[0001] The present invention relates to the structure of a grinding machine, and particularly to a locking mechanism and a grinding machine. Background Art

[0002] A grinding machine is a grinding device. Structurally, it usually has a base and a translation base. The translation base is provided with a grinding wheel for grinding. The base is provided with a screw assembly and a motor for driving the translation base to move. The top of the base is also provided with a guide rail for supporting the translation base, and the guide rail realizes the sliding connection between the translation base and the base.

[0003] During use, the motor drives the screw assembly, and the screw assembly drives the translation base to move. The translation base performs linear translation along the guide rail. Furthermore, the grinding wheel approaches and contacts the product, and the grinding wheel grinds the product.

[0004] However, the reaction force during grinding causes the translation base to shake, and it is also easy to damage the screw assembly, resulting in inaccurate movement of the translation base and affecting the grinding quality. Summary of the Invention

[0005] An object of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide a locking mechanism and a grinding machine, which can firmly lock the translation base, reduce the shaking of the translation base, avoid damage to the screw assembly, and at the same time ensure the grinding quality.

[0006] The present invention is achieved by the following technical solutions:

[0007] In a first aspect of the present invention, a locking mechanism is provided, including a base and a translation base. A locking component is arranged between the base and the translation base. The locking component includes an inflatable member and a pressing block. The inflatable member abuts against the pressing block, the inflatable member drives the pressing block to move, the pressing block abuts against the base or the translation base, and the inflatable member and the pressing block cooperate to fix the translation base to the base.

[0008] According to a locking mechanism described in the first aspect of the present invention, the inflatable member and the pressing block are in a strip shape, and the length direction of the inflatable member and the pressing block is arranged along the moving direction of the translation base.

[0009] According to a locking mechanism described in the first aspect of the present invention, the inflatable member and the pressing block are arranged on one side of the base in the horizontal direction.

[0010] According to a locking mechanism described in the first aspect of the present invention, the translation base is provided with two opposite lower suspension plates. The base is accommodated between the two lower suspension plates, and the inflatable member and the pressing block are arranged between the lower suspension plates and the base.

[0011] A locking mechanism according to the first aspect of the present invention, wherein the lower suspension plate is provided with a stepped hole, the large end of the stepped hole is arranged on the side of the lower suspension plate away from the base, the stepped hole is used to install the pressing block and the air expansion member, and the air expansion member is located on the side of the pressing block away from the base.

[0012] A locking mechanism according to the first aspect of the present invention further includes a semi-tube for accommodating the air expansion member, and the semi-tube is arranged on the side of the air expansion member away from the pressing block.

[0013] A locking mechanism according to the first aspect of the present invention further includes a mounting strip extending along the outer surface of the semi-tube, the mounting strip extends along the circumferential direction of the semi-tube, and both ends of the mounting strip are fixed to the lower suspension plate.

[0014] A locking mechanism according to the first aspect of the present invention, a side guide rail is provided between the side of the base and the lower suspension plate.

[0015] A locking mechanism according to the first aspect of the present invention, the air expansion member and the pressing block are arranged above the side guide rail.

[0016] The second aspect of the present invention is to provide a grinding machine, including a locking mechanism according to any one of the above.

[0017] Beneficial effects: Compared with the prior art, a locking mechanism and a grinding machine of the present invention are provided with a locking component, and the locking component has a pressing block. Thus, when the reaction force during grinding causes a relative movement tendency between the translation seat and the base, the pressing block presses the base or the translation seat, so that a frictional force is generated between the pressing block and the base or the translation seat. Furthermore, the relative movement between the translation seat and the base is prevented. Therefore, the translation seat can be firmly locked, the shaking of the translation seat is reduced or even avoided, and the screw component is protected from damage. This not only ensures the accurate movement of the translation seat but also guarantees the grinding quality.

[0018] At the same time, a locking mechanism and a grinding machine of the present invention are provided with an air expansion member to drive the pressing block to generate extrusion. Thus, the pressing block is evenly pressed, ensuring sufficient and more uniform contact area and extrusion force between the pressing block and the base or the translation seat. Furthermore, the frictional force is increased, making the translation seat and the base more firmly locked together, further protecting the screw component and further improving the grinding quality.

