Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing equipment and relates to a dustproof engraving machine. Background Art

[0002] An engraving machine refers to a device that can mark the surface of an object with a certain depth. In terms of processing principles, it is a combination of drilling and milling. It has a wide range of applications and many models. It can be applied to the processing and engraving of wood, stone, metal, plastic, etc., laying the foundation for the large-scale and rapid production of engraved products.

[0003] For example, Chinese patent [application number: 201620004272.3] discloses a new type of wood engraving machine, including an operating body, a gantry is provided on the operating body, an engraving head is installed on the gantry, the engraving head includes a milling cutter and a rotating saw blade, a wood rotating clamp device is also provided at the upper left end of the operating body, the wood rotating clamp device includes a base, a fixed end device is provided on the base, the fixed end device is connected to a transmission mechanism, a guide rail is provided on the base, and a controller is also provided on the upper right side of the operating body.

[0004] At present, the structure of the common engraving machine on the market is similar to the engraving machine structure disclosed in the above patent document. As we all know, in the process of existing engraving machine processing, a large amount of chips and dust are often generated. However, in this field, the analysis of the existing engraving machine structure, such as the engraving machine disclosed in the above patent document, shows that the existing engraving machine generally does not specially design dustproof structures such as dust covers for dust prevention. The reason is that the dust cover will increase the space occupied by the machine body on the one hand, and on the other hand, if the dust cover is installed, it will cause the workpiece to be taken and placed very inconvenient, especially for large engraving workpieces, the clamping and placement itself takes up a lot of time, so the obstruction and interference of the dust cover will greatly increase the extension of the workpiece taking and placing time. Therefore, those skilled in the art will not design the engraving machine to install a dust cover. The most conventional general dust prevention treatment is to use an exhaust device or cutting fluid to take away part of the dust, but these dust prevention measures have poor dust prevention effects and cannot solve the dust prevention problem well. In other words, in the prior art, the protection of the working environment is often sacrificed in exchange for the improvement of processing efficiency, and it is impossible to take into account both the improvement of dust prevention effect and processing efficiency. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the prior art and to propose a dustproof engraving machine. The present invention solves the technical problem that the dustproof effect and processing efficiency of the prior engraving machine cannot be improved at the same time.

[0006] The objective of the present invention can be achieved through the following technical solutions: A dustproof engraving machine, comprising a frame, a tool holder and a workbench for clamping a workpiece, characterized in that the dustproof engraving machine also includes a dustproof cover with a workpiece inlet and outlet, the frame, the tool holder and the workbench are all located in the dustproof cover, a guide rail is fixedly connected to the frame, the guide rail extends from the inside of the dustproof cover to the outside of the dustproof cover via the workpiece inlet and outlet, the workbench is slidably connected to the guide rail and can slide completely or partially to the outside of the dustproof cover through the workpiece inlet and outlet.

[0007] Different from the conventional design method in the prior art that sacrifices the protection of the working environment in exchange for the improvement of processing efficiency, the present engraving machine improves both the dustproof effect and the processing efficiency. Specifically, in order to improve the dustproof effect, the present engraving machine provides a dust cover on the frame, and the frame, the tool holder for processing the workpiece, and the workbench are located inside the dust cover, that is, the dust cover is provided outside the processing area, so that the processing area is blocked from the outside, so that the chips and dust are not easy to escape, which greatly improves the dustproof effect; at the same time, the present invention designs a workpiece inlet and outlet on the dust cover for the workpiece to enter and exit, and then designs a guide rail on the frame, so that the workbench for clamping the workpiece is slidably connected to the guide rail, and because the guide rail extends from the inside of the dust cover to the outside of the dust cover via the workpiece inlet and outlet, the workbench can be fully or partially moved out of the dust cover along the guide rail via the workpiece inlet and outlet. The dust cover enables the workpiece to be taken, placed and clamped outside the dust cover, so that the workpiece can be taken, placed and clamped without being affected by the dust cover, and the sliding design of the workbench also makes it possible for large workpieces to be clamped without being interfered by the tool holder and the surrounding frames, thereby improving the convenience of taking and placing the workpiece and ensuring the improvement of processing efficiency; that is, through the sliding design of the guide rails and the workbench, the problem of the inconvenience of taking and placing the workpiece caused by the above dustproof design, which affects the improvement of processing efficiency, is cleverly overcome. Therefore, through the coordinated design of the dust cover, guide rails and workbench, the engraving machine can improve the dustproof effect while improving the processing efficiency, greatly improving the application prospects of the engraving machine. In addition, it should be noted that the above-mentioned frame is located in the dust cover, which includes two situations, referring to part of the frame being located in the dust cover or the entire frame being located in the dust cover. The above-mentioned workbench can be a platform plate structure or a rectangular frame structure.

