Description

Technical Field

[0001] The present application relates to the field of vehicle component processing, and in particular to a retaining spring assembly mechanism. Background Art

[0002] A retaining ring, also known as a retaining ring or a snap ring, is a type of fastener that is installed in the shaft groove or hole groove of a machine or equipment to prevent the axial movement of parts on the shaft or hole.

[0003] In the prior art, a circlip is generally installed on a car ball head to strengthen the connection, and a circlip groove for installing the circlip is generally provided on the ball head. The outer diameter of the ball head is generally larger than the inner diameter of the circlip. The circlip is elastic, and during installation, the circlip needs to be stretched and sleeved on the ball head with the help of tools such as circlip pliers, and then the circlip is pushed so that the circlip slides on the ball head into the circlip groove, and then the circlip pliers are removed, and the circlip recovers its deformation and is clamped in the circlip groove.

[0004] During the installation process, when workers use tools to open the retaining spring, it is difficult to control the force, and the tools are easy to slip, causing the tools to scratch the workers. Utility Model Content

[0005] In order to improve the convenience of installing the retaining spring and reduce the possibility of workers being scratched, the present application provides a retaining spring assembly mechanism.

[0006] A retaining spring assembly mechanism includes a base, a positioning block for connecting a ball head is provided on the base, at least two fixed blocks are symmetrically arranged on the base relative to the positioning block, the fixed blocks are slidably connected to the base, and a moving mechanism for the fixed blocks to approach and move away from the positioning block is provided on the base, a clamping plate for opening the retaining spring is provided on the side of the fixed block close to the positioning block, the clamping plate is used to abut against the ball head, and a pressing mechanism for installing the retaining spring on the retaining spring groove is provided on the fixed block.

[0007] By adopting the above technical solution, the fixed block drives the clamping plate to move through the moving mechanism. When the clamping plates are close to each other, the retaining spring is installed to the periphery of each clamping plate, and then the clamping plates are driven away by the moving mechanism so that the retaining spring is stretched open by the clamping plates, and then the ball head is connected to the positioning block. At this time, each clamping plate clamps the fixed ball head, and then the retaining spring is pressed by the pressing mechanism to move the retaining spring from the clamping plate to the retaining spring of the ball head, and restore the deformation to be clamped in the retaining spring groove of the ball head to complete the installation of the retaining spring, thereby reducing the possibility of workers being scratched and improving the convenience of retaining spring installation.

[0008] Preferably, the base is provided with a sliding groove on the outer periphery of the positioning block for the sliding of the fixing block.

[0009] By adopting the above technical solution, the fixed block is pressed against the base in the sliding groove, thereby reducing the situation where the fixed block is separated from the base, thereby improving the stability of the installation of the fixed block. The symmetrically arranged sliding grooves are symmetrically arranged about the positioning block, thereby improving the clamping effect of the clamping plate on the ball head.

[0010] Preferably, the symmetrically arranged fixing blocks are evenly distributed along the circumferential direction of the positioning block.

[0011] By adopting the above technical solution, multiple fixing blocks are provided, and multiple clamping plates are correspondingly provided for the multiple fixing blocks. Compared with two clamping plates, the retaining spring is fully supported by the multiple clamping plates, thereby improving the convenience of installing the retaining spring.

[0012] Preferably, a side of the fixing block close to the positioning block is symmetrically provided with a retreat groove for merging adjacent fixing blocks, and a side of the pressing mechanism close to the positioning block is symmetrically provided with a retreat cavity for merging adjacent pressing mechanisms.

[0013] By adopting the above technical solution, when the fixing blocks are close to each other, the adjacent fixing blocks are fitted together through the retreat grooves, and the adjacent pressure blocks are fitted together through the retreat cavities, so that the periphery of the clamping plate does not exceed the size when the retaining spring is not stretched, ensuring that the retaining spring can be sleeved on the outer periphery of each clamping plate when it is not stretched, thereby improving the convenience of installing the retaining spring on the pressure plate.

[0014] Preferably, the moving mechanism includes a first cylinder for driving the fixed block to slide in the sliding groove, the fixed block is arranged on the piston rod of the first cylinder, and the base is provided with an installation groove for installing the first cylinder, and the installation groove is connected to the sliding groove.

[0015] By adopting the above technical solution, the fixing block is driven by the first cylinder, thereby improving the sliding stability of the fixing block, thereby improving the stability of the clamping plate clamping the ball head, and improving the stability of the clamping plate in use.

[0016] Preferably, the pressing mechanism includes a pressing block and a slider for pressing the retaining spring, the pressing block is arranged on the side of the fixed block away from the base, the pressing block is provided with a fitting groove for the clamping plate to fit, the slider is arranged on the side of the pressing block away from the positioning block, the slider is in contact with the fixed block, a dovetail block is arranged on the side of the slider close to the fixed block, and the fixed block is provided with a sliding cavity for the dovetail block to slide perpendicular to the base.

[0017] By adopting the above technical solution, the pressing block and the clamping plate are fitted together, so that the retaining spring can be pressed out of the clamping plate, and the dovetail block is pressed against the fixed block in the sliding cavity, thereby reducing the situation where the pressing block is separated from the fixed block, thereby improving the stability of the pressing block.

[0018] Preferably, the pressing mechanism also includes a second cylinder for driving the pressing block away from the fixed block, the second cylinder is arranged on the side of the fixed block close to the pressing block, the fixed block is provided with an installation cavity for installing the second cylinder, and the pressing block is arranged on the piston rod of the second cylinder.

[0019] By adopting the above technical solution, the pressing block is driven by the second cylinder, so that the pressing blocks on different fixed blocks press the retaining spring at the same time, so that the retaining spring is always kept horizontal, so that the retaining spring is installed in the retaining spring groove of the ball head, thereby improving the stability of the pressing block.

