[0002] In daily production and processing, it is often necessary to drill holes on cylindrical surfaces with large curvatures. If a drill is used directly to drill holes on CNC boring and milling machines, machining centers and other equipment, the curved surface will give the drill bit a radial component of force on the cross-edge, causing the drill tip to easily slip and deviate from the original axis during the drill bit cutting into the workpiece, which not only affects the processing quality of the hole, but also often causes the drill bit to break. If drilling jig processing is used, it will not only improve the processing efficiency, but also release the production capacity of CNC equipment.

[0003] Conventional drilling jigs can only process workpieces of one specification length and diameter, which will result in high processing costs and cumbersome use. There is currently no effective solution to the above problems. Summary of the invention

[0007] Further optionally, an end of the adjusting screw away from the workpiece to be processed is provided with an anti-slip pattern.

[0008] Further optionally, there are two fixing screws, and the two fixing screws respectively pass through positions near both ends of the fixing pressure plate and are threadedly connected to the top of the base.

[0009] Further optionally, a first positioning hole is opened at the edge of the groove; second positioning holes are evenly distributed on the circumference of the adjustable mold body close to the outer edge; and a positioning pin is used to insert into the first positioning hole and the second positioning hole when the center of the first positioning hole is coaxial with the center of the second positioning hole.

[0010] Further optionally, there are multiple centers of guide holes on the line between the center of each second positioning hole and the center of the adjustable mold body, and the center of each line corresponds to a guide hole of multiple diameters.

[0011] Further optionally, the positioning sleeve is interference fit with the mounting hole.

[0012] Further optionally, the device also includes a drill sleeve, which is used to be installed in the guide hole after the guide hole is determined.

A groove 601 is also formed on one side of the base 6 for mounting the adjustable mold body 5.

[0033] Figure 3 It is a schematic diagram of the structure of the workpiece 3 to be processed provided by the prior art, such as Figure 3 As shown, the workpiece body is cylindrical, and a hole needs to be made in the side wall of the cylindrical body, that is, a processing hole 301. For this purpose, the present embodiment is provided with a positioning sleeve 4, as shown in FIG. Figure 4 , Figure 5 As shown, there are two mounting sleeves, which are respectively inserted into the top mounting hole and the bottom mounting hole of the base 6 . Figure 6 is a schematic diagram of the structure of the positioning sleeve provided by an embodiment of the present invention, such as Figure 6 As shown, the end of each positioning sleeve 4 is provided with a folded edge protruding outward, which is used to be stuck on the edge of the mounting hole 602, so as to facilitate installation and extraction. The size of the mounting sleeve can be adjusted according to the size of the workpiece 3 to be processed, ensuring that the outer wall of the positioning sleeve 4 and the mounting hole 602 are interference-fitted, and the inner diameter of the positioning sleeve 4 is adapted to the outer diameter of the workpiece 3 to be processed.

[0034] Figure 7 is a schematic diagram of the structure of an adjustable phantom provided in an embodiment of the present invention, such as Figure 7 As shown, the adjustable mold body 5 is generally circular, and is covered with guide holes 502. The guide holes 502 are of different sizes and are made according to the hole processing requirements of different types of workpieces 3 to be processed. Figure 1 It can be seen that the adjustable mold body 5 is adapted to the groove 601 and can be rotatably installed in the groove 601 . When the adjustable mold body 5 is installed in place, the outer surface of the adjustable mold body 5 is flush with the side surface of the base 6 .

[0035] Figure 8 is a side sectional view of an adjustable multi-hole drilling template device provided by an embodiment of the present invention, such as Figure 8As shown, before processing, the adjustable mold body 5 is first installed in the groove 601, and the two positioning sleeves 4 are installed in the mounting holes 602 at the top and bottom of the base 6. At this time, the workpiece 3 to be processed is installed from the top positioning sleeve 4, and according to the position to be punched of the workpiece 3 to be processed, the adjustable mold body 5 is rotated until the guide hole 502 of the corresponding size is rotated to the position to be punched, and the guide hole 502 is used for the punching operation.

[0036] As an optional embodiment, the device also includes: a fixed pressure plate 2, which is connected to the top of the base 6 through a fixed screw 7, and the fixed screw 7 is threadedly connected to the top of the base 6; an adjusting screw 1, which passes through the fixed pressure plate 2 and is threadedly connected to the fixed pressure plate 2, and one end of the adjusting screw 1 is in contact with the workpiece 3 to be processed.

