A plurality of spaced-apart fixing blocks are detachably mounted on the plurality of first positioning mounting holes. Each fixing block has a positioning groove on its inner top side. The tooling base plate has a plurality of rows of second positioning mounting holes. A plurality of equal-height pads and a plurality of clamping devices are mounted on the plurality of rows of second positioning mounting holes. The plurality of clamping devices are spaced apart on the other side of the tooling base plate and correspond one-to-one with the fixing blocks. Each clamping device includes a movable groove, an OK clamp, and a movable block. The movable groove faces the fixing block, and the OK clamp is movably mounted on the movable groove via the movable block. The OK clamp of each clamping device is opposite to the positioning groove of the corresponding fixing block. A plurality of equal-height pads are spaced apart between each clamping device and the corresponding fixing block. The height of the equal-height pads is lower than the height of the OK clamp and the positioning groove of the fixing block.

[0006] Furthermore, the tooling base plate includes a left plate, a middle plate, and a right plate, and fixing blocks, leveling blocks, and clamping devices are installed on the left plate, the middle plate, and the right plate.

[0007] Furthermore, the fixing block is positioned between the first positioning mounting hole of the tooling base plate and the first positioning pin, and the fixing block and the positioning pin are fixed together by the first fixing screw.

[0008] Furthermore, a limit block is installed at the outer end of the fixing block on the left plate by screws.

[0009] Furthermore, the clamping device is positioned between the second positioning mounting hole of the tooling base plate and the second positioning pin, and the clamping device is fixed to the second positioning pin by the second fixing screw.

[0010] Furthermore, the OK clamp of the clamping device is locked to the movable groove by a locking screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model can quickly and stably clamp parts of different sizes by simply adjusting the installation position of the fixing block on the tooling base plate and the clamping device. The operation is simple and convenient, which can reduce the dependence on the worker's skills. At the same time, compared with vise clamping, it can effectively shorten the product changeover and debugging time, thereby improving the machine tool utilization rate. Attached Figure Description

[0017] Example

[0018] Please see Figure 1 , Figure 2This embodiment provides a novel universal combined fixture, including a fixture base plate 1. A plurality of first positioning mounting holes 11 are arranged in a row on one side of the fixture base plate 1. A plurality of spaced fixing blocks 2 are detachably mounted on the plurality of first positioning mounting holes 11. Each fixing block 2 has a positioning groove 21 on its inner top side. The fixture base plate 1 has a plurality of rows of second positioning mounting holes 12. A plurality of equal-height pads 3 and a plurality of clamping devices 4 are mounted on the plurality of rows of second positioning mounting holes 12. The clamping devices 4 are spaced apart on the fixture base plate. On the other side of plate 1, corresponding one-to-one with fixed blocks 2, clamping device 4 includes movable groove 41, OK clamp 42, and movable block 43. Movable groove 41 is set facing fixed block 2, and OK clamp 42 is movably set on movable groove 41 through movable block 43. The OK clamp 42 of each clamping device 4 is set opposite to the positioning groove 21 of the corresponding fixed block 2. Several equal-height pads 3 are distributed at intervals between each clamping device 4 and the corresponding fixed block 2. The height of the equal-height pads 3 is lower than the height of the OK clamp 42 and the positioning groove 21 of the fixed block 2. During clamping, the part is placed on several equal-height pads 3, one side is positioned by the positioning groove 21 of the fixed block 2, and the other side is clamped by the OK clamp 42 of the clamping device 4.

[0019] The OK clamp 42 of the clamping device 4 is locked to the movable groove 41 by a locking screw 44. By loosening the locking screw 44, the OK clamp 42 can be pushed to perform the clamping operation of the part. After clamping is completed, the locking screw 44 can be tightened.

[0020] Specifically, the tooling base plate 1 includes a left plate 13, a middle plate 14, and a right plate 15. Each of the left plate 13, middle plate 14, and right plate 15 is equipped with a fixing block 2, a leveling pad 3, and a clamping device 4. The fixing blocks 2 on the left plate 13, middle plate 14, and right plate 15 are positioned with the first positioning mounting holes 11 by first positioning pins 22, and the fixing blocks 2 and positioning pins 22 are fixed by first fixing screws 23. The clamping device 4 is positioned with the second positioning mounting holes 12 on the tooling base plate 1 by second positioning pins 45, and the clamping device 4 and second positioning pins 45 are fixed by second fixing screws 46. The fixing blocks 2 and clamping devices 4 can be installed by selecting different first positioning mounting holes 11 and second positioning mounting holes 12, thereby enabling the clamping and fixing of parts of different sizes.

[0021] The outer end of the fixing block 2 on the left plate 13 is fitted with a limit block 5 by screws for limiting the position of the part.

[0022] In summary, this new universal combination fixture can quickly and stably clamp parts of different sizes by simply adjusting the installation positions of the fixing block 2 on the fixture base plate 1 and the clamping device 4. It is simple and convenient to operate, reduces the reliance on worker skills, and compared with vise clamping, it can effectively shorten the product changeover and debugging time, thereby improving the machine tool uptime.
