Description

Technical Field

[0001] This utility model relates to the field of metal material processing technology, and in particular to a device for gripping and loading spring clips. Background Technology

[0002] like Figure 1 As shown, a shaft retaining ring, also known as a shaft elastic retaining ring or snap ring, is a type of elastic fastener installed on a grooved shaft. It achieves axial positioning through the cooperation of elasticity and groove. Its inner diameter is slightly smaller than the shaft diameter, and it needs to be expanded using snap ring pliers before being inserted into the shaft groove during installation. It is suitable for shaft components in hydraulic systems, pneumatic systems, and various mechanical equipment.

[0003] A retaining circlip needs to be installed in the shaft groove. Accurate positioning is crucial during installation to prevent misalignment. Currently, gripping equipment frequently experiences inaccurate placement of the retaining circlip within the shaft groove, requiring subsequent inspection and adjustment by workers, thus reducing installation efficiency.

[0043] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0044] Example

[0045] like Figure 2 As shown, a device for gripping and loading a snap ring according to this embodiment includes a worktable 1, a mounting platform 2, a conveying mechanism 3, and a gripping mechanism 4.

[0046] In this embodiment, the bottom of the workbench 1 is provided with casters 5 to facilitate moving the workbench 1 to a designated position. The bottom corner of the workbench 1 is provided with pads 6, which are threadedly connected to the bottom of the workbench 1. When the workbench 1 is moved to the designated position, the working surface of the workbench 1 can be kept horizontal by adjusting the height of the pads 6.

[0047] The mounting platform 2 is disposed on the workbench 1, and the mounting platform 2 has a placement slot 7 for placing shaft parts in the motor to be loaded with snap rings.

[0048] like Figure 3 As shown, the conveying mechanism 3 includes a limiting channel 8 and a pushing mechanism 9; the limiting channel 8 is disposed on the worktable 1, and the cross-section of the limiting channel 8 is adapted to the snap ring to be conveyed, so that the two prongs of the snap ring are vertically downward for conveying; the pushing mechanism 9 includes a support base 10, an L-shaped pushing block 11, and a placement platform 12; the inlet of the support base 10 is directly opposite the outlet of the limiting channel 8; as shown Figure 4 As shown, the support base 10 is provided with a sliding groove 13, which is horizontally arranged and perpendicular to the limiting channel 8; the L-shaped pusher block 11 is slidably arranged on the sliding groove 13, and the end of the L-shaped pusher block 11 is always located outside the sliding groove 13; as shown Figure 5 As shown, the L-shaped pusher block 11 has a limiting groove 14 at its front end facing the limiting channel 8. The thickness of the limiting groove 14 is greater than the thickness of one retaining spring and less than the thickness of two retaining springs. The worktable 1 is equipped with a first cylinder 15 for driving the L-shaped pusher block 11 to move on the slide groove 13.

[0049] The placement platform 12 is horizontally rotatably mounted on one side of the front end of the support base 10, such as... Figure 6 As shown, the top of the placement platform 12 is provided with a contour groove 16, and the contour groove 16 has a notch 17, which is directly opposite the L-shaped pusher block 11.

[0050] When the first cylinder 15 drives the L-shaped pusher block 11 to move backward to the end, the limiting groove 14 is exactly aligned with the outlet of the limiting channel 8; when the first cylinder 15 drives the L-shaped pusher block 11 to move forward, and the end of the L-shaped pusher block 11 is blocked by the support seat 10, the notch 17 on the contour groove 16 is aligned with the limiting groove 14.

[0051] In this embodiment, the top of the support base 10 is covered with a protective cover 18, which serves a protective function.

[0052] In this embodiment, the top of the support base is horizontally provided with an air blowing pipe 19, which aligns with the contour groove 16 on the placement platform 12; the height of the limiting groove 14 is less than the height of the retaining spring to be conveyed. With this configuration, when the first cylinder 15 pushes the L-shaped pusher block 11 forward until the limiting groove 14 is directly aligned with the contour groove 14 on the placement platform 12, the external air source blows the retaining spring through the air blowing pipe 19, causing it to fall into the contour groove 16.

