Description

Technical Field

[0001] This utility model relates to the field of casting production technology, specifically to a polishing device for casting production. Background Technology

[0002] Casting is one of the fundamental processes in modern machinery manufacturing. As a metal heat treatment process, casting has gradually matured in my country. Casting machinery is a type of machinery that uses this technology to melt metal into a liquid that meets certain requirements and pour it into a mold. After cooling and solidification, and cleaning, castings with predetermined shapes, sizes, and properties are obtained. After casting is completed, polishing is required. Polishing refers to the processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece in order to obtain a bright and smooth surface. It is a finishing process that uses polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece.

[0003] Traditional polishing equipment used in casting production and processing is not convenient to adjust the height of the polishing wheel according to the thickness of the casting, which can easily lead to unevenness on the surface of the casting after polishing. Secondly, the polishing mechanism cannot be angled, which limits its ability to adapt to the polishing needs of workpieces with different shapes and angles, reducing work efficiency and polishing quality. Utility Model Content

A second transmission rod is rotatably installed inside each of the two sets of ear plates, and a second bevel gear is fixedly installed at both ends of each of the two sets of second transmission rods. The two sets of second bevel gears mesh with the first bevel gear and the third bevel gear, respectively.

[0009] Preferably, two sets of first track blocks are fixedly installed on the inner side of the two sets of fourth fixed plates, and the two sets of first track blocks are welded to the top of the mounting plate. A third slider is slidably installed inside the two sets of first track blocks, and the two sets of third sliders are threadedly connected to the outer surface of the third lead screw. A second connecting rod is rotatably installed on the outer surface of the two sets of third sliders. The other end of the two sets of second connecting rods is rotatably installed on the outer surface of the fourth slider. The two sets of fourth sliders are slidably connected to the inside of the second track blocks, and the two sets of second track blocks are fixedly installed on the top of the movable plate. A motor base is fixedly installed at the bottom of the movable plate, and a third motor is fixedly installed inside the motor base. A polishing disc is fixedly installed through the bottom of the motor base at the output end of the third motor.

[0010] Preferably, a third link is rotatably mounted inside the two sets of second links, and the other end of the two sets of third links is rotatably mounted at the bottom end of the mounting plate.

[0011] Preferably, the clamping mechanism includes a first fixed plate, with a first lead screw rotatably mounted inside each of the two sets of first fixed plates, and a first guide rod provided inside each of the two sets of first fixed plates. A first motor is provided on one side of one set of first fixed plates, and the first motor is fixedly mounted on the top of the base plate. The output end of the first motor is fixedly mounted on one end of one set of first lead screws. The two sets of first lead screws are connected to a synchronous belt drive via a rotating wheel. Two sets of first sliders are threadedly connected to the outer surface of each set of first lead screws, and the two sets of first sliders are slidably connected to the outer surface of the first guide rod. The top and bottom ends of the two sets of first sliders are movably connected to the clamping member via a first connecting rod.

[0012] Preferably, the outer surfaces of the two sets of first lead screws have two sets of threads with opposite directions.

[0013] Preferably, the moving mechanism includes a second motor, and a second lead screw is fixedly installed on one side of the output end of the second motor through the connecting plate. Two sets of second fixing plates are fixedly installed on the front top of the base plate. The second lead screw is rotatably installed inside one set of second fixing plates, and a second guide rod is fixedly installed inside the other set of second lead screws.

[0014] Preferably, two sets of second sliders are fixedly installed on the top of the mounting plate, one set of the second sliders being threadedly connected to the outer surface of the second lead screw, and the other set of the second sliders being slidably connected to the outer surface of the second guide rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] First, the flexible adjustment of the polishing wheel height is achieved through the linkage mechanism of the dual-head motor with the first transmission rod, the first bevel gear, the third lead screw, and the third bevel gear. Specifically, when the dual-head motor drives the first transmission rod to rotate, the first bevel gear rotates accordingly, and through its meshing with the second bevel gear, it drives the third bevel gear and the third lead screw to rotate. Since the third lead screw is threadedly connected to the third slider, the rotation of the lead screw is converted into linear motion of the third slider within the first track block. This motion, through the transmission of the second connecting rod and the fourth slider, drives the movable plate and polishing disc to move up and down. This design effectively solves the problem that traditional polishing devices are not convenient for adjusting the polishing wheel height according to the thickness of the casting, ensuring the uniformity of the casting surface after polishing and improving the polishing quality. Second, when the dual-head motor drives the first transmission rod and the first bevel gear to rotate, the meshing second bevel gear not only transmits power to the third bevel gear... The height of the polishing wheel is adjusted, and the rotational motion is transmitted to another set of second bevel gears meshing with the third bevel gear via the second transmission rod. This allows the polishing mechanism to adjust the angle while maintaining the height adjustment function. By adjusting the angle of the polishing mechanism, it can better adapt to the polishing needs of workpieces with different shapes and angles, thereby improving work efficiency and polishing quality. Finally, the third connecting rod serves as a stable support and auxiliary transmission structure, further enhancing the stability and reliability of the polishing mechanism's angle adjustment. The two ends of the third connecting rod are respectively rotatably installed at the bottom of the mounting plate and inside the second connecting rod, forming a stable triangular support structure. This not only helps to disperse and adjust the forces and torques generated during the angle adjustment process, but also ensures the smooth operation of the polishing mechanism during the angle adjustment process, avoiding vibration or displacement caused by angle changes, and further improving the stability and quality of the polishing operation.

