Description

Lathe Chuck

technical field

The utility model relates to a lathe chuck, in particular to a lathe chuck which can avoid damage to internal components caused by cutting chips of a workpiece.

Background technique

The traditional lathe chuck mainly includes a body, the body has a shaft hole and three slide grooves arranged radially around the shaft hole, wherein the shaft hole of the body can accommodate a transmission mechanism (such as a pull rod), and each slide of the body The slot can accommodate a fixture. Each clamp can be driven by the transmission mechanism to reciprocate in each chute along the radial direction of the body, and is used to clamp the workpiece to be processed.

However, when the workpiece is cut, a lot of cutting chips will be generated. These cutting chips are easy to flow into the chute of the body with the cutting fluid, and accumulate in the chute of the body and slowly rust, resulting in the gap between each fixture and each chute. The friction force between them will become larger due to the existence of cutting chips, so that when each fixture moves in each chute, it will be affected by the friction force and generate high heat. In addition to reducing the working efficiency of each fixture, it may also lead to the structure of each fixture. damage.

Detailed ways

In order to describe the structure, features and effects of the present utility model in detail, the following preferred embodiments are given below together with the accompanying drawings.

As shown in Figure 1 and Figure 2, the lathe chuck 10 provided by a preferred embodiment of the present invention includes a body 20, a pull rod 30, a dust cover 40, three dust strips 50, and three clamps 60 , Six dustproof plates 70 and six layering strips 80.

The main body 20 is in the shape of a flat cylinder. The center of the body 20 has a shaft hole 22 axially penetrating both sides, and one side of the body 20 has three slide grooves 24, and each slide groove 24 is radially arranged around the shaft hole 22, so that one end of each slide groove 24 is connected to the shaft. The other end of the hole 22 extends to the outer peripheral surface of the body 20 along the radial direction of the body 20 . In addition, the body 20 has a receiving portion 26 on two sides of each slide slot 24 .

The pull rod 30 is installed in the shaft hole 22 of the body 20 and is connected with a machine tool (not shown in the figure), so that the tie rod 30 can move back and forth in the shaft hole 22 of the body 20 relative to the body 20 under the control of the machine tool.

The dust cover 40 is locked on the side of the main body 20 with the chute 24, and covers one end of the shaft hole 22 of the main body 20, so as to prevent the cutting chips of the workpiece from entering the shaft hole 22 of the main body 20 and cause the pull rod 30 or other components to be damaged. damage. The dustproof cover 40 has three notches 42 , each notch 42 communicates with each sliding groove 24 of the main body 20 , and the dustproof cover 40 has a receiving groove 44 below each notch 42 .

The dust-proof strips 50 are wool felts, which are accommodated in the grooves 44 of the dust-proof cover 40 , as shown in FIGS.

Each clamp 60 has a main jaw 62 , a life jaw 64 and a dustproof sheet 66 . The main claw is installed in the chute 24 of the main body 20 and connected with the pull rod 30 , so that the main claw 62 can move back and forth in the chute 24 of the main body 20 under the control of the pull rod 30 for clamping the workpiece to be processed. The raw claw 64 is locked above the main claw 62 and can move along with the main claw 62 . The dust-proof sheet 66 is locked on the front end of the main claw 62 and can move with the main claw 62, and is embedded in the gap 42 of the dust-proof cover 40 and is located above the dust-proof strip 50 (as shown in FIG. 4 ) to assist dust-proof The cover 40 prevents cutting chips of the workpiece from entering the shaft hole 22 of the body 20 .

Each dustproof plate 70 is rubber, and is locked in the accommodation portion 26 of the body 20 in pairs (as shown in FIG. 3 and FIG. 4 ), so as to prevent cutting chips of the workpiece from flowing into each part of the body 20 along with the cutting fluid. In the chute 24.

Each bead 80 is a metal sheet, locked on the top of each dustproof plate 70, and abuts against the peripheral wall of each accommodating portion 26 of the body 20, as shown in Figure 3 and Figure 4, because the cutting chips are extremely high temperature, and prevent The dust plates 70 are made of rubber and are not resistant to high temperature. Therefore, the bead 80 made of metal can prevent the cutting chips from directly contacting the dust plates 70 to prevent the high temperature of the cutting chips from damaging the dust plates 70 .

It can be seen from the above structure that when the workpiece is being cut, a lot of cutting chips will be generated, and some of the cutting chips will flow into the sliding grooves 24 of the main body 20 along with the cutting fluid. Due to the design of the dust-proof plates 70 on both sides of each clamp 60, the cutting chips of the workpiece will be blocked by the dust-proof plates 70 and cannot flow into each chute 24 of the body 20. The dust bar 50 can also prevent cutting chips of the workpiece from flowing into the shaft hole 22 of the body 20 along with the cutting fluid. In addition, some cutting chips will be directly ejected into the accommodating portion 26 of the main body 20, and the design of each metal bead 80 can prevent the high-temperature cutting chips from contacting each dust-proof plate 70 and causing damage to each dust-proof plate 70. damage.

Therefore, the lathe chuck of the utility model utilizes the design of the dustproof plate and the dustproof strip, which can effectively prevent the cutting chips of the workpiece from causing adverse effects or structural damage to the fixture or other internal components of the utility model, achieving the the goal of.

It must be noted that, in the above-mentioned embodiments of the present utility model, three slide grooves 24 and three clamps 60 are disclosed, as well as an equal number of dust-proof strips 50 and equal double-fold dust-proof plates 70 and beading strips 80; In terms of the design of the lathe chuck, it can also be designed as four chutes and the same number of fixtures, so the number of dust-proof strips is equal to the same number of chutes and the number of dust-proof plates and beading is two equal to the number of chutes or fixtures. times the number.
