Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing and processing technology, specifically a tooling for batch processing of conductive connecting plates using integrated milling and drilling. Background Technology

[0002] Mass production of parts must ensure processing efficiency. Without increasing the number of processing equipment, the processing efficiency of a single machine must be guaranteed. The processing steps of a single part must include auxiliary steps such as clamping and positioning. Only by shortening the time of auxiliary steps can the processing efficiency of a single machine be improved.

[0003] Conductive connection plates are a type of component in lithium battery copper foil equipment. Due to the large-volume production, each set of lithium battery copper foil equipment contains 16 conductive connection plates, and each batch of lithium battery copper foil equipment typically consists of 12 or 24 units. The product delivery cycle is approximately 3 months, which necessitates that the processing efficiency of the conductive connection plates meet the product manufacturing requirements.

[0004] The conventional machining method involves processing individual parts on a CNC machining center. The main machining processes are milling, drilling, tapping, and chamfering. However, each part requires nearly 30 minutes for clamping, positioning, and finding the reference point. The actual cutting time for a single part is approximately four hours. Therefore, clamping and positioning account for nearly 12% of the time, which greatly restricts the machining efficiency. To address this issue, a tooling for batch processing conductive connection plates that integrates milling and drilling is needed to solve the above technical problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tooling for batch processing of conductive connecting plates by integrating milling and drilling.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tooling for batch processing of conductive connecting plates by milling and drilling, comprising a base, wherein a positioning and clamping mechanism is provided on the top of the base;

[0007] The positioning and clamping mechanism includes several sets of inclined wedge clamps on the top of the base. Each set of inclined wedge clamps consists of two symmetrically arranged clamping plates. An inclined surface is provided on the side of the two clamping plates that are close to each other. A workpiece to be processed is provided between the two clamping plates. A T-shaped round hole is provided at the top of each workpiece. Several through holes are provided at the top of the base. Several L-shaped plates are fixed to the bottom of the base. A pneumatic controller is fixed to the top of the horizontal end of each L-shaped plate. A threaded groove is provided at the top of each pneumatic controller. Hexagon socket screws are provided in both the T-shaped round holes and the through holes, and the hexagon socket screws are threadedly connected to the threaded grooves.

[0008] Preferably, the clamping plate is composed of wedge clamping plates, L-shaped plates, sliding plates, sliding holes, slots, limiting plates, and locking plates. Each of the two wedge clamping plates has an L-shaped plate on its opposite side, and the bottom end of each L-shaped plate is fixedly connected to the top end of the base. Each of the two wedge clamping plates has a sliding plate fixedly connected to its bottom end on its opposite side, and the ends of the sliding plates are located within the L-shaped plates. Each L-shaped plate has a sliding hole at its top horizontal end, and a slot is formed on the front side of each sliding hole. Each sliding plate has a limiting plate fixedly connected to its top end, and each limiting plate has a locking plate hinged to its top end, with the locking plates located within the slots.

[0009] Preferably, a limiting block is fixed to one side of each of the two L-shaped plates where their vertical ends are close together, and the limiting blocks are located outside the sliding hole.

[0010] Preferably, T-shaped slide rails are provided on the side of the two wedge clamps that are close to each other, and T-shaped sliders are fixed to both sides of the workpiece to be processed.

[0011] Preferably, the diameter of the bottom end of the hexagon socket screw is smaller than the diameter of the through hole, and the diameter of the top end of the hexagon socket screw is larger than the diameter of the top end of the T-shaped hole.

[0012] Preferably, a set of springs is fixedly connected to one side of the L-shaped plate near the slide plate, and the other end of each spring is fixedly connected to the slide plate.

[0013] Preferably, the bottom ends of both the front and rear sides of the wedge clamp are fixedly connected to side plates, and a set of rollers are rotatably connected to the side of the two side plates that are close to each other.

[0014] Beneficial effects:

[0015] Compared with existing technologies, this integrated milling and drilling tooling for batch processing of conductive connection plates has the following advantages:

[0016] I. This invention involves installing and fixing a wedge-shaped clamp in a corresponding position, placing the workpiece between the wedge-shaped clamp (two clamping plates), and then inserting an internal hexagonal screw into a T-shaped hole. The bottom end of the internal hexagonal screw passes through a through hole and connects to a threaded groove. A pneumatic controller pulls the internal hexagonal screw downwards, causing it to pull the workpiece downwards through the T-shaped hole. As the workpiece moves downwards, the friction between the workpiece and the two clamping plates increases, and the clamping force gradually increases. After the workpiece is assembled onto the base, it is processed in batches using an integrated program. The workpiece is used as the processing reference, and the upper surface is processed in batches using a CNC machining center. Drilling and tapping processes can also be performed, achieving mass production and greatly improving processing efficiency.

