Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical processing and manufacturing equipment, specifically a CNC external sanding machine for the inner pot of a rice cooker. Background Technology
[0002] The inner pot of a rice cooker is one of its core components, and its polishing quality directly affects the product's quality grade. Traditionally, rice cooker inner pots are polished manually. However, the quality of manual polishing is affected by various external factors such as the worker's polishing skills, physical strength, environment, and mood, leading to inconsistent product quality. Currently, the polishing process requires highly skilled workers, necessitating extensive training to achieve the necessary techniques to produce qualified products. Therefore, the scrap rate is high, and labor costs are also high, resulting in a high polishing cost. Utility Model Content
[0003] The purpose of this invention is to solve the problems existing in the prior art and provide a CNC external sanding machine for rice cooker inner pots, which can replace manual labor to complete the external polishing of rice cooker inner pots, improve processing efficiency and processing quality, and reduce production costs.
[0004] To achieve the above objectives, this utility model employs the following technical solution:
[0005] A CNC external sanding machine for rice cooker inner pot includes a frame with a cross slide mechanism on the frame. The output slide of the cross slide mechanism has a rotating support column and a first drive system for rotating the rotating support column around a vertical axis. A support frame is provided at the top of the rotating support column, and a support shaft is horizontally mounted on the support frame. A rice cooker inner pot locking clamp is provided at the front end of the support shaft, and a second drive system for rotating the support shaft is provided at the rear end. A polishing tool and a third drive system for rotating the polishing tool around a horizontal axis are provided on one side of the rice cooker inner pot locking clamp. The cross slide mechanism, the first drive system, the second drive system, and the third drive system are all connected to a control system signal.
[0006] Preferably, the polishing tool includes a grinding wheel and a sisal wheel arranged sequentially from left to right on the output shaft of the third drive system.
[0007] Preferably, the rice cooker inner pot locking clamp is a rotating body adapted to the inner cavity of the rice cooker inner pot, and an electromagnet is provided in the rotating body.
[0008] Preferably, the polishing tool is provided with a dust collection device on the side away from the locking clamp of the rice cooker inner pot.
[0009] Preferably, the frame is equipped with a lubrication system.
[0010] Preferably, the cross slide mechanism uses ball screw drives in both the horizontal and vertical directions, and is supported by linear guide rails.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This utility model discloses a rice cooker inner pot locking clamp for fixing the inner pot of a rice cooker. A third drive system drives a polishing tool to rotate around a horizontal axis to polish the inner pot. A cross slide mechanism drives the inner pot locking clamp to move in the horizontal and vertical directions. A first drive system drives a support column to rotate around a vertical axis, which in turn drives the inner pot locking clamp to rotate around the axis of the support shaft. A second drive system drives the support shaft to rotate. In conjunction with the polishing tool, four-axis linkage can be achieved to complete the polishing of the complex curved surface on the outside of the inner pot of the rice cooker. This can replace manual polishing of the inner pot, improve processing efficiency and quality, and reduce production costs. Attached Figure Description
