Description

Technical Field

[0001] The present invention belongs to the technical field of two-way processing tooling for shaft parts, and particularly relates to a two-way processing tooling for shaft parts. Background Technique

[0002] Shaft parts are one of the typical parts often encountered in hardware fittings. It is mainly used to support transmission components, transmit torque and bear loads. According to the different structural forms of shaft parts, it can generally be divided into three categories: smooth shafts, stepped shafts and special-shaped shafts, or divided into solid shafts and hollow shafts.

[0003] At present, there are many deficiencies in the existing shaft grinding tooling in practical applications. On the one hand, the grinding discs of traditional grinding tooling usually adopt fixed installation or single-direction movement methods, which makes the contact area between the grinding disc and the shaft part relatively fixed. During long-term grinding, local areas of the grinding disc are excessively worn, resulting in uneven use of the grinding disc, shortening the service life of the grinding disc, and at the same time, it is difficult to ensure the consistency and uniformity of the surface grinding of the shaft part, affecting the processing quality of the shaft part. On the other hand, the existing shaft clamping devices have poor adaptability and are difficult to stably and effectively clamp shaft parts of different thickness specifications. When processing shaft parts of different sizes, it is necessary to frequently replace or adjust the clamping components, reducing production efficiency and increasing production costs. In addition, most shaft grinding tooling can only grind one end of the shaft part. If both ends of the shaft part need to be ground, the shaft part needs to be reinstalled and positioned, which is not only cumbersome to operate, but also the secondary clamping is likely to introduce clamping errors, further affecting the processing accuracy and quality of the shaft part. Especially when clamping non-circular shaft parts, due to the inability to automatically adjust the eccentricity of the shaft part, the clamping is unstable. In view of this, we propose a two-way processing tooling for shaft parts. Summary of the Invention

[0027] 3. The two-way processing tooling for the shaft part, through the cooperation of the turntable and control component set, can grind both ends of the shaft part, avoiding the cumbersome operation of re-clamping and positioning the shaft part in the traditional tooling. It not only saves a large amount of clamping time, improves the processing efficiency, but also eliminates the risk of clamping error introduced by secondary clamping, ensuring that the machining accuracy of both ends of the shaft part is highly consistent.

[0047] Among them, when the first servo motor 3 is powered on and started, the output shaft of the first servo motor 3 will rotate forward and drive the gear 12 to rotate. Under the action of meshing, the gear 12 will drive the toothed ring 11 to rotate, and the toothed ring 11 will drive the turntable 8 to rotate.

[0048] Embodiment 7: This embodiment provides a two-way processing tooling for shaft parts. In addition to including the technical solutions of the above embodiments, it also has the following technical features. On the side of the second clamping plate 15 opposite to the two first clamping plates 4, a number of rubber blocks 21 are fixedly installed, and the second clamping plate 15 is located between the two first clamping plates 4.

[0049] Among them, it is ensured that under the action of a number of rubber blocks 21, the shaft part can be clamped stably.

[0050] When the driving component drives the second clamping plate 15 and the two first clamping plates 4 to clamp the shaft part, the rubber blocks 21 provide flexible contact with the shaft part. Moreover, the driving component and the relevant mechanisms for clamping the shaft part can be combined to produce technical effects of dynamic pressure balance and thermal expansion compensation. During the process of clamping the shaft part, if the shaft part has a slight eccentricity, since the inclined limiting grooves 19 are symmetrically distributed in an inclined manner, when the sliding plate 14 is pushed by the first electric push rod 13, the movement of the round rod 20 in the limiting groove is decomposed into a horizontal component force and a vertical component force. The horizontal component force is the force that drives the moving block 6 to slide along the through groove 16, realizing the opening and closing actions of the first clamping plate 4 and the second clamping plate 15; the vertical component force is the additional pressure on the moving block 6 generated by the inclination angle of the limiting groove 19, and its magnitude changes dynamically with the displacement. Therefore, when there is eccentricity during the clamping process of the shaft part, the displacement amounts of the two round rods 20 in the limiting grooves 19 will be automatically adjusted due to uneven force. Specifically, when the eccentric side of the shaft part is the side with a larger gap, the round rod 20 slides deeper into the limiting groove 19, and the vertical component force increases, pushing the corresponding clamping plate to apply a greater clamping force; on the other side, which is the side with a smaller eccentric gap, the displacement amount of the round rod 20 decreases, and the vertical component force decreases accordingly, avoiding over-clamping and realizing automatic balance of the clamping force.

