Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical processing, more particularly, to a boring device for fork-like parts of a transmission shaft. BACKGROUND

[0002] In the prior art, transmission shaft assemblies are widely used, for example, in the transmission of torque in the transmission systems of automobiles, engineering machinery, ships, large road maintenance machinery, oil machinery, etc. A medium-sized transmission shaft manufacturer produces more than 100,000 transmission shaft assemblies per year, and each transmission shaft assembly has four fork-like parts that need to be bored. The traditional positioning and machining method is prone to defects such as broken edges during boring, unstable position error, and long clamping time, which seriously affects production efficiency and product quality.

[0003] At present, the common boring clamping method is as follows: the fork-like part is placed on the tooling, then the part ear hole direction is aligned, the pressing plate is covered, then the nut is locked with a wrench, and finally the boring operation is performed with the tooling. It often takes several minutes to install and fix a part on the tooling for boring. After the boring of a single part is completed, the nut needs to be loosened with a wrench, the pressing plate needs to be removed, and the part needs to be taken out. The above process is time-consuming and labor-intensive. Therefore, the boring installation and disassembly of the part occupies more than half of the production time, resulting in extremely low boring efficiency of the transmission shaft parts. Moreover, the thickness of the upper and lower ear holes after boring is uneven, which not only affects the strength of the part, but also causes the problem of excessive residual unbalance of the transmission shaft assembly.

[0004] In summary, how to provide a tooling suitable for boring a large number of fork-like parts of a transmission shaft is a problem that needs to be solved by technicians in the field at present. SUMMARY

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please refer to Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the boring device for drive shaft fork-type parts provided by the present invention. Figure 2 for Figure 1 The main view; Figure 3 for Figure 1 Top view; Figure 4 for Figure 1 The left view; Figure 5 This is a schematic diagram of the installation of the extended parts.

[0032] The embodiment provides a transmission shaft fork part boring device, which comprises a reverse T-shaped base 1, a workpiece positioning flange plate 2 arranged on the vertical plate of the base 1, a V-shaped block 4 arranged opposite to the workpiece positioning flange plate 2 and used for clamping a part to be bored 3, two horizontal guide rods 5 arranged through the vertical plate, a first fixing plate 6 used for connecting the first ends of the two guide rods 5, a second fixing plate 7 and a driving device 8 used for driving the guide rods 5 to move laterally; the V-shaped block 4 is arranged on the second fixing plate 7, the second ends of the guide rods 5 are provided with mounting supports 12, the second fixing plate 7 and the mounting supports 12 are detachably connected, the vertical plate is provided with mounting holes, the first fixing plate 6 is provided with a through hole, and the positioning holes of the workpiece positioning flange plate 2, the mounting holes and the through hole are arranged in alignment.

[0033] It should be noted that a plurality of threaded holes can be arranged on the vertical plate, and the workpiece positioning flange plate is fixed on the vertical plate by bolts. The device only needs to replace the model of the workpiece positioning flange plate 2, so that the clamping operation of the parts to be bored 3 of different models can be performed, and the boring machining of workpieces of different shapes can be realized. Of course, the workpiece positioning flange plate 2 and the vertical plate of the base 1 can also be fixedly connected in other detachable connection modes, so as to be suitable for a plurality of fork accessories.

[0034] In actual application, the shape, structure, size, position, material and the like of the base 1, the workpiece positioning flange plate 2, the V-shaped block 4, the guide rod 5, the first fixing plate 6, the second fixing plate 7 and the driving device 8 can be determined according to actual conditions and actual needs.

[0035] When the transmission shaft fork part boring device is used, the part to be bored 3 is only placed on the workpiece positioning flange plate 2, the driving device 8 is operated to drive the guide rods 5 to move the second fixing plate 7 and the V-shaped block 4, so that the V-shaped block 4 contacts the part to be bored 3, thereby aligning the part mounting direction and clamping the part. Then, the boring operation of the part to be bored 3 can be performed, then the driving device 8 is controlled to operate reversely to drive the guide rods 5 to move reversely, so that the V-shaped block 4 is separated from the part to be bored 3, and then the part to be bored 3 is taken down, so as to complete the machining operation.

