Description

Technical Field

[0001] The utility model relates to the field of leveling devices, in particular to a leveling device used for diamond processing. Background Art

[0002] Leveling devices are often required in the field of diamond processing. Currently commonly used leveling devices can refer to, for example, the leveling device provided by the Chinese invention application "An automatic leveling device for laser forming" with application number CN202311240817.1 (publication number CN117301002A).

[0003] The existing leveling device uses sensors such as position sensors to detect whether the plane of the platform is tilted compared to the reference plane, and then adjusts the local height of the platform through a driving source such as a vertically arranged electric push rod, so as to adjust the plane of the platform to be parallel to the reference plane. However, this type of existing leveling device may have the following defects when used in the diamond processing process: 1. The sensor of the existing leveling device can only detect whether the plane of the platform is tilted compared to the reference plane, but in the diamond processing process, it is sometimes necessary to level the upper surface of the material on the platform, for example, when polishing diamonds, it is sometimes necessary to level the upper surface of the material, so the existing leveling device is not suitable for this situation; 2. The driving source of the existing leveling device is usually set vertically, which makes the leveling device have a certain size height, so some equipment may not have enough space to install the leveling device, for example, refer to the lathe disclosed in the Chinese invention patent "A Diamond Processing Laser Lathe and Processing Technology" with publication number CN114985978A. Therefore, it is necessary to further improve the existing technology. Utility Model Content

[0004] The first technical problem to be solved by the utility model is to provide a leveling device capable of leveling the upper surface of a material on a platform in view of the above-mentioned existing technical status.

[0005] The second technical problem to be solved by the present invention is to provide a leveling device with relatively small size and height in view of the above-mentioned existing technical status.

[0006] The technical solution adopted by the utility model to solve the first technical problem is: the leveling device for diamond processing can be installed in the working space of the working equipment, including:

[0007] A base that can be added to a work platform within the workspace;

[0008] A leveling platform, arranged on the base, comprising a fixing portion fixedly connected to the base, the leveling platform comprising a working plane N for placing an object to be adjusted, the object to be adjusted comprising a plane P to be adjusted;

[0009] An adjustment mechanism, disposed below the leveling platform, capable of adjusting the height of the local working plane N;

[0010] It is characterized by also including:

[0011] A distance measuring mechanism is arranged above the leveling platform, and includes a reference member, wherein the reference member defines a reference plane M. The distance measuring mechanism also includes a distance measuring unit, and the distance measuring unit can move on the reference plane M or a plane parallel to the reference plane M to detect the distance between the detection points of at least three planes P to be adjusted and the reference plane M, so as to determine whether the plane P to be adjusted is parallel to the reference plane M. The distance measuring mechanism is communicatively connected with the adjustment mechanism to adjust the plane P to be adjusted to be parallel to the reference plane M.

[0012] To solve the second technical problem, preferably, the adjustment mechanism includes at least two adjustment members capable of adjusting the distance between the local working plane N and the reference plane M, and the adjustment member includes a driving source and a transmission mechanism, the driving source is horizontally arranged and is in communication connection with the distance measuring mechanism, and the transmission mechanism can change the horizontal force provided by the driving source into a vertical force acting on the leveling platform, thereby adjusting the distance between the local working plane N and the reference plane M. Such a design is made in consideration of the fact that the length of the driving source is usually longer than the width, so the horizontal arrangement of the driving source can reduce the size and height of the leveling device, and the transmission mechanism can be composed of a variety of components such as rods, shafts, gears, and sliders; since three non-collinear points determine a plane, and considering that the leveling platform already includes a fixing portion fixedly connected to the base, the height of the fixing portion is constant, the adjustment mechanism needs to include at least two adjustment members.

