Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil tank processing, in particular to an automatic grinding device for a hydraulic oil tank weld. Background Art

[0002] The hydraulic oil tank is a container used to store the oil required to ensure the operation of the hydraulic system. The main functions of the hydraulic oil tank in the hydraulic system are: storing the oil required for system circulation; dissipating the heat generated when the system is working; releasing the gas mixed in the oil; providing a location for the installation of components in the system. When the construction machinery equipment is working, driven by the hydraulic pump, the hydraulic oil flows out from the oil suction port of the hydraulic oil tank and drives the hydraulic components such as the cylinder and motor through the hydraulic oil circuit. The returned hydraulic oil returns to the hydraulic oil tank through the oil return port of the hydraulic oil tank. The hydraulic oil tank is welded from multiple plates. After welding, the weld needs to be polished to make the weld smooth and free of protrusions.

[0003] During the existing grinding, one hand is used to support the hydraulic oil tank, and the other hand is used to hold the grinder to grind the weld. Both hands are doing two tasks at the same time, which is inconvenient to control and has certain risks. In addition, when turning over the frame, the grinder needs to be placed aside first, and then the frame is turned over, which reduces the work efficiency. If the frame is turned over by the handheld grinder, the risk of work will be increased.

[0004] Announcement No. CN217750752U proposes a box weld grinding device for distribution box processing. The device can grind different surfaces of the square frame. At this time, there is no need to manually hold a grinder to grind the weld, and it is far away from the grinding area, which not only improves work efficiency but also ensures the safety of workers during grinding. However, the device lacks a debris collection mechanism during the grinding process. At this time, a large amount of debris will accumulate on the placement plate and interfere with the subsequent placement of workpieces. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology, and then proposes an automatic grinding device for the weld of a hydraulic oil tank.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0008] This device can realize automatic grinding of the weld seam on the surface of the hydraulic oil tank and achieve stable adsorption during the grinding process. At the same time, it can effectively absorb and collect the debris generated during the grinding process, effectively reducing the probability of debris accumulating on the placement plate in the comparison file and thus interfering with the subsequent placement. The hydraulic oil tank weld seam grinding has a high degree of automation and significantly reduces the labor intensity of manual intervention.

[0009] Furthermore, the grinding assembly includes a grinding motor and a grinding disc. The three-axis device is provided with a grinding motor, the grinding motor is connected to the grinding disc and a suction pipe is provided on the grinding motor.

The fixed frame is provided with a long hole and an electric push rod. The electric push rod is connected to the electric cylinder. The retraction rod of the electric cylinder passes through the long hole and is connected to the servo motor. The servo motor is connected to the second electromagnetic plate.

[0012] The above scheme realizes the adsorption and flipping of the hydraulic oil tank through the deflection component, and at the same time, it is not hindered during the flipping process, so as to grind the welds on the upper and lower surfaces of the hydraulic oil tank.

[0013] Furthermore, a second collecting box is arranged on the mounting platform, and a side door is arranged on the second collecting box and connected to a collecting channel. The collecting channel is arranged obliquely and one end is spaced apart from the placing roller, and a collecting hole is opened on the collecting channel.

[0014] The above scheme can collect a small amount of debris that falls during the grinding process through the collection holes on the collection channel and store them in the second collection box. Subsequently, the side door can be opened at regular intervals to clean the debris inside the second collection box, which has a better effect on collecting debris.

[0015] Furthermore, a vibration motor is provided on the collecting channel.

[0016] The above solution can make all the debris in the collection channel enter the second collection box for storage through the vibration motor.

[0017] Furthermore, one end of the suction pipe is connected to a suction hood.

[0018] The above solution can further expand the suction area of ​​the debris through the suction hood, and the debris collection effect is better.

[0019] Furthermore, a sealing door is rotatably connected to the first collection box and a filter screen is movably connected inside the first collection box.

[0020] In the above scheme, after the filter has been used for a period of time, the sealing door can be opened to clean or replace it. After the replacement, closing the sealing door can ensure the sealing effect inside the first collection box and thus will not affect the suction of debris.

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

[0022] This device can realize automatic grinding of the weld seam on the surface of the hydraulic oil tank and achieve stable adsorption during the grinding process. At the same time, it can effectively absorb and collect the debris generated during the grinding process, effectively reducing the probability of debris accumulating on the placement plate in the comparison file and thus interfering with the subsequent placement. The hydraulic oil tank weld seam grinding has a high degree of automation and significantly reduces the labor intensity of manual intervention. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Further refinement of the embodiment of the present utility model is as follows: Figure 4 As shown, a sealing door is rotatably connected to the first collecting box 51 and a filter screen 56 is movably connected inside the first collecting box 51. The sealing door is not numbered in the figure. When the filter screen 56 has been used for a period of time, the sealing door can be opened immediately for cleaning or replacement. After replacement, closing the sealing door can ensure the subsequent sealing effect inside the first collecting box 51 without affecting the suction of debris.

