Abstract

The invention discloses a thread adjusting clamp. The thread adjusting clamp comprises a screw rod (2) and a limiting rod (4) and is characterized in that an internal thread section A (5), an internal thread section B (6) and a through hole (7) are arranged in the limiting rod (4) in sequence, the internal thread section A (5) is matched with an external thread of the screw rod (2), and the diameter of the internal thread section B (6) is equal to the size of a screw needing to be installed; the sum of the length of the internal thread section B (6) and the length of the through hole (7) is equal to the length of an exposed part of the screw needing to be installed; the diameter of the internal thread section A (5) and the diameter of the through hole (7) are larger than the diameter of the internal thread section B (6). According to a screw installation method to which the thread adjusting clamp is applied, the screw can be installed in place at a time, the size and length of the exposed part of the screw are guaranteed, adjustment is not needed, use is convenient, short time is consumed, and the percent of pass is high.

Description

technical field [0001] The invention belongs to the field of machining technology, and in particular relates to a thread adjusting fixture and a screw installation method. Background technique [0002] Screw connection is suitable for the connection between parts with little force. When assembling, the upper part is drilled into a through hole, and its diameter is slightly larger than the major diameter of the screw, and the other part is processed into a threaded hole, and then the screw is screwed in, and the connected part is pressed with the screw head. The threaded part of the screw must have a certain length to ensure the reliability of the connection. In the prior art, many parts mounting screws (see image 3 ), there are requirements for the length of the exposed part of the screw. The original installation method is to wrap the rubber with a clamp to rotate the screw, and then use a caliper to measure the exposed size. If it is unqualified, rotate it again until th...
