Description

Technical Field

[0001] This utility model belongs to the field of sealing ring assembly technology, specifically relating to a sealing ring clamp assembly device. Background Technology

[0002] A sealing ring is a component used for sealing. Sealing rings typically need to be fitted into an annular groove. Currently, the methods for fitting sealing rings vary across industries. Some use manual fitting, some use semi-automatic devices, some use simple tooling sticks for assistance, and a few use automatic fitting machines. Manual fitting and using simple devices undoubtedly require a large amount of manpower and are inefficient. Semi-automatic devices can reduce the labor intensity of manual fitting to a small extent, but they require more intermediate fixtures and still require a large amount of manpower, resulting in relatively low efficiency, which needs further improvement. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sealing ring clamp assembly device.

[0004] The present invention adopts the following technical solution:

[0005] A sealing ring clamp assembly device includes an assembly base, a ring support mechanism, and a material pushing mechanism.

[0006] The support ring mechanism is set on the mounting base and can expand outward to clamp the sealing ring. It includes multiple support ring clamps circumferentially distributed at the first end of the mounting base and a reset component set on the mounting base that can drive the multiple support ring clamps to reset. The support ring clamps can move back and forth along the radial direction of the mounting base.

[0007] The pushing mechanism, mounted on the assembly base, can drive multiple support ring grippers to move outward to expand and clamp the sealing ring. It includes a movable rod mounted in the assembly base that can move along the direction close to the support ring mechanism, a conical pusher head arranged at the first end of the movable rod close to the support ring mechanism, a movable component connected to and driving the movable rod, and a pushing component arranged at the second end of the movable rod to push the sealing ring outward. The outer diameter of the conical pusher head gradually decreases along the direction close to the support ring grippers. The opposing surfaces of the support ring grippers and the conical pusher head form a guide inclined surface adapted to the outer circumferential surface of the conical pusher head. The movement of the movable rod close to the support ring mechanism causes the outer circumferential surface of the conical pusher head to gradually contact and abut against the guide inclined surface, thereby driving the support ring grippers to move outward to expand and clamp the sealing ring. The pushing component can move along the direction close to the support ring grippers to push the sealing rings clamped on the multiple support ring grippers outward.

[0008] Furthermore, the pusher includes a pusher ring arranged around the moving rod and multiple pusher rods circumferentially distributed on the pusher ring and arranged around the moving rod. The pusher rods can move in the direction close to the support ring claws to push the sealing rings clamped on the multiple support ring claws outward.

[0009] Furthermore, the end face of the assembly base is provided with multiple moving slots for moving multiple support ring grippers and multiple pushing holes for passing through multiple pushing rods, with the pushing holes located between two adjacent moving slots.

[0010] Furthermore, the pushing mechanism also includes a pushing plate arranged at the second end of the moving rod away from the support ring mechanism. The moving part is connected to the pushing plate to drive the moving rod and the pushing part to move in the assembly seat respectively. The moving part can drive the moving rod to move close to the support ring claw until the conical push head and the guide inclined surface are disengaged. At this time, the pushing plate moves to contact the pushing ring.

[0011] Furthermore, the assembly base has a moving cavity for the moving rod and the pusher to move. The pusher mechanism also includes a reset spring disposed in the moving cavity to drive the pusher to reset. The reset spring is sleeved on the moving rod, with its first end connected to the pusher ring and its second end connected to the inner wall of the moving cavity to drive the pusher to reset.

[0012] Furthermore, the reset assembly includes a limiting sleeve disposed at the first end of the mounting base surrounding multiple support ring claws and multiple limiting springs disposed between the multiple support ring claws and the limiting sleeve. The first end of the limiting spring is connected to the inner wall of the limiting sleeve, and the second end is connected to the opposite support ring claw.

[0013] Furthermore, the opposing surfaces of the support ring gripper and the inner wall of the limiting sleeve form an inwardly extending connecting hole, and the second end of the limiting spring extends into the connecting hole and connects with the inner wall of the connecting hole.

