Description

Technical Field

[0001] This utility model relates to a pipe shell clamping fixture for an automatic sandblasting machine, and particularly to a device for quick replacement of sandblasting fixtures and clamping multiple types of pipe shells. Background Technology

[0002] Currently, many critical industries have significantly increased reliability requirements for equipment, with some components requiring metal housings. This increased demand has led to a substantial rise in the demand for metal housings. Due to the wide variety of housing models produced, automatic sandblasting machines require clamping fixtures, making frequent fixture changes difficult. Currently, housing manufacturers use manual sandblasting machines for surface treatment of metal housings, resulting in slow operation and impacting production schedules. To improve efficiency, automatic sandblasting machines have been introduced. However, the clamping fixtures on these machines are typically fixed directly to a small turntable with screws. When encountering a housing that the fixture cannot hold, the screws must be removed and a new fixture installed, a method that is inefficient. Furthermore, existing clamping fixtures, such as stud clamps, obstruct the appearance of the housing; or each component requires a dedicated fixture, limiting its versatility to a single size of housing.

[0003] The main factors affecting sandblasting efficiency include sandblasting intensity, rotation speed, abrasive grade, and ease of tooling change. Due to limitations imposed by the properties of the casing material, only changes in tooling do not affect the overall quality of the casing.

[0004] Existing technologies suffer from slow tooling changes, and the tooling cannot fully meet the requirements for pipe shell sandblasting. When sandblasting various types of pipe shells, frequent tooling changes result in low work efficiency. Utility Model Content

[0005] The technical problem this invention aims to solve is, in general, to provide a pipe shell clamping fixture for an automatic sandblasting machine. This invention allows for quick fixture changes, and each fixture can clamp multiple types of pipe shells. This saves time on fixture changes and improves efficiency.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] A pipe casing clamping fixture for an automatic sandblasting machine is disclosed. The fixture consists of a universal base and a dedicated clamping fixture. The universal base serves as the foundation for all fixtures, ensuring secure support and fastening, while also allowing for easy and quick fixture replacement. Therefore, the universal base features a structure with protruding sides and a recessed center. Studs, wing nuts, and pressure plates are installed on the protruding sides, facilitating the quick and easy installation and removal of the dedicated clamping fixture via the pressure plates. The recessed center is designed with countersunk holes, allowing the base to be fixed to the sandblasting machine turntable without interfering with the installation of the dedicated fixture.

[0008] The specialized clamping fixture is designed for magnetic adsorption. Made of aluminum, the fixture is thin on both sides for easy mounting to a base. It features a central bulge with multiple small cylindrical countersunk holes machined inside. These holes open at the bottom of the fixture, leaving a 0.8mm gap between the holes and the top aluminum surface. In use, magnets are inserted into the cylindrical holes, the bottom is supported by an aluminum plate, and the tube is placed on the upper surface of the fixture. The magnetic attraction secures the tube to the fixture. Any tube that can be magnetically attracted can be used. This installation method is convenient, quick, and does not damage the tube. The fixture contains multiple cylindrical holes, allowing adjustment of the number of magnets to accommodate tubes of different sizes. The mounting surface can be a large flat surface or multiple small flat surfaces, facilitating the attachment of tubes with leads.

[0009] The universal base is fixed to the small turntable of the sandblasting machine with screws, rotates with the small turntable, and serves as the base for the special tooling, and is not removed.

[0010] The specialized clamping fixture is fixed to the base by nuts and pressure plates, and is used to clamp the tube shell, rotating with the base. Different types of tube shells are clamped using different specialized fixtures.

[0011] The pressure plate and nut on the universal base of this utility model can quickly fix the special tooling. The protrusions at both ends of the bottom of the special clamping tooling can restrict the movement of the tooling and ensure the accuracy of the tooling positioning. The multiple cylindrical hole structure of the special tooling can flexibly arrange the number and position of magnets, which is convenient for fixing various tube shells.

[0012] This utility model features a unique and practical design. The nuts and pressure plates on a universal base allow for quick replacement of specialized clamping fixtures. The multi-hole structure of the specialized clamping fixture allows magnets to be combined according to different tube shells, achieving effective clamping. This accelerates fixture changeover, enabling the use of the same fixture for different tube shells, reducing the variety of fixtures, and ultimately improving sandblasting efficiency.

[0013] This utility model has a simple structure, is easy to use, and has the advantages of practical function, low cost, easy operation, and improved sandblasting efficiency. Attached Figure Description
