Description

Technical Field

[0001] The utility model relates to the technical field of machining fixtures, and particularly relates to a novel machine tool jaw fixture. Background Art

[0002] A machine tool jaw fixture is a special fixture used on a machine tool. It realizes the firm clamping of a workpiece through structural components such as fixed jaws, sliding blocks, and rotating caps. The use of this fixture is to ensure that the workpiece maintains an accurate position and stability during the machining process, preventing machining errors caused by vibration or displacement. In scenarios such as machining, mold manufacturing, and part production, machine tool jaw fixtures are widely used. They can improve machining efficiency and ensure product quality, especially in an environment of high-precision and large-batch production, their role is particularly significant.

[0003] Traditional machine tool jaw fixtures usually achieve their effects through a relatively simple mechanical structure, mainly including parts such as fixed jaws, jaw bodies, clamping bolts, and bases. The fixed jaws are used to directly contact and clamp the workpiece, the jaw body serves as the support structure for the fixed jaws, the clamping bolts are rotated to tighten or loosen to achieve the clamping or release of the workpiece, and the base is used to fix the entire jaw fixture on the workbench of the machine tool. These structural components work together to ensure that the workpiece maintains the correct position during the machining process, thereby completing precise machining tasks.

[0004] However, for traditional machine tool jaw fixtures, their contact with the workpiece during clamping is generally point contact, which may cause the defect of being unable to firmly clamp the workpiece. Especially when clamping rough parts and when the depth of cut of the part to be machined is large, it is more likely to cause insufficient clamping force. Once this situation occurs, it is easy to reduce the surface quality of the workpiece. At the same time, it is also easy to cause damage to the cutting tool and even damage to the equipment. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a novel machine tool jaw fixture, aiming to improve the problem that the fixed jaw cannot be replaced due to wear during long-term use, resulting in the inability to clamp objects.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: a new type of machine tool jaw fixture, including a sleeve 1, a fixing piece 2 is fixedly connected inside the sleeve 1, a sliding rod 3 is slidably connected to the inner wall of the fixing piece 2, a first spring 4 is sleeved on the outer wall of the sliding rod 3, one end of the first spring 4 is fixedly connected to a tapered head 5, and the other end of the first spring 4 is fixedly connected to the outer wall of the fixing piece 2. A sliding collar 6 is slidably connected to the outer wall of the sleeve 1, a second spring 7 is sleeved on the outer wall of the sleeve 1, one end of the second spring 7 is fixedly connected to the outer wall of the sliding collar 6, a ball 8 is slidably connected to the inner wall of the sleeve 1, a fixed cylinder 9 is slidably connected to the inner wall of the sleeve 1, an arc plate 10 is fixedly connected to the outer wall of the fixed cylinder 9, a fixed jaw 13 is slidably connected to the outer wall of the arc plate 10, and a fixing component is arranged on the outer wall of the arc plate 10 for fixing the fixed jaw 13. The fixing component includes a fixing column 11, one end of the fixing column 11 is fixedly connected to the outer wall of the arc plate 10, and a jaw body 12 is slidably connected to the outer wall of the fixing column 11;

[0026] Specifically, when it is necessary to install or disassemble the fixed jaw 13, first, the opening of the sleeve 1 is sleeved on the fixed cylinder 9, and then the sliding collar 6 is slid so that the protrusion on the sliding collar 6 no longer blocks the ball 8. When the ball 8 is squeezed into the ball 8 inside the sleeve 1, the ball 8 will slightly shrink into the sleeve 1. When the groove of the fixed cylinder 9 passes by the ball 8, the ball 8 will be stuck in the groove on the fixed cylinder 9, and the first spring 4 between the tapered head 5 and the fixing piece 2 will also be forced to contract. Then, the sliding collar 6 is released, and the second spring 7 rebounds to block the protrusion of the sliding collar 6 against the ball 8. Then, the sliding collar 6 is slid again so that the ball 8 can be separated from the fixed cylinder 9, and the first spring 4 ejects the fixed cylinder 9 again, achieving the effect of quickly replacing the fixed jaw 13.

