Description

TECHNICAL FIELD

[0001] The application relates to the technical field of gear box boring, and particularly relates to a gear boring equipment for gear box production and machining. BACKGROUND

[0002] Boring is a kind of internal diameter cutting process for expanding a hole or other circular profile by using a tool, and the application range is generally from semi-rough machining to finish machining, and a single-blade boring tool is usually used. On a numerical control machine tool, a non-standard tool (eccentric boring tool, rotating blade and special counter-boring tool) is often used to perform counter-boring machining by using a numerical control adding engineering formula. The single-blade boring tool is rotated to expand a preformed hole on a workpiece to a certain size, so that the hole reaches the required precision and surface roughness. Boring is generally performed on a boring machine, a machining center and a combined machine tool, and is mainly used for machining cylindrical holes, threaded holes, hole grooves and end faces on box bodies, supports and machine bases and the like. When special accessories are used, internal and external spherical surfaces, taper holes and the like can also be machined.

[0003] During boring, the workpiece is installed on a machine tool worktable or a machine tool clamp, and the boring tool is clamped on a boring bar and rotated by a main shaft. When a boring die is used, the boring bar is floatingly connected with the main shaft, and the machining precision depends on the precision of the boring die. When the boring die is not used, the boring bar is rigidly connected with the main shaft, and the machining precision depends on the precision of the machine tool.

[0004] Gear boxes have a wide range of applications and have the following functions: 1. acceleration and deceleration (such as a variable speed gear box); 2. changing the transmission direction (for example, two sector gears can be used to vertically transmit force to another rotating shaft); 3. changing the rotating torque (under the condition of the same power, the faster the speed of the gear, the smaller the torque on the shaft, and vice versa); 4. clutch function (by separating two gears that are originally engaged, the engine and the load are separated. For example, a brake clutch); 5. power distribution (for example, using a single engine, a plurality of slave shafts are driven by the gear box main shaft, so that a single engine can drive multiple loads).

[0005] During the production process of the gear box, a boring device is often used to open a cylindrical groove in the gear box, so as to install and work the gear and related parts.

[0006] The patent file with the publication number CN116765448B is a gear machining boring equipment which can effectively improve the boring efficiency of the gear by using a plurality of boring tools arranged in an annular array to boring the gear hole position synchronously and on the same division circle. Meanwhile, by using the relative movement of the wedge-shaped structure, the distance between each boring tool and the rotating axis can be adjusted synchronously, so as to adjust the boring size after each retraction and then feeding, and realize the boring of the gear hole diameter from small to large.

[0007] Meanwhile, by setting the outer limiting structure, when the sleeve body can rotate relative to the cylindrical body, since the polygonal cavity is in a spatial fixed state and cannot rotate, at this time, the No. 3 triangular block located at the wedge-shaped structure part will move away from the center line direction of the cylindrical body, thereby increasing the turning size of the boring cutter, and realizing the turning size requirement from small to large required by boring, when the sleeve body rotates reversely, due to the limiting of the No. 1 triangular block and the No. 2 triangular block, it cannot rotate, thereby realizing the adjustment function of the boring cutter during rotation.

[0008] However, in the process of implementing the above technical solutions, it is found that the above technical solutions have the following technical problems:

[0009] The gear machining boring equipment synchronously bores the boring hole part of the gear on the same index circle by using the boring cutters arranged in a plurality of annular arrays, and the relative motion of the wedge-shaped structure can synchronously adjust the distance between each boring cutter and the rotation axis, thereby adjusting the boring size after each retraction and then feeding, and for a gear box, there may be a large boring radius difference between the spaces that need to be bored, although the equipment can synchronously adjust the distance between each boring cutter and the rotation axis, in actual application, the adjustable distance is limited, and it is difficult to realize the boring work of multiple spaces with a large radius difference in the gear box, and the limitation is large. SUMMARY

