Abstract

The utility model belongs to the technical field of detection, and provides a detection tool of a V-shaped groove of an axle box pull rod of a truck frame. The detection tool of the V-shaped groove of the axle box pull rod of the truck frame comprises a detection sample plate (1) and a calibration sample plate. The detection sample plate (1) used for detecting that whether the V-shaped groove meets a standard or not comprises a cross plate (3) and a vertical plate (4). The vertical plate (4) is arranged below the middle portion of the cross plate (3), and the vertical plate (4) is of a structure matched with the structure of the V-shaped groove of an axle box pull rod seat (2) and with a reducing diameter from top to bottom. The lower end surface of the vertical plate (4) is a plane, and the lower end of the vertical plate (4) is of an inclined transition structure. The calibration sample plate used for calibrating the detection sample plate (1) is of a vertical plate structure. A groove matched with the vertical plate of the detection sample plate is formed in the calibration sample plate. The detection tool of the V-shaped groove of the axle box pull rod of the truck frame achieves the fast detection of the V-shaped groove, and is accurate and reliable in measured result. In addition, the detection tool of the V-shaped groove of the axle box pull rod of the truck frame has the advantages of being simple in structure and good in durability.

Description

The detection frock of bogie frame axlebox rod V-type groove

Technical field

The utility model belongs to the detection technique field, relates generally to a kind of detection frock of bogie frame axlebox rod seat V-type groove.

Background technology

In bogie frame processing and manufacturing process, axlebox rod seat V-type groove is one of processing difficulties, is mainly because its inwall is the dip plane of gradient 1:10, and its central diameter tolerance comparatively strict (being generally 0.2mm).The processing V-shaped groove mainly relies on special-purpose profile milling cutter, but whether qualified difficult detection of the V-type groove after machining, traditional detection method is that line detects, namely according to the figure paper size, the required size line is marked, detect with survey instruments such as vernier calipers, this detection means is rule first and is had error again, second can only detect size numerical value and can not detect its form tolerance, follow-up assembling is not had practical significance, and efficient is not high.Therefore the check of V-type groove should design and produce the dedicated test model, and the V-type groove after guaranteeing to process satisfies follow-up matching requirements.

The utility model content

For solving the problems of the technologies described above, the purpose of this utility model is the detection frock that proposes a kind of bogie frame axlebox rod seat V-type groove.

The utility model is completed above-mentioned purpose and is adopted following technical scheme:

A kind of detection frock of bogie frame axlebox rod seat V-type groove, described detection frock comprise detection model and calibration model; Whether standard compliant detection model includes transverse slat and riser in order to detect the V-type groove; Described riser is positioned at the below at transverse slat middle part, described riser for join with the structure kissing of axlebox rod seat V-type groove, the structure in convergent footpath from top to bottom; The lower surface of described riser is the plane, and the lower end of described riser is the structure of chamfered transition; The calibration model that detects model in order to calibration is the riser structure; Has the groove that coordinates in order to the riser that detects model on described calibration model.

Described V-type groove detects frock and coordinates clearance gauge to use, the utility model in use, the described riser that detects model is inserted in axlebox rod seat V-type groove, can detect bottom gap and the side clearance of axlebox rod seat V-type groove with the clearance gauge stack of different size, as long as acquired results meets standard-required and just can judge that it is qualified, simple and practical, convenient and reliable.

The detection frock of a kind of bogie frame axlebox rod seat V-type groove that the utility model proposes has realized the quick test of V-type groove, and measurement result accurately, reliably; In addition, the utility model also has simple in structure, the characteristics that durability is good.

Embodiment

By reference to the accompanying drawings embodiment of the present utility model is illustrated:

As shown in Figure 1 and Figure 2, a kind of detection frock of bogie frame axlebox rod seat V-type groove, described detection frock comprise detection model 1 and calibration model; Whether standard compliant detection model 1 includes transverse slat 3 and riser 4 in order to detect the V-type groove; Described riser 4 is positioned at the below at transverse slat 3 middle parts, described riser 4 for join with the structure kissing of axlebox rod seat 2V type groove, the structure in convergent footpath from top to bottom; The lower surface of described riser 4 is the plane, and the lower end of described riser 4 is the structure of chamfered transition; The calibration model that detects model 1 in order to calibration is the riser structure; Has the groove that coordinates in order to the riser that detects model on described calibration model.

In conjunction with Fig. 3, described V-type groove detects frock and coordinates clearance gauge to use, the utility model in use, the described riser that detects model is inserted in axlebox rod seat V-type groove, can detect bottom gap and the side clearance of axlebox rod seat V-type groove with the clearance gauge stack of different size, as long as acquired results meets standard-required and just can judge that it is qualified, and is simple and practical, convenient and reliable.
