[0021] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0022] The present application provides an oilstone dry cutting machine, comprising: a machine platform 10, on which an oilstone position is provided, the oilstone position being used to fix the oilstone to be cut; a tool 21, which is provided on the machine platform 10 and is used to cut the oilstone; a cutting drive assembly 30, which is used to drive the tool 21 and the oilstone on the oilstone position to approach or move away from each other; when the tool 21 approaches the oilstone on the oilstone position, the tool 21 can act on the oilstone to achieve cutting; when the tool 21 moves away from the oilstone on the oilstone position, the oilstone can be displaced, or a new oilstone to be cut can enter the oilstone position.

[0023] The machine 10 may be any table, cabinet or the like, which is convenient for arranging cutting components such as the cutting tool 21 and is convenient for workers to operate.

[0024] The oilstone position can be any structure such as a frame or a groove to conveniently accommodate and fix the oilstone, and the oilstone position is open on one side facing the tool 21; during dry cutting, the tool 21 can pass through the open side of the oilstone position, extend into the oilstone position, and contact the oilstone.

[0025] It is easy to understand that by setting the oilstone position, the cutting position of the oilstone is determined and unified to facilitate the rapid loading and accurate cutting of the oilstone, and the cutting state of the oilstone can be calibrated and limited to facilitate the tool 21 to act accurately on the oilstone, thereby improving the dry cutting efficiency and rough processing yield of the oilstone.

[0026] The cutter 21 may be a cutting structure of any configuration, such as a long strip blade, an angled blade, or a utility blade, or a cutting structure of any blade shape, such as a flat blade or a serrated blade.

[0027] The cutter 21 is arranged opposite to the oilstone position. After the oilstone is in place, the cutter 21 and the oilstone are brought close to each other by the cutting drive assembly 30, and the cutter 21 can cut the oilstone and cut out the oilstone block of the required size. After completing a dry cutting, the cutter 21 and the oilstone are moved away from each other by the cutting drive assembly 30, and the worker or unloading equipment (such as a manipulator, robot, etc.) can take away the oilstone block or put a new oilstone to be cut into the oilstone position.

[0028] In one embodiment, the level of the oilstone is fixed, and the cutting drive assembly 30 is used to drive the cutter 21 to approach or move away from the oilstone level.

[0029] In another embodiment, the cutter 21 is fixed, and the cutting drive assembly 30 is used to drive the oilstone level to approach or move away from the oilstone level. In this embodiment, the oilstone level is also used as a mobile carrier, and the oilstone level is slidably arranged on the machine table 10 and can move with the oilstone under the drive of the cutting drive assembly 30.

[0030] The cutting drive assembly 30 may be a drive member such as a pneumatic cylinder or an electric cylinder.

[0031] In another embodiment, the cutting drive assembly 30 includes: a first horizontal direction drive member 31 and a second horizontal direction drive member 32, the first horizontal direction drive member 31 is used to drive the tool 21 to move along the first horizontal direction so that the tool 21 can approach the cutting whetstone, and the second horizontal direction drive member 32 is used to drive the tool 21 to move along the second horizontal direction so that the tool 21 can face different parts of the whetstone.

[0032] For details, please refer to Figure 1 In the illustrated embodiment, the first horizontal direction is the up-down direction, and the second horizontal direction is the left-right direction. At the same time, the first horizontal direction can be regarded as the width direction of the oilstone, and the second horizontal direction can be regarded as the length direction of the oilstone. The tool 21 is arranged at the movable end of the first horizontal direction driving member 31, and the first horizontal direction driving member 31 is arranged at the movable end of the second horizontal direction driving member 32. The oilstone material level is located directly below the tool 21.

[0033] Continue to refer to Figure 1 , assuming that the length of the oilstone is L1 and the width is L2, the length of the required oilstone block is L2 and the width is L3, and L3<½L1; at this time, one oilstone can cut at least two oilstone blocks. Specifically, the oilstone to be cut is placed in the oilstone position so that the oilstone extends in the left-right direction; the tool 21 is moved to the first cutting position by the second horizontal driving member 32, and the tool 21 is made close to the oilstone in cooperation with the first horizontal driving member 31 to complete the first cutting, and the first oilstone block with a width of L3 is cut out at the left end of the oilstone; the tool 21 is retracted to the avoidance position by the first horizontal driving member 31, and the tool 21 is driven to move a distance L3 to the right by the second horizontal driving member 32, and the tool 21 reaches the second cutting position, and the tool 21 is made close to the oilstone in cooperation with the first horizontal driving member 31 again to complete the second cutting, and the second oilstone block with a width of L3 is cut out... and so on, the cutting of the entire oilstone is completed until the width of the remaining part of the right end of the oilstone is no more than L3.

