[0001] The utility model relates to the field of column chuck structure design, in particular to a column chuck which is easy to maintain. Background Art

[0002] Post-type chucks are a common tool in the metalworking industry, particularly in machine shops, where they are used to secure and support workpieces during machining. These chucks feature a solid center, often referred to as the "post," which provides additional support during machining, thereby enhancing workpiece stability.

[0003] The disassembly and assembly of traditional column chucks usually require complicated steps, especially when it comes to the disassembly of internal gears and sliding parts. It not only requires the operation of professionals, but also requires the use of specific tools, which increases the time and labor costs of maintenance.

[0004] Therefore, it is urgent to propose a column chuck that is convenient to maintain. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a column chuck that is easy to maintain.

[0006] The technical implementation scheme of the utility model is: a column chuck that is easy to maintain, including a chuck body, a connecting disk, a screw, a rotating shaft, a gear 1, a matching disk, a gear ring 1, a spiral slide, a sliding block, a clamping block, a screw, a gear 2, a movable block, a gear ring 2 and a rotating frame. The rear end of the chuck body is connected to the connecting disk, and a screw is provided between the connecting disk and the inside of the chuck body. The inside of the connecting disk is symmetrical along the circumference and rotatably provided with a plurality of rotating shafts. Gears 1 are provided at the ends of the plurality of rotating shafts, and each gear 1 is arranged vertically and equidistantly inside the connecting disk. A matching disk is rotatably provided between the chuck body and the connecting disk, and a gear ring 1 is provided at the rear end of the matching disk. The teeth of the gear ring 1 are aligned with the adjacent gears 1. The front end of the plurality of sliding blocks is connected to the chuck body through the plurality of screw rods, and a plurality of gears on the front end of the plurality of screw rods are engaged with each other. A plurality of movable blocks are provided on the rear side of the outer side of the chuck body for sliding sliding movement. A plurality of sliding blocks are symmetrically and slidingly provided with a plurality of sliding blocks in the front part of the chuck body along the circumferential direction. The rear parts of the plurality of sliding blocks pass through the chuck body, and the rear parts of the plurality of sliding blocks are provided with sliding teeth that rotate with the spiral slideway. A plurality of sliding blocks are clamped with a clamping block in the front part. Two screw rods are threadedly provided between the clamping block and the inside of the sliding block. A gear 2 is provided at the front end of each screw rod, and the two gears on the same clamping block are engaged with each other. A plurality of movable blocks are provided on the rear side of the outer side of the chuck body for sliding movement along the circumferential direction. A gear ring 2 is provided between the outer parts of the plurality of movable blocks in a ring-shaped rotation. The gear teeth at the front part of the gear ring 2 are engaged with each gear 2 on the outward side, and a rotating frame is provided in a ring shape on the outer side of the gear ring 2.

[0007] As a further preferred solution, a protruding connecting shaft is provided at the rear center of the mating disc, and the connecting shaft runs through the interior of the connecting disc.

[0008] As a further preferred solution, a straight adjustment groove is provided on the inner front side of each screw.

[0009] As a further preferred solution, after pushing the rotating frame, it drives each movable block to slide synchronously on the outside of the chuck body. When the ring gear 2 moves and contacts the gear 2, the ring gear 2 rotates, thereby realizing the disassembly of each screw.

