DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] See also Figure 1 to Figure 7 The present invention provides a casting surface polishing device, including a base 1, a polishing assembly 2 and a flipping assembly 3. The base 1 is arranged on the ground (or other supporting surface), a bracket 11 is fixedly connected to the middle of the top surface of the base 1, and the polishing assembly 2 is arranged on the bracket 11. An inclined boss 12 is fixedly connected to the top surface of the base 1 on one side of the bracket 11, and the inclined boss 12 is used to assist the casting to flip.

[0023] See also Figure 1 to Figure 7The polishing assembly 2 includes a lifting seat 21 and a driving shaft 211. The lifting seat 21 is slidably connected to the bracket 11. The driving shaft 211 is rotatably provided above the lifting seat 21. One end of the driving shaft 211 is rotatably connected to the side wall of one end of the lifting seat 21. The other end of the driving shaft 211 is connected to the output shaft of the main driving member 212. The main driving member 212 is installed on the side wall of the other end of the lifting seat 21 (there are many ways of installation, such as bolting, clamping, etc.). The main driving member 212 can drive the driving shaft 211 to reciprocate. A sleeve shaft 22 is rotatably sleeved on the driving shaft 211 (that is, the sleeve shaft 22 is rotatably connected to the outside of the driving shaft 211 through a bearing or other structure), and a positive ratchet is provided on the side wall of one end of the sleeve shaft 22. The positive ratchet, the sleeve shaft 22 and the driving shaft 211 are concentric. A positive ratchet pawl that can rotate in one direction is rotatably provided on the driving shaft 211. When the driving shaft 211 rotates forward, the positive ratchet cooperates with the positive ratchet pawl to drive the sleeve shaft 22 to rotate. Two active members 23 are symmetrically arranged on the sleeve shaft 22, and the active members 23 are slidably connected to the top surface of the lifting seat 21. Two first reciprocating grooves are arranged on the sleeve shaft 22 (the structure of which refers to the reciprocating screw rod). The active members 23 correspond to the first reciprocating grooves one by one. When the sleeve shaft 22 rotates, it can drive the two active members 23 to move synchronously in the opposite direction. The purpose of setting the first reciprocating groove is to achieve the reciprocating motion of the active members 23 when the sleeve shaft 22 rotates unidirectionally. The active members 23 are each provided with a central follower 24 on the side away from each other. The central follower 24 is each inserted on the sleeve shaft 22, and the central follower 24 is slidably connected to the lifting seat 21. A first spring is provided between the adjacent central follower 24 and the active member 23. A translation member 231 is provided between the adjacent center follower 24 and the active member 23. The horizontal height of the translation member 231 is higher than the horizontal heights of the active member 23 and the center follower 24 (the translation member 231 can be slidably connected to the top surface of the bracket 11). A lifting link 232 is rotatably provided between the translation member 231 and the active member 23, and between the translation member 231 and the center follower 24 (that is, one end of the lifting link 232 is rotatably connected to the translation member 231, and the other end of the lifting link 232 is rotatably connected to the active member 23 or the center follower 24). When the distance between the adjacent active member 23 and the center follower 24 becomes smaller (that is, the first spring is compressed), under the action of the lifting link 232, the distance between the translation member 231 and the active member 23 increases.

[0024] See also Figure 1 to Figure 7The side of the central follower 24 away from each other is provided with a side follower 25 slidably connected to the lifting seat 21, and the side follower 25 is inserted into the sleeve shaft 22.

Auxiliary parts 251, the other end of the clamping connecting rod 252 is rotatably connected to the side follower 25), push plates 253 are slidably provided on both sides of the top surface of the base 1, and auxiliary connecting rods 254 are provided between adjacent push plates 253 and the auxiliary parts 251 (that is, one end of the auxiliary connecting rod 254 is rotatably connected to the push plate 253, and the other end of the auxiliary connecting rod 254 is rotatably connected to the auxiliary part 251). When the two side followers 25 move away from each other, the two auxiliary parts 251 can be driven to move downward synchronously, thereby driving the two push plates 253 to move closer to each other. A slide groove is provided in the middle of the top surface of the base 1, and a bearing seat 26 is slidably provided in the slide groove. The bearing seat 26 is used to bear the casting. End plates 261 are provided on both sides of the top surface of the bearing seat 26. Two symmetrical clamping plates 262 are slidably provided on the top surface of the bearing seat 26. The clamping plates 262 are used to clamp and fix the casting. Connecting plates 263 passing through the end plates 261 are provided on the side walls of the clamping plates 262 away from the center of the bearing seat 26. The connecting plates 263 are slidably connected to the push plates 253, so that the connecting plates 263 can both slide back and forth along the push plates 253 and move synchronously with the push plates 253 to complete the clamping of the casting.

