Description
Technical Field
The invention relates to the field of detection, in particular to a multifunctional detection method for a pivot mechanism.
Background
Referring to fig. 1, fig. 1 shows a pivot mechanism (hinge) on a notebook computer, the pivot mechanism includes a large fixing frame 1 and a small fixing frame 2, the large fixing frame 1 and the small fixing frame 2 are both in a sheet shape, the large fixing frame 1 and the small fixing frame 2 are rotatably connected together through a rotating shaft 3, and the large fixing frame 1 and the small fixing frame 2 are respectively fixed on a screen cover and a keyboard base of the notebook computer, so that the relative overturning between the screen cover and the keyboard base of the notebook computer is realized.
After the pivot mechanism is produced and processed, the detection tool is required to be used for detecting abnormal sound, angles and the like of the pivot mechanism so as to detect whether the pivot mechanism is qualified in production. At present, when different items are detected by the pivot mechanism, different detection tools need to be used for independent detection, and the pivot mechanism to be detected needs to be continuously taken and placed, so that the detection speed is low and the detection efficiency is low during detection.
Disclosure of Invention
The invention aims to provide a multifunctional detection method for a pivot mechanism, so as to improve the detection efficiency of the pivot mechanism.
In order to achieve the purpose, the technical scheme of the invention is as follows: the pivot mechanism is detected on detection equipment in a one-way fixed type or two-way fixed type, a clamping groove and a rotating shaft groove are arranged on the detection equipment, and the pivot mechanism is detected by the following steps:
A. abnormal sound detection is carried out on the small fixing frame: inserting the large fixing frame into a clamping groove on the detection equipment, and fixing the large fixing frame by using the clamping groove; then the rotating shaft is inserted into a rotating shaft groove on the detection equipment, so that the small fixing frame continuously rotates twice, and whether abnormal sound exists or not is judged;
B. abnormal sound and rotation angle detection are carried out on the large fixing frame: inserting the small fixing frame into the clamping groove, fixing the small fixing frame by using the clamping groove, and inserting the rotating shaft into the rotating shaft groove to enable the large fixing frame to continuously rotate twice, so that whether abnormal sound exists or not is judged; and meanwhile, the position of the large fixing frame relative to the arc mark on the detection equipment is observed, so that the rotation angle of the large fixing frame is detected.
The working principle and the effect of the scheme are as follows: the unidirectional fixed type is that when the pivot mechanism is detected, a large fixed frame or a small fixed frame of the pivot mechanism is clamped and fixed by the detection mechanism, and the large fixed frame and the small fixed frame cannot be fixed at the same time. The bidirectional fixed type is that when the pivot mechanism is detected, the large fixing frame and the small fixing frame of the pivot mechanism are clamped and fixed by the detection mechanism at the same time. No matter what kind of mode's check out test set is taken, all can be equipped with centre gripping groove and pivot groove on the check out test set, and the centre gripping groove is used for holding pivot mechanism's big mount or little mount. The rotating shaft groove is used for accommodating a rotating shaft of the pivot mechanism. In the step A, the large fixing frame is inserted into the clamping groove, the large fixing frame is fixed by using the clamping groove, the rotating shaft is inserted into the rotating shaft groove, a certain gap is formed between the rotating shaft and the inner wall of the rotating shaft groove, the rotating shaft can rotate in the rotating shaft groove, and at the moment, the small fixing frame is continuously rotated twice, so that the existence of abnormal sound of the small fixing frame is judged, and the abnormal sound detection of the small fixing frame is completed. Step B, inserting the small fixing frame into the clamping groove, fixing the small fixing frame by using the clamping groove, inserting the rotating shaft into the rotating shaft groove, and continuously rotating the large fixing frame twice at the moment to judge whether the large fixing frame has abnormal sound, so that abnormal sound detection of the large fixing frame is completed; and the big mount is longer, and big mount can instruct the arc mark on, and big mount rotation in-process detects the turned angle of big mount through the arc mark to detect whether qualified pivot mechanism's turned angle. Through this scheme, need not to detect when can realizing different sound of pivot mechanism and turned angle on the utensil is examined to the difference, do benefit to the efficiency that improves the detection.
