DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Embodiment, a device for automatically cleaning burrs in the processing of a car door lock sleeve, the implementation structure refers to Figure 1-7 As shown, the device is used for Figure 8 The automobile door lock sleeve shown is processed.

[0021] according to Figure 1-7 The equipment includes a frame 2, a workbench 3 is provided in the middle of the frame 2, and a bottom plate is provided at the bottom; it also includes a deburring mechanism and a lock sleeve moving component provided on the workbench 3, and the lock sleeve moving component is provided below the deburring mechanism; the workbench 3 is provided with a lock sleeve drop-out opening 31 below the middle of the lock sleeve moving component, and a turnover box 4 placed on the bottom plate is provided below the lock sleeve drop-out opening 31. The lock sleeve to be processed is manually placed in the lock sleeve moving component, and after the deburring mechanism removes the burrs from the lock sleeve, the lock sleeve moving component releases the lock sleeve, and the lock sleeve falls from the lock sleeve drop-out opening 31 and is collected in the turnover box 4. The lock sleeve can be continuously processed by repeating the above steps.

[0022] The deburring mechanism includes a deburring base plate 7, the top of the deburring base plate 7 is connected to a guide rail mounting plate 2 8, the top of the guide rail mounting plate 2 8 is connected to a cylinder mounting plate 2 11, a deburring cylinder 13 is vertically mounted on the cylinder mounting plate 2 11 through a cylinder mounting plate 1 12, an induction switch 14 is arranged on the deburring cylinder 13, the telescopic end of the deburring cylinder 13 passes through the cylinder mounting plate 2 11 and the cylinder mounting plate 1 12 and is connected to a cylinder connecting plate 15 with a downward opening in a C shape, a rotating cylinder 17 is arranged in the opening of the cylinder connecting plate 15, a speed regulating valve 16 is arranged on the rotating cylinder 17, and the rotating end of the rotating cylinder 17 is connected to a brush 21 through a round brush connecting sleeve 20. Through this structure, the deburring cylinder 13 can realize the up and down displacement of the rotating cylinder 17 and its connecting structure, and the rotating cylinder 17 can drive the brush 21 to rotate.

[0023] With the above structure, the deburring cylinder 13 is solely used to drive the rotating cylinder 17 and its up and down movement. Due to the rotation of the rotating cylinder 17, the position of the brush 21 will be unstable. For this reason, further, the device connects the rotating cylinder mounting plate 18 to the open end of the cylinder connecting plate 15, and the rotating cylinder 17 is mounted on the rotating cylinder mounting plate 18. The rear end of the rotating cylinder mounting plate 18 is connected to the slider mounting vertical plate 19, and the slider mounting vertical plate 19 is connected to the slider 10. The slider 10 is slidably set on the guide rail 9, and the guide rail 9 is vertically installed on the front side of the guide rail mounting plate 28. During the up and down displacement of the brush 21, the slider 10 and the guide rail 9 can guide the displacement direction and maintain the displacement direction. In the rotation processing process, the slider 10 and the guide rail 9 can also play a limiting role, so that the processing process can be more stable and reliable.

[0024] When the brush 21 passes downward through the lock sleeve baffle 22 and extends into the lock sleeve for processing, when it resets upward, the lock sleeve may be lifted up due to being stuck with the brush 21, and cannot be smoothly dropped and collected in the turnover box 4, affecting subsequent processing. To this end, further, the present device is provided with a lock sleeve baffle 22 installed on the front side of the guide rail mounting plate 28 and arranged in an L shape just below the brush 21. By setting the lock sleeve baffle 22, when the lock sleeve is lifted up due to being stuck with the brush 21, the lock sleeve will be blocked by the lock sleeve baffle 22 because it is larger than the brush hole, and cannot move upward with the brush 21. When the brush 21 continues to move upward and exceeds the height of the lock sleeve baffle 22, the lock sleeve will be blocked by the baffle 22 and fall naturally.

[0025] Furthermore, a connecting rib plate 23 is provided at the corner of the lock sleeve baffle 22. The connecting rib plate 23 is provided to strengthen the strength of the lock sleeve baffle 22, making it stable and durable.

