Description

Technical Field

[0001] This utility model relates to the field of ball processing technology, and in particular to a ball punching machine. Background Technology

[0002] In existing ball bearing punching processes, the balls to be punched are typically placed manually into the working area of ​​the punching machine, where the punching mechanism then performs the punching operation. This method has several problems: First, manual feeding is inefficient and cannot meet the needs of large-scale production; second, manual feeding is prone to errors, leading to inaccurate ball positioning or damage; and finally, manual feeding may also pose a safety threat to the operators. Therefore, improving the efficiency and safety of ball bearing punching machines and reducing manual intervention has become an urgent problem to be solved in this field.

[0003] Chinese patent CN216316049U discloses a device for producing round beads, comprising: a water tank, an operating frame inside the water tank, adjusting devices on both sides of the operating frame, a first hydraulic pump inside the operating frame, a first hydraulic rod at the output end of the first hydraulic pump, and a motor housing at one end of the first hydraulic rod. The first motor drives a connecting moving block downwards via a threaded rotating shaft, thereby moving the operating frame into the water inside the water tank. Then, the first hydraulic pump operates, causing it to drive the motor housing downwards via the first hydraulic rod. Simultaneously, a second motor drives a drill bit to rotate via a rotating shaft, thereby drilling holes in the round beads. Drilling the beads while they are submerged in water reduces the temperature generated during drilling, ensuring low-temperature drilling and preventing excessively high temperatures from affecting the drilling quality.

[0004] However, in practical applications, it has been found that the existing technologies mentioned above still have the problem of being unable to automatically feed and unload materials in batches, and their functions are too limited, the equipment is too small, and they are not suitable for large-scale mass production and processing.

[0028] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0029] like Figure 1-2 As shown, this utility model provides a ball punching machine, including a frame 1, characterized in that: it also includes a feeding mechanism 2 installed on the frame 1 and corresponding clamping unit 3 and punching unit 4; the feeding mechanism 2 includes a material pool 21, a top bead unit 22 corresponding to the clamping unit 3 and a baffle unit 24; during punching, the clamping unit 3 and the punching unit 4 work together to form a punching operation area above the material pool 21, the balls to be punched are stored in the material pool 21, the top bead unit 22 lifts a single ball to be punched from the material pool 21 and sends it to the required position, the clamping unit 3 clamps the ball to be punched lifted by the top bead unit 22 and fixes it, the top bead unit 22 returns to the initial position, the baffle unit 24 moves to isolate the material pool 21 from the punching operation area, and the punching unit 4 punches the balls clamped on the clamping unit 3.

[0030] In this embodiment, during punching, the clamping unit 3 and the punching unit 4 work together to form a punching operation area above the material pool 21. The beads to be punched are stored in the material pool 21, which solves the tediousness of manual feeding. During feeding, the top bead unit 22 lifts a single bead to be punched from the many beads in the material pool 21 and sends it to the required position. The clamping unit 3 clamps the bead to be punched lifted by the top bead unit 22 and fixes it. This operation enables the clamping unit 3 to quickly and accurately clamp the bead, resulting in higher work efficiency. Then, the top bead unit 22 returns to the initial position, and at the same time, the baffle unit 24 moves between the clamping unit 3 and the material pool 21 to isolate the material pool 21 from the punching operation area above it, which is used to block the waste and wastewater during the punching operation and prevent them from flowing into the material pool 21. Finally, the punching unit 4 punches the bead clamped by the clamping unit 3. After punching, the punched bead can fall onto the baffle unit 24 for easy collection. This ball punching machine uses the top ball unit 22 and the clamping unit 3 to clamp the balls, making the clamping process faster and more precise, and achieving automatic batch feeding. Then, the baffle unit 24 ensures that the unloading of the balls can also be completed automatically and quickly under normal feeding conditions, without the need for manual labor or other material handling structures, making the equipment structure simpler and the operation more convenient.

