Description

Technical Field

[0001] The utility model relates to the technical field of six-sided drilling equipment, in particular to a movable lifting workbench. Background Art

[0002] A six-sided drill is an efficient drilling equipment with multiple functions, capable of drilling, perforating, etc., and performing horizontal and vertical drilling; compared with conventional manual drilling, the six-sided drill can greatly improve the processing efficiency and accuracy. With the continuous development of science and technology, at present, the processing procedures of sheet materials all adopt processing equipment with a relatively high degree of automation, such as six-sided drills and panel saws. The existing woodworking processing equipment usually has a fixed workbench surface, or a workbench surface that moves as a whole single workbench.

[0003] The workbench surface of the six-sided drill often has a drill pit slot for avoiding the horizontal drill. When vertical holes need to be drilled or grooves need to be milled, when the drill bit passes through the avoidance pit of the horizontal drill, a phenomenon of air pressure will occur, and there is no supporting surface below, which will cause an accuracy error in the processing depth. Summary of the Utility Model

[0004] The utility model aims to at least solve one of the technical problems existing in the prior art. For this reason, the utility model provides a movable lifting workbench, which can avoid the horizontal drill by descending or moving forward and backward. When vertical holes need to be drilled or grooves need to be milled, the lifting workbench surface can be raised to level the entire workbench, or move forward and backward in cooperation with the fixed workbench to drill vertical holes or mill grooves, so as to avoid the air pressure phenomenon and resulting processing errors.

[0005] The utility model provides a movable lifting workbench, including a workbench base, a work platform, a first driving device, a fixed workbench, and a pressing wheel for pressing the sheet material; the work platform is arranged opposite to the fixed workbench; the workbench base is connected to the work platform through a sliding component; the fixed end of the first driving device is installed on the workbench base, and the movable end is connected to the work platform and drives the work platform to be close to or away from the fixed workbench along a first direction; the work platform includes a front workbench surface on the side away from the fixed end of the first driving device, a rear workbench surface on the side close to the fixed end of the first driving device, and a plurality of lifting workbench surfaces located between the front workbench surface and the rear workbench surface; the plurality of lifting workbench surfaces are linearly distributed along a second direction, and the second direction is perpendicular to the first direction.

[0006] The sliding door according to the embodiment of the present utility model has at least the following beneficial effects: The six-sided drill needs to process six surfaces of the board. When drilling the board in the horizontal direction, since the workbench surface of the six-sided drill is a whole plane, it is necessary to open a clearance pit for the horizontal drill. When drilling or milling in the vertical direction, part of the board located in the clearance pit lacks the support of the whole plane, resulting in processing errors. The present utility model creates or fills the clearance pit for the horizontal drill through a liftable workbench surface. When using the horizontal drill, the workbench surface descends to clear the horizontal drill; or when processing the side of the board close to the fixed workbench, the gap between the fixed workbench and the work platform is controlled by moving the work platform back and forth to clear the horizontal drill. When using the drill in the vertical direction, the workbench surface rises to fill the whole workbench surface to support the board, reducing processing errors.

[0007] As a preferred solution, a plurality of second driving devices for driving the liftable workbench surface to reciprocate in the vertical direction are provided on the bottom surface of the liftable workbench surface.

[0008] As a preferred solution, the fixed end of the second driving device is fixed to the work platform, and the movable end is connected to the bottom surface of the liftable workbench surface.

[0009] As a preferred solution, a synchronous balance structure is provided at the bottom of the liftable workbench surface for the second driving devices to lift the liftable workbench surface synchronously. Since a plurality of second driving devices are provided on the bottom surface of the liftable workbench surface, in order to avoid the unbalanced force on the liftable workbench surface caused by the asynchronous lifting of two or more second driving devices, a synchronous balance structure is provided to balance the acting forces of the second driving devices, making the force on the liftable workbench surface more uniform.

[0010] As a preferred solution, the synchronous balance structure includes a balance rod and a balance arm with the central axis parallel to the second direction; the balance rod is fixed to the bottom of the liftable workbench surface, and both ends are connected to the work platform through the balance arm; one end of the balance arm is connected to the balance rod through a bearing, and the other end is hinged to the work platform.

[0011] As a preferred solution, the sliding assembly includes a slider provided on the table base and a slide rail provided on the bottom surface of the work platform and cooperating with the slider. The slide rail and the slider have the advantages of high positioning accuracy and less wear, can achieve stable and non-trembling movement, and can ensure the stability of the work platform during movement. Since the work platform needs to move in a straight line, the cooperating slide rail and slider are beneficial to restricting the moving direction of the work platform.

[0012] As one of the preferred solutions, a number of supporting legs are provided on the bottom surface of the table base. The legs are used to fixedly support the table base and improve the stability of the installation of the table base.

[0013] As one of the preferred solutions, both the first driving device and the second driving device are cylinders. Cylinders have the advantages of being structurally compact, having a fast execution speed, and being flexible in installation and configuration. By using cylinders, simple linear motion can be quickly completed, and their inherent telescopic function can meet the requirements of the horizontal movement of the work platform and the lifting movement of the lifting workbench surface.

