Description

Technical Field

[0001] This disclosure relates to the field of steel plate cutting edge removal technology, and more specifically, to a clamping mechanism for holding steel plates. Background Technology

[0002] Cutting marks on steel plates mainly consist of slag flaking and burrs, primarily located along the long side of the steel plate blank. These marks are caused by molten slag from the previous flame cutting process flowing down and solidifying. The size of the cutting mark varies depending on the cutting effect of the flame cutting machine, with a maximum thickness approaching 15mm and a minimum of approximately 2mm. In related technologies, steel plates require clamps to remove cutting marks; however, these clamps are often difficult to use stably to hold the steel plate securely. Summary of the Invention

[0036] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0037] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "front," "rear," "left," and "right" are used for ease of description based on the drawing orientations of the corresponding figures, while "inner" and "outer" are defined based on the contours of the corresponding components themselves. Terms such as "first" and "second" used in this disclosure are used to distinguish one element from another and do not have sequential or importance implications. Furthermore, when the following description refers to the figures, unless otherwise indicated, the same numbers in different figures represent the same or similar elements.

[0038] Please see Figures 1 to 3 An automated processing device for removing steel plate cutting nodules includes a clamping mechanism for holding the steel plate. The clamping mechanism includes a frame, a pressing component, an X-axis pushing component, and an X-axis positioning surface switching component. The frame 100 has a processing position 110 with a clearance groove 120 at its bottom, on which the steel plate 10 is placed. The clamping mechanism 300 includes a pressing component 310, an X-axis pushing component 320, and an X-axis positioning surface switching component 330. The pressing component 310 is installed on the side of the frame 100 away from the cutting nodules 11 and is used to press down the steel plate 10. The X-axis pushing component 320 is installed within the clearance groove 120. The X-axis positioning surface switching component 330 is offset from the X-axis pushing component 320 within the clearance groove 120 in the X direction. The X-axis pushing component 320 and the X-axis positioning surface switching component 330 are used to clamp the steel plate 10 in the X direction. The working principle is as follows: First, the steel plate 10 is placed above the clearance groove 120, and the pressing component 310 presses the steel plate 10 down to ensure its stability; then, the X-axis pushing component 320 and the X-axis positioning surface switching component 330 work together to move along the X-axis and accurately position the steel plate 10, providing precise clamping to ensure the high precision requirements of the subsequent removal of the cutting edge 11.

[0039] In one implementation, please refer to Figures 10 to 12Multiple pressing assemblies 310 are provided and spaced apart along the Y direction to ensure the stability and reliability of the pressing. The pressing assembly 310 includes a first standard hydraulic cylinder 311, a first pressure plate 312, a pressing bracket, and a pressing head 314. The first standard hydraulic cylinder 311 is mounted on the frame 100, and the output shaft of the first standard hydraulic cylinder 311 is hinged to one end of the first pressure plate 312. The pressing head 314 is mounted on the other end of the first pressure plate 312. The pressing head 314 is used to abut against the top surface of the steel plate 10. The middle part of the first pressure plate 312 is hinged to the pressing bracket, and the bottom of the pressing bracket 313 is fixedly connected to the frame 100. Specifically, there can be four pressing components 310, which are used to stably clamp the steel plate 10 onto the positioning block. The main clamping (pressing component 310) is a rocker arm hinge type. The main clamping cylinder is mounted on the frame 100 with four M24 screws. The front end of the cylinder piston rod is connected to the connector via an external thread. The connector is connected to the first pressure plate 312 via a pin. The first pressure plate 312 is connected to the pressing bracket via a connecting plate and a pin. The pressing head 314 is connected to the first pressure plate 312 via a pin. The pressing bracket is mounted on the frame 100. The cylinder and the pressing bracket are fixed. When the cylinder piston rod extends, the pressure plate swings around the pin. The pressing head 314 swings downward to achieve the clamping action. When the cylinder piston rod retracts, the pressing head 314 swings upward to achieve the releasing action.

[0040] The clamping mechanism 300 may also include a base. The pressing component 310, the X-axis pushing component 320 and the X-axis positioning surface switching component 330 are all mounted on the frame 100 through the base. Users can first assemble the components used in the clamping mechanism 300 on the base, and then directly fix the base to the frame 100 after assembly.

