Description

Technical Field

[0001] The utility model relates to bending part processing equipment, in particular to a bending part height processing device. Background Art

[0002] The boom cylinder of key components such as aerial work vehicles and truck cranes mostly adopts a bent structure. In order to obtain better strength and meet the requirements of lightweight booms, high-strength structural steel above Q690 level is currently basically used, and the plate thickness is basically less than 8mm. This type of high-strength structural steel has large internal stress, and the dimensional accuracy of the plate after bending is unstable. However, the height dimension of the bent part needs to be controlled within the deviation range of ±1mm. The current high-strength structural steel internal stress, bending equipment and process level are difficult to meet this technical requirement.

[0003] In the prior art, the height dimensions of the bent parts are measured manually, and then the parts exceeding the tolerance requirements are manually polished to make the height of the bent parts meet the assembly requirements. However, manual measurement may result in measurement errors, and the tolerance requirements may still not be met after manual polishing. In addition, when the bent parts are long, manual measurement, marking and polishing take a long time. In addition, when an angle grinder is used manually, about one grinding disc is consumed for polishing one piece. The grinding intensity of high-strength structural steel is very high, and it is easy to rebound and damage the parent material. Utility Model Content

[0031] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation modes described herein are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the specific implementation modes described below.

[0032] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "formed", "provided with", "set", "connected" and the like should be understood in a broad sense. For example, the connection can be a direct connection or an indirect connection through an intermediate medium, a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate connection member, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] In the present utility model, in the absence of corresponding explanations, the directions or positional relationships indicated by the directional words "up", "down", "left", "right", "counterclockwise", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only used to facilitate the description of the present utility model and simplify the description, rather than to indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model; the directional terms of the present utility model should be understood in conjunction with the actual installation state.

[0034] The utility model provides a bending part height processing device, see Figure 1-6 As a specific embodiment of the bending part height processing device of the utility model, it includes a workbench 1, a lifting mechanism 2, a centering clamping mechanism 3, a processing mechanism 4 and a three-way moving mechanism 5. The workbench 1 is used to place a workpiece 8 to be processed. The lifting mechanism 2 and the centering clamping mechanism 3 are respectively installed on the workbench 1. When the workpiece 8 to be processed is placed, the lifting mechanism 2 located below the workpiece 8 to be processed can lift the workpiece 8 to be processed to adjust the Z-direction height of the workpiece 8 to be processed. After the Z-direction height adjustment is completed, the workpiece 8 to be processed is centered and clamped by the centering clamping mechanism 3. After the positioning and clamping is completed, the processing mechanism 4 is moved in the X, Y and Z directions by the three-way moving mechanism 5, so that the processing mechanism 4 can be moved to the processing part of the workpiece 8 to be processed, and the lifting height of the lifting mechanism 2 is matched, so that the processing height of the processing mechanism is the design height of the workpiece 8 to be processed, so that the part of the workpiece 8 (boom bending part) to be processed in the height direction is processed by the lifting mechanism 2 to ensure that it meets the tolerance requirements of the height dimension, and the bending part height processing device of the utility model is fully automated, without the need for manual participation, ensuring the accuracy requirements while saving time and efficiency, greatly improving production efficiency. Among them, the tolerance is the allowable variation of the actual parameter value, for example, the upper and lower limits of the height dimension of the boom bending part are A and B, then the tolerance is the absolute value of the algebraic difference between A and B, and meeting the tolerance requirements of the height dimension means that the actual height dimension measured by the boom bending part is between A and B.

[0035] It should be noted that the height of the above-mentioned bending part is the dimension perpendicular to the horizontal direction when the workpiece is placed flat on a horizontal plane; see Figure 1 The X direction is the length direction of the workbench 1, the Z direction is the vertical direction, and the Y direction is the direction perpendicular to the X direction and the Z direction.

[0036] As a specific embodiment of the three-way moving mechanism 5, see Figure 1 and Figure 2The three-way moving mechanism 5 includes a gantry 501, an X-axis driving assembly 502, a Y-axis driving assembly 503 and a Z-axis driving assembly 504. The two vertical poles of the gantry 501 are movably installed on the Y-axis sides of the workbench 1 through the X-axis driving assembly 502. Specifically, the X-axis driving assembly 502 can adopt a screw transmission assembly, so that the X-axis moving distance of the gantry 501 can be accurately controlled by a servo motor. The processing mechanism 4 is movably installed on the cross bar of the gantry 501 through the Y-axis driving assembly 503 and the Z-axis driving assembly 504, so that the Y-axis movement and Z-axis movement adjustment of the processing mechanism 4 can be performed.

