[0002] In the automobile manufacturing process, injection molding machines are used in the resin workshop to manufacture bumpers. After the injection molding process is completed, a robotic arm enters the mold of the molding machine to remove the bumper.

[0003] However, the existing technology has the following problems: after installing a new mold, the shrinkage rate of plastic parts often changes, the contact position of the gripper is inconsistent, the support on the robot arm is easy to loosen, which causes the angle of the robot arm picking up the part to change, the product falls into the mold, and the mold generates 3,000 tons of mold closing pressure during the mold closing process, squeezing and damaging the high-value molding mold, and in severe cases, causing mold damage and affecting production.

[0004] Existing technical solutions may use ordinary fastening devices, but these devices are difficult to keep secure for long periods of time under continuous vibration and frequent use.

[0005] Therefore, it is necessary to design an anti-loosening connection component to prevent the connection from becoming loose. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an anti-loosening connection component to prevent loosening of the connection.

[0007] The present invention provides an anti-loosening connection assembly, including a first connector, a second connector, a first gasket, and a second gasket. The first gasket is provided with a first limiting part for limiting the first connector, and the second gasket is provided with a second limiting part for limiting the second connector. The first connector, the first gasket, the second connector, and the second gasket are all provided with connecting through holes.

[0008] When the connecting holes of the first connector, the first gasket, the second connector, and the second gasket are aligned, and the angle between the first gasket and the second gasket is set, the first gasket and the second gasket are fixedly connected relative to each other.

[0009] Furthermore, the first limiting part is a straight edge, and the first connecting member includes a first connecting seat, on which a first vertical surface is provided, and the straight edge contacts and limits the first vertical surface.

[0010] Furthermore, the second limiting part is a straight edge, and the second connecting member includes a second connecting seat, on which a second vertical surface is provided, and the straight edge contacts and limits the second vertical surface.

[0011] Furthermore, both the first gasket and the second gasket are D-shaped gaskets, both the first limiting portion and the second limiting portion are straight edges, and both the first connector and the second connector are provided with vertical surfaces that mate with the straight edges.

[0012] Furthermore, the first connector also includes a connecting rod, which is connected to the side of the first connector.

[0013] Furthermore, the second connector has mounting holes along a direction perpendicular to the connecting through hole.

[0014] Furthermore, after the angle between the first gasket and the second gasket is set, the first gasket and the second gasket are welded together.

[0015] Furthermore, serrations are provided on the contact surfaces between the first gasket and the second gasket.

[0016] Furthermore, the first gasket and the second gasket are made of 45# steel.

[0017] Furthermore, the first connector and the second connector are made of aluminum alloy.

[0018] The above technical solution has the following beneficial effects:

[0019] In this invention, the first limiting part of the first gasket is limited to the first connecting member, and the second limiting part of the second gasket is limited to the second connecting member. When the angle between the first and second gaskets is adjusted, the first and second gaskets are fixedly connected. This invention achieves locking between the first and second connecting members through multi-point locking, preventing loosening; and because the multiple locking points are distributed, the load on each point is reduced, thereby improving the overall strength and stability.

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0030] It is readily understood that, based on the technical solution of this utility model, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0031] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0032] In some embodiments of this utility model, such as Figures 1-2 As shown, the anti-loosening connection assembly includes a first connector 1, a second connector 2, a first gasket 3, and a second gasket 4. The first gasket 3 is provided with a first limiting part 31 for limiting the first connector 1, and the second gasket 4 is provided with a second limiting part 41 for limiting the second connector 2. The first connector 1, the first gasket 3, the second connector 2, and the second gasket 4 are all provided with connecting through holes.

[0033] When the connecting holes of the first connector 1, the first gasket 3, the second connector 2, and the second gasket 4 are aligned, and the angle between the first gasket 3 and the second gasket 4 is set, the first gasket 3 and the second gasket 4 are fixedly connected relative to each other.

[0034] Specifically, such as Figure 1 As shown, the first connector 1, the first gasket 3, the second connector 2, and the second gasket 4 are all provided with connecting through holes and are aligned along the axial direction. The bolt 5 passes through the connecting through holes to connect and fasten the first connector 1, the first gasket 3, the second connector 2, and the second gasket 4 along the axial direction.

[0035] like Figure 2As shown, the first gasket 3 is provided with a first limiting part 31, which is used to limit the first connector 1 and prevent the first gasket 3 from rotating relative to the first connector 1.

[0036] The second gasket 4 is provided with a second limiting part 41, which is used to limit the second connector 2 and prevent the second gasket 4 from rotating relative to the second connector 2.

[0037] During installation, first pass bolt 5 through the connecting through holes on the second connector 2, the second washer 4, the first washer 3, and the first connector 1 in sequence, without tightening bolt 5 at this time. Adjust the angle between the first washer 3 and the second washer 4. Since the first washer 3 is already locked to the first connector 1 by the first limiting part 31, and the second washer 4 is already locked to the second connector 2 by the second limiting part 41, adjusting the angle between the first washer 3 and the second washer is equivalent to adjusting the angle between the first connector 1 and the second connector 2. After the angle adjustment is completed, fix the first washer 3 and the second washer 4 relative to each other, thereby achieving the locking between the first washer 3 and the second washer 4. Finally, the entire anti-loosening connection assembly is locked, and there will be no relative rotation between the first connector 1 and the second connector 2.

