Description

Technical Field

[0001] The utility model relates to the field of high-speed spindle processing, in particular to a clamping tool for high-speed spindle processing. Background Art

[0002] The high-speed spindle is also commonly known as the high-speed electric spindle. It is a new technology that has emerged in the field of CNC machine tools in recent years. It integrates the machine tool spindle and the spindle motor into one, and directly drives the machine tool spindle through a built-in electric motor, realizing the "zero transmission" of the machine tool, that is, eliminating the traditional pulley drive and gear drive, thereby greatly shortening the length of the main transmission chain. When the high-speed spindle is processed, the spindle will be clamped and limited by the tooling to ensure that the workpiece remains stable during high-speed rotation and processing, thereby achieving high-precision processing effects.

[0003] Existing clamping fixtures are mostly used in one direction when limiting the high-speed spindle. Since different high-speed spindles have different sizes, dimensions and processing requirements, if the clamping fixture is inconvenient to adjust, it may not be able to adapt to the clamping needs of different high-speed spindles, which may cause deviations of the high-speed spindle during the processing, thereby affecting the processing accuracy and workpiece quality. At the same time, it limits the scope of application and flexibility of the clamping fixture, and reduces the processing efficiency and production capacity of the machine tool.

[0004] Therefore, the above-mentioned existing clamping fixtures are mostly used in one direction when limiting the high-speed spindle. Since different high-speed spindles have different requirements in size, dimensions and processing, if the clamping fixture is inconvenient to adjust, it may cause the high-speed spindle to deviate during the processing. A clamping fixture for high-speed spindle processing can be designed, and an adjustable clamping limit structure can be used to improve the processing accuracy and applicability of the clamping fixture. Utility Model Content

[0005] In order to overcome the problem that existing clamping fixtures are mostly used in one direction when limiting the high-speed spindle, since different high-speed spindles have different sizes, dimensions and processing requirements, if the clamping fixture is inconvenient to adjust, it may cause the high-speed spindle to deviate during the processing process.

[0006] The technical solution of the utility model is: a clamping tool for high-speed spindle processing, comprising a circular base, a limit assembly and a clamping assembly; a limit assembly is provided on the upper middle portion of the circular base for shrinking and adjusting according to the size of the high-speed spindle and limiting and fixing it, and two groups of clamping assemblies are provided around the upper edge of the circular base for rotating and adjusting according to the limited position of the high-speed spindle and clamping and fixing it, the clamping assembly comprises an L-shaped telescopic sleeve, an arc-shaped slider, a rectangular telescopic column, a cylinder, a first rotating shaft, a guide column, a second rotating shaft, a connecting plate, a rotating ring sleeve, a rotating shaft, a connecting block, a connecting rotating shaft, an arc-shaped clamping plate and a second arc-shaped rubber pad, a connecting block is installed at one end of the rotating shaft, and a connecting rotating shaft is provided laterally symmetrically on the side of the connecting block away from the rotating shaft, the arc-shaped clamping plate is rotatably connected to the connecting block through the connecting rotating shaft, and a second arc-shaped rubber pad is installed on the inner side of the arc-shaped clamping plate.

[0007] Preferably, the high-speed spindle is first placed on the circular base, and then the limiting component is contracted and adjusted according to the size of the high-speed spindle to further limit and fix it, and then the clamping component is rotated and adjusted according to the limited position of the high-speed spindle, and it is finally clamped and fixed. Through the adjustable clamping limiting structure, it can quickly adapt to high-speed spindles of different sizes and dimensions, making the clamping tooling more flexible, improving the applicability of the equipment, and at the same time reducing the time for replacing the fixture and adjusting the equipment, improving processing efficiency and production capacity, and also ensuring that the high-speed spindle maintains a precise position and posture during the processing process, which helps to reduce processing errors and improve the processing accuracy and workpiece quality of the workpiece.

[0008] Preferably, multiple groups of suction cups are installed around the edge of the lower end of the circular base, a circular limit groove for placing the high-speed spindle is provided in the middle of the upper part of the circular base, four groups of rectangular slides for sliding the limit assembly are provided around the outer periphery of the circular limit groove of the circular base, and an annular slide for sliding the clamping assembly is provided at the upper edge of the circular base. The circular base is firmly placed at the processing position by the suction cup to avoid the influence of external force of the hand and the displacement of the circular base. The circular limit groove is convenient for the initial positioning of the high-speed spindle, the rectangular slide is convenient for the contraction and movement of the limit assembly, and the annular slide is convenient for the clamping assembly to fix the column high-speed spindle, drive the high-speed spindle to process from different directions, and improve the flexibility of the clamping tooling.

