Description
Technical Field
[0001] The utility model relates to the technical field of spline shaft processing, in particular to a spline shaft finishing device. Background Art
[0002] Spline shafts can be used for mechanical transmission. Like flat keys, semicircular keys, and oblique keys, they all transmit mechanical torque. There are longitudinal keyways on the surface of the shaft, and the rotating parts on the shaft also have corresponding keyways, which can keep rotating synchronously with the shaft. While rotating, some can also slide longitudinally on the shaft, such as gearbox shift gears.
[0003] There are many factors that affect the quality of spline shafts, such as the following common factors: 1. The spline shaft in the prior art is an integrated part. The spline shaft is processed by milling, extrusion and other methods, which will cause burrs on the shaft body. The burrs on the surface of the shaft body will affect the assembly effect; 2. In the actual processing process, one end of the shaft body needs to be clamped by a clamp. If the shaft body is too long, it is easy to deviate from the processing axis, affecting the processing accuracy; 3. The milling cutter cannot move accurately according to shafts of different sizes.

[0019] The utility model is specifically introduced below in conjunction with the accompanying drawings and embodiments.
[0020] Reference Figures 1 to 4The present embodiment is a spline shaft finishing equipment, including a base 1, a milling mechanism 2, a grinding mechanism 3, and a deviation correction mechanism 4. Two parallel slide rails 1a are arranged in the middle of the top of the base 1, and a first vertical plate 1b is slidably clamped on the slide rail 1a. A second vertical plate 1c and a first telescopic cylinder 1d are arranged on both sides of the middle of the top of the base 1. The end of the telescopic rod of the first telescopic cylinder 1d is connected to the bottom of the first vertical plate 1b. The first vertical plate 1b and the second vertical plate 1c are respectively provided with a dividing chuck 1e and a pin device 1f on the opposite end surfaces. The top of the base 1 Support seats 1g are respectively provided at the two ends of the front side, and a first threaded rod 1h is rotatably provided between the two support seats 1g. A rotating motor 1i is provided on the side of one of the support seats 1g, and the output end of the rotating motor 1i passes through the support seat 1g and is transmission-connected with the first threaded rod 1h. A moving seat 1j is provided between the two support seats 1g, and one end of the moving seat 1j is threadedly connected with the first threaded rod 1h. The middle part of the moving seat 1j is slidably engaged with the slide rail 1a, and a milling mechanism 2, a grinding mechanism 3, and a correction mechanism 4 are provided at the top of the moving seat 1j.
[0021] One end of the spline shaft to be processed is clamped by the dividing chuck 1e, and the first telescopic cylinder 1d is controlled so that the telescopic rod of the first telescopic cylinder 1d pushes the first vertical plate 1b to slide close to the second vertical plate 1c until the ejector device 1f on the second vertical plate 1c pushes against the other end of the spline shaft. The rotating motor 1i is turned on, and the rotating motor 1i drives the first threaded rod 1h to rotate, thereby driving the moving seat 1j to move. The correction mechanism 4 on the moving seat 1j can prevent the spline shaft from deviating from the processing axis during processing. The spline shaft is then milled by the milling mechanism 2, and then polished by the polishing mechanism 3 after completion.
[0022] In this embodiment, the correction mechanism 4 includes a third vertical plate 4a arranged on one side of the movable seat 1j, a through hole 4b is provided on the upper portion of the third vertical plate 4a, three second telescopic cylinders 4c are circumferentially arranged on the outer periphery of the through hole 4b, ball seats 4d are provided at the ends of the telescopic rods of the three second telescopic cylinders 4c, a rolling ball 4e is rollingly clamped in the ball seat 4d, and the dividing chuck 1e, the ejector device 1f and the through hole 4b are coaxially arranged.
[0023] Pass the spline shaft to be processed through the through hole 4b in the third vertical plate 4a, and control the three second telescopic cylinders 4c to make the telescopic rod extend toward the surface of the spline shaft until the ball 4e in the ball seat 4d abuts against the surface of the spline shaft. When the movable seat 1j moves, the ball 4e rolls along the axial direction of the spline shaft. When the spline shaft rotates, the ball 4e can also rotate, so the three balls 4e around the outer circumference of the spline shaft can play a supporting role without affecting the state of the spline shaft.
[0024] In this embodiment, a support plate 5 is provided in the middle of the top of the moving seat 1j, and a first guide rail 5a and a second guide rail 5b are provided side by side at the top of the moving seat 1j located on the side of the support plate 5.
[0025] In this embodiment, the milling mechanism 2 includes a fourth vertical plate 2a that is slidably clamped on the first guide rail 5a, and a first bearing 5c is arranged at a position of the support plate 5 corresponding to the fourth vertical plate 2a. A second threaded rod 5d is fixed in the inner ring of the first bearing 5c, and one end of the second threaded rod 5d is threadedly connected to the fourth vertical plate 2a. A first hand wheel 5e is arranged at the other end of the second threaded rod 5d, and a handle is arranged on the first hand wheel 5e.
[0026] Since the fourth vertical plate 2a is slidably connected to the first guide rail 5a, the operator holds the handle and shakes the first hand wheel 5e, driving the second threaded rod 5d to rotate and further driving the fourth vertical plate 2a to approach the through hole 4b or move away from the through hole 4b.