[0041] In one implementation, please refer to Figure 10 and Figure 15 The X-direction pushing assembly 320 includes a second standard hydraulic cylinder 321, a connecting block 322, a rotary hydraulic cylinder 323, and a second pressure plate 324. The second standard hydraulic cylinder 321 is installed in the clearance groove 120 through a cylinder seat. The output shaft of the second standard hydraulic cylinder 321 is fixedly connected to the connecting block 322. The rotary hydraulic cylinder 323 is installed at the end of the connecting block 322 away from the second standard hydraulic cylinder 321. The output shaft of the rotary hydraulic cylinder 323 is installed with the second pressure plate 324. The second pressure plate 324 is used to abut against the steel plate 10 in the X direction.

[0042] Specifically, the X-axis pushing assembly 320 consists of a 40mm diameter standard hydraulic cylinder, a rotary hydraulic cylinder 323, a cylinder seat, a pressure plate, a guide shaft 333, a guide rail seat, and a bearing seat 334. There are three sets of X-axis pushing components. The X-axis pushing assembly 320 and the X-axis positioning surface switching assembly 330 work together to clamp the steel plate 10 in the front-back direction. The second standard hydraulic cylinder 321 is mounted on the cylinder seat, which is fixed to the clamping body. The standard hydraulic cylinder drives the rotary hydraulic cylinder 323 and the second pressure plate 324 to move back and forth through two guide shafts 333 to achieve the pushing action. The rotary hydraulic cylinder 323 is mounted on a movable cylinder seat. When loading, the standard hydraulic cylinder is in the extended state, and the rotary hydraulic cylinder 323 is also in the extended horizontal state. When it is necessary to push the steel plate 10, the rotary hydraulic cylinder 323 swings up and retracts, and then the standard hydraulic cylinder retracts (i.e., in the vertical state), pushing the steel plate 10 against the X-axis reference surface for positioning.

[0043] In one implementation, please refer to Figures 10 to 16 The X-axis positioning surface switching assembly 330 includes a third standard hydraulic cylinder 331, a limiting block 332, a guide shaft 333, a bearing seat 334, and an L-shaped positioning block 335. The third standard hydraulic cylinder 331 is installed in the clearance groove 120 through a cylinder seat. The output shaft of the third standard hydraulic cylinder 331 passes through the limiting block 332 and is slidably connected to the limiting block 332. The end of the output shaft of the third standard hydraulic cylinder 331 is fixedly connected to the L-shaped positioning block 335. The vertical sidewall of the L-shaped positioning block 335 is used to abut against the X-axis of the steel plate 10, and the horizontal sidewall of the L-shaped positioning block 335 is used to support the steel plate 10. The guide shaft 333 is installed in the clearance groove 120 through a guide rail seat, and the L-shaped positioning block 335 is slidably connected to the guide shaft 333 through a slider. This achieves the switching of the X-axis positioning surface, allowing for the processing of steel plates 10 with different widths to meet processing requirements. The positioning of the steel plate 10 is divided into two positions: for steel plates 10 with a width of 320mm-475mm, the X-axis positioning cylinder needs to retract; for steel plates 10 with a width of 150mm-320mm, the X-axis positioning cylinder needs to extend. The X-axis reference positioning surface switching mechanism is fixed to the fixture body by mounting screws.

[0044] In one implementation, please refer to Figure 10 and Figure 13The clamping mechanism 300 also includes multiple steel plate positioning blocks 340 located above the clearance groove 120. The top surface of the steel plate positioning blocks 340 forms a grid surface and a striped surface. Specifically, it consists of 6 steel plate positioning blocks 340. The arrangement of the steel plate positioning blocks 340 on the clamp is designed to ensure that steel plates 10 with a length of 800-1700mm, a width of 147-475mm, and a thickness of 70-140mm can be positioned on the clamp. During loading, the steel plate 10 is placed directly onto the steel plate positioning blocks 340 of the clamping mechanism 300 by a large electromagnet. To increase the friction between the steel plate 10 and the positioning blocks, and considering that the lower surface of the steel plate 10 is not very smooth, the positioning blocks are made with two different pattern effects to avoid jamming when pushing the steel plate 10. The surface of the positioning blocks is made into a grid surface and a striped surface. Each positioning block is installed on the clamping body by 4 M10 screws.

[0045] In one implementation, please refer to Figure 10 and Figure 14 The clamping mechanism 300 also includes multiple auxiliary support cylinders 350, which are spaced apart along the Y direction on the frame 100 and located at one end of the cutting edge 11 of the steel plate 10 to support the steel plate 10. Their function is to support the wider steel plate 10; after the steel plate 10, approximately 475mm wide, is positioned and clamped on the clamp, there is a certain width below the machining surface side that cannot be supported by the steel plate positioning block 340, which would cause vibration during machining. To reduce the vibration of the steel plate 10 and increase the stability of the positioning and clamping, auxiliary support cylinders 350 are added below the machining surface side. After the main clamp clamps the workpiece, the front end of the auxiliary support extends out through the hydraulic circuit to support the underside of the steel plate 10. The auxiliary support cylinders 350 are mounted on the clamping body using four M10 screws.