Further, when the detection equipment is in a one-way fixed type, in the step B, before the large fixing frame rotates, a protection tube is sleeved on the large fixing frame, and after the large fixing frame finishes detection, the protection tube is taken down. When the detection equipment is in a one-way fixed type, the rotation of the large fixing frame or the rotation of the small fixing frame is directly pushed by hands, but in the process of pushing the large fixing frame to rotate, the large fixing frame is easy to bend due to the fact that the large fixing frame is long and is pushed by hands, and in order to avoid bending due to the fact that the large fixing frame is pushed by hands, before the large fixing frame is pushed, a protective tube can be sleeved on the large fixing frame, and the large fixing frame can rotate relative to the rotating shaft by pushing the protective tube. The protection tube plays a role in protecting the large fixing frame and cannot push and bend the large fixing frame.
Further, in the step A, after the large fixing frame is inserted into the clamping groove, the large fixing frame is fixed by using a clamping mechanism; and step B, after the small fixing frame is inserted into the clamping groove, fixing the large fixing frame by using a clamping mechanism. Therefore, when the large fixing frame or the small fixing frame is inserted into the clamping groove, the large fixing frame or the small fixing frame can be fixed through the clamping mechanism, and the clamping groove can clamp the large fixing frame or the small fixing frame more stably.
Further, the order of step a and step B may be changed. Therefore, the detection sequence can also be that the large fixing frame is detected first, and then the small fixing frame is detected. The detection sequence is not limited to detecting the small fixing frame first and then detecting the large fixing frame. The detection sequence is more flexible.
Further, when the detection equipment is of a bidirectional fixed type, the detection equipment comprises a first clamping block for clamping the large fixing frame and a second clamping block for clamping the small fixing frame, and the first clamping block and the second clamping block are arranged in a relative rotating mode; step A, when the small fixing frame is detected, the first clamping block is fixed, and a second push rod on the second clamping block is pushed to enable the second clamping block to rotate; and B, when the large fixing frame is detected in the step B, fixing the second clamping block, and pushing a first push rod on the first clamping block to enable the first clamping block to rotate. Therefore, the large fixing frame is placed in the clamping groove of the first clamping block, the small fixing frame is placed in the clamping groove of the second clamping block, and the large fixing frame and the small fixing frame are fixed by the first clamping block and the second clamping block respectively. Then, in the step A, the second clamping block is fixed, the first clamping block can be rotated by pushing the first push rod, and the first clamping block drives the large fixing frame to rotate relative to the rotating shaft, so that abnormal sound and angle detection of the large fixing frame are realized, and hands do not need to directly act on the large fixing frame. In the step B, after the first clamping block is fixed and cannot rotate, the second push rod is pushed to enable the second clamping block to rotate, and the second clamping block drives the small fixing frame to rotate relative to the rotating shaft, so that abnormal sound detection of the small fixing frame is achieved. Through this scheme, compare one-way fixed check out test set and detect pivot mechanism, need not to reverse the position of pivot mechanism and can realize fixing big mount and little mount, need not to pull down pivot mechanism from check out test set and press again, the number of times that pivot mechanism installed on check out test set is once, and easy operation is convenient, is favorable to improving the efficiency that detects. In addition, by the scheme, the rotation detection of the large fixing frame is realized by directly pushing the first push rod, and compared with the detection of a one-way fixed detection device on the large fixing frame, the hand is not required to act on the large fixing frame, so that the bending of the large fixing frame caused by pushing the large fixing frame by the hand can be avoided, and the deformation of the large fixing frame after the detection is favorably ensured; and operations such as sleeving of the protection tube and the like are not needed, and the operation is simple and convenient.
Further, in the step A, if the small fixing frame is detected to have abnormal sound, the pivot mechanism is placed in a defective product box; if the big fixed frame is detected to have abnormal sound, the pivot mechanism is also put into a defective box. Therefore, unqualified pivot mechanisms to be detected are placed into the defective product box, the unqualified pivot mechanisms are convenient to classify, and subsequent processing is convenient.
