Description

Technical Field

[0001] This utility model relates to the field of wire EDM fixtures, and in particular to a convenient fixture for clamping holes and slots in wire EDM machining. Background Technology

[0002] Wire EDM, a precision machining process based on the principle of electrical discharge, requires the workpiece to be suspended and clamped on a worktable during the machining process to ensure machining accuracy and safety. However, clamping and positioning face many challenges when machining holes and grooves on smaller workpieces. Existing conventional clamping methods are complex to position for small workpieces, requiring a significant amount of time for repeated adjustments and calibrations, which severely reduces machining efficiency. To address this, we propose a convenient clamping fixture for wire EDM hole and groove machining. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a convenient clamping fixture for wire EDM machining of holes and slots.

[0004] The technical solution of this utility model is as follows: A convenient wire EDM machining hole and slot clamping fixture, comprising a lower fixed pressure plate, characterized in that: an upper pressure plate is provided above the lower fixed pressure plate, a U-shaped groove is provided at one end of both the lower fixed pressure plate and the upper pressure plate, a threaded hole is provided on the lower fixed pressure plate, a bolt hole is provided at the end of the upper pressure plate away from the U-shaped groove, a bolt is provided in the bolt hole, and a waist hole is provided on the upper pressure plate between the U-shaped groove and the bolt hole.

[0005] Preferably, the inner wall of the U-shaped groove is arc-shaped, and the upper pressure plate is Y-shaped.

[0006] Preferably, the lower fixed pressure plate and the upper pressure plate are separately arranged, and when the upper pressure plate is in the assembled state, the bottom of both ends of the top of the upper pressure plate is in contact with the upper side of the workpiece.

[0007] Preferably, the mounting end of the bolt is installed corresponding to the bolt hole.

[0008] Preferably, the threaded hole and the waist hole are positioned corresponding to each other.

[0009] Compared with the prior art, the present invention has the following beneficial technical effects:

[0010] This utility model has a simple overall structure, is easy to use, and provides fast and accurate positioning. The workpiece is fixed by the two arms of the pressure plate, so that the reference surface of the workpiece is in contact with the base surface of the fixture. The workpiece is accurately positioned and has good stability, which greatly improves the processing efficiency. The separate design of the lower and upper pressure plates allows the device to process a large range. By adjusting the size of the fixture, holes and grooves of different sizes can be processed.

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Example

[0017] like Figure 1-3 As shown, this utility model proposes a convenient wire EDM machining hole and groove clamping fixture, including a lower fixed pressure plate 1 and an upper pressure plate 2 above the lower fixed pressure plate 1. The lower fixed pressure plate 1 and the upper pressure plate 2 are set separately. When the upper pressure plate 2 is in the assembled state, the bottom of the top two ends are in contact with the upper side of the workpiece. A U-shaped groove 3 is opened at one end of both the lower fixed pressure plate 1 and the upper pressure plate 2. The inner wall of the U-shaped groove 3 is set in an arc shape. The U-shaped groove 3 facilitates the operator to quickly perform hole and groove machining operations on the workpiece. The upper pressure plate 2 is set in a "Y" shape. The "Y" shape of the upper pressure plate 2 can fix the workpiece through the top two ends, so that the reference surface of the workpiece is in contact with the base surface of the fixture. The workpiece is accurately positioned and has good stability, which greatly improves the machining efficiency. The separate setting of the lower fixed pressure plate 1 and the upper pressure plate 2 makes the machining range of this device large. By adjusting the size of the upper pressure plate 2, holes and grooves of different sizes can be machined.

[0018] The lower fixed pressure plate 1 has a threaded hole 4, and the upper pressure plate 2 has a bolt hole 5 at the end away from the U-shaped groove 3. A bolt 6 is installed in the bolt hole 5, and the mounting end of the bolt 6 is installed corresponding to the bolt hole 5. The top of the bolt 6 is threaded and the bolt 6 is threaded to the bolt hole 5. When the bolt 6 and the bolt hole 5 are assembled, they act as a pad, which can improve the stability of the workpiece during the hole and groove processing operation and can also be used to position the workpiece when it is clamped. The upper pressure plate 2 has a waist hole 7 between the U-shaped groove 3 and the bolt hole 5. The threaded hole 4 and the waist hole 7 are positioned to correspond to each other. The waist hole 7 makes it easy for the operator to adjust the upper pressure plate 2 back and forth, which makes the empty groove processing operation more convenient. The overall structure of this device is simple, easy to use, and provides fast and accurate positioning.

[0019] In this embodiment, the operator first fixes the lower fixed pressure plate 1 above the wire cutting workbench, then places the workpiece to be processed on the upper side of the lower fixed pressure plate 1, and then aligns the bottom of the upper pressure plate 2 with the upper side of the workpiece. At this time, the waist hole 7 and the threaded hole 4 are in corresponding positions. Finally, the operator installs the bolt 6 in the bolt hole 5. The lower fixed pressure plate 1 and the upper pressure plate 2 firmly clamp the workpiece, so that the workpiece can be processed for holes and grooves.

[0020] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