[0046] See one implementation method Figure 10 The fixture mechanism 300 also includes a Y-direction blocking block 360, which is mounted on the frame 100 and used to abut against the steel plate 10 in the Y direction. Because the cutting force is relatively large and there is no positioning and clamping in the Y direction, a blocking block is needed during the machining process to ensure that the steel plate 10 will not fall out of the fixture when the cutting force is greater than the clamping force.

[0047] Please see Figures 10 to 15 as well as Figure 18Before the steel plate 10 is loaded, the loading platform identifies the size of the steel plate 10 and sends the size information of the steel plate 10 to the processing equipment. If the width of the steel plate 10 is greater than or equal to 320mm, the cylinder of the X-axis positioning surface switching component 330 retracts. If the width of the steel plate 10 is less than 320mm, the cylinder of the X-axis positioning surface switching component 330 extends, and the reference surface is switched. The positioning switching action corresponds to the X-axis positioning surface switching component 330. The rotation clamping / releasing action is the X-axis pushing front-end rotation cylinder 323. The pushing clamping / releasing action is the standard cylinder of the X-axis pushing component 320. The main clamping / releasing action is the action of the main clamping mechanism cylinder. The auxiliary clamping / releasing action is the auxiliary support mechanism.

[0048] Advantages of the clamping mechanism 300:

[0049] 1. This fixture solves the problem of clamping and positioning steel plates 10 within the required size range.

[0050] 2. This fixture can meet the machining and cutting needs of steel plates 10 with different widths by switching the X-axis positioning surface switching component 330.

[0051] 3. This mechanism can be widely used in steel plate processing equipment.

[0052] 4. This fixture has high rigidity and can meet the needs of heavy cutting.

[0053] In one implementation, please refer to Figures 1 to 3 as well as Figure 6The automated processing equipment for removing cutting marks from steel plates also includes a cutting mechanism 400. The cutting mechanism 400 includes a first motor 410, a small pulley 420, a large pulley 430, a synchronous belt 440, a mechanical spindle 450, and a tool-removing cylinder 460. The first motor 410 is mounted on the slide plate of the Y-axis moving mechanism 220 via a motor bracket. The small pulley 420 is sleeved on the outer circumference of the output shaft of the first motor 410 and fixedly connected to it. The large pulley 430 is sleeved on the rear end of the mechanical spindle 450. The synchronous belt 440 is wound around the small pulley 420 and the large pulley 430. The tool-removing cylinder 460 is mounted on the motor bracket and located at the rear end of the mechanical spindle 450. The tool-removing cylinder 460 is used to release the tool 560 on the front end of the mechanical spindle 450. Here, the small pulley 420 and the large pulley 430 refer to the diameter of the pulleys. The tool changer cylinder 460 is mounted on the motor bracket. The motor has a rated speed of 590 r / min, and the spindle output speed is reduced to 278 r / min via a synchronous belt pulley 440 with a reduction ratio of 34:72. The mechanical spindle 450 is a BT50 model. To achieve automatic tool changing, the tool changer cylinder 460 is installed at the rear end of the spindle. The tool changer cylinder 460 is mounted on the motor bracket at the rear end of the mechanical spindle 450. During tool changing, the spindle needs to be positioned, so a spindle positioning recognition switch is installed at the rear end of the spindle. The spindle assembly is connected to the slide assembly via an X-axis guide rail. Specifically, the tool changer cylinder 460 provides thrust through a hydraulic system, pushing the drawbar forward, thereby releasing the clamp on the spindle and allowing the tool 560 to be changed. During this process, the spindle remains stationary, while the tool changer cylinder 460 uses its internal mechanical structure (such as a disc spring and a locking mechanism) to counteract the axial force during tool changing, thus protecting the spindle bearings from damage.

[0054] In one implementation, please refer to Figure 6 The cutting mechanism 400 also includes a spindle positioning switch 470 and a first sensor 480. The spindle positioning switch 470 and the first sensor 480 are mounted on the rear housing of the mechanical spindle 450. The first sensor 480 detects the rotation of the mechanical spindle 450, and the spindle positioning switch 470 is used for spindle positioning. The first sensor 480 identifies whether the mechanical spindle 450 is rotating. If the mechanical spindle 450 does not rotate when the motor is rotating, it can be determined that the timing belt 440 is broken. The working principle of the spindle positioning switch 470 and the first sensor 480 is existing technology and will not be detailed here.