Further, in the step A, if the small fixing frame is detected to have abnormal sound, a valve on the second push rod is opened; if the large fixing frame is detected to have abnormal sound, the valve on the first push rod is opened. From this, when abnormal sound appears in little mount or big mount, corresponding valve is opened to the accessible, lubricating oil can enter into the inlet port on first grip block or the second grip block under the pressure of force pump, directly oil for pivot mechanism's pivot, the lubrication to the pivot that has abnormal sound pivot mechanism in the testing process has been realized, in order to reduce the friction of big mount or little mount for the pivot, thereby get rid of the abnormal sound, need not to shift to pivot mechanism that has the abnormal sound and lubricate alone on other devices, and easy operation is convenient.
Further, before the pivot mechanism is placed in the detection device or taken down from the detection device, the first clamping block and the second clamping block are far away from each other. Therefore, the first clamping block and the second clamping block are far away from each other, so that the distance between the first clamping block and the second clamping block is increased, and the pivot mechanism is convenient to put on or take off the detection device.
Further, clamping mechanism is the screw, rotates the screw rod and makes the tip of screw rod support big mount or little mount tightly, and the reverse rotation screw rod makes the tip of screw rod loosen big mount or little mount. From this, through rotating the screw rod, can make the one end that the screw rod is arranged in the centre gripping groove offset big mount or little mount to realized the stable centre gripping to big mount or little mount, through the rotation of screw rod, realized the lateral shifting of screw rod in the centre gripping groove, and then can the centre gripping big mount or the little mount of different thickness, make the pivot mechanism of centre gripping groove can fix different specifications.
Further, the clamping mechanism is of a sliding block type, and the first sliding block is transversely pushed towards the direction close to the clamping groove, so that the abutting block abuts against the large fixing frame or the small fixing frame; and the second sliding block is pushed in the direction away from the first sliding block, so that the large fixing frame or the small fixing frame is loosened by the abutting block. From this, when needs support the piece and support big mount or little mount when tight, transversely promote first slider to the direction of being close to the centre gripping groove, first slider drives first latch and removes, the inclined plane of first latch skids on the inclined plane of second latch, thereby make and support the piece and remove to being close to big mount or little mount direction, support tight piece and support big mount or little mount tightly, after loosening first slider, first latch and second latch block each other, first slider can not reset under the effect of extension spring, compare the use through this scheme and rotate the screw rod from this, directly promote first slider lateral shifting can, need not to carry out the rotation operations, it is more convenient to operate, it is more handy. When the piece that will support when loosening big mount or little mount, upwards promote the second slider, the second slider extrudees the pressure spring, the second slider drives second latch rebound, second latch and first latch separation, the second latch no longer blocks first latch, first slider slides to the direction of keeping away from the centre gripping groove automatically under the effect of extension spring, first slider drives to support during the piece enters into horizontal chamber, support tight piece no longer to support tightly big mount or little mount, compare the use through this scheme and rotate the screw rod from this, directly upwards promote the second slider and can cancel and fix big mount or little mount, need not to carry out the rotation operations, it is more convenient to operate, it is more handy.

In addition, in the process of rotating the large fixing frame 1 and the small fixing frame 2 in the step a or the step B, if abnormal sound occurs, the corresponding valve 33 can be opened to supply oil for lubricating the rotating shaft 3. If in step B, abnormal noise occurs during the rotation of the large fixing frame 1, at this time, the valve 33 on the first push rod 30 can be opened by hand, the lubricating oil can enter the oil outlet pipe 34 under the pressure of the pressure pump 36 and enter the valve 33, and then enter the oil inlet hole of the first clamping block 4 from the valve 33 along the first oil inlet pipe 32, so as to oil the rotating shaft 3 of the pivot mechanism directly, thereby realizing the lubrication of the pivot mechanism with abnormal noise during the detection process, so as to remove the abnormal noise, and avoiding the need of putting the pivot mechanism with abnormal noise into a defective product box to transfer to other devices for independent lubrication, and the operation is simple and convenient.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make various changes and modifications without departing from the concept of the present invention, and these should be construed as the scope of protection of the present invention, which will not affect the effect of the implementation of the present invention and the utility of the patent. The techniques, shapes, and structural parts, which are omitted from the description of the present invention, are all known techniques.
