Description

Technical Field

[0001] This utility model relates to the field of auxiliary fixture technology, and in particular to an auxiliary fixture for cutting the pins of electronic components. Background Technology

[0002] Auxiliary fixtures are tooling fixtures designed for specific machining processes. They are mainly used to assist in completing precise machining, assembly, and other operations. By providing functions such as positioning, fixing, and guiding, they optimize the production process and improve the accuracy, efficiency, and safety of machining. They are widely used in fields such as machinery manufacturing and electronic assembly.

[0003] In the process of cutting the leads of electronic components, auxiliary fixtures are indispensable. These fixtures can quickly and accurately clamp the components and fix them in the optimal cutting position, eliminating the need for repeated adjustments by the workers and greatly improving processing efficiency.

[0004] Currently, most auxiliary fixtures for cutting electronic component leads on the market use a bidirectional clamping method to fix the components. Although this method can achieve a basic fixing effect, during the actual cutting process, the squeezing force applied by the cutting equipment will be transmitted to the clamped electronic components, which can easily cause the electronic components to move axially, that is, shift in vertical position. Once the component position changes, the cutting tool cannot operate accurately according to the preset path, ultimately resulting in uneven lead cutting, affecting product quality and the stability of subsequent assembly processes. Therefore, an auxiliary fixture for cutting electronic component leads is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 An embodiment of this utility model provides an auxiliary fixture for cutting the pins of electronic components, including a positioning table 1. The positioning table 1 has a socket 2 for inserting pins. The pins of the electronic components are inserted into the socket 2. A portion extending to the bottom of the positioning table 1 is a cutting section. A positioning frame 3 is fixedly connected to the top of the positioning table 1. A sliding plate 4 is slidably connected to the inner wall of the positioning frame 3. A positioning mechanism 5 and an adjustment mechanism 6 are provided inside the positioning frame 3.

[0033] Reference Figures 2-3The positioning mechanism 5 includes a positioning plate 51, which is slidably connected to the inner wall of the slide plate 4. The positioning plate 51 has a U-shaped structure and can axially limit the electronic components. A spring 52 is fixedly connected to the bottom of the slide plate 4. The end of the spring 52 away from the slide plate 4 is fixedly connected to the inner wall of the positioning plate 51. The connection of the spring 52 allows the positioning plate 51 to move with the slide plate 4. A first threaded rod 53 is rotatably connected to the top of the slide plate 4. The end of the first threaded rod 53 away from the slide plate 4 passes through the positioning frame 3 and is fixedly connected to a knob 54. The first threaded rod 53 is threadedly connected to the through-hole of the positioning frame 3. By rotating the first threaded rod 53 with the knob 54, the first threaded rod 53, under the action of the threaded connection between the first threaded rod 53 and the positioning frame 3, can drive the slide plate 4 to slide up and down on the inner wall of the positioning frame 3. A rotating rod 55 is rotatably connected through the inner wall of the positioning plate 51. Gears 56 are fixedly connected to both ends of the rotating rod 55. A rack 57 that meshes with the gears 56 is fixedly connected to the lower surface of the sliding plate 4. When the positioning plate 51 is attached to the top of the electronic component, the rotating rod 55 can be rotated by the downward movement of the sliding plate 4 in conjunction with the rack 57 and gears 56. A crank arm 58 is fixedly connected to the outer wall of the rotating rod 55. A positioning rod 59 is fixedly connected to the end of the crank arm 58 away from the rotating rod 55. The positioning rod 59 can be attached to the side wall of the electronic component by swinging the crank arm 58 downward. Rubber pads 7 are fixedly connected to the lower surface of the positioning plate 51 and the outer wall of the positioning rod 59. The rubber pads 7 can not only increase the friction between the positioning plate 51, the positioning rod 59 and the electronic component to improve the stability of the electronic component, but also protect the electronic component and prevent it from being pinched.

[0034] Reference Figure 2 and Figure 4 The adjustment mechanism 6 includes a support plate 61, which is slidably connected to the inner wall of the positioning frame 3. The support plate 61 is located between the bottom of the positioning plate 51 and the top of the positioning platform 1. The distance between the support plate 61 and the positioning platform 1 can be adjusted by sliding the support plate 61 up and down on the inner wall of the positioning frame 3. The support plate 61 has a through hole 62 that matches the insertion hole 2. The through hole 62 and the insertion hole 2 are concentric. Inserting the pin of the electronic component into the through hole 62 allows it to be placed on the support plate 61. A second threaded rod 63 is rotatably connected to the upper surface of the support plate 61. The end of the second threaded rod 63 away from the support plate 61 passes through the positioning frame 3. The second threaded rod 63 is threadedly connected to the through point of the positioning frame 3. A handle 64 for rotating the second threaded rod 63 is fixedly connected to the top of the second threaded rod 63. By rotating the second threaded rod 63 through the handle 64, the second threaded rod 63 can drive the support plate 61 to slide up and down on the inner wall of the positioning frame 3 under the action of the threaded connection between the second threaded rod 63 and the positioning frame 3.

