Description

Technical Field

[0001] This utility model relates to the field of fixed tooling technology, specifically a fixed tooling for machining rotating shells. Background Technology

[0002] A housing is a common type of mechanical part. Housings are generally manufactured by casting to complete the outer shape and then machining to fix the outer surface of the housing.

[0003] According to a public notice (No. CN114310379B) of a fixed fixture for shell processing, the above application provides a pressing part at the upper end of the movable jaw, and then drives the movable jaw to switch positions through a driving component, pressing the pressing part onto the upper end of the shell to complete the fixation of the shell on the fixture. This fixes the shell without damaging the hole wall of the shell or the shell structure itself. Furthermore, the position switching of the sliding jaw is achieved by using an outer sliding column, an inner sliding column, a spring, a first rotating shaft, and a second rotating shaft.

[0004] However, in actual use, when other parts are installed on the outer surface of the rotating housing, the rotating housing will be subjected to pressure, causing it to rotate and making it impossible to stably mount the tooling parts on the outer surface of the rotating housing. In view of this, we propose a fixed tooling for machining the rotating housing. Utility Model Content

[0005] The purpose of this invention is to provide a fixed fixture for machining a rotating housing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixed fixture for machining a rotating housing, comprising a fixture table, an mounting groove formed on the upper surface of the fixture table, a motor fixedly connected to the bottom of the inner wall of the mounting groove, a rotating disk fixedly connected to the output end of the motor, a three-jaw chuck fixedly connected to the upper surface of the rotating disk, and a limit component provided on the upper surface of the fixture table, the limit component comprising:

[0007] The mounting component is fixedly connected to the upper surface of the tooling table. A threaded rod is rotatably connected to the inner wall side of the mounting component. A limit block is threadedly connected to the outer surface of the threaded rod. A retaining strip is fixedly connected to the side of the limit block.

[0008] A limiting groove is formed on the outer surface of the rotating disk.

[0009] Preferably, the center of the limiting groove corresponds to the center of the outer surface of the rotating disk, and an arc-shaped groove is provided on the inner wall side of the limiting groove, which makes the limiting groove and the limiting block more stable in limiting the rotating disk.

[0010] Preferably, the limiting block is L-shaped, and the side of the horizontal portion of the limiting block is arc-shaped. The position of the horizontal portion of the limiting block corresponds to the position of the limiting groove, so that the horizontal portion of the limiting block can be well inserted into the limiting groove.

[0011] Preferably, the locking strip is composed of a convex strip with a fixedly connected oblique member on its outer surface, and the locking strip is evenly distributed in a circumferential array on the side of the horizontal part of the limiting block, which increases the friction between the limiting block and the limiting groove.

[0012] Preferably, the bottom of the rotating disk is provided with an auxiliary component, the auxiliary component includes a movable part, the movable part is fixedly connected to the bottom of the rotating disk, the outer surface of the movable part is provided with ball bearings, and the upper surface of the tooling table is provided with a movable groove.

[0013] Preferably, the position of the movable component corresponds to the position of the movable groove, and the size of the movable component is adapted to the size of the movable groove.

[0014] Preferably, the balls are evenly distributed in a circumferential array on the outer surface of the moving part, and the outer surface of the balls is in contact with the inner wall of the moving groove.

[0015] Compared with the prior art, this utility model provides a fixed tooling for machining rotating housings, which has the following advantages:

[0016] 1. This fixture for machining a rotary housing is designed to ensure more stable tooling on the outer surface of the rotary housing. The rotary housing is fixed in place by a three-jaw chuck. When tooling on the outer surface of the rotary housing, rotating the threaded rod moves the horizontal portion of the L-shaped limiting block towards the limiting groove, allowing it to engage with the groove. The limiting block has a retaining strip on its side, and the inner wall of the limiting groove has an arc-shaped groove. This increases the friction between the limiting block and the limiting groove after the arc-shaped surface of the horizontal portion of the limiting block contacts the arc-shaped surface of the inner wall of the limiting groove, thus making the rotary housing more stable during tooling.

