Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a CNC machine tool fixture that is easy to disassemble. Background Technology
[0002] CNC machine tools control the movement and operation of the machine tool through digital information. Its working principle can be summarized as follows: a machining program is written according to the part drawing using a selected "standard code". The machining program is then input into the CNC device, which controls the speed change, start and stop of the main motion of the machine tool, the direction, speed and displacement of the feed motion, as well as other actions such as tool selection and exchange, workpiece clamping and loosening, and cooling and lubrication start and stop. This ensures that the tool, workpiece and other auxiliary devices work strictly according to the sequence, path and parameters specified by the CNC program, thereby machining parts with the required shape, size and accuracy.
[0003] Traditional CNC machine tool fixture designs often connect the fixture to the machine tool spindle through complex fastening structures, such as using multiple bolts or nuts for fixing. While this design ensures the stability and reliability of the fixture during operation, it also brings great inconvenience when changing the fixture. When changing the fixture, operators not only need to spend a lot of time and effort to loosen these fasteners one by one, but also, performing such delicate operations in the narrow internal space of the machine tool is very easy to cause operational errors, which may damage the fixture or other parts of the machine tool. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing tooling design often lacks special tools or auxiliary systems for fixture replacement, which makes the entire replacement process more cumbersome and inefficient. To address this, we propose a CNC machine tool tooling that is easy to disassemble.
[0005] To achieve the above objectives, this application adopts the following technical solution: a CNC machine tool fixture that is easy to disassemble, comprising a CNC machine tool body, mounting plates fixedly connected to both sides of the top of the CNC machine tool body, a hydraulic rod fixedly connected to one side of the mounting plate, a mounting column fixedly connected to the side of the hydraulic rod away from the mounting plate, an adjusting column rotatably connected inside the mounting column, a clamp provided inside the adjusting column, adjusting grooves opened at both ends of the adjusting column, a push block slidably connected inside the adjusting groove, an insert rod fixedly connected to the side of the push block near the clamp, arc-shaped blocks fixedly connected to both ends inside the mounting column, a through hole opened inside the adjusting groove near the adjusting column, and an insert hole opened inside the clamp.
[0006] Preferably, both ends of the adjustment groove are provided with sliding grooves, and both ends of the push block are fixedly connected with sliders, the surface of the sliders being slidably connected to the inside of the sliding grooves.
[0007] Preferably, a storage spring is fixedly connected to the side of the push block near the insertion rod, and the side of the storage spring away from the insertion rod is fixedly connected to the inside of the adjustment groove.
[0008] Preferably, the size of the insertion rod is adapted to the size of the insertion hole, and the surface of the insertion rod is inserted into the interior of the insertion hole.
[0009] Preferably, a rubber pad is installed inside the mounting column on the side closest to the rubber pad.
[0010] Preferably, two annular blocks are fixedly connected to the surface of the adjusting column, and an annular groove is formed inside the mounting column.
[0011] Preferably, both ends of the adjusting column are provided with threaded grooves, and both ends of the mounting column are provided with threaded blocks.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, the operator rotates the adjusting column, causing the adjusting column to drive the push block to contact the thicker end of the arc-shaped block. This causes the push block to push the insertion rod into the insertion hole to fix the position of the clamp. This design allows the operator to disassemble the clamp, thereby enabling the replacement of the workpiece with a suitable clamp and facilitating the operator's disassembly and maintenance.

Detailed Implementation
[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a CNC machine tool fixture that is easy to disassemble, including a CNC machine tool body 1. Mounting plates 2 are fixedly connected to both sides of the top of the CNC machine tool body 1. A hydraulic rod 3 is fixedly connected to one side of the mounting plate 2. A mounting column 4 is fixedly connected to the side of the hydraulic rod 3 away from the mounting plate 2. An adjusting column 5 is rotatably connected inside the mounting column 4. A clamp 6 is provided inside the adjusting column 5. Adjusting grooves 7 are provided at both ends of the adjusting column 5. A push block 8 is slidably connected inside the adjusting groove 7. A insertion rod is fixedly connected to the side of the push block 8 near the clamp 6. 9. Both ends of the mounting column 4 are fixedly connected to arc-shaped blocks 10. The adjusting groove 7 has a through hole 11 on the side near the adjusting column 5. The clamp 6 has an insertion hole 12. By rotating the adjusting column 5, the operator causes the adjusting column 5 to drive the push block 8 to contact the thicker end of the arc-shaped block 10, thereby causing the push block 8 to push the insertion rod 9 into the insertion hole 12 to fix the position of the clamp 6. Through the above settings, the operator can disassemble the clamp 6 to replace the workpiece with a suitable clamp 6, and at the same time facilitate the operator's disassembly and maintenance.
[0022] Reference Figure 3 As shown in this embodiment: both ends of the adjusting groove 7 are provided with sliding grooves 13, and both ends of the push block 8 are fixedly connected with sliders 14. The surface of the sliders 14 is slidably connected to the inside of the sliding grooves 13. When the operator moves the push block 8, the push block 8 drives the sliders 14 to slide inside the sliding grooves 13. Through the above settings, the frictional resistance of the push block 8 during the movement can be effectively reduced, improving the smoothness of operation and the durability of the equipment. At the same time, the sliding connection design between the sliders 14 and the sliding grooves 13 ensures the stability and accuracy of the push block 8 during the movement, avoiding energy loss and component wear caused by excessive friction.