[0013] In order to enable the transmission mechanism to change the horizontal force provided by the driving source into a vertical force, preferably, the transmission mechanism includes a first transmission member and a second transmission member, the first transmission member is connected to the driving source, and includes a first body extending away from the driving source along the length direction of the driving source, the first body is provided with a guide rail with an inclination angle α relative to the reference plane M, and the second transmission member can move along the guide rail when the first body approaches or moves away from the driving source. The first transmission member is connected to the driving source, so when the driving source outputs horizontal power, the first body is driven by the driving source to approach or move away from the driving source along the length direction of the driving source, and the second transmission member will move along the guide rail at this time. Since the guide rail is inclined at an inclination angle α relative to the reference plane M, the second transmission member is actually approaching or moving away from the leveling platform during the movement along the guide rail, so that the second transmission member can act on the leveling platform to adjust the distance between the local working plane N and the reference plane M, so as to adjust the plane P to be adjusted to be parallel to the reference plane M.

[0014] Furthermore, in order to enable the second transmission member to slide along the guide rail and act on the leveling platform, preferably, the second transmission member includes a moving part that can move along the guide rail, the moving part extends to both sides along the length direction of the guide rail to form a second body, and the second body is partially protruded to form an adjustment part that contacts the leveling platform. According to actual needs, the moving part can have different structures to adapt to guide rails of different structures, and the adjustment part is a component that actually contacts the leveling platform. The adjustment part can be a structure such as a boss, so as to conflict with the leveling platform to act on the leveling platform.

[0015] In order to make the first transmission member only approach or move away from the driving source along the length direction of the driving source, preferably, the transmission mechanism also includes a first limiter for limiting the first transmission member, the first limiter is fixedly connected to the base and is arranged on both sides of the width direction of the first body, the first limiter contacts the first body toward the inner wall of the first body, the first body extends toward the first limiter to form a limit step, and the lower wall surface of the first limiter contacts the limit step. With such a design, the first transmission member can only approach or move away from the driving source along the length direction of the driving source, thereby reducing the error of the transmission mechanism and making the transmission mechanism run relatively stably and efficiently.

[0016] In order to prevent the second transmission member from moving closer to or farther from the driving source along the length direction of the driving source together with the first transmission member, preferably, the transmission mechanism also includes a second limit member, the second limit member is arranged above the first limit member and is fixedly connected to the first limit member, the second limit member is arranged on both sides of the length direction of the second body, and the second limit member contacts the second body toward the inner wall of the second body, thereby limiting the movement of the second transmission member along the length direction of the first body. If the second limit member is not provided, when the driving source drives the first transmission member to move closer to or farther from the driving source along the length direction of the driving source, the second transmission member will follow the first transmission member to move closer to or farther from the driving source along the length direction of the driving source, and will not move along the guide rail of the first transmission member. In this case, the second transmission member cannot play an adjusting role on the leveling platform, so it is necessary to provide the second limit member to prevent the second transmission member from moving closer to or farther from the driving source along the length direction of the driving source together with the first transmission member.

[0017] In order to enable the leveling platform to have a fixed portion with a constant height, preferably, a fixing member for fixing a part of the leveling platform is provided on the base, and the fixing member is fixedly connected to the leveling platform to form the fixed portion of the leveling platform. The base is also provided with a support member for supporting the leveling platform, and the support member and the fixing portion are centrally symmetrical about the symmetry center of the base. The fixing member can be a bolt or other component, and the fixing portion is fixedly connected to the base through the fixing member so that the height of the fixing portion remains constant. It is obviously not enough to rely on only one fulcrum of the fixing member to keep the leveling platform in a relatively stable state, so a support member needs to be provided. In fact, the support member can be provided at other positions, but the centrally symmetrical arrangement of the support member and the fixing member about the symmetry center of the base can make the leveling platform relatively stable.

[0018] Furthermore, in order to support the leveling platform, preferably, the leveling platform is provided with a through hole for the support member to pass through, at least three elastic members are evenly distributed along the length direction of the support member, the leveling platform is provided with a guide groove capable of at least partially accommodating each of the elastic members, and a limit cover fixedly connected to the leveling platform is also provided above each of the elastic members, the limit cover and the guide groove jointly limit each of the elastic members, and each of the elastic members makes the leveling platform always have a tendency to move away from the support member. With such a design, at least three forces from the leveling platform are evenly distributed on the periphery of the support member, so that the forces of the support member and the leveling platform are in a balanced state, thereby satisfying the need for the support member to support the leveling platform. In addition, since the support member and the elastic member are used for support, the support structure has a certain flexibility, and the influence on the adjustment platform being locally close to or away from the base is relatively small.

