Description

Technical Field

[0001] This utility model relates to a machining tooling, and more particularly to a compressor machining tooling, specifically a fixture that can perform machining of various compressor housings on a horizontal machining center. Background Technology

[0002] Currently, the single-screw compressor is a model with excellent theoretical performance. It not only possesses good force balance but also excels in efficiency, noise, vibration, and field maintenance. This compressor's design philosophy makes it a highly favored choice in the industrial sector.

[0003] The manufacturing process of a single-screw compressor housing requires precision machining of all six surfaces, and all holes need to be boring. Due to design differences between various compressor models, the machining dimensions of each machine tool are limited, necessitating the use of multiple specialized single-screw compressor housing machining machines to meet the needs of all products. Furthermore, ensuring machining accuracy and repeatability remains challenging. Utility Model Content

[0004] The purpose of this invention is to address the problem that the lack of versatile tooling in the machining of single-screw compressor housings necessitates the use of multiple dedicated machine tools, leading to increased equipment costs and difficulty in guaranteeing machining accuracy. The invention proposes a fixture that can perform various compressor housing machining operations on a single horizontal machining center.

[0005] The technical solution of this utility model is:

[0006] A fixture capable of machining various compressor housings on a horizontal machining center is characterized by comprising a machine tool connecting plate 1, a workpiece connecting plate 2, and a workpiece clamping support frame 3. The machine tool connecting plate 1 is fixedly mounted on the worktable of the horizontal machining center. The machine tool connecting plate 1 is provided with a connecting plate positioning pin 4, and a pin hole 5 is provided at a corresponding position on the workpiece connecting plate 2. The workpiece clamping support frame 3 is provided with a support frame positioning pin 6 that matches the pin hole 5. The compressor housing 7 is fixedly connected to the workpiece connecting plate 2 by bolts 8.

[0007] The workpiece clamping support frame 3 is assembled from a connecting plate 301 and multiple longitudinal and transverse support rods 302.

[0008] The beneficial effects of this utility model are:

[0009] This invention enables the machining of various compressor housing parts on a single horizontal machining center, thereby significantly expanding the machining range of the machine tool.

[0010] The installation of the combined fixture is carried out under the machine tool, which reduces the labor intensity of the workers and the time required for clamping, greatly reducing the workload of the workers and thus improving the processing efficiency.

[0011] 3. The tooling is highly precise, ensuring the accuracy and repeatability of workpiece processing, thereby guaranteeing the quality of the final product. Attached Figure Description