[0034] The first horizontal direction driving member 31 and the second horizontal direction driving member 32 may be driving components such as a cylinder or an electric cylinder.

[0035] In this embodiment, the oil stone position can use the table top of the machine 10 to receive the oil stone, or can have an independent loading surface for receiving the oil stone.

[0036] In another embodiment, the cutting drive assembly 30 includes: a first horizontal direction drive member 31 and a second horizontal direction drive member 32, the first horizontal direction drive member 31 is used to drive the oilstone level to move along the first horizontal direction so that the oilstone is close to the tool 21 to achieve cutting, and the second horizontal direction drive member 32 is used to drive the oilstone level to move along the second horizontal direction so that different parts of the oilstone face the tool 21.

[0037] For details, please refer to Figure 2 In the illustrated embodiment, the first horizontal direction is the up-down direction, and the second horizontal direction is the left-right direction. At the same time, the first horizontal direction can be regarded as the width direction of the oilstone, and the second horizontal direction can be regarded as the length direction of the oilstone. The oilstone position has an independent load surface, and the oilstone position is arranged at the movable end of the first horizontal direction driving member 31, and the first horizontal direction driving member 31 is arranged at the movable end of the second horizontal direction driving member 32. The tool 21 is arranged directly above the oilstone position. Similarly, after completing a cutting, the first horizontal direction driving member 31 and the second horizontal direction driving member 32 cooperate to drive the oilstone position and the oilstone to move left and right, so that the tool 21 is aligned with different positions of the oilstone, thereby realizing multi-segment cutting of the oilstone.

[0038] The tool 21 or the oilstone material position is translated by the first horizontal driving member 31 and the second horizontal driving member 32. When the oilstone is cut into multiple sections, it is not necessary to remove the cut oilstone block after one cutting is completed. Continuous cutting can be performed by displacement until the entire oilstone is cut.

[0039] Optionally, the cutter 21 is a circular blade.

[0040] The circular blade has many cutting edges. If one edge is worn out due to long-term use, the tool 21 can be rotated to adjust another edge to face the oilstone for cutting, thereby increasing the service life of the tool 21.

[0041] Furthermore, the whetstone dry cutting machine provided in the present application also includes a rotary driving member 22, and the rotary driving member 22 is used to drive the tool 21 to rotate so that the tool 21 can cut the whetstone.

[0042] The rotary drive member 22 may be a rotary cylinder, a motor or other rotary drive member.

[0043] The tool 21 can be rotated by the rotating driving member 22. During the dry cutting process, the tool 21 acts on the oil stone in a rotating posture, which can not only enhance the cutting force and accelerate the oil stone cutting through the high-speed rotation of the blade end, but also avoid the continuous work of the blade end at a single position, thereby improving the overall service life and stability of the tool 21.

[0044] Optionally, a support plate 23 is provided on the whetstone position, and the support plate 23 is used to support the side of the whetstone away from the tool 21 ; during the cutting process, the whetstone is pressed between the support plate 23 and the tool 21 .

[0045] The support plate 23 has a limiting function, which can not only limit the position of the oil stone, but also prevent the oil stone from moving away from the tool 21 due to force during the cutting process, thereby ensuring that the tool 21 can cut the oil stone.

[0046] It is easy to understand that when the cutter 21 cuts the oilstone, it will inevitably cut the support plate 23. Therefore, the support plate 23 can be made of a material with high strength, wear resistance and pressure resistance.

[0047] Optionally, the support plate 23 is detachably disposed on the platform 10 .

[0048] For example, the support plate 23 is fastened to the machine platform 10 by screws; the support plate 23 can be removed by unscrewing the screws, and the support plate 23 can be fixed again by screwing the screws in.

[0049] For another example, the support plate 23 is attached to the machine table 10 by magnetic adsorption (e.g., one of the support plate 23 and the machine table 10 is made of metal material, and the other is provided with a magnet or an electromagnet); the support plate 23 can be fixed by magnetic adsorption, and the support plate 23 can be removed by overcoming the magnetic attraction.

[0050] For another example, one of the support plate 23 and the machine 10 is provided with an insert block, and the other is provided with a socket, so that the insert block is inserted into the socket to fix the support plate 23; the support plate 23 can be removed by disengaging the insert block from the socket.

[0051] The present application does not limit the specific installation method of the support plate 23 .

