When the drilling is guided by the drilling jig, the drilling jig shakes and affects the drilling processing accuracy. A front cover 10 is provided at one end of the positioning portion 20, and a guide portion 30 is provided at the other end of the positioning portion 20. The guide portion 30 is used to be inserted into the positioning groove of the workpiece 200 with the positioning portion 20. The guide inclined hole 40 passes through the front cover 10, the positioning portion 20 and the guide portion 30 in sequence. After the positioning portion 20 is inserted into the positioning groove of the workpiece 200, the guide inclined hole 40 is coaxially connected with the inclined hole 210 to be processed of the workpiece 200.

[0032] In this embodiment, the material of the inclined hole processing drilling jig 100 is No. 45 steel, which is relatively cheap and has lower cost.

[0033] In this embodiment, a positioning groove is provided on the end face of the workpiece 200, and the positioning groove is connected with the inclined hole 210 to be processed inside the workpiece 200. When the inclined hole processing drilling jig 100 is inserted into the positioning groove, the inclined hole processing drilling jig 100 is positioned and matched with the positioning groove, so that the guide inclined hole 40 running through the entire inclined hole processing drilling jig 100 is connected and coaxial with the inclined hole 210 to be processed in the workpiece 200. The inclined hole processing drilling jig 100 is guided and the drilling jig tool is used to process the inclined hole 210 to be processed in the workpiece 200.

[0034] The technical solution of the utility model is to set a guide inclined hole 40 to penetrate the front cover 10, the positioning part 20 and the guide part 30, and set the positioning part 20 to cooperate with the positioning groove of the workpiece 200. When the inclined hole processing drilling jig 100 is positioned in the positioning groove of the workpiece 200 through the positioning part 20, the guide inclined hole 40 is connected and coaxial with the inclined hole 210 to be processed of the workpiece 200. When drilling the inclined hole 210 to be processed of the workpiece 200, the guiding of the guide inclined hole 40 can effectively control the angle of the inclined hole processing, thereby preventing deviation from occurring during drilling of the inclined hole, which would cause the workpiece 200 to be scrapped.

[0035] Further, it also includes a guide sleeve 80, combined with reference to Figure 3As shown, the guide sleeve 80 is embedded in the free end of the guide portion 30 and is coaxially connected with the guide inclined hole 40. In this embodiment, the free end of the guide portion 30 is provided with a mounting groove whose diameter is larger than the guide inclined hole 40, and the guide sleeve 80 is fixed in the mounting groove. After the guide sleeve 80 is installed, the inner hole of the guide sleeve 80 is connected with the guide inclined hole 40 and is coaxial. In another embodiment, the inner hole of the guide sleeve 80 is equal to the diameter of the guide inclined hole 40, so that the drilling tool can pass through smoothly.

[0036] Preferably, the free end surface of the front cover 10 is provided with a guide slope 11. Figure 4 As shown, one end opening of the guide inclined hole 40 is located at the guide inclined surface 11, and the axis of the guide inclined hole 40 is perpendicular to the guide inclined surface 11. In this embodiment, since the guide inclined surface 11 perpendicular to the axis of the guide inclined hole 40 is provided, when the guide inclined hole 40 is used to guide the inclined hole drilling process, it is convenient to position the processing tool and the guide inclined hole 40, thereby increasing the convenience of use of the inclined hole processing drilling jig 100.

[0037] Preferably, the outer periphery of the positioning portion 20 is provided with at least one positioning surface 21. Figure 1 , Figure 2 As shown, the positioning surface 21 is positioned and matched with the positioning groove wall of the workpiece 200. In this embodiment, the positioning surface 21 is a plane, and when the positioning portion 20 is inserted into the positioning groove of the workpiece 200, the positioning surface 21 abuts and matches with the positioning groove wall, thereby preventing the positioning portion 20 from deflecting during drilling, resulting in deflection between the guide inclined hole 40 and the inclined hole 210 to be processed.

[0038] Furthermore, it also includes a pin hole 60 opened on the outer periphery of the positioning portion 20, combined with reference Figure 1 , Figure 3 As shown, the pin hole 60 is provided with a pin 61 . When the positioning portion 20 is inserted into the positioning groove of the workpiece 200 , the pin 61 abuts against the wall of the positioning groove of the workpiece 200 to fix the inclined hole processing jig 100 .

