Description

Technical Field

[0001] The present application relates to the technical field of hardware processing, and in particular to a polishing auxiliary device for cylindrical castings. Background Art

[0002] Metal castings refer to workpieces made of pure metal or alloy obtained by casting. Burrs are inevitable on the surface of metal castings during the production process, and the formed metal castings need to be polished.

[0003] Cylindrical castings are a common type of metal castings, which generally require polishing of the ends or outer walls. The common polishing method is to clamp and fix the cylindrical castings with a clamping and fixing mechanism, and then cooperate with a rotary drive mechanism to drive the casting to rotate. The grinding mechanism acts on the end of the casting to grind and polish the burrs. The grinding process can be achieved by manually driving the grinding mechanism to move, or by using an automatic grinding mechanism. In this process, most of the time, manual loading and unloading is required, that is, the staff removes a workpiece after completing the grinding, and then places the next workpiece to be polished on the fixing mechanism for fixing. This process still has room for improvement, which can further improve efficiency and reduce manual operation. Utility Model Content

[0004] The purpose of the present application is to provide a cylindrical casting polishing auxiliary device to solve at least one of the above-mentioned technical problems.

[0005] In order to solve the above technical problems, the present application provides a cylindrical casting polishing auxiliary device, including a working base;

[0006] A loading assembly and a rotating assembly for driving the cylindrical workpiece to rotate are provided on the work base;

[0007] The loading assembly comprises a first loading platform, a second loading platform and a third loading platform, all of which are arranged in an inclined manner, the second loading platform is located between the first loading platform and the third loading platform, and the first loading platform is arranged close to the transfer assembly; a first lifting driving member is arranged on the working base below the first loading platform, and the table surface of the first loading platform is higher than the third loading platform; the second loading platform is suitable for accommodating a cylindrical workpiece;

[0008] Wherein, the second loading platform has an ascending state and a descending state under the drive of the first lifting drive member. When in the ascending state, the table top extension surface of the second loading platform is higher than or overlaps with the table top extension surface of the first loading platform. When in the descending state, the table top extension surface of the second loading platform is lower than or overlaps with the table top extension surface of the third loading platform.

[0009] In the above implementation process, the staff puts multiple workpieces onto the third loading platform, and the third loading platform is inclined. Under the action of gravity, the workpieces roll toward the second loading platform, and the workpiece at the front end is located on the second loading platform. At this time, the first lifting drive can drive the workpiece located thereon to rise and switch to the rising state. Since the second loading platform is also inclined, after the second loading platform rises, under the action of gravity, the workpiece continues to move forward to the first loading platform, and then further slides from the third loading platform into the transfer assembly. The transfer assembly can drive the workpiece to rotate, and then cooperate with the subsequent polishing of the cylindrical casting. After the second loading platform guides the workpiece to the first loading platform; in this solution, multiple workpieces can be put in at one time, and there is no need to manually load them one by one, which effectively saves manpower. At the same time, it can also connect with the upstream unloading mechanism, providing a strong premise for realizing automated polishing.

[0010] Preferably, the material transfer assembly includes a first fixed frame, a second fixed frame, a driving roller, a driven roller and a rotating driving member;

[0011] The first fixed frame is mounted on the working base, the driving roller is rotatably mounted on the first fixed frame, and the rotating driving member is fixed on the first fixed frame and is suitable for driving the driving roller to rotate;

[0012] The second fixed frame is arranged on the working base, and the driven roller is rotatably arranged on the second fixed frame;

[0013] The axial directions of the driving roller and the driven roller are parallel to each other, and the horizontal position of the highest point thereof is lower than the table surface of the first loading table, and the cylindrical workpiece is suitable for falling between the driving roller and the driven roller;

[0014] In the above implementation process, the workpiece further rolls from the first loading platform to between the driving roller and the driven roller. The driving roller rotates under the action of the rotating drive member, thereby driving the workpiece to rotate. In this process, the driven roller will also rotate to avoid excessive relative friction between the workpiece and the driven roller, thereby playing a certain protective role for the workpiece.

