Description

Technical Field

[0001] This utility model relates to the field of hydraulic oil tank processing technology, and more specifically, to a fixture for a hydraulic oil tank production device. Background Technology

[0002] The primary function of a hydraulic oil tank is to store hydraulic fluid. It also serves to dissipate heat, allow impurities to settle, and facilitate the escape of air from the fluid. Based on whether the oil level is open to the atmosphere, hydraulic tanks can be classified into open and closed types. Open tanks are used in general hydraulic systems; closed tanks are used underwater and in hydraulic systems with strict requirements for operational stability and noise levels.

[0003] Currently, hydraulic oil tanks require welding during production. During welding, the oil tank needs to be positioned to ensure that it is neat and orderly after welding. The current positioning device can only position and fix the hydraulic oil tank, but cannot flip or rotate it. When welding is required on the other side of the oil tank, manual repositioning and fixing are required, which is cumbersome and inefficient.

[0004] Announcement No. CN219542154U proposes a welding positioning device for hydraulic oil tank processing. This device, through the setting of support and drive mechanisms, clamps and positions the oil tank while realizing automatic flipping of the oil tank, which facilitates welding operations for users and has strong stability and high efficiency. However, there will be obstacles when welding the clamping surfaces on both sides. At this time, the position of the hydraulic oil tank still needs to be manually adjusted before the overall processing can be completed. The comprehensiveness of welding processing needs to be further improved. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a fixture for a hydraulic oil tank production device.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A fixture for a hydraulic oil tank production device includes a processing table, on which a telescopic groove and symmetrically distributed fixed plates are provided. A lifting assembly is provided in the telescopic groove, and a connecting roller and a drive assembly connected to the connecting roller are provided on the lifting assembly. One end of the connecting roller is connected to a placement table, on which an adsorption assembly and two sets of symmetrically distributed limiting blocks are provided. The limiting blocks have rounded corners for fitting with the four corners of the hydraulic oil tank. A clamping and flipping assembly is provided on the fixed plate, and an auxiliary clamping component is provided on the clamping and flipping assembly.

[0008] This device can automatically clamp and rotate the hydraulic oil tank to achieve omnidirectional welding operations. All external surfaces and interior parts of the hydraulic oil tank can be machined without any obstruction during the welding process, further improving welding efficiency.

[0009] Furthermore, the lifting assembly includes an electric push rod and a lifting plate. The electric push rod is symmetrically arranged in the telescopic groove. The electric push rod is connected to the lifting plate. The lifting plate is rotatably connected to a connecting roller and fixedly equipped with a drive assembly.

[0010] The above solution uses a lifting component to raise and lower the placement platform, thereby contacting or disengaging it from the bottom of the hydraulic oil tank. At the same time, the drive component enables the horizontal rotation of the placement platform, thereby rotating the clamping surfaces on both sides of the hydraulic oil tank to the front and rear sides to facilitate subsequent unobstructed processing from all directions.

[0011] Furthermore, the adsorption assembly includes an electromagnetic plate, and an installation groove is provided on the placement platform. An electromagnetic block is provided in the installation groove, which is level with the placement platform, and the electromagnetic block is located at the center of the four limiting blocks.

[0012] The above solution uses an adsorption component to adsorb the bottom of the hydraulic oil tank, thereby ensuring the stability of the hydraulic oil tank during subsequent horizontal rotation and lifting.

[0013] Furthermore, the clamping and flipping assembly includes a first cylinder, a servo motor, a clamping plate, and a second cylinder. The first cylinder is mounted on a fixed plate and connected to the servo motor. The second cylinder is rotatably connected to another fixed plate. The servo motor and the second cylinder are respectively connected to two clamping plates that are facing each other and move synchronously.

[0014] The above solution achieves stable clamping of the hydraulic oil tank and angular deflection in the vertical direction by using a clamping and flipping assembly.

[0015] Furthermore, the auxiliary clamping component is an electromagnetic plate, and an electromagnetic plate is provided on the clamping plate.

[0016] Furthermore, the auxiliary clamping member is a flexible friction layer, and a flexible friction layer is provided on the clamping plate.

[0017] The above solution can further improve the clamping effect on the hydraulic oil tank by using auxiliary clamping components, thus ensuring the safety of the hydraulic oil tank during the subsequent welding process.

[0018] Furthermore, the drive assembly employs gear transmission.

[0019] Furthermore, a six-degree-of-freedom robotic arm is provided on one side of the processing table, and welding equipment is provided on the six-degree-of-freedom robotic arm.

[0020] The above solution achieves omnidirectional automatic welding by using a six-free robotic arm to drive the welding equipment and coordinating with the clamping and tilting of the hydraulic oil tank. This eliminates the need for manual operation of the welding torch, further improving the level of automation.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] Compared to existing technologies, this device, through the cooperation of lifting components, placement platform, limiting block, adsorption components, and clamping and flipping components, can automatically and stably clamp and flip the hydraulic oil tank to achieve omnidirectional welding operations. Furthermore, through the coordinated cooperation of the drive components, all external surfaces and interiors of the hydraulic oil tank can be machined without any obstruction during the welding process, further improving welding efficiency.

The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0028] like Figure 1 and Figure 2As shown, a fixture for a hydraulic oil tank production device includes a processing table 1, on which a telescopic groove 11 and symmetrically distributed fixed plates 3 are provided. A lifting assembly is provided in the telescopic groove 11. A connecting roller 21 and a driving assembly 22 connected to the connecting roller 21 are provided on the lifting assembly.

