Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a processing positioning structure of a laser cutting workbench. Background Art

[0002] To facilitate loading and unloading and avoid interference between the sheet metal and the laser cutting head, some laser cutting machines have a single pull-out worktable. This means that when loading and unloading, the worktable is pulled forward, away from the processing area of ​​the chassis. During processing, the worktable is pushed backward to a set position and its movement is restricted by a processing positioning structure to prevent vibration and affect processing accuracy. Existing processing positioning structures primarily use cylinders to drive pins that are inserted into sockets on the worktable to restrict movement. This type of processing positioning structure not only requires the supply of compressed air, which consumes energy, but also requires the layout of an additional air supply pipe, resulting in high initial manufacturing costs and subsequent maintenance costs.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a processing positioning structure, which is intended to manually control the quick clamp to limit the movement of the workbench and ensure that the workbench does not shake during operation.

DETAILED DESCRIPTION

[0021] The present invention provides a processing positioning structure for a laser cutting worktable. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0022] See also Figure 1-Figure 5 The utility model provides a processing and positioning structure of a laser cutting workbench, including a base frame 1, a pull-out workbench 2 slidably arranged on the base frame 1, the base frame 1 is provided with an anti-collision limiter 3 located behind the pull-out workbench 2, a support 41 located in front of the pull-out workbench 2, and a quick clamp 42 arranged on the support 41, and the pull-out workbench 2 is provided with a clamping piece 5 cooperating with the quick clamp 42 at the bottom of the front end. By pressing the handle of the quick clamp 42, the clamp head on the pressure arm of the quick clamp 42 is pressed toward the clamping piece 5, so that the rear end of the pull-out workbench 2 is close to the anti-collision limiter 3.

[0023] When the pull-out workbench 2 needs to be moved out of the processing position for loading and unloading operations, the operator can easily pull it forward to leave the processing area. After completing the loading and unloading, the operator pushes the pull-out workbench 2 back to the processing position so that its rear end is close to the anti-collision limiter 3 to ensure that the workbench is in the precise position required for processing. Next, the operator presses the handle of the quick clamp 42 to swing the clamp head on the pressure arm backward and press the clamping piece 5, thereby further fixing the position of the pull-out workbench 2. This manual operation method does not require an external power source (such as compressed air), reduces energy consumption and simplifies the system structure. During the processing, the quick clamp 42 maintains the stability of the workbench to prevent it from moving due to vibration or external force, ensuring processing accuracy. After the processing is completed, release the handle of the quick clamp 42 to release the clamp head from the clamping piece 5, and then the workbench can be easily pulled forward for the next loading and unloading operation.

[0024] Compared to existing technologies, the machining positioning structure provided by the present invention utilizes a manual quick-action clamp 42 in place of a traditional cylinder-driven latch. This eliminates the need for compressed air, which consumes energy, and eliminates the need for additional air supply lines, reducing both the initial investment cost and subsequent maintenance costs of the equipment. The quick-action clamp 42 is simple and quick to operate; simply pressing the handle allows for rapid positioning and securing of the pull-out worktable 2, improving work efficiency. The anti-collision limiter 3 and quick-action clamp 42 work together to stabilize the pull-out worktable 2 during machining, enhancing machining accuracy.

[0025] Specifically, the support 41 is a first L-shaped seat, and two first waist-shaped holes 43 extending in the front-to-back direction are defined on the flat plate portion of the first L-shaped seat. The base frame 1 is provided with first threaded holes 44 corresponding to the first waist-shaped holes 43. A first screw passes through the first waist-shaped holes 43 and connects with the corresponding first threaded holes 44. The design of the first waist-shaped holes 43 allows for fine-tuning of the support 41 in the front-to-back direction, allowing the operator to adjust the position of the quick clamp 42 according to actual needs to accommodate workbenches of different sizes or different processing requirements. After adjusting the position of the support 41, the support 41 can be fixed by tightening the first screw, ensuring the accurate position of the quick clamp 42, thereby ensuring the stability and processing accuracy of the workbench during processing.

