Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a drilling fixture and a drilling method for the end face of an inclined cylinder. Background Art

[0002] Currently, if Figure 1 As shown, the inclined cylinder is a special structural form, in which the two end faces are not perpendicular to the axis but inclined, and the two end faces are parallel to each other.

[0003] In related technologies, such as Figure 2 As shown, when drilling the end face of the inclined cylinder 1, the vise clamping mechanism of the radial drilling machine is generally used to clamp the cylinder, and the bottom end face of the inclined cylinder 1 is attached to the vise bottom plate 4 of the vise clamping mechanism. The two vise side plates 3 of the vise clamping mechanism are clamped to the circumferential surface of the inclined cylinder 1. After clamping, the drill bit is vertically downward to drill the end face of the inclined cylinder 1.

[0004] However, since it is a column and its end face is inclined relative to the axis, the end face of the inclined column 1 after clamping it appears to be an inclined surface, and under the action of gravity, the column always has a tendency to automatically tip over (see Figure 3 ), so it is necessary to adjust several times during clamping until the end surface is level when checking with a meter (see Figure 2 ), and then drilling, the leveling process is time-consuming and laborious. Specifically, if the end face is not horizontal, the vertical drill bit is prone to breakage during drilling due to the non-perpendicularity between the drill bit and the end face, resulting in a high risk of drill bit breakage. Moreover, insufficient perpendicularity between the hole to be drilled and the end face will adversely affect subsequent assembly, resulting in poor assembly performance. Furthermore, even if the end face of the beveled cylinder is leveled, the drill bit will exert a large downward force on the beveled cylinder during drilling. The two side plates of the vise clamping mechanism are in line contact with the circumferential surface of the beveled cylinder, and line contact clamping has poor force-bearing performance. There is a risk of movement of the beveled cylinder during drilling, causing the drill bit to break.

[0005] Therefore, those skilled in the art are in urgent need of designing an auxiliary fixture specifically for drilling holes on the end face of an inclined cylinder. Summary of the Invention

[0022] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] An embodiment of the present application provides a drilling fixture for the end face of a beveled cylinder, which solves the technical problems of the traditional vise clamping mechanism clamping the beveled cylinder for drilling, such as the time-consuming and labor-intensive leveling process, the high risk of drill bit breakage, and the poor subsequent assembly performance. It ensures that the end face of the beveled cylinder 1 is in a horizontal state, and also ensures that the beveled cylinder 1 will not move when subjected to downward force during drilling.

[0024] like Figures 4 to 7 As shown, the present application discloses a drilling fixture for the end face of a beveled cylinder, the drilling fixture comprising a shell 6, a cover plate 5 and an angle adjustment mechanism 7, the top of the shell 6 is open, the shell 6 has a bottom plate and a side plate, the height of the beveled cylinder 1 is higher than the height of the shell 6, that is, when the bottom end face of the beveled cylinder 1 is in contact with the bottom plate of the shell 6, the top end of the beveled cylinder 1 extends outward from the shell 6.

[0025] The cover plate 5 is provided with external leakage holes and is bolted to the top of the housing 6 at intervals. The cover plate 5 and the base plate clamp the inclined cylinder 1. The external leakage holes reveal the portion of the inclined cylinder 1 to be drilled 2, facilitating subsequent drilling by the drill bit. Specifically, when the cover plate 5 is bolted to the housing 6, the lower end surface of the cover plate 5 directly contacts the upper surface of the inclined cylinder 1, without contacting the upper surface of the housing 6. This allows the inclined cylinder 1 to be clamped and prevented from moving up and down along the Y-axis.

[0026] The angle adjustment mechanism 7 includes an adjustment bolt 11 and a V-shaped block 8 that rotatably fits within the beveled cylinder. A peripheral structure is rotatably mounted above the V-shaped block 8. The V-shaped block 8 has a vertical V-shaped groove that supports the circumference of the beveled cylinder. The adjustment bolt 11 penetrates the peripheral structure from the outside to the inside and abuts against the beveled cylinder 1. The adjustment bolt 11 is used to adjust the tilt angle of the V-shaped block 8, ensuring that the tilt angle matches the tilt angle α of the beveled cylinder 1.

[0027] In actual use, the inclination angle of the V-shaped block 8 is first adjusted according to the known inclination angle α of the inclined cylinder 1. The inclined cylinder 1 is then placed into the V-shaped groove 14 to prevent it from rotating about the Z axis. The cover plate 5 is then bolted to the housing 6 to prevent it from moving up and down along the Y axis, thus securing the inclined cylinder 1.

[0028] The drilling fixture of the present application is clamped up and down and supported obliquely, which changes the conventional clamping method, makes the operation easier, improves the work efficiency of drilling holes on the end face of the inclined cylinder and the processing accuracy of the workpiece, and the drilling fixture of the present application is particularly suitable for the processing of multiple inclined cylinders 1 and large-scale dedicated production lines. The clamping process is easy and labor-saving, eliminates the risk of drill bit breakage, and the processed inclined cylinder 1 has good later assembly performance.

[0029] Furthermore, in one embodiment, if Figure 7 As shown, when the inclined column 1 is clamped up and down by the cover plate 5 and the bottom plate and obliquely supported by the V-shaped block 8 , the bottom end of the inclined column 1 abuts against the side plate of the housing 6 .

