Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a rod end bearing seat fixture and a rod end bearing seat processing device. Background Technology

[0002] The rod end bearing housing is a ring-shaped part with a relatively long tail. Generally, machining such parts requires first machining the inner hole of the ring, then machining a center hole at one end of the tail. Using the inner hole of the ring as a reference, a live center is used to hold the rod end bearing housing in place. Finally, the required shape of the tail end of the rod end bearing housing is machined on a lathe. During machining, the center hole machined at the tail end serves only as a positioning reference and has no other purpose. This step of machining the center hole at the tail end obviously increases the production time required for the rod end bearing housing and reduces machining efficiency. Utility Model Content

[0003] The main objective of this invention is to provide a rod end bearing housing fixture and a rod end bearing housing processing device to solve the problem of low processing efficiency of rod end bearing housings in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a rod end bearing seat clamp is provided, comprising: a base; a mandrel assembly, the mandrel assembly including a seat body and a hook claw, the hook claw having a hook-shaped structure, the hook-shaped structure having a first limiting portion, the seat body being fixedly connected to the base, the seat body having a second limiting portion; the mandrel assembly having a first position, when the mandrel assembly is in the first position, the seat body is inserted into the annular structure of the rod end bearing seat, the first limiting portion abuts against the horizontal outer wall surface of the annular structure, and the second limiting portion abuts against the axial inner wall surface of the annular structure, thereby limiting the rod end bearing seat.

[0005] Furthermore, the rod end bearing housing fixture also includes a positioning element, which is mounted on the base and located on one side of the spindle assembly. The positioning element has a mounting groove, and the tail of the rod end bearing housing is placed in the mounting groove.

[0006] Furthermore, the seat body has a through hole in the axial direction and a groove in the circumferential direction; the hook claw is rotatably connected to the groove.

[0007] Furthermore, the mandrel assembly also includes: a directional shaft, which is installed in the through hole and has a sliding part; a drive rod, which is installed in the through hole and connected to the directional shaft, and drives the directional shaft to slide along the axial direction of the through hole; and a sliding pin, which is connected to one end of the hook claw, is installed in the sliding part, and slides within the sliding part.

[0008] Furthermore, the mandrel assembly includes multiple sliding pins and hook claws, with every two sliding pins and every two hook claws arranged symmetrically.

[0009] Furthermore, the mandrel assembly also has a second position, in which the mandrel assembly avoids the rod end bearing seat, allowing the annular structure of the rod end bearing seat to fit into the mandrel assembly.

[0010] Furthermore, the rod end bearing housing fixture also includes a drive assembly, which is drivenly connected to the spindle assembly, and the drive assembly drives the spindle assembly to move.

[0011] Furthermore, the drive assembly includes: a piston rod connected to a drive rod, the piston rod driving the drive rod to move axially along the through hole; a pneumatic component and a gas passage, the gas passage being connected to the pneumatic component, through which gas is introduced or discharged to the pneumatic component to drive the piston rod to move.

[0012] Furthermore, the mounting groove has an open side and a protruding wall. The open side avoids the rod end bearing seat, allowing the rod end bearing seat to be placed on the positioning element, while the protruding wall limits the rod end bearing seat.

[0013] On the other hand, this utility model also provides a rod end bearing housing processing device, including the above-mentioned rod end bearing housing fixture.

[0014] This invention, by setting a mandrel assembly including a seat and a hook claw, allows the mandrel assembly to engage with the second limiting part of the seat and the first limiting part of the hook claw to limit the rod end bearing seat from two directions, ensuring reliable positioning of the rod end bearing seat. The hook-shaped structure of the hook claw can better apply clamping force to the rod end bearing seat when the second limiting part abuts against the horizontal outer wall surface of the rod end bearing seat, ensuring reliable positioning of the rod end bearing seat. When the mandrel assembly is in the first position, the annular structure of the rod end bearing seat is sleeved on the mandrel assembly, the first limiting part of the hook claw abuts against the horizontal outer wall surface of the annular structure of the rod end bearing seat, and the second limiting part of the seat abuts against the axial inner wall surface of the annular structure to limit the rod end bearing seat. This ensures reliable positioning of the rod end bearing seat without the need for additional machining of a center hole to assist in positioning the rod end bearing seat, simplifying the production process and improving the processing efficiency of the rod end bearing seat.

