Description

Technical Field

[0001] This invention relates to the field of milling equipment, and more particularly to a milling device for a weight-reducing groove in an integrated electrical cabinet base and an electrical cabinet. Background Technology

[0002] Electrical cabinet bases are typically made of sheet metal. To reduce overall weight while maintaining structural strength, multiple weight-reducing grooves are usually milled on the base surface. Current methods for machining these grooves often employ gantry milling machines or CNC machining centers. During milling, as the grooves gradually form, the remaining thickness of the workpiece decreases, causing changes in stiffness across different areas. This can lead to localized vibrations and deformations, affecting the dimensional accuracy and flatness of the groove bottom. Furthermore, the large amount of metal debris generated during milling can easily scatter or accumulate in the machining area, leading to secondary cutting of the debris, impacting machining quality, and increasing subsequent cleaning workload. Therefore, improving the local support stability of the workpiece during the machining process of the weight-reducing grooves, and achieving timely restriction and centralized collection of machining debris, has become a pressing technical problem for those skilled in the art. Therefore, we propose an integrated electrical cabinet base weight-reducing groove milling device and electrical cabinet to address the aforementioned problems. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention uses a support frame and a bottom chamber located on the upper and lower sides of the milling cutter, respectively, to form corresponding local constraint areas in the processing area. The support frame is always located directly below the milling cutter to provide support, while the bottom chamber and pressure bar are always located above the processing area to restrict movement. This ensures that the area near the processing area is always under stable stress, effectively reducing vibration and warping caused by changes in local stiffness due to the continuous formation of weight-reducing grooves. It also improves the dimensional consistency, groove bottom flatness, and processing stability during the processing of multiple weight-reducing grooves.

[0016] 2. This invention forms multiple independent inner cavities by dividing the bottom compartment, and fills each cavity with electromagnetic fluid and sets up an excitation coil. At the same time, multiple electric push rods drive the corresponding pressure strips, so that the overall rigidity and clamping force of the bottom compartment can be adjusted in each area. Differentiated local constraints are formed according to the changes in the remaining thickness of different areas of the base, so that the bottom of the bottom compartment always maintains a good fit, reduces local stress concentration and clamping marks, and improves the processing quality of thin-walled areas and the overall processing stability.

[0017] 3. This invention uses a mounting frame to drive the suction plate to move synchronously with the milling cutter, so that the suction plate and the limiting component always form a local limiting space around the processing area. The negative pressure generated by the pump body is used to suck the debris into the collection bin in a timely manner, so that the generation, limiting and collection of debris are carried out simultaneously. This effectively reduces the scattering of debris and the accumulation of debris in the groove, avoids secondary cutting of debris and scratching of the groove bottom, improves the processing environment, reduces the amount of subsequent manual cleaning, and improves the efficiency of continuous processing.

[0026] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] like Figures 1-7The integrated electrical cabinet base weight-reducing groove milling device shown includes a frame 101 mounted on a mounting base. A ball screw is mounted on the inner top of the frame 101. A base frame 132 is mounted on the moving part of the ball screw. The base frame 132 is slidably connected to the middle of the top of the frame 101. A fixed platform 120 is mounted on the top of the base frame 132. Multiple vibration sensors are mounted on the top of the fixed platform 120 to detect the vibration of the base blank, facilitating subsequent adjustments. A uniformly distributed connecting frame 139 runs through the middle of the fixed platform 120. Connecting compartments 131 are fixedly connected to the front and rear of the connecting frame 139. The connecting compartments 131 are installed at the front and rear of the fixed platform 120. The top of the fixed platform 120 is provided with uniformly distributed adsorption holes 130, which all penetrate the top of the fixed platform 120 and the connecting frame 139. Vacuum pumps 138 are installed on the front and rear sides of the base frame 132. Multiple connecting pipes 128 are fixedly connected to the working ends of the vacuum pumps 138. The ends of the connecting pipes 128 away from the vacuum pumps 138 are connected to the interior of the connecting chamber 131. A set of bellows covers 111 are installed at the front and rear ends of the fixed platform 120. The ends of the bellows covers 111 away from the fixed platform 120 are respectively installed on the front and rear sides of the top of the frame 101. Multiple fixed anchor rods 102 are installed on both sides of the frame 101. The frame 101 is installed on the mounting base through the fixed anchor rods 102.

