Description

Broadcast transmitter accessory machine adds positioning fixture Technical Field The application belongs to the technical field of positioning fixtures, and particularly relates to a broadcast transmitter accessory machining positioning fixture. Background The broadcast transmitter is used as a key infrastructure in the international communication field, and has irreplaceable strategic value in special scenes such as remote areas, marine environments, military, disaster relief and the like. The broadcasting transmitter manufacturing enterprises are required to construct core competitiveness through ways of improving equipment performance, reducing manufacturing cost, optimizing production process and the like. Among them, the processing technology of high-precision red copper parts has become one of the core bottlenecks restricting the industrial upgrade. Red copper materials are widely used for manufacturing key parts of broadcast transmitters due to excellent conductivity and ductility, but the characteristics of softer materials and easy deformation place severe demands on precision machining. In the traditional processing technology, in order to avoid surface damage caused by direct clamping of a vice, an operator usually adopts soft cloth to wrap a workpiece for protective clamping, and the operator relies on manual fine adjustment to realize positioning. However, this process has the following significant technical drawbacks: The prior art buffers clamping force through soft cloth to prevent red copper surface scratch, but the deformation characteristic of soft material leads to clamping force to be difficult to accurately control. In actual operation, operators need to perform empirical balance between 'preventing surface damage' and 'ensuring processing stability', if the clamping force is insufficient, processing vibration is easy to cause workpiece displacement, so that dimension is out of tolerance and even the cutter is broken, and if the clamping force is excessive, local stress concentration is possibly caused by uneven thickness of soft cloth, so that the surface of the workpiece is sunken or deformed. The manual clamping mode lacks a standardized positioning reference, and the workpiece position clamped each time has random deviation. During precision machining, small positioning errors accumulate over multiple processes, which can lead to fluctuations in critical dimensions (e.g., flatness, etc.) of the finished product out of tolerance. According to industry statistics, the processing qualification rate of similar parts in the traditional process is less than 70%, and the quality control cost is obviously increased. The soft cloth fiber is easy to be involved under the action of the high-speed rotary cutter, the cutter is damaged when the soft cloth fiber is light, and the risk of the operator involved when the soft cloth fiber is heavy is caused. Statistical data show that the personal injury accident rate caused by the process reaches 0.35%, and the industrial safety problem is formed. In order to solve the technical contradiction, the prior art attempts to improve by improving the soft cloth material, optimizing the manual operation standard and the like, but the inherent contradiction among the flexible protection, rigid positioning and safe processing is not broken through all the time. Therefore, developing a red copper part processing technology which takes surface protection, clamping precision and operation safety into consideration has become a technical problem to be broken through in the field of broadcast transmitter manufacturing. Disclosure of utility model The application aims to provide a broadcasting transmitter accessory machine positioning fixture, which solves the problems of clamping and positioning and the like in the processing of a frequency modulation terminal in a broadcasting machine, ensures the consistency of workpieces while ensuring the processing precision, and increases the survival rate and the processing efficiency of the workpieces.
