Description

Technical Field

[0001] The utility model relates to the technical field of automatic welding production lines, and particularly to a pushing mechanism, an automatic welding tooling and an automatic welding production line device. Background Art

[0002] At present, using an automatic welding tooling to position and fix welding workpieces can greatly improve the positioning and clamping efficiency and can be applied to an automatic welding production line. Especially for plate-shaped welding workpieces, the role of efficient automatic welding is more prominent.

[0003] For the positioning and clamping of plate-shaped workpieces, on an automatic welding tooling, a lateral pushing device is generally used to position and push the two plate-shaped workpieces from the four sides, that is, to position and push the two plate-shaped workpieces from the front, back, left, and right respectively to prevent the heat deformation during welding from affecting the welding quality at the butt joint of the two plate-shaped workpieces.

[0004] However, the applicable plate size range of the lateral pushing device of the existing automatic welding tooling is small. For plate-shaped workpieces with large size changes, effective positioning and pushing cannot be performed on the automatic welding tooling, resulting in a limited clamping range of the automatic welding tooling, restricting the range of welding workpiece types of the automatic welding production line. It can only automatically clamp thick plate-shaped workpieces and ensure their positioning and clamping accuracy, while thin plate-shaped workpieces cannot be effectively positioned and clamped. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is that the applicable plate size range of the lateral pushing device of the existing automatic welding tooling is small, resulting in a limited clamping range of the automatic welding tooling and only being able to position and clamp thick plate-shaped workpieces.

[0006] To solve the above problems, the utility model provides a pushing mechanism for an automatic welding tooling. A concave structure is provided on the top surface of the workbench of the automatic welding tooling. The concave structure is strip-shaped, and a plate-shaped workpiece is placed on the workbench and covers one end of the concave structure.

[0007] The pushing mechanism includes:

[0008] A telescopic driver is arranged beside the workbench of the automatic welding tooling, and the telescopic direction of the telescopic driver is consistent with the length direction of the concave structure; and

[0009] A pushing arm is connected to the telescopic component of the telescopic driver. The pushing arm is used to push the plate-shaped workpiece. The pushing arm is located above the concave structure, and a first protrusion is provided at the bottom end of the pushing arm. The first protrusion protrudes downward and is used to move within the concave structure.

[0010] Optionally, the recessed structure is a long through-hole, and one end of the recessed structure communicates with the side wall of the workbench.

[0011] Optionally, the telescopic driver is a cylinder piston mechanism.

[0012] Optionally, the pushing mechanism further includes a protective cover, the protective cover is arranged above the telescopic driver, the protective cover is detachably connected to the pushing arm, and the protective cover is used to block the piston rod extended by the telescopic driver.

[0013] Optionally, there are two recessed structures, which are arranged in parallel with each other, there are two first protrusions, and the first protrusions are arranged in one-to-one correspondence with the recessed structures.

[0014] Optionally, the pushing arm is a plate-shaped member arranged vertically.

[0015] Two second protrusions are arranged on the pushing surface of the pushing arm, the second protrusions protrude towards the plate-shaped workpiece, the second protrusions are strip-shaped and extend vertically, and the first protrusions are located below the second protrusions.

[0016] Optionally, the pushing arm, the first protrusion and the second protrusion are of an integrally formed structure.

[0017] Optionally, the pushing mechanism further includes a connecting plate, and the connecting plate connects the telescopic driver and the workbench together.

[0018] In addition, the present invention further provides an automatic welding tooling, including the pushing mechanism.

[0019] In addition, the present invention further provides an automatic welding production line equipment, and the automatic welding production line equipment includes the automatic welding tooling.

[0020] The technical effects of the present invention at least include:

[0021] The telescopic component of the telescopic driver extends along the length direction of the concave structure, so that the pushing arm pushes the plate-shaped workpiece, and at the same time, the first protrusion at its bottom also moves together with the pushing arm in the concave structure. In this way, when the plate-shaped workpiece with a relatively thin thickness is pushed, since the first protrusion is located in the concave structure and the first protrusion is connected to the pushing arm, no matter how thin the plate-shaped workpiece is, it can be pushed by the pushing arm and the first protrusion. After welding is completed, the telescopic driver retracts the telescopic component again, so that the first protrusion retracts together with the pushing arm, enabling the first protrusion to reciprocate within the concave structure. Thus, it prevents the situation that the plate-shaped workpiece is too thin and gets stuck between the pushing arm and the workbench, resulting in ineffective pushing. Therefore, it realizes an increase in the applicable plate size range of the lateral pushing device of the automatic welding tooling, enabling the automatic welding tooling to position and clamp plate-shaped workpieces with various different thicknesses.

[0031] See Figure 1 and Figure 2 In this embodiment, a pushing mechanism is provided for an automatic welding fixture. A concave structure 11 is formed on the top surface of the workbench 1 of the automatic welding fixture. The concave structure 11 is strip-shaped, and a plate-shaped workpiece is placed on the workbench 1 and covers one end of the concave structure 11.

[0032] The pushing mechanism includes:

[0033] A telescopic driver 2 is arranged beside the workbench 1 of the automatic welding fixture, and the telescopic direction of the telescopic driver 2 is consistent with the length direction of the concave structure 11; and

[0034] A pushing arm 3 is connected to the telescopic component of the telescopic driver 2. The pushing arm 3 is used to push the plate-shaped workpiece. The pushing arm 3 is located above the concave structure 11, and a first protrusion 31 is provided at the bottom end of the pushing arm 3. The first protrusion 31 protrudes downward, and the first protrusion 31 is used to move within the concave structure 11.