[0028] Furthermore, in specific implementation, before processing, the electrical cabinet base blank is laid flat on the top surface of the fixed table 120. After rough positioning, the vacuum pump 138 is started through the control panel 106. The vacuum pump 138 extracts air from the connecting chamber 131 and the connecting frame 139 to form a negative pressure chamber. The negative pressure acts on the bottom surface of the base through the densely distributed adsorption holes 130, firmly pressing the base onto the surface of the fixed table 120, preventing the base from slipping or shifting during the milling feed, and ensuring the positional accuracy of the weight reduction groove. When the base frame 132 moves longitudinally with the fixed table 120... During operation, the bellows cover 111 synchronously telescopically encloses the sliding gap at the top of the frame 101, isolating milling dust and cutting debris from entering the bottom ball screw transmission pair, preventing the screw from rusting and jamming, and extending the service life of the linear transmission components. Multiple sets of threaded mounting holes are reserved at the bottom of the frame 101, and the fixed anchor rods 102 are pre-embedded in the concrete base of the equipment. The top of the anchor rods is threaded and locked to the frame 101. During the milling operation of the whole machine, the fixed anchor rods 102 can offset the impact vibration generated by the high-speed cutting of the milling cutter 123, avoid the displacement of the whole machine, and ensure the continuous stability of vacuum adsorption positioning.

[0029] The mounting base is equipped with electric guide rails on both sides of the top. A vertical frame 105 is installed at the top of the moving part of the electric guide rail. A horizontal frame 107 is installed on the top of the vertical frame 105. A control panel 106 is installed on one side of the horizontal frame 107. The control panel 106 is used to control other electrical control equipment. An electric lead screw is installed in the middle of the front side of the horizontal frame 107. An electric lifting platform 108 is installed in the moving part in front of the electric lead screw. A fixed compartment 110 is installed in the moving part in front of the electric lifting platform 108. A drive motor 109 is installed in the middle of the front side of the electric lifting platform 108. The drive motor 109 is located in the middle of the upper side of the top of the fixed compartment 110. The bottom drive end of the drive motor 109 passes through the middle of the fixed compartment 110 and is equipped with a machine head 116. The drive motor 109 and the machine head 116 do not contact the fixed compartment 110. A milling cutter 123 is installed in the bottom of the machine head 116. Limiting component one and limiting component two are respectively located on the front and rear sides of the milling cutter 123.

[0030] Furthermore, in specific implementation, after the base is fixed by vacuum adsorption, the drive motor 109 is started through the control panel 106. The drive motor 109 drives the machine head 116 and the milling cutter 123 to rotate at high speed. Then, the electric lifting platform 108 feeds downward, driving the milling cutter 123 to contact the base plate and start the milling and grooving action. The electric lead screw on the cross frame 107 drives the entire machine head mechanism to move laterally. In conjunction with the ball screw inside the frame 101, it drives the base frame 132 and the base to feed longitudinally, realizing the X and Y axis linkage switching of the processing point and completing the continuous milling operation of the entire weight reduction groove. The limiting component 1 and the limiting component 2 are arranged on the front and rear sides of the milling cutter 123, and move synchronously with the milling cutter 123 to press the plate in the processing area in real time and suppress milling vibration.

[0031] The base frame 132 has a sliding groove 137 in the middle of both sides. The sliding groove 137 is slidably connected to a slide plate 140. The top of the slide plate 140 is fixedly connected to a uniformly distributed support frame 129. The top of the support frame 129 is slidably connected to the inside of the fixed platform 120. The two ends of the slide plate 140 are fixedly connected to a fixed frame 117. The end of the fixed frame 117 away from the slide plate 140 is fixedly connected to the frame 101. The side of the fixed frame 117 away from the fixed platform 120 is equipped with an electric lifting platform 118. The top moving part of the electric lifting platform 118 is slidably connected to the fixed frame 117. The top of the moving part of the electric lifting platform 118 is fixedly connected to a limit frame 115.

