Abstract
The utility model provides a kind of roughness instrument protective device.Described roughness instrument protective device comprises support portion, driving section, protection portion and syndeton; described support portion one side surface connects described driving section; its opposite flank connects described protection portion; described syndeton is located at surface, described driving section; described support portion comprises perforation; described perforation runs through described support portion, and described protection portion correspondence is located at described perforation.The roughness instrument protective device that the utility model provides is reasonable in design, can improve the operating efficiency that roughness instrument detects, can better protect again roughness instrument itself and chaining pin thereof, simple to operate, easy to use.
Description
Technical field
The utility model relates to protective device, especially, relates to a kind of roughness instrument protective device.
Background technology
In prior art; company is for adapting to Production requirement; roughness parameter after using roughness instrument to detect small-bore cylinder body cylinder-bore hone; in the actual use of production; because of the design feature of equipment self; cause detecting hone rear cylinder bore parameter efficiency on the low side, in order to increase work efficiency and better protect roughness instrument itself and chaining pin, devise a protective device used for roughness instrument.
Utility model content
Detect hone rear cylinder bore parameter efficiency technical problem on the low side for solving above-mentioned roughness instrument, the utility model provides a kind of roughness instrument protective device, and this device can be increased work efficiency, and better protects roughness instrument itself and chaining pin thereof.
The roughness instrument protective device that the utility model provides; comprise support portion, driving section, protection portion and syndeton; described support portion one side surface connects described driving section; its opposite flank connects described protection portion; described syndeton is located at surface, described driving section; described support portion comprises perforation, and described perforation runs through described support portion, and described protection portion correspondence is located at described perforation.
In a kind of preferred embodiment of the roughness instrument protective device provided at the utility model, described driving section comprises leading screw.
In a kind of preferred embodiment of the roughness instrument protective device provided at the utility model, described protection portion is cylinder jacket.
In a kind of preferred embodiment of the roughness instrument protective device provided at the utility model, described syndeton is nipple.
Compared to prior art, the advantage of roughness instrument protective device of the present utility model is:
One, support portion adopts acrylic board to make, and this material is light, can not scratch surface of the work in carrying.
Two, driving section adopts leading screw principle, and make the roughmeter after assembling, can measure the roughness parameter of optional position in chaining pin range and minimum stroke, simple to operate, stability is fine.
Three, because roughness instrument chaining pin is made up of pottery; the thermal deformation coefficient of pottery chaining pin self; permeability is all very little; can not because of the change of environment temperature; the magnetic influence measurement data authenticity of surrounding environment, just ceramic material pliability is poor, adopts protection portion protection chaining pin; the service life of chaining pin can be extended, and keep the precision of roughness instrument.
Four, syndeton by roughness instrument and roughness instrument protective device with being threaded, for convenience detach, good stability.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the roughness instrument protective device that the utility model provides;
Fig. 2 is the structural representation of the support portion of the roughness instrument protective device that the utility model provides.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1 and Fig. 2, wherein Fig. 1 is the structural representation of the roughness instrument protective device that the utility model provides, and Fig. 2 is the structural representation of the support portion of the roughness instrument protective device that the utility model provides.
Described roughness instrument protective device 100 comprises support portion 1, driving section 2, protection portion 3 and syndeton 4; described support portion 1 one side surface connects described driving section 2; its opposite flank connects described protection portion 3, and described syndeton 4 is located at surface, described driving section 2.
Described support portion 1 comprises perforation 11, and described perforation 11 runs through described support portion 1, and described protection portion 3 correspondence runs through described perforation 11.
In specific embodiment, described support portion 1 adopts acrylic board to make, and this material is light, can not scratch surface of the work in carrying.Driving section, described driving section 2 adopts leading screw principle, and make the roughness instrument after assembling, can measure the roughness parameter of optional position in chaining pin range and minimum stroke, simple to operate, stability is fine.
Because roughness instrument chaining pin is made up of pottery; the thermal deformation coefficient of pottery chaining pin self; permeability is all very little; can not because of the change of environment temperature; the magnetic influence measurement data authenticity of surrounding environment, just ceramic material pliability is poor, and described protection portion 3 protects the chaining pin of roughmeter; the service life of chaining pin can be extended, and keep the precision of roughness instrument.Described syndeton 4 by roughness instrument and described roughness instrument protective device 100 with being threaded, for convenience detach, good stability.
Compared with prior art, the roughness instrument protective device that the utility model provides is reasonable in design, and the operating efficiency that can improve the detection of roughness instrument can better protect again roughness instrument itself and chaining pin thereof, simple to operate, easy to use.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
