Description

Technical Field

[0001] The present application relates to the technical field of lathe processing, and in particular to a fixing device for a lathe. Background Art

[0002] Lathe is an important machine tool widely used in machinery manufacturing, automobile, chemical industry, light industry and other fields. The production and manufacturing of valves that can be seen everywhere in life are also inseparable from lathes.

[0003] Valves can be divided into different types according to their functions, including gate valves, stop valves, throttle valves, ball valves, butterfly valves, etc. Various types of valves are processed into two-way and three-way valves according to the needs of installation and use. It can be seen that the shapes of various types of valves produced and processed are also different. However, when processing valves on a lathe, the valve is mainly clamped and fixed by a fixing fixture to facilitate lathe turning, grinding and other processing. There are multiple processing surfaces on the valve. After one side is processed, the fixed position of the valve needs to be adjusted by the fixing fixture so that the remaining processing surfaces can be processed smoothly. However, the shape of the valve is complex, and each processing surface may be different. The fixing fixture is not convenient for clamping different parts of the valve, and the clamping may be unstable, which needs further improvement. Utility Model Content

[0004] In order to improve the stability problem of the valve clamping part, the present application provides a fixing device for a lathe.

[0005] The present application provides a fixing device for a lathe, which adopts the following technical solution:

[0006] A fixing device for a lathe comprises a machine tool body, a fixed base arranged on the machine tool body, and a pressing assembly installed on the fixed base, wherein a valve is placed on the fixed base, the pressing assembly is used to press the valve from the top of the fixed base, the fixed base is also rotatably connected to the machine tool body, and a rotating assembly for driving the fixed base to rotate is provided on the machine tool body.

[0007] By adopting the above technical solution, the valve is placed on a fixed base, and then a pressing assembly is used to press the valve onto the fixed base. Finally, a rotating assembly is used to drive the fixed base to rotate, so that the processing surface of the valve can be aligned with the tool on the machine tool. In the process of valve processing, there is no need to fix the valve anyway, and only the valve alignment position needs to be adjusted by rotating. The operation is convenient and the structure is reliable.

[0008] Optionally, the rotating assembly includes a rotating shaft, a rotating worm wheel and a rotating worm, the rotating shaft is rotatably connected to the machine tool body, and one end of the rotating shaft is fixedly connected to the fixed base, and the other end extends from the bottom of the machine tool body and is fixedly connected to the rotating worm wheel, the rotating worm is rotatably connected to the bottom of the machine tool body, and the spiral teeth of the rotating worm are meshed with the rotating worm wheel, and the rod body of the rotating worm extends to the outside of the machine tool body.

[0009] By adopting the above technical solution, the worm is rotated by operating the rotating worm, thereby effectively driving the worm wheel and the rotating shaft to rotate together, thereby realizing the driving of the fixed base. The operation is convenient and the operation is far away from the inside of the machine tool body, which effectively improves the operational safety and is very reliable.

[0010] Optionally, the pressing assembly includes a mounting bracket arranged on the fixed base, a pressing cylinder connected to the mounting bracket, and a pressure plate connected to the pressing cylinder, and the output end of the pressing cylinder extends downward and is fixedly connected to the pressure plate.

[0011] By adopting the above technical solution, a pressing cylinder is used to drive the pressure plate to press the valve downward, thereby effectively pressing the valve onto the fixed base. The structure is reliable, ensuring the stability of the valve fixation.

[0012] Optionally, an anti-wear pad is also provided at the bottom of the pressure plate.

[0013] By adopting the above technical solution, the anti-wear pad is set to increase the friction between the pressure plate and the valve, reducing slipping. The flexibility of the anti-wear pad also reduces the wear of the pressure plate on the valve, and the structure is reliable.

[0014] Optionally, a clamping assembly for clamping the valve is further provided on the fixed base, and at least three groups of the clamping assemblies are provided on the peripheral side of the fixed base.

[0015] By adopting the above technical solution, the clamping assembly is set to further clamp the valve on the fixed base, and the setting of three groups of clamping assemblies enables both two-way and three-way valves to be firmly clamped, thereby reducing the shaking of the valve and making the valve structure more stable during the processing process.

[0016] Optionally, the clamping assembly includes two clamping plates, and the two clamping plates are arranged in at least three groups along the circumference of the fixed base. Each group of two clamping plates is relatively slidably connected to the fixed base, and the fixed base is provided with a sliding member for driving the two clamping plates to slide relative to each other.

[0017] By adopting the above technical solution, the two clamping plates are driven by the sliding member to slide relative to each other, thereby effectively clamping the valve, improving the stability of the valve, and having a simple and reliable structure.

[0018] Optionally, the sliding member includes a driving spring, and a connecting plate is provided on the fixed base near the clamping plate. One end of the driving spring is fixedly connected to the connecting plate, and the other end is fixedly connected to the clamping plate. The driving spring causes the two clamping plates to slide relatively close to each other.

[0019] By adopting the above technical solution, under the elastic force of the driving spring, the two clamping plates slide close to each other, thereby effectively clamping and fixing the valve. It is easy to use and can effectively adapt to valves of different sizes.

[0020] Optionally, a telescopic rod is further connected between the connecting plate and the clamping plate, the driving spring is sleeved on the telescopic rod, and two ends of the telescopic rod are respectively fixedly connected to the connecting plate and the clamping plate.

[0021] By adopting the above technical solution, the telescopic rod is arranged to reduce the shaking of the driving spring during use, thereby effectively making the driving spring stably drive the clamping plate to slide, and the structure is reliable.

[0022] In summary, this application includes the following beneficial technical effects:

[0023] 1. By setting a fixed base and a pressing assembly, the fixed base is rotatably connected to the machine tool body, and the pressing assembly can press the valve on the fixed base. Then the fixed base is rotated so that the valve on the fixed base is effectively aligned with the tool on the lathe body. Therefore, during the processing of the valve, there is no need to repeatedly adjust the valve. It is only necessary to rotate the fixed base so that different processing surfaces on the valve are aligned with the tool. It is very convenient, and the pressing method also makes the valve fixed reliably.

[0024] 2. Through the setting of the clamping plate and the driving spring, under the elastic force of the driving spring, the two clamping plates slide close to each other, thereby effectively clamping the valve, reducing the shaking and deviation of the valve on the fixed base, making it reliable.
