[0051] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0052] The following combines Figures 1 to 5 to describe the sliding table mechanism of the embodiments of the present utility model.

[0053] As Figures 1 to 5As shown in the figure, the sliding table mechanism provided by the embodiment of the present utility model includes a base 1, a sliding table 2, a fixing member 3, and an adjusting member 4. The sliding table 2 is slidably connected to the base 1, and the sliding table 2 is provided with a first threaded hole 21. The fixing member 3 is disposed on one side of the base 1, and the fixing member 3 is provided with a second threaded hole 321. The second threaded hole 321 is coaxially arranged with the first threaded hole 21, and the pitches of the first threaded hole 21 and the second threaded hole 321 are different. The surface of the adjusting member 4 is sequentially provided with a first threaded section 41 and a second threaded section 42 along its axial direction. The first threaded section 41 is screwed with the first threaded hole 21, and the second threaded section 42 is screwed with the second threaded hole 321. Among them, under the action of an external force on the adjusting member 4, the pitch difference between the first threaded hole 21 and the second threaded hole 321 enables the sliding table 2 to slide relative to the base 1.

[0054] Specifically, the sliding table mechanism includes a base 1, a sliding table 2, a fixing member 3, and an adjusting member 4. The base 1 can be in the shape of a cube, and the shape of the sliding table 2 is adapted to the shape of the base 1. The sliding table 2 is also in the shape of a cube, and the sliding table 2 and the base 1 are slidably connected.

[0055] The sliding table 2 has a top surface, a bottom surface, and a plurality of side surfaces. Optionally, the sliding table 2 has four side surfaces. The four side surfaces of the sliding table 2 are defined as the first side surface, the second side surface, the third side surface, and the fourth side surface respectively. The first side surface and the second side surface are opposite to each other, and the third side surface and the fourth side surface are opposite to each other. A first threaded hole 21 extends from one side surface to the opposite side surface. For example, the first threaded hole 21 extends from the first side surface towards the second side surface. The sliding table 2 has a length direction and a width direction. The length direction is parallel to the axial direction of the first threaded hole 21, and the sliding direction of the sliding table 2 is parallel to the axial direction of the first threaded hole 21.

[0056] The sliding table 2 is connected to the base 1 through a sliding structure, and the sliding structure is not specifically limited.

[0057] Optionally, the sliding structure includes a crossed roller guide 7. The crossed roller guide 7 includes a first guide rail and a second guide rail that are slidably connected. The second guide rail realizes linear motion through the cooperation of crossed rollers with the first guide rail. A receiving groove is provided on the side of the sliding table 2 facing the base 1. The crossed roller guide 7 is located at the receiving groove. The first guide rail is fixedly connected to the base 1, and the second guide rail is fixedly connected to the sliding table 2. When the second guide rail moves on the first guide rail, the contact surface between the crossed rollers and the first guide rail generates rolling friction, which is beneficial to reducing the frictional resistance. The base 1 and the sliding table 2 can be slidably connected through two groups of crossed roller guides 7.

[0058] Optionally, the sliding structure includes a chute and a slider. A slider is provided on the side of the sliding table 2 facing the base 1, and a chute is provided on the side of the base 1 facing the sliding table 2. The slider and the chute are slidably matched, and the sliding table 2 and the base 1 are slidably connected through the slider and the chute.

[0059] The fixing member 3 is arranged on one side of the base 1, and the fixing member 3 faces the first side surface of the sliding table 2. The fixing member 3 includes a first connecting portion 31 and a fixing portion 32. The first connecting portion 31 is used to connect with the base 1, and the fixing portion 32 is used to mount the first adjusting member 4. The first connecting portion 31 can be connected to one side surface of the base 1 by welding, screwing or clamping. Optionally, a threaded hole is provided at one side surface of the base 1, and a mounting hole is provided on the first connecting portion 31. The mounting hole can be a through hole or a threaded hole. After the screw passes through the mounting hole, it is screwed into the threaded hole to realize the connection between the first connecting portion 31 and the base 1.

[0060] A second threaded hole 321 is formed in the fixing portion 32. The second threaded hole 321 is coaxially arranged with the first threaded hole 21, and the pitches of the first threaded hole 21 and the second threaded hole 321 are different. Optionally, the pitch of the second threaded hole 321 is greater than the pitch of the first threaded hole 21. Define the pitch of the first threaded hole 21 as the first pitch, and the pitch of the second threaded hole 321 as the second pitch.

