Detailed Implementation

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0041] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] Please refer to Figure 1-3 This utility model provides a dual-head multi-angle finishing processing device, comprising:

[0043] Base 1;

[0044] Rotating device 2, which is mounted on the base 1;

[0045] Material box 9 is fixedly installed on the rotating device 2 and is used to rotate around the first rotating axis under the drive of the rotating device 2; the material box 9 is provided with abrasive material for grinding the workpiece 11.

[0046] The processing assembly has two sets, which are respectively mounted on the base 1; the processing assembly is used to clamp the workpiece 11, drive the workpiece 11 to move, and drive the workpiece 11 to rotate relative to the abrasive.

[0047] The two sets of processing components are symmetrically arranged along the first rotation axis. During processing, the two sets of processing components respectively drive the two workpieces 11 to move into the material box 9 to a position symmetrical along the first rotation axis.

[0048] Specifically, Figure 3 The dashed line indicates the position of the machining component after rotation.

[0049] The feed hopper 9 contains abrasive material. The workpiece 11 is clamped by the processing components and moved into the abrasive material within the feed hopper 9, where the abrasive material and workpiece 11 rub against each other to complete the processing. Because this invention has two sets of processing components, it can process two workpieces 11 simultaneously, thus improving work efficiency.

[0050] To ensure uniform force distribution when the feed box 9 processes multiple workpieces 11 simultaneously, two sets of processing components are symmetrically arranged along the first rotation axis, moving the two workpieces 11 to positions within the feed box 9 that are symmetrical along the first rotation axis.

[0051] Furthermore, the processing component includes:

[0052] A mobile device, which is mounted on the base 1;

[0053] A processing head 3 is rotatably mounted on the moving device for clamping the workpiece 11; the moving device is used to drive the processing head 3 and the workpiece 11 to move.

[0054] A first driving device 12 is fixedly mounted on the moving device, and the drive shaft of the first driving device 12 is fixedly connected to the processing head 3, for driving the processing head 3 and the workpiece 11 to rotate relative to the grinding material, thereby improving the efficiency of grinding.

[0055] In this embodiment, the first driving device 12 is a servo motor.

[0056] Servo motors enable more precise positioning, ensuring accurate rotation, lifting, and tilting. They also enable high-load operation; the spindle servo drive output speed is adjustable from 0 to 150 rpm, and the spindle speed during machining is adjustable from 30 to 60 rpm. This allows them to adapt to high torque and long-term low-speed or ultra-low-speed operation conditions, thereby reducing the failure rate of the spindle servo drive and extending its service life.

[0057] Furthermore, the mobile device includes:

[0058] The first mounting component 4 is rotatably mounted on the base 1, and the axis of rotation of the first mounting component 4 is parallel to the first axis of rotation.

[0059] The second mounting member 5 is slidably mounted on the first mounting member 4 in a direction parallel to the first rotation axis;

[0060] The third mounting component 6 is rotatably mounted on the second mounting component 5 along a first direction; the first direction is perpendicular to the first rotation axis; the processing head 3 is rotatably mounted on the third mounting component 6; and the first driving device 12 is fixedly mounted on the third mounting component 6.

[0061] Specifically, refer to Figure 2 In this embodiment, since the first rotation axis is parallel to the vertical direction, the rotation axis of the first mounting component 4 is also parallel to the vertical direction, and the rotation of the first mounting component 4 is controlled by a motor mounted on the base 1.

[0062] The second mounting component 5 is slidably mounted vertically on the first mounting component 4. The first mounting component 4 is equipped with a servo motor and a lead screw fixedly connected to the drive shaft of the servo motor. The second mounting component 5 has a threaded hole for connecting to the lead screw. When the drive shaft of the servo motor rotates, it drives the second mounting component 5 to move vertically via the lead screw, thereby adjusting the height of the machining head 3 and the workpiece 11 within the grinding material.

[0063] The rotation axis between the second mounting component 5 and the third mounting component 6 is horizontal and is controlled by a servo motor, thereby adjusting the pitch of the machining head 3 and the workpiece 11. During machining, different surfaces of the workpiece 11 can come into contact with the abrasive material to generate friction.