[0052] The support plate 23 is detachably arranged on the machine table 10 . When the support plate 23 is damaged by the tool 21 and the constraint on the oilstone is affected, the old support plate 23 can be removed and replaced with a new one conveniently.

[0053] Optionally, the cutting drive assembly 30 is used to drive the support plate 23 to move closer to or away from the tool 21 ; during the dry cutting process, the cutting drive assembly 30 can drive the support plate 23 to push the whetstone so that the whetstone moves closer to the tool 21 .

[0054] For details, please refer to Figure 3 In the illustrated embodiment, the cutting drive assembly 30 adopts a cylinder; a slide groove 11 is provided on the machine table 10, and the slide groove 11 extends in the up and down directions. The upper end of the slide groove 11 is connected to the tool 21; the slide groove 11 is the oilstone material position, and the groove width of the slide groove 11 is adapted to the length of the oilstone, and the oilstone can be stuck in the slide groove 11.

[0055] Continue to refer to Figure 3 The support plate 23 is slidably disposed in the chute 11 and is connected to the movable end of the cutting drive assembly 30. After the oilstone to be cut is placed in the chute 11, the cutting drive assembly 30 drives the support plate 23 to move from bottom to top along the chute 11, and the support plate 23 can push the oilstone toward the tool, thereby achieving cutting.

[0056] Optionally, the support plate 23 is made of elastic material.

[0057] For example, the support plate 23 can be made of rubber, plastic, etc.

[0058] By making the support plate 23 made of elastic material, the support plate 23 has certain elastic properties. During the dry cutting process, the tool 21 acts on the oilstone and can press the oilstone against the support plate 23. After the support plate 23 is subjected to force, there will be a certain deformation. On the one hand, it can prevent the tool 21 from directly and rigidly hitting the oilstone and causing instability in the part where the oilstone is preferentially subjected to force. On the other hand, the elastic force of the deformed support plate 23 can act in the opposite direction on the oilstone, thereby increasing the pressure between the oilstone and the tool 21.

[0059] Optionally, the oilstone dry cutting machine further comprises a rotary driving member 22, and the rotary driving member 22 is used to drive the cutter 21 to reciprocate.

[0060] Specifically, the cutter 21 is a circular blade, and the rotary drive 22 drives the cutter 21 to reciprocate, so as to achieve reciprocating cutting. At this time, the cutter 21 does not rotate in circles, but vibrates at a high frequency and with a small amplitude. Since the oilstone is a rigid structure, the cutter 21 can cut the oilstone by vibrating; but since the support plate 23 is made of elastic material and has a tough structure, the cutter 21 vibrates without damaging the support plate 23.

[0061] Furthermore, the blade end of the tool 21 is configured to be serrated, which can enhance the cutting effect of the tool 21 on the oilstone.

[0062] Optionally, an adjustment fixture is provided on the oilstone position, and the adjustment fixture is used to clamp the oilstone.

[0063] Specifically, when the adjustment fixture clamps the two ends of the oilstone in the length direction, the tool 21 can cut out an oilstone block with the original oilstone width; when the adjustment fixture clamps the two ends of the oilstone in the width direction, the tool 21 can cut out an oilstone block with the original oilstone length.

[0064] By adjusting the fixture to clamp the oilstone, the oilstone can be reliably fixed to prevent the oilstone from shifting or moving during the dry cutting process.

[0065] In one embodiment, the adjustment fixture includes two clamping plates and a pneumatic finger, and the pneumatic finger can drive the two clamping plates to move closer to each other to clamp the oilstone, or drive the two clamping plates to move away from each other to loosen the oilstone.

[0066] In this embodiment, the output stroke of the pneumatic fingers is changed and the clamp is adjusted so that oilstones of different lengths or widths can be clamped.

[0067] In another embodiment, the adjustment fixture includes: a fixed plate 41, which is fixedly set on the oilstone level; a movable plate 42, which is slidably set on the oilstone level and is arranged opposite to the fixed plate 41, and the cutting direction of the tool 21 is perpendicular to the arrangement direction of the fixed plate 41 and the movable plate 42; wherein the movable plate 42 can be close to or away from the fixed plate 41, so as to facilitate the adjustment of the fixture to clamp oilstones of different sizes.

