Description

Technical Field

[0001] This utility model relates to the field of electrical discharge machining equipment, and in particular to an electrical discharge machining extension frame. Background Technology

[0002] Electrical discharge machining (EDM) is a special machining method that removes material using the electro-erosion phenomenon. Its core principle is to generate instantaneous high temperatures through pulsed spark discharge between the tool electrode and the workpiece electrode, melting or vaporizing the material and thus machining the workpiece. In existing EDM equipment, the workpiece is placed on the machine platform below the tool electrode for EDM. However, when the workpiece is a long cylindrical structure and its interior needs to be machined, the shortcomings of existing EDM equipment become apparent. First, the space between the tool electrode clamping mechanism and the platform is limited, thus limiting the length of the tool electrode that can be clamped. Second, even if there is sufficient space to install the tool electrode, it is difficult to fit a long cylindrical workpiece over the tool electrode. Therefore, existing EDM equipment is fundamentally inadequate for machining the interior of long cylindrical workpieces. Thus, it is necessary to develop an EDM extension frame to address these problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1 to 3 As shown, an electrical discharge machining (EDM) extension frame includes a placement platform 01, a machine tool chuck 02, a first clamping block 03, a vertical mounting rod 04, a second clamping block 05, a horizontal mounting rod 06, a third clamping block 07, an electrode chuck 08, and a tool electrode 09. The placement platform 01 is fixed to the equipment platform. The upper end of the machine tool chuck 02 is fixed to the equipment. One end of the first clamping block 03 is fixed to the machine tool chuck 02 and its height and angle are adjustable. The lower end of the vertical mounting rod 04 is fixed to the other end of the first clamping block 03.

The electrode chuck 08 is fixed to the other end of the third clamping block 07. The tool electrode 09 is positioned above the placement platform 01 and one end is fixed to the electrode chuck 08.

[0023] The vertical mounting rod 04 is adjusted to a suitable position within the equipment via the first clamping block 03. The horizontal mounting rod 06 is adjusted to a suitable height and angle via the second clamping block 05, thereby placing the horizontal mounting rod 06 in a relatively ample space above the equipment.

The advantage of this design is that the tool electrode 09 can be extended from the machine tool shank 02 through the extension frame, including vertical and horizontal extension, so that the tool electrode 09 can be located in the ample space above the equipment. The workpiece can be placed in the ample space above the equipment, thereby realizing electrical discharge machining on the inside of long cylindrical workpieces. The extension frame has a simple structure, is easy to operate, and can save the cost of purchasing large equipment.

[0024] The placement platform 01 includes a first pad 011, a second pad 012, a base plate 013, and a V-shaped plate 014.

[0027] After adjusting the position of the vertical mounting rod 04 relative to the machine tool chuck 02, tighten the first bolt 033 to clamp and fix the machine tool chuck 02 and the vertical mounting rod 04 with the first jaw 031.

[0028] The second clamping block 05 has two sets of second clamping jaws 051 at each end. The second clamping block 05 also has a second vertical circular hole 052 and a second horizontal circular hole 053 at each end. The gap between the second vertical circular hole 052 and the two sets of second clamping jaws 051 is connected. The gap between the second horizontal circular hole 053 and the other two sets of second clamping jaws 051 is connected. The vertical mounting rod 04 and the horizontal mounting rod 06 correspond to the second vertical circular hole 052 and the second horizontal circular hole 053, respectively. The second clamping block 05 is also provided with a second bolt 054. The second bolt 054 passes through one set of second clamping jaws 051 and is threadedly connected to another set of second clamping jaws 051 at the same end.

[0029] After adjusting the position of the horizontal mounting rod 06 relative to the vertical mounting rod 04, tighten the second bolt 054 to clamp and fix the vertical mounting rod 04 and the horizontal mounting rod 06 with the second clamp 051.

[0030] The third clamping block 07 has two sets of third clamping claws 071 at each end. The end of the third clamping block 07 is also provided with a first horizontal circular hole 072. The gap between the first horizontal circular hole 072 and the two sets of third clamping claws 071 is connected. The horizontal mounting rod 06 and the electrode clamping handle 08 are respectively located in the two sets of first horizontal circular holes 072. The third clamping block 07 is also provided with a third bolt 073. The third bolt 073 passes through one set of third clamping claws 071 and is threadedly connected to another set of third clamping claws 071 at the same end.

[0031] After adjusting the position of the electrode clamp 08 relative to the horizontal mounting rod 06, tighten the third bolt 073 to clamp and fix the horizontal mounting rod 06 and the electrode clamp 08 with the third jaw 071.

[0032] The first clamping block 03, the second clamping block 05 and the third clamping block 07 are each provided with multiple sets of weight reduction holes 10. The weight reduction holes 10 can reduce the weight of the first clamping block 03, the second clamping block 05 and the third clamping block 07, making it easier for operators to install and adjust.

[0033] This design also includes a flow guiding assembly 11, which includes a flow guiding housing 111, a liquid inlet 112, a liquid outlet 113, and a water inlet pipe 114. One side of the flow guiding housing 111 is provided with an insertion hole 1111 for fitting onto the end of the workpiece. The flow guiding housing 111 is provided with a flow guiding cavity. The liquid inlet 112 and the liquid outlet 113 are respectively fixed at the upper and lower ends of the flow guiding housing 111. Both the liquid inlet 112 and the liquid outlet 113 are connected to the flow guiding cavity. One end of the water inlet pipe 114 passes through the liquid inlet 112 and is inserted into the workpiece.

[0034] The flow guiding component 11 is fitted onto the end of the workpiece away from the electrode holder 08 through the insertion hole 1111. During electrical discharge machining, the working fluid continuously flows into the workpiece through the water inlet pipe 114, carrying away the machining waste and flowing into the flow guiding cavity from the workpiece port. The working fluid in the flow guiding cavity flows out from the liquid outlet 113 and falls onto the equipment platform. If the liquid outlet 113 is not directly above the equipment platform, a water pipe can be connected to the liquid outlet 113 to guide the working fluid to the equipment platform for recycling.

[0035] The flow guide housing 111 is made of elastic material, which allows the insertion hole 1111 to expand and contract within a certain range, adapting to workpieces of different diameters for assembly.

[0036] The upper end of the material guide housing is provided with multiple sets of air inlets. When the insertion hole 1111 has a certain elasticity, the connection between the insertion hole 1111 and the workpiece will be sealed. Therefore, by providing multiple sets of air inlets, external air can enter the guide cavity, which is conducive to the working fluid being discharged from the liquid outlet 113.

[0037] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
