Description

Technical Field

[0001] This utility model relates to the field of machining equipment, specifically a lathe center set for the production of automotive turbocharger rotor shafts. Background Technology

[0002] Lathe center sleeves used in the production of automotive turbocharger rotor shafts are key process equipment in the field of precision automotive parts manufacturing, focusing on serving the turning process of this high-requirement component. In modern automotive powertrain systems, the turbocharger rotor shaft, as a core moving component, must maintain micron-level precision and reliability under high-temperature and high-speed conditions, placing stringent standards on machining equipment. As a core auxiliary component in lathe machining, the center sleeve directly impacts the machining quality and production efficiency of the rotor shaft. Its design closely matches the special characteristics of the rotor shaft—the material is typically a high-strength heat-resistant alloy, prone to deformation during machining due to stress or improper clamping; and the shaft is slender with extremely high precision requirements (e.g., radial runout ≤0.005mm), requiring stable rotational support and precise positioning datum. Through targeted optimization, the center sleeve effectively solves the shortcomings of ordinary lathe accessories in terms of support rigidity, thermal stability, and micro-stress control, significantly improving the consistency and yield of rotor shaft machining. As a crucial link in the automotive precision manufacturing industry chain, the application of this top-mounted bushing not only ensures the machining accuracy and service life of the rotor shaft, but also provides underlying process support for the performance reliability of the engine turbocharging system, possessing irreplaceable technical value in the field of high-end automotive parts manufacturing.

[0003] In CNC machine tool processing, precision and efficiency are difficult to balance; friction damage between products and fixtures affects quality; and adjustments for different batches of products are time-consuming and precision is hard to guarantee. Utility Model Content

[0004] The purpose of this utility model is to provide a lathe center set for the production of automotive turbocharger rotor shafts, which solves the problems of difficulty in achieving both precision and efficiency in CNC machine tool processing, quality affected by friction damage between products and fixtures, and time-consuming and precision-difficult to guarantee when changing and adjusting products from different batches.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lathe center set for the production of automotive turbocharger rotor shafts, comprising a mounting plate, a first kit slidably connected inside the mounting plate, a second kit disposed inside the first kit, a third kit disposed inside the second kit, a threaded rod slidably connected inside the first kit, the threaded rod being threadedly connected to the mounting plate, a knob fixedly connected to the upper end of the threaded rod, the knob contacting the first kit, a limiting sleeve slidably connected inside the first kit, the limiting sleeve being slidably connected to the knob, and a limiting mechanism disposed on the limiting sleeve.

[0006] Preferably, the lower end of the limiting sleeve is fixedly connected to a limiting block, and the limiting block is slidably connected to the knob. Through the design of the limiting block, the knob can be limited.

[0007] Preferably, the first kit has a fixed internal connection of a positioning block, which is slidably connected to the limiting sleeve. The positioning block is designed to position the limiting sleeve.

[0008] Preferably, the limiting mechanism includes a push plate, a locking block is fixedly connected to the side of the push plate near the first kit, and a sliding rod is fixedly connected to the side of the push plate away from the locking block. The sliding rod is slidably connected to the limiting sleeve, and a spring is provided inside the limiting sleeve. Through the design of the limiting mechanism, the limiting sleeve can remain stable when limiting the knob.

[0009] Preferably, the locking block is slidably connected to the limiting sleeve, and the locking block is slidably connected to the kit. Through the design of the locking block, the limiting sleeve can be limited.

[0010] Preferably, a limiting ring is fixedly connected inside the limiting sleeve, and the limiting ring is slidably connected to the slide rod. Through the design of the limiting ring, the slide rod can be limited.

[0011] Preferably, one end of the spring contacts the slide rod, and the other end of the spring contacts the limiting sleeve. Through the design of the spring, the locking block is driven to limit the limiting sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model constructs a key tooling system for CNC machine tool processing by setting up three kits: Kit 1 strengthens the fixation between the kit and the machine tool, ensuring processing stability; Kit 2 enables rapid batch changeover, ensuring changeover accuracy; Kit 3 reduces friction between the product and the fixture, minimizing damage. This design effectively solves the problems of difficulty in balancing precision and efficiency, fixture friction affecting quality, and time-consuming batch changeovers with uncertain accuracy, thereby improving processing reliability and production efficiency.