[0037] Further, see Figure 1 and Figure 2 After being bent, the arm bending part presents a semi-enclosed structure, which has two bending vertical plates respectively located on both sides. In order to improve the processing efficiency, two processing mechanisms 4 are arranged on the gantry 501. The Y-direction driving assembly 503 includes a Y-direction guide rail 503-1, a Y-direction slide 503-2 and a Y-direction driving member 503-3. The Y-direction guide rail 503-1 is installed on the cross bar of the gantry 501 along the Y direction, and the Y-direction guide rail 503-1 is slidably provided with two Y-direction slides 503-2. The Y-direction driving member 503-3 can drive the Y-direction slide 503-2 to move on the Y-direction guide rail 503-1. The two processing mechanisms 4 are movably installed on the two Y-direction slides 503-2 through the Z-direction driving assembly 504 respectively. The Y-direction driving member 503-3 includes a screw, a screw nut and a servo motor, so that the servo motor is controlled to drive the two processing mechanisms 4 to perform Y-direction Height adjustment, and Y-direction driving parts 503-3 can be respectively set corresponding to the two Y-direction slides 503-2, so as to be able to independently control the Y-direction movement of the processing mechanism 4; or, because the bending vertical plates on both sides of the arm bending part are symmetrically arranged after the centering clamping mechanism 3, correspondingly, the two processing mechanisms 4 are symmetrically arranged along the centering plane of the centering clamping mechanism 3, and the centering plane is the symmetrical center plane of the workpiece 8 to be processed after centering and positioning. In this case, it is preferred to set only one Y-direction driving part 503-3, and the two ends of the screw rod are respectively sleeved with screw nuts, and the two ends of the screw nut have opposite thread rotation directions, so that when the servo motor rotates, the screw nuts at both ends drive the two Y-direction slides 503-2 to move relative or oppositely, and then drive the two processing mechanisms 4 to be above the bending vertical plates on both sides of the workpiece 8 (arm bending part) to be processed. The above-mentioned Z-direction driving component preferably adopts a screw transmission component, so that the Z-direction movement distance of the processing mechanism 4 can be accurately controlled by the servo motor.

[0038] As a specific implementation of the centering clamping mechanism 3, see Figure 1 , Figure 3 and Figure 4The workbench 1 is provided with a plurality of centering clamping mechanisms 3 along the X direction. When the length of the workpiece 8 to be processed is relatively long, the centering positioning and clamping effect can be ensured. The centering clamping mechanism 3 comprises a fixed clamping plate 301, a movable clamping plate 302, a centering guide rail 303 and a centering driving member 304. The fixed clamping plate 301 is installed on the workbench 1, the centering guide rail 303 is installed on the workbench 1 along the Y direction, and the movable clamping plate 302 can be slidably installed on the centering guide rail 303. Specifically, the centering driving member 304 is a telescopic rod (electric telescopic rod, hydraulic telescopic rod, pneumatic telescopic rod), which is fixed on the workbench 1, and its telescopic end is connected to the movable clamping plate 302, so as to be able to drive the movable clamping plate 302 to move on the centering guide rail 303, so as to cooperate with the fixed clamping plate 301 for centering movement.

[0039] After the centering clamping mechanism 3 positions and clamps the workpiece 8 to be processed, in order to prevent the workpiece 8 to be processed from shaking during processing and ensure the processing effect of the height dimension, preferably, the clamping parts of the fixed clamping plate 301 and the movable clamping plate 302 are both provided with an electromagnetic suction cup 6, so that after positioning and clamping, the electromagnetic suction cup 6 can be energized to generate magnetic attraction, so as to firmly fix the workpiece 8 to be processed between the fixed clamping plate 301 and the movable clamping plate 302.

[0040] Furthermore, the electromagnetic suction cups 6 on the same side of the multiple centering clamping mechanisms 3 are arranged in sequence without intervals, so that the electromagnetic suction cups 6 on the same side form a continuous whole, thereby improving the adsorption effect on the workpiece 8 to be processed.

[0041] As a specific implementation of the lifting mechanism 2, see Figure 1 , Figure 3 , Figure 5 and Figure 6 The workbench 1 is provided with a plurality of lifting mechanisms 2 along the X direction. When the length of the workpiece 8 to be processed is long, the Z direction height of the workpiece 8 to be processed can be lifted as a whole. The lifting mechanisms 2 include a lifting mounting frame 201, a lifting platform 202, a lifting guide rail 203 and a lifting driving member 204. The lifting mounting frame 201 is installed on the workbench 1, the lifting guide rail 203 is installed on the lifting mounting frame 201 along the Z direction, the lifting platform 202 can be slidably installed on the lifting guide rail 203, and the lifting driving member 204 can drive the lifting platform 202 to move on the lifting guide rail 203 to adjust the Z direction height of the workpiece 8 to be processed.

