Description

Technical Field

[0001] This utility model belongs to the field of displacement tank processing technology, specifically a displacement tooling. Background Technology

[0002] As a key component in industrial equipment used to store and supply hydraulic or lubricating oil, the positioner tank typically carries the oil in the hydraulic system and withstands certain internal pressures and external loads. To ensure good sealing, structural strength, and service life, welding is usually used to connect the tank's shell to its internal structural components. Welding not only achieves high-strength connections but also effectively prevents problems such as oil leakage and oil contamination.

[0003] Chinese utility model patent CN217890038U discloses a welding fixture for a large-capacity fuel tank partition. The fixture includes a base and a rotating mechanism, which comprises a rotating shaft, a rotating motor, and a welding plate. The welding plate can rotate at multiple angles driven by the rotating shaft, facilitating a smoother welding process. Furthermore, the fixture is equipped with a clamping mechanism that can quickly clamp and fix the fuel tank around its perimeter, eliminating the need for the cumbersome arrangement of traditional clamping cylinders, improving clamping efficiency, reducing equipment costs, and facilitating adjustment to accommodate fuel tanks of different sizes.

[0004] However, this patented tooling still has shortcomings. Its clamping structure uses a large-area clamping plate to clamp the side plates around the oil tank. Although it can adapt to oil tanks of different sizes, it is easy to block the weld area, resulting in blind spots and dead angles for the welding robot, which affects the comprehensiveness and quality of the welding.

[0015] Furthermore, a second reinforcing connecting plate is provided between the supporting plate and the movable plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The drive mechanism is connected to the tooling chassis and is used to push the movable clamping component mounted on the sliding mechanism to achieve the clamping action.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-5 As shown in the embodiment of this utility model, a positioner tooling includes a tooling chassis 1, a driving mechanism 2 is provided on the tooling chassis 1, a movable clamping component 5 is fixedly connected to the driving mechanism 2, support plates 3 are provided on both sides of the tooling chassis 1, a sliding mechanism 4 is provided on each support plate 3, a movable clamping component 5 is fixedly connected to the sliding mechanism 4, and a fixed clamping component 6 is provided between the two support plates 3. The drive mechanism 2 is connected to the tooling chassis 1 and is used to push the movable clamping component 5 installed on the sliding mechanism 4 to achieve the clamping action. The sliding mechanism 4 ensures that the movable clamping component 5 can slide and adjust along the direction of the support plate 3 to meet the clamping requirements of workpieces of different sizes. Since the clamping structure of this tooling does not interfere with the weld area, the welding robot can perform welding operations without obstacles, significantly reducing the amount of manual welding work, improving welding consistency and welding quality. The tooling as a whole uses the movable clamping component 5 and the fixed clamping component 6 to clamp the oil tank 100 on both sides in a small area, avoiding large-area contact that may obstruct the welding area, while reducing the impact on workpiece deformation, enabling the welding robot to cover more weld areas and reduce blind spots.

[0027] In one embodiment, see Figure 1 , Figure 2 and Figure 3As shown, the drive mechanism 2 includes a first fixed plate 21, which is mounted on the tooling chassis 1. A second fixed plate 22 is also mounted on one side of the upper part of the tooling chassis 1. A lead screw 23 is rotatably connected to the first fixed plate 21 and the second fixed plate 22. The two ends of the lead screw 23 pass through the first fixed plate 21 and the second fixed plate 22 respectively, and are supported and fixed by bearings or sleeves. It can rotate under the drive of an external drive source. A lead screw nut 24 is threaded onto the lead screw 23. A drive connecting plate 25 is fixedly connected to the lead screw nut 24. A movable clamping assembly 5 is fixedly connected to the drive connecting plate 25. When the lead screw 23 rotates due to an external drive source (such as a drive motor or an electronic wrench), it drives the threaded lead screw nut 24 to move linearly. The lead screw nut 24 is fixedly connected to the drive connecting plate 25, which in turn drives the movable clamping assembly 5 connected to it to slide back and forth, thereby clamping or releasing the workpiece.

[0028] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the movable clamping assembly 5 includes a movable plate 51, which is fixedly connected to the drive connecting plate 25. A first clamping plate body 52 is provided on the upper side of the movable plate 51. The movable plate 51 is a long strip of metal plate with a certain rigidity and thickness. Its lower end is connected to the drive connecting plate 25 by screws. The movable plate 51 moves with the drive mechanism to carry and drive the clamping plate to move. The first clamping plate body 52 is provided on the upper side of the movable plate 51, specifically a small area pressure plate, which is fixedly connected to the movable plate 51 by bolts. In the initial state, the screw 23 rotates and drives the screw nut 24 to move, and the drive connecting plate 25 and the movable plate 51 on it slide towards the oil tank 100. The movable plate 51 drives the first clamping plate body 52 to approach the oil tank 100. When the first clamping plate body 52 contacts the outer wall of the bottom shell of the oil tank 100, a small area clamping limit is formed, and the clamping is completed. Reversing the screw 23 can release the clamping.

