[0002] When grinding the inner wall of a workpiece, the abrasive must be placed into the opening of the workpiece. The grinding effect is achieved by the movement of the abrasive within the workpiece. After grinding is complete, the abrasive must be removed from the workpiece.

[0003] On conventional production lines, it is common practice to have workers manually pour abrasive materials. This method not only consumes a significant amount of workers' time and energy but also results in very low work efficiency. Summary of the Invention

The receiving platform can change to a horizontal or inclined state under the drive of the flipping drive mechanism. When the receiving platform is in a horizontal state, it facilitates the placement of workpieces and the fixing of workpieces by the clamp. When the receiving platform is in an inclined state, the opening of the workpiece faces downward and toward the material frame, and the abrasive in the workpiece can be poured into the material frame.

[0006] Furthermore, the receiving platform includes: a mounting frame and a platform, the platform being rotatably mounted on the mounting frame and used to place workpieces; a flipping drive mechanism for driving the platform to rotate relative to the mounting frame; a support wheel, rotatably mounted on the platform; and a wheel rotation drive assembly for driving the support wheel to rotate; after the workpiece is placed on the platform, it contacts the wheel surface of the support wheel, and the support wheel lifts the workpiece; during the unloading process, the support wheel rotates, driving the workpiece to rotate, thereby promoting the outflow of abrasive from the workpiece.

[0007] Furthermore, the platform is equipped with two sets of support wheels, which are spaced apart. After the workpiece is placed on the platform, it is located between the two sets of support wheels; at least one set of support wheels can rotate under the drive of the wheel rotation drive assembly.

[0008] Furthermore, the support wheel includes: an axle rotatably mounted on the platform; at least two rollers sleeved on the axle for supporting the workpiece; a wheel rotation drive assembly for driving the axle to rotate, thereby causing the rollers to rotate accordingly; the wheel rotation drive assembly includes: a roller drive member, the fixed end of which is mounted on the platform, and the movable end of which has a driving wheel; a driven wheel sleeved on the axle; and a transmission bar sleeved on the driving wheel and the driven wheel; during operation, the roller drive member drives the driving wheel to rotate, which in turn drives the driven wheel to rotate via the transmission bar, and the driven wheel drives the axle to rotate.

[0009] Furthermore, the fixture includes: a first clamping assembly and a second clamping assembly, the first clamping assembly and the second clamping assembly being disposed opposite to each other along a first direction and slidably disposed on the receiving platform; a clamping drive assembly for driving the first clamping assembly and the second clamping assembly to move closer to each other or further away from each other along the first direction; when the first clamping assembly and the second clamping assembly move closer to each other, they can hold the workpiece on the receiving platform tightly; when the first clamping assembly and the second clamping assembly move further away from each other, they can release the workpiece that has been unloaded so that a new workpiece to be unloaded can be inserted.

[0010] Furthermore, the first clamping assembly and / or the second clamping assembly includes: a clamping mounting frame slidably disposed on the receiving platform; and a clamping roller rotatably disposed on the clamping mounting frame; when the clamp holds the workpiece, the wheel surface of the clamping roller abuts against the workpiece.

[0011] Furthermore, the clamping mounting frame is equipped with two sets of clamping rollers, which are spaced apart in the vertical direction; on the same clamping mounting frame, the clamping rollers are positioned further forward to facilitate clamping large workpieces.

[0012] Furthermore, the clamping drive assembly includes: a clamping drive member, the fixed end of which is disposed on the receiving platform, and the movable end which is connected to the first clamping assembly or the second clamping assembly; a gear, which is rotatably disposed on the receiving platform; a first rack, which is connected to the first clamping assembly; and a second rack, which is connected to the second clamping assembly. Both the first rack and the second rack mesh with the gear, and are symmetrically arranged with the gear as a point and center. In use, the clamping drive member drives the first clamping assembly or the second clamping assembly connected to it to move along a first direction, and through the gear and rack structure transmission, the first clamping assembly and the second clamping assembly move relative to each other.

[0013] Furthermore, the material frame includes: a frame body located on one side of the receiving platform, with the top of the frame body open for feeding abrasive; and a material barrier post located in the frame body, which can block the workpiece after the receiving platform is tilted, thereby preventing the workpiece from falling.

[0014] Furthermore, the material frame also includes: a frame bottom, located at the bottom of the frame body, with the diameter of the frame bottom gradually decreasing from top to bottom to facilitate the collection of abrasive material fed into the frame; and / or a guardrail, located at the top of the frame body, used to raise the frame body to prevent abrasive material from splashing out during the pouring process.

