Description

Technical Field

[0001] This utility model relates to the field of chamfering tooling technology, specifically an automatic winding chamfering tooling. Background Technology

[0002] Currently, the input and output wires of flat-wire vertically wound inductors are cut at right angles. During inductor use, these right-angled sections are prone to damaging the surrounding insulation material. To prevent short circuits and other faults during operation, a significant amount of insulation material is typically used to protect the inductor. However, even with ample insulation, the right angles at the cuts can still pierce the protective layer, leading to a decrease in the inductor's insulation performance, increasing the risk of inductor failure, and in severe cases, even causing safety accidents and affecting the normal operation of new energy equipment.

[0003] Currently, the industry commonly uses manual rounding of flat wires, which can reduce damage to the insulation material from right angles and improve the insulation performance of inductors to some extent. However, manual rounding is inefficient, requiring a significant investment of manpower and time in large-scale production. Due to factors such as operator skill level and work attitude, the size and shape of the rounded corners can vary considerably, failing to meet uniform standards and thus affecting the consistency and reliability of inductor performance. Utility Model Content

[0004] To address the aforementioned shortcomings, this utility model proposes an automatic winding chamfering fixture, aiming to solve the problem of unstable quality in traditional manual chamfering processes.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An automatic winding and chamfering fixture includes a base, a stamping power assembly, a cutting tool, and a limiting member. The mounting end of the stamping power assembly is fixedly installed at the rear end of the base, and the movable end of the stamping power assembly is hinged to the top of the cutting tool. The limiting member is fixedly installed at the front end of the base. The limiting member is provided with a first groove and a second groove. The first groove vertically penetrates the top and bottom of the limiting member, and the second groove horizontally penetrates the front side of the limiting member. The rear ends of the first groove and the second groove are interconnected.

[0007] The first groove is slidably connected to the cutting tool, and the second groove is used to place the workpiece horizontally.

[0008] The stamping power assembly includes a stamping power component, a stamping connecting rod, and a stamping support rod. The movable end of the stamping power component is hinged to the rear end of the stamping connecting rod, the front end of the stamping connecting rod is hinged to the top of the cutting tool, and the top of the stamping support rod is hinged to the middle part of the stamping connecting rod.

[0009] The base has a discharge component at its bottom, and the discharge component has a discharge trough. The discharge trough includes a vertical part and an inclined part from top to bottom. The top of the vertical part is connected to the bottom of the first trough body, and the bottom of the vertical part is connected to the top of the inclined part. The bottom of the inclined part obliquely penetrates the side wall of the discharge component.

[0010] Both ends of the cutting tool are recessed inward to form recessed portions, and the front and rear ends of the recessed portions are smoothly connected to the sidewalls of the cutting tool, respectively.

[0011] The first groove body has protrusions on both the left and right inner walls. The front and rear ends of the protrusions are smoothly connected to the inner walls of the first groove body, and the protrusions and the recesses are adapted to each other and slidably connected.

[0012] The side wall of the discharge component is provided with a material collection frame, which is located directly below the bottom of the discharge trough.

[0013] The second groove divides the limiting member into a guide portion and a support portion. The length of the guide portion in the front-back direction is shorter than the length of the support portion. The limiting member forms an upwardly tapering stepped structure.

[0014] The base is horizontally provided with a positioning block, the left end of the positioning block protrudes from the base, and the bottom of the positioning block is provided with a downward-facing positioning groove, which horizontally passes through the front and rear sides of the positioning block.

[0015] The technical solution of this utility model can include the following beneficial effects:

[0016] 1. The first groove extends vertically through the top and bottom of the limiting member, and the rear end of the second groove is connected to the first groove. Therefore, a workpiece is placed in the second groove, and then the stamping power assembly is activated. The stamping power assembly drives the cutting tool to slide downward in the first groove, so that the cutting tool presses down against the workpiece within the limiting member, thereby completing the chamfering process of the workpiece.