[0014] Furthermore, the support ring gripper includes a clamping block that can move back and forth radially along the mounting base and a clamping part disposed on the clamping block for clamping the sealing ring. The sealing ring is expanded and clamped on the outer periphery of multiple clamping parts. A guide inclined surface is disposed on the opposite surface of the clamping block and the moving rod. An expansion area for the moving rod to move is formed between the inner sides of the multiple clamping blocks.

[0015] Furthermore, the moving part includes a cylinder seat located at the second end of the mounting base away from the support ring mechanism and a pusher cylinder connected to the moving rod on the cylinder seat. The cylinder seat is provided with a clearance hole for the piston rod of the pusher cylinder to pass through.

[0016] Furthermore, it also includes a pressure cap disposed at the first end of the mounting base, the shape of which is adapted to the end face of the first end of the mounting base.

[0017] As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are as follows: The present application defines the structure of the pushing mechanism, sets a movable moving rod to cooperate with the conical push head, and sets a guide inclined surface on the support ring gripper to cooperate with the outer peripheral surface of the conical push head. Through the cooperation of the conical push head and the guide inclined surface, multiple support ring grippers can move outward synchronously to expand and grip the sealing ring. At the same time, a pushing component that can move with the moving rod is further set to push the sealing ring gripped on the support ring gripper outward and fit it on the product part. The operation method is simple, and the expansion, gripping and pushing assembly process of the sealing ring can be realized by itself. There is no need for intermediate fixtures to expand the sealing ring, reducing intermediate processes and parts cooperation. Moreover, the pushing component is hidden in the assembly seat, does not occupy the size of the device, and will not damage the sealing ring when pushing it outward. Attached Figure Description

[0027] The present invention will be further described below through specific embodiments.

[0028] Reference Figures 1 to 3 As shown, a sealing ring clamp assembly device includes an assembly base 1, a ring support mechanism 2, a material pushing mechanism 3, and a pressure cap 4.

[0029] The support ring mechanism 2, mounted on the mounting base 1, can expand outward to clamp the sealing ring 5. It includes multiple support ring grippers 21 circumferentially distributed at the first end of the mounting base 1 and a reset assembly 22 mounted on the mounting base 1 that can drive the multiple support ring grippers 21 to reset. The support ring grippers 21 can move back and forth radially along the mounting base 1 to expand outward to clamp the sealing ring 5 or retract inward to reset. Specifically, refer to... Figure 5 As shown, the support ring clamp 21 includes a clamping block 211 that can move back and forth radially along the mounting base 1 and a clamping portion 212 disposed on the clamping block 211 for clamping the sealing ring 5. The outer diameter of the clamping portion 212 is smaller than the outer diameter of the clamping block 211, and the sealing ring 5 expands and is clamped around the outer periphery of the plurality of clamping portions 212; correspondingly, referring to Figure 4 As shown, the end face of the mounting base 1 is formed with a plurality of moving grooves 11 for the plurality of clamping blocks 211 to move back and forth, and the moving grooves 11 extend radially outward from the center of the end face of the mounting base 1; further, an expansion region 24 is formed between the inner sides of the plurality of clamping blocks 211.

[0030] The reset assembly 22 includes a limiting sleeve 221 disposed around a plurality of clamping blocks 211 at the first end of the mounting base 1, and limiting springs 222 respectively disposed between the plurality of clamping blocks 211 and the limiting sleeve 221. The first end of the limiting spring 222 is connected to the inner wall of the limiting sleeve 221, and the second end is connected to the opposite clamping block 211. When the support ring clamp 21 moves outward and expands, it compresses the limiting spring 222, putting the limiting spring 222 into a compressed state. When the sealing ring 5 disengages from the support ring clamp... After the claw 21 is released, the limiting spring 222 is released and reset, causing the relative support ring claw 21 to move inward and retract to reset. Specifically, the opposing surfaces of the clamping block 211 and the inner wall of the limiting sleeve 221 form an inwardly extending connecting hole 213. The second end of the limiting spring 222 extends into the connecting hole 213 and connects with the inner wall of the connecting hole 213. The setting of the connecting hole 213 can guide the compression and reset of the limiting spring 222. With the setting of the moving groove 11, the support ring claw 21 moves back and forth stably.