[0010] In order to overcome the defects that the existing gear machining boring equipment can synchronously adjust the distance between each boring cutter and the rotation axis, but in actual application, due to the large boring radius difference between the spaces that need to be bored in the gear box, the adjustable distance of the equipment is limited, and it is difficult to realize the boring work of multiple spaces with a large radius difference in the gear box, and the limitation is large, the embodiments of the present application provide a gear boring equipment for gear box production and processing, which pushes the first pressure plate by using a hydraulic push rod, first presses the long rod by using a tension spring, makes the long rod push the U-shaped frame to press the connecting rod by means of the first limiting disc and the second limiting disc on the long rod, makes the boring cutter head extend to the limit position from the inside of the boring arm, then the first pressure plate continues to slide outside the long rod, stretches the tension spring to press the first drive plate by the first pressure plate, can make the first drive plate push the rail to drive the adapter relative to the support to move in the direction of the boring cutter head, realizes the change from coaxial to different shafts of the boring arm and the drive shaft, which is beneficial to increase the boring length of the boring cutter head in the gear box and expand the boring space.

[0011] The technical solutions adopted by the embodiments of the present application to solve the technical problems are as follows:

[0012] A gear boring machine for gearbox manufacturing includes a boring head structure applied to the machine, comprising a boring arm and a drive shaft. The end of the drive shaft away from the boring arm is connected to a motor on the boring machine. An adapter seat is provided at the end of the boring arm near the drive shaft. A limiting trapezoidal block is integrally formed on the surface of the adapter seat. A support seat is integrally formed at the end of the drive shaft near the boring arm. A boring head is provided inside the end of the boring arm away from the drive shaft.

[0013] A bipolar control structure is provided between the drive shaft and the boring arm. The bipolar control structure includes a second drive plate. A connecting rod is threadedly connected to the bottom of the second drive plate near the drive shaft. A U-shaped frame is fixed to one end of the connecting rod by a nut. A long rod is provided inside the U-shaped frame. A second pressure plate is threadedly connected to one end of the long rod. A first pressure plate is provided on one side of the top of the second pressure plate. A tension spring is provided between the tops of the first and second pressure plates. A hydraulic push rod is assembled and connected to the bottom of the first pressure plate facing the second pressure plate. The first drive plate is slidably connected to the outside of the long rod.

[0014] The boring head is driven by a bipolar control structure between the drive shaft and the boring arm. It first extends out of the boring arm from the inside of the boring arm in a direction perpendicular to the axis of the boring arm. Then, the bipolar control structure drives the adapter to move outside the limiting trapezoidal block in the direction of the boring head's movement.

[0015] In one possible implementation, the boring arm has a tool head limiting groove and a tool head receiving groove inside the end away from the drive shaft. A trapezoidal plate is integrally formed on one side of the top of the boring tool head. A corner groove is formed inside the bottom of the second drive plate near one corner of the boring tool head. The cross-section of the corner groove is an isosceles right triangle. The thickness of the tool head limiting groove is greater than the thickness of the tool head receiving groove. The inclined surface of the trapezoidal plate is adapted to the top inner wall of the corner groove. The boring tool head is slidably connected inside the tool head limiting groove. The second drive plate is slidably connected to the outside of the trapezoidal plate through the corner groove.

[0016] In one possible implementation, the second drive plate has a strip groove parallel to the inclined surface of the trapezoidal plate inside, and a limit rod is pin-connected to the bottom of the trapezoidal plate at one corner away from the boring head; the inside of the strip groove is connected to the inside of the corner groove, and the limit rod is slidably connected inside the strip groove.

[0017] In one possible implementation, a guide rod is provided at the top of the long rod on one side of the U-shaped frame, and a first limiting plate and a second limiting plate are provided at the end of the guide rod and the long rod near the U-shaped frame; the first limiting plate and the second limiting plate are respectively located on both sides of the U-shaped frame, and the guide rod and the long rod are both located at the top of the plane where the connecting rod is located.

