Description

Technical Field

[0001] The utility model relates to a device for connecting a platform and tooling placed thereon, belonging to the field of machinery. Background Art

[0002] With the development of science and technology, more and more work can be done by robots. Placing the workpiece on the welding platform and welding it by robots is one of the development directions of the mechanical processing industry, and the reliability of robot welding is recognized by people.

[0003] At present, workpieces that need to be welded are fixed to a robotic welding platform by a tooling. The existing threaded connection between the tooling and the welding platform has the following disadvantages: First, since the existing robotic welding platform is relatively large and heavy, it is very inconvenient to fix the tooling to the top of the welding platform from the bottom; Second, when precise positioning requires downward pressure through a cylinder, the threaded connection has poor reliability, so the tooling is prone to shaking after being subjected to a relatively large reverse thrust, and the reliability of the connection between the tooling and the welding platform will directly affect the subsequent welding quality of the workpiece.

[0004] Therefore, there is an urgent need for a device that can reliably connect the tooling to the welding platform from above the welding platform. Summary of the Invention

[0005] The problem to be solved by the present invention is to provide a connection device between a tool and a welding platform, which can conveniently connect the tool and the welding platform from above. At the same time, the connection device of the present invention does not shake the tool even when the cylinder is pressed down, thereby ensuring a reliable connection between the tool and the welding platform and ensuring the quality of subsequent workpiece welding.

[0006] The utility model discloses a connecting device for a tooling and a welding platform, comprising a fixing hook and a nut; the upper portion of the fixing hook is a threaded section, and the lower portion is a combination of a square rod and a hook, and the nut is screwed onto the threaded section of the fixing hook; the mounting holes of both the platform and the tooling are larger than the transverse dimension of the lower portion of the fixing hook, the square rod of the fixing hook is closely abutted against the holes of the welding platform and the tooling, and the hook hooks the bottom surface of the welding platform.

[0007] Furthermore, the upper surface of the hook of the fixed hook is a plane, which is in close contact with the lower plane of the welding platform.

[0008] Furthermore, the connecting device also includes an anti-slip baffle, which includes a channel steel. The channel steel is located on the side of the square rod. The width of the channel steel + the width of the square rod = the aperture of the mounting holes of the welding platform and the tooling.

[0009] Furthermore, the anti-slip baffle also includes a flat washer, which is fixed on the channel steel, and the two are eccentric.

[0010] Furthermore, the connecting device also includes a large washer, which is arranged between the anti-slip baffle and the nut.

[0011] The advantages of the connecting device of the present invention are: first, after the connecting device enters the welding platform from above the tooling and the welding platform, it hooks the platform of the welding platform through the fixed hook, thereby realizing convenient and reliable fixed connection between the tooling and the welding platform from above the welding platform; second, the hook is tightly fitted and pressed by the upper plane and the lower plane of the welding platform, and under the joint action of the channel steel and the square rod, the connecting device has no shaking gap relative to the platform and the tooling, that is, the workpiece, thereby effectively preventing the fixed hook from slipping in the hole of the welding platform and falling out of the hole, so that even if the cylinder presses down the tooling, it will not shake, thereby making the tooling and the welding platform reliably connected, ensuring the welding quality of subsequent workpieces.

[0017] Example 1

[0018] from Figure 1 、 Figure 2 、 Figure 3 It can be seen that the connection device between the tooling and the welding platform of the utility model includes a fixing hook 3 and a nut 6; the upper part of the fixing hook 3 is a threaded section 31, and the lower part is a combination of a square rod 32 and a hook 33, and the nut 6 is screwed on the threaded section 31 of the fixing hook 3; the mounting holes of both the platform 1 and the tooling 2 are larger than the lateral dimension of the lower part of the fixing hook 3, the square rod 32 of the fixing hook 3 is close to the holes of the welding platform 1 and the tooling 2, and the hook 33 hooks the bottom surface of the welding platform 1.

[0019] When the tooling 2 has been placed on the welding platform 1 and the mounting holes of the two are aligned, use the connection device of the present invention: first assemble the fixing hook 3 and the nut 6 together in sequence, so that the nut 6 is located at the top position of the fixing hook 3, and then extend the fixing hook 3 into the mounting holes of the tooling 2 and the welding platform 1. When the hook 33 of the fixing hook 3 extends out of the mounting hole of the welding platform 1, the fixing hook 3 is then translated and the nut 6 is locked when its hook 33 hooks the bottom surface of the welding platform 1.

