Description

Technical Field

[0001] This invention relates to the technical field of mechanical manufacturing and processing, and in particular to a multi-configuration high-efficiency vibration-resistant vise. Background Technology

[0002] In machining, for some workpieces with low hardness, high surface roughness requirements, or special contour shapes that cannot be clamped with a flat surface, such as precision parts, non-ferrous metal parts, and curved surface parts, soft jaw vises can not only directly clamp the workpieces, but also pre-machine the required shapes on them to clamp irregularly shaped parts, ultimately ensuring the accuracy and surface quality of the workpieces.

[0003] Patent document CN218776419U discloses a movable vise structure of a modular vise-type clamp. This structure uses threaded holes in the soft jaws to fix the soft jaws onto the jaws with bolts. The fit between the bolts and the threaded holes requires a certain assembly clearance. Moreover, the soft jaws are usually made of flexible materials such as aluminum, polyurethane, and nylon, which are prone to deformation under stress or temperature changes. This results in a significant deviation in the relative position of the soft jaws to the jaws after one disassembly and assembly, affecting the repeatability of positioning accuracy and making it difficult to meet the requirements of high-precision machining. Furthermore, the soft jaws need to be replaced by tightening or loosening multiple bolts one by one during disassembly and assembly. Especially in small-batch, multi-category changeover scenarios, repeated operations significantly increase auxiliary time and reduce the overall efficiency of workpiece processing.

[0004] Patent document CN221676926U discloses a pneumatic vise with a self-locking mechanism. This vise uses a multiplier cylinder for pressurization, which is installed at the rear of the vise body, increasing the overall length of the vise. Locking is achieved by directly pushing the piston rod of the multiplier cylinder, and its clamping force relies entirely on the cylinder output. To obtain a greater clamping force, it is necessary to increase the cylinder diameter and lengthen the cylinder body, resulting in an increase in the overall size of the vise, occupying internal space of the machine tool, increasing the risk of interference with the machine tool during processing, and reducing the usability of the fixture. Because the working direction of the cylinder is aligned with the reaction force of the workpiece, and gas is compressible, changes in cutting force during processing cause the cylinder piston to vibrate back and forth, leading to unstable workpiece clamping and resulting in vibration marks on the workpiece surface. While the vise incorporates a self-locking mechanism on the side to achieve cylinder self-locking and achieve stable clamping, this significantly increases the size of the vise. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art and propose a multi-configuration high-efficiency anti-vibration vise that can quickly change the soft jaws according to the clamping requirements of parts with different shapes; the design of converting pneumatic driving force into mechanical locking force can solve the above-mentioned processing vibration problem.

[0016] Preferably, the first conical head has symmetrical beveled surfaces on both sides, and the beveled surfaces match the beveled conical surfaces.

[0017] Preferably, the power cylinder is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0018] The beneficial effects of this invention are: 1. This invention installs positioning pull studs on both sides of the soft jaws and inserts the limiting clips of the positioning pull studs into the positioning grooves of the jaws. The positioning grooves radially fix the limiting clips, and the first conical head of the locking pins can axially fix the locking ring groove of the limiting clips. The locking pins on both sides are connected by a return spring. When no force is applied, they will move away from each other and disengage from the locking ring groove. The drive mechanism drives the main push rod to move back and forth, which can make the locking pins on both sides move away from each other or move closer to each other, thereby achieving the locking and unlocking of the soft jaws and achieving the purpose of quickly changing the soft jaws. This allows the vise to have multiple configuration functions and adapt to diverse operation needs. 2. In its natural state, the spring component presses against the moving piston, bringing the locking pin close to the positioning pull pin. When gas or liquid pressure is input through the second delivery channel, the spring component is flattened and deformed, causing the locking pin to loosen the soft jaws. When the pressure is closed, the spring component returns to its original shape, thus clamping the soft jaws. Therefore, even if the pressure source suddenly fails, the soft jaws will not loosen, ensuring the reliability of clamping. When the locking force provided by the spring component is insufficient, pressure can be input through the first input channel to increase the locking force on the soft jaws. 3. The combined structure of the power cylinder, the pressure-boosting locking block, and the lever transforms the output force of the power cylinder from a direct linear push mode to a force boosting effect achieved by the rotation of the lever. The lever's lever arm amplification effect increases the final clamping force, reduces the working stroke, shortens the overall length of the vise, significantly reduces the equipment size, and improves space utilization.

