A multi-dimensional adjustable gear hole turning machine

Abstract

This invention discloses a multi-dimensional adjustable gear turning machine, including a spindle box, a spindle body, and a clamping component. The spindle body is connected to the outside of the spindle box and drives the spindle body to rotate. The clamping component is installed at the outer end of the spindle body and includes: a first mating cover connected to the output end of the spindle body; a second mating cover that mates with the first mating cover, and the first and second mating covers generate a squeezing force when clamping the gear; and an inclined portion disposed between the first and second mating covers. By rotating the adjusting threaded rod, the second clamping plate naturally tilts. By rotating the fastening bolt, the first and second clamping plates clamp the gear, fixing it in an inclined position for turning a slanted hole, thus completing the machining of the slanted hole. After the second clamping plate tilts, it is subjected to a squeezing and clamping action. The hinge position is where the round shaft fits against the inner wall of the arc-shaped notch, allowing the force to be directly transmitted to the second mating cover, avoiding deformation at the hinge position and ensuring clamping accuracy.

Description

Technical Field

[0001] The invention relates to the technical field of gear turning, in particular to a multi-dimensional adjustable gear hole turning machine. Background Art

[0002] In gear processing, holes are opened on large gears mainly to reduce the overall weight of the gears, lower the mass center of the gears, and thus reduce the moment of inertia.

[0003] By turning, the size and shape of the hole can be precisely controlled. Turning can produce a smooth hole surface and reduce surface roughness, thereby improving the quality of the hole. This helps to reduce stress concentration and wear problems caused by uneven hole surfaces. In addition, turning has high flexibility and can produce holes of various complex shapes and sizes, and the holes may need to be designed as tapered holes.

[0004] On certain gears, it is necessary to have an inclined hole, which is used as an oil injection hole to inject lubricating oil into the gear to improve the transmission efficiency and life of the gear. This type of inclined hole is usually at a certain angle to the horizontal direction to facilitate the distribution and flow of the lubricating oil.

[0005] In the process of machining the inclined hole, the gear needs to be clamped. When machining the inclined hole, the inclined hole is generally in a vertical or horizontal position, and the gear clamping is tilted, which makes it difficult to machine the inclined hole.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 the present invention.

[0036] See also Figure 1-Figure 8 The present invention provides a technical solution: a multi-dimensional adjustable gear boring machine, comprising a spindle box 1, a spindle body 2 and a clamping component 3, wherein the spindle body 2 is connected to the outside of the spindle box 1 and drives the spindle body 2 to rotate, wherein the spindle box 1 transmits the power of the motor to the spindle body 2 through the transmission system to rotate the spindle body 2, and the clamping component 3 is installed at the outer end of the spindle body 2, and the clamping component 3 comprises a matching cover 1 31, a matching cover 2 32 and an inclined portion 4;

[0037] The matching cover 1 31 is connected to the output end of the main shaft body 2;

[0038] The second matching cover 32 matches with the first matching cover 31, and when the first matching cover 31 and the second matching cover 32 clamp the gear, an extrusion force is generated, and the first matching cover 31 and the second matching cover 32 are in a buckled state, so as to limit the position of the gear;

[0039] The inclined portion 4 is disposed between the first matching cover 31 and the second matching cover 32 for clamping the gear, and the inclined portion 4 can be adjusted in an inclined manner.

[0040] like Figure 2 and Figure 3 As shown, a polygonal opening 21 is formed at the outer end of the main shaft body 2, and a polygonal shaft 311 is integrally formed at the outer end of the matching cover 31. The polygonal shaft 311 matches with the polygonal opening 21. A fixing bolt 312 is provided inside the matching cover 31. The fixing bolt 312 passes through the polygonal shaft 311 and is threadedly connected with the main shaft body 2, so that the main shaft body 2 drives the matching cover 31 to rotate, and avoids separation under the action of the fixing bolt 312.