[0039] In this embodiment, by setting the pin-rising hole 60, a pin-rising 61 can be set in the pin-rising hole 60. When the inclined hole processing jig 100 is positioned in the positioning groove, the pin-rising 61 abuts against the wall of the positioning groove, and the inclined hole processing jig 100 is fixed in the positioned state, thereby preventing it from shaking during use, causing the guide inclined hole 40 and the inclined hole 210 to be processed to deviate, thereby affecting the use of the inclined hole processing jig 100.

[0040] Preferably, the pin-raising hole 60 has a plurality of Figure 3As shown, a plurality of pin holes 60 are distributed at intervals on the periphery of the positioning portion 20. Specifically, when a plurality of positioning surfaces 21 are provided, a plurality of pin holes 60 can be provided, distributed on each positioning surface 21, or the pin holes 60 can be distributed on the periphery of the positioning portion 20, and the number of pin holes 60 provided on each positioning surface 21 is not limited. For this purpose, when the inclined hole processing jig 100 is processed by abutting the positioning groove wall with the pin 61, the abutting limit position can be evenly distributed.

[0041] Furthermore, it also includes a plurality of positioning matching holes 50 opened from the free end surface of the front cover 10 to the positioning portion 20, combined with reference Figure 1 , Figure 2 As shown, a threaded positioning rod 51 is installed in the internal thread of the positioning matching hole 50, and multiple positioning matching holes 50 are connected one-to-one with multiple pin holes 60, so that the threaded positioning rod 51 can lift the pin 61 to abut against the positioning groove wall of the workpiece 200.

[0042] Specifically, by screwing the threaded positioning rod 51, the threaded positioning rod 51 is made to pass through the pin hole 60 in the positioning matching hole 50, and the pin 61 extending into the positioning matching hole 50 is pushed into the pin hole 60, so that the pin 61 is limited between the threaded positioning rod 51 and the positioning groove wall, thereby realizing the fixation of the inclined hole processing drilling jig tooling 100 in the positioning groove.

[0043] Furthermore, it also includes a take-out connection hole 70 opened on the free end surface of the front cover 10, combined with reference Figure 1 , Figure 4 As shown, the take-out connection hole 70 is threadedly connected to the take-out threaded rod 71. Specifically, by setting the take-out threaded rod 71 protruding from the front cover 10, the inclined hole processing jig tool 100 can be connected to the clamping device, and the inclined hole processing jig tool 100 can be removed from the workpiece 200 by the clamping device.

[0044] Preferably, in combination with reference Figure 2 As shown, a plurality of clamping surfaces are provided at one end of the take-up threaded rod 71 away from the take-up connecting hole 70. Specifically, by providing a plurality of clamping surfaces, the clamping area of ​​the take-up threaded rod 71 can be increased, thereby facilitating the clamping of the take-up threaded rod 71 by the clamping tool.

[0045] Preferably, in combination with reference Figure 3 , Figure 4As shown, an anti-breakage wall portion 90 is provided at the connection between the positioning portion 20 and the guide portion 30, and a section of the guide inclined hole 40 located at the connection between the positioning portion 20 and the guide portion 30 is in contact with the anti-breakage wall portion 90. By providing the anti-breakage wall portion 90, a layer of thickening can be provided at the weak connection position between the positioning portion 20 and the guide portion 30, and when the guide inclined hole 40 passes through the weak connection position between the positioning portion 20 and the guide portion 30, it is prevented that the wall breaking area of ​​the inclined hole processing jig 100 is too large, resulting in the deviation of the guide inclined hole 40, and in severe cases, the workpiece 200 is damaged.

[0046] The technical solution of the utility model is to set a guide inclined hole 40 to penetrate the front cover 10, the positioning part 20 and the guide part 30, set a positioning part 20 with multiple positioning surfaces 21 with special shapes to cooperate with the positioning groove of the workpiece 200, set an anti-wall breakage part 90 at the connection between the positioning part 20 and the guide part 30, and set a guide sleeve 80 connected to the guide inclined hole 40 at the free end of the guide part 30. When the inclined hole processing drilling jig 100 is positioned in the positioning groove of the workpiece 200 through the positioning part 20, the guide inclined hole 40 is connected and coaxial with the inclined hole 210 to be processed of the workpiece 200. When drilling the inclined hole 210 to be processed of the workpiece 200, the guiding of the guide inclined hole 40 can effectively control the angle of the inclined hole processing, thereby preventing the deviation from occurring when drilling the inclined hole, which would cause the workpiece 200 to be scrapped.
