The liquid storage assembly 52 includes a liquid storage tank 521 fixed to the top side of the support table 51, the inside of the liquid storage tank 521 is provided with a stirring rod 522 extending to the outside thereof, and the top end of the stirring rod 522 is rotatably installed with a connecting plate 523 connected with the abutting assembly 53;

[0047] Specifically, the liquid storage assembly 52 further comprises a guide sleeve 524 fixed to the top side of the liquid storage tank 521, the inside of the guide sleeve 524 is provided with a guide shaft 525, the inside of the guide sleeve 524 is hollow, and the stirring rod 522 penetrates through the inside of the guide sleeve 524. The inside of the stirring rod 522 is provided with a guide groove 526 in a spiral shape, and the end of the guide shaft 525 is in rolling connection with the guide groove 526. The guide groove 526 is arranged in the inside of the stirring rod 522 and has a spiral shape, and the end of the guide shaft 525 is in rolling connection with the guide groove 526. When the stirring rod 522 moves up and down under the action of the abutting assembly 53, the guide shaft 525 rolls in the guide groove 526. Due to the spiral shape of the guide groove 526, the stirring rod 522 generates rotary motion to realize the stirring function, and the motion conversion principle is utilized, so that an additional driving device is not needed to drive the stirring rod 522 to rotate.

[0048] It can be understood that the connecting plate 523 serves to connect the stirring rod 522 and the abutting assembly 53, and transmits the power of the abutting assembly 53 to the stirring rod 522 to realize the driving of the stirring rod 522. The stirring rod 522 can stir the lubricating liquid in the liquid storage tank 521. Since the lubricating liquid may be precipitated, stratified and the like during storage, the stirring action of the stirring rod 522 can uniformly mix various components in the lubricating liquid, ensure the performance stability of the lubricating liquid, thereby improving the lubricating effect and prolonging the service life of the equipment parts.

[0050] Moreover, the reset spring two 547 is mounted between the contact table 543 and the pump cylinder 541, and after the contact table 543 moves downward under the pushing of the connecting plate 523, the elastic force of the reset spring two 547 can reset the contact table 543 and the piston 542 upward, so as to ensure that the piston 542 can continuously reciprocate, thereby realizing the continuous delivery of the lubricating liquid.

[0051] In order to further improve the delivery effect, the liquid storage tank 521 is provided with a marking assembly one 55, which comprises a floating frame 551 slidingly arranged in the liquid storage tank 521, and a marking plate 552 mounted at the top side of the floating frame 551 and extending above the liquid storage tank 521; specifically, the floating frame 551 floats up and down with the liquid level in the liquid storage tank 521, and drives the marking plate 552 to move synchronously above the liquid storage tank 521. The staff or the user can intuitively and quickly know the remaining amount of the liquid in the liquid storage tank 521 by observing the position of the marking plate 552, without complicated measurement or estimation, so as to conveniently and timely grasp the delivery progress and reasonably arrange subsequent operation.

[0052] Meanwhile, the delivery process is facilitated to monitor, and the position change of the marking plate 552 can reflect the consumption of the liquid in real time during the delivery process, so that the staff can judge whether the delivery is normally performed according to the moving speed and position of the marking plate 552, for example, whether the delivery is too fast or too slow, and whether it is close to the end of the delivery, so as to timely take corresponding measures to guarantee the safety and effectiveness of the delivery.

[0056] In combination with the accompanying drawings, Figures 1-8 The working principle of the above embodiment is as follows:

[0057] The angle steel is placed on the material conveying frame 2, and the angle steel is pushed to the appropriate position by the pushing structure 21 to prepare for the subsequent marking operation. The mounting table 31 slides on the linear track one 1 to realize the movement in the X-axis direction. At the same time, the linear track two 32 slides on the inner side of the mounting table 31 to realize the movement in the Y-axis direction. The two driving structures 33 are respectively in transmission cooperation with the guide racks 12 on the inner sides of the linear track one 1 and the linear track two 32 to drive the mounting table 31 and the linear track two 32 to move, so as to move the marking device 4 above the position where the angle steel needs to be marked.

[0058] When the laser marking is performed, the linear module in the marking device 4 starts fine adjustment. The upper linear module is driven by the driving motor 48 through the synchronous part 410 to adjust the horizontal fine position of the laser head, and the lower linear module drives the laser cutting head 46 and the base 47 to move vertically along the Z-axis to adjust the laser focal length, so as to ensure that the clearest marking effect can be obtained on angle steels with different heights or different specifications. Finally, the laser emits laser light, which is focused by the laser cutting head 46 and irradiated to the surface of the angle steel, so as to form permanent marks by ablation or melting of the material surface.

[0059] Furthermore, the lubricating mechanism 5 works automatically during the whole mechanical movement, ensuring the smoothness and durability of the kinematic pairs such as guide rails and screw rods; when the mounting table 31 reciprocates in the X-axis direction, the abutting assembly 53 fixed thereon moves with it. The abutting rod 531 and the abutting block 532 will periodically press down the connecting plate 523 in contact with it; the connecting plate 523 is pressed down to drive the stirring rod 522 to rotate, and the internal guide groove 526 cooperates with the fixed guide shaft 525 to convert linear motion into rotary motion, prevent the additives in the lubricating liquid from precipitating, and the connecting plate 523 is pressed down at the same time to push the abutting table 543, drive the piston 542 to move downward in the pump cylinder 541, pump the lubricating liquid into the delivery pipe 546 through the bottom check valve 544 and the communication pipe 545, and finally deliver it to the guide rail that needs to be lubricated; when the abutting block 532 leaves, the reset spring 1 533 and the reset spring 2 547 reset the piston 542 and the connecting plate 523, completing a cycle of liquid suction and pumping.

[0060] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
