DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0049] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to the solutions required as the utility model described in the claims.

[0050] refer to Figure 1-7 The present embodiment provides a sealing ring installation machine, characterized in that it includes: a feeding device, a vertical plate 12, a conical column 3, a horizontal plate 6, a mounting plate 4 and a push claw 5. The base frame 1 is set on the ground. The feeding device is connected to the base frame 1, and a material trough is set on the feeding device. The workpiece 2 to be installed with the sealing ring can be placed in the material trough on the feeding device.

[0051] A lifting structure is connected to the base frame 1 , and the vertical plate 12 is connected to the lifting structure, so that the lifting structure can drive the vertical plate 12 to move up and down relative to the base frame 1 .

[0052] The conical column 3 is truncated cone-shaped, and its cross-sectional radius increases from top to bottom. A sleeve hole is set on the bottom surface of the conical column 3, and the top of the workpiece 2 can be inserted into the sleeve hole, so that after the bottom of the conical column 3 is sleeved on the top of the workpiece 2, the bottom edge of the conical column 3 is just located outside the installation position of the sealing ring on the workpiece 2. A frame is fixedly set on the vertical plate 12, and the conical column 3 is vertically connected to the frame, so that the conical column 3 is located above the material trough on the feeding device. When the workpiece 2 is placed in the material trough, the conical column 3 is located above the workpiece 2 and coaxial with the workpiece 2. The inner diameter of the sealing ring is larger than the top surface circle radius of the conical column 3 and smaller than the bottom surface circle radius of the conical column 3.

[0053] The horizontal plate 6 is fixedly connected to the vertical plate 12, a lifting device is provided on the horizontal plate 6, the mounting plate 4 is connected to the lifting device, so that the mounting plate 4 can be driven to move up and down by the lifting device, a push claw mounting structure is connected to the mounting plate 4, and the push claw 5 is connected to the push claw mounting structure. In this way, when the mounting plate 4 moves up and down, under the action of the push claw mounting structure, the push claw 5 can be pressed against the outer wall of the tapered column 3 and move up and down along the outer wall of the tapered column 3.

[0054] When it is necessary to put a sealing ring on the workpiece 2, put the sealing ring on the conical column 3, and use the lifting structure to drive the vertical plate 12 and the conical column 3 to rise. Place the workpiece 2 in the material trough on the feeding device, and the workpiece 2 is located below the conical column 3. Use the lifting structure to drive the vertical plate 12 and the conical column 3 to descend until the top of the workpiece 2 is inserted into the sleeve hole on the bottom surface of the conical column 3, and the bottom edge of the conical column 3 is located outside the sealing ring installation position on the workpiece 2. Use the lifting device to drive the mounting plate 4 to move downward, so that the push claw 5 rests on the outer wall of the conical column 3 and moves downward along the outer wall of the conical column 3. In this way, the push claw 5 pushes the sealing ring to move downward along the outer wall of the conical column 3. As the sealing ring moves downward, the sealing ring is stretched open by the conical column 3, and as the push claw 5 moves downward, the sealing ring is pushed out of the bottom surface of the conical column 3 and inserted into the installation position on the workpiece 2. After the installation is completed, the lifting structure is used to drive the vertical plate 12 and the conical column 3 to rise, and the workpiece 2 with the sealing ring is taken out from the material tank, and another workpiece 2 is put into the material tank, and the sealing ring is sleeved on the conical column 3, and the above steps are repeated to sleeve the sealing ring on another workpiece 2. In this way, instead of manually opening the sealing ring, it is more time-saving and labor-saving when installing the sealing ring.

[0055] As an optional embodiment, it also includes: a material column 7, a first push plate 8 and a second push plate 10. The horizontal plate 6 is provided with a through hole, and the top surface of the conical column 3 is fitted and connected with the bottom of the material column 7. The top of the material column 7 passes through the through hole on the horizontal plate 6 and is connected to the frame on the vertical plate 12. Specifically, a slot is provided on the frame, and after the top side wall of the material column 7 is embedded in the slot, the top of the material column 7 is pressed into the slot using a cover plate, and the cover plate is fixedly connected to the frame, so that the material column 7 is fixedly clamped in the slot.