[0068] For details, please refer to Figure 4 In the illustrated embodiment, the fixed plate 41 and the movable plate 42 are spaced apart in the left-right direction, and the cutter 21 is disposed above the fixed plate 41 and the movable plate 42. The fixed plate 41 cannot move in the left-right direction; the movable plate 42 can approach or move away from the fixed plate 41 in the left-right direction. At this time, the fixed plate 41 can be used as a reference plate for positioning the oilstone, ensuring that one end of the oilstone abuts against the fixed plate 41. When the movable plate 42 abuts against the other end of the oilstone so that the oilstone is clamped between the fixed plate 41 and the movable plate 42, the end of the oilstone abutting against the fixed plate 41 must be determined and unified, so that the cutter 21 can confirm the cutting position.

[0069] In a specific embodiment, the tool 21 cuts the oilstone into multiple sections; after completing one cut, the cut oilstone block is removed, so that the remaining oilstone is clamped by the fixed plate 41 and the movable plate 42 again. Since the relative position of the tool 21 and the fixed plate 41 remains unchanged, the tool 21 can accurately cut the required oilstone block.

[0070] In order to facilitate the movable plate 42 to approach or move away from the fixed plate 41, in one embodiment, the adjustment fixture further includes an adjustment drive member, which can be a driving structure such as a cylinder or an electric cylinder. The adjustment drive member is connected to the movable plate 42 and can drive the movable plate 42 to approach or move away from the fixed plate 41. Before clamping the oilstone, the fixed plate 41 and the movable plate 42 are moved away from each other. After the oilstone is placed, the movable plate 42 is driven by the adjustment drive member to approach the fixed plate 41 until the oilstone is clamped between the fixed plate 41 and the movable plate 42. By changing the output stroke of the adjustment drive member, the adjustment fixture can be conveniently adjusted to clamp oilstones of different widths or lengths.

[0071] In another embodiment, referring to Figure 4 The adjustment fixture also includes an elastic member 43, which can be made of an elastic material or an elastic structure such as a spring or a spring sheet. One end of the elastic member 43 is fixedly arranged (connected to the machine table 10, or connected to the fixed plate 41), and the other end is connected to the movable plate 42; the movable plate 42 is moved away from the fixed plate 41, and the elastic member 43 is deformed; after the oilstone is inserted, the force applied to the movable plate 42 is removed, the elastic member 43 is restored, and can actively drive the movable plate 42 to reset and approach the fixed plate 41 to clamp the oilstone; the presence of the oilstone makes it impossible for the elastic member 43 to fully restore, and the elastic force generated by the deformation of the elastic member 43 acts in the opposite direction on the movable plate 42, so that the movable plate 42 can be pressed against the oilstone.

[0072] In this embodiment, as long as the elastic member 43 is within the deformation range and the movable plate 42 is within the movement range, the movable plate 42 can press the oilstones of different widths or lengths against the fixed plate 41 by relying on the elastic deformation characteristics of the elastic member 43 itself.

[0073] In a specific embodiment, referring to Figure 4 The oilstone material position includes a carrier plate 12, which is used to hold the oilstone; a slide rail is provided on the machine table 10, which extends in the up-down direction, and the carrier plate 12 is slidably provided on the slide rail; the cutting drive assembly 30 is connected to the carrier plate 12 and can drive the carrier plate 12 to move in the up-down direction along the slide rail; the fixed plate 41 is fixedly provided on the carrier plate 12, and the movable plate 42 is provided on the right side of the fixed plate 41; a mounting plate 13 is provided on the carrier plate 12 and on the right side of the movable plate 42, and one end of the elastic member 43 is connected to the movable plate 42, and the other end is connected to the mounting plate 13. When no oil stone is inserted, the elastic member 43 is stretched and the movable plate 42 is close to the fixed plate 41; force is applied to the movable plate 42 to make it move away from the fixed plate 41, and the oil stone can be inserted between the two. At this time, the elastic member 43 is compressed; the force is removed from the movable plate 42, and the elastic member 43 rebounds, which will push the movable plate 42 close to the fixed plate 41; until the movable plate 42 presses the oil stone against the fixed plate 41, the elastic member 43 is still in a compressed state, and the elastic force generated by its deformation can act in the opposite direction on the movable plate 42, so that the movable plate 42 remains pressed against the oil stone.

[0074] continue Figure 4 , a support plate 23 is also provided on the carrier plate 12, and the support plate 23 is provided below the fixed plate 41 and the movable plate 42. When the oilstone is placed, the lower end of the oilstone is against the support plate 23; after the oilstone is clamped, the left end of the oilstone is ensured to be against the fixed plate 41 and the right end is against the movable plate 42; because the oilstone is a cubic structure, the oilstone can maintain an accurate, uniform and reliable state when the four sides are restricted, thereby ensuring the accuracy and stability of cutting.

[0075] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