[0061] The adjusting member 4 includes an adjusting rod and a force-applying portion 43. The force-applying portion 43 is located at one end of the adjusting rod. Along the axial direction of the adjusting rod, a first threaded section 41 and a second threaded section 42 are sequentially arranged on the circumferential surface of the adjusting rod. The first threaded section 41 is used to be screwed with the first threaded hole 21, and the second threaded section 42 is used to be screwed with the second threaded hole 321. The pitch of the second threaded section 42 is greater than the pitch of the first threaded section 41. The second threaded section 42 is close to the side where the force-applying portion 43 is located, which is beneficial to easily rotate the adjusting member 4.

[0062] It can be understood that the first threaded hole 21 and the second threaded hole 321 have the same helix direction, and the first threaded section 41 and the second threaded section 42 have the same helix direction. The adjusting rod is sequentially screwed into the second threaded hole 321 and the first threaded hole 21 to realize the connection between the adjusting member 4, the fixing member 3 and the sliding table 2.

[0063] The first threaded hole 21 and the first threaded section 41 form a first screw pair, and the second threaded hole 321 and the second threaded section 42 form a second screw pair.

[0064] The force-applying portion 43 facilitates the operator to apply an external force to the adjusting member 4. The operator can apply a clockwise or counterclockwise rotational force to the force-applying portion 43 by manual operation, or can also apply a clockwise or counterclockwise rotational force to the force-applying portion 43 by a working tool.

[0065] It can be understood that the side of the sliding table 2 facing away from the base 1 is used to mount the object to be moved. The object to be moved can be a workpiece to be processed or detected, and the object to be moved can also be an optical element, and the optical element is used to detect the workpiece.

[0066] Optionally, both the first threaded hole 21 and the second threaded hole 321 are right-handed threads, and the first threaded section 41 and the second threaded section 42 are also right-handed threads.

[0067] Optionally, both the first threaded hole 21 and the second threaded hole 321 are left-handed threads, and the first threaded section 41 and the second threaded section 42 are also left-handed threads.

[0068] For the convenience of description below, it is described by taking the first threaded hole 21, the second threaded hole 321, the first threaded section 41, and the second threaded section 42 all being right-handed threads as an example.

[0069] The sliding process of the sliding table 2 is described in detail below.

[0070] An external force is applied to the force application part 43 of the adjusting member 4, so that the adjusting member 4 rotates in the clockwise direction. When the adjusting member 4 rotates one circle, due to the different pitches of the first threaded hole 21 and the second threaded hole 321, based on the differential thread principle, the distance that the sliding table 2 moves is the pitch difference between the first pitch and the second pitch. For example, the first pitch of the first threaded hole 21 is 0.5 mm, the second pitch of the second threaded hole 321 is 0.55 mm, and the pitch difference between the first pitch and the second pitch is 0.05 mm. When the adjusting member 4 rotates one circle, the displacement of the sliding table 2 moving away from the fixing member 3 along the sliding direction is 0.05 mm. When the adjusting member 4 rotates in the clockwise direction, the sliding table 2 moves away from the fixing member 3 along the sliding direction. By adjusting the number of turns of the adjusting member 4, a fine adjustment of the position of the sliding table 2 is realized, and further a fine adjustment of the position of the object to be moved is realized.

[0071] An external force is applied to the force application part 43 of the adjusting member 4, so that the adjusting member 4 rotates in the counterclockwise direction. Taking the first pitch of 0.5 mm and the second pitch of 0.55 mm as an example, when the adjusting member 4 rotates one circle, the displacement of the sliding table 2 moving closer to the fixing member 3 along the sliding direction is 0.05 mm. When the adjusting member 4 rotates in the counterclockwise direction, the sliding table 2 moves closer to the fixing member 3 along the sliding direction. By adjusting the number of turns of the adjusting member 4, a fine adjustment of the position of the sliding table 2 is realized.

[0072] The sliding table 2 is slidably connected to the base 1. The fixing member 3 is provided on one side of the base 1. The sliding table 2 is provided with a first threaded hole 21, and the fixing member 3 is provided with a second threaded hole 321. The first threaded hole 21 and the second threaded hole 321 are coaxially arranged, and the pitches of the first threaded hole 21 and the second threaded hole 321 are different. The adjusting member 4 is screwed to the sliding table 2 through a first screw pair and screwed to the fixing member 3 through a second screw pair. The overall structure of the sliding table mechanism is simplified, and the assembly process is convenient.

