Description

Technical Field

[0001] The present invention relates to the technical field of automobile processing, and more specifically, to a combined processing device and a processing method for front and rear bottom plates of an automobile. Background Art

[0002] The chassis of new energy vehicles is provided with a front floor and a rear floor respectively. The front and rear floors can not only protect the chassis from stone impact, scratches and corrosion, but also effectively prevent these damages and extend the service life of chassis-related parts. The front and rear floors can also prevent dirt such as mud, water, and dust from splashing onto key parts of the vehicle chassis, reduce the possibility of component wear and rust, and keep the vehicle chassis clean and dry. The front and rear floors made of steel have good compatibility with other structural parts of the vehicle. In order to make the front and rear floors of the vehicle have the function of energy absorption and buffering, when the vehicle is slightly hit or hits an obstacle, it can absorb part of the energy and reduce the direct impact on the key structural parts of the vehicle, thereby protecting these important parts from damage. Therefore, the hardness of the side of the front and rear floors is not high.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] The chassis of new energy vehicles is provided with a front floor a and a rear floor b. The front floor a and the rear floor b can not only protect the chassis from stone impact, scratches and corrosion, but also effectively prevent these damages and extend the service life of chassis-related parts. The front and rear floors can also prevent dirt such as mud, water, and dust from splashing onto key parts of the vehicle chassis, reduce the possibility of component wear and rust, and keep the vehicle chassis clean and dry. In addition, during the driving process of the vehicle, the front and rear floors can help the vehicle reduce road noise and wind noise and improve the quietness of the vehicle. The materials of the front and rear chassis include steel and resin materials. The front and rear floors of the car are traditionally made of steel through a stamping process. The steel is stamped as a whole and then installed with the subframe by welding or bolting. The front and rear floors made of steel can provide the necessary structural support for the vehicle. The front and rear floors made of steel have good compatibility with other structural parts of the car. In order to make the front and rear floor panels of the car have the function of energy absorption and buffering, when the vehicle is slightly hit or hits an obstacle, it can absorb part of the energy and reduce the direct impact on the key structural components of the vehicle, thereby protecting these important components from damage. The hardness of the side edges of the front floor panel a and the rear floor panel b (i.e., the left side b1 and the right side b2) of the car will not be set too high, and the steel with lower hardness can better absorb the vibration and noise from the road during the vehicle driving, improve the ride comfort, and the front and rear floor panel components made of steel are relatively easy to replace and repair after being damaged, reducing the maintenance cost and complexity. In the prior art, when processing large workpieces such as front and rear floor panels (refer to Fig.11 and Fig.12 ), first fix the workpiece on the turntable, then drive the tool to rotate and move toward the side of the workpiece. When the tool contacts the workpiece, the installation hole can be opened in the workpiece. However, when the tool moves toward the workpiece and drills, pressure will be applied to the workpiece when the tool contacts the workpiece. Since the side of the workpiece is not hard, the pressure applied by the tool to the workpiece will cause the side of the workpiece to deform, which will not only cause errors in the processing size and shape, but also cause abnormal noises when the vehicle is driving due to depressions on the workpiece surface. To solve the above problems, refer to the attached manual. Figures 1 to 6 , Fig.11 and Fig.12A combined processing equipment for the front and rear bottom plates of an automobile comprises a supporting turntable 1 and two position adjustment mechanisms 2, the supporting turntable 1 comprises a supporting station 12, a workpiece is arranged on the supporting station 12, and the supporting station 12 drives the workpiece to rotate with Y as the axis; a drilling mechanism 3 is arranged on the position adjustment mechanism 2, and the drilling mechanism 3 comprises a tool 33, and the position adjustment mechanism 2 drives the tool 33 to move along the X-axis, the Y-axis and the Z-axis, the supporting turntable 1 is located between the two position adjustment mechanisms 2, and the two tools 33 synchronously process the workpiece; a supporting mechanism 4 is arranged on the drilling mechanism 3, and the supporting mechanism 4 comprises a supporting seat 42, and the workpiece is located between the tool 33 and the supporting seat 42, and the supporting seat 42 is parallel to the center line of the tool 33 and coincides with the axis of the tool 33, and the supporting seat 42 fits the workpiece by moving toward the tool 33, and the tool 33 drills the workpiece by rotating and moving toward the supporting seat 42.

[0035] It should be noted that the support seat 42 is hollow, and the diameter of the slot hole inside the support seat 42 is larger than the diameter of the tool 33 .

