Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a solder cup plane trimming device. Background Technology

[0002] In the manufacturing process of electronic components, the solder cup is a key welding part between connectors and wire harnesses, and its flatness directly affects the welding quality and conductivity. Currently, the industry commonly uses tin-lead alloy or copper alloy materials to make solder cups. However, because oxide slag and burrs are generated during the welding process, the surface of the solder cup needs to be precisely trimmed before welding.

[0003] In the past, various methods were commonly used in the industry to finish the surface of welding cups. One common method was manual grinding, where workers used sandpaper, grinding wheels, and other tools to manually grind the surface of the welding cup. This method allowed for flexible adjustment of the grinding force and range according to the actual situation. Another method was to use ordinary milling equipment to mill the surface of the welding cup with a milling cutter. This method could achieve a certain degree of automation and improve processing efficiency. Some companies also used electrical discharge machining (EDM), which used the high temperature generated by electrical discharge to etch and finish the surface of the welding cup. This method was suitable for processing materials with high hardness.

[0004] However, these existing conventional methods have significant drawbacks. Manual grinding is not only labor-intensive and inefficient, but also struggles to guarantee the precision and consistency of the finishing, easily resulting in uneven surfaces. While ordinary milling equipment improves efficiency to some extent, its machining accuracy and flexibility are poor for small or complex-shaped welding cups. Electrical discharge machining (EDM) suffers from high equipment costs and slow processing speeds, and it can also cause heat-affected zones on the welding cup surface, impacting its performance.

[0005] Therefore, how to design a welding cup flat trimming device that can improve processing efficiency, processing accuracy and flexible applicability is a technical problem that urgently needs to be solved. Utility Model Content

[0006] The purpose of this application is to overcome the above-mentioned technical problems and provide a welding cup plane trimming device that can improve the processing efficiency, processing accuracy and flexible applicability of the welding cup plane.

[0007] This application discloses a welding cup flat surface trimming device, which specifically adopts the following solution:

[0008] A welding cup flat trimming device includes: a base with a slide rail at one end; a cutting assembly including a motor and a cutting element, the motor being disposed at the other end of the base and opposite to the slide rail, the cutting element being located above the slide rail and having one end connected to the motor; a clamping mechanism including a sliding block and a clamping adjustment assembly, one end of the sliding block being embedded in the slide rail, and the clamping adjustment assembly being disposed at the end of the sliding block away from the base for adjustable clamping of the welding cup; and a pushing assembly located at the end of the sliding block away from the cutting assembly, including: a fixed column and a pushing shaft, one end of the fixed column being fixed to the base, and the other end being through which one end of the pushing shaft passes to connect and push the sliding block on the slide rail to drive the clamping adjustment assembly to clamp the welding cup toward the cutting element.

[0009] By adopting the above technical solution, a slide rail is set at one end of the base, which provides a sliding path and support for the sliding block, ensuring its stable movement. The motor of the cutting component is set at the other end of the base opposite to the slide rail, so that the cutting part is in a suitable position, which facilitates the cutting operation of the welding cup. At the same time, the motor provides power to the cutting part to realize the trimming of the welding cup surface. The sliding block of the clamping mechanism is embedded in the slide rail and can move smoothly along the slide rail. The clamping adjustment component is set at the end of the sliding block away from the base, which can adjust the clamping of the welding cup to adapt to welding cups of different sizes, ensuring the stability of the welding cup during the trimming process, and enhancing the applicability of the equipment to welding cups of different sizes. One end of the fixed column of the pushing component is fixed to the base, and the other end is through which the pushing shaft passes. The pushing shaft abuts against and pushes the sliding block to move on the slide rail, thereby driving the welding cup held by the clamping adjustment component to move towards the cutting part, ensuring that the welding cup is accurately close to the cutting part for the surface trimming operation, so as to improve the efficiency and quality of welding cup surface trimming.