[0073] An external force is applied to the adjusting member 4, causing the adjusting member 4 to rotate in the clockwise or counterclockwise direction. Based on the pitch difference between the first threaded hole 21 and the second threaded hole 321, the adjusting member 4 drives the slide table 2 to move along the base 1 towards or away from the fixing member 3, realizing a fine adjustment of the position of the object to be moved mounted on the slide table 2.

[0074] Part of the adjusting member 4 is integrated on the slide table 2. According to the differential thread principle, the displacement of the slide table 2 is finely adjusted, simplifying the structure of the slide table mechanism.

[0075] In an embodiment of the present invention, the adjusting member 4 is screwed to the slide table 2 through the first screw pair and screwed to the fixing member 3 through the second screw pair. Part of the adjusting member 4 is integrated on the slide table 2. According to the differential thread principle, the displacement of the slide table 2 is finely adjusted, simplifying the structure of the slide table mechanism and facilitating the miniaturization of the slide table mechanism.

[0076] In an alternative embodiment, the slide table mechanism further includes a locking member disposed at the end of the slide table 2, and the locking member is adapted to switch between a locked state and an unlocked state. In the locked state, the slide table 2 is locked to the base 1; in the unlocked state, under the action of an external force on the adjusting member 4, the slide table 2 can slide relative to the base 1.

[0077] Specifically, the locking member is located at the end of the slide table 2, that is, the locking member is provided on the side surface of the slide table 2, and the locking member can be operably switched between the locked state and the unlocked state. Optionally, at least one locking member is provided at the third side surface of the slide table 2, and at least one locking member is provided at the fourth side surface of the slide table 2.

[0078] After the slide table 2 drives the object to be moved to move to the target position along the sliding direction, the locking member locks the slide table 2 and the base 1, preventing the slide table 2 from moving or shaking due to external factors, ensuring the fixation of the slide table 2 at the target position, and further ensuring the fixation of the position of the object to be moved.

[0079] When it is necessary to adjust the position of the slide table 2 on the base 1, after releasing the locking state of the locking member on the slide table 2, an external force is applied to the adjusting member 4 in the clockwise or counterclockwise direction, and the slide table 2 slides relative to the base 1 until the slide table 2 moves to the target position, and the locking member locks the slide table 2 and the base 1 again in the fixed connection state.

[0080] In an embodiment of the present invention, the locking member is provided on the side surface of the slide table 2, and the locking member can be operably switched between the locked state and the unlocked state. When the locking member is in the locked state, the slide table 2 can be stably held at the target position on the base 1; when the locking member is in the unlocked state, the slide table 2 can move relative to the base 1 to flexibly adjust the position of the object to be moved.

[0081] Such asFigure 1 , Figure 2 and Figure 3 As shown in Figure 1 , Figure 2 and Figure 3 , in an alternative embodiment, the locking member includes a first movable connecting member 53 and a second movable connecting member 54. First connecting blocks 51 and second connecting blocks 52 are respectively disposed on two opposite side surfaces of the sliding table 2. The first connecting block 51 is provided with a first connecting hole, and the second connecting block 52 is provided with a second connecting hole. The first movable connecting member 53 is connected to the first connecting hole, and the first movable connecting member 53 is adapted to move along the axial direction of the first connecting hole to abut against or separate from the base 1. The second movable connecting member 54 is connected to the second connecting hole, and the second movable connecting member 54 is adapted to move along the axial direction of the second connecting hole to abut against or separate from the base 1.

[0082] Specifically, the first connecting block 51 is disposed at the third side surface of the sliding table 2, and the second connecting block 52 is disposed at the fourth side surface of the sliding table 2. The thicknesses of the first connecting block 51 and the second connecting block 52 are not greater than the thickness of the sliding table 2, and both the first connecting block 51 and the second connecting block 52 can be integrally formed with the sliding table 2. The first connecting block 51 and the second connecting block 52 can also be connected to the sliding table 2 by means of welding, screwing, clamping or the like.

[0083] The first connecting block 51 is provided with a through first connecting hole, which can be a threaded hole, and the number of the first connecting holes can be one or more. The first movable connecting member 53 can be a screw, and this screw is defined as the first screw, and the first screw is adapted to the first connecting hole.

