Abstract
Description
Technical Field
[0001] This invention relates to the field of optical dome processing technology, and in particular to a novel clamping method for processing optical domes. 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 device, thus affecting the product dimensions when machining the diameter. Summary of the Invention
[0004] The purpose of this invention is to provide a novel method for clamping optical dome processing, which can expose the flange edge of the product during processing.
[0005] The technical solution of the present invention:
[0006] A novel method for clamping and processing optical domes is described below:
[0007] Step 1: Place the spherical surface of the product into the placement groove, and use the telescopic cylinder to move the positioning block to the left so that the flange edge of the product is embedded into the receiving groove;
[0008] Step 2: Then, insert the right side of the top block fixture into the product spherical cover to complete the clamping of the product;
[0009] Step 3: Move the positioning block to the right using the telescopic cylinder to expose the flange edge of the product and begin processing the product.
[0010] Furthermore, it also includes a clamping device, which includes an ejector block fixture fixed to the ejector pin at the tail of the lathe.
[0011] It also includes a placement fixture, on which a positioning block is fitted, the positioning block being driven by a telescopic cylinder; the positioning block having a receiving groove for accommodating the flange edge of the product.
[0012] 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.
[0013] Furthermore, a clamping block is fixed to the right side of the support plate.
[0014] Furthermore, the positioning block is mounted on the placement fixture via a linear guide rail.
[0015] Furthermore, a rotary joint is fixed to the right side of the support plate, and the support plate also has a through hole.
[0016] The beneficial effects of this invention are:
[0017] 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. This ensures dimensional stability of the product and reduces the defect rate. Attached Figure Description

Detailed Implementation
[0022] The invention will now be further described with reference to the accompanying drawings.
[0023] like Figures 1-3 As shown, the present invention provides a first embodiment of a novel optical dome processing clamping method, the method being as follows:
[0024] Step 1: Place the spherical surface of the product into the placement groove, and use the telescopic cylinder to move the positioning block to the left so that the flange edge of the product is embedded into the receiving groove;
[0025] Step 2: Then, insert the right side of the top block fixture into the product spherical cover to complete the clamping of the product;
[0026] Step 3: Move the positioning block to the right using the telescopic cylinder to expose the flange edge of the product and begin processing the product.
[0027] The device includes a top block fixture 1 fixed to the tailstock of a lathe. The right side of the top block fixture 1 is hemispherical and is used to embed into the spherical cover of the product. It also includes a placement fixture 2, the left side of which has a placement groove for accommodating the spherical surface 200 of the product. By clamping the left and right sides of the product with the top block fixture 1 and the placement fixture 2 respectively, the product can be clamped.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] Based on the first embodiment, the present invention provides a second embodiment of a novel optical dome processing clamping method. 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 the device on a three-jaw chuck of a lathe.
[0032] Based on any of the above embodiments, the present invention provides a third embodiment of a novel optical dome processing clamping method. 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.
[0033] Based on the second embodiment, this invention provides a fourth embodiment of a novel optical dome processing clamping method. 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.
[0034] The above description is only a preferred embodiment of the present invention and should not be construed as a limitation of this application. All equivalent changes and modifications made in accordance with the scope of the patent application of the present invention should be covered by the present invention.
