Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical processing, and in particular relates to a clamp for processing a pot liner. Background Art
[0002] Currently, the inner pots of rice cookers on the market are primarily made of aluminum alloy. Aluminum alloy offers advantages such as light weight and good thermal conductivity, and can also be non-stick when coated. However, due to mechanical action, the chemical materials or aluminum elements present in the coating can easily enter the human body, posing a health hazard. The use of ceramic inner pots overcomes the shortcomings of aluminum inner pots, such as sticking to the bottom, difficulty in rinsing, and harmful to the human body. However, ceramic inner pots deform significantly during the forming and sintering process, resulting in low dimensional and shape accuracy. Therefore, ceramic inner pots must be further processed to be optimally utilized. The spherical surface of the ceramic inner pot bottom must be machined to achieve uniform wall thickness and ensure a good fit with the heat transfer iron. Due to the hard and brittle nature of ceramic and its low dimensional and shape accuracy, the machining of ceramic inner pots is primarily subject to uneven force, limited clamping force, and significant deviations in the size, shape, and position of the blank, compared to conventional metal part machining. Therefore, a fixture suitable for machining the spherical surface of the ceramic inner pot bottom is urgently needed. Utility Model Content

[0004] The technical solution adopted by the utility model is a fixture for processing the inner wall of a pot, which is characterized by comprising a positioning base, an end surface positioning disk, a pad, an axial positioning device and a radial positioning fixture. The center of the positioning base is fixedly connected to the end surface positioning disk, the center of the upper surface of the end surface positioning disk is vertically provided with an axial positioning device, and at least three radial positioning fixtures are evenly arranged on the inner surface of the positioning base in the circumference, which can be used to fix the outer wall of the pot to be processed. The radial positioning fixture is fixed to the end surface positioning disk through the pad.
[0005] The pad is provided with U-shaped grooves on the left and right sides of the center, which can be used to fix the radial positioning fixture and for moving the radial positioning fixture back and forth in the U-shaped groove for positioning. When used to process pots of different sizes, it can be adaptively moved to ensure processing needs. The radial positioning fixture includes a fixed seat, a handle, a guide rod, a sleeve, and a pressure head. The fixed seat is fixedly connected together by two L-shaped fixing plates back to back. The fixed seat can be fixed to the pad by bolts, and a guide rod is provided on the right top of the fixed seat. The lower left part of the fixed seat is fixedly connected to the handle, the guide rod is provided with a sleeve in the vertical direction, and a detachable pressure head is provided on the sleeve. The pressure head material of the radial positioning fixture is a flexible material.
[0006] Specifically, the axial positioning device can be welded on the end face positioning plate to fix the inner wall of the pot liner to be processed, ensuring that the workpiece is concentric with the main axis of the machine tool, the force is evenly distributed, and the bottom surface is parallel to the positioning surface. The end face of the processed workpiece is flat and the thickness is uniform, thereby ensuring the axial processing accuracy.
[0007] Specifically, the pressure head material is polyurethane or silicone, and the three radial positioning fixtures have strong and uniform clamping forces in the circumferential direction of the positioning base. Because the pressure head of the radial positioning fixture is a flexible fixture, the clamping force has a floating function, which makes clamping convenient and reliable without damaging the outer surface of the workpiece, reducing the labor intensity of workers.
[0008] Specifically, a fastening sleeve can be sleeved on the outer circumference of the end surface positioning plate, and the sleeve can be used to process pots of different sizes.
[0009] Specifically, the fixing plate is provided with two small holes, which can be used to fix the fixing seat to the pad.
[0010] The beneficial effects of the utility model are:
[0011] 1. The design structure of the utility model is reasonable and simple. The axial positioning device ensures that the workpiece is concentric with the main shaft of the machine tool. The end face of the processed workpiece is flat and the thickness is uniform, which ensures the axial processing accuracy, that is, ensures the quality of the pot processing.
[0012] 2. By adopting radial positioning fixtures, the three radial positioning fixtures have strong and uniform clamping forces in the circumferential direction of the positioning base. Moreover, because the positioning clamps of the radial positioning fixtures are flexible fixtures, the clamping force has a floating function. The clamping is convenient and reliable without damaging the outer surface of the workpiece, ensuring the production quality of the pot while reducing the labor intensity of workers and improving production efficiency.
