Description

Technical Field

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

[0002] In existing ball bearing drilling processes, the balls to be drilled are typically placed manually into the working area of ​​the drilling machine, and then the drilling mechanism performs the drilling 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, during the drilling process, drill bit wear can cause inaccurate positioning, making it impossible to complete the drilling. Therefore, how to improve the working efficiency and safety of ball bearing drilling machines and reduce manual intervention has become an urgent problem to be solved in this field.

[0003] For example, Chinese patent CN216935126U discloses a device for producing round beads, including a water tank. An operating frame is located inside the water tank, with adjusting devices on both sides of the operating frame. A first hydraulic pump is located inside the operating frame, and a first hydraulic rod is located at the output end of the first hydraulic pump. A motor housing is located at one end of the first hydraulic rod. The first motor drives a connecting moving block downwards via a threaded rotating shaft, causing the connecting moving block to move 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 underwater reduces the temperature generated during drilling, ensuring low-temperature drilling and preventing excessively high temperatures from affecting the drilling quality. This technical solution only improves drilling quality by avoiding excessively high drilling temperatures; its function is limited, and its effect is generally mediocre.

[0004] In practical applications, it has been found that existing technologies often involve directly drilling with a drill bit without a positioning action. This can easily cause the drill bit to shift sideways when it first contacts the surface of the ball, affecting the accuracy of the drilling position. Furthermore, this direct operation can easily break the drill bit. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a floating drilling device for a ball bearing drilling machine. The device uses a lifting seat and a floating seat in conjunction with a detection component to form a positioning auxiliary mechanism to help the drilling drill bit accurately position itself during the drilling process, ensuring the accuracy of the drilling position. At the same time, a protective sleeve component is designed to protect the drilling drill bit, ensuring the smooth drilling process and effectively reducing the wear and tear of the drilling drill bit.

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

[0007] A floating drilling device for a ball bearing punch includes a drilling unit mounted on the frame of the ball bearing punch; the drilling unit includes a guide rail mounted on the frame, a lifting seat and a floating seat slidably mounted on the guide rail, a drilling bit and a protective sleeve assembly for protecting the drilling bit are connected and mounted on the floating seat, and a detection component for detecting drilling positioning is also provided between the lifting seat and the floating seat.

[0008] Furthermore, the lifting base is connected to a drive lifting mechanism for driving the drilling unit to rise and fall, and the drive lifting mechanism is fixedly installed on the frame.

[0009] Furthermore, a drilling motor is connected to the drilling bit, and the drilling motor is fixedly mounted on the floating base.

[0010] Furthermore, the detection component includes a displacement sensor installed between the lifting seat and the floating seat, and also includes a limiting member connected to the floating seat. The limiting member is movably inserted through the lifting seat, and the limiting head of the limiting member is located outside the lifting seat to prevent the limiting member from detaching from the lifting seat.

[0011] Furthermore, the sheath assembly includes a mounting plate, on which a limit drive electric cylinder for driving the movement of the sheath assembly is connected. The limit drive electric cylinder is fixedly mounted on the floating seat. A limit plate is connected below the mounting plate. The mounting plate and the limit plate are respectively provided with a third through hole and a limit hole corresponding to the drilling bit. A limit bearing is provided in the limit hole.

[0012] Furthermore, the inner wall of the limiting bearing is provided with a protective sleeve.

[0013] Furthermore, the limiting hole is provided with a pressure block for pressing down the limiting bearing.

[0014] Furthermore, the punching unit also includes a counterweight.

[0015] The beneficial effects of this utility model are:

[0016] In practical applications, the drill bit is inserted into the sheath assembly. A positioning auxiliary mechanism, consisting of a lifting seat and a floating seat, along with a detection component, assists the drill bit in accurately positioning itself during drilling, ensuring precise drilling accuracy. During drilling, the lifting seat moves the drilling unit up and down. Initially, drilling is positioned on the ball surface. The sheath assembly extends to contact the ball surface, and the lifting seat lowers the drill bit, allowing its tip to pass through the sliding sleeve assembly and contact the ball surface. The drill bit then initiates drilling positioning on the ball surface. At this point, the sheath... The component protects the drill bit during positioning, preventing it from bending or breaking. After positioning and drilling, the sheath assembly rises, and the drill bit continues drilling. During this operation, when the end of the drill bit contacts the surface of the ball, the lifting seat continues to descend, and the ball exerts a force on the end of the drill bit, causing the floating seat to rise. The distance between the lifting seat and the floating seat changes. The detection component senses this change in distance and receives feedback that the drill bit is in contact with the ball. The drill bit then begins drilling positioning or drilling operations, ensuring the accuracy of the drilling operation. This invention utilizes the lifting seat and floating seat, along with the detection component, to form a positioning auxiliary mechanism that assists the drill bit in accurately positioning the drilling position during drilling, ensuring accurate drilling. Simultaneously, the sheath assembly protects the drill bit, ensuring a smooth drilling process and effectively reducing drill bit wear. Attached Figure Description

[0021] 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.

