Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting equipment technology, and in particular to an automatic cutting and grinding unit for subframes. Background Technology
[0002] The subframe is an intermediate buffer connecting the car body and suspension. It is a key load-bearing and stress-bearing component of the suspension system. By adjusting the stiffness and flexibility of the subframe, the balance between vehicle comfort and handling can be controlled, thereby ensuring the safety, comfort, and handling of the vehicle. Subframes are classified by material into steel subframes and aluminum alloy subframes. Aluminum alloy subframes are further classified by structural form into low-pressure casting / welded aluminum profiles and integral hollow low-pressure casting, among others.
[0003] During the casting process of the subframe, gating systems and risers are generated. In order to solve the problems of manual cutting, existing technologies also use automatic subframe cutting equipment. However, the existing cutting equipment is carried out in an open space, which generates a lot of noise during the cutting process. The debris generated during the cutting process cannot be automatically collected, resulting in serious pollution of the working environment. Utility Model Content

The cutting chamber has an upper part slide and an lower part slide extending into the cutting chamber on its side. A transfer table is installed on the side of the lower part slide and mounted on the same axis. A first robot and a second robot are respectively installed on both sides of the transfer table. The rotation trajectories of the two robot units intersect and converge at the transfer table. An electrical control cabinet is installed outside the cutting chamber on the side of the lower part slide away from the upper part slide. An oil mist dust collector is installed on the side of the cutting chamber away from the electrical control cabinet.
[0006] Furthermore, both the first and second robots are six-axis robots, and the robots are equipped with grippers for fixing the subframe.
[0007] Furthermore, a high-speed saw and a first saw blade cutting station are provided on the side of the first robot away from the upper slide, and a gripper placement frame is provided between the upper slide and the high-speed saw.
[0008] Furthermore, the upper slide, gripper placement frame, high-speed saw, and first saw blade cutting station are all located on the rotation path of the first robot.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] One embodiment of this utility model is as follows: Figure 1As shown, the cutting chamber 10 has an upper slide 1 and an lower slide 11 extending into its interior. A transfer platform 6 is coaxially mounted on the side of the lower slide 11. A first robot 3 and a second robot 7 are respectively mounted on both sides of the transfer platform 6. The rotation trajectories of the two robot units intersect and converge at the transfer platform 6. An electrical control cabinet 13 is installed outside the cutting chamber 10 on the side of the lower slide 11 away from the lower slide 1. An oil mist dust collector 12 is installed on the side of the cutting chamber 10 away from the electrical control cabinet 13 to purify the oil mist generated during cutting. The cutting chamber keeps the entire system in a closed space, reducing noise generated during the cutting process, ensuring operational safety, and simultaneously enabling the recycling of cutting debris and oil mist.
[0019] Both the first robot 3 and the second robot 7 are six-axis robots. The robots are equipped with grippers for fixing the subframe. The six-axis linkage manipulator can accurately divide the low-pressure casting subframe in the horizontal, vertical and arbitrary angle positions, and achieve one-time accurate cutting of many inlet residues, gates and shrinkage liner on the low-pressure casting subframe.
[0020] The first robot 3 is equipped with a high-speed saw 4 and a first saw blade cutting station 5 on the side away from the upper slide table 1. A gripper placement frame 2 is set between the upper slide table 1 and the high-speed saw 4. The high-speed saw cuts the large-sized runner riser of the sub-frame with a saw blade, and the first saw blade cutting station cuts the more off-center position on the sub-frame with a circular saw blade.
[0021] The upper slide 1, gripper placement frame 2, high-speed sawing machine 4 and first saw blade cutting station 5 are all set on the rotation path of the first robot 3 to grip and transfer the workpiece of the sub-carriage to the high-speed sawing machine and the first saw blade cutting station to cut the sprue riser.
[0022] The second robot 7 is equipped with a second saw blade cutting station 8 and a milling station 9 on the side away from the parting slide 11. The second robot 7 is equipped with a gripper placement rack 2 on the side close to the electrical control cabinet 13. When it is necessary to change the workpiece, the robot gripper is placed, providing an operating platform for changing the new gripper, which is suitable for different workpieces.
[0023] The part ejection slide 11, the second saw blade cutting station 8, the milling station 9 and the gripper placement frame 2 are all set on the rotation path of the second robot 7. The second robot grabs the transfer sub-carriage to the second saw blade cutting station to cut the gating channel and the milling station to grind the gating channel residue.
[0024] like Figure 2 As shown, the second saw blade cutting station 8 has the same structure as the first saw blade cutting station 5, including a support platform 51 and a drive unit 52 fixed on the surface of the support platform 51. The output end of the drive unit 52 is equipped with a detachable saw blade. The output end of the drive unit can meet the installation of saw blades of different specifications, and can also be used to switch between a ray cutting station and a milling station.
[0025] The working principle of this embodiment is as follows: The operator changes the gripper of the robot unit according to the model of the subframe to be processed. The loading slide sends the subframe to the cutting room. After the first robot grabs and fixes it, it moves and passes through the high-speed saw and the first saw blade cutting station to complete the initial cutting. After the cutting is completed, the first robot grabs the subframe and places it on the transfer table. The second robot grabs it and passes through the second saw blade cutting station to complete the cutting at other angles. Then it moves to the milling station to complete the grinding. After the grinding is completed, the subframe is placed on the transfer table and sent out from the output slide.
