Abstract
The utility model discloses a clamp dedicated for a high-speed bullet train door carrying frame. The clamp dedicated for the high-speed bullet train door carrying frame comprises a base board and is characterized in that a left fixing plate and a right fixing plate are respectively arranged at two ends of the base board. A positioning hole is arranged in the middle of the left fixing plate. Threaded positioning holes are distributed in the upper end face of the base board. A fixing plate is fixedly arranged at the rear end portion of the upper end face of the base board. The front end face of the fixing plate is clamped with a side of a to-be-machined high-speed bullet train door carrying frame. Two limiting pillars which protrude backwards and are matched with installation holes in the other side of the to-be-machined high-speed bullet train door carrying frame are arranged at the rear end face of the fixing plate. The clamp dedicated for the high-speed bullet train door carrying frame is reasonable in structural design and uniform in clamping and positioning benchmark and simplifies clamping procedures as clamping is done once, prevents deformation factors caused by multiple-time clamping, ensures that form and location tolerances of all machined parts and technical requirements are met as to-be-machined faces, holes and grooves of the parts are done once, improves working efficiency, ensures the percent of pass and improves reliability of installing a door of a bullet train.
Description
Technical field
The utility model relates to high speed motor car and takes door frame process equipment field, relates in particular to a kind of high speed motor car and takes the door frame special fixture.
Background technology
Traditional machining is carried out single operation station clamping processing, mill, the five processes processing such as brill, boring, in the clamping of five processes, every procedure will carefully be proofreaied and correct, per pass process operations personnel are required to have higher technical merit, and also can cause part to press-fit distortion through multiple clamping, increase time cost, and the form and position tolerance between uncontrollable each machined surface, the qualification rate of part can't guarantee.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, provide a kind of high speed motor car to take the door frame special fixture, its clamping positioning datum is unified, and disposable clamping has been simplified the clamping formality, prevent the deformation factor because of multiple clamping, once finish part face to be processed and hole and groove, guarantee each working position form and position tolerance and specification requirement, increase work efficiency, and the assurance qualification rate, improve the reliability of the car door installation of motor-car.
The utility model is achieved through the following technical solutions:
A kind of high speed motor car is taken the door frame special fixture, include base plate, it is characterized in that: the two ends of described base plate are respectively equipped with left and right fixed head, the middle part of described left fixed head is provided with locating hole, the upper surface of described base plate is distributed with the screw thread locating hole, the rearward end of described base plate upper surface is installed with fixed head, the front end face of described fixed head is taken door frame one side with high speed motor car to be processed and is engaged, and rear end face is provided with two and protrudes backward and take the limited post that door frame opposite side installing hole cooperates with high speed motor car to be processed.
The outside of described right fixed head is provided with draw-in groove.
The utility model is modular fixture, the pinpoint performance of combining with digital control lathe, carry out one side and three-point fix, multiple spot press-fits, its clamping positioning datum is unified, disposable clamping has been simplified the clamping formality, prevents the deformation factor because of multiple clamping, once finish part face to be processed and hole and groove, guarantee each working position form and position tolerance and specification requirement, increase work efficiency, and guarantee qualification rate, improve the reliability of the car door installation of motor-car, while anchor clamps good rigidly, operating technology requires simple, and machining accuracy reaches specification requirement.
The utility model has the advantages that:
The utility model reasonable in design, the clamping positioning datum is unified, disposable clamping, simplify the clamping formality, prevented the deformation factor because of multiple clamping, once finished part face to be processed and hole and groove, guarantee each working position form and position tolerance and specification requirement, increase work efficiency, and guarantee qualification rate, improve the reliability of the car door installation of motor-car.
