Description

Technical Field

[0001] This utility model relates to the field of engraving machine technology, specifically to an easily adjustable engraving machine positioning component. Background Technology

[0002] According to the patent authorization announcement number: a positioning component for a plastic laser engraving machine, this utility model discloses a positioning component for a plastic laser engraving machine, relating to the field of engraving machine technology. Its key technical points are: CN215702034U includes an operating table, a support block fixedly installed on the operating table, a lead screw rotatably installed on the support block, a movable plate on the lead screw, a clamping component on the movable plate, and a protective component on the support block. The clamping component includes a collecting component and a positioning rod, which is located on the movable plate. In this positioning component for a plastic laser engraving machine, the protective component on the support block allows the clamping plate to push the positioning rod to move during clamping, causing the positioning rod to push a limiting plate to rotate clockwise. This allows the limiting plate to insert into the teeth of a limiting gear, thus limiting the lead screw and preventing excessive movement of the clamping plate from damaging the plastic workpiece and affecting the production quality of the laser engraving machine.

[0003] However, existing technologies have the following problems: In the positioning component structure of a CNC engraving machine, the clamping plate is hinged to the surface of the movable plate via a connecting rod, forming a basic workpiece fixing mechanism. However, since the current clamping plate adopts a fixed model design, its key parameters such as positioning size and clamping angle cannot be adjusted, resulting in significant limitations in actual operation. When it is necessary to position workpieces of different specifications and shapes, a corresponding dedicated positioning clamping plate must be matched. However, the existing non-replaceable fixed clamping plate structure can only adapt to the positioning needs of a single type of workpiece. This design defect directly limits the versatility and adaptability of the positioning component, which not only increases the operational complexity and time cost when changing different workpieces, but may also lead to a decrease in positioning accuracy due to mismatch between the clamping plate and the workpiece. Ultimately, this significantly reduces the efficiency of the CNC engraving machine's positioning component and the overall processing flexibility. Utility Model Content

[0004] The purpose of this invention is to provide an easily adjustable positioning component for engraving machines. This solves the problem that when positioning workpieces of different specifications and shapes, it is necessary to match corresponding special positioning clamps. However, the existing non-replaceable fixed clamp structure can only adapt to the positioning needs of a single type of workpiece. This design defect directly limits the versatility and adaptability of the positioning component. It not only increases the operational complexity and time cost when changing different workpieces, but may also lead to a decrease in positioning accuracy due to mismatch between the clamp and the workpiece. Ultimately, this significantly reduces the efficiency of the engraving machine positioning component and the overall processing flexibility.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 An easily adjustable engraving machine positioning component includes an engraving machine worktable 1. A motor 2 is fixedly connected to the left side of the rear side of the engraving machine worktable 1. A forward and reverse lead screw 3 is fixedly connected to the output end of the motor 2. Moving blocks 4 are threadedly connected to both sides of the surface of the forward and reverse lead screw 3. A moving frame 5 is fixedly connected to the rear side of the moving block 4. A clamping plate 6 is provided on the inner side of the moving frame 5. Mounting columns 7 are fixedly connected to the front and rear sides of the outer side of the clamping plate 6. The outer side of the mounting column 7 extends through to the outer side of the moving frame 5. A replacement and adjustment mechanism is fixedly connected to the outer side of the moving frame 5.

[0018] Please see Figure 1-6 The replacement adjustment mechanism includes a slot 81, which is located on the top of the mounting column 7. A card plate 82 is provided inside the slot 81. A spring piece 83 is fixedly connected to the top of the card plate 82. A mounting block 84 is fixedly connected to the top of the spring piece 83. The surface of the mounting block 84 is fixedly connected to the surface of the movable frame 5.

[0019] Furthermore, by changing the setting of the adjustment mechanism, the clamp 6 and the movable frame 5 can be quickly disassembled and fixed. The clamp 6 can be replaced without complicated tools, which simplifies the operation process, shortens the replacement time, ensures that the clamp 6 is firmly connected during use, and improves the practicality and reliability of the positioning component.