[0018] In one possible implementation, the inner side of the bottom of the limiting trapezoidal block is provided with a track bar connected to the adapter seat, the bottom of the first drive plate is provided with a track groove, and the guide rod is externally sleeved with a spring; the first drive plate is slidably connected to the outside of the track bar through the track groove, and the spring is supported between the first drive plate and the second limiting plate on the guide rod.

[0019] In one possible implementation, the boring arm has an integrally formed base plate at one end near the drive shaft, a first movable slot is provided on the top of the boring arm at the end near the drive shaft, and a second movable slot is provided on the top of the support base; the base plate is assembled to the surface of the support base away from the track bar, and the U-shaped frame is movably connected inside the second movable slot and the first movable slot.

[0020] In one possible implementation, a receiving groove is provided at the bottom of the drive shaft near the boring arm end, and limiting ribs are integrally formed on both inner walls of the receiving groove. Limiting grooves are provided on both surfaces of the first drive plate. The limiting ribs are adapted to be connected inside the limiting grooves, and the first drive plate is slidably connected between the two limiting ribs through the two limiting grooves.

[0021] In one possible implementation, hooks are welded to the top surfaces of both the first and second pressure plates facing each other, and the two ends of the tension spring are respectively sleeved onto the outside of the two hooks.

[0022] In one possible implementation, a back plate is welded to the inner wall of the receiving groove at the end away from the boring arm, and the end of the hydraulic push rod away from the first pressure plate is fitted to the surface of the back plate.

[0023] In one possible implementation, the inclination of the track groove is the same as the inclination direction and angle of the inclined surface on the trapezoidal plate. The first pressure plate is pushed by a hydraulic push rod, and the second pressure plate is driven by a tension spring to first apply pressure to the long rod. The long rod pushes the U-shaped frame to apply pressure to the connecting rod with the first and second limiting plates on it. The second drive plate applies pressure to the trapezoidal plate through the corner groove, so that the boring head extends out from the inside of the boring arm. Then the tension spring is stretched so that the first pressure plate continues to apply pressure to the first drive plate, so that the first drive plate pushes the track bar to drive the adapter seat to move relative to the support seat in the direction of the boring head.

[0024] The beneficial effects of this application are as follows:

[0025] Firstly, in this solution, the first pressure plate is controlled to move towards the boring arm by a hydraulic push rod. The second pressure plate is driven by a tension spring to apply pressure to the long rod. The long rod pushes the U-shaped frame to apply pressure to the connecting rod with the help of the first and second limiting plates. When the second drive plate applies pressure to the trapezoidal plate through the corner groove, the inclined inner wall of the corner groove applies pressure to the inclined surface on the trapezoidal plate. The trapezoidal plate drives the boring head to move inside the tool head limiting groove inside the tool head receiving groove, so that the boring edge on the boring head extends out from inside the boring arm. When the boring equipment works and drives the drive shaft to rotate at one end connected to the motor on the boring equipment, the boring head can be driven by the drive shaft and the boring arm to process spaces of different diameters inside the gearbox to be processed.

[0026] Secondly, in this solution, a hydraulic push rod is used to push the first pressure plate, and a tension spring is used to drive the second pressure plate to apply pressure to the long rod. The long rod, with the help of the first and second limiting plates, pushes the U-shaped frame to apply pressure to the connecting rod. The second drive plate applies pressure to the trapezoidal plate through the corner groove. After the boring head extends from the inside of the boring arm to the limit position, the first pressure plate continues to slide on the outside of the long rod. The tension spring is stretched to make the first pressure plate apply pressure to the first drive plate. This allows the first drive plate to push the track bar to drive the adapter seat to move relative to the support seat in the direction of the boring head. This realizes the change of the boring arm and the drive shaft from coaxial to non-coaxial, which is beneficial to increase the length of the boring head boring inside the gearbox and expand the boring space.

[0027] Thirdly, in this solution, by utilizing a bipolar control structure to operate between the drive shaft and the boring arm, the second drive plate can apply pressure to the trapezoidal plate, causing the boring head to extend from the inside of the head limiting groove. The first drive plate can also apply pressure to the track strip on the adapter, causing the adapter to drive the boring arm to move in the direction of the boring head. This facilitates the bipolar control of the boring head and the adapter by the same control component, resulting in better overall linkage and simplifying the control structure.

