Description

Technical Field

[0001] The utility model relates to the technical field of lathe clamps, in particular to a lathe clamp for a rocker arm part. Background Art

[0002] A rocker arm is a device used to produce rotational or swinging motion in a mechanical system. One end of the device is fixed, and the other end can swing along an axis or fulcrum. Rocker arms are used in mechanical equipment, tools, vehicles, etc. in different fields to achieve specific functions. When using a lathe to process rocker arm parts, a fixture is required to clamp and fix the rocker arm parts.

[0003] In the prior art, the lathe fixture is mainly composed of a chuck, a plurality of jaws and a clamping block. The jaws and the clamping block can clamp and fix the workpiece to be processed. In order to facilitate the maintenance of the jaws, an oil filling valve will be installed on the jaws to facilitate the filling of lubricating oil into the jaws for maintenance.

[0004] The above-mentioned and prior art technologies have the following defects: when processing lubricating oil into the oil filling valve, the staff needs to align the oil outlet of the oil gun with the oil filling valve. Since the valve port of the oil filling valve is small, it is difficult for the staff to align the oil gun with the oil filling valve for a long time, thereby increasing the difficulty of maintenance.

[0005] Therefore, a rocker arm part lathe fixture is proposed. Utility Model Content

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rocker arm part lathe fixture, including a chuck and a rocker arm part, the inner wall of the chuck is installed with a first claw, the inner wall of the chuck is installed with two second claws, the first claw and the second claw are fixedly connected with an oil filling valve, the surface of the first claw is fixedly connected with a first clamping block, the surface of the chuck is fixedly connected with a second clamping block, the surface of the chuck is fixedly connected with a third clamping block, the first clamping block, the second clamping block and the third clamping block are all engaged with the rocker arm part, the arc surface of the chuck is provided with an auxiliary structure, the auxiliary structure includes three fixed plates, the fixed plate is fixedly connected to the chuck, the surface of the fixed plate is slidably connected with a swivel, the surface of the swivel is fixedly connected with a rectangular frame, the inner wall of the rectangular frame is slidably connected with a connecting plate, and the surface of the connecting plate is fixedly connected with a guide frame.

[0008] The effect achieved by the above-mentioned components is: by setting up the auxiliary structure, when the guide frame is against the surface of the oil filling valve, the muzzle of the oil gun will be aligned with the oil filling valve, and lubricating oil can be added to the oil filling valve at this time. The guide frame reduces the difficulty of aligning the oil gun and the oil filling valve, thereby facilitating the oil filling operation and reducing the difficulty of maintenance of the fixture.

[0009] Preferably, a leaf spring is fixedly connected to the surface of the connecting plate, and one end of the leaf spring is fixedly connected to the rectangular frame.

[0010] The effect achieved by the above components is that when the leaf spring contracts, the connecting plate drives the guide frame to move so that the moving frame is out of contact with the oil filling valve, thereby preventing the oil filling valve from interfering with the movement of the guide frame.

[0011] Preferably, an insertion rod is slidably penetrated in the rotating ring, a slot is provided on the surface of the fixing plate, and the size of the insertion rod is matched with the size of the slot.

[0012] The effect achieved by the above components is that the slot limits the position of the plug rod, thereby limiting the position of the swivel, so that the guide frame is aligned with the oil filling valve.

[0013] Preferably, the arc surface of the insertion rod is sleeved with a spring, and two ends of the spring are fixedly connected to the insertion rod and the swivel respectively.

[0014] The effect achieved by the above components is that when the spring contracts, the insertion rod will automatically be inserted into the slot with the help of the tension of the spring.

[0015] Preferably, the swivel is fixedly connected with an L-shaped plate relative to the insertion rod.

[0016] The effect achieved by the above components is that when the insertion rod contacts the L-shaped plate, the L-shaped plate limits the moving distance of the insertion rod, thereby preventing the insertion rod from being out of contact with the rotating ring.

[0017] Preferably, an inclined plate is fixedly connected to the surface of the fixing plate.

[0018] The effect achieved by the above components is that when the insertion rod contacts the inclined plate, the inclined plate will squeeze the insertion rod, and the insertion rod will slide along the rotating ring and stretch the spring.

[0019] Preferably, two counterweights are fixedly connected to the arc surface of the swivel.