[0084] The second connecting block 52 is provided with a through second connecting hole, which can be a threaded hole, and the number of the second connecting holes can be one or more. The second movable connecting member 54 can be a screw, and this screw is defined as the second screw, and the second screw is adapted to the second connecting hole.

[0085] It can be understood that there is an appropriate gap between the first connecting block 51 and the base 1, that is, there is a gap between the bottom surface of the first connecting block 51 and the top surface of the base 1; there is an appropriate gap between the second connecting block 52 and the base 1, that is, there is a gap between the bottom surface of the second connecting block 52 and the top surface of the base 1. The gaps between the first connecting block 51 and the second connecting block 52 and the base 1 can prevent friction from occurring between the first connecting block 51 and the second connecting block 52 and the base 1 during the movement of the sliding table 2, and ensure the smooth movement of the sliding table 2.

[0086] When it is necessary to move the sliding table 2, at the first connecting block 51, the first screw is screwed out along the axial direction of the first connecting hole, and at the second connecting block 52, the second screw is screwed out along the axial direction of the second connecting hole, thereby releasing the fixation of the sliding table 2.

[0087] After releasing the fixation of the sliding table 2 and applying an external force to the adjusting member 4, when the sliding table 2 drives the object to be moved on the sliding table 2 to move to the target position, at the first connecting block 51, a first screw is screwed in along the axis direction of the first connecting hole, so that the first screw abuts against the top surface of the base 1 corresponding to the first connecting block 51. At the second connecting block 52, a second screw is screwed in along the axis direction of the second connecting hole, so that the second screw abuts against the top surface of the base 1 corresponding to the second connecting block 52, thereby firmly fixing the sliding table 2 on the base 1.

[0088] In the embodiment of the present invention, by screwing in the first screw at the first connecting block 51 and the second screw at the second connecting block 52, the sliding table 2 can be firmly fixed on the base 1. By unscrewing the first screw at the first connecting block 51 and the second screw at the second connecting block 52, the fixation of the sliding table 2 can be released. The overall structure of the locking member is simple and the operation is convenient.

[0089] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, in an alternative embodiment, the sliding table mechanism further includes a stopper 6. The stopper 6 is disposed on the other side of the base 1 and is disposed opposite to the fixing member 3. The fixing member 3 has a first surface 322 facing the sliding table 2, and the stopper 6 has a second surface 622 facing the sliding table 2. The sliding table 2 is adapted to slide between the first surface 322 and the second surface 622.

[0090] Specifically, the sliding table mechanism further includes a stopper 6. The fixing member 3 is disposed opposite to the first side surface of the sliding table 2, and the stopper 6 is disposed opposite to the second side surface of the sliding table 2. The stopper 6 includes a connected second connecting portion 61 and a stopper portion 62. The second connecting portion 61 and the stopper portion 62 can both be plate-like bodies. The second connecting portion 61 can be connected to the base 1 by welding, screwing, clamping or the like.

[0091] Optionally, the second connecting portion 61 is provided with mounting holes. The number of the mounting holes is one or more. The mounting holes can be through holes or threaded holes. Threaded holes are provided at the side surface of the base 1. The threaded holes are coaxially disposed with the mounting holes. A fastening screw passes through the mounting hole of the second connecting portion 61 and is screwed into the threaded hole of the base 1 to realize the connection between the second connecting portion 61 and the base 1.

[0092] The fixing portion 32 of the fixing member 3 has a first surface 322 facing the sliding table 2, and the stopper portion 62 of the stopper 6 has a second surface 622 facing the sliding table 2. The distance between the first surface 322 and the second surface 622 is greater than the length dimension of the sliding table 2. The sliding table 2 is adapted to slide between the first surface 322 and the second surface 622.

[0093] When the sliding table 2 moves along the sliding direction towards the side close to the fixing member 3, the sliding table 2 moves to the first extreme position and abuts against the first surface 322 of the fixing member 3; when the sliding table 2 moves along the sliding direction towards the side close to the stopper 6, the sliding table 2 moves to the second extreme position and abuts against the second surface 622 of the stopper 6.

[0094] During the process of the sliding table 2 sliding along the base 1, the stopper 6 plays a role in limiting and protecting the sliding table 2, preventing the sliding table 2 from colliding with other structural members on the periphery of the sliding table 2 due to excessive movement. The fixing member 3 also plays a certain role in limiting and protecting the sliding table 2.

