In order to solve the technical problems in the prior art, the utility model provides a rivet installation detection device which is used for detecting workpieces. As shown in fig. 1 to 4, the rivet setting detection device includes:
the mounting plate 1 is provided with at least one through hole 2, and the aperture of the middle part of the through hole 2 is larger than the aperture of the end parts at the two ends of the through hole;
a probe 3 disposed in the through hole 2 and movably connected to the mounting plate 1 in a first direction; the probe 3 comprises a rod portion 31 and a protruding portion 32, two ends of the rod portion 31 penetrate through two ends of the through hole 2 respectively, the protruding portion 32 protrudes outwards in the direction away from the center of the through hole 2, the diameter of the protruding portion 32 is larger than that of the end portion of the through hole 2, and the protruding portion 32 is used for limiting the moving position of the probe in the first direction, so that the probe 3 is always located in the through hole 2. Here, the first direction is the up-down direction as viewed from the paper surface, and therefore here the protrusion 32 can restrict the movement of the probe 3 in the up-down direction of the through hole 2.
When the detection device provided by the embodiment of the utility model is used for detecting the rivet installation position, the probe 3 is moved in the up-down direction, the first end of the rod part 31 is abutted against the rivet hole position of the workpiece, and the position installation condition of the rivet can be confirmed by observing the length of the second end of the probe 3 extending out of the through hole. For example, when the rivet of the workpiece is installed correctly, the probe is moved to enable the first end of the probe to be abutted with the rivet on the workpiece, and the second end of the probe extends out of the first length; when the rivet of the workpiece is incorrectly installed, for example, the rivet hole is obliquely protruded, the probe is moved to enable the first end of the probe to be abutted with the rivet on the workpiece, and the rivet is not installed in place, the rivet hole is protruded, and then the second end of the probe extends out of the second length; when no rivet is arranged in the rivet hole on the workpiece, the second end of the probe enters the rivet hole of the workpiece when the probe is moved, and the second end of the probe extends out of the third length; the relationship of the extension lengths in the three states is as follows: the second length > the first length > the third length. The detection method is only illustrative and not limited thereto.
Through removing the probe, remove the rivet position department of probe to the work piece, when the first end of probe can't remove, the second end of probe stretches out the length of through-hole can confirm the installation situation of rivet, and this detection device is simple, convenient operation, for operating personnel provides convenience, can improve detection efficiency, reduces human cost.
With continued reference to fig. 1 to 4, the detection device further includes a probe 4 disposed at the second end of the rod portion 31, where the probe 4 is fixedly connected to the rod portion 31 by a screw. The probe 4 is provided to extend the length of the second end of the shaft 31 extending out of the through hole 2, so that an operator can conveniently measure and observe the extending length of the second end of the shaft 31 extending out of the through hole 2 during detection.
Further, the detection device further comprises a guide sleeve 5, the guide sleeve 5 is arranged in the two ends of the through hole 2, the guide sleeve 5 is a cylindrical member with a hollow inside, the probe 3 is arranged in the guide sleeve 5 and is movably connected with the guide sleeve 5, and the guide sleeve 5 enables the probe to move up and down accurately and smoothly.
Further, the detecting device further includes an elastic member disposed at an intermediate portion of the through hole 2, and the probe 3 moves in the first direction; when the probe 3 moves in the first direction, one end of the elastic member may abut against one end of the protruding portion 32 away from the workpiece. The elastic member ensures that the probe moves downward in the through hole. In this embodiment, the elastic member is a spring 6.
Further, the detection device also comprises a proximity switch sensor 7 arranged on the mounting plate 1 to detect the position of the probe 4. The proximity switch sensor is fixed, the position of the probe moves along with the installation condition of the rivet on the workpiece, and the installation condition of the rivet can be tested according to the relative movement position of the probe relative to the proximity switch sensor.
Further, the probe 4 is a cylinder with a step, the cylinder is provided with a middle concave structure, in a state that the rivet mounting position of the workpiece is correct, the proximity switch sensor 7 is opposite to the concave structure, that is, when the position of the proximity switch sensor 7 is flush with the concave structure, the rivet is mounted at the correct position in this state. The structural arrangement of the probe 4 is only illustrated here by way of example and is not limited thereto.
