Description

Technical Field

[0001] The invention belongs to the field of machine tool protection and relates to a linkage door device, in particular to a linkage door device for protecting a gantry machining center machine tool. Background Art

[0002] As an important functional component of CNC machine tools, machine tool external protection has the functions of safety protection, precision maintenance, environmental protection, moisture and humidity isolation, and is increasingly valued by machine tool manufacturers and machine tool end users.

[0003] Compared with conventional machining center machine tools, gantry machining centers are mainly suitable for machining large workpieces. Their size and structure are larger than other machining centers. Therefore, the protective cover of the gantry machining center is usually designed in the form of a protective fence, that is, a circle of protective fences is set around the gantry machining center to surround the processing area, thereby achieving safety protection and sealing and leak prevention of the gantry machining center.

[0004] In the prior art, there are two types of protective fences for gantry machining centers: the first is to set a higher fixed protective fence around the gantry machining center, and set a lower fixed fence under the beam to avoid interference with the beam after it moves down, and to facilitate machine tool operators to cross the fixed fence and enter and exit the inside and outside of the machine tool processing area. The second is to set a sliding door under the beam. When the beam moves down, the sliding door needs to be manually moved away to avoid the collision between the protective door and the beam. However, in the above solution, cutting fluid and chips will splash out from under the beam during machine tool processing, which not only pollutes the environment around the machine tool and is difficult to clean, but also poses safety risks such as slipping and falling. The opening and closing of the sliding door has poor controllability, and there is a potential accident risk of collision between the beam and the sliding door. Summary of the invention

[0005] In order to overcome the defects existing in the prior art, the present invention proposes a linkage door device, which can move in the horizontal direction to ensure that the machine tool operator can easily enter and exit the machine tool protective fence; and can also move up and down with the crossbeam to ensure that the linkage door device and the machine tool crossbeam have good sealing performance during machine tool processing, thereby achieving the function of sealing and leak prevention. In addition, the linkage door device is also provided with a detection and control unit, which can automatically control the movement of the door body, and has the characteristics of intelligence, safety, and efficiency, which can effectively improve the overall performance of the machine tool.

[0006] A technical solution adopted by the present invention to solve its technical problems is: a linkage door device, including a fixed enclosure, a sliding door assembly, a telescopic assembly, a control assembly, a sliding guide assembly, a rolling support assembly, and a slide cylinder, wherein the bottom end of the fixed enclosure is fixed to the ground and a portion of it is provided with a notch, and the top end is connected to one end of the sliding guide assembly; the rolling support assembly is matched and embedded in the notch, and one side is fixed to the ground; the top end of the sliding door assembly is connected to the other end of the sliding guide assembly, and the bottom end is connected to the other side of the rolling support assembly; one end of the slide cylinder is connected to the running end of the sliding door assembly away from the fixed enclosure, and the other side is connected to a side surface of the telescopic assembly in the telescopic direction; the control assembly is electrically connected to the rolling support assembly and the slide cylinder; the sliding door assembly is driven and controlled by the control assembly to move horizontally and the telescopic assembly vertically; the sliding door assembly drives the telescopic assembly to move horizontally.

[0007] By connecting the sliding door assembly with the telescopic assembly, the linkage door device can simultaneously realize the linkage of horizontal and vertical movement, with higher working efficiency and better intelligent effect. At the same time, since the slide cylinder is connected to the sliding door assembly and the telescopic assembly respectively, the sliding door will drive the telescopic assembly to move together when it is running, which not only increases the horizontal sliding stroke but also reduces the size of the sliding door.

[0008] Preferably, the rolling support assembly includes a support frame, a rolling guide rail, a drive motor, and a transmission structure, wherein one side of the support frame is fixed to the bottom surface, and the other side is connected to the rolling guide rail; the drive motor is fixed to the support frame and connected to one end of the transmission structure; the other end of the transmission structure is fixed to the bottom of the sliding door assembly.

[0009] By driving the transmission structure connected with the support frame and the sliding door assembly through the driving motor, the horizontal movement of the sliding door assembly relative to the support frame can be realized, and the structure is simple and easy to realize.

[0010] Preferably, the sliding structure is a gear rack combination, a lead screw nut combination, or a slider guide rail combination.

