Specifically, the invention provides a sander, which mainly comprises a frame 10, a feeding mechanism 20, a clamping mechanism 30, a polishing mechanism 40 and a trimming mechanism 50. The present invention will be described in detail below with reference to the accompanying drawings.

The frame 10 is the base support structure of the entire sander and provides a stable mounting and work platform for the other various mechanisms. The frame 10 may be welded from steel to ensure its stability and load carrying capacity. The loading mechanism 20 is disposed above the frame 10, and has a main function of automatically or semi-automatically loading the workpiece to be polished into the clamping mechanism 30. The loading mechanism 20 may include an inclined hopper and a feeding device, such as a screw conveyor or vibratory feeder, to ensure that the workpiece is fed uniformly and continuously into the clamping mechanism 30; of course, it is also understood that the loading mechanism 20 may be a robot, or may be a uniform and continuous motion into the clamping mechanism 30.

The clamping mechanism 30 is rotatably arranged on the frame 10 and is positioned on the right side of the feeding mechanism 20. The main function of the clamping mechanism 30 is to clamp the workpiece and turn the machined surface of the workpiece during the grinding process to ensure that all surfaces of the workpiece are uniformly ground. The clamping mechanism 30 comprises a first clamping assembly 32 and a second clamping assembly 33, which are relatively movably arranged therebetween. When the first clamping assembly 32 and the second clamping assembly 33 are brought into close proximity with each other, they clamp the workpiece. The rotation of the clamping mechanism 30 may be driven by a motor or other power source to effect automatic turning of the workpiece.

While the grinding mechanism 40 is another core part of the present invention, which is movably provided on the frame 10 and located at the front side of the clamping mechanism 30. The grinding mechanism 40 includes a rotatable grinding member 421 such as a grinding wheel or sanding belt.

In conclusion, the polishing machine provided by the invention can realize the operations of automatic feeding, clamping, polishing, trimming and the like of workpieces through the cooperative work of the mechanisms, and the working efficiency and the processing quality are greatly improved. Meanwhile, as all the mechanisms are arranged on the frame 10, the whole sander has compact structure and small occupied area, and is very suitable for being used in a limited space. It can also be appreciated that the sander according to embodiments of the present invention has at least the following beneficial effects: the clamping mechanism 30 is rotatably disposed on the frame 10, so as to drive the clamping positions of the first clamping assembly 32 and the second clamping assembly 33 to move, thereby changing the overturning of the processing surface of the workpiece relative to the polishing mechanism 40, so that the polishing mechanism 40 polishes and processes on a plurality of processing surfaces of the workpiece, and further meets the processing requirements of a plurality of processing surfaces of the workpiece.

Referring to fig. 3 to 5, in some embodiments of the present invention, the clamping mechanism 30 further includes a base 31, the base 31 being rotatably disposed on the frame 10 by a rotary table, the first clamping assembly 32 and the second clamping assembly 33 being disposed on opposite sides of the base 31; the first clamping assembly 32 includes a first driving member 321 and a driving shaft 322. The first driving piece 321 is disposed in the base 31; one end of the driving shaft 322 is arranged at the output end of the first driving piece 321, the first driving piece 321 drives the driving shaft 322 to rotate, the other end of the driving shaft 322 abuts against the outer surface of the workpiece, and the driving shaft 322 can drive the workpiece to rotate. The second clamping assembly 33 includes a second driving member 331 and a rotatable driven shaft 332, the second driving member 331 being disposed in the base 31; one end of the driven shaft 332 is disposed on the output end of the second driving member 331, and the second driving member 331 drives the other end of the driven shaft 332 against the outer surface of the workpiece.

In a further embodiment, the clamping mechanism 30 comprises a base 31 in addition to the first clamping assembly 32 and the second clamping assembly 33. The base 31 is rotatably arranged on the frame 10 through the rotary table, so that the whole clamping mechanism 30 can perform rotary motion on the frame 10, the workpiece can be turned over and polished conveniently, and the flexibility and the working efficiency of the equipment are improved. The base 31 serves as a base member of the clamping mechanism 30, firmly supporting the first clamping assembly 32 and the second clamping assembly 33. The two assemblies are skillfully disposed on opposite left and right sides of the base 31 to facilitate clamping and rotation of the workpiece.

