[0002] A hydraulic excavator breaker is a crushing tool installed on an excavator and is used to process hard materials such as concrete or rock. It generates a powerful impact force through a hydraulic system to crush these materials. The installation housing of the breaker is usually formed by cutting and welding a relatively thick steel plate, so as to ensure that the housing can work stably under high pressure and impact conditions.

[0003] When cutting the steel plate of the breaker housing, the steel plate needs to be placed on a conveying roller rack first. The motor drives the conveying rollers to rotate and drives the steel plate to move to a laser cutter. After the steel plate is limited and clamped by a limiting component, the laser cutter cuts the steel plate. After cutting is completed, the steel plate is unloaded and welded and assembled into the breaker housing. However, for the laser cutter in the related art, before each cutting of the steel plate, the limiting component needs to re-limit and clamp the steel plate. When the angle of the steel plate deflects greatly under the drive of the conveying rollers, the limiting component cannot correct the steel plate by means of limiting and clamping, and manual assistance is required, and then the limiting component is controlled to clamp the steel plate, thus affecting the cutting efficiency of the housing of the hydraulic excavator breaker.

The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0020] The cutting device for the housing of a hydraulic excavator breaker according to an embodiment of the present invention will be described below with reference to the drawings.

[0021] As Figures 1-3 shown, the cutting device for the housing of a hydraulic excavator breaker according to an embodiment of the present invention may include a conveyor assembly 1, a cutting assembly 2, a sliding member 3, a linkage assembly 4, an electric telescopic rod 5 and a limiting member 6.

[0022] Among them, the conveyor assembly 1 may include a conveyor support 10, a plurality of conveyor rollers 11 and a driving mechanism 12. Among them, the plurality of conveyor rollers 11 are respectively rotatably arranged on the conveyor support 10, and the driving mechanism 12 is rotatably arranged on the conveyor support 10 and is connected to the corresponding conveyor roller 11.

[0023] It should be noted that the driving mechanism 12 described in this embodiment is a common driving mechanism 12 in the roller conveyor assembly 1 on the market, which includes a motor, a plurality of transmission shafts, a plurality of transmission belts, a plurality of transmission rollers. The motor is connected to one of the conveyor rollers 11, the transmission shafts are respectively connected to the corresponding conveyor rollers 11, the transmission belts are respectively sleeved on the corresponding transmission rollers, and the transmission rollers are respectively arranged on the corresponding transmission shafts, so that a single motor can drive the rotation of the plurality of conveyor rollers 11.

[0024] The cutting assembly 2 is arranged on the support plate 100 arranged on the conveyor support 10.

[0025] In the embodiment of the present application, the cutting assembly 2 is used to cut the steel plate.

[0026] The sliding members 3 are respectively arranged on the conveyor support 10.

[0027] In the embodiment of the present application, when the electric telescopic rod 5 extends to control the limiting member 6 to clamp the steel plate, the sliding member 3 is used to control the parallel movement of the electric telescopic rod 5 and the limiting plate 60 on the conveying bracket 10, so as to realize the continuous limiting clamping of the steel plate during the cutting process without manual correction of the steel plate.

[0028] One end of the linkage assembly 4 is respectively connected to the corresponding conveying roller 11, and the other end of the linkage assembly 4 is arranged on the corresponding sliding member 3.

[0029] In the embodiment of the present application, the linkage assembly 4 is used to convert the rotation of the conveying roller 11 into the translational sliding of the sliding member 3, so as to realize the sliding of the steel plate in the limited state, reduce the use of relevant electric driving devices, and reduce the use cost of the device.

[0030] The electric telescopic rods 5 are respectively arranged on the sliding members 3.

[0031] It can be understood that through the setting of the electric telescopic rod 5, when the electric telescopic rod 5 extends, it can control the limiting plate 60 to limit and clamp the steel plate, and make it perform limiting clamping on the conveying assembly 1, so as to ensure the cutting quality of the steel plate.

[0032] The limiting member 6 may include a limiting plate 60 and a linkage telescopic plate 61.

[0033] Among them, the limiting plates 60 are respectively arranged on the extending shafts of the electric telescopic rods 5, and the end parts of the linkage telescopic plates 61 are respectively connected to the limiting plates 60.

[0034] In the embodiment of the present application, the limiting plate 60 is used to abut against both sides of the steel plate, so as to limit and clamp the steel plate.

[0035] It can be understood that through the setting of the linkage telescopic plate 61, when the electric telescopic rod 5 extends, the linkage telescopic plate 61 can contract, so that the limiting plate 60 can clamp and limit the steel plate. When the sliding member 3 drives the electric telescopic rod 5 and a limiting plate 60 to move, one limiting plate 60 can drive the other limiting plate 60 through the linkage telescopic plate 61, so as to ensure the sliding effect of the steel plate on the conveying assembly 1.