[0020] The effect achieved by the above components is that the two counterweights can balance the weight of other components on the swivel, thereby ensuring that the chuck can rotate normally.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] In the utility model, by providing an auxiliary structure, when the guide frame is against the surface of the oil filling valve, the muzzle of the oil gun will be aligned with the oil filling valve, and lubricating oil can be added to the oil filling valve at this time. The guide frame reduces the difficulty of aligning the oil gun and the oil filling valve, thereby facilitating the oil filling operation and reducing the difficulty of maintenance of the clamp.

[0033] like Figure 2-Figure 6 As shown, the arc surface of the plug rod 507 is sleeved with a spring 509, and the two ends of the spring 509 are fixedly connected to the plug rod 507 and the rotating ring 502 respectively. When the spring 509 contracts, the plug rod 507 will automatically insert into the slot 508 with the help of the tension of the spring 509. The rotating ring 502 is fixedly connected with an L-shaped plate 510 relative to the position of the plug rod 507. When the plug rod 507 contacts the L-shaped plate 510, the L-shaped plate 510 reaches the limit of the movement distance of the plug rod 507, thereby preventing the plug rod 507 from 507 has the effect of disengaging contact with the rotating ring 502, and the surface of the fixed plate 501 is fixedly connected with an inclined plate 511. When the insertion rod 507 contacts the inclined plate 511, the inclined plate 511 will squeeze the insertion rod 507, and the insertion rod 507 will slide along the rotating ring 502 and stretch the spring 509. The arc surface of the rotating ring 502 is fixedly connected with two counterweights 512. The two counterweights 512 can balance the weight of other components on the rotating ring 502, thereby ensuring that the chuck 1 can rotate normally.

[0034] The overall working principle is that the rocker arm 9 can be clamped and fixed by means of the cooperation of the first clamping claw 2, the second clamping claw 3, the first clamping block 6, the second clamping block 7 and the third clamping block 8, so as to facilitate lathe processing of the rocker arm 9. When oil needs to be injected into the oil injection valve 4, the rotating ring 502 is moved along the surface of the fixed plate 501, and the movement of the rotating ring 502 will drive the insertion rod 507 to move. When the insertion rod 507 contacts the inclined plate 511, the inclined plate 511 will squeeze the insertion rod 507, and the insertion rod 507 will slide along the rotating ring 502 and stretch the spring 509, so that The spring 509 is in a stretched state. When the rod 507 is aligned with the slot 508, the spring 509 begins to contract. The rod 507 is inserted into the slot 508 with the help of the tension of the spring 509. The slot 508 reaches the position of limiting the rod 507, thereby limiting the position of the swivel 502, so that the guide frame 505 is aligned with the oil filling valve 4. Then, the muzzle of the oil gun is inserted into the guide frame 505. The muzzle of the oil gun slides along the inner wall of the guide frame 505 and squeezes the guide frame 505. The guide frame 505 drives the connecting plate 504 to move along the rectangular frame 50 3 slides on the inner wall and stretches the leaf spring 506. When the guide frame 505 is against the surface of the oil filling valve 4, the muzzle of the oil gun will be aligned with the oil filling valve 4. At this time, lubricating oil can be added to the oil filling valve 4. The guide frame 505 reduces the difficulty of aligning the oil gun and the oil filling valve 4, thereby facilitating the oil filling operation and reducing the difficulty of maintaining the fixture. After the oil filling is completed, the oil gun is removed. At this time, the leaf spring 506 begins to shrink, and the connecting plate 504 drives the guide frame 505 to move so that the movable frame is out of contact with the oil filling valve 4, thereby preventing the oil filling valve 4 from hindering the movement. When the guide frame 505 is in the state of being guided, when it is necessary to fill oil to other oil filling valves 4, the plug rod 507 is pulled to make the plug rod 507 disengage from the slot 508, and then the swivel 502 can continue to be rotated. When the plug rod 507 contacts with the L-shaped plate 510, the L-shaped plate 510 limits the movement distance of the plug rod 507, thereby preventing the plug rod 507 from disengaging from the swivel 502. When the chuck 1 rotates, the two counterweights 512 can balance the weight of other components on the swivel 502, thereby ensuring that the chuck 1 can rotate normally.