[0015] This application provides a post-grinding material unloading machine, including a receiving platform, a clamp, a material frame, and a tilting drive mechanism. The clamp is disposed on the receiving platform and is used to fix the workpiece. The tilting drive mechanism is used to drive the receiving platform to tilt towards the material frame, so that the workpiece on the receiving platform changes from a flat state to an inverted state, with the opening of the workpiece facing downwards and directly facing the material frame. Under the action of gravity, the abrasive in the workpiece can fall into the material frame through the opening. The post-grinding material unloading machine provided by this application, by setting a tiltable receiving platform and fixing the workpiece with the clamp, can tilt the workpiece by tilting the receiving platform, so that the opening of the workpiece tilts downwards towards the material frame, so that the abrasive in the workpiece can be discharged into the material frame from the opening. The post-grinding material unloading machine provided by this application has a simple and clear structure, is easy to operate, and can significantly improve the unloading efficiency.

[0019] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0020] This application provides a grinding and pouring machine, including: a receiving platform 10 for receiving workpieces to be poured; a clamp 20 disposed on the receiving platform 10 for fixing the workpieces; a material frame 30 disposed on one side of the receiving platform 10 for receiving abrasive; and a flipping drive mechanism 40 for driving the receiving platform 10 to flip toward the material frame 30. The receiving platform 10 can change to a horizontal state or an inclined state under the drive of the flipping drive mechanism 40. When the receiving platform 10 is in a horizontal state, it facilitates the placement of workpieces and the fixing of workpieces by the clamp 20. When the receiving platform 10 is in an inclined state, the opening of the workpiece faces downward and toward the material frame 30, and the abrasive in the workpiece can be poured into the material frame 30.

[0021] The flipping drive mechanism 40 can be a motor coupled with a rotating shaft, or it can be a swing strut, etc. This application does not limit the specific configuration of the flipping drive mechanism 40, as long as it can achieve the flipping of the receiving platform 10 relative to the material frame 30.

[0022] At the start of operation, the receiving platform 10 is in a horizontal position. At this time, the platform for placing the workpiece extends horizontally, allowing workers or handling equipment (such as robots or robotic arms) to smoothly place the workpiece onto it. The clamp 20 activates and grips the workpiece, thus fixing it to the receiving platform 10. At this time, the opening of the workpiece points towards the material frame 30. The flipping drive mechanism 40 activates, causing the receiving platform 10 and clamp 20 to flip towards the material frame 30, changing the receiving platform 10 to an inclined state. The workpiece on it changes from a flat position to an inverted position, with its opening facing downwards and directly towards the material frame 30. Under the influence of gravity, the abrasive in the workpiece falls into the material frame 30 through the opening.

[0023] It should be added that after the receiving platform 10 enters the tilted state, the workpiece can extend vertically or at an angle to the vertical direction, as long as the bottle mouth of the workpiece faces downwards, so that the abrasive can slide out from the outlet.

[0024] In one specific embodiment, after the receiving platform 10 enters the tilted state, the platform for placing the workpiece on the receiving platform 10 extends vertically, the workpiece on the receiving platform 10 is in a 90° inverted state, and the opening of the workpiece is vertically downward.

[0025] The grinding post-pouring machine provided in this application features a tiltable receiving platform 10. After the workpiece is fixed in place by the clamp 20, the tilting of the receiving platform 10 tilts the workpiece, causing the opening of the workpiece to tilt downwards towards the material frame 30, so that the abrasive inside the workpiece can be discharged into the material frame 30 from the opening. The grinding post-pouring machine provided in this application has a simple and clear structure, is easy to operate, and can significantly improve the pouring efficiency.

[0026] In one embodiment, the receiving platform 10 includes a mounting frame 11 and a platform 12. The platform 12 is rotatably mounted on the mounting frame 11 and is used to place workpieces. The flipping drive mechanism 40 is used to drive the platform 12 to rotate relative to the mounting frame 11.

[0027] For details, please refer to Figure 1 In the illustrated embodiment, the top of the mounting frame 11 is rectangular, and the platform 12 is rotatably mounted within the frame via a pivot. The mounting frame 11 elevates the platform 12, providing space for it to be rotated. The rotation drive mechanism 40 is a motor, with its fixed end located on one side of the mounting frame 11 and its movable end connected to the pivot. When the shape of the receiving platform 10 needs to be changed, the rotation drive mechanism 40 is activated, causing the pivot to rotate and thus rotating the platform 12 relative to the mounting frame 11.