[0022] like Figure 1-2As shown, this utility model provides a floating drilling device for a ball bearing punch, including a drilling unit 4 installed on the frame 1 of the ball bearing punch; the drilling unit 4 includes a guide rail 41 installed on the frame 1, a lifting seat 42 and a floating seat 43 slidably installed on the guide rail 41, a drilling drill bit 44 and a protective sleeve assembly 45 for protecting the drilling drill bit 44 are connected and installed on the floating seat 43, and a detection assembly 46 for detecting drilling positioning is also provided between the lifting seat 42 and the floating seat 43.

[0023] In this embodiment, the drilling bit 44 passes through the sheath assembly 45. A positioning auxiliary mechanism, consisting of a lifting seat 42 and a floating seat 43 in conjunction with a detection component 46, assists the drilling bit 44 in accurately positioning the drilling position during the drilling process, ensuring accurate drilling accuracy. During drilling, the lifting seat 42 drives the drilling unit 4 to rise and fall. First, drilling positioning is performed on the surface of the ball. The sheath assembly 45 extends out to contact the surface of the ball, and the lifting seat 42 drives the drilling bit 44 to descend, allowing the front end of the drilling bit 44 to pass through the sliding sleeve assembly 45 and contact the surface of the ball. The drilling bit 44 is then activated to perform drilling positioning on the surface of the ball. At this time, the sheath assembly... The protective sleeve assembly 5 protects the drill bit 44 during positioning, preventing it from bending or breaking. After positioning and drilling are completed, the protective sleeve assembly 5 rises, and the drill bit 44 continues drilling. During the above operation, when the end of the drill bit 44 contacts the surface of the ball, the lifting seat 42 continues to descend, and the ball exerts a force on the end of the drill bit 44, causing the floating seat 43 to float upwards. The distance between the lifting seat 42 and the floating seat 43 changes. At this time, the detection assembly 46 senses the change in distance and receives feedback that the drill bit 44 is in contact with the ball. Then, the drill bit 44 begins drilling positioning or drilling operation, ensuring the accuracy of the drilling operation. This device uses the lifting seat 42 and the floating seat 43 in conjunction with the detection assembly 46 to form a positioning auxiliary mechanism to assist the drill bit 44 in accurately positioning the drilling position during the drilling process, ensuring the accuracy of the drilling position. At the same time, the protective sleeve assembly 45 is designed to protect the drill bit 44, ensuring the smooth drilling process and effectively reducing the wear of the drill bit.

[0024] like Figure 2 As shown, the lifting seat 42 is connected to a driving lifting mechanism 421 for driving the drilling unit 4 to rise and fall. The driving lifting mechanism 421 is fixedly installed on the frame 1. In this embodiment, the drilling drill bit 44 is connected and fixed to the drilling motor 441 through a screw head. The driving lifting mechanism 421 drives the lifting seat 42 to drive the drilling unit 4 to rise and fall to perform the operation.

[0025] Figure 2As shown, a drilling motor 441 is connected to the drilling bit 44, and the drilling motor 441 is fixedly installed on the floating seat 43; in this embodiment, the drilling motor 441 drives the drilling bit 44 to perform drilling operations.

[0026] like Figure 2 and Figure 3 As shown, 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. In this embodiment, the limiting member 462 of the detection component 46 utilizes the characteristics of its limiting screw, with its lower end fixedly connected to the floating seat, and its upper part movably inserted through the lifting seat 42. The upper end with the screw head is used to limit and suspend the floating seat 43 below, preventing it from falling out, and making the lifting seat 42... A certain distance is reserved between the lifting seat 42 and the floating seat 43. During 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 ball will exert a force on the end of the drilling bit 44 as the lifting seat 42 continues to descend, causing the floating seat 43 to float up as a whole. The reserved distance 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 the information feedback 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.

[0027] like Figure 2 and Figure 4As 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. In this embodiment, when the drilling unit 4 descends, the limiting drive cylinder 452 is controlled to drive the limiting plate 454 to extend, and the drilling bit 44 passes through the limiting hole 455 and is protected. To prevent the drill bit 44 from deviating when it contacts and positions the ball, ensuring accurate positioning of the ball during drilling, the limit drive cylinder 452 is controlled to slightly raise the limit plate 454, placing it a certain distance from the ball surface to facilitate chip removal during drilling. The drill bit 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 its initial position to continue drilling. Since the drill bit 44 will wear during drilling, 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 drill bit 44, making drilling more accurate.

[0028] like Figure 4 As shown, the inner wall of the limiting bearing 456 is provided with a protective sleeve 457. In this embodiment, the protective sleeve 457 is provided to contact the drilling bit 44, which not only protects the drilling bit 44, but also connects the drilling bit 44 and the limiting bearing 456, thus preventing friction and wear between the two during the rotation of the limiting bearing 456 with the drilling bit 44.

[0029] like Figure 4 As shown, the limiting hole 455 is provided with a pressing block 458 for pressing the limiting bearing 456; in this embodiment, the pressing block 458 presses the limiting bearing 456 to prevent the bearing from coming out.

[0030] like Figure 4 As shown, the punching unit 4 also includes a counterweight 47; in this embodiment, the counterweight 47 is used selectively, and in combination with the weight of the floating part of the punching unit 4, it is convenient to punch balls of different specifications.

[0031] All technical features in this embodiment can be modified in appearance according to actual needs.

[0032] 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.
