Detailed Implementation

[0039] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0040] Please refer to Figures 1-7 This invention provides an embodiment of a fixed shaft boring and clamping device for offshore wind power, comprising two support seats 1 distributed along a first direction, a placement groove 11 provided on the support seat 1, the width direction of the placement groove 11 being perpendicular to the first direction, the fixed shaft 5 being conveniently placed in the placement groove 11 by means of hoisting, and the wing 51 of the fixed shaft 5 being located outside the placement groove 11.

[0041] The clamping mechanism includes a pressure rod 2, a lifting assembly 21, and a rotating assembly 22. The pressure rod 2 is located above the support base 1. After the fixed shaft 5 is placed in the placement slot 11, the lifting assembly 21 can drive the pressure rod 2 to rise and fall, thus clamping the fixed shaft 5. When the fixed shaft 5 is placed, the rotating assembly 22 can drive the pressure rod 2 to rotate, thus preventing interference in the clamping mechanism.

[0042] The locking mechanism is located at one end of the support base 1 along the first direction. When the fixed shaft 5 is placed, the locking mechanism is located at the end away from the wing 51 of the fixed shaft 5. The locking mechanism includes a pressing part 3, which is located above the groove surface of the placement groove 11. The pressing part 3 can move along the direction close to or away from the groove surface of the placement groove 11. When the fixed shaft 5 is placed in the placement groove 11, the pressing part 3 descends to press the fixed shaft 5 and prevent the fixed shaft 5 from tilting backward.

[0043] Two rotating adjustment mechanisms are located on both sides of the support base 1. When the fixed shaft 5 is placed, the rotating adjustment mechanism is located near the wing 51 of the fixed shaft 5. The rotating adjustment mechanism includes a lifting block 41 and a pressing plate 42. The lifting block 41 is connected to a lifting assembly 43 that drives it to move in the vertical direction. The lifting block 41 can support the fixed shaft 5 from below the wing 51. The pressing plate 42 is located above the lifting block 41. The pressing plate 42 is connected to a pressing assembly that drives it to rotate. It can rotate to the side of the wing 51 and press down to press the fixed shaft 5.

[0044] In other embodiments, the number of support bases 1 may also be set to other values, as long as they can stably support the fixed shaft 5.

[0045] It should be noted that this utility model should also include a controller, which is connected to the lifting component 21, the rotating component 22, the lifting component 43 and the pressing component respectively. The controller can orderly control the lifting component 21, the rotating component 22, the lifting component 43 and the pressing component, as well as the switch and working intensity, and can automatically press the fixed shaft 5. Specifically, the controller is preferably set as a PLC.

[0046] Furthermore, this utility model should also include a height difference detection component, which is connected to the controller; specifically, the height difference detection component is set as a machine tool probe. When the fixed shaft 5 is placed in the placement slot 11, the machine tool probe can automatically detect the height difference between the left and right sides of the fixed shaft 5. The controller adjusts the height of the lifting block 41 through the lifting component 43 according to the height difference information measured by the machine tool probe to ensure that the left and right heights of the fixed shaft 5 are qualified.

[0047] In this embodiment, please refer to Figure 1 and Figure 2 The two support bases 1 are connected by several stiffeners 12 to form an integrated structure. The coaxiality, straightness, parallelism and flatness of the two support bases 1 are more consistent. After the fixed shaft 5 is placed, it can play a role in quick coaxial positioning, which greatly shortens the time for finding coaxiality and alignment, improves the processing accuracy, and facilitates hoisting. At the same time, the bottom foot of the support base 1 is provided with a mounting groove 13, so that this utility model can be easily fixed and used when placed on the machine tool workbench.

[0048] Further, please refer to Figure 1 and Figure 2 The placement groove 11 is V-shaped, which can stably support the fixed shaft 5. A protective pad 16 is provided on the groove surface of the placement groove 11. The surface of the fixed shaft 5 contacts the protective pad 16, which can effectively protect the surface of the fixed shaft 5 from damage. Specifically, the protective pad 16 is fixed in the placement groove 11 by bolts. When the fixed shaft 5 rotates relative to the protective pad 16, it protects the surface of the fixed shaft 5.

[0049] In this embodiment, please refer to Figure 1 , Figure 3 and Figure 4 The clamping mechanism also includes two support rods 23, which are located below the two ends of the pressure rod 2 respectively; there are two lifting components 21, which are located between the support rods 23 and the pressure rod 2. The lifting components 21 can drive the pressure rod 2 to rise and fall by extending and retracting in the vertical direction; the rotating component 22 is located between the support rods 23 and the support base 1. The rotating component 22 drives the support rods 23 to rotate around an axis parallel to the first direction, which can drive the support rods 23 and the pressure rod 2 to rotate.

[0050] Further, please refer to Figure 1 , Figure 3 and Figure 4 The lifting assembly 21 is preferably a linear stepper motor; in other examples, the lifting assembly 21 may also be a hydraulic cylinder or an electric cylinder.