Through the above structure, the front and rear cylinders 34 can drive the slider cover 25 and the structure thereon to slide along the guide rail 24; the cylinders symmetrically arranged on the left and right, the right sliding cylinder 40 and the left sliding cylinder 46 can drive the two clamp bases 31 and the lock sleeve clamps 29 thereon to move closer or apart. When the two lock sleeve clamps 29 move closer to a suitable position, they are combined into a special clamp to be added with a lock sleeve, and the lock sleeve can be positioned and not rotated when the lock sleeve is placed in the special clamp; when the two lock sleeve clamps 29 are separated, the lock sleeve naturally falls out. When driving a lock sleeve of a different model, it is only necessary to replace the lock sleeve clamp 29 that is adapted to the lock sleeve, and the clamp base 31 and the lock sleeve clamp 29 are connected by bolts, which is convenient for replacement.

[0027] A buffer mounting seat 33 mounted on the workbench 3 is provided beside the front and rear cylinders 34, and a buffer 32 arranged toward the slider cover 25 is provided on the buffer mounting seat 33. The buffer 32 acts on the side of the slider cover 25 to play a buffering role in the movement process, protecting the functional safety and normal use of the mechanism.

[0028] The slider cover 25 is provided with an L-shaped second slide groove 26 and an L-shaped first slide groove 28 which are arranged in parallel, opposite and spaced apart, and the two clamp bases 31 are slidably arranged between the L-shaped second slide groove 26 and the L-shaped first slide groove 28. The two L-shaped second slide grooves 26 and the L-shaped first slide groove 28 are limited and guided to improve the stability of the two clamp bases 31 during displacement.

[0029] The L-shaped chute 26 is provided with a second limit block 27, and the L-shaped chute 28 is provided with a first limit block 43. The setting of the second limit block 27 and the first limit block 43 ensures that the two locking sleeve clamps 29 can stay at the required center position when they move to the left and right sides and finally merge.

[0030] The left and right parts of the workbench 3 are provided with laser sensors 6 toward the middle; the two front columns of the frame 2 are respectively provided with safety gratings 1.

[0031] The sensor switch 14 on the deburring cylinder 13, the sensor switch 2 35 on the front and rear cylinders 34, the sensor switch 3 39 on the right sliding cylinder 40, and the sensor switch 4 47 on the left sliding cylinder 46 cooperate with each other to achieve control of the cylinders through the existing technology. The sensor switch can be used to quickly and accurately detect the piston position in the cylinder actuator, and then control each cylinder to push or pull the corresponding connection component to move to the corresponding position (such as: processing position, initial position) The present invention utilizes the existing common controller PLC for control.

[0032] The use method and working principle of the present invention: After the equipment is debugged, the initial state is: the front and rear cylinders 34 have driven the displacement slider cover 25 along the guide rail 24 and its upper parts to the special model fixture 29 located between the left and right laser sensors 6, and the right sliding cylinder 40 and the left sliding cylinder 46 have adjusted the special model fixture 29 to be located in the middle, and then through the adjustment of the front and rear cylinders 34, the special model fixture 29 can be driven to move to the position directly below the brush 21.

[0033] The operation starts from the initial state. The lock sleeve to be processed is manually placed on the special model fixture 29. When the two safety gratings 1 sense that there is no obstacle between them, that is, the human hand has left the frame 2 (to ensure the safety of employees), the laser sensor 6 recognizes that the lock sleeve has been placed (if the lock sleeve is not placed, the receiving device of the laser sensor 6 can receive the laser signal emitted from the opposite side; when the lock sleeve is placed, due to the obstruction of the lock sleeve, the laser signal emitted from the opposite side cannot be received, and the recognition is completed at this time), the equipment starts automatically, and the front and rear cylinders 34 act to move the lock sleeve to the specified position (directly below the brush 21), the deburring cylinder 13 moves downward, and the rotating cylinder 17 acts to rotate the brush 21 to the inner hole of the lock sleeve to complete the deburring. The left sliding cylinder 46 and the right sliding cylinder 40 act simultaneously to separate the fixture base 31 and the lock sleeve fixture 29, and the lock sleeve falls from the lock sleeve drop opening 49 into the turnover box 4 to complete one piece of processing. Afterwards, the left sliding cylinder 46 and the right sliding cylinder 40 return to their initial state, and the lock sleeve fixture 29 is combined and pushed out, forming a processing cycle.