[0032] Furthermore, in specific implementation, the slide plate 140 is rigidly connected to the frame 101 via the fixed frame 117 and is a stationary component. When the base frame 132 moves longitudinally with the ball screw, the slide groove 137 slides relative to the slide plate 140, so that the support frame 129 always stays directly below the milling cutter 123, forming a continuous and complete support surface at the bottom of the base plate, avoiding the bottom of the base processing area from being suspended, eliminating resonance caused by uneven local stiffness of the plate, preventing vibration marks from appearing at the bottom of the groove after milling, and greatly improving the surface processing quality of the weight reduction groove. At the same time, the electric lifting platform 118 can raise / lower the limit frame 115 as a whole, adapting to bases of different thicknesses and adjusting the initial height of the top clamping component.

[0033] Among them, mounting brackets 126 are provided on the front and rear sides of the limiting brackets 115. Slider 121 is fixedly connected to the middle of the front and rear ends of the mounting brackets 126. Threaded rods 127 are threaded through and threaded to the middle of the sliders 121. Servo motors 113 are installed at the ends of the threaded rods 127. Servo motors 113 are installed at the middle of one end of the limiting brackets 115. Threaded sections are symmetrically arranged on both sides of the middle of the outer periphery of the threaded rods 127. Limiting component one and limiting component two are respectively installed on the inner side of the mounting brackets 126.

[0034] Furthermore, in specific implementation, when changing the weight-reducing groove of the electrical cabinet base with different specifications, the control panel 106 starts the servo motor 113 to drive the threaded rod 127 to rotate. The symmetrical positive and negative threads drive the sliders 121 on both sides to move closer together or separate in opposite directions, quickly adjusting the lateral spacing of the two sets of mounting brackets 126 to match the width of the base. After the spacing is adjusted, the self-locking nut locks the slider 121. During the processing, the two sets of limiting components simultaneously cover the front and rear processing areas of the milling cutter 123, forming a bidirectional constraint structure with the bottom support frame 129.

[0035] The limiting components one and two include a fixing plate one 124 and a fixing plate two 125, respectively. Both fixing plate one 124 and fixing plate two 125 are installed on the upper inner side of the mounting frame 126. The bottom of both fixing plate one 124 and fixing plate two 125 are fixedly connected with evenly distributed fixing strips 134. The bottom of each fixing strip 134 is equipped with evenly distributed electric push rods 136. The telescopic ends of each electric push rod 136 are equipped with pressure strips 135. The number of pressure strips 135 corresponds to the number of fixing strips 134 and they are respectively located directly below the fixing strips 134. The lower inner side of the mounting frame 126 is equipped with a bottom chamber 133. The bottom chamber 133 is divided into evenly distributed inner cavities. The inner cavities correspond to the pressure strips 135 and are filled with electromagnetic flux. Excitation coils are installed inside the inner cavities. The periphery and top of the bottom chamber 133 are made of rigid material and the bottom is made of flexible material. The bottom chamber 133 is located below the pressure strips 135.

[0036] Furthermore, in specific implementation, after the electric lifting platform 118 moves the limit frame 115 and the mounting frame 126 downward, the flexible bottom surface of the base 133 first fits the contour of the top surface of the base. During the processing, the milling cutter 123 continuously removes the plate material, and the remaining thickness of each area of ​​the base changes continuously: In areas with large remaining thickness of the base: the current of the corresponding inner cavity excitation coil is increased, the electromagnetic fluid is quickly solidified, the local rigidity of the base 133 is improved, and at the same time, the extension of the corresponding electric push rod 136 is increased, and the pressure bar 135 applies greater downward pressure to firmly constrain the thick plate area and suppress cutting vibration; In areas with thin remaining thickness of the base: the excitation current of the corresponding coil is reduced, the electromagnetic fluid is restored to flexibility, and the downward pressure of the electric push rod 136 is reduced simultaneously to avoid excessive local clamping force squeezing the thin plate and causing deformation; The flexible bottom surface of the base 133 fits the base surface throughout the process, and together with the support frame 129 below, it forms a stable constraint from top to bottom, reducing plate deformation and vibration, and ensuring that the weight reduction groove has uniform size and a flat bottom without ripples.