[0036] When a long part to be bored 3 needs to be machined, first, one side of the second fixed plate 7 and the mounting support 12 of the guide rod 5 can be opened to rotate outward to open the second fixed plate 7 and the V-shaped block 4, and then the long part to be bored 3 is placed in position through the positioning hole, the mounting hole and the through hole of the workpiece positioning flange plate 2. Then, the second fixed plate 7 and the V-shaped block 4 can be rotated inward again, and the second fixed plate 7 and the mounting support 12 of the guide rod 5 are connected and fixed. Then, the above steps can be repeated, the guide rod 5 is driven to move by the driving device 8 to clamp the part to be bored 3 for boring operation, and then the guide rod 5 is driven in the opposite direction to separate the V-shaped block 4 from the part to be bored 3. Finally, the part to be bored 3 is removed to complete the machining operation.

[0037] The device can position different types of transmission shaft fork parts through the installation of different workpiece positioning flange plates 2, and then bore the transmission shaft fork parts. Moreover, the driving device 8 controls the guide rod 5 to drive the V-shaped block 4 to move to clamp or loosen the part to be bored 3, so that the part to be bored 3 can be quickly clamped, bored and loosened. Since each part to be bored 3 can be machined by the device, the positioning direction of each part to be bored 3 is consistent, the clamping stability is good, the problem of uneven wall thickness of the part ear hole in the boring process is solved, the remaining unbalance after assembly is reduced, and the problem of low boring and clamping efficiency of the transmission shaft fork part is completely solved.

[0038] In summary, the transmission shaft fork part boring device provided by the present application can bore each type of transmission shaft fork part, and is suitable for assisting in boring a large number of transmission shaft fork parts.

[0039] In one embodiment, the driving device 8 includes two symmetrically distributed air cylinders 81, a pneumatic reversing valve 82 and a piston rod 83 for connecting the piston of the air cylinder 81 and the first fixed plate 6, and the pneumatic reversing valve 82 is provided with a control handle 84, and the two air cylinders 81 are located on the outer side of the two guide rods 5. That is, the two air cylinders 81 are spaced apart, and the spacing area is used to pass through the elongated part to be bored 3. The pneumatic reversing valve 82 is used to reverse the gas driving the air cylinder 81.

[0040] It should be noted that the two air cylinders 81 are symmetrically installed, which can realize parallel movement of the guide rod 5 driving the V-shaped block 4. Moreover, since the two air cylinders 81 are spaced apart, the first fixed plate 6 is provided with through holes aligned with the mounting holes, which can avoid the collision between the spline shaft part of the part to be bored 3 and the air cylinder 81 and the first fixed plate 6.

[0041] It should be noted that, only need to put the boring parts 3 on the workpiece positioning flange plate 2, operating the control handle 84 of pneumatic reversing valve 82, so that the piston and piston rod 83 of cylinder 81 extend, push the first fixed plate 6 and guide rod 5 movement, in turn can drive V block 4 and the arc end of boring parts 3 contact, to automatically align the part installation direction and clamp boring parts 3. When the boring operation of boring parts 3 is completed, the control handle 84 of pneumatic reversing valve 82 can be moved to realize the retraction of cylinder 81, push guide rod 5 movement, in turn drive V block 4 and the arc end of boring parts 3 apart, so as to take down boring parts 3.

[0042] When the longer boring parts 3 needs to be processed, the second fixed plate 7 and the mounting support 12 of guide rod 5 can be separated and the second fixed plate 7 can be rotated outward, then the boring parts 3 can be installed and the second fixed plate 7 can be closed, then the mounting support 12 of the second fixed plate 7 and the guide rod 5 can be fixed, and then the above processing operation steps can be repeated. Because the device can clamp and release the boring parts 3 very quickly, the purpose of improving production efficiency can be achieved.

[0043] In an embodiment, the base 1 is provided with two guide rod seats 9, the guide rod seat 9 is provided with a first through hole for passing through the guide rod 5, the vertical plate is provided with a second through hole for passing through the guide rod 5, and the first through hole and the second through hole are arranged in alignment. That is, when the guide rod 5 is installed on the base 1, the first through hole of the guide rod seat 9 must be coaxially aligned with the second through hole of the base 1, and then the guide rod 5 is fixed by using positioning pins 15 and bolts.

