Description

Technical Field

[0001] The present invention belongs to the technical field of parts cutting, and in particular relates to a parts cutting device for manufacturing new energy vehicles. Background Art

[0002] Large gears are required in the transmission structure of new energy vehicles. During the processing of large gears, circular holes need to be cut on them. Cutting circular holes can reduce the weight of the gears, facilitate gear lifting and assembly, reduce deformation during heat treatment, block and isolate vibrations, and reduce noise, thereby improving the performance, service life, work efficiency and safety of the gears.

[0003] The circular hole cutting design of the gear needs to consider the hole diameter, position accuracy and matching requirements. During the design, it is necessary to ensure that the size and position of the hole meet the use requirements. During the processing, the size, tolerance and surface roughness of the hole need to be strictly controlled to ensure that the gear can work properly.

[0004] During the laser cutting process of circular holes in large gears, since the number of circular holes cut in large gears of different sizes is different, the large gear is rotated by a certain angle after cutting a circular hole, and then cut by cutting equipment. When current cutting equipment is used, the rotation angle of the large gear cannot be accurately adjusted during cutting, which may result in inaccurate cutting or failure to meet the processing requirements of gears of different sizes. In addition, the waste generated during the cutting process may adhere to the inside of the circular hole of the large gear, causing waste accumulation and affecting the cutting quality. Secondly, it is necessary to enable the equipment to meet the automatic cutting processing of large gears of various specifications. In response to the above problems, the inventors proposed a cutting device for processing new energy vehicle parts to solve the above problems. Summary of the Invention

[0005] The present invention addresses the problems of the prior art and adopts a technical solution as follows: a parts cutting device for new energy vehicle manufacturing, comprising: a processing table, an electric cutter, a limit plate, a pump, and a collection frame; the electric cutter is installed at the front of the processing table; the limit plate is detachably connected to the front of the processing table; the limit plate is located above the electric cutter; the pump is installed on the limit plate; the collection frame is provided at the bottom of the processing table; the collection frame is located behind the electric cutter; The electric cutter includes a first electric actuator, a limit member, a filling member, an air pipe, a filter and a support member; two first electric actuators distributed on the left and right are installed in front of the processing table; the first electric actuator is an electric push rod; all the telescopic parts of the first electric actuator are fixed to the limit plate; all the first electric actuators are located in the limit plate; the limit member is welded on the top of the limit plate; two arc-shaped limit grooves distributed on the left and right are provided on the limit member; a dust collecting chamber is opened inside the limit member; a plurality of ventilation holes are opened in the front of the dust collecting chamber, among which the number of ventilation holes at the edges of the arc-shaped limit grooves on the dust collecting chamber is greater and denser; two filling members distributed on the left and right are connected to the lower part of the limit member; the filling member is an air bag; an air pipe is welded in the dust collecting chamber; a plurality of ventilation holes are opened in the front of the air pipe, and the ventilation holes are connected to the dust collecting chamber; the upper part of the air pipe is connected to the input end of the pump; a filter is detachably connected to the dust collecting chamber; the filter is located in front of the air pipe; two support members distributed on the left and right are provided in front of the limit member.

[0006] First, the two first electric actuators are controlled to start, and the two first electric actuators extend, synchronously driving the limit plate, the limit piece and the filler piece to move upward. Then the operator controls the manipulator to transfer the two workpieces to be processed to the processing table and place the two workpieces to be processed side by side. Then the manipulator is controlled to push the workpieces to be processed forward so that the front of the workpieces to be processed extends under the limit piece, and according to the set processing thickness of the required automotive parts, the front of the workpieces to be processed is extended into the cutting area. Then the limit piece is controlled to reset, and then air is inflated into the filler piece, so that the filler piece expands and fits tightly with the outer surface of the workpiece to be processed, thereby achieving a full-dimensional flexible wrapping fixation of the periphery of the workpiece to be processed. At the same time, by inserting a support piece into the workpiece to be processed, the support piece supports the inside of the workpiece to be processed, effectively preventing the workpiece from being deformed during the cutting process due to the curved thin wall on the upper part of the cutting piece, thereby jamming the electric cutter, hindering the processing of the workpiece to be processed, and easily causing damage to the electric cutter.

[0007] At the same time, the entire cutting area is covered by the limit plate, so that the debris and dust generated by the electric cutter cutting the workpiece are blocked by the limit plate, effectively avoiding the dispersion of dust. At the same time, the pump is controlled to start, and the pump draws the air in the limit part through the air pipe. The limit part draws the air in the limit plate into the limit part through the vent hole at the front. The debris and dust in the limit plate enters the limit part with the air, and then the dust and debris are intercepted by the filter element, realizing the collection of dust in the process of automobile parts processing. The ventilation holes near the arc-shaped limit groove of the positioning part are relatively dense. Therefore, when the electric cutter cuts the workpiece to be processed, a large amount of heat is generated, which is also quickly drawn into the limiting part along with the air through the dense ventilation holes around the arc-shaped limit groove, so that the electric cutter at the cutting position is quickly cooled down to avoid overheating of the electric cutter, which causes the temperature of the workpiece to be processed to be too high. During the processing of the workpiece to be processed, the thin-walled position or the curved surface position is prone to deformation, so that the electric cutter is stuck by the deformed workpiece to be processed, affecting the processing process of automotive parts and reducing production efficiency.

