Description

Technical Field

[0001] This utility model relates to the field of planar cutting equipment technology, and in particular to a worktable for a planar cutting machine with better stability. Background Technology

[0002] A flat surface cutting machine is a mechanical device used for cutting flat materials. The structure of an existing flat surface cutting machine may include a main body, a movable laser cutting head, and a worktable for placing the sheet material. The specific structure of the worktable is shown in the accompanying drawings. Figure 1 As shown, the device includes a support frame 1 fixedly connected to the main body of the equipment and several serrated support bars 2 evenly spaced. Profiles 3 are provided on both sides of the support frame 1. The profiles 3 have slots 301 for the two ends of the support bars 2 to be snapped together. A limiting cover plate 201 is fixedly provided on the support frame 1 to prevent the support bars 2 from disengaging from the slots 301. Several assembly holes for fasteners 6 to pass through are provided on the limiting cover plate 201 at intervals. The limiting cover plate 201 is connected to the support frame 1 through the assembly holes.

[0003] Combining the above schemes and Figure 1 As shown, there is a certain gap between the support bar and the limiting cover plate, and the support bar is in a state of being mounted in the slot. This is because the vibration generated when the laser flatbed cutting machine cuts the material is small, and the impact on the support bar is small. As a result, the vibration amplitude of the support bar is small. In low-to-medium precision cutting, the dimensional deviation caused by this vibration will fall within the tolerance range of the material and will not have a significant impact on the final size of the material. However, in high-precision processing, the dimensional deviation caused by this slight vibration can easily exceed the tolerance range of the material, resulting in dimensional defects. Therefore, the current method of setting the support bar on the worktable of the laser flatbed cutting machine has a certain degree of vibration during operation. Its stability is only suitable for low-to-medium precision processing and is not suitable for high-precision processing. Utility Model Content

[0004] In view of the shortcomings of the existing ones, the purpose of this utility model is to provide a flat cutting machine worktable that is less prone to vibration after installation and has better stability.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A more stable worktable for a flat cutting machine includes a support frame and a number of support bars that are snapped into and distributed at intervals along the support frame. Limiting mechanisms are provided on both sides of the support frame. The limiting mechanisms include a pushing component that is movably disposed on one side of the support frame and drives the support bars to move closer to the other side of the support frame when it is moved, and an abutting component disposed on the other side of the support frame for the support bars to move closer to and abut against.

[0007] By adopting the above solution, the pushing component in this solution can drive the support bar to move to the other side of the support frame when it is in motion, and cooperate with the abutting component to clamp the support bar. The squeezing force from both sides of the support bar limits the amplitude of the support bar's vibration, thereby improving stability and reducing the instability of material dimensional deviation caused by the vibration of the support bar during laser cutting, thus reducing the probability of producing defective products.

[0008] Preferably, a cooperating structure is provided between the pushing component and the support bar, which drives the support bar to move to the other side when the pushing component moves. The support bar is restricted from moving upward after it comes into contact with the pushing component and the abutting component on both sides.

[0009] Preferably, the two sides of the support frame are fixedly provided with profiles with several slots, and the two ends of the support strip are respectively inserted into the slots and mounted on the profiles.

[0010] Preferably, the pushing component is raised and lowered relative to the profile, and the cooperating structure includes a guide slope formed on the pushing component that abuts against the support bar and pushes the support bar to move when it descends. The end of the support bar is formed with a chamfer that serves as a transition when it contacts the guide slope.

[0011] Preferably, the abutment component is fixedly installed relative to the profile, and a limiting groove is formed on the abutment component for the support bar to abut against and restrict the support bar from vertically disengaging from the slot, and the end of the support bar fits the shape of the limiting groove.

[0012] Preferably, the abutment component and the profile are connected by fasteners, and the profile has mounting positions for the fasteners to pass through.

[0013] Using the above solution, when the pushing component descends, the friction generated by the contact between the guide ramp and the beveled corner of the support bar can drive the support bar to move towards the abutting component. When the support bar abuts the abutting component, the end of the support bar will conform to the shape of the limiting groove, and the cup limiting groove restricts upward movement. At the same time, the other side is abutted by the guide ramp of the pushing component and cannot move upward. Compared with the previous solution, this solution adds a structure to restrict the upward movement of the support bar, making it less likely for the support bar to detach from the cooperation between the pushing component and the abutting component.

[0014] Preferably, a lifting assembly is provided between the pushing component and the profile to allow the pushing component to move up and down.