[0037] like Figure 1 , Fig. 9 As shown, the top of the base 6 is also provided with a fixed platen 2, a fixed screw 7 and an adjusting screw 1. The fixed platen 2 is connected to the top of the base 6 by the fixed screw 7 and is at a certain distance from the top of the base 6. The fixed screw 7 passes through the fixed platen 2 and is threadedly connected to the top of the base 6, so that the distance between the fixed platen 2 and the top of the base 6 can be adjusted by rotating the fixed screw 7. In addition, the adjusting screw 1 passes through the fixed platen 2 and is threadedly connected to the fixed platen 2, and the end of the adjusting screw 1 contacts the end of the workpiece 3 to be processed. When the adjusting screw 1 is rotated, the degree of compression of the workpiece 3 to be processed can be adjusted. For different models of workpieces 3 to be processed, the degree of compression of the workpiece 3 to be processed can be ensured by adjusting the fixed screw 7 and the adjusting screw 1, so as to avoid the workpiece 3 to be processed rotating under the action of the drilling force during drilling, thereby affecting the drilling accuracy.

[0038] As an optional implementation, Fig.10 As shown, an end of the adjusting screw 1 away from the workpiece 3 to be processed is provided with an anti-slip pattern 101 .

When the position to be punched of the workpiece 3 to be processed is determined, the corresponding guide hole 502 is rotated to the position to be punched. At this time, the center of a second positioning hole 501 is coaxial with the center of the first positioning hole 603, and the two are connected by the positioning pin 8 to ensure the relative position of the adjustable mold body 5 and the base 6, and at the same time ensure that the guide hole 502 will not move, thereby ensuring the accuracy of the final punching.

[0044] As an optional implementation, there are multiple centers of guide holes 502 on the line between the center of each second positioning hole 501 and the center of the adjustable mold body 5, and the center of each line corresponds to a guide hole 502 of multiple diameters.

[0045] like Fig.11 As shown, a virtual line is formed between the center of each second positioning hole 501 and the center of the adjustable mold body 5, and the centers of multiple guide holes 502 are arranged on the line. The diameters of the guide holes 502 on each line are not the same, and the number, diameter and arrangement of the guide holes 502 on different lines are not the same, and can actually be set according to the actual workpiece model.

[0046] As an optional implementation, the positioning sleeve 4 is interference fit with the mounting hole 602 .

[0047] The positioning sleeve 4 is interference-fitted with the corresponding mounting hole 602 to ensure the tightness of the installation and avoid the problem that the workpiece 3 to be processed rotates in the mounting hole 602 along with the positioning sleeve 4, thereby ensuring the final processing accuracy.

[0048] As an optional implementation, the drill sleeve 9 is used to determine the guide hole 502 and then be installed in the guide hole 502 .

[0049] After the guide hole 502 is selected, the drill sleeve 9 is placed in the guide hole 502 and then the drilling process is performed.

[0050] As an optional embodiment, a plurality of drill sleeves 9 are provided according to different sizes of the guide holes 502 .

[0051] A plurality of drill sleeves 9 are provided according to the size of the guide hole 502 , and when guide holes 502 of different diameters are selected, corresponding drill sleeves 9 are used to assist in drilling.

[0052] The use of this device is as follows:

[0053] According to the diameter and length of the workpiece, select the appropriate positioning sleeve, and then install the two positioning sleeves into the mounting holes of the base accordingly; Figure 1 As shown, the mold body is installed in the positioning sleeve; the adjustable mold body is rotated, and the second positioning hole corresponding to the suitable guide hole is rotated to be coaxial with the first positioning hole according to the diameter and position of the hole to be punched in the workpiece to be processed, and the positioning pin is inserted to fix it, such as Figure 1 and Figure 3 As shown, at this time, the positioning dimension L of the machining hole of the workpiece to be machined is consistent with the positioning dimension L of the guide hole of the adjustable die from the reference surface; the fixing screw is passed through the fixed pressure plate and threadedly connected to the threaded hole on the top of the base; the adjusting screw is rotated until the end of the workpiece to be machined is tightened to ensure that the workpiece will not rotate at will; the corresponding drill sleeve is inserted into the selected guide hole of the adjustable die used; and drilling is performed. Among them, the reference surface is the top surface of the top positioning sleeve.

[0054] The above technical solution has the following beneficial effects:

[0055] 1. It can quickly complete the processing of drilling holes on cylindrical surfaces with large curvature, accurately position, reduce the burden on workers, release the production capacity of machine tools and equipment, speed up production progress, and improve processing efficiency and quality;