[0028] Furthermore, the receiving platform 10 also includes: support wheels 13, which are rotatably mounted on the platform 12;

[0029] The wheel rotation drive assembly 14 is used to drive the support wheel 13 to rotate. After the workpiece is placed into the platform 12, it contacts the wheel surface of the support wheel 13, and the support wheel 13 lifts the workpiece. During the unloading process, the support wheel 13 rotates and drives the workpiece to rotate, thereby promoting the outflow of abrasive in the workpiece.

[0030] The wheel rotation drive assembly 14 can be any drive structure capable of supporting the rotation of the wheel 13, such as a rotary cylinder or a motor.

[0031] For details, please refer to Figure 1 In the illustrated embodiment, the platform 12 is also frame-shaped, and the support wheel 13 is rotatably disposed within the frame. The support wheel 13 protrudes from the platform 12; the workpiece is fixed on the wheel surface of the support wheel 13 by the clamp 20. At this time, the workpiece is suspended above the platform 12, which facilitates the workpiece falling towards the material frame 30 when it is flipped. At the same time, the contact area between the wheel surface of the support wheel 13 and the workpiece is small, and the clamp 20 can clamp the lower surface of the workpiece, which is beneficial to the reliability of clamping.

[0032] Continue to refer to Figure 1 The wheel rotation drive assembly 14 is connected to the wheel axle of the support wheel 13, which can drive the support wheel 13 to rotate. This allows the support wheel 13 to rotate. When the workpiece is a cylindrical structure (such as a long bottle, a barrel, etc.), during the pouring process, the support wheel 13 can drive the workpiece to rotate through friction, thereby promoting the outflow of abrasive in the workpiece and preventing the opening of the workpiece from being blocked.

[0033] Optionally, the platform 12 is provided with two sets of support wheels 13, which are spaced apart. After the workpiece is placed on the platform 12, it is located between the two sets of support wheels 13; at least one set of support wheels 13 can rotate under the drive of the wheel rotation drive assembly 14.

[0034] It is easy to understand that when the two sets of support wheels 13 are spaced apart, there is a V-shaped receiving space between them, which can be used to accommodate the workpiece. When the workpiece is a cylindrical structure, the two sets of support wheels 13 can cooperate to support and constrain the workpiece, preventing the workpiece from rolling on the receiving table 10.

[0035] Optionally, the support wheel 13 includes: a wheel axle, rotatably mounted on the platform 12; at least two rollers, sleeved on the wheel axle, for supporting the workpiece; and a wheel rotation drive assembly 14 for driving the wheel axle to rotate, thereby causing the rollers to rotate as well.

[0036] Arranging multiple rollers coaxially ensures the synchronization of roller rotation, thereby ensuring the uniformity of the overall rotation of the workpiece; it also eliminates the need to create additional molds to manufacture long rollers to accommodate long workpieces, which is beneficial for parts procurement and cost reduction.

[0037] Optionally, the wheel rotation drive assembly 14 includes: a roller drive component 14a, the fixed end of which is disposed on the platform 12, and the movable end of which is provided with a drive wheel 14b; a driven wheel, which is sleeved on the wheel axle; and a transmission bar 14c, which is sleeved on the drive wheel 14b and the driven wheel. During operation, the roller drive component 14a drives the drive wheel 14b to rotate, and through the transmission bar 14c, drives the driven wheel to rotate, and the driven wheel drives the wheel axle to rotate.

[0038] For details, please refer to Figure 2 In the illustrated embodiment, the roller drive 14a is a motor, and is fixedly mounted on the back of the platform 12. The transmission bar 14c is a chain, and the driving wheel 14b and the driven wheel are sprockets. The driven wheel is sleeved on the axle and located between the two rollers. The diameter of the driven wheel is smaller than that of the roller. When the rollers support the workpiece, the driven wheel and the transmission bar 14c will not interfere with the workpiece. During the unloading process, the roller drive 14a drives the driving wheel 14b to rotate, which in turn drives the driven wheel to rotate via the transmission bar 14c. The driven wheel then drives the axle to rotate, causing multiple rollers on the same axle to rotate. The rollers abut against the workpiece, and under the action of friction, the rollers drive the workpiece to rotate, thereby promoting the discharge of abrasive material from the workpiece.

[0039] In one embodiment, the clamp 20 includes: a first clamping component 20A and a second clamping component 20B, the first clamping component 20A and the second clamping component 20B being arranged opposite to each other along a first direction and slidably disposed on the receiving platform 10; and a clamping drive component 23, used to drive the first clamping component 20A and the second clamping component 20B to move closer to each other or further away from each other along the first direction; when the first clamping component 20A and the second clamping component 20B move closer to each other, they can hold the workpiece on the receiving platform 10 tightly; when the first clamping component 20A and the second clamping component 20B move further away from each other, they can release the workpiece that has been unloaded so that a new workpiece to be unloaded can be placed in.