[0017] 2. The cutting tool slides in the first groove, ensuring the accuracy of the tool's movement trajectory; the workpiece is placed in the second groove, which ensures the stability of the workpiece's position during the processing, reducing quality problems such as uneven chamfering and large dimensional deviations caused by tool shaking or workpiece displacement. This effectively improves the accuracy of chamfering, resulting in better dimensional consistency and more reliable quality of the processed products, solving the problem of unstable quality in traditional manual chamfering.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The following is combined Figures 1 to 4 This describes an automatic winding and chamfering fixture according to an embodiment of the present invention.

[0028] An automatic winding and chamfering fixture includes a base 1, a stamping power assembly 2, a cutter 3, and a limiting member 4. The mounting end of the stamping power assembly 2 is fixedly installed at the rear end of the base 1, and the movable end of the stamping power assembly 2 is hinged to the top of the cutter 3. The limiting member 4 is fixedly installed at the front end of the base 1. The limiting member 4 is provided with a first groove 41 and a second groove 42. The first groove 41 vertically penetrates the top and bottom of the limiting member 4, and the second groove 42 horizontally penetrates the front side of the limiting member 4. The rear ends of the first groove 41 and the second groove 42 are interconnected.

[0029] The first groove 41 is slidably connected to the cutting tool 3, and the second groove 42 is used to place the workpiece horizontally.

[0030] The first groove 41 vertically penetrates the top and bottom of the limiting member 4, and the rear end of the second groove 42 is connected to the first groove 41. Therefore, a workpiece is placed in the second groove 42, and then the stamping power assembly 2 is activated. The stamping power assembly 2 drives the cutting tool 3 to slide downward in the first groove 41, so that the cutting tool 3 presses the workpiece downward in the limiting member 4, thereby completing the chamfering process of the workpiece.

[0031] It is worth noting that the tool 3 slides within the first groove 41, ensuring the accuracy of the tool 3's movement trajectory; the workpiece is placed in the second groove 42, which ensures the stability of the workpiece's position during processing, reducing quality problems such as uneven chamfering and large dimensional deviations caused by tool 3 shaking or workpiece displacement. This effectively improves the accuracy of chamfering, resulting in better dimensional consistency and more reliable quality of the processed products, solving the problem of unstable quality in traditional manual chamfering.

[0032] The stamping power assembly 2 includes a stamping power component 21, a stamping connecting rod 22, and a stamping support rod 23. The movable end of the stamping power component 21 is hinged to the rear end of the stamping connecting rod 22, the front end of the stamping connecting rod 22 is hinged to the top of the cutter 3, and the top of the stamping support rod 23 is hinged to the middle part of the stamping connecting rod 22.

[0033] It is worth noting that the stamping power component 21 is a vertically positioned cylinder. The piston rod of the stamping power component 21 extends upwards, causing the rear end of the stamping connecting rod 22 to tilt upwards. Since the stamping support rod 23 is hinged to the middle of the stamping connecting rod 22, it becomes the key fulcrum for this lever action. The power output from the stamping power component 21 is transmitted through the stamping connecting rod 22 and amplified by the lever action of the stamping support rod 23, allowing the tool 3 to obtain a greater force than if the stamping power component 21 were directly output. This enables it to easily handle workpiece materials of different hardness and thickness, effectively improving chamfering capabilities and broadening the applicability of the tooling.

[0034] In addition, workers can adjust the hinge position of the stamping support rod 23 and the stamping connecting rod 22 to change the lever arm ratio, thereby precisely controlling the pressure applied to the workpiece by the tool 3.

[0035] The bottom of the base 1 is provided with a discharge component 5, and the discharge component 5 is provided with a discharge trough 51. The discharge trough 51 includes a vertical part 52 and an inclined part 53 from top to bottom. The top of the vertical part 52 is connected to the bottom of the first trough 41, and the bottom of the vertical part 52 is connected to the top of the inclined part 53. The bottom of the inclined part 53 obliquely penetrates the side wall of the discharge component 5.

[0036] The vertical part 52 is connected to the first groove 41, allowing waste generated during the chamfering process to fall quickly and directly into the discharge groove 51, avoiding the accumulation of waste in the first groove 41. The inclined part 53 slopes outward from top to bottom, allowing waste to slide quickly out of the discharge groove 51 along the inner wall of the inclined part 53 under the force of its own gravity, achieving continuous and efficient discharge of waste, greatly improving the discharge efficiency in the production process, and reducing production interruptions and cleaning time caused by waste accumulation.