[0023] Reference Figure 3 As shown in this embodiment: a storage spring 15 is fixedly connected to the side of the push block 8 near the insertion rod 9, and the side of the storage spring 15 away from the insertion rod 9 is fixedly connected to the inside of the adjustment groove 7. When the adjustment column 5 drives the push block 8 and the arc block 10 to be relatively thick, the push block 8 squeezes the storage spring 15 to compress and store force, and drives the insertion rod 9 to be inserted into the insertion hole 12 for fixation. When the operator releases the contact between the push block 8 and the arc block 10, the push block 8 is quickly pushed to the outside of the adjustment groove 7 under the action of the rebound force of the storage spring 15, and the insertion rod 9 is released from the limit between itself and the insertion hole 12.
[0024] Reference Figure 3 As shown in this embodiment, the size of the plug rod 9 is adapted to the size of the socket 12, and the surface of the plug rod 9 is inserted into the interior of the socket 12. By adapting the size of the plug rod 9 to the size of the socket 12, the plug rod 9 can be firmly inserted into the socket 12 to form a tight connection. This insertion design ensures the firmness between components. At the same time, the precise size matching effectively avoids equipment failure caused by loosening or misalignment, further improving the stability and service life of the overall structure.
[0025] Reference Figure 3 As shown in this embodiment: a rubber pad 16 is installed inside the mounting column 4 on the side near the rubber pad 16. By installing the rubber pad 16 inside the mounting column 4 on the side near the clamp 6, the clamp 6 can provide a more uniform and stable pressure distribution when clamping the workpiece, effectively preventing deformation or damage to the workpiece due to uneven force during processing. The softness of the rubber pad 16 not only increases the friction between the clamp 6 and the workpiece contact surface, but also absorbs and buffers the vibration generated during processing to a certain extent, further improving processing accuracy and surface quality.
[0026] Reference Figure 3 As shown in this embodiment: two annular blocks 18 are fixedly connected to the surface of the adjusting column 5, and two annular grooves 17 are opened inside the mounting column 4. When the operator rotates the adjusting column 5, the adjusting column 5 drives the annular blocks 18 to rotate inside the annular grooves 17. Through the above settings, smooth transmission between the adjusting column 5 and the mounting column 4 can be achieved, effectively reducing friction and wear, and improving the stability and durability of the equipment operation.
[0027] Reference Figure 4 and Figure 5 As shown in this embodiment: threaded grooves 19 are provided at both ends of the adjusting column 5, and threaded blocks 20 are provided at both ends of the mounting column 4. By setting the threaded grooves 19 and threaded blocks 20, the operator inserts the threaded blocks 20 into the threaded grooves 19 to fix the position of the adjusting column 5 inside the mounting column 4, so as to prevent the adjusting column 5 from shaking and causing the limit between the arc block 10 and the push block 8 to be unstable.
[0028] Working principle: By rotating the adjusting column 5, the operator causes the push block 8 to contact the thicker end of the arc-shaped block 10. This push block 8 then pushes the insertion rod 9 into the insertion hole 12, fixing the position of the clamp 6. This design allows the operator to disassemble the clamp 6, enabling the replacement of the workpiece with a suitable clamp 6. It also facilitates disassembly and maintenance. When the operator moves the push block 8, it causes the slider 14 to slide within the slide groove 13. This design effectively reduces the frictional resistance of the push block 8 during movement, improving the smoothness of operation and the durability of the equipment. The sliding connection design between slider 14 and groove 13 ensures the stability and accuracy of push block 8 during movement, avoiding energy loss and component wear caused by excessive friction. When the adjusting column 5 drives push block 8 to make contact with arc block 10, push block 8 compresses the storage spring 15 to store force, and drives the insertion rod 9 to insert into the insertion hole 12 for fixation. When the operator releases the contact between push block 8 and arc block 10, the rebound force of storage spring 15 quickly pushes push block 8 to move out of adjusting groove 7, and releases the limit between insertion rod 9 and insertion hole 12. The size of insertion rod 9 is adapted to the size of insertion hole 12. The design allows the insertion rod 9 to be securely inserted into the insertion hole 12, forming a tight connection. This insertion design ensures the robustness between components. Simultaneously, precise dimensional matching effectively prevents equipment malfunctions caused by loosening or misalignment, further enhancing the overall structural stability and service life. The installation of a rubber pad 16 inside the mounting column 4 near the clamp 6 provides a more uniform and stable pressure distribution when clamping the workpiece, effectively preventing deformation or damage to the workpiece during processing due to uneven force. The softness of the rubber pad 16 not only increases the friction between the clamp 6 and the workpiece contact surface but also... To a certain extent, it absorbs and buffers the vibration generated during the processing, further improving the processing accuracy and surface quality. When the operator rotates the adjusting column 5, the adjusting column 5 drives the annular groove 17 to rotate inside the annular block 18. Through the above settings, smooth transmission between the adjusting column 5 and the mounting column 4 can be achieved, effectively reducing friction and wear, and improving the stability and durability of the equipment operation. Through the setting of the threaded groove 19 and the threaded block 20, the operator inserts the threaded block 20 into the threaded groove 19 to fix the position of the adjusting column 5 inside the mounting column 4, preventing the adjusting column 5 from shaking and causing the limit between the arc block 10 and the push block 8 to become unstable.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
