Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and in particular to a drilling equipment for processing new energy vehicle frames. Background Technology

[0002] In the field of new energy vehicle manufacturing, drilling of the chassis frame is one of the key processes. Currently, CNC laser cutting machines are mostly used for drilling the chassis frame. However, because new energy vehicle chassis frames are usually large and heavy, the loading and unloading processes face many inconveniences in actual processing.

[0003] In the traditional method, moving the chassis to the workbench is not only physically demanding for workers, but also difficult to control precisely, resulting in low loading and unloading efficiency. Furthermore, to ensure drilling accuracy, a tedious tooling positioning operation is required after each loading and unloading, further increasing time costs and reducing overall processing efficiency.

[0004] Meanwhile, the lack of effective limiting and centering devices during the vehicle frame positioning process makes it difficult to ensure the accurate position of the vehicle frame on the workbench, which in turn affects the accuracy of drilling and may lead to problems such as mismatch between the hole positions and the battery tray, which has an adverse impact on the assembly quality of new energy vehicles. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drilling device for processing new energy vehicle frames, which solves some of the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a drilling device for processing new energy vehicle frames, including a CNC laser cutting machine. A positioning plate is placed on the worktable of the CNC laser cutting machine. A support shaft is rotatably installed on the lower end of the positioning plate near both the front and rear ends. Double conical rollers are fixedly installed on both the left and right ends of the support shaft. Slopes are fixedly installed on both the front and rear ends of the CNC laser cutting machine. Tracks are fixedly installed on the slopes and on the worktable of the CNC laser cutting machine near both the left and right sides. The tracks are adapted to the double conical rollers. Slide grooves are provided on both the left and right ends of the positioning plate near the corners. Square bearings are slidably installed inside the slide grooves. Bidirectional lead screws are fixedly installed between the square bearings. Two sets of symmetrical moving blocks are threaded onto the bidirectional lead screws. Angle abutments are fixedly connected to the moving blocks at their closest ends.

[0007] Furthermore, the left end of each bidirectional lead screw is equipped with a square bearing and a handwheel for easy operation to rotate the bidirectional lead screw.

[0008] Furthermore, a fixed block is rotatably sleeved on the middle of each bidirectional lead screw, and a screw is threaded through and connected to the middle of both ends of the positioning plate. The screw is rotatably connected to the fixed block, and a rotating wheel is fixedly installed on the end of the screw away from the fixed block, so as to realize the pushing and adjustment operation of the diagonal abutment and other structures.

[0009] Furthermore, L-shaped baffles are slidably installed on the worktable of the CNC laser cutting machine near the middle of both the front and rear ends. The L-shaped baffles fit against the positioning plate and work with the track to achieve the purpose of centering and positioning.

[0010] Furthermore, two sets of return springs are symmetrically installed on the lower end face of the L-shaped baffle, and the upper end of each return spring is fixedly connected to the worktable of the CNC laser cutting machine, which is simple in structure and easy to use.

[0011] Furthermore, each of the fixed blocks is equipped with a guide rod that passes through and is fixedly installed. The left and right ends of the guide rod pass through and are slidably connected inside the moving block. The left and right ends of the guide rod are fixedly connected to the square bearing to limit the movement of the moving block and ensure the rationality of the structural design.

[0012] The advantages of this utility model are as follows:

[0013] 1. This equipment, through the combination of double conical rollers and a track, allows workers to move the positioning plate to the worktable more quickly and effortlessly during loading and unloading by pushing the positioning plate with the help of the double conical rollers. The track also limits and guides the positioning plate, ensuring it is accurately centered on the worktable. Simultaneously, the chassis frame of the same batch can be pre-fixed on another set of positioning plates. After the first set of holes is drilled, loading and unloading can be quickly achieved, avoiding the need for cumbersome tooling positioning operations after lifting it to the worktable. This effectively reduces loading, unloading, and positioning time, and improves the efficiency of the overall processing flow.

[0014] 2. By using a bidirectional lead screw to drive the corner abutments to move symmetrically against the four corners of the chassis frame, the frame is initially limited and fixed. Then, the L-shaped baffle automatically rises after the positioning plate moves into place to form a clamping fixation, further preventing the frame from shifting during the drilling process. This dual positioning method ensures the stability and centered positioning effect of the frame on the worktable, improves the drilling accuracy of the CNC laser cutting machine, and provides a reliable guarantee for the processing quality of new energy vehicle frames. The structure is simple, the operation is flexible, and the integrity and rationality of this solution are guaranteed. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-4 A drilling device for processing new energy vehicle frames includes a CNC laser cutting machine 1. A positioning plate 2 is placed on the worktable of the CNC laser cutting machine 1. Support shafts 3 are rotatably mounted on the lower end of the positioning plate 2 near both the front and rear ends. Double conical rollers 4 are fixedly mounted on both the left and right ends of the support shafts 3. Slope plates 5 are fixedly mounted on both the front and rear ends of the CNC laser cutting machine 1. Rails 6 are fixedly mounted on the slope plates 5 and on both the left and right sides of the worktable of the CNC laser cutting machine 1, and the rails 6 are compatible with the double conical rollers 4. Slide grooves 7 are provided on both the left and right ends of the positioning plate 2 near the corners. Square bearings 8 are slidably mounted inside the slide grooves 7. Bidirectional lead screws 9 are fixedly mounted inside the square bearings 8, and two sets of phase-connected screws 9 are threaded onto each bidirectional lead screw. Symmetrical moving blocks 10, with corner abutments 11 fixedly connected to each other at their adjacent ends. The design of double conical rollers 4 not only facilitates the movement of the positioning plate 2 by the worker, but also makes it easier and faster for the worker to push the positioning plate 2 from the slope plate 5 onto the worktable after aligning the double conical rollers 4 with the track 6. This facilitates loading and unloading. When drilling by turning on the CNC laser cutting machine 1, the chassis frame of the same batch can be fixed on another set of positioning plates 2 in advance, so that the loading and unloading can be carried out quickly after the drilling operation is completed, and there is no need to position the chassis frame with tooling, saving time and greatly improving processing efficiency. In addition, the track 6 can play a limiting role, so that the positioning plate 2 is in the center position on the worktable.