[0039] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0040] Example 1:

[0041] This embodiment describes the specific structure of a gear boring machine used in gearbox manufacturing. See details below. Figures 1-9As shown, the device includes a boring head structure, which includes a boring arm 4 and a drive shaft 1. A transition seat 3 is provided at one end of the boring arm 4 near the drive shaft 1. A limit trapezoidal block 7 is integrally formed on the surface of the transition seat 3. A support seat 2 is integrally formed at one end of the drive shaft 1 near the boring arm 4. A boring head 5 is provided inside the end of the boring arm 4 away from the drive shaft 1.

[0042] A bipolar control structure is provided between the drive shaft 1 and the boring arm 4. The bipolar control structure includes a second drive plate 15. A connecting rod 14 is threadedly connected to the bottom of the second drive plate 15 near the drive shaft 1. A U-shaped frame 23 is assembled and fixed to one end of the connecting rod 14 by a nut 13. A long rod 26 is provided inside the U-shaped frame 23. A second pressure plate 30 is threadedly connected to one end of the long rod 26. A first pressure plate 29 is provided on one side of the top of the second pressure plate 30. A tension spring 33 is provided between the top of the first pressure plate 29 and the second pressure plate 30. A hydraulic push rod 10 is assembled and connected to the bottom of the first pressure plate 29 facing the second pressure plate 30. A first drive plate 8 is slidably connected to the outside of the long rod 26.

[0043] The boring arm 4 has a tool head limiting groove 35 and a tool head storage groove 6 inside the end away from the drive shaft 1. A trapezoidal plate 16 is integrally formed on one side of the top of the boring tool head 5. A corner groove 18 is formed inside the bottom of the second drive plate 15 near the corner of one side of the boring tool head 5.

[0044] A guide rod 25 is provided on the top of the long rod 26 on one side of the U-shaped frame 23. A first limiting plate 21 and a second limiting plate 22 are provided on the end of the guide rod 25 and the long rod 26 near the U-shaped frame 23.

[0045] The first limiting plate 21 and the second limiting plate 22 are located on both sides of the U-shaped frame 23, and the guide short rod 25 and the long rod 26 are located at the top of the plane where the connecting rod 14 is located. When the hydraulic push rod 10 is working, the first pressure plate 29 is pushed by the hydraulic push rod 10, and the second pressure plate 30 is driven by the tension spring 33 to first apply pressure to the long rod 26, so that the long rod 26 pushes the U-shaped frame 23 to apply pressure to the connecting rod 14 with the help of the first limiting plate 21 and the second limiting plate 22 on it, so that the second drive plate 15 applies pressure to the trapezoidal plate 16 through the corner groove 18, so that the boring head 5 extends out from the inside of the boring arm 4, which is conducive to boring work inside the gearbox;

[0046] Meanwhile, the end of the drive shaft 1 away from the boring arm 4 is connected to the motor on the boring equipment. When the boring equipment is working, the boring head 5 can be driven by the drive shaft 1 and the boring arm 4 to process the target space inside the gearbox to be processed.

[0047] In addition, the overall length of the boring head 5 must be less than the smallest diameter in the boring space inside the gearbox, and the boring head 5 is allowed to protrude from the inside of the head limiting groove 35 to the surface of the boring arm 4;

[0048] Secondly, in order to ensure that the trapezoidal plate 16 drives the boring head 5 to move stably inside the head limiting groove 35, such as Figure 1 , Figure 2 and Figure 8 As shown, the cross section of the corner groove 18 is an isosceles right triangle. By making the thickness of the tool head limiting groove 35 greater than the thickness of the tool head receiving groove 6, the inclined surface of the trapezoidal plate 16 is adapted to the top inner wall of the corner groove 18. The boring tool head 5 is slidably connected inside the tool head limiting groove 35, while the second drive plate 15 is slidably connected to the outside of the trapezoidal plate 16 through the corner groove 18. With the help of the inclined inner wall of the corner groove 18 and the top inclined surface of the trapezoidal plate 16, when the second drive plate 15 moves toward the boring tool head 5, it can push the trapezoidal plate 16 to the bottom, thereby driving the boring tool head 5 to extend out from inside the tool head limiting groove 35.