When the detection device provided by the embodiment of the utility model is used for detecting the rivet installation position, the probe 3 is moved in the up-down direction, the first end of the rod part 31 is abutted against the rivet hole position of the workpiece, and the proximity switch sensor can confirm whether the rivet exists in the rivet or not and the installation condition of the rivet by judging the probe arranged at the second end of the probe 3. For example, when the rivet of the workpiece is installed correctly (as shown in fig. 2), the probe is moved to enable the first end of the probe to be abutted against the rivet on the workpiece, the second end of the probe extends out of the first length, the middle concave part of the probe 4 is in height consistency with the proximity switch sensor, the sensor cannot obtain a signal, and the position of the rivet is judged to be normal; when the rivet of the workpiece is installed incorrectly (as shown in fig. 3), for example, when the rivet hole is obliquely protruded, the probe is moved to enable the first end of the probe to be abutted against the rivet on the workpiece, and the rivet is not installed in place, the rivet hole is protruded, at the moment, the second end of the probe extends out of the second length, the protruded part of the lower part of the probe 4 is consistent with the height of the proximity switch sensor, the sensor obtains a signal, and the position of the rivet is judged to be abnormal; when no rivet is arranged in the rivet hole on the workpiece (as shown in fig. 4), the second end of the probe enters the rivet hole of the workpiece when the probe is moved, the second end of the probe stretches out of a third length, the height of the protruding part at the upper part of the probe 4 is consistent with that of the proximity switch sensor, the sensor obtains a signal, and the position of the rivet is judged to be abnormal; the relationship of the extension lengths in the three states is as follows: the second length > the first length > the third length. The detection method is only illustrative and not limited thereto.
Optionally, the detection device further comprises a detection rod disposed on the mounting plate 1 to detect the position of the probe 4.
The working principle of the rivet setting detection device according to the present utility model will be described in detail below using a dual mass flywheel as an example of a detection workpiece. As shown in fig. 1 and 3, the detection device has eight sets of probes and proximity switch sensors, which detect the mounting states of eight rivets on the workpiece, respectively.
As shown in fig. 2, when the rivet 9 of the dual mass flywheel 8 is installed in a correct position, the first end of the probe 3 abuts against the rivet at the rivet hole position, and the proximity switch sensor 7 is opposed to the recessed structure on the probe 4.
As shown in fig. 3, when the interior of the dual mass flywheel 8 is free of rivets 9, the first end of the probe 3 will drop into the rivet hole where the rivet 9 is mounted, at which point the upper protruding section of the probe 4 will drop flush with the top of the proximity switch sensor 7.
As shown in fig. 4, when the mounting position of the internal rivet 9 of the dual mass flywheel 8 is incorrect, the rivet 9 is protruded into the rivet hole, the first end of the probe 3 is abutted on the rivet at the position of the rivet hole, and at this time, the lower protruded section of the probe 4 is lifted to be flush with the proximity switch sensor 7.
In order to improve the detection accuracy, a precise proximity switch sensor can be selected, and when the distance between the proximity switch sensor 7 and the probe 4 is within the sensing distance (for example, less than 1 mm), an indicator light on the proximity switch sensor is on; and when the distance between the proximity switch sensor and the probe 4 is larger than the sensing distance, the indicator light on the proximity switch sensor is not on. The illumination or non-illumination of the indicator light on the proximity switch sensor may represent either an incorrect or correct two-state of rivet position installation.
When the rivet 9 is installed at the correct position, as shown in fig. 2, the head of the proximity switch sensor is opposite to the concave structure of the probe 4, the distance between the proximity switch sensor and the probe 4 is relatively large, and the proximity switch sensor is larger than the sensing distance, the sensor cannot obtain sensing signals, the indicator lamp on the sensor is not on, the indicator lamp is not on, the rivet 9 can be installed in the dual-mass flywheel 8, and the rivet 9 is installed at the correct position.
As shown in fig. 3, when there is no rivet in the dual-mass flywheel 8, the position of the probe 4 is lowered, the relative distance between the head of the proximity switch sensor and the probe 4 is smaller and smaller than the sensing distance, the sensor senses the sensing signal, and when the indicator lamp on the sensor is on, the on of the indicator lamp can represent that there is no rivet 9 in the dual-mass flywheel or that the rivet 9 is not in the proper position.
As shown in fig. 4, when the rivet 9 in the dual-mass flywheel 8 is not at the correct position, the probe 4 is lifted up, the distance between the head of the sensor and the probe 4 is still smaller than the sensing distance, and after the sensor senses the sensing signal, the indicator light on the sensor is on, and the on of the indicator light can represent that no rivet 9 or no rivet 9 is at the proper position in the dual-mass flywheel 8.
The rivet installation detection device provided by the utility model has the following advantages:
through removing the probe, remove the rivet position department of probe to the work piece, when the first end of probe can't remove, proximity switch sensor can confirm whether there is the rivet in the rivet hole through judging the probe of installing at the probe second end to and the installation status of rivet, this detection device is simple, convenient operation, for operating personnel provides convenience, can improve detection efficiency, reduces the human cost.
The foregoing is a further detailed description of the utility model in connection with the preferred embodiments, and it is not intended that the utility model be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the utility model, and these should be considered to be within the scope of the utility model.