[0020] Please see Figure 1-5 The surface of the mounting block 84 is slidably connected to a stabilizing plate 9, and the bottom of the stabilizing plate 9 is fixedly connected to the surface of the card plate 82.

[0021] Furthermore, by setting the stabilizing plate frame 9, the movement direction of the clamping plate 82 can be guided and limited, preventing the clamping plate 82 from shifting or shaking during insertion and removal, ensuring precise docking between the clamping plate 82 and the slot 81, enhancing the structural stability of the replacement and adjustment mechanism, and further improving the smoothness of the clamping plate 6 disassembly and assembly and the firmness of the connection.

[0022] Please see Figure 1-5 A linkage plate 10 is fixedly connected to the bottom of the card plate 82, and the linkage plate 10 is located on the top of the engraving machine worktable 1.

[0023] Furthermore, by setting the linkage plate 10, the clamping plate 82 can be moved up and down by moving the linkage plate 10, so as to separate or clamp the clamping plate 82 from the clamping slot 81. There is no need to directly contact the small clamping plate 82 component, which optimizes the operation experience and makes the replacement of the clamping plate 6 more labor-saving and convenient.

[0024] Please see Figure 1 - Mounting rods 11 are provided at the four corners of the outer side of the clamping plate 6, and the outer side of the mounting rods 11 extends through to the outer side of the movable frame 5.

[0025] Furthermore, the mounting rod 11 provides multi-directional support and positioning for the clamping plate 6, preventing it from tilting or swaying during workpiece clamping or movement. This enhances the overall rigidity of the connection between the clamping plate 6 and the moving frame 5, ensuring that the clamping plate 6 maintains a stable posture during operation and improving the accuracy of workpiece positioning.

[0026] Please see Figure 1-5 A reinforcing sleeve 12 is fitted onto the surface of the mounting rod 11, and the surface of the reinforcing sleeve 12 is fixedly connected to the surface of the movable frame 5.

[0027] Furthermore, the reinforcement sleeve 12 further enhances the tightness and stability of the connection between the mounting rod 11 and the moving frame 5, reduces the deformation or shaking of the mounting rod 11 under stress, reduces the wear between the mounting rod 11 and the moving frame 5 after long-term use, extends the service life of the positioning components, and ensures the long-term stability of the positioning accuracy.

[0028] Please see Figure 1-3The top and bottom of the moving block 4 are slidably connected to the limit rod 13, and the surface of the limit rod 13 is fixedly connected to the surface of the engraving machine worktable 1.

[0029] Furthermore, by setting the limit rod 13, the movement trajectory of the moving block 4 can be strictly guided and limited, preventing the moving block 4 from rotating or deviating under the drive of the lead screw, ensuring that the moving block 4 drives the moving frame 5 and the clamping plate 6 to move smoothly along a straight line, ensuring the accuracy of the clamping plate 6 spacing adjustment, and improving the accuracy and stability of workpiece positioning.

[0030] The specific implementation process of this utility model is as follows: When in use, start the motor 2, the motor 2 drives the forward and reverse lead screw 3 to rotate, the forward and reverse lead screw 3 drives the moving block 4 and the moving frame 5 to move, the moving frame 5 drives the clamping plate 6 to move inward, and the clamping plate 6 can fix the workpiece on the top of the engraving machine worktable 1. When the engraving machine needs to engrave workpieces of other shapes. Push the connecting plate 10 upward, and the connecting plate 10 will drive the clamping plate 82 to move upward. The clamping plate 82 will exit the interior of the clamping slot 81, and the clamping slot 81 and the mounting column 7 will lose their fixation. Move the clamping plate 6 inward, and the clamping plate 6 will drive the mounting column 7 to move inward. The mounting column 7 will separate from the interior of the moving frame 5. Then, select another suitable clamping plate 6 of another model and install it on the surface of the moving frame 5. The positioning mechanism can be adjusted and replaced as needed.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
