Description

Technical Field

[0001] The invention relates to a working table of a cutting machine, in particular to a working table of a numerical control cutting machine, belonging to the technical field of numerical control processing equipment. Background Art

[0002] CNC cutting machines are all provided with a workbench for carrying workpieces (plates). Existing CNC cutting machines are all provided with serrated support bars. When the CNC cutting machine cuts the workpiece, the serrated support bars on the workbench are used to support the workpiece to achieve the cutting operation of the workpiece. Although the existing workbench structure can achieve conventional cutting operations, when the cutting point happens to fall on the support point on the serrated support bar, the ablation of the support point will greatly affect the quality of the plate. At the same time, the sharp saw teeth in the support bar will also scratch the surface of the plate during the movement of the plate, which also affects the quality of the plate. In addition, the cutting point of the existing cutting machine moves back and forth when it is working, which causes a large amount of dust to be produced during the cutting process. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a CNC cutting machine workbench with a sawtooth-free support bar which can avoid ablation of a plate caused by cutting and scratches on the surface of a workpiece caused by a support point.

[0004] In order to solve the above technical problems, the CNC cutting machine workbench of the present invention includes a plurality of longitudinally arranged main support bars and a cutting device for cutting the plates on the main support bars. The main support bars and the cutting device are fixedly installed by a connecting frame and can move synchronously. A positioning backrest for positioning the plates is arranged above the main support bars. The positioning backrest positions the plates between the cutting device and the main support bars to form a cutting station. When the cutting device cuts the plates positioned by the positioning backrest, the main support bars can move synchronously with the cutting device in the X-axis and / or Y-axis directions.

[0005] The main support bar is provided with a rolling support point that enables the main support bar to slide relative to the plate during the cutting process of the cutting device. The support bar can be driven in the X-axis and / or Y-axis direction by the longitudinal moving device and the transverse moving device.

[0006] The lateral moving device includes an X-axis slider fixedly installed at the bottom of the support bar, an X-axis rack, a lateral guide rail base arranged below the main support bar, and an X-axis movable guide rail installed on the lateral guide rail base. The lateral rack can be driven by an X-axis servo motor to enable the main support bar to move laterally with the cooperation of the X-axis movable guide rail and the X-axis slider.

[0007] The longitudinal moving device includes a Y-axis slider fixedly installed at the bottom of the transverse guide rail base, a Y-axis rack, a longitudinal guide rail base arranged below the transverse guide rail base, and a Y-axis movable guide rail installed on the longitudinal guide rail base. The Y-axis rack can be driven by a Y-axis servo motor to enable the transverse guide rail base to move longitudinally with the cooperation of the Y-axis movable guide rail and the Y-axis slider.

[0008] A processing station is arranged in front of the cutting station, and the processing station includes a jacking device and a plurality of auxiliary support bars fixedly installed on the jacking device, wherein the auxiliary support bars are staggered between the main support bars, and the auxiliary support bars can lift the plate to be processed under the drive of the jacking device.

[0009] The connecting frame is provided with a track for arranging the cutting device. The cutting device is installed on the connecting frame and can move up and down under the guidance of the track.

[0010] The connecting frame is provided with a dust recovery channel located directly below the cutting device and used for recovering dust generated during cutting.

[0011] The cutting station has two left and right positioning backrests for limiting the X-axis direction and two front and rear positioning backrests for limiting the Y-axis direction. The plate can be limited between the four positioning backrests, and the positioning backrests are driven by a backrest driving device to achieve real-time limiting of the plate.

[0012] A clamping device for shifting the plate is installed on the connecting frame, and the clamping device includes a clamping device lifting device, a clamping head installed at the bottom of the clamping device lifting device, and a clamping lifting device coordinated with the clamping head. The clamping head can be extended under the plate to be processed under the drive of the clamping device lifting device, and the clamping block on the clamping lifting device can cooperate with the clamping head to clamp and shift the plate to be processed.

[0013] The clamping head comprises an L-shaped plate body and a clamping head arranged at the end of the plate body, and the clamping head cooperates with a clamping block on a pressing and lifting device to achieve clamping of the plate.

