Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a quick-release fixture for machining machine tools. Background Technology

[0002] A machine tool fixture is a device used to fix a workpiece. It plays a vital role in the machining process. The main function of the fixture is to ensure that the workpiece is kept in the correct position and orientation on the machine tool so as to carry out precise cutting, drilling, milling and other machining operations. By firmly fixing the workpiece, the fixture can prevent the workpiece from moving or vibrating during the machining process, thereby ensuring machining accuracy and surface quality.

[0003] Existing machine tool fixtures typically rely on rotating a lead screw to drive the clamping plate to complete the clamping operation when clamping workpieces. However, traditional lead screw clamping methods often require manually rotating the lead screw to clamp or release the workpiece. This method is particularly time-consuming in production environments where workpieces are frequently changed, significantly reducing overall production efficiency.

[0004] To address the existing problems, there is a need to provide a quick-release fixture for machining tools. Utility Model Content

[0005] To overcome the drawback of the time-consuming rotation of the lead screw, this utility model provides a quick-release clamp for machining tools.

[0006] The technical solution of this utility model is as follows: A quick-release clamp for processing machine tools includes a base, a connecting frame, guide rods, a double-acting lead screw, a clamping plate, a first gear, a first rotating shaft, a second gear, a second rotating shaft, a third gear, a slider, a scale bar, and a rack. The connecting frame is connected to the base. Guide rods distributed front and back are symmetrically connected to the inside of the connecting frame. A double-acting lead screw is rotatably connected to the inside of the connecting frame. A clamping plate is symmetrically threaded onto the double-acting lead screw. The clamping plate slides with the guide rod at the corresponding position. A first gear is connected to the double-acting lead screw. A first rotating shaft is rotatably connected to the inside of the connecting frame. A second gear is connected to the first rotating shaft and meshes with the first gear. A second rotating shaft is rotatably connected to the inside of the connecting frame. A third gear is connected to the second rotating shaft and meshes with the second gear. A slider is slidably connected to the connecting frame. Scale bars are symmetrically connected to the left and right of the connecting frame. A rack is connected to the bottom of the slider and meshes with the third gear.

[0007] Preferably, the assembly also includes a mounting frame, telescopic rods, sliding plates, pressing plates, extrusion blocks, a first spring, a connecting plate, sliding rods, limiting blocks, a second spring, and fixing screws. Mounting frames are symmetrically mounted on the left and right sides of the slider. Telescopic rods are symmetrically connected front and back inside each mounting frame. Sliding plates are connected between the telescopic ends of the two telescopic rods on the same side. Pressing plates and extrusion blocks are connected to both sliding plates. A first spring is connected between the bottom of each sliding plate and the bottom of the corresponding mounting frame. Connecting plates are symmetrically placed on the connecting frame. Sliding rods are slidably connected inside each connecting plate. Limit blocks are connected to the inner ends of both sliding rods. A second spring is connected between each limit block and the corresponding connecting plate. Multiple adjustment holes are evenly spaced on the connecting frame. Fixing screws are symmetrically threaded onto each of the two connecting plates, with the four fixing screws threaded into the corresponding adjustment holes.

[0008] Preferably, it also includes a first protective pad, which is connected to both pressing plates.

[0009] Preferably, a second protective pad is also included, and the slider is connected to the second protective pad.

[0010] As a preferred option, it also includes anti-slip pads, with anti-slip pads connected inside both clamping plates.

[0011] As a preferred option, it also includes mounting plates, with mounting plates symmetrically connected to the left and right sides of the base.

[0012] The beneficial effects of this utility model are as follows: 1. The automated clamping process achieved by the slider and multiple gear transmission mechanism allows the operator to easily push the slider to quickly complete the workpiece clamping. Similarly, after processing, the clamping state can be quickly released by simply pressing the pressing plate and pushing the slider back to the initial position, thereby achieving the effect of quick workpiece removal, greatly reducing the time required for workpiece replacement, significantly improving production efficiency, and simplifying the operation process.

