Abstract
Description
Technical Field
[0001] This invention belongs to the field of ball cover clamping fixture technology, and in particular, an adjustable ball cover deep groove material head clamping fixture. Background Technology
[0002] 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, semi-circular dome covers, and deep groove dome covers. This invention provides a clamping fixture used to prevent the top cover with a protruding part from splashing and damaging the product during CNC machining of the top cover according to customer drawings for U-shaped deep groove dome covers. In existing technologies, when CNC machining U-shaped and semi-circular dome covers, the fixture's groove is mostly used to position the plastic part, and negative pressure suction is used to fix the part at the bottom. However, the contour of the plastic part may have a dimensional error of ±0.1mm due to factors such as material and equipment parameters. Since the dimensions of the plastic part are fixed when the tooling is positioned, the processing dimensions will vary with the contour tolerance of the product plastic part. Furthermore, when processing the sprue of the deep groove ball cover, the top cover will fly out like debris the moment it is processed off, which will damage the inner wall of the deep groove ball cover, greatly affecting the product yield and pass rate. Moreover, the existing clamping tooling cannot adapt to products of different heights. Summary of the Invention
[0003] To address the technical problem that the aforementioned clamping fixture structure cannot adapt to different heights, this invention provides an adjustable ball-shaped deep groove material head clamping fixture.
[0004] The technical solution of the present invention is as follows:
[0005] This adjustable ball cover deep groove material head clamping fixture includes a base with an open cavity inside. A horizontally arranged first cylinder outer bushing is fixed inside the cavity, and a support plate is fixed at the cavity opening. A second cylinder outer bushing is arranged above the first cylinder outer bushing, and a clamping cylinder is fixed on the second cylinder outer bushing. The end of the clamping cylinder clamps and connects to the ball cover product. A support column is fixed below the first cylinder outer bushing, and a connecting rod is hinged to the support column. One end of the connecting rod is connected to an adjusting screw, and the other end of the connecting rod is connected to a top column. The adjusting screw is vertically arranged and passes through the support plate, and the top column passes through the first cylinder outer bushing and is fixedly connected to the second outer bushing.
[0006] Furthermore, the first cylinder outer bushing has a vertically arranged side plate, and the side plate is provided with screws for limiting the second cylinder outer bushing.
[0007] Furthermore, the clamping cylinder is a three-jaw cylinder, and the three-jaw cylinder is connected to a three-jaw clamping block.
[0008] Furthermore, the connecting rod is hinged to the top column.
[0009] Furthermore, the base is made of nylon.
[0010] Furthermore, the base has access points on its lower and side surfaces for installation and maintenance.
[0011] Furthermore, the clamping method includes the following steps: Step 1, adjusting the height of the clamping cylinder using the adjusting screw, connecting rod, support column and top column; Step 2, clamping the connecting ball cover product using the end of the clamping cylinder; Step 3, processing the ball cover product after clamping.
[0012] The present invention has the following beneficial effects: The present invention provides an adjustable ball-shaped deep groove material head clamping fixture, which uses an adjusting screw, connecting rod, support column and top column to adjust the height of the clamping cylinder to match products of different heights; it can effectively compensate for the dimensional deviation caused by the shape tolerance of plastic parts, ensure the stability of product processing dimensions, prevent the material head from flying out during processing, thereby preventing the material head from damaging the product, avoiding batch defects and reducing the defect rate.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0018] Please see Figure 1-2As shown, in one embodiment of the present invention, a base is included, the base having an open cavity, a horizontally arranged first cylinder outer bushing is fixed inside the cavity, and a support plate is fixed at the opening of the cavity; a second cylinder outer bushing is arranged above the first cylinder outer bushing, a clamping cylinder is fixed on the second cylinder outer bushing, and a ball cover product is clamped and connected to the end of the clamping cylinder; a support column is fixed below the first cylinder outer bushing, the support column is hinged to a connecting rod, one end of the connecting rod is connected to an adjusting screw, and the other end of the connecting rod is connected to a top column; the adjusting screw is vertically arranged and passes through the support plate, and the top column passes through the first cylinder outer bushing and is fixedly connected to the second outer bushing.
[0019] The base provides a fixed position for the clamping cylinder structure and adjustment mechanism; the support plate mainly provides support force during product processing and provides a cavity for the cylinder installation space; the outer bushing of the first cylinder is installed on the base, and the inner wall allows the outer bushing of the second cylinder to move inside, and the screw can be used to position the cylinder height; the clamping cylinder is installed on the outer bushing of the second cylinder, and the ball cover product has a pull pin, which the clamping cylinder holds to prevent splashing during processing; the connecting rod connects the top column and the adjusting screw, and is hinged to the support column, which provides a fulcrum and acts as a lever fulcrum; the adjusting screw provides an adjustable and quantifiable downward force, and the top column pushes against the outer bushing of the second cylinder through the lever action, causing it to rise inside the outer bushing of the first cylinder; thereby driving the clamping cylinder to rise, and the lifting and lowering of the clamping cylinder can be adjusted through the above operation.
[0020] Please see Figure 1-2 As shown, in another embodiment of the present invention, the first cylinder outer bushing has a vertically arranged side plate, and the side plate is provided with screws for limiting the second cylinder outer bushing. The side plate can apply clamping force through the screws to clamp the second cylinder outer bushing. The second cylinder outer bushing is fixedly connected to the clamping cylinder, so that it will not shift and can only move in the vertical direction, maintaining stability during operation.
