Description

Technical Field

[0001] The utility model relates to the technical field of lathe clamping claws, in particular to a lathe rapid claw repairing tool. Background Art

[0002] Mechanical production is inseparable from mechanical processing. General mechanical parts, especially high-precision mechanical parts, are produced and processed by lathes. Lathes are divided into ordinary lathes and CNC lathes. During mechanical processing, the workpiece to be processed needs to be clamped and positioned by clamping jaws. The clamping jaws are the most important components in mechanical processing. The clamping jaws are divided into soft jaws and hard jaws. Generally, lathes use hard jaws to turn bars, blanks, etc. The clamping relies on labor. Soft jaws can clamp parts to reduce damage and improve coaxiality, playing an important role in fine processing and secondary clamping.

[0003] However, the existing lathe hydraulic chuck external support soft jaw repair jaw lacks an external support fixing structure, and the repair jaw is not a theoretical complete circle. The theoretical diameter size of the repair jaw has a large error with the inner hole diameter of the workpiece, and it is difficult to accurately support the inner diameter of the workpiece, which can easily cause the workpiece to shake during processing, resulting in errors in workpiece processing and inconvenience for users. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a lathe quick jaw trimming tool, which solves the problem that the existing lathe hydraulic chuck external support soft jaw trimming tool lacks an external support fixing structure, and the trimming jaw is not a theoretical complete circle. The error between the theoretical diameter size of the trimming jaw and the inner hole diameter of the workpiece is large, and it is difficult to accurately support the inner diameter of the workpiece, which can easily cause the workpiece to shake during processing, resulting in errors in workpiece processing and inconvenience for users.

[0005] The utility model provides the following technical solution: a lathe quick jaw repair tool, comprising a chuck base, a middle connecting block is provided in the middle of the side surface of the chuck base, three driving grooves are evenly opened on the side surface of the chuck base, a driving screw is rotatably provided in the driving groove, an external support friction block is provided on the driving groove, and a connecting slider is provided at the bottom end of the external support friction block, the connecting slider is slidably inserted in the driving groove, the driving screw thread passes through the middle of the connecting slider, a driving screw sleeve is provided on the driving screw, and the driving screw sleeve is provided with a fixed connecting ring, the driving screw sleeve and the connecting slider are fixedly connected by the fixed connecting ring, and a supporting soft jaw is provided on the side of the chuck base, and the inner wall of the supporting soft jaw is evenly opened with three inner wall friction grooves.

[0006] Preferred technical solution 1: The driving groove is evenly arranged at 120° on the side edge of the chuck base.

[0007] Preferred technical solution 2: Two connecting blocks are symmetrically arranged on both sides of the external support resistance block.

[0008] Preferred technical solution three: The end of the driving screw is provided with a connecting block for easy rotation.

[0009] This solution can make it more convenient for users to rotate the drive screw.

[0010] Preferred technical solution four: the supporting soft claws are made of deformable rubber material.

[0011] This solution enables the supporting soft claws to deform and better fit the inner diameter of the workpiece when the outer supporting resistance block resists the supporting soft claws.

[0012] Preferred technical solution five: the three inner wall abutment grooves are evenly distributed at 120° on the inner side wall of the supporting soft claw.

[0013] This solution can ensure that the inner wall resistance groove can be better resisted by the outer support resistance block.

[0022] See also Figure 1-4 ,

[0023] Embodiment 1: A lathe quick jaw repair tool includes a chuck base 1, a middle connecting block 2 is provided in the middle of the side of the chuck base 1, three driving grooves 3 are evenly opened on the side of the chuck base 1, a driving screw 4 is rotatably provided in the driving groove 3, an external support resistance block 5 is provided on the driving groove 3, and a connecting slider 6 is provided at the bottom end of the external support resistance block 5, and the connecting slider 6 is slidably inserted in the driving groove 3.

[0024] The thread of the driving screw 4 passes through the middle of the connecting slider 6, and a driving screw sleeve 7 is provided on the driving screw 4. The driving screw sleeve 7 is provided on the driving screw 4. A fixed connecting ring 8 is provided. The driving screw sleeve 7 and the connecting slider 6 are fixedly connected by the fixed connecting ring 8. A supporting soft claw 9 is provided on the side of the chuck base 1, and three inner wall resistance grooves 10 are evenly opened on the inner wall of the supporting soft claw 9.

[0025] The driving grooves 3 are evenly arranged at 120° on the side edges of the chuck base 1 .

[0026] Two connecting blocks are symmetrically arranged on both sides of the outer supporting and resisting block 5 .

[0027] Embodiment 2: The difference between this embodiment and embodiment 1 is that a connecting block for facilitating rotation is provided at the end of the driving screw 4 .

[0028] This makes it more convenient for the user to rotate the driving screw 4.

[0029] Embodiment 3: The difference between this embodiment and embodiment 1 is that the supporting soft claws 9 are made of deformable rubber material.

[0030] When the outer support abutment block 5 abuts against the supporting soft claw 9, the supporting soft claw 9 can be deformed to better fit the inner diameter of the workpiece.

[0031] Embodiment 4: The difference between this embodiment and embodiment 1 is that the three inner wall abutment grooves 10 are evenly distributed at an angle of 120° on the inner side wall of the supporting soft claw 9 .

[0032] This allows the inner wall contact groove 10 to be better contacted by the outer support contact block 5 .

[0033] In this embodiment, since the existing lathe hydraulic chuck external support soft jaws repair jaws lack an external support fixing structure, and the repair jaws are not theoretically complete circles, the error between the theoretical diameter size of the repair jaws and the inner hole diameter of the workpiece is large, and it is difficult to provide precise fit support for the inner diameter of the workpiece, which can easily cause the workpiece to shake during processing, resulting in errors in workpiece processing, and inconvenience for users.

[0034] In summary, in specific implementation, when the user needs to support the inner diameter of the workpiece, the user first needs to put the workpiece on the outside of the external support resistance block 5, and the support soft claws 9 are put between the workpiece and the external support resistance block 5. At this time, the user can rotate the drive screw 4 separately so that the drive screw 4 can drive the drive sleeve 7 to move, and the drive sleeve 7 is connected to the connecting slider 6 through a fixed connecting ring 8, and the connecting slider 6 is slidably inserted in the drive groove 3, so that the rotation of the drive screw 4 can pull the connecting slider 6 through the drive sleeve 7.

[0035] At the same time, the outer support resistance block 5 is driven to move toward the edge of the chuck base 1 by connecting the slider 6, so that the outer edge of the outer support resistance block 5 can resist the inner wall of the supporting soft claw 9, so that the supporting soft claw 9 can fill the gap between the outer support resistance block 5 and the inner diameter of the workpiece, ensuring that the outer support resistance block 5 can fit and resist the inner diameter of the workpiece, so that the workpiece mounted on the side of the chuck base 1 can be supported and resisted more stably, ensuring that the workpiece is more stable during processing, greatly reducing large errors in the workpiece during processing, and facilitating user use.