The first clamping assembly 32 is mainly composed of a first driving member 321 and a driving shaft 322. The first driver 321 is disposed in the base 31 to power the entire assembly. One end of the driving shaft 322 is connected to an output end of the first driving member 321, and when the first driving member 321 is started, it drives the driving shaft 322 to rotate. The other end of the driving shaft 322 is used for propping against the outer surface of the workpiece, and the workpiece is driven to rotate through rotation, so that the stability and uniformity of the workpiece in the polishing process are ensured. The second clamping assembly 33 is similar in structure to the first clamping assembly 32 and consists of a second driving member 331 and a driven shaft 332. The second driving member 331 is also provided in the base 31 to provide the driven shaft 332 with power to slide in the base 31. One end of the driven shaft 332 is connected to the output end of the second driving member 331, and the other end is used to abut against the outer surface of the workpiece. When the second driver 331 is activated, it drives the driven shaft 332 to slide leftward, thereby assisting the driving shaft 322 to clamp the workpiece together. When the driving shaft 322 drives the workpiece to rotate, the rotatable driven shaft 332 can cooperate with the driving shaft 322 to clamp and rotate the workpiece, so that the polishing mechanism 40 is convenient to uniformly polish the workpiece. Furthermore, the first clamping assembly 32 and the second clamping assembly 33 provide a larger polishing area of the polishing mechanism 40 when the base 31 rotates.

The double-shaft clamping design not only improves the stability of the workpiece, but also ensures the polishing uniformity and quality. Meanwhile, by adjusting the rotation speeds and directions of the base 31, the first driving piece 321 and the second driving piece 331, complex rotation movement of the workpiece can be realized, so as to meet different polishing requirements.

Referring to fig. 3 to 5, in some embodiments of the present invention, an output end of the second driving member 331 is connected to an end of the driven shaft 332 through a link 34, the link 34 is disposed in the base 31 and between the second driving member 331 and the driven shaft 332, a middle portion of the link 34 is rotatably connected to the base 31, a first end of the link 34 abuts against the output end of the second driving member 331, and a second end of the link 34 is hinged to an end of the driven shaft 332.

Further, in the clamping mechanism 30, the output end of the second driving member 331 is not directly connected to the driven shaft 332, but is connected through a connecting rod 34. The link 34 is disposed in the base 31 between the second driving member 331 and the driven shaft 332. The middle part of the connecting rod 34 is rotatably connected with the base 31 through a bearing or other rotatable connection modes, so that the connecting rod 34 can freely rotate within a certain range. The first end of the link 34 abuts against the output end of the second driver 331. When the second driving member 331 is activated, the power of the output end thereof is transmitted to the first end of the link 34, thereby driving the link 34 to rotate about the hinge rotation center with the base 31, i.e., the link 34 can rotate in a horizontal plane. Due to the rotatable connection of the link 34 with the base 31, such rotation can be performed smoothly and efficiently. The second end of the connecting rod 34 is hinged to one end of the driven shaft 332, and when the first end of the connecting rod 34 rotates to the right under the driving force of the second driving member 331, the second end of the connecting rod drives the driven shaft 332 to rotate to the left, so that the driven shaft 332 in the base 31 is driven to slide to the left, and finally the driving shaft 322 is matched to clamp and fix a workpiece. The lever hinge manner of the connecting rod 34 allows the driven shaft 332 to flexibly rotate within a certain range under the driving of the connecting rod 34, so that the shape and polishing requirements of a workpiece can be better met. By this connection of the connecting rod 34, the power of the second driving member 331 can be more smoothly and flexibly transferred to the driven shaft 332, thereby achieving more stable and efficient workpiece clamping and rotation. Meanwhile, the durability and the reliability of the equipment are improved, and the maintenance cost is reduced.