[0036] It should also be noted that the workpiece to be processed is the front floor panel a or the rear floor panel b of the automobile. At present, in order to meet the lightweight body design, the front and rear floors of the automobile are made of integrated die-casting. The front and rear floors of the automobile are large workpieces. The use of automated equipment for hole opening processing can improve the processing efficiency. The support surface of the support station 12 is designed according to the general shape of the workpiece, and the support station 12 can fully support the bottom of the workpiece.

[0037] The specific implementation scenario is: the workpiece is placed on the support station 12, and the workpiece is fixed on the support station 12. When a hole needs to be drilled on the top of the workpiece, the tool 33 is directly driven to rotate and apply downward pressure to the workpiece. When the left side b1 and the right side b2 of the workpiece are processed, the support station 12 cannot fully support the side of the workpiece due to the complex design of the side of the workpiece. Because the hardness of the left side b1 and the right side b2 of the workpiece is not high, when a horizontal hole is opened on the side of the workpiece, the tool 33 will apply pressure to the side of the workpiece, which may cause The workpiece is deformed, so when the tool 33 is located at the side of the workpiece to be processed, the side of the workpiece is located between the tool 33 and the support seat 42, and then the support seat 42 is driven to move toward the tool 33. When the support seat 42 is in contact with the workpiece, it can provide support for the workpiece, and then the tool 33 is driven to move toward the workpiece. Since the support seat 42 provides support for the workpiece, even if the tool 33 applies pressure to the workpiece, it will not cause deformation of the left side b1 and the right side b2 of the workpiece, which can ensure that the through holes opened on the left side b1 and the right side b2 of the workpiece meet the processing accuracy and design requirements. Compared with the prior art, providing support for the workpiece before drilling can not only prevent the workpiece from being deformed due to processing, but also ensure processing accuracy. Two sets of position adjustment mechanisms 2 and tool 33 are set, and the two sides of the workpiece are processed at the same time, which improves processing efficiency.

[0038] Refer to the instruction manual Figures 1 to 6 When a through hole is formed on the top of the workpiece, since the support station 12 has supported the bottom of the workpiece, there is no need to provide additional support for the workpiece. To facilitate the adjustment of the support seat 42 and prevent the support seat 42 from affecting the normal operation of the tool 33, the drilling mechanism 3 specifically includes a rotating seat 31, on which a second rotating driver 32 is rotatably arranged, and the tool 33 is fixedly arranged on the output shaft of the second rotating driver 32. The support mechanism 4 includes a rotating disk 41, which is rotatably arranged on the second rotating driver 32, on which a third rotating driver 43 is fixedly arranged, on which a gear 431 is fixedly arranged on the output shaft of the third rotating driver 43, and an inner gear ring 411 is fixedly arranged in the rotating disk 41, and the gear 431 meshes with the inner gear ring 411. An adjustment seat 44 is rotatably arranged on the rotating disk 41, a linear driver 3 45 is fixedly arranged on the adjustment seat 44, a guide rail 2 441 is fixedly arranged on the output shaft of the linear driver 3 45, the guide rail 2 441 is slidably arranged with the adjustment seat 44, and the support seat 42 is fixedly arranged on the guide rail 2 441. A rotating driver 4 is fixedly arranged on the rotating disk 41, a mounting groove is opened on the adjustment seat 44, and the output shaft of the rotating driver is fixedly arranged in the mounting groove.

[0039] It should be noted that a motor is fixedly arranged on the rotating seat 31, and the output shaft of the motor is fixedly arranged on the rotating driver 2 32. The rotating driver 2 32 is arranged as a motor, and a drill chuck is fixedly arranged on the rotating driver 2 32, and the tool 33 is fixedly arranged in the drill chuck; the rotating driver 3 43 is arranged as a motor, and the motor is fixedly arranged on the rotating driver 2 32, and the gear 431 is fixedly arranged on the output shaft of the motor; the rotating driver 4 is arranged as a motor, and the motor is fixedly arranged on the rotating disk 41 and its output shaft is fixedly arranged on the adjusting seat 44; the linear driver 3 45 is arranged as a cylinder, and the output shaft of the cylinder is fixedly arranged on the guide rail 2 441.

