Description
Technical field
The utility model relates to miniature parts checkout equipment technical field, is specifically related to a kind of screw mandrel steel ball height and length overall pick-up unit.
Background technology
Screw mandrel steel ball height and length overall pick-up unit are generally used for detecting accurate parameters such as the steel ball height, length overall of screw mandrel part, operating personnel judge according to testing result whether center pit and the length overall of being examined screw mandrel part product meet the requirements, and it is defective not meeting after testing and setting the screw mandrel part product that requires.At present general screw mandrel steel ball height and length overall pick-up unit assist to measure at the steel ball height that detects screw mandrel part product and steel ball of length overall Shi Xuyong, invar pearl volume is less, comparatively inconvenience when pick-up unit picks and places steel ball, this makes screw mandrel manufacturer need more time of cost and manpower in the testing of screw mandrel part product, and whether the center pit and the length overall that can't fast detecting go out screw mandrel part product be qualified, thereby cause the production efficiency of screw mandrel low, manufacturing cost is high.In addition each detect all will do later to steel ball make zero again and registration process, the error that can produce in the process that makes zero again so both reduced the efficient of testing, and error also may influence the accuracy of detection.
The utility model content
Technical problem to be solved in the utility model provides a kind of detection efficiency height, can effectively reduce and detect error and easy-operating screw mandrel steel ball height and length overall pick-up unit.
For effectively solving the problem of above-mentioned technology, the technical scheme that the utility model is realized is: a kind of screw mandrel steel ball height and length overall pick-up unit, comprise base station, base station one end is fixed with gauge stand, clock gauge is installed on the gauge stand, base station middle part is provided with groove seat and the other end and is provided with the thimble seat that can move forward and backward along track, described groove seat two ends are provided with an identical and corresponding left side, right V-shaped groove, be respectively arranged with a left side on gauge stand and the thimble seat, right sphere thimble, left side sphere thimble is connected with the clock gauge chaining pin, right sphere thimble movably is installed in the thimble seat by tailstock barrel, and screw mandrel to be measured is held on a left side, on the right V-shaped groove and screw mandrel two ends are a left side respectively, the terminal concentric alignment of right sphere thimble.
But described gauge stand front end is provided with catch plug, play the effect of setting measurement benchmark when measuring the steel ball height.
The beneficial effects of the utility model are: 1, the utility model adopts end face to be the auxiliary steel ball of spherical top replacement, eliminates to pick and place the inconvenience that steel ball brings and reduce consequent detection error, significantly improves detection efficiency; 2, on the groove seat, be provided for shelving the left and right V-shaped groove of screw mandrel to be measured, save the adjustment screw mandrel and make its this operation of aliging with the thimble end, effectively save detection time; 3, on gauge stand, be provided with and be used to be provided with the catch that requires the testing product margin tolerance, can compare measurement to screw mandrel to be measured, simplify trace routine under the situation of rezero operation.

Fig. 2 is the utility model side-looking structural representation.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing:
As shown in Figure 1, 2, the utility model relates to a kind of screw mandrel steel ball height and length overall pick-up unit, uses this pick-up unit that screw mandrel steel ball height and length overall are detected, not only the detection efficiency height, can effectively reduce and detect error and easy to operate.This device comprises base station, base station one end is fixed with gauge stand 1, clock gauge 11 is installed on the gauge stand, base station middle part is provided with groove seat 2 and the other end and is provided with the thimble seat 3 that can move forward and backward along track, groove seat 2 two ends are provided with an identical and corresponding left side, right V- shaped groove 21,22, be respectively arranged with a left side on gauge stand 1 and the thimble seat 3, right sphere thimble 12,31, left side sphere thimble 12 is connected with the chaining pin of clock gauge 11, right sphere thimble 31 movably is installed in the thimble seat 3 by tailstock barrel 32, and screw mandrel 4 to be measured is held on a left side, right V-shaped groove 21, between 22 and screw mandrel to be measured two ends respectively with a left side, right sphere thimble 12,31 terminal concentric alignment.Wherein but the gauge stand front end can also be provided with catch 13 plug, play the effect of setting measurement benchmark when measuring the steel ball height.It is the spherical employed auxiliary steel ball of the top replacement traditional detection of sphere device that the utility model adopts end face, eliminates pick and place that steel ball brings inconvenient and reduces consequent detection error, can significantly improve detection efficiency; On the groove seat, be provided for shelving the left and right V-shaped groove of screw mandrel to be measured, save the adjustment screw mandrel and make its this operation of aliging with the thimble end, can effectively save detection time; On gauge stand, also be provided with and be used to be provided with the catch that requires the testing product margin tolerance, can compare measurement to screw mandrel to be measured, simplify trace routine under the situation of rezero operation.
When using this measurement device screw mandrel steel ball height, screw mandrel to be measured is put into left and right V- shaped groove 21,22, operator's right hand is withstood right sphere thimble 31 afterbodys and is made the top right-hand member that withstands screw mandrel 4 to be measured of right sphere, thereby make the left end of screw mandrel to be measured contact with the right side of catch 13, this moment, the sphere of left sphere thimble 12 ends contacted with the center pit of screw mandrel left end to be measured, the chaining pin of clock gauge 11 is pushed up back under the effect of thrust, and clock gauge demonstration simultaneously records supplemental characteristic.During practical operation, earlier with a standard screw mandrel product by above-mentioned steps established standards value, again product to be measured is detected successively, only need with clock gauge each show record supplemental characteristic and standard value contrasts, can judge whether to be non-defective unit.
When using this measurement device screw mandrel steel ball length overall, take off catch 13 and right sphere top 31 is fixing, operating personnel's left hand draws back left sphere thimble 12, again screw mandrel to be measured is put into left and right V- shaped groove 21,22, make left sphere thimble 12 return original position to withstand screw mandrel 4 left ends to be measured then, this moment, the center pit at screw mandrel to be measured two ends contacted with the sphere of left and right sphere thimble 12,31 respectively, showed on the clock gauge 11 to record supplemental characteristic.As a same reason, need in the practical operation earlier with a standard screw mandrel product again product to be measured to be detected successively by above-mentioned steps established standards value, only need with clock gauge each show record supplemental characteristic and standard value contrasts, can judge whether to be non-defective unit.
The foregoing description is a preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement also should fall within the protection domain of the present utility model.
