DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] like Figures 1 to 3 As shown, a correction structure for high-precision machining of a workpiece CNC machine tool comprises a base 1, wherein a longitudinal adjustment mechanism 2 is installed inside the base 1, wherein the longitudinal adjustment mechanism 2 comprises a first slide groove 21 provided at the center position of the upper surface of the base 1, wherein a first one-way screw 22 is rotatably connected to the inside of the first slide groove 21, wherein a first slider 23 is threadedly connected to the outer surface of the first one-way screw 22, wherein a first moving plate 24 is fixedly connected to the top of the first slider 23, and a first knob is fixedly connected to one end of the first one-way screw 22. Two first limiting grooves 25 are symmetrically provided on the upper surface of the base 1, and two first limiting blocks 26 slidably connected to the first limiting grooves 25 are symmetrically fixedly connected to the lower surface of the first moving plate 24. The first knob rotates to drive the first one-way screw 22 to rotate, and drives the first slider 23 and the first moving plate 24 to move through the thread, thereby driving the workpiece to adjust its longitudinal position.

[0024] The movable end of the longitudinal adjustment mechanism 2 is internally installed with a transverse adjustment mechanism 3, which includes a second slide groove 31 provided at the center position of the upper surface of the first movable plate 24, a second one-way screw 32 is rotatably connected to the interior of the second slide groove 31, a second slider 33 is threadedly connected to the outer surface of the second one-way screw 32, a second slider 33 is fixedly connected to the top of the second movable plate 34, the electric push rod 4 is fixedly installed on the upper surface of the second movable plate 34, and a second knob is fixedly connected to one end of the second one-way screw 32. Two second limiting grooves 35 are symmetrically provided on the upper surface of the first movable plate 24, and two second limiting blocks 36 slidably connected to the second limiting grooves 35 are symmetrically fixedly connected to the lower surface of the second movable plate 34. The rotation of the second knob drives the second one-way screw 32 to rotate, and drives the second slider 33 and the second movable plate 34 to move through the thread, so as to drive the workpiece to adjust the transverse position. By setting up the longitudinal adjustment mechanism 2 and the transverse adjustment mechanism 3, the workpiece can be finely adjusted longitudinally and transversely after being clamped, so as to achieve a high-precision adjustment effect, thereby solving the problem that the existing structure needs to adjust the position of the workpiece through movable bolts after the workpiece is fixed, and multiple movable bolts need to be turned in sequence, which is inconvenient to operate.

[0025] Embodiment 2:

[0026] like Figure 1 and Figure 4As shown, electric push rods 4 are fixedly installed on all sides of the upper surface of the movable end of the lateral adjustment mechanism 3, and a top plate 5 is fixedly connected between the top ends of the four electric push rods 4. An adjustable workpiece clamping mechanism 6 is fixedly installed on the upper surface of the top plate 5. The adjustable workpiece clamping mechanism 6 includes side plates 61 symmetrically fixedly installed on both sides of the upper surface of the top plate 5, and a cylinder 62 is fixedly installed on one side of the side plate 61. The movable end of the cylinder 62 is fixedly connected to a first clamping plate 63, and the top of the first clamping plate 63 is fixedly connected to a rectangular frame 64, and a bidirectional screw rod 65 is rotatably connected to the inside of the rectangular frame 64. The outer surface of the bidirectional screw rod 65 is symmetrically threadedly connected to two adjustment blocks 66 that are slidably connected to the inner wall of the rectangular frame 64, and the top of the adjustment block 66 is threadedly connected to a locking bolt 67, and the bottom end of the locking bolt 67 is rotatably connected to the second clamping plate, and one end of the bidirectional screw rod 65 is fixedly connected to the third knob. The operation of the two cylinders 62 can drive the first clamping plates 63 on both sides to clamp the workpiece, and the rotation of the third knob can drive the bidirectional screw 65 to rotate, which can drive the two adjustment blocks 66 and the locking bolt 67 to move relative to each other through the thread. Then, the locking bolt 67 can be rotated to press and fix the top of the workpiece, so that workpieces of different widths can be clamped, thereby solving the problem that the screw position of the existing structure is fixed and cannot be adjusted according to workpieces of different widths.

[0027] Embodiment 3:

[0028] like Figure 1 As shown, notches 7 are provided at the four corners of the upper surface of the base 1, and fixing bolts 8 are passed through the inside of the notches 7, so that the correction structure can be easily installed on the CNC machine tool through the fixing bolts 8.

[0029] Working principle: When in use, the correction structure is conveniently installed on the CNC machine tool through the fixing bolt 8, and then the workpiece is placed on the top plate 5, and then the two cylinders 62 are started. The operation of the two cylinders 62 can drive the first clamping plates 63 on both sides to clamp the workpiece, and the rotation of the third knob drives the bidirectional screw 65 to rotate, and the two adjustment blocks 66 and the locking bolt 67 are driven by the thread to move relative to each other, and then the locking bolt 67 is rotated to press and fix the top of the workpiece, so that workpieces of different widths can be clamped, thereby solving the problem that the screw position of the existing structure is fixed and cannot be adjusted according to workpieces of different widths.

[0030] Then, according to the processing position of the workpiece, the corresponding first knob and second knob are rotated. The rotation of the first knob drives the first one-way screw 22 to rotate, and the first slider 23 and the first movable plate 24 are driven to move through the thread, so that the longitudinal position of the workpiece can be adjusted. The rotation of the second knob drives the second one-way screw 32 to rotate, and the second slider 33 and the second movable plate 34 are driven to move through the thread, so that the lateral position of the workpiece can be adjusted. Through the longitudinal adjustment mechanism 2 and the lateral adjustment mechanism 3, the workpiece can be finely adjusted longitudinally and transversely after the workpiece is clamped, so as to achieve a high-precision adjustment effect, thereby solving the problem that the existing structure needs to adjust the position through movable bolts after the workpiece is fixed, and multiple movable bolts need to be rotated in sequence, which is inconvenient to operate.

[0031] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
