Description

Technical Field

[0001] This utility model belongs to the field of fixtures and tooling, and specifically relates to a fixture and tooling for clamping bent sleeves. Background Technology

[0002] Bending sleeves are a type of custom-made, specialized workpiece, such as... Figure 6 The curved sleeve has a 90° bend, and both the inner and outer holes at both ends need to be machined. Due to the special structure of the curved sleeve, clamping is difficult. In the existing technology, the chuck and jaws of the lathe are generally used for clamping, but each clamping requires adjustment, which is time-consuming. At the same time, because the step at the end of the curved sleeve is small, it is not easy to quickly position it when using the chuck and jaws for clamping. Each machining operation requires the operator to make adjustments, which is also time-consuming. There is an urgent need for a method to solve this problem. Utility Model Content

[0003] To address the problems existing in the background art, this utility model provides a fixture for clamping bent sleeves.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a clamping fixture for holding a bent sleeve, comprising a bent sleeve, a clamping body, and a jaw; the right end face of the jaw is provided with a groove, and a threaded hole is provided in the groove; the clamping body is a fan-shaped plate, the small arc of the clamping body is adapted to the outer diameter of the bent sleeve, and a countersunk hole is provided in the middle of the right end face of the clamping body; the clamping body is installed in the groove by countersunk screws; the bent sleeve is installed between the clamping bodies.

[0005] The groove is adapted to the clamp body, and the thickness of the clamp body is not less than the depth of the groove.

[0006] The arc angle of the clamping body is less than 120°.

[0007] The clamps are arranged in groups of three, and each group of clamps has the same structure.

[0008] The countersunk hole and the threaded hole are positioned correspondingly.

[0009] The right end face of the countersunk screw is lower than the right end face of the clamping body.

[0010] The beneficial effects of this utility model are as follows: This utility model provides a fixture for clamping bent sleeves. This fixture has a simple structure and is easy to install. It is suitable for clamping small workpieces such as bent sleeves. The clamping end of this fixture is relatively thin, which makes clamping accurate, positioning convenient, and easy to load and unload. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] The following is in conjunction with the appendix Figure 1-6The specific embodiments of this utility model are further described in detail below: A fixture for clamping a bent sleeve includes a bent sleeve 1, a clamping body 2, and a jaw 3. The right end face of the jaw 3 is provided with a groove 5, and a threaded hole 6 is provided in the groove 5. When the clamping body 2 is installed on the groove 5, the right end face of the clamping body 2 is not lower than the right end face of the jaw 3 to prevent tool interference during processing. The clamping body 2 is a fan-shaped plate, and the small arc of the clamping body 2 is adapted to the outer diameter of the bent sleeve 1. The clamping body 2 is a thin plate, and the clamping position is relatively accurate, which is convenient for clamping small workpieces such as bent sleeves 1. However, the thin plate structure of the clamping body 2 has a small clamping force. In order to prevent the workpiece from being thrown out during machine operation due to insufficient clamping force, resulting in an accident, this utility model is not suitable for larger or heavier workpieces. The arc angle of the clamping body 2 is less than 1. The clamping bodies 2 are arranged in groups of three, with each group having the same structure. In actual use, the clamping bodies 2 are mounted on the jaws 3. When the jaws 3 close to clamp the bent sleeve 1, there is a gap between the clamping bodies 2 to prevent the bent sleeve 1 from being unable to be clamped due to being too close. The right end face of the clamping body 2 is provided with a countersunk hole 7, and the clamping body 2 is mounted in the groove 5 by a countersunk screw 4. The countersunk hole 7 corresponds to the position of the threaded hole 6. In this embodiment, each jaw 3 is provided with a threaded hole 6. In actual use, the number of threaded holes 6 can be increased appropriately according to specific requirements. While increasing the number of threaded holes 6, the number and position of the countersunk holes 7 can be adjusted appropriately. The right end face of the countersunk screw 4 is lower than the right end face of the clamping body 2 to prevent tool interference during processing. The bent sleeve 1 is installed between the clamping bodies 2.

[0020] The usage process of this utility model is as follows: First, three identical fan-shaped clamping bodies 2 are made, and countersunk holes 7 are set on the end faces of the clamping bodies 2; then, a groove 5 that matches the clamping body 2 is machined on the right end face of the chuck 3, and a threaded hole 6 is set on the bottom surface of the groove 5; then, the clamping body 2 is installed in the groove 5; when it is necessary to process the bent sleeve 1, first, the chuck 3 is loosened and the end of the bent sleeve 1 to be processed is placed in the clamping body 2, and then the chuck 3 is rotated to clamp the bent sleeve 1 for processing; after processing is completed, the chuck 3 is loosened and the bent sleeve 1 is removed, and the next bent sleeve 1 to be processed is clamped again for processing.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0022] The parts of this utility model not described in detail are existing technologies.
