Description

Technical Field

[0001] This utility model relates to the field of ball punching technology, and in particular to a clamping and flipping device for 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 when drilling a ball, because the hole diameter is very small, a finer drill bit is required. This makes the drill bit prone to damage during the drilling process, and drilling too deep will prevent the waste chips from being discharged properly, thus affecting the drilling effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a clamping and flipping device for a ball punching machine. The clamping component has a simple structure and good clamping stability. Furthermore, a flipping component is added to the clamping design, which effectively solves the problem that drilling too deep can easily damage the drill bit.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A clamping and flipping device for a ball punching machine includes a clamping assembly mounted on the frame of the ball punching machine for clamping and fixing balls. The clamping assembly includes a first clamp and a second clamp slidably mounted on the frame. A linkage drive assembly is connected between the first clamp and the second clamp, which drives the first clamp and the second clamp to move closer or further away. The linkage drive assembly is fixedly connected to the frame. A first chuck is mounted on the first clamp, and a second chuck is mounted on the second clamp. During operation, the first chuck and the second chuck move closer to each other to clamp and fix the balls. The device also includes a flipping drive assembly for driving the first chuck and the second chuck to flip.

[0008] Furthermore, the linkage drive assembly includes a limiting seat fixedly mounted on the frame and a rotating shaft passing through the limiting seat. The rotating shaft is rotatably connected to the limiting seat via bearings. One end of the rotating shaft is hinged to a first connecting rod and a second connecting rod, which are respectively hinged to a first clamping seat and a second clamping seat. The other end of the rotating shaft is fixedly connected to a third connecting rod, and the end of the third connecting rod is hinged to a clamping electric cylinder, which is fixedly mounted on the frame.

[0009] Furthermore, the flipping drive assembly includes a rotating gear for driving the first chuck and the second chuck to rotate and a transmission rack meshing with the rotating gear. A flipping electric cylinder is connected to the transmission rack and is fixedly installed on the first chuck.

[0010] Furthermore, the rotating gear is rotatably mounted on the first clamp, and the flipping drive assembly also includes a transmission assembly disposed between the first clamp and the second clamp. The first clamp and the second clamp are rotatably connected to the first clamp and the second clamp, respectively, and the first clamp is connected to the rotating gear.

[0011] Furthermore, the transmission assembly includes a connecting rod connected to the first clamp and a receiving sleeve connected to the second clamp, wherein the connecting rod is sleeved with the receiving sleeve.

[0012] Furthermore, the first clamp is provided with a limiting post, and the transmission rack is located between the limiting post and the rotating gear.

[0013] Furthermore, the clamping assembly is equipped with a water pipe clamp.

[0014] The beneficial effects of this utility model are:

[0015] In practical applications, during operation, when the ball to be drilled is fed to the required clamping position, the drive assembly drives the first and second clamps to move closer until the first and second clamps clamp the ball from both sides, completing the action of gripping and fixing the ball. During the drilling process, after one side of the ball is drilled, the drill bit is relatively fine due to the small hole diameter. This makes the drill bit prone to damage during drilling, and drilling too deep can prevent the proper removal of debris, affecting the drilling effect. Therefore, a flipping drive assembly is designed to move the ball when the hole is halfway drilled. After the drill bit is ejected, the ball is flipped using a flipping component and drilled again. This two-stage process creates a through hole, facilitating chip removal, extending the drill bit's lifespan, and improving drilling quality. The flipping drive component simultaneously rotates the first and second chucks, flipping the held ball before drilling continues. After drilling, the drive component moves the first and second chucks away from the ball, allowing it to fall and completing the drilling operation. Using a single drive component to simultaneously drive the first and second chucks results in a simple structure and enhanced synchronization. This invention features a simple clamping component with stable clamping performance. Furthermore, the addition of a flipping component effectively solves the problem of drill bit damage caused by excessive drilling depth. Attached Figure Description

[0018] 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.

