DETAILED DESCRIPTION
[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0025] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.
[0026] The cup body polishing machine includes a fixture and a polishing mechanism. The fixture includes a bracket 1. The bracket 1 is provided with an upper fixture 11 and a lower fixture. The upper fixture 11 can move up and down on the bracket 1. When the cup body 2 is placed on the lower fixture, the upper fixture 11 moves down to clamp the cup body 2.
[0027] The lower clamp is detachably connected to the bracket 1 . A connecting seat 12 is provided on the bracket 1 . The lower clamp is detachably connected to the connecting seat 12 . Lower clamps of different sizes can be used according to different cup bodies 2 or cup types.
[0028] This embodiment mainly describes the structure of the clamp, which is as follows:
[0029] The automatic polishing machine thermos cup cup clamp comprises a base 3, a cushion block 4 and a limiter 5. The base 3, the cushion block 4 and the limiter 5 are detachably connected, and the cushion block 4 is clamped between the base 3 and the limiter 5.
[0030] The cushion block 4 is provided with a through hole 41 , the base 3 is provided with an inserting portion 31 matched with the through hole 41 , and the base 3 is also provided with a step 32 . After the cushion block 4 is sleeved on the inserting portion 31 through the through hole 41 , the cushion block 4 abuts against the step 32 .
[0031] The height of the insertion portion 31 is smaller than the height of the through hole 41 , preventing the insertion portion 31 from protruding from the through hole 41 .
[0032] An assembly groove 42 is formed on the upper surface of the cushion block 4 , and the limiting member 5 is disposed in the assembly groove 42 .
[0033] The limiting member 5 is provided with two positioning holes 51 , and the base 3 is provided with two fixing holes 33 corresponding to the positioning holes 51 . After the screws 55 are inserted from the positioning holes 51 , they pass through the fixing holes 33 and are tightened with the connecting seat 12 , so that the lower clamp is firmly fixed on the connecting seat 12 .
[0034] A rubber gasket 6 is provided between the base 3 and the cushion block 4 . The rubber gasket 6 is sleeved on the lower end of the cushion block 4 . An abutment surface 43 is provided on the upper surface of the cushion block 4 . After the cushion block 4 and the base 3 are fixed, the rubber gasket 6 is attached to the abutment surface 43 .
[0035] The outer diameter of the rubber gasket 6 is larger than that of the stopper 5 . After the cup body 2 is sleeved on the stopper 5 , the mouth of the cup body 2 can rest against the rubber gasket 6 to prevent the mouth of the cup from contacting the cushion block 4 and causing wear.
[0036] During polishing, the pad 4 will also contact with the polishing disc, causing the polishing disc to wear the pad 4. When the pad 4 is worn out to the extent that it cannot be used, only the pad 4 needs to be replaced, thereby further saving production costs.
[0037] The material of the pad 4 is stainless steel. Preferably, the material of the pad 4 is generally CR12 steel or tungsten steel. The material to be selected is determined according to the specifications of the polishing disc. Tungsten steel has better wear resistance than CR12 steel. When the strength of the polishing disc is low, the cup body 2 is generally rough ground, and CR12 steel can be used. When the strength of the polishing disc is high, the cup body 2 is generally polished with high precision, and tungsten steel is used, which is more wear-resistant.
[0038] A fluororubber sleeve 7 is sleeved on the limiting member 5, and the fluororubber sleeve 7 covers the side wall of the limiting member 5. Furthermore, an annular slot 53 is opened on the outer wall of the limiting member 5, and an annular protrusion 71 is provided on the inner wall of the fluororubber sleeve 7. After the fluororubber sleeve 71 is sleeved on the limiting member 5, the annular protrusion 71 is stuck in the annular slot 53, so that the connection between the fluororubber sleeve 7 and the limiting member 5 is more stable, preventing the fluororubber sleeve 7 from falling off.
[0039] When the cup body 2 is sleeved on the limiting member 5, the inner wall of the cup mouth of the cup body 2 is attached to the fluororubber sleeve 7. The fluororubber sleeve 7 can prevent the inner wall of the cup mouth of the cup body 2 from being worn, and can also seal the cup mouth to prevent dust or debris formed by polishing from entering the cup body 2.
[0040] The side wall of the limiting member 5 is provided with a guiding inclined surface 54 , and the side wall of the limiting member 5 is inclined outward from top to bottom, so as to facilitate the cup body 2 to be sleeved on the limiting member 5 .
[0041] In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.
[0042] The above is a detailed introduction to the automatic polishing machine thermos cup clamp provided by the utility model. This article uses specific examples to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