[0020] The connecting device of the utility model enters the welding platform from above the tooling 2 and the welding platform 1 and hooks the platform of the welding platform 1 through the hook 33 of the fixing hook 3, thereby reliably and fixedly connecting the tooling 2 and the welding platform 1.

[0021] Example 2

[0022] from Figure 1 、 Figure 2 、 Figure 3 It can be seen that the connection device between the tooling and the welding platform of the present invention has the following features: the upper surface of the hook 33 of the fixing hook 3 is a plane, which is in close contact with the lower plane of the welding platform 1 .

[0023] The top surface of the hook 33 of the fixing hook 3 is flat, which increases the contact area between the fixing hook 33 and the lower surface of the welding platform 1, ensuring that the fixing hook 33 and the welding platform 1 are tightly attached and pressed together. In this way, even if the cylinder presses down on the tooling, the tooling will not shake under the relatively large reverse thrust, thereby ensuring the quality of subsequent workpiece welding.

[0024] Example 3

[0025] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 It can be seen that the connection device between the tooling and the platform of the present invention: it also includes an anti-slip baffle 4, the anti-slip baffle 4 includes a channel steel 41, the channel steel 41 is located on the side of the square rod 32, and the width of the channel steel 41 + the width of the square rod 32 = the aperture of the welding platform 1 and the tooling 2.

[0026] Under the joint action of the channel steel 41 and the square rod 32, there is no gap for shaking in the connecting device relative to the platform 1 and the tooling 2, which can effectively prevent the fixing hook 3 from slipping in the hole of the welding platform 1 and falling out of the hole. In this way, even if the cylinder presses down the tooling, it will not shake, thereby ensuring the reliability of the connection between the tooling and the welding platform.

[0027] Example 4

[0028] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4It can be seen that the connection device between the tooling and the welding platform of the present invention: the anti-slip baffle 4 also includes a flat washer 42, and the flat washer 42 is fixed on the channel steel 41, and the two are eccentric.

[0029] The channel steel 41 is put on the fixing hook 3 through the flat washer 42 to prevent it from falling off the fixing hook 3, thereby ensuring the position of the channel steel 41 relative to the fixing hook 3. In this way, under the joint action of the channel steel 41 and the square rod 32, the connecting device has no shaking gap relative to the platform 1 and the tooling 2, which can effectively prevent the fixing hook 3 from slipping in the hole of the welding platform 1 and falling out of the hole. In this way, even if the cylinder presses down the tooling, it will not shake, thereby ensuring the reliability of the connection between the tooling and the welding platform.

[0030] Example 5

[0031] from Figure 1 、 Figure 2 It can be seen that the connection device between the tooling and the welding platform of the present invention further includes a large gasket 5 , which is arranged between the anti-slip baffle 4 and the nut 6 .

[0032] When the nut 6 is tightened, the large washer 5 is pressed against the anti-slip baffle 4, thereby increasing the reliability of the tightening.

[0033] When using the connection device of the utility model Figure 5 As shown, first assemble the fixing hook 3, the anti-slip baffle 4, the large gasket 5, and the nut 6 together in sequence, with the nut 6 located at the top position of the fixing hook 3 (as shown in 5a), and then extend the fixing hook 3 into the mounting holes of the tooling 2 and the welding platform 1. When the hook 33 of the fixing hook 3 extends out of the hole of the welding platform 1, the fixing hook 3 is then translated until the hook 33 hooks the bottom surface of the welding platform 1 (as shown in 5b), and the anti-slip baffle 4 is placed into the mounting hole. The channel steel 41 and the fixing hook 3 are pressed together to tighten the hole, and the flat gasket 42 is located on the top surface of the welding platform 1 (as shown in 5c). Finally, the nut 6 is tightened to press the large gasket 5 against the anti-slip baffle 4 (as shown in 5d).

[0034] The advantages of the connecting device of the present invention are: first, after the connecting device enters the welding platform from above the tooling 2 and the welding platform 1, it hooks the platform of the welding platform 1 through the fixing hook 3, thereby realizing a reliable fixed connection between the tooling 2 and the welding platform 1; second, the hook 33 is tightly fitted and pressed by the upper plane and the lower plane of the welding platform 1, and under the joint action of the channel steel 41 and the square rod 32, the connecting device has no shaking gap relative to the welding platform 1 and the tooling 2, thereby effectively preventing the fixing hook 3 from slipping in the hole of the welding platform 1 and falling out of the hole, so that even if the cylinder presses down the tooling, it will not shake, so that the tooling and the welding platform are reliably connected, ensuring the welding quality of subsequent workpieces.
