Description

Technical Field

[0001] The utility model relates to the technical field of automobile rear longitudinal beam processing, in particular to a machine tool for processing automobile rear longitudinal beams. Background Technique

[0002] The automobile rear longitudinal beam is one of the important components in the automobile frame structure. It usually extends longitudinally along the automobile body and is located at the rear of the vehicle. The automobile rear longitudinal beam mainly plays the roles of bearing, supporting and transmitting loads, can enhance the strength and stiffness of the body structure, withstand impacts, vibrations and various torsional forces from the road surface during vehicle driving, and can also absorb part of the energy during collisions to ensure the safety of the vehicle occupants.

[0003] During the processing of the automobile rear longitudinal beam, a machine tool will be used to drill holes in the automobile rear longitudinal beam.

[0004] Existing technologies such as the utility model with the publication number of CN217096866U. The utility model relates to the technical field of numerical control machine tools, and discloses a special four-axis processing machine tool for automobile rear longitudinal beams, including a processing table and a supporting mechanism fixedly installed at the bottom of the processing table. A driving device capable of driving the processing is arranged on the top of the processing table. In the utility model, the iron chips falling inside the chip removal groove will be contacted and adsorbed by multiple magnetic columns when floating down, and when the magnetic columns rotate, the bottom of the scraper will simultaneously scrape the iron chips adsorbed on the outer wall of the magnetic columns to one side position. When the pressing plate rotates, it will squeeze and push one side of the scraper. At this time, the magnetic columns will adsorb many iron chip impurities when rotating. When the pressing plate is separated from the scraper, the scraper will scrape the outer wall of the magnetic columns again through the resilience of the spring to scrape the adsorbed materials to one side, so as to continuously collect waste chips, avoid the floating and accumulation of waste chips, thereby achieving the effect of avoiding excessive cleaning by later staff, saving time and effort, and reducing the labor force of the staff, and solving the problem that when the existing processing machine tool grinds and other processes the processed parts, the processed parts will generate a lot of iron chips and other impurities that fly and fall everywhere, resulting in a large amount of waste chips accumulating after the later processing is completed, and it is time-consuming and laborious to clean.

[0005] In daily work, it is found that when the existing machine tool for processing automobile rear longitudinal beams is in use, it is necessary to manually place the rear longitudinal beam on the machine tool and manually clamp the rear longitudinal beam with multiple groups of clamps, resulting in inconvenient operation, not being convenient for quickly aligning the drilling position, and prone to drilling errors, resulting in poor processing quality, and further leading to the problem that the existing machine tool for processing automobile rear longitudinal beams is not convenient for clamping and quickly aligning the drilling position.

[0023] Specifically, the auxiliary device 4 includes brackets 42. There are two brackets 42, and the two brackets 42 are fixedly connected to the surface of the machine tool body 1. A cylinder 41 is fixedly connected to the upper surface of the bracket 42. The output end of the cylinder 41 is fixedly connected to a pressing plate 45. A sliding rod 46 is slidably connected to the inner wall of the pressing plate 45. The lower ends of the two sliding rods 46 are fixedly connected to a positioning member 44. Positioning holes are formed on the surfaces of the pressing plate 45 and the positioning member 44. A groove 48 is formed on one side of the pressing plate 45 close to the positioning member 44. A stabilizing assembly 43 is arranged on the surface of the pressing plate 45.

[0024] In this embodiment: When drilling holes in the rear longitudinal beam of an automobile, the rear longitudinal beam can be placed on the machine tool. Subsequently, after aligning the marked drilling position with the positioning hole on the surface of the positioning member 44, the cylinder 41 is opened. The cylinder 41 drives the pressing plate 45 to press down. After the pressing plate 45 presses to a certain position, the positioning member 44 moves into the groove 48 on the surface of the pressing plate 45 and presses down together with the pressing plate 45 for positioning, so as to facilitate quickly aligning the drilling position and quickly clamping the rear longitudinal beam, improving usability.

[0025] Specifically, the diameters of the positioning holes on the surfaces of the pressing plate 45 and the positioning member 44 are larger than the diameter of the drilling head 3, and the positioning holes are concentric with the drilling head 3.

[0026] Specifically, a spring 47 is sleeved on the surface of the sliding rod 46, and both ends of the spring 47 are fixedly connected to the surfaces of the pressing plate 45 and the sliding rod 46 respectively.

[0027] In this embodiment: The spring 47 can apply pressure to the positioning member 44, thus playing a role in preliminary positioning. At the same time, after the cylinder 41 drives the pressing plate 45 to reset, the spring 47 can drive the positioning member 44 to reset.

[0028] Specifically, a first protective pad 49 is fixedly connected to the lower surface of the pressing plate 45, and a second protective pad 410 is fixedly connected to the lower surface of the positioning member 44.

Subsequently, when drilling holes while clamping the rear longitudinal beam, the rear longitudinal beam is placed on the machine body 1. Then, the spring 47 and the positioning member 44 can press on the rear longitudinal beam. Through the positioning holes on the positioning member 44, the position to be drilled and marked on the rear longitudinal beam can be quickly aligned with the positioning holes. After alignment, the spring 47 and the positioning member 44 can achieve preliminary limiting. The air cylinder 41 is opened, and the air cylinder 41 drives the pressing plate 45 to move.
