[0002] In the automotive manufacturing industry, the processing and assembly of tube beams are widely used. These tube beam processing procedures are numerous. For example, the processing of a bumper beam includes processes such as stretch bending, punching, drilling, and riveting. There will be a large number of hole features and irregular notch features on the bumper beam. These features are mainly installation holes reserved for riveting and clearance notches for vehicle assembly. In the processing of the above holes and notches, punching and drilling processes are mainly used. When processing the bumper beam, due to the processing characteristics of each process, they are processed step by step independently and produced in a single process. In this way, at least two devices will be planned, and it may also be more devices. When multiple sequential processing devices are put into use, the number of operators will also increase, and the turnover logistics, etc. will all increase. This greatly increases the processing cost of the product. In addition, for the tube beam processed in multiple processes, involving multiple loading and positioning operations, it is bound to bring the accumulation of loading, positioning, and processing errors, and the position and processing accuracy of the hole positions and notch features will inevitably decrease, which will also indirectly affect the strength of the workpiece and the vehicle body.

[0014] Figure 2 is the partial structural schematic diagram of the present utility model.

[0017] The following combines the drawings and embodiments to further elaborate on the present utility model in detail.
[0018] As Figure 1-2 shown, the present utility model includes a frame 1, on which a cross beam 1-1 is provided, and a drilling assembly 2 is provided on the cross beam 1-1. The drilling assembly 2 is arranged according to the processing hole positions and the number of holes of the pipe beam to be processed.
[0019] The bottom of the frame 1 is connected to the workbench 1-2, and this connection can be a movable connection or a fixed connection. The movable connection can adjust the position of the frame 1 relative to the workbench 1-2; a fixture 3 is provided on the workbench 1-2, and the number and arrangement position of the fixture 3 depend on the shape of the pipe beam to be processed and the hole positions to be processed; for the pipe beam to be processed being an automobile anti-collision beam with a symmetrical curvature, the required fixture 3 can be 4-6 groups, which cooperate with each other to complete the fixation of the anti-collision beam.
[0020] A punching assembly 4 is also provided on the workbench 1-2, and the punching assembly 4 is movably connected to the workbench 1-2.
[0021] The number of the drilling assemblies 2 can be 2-3 groups, or can be set according to needs; each group of drilling assemblies 3 is composed of a power head, a transmission mechanism and 3-4 drill bits. The positional relationship between the drill bits depends on the shape of the pipe beam to be processed and the hole positions to be processed. The transmission mechanism is a multi-spindle head, and the multi-spindle head distributes the power of the power head to multiple drill bits.
[0022] To facilitate the adjustment of the position of the drilling assembly relative to the workbench 1-2: a first adjustment assembly is further provided between the drilling assembly 2 and the cross beam 1-1; the first adjustment assembly is composed of a first slide rail 1-1-1 provided on the cross beam 1-1 and a first slider provided on the drilling assembly 2. The first slide rail 1-1-1 is horizontally arranged and matches the first slider. The drilling assembly 2 can slide along the first slide rail 1-1-1 to adjust the position.
[0023] The locking of the drilling assembly 2 during sliding relies on the locking screw provided on the first slider. By screwing the locking screw, the head of the screw presses against the horizontal slide 1-1-1, thereby realizing locking and stopping. The locking of the sliding pair is a conventional technology and will not be elaborated further.
[0024] For facilitating the adjustment of the position of the punching component 4 relative to the workbench 1-2: A second adjustment component is further provided between the punching component 4 and the workbench 1-2; the second adjustment component consists of an intermediate seat 5 and a second slide rail 1-2-1 provided on the workbench 1-2. The second slide rail 1-2-1 is horizontally arranged, and a second slider matching the second slide rail 1-2-1 is provided on the intermediate seat 5. The intermediate seat 5 can slide horizontally along the second slide rail 1-2-1.
[0025] Since the outer shape of the pipe beam to be processed may have a curvature, such as an anti-collision beam, and the curvature position is not fixed, in order to make the punching component 4 perpendicular to the surface to be processed of the pipe beam to be processed, the following solution can be adopted: A dovetail-shaped protrusion 4-1 is provided on the base of the punching component 4, and a notch matching the dovetail-shaped protrusion 4-1 but with an outer contour size larger than that of the dovetail-shaped protrusion 4-1 is provided on the intermediate seat 5, that is, the dovetail-shaped protrusion 4-1 can swing left and right in the notch; bolt holes are respectively provided on three side surfaces of the intermediate seat 5, and first bolts 5-1, second bolts 5-2, and third bolts 5-3 matching the bolt holes are provided. By screwing the first bolts 5-1, second bolts 5-2, and third bolts 5-3, the heads of them are brought into pressing contact with the dovetail-shaped protrusion 4-1, and the dovetail-shaped protrusion 4-1 can be locked.
[0026] The dovetail-shaped protrusion 4-1 has a dovetail shape on both bilateral outer shapes, that is, Figure 2 as shown, two dovetails symmetrical about the vertical center line of the dovetail-shaped protrusion 4-1. The middle dimension of the cross section of the dovetail-shaped protrusion 4-1 is smaller than the upper and lower dimensions, so as to ensure that it can swing left and right and move back and forth in the notch of the intermediate seat 5 in the horizontal direction, but will not move out of the notch.
[0027] For realizing the cooling of the drilling component: A spray pipe 6 is further provided on the frame 1. The spray pipe 6 is used in matching with the drilling component 2 to spray coolant to the drilling part. The coolant can be water or oil.
