[0018] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0020] like Figure 1 to Figure 4 As shown, a quick clamping fixture comprises: a base plate 1, ten clamp frames are arranged on the base plate 1, and the clamp frames are installed opposite to each other in pairs, and the clamp frames comprise: a support column 2, a locking fixing block 3, a locking claw 4, and a clamping block 5. A countersunk groove is opened on the support column 2, and two screw holes are opened in the countersunk groove. A screw hole is opened in the middle of the locking fixing block 3, and two countersunk holes are opened on both sides. The hole spacing between the two countersunk holes is the same as the hole spacing between the screw holes on the countersunk groove. The locking fixing block 3 is connected to the support column 2 by a fixing block screw 6, and the protruding cutting edge part of the upper end of the locking claw 4 presses the clamping block 5 to the top of the support column, and a screw hole is opened at the lower end of the locking claw 4, and the locking claw 4 is connected to the locking fixing block 3 by a claw screw 7.

[0021] Adjust the position of the fixture rack on the chassis 1 according to the product. Place the product on the clamping block 5. Put the locking and fixing block 3 into the sinking groove of the support column 2. Do not tighten the fixing block screw 6 temporarily. Install the locking claw 4. Adjust the position of the locking and fixing block 3 according to the actual situation of the product. After ensuring that the locking claw 4 has a locking stroke of more than 0.1 mm after being stressed, tighten the fixing block screw 6 to lock and fix the locking and fixing block 3, and then tighten the claw screw 7 to lock and fix the locking claw 4, then the workpiece can be reliably locked.

[0022] The aperture of the screw hole on the locking claw 4 is 1 mm larger than the diameter of the claw screw 7. During the locking process, the locking claw 4 generates an inward displacement, and at the same time generates a downward displacement under the action of the inclined surface of the locking and fixing block 3 to lock the workpiece.

[0023] The clamping block 5 for clamping the left end of the product is a block with a clamping surface in a shape of a slash.

[0024] The clamping block 5 for clamping the middle section of the product is a block with a clamping surface in an L shape.

[0025] The clamping block 5 for clamping the right end of the product is an inverted trapezoidal block.

[0026] The locking claw 4 is provided with a plurality of vertically arranged screw holes. The locking claw 4 can be connected to the locking and fixing block 3 with screw holes of different heights according to needs, so as to adjust the height of the locking claw 4 to adapt to the clamping needs of different products.

[0027] The edge part protruding from the upper end of the locking claw 4 is a serrated edge. The serrated edge will not slip during locking.

[0028] When the utility model is in use: Adjust the position of the fixture rack on the chassis 1 according to the product. Select the clamping block 5 adapted to the product to be clamped. Place the product on the clamping block 5. Put the locking and fixing block 3 into the sinking groove of the support column 2. Do not tighten the fixing block screw 6 temporarily. Install the locking claw 4. Adjust the position of the locking and fixing block 3 according to the actual situation of the product. After ensuring that the locking claw 4 has a locking stroke of more than 0.1 mm after being stressed, tighten the fixing block screw 6 to lock and fix the locking and fixing block 3, and then tighten the claw screw 7 to lock and fix the locking claw 4, then the workpiece can be reliably locked.

[0029] The above has made an exemplary description of the utility model in conjunction with the drawings. Obviously, the specific implementation of the utility model is not limited by the above methods. As long as various improvements are made by adopting the method concept and technical solution of the utility model, or directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
