeve, and a clamping head; the rotating shaft is inserted into one end of the fixed sleeve and fixed by a pin, the inner sleeve is inserted into the other end of the fixed sleeve and fixed by a pin; one end of the clamping head is inserted into the inner sleeve and fixed by a pin, one end of the outer sleeve is sleeved on the outside of the inner sleeve, and the other end of the outer sleeve abuts against the other end of the clamping head.

[0007] Furthermore, the inner sleeve of the clamp includes a first connecting part, a first sleeve part, and a second sleeve part, and the outer sleeve of the clamp includes a second connecting part, a third sleeve part, and a fourth sleeve part. The first sleeve part is inserted into the fixed sleeve and fixed by a pin. The third sleeve part is sleeved with the second sleeve part, and the fourth sleeve part abuts against the other end of the clamping head.

[0008] Furthermore, the clamping head includes an arm base, multiple sets of clamping arms, and a top core. One end of the arm base is inserted into the inner sleeve of the clamp and fixed by a pin. The top core is inserted into the arm base. The multiple sets of clamping arms are arranged around the other end of the arm base and surround the top core. Each end of the multiple sets of clamping arms away from the arm base is provided with a clamping block. The clamping blocks of the multiple sets of clamping arms together form a clamping station for clamping the component to be wound.

[0009] Furthermore, the outer side of the clamping block is an annular inclined surface, and the inner wall of the fourth sleeve abuts against the annular inclined surface on the outer side of the clamping block.

[0010] Furthermore, the rotating shaft is rotatably mounted on the fixed base via a bearing seat. The through slot is opened at one end of the fixed base away from the chuck assembly. A first spring is provided at the bottom of the through slot. The positioning block is placed in the through slot and the bottom end of the positioning block abuts against the first spring. By compressing or releasing the first spring, the positioning block is driven to move in the through slot, thereby realizing the fixing and loosening of the rotating shaft.

[0011] Furthermore, the positioning block includes a vertical block and a horizontal block disposed on the upper end of the vertical block. The vertical block is located in the through groove, and the bottom end of the vertical block abuts against the first spring.

[0012] Furthermore, the flat position is located at the end of the rotating shaft away from the chuck assembly, and the positioning groove is formed on the horizontal block. When the chuck assembly is in a non-winding state, the flat position of the rotating shaft is engaged in the positioning groove of the horizontal block.

[0013] Furthermore, both sets of the wire clamp assemblies include a wire clamp base installed on the fixed sleeve. Two wire clamping arms are symmetrically arranged on the wire clamp base, forming a clamping space between the two wire clamping arms. A wire clamping fixing sleeve is provided on the two wire clamping arms. A movable pin is movably installed inside the wire clamping fixing sleeve. The pin cap at the front end of the movable pin faces the clamping space. The gap between the pin cap of the movable pin and the wire clamping arm forms a wire clamping position. The rear end of the movable pin passes through the wire clamping fixing sleeve, and a second spring is sleeved on the rear end of the movable pin. One end of the second spring is connected to the tail of the movable pin, and the other end of the second spring abuts against the wire clamping fixing sleeve.

[0014] Furthermore, the winding chuck mechanism also includes a drive wheel, which is mounted on the rotating shaft and located between the positioning block and the chuck assembly.

[0015] The beneficial effects of this utility model are:

[0016] 1. The chuck assembly, through its multi-stage sleeve structure and the engagement of the clamping block with the annular inclined surface of the clamping outer sleeve, can uniformly and stably clamp the winding component, effectively preventing loosening and displacement of the component during the winding process and improving the winding quality.

[0017] 2. The positioning block and the rotating shaft are aligned and positioned in a groove, which can restrict the rotation of the rotating shaft in the non-winding state, making it easier for other processes to operate and maintain, while ensuring the stability and safety of the equipment.

[0018] 3. Two sets of symmetrically arranged wire clamp assemblies can assist in fixing the winding material, and together with the clamp assembly, improve the winding efficiency; at the same time, the wire clamp assembly adopts a spring-driven movable pin structure, which is easy to operate and can quickly clamp and release the winding material.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the above terms in this utility model according to the specific circumstances.

[0036] Please see Figures 1 to 4As shown, this embodiment of the utility model provides a wire winding clamp mechanism, including a fixed base 10, a rotating shaft 20, a positioning block 40, a clamp assembly 30, two sets of wire clamp assemblies 50, and a drive wheel 70. Wherein:

[0037] The fixed base 10 serves as the basic support component of the entire mechanism. A through slot 11 is provided on the fixed base 10 to provide a moving track for the positioning block 40. The first spring 12 is located at the bottom of the through slot 11 and drives the positioning block 40 to move up and down by compression or recovery deformation.

[0038] The rotating shaft 20 is rotatably mounted on the fixed base 10 via the bearing housing 60, effectively reducing rotational friction and ensuring smooth rotation of the rotating shaft 20. One end of the rotating shaft 20 is connected to the chuck assembly 30 for stable clamping of the winding component; the other end is provided with a flat position 21 that cooperates with the positioning block 40 to realize the switching between working and non-working states.

[0039] The drive wheel 70 is mounted on the rotating shaft 20 and located between the positioning block 40 and the chuck assembly 30. It is connected to an external power source through gear transmission to provide rotational power for the winding operation.

[0040] Please see Figures 1 to 7 As shown, in this embodiment, the clamp assembly 30 includes a fixed sleeve 31, an inner clamp sleeve 32, an outer clamp sleeve 33, and a clamping head 34. The components cooperate with each other to achieve stable clamping of the winding component.