[0010] Optionally, the clamping adjustment assembly includes: a rotating shaft passing through the sliding block, with both ends exposed outside the sliding block and connected to a knob, wherein the sliding block is provided with a slot for the rotating shaft to pass through; two support seats, passing through both ends of the rotating shaft and moving relative to each other on the sliding block, and correspondingly provided with opposing reverse threads on the rotating shaft for one end of the two support seats to be fitted; and two clamping members, respectively disposed opposite to each of the two support seats and opposite to the cutting part, wherein the rotation of the knob drives the rotating shaft to rotate, thereby driving the two support seats to move relative to each other, so as to realize the adjustable clamping of the welding cup by the clamping members.

[0011] By adopting the above technical solution, the equipment can drive the rotating shaft to rotate by rotating the knob, so that the two support seats move relative to each other on the sliding block, thereby realizing the adjustable clamping of the welding cup by the clamping component. This facilitates flexible clamping operations of welding cups of different sizes and specifications. In addition, the cutting component set on the base can perform planar trimming on the clamped welding cup, and the pushing component can push the sliding block to move the welding cup toward the cutting component for processing.

[0012] Optionally, the clamping adjustment assembly further includes: two fasteners, which are respectively covered at both ends of the slot and fixed on the sliding block, and the fasteners are provided with through holes for the rotating shaft to pass through to connect the knob.

[0013] By adopting the above technical solution, the fastener can be fixed on the sliding block and cover both ends of the slot. Its through hole allows the rotating shaft to pass through and connect the knob. This not only ensures the stability of the rotating shaft installation position and prevents the rotating shaft from detaching from the sliding block and affecting its use, but also provides a stable channel for the connection between the knob and the rotating shaft, making the process of the knob rotating to drive the rotating shaft to rotate smoother, thereby improving the stability and reliability of the entire clamping and adjusting assembly.

[0014] Optionally, the clamping adjustment assembly further includes a spring element, which is sleeved on the rotating shaft and located in the slot, with its two ends respectively abutting against the two support seats.

[0015] By adopting the above technical solution, the spring component sleeved on the rotating shaft and abutting against the two support seats at both ends can play a buffering role when adjusting the clamping component to clamp the welding cup, avoiding excessive clamping and damage to the welding cup, and making the clamping process more stable and reliable.

[0016] Optionally, the clamping adjustment assembly further includes a cover plate disposed on the sliding block, located between the two support seats and covering the slot.

[0017] By adopting the above technical solution, the cover plate can prevent external debris from entering the slot, ensure the normal operation of components such as the rotating shaft, and improve the reliability and stability of the clamping and adjusting components.

[0018] Optionally, the clamping member includes: an abutment, a screw, and a clamping plate. One end of the abutment is integrally connected to the screw to pass through the support seat and is fixed by a nut. The end of the abutment away from the screw is detachably connected to the clamping member. The two support seats move to drive the two clamping members to move closer together.

[0019] By adopting the above technical solution, the clamping parts are easy to install and disassemble, and easy to replace and maintain. At the same time, the two clamping parts are staggered and close together to clamp the welding cup more stably.

[0020] Optionally, multiple clamping plates are provided on each of the support seats.

[0021] By adopting the above technical solution, multiple clamping plates are set on each support, which increases the contact area with the welding cup, making the clamping more stable and reliable, and improving the stability and accuracy of the welding cup surface trimming.

[0022] Optionally, a rotating handle is provided at the end of the push shaft away from the sliding block, and the push shaft and the fixed column are rotated by thread engagement.

