Description

TECHNICAL FIELD

[0001] The utility model belongs to pillow spring detection field, concretely relates to a steel tool tray structure matched with visual detection pillow spring. BACKGROUND

[0002] In the railway freight car repair work, especially in the pillow spring vision detection line application, often involves the situation of automatic equipment transporting pillow spring, mostly by placing pillow spring on tool tray, tool tray flows to the required station along the production line, and the pillow spring on the tool tray is recognized by vision to obtain the required parameters.

[0003] At present, the tool tray for placing pillow spring generally has two kinds:

[0004] One is PVC hard plate as tray bottom plate, and positioning cylinder is installed on the upper side, pillow spring is divided into large and small springs, small spring is inside large spring, both are placed in a positioning cylinder, and the positioning cylinder is slightly larger than the outer diameter of large spring. Nine groups of large and small springs are placed on one tray, and the tray flows on the production line to complete the transportation requirements of the rear station (one bogie generally has nine groups of large and small springs on the left and right, which is equivalent to two trays required for one bogie).

[0005] The tray needs to bear the spring weight of 125kg, and the weight of the tray itself is about 40kg, that is, the maximum weight of the whole tray is about 165kg. In actual use, it is found that due to the excessive load, the tray is easily deformed after being used for a period of time, which greatly affects the subsequent visual collection of pillow spring data, resulting in frequent replacement of the tray, which greatly troubles the user.

[0006] The other is a tray bottom plate made of aluminum plate, and positioning cylinder is provided on the upper side, and the edge is wrapped with other anti-collision materials to increase durability. At present, there are few such trays on the market, mainly due to the influence of the general rusty and harsh production environment of freight car repair production line, the wear of aluminum alloy is more serious, and the steel spring may fall on the tray, which will cause the aluminum alloy surface to be pitted, which will greatly affect the subsequent measurement of spring height and other stations taking the upper surface of the tray as the reference, resulting in inaccurate results, which also leads to frequent replacement of the tray.

[0007] In summary, the problems of the above two kinds of trays with different materials are as follows:

[0008] (1) The accuracy cannot be guaranteed. The independent positioning cylinders with bottom holes are installed on the bottom plate, and only the accuracy of the bottom thickness of the independent positioning cylinder can be guaranteed by machining, and the measurement accuracy of each positioning cylinder after installation cannot be guaranteed.

[0009] (2) weight is easy to further increase. The bolt used for positioning cylinder installation is installed from the upper part to the lower part, and a thick cylinder bottom is needed to ensure that the bolt head can be embedded in the cylinder bottom without affecting the placement of the steel spring and visual shooting collection, so that the overall weight is increased.

[0010] (3) PVC and aluminum alloy materials are easy to bend and deform under long-term load, resulting in low precision and short service life.

[0011] (4) The tray guiding performance is poor, which can cause large resistance to the guiding strips on both sides of the line body and poor flow.

[0012] (5) The bolt head on the upper surface of the tray leaks out, affecting visual collection. SUMMARY

[0016] Further, the bottom of the positioning cylinder is provided with a protruding limiting buckle which can be matched and inserted into the positioning groove of the upper top plate.

[0017] Further, the limiting buckle passes through the positioning groove and protrudes from the reverse side of the upper top plate and is fixed by using a tongue depressor and a bolt.

[0018] Further, the thickness of the lower bottom plate is 4-7mm, and the thickness of the upper top plate is 4-7mm.

[0019] Further, the lower bottom plate and the upper top plate are integrally milled to ensure precision.

[0020] Further, the lower bottom plate and the upper top plate are placed with a raised circular table and a pad strip and are welded together.

[0021] Further, the tool tray structure is wrapped with self-lubricating material.

[0022] Further, the tool tray structure is provided with anti-collision strips at the four corners.

And the relatively low price, good processing performance material, the steel material of the visual inspection pillow spring supporting use steel tool tray structure of the embodiment (specifically refers to the material of the upper top plate 2, the lower bottom plate 1 and the positioning cylinder 6 is preferably steel, such as steel Q235B, its yield strength reaches 235Mpa, surface hardness 180-220HB, its parameters are better than hard pvc material and aluminum alloy 6061, its market demand is large, the price is low, the processing performance is superior, the overall advantage is obvious. Then through the better structure design, weight reduction treatment can meet the requirements. Secondly, considering its guiding nature, the finished product is edge covered, and oil nylon is selected for edge covering (herein referred to as anti-collision strip 7), which has detachability and is convenient for subsequent wear regular replacement.

[0055] The above only describes the preferred embodiment of the present application, and does not constitute a limitation on the scope of protection of the present application.