[0041] The fixed sleeve 31 serves as the basic connecting component of the chuck assembly 30. One end is fixed to the rotating shaft 20 by a pin 36, and the other end is fixed to the inner sleeve 32 of the clamp to ensure the stability of power transmission.

[0042] The inner sleeve 32 of the clamp includes a first connecting part 321, a first sleeve part 322 and a second sleeve part 323. The first sleeve part 322 is inserted into the fixed sleeve 31 and fixed by the pin 36. The second sleeve part 323 cooperates with the outer sleeve 33 of the clamp. Its internal space is used to install the clamping head 34 and provide guidance and support.

[0043] The clamp outer sleeve 33 includes a second connecting part 331, a third sleeve part 332, and a fourth sleeve part 333. The third sleeve part 332 is sleeved on the outside of the second sleeve part 323, and the inner wall of the fourth sleeve part 333 engages with the outer annular inclined surface of the clamping block 344 of the clamping head 34. When the clamp outer sleeve 33 moves axially, the clamping block 344 retracts inward through the squeezing action of the inclined surface, thereby achieving adaptive clamping of the winding component.

[0044] The clamping head 34 includes an arm base 341, three sets of clamping arms 342, and a top core 343. The arm base 341 is inserted into the inner sleeve 32 of the clamp and fixed by a pin 36. The top core 343 is located inside the arm base 341 and provides support. The three sets of clamping arms 342 are located at the other end of the arm base 341 and surround the top core 343. Each clamping arm 342 has a clamping block 344 at the end away from the arm base 341. The three sets of clamping arms 342 are arranged in a circular array, and the clamping blocks 344 at the ends form a clamping station 35 for fixing the part to be wound. The annular inclined surface on the outer side of the clamping block 344 cooperates with the fourth socket 333 of the outer sleeve 33 of the clamp to ensure uniform distribution of clamping force.

[0045] Please see Figures 1 to 4 As shown, in this embodiment, the positioning block 40 includes a vertical block 41 and a horizontal block 42. The vertical block 41 is placed in the through groove 11 of the fixing base 10, and its bottom end abuts against the first spring 12 in the through groove 11. The horizontal block 42 has a positioning groove 43. When the chuck assembly 30 is in a non-winding state, the first spring 12 is in its natural state, the positioning block 40 moves upward, and the flat part 21 of the rotating shaft 20 is engaged in the positioning groove 43, restricting the rotation of the rotating shaft 20; when winding, the positioning block 40 is moved downward by external force to compress the spring, the flat part 21 is disengaged from the positioning groove 43, and the rotating shaft 20 resumes free rotation.

[0046] Please see Figures 1 to 2 As shown, in this embodiment, two sets of wire clamp assemblies 50 are symmetrically mounted on the fixed sleeve 31. Each assembly includes a wire clamp base 51 mounted on the fixed sleeve 31. Two wire clamping arms 52 are symmetrically arranged on the wire clamp base 51, forming a clamping space between the two wire clamping arms 52 for accommodating the wire. Fixed sleeves 53 are arranged opposite to each other on the two wire clamping arms 52. A movable pin 54 is movably mounted inside the fixed sleeve 53. The pin cap at the front end of the movable pin 54 faces the clamping space. The gap between the pin cap of the movable pin 54 and the wire clamping arm 52 forms a clamping station for direct contact with the wire and clamping. The rear end of the movable pin 54 passes through the fixed sleeve 53. A second spring 55 is sleeved on the rear end of the movable pin 54. One end of the second spring 55 is connected to the tail of the movable pin 54, and the other end abuts against the fixed sleeve 53. The second spring 55 provides elastic restoring force for the movable pin 54.

[0047] In this embodiment, before the winding operation begins, the clamp assembly 30 is stationary, and the second spring 55 of the movable pin 54 is in its natural state. When the winding operation is required, the clamp assembly 30 is activated, rotating the two sets of wire clamp assemblies 50 to their upper and lower positions. An external holding force clamps the movable pin 54 of the wire clamp assembly 50, and the wire is fed to the clamping position of the lower wire clamp assembly 50. The external holding force then releases the movable pin 54, and the wire is clamped and fixed within the gap between the pin cap and the clamping arm 52. Specifically, the external holding force clamps the movable pin 54, overcoming the elastic restoring force of the second spring 55, causing the movable pin 54 to move into the clamping space, thereby widening the gap between the pin cap and the clamping arm 52, making it easier for the wire to enter the clamping position. After the wire is fed into the clamping position, the external holding force releases the movable pin 54, and under the elastic restoring force of the second spring 55, the gap between the pin cap and the clamping arm 52 narrows, thereby clamping one end of the wire. After the winding work is completed, the upper wire clamp assembly 50 clamps the other end of the wire in a similar manner.

[0048] In practical applications, this utility model's winding chuck mechanism, through its ingenious structural design, achieves stable clamping, convenient operation, and good adaptability to different components. In the non-winding state, the rotating shaft can be accurately positioned, ensuring the stability of the chuck assembly. During winding, the chuck assembly can quickly and accurately clamp components of various sizes to be wound, while the wire clamp assembly stably delivers the wire, providing strong support for efficient and high-quality winding operations. It effectively solves many problems existing in current winding chuck mechanisms and has significant practical value and promising prospects for widespread application.

[0049] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