[0035] It should be noted that the telescopic driver 2 in this embodiment can be a piston hydraulic cylinder mechanism, a piston air cylinder mechanism, or an electric push rod mechanism, as long as it can achieve linear telescopic driving.

[0036] During use, the plate-shaped workpiece is placed on the workbench 1 by a robotic arm and covers the concave structure 11. Other pushing devices of the automatic welding fixture position and push it from other directions of the plate-shaped workpiece, such as the front-and-back direction or the left-and-right direction, and then the pushing mechanism of the present invention is used to push the plate-shaped workpiece from the set direction.

[0037] Specifically, the telescopic member of the telescopic driver 2 extends along the length direction of the concave structure 11, so that the pushing arm 3 pushes the plate-shaped workpiece, and at the same time, the first protrusion 31 at its bottom also moves together with the pushing arm 3 in the concave structure 11. In this way, when the plate-shaped workpiece with a relatively thin thickness is pushed, since the first protrusion 31 is located in the concave structure 11 and the first protrusion 31 is connected to the pushing arm 3, no matter how thin the plate-shaped workpiece is, it can be pushed by the pushing arm 3 and the first protrusion 31. After welding is completed, the telescopic driver 2 retracts the telescopic member, so that the first protrusion 31 retracts together with the pushing arm 3, enabling the first protrusion 31 to reciprocate within the concave structure 11. Thus, it prevents the situation that the plate-shaped workpiece with an overly thin thickness is stuck between the pushing arm 3 and the workbench 1, resulting in ineffective pushing. Therefore, the applicable plate size range of the lateral pushing device of the automatic welding tooling is increased, enabling the automatic welding tooling to position and clamp plate-shaped workpieces of various different thicknesses.

[0038] Preferably, the pushing mechanism in this embodiment is used to push the arc striking plate, and the plate thickness range of the arc striking plate can be 2 mm - 14 mm.

[0039] See Figure 1 and Figure 2 Furthermore, the concave structure 11 is a long strip-shaped through hole, and one end of the concave structure 11 communicates with the side wall of the workbench 1.

[0040] The long strip-shaped through hole is convenient for processing and manufacturing, and the long strip-shaped through hole has no influence on the protrusion height of the first protrusion 31, enabling the protrusion height of the first protrusion 31 to be unrestricted, which is convenient for manufacturing and assembly.

[0041] See Figure 1 and Figure 2 Furthermore, the telescopic driver 2 is a cylinder piston mechanism.

[0042] Utilizing the characteristics of the cylinder piston mechanism with rapid response, especially the rapid telescoping of the piston, enables the pushing arm 3 to quickly push the plate-shaped workpiece.

[0043] See Figure 1 and Figure 2 Furthermore, the pushing mechanism further includes a protective cover. The protective cover is arranged above the telescopic driver 2. The protective cover is detachably connected to the pushing arm 3, and the protective cover is used to shield the piston rod extended by the telescopic driver 2.

[0044] Preferably, the protective cover is a rectangular plate, and one end of its long side is detachably connected to the top of the pushing arm 3 through a threaded connector.

[0045] When pushing a plate-shaped workpiece with a small length, the piston rod extends a large amount. Moreover, during the welding process, the splashed welding slag has a high temperature, and it is easy to stick together when it falls on the piston rod. After the piston rod retracts into the cylinder, it is easy to damage the cylinder. Therefore, the protective cover is detachably connected to the pushing arm 3, and the protective cover is used to block the splashed welding slag from falling on the piston rod, thereby effectively protecting the telescopic driver 2.

[0046] See Figure 1 and Figure 2 Furthermore, there are two of the concave structures 11, and they are arranged in parallel. There are two of the first protrusions 31, and the first protrusions 31 are arranged in one-to-one correspondence with the concave structures 11.

[0047] The two first protrusions 31 push the plate-shaped workpiece more smoothly.

[0048] See Figure 1 and Figure 2 Furthermore, the pushing arm 3 is a plate-shaped member arranged vertically.

[0049] On the pushing surface of the pushing arm 3, there are two second protrusions 32. The second protrusions 32 protrude towards the plate-shaped workpiece. The second protrusions 32 are strip-shaped and extend vertically. The first protrusions 31 are located below the second protrusions 32.

[0050] By combining the two second protrusions 32 and the two first protrusions 31, the effective pushing of the plate-shaped workpiece is realized.

[0051] See Figure 1 and Figure 2 Furthermore, the pushing arm 3, the first protrusion 31, and the second protrusion 32 are of an integrally formed structure.

[0052] In this way, it is convenient to process and manufacture the pushing arm 3, the first protrusion 31, and the second protrusion 32.

[0053] Preferably, the pushing arm 3 is a plate-shaped member, and the first protrusion 31 and the second protrusion 32 are formed by bending the pushing arm 3.

[0054] See Figure 1 and Figure 2 Furthermore, the pushing mechanism further includes a connecting plate 4, and the connecting plate 4 connects the telescopic driver 2 and the workbench 1 together.

[0055] By using the connecting plate 4, the telescopic driver 2 is arranged beside the workbench 1 of the automatic welding tooling.

[0056] In addition, this embodiment also provides an automatic welding tooling, including the pushing mechanism described above.

[0057] Since the technical effects achieved by this automatic welding tooling are the same as those of the pushing mechanism described above, no further explanation of the automatic welding tooling will be provided.

[0058] In addition, this embodiment also provides an automatic welding production line equipment, and the automatic welding production line equipment includes the above-mentioned automatic welding tooling.

[0059] Since the technical effects achieved by this automatic welding production line equipment are the same as those of the pushing mechanism described above, no further explanation of the automatic welding production line equipment will be provided.

[0060] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present utility model.