[0013] 2. This utility model uses a limiting sleeve to limit the threaded rod, ensuring a stable installation of the first kit and the mounting plate. It also adds a push plate, a locking block, and a spring component. The spring force drives the locking block on the push plate to slide into the first kit, creating a secondary limit on the limiting sleeve. This double-locking design effectively prevents the limiting sleeve from loosening or shifting, significantly improving the stability of the component connection and the reliability of the structure, ensuring accurate positioning and reliable force application during processing.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 A lathe center set for the production of automotive turbocharger rotor shafts includes a mounting plate 1, a kit 2 that is slidably connected inside the mounting plate 1, a kit 21 that is disposed inside the kit 21, a kit 3 22 that is disposed inside the kit 21, a threaded rod 3 that is slidably connected inside the kit 2, the threaded rod 3 being threadedly connected to the mounting plate 1, a knob 31 that is fixedly connected to the upper end of the threaded rod 3, the knob 31 being in contact with the kit 2, and a limit sleeve 4 that is slidably connected inside the kit 2.

[0018] Please see Figure 2-4 The limiting sleeve 4 is slidably connected to the knob 31. The lower end of the limiting sleeve 4 is fixedly connected to the limiting block 41. The limiting block 41 is slidably connected to the knob 31. Through the design of the limiting block 41, the knob 31 can be limited. The internal part of the kit 1 2 is fixedly connected to the positioning block 42. The positioning block 42 is slidably connected to the limiting sleeve 4. Through the design of the positioning block 42, the limiting sleeve 4 can be positioned. The limiting sleeve 4 is provided with a limiting mechanism 5.

[0019] Please see Figure 2-4The limiting mechanism 5 includes a push plate 51. A locking block 52 is fixedly connected to the side of the push plate 51 near the first kit 2. The locking block 52 is slidably connected to the limiting sleeve 4. The locking block 52 is designed to limit the limiting sleeve 4. A sliding rod 53 is fixedly connected to the side of the push plate 51 away from the locking block 52. The sliding rod 53 is slidably connected to the limiting sleeve 4. A limiting ring 54 is fixedly connected inside the limiting sleeve 4. The limiting ring 54 is slidably connected to the sliding rod 53. The limiting ring 54 is designed to limit the sliding rod 53. A spring 55 is provided inside the limiting sleeve 4. One end of the spring 55 contacts the sliding rod 53, and the other end of the spring 55 contacts the limiting sleeve 4. The spring 55 drives the locking block 52 to limit the limiting sleeve 4. The limiting mechanism 5 is designed to keep the limiting sleeve 4 stable when limiting the knob 31.

[0020] The specific implementation process of this utility model is as follows: In use, the three components 22, the two components 21, and the one component 2 are assembled. Then, the one component 2 is installed on the mounting plate 1 by the threaded rod 3. By moving the two push plates 51 towards each other, the push plates 51 drive the slide rod 53 to squeeze the spring 55, causing the push plates 51 to drive the locking block 52 to slide into the limiting sleeve 4. Then, the limiting sleeve 4 is slidably connected to the knob 31, and the limiting sleeve 4 is slidably connected to the positioning block 42, so that it positions the limiting sleeve 4. The limiting block 41 on the limiting sleeve 4 slides into the knob 31, which can limit the knob 31, thereby limiting the threaded rod 3, so that the one component 2 can remain stable after installation. Then, by releasing the push plate 51, the spring force of the spring 55 can drive the slide rod 53 to move, and the slide rod 53 can drive the push plate 51 to move, which can then drive the locking block 52 to reset, and the locking block 52 can slide into the kit 1 2, which can then limit the limiting sleeve 4, so that the limiting sleeve 4 remains stable when limiting the knob 31, and thus the kit 1 2 remains stable after installation. Kit 1 (2) reinforces the fixation between the kit and the machine tool to ensure processing stability; Kit 2 (21) enables rapid batch changeover to ensure production changeover accuracy; Kit 3 (22) reduces friction between the product and the fixture to minimize damage.
