[0026] like Figures 1 to 6As shown, a thrust detection mechanism provided by the present invention includes a thrust detection assembly 10 for thrust detection, wherein the thrust detection assembly 10 includes a fixed plate 11, a driving mechanism 12, a push plate 13 and a push head assembly 14, wherein the push plate 13 is slidably mounted on the fixed plate 11, and a plurality of push head assemblies 14 are mounted on the push plate 13, and the driving mechanism 12 is mounted on the fixed plate 11 and is used to drive the push plate 13 to move with the push head assembly 14 on the fixed plate 11. Among them, the driving mechanism 12 can adopt a telescopic cylinder to drive the push plate 13 to slide on the fixed plate 11 by air pressure. Of course, the driving mechanism 12 can also adopt a servo motor with a screw structure to convert the rotation of the servo motor into linear motion.

[0027] By arranging a driving mechanism 12 and a push plate 13 on the fixed plate 11, and arranging a plurality of push head assemblies 14 on the push plate 13, the driving mechanism 12 drives the push plate 13 to move with the push head assemblies 14 on the fixed plate 11, so that the push head assemblies 14 can apply a certain thrust to the spring pieces on the product to detect whether the spring pieces on the product are stable, whether the strength meets the standard, and whether there are abnormalities such as cold welding, thereby realizing automatic detection, thereby replacing manual detection, improving detection efficiency and reducing detection errors.

[0028] like Figure 4 As shown, the push head assembly 14 includes a mounting seat 141, a push head 142, an elastic member 143 and an adjustable tailstock 144. The mounting seat 141 is mounted on the push plate 13, and the push head 142 is slidably mounted on the mounting seat 141. The sliding direction of the push head 142 on the mounting seat 141 is the same as the sliding direction of the push plate 13 on the fixed plate 11. One end of the elastic member 143 abuts against the push head 142, and the other end of the elastic member 143 abuts against the adjustable tailstock 144. The adjustable tailstock 144 is mounted on the mounting seat 141 and is used to adjust the elastic force of the elastic member 143. The elastic force of the elastic member 143 is adjusted by adjusting the tailstock 144, so that the thrust of the push head 142 can be adjusted. Among them, the sliding direction of the push head 142 on the mounting seat 141 and the sliding direction of the push plate 13 on the fixed plate 11 are both left and right directions (reference Figure 1 ). The mounting seat 141 is detachably mounted on the push plate 13 to facilitate the installation and removal between the push head assembly 14 and the push plate 13, and to facilitate the replacement of the push head assembly 14. The elastic member 143 can be a spring. In the initial state, the spring is in a compressed state, so that the distance between the push head 142 and the adjustment tailstock 144 is maximized; when the spring piece on the test product is tested, the spring piece interacts with the push head 142, so that the spring is gradually compressed. Of course, in other embodiments, the elastic member 143 and the adjustment tailstock 144 may not be provided, and the thrust of the push head 142 can be adjusted by adjusting the air pressure of the drive mechanism 12.

[0029] Further, such as Figure 5 and Figure 6As shown, the fixed plate 11 is provided with a slide rail 111, the push plate 13 is provided with a slider 131 matched with the slide rail 111, the slider 131 is provided with a slide groove matched with the slide rail 111, and the push plate 13 slides on the slide rail 111 through the slider 131. The extending direction of the slide rail 111 is the same as the sliding direction of the push head 142 on the mounting seat 141, and both are left and right directions (refer to Figure 1 Each push plate 13 is provided with two slide blocks 131 , and the fixed plate 11 has two slide rails 111 corresponding to each push plate 13 , thereby increasing the stability of the push plate 13 sliding on the fixed plate 11 .

[0030] Furthermore, the fixed plate 11 is provided with a first limit assembly 112 and a second limit assembly 132. After the product inspection is completed, the driving mechanism 12 will drive the push plate 13 to retract and return to its original position. The first limit assembly 112 cooperates with the push plate 13 and is used to limit the position of the push plate 13 when it is retracted, so as to avoid the push plate 13 retracting too far and increasing the inspection time. When inspecting the product, the driving mechanism 12 will drive the push plate 13 to be pushed out and the push head 142 to interact with the product. The second limit assembly 132 cooperates with the fixed plate 11 and is used to limit the position of the push plate 13 when it is pushed out, so as to avoid the push plate 13 being pushed out too far and damaging the qualified product. Among them, the first limit assembly 112 and the second limit assembly 132 both include a connecting seat, a limit rod and a spring. The limit rod is connected to the connecting seat and can slide on the connecting seat. The two ends of the spring are respectively connected to the limit rod and the connecting seat. The spring has an elastic force that moves the limit rod toward the push head assembly 14.

[0031] In this embodiment, the number of the driving mechanism 12 and the push plate 13 are both two, and they are symmetrically installed on the opposite sides of the fixed plate 11, and each push plate 13 is provided with a plurality of push head assemblies 14. Among them, the two driving mechanisms 12 are installed on the opposite sides of the fixed plate 11 in a left-right symmetrical manner, and the two push plates 13 are installed on the opposite sides of the fixed plate 11 in a left-right symmetrical manner. The two driving mechanisms 12 each drive the two push plates 13 to move in opposite directions at the same time. Optionally, each push plate 13 is provided with 12 push head assemblies 14, so that the shrapnel on 12 products can be detected at the same time, and each product has two shrapnel. When the product is detected, the product is located between the push head assemblies 14 on the two push plates 13, so that the two shrapnel on the product can be applied with thrust from the opposite sides of the product. Optionally, a limit baffle 114 is provided on the fixed plate 11, and the limit baffle 114 cooperates with the plurality of push head assemblies 14 on one of the push plates 13, so as to further limit the position of the push plate 13 when it is retracted.

