Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for optical dome processing, and in particular to a novel clamping device for optical dome processing. Background Technology

[0002] When a hemispherical optical dome is processed on a lathe, according to the drawing requirements, both the flange diameter and the flange thickness (hereinafter referred to as the reduced surface) must be machined.

[0003] With the development of the optical manufacturing industry, its researched technologies and products are playing an increasingly important role in information transmission and the Internet of Things era. Among these, the development of optical dome covers has seen increasingly diverse evolution. Current dome covers include U-shaped dome covers, hemispherical dome covers, and deep groove dome covers. When machining the edges of hemispherical dome covers, it is often necessary to both machine the flange diameter and reduce the surface area. However, in commonly used lathe processes, the work is generally designed with two sets of lathe fixtures: one for machining the diameter and one for reducing the surface area. This is because the flange surface near the spherical surface will contact the clamping surface of the clamping fixture, thus affecting the product dimensions when machining the diameter. Utility Model Content

[0004] The purpose of this invention is to provide a novel optical dome processing clamping device that can expose the flange edge of the product during processing.

[0005] The technical solution of this utility model:

[0006] A novel optical dome processing clamping device includes a top block fixture fixed on a center pin at the tail of a lathe, and a placement fixture. A positioning block is sleeved on the placement fixture and driven by a telescopic cylinder. The positioning block has a receiving groove for accommodating the flange edge of the product.

[0007] Furthermore, a plurality of connecting columns are fixed in a ring on the right side of the placement fixture, and the right end of the connecting columns is fixed to the support plate; the telescopic cylinder is fixed on the left side of the support plate, and a top plate is fixed on the push rod of the telescopic cylinder; a plurality of movable columns are fixed in a ring on the left side of the top plate; the placement fixture is provided with a channel for the movable columns to slide, and the movable columns pass through the channel and are fixedly connected to the right side of the positioning block.

[0008] Furthermore, a clamping block is fixed to the right side of the support plate.

[0009] Furthermore, the positioning block is mounted on the placement fixture via a linear guide rail.

[0010] Furthermore, a rotary joint is fixed to the right side of the support plate, and the support plate also has a through hole.

[0011] The beneficial effects of this utility model are:

[0012] This invention exposes the flange edge of the product during processing. It effectively compensates for dimensional deviations caused by tooling positioning interference, as well as the economic losses resulting from processing with two sets of tooling. It ensures dimensional stability during product processing and reduces the defect rate. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figures 1-3 As shown, this utility model provides a first embodiment of a novel optical dome processing clamping device, including a top block fixture 1 fixed to a center pin at the tail of a lathe. The right side of the top block fixture 1 is hemispherical and is used to embed into the product dome. It also includes a placement fixture 2, the left side of which has a placement groove for accommodating the product spherical surface 200. By clamping the left and right sides of the product respectively with the top block fixture 1 and the placement fixture 2, the product can be clamped.

[0019] The placement fixture 2 is fitted with a positioning block 3, which is driven by a telescopic cylinder 4. The positioning block 3 has a receiving groove for accommodating the flange edge 100 of the product. The spherical surface 200 of the product is placed in the placement groove, and the telescopic cylinder 4 moves the positioning block 3 to the left, thereby embedding the flange edge 100 of the product into the receiving groove. Then, the right side of the top fixture 1 is embedded into the spherical cover of the product, completing the clamping of the product. When processing is required, the telescopic cylinder 4 moves the positioning block 3 to the right, thereby exposing the flange edge 100 of the product for easier processing.

[0020] The right side of the placement fixture 2 is fixed with a plurality of connecting columns 5 in a ring, and the right end of the connecting columns 5 is fixed to the support plate 6; the telescopic cylinder 4 is fixed to the left side of the support plate 6, and a top plate 7 is fixed on the push rod of the telescopic cylinder 4. A plurality of movable columns 8 are fixed in a ring on the left side of the top plate 7. The placement fixture 2 is provided with a channel for the movable columns 8 to slide, and the movable columns 8 pass through the channel and are fixedly connected to the right side of the positioning block 3.

[0021] The telescopic cylinder 4 drives the top plate 7 to move, which in turn drives the moving column 8 to slide in the channel, thereby driving the positioning block 3 to move.

[0022] Based on the first embodiment, this utility model provides a second embodiment of a novel optical dome processing clamping device. A clamping block 9 is fixed on the right side of the support plate 6. The clamping block 9 is cylindrical, and its cylindrical shape facilitates the installation of this device on a three-jaw chuck of a lathe.

[0023] Based on any of the above embodiments, the present invention provides a third embodiment of a novel optical dome processing clamping device. The positioning block 3 is sleeved on the placement fixture 2 via a linear guide rail 10. Since the moving column 8 can slide in the channel, there is a gap between the moving column 8 and the channel. In order to prevent the moving column 8 from moving up and down when it moves in the channel, the linear guide rail 10 is fixed on the placement fixture 2 to cooperate with the positioning block 3.

[0024] Based on the second embodiment, this utility model provides a fourth embodiment of a novel optical dome processing clamping device. A rotary joint 12 is fixed to the right side of the support plate 6. The rotating end of the rotary joint 12 is fixed to the right side of the support plate 6. The fixed end has a first connector 13, and the rotating end has a second connector 14. The first connector 13 is used to connect to an air inlet pipe, and the second connector 14 is used to connect to an air outlet pipe. The support plate 6 also has a through hole 15. One end of the air outlet pipe is connected to the second connector 14, and the other end passes through the through hole 15 and connects to the telescopic cylinder 4 to supply gas to the telescopic cylinder 4. When the lathe's three-jaw chuck clamps the clamping block 9, it drives the clamping block 9 to rotate, simultaneously driving the rotating end of the rotary joint 12 to rotate, while the fixed end does not rotate, preventing the air inlet pipe on the fixed end from becoming tangled or kinked.

[0025] The above description is only a preferred embodiment of the present utility model and should not be construed as a limitation of this application. All equivalent changes and modifications made within the scope of the patent application of the present utility model should be included in the scope of the present utility model.