[0028] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0029] Reference Figure 4As shown, the device includes a base plate 1, a clamping mechanism 2 at the top of the base plate 1, a connecting plate 3 fixedly mounted at the rear bottom of the base plate 1, a moving mechanism 4 at the top front of the connecting plate 3, a mounting plate 5 at the bottom of the moving mechanism 4, and a polishing mechanism 6 at the top of the mounting plate 5. The polishing mechanism 6 includes a dual-head motor 601, which is fixedly mounted at the top of the mounting plate 5. Two sets of third fixing plates 604 are fixedly mounted on the left and right top ends of the mounting plate 5. Two sets of first transmission rods 602 are welded to the output ends on both sides of the dual-head motor 601. One end of each mounting plate 5 is fixedly installed with a first bevel gear 603 through the third fixing plate 604. Two sets of fourth fixing plates 608 are fixedly installed on the left and right bottom ends of the mounting plate 5, and a third lead screw 609 is rotatably installed inside each of the two sets of fourth fixing plates 608. One end of each of the two sets of third lead screws 609 is fixedly installed with a third bevel gear 610 through the fourth fixing plate 608. Two sets of ear plates 605 are fixedly installed on the left and right sides of the mounting plate 5, and a second transmission rod 606 is rotatably installed inside each of the two sets of ear plates 605. Both ends of each of the two sets of second transmission rods 606 are fixedly installed with a second bevel gear 610. 07, and the two sets of second bevel gears 607 mesh with the first bevel gear 603 and the third bevel gear 610 respectively. Two sets of first track blocks 611 are fixedly installed on the inner sides of the two sets of fourth fixing plates 608, and both sets of first track blocks 611 are welded to the top of the mounting plate 5. A third slider 612 is slidably installed inside each set of first track blocks 611, and both sets of third sliders 612 are threadedly connected to the outer surface of the third lead screw 609. A second connecting rod 613 is rotatably installed on the outer surface of each set of third sliders 612, and a third connecting rod 613 is rotatably installed inside each set of second connecting rods 613. The other ends of the two sets of third connecting rods 614 are rotatably mounted on the bottom end of the mounting plate 5. The other ends of the two sets of second connecting rods 613 are rotatably mounted on the outer surface of the fourth slider 616. The two sets of fourth sliders 616 are connected to the inside of the second track block 615. The two sets of second track blocks 615 are fixedly mounted on the top end of the movable plate 617. The bottom end of the movable plate 617 is fixedly mounted with a motor base 618. The inside of the motor base 618 is fixedly mounted with a third motor 619. The output end of the third motor 619 passes through the bottom end of the motor base 618 and is fixedly mounted with a polishing disc 620.

[0030] In this design, the power is transmitted from the first transmission rod 602 to the first bevel gear 603 via the drive of the dual-head motor 601. Then, through the meshing action of the second bevel gear 607, the power is distributed and converted in the horizontal and vertical directions. The sliding engagement of the first track block 611 and the third slider 612, as well as the linkage mechanism of the second connecting rod 613, the third connecting rod 614 and the fourth slider 616, adjust the position and angle of the polishing disc 620 to achieve fine polishing. The stable connection between the movable plate 617 and the motor base 618 provides a stable working platform for the third motor 619 and the polishing disc 620, ensuring the smooth progress of the polishing process.