Referring to fig. 6-7, in some embodiments of the present invention, the clamping mechanism 30 further includes an adjustment assembly 35, the adjustment assembly 35 being disposed on the base 31 and located at a first end of the link 34, the adjustment assembly 35 being configured to adjust one end of the link 34 to adjust the travel of the other end of the link 34, the adjustment assembly 35 including an adjustment member 351, an adjustment bracket 352, and a connection member 353. The adjusting member 351 is provided on the base 31; the adjusting frame 352 is slidably disposed on the output end of the second driving part 331, the adjusting frame 352 is provided with a movable groove 3521, and the first end of the connecting rod 34 is movably disposed in the movable groove 3521; the connecting member 353 is movably inserted through the adjusting frame 352, one end of the connecting member 353 is connected to the adjusting member 351, and the other end of the connecting member 353 is inserted into the movable slot 3521 and abuts against one side of the first end of the connecting rod 34. In the clamping mechanism 30, an adjusting assembly 35 is added in particular in order to more precisely control the movement stroke of the connecting rod 34, thereby precisely controlling the rotation angle and clamping force of the driven shaft 332. An adjustment assembly 35 is provided on the base 31 at a first end of the link 34 for effective adjustment of the link 34.

Specifically, the adjustment assembly 35 is comprised of three parts, mainly an adjustment member 351, an adjustment bracket 352, and a connection member 353. The adjustment member 351 is firmly provided on the base 31 as a fixing point of the entire adjustment assembly 35. The adjusting frame 352 is slidably disposed on the output end of the second driving member 331, and the driving force of the second driving member 331 drives the adjusting frame 352 to move, thereby controlling the movement of the first end of the connecting rod 34 in the adjusting frame 352. The adjustment bracket 352 is provided with a movable groove 3521, and the first end of the link 34 is movably disposed in the movable groove 3521. This design ensures that the link 34 has sufficient degrees of freedom during movement while being effectively constrained within a predetermined range. And the connecting piece 353 is a key component of the rotation stroke of the adjusting link 34 in the adjusting assembly 35, and the connecting piece 353 is movably penetrated on the adjusting bracket 352. One end of the connecting member 353 is connected to the adjusting member 351, and the other end is disposed in the movable slot 3521 and abuts against one side of the first end of the connecting rod 34. By adjusting the position of the link 353 by the adjusting member 351, the position of the first end of the link 34 can be precisely controlled, thereby adjusting the stroke of the other end of the link 34.

In actual operation, when the stroke of the link 34 needs to be adjusted, the position of the first end of the link 34 in the movable slot 3521 can be changed by only adjusting the position of the connecting member 353 on the adjusting bracket 352. This design not only makes the stroke adjustment of the link 34 simple and convenient, but also ensures the accuracy and stability of the adjustment. Through the design of the adjusting component 35, the clamping mechanism 30 of the sanding machine can control the clamping force and the clamping stroke of the workpiece more accurately, so that the precision and the efficiency of sanding are improved. Meanwhile, the design also enhances the flexibility and adaptability of the equipment, so that the equipment can better meet the processing requirements of different workpieces and the clamping of the workpieces with different sizes.

It should be noted that, the connecting member 353 may be a screw, and the adjusting member 351 is a knob with graduations, and the specific position of the left end of the connecting member 353 can be controlled by rotating the adjusting member 351, so as to control the stroke of the first end of the connecting rod 34. Of course, the connecting member 353 may be a connecting rod, and the position of the left end thereof in the movable groove 3521 of the adjusting bracket 352 may be adjusted by the adjusting member 351.

Referring to fig. 4, 5 and 8, in some embodiments of the present invention, the clamping mechanism 30 further includes a positioning assembly 36, the positioning assembly 36 is disposed in the base 31 and located below the first clamping assembly 32 and the second clamping assembly 33, the positioning assembly 36 includes a movable positioning seat 361, the positioning seat 361 is located below between the first clamping assembly 32 and the second clamping assembly 33, and the positioning seat 361 is used for supporting and positioning the workpiece. In the clamping mechanism 30, a positioning assembly 36 is added to ensure stability and accuracy of the workpiece during processing. A positioning assembly 36 is disposed in the base 31 below the first clamping assembly 32 and the second clamping assembly 33 to provide firm support and accurate positioning of the workpiece.