[0008] In the above-mentioned dustproof engraving machine, a support member is provided below or outside the portion of the guide rail extending out of the workpiece inlet and outlet, and the support member is fixedly connected to or integrally formed with the frame.

[0009] Preferably, the support member has a relief recess which is consistent with the extending direction of the guide rail.

[0010] Through the above support member design, on the one hand, the problem of the support strength of the guide rail is solved; on the other hand, the design of the recess on the support member can provide people with standing space. If the workbench is partially located outside the dust cover or close to the entrance or exit of the workpiece, people can stand in the recess to adjust the workpiece without waiting until the workbench returns to the extreme position, which is beneficial to improving processing efficiency.

[0011] In the dustproof engraving machine, the guide rails are two and parallel to each other, the support members are two support beams arranged below the guide rails and corresponding to the guide rails one by one, and a recess is formed between the two support beams. Through the above design, the purpose of improving processing efficiency is achieved with the simplest structure.

[0012] As another solution, in the above-mentioned dustproof engraving machine, the support member is a plate-shaped support platform.

[0013] In the above-mentioned dustproof engraving machine, a double door, door curtain or sliding door is provided at the workpiece inlet and outlet. Through the above design, when the workpiece is processed, the double door, door curtain or sliding door can block the escape of chips and dust, prevent the dust from escaping the dust cover, thereby further improving the dustproof effect of the engraving machine, and the double door, door curtain or sliding door can be pushed open when the workpiece is taken, placed or clamped, and will not affect the workpiece, so that the processing efficiency is not affected.

[0014] In the above dustproof engraving machine, the workbench slides along the guide rail under the drive of the driving device; the driving device is a driving cylinder; or the driving device is a driving oil cylinder; or the driving device is a screw motor. The driving cylinder or the driving oil cylinder can fix the piston rod to the workbench to drive the workbench to slide; the screw motor can cooperate with the screw by fixing the nut on the workbench, so that the screw motor can drive the workbench to slide.

[0015] In the above dustproof engraving machine, the dustproof cover or the double-door or the sliding door is provided with an observation window. Through the above design, it is convenient for people to monitor the processing status of the workpiece at any time.

[0016] According to the different movement modes in three-dimensional space, in the above-mentioned dustproof engraving machine, the structure of model one is as follows: the frame includes a base, a gantry beam capable of moving horizontally longitudinally is slidably connected to the base, a horizontal support plate capable of moving horizontally transversely is slidably connected to the gantry beam, a mounting frame capable of moving vertically is slidably connected to the horizontal support plate, the tool holder is in an elongated strip shape and has a plurality of tool heads, and the tool holder is fixedly or rotatably connected to the mounting frame.

[0017] In the above-mentioned dustproof engraving machine, the structure of model 2 is as follows: the frame includes a base, a gantry beam that can move horizontally and longitudinally is slidably connected to the base, a vertical support plate that can move vertically is slidably connected to the gantry beam, a mounting frame that can move horizontally and transversely is slidably connected to the vertical support plate, the tool holder is long and has a plurality of tool heads, and the tool holder is fixedly or rotatably connected to the mounting frame.

[0018] In the above-mentioned dustproof engraving machine, the structure of model three is as follows: the frame includes a base and a gantry frame arranged on the base and capable of moving horizontally longitudinally, the gantry frame includes two columns corresponding to the two sides of the base and slidably connected, the two columns are slidably connected with a bracket beam that can move vertically, the bracket beam is slidably connected with a mounting frame that can move horizontally laterally, the tool holder is long and has a plurality of tool heads, and the tool holder is fixedly or rotatably connected to the mounting frame.