[0044] It should be noted that the base 1 is provided with two guide rod seats 9, and the guide rod seat 9 and the base 1 can be positioned by positioning pins 15 and fixed by bolts, that is, the guide rod seat 9 can be vertically fixed on the horizontal part of the base 1 by using positioning pins 15 and hexagonal bolts 16. Moreover, the second through hole on the vertical plate and the first through hole on the guide rod seat 9 are aligned to ensure that the guide rod 5 is placed horizontally, and then the guide rod 5 moves stably when the cylinder 81 operates. Moreover, the guide rod fixing nut 17 can be installed on the end of the guide rod 5 that passes through the first fixed plate 6, and the piston rod fixing nut 18 can be installed on the end of the piston rod 83 that passes through the first fixed plate 6.

[0045] In an embodiment, two cylinders 81 are connected by a gas pipe 20, the gas pipe 20 and the pneumatic reversing valve 82 are connected, the pneumatic reversing valve 82 is arranged on the valve support 10, and the valve support 10 is arranged on one side of the vertical plate.

[0046] It should be noted that the two cylinders 81 are connected through the air pipe 20, and the air pipe 20 and the pneumatic reversing valve 82 can be connected through the tee joint 21, and the end of the air pipe 20 can be provided with the air pipe joint 19. The working principle of the cylinder 81 and the pneumatic reversing valve 82 is that the forward and reverse movements of the piston of the cylinder 81 are driven by compressed air to drive the first fixed plate 6 to move forward and backward through the piston rod 83 of the piston to realize the quick clamping and loosening operation of the part 3 to be bored. That is, the automatic positioning and clamping operation of the part 3 to be bored can be realized through the pneumatic reversing valve 82.

[0047] In an embodiment, the second end of the guide rod 5 is provided with a mounting support 12, and the one end of the second fixed plate 7 and the mounting support 12 are both provided with an assembly hole for inserting a fixed pin 13; the second end of the other guide rod 5 is provided with a first buckle part 11, and the other end of the second fixed plate 7 is provided with a torsion spring 22 and a second buckle part 23 connected with the torsion spring 22, and the second buckle part 23 is provided with a handle member 24 on one side. The first buckle part 11 and the second buckle part 23 are in clamping cooperation, and the structure is as shown in Figure 3 、 Figure 4

[0048] Wherein, the torsion spring 22 and the second buckle part 23 can be connected through a pin shaft, that is, the pin shaft penetrates through one side of the second buckle part 23, the end of the pin shaft is connected with the elastic end of the torsion spring 22, the other elastic end of the torsion spring 22 is arranged on the second fixed plate 7, and the handle member 24 is connected with the second buckle part 23. Therefore, when the handle member 24 is moved outward, the second buckle part 23 can be driven to move outward, the pin shaft rotates, and the torsion spring 22 is deformed to store elastic force. After the handle member 24 is loosened, the pin shaft can be driven to rotate reversely and reset under the action of the elastic force of the torsion spring 22 to drive the second buckle part 23 to move inward until the first buckle part 11 is clamped and fixed.

[0049] It should be noted that the mounting support 12 is additionally arranged between the second fixed plate 7 and the guide rod 5, the one end of the second fixed plate 7 and the mounting support 12 are both provided with an assembly hole for inserting a fixed pin 13, and the end of the other guide rod 5 is provided with a first buckle part 11, and the other end of the second fixed plate 7 is provided with a torsion spring 22 and a second buckle part 23 connected with the torsion spring 22, and the first buckle part 11 and the second buckle part 23 are in clamping cooperation.

[0050] Therefore, when the second fixed plate 7 needs to be opened, the handle member 24 can be pulled or pried outward to make the second fixed plate 7 flip outward around the fixed pin 13 to be opened, and then the handle member 24 can be loosened, and the second buckle part 23 can be reset and automatically clamped and cooperated with the first buckle part 11 under the action of the torsion spring 22 to quickly close the second fixed plate 7.

[0051] ​That is, when a longer part to be bored 3 needs to be processed, the second fixing plate 7 and one end of the guide rod 5 can be separated by moving the handpiece 24 outward, and the second fixing plate 7 is rotated outward, and then the part to be bored 3 is installed, the second fixing plate 7 is closed, the second fixing plate 7 and the guide rod 5 are connected through the buckle structure (that is, the first buckle part 11 and the second buckle part 23), and then the above processing operation steps are repeated. Therefore, the speed of clamping and loosening the part to be bored 3 of the device is particularly fast, and only the handpiece 24 needs to be moved outward or loosened, so that the device can achieve the purpose of improving production efficiency.