[0019] like Figure 1-2As shown, this utility model provides a clamping and flipping device for a ball punching machine, including a clamping assembly 31 for clamping and fixing balls, mounted on the frame 1 of the ball punching machine. The clamping assembly 31 includes a first clamping seat 311 and a second clamping seat 312 slidably mounted on the frame 1. A connecting rod drive assembly 313 is connected between the first clamping seat 311 and the second clamping seat 312. The connecting rod 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 connecting rod 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. During operation, the first chuck 314 and the second chuck 315 move closer to each other to clamp and fix the balls. The device also includes a flipping drive assembly 32 for driving the first chuck 314 and the second chuck 315 to flip.

[0020] In this embodiment, during operation, when the ball to be drilled is delivered to the required clamping position, the linkage drive assembly 313 drives the first clamp 311 and the second clamp 312 to move closer until the first chuck 314 and the second chuck 315 clamp the ball from both sides, completing the action of clamping and fixing the ball. During the drilling process, after one side of the ball is drilled, the drill bit is relatively small due to the small hole diameter, making it prone to damage. Drilling too deep can also prevent the proper removal of debris, affecting the drilling effect. Therefore, a flipping drive assembly 32 is designed to remove the drill bit when the ball hole is halfway drilled, utilizing the flipping drive assembly 32. 2. After flipping the ball, drilling is performed again. Two operations create a through hole, facilitating chip removal and effectively extending the drill bit's lifespan while improving drilling quality. The flipping drive assembly 32 drives the first chuck 314 and the second chuck 315 to rotate simultaneously, causing the held ball to flip and continue drilling. After drilling is complete, the connecting rod drive assembly 313 drives the first chuck 311 and the second chuck 312 to move away, causing the first chuck 314 and the second chuck 315 to leave the ball, and the drilled ball falls down, completing the drilling operation. Using a single connecting rod drive assembly 313 to simultaneously drive the first chuck 311 and the second chuck 312 results in a simple structure and stronger synchronization. The device's clamping assembly has a simple structure and good clamping stability. Furthermore, the addition of a flipping component effectively solves the problem of drill bit damage caused by excessive drilling depth.

[0021] like Figure 1As 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 which is hinged to... A clamping electric cylinder 3135 is provided, which is fixedly installed 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 linkage transmission structure to form the linkage drive assembly 313, which simultaneously controls the first clamping seat 311 and the second clamping seat 312 to complete the clamping operation of the ball. 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.

[0022] like Figure 1 As shown, the flipping drive assembly 32 includes a rotating gear 321 for driving the first chuck 314 and the second chuck 315 to rotate, 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 installed on the first clamping seat 311. In this embodiment, 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 through the transmission assembly 324, realizing the flipping action of the ball.

[0023] like Figure 1 As shown, the rotating gear 321 is rotatably mounted on the first clamp 311. The flipping drive assembly 32 further includes a transmission assembly 324 disposed between the first clamp 314 and the second clamp 315. The first clamp 314 and the second clamp 315 are rotatably connected to the first clamp 311 and the second clamp 312, respectively. The first clamp 314 is connected to the rotating gear 321. In this embodiment, the flipping electric cylinder 323 drives the transmission rack 322 to drive the rotating gear 321 to rotate, thereby driving the first clamp 314 and the second clamp 315 to rotate synchronously through the transmission assembly 324. The detachable design facilitates clamping balls of different sizes and realizes the flipping action of the balls. The transmission assembly 324 assists in realizing synchronous rotation, which is easy to control and can also ensure that the balls will not fall off during the flipping process.

[0024] like Figure 1As shown, the transmission assembly 324 includes a connecting rod 3241 connected to the first clamp 315 and a receiving sleeve 3242 connected to the first clamp 316. The connecting rod 3241 and the receiving sleeve 3242 are sleeved together. In this embodiment, the connecting rod 3241 and the receiving sleeve 3242 are sleeved together synchronously when the ball is clamped. After the connection, the first clamp 315 and the second clamp 316 can rotate synchronously to complete the flipping action of the ball.

[0025] like Figure 1 As shown, 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, when flipping the dough, the limiting post 325 is used to press down 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.

[0026] like Figure 1 As shown, the clamping assembly 31 is provided with a water pipe clamp 5; in this embodiment, the condensate pipe is clamped and installed on the clamping assembly 31 by the water pipe clamp 5. During the drilling process, the water pipe is filled with condensate water to prevent the temperature from getting too high during drilling.

[0027] All technical features in this embodiment can be modified in appearance according to actual needs.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