[0014] As one of the preferred solutions, the movable lifting workbench further includes a drill bit for processing the plate.

[0015] As one of the preferred solutions, the drill bit includes a horizontal drill, an upper drill head, and a lower drill head.

[0016] Other features and advantages of the present utility model will be described in the subsequent description, and in part, will become apparent from the description or will be understood by implementing the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In the description of the present utility model, it should be noted that terms such as "set", "installed", and "connected" should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0027] The technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the following described embodiments are some embodiments of the present utility model, not all embodiments.

[0028] The working surface of a six-sided drill is generally a complete plane, and there is a certain distance between the bottom of the horizontal drill 9 and the drill bit of the horizontal drill 9, as Figure 4 shown. Therefore, when using the horizontal drill 9 to process the board 10, the working surface needs to be provided with a clearance pit so that the drill bit can be aligned with the processing position of the board 10. However, after the working surface is provided with a clearance pit, when vertical drilling or milling is required for the board 10, due to the unevenness of the working surface, when the vertical drill bit presses on the part of the board 10 located in the clearance pit, the board 10 will be deformed due to uneven bottom support, resulting in uneven stress on the board 10 and further causing processing errors.

[0029] In order to be able to achieve clearance for the horizontal drill 9 and enable the board 10 to obtain a flat support, an embodiment of the present utility model provides a lifting platform, as Figure 1As shown in the figure, the lifting platform includes a table base 1, a sliding assembly 4, a driving device, and a working platform 2. Specifically, the table base 1 and the working platform 2 are connected by the sliding assembly 4, enabling the working platform 2 to slide on the table base 1. The first driving device 3 is used to drive the sliding of the working platform 2. Among them, the fixed end of the first driving device 3 is fixedly installed on the table base 1, and the movable end is connected to the side of the working platform 2, driving the working platform 2 to slide in the first direction on the horizontal plane. It should be noted that the first direction refers to the direction in which the movable end of the first driving device 3 moves in a straight line.

[0030] Furthermore, the working platform 2 includes a front workbench surface 21, a rear workbench surface 22, and a lifting workbench surface 23 distributed in the front-to-back direction. As Figure 1 shown, the lifting workbench surface 23 is located between the front workbench surface 21 and the rear workbench surface 22. Taking the fixed end of the first driving device 3 as a reference, the front workbench surface 21 is far from the fixed end of the first driving device 3, and the rear workbench surface 22 is close to the fixed end of the first driving device 3. The first driving device 3 can push the entire working platform 2, including the front workbench surface 21, the rear workbench surface 22, and the lifting workbench surface 23, to move back and forth.

[0031] Even further, within the gap between the front workbench surface 21 and the rear workbench surface 22, a plurality of identical lifting workbench surfaces 23 can be evenly distributed in the second direction, that is, the direction perpendicular to the first direction. This can enable the entire working platform 2 to have more positions for creating clearance pits for the horizontal drill 9. According to actual processing needs, control the corresponding lifting workbench surface 23 to descend to achieve clearance, and restore the flatness of the entire workbench surface after the horizontal drill 9 is used up.

[0032] As Figure 1 and Figure 2 shown, this embodiment provides a lifting workbench with two lifting workbench surfaces 23. Specifically, a plurality of second driving devices 5 for driving the lifting workbench surface 23 to move up and down are installed on the bottom surface of the lifting workbench surface 23. Among them, the fixed end of the second driving device 5 is installed on the working platform 2, and the movable end is connected to the bottom surface of the lifting workbench surface 23. It can be understood that when the number of the second driving devices 5 is one, the movable end of the second driving device 5 is connected to the position of the center point of the bottom surface of the lifting workbench surface 23. When the number of the second driving devices 5 is two, the two second driving devices 5 are symmetrically distributed on the bottom surface of the lifting workbench surface 23 along the symmetry axis perpendicular to the length direction of the lifting workbench surface 23, so that the lifting workbench surface 23 is evenly stressed. In this embodiment, it is exemplified that two second driving devices 5 are installed on each lifting workbench surface 23.

[0033] Since there are two independent second driving devices 5, in order to prevent the second driving devices 5 from failing to lift the lifting workbench surface 23 synchronously, a synchronous balancing structure 6 is required to connect the second driving devices 5 and the lifting workbench surface 23. Specifically, the synchronous balancing structure 6 includes a balance arm 62 and a balance rod 61. The length of the balance rod 61 is equal to the length of the lifting workbench surface 23, and the balance rod 61 is assembled parallel to the bottom of the lifting workbench surface 23. Both ends of the balance rod 61 are installed with balance arms 62 through bearings, and the balance arms 62 can rotate around the balance rod 61. Installation holes are provided at both ends of the balance arm 62. One end thereof is connected to the balance rod 61, and the other end is hinged to the work platform 2. As Figure 3 described, the work platform 2 is provided with a mounting base for mounting the second driving device 5, and one end of the balance arm 62 connected to the work platform 2 is hinged to the side surface of the mounting base.