[0029] In one embodiment, see Figure 1 , Figure 3 and Figure 4 As shown, the upper part of the movable plate 51 is also provided with a first limiting plate 53. The first limiting plate 53 is used to limit the contact of one side of the bottom of the oil tank 100 to prevent it from loosening during the welding process. Unlike the small area pressing of the first clamping plate 52, the first limiting plate 53 mainly plays a role in preventing backward movement, that is, to limit the edge of the oil tank 100 so that it will not move backward when subjected to welding stress.

[0030] In one embodiment, see Figure 1 , Figure 3 and Figure 4 As shown, the sliding mechanism 4 includes a guide rail 41, which is mounted on the support plate 3. Each guide rail 41 is equipped with a guide slider 42, and each guide slider 42 is equipped with a guide connecting plate 43. Each guide connecting plate 43 is fixedly connected to a movable plate 51. A fixed clamping assembly 6 is provided between the two support plates 3. The guide rail 41 of the sliding mechanism 4, mounted on the support plate 3, provides a linear guide path for the movement of the movable plate 51. The guide slider 42, installed on the guide rail 41, can slide smoothly along its direction without shaking or shifting, ensuring precise clamping action. The connecting plate 43 connects the slider and the movable plate 51 into one unit, allowing the movable clamping component 5 to slide back and forth on the guide rail 41 to adjust the clamping position of the movable clamping component 5. The fixed clamping component 6 is set between the two support plates 3 and is fixed in place. The fixed clamping component 6 is used to limit the other side of the bottom of the oil tank 100 in a small area. It forms a clamping cooperation structure with the movable clamping component 5 to limit the bottom side walls of both sides of the oil tank 100 in a small area, avoiding large-area contact that may obstruct the welding area. At the same time, it reduces the impact on workpiece deformation, allowing the welding robot to cover more weld seam areas and reduce blind spots.

[0031] In one embodiment, see Figure 1 , Figure 3 and Figure 4 As shown, the fixed clamping assembly 6 includes a fixed mounting plate 61, which is positioned between two support plates 3. A second clamping plate 62 is provided on the fixed mounting plate 61. The second clamping plate 62 provides a fixed anti-retraction surface or limiting point for the workpiece. Under the clamping action of the movable clamping assembly 5, the workpiece will move towards the fixed clamping assembly 6. The two second clamping plates 62 on the fixed clamping assembly 6 limit the other side of the oil tank 100 in a small area, forming a paired clamping structure with the movable clamping assembly 5, ensuring stable positioning of the workpiece during the welding process and reducing the displacement of the oil tank 100.

[0032] In one embodiment, see Figure 1 , Figure 3 and Figure 4 As shown, both the first limiting plate 53 and the second limiting plate 63 are provided with snap-fit ​​grooves 7. The snap-fit ​​grooves 7 are located on the clamping surfaces of the first limiting plate 53 and the second limiting plate 63 facing the oil tank 100. The width of the grooves is slightly greater than the edge thickness of the oil tank 100, the groove depth is 1~2cm, and the included angle is inclined inward at 5°~15°. The inner groove surface can be provided with anti-slip texture. The snap-fit ​​structure only acts on a small area around the bottom outer edge of the oil tank 100, avoiding large-area compression or interference with the weld seam or key positioning area at the bottom of the oil tank 100, effectively protecting the integrity of the oil tank 100 body and the welding process surface.

[0033] In one embodiment, see Figure 1and Figure 5 As shown, a first reinforcing connecting plate 8 is also provided between the support plate 3 and the fixed mounting plate 61. During the welding process of the oil tank 100, the equipment structure is prone to local deformation or vibration due to the clamping force and operating force. The first reinforcing connecting plate 8 can effectively enhance the connection strength between the support plate 3 and the fixed mounting plate 61, reduce deformation, and improve the stability of the overall device.

[0034] In one embodiment, see Figure 1 and Figure 5 As shown, a second reinforcing connecting plate 9 is also provided between the support plate 3 and the movable plate 51. When the connecting plate is installed, it is arranged obliquely or horizontally with the support plate 3 and the movable plate 51 to construct a stable triangular support structure, ensuring that the movable plate 51 runs stably during movement and clamping, and avoiding clamping offset or loosening during the welding of the oil tank 100.

[0035] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