[0040] It should also be noted that, when the rotary driver 3 43 is started, the rotary drive gear 431 of the output shaft of the rotary driver 3 43 rotates, and the gear 431 meshes with the inner gear ring 411 to drive the rotary disk 41 to rotate. The rotation of the rotary disk 41 can adjust the position of the adjustment seat 44 on the rotary driver 2 32, and the support seat 42 does not need to be supported for drilling holes on the top of the workpiece. When the rotary driver 4 is started, the rotary drive of the output shaft of the rotary driver 4 drives the adjustment seat 44 to rotate, and the rotation of the adjustment seat 44 drives the support seat 42 to rotate along the output shaft of the rotary driver 4 as the center of the circle, so that the support seat 42 is away from the tool 33, and the workpiece can be processed by the tool 33. When the support seat 42 is needed to support the workpiece using the tool 33, the position of the tool 33 is adjusted, and then the linear driver 3 45 is started, and the movement of the output shaft of the linear driver 3 45 drives the support seat 42 to move toward the tool 33, so that the support seat 42 and the workpiece are closely fitted, and the tool 33 is fed toward the workpiece during drilling to drill holes in the workpiece.

[0041] Refer to the instruction manual Figures 1 to 8In order to improve the convenience of assembly and fix the wiring harness rack, guard plate or other accessories, inclined holes need to be opened on both sides and other positions of the front and rear floor of the car. The inclined holes are also used as fixing points for installing shock-absorbing materials or sound insulation pads, which helps to reduce noise, vibration and sound roughness during driving and improve ride comfort. The inclined holes can also help to quickly drain rainwater, snow water and residual water accumulated on the floor when washing the car, reduce water retention, and reduce the risk of corrosion of metal parts. When the inclined holes are opened, an angle will be generated between the support seat 42, the tool 33 and the workpiece. If the support seat 42 is directly used to support the side of the workpiece, the support seat 42 will not be able to fully contact the workpiece to provide stability. If other supporting parts are used directly to support the workpiece, since the inclination angle between the axis of the tool 33 and the workpiece is not determined, the supporting part needs to have a larger coverage area, which will inevitably increase the area of ​​the supporting part. However, the workpiece is relatively complex, and the larger supporting part is not suitable for processing in all positions. In order to solve the above problems, specifically, an auxiliary fitting component 5 is provided on the support seat 42, and the auxiliary fitting component 5 includes an inner cylinder 52, and the inner cylinder 52 is fixedly arranged on the inner side of the support seat 42, and a cavity is provided between the support seat 42 and the inner cylinder 52, and a support rod 51 is slidably arranged in the cavity, and an elastic member 53 is provided between the support rod 51 and the inner wall of the support seat 42.

[0042] It should be noted that the elastic member 53 is configured as a spring, the spring is fixedly arranged with the support rod 51, and one end of the spring away from the support rod 51 is fixedly arranged with the support seat 42. One end of the support rod 51 away from the elastic member 53 is configured as a hemispherical surface, and the configuration of the hemispherical surface can reduce the friction generated when contacting with the workpiece. A groove 1 is provided on the inner wall of the support seat 42, a groove 2 is provided on the inner cylinder 52, and a guide seat is fixedly provided on the support rod 51. The guide seat is slidably arranged in groove 1 and groove 2, and groove 1 and groove 2 cooperate to limit the guide seat, and further limit the displacement of the support rod 51. The number of support rods 51 is set to be multiple, and the number of support rods 51 is adjusted according to usage requirements.

[0043] In this embodiment, the support seat 42 is parallel to the center line of the tool 33 and coincides with the axis of the tool 33. When the tool 33 needs to open an inclined hole on the side of the workpiece, the rotating driver 2 32 drives the tool 33 to rotate. As the rotating driver 2 32 rotates, the support seat 42 will also rotate. When the inclination angle of the tool 33 is adjusted, the support seat 42 is driven to move toward the tool 33. After the support rod 51 contacts the workpiece, when the support rod 51 is subjected to pressure, it will slide into the cavity and cause the elastic member 53 to deform. As the support seat 42 continues to move toward the tool 33, it can ensure that each support rod 51 has a supporting force on the workpiece, and it can also ensure that the support seat 42 is parallel to the center line of the tool 33 and coincides with the axis of the tool 33. There is no need to increase the area of ​​the support seat 42. When the tool 33 opens an inclined hole in the workpiece, the support seat 42 cooperates with the support rod 51 to stably support the workpiece and prevent the workpiece from deforming.