[0023] By adopting the above technical solution, a rotating handle is set to facilitate the operation of the push shaft. The push shaft and the fixed column are rotated through a threaded connection, which can stably and accurately push the sliding block to move on the slide rail, so that the clamping and adjusting assembly can clamp the welding cup and move it toward the cutting workpiece.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By pushing the component, the sliding block drives the clamping and adjusting component to move the welding cup towards the cutting workpiece for finishing, avoiding manual grinding, reducing labor intensity, and improving processing efficiency, finishing accuracy and consistency;

[0026] 2. The adjustable clamping and adjustment assembly can clamp welding cups of different sizes and shapes, improving the flexibility and applicability of the equipment processing;

[0027] 3. This equipment trims the surface of the welding cup through the cutting component. Compared with ordinary milling equipment, it is more suitable for small or complex-shaped welding cups. Compared with EDM equipment, it has lower cost, faster processing speed, and does not cause heat effects on the surface of the welding cup. Attached Figure Description

[0033] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0034] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0035] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0036] See Figure 1 and Figure 2 This application discloses a welding cup plane trimming device, which includes a base 10, a cutting component 20, a clamping mechanism 30, and a pushing component 40. The cutting component 20 is located at one end of the base 10 and is used to trim the welding cup. The clamping mechanism 30 is disposed on the pushing component 40 and is used to clamp the welding cup. The pushing component 40 is disposed at the other end of the base 10 and is disposed opposite to the cutting component 20. It is used to push the clamping mechanism 30 to move the welding cup toward the cutting component 20.

[0037] A slide rail 11 is provided at one end of the base 10, and a clamping mechanism 30 is embedded in the slide rail 11 and is pushed by the pushing component 40 to slide relative to the slide rail 11. The cutting component 20 includes a motor 21 and a cutting element 22. The motor 21 is located at the other end of the base 10 opposite to the slide rail 11. One end of the cutting element 22 is connected to the motor 21 and is located above the slide rail 11. It is used to rotate the cutting element 22 when the motor 21 is started, so that the other end of the cutting element 22 can cut and trim the welding cup. The rotation speed of the cutting element 22 driven by the motor 21 can be adjusted according to actual needs. In this embodiment, a start switch and a speed adjustment switch can be provided. In addition, the appearance structure of the cutting element 22 can be described as follows. Figure 2 As shown in the image.

[0038] The clamping mechanism 30 includes a sliding block 31 and a clamping adjustment assembly 32. One end of the sliding block 31 is embedded in the slide rail 11, and the clamping adjustment assembly 32 adjustably clamps the welding cup on the sliding block 31. The pushing assembly 40 is located at the end of the sliding block 31 away from the cutting assembly 20, and includes a fixed post 41 and a pushing shaft 42. One end of the fixed post 41 is fixed to the base 10, and the pushing shaft 42 passes through the fixed post 41 to abut against and push the sliding block 31, thereby driving the clamping adjustment assembly 32 to clamp the welding cup and move it toward the cutting workpiece 22 on the slide rail 11. In this way, by pushing the assembly 40, the sliding block 31 moves smoothly on the slide rail 11, which can accurately control the contact between the welding cup and the cutting workpiece 22, thereby ensuring the accuracy and efficiency of the trimming. At the same time, the clamping adjustment assembly 32 can adapt to welding cups of different specifications, improving the flexibility and applicability of the equipment.

[0039] For details, see Figure 2 and Figure 3 The sliding block 31 has a protruding edge at one end that is adapted to the slide rail 11 and is embedded in the slide rail 11, so that it can slide smoothly on the slide rail 11. The other end, that is, the upper end, is provided with a slot 311, and the direction of the slot 311 is perpendicular to the direction of the slide rail 11.

[0040] The clamping adjustment assembly 32 includes a rotating shaft 321, a knob 322, a support base 323, a clamping member 324, a fixing member 325, a spring member 326, and a cover plate 327. The rotating shaft 321 passes through the slot 311 of the sliding block 31, with both ends exposed and connected to the knob 322. The knob 322 can be a round plastic knob 322, or it can be a square knob 322 made of metal.

[0041] The rotating shaft 321 is provided with opposing reverse threads 3211 to facilitate the mounting and movement of the two support seats 323. The support seats 323 are block-shaped and pass through both ends of the rotating shaft 321. When the operator rotates the knob 322, the rotating shaft 321 is driven to rotate. With the action of the reverse threads 3211, the two support seats 323 will move closer or further apart.

