Work fixture for machining inner cavities and joint closing surfaces of glass molds

Abstract

The invention discloses a work fixture for machining inner cavities and joint closing surfaces of glass molds, and belongs to the technical field of work fixtures. The work fixture comprises a bottom seat plate, a middle seat plate, a movable seat, a fixed seat, a traction screw of the movable seat and mold clamping mechanisms; a first adjusting groove, a second adjusting groove and a third adjusting groove are arranged on one side of the bottom seat plate; the middle seat plate is positioned in the center of the bottom seat plate, one end of the middle seat plate is fixed to the first adjusting groove, and the other end of the middle seat plate is fixed to the second adjusting groove; the movable seat is arranged at one end of the middle seat plate, the fixed seat is fixed to the other end of the middle seat plate, an inclined plane of the movable seat is formed on one side of the movable seat, an inclined plane of the fixed seat is formed on one side of the fixed seat, and the inclined plane of the movable seat and the inclined plane of the fixed seat form a V shape; one end of the traction screw of the movable seat is connected with the movable seat, and the other end of the traction screw of the movable seat is supported on the fixed seat; and one mold locking mechanism is positioned on one side of the middle seat plate, the other mold locking mechanism is positioned on the other side of the middle seat plate, and the mold locking mechanisms are respectively fixed to the third adjusting groove. The work fixture has the advantages that the work fixture is simple in structure, convenient to manufacture, quick in operation and good in clamping effect, and tends to be maintenance-free, and loosening is prevented during machining.

Description

technical field [0001] The invention belongs to the technical field of tooling fixtures, and in particular relates to a tooling fixture for processing glass mold inner cavities and joint surfaces. Background technique [0002] Fixtures play a very important role in the production of industrial products, and the processing of glass molds is no exception. The so-called tooling fixture refers to special equipment or tools used to clamp or position workpieces in machining to meet certain process requirements. Fixtures usually need to meet the requirements of no interference during product production, accurate and reliable positioning, and convenient operation. Since the tooling fixture has the exclusive characteristics of manufacturing a certain product, the degree of generalization is low, and it is often made by the manufacturer of the product. Glass mold manufacturers are also mostly equipped with various tooling fixtures in a self-made way. In recent years, although all ki...

Problems solved by technology

[0005] Typical such as CN102380777B, CN102350650B and CN102423859B disclosed respectively "clamp device for glass mold processing", "clamp device for glass mold processing" and "clamp device for glass mold processing". Reliable clamping under the condition that the mold cavity faces upwards, so that the joint surface and the mold cavity can be processed by a machining center such as a CNC machine tool, but the three patent solutions have the following shortcomings: First, due to the need to pass through a pair of horizontal The adjustment mechanism contacts the surface of both sides of the glass mold in the length direction to adjust the horizontal state of the glass mold, and because it is necessary to manually operate the clamp drive mechanism, the clamp drive mechanism drives a pair of clamps (the patent is called the first clamp and the second clamp), a pair of clamp clamps the two ends of the glass mold until a pair of pressure plates press the two ends of the glass mold, so the overall structure is very complicated, not only difficult to manufacture, but also easy to use and Maintenance is troublesome. In addition, the probability of failure is relatively high. Second, due to the lack of a reasonable mold lifting function, the operator's operation intensity is high due to the inconvenience of grasping and pinching each time the mold is loaded and unloaded.