[0013] 2. The connecting plate can be placed in the position of the adjustment hole and fixed with the fixing screws, so as to ensure that the slider can be quickly moved to the appropriate position when pushed by the operator. This not only simplifies the positioning process of the slider, but also improves the accuracy and efficiency of operation. It can quickly adapt to the clamping requirements of different workpieces and realize flexible and efficient processing preparation. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example: A quick-release clamp for machine tools, such as Figures 1-7As shown, the system includes a base 1, a connecting frame 2, guide rods 3, a double-acting lead screw 4, a clamping plate 5, a first gear 6, a first rotating shaft 7, a second gear 8, a second rotating shaft 9, a third gear 10, a slider 11, a scale bar 1101, a rack 12, a mounting frame 13, a telescopic rod 14, a sliding plate 15, a pressing plate 1501, a pressing block 16, a first spring 17, a connecting plate 18, a sliding rod 19, a limiting block 20, a second spring 21, a fixing screw 23, a first protective pad 24, a second protective pad 25, an anti-slip pad 26, and a mounting plate 27. The connecting frame 2 is connected to the base 1. Guide rods 3 are symmetrically connected to the connecting frame 2, and a double-acting lead screw 4 is rotatably connected inside the connecting frame 2. A clamping plate 5 is symmetrically threaded onto the lead screw 4. The clamping plate 5 slides with the guide rod 3 at the corresponding position, and the clamping plate 5 can clamp the workpiece. A first gear 6 is connected to the bidirectional lead screw 4. A first rotating shaft 7 is rotatably connected inside the connecting frame 2. A second gear 8 is connected to the first rotating shaft 7 and meshes with the first gear 6. A second rotating shaft 9 is rotatably connected inside the connecting frame 2. A third gear 10 is connected to the second rotating shaft 9 and meshes with the second gear 8. A slider 11 is slidably connected to the connecting frame 2. Scale bars 1101 are symmetrically connected to the connecting frame 2. A rack 12 is connected to the bottom of the slider 11 and meshes with the third gear 10, which allows the bidirectional lead screw 4 to... The rod 4 rotates, and mounting frames 13 are symmetrically installed on the left and right sides of the slider 11. Telescopic rods 14 are symmetrically connected to the inside of each mounting frame 13. Sliding plates 15 are connected between the telescopic ends of the two telescopic rods 14 on the same side. Pressing plates 1501 are connected to each of the two sliding plates 15, and pressing blocks 16 are connected to each of the two sliding plates 15. First springs 17 are connected between the bottom of each sliding plate 15 and the bottom of the corresponding mounting frame 13. Connecting plates 18 are symmetrically placed on the connecting frame 2. Sliding rods 19 are slidably connected inside each of the two connecting plates 18. Limiting blocks 20 are connected to the inner ends of each of the two sliding rods 19 to limit the pressing blocks 16. The two limiting blocks 20 are positioned relative to the corresponding positions. A second spring 21 is connected between each of the connecting plates 18. Multiple adjustment holes 22 are evenly spaced on the connecting frame 2 to adjust the position of the connecting plates 18. Fixing screws 23 are symmetrically threaded on both connecting plates 18 to fix the connecting plates 18. The four fixing screws 23 are threaded into the corresponding adjustment holes 22. A first protective pad 24 is connected to each of the two pressing plates 1501 to facilitate pressing the pressing plates 1501. A second protective pad 25 is connected to the slider 11 to facilitate pushing the slider 11. Anti-slip pads 26 are connected inside both clamping plates 5 to prevent the workpiece from slipping. Mounting plates 27 are symmetrically connected to the left and right sides of the base 1 to facilitate the installation of the base 1.

[0024] When clamping the workpiece is required, the operator first places the two connecting plates 18 in the appropriate adjustment holes 22, and then installs the two connecting plates 18 with four fixing screws 23. After the installation of the two connecting plates 18 is completed, the operator can place the workpiece on top of the connecting frame 2, between the two clamping plates 5. After placing the workpiece, the operator pushes the slider 11 backward. The slider 11 drives all the connected parts to move. When the rack 12 moves, it drives the third gear 10 and the second rotating shaft 9 that mesh with it to rotate. The third gear 10 then drives the second gear 8 and the first rotating shaft 7 to rotate. The second gear 8 drives the first gear 6 to rotate. The first gear 6 drives the double-acting screw 4 to rotate. When the double-acting screw 4 rotates, it causes the two clamping plates 5 to move inward along the guide rod 3. When the pressing block 16 moves to a certain position, it will apply pressure to the limiting block 20, causing it to drive the sliding rod 19 to move backward and compress the second spring 21. When the two clamping plates 5 move to contact the workpiece and clamp it, the pressing block 16... When the slider 11 moves to the groove position of the limiting block 20, the pressure on the limiting block 20 is no longer applied. The second spring 21 drives the sliding rod 19 and the limiting block 20 to reset, so that the pressing block 16 engages with the groove on the limiting block 20, thereby limiting the slider 11. After that, the operator does not need to continue pushing the slider 11, thus completing the fixation of the workpiece. Subsequently, the operator can start processing the workpiece. When the workpiece is processed, if it is necessary to quickly disassemble the workpiece, the operator first presses down the two pressing plates 1501. This will drive the sliding plate 15 and the pressing block 16 to move. At the same time, the telescopic end of the telescopic rod 14 retracts, compressing the first spring 17. As the pressing block 16 moves, it will disengage from the locking state with the limiting block 20. Then, the operator pushes the slider 11 forward to the initial position. During this process, the movement of the rack 12 will cause the third gear 10 to rotate in the opposite direction, causing the bidirectional lead screw 4 to reverse, thereby driving the two clamping plates 5 to move outward, releasing the fixation of the workpiece. When the operator slides the slider 11 to the original position, the workpiece can be directly removed.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
