Description

Technical Field

[0001] This utility model relates to the field of machine tool components, specifically to a machining fixture for a high-pressure spring mechanism connector. Background Technology

[0002] High-voltage spring mechanism connectors are mainly used in high-voltage switchgear, such as high-voltage circuit breakers and load switches, in substations and distribution rooms of power systems to ensure the reliable operation of high-voltage electrical equipment. In the high-voltage spring mechanism, the spring stores energy and then releases it. The connector is responsible for accurately transmitting the spring's extension and contraction force to relevant components, such as the contact system, to achieve opening and closing operations. Figure 6 As shown, the existing high-pressure spring mechanism connector 23 has an irregular shape. Its bottom is provided with a recessed groove 24, a locking hole 25 communicating with the recessed groove 24, and a connecting platform 26 located on one side of the recessed groove 24. The connecting platform 26 is vertically connected. Due to the irregular shape of the high-pressure spring mechanism connector 23, it is processed using a CNC five-axis machining center to process its outer surface, groove, through hole, etc. However, during processing, the high-pressure spring mechanism connector 23 to be processed cannot be directly locked onto the turntable 27 of the CNC five-axis machining center. Therefore, for the processing of the existing high-pressure spring mechanism connector 23, a special tooling needs to be designed to ensure that it can be well fixed to the turntable 27 of the CNC five-axis machining center.

The top surface of the top plate 3 is provided with a first boss 4 and a second boss 5. The first boss 4 is located in a recessed groove 24 of the high-pressure spring mechanism connector 23, and the second boss 5 is located in a connecting platform 26 of the high-pressure spring mechanism connector 23. The top plate 3 is provided with a first bolt hole 6 that penetrates the top plate 3 and the first boss 4. A first bolt 7 that is threadedly connected to a locking hole 25 passes through the first bolt hole 6. The base plate 1 is locked onto the turntable 27 of a CNC five-axis machining center.

[0022] Reference Figure 1 and Figure 4 The base plate 1 has vertically extending slots 8 on both its left and right ends. A second bolt 9 passes through these slots and is threaded onto the turntable 27 of the CNC five-axis machining center. A washer 10 is placed between the head of the slot and the second bolt 9, through which the second bolt 9 passes. The slots 8 facilitate the adjustment of the second bolt 9's position, preventing positional deviations when the second bolt 9 is connected to the turntable 27 of the CNC five-axis machining center.

[0023] Reference Figures 1 to 3 The base plate 1 is connected to the support plate 2 by a third bolt 11, and the support plate 2 is connected to the top plate 3 by a fourth bolt 12. Specifically, the bottom surface of the support plate 2 is provided with a first threaded hole 13 and a second threaded hole 14, and the top surface of the support plate 2 is provided with a third threaded hole 15 and a fourth threaded hole 16. The base plate 1 is provided with a second bolt hole 17 and a first positioning hole 18. The third bolt 11 passes through the second bolt hole 17 and is threadedly connected to the first threaded hole 13.

The second positioning rod 22 is used to position the support plate 2 before locking the top plate 3 to prevent rotational displacement during locking.

[0026] Reference Figure 1 , Figures 4 to 6 The working principle of this utility model is as follows: First, the base plate 1 of the machining fixture is locked onto the turntable 27 of the CNC five-axis machining center. Then, the high-pressure spring mechanism connector 23 is placed on the top surface of the top plate 3, with the first boss 4 located in the recessed groove 24 of the high-pressure spring mechanism connector 23 and the second boss 5 located in the connecting platform 26 of the high-pressure spring mechanism connector 23. Next, the first bolt 7 passes through the first bolt hole 6 from the bottom surface of the top plate 3 and is threaded into the locking hole 25 of the high-pressure spring mechanism connector 23, thereby locking the high-pressure spring mechanism connector 23 onto the top plate 3. This machining fixture allows the high-pressure spring mechanism connector to be fixed on the turntable 27 of the CNC five-axis machining center, ensuring that the high-pressure spring mechanism connector can meet the machining requirements. After the high-pressure spring mechanism connector 23 is locked, its plane 28 is ensured to be perpendicular to the top surface of the top plate 3.
