[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0019] This utility model provides, for example Figure 1-4 The fixture shown includes a fixing mechanism 1 and a quick-adjustment mechanism 2. The fixing mechanism 1 consists of a base plate 11, a U-shaped plate 12, two limiting slide grooves, two limiting sliders 13, a clamping plate 14, and a threaded rod 15. The U-shaped plate 12 is fixedly connected to the top of the base plate 11. The two limiting slide grooves are symmetrically opened on both sides of the inner wall of the U-shaped plate 12. The two limiting sliders 13 are slidably sleeved in the inner cavity of the corresponding limiting slide groove. The limiting sliders 13 and the limiting slide grooves are used to ensure that the clamping plate 14 can move smoothly in the vertical direction. The clamping plate 14 is fixedly connected between the two limiting sliders 13. The clamping plate 14 and the base plate 11 cooperate to complete the clamping and fixing of the workpiece. The threaded rod 15 is rotatably connected to the top of the clamping plate 14. The quick-adjustment mechanism 2 is used to reduce the time of rotating the threaded rod 15, simplify the operation, and improve convenience. The quick-adjustment mechanism 2 includes a rectangular hole at the top of the U-shaped plate 12. A rectangular ring 21 is positioned above the rectangular hole and is fixedly connected to the top of the U-shaped plate 12. The inner diameter of the rectangular hole and the rectangular ring 21 are the same. A strip-shaped lifting block 22 is located within the inner cavity of the rectangular ring 21. Anti-detachment grooves are symmetrically provided on the front and back of the strip-shaped lifting block 22. Anti-detachment sliders 24 are symmetrically fixedly connected to the inner wall of the rectangular ring 21. The outer walls of the two anti-detachment sliders 24 slide and engage with the inner cavities of the corresponding anti-detachment grooves. The anti-detachment sliders 24 and the anti-detachment grooves are used to prevent the strip-shaped lifting block 22 from slipping. 2. Completely detached from the rectangular hole and rectangular ring 21, the top of the strip-shaped lifting block 22 is provided with a threaded hole, the inner wall of which is threadedly connected to the outer wall of the threaded rod 15. The top of the U-shaped plate 12 is provided with a locking assembly 23, which consists of a U-shaped block 231, a U-shaped cavity, a U-shaped driving block 232, a driving hole, a driving bolt 233, two cross-shaped holes, two cross-shaped force rods 234, two return springs 235, two circular through holes, multiple locking holes, and two locking rods 236. The U-shaped block 231 is fixedly connected to the top of the U-shaped plate 12, and the U-shaped cavity is opened in the U-shaped hole. Inside the U-shaped block 231, a U-shaped drive block 232 is located within the U-shaped cavity. Both ends of the U-shaped drive block 232 have inclined surfaces. The U-shaped drive block 232 drives the cross-shaped force-bearing rod 234 to move via these inclined surfaces. A drive hole is located on the front of the U-shaped block 231. The outer wall of the drive bolt 233 is threaded to the inner wall of the drive hole. Two cross-shaped holes are symmetrically located on the inner wall of the U-shaped block 231. Two cross-shaped force-bearing rods 234 are slidably fitted into the inner cavities of the corresponding cross-shaped holes. One end of the cross-shaped force-bearing rod 234 facing the U-shaped drive block 232 has a rounded corner. The return spring 235 is sleeved on the outer wall of the corresponding cross-shaped force rod 234. The return spring 235 is used to drive the cross-shaped force rod 234 and the locking rod 236 to automatically perform a return movement. Two circular through holes are symmetrically opened on the outer wall of the rectangular ring 21. Multiple locking holes are opened in a rectangular array on the outer wall of the strip-shaped lifting block 22. Two locking holes are opened on the two sides of the strip-shaped lifting block 22 respectively. Two locking rods 236 are fixedly connected to the outer wall of the corresponding cross-shaped force rod 234. The opposing ends of the two locking rods 236 are movably sleeved with the inner cavity of the corresponding locking hole. The top of the threaded rod 15 is provided with a rotating component 3, which includes a rotating block 31. The rotating block 31 is fixedly connected to the top of the threaded rod 15. The outer wall of the rotating block 31 is provided with a through hole, and the inner cavity of the through hole is provided with an auxiliary rotating rod 32. The auxiliary rotating rod 32 is used to drive the rotating block 31 and the threaded rod 15 to rotate more effortlessly. Anti-detachment balls 33 are symmetrically fixedly connected to both ends of the auxiliary rotating rod 32. The anti-detachment balls 33 play a limiting and blocking role for the palm of the worker holding the auxiliary rotating rod 32.
[0020] like Figure 1 As shown, this embodiment provides a sawing machine, which includes the aforementioned fixed fixture.
[0021] Working principle of this utility model: When the fixed fixture on the saw encounters a situation where the front and rear workpieces have a large difference in volume, a counterclockwise steering force is applied to the drive bolt 233. The drive bolt 233, rotating counterclockwise in the drive hole, will drive the U-shaped drive block 232 to move towards the drive hole. During the above process, the cross-shaped force bar 234 and the locking bar 236 will gradually move away from the strip lifting block 22 under the action of the return spring 235. When both locking bars 236 are disengaged from the locking hole, a vertical force is applied to the strip lifting block 22. When the clamping plate 14 is close to the workpiece and the locking hole is aligned with the locking bar 236, the drive bolt 233 is rotated clockwise. The drive bolt 233, rotating clockwise in the drive hole, will drive the two cross-shaped force bars 234 and the two locking bars 236 to move towards the strip lifting block 22 through the U-shaped drive block 232. When both locking bars 236 are inserted into the locking hole, the adjustment of the strip lifting block 22 is completed. The above steps reduce the time of rotating the threaded rod 15, simplify the operation, and improve convenience.
[0022] 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.
