Abstract
The utility model discloses a piston rod double-flat symmetry simple detection tool. The piston rod double-flat symmetry simple detection tool can perform gross detection on the double-flat symmetry of a piston rod after double-flat processing so as to prevent unqualified products from entering a next process and save processing cost. The piston rod double-flat symmetry simple detection tool includes a tool body. The tool body is provided with a detection basic flat hole and a detection basic round hole along the length direction, wherein the detection basic flat hole is communicated with the detection basic round hole; the detection basic flat hole is matched with a tail end of the piston rod; the detection basic flat hole is provided with two detection basic surfaces which are in up-down symmetry; and the diameter of the detection basic round hole is corresponding to a middle portion cylinder of the piston rod. Knurled patterns are pressed on the outer surface of the tool body. The piston rod double-flat symmetry simple detection tool can perform gross detection on the double-flat symmetry of the piston rod after the double-flat processing so as to prevent the unqualified products from entering a next process and save processing cost. The piston rod double-flat symmetry simple detection tool is advantageous in structural simplicity, convenient operation and low usage cost; and at the same time, the piston rod double-flat symmetry simple detection tool can also detect the diameter of the middle portion of the piston rod.
Description
Technical field
The utility model relates to the two flat symmetry simple detection instruments of a kind of piston rod.
Background technology
The two flat symmetry of piston lever of reducer for automobile is the important detected parameters of product quality.At present, in the production run of piston lever of reducer for automobile, because two flat symmetry adopts task equipment accurately to detect, testing process is loaded down with trivial details, generally all is the detection of just carrying out two flat symmetries in to the finished product detection process.If directly do not detect after two flat processing so that the underproof product introduction of two flat symmetries the processing of subsequent processing, increased production cost.
The utility model content
The purpose of this utility model is for the technological deficiency that exists in the prior art, and provide a kind of piston rod two flat symmetry simple detection instruments, can after two flat processing, carry out Rough Inspection by the two flat symmetry to piston rod, prevent underproof product introduction subsequent processing, save processing cost.
For realizing that the technical scheme that the purpose of this utility model adopts is:
The two flat symmetry simple detection instruments of a kind of piston rod, it is characterized in that, comprise the frock body, be provided with along its length the flat hole of detection reference and the detection reference circular hole of connection on the described frock body, match with the piston rod afterbody in the flat hole of described detection reference, the flat hole of described detection reference has the up and down detection reference face of two symmetries, and the diameter of described detection reference circular hole is corresponding with the middle part right cylinder of piston rod.
The outside surface of described frock body is pressed with the annular knurl line.
Compared with prior art, the beneficial effects of the utility model are:
1, the two flat symmetry simple detection instruments of piston rod of the present utility model can carry out Rough Inspection by the two flat symmetry to piston rod after two flat processing, prevent underproof product introduction subsequent processing, save processing cost.And simple in structure, easy and simple to handle, use cost is low.
2, the two flat symmetry simple detection instruments of piston rod of the present utility model can also detect the diameter at piston rod middle part.
Description of drawings
Figure 1 shows that the synoptic diagram of the two flat symmetry simple detection instruments of piston rod of the present utility model;
Figure 2 shows that the right view of Fig. 1;
Figure 3 shows that the synoptic diagram that uses testing tool of the present utility model to detect.
Among the figure: 1. the flat hole of detection reference, 2. annular knurl line, 3. frock body, 4. detection reference circular hole, 5. piston rod.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The synoptic diagram of the two flat symmetry simple detection instruments of the utility model piston rod as shown in Figure 1 and Figure 2, comprise frock body 3, be provided with along its length the flat hole 1 of detection reference and the detection reference circular hole 4 of connection on the described frock body 3, match with the afterbody of piston rod in the flat hole 1 of described detection reference, the flat hole of described detection reference has the up and down detection reference face of two symmetries, be the detection reference face of A, two symmetries of B, the diameter of described detection reference circular hole 4 is corresponding with the middle part right cylinder of piston rod.
Manually hand-held convenient during for the ease of detection, the outside surface of described frock body 3 is pressed with annular knurl line 2.
Use synoptic diagram that testing tool of the present utility model detects as shown in Figure 3, piston rod 5 afterbodys are inserted in the flat hole 1 of detection reference, insert in the detection reference circular hole 4 at the middle part of piston rod, if two flat up and down two planes of symmetry of piston rod are identical with two detection reference faces of A, B in the flat hole of detection reference, the two flat plane of symmetry that then represents product is qualified, if between two detection reference faces of A, B in two flat up and down two planes of symmetry of piston rod and the flat hole of detection reference error is arranged, represent that then product is defective, underproof product can not enter subsequent processing.Instrument of the present utility model can also detect the diameter at piston rod middle part, if the middle part of piston rod and detection reference circular hole match, is specification product, if between piston rod middle part and the detection reference circular hole error is arranged, then is substandard product.
The above only is preferred implementation of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. two flat symmetry simple detection instruments of a piston rod, it is characterized in that, comprise the frock body, be provided with along its length the flat hole of detection reference and the detection reference circular hole of connection on the described frock body, match with the piston rod afterbody in the flat hole of described detection reference, the flat hole of described detection reference has the up and down detection reference face of two symmetries, and the diameter of described detection reference circular hole is corresponding with the middle part right cylinder of piston rod.
2. the two flat symmetry simple detection instruments of piston rod according to claim 1 is characterized in that the outside surface of described frock body is pressed with the annular knurl line.