[0049] Furthermore, to prevent the trapezoidal plate 16 from disengaging from the second drive plate 15, and to ensure that the boring head 5 remains in a fixed position within the head limiting groove 35 when the second drive plate 15 is not moving, such as... Figure 4 and Figure 8 As shown, the interior of the second drive plate 15 has a strip groove 19 parallel to the inclined surface of the trapezoidal plate 16. The bottom of the trapezoidal plate 16 is connected to a limit rod 17 by a pin at one corner away from the boring head 5. By connecting the interior of the strip groove 19 with the interior of the corner groove 18, and the limit rod 17 is slidably connected to the interior of the strip groove 19, the second drive plate 15 and the trapezoidal plate 16 can maintain interaction. When the second drive plate 15 is stationary, the boring head 5 cannot move inside the head limit groove 35.

[0050] The above design utilizes a hydraulic push rod 10 to control the movement of the first pressure plate 29 toward the boring arm 4. A tension spring 33 (using a high-efficiency spring, similar to those used in motorcycle shock absorbers) drives the second pressure plate 30 to first apply pressure to the long rod 26. The long rod 26, with the aid of the first and second limiting plates 21 and 22, pushes the U-shaped frame 23 to apply pressure to the connecting rod 14. When the second drive plate 15 applies pressure to the trapezoidal plate 16 through the corner groove 18, the inclined inner wall of the corner groove 18 applies pressure to the inclined surface of the trapezoidal plate 16, causing the trapezoidal plate 16 to drive the boring cutter head 5 within the cutter head receiving groove 6 and into the cutter head limiting groove 3. The internal movement of 5 (at this time, the limit rod 17 moves within the strip groove 19 to restrict the movement of the boring head 5 when the second drive plate 15 does not apply pressure to the trapezoidal plate 16, and when the second drive plate 15 is far away from the boring head 5, the limit rod 17 and the strip groove 19 can be used to make the boring head 5 return to the inside of the head limit groove 35), so that the boring edge on the boring head 5 extends out from the inside of the boring arm 4. When the boring equipment works and drives the drive shaft 1 to rotate at one end connected to the motor on the boring equipment, the boring head 5 can be driven by the drive shaft 1 and the boring arm 4 to process spaces of different diameters inside the gearbox to be processed.

[0051] Example 2:

[0052] Based on Example 1, this example describes the specific structure between the drive shaft 1 and the boring arm 4, such as... Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, the inner side of the bottom of the limiting trapezoidal block 7 is provided with a track bar 36 connected to the adapter seat 3, the bottom of the first drive plate 8 is provided with a track groove 31, and the guide rod 25 is externally connected with a spring 24. The inclination of the track groove 31 is the same as the inclination direction and inclination angle of the inclined surface on the trapezoidal plate 16.

[0053] The boring arm 4 has a seat plate 11 integrally formed at one end near the drive shaft 1. The top of the boring arm 4 near the drive shaft 1 is provided with a first movable slot 12, and the top of the support seat 2 is provided with a second movable slot 20. The seat plate 11 is assembled to the surface of the support seat 2 away from the track bar 36. The U-shaped frame 23 is movably connected to the inside of the second movable slot 20 and the first movable slot 12.

[0054] Hooks 34 are welded to the surfaces of the first pressure plate 29 and the second pressure plate 30 facing each other. The two ends of the tension spring 33 are respectively sleeved to the outside of the two hooks 34. A back plate 9 is welded to the inner wall of the receiving groove 32 away from the boring arm 4. The end of the hydraulic push rod 10 away from the first pressure plate 29 is assembled to the surface of the back plate 9.