[0051] Secondly, the rubber blocks 21 not only maintain the stability of clamping, but also can automatically offset the clamping force fluctuation caused by the thermal expansion of the shaft part due to the gradual decrease of the elastic modulus of the rubber blocks 21 when the temperature of the shaft part rises during processing, and combine with the driving component to maintain the dynamic balance of clamping.

[0053] Among them, it is ensured that the output shaft of the second electric push rod 22 can drive the sliding rod 24 to displace.

[0054] Embodiment 9: This embodiment provides a two-way processing tooling for shaft parts. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The insertion block 32 is fixed to the rotating block 30 by two bolts.

[0055] Among them, it is ensured that the insertion block 32 can be fixed to the rotating block 30 by bolts.

A guide rod 31 is fixedly installed inside the sliding rod 24, and the telescopic rod 23 is slidably connected to the guide rod 31.

[0057] Among them, it is ensured that the telescopic rod 23 can slide on the guide rod 31, thereby ensuring that the displacement of the telescopic rod 23 is more stable.

[0058] In addition, in this embodiment, the power component and the driving component are combined to cooperate on the relevant parts clamped by the shaft part, not only achieving the effect of two-way grinding, but also generating a micro-vibration frequency difference with the power component through the damping characteristics of the rubber block 21 to avoid overall resonance, thereby achieving the effect of suppressing resonance. Secondly, through the coupling of the grinding pressure and displacement, when the grinding pressure exceeds the limit, the first electric push rod 13 automatically fine-tunes the clamping force to prevent deformation of the shaft part.

[0059] Working principle: When in use, the staff places the shaft part between the second clamping plate 15 and the two first clamping plates 4. Subsequently, the staff can power on and start the first electric push rod 13. The output shaft of the first electric push rod 13 will contract and drive the sliding plate 14 to displace towards the direction close to the first electric push rod 13. At this time, the two round rods 20 will slide in the two limiting grooves 19 respectively and be squeezed to approach each other. The two round rods 20 will respectively drive the two moving blocks 6 to approach each other in the through groove 16. At this time, the second clamping plate 15 and the two first clamping plates 4 will approach each other until a number of rubber blocks 21 on the opposite sides of the second clamping plate 15 and the two first clamping plates 4 contact the shaft part. This enables the second clamping plate 15 and the two first clamping plates 4 to clamp the shaft part. Under the action of a number of rubber blocks 21, it is ensured that the shaft part can be clamped stably and there will be no shaking situation; Subsequently, the staff can energize and start the second electric push rod 22. The output shaft of the second electric push rod 22 will drive the sliding rod 24 to displace towards the direction close to the second electric push rod 22 until the grinding disc 27 contacts one end of the shaft part. At this time, the staff can energize and start the third servo motor 10 and the second servo motor 5. The output shaft of the second servo motor 5 will drive the rotating block 30 to rotate. The rotating block 30 will drive the inserting block 32 to rotate. The inserting block 32 will drive the grinding disc 27 to rotate. At the same time, the output shaft of the third servo motor 10 will drive the rotating disc 25 to rotate. The rotating disc 25 will drive the cylinder 26 to rotate. The cylinder 26 will drive the connecting plate 7 to displace up and down repeatedly. And the cylinder 26 will slide in the through hole 33. The connecting plate 7 will drive the telescopic rod 23 to displace up and down repeatedly on the guide rod 31 in the sliding rod 24. The connecting plate 7 will drive the inserting block 32 and the grinding disc 27 to displace above repeatedly through the rotating block 30, so as to ensure that the grinding disc 27 can be used evenly; When it is necessary to grind the other end of the shaft part, the staff can energize and start the first servo motor 3. The output shaft of the first servo motor 3 will rotate forward and drive the gear 12 to rotate. Under the action of meshing, the gear 12 will drive the toothed ring 11 to rotate. The toothed ring 11 will drive the turntable 8 to rotate. The turntable 8 will drive the sliding rod 24 to rotate. The sliding rod 24 will drive the telescopic rod 23 to rotate. The telescopic rod 23 will drive the connecting plate 7 to rotate. The connecting plate 7 will drive the inserting block 32 and the grinding disc 27 to rotate 180° through the rotating block 30. When it is necessary to restore the grinding disc 27 to its original position, the output shaft of the first servo motor 3 can be rotated reversely.
