Abstract
The utility model discloses screw hole detection devices, including screw rod, with the driving device for driving the screw rod rotation, the screw rod is divided into two-section, first cut position is provided with the second screw thread on described second section in being provided with the first screw thread on the end of the screw rod, described first section, first major diameter of thread is less than the internal diameter for the screw hole to be detected, and the outer diameter of second screw thread is greater than the internal diameter of the screw hole.When use, the screw hole that we will first detect is placed in the bottom of screw rod, then driving device is opened, screw rod moves down, screw rod rotation simultaneously, screw rod is inserted into the through-hole to be detected, if the first screw thread can smoothly pass through screw hole on screw rod, and second screw thread cannot pass through screw hole, then prove that screw thread is qualified, if the first screw thread cannot pass through screw hole, or second screw thread also can pass through screw hole then prove that screw hole is underproof, this mode, only a piece screw rod of needs can complete the detection of screw hole for we, and the components such as torsion sensor are not used in our equipment, therefore structure also greatly simplifies, advantage of lower cost.
Description
Technical field
The utility model relates to product testing technical fields, more particularly, to screw hole detection device.
Background technique
Product requires to be detected after processing screw hole, and there are two purposes for this detection, and one is to detect whether
There is the part for having leaked processing screw thread, another is whether the screw thread of detection processing meets technical requirements.Previous detection scheme
It is to be carried out by two standard studs, first stud wants energy precession to go, and second stud will be unable to precession and go, and thus can
Judge whether screw hole is qualified, but this scheme, a screw hole is detected with two studs, it is inconvenient.
Also have in society using the stud to match with screw hole and detects whether screw hole is qualified, it includes a driving stud
The testing agency of stress when the driving mechanism of rotation and detection stud rotation, by stress of the detection stud in precession screw hole come
Judge whether screw hole is qualified, but this scheme, the mechanism of equipment are sufficiently complex, therefore also it is necessary to improve.
Summary of the invention
The utility model aiming at the shortcomings in the prior art, provides a kind of screw hole detection device, can easily detect
Whether screw hole is qualified, and structure is simple, and cost is relatively low.
In order to solve the above technical problems, the utility model is addressed by following technical proposals: screw hole detection device, packet
Screw rod is included, and the driving device of the driving screw rod rotation, the screw rod are divided into two-section, first cut position is in the screw rod
End is provided with the first screw thread on described first section, the second screw thread is provided on described second section, first major diameter of thread is small
In the internal diameter for the screw hole to be detected, the outer diameter of second screw thread is greater than the internal diameter of the screw hole.In use, we will first examine
The screw hole of survey is placed in the bottom of screw rod, then opens driving device, and screw rod moves down, while screw rod rotates, and screw rod insertion is wanted
In the through-hole of detection, if the first screw thread can smoothly pass through screw hole on screw rod, and the second screw thread cannot pass through screw hole, then demonstrate,proves
Bright screw thread is qualified, if the first screw thread cannot pass through screw hole, or the second screw thread can also pass through screw hole if proves that screw hole is
Underproof, this mode, we only need a screw rod that can complete the detection of screw hole, and do not use in our equipment
The components such as torsion sensor, therefore structure also greatly simplifies, advantage of lower cost.
In above-mentioned technical proposal, it is preferred that first screw thread is provided with three circles or more, and second screw thread is provided with one
It is more than circle.First thread turns will affect the accuracy of detection very little, as long as but the second screw thread have a circle it may determine that.
In above-mentioned technical proposal, it is preferred that the distance between first screw thread and second screw thread are greater than the spiral shell
The depth in hole.In this way, may insure the independence of the first screw thread and the second thread measurement.
The beneficial effects of the utility model are: in use, the screw hole that we will first detect is placed in the bottom of screw rod, then
Driving device is opened, screw rod moves down, while screw rod rotates, and screw rod is inserted into the through-hole to be detected, if first on screw rod
Screw thread can smoothly pass through screw hole, and the second screw thread cannot pass through screw hole, then prove screw thread be it is qualified, if the first screw thread
Cannot pass through screw hole or the second screw thread also can then prove that screw hole is underproof, this mode across screw hole, we only need
A piece screw rod can complete the detection of screw hole, and the components such as torsion sensor not used in our equipment, therefore structure
It greatly simplifies, advantage of lower cost.
Detailed description of the invention
Fig. 1 is utility model diagram.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
Referring to Fig. 1, screw hole detection device, including screw rod 1, and the stepper motor 2 of the driving screw rod rotation, stepper motor
On guides 3, guide rail 3 is mounted on bracket 4 for 2 installations, and the screw rod 1 divides for two-section, and described first section 11 is located at the screw rod 1
End, be provided with the first screw thread 1a, the first screw thread 1a on described first section 1 and be provided with three circles or more.
It is provided with the second screw thread 1b, the second screw thread 1b on described second section 12 and is provided with a circle or more.Described first
Screw thread 1a outer diameter is less than the internal diameter for the screw hole 3 to be detected, and the outer diameter of the second screw thread 1b is greater than the internal diameter of the screw hole 3.
In use, the screw hole that we will first detect is placed in the bottom of screw rod, driving device is then opened, screw rod is transported down
It is dynamic, while screw rod rotates, screw rod is inserted into the through-hole to be detected, if the first screw thread can smoothly pass through screw hole on screw rod,
And second screw thread cannot pass through screw hole, then prove that screw thread is qualified, if the first screw thread cannot pass through screw hole or the second spiral shell
Line, which can also pass through screw hole, then proves that screw hole is underproof, this mode, we only need a screw rod that can complete screw hole
Detection, and the components such as torsion sensor are not used in our equipment, therefore structure also greatly simplifies, advantage of lower cost.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality
Example is applied the utility model is described in detail, those skilled in the art should understand that: it still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features；And these
It modifies or replaces, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