[0028] The existing rod end bearing housing requires a center hole to be machined at the tail end as a positioning reference for the machining process. The center hole has no other purpose, which obviously increases the time required for part production and reduces machining efficiency.

[0029] This invention provides a rod end bearing seat fixture and a rod end bearing seat processing device, which solves the problem of low processing efficiency of rod end bearing seats in the prior art.

[0030] like Figures 1 to 7 As shown, this embodiment provides a rod end bearing seat clamp, including: a base 10 and a spindle assembly 20; the spindle assembly 20 includes a seat body 21 and a hook claw 24, the hook claw 24 has a hook-shaped structure, the hook-shaped structure has a first limiting part, the seat body 21 is fixedly connected to the base 10, and the seat body 21 has a second limiting part; the spindle assembly 20 has a first position, when the spindle assembly 20 is in the first position, the seat body 21 passes through the annular structure of the rod end bearing seat 50, the first limiting part abuts against the horizontal outer wall surface of the annular structure, and the second limiting part abuts against the axial inner wall surface of the annular structure 51, so as to limit the rod end bearing seat 50.

[0031] This embodiment includes a spindle assembly 20 comprising a seat 21 and a hook claw 24. The spindle assembly 20 can cooperate with the second limiting part of the seat 21 and the first limiting part of the hook claw 24 to limit the rod end bearing seat 50 from two directions, ensuring reliable limiting of the rod end bearing seat 50. The hook-shaped structure of the hook claw 24 can better apply clamping force to the rod end bearing seat 50 when the second limiting part abuts against the horizontal outer wall surface of the rod end bearing seat 50, ensuring reliable limiting of the rod end bearing seat 50. When the spindle assembly 20 is in the first position, the annular structure 51 of the rod end bearing seat 50 is sleeved on the spindle assembly 20. The first limiting part of the hook claw 24 abuts against the horizontal outer wall surface of the annular structure 51 of the rod end bearing seat 50, and the second limiting part of the seat body 21 abuts against the axial inner wall surface of the annular structure 51 to limit the rod end bearing seat 50. This ensures that the rod end bearing seat 50 is reliably limited, and there is no need to additionally machine a center hole to assist in limiting the rod end bearing seat 50, which simplifies the production process and improves the processing efficiency of the rod end bearing seat 50.

[0032] In this embodiment, the outer wall surface of the seat 21 serves as the second limiting part. The seat 21 can be a hollow cylinder with an outer diameter slightly smaller than the inner diameter of the annular structure 51, so that the outer wall surface of the seat 21 abuts against the axial inner wall surface of the annular structure 51 to limit the rod end bearing seat 50.

[0033] In this embodiment, the lower surface of the hook-shaped structure is the first limiting part. When the spindle assembly 20 is in the first position, the first limiting part abuts against the horizontal outer wall of the annular structure 51 of the rod end bearing seat 50, thereby achieving reliable limiting of the rod end bearing seat 50.

[0034] The rod end bearing seat clamp of this embodiment can also be used to clamp bearings with a ring structure 51, such as limit joint bearings.

[0035] In this embodiment, the rod end bearing seat fixture is placed vertically from bottom to top. The base 10 includes an intermediate plate 11 and a connecting plate 12. The connecting plate 12 is fixedly connected to the intermediate plate 11 by bolts, and a spindle assembly is fixed on one side of the connecting plate 12.

[0036] like Figure 4 As shown, the seat 21 of this embodiment has a through hole in the axial direction and a groove in the circumferential direction; the hook claw 24 is rotatably connected to the groove, and the hook claw 24 can rotate to the first position to abut against the rod end bearing seat 50, thereby limiting the rod end bearing seat 50.

[0037] like Figure 4 As shown, the mandrel assembly 20 of this embodiment further includes: a directional shaft 22, a drive rod 23, and a sliding pin 25. The directional shaft 22 is installed in the through hole and has a sliding portion. The drive rod 23 is installed in the through hole and connected to the directional shaft 22. The drive rod 23 and the directional shaft 22 can be connected and fixed by bolts or other parts. The drive rod 23 drives the directional shaft 22 to slide along the axial direction of the through hole. The hook claw 24 is rotatably connected to the groove. The sliding pin 25 is connected to one end of the hook claw 24 and is installed in the sliding portion, sliding within the sliding portion. The up-and-down movement of the drive rod 23 in the through hole can drive the directional shaft 22 to slide up and down in the through hole. The up-and-down movement of the directional shaft 22 will drive the sliding pin 25 to slide within the sliding portion. Since the hook claw 24 is rotatably connected to the groove, the movement of the sliding pin 25 will drive the hook claw 24 to rotate. The hook claw 24 opens or closes until the mandrel assembly 20 reaches the first position.