[0014] After adopting the above structure, since the plate is positioned by the positioning backrest, and the main support bar and the cutting device are fixedly installed by the connecting frame and can be synchronously moved in the X-axis and / or Y-axis direction under the drive of the longitudinal and transverse moving device, and the plate is supported by the ball bearings on the support bar, the traditional processing method of reciprocating movement of the cutting point is completely changed, and the processing quality is greatly improved. During the processing, the problem of plate ablation caused by the cutting point falling on the saw teeth is avoided. The ball bearing support method also avoids scratches on the surface of the workpiece by the support point. In addition, the fixed cutting point makes the dust channel unique, so it also has an outstanding effect of facilitating dust removal. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The CNC cutting machine workbench of the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Embodiment 1:

[0023] As shown in the figure, the CNC cutting machine workbench of this embodiment includes three longitudinally arranged main support bars 1 and a cutting device 2 for cutting a plate 4 on the main support bars. The cutting device is preferably a laser cutting machine. The main support bars 1 and the cutting device 2 are fixedly installed through a connecting frame 3 and can move synchronously. Figure 3 It can be seen that the connecting frame is a frame structure, the main support bar 1 is installed at the bottom of the connecting frame 3, and the cutting device 2 is installed on the top of the connecting frame 3. For the installation of the cutting device, a track for placing the cutting device can be provided on the connecting frame 3. The cutting device is installed on the connecting frame 3 and can move up and down under the guidance of the track. Of course, such an installation method belongs to a conventional installation method. A positioning backer 5 for positioning the plate is provided above the main support bar 1. The positioning backer 5 positions the plate between the cutting device and the main support bar to form a cutting station. Figure 1 It can be seen that the cutting station has two left and right positioning supports for limiting the X-axis direction and two front and rear positioning supports for limiting the Y-axis direction. The plate can be limited between the four positioning supports, so that the plate can be reliably positioned, so that the cut plate is fixed, and the cutting head and the support bar at the bottom of the cutting board move at the same time to cut the plate. Figure 2It can be seen that the positioning backrests are driven by the backrest driving device to achieve real-time limiting of the plate. That is to say, when the plate needs to be positioned, the positioning backrest is moved to the cutting station under the drive of the backrest driving device. When the plate does not need to be positioned, the positioning backrest leaves the cutting station. When the cutting head of the cutting device 2 cuts the plate positioned by the positioning backrest, the main support bar can move synchronously with the cutting device in the X-axis and / or Y-axis direction. In addition, the main support bar 1 is provided with a universal ball 6 which can enable the main support bar 1 to slide relative to the plate during the cutting process of the cutting device. The plate is positioned by the positioning backrest. At this time, when the cutting head is cutting, the main support bar 1 moves so that the universal ball and the plate roll relative to each other.

[0024] Furthermore, the main support bar 1 can be driven in the X-axis and / or Y-axis direction through a longitudinal moving device and a transverse moving device. The transverse moving device includes an X-axis slider 7 fixedly installed at the bottom of the support bar, an X-axis rack 8, a transverse guide rail base 9 arranged below the main support bar, and an X-axis movable guide rail 10 installed on the transverse guide rail base. The transverse rack 8 can be driven by an X-axis servo motor 11 so that the main support bar moves laterally with the cooperation of the X-axis movable guide rail and the X-axis slider 7. The longitudinal moving device includes a Y-axis slider 12 fixedly installed at the bottom of the transverse guide rail base 9, a Y-axis rack 13, a longitudinal guide rail base 14 arranged below the transverse guide rail base 9, and a Y-axis movable guide rail 15 installed on the longitudinal guide rail base. A frame is arranged at the bottom of the transverse guide rail base 9. The Y-axis rack 13 can be driven by a Y-axis servo motor 16 so that the transverse guide rail base 9 moves longitudinally with the cooperation of the Y-axis movable guide rail and the Y-axis slider 12.