[0037] Among them, electric slide rails 103 are installed on the front center of the upright frame 105, and lifting frames 104 are installed on the front moving parts of the electric slide rails 103. Slide rods 114 are fixedly connected between the front and rear parts of the two lifting frames 104. The slide rods 114 pass through the front and rear parts of the suction plate 119 and are slidably connected to the suction plate 119. Suction components are installed in two parts inside the fixed silo 110. The suction components include pump bodies and collection bins. The pump bodies are installed on the upper parts of both sides inside the fixed silo 110. The collection bins are installed in two parts. The sliding connection is located on the lower part of both sides of the fixed chamber 110. The bottom of the fixed chamber 110 is equipped with connecting pipes 112 on both sides. The bottom of the connecting pipes 112 is fixedly connected to the suction chamber 141. The suction chamber 141 is installed on the top of the suction plate 119 and is connected to the inside of the suction plate 119. The upper two parts of the mounting frame 126 are equipped with suction plates 119. The bottom of the suction plates 119 is provided with evenly distributed suction ports 122. The suction plates 119 are respectively located on the left and right sides of the milling cutter 123.

[0038] Furthermore, in specific implementation, throughout the milling operation, the suction plate 119 moves synchronously with the fixed chamber 110 and the milling cutter 123, together with the lower limiting components one and two, to enclose a closed processing chamber, preventing metal chips from splashing outwards. The pump body in the fixed chamber 110 continuously generates negative pressure, which is introduced into the suction chamber 141 and the suction plate 119 through the connecting pipe 112. The chips and dust generated during milling are sucked into the pipeline from the suction port 122 and finally transported to the collection silo for centralized storage. The chips are cleaned in real time and will not remain inside the weight reduction groove, causing secondary cutting or scratching the bottom of the groove, while maintaining a clean processing environment. When the collection silo is full, it can be directly pulled out and dumped, making maintenance convenient.

[0039] The integrated electrical cabinet includes an integrated cabinet body and a base for supporting the integrated cabinet body, and the base is provided with multiple weight-reducing grooves.

[0040] Furthermore, in practical implementation, people can use milling equipment to mill grooves on the base of the electrical cabinet. The base is uniformly machined with standardized weight-reducing grooves. The depth, width, and spacing of the weight-reducing grooves are uniformly controlled by the built-in PLC program on the equipment control panel 106. The dimensional tolerances are stably controlled within the processing standards. After the weight-reducing grooves are opened on the base, the overall weight is reduced by 30%-45%. At the same time, the bottom follow-up support of the support frame 129 and the adaptive partitioning clamping process of the bottom compartment 133 retain the structural rigidity required for the cabinet to bear the load. Standard assembly positioning holes are reserved around the base, which can be directly bolted or welded to the bottom of the integrated cabinet without the need for secondary grinding and correction processes.

[0041] Working principle:

[0042] In practical use, the equipment can be used to mill grooves on the base of the electrical cabinet. Specifically, the base is first placed on the fixed platform 120 and positioned. Then, the vacuum pump 138 is started. Once the vacuum pump 138 is working, the connecting chamber 131 and the connecting frame 139 are connected through the connecting pipe 128, thereby extracting the gas inside the connecting frame 139 to create a negative pressure. This negative pressure is then applied to the base through the suction holes 130, thus fixing the base and preventing it from shifting during processing. The vacuum suction fixing structure uses existing technology; specific structural and installation details are not described in detail here. After the base is fixed, the equipment can be started to mill the grooves. During operation, the drive motor 109 drives the machine head 11. 6. The milling cutter 123 rotates at high speed. Then, the electric lifting platform 108 drives the related structure of the front milling cutter 123 to descend synchronously, so that the milling cutter 123 can make contact with the base and start milling grooves on the base. Then, the electric lead screw on the crossbeam 107 drives the electric lifting platform 108 and its upper milling components to move. The movement of the milling cutter 123 completes the milling of the groove. During the milling process, the ball screw at the bottom of the base frame 132 drives the base frame 132 and the upper base to move. The operation of the electric lead screw on the crossbeam 107 can realize the switching of the machining point, which is beneficial to the actual milling groove work. In the specific milling groove process, the operation of the electric lifting platform 118 drives the limit frame 1 15. The limiting frame 115, through the slider 121, drives the mounting frame 126 and its internal limiting components to move downwards synchronously, so that the bottom of the base 133 can fit against the top surface of the base. During the actual milling process, no matter how the fixed table 120 and its upper base move, the support frame 129 is always directly below the milling cutter 123. The support frame 129 can cooperate with the fixed table 120 to form a full-body support area directly below the bottom of the milling cutter 123, avoiding uneven resonance frequency due to partial suspension at the bottom of the base during milling, which can lead to vibration marks. This can effectively improve the quality of the finished product after milling. During this process, the limiting components can limit the downward pressure on the top of the base. In specific operation, the bottom of the base 133 is controlled by the bottom compartment 13. 3. This device can limit the base and allow the flexible bottom of the base chamber 133 to conform to the shape of the top surface of the base. During processing, power can be supplied to the excitation coils in the base chamber 133, causing the electromagnetic fluid in the base chamber 133 to become semi-solid, making the base chamber 133 a rigid whole. During milling, the excitation current of the corresponding excitation coils in each cavity can be changed according to the actual milling sequence, causing the electromagnetic fluid in each cavity to form different degrees of magnetorheological effect, thereby changing the overall stiffness of different areas of the base chamber 133. Simultaneously, through the synchronous extension and retraction of multiple electric push rods 136 at the bottom of the fixing bar 134, different downward pressures are applied to the corresponding pressure bar 135 at the bottom, causing the pressure bar 135 and the base chamber 133 to work together on different areas of the top of the base.As the milling cutter 123 continuously removes material, the remaining thickness of the base changes in different areas. By adjusting the excitation current of the corresponding excitation coil and the output stroke of the electric push rod 136, the base chamber 133 corresponding to the area with larger remaining thickness maintains higher overall rigidity and greater downward pressure, while the base chamber 133 corresponding to the area with smaller remaining thickness maintains lower overall rigidity and less downward pressure. This ensures that the flexible layer at the bottom of the base chamber 133 is always fully in contact with the base surface, avoiding localized clamping force concentration. Combined with the support frame 129, this creates a continuous and stable local constraint area above and below the processing area, thereby reducing vibration and deformation caused by changes in the local rigidity of the base. This improves the dimensional consistency and bottom processing quality of the weight-reducing groove during processing. During milling, the fixed chamber 110 moves synchronously with the electric lifting platform 108 and the milling cutter 123. Through the connecting pipe 112, it can drive the suction plate 119 to move synchronously, ensuring that the suction plate 119 is always located on the left and right sides of the milling area of ​​the milling cutter 123, moving synchronously around the processing area and interacting with the lower limiting group. Component 1 and limiting component 2 together form a local limiting space to block and restrict metal chips splashed during milling, preventing chips from scattering outside the processing area. When the pump in the fixed chamber 110 starts, a negative pressure is created inside the suction plate 119 through the connecting pipe 112 and the suction chamber 141. Metal chips and dust within the area enclosed by the suction plate 119 enter the suction plate 119 through the suction port 122, and are then transported sequentially through the suction chamber 141 and the connecting pipe 112 to the collection bin in the fixed chamber 110 for further processing. Centralized collection, because the fixed bin 110, connecting pipe 112, and suction bin 141 can always drive the suction disc 119 to move synchronously with the machining position of the milling cutter 123, ensures that the local limiting area always corresponds to the machining area. This confines the debris within the negative pressure suction range, improving suction efficiency and reducing debris scattering and the occurrence of secondary cutting or scratches on the bottom of the weight-reducing groove due to debris retention. It also facilitates subsequent unified cleaning of the collected debris in the collection bin, improving the machining environment and quality of the entire weight-reducing groove machining process.