[0042] Two fasteners 325 are provided and fixed to the sliding block 31 by bolts. They are used to cover both ends of the slot 311, and through holes 3251 are provided on the fasteners 325 for the rotating shaft 321 to pass through and connect to the knob 322. This can prevent the rotating shaft 321 from shaking during use and enhance its stability.

[0043] The spring element 326 is sleeved on the rotating shaft 321 and located in the slot 311. Its two ends abut against the two support seats 323 respectively. The spring element 326 adopts a helical spring and is used to buffer the two support seats 323 when they move relative to each other, so as to avoid damage to the welding cup due to excessive compression.

[0044] The cover plate 327 is installed on the sliding block 31, located between the two support seats 323 and covering the slot 311. The cover plate 327 can prevent debris from entering the slot 311 and ensure the normal operation of the rotating shaft 321 and the support seat 323.

[0045] For details, see Figure 3 Two clamping components 324 are configured, each mounted opposite to one of the two support seats 323. Each clamping component 324 includes an abutment 3241, a screw 3242, and a clamping plate 3243. One end of the abutment 3241 is integrally connected to the screw 3242, which passes through the support seat 323 and is secured by a nut. The other end of the abutment 3241 is detachably connected to the clamping plate 3243. Multiple clamping plates 3243 are provided on each support seat 323, increasing the contact area with the welding cup and improving clamping stability. When the two support seats 323 move relative to each other, the two clamping components 324 will shift and move closer together, achieving adjustable clamping of the welding cup. This structure can accommodate welding cups of different diameters, enhancing the versatility of the equipment.

[0046] See Figure 2 The fixed post 41 is cylindrical with a threaded end, allowing the operator to securely fix it to the base 10 by screwing. The other end has a hole for the push shaft 42 to pass through. The push shaft 42 is threaded at one end, allowing it to pass through the fixed post 41 and connect to the sliding block 31 via threaded rotation. As the push shaft 42 rotates, it moves forward or backward within the fixed post 41, causing the sliding block 31 to move on the slide rail 11, thereby moving the clamping and adjusting assembly 32 to hold the welding cup towards the cutting workpiece 22. This pushing method allows for precise control of the welding cup's feed rate, ensuring the accuracy of the trimming. Furthermore, to facilitate the rotation of the push shaft, a rotating handle 43 is provided at the end of the push shaft 42 furthest from the sliding block 31, allowing the operator to rotate the push shaft 42. The appearance and structure of the rotating handle 43 are described below. Figure 2 As shown in the image.

[0047] In summary, the welding cup plane trimming device disclosed in this application provides a sliding path and support for the sliding block 31 by setting a slide rail 11 at one end of the base 10, ensuring its stable movement. The motor 21 of the cutting component 20 is set at the other end of the base 10 opposite to the slide rail 11, so that the cutting part 22 is in a suitable position to facilitate the cutting operation of the welding cup. At the same time, the motor 21 provides power to the cutting part 22 to achieve the trimming of the welding cup plane. The sliding block 31 of the clamping mechanism 30 is embedded in the slide rail 11 and can move smoothly along the slide rail 11. The clamping adjustment component 32 is set... At the end of the sliding block 31 away from the base 10, the welding cup can be adjusted to accommodate welding cups of different sizes, ensuring the stability of the welding cup during the trimming process and enhancing the applicability of the equipment to welding cups of different sizes. One end of the fixed column 41 of the pushing component 40 is fixed on the base 10, and the other end is through which the pushing shaft 42 passes. The pushing shaft 42 abuts against and pushes the sliding block 31 to move on the slide rail 11, thereby driving the welding cup held by the clamping adjustment component 32 to move towards the cutting part 22, ensuring that the welding cup is accurately close to the cutting part 22 for plane trimming operation, so as to improve the efficiency and quality of welding cup plane trimming.
