In order to make the objectives, technical solutions, and advantages of the present invention clearer, right with reference to the accompanying drawings and embodiments
The present invention is described in further detail.It should be appreciated that described herein, specific examples are only used to explain the present invention, and does not have to
It is of the invention in limiting.
A kind of screw hole detection device of the invention, as shown in Figs. 1-2, including bracket 1, the first actuator 2, the second actuator
3, guide part 4, the first sliding block 5, the second sliding block 6, telescopic device 7, detector 8, sensor and objective table 9, guide part 4 can be
Guide rail；Preferably, guide rail is arranged two, and parallel and be vertically arranged on bracket 1.First sliding block 5 and the second sliding block 6 are logical
It crosses guide part 4 to be slidably disposed on the bracket 1, the support of guide part 4 and the first sliding block 5 of guidance and the second sliding block 6 are vertically
Mobile, the second sliding block 6 is mounted on 5 top of the first sliding block, and the first actuator 2 is mounted on bracket 1, can be cylinder, cylinder
Output shaft connect with the first sliding block 5, the first sliding block 5 of driving moves up and down vertically, and drives the second sliding block 6 mobile.It is flexible
Device 7 is spindle rotationally arranged on the second sliding block 6, and one end is connect with detector 8, and the other end is connect with the second actuator 3, the
Two actuators 3 can be servo motor, and telescopic device 7 is driven to rotate, and then detector 8 is driven to rotate.Sensor setting exists
Sensing chip is arranged in the side of bracket 1 on the second sliding block 6, and sensor is used to incude the position of the second sliding block 6, i.e. detector 8 is
It is no to be in sensor present position.Preferably, two, respectively first sensor 101, are respectively set in sensor and sensing chip
Two sensors, 102 first sensing chip 103 and the second sensing chip 104.First sensor 101 and second sensor 102 are respectively set
In the two sides of bracket 1, and height is staggered, and a first induction piece 103 and the second sensing chip 104 are separately positioned on the second sliding block
6 two sides, two panels sensing chip is corresponding with sensor respectively, and first sensor 101 is for detecting 8 initial position of detector, and second
Sensor 102, by detecting two positions of detector 8, can more accurately judge for detecting 8 final position of detector
Whether screw hole meets regulation.The underface of detector 8 is arranged in objective table 9, for preventing object to be detected, makes the spiral shell of object to be detected
Hole is directed at detector 8.By the way that two sensors are arranged, the accuracy of detection can be greatly improved.Because if being only arranged one group
Sensor is only capable of one position signal of detection；If this group of sensor is used to detect the final position of detector 8, when to be detected
The threaded hole of object is greater than the diameter of detector, and after the first sliding block 5 moves down, detector 8 stops without object to be detected, also can directly slide
To bottom, sensor detects sensing chip, then equipment can be mistaken for qualified screw thread.And two sensors are set, it is examined at one
During survey, initial position, second sensor 102 detect a final position to the detection of first sensor 101 twice, wherein
First sensor can have a break at 101 position.By inductive signal three times, the accuracy of detection can be greatly improved.Wherein,
Sensor can be close to switch.
In one embodiment, as shown in figure 3, telescopic device 7 includes first sleeve 71, the second casing 72 and limited screw
73, first sleeve 71 is slidably sleeved on the second casing 72, and guide groove 74 is opened up in first sleeve 71, limited screw 73
It is fixed on the second casing 72 across guide groove 74, limited screw 73 and guide groove 74 cooperate, for guiding and limiting first set
Mutual sliding between pipe 71 and the second casing 72.
In one embodiment, the both ends of telescopic device 7 pass through bearing 75 respectively and are rotatably mounted on bracket 1 and second sliding
On block 6.By the way that fulcrum is arranged in telescopic device 7, rotate telescopic device 7 more stable.Wherein, bearing 75 can be using pressure
Power bearing.
In one embodiment, the first actuator 2 is mounted on bracket 1, and opening 11 is opened up on bracket 1, the first actuator 2
Output shaft passes through opening 11 and connect with the first sliding block 5.And then the first sliding block 5 is driven to move up and down vertically by the first actuator 2.
The structure setting can greatly reduce the volume of equipment.
In the use of the present invention, as shown in figures 1 to 6, object to be detected is placed on objective table 9 by operator, detection device
Original state such as Fig. 4 show, then start detection device, the first actuator 2 drives the first sliding block 5 to move down, the second sliding block 6 by
It follows the first sliding block 5 to move down in own wt, while telescopic device 7 being stretched；Until detector 8 is contacted with object to be detected, the
One sensor 101 senses the first sensing chip 103.At this point, being there are certain gap between the first sliding block 5 and the second sliding block 6
The rotation of detector 8 makes the second sliding block 6 is mobile to provide displacement space, reaches position shown in Fig. 5.Second actuator 3 passes through flexible dress
The rotation of 7 driving detectors 8 is set, if the screw thread in the screw thread and screw hole of detector 8 matches, detector 8 can be moved down gradually,
When second sensor 102 senses the second sensing chip 104, then illustrates that detector 8 reaches final position, reach position shown in Fig. 6.
Second actuator 3 rotates backward, and detector 8 is made to screw out the screw hole of object to be detected, and first sensor 101 detects the first sense again
Answer piece 103.First actuator 2 resets, and drives the first sliding block 5 and the second sliding block 6 is driven to move up.It is returned to position as shown in Figure 4
It sets.Staff is waited to replace object to be detected.When sensor sensing is to signal three times, then illustrate that screw hole matches with detector.
In addition, when the first sliding block 5 moves down, detector 8 can also be followed if the screw hole of object to be detected is greater than detector 8
It moves down, until the maximum extension position of arrival telescopic device 7 or detector 8, which refer to, directly hits objective table.At this point, passing through
First sliding block 5 is set as limited block, and then limits the maximum distance of fall of detector 8, and then protects detector 8 and flexible dress
Setting 7 will not damage because of impact.
It should be noted that sensor is just started to work, and in this way can after the first actuator drives the first sliding block to move down
It effectively prevent the erroneous detection of sensor.
The foregoing is merely a prefered embodiment of the invention, practical range not for the purpose of limiting the invention；If not departing from this
The spirit and scope of invention, modify or equivalently replace the present invention, and should all cover the protection in the claims in the present invention
In range.
