Description

Technical Field

[0001] This utility model relates to the field of clamping fixture technology, and in particular to a flange drilling fixture. Background Technology

[0002] For flanges with center holes, the majority of machining processes involve drilling bolt holes or threaded holes. During drilling, the part is usually clamped by a corresponding fixture mounted on the machine tool to perform the drilling process, thereby ensuring the accuracy of the hole and the quality of the product.

[0003] In the prior art, flanges are generally clamped and fixed by grippers. The grippers clamp the base circle of the product to achieve positioning in one direction, and then use the flange end face of the product to achieve positioning in another direction, which causes quality defects such as clamping and crushing damage to the product. Therefore, this utility model proposes a flange drilling fixture. Utility Model Content

[0004] The main objective of this invention is to provide a flange drilling fixture to solve the problems mentioned in the background art.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a flange drilling fixture includes a top plate, the top plate having a plurality of contoured material dropping holes, a support plate being vertically movable below the top plate and facing the contoured material dropping holes, the support plate being connected to a lifting assembly for driving its lifting and lowering, the upper end face of the support plate having a contoured groove, a flange being installed in the contoured groove, the flange including a body and connecting portions on both sides of the body, the body having a central hole, the connecting portions having connecting holes, the contoured groove having a clearance hole coaxial with the connecting hole, the top plate having a clearance groove hole facing the connecting portion, the centerline of the portion of the contoured material dropping holes for passing through the connecting portion intersecting the centerline of the portion of the contoured groove for accommodating the connecting portion in a horizontal plane, and the lower end face of the top plate near the periphery of the clearance groove hole abutting the upper end face of the connecting portion.

[0006] Preferably, the top plate is fixed to the base surface by multiple columns, and multiple guide rods are vertically arranged between the top plate and the base surface, with the material support plate movably connected to the guide rods.

[0007] Preferably, the lifting assembly includes top blocks vertically fixed on both sides of the lower end face of the material receiving plate. The base surface is provided with a U-shaped plate with an outward opening. The inner walls on both sides of the U-shaped plate are provided with vertical guide grooves. The top blocks are slidably connected in the guide grooves. The base surface is provided with a cylinder whose extension direction is perpendicular to the length direction of the top plate. An L-shaped push block is connected to the push rod of the cylinder. The upper end face of the horizontal part of the L-shaped push block is set as a first inclined surface with its lower end away from the vertical part of the L-shaped push block. The lower end face of the top block is set as a second inclined surface facing outward. The second inclined surface abuts against the first inclined surface.

[0008] Preferably, both the contouring blanking hole and the contouring groove have guide slopes at their openings.

[0009] The beneficial effects of this utility model are: by the cooperation of the top plate and the support plate, the flange to be processed is pressed into the contour groove on the support plate, thereby fixing the flange and facilitating subsequent drilling, thus avoiding product damage caused by clamping with a claw-type fixture in the prior art.

[0016] The present invention will be further described in detail below with reference to specific embodiments.

[0017] Example:

[0018] like Figure 1-4As shown, a flange 6 drilling fixture of this utility model includes a top plate 1, on which a plurality of contoured material dropping holes 2 are provided. A support plate 3, facing the contoured material dropping holes 2, is vertically movable below the top plate 1. A lifting assembly 4 for driving the lifting of the support plate 3 is connected to the support plate 3. A contoured groove 5 is provided on the upper surface of the support plate 3, and a flange 6 is installed in the contoured groove 5. The flange 6 includes a body and connecting portions 7 on both sides of the body. A central... Hole 8, the connecting part 7 is provided with a connecting hole 9, the contour groove 5 is provided with a clearance hole 10 coaxial with the connecting hole 9, the top plate 1 is provided with a clearance groove hole 11 facing the connecting part 7, the center line of the part of the contour dropping hole 2 that passes through the connecting part 7 intersects the center line of the part of the contour groove 5 that accommodates the connecting part 7 in the horizontal plane, and the lower end face of the top plate 1 near the periphery of the clearance groove hole 11 abuts against the upper end face of the connecting part 7.

[0019] The top plate 1 is fixed to the base surface by multiple columns 12, and multiple guide rods 13 are vertically arranged between the top plate 1 and the base surface. The material support plate 3 is movably connected to the guide rods 13.

[0020] The lifting assembly 4 includes top blocks 14 vertically fixed on both sides of the lower end face of the material support plate 3. A U-shaped plate 15 with an outward opening is provided on the base surface. The inner walls on both sides of the U-shaped plate 15 are provided with vertical guide grooves 16. The top blocks 14 are slidably connected in the guide grooves 16. A cylinder 17 with a telescopic direction perpendicular to the length direction of the top plate 1 is provided on the base surface. An L-shaped push block 18 is connected to the push rod of the cylinder 17. The upper end face of the horizontal part of the L-shaped push block 18 is set as a first inclined surface 19 with the lower end away from the vertical part of the L-shaped push block 18. The lower end face of the top block 14 is set as a second inclined surface 20 facing outward. The second inclined surface 20 abuts against the first inclined surface 19.

[0021] Both the opening of the contouring blanking hole 2 and the contouring groove 5 are provided with guide slopes.

[0022] The working process of this application is as follows: In the initial state, the support plate 3 is away from the top plate 1, and the distance between the support plate 3 and the top plate 1 is greater than the thickness of the connecting part 7 of the flange 6. The flange 6 to be processed is placed into the contouring drop hole 2, and the flange 6 falls on the support plate 3. The flange 6 is rotated until it is aligned with the contouring groove 5, and the flange 6 falls into the contouring groove 5. The push rod of the cylinder 17 extends and pushes the L-shaped push block 18 to slide inward. The first inclined surface 19 pushes the second inclined surface 20 inward, thereby driving the support plate 3 to lift the flange 6. The support plate 3 presses the flange 6 on the lower end surface of the top plate 1, thereby fixing the flange 6 in the contouring groove 5, which facilitates subsequent drilling. After processing, the cylinder 17 is reset, the support plate 3 moves away from the push rod, the flange 6 is lifted and rotated until it is aligned with the contouring drop hole 2, and the flange 6 can be taken out.

[0023] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