[0051] Furthermore, please refer to Figure 1 , Figure 3 and Figure 4The support rod 23 has a swing plate 24 at its bottom, and a first pin hole 241 on the swing plate 24. The support base 1 has a positioning groove 14 at the position corresponding to the swing plate 24, and a second pin hole 15 passing through the positioning groove 14. A positioning pin 25 is installed in the second pin hole 15. When the swing plate 24 is inserted into the positioning groove 14, the positioning pin 25 passes through the first pin hole 241 and the second pin hole 15 in sequence, thereby positioning the support rod 23 on the support base 1. Simultaneously, the rotating assembly 22 is a rotary cylinder connected to the positioning pin 25, and the positioning pin 25 communicates with the first pin hole 241 via... The key and keyway are matched. When it is necessary to rotate the pressure rod 2, the positioning pin 25 on the other side is removed, and the rotating cylinder drives the positioning pin 25 to rotate, which can drive the pressure rod 2 to swing. Specifically, when the rotation degree is 0°, the pressure rod 2 is in a horizontal state and the clamping mechanism is in a pressed state. When the rotation degree is 90°, the pressure rod 2 rotates to a vertical state, and the fixed shaft 5 can be easily engaged or disengaged. In other embodiments, the lifting assembly 21 can first raise the pressure rod 2 to prevent interference, and then the rotating cylinder drives the pressure rod 2 to rotate in the horizontal direction, so as to facilitate the engagement or disengagement and convenient and stable clamping of the fixed shaft 5.

[0052] For any further explanation, please refer to [link / reference]. Figure 1 , Figure 3 and Figure 4 The lower surface of the support rod 23 is provided with an inverted V-shaped groove, which can better contact the fixed shaft 5 and improve the clamping and positioning effect.

[0053] In this embodiment, please refer to Figure 1 and Figure 5 The locking mechanism includes a fixed plate 31 and a connecting plate 32. The fixed plate 31 is detachably fixed to the end face of the support base 1 along the first direction by bolts and is located below the placement groove 11. One end of the connecting plate 32 is hinged to the fixed plate 31 by a pivot, and the clamping part 3 is provided at the other end of the connecting plate 32. The connecting plate 32 can swing between a first position and a second position. In the first position, the other end of the connecting plate 32 is located above the groove surface of the placement groove 11. In the second position, the connecting plate 32 is completely located below the placement groove 11. The clamping part 3 is a clamping screw that is threadedly connected to the connecting plate 32. After the fixed shaft 5 is placed in the placement groove 11, the connecting plate 32 is rotated from the second position to the first position. Rotating the clamping screw can move it along the direction close to the groove surface of the placement groove 11 until it abuts against the fixed shaft 5, which can press the fixed shaft 5 to prevent it from tilting backward.

[0054] In this embodiment, please refer to Figure 1 and Figure 6 The rotating adjustment mechanism also includes a leveling pad 44, and the lifting block 41 and the pressing plate 42 are both located on the leveling pad 44.

[0055] Further, please refer to Figure 1 and Figure 6 The lifting component 43 is preferably configured as a rotary lifting mechanism.

[0056] Furthermore, please refer to Figure 1 and Figure 6 The clamping assembly includes a vertically arranged lead screw 45, which is connected to a rotary cylinder that drives it to rotate. The clamping plate 42 is fixed to the lead screw 45 by nuts and washers. The rotary cylinder drives the lead screw 45 to rotate, which causes the clamping plate 42 to rotate and rise and fall slightly in the vertical direction. When the left and right heights of the fixed shaft 5 are qualified, the clamping plate 42 rotates and presses down on the side of the wing 51 to clamp the fixed shaft 5.

[0057] Please refer to Figures 1-7 The specific usage of this utility model is as follows:

[0058] Based on the size of the fixed shaft 5 and the machining stroke of the machine tool, the support base 1 is installed in a suitable position on the machine tool worktable by means of hoisting, and the flatness and coaxiality of the placement slot 11 are detected by the machine tool probe.

[0059] The swing plate 24 is inserted into the positioning groove 14 and the positioning pin 25 is inserted to install the pressing mechanism onto the support base 1; the positioning pin 25 on one side is connected to the rotary cylinder to detect the lifting function of the lifting component 21 driving the pressing rod 2 and the rotation function of the rotating component 22 driving the pressing rod 2 to rotate, and the pressing rod 2 is rotated to the vertical state.

[0060] Fix the fixing plate 31 to the support base 1, thereby installing the locking mechanism device on the support base 1, and swing the connecting plate 32 between the first position and the second position to verify whether it will interfere with the placement of the fixing shaft 5.

[0061] Place the dimensions of the fixed shaft 5 and the wing 51 of the rotary adjustment mechanism on both sides of the support base 1, and check whether the lifting assembly 43 and the clamping assembly are operating normally.

[0062] The fixed shaft 5 is placed in the placement slot 11 of the support base 1 by means of hoisting. The connecting plate 32 is swung to the first position and the fixed shaft 5 is pressed down by the clamping screw to prevent the fixed shaft 5 from tilting backward.

[0063] The machine tool probe detects the left and right height difference of the fixed shaft 5. The controller controls the lifting block 41 in the rotation adjustment mechanism to rise and fall according to the feedback signal, thereby automatically adjusting the left and right heights of the fixed shaft 5 to keep them at the same height.

[0064] After the left and right height of the fixed shaft 5 is adjusted, the clamping assembly drives the clamping plate 42 to rotate and press the upper surface of the wing 51 to press the fixed shaft 5, so that the fixed shaft 5 is kept in a stable state, and the machine tool probe re-inspects the balance state of the fixed shaft 5.

[0065] After adjustment and tightening, release the locking mechanism to begin boring and milling.

[0066] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