[0022] Please see Figures 1-4 The left end of the bidirectional lead screw 9 is pierced by a square bearing 8 and a handwheel 12 is fixedly installed thereon. A fixing block 13 is rotatably sleeved on the middle of the bidirectional lead screw 9. Screws 14 are threaded through and connected to the middle of both ends of the positioning disc 2. Screws 14 are rotatably connected to the fixing blocks 13. A rotating wheel 15 is fixedly installed on the end of the screw 14 away from the fixing blocks 13. L-shaped baffles 16 are slidably installed on the worktable of the CNC laser cutting machine 1 near the middle of both ends. The L-shaped baffles 16 are all connected to… The positioning discs 2 are fitted together. Two sets of return springs 17 are symmetrically installed on the lower end face of each L-shaped baffle 16. The upper ends of the return springs 17 are fixedly connected to the worktable of the CNC laser cutting machine 1. Guide rods 18 are threaded through and fixedly installed on each fixed block 13. The left and right ends of the guide rods 18 are threaded through and slidably connected inside the moving block 10. The left and right ends of the guide rods 18 are fixedly connected to the square bearing 8. The chassis of the new energy vehicle is placed inside the positioning discs 2. The handwheel 12 can be rotated to... The bidirectional lead screw 9 rotates, which in turn causes the moving block 10 to move the corner abutment 11 symmetrically. The rotating wheel 15 drives the screw 14 to rotate, which in turn drives the fixing block 13 to move the bidirectional lead screw 9 and other structures synchronously. This allows the corner abutment 11 to abut against the four corners of the chassis frame, thus limiting and fixing it and preventing displacement during subsequent drilling operations that could lead to mismatch between the hole and the battery tray. It is worth mentioning that during the process of moving the upper and lower positioning plates 2, the corresponding L-shaped baffles 16 need to be pressed down to avoid obstructing the path of the positioning plates 2. When the positioning plates 2 abut against another set of L-shaped baffles 16, they stop. Under the reset action of the return spring 17, the pressed L-shaped baffles 16 will automatically rise, thus forming a clamping and fixing effect on the positioning plates 2 through the two sets of L-shaped baffles 16. This further prevents displacement during drilling and also serves to center the positioning plates 2 and the chassis frame, ensuring the drilling accuracy of the CNC laser cutting machine 1.

[0023] Working principle: In use, the chassis of the new energy vehicle is first placed inside the positioning plate 2. Turning the handwheel 12 drives the bidirectional lead screw 9 to rotate. The rotation of the bidirectional lead screw 9 causes the moving block 10 to move the corner abutment 11 symmetrically. Turning the rotating wheel 15 drives the screw 14 to rotate. The rotation of the screw 14 causes the fixing block 13 to move the bidirectional lead screw 9 and other structures synchronously. This allows the corner abutment 11 to abut against the four corners of the chassis frame, limiting and fixing it to prevent displacement during subsequent drilling operations, which could lead to mismatch between the hole positions and the battery tray. The design of the double conical rollers 4 not only makes it easier for workers to push the positioning plate 2, but also makes it easier and faster for workers to push the positioning plate 2 from the ramp 5 onto the worktable after aligning the double conical rollers 4 with the track 6, facilitating loading and unloading. When drilling with the CNC laser cutting machine 1, the chassis frame of the same batch can be pre-fixed on another set of positioning plates 2. This allows for rapid loading and unloading after drilling, eliminating the need for tooling positioning of the chassis frame. Additionally, the track 6 acts as a limit, keeping the positioning plate 2 centered on the worktable. Notably, during the loading and unloading of the positioning plate 2, the corresponding L-shaped baffles 16 need to be pressed down to avoid obstructing the path of the positioning plate 2. The positioning plate 2 stops when it reaches the other set of L-shaped baffles 16. Under the reset action of the return spring 17, the pressed L-shaped baffles 16 automatically rise, thus clamping and fixing the positioning plate 2 with the two sets of L-shaped baffles 16, further preventing displacement during drilling.
