Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and specifically to a processing device for the motor housing of a new energy vehicle. Background Art

[0002] The development of new energy vehicles relies on technological innovation and the optimization of core components. Among them, the motor housing, as the "heart protector", has become the key to promoting vehicle lightweight and high efficiency through material selection, process upgrading, and function strengthening. In the future, with the breakthroughs in battery technology and manufacturing processes, new energy vehicles and their supporting industrial chains will have a broader development space. With the rise of fields such as new energy and intelligent manufacturing, lightweight, high-protection, and intelligent housing technologies will become the core competitive points, driving the motor system to evolve towards a more efficient and reliable direction;

[0003] The invention patent with the application number 202311486277.5 discloses a drilling device for a motor housing. By setting a clamping component, it can automatically clamp and fix the motor housing when the driving motor starts, and synchronously release the clamping and fixing of the motor housing when the drilling process of the motor housing is completed and the driving motor is turned off, without the need for manual additional manipulation or operation to release and fix the motor housing, which is convenient to use and improves work efficiency. However, in actual use, we found that although this method can quickly and automatically position the motor housing, it can still only process a single motor housing during the drilling process, and still requires staff to repeatedly pick up and place, resulting in the drilling efficiency of the motor housing being affected;

[0004] The invention patent with the application number 202410636070.X discloses a processing device for a click housing. Through two concentric positioning circular bosses symmetrically coaxial, and combined with the guide rod connected between the fixed plate and the moving plate, it ensures the stable concentric coaxiality of the motor housing placed between the two concentric positioning circular bosses; realizes the structural function of multi-station synchronous processing, improves the processing efficiency of turning holes and threading of the motor housing, enhances the high precision of concentric coaxial processing, is convenient for drilling and tapping the peripheral parts of the motor housing, and meets the high-efficiency processing requirements for completing the motor housing all at once; through the negative pressure adsorption of the outer port of the adsorption channel and the inner wall of the motor housing to be fixed together, preventing the secondary movement of the positioned and placed motor housing and strengthening the firmness of the installation connection. However, during the process of drilling and tapping, although this method realizes the structural function of multi-station synchronous processing, it can only process one housing at a time. After completing the processing of one housing, it still needs to be repeatedly picked up to achieve the purpose of replacing the housing to be processed, resulting in the lack of continuity in the entire processing process and thus affecting the processing efficiency;

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1-10 The present invention provides a technical solution: a new energy vehicle motor housing processing device, including a workbench 1, a drilling station 2, a tapping station 3 and a housing body 4, and also includes

[0037] The support plate 5 is arranged above the workbench 1. There are three bases 6 arranged above the support plate 5, and the three bases 6 respectively correspond to the drilling station 2, the tapping station 3 and the installation position of the casing body 4.

[0039] The power assembly 10 is arranged below the support plate 5. A feeding conveyor belt 14 is arranged on one side of the workbench 1, and a blanking window 15 is opened on one side of the workbench 1.

[0040] Using the power generated by the power assembly 10 to drive the three rectangular blocks 9 to slide in the sliding groove 8, driving the bases 6 and the rubber rollers 7 to move synchronously, and driving the casing bodies 4 located on the three bases 6 to reach one end of the feeding conveyor belt 14, the drilling station 2 and the tapping station 3 respectively, and passing through the blanking window 15.

[0041] By using the inward clamping of the rubber rollers 7 on both sides of the base 6 and the friction force between it and the casing body 4, the casing body 4 is driven to be in the central position of the base 6 during the feeding process.

[0042] Electric push rods 16 are arranged on both the support plate 5 and above the workbench 1, and the two electric push rods 16 are respectively located on one side of the drilling station 2 and the tapping station 3. The output ends of the two electric push rods 16 are both provided with pressing plates 161, and rubber plates 162 are arranged at the ends of the two pressing plates 161 far away from the two electric push rods 16.

[0043] The support plate 5 is an equilateral triangle, and the sliding groove 8 opened on the support plate 5 has the same shape as the support plate 5.

[0044] The power assembly 10 includes a driving member 11 arranged in the workbench 1. Using the driving member 11 to generate power to drive the three bases 6 to slide on the support plate 5. A transmission member 12 is arranged on the workbench 1 to transmit the power required for the sliding of the three bases 6. A traction member 13 is arranged below the support plate 5 to guide the moving direction of the three bases 6.

[0045] The driving member 11 includes a driving motor 111 arranged in the workbench 1. A driving gear 112 is arranged at the output end of the driving motor 111. Three transmission gears 113 are rotatably arranged between the support plate 5 and the workbench 1 through a rotating shaft, and the driving gear 112 meshes with one of the three transmission gears 113.

[0046] The transmission member 12 includes a transmission belt 121 disposed outside the three transmission gears 113. A plurality of tooth grooves 122 are formed in the transmission belt 121, and the three transmission gears 113 are all engaged with the plurality of tooth grooves 122.

[0047] The traction member 13 includes three traction plates 131 rotatably disposed on the transmission belt 121. Opposite ends of the three traction plates 131 are rotatably disposed at the bottom of adjacent rectangular blocks 9.

[0048] Clamping shafts 17 are rotatably disposed on both sides of the base 6. Clamping torsion springs 18 are disposed at the bottoms of the two clamping shafts 17. The other ends of the two clamping torsion springs 18 are disposed on the base 6. Clamping plates 19 are disposed outside the two clamping shafts 17. A control shaft 20 is rotatably disposed at one end of the clamping plate 19 away from the clamping shaft 17. The rubber roller 7 is disposed outside the corresponding control shaft 20. Stop bars 25 are disposed on both sides of the base 6 and are used in cooperation with the two clamping plates 19.