[0029] Referring to Figure 1 , an embodiment of a grinding machine is provided. Structurally, there are mainly a conveying mechanism 320 and two grinding mechanisms 330. The two grinding mechanisms 330 are relatively arranged on both sides of the conveying mechanism 320.

[0030] During use, the conveying mechanism 320 conveys the product, and the product passes between the two grinding mechanisms 330. Furthermore, one grinding mechanism 330 grinds one side of the product, and one grinding mechanism 330 grinds the other side of the product.

[0031] Referring to Figure 2 and Figure 3 , this embodiment also provides an arrangement structure of the grinding mechanism 330 part of the grinding machine.

[0032] Specifically, the arrangement structure of this embodiment includes a base 100 and a translation base 110. Among them, the translation base 110 is installed on the base 100, and the translation base 110 is used to install the grinding wheel and the motor that drives the grinding wheel.

[0033] Structurally, the base 100 is provided with a screw rod assembly 220220 that drives the translation base 110 to move linearly, and a driving motor that drives the screw rod of the screw rod assembly 220220 to rotate.

[0034] Alternatively, the screw rod assembly 220220 can be a combination of a screw rod and a nut, or a ball screw structure, which is convenient for standardized manufacturing.

[0035] In order to ensure that the translation base 110 moves linearly, an upper guide rail 120 is provided between the bottom of the translation base 110 and the top of the base 100. Preferably, two upper guide rails 120 are provided.

[0036] In some preferred embodiments, two second bosses 210 can be provided on the top of the base 100. One upper guide rail 120 is provided on one second boss 210, and the screw rod assembly 220220 is located between the two second bosses 210.

[0037] Providing two upper guide rails 120 can achieve two-point support, increase the stability of the translation base 110, reduce the sway perpendicular to the translation direction. At the same time, providing two second bosses 210 leaves a space for installing the screw rod assembly 220220 between the two second bosses 210, without increasing the height of the translation base 110, ensuring a low center of gravity and making the grinding machine more stable.

[0038] In some preferred embodiments, the translation base 110 can be provided with a bottom plate 230, and the upper guide rail 120 is mounted on the bottom surface of the bottom plate 230.

[0039] Therefore, it is not necessary to disassemble the upper guide rail 120, and the grinding wheel, motor, etc. can be removed, which is convenient for maintenance.

[0040] In some preferred embodiments, the translation base 110 can further include a mounting frame 240. The mounting frame 240 mounts the grinding wheel and the motor. A third groove 250 is provided on the top surface of the bottom plate 230, and a cushion block 260 is provided in the third groove 250. The cushion block 260 supports and connects the mounting frame 240.

[0041] Therefore, by providing the cushion block 260 to support the mounting frame 240, the cushion block 260 is used to absorb vibration energy, reduce vibration, and delay the wear of the upper guide rail 120.

[0042] In some preferred embodiments, two hanging plates 130 are provided at the edge of the bottom plate 230. The two hanging plates 130 are arranged oppositely, and the base 100 is arranged between the two hanging plates 130.

[0043] Therefore, in this embodiment, by providing two opposite hanging plates 130 such that the base 100 is located between the two hanging plates 130, the contact surface between the translation base 110 and the base 100 can be included, reducing the chance of foreign objects entering. Thus, the wear of the upper guide rail 120 is reduced, ensuring the stable movement of the translation base 110, reducing shaking, and further ensuring that the grinding wheel can grind the product evenly and guaranteeing the product quality.

[0044] In some preferred embodiments, it can be connected to the hanging plate 130 by bolts, thereby simplifying the installation. In particular, the hanging plate 130 can be assembled after the assembly of the bottom plate 230, the upper guide rail 120, and the base 100, which is extremely convenient.

[0045] Refer to Figure 2 and Figure 3 , in this embodiment, a side guide rail 140 is provided between the hanging plate 130 and the base 100, and the side guide rail 140 is arranged parallel to the upper guide rail 120.

[0046] Obviously, in this embodiment, there are two side guide rails 140.

[0047] Therefore, in this embodiment, by providing the side guide rail 140, the clearance change between the base 100 and the translation base 110 in the vertical direction is restricted, and at the same time, the clearance change between the base 100 and the translation base 110 in the horizontal direction is restricted, improving the accuracy of the movement of the translation base 110 and enabling the grinding machine to grind precisely.

