A multi-station machine tool worktable for a machining center

Abstract

This utility model provides a multi-station machine tool worktable for machining centers, effectively solving the problems of existing dual-station machine tools being unsuitable for gear surface heat treatment, the number of stations severely hindering gear heat treatment efficiency, resulting in low production efficiency and inability to meet production demands. The technical solution includes a rectangular frame with a rotatable turntable on each of the upper and lower side plates. The two turntables are eccentrically arranged and connected by a connecting shaft, the end of which is connected to the turntable via a universal coupling. Multiple circumferentially distributed support platforms are located between the two turntables. Each support platform has two vertical rods hinged to its front side; one vertical rod is fixed to the upper turntable, and the other is fixed to the lower turntable. This utility model has an ingenious structure, achieving non-interference between heat treatment and heat dissipation by adding multiple stations.

Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a multi-station machine tool worktable for machining centers. Background Technology

[0002] When manufacturing gears, the teeth require surface heat treatment after forming to enhance mechanical properties. Current heat treatment methods require individual processing on the machine tool's worktable, severely hindering production efficiency. Patent document CN219725268U proposes a dual-station machine tool, but in actual production, most dual-station machines cannot simultaneously handle loading and unloading, requiring manual operation of each station, limiting its applicability and making it impractical for heat treatment machine tool stations. Patent document CN222308150U utilizes the principle of gears and racks to achieve dual-station operation, but when applied to gear heat treatment, the residual heat of the heat-treated gears makes loading and unloading inconvenient and requires heat dissipation, severely limiting production efficiency. In conclusion, existing dual-station machine tools are unsuitable for gear surface heat treatment; the limited number of stations significantly hinders gear heat treatment efficiency, resulting in low production efficiency and failing to meet production demands.

[0005] The technical solution includes a rectangular frame, with a rotatable turntable on each of the upper and lower side plates of the rectangular frame. The two turntables are eccentrically arranged and connected by a connecting shaft. The end of the connecting shaft is connected to the turntable via a universal coupling. There are multiple circumferentially distributed support platforms between the two turntables. Each support platform has two vertical rods hinged to its front side. One vertical rod is fixed to the upper turntable, and the other vertical rod is fixed to the lower turntable.

[0006] Furthermore, the end of the vertical rod is fixed together with its corresponding turntable via a horizontal rod.

[0007] Furthermore, a motor is connected to one of the turntables, and the motor is fixed to the rectangular frame.

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 5 The present invention includes a rectangular frame 1, with a rotatable turntable on each of the upper and lower side plates of the rectangular frame 1. The two turntables are eccentrically arranged and connected by a connecting shaft 2 between the two turntables. The end of the connecting shaft 2 is connected to the turntable via a universal coupling 3. There are multiple circumferentially distributed support platforms 4 between the two turntables. Each support platform 4 has two vertical rods 5 hinged to its front side. One vertical rod 5 is fixed to the upper turntable, and the other vertical rod 5 is fixed to the lower turntable.

[0018] The end of the vertical rod 5 is fixed together with its corresponding turntable via the horizontal rod 6.

[0019] One of the turntables is connected to a motor 7, which is fixed to the rectangular frame 1.

[0020] A bearing is installed between the vertical rod 5 and the support 4.

[0021] The support platform 4 includes a horizontal flat plate, with a vertical plate fixed to the upper side of the front end of the flat plate, and the vertical rod 5 is hinged to the vertical plate via a bearing.

[0022] It is worth noting that a clamp or fixture can be placed on the flat plate in the support 4 to place or clamp the gear to be processed; the lower end of the rectangular frame 1 is fixed with multiple support rods, and the lower end of the support rods is fixed on the worktable.

[0023] In use, the gear to be processed is placed on the front support 4 and clamped with a fixture. Then, the motor 7 is started to drive one of the turntables to rotate. This turntable, through the connecting shaft 2 and the universal coupling 3 on it, causes the other turntable to rotate as well. In this way, the two turntables rotate synchronously. During the synchronous rotation of the two turntables, multiple support 4s are also moved. The direction of the support 4s remains unchanged during the movement, which facilitates heat processing on the rear side. After heat processing, there is still a period of time before it reaches the front side. During this period of time, the gear can be fully cooled. When the heat-processed gear reaches the front side, its surface temperature has dropped, and it can be easily disassembled and a new part to be processed can be installed.

[0024] This utility model is placed on a workbench, keeping the worker far away from the heat source. This not only protects the worker's safety but also allows for more time to dissipate heat by increasing the number of workstations, thus improving production efficiency.

[0025] This utility model has a clever structure. By adding multiple workstations, it achieves non-interference between heat processing and heat dissipation. The addition of workstations also facilitates the disassembly of the cooled gears, greatly improving production efficiency and meeting production needs.
