Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and in particular relates to an automatic centering and clamping device for high-precision shaft parts. Background Technology

[0002] In the field of machining, the machining accuracy of shaft parts has a crucial impact on the performance of the entire machine. To ensure machining quality, centering and clamping devices are needed to fix the workpiece and keep it in a stable and accurate position during machining.

[0003] However, current centering and clamping devices have the following problems: First, different diameter shaft parts require different fixtures, which increases production costs and time; second, manual adjustment of the clamping process is inefficient and cannot meet the needs of modern high-efficiency production. Utility Model Content

[0004] In order to overcome the shortcomings of existing technologies that require different clamps for shaft parts of different diameters and have low efficiency due to manual adjustment, this utility model provides a high-precision automatic centering and clamping device for shaft parts.

[0005] Technical solution: A high-precision automatic centering and clamping device for shaft parts includes a mounting base, a worktable, electric slide rails, sliders, mounting plates, clamping blocks, and arc plates. The worktable is fixed on the mounting base, and three electric slide rails are symmetrically fixed on the mounting base. The sliders are installed inside the electric slide rails, the mounting plate is set on the top of the sliders, and the clamping blocks are set at the end of the mounting plate. Arc plates are connected to the sides of the three sliders that are close to each other. One end of the arc plate has a U-shaped groove, and one end of the arc plate is inserted into the U-shaped groove of the adjacent arc plate.

[0006] Preferably, the high-precision automatic centering and clamping device for shaft parts also includes a pressure sensor, which is located inside the clamping block.

[0007] Preferably, the high-precision automatic centering and clamping device for shaft parts also includes a soft pad, which is disposed on the outside of the pressure sensor.

[0008] Preferably, the high-precision automatic centering and clamping device for shaft parts also includes a three-way clamp, which is installed at the center of the mounting base.

[0009] Preferably, the high-precision automatic centering and clamping device for shaft parts also includes a temperature sensor, which is mounted on the worktable.

[0010] Preferably, the high-precision automatic centering and clamping device for shaft parts also includes a temperature controller, which is located below the temperature sensor and is electrically connected to the temperature sensor.

[0011] The beneficial effects are as follows: 1. Through the three electric slide rail drives and the centering design of the arc plate U-groove, it can quickly adapt to shaft parts of different diameters, improve clamping efficiency and reduce the cost of changing fixtures. The clamping effect of the three-way fixture enhances the stability of the workpiece, which is especially suitable for long shafts or high-precision machining needs.

[0012] 2. Real-time monitoring by the pressure sensor and the protective function of the soft pad ensure that the clamping force is moderate and the workpiece surface is protected from damage, thus improving the processing quality.

[0013] 3. The coordinated operation of the temperature sensor and controller effectively prevents thermal deformation, further improving machining accuracy. Overall automated operation simplifies the adjustment process, significantly improves production efficiency, and meets the requirements of modern high-efficiency machining.

[0020] A high-precision automatic centering and clamping device for shaft parts, see [link / reference] Figures 1-5The system includes a mounting base 1, a worktable 2, electric slide rails 3, sliders 4, a mounting plate 5, clamps 6, an arc plate 7, a pressure sensor 9, a soft pad 10, a three-way clamp 11, a temperature sensor 12, and a temperature controller 13. The mounting base 1 is fixed in the mounting position, the worktable 2 is fixed to the mounting base 1, the three electric slide rails 3 are symmetrically fixed to the mounting base 1, the sliders 4 are installed inside the electric slide rails 3, the mounting plate 5 is located on top of the sliders 4, the clamps 6 are located at the end of the mounting plate 5, and the pressure sensor 9 is located inside the clamps 6. The pressure sensor 9 is used to detect the clamping force. The three sliders 4... Arc plates 7 are connected to each other on the side that are close to each other. One end of the arc plate 7 has a U-shaped groove 8. One end of the arc plate 7 is inserted into the U-shaped groove 8 of the adjacent arc plate 7. The high-precision shaft parts automatic centering and clamping device also includes a soft pad 10. The soft pad 10, which prevents damage to the workpiece, is set outside the pressure sensor 9. The three-way clamp 11 is installed at the center of the mounting base 1. The temperature sensor 12 is installed on the worktable 2. The temperature sensor 12 is located between the three electric slide rails 3. The temperature controller 13 is set below the temperature sensor 12. The temperature controller 13 is electrically connected to the temperature sensor 12.

[0021] When using the high-precision automatic centering and clamping device for shaft parts, the operator first places the shaft part to be processed in the center area of ​​the mounting base 1, ensuring that the workpiece is roughly within the clamping range of the three-way clamp 11. Then, the device is started, and the device enters the working state. The three electric slide rails 3 start simultaneously, driving the slider 4 to move slowly inward. The mounting plate 5 on the top of the slider 4 moves accordingly, causing the clamping block 6 at the end of the mounting plate 5 to gradually approach the workpiece. After the clamping block 6 contacts the workpiece, the arc plate 7 assists in centering the workpiece, ensuring that the workpiece is accurately positioned during clamping and preventing displacement. During the clamping process, the pressure sensor 9 inside the clamping block 6 displays the clamping force value in real time. The operator can observe and adjust the pressure of the electric slide rail 3 through the control panel to ensure that the clamping force is sufficient to fix the workpiece without being too large and causing workpiece deformation. At the same time, the soft pad 10 on the outside of the clamping block 6 is in direct contact with the workpiece surface to avoid scratching or damaging the workpiece surface during clamping. If the workpiece is long or requires higher stability, the operator can adjust the three-way clamp 11 to control the three-way clamp 11 to expand outward from the center, further fixing the workpiece from three directions to prevent shaking during processing.

[0022] During processing, the temperature sensor 12 continuously monitors the temperature around the device. If the temperature rises, it may cause thermal deformation of the workpiece. The temperature controller 13 will automatically activate cooling measures (such as a fan or coolant circulation) to maintain the temperature within the set range. After processing is completed, the electric slide rail 3 drives the slider 4 to move outward, the clamping block 6 releases the workpiece, and the three-way clamp 11 also resets at the same time, allowing the workpiece to be easily removed, thus completing the entire clamping and processing process.
