Adjustable multi-axis automatic locking screw machine and its position adjustment method

Abstract

The invention discloses an adjustable multi-shaft automatic screwing machine and a position adjustment method thereof. The screwing machine comprises a machine frame, an object containing table, a portal frame, a plurality of screwing mechanisms, a position adjustment mechanism capable of adjusting movement of the screwing mechanisms in the X axis direction, a Z-axis movement mechanism capable of driving the screwing mechanisms to vertically move, a Y-axis movement mechanism capable of driving the object containing table or the screwing mechanisms to move and a control mechanism. The position adjustment mechanism comprises a nut-rotating-type lead screw pair fixed to the portal frame. A plurality of nuts are arranged on the nut-rotating-type lead screw pair according to the number of the screwing mechanisms. Each nut is provided with an X-axis nut base which is fixedly linked with the corresponding screwing mechanism. Each screwing mechanism is provided with an X-axis motor to be connected with the corresponding nut in a transmission manner through a transmission mechanism. According to the adjustable multi-shaft automatic screwing machine and the position adjustment method, the relative positions among the screwing mechanisms can be adjusted to adapt to screw hole positions in a to-be-screwed workpiece, and therefore the multiple screw hole positions in a row in the workpiece can be screwed at the same time.

Description

technical field

[0001] The invention relates to the field of screw locking equipment, in particular to an adjustable multi-axis automatic screw locking machine and a position adjustment method thereof. Background technique

[0002] Due to the large size and model of flat-panel TVs and the large area of ​​the back panel, the screws that need to be locked are short in length, large in diameter and large in number, and are arranged in a matrix. At present, in the production process, the locking of the screws is mainly done manually. Completion, low efficiency and poor stability. Existing adjustable screw locking machines often only have a single locking screw mechanism, and for multiple locking screw mechanisms, the distance between the electric screwdrivers is often not adjustable, and the flexibility is poor. For some equipment that can adjust the distance between electric batches, it is often a mechanical adjustment, with a low degree of automation and a long adjustment tim...
