In the present invention, the front-back direction is a relative direction of the first electrical contact 31 and the second electrical contact 32, wherein the direction of the first electrical contact 31 is a front direction.
In the technical scheme of the invention, when the workpiece moves to the checking fixture 100, the workpiece contacts with the abutting part 22, the workpiece pushes the test piece 20 to move in the forward and backward directions, the third electrical contact 23 arranged on the abutting part 21 is also driven to move in the forward and backward directions, and in the moving process, the third electrical contact 23 abuts against the first electrical contact 31 or the second electrical contact 32, so that the circuit structure is conducted, and then the alarm device 70 is electrified to give an alarm when the workpiece is unqualified in size. The checking fixture 100 provided by the invention can be arranged on other equipment for transporting and positioning the workpieces, so that the size of each workpiece can be monitored in real time in the production process of the workpieces, the monitoring hysteresis is greatly reduced, and the waste is reduced.
As for the alarm device 70, the alarm device 70 is a common alarm device 70, and the specific structure of the alarm device 70 is not particularly limited as long as an alarm can be realized. In this embodiment, the alarm device 70 is configured as a speaker, and when the circuit structure is powered on, the speaker makes a sound to prompt the user that the workpiece is unqualified.
Further, the pushing part 22 is used for being pushed and driving the third electrical contact 23 to move backwards to the second alarm position when the workpiece is too long; the detection tool 100 further comprises a resetting piece, the resetting piece is connected with the testing piece 20, and the resetting piece is used for resetting the testing piece 20 to the first alarm position.
Referring to fig. 1, in this embodiment, when the workpiece reaches the testing position, the workpiece contacts with the abutting portion 22 and abuts against the abutting portion 22 to move backward, and at this time, when the workpiece is too long, the abutting portion 22 is pushed farther, so that the testing piece 20 reaches the second alarm position, an alarm is triggered, and the too long workpiece is eliminated; when the workpiece is too short, the workpiece does not contact the pushing part 22, so that the test piece 20 does not displace at the first alarm position, and an alarm can be triggered to eliminate the too short workpiece. Therefore, defective products can be detected in time by detecting the workpieces in the production and transportation of the workpieces, and excessive waste is prevented. After one workpiece is tested, the testing part 20 needs to be reset to the first alarm position, and the subsequent workpieces can continue to be normally tested, so that the resetting part is arranged and can reset the testing part 20 to the first alarm position.
Furthermore, the testing fixture 100 further includes a surface difference meter 50, the surface difference meter 50 includes a measuring rod 51 movably disposed along the front-back direction, the measuring rod 51 constitutes the testing piece 20, and a zero position of the measuring rod 51 is preset on the surface difference meter 50, so that the measuring rod 51 is reset to the zero position; when the test piece 20 is located at the first alarm position, the position of the corresponding measuring rod 51 is the return-to-zero position, so that when the measuring rod 51 is reset to the return-to-zero position, the test piece 20 is driven to move to the first alarm position.
In this embodiment, the reset unit is the surface difference meter 50, in this embodiment, the test unit 20 is configured by using the measuring rod 51 movably disposed in the surface difference meter 50 in the front-back direction, the surface difference meter 50 can be set to a zero position for performing a test in normal use, and in this embodiment, the reset effect of the zero position on the measuring rod 51 is used to reset the test unit 20. The test piece 20 can therefore be reset to the first alarm position as long as the corresponding position of the measuring rod 51 is set to the zero position when the test piece 20 is in the first alarm position.
Regarding the reset member, in this embodiment, the reset member adopts the surface difference meter 50 and performs reset by using the reset function of the surface difference meter 50 itself. This does not mean that the resetting member is only the surface difference meter 50, the resetting member may be a spring 34, the resetting of the testing member 20 can be realized by the spring 34 elastically pressing the testing member 20 at the first alarm position, and the resetting member may be a magnet disposed at the first alarm position, the magnet can reset the testing member 20 to the first alarm position by virtue of an attractive force, that is, the resetting member only needs to be capable of resetting the testing member 20 to the first alarm position.
