Description

Technical Field

[0001] The invention relates to the technical field of ball cover processing, in particular to a novel optical ball cover processing and clamping method. Background Art

[0002] When the hemispherical optical ball cover goes through the lathe process, according to the requirements of the drawing, both the flange diameter and the flange thickness (hereinafter referred to as the lowering surface) must be machined.

[0003] With the development of the optical manufacturing industry, the technical products studied are playing an increasingly important role in the information transmission and Internet of Things era. The development of the optical product dome has become more and more diversified. The current domes include U-shaped domes, semi-circular domes, deep groove domes, etc. Among them, when turning the edge of the hemispherical dome, most of them need to turn the flange edge diameter and reduce the surface. However, in the commonly used lathe process, the work is generally designed as two sets of lathe tooling, one for turning the diameter tooling and the other for reducing the surface tooling. The reason is that the flange edge plane close to the spherical surface will contact the clamping surface of the clamping device, which will affect the product size when turning the diameter.

[0009] Step 3: Use the telescopic cylinder to drive the positioning block to move to the right, expose the flange edge of the product, and start processing the product.

[0010] Furthermore, it also includes a clamping device, which includes an ejector block tooling fixed on the ejector pin at the tail of the lathe;

[0011] It also includes a placing tool, on which a positioning block is sleeved, and the positioning block is driven by a telescopic cylinder; the positioning block is provided with a receiving groove for receiving the flange edge of the product.

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] like Figure 1-Figure 3 As shown, the present invention provides a first embodiment of a novel optical ball cover processing and clamping method, the method is as follows:

[0024] Step 1: Place the spherical surface of the product in the placement groove, and use the telescopic cylinder to drive the positioning block to move to the left so that the flange edge of the product is embedded in the receiving groove;

[0025] Step 2: Then insert the right side of the top block tooling into the product ball cover to complete the clamping of the product;

[0026] Step 3: Use the telescopic cylinder to drive the positioning block to move to the right, expose the flange edge of the product, and start processing the product.

[0027] It includes a top block fixture 1 fixed on the top pin at the tail of the lathe, the right side of the top block fixture 1 is hemispherical and is used to be embedded in the product ball cover. It also includes a placement fixture 2, the left side of the placement fixture 2 has a placement groove for accommodating the product spherical surface 200. The top block fixture 1 and the placement fixture 2 clamp the left and right sides of the product respectively, so that the product can be clamped.

[0028] The placement tool 2 is provided with a positioning block 3, which is driven by a telescopic cylinder 4; the positioning block 3 has a receiving groove for receiving the flange edge 100 of the product. The spherical surface 200 of the product is placed in the placement groove, and the positioning block 3 is driven to move to the left by the telescopic cylinder 4, so that the flange edge 100 of the product is embedded in the receiving groove, and then the right side of the top block tool 1 is embedded in the product ball cover to complete the clamping of the product. When the product needs to be processed, the positioning block 3 is driven to move to the right by the telescopic cylinder 4, so that the flange edge 100 of the product can be exposed for easy processing.

[0029] A plurality of connecting columns 5 are fixed in a ring shape on the right side surface of the placing tool 2, and the right end of the connecting column 5 is fixed on the supporting plate 6; the telescopic cylinder 4 is fixed on the left side surface of the supporting plate 6, and a top plate 7 is fixed on the push rod of the telescopic cylinder 4, and a plurality of moving columns 8 are fixed in a ring shape on the left side surface of the top plate 7, and a channel for the moving column 8 to slide is opened on the placing tool 2, and the moving column 8 passes through the channel and is fixedly connected to the right side surface of the positioning block 3.

[0030] The telescopic cylinder 4 drives the top plate 7 to move, thereby driving the moving column 8 to slide in the channel, and further driving the positioning block 3 to move.

[0031] Based on the first embodiment, the present invention provides a second embodiment of a novel optical ball cover processing clamping method, wherein a clamping block 9 is fixed to the right side of the support plate 6, and the clamping block 9 is cylindrical. The cylindrical shape makes it easy to install the device on the three-jaw chuck of the lathe.

[0032] Based on any one of the above embodiments, the present invention provides a third embodiment of a novel optical ball cover processing clamping method, wherein the positioning block 3 is mounted on the placement tooling 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 moving in the channel, the linear guide rail 10 is fixed on the placement tooling 2 to cooperate with the positioning block 3.

[0033] On the basis of the second embodiment, the present invention provides a fourth embodiment of a novel optical ball cover processing and clamping method, wherein a rotary joint 12 is fixed to the right side of the support plate 6, and the rotating end of the rotary joint 12 is fixed to the right side of the support plate 6, and a first joint 13 is provided on the fixed end, and a second joint 14 is provided on the rotating end, and the first joint 13 is used to connect the air inlet pipe, and the second joint 14 is used to connect the air outlet pipe. The support plate 6 also has a through hole 15, and after one end of the air outlet pipe is connected to the second joint 14, the other end passes through the through hole 15 and is connected to the telescopic cylinder 4, so as to provide gas to the telescopic cylinder 4. When the three-jaw chuck of the lathe clamps the clamping block 9 and drives the clamping block 9 to rotate, the rotating end of the rotary joint 12 is also driven to rotate, while the fixed end does not rotate, so that the air inlet pipe on the fixed end will not be entangled and folded.

[0034] The above description is only a preferred embodiment of the present invention and should not be construed as limiting the present application. All equivalent changes and modifications made within the scope of the patent application of the present invention should fall within the scope of the present invention.
