[0031] In order to enable those skilled in the art to better understand the technical solutions in this application, the following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0032] Please refer to Figure 1-Figure 5 A guide rail and slider service life test tool includes a base 100 and a driving mechanism 200 arranged at a central position on the upper end of the base 100, an adjustment component 300, a guide rail body 400, a sliding component 500, a slider body 600 and a test component 700.

[0033] The adjustment assembly 300 is symmetrically arranged on the left and right sides of the upper end surface of the base 100 . A guide rail body 400 is arranged at the upper end of the adjustment assembly 300 , and the adjustment assembly 300 is used to adjust the position of the guide rail body 400 and to disassemble it.

[0034] The driving mechanism 200 includes a stepper motor 210, a connecting screw rod 220 and a support seat 230. The stepper motor 210 is fixed to one side of the upper end surface of the base 100, the connecting screw rod 220 is fixed to the output end of the stepper motor 210, and the support seat 230 is connected to the other end of the connecting screw rod 220 and connected to the base 100.

[0035] The sliding assembly 500 is threadedly connected to the outer surface of the connecting screw rod 220 and can be slidably adjusted left and right. The upper end of the sliding assembly 500 is clamped with a slider body 600, and the slider body 600 can be slidably clamped on the inner side of the guide rail body 400.

[0036] The testing component 700 is disposed on the upper ends of the supporting base 230 and the sliding component 500 , and is used to detect the sliding times of the sliding component 500 .

[0037] Please refer to Figure 1-Figure 3The adjustment assembly 300 includes a connection seat 310, a connection slide 320, an adjustment screw rod 330 and an adjustment handle 350. The connection seat 310 is slidably connected to the left and right sides of the upper end surface of the base 100. The connection slide 320 is evenly fixed to the lower end surface of the connection seat 310 and is provided with three groups. The cross section of the connection slide 320 is a "T"-shaped structure. The adjustment screw rod 330 is located inside the base 100 and is threadedly connected to the central position inside the connection slide 320. The adjustment handle 350 is fixed to one end of the adjustment screw rod 330. The adjustment handle 350 can drive the adjustment screw rod 330 to rotate, and when the adjustment screw rod 330 rotates, the connection slide 320 can slide along the upper end of the base 100, so that the position of the connection seat 310 can be adjusted as needed.

[0038] The connecting slide bar 340 is slidably connected in the left and right groups of connecting slides 320. The connecting slide bar 340 is arranged to pass through the inner side of the two groups of connecting slides 320 horizontally, thereby limiting the position of the connecting slide 320, ensuring that the connecting slide 320 is more stable when sliding left and right, so that the application range of the device is further improved.

[0039] The connection seat 310 includes a connection slot 311 and a locking bolt 312. The connection slot 311 has a trapezoidal cross section and is provided on the upper end surface of the connection seat 310. The guide rail body 400 is slidably engaged with the inner side of the connection slot 311. The locking bolt 312 is evenly arranged on one side of the connection seat 310 and passes through the connection seat 310 to connect with the guide rail body 400. The guide rail body 400 can be slidably engaged with the inner side of the connection slot 311, thereby preventing the guide rail body 400 from being offset. Then, the locking bolt 312 passes through the connection seat 310 to connect with the guide rail body 400, so that the position of the guide rail body 400 can be quickly limited.

[0040] When in use, the guide rail body 400 can be slidably engaged in the connecting slot 311 on the inner side of the connecting seat 310, and the position of the guide rail body 400 can be limited by multiple sets of locking bolts 312. Then, by rotating the adjustment handle 350, the adjustment screw rod 330 connected to one end of the adjustment handle 350 can cooperate with the connecting slide 320 to adjust the position of the connecting seat 310, so that it can be adjusted according to the different sizes of the guide rail body 400.

[0041] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5The sliding assembly 500 includes a sliding seat 510, a driving shaft 520, a driving gear 540, a locking plate 550, a limiting slide groove 560 and a stepped clamp 570. The sliding seat 510 is threadedly connected to the outer surface of the connecting screw 220, the driving shaft 520 is laterally fixed at the central position of the sliding seat 510, the driving gear 540 is fixed at the central position of the driving shaft 520, the locking plate 550 is symmetrically meshed and connected to the upper and lower ends of the driving gear 540, the limiting slide groove 560 is opened on the outer side of the locking plate 550 and the cross-section of the limiting slide groove 560 is a "T"-shaped structure, and is clamped with the protrusion on the inner wall of the sliding seat 510, the stepped clamp 570 is fixed on the outer side of the locking plate 550, the slider body 600 is slidably clamped in the interior of the sliding seat 510, and is clamped with the slider body 600 through the stepped clamp 570 at one end of the locking plate 550. The sliding seat 510 can slide along the outer surface of the connecting screw 220, so that the slider body 600 can be easily slid along the guide rail body 400, so that the subsequent detection can be convenient. Then, the driving shaft 520 can drive the driving gear 540 to rotate, so that the position of the locking plate 550 can be adjusted, so that the step clamp 570 is engaged with the slider body 600, so as to facilitate the subsequent position of the slider body 600. At the same time, the limited slide groove 560 can be used to limit the position of the locking plate 550, so as to avoid the locking plate 550 from being offset, so as to ensure the stability of the subsequent adjustment of the locking plate 550. The left and right ends of the outer surface of the driving shaft 520 are provided with a torsion spring 530. The torsion spring 530 can reset the driving shaft 520, so that the driving shaft 520 is always in a counterclockwise rotation state, and the driving gear 540 can cooperate with the locking plate 550 to engage and limit the slider body 600.

[0042] If it is necessary to limit the position of the slider body 600, the drive shaft 520 can be rotated clockwise to adjust the position of the locking plate 550 through the drive gear 540, and then the two groups of slider bodies 600 are slidably connected to the left and right sides of the sliding seat 510. Then, the drive shaft 520 is loosened, and the torsion spring 530 is set to reset the drive shaft 520, and then the stepped clamp 570 at one end of the locking plate 550 can be connected to the slider body 600, so that the position of the slider body 600 can be quickly limited to avoid the slider body 600 from being offset.

[0043] The test assembly 700 includes a push counter 710 and a push contact end 720 . The push counter 710 is arranged on the upper end surface of the support seat 230 . The push contact end 720 is fixed on the upper end surface of the sliding seat 510 , and the upper end of the push contact end 720 contacts the lower end of the push counter 710 . The push-type counter 710 is set to count when pressed, and when the stepper motor 210 drives the connecting screw 220 to rotate, the slider body 600 on the outside of the sliding seat 510 can slide in the guide rail body 400, so that it is pushed toward the side close to the push-type counter 710, and when the sliding seat 510 slides to the specified position, the pressing contact end 720 at the upper end of the sliding seat 510 can contact the push-type counter 710, and then, the stepper motor 210 stops and rotates in the opposite direction, so that the sliding seat 510 can reciprocate along the outside of the connecting screw 220. When the sliding seat 510 reciprocates once, the set pressing contact end 720 can reciprocate and press the push-type counter 710 once, and the push-type counter 710 can count for subsequent reference. At the same time, this test tool can test two groups of guide rail bodies 400 and slider bodies 600 at the same time, so that data information comparison can be realized, the test error can be minimized, and the accuracy of the test can be ensured.

[0044] In some examples, the push-type counter 710 is a prior art, and the push-type counter 710 can count when it is pressed, so it is not described in detail in this application document.
