Description

Technical Field

[0001] This utility model relates to the field of rust removal equipment technology, specifically to a double-head boring tapered hole device. Background Technology

[0002] For example, Chinese Patent Publication No. CN118559072B discloses a multi-functional boring machine. This machine is equipped with a straight hole tool holder, a tapered hole tool holder, and a sealing groove tool holder. The tapered hole is machined by the engagement of a clutch assembly and a nut, and the sealing groove is machined by the disengagement of the clutch assembly and the nut. This machine can also machine the straight hole of the rudder blade using the straight hole tool holder, thus completing the overall machining of the rudder blade, resulting in high machining efficiency. However, when machining the sealing groove on the rudder blade, the first locking component must be loosened, then the connecting component must be separated from the clutch plate, then the clutch plate must be separated from the nut, and finally the sealing groove tool holder must be raised and lowered by adjusting the mounting sleeve. This operation is relatively cumbersome. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a double-head boring tapered hole device, which solves the problem of cumbersome operation when switching the machining of the sealing groove of the rudder blade.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A double-head boring machine for taper holes includes a boring bar, on which a lead screw mechanism and a tool holder are mounted. The tool holder is equipped with a straight hole tool holder, a taper hole tool holder, and a sealing groove tool holder. The lead screw mechanism includes a lead screw and a nut. The tool holder is equipped with a nut seat for circumferentially engaging with the nut. The machine also includes:

[0006] The roller is located on the bottom surface of the sealing groove tool holder;

[0007] A feed cam bar is used to connect with a nut, and the top surface of the feed cam bar is provided with an inclined surface for cooperating with a roller;

[0008] A limiting plate is provided on the nut seat, and the limiting plate is located on the left and right sides of the feed cam bar;

[0009] A locking element is provided on at least one limiting plate and is used to cooperate with the feed cam bar.

[0010] The locking component is a bolt, which is installed on two limiting plates and used to tighten the feed cam strip.

[0011] The tool holder is provided with a guide seat for installing the sealing groove tool holder, and both the guide seat and the sealing groove tool holder are provided with a scale.

[0012] A copper sleeve is provided between the nut seat and the nut.

[0013] There are two tapered hole tool holders, symmetrically arranged on the left and right sides of the tool holder. The sealing groove tool holder is located at the upper end of the tool holder, and the straight hole tool holder is located at the lower end of the tool holder.

[0014] It also includes a guide rail that is inclined on the boring bar, a slider for mounting a tapered hole tool holder on the guide rail, a through groove on the tool holder, the size of the through groove matching the size of the slider, and the slider located in the through groove.

[0015] The tool holder is integrally formed.

[0016] The beneficial effects of this utility model are:

[0017] When machining tapered holes, the locking element engages with the feed cam, which in turn connects the nut to the tool holder. Rotating the lead screw moves the tool holder via the nut. When machining sealing grooves, the locking element disengages from the feed cam, and rotating the lead screw moves the feed cam relative to the tool holder via the nut. The top surface of the feed cam is used to raise and lower the sealing groove tool holder. This equipment only requires the locking element to disengage or engage with the feed cam, making the operation simple and convenient when switching between sealing groove machining.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] In the embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a double-head boring machine for conical holes includes a boring bar 1, on which a lead screw mechanism and a tool holder 2 are mounted. The tool holder 2 is equipped with a straight hole tool holder 3, a conical hole tool holder 4, and a sealing groove tool holder 5. The lead screw mechanism includes a lead screw 6 and a nut 7. The tool holder 2 is equipped with a nut seat 8 for circumferentially engaging with the nut 7. The machine also includes:

[0029] Roller 9 is set on the bottom surface of the sealing groove knife holder 5;

[0030] The feed cam 10 is used to connect with the nut 7, and the top surface of the feed cam 10 is provided with an inclined surface for cooperating with the roller 9;

[0031] A limiting plate 11 is provided on the nut seat 8, and the limiting plate 11 is located on the left and right sides of the feed cam bar 10;

[0032] Locking element 12 is disposed on at least one limiting plate 11 and is used to cooperate with feed cam bar 10.

[0033] When tapered hole machining is required, the locking element 12 engages with the feed cam 10, thereby connecting the nut to the tool holder 2. Rotating the lead screw 6 drives the tool holder 2 to move via the nut 7. When sealing groove machining is required, the locking element 12 disengages from the feed cam 10. Rotating the lead screw 6 drives the feed cam 10 to move relative to the tool holder 2 via the nut 7. The top surface of the feed cam 10 is used to raise and lower the sealing groove tool holder 5. This equipment only requires the locking element 12 to disengage or engage with the feed cam 10 to achieve this. When switching between sealing groove machining, the operation is simple and convenient.

[0034] In the embodiments, such as Figure 2 , Figure 3 , Figure 7As shown, the locking element 12 is a bolt, which is installed on two limiting plates 11 and used to tighten the feed cam strip 10. By tightening the feed cam strip 10 on both sides with the bolt, the feed cam strip 10 moves together with the tool holder 2; loosening the bolt allows the feed cam strip 10 to move relative to the tool holder 2, making adjustment simple and convenient.

[0035] In the embodiments, such as Figure 2 , Figure 3 As shown, the tool holder 2 is provided with a guide seat 18 for mounting the sealing groove tool holder 5. Both the guide seat 18 and the sealing groove tool holder 5 are provided with a scale 13. The lifting distance of the sealing groove tool holder 5 can be accurately measured through the scale 13, which facilitates the precise machining of the sealing groove depth.

[0036] In the embodiments, such as Figure 2 , Figure 3 , Figure 5 As shown, a copper sleeve 14 is provided between the nut seat 8 and the nut 7. This reduces the friction between the nut seat 8 and the nut 7, facilitating the movement of the nut 7 relative to the nut seat 8.

[0037] In the embodiments, such as Figure 2 As shown, there are two tapered hole tool holders 4, symmetrically arranged on the left and right sides of the tool holder 2. The sealing groove tool holder 5 is located at the upper end of the tool holder 2, and the straight hole tool holder 3 is located at the lower end of the tool holder 2. When machining tapered holes, a single tapered hole tool holder 4 may cause the boring bar 1 to be subjected to force on one side, which may lead to deformation of the boring bar 1 and thus affect the machining accuracy. The symmetrical arrangement of the tapered hole tool holders 4 ensures that the boring bar 1 is subjected to force evenly, thereby ensuring machining accuracy.

[0038] In the embodiments, such as Figure 2 , Figure 8 As shown, it also includes a guide rail 15 inclined on the boring bar 1, on which a slider 16 for mounting the tapered hole tool holder 4 is provided. The tool holder 2 has a through groove 17, the size of which matches the size of the slider 16, and the slider 16 is located within the through groove 17. When the tapered hole tool holder 4 is subjected to force, the slider 16 within the through groove 17 will not shift left or right, ensuring the machining accuracy of the tapered hole.

[0039] In the embodiments, such as Figure 2 As shown, the tool holder 2 is integrally formed. The tool holder 2 has good overall stability, ensuring the machining accuracy of the rudder blade.

[0040] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
