A second spring is fixedly connected to the left side of the outer wall of the locking block. A sliding rod is slidably connected to the upper and lower sides of the left end of the extrusion rod.

[0009] As a further description of the above technical solution:

[0010] An anti-slip pad is fixedly connected to the left side of the clamping head, and a shock-absorbing pad is fixedly connected to the right side of the outer wall of the clamping head.

[0011] As a further description of the above technical solution:

[0012] A brake motor is fixedly connected to the rear right end of the bottom of the operating platform. The output end of the brake motor passes through the top of the operating platform and is fixedly connected to a gear. The outer wall of the gear meshes with the outer wall of the rack.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when it is necessary to fix the workpiece, rotating the control ring causes the inner wall protrusion block to quickly press the extrusion rod towards the center, thus quickly and steadily clamping the workpiece. After processing, simply rotating the control ring in the opposite direction allows the extrusion rod to quickly return to its original position with the help of the spring's reset action, thereby achieving rapid removal of the workpiece. This greatly reduces the time loss of workpiece clamping and effectively improves the overall working efficiency of machine tool processing.

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.

[0033] Reference Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of a multi-functional machine tool machining center fixture, including an operating table 1. A fixing ring 4 is fixedly connected to the top of the operating table 1, and the fixing ring 4 is fixedly connected to the operating table 1. Multiple square holes 10 are formed on the inner wall of the fixing ring 4. A pressing rod 5 is slidably connected to the inner wall of each of the multiple square holes 10. The inner wall of the square holes 10 is consistent with the outer wall of the pressing rod 5. The pressing rod 5 can slide on the fixing ring 4 by relying on the square holes 10. A fixing plate 6 is fixedly connected to the opposite side of each of the multiple pressing rods 5. A guide tube 7 is fixedly connected to the outer wall of the fixing plate 6. The fixing plate 6 is connected to the rear side of the pressing rod 5, and is used to connect the guide tube 7 and the bottom of the pressing rod 5 together. A spring 9 is fixedly connected to the bottom of the inner wall of the guide tube 7. A guide rod 8 is fixedly connected to the top of the spring 9. The spring 9 is connected to the inner wall of the guide tube 7, and one end of the spring 9 is connected to the guide rod 8. Rod 8 is fixedly connected. Guide rod 8 can slide on the inner wall of guide tube 7 and can be reset by spring 9. The adjacent sides of multiple guide rods 8 are fixedly connected to the outer wall of fixed ring 4. When the extrusion rod 5 moves, it can be reset by spring 9 which is indirectly connected to it. Control ring 3 is slidably connected to the opposite side of multiple fixed plates 6. The opposite end of fixed plate 6 is slidably connected to the inner wall of control ring 3. The inner wall of control ring 3 is provided with protrusion block. When control ring 3 rotates, its inner wall contacts multiple fixed plates 6 and extrudes the extrusion rod 5 towards the center, which can fix and clamp the workpiece to be clamped. A rack 11 is fixedly connected to the outer wall of control ring 3. The rack 11 is connected to the outer wall of control ring 3 and is used to control the rotation of control ring 3. A replacement mechanism 2 is provided on the adjacent side of multiple extrusion rods 5. The replacement mechanism 2 is used to quickly change the clamp head.

[0034] Reference Figure 1 , Figure 3 and Figure 5The replacement mechanism 2 includes a connecting cavity 201, which is located on the left side of the extrusion rod 5 and is used to connect to the rear side of the clamping head 202. The clamping head 202 is slidably connected to the inner wall of the connecting cavity 201. The upper and lower sides of the outer wall of the clamping head 202 are provided with slots 203, which match the locking blocks 204. When the clamping head 202 enters the connecting cavity 201, the locking blocks 204 can fix the clamping head 202. The upper and lower sides of the inner wall of the connecting cavity 201 are rotatably connected to the rotating shafts 206. The outer walls of the two rotating shafts 206 are rotatably connected to the locking blocks 204. The rotating shafts 206 are used to rotatably connect the locking blocks 204 to the inner wall of the connecting cavity 201. The rotating shafts 206 are connected to the middle of the locking blocks 204. The left side of the outer wall of the locking blocks 204 is fixedly connected to the spring 205. The two ends of the second spring 205 are connected to the left side of the clamping block 204 and the inner wall of the connecting cavity 201, respectively. When there is no external force, the left end of the clamping block 204 protrudes from the inner wall of the connecting cavity 201. When the rear side of the clamping head 202 enters the inner wall of the connecting cavity 201, the protruding part of the left end of the clamping block 204 is squeezed and retracted upwards until the clamping groove 203 slides to the position of the clamping block 204. The second spring 205 applies a pushing force to embed the left side of the clamping block 204 into the clamping groove 203 to achieve fixation. The upper and lower sides of the left end of the compression rod 5 are slidably connected to the sliding rod 207. The sliding rod 207 penetrates the outer wall of the compression rod 5 and contacts the right end of the clamping block 204. Pressing the sliding rod 207 applies pressure to the right end of the clamping block 204. At this time, the left end of the clamping block 204 can be retracted, ending the fixation of the clamping head 202.