[0031] like Figure 2 and Figure 3As shown, the feeding mechanism 2 further includes a support assembly 23 disposed on the material pool 21. The support assembly 23 includes a support plate 231 fixedly mounted on the frame 1 at both ends. The support plate 231 has a first through hole 232 corresponding to the clamping unit 3. A feeding groove 233 is connected to one side of the support plate 231. The feeding groove 233 is located behind the punching unit 3. The support plate 231 is inclined towards the feeding groove 233. The top ball unit 22 passes through the first through hole 232 to transport the ball to the clamping unit 3. The baffle unit 24 includes a baffle 241 disposed parallel to and attached to the support plate 231. The baffle 241 is driven by a push cylinder 242, which is fixedly mounted on the frame 1. In this embodiment, the support assembly 23 is used to support the baffle. In the operation of plate unit 24, a first through hole 232 is opened on the support plate 231 for the passage of the top ball unit 22 during the top ball operation. During feeding, the push cylinder 342 of the baffle unit 24 drives the baffle 241 to move, so that the first through hole 232 is in an open state. The top ball unit 22 lifts a single ball to be punched from among many balls, passes it through the first through hole 232 and sends it to the required position, so that the ball to be punched is clamped and fixed. Then the top ball unit 22 returns to the initial position, and at the same time pushes the push cylinder 342 to drive the baffle 241 to move in the opposite direction, so that the first through hole 232 is in a closed state, separating the material pool from the punching operation area above. During the punching operation, the baffle 241 can block the waste and wastewater during the punching operation so that they can fall into the discharge trough 233. After the punching is completed, the punched ball can also fall back to the baffle 241 so that it can fall into the discharge trough 233 and be collected.

[0032] like Figure 3 As shown, the feeding trough 233 includes an inclined slide plate 2331. Two baffle plates 2332 are respectively provided on both sides of the inclined slide plate 2331 to prevent the balls from falling. One baffle plate 2332 is fixedly connected to the support plate 231, and the other baffle plate 2332 is fixedly installed on the frame 1. A discharge pipe 2333 is provided on the inclined slide plate 2331. In this embodiment, during drilling, waste chips and wastewater flow into the feeding trough 233 and slide down the inclined slide plate 2331, then are discharged through the discharge pipe 2333. After drilling is completed, the drilled balls also fall into the feeding trough 233 and slide down the inclined slide plate 2331, then are discharged through the discharge pipe 2333. Subsequently, it is only necessary to separate the drilled balls from the wastewater and waste chips, making the operation simpler.

[0033] like Figure 2 and Figure 4As shown, the top bead unit 22 includes a top rod 221 that is movably installed through the bottom of the material pool 21. The top end of the top rod 221 is provided with a ball seat 222, and the bottom end of the top rod 221 is provided with a lifting cylinder 223. The lifting cylinder 223 is fixedly installed on the frame 1 and is located below the material pool 21. In this embodiment, when feeding, a single bead to be drilled falls into the ball seat 222 and is held in place. The lifting cylinder 223 drives the top rod 221 to rise, and the top rod 221 lifts the ball seat 222 and the bead to the required position so that the bead is clamped. Then the lifting cylinder 223 drives the top rod 221 back to the initial position, completing one feeding cycle. The structure is simple, the operation is convenient, and the feeding is accurate.

[0034] like Figure 3 As shown, a material guide assembly 211 is provided in the material pool 21 corresponding to the top bead unit 22. The material guide assembly 211 includes a bottom plate 2111 inclined at the bottom of the material pool 21. A second through hole 2112 for the top bead unit 22 to pass through is provided on the bottom plate 2111. A material guide groove 2113 is provided on the bottom plate 2111 corresponding to the second through hole 2112. In this embodiment, a number of round beads to be punched are temporarily stored in the material pool 21. The bottommost round beads roll into the material guide groove 2113 along the inclined bottom plate 2111. At the second through hole 2112, one of the round beads falls onto the top bead unit 22. The top bead unit 22 lifts the round bead and sends it to the required position. After the feeding is completed, the top bead unit 22 returns to the initial position to complete one feeding cycle. The cross-section of the material guide groove 2223 is "V" shaped. The "V" shaped material guide groove 2223 can be used for round beads of different diameters.

[0035] like Figure 4 and Figure 5As shown, the clamping unit 3 includes a clamping assembly 31 for clamping a ball. The clamping assembly 31 includes a first clamping seat 311 and a second clamping seat 312 slidably mounted on the frame 1. A linkage drive assembly 313 is connected between the first clamping seat 311 and the second clamping seat 312. The linkage drive assembly 313 is used to drive the first clamping seat 311 and the second clamping seat 312 to move closer or further away. The linkage drive assembly 313 is fixedly connected to the frame 1. A first chuck 314 is mounted on the first clamping seat 311, and a second chuck 315 is mounted on the second clamping seat 312. The clamping unit 3 is provided with a water pipe clamp 5. In this embodiment, the condensate pipe is clamped by the water pipe clamp 5. Mounted on the clamping unit 3, when the ball to be punched is delivered to the required clamping position, the drive assembly 313 drives the first clamping seat 311 and the second clamping seat 312 to move closer until the first chuck 314 and the second chuck 315 clamp the ball from both sides to complete the clamping action. During the punching process, water pipes are used to pour condensate water to prevent the temperature from getting too high. After the punching is completed, the drive assembly 313 drives the first clamping seat 311 and the second clamping seat 312 to move away, and the first chuck 314 and the second chuck 315 leave the ball. The punched ball falls down, completing the punching operation. Using one drive assembly 313 to drive the first clamping seat 311 and the second clamping seat 312 simultaneously results in a simple structure and stronger synchronization.

