Utility Model Content

[0005] The purpose of this utility model is to provide a moving crossbeam for a material testing machine, which solves the problem that although the moving crossbeam of the existing material testing machine adopts the cooperation of a drive motor, screw and other structures to complete the movement of the crossbeam, the movement of the crossbeam becomes stuck due to the friction between materials after a long period of use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a moving crossbeam for a material testing machine, comprising a control console, four evenly distributed support feet fixedly connected to the lower end of the control console, a support beam fixedly connected to the upper end of the control console, a groove formed on the inner side wall of the support beam, a slider slidably connected to the inner wall of the groove, a crossbeam body fixedly connected to the end face of the slider, a synchronous motor fixedly mounted on the horizontal part of the support beam, the output shaft of the synchronous motor rotatably connected to the support beam, a screw fixedly connected to the output shaft of the synchronous motor, the screw and the slider being threadedly connected, a lubrication mechanism shared by the slider and the support beam, and a positioning mechanism shared by the screw and the control console.

In addition, the oil suction sleeve can lubricate the screw and slider to avoid the problem of the crossbeam body moving and getting stuck.

[0015] 2.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The lubrication mechanism 8 includes a clearance groove 80. The surface of the support beam 2 has a clearance groove 80, which is connected to the slide groove 3. An oil suction sleeve 81 is fixedly connected to the upper end of the slider 4. The oil suction sleeve 81 is slidably connected to the screw 7. A support tube 82 is fixedly connected to the side of the oil suction sleeve 81. An oil storage box 84 is fixedly sleeved on the outside of the support tube 82. An end plate 85 is in contact with the end face of the oil storage box 84 away from the support beam 2. A traction line 86 is fixedly connected to the end face of the end plate 85. The traction line 86 is slidably connected to the oil storage box 84. A sealing device is fixedly connected to the end of the traction line 86. The inner wall of the sealing disc 87 and the oil storage box 84 is fixedly connected to a guide roller 88, which is in contact with the traction line 86. The inner wall of the oil storage box 84 is also fixedly connected to a guide roller 89, which is in contact with the traction line 86. An elastic element 890 is bonded to the side of the guide roller 89, and the other end of the elastic element 890 is bonded to the sealing disc 87. By pulling the end plate 85, the traction line 86 can be moved, thereby causing the sealing disc 87 to detach from the support tube 82, allowing the lubricating oil to circulate and ultimately lubricate the screw 7 and the slider 4.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4A movable disc 83 is fixedly sleeved on the outside of the support pipe 82. The movable disc 83 is slidably connected to the support beam 2. The movable disc 83 can be used to guide the movement of the support pipe 82. The sealing disc 87 is slidably connected to the oil storage box 84. The sealing disc 87 is in contact with the support pipe 82. The sealing disc 87 can be used to seal the support pipe 82. An elastic element 891 is bonded to the end face of the sealing disc 87. The other end of the elastic element 891 is bonded to the oil storage box 84. The sealing disc 87 can be connected by the elastic element 891.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 The positioning mechanism 9 includes a rotating disk 90. ​​The lower end of the screw 7 is fixedly connected to the rotating disk 90, which is rotatably connected to the control console 1. The surface of the rotating disk 90 is provided with multiple insertion holes 91, which are arranged in a circular array on the rotating disk 90. ​​The insertion holes 91 facilitate the insertion of the insertion rod 93. The upper end of the control console 1 is fixedly connected to a fixing plate 92, and the inner wall of the fixing plate 92 is slidably connected to the insertion rod 93. The insertion rod 93 is slidably connected to the insertion hole 91. The end face of the insertion rod 93 is fixedly connected to an iron disk 94, and an elastic rope 95 is glued to the end face of the iron disk 94. The other end of the elastic rope 95 is glued to the fixing plate 92. An electromagnet 96 is fixedly installed on the upper end of the control console 1. Through the cooperation of the electromagnet 96 and the iron disk 94, the movement of the insertion rod 93 can be controlled, thereby keeping the rotating disk 90 in an unrestrained state to ensure the normal rotation of the screw 7.

[0027] The specific implementation process of this utility model is as follows: In use, the electromagnet 96 is activated to magnetically attract the iron disc 94, thereby pulling the insertion rod 93 to slide along the inner wall of the fixed plate 92, causing the elastic rope 95 to deform. When the iron disc 94 contacts the electromagnet 96, the insertion rod 93 disengages from the insertion hole 91. The output shaft is driven to rotate by the synchronous motor 6, thereby driving the screw 7 to rotate. Under the threaded connection, the slider 4 can be driven to slide along the inner wall of the slide groove 3, and the crossbeam body 5 can be moved to dynamically adjust the position of the crossbeam body 5. When the synchronous motor 6 is turned off, the electromagnet 96 is also turned off, causing the electromagnet 96 to lose its magnetic attraction, and the elastic rope 95 to recover its deformation, thereby pulling the iron disc 94 to move, so that the insertion rod 93 inserts into the next insertion hole 91 on the surface of the rotating disc 90, limiting the rotation of the rotating disc 90, preventing excessive deflection of the screw 7, stabilizing the position of the crossbeam body 5, and using it for precise control.

[0028] When the slider 4 moves, it can drive the oil suction sleeve 81 to slide along the surface of the screw 7, and drive the support tube 82 to move, which in turn drives the oil storage box 84 to move. This can pull the end plate 85 to move away from the oil storage box 84, thereby pulling the traction line 86 to move. The traction line 86 moves along the surfaces of the first guide roller 88 and the second guide roller 89 to ensure the stability of the movement of the traction line 86, and drives the sealing plate 87 to move, causing the first elastic element 890 and the second elastic element 891 to deform. Finally, the sealing plate 87 is separated from the support tube 82. Under the action of the support tube 82 and the oil suction sleeve 81, the lubricating oil can circulate and be absorbed, and finally the lubricating oil comes into contact with the screw 7 and the slider 4 to ensure a good driving effect.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