[0009] Preferably, the limiting assembly includes an arc-shaped telescopic sleeve, an arc-shaped telescopic plate, a latch, a rectangular slider and a first arc-shaped rubber pad. The first arc-shaped rubber pad is installed on the inner side of the arc-shaped telescopic sleeve, and the lower end of the arc-shaped telescopic sleeve is installed. A driver is provided inside the rectangular slider, and the rectangular slider drives the arc-shaped telescopic sleeve to slide along the rectangular groove and connect with the circular base. When the high-speed spindle is placed, the latch is pulled out, and then the driver drives the rectangular slider to drive the arc-shaped telescopic sleeve to slide along the rectangular groove and connect with the circular base, so that the first arc-shaped rubber pad continues to approach and fit the high-speed spindle, limiting and fixing its lower end. At the same time, the first arc-shaped rubber pad can increase friction to avoid offset during the high-speed spindle processing, affecting the quality of the final high-speed spindle processing.

[0010] Preferably, four groups of arc-shaped telescopic sleeves are arranged around, and an arc-shaped telescopic plate is arranged between every two groups of arc-shaped telescopic sleeves. A latch is provided at the connection between the arc-shaped telescopic plate and the arc-shaped telescopic sleeve. Multiple groups of positioning holes for the latch to pass through are provided along the arc-shaped telescopic plate. During the contraction and limiting process, the arc-shaped telescopic plate moves along the arc-shaped telescopic sleeve. When it is confirmed that the fixation is completed, the latch passes through the arc-shaped telescopic sleeve and is positioned and connected to the arc-shaped telescopic plate through the positioning hole for auxiliary fixation, thereby improving the stability of the clamping tooling.

[0011] The L-shaped telescopic sleeve is provided with a rectangular telescopic column, and the lower end of the rectangular telescopic column is provided with an arc slide, and the interior of the arc slide is provided with a driver, and the arc slide drives the rectangular telescopic column to slide along the annular groove and is connected to the circular base. The upper end of the L-shaped telescopic sleeve is provided with a cylinder, and the end of the L-shaped telescopic sleeve away from the rectangular telescopic column is provided with a first rotating shaft. If it is necessary to process other parts of the high-speed spindle, the latch is first pulled out, the arc telescopic sleeve is moved and extended, and the limit fixation on the lower end of the high-speed spindle is removed. Then, the L-shaped telescopic sleeve is driven by the cylinder to drive the arc clamping plate to move upward along the rectangular telescopic column to lift the high-speed spindle. Then, the driving of the driver drives the rotating shaft to rotate the high-speed spindle along the rotating ring sleeve to a suitable angle. Finally, the driving of the driver drives the arc slide to drive the rectangular telescopic column to slide along the annular groove and be connected to the circular base, so that the high-speed spindle is adjusted to a suitable processing orientation. During this process, the second arc rubber pad can increase the friction force to avoid the high-speed spindle from falling when adjusting the angle and orientation of the high-speed spindle.

[0012] Preferably, the guide column is rotatably connected to the L-shaped telescopic sleeve through a first rotating shaft, a second rotating shaft is installed at one end of the guide column away from the first rotating shaft, the connecting plate is rotatably connected to the guide column through the second rotating shaft, a rotating ring sleeve is installed on the side of the connecting plate away from the second rotating shaft, and a driver is installed on one side of the first rotating shaft and the second rotating shaft. According to the limited position of the high-speed main shaft, the guide column is first driven by the driver to rotate to a suitable angle through the first rotating shaft and the L-shaped telescopic sleeve, and at the same time, the connecting plate is driven by the driver to rotatably connect to the guide column through the second rotating shaft, so that the arc-shaped clamping plate is always perpendicular to the high-speed main shaft.

[0013] Preferably, a rotating shaft is provided inside the rotating ring sleeve, a driver is provided inside the rotating shaft, an infrared distance detector is installed on the upper end of the connecting block, and a driver is installed on the upper end of the connecting shaft. Through detection by the infrared distance detector and continuous rotation adjustment, the high-speed spindle is located between the two sets of connecting shafts. Then, through the drive of the driver, the arc clamping plate is rotatably connected to the connecting block through the connecting shaft, driving the second arc rubber pad to fit the high-speed spindle, fixing and clamping it, and then processing can be carried out.

[0014] Beneficial effects of the utility model:

[0015] 1. First, place the high-speed spindle on the circular base. Then, the limit assembly is retracted and adjusted according to the size of the high-speed spindle to further limit and fix it. Then, the clamping assembly is rotated and adjusted according to the limited position of the high-speed spindle, and it is finally clamped and fixed. The adjustable clamping limit structure can quickly adapt to high-speed spindles of different sizes and dimensions, making the clamping tooling more flexible and improving the applicability of the equipment. At the same time, it reduces the time for replacing fixtures and adjusting equipment, improving processing efficiency and production capacity. In addition, it can ensure that the high-speed spindle maintains a precise position and posture during the processing, which helps to reduce processing errors and improve the processing accuracy and quality of the workpiece.