Further, the detecting tool 100 further comprises: a power supply 60, a sensor and a controller, the power supply 60 being electrically connected to the first circuit structure; the sensor is arranged on the base 10 and is used for triggering a detection signal when sensing that the workpiece is close to the pushing part 22; the controller is electrically connected with the sensor and the power supply 60 respectively, and the controller is used for controlling the power supply 60 to be turned on when receiving the detection signal.

Thus, when the workpiece is not detected, the testing part 20 is located at the first alarm position, but the alarm device 70 does not alarm, so that the power loss can be reduced, and the false alarm of the alarm device 70 can be reduced.
Further, the inspection device 100 further includes two conductive rods 30 sequentially arranged on the base 10 at intervals in the front-back direction, the conductive rods 30 extend in the front-back direction, the first electrical contact 31 and the second electrical contact 32 are respectively arranged at two ends of the two conductive rods 30 close to each other, and the two conductive rods 30 are elastically arranged on the base 10 to limit the displacement of the test piece 20.
In this embodiment, the first electrical contact 31 and the second electrical contact 32 are respectively disposed on the two conductive rods 30, and the two conductive rods 30 are elastically disposed on the base 10, so that when the test piece 20 contacts with the first electrical contact 31 and the second electrical contact 32, the impact force can be weakened by the elastic arrangement of the conductive rods 30, and therefore, when the test piece 20 repeatedly uses the test tool 100, the test piece 20 does not contact with the first electrical contact 31 and the second electrical contact 32 to cause a reduction in test accuracy, thereby playing a certain role in buffering protection.
Specifically, the base 10 is at least convexly provided with two mounting seats 40, and the mounting seats 40 are sequentially arranged at intervals in the front-back direction; the two conducting rods 30 are respectively arranged on different installation seats 40 in a penetrating mode, limiting parts 33 are arranged on the conducting rods 30 in a protruding mode along the circumferential direction of the conducting rods, a spring 34 is sleeved on each conducting rod 30, one end, close to the abutting part 21, of each spring 34 abuts against the limiting part 33, the other end of each spring 34 abuts against the installation seat 40, and therefore displacement of the conducting rods 30 is limited.
In this embodiment, the specific manner of the elastic arrangement of the conductive rod 30 is to provide a spring 34, the conductive rod 30 is provided with a limiting portion 33 along the circumference, and the spring 34 is disposed between the limiting portion 33 and the mounting seat 40, so that when the conductive rod 30 collides with the testing piece 20, the conductive rod 30 is displaced, and the spring 34 is compressed under stress and exerts a repulsive force on the testing piece 20, thereby achieving the effect of buffering and protecting the testing piece 20, and also preventing the testing piece 20 from lowering the testing precision due to the contact with the first electrical contact 31 and the second electrical contact 32.
Regarding the specific implementation manner of the elastic arrangement of the conductive rod 30, in the present embodiment, the conductive rod 30 is elastically arranged by the elastic force of the spring 34. This does not mean that the conductive rod 30 only depends on the spring 34, and the restoring member may also be buffered by other elastic materials, for example, an elastic material is filled near the conductive rod 30, and the elastic material is used for buffering, that is, the conductive rod 30 only needs to buffer the collision of the test piece 20 to a certain extent.
Still further, at least one of the first electrical contact 31 and the second electrical contact 32 is an adjustable electrical contact movably disposed in a front-back direction, so that a distance between the first electrical contact 31 and the second electrical contact 32 is adjustable during the movement of the adjustable electrical contact.
In this embodiment, at least one adjustable electrical contact is disposed between the first electrical contact 31 and the second electrical contact 32, and the adjustable electrical contact is movably disposed in the front-back direction, so that the distance between the first electrical contact 31 and the second electrical contact 32 is adjustable. The distance between the first electrical contact 31 and the second electrical contact 32 is actually an error in the production of the workpiece, and when the error can be adjusted, the checking fixture 100 provided by the invention can be used for detecting more checking fixtures 100 with different errors, so that the checking fixture 100 provided by the invention has wider applicability.

But it does not mean that the adjustable contact is only adjusted by a ball screw, the base 10 may also provide different positions for the movable seat by arranging a plurality of mounting points at intervals from front to back, so as to adjust the position of the movable seat, and the movable seat may be adjusted as long as the position of the movable seat can be adjusted in the front-back direction.
Specifically, the base 10 is made of an insulating material.