[0019] When the tool holder is fixed on the mounting frame, the engraving machine is a five-axis engraving machine, and when the tool holder is rotatably connected to the mounting frame, the engraving machine is a six-axis engraving machine.

[0020] In the dustproof engraving machines of the above-mentioned models one to three, a clamping device is provided on the workbench, and the above-mentioned clamping device includes a long strip-shaped work clamp fixedly or rotatably connected to the workbench, and a plurality of positioning components for positioning the workpiece are provided on the work clamp. The work clamp is arranged parallel to the tool holder, and clamping members are provided on the workbench, the number of which is the same as that of the positioning components and the positions are opposite. The work clamp can be transformed between a first position and a second position. When the work clamp is in the second position, the positioning component cooperates with the clamping member to clamp the workpiece. When the work clamp is connected to the workbench, the work clamp can be swung back and forth or rotated with the strip direction of the work clamp as the axis to change the first position and the second position. In the first position, the short workpiece can be directly fixed on the work clamp through the positioning assembly, and the parallel work clamp and the tool holder can form a sufficient angle for engraving, and when processing thick and long workpieces, the work clamp can be changed to the second position, and the thick and long workpiece can be clamped in the horizontal direction with the support. In this way, the multi-tool head of the engraving machine can be applied to both short and long workpieces, and has a very wide range of applications. It overcomes the practice that the general multi-tool head engraving machine can only place workpieces horizontally, and improves the processing efficiency.

[0021] As another solution, in the dustproof engraving machines of the above-mentioned models 4 and 5, a fixture mounting plate capable of horizontally moving is slidably connected to the workbench, and the fixture mounting plate is provided with a clamping device, which includes a long strip-shaped work clamp fixedly connected to the fixture mounting plate, and a plurality of positioning components for positioning the workpiece are provided on the work clamp, the work clamp is arranged in parallel with the tool holder, and a clamping member that can be the same in number and opposite in position as the positioning components is provided on the workbench, and the work clamp can be transformed between a first position and a second position, and when the work clamp is in the second position, the positioning component cooperates with the clamping member to clamp the workpiece. The clamping devices in models 4 and 5 are the same except that the mounting base structure of the fixture mounting plate and the workbench is different, that is, the workbench in the clamping devices in models 4 and 5 is rotatably connected to the fixture mounting plate, and the other structures and clamping and positioning principles are the same.

[0022] In the above three types of machines, the sliding parts such as the gantry beam, horizontal support plate, vertical support plate, gantry frame, bracket beam, mounting frame, fixture mounting plate, etc. can all slide by means of the cooperation of slide rails and sliders, and the above sliding parts can all be driven to slide by driving parts such as cylinders, oil cylinders, and motors.

[0023] In the above-mentioned dustproof engraving machine, when the tool holder is rotatably connected to the mounting frame, a driving motor is fixed in the middle of the mounting frame, and the driving motor can drive the tool holder to swing with its strip direction as the axis. A plurality of the tool heads are arranged at intervals on the tool holder, and the tool heads at the same location have at least two different directions. As another arrangement mode of the tool holder driving motor, one end of the tool holder is provided with a driving motor that can drive the tool holder to swing with its strip direction as the axis. The tool heads at the same location with different directions form a group of tool head groups, which are used to engrave the same workpiece. There are several groups of these engraving tool groups and they are arranged in sequence on the tool holder. Generally, the number of engraving tool groups is determined according to the number of positioning components. The tool heads with different directions can select the required tool heads by swinging the tool holder, and the tool change engraving is performed, which improves the efficiency. And the tool heads with different directions can select two tool heads with opposite directions, or four tool heads with a difference of 90 degrees in four directions of up, down, front and back. When one tool head is engraving, the other tool heads will not interfere with the movement and swing of the workpiece, thereby improving the scope of application and processing efficiency.

[0024] Preferably, in the dustproof engraving machine, a collecting trough is provided in the frame, one end of the collecting trough has a discharge port, a discharge screw is provided in the collecting trough, and the discharge screw can rotate under the drive of a rotary motor. The discharge screw in the collecting trough rotates under the action of the driving motor, thereby generating a thrust along the axial direction of the discharge screw on the waste material, so that the waste material moves along the length direction of the collecting trough and leaves the collecting trough from the discharge port of the collecting trough. The staff only needs to place a container for accommodating the waste material at the discharge port of the collecting trough, and there is no need to manually clean the collecting trough, which is simple and convenient.

