Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to an axial force measurement probe, and more particularly to an axial force measurement probe equipped with a detachable mechanism for measuring axial force using ultrasonic waves. is there.

[Prior Art] Conventionally, in the axial force measuring probe of this type, as shown in FIGS. 5 to 7, the substrates 41 and 42 of the mounting spring member 40 arranged near the side surfaces of the sensor 20 which are not adjacent to each other.
The protrusions 41a, 42a were formed by bending outwardly with respect to a part of the above. As a result, the substrates 41 and 42 of the mounting spring member 40 are pressed and grasped by fingers to reduce the distance between the protrusions 41a and 42a, and the protrusions 41a and 42a are engaged in the groove 2 of the bolt 1. After that, the mounting spring member 40 was pressed and moved in the direction of the bottom 2a of the groove 2 while holding the mounting spring member 40, and the protrusions 41a and 42a were locked to the locking grooves 2b and 2c on the peripheral surface of the groove 2. In this state, the sensor 20 is pressed against the bottom 2a by the pressing spring 30, and appropriate measurement is performed. After the end of the measurement, the mounting spring member 4
No. 0 substrate 41, 42 is pressed and grasped by fingers and the protruding portion 1
By making the distance between 4a and 42a narrow and moving in a direction away from the bottom 2a, the projections 41a and 42a are disengaged from the locking grooves 2b and 2c, and as a result, the axial force measuring probe from the groove 2 of the bolt 1 is obtained. I had removed 10.

[Problems to be Solved by the Invention] However, in the conventional axial force measurement probe, it is necessary to press the substrates 41 and 42 of the attachment spring member 40 with fingers each time when the bolt 1 is attached to or removed from the groove. The operation was extremely complicated.

[Means for Solving the Problems] To this end, the present invention proposes that "a part of a base plate of a mounting spring member that is respectively disposed near side surfaces of a sensor that transmits and receives ultrasonic waves is not adjacent to each other. In an axial force measuring probe that is engaged in a stop groove, the base plate of the mounting spring member is cut and raised outward, and the free end is engaged in the locking groove by pressing the groove portion toward the bottom. Forming a mounting spring, and forming a window portion arranged in the vicinity of the base plate of the mounting spring member to press the mounting spring inward by moving in a direction away from the bottom portion of the groove portion so as to separate from the locking groove. The conventional problem is solved by the "axial force measuring probe characterized by including the removed member."

[Operation] In the axial force measuring probe of the present invention, the mounting spring formed by cutting and raising the base plate of the mounting spring member presses the mounting spring in the direction approaching the bolt, and engages with the locking groove of the groove portion. Along with the movement of the detaching member in the direction of separating, the mounting spring is pressed inward to be disengaged from the locking groove.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 10 denotes an axial force measuring probe of the present invention, which is arranged at the tip portion and which transmits an ultrasonic wave and receives a reflected wave of the ultrasonic wave reflected by a target object, and the sensor 20 is a pressing spring 30. And mounting springs 43 and 44 which are attached to one surface of the bridging portion 40a via the substrate and are cut and raised outward from the substrates 41 and 42 which are respectively disposed near the side surfaces of the sensor 20 which are not adjacent to each other. The mounting spring member 40, the shaft body 50 having one end fixed to the other surface of the bridging portion 40a of the mounting spring member 40, and the screw portion 51 formed from the central portion toward the other end, A detachable member that includes substrates 63 and 64 that are arranged near the substrates 41 and 42 of the spring member 40 and that have windows 61 and 62 through which the attachment springs 43 and 44 are inserted, respectively. 0, the detachment members 60 bridge 6
0a, one end of which is fixed to one surface of the shaft body 50, and the shaft body 50 is inserted through the through hole 71 extending in the axial direction, and the threaded portion 51 of the shaft body 50. Is disposed between the attachment gripping member 80 having the screw portion 82 of the screw threaded thereinto, and the removal gripping member 70 and the attachment gripping member 80, and one end of the attachment gripping member 80 abuts on the step 71a of the through hole 71 and the other. The pressing spring member 90 has an end abutting against the step 81a of the through hole 81. The mounting springs 43, 44 are cut and raised from the front side in the mounting direction toward the rear side in the mounting direction, and further, in the rear side in the mounting direction, the window portions 61, 61 of the removing member 60.
It is projected outward from 62. An appropriate driving device (not shown) is connected to the sensor 20 via an electric wire 21.

First, an appropriate contact medium such as water, oil, or glycerin is applied to the bottom 2a of the groove 2 of the bolt 1.

Next, the mounting gripping member 80 is gripped by fingers, and the tip of the axial force measuring probe 10 is inserted into the groove 2 of the bolt 1.
At this time, since the free ends of the mounting springs 43 and 44 are wider than the width of the groove 2, they are locked to the edge of the groove 2 (see FIG. 3 (a)).

After that, when the mounting gripping member 80 is pressed toward the bottom portion 2a of the groove portion 2, the free ends of the mounting springs 43 and 44 are pushed into the groove portion 2 and the sensor 2 is brought into contact with the bottom portion 2a, and then the inner peripheral surface thereof. Are engaged in the locking grooves 2b, 2c of the (Fig. 3 (b)
reference). In this state, the mounting spring member 40 is fixed to the groove portion 2 even if the fingers are removed from the mounting grip member 80, so that the sensor 20 is pressed by the pressing spring 30 into the bottom portion 2a of the groove portion 2.
Is pressed against (see FIG. 3 (b)).

After performing a desired measurement by an appropriate driving device (not shown), the detachable grip member 70 is gripped by fingers and moved in the direction of the attachment grip member 80 against the pressing spring member 90. As a result, the edge portions of the window portions 61, 62 of the removal member 60 press the mounting springs 43, 44 inward, so that the locking grooves 2b, 2c.
From the free ends of the mounting springs 43 and 44 (3rd
(See Figure (c)). At this time, since the pressing spring member 90 presses the mounting gripping member 80 in the direction away from the bolt 1, the mounting springs 43 and 44 are separated from the groove 2 and the sensor 20 is also separated from the bottom portion 2a.

Finally, the tip of the axial force measuring probe 10 may be removed from the groove 2 of the bolt 1.

[Advantages of the Invention] As is apparent from the above, the present invention has a structure in which a part of the base plate of the mounting spring member disposed near the side surfaces of the sensor that transmits and receives ultrasonic waves is not engaged with the locking groove on the circumferential surface of the groove portion of the bolt. In the axial force measuring probe, the base plate of the mounting spring member is cut and raised outward, and the free end is pressed into the locking groove toward the bottom portion of the mounting spring. And a window portion formed in each of the mounting spring members near the base plate for pressing the mounting spring inward by moving the mounting spring member in a direction away from the bottom portion of the mounting spring member to disengage from the locking groove. Since it includes the detachable member, it has the effect of facilitating attachment / detachment of the bolt to / from the groove portion and improving workability.