[0041] like Figure 3 As shown, the outer side of the matching cover 31 is also provided with an arc-shaped opening 313 connected to the interior, and the outer arc surface of the matching cover 31 is also integrally provided with an extension block 314;

[0042] An operation opening 321 for turning is provided through the middle of the second matching cover 32, an arcuate edge 322 is integrally provided on one side of the second matching cover 32, and the arcuate edge 322 cooperates with the arcuate opening 313. An extension block 323 is also integrally provided on the outer side of the second matching cover 32, and a fastening bolt 324 is inserted into the extension block 323, and the fastening bolt 324 is threadedly connected to the extension block 1 314, and is used to control the distance between the first matching cover 31 and the second matching cover 32. The fastening bolt 324 is rotated to adjust the distance between the first matching cover 31 and the second matching cover 32. When the gear is installed, the gear is squeezed and clamped by rotating the fastening bolt 324 to achieve the function of fixing the gear.

[0043] It should also be noted that the arcuate edge 322 cooperates with the arcuate opening 313 to limit the position between the mating cover 2 32 and the mating cover 1 31, and the mating cover 2 32 rotates with the mating cover 1 31 to avoid offset, and the shear force generated during the rotation acts on the arcuate edge 322 to prevent the fastening bolts 324 from being affected and loosening. Under the self-locking action of the fastening bolts 324, the gears are clamped tightly to prevent loosening.

[0044] like Figure 4 and Figure 6 As shown, the inclined portion 4 includes a clamp plate 1 41 and a clamp plate 2 42 for clamping the gear. The clamp plate 1 41 and the clamp plate 2 42 are both installed between the matching cover 1 31 and the matching cover 2 32. The clamp plate 1 41 and the clamp plate 2 42 can be tilted. It should be noted that the clamp plate 1 41 and the clamp plate 2 42 are located between the matching cover 1 31 and the matching cover 2 32, and are subjected to the extrusion effect generated by the matching of the matching cover 1 31 and the matching cover 2 32 to clamp the gear.

[0045] like Figure 4 and Figure 6 As shown, a mounting opening 411 is provided on the inner side of the matching cover 1 31, a mounting block 412 is clamped in the mounting opening 411, a clamping plate 41 is hinged on the outer side of the mounting block 412, and the clamping plate 41 can be tilted along the mounting block 412;

[0046] One side of the second splint 42 is hinged to the inner side of the second matching cover 32, and a circular opening 421 for turning operation is penetrated in the middle position of the second splint 42, and an adjusting threaded opening 425 is penetrated on the second matching cover 32. The adjusting threaded opening 425 is threadedly connected with an adjusting threaded rod 426, and the adjusting threaded rod 426 is abutted against the second splint 42. The adjusting threaded rod 426 is used to control the inclination of the second splint 42, and the end of the adjusting threaded rod 426 is semicircular. It should be noted that the adjusting threaded rod 426 squeezes the second splint 42, and its semicircular end can avoid scratches on the second splint 42. In addition, when the adjusting threaded rod 426 is rotated, the second splint 42 is tilted, and the angle of inclination can be measured. The inclination angle of the second splint 42 is the inclination angle of the gear. The adjusting threaded rod 426 can also fine-tune the inclination angle of the second splint 42.

[0047] like Figure 5 and Figure 7 As shown, a ball 413 is fixed to the outer side of the mounting block 412, and a sleeve 415 is integrally formed on the inner side of the splint 41. The ball 413 and the sleeve 415 are sleeved together, and the two are arranged in a ball joint. It should be noted that under the extrusion force on the splint 41, the force can be directly applied to the ball 413 and the sleeve 415 to achieve a supporting effect.

[0048] The mounting block 412 is polygonal in design, which can achieve good power transmission and enable the mounting block 412 to rotate with the mounting block to avoid slipping. An arc-shaped protruding layer 414 is integrally provided on the outer side of the sphere 413, and an arc-shaped recessed layer 416 is provided on the inner side of the sleeve 415. The protruding layer 414 cooperates with the recessed layer 416 to limit the tilting direction of the splint 41 so that the splint 41 can only move along the arc direction of the protruding layer 414, so that the movement direction of the splint 41 is limited to avoid unnecessary deviation. It should also be noted that the protruding layer 414 cooperates with the recessed layer 416 to also have a transmission effect, so that the splint 41 rotates with the mounting block 412 to ensure the rotation of the gear.