[0031] The pushing mechanism 3, mounted on the assembly base 1, can drive multiple support ring grippers 21 to move outward to expand and grip the sealing ring 5. It includes a movable rod 31 movable in the assembly base 1 along the direction close to the support ring grippers 21; a conical pusher 32 positioned at the first end of the movable rod 31 near the support ring grippers 21; a movable component 33 connecting to and driving the movable rod 31; a pushing component 34 in the assembly base 1 that pushes the sealing ring 5 outward; and a component positioned at the second end of the movable rod 31 away from the support ring grippers 21. The assembly base 1 includes a pusher plate 35 arranged with a ring gripper 21 and a return spring 36 that drives the pusher 34 to reset. The assembly base 1 has a moving cavity 12 for moving the moving rod 31 and the pusher 34, and the moving cavity 12 communicates with the expansion region 24 via a transition hole 13. The moving rod 31 extends into the expansion region 24 via the transition hole 13. Specifically, the outer diameter of the conical pusher 32 gradually decreases along the direction close to the ring gripper 21. The clamping block 211 and the conical pusher 32... The opposite surface of the cone pusher 32 has a guide inclined surface 23 that is adapted to the outer peripheral surface of the cone pusher 32, and the guide inclined surface 23 is located on the side of the clamping block 211 near the moving cavity 12. When the moving rod 31 moves in the direction close to the support ring clamp 21, the cone pusher 32 extends into the expansion area 24, so that its outer peripheral surface gradually contacts and abuts the guide inclined surface 23, thereby driving the support ring clamp 21 to move outward to expand and clamp the sealing ring 5. The moving rod 31 continues to move, and the outer peripheral surface of the cone pusher 32 disengages from the guide inclined surface 23. At this time, the outer peripheral surface of the moving rod 31 contacts the inner side of the clamping block 211, and the support ring clamp 21 reaches the maximum outward expansion degree. Furthermore, the fit between the outer peripheral surface of the cone pusher 32 and the guide inclined surface 23 can be made according to the assembly requirements of sealing rings 5 ​​of different sizes, and the expansion size of the sealing ring 5 can be strictly controlled to allow the use of sealing rings 5 ​​of different models, and can simultaneously adapt to the assembly of sealing rings 5 ​​of a certain size using this device.

[0032] The movable component 33 includes a cylinder seat 331 disposed at the second end of the assembly base 1 away from the support ring clamp 21, and a pusher cylinder 332 disposed on the cylinder seat 331 and connected to the pusher plate 35. The cylinder seat 331 is provided with a clearance hole 333 for the piston rod of the pusher cylinder 332 to pass through. Specifically, the pusher cylinder 332 is connected to a five-position three-way solenoid valve to realize three holding positions of the pusher cylinder 332, so as to realize the middle position expansion clamping of the sealing ring 5, the final position push assembly, and the original position reset standby. Furthermore, the movable component 33 can also be a motor to realize the above-mentioned three holding positions of the pusher cylinder 332.