[0011] The transmission structure can adopt gear, rack meshing transmission or screw nut cooperation operation or linear operation of slider and guide rail. It can be flexibly selected according to the specific working conditions. The selection range is wide and the use is simple and convenient.

[0012] The sliding door assembly includes a sliding door, a plurality of rolling bodies, and a guide rail limiting groove. The rolling bodies are connected to the bottom of the sliding door at intervals and match the rolling guide rails; the guide limiting grooves are fixed to the top of the sliding door; the sliding guide assembly is fixed to the top of the fixed enclosure and slidably cooperates with the guide limiting grooves.

[0013] The arrangement of the rolling body at the bottom of the sliding door can make the sliding door run more smoothly and the motor drive more labor-saving; the sliding guide assembly cooperates with the guide limit groove to make the guidance of the sliding door more stable.

[0014] Furthermore, the rolling body includes two rollers, a roller shaft, and a roller bracket. Both ends of the roller shaft are embedded in the inner ring of the rolling bearing. Each roller is mounted on the outer ring of the rolling bearing to form a roller as a whole. The roller as a whole is installed on the roller bracket.

[0015] By arranging the rollers at intervals, the rolling guide rails on the rolling support assembly can be embedded in the opposite sides of the rollers to make them contact and fit. In this way, the rollers can play a limiting role to ensure the consistency of the sliding direction of the sliding door, so that the sliding is smooth and stable with more uniform force, and the protective seal is also guaranteed.

[0016] Preferably, the telescopic assembly includes a fixed guard plate, several sections of sliding guard plates of matching shapes, several guard plate rollers, several guard plate roller grooves, guide strips, and guide grooves. The fixed guard plate is similar in shape to each of the sliding guard plates and is nested together; each of the guard plate roller grooves and the guide groove are fixedly connected at intervals on a plane of the side of the sliding door away from the fixed enclosure; the fixed guard plate is fixedly connected to the bottom of the sliding door; each of the guard plate rollers is fixedly connected to the sliding guard plate respectively and the rollers are matched and embedded in the guard plate roller grooves; the guide strips are fixedly mounted on the sliding guard plate close to the side of the sliding door and embedded in the guide grooves; the slide cylinder is connected to one of the sliding guard plates.

[0017] By designing the structure of the telescopic component in imitation of the structure of the guide rail protective cover, the structure is simple and the cost is low. Not only can the up and down telescopic movement be realized, the telescopic stroke is controllable, and the application range is wide.

[0018] Preferably, it also includes a sealing assembly, which includes a strip brush, a scraper plate, and a guide plate, wherein the strip brush is fixed to the top of the sliding guard plate and the side of each other guard plate away from the sliding door; the scraper plate is arranged in the gap between each section of the guard plate and fixed on the adjacent guard plate; the guide plate is fixed to the bottom of the fixed enclosure, the bottom of the sliding door and the bottom of the telescopic assembly.

[0019] By installing and applying the sealing component, not only the sealing of the linkage door device is guaranteed, but also the splashed liquid can be recycled through the guide plate, which not only improves the environment but also saves costs.

[0020] Preferably, the sliding guide assembly includes a sliding guide rail, and the sliding guide rail is made of nylon material. Using nylon material as the sliding guide rail can increase the wear resistance of the guide rail, extend the service life of the guide rail, reduce the replacement frequency, and the nylon material is easy to process and low in cost.

[0021] Furthermore, a gantry machining center machine tool includes a column, a crossbeam, a fence, and also includes the above-mentioned linkage door device, and the linkage door device is connected to the fence.

[0022] The machining center machine tool can achieve horizontal and vertical linkage by adopting a linkage door device. When the machine is processing workpieces, it can quickly and automatically avoid obstacles, which is safe and efficient while improving the level of automation.