[0053] like Figure 7 As shown, the gripping mechanism 4 includes a bracket 20 and a gripping component 21; the bracket 20 is disposed on the worktable 1; a first slide rail 22 is horizontally disposed on the bracket 20; a horizontal moving seat 23 is slidably disposed on the first slide rail 22; a second cylinder 24 is disposed on the bracket 20 for driving the horizontal moving seat 23 to move on the first slide rail 22; a third cylinder 25 is disposed on the horizontal moving seat 23, and the piston rod of the third cylinder 25 is disposed vertically downward; the gripping component 21 is disposed at the end of the piston rod of the third cylinder 25 for gripping the snap ring on the placement table 12 and transferring it to the mounting table 2 for sleeve on the shaft part.

[0054] In this embodiment, as Figure 7 As shown, the gripper 21 includes a vertical moving seat 26 and a snap ring clamping mechanism 27. The vertical moving seat 26 is located at the end of the piston rod of the third cylinder 25. The snap ring clamping mechanism 27 is located on the vertical moving seat 26 and corresponds to the contour groove 14 on the placement platform 12. After the snap ring is supported on the placement platform 12, it is rotated 90 degrees clockwise so that the two antennae on the snap ring are directly below the working part on the snap ring clamping mechanism 27. The second cylinder 24 and the third cylinder 25 work together to activate the snap ring clamping mechanism 27 and clamp the snap ring. Then the third cylinder 25 drives the gripper 21 to lift upward, and the second cylinder 24 drives the horizontal moving seat 23 to move directly above the mounting platform 2. The gripper 21 is activated again so that it is accurately and without deviation installed into the corresponding shaft groove on the shaft part. Then the gripper 21 releases the snap ring and is removed to complete the assembly.

[0055] In this embodiment, as Figure 7 As shown, the bracket 20 is also vertically provided with a second slide rail 28, and the vertical moving seat 26 is slidably disposed on the second slide rail 28, which effectively ensures the accuracy of the movement direction of the vertical moving seat 26 and avoids it from shaking, which would affect the gripping operation.

[0056] like Figure 8As shown, when the above-mentioned device is working, the external conveying device sequentially passes the retaining springs 29 through the limiting channel 8. Since the cross-section of the limiting channel 8 is adapted to the retaining springs 29 to be conveyed, the two tentacles of the retaining springs 29 are conveyed vertically downwards. Then, it passes through the inlet of the support base 10 and enters the limiting groove 14 on the L-shaped pusher block 11. Since the thickness of the limiting groove 14 is greater than the thickness of one retaining spring 29 but less than the thickness of two retaining springs 29, when the first cylinder 15 drives the L-shaped pusher block 11 to move on the slide 13, there is only one retaining spring 29 in the limiting groove 14. When the first cylinder 15 pushes the L-shaped pusher block 11 forward until the limiting groove 14 is directly opposite the placement platform 12... The external air source blows the retaining ring 29 into the contour groove 16 through the air pipe 19. After the retaining ring 29 is supported on the placement platform 12, it is rotated 90 degrees clockwise so that the two tentacles on the retaining ring 29 are directly below the working part of the retaining ring clamp mechanism 27. The second cylinder 24 and the third cylinder 25 work together to activate the retaining ring clamp mechanism 27 and clamp the retaining ring 29. Then the third cylinder 25 drives the gripper 21 to lift upward, and the second cylinder 24 drives the horizontal moving seat 23 to move directly above the mounting platform 2. The gripping mechanism is activated again so that it is accurately and without deviation installed into the corresponding shaft groove on the shaft part 30. Then the gripper 21 releases the retaining ring and removes it to complete the assembly.
