Description
Technical Field
The utility model belongs to the technical field of weldment measurement, and particularly relates to a device for rapidly measuring friction quantity of a friction welding weldment.
Background
The stepped shaft friction welding parts are widely applied in the industrial field, and when the friction welding process is formulated, the friction amount under various welding processes needs to be rapidly determined so as to carry out comparative analysis, and meanwhile, the friction amount is accurately mastered, so that the practical significance for reducing the loss of welding materials and the production cost is very important. However, the current friction calculation generally adopts a vernier caliper to measure the total length of the components before welding (also called the length before welding) and the length after welding respectively, and the length after welding is subtracted from the length before welding to obtain the friction. Therefore, the rapid measurement of the friction quantity of the friction welding piece has extremely important practical significance and engineering application value.
The ultrasonic method is one of five conventional nondestructive testing methods, and the advantage of rapid thickness measurement is obvious. However, in actual measurement, it is found that when the length of the friction-welded part is directly measured from any one of the left and right end faces of the part by the ultrasonic method, the measurement error is slightly larger. The analysis shows that the reason is mainly caused by the fact that the size of the end face of the small end of the friction welding piece is smaller than the diameter of the piezoelectric wafer of the ultrasonic straight probe. In addition, during measurement, a detection person needs to hold the friction welding piece with one hand and operate the ultrasonic equipment with the other hand to perform measurement, and labor intensity is high. Therefore, the device for rapidly measuring the friction quantity of the friction welding piece based on the ultrasonic method is very necessary, the small end surface contact between the ultrasonic straight probe and the friction welding piece can be converted into the large plane contact, the detection speed and the detection precision can be improved, one hand of a detector can be liberated, and the labor intensity of the detector can be greatly reduced.

Detailed Description
In order to make the purpose and technical solution of the present invention clearer, the present invention is further described with reference to the accompanying drawings and specific embodiments. The present embodiment is merely to explain the present invention, and the content thereof is not limited.
As shown in fig. 1-3, a device for rapidly measuring friction amount of friction welding parts comprises a bottom plate 1 and a vertical plate 3, wherein the end parts of the bottom plate and the vertical plate are vertically connected, and the vertical plate 3 is vertically connected with a spring fixing plate 5 in a sliding manner through a sliding chute 31; a cover plate 8 connected through a spring 6 is arranged in parallel below the spring fixing plate 5.
The sliding groove 31 formed in the vertical plate 3 facilitates adjustment of the vertical position of the spring fixing plate 5 so as to adapt to friction welding parts with different lengths.
Furthermore, the vertical plate 3 is provided with a positioning bolt 4 on the chute 31 to be connected with the spring fixing plate 5.
Further, the spring fixing plate 5 is provided with a screw hole 51 at a connection portion with the slide groove 31 to be connected with the positioning bolt 4.
Furthermore, a spring 6 is respectively arranged at the left end and the right end of the spring fixing plate 5 and is connected with the cover plate 8.
Further, the spring fixing plate 5 is provided with a blind hole 52 for mounting the spring positioning pin 7, and the end of the spring 6 is sleeved on the spring positioning pin 7 through the cotter pin 11.
Further, the spring positioning pin 7 and the blind hole 52 form an interference fit.
Further, the bottom plate 1 and the vertical plate 3 are fixedly connected through an inner hexagonal bolt 2.
During measurement, a worker firstly pushes and presses the spring 6 on the cover plate 8, the friction welding piece 10 is placed between the bottom plate 1 and the cover plate 8, and the cover plate 8 automatically clamps the friction welding piece 10 under the elastic force action of the spring 6. Then, a measuring person coats a couplant on the upper surface of the cover plate 8, and places the ultrasonic straight probe 9 above the position where the cover plate 8 and the friction welding piece 10 are pressed, so that the small end surface contact between the ultrasonic straight probe 9 and the friction welding piece 10 is changed into large plane contact. After the calibration of the ultrasonic straight probe 9 is completed, the distances from the upper surface of the cover plate 8 to the lower surface of the cover plate 8 and the upper surface of the base plate 1 are respectively measured, and the length (or the length after welding) of the friction welding piece 10 is obtained by subtracting the former from the latter. The overlapping length of the friction welding parts before welding and the length after welding of the friction welding piece 10 are measured according to the steps, and the difference between the overlapping length and the length after welding is the friction quantity. If the friction welding piece 10 is too long or too short, the positioning bolt 4 can be unscrewed, the spring fixing plate 5 can move up and down along the sliding groove 31, and the positioning bolt 4 is screwed after the adjustment is in place, so that the measurement of the length and the friction quantity of the friction welding piece 10 in a large size range is realized.
The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered by the protection scope of the utility model.
