[0034] The utility model discloses a system for testing the durability of a lightweight slide rail for a machine. Figure 1 As shown, it includes a durable base 50, a left durable upright plate 51, a right durable upright plate 52, and a load plate 53.

[0035] The durable base 50 is set horizontally and is installed on the machine tool; the left durable vertical plate 51 is in an inverted "T" shape, the horizontal section of the left durable vertical plate 51 is attached to the durable base 50, and the vertical section of the left durable vertical plate 51 extends upward.

[0036] The right durable upright board 52 is in an inverted "T" shape, with its horizontal section attached to the durable base 50 and its vertical section extending upward; and is arranged at a predetermined distance relative to the left durable upright board 51.

[0037] The load plate 53 is U-shaped and is formed by integrally connecting two third ear plates 54 and a third bottom plate 55. The outer sides of the two third ear plates 54 are respectively fixedly connected to the inner sides of the inner rails 30 of the two portable machine slide rails.

[0038] The inner sides of the vertical sections of the oppositely arranged left durable upright plate 51 and the right durable upright plate 52 are respectively fixedly connected to the outer sides of the outer rails 30 of the two machine-use portable slide rails.

[0039] The upper side of the third bottom plate 55 of the load plate 53 is used to place a standard weight for testing, and the end of the third bottom plate 55 is used to be fixed to the testing machine, thereby repeatedly pulling the inner track and testing the durability of the slide rail.

[0040] like Figure 3 As shown, the machine-use lightweight slide rail includes: an outer rail 10, a middle rail 20, and an inner rail 30. The side of the outer rail 10 is installed on the machine body; the middle rail 20 is sleeved in the outer rail 10 and can slide along the direction of the outer rail 10; the inner rail 30 is sleeved in the middle rail 20 and can slide along the direction of the middle rail 20.

[0041] The present invention further includes a pressing rod, which is located on the upper side of the trigger rod 42 of the portable machine slide rail. The pressing rod is used to press the free end of the trigger rod 42 of the portable machine slide rail downward when the inner rail 30 slides out of the middle rail 20, thereby retracting the inner rail 30 into the middle rail 20, and the middle rail 20 retracts into the outer rail 10.

[0042] This utility model can continuously and stably perform repetitive movements. By adding a monitoring device to the load plate 53, the test process can be monitored and statistically analyzed, achieving the purpose of visual testing. The load plate 53 has a positioning hole at the front end for connection to the detection device. The left and right durable uprights 51 and 52 can be installed with lightweight machine rails of different sizes. The durable base 50 has holes at different intervals to simulate the working conditions of lightweight machine rails of different widths, improving the adaptability of the device, thereby increasing test efficiency and saving test costs.

[0043] The utility model has the advantages of flexible operation, good versatility, light structure and easy processing, and is suitable for durability testing of complete work processes of light machine slide rails of different sizes under different load conditions.

[0044] like Figure 2 As shown, the portable slide rail for machines applicable to the present invention specifically includes: an outer rail 10 , a middle rail 20 , an inner rail 30 , and a fixing bracket 40 .

[0045] The outer rail 10 is installed on the side of the machine body; the middle rail 20 is sleeved inside the outer rail 10 and can slide along the direction of the outer rail 10; the inner rail 30 is sleeved inside the middle rail 20 and can slide along the direction of the middle rail 20; the inner side of the inner rail 30 is used to install the support plate; one end of the inner rail 30 is the inner end, and the other end is the outer end.

[0046] The fixing bracket 40 is fixedly connected to the inner end of the inner rail 30. The fixing bracket 40 is used to clamp the inner rail 30 after the middle rail 20 extends out of the outer rail 10 and the inner rail 30 fully extends out of the middle rail 20, forcing the inner rail 30 to remain in a fully extended state, thereby allowing the support plate installed on the inner rail 30 to extend outward and present the items carried on the support plate.

[0047] The cross section of the outer rail 10 is U-shaped. The outer rail 10 is composed of a first side plate 11 and two first ear plates 12 connected as one body. The inner walls of the two first ear plates 12 are provided with first grooves 13 .

