Description

Technical Field

[0001] The utility model relates to the technical field of mechanical fixtures, in particular to a mechatronic adaptive mechanical fixture. Background Art

[0002] Mechatronic mechanical fixtures play an important role in production applications. When in use, compared with traditional mechanical fixtures, mechatronic mechanical fixtures mainly combine mechanical and electrical technologies and have a high degree of automation. The fixture can hold and fix the workpiece firmly, preventing the workpiece from moving or deforming during the processing, thereby improving the processing accuracy and stability.

[0003] When the fixture in the mechatronic mechanical fixture is in use, it generally can only hold and fix workpieces with a specific height. For workpieces with a higher height, the fixture can only hold the lower position at one end of the workpiece. Compared with the overall height of the workpiece, the fixing degree of the fixture to the workpiece is insufficient, and it cannot effectively adapt to the change of the workpiece height. As a result, during the processing of the workpiece, the workpiece is likely to break away from the clamping of the fixture. Secondly, the clamped part of the workpiece is prone to large stress and deformation. If you want to make the fixture adapt to the height of the workpiece, you need to replace the corresponding fixture, but the process of replacing the fixture is more cumbersome.

[0004] Based on the above situation, it is necessary to design a mechatronic adaptive mechanical fixture to solve the above problems. Summary of the Utility Model

[0005] The utility model provides a mechatronic adaptive mechanical fixture to solve the problems of the mechatronic adaptive mechanical fixture in the prior art.

[0006] The technical problems solved by the utility model are realized by the following technical solutions:

The rack is fixedly connected to a surface of the first clamping block away from the central axis of the processing plate, and the rack meshes with the rotating gear. An output end of the first motor is connected to the worm.

[0009] Preferably, the second driving assembly includes a bidirectional threaded rod, a first gear, a second gear, and a second motor. Two ends of the bidirectional threaded rod are respectively connected to two sliding bases in the same vertical plane. The first gear is connected to one end of the bidirectional threaded rod.

[0010] Preferably, an installation groove is formed in the second clamping block. A telescopic rod is connected in the installation groove. A movable end of the telescopic rod is connected to a grooved block. An inclined groove is formed in the grooved block. An extrusion rod is slidably connected in the inclined groove.

[0013] Preferably, scale bars are provided on a side wall of the first clamping block and on one side of the slide rail groove.

[0014] The beneficial effects of the present utility model are as follows: The second clamping block is slidably connected to the first clamping block capable of clamping and fixing a workpiece. As the second clamping block slides, the first clamping block extends the height of the second clamping block, increasing the vertical height of the first clamping block and the second clamping block together, and also making the surfaces of the first clamping block and the second clamping block more dispersed. When the first clamping block and the second clamping block come into contact with a workpiece with a higher height, they can adapt to different workpiece heights, making the workpiece more stable when being clamped.

Detailed implementation manners

[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the following further elaborates the present utility model in conjunction with specific illustrations.

[0025] Refer to Figures 1 - 7As shown in the figure, a mechatronic adaptive mechanical fixture includes a processing base 1. A processing plate 2 is connected to the processing base 1. A number of slide rail grooves 3 are provided on the processing plate 2 at equal intervals around the central axis of the processing plate 2. The number of the several slide rail grooves 3 is a multiple of 2. A sliding base 4 is slidably connected to the slide rail groove 3. A clamping block 5 is connected to the sliding base 4. A sliding groove 6 perpendicular to the surface of the processing plate 2 is provided on the clamping block 5. A clamping block 7 is slidably connected to the sliding groove 6. The vertical height of the clamping block 7 is not less than the depth of the sliding groove 6. The surface of the clamping block 5 close to the central axis of the processing plate 2 and the surface of the clamping block 7 close to the central axis of the processing plate 2 are in the same vertical plane. A driving component 1 is provided on the clamping block 5 for driving the clamping block 7 to slide. A driving component 2 is provided on the processing base 1 for driving several sliding bases 4 to move. When the above structure is in use, first place the workpiece to be clamped at a suitable position on the processing plate 2, then start the driving component 2 to move the sliding base 4 to the outer wall of the workpiece and make the clamping block contact the outer wall of the workpiece. When the height of the workpiece is relatively high, start the driving component 1 at this time to make the clamping block 5 slide on the clamping block 7. At this time, the clamping block 5 extends the height of the clamping block 7, so that the vertical height of the clamping block 7 and the clamping block 5 together is increased, and the surfaces of the clamping block 5 and the clamping block 7 are in a more dispersed state. Therefore, when clamping the outer wall of the workpiece, the vertical height during clamping can be increased, so that when the workpiece is stressed, the clamping block 5 and the clamping block 7 can better bear the force of the workpiece. It can be self-adjusted according to the height of different workpieces to achieve adaptability to workpiece clamping. At the same time, the clamping surfaces of the clamping block 5 and the clamping block 7 are in a larger area, so that the clamped part of the workpiece will not easily deform. Through the sliding and extending relationship between the clamping block 5 and the clamping block 7, when clamping a workpiece with a relatively high height, it will be more stable.