[0042] Furthermore, the lifting drive component 204 includes a lifting screw 204-1, a lifting screw nut 204-2 and a lifting drive motor 204-3. One end of the lifting screw 204-1 is installed on the lifting mounting frame 201, and the other end is equipped with a lifting screw nut 204-2. The lifting platform 202 is connected to the lifting screw nut 204-2. The lifting drive motor 204-3 can drive the lifting screw 204-1 to rotate, so that the lifting screw nut 204-2 drives the lifting platform 202 to move along the Z direction.

[0043] As a specific embodiment of the present invention, the bending part height processing device also includes a conveying mechanism, see Figure 1-5 The conveying mechanism includes a plurality of conveying rollers 7 arranged at intervals along the X direction. The plurality of conveying rollers 7 are arranged below the centering plane of the centering clamping mechanism 3 to convey the workpiece 8 to be processed along the X direction, and the two ends of the conveying mechanism can be set corresponding to different workstations. For example, the conveying mechanism is set corresponding to the bending workstation, so that after the arm bending is completed, the arm bending part can be automatically conveyed to the workbench 1 through the conveying mechanism to perform height dimensional processing control and achieve automation. It should be noted that the conveying rollers 7 should be arranged at intervals and staggered with the lifting mechanism 2 to avoid interference between the lifting mechanism 2 and the conveying rollers 7 during the lifting process.

[0044] As a specific implementation of the present invention, see Figure 1 and Figure 6 The processing mechanism 4 can use a milling mechanism to perform milling on the upper plane of the arm support bending part to mill the part that exceeds the height dimension, and the processed surface is relatively smooth; and when there is no requirement for the oxide layer or roughness of the processed surface, the processing mechanism 4 can also use a laser head or a flame gun to cut the part that exceeds the height dimension. The above-mentioned milling mechanism, laser head and flame gun are well-known equipment to those skilled in the art and will not be described here.

[0045] In order to better understand the bending part height processing device of the present invention, the working process of the present invention is described below in combination with the above-mentioned relatively preferred technical features.

[0046] See also Figure 1-6First, the Z-direction height of the lifting platform 202 is made lower than the conveying height of the conveying roller 7, and the arm bending part is conveyed to between the fixed clamping plate 301 and the movable clamping plate 302 through the conveying roller 7. When the arm bending part is conveyed to a suitable X-direction position, the conveying roller 7 is stopped to complete the preliminary positioning; according to the size information of the bent part to be processed, the numerical parameters are input into the controller, and the controller can preferably be a PLC controller. The controller controls the rotation of the lifting drive motor 204-3 according to the input numerical parameters, and drives each lifting platform 202 to rise synchronously, so as to lift the arm bending part to the required Z-direction height Z1; then, the controller controls the centering drive member 304 to operate, and drives the movable clamping plate 302 to move in the center, so as to cooperate with the fixed clamping plate 301 to center and clamp the arm bending part; the controller controls the electromagnetic suction cup 6 to be energized to generate electricity Magnetic force is used to firmly adsorb the arm bending part to fix it and avoid shaking during processing that affects the processing accuracy; the controller controls the Y-axis driving component 503-3 to operate, so that the milling tools of the two milling mechanisms symmetrically arranged in the Y direction are located above the surfaces to be processed on both sides of the arm bending part; the controller controls the Z-axis driving component 504 to operate, and lowers the milling tool to a specified Z-axis height Z2, wherein the Z-axis height difference between Z2 and Z1 is the designed height dimension of the arm bending part, and the controller then controls the X-axis driving component 502 to operate, and synchronously controls the rotation of the milling tool to move the milling tool from one end of the arm bending part to the other end, thereby milling the upper end surfaces of the folding plate vertical plates on both sides of the arm bending part, milling off the parts that exceed the height dimension requirements, and can also cooperate with the three-way moving mechanism 5 to process straight edges, downslopes and upper chamfers for deburring.

[0047] The bending part height processing device of the utility model avoids tedious manual measurement, and does not need to use an angle grinder to grind the height of the bending part, which greatly reduces the accuracy of manual labor; through the automated control of each mechanism, it ensures that the height size of the boom bending part is met, ensures the accuracy requirement while saving time and efficiency, and greatly improves production efficiency; and it can adapt to the processing needs of different types of boom bending parts by adjusting the operating parameters of each mechanism.

However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0049] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