[0022] Example 1 See Figures 1 to 8A multi-configuration high-efficiency vibration-resistant vise includes a vise body 1 with two jaws 2. One jaw is a fixed jaw fixed to the vise body 1, and the other is a movable jaw threaded onto a lead screw 3. Flexible jaws 4 are installed on the jaws 2. Positioning grooves 21 are formed on both sides of the jaws 2, and positioning rivets 5 are installed within the positioning grooves 21. Each positioning rivet 5 includes a limiting head 51 and a connecting rod 52. The connecting rod 52 is connected to the flexible jaw 4. A locking ring groove 53 is formed on the outer side of the limiting head 51. The depth of the locking ring groove 53 gradually decreases from the center to both sides, forming symmetrical oblique conical surfaces 54 on both sides. A locking groove 22 is also formed on the jaws 2, which is perpendicularly connected to the positioning groove 21. Both oblique conical surfaces 54 are located within the locking groove. In section 22, locking pins 7 are slidably installed on both sides of the locking groove 22. The locking pin 7 has a first conical head 71 at one end near the positioning pull pin 5. The first conical head 71 matches and abuts against the locking ring groove 53. The middle of the locking groove 22 is vertically connected to an input groove 23. A main push rod 6 is slidably installed in the input groove 23. The main push rod 6 has a second conical head 61 at one end near the locking groove 22. Both locking pins 7 have a first driving inclined surface 72 at one end near the main push rod 6. The two first driving inclined surfaces 72 match and abut against both sides of the second conical head 61 respectively. The locking pins 7 on both sides are connected by a return spring 73. The main push rod 6 is connected to a driving mechanism. The driving mechanism drives the main push rod 6 to slide, so that the locking pins 7 on both sides move away from each other or move closer to each other. The drive mechanism in this embodiment is in automatic mode; The drive mechanism includes a mounting groove 27, and the input groove 23 is connected to the mounting groove 27. A movable piston 271 is provided in the mounting groove 27. A piston rod 272 is provided on the side of the movable piston 271 near the main push rod 6. The end of the piston rod 272 abuts against the main push rod 6. An abutment block 273 is provided on the side of the mounting groove 27 away from the limiting block. A spring is provided between the abutment block 273 and the movable piston 271. When the spring is in its natural state, the first conical head 71 of the locking pins 7 on both sides respectively engages in the locking ring groove 53 of the positioning pull pins 5 on both sides, thereby axially limiting the positioning pull pins 5. The mounting groove 27 is connected to the first conveying channel 274, and the input groove 23 is connected to the second conveying channel 275. The outer side of the moving piston 271 is provided with a first sealing ring, and the outer side of the main push rod 6 is provided with a second sealing ring. The second conveying channel 275 is connected to a conveying pipe, and the conveying pipe is provided with a locking control valve 11. Gas or liquid is conveyed into the mounting groove 27 through the first conveying channel 274 to apply pressure to the moving piston 271 in the forward direction, increasing the pressure of the locking pin 7 clamping the positioning pull pin 5. Gas or liquid is conveyed into the input groove 23 through the second conveying channel 275 to apply pressure to the moving piston 271 in the reverse direction. The spring is compressed, and the locking pin 7 is disengaged from the locking ring groove 53 under the reset action of the return spring 73. The opening and closing of the conveying pipe is realized by operating the locking control valve 11. The spring component is a disc spring; The outer diameter of the limiting clamp 51 is larger than the outer diameter of the connecting rod 52. The limiting clamp 51 and the connecting rod 52 are detachable and installable. The soft jaw 4 has a through hole 41. The limiting clamp 51 has a positioning sleeve 55. The through hole 41 has a matching positioning groove 42. The positioning sleeve 55 has a threaded groove 56. The connecting rod 52 is a screw. One end of the screw is threaded into the threaded groove 56, and the other end is threaded into the through hole 41. The clamp body 1 is provided with a mounting base 12, and the mounting base 12 has a mounting hole 13. The head of the lead screw 3 is provided with a mounting part 31, which is rotatably mounted in the mounting hole 13. Below the mounting hole 13 is a receiving groove 14, in which a first cylindrical pin 15 is provided. A force multiplier lever 8 is rotatably mounted on the first cylindrical pin 15. The force multiplier lever 8 is provided with a locking block 81. The end of the mounting part 31 away from the lead screw 3 is provided with a driving part 32, and the driving part 32 is provided with a locking sleeve 33. The bottom of the locking sleeve 33 is provided with a locking groove 34, which is matched and installed with the locking block 81. The end of the lever 8 away from the mounting base 12 is provided with a second cylindrical pin 82. The bottom of the clamp body 1 is equipped with a power cylinder 10. The output end of the power cylinder 10 is provided with a piston rod. The end of the piston rod is equipped with a pressure-boosting locking block 9. The pressure-boosting locking block 9 is provided with an inclined strip groove 91. A first cylindrical pin 15 is slidably installed in the strip groove 91. The first cylindrical pin 15 is connected to the lever 8. The outer diameter of the driving part 32 is smaller than the outer diameter of the mounting part 31. A limiting bushing 35 is sleeved on the driving part 32. The limiting bushing 35 is provided with an insertion hole. A limiting pin 36 is provided in the insertion hole. The limiting pin 36 is radially inserted through the driving part 32. The power cylinder 10 is a double-acting cylinder. The air inlet of the double-acting cylinder is connected to an air source through an air supply pipe. A control valve and a pressure regulating valve are installed on the air supply pipe. Both the control valve and the pressure regulating valve are installed on the clamp body 1. A pressure gauge is provided on the pressure regulating valve. By controlling the opening and closing of the control valve, the air supply to the cylinder can be switched on or off, and the locking force of the vise can be controlled by adjusting the pressure regulating valve.