[0034] More specifically, when the two second driving devices 5 rise, the second driving devices 5 will first lift the balance rod 61. At this time, the balance arm 62 rotates, and then the balance rod 61 raises the lifting workbench surface 23. The synchronous balancing structure 6 is used to evenly apply the unbalanced force to the bottom surface of the lifting workbench surface 23, so that the lifting workbench surface 23 can be lifted smoothly. If the synchronous balancing structure 6 is not used, when the second driving devices 5 rise asynchronously, the lifting workbench surface 23 will tend to one side due to unbalanced force, resulting in uneven positions on the workbench surface and affecting the processing accuracy of the plate 10.

[0035] In order to enable the work platform 2 to move linearly along the table base 1 smoothly, slide rails 42 are installed on the bottom surface of the work platform 2, and sliders 41 matching the slide rails 42 are installed at corresponding positions on the table base 1. When the work platform 2 is assembled on the table base 1, under the action of the first driving device 3, the work platform 2 is pushed to move along the direction of the slide rails 42 to ensure that the work platform 2 can move linearly. It can be understood that the slide rails 42 can be installed on the bottom surface of the work platform 2 and the sliders 41 can be installed on the top surface of the table base 1, or the installation positions of the sliders 41 and the slide rails 42 can be reversed, that is, the sliders 41 are installed on the bottom surface of the work platform 2 and the slide rails 42 are installed on the top surface of the table base 1.

[0036] In this embodiment, both the first driving device 3 and the second driving device 5 are cylinders. Among them, the first driving device 3 is a two-stage cylinder, which can drive the work platform 2 to run two distances. In addition to using cylinder drive, a motor can also be used in cooperation with a lead screw and a lead screw seat to drive the work platform 2 and the lifting workbench surface 23 to move linearly.

[0037] In order to increase the height of the table base 1 and improve the installation stability, feet 7 are added to the bottom of the table base 1 to fix the table base 1 to the bottom surface. Specifically, several installation holes are provided at the bottom of the feet 7 for installing screws to firmly fix the table base 1 to the ground.

[0038] More specifically, the movable lifting workbench further includes a fixed workbench 8 and a drill bit. The drill bit includes a horizontal drill 9, an upper drill head 91 and a lower drill head 92. The upper drill head 91 and the lower drill head 92 are used for machining the horizontal plane of the plate. Specifically, the tabletop height of the fixed workbench 8 is the same as that of the lifting workbench. The fixed workbench 8 is arranged opposite to the lifting workbench, and their length directions are parallel. The first driving device 3 can drive the work platform 2 to approach or move away from the fixed workbench 8. In this embodiment, two lifting workbench surfaces 23 are configured, and the length of each lifting workbench surface 23 is 600 mm to illustrate the actual production process.

[0039] Specifically, as Figure 5 shown, taking the illustrated direction as the reference, the plate 10 is placed on the left side, and the length of the plate 10 is 600 mm, which is the same as the length of the lifting workbench surface 23. When horizontal drilling holes are to be made on both the left and right sides of the plate 10, since there is no workbench surface blocking on the left side of the plate 10, the horizontal drill 9 can drill holes normally without the need for an avoidance pit. When drilling holes on the right side surface of the plate 10, since there is a workbench surface on the right side, the horizontal drill 9 needs an avoidance pit. At this time, the right lifting workbench surface 23 is controlled to descend to avoid the horizontal drill 9. Similarly, when the length of the plate 10 is less than 600 mm, the left lifting workbench surface 23 needs to be controlled to descend for avoidance. When the length of the plate 10 is greater than or equal to 600 mm and less than 1200 mm, the right lifting workbench surface 23 needs to be controlled to descend for avoidance.

[0040] It can be understood that the length of the lifting workbench surface 23 can be adjusted adaptively according to the needs of actual production. When two adjacent sides of the plate are located at the edge of the workbench surface, when horizontal drilling is to be performed on the side surfaces of these two adjacent sides, there is no need to adjust the lifting workbench surface 23 to create an avoidance pit.

[0041] When milling grooves on the upper surface of the plate 10, the bottom of the plate 10 needs complete support at this time to ensure uniform stress on the plate 10. Therefore, it is necessary to control the first driving device 3 to turn on the two-stage cylinder gear and drive the work platform 2 to make the front workbench surface 21 fit with the fixed tabletop, so that the entire workbench surface forms a complete tabletop to support the plate.

[0042] When vertical drilling is to be performed on the plate 10 or milling grooves on the lower surface of the plate 10, it is necessary to control the first driving device 3 to turn on the one-stage cylinder gear. At this time, there is a certain gap between the front workbench surface 21 and the fixed workbench 8 for avoiding the vertical upper drill head 91 or lower drill head 92. At the same time, there is a pressure wheel on the top surface of the plate 10 to apply pressure to it to ensure that the plate 10 is not lifted during processing.

[0043] As Figure 5As shown, when horizontal drilling is required on the front side of the plate 10, it is necessary to control the first driving device 3 to open a certain cylinder gear position, so that the front workbench surface 21 moves away from the fixed workbench 8. At this time, there is a certain gap between the front workbench surface 21 and the fixed workbench 8 to clear the horizontal drill 9.

[0044] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