[0037] Both ends of the cutting tool 3 are recessed inward to form recessed portions 31, and the front and rear ends of the recessed portions 31 are smoothly connected to the sidewalls of the cutting tool 3, respectively.

[0038] The first groove 41 has protrusions 411 on both the left and right inner walls. The front and rear ends of the protrusions 411 are smoothly connected to the inner walls of the first groove 41. The protrusions 411 and the recesses 31 are adapted to each other and slidably connected.

[0039] During the stamping process, the cutting tool 3 presses downward against the workpiece. Due to the smooth connection of the recessed portion 31 on the cutting tool 3, the end of the workpiece naturally forms a smooth edge, thereby completing the chamfering process. The mutual adaptation design of the recessed portion 31 and the protrusion 411 makes the assembly process of the cutting tool 3 and the first groove 41 simple and quick.

[0040] When assembling the chamfering fixture of this utility model, simply align the recessed part 31 of the tool 3 with the protrusion 411 of the first groove 41 and gently insert it to complete the assembly. There is no need for complicated adjustments and centering operations, which greatly improves the assembly efficiency and reduces the assembly time and labor costs. It is especially suitable for large-scale production and frequent tool 3 replacement scenarios.

[0041] The side wall of the discharge component 5 is provided with a collection frame 6, which is located directly below the bottom of the discharge trough 51.

[0042] The collection frame 6 is located directly below the bottom of the discharge chute 51, ensuring that the waste material can accurately enter the collection frame 6 during the discharge process. This eliminates the possibility of waste material being missed due to splashing or falling during the discharge process, improves the integrity and thoroughness of waste material collection, and reduces the difficulty and workload of subsequent cleaning work.

[0043] The second groove 42 divides the limiting member 4 into a guide portion 43 and a support portion 44. The length of the guide portion 43 in the front-back direction is shorter than the length of the support portion 44. The limiting member 4 forms an upwardly tapering stepped structure.

[0044] Traditional tooling designs, due to structural limitations, may require users to maintain uncomfortable postures such as bending over and tilting their heads for extended periods to inspect the workpiece inside the slot. This not only easily leads to physical fatigue but may also cause pain and injury in the neck, lower back, and other areas. In this design, the guide section 43 is shorter than the support section 44, allowing users to observe in a more natural and relaxed posture. This effectively reduces physical burden, lowers fatigue caused by prolonged operation, and ensures user comfort and health during extended work periods, reflecting a human-centered design philosophy.

[0045] In addition, the guide part 43 provides precise guidance for the placement and movement of the workpiece, ensuring that the workpiece can enter the processing position accurately; the support part 44 undertakes the important task of firmly supporting the workpiece, ensuring that the workpiece will not shake or shift during processing, and improving the efficiency of the second groove 42 for placing the workpiece.

[0046] The base 1 is horizontally provided with a positioning block 7. The left end of the positioning block 7 extends out of the base 1. The bottom of the positioning block 7 is provided with a downward-facing positioning groove 71. The positioning groove 71 horizontally extends through the front and rear sides of the positioning block 7.

[0047] By connecting to an external device through the positioning groove 71, the base 1 can be tightly integrated with a larger structural system, which can eliminate the risk of displacement of the base 1 caused by processing vibration and impact, and improve the processing accuracy of the chamfering fixture of this utility model, especially suitable for high frequency and high pressure stamping scenarios.

[0048] It is worth noting that the automatic winding and chamfering fixture in this solution can be installed in an automatic winding machine. During the wire feeding process, the flat wire workpiece requiring winding and chamfering passes through the second groove 42. When the chamfering process is required, the stamping power assembly 2 is activated, and the cutter 3 presses downwards against the flat wire workpiece within the limiting member 4, thereby completing the chamfering process of the flat wire workpiece during the winding process, improving production efficiency, and eliminating the need for manual placement of the flat wire workpiece in the second groove 42.

[0049] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