[0026] In fact, the manual toggle clamp 42 is an existing tool that can be purchased directly on the market. The manual toggle clamp 42 includes a base, a connecting rod, a handle, a pressure arm, and a clamp head arranged on the pressure arm. The base, connecting rod, handle, and pressure arm form a connecting rod mechanism. A straight line is formed between the handle, the pressure arm, and the base, that is, the "dead point" position is reached, and the clamp head on the pressure arm reliably presses the clamping member 5.

[0027] Specifically, the anti-collision stopper 3 includes a second L-shaped seat 31 and an anti-collision rubber block 32 provided on the vertical plate portion of the second L-shaped seat 31. The provision of the anti-collision rubber block 32 can effectively absorb the impact force generated when the pull-out workbench 2 collides with the anti-collision stopper 3, and the pull-out workbench 2 can quickly stop moving.

[0028] Furthermore, the flat plate portion of the second L-shaped seat 31 is provided with two second waist-shaped holes 33 extending in the front-to-back direction, and the base frame 1 is provided with second threaded holes 34 corresponding to the second waist-shaped holes 33. The second screw passes through the second waist-shaped holes 33 and is connected to the corresponding second threaded holes 34. Through the design of the second waist-shaped holes 33, the position of the second L-shaped seat 31 can be fine-tuned in the front-to-back direction, which allows the operator to adjust the position of the anti-collision limiter 3 according to actual needs to adapt to workbenches of different sizes or different processing requirements. After adjusting the position of the second L-shaped seat 31, the anti-collision limiter 3 can be fixed by tightening the second screw to ensure its accurate position, thereby ensuring the stability and processing accuracy of the workbench during processing.

[0029] Specifically, the clamping member 5 includes a top panel 51, a front vertical panel 52, a left vertical panel 53 connecting the top panel 51 and the left side of the front vertical panel 52, and a right vertical panel 54 connecting the top panel 51 and the right side of the front vertical panel 52. The clamping member 5 adopts a polyhedron structure, and the top panel 51, the front vertical panel 52, the left vertical panel 53, and the right vertical panel 54 form a solid whole, thereby improving the strength and stability of the clamping member 5. The top panel 51 is welded to the bottom surface of the frame 21 of the pull-out workbench 2. The clamp head on the pressure arm of the manual toggle clamp 42 presses on the front vertical panel 52, that is, the front vertical panel 52 serves as the contact surface for the clamp head on the pressure arm of the manual toggle clamp 42, ensuring accurate fit between the clamping member 5 and the manual toggle clamp 42, thereby ensuring the stability and processing accuracy of the pull-out workbench 2 during processing.

[0030] Specifically, the base frame 1 is provided with two guide rails 61 extending in the front-to-back direction. The bottom of the pull-out workbench 2 is provided with sliders 62 that are slidably connected to the corresponding guide rails 61, allowing the pull-out workbench 2 to move smoothly back and forth. The guide rails 61 are preferably aluminum support optical axis guide rails. Aluminum support optical axis guide rails have excellent straightness and parallelism. The friction coefficient between the aluminum support optical axis guide rails and the sliders 62 is low, which reduces the resistance of the pull-out workbench 2 during movement, ensures the smoothness of the pull-out workbench 2 during forward and backward movement, and reduces the vibration and noise caused by uneven movement.

[0031] Preferably, the base frame 1 is provided with a bracket 71 located in front of the guide rail 61, and the bracket 71 is provided with a rotatable supporting wheel 72 for supporting the pull-out workbench 2. The supporting wheel 72 can help share the weight of the pull-out workbench 2, reduce the load of the pull-out workbench 2 on the guide rail 61, ensure that the workbench is smooth and without shaking during movement, and improve stability during processing.

[0032] Preferably, the pull-out workbench 2 includes a frame 21, multiple racks 22 spaced across the frame 21, and a handle 23 at the front end of the frame 21. The multiple racks 22 spaced across the frame 21 evenly distribute the weight of the plates placed on the workbench, thereby increasing the workbench's load-bearing capacity. The handle 23 at the front end of the frame 21 allows the operator to easily pull or push the pull-out workbench 2, facilitating loading and unloading operations.