[0027] Referring to Figure 1 , Figure 4 and Figure 5, a supporting block 14 is fixedly connected to the outer wall of the fixed claw 13, a connecting block 24 is fixedly connected to the outer wall of the fixed claw 13, a bottom plate 15 is fixedly connected to the upper surface of the supporting block 14, a sliding ring 16 is fixedly connected to the upper surface of the bottom plate 15, a sliding bar 17 is slidably connected to the inner wall of the sliding ring 16, a connecting bar 18 is fixedly connected to the inner wall of the sliding bar 17, a right-angle bar 19 is rotatably connected to the outer wall of the connecting bar 18, one end of the sliding bar 17 is fixedly connected to the outer wall of the connecting block 24, the outer wall of the right-angle bar 19 is rotatably connected to the inner wall of the sliding bar 17, a rotating bar 20 is rotatably connected to the inner wall of the right-angle bar 19, a bolt 21 is rotatably connected to the inner wall of the right-angle bar 19, the outer wall of the bolt 21 is rotatably connected to the inner wall of the rotating bar 20, a nut 22 is threadedly connected to the outer wall of the bolt 21, a sliding groove block 23 is slidably connected to the outer wall of the bolt 21, and the lower surface of the nut 22 is fixedly connected to the upper surface of the bottom plate 15;

[0028] Specifically, when it is necessary to adjust the sliding fixed claw 13, first press down the right-angle bar 19, so that the right-angle bar 19 and the rotating bar 20 that rotate through the bolt 21 can rotate synchronously. The rotating right-angle bar 19 and rotating bar 20 will drive the bolt 21 to slide downward at the groove of the sliding groove block 23. At this time, the right-angle bar 19 and the rotating bar 20 will drive the sliding bar 17 to rotate through the connecting bar 18. However, due to the limitation of the sliding ring 16, the sliding bar 17 can only slide inside the sliding ring 16, so as to push the fixed claw 13 to slide along the arc surface of the arc-shaped plate 10 to both sides through the connecting block 24. When the right-angle bar 19 is pulled upward, the bolt 21 is driven to move upward, so that the sliding bar 17 pulls the fixed claw 13 to move closer to the middle through the connecting block 24. Then rotating the nut 22 can fix the position of the bolt 21, achieving the effect of being able to adjust the clamping size of the fixed claw 13.

[0029] Working principle: When it is necessary to replace the fixed claw 13, first put the opening part of the sleeve 1 on the fixed cylinder 9, then move the sliding collar 6 so that the protrusion on it no longer obstructs the movement of the ball 8. At this time, the ball 8 will slightly retract into the sleeve 1 under the pressure of the fixed cylinder 9 in the sleeve 1. When the notch of the fixed cylinder 9 slides past the ball 8, the ball 8 will be embedded in the notch of the fixed cylinder 9. At the same time, the spring one 4 between the cone head 5 and the fixed piece 2 will also contract due to the force. After releasing the sliding collar 6, the spring two 7 returns to its original state, and the sliding collar 6 clamps the ball 8 between the sleeve 1 and the fixed cylinder 9. Move the sliding collar 6 again so that the ball 8 can be separated from the fixed cylinder 9, and then the spring one 4 pushes out the fixed cylinder 9, achieving the effect of being able to quickly disassemble or install the fixed claw 13.

[0030] When it is necessary to adjust the distance between the two fixed claws 13, first press the right-angle bar 19. At this time, the right-angle bar 19 and the rotating bar 20 on the bolt 21 can rotate synchronously on the bolt 21, so that the right-angle bar 19 and the rotating bar 20 drive the bolt 21 to move downward along the notch of the sliding groove block 23. During this process, the right-angle bar 19 and the rotating bar 20 simultaneously push the sliding bar 17 to rotate through the connecting bar 18. Due to the limitation of the sliding ring 16, the sliding bar 17 can only slide inside the sliding ring 16. In this way, the fixed claw 13 is pushed to move along the arc surface side of the arc-shaped plate 10 through the connecting block 24. When the right-angle bar 19 is lifted upward, the bolt 21 moves upward accordingly, and the sliding bar 17 pulls the fixed claw 13 to gather towards the central position through the connecting block 24. Finally, the position of the bolt 21 can be locked by rotating the nut 22, achieving the effect of adjusting the clamping range of the fixed claw 13 by adjusting the distance between the fixed claws 13.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
