Description

TECHNICAL FIELD

[0001] The utility model relates to a spark machine, especially a spark machine with a protection structure. BACKGROUND

[0002] The spark machine is a machine tool for metal processing by using the principle of electric spark discharge. The tool electrode and the workpiece are connected to two poles of the pulse power source respectively and are immersed in the working liquid. The tool electrode is fed to the workpiece by the gap automatic control system. When the gap between the two electrodes reaches a certain distance, the pulse voltage applied to the two electrodes will break through the working liquid, resulting in spark discharge, thereby etching off the metal material on the workpiece.

[0003] The working process of the spark machine involves high-temperature discharge phenomenon. The temperature in the working area is extremely high. If it is accidentally touched, it may cause burns or other injuries. In actual application, the spark machine is usually equipped with a protection device to ensure safety. Most of the existing protection door switches need to be manually operated, which not only increases the operation complexity, but also may increase the safety hazard due to misoperation. SUMMARY

DETAILED DESCRIPTION

[0019] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0020] A spark dynamometer with a protective structure, such as Figures 1-5 As shown, the device includes a main body 1, a head 2, an electric slide rail 3, a first protective plate 4, a pusher 41, a second protective plate 5, and guide rods 6. The head 2 is mounted on the main body 1. The front of the main body 1 is lower than its left and right sides. The lower part of the main body 1 is the working area. Storage slots are opened on the front and left and right sides. Electric slide rails 3 are symmetrically installed on the left and right sides of the storage slots. The first protective plate 4 is slidably connected in the storage slots. The pusher 41 is located on the left and right sides of the first protective plate 4. The two electric slide rails 3 are slidably connected to the pusher 41 on the left and right sides of the first protective plate 4, respectively. The second protective plate 5 is slidably connected in the storage slots. The lower part of the left and right sides of the second protective plate 5 has a groove 51. Two guide rods 6 are connected between the upper and lower sides of the two grooves 51. The pusher 41 of the first protective plate 4 is slidably connected to the guide rods 6 on the left and right sides, respectively. The front and rear lengths of the pusher 41 are the same as those of the second protective plate 5. When the device stops working, both the first protective plate 4 and the second protective plate 5 are located in the storage slots.

[0021] When not in use, the first protective plate 4 and the second protective plate 5 are located in the storage slot.

After use, the electric slide rail 3 drives the first protective plate 4 to move downward. The second protective plate 5 will move downward together with the first protective plate 4 due to its own weight and the supporting force of the pushing part 41. When the second protective plate 5 descends to the bottom, the second protective plate 5 is completely inserted into the storage slot. The first protective plate 4 continues to descend until the first protective plate 4 is completely inserted into the storage slot.