[0026] Refer to Figure 6As shown in the figure, the first driving component includes a rack 8, a driving shaft 9 rotatably connected to the first clamping block 5, a rotating gear 10 fixedly connected to the driving shaft 9, a worm gear 11, a worm 12 rotatably connected to the first clamping block 5 and meshing with the worm gear 11, and a first motor 120 provided on the first clamping block 5. The rack 8 is fixedly connected to a surface of the first clamping block 5 away from the central axis of the processing plate 2, and the rack 8 meshes with the rotating gear 10. The output end of the first motor 120 is connected to the worm 12. During use, when the first motor 120 is started, the output end of the first motor 120 drives the worm 12 to rotate, thereby driving the worm gear 11 to rotate through the worm 12, then driving the driving shaft 9 to rotate, and then driving the rotating gear 10 fixedly connected to the driving shaft 9 to rotate, and then driving the rack 8 meshing with it to rotate. The rack 8 will drive the second clamping block 7 fixedly connected to it to move. As the rotation direction of the driving shaft 9 is different, the second clamping block 7 will slide in different directions accordingly. When the second clamping block 7 slides upward, at this time, the vertical height of the second clamping block 7 and the first clamping block 5 together increases. Therefore, when clamping the outer wall of the workpiece, the vertical height during clamping can be increased, so that when clamping a workpiece with a higher height, it is more stable.

[0027] Referring to Figure 3 As shown in the figure, further, the second driving component includes a bidirectional threaded rod 13, a first gear 14, a second gear 15, and a second motor 16. The two ends of the bidirectional threaded rod 13 are respectively connected to two sliding bases 4 in the same vertical plane. The bidirectional threaded rod 13 is rotatably connected to the processing plate 2. The bidirectional threaded rod 13, the first gear 14, the second gear 15, and the second motor 16 are all in a certain number, and the number corresponds to half of the number of the sliding bases 4. The first gear 14 is connected to one end of the bidirectional threaded rod 13. The second gear 15 is connected to the processing base 1. The output end of the second motor 16 is connected to the second gear 15. The second gear 15 meshes with the first gear 14. During use, when the second motor 16 is started, the output end of the second motor 16 drives the second gear 15 to rotate, thereby driving the first gear 14 to rotate through the second gear 15, and finally driving the bidirectional threaded rod 13 to rotate. The bidirectional threaded rod 13 will drive the two sliding bases 4 threadedly connected to it to move in opposite or away directions, thereby driving the first clamping block 5 to clamp and fix the workpiece. The plurality of bidirectional threaded rods 13 are independently controlled. Therefore, the first clamping block 5 and the second clamping block 7 can clamp and fix workpieces with different shapes.

[0028] Furthermore, since the clamping block II 7 extends the height of the clamping block I 5, the supporting force received by the upper end of the clamping block II 7 is smaller than that of the clamping block I 5. Therefore, in order to ensure the close contact relationship between the end of the clamping block II 7 away from the workpiece and the side wall of the workpiece, an installation groove 17 is provided in the clamping block II 7. An expansion rod 18 is connected in the installation groove 17. The movable end of the expansion rod 18 is connected with a grooved block 19. An inclined groove 20 is provided in the grooved block 19. A pressing rod 21 is slidably connected in the inclined groove 20. A pressing block 22 is slidably connected to the upper end surface of the clamping block II 7. The pressing block 22 is connected with the pressing rod 21. During use, the movable end of the expansion rod 18 will drive the grooved block 19 to move in the vertical direction. When driving the grooved block 19 to move upward, the pressing rod 21 will move along the opening direction of the inclined groove 20, thereby driving the pressing block 22 to move horizontally, and then clamping the workpiece. By pressing the workpiece with the pressing block 22, the problem that the clamping between the end of the clamping block II 7 away from the workpiece and the workpiece is not tight enough can be avoided.

[0029] Referring to Figure 4 As shown, furthermore, a trapezoidal clamping member 23 is connected below the end of the clamping block I 5 close to the central axis of the processing plate 2. The trapezoidal clamping member 23 is composed of a plurality of clamping plates 24 with unequal lengths. The lengths of the plurality of clamping plates 24 gradually decrease from bottom to top, and the surfaces of the plurality of clamping plates 24 away from the central axis of the processing plate 2 are in the same vertical plane. The trapezoidal clamping member 23 can be used to accurately clamp workpieces with a small height, replacing the clamping block I 5 to clamp and fix some workpieces. When in use, the trapezoidal clamping member 23 can be disassembled and installed by itself according to the use scenario, and the specific implementation method will not be elaborated in detail.

[0030] Finally, in order to facilitate observing the moving distances of the clamping block I 5 and the clamping block II 7, scale bars 25 are provided on the side wall of the clamping block I 5 and on one side of the slide rail groove 3.