[0023] It can be seen from the above technical solution that at least one beneficial effect brought by one aspect of the present invention is that, by creatively combining the sliding door assembly with the telescopic assembly, not only a stable and convenient new type of protective linkage structure is provided, but also the linkage of horizontal and vertical movement can be simultaneously satisfied. Through the control of the control assembly, not only the manual participation is reduced, but also the automation level is improved while being safe and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Refer to the attached Figure 1 With attached Figure 2 As shown, the linkage door device 10 includes a fixed enclosure 100, a sliding door assembly 200, a telescopic assembly 300, a sliding guide assembly 400, a rolling support assembly 500, a slide cylinder 600, a control assembly 700, and a sealing assembly 800. The bottom of the fixed enclosure 100 is fixed to the ground by expansion bolts, serving as a sliding support frame of the linkage door assembly 200; a notch is also provided at the bottom, and the rolling support assembly 500 is embedded in the corresponding notch and fixed on the ground on one side. The sliding door assembly 200 is arranged parallel to the fixed enclosure, the bottom end is connected to the other side of the rolling support assembly, the top end is connected to one end of the sliding guide assembly 400, and one side thereof is connected to the fixed enclosure 100. One side of the telescopic assembly 300 is connected to the sliding door assembly away from the fixed enclosure. The other end of the sliding guide assembly 400 is fixedly connected to the top of the fixed enclosure 100 near the sliding door assembly 200. The control assembly 700 is electrically connected to the rolling support assembly and the slide cylinder, and can control and drive the rolling support assembly and the slide cylinder. In this way, the rolling support assembly can provide the sliding door assembly with support power for upward support and driving power for forward and backward sliding; the sliding guide assembly can provide a guiding and limiting function for the sliding door assembly. Driven by the rolling support assembly 500, the sliding door assembly can slide forward and backward along the fixed enclosure (as shown in the direction of the arrow in the figure). One end of the slide cylinder 600 is fixedly connected to the end of the sliding door assembly away from the fixed enclosure, and the other end is connected to a side of the telescopic assembly 300 in the telescopic direction. In this way, the telescopic assembly can be driven to telescope up and down along the sliding door assembly through the telescopic drive of the slide cylinder. Furthermore, since the telescopic assembly is connected to the slide cylinder on the sliding door assembly, the telescopic assembly can move forward and backward with the sliding door assembly, thereby realizing the linkage function and increasing the movement stroke.

[0041] Embodiment 2

[0042] Refer to the attached Figure 3As shown, the rolling support assembly 500 includes a support frame 510, a rolling guide rail 520, a driving motor 530, a sliding structure 540, a guide rail connecting plate 550, and a guide rail connecting member 560. One side of the support frame can be fixed to the ground by bolts, and a guide rail connecting plate 550 is fixed on the other side along the length direction. On one side of the connecting plate, the driving motor 530 is fixedly connected to the support frame, and a plurality of guide rail connecting members 560 are arranged at intervals on the side of the other side, and the other end of the connecting member is connected to the rolling guide rail 520 by bolts. The driving motor is connected to one end of the transmission structure 540. In this embodiment, the transmission structure 540 uses a gear 541 meshing with a rack 542. That is, the output shaft of the driving motor is connected to the gear 541; one end of the rack 542 is meshed with the gear for transmission, and the other end is fixed to the bottom of the sliding door assembly 200. In this way, the driving motor starts the driving gear to rotate, and the gear drives the sliding door assembly connected to the rack to run in a straight line. That is, the sliding of the sliding door assembly is realized.

[0043] The sliding structure 540 can also be a screw-nut combination or a slider-guide combination. It should be noted that when the slider-guide combination is used, the output shaft direction of the drive motor needs to be adaptively changed. The drive motor can be replaced with a drive element such as a cylinder or an electric cylinder. The specific working principle is similar to that of this embodiment and will not be repeated here.

[0044] Embodiment 3

[0045] See attached Figure 4 To Attachment Figure 6 As shown, the sliding door assembly 200 includes a sliding door 210, a plurality of rolling bodies 220 arranged at intervals at the bottom of the sliding door, and a guide rail limiting groove 230 located at the top of the sliding door. Further, the rolling body 220 includes two rollers 221, two roller shafts 222, and a roller bracket 223. One end of each roller shaft is respectively embedded in the inner ring of the rolling bearing, and then the rollers 221 are respectively mounted on the outer ring of the rolling bearing, and then the other ends of the roller shafts are respectively fixedly installed on the roller bracket 223 at intervals and collinearly, and then the roller bracket is fixedly connected to the bottom of the sliding door. It is best to place the two rollers in a vertical row, and the gaps between them match the width of the rolling guide rail. Through the interval arrangement between the rollers, the rolling guide rail 520 can be embedded in the opposite sides of the two rollers to make them contact and match. In this way, the sliding door can slide in the two rollers driven by the rolling guide rail, making the sliding more stable and smooth. Auxiliary components such as observation windows and handles can be set on the sliding door as needed to help operators observe the working process of the machine tool.