[0032] Further refinement of the embodiment of the present utility model is as follows: Figure 1 As shown, the grinding assembly includes a grinding motor 23 and a grinding disc 24 . The three-axis device 22 is provided with the grinding motor 23 . The grinding motor 23 is connected to the grinding disc 24 and a suction pipe 52 is provided on the grinding motor 23 .

[0033] The above embodiment scheme is further refined, such as Figure 1 As shown, one end of the suction pipe 52 is open and connected to a suction hood 54; the suction hood 54 can further expand the suction area of ​​the debris, and the debris collection effect is better.

[0034] Further refinement of the embodiment of the present utility model is as follows: Figure 1 and Figure 2As shown, the deflection assembly includes an electric push rod 32, an electric cylinder 33, a servo motor 34 and a second electromagnetic plate 35. The fixed frame 3 is provided with a long hole 31 and an electric push rod 32. The electric push rod 32 is connected to the electric cylinder 33. The retraction rod of the electric cylinder 33 passes through the long hole 31 and is connected to the servo motor 34. The servo motor 34 is connected to the second electromagnetic plate 35.

[0036] The workflow of this utility model:

[0037] First, a hydraulic oil tank is placed on the first electromagnetic plate 13. The size of the hydraulic oil tank is larger than the size of the placement roller 11 and the size of the placement roller 11 is equal to that of the first electromagnetic plate 13. When the hydraulic oil tank is placed stably and one side is kept parallel to the grinding component, the controller controls the first electromagnetic plate 13 to energize, and then the hydraulic oil tank is stably adsorbed. Then the controller controls the three-axis device 22 to work and drive the grinding component to complete the welding seam grinding on one side of the hydraulic oil tank. While grinding, the controller controls the negative pressure fan 55 to work. After the negative pressure fan 55 is turned on, it is turned on. The debris generated during the grinding process can be effectively sucked out through the hose 53, the suction pipe 52 and the suction hood 54. When the debris is sucked into the first collection box 51, the debris will adhere to its surface due to the presence of the filter screen 56, and will not cause damage to the negative pressure fan 55. When the grinding of one side of the hydraulic oil tank is completed, the controller controls the drive assembly 12 to work and realize the 90-degree rotation of the placement roller 11. At this time, the next adjacent side is kept parallel to the grinding assembly and the weld grinding is started. The above process is repeated in sequence to achieve The four sides of the hydraulic oil tank are now ground. After the weld grinding of the four sides of the hydraulic oil tank is completed, the controller immediately controls the electric cylinder 33 to work so that the second electromagnetic plate 35 is close to one of the sides. When the second electromagnetic plate 35 contacts the hydraulic oil tank, it is immediately energized. At this time, the first electromagnetic plate 13 is powered off, and the hydraulic oil tank can be adsorbed immediately. Then the controller controls the electric push rod 32 to rise so that the hydraulic oil tank is away from the placement roller 11. When the hydraulic oil tank rises to a preset height that does not affect the deflection, it stops, and then the servo motor 34 works to realize The hydraulic oil tank is now flipped so that the bottom surface is parallel to the grinding assembly, and then the bottom surface weld is ground. After the bottom surface is processed, the servo motor 34 drives the hydraulic oil tank to rotate 180 degrees as a whole, and then the top surface weld is ground, thereby completing the grinding of the outer surface of the hydraulic oil tank. After the grinding is completed, the controller controls the second electromagnetic plate 35 to cut off the power, and then the hydraulic oil tank can be replaced to restart a new round of weld grinding process. During the grinding process, the debris can be effectively sucked, thereby effectively reducing the probability of the debris splashing around and falling onto the processing platform;

[0038] Compared with the existing technology, the present device can realize automatic grinding of the welds on the surface of the hydraulic oil tank and stably adsorb during the grinding process. At the same time, it can effectively absorb and collect the debris generated during the grinding process, effectively reducing the probability of debris accumulating on the placement plate in the comparison document and thus interfering with subsequent placement. The hydraulic oil tank weld grinding has a high degree of automation, which significantly reduces the labor intensity of manual intervention.

[0040] As a further refinement of the above embodiment, a vibration motor is provided on the collection channel 43, which is not shown in the figure; the vibration motor can make all the debris in the collection channel 43 enter the second collection box 41 for storage.
