Description
Technical field
The utility model relates to a kind of Rockwell Hardness meter, and more particularly, it relates to a kind of Rockwell Hardness meter for detecting bolt.
Background technology
Rockwell's hardness detection method is proposed in 1914 by American Rockwell (S.P.RocKwell and H.M.RocKwell) at first.They improve scleroscopic design for twice 1919 and nineteen twenty-one later, establish the blank of modern Rockwell hardometer, Renewal Design has been carried out to nineteen thirty Wilson's (C.H Wilson), make Rockwell's hardness detection method and equipment more perfect, use till today always, present China production numeral method the Rockwell's hardness master of automatic printing is straight, the feature of Rockwell's hardness detection method is simple to operate, measure rapidly, and can from dial gauge or optical projection screen or display screen direct reading, the same with Vickers hardness detection method with Bu Shi, become one of three kinds of the most frequently used hardness determination methods.
In testing process, usually direct product is placed on worktable on the surface, Rockwell Hardness detection can be carried out to this product after setting level, but because bolt head is circular arc a bit, make easily to measure time bolt is placed, measuring process is inconvenient, used has certain room for improvement for the Rockwell Hardness meter detecting bolt so current.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of Rockwell Hardness meter bolt can fixed when detecting bolt.
For achieving the above object, the utility model provides following technical scheme: a kind of Rockwell Hardness meter for detecting bolt, comprise worktable, described worktable is provided with the standing groove placed for bolt head, described worktable is provided with at least two pieces of fixture blocks for standing screw, described fixture block is with the center of standing groove for rotational symmetry is arranged at the both sides of standing groove, and described worktable is provided with the chute for fixture block slippage, is fixedly connected with elastic component between described two fixture blocks.
Preferably, described fixture block is provided with limited block, is provided with the stopper slot for limited block slippage in described chute.
Preferably, described limited block is provided with elastic bumps, is provided with the groove worn for elastic bumps in described stopper slot.
Preferably, described fixture block is provided with grip part.
The utility model hinge structure is compared to be had: promote fixture block by grip part and standing groove is opened, simultaneously elastic component is stretched generation elastic deformation, the head of bolt is placed in standing groove, after removing external force, screw rod blocks by fixture block under the effect of elastic component, thus bolt is fixed, carry out carrying out Rockwell Hardness measurement to bolt to facilitate, avoid bolt swaying style and cause the troublesome situation of detection to occur.

Embodiment
Shown in Fig. 6, embodiment is described further.
A kind of Rockwell Hardness meter for detecting bolt disclosed in the utility model, comprise worktable 1, being placed on stably by product can to Product checking Rockwell Hardness on worktable 1, worktable 1 is provided with the standing groove 3 placed for bolt head 2, the diameter of standing groove 3 is slightly larger than the diameter of bolt head 2, put into facilitate bolt head 2, and a preliminary location is carried out to bolt, because bolt head 2 is placed in standing groove 3, if bolt is toppled over, then the screw rod 4 of bolt can be conflicted mutually with the edge of standing groove 3, bolt can not be toppled over completely, to facilitate, bolt is fixed, worktable 1 is provided with at least two pieces of fixture blocks 5 for standing screw 4, fixture block 5 with the center of standing groove for rotational symmetry is arranged at the both sides of standing groove 3, worktable 1 is provided with the chute 6 for fixture block 5 slippage, fixture block 5 is made to be free to slippage in chute 6, there will not be the phenomenon of clamping stagnation, elastic component 7 is fixedly connected with between two fixture blocks, elastic component 7 is preferably spring, it should be noted that herein, together with elastic component 7 can be relatively fixed by welding with fixture block, or can by bonding, the ways customary such as clamping reach the object be fixedly connected with, above-mentioned connected mode, it is all technological means well-known to those skilled in the art, be not described further herein, when spring in the raw time, spacing between the fixture block 5 of standing groove 3 both sides is less than the diameter of screw rod 4, screw rod 4 on bolt can be blocked by fixture block 5, to realize the fixing function of bolt, conveniently Rockwell's hardness detection is carried out to bolt.
Fixture block 5 is provided with limited block 8, the stopper slot 9 for limited block 8 slippage is provided with in chute 6, skid off in stopper slot 9 to prevent limited block 8, cause fixture block 5 from chute 6 landing and cause elastic component 7 stretch exceed elastic limit and cause damage, and then cause the fixed function of fixture block 5 to lose efficacy, limited block 8 is provided with elastic bumps 10, elastic bumps 10 can be rubber bumps and jumping bean spring, but elastic bumps 10 of the present utility model is preferably jumping bean spring, because the fixing better effects if of jumping bean spring, the groove 11 worn for elastic bumps 10 is provided with in stopper slot 9, being worn by elastic bumps 10 enters in groove 11, standing groove 3 can be fixed on after opening in chute 6 by fixture block 5 slippage, put in standing groove 3 to facilitate bolt, and only have and just can be skidded off in groove 11 by External Force Acting elastic bumps 10, the elastic force effect of elastic component 7 again by being stretched, bolt is blocked, be fixed in standing groove 3, fixture block 5 is provided with grip part 12, grip part 12 is fixedly connected with fixture block 5, it should be noted that herein, together with grip part 12 can be relatively fixed by screw thread with fixture block 5, or can by bonding, the ways customary such as clamping reach the object be fixedly connected with, above-mentioned connected mode, it is all technological means well-known to those skilled in the art, be not described further herein, make can make fixture block slippage in chute 6 by the grip part 12 that mops floor, to facilitate, bolt is placed in standing groove 3.
When needs detect bolt time, first to be slided fixture block 5 by grip part 12, the fixture block 5 of both sides is opened, simultaneously elastic component 7 is stretched generation elastic deformation, and standing groove 3 is opened, in groove 11, fixture block 5 is fixed in chute 6 until elastic bumps 10 is located in, the head of bolt is placed in standing groove 3, stir grip part 12, elastic bumps 10 is made to skid off groove 11, the screw rod 4 of bolt is fixed by fixture block 5 under the elastic force effect of elastic component 7, thus will be bolted in standing groove 3, is carrying out Rockwell Hardness detection to bolt.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