[0036] like Figure 5 and Figure 6 As shown, the linkage drive assembly 313 includes a limiting seat 3136 fixedly mounted on the frame 1 and a rotating shaft 3131 passing through the limiting seat 3136. The rotating shaft 3131 is rotatably connected to the limiting seat 3136 via bearings. One end of the rotating shaft 3131 is hinged to a first connecting rod 3132 and a second connecting rod 3133, which are respectively hinged to a first clamping seat 311 and a second clamping seat 312. The other end of the rotating shaft 3131 is fixedly connected to a third connecting rod 3134. The end of 134 is hinged to a clamping electric cylinder 3135, which is fixedly mounted on the frame 1. In this embodiment, the drive assembly 313 consists of a first connecting rod 3132, a second connecting rod 3133, a third connecting rod 3134, and a rotating shaft 3131 to form a linkage transmission structure. The clamping electric cylinder 3135 drives the structure to simultaneously control the movement of the first clamping seat 311 and the second clamping seat 312 to complete the clamping operation. The limiting seat 3136 limits the rotating shaft to the position of the drilling alignment and can realize the synchronous control of the first clamping seat 311 and the second clamping seat 312, making the clamping process more stable.

[0037] like Figure 5 and Figure 6As shown, the clamping unit 3 also includes a flipping drive assembly 32, which includes a rotating gear 321 mounted on the first clamping seat 311 and a transmission rack 322 meshing with the rotating gear 321. A flipping electric cylinder 323 is connected to the transmission rack 322, and the flipping electric cylinder 323 is fixedly mounted on the first clamping seat 311. The flipping drive assembly 32 also includes a transmission assembly 324 disposed between the first chuck 314 and the second chuck 315. The first chuck 314 and the second chuck 315 are respectively connected to the first clamping seat 311. 11 and the second clamp 312 are rotatably connected, and the first clamp 314 is connected to the rotating gear 321; the transmission assembly 324 includes a connecting rod 3241 connected to the first clamp 314 and a receiving sleeve 3242 connected to the first clamp 314, the connecting rod 3241 and the receiving sleeve 3242 are sleeved together; the first clamp 311 is provided with a limiting post 325, and the transmission rack 322 is located between the limiting post 325 and the rotating gear 321; in this embodiment, during the drilling process of the ball, because the diameter of the hole to be drilled is very small... Therefore, a relatively fine drill bit is required, which makes it prone to damage during drilling. Drilling too deep also prevents proper chip removal, affecting the drilling effect. Therefore, a flipping drive assembly 32 is designed. When the ball hole is halfway drilled, the drill bit is removed, and the flipping assembly 32 flips the ball before drilling again. After two operations, a through hole is formed. This facilitates chip removal, effectively extends the drill bit's lifespan, and improves drilling quality. The connecting rod 3241 and the receiving sleeve 3242 are simultaneously engaged when the ball is clamped, allowing the first chuck 314 to connect with the second chuck... The head 315 rotates synchronously to complete the flipping action of the ball. During the flipping, the limit post 325 presses down on the transmission rack 322 to ensure that the transmission rack 322 and the rotating gear 321 are tightly meshed, thus ensuring the stability of the flipping action. The flipping electric cylinder 323 drives the transmission rack 322 to drive the rotating gear 321 to rotate, thereby driving the first chuck 314 and the second chuck 315 to rotate synchronously through the transmission assembly 324. The detachable design makes it easy to clamp balls of different specifications and realize the flipping action of the ball. The synchronous rotation is easy to control and can also ensure that the ball will not fall off during the flipping process.