[0044] When a horizontal hole is opened in the workpiece, a support rod 51 can also be used for support. When the tool 33 and the support seat 42 are in a horizontal state, the support seat 42 is driven to move toward the tool 33. After the support rod 51 contacts the workpiece, the support rod 51 slides into the cavity under the action of pressure, and the elastic member 53 is compressed. When the guide seat contacts the inner walls of the slide groove 1 and the slide groove 2, the support rod 51 no longer slides, and then the workpiece is supported by the support rod 51.

[0045] Refer to the instruction manual Figures 1 to 9 The support rod 51 supports the workpiece through the elastic force of the elastic member 53. Since the elastic support has insufficient stability, the elastic support needs to be improved. Specifically, two gas nozzles 54 are fixedly provided on the support seat 42. One of the two gas nozzles 54 is used to introduce gas into the cavity, and the other gas nozzle 54 is used to exhaust the gas in the cavity.

[0046] It should be noted that electronic gas valves are fixedly provided on the two gas nozzles 54 , and an air pump is fixedly provided on one of the two electronic gas valves.

[0047] It should also be noted that the support seat 42 is parallel to the center line of the tool 33 and coincides with the axis of the tool 33, causing an inclination between the tool 33 and the workpiece, driving the support seat 42 to move toward the tool 33. After each support rod 51 contacts the workpiece, before the tool 33 opens a through hole in the workpiece, the air pump delivers gas through the air nozzle 54 to rush air into the cavity. Under the action of air pressure, the support rod 51 can provide stable support for the workpiece. When the tool 33 completes drilling, another air pump is turned on to discharge the gas in the cavity, so that the air pressure in the cavity returns to normal pressure.

[0048] Refer to the instruction manual Figure 1 , Figure 2 and Fig.10In order to stably position the workpiece and ensure the accuracy of the workpiece during processing, and to facilitate driving the workpiece to swing at an angle, so that the two tools 33 can synchronously process the workpiece and improve processing efficiency, specifically, the support turntable 1 includes a fixed seat 11, and a support station 12 is rotatably arranged on the fixed seat 11, and the support station 12 is rotatably arranged on the fixed seat 11. A linear drive 13 is fixedly arranged on the support station 12, and a positioning claw 131 is rotatably arranged on the output shaft of the linear drive 13. The positioning claw 131 vertically positions the workpiece, and a connecting seat 132 is rotatably arranged on the positioning claw 131. The connecting seat 132 is rotatably arranged with the linear drive 13, and a linear drive 2 14 is fixedly arranged on the support station 12, and a positioning claw 2 141 is rotatably arranged on the output shaft of the linear drive 2 14. The positioning claw 2 141 horizontally positions the workpiece.

[0049] It should be noted that a motor is fixedly installed on the fixed seat 11, the output shaft of the motor is fixedly installed on the supporting station 12, the linear drive 13 is configured as a cylinder, the positioning claw 131 is rotatably installed with the output shaft of the cylinder, the linear drive 2 14 is configured as a cylinder, the positioning claw 2 141 is rotatably installed on the output shaft of the linear drive 2 14, and an auxiliary seat is rotatably installed on the linear drive 2 14, and the auxiliary seat and the positioning claw 2 141 are rotatably installed.

[0050] It should also be noted that after the workpiece is placed on the support station 12, the linear drive 13 and the linear drive 2 14 are started, and the movement of the output shaft of the linear drive 13 drives the positioning claw 131 to rotate, and the positioning claw 131 fits with the top of the workpiece to position the workpiece in the vertical direction, and the rotation of the output shaft of the linear drive 2 14 drives the positioning claw 2 141 to rotate, and the positioning claw 2 141 fits with the side of the workpiece to position the workpiece in the horizontal direction, and the workpiece is positioned on the support station 12 by the positioning claw 131 and the positioning claw 2 141, and the rotation of the motor output shaft drives the fixed seat 11 to rotate, and the rotation of the fixed seat 11 drives the workpiece to rotate, thereby achieving the effect of adjusting the inclination angle of the workpiece, which is convenient for processing the workpiece according to usage requirements.

[0051] Refer to the instruction manual Figures 1 to 5 In order to facilitate the adjustment of the position and height of the tool 33, specifically, the position adjustment mechanism 2 includes a crossbeam 21, a rotation driver 211 is fixedly arranged on the crossbeam 21, a threaded rod 212 is fixedly arranged on the output shaft of the rotation driver 211, a saddle 22 is threadedly connected to the threaded rod 212, a support frame 23 is slidably arranged on the saddle 22, and the rotating seat 31 is rotatably arranged at the bottom of the support frame 23.