[0023] The power cylinder 10 can also be equipped with a hydraulic cylinder or an electric cylinder, which can be stably controlled by the corresponding control components.

[0024] The first conical head 71 has symmetrical beveled surfaces on both sides, and the beveled surfaces match the beveled conical surface 54; The structure of the second conical head is the same as that of the first conical head; A spring groove for accommodating the return spring 73 is provided on the end face of the locking pin 7; The outer side of the second cylindrical pin 82 is fitted with a protective bushing.

[0025] In its natural state, the spring will always press the main push rod. As the main push rod advances, it separates the locking pins on both sides through the second conical head, so that the first conical head of the locking pin is engaged in the locking ring groove, which axially fixes the limit clamp head and ensures the reliability of the soft jaw installation.

[0026] When the locking force provided by the spring is insufficient and it is necessary to increase the locking force, the first conveying channel can input air pressure or hydraulic pressure to increase the pressure and increase the locking force.

[0027] When air or hydraulic pressure is supplied to the second conveying channel, the spring can be compressed, the main push rod can be retracted, and the locking pins on both sides can be brought closer to each other under the action of the return spring, so that the locking pins can release the locking pins from the positioning pull pins, thus achieving the purpose of automatic unlocking.

[0028] When the locking control valve is closed, the second conveying channel cannot deliver pressure, and the locking pin always locks the positioning pull pin. Only when the switch is opened can pressure be delivered to the second conveying channel, compressing the spring component, unlocking the locking pin from the positioning pull pin, allowing the soft jaws to be disassembled, effectively preventing accidental loosening and improving structural reliability.

[0029] Example 2 See Figures 9 to 13In this embodiment, the driving mechanism is in manual mode. The driving mechanism includes a driving groove 24. The jaw 2 has a driving groove 24. The driving groove 24 is perpendicularly connected to the input groove 23. A driving rod 25 is slidably installed in the driving groove 24. The end of the driving rod 25 is provided with a third conical head 251. The input groove 23 is provided with a balance pin 26 and a transition pin 62. The balance pin 26 and the transition pin 62 are respectively located on both sides of the driving rod 25. The transition pin 62 abuts against the main push rod 6. The end of the balance pin 26 and the transition pin 62 near the driving rod 25 is provided with a second driving inclined surface 261. The two second driving inclined surfaces 261 respectively match and abut against both sides of the third conical head 251. A driving bolt 241 is threadedly installed at the opening of the driving groove 24. The bottom of the driving bolt 241 abuts against the driving rod 25. The top of the driving bolt 241 is provided with a driving head 242. A blocking block is provided on the side of the balance pin 26 away from the drive rod 25, and a spring is provided between the blocking block and the balance pin. A spring is also provided between the transition pin 62 and the main push rod 6. Everything else is the same as in Example 1.

[0030] In this embodiment, the soft jaws are fixed and unlocked by manually rotating the drive bolt. During installation, the drive bolt is rotated from the side to screw it into the drive groove. The drive bolt pushes the drive rod between the balance pin and the transition pin, causing the transition pin to push the main push rod forward, which in turn moves the locking pins on both sides away from each other. The first conical head of the locking pin engages with the locking ring groove to achieve locking. During disassembly, the drive bolt is unscrewed, and the locking pins on both sides move closer together to release the lock.

[0031] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