[0035] Working principle: When in use, insert the pins of the electronic components into the through hole 62 and place them on the upper surface of the support plate 61. At this time, the pins of the electronic components will be inserted into the socket 2 and extend to the bottom of the positioning platform 1. Then, the first threaded rod 53 can be rotated by the knob 54. Under the threaded connection between the first threaded rod 53 and the positioning frame 3, the rotation of the first threaded rod 53 can drive the slide plate 4 to slide down the inner wall of the positioning frame 3. As the slide plate 4 moves down, it will drive the positioning plate 51 to move down synchronously under the connection of the spring 52. By moving the positioning plate 51 down, the electronic components can be pressed down and pressed onto the upper surface of the support plate 61.

[0036] After the positioning plate 51 is attached to the top of the electronic component, the positioning plate 51 will be restricted by the electronic component, so that the positioning plate 51 can no longer move downward. At this time, the first threaded rod 53 is rotated by the knob 54, so that the first threaded rod 53 continues to drive the slide plate 4 to slide downward and compress the spring 52. While the slide plate 4 slides downward, it will drive the rack 57 to move downward synchronously. Since the positioning plate 51 can no longer move downward, the height of the rotating rod 55 remains unchanged. As the rack 57 moves downward, it can drive the rotating rod 55 to rotate on the inner wall of the positioning plate 51 in conjunction with the gear 56 meshing with it. While the rotating rod 55 is rotating, it will drive the crank arm 58 to swing downward.

[0037] At this time, the crank arm 58 will drive the positioning rod 59 to swing downward until the positioning rod 59 drives the rubber pad 7 on its outer wall to stick tightly to both sides of the electronic component. At this time, the two sets of positioning rods 59 can clamp the two sides of the electronic component. At the same time, with the help of the positioning plate 51, the electronic component can be pressed down on the support plate 61, thereby axially limiting the electronic component. This prevents the electronic component from moving up and down when the pin is cut, which helps to improve the cutting quality of the pin. At this time, the cutting equipment can be used to cut the pin that extends from the bottom of the positioning table 1.

[0038] When the positioning plate 51 is attached to the top of the electronic component and the positioning rods 59 are clamped on both sides of the electronic component, the positioning plate 51 cannot move downwards. Under the meshing action of the gear 56 and the rack 57, the positioning plate 51 can no longer move upwards. At this time, by using the two sets of positioning rods 59 in conjunction with the positioning plate 51 and the support plate 61, the electronic component can be effectively limited around its perimeter, effectively preventing the electronic component from shifting.

[0039] After the pins of the electronic component are cut, the first threaded rod 53 is rotated by the knob 54, causing the slide plate 4 to move upward on the inner wall of the positioning frame 3. As the slide plate 4 moves upward, the rack 57 moves upward synchronously. As the rack 57 moves upward, it works with the gear 56 to drive the rotating rod 55 to rotate on the inner wall of the positioning plate 51. At the same time, the rotating rod 55 drives the crank arm 58 to swing upward. As the crank arm 58 swings upward, it drives the positioning rod 59 to disengage from both sides of the electronic component. As the slide plate 4 moves upward, it works with the spring 52 to drive the positioning plate 51 to move upward, thereby allowing the positioning plate 51 to disengage from the top of the electronic component. At this point, the clamping of the electronic component can be released, and the electronic component can be removed from the support plate 61.

[0040] By rotating the second threaded rod 63 through the handle 64, the second threaded rod 63 can drive the support plate 61 to slide up and down on the inner wall of the positioning frame 3 under the action of the threaded connection between the second threaded rod 63 and the positioning table 1. This allows the distance between the support plate 61 and the positioning table 1 to be adjusted. When the pin of the electronic component is inserted into the through hole 62, the insertion depth of the pin in the insertion hole 2 can be adjusted by adjusting the height of the support plate 61. This allows the length of the pin extending to the bottom of the positioning table 1 to be adjusted so as to accurately control the length of the pin extending out of the positioning table 1 according to the cutting requirements, thereby further improving the cutting quality of the pin.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
