Abstract
The utility model belongs to the technical field of machining, concretely relates to flexible jack catch. In order to solve the problem that the locating turning brake disc edge is pressed from both sides and collapses in dividing, a flexible jack catch the lower part transversely sets up a counter bore (6) in each clamping area of jack catch body (2), is equipped with in counter bore (6) in proper order and fixes a position nail (3), and spring (4) and screw thread are stifled (5), are equipped with the step on fixing a position nail (3), and it is spacing through the step after fixing a position nail (3) microcephaly end passes counter bore (6), and the other end supports with spring (4), and spring (4) are stifled (5) spacing with the screw thread at the back, and the part that fixing a position nail (3) stretched out jack catch body (2) clamping area is conical. The centering positioning and clamping of the workpiece can be realized, and the workpiece cannot be damaged.
Description
Technical Field
The utility model belongs to the technical field of machining, especially, relate to a jack catch that lathe chuck was used.
Background
The jaw of the lathe chuck is used for clamping a workpiece and assisting in positioning, the jaw in a common shape can clamp the excircle of the workpiece or tension the inner hole to turn a part, and the automatic positioning requirement is higher for a numerical control and automatic lathe, so that a special jaw is often required to be designed. The disc brake disc is divided into a solid disc and an air duct disc, and an automobile needs to achieve the purpose of heat dissipation through air convection at the air duct during running. In actual production, when an air duct brake disc is machined, in the prior art, a plurality of clamping jaws are clamped on the air duct brake disc in a circular array mode, so that the plurality of clamping jaws act on the air duct brake disc, and the centering and positioning effect is finally achieved. But the general claw has the problem that the edge is clamped and cracked when the turning brake disc is positioned in the center.
Disclosure of Invention
In order to overcome the problem that the location turning brake disc edge was pressed from both sides and collapses in dividing, the utility model provides a location in can realizing the brake disc divides to centre gripping turning can not cause the flexible jack catch of work piece damage.
The utility model aims at realizing through the following technical scheme: a flexible clamping jaw comprises a clamping jaw body 2, wherein a cylindrical counter bore 6 is transversely arranged at the lower middle part of each clamping area of the clamping jaw body 2, a positioning nail 3, a spring 4 and a thread plug 5 are sequentially arranged in the counter bore 6 from the side of a clamped workpiece, a step corresponding to the cylindrical counter bore 6 is arranged on the positioning nail 3, the small end of the positioning nail 3 passes through the counter bore 6 and then is limited by the step, the other end of the positioning nail is supported by the spring 4, the rear part of the spring 4 is limited by the thread plug 5, the part of the positioning nail 3 extending out of the clamping area of the clamping jaw body 2 is conical, and the conical tip aims at the center; the compressible length of the spring 4 is larger than the distance from the inner end surface of the clamping area of the jaw body 2 to the workpiece.
Furthermore, the diameter of the conical big end of the positioning nail 3 is larger than the ventilation gap of the brake disc.
The working principle is as follows: when the claw body 2 is clamped inwards, the conical positioning nail 3 contacts the brake disc 1 firstly, the conical small end of the conical positioning nail is inserted into the ventilation gap of the brake disc, the centering positioning is realized, when the claw body 2 continues to be clamped inwards, the spring 4 supporting the positioning nail 3 is compressed until the clamping area of the claw body 2 clamps the brake disc 1, the clamping stress surface is flat, and the workpiece cannot be damaged.
The utility model discloses when the jack catch body is inwards pressed from both sides tightly, the tip end of conical location nail contacts the brake disc earlier, and the compressible length of spring is greater than the distance of terminal surface to the work piece in the jack catch body clamping area, and the location nail is compressed into the cylinder counter bore when guaranteeing to press from both sides tightly, lets jack catch body clamping area press from both sides tightly, and at this moment the stress surface is just flat, can realize fixing a position and pressing from both sides tightly in the branch of brake disc to can not cause the damage to the brake disc, simple structure simple to operate.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is the schematic view of the structure of the brake disc clamping process of the present invention.
In the figure, 1, a brake disc, 2, a jaw body, 3, a positioning nail, 4, a spring, 5, a thread plug and 6, a counter bore.
Detailed Description
As shown in fig. 1 and 2, including the jack catch body 2 the lower part transversely sets up a cylinder counter bore 6 in each clamping area of jack catch body 2, is equipped with location nail 3 in the counter bore 6 in proper order from the centre gripping work piece side, and spring 4 and screw thread block 5, be equipped with the step that corresponds with cylinder counter bore 6 on the location nail 3, it is spacing through the step after the counter bore 6 is passed to the little head end of location nail 3, and the other end supports with spring 4, and spring 4 is stifled 5 spacing with the screw thread at the back, and the part that location nail 3 stretches out 2 clamping areas of jack catch body is conical, and the awl point is to 6 central points on the counter bore.
The diameter of the conical big end of the positioning nail 3 is larger than the ventilation gap of the brake disc.
The compressible length of the spring 4 is larger than the distance from the inner end surface of the clamping area of the jaw body 2 to the workpiece.
When the claw body 2 is clamped inwards, the conical positioning nail 3 contacts the brake disc 1 firstly, the conical small end of the conical positioning nail is inserted into the ventilation gap of the brake disc, the centering positioning is realized, when the claw body 2 continues to be clamped inwards, the spring 4 supporting the positioning nail 3 is compressed until the clamping area of the claw body 2 clamps the brake disc 1, the clamping stress surface is flat, and the workpiece cannot be damaged.