[0035] Reference Figure 1 , Figure 3 and Figure 6 An anti-slip pad 12 is fixedly connected to the left side of the clamping head 202. The anti-slip pad 12 is used to prevent slippage when the clamping head 202 clamps the workpiece. A shock-absorbing pad 13 is fixedly connected to the right side of the outer wall of the clamping head 202. When clamping the workpiece, it can absorb the impact force, making the clamping head 202 more stable when it is engaged with the inner wall of the extrusion rod 5. A brake motor 14 is fixedly connected to the right rear end of the bottom of the operating table 1. The output end of the brake motor 14 passes through the top of the operating table 1 and is fixedly connected to a gear 24. The brake motor 14 is connected to... At the bottom of the operating platform 1, gear 24 is connected to brake motor 14. The outer wall of gear 24 meshes with the outer wall of rack 11. When brake motor 14 starts, transmission gear 24 rotates, thereby driving control ring 3 to rotate. A slot 15 is provided at the center of the top of the operating platform 1. A lifting plate 16 is slidably connected to the inner wall of slot 15. The outer wall of lifting plate 16 is consistent with the inner wall of slot 15. A telescopic rod 17 is fixedly connected to the bottom of lifting plate 16. The telescopic rod 17 can control the lifting plate 16 to move up and down.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The bottom of the telescopic rod 17 is fixedly connected to a fixed base plate 19. Support feet 18 are fixedly connected to the four corners of the bottom of the fixed base plate 19. The fixed base plate 19 is used to support the telescopic rod 17 to move the lifting plate 16. An indicator light 23 is fixedly connected to the top left of the operating table 1. The indicator light 23 can indicate the working status of the device when the workpiece is clamped. A protective shell 20 is fixedly connected to the top of the operating table 1. The protective shell 20 is used to protect the inside of the clamping device from dust contamination. A sliding groove 22 is opened at the bottom of the control ring 3. A slide rail 21 is slidably connected to the inner wall of the sliding groove 22. The bottom of the slide rail 21 is fixedly connected to the top of the operating table 1. The sliding groove 22 and the slide rail 21 fit together. The slide rail 21 is fixed to the top of the operating table 1 to enhance the stability of the control ring 3 when it rotates.

[0037] Working principle: The workpiece is placed on the operating table 1 and located in the area of ​​the middle of the fixed ring 4. When the workpiece needs to be clamped, the brake motor 14 works, controlling the gear 24 at its output end to rotate, thereby driving the control ring 3 to rotate. Since there are protruding blocks on the inner wall of the control ring 3, during its rotation, the protruding blocks contact multiple fixed plates 6 and squeeze the pressing rod 5 through the square hole 10 towards the middle of the fixed ring 4. The pressing rod 5 drives the clamping head on its adjacent side to move closer to the workpiece, thereby achieving the fixed clamping of the workpiece. During the movement of the pressing rod 5, the spring 9 indirectly connected to the pressing rod 5 is compressed, and the guide rod 8 slides in the guide tube 7. When the processing is completed and the workpiece needs to be released, the brake motor 14 rotates the control ring 3 in the opposite direction. At this time, the compressed spring 9 pushes the guide rod 8 by its own elastic force, thereby driving the pressing rod 5 to move away from the center of the fixed ring 4, so that the clamping head releases the workpiece, so that the workpiece can be taken out and replaced.

[0038] Furthermore, when the clamping head 202 needs to be installed, align the rear side of the clamping head 202 with the connecting cavity 201 on the extrusion rod 5 and insert it into the cavity. During insertion, the clamping head 202 will compress the locking blocks 204 that are rotatably connected to the upper and lower sides of the inner wall of the connecting cavity 201 via the rotating shaft 206. Since the outer left side of the locking block 204 is connected to the second spring 205, under the compression of the clamping head 202, the second spring 205 is compressed, and the locking block 204 rotates around the rotating shaft 206 and retracts, allowing the clamping head 202 to continue to slide smoothly into the connecting cavity 201. When the clamping head 202 is fully inserted and the slot 203 on its outer wall slides to the position of the corresponding locking block 204, the spring... The second spring 205 releases its elastic force, applying a pushing force to the locking block 204, causing the left side of the locking block 204 to embed into the slot 203, thus fixing the clamping head 202 within the connecting cavity 201. When the clamping head 202 needs to be removed, press the sliding rod 207, which is slidably connected to the upper and lower sides of the left end of the extrusion rod 5. The sliding rod 207 will penetrate the outer wall of the extrusion rod 5 and apply pressure to the right end of the locking block 204. The locking block 204 overcomes the elastic force of the second spring 205 and rotates around the rotating shaft 206, causing the left end of the locking block 204 to disengage from the slot 203 and retract, releasing the fixation of the clamping head 202. The clamping head 202 can then be pulled out of the connecting cavity 201, completing the disassembly of the clamping head 202.

[0039] 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. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