[0025] Embodiment 2:

[0026] On the basis of the first embodiment, a processing station is arranged in front of the cutting station, and the processing station includes a jacking device 17 and a plurality of auxiliary support bars 18 fixedly installed on the jacking device, the auxiliary support bars 18 are staggered between the main support bars, and the auxiliary support bars 18 can lift the plate to be processed under the drive of the jacking device. The jacking device 17 is preferably a telescopic cylinder, and the front and rear of the plurality of auxiliary support bars 18 are driven by the telescopic cylinder to achieve lifting. In addition, the Y-axis direction of the processing station is also provided with positioning backrests located on the left and right sides of the plate to be processed. During the working process, since the main support bar can move synchronously with the cutting device in the X-axis and / or Y-axis direction, the auxiliary support bar 18 is bound to interfere with the main support bar in the X-axis movement direction. At this time, after the auxiliary support bar is lifted by the telescopic cylinder, the movement trajectory of the main support bar in the X-axis movement direction is cleared, and the main support bar is moved in four directions. After the cutting is completed, the auxiliary support bar 18 falls back to its original position driven by the telescopic cylinder and is on the same horizontal plane as the main support bar. Of course, a finished product output station can also be set behind the cutting station. Figure 4It can be seen that the structure of the finished product output station is the same as that of the processing station, and will not be repeated here.

[0027] Through this structural design, a processing station is set in front of the cutting station, and a finished product output station is set behind the cutting station. Auxiliary support bars are set at both the processing station and the finished product output station, and are staggered with the main support bars of the cutting station. The auxiliary support bars in the two areas can be raised and lowered under the drive of their respective jacking mechanisms, thereby ultimately achieving reliable operation.

[0028] In addition, a clamping device for shifting the plate is installed on the connecting frame 3, and the clamping device includes a clamping device lifting device (telescopic cylinder) 20, a clamping head 21 installed at the bottom of the clamping device lifting device 20, and a clamping lifting device 22 cooperating with the clamping head 21. The clamping head 21 can be driven by the clamping device lifting device 20 to extend under the plate to be processed, and the clamping block 23 on the clamping lifting device 22 can cooperate with the clamping head 21 to tighten and shift the plate to be processed. Of course, the position of the clamping device is located between the main support strips. It is preferred to provide two sets of clamping devices, wherein the clamping head 21 includes an L-shaped plate body and a clamping head arranged at the end of the plate body. The clamping head cooperates with the clamping block 23 on the clamping lifting device 22 to clamp the plate. When in use, after the cutting is completed, the auxiliary support strip 18 is in the telescopic cylinder. After being driven to fall back to its original position and being on the same horizontal plane with the main support bar, at this time, the X-axis backrest is raised by the backrest driving device, and there is a gap between the plate to be processed and the plate after cutting at the cutting station. At the same time, the chuck and clamp lifting device 20 of the clamp head extends into this gap under the drive of the clamping block 23 on the clamping lifting device 22, and the chuck cooperates to achieve the clamping of the plate. Under the synchronous traction of the cutting device 2 and the main support bar, the plate to be processed is dragged into the cutting station. During the dragging process, the plate after cutting is forced to move to the subsequent finished product output station. Finally, after the cutting is completed, the positioning backrest of the plate is lifted up by the backrest driving device, and the clamp installed on the connecting frame is inserted into the position of the original backrest, clamping the plate to be cut and bringing it into the cutting station, and at the same time pushing the cut plate to the finished product output station.

[0029] On the basis of Example 1 or Example 2, a dust recovery channel 19 can also be provided on the connecting frame 3, which is located directly below the cutting device and is used to recover the dust generated during cutting. The dust recovery channel 19 corresponds to the cutting point of the cutting head. The dust removal pipe mouth of the dust recovery channel 19 is lower than the highest point of the rollable support point on the support bar. In this way, the dust generated by cutting is very accurately sucked into the dust removal device to avoid pollution to the environment and equipment. The main support bar 1 and the cutting device 2 in the present invention are fixedly installed through the connecting frame 3 and can move synchronously. Therefore, the cutting point is unique. This structural design provides a prerequisite for the design of the dust recovery channel 19. Therefore, dust recovery can be achieved through the designed dust recovery channel 19.
