[0002] When machining products using multi-axis CNC machine tools, they must be accurately clamped. Factors such as assembly errors in the fixtures and dimensional errors in the incoming raw material can cause deviations in the product's clamping position, necessitating fine-tuning of the pitch angle during the clamping process. Existing solutions rely on manual shimming for adjustment. However, manual shimming requires repeated alignment with steel or copper sheets, resulting in low efficiency and difficulty meeting production and processing requirements. Therefore, it was necessary to develop a mechanism for fine-tuning the pitch angle. Utility Model Content

Through the description of the specific embodiments, a more in-depth and specific understanding of the technical means and effects adopted by the present invention to achieve the intended purpose can be obtained. However, the accompanying drawings are for reference and illustration purposes only and are not intended to limit the technical solutions of the present invention.

[0026] Example 1

[0027] like Figures 1 to 4 As shown, Figure 1 This is a structural diagram of an angle fine-adjustment pitch platform provided by an embodiment of the present utility model; Figure 2 This is a schematic diagram of the exploded structure of the angle fine-adjustment pitch platform provided by an embodiment of the present utility model; Figure 3 This is a partial structural cross-sectional view of the angle fine-adjustment pitch platform provided by an embodiment of the utility model; Figure 4 It is a bottom view of the structure of the angle fine-adjustment pitching platform provided by an embodiment of the utility model.

[0028] The first aspect of the present invention provides an angle fine-adjustment pitch platform, comprising: a support base 1, an angle floating plate 2, a trapezoidal slider 3 and a stud 4, wherein the support base 1 and the angle floating plate 2 are hinged by a hinge, the trapezoidal slider 3 is slid away from the hinge and is set on the support base 1, the top surface of the trapezoidal slider 3 is an inclined surface, and the inclined surface contacts the bottom surface of the angle floating plate 2; the stud 4 extends through the trapezoidal slider 3 and is threadedly connected to the support base 1.

[0029] The principle is that the support base 1 and the floating angle plate 2 are hingedly connected. A stud 4 extends through a trapezoidal slider 3 and is threadedly connected to the support base 1. Rotating the stud 4 causes the trapezoidal slider 3 to slide, pushing the floating angle plate 2 around the hinge via its inclined surface. Specifically, the sliding of the trapezoidal slider 3 changes the contact position between its inclined surface and the bottom surface of the floating angle plate 2, thereby causing the floating angle plate 2 to rotate about the hinge's axis, thereby changing the pitch angle of the floating angle plate 2.

[0030] In one optional embodiment, a receiving cavity 11 is provided at the end of the support base 1 away from the hinge, and the trapezoidal slider 3 slides within the receiving cavity 11. For example, a sliding track is provided at the bottom of the receiving cavity 11, and a protrusion is provided at the bottom of the trapezoidal slider 3 to mate with the sliding track. For ease of understanding, the end of the support base 1 away from the hinge is referred to as the first end, and the end closer to the hinge is referred to as the second end. The sliding track extends from the first end of the support base 1 toward the second end, and its extension direction is perpendicular to the hinge's rotation axis.

[0031] In an optional embodiment, a plurality of first threaded holes 12 are provided on the bottom surface of the support base 1, a plurality of first through holes 21 are provided on the angle floating plate 2, and the plurality of first threaded holes 12 are arranged in one-to-one correspondence with the plurality of first through holes 21, so that screws can be passed through the first through holes 21 and threadedly connected to the first threaded holes 12, thereby stacking and connecting two identical angle fine-tuning pitch platforms.

[0032] In an optional embodiment, a relief slope 22 is provided at the end of the angle floating plate 2 away from the hinge. The relief slope 22 contacts the slope of the trapezoidal slider 3. For example, the inclination angle of the relief slope 22 can be set to 5° to 15°. If it is too small, the adjustment sensitivity will be insufficient, while if it is too large, the structural stability will be reduced.

[0033] In an optional embodiment, the angle fine-adjustment pitch platform further includes: locking nuts 6, the stud 4 passes through two locking nuts 6 and is locked with the trapezoidal slider 3, and the cooperation of the two locking nuts 6 enables the trapezoidal slider 3 to slide under the drive of the stud 4.

[0034] In an optional embodiment, fastening screw holes 13 are symmetrically positioned on either side of the support base 1, facing away from the hinge. These holes are aligned with the hinge's axis of rotation. Accordingly, the floating plate 2 is symmetrically positioned with tabs 23 on either side, facing away from the hinge. Each tab 23 has a second threaded hole 231. Fastening screws 5 extend through these holes and thread into them. After adjusting the pitch angle of the floating plate 2 by rotating the studs 4, tighten the fastening screws 13 to lock the position of the floating plate 2.

[0035] Exemplarily, the fastening screw hole 13 can be set as a strip-shaped through hole, whose width is greater than the diameter of the second threaded hole 231, and whose length direction is set along the vertical direction. After the pitch angle of the angle floating plate 2 changes, the adjustment space of the fastening screw hole 13 is increased through the strip-shaped through hole.

[0036] It is worth noting that the angle fine-adjustment pitch platform of this embodiment is driven by the stud 4 during the adjustment process, and then transmitted by the inclined surface of the trapezoidal slider 3, so that the angle floating plate 2 only rotates around the rotation axis of the hinge. After adjustment into place, the support base 1 and the angle floating plate 2 are directly locked by tightening the screws 5 to form a rigid connection structure. The bearing capacity is improved by threaded locking, and the workpiece can be stably supported, thereby ensuring the precise fixation of the adjusted position.

