Description

Technical Field

[0001] The invention relates to the technical field of forging grinding, in particular to automatic forging grinding equipment. Background Art

[0002] Semi-axle (such as Figure 8 The axle (as shown) is also called the drive shaft, which is the shaft connecting the differential and the drive wheel. The half-shaft is the shaft that transmits torque between the gearbox reducer and the drive wheel. During the forging process of the half-shaft, burrs, scales, cracks, folds and other defects will appear on its surface. Therefore, before using the half-shaft, it is necessary to grind the surface of the half-shaft to improve the surface finish of the half-shaft and remove its surface defects, thereby reducing the contact friction and wear between the half-shaft and the bearings and other components, and improving the transmission efficiency of the half-shaft.

[0003] At present, when grinding a half shaft, it is necessary to first fix the two ends of the half shaft in a fixture, then start the grinding roller and rotate the half shaft fixed in the fixture, and then move the half shaft horizontally so that the grinding roller can fully grind the surface of the half shaft, so as to complete the grinding of the half shaft. The above grinding method has the following disadvantages: 1. During the above operation, the grinding roller does not provide stable support for the other side of the half shaft while grinding the surface of one side of the half shaft, so that the half shaft is prone to shaking or offset during the grinding process, resulting in the grinding roller being unable to evenly contact the surface of the half shaft, which in turn causes the surface of the half shaft to be rough after grinding. 1. The grinding roller is not consistent, which affects the dimensional accuracy and surface quality of the half shaft; 2. When grinding the half shaft, only the two ends of the half shaft are fixed. Therefore, when the grinding roller grinds to the end that deviates from the center of the half shaft, the pressure applied by the grinding roller will be concentrated on the end that deviates from the center, and the other side has no support, which causes uneven force on the half shaft, making the half shaft prone to bending or local deformation, affecting its geometric accuracy and straightness. In addition, the pressure of the grinding roller is concentrated on the end that deviates from the center, which will cause excessive stress in the local area and form a stress concentration area on the surface of the half shaft, thereby reducing its fatigue strength and shortening its service life.

The automatic forging grinding equipment, through the coordinated use of the positioning mechanism, the bearing mechanism and the grinding mechanism, adopts an integrated operation model of positioning, bearing and grinding to complete the automatic grinding operation on the surface of the half-shaft. When the half-shaft is ground, the grinding roller and the extrusion roller implement stable three-point support for the grinding part of the half-shaft shaft rod, and implement adaptive circumferential extrusion of the shaft rod following the change of the grinding position.

[0038] See also Figure 1 , Figure 3 , Figure 4 , Figure 5and Figure 7 The support portion 42 includes a support arm 421 fixedly mounted on the left end of the first slider 413, an electric slide rail 422 is fixedly mounted on the lower end surface of the upper support arm 421, and a side wall of the other support arms 421 close to the upper support arm 421 is fixedly mounted with a limiting slide rail 423, a support slide 424 is fixedly mounted on the movable end of the electric slide rail 422, and a support slide 424 is also slidably mounted in the limiting slide rail 423, a positioning rod is fixedly mounted on the left end surface of the support arm 421, and the spring telescopic rod 7 is composed of a sliding sleeve, a sliding rod slidably mounted in the sliding sleeve, and a tension spring between the sliding rod and the sliding sleeve, a jack is commonly provided on the sliding rod and the sliding sleeve, and a spring telescopic rod 7 is commonly hinged between adjacent support slides 424.

[0039] See also Figure 3 and Figure 4 The clamping portion 43 includes a three-jaw chuck 431 fixedly mounted at the center of the left end surface of the first alignment disk 411, and a pressure roller 432 is rotatably mounted on the clamping end of the three-jaw chuck 431 through a support frame.

[0040] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 The mating part 51 includes a second alignment disk 511 fixedly mounted on the right end face of the second slide seat 3 and coaxial with the first alignment disk 411. A second slideway 512 corresponding to the first slideway 412 is provided on the right end face of the second alignment disk 511. A second slider 513 is slidably mounted in the second slideway 512. A slot for mating with the corresponding alignment rod is provided on the right end face of the second slider 513. A spring is fixedly mounted between the second slider 513 and the second slideway 512.

[0041] See also Figure 1 and Figure 6 The rotating part 52 includes a limiting plate 521 installed at the center of the right end surface of the second alignment plate 511 through a bearing, and the right end surface of the limiting plate 521 is provided with a limiting protrusion for limiting the semi-shaft disc part. A connecting rod 522 that passes through the right end surface of the second alignment plate 511 is installed in the second slide 3 through a bearing, and the right end of the connecting rod 522 is fixedly connected to the limiting plate 521, and a second motor 523 whose output end is fixedly connected to the connecting rod 522 is fixedly installed on the second slide 3.

[0042] During the specific work, when the half-shaft needs to be polished, first place the disc part on the half-shaft to be polished on the limiting plate 521, and at the same time pass the limiting protrusion through the through hole of the disc part, so that the disc part of the half-shaft fits with the right end face of the limiting plate 521, thereby completing the placement of the half-shaft.

[0043] Then, the second slide 3 is brought closer to the first slide 2 with the half-shaft until the other end of the half-shaft contacts the left end face of the three-jaw chuck 431. At this time, the bolts on the second slide 3 and the first slide 2 can be manually rotated with an electric rotating tool to fix the second slide 3 and the first slide 2 on the slide rail to prevent the two from sliding. Then, the three-jaw chuck 431 is used to make its clamping end bring the pressure roller 432 closer to the half-shaft synchronously until the pressure roller 432 squeezes and clamps the half-shaft. The pressure roller 432 in contact with the half-shaft will not hinder the rotation of the half-shaft, thereby completing the fixation of the half-shaft.

