Description

Technical Field

[0001] This utility model relates to the field of crucibles, and more particularly to a positioning mechanism for positioning from inside a crucible. Background Technology

[0002] In existing technologies, during the graphitization sintering process of artificial graphite production, the crucible, as the core container for containing and protecting materials, plays a decisive role in production efficiency and product quality due to its performance and service life. The filling material on the outer wall of the crucible occupies a crucial position in the entire process; it not only provides support and protection for the crucible but also influences its heat transfer, temperature distribution, and mechanical properties.

[0003] However, the type and quality of the crucible filler can affect the degree to which it adheres to the crucible wall after sintering. If filler adheres to the outer wall of the sintered crucible, it must be cleaned; otherwise, it will adversely affect the performance of the material in the next sintering and the service life of the crucible.

[0004] Our company has developed a crucible outer wall cleaning machine specifically for cleaning adhering materials from the outer walls of crucibles. During use, we discovered that the adhering material on the outer walls of some crucibles was extremely severe, with continuous clumps of material forming along a large area from top to bottom. This situation negatively impacted the original design's method of clamping and positioning the crucible from its outer wall. During clamping, one side was clamped to the outer wall while the other side was clamped to the adhering material, causing a misalignment between the center of the crucible and the center of the clamping mechanism after clamping. This misalignment affects subsequent operations of the automated equipment. Utility Model Content

This deviation of the crucible from the positioning center affects subsequent operations of the automated equipment.

[0006] The technical solutions adopted in the embodiments of this application are as follows.

[0007] A positioning mechanism for positioning from inside a crucible includes a mounting plate, a lifting rod that limits the position of the mounting plate, a cylinder mounted on the mounting plate, a positioning device for positioning the crucible, a push plate mounted on the actuating end of the positioning device, and a dustproof plate to prevent dust from entering the positioning device; the positioning device has several sets of actuating ends; one end of the lifting rod is connected to the frame of an outer wall cleaning machine; the positioning device is located on the actuating end of the cylinder; several sets of push plates are arranged in a circumferential array; and the dustproof plate is located between two sets of actuating ends of the positioning device.

[0019] This application provides a positioning mechanism for positioning from inside the crucible, solving the problem in the prior art where, during the clamping process, one side is clamped to the outer wall of the crucible while the other side is clamped to the adhesive material on the outer wall, causing the center position of the crucible to deviate from the center position of the clamping mechanism after clamping. This deviation of the crucible from the positioning center affects subsequent operations of the automated equipment.

[0020] The technical solution in this application embodiment is to solve the above problems, and the overall idea is as follows:

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] A positioning mechanism for positioning from inside a crucible includes a mounting plate 108, a lifting rod 101 that limits the position of the mounting plate 108, a cylinder 104 mounted on the mounting plate 108, a positioning device 105 for positioning the crucible, a push plate 106 mounted on the working end of the positioning device 105, and a dustproof plate 107 for preventing dust from entering the positioning device 105. The positioning device 105 has several sets of working ends. One end of the lifting rod 101 is connected to the frame of an outer wall cleaning machine. The positioning device 105 is mounted on the working end of the cylinder 104. Several sets of push plates 106 are arranged in a circumferential array. The dustproof plate 107 is located between the working ends of two sets of positioning devices 105.

[0023] The hanger 101 is provided with several sets.

[0024] The mounting plate 108 is equipped with a protective plate 102 for the protective cylinder 104.

[0025] The mounting plate 108 is equipped with a dust cover 103 that protects the push rod of the cylinder 104 and the guide shaft; one end of the dust cover 103 is connected to the mounting plate 108, and the other end of the dust cover 103 is connected to the positioning device 105.

[0026] Dust cover 103 is retractable.

[0027] The push plate 106 is made of rubber.

[0028] The positioning device 105 is circular, and its size is slightly smaller than the inner diameter of the crucible. Telescopic cylinders distributed in four directions (front, back, left, and right) are mounted on the base plate of this mechanism. At the end of each cylinder is a push plate 106 with the same curvature as the inner diameter of the crucible.

[0029] Furthermore, the lifting rod 101 is a threaded lifting rod, with its lower end fixed to the mounting plate 108 and its upper end connected to the frame of the external wall cleaning machine; the cylinder 104 is mounted on the mounting plate 108, and the push rod of the cylinder 104, together with the auxiliary guide shaft, is connected to the positioning device 105 below. To protect the cylinder 104, we used a protective plate 102; and for the push rod and guide shaft of the cylinder 104, a dust cover 103 is used for protection.

[0030] Workflow description:

[0031] Initial state: In the initial stage, the four telescopic cylinders on cylinder 104 and positioning device 105 are all in the retracted state.

[0032] Positioning mechanism enters the crucible: When the crucible moves to below the positioning device 105, the lifting cylinder 104 begins to descend, slowly sending the positioning device 105 into the crucible.

[0033] Positioning is achieved by extending the push plates: Subsequently, the cylinders in four directions are activated, causing all the push plates 106 fixed to the cylinder ends to extend. Since the push plates 106 have the same curvature as the inner diameter of the crucible, the four push plates 106 can be combined to form a circle with the same inner diameter as the crucible. If the crucible is not in the center of the positioning mechanism at this time, the crucible will be displaced under the combined force of the four push plates 106 until precise positioning is achieved.

[0034] Maintaining Positioning and Cleaning Operation: After positioning is completed, the positioning device 105 maintains the current positioning state, and at this time the outer wall cleaning machine begins to clean the crucible.

[0035] Positioning mechanism reset: After the cleaning work is completed, the four-way cylinder on the positioning device 105 retracts first, and then the cylinder 104 also retracts.

[0036] Cyclic operation: Once the next crucible to be cleaned reaches the designated position, repeat all the above actions.

[0037] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