[0056] The first cylinder 9 and the second cylinder 11 are arranged on the top surface of the cross plate 6. The first cylinder 9 and the second cylinder 11 are respectively located on both sides of the perforation. The cylinder body of the first cylinder 9 is fixedly connected to the top surface of the cross plate 6, and the first push plate 8 is connected to the piston rod of the first cylinder 9, so that the first cylinder 9 can drive the first push plate 8 to move close to and away from the axis of the perforation. The cylinder body of the second cylinder 11 is fixedly connected to the top surface of the cross plate 6, and the second push plate 10 is connected to the piston rod of the second cylinder 11, so that the second cylinder 11 can drive the second push plate 10 to move close to and away from the axis of the perforation. The first push plate 8 and the second push plate 10 are both provided with a tip at one end close to the perforation. In the vertical direction, the first push plate 8 is located above the second push plate 10, and the height difference between the first push plate 8 and the second push plate 10 is consistent with the thickness of a sealing ring.

[0057] Under normal conditions, the material column 7 passes through the perforation, and the second cylinder 11 drives the tip of the second push plate 10 to rest against the side wall of the material column 7. Multiple sealing rings are sleeved on the material column 7, and the multiple sealing rings are stacked up from the top surface of the second push plate 10 along the material column 7 in sequence under the action of gravity. The first cylinder 9 is used to drive the first push plate 8 to move closer to the material column 7 until the tip of the first push plate 8 separates the bottom sealing ring from the sealing ring adjacent to it. Then the second cylinder 11 is used to drive the second push plate 10 to move away from the material column 7. When the tip of the second push plate 10 leaves the bottom sealing ring, the bottom sealing ring falls along the material column 7 under the action of gravity and passes through the perforation and falls on the conical column 3.

[0058] After the bottom sealing ring falls, the second cylinder 11 is used to drive the second push plate 10 to reset. Then the first cylinder 9 is used to drive the first push plate 8 to move away from the material column 7. At this time, the bottom sealing ring on the material column 7 falls on the second push plate 10. By repeating the above steps, the sealing rings can be placed on the conical column 3 in turn, instead of manually placing the sealing rings on the conical column 3, which saves time and effort.

[0059] As an optional embodiment, the lifting structure includes: a screw 13, a lifting plate 15 and a hand wheel 16. A vertical plate 14 is fixedly arranged on the base frame 1, and a mounting block is connected to the top of the vertical plate 14. After a rotating hole is opened on the mounting block, the screw 13 is rotatably inserted into the rotating hole. The lifting plate 15 is connected to the vertical plate 12 so that the lifting plate 15 and the vertical plate 12 move synchronously. A threaded hole is set on the lifting plate 15, and the screw 13 is rotated and connected to the base frame 1 after passing through the threaded hole. In this way, due to the principle of screw transmission, the lifting plate 15 can be driven to move up and down by rotating the screw 13, thereby driving the vertical plate 12 to move up and down.

[0060] A vertical sliding rail and a sliding groove are respectively arranged on the side walls of the vertical plate 12 and the vertical plate 14 which are close to each other. The sliding rail is slidably arranged in the sliding groove to guide the vertical plate 12 to slide up and down along the vertical plate 14.

[0061] The hand wheel 16 is fixedly connected to the top of the screw rod 13, and the screw rod 13 can be rotated by rotating the hand wheel 16, which makes the operation more convenient.

[0062] In some embodiments, the lifting structure further includes: a third cylinder 17 and a guide sleeve 18. The cylinder body of the third cylinder 17 is fixedly arranged on the lifting plate 15, and the vertical plate 12 is connected to the piston rod of the third cylinder 17. In this way, after the lifting plate 15 is driven up and down by the screw rod, it is no longer adjusted, and the third cylinder 17 is used to further drive the vertical plate 12 to move up and down. In this way, instead of manually moving the vertical plate 12 up and down, it is more time-saving and labor-saving.

[0063] The guide sleeve 18 is connected to the lifting plate 15, and a guide post 19 is fixedly arranged upward on the base frame 1. The guide sleeve 18 is slidably sleeved on the guide post 19, and the guide sleeve 18 plays a guiding role in the up and down movement of the lifting plate 15 when sliding along the guide post 19.

[0064] As an optional embodiment, the lifting device includes: a fourth cylinder 20, a slider 21 and a slide rail 22. The cylinder body of the fourth cylinder 20 is fixedly arranged on the transverse plate 6, and the piston rod of the fourth cylinder 20 is connected to the mounting plate 4, so that the fourth cylinder 20 can drive the mounting plate 4 to move up and down.