[0017] Second, by pushing the card plate upwards, the present invention disengages it from the card slot, allowing the wedge clamp to move and the pressure on the workpiece to be processed to disappear, thus facilitating the removal of the workpiece and avoiding damage to the workpiece when forcibly removed.

[0026] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0027] like Figures 1 to 7 As shown, a milling and drilling integrated batch processing fixture for conductive connection plates includes a base 1. The processing dimensions of each position of the base 1 are determined according to the length and width dimensions of the workpiece 23 to be processed. A positioning and clamping mechanism 2 is provided on the top of the base 1.

[0028] The positioning and clamping mechanism 2 includes several sets of inclined wedge clamps 20 on the top of the base 1. Each set of inclined wedge clamps 20 consists of two symmetrically arranged clamping plates 21. An inclined surface 22 is provided on the side of the two clamping plates 21 that are close to each other. A workpiece 23 to be processed is provided between the two clamping plates 21. A T-shaped round hole 24 is provided at the top of each workpiece 23. Several through holes 25 are provided at the top of the base 1. Several L-shaped plates 26 are fixed to the bottom of the base 1. A pneumatic controller 27 is fixed to the top of the horizontal end of each L-shaped plate 26. A threaded groove 28 is provided at the top of each pneumatic controller 27. A hexagon socket screw 29 is provided in both the T-shaped round hole 24 and the through hole 25. The hexagon socket screw 29 is threadedly connected to the threaded groove 28. The diameter of the bottom end of the hex socket screw 29 is smaller than the diameter of the through hole 25, and the diameter of the top end of the hex socket screw 29 is larger than the diameter of the top end of the T-shaped round hole 24, so that the hex socket screw 29 will only connect with the threaded groove 28, making it convenient to pull down the workpiece 23 to be processed.

[0029] During operation, the machining dimensions of each position on the base 1 are determined according to the length and width dimensions of the workpiece 23. Then, the inclined wedge clamps 20 are installed and fixed in the corresponding positions. The number of inclined wedge clamps 20 can be increased or decreased according to the dimensions of the workpiece 23. The dimensions of the inclined wedge clamps 20 need to match the dimensions of the workpiece 23. The workpiece 23 is placed in the inclined wedge clamps 20, that is, between the two clamping plates 21. Then, the socket head cap screws 29 are inserted into the T-shaped round holes 24. The diameter of the top of the T-shaped round holes 24 is smaller than the diameter of the top of the socket head cap screws 29. The bottom end of the socket head cap screws 29 passes through the through holes 25 and screws... The groove 28 is connected, and then the pneumatic controller 27 is controlled. The pneumatic controller 27 pulls down the hexagon socket screw 29. The hexagon socket screw 29 pulls down the workpiece 23 through the T-shaped hole 24. As the workpiece 23 moves down, the friction between the workpiece 23 and the two clamping plates 21 increases, and the clamping force gradually increases. After the workpiece 23 is assembled onto the base 1, it is batch processed by programming an integrated program. The workpiece 23 is used as the processing reference, and the upper surface is batch processed by CNC machining center. Drilling and tapping processes can also be performed to achieve mass production and greatly improve processing efficiency.

