Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a fixture for double-station hole processing of CNC equipment and a use method thereof. Background Art

[0002] In recent years, with the development of industry, the requirements for CNC equipment processing efficiency have become higher and higher, while the requirements for processing costs have become lower and lower under market competition. How to improve processing efficiency and reduce production costs while ensuring quality in production is an issue that must be considered when processing CNC equipment. In the process of hole processing of CNC equipment, how to use fixtures to clamp the processed products is the key to affecting the processing quality during product processing.

[0003] When drilling and honing the inner hole of a traditional thin plate workpiece, a chuck structure is often used to clamp and position the outer contour of the plate. This method can usually only clamp a single workpiece, and cannot achieve double-station drilling and inner hole honing. The processing efficiency is low. At the same time, the chuck structure is only convenient for clamping and processing arc-shaped workpieces. Figure 5 When the contour of the sheet workpiece shown has a special structure, the existing chuck structure is not convenient for clamping and cannot ensure stable clamping; in addition, when a thin sheet workpiece is clamped, drilled, and inner hole honed by the chuck structure, due to the thin thickness of the workpiece itself or the inconsistent thickness of the various parts of the workpiece, the chuck structure is prone to cause deformation of the sheet workpiece during clamping and drilling when clamping the outer contour of the workpiece, which greatly reduces the processing quality of the sheet workpiece, resulting in a high defective rate and low processing efficiency.

[0004] In the prior art, there is also a method of clamping and processing thin plate workpieces in the thickness direction using a pliers-type clamp. However, when the thin plate workpiece is clamped, drilled, and internal hole honed by the pliers-type clamp, this method is likely to cause damage to the clamped portion of the plate workpiece surface during the clamping action and drilling process, thereby causing the quality of the workpieces produced to decline, the defective frequency to remain high, and affecting production efficiency. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a fixture and a use method for double-station hole processing of CNC equipment. A double-station profiling plate is provided to clamp the thin plate, and the thin plate is placed in a groove structure formed by the profiling plate and matched with the contour of the thin plate to limit the movement of the thin plate in the horizontal plane. An angle cylinder is provided to fix and clamp the plate placed on the profiling plate in the vertical direction. At the same time, an adjustable elastic clamping structure is provided at the contact portion between the angle cylinder and the thin plate to achieve clamping of the thin plate while avoiding damage to the plate surface. With such a configuration, double-station processing of the thin plate can be achieved, and processing efficiency can be improved while ensuring processing quality during clamping, drilling and inner hole honing of the thin plate, avoiding damage to the plate surface, improving production yield rate and reducing production cost.

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] When drilling and honing the inner hole of a traditional thin plate workpiece, a chuck structure is often used to clamp and position the outer contour of the plate. This method can usually only clamp a single workpiece, and cannot achieve double-station drilling and inner hole honing. The processing efficiency is low. At the same time, the chuck structure is only convenient for clamping and processing arc-shaped workpieces. Figure 5 When the contour of the sheet workpiece shown has a special structure, the existing chuck structure is not convenient for clamping and cannot ensure stable clamping; in addition, when a thin sheet workpiece is clamped, drilled, and inner hole honed by the chuck structure, due to the thin thickness of the workpiece itself or the inconsistent thickness of the various parts of the workpiece, the chuck structure is prone to cause deformation of the sheet workpiece during clamping and drilling when clamping the outer contour of the workpiece, which greatly reduces the processing quality of the sheet workpiece, resulting in a high defective rate and low processing efficiency.

[0032] In the prior art, there is also a method of clamping and processing thin plate workpieces in the thickness direction using a clamp-shaped clamp, but this method is easy to cause damage to the clamped part of the plate workpiece surface during the clamping action and drilling process when the thin plate workpiece is clamped and drilled and the inner hole honing process is performed by the clamp-shaped clamp, thereby causing the quality of the produced workpiece to decrease, the defective frequency remains high, and the production efficiency is affected. To this end, the present invention provides a clamp tooling for double-station hole processing of CNC equipment and a use method.

