Description

Technical Field

[0001] The utility model relates to the technical field of shell type machining equipment, in particular to a shell type machining fixing component. Background Art

[0002] Shell mold machine, also called core shooting machine, is a machine for casting shell molds using hot core box technology and phenolic resin sand coated sand as raw materials. It is particularly suitable for the production of complex thin-walled precision iron castings (such as automobile engine cylinder blocks, cylinder heads, etc.) and high-demand steel castings (such as container corners and train brake buffers; mid-shell parts, etc.), and can effectively eliminate casting defects such as sand sticking, deformation, thermal cracking and pores. It can make the surface of the casting smoother and the size more accurate, reduce or do not require mechanical processing, shorten the production cycle, save metal materials, and reduce costs; and the casting mold can be made by automatic machinery (core shooting machine must be used), and no skilled workers are required; it is especially suitable for batch and mass production of various small and medium-sized metal castings.

[0003] After searching, the patent document with the authorization announcement number CN209565470U discloses a workpiece fixing mechanism for shell-type machining. In view of the problem that the workpiece cannot be fixed during the existing shell-type machining, the following scheme is proposed, which includes a machine table, a processing head is installed on the machine table, and a processing table is arranged on the surface of the machine table. Two sets of clamping plates are movably arranged on the surface of the processing table, and the sides of the clamping plates away from each other are respectively fixedly connected with positioning blocks, and a positioning plate is movably arranged on the clamping plate, and the positioning plate is movably connected to the clamping plate through an extension rod. An adjustment slot is provided on the processing table, and a moving rod is fixedly connected to the bottom of the positioning block, and the moving rod movably passes through the adjustment slot and extends into the processing table. By setting a movable positioning plate, the workpiece can be fixed from above the workpiece to prevent the clamping plate from clamping excessively, causing the workpiece to detach from the clamping plate during the processing, thereby affecting the processing.

[0004] In actual use, it is found that the existing device cannot drive the casting to rotate after clamping it. If the casting needs to be processed on multiple sides, the casting needs to be re-clamped and fixed, which is time-consuming and labor-intensive. At the same time, there is no limiting mechanism in the fixing assembly, which causes the moving block to be not stable enough when moving, affecting the clamping effect of the casting. There are problems such as time-consuming and labor-intensive multi-sided processing of the casting and the inability to clamp the casting firmly, affecting work efficiency and clamping effect. Therefore, we propose a shell mold machine processing fixing assembly to solve the above problems. Utility Model Content