[0048] In addition, in this embodiment, the two side guide rails 140 and the upper guide rail 120 form three-sided positioning and limiting, which can reduce or even avoid the yaw of the translation base 110 perpendicular to its moving direction, reduce vibration, reduce the movement during the grinding process, and improve the grinding quality.

[0049] In some preferred embodiments, a first groove 150 may be provided on the side surface of the base 100. The first groove 150 accommodates the side guide rail 140, and the bottom of the first groove 150 is open.

[0050] Therefore, by using the first groove 150 to form a space for installing the side guide rail 140, the distance between the two lower suspension plates 130 can be reduced, the occupied space can be reduced, and at the same time, the thickness of the lower suspension plates 130 is not reduced, and the strength is not affected.

[0051] At the same time, since the bottom of the first groove 150 is open, the machining angle can be selected as needed to avoid interference between the machined fillet and the side guide rail 140.

[0052] Moreover, since the bottom of the first groove 150 is open, the reference plane at the bottom of the base 100 can be reduced, the machining amount can be reduced, the machining cost can be lowered, and the accuracy of the reference plane can also be improved.

[0053] In some preferred embodiments, a first boss 160 may be provided on one side of the base 100. The first boss 160 is connected to the side guide rail 140.

[0054] Therefore, the spaces on both sides of the first boss 160 form an avoidance, no interference will occur, and it is also convenient to machine the first boss 160. In particular, the area of the reference plane for installing the side guide rail 140 on the first boss 160 is reduced, and the machining cost is lowered.

[0055] In some preferred embodiments, a second groove 170 may be provided on the side surface of the base 100. The first boss 160 is provided at the bottom of the second groove 170. The second groove 170 has an upper side surface 180, and the upper side surface 180 abuts and positions against the top of the side guide rail 140.

[0056] That is to say, by arranging the first boss 160 within the area surrounded by the second groove 170, the distance between the two lower suspension plates 130 can be reduced. At the same time, the upper side surface 180 of the second groove 170 abuts and positions against the top of the side guide rail 140, which can simplify the installation and improve the assembly accuracy.

[0057] In some preferred embodiments, the second groove 170 may have a lower side surface 190, and the lower side surface 190 is inclined. A top block 200 is wedge-connected to the lower side surface 190, and the top block 200 jacks up the side guide rail 140 towards the upper side surface 180.

[0058] That is, by using bolts, the top block 200 is locked to the bottom of the second groove 170. During the locking process, the top block 200 will move along the lower side 190. Furthermore, the top block 200 will move upward simultaneously. Then, the top block 200 will lift the side guide rail 140 upward, so that the side guide rail 140 remains in contact with the upper side 180. Finally, when the side guide rail 140 is fixed, the side guide rail 140 remains in contact with the upper side 180.

[0059] Similarly, the upper guide rail 120 and the base 100, as well as the upper guide rail 120 and the bottom plate 230, are also installed using a similar structure.

[0060] The lower suspension plate 130 and the side guide rail 140 are directly connected by bolts, which will not affect the positioning accuracy and will not cause movement jamming.

[0061] At the same time, in some preferred embodiments, the base 100 can include a seat body 270 and a base plate 280. The seat body 270 is connected to the translation seat 110, and the base plate 280 is disposed at the bottom of the seat body 270.

[0062] Therefore, the seat body 270 is made of structural steel to ensure the reliability of the installation reference surface and make the grinding machine durable.

[0063] The base plate 280 can be made of materials such as cast iron to actively absorb vibration energy. At the same time, the manufacturing cost is reduced.

[0064] To prevent external dust and foreign objects from entering, the lower suspension plate 130 can be provided with a lower guard plate 290. The lower guard plate 290 is provided with a hem 300, and the base plate 280 is provided with a side groove 310 for accommodating the hem 300.

[0065] Therefore, the hem 300 is stuck in the side groove 310, which can form a barrier, so that the side guide rail 140 and the upper guide rail 120 are away from debris and the service life is extended.

[0066] Refer to Figure 2 、 Figure 3 and Figure 4 , this embodiment also provides a locking mechanism, which relates to the base 100 and the translation seat 110.