[0031] Reference Figure 1-2 As shown, the clamping mechanism 2 includes a first fixed plate 201. A first lead screw 203 is rotatably installed inside both sets of first fixed plates 201. A first guide rod 204 is provided inside both sets of first fixed plates 201. A first motor 202 is provided on one side of one set of first fixed plates 201, and the first motor 202 is fixedly installed on the top of the base plate 1. The output end of the first motor 202 is fixedly installed on one end of one set of first lead screws 203. The two sets of first lead screws 203 are connected to the synchronous belt 208 through a rotating wheel. Two sets of first sliders 205 are threadedly connected to the outer surface of the two sets of first lead screws 203. The two sets of first lead screws 203 have two sets of threads with opposite directions on their outer surfaces. The two sets of first sliders 205 are slidably connected to the outer surface of the first guide rod 204. The top and bottom ends of the two sets of first sliders 205 are movably connected to the clamping member 207 through a first connecting rod 206.

[0032] In this scheme, the first motor 202 drives the first lead screw 203 to rotate, causing the thread on the outer surface of the first lead screw 203 to move the first slider 205, realizing the opposite or opposite movement of the two sets of clamping parts 207. This not only has a simple structure and is easy to control, but also can be flexibly adjusted according to the size of different workpieces, ensuring the stability and reliability of clamping. At the same time, the introduction of the first guide rod 204 provides guidance and support for the sliding of the first slider 205, effectively preventing lateral displacement caused by the rotation of the lead screw, and further improving the accuracy and stability of the clamping mechanism 2.

[0033] Reference Figure 3As shown, the moving mechanism 4 includes a second motor 401. The output end of the second motor 401 is fixedly installed with a second lead screw 402 through one side of the connecting plate 3. Two sets of second fixing plates 405 are fixedly installed on the front top of the base plate 1. The second lead screw 402 is rotatably installed inside one set of second fixing plates 405. A second guide rod 403 is fixedly installed inside the other set of second lead screws 402. Two sets of second sliders 404 are fixedly installed on the top of the mounting plate 5. One set of second sliders 404 is threaded to the outer surface of the second lead screw 402, and the other set of second sliders 404 is slidably connected to the outer surface of the second guide rod 403.

[0034] In this scheme, by activating the output end of the second motor 401, the second slider 404 moves on the outer surface of the second lead screw 402, realizing the movement of the mounting plate 5 and all its components. This allows the entire polishing mechanism 6 to adjust its height, facilitating processing of different positions on the workpiece. The sliding cooperation between the second guide rod 403 and another set of second sliders 404 plays a role in balancing and stabilizing, ensuring the smoothness and accuracy of the movement process.

[0035] The working principle of this utility model is as follows: When the first motor 202 starts, it drives one set of first lead screws 203 to rotate through the output end. Since the two sets of first lead screws 203 are connected to the synchronous belt 208 through a pulley, the two sets of lead screws will rotate synchronously and at the same angular velocity, but their threads are opposite. As the first lead screw 203 rotates, the two sets of first sliders 205 will move in opposite directions along the outer surface of the lead screw. When the first slider 205 moves, it will drive the clamping member 207 to move closer or further away, thereby realizing the clamping or release of the workpiece. When the second slider 205 moves... After the motor 401 starts, its output end drives the second lead screw 402 to rotate. The second lead screw 402 is rotatably mounted inside the second fixed plate 405 at the top front side of the base plate 1. A second guide rod 403 is fixedly mounted inside another set of second lead screws 402 to maintain stability in the direction of movement. Of the two sets of second sliders 404 at the top of the mounting plate 5, one set is threaded to the outer surface of the second lead screw 402 and moves with the rotation of the lead screw; the other set is slidably connected to the outer surface of the second guide rod 403 to ensure smooth movement. The rotation of the second slider 404, which is threadedly connected to it, drives the entire mounting plate 5 to move along the screw axis, thereby realizing the overall movement of the polishing mechanism 6. After the dual-head motor 601 is started, its output ends on both sides drive the two sets of first transmission rods 602 to rotate. The first transmission rods 602 drive the first bevel gear 603 to rotate. The first bevel gear 603 meshes with the second bevel gear 607, thereby driving the second transmission rod 606 and the second bevel gear 607 to rotate. At the same time, the second bevel gear 607 also meshes with the third bevel gear 610, driving the two sets of third screws 609 to rotate. The rotation of the three lead screw 609 causes the third slider 612 to move threadedly on its outer surface. The third slider 612, through the transmission of the second connecting rod 613 and the third connecting rod 614, pushes the fourth slider 616 to slide within the second track block 615, thereby driving the movable plate 617 to move up and down. After the third motor 619, which is fixedly installed in the motor base 618 at the bottom of the movable plate 617, is started, its output end drives the polishing disc 620 to rotate, performing polishing operations on the workpiece. As the movable plate 617 moves up and down, the polishing disc 620 can perform uniform polishing treatment on the surface of the workpiece.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
