Technical Field
[0001] This utility model relates to the field of CNC machining technology, and in particular to a multi-station dual-workpiece machining fixture for bracket components. Background Technology
[0002] Support components are structural members used to support, position, and connect various parts. In mechanical systems, they primarily bear static or dynamic loads, maintain structural stability, and ensure the correct relative positions of components. Support components play a vital role in various industries, not only fulfilling the basic functions of mechanical structures but also continuously meeting increasingly stringent application requirements through material and process innovations. With the further application of new materials and technologies, the performance and application scope of support components will be further expanded.
[0003] The following problems exist in the current CNC machining process for bracket components: Each bracket component requires individual clamping, resulting in low machining efficiency and failing to meet the demands of mass production; the repeatability of component positioning accuracy is difficult to guarantee during multiple clamping processes, easily leading to accumulated machining errors and affecting product quality; operators need to frequently clamp and disassemble components, resulting in high labor intensity and fatigue; and the need to purchase multiple single-station fixtures, as well as frequent tool changes and equipment adjustments, leads to high production costs. Utility Model Content

The first station includes a first baffle fixed to the base plate and a first clamp for pressing a workpiece in a blank state against the first baffle. Two symmetrical first workpiece mounting positions are formed at the first station. The second station includes a second baffle fixed to the base plate and a second clamp for pressing a workpiece processed at the first station against the second baffle. Two symmetrical second workpiece mounting positions are formed at the second station. Two third stations are provided opposite each other.

7. The multi-station dual-workpiece machining fixture for bracket components as described in any one of claims 1-6, characterized in that, The first workstation is adjacent to the second workstation, and the first baffle in the first workstation that is closer to the second workstation and the second baffle in the second workstation that is closer to the first workstation are an integral structure.
8. The multi-station dual-workpiece machining fixture for bracket components as described in claim 7, characterized in that, Each of the third workstations is provided with two third pressure plates, which are detachably installed on the base plate by screws. When the workpiece is installed in the third workstation, the two third pressure plates press against the two corners on the diagonal of the workpiece's base plate. The fourth workstation is equipped with two fourth pressure plates, which are detachably installed on the base plate by screws. When the workpiece is installed in the fourth workstation, the two fourth pressure plates press against the two corners on the diagonal of the workpiece's base plate.
9. The multi-station dual-workpiece machining fixture for bracket components as described in claim 8, characterized in that, The two third workstations are arranged side by side. When the workpiece is installed in the third workstation, the width direction of the workpiece's base plate is the same as the arrangement direction of the two third workstations, and the two third pressure plates are respectively located on both sides of the length of the workpiece's base plate. The two fourth workstations are arranged side by side. When the workpiece is installed in the fourth workstation, the width direction of the workpiece's base plate is the same as the arrangement direction of the two fourth workstations, and the two fourth pressure plates are respectively located on both sides of the length of the workpiece's base plate.
10. The multi-station dual-workpiece machining fixture for bracket components as described in claim 9, characterized in that, Based on the fact that the first workstation and the second workstation are adjacent, the first workstation, the third workstation and the fourth workstation are arranged in sequence, the second workstation, the fifth workstation and the sixth workstation are arranged in sequence, the third workstation and the fifth workstation are directly opposite each other, and the fourth workstation and the sixth workstation are directly opposite each other.
