An inverted T-shaped groove 10 is formed on the top surface of the guide rail 9 along its length. A slider 11 is slidably installed in the inverted T-shaped groove 10. The slider 11 is a rectangular block. A movable seat 12 supported on the top surface of the guide rail 9 is provided directly above the slider 11. A stepped hole 13 is formed on the bottom surface of the slider 11, which communicates with the top port of the inverted T-shaped groove 10. A locking screw 14 passes through the stepped hole 13, passing through the top port of the inverted T-shaped groove 10 and the movable seat 12 in sequence. A locking nut 15 is connected to the extension end of the locking screw 14.

[0035] A vertical groove 16 is provided on the top surface of the movable seat 12 and to the left of the locking screw 14. A horizontal groove 17 is provided on the left end face of the movable seat 12 and communicates with the vertical groove 16. A threaded rod 18 is fixed at the bottom of the horizontal groove 17 and extends upward through the vertical groove 16. A nut 19 is threadedly connected to the upper end of the threaded rod 18.

[0036] A pressure block 20 is fitted around the threaded rod 18. The pressure block 20 slides in conjunction with the vertical groove 16. An inclined surface 21 is provided at the lower left end of the pressure block 20. A vertical spring 22 is also fitted around the threaded rod 18. The upper end of the vertical spring 22 is fixed to the bottom surface of the pressure block 20, and the lower end of the vertical spring 22 is fixed to the bottom of the horizontal groove 17. Under the elastic force of the vertical spring 22, the top surface of the pressure block 20 abuts against the bottom surface of the nut 19.

[0037] A clamping block 23 is slidably installed in the horizontal groove 17 of the movable seat 12. A wedge-shaped surface is provided at the upper end of the right side of the clamping block 23. An installation plate is fixed on the top surface of the left end of the clamping block 23. A horizontal spring 24 is fixed between the installation plate and the left end face of the movable seat 12. Under the elastic force of the horizontal spring 24, the wedge-shaped surface of the clamping block 23 always abuts against the inclined surface 21 of the pressure block 20.

[0038] A stop is provided on the right end face of the upright plate 3. A plurality of pads 8 are fixed on the top surface of the bottom plate 2, and the top surfaces of the pads 8 are flush with the stop. A vertically arranged through hole is provided in the pressure block 20, and the pressure block 20 is sleeved on the outside of the threaded rod 18 through the through hole.

[0039] The working process of this utility model is as follows:

[0040] S1, the workers hoisted out a... Figures 1-2 The plate 1 shown is inserted into the stop of the upright plate 3 at its left end, and the plate 1 is supported on the top surface of the pad block 8.

[0041] S2, the worker pushes the movable seat 12 to the left with his hand, the movable seat 12 moves to the left along the top surface of the guide rail 9, at the same time, the movable seat 12 drives the sliding block 11 to move to the left along the length direction of the inverted T-shaped groove 10, the movable seat 12 also drives the pressing block 20, the locking screw 14, the threaded rod 18 and the clamping block 23 to move to the direction of the plate 1 synchronously, when the worker observes that the clamping block 23 approaches the plate 1, the worker stops sliding the movable seat 12;

[0042] S3, the worker tightens the locking nut 15, under the threaded connection force between the locking nut 15 and the locking screw 14, the movable seat 12 is locked and fixed on the top surface of the guide rail 9;

[0043] S4, the worker rotates the nut 19 downward, the nut 19 moves downward along the threaded rod 18, the nut 19 presses the pressing block 20 downward, the pressing block 20 moves downward along the vertical groove 16 and compresses the vertical spring 22, at the same time, the pressing block 20 drives the clamping block 23 to move to the left along the horizontal groove 17, the clamping block 23 drives the mounting plate to move to the left, the mounting plate stretches the horizontal spring 24 to the left, when the worker can no longer rotate the nut 19, it indicates that the plate 1 is just clamped and fixed between the clamping block 23 and the vertical plate 3, so as to realize the work fixture of the plate 1;

[0044] S5, after the plate 1 is fixed, the worker can drill and mill the plate 1 through the machining machine tool;

[0045] S6, taking away the plate 1: the worker first rotates the nut 19 upward, under the elastic recovery of the vertical spring 22, the pressing block 20 moves upward along the vertical groove 16, at the same time, the clamping block 23 moves to the right under the restoring force of the horizontal spring 24, the clamping block 23 is separated from the plate 1; then the worker loosens the locking nut 15, the movable seat 12 is no longer locked and fixed on the guide rail 9, then the worker slides the movable seat 12 to the right, the movable seat 12 drives the sliding block 11 to move to the right along the inverted T-shaped groove 10, when it is observed that the clamping block 23 and the plate 1 have a large gap, the worker stops sliding the movable seat 12; finally the worker hoists away the plate 1.

[0046] As can be seen from steps S2-S4, the worker only needs to slide the movable seat 12 to the left, so that the movable seat 12 quickly moves to the plate 1 along the guide rail 9, and then the clamping block 23 in the movable seat 12 quickly enters the clamping station; then the locking nut 15 is tightened to lock and fix the movable seat 12 on the guide rail 9; finally the nut 19 is rotated downward, so that the plate 1 is clamped and fixed by the clamping block 23. It can be seen that, compared with the work fixture clamp shown in Figures 3-4 the worker does not need to rotate the handle 7 many times to fix the plate 1 between the vertical plate 3 and the clamping plate 6, so the fixing time of the plate 1 is greatly shortened, the work fixture efficiency of the plate 1 is greatly shortened, and the subsequent machining efficiency of the plate is improved.

[0047] It should be pointed out finally that: the above only for the preferred embodiments of the utility model have, and do not for limiting the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model, should be included in the protection scope of the utility model.