[0038] The first connector 1 and the second connector 2 are used to connect the robot and the support respectively. The anti-loosening component prevents the robot from becoming loose from the support.

[0039] In this embodiment, the locking between the first connector 1 and the second connector 2 is achieved through multi-point locking between the first connector 1 and the first gasket 3, between the second connector 2 and the second gasket 4, and between the first gasket 3 and the second gasket 4, preventing loosening; and because the multiple locking points are distributed in a dispersed manner, the load on each point is reduced, thereby improving the overall strength and stability.

[0040] Furthermore, such as Figure 2 As shown, the first limiting part 31 has a straight edge, and the first connecting member 1 includes a first connecting seat 11. The first connecting seat 11 is provided with a first vertical surface 111, and the straight edge contacts and limits the first vertical surface 111.

[0041] Specifically, the first connecting seat 11 includes a bearing surface 112 for placing the first gasket 3, and a connecting through hole is provided on the bearing surface 112. The bearing surface 112 is perpendicular to the first vertical surface 111.

[0042] When the first gasket 3 is placed on the bearing surface 112, the straight edge of the first limiting part 31 contacts the first vertical surface 111, thus restricting the rotation of the first gasket 3 relative to the first connecting member 1.

[0043] Furthermore, such as Figure 2As shown, the second limiting part 41 has a straight edge, and the second connecting member 2 includes a second connecting seat 21. The second connecting seat 21 is provided with a second vertical surface 211, and the straight edge contacts and limits the second vertical surface 211.

[0044] Similarly, the second connecting seat 21 is also provided with a bearing surface for placing the second gasket 4. When the second limiting part 41 contacts the second vertical surface 211, it is used to restrict the rotation of the second gasket 4 relative to the second connecting member 2.

[0045] Optionally, the first limiting part 31 and the second limiting part 41 may also be sawtooth edges, arc edges, or other irregularly shaped edges. Correspondingly, the first connecting seat 11 and the second connecting seat 21 are provided with limiting surfaces of corresponding shapes. When the two are in contact, they are used to limit the movement of the first gasket 3 and the second gasket 4.

[0046] Furthermore, such as Figure 2 As shown, the first gasket 3 and the second gasket 4 are both D-shaped gaskets, the first limiting part 31 and the second limiting part 41 are both straight edges, and the first connector 1 and the second connector 2 are both provided with vertical surfaces that cooperate with the straight edges.

[0047] The first gasket 3 and the second gasket 4 are both D-shaped gaskets, each including a straight edge and a rounded edge. The straight edge serves as a limit, while the rounded edge facilitates the adjustment of the rotation angle between the first gasket 3 and the second gasket 4, avoiding interference during the adjustment process.

[0048] Furthermore, such as Figure 2 As shown, the first connector 1 also includes a connecting rod 12, which is connected to the side of the first connector 11 and is used to connect with the robot arm.

[0049] Furthermore, such as Figure 2 As shown, the second connecting seat 21 has a mounting hole 212 along the direction perpendicular to the connecting through hole 213, and the mounting hole 212 is used to connect with the bracket.

[0050] Optionally, the first connector 1 and the second connector 2 can also be other structures, not limited to connecting the robot and the support, but also used to connect other components.

[0051] In this embodiment, after the angle between the first gasket 3 and the second gasket 4 is set, the first gasket 3 and the second gasket 4 are welded together.

[0052] Specifically, both the first gasket 3 and the second gasket 4 are flat gaskets, and in particular, the contact surface between the first gasket 3 and the second gasket 4 is a plane, allowing the first gasket 3 and the second gasket 4 to be adjusted to any angle. After the first gasket 3 and the second gasket 4 are adjusted to a suitable angle, they are fixedly connected by welding.

[0053] When a new robotic arm needs to be reinstalled or the angle needs to be readjusted, only two shims need to be replaced. The first and second connectors do not need to be replaced. Since the shims are inexpensive, the replacement cost is also low.

[0054] Optionally, serrations can be provided on the contact surfaces between the first washer 3 and the second washer 4. Each rotation of one tooth between the first washer 3 and the second washer 4 adjusts the angle by one level. After adjusting to the appropriate angle, the bolt 5 is tightened to press the toothed surfaces of the first washer 3 and the second washer 4 together, thereby locking the first washer 3 and the second washer 4 together.

[0055] Preferably, the first gasket 3 and the second gasket 4 are made of 45# steel, which has good wear resistance and strength, and is less expensive.

[0056] Preferably, the first connector 1 and the second connector 2 are made of aluminum alloy, which has good compressive and vibration resistance and is lightweight.

[0057] In this invention, the first limiting part of the first gasket is limited to the first connecting member, and the second limiting part of the second gasket is limited to the second connecting member. When the angle between the first and second gaskets is adjusted, the first and second gaskets are fixedly connected. This invention achieves locking between the first and second connecting members through multi-point locking, preventing loosening; and because the multiple locking points are distributed, the load on each point is reduced, thereby improving the overall strength and stability.

[0058] The above description is merely the principle and preferred embodiment of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principle of this utility model, and these modifications should also be considered within the protection scope of this utility model.
