AI Technical Summary
Traditional clamps are difficult to control when holding thin-walled tubes, especially for tubes with a wall thickness of less than 1 mm, which can easily cause the tube wall to dent.
A tooling fixture including a mounting body, a clamping part, a buffer part, and an adjustment mechanism is designed. The buffering state of the buffer part is controlled by the adjustment mechanism to realize the elastic movement of the clamping part. The elastic restoring force of the buffer part and the spring is used to achieve elastic clamping of the thin-walled tube.
It effectively reduces the deformation of thin-walled tubes during clamping and solves the problem of difficult clamping force control when clamping thin-walled tubes with traditional clamps, especially for tubes with a wall thickness of less than 1mm, thus avoiding tube wall indentation.

Abstract
Claims
1. A tooling fixture for stamping hardware, comprising: The device includes a mounting body and a thin-walled tube inserted inside the mounting body. Clamping parts are provided on opposite sides inside the mounting body, and the thin-walled tube is located between the clamping parts. A buffer part is provided between the clamping parts to buffer the clamping force of the clamping parts, and the buffer part is located at the bottom of the mounting body. An adjustment mechanism is provided on the mounting body to control the buffering state of the buffer part. The adjustment mechanism contacts the clamping parts and controls the buffering state of the buffer part, thereby driving the clamping parts to move elastically within the mounting body, thereby achieving elastic clamping of the thin-walled tube.
2. A tooling jig for stamping hardware according to claim 1, wherein, The clamping part includes a sleeve that is movably inserted into the mounting body on one side, and a clamping element that contacts the thin-walled tube is movably inserted inside the sleeve.
3. A tooling fixture for stamping hardware according to claim 2, wherein, A cap is inserted into the other side of the sleeve, and a first spring is provided between the cap and the clamping member to compensate for the clamping force of the thin-walled tube. The two ends of the first spring are welded to the cap and the end face of the clamping member, respectively.
4. A tooling jig for stamping hardware according to claim 2, wherein, A first limiting block is formed on one side of the sleeve near the clamping member, and the first limiting block is distributed around the sleeve itself. A second limiting block is formed around the clamping member to engage with the first limiting block.
5. A tooling fixture for stamping hardware parts according to claim 1, characterized in that, The adjustment mechanism includes a screw threaded onto the side of the mounting body, and the nut end near the threaded surface is tapered. L-shaped push rods are provided on opposite sides of the screw, and the L-shaped push rods move inside the mounting body. One end of the L-shaped push rod is formed with an inclined surface that engages with the tapered wedge.
6. A tooling jig for the stamping of hardware according to claim 5, wherein, The L-shaped push rod has a first limiting groove inside, and the first limiting groove passes through the L-shaped push rod. The mounting body has a second limiting groove inside, which communicates with the first limiting groove. The second limiting groove is aligned with the first limiting groove. A first positioning pin is inserted into the second limiting groove, and one end of the first positioning pin is located in the first limiting groove.
7. A tooling jig for the stamping of hardware according to claim 6, wherein, A silicone sleeve is fitted on one end of the first positioning pin, and the silicone sleeve is located inside both the first limiting groove and the second limiting groove.
8. A tooling fixture for stamping hardware according to claim 5, wherein, A balance block is fitted around the L-shaped push rod, and a second positioning pin is provided between the balance block and the L-shaped push rod. The second positioning pin passes through both the L-shaped push rod and the balance block.