[0019] In order to make the leveling platform always have a tendency to approach the base, preferably, the base is provided with a first magnetic attraction portion and a second magnetic attraction portion, and the first magnetic attraction portion and the second magnetic attraction portion are respectively arranged on both sides of the upper surface of the base, and correspondingly, the leveling platform is provided with a first matching portion and a second matching portion respectively attracted by the first magnetic attraction portion and the second magnetic attraction portion. The first magnetic attraction portion can attract the first matching portion, and the second magnetic attraction portion can attract the second matching portion, and the first magnetic attraction portion and the second magnetic attraction portion are arranged on both sides of the upper surface of the base, so that the leveling platform always has a tendency to approach the base, so that when the adjustment portion is away from the leveling platform, the corresponding part of the leveling platform can approach the base under the action of the attraction. In addition, according to actual needs, the connection between the first magnetic attraction portion and the second magnetic attraction portion and the first matching portion and the second matching portion can actually be replaced by other flexible connection methods such as elastic parts.

[0020] In order to enable the distance measuring part to move on the reference plane M or a plane parallel to the reference plane M, preferably, a first moving part that can move along the X direction and a second moving part that can move along the Y direction are provided on the reference plane M, the first moving part is staggered below the second moving part and moves with the second moving part, and the distance measuring part is fixedly connected to the first moving part. It should be noted that the reference part defined by the reference plane M does not necessarily have to be an actual physical part. For example, the reference plane M can be a plane formed by the common moving range of the first moving part and the second moving part. In this case, the first moving part and the second moving part are the reference parts.

[0021] Compared with the prior art, the advantages of the utility model are:

[0022] 1. The distance measuring mechanism arranged above the leveling platform can determine whether the plane P to be adjusted of the object to be adjusted is parallel to the reference plane M, so that the adjustment mechanism can be driven to adjust the plane P to be adjusted to be parallel to the reference plane M, thereby meeting the requirement of leveling the upper surface of the material on the platform;

[0023] 2. By setting the driving source horizontally and using a transmission mechanism to change the horizontal force provided by the driving source into a vertical force acting on the leveling platform, the overall height of the leveling device is relatively low, which is conducive to installation in equipment with a low working space height.

[0035] The present invention is further described in detail below in conjunction with specific embodiments.

[0036] like Figures 1 to 8As shown, it is a preferred embodiment of the utility model. The leveling device for diamond processing in this embodiment can be installed in the working space 11 of the working equipment 1. The leveling device includes a base 2 that can be installed on the working platform 12 in the working space 11, and a leveling platform 3 is arranged on the base 2. The leveling platform 3 includes a fixing part 31 fixedly connected to the base 2 and a working plane N for carrying an object 13 to be adjusted, and the object 13 to be adjusted includes a plane P to be adjusted. An adjustment mechanism 4 capable of adjusting the height of the local working plane is arranged below the leveling platform 3. The leveling device also includes a distance measuring mechanism 5 arranged above the leveling platform 3, the distance measuring mechanism 5 includes a reference part 51, the reference part 51 defines a reference plane M, and the distance measuring mechanism 5 also includes a distance measuring part 52, which can move on the reference plane M or a plane parallel to the reference plane M to detect the distance between the detection point positions of at least three planes P to be adjusted and the reference plane M, so as to determine whether the plane P to be adjusted is parallel to the reference plane M. Furthermore, the distance measuring mechanism 5 is connected to the adjusting mechanism 4 in communication, so as to adjust the plane P to be adjusted to be parallel to the reference plane M through the adjusting mechanism 4. Figure 1 The reference member 51 in this embodiment is a reference platform installed on the upper part of the working device 1. A first moving part 53 that can move along the X direction and a second moving part 54 that can move along the Y direction are arranged on the reference plane M defined by the reference member 51. The first moving part 53 is staggered below the second moving part 54 and moves with the second moving part 54. The distance measuring part 52 is fixedly connected to the first moving part 53, so that the distance measuring part 52 can move on a plane parallel to the reference plane M to detect the points to be detected on the plane to be detected P. Considering that three non-collinear points determine a plane, at least three points to be detected on the plane to be detected P detected by the distance measuring part 52 should not be on a straight line.