[0052] In one embodiment, the four corners of the base 1 are respectively provided with mounting grooves 14 for connecting with the machine tool workbench. Therefore, when the base 1 is transferred to the machine tool workbench, it can be fixed with the machine tool workbench in the four mounting grooves 14 of the base 1, and then the part to be bored 3 is bored by the device.

[0053] In one embodiment, one side of the V-shaped block 4 is a horizontal surface connected with the second fixing plate 7, and the other side of the V-shaped block 4 is a V-shaped surface for accommodating the circular arc part of the part to be bored 3, and the V-shaped surface is a circular arc transition surface. Therefore, the V-shaped surface of the V-shaped block 4 can be in contact with the circular arc transition surface of the part to be bored 3 to avoid damage to the part to be bored 3, and the installation direction of the part to be bored 3 can be quickly positioned.

[0054] In order to further illustrate the use method of the transmission shaft fork part boring device provided by the present application, it will be illustrated by examples.

[0055] Step 1, before work, determine the model of the part to be bored 3, select the workpiece positioning flange plate 2 corresponding to the part, and install and fix the workpiece positioning flange plate 2 on the vertical plate of the base 1;

[0056] Step 2, move the control handle 84 of the pneumatic reversing valve 82 clockwise once, the compressed air pushes the piston of the pneumatic cylinder 81 to move, the piston rod 83 of the pneumatic cylinder 81 is retracted to drive the second fixing plate 7 to move, so as to drive the guide rod 5 and the V-shaped block 4 to move to one end of the part to be bored 3;

[0057] Step 3, install the part to be bored 3 on the workpiece positioning flange plate 2, move the control handle 84 of the pneumatic reversing valve 82 counterclockwise once, the compressed air pushes the piston of the pneumatic cylinder 81 to move, the piston rod 83 of the pneumatic cylinder 81 pushes the guide rod 5 to drive the V-shaped block 4 to move to one end of the second fixing plate 7, the V-shaped block 4 is in contact with the outer circular arc of the part to be bored 3 to clamp the part to be bored 3 with the workpiece positioning flange plate 2;

[0058] Step 4, start the machine tool to cut, after cutting, stop the machine tool operation, then, use the inner diameter gauge to measure the boring size, when the first boring part 3 reaches the process requirement, repeat the above step 2, take down the workpiece.

[0059] Through the above steps 2, 3, 4, the continuous machining operation of the boring part 3 can be realized. Because the speed of clamping and loosening the boring part 3 is particularly fast, the purpose of improving production efficiency can be achieved. For example, before the implementation of the device, it takes 2.5-3 hours to replace the product adjustment tooling, but after the implementation of the device, only two bolts on the workpiece positioning flange plate 2 are removed by using an inner hex wrench, the connecting surface is wiped clean with a clean cloth, and the required workpiece positioning flange plate 2 is installed and fixed. The replacement time is about 15 minutes, which effectively shortens the replacement product adjustment tooling time.

[0060] And before the pneumatic device is used, it takes 3 minutes to lock a single boring part 3 by using a pressing plate, a bolt and a nut, and the processing time is 2 minutes, and 11-12 boring parts can be processed per hour. However, by using the V-shaped block 4 to control the clamping direction of the boring part 3, the process of clamping the boring part 3 by using the pneumatic device only takes 30 seconds, and the processing time is 2 minutes, and about 23-24 boring parts 3 can be processed per hour, which improves the production efficiency by 50% on the original basis, and effectively improves the production efficiency.

[0061] In addition, the device can quickly clamp and loosen the boring of various types of transmission shaft fork parts, and the positioning direction of the boring part 3 is consistent, the clamping stability is good, effectively solves the problem of uneven wall thickness of the ear hole of the part during boring, reduces the remaining unbalance of the transmission shaft assembly after assembly, and effectively solves the low boring and clamping efficiency of the transmission shaft fork part.

[0062] It should be noted that the first fixed plate 6 and the second fixed plate 7, the first end and the second end, the first buckle part 11 and the second buckle part 23, the first through hole and the second through hole mentioned in the present application are only for distinguishing the different positions, and there is no sequence.
