[0003] When machining center fixtures process parts, they will encounter various parts that need to be clamped by special clamps, and then the clamps need to be replaced frequently to adapt to the processing requirements of different parts. However, the existing clamp replacement process is relatively complicated, and the replacement process will consume a lot of time, reducing the overall production efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a vertical machining center clamp. The technical problem to be solved by the utility model is that in order to cope with the processing of different parts, frequent replacement of clamps will consume a lot of time and reduce the overall production efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] like Figures 1-3 As shown, the specific implementation method is: by setting a threaded sleeve and an adjustment mechanism, the two threaded sleeves are brought close to each other, and then the clamping function is achieved through two clamping plates. By setting a turntable, the turntable can be rotated to adjust the required clamping plate, thereby reducing the time for replacing the clamping plate.

[0008] In a preferred embodiment, each of the driving mechanisms includes a second motor, and each second motor is fixedly installed on the top surface of the corresponding threaded sleeve.

A spring is jointly installed between the bottom end of each sliding column and the bottom wall of the corresponding spring. Baffles are fixedly installed inside the sleeve and on the outside of the sliding column.

[0011] In a preferred embodiment, a chute is formed on the top surface of the base, and each threaded sleeve is slidably connected to the chute.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Refer to Figures 1-3 , a fixture for a vertical machining center, including a base 1, two threaded sleeves 6 are symmetrically and slidably connected to the top surface of the base 1, the base 1 drives the sliding of the two threaded sleeves 6 through an adjusting mechanism, a turntable 7 is rotatably connected to the top surface of each threaded sleeve 6, each threaded sleeve 6 drives the rotation of the turntable 7 through a driving mechanism, a plurality of clamping plates 8 are elastically connected to the outside of each turntable 7, and the models of each clamping plate 8 are inconsistent.

[0023] As Figures 1-3 shown, the specific implementation method is as follows: by setting the threaded sleeve 6 and the adjusting mechanism, the two threaded sleeves 6 are made to approach each other, and then the clamping function is realized through the two clamping plates 8. By setting the turntable 7, the required clamping plate 8 can be rotated to adjust, reducing the time for replacing the clamping plate 8.

[0024] Each driving mechanism includes a second motor 11, and each second motor 11 is fixedly installed on the top surface of the corresponding threaded sleeve 6. A gear 10 is installed on the output shaft of each second motor 11. A gear ring 9 is installed on the bottom surface of each turntable 7, and each gear 10 meshes with the corresponding gear ring 9.

[0025] By driving the second motor 11, the gear 10 is driven to rotate. Since the pitch diameter of the gear 10 is smaller than the diameter of the gear ring 9, the turntable 7 can be driven to rotate slowly, which makes it easier to align the two clamping plates 8.

[0026] The adjusting mechanism includes two support seats 2, and the two support seats 2 are symmetrically installed on the top surface of the base 1 by screws. The two support seats 2 are jointly rotatably connected with a double-headed screw 5, and each threaded sleeve 6 is threadedly connected with the double-headed screw 5.

[0027] Due to the detachable design of the threaded sleeve 6, it is convenient to replace when the double-headed screw 5 is worn.

[0028] A plurality of sleeves 12 are fixedly installed on the outer side of each turntable 7. A sliding column 13 is slidably connected in each sleeve 12, and each clamping plate 8 is fixedly installed at one end of the corresponding sliding column 13. A spring 14 is jointly installed between the bottom end of each sliding column 13 and the bottom wall of the corresponding spring 14. Baffles 15 are fixedly installed inside the sleeve 12 and on the outer side of the sliding column 13.

[0029] Due to the arrangement of the spring 14, when the clamping plate 8 clamps the part, the spring 14 can buffer it, and at the same time reduce the vibration and impact that may occur during processing.

[0030] A chute 4 is opened on the top surface of the base 1, and each threaded sleeve 6 is slidably connected with the chute 4.

[0031] Since the chute 4 is a square chute, the threaded sleeve 6 is limited and cannot rotate, and then linear movement is carried out.

[0032] A first motor 3 is fixedly installed on the outer side of one of the support seats 2, and the output shaft of the first motor 3 passes through the support seat 2 and is connected to the double-headed screw 5.

[0033] When the utility model is used, first, the second motor 11 is started to drive the gear 10 to rotate. Since the gear 10 meshes with the gear ring 9, the turntable 7 is driven to rotate synchronously through the rotation of the gear ring 9. Since a plurality of different clamping plates 8 are installed on the outer side of the turntable 7, the appropriate clamping plate 8 can be selected according to the shape of the part to be processed. The two turntables 7 are rotated respectively until the two clamping plates 8 are aligned and then the rotation is stopped;

[0034] Then, the first motor 3 is started to drive the double-headed screw 5 to rotate. Since each threaded sleeve 6 is threadedly connected with the double-headed screw 5, the two threaded sleeves 6 slide towards each other to drive the two clamping plates 8 to clamp the part. At the same time, since a sleeve 12 is installed on the outer side of each turntable 7, and a spring 14 is jointly installed between the sliding column 13 and the sleeve 12, the impact and vibration of the part during processing can be buffered by the spring 14.

[0035] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