[0037] See also Figure 3In this embodiment, the adjustment mechanism 4 includes at least two adjustment members 41 capable of adjusting the distance between the local working plane N and the reference plane M. The adjustment member 41 includes a driving source 42 and a transmission mechanism 43. The driving source 42 is arranged horizontally and is in communication with the distance measuring mechanism 5. The transmission mechanism 43 can change the horizontal force provided by the driving source 42 into a vertical force acting on the leveling platform 3, thereby adjusting the distance between the local working plane N and the reference plane M. Since three non-collinear points determine a plane, considering that the leveling platform 3 already includes a fixing portion 31 fixedly connected to the base 2, and the height of the fixing portion 31 is constant, it is necessary for the adjustment mechanism 4 to include at least two adjustment members 41. In this embodiment, the adjustment mechanism 4 includes two adjustment members 41. On the other hand, the driving source 42 is arranged horizontally because the length of the driving source 42 is usually longer than the width, so the driving source 42 is arranged horizontally to reduce the size and height of the leveling device. Furthermore, in order to enable the transmission mechanism 43 to change the horizontal force provided by the driving source 42 into a vertical force, the transmission mechanism 43 in this embodiment includes a first transmission member 44 and a second transmission member 45. The first transmission member 44 is connected to the driving source 42 and includes a first body 441 extending away from the driving source 42 along the length direction of the driving source 42. Figure 6 , a guide rail 442 with an inclination angle α relative to the reference plane M is provided on the first body 441, and the second transmission member 45 can move along the guide rail 442 when the first body 441 approaches or moves away from the driving source 42. Since the guide rail 442 is in an inclined state with an inclination angle α relative to the reference plane M, the second transmission member 45 is actually approaching or moving away from the leveling platform 3 during the process of moving along the guide rail 442, so that the second transmission member 45 can act on the leveling platform 3 to adjust the distance between the local working plane N and the reference plane M, thereby adjusting the plane P to be adjusted to be parallel to the reference plane M. The second transmission member 45 in this embodiment includes a moving part 452 that can move along the guide rail 442, and the moving part 452 extends to both sides along the length direction of the guide rail 442 to form a second body 451, and a local protrusion on the second body 451 forms an adjusting part 453 that contacts the leveling platform 3. The adjusting part 453 is a component that actually contacts the leveling platform 3, so that it conflicts with the leveling platform 3 to act on the leveling platform 3.

[0038] In order to make the first transmission member 44 only approach or move away from the driving source 42 along the length direction of the driving source 42, the transmission mechanism 43 in this embodiment also includes a first limiting member 47 for limiting the first transmission member 44. The first limiting member 47 is fixedly connected to the base 2 and is arranged on both sides of the width direction of the first body 441. The first limiting member 47 contacts the first body 441 toward the inner wall of the first body 441, and the first body 441 extends toward the first limiting member 47 to form a limiting step 443. The lower wall surface of the first limiting member 47 contacts the limiting step 443 to complete the limiting of the first transmission member 44. Furthermore, in order to prevent the second transmission member 45 from approaching or moving away from the driving source 42 along the length direction of the driving source 42 together with the first transmission member 44, the transmission mechanism 43 in this embodiment also includes a second limiting member 48, which is arranged above the first limiting member 47 and fixedly connected to the first limiting member 47, and the second limiting member 48 is arranged on both sides of the length direction of the second body 451, and the second limiting member 48 contacts the second body 451 toward the inner wall of the second body 451, thereby limiting the movement of the second transmission member 45 along the length direction of the first body 441. If the second limit member 48 is not set, when the driving source 42 drives the first transmission member 44 to move closer to or away from the driving source 42 along the length direction of the driving source 42, the second transmission member 45 will follow the first transmission member 44 to move closer to or away from the driving source 42 along the length direction of the driving source 42, and will not move along the guide rail 442 of the first transmission member 44. In this case, the second transmission member 45 cannot play an adjusting role on the leveling platform 3. Therefore, the second limit member 48 needs to be set to prevent the second transmission member 45 from moving closer to or away from the driving source 42 along the length direction of the driving source 42 together with the first transmission member 44.