[0044] In the process of the second slide 3 approaching the first slide 2, the alignment rod on the support arm 421 will be inserted into the slot of the second slider 513, and then the first motor 415 will be started to rotate the plurality of lead screws 414 synchronously through the second bevel gear and the first bevel gear, so that the three support arms 421 with the grinding mechanism 6 will approach the half-shaft synchronously through the first slider 413, and when the support arm 421 with the grinding part 61 contacts the half-shaft, the first motor 415 can be stopped.

[0045] See also Figure 2 , Figure 5 and Figure 7 The grinding part 61 includes a grinding roller 611 rotatably mounted on the support slide 424 of the electric slide rail 422 through a set shaft, and a squeezing roller 612 is rotatably mounted on the support slide 424 of the limiting slide rail 423 through a set shaft.

[0046] See also Figure 2 , Figure 5 and Figure 7 The locking portion 64 includes an inserting rod 641 inserted into the inserting hole of the spring telescopic rod 7.

[0047] During specific operation, as the three support arms 421 carry the grinding mechanism 6 toward the half-shaft synchronously, the grinding roller 611 and the squeezing roller 612 will be synchronously contacted with the outer ring wall of the half-shaft through the support slide 424, so that the grinding roller 611 and the squeezing roller 612 implement three-point support on the half-shaft.

[0048] During this process, the adjacent supporting slides 424 will compress the corresponding spring telescopic rods 7, and when the grinding roller 611 and the squeezing roller 612 contact the half-axis, the sliding rod of the spring telescopic rod 7 corresponds to the insertion hole of the sliding sleeve, and then the worker inserts the insertion rod 641 into the insertion hole, so as to lock the adjacent supporting slides 424, thereby fixing the positions of the grinding roller 611 and the squeezing roller 612, and the three spring telescopic rods 7 provide triangular stable support for the grinding mechanism 6, thereby effectively absorbing and buffering the vibration during the grinding process.

[0049] See also Figure 2 , Figure 4 , Figure 5 and Figure 7 The driving unit 62 includes a third motor 621 fixedly mounted on the support slide 424 of the electric slide rail 422 , and the output end of the third motor 621 is connected to the shaft of the grinding roller 611 through a belt transmission.

[0050] During specific operation, after the grinding roller 611 is fitted with the half-shaft, the third motor 621 is started to rotate the grinding roller 611 through the belt, so that the grinding roller 611 grinds the half-shaft. At the same time, the second motor 523 is started to rotate the half-shaft through the limit plate 521, and the electric slide rail 422 is started to move the grinding roller 611 horizontally through the supporting slide 424, and move synchronously with the squeezing roller 612 below under the action of the spring telescopic rod 7. In this way, when the half-shaft is polished, the grinding roller 611 and the squeezing roller 612 will always implement three-point support on the shaft grinding part of the half-shaft, and the three-point support will form a stable support surface, which can effectively prevent the half-shaft from shaking or deflecting during the polishing process, ensure that the grinding roller 611 is in uniform contact with the surface of the half-shaft, and improve the polishing quality and efficiency.

[0051] See also Figure 2 , Figure 5 and Figure 7 The extrusion part 63 includes an extrusion assembly fixedly mounted on the support arm 421, the extrusion assembly on the support arm 421 with the electric slide rail 422 is composed of a support rod 631 fixedly mounted on the rear end surface thereof, and the remaining extrusion assemblies are composed of support rods 631 symmetrical about the corresponding limiting slide rail 423, and the end of the support rod 631 away from the corresponding support arm 421 is rotatably mounted with a rotating sleeve through a set torsion spring, and the rotating sleeve is fixedly mounted with left-right symmetrical extrusion rods 632, the support slide 424 of the electric slide rail 422 is fixedly mounted with left-right symmetrical first push rods 633, and the support slide 424 of the limiting slide rail 423 is fixedly mounted with left-right symmetrical second push rods 634.

[0052] During specific operation, when the support slide 424 with the grinding roller 611 moves from right to left, the support slide 424 will move synchronously under the action of the spring telescopic rod 7. When the support slide 424 is at the rightmost side, the first push rod 633 and the second push rod 634 at its right end will squeeze the extrusion rod 632 corresponding to the right end toward the side away from the semi-axis, and rotate the extrusion rod 632 on the left side with the rotating sleeve and the support rod 631 as the center point, so that the end of the left extrusion rod 632 away from the rotating sleeve is in contact with and squeezed by the outer ring wall of the semi-axis, and the extrusion rod 632 is made of elastically deformable material, so that at this time, the extrusion force applied by the end of the left extrusion rod 632 away from the rotating sleeve to the semi-axis is the largest. When the support slide 424 moves to the left, the extrusion force on the semi-axis gradually decreases. Until it reaches the center of the semi-axis, the extrusion rods 632 on both sides do not apply pressure to the semi-axis.

[0053] Then continue to move the support slide 424 to the left. At this time, the first push rod 633 and the second push rod 634 at the left end of the support slide 424 will squeeze the corresponding extrusion rod 632 at the left end toward the side away from the half-shaft, so that the end of the right extrusion rod 632 away from the rotating sleeve begins to contact and squeeze the outer ring wall at the other end of the half-shaft. Therefore, when the half-shaft is polished, the outer ring wall at the other end of the shaft rod part of the half-shaft can be adaptively circumferentially extruded according to the change of the polishing position, and the adaptive circumferential extrusion can adjust the support force in real time according to the polishing position, ensuring that the half-shaft remains stable during the polishing process and avoiding uneven polishing due to shaking. At the same time, the uniform distribution of support force can prevent the local area of ​​the half-shaft from being subjected to excessive stress, reduce the risk of stress concentration, improve the fatigue strength of the half-shaft and extend its service life.