[0020] Preferably, the clamping plate fits the outer contour of the ball head, and the fixing block is provided with an embedding groove for installing the clamping plate.

[0021] By adopting the above technical solution, the clamping plate fits the outer contour of the ball head, thereby improving the clamping effect of the clamping plate on the ball head. The clamping plate is pressed against the fixed block in the embedded groove, thereby reducing the slippage of the clamping plate on the fixed block, thereby improving the stability of the clamping plate installation.

[0022] Preferably, the positioning block is provided with a slot for inserting the ball head.

[0023] By adopting the above technical solution, the ball head is pressed against the positioning block in the slot, thereby reducing the slippage of the ball head on the positioning block, thereby improving the stability of the ball head installation and the convenience of the retaining spring installation.

The positioning block 2 is integrally arranged on the base 1, and a slot 21 for inserting the ball head 7 is provided on the positioning block 2. The fixed block 3 is symmetrically arranged on a side of the base 1 close to the positioning block 2 with respect to the positioning block 2. The symmetrically arranged fixed blocks 3 are evenly distributed along the circumferential direction of the positioning block 2. The fixed blocks 3 are symmetrically provided with retreat grooves 33 for the adjacent fixed blocks 3 to close. In this embodiment, four fixed blocks 3 are provided. The base 1 is provided with a sliding groove 11 for the fixed block 3 to slide. The sliding groove 11 is symmetrically arranged with respect to the positioning block 2. The moving mechanism 4 is arranged on a side of the base 1 close to the fixed block 3. The moving mechanism 4 is used to drive the fixed block 3 to approach and move away from the ball head 7 in the sliding groove 11.

[0036] Reference Figure 2 and Figure 3 The clamping spring assembly mechanism of the present application further includes a clamping plate 5 and a pressing mechanism 6. The clamping plate 5 is arranged on the side of the fixed block 3 close to the positioning block 2. The outer periphery of the clamping plate 5 is used to open the clamping spring 8, and the inner periphery of the clamping plate 5 is used to abut against the ball head 7. The pressing mechanism 6 is arranged on the side of the fixed block 3 close to the clamping spring 8. The pressing mechanism 6 is used to press the clamping spring 8 so that the clamping spring 8 slides from the outer periphery of the clamping plate 5 to the ball head 7. The pressing mechanism 6 is provided with a retreat cavity 64 for the adjacent pressing mechanisms 6 to close.

[0037] Reference Figure 3 and Figure 4 The pressing mechanism 6 includes a pressing block 61, a slider 62 and a second cylinder 63. The pressing block 61 is arranged on the side of the fixed block 3 away from the base 1, and a retreat cavity 64 is provided on the pressing block 61. The pressing block 61 is used to press the retaining spring 8 so that the retaining spring 8 slides from the clamping plate 5 to the ball head 7. A fitting groove 611 for the clamping plate 5 to fit is provided on the side of the pressing block 61 close to the clamping plate 5. The slider 62 is fixed to the side of the pressing block 61 close to the fixed block 3 by bolts, and the slider 62 contacts the fixed block 3. A dovetail block 621 is integrally provided on the side of the slider 62 close to the fixed block 3, and a sliding cavity 31 is provided on the fixed block 3 for the dovetail block 621 to slide perpendicularly to the base 1. The second cylinder 63 is arranged on one side of the fixed block 3 close to the pressure block 61. The fixed block 3 is provided with an installation cavity 32 for installing the second cylinder 63. The pressure block 61 is welded to the piston column of the second cylinder 63. The second cylinder 63 is used to drive the pressure block 61 away from the fixed block 3. The sliding direction of the pressure block 61 is parallel to the sliding direction of the dovetail block 621.

When the ball head 7 is inserted into the slot 21, the side of the clamping plate 5 away from the base 1 is flush with the lower edge of the retaining spring groove 71. When the pressing mechanism 6 drives the retaining spring 8 to leave the clamping plate 5, the retaining spring 8 just enters the retaining spring groove 71. When the clamping plate 5 is a straight plate, it can be directly welded to the fixing block 3. In this embodiment, the clamping plate 5 fits the outer contour of the ball head 7 to improve the clamping effect of the ball head 7. The fixing block 3 is provided with an embedding groove 34 for installing the clamping plate 5. The clamping plate 5 is welded to the fixing block 3 in the embedding groove 34.

[0040] Usage process:

[0041] 1. The first cylinder 41 drives the fixing block 3 to approach the positioning block 2 so that the outer side of the clamping plate 5 does not exceed the inner ring of the clamping spring 8. The clamping spring 8 is manually sleeved onto the outer side of the clamping plate 5. At this time, the clamping spring 8 contacts the pressing block 61.

[0042] 2. The first cylinder 41 drives the fixing block 3 away from the positioning block 2 so that the clamping spring 8 is stretched open by the force of the clamping plate 5 in the radial direction. The first cylinder 41 drives the fixing block 3 until the inner periphery of the clamping plate 5 just contacts the outer contour of the ball head 7;

[0043] 3. Insert the ball head 7 into the slot 21. At this time, the clamping plate 5 contacts the ball head 7, and the side of the clamping plate 5 away from the base 1 is flush with the lower edge of the retaining ring slot 71.

[0044] 4. The second cylinder 63 drives the pressing block 61 away from the fixing block 3 to make the retaining spring 8 leave the clamping plate 5. After leaving the clamping plate 5, the retaining spring 8 recovers its shape, is tightened and enters the retaining spring groove 71, and the retaining spring 8 is pressed against the ball head 7 in the retaining spring groove 71 to reduce the slippage of the retaining spring 8 on the ball head 7.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