[0038] like Figure 4 , Figure 7 and Figure 8As shown, the drilling unit 4 includes a guide rail 41 mounted on the frame 1. A lifting seat 42 and a floating seat 43 are slidably mounted on the guide rail 41. A driving lifting mechanism 421 for driving the drilling unit 4 to rise and fall is connected to the lifting seat 42. The driving lifting mechanism 421 is fixedly mounted on the frame 1. A drilling drill bit 44 and a protective sleeve assembly 45 for protecting the drilling drill bit 44 are connected and mounted on the floating seat 43. A drilling motor 441 is connected to the drilling drill bit 44 and is fixedly mounted on the floating seat 43. A detection assembly 46 for detecting drilling positioning is also provided between the lifting seat 42 and the floating seat 43. The detection component 46 includes a displacement sensor 461 installed between the lifting seat 42 and the floating seat 43, and a limiting member 462 connected to the floating seat 43. The limiting member 462 is movably inserted through the lifting seat 42, and the limiting head of the limiting member 462 is located outside the lifting seat 42 to prevent the limiting member 462 from falling out of the lifting seat 42. The drilling unit 4 also includes a counterweight 47. In this embodiment, the drilling drill bit 44 is inserted into the sheath assembly 45. The drilling drill bit 44 is connected and fixed to the drilling motor 441 by a screw head. The driving lifting mechanism 421 drives the lifting seat 42 to move the drilling unit 4 up and down to perform the operation. During drilling, the drilling positioning is first performed on the ball surface. 45 is pushed out, and the lifting seat 42 drives the drilling bit 44 to descend, drilling and positioning on the surface of the ball. At this time, the protective sleeve assembly protects the stability of the drilling bit 44 during positioning, preventing it from bending and breaking. After positioning and drilling are completed, the protective sleeve assembly 5 rises, and the drilling bit 44 continues to complete the drilling work under the drive of the drilling motor 441. During the above operation, the limiting member 462 of the detection component 46 utilizes the characteristics of its limiting screw. The lower end is fixedly connected to the floating seat, and the upper part is movably inserted on the lifting seat 42. The upper end with the screw head is used to limit and suspend the floating seat 43 below to prevent it from falling off, and to leave a certain distance between the lifting seat 42 and the floating seat 43 for drilling positioning and drilling. The lifting seat 42 drives the entire drilling unit to descend. When the end of the drilling bit 44 contacts the surface of the ball, the lifting seat 42 continues to descend. The ball exerts a force on the end of the drilling bit 44, causing the floating seat 43 to float up. The distance reserved between the lifting seat 42 and the floating seat 43 will shorten. At this time, the displacement sensor 461 senses the above-mentioned distance change and obtains feedback information that the drilling bit 44 is in contact with the ball. Then the drilling motor 441 starts to work and drives the drilling bit 44 to start drilling positioning or drilling operation to ensure the accuracy of drilling operation. The counterweight 47 is used selectively and, together with the weight of the floating part of the drilling unit 4, facilitates drilling operations on balls of different specifications.

[0039] like Figure 7 and Figure 9As shown, the sheath assembly 45 includes a mounting plate 451. A limiting drive cylinder 452 for driving the movement of the sheath assembly 45 is connected to the mounting plate 451. The limiting drive cylinder 452 is fixedly mounted on the floating seat 43. A limiting plate 453 is connected below the mounting plate 451. A third through hole 454 and a limiting hole 455 are respectively opened on the mounting plate 451 and the limiting plate 453 corresponding to the drilling bit 44. A limiting bearing 456 is provided in the limiting hole 455. A sheath 457 is provided on the inner side wall of the limiting bearing 456. A pressure block 458 for pressing the limiting bearing 456 is provided on the limiting hole 455. In this embodiment, when the drilling unit 4 descends, the limiting drive cylinder 452 is controlled to drive the limiting plate 454 to push out. The drilling bit 44 passes through the limiting hole 455 and is protected, preventing the head of the drilling bit 44 from deviating when it contacts and positions the ball, so as to ensure the drilling of the ball. The hole is precisely positioned, and then the limit drive cylinder 452 is controlled to drive the limit plate 454 to slightly lift, setting it a certain distance from the surface of the ball to facilitate chip removal during drilling. The drilling drill 44 is then activated to drill the positioning hole. After drilling the positioning hole, the limit drive cylinder 452 is controlled to drive the limit plate 454 back to the initial position to continue the drilling operation. Since the drilling drill 44 will wear during the drilling process, a positioning operation is required before each drilling operation. Therefore, the limit drive cylinder 452 is designed to control the change of the limit position of the limit plate 454 to cope with the wear of the drilling drill 44 and make the drilling more accurate. A protective sleeve 457 is set to contact the drilling drill 44, which not only protects the drilling drill 44 but also connects the drilling drill 44 and the limit bearing 456 to prevent friction and wear between the limit bearing 456 and the drilling drill 44 during rotation. The pressure block 458 presses down on the limit bearing 456 to prevent the bearing from falling out.

[0040] All technical features in this embodiment can be modified in appearance according to actual needs.