[0015] Preferably, an auxiliary wheel assembly is further included; the auxiliary wheel assembly includes a first bracket, a second lifting drive member, a third fixed bracket and an auxiliary wheel; the auxiliary wheel is rotatably arranged on the third fixed bracket, the third fixed bracket is connected to the driving end of the second lifting drive member, the second lifting drive member is suitable for driving the auxiliary wheel to rise and fall to abut against the outer wall of the cylindrical workpiece, the first bracket is arranged on the working base, and the second lifting drive member is fixedly arranged on the first bracket;

[0016] In the above implementation process, after the workpiece falls between the driving roller and the driven roller, the second lifting drive member drives the third fixed frame to move downward, so that the auxiliary wheel abuts against the workpiece, and then cooperates with the driving roller and the driven roller to realize the positioning of the workpiece. After further adding the auxiliary wheel, this scheme effectively improves the limiting stability of the workpiece, thereby improving the stability of the subsequent polishing process.

[0017] Preferably, a baffle is provided below one end of the second loading platform close to the third loading platform;

[0018] When the second loading platform is in the ascending state, the ascending is blocked at an end of the third loading platform close to the second loading platform;

[0019] In the above implementation process, when the second loading platform rises, the baffle connected to it will also rise. In this way, after the second loading platform switches to the rising state, the remaining workpieces are blocked by the baffle and will not move further forward. After the second loading platform moves down, the baffle follows it to move down. When the second loading platform enters the descending state, the remaining workpieces will move further forward, moving forward one workpiece at a time, thereby realizing automatic material replenishment.

[0020] Preferably, a first linear drive member is provided on the working base;

[0021] The second fixed frame is arranged at the driving end of the linear driving member, and the linear driving member drives the driven roller to approach or move away from the driving roller;

[0022] In the above implementation process, the first driving member can drive the second fixed frame to move, thereby driving the distance between the driving roller and the driven roller to change. For example, when encountering a cylindrical workpiece with a larger diameter, the distance between the driving roller and the driven roller can be increased. When encountering a workpiece with a smaller diameter, the distance between the driving roller and the driven roller can be reduced. The auxiliary device provided in this application can be adapted to the production and processing of more workpieces, thereby improving the compatibility of the device.

[0023] Preferably, a material discharge port is provided on the working base below the driving roller and the driven roller;

[0024] A material discharge channel communicating with the material discharge port is provided in the working base;

[0025] In the above implementation process, after the workpiece is processed, the first linear drive member drives the second fixed frame to move to drive the driven roller away from the driving roller. When the two are away from each other to a certain extent, the workpiece will fall from between the driving roller and the driven roller. The fallen workpiece enters the feeding channel from the feeding port, and is finally guided to the designated position from the feeding channel for centralized collection. There is no need to manually remove the processed workpiece, which further reduces manpower input, improves the degree of production automation, and effectively improves work efficiency.

[0026] Preferably, the first loading platform, the second loading platform and the third loading platform all include a substrate and a limiting plate arranged on the substrate;

[0027] The limit plates are provided with two and are arranged opposite to each other;

[0028] In the above implementation process, the substrate provides a supporting surface for the workpiece, and the two limiting plates located on the substrate can limit the workpiece, thereby arranging multiple workpieces more neatly and orderly, thereby realizing stable automatic material replenishment.

[0029] Preferably, waist-shaped holes are provided on the substrate along its width direction;

[0030] It also includes a fixing member suitable for penetrating the waist-shaped hole and fixing the limiting plate on the base plate;

[0031] In the above implementation process, the staff can loosen the fixing parts to allow the base plate to be flexibly adjusted along the waist-shaped hole, and then tighten the fixing parts after adjusting to the appropriate position to fix the limit plate and the base plate; this solution can adjust the distance between the two limit plates by adjusting the position of the limit plate, thereby adapting to cylindrical workpieces of different lengths and improving the applicability of the device.

[0032] Compared with the prior art, the beneficial effect of the present application is that multiple workpieces can be put in at one time in the present solution without the need for manual loading one by one. Through the cooperation of the inclined first loading table, the second loading table and the third loading table, automatic material replenishment can be achieved, effectively saving manpower. At the same time, it can also connect with the upstream unloading mechanism, providing a strong premise for realizing automated polishing. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to further understand the content, features and effects of the utility model of the present application, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0042] Example

[0043] A cylindrical casting is a common type of metal casting, which generally needs to be polished at the end or the outer wall. A common polishing method is to clamp and fix the cylindrical casting with a clamping and fixing mechanism, and then cooperate with a rotary drive mechanism to drive the cast casting to rotate. The grinding mechanism acts on the end of the casting to grind and polish the burrs. The grinding process can be achieved by manually driving the grinding mechanism to move, or by using an automatic grinding mechanism. In this process, most of the materials need to be loaded and unloaded manually one by one, that is, the staff removes a workpiece after completing the grinding, and then puts the next workpiece to be polished on the fixing mechanism for fixing. This process still has room for improvement, which can further improve efficiency and reduce manual operation. In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0044] For details, see Figure 1-3 ,This embodiment provides a cylindrical casting polishing auxiliary device, including a working base;