[0017] 2. This fixture for machining the rotary housing aims to make the rotary housing more stable during rotation. When the motor is started, the rotating disk rotates, and during the rotation of the rotating disk, the moving parts rotate inside the moving groove. At the same time, the balls on the outer surface of the moving parts will contact the inner wall of the moving groove, which makes the rotating disk more stable during rotation.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a fixed fixture for machining a rotating shell, including a fixture table 1, an installation groove 2 on the upper surface of the fixture table 1, a motor 3 fixedly connected to the bottom of the inner wall of the installation groove 2, a rotating disk 4 fixedly connected to the output end of the motor 3, a three-jaw chuck 5 fixedly connected to the upper surface of the rotating disk 4, and a limit component 6 provided on the upper surface of the fixture table 1, the limit component 6 including an installation part 602, a threaded rod 603, a limit block 604, a clamping strip 605, and a limit groove 601.

[0025] In this embodiment of the present invention, the mounting component 602 is fixedly connected to the upper surface of the tooling table 1. A threaded rod 603 is rotatably connected to the inner wall side of the mounting component 602. A limiting block 604 is threadedly connected to the outer surface of the threaded rod 603. The limiting block 604 is L-shaped, and the horizontal part of the limiting block 604 is arc-shaped. The position of the horizontal part of the limiting block 604 corresponds to the position of the limiting groove 601, which allows the horizontal part of the limiting block 604 to fit well into the limiting groove 601. A threaded rod 603 is fixedly connected to the side of the limiting block 604. The locking strip 605 is composed of a convex strip fixedly connected to a slanted piece on its outer surface. The locking strip 605 is evenly distributed in a circumferential array on the side of the horizontal and vertical part of the limiting block 604. This increases the friction between the limiting block 604 and the limiting groove 601. The limiting groove 601 is opened on the outer surface of the rotating disk 4, and the center of the limiting groove 601 corresponds to the center of the outer surface of the rotating disk 4. An arc-shaped groove is opened on the inner wall side of the limiting groove 601, which makes the limiting of the rotating disk 4 more stable after the limiting groove 601 contacts the limiting block 604.

[0026] Meanwhile, an auxiliary component 7 is provided at the bottom of the rotating disk 4. The auxiliary component 7 includes a movable part 701, which is fixedly connected to the bottom of the rotating disk 4. The position of the movable part 701 corresponds to the position of the movable groove 703, and the size of the movable part 701 is adapted to the size of the movable groove 703. The outer surface of the movable part 701 is provided with balls 702, which are evenly distributed in a circumferential array on the outer surface of the movable part 701. The outer surface of the balls 702 is in contact with the inner wall of the movable groove 703. The upper surface of the tooling table 1 is provided with a movable groove 703. This allows the rotating disk 4 to rotate when the motor 3 is started, and the movable part 701 will rotate inside the movable groove 703 during the rotation of the rotating disk 4. At the same time, the balls 702 on the outer surface of the movable part 701 will contact the inner wall of the movable groove 703, which makes the rotating disk 4 more stable when rotating.

[0027] In this invention, during use, the rotating housing is fixed in place by a three-jaw chuck 5. When tooling is performed on the outer surface of the rotating housing, the threaded rod 603 is rotated to move the horizontal part of the L-shaped limiting block 604 towards the limiting groove 601, and the horizontal part of the L-shaped limiting block 604 is engaged in the limiting groove 601. The limiting block 604 has a retaining strip 605 on its side, and the inner wall of the limiting groove 601 has an arc-shaped groove. This increases the friction between the limiting block 604 and the limiting groove 601 after the arc-shaped surface of the horizontal part of the limiting block 604 contacts the arc-shaped surface of the inner wall of the limiting groove 601, thereby making the rotating housing more stable during tooling.

[0028] Furthermore, when the motor 3 is started, the rotating disk 4 is rotated. During the rotation of the rotating disk 4, the movable part 701 rotates inside the movable groove 703. At the same time, the ball bearings 702 on the outer surface of the movable part 701 will contact the inner wall of the movable groove 703, which makes the rotating disk 4 more stable when it rotates.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
