[0027] At present, a vise is used to clamp and mill the block blank in a single piece, but there is a problem of instability when clamping the block blank.

[0028] In view of the above problems, the present application provides a block blank 6 fixture, such as Figure 1 and Figure 2 As shown, the block stock 6 clamp includes a base 1, an adjusting block 3 and a locking block 4. The base 1 is provided with a placement position 5 for placing the block stock 6. The adjusting block 3 and the locking block 4 are respectively located at the two ends of the placement position 5 in the first direction. The base 1 is provided with a first limiting portion 51 located at the two ends of the placement position 5 in the second direction. The base 1 is provided with a second limiting portion 52 located at one end of the placement position 5 close to the locking block 4. The adjusting block 3 can slide along the first direction on the base 1. The adjusting block 3 is provided with a locking piece, which can fix the adjusting block 3 on the base 1. The locking block 4 can move in a third direction and can press the block stock 6 located on the placement position 5. The first direction is perpendicular to the second direction, and the third direction is perpendicular to the plane where the first direction and the second direction are located.

[0029] Move the locking block 4 away from the placement position 5, and place the block stock 6 in the placement position 5 on the base 1. The three ends of the block stock 6 are respectively against the second limiting part 52 and the two first limiting parts 51, and the other end is against them through the adjusting block 3. The adjusting block 3 is fixed on the base 1 by a locking piece, and the locking block 4 is pressed on the block stock 6. At this time, the block stock 6 is completely limited, and the block stock 6 is not firmly clamped in the single-piece clamping processing mode, so that the block stock 6 will not be displaced perpendicular to the clamping direction, causing the product to fall and be damaged.

[0030] In some embodiments of the present application, Figure 1 As shown, a plurality of placement positions 5 are arranged on the base 1 , two placement positions 5 form a group, and the locking block 4 is located between two placement positions 5 in the same group.

[0031] By providing a plurality of placement positions 5, a plurality of block blanks 6 can be clamped at the same time for operations such as milling, which has a higher production efficiency than using a vise to clamp and process only one product at a time.

[0032] In some embodiments of the present application, Figures 1 to 3 As shown, a locking slot 2 extending along a first direction is provided on the base 1, the locking member includes a locking screw 31, and a threaded hole 32 corresponding to the locking slot 2 is provided on the adjustment block 3. The locking screw 31 passes through the locking slot 2 and is threadedly connected to the threaded hole 32.

[0033] The locking screw 31 passes through the locking barrel groove and is connected to the threaded hole 32 on the adjustment block 3. The adjustment block 3 can be fixed or loosened relative to the base 1 by turning the locking screw 31. The structure is simple and the use is convenient and labor-saving.

[0034] In some embodiments of the present application, the block blank 6 clamp further includes a driving mechanism, which is connected to the locking block 4 and can drive the locking block 4 to move in the third direction.

[0035] The driving mechanism may be a manual or automatic mechanism to drive the locking block 4 to move in the third direction to press or release the block-shaped blank 6 .

[0036] In some embodiments of the present application, Figure 1 As shown, the driving mechanism includes a lifting driver 7, and a receiving cavity for receiving the lifting driver 7 is provided on the base 1. The lifting driver 7 is arranged in the receiving cavity and is connected to the base 1. The output end of the lifting driver 7 passes through the base 1 and is connected to the locking block 4. The output end of the lifting driver 7 can drive the locking block 4 to move in the third direction and can make the locking block 4 press against the block blank 6 located on the placement position 5.

[0037] The use of the lifting drive 7 can save manpower, and there is no need to manually press the block blank 6.

[0038] In some embodiments of the present application, the lifting drive 7 includes a pneumatic cylinder or an electric cylinder.

[0039] It should be noted that the lifting driver 7 can be a device such as a pneumatic cylinder, an electric cylinder or an oil cylinder, which can drive the locking block 4 to move in the third direction.

[0040] In some embodiments of the present application, Figure 1 and Figure 2 As shown, a bevel block 41 is provided at one end of the locking block 4 close to the placement position 5 , and when the locking block 4 presses against the block material 6 located at the placement position 5 , the bevel block 41 abuts against the end of the block material 6 away from the adjustment block 3 .

[0041] The above-mentioned bevel block 41 serves as a transition structure between the clamp and the clamped object. The bevel block 41 can well disperse stress, prevent sliding, reduce material damage, etc. through its inclined surface structure, thereby improving the clamping performance and applicability of the clamp.

[0042] In some embodiments of the present application, the bevel block 41 is connected to the locking block 4 via a return spring (not shown in the figure).

[0043] Using a reset spring to connect the bevel block 41 to the locking block 4 can achieve adaptive clamping, absorb shape differences, and make the bevel block 41 better adapt to the surfaces of objects of different shapes. It can also buffer the force applied by the clamp and reduce the clamping force to avoid the object being crushed due to excessive force. Compared with direct connection, indirect connection through a reset spring can better reduce the pressure of the bevel block 41 on the surface of the object, thereby reducing the risk of material damage. It can also absorb deformation to a certain extent to prevent the bevel block 41 from getting stuck on the surface of the object. When the bevel block 41 needs to be replaced, it is easier to achieve through a spring connection.

[0044] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
