Description
Technical Field
[0001] This utility model relates to the field of machinery, and more particularly to bench drills, and especially to a bench drill clamp for a casing fork. Background Technology
[0002] The sleeve fork is a common part of automotive drive shafts, which is composed of a tubular part and a fork part. Since the outer walls of the tubular part and the fork part are both cylindrical or arc-shaped, they are difficult to fix during drilling and are prone to slippage, resulting in poor consistency of drilling the center hole.
[0003] In the existing technology, the part is machined by drilling a center hole on a CNC machine tool, then the tailstock clamps the center hole, and the part is turned. This method of machining the center hole affects the machining time and is inefficient. There is an urgent need for a special tooling to work with a bench drill to improve the machining efficiency of subsequent parts. Utility Model Content

This bench drill fixture for casing forks aims to solve the technical problems of poor consistency of machining center holes and low machining efficiency in the prior art.
[0005] This utility model provides a bench drill chuck for a casing fork, including a mounting base and a cylinder. A mounting bracket is provided on the mounting base, and the cylinder is fixedly mounted on the mounting bracket. The cylinder is a gripper cylinder. A switch is provided on the mounting base, one end of which is connected to the cylinder via an air pipe, and the other end of which is connected to an air source. A connecting plate is provided on each of the two gripping arms on both sides of the cylinder. A first clamping block is provided on each of the two connecting plates, and the two first clamping blocks are arranged opposite each other. A first clamping groove is provided on the side wall of any one of the first clamping blocks, and the two first clamping grooves are arranged opposite each other. A second clamping block is also provided on the mounting base, and a second clamping groove is formed on the top of the second clamping block. Both the first and second clamping grooves are V-shaped grooves. The groove of the first clamping groove extends along the vertical direction of the mounting base, and the groove of the second clamping groove extends along the length direction of the mounting base.
[0006] Furthermore, a rib is fixed to one side of the mounting bracket, and the bottom of the rib is fixedly connected to the mounting bracket.
[0007] Furthermore, the mounting base has several mounting holes, and bolts are installed in the mounting holes. The mounting base is connected to the bench drill table through the bolts.

[0015] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.
[0016] like Figures 1 to 3 As shown, this embodiment provides a bench drill fixture for a sleeve fork, used to clamp and process sleeve fork-shaped workpieces 8. A sleeve fork is a common part of an automotive driveshaft, composed of a tubular part and a fork-shaped part.
[0017] The present invention relates to a bench drill clamp for a casing fork, comprising a mounting base 1 and a cylinder 3. A mounting bracket 2 is provided on the mounting base 1, and a rib plate 201 is fixed on one side of the mounting bracket 2. The rib plate 201 is fixedly connected to the mounting base 1 and the mounting bracket 2 to improve the connection firmness.
[0018] A cylinder 3 is installed on the top of one side of the mounting bracket 2. In this embodiment, the cylinder 3 is an HFT32-60S gripper cylinder. This type of cylinder 3 has a gripper arm on each side. The gripper arms on both sides extend and retract simultaneously to achieve a gripping effect.
[0019] A switch 7 is installed at the corner of the mounting base 1. In this embodiment, the switch 7 is an HV-200D hand valve. One end of the switch 7 is connected to the cylinder 3 through an air pipe, and the other end of the switch 7 is connected to an air source, thereby controlling the extension and retraction of the telescopic rods on both sides of the cylinder 3 through the switch 7.
[0020] A connecting plate 4 is fixedly installed on each of the clamping arms on both sides of the cylinder 3. A first clamping block 5 is fixedly installed on each of the two connecting plates 4. The two first clamping blocks 5 are arranged opposite each other. A first clamping groove 501 is provided on the side wall of any one of the first clamping blocks 5. The two first clamping grooves 501 are arranged opposite each other. Both first clamping grooves 501 are V-shaped grooves, and the groove body of the first clamping groove 501 extends along the vertical direction of the mounting base 1. When clamping, the two first clamping grooves 501 clamp the two sides of the tubular part of the sleeve fork respectively. The V-shaped first clamping groove 501 is tangent to the outer diameter of the tubular part to achieve stable clamping.
[0021] The mounting base 1 is also provided with a second clamping block 6. The top of the second clamping block 6 is provided with a second clamping groove 601. The second clamping groove 601 is a V-shaped groove with an upward opening. The groove body of the second clamping groove 601 extends along the length direction of the mounting base 1 and is consistent with the axial direction of the outer diameter of the fork-shaped part of the workpiece. The V-shaped second clamping groove 601 is tangent to the outer diameter of the fork-shaped part, thereby achieving stable clamping.
[0022] The mounting base 1 is also provided with several mounting holes 101. The mounting base 1 is bolted to the bench drill table through the mounting holes 101, thereby fixing the mounting base 1 to the bench drill table.
[0023] How to use this embodiment:
[0024] Place the fork-shaped part of the sleeve fork workpiece 8 downwards into the second clamping groove 601, with the second clamping groove 601 tangent to the outer diameter of the fork-shaped part. Then, rotate the hand valve switch. The hand valve controls the clamping arms on both sides of the cylinder 3 to retract. Through the connecting plate 4 on the clamping arms, the first clamping blocks 5 on both sides move towards each other and close, so that the two first clamping grooves 501 respectively clamp the two sides of the tubular part of the sleeve fork workpiece 8. The first clamping grooves 501 are tangent to the outer diameter of the tubular part, achieving stable clamping. After clamping, drill a hole in the end face of the tubular part away from the fork-shaped part using the operating table drill.