[0015] Preferably, the lifting assembly includes a connector arranged along the lifting direction of the pushing component. The connector is screwed onto the profile. The pushing component has a guide groove laterally opened in the lifting direction relative to itself. The end of the connector is formed with a connection end that connects to the pushing component after sliding into the guide groove.

[0016] Using the above scheme, when the pushing component is not in contact with the support bar, the profile is hung on the connecting end of the connector by the guide groove. The lifting position of the pushing component is changed by the depth of the connector being screwed into the profile. When the pushing component is in contact with the support bar, the cooperation relationship between the connector and the pushing component changes to the connector in contact with the support bar. The support bar is driven to move towards the contact component by the action of the connector being screwed into the profile.

[0017] Preferably, the connector is located in the center of the pushing member, and a balancing component is provided between the pushing member and the profile to balance the pressure on both sides of the pushing member when the connector drives the pushing member to press down.

[0018] Preferably, the balancing assembly includes a top support member located between the pushing member and the profile and distributed on both sides of the connector. The top support member and the connector are arranged in the same direction and the ends abut against the pushing member. The top support member and the profile are screwed together.

[0019] With the above solution, since the pushing component is a long strip component set along the profile, setting only a connector in the middle of the pushing component will result in the two ends of the pushing component lacking support. The top support component in this solution can support the two ends of the pushing component, making the overall force more even.

[0020] This utility model has significant technical effects due to the adoption of the above technical solutions: When the pushing component in this solution is active, it can drive the support bar to move to the other side of the support frame and cooperate with the abutting component to clamp the support bar. The squeezing force from both sides of the support bar limits the amplitude of the support bar's vibration, thereby improving stability and reducing the instability of material dimensional deviation caused by the vibration of the support bar during laser cutting, thus reducing the probability of producing unqualified products.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0033] Example

[0034] A more stable worktable for a flatbed cutting machine, based on Figure 1 As shown, it includes a support frame 1 and several spaced support bars 2. Profiles 3 are symmetrically arranged on both sides of the inner ring of the support frame 1. Several slots 301 are opened on the profiles 3. The two ends of the support bars 2 can be respectively inserted into the slots 301. The whole is mounted on the profiles 3. The above is the prior art, and will not be described in detail in this embodiment.

[0035] The improvement in this embodiment is that limit mechanisms are provided on both sides of the support frame 1, according to... Figure 4 , 6As shown, the limiting mechanism includes a pushing component 4 located on one side of the support frame 1. The pushing component 4 can move up and down relative to the profile 3. A guide slope 401 is formed on the pushing component 4. When the pushing component 4 descends, it abuts against the support bar 2 and drives it to move to the other side of the support frame 1. The end of the support bar 2 is formed with a chamfer 202 that can fit with the guide slope 401. When the guide slope 401 abuts against the support bar 2, the contact between the chamfer 202 and the guide slope 401 plays a transition role.

[0036] according to Figure 5 , 7 As shown, the limiting mechanism also includes an abutment component 5 located on the other side of the support frame 1. When the support bar 2 is driven to move by the pushing component 4, it will approach the abutment component 5. The abutment component 5 has a limiting groove 5021 formed on it for the support bar 2 to approach and abut against it. The limiting groove 5021 can limit the support bar 2 from vertically disengaging from the slot 301. The end of the support bar 2 fits the shape of the limiting groove 5021. The abutment component 5 is fixedly installed with the profile 3. Figure 5 As shown, in this embodiment, the abutment component 5 is divided into a mounting base 501 and an elastic abutment block 502. The limiting groove 5021 is opened on the elastic abutment block 502, and its shape is a horizontal V-shape. The elastic abutment block 502 is made of rubber. When the support bar 2 abuts against the elastic abutment block 502, the rubber material will generate a certain deformation to offset the stress of the support bar 2. The abutment component 5 is connected to the profile 3 by a fastener 6. The profile 3 is provided with a mounting position 302 for the fastener 6 to pass through and connect with the abutment component 5. In this embodiment, the fastener 6 is a bolt, and the mounting position 302 is a mounting groove with an opening opened on the profile 3. The fastener 6 can slide into the mounting groove along the opening of the mounting groove. During subsequent adjustment, the fastener 6 can slide along the mounting groove until the side wall of the abutment component 5 abuts against the support frame 1.