[0033] The pusher 34 includes a pusher ring 341 surrounding the moving rod 31 and a plurality of pusher rods 342 circumferentially distributed on the pusher ring 341 surrounding the moving rod 31. The pusher rods 342 can move along the direction close to the support ring claw 21 under the action of the moving rod 31 to push the sealing rings 5 ​​on the plurality of support ring claws 21 outward. The end face of the first end of the mounting base 1 is provided with a plurality of pusher holes 14 through which the plurality of pusher rods 342 pass, and the pusher holes 14 are located between two adjacent moving grooves 11. The first end of the pusher rod 342 is connected to the pusher ring 341, and the second end extends into the corresponding pusher hole 14. When the moving rod 31 moves until the outer peripheral surface of its conical pusher 32 disengages from the guide inclined surface 23, the outer peripheral surface of the moving rod 31 contacts the inner side of the clamping block 211, and the pusher plate 35 moves to contact the pusher ring 341. The moving rod 31 continues to move, and the pusher rod 342 moves outward under the action of the pusher plate 35, which pushes the sealing ring 5 that has been opened on the support ring clamp 21 outward and puts it on the product part. Specifically, the contact surface between the pusher rod 342 and the sealing ring 5 is a plane, so that the pusher rod 342 pushes the sealing ring 5 with its front side without damaging the sealing ring 5.

[0034] The reset spring 36 is sleeved on the moving rod 31. The first end is connected to the pusher ring 341, and the second end is connected to the inner wall of the moving cavity 12 to drive the pusher 34 to reset. When the moving rod 31 drives the pusher ring 341 to move in the direction close to the support ring clamp 21, the pusher plate 35 will move with the moving rod 31 to squeeze the reset spring 36. When the pusher rod 342 pushes the sealing ring 5 outward, the moving part 33 drives the moving rod 31 to reset. The reset spring 36 is released and reset without the limit of the pusher plate 35, thereby driving the pusher 34 to move and reset in the direction close to the moving part 33.

[0035] A pressure cap 4 is disposed at the first end of the mounting base 1, and its shape is adapted to the end face of the first end of the mounting base 1, wherein the clamping part 212 extends out of the pressure cap 4.

[0036] Reference Figures 6 to 8As shown, during assembly, the sealing ring 5 rests against the pressure cap 4, located on the outer periphery of multiple clamping parts 212. The pusher cylinder 332 controls the moving rod 31 to move outward closer to the sealing ring 5. The outer peripheral surface of the conical pusher head 32 gradually comes into contact with the guide inclined surface 23 on the inner side of the support ring clamp 21, causing the multiple support ring clamps 21 to move outward and expand. When the multiple support ring clamps 21 move outward to their maximum extent to expand and clamp the sealing ring 5, the outer peripheral surface of the conical pusher head 32 just disengages from the guide inclined surface 23, and the moving rod 31 just contacts the inner side of the support ring clamp 21. At this time, the pusher... Plate 35 contacts push ring 341; then push cylinder 332 controls moving rod 31 to continue moving outward, push plate 35 drives push rod 342 to move outward to push sealing ring 5 outward, so that sealing ring 5 is disengaged from multiple support ring clamps 21 and sleeved on product parts to complete the assembly of sealing ring 5; after sealing ring 5 is assembled, push cylinder 332 drives moving rod 31 to move in the opposite direction to reset, support ring clamps 21 and push part 34 move in the opposite direction to reset to the initial position under the action of limit spring 222 and reset spring 36 respectively, completing one assembly process.

[0037] This application defines the structure of the pusher mechanism 3, sets a movable moving rod 31 that cooperates with the conical pusher head 32, and sets a guide inclined surface 23 on the support ring gripper 21 that cooperates with the outer peripheral surface of the conical pusher head 32. Through the cooperation of the conical pusher head 32 and the guide inclined surface 23, multiple support ring grippers 21 can move outward synchronously to expand and grip the sealing ring 5. At the same time, a pusher component 34 that can move with the moving rod 31 is further set to push the sealing ring 5 gripped on the support ring gripper 21 outward and fit it onto the product part. The operation is simple and can realize the expansion, gripping and pusher assembly process of the sealing ring 5 by itself. There is no need for intermediate fixtures to expand the sealing ring 5, reducing intermediate processes and parts cooperation. Moreover, the pusher component 34 is hidden in the assembly base 1, does not occupy the size of the device, and will not damage the sealing ring 5 when pushing it outward.

[0038] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
