Abstract
The utility model discloses a tool for detecting the eccentricity of a link plate hole of a chain. The tool consists of a measuring scale and a U-shaped scale holder, wherein the measuring scale comprises a main scale, a spiral scale, a micrometric screw rod and a fine-tuning knob; one end of the U-shaped scale holder is fixedly connected with the main scale, and a link plate holder is arranged at the other end; the table board of the link plate holder is parallel to the axial direction of the micrometric screw rod; and a positioning column is arranged on the table board of the link plate holder. In the utility model, the process in detecting the eccentricity of the link plate hole is simplified through improvement of a conventional micrometer caliper; meanwhile, as the micrometer caliper per se has higher measuring accuracy, more accurate eccentricity can be obtained during detection, and more accurate trimming parameters of a blanking die can be further acquired to facilitate promptly adjusting the blanking die and improving the product qualification rate.
Description
Technical field
The utility model relates to the technical field of quality detection in the chain and chain-plate manufacture process, particularly a kind of testing tool that is used to detect chain and chain-plate hole off-centre.
Background technology
The off-centre of the chain plate hole of chain is the important technology index in chain production and the use, because the position of the chain plate hole of chain is related to the fitted position of chain, can have influence on chain action effect in use.Existing eccentric detection method is to use three-dimensional to detect or uses vernier caliper to detect.The eccentricity detecting of carrier bar needs repeatedly to carry out at any time in process of production; And when detecting, also want the detected result of correspondence that blanking die is repaired and adjusted; So utilize the three-dimensional detection method not only to require great effort but also time-consuming, also can not accomplish detection at any time; And use vernier caliper to detect detection data out of true, the especially eccentricity detecting of hole flanging inner plate of gained.
Summary of the invention
The purpose of the utility model provides a kind of eccentric testing tool in chain and chain-plate hole that is used to detect, and it can be at any time carries out eccentricity detecting to the carrier bar of finished product, obtain the parameter of blanking die finishing more accurately, and testing process is easy.
For realizing above-mentioned purpose; The technical scheme that the utility model is taked is: a kind of testing tool that is used to detect chain and chain-plate hole off-centre, to form by dip stick and U-shaped chi frame, and dip stick comprises main scale, spiral chi, micrometric screw and vernier adjustment knob; One end of U frame chi frame is fixedly connected main scale; The other end is provided with the carrier bar mounting table, and the table top of carrier bar mounting table is parallel to the axial of micrometric screw, and table top is provided with reference column.
The utility model improves on the basis of existing micrometer caliper; Annexation between main scale in the said dip stick, spiral chi, micrometric screw and the vernier adjustment knob; And the annexation of main scale in U-shaped chi frame and the dip stick, all can be with reference to existing micrometer caliper structure.
Further, for the result who make to measure is more accurate, reference column is perpendicular to the table top of carrier bar mounting table in the utility model, and the reference column diameter is identical with the diameter of chain plate hole to be measured.In the school zero the time, the state that can micrometric screw be propped up reference column is as zero-bit.
When using, at first testing tool is carried out school zero, then carrier bar is placed on the table top of carrier bar mounting table; Make reference column pass one of them chain plate hole; Regulate main scale and the spiral chi of dip stick, make the top of micrometric screw prop up the outward flange of carrier bar, read the scale of dip stick at this moment; Adjustment chain Board position makes reference column pass another chain plate hole, the scale of dip stick when reading micrometric screw equally and propping up the carrier bar outward flange; The absolute value that the scale value that records for twice is subtracted each other is the chain plate hole eccentricity value of required measurement.
The beneficial effect of the utility model is: through existing micrometer caliper is improved, simplified the testing process of chain plate hole eccentricity value; Because the measuring accuracy of micrometer caliper itself is higher, when detecting, can access more accurate eccentricity value simultaneously, and then can access the parameter of blanking die finishing more accurately, be convenient in time blanking die adjusted, improve product percent of pass.
Description of drawings
Shown in Figure 1 is the structural representation of the utility model.
Embodiment
For the content that makes the utility model is more obviously understandable, further describe below in conjunction with accompanying drawing and specific embodiment.
In conjunction with Fig. 1; The utility model is made up of dip stick and U-shaped chi frame 8; Dip stick comprises main scale 5, spiral chi 6, micrometric screw 3 and vernier adjustment knob 7, and an end of U frame chi frame 8 is fixedly connected main scale 5, and the other end is provided with carrier bar mounting table 1; The table top of carrier bar mounting table 1 is parallel to the axial of micrometric screw 3, and table top is provided with reference column 2.Reference column 2 is perpendicular to the table top of carrier bar mounting table 1, and the diameter of reference column 2 is identical with the diameter of chain plate hole to be measured.
The utility model improves on the basis of existing micrometer caliper, also comprises the clamping screw 4 that is used for fixing measuring position and scale; Annexation between main scale in the dip stick, spiral chi, micrometric screw and the vernier adjustment knob, and the annexation of main scale in U-shaped chi frame and the dip stick all can be with reference to existing micrometer caliper structures.
When using, at first testing tool is carried out school zero, in the school zero the time, the state that can micrometric screw be propped up reference column is as zero-bit.Then carrier bar is placed on the table top of carrier bar mounting table, make reference column pass one of them chain plate hole, regulate main scale and the spiral chi of dip stick, make the top of micrometric screw prop up the outward flange of carrier bar, read the scale Y1 of dip stick at this moment; Adjustment chain Board position makes reference column pass another chain plate hole, the scale Y2 of dip stick when reading micrometric screw equally and propping up the carrier bar outward flange; The absolute value that the scale value that records for twice is subtracted each other is the chain plate hole eccentricity value of required measurement, i.e. D1=| Y1-Y2|.
The case of practical implementation described in the utility model is merely the preferable case study on implementation of the utility model, is not the practical range that is used for limiting the utility model.Be that all contents according to the utility model claim are done ground equivalence variation and modified, all should be as the technological category of the utility model.
