Problems solved by technology
[0003] At present, EDM deposition is completed by manual operation. Since the staff maintain a certain contact force based on feeling and experience during manual operation, it is difficult to ensure a consistent contact force between the electrode and the sample, which greatly reduces the deposition rate. efficiency and deposition quality

Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0025] Currently, EDM deposition is done manually, but for large parts, automated deposition must be used to ensure deposition quality. During the automatic deposition process, how to maintain a consistent contact force between the electrode and the sample is a key technical problem that must be solved in deposition automation. In addition, during the automatic deposition process of EDM, the electrode material is continuously consumed, and a gap is formed betw...

Abstract
The invention discloses an electrode position compensation device capable of achieving electric spark automatic deposition. The electrode position compensation device is characterized in that the driving output end of a driving mechanism of the device is fixedly connected with the transmission input part of a transmission mechanism, a fixing and supporting device is arranged at the transmission output part of the transmission mechanism, the driving mechanism drives the transmission mechanism to drive the fixing and supporting device to do linear motion downwards in the vertical direction, thefixed end of a constant force device is arranged on an upper supporting seat of a fixing support, the force output end of the constant force device is fixedly arranged on a transmission mechanism body, an electric spark deposition gun is installed on the fixing and supporting device, and the sum of the vertical upward pulling force provided by the constant force device for the transmission mechanism body and the supporting force generated when the electrode of the electric spark deposition gun are in contact with the surface of an object is equal to the sum of the sum of the gravity of the transmission mechanism, the gravity of the fixing and supporting device and the gravity of the electric spark deposition gun and the vertical downward pressure output by the driving output end when the driving mechanism is started. By the adoption of the electrode position compensation device, the position compensation of the deposition gun after electrode abrasion can be automatically realized, andthe deposition efficiency can be improved.
Description
technical field [0001] The invention relates to the technical field of electric spark deposition, in particular to an electrode position compensation device for electric spark automatic deposition. Background technique [0002] EDM technology is a process that directly uses the high-density energy of EDM to modify and strengthen the metal surface. Using EDM surface modification technology, a layer of amorphous alloy coating can be deposited on the surface of titanium alloy, which can significantly improve the flame retardancy and wear resistance of titanium alloy. The key to EDM is to control the contact pressure between the electrode and the workpiece. The contact force between the electrode and the sample determines the discharge gap and the discharge current, which directly affects the deposition efficiency and deposition quality. Therefore, the contact force between electrode and specimen must be consistent at all times. [0003] At present, EDM deposition is completed...