[0040] The first direction is the direction that is horizontal and perpendicular to the direction from the workpiece to the material frame 30.

[0041] For ease of understanding, assume the opening is located at one end of the workpiece's length direction, and the material frame 30 is positioned outside the opening along its length. To avoid the opening, the first clamping assembly 20A and the second clamping assembly 20B need to be positioned on both sides of the workpiece's width direction. In this case, the first direction is the workpiece's width direction.

[0042] The clamping drive assembly 23 can be a single-drive form, such as a dual-output cylinder or a motor with a dual-screw, or it can be a dual-drive form, driving the first clamping assembly 20A and the second clamping assembly 20B to move along a first direction respectively. This application does not limit the specific configuration of the clamping drive assembly 23. The clamping drive assembly 23 can be used to realize the synchronous relative movement of the first clamping assembly 20A and the second clamping assembly 20B, or it can be used only to realize the translation of one of the first clamping assembly 20A and the second clamping assembly 20B.

[0043] After the workpiece is placed into the receiving platform 10, it is positioned between the first clamping assembly 20A and the second clamping assembly 20B. The clamping drive assembly 23 drives the first clamping assembly 20A and the second clamping assembly 20B to move towards each other, so that the first clamping assembly 20A and the second clamping assembly 20B can cooperate to hold the workpiece and fix it on the receiving platform 10. The receiving platform 10 flips over to complete the workpiece unloading. After the receiving platform 10 returns to its original position with the workpiece, the clamping drive assembly 23 drives the first clamping assembly 20A and the second clamping assembly 20B to move away from each other, so that the first clamping assembly 20A and the second clamping assembly 20B can release the workpiece. The unloaded workpiece is removed, and a new, unloaded workpiece can be placed between the first clamping assembly 20A and the second clamping assembly 20B.

[0044] In one specific embodiment, the first clamping assembly 20A and / or the second clamping assembly 20B include: a clamping mounting frame 21, which is slidably disposed on the receiving platform 10; and a clamping roller 22, which is rotatably disposed on the clamping mounting frame 21; when the clamp 20 holds the workpiece, the wheel surface of the clamping roller 22 abuts against the workpiece.

[0045] When the receiving platform 10 is equipped with a support wheel 13, and the support wheel 13 can drive the workpiece to rotate and pour under the drive of the wheel rotation drive assembly 14, a pair of clamping rollers 22 are set to cooperate and press against the workpiece, ensuring that the axis of the clamping rollers 22 is parallel to the axis of the support wheel 13. The clamping rollers 22 can not only fix the workpiece, but also offset the friction between themselves and the workpiece by rotating, and prevent the workpiece from being worn by the clamp 20.

[0046] Optionally, the clamping mounting frame 21 is provided with two sets of clamping rollers 22, which are arranged at intervals in the vertical direction; on the same clamping mounting frame 21, the clamping rollers 22 are installed at the front to facilitate clamping large workpieces.

[0047] For details, please refer to [the following]. Figure 2 In the illustrated embodiment, the clamp 20 includes two pairs of clamping rollers 22, which are arranged at intervals in the vertical direction. The distance between the upper pair of clamping rollers 22 is smaller than the distance between the lower pair of clamping rollers 22.

[0048] It's easy to understand that larger workpieces are also taller. Therefore, when unloading workpieces of different sizes, a pair of clamping rollers 22 positioned on top can be used to clamp larger workpieces, while another pair of clamping rollers 22 positioned below can be used to clamp smaller workpieces. When the lower pair of clamping rollers 22 clamps a smaller workpiece, the height of the smaller workpiece is lower than the upper pair of clamping rollers 22. Therefore, the upper pair of clamping rollers 22 will not interfere with the fixture 20's fixation of the smaller workpiece.

[0049] In one specific embodiment, the clamping drive assembly 23 includes: a clamping drive member 23a, the fixed end of which is disposed on the receiving platform 10, and the movable end which is connected to the first clamping assembly 20A or the second clamping assembly 20B; a gear 23b, which is rotatably disposed on the receiving platform 10; a first rack 23c, which is connected to the first clamping assembly 20A; and a second rack 23d, which is connected to the second clamping assembly 20B. Both the first rack 23c and the second rack 23d mesh with the gear 23b, and the two are symmetrically arranged with the gear 23b as a point and center. In use, the clamping drive member 23a drives the first clamping assembly 20A or the second clamping assembly 20B connected to it to move along a first direction. Through the gear and rack structure transmission, the first clamping assembly 20A and the second clamping assembly 20B move relative to each other.

