Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically a drilling device for the production of automotive exhaust system components. Background Technology

[0002] The vehicle exhaust system is an important component of a vehicle. It is responsible for expelling the exhaust gases produced during engine combustion and reducing the environmental impact of these gases. The vehicle exhaust system includes the exhaust manifold, muffler, and particulate filter, etc. These components need to be connected and installed. During installation, each component needs to have mounting holes made on it using a drilling device.

[0003] Existing drilling devices typically require placing and fixing the component on a processing mold before driving the drilling mechanism to complete the drilling step. However, if the component shifts position on the positioning mold, the drilling position will also shift, affecting the subsequent assembly and fixing of the component. Therefore, we propose a drilling device for the production of automotive exhaust system components. Utility Model Content

[0004] The purpose of this invention is to provide a drilling device for the production of automotive exhaust system components, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for producing automotive exhaust system components, comprising a work plate and an auxiliary positioning mechanism for positioning the components. A support frame is fixedly installed at the bottom of the work plate, and a positioning mold for positioning the components is fixedly installed at the top of the work plate. Drilling mechanisms for drilling holes in the side walls of the components are fixedly installed on both sides of the top of the work plate. A drive mechanism for driving the auxiliary positioning mechanism to move along the "X" axis and the "Z" axis is fixedly installed on the work plate. The auxiliary positioning mechanism is configured in two sets and fixedly installed on one side of the drive mechanism.

[0006] Furthermore, the drilling mechanism includes a first electric slide rail, a first electric slider, a first mounting plate, a first drive motor, and a drilling rod. Two sets of first electric slide rails are fixedly installed on the top of the working plate. The first mounting plate is slidably connected to the first electric slide rails via the first electric slider. Two sets of first drive motors are fixedly installed on the first mounting plate. The output end of the first drive motor is fixedly connected to the drilling rod.

[0007] Furthermore, the driving mechanism includes a second mounting plate, a second electric slide rail, a moving plate, a dual-axis screw, a limiting slide rod, a connecting plate, and a second drive motor. The second mounting plate is fixedly mounted on the top of the working plate. The second electric slide rail is fixedly mounted on one side of the second mounting plate. The moving plate is slidably connected to one side of the second electric slide rail via a second electric slider. The dual-axis screw is rotatably connected to the moving plate. The limiting slide rod is fixedly mounted on the moving plate. Two sets of sliding sleeves are slidably connected to the outside of the limiting slide rod. Two sets of threaded sleeves are threadedly connected to the outside of the dual-axis screw. A connecting plate is fixedly mounted to the outside of the sliding sleeves and threaded sleeves. The second drive motor is fixedly mounted on one side of the moving plate. The output end of the second drive motor is fixedly connected to the dual-axis screw.

[0008] Furthermore, the auxiliary positioning mechanism includes a bearing frame, a positioning block, a locking screw, a clamping ring, and a clearance groove. The bottom of the connecting plate is fixedly connected to the positioning block through the bearing frame. The bottom of the positioning block is fixedly connected to a clamping ring that contacts the outside of the component. The clamping ring has a clearance groove for avoiding the punching rod.

[0009] Furthermore, the positioning block is inserted into the interior of the support frame, and a locking screw that is inserted into the positioning block is provided on one side of the support frame.

[0010] Furthermore, two sets of reinforcing plates made of rigid materials are fixedly installed on the first mounting plate.

[0011] Compared with the prior art, the present invention has the following advantages: The positioning mold set in the present invention can perform preliminary positioning of the parts, and the subsequent drive mechanism can drive the auxiliary positioning mechanism to move along the "X" axis and "Z" axis. This makes it easy to move the auxiliary positioning mechanism onto the parts, so that the auxiliary positioning mechanism can be supported and fitted with the drilling position of the parts. This can prevent the drilling mechanism from causing displacement or shaking when drilling the parts, ensuring the drilling accuracy and making the subsequent installation and fixing more precise.

[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] Please see Figures 1-4 This utility model provides a technical solution: a drilling device for the production of automotive exhaust system components, including a work plate 1 and an auxiliary positioning mechanism 6 for positioning the components. A support frame 2 is fixedly installed at the bottom of the work plate 1, and a positioning mold 3 for positioning the components is fixedly installed at the top of the work plate 1. Drilling mechanisms 4 for drilling holes in the side walls of the components are fixedly installed on both sides of the top of the work plate 1. A drive mechanism 5 for driving the auxiliary positioning mechanism 6 to move along the "X" axis and the "Z" axis is fixedly installed on the work plate 1. The auxiliary positioning mechanism 6 is configured in two sets and fixedly installed on one side of the drive mechanism 5.

[0019] The positioning mold 3 can perform initial positioning of the parts, and the drive mechanism 5 can drive the auxiliary positioning mechanism 6 to move along the "X" and "Z" axes. This allows the auxiliary positioning mechanism 6 to move onto the parts, so that it can fit snugly against the drilling position of the parts. This prevents the drilling mechanism 4 from shifting or shaking when drilling the parts, ensuring the accuracy of the drilling and making subsequent installation and fixing more precise.

[0020] Please see Figure 1 and Figure 2The drilling mechanism 4 includes a first electric slide rail 7, a first electric slider 8, a first mounting plate 9, a first drive motor 10, and a drilling rod 11. Two sets of first electric slide rails 7 are fixedly installed on the top of the working plate 1. The first mounting plate 9 is slidably connected to the first electric slide rail 7 through the first electric slider 8. Two sets of first drive motors 10 are fixedly installed on the first mounting plate 9. The output end of the first drive motor 10 is fixedly connected to the drilling rod 11. Two sets of reinforcing plates 27 made of rigid material are fixedly installed on the first mounting plate 9.

