[0003] In the past, the safety of new energy powertrain housings was ensured by design at the finished powertrain stage. Currently, there is no safety treatment during the initial mechanical processing of the housing.

Burrs are those that can be broken by the lead. If they are not removed thoroughly, they will fall into the powertrain during the assembly of the new energy powertrain housing, causing safety accidents and damage to the assembly, resulting in economic losses and reduced production efficiency. The existing deburring devices on the market cannot be used to process new energy powertrain housings. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model is described in detail below in conjunction with the accompanying drawings:

[0026] A new energy powertrain housing safety processing device is used to remove burrs generated during processing on cross holes, edges and surfaces of new energy vehicle powertrain housing workpieces, including a vertically arranged mounting plate 16 of a plate-like structure, a plurality of motors 14 whose axes of output shafts are arranged in the front-to-back direction and are perpendicular to the plane where the mounting plate 16 is located are fixedly arranged on the rear surface of the mounting plate 16, a rotating shaft 2 is arranged directly below each motor 14 and passes through the mounting plate 16 and is driven by the corresponding motor 14 to rotate along the axis in the front-to-back direction, a brush 12 for removing burrs is fixedly arranged at the front end of each rotating shaft 2, the front part of all rotating shafts 2 passes through a brush guide plate 11 so that the brush 12 extends from the front end surface of the brush guide plate 11, the brush guide plate 11 is fixedly connected to the front end of a cylinder guide rod 10 whose axis is arranged in the front-to-back direction and passes through the mounting plate 16, and the rear end of the cylinder guide rod 10 passes through the mounting plate 16 and is connected to a guide support fixed on the rear surface of the mounting plate 16.

The guide support cylinder 13 drives the cylinder guide rod 10 to move forward and backward, drives the brush guide plate 11 to move forward and backward, and then makes the brush 12 extend and retract from the brush guide plate 11. There is an anti-collision sensor 5 fixedly arranged on the rear surface of the mounting plate 16 behind the rear end of each rotating shaft 2. A spring pull rod 8 is arranged between the two sides of the rear end of each rotating shaft 2 and the rear surface of the mounting plate 16. When the workpiece to be deburred is driven by an external robot and placed in a pre-fixed working position, if there is a deviation in the position where the workpiece is placed, causing the brush 12 to contact the end face of the workpiece, the brush 12 is forced to drive the rotating shaft 2 to move backward so that the end of the rotating shaft 2 contacts the contact of the anti-collision sensor 5, then the motor 14 will not drive the rotating shaft 2 and the brush 12 to rotate, thereby protecting the workpiece. When the brush 12 no longer contacts the end face of the workpiece, the restoring force of the spring pull rod 8 drives the rotating shaft 2 to return to its original position.

[0027] In this embodiment, the housing of the motor 14 is fixed to the rear surface of the mounting plate 16 through a motor mounting seat 23 of a rectangular frame structure whose top surface, bottom surface and middle portion are all hollowed out. The front surface of the motor mounting seat 23 is fixedly connected to the rear surface of the mounting plate 16. The output shaft of the motor 14 passes through the rear surface of the motor mounting seat 23 and is fixedly connected to the center hole of a driving synchronous wheel 7 located in the hollow portion in the middle of the motor mounting seat 23. The driving synchronous wheel 7 is connected to a driven synchronous wheel 3 located below the motor 14 through a toothed transmission belt 6. The center hole of the driven synchronous wheel 3 is fixedly fixed to a rotating shaft connecting sleeve. On the outer wall of the cylinder 22, the rotating shaft connecting sleeve 22 is sleeved on the middle and rear part of the rotating shaft 2 through two rotating shaft sliding bearings 4. The rear end of the rotating shaft 2 is fixedly connected to the inner ring of a third rotating shaft bearing 20 installed in the bearing seat 21. The bearing seat 21 is fixedly connected to the middle part of a rotating shaft clamping plate 15 with a cross-shaped plate structure. The lower end gap of the vertical part of the rotating shaft clamping plate 15 is set in front of the contact of the anti-collision sensor 5. Both ends of the horizontal part of the rotating shaft clamping plate 15 are fixedly connected to the rear end of the corresponding spring pull rod 8, and the front end of the spring pull rod 8 is fixedly connected to the rear surface of the mounting plate 16.

[0028] In this embodiment, the front portion of the rotating shaft connecting sleeve 22 is arranged in a rotating shaft sleeve 18, the front end of the rotating shaft connecting sleeve 22 is fixed on the mounting plate 16, the rotating shaft sleeve 18 is fixedly mounted on the rear surface of the mounting plate 16, and the rotating shaft sleeve 18 and the rotating shaft connecting sleeve 22 are provided with a first rotating shaft bearing 1 and a second rotating shaft bearing 19.

[0029] In this embodiment, at least two sliding guide rods 9 are arranged between the brush guide plate 11 and the mounting plate 16 to provide guidance for the brush guide plate 11 when it moves forward and backward.

[0030] In this embodiment, the front end of the sliding guide rod 9 is fixedly connected to the brush guide plate 11 , and the rear end of the sliding guide rod 9 is slidably connected to the mounting plate 16 .