[0029] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the lifting assembly includes an electric push rod 12 and a lifting plate 13. The electric push rod 12 is symmetrically arranged in the telescopic groove 11. The electric push rod 12 is connected to the lifting plate 13. The lifting plate 13 is rotatably connected to the connecting roller 21 via bearings and a drive assembly 22 is fixedly mounted on it. Specifically, the drive assembly 22 adopts gear transmission and consists of a drive motor, a main gear, and a secondary gear. The working principle is existing technology and will not be described in detail. The lifting assembly realizes the lifting of the placement platform 23, thereby contacting or disengaging it from the bottom of the hydraulic oil tank. At the same time, the drive assembly 22 can realize the horizontal rotation of the placement platform 23, thereby rotating the two clamping surfaces of the hydraulic oil tank to the front and rear sides to facilitate subsequent unobstructed processing from all directions.

[0030] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the adsorption assembly includes an electromagnetic plate, and an installation groove 24 is provided on the placement platform 23. An electromagnetic block 25 that is level with the placement platform 23 is provided in the installation groove 24. The electromagnetic block 25 is located at the center of the four limit blocks 26. The bottom of the hydraulic oil tank is adsorbed by the adsorption assembly, thereby ensuring the stability of the hydraulic oil tank during subsequent horizontal rotation and lifting.

[0031] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the clamping and flipping assembly includes a first cylinder 31, a servo motor 32, a clamping plate 33, and a second cylinder 34. The first cylinder 31 is mounted on a fixed plate 3 and is connected to the servo motor 32. The second cylinder 34 is rotatably connected to another fixed plate 3. The servo motor 32 and the second cylinder 34 are respectively connected to two clamping plates 33 that are facing each other and move synchronously. The clamping and flipping assembly realizes the stable clamping of the hydraulic oil tank and the angular deflection in the vertical direction.

[0032] First embodiment:

[0033] Specific implementation of the first embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the auxiliary clamping component 35 is an electromagnetic plate, and the clamping plate 33 is provided with an electromagnetic plate.

[0034] Second embodiment:

[0035] Specific implementation of the second embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the auxiliary clamping member 35 is a flexible friction layer, and the clamping plate 33 is provided with a flexible friction layer, which is specifically a rubber pad.

[0036] It should be noted that the electric push rod 12, drive assembly 22, electromagnetic block 25, first cylinder 31, servo motor 32, second cylinder 34 and electromagnetic plate are all electrically connected to the controller, which is not shown in the figure.

[0037] The working process of this utility model is as follows:

[0038] In the initial state, the electric push rod 12 is in the shortest range retracted state. At this time, the hydraulic oil tank to be welded is placed on the placement table 23. The hydraulic oil tank is not shown in the figure and the upper end of the hydraulic oil tank is not blocked. During the placement process, the four corners of the bottom of the hydraulic oil tank contact the four limit blocks 26 in sequence. At this time, the placement position of the hydraulic oil tank can be limited. After the position is limited, the controller controls the electromagnetic block 25 to be energized to achieve adsorption of the bottom of the hydraulic oil tank.

[0039] The controller then controls the electric push rod 12 to operate, which in turn drives the placement platform 23 to rise to a preset height and then stops. The controller then controls the movement of the fixing component to clamp the middle area of ​​both sides of the hydraulic oil tank. During this process, the auxiliary clamping component 35 can further improve the clamping effect and ensure the safety of the hydraulic oil tank during the subsequent welding process. After clamping is completed, the controller controls the solenoid block 25 to be de-energized. Then, the placement platform 23 moves away from the bottom of the hydraulic oil tank under the action of the electric push rod 12, and the partial welding of the hydraulic oil tank can be realized. When it is necessary to weld the bottom area of ​​the hydraulic oil tank, the fixing component works to achieve the angle deflection of the hydraulic oil tank to facilitate processing.

[0040] Finally, when welding is required on both sides of the hydraulic oil tank, the hydraulic oil tank is first moved back to its initial vertical position (i.e., open end facing upwards). Then, the controller controls the electric push rod 12 to rise again so that the placement platform 23 re-contacts the bottom of the hydraulic oil tank. Then, the controller controls the electromagnetic block 25 to be energized to re-adhere to the bottom of the hydraulic oil tank. At the same time, the fixing component releases the clamping fixation of the hydraulic oil tank. Then, the controller controls the drive component 22 to work to realize the overall rotation of the placement platform 23. At this time, the previous clamping surface will move to the front and rear sides (rotate 90 degrees). During the rotation, the hydraulic oil tank will not wobble because it is adsorbed to the bottom of the hydraulic oil tank. After the angle rotation is completed, the welding process on both sides of the hydraulic oil tank can be realized. The welding area is more comprehensive, and no manual intervention is required throughout the process. It is only necessary to initially place the hydraulic oil tank on several limit blocks 26 for positioning.

[0041] Compared to existing technologies, this device can automatically and stably clamp and rotate the hydraulic oil tank to achieve omnidirectional welding operations. All external surfaces and interior surfaces of the hydraulic oil tank can be machined without obstruction, further improving welding efficiency.

[0042] In some embodiments, a six-degree-of-freedom robotic arm is provided on one side of the processing table 1, and a welding device is provided on the six-degree-of-freedom robotic arm; the six-degree-of-freedom robotic arm and the welding device are not shown in the figure, and the welding device is specifically a welding gun; in this embodiment, the welding device can be driven to move by the six-degree-of-freedom robotic arm and can be clamped and rotated by the hydraulic oil tank to achieve all-round automatic welding, without the need for manual operation of the welding gun, and the degree of automation is further improved.
