Description

Technical Field

[0001] The present invention relates to the technical field of forging part grinding, and specifically to an automatic forging part grinding device. Background Art

[0002] The half shaft (as Figure 8 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, defects such as burrs, scale, cracks, and folds will occur on its surface. Therefore, before using the half shaft, the surface of the half shaft needs to be polished to improve the surface finish of the half shaft and remove the defects on its surface, thereby reducing the contact friction and wear between the half shaft and the bearing and other components, and improving the transmission efficiency of the half shaft.

[0003] Currently, when grinding the half shaft, the two ends of the half shaft need to be fixed in the fixture first, and then the grinding roller is started and the half shaft fixed in the fixture is rotated. Then, the half shaft is horizontally moved so that the grinding roller can comprehensively grind the surface of the half shaft, thus completing the grinding of the half shaft. The above grinding method has the following disadvantages: 1. During the above operation process, when the grinding roller grinds one side surface of the half shaft, it does not provide stable support for the other side of the half shaft, making the half shaft prone to shaking or deviation during the grinding process, resulting in the grinding roller being unable to evenly contact the surface of the half shaft, and further resulting in inconsistent surface roughness of the half shaft after grinding, affecting 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 one end deviating from the center of the half shaft, the pressure exerted by the grinding roller will be concentrated on the end deviating from the center, and there is no support on the other side, resulting in uneven stress on the half shaft, making the half shaft prone to bending or local deformation, affecting its geometric accuracy and straightness. Moreover, the pressure of the grinding roller being concentrated on the end deviating from the center will cause excessive stress in its local area, forming a stress concentration area on the surface of the half shaft, thereby reducing its fatigue strength and shortening its service life.

[0037] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 , the alignment portion 41 includes a first alignment disc 411 fixedly installed on the left end face of the first sliding seat 2 and having a cavity inside. Three first sliding channels 412 extending radially along its circumference are uniformly penetrated through the left end face of the first alignment disc 411. Inside the first alignment disc 411, a lead screw 4% corresponding to the first sliding channel 412 is rotatably installed through a bearing seat.

[0038] Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5and Figure 7 The supporting part 42 includes a supporting arm 421 fixedly installed at the left end of the first slider 413. An electric slide rail 422 is fixedly installed on the lower end surface of the upper supporting arm 421. Limiting slide rails 423 are fixedly installed on one side wall of other supporting arms 421 close to the upper supporting arm 421. A supporting carriage 424 is fixedly installed on the moving end of the electric slide rail 422, and the supporting carriage 424 is also slidably installed in the limiting slide rail 423. A positioning rod is fixedly installed on the left end surface of the supporting arm 421. The spring telescopic rod 7 consists of a sliding sleeve, a sliding rod slidably installed in the sliding sleeve, and a tension spring between the sliding rod and the sliding sleeve. Insertion holes are jointly opened on the sliding rod and the sliding sleeve, and the spring telescopic rods 7 are jointly hinged between adjacent supporting carriages 424.

[0039] Please refer to Figure 3 and Figure 4 The clamping part 43 includes a three-jaw chuck 431 fixedly installed at the center of the left end surface of the first alignment disk 411. A pressing roller 432 is rotatably installed at the clamping end of the three-jaw chuck 431 through a provided support frame.

[0040] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The matching part 51 includes a second alignment disk 511 fixedly installed on the right end surface of the second slide base 3 and coaxial with the first alignment disk 411. Second slide ways 512 corresponding to the first slide ways 412 are opened on the right end surface of the second alignment disk 511. Second sliders 513 are slidably installed in the second slide ways 512. Insertion slots for mating and inserting with the corresponding positioning rods are opened on the right end surfaces of the second sliders 513. Springs are fixedly installed between the second sliders 513 and the second slide ways 512.

[0041] Please refer to Figure 1 and Figure 6 The rotating part 52 includes a limiting disk 521 installed at the center of the right end surface of the second alignment disk 511 through a bearing. Limiting protrusions for restricting part of the half shaft disk are arranged on the right end surface of the limiting disk 521. A connecting rod 522 passing through the right end surface of the second alignment disk 511 is installed in the second slide base 3 through a bearing. The right end of the connecting rod 522 is fixedly connected to the limiting disk 521. A second motor 523 with an output end fixedly connected to the connecting rod 522 is fixedly installed on the second slide base 3.

[0042] During specific operation, when the half shaft needs to be polished, first place the disk part of the half shaft to be polished at the limiting disk 521, and at the same time pass the limiting protrusion through the through hole of the disk part, so that the disk part of the half shaft is in contact with the right end surface of the limiting disk 521, thereby completing the placement of the half shaft.

[0043] Next, move the second sliding seat 3 with the half shaft closer to the first sliding seat 2 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 sliding seat 3 and the first sliding seat 2 can be manually rotated with an electric rotary tool to fix the second sliding seat 3 and the first sliding seat 2 on the slide rail to prevent them from sliding. Then, through the three-jaw chuck 431, its clamping end is made to 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 contacting the half shaft will not hinder the rotation of the half shaft, thus completing the fixation of the half shaft.