[0055] In one implementation, please refer to Figures 1 to 5The motor bracket has a first protrusion and a second protrusion at its bottom. The sliding plate of the Y-axis moving mechanism 220 has two Y-axis stops 221 and two Y-axis limit switches 222. The two Y-axis stops 221 are arranged opposite each other along the Y-axis, and the two Y-axis limit switches 222 are also arranged opposite each other along the Y-axis and located on the outer sides of the two Y-axis stops 221. The first protrusion abuts against the Y-axis stops 221, and the second protrusion abuts against the Y-axis limit switches 222. The Y-axis limit switches 222 and the Y-axis stops 221 represent the soft and hard limit positions of the cutting mechanism 400 in its Y-axis travel, respectively, serving as travel protection. Also considering the rigidity of the equipment, the sliding plate is cast. The sliding plate is connected and installed to the frame 100 via an X-axis guide rail and a slider. The cutting mechanism 400 can move in the Y-axis relative to the sliding plate of the Y-axis moving mechanism 220.

[0056] Two X-direction stops and two X-direction limit switches 132 are installed on the slide plate of the X-direction moving mechanism 210. The bottom of the slide plate of the Y-direction moving mechanism 220 has a third protrusion and a fourth protrusion. The two X-direction stops 131 are arranged opposite each other along the X-direction, and the two X-direction limit switches are arranged opposite each other along the X-direction and located outside the two X-direction stops. The third protrusion is used to abut against the X-direction stops, and the fourth protrusion is used to abut against the X-direction limit switches. The X-direction limit switches and X-direction stops represent the soft and hard limit positions of the cutting mechanism 400 in the X-axis travel, serving as travel protection. Also considering the rigidity of the equipment, the slide plate is made of cast iron. The slide plate of the Y-direction moving mechanism 220 is connected to the slide plate of the X-direction moving mechanism 210 via an X-axis guide rail and a slider. The slide plate of the Y-direction moving mechanism 220 can move relative to the slide plate of the X-direction moving mechanism 210 in the X-direction. The slide plate of the X-direction moving mechanism 210 is fixed to the frame 100.

[0057] In one implementation, please refer to Figures 1 to 3 as well as Figure 9 The automated machining equipment for removing cutting nodules from steel plates also includes a tool changing mechanism 500. The tool changing mechanism 500 includes a tool changing support 510, a Y-axis transverse cylinder 520, a lifting cylinder 530, and two tool holders 540. The Y-axis transverse cylinder 520 is mounted on the tool changing support 510, and the lifting cylinder 530 is mounted on the output shaft of the Y-axis transverse cylinder 520 via a connecting plate. The two tool holders 540 are mounted on the output shaft of the lifting cylinder 530. The function of the tool changing device is to enable operators to automatically change tools outside the equipment. For details of the specific tool changing actions, please refer to the appendix below. Figure 18 The entire tool changer is connected and installed to the base.

[0058] In one embodiment, a first position switch 551 is installed on the tool changer support 510, a first abutment and a second position switch 552 are installed on the connecting plate, the first abutment is used to abut against the first position switch 551, and a second abutment is installed on the output shaft of the lifting cylinder 530, the second abutment is used to abut against the second position switch 552.

[0059] In one implementation, please refer to Figures 1 to 3 as well as Figure 7 Both the X-axis moving mechanism 210 and the Y-axis moving mechanism 220 include a driving component 211. The driving component 211 includes a first lead screw 2111, a second motor 2112, a lead screw nut 2113, and a lead screw support 2114. The second motor 2112 and the lead screw support 2114 are both mounted on the sliding plate of the moving mechanism. The first lead screw 2111 is connected to the output shaft of the second motor 2112. The lead screw nut 2113 is sleeved on the first lead screw 2111 and screwed to the first lead screw 2111.

[0060] In one implementation, please refer to Figure 1 and Figure 8 The automated processing equipment also includes a guide rail protector 610 and a lead screw protector mounted on a sliding plate. The guide rail protector 610 is a steel pull-out cover, dustproof, waterproof, and oil-resistant, protecting the linear guide rail; reducing damage to the linear guide rail from machining chips, and increasing its service life; the guide rail protector 610 includes a side protective plate 621, a front pull-out cover 622, and a rear pull-out cover 623. The protective cover is mounted on the motor bracket of the cutting mechanism 400. Alternatively, in other embodiments, the motor bracket can be connected to the Y-axis moving mechanism 220 via the sliding plate, completely enclosing the X-axis guide rail and lead screw within the protective cover.