[0030] In the drilling fixture of the present application, the top of the inclined cylinder 1 extends outward from the housing 6, and the cover plate 5 and the bottom plate of the housing 6 clamp the inclined cylinder 1 to prevent the inclined cylinder 1 from moving up and down along the Y axis; The V-shaped block 8 provides an oblique support to prevent rotation about the Z axis and prevent the inclined cylinder 1 from moving in the positive X direction; The bottom end of the inclined column 1 is supported against the side plate of the shell 6, further preventing the inclined column 1 from moving in the negative direction of X. After the combination, the inclined column 1 can be positioned stably in all directions, ensuring that the part to be drilled 2 is horizontal and the inclined column 1 is stable. It will not move after the drilling force is applied, and the clamping is convenient and stable, thereby improving the working efficiency of drilling the end face of the inclined column 1 and the processing accuracy of the workpiece.

[0031] Specifically, the X, Y, and Z axes are shown in Figure 3 .

[0032] Furthermore, in one embodiment, the angle adjustment mechanism 7 further includes an angle ruler 13 . The angle ruler 13 is disposed on the opposite side of the V-shaped groove of the V-shaped block 8 , with the angle ruler 13 facing outward.

[0033] The angle adjustment mechanism 7 can adjust the inclination of the V-shaped block 8 to be equal to the known inclination angle of the inclined cylinder 1 through the angle ruler 13 .

[0035] The drilling fixture of the present application, the angle ruler 13 can clearly and intuitively display the inclination angle of the V-block 8, laying the foundation for precise oblique support.

[0036] Regarding the angle adjustment mechanism 7 , in one embodiment, the angle adjustment mechanism 7 includes a pin 9 , and both ends of the pin 9 are respectively fixed to two side plates of the housing 6 .

By turning the adjusting bolt 11, the inclination of the V-block 8 is adjusted to adapt to the inclination angle α of the inclined column 1.

[0038] Furthermore, a vertical strip opening is provided on the side panel of the housing 6, and an angle scale 13 is provided on the angle ruler; When adjusting the adjusting bolt 11 , the angle ruler 13 passes through the vertical strip opening, and the angle scale of the angle ruler 13 parallel to the side plate of the housing 6 represents the inclination of the V-shaped block 8 .

When adjusting the adjusting bolt 11, the angle ruler 13 passes through the vertical strip opening of the side plate. The angle scale of the angle ruler 13 parallel to the side plate of the shell 6 represents the inclination of the V-block 8. The inclination angle of the V-block 8 can be directly read from the angle ruler 13, and can be quickly adapted to the inclination angle α of the inclined cylinder 1, thereby improving the clamping efficiency and thus improving the drilling efficiency.

Specifically, positioning block 10 has a threaded hole, and the side panel of housing 6 has a circular hole slightly larger than the threaded hole. Angle ruler 13 is marked with angles. The angles on ruler 13, parallel to the outer surface of the side panel of housing 6, represent the inclination of V-block 8.

[0043] The drilling fixture of the present application, the angle ruler 13 and the adjusting bolt 11 all pass through the double-layer plate (the side plate of the shell 6 and the positioning block 10 respectively), and the structure is stable and reliable.

[0044] Preferably, the side panels of the housing 6 and the positioning blocks 10 are relatively fixed by screws.

[0045] Furthermore, corresponding to the design of the side plates and the positioning block 10 of the housing 6 of the angle adjustment mechanism 7, in another embodiment, as Figure 4 As shown, a rectangular opening groove 15 is provided on the side plate of the housing 6 , and a positioning protrusion 12 is vertically provided on the outward side of the positioning block 10 , and the positioning protrusion 12 is placed at the bottom end of the rectangular opening groove 15 .

[0046] A vertical strip opening is provided on the positioning block 10 at a position corresponding to the angle ruler 13 for the angle ruler 13 to pass through; an adjusting bolt 11 passes through the positioning block 10 and abuts against the inclined cylinder 1; The angle ruler 13 has angle scales, and the angle scales on the angle ruler 13 parallel to the outer surface of the positioning block 10 represent the inclination of the V-shaped block 8 .

[0047] The positioning block 10 of the present application is provided with a positioning protrusion 12, and the installation position of the positioning block 10 relative to the rectangular opening groove 15 is determined by the positioning protrusion 12. The angle ruler 13 and the adjusting bolt 11 both pass through the single-layer plate (that is, the positioning block 10). The angle adjustment mechanism 7 has a large placement space, which is convenient for angle adjustment and efficient clamping.

[0048] During actual use, the angle of the V-shaped block 8 of the angle adjustment mechanism 7 is first adjusted according to the inclination angle of the inclined plane column, and then the angle adjustment mechanism 7 is placed in the entire housing 6, and then the inclined plane column 1 is placed in the V-shaped groove of the V-shaped block 8 to prevent the inclined plane column 1 from rotating around the Z axis; then the cover plate 5 is fixed to the housing 6 by bolts, thereby preventing the inclined plane column 1 from moving up and down along the Y axis, so that the inclined plane column 1 can be fixed, and then the present invention is clamped with a vise and a hole is drilled on the inclined plane column 1.

[0049] Preferably, four threaded holes are provided on the top surface of the housing 6 , and the cover plates 5 are fixed to the four threaded holes one by one by four bolts, and the cover plates 5 are arranged at intervals on the top surface of the housing 6 .