[0037] The working process of the angle fine-adjustment pitching platform of the utility model is as follows:

[0038] For example, to adjust the pitch angle in the negative direction, first loosen the setscrew 5 and rotate the stud 4 counterclockwise to pull the trapezoidal slider 3 outward. The floating plate 2 now rotates about the hinge's axis, forming a negative angle with the horizontal plane. Finally, tighten the setscrew 5 to complete the negative angle adjustment. Similarly, to adjust the pitch angle in the positive direction, first loosen the setscrew 5 and rotate the stud 4 clockwise to push the trapezoidal slider 3 inward. The floating plate 2 now rotates about the hinge's axis. The inclined surface of the trapezoidal slider 3 lifts one end of the floating plate 2, causing it to move upward, forming a positive angle with the horizontal plane. Finally, tighten the setscrew 5 to complete the positive angle adjustment.

[0039] For example, the stud 4 may adopt a fine thread, such as M8×0.5 mm. One rotation of the stud 4 may cause the trapezoidal slider 3 to move 0.5 mm, corresponding to an angle change of about 0.1°.

[0040] Exemplarily, the angle adjustment range of the angle fine-adjustment pitch platform of the present invention is -1° to +2.5°.

[0041] like Figures 1 to 5 As shown, Figure 5 It is a structural schematic diagram of the angle fine-adjustment pitch device provided in an embodiment of the present utility model.

[0042] The second aspect of the present invention provides an angle fine-adjustment pitch device, including a tooling fixture 10, a tooling base plate 20 and the angle fine-adjustment pitch platform of the first aspect. Two angle fine-adjustment pitch platforms are provided, and the sliding directions of the trapezoidal sliders 3 of the two angle fine-adjustment pitch platforms are perpendicular to each other; the tooling fixture 10, the two angle fine-adjustment pitch platforms and the tooling base plate 20 are stacked in sequence from top to bottom and connected by screws.

[0043] In an optional embodiment, a plurality of second through holes 14 are provided on the support base 1 of each angle fine-adjustment pitch platform for connecting to the tooling base plate 20; a plurality of third threaded holes 24 are provided on the top surface of the angle floating plate 2 of each angle fine-adjustment pitch platform for connecting to the tooling fixture 10.

[0044] For ease of understanding, the upper fine-angle adjustment pitch platform is referred to as the first pitch platform 30, and the lower fine-angle adjustment pitch platform is referred to as the second pitch platform 40. The first and second pitch platforms 30 and 40 have identical structures and are connected integrally via screws. Specifically, the bottom surface of the floating angle plate 2 is provided with a plurality of first through-holes 21, each of which is an inverted countersunk screw hole. The bottom surface of the support base 1 is provided with a plurality of first threaded holes 12. Countersunk screws extend through the first through-holes 21 and are threadedly locked with the first threaded holes 12, thereby connecting the first and second pitch platforms 30 and 40 integrally. Furthermore, screws extend through the jig 10 and are threadedly locked with the third threaded holes 24 on the top surface of the angle floating plate 2, thereby integrally connecting the first pitch platform 30 to the jig 10 via the screws. Each of the angle-adjustable pitch platforms has multiple second through-holes 14 on its support base 1, each of which is a countersunk screw hole. Countersunk screws extend through these second through-holes 14 and are threadedly locked with the jig base 20, thus integrally connecting the second pitch platform 40 to the jig base 20. This arrangement of corresponding openings allows the jig 10, first pitch platform 30, second pitch platform 40, and jig base 20 to be internally connected, preventing interference with machining and adjustment caused by protruding screws.

[0045] It can be understood that the sliding directions of the trapezoidal sliders 3 of the first pitch platform 30 and the second pitch platform 40 are perpendicular to each other. For example, during installation, the first pitch platform 30 is rotated 90° so that the sliding directions of the trapezoidal sliders 3 of the two are perpendicular to each other, that is, the two are respectively used for pitch angle adjustment in two directions perpendicular to each other on the horizontal plane.

[0046] The working process of the angle fine-adjustment pitch device of the utility model is as follows:

[0047] First, connect and fix the tooling base plate 20 to the work surface, and then connect the first pitch platform 30 and the second pitch platform 40 in sequence. Then, clamp and fix the product on the tooling fixture 10. Determine the installation position of the product through the auxiliary visual system of the processing equipment or by using a meter. Adjust the pitch angles of the first pitch platform 30 and the second pitch platform 40 respectively, so that the product changes its pitch angle with the tooling fixture 10 until the position requirement for processing is reached. Tighten the fastening screws 5 of the first pitch platform 30 and the second pitch platform 40 respectively to complete the angle pitch adjustment.

[0048] It is understood that the angle fine-adjustment pitch device provided in the second aspect of the present invention has similar beneficial effects as the angle fine-adjustment pitch platform of the first aspect. For technical details not disclosed in the second aspect, please refer to the description of the first aspect for understanding.

[0049] This new micro-adjustable pitch platform connects a support base 1 to one end of a floating angle plate 2 via a hinge. A stud 4 drives a trapezoidal slider 3, which in turn uses the inclined surface of the slider 3 to push the other end of the floating angle plate 2, causing the floating angle plate 2 to rotate about the hinge's axis, achieving fine-tuning of the pitch angle. Bidirectional angle adjustment is achieved by rotating a single stud 4, replacing the trial-and-error adjustment process required for manual leveling. This improves workpiece clamping efficiency and enhances clamping accuracy when machining products using multi-axis CNC machine tools.
