These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the utility model. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In addition, in the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Therefore, the application provides a quick clamping tool, which can clamp a plurality of workpieces at one time and improve the processing efficiency.

As shown in fig. 1 to 6, a quick clamping fixture comprises a base plate 1, a fixed block 2 and a movable block 3, wherein a plurality of longitudinal first sliding grooves 11 and a plurality of transverse second sliding grooves 12 are formed in the upper surface of the base plate 1, and the upper surface of the base plate 1 is divided into a plurality of supporting positions 13 for bearing workpieces 4 by the plurality of first sliding grooves 11 and the plurality of second sliding grooves 12.

The plurality of fixing blocks 2 are respectively connected to the upper surface of the base plate 1 along the extending direction of the first chute 11 and the second chute 12, and specifically, the fixing blocks 2 can be fixed to the upper surface of the base plate 1 through connecting pieces such as screws. Thus, when the workpiece 4 is placed on the support position 13, the fixing block 2 can block the adjacent two sides of the workpiece 4, thereby performing preliminary positioning of the workpiece 4. The number of the fixing blocks 2 can be determined according to the number of the supporting bits 13, and generally, for one supporting bit 13, the number of the fixing blocks on both sides is not less than one, preferably 2 to 3.

The number of the movable blocks 3 is also plural, and the movable blocks 3 are connected in the first chute 11 and the second chute 12 in a manner of being slidable only along the first chute 11 and the second chute 12, specifically, each of the first chute 11 is slidably connected with a plurality of movable blocks 3, and the number of the movable blocks 3 can be determined according to the number of the supporting positions 13, and generally, for one supporting position 13, the number of the movable blocks 3 on both sides is not less than one, preferably 2 to 3.

Meanwhile, the movable block 3 is provided with a connecting part for fixing the workpiece 4, and the connecting part is a threaded hole. Thus, when the workpiece 4 is initially positioned on the support position 13 on the substrate 1, the movable block 3 is moved to align the threaded hole on the movable block with the positioning hole on the workpiece 4, and then the workpiece 4 can be fixed on the substrate 1 by the screw.

It should be noted that, the number of the present application is two or more and includes two.

Referring to fig. 4 and 5, the number of the first sliding grooves 11 is 3, and the number of the second sliding grooves 12 is 2, so that the upper surface of the substrate 1 is divided into 6 supporting positions 13, that is, the substrate 1 can simultaneously clamp 6 workpieces 4. Of course, the number of the supporting positions 13 can be flexibly designed according to the processing requirement, and the embodiment is not limited.

Referring to fig. 6, when CNC processing is utilized, all workpieces 4 on the substrate 1 can be programmed at one time, and then the whole plate is mounted on the workbench 5 of the CNC for processing, compared with the existing single workpiece fixing mode, the number of clamping and gauge checking times can be reduced, the abnormal probability caused by clamping is reduced, and further the processing efficiency is improved, 10 workpieces are clamped once, the clamping and gauge checking time of each workpiece is 10 minutes, and the clamping time of each 10 workpieces can be saved by 90 minutes.

Referring to fig. 1 and 3, the side of the fixed block 2 connected with the workpiece 4 is provided with a magnetic member 21, so that when the workpiece 4 is placed on the supporting position 13, the fixed block 2 can absorb two adjacent sides of the workpiece 4, preventing the workpiece 4 from moving, and facilitating the subsequent fixation of the workpiece 4 by the moving block 3.

Alternatively, the magnetic members 21 are magnets and are embedded in the fixed block 2 at intervals.

Referring to fig. 4, each supporting position 13 of the base plate 1 can clamp the same workpiece 4, or clamp different workpieces 4, so that the positioning holes of the workpieces 4 can be aligned with the first chute 11 and the second chute 12, and the moving blocks 3 in the chutes can be conveniently connected and fixed, and the fixed blocks 2 are connected to the upper surface of the base plate 1 in a manner of adjustable space between the fixed blocks and the first chute 11 or the second chute 12. For example, a transverse kidney-shaped hole may be formed on the left side of the first longitudinal chute 11, and a longitudinal kidney-shaped hole may be formed on the upper side of the second transverse chute 12, so that the fixing block 2 may adjust the distance between the fixing block and the chute according to the position of the positioning hole on the workpiece 4, so as to ensure that the positioning hole of the workpiece 4 can be aligned with the first chute 11 and the second chute 12.

Referring to fig. 6, mounting holes 14 are formed on both left and right sides of the substrate 1, and the size, number and spacing of the mounting holes 14 can be determined according to the specifications of the T-shaped grooves on the workbench 5, so that the substrate 1 can be stably mounted on the workbench 5.

Referring to fig. 1 and 3, the first runner 11 and the second runner 12 have a T-shaped cross section, and the movable block 3 has a T-shaped or rectangular cross section, so that the movable block 3 can slide only along the runner, but cannot be pulled out of the runner upward, thereby being capable of fixing the workpiece 4 on the base plate 1 by a screw.

Optionally, the sections of the first chute 11 and the second chute 12 are dovetail-shaped, and correspondingly, the sections of the movable blocks 3 are dovetail-shaped.

From the above description, it can be seen that the quick clamping tool of the present application is provided with the first chute 11 and the second chute 12 which are crisscrossed with each other on the substrate 1, so that the upper surface of the substrate 1 forms a plurality of supporting positions 13 where the workpieces 4 can be placed, and thus, a plurality of workpieces 4 can be clamped on the substrate 1 at the same time. Simultaneously, fixed block 2 sets up along the spout interval, and when work piece 4 placed on supporting position 13, fixed block 2 can carry out preliminary spacing to the adjacent both sides of work piece 4, and movable block 3 slides and sets up in the spout, removes movable block 3, makes the screw hole on it align with the locating hole on the work piece 4, and the rethread screw can fix work piece 4 on base plate 1. Therefore, when CNC processing is utilized, all workpieces 4 on the substrate 1 can be programmed at one time, and then the whole plate is installed on a workbench 5 of CNC for processing, compared with the existing single workpiece fixing mode, the clamping calibration number can be reduced, the abnormal probability caused by clamping is reduced, and further the processing efficiency is improved, 10 workpieces are clamped once, the clamping time of each workpiece is 10 minutes, and the clamping time of each workpiece can be saved by 90 minutes.