[0049] A circular shaft body 422 is integrally formed on one side of the second clamping plate 42, and a metal plug rod 423 passes through the circular shaft body 422. The metal plug rod 423 is fixed to the second matching cover 32, and an arc-shaped arc-shaped recess 424 is provided on the inner side of the matching cover 32. The circular shaft body 422 is embedded in the arc-shaped recess 424, and the circular shaft body 422 fits the arc-shaped recess 424. It should be noted that the axes of the circular shaft body 422, the metal plug rod 423 and the arc-shaped recess 424 are all overlapped, so that the rotation can be smoother and avoid obstruction. In addition, when clamping The second clamping plate 42 can be directly transferred to the second mating cover 32 to avoid deformation of the first clamping plate 41 and the second clamping plate 42. Figure 8 As shown, the clamping plate 1 41 and the clamping plate 2 42 are located between the matching cover 1 31 and the matching cover 2 32. When the matching cover 1 31 and the matching cover 2 32 are close to each other for matching, the clamping plate 1 41 and the clamping plate 2 42 can squeeze the gear.

[0050] The working principle of the present invention is as follows: the spindle box 1 is used to control the rotation of the spindle body 2, and the matching cover 1 31 is matched with the spindle body 2 to realize that the matching cover 1 31 also rotates. In the process of clamping the gear, the matching cover 2 32 needs to be removed, and then the gear is attached to the clamping plate 1 41 or the clamping plate 2 42, and then the matching cover 1 31 and the matching cover 2 32 are matched, and according to the angle at which the inclined hole needs to be tilted, the adjusting threaded rod 426 is rotated to make the adjusting threaded rod 426 squeeze the clamping plate 2 42, and the clamping plate 2 42 naturally becomes inclined, and then the fastening bolt 324 is rotated to make the matching cover 1 31 and the matching cover 2 32 match and relatively squeeze, and the clamping plate 1 41 and the clamping plate 2 42 clamp the gear, and the clamping plate 1 41 also becomes inclined, and the gear is fixed in an inclined state by the effect of squeezing, and then when turning the inclined hole, the drill bit installed on the tailstock is first used to open the inclined hole on the gear, and then the inclined hole is enlarged by turning to complete the processing of the inclined hole.

[0051] Among them, when the clamp plate 1 41 and the clamp plate 2 42 clamp the gear, the semicircular end of the adjusting threaded rod 426 is squeezed against the clamp plate 2 42, and the clamp plate 2 42 is tilted along the hinged position. It should be noted that after the clamp plate 2 42 is tilted, it is squeezed and clamped, and the clamping effect is at the hinged position of the clamp plate 2 42 and the position against the adjusting threaded rod 426. The hinged position is where the round shaft body 422 fits against the inner wall of the arc-shaped recess 424, so that the force is directly transmitted to the matching cover 2 32, avoiding deformation at the hinged position, and also avoiding deformation when the clamping force is relatively large, thereby ensuring the clamping accuracy.

[0052] Under the action of the metal plug 423 and the circular shaft 422, the tilting direction of the second clamp 42 is restricted. In addition, through the cooperation of the protruding layer 414 and the recessed layer 416, the tilting direction of the first clamp 41 is also restricted. After the gear is clamped, the position is fixed, and the tilting state remains unchanged during the rotation process, ensuring that the inclined hole on the gear has high precision. When the inclined gear rotates, the inclined hole is in a horizontal state, and the inclined hole machined has high precision.

[0053] The inclined hole is often the eccentric position of the gear. Therefore, when the gear is clamped between the clamping plate 1 41 and the clamping plate 2 42, the gear can be moved between the clamping plate 1 41 and the clamping plate 2 42 to change the position of the gear and change the position of the gear clamping. The position of the inclined hole coincides with the axis of the clamping component 3, thereby realizing the processing of the eccentric inclined hole and the clamping of gears of different sizes and thicknesses.