[0049] A ratchet 21 is disposed at the top of the control shaft 20. An auxiliary shaft 22 is rotatably disposed on the clamping plate 19. A ratchet tooth 23 that cooperates with the ratchet 21 is disposed outside the auxiliary shaft 22. A return torsion spring 24 is disposed at the bottom of the auxiliary shaft 22, and the other end thereof is disposed on the clamping plate 19.

[0050] A plurality of limiting plates 141 are equidistantly disposed on the loading conveyor belt 14. The plurality of limiting plates 141 are respectively attached to one side of the corresponding machine housing body 4 away from the workbench 1. The loading conveyor belt 14 is slightly higher than the three bases 6.

[0051] During use, when a worker needs to drill and tap the machine housing body 4, the machine housing body 4 is placed on the loading conveyor belt 14, and the machine housing body 4 is respectively located between the plurality of limiting plates 141. The machine housing body 4 moves with the loading conveyor belt 14 and enters the nearest base 6 to the loading conveyor belt 14. During the process of the machine housing body 4 entering the base 6, it will first contact the two rubber rollers 7 and squeeze the two rubber rollers 7, causing the two rubber rollers 7 to rotate. Please refer to the accompanying drawings. Figure 9 After the two rubber rollers 7 are squeezed, the clamping plate 19 connected to the rubber roller 7 through the control shaft 20 will rotate through the clamping shaft 17 at its other end. When the clamping shaft 17 rotates, the clamping torsion spring 18 disposed at the bottom of the clamping shaft 17 starts to store energy. At this time, the two rubber rollers 7 will rotate during the process of being squeezed, as shown in the accompanying drawings of the specification. Figure 9As shown in the figure, under the action of the ratchet 21 and the ratchet teeth 23, the rubber roller 7 on the left can only rotate counterclockwise, while the rubber roller 7 on the right can rotate clockwise, so that after the rubber roller 7 clamps the casing body 4, under the action of the friction force of the two rubber rollers 7 and the unidirectional rotation, the casing body 4 can only move in a single direction and cannot move in the direction of the upper material conveyor belt 14, ensuring that the casing body 4 is always located at the center of the base 6 when following the movement of the base 6, so that during the movement of the base 6, the casing body 4 is kept under the clamping action. The casing body 4 is kept stable to avoid the displacement of the casing body 4 due to vibration. When the casing body 4 reaches the drilling station 2, the electric push rod 16 can cooperate with the base 6, so that the casing body 4 will not collide and rub with the inner side of the base 6, ensuring the accuracy of drilling and tapping operations while avoiding the casing body 4 from being scratched and painted, thereby improving the processing efficiency while ensuring the integrity of the casing body 4. The two stop rods 25 arranged on the base 6 can control the distance between the two rubber rollers 7 to be not too far away when there is no casing body 4 on the base 6. The housing body 4 is not too small, so that the housing body 4 can smoothly enter between the two rubber rollers 7 during the entry process, and the two rubber rollers 7 can avoid maintaining the clamping force on the housing body 4. When the housing body 4 completes the drilling operation, the electric push rod 16 near the drilling station 2 is retracted, and the base 6 drives the housing body 4 to continue to move to the tapping station 3, and then the electric push rod 16 near the tapping station 3 is extended to fix the housing body 4 to ensure the accuracy of the tapping operation. The rubber plates 162 respectively arranged on one side of the two extrusion plates 161 can When the casing body 4 is squeezed, a buffer is provided to reduce wear. When the casing body 4 completes the tapping operation, the electric push rod 16 is retracted. At this time, the staff can extract the casing body 4 upward from the base 6 of the tapping station 3 through the unloading window 15, so that the casing body 4 after processing is separated from the base 6, and then reciprocatingly circulates. The three bases 6 perform drilling and tapping operations alternately at their respective stations, ensuring seamless connection of the production process and efficient operation. The entire process is automated and efficient, ensuring the simultaneous improvement of product quality and production speed;

[0052] When the staff needs to drill and tap the casing body 4 and turn on the drive motor 111, the drive motor 111 will control the drive gear 112 at its output end to rotate. During the rotation of the drive gear 112, it will drive the meshing transmission gear 113 to rotate. Under the action of the transmission belt 121 and multiple tooth grooves 122, the three transmission gears 113 rotate synchronously. When the transmission gear 113 drives the transmission belt 121 to move through the tooth grooves 122, the traction plate 131 rotatably arranged on the transmission belt 121 will move along with the movement of the transmission belt 121. And the rectangular block 9 rotatably arranged on the traction plate 131 will slide in the sliding groove 8 following the traction plate 131 under the action of the traction plate 131, so that the rectangular block 9 drives the base 6 on its top to move. At the same time, due to the polygonal characteristics of the rectangular block 9, when the rectangular block 9 slides in the sliding groove 8, the base 6 is always kept from changing its surface during the movement, so that the casing body 4 above the base 6 maintains the correct angle and position, avoiding the deflection of the surface to be drilled and tapped during the processing, resulting in mistakes in the drilling and tapping operations. Through this precise mechanical control, the casing body 4 can be smoothly converted between different workstations, and seamless connection is achieved between each process, thus greatly improving the processing efficiency of the casing body 4 and ensuring the continuity and high efficiency of the entire processing flow.