[0050] The clamping drive component 23a can be any drive component, such as a cylinder or an electric cylinder, that can drive the first clamping component 20A or the second clamping component 20B to move linearly in the first direction.

[0051] For details, please refer to Figure 2 In the illustrated embodiment, platform 12 has a symmetrical grid-shaped structure. Two sets of guide rails are arranged in the middle of platform 12. Either guide rail extends along a first direction, and the two sets of guide rails are spaced apart along a second direction, which is horizontal and perpendicular to the first direction. Gear 23b, first rack 23c, and second rack 23d are positioned between the two sets of guide rails. Gear 23b is located at the center, and first rack 23c and second rack 23d are arranged opposite each other along the second direction. Both first rack 23c and second rack 23d extend along the first direction.

[0052] Combined with reference Figure 3 The clamping drive component 23a is fixedly mounted on the back of the platform 12; the platform 12 is provided with a vertical through hole, and the movable end of the clamping drive component 23a is connected to the first clamping assembly 20A through the through hole.

[0053] During operation, the clamping drive 23a drives the first clamping assembly 20A to translate toward the second clamping assembly 20B. The first rack 23c follows, simultaneously driving the gear 23b to rotate. The gear 23b further drives the second rack 23d and the second clamping assembly 20B to translate toward the first clamping assembly 20A. Thus, the first clamping assembly 20A and the second clamping assembly 20B move toward each other, so that the fixture 20 can hold the workpiece. After unloading and the receiving table 10 returns to a horizontal state, the clamping drive 23a drives the first clamping assembly 20A to translate away from the second clamping assembly 20B. The first rack 23c follows, simultaneously driving the gear 23b to rotate. The gear 23b further drives the second rack 23d and the second clamping assembly 20B to translate away from the first clamping assembly 20A. Thus, the first clamping assembly 20A and the second clamping assembly 20B move in opposite directions, so that the fixture 20 can release the workpiece.

[0054] In one embodiment, the material frame 30 includes: a frame body 31, disposed on one side of the receiving platform 10, with the top of the frame body 31 open for feeding abrasive; and a material barrier post 32, disposed in the frame body 31, which can block the workpiece after the receiving platform 10 is tilted, thereby preventing the workpiece from falling.

[0055] For details, please refer to Figure 1 In the illustrated embodiment, the frame 31 is located on the front side of the receiving platform 10 and surrounds the front end of the receiving platform 10; thus, after the receiving platform 10 is flipped toward the material frame 30, it can ensure that the workpiece is facing the frame 31.

[0056] Combined with reference Figure 3 The front end of the receiving platform 10 is provided with an installation plate. The material bar 32 is fixedly installed on the installation plate and suspended in the frame 31. After the receiving platform 10 is flipped toward the material frame 30, the workpiece can abut against the material bar 32. The material bar 32 can not only cooperate with the clamp 20 to fix the workpiece, but also limit the flipping angle of the workpiece to avoid excessive flipping of the workpiece and affecting the abrasive discharge.

[0057] When the receiving platform 10 is equipped with a support wheel 13, and the support wheel 13 can drive the workpiece to rotate and pour material under the drive of the wheel rotation drive assembly 14, the material bar column 32 is set in the form of a rotating shaft; in this way, when the workpiece rotates, the material bar column 32 can offset the friction between itself and the workpiece by rotating with it, which is conducive to promoting the rotation and discharge of the workpiece, and can also avoid mutual wear with the workpiece.

[0058] Optionally, the feed frame 30 also includes a frame bottom, located at the bottom of the frame body 31. The diameter of the frame bottom gradually decreases from top to bottom to facilitate the collection of abrasive material fed into the feed frame 30.

[0059] The bottom of the frame can be closed, in which case the material frame 30 can be used to store abrasive; the bottom of the frame can also be open, so as to discharge abrasive outwards.

[0060] The bottom of the frame is designed to taper, with a sloping bottom surface, which facilitates abrasive discharge and avoids residual abrasive at corners.

[0061] Optionally, the material frame 30 also includes a guardrail 33 at the top of the frame 31 to raise the frame 31, thereby preventing the abrasive from splashing out during the pouring process.

[0062] When abrasive particles fall, they tend to bounce back when they hit the wall. Setting up guardrails 33 can prevent abrasive particle loss and improve workshop safety.

[0063] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