[0048] The cross-section of the middle rail 20 is "U"-shaped. The middle rail 20 is composed of a second side plate 21 and two second ear plates 22 connected as one body. The outer walls of the two second ear plates 22 are provided with a second groove 23; the second groove 23 and the first groove 13 cooperate with each other to form a first accommodating area for accommodating multiple first steel balls, each of which is used to reduce the friction between the outer rail 10 and the middle rail 20.

[0049] A third groove is provided on the inner walls of the two second ear plates 22, and a fourth groove 31 is provided on the inner rail 30 at a position corresponding to the third groove. The third groove and the fourth groove 31 cooperate with each other to form a second accommodating area for accommodating multiple second steel balls, each of which is used to reduce the friction between the inner rail 30 and the middle rail 20.

[0050] A first stopper 14 is fixedly connected to an opening at one end of the outer rail 10, and the first stopper 14 is used to prevent the middle rail 20 from sliding out of the inner cavity of the outer rail 10. A second stopper 25 is fixedly connected to an opening at one end of the middle rail 20, and the second stopper 25 is used to prevent the inner rail 30 from sliding out of the inner cavity of the middle rail 20.

[0051] Both ends of the first accommodating area and the second accommodating area are provided with fixing pins for preventing the first steel ball and the second steel ball from overflowing from the first accommodating area and the second accommodating area.

[0052] The fixing bracket 40 is located in the middle section of the middle track 20. Figure 4 As shown, the fixing bracket 40 includes a limiting plate 41 and a trigger rod 42 .

[0053] like Figure 5As shown, one end of the limit plate 41 is fixedly connected to the inner end of the inner rail 30; the middle part of the trigger rod 42 is hinged to the other end of the limit plate 41; the trigger rod 42 is arranged along the direction of the inner rail 30, and the trigger rod 42 is used to abut against the other end of the outer rail 10, thereby clamping the middle rail 20 and preventing the middle rail 20 and the inner rail 30 from retracting into the inner cavity of the outer rail 10.

[0054] An elastic member accommodating groove is provided on the trigger rod 42. The end of the limit plate 41 extends outward and wraps around the trigger rod 42 and then extends toward the axis of the inner track 30 to form a third accommodating area, which is used to accommodate the trigger rod 42. The two ends of the trigger rod 42 are respectively a free end and a limit end 43.

[0055] The fixing bracket 40 also includes: a first elastic member, one end of the first elastic member extends into the elastic member receiving groove, and the other end of the first elastic member is fixedly connected to the corresponding limiting plate 41. The first elastic member is used to force the limiting end 43 of the trigger rod 42 to approach the middle rail 20 and abut against the end of the outer rail 10 after it is separated from the outer rail 10.

[0056] The free end of the trigger rod 42 is also used to press the inner rail 30 along the axial direction of the inner rail 30, and force the limiting end 43 of the trigger rod 42 to move away from the middle rail 20 and be located outside the outer rail 10, thereby moving with the inner rail 30 when the inner rail 30 and the middle rail 20 are contracted.

[0057] During use, the slide rail of the present invention is installed by installing a support plate between the two inner rails 30, and placing electronic components on the support plate. The rails of the present invention are installed in multiple cavities arranged from top to bottom on a mounting frame. Therefore, each pair of slide rails needs to be installed with a support plate, and different electronic components are placed on them respectively.

[0058] The slide rail of the present invention is provided with two mirror-image outer rails 10, middle rails 20, and inner rails 30. The two outer rails 10, middle rails 20, and inner rails 30 are arranged opposite each other and installed in the same accommodating cavity. The installation position of the first elastic member in the present invention should be biased towards the limiting end of the trigger lever 42. This allows the limiting end to more easily approach the middle rail 20 and abut the end of the outer rail 10. It also facilitates the limiting end of the trigger lever 42 to abut against the outer rail 10 after the free end of the trigger lever 42 loses force.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