Specifically, the positioning assembly 36 is mainly composed of a movable positioning seat 361. The positioning seat 361 is disposed below the first clamping assembly 32 and the second clamping assembly 33 to form a stable supporting platform. When a workpiece is placed on the positioning seat 361, the positioning seat 361 can effectively support the workpiece and ensure that the workpiece is in a correct position, and provides accurate positioning for subsequent processing operations. The design of the positioning seat 361 takes into account the shape, weight and tooling requirements of the workpiece to ensure that it provides adequate support and stability. Meanwhile, the mobility of the positioning seat 361 also enables the positioning seat to adapt to workpieces with different sizes and shapes, so that the flexibility and the universality of the equipment are enhanced. When the workpiece is placed on the positioning seat 361, the first clamping assembly 32 and the second clamping assembly 33 respectively clamp the workpiece from two sides. Because of the stable support and accurate positioning of the positioning seat 361, the workpiece can be kept stable in the machining process, so that the machining precision and efficiency are improved. Through the design of the positioning assembly 36, the clamping mechanism 30 of the sander can provide more stable support and accurate positioning when clamping the workpiece, thereby ensuring the processing quality and precision of the workpiece, not only improving the overall performance of the equipment, but also making the operation simpler and safer.

Further, referring to fig. 4-5 and 8, in some embodiments of the present invention, the positioning assembly 36 further includes a mount 362, a first drive assembly 363, and a second drive assembly 364. The mount 362 is mounted in the base 31; the first driving assembly 363 is disposed on the mounting base 362, and an output direction of an output end of the first driving assembly 363 extends along the first direction; the second driving assembly 364 is disposed on an output end of the first driving assembly 363, an output direction of the output end of the second driving assembly 364 extends along the second direction, and the positioning seat 361 is disposed on the output end of the second driving assembly 364. The positioning assembly 36 provides flexible adjustment functions to accommodate different workpiece requirements in order to more precisely control and adjust the position of the positioning seat 361, ensure stable positioning of the workpiece, and the positioning assembly 36 further includes a mounting seat 362, a first drive assembly 363, and a second drive assembly 364.

Specifically, the mounting blocks 362 are securely mounted within the base 31, providing a solid support foundation for the entire positioning assembly 36, while facilitating removal from the base 31. The first driving assembly 363 is disposed on the mounting base 362, and the output direction of the output end thereof extends along the first direction, i.e. the up-down direction as shown. This design allows for precise movement of the positioning socket 361 in the first direction to accommodate workpieces of different heights. And the second driving unit 364 is disposed at an output end of the first driving unit 363, and an output direction of the output end thereof extends in a second direction, i.e., a front-rear direction as illustrated, which is perpendicular to the first direction. The positioning seat 361 is finally provided on the output end of the second driving assembly 364, so that it can be precisely moved in the second direction by the driving of the second driving assembly 364.

Through the design of the double driving components, the positioning seat 361 can independently move in the front-back direction and the up-down direction, and extremely high positioning precision and flexibility are provided for the workpiece. In practice, an operator can precisely adjust the position of the positioning seat 361 by controlling the first drive assembly 363 and the second drive assembly 364 according to the size and shape of the workpiece, thereby ensuring the stability and accuracy of the workpiece during the machining process. In addition, the positioning seat 361 can rapidly and accurately respond to the change of the processing requirement, and the production efficiency is greatly improved. Meanwhile, due to the flexibility and adjustability of the positioning seat 361, the sanding machine can process workpieces of various types and sizes, and the application range of the sanding machine is further widened.

The polishing assembly 42 is slidably disposed on the sliding table 41 along the front-rear direction, and can be far away from or near to the workpiece along the front-rear direction, so that not only is the position of the polishing member 421 convenient to adjust, but also the polishing member 421 can adapt to workpieces of different sizes and shapes.

The grinding assembly 42 comprises a third drive member 422 and a grinding member 421, wherein the grinding member 421 is mounted directly on the output end of the third drive member 422. The third driving member 422 may be a motor or a servo motor to provide rotational power to the grinding member 421. When the third driving member 422 is activated, it drives the grinding member 421 to rotate at a high speed through the output shaft. The rotary motion is important to remove rough parts of the surface of the workpiece, and the workpiece can be effectively frosted, so that the surface of the workpiece is smoother and finer. An operator can adjust the position of the sliding table 41 and the rotation speed of the polishing member 421 through the control system according to the material, shape and processing requirements of the workpiece, so as to achieve the optimal polishing effect. In addition, the cooperative work of the sliding table 41 and the polishing assembly 42 also greatly improves the production efficiency, reduces the operation difficulty, and enables the polishing treatment to be more efficient, accurate and controllable.