[0038] In this embodiment, the sliding part can be a horizontal elongated hole structure opened on the directional shaft 22. Specifically, it can be an elongated hole or a rectangular hole. The long side of the elongated hole extends circumferentially along the seat 21, and the short side of the elongated hole extends axially along the seat 21.

[0039] like Figure 4As shown, the spindle assembly 20 of this embodiment also includes a rotating shaft 26. A mounting hole is provided in the middle of the hook claw 24. After the rotating shaft 26 passes through the mounting hole, the part of the rotating shaft 26 protruding from the hook claw 24 is installed on the side wall of the groove, so that the hook claw 24 is installed in the groove. The rotating shaft 26 is interference-fitted with the seat 21 and cannot be rotated after assembly. The rotating shaft 26 and the hook claw 24 are clearance-fitted, and the hook claw 24 can swing around the rotating shaft 26.

[0040] like Figure 5 As shown, in this embodiment, one end of the hook claw 24 is provided with a mounting part. The sliding pin 25 is connected to the hook claw 24 through the mounting part, and the sliding pin 25 and the hook claw 24 are press-fitted and fixedly connected. The part of the sliding pin 25 protruding from the hook claw 24 passes into the sliding part and can move within the sliding part. When the sliding pin 25 moves in the sliding part, since the hook claw 24 is fixedly connected to the seat 21 and can only rotate, the horizontal movement of the sliding pin 25 in the sliding part will be converted into the rotation of the hook claw 24, causing the hook claw 24 to open or close until the spindle assembly 20 reaches the first position and the second position. When the hook claw 24 opens to abut against the rod end bearing seat 50 under the drive of the sliding pin 25, the spindle assembly 20 reaches the first position; when the hook claw 24 closes to the circumferential side of the seat 21 under the drive of the sliding pin 25, the spindle assembly 20 reaches the second position.

[0041] In this embodiment, the sliding pin 25 can be a long columnar structure, specifically a cylinder or the like. Alternatively, the sliding pin 25 can be implemented by welding two columnar structures to the symmetrical sides of one end of the hook claw 24, or by machining two symmetrical columnar structures at one end of the hook claw 24 during processing.

[0042] In this embodiment, the hook claw 24 has a sliding pin 25 at one end and a hook-shaped structure at the other end, with a rotating shaft 26 in the middle. The sliding pin 25 slides within the sliding part, causing the hook claw 24 to rotate around the rotating shaft 26, thus opening or closing the hook claw 24. When the hook claw 24 is opened until the first limiting part abuts against the horizontal outer wall of the annular structure 51, i.e., when the spindle assembly 20 is in the first position, the rod end bearing seat 50 is limited by the spindle assembly 20. Furthermore, since the rod end bearing seat 50 is placed horizontally on the rod end bearing seat fixture, the first limiting part of the hook claw 24 abuts against the horizontal upper wall of the annular structure 51 of the rod end bearing seat 50.

[0043] like Figure 4 and Figure 6As shown, the spindle assembly 20 of this embodiment includes multiple sliding pins 25 and hook claws 24, with each pair of sliding pins 25 and each pair of hook claws 24 symmetrically arranged; correspondingly, there are also multiple sliding parts and rotating shafts 26, with each pair of sliding parts and each pair of rotating shafts 26 symmetrically arranged. That is, the sliding pins 25, hook claws 24, sliding parts, and rotating shafts 26 are arranged in groups, and multiple groups are arranged, with each pair of groups symmetrically arranged. Taking the arrangement of two groups of sliding pins 25, hook claws 24, sliding parts, and rotating shafts 26 as an example, the drive rod 23 drives the directional shaft 22 to move. The movement of the directional shaft 22 will cause the two sliding pins 25 to slide in the two sliding parts respectively. The two sliding pins 25 will cause the two hook claws 24 to rotate around the rotating shaft 26 respectively, so that the two hook claws 24 open at the same time and the first limiting part abuts against the horizontal outer wall surface of the annular structure 51 of the rod end bearing seat 50. The two hook claws 24 abut against the limiting rod end bearing seat 50 together, which improves the reliability of the limiting of the rod end bearing seat 50.