[0055] The first drive plate 8 is slidably connected to the outside of the track bar 36 via the track groove 31. The spring 24 is supported between the first drive plate 8 and the second limiting plate 22 on the guide rod 25. When the first pressure plate 29 is pushed by the hydraulic push rod 10, the second pressure plate 30 is driven by the tension spring 33 to first apply pressure to the long rod 26. The long rod 26 pushes the U-shaped frame 23 to apply pressure to the connecting rod 14 with the help of the first limiting plate 21 and the second limiting plate 22. The second drive plate 15 applies pressure to the trapezoidal plate 16 through the corner groove 18. After the boring head 5 extends from the inside of the boring arm 4 to the limit position, the first pressure plate 29... 9 continues to slide outside the long rod 26, stretching the tension spring 33 to make the first pressure plate 29 press against the first drive plate 8, which can make the first drive plate 8 push the track bar 36 to drive the adapter 3 to move relative to the support 2 in the direction of the boring head 5, realizing the state of the boring arm 4 and the drive shaft 1 changing from coaxial to different axes, which makes it easier to realize that the boring head 5 is pushed by the bipolar control structure between the drive shaft 1 and the boring arm 4. First, it extends out from the inside of the boring arm 4 in a direction perpendicular to the axis of the boring arm 4, and then the bipolar control structure pushes the adapter 3 to move outside the limiting trapezoidal block 7 in the direction of the boring head 5.

[0056] In this state, if the drive shaft 1 and the boring arm 4 are coaxial, and the boring head 5 extends from the inside of the head limiting groove 35, the boring space radius r can be obtained. When the drive shaft 1 and the boring arm 4 are not coaxial, the boring space radius R can be obtained (radius R is greater than radius r, such as...). Figure 10 As shown in the figure, this is beneficial for increasing the length of the boring head 5 inside the gearbox and expanding the boring space;

[0057] Secondly, to prevent the first drive plate 8 from moving away from the top inner wall of the storage groove 32 inside the storage groove 32, such as Figure 6 and Figure 7 As shown, a storage groove 32 is provided at the bottom of the drive shaft 1 near the boring arm 4. Limiting ribs 27 are integrally formed on both sides of the inner wall of the storage groove 32. Limiting grooves 28 are provided on both sides of the first drive plate 8. The four limiting ribs 27 are adapted to be connected inside the limiting grooves 28, so that the first drive plate 8 can be slidably connected between the two limiting ribs 27 through the two limiting grooves 28. This facilitates the first drive plate 8 to move in a fixed direction and push the U-shaped frame 23 to move on the long rod 26. The first drive plate 8 is used to position the long rod 26.

[0058] The above design utilizes a hydraulic push rod 10 to push a first pressure plate 29, and a tension spring 33 to drive a second pressure plate 30 to apply pressure to a long rod 26. The long rod 26, with the help of a first limiting plate 21 and a second limiting plate 22, pushes a U-shaped frame 23 to apply pressure to a connecting rod 14. This causes the second drive plate 15 to apply pressure to a trapezoidal plate 16 through a corner groove 18. After the boring head 5 extends from the inside of the boring arm 4 to its limit position, the first pressure plate 29 continues to slide outside the long rod 26. The tension spring 33 is stretched so that the first pressure plate 29 applies pressure to the first drive plate 8. This allows the first drive plate 8 to push the track bar 36, causing the adapter 3 to move relative to the support 2 in the direction of the boring head 5. This achieves the change of the boring arm 4 and the drive shaft 1 from coaxial to non-coaxial, which is beneficial for increasing the boring length of the boring head 5 inside the gearbox and expanding the boring space.

[0059] It is worth noting that the control of the hydraulic push rod 10 needs to be based on a control component that is separate from the drive shaft 1, such as a power supply plug that can be separated from each other (electric push rods can also adopt this method). This is not the focus of this application and is relatively easy to implement, as long as it does not interfere with the rotation of the drive shaft 1.

[0060] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