[0039] In order to enable the leveling platform 3 to have a fixed portion 31 of a constant height, a fixing member 21 for fixing a part of the leveling platform 3 is provided on the base 2. The fixing member 21 is fixedly connected to the leveling platform 3 to form the fixed portion 31 of the leveling platform 3. The fixing member 21 in this embodiment is a bolt. Considering the stability of the leveling platform 3, a supporting member 22 for supporting the leveling platform 3 is also provided on the base 2. The supporting member 22 and the fixing member 21 are in a centrally symmetrical relationship about the symmetry center of the base 2. Furthermore, the leveling platform 3 is provided with a through hole 32 for the support member 22 to pass through, at least three elastic members 221 are evenly distributed along the length direction of the support member 22, and the leveling platform 3 is provided with a guide groove 33 capable of at least partially accommodating each elastic member 221. A limit cover 222 fixedly connected to the leveling platform 3 is also provided above each elastic member 221. The limit cover 222 and the guide groove 33 jointly limit each elastic member 221, and each elastic member 221 makes the leveling platform 3 always have a tendency to move away from the support member 22. In this embodiment, four elastic members 221 are provided. Such a design makes four forces from the leveling platform 3 evenly distributed on the periphery of the support member 22, so that the forces of the support member 22 and the leveling platform 3 are in a balanced state, thereby meeting the need for the support member 22 to support the leveling platform 3. In addition, since the support member 22 and the elastic member 221 are used for support, the support structure has a certain flexibility, and the influence on the adjustment platform 3 being locally close to or away from the base 2 is relatively small. In order to make the leveling platform 3 always have a tendency to approach the base 2, the base 2 is provided with a first magnetic attraction portion 23 and a second magnetic attraction portion 24, which are respectively arranged on both sides of the upper surface of the base 2, and correspondingly, the leveling platform 3 is provided with a first matching portion 34 and a second matching portion 35 respectively attracted by the first magnetic attraction portion 23 and the second magnetic attraction portion 24. The first magnetic attraction portion 23 can attract the first matching portion 34, and the second magnetic attraction portion 24 can attract the second matching portion 35, and the first magnetic attraction portion 23 and the second magnetic attraction portion 24 are arranged on both sides of the upper surface of the base 2, so that the leveling platform 3 always has a tendency to approach the base 2, so that when the adjustment portion 453 is away from the leveling platform 3, the corresponding part of the leveling platform 3 can approach the base 2 under the action of the attraction.

[0040] The use process of the leveling device provided in this embodiment is as follows. For the convenience of observation, Fig.10 and Fig.11 The first stopper 47 is hidden:

[0041] like Fig. 9 As shown, at this time, the leveling device is in the initial state, no object 13 to be adjusted is placed on the working plane N, and the distance measuring mechanism 5 does not perform any detection; see Fig.10, the object 13 to be adjusted is placed on the working plane N. Under the action of gravity, the working plane N is tilted relative to the reference plane M. At the same time, the plane P to be adjusted of the object 13 to be adjusted is also tilted relative to the reference plane M along with the working plane N. The leveling device enters a tilted state. At this time, the distance measuring mechanism 5 starts to work, and the distance measuring part 52 moves to the top of the plane P to be adjusted to detect the distances of at least three points to be measured on the plane P to be adjusted relative to the reference plane M, and starts to control the adjustment mechanism 4 to adjust the leveling platform 3; see Fig.11 , the dotted line in the figure is Fig.10 The middle adjusting part 453 is positioned. At this time, under the action of the driving source 42, the first transmission member 44 moves away from the driving source 42 along the length direction of the driving source 42, and the second transmission member 45 moves upward along the guide rail 442. The adjusting part 453 moves vertically upward and acts on the leveling platform 3, and finally the plane P to be leveled is adjusted to a state parallel to the reference plane M.