[0031] Alternatively, the front section of the sliding guide rod 9 is slidably connected to the brush guide plate 11 , and the rear end of the sliding guide rod 9 is fixedly connected to the mounting plate 16 .

[0032] In this embodiment, a brush sleeve 17 is sleeved on the outside of the brush 12 , and the base of the brush sleeve 17 is fixed on the front end surface of the brush guide plate 11 . The brush sleeve 17 provides better guidance for the forward and backward movement of the brush 12 .

[0033] The working principle and working process of a new energy powertrain housing safety processing device provided by the utility model are as follows:

[0034] Power mechanism: The output shaft of each motor is equipped with a driving synchronous wheel 7, and is fixed on the rear surface of the mounting plate 16 through a motor mounting seat 23, and is connected to the driven synchronous wheel 3 below through a toothed transmission belt 6. The driven synchronous wheel 3 is connected to the rotating shaft 2 through a rotating shaft connecting sleeve 22. The front end of the rotating shaft 2 is equipped with different types of brushes 12 according to needs, so that the brush 12 can be driven to rotate by the motor 14 to remove burrs. In order to ensure high-speed rotation, multiple rotating shaft bearings are installed on the rotating shaft 2. In order to reduce the friction between the rotating shaft 2 and the mounting plate 16, a rotating shaft connecting sleeve 22 is installed between the mounting plate 16 and the rotating shaft 2.

[0035] Guide support mechanism: The guide support mechanism mainly completes the positioning and guiding of the rotating shaft 2. The extension of the guide support cylinder 13 that reciprocates in the front and rear directions drives the cylinder guide rod 10 to extend and then drives the brush guide plate 11 to extend. After positioning is completed, the guide support cylinder 13 retracts, and the motor 14 rotates to drive the rotating shaft 2 and the brush 12 to work.

[0036] Anti-collision mechanism: When the workpiece to be deburred is not placed in a completely accurate position, and the brush 12 collides with the end face of the workpiece that does not need to be deburred, the brush 12 and the rotating shaft 2 are subjected to a backward force, and the rotating shaft 2 is displaced radially (in the front and rear direction) backward through the rotating shaft sliding bearing 4, so that the cross-shaped rotating shaft clamping plate 15 moves backward and contacts the contact point of the touch sensor 5. At this time, the collision touch sensor 5 generates an electrical signal, and the motor 14 stops rotating. The cross rotating shaft clamping plate 15 is pressed against the rotating shaft 2 by the tension generated by the spring pull rods 8 on both sides. When subjected to external force, the spring pull rods 8 are stretched and have a tendency to rebound (retract forward).

[0037] Place the workpiece with burrs to be processed at a fixed position in a pre-set deburring area, and the guide support mechanism will play a role. The guide support cylinder 13 will drive the cylinder guide rod 10 to extend, and drive the brush guide plate 11 to extend. The main function of this action is to prevent the brush 12 from swinging up and down and left and right, and to guide and position before removing burrs. Because the rotating shaft 2 is relatively long, the guiding effect of the extension of the cylinder guide rod 10 and the brush guide plate 11 can reduce the bending deformation of the rotating shaft 2. The device is designed with a collision alarm to ensure the integrity of the workpiece and equipment. When the position of the workpiece to be deburred is not completely accurate, and the brush 12 collides with the end face of the workpiece that does not need to be deburred, the anti-collision mechanism comes into play. The brush 12 is provided with a guide protection device, namely a brush sleeve 17. The brush 12 and the rotating shaft 2 are subjected to a backward force, and the rotating shaft 2 is displaced backward through the rotating shaft sliding bearing 4, so that the cross-shaped rotating shaft clamping plate 15 moves backward and contacts the contact point of the touch sensor 5. At this time, the anti-collision sensor 5 sends a signal, and the device will stop moving, directly protecting the product from economic losses caused by collision and high-speed rotation of the brush 12. To reset after the collision, it is only necessary to move the workpiece to be processed and then separate the device from the workpiece. The spring pull rod 8 will rebound, so that the cross-shaped rotating shaft clamping plate 15 moves forward and drives the rotating shaft 2 and the brush 12 to complete the reset.

[0038] If the positioning is accurate, the power mechanism works, the guide support cylinder 13 drives the cylinder guide rod 10 to retract and then drives the brush guide plate 11 to retract, the brush 12 is exposed from the brush sleeve 17 and enters the part of the workpiece where the burrs are to be removed, the motor 14 drives the active synchronous wheel 7, drives the driven synchronous wheel 3 through the transmission belt 6 to drive the rotating shaft brush 12 to rotate, and the rotating shaft 2 is rotated rapidly through the three rotating shaft bearings. At the same time, the robot will drive the new energy powertrain housing to change its trajectory and posture to cooperate to complete the entire product burr processing process. The multiple brushes at the front end can handle cross-hole burrs, surface burrs, edge burrs, etc., which can be completed at one time when the new energy powertrain housing is cleaned, thereby improving production efficiency. The processed new energy powertrain housing improves the product qualification rate and product reliability, and reduces enterprise costs.
