Handheld operation controller of numerical control machine tool

[0014] A hand-held operation controller for a numerically controlled machine tool described in this embodiment is composed of a circuit board (1), an upper part (2) of the housing outside the circuit board (1) and a lower part (3) of the housing, and its features That is: the signal output end of the circuit board (1) is a socket terminal, which is a pin-shaped structure directly processed on the circuit board, and the connection between the upper part of the housing (2) and the lower part of the housing (3) The upper part of the housing (2) and the lower part of the housing (3) are connected by heat riveting, and the edge of the upper part of the housing (2) is closely matched with the edge of the lower part of the housing (3). There are 3 positioning columns on the lower part of the housing (3) to fix the circuit board.

[0015] The hand-held operation controller of the numerical control machine tool also includes an upper sheath of the signal output port socket, a lower sheath

[0019] A hand-held operation controller for a numerically controlled machine tool described in this embodiment is composed of a circuit board (1), an upper part (2) of the housing outside the circuit board (1) and a lower part (3) of the housing, and its features The reason is: the signal output end of the circuit board (1) is a columnar terminal, which is a columnar terminal structure directly processed on the circuit board, between the upper part of the housing (2) and the lower part of the housing (3). Connected by heat riveting, the upper part of the housing (2) and the lower part of the housing (3) are closely fitted with a spigot at the edge, and there are five positioning columns on the lower part of the housing (3) to fix the circuit board.