[0046] The sliding guide assembly includes a sliding guide rail 410, which is fixedly installed on the top of the fixed enclosure 100. The guide rail limit groove 230 installed on the top of the sliding door is installed in cooperation with the sliding guide rail 410, so that the sliding door can run along the sliding guide rail under the drive of the guide rail limit groove. Through the limit guide of the sliding guide rail, the sliding door can slide smoothly and stably, the load is reduced, and the deformation and sealing are also guaranteed.

[0047] It should be noted that the sliding rail and the guide limit groove can be fixed to the fixed enclosure and the sliding door by bolts. The sliding rail can be made of nylon material to increase its wear resistance. Of course, any material with good wear resistance can be used as the sliding rail, and the specific type is selected according to the actual situation.

[0048] Embodiment 4

[0049] In this embodiment, the telescopic assembly is illustrated using two sections of sliding guard plates as an example, and can be flexibly changed according to actual working conditions during use.

[0050] See attached Figure 7 and attached Figure 8 As shown, the shrink assembly 300 includes a fixed guard plate 310, a first section sliding guard plate 320, a second section sliding guard plate 330, a guard plate roller 340, a first section sliding guard plate roller groove 350, a second section sliding guard plate roller groove 360, a guide bar 370, and a guide groove 380. The fixed guard plate, the first section sliding guard plate, and the second section sliding guard plate are formed by bending thin steel plates, and their cross-sections can be U-shaped or I-shaped structures, and a vertical plate is provided at one end of the running direction. The guard plates are similar in shape and can be nested with each other. When the vertical plate of the rear guard plate contacts the vertical plate of the front guard plate, the rear guard plate can continue to move and push the front guard plate to run. For details, please refer to the structure of the machine tool guide rail protective cover, which is a structure well known to those skilled in the art and will not be described in detail here.

[0051] The first section sliding guard plate roller groove 350, the second section sliding guard plate roller groove 360 ​​and the guide groove 380 are vertically spaced and fixedly connected on the side of the sliding door 210 away from the fixed enclosure 100. The fixed guard plate 310 is fixedly connected to the bottom of the sliding door 210 by a thread, so that it can slide forward and backward with the sliding door. Further, the guard plate roller 340 is fixedly connected to one side of the first section sliding guard plate 320 and the second section sliding guard plate 330, respectively, and its position matches the first section sliding guard plate roller groove and the second section sliding guard plate roller groove. Then the guard plate rollers installed on the guard plate are respectively embedded in the first section sliding guard plate roller groove 350 and the second section sliding guard plate groove 360 ​​on the sliding door. It should be noted that during installation, the first section sliding guard plate is embedded in the fixed guard plate according to the shape of the guard plate, and then the second section sliding guard plate is embedded in the first section sliding guard plate, so that the first section sliding guard plate can slide up and down relative to the fixed guard plate, and the second section sliding guard plate can slide up and down relative to the first section sliding guard plate. Furthermore, the guide strip 370 is fixedly mounted on the second section of the sliding guard plate near the side of the sliding door and is embedded in the guide groove 380. In this way, when the guard plate moves up and down, each guard plate is guided by its own bending shape, and the guide strip is also guided in the guide groove. The double-layer guide structure makes the guard plate run with a smaller load, runs smoothly and smoothly, and can also increase the running speed. Further, the slide cylinder 600 is connected to the second section of the sliding guard plate. In this way, the movement of the sliding cylinder can drive the movement of the second section of the sliding guard plate, and the movement of the second section of the sliding guard plate will drive the movement of the first section of the sliding guard plate. It should be noted that the linkage between each section of the guard plate can also be achieved through a scissor-shaped hinge, such as: a steel plate-type guide rail protective cover telescopic structure. Of course, any structure that can achieve the telescopic structure of the guard plate is acceptable, and this embodiment does not make specific restrictions.