[0030] The clamping plate component 21 consists of wedge-shaped clamping plates 211, L-shaped plates 212, sliding plates 213, sliding holes 214, slots 215, limiting plates 216, and clamping plates 217. Each of the two wedge-shaped clamping plates 211 has an L-shaped plate 212 on its far side, and the bottom end of each L-shaped plate 212 is fixedly connected to the top end of the base 1. Side plates 7 are fixedly connected to the bottom ends of both the front and rear sides of the wedge-shaped clamping plates 211. A set of rollers 8 is rotatably connected to the side of each of the two side plates 7 that are close to each other. The design of the rollers 8 reduces the friction between the wedge-shaped clamping plates 211 and the base 1. Sliding plates 213 are fixedly connected to the bottom ends of the two wedge-shaped clamping plates 211 on their far sides, and the ends of the sliding plates 213 are located within the L-shaped plates 212. Sliding holes 214 are provided at the top of the horizontal ends of each L-shaped plate 212. Limiting blocks 3 are fixed to the sides of the two L-shaped plates 212 that are close to each other on the vertical ends, and the limiting blocks 3 are located outside the sliding holes 214. A slot 215 is provided on the front side of each sliding hole 214. A limiting plate 216 is fixed to the top of each sliding plate 213. The limiting plate 216 passes through the sliding hole 214 and is slidably connected to it. A locking plate 217 is hinged to the top of each limiting plate 216, and the locking plate 217 is located within the slot 215. The limiting blocks 3 can restrict the limiting plates 216 from sliding out of the sliding holes 214, ensuring that the range of motion of the sliding holes 214 is limited within the sliding holes 214. The design of the limiting blocks 3 can prevent the sliding plate 213 from separating from the L-shaped plates 212. T-shaped slide rails 4 are provided on the side of the two wedge-shaped clamps 211 that are close to each other. T-shaped sliders 5 are fixed to both sides of the workpiece 23. The design of the T-shaped slide rails 4 and T-shaped sliders 5 plays a positioning role in installing the workpiece 23 and aligns the T-shaped round hole 24 and the through hole 25. A set of springs 6 are fixed to the side of the L-shaped plate 212 that is close to the slide plate 213, and the other end of the springs 6 is fixed to the slide plate 213. The design of the springs 6 is that when the workpiece 23 is removed, the two wedge-shaped clamps 211 will move closer to each other under the action of the T-shaped slide rails 4 and T-shaped sliders 5. This facilitates the automatic return of the two wedge-shaped clamps 211 under the action of the springs 6 after removal, making it easy for the clamping plate 217 to align with the slot 215.

[0031] During operation, since the two clamping plates 21 are fixed, the workpiece 23 is squeezed between the two wedge clamping plates 211. When it is necessary to remove it, it is difficult to remove the workpiece 23 due to the large squeezing force. At this time, the clamping plate 217 is pushed upward to disengage it from the slot 215, and the wedge clamping plate 211 can move. The squeezing force on the workpiece 23 disappears, and the workpiece 23 can be directly removed upward. This makes it easy to remove the workpiece 23 and avoids forcibly removing it, which may damage the workpiece 23.

[0032] Working principle: The machining dimensions of each position on the base 1 are determined based on the length and width dimensions of the workpiece 23. Then, the inclined wedge clamps 20 are installed and fixed in the corresponding positions. The number of inclined wedge clamps 20 can be increased or decreased according to the dimensions of the workpiece 23. The dimensions of the inclined wedge clamps 20 must match the dimensions of the workpiece 23. The workpiece 23 is placed in the inclined wedge clamps 20, that is, between the two clamping plates 21. Then, the socket head cap screws 29 are inserted into the T-shaped round hole 24. The diameter of the top of the T-shaped round hole 24 is smaller than the diameter of the top of the socket head cap screw 29. The bottom end of the socket head cap screw 29 passes through the through hole 25 and engages with the screw... The groove 28 is connected, and then the pneumatic controller 27 is controlled. The pneumatic controller 27 pulls down the hexagon socket screw 29. The hexagon socket screw 29 pulls down the workpiece 23 through the T-shaped hole 24. As the workpiece 23 moves down, the friction between the workpiece 23 and the two clamping plates 21 increases, and the clamping force gradually increases. After the workpiece 23 is assembled onto the base 1, it is batch processed by programming an integrated program. The workpiece 23 is used as the processing reference, and the upper surface is batch processed by CNC machining center. Drilling and tapping processes can also be performed to achieve mass production and greatly improve processing efficiency.

[0033] Since the two clamping plates 21 are fixed, the workpiece 23 is squeezed between the two wedge clamping plates 211. When it needs to be removed, it is difficult to remove the workpiece 23 due to the large squeezing force. At this time, the clamping plate 217 is pushed upward to disengage it from the slot 215, and the wedge clamping plate 211 can move. The squeezing force on the workpiece 23 disappears, making it easier to remove the workpiece 23. This avoids forcibly removing the workpiece 23 and causing damage to it.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