[0032] In this embodiment, Figure 1The thrust detection mechanism also includes a fixed frame 20 and a lifting driver 30, the fixed plate 11 is connected to the lifting driver 30, and the lifting driver 30 is installed on the fixed frame 20 and is used to drive the thrust detection component 10 to move up and down. Among them, the lifting driver 30 can adopt a telescopic cylinder, and the entire thrust detection component 10 slides in the up and down direction on the fixed frame 20 through air pressure. Of course, the lifting driver 30 can also adopt a servo motor with a screw structure to convert the rotation of the servo motor into a linear motion. During the detection, the product will be installed below the thrust detection component 10, and the thrust detection component 10 will be driven to descend by the lifting driver 30 first, and then the push plate 13 will be driven by the driving mechanism 12 to move with the push head component 14 on the fixed plate 11, so that the push head 142 applies a certain thrust to the shrapnel on the product.

Figure 8 It is a schematic diagram of the three-dimensional structure of the thrust detection device in the present invention when the thrust detection component is separated from the verification base. Fig. 9 Schematic diagram of the split structure of the calibration base in the present invention. Figures 7 to 9 As shown, the present application also provides a thrust detection device with a verification function, including a verification base 40 and the thrust detection mechanism as described above, wherein the verification base 40 is used to verify the thrust of the thrust head assembly 14 of the thrust detection mechanism.

[0034] Furthermore, the verification base 40 includes a fixed base 41 and a plurality of pressure sensors 42. The pressure sensors 42 are installed on the fixed base 41 and are used to test the thrust of the push head assembly 14. The working principle of the pressure sensor 42 is to indirectly calculate the thrust by measuring the pressure generated by the push head 142 acting on a certain area, and convert the pressure signal into a usable output electrical signal according to a certain rule. The number of pressure sensors 42 is the same as the number of push head assemblies 14. Each push head assembly 14 corresponds to a pressure sensor 42. The push plate 13 is driven by the driving mechanism 12 to move with the push head assembly 14 on the fixed plate 11, so that the push head 142 on the push head assembly 14 applies thrust to the pressure sensor 42. The pressure sensor 42 can monitor the thrust applied by the push head 142 in real time to test whether the thrust applied by the push head 142 is suitable. If it is not suitable, it can be adjusted by adjusting the tailstock 144. Optionally, a mounting plate 411 is provided on the fixing seat 41 , a plurality of mounting holes 402 are provided on the mounting plate 411 , and the pressure sensor 42 is installed in the mounting hole 402 and exposed from the opening of the mounting hole 402 .

[0035] Furthermore, a coordination guide column 113 is provided on the fixed plate 11 of the thrust detection mechanism, and a coordination guide hole 401 corresponding to the coordination guide column 113 is provided on the verification base 40. The thrust detection assembly 10 and the verification base 40 are positioned and paired through the coordination guide column 113 and the coordination guide hole 401, thereby ensuring that the push head 142 is aligned one by one with the pressure sensor 42.

[0036] Furthermore, the thrust detection device includes a machine platform, the thrust detection component 10 is installed on the machine platform through a fixing frame 20 , and the product installation fixture and the verification base 40 can be detachably installed on the machine platform and are located below the thrust detection component 10 .

[0037] The working process of thrust detection equipment includes: When it is necessary to test the thrust of the push head assembly 14 of the thrust detection mechanism, the product installation fixture is removed from the machine platform, and the verification base 40 is installed on the machine platform and located below the thrust detection assembly 10; the thrust detection assembly 10 is first driven down by the lifting driver 30, and the thrust detection assembly 10 and the verification base 40 are accurately positioned by the matching guide column 113 and the matching guide hole 401; then the push plate 13 is driven by the driving mechanism 12 to move the push head assembly 14 on the fixed plate 11, so that the push head 142 on the push head assembly 14 applies thrust to the pressure sensor 42, and the pressure sensor 42 can monitor the thrust applied by the push head 142 in real time to check whether the thrust applied by the push head 142 is appropriate; if the thrust is not appropriate, it can be adjusted by adjusting the tailstock 144, and then the inspection is carried out until it is qualified.

[0038] When testing the product, the verification base 40 is removed from the machine, and the product installation fixture is installed on the machine and located below the thrust detection component 10; first, the thrust detection component 10 is driven down by the lifting drive 30, and the thrust detection component 10 and the product installation fixture are accurately positioned through the matching guide column 113 and the guide hole on the product installation fixture; then the push plate 13 is driven by the driving mechanism 12 to move with the push head assembly 14 on the fixed plate 11, so that the push head 142 applies a certain thrust to the spring piece on the product, thereby detecting the spring piece on the product.

[0039] Among them, the verification base 40 is only a verification action on the push head assembly 14 when the machine is turned on for inspection, when cold soldering occurs during the production process, or when the number of inspections reaches a certain number. In normal production, when each group of products arrives at the thrust detection station, the push head assembly 14 must perform real-time inspection on the products.