[0036] Specifically, during the actual operation, the relevant staff place the steel plate on the conveying support 10 and inside the limiting plate 60 and the linkage telescopic plate 61. Then, this device is started, and the controller (not shown in the figure) controls the electric telescopic rod 5 to extend, driving the two limiting plates 60 to tightly abut against both sides of the steel plate respectively, thereby limiting and clamping the steel plate. The controller controls the driving mechanism 12 to do work, and the driving mechanism 12 controls the rotation of multiple conveying rollers 11. The rotation of the conveying rollers 11 drives the rotation of the linkage assembly 4, and the linkage assembly 4 controls the sliding member 3 to slide on the conveying support 10, so as to perform synchronous parallel movement with the steel plate. After the steel plate moves to the cutting position of the cutting assembly 2, the driving mechanism 12 stops rotating, and the cutting assembly 2 cuts the steel plate. After the cutting is completed, the driving mechanism 12 continues to do work and repeats the above operations. Therefore, it is only necessary to perform single clamping and limiting on the steel plate, and there is no need to manually correct the steel plate with a large deflection angle and then perform limiting clamping and cutting, thereby improving the cutting efficiency of the hydraulic excavator breaker housing.

[0037] In an embodiment of the present invention, as Figures 1-3 shown, the linkage telescopic plate 61 may include a first connecting plate 610, a second connecting plate 611, and a connecting column 612.

[0038] Wherein, one end of the first connecting plate 610 is connected to one limiting plate 60, the other end of the first connecting plate 610 is slidably inserted into the connecting column 612, one end of the second connecting plate 611 is connected to the other limiting plate 60, and the other end of the second connecting plate 611 is slidably inserted into the connecting column 612.

[0039] It should be noted that when the connecting column 612 expands and contracts in the first connecting plate 610 and the second connecting plate 611 in this embodiment, it will not fall off from the inserted and sliding states with the first connecting plate 610 and the second connecting plate 611, thereby ensuring the sliding effect of the second connecting plate 611 driving the first connecting plate 610.

[0040] In an embodiment of the present invention, as Figures 1-3 shown, the linkage assembly 4 may include a plurality of gears 40 and a toothed plate 41.

[0041] Wherein, the plurality of gears 40 are respectively connected to the corresponding conveying rollers 11, the gears 40 are respectively intermittently meshed and connected to the toothed plate 41, and the toothed plate 41 is arranged on the corresponding sliding member 3.

[0042] It should be noted that the toothed plate 41 can be meshed and connected with two or more gears 40 simultaneously, so that after a single gear 40 completes driving the gear 40, another gear 40 is meshed with the toothed plate 41 in a relay manner, thereby ensuring the rotation control effect of the gear 40 on the toothed plate 41.

[0043] In an embodiment of the present invention, asFigures 1-3 As shown, the sliding member 3 may include a sliding block 30 and a slide rail 31.

[0044] Among them, the slide rails 31 are respectively arranged on both sides of the conveying bracket 10, the sliding blocks 30 are respectively slidably connected to the corresponding slide rails 31, the toothed plate 41 is arranged on the corresponding sliding block 30, and the electric telescopic rods 5 are respectively arranged on one side of the sliding blocks 30.

[0045] It can be understood that through the arrangement of the slide rails 31, the sliding connection between the sliding blocks 30 and the conveying bracket 10 is realized.

[0046] In an embodiment of the present invention, as Figures 1-3 shown, the cutting assembly 2 may include a cutting bracket 20 and a laser cutter 21.

[0047] Among them, one end of the cutting bracket 20 is arranged on the support plate 100, the other end of the cutting bracket 20 is arranged on the conveying bracket 10, and the laser cutter 21 is slidably arranged on the cutting bracket 20.

[0048] It can be understood that through the arrangement that the laser cutter 21 is slidably arranged on the cutting bracket 20, the laser cutter 21 can perform sliding cutting on the steel plate, thereby ensuring the cutting effect of the steel plate.

[0049] Specifically, during the actual operation, the relevant staff place the steel plate on the conveying bracket 10 and inside the limiting plate 60 and the linkage telescopic plate 61, start the device, the controller (not shown in the figure) controls the electric telescopic rod 5 to extend, driving the two limiting plates 60 to respectively abut against both sides of the steel plate, thereby limiting and clamping the steel plate. The controller controls the driving mechanism 12 to do work, the driving mechanism 12 controls the rotation of the plurality of conveying rollers 11, the rotation of the conveying rollers 11 drives the gear 40 to rotate, the corresponding gear 40 meshes with the toothed plate 41, so that the sliding block 30 connected to the toothed plate 41 is slidably connected to the slide rail 31 and the conveying bracket 10, and thus moves in parallel synchronously with the steel plate. After the steel plate moves to the cutting position of the cutting assembly 2, the driving mechanism 12 stops rotating, and the laser cutter 21 performs sliding cutting on the steel plate. After the cutting is completed, the driving mechanism 12 continues to do work, repeating the above operations, so that it is only necessary to perform single clamping and limiting on the steel plate, and there is no need to manually correct the steel plate with a large deflection angle and then perform limiting clamping and cutting, thereby improving the cutting efficiency of the hydraulic excavator breaker housing.

[0050] In summary, for the cutting device of the hydraulic excavator breaker housing in the embodiment of the present invention, only single clamping of the steel plate of the breaker housing is required to achieve continuous clamping and limiting of the steel plate, and there is no need to manually correct the steel plate, thereby improving the cutting efficiency of the hydraulic excavator breaker housing.