[0064] In some embodiments, since the workpiece 11 rotates under the drive of the first drive device 12, the workpiece 11 and the machining head 3 are also subjected to the reaction force of the abrasive within the abrasive material. If, by chance, the reaction force is too large, it may cause a deviation between the actual position of the machining head 3 and the workpiece 11 and the required position.

[0065] For example, in some cases, the reaction force may cause the first mounting member 4 to rotate unnecessarily; in severe cases, it may cause multiple processing heads 3 to collide with each other, resulting in complete damage to the equipment. To solve the above problems, this utility model also has the following design:

[0066] Further, refer to Figure 4-5 The first mounting component 4 is equipped with a sensor 7; the base 1 is equipped with a first sensor 13 and a second sensor 14, both of which are used to send a signal when facing the sensor 7, so that the controller controls the first mounting component 4 to stop rotating.

[0067] When the sensing element 7 is directly opposite the first sensor 13, the workpiece 11 moves into the grinding material in the material box 9 under the drive of the processing assembly;

[0068] When the sensing element 7 is directly opposite the second sensor 14, the workpiece 11 moves to the outside of the material box 9 under the drive of the processing assembly.

[0069] Specifically, both the first sensor 13 and the second sensor 14 are infrared sensors, and the sensing element 7 is used to reflect infrared light. When the infrared sensor and the sensing element 7 are facing each other, the infrared light emitted by the infrared sensor is reflected by the sensing element 7 and then detected by the infrared sensor. At this time, it indicates that the first mounting member 4 has been rotated to the corresponding position.

[0070] Based on the above structural design, when the processing head 3 and the workpiece 11 are subjected to a large reaction force, the first mounting component 11 will rotate due to the reaction force, causing a significant positional shift in the processing head 3 and the workpiece 11; consequently, the sensing element 7 will no longer be aligned with the sensor. At this time, the sensor will stop emitting a signal, and the controller will immediately control the processing assembly to stop working, avoiding equipment failure.

[0071] Specifically, in case the sensor and sensing element 7 malfunction, the following structure is also designed:

[0072] Furthermore, a limit block 8 is installed on the base 1;

[0073] An abutment 10 is fixedly installed on the first mounting member 4. The abutment 10 is used to abut against the limiting block 8 to prevent the first mounting member 4 from continuing to rotate.

[0074] Furthermore, the abutment 10 is elastic; in this embodiment, materials such as rubber and nylon are used to buffer the collision between the abutment 10 and the limiting block 8. The rubber material can buffer the collision and reduce the kinetic energy of the collision.

[0075] In this embodiment, a mechanical limit is used to prevent the first mounting component 4 from rotating when subjected to a reaction force.

[0076] Furthermore, both the limiting block 8 and the abutting member 10 are two in number;

[0077] When the first mounting member 4 is rotated to the position where the sensing member 7 is facing the first sensor 13, and continues to rotate, one of the abutting members 10 abuts against one of the limiting blocks 8;

[0078] When the first mounting member 4 rotates to the position where the sensing member 7 is facing the second sensor 14, and continues to rotate, the other abutting member 10 abuts against the other limiting block 8.

[0079] Specifically, the installation of two limit blocks 8 and two abutment parts 10 can prevent damage to one set from causing the first mounting part 4 to completely lose its limit, thus further improving safety.

[0080] Furthermore, the rotating device 2 includes:

[0081] A rotating table 15 is rotatably mounted on the base 1; a material box 9 is fixedly mounted on the rotating table 15; the rotating table 15 is used to drive the material box 9 to rotate.

[0082] A protective cover 16 is mounted on the base 1 and is disposed on the outside of the rotating platform 15.

[0083] Specifically, in the event of a mechanical failure during processing, a protective cover 16 can be installed on the outside of the material box 9 to prevent injury to the workers on the outside, thereby further improving safety.

[0084] The above description is merely a preferred embodiment of this utility model and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of this utility model is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this utility model.