[0045] Specifically, a loading assembly and a rotating assembly for driving the cylindrical workpiece to rotate are provided on the working base;

[0046] Furthermore, the loading assembly includes a first loading platform 11, a second loading platform 12 and a third loading platform 13, all of which are arranged in an inclined manner. The second loading platform 12 is located between the first loading platform 11 and the third loading platform 13, and the first loading platform 11 is arranged close to the transfer assembly; a first lifting driving member 121 is arranged on the working base below the first loading platform 11, and the table surface of the first loading platform 11 is higher than the third loading platform 13; the second loading platform 12 is suitable for accommodating a cylindrical workpiece;

[0047] The second loading platform 12 has an ascending state and a descending state under the drive of the first lifting drive member 121. When in the ascending state, the table extension surface of the second loading platform 12 is higher than or overlaps the table extension surface of the first loading platform 11. When in the descending state, the table extension surface of the second loading platform 12 is lower than or overlaps the table extension surface of the third loading platform 13.

[0048] In the above scheme, the staff puts multiple workpieces onto the third loading platform 13, and the third loading platform 13 is arranged at an angle. Under the action of gravity, the workpieces roll toward the second loading platform 12, and the workpiece at the front end is located on the second loading platform 12. At this time, the first lifting drive member 121 can drive the workpiece located thereon to rise and switch to the rising state. Since the second loading platform 12 is also arranged at an angle, after the second loading platform 12 rises, under the action of gravity, the workpiece continues to move forward to the first loading platform 11, and then further slides from the third loading platform 13 into the transfer assembly. The transfer assembly can drive the workpiece to rotate, and then cooperate with the subsequent polishing of the cylindrical casting. After the second loading platform 12 guides the workpiece to the first loading platform 11; in this scheme, multiple workpieces can be put in at one time, and there is no need to manually load them one by one, which effectively saves manpower. At the same time, it can also connect with the upstream unloading mechanism, providing a strong premise for realizing automated polishing.

[0049] It should be noted that this solution mainly provides assistance for the casting polishing device, which can be further understood as providing feeding assistance and rotation assistance. How the grinding mechanism performs grinding belongs to the more mature technology in the prior art, such as using a grinding wheel to act on the outer wall, end, inner wall, etc. of the workpiece. It does not belong to the main invention point of this solution, so this application will not further elaborate on this.

[0050] Specifically, in some of the embodiments, the first lifting drive member 121 may be a lifting drive cylinder or a lifting motor or other driving mechanism that can achieve lifting.

[0051] Specifically, the material transfer assembly includes a first fixed frame 31, a second fixed frame 32, a driving roller 33, a driven roller 34 and a rotating driving member 35;

[0052] Further, the first fixed frame 31 is disposed on the working base, the driving roller 33 is rotatably disposed on the first fixed frame 31, and the rotating driving member 35 is fixedly disposed on the first fixed frame 31 and is suitable for driving the driving roller 33 to rotate;

[0053] Specifically, the second fixing frame 32 is disposed on the working base, and the driven roller 34 is rotatably disposed on the second fixing frame 32;

[0054] Furthermore, the axial directions of the driving roller 33 and the driven roller 34 are parallel to each other, and the horizontal position of the highest point thereof is lower than the table surface of the first loading table 11, and the cylindrical workpiece is suitable for falling between the driving roller 33 and the driven roller 34;

[0055] In the above scheme, the workpiece further rolls from the first loading platform 11 to between the driving roller 33 and the driven roller 34. The driving roller 33 rotates under the action of the rotating drive member 35, thereby driving the workpiece to rotate. In this process, the driven roller 34 will also rotate to avoid excessive relative friction between the workpiece and the driven roller 34, thereby providing a certain degree of protection for the workpiece.

[0056] In some embodiments, the rotary drive member 35 includes a rotary motor.