[0016] 2. After the high-speed spindle is placed, the pin is pulled out. Then, the driver drives the rectangular slider to drive the arc-shaped telescopic sleeve to slide along the rectangular slide groove and connect with the circular base. This makes the first arc-shaped rubber pad continuously approach and fit the high-speed spindle, limiting and fixing its lower end. At the same time, the first arc-shaped rubber pad can increase friction to prevent the high-speed spindle from deflecting during machining, which would affect the quality of the final high-speed spindle machining.

[0017] 3. If other parts of the high-speed spindle need to be processed, first pull out the pin, the arc-shaped telescopic sleeve moves and extends, and the limit fixation on the lower end of the high-speed spindle is removed. Then, driven by the cylinder, the L-shaped telescopic sleeve drives the arc-shaped clamping plate to move upward along the rectangular telescopic column to lift the high-speed spindle. Then, driven by the driver, the rotating shaft drives the high-speed spindle to rotate along the rotating ring sleeve to the appropriate angle. Finally, driven by the driver, the arc-shaped slider drives the rectangular telescopic column to slide along the annular groove and connect with the circular base to adjust the high-speed spindle to the appropriate processing position. During this process, the second arc-shaped rubber pad can increase the friction to prevent the high-speed spindle from falling when adjusting the angle and position of the high-speed spindle.

A cylinder 304 is installed at the upper end of the L-shaped telescopic sleeve 301, and a first rotating shaft 305 is installed at the end of the L-shaped telescopic sleeve 301 away from the rectangular telescopic column 303. If other parts of the high-speed spindle need to be processed, the pin 204 is pulled out first, the arc-shaped telescopic sleeve 201 moves and stretches, and the limit fixation on the lower end of the high-speed spindle is removed, and then the cylinder is used to press the pin 204 to move the arc-shaped telescopic sleeve 201. Driven by 304, the L-shaped telescopic sleeve 301 drives the arc-shaped clamping plate 313 to move upward along the rectangular telescopic column 303, lifting the high-speed spindle. Then, driven by the driver, the rotating shaft 310 drives the high-speed spindle to rotate to a suitable angle along the rotating ring sleeve 309. Finally, driven by the driver, the arc-shaped slider 302 drives the rectangular telescopic column 303 to slide along the annular slide groove 102 and connect with the circular base 1, so that the high-speed spindle is adjusted to a suitable processing orientation. In this process, the second arc-shaped rubber pad 314 can increase the friction force to avoid the high-speed spindle from falling when adjusting the angle and orientation of the high-speed spindle.

Through detection by the infrared distance detector, the high-speed spindle is positioned between the two sets of connecting rotating shafts 312 through continuous rotation adjustment. Then, the arc-shaped clamping plate 313 is driven by the driver to rotate and connect with the connecting block 311 through the connecting rotating shaft 312, driving the second arc-shaped rubber pad 314 to fit the high-speed spindle, fixing it and then processing can be carried out.

[0030] If it is necessary to process other parts of the high-speed spindle, first pull out the pin 204, the arc-shaped telescopic sleeve 201 moves and extends, and the limit fixation on the lower end of the high-speed spindle is removed. Then, driven by the cylinder 304, the L-shaped telescopic sleeve 301 drives the arc-shaped clamping plate 313 to move upward along the rectangular telescopic column 303 to lift the high-speed spindle. Then, driven by the driver, the rotating shaft 310 drives the high-speed spindle to rotate along the rotating ring sleeve 309 to a suitable angle. Finally, driven by the driver, the arc-shaped slider 302 drives the rectangular telescopic column 303 to slide along the annular groove 102 and connect with the circular base 1, so that the high-speed spindle is adjusted to a suitable processing orientation. During this process, the second arc-shaped rubber pad 314 can increase the friction to prevent the high-speed spindle from falling when adjusting the angle and orientation of the high-speed spindle.

[0031] Through the above steps, the high-speed spindle is first placed on the circular base 1, and then the limiting component is contracted and adjusted according to the size of the high-speed spindle to further limit and fix it, and then the clamping component is rotated and adjusted according to the limited position of the high-speed spindle, and it is finally clamped and fixed. Through the adjustable clamping limiting structure, it can quickly adapt to high-speed spindles of different sizes and dimensions, making the clamping tool more flexible, improving the applicability of the equipment, and at the same time reducing the time for replacing the fixture and adjusting the equipment, improving processing efficiency and production capacity, and also ensuring that the high-speed spindle maintains a precise position and posture during the processing process, which helps to reduce processing errors and improve the processing accuracy and workpiece quality of the workpiece, so as to solve the problem that the existing clamping tool is mostly used in one direction when limiting the high-speed spindle. Since different high-speed spindles have different requirements in size, size and processing, if the clamping tool is inconvenient to adjust, it may cause the high-speed spindle to deviate during the processing.