DETAILED DESCRIPTION

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Embodiment: A column chuck that is easy to maintain, such as Figure 1-Figure 4As shown, it includes a chuck body 1, a connecting disk 2, a screw 3, a rotating shaft 4, a gear 1 5, a matching disc 6, a gear ring 1 7, a spiral slide 8, a sliding block 9, a clamping block 10, a screw 11, a gear 2 12, a movable block 13, a gear ring 2 14 and a rotating frame 15. The chuck body 1 is used to fix the workpiece and serve as the installation basis for other components. The rear end of the chuck body 1 is docked with a connecting disk 2, and the connecting disk 2 connects the chuck body 1 with an external drive device, such as a motor. A screw 3 is threaded between the connecting disk 2 and the inside of the chuck body 1. The screw 3 fixes the connecting disk 2 and the chuck body 1 to facilitate disassembly and installation. The inner rear side of each screw 3 and the outward side of each rotating shaft 4 are provided with a hexagonal fitting groove of the same specification. The interior of the connecting disk 2 is symmetrical along the circumferential direction and is provided with a plurality of rotating shafts. The driving shaft 4 is driven by the inside of the connecting disk 2 and realizes synchronous rotation through the gear 5. A gear 5 is provided at the end of several rotating shafts 4. The gear 5 is meshed with the ring gear 7 to transmit the rotation of the rotating shaft 4 to the matching disc 6. Each gear 5 is arranged vertically and equidistantly inside the connecting disk 2. A matching disc 6 is provided for rotation between the chuck body 1 and the connecting disk 2. The matching disc 6 is meshed with the gear 5 through its ring gear 7 to realize rotation and drive the spiral slideway 8 to rotate. A protruding connecting shaft is provided at the center of the rear part of the matching disc 6. The connecting shaft passes through the inside of the connecting disk 2. A ring gear 7 is provided at the rear end of the matching disc 6. The teeth of the ring gear 7 are meshed with the adjacent gears 5 to transmit the rotation of the matching disc 6 to the gear 5. The front of the matching disc 6 A spiral slideway 8 is provided at the end, and the rotation of the spiral slideway 8 causes the radial sliding of the sliding block 9 to realize the radial movement of the card block 10. The front part of the chuck body 1 is symmetrically and slidingly provided with three sliding blocks 9 along the circumferential direction. The sliding block 9 cooperates with the spiral slideway 8 through sliding teeth to realize radial sliding, driving the card block 10 to move. The rear parts of the three sliding blocks 9 all pass through the chuck body 1, and the rear parts of the three sliding blocks 9 are all provided with sliding teeth that rotate with the spiral slideway 8. The front parts of several sliding blocks 9 are all clamped with a card block 10, and the card block 10 fixes the workpiece, and the clamping or release of the workpiece is achieved by the movement of the sliding block 9. Two screws 11 are provided between the card block 10 and the inside of the sliding block 9. The screw 11 fixes the card block 10 and the sliding block 9, and the screw 11 fixes the card block 10 and the sliding block 9, and the gear 12 and the ring gear 1 are connected together. 4 cooperates to achieve disassembly and assembly, a straight-shaped adjustment groove is provided on the inner front side of each screw rod 11, and a gear 2 12 is provided at the front end of each screw rod 11. The gear 2 12 meshes with the gear ring 2 14 to transmit the rotation of the gear ring 2 14 to the screw rod 11, and the two gears on the same clamping block 10 mesh with each other. A plurality of movable blocks 13 are provided on the outer rear side of the chuck body 1 for sliding along the circumferential direction. The movable blocks 13 cooperate with the gear 2 12 through the gear ring 2 14 to achieve the disassembly of the screw rod 11. The outer sides of the plurality of movable blocks 13 are provided with a gear ring 2 14 for annular rotation. The gear ring 2 14 meshes with the gear 2 12 and is rotated by moving the rotating frame 15. The gear teeth at the front of the gear ring 2 14 mesh with the gears 2 12 on the outward side, and the outer side of the gear ring 2 14 is provided with a rotating frame 15 in an annular shape.The rotating frame 15 is manually pushed to move the movable block 13, causing the second gear ring 14 to rotate. After the rotating frame 15 is pushed, it drives each movable block 13 to slide synchronously on the outside of the chuck body 1. When the second gear ring 14 moves and contacts the second gear 12, the second gear ring 14 rotates, allowing the screws 11 to be disassembled.

[0022] like Figure 2 As shown, it also includes an oil dripping tube 101 and a sealing cover 102. A bent oil dripping tube 101 is connected to one side of the upper part of the chuck body 1. The oil dripping tube 101 is used to inject lubricating oil into the inside of the chuck body 1 to ensure lubrication of the components. The sealing cover 102 is hinged at the end of the oil dripping tube 101 to seal the oil dripping tube 101 to prevent leakage of lubricating oil.

[0023] When maintenance or part replacement is required, the rotating frame 15 on the rear side of the chuck body 1 can be pushed. The rotating frame 15 drives the movable block 13 to slide synchronously, so that the ring gear 14 moves outward and contacts the gear 2 12, thereby driving the ring gear 14 to rotate. The rotation of the ring gear 14 is converted into the rotation of the screw 11, which makes it easy to remove the screw 11 from the sliding block 9. The straight-shaped adjustment groove at the front end of the screw 11 facilitates the use of tools for disassembly and assembly. After disassembly, the screw 3 between the connecting disk 2 and the chuck body 1 can be unscrewed. The hexagonal interlocking groove design of the screw 3 and the rotating shaft 4 makes disassembly and assembly more convenient; and during maintenance, lubricating oil can be injected into the interior through the oil drip tube 101 to ensure that all moving parts are in good lubrication condition.

[0024] When the workpiece needs to be clamped initially, the rear end of the chuck body 1 docks with the connecting disk 2 and is fixed together by the internal screws 3. There is a protruding connecting shaft at the center of the mating disk 6. This shaft passes through the connecting disk 2 and is used to connect to an external drive device (such as a motor). When the drive device is started, it drives the mating disk 6 to rotate. When the mating disk 6 rotates, its ring gear 1 7 will mesh with the gear 1 5, thereby driving all the rotating shafts 4 to rotate synchronously. At the same time, the spiral slide 8 at the front end of the mating disk 6 also begins to rotate. The rotation of the spiral slide 8 will cause the sliding block 9 to slide radially. Because the rear part of the sliding block 9 is provided with sliding teeth that match the spiral slide 8, when the spiral slide 8 rotates, the sliding block 9 can slide along the track inside the chuck body 1, thereby achieving radial expansion or contraction. As the sliding block 9 slides, the clamping block 10 will also move closer to or away from the center of the chuck accordingly, thereby achieving clamping or release of the workpiece.

[0025] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to illustrate rather than limit the present invention, which shall be defined by the claims.