[0057] For details, see Figure 1 , further comprising an auxiliary wheel 44 assembly; the auxiliary wheel 44 assembly comprises a first bracket 41, a second lifting drive member 42, a third fixed frame 43 and an auxiliary wheel 44; the auxiliary wheel is rotatably arranged on the third fixed frame 43, the third fixed frame 43 is connected to the driving end of the second lifting drive member 42, the second lifting drive member 42 is suitable for driving the auxiliary wheel 44 to rise and fall to abut against the outer wall of the cylindrical workpiece, the first bracket 41 is arranged on the working base, and the second lifting drive member 42 is fixedly arranged on the first bracket 41;

[0058] In the above scheme, after the workpiece falls between the driving roller 33 and the driven roller 34, the second lifting drive member 42 drives the third fixed frame 43 to move downward, so that the auxiliary wheel 44 abuts against the workpiece, and then cooperates with the driving roller 33 and the driven roller 34 to achieve the positioning of the workpiece. After further adding the auxiliary wheel 44, this scheme effectively improves the limiting stability of the workpiece, thereby improving the stability of the subsequent polishing process.

[0059] Specifically, a baffle 122 is provided below one end of the second loading platform 12 close to the third loading platform 13;

[0060] Further, when the second loading platform 12 is in the ascending state, it rises and blocks an end of the third loading platform 13 close to the second loading platform 12;

[0061] In the above scheme, when the second loading platform 12 rises, the baffle 122 connected thereto will also rise accordingly. In this way, after the second loading platform 12 switches to the rising state, the remaining workpieces are blocked by the baffle 122 and will not move further forward. After the second loading platform 12 moves downward, the baffle 122 moves downward accordingly. When the second loading platform 12 enters the descending state, the remaining workpieces will move further forward, moving forward one workpiece at a time, thereby realizing automatic material replenishment.

[0062] Specifically, a first linear drive member 36 is provided on the working base;

[0063] Furthermore, the second fixing frame 32 is disposed at the driving end of the linear driving member 36 , and the linear driving member 36 drives the driven roller 34 to approach or move away from the driving roller 33 ;

[0064] In the above scheme, the first intermediate driving member can drive the second fixed frame 32 to move, thereby driving the distance between the driving roller 33 and the driven roller 34 to change. For example, when encountering a cylindrical workpiece with a larger diameter, the distance between the driving roller 33 and the driven roller 34 can be increased. When encountering a workpiece with a smaller diameter, the distance between the driving roller 33 and the driven roller 34 can be reduced. The auxiliary device provided in this application can be adapted to the production and processing of more workpieces, thereby improving the compatibility of the device.

[0065] In some embodiments, the first linear drive member 36 includes a driving mechanism such as a linear drive motor and a drive cylinder.

[0066] Specifically, a material discharge port 21 is provided on the working base below the driving roller 33 and the driven roller 34;

[0067] Furthermore, a material discharge channel 20 communicating with the material discharge port 21 is provided in the working base;

[0068] In the above scheme, after the workpiece is processed, the first linear drive member 36 drives the second fixed frame 32 to move to drive the driven roller 34 away from the driving roller 33. When the two are away from each other to a certain extent, the workpiece will fall from between the driving roller 33 and the driven roller 34. The fallen workpiece enters the discharge channel 20 from the discharge port 21, and is finally guided to the designated position from the discharge channel 20 for centralized collection. There is no need to manually remove the processed workpiece, which further reduces manpower input, improves the degree of production automation, and effectively improves work efficiency.

[0069] Specifically, the first loading platform 11, the second loading platform 12 and the third loading platform 13 each include a base plate 51 and a limiting plate 52 disposed on the base plate 51;

[0070] For details, see Figure 2 , there are two limit plates 52 and they are arranged opposite to each other;

[0071] In the above scheme, the substrate 51 provides a supporting surface for the workpiece, and the two limiting plates 52 located on the substrate 51 can limit the workpiece, so that the multiple workpieces are arranged more neatly and orderly, thereby realizing stable automatic material replenishment.

[0072] Furthermore, a waist-shaped hole 511 is provided on the substrate 51 along its width direction;

[0073] For details, see Figure 3 , and also includes a fixing member suitable for penetrating the waist-shaped hole 511 and fixing the limiting plate 52 on the base plate 51;

[0074] In the above scheme, the staff can loosen the fixing parts so that the base plate 51 can be flexibly adjusted along the waist-shaped hole 511, and then tighten the fixing parts after adjusting to the appropriate position to fix the limit plate 52 and the base plate 51; this scheme can adjust the distance between the two limit plates 52 by adjusting the position of the limit plate 52, thereby adapting to cylindrical workpieces of different lengths and improving the application range of the device.

[0075] In one embodiment, the fixing member may be a locking screw; further, a threaded hole adapted to the locking screw is provided at the bottom end of the limiting plate 52 .

[0076] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application are within the scope of the technical solution of the present application.