[0008] Compared with the prior art, the advantages and positive effects of the present invention are: The present invention provides a parts cutting device for new energy vehicle manufacturing, comprising: a processing table, an electric cutter, a limiting plate, a pump and a collection frame; the front of the processing table is equipped with an electric cutter; the front of the processing table is detachably connected to the limiting plate; the limiting plate is located above the electric cutter; the pump is installed on the limiting plate; the lower part of the processing table is provided with a collection frame; the collection frame is located behind the electric cutter, and the entire cutting area is limited by the limiting plate, and then the dust and debris are collected by the limiting member to avoid dust diffusion and pollution of the environment, wherein the vent holes near the arc-shaped limiting groove of the limiting member are relatively dense, so as to achieve The cutting position and the electric cutter cool down quickly to avoid deformation of thin-walled positions or curved surfaces. At the same time, by inserting support members into the workpiece to be processed, the support members support the thin walls of the workpiece to be processed to avoid deformation of the cut thin-sheet cutting piece, which causes the electric cutter to be stuck by the deformed workpiece to be processed, affecting the processing process of automotive parts and reducing production efficiency. When the equipment is cutting, the rotation angle of large gears can be accurately adjusted, and the waste generated during the cutting process can be removed in time to improve the cutting quality. Secondly, the equipment can meet the automatic cutting processing of large gears of various specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Example 1, as Figures 1 to 3 As shown, the present application provides a parts cutting device for new energy vehicle manufacturing, comprising: a processing table 1, an electric cutter 2, a limit plate 3, a pump 4 and a collection frame 5; the electric cutter 2 is installed at the front of the processing table 1; the limit plate 3 is detachably connected to the front of the processing table 1; the limit plate 3 is located above the electric cutter 2; the pump 4 is installed on the limit plate 3; the collection frame 5 is provided at the bottom of the processing table 1; the collection frame 5 is located behind the electric cutter 2; The electric cutter 2 includes a first electric actuator 41, a limiter 31, a filling member 32, an air pipe, a filter and a support member 42; two first electric actuators 41 are installed on the front of the processing table 1, which are distributed on the left and right; the first electric actuators 41 are electric push rods; the telescopic parts of all the first electric actuators 41 are fixed to the limit plate 3; all the first electric actuators 41 are located in the limit plate 3; the limiter 31 is welded on the top of the limit plate 3; the limiter 31 is provided with two arc-shaped limit grooves distributed on the left and right; the limiter 31 is provided with a collection groove Dust chamber; a plurality of ventilation holes are opened at the front of the dust collecting chamber, among which the number of ventilation holes at the edge of the arc-shaped limit groove on the dust collecting chamber is larger and denser; the lower part of the limit member 31 is connected to two filling members 32 distributed on the left and right; the filling member 32 is an air bag; an air pipe is welded in the dust collecting chamber; a plurality of ventilation holes are opened at the front of the air pipe, and the ventilation holes are connected to the dust collecting chamber; the upper part of the air pipe is connected to the input end of the pump 4; a filter is detachably connected to the dust collecting chamber; the filter is located in front of the air pipe; two support members 42 distributed on the left and right are provided in front of the limit member 31.

[0014] First, the two first electric actuators 41 are controlled to start, and the two first electric actuators 41 extend, synchronously driving the limit plate 3, the limit member 31 and the filling member 32 to move upward. Then, the operator controls the manipulator to transfer the two workpieces to be processed to the processing table 1 and place the two workpieces to be processed side by side. Then, the operator controls the manipulator to push the workpieces to be processed forward so that the front of the workpieces to be processed extends under the limit member 31. According to the set processing thickness of the automotive parts, the front of the workpieces to be processed extends into the cutting area. Then, the limit member 31 is controlled to reset. Then, air is inflated into the filling piece 32 to make the filling piece 32 expand and fit tightly against the outer surface of the workpiece to be processed, thereby achieving all-round flexible wrapping and fixation of the periphery of the workpiece to be processed. At the same time, the support piece 42 is inserted into the workpiece to be processed so that the support piece 42 supports the inside of the workpiece to be processed, effectively preventing the workpiece from being easily deformed during the cutting process due to the curved thin wall on the upper part of the cutting piece during the cutting process, thereby jamming the electric cutter 2, hindering the processing of the workpiece to be processed, and easily causing damage to the electric cutter 2.

[0015] At the same time, the entire cutting area is covered by the limit plate 3, so that the debris dust generated by the electric cutter 2 cutting the workpiece is blocked by the limit plate 3, effectively preventing the dispersion of dust. At the same time, the pump 4 is controlled to start, and the pump 4 draws the air in the limit member 31 through the air pipe. The limit member 31 draws the air in the limit plate 3 into the limit member 31 through the air vent at the front. The debris dust in the limit plate 3 enters the limit member 31 with the air, and then the dust debris is intercepted by the filter element, thereby realizing the collection of dust in the process of automobile parts processing. The ventilation holes near the arc-shaped limiting groove of the limiting member 31 are relatively dense. Therefore, when the electric cutter 2 cuts the workpiece, a large amount of heat generated is also quickly drawn into the limiting member 31 along with the air through the dense ventilation holes around the arc-shaped limiting groove, so that the electric cutter 2 at the cutting position is quickly cooled down, avoiding overheating of the electric cutter 2, which causes the temperature of the workpiece to be processed to be too high. During the processing of the workpiece, the thin-walled position or the curved surface position is prone to deformation, so that the electric cutter 2 is stuck by the deformed workpiece, affecting the processing process of automobile parts and reducing production efficiency.
