The rotating block is a cylinder, and the axial line of the through hole A is coincided with the axial line of the cylinder. A through hole is formed in the radial direction of the through hole B of the rotating block and is connected with a fastening bolt through a thread, and the measuring rod is matched with the through hole B through the fastening bolt. The rotating block is the cylinder with a notch, and the through hole connected with the fastening bolt through the thread is arranged on the notch. The provided screw thread hole verticality inspection tool has the advantages of simple structure, low cost, convenient use, high precision and high validity of inspection of the verticality of the hole and the surface of the workpiece; and the screw thread hole verticality inspection tool meets various requirements for measuring the verticality of the workpiece.
Description
Technical field
The utility model relates to a kind of verticality cubing, more specifically says, it relates to a kind of threaded hole verticality cubing.
Background technology
A lot of equipment have requirement to the verticality of used threaded hole.As detent caliper support is the strength member that connects caliper and steering knuckle, normally being connected with the realization of two bolts and steering knuckle.Therefore, support two connection screws and screw installed surface verticality quite show important.Generally require hole, face verticality to be controlled in the 0.10mm, under the product lot quantity condition of production, must have reasonable, effective appliance special for detecting to detect this and require size, to guarantee product quality.In the present prior art high precision cubing that detects at the threaded hole verticality is not specially arranged also, and general verticality cubing complex structure uses inconvenience, precision is not high, is used for the detection of threaded hole verticality and causes the measurement mistake easily.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of simple in structure, easy to use, threaded hole verticality cubing that precision is high is provided.
Threaded hole verticality cubing of the present utility model, comprise spill spin block, positioning screw, dial bore gage, described spill spin block is provided with two axial parallel through hole A and through hole B, match with through hole A in the positioning screw upper end, the positioning screw lower end is provided with the screw thread of band tapering, and the gauge rod of dial bore gage matches with through hole B.
Spill spin block is a right cylinder, and the axis of through hole A overlaps in cylinder axis.
Spill spin block directly upwards is provided with through hole at through hole B and is threaded with fastening bolt, and gauge rod matches with through hole B by fastening bolt.Spill spin block is the right cylinder that a breach is arranged, and the described through hole that is threaded with fastening bolt is located on the breach.
Owing to adopt technique scheme, reasonable combination by positioning screw, spill spin block, dial bore gage etc., the threaded hole verticality cubing that the utility model provides is simple in structure, with low cost, easy to use, precision is high, it is strong that workpiece hole, face verticality are detected validity, reaches every requirement of measuring workpieces verticality.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further.Though the utility model will be described in conjunction with preferred embodiment, should know, do not represent that the utility model is limited among the described embodiment.On the contrary, the utility model will be contained alternative, modified and the equivalent in the scope of the present utility model that can be included in attached claims qualification.
Referring to Fig. 1-4, the threaded hole verticality cubing of Jie Shaoing generally is used for the verticality detection of threaded hole here, yet should know, the verticality that the utility model also can be used for other structures detects.Threaded hole verticality cubing, comprise spill spin block 2, positioning screw 4, dial bore gage 1, described spill spin block 2 is provided with two axial parallel through hole A5 and through hole B6, match with through hole A5 in positioning screw 4 upper ends, positioning screw 4 lower ends are provided with the screw thread of band tapering, and the gauge rod 7 of dial bore gage 1 matches with through hole B6.Spill spin block 2 is a right cylinder, and the axis of through hole A5 overlaps in cylinder axis.Spill spin block 2 directly upwards is provided with through hole at through hole B6 and is threaded with fastening bolt 3, and gauge rod 7 matches with through hole B6 by fastening bolt 3.Spill spin block 2 has a breach on right cylinder, the described through hole that is threaded with fastening bolt 3 is located on the breach.
When the threaded hole verticality cubing of present embodiment was made, positioning screw 4 threaded portions should be the taper thread with measured workpiece screw thread same specification, and it is actual definite that reach is pressed workpiece, to guarantee good location.Spill spin block 2 both ends of the surface and through hole A5 and through hole B6 verticality must be less than 0.005mm, and the end face roughness will meet the drawing requirement.Positioning screw 4 all needs Quenching Treatment with spill spin block 2 and meets the requirements, and both holes, axle require clearance fit, and tolerance clearance is not more than 0.005mm, and cooperating the back to rotate must be flexibly.
Before the measurement, positioning screw 4 is screwed in the measured workpiece screw, then spill spin block 2 is installed on the positioning screw 4, unscrew fastening bolt 3, (the good indicator of pre-adjustment points to dial bore gage 1, make it to zero-bit) be inserted on the spill spin block 2, note adjusting the height of gauge head 8, (make indicator turn clockwise 0.30mm) gauge head 8 contacts with measured.
During measurement, note manual uniform rotation spill spin block 2, rotate a few, observe the maximum variation of dial bore gage 1 pointer, do not allow to surpass 90% of workpiece requirement.
Present embodiment is suitable for and detects workpiece screw and screw end face squareness.Detected face directly is Φ 25 or more (is the center with the positioning screw hole), and the requirement of detected hole perpendicularity is not less than the workpiece of 0.03mm.