[0052] Embodiment 5

[0053] Refer to the attached Fig. 9As shown, the linkage door device also includes a control component 700. The control component includes a control box (not shown), a first induction switch 710, a first induction plate 720, a second induction switch 730, a second induction plate 740, a third induction switch 750, a third induction plate 760, and an alarm. The first induction switch 710 is fixedly mounted on the top of the sliding door near one end of the telescopic component, and the first induction plate 720 is fixedly mounted on the top of the fixed enclosure near one end of the sliding door, and the height matches the first induction switch. In this way, when the sliding door is running, the induction switch can sense the first induction plate and send a signal to the control box, and the control box controls the drive motor according to the induction signal, thereby realizing the control of the sliding door sliding forward and backward. The second induction switch 730 and the third induction switch 750 are respectively fixedly mounted on the upper and lower ends of the sliding door near the telescopic component, and their positions are also the upper and lower limit positions of the telescopic component 300. The second induction plate 740 and the third induction plate 760 are fixedly mounted on the side of the second section sliding guard plate near the sliding door. In this way, when the telescopic component moves up and down, the induction plate on the second sliding guard plate contacts the induction switch, which can send a signal to the control box to control the travel of the telescopic component. The application of the control component can free up manual labor, avoid accidents, and improve automation and intelligence. It should be noted that the induction switch can be a proximity switch.

[0054] The alarm is installed on the upper part of the sliding door. When the machine tool is working, if someone manually opens the sliding door, the control box will send a signal to the alarm. At this time, the alarm will start and sound, reminding the operator that this is an illegal operation.

[0055] Embodiment 6

[0056] Please refer to the attached Fig. 9 As shown, the linkage door device also includes a sealing component 800, and the sealing component 800 includes a strip brush 810, a scraper plate (not shown in the figure), and a guide plate 820. The strip brush 810 is respectively fixed to the side of each section of the guard plate away from the sliding door and the top of the second section of the sliding guard plate, which can play a certain sealing role. The scraper plate is fixed in the gap between the mutually matched sections of the guard plates and is fixedly installed with one of the guard plates. In this way, the guard plate also plays a sealing role during operation. The guide plate 820 is fixedly installed at the bottom of the fixed enclosure 100, the sliding door 210 and the telescopic component 300, and is at an oblique angle, which can drain the splashed liquid to the designated position, on the one hand to improve the working environment, on the other hand to recycle the liquid and reduce costs.

[0057] Embodiment 7

[0058] See attached Fig.10As shown, a gantry machining center machine tool protection includes a linkage door device 10, a column 20, a beam 30, a spindle 40, a worktable 50, a left fence 60, and a right fence 70. The linkage door device is symmetrically arranged on both sides of the machining center beam. The side of the linkage door device with a telescopic component is connected to the machine tool, and the side with a fixed enclosure is respectively connected to the left fence and the right fence, so as to form a gantry machining center machine tool protection.

[0059] The crossbeam 30 is installed on the column 20 and moves up and down, the spindle 40 moves left and right on the crossbeam 20, and the workbench 50 moves forward and backward. The left fence and the right enclosure are fixed to the ground with bolts to block the splashing liquid generated during the machine tool processing. When processing workpieces, the spindle needs to move up and down and the workbench needs to move forward and backward. Therefore, under some working conditions, the machine tool crossbeam needs to move downward, and the traditional structure may cause a collision; there are also some working environments that require operators to enter and exit to check, turn over parts, etc. On the one hand, the traditional structure has no violation prompts, and on the other hand, the working environment is harsh and may cause work injuries. The use of a linkage door device can not only avoid personal injury and reduce the hidden dangers of crossbeam collision, but also improve the level of equipment automation, improve the overall quality of the equipment, and thus improve the user experience.

[0060] The specific working process is as follows:

[0061] When the machine tool is working, when the crossbeam moves to the top of the linkage door device, the linkage door device receives the signal, and the control box issues a command, and the slide cylinder drives the telescopic assembly to move downward. When it moves down to the third induction plate, the third induction switch sends a signal to the electric control box, and the electric control box issues a command to the drive motor, and then the drive motor rotates to drive the sliding door to slide in the direction of the fixed enclosure, and stops when the first induction switch senses the first induction plate. In this way, the linkage of the sliding door is automatically realized. The strip brushes, scraper plates, etc. installed on the telescopic assembly can achieve sealing on both sides of the machine tool column, effectively preventing the machine tool cutting fluid from splashing to the protective exterior. It not only improves the working environment, but also avoids the hidden danger of slipping and falling caused by cutting fluid.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
