[0009] Preferably, a sounding block is positioned and installed on the top front side of the body, and a striking block is correspondingly placed on the top of the sounding block, and the striking block is located on the top outer side of the body.

[0010] Preferably, a mounting plate is screwed on the top front side of the body, and a rotating shaft is rotatably mounted through an internal slot in the mounting plate, and a striking block is mounted through the front end of the rotating shaft, and the striking block is arc-shaped.

[0011] Preferably, a transmission gear is installed through the rear end of the rotating shaft, and a cylinder is correspondingly mounted on the top of the transmission gear.

[0012] Preferably, the bottom inner side of the cylinder is grooved with a row of toothed blocks, the row of toothed blocks are evenly spaced, and the bottom of the row of toothed blocks is meshed with a transmission gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) A cylinder is installed on the top left side of the machine body. A detection head is installed at the outer end of the cylinder. At the same time, a copper part body is installed on the inner side of the product at the outer end of the detection head. The cylinder can be started by starting the switch to drive the detection head to squeeze the copper part body inside the product. After the cylinder drives the detection head to be pulled out and reset, if the copper part body is still inside the product, the product is qualified. If the copper part body is not inside the product, the product is unqualified. This simplifies the operation steps and makes it more practical.

[0015] (2) Furthermore, a placement seat is installed on the upper right side of the machine body, and the product is placed in a groove inside the placement seat. The placement seat can be used to position the product after placement, so as to avoid misalignment or displacement of the product during subsequent testing and improve the testing stability of the product.

At the same time, a striking block and a transmission gear are installed through the front and rear ends of the rotating shaft, respectively. When the transmission gear rotates, the striking block installed at the front end of the rotating shaft can automatically strike the sounding block to produce a sound, which is more practical.

[0018] (5) Furthermore, a row of toothed blocks is set at equal intervals in the groove on the inner side of the bottom of the cylinder, and a transmission gear is meshed at the bottom of the row of toothed blocks. When the cylinder drives the detection head to test the product, the row of toothed blocks drives the transmission gear to rotate in the forward direction, thereby automatically tapping the rattle block to make a sound. Conversely, when the cylinder drives the detection head to be pulled out and reset, the rattle block can also be automatically tapped to make a sound. This can remind the staff to pay attention to the test results before and after the test, thus improving the testing efficiency of the riveting test fixture. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides the following technical solution:

[0029] Example 1: To address the problem that existing testing procedures are cumbersome, reducing the efficiency of riveting inspection of product 14, increasing the workload of staff, and having poor practicality, the following is disclosed: a machine body 1 and a pneumatic valve 7, wherein the pneumatic valve 7 is positioned on the upper left side of the machine body 1, and the pneumatic valve 7 is sealed to a cylinder 5 via an air pipe; a start switch 2 and a stop switch 3 are respectively provided on both sides of the front end of the machine body 1, and the start switch 2 and the stop switch 3 are symmetrically arranged about the vertical center line of the machine body 1, and the start switch 2 and the stop switch 3 are connected to the cylinder 5 via a wiring harness; the cylinder 5 is installed on the top left side of the machine body 1 by screws, and a detection head 6 is provided on the outer end of the cylinder 5, and a copper body 8 is corresponding to the outer side of the detection head 6.

[0030] A placement base 4 is positioned and installed on the top right side of the body 1, and the product 14 is placed in the slot inside the placement base 4, and the product 14 is in close contact with the placement base 4; a copper body 8 is provided inside the product 14.

[0031] like Figures 1-5 As shown, before performing the riveting test on product 14, product 14 is placed inside the placement seat 4 for locking and limiting, which prevents product 14 from becoming loose, misaligned, or shifting during the test, thus improving the test stability of product 14. Then, the cylinder 5 is activated by the start switch 2 to drive the detection head 6 to perform a compression test on the copper body 8 set inside product 14. At the end of the test, the cylinder 5 is activated by the stop switch 3 to drive the detection head 6 to be pulled out and reset. If the copper body 8 is still inside product 14, product 14 is qualified; if the copper body 8 is not inside product 14, product 14 is unqualified. This not only simplifies the operation steps but also reduces the workload of the staff, making it more practical.

[0032] Example 2 differs from Example 1 in that the sound emitted by the sound block 12 before and after the test can remind the staff to pay attention to the test results in a timely manner, thereby improving the testing efficiency of the riveting test fixture. The invention discloses that: a sound block 12 is positioned and installed on the top front side of the machine body 1, and a striking block 11 is correspondingly located on the top of the sound block 12; the striking block 11 is located on the top outer side of the machine body 1; a mounting plate 13 is screwed on the top front side of the machine body 1, and a rotating shaft 10 is rotatably mounted through the internal slot of the mounting plate 13; the striking block 11 is rotatably mounted through the front end of the rotating shaft 10, and the striking block 11 is arc-shaped; a transmission gear 9 is rotatably mounted through the rear end of the rotating shaft 10, and a cylinder 5 is correspondingly located on the top of the transmission gear 9; a row of toothed blocks 15 is provided in the slot on the bottom inner side of the cylinder 5, and the row of toothed blocks 15 is evenly spaced, with the transmission gear 9 meshing at the bottom of the row of toothed blocks 15.

[0033] like Figures 1-7As shown, when the cylinder 5 drives the detection head 6 to perform a compression test on the copper body 8 inside the product 14, the cylinder 5 pushes the detection head 6 to extend and move, while simultaneously driving the transmission gear 9 to rotate forward through a row of toothed blocks 15. At this time, the forward rotating transmission gear 9 will drive the striking block 11 installed at the front end of the rotating shaft 10 to reciprocate and strike the sound block 12 to produce a sound, which will then remind the staff to pay attention to the start of the test. Conversely, when the cylinder 5 pushes the detection head 6 to pull out and reset, the row of toothed blocks 15 simultaneously drives the transmission gear 9 to rotate in reverse, which can also simultaneously reciprocate and strike the sound block 12 to produce a sound, reminding the staff to pay attention to the test results, thus improving the testing efficiency of the riveting test fixture.