[0021] When it is necessary to drill holes in the parts, the first electric slider 8 moves along the first electric slide rail 7, which drives the first mounting plate 9, the first drive motor 10 and the drilling rod 11 to move towards the part. In this way, the rotating first drive motor 10 can drive the drilling rod 11 to rotate and drill holes.

[0022] Please see Figure 1 , Figure 2 and Figure 3 The driving mechanism 5 includes a second mounting plate 12, a second electric slide rail 13, a moving plate 15, a dual-axis screw 16, a limiting slide rod 17, a connecting plate 20, and a second drive motor 21. The second mounting plate 12 is fixedly installed on the top of the working plate 1. The second electric slide rail 13 is fixedly installed on one side of the second mounting plate 12. The moving plate 15 is slidably connected to one side of the second electric slide rail 13 via a second electric slider 14. The dual-axis screw 16 is rotatably connected to the moving plate 15. The limiting slide rod 17 is fixedly installed on the moving plate 15. Two sets of sliding sleeves 18 are slidably connected to the outside of the limiting slide rod 17. Two sets of threaded sleeves 19 are threadedly connected to the outside of the dual-axis screw 16. The connecting plate 20 is fixedly installed on the outside of the sliding sleeves 18 and the threaded sleeves 19. The second drive motor 21 is fixedly installed on one side of the moving plate 15. The output end of the second drive motor 21 is fixedly connected to the dual-axis screw 16.

[0023] When the auxiliary positioning mechanism 6 needs to move along the "Z" axis, the second electric slider 14 can move up and down along one side of the second electric slide rail 13. This will allow the auxiliary positioning mechanism 6, which is mounted on the drive mechanism 5, to adjust its position along the "Z" axis, so that the auxiliary positioning mechanism 6 can directly contact the two ends of the component. When the auxiliary positioning mechanism 6 needs to move along the "X" axis, the second drive motor 21 drives the dual-axis screw 16 to rotate, which will then drive the threaded sleeve 19 and connecting plate 20 connected to it to move. When the connecting plate 20 moves, it can be limited by the limiting slide rod 17 and the sliding sleeve 18 to ensure the stable movement of the auxiliary positioning mechanism 6.

[0024] Please see Figure 1 , Figure 2 and Figure 4 The auxiliary positioning mechanism 6 includes a support frame 22, a positioning block 23, a locking screw 24, a clamping ring 25, and a clearance groove 26. The bottom of the connecting plate 20 is fixedly connected to the positioning block 23 through the support frame 22. The bottom of the positioning block 23 is fixedly connected to the clamping ring 25, which contacts the outside of the component. The clamping ring 25 has a clearance groove 26 for avoiding the punching rod 11. The positioning block 23 is inserted into the interior of the support frame 22. A locking screw 24 inserted into the positioning block 23 is provided on one side of the support frame 22.

[0025] When the auxiliary positioning mechanism 6 moves with the drive mechanism 5, the clamping ring 25 can directly contact the outside of the component, so that the positioning of the component can be completed by the clamping ring 25. The clearance groove 26 can prevent the drilling rod 11 from affecting the drilling of the drilling rod 11 when it is working. When the clamping ring 25 needs to be replaced, the locking screw 24 is taken out from the inside of the positioning block 23, so that the corresponding clamping ring 25 can be replaced. The positioning block 23 on the clamping ring 25 is then reinserted into the bearing frame 22 and reinstalled and fixed by the locking screw 24.

[0026] In use, the positioning mold 3 firstly positions the parts. Then, the drive mechanism 5 moves the auxiliary positioning mechanism 6 along the X and Z axes, facilitating its movement onto the parts. This ensures the auxiliary positioning mechanism 6 is properly aligned with the drilling position on the parts, preventing displacement or wobbling during drilling by the drilling mechanism 4 and guaranteeing drilling accuracy. This makes subsequent installation and fixing more precise. When drilling is required, the first electric slider 8 moves along the first electric slide rail 7, driving the first mounting plate 9, the first drive motor 10, and the drilling rod 11 towards the parts. The rotating first drive motor 10 then rotates the drilling rod 11 to drill holes. When the auxiliary positioning mechanism 6 needs to move along the Z axis, the second electric slider 14 moves up and down along the second electric slide rail 13, thus moving the auxiliary positioning mechanism 6 mounted on the drive mechanism 5. Adjusting along the "Z" axis position allows the auxiliary positioning mechanism 6 to directly contact both ends of the component. When the auxiliary positioning mechanism 6 needs to move along the "X" axis, the second drive motor 21 drives the dual-axis screw 16 to rotate, which in turn drives the threaded sleeve 19 and connecting plate 20 connected to it to move. When the connecting plate 20 moves, it can be limited by the limiting slide rod 17 and the sliding sleeve 18 to ensure the stable movement of the auxiliary positioning mechanism 6. When the auxiliary positioning mechanism 6 moves with the drive mechanism 5, the clamping ring 25 can directly contact the outside of the component, thus enabling the positioning of the component. The clearance groove 26 prevents the drilling rod 11 from affecting the drilling of the drilling rod 11. When the clamping ring 25 needs to be replaced, the locking screw 24 is removed from inside the positioning block 23, allowing the corresponding clamping ring 25 to be replaced. The positioning block 23 on the clamping ring 25 is then reinserted into the bearing frame 22 and reinstalled and fixed using the locking screw 24.