[0037] The lifting and lowering movement of the pushing component 4 is achieved by a lifting assembly located between the pushing component 4 and the profile 3. Figure 4 , 6 As shown, the lifting assembly includes a connector 7 screwed onto the profile 3. The axis of the connector 7 is distributed along the lifting direction of the top support 8. The profile 3 has a first threaded hole 303 for the connector 7 to connect to. The pushing component 4 has a guide groove 402. The guide groove 402 is opened laterally along the lifting direction of the pushing component 4 relative to its own lifting direction. The end of the connector 7 has a connecting end 701 that can slide into the guide groove 402. In this embodiment, the pushing component 4 is hung on the connector 7 by the cooperation of the guide groove 402 and the connecting end 701. The side of the pushing component 4 abuts against the support frame 1. When the connector 7 rotates in the first threaded hole 303, it can drive the pushing component 4 to move up or down.

[0038] according to Figure 9 , 10 As shown, the connector 7 is located in the center of the pushing component 4. A balancing assembly is provided between the pushing component 4 and the profile 3. The balancing assembly includes top-holding members 8 distributed on both sides of the connector 7. The axis of the top-holding members 8 is arranged in the same direction as the axis of the connector 7. One end of the top-holding member 8 is screwed onto the profile 3. The profile 3 has a second threaded hole 304 for screwing the top-holding member 8. The end of the top-holding member 8 abuts against the pushing component 4. Figure 9 , 10 As shown, in this embodiment, the top of the pushing component 4 is provided with a horizontal clearance groove 403 connecting both ends, and the top holding component 8 abuts against the bottom of the clearance groove 403.

[0039] Based on the above structure, refer to Figures 1-10 It can be seen that the assembly process of a planar cutting machine worktable with higher installation precision in this embodiment is as follows:

[0040] The first step is to assemble the profile 3 and the limiting mechanism. First, divide the profile 3 into two parts. One part is used to install the pushing component 4, and the other part is used to install the abutting component 5. When installing the pushing component 4, first screw the connector 7 into the first threaded hole 303. Then, align the guide groove 402 on the pushing component 4 with the connecting end 701 and guide it into place. Then, rotate the pushing component 4 until its side wall is flush with the profile 3. Then, screw the connector 7 to drive the pushing component 4 to abut against the inner wall of the profile 3. Then, screw the top support 8 into the second threaded hole 304 and screw it until the end of the top support 8 abuts against the bottom of the relief groove 403. At this point, the profile 3 and the pushing component 4 are pre-assembled. When installing the abutting component 5, first screw the fastener 6 into the abutting component 5 and keep a sufficient gap between the large end of the fastener 6 and the abutting component 5. Next, align the fastener 6 with the opening of the mounting groove and snap it in. Then, pre-tighten the fastener 6. At this point, the profile 3 and the abutting component 5 are pre-assembled.

[0041] The second step is to connect the profile 3 to the support frame 1. The profile 3 equipped with the pushing part 4 and the abutting part 5 are welded to the inner walls on both sides of the support frame 1 respectively. Then, the fasteners 6 are loosened, the abutting part 5 is adjusted to fit the side wall of the mounting base 501 against the support frame 1, and then the fasteners 6 are tightened.

[0042] The third step is to insert the support bars 2 one by one into the slots 301. When inserting, the end of the support bar 2 that is close to the pushing component 4 can be tilted slightly downward and inserted into the slot 301 on the side with the pushing component 4. Then, the support bar 2 is laid flat so that the other side is inserted into the slot 301. This is to prevent the support bar 2 from being inserted vertically downward, which would cause the two ends of the support bar 2 to collide or scratch with the pushing component 4 and the abutting component 5.

[0043] The fourth step is to adjust the limiting mechanism to lock the support legs. After all the support legs are installed in the slots 301, the connecting bracket is gradually screwed into the first threaded hole 303, driving the pushing component 4 to descend and gradually pushing the support bar 2 towards the abutting component 5. When the pushing component 4 can no longer descend, stop screwing. Then, screw the top holding parts 8 on both sides into the second threaded hole 304 until they just abut against the bottom of the clearance groove 403. This completes the assembly process of a more stable flat cutting machine workbench in this embodiment. Afterward, it is only necessary to hoist the pre-assembled workbench onto the main body of the equipment for fixation.

[0044] Based on the above installation process, it can be seen that the pushing component 4 in this solution can drive the support bar 2 to move to the other side of the support frame 1 when it is in motion, and cooperate with the abutting component 5 to clamp the support bar 2. The squeezing force from both sides of the support bar 2 limits the amplitude of the vibration of the support bar 2, thereby improving stability and reducing the instability of material dimensional deviation caused by the vibration of the support bar 2 during laser cutting, thus reducing the probability of producing unqualified products.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