[0033] Example 1

[0034] In a typical embodiment of the present invention, Figure 1 As shown, a fixture for double-station hole processing of CNC equipment is proposed, including a base 1, a corner cylinder 4 is provided on the base 1, and profiling plate mounting seats 2 are symmetrically provided on both sides of the corner cylinder 4, and a profiling plate 3 is provided on the profiling plate mounting seat 2 for placing a thin plate 9, and a first through hole 10 is provided on the profiling plate 3; the output end of the corner cylinder 4 is arranged away from the base 1, and a clamping structure is provided on the output end of the corner cylinder 4, and the clamping structure can be driven by the output end of the corner cylinder 4 to rotate down to approach the thin plate 9 and rotate up to move away from the thin plate 9.

[0035] In this embodiment, the base 1 is set on the supporting structure for the CNC equipment to process the thin plate 9, and the thin plate 9 is clamped by setting a double-station profiling plate 3, and the thin plate 9 is placed in a groove structure formed by the profiling plate 3 and adapted to the contour of the thin plate 9 to limit the movement of the thin plate 9 in the horizontal plane. The corner cylinder 4 is provided to fix and clamp the plate placed on the profiling plate 3 in the vertical direction, and at the same time, an adjustable elastic abutment structure is provided at the contact portion between the corner cylinder 4 and the thin plate 9 to achieve the goal of abutting the thin plate 9 while avoiding damage to the plate surface. With this arrangement, double-station processing of the thin plate 9 can be achieved, and the processing efficiency can be improved while ensuring the processing quality when clamping, drilling and inner hole honing the thin plate 9 to avoid damage to the plate surface, thereby improving the production yield and reducing the production cost.

[0036] Furthermore, the heights of the profiling plate mounting seats 2 symmetrically arranged on both sides of the corner oil cylinder 4 are consistent, and the height of the profiling plate mounting seats 2 is less than the height of the abutting structure on the output end of the corner oil cylinder 4. Such an arrangement facilitates the rotational rise and rotational fall of the corner oil cylinder 4, so that the corner oil cylinder 4 will not interfere with the profiling plate mounting seats 2 during operation. At the same time, the heights of the two profiling plate mounting seats 2 are consistent, which also facilitates the abutting structure to abut against the two profiling plates 3 at the same time, thereby improving processing efficiency.

[0037] Among them, Figure 1 and Figure 2As shown, during the rotation and ascending process of the corner oil cylinder 4, the connecting plate 5 rotates to the gap between the two profiling plate mounting seats 2, that is, the length direction of the connecting plate 5 is perpendicular to the length square of the rectangular base 1. At this time, the connecting plate 5 is away from the profiling plate mounting seat 2, which is convenient for placing the thin plate 9 into the groove structure of the profiling plate 3; when the corner oil cylinder 4 rotates and descends to press the thin plate 9, the length direction of the connecting plate 5 is parallel to the length square of the rectangular base 1, thereby realizing the pressing of the thin plate 9 in the groove structure of the profiling plate 3.

[0038] Further, such as Figure 3 and Figure 4 As shown, the top plane of the profiling plate 3 is provided with a groove structure, and the groove structure is adapted to the outer contour of the thin plate 9. In this embodiment, the thin plate 9 is a circular plate, and three convex structures of the same size are provided on the ring side of the circular plate. This structure is not convenient for clamping with a traditional chuck or clamp-shaped clamp. For this reason, a groove structure adapted to the contour of the thin plate 9 is provided on the top plane of the profiling plate 3, and the plate is placed therein to achieve the restriction of the horizontal position of the thin plate 9.

[0039] It is understandable that in other embodiments of the present invention, the groove structure of the square plate can be adaptively set according to the contour structure of other thin plates 9 to be processed to achieve position fixation of the thin plates 9.

[0040] Furthermore, the depth of the groove structure is less than the thickness of the thin plate 9. This arrangement facilitates the thin plate 9 to be taken out of the groove structure after processing. In this embodiment, the thickness of the thin plate 9 product is 2 mm, and the contoured groove structure of the contoured plate 3 sinks 1.5 mm.

