DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a shot peening machine provided with a peening intensity measuring device for electrically measuring the peening intensity of a shot shot.

[0002]

2. Description of the Related Art As disclosed in Japanese Patent Application Laid-Open No. Hei 4-19071, the amount of kinetic impact (also kinetic energy) of a shot shot and the number of impact particles of the shot are captured, and peening by the shot shot is performed. The applicant has previously proposed a sensor for electrically measuring the intensity. And, as disclosed in Japanese Patent No. 2766463, this sensor is provided between a nozzle for ejecting a shot and a product, a shot peening machine disposed so as to be able to enter and exit, and disclosed in Japanese Patent Application Laid-Open No. Hei 4-332836. As described above, the applicant has also proposed a shot peening machine which is disposed between a product and a centrifugal projector for centrifugally projecting a shot.

[0003]

However, in the conventional shot peening machine configured as described above, the sensor hinders the projected shot from hitting the product normally, reducing the shot peening effect. Further, in order to solve the problem, it is necessary to increase the space, and further, since a separate device for moving the sensor is required, there is a problem that the shot peening machine becomes complicated and large-scale.

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a shot peening machine that does not require a sensor to be separately inserted between a shot projecting device and a product.

[0005]

In order to achieve the above object, a shot peening machine according to the present invention is constructed as shown in FIG.
Has a sensor 1 and a controller 2 as shown in FIG.
In a shot peening machine equipped with a peening intensity measuring device for electrically measuring the peening intensity of a shot shot, the sensor 1 is incorporated in a product holding means or a pseudo product, and the controller 2 is connected via a communication device 3. Characterized in that it is connected to

As shown in FIG. 1, the sensor 1 includes a detecting unit 4 for detecting a shot collision intensity, and a processing circuit 5 for electrically processing the shot collision intensity received by the detection unit 4. It consists of The controller 2
Is represented by a microcomputer,
It has an arithmetic circuit 6 and a monitor 7. Further, the communication device 3 includes a transmission device 8 and a reception device 9, and includes a transmission / reception device using a slip ring and a wireless transmission / reception device using wireless.

[0007] With the above-mentioned structure, the product holding means or the pseudo product is appropriately moved and the detecting unit 4 of the sensor 1 is moved.
When the shot is hit, the detection unit 4
Generates an elastic wave, which is generated by the processing circuit 5 of the sensor 1.
The electronically processed signal is then input to the controller 2 via the communication device 3 and displayed on the monitor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment to which the present invention is applied will be described in detail with reference to FIGS. However, those having the same functions as those described with reference to FIG. 1 described above are diverted and description thereof is omitted. In an apparatus to which the transmission / reception device 10 using a slip ring is applied as the communication device 3 described above, as shown in FIG.
The above-mentioned sensor 1 is built in, and the sensor 1 is electrically connected to the microcomputer 12 as the above-mentioned controller 2 via the transmitting / receiving device 10.

[0009] In the device configured as described above, when the product holding means 11 holding the product W is moved up and down as appropriate to hit the detection unit 4 of the sensor 1, the detection unit 4 generates an elastic wave due to the collision of the shot. The generated elastic waves are electrically processed by the processing circuit 5 of the sensor 1, and then the processed signals are input to the microcomputer 12 via the transmission / reception device 10 and are displayed by display means such as a CRT. Will be displayed.

[0010] Further, in an apparatus to which a wireless transmission / reception device 30 by radio is applied as the communication device 3, as shown in FIG. 3, the sensor 1 is incorporated in the product holding means 21, and It is electrically connected to the microcomputer 22 as the above-described controller 2 via the transmitting / receiving device 30.

With the above-described structure, when the product holding means 11 holding the product W is moved up and down as appropriate to hit a shot on the detecting section 4 of the sensor 1, the shot collision occurs in the same manner as described above. The detection unit 4 generates an elastic wave,
This elastic wave is electrically processed by the processing circuit 5 of the sensor 1, subsequently input to the microcomputer 22 via the wireless transmission / reception device 30, and displayed by the display means.

Although the sensor 1 is incorporated in the product holding means 11 and 21 in the above-described embodiment, it is a matter of course that the same effect can be obtained by incorporating the sensor 1 in a pseudo product. The product holding means 11 and 21 include a moving table on which products are placed, a set jig for setting products, and the like.

[0013]

As is apparent from the above description, the present invention relates to a shot peening machine including a sensor and a controller, which is provided with a peening intensity measuring device for electrically measuring the peening intensity of a projected shot. Is built into the product holding means or the pseudo product, and connected to the controller via a communication device, so that there is no need to separately put a sensor between the shot projecting device and the product, and the structure is simple. It has excellent practical effects such as.