[0044] like Figure 7 As shown, in this embodiment, the spindle assembly 20 also has a second position. When the spindle assembly 20 is in the second position, the hook claw 24 retracts to a position that does not protrude from the circumferential side of the seat body 21. The spindle assembly 20 avoids the rod end bearing seat 50, so that the annular structure 51 of the rod end bearing seat 50 can be fitted into the spindle assembly 20, so that the spindle assembly 20 can subsequently limit the rod end bearing seat 50.

[0045] like Figure 1 and Figure 3 As shown, the rod end bearing seat fixture of this embodiment also includes a drive assembly, which is drivenly connected to the mandrel assembly 20. The drive assembly drives the mandrel assembly 20 to move. The drive assembly drives the mandrel assembly 20 to a first position, so that the first limiting part and the second limiting part of the mandrel assembly 20 abut against the horizontal outer wall surface and the axial inner wall surface of the annular structure, respectively, fixing the rod end bearing seat 50 and achieving the limiting of the rod end bearing seat 50. By driving the mandrel assembly 20 to move through the drive assembly, the mandrel assembly 20 can reach the first position and limit the rod end bearing seat 50. It is not necessary to manually clamp the rod end bearing seat 50 to complete the limiting of the rod end bearing seat 50, which improves the automation level of the rod end bearing seat 50 processing, can significantly reduce the operator's workload, shorten the clamping time, and will also significantly improve the production efficiency of the process.

[0046] like Figure 1 and Figure 3As shown, the drive assembly in this embodiment includes a piston rod, a pneumatic component 31, and a gas channel 32. The piston rod is connected to a drive rod 23, and the piston rod drives the drive rod 23 to move axially along the through hole. The gas channel 32 is connected to the pneumatic component 31, which can be a cylinder. Gas is introduced into or discharged from the pneumatic component 31 through the gas channel 32 to drive the piston rod to move. When compressed air is introduced into the pneumatic component 31 through the gas channel 32, the piston rod extends and drives the drive rod 23 connected to it to move upward along the through hole, thereby driving the directional shaft 22 to slide upward and causing the hook claw 24 to open. When the compressed air in the pneumatic component 31 is discharged through the gas channel 32, the piston rod retracts and drives the drive rod 23 connected to it to move downward along the through hole, thereby driving the directional shaft 22 to slide downward and causing the hook claw 24 to retract.

[0047] like Figures 1 to 3 As shown, the gas channel 32 in this embodiment includes a pneumatic connector 33, a pneumatic elbow 34, a hose 35, and a toggle-type pneumatic elbow 36. External compressed air is introduced through the pneumatic connector 33 and then connected to the cylinder through the pneumatic elbow 34, hose 35, and toggle-type pneumatic elbow 36. Introducing and venting compressed air controls the extension and retraction of the cylinder. Multiple gas channels 32 can be provided; this embodiment uses two gas channels 32 as an example, serving as the intake and exhaust channels for compressed air. The pneumatic connector 33 in this embodiment can be connected to a machine tool. After compressed air is introduced into the machine tool, the extension and retraction of the cylinder can be controlled. Pneumatic control eliminates the need for manual clamping, provides stable and reliable clamping force, and completes the clamping action simply by extending the cylinder. No auxiliary devices such as pressure caps or open washers are required. The workpiece can be removed after releasing the cylinder without additional operation, simplifying the production process and improving the processing efficiency of the rod end bearing seat 50.

[0048] In this embodiment, a vent is also provided on the transition plate 11, and a pneumatic connector 33 is installed in the vent. The compressed air of the machine tool is connected to the rod end bearing seat fixture through two pneumatic connectors 33. The two connectors are used for air intake and exhaust respectively. The pneumatic connectors 33 are connected to the cylinder through a pneumatic elbow 34, a hose 35, and a toggle pneumatic elbow 36. The cylinder is fixed to the other side of the connecting plate 12. Pneumatic control is adopted, eliminating the need for manual clamping. The clamping force is stable and reliable. The rod end bearing seat 50 is fixed by simply pushing out the cylinder. No auxiliary devices such as pressure caps or open washers are required. The rod end bearing seat 50 can be removed after releasing the cylinder without any additional operation.

