Therefore, it is necessary to manually arrange the milling machine to unload and the EDM machine to load. The process is complicated, which increases the time for unloading and manual secondary loading. There is room for further simplification. Moreover, after loading, the EDM machining must first take the number of points to ensure the positioning accuracy. This makes it easy to make mistakes in taking the number, which increases the error of human operation. The machining accuracy still has room for further improvement. Therefore, an electric milling machine is proposed to solve the above problems. Utility Model Content

[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] See also Figure 1-2 An electric milling machine in the present application includes a body 1, a workbench 11 is arranged on the body 1, and a machine head is provided with a three-axial transmission through a transmission mechanism, the body 1 is placed on the workbench 11 to process a workpiece, the transmission mechanism includes a three-axial slide rail, and a slide is provided in the slide rail for corresponding sliding, the machine head includes a milling head 4 and a discharge head 5, the milling head 4 and the discharge head 5 are slidably arranged in the same slide rail through the same slide, and the machine head acting on the workbench 11 is switched by sliding.

[0015] The electric milling machine is a machine type composed of two processing modes, CNC milling head and CNC discharge forming. The device slides the milling head 4 and the discharge head 5 through the same slide and is arranged in the same slide rail, so that different head positions can be switched through the sliding of the transmission mechanism, and the discharge processing can be directly performed after the CNC milling processing is completed, so that the two heads share the same data and the same workbench 11;

[0016] After CNC milling is completed, the EDM is directly carried out. The two heads share the same data and the same workbench 11, which can directly switch to the next process of EDM, reduce the management work such as process standby and production scheduling, and save the time of manual unloading and secondary loading;

[0017] Moreover, when loading the workpiece from the milling machine to the EDM machine, in order to ensure the positioning accuracy and processing accuracy, the workpiece needs to be calibrated first, the data is taken from the center, the center needs to be re-found, and then the X, Y edge reference and Z axis data are added. Manual workpiece electrode calibration and manual input of processing values ​​often lead to human errors in data acquisition;

[0018] Therefore, the device does not require secondary loading, avoids errors caused by clamping, reduces human operation errors, and shares the same data and the same workbench 11 to ensure the consistency of the workpiece benchmark during CNC milling and discharge machining. In addition, the double heads on the same slide ensure the consistency of the center and improve the machining accuracy.

[0019] The device is equipped with a transmission mechanism to drive the machine head to move in the x, y, and z axes to achieve processing of the workpiece in three directions. The three-axial transmission mechanism is a prior art and a conventional design in the field, including but not limited to the contents disclosed in the Chinese patent publication number CN205702586U, and is not an innovative invention of the present application and will not be described in detail here.

[0020] Furthermore, the transmission mechanism also includes a lifting assembly, a longitudinal slide rail is provided on the upper end surface of the body 1, a slide 2 is slidably provided in the longitudinal slide rail, a transverse slide rail 21 is fixed to the slide 2, a slide 2 3 is slidably provided in the transverse slide rail 21, and a milling head 4 and a discharge head 5 are provided on the slide 2 3 through different lifting assemblies.

[0021] The device sets two different machine heads on the slide 2 3 in the transverse slide rail 21, so that after completing the previous process, the device can switch the machine head acting on the workbench 11 by adjusting the slide 2 3 left and right. The machine head not involved in the processing is raised and stored by the lifting assembly, making the device easy to adjust.

[0022] Furthermore, a blocking block is provided at one end of the longitudinal slide rail away from the machine head.

[0023] The device sets a stop block at one end of the longitudinal slide rail so that when the slide 2 reaches the limit position, it abuts against the stop block to prevent it from continuing to move out of the slide rail.

[0024] Furthermore, a plurality of positioning holes are provided on the slide rail.

[0025] The device can install the guide rail more accurately by arranging a plurality of positioning holes on the slide rail, thereby ensuring the accuracy of the relative positions of the guide rails with respect to the base surface.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
