Description

Technical Field

[0001] The utility model relates to the technical field of shaft processing, in particular to a switchable tailstock. Background Art

[0002] Gear shafts are a type of transmission parts that are widely used in modern machinery. They are widely used in machinery, automobiles, aviation, printing, instrumentation and other industries. Gear shafts and other parts are clamped and installed by the tailstock on the machine tool and then the parts are processed.

[0003] Since some special shaft parts are long but the processing range of gears is short, the existing machine tools meet the processing range requirements, but the clamping stroke generally does not meet the requirements, and replacing large machine tools will waste resources. In response to this phenomenon, it is urgent to design and develop a switchable tailstock that can increase the clamping range of the machine tool and is easy to install and disassemble. Utility Model Content

[0004] In view of the above existing technical problems, the utility model provides a switchable tailstock, which is characterized by comprising a tailstock mounting platform, a fixed top tailstock, a driving mechanism, a movable plate, a guide slide rail, a detachable top tailstock, and mounting screws. The fixed top tailstock is fixedly mounted on one end of the tailstock mounting platform, and a mounting driving mechanism is arranged on the other end of the tailstock mounting platform. The driving mechanism is connected to the movable plate, and the detachable top tailstock is fixed on the movable plate by mounting screws. The two ends of the movable plate are respectively slidably connected with the guide slide rails mounted on the tailstock mounting platform.

[0005] The driving mechanism is composed of a motor seat, a driving motor and a screw rod. The motor seat is fixedly mounted on the side of the tailstock mounting platform. The driving motor is mounted on the motor seat. The output end of the driving motor is connected to the screw rod. The screw rod is connected to a moving groove arranged on the tailstock mounting platform through a bearing. The moving plate is threadedly connected to the screw rod.

[0006] The detachable top tailstock is provided with a lifting ring, the number of which is ≥1, and is used to disassemble and remove the detachable top tailstock.

[0007] Specifically, a control switch is installed on the side of the tailstock mounting platform, and the control switch is electrically connected to the drive motor to control the operation of the drive motor.

[0008] Specifically, the machining axis of the fixed tailstock and the machining axis of the detachable tailstock are on the same straight line.

[0009] Beneficial effects of the utility model:

[0010] The utility model arranges a mounting moving mechanism on the tailstock mounting platform, and drives the moving plate to move axially by a driving motor and a screw rod, that is, controls the movement of a detachable top tailstock detachably mounted on the moving plate to adjust the distance between the detachable top tailstock and the fixed top tailstock. Not only can the distance between the two top tailstocks be adjusted to meet the needs of processing both ends of the same part, but the processing range in front of the two top tailstocks can also be adjusted, so that the two top tailstocks can process the two parts separately, thereby enhancing practicality.

[0011] When the length of the part to be processed is very long, moving the detachable tailstock to adjust the distance between the two tailstocks to the farthest still does not meet the required range for processing the part. At this time, the mounting screws can be removed and the detachable tailstock can be removed through the lifting ring on the tailstock mounting table. Only one fixed tailstock is left on the tailstock mounting table, which greatly increases the clamping range of the machine tool. There is no need to replace it with a larger machine tool, thereby increasing the scope of processing application. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Example 1

[0020] As shown in the figure, the fixed top tailstock 2 is fixedly mounted on one end of the tailstock mounting platform 1, and the other end of the tailstock mounting platform 1 is provided with a mounting drive mechanism, the motor seat 50 in the driving mechanism is fixedly mounted on the side of the tailstock mounting platform 1, and the driving motor 51 is installed on the motor seat 50, and the output end of the driving motor 51 is connected to the screw rod 52, and the screw rod 52 is connected to the moving groove 11 set on the tailstock mounting platform 1 through a bearing, and the screw rod 52 is threadedly connected to the moving plate 4, and the moving plate 4 is fixed with the detachable top tailstock 3 by installing screws 7, and the two ends of the moving plate 4 are respectively slidably connected with the guide slide rails 6 installed on the tailstock mounting platform 1, and the processing axis of the fixed top tailstock 2 and the processing axis of the detachable top tailstock 3 are on the same straight line.

[0021] Among them, a lifting ring 31 is provided on the detachable top tailstock 3, and the number of the lifting ring 31 is ≥1, which is used to disassemble and remove the detachable top tailstock. A control switch 11 is installed on the side of the tailstock mounting table 1. The control switch 11 is electrically connected to the drive motor 51 to control the operation of the drive motor 51.

[0022] Example 2

[0023] For some parts to be processed whose two ends need to be processed, two top tailstocks installed on the tailstock mounting table 1 are used to process the two ends of the same part. The present application sets up an installation moving mechanism on the tailstock mounting table 1, and the operator starts the forward and reverse rotation of the drive motor 51 by controlling the switch 511. The drive motor 51 and the screw rod 52 drive the axial movement of the movable plate 4, that is, controls the movement of the detachable top tailstock 3 detachably installed on the movable plate 4 to adjust the distance between the detachable top tailstock 3 and the fixed top tailstock 2 to meet the processing requirements of the two ends of parts of different lengths.

[0024] Example 3

[0025] For some parts that only need to be processed at one end, the two top tailstocks installed on the tailstock mounting table 1 process the parts separately, which improves the processing efficiency. In addition, the distance between the two top tailstocks can be adjusted to adjust the processing range in front of the two top tailstocks, so as to fully utilize the processing space required for processing parts of different sizes and enhance practicality.

[0026] When the length of the part to be processed is very long, moving the detachable top tailstock 3 to adjust the distance between the two top tailstocks to the farthest still does not meet the required range for processing the part. At this time, the mounting screws 7 can be removed and the detachable top tailstock 3 can be removed through the lifting equipment through the lifting ring 31 on the detachable top tailstock 3. Only one fixed top tailstock 2 is left on the tailstock mounting table 1, which greatly increases the clamping range of the machine tool and does not need to be replaced with a larger machine tool.