[0025] See also Figure 1 to Figure 7 A bottom driven shaft 28 is provided below the lifting seat 21, and both ends of the bottom driven shaft 28 are connected to the elastic support plate 282.

Since the positive ratchet and the counter ratchet are in opposite directions, the rotation directions of the positive ratchet and the counter ratchet are also opposite. When the driving shaft 211 is reversed, the counter ratchet and the counter ratchet cooperate to drive the driving gear 213 to rotate. A top driven shaft 29 is rotatably provided above the lifting seat 21 , and both ends of the top driven shaft 29 are rotatably connected to the side walls of the bracket 11 .

[0026] See also Figure 1 to Figure 7 The flip assembly 3 includes a threaded shaft 31 and a rotating plate 32. The threaded shaft 31 is rotatably arranged below the base 1. One end of the threaded shaft 31 is rotatably connected to the side wall of the base 1. The other end of the threaded shaft 31 is connected to the output shaft of the auxiliary driving member, and the auxiliary driving member is arranged on the side wall of the other end of the base 1. A threaded seat (not shown in the figure) is threadedly connected to the threaded shaft 31. The top surface of the threaded seat is rotatably connected to the rotating plate 32. The first torsion spring is provided at the connection between the rotating plate 32 and the threaded seat. When the first torsion spring is in a natural state, the rotating plate 32 is in a vertical state. The top end of the rotating plate 32 passes through the bearing seat 26. The bearing seat 26 is provided with an avoidance groove that can cooperate with the rotating plate 32. The avoidance groove is open at one end close to the inclined protrusion 12. When the casting is fixed on the bearing seat 26, under the action of the rotating plate 32, the threaded seat can drive the bearing seat 26 and the casting to reciprocate. A side driven shaft 34 is rotatably provided on the inclined boss 12, and both ends of the side driven shaft 34 are rotatably connected to the vertical plates, and the vertical plates are fixedly connected to the base 1. A flip plate 341 is fixedly connected to the side driven shaft 34, and a second torsion spring is provided at the connection between the side driven shaft 34 and the inclined boss 12. When the second torsion spring is in a natural state, the flip plate 341 does not cooperate with the casting, and one end of the side driven shaft 34 is connected to a side driven gear 342, and an optical axis is rotatably provided on the vertical plate close to the side driven gear 342, and a transmission gear 35 that can mesh with the side driven gear 342 is provided on the optical axis, and a first belt is provided between the optical axis and the top driven shaft 29.

[0027] See also Figure 1 to Figure 7 Preferably, the top surface of the polishing seat 272 is rotatably connected to an auxiliary gear 273 through a rotating shaft, and a second belt is provided between the rotating shaft and the vertical shaft 271 (the user can adjust the wrap angle of the second belt according to the existing technology or replace the second belt with a chain to ensure good transmission efficiency. This is the existing technology, so it will not be repeated), and the bottom surface of the lifting seat 21 is provided with a rack that can mesh with the auxiliary gear 273. When the lifting seat 21 descends to the polishing seat 272 abuts against the casting surface, the driving gear 213 meshes with the bottom driven gear 281, and the auxiliary gear 273 meshes with the rack, so that the polishing seat 272 can rotate during the reciprocating motion of the reciprocating seat 27 (adjust the tooth density on the auxiliary gear 273 and the rack to achieve high-speed rotation of the polishing seat 272, or cancel the setting of the auxiliary gear 273 and the rack, and use a small motor to directly drive the polishing seat 272 to rotate. This is all existing technology, so it will not be repeated), thereby improving the polishing efficiency.

[0028] See also Figure 1 to Figure 7 Preferably, the push plate 253 is provided with a guide groove that cooperates with the connecting plate 263, and the connecting plate 263 is provided with a clamping plate 264 that can cooperate with the push plate 253, thereby improving the smoothness of the movement of the connecting plate 263.

[0029] See also Figure 1 to Figure 7 Preferably, a plurality of rollers 33 are rotatably provided on one side of the rotating plate 32 close to the inclined boss 12, and the rollers 33 can reduce the friction between the rotating plate 32 and the casting, thereby providing protection for the casting.

[0030] See also Figure 1 to Figure 7 Preferably, the main driving member 212 and the auxiliary driving member are both rotating motors that can provide sufficient power.