[0027] In this embodiment, the milling mechanism 2 also includes a top plate 2b arranged at the top of the fourth vertical plate 2a, a servo motor 2c is arranged below the top plate 2b, a milling cutter head 2d is arranged at the end of the rotating shaft of the servo motor 2c, a third threaded rod 2e is threadedly connected to the top plate 2b, one end of the third threaded rod 2e is rotatably connected to the top of the servo motor 2c through a second bearing 2f, the other end of the third threaded rod 2e is connected to a second hand wheel 2g, and a handle is arranged on the second hand wheel 2g.
[0028] Turn on the servo motor 2c, and the servo motor 2c drives the milling cutter head 2d to rotate and then perform milling operations on the spline shaft. By rotating the second hand wheel 2g to drive the third threaded rod 2e to rotate and then adjust the vertical position of the servo motor 2c, the spline shaft can be milled accurately.
[0029] In this embodiment, a vertical downward slot 2a-1 is provided at a position of the fourth vertical plate 2a corresponding to the servo motor 2c, and a clamping rod 2c-1 is provided on the side of the servo motor 2c, and one end of the clamping rod 2c-1 is slidably clamped in the slot 2a-1.
[0030] The servo motor 2c is slidably engaged in the engaging groove 2a-1 through the engaging rod 2c-1, so as to prevent the servo motor 2c from being deviated in the horizontal direction and affecting the milling accuracy.
[0031] In this embodiment, the grinding mechanism 3 includes two pressure plates 3a slidably clamped on the second guide rail 5b, and the two pressure plates 3a are symmetrically arranged about the axis of the through hole 4b. A third bearing 5f is arranged at a position of the support plate 5 corresponding to the two pressure plates 3a. A bidirectional screw rod 5g is fixed in the inner ring of the third bearing 5f. The bidirectional screw rod 5g is threadedly connected to the two pressure plates 3a in turn, and a third hand wheel 5h is arranged at the end of the bidirectional screw rod 5g, and a handle is arranged on the third hand wheel 5h.
[0032] The bidirectional screw 5g is driven to rotate by rotating the third hand wheel 5h, thereby driving the two pressure plates 3a to approach each other. Since the two pressure plates 3a are symmetrically arranged with respect to the axis of the through hole 4b, the two pressure plates 3a can clamp the spline shaft at the same time when they approach each other.
[0033] In this embodiment, a grinding assembly is arranged at the same height between the two pressing plates 3a and the through hole 4b, and the grinding assembly includes a grinding block 3c, and the upper and lower ends of the grinding block 3c are respectively hinged with a grinding plate 3d, and the angle between the grinding plate 3d and the grinding block 3c is an obtuse angle, and the side of the grinding plate 3d is connected to the side wall of the pressing plate 3a through a rubber rod 3e.
[0034] When the two pressure plates 3a approach each other, the two grinding blocks 3c rest against the two sides of the spline shaft. At the same time, the grinding plates 3d at the upper and lower ends of the grinding blocks 3c will also cling to the surface of the spline shaft under the elastic force of the rubber rod 3e. When the moving seat 1j moves axially along the spline shaft, the grinding blocks 3c and the grinding plates 3d can grind the surface of the spline shaft.
[0035] Working principle: Clamp one end of the spline shaft to be processed by the indexing chuck 1e, control the first telescopic cylinder 1d, so that the telescopic rod of the first telescopic cylinder 1d pushes the first vertical plate 1b to slide close to the second vertical plate 1c, and at the same time, the spline shaft to be processed passes through the through hole 4b in the third vertical plate 4a, until the ejector device 1f on the second vertical plate 1c pushes against the other end of the spline shaft, and control the three second telescopic cylinders 4c to make the telescopic rod extend toward the center of the spline shaft until the ball 4e in the ball seat 4d is The three balls 4e around the outer circumference of the spline shaft abut against the surface of the spline shaft and can play a supporting role without affecting the state of the spline shaft, thereby preventing the spline shaft from deviating from the processing axis under the action of gravity or external force. The servo motor 2c is then turned on, and the servo motor 2c drives the milling cutter head 2d to rotate to perform milling operations on the spline shaft. The third threaded rod 2e is driven to rotate by turning the second hand wheel 2g, thereby adjusting the vertical position of the servo motor 2c. The operator then holds the handle and shakes the first hand wheel 5e, which drives the second threaded rod 5d to rotate and thereby drives the fourth vertical plate 2a to approach the spline shaft, so that the spline shaft can be milled accurately. The rotating motor 1i is then turned on, and the rotating motor 1i drives the first threaded rod 1h to rotate, thereby driving the moving seat 1j to move, and the milling mechanism 2 on the moving seat 1j performs milling operations along the axial direction of the spline shaft. After all the milling operations are completed, the first hand wheel 5e is shaken, which drives the second threaded rod 5d to rotate and thereby drives the fourth vertical plate 2a away from the spline shaft, and then the third hand wheel is shaken. 5h drives the bidirectional screw rod 5g to rotate, and then drives the two pressure plates 3a to approach each other. When the two pressure plates 3a approach each other, the two grinding blocks 3c abut against the two sides of the spline shaft. At the same time, the grinding plates 3d at the upper and lower ends of the grinding block 3c will also cling to the surface of the spline shaft under the elastic force of the rubber rod 3e. When the moving seat 1j moves axially along the spline shaft, the grinding block 3c and the grinding plate 3d can grind the surface of the spline shaft, and the burrs on the surface of the spline shaft can be cleaned by cooperating with the dividing chuck 1e.
[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
