[0022] Example

[0023] When performing strength testing on hardware stainless steel pipe fittings, the stainless steel pipe needs to be placed on a fixture structure provided on the testing device, and the fixture structure needs to be manually operated to clamp and fix the stainless steel pipe. However, when performing a pressure test on the strength of the stainless steel pipe through a pressure testing structure, the pressure testing structure and the fixture structure cannot be linked, resulting in low efficiency in quality testing.

[0025] It also includes a linkage type holding structure 5 , which is installed on the testing platform 1 and connected to the rear side wall of the lifting seat 31 .

[0026] The pressure sensor 34 can detect the applied pressure and display it through the pressure monitor 4 to facilitate manual identification of the applied pressure value.

[0027] Further as Figure 1-3 As shown, it is worth noting that a pressure monitor 4 is fixedly connected to the right edge of the front side wall of the testing platform 1 , and the pressure monitor 4 is electrically connected to the pressure sensor 34 .

[0028] Further as Figure 1-3As shown, it is worth mentioning that the linkage holding structure 5 includes two symmetrically arranged bottom brackets 52 slidingly connected to the top of the detection platform 1, the bottom ends of the bottom brackets 52 are fixedly connected to sliding seats 51 with a convex vertical cross-section, and the sliding seats 51 are slidably connected to the sliding grooves provided at the top of the detection platform 1, and the tops of the bottom brackets 52 are provided with V-shaped brackets. A transmission structure is connected between the two sliding seats 51 and the detection platform 1 and the lifting seat 31, and the tops of the two bottom brackets 52 are provided with top pressure seats 54. The top pressure seats 54 are slidably sleeved on the outside of two symmetrically arranged guide rods 53, and the bottom ends of the guide rods 53 are fixed to the tops of the bottom brackets 52. The bottoms of the top pressure seats 54 are provided with inverted V-shaped pressure grooves, and the front and rear ends of the two top pressure seats 54 are fixedly connected to transmission columns 56 through inverted L-shaped connecting rods 55. V-shaped transmission channels 57 are opened on the front and rear side walls of the detection platform 1, and one end of the transmission column 56 is movably overlapped in the V-shaped transmission channel 57.

[0029] The width of the V-shaped transmission channel 57 is equal to the diameter of the transmission column 56, which can prevent the transmission column 56 from moving inside the channel.

[0030] Further as Figure 1-3 As shown, it is worth mentioning that the transmission structure includes the same bidirectional screw 58 threadedly connected on the two sliding seats 51, both ends of the bidirectional screw 58 are rotatably connected to the sliding groove, the middle part of the bidirectional screw 58 is rotatably connected to the detection platform 1, and the middle part of the bidirectional screw 58 is fixed with a worm gear 59, which is located in a groove provided at the top of the detection platform 1, and the lower part of the worm gear 59 is meshedly connected with a worm 510, which is rotatably connected to the detection platform 1 through a transmission shaft 511. The rear end of the transmission shaft 511 extends to the rear side of the detection platform 1 and is fixed with a gear 512, and the outer side of the gear 512 is meshedly connected with a plurality of teeth 513, and the plurality of teeth 513 are arranged in an equidistant array and are fixed to the inner wall of the n-shaped channel provided on the inverted L-shaped transmission rod 514, and the top of the inverted L-shaped transmission rod 514 is fixed to the rear side wall of the lifting seat 31.

[0031] After the multiple teeth 513 move the inverted L-shaped transmission rod 514 downward, they will transmit the gear 512, causing the gear 512 to rotate, but the multiple teeth 513 will not continue to transmit the gear 512, so that the worm 510 can self-lock the worm wheel 59.

[0032] In summary: When using the hardware machining quality inspection device, first place the hardware stainless steel pipe fittings to be inspected on the two bottom brackets 52, and by starting the hydraulic cylinder 3, push the lifting seat 31 downward, thereby driving the inverted L-shaped transmission rod 514 together with the multiple teeth 513 to move downward, and prompting the multiple teeth 513 to transmit the gear 512, prompting the transmission shaft 511 to drive the worm 510 to rotate, and the worm 510 to transmit the worm wheel 59, and the worm wheel 59 will drive the bidirectional screw 58 to rotate, so that the bottom brackets 52 connected to the two sliding seats 51 can move relative to each other, however, with the inverted L-shaped connection The action of the transmission column 56 connected to the rod 55 in the transmission channel 57 causes the two bottom supports 52 to move relative to each other, and the two top pressure seats 54 to move downward at the same time, and to achieve fixed pressure on both ends of the hardware stainless steel pipe fittings. However, with the self-locking effect of the worm gear 59 and worm 510, the pressure holding remains effective, but the pressure plate 33 will continue to move downward and cause the pressure plate 33 to apply pressure to the hardware stainless steel pipe fittings. When the T-shaped movable seat 32 is moved upward to press the pressure sensor 34, the pressure of the hardware stainless steel pipe fittings can be detected until they are damaged, thereby facilitating the detection of the quality of the hardware stainless steel pipe fittings and greatly improving the efficiency of detection.
