The arrangement of the clamp base 2 enables the workpieces 4 to be drilled to be clamped in the tool clamp at multiple angles, and the arrangement of the clamping assembly 3 further enables the tool clamp to facilitate clamping and loosening of the workpieces 4, thereby reducing the labor intensity of the workers.

[0035] As Figures 3-4As shown, the clamp base 2 comprises a plate body, a first clamping part and a second clamping part, the plate body, the first clamping part and the second clamping part are integrally formed, a pair of grooves 21 are formed on the first clamping part, the clamping assembly 3 is correspondingly arranged between the pair of grooves 21, the workpiece 4 to be drilled is clamped in the groove 21 and can abut against the clamping assembly 3 and the fixed plate 1; a pair of clamping protrusions 22 are arranged on the second clamping part, the side edges of the clamping protrusion 22 respectively form a pair of first clamping grooves 23 and a pair of second clamping grooves 24 with the plate body, the clamping assembly 3 is correspondingly arranged between the pair of first clamping grooves 23 and the pair of second clamping grooves 24, the workpiece 4 to be drilled can be clamped in the first clamping groove 23 and the second clamping groove 24 and can abut against the clamping assembly 3 and the fixed plate 1. Among them, the clamping protrusion 22 comprises a first side edge and a second side edge, the first side edge and the second side edge are symmetrically arranged about the central axis of the clamping protrusion 22, the first side edge forms the first clamping groove 23 with the plate body, and the second side edge forms the second clamping groove 24 with the plate body.

[0036] In this embodiment, the tool clamp enables the cross section of the workpiece 4 to be clamped on the clamp base 2 parallel to the upper surface of the clamp base 2 through the groove 21 formed on the first clamping part of the clamp base 2. The second clamping part enables the workpiece 4 to be clamped on both sides of the clamping protrusion 22 through the clamping protrusion 22 arranged thereon, the cross section of the workpiece 4 abuts against the inclined side of the clamping protrusion 22, so that the drilling position and angle of the workpiece 4 corresponding to the machine tool drill are changed, and since the first side edge and the second side edge of the clamping protrusion 22 are symmetrically arranged about the central axis of the clamping protrusion 22, when the workpiece 4 is clamped in the first clamping groove 23 and the second clamping groove 24 formed by one clamping protrusion 22, the two workpieces 4 after drilling have corresponding holes, which is convenient for subsequent workers to splice the workpieces 4, and there is no need to compare and splice the inclined drilled workpieces 4 one by one.

[0037] Referring to Figure 1 and Figure 5 , the clamping assembly 3 comprises a pressing block 31, a moving assembly and a pair of clamping pieces 32; the moving assembly is connected with the clamp base 2, the pressing block 31 is arranged at the movable end of the moving assembly to drive the pressing block 31 to reciprocate in the vertical direction, and the pair of clamping pieces 32 are symmetrically arranged on both sides of the pressing block 31 and abut against the side wall of the pressing block 31.

When the workpiece 4 is clamped in the grooves 21 and / or the clamping grooves, the movable nuts 33 are driven to rotate downward, thereby pressing the pressing blocks 31 to gradually move downward. In the process of moving downward, the pressing blocks 31 push the clamping pieces 32 arranged on both sides of the pressing blocks 31, so that the clamping pieces 32 are inclined to the fixed plates 1 on both sides, further pressing the workpiece 4, and increasing the frictional forces between the workpiece 4 and the fixed plates 1, the workpiece 4 and the clamping pieces 32, and the workpiece 4 and the jig base 2, so as to avoid the workpiece 4 from moving in the process of drilling. The center axis of the mounting hole coincides with the center axis of the pressing block 31, so that the pairs of clamping pieces 32 can apply uniform and symmetrical external forces to the workpiece 4 on both sides when the pressing block 31 moves downward, thereby avoiding errors caused by the fact that the clamping forces on the workpiece 4 on both sides of the clamping assembly 3 are inconsistent.

[0039] In a preferred embodiment, the frictional force between the mounting hole and the connecting bolt 34 is greater than the weight of the pressing block 31. The clamping piece 32 is provided with an abutting wall matched with the side wall of the pressing block 31, and the abutting wall is in sliding abutment with the side wall of the pressing block 31. The pairs of clamping pieces 32 are symmetrically arranged on both sides of the pressing block 31. In the embodiment, the frictional force between the mounting hole and the connecting bolt 34 is greater than the weight of the pressing block 31, so that the pressing block 31 can be fixed on the connecting bolt 34 when the movable nut 33 does not move downward, thereby avoiding the inconvenience of storing the tooling fixture in the unused state. The clamping assembly 3 is detachably arranged on the jig base 2 through the connecting bolt 34, thereby further facilitating the disassembly, assembly and maintenance of the tooling fixture.