[0025] Compared with the existing technology, this dustproof engraving machine has the following advantages:

[0026] 1. This dustproof engraving machine not only has excellent dustproof function through the coordinated design of dustproof cover, guide rail and workbench, but also makes it easy to take and place workpieces, and significantly improves processing efficiency.

[0027] 2. The dustproof engraving machine is equipped with a swinging worktable and a rotating positioning component design, which enables the engraving machine to be suitable for processing short and small workpieces as well as thick and long workpieces, and has a very wide range of applications.

[0028] 3. This dustproof engraving machine is equipped with a tool holder and tool head design. The tool heads in different directions can be selected by swinging the tool holder to change the tool for engraving, which improves efficiency. When one tool head is engraving, the other tool heads will not interfere with the movement and swing of the workpiece, so that the swing angle of the workpiece can be increased, the application range of a single tool head is increased, and the processing efficiency is improved.

[0044] Embodiment 1:

[0045] Specifically, if Figure 1 and Figure 2As shown, the dustproof engraving machine includes a frame 1, a tool holder 2 and a workbench 3 for clamping a workpiece. The frame 1 is provided with a dust cover 4 having a workpiece inlet and outlet 41. Part or all of the frame 1, the tool holder 2, and the workbench 3 are located in the dust cover 4. A guide rail 5 is fixedly connected to the frame 1. The guide rail 5 extends from the inside of the dust cover 4 to the outside of the dust cover 4 through the workpiece inlet and outlet 41. The workbench 3 is slidably connected to the guide rail 5 and can slide completely or partially to the outside of the dust cover 4 through the workpiece inlet and outlet 41. A support member 6 is provided below or outside the portion of the guide rail 5 extending out of the workpiece inlet and outlet 41. The support member 6 is fixedly connected to the frame 1 or integrally formed therewith. The support member 6 has a clearance recess 61 that is consistent with the extension direction of the guide rail 5. More specifically, as Figure 3 The guide rails 5 shown in the figure have two parallel guide rails, and the support members 6 are two support beams arranged below the guide rails 5 and corresponding to the guide rails 5 one by one, and a clearance notch 61 is formed between the two support beams. Fig. 9 , Fig.10 and Fig.11 As shown, the workpiece inlet and outlet 41 of the dustproof engraving machine is provided with a double door 18 or a door curtain 19 or a sliding door 20.

The clamping device includes a long strip work clamp 14 fixedly or rotatably connected to the workbench 3, and a plurality of positioning components 141 for positioning the workpiece are arranged on the work clamp 14. The work clamp 14 is arranged in parallel with the tool holder 2, and a clamping member 15 having the same number and opposite position as the positioning components 141 is arranged on the workbench 3. The work clamp 14 can be changed between a first position and a second position. When the work clamp 14 is in the second position, the positioning components 141 cooperate with the clamping member 15 to clamp the workpiece. In actual production, the above-mentioned support seat 1b may not be designed as required, and the gantry beam 7 is directly connected to the seat body in a sliding manner.

[0047] More specifically, in this embodiment, the clamping member 15 is a tip 151, which is slidably connected to a tip rack 152 on the workbench 3 and is capable of approaching or moving away from the work clamp 14 and is in the shape of an elongated strip. The tip 151 is arranged on the tip rack 152, and a locking structure is provided between the tip rack 152 and the work clamp 14 to fix the tip rack 152 after it slides. The tip rack 152 drives all the tips 151 to move together, which can improve the clamping efficiency. The outer end of the tip 151 is a spike structure, which can be a single conical spike or a disc-shaped structure with multiple spikes. The tip 151 is slidably connected to the tip rack 152, and the outer end of the tip 151 is driven to extend through a handle or a cylinder to cooperate with the above-mentioned work clamp 14 to form a support. The handle drives the tip 151 to extend outward, and a transmission structure such as a thread or a gear rack can be used.

[0048] As another solution, the clamping member 15 includes a top seat and a top 151 arranged on the top seat, each top seat is slidably connected to the workbench 3, and a locking structure is provided between each top seat and the work clamp 14 to fix the top 151 after it slides.