[0067] Specifically, a locking component 340 is provided between the base 100 and the translation seat 110. The locking component 340 includes an inflatable member 350 and a pressing block 360. The inflatable member 350 abuts against the pressing block 360. The inflatable member 350 drives the pressing block 360 to move. The pressing block 360 abuts against the base 100 or the translation seat 110. The inflatable member 350 and the pressing block 360 cooperate to fix the translation seat 110 to the base 100.

[0068] The inflatable member 350 can expand after inflation. And when inflating, a one-way valve can be connected to prevent gas leakage. Thus, the inflatable member 350 can maintain its inflated state, and further, the inflatable member 350 continuously presses the pressing block 360.

[0069] Referring to Figure 2 As shown, in some preferred embodiments, the inflatable member 350 and the pressing block 360 can be arranged on one side of the base 100 in the horizontal direction.

[0070] Therefore, the locking component 340 of the locking mechanism can be avoided from being arranged in the up-and-down direction, without increasing the height of the grinding machine and without affecting the stability of the grinding machine.

[0071] In some preferred embodiments, the inflatable member 350 and the pressing block 360 can be in a long strip shape, and the length directions of the inflatable member 350 and the pressing block 360 are arranged along the moving direction of the translation seat 110.

[0072] Therefore, the length of the locking component 340 in the moving direction of the translation seat 110 is increased, making it difficult for the pressing block 360 to flip. Further, it is ensured that the pressing block 360 can stably contact the translation seat 110 or the base 100.

[0073] In some preferred embodiments, the inflatable member 350 and the pressing block 360 are arranged between the lower suspension plate 130 and the base 100.

[0074] Therefore, it is convenient to install the inflatable member 350 and the pressing block 360, and it is convenient for inspection and maintenance.

[0075] In some preferred embodiments, the lower suspension plate 130 can be provided with a stepped hole 370. The large end of the stepped hole 370 is arranged on the side of the lower suspension plate 130 away from the base 100. The pressing block 360 and the inflatable member 350 are installed in the stepped hole 370, and the inflatable member 350 is located on the side of the pressing block 360 away from the base 100.

[0076] Therefore, it does not occupy the internal space of the base 100, is convenient for layout. Moreover, by providing the stepped hole 370, the pressing block 360 can be limited to prevent the pressing block 360 from flipping.

[0077] In some preferred embodiments, it can further include a half pipe 380 for accommodating the inflatable member 350. The half pipe 380 is arranged on the side of the inflatable member 350 away from the pressing block 360.

[0078] Therefore, the area in contact with the inflatable member 350 is increased, which not only meets the installation requirements but also protects the inflatable member 350 and avoids the inflatable member 350 from being broken.

[0079] In some preferred embodiments, it can further include a mounting strip 390 extending along the outer surface of the half pipe 380. The mounting strip 390 extends along the circumferential direction of the half pipe 380, and both ends of the mounting strip 390 are fixed to the lower suspension plate 130.

[0080] Therefore, the installation strip 390 and the half pipe 380 cooperate to limit the inflatable member 350 at the stepped hole 370, ensuring the continuous effectiveness of the locking assembly 340.

[0081] In some preferred embodiments, the inflatable member 350 and the pressure block 360 can be arranged above the side guide rail 140.

[0082] Therefore, the side guide rail 140 can limit the hanging plate 130 to prevent the hanging plate 130 from moving away from the base 100.

[0083] In this embodiment, by setting the locking assembly 340 with the pressure block 360, when the reaction force of grinding causes a relative movement tendency between the translation seat 110 and the base 100, the pressure block 360 squeezes the base 100 or the translation seat 110, generating a frictional force between the pressure block 360 and the base 100 or the translation seat 110. Further, it prevents the relative movement between the translation seat 110 and the base 100. Therefore, it can firmly lock the translation seat 110, reduce or even avoid the shaking of the translation seat 110, and avoid damage to the screw assembly 220. It not only ensures the accurate movement of the translation seat 110 but also guarantees the grinding quality.

[0084] Meanwhile, in this embodiment, by setting the inflatable member 350 to drive the pressure block 360 to generate extrusion, the pressure block 360 is evenly pressed, ensuring sufficient and more uniform extrusion force by making the pressure block 360 fully contact the base 100 or the translation seat 110. Further, it increases the frictional force, making the translation seat 110 and the base 100 more firmly locked together, further protecting the screw assembly 220 and further improving the grinding quality.

[0085] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