[0065] The slider 21 is connected to the mounting plate 4, and a slide groove is vertically provided on the slider 21. The slide rail 22 is vertically fixedly arranged on the vertical plate 12. The slide groove on the slider 21 is slidably mounted on the slide rail 22, and when the slider 21 slides along the slide rail 22, it guides the mounting plate 4 to move up and down.

[0066] As an optional embodiment, the push claw installation structure includes: a sliding sleeve 23, a spring and a guide rod 24. The sliding sleeve 23 is fixedly connected to the bottom surface of the mounting plate 4, and the length direction of the sliding hole on the sliding sleeve 23 points to the axis of the perforation on the horizontal plate 6. The push claw 5 is inserted into the sliding hole on the sliding sleeve 23, so that the push claw 5 can slide along the sliding sleeve 23 and approach or move away from the axis of the perforation on the horizontal plate 6, and both ends of the push claw 5 pass through the sliding sleeve 23.

[0067] A first spring mounting point is provided on the outer wall of the sliding sleeve 23, and a second spring mounting point is provided on the inner end of the push claw 5. That is, the two ends of the spring are connected to the first spring mounting point and the second spring mounting point respectively, so that the inner end of the push claw 5 is connected to the outer wall of the sliding sleeve 23 through the spring. At this time, when the push claw 5 is pushed inward, the push claw 5 stretches the spring, and when the thrust is canceled or reduced, the spring rebounds and pulls the push claw 5 to slide outward.

[0068] The guide rod 24 is fixedly connected to the bottom surface of the mounting plate 4, and is located at the outer periphery of the outer end of the push claw 5 and in the length direction of the push claw 5, and the outer end of the push claw 5 abuts against the outer wall of the guide rod 24. A first inclined surface 28 and a second inclined surface 29 are sequentially arranged from top to bottom on one side of the guide rod 24 close to the tapered column 3. The first inclined surface 28 is inclined inward from top to bottom, and the second inclined surface 29 is inclined outward from top to bottom.

[0069] When the fourth cylinder 20 drives the mounting plate 4 to move downward, the outer end of the push claw 5 slides downward from the top of the first inclined surface 28 along the first inclined surface 28 until it slides to the bottom of the first inclined surface 28, and the inner end of the push claw 5 moves close to the material column 7 and abuts against the outer wall of the bottom end of the material column 7. Thereafter, the outer end of the push claw 5 slides downward from the top of the second inclined surface 29 along the second inclined surface 29, and the inner end of the push claw 5 begins to abut against the outer wall of the tapered column 3. As the mounting plate 4 moves downward, under the rebound effect of the spring, the outer end of the push claw 5 keeps abutting against the bottom of the second inclined surface 29, while the inner end of the push claw 5 keeps abutting against the outer wall of the tapered column 3. After the mounting plate 4 moves downward for a certain distance, it pushes the sealing ring downward until the sealing ring is pushed out of the bottom surface of the tapered column 3 and inserted into the mounting position on the workpiece 2.

[0070] In some embodiments, five sliding sleeves 23 are arranged along the circumference of the perforations on the transverse plate 6, and each sliding sleeve 23 is provided with a push claw 5. The five push claws 5 work simultaneously, and the pushing effect on the sealing ring is better.

[0071] As an optional embodiment, the loading device includes: a material plate 25, a fifth cylinder 26 and a support block 27. A material trough is provided on the material plate 25, and the workpiece 2 can be placed in the material trough. The cylinder body of the fifth cylinder 26 is fixedly provided on the base frame 1, and the piston rod of the fifth cylinder 26 is connected to the material plate 25, so that the fifth cylinder 26 can drive the material plate 25 to move. The support block 27 is fixedly connected to the base frame 1, a slide groove is provided on the top of the support block 27, and a material plate slide rail is provided at the bottom of the material plate 25, and the material plate slide rail is slidably inserted in the material plate slide groove, and the material plate slide rail slides along the material plate slide groove to provide a guide for the movement of the material plate 25.

[0072] When loading, the workpiece 2 is placed in the trough on the material plate 25, and the fifth air cylinder 26 is used to drive the material plate 25 to move until the trough is located below the conical column 3. After the sealing ring is installed on the workpiece 2, the fifth air cylinder 26 is used to drive the material plate 25 back to the loading position, the installed workpiece 2 is taken out of the trough, and the next workpiece 2 to be installed is placed in the trough.