[0049] As can be seen from the above, along the axial direction, a spindle assembly is fixed on one side of the connecting plate 12, and a cylinder is fixed on the other side; in this embodiment, an opening is made on the mounting plate, and the cylinder piston rod is connected to the spindle assembly through the opening on the connecting plate 12, and fixed with a flat washer and a round nut.

[0050] like Figure 1 As shown, the rod end bearing seat fixture of this embodiment also includes a positioning element 40, which is installed on the base 10. Specifically, the positioning element 40 is installed at the horizontal end of the connecting plate 12. The positioning element 40 is disposed on one side of the spindle assembly 20 and has a mounting groove. When the annular structure 51 of the rod end bearing seat 50 is sleeved on the spindle assembly 20, the tail 52 of the rod end bearing seat 50 can be placed in the mounting groove, so that the tail 52 of the rod end bearing seat 50 is limited to the mounting groove and cannot move in the horizontal direction, further ensuring the reliability of the rod end bearing seat 50's positioning. It should be noted that the part placed in the mounting groove is the connection between the annular structure 51 and the tail 52, that is, the middle part of the rod end bearing seat 50, while the end of the tail 52 of the rod end bearing seat 50 needs to be exposed for subsequent processing steps. By limiting the tail 52 to the mounting groove, the process of machining the center hole can be eliminated, simplifying the production process and improving the processing efficiency of the rod end bearing seat 50. By using the inner hole of the annular structure 51 of the rod end bearing seat 50, the end face of the rod end bearing seat 50, and the outer circle of the tail 52 of the rod end bearing seat 50 as positioning references, there is no need to machine a center hole, which simplifies the production process and has a significant effect on cost reduction and efficiency improvement.

[0051] like Figure 3 As shown, the mounting groove in this embodiment has an open side and a protruding wall. The open side avoids the rod end bearing seat 50, allowing the rod end bearing seat 50 to be placed on the positioning member 40. The protruding wall limits the rod end bearing seat 50. The positioning member 40 is roughly U-shaped. After the rod end bearing seat 50 is placed in the mounting groove, the protruding wall can limit the horizontal movement of the rod end bearing seat 50. The distance between the two protruding walls is slightly larger than the connection between the tail 52 of the rod end bearing seat 50 and the annular structure 51, so that the rod end bearing seat 50 can be held in place by the two protruding walls after being placed in the mounting groove, improving the reliability of the rod end bearing seat 50's positioning. Since the annular structure 51 of the seat body 21 and the rod end bearing seat 50 is a ring-within-a-cylinder structure, it is easier for them to rotate relative to each other. By setting the protruding wall, the rod end bearing seat 50 can be further limited, improving the reliability of the rod end bearing seat 50's positioning. No additional machining of the center hole is required, reducing equipment and labor input, simplifying the production process, and having a significant cost reduction and efficiency improvement effect.

[0052] This embodiment also provides a rod end bearing housing processing device, including the rod end bearing housing fixture described above. After the rod end bearing housing 50 is limited and fixed by the rod end bearing housing fixture, the machine tool can be started to process the tail 52 of the rod end bearing housing 50.

[0053] The machining process of the rod end bearing housing 50 in this embodiment is as follows:

[0054] 1. Operate the machine tool to discharge compressed air, causing the cylinder to retract. At this time, the hook claw 24 retracts to the side that does not protrude from the outer side of the seat 21, that is, the spindle assembly 20 is in the second position.

[0055] 2. The annular structure 51 of the rod end bearing seat 50 is fitted onto the spindle assembly 20, the seat body 21 abuts against the axial inner wall surface of the annular structure 51, and the tail 52 of the rod end bearing seat 50 is inserted into the mounting groove of the positioning member 40.

[0056] 3. Operate the machine tool to supply compressed air, causing the cylinder to extend. At this time, the hook claw 24 extends and abuts against the horizontal outer wall of the rod end bearing seat 50, firmly fixing the rod end bearing seat 50 onto the spindle assembly 20.

[0057] 4. The machine tool turns the tail 52 of the rod end bearing seat 50, and stops the machine after machining.

[0058] 5. Operate the machine tool again to discharge compressed air, causing the cylinder to retract. At this time, the hook claw 24 retracts again, and the rod end bearing seat 50 can be removed from the rod end bearing seat fixture.

[0059] 6. Replace with a new rod end bearing housing 50 and repeat the above steps.

[0060] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
