[0022] 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.
[0023] This utility model provides, for example Figure 1-4 shown
[0024] A quick-access machining fixture for mechanical parts includes a base plate 1. Corresponding columns 2 are provided on both sides of the top of the base plate 1. The bottom of the two columns 2 is fixedly connected to the top of the base plate 1. Turntables 3 are correspondingly provided on the inner sides of the two columns 2. The two turntables 3 can rotate by the drive of motors inside the two columns 2. Support blocks 4 are provided at the bottom of the inner sides of the two turntables 3, and the support blocks 4 are fixedly connected to the bottom of the inner sides of the turntables 3. A support plate 5 is provided above the two support blocks 4. The two ends of the support plate 5 are fixedly connected to the two support blocks 4 by screws. Three evenly spaced fixing seats 6 are provided on the support plate 5. The fixing seats 6 are rotatably connected to the support plate 5. A base 7 is provided in the interval between every two fixing seats 6. The two ends of the base 7 are clamped and fixed by the fixing seats 6. A lower clamping block 8 is provided above the base 7, and an upper clamping block 9 is provided above the lower clamping block 8. Two clamping grooves are provided on the top surface of the lower clamping block 8 and the bottom surface of the upper clamping block 9. Two workpieces can be clamped simultaneously by the lower clamping block 8 and the upper clamping block 9. The tightness of the clamping between the lower clamping block 8 and the upper clamping block 9 is adjusted by screws 10. The upper clamping block 9 is equipped with an adjustment component, which is used to facilitate clamping workpieces of different sizes and enhance the applicability of the fixture. The adjustment component includes an upper clamping plate 14 and a screw cap 24. In use, the base 7 is fixedly installed on the support plate 5 by the fixing seat 6. Then, the screws 10 are screwed outward to increase the distance between the lower clamping block 8 and the upper clamping block 9. Next, the workpiece is placed into the clamping groove on the lower clamping block 8. Then, the screws 10 are screwed downward to move the upper clamping block 9 downward to reduce the distance between it and the lower clamping block 8, and finally, the workpiece is clamped tightly to complete the fixation.
[0025] like Figure 2 and Figure 3 As shown, the lower clamping block 8 is divided into a central lower main clamping plate 11 and two side lower clamping plates 12 at the center of the two clamping grooves. The bottom of the lower main clamping plate 11 is fixedly connected to the top of the base 7. The side lower clamping plates 12 can move. At this time, the height of the base 7 is higher than the height of the fixed seat 6, so that the side lower clamping plates 12 are not blocked by the fixed seat 6 when moving. The upper clamping block 9 is divided into a central upper main clamping plate 13 and two side upper clamping plates 14 at the center of the two clamping grooves. The upper main clamping plate 13 is adjusted by screws 10 to adjust the distance between the upper main clamping plate 13 and the lower main clamping plate 11. The side upper clamping plates 14 can move. Figure 2 and Figure 3 As shown, the outer sides of the two lower clamping plates 12 and the upper clamping plate 14 are provided with corresponding connecting blocks 15. The connecting blocks 15 are fixedly connected to the outer sides of the lower clamping plates 12 and the upper clamping plate 14, respectively. The connecting blocks 15 on the lower clamping plate 12 are positioned slightly upwards, and the connecting blocks 15 on the upper clamping plate 14 are positioned slightly downwards. Each connecting block 15 has a through hole 16 that passes through it vertically. Figure 2 and Figure 3As shown, a sliding rod 18 is provided in the through hole 16 of the corresponding upper and lower connecting blocks 15. The diameter of the sliding rod 18 is smaller than the diameter of the through hole 16, so the sliding rod 18 can slide up and down in the through hole 16. A limiting block 17 is provided at the top of the sliding rod 18, and the bottom of the limiting block 17 is fixedly connected to the bottom of the sliding rod 18. The diameter of the limiting block 17 is larger than the diameter of the through hole 16, so the limiting block 17 cannot pass through the through hole 16, and the limiting block 17 is located above the uppermost connecting block 15. A gravity block 19 is provided at the bottom of the sliding rod 18, and the top of the gravity block 19 is fixedly connected to the bottom of the sliding rod 18. The diameter of the gravity block 19 is larger than the diameter of the through hole 16, so the gravity block 19 also cannot pass through the through hole 16. Hole 16, and gravity block 19 is located below the lowest connecting block 15. Gravity block 19 is used to allow slide rod 18 to fall under gravity. It is worth noting that under the influence of gravity block 19, the minimum height of slide rod 18 and gravity block 19 falling under gravity is higher than the fixed base 6, so that the use of slide rod 18 and gravity block 19 will not be affected by fixed base 6. Through this setting, the lower clamping plate 12 and the upper clamping plate 14 can be linked, so that when the upper clamping plate 14 moves left and right, the lower clamping plate 12 will move synchronously. At the same time, when the upper clamping plate 14 moves up and down, this setting can also play a guiding role, making the up and down movement of the upper clamping plate 14 more stable. Figure 2 and Figure 3 As shown, the upper clamping plate 14 has a through-hole threaded hole 22 on its side. The end of the threaded hole 22 extends into the upper main clamping plate 13. A screw 23 is screwed into the threaded hole 22. The screw 23 can be screwed onto the upper main clamping plate 13 through the threaded hole 22. A screw cap 24 is provided on the outer end of the screw 23. The screw cap 24 is fixedly connected to the outer end of the screw 23. By rotating the screw cap 24, the distance between the upper clamping plate 14 and the upper main clamping plate 13 can be adjusted. At this time, the lower clamping plate 12 will also be adjusted synchronously. Figure 3 As shown, the bottom of the lower clamping plate 12 is provided with a slider 21, the top of the slider 21 is fixedly connected to the bottom of the lower clamping plate 12, and the top surface of the base 7 is provided with a groove 20 corresponding to the slider 21. The slider 21 and the groove 20 can make the left and right movement of the lower clamping plate 12 more stable, and at the same time play a guiding role to avoid misalignment. Figure 2As shown, guide holes 25 penetrating the upper clamping plate 14 are provided on both sides of the threaded hole 22. Positioning rods 26 corresponding to the guide holes 25 are provided on the side of the upper main clamping plate 13. The positioning rods 26 are fixedly connected to the side of the upper main clamping plate 13. The upper clamping plate 14 can slide on the positioning rods 26 on the side of the upper main clamping plate 13 through the guide holes 25. This design prevents the upper clamping plate 14 from rotating and enhances the stability of the movement adjustment. In use, the screw 23 is removed by rotating the screw cap 24. Then, the upper clamping plate 14 is moved, and the lower clamping plate 12 moves synchronously. This operation adjusts the width of the clamping groove. After adjustment, the workpiece is placed in the clamping groove, and then the screw 23 is screwed into the threaded hole 22, so that the screw cap 24 presses against the upper clamping plate 14. This design facilitates the clamping of workpieces of different sizes, enhancing the applicability of the fixture.