[0041] Furthermore, the profiling plate 3 is detachably connected to the profiling plate mounting seat 2, and the abutting structure is detachably connected to the output end of the corner oil cylinder 4. In this way, the profiling plate 3 and the abutting structure can be set according to the specific structure of the thin plate 9, so that the fixture tooling proposed by the present invention can be assembled according to the actual processing conditions, thereby improving practicality.

[0042] Further, such as Figure 6 As shown, the abutting structure includes a connecting plate 5, which is arranged in a rectangular structure, and two ends of the connecting plate 5 are provided with second through holes 7. The output end 11 of the corner oil cylinder is connected to the middle position of the connecting plate 5.

[0043] Furthermore, when the connecting plate 5 is driven by the output end of the corner oil cylinder 4 to rotate and descend to press against the thin plate 9, the axes of the first through hole 10 and the second through hole 7 are aligned vertically.

[0044] Further, such as Figure 6 and Figure 7 As shown, a plurality of elastic structures 8 for contacting with the thin plate 9 are arranged around one side of the second through hole 7 close to the profiling plate 3 , and an end of the elastic structure 8 close to the thin plate 9 is provided with an anti-slip and wear-resistant structure.

[0045] In this embodiment, if Figure 5 As shown, the unprocessed thin plate 9 is a solid plate structure, which is placed in the groove structure of the profiling plate 3 for limiting, and the abutting structure is set as a connecting plate 5 of a rectangular structure, and the two ends of the connecting plate 5 are provided with second through holes 7. When the connecting plate 5 is driven by the output end of the corner cylinder 4 to rotate and descend to press against the thin plate 9, the axis of the first through hole 10 and the second through hole 7 are aligned up and down. At this time, the CNC equipment is used to pass through the first through hole 10, the thin plate 9, and the second through hole 7 from top to bottom in sequence to realize the drilling process of the thin plate 9. At the same time, after the drilling process is completed, the processed punching holes can also be honed by honing equipment. Such a setting can ensure the quality of the punching process on the thin plate 9 and improve the processing efficiency.

[0046] In this embodiment, three elastic structures 8 for abutting against the thin plate 9 are provided around one side of the second through hole 7 close to the profiling plate 3. The elastic structure 8 can adopt a copper sheet top screw structure, and the copper sheet is used to point contact the upper surface of the thin plate 9 to tighten the plate. The top screw structure is used to fine-tune the height of the elastic structure 8, and an anti-slip and wear-resistant structure is provided at one end of the copper sheet close to the thin plate 9 to prevent damage to the surface of the plate in tight contact when processing the thin plate 9.

[0047] Furthermore, it also includes a hydraulic control structure 6, which is arranged on the base 1 and connected to the corner oil cylinder 4. The corner oil cylinder 4 is controlled by the hydraulic control structure 6, and the pressing structure can be driven by the output end of the corner oil cylinder 4 to rotate down to press against the thin plate 9 and rotate up to move away from the thin plate 9 according to the actual processing situation, so as to better process the plate.

[0048] In a second aspect of the present invention, a method for using a fixture for double-station hole processing of a CNC device is provided, comprising:

[0049] First, according to the contour structure of the thin plate 9 to be processed, a matching profiling plate 3 is selected and installed on the profiling plate mounting seat 2;

[0050] According to the contour structure of the thin plate 9 to be processed, a matching connecting plate 5 is selected and installed on the output end of the corner cylinder 4, and a plurality of elastic structures 8 are arranged around the second through hole 7 near the side of the profiling plate 3, so that when the connecting plate 5 is driven by the output end of the corner cylinder 4 to rotate and descend to press against the thin plate 9, the axes of the first through hole 10 and the second through hole 7 are aligned up and down, and the elastic structures 8 press against the thin plate 9 at the same time;

[0051] Place the thin plate 9 in the groove structure on the contour plate 3, and operate the hydraulic control structure 6 to make the clamping structure rotate and descend under the drive of the output end of the corner cylinder 4 to clamp the thin plate 9, so as to process the thin plate 9; after the processing is completed, operate the hydraulic control structure 6 to make the clamping structure rotate and rise away from the thin plate 9 under the drive of the output end of the corner cylinder 4, and remove the processed thin plate 9.

[0052] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
