Abstract
The utility model relates to a detection tool of a keyway, and in particular to a keyway width detection tool. The keyway width detection tool comprises a dial indicator, a detection body and a standard check block. The dial indicator is fixed on the detection body through bolts. The front end of the detection body is provided with a keyway gauge; the middle part of the detection body is provided with an elastic groove; and the part of the elastic groove facing the extension part of the keyway gauge is provided with an elastic groove opening. The measuring head of the dial indicator is pressed in the elastic groove opening. The standard check block is provided with a groove which is matched with the keyway gauge, and the standard check block is used for checking the standard size of the detection tool. The keyway width detection tool has a simple and reasonable structure and can be conveniently operated and accurately detect the actual width of the keyway.
Description
Technical field
The utility model relates to the testing tool of keyway, specifically a kind of width of keyway cubing.
Background technology
In the prior art, width of keyway normally adopts the keyway feeler gauge to detect, and can only judge that whether qualified width of keyway is, and the feeler gauge size immobilizes, and adopts feeler gauge can't accurately detect the developed width value of keyway.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, makes simply, and is easy to operate, the width of keyway cubing that detection efficiency is high.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of width of keyway cubing comprises clock gauge, cubing body, standard proof-reading block; Clock gauge is screwed on the cubing body; Cubing body front end is provided with keyseat gauge; Have elastic groove in the middle of the cubing body, elastic groove forms the elasticity notch to the extension of keyseat gauge; The clock gauge gauge head is pressed in the elasticity notch; Be provided with the groove that cooperates with keyseat gauge on the described standard proof-reading block, be used for the check and correction of cubing standard size.
The keyseat gauge two sides stud with wimet, can fit tightly keyway to be detected both sides and detect the developed width of keyway.
Width of keyway cubing of the present utility model is simple and reasonable, easy to operate, can accurately detect the developed width of keyway.
Description of drawings
Fig. 1 is the structural representation of the utility model width of keyway cubing;
Fig. 2 is the use constitutional diagram of the utility model width of keyway cubing;
Among the figure: 1. clock gauge; 2. cubing body; 3. keyseat gauge; 4. elastic groove; 5. standard proof-reading block; 6. groove; 7. workpiece to be detected.
Embodiment
As shown in Figure 1, a kind of width of keyway cubing, it comprises clock gauge 1, cubing body 2, standard proof-reading block 5, clock gauge 1 is screwed on cubing body 2; Cubing body 2 front ends are provided with keyseat gauge 3; Have elastic groove 4 in the middle of the cubing body 2, elastic groove 4 forms the elasticity notch to the extension of keyseat gauge 3; The clock gauge gauge head is pressed in the elasticity notch; Be provided with the groove 6 that cooperates with keyseat gauge on the standard proof-reading block 5, be used for the check and correction of cubing standard size.
Keyseat gauge 3 two sides stud with wimet, can fit tightly keyway to be detected both sides and detect the developed width of keyway, make that to detect data more accurate.
As shown in Figure 2, when width of keyway cubing of the present utility model is used, when the keyseat gauge 3 of cubing body 2 inserts the keyway of workpiece 7 to be detected, the keyseat gauge elastic deformation of cubing body front end, fit tightly with tested keyway, just can accurately detect the developed width of keyway, and read concrete width value by clock gauge 1.
Claims (2)
1. width of keyway cubing, it is characterized in that: comprise clock gauge, cubing body, standard proof-reading block, clock gauge is screwed on the cubing body; Cubing body front end is provided with keyseat gauge; Have elastic groove in the middle of the cubing body, elastic groove forms the elasticity notch to the extension of keyseat gauge; The clock gauge gauge head is pressed in the elasticity notch; Be provided with the groove that cooperates with keyseat gauge on the described standard proof-reading block.
