Problems solved by technology

[0003] Aiming at the technical problem that the traditional method of fastening multiple screws requires two procedures to be repeated many times, resulting in a large amount of labor for workers and low work efficiency; the invention mainly provides a device for simultaneously installing and adjusting multiple screws, which can fasten Multiple screws only need to be operated once, and the screw tightening also limits its torque value

Embodiment Construction

[0011] The device in this embodiment is used to assemble 4 screws for fixing the circuit board at the same time. It has the same structure as the device described in the summary of the invention. In order to avoid repetition, only the key technical data are listed, including 4 screw wrenches (11), torque Adjust from 0.2N·M to 2N·M, and the screw that fixes the circuit board requires a torque of 1.2N·M.

[0012] Working principle: adjust the torque adjustment knob (34) to 1.2N·M, align the screw wrench (11) with the screw, the power input device (5) drives the driving gear (23) to rotate and drive the screw wrench (11) to rotate and tighten through the gear meshing. When the torque of the tightened screw reaches 1.2N·M, due to the special structure of the ratchet (131) and the ratchet (211) engaging with each other, the driven gear (21) will rotate along the guide rod (13) slide backward, the screw wrench (11) will no longer have torque output, which can prevent damage to the s...

Abstract

Aiming at the technical problem of the traditional method of low working efficiency in fastening multiple screws, the invention mainly provides a device capable of simultaneously mounting and adjusting multiple screws and belongs to the technical field of mechanical assembly. With addition of multiple screw wrenches on a working mechanism of the device, multiple screws can be fastened by one operation only; and also with design of a torque adjusting knob, torsion values of the screws can be limited when the screws are fastened. The device has the advantages that the torsion values of all the screws can be set rapidly, multiple screws can be fastened or loosened by rotating one driving gear only, the fastening procedure can be simplified, the labor quantity of a worker is reduced, the working efficiency is improved, and the device is particularly suitable for being applied to places in which multiple screws are fixed and improves the production efficiency.

Description

technical field [0001] The invention relates to a multi-screw simultaneous adjustment and fastening device, which belongs to the technical field of mechanical assembly. Background technique [0002] With the development of the manufacturing industry, during the assembly or installation of many equipment or precision instruments, multiple screws need to be tightened, adjusted at the same time, and advance and retreat together. For example, for precision optical instruments, the accumulation of some processing errors makes it impossible to meet the design accuracy requirements after assembly. Finally, all screws need to advance and retreat at the same time to adjust to the optimal position required by the optics. Another example is a car wheel with multiple screws that need to be tightened at the same time. The traditional method first installs four screws on the wheel with a small torque, and then tightens the screws one by one with a torque wrench with a fixed torque. The wh...
