Abstract
Description
Technical Field
[0001] The utility model relates to an airbag polishing grinding head. Background Art
[0002] Airbag polishing is a novel polishing method, which is very suitable for polishing aspherical optical lenses. The principle of airbag polishing technology is as follows: applying the blowing pressure of compressed air to the airbag, so that the airbag polishing head generates a stable pressure, and combining with the polishing liquid to efficiently and stably remove the surface material of the optical lens, so that the optical lens has a certain precision surface shape and surface roughness. However, in the existing airbag polishing technology, generally, the airbag polishing head needs to be replaced after being used for a period of time, and the airbag polishing head can only be purchased from the original manufacturer or mass-produced by designing a mold. Generally, several airbag polishing heads of different sizes are required to produce one product, and the number of airbag polishing heads used is relatively large, which greatly increases the use cost of the airbag polishing head, and further increases the overall production cost of the product. Therefore, how to reduce the use cost of the airbag polishing head has become an urgent technical problem to be solved, and this case is thus born. Content of the Utility Model
[0003] The utility model makes improvements to the above-mentioned problems existing in the prior art, that is, the technical problem to be solved by the utility model is to provide an airbag polishing grinding head, which is reasonably designed and reduces costs.
[0004] In order to achieve the above purpose, the technical scheme adopted by the utility model is: an airbag polishing grinding head, including an airbag head arranged on a polishing head tooling, a polyurethane polishing skin is arranged on the surface of the airbag head, the polyurethane polishing skin is pressed by a pressing ring, and a nut for pressing the pressing ring is screwed on the outer side of the polishing head tooling.
[0005] Further, the pressing ring is sleeved on the outer side of the airbag head.
[0006] Further, a pressing cone surface in contact with the polyurethane polishing skin is arranged at one end of the inner cavity of the pressing ring away from the polishing head tooling.
[0007] Further, a ring-shaped first pressing flange is arranged on the outer peripheral side of the pressing ring; a ring-shaped second pressing flange is arranged at one end of the inner hole of the nut away from the polishing head tooling, and the second pressing flange is pressed on the first pressing flange.
[0008] Further, an internal thread is arranged on the peripheral side of the inner hole of the nut; an external thread for cooperating with the internal thread is arranged on the outer peripheral side of the polishing head tooling.
[0009] Compared with the prior art, the utility model has the following effects: The structure of the utility model is designed simply and reasonably.

[0016] The following further describes the utility model in detail with reference to the drawings and specific embodiments.
[0017] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.
[0018] Such as Figures 1 to 6As shown in the figure, a pneumatic polishing grinding head of the present utility model mainly solves the problem of high use cost of the pneumatic polishing head. It includes a pneumatic head 2 arranged on a polishing head tooling 1. The polishing head tooling 1 is used to connect with an external device. The interior of the polishing head tooling 1 has an air passage 3 communicating with the pneumatic head 2 for connecting with an external pressure air source. This part of the structure is prior art. The improvement compared with the existing pneumatic polishing head lies in that: a polyurethane polishing skin 4 is arranged on the spherical surface of the pneumatic head 2. The polyurethane polishing skin 4 is pressed tightly by a pressing ring 5. A nut 6 for pressing the pressing ring 5 tightly is screwed on the outer side of the polishing head tooling 1. During use, only need to place the polyurethane polishing skin on the pneumatic head with the pressing ring. The replacement process is fast and simple. During the use process, only need to replace the polyurethane polishing skin, without replacing the whole pneumatic polishing head, realizing that one pneumatic head can be reused, without the need to mold the pneumatic head and stick the polyurethane polishing skin with glue, saving the mold cost and the purchase cost of a large number of pneumatic polishing heads.
[0019] In this embodiment, the pressing ring 5 is coaxially sleeved on the outer side of the pneumatic head 2. Further, in order to improve the pressing effect, a pressing cone surface 7 in contact with the polyurethane polishing skin 4 is provided at one end of the inner cavity of the pressing ring 5 far from the polishing head tooling 1. When the pressing ring is sleeved on the outer side of the pneumatic head, the pneumatic head penetrates the inner cavity of the pressing ring, and the pressing cone surface in the inner cavity of the pressing ring contacts the polyurethane polishing skin.
[0020] In this embodiment, a ring-shaped first pressing flange 8 is coaxially provided on the outer peripheral side of the pressing ring 5; a ring-shaped second pressing flange 9 is coaxially provided at one end of the inner hole of the nut 6 far from the polishing head tooling 1. When the nut 6 is screwed on the polishing head tooling 1, the second pressing flange 9 presses on the first pressing flange 8, thereby realizing the pressing of the pressing ring, and further enabling the pressing cone surface of the pressing ring to press the polyurethane polishing skin tightly.
[0021] In this embodiment, an internal thread 10 is provided on the circumferential side of the inner hole of the nut 6; an external thread 11 for cooperating with the internal thread 10 is provided on the outer peripheral side of the polishing head tooling 1.
[0022] Specific implementation process: First, place the polyurethane polishing skin 4 on the surface of the pneumatic head 2; then place the pneumatic head 2 on the pressing ring 5 so that the pressing ring 5 is sleeved on the outer side of the pneumatic head 2; then place the pneumatic head 2 sleeved with the pressing ring 5 on the polishing head tooling 1; finally, sleeve the nut 6 on the outer side of the polishing head tooling 1 and lock it, use the nut 6 to fix and press the pressing ring 5, and press the polyurethane polishing skin 4 tightly through the pressing ring 5.
[0023] In the actual use process, it is calculated that the number of airbag heads of each specification consumed by a numerically controlled polishing equipment throughout the year is about 1,800. In this application, only a polyurethane polishing leather with a cost of 2 - 5 yuan per piece is needed between the pressing ring and the airbag head, which can replace the airbag polishing head with a price of 700 - 1,000 yuan per piece of the original manufacturer, saving a large amount of cost and well solving the problem of high use cost of the airbag polishing head.
[0024] If the present utility model discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), or can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integral structure (for example, manufactured integrally by casting process) (except where it is obviously impossible to adopt the integral forming process).
[0025] In addition, the terms used to represent the positional relationship or shape in any of the technical solutions disclosed in the present utility model, unless otherwise stated, include states or shapes that are approximate, similar or close to it.
[0026] Any component provided by the present utility model can either be assembled from a plurality of separate components or be a single component manufactured by an integral forming process.
[0027] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit it; although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the specific implementation manners of the present utility model or make equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present utility model, they should all be covered within the scope of the technical solutions claimed by the present utility model.