[0031] See also Figure 1 to Figure 7 Preferably, a gear tooth area and a blank area are provided on the surface of the transmission gear 35. When the gear tooth area is engaged with the side driven gear 342, the transmission gear 35 can drive the side driven gear 342 to rotate. When the blank area cooperates with the side driven gear 342, the side driven shaft 34 can automatically rotate and reset under the action of the second torsion spring.

[0032] During the implementation of the present invention, the user places the casting on the top surface of the bearing seat 26, starts the main driving member 212, and the main driving member 212 rotates forward. At this time, the positive ratchet cooperates with the positive pawl, and the reverse ratchet does not cooperate with the reverse pawl. The sleeve shaft 22 rotates, and the driving gear 213 does not rotate. The two active members 23 move away from each other, thereby driving the two side driven members 25 to move away from each other, causing the auxiliary member 251 to descend, and the two push plates 253 approach each other (during this period, the first spring does not deform), so that the clamping plate 262 clamps the casting, and then the two active members 23 continue to move away from each other until the first spring is compressed, and the distance between the adjacent active members 23 and the center driven member 24 is reduced. Under the action of the lifting connecting rod 232, the lifting seat 2 1 descends, so that the driving gear 213 meshes with the bottom driven gear 281, and the auxiliary gear 273 meshes with the rack (if the polishing seat 272 does not abut the casting at this time, the lifting seat 21 can continue to descend, and the third spring is compressed). When the polishing seat 272 abuts the casting, the main driving member 212 reverses. At this time, the positive ratchet does not cooperate with the positive pawl, the reverse ratchet cooperates with the reverse pawl, and the sleeve shaft 22 does not rotate. The driving gear 213 drives the bottom driven shaft 28 to rotate, thereby causing the reciprocating seat 27 to reciprocate, driving the polishing seat 272 to rotate and reciprocate at the same time to polish the surface of the casting. During this period, the auxiliary driving member is started, driving the threaded shaft 31 to rotate, and the threaded seat drives the rotating plate 32 to move, and the rotating plate 32 pushes the casting to move. When When the surface polishing of one side of the casting is completed, the bearing seat 26 is located at one end of the slide groove close to the inclined protrusion 12, and the main driving member 212 rotates forward, so that the lifting seat 21 rises to the driving gear 213 and meshes with the top driven gear 291. At this time, the clamping plate 262 is disengaged from the casting, and then the auxiliary driving member drives the threaded shaft 31 to rotate, so that the rotating plate 32 pushes the casting to move alone and cooperate with the inclined protrusion 12, and the casting changes from a horizontal state to an inclined state. Then the main driving member 212 is reversed to rotate the top driven shaft 29, and the top driven shaft 29 drives the optical axis to rotate. At this time, the gear area of ​​the transmission gear 35 is meshed with the side driven gear 342, so that the side driven shaft 34 drives the flip plate 341 to rotate. In this process, the casting is located on the flip plate 341. When the flip plate 341 rotates to a horizontal state, the casting is flipped. At this time, the rotating plate 32 is located below the casting, the rotating plate 32 is in a horizontal state and the roller 33 thereon abuts against the casting. The auxiliary driving part reverses to make the threaded seat move in the opposite direction until the rotating plate 32 is disengaged from the casting. Under the action of the first torsion spring, the rotating plate 32 is reset, and then the main driving part 212 reverses to make the blank area of ​​the transmission gear 35 cooperate with the side driven gear 342. The flip plate 341 rotates and resets, and then the main driving part 212 rotates forward to make the lifting seat 21 descend, and the polishing seat 272 can polish the surface of the casting after it is flipped. The auxiliary driving part starts to drive the casting to move until the polishing operation is completed on both sides of the casting.

[0033] The present invention provides a casting surface polishing device, which has the following beneficial effects: 1. By setting up the polishing assembly, the reciprocating motion and rotation of the polishing disc can be combined to improve the polishing effect, and it can also be applied to castings of different widths and thicknesses, expanding the scope of application of the device.

[0034] 2. By setting up a flip component, the casting can be automatically flipped and double-sided polished, which reduces the labor intensity of the user and improves the efficiency of the polishing operation.

[0035] In summary, the beneficial effects of the present invention are: it can be applied to castings of different widths and thicknesses, expanding the application range of the device, and can combine the reciprocating motion and rotation of the polishing disc to perform double-sided polishing on the castings, reducing the labor intensity of the user and improving the efficiency of the polishing operation.

[0036] Of course, the present invention may have a variety of embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
