As shown in fig. 1 to 5, the embodiment of the present invention provides a tooling fixture for clamping a part 10, which includes a base 20, a plurality of mounting grooves 21 are provided on the base 20 for accommodating the part 10, a first inner side wall 211 and a second inner side wall 212 opposite to the first inner side wall 211 are formed in the mounting groove 21, a pressing block 30 and a wedge block 40 are provided in each mounting groove 21 (for more clearly displaying, in fig. 1, only relevant structures in one mounting groove 21 are displayed), when the part 10 is clamped in the mounting groove 21, the part 10, the pressing block 30 and the wedge block 40 are sequentially disposed between the first inner side wall 211 and the second inner side wall 212, and the wedge block 40 is disposed between the pressing block 30 and the second inner side wall 212 of the mounting groove 21. When the wedge block 40 extends between the pressing block 30 and the second inner side wall 212 of the mounting groove 21, the wedge block 40 pushes the pressing block 30 to press the part 10 between the first inner side wall 211 of the mounting groove 21 and the pressing block 30.

In this embodiment, through the arrangement of the wedge-shaped block 40, when the part 10 is clamped, firstly, the part 10 is placed on the side of the pressing block 30 away from the wedge-shaped block 40, then, the wedge-shaped block 40 extends between the pressing block 30 and the second inner side wall 212 of the mounting groove 21, and when the wedge-shaped block extends between the pressing block 30 and the second inner side wall 212, the wedge-shaped block 40 pushes the part 10 to move through the pressing block 30, so that the part 10 is clamped between the first inner side wall 211 of the mounting groove 21 and the pressing block 30; due to the arrangement of the pressing block 30, when the wedge-shaped block 40 pushes the part 10 to move, the pressing block 30 does not move relative to the part 10 in the height direction (i.e., the up-down direction in fig. 4) of the part 10, but only pushes the part 10 to move towards the first inner side wall 211 of the mounting groove 21, which can prevent the part 10 from being scratched due to the displacement between the part 10 and the pressing block 30. Therefore, the tool clamp can quickly assemble parts in batches, and machining efficiency is improved.

A first inclined surface 41 is formed on at least one side surface of the wedge block 40, and a second inclined surface 31 corresponding to the first inclined surface 41 is formed on at least one of the second inner side wall 212 of the installation groove 21 and the pressing block 30.

By forming the first inclined surface 41 on at least one side surface of the wedge block 40, the second inclined surface 31 matched with the first inclined surface 41 is formed on at least one of the second inner side wall 212 of the installation groove 21 and the pressing block 30. When the component 10 is clamped, the first inclined surface 41 and the second inclined surface 31 interact with each other, so that the component 10 is clamped between the first inner side wall 211 of the mounting groove 21 and the pressing block 30.

More specifically, as shown in fig. 4, in the present embodiment, the first inclined surface 41 is formed on the side of the wedge block 40 facing the pressing block 30, and correspondingly, the second inclined surface 31 is formed on the side of the pressing block 30 facing the wedge block 40. It is understood that, in another embodiment, the first inclined surface 41 may be formed on a side surface of the wedge block 40 away from the pressing block 30, and correspondingly, the second inclined surface 31 is formed on the second inner side wall 212 of the mounting groove 21.

In another embodiment, the first inclined surface 41 may be disposed on two opposite sides of the wedge block 40, and accordingly, the second inclined surface 31 is disposed on a side of the pressing block 30 facing the wedge block 40 and the second inner side wall 212 of the mounting groove 21.

In the present embodiment, as shown in fig. 4, the wedge block 40 has a right trapezoid shape in a cross section perpendicular to the first inclined surface 41, and the thickness of the wedge block 40 in the direction from the top of the wedge block 40 to the bottom of the wedge block 40 is gradually reduced in the cross section from the first inner side wall 211 to the second inner side wall 212.

Further, in this embodiment, the tooling clamp further includes a locking structure, the locking structure includes a locking bolt 51, a first mounting hole 52 is formed on the wedge block 40, a second mounting hole 53 is formed on the bottom surface of the mounting groove 21, and the locking bolt 51 passes through the first mounting hole 52 and extends into the second mounting hole 53, so that the wedge block 40 is fixed in the mounting groove 21.

In order to clamp a plurality of parts 10 with different thicknesses, in this embodiment, the pressing blocks 30 are divided into different models, the pressing blocks 30 with different models have different thicknesses, and when clamping the parts 10 with different thicknesses, the pressing blocks 30 with corresponding thicknesses can be selected, so that when the wedge-shaped block 40 is fixed in the mounting groove 21 by the locking structure, the pressing blocks 30 press the parts 10 against the first inner side wall 211 of the mounting groove 21.

Further, the height of the wedge block 40 is smaller than the depth of the installation groove 21, that is, as shown in fig. 4, after the part 10 is clamped, a certain gap is left between the bottom of the wedge block 40 and the bottom of the installation groove 21, which can ensure the part 10 to be pressed by the pressing block 30, and prevent the situation that the pressing force is not provided to the pressing block 30 any more because the wedge block 40 moves to the bottom of the installation groove 21.

Further, in order to prevent the mounting groove 21 from damaging the component 10, an arc-shaped chamfer 213 is formed between the first inner side wall 211 and the inner side wall of the adjacent mounting groove 21.

In the present embodiment, an arc-shaped chamfer 213 is formed on one end of the first inner sidewall 211, and a receiving hole 214 is formed between the other end of the first inner sidewall 211 and the adjacent mounting groove 21. When the width of the component 10, i.e., the length of the component 10 in the up-down direction in fig. 3, is slightly greater than the width of the first inner sidewall 211, the arc-shaped chamfer can guide the component 10 to move so that the corner on the other side of the component 10 is received in the receiving hole 214. The above-described structure can accommodate errors in the width direction of the part 10.

In summary, in the present invention, through the arrangement of the wedge-shaped block 40, when the part 10 is clamped, firstly, the part 10 is placed on one side of the pressing block 30 away from the wedge-shaped block 40, and then the wedge-shaped block 40 extends between the pressing block 30 and the second inner side wall 212 of the mounting groove 21, when the wedge-shaped block extends between the pressing block 30 and the second inner side wall 212, the wedge-shaped block 40 will push the part 10 to move through the pressing block 30, so that the part 10 is clamped between the first inner side wall 211 of the mounting groove 21 and the pressing block 30; due to the arrangement of the pressing block 30, when the wedge-shaped block 40 pushes the part 10 to move, the pressing block 30 does not move relative to the part 10 in the height direction (i.e., the up-down direction in fig. 4) of the part 10, but only pushes the part 10 to move towards the first inner side wall 211 of the mounting groove 21, which can prevent the part 10 from being scratched due to the displacement between the part 10 and the pressing block 30. Therefore, the tool clamp can quickly assemble parts in batches, and machining efficiency is improved.
