Abstract
The invention discloses a detecting tool for a lug of an oil cylinder, which is used for detecting the symmetry of the lug of the oil cylinder. An end surface and an internal thread of the lug are arranged on the right part of the lug, and a flat tongue surface is arranged on the left part of the lug. The detecting tool comprises a cushion block, a pressing block and a detecting sample pillar, wherein an external thread is screwed at the left part of the detecting sample pillar, a leveling step is arranged on the middle part of the detecting sample pillar, a measuring pillar is arranged on the right part of the detecting sample pillar, the screwed external thread is matched with the internal thread, the leveling step is matched with the end surface, and the measuring pillar is matched with the flat tongue surface. The detecting tool for the lug of the oil cylinder has the advantages that the structure is simple, and the construction cost is low.
Description
Technical field
The present invention relates to the frock technical field, especially relate to a kind of oil cylinder and detect frock.
Background technology
Hydraulic jack is the critical piece of engineering machinery, and earrings is one of chief component part of hydraulic jack, and its form and position tolerance accuracy requirement is high.And, along with market demands improve constantly, also more and more higher to the oil cylinder accuracy requirement.Wherein, the oil cylinder symmetry is important mass parameter, in case the earrings symmetry is lower, very easily cause the stressed deflection of piston rod in then using, seal is monolateral stressed, affects sealing part abrasion or damages seal, cause the oil cylinder leakage of oil, shorten the serviceable life of oil cylinder.Therefore, the equipment requirement that carries out the detection of earrings symmetry is high, involves great expense, and has directly raised the earrings preparation cost.
Summary of the invention
The purpose of this invention is to provide a kind of oil cylinder and detect frock, it has simple in structure, the characteristics that cost is lower.
To achieve these goals, the technical solution adopted in the present invention is: oil cylinder detects frock, symmetry for detection of oil cylinder, this earrings right part is provided with end face and earrings internal thread, the left part of earrings is provided with flat lingual surface, and described oil cylinder detects frock and comprises cushion block, briquetting and detection sample post, wherein, detect sample post left part and be provided with and screw in that external thread, middle part are provided with the step of keeping tie, right part is provided with measurement column, and screw in external thread and earrings internal thread match, keep tie step and end face and match.
Described measurement column and flat lingual surface match.
The present invention is compared with existing technology the advantage that has: 1, simple in structure, cost is lower.Oil cylinder symmetry of the present invention detects frock connects measurement by detecting the sample intercolumniation mode, realizes the detection to the earrings symmetry, and used unit quantity is few, and comparatively common, thereby comparatively simple, and cost is extremely low.2, save proving time, increase work efficiency.When adopting oil cylinder symmetry detection frock of the present invention to detect, the reviewer institute amount of working is less, and is easy to realize, technical ability without specific (special) requirements, is only needed about 3 minutes thereby detect an earrings part, and work efficiency can improve more than 10 times.3, promotional value is larger.For the parts that are similar to the oil cylinder structure, all can detect frock by oil cylinder symmetry of the present invention and detect, versatility is higher, has great promotional value.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is that the master of oil cylinder of the present invention looks the sectional structure synoptic diagram;
Fig. 2 is the main TV structure synoptic diagram of detection sample post of the present invention;
Fig. 3 is the structural representation of the use state of embodiments of the invention.
Among the figure: 10, flat board; 20, detect the sample post, 21, screw in external thread, 22, the step of keeping tie, 23, measurement column; 30, cushion block; 40, briquetting; 50, earrings, 51, the earrings internal thread, 52, end face, 53, flat lingual surface; 60, dial gauge, 61, gauge head.
Embodiment
The following stated only is preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, as shown in Figure 1: general, hydraulic jack earrings 50 right parts are provided with end face 52 and earrings internal thread 51, and end face 52 is vertical with the axis of earrings internal thread 51.Simultaneously, the left part of earrings 50 is provided with flat lingual surface 53.
See Fig. 2 and shown in Figure 3: oil cylinder detects frock, for detection of the symmetry of oil cylinder 50.This oil cylinder detects frock and comprises cushion block 30, briquetting 40 and detect sample post 20.Wherein, detecting sample post 20 left parts is provided with and screws in that external thread 21, middle part are provided with the step 22 of keeping tie, right part is provided with measurement column 23.And, screw in external thread 21 and earrings internal thread 51 match, keep tie step 22 and end face 52 and match.That is, screw in external thread 21 and can screw in the earrings internal thread 51, the left side of the step 22 of keeping tie and end face 52 close contacts, thus it is vertical with end face 52 to keep screwing in external thread 21.Optimize, in order to detect simultaneously the size of flat lingual surface 53, measurement column 23 and flat lingual surface 53 match.That is, thickness and the tolerance thereof of the diameter of measurement column 23 and tolerance thereof and flat lingual surface 53 are corresponding.
Using method of the present invention can be taked following steps:
When 1) detecting the earrings symmetry, carry out dull and stereotyped 10.Concrete, cushion block 30 is positioned on dull and stereotyped 10, and the measured surface of earrings 50 is placed on the cushion block 30, and the screw-in external thread 21 of check sample post 20 screws in the earrings internal threads 51, with briquetting 40 be pressed in earrings 50 above.Then, use the peak of the gauge head 61 contact measurement posts 23 of dial gauge 60, write down dial gauge 60 expression value A.
2) with earrings 50 upset 180o, use same briquetting 40 be pressed in earrings 50 above, use again the peak of the gauge head 61 contact measurement posts 23 of dial gauge 60, write down dial gauge 60 expression value B, then symmetry error is: (the ÷ 2 of A-B).
3) with same detection method, the symmetry error that poor half of full-scale reading is this part is got in the several transverse section of many measurements vertically.
Because the diameter of measurement column 23 and thickness and the tolerance thereof of tolerance and flat lingual surface 53 thereof are corresponding, then when detecting symmetry, also controlled the size of flat lingual surface 53.That is, once can detect two sizes.
