Description

Technical Field

[0001] This utility model relates to the field of positioning tooling and fixture technology, and more specifically, to a machining positioning fixture for a card holder. Background Technology

[0002] like Figure 1 The fixture shown includes an upper groove and a lower support. The support has a through hole along its length. To machine the through hole, the support needs to be facing upwards. The groove is fixed by clamping it in a bench vise before drilling. The side plates of the groove are prone to deformation under stress, making it difficult to machine, position, and clamp the fixture. Therefore, there is an urgent need for a fixture that can position the fixture. Utility Model Content

The piston rod of the first pressing cylinder is provided with a first pressing rod, which extends above one side of the support block. The second pressing cylinder is provided with a second pressing rod, which extends above the other side of the support block.

[0005] Furthermore, the support block is in the shape of an inverted "m", and several pads are respectively provided on the upper surface of the support block.

[0006] Furthermore, a first top block is further provided on the first positioning block, and the first top block extends toward one side of the support block.

[0007] Furthermore, a second top block is further provided on the second positioning block, and the second top block faces the support block.

[0008] Furthermore, the support block, the first positioning block, and the second positioning block are respectively locked to the base plate by bolts.

[0009] Furthermore, the base plate is I-shaped, and fixing holes are opened at both ends of the base plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model discloses a simple and ingeniously designed machining and positioning fixture for a card holder. It includes a base plate with two first positioning blocks and two second positioning blocks mounted on it. A support block is positioned between the first and second positioning blocks. A first clamping cylinder is positioned between the two first positioning blocks, and a second clamping cylinder is positioned between the two second positioning blocks. The piston rod of the first clamping cylinder has a first pressure rod extending above one side of the support block. The second clamping cylinder has a second pressure rod extending above the other side of the support block. In use, the slot of the card holder is inverted onto the support block, with the side plates of the slot positioned between the first and support blocks, and between the second and support blocks. The first and second clamping cylinders are controlled to push the first and second pressure rods respectively, pressing the sides of the slot onto the support block to achieve positioning and clamping of the card holder. The inverted position of the slot onto the support block avoids the need for clamping with a bench vise, thus preventing deformation of the card holder. Attached Figure Description

[0024] Example

[0025] Reference Figure 2-5As shown, this utility model discloses a processing and positioning fixture for a card holder 20, including a base plate 10, on which two first positioning blocks 101 and two second positioning blocks 102 are installed. A support block 103 is provided between the first positioning blocks 101 and the second positioning blocks 102. A first pressing cylinder 104 is provided between the two first positioning blocks 101, and a second pressing cylinder 105 is provided between the two second positioning blocks 102. The piston rod of the first pressing cylinder 104 is provided with a first pressing rod 1041, which extends to the upper side of one side of the support block 103. The second pressing cylinder 105 is provided with a second pressing rod 1051, which extends to the upper side of the other side of the support block 103. Specifically, in use, the slot 201 of the card holder 20 is inverted onto the support block 103. The two side plates of the slot 201 are respectively placed between the first positioning block 101 and the support block 103, and between the second positioning block 102 and the support block 103. Further control the first pressing cylinder 104 to drive the first pressing rod 1041 to press one side of the slot 201 onto the support block 103, and control the second pressing cylinder 105 to drive the second pressing rod 1051 to press the other side of the slot 201 onto the support block 103. This achieves the effect of pressing both sides of the slot 201 onto the support block 103, avoiding the deformation caused by clamping the two side plates of the slot 201 with a bench vise. In addition, the support block 103 can restrict the movement of the card holder 20, resulting in a good positioning effect.

[0026] Reference Figure 2-5 As shown, the support block 103 is in the shape of an inverted M. Several pads 1031 are respectively provided on the upper end surface of the support block 103. The pads 1031 support the inside of the column groove 201 to avoid wear caused by direct contact between the groove 201 and the support block 103. A first top block 1011 is further provided on the first positioning block 101. The first top block 1011 extends toward the support block 103 and is bolted to the first positioning block 101. The first top block 1011 extends toward the support block 103 to hold the side plate of the groove 201 against the support plate. A second top block 1021 is further provided on the second positioning block 102. The second top block 1021 faces the support block 103 and is bolted to the second positioning block 102. The second top block 1021 holds the side plate of the groove 201 against the support block 103. The first top block 1011 and the second top block 1021 hold the two side plates of the groove 201 against the two sides of the support block 103, respectively, to further clamp and fix the groove 201 and prevent vibration during drilling.

[0027] In this embodiment, the support block 103, the first positioning block 101, and the second positioning block 102 are respectively locked to the base plate 10 by bolts, which facilitates processing and overall assembly.

[0028] In addition, the base plate 10 is I-shaped, and there are fixing holes at both ends of the base plate 10 to reduce the weight of the base plate 10. The base plate 10 is installed and fixed on the machine base through the fixing holes to increase the overall stability.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