[0044] During the process of the second sliding seat 3 approaching the first sliding seat 2, the alignment rod on the support arm 421 will insert into the slot of the second slider 513. Then, start the first motor 415 to synchronously rotate several screw rods 414 through the cooperation of the second bevel gear and the first bevel gear, so that the three support arms 421 bring the grinding mechanism 6 closer to the half shaft through the first slider 413. When the support arm 421 with the grinding part 61 contacts the half shaft, the first motor 415 can be stopped from running.

[0045] Please refer to Figure 2 、 Figure 5 and Figure 7 As shown in, the grinding part 61 includes a grinding roller 611 rotatably mounted on the support carriage 424 of the electric slide rail 422 through a set shaft rod, and a pressing roller 612 is rotatably mounted on the support carriage 424 of the limit slide rail 423 through a set shaft rod.

[0046] Please refer to Figure 2 、 Figure 5 and Figure 7 As shown in, the locking part 64 includes a plug rod 641 inserted into the socket of the spring telescopic rod 7.

[0047] During specific operation, during the process of the three support arms 421 bringing the grinding mechanism 6 closer to the half shaft synchronously, the grinding roller 611 and the pressing roller 612 will contact the outer ring wall of the half shaft synchronously through the support carriage 424, so that the grinding roller 611 and the pressing roller 612 implement three-point support on the half shaft.

[0048] During this process, the adjacent support carriages 424 will compress the corresponding spring telescopic rods 7. When the grinding roller 611 and the pressing roller 612 contact the half shaft, the sliding rod of the spring telescopic rod 7 corresponds to the socket of the sliding sleeve. Then, the worker inserts the plug rod 641 into the socket to lock the adjacent support carriages 424, thereby fixing the positions of the grinding roller 611 and the pressing roller 612. The three spring telescopic rods 7 provide triangular stable support for the grinding mechanism 6 to effectively absorb and buffer the vibration during the grinding process.

[0049] Please refer to Figure 2 、 Figure 4 、 Figure 5 andFigure 7 , the driving part 62 includes a third motor 621 fixedly installed on the support carriage 424 of the electric slide rail 422. The output end of the third motor 621 is connected to the shaft rod of the grinding roller 611 through a belt drive provided.

[0050] During specific operation, after the grinding roller 611 is in contact with the half shaft, start the third motor 621 to rotate the grinding roller 611 through the belt, so that the grinding roller 611 grinds the half shaft. At the same time, start the second motor 523 to rotate the half shaft through the limit disc 521, and at the same time start the electric slide rail 422 to horizontally move the grinding roller 611 through the support carriage 424, and under the action of the spring telescopic rod 7, synchronously move the lower pressing roller 612 below. In this way, when grinding the half shaft, the grinding roller 611 and the pressing roller 612 will always implement three-point support on the grinding part of the shaft rod of the half shaft, and the three-point support will form a stable support surface, effectively preventing the half shaft from shaking or shifting during the grinding process, ensuring uniform contact between the grinding roller 611 and the surface of the half shaft, and improving the grinding quality and efficiency.

[0051] Please refer to Figure 2 , Figure 5 and Figure 7 , the pressing part 63 includes a pressing component fixedly installed on the support arm 421. The pressing component on the support arm 421 with the electric slide rail 422 is composed of a support rod 631 fixedly installed on its rear end face, and the rest of the pressing components are composed of support rods 631 symmetrically arranged with respect to the corresponding limit slide rail 423. One end of the support rod 631 far from the corresponding support arm 421 is rotatably installed with a rotating sleeve through a torsion spring provided, and symmetrically arranged pressing rods 632 are fixedly installed on the rotating sleeve. Symmetrically arranged first push rods 633 are fixedly installed on the support carriage 424 of the electric slide rail 422, and symmetrically arranged second push rods 634 are fixedly installed on the support carriage 424 of the limit slide rail 423.

[0052] During specific operation, when the support carriage 424 with the grinding roller 611 moves from right to left, the support carriage 424 will move synchronously under the action of the spring telescopic rod 7. When the support carriage 424 is at the rightmost side, the first push rod 633 and the second push rod 634 at its right end will squeeze the corresponding pressing rod 632 at the right end to the side away from the half shaft, and rotate the pressing 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 pressing rod 632 far from the rotating sleeve contacts and squeezes the outer ring wall of the half shaft, and the pressing rod 632 is made of an elastically deformable material, so that the squeezing force exerted by the end of the left pressing rod 632 far from the rotating sleeve on the half shaft is the largest at this time. When the support carriage 424 moves to the left, the squeezing force on the half shaft gradually decreases until it reaches the center of the half shaft, and neither of the two pressing rods 632 applies pressure to the half shaft.

[0053] Subsequently, continue to move the support carriage 424 to the left. At this time, the first push rod 633 at the left end of the support carriage 424 and the second push rod 634 will squeeze the corresponding extrusion rod 632 at the left end to 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. When grinding the half shaft, the outer ring wall at the other end of the half shaft rod part can be adaptively circumferentially squeezed according to the change of the grinding position. Moreover, the adaptive circumferential squeezing can adjust the support force in real time according to the grinding position, ensure the stability of the half shaft during grinding, avoid uneven grinding caused by shaking. At the same time, the uniform support force distribution can prevent local areas of the half shaft from bearing excessive stress, reduce the risk of stress concentration, improve the fatigue strength of the half shaft and extend its service life.

[0054] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