[0095] Optionally, a third threaded hole 621 is provided on the stopper portion 62 of the stopper 6. The third threaded hole 621 is coaxially arranged with the second threaded hole 321, and the pitch of the third threaded hole 621 is the same as that of the second threaded hole 321.

[0096] The first threaded hole 21 provided on the sliding table 2 penetrates through two opposite sides of the sliding table 2. Another first threaded hole 21 can also be extended from the second side surface of the sliding table 2 towards the first side surface. The adjusting member 4 can be installed on the side where the fixing member 3 is located, or the adjusting member 4 can also be installed on the side where the stopper 6 is located. When the adjusting member 4 is installed on the side where the fixing member 3 is located, an external force is applied to the adjusting member 4 on the side where the fixing member 3 is located, so that the sliding table 2 can slide relative to the base 1; when the adjusting member 4 is installed on the side where the stopper 6 is located, an external force is applied to the adjusting member 4 on the side where the stopper 6 is located, so that the sliding table 2 can slide relative to the base 1.

[0097] The third threaded hole 621 is provided on the stopper 6, and the first threaded hole 21 penetrates through two opposite sides of the sliding table 2. According to factors such as usage requirements, position requirements of the installation space, and convenience requirements of the operation space, the adjusting member 4 can be installed on the side where the fixing member 3 or the stopper 6 is located, which is beneficial to improving the flexibility of the sliding table mechanism.

[0098] As Figure 4 and Figure 5 shown, in an alternative embodiment, the sliding table 2 is provided with a receiving groove 22. The receiving groove 22 communicates with the first threaded hole 21, and partial sections of the first threaded section 41 and the second threaded section 42 are located in the receiving groove 22.

[0099] Specifically, extending from the first side surface of the sliding table 2 towards the second side surface of the sliding table 2, the sliding table 2 is provided with a receiving groove 22 and a first threaded hole 21 communicating with the receiving groove 22. The cross-section of the receiving groove 22 can be square, circular, etc. The cross-section of the receiving groove 22 has a horizontal dimension along the horizontal direction and a vertical dimension along the vertical direction, and both the horizontal dimension and the vertical dimension are larger than the diameter dimension of the second threaded section 42.

[0100] A partial section of the first threaded section 41 close to the second threaded section 42 and a partial section of the second threaded section 42 close to the first threaded section 41 are located in the accommodation groove 22. The accommodation groove 22 plays a certain role in dust prevention, preventing external impurities from adhering to the first threaded section 41 and the second threaded section 42 and affecting the flexibility of the rotation of the adjusting member 4.

[0101] In addition, when the size of the base 1 is fixed, a partial section of the first threaded section 41 and a partial section of the second threaded section 42 are located in the accommodation groove 22. When the adjusting member 4 is screwed to the fixing member 3 and the sliding table 2, the length dimension of the sliding table 2 is made to be equivalent to the length dimension of the base 1, which is beneficial to maximizing the bearing surface of the sliding table 2 and ensuring the stability of the object to be moved mounted on the sliding table 2.

[0102] The following will describe Figures 6 to 9 the sliding table device according to the embodiments of the present invention.

[0103] An embodiment of the present invention further provides a sliding table device. The sliding table device includes a first sliding table mechanism 100 and a second sliding table mechanism 200. At least one of the first sliding table mechanism 100 and the second sliding table mechanism 200 is the sliding table mechanism as described above. The sliding table device further includes a first connection assembly 400. The second sliding table mechanism 200 is connected to one side of the first sliding table mechanism 100 through the first connection assembly 400. The first sliding table mechanism 100 includes a first sliding table 120 and a first base 110 that are slidably connected. The first sliding table 120 is adapted to drive the second sliding table mechanism 200 to move in a first direction. The second sliding table mechanism 200 includes a second sliding table 220 and a second base 210 that are slidably connected. The second sliding table 220 is adapted to slide in a second direction, and the first direction intersects the second direction.

[0104] Optionally, the structure of one of the first sliding table mechanism 100 and the second sliding table mechanism 200 is the same as the structure of the sliding table mechanism described above. Thus, the sliding table device has the beneficial effects brought by the above sliding table mechanism.

[0105] Optionally, the structures of both the first sliding table mechanism 100 and the second sliding table mechanism 200 are the same as the structure of the sliding table mechanism described above. When the structures of the first sliding table mechanism 100 and the second sliding table mechanism 200 are the same, for the convenience of description, the structural members included in the first sliding table mechanism 100 are defined as a first base 110, a first sliding table 120, a first fixing member 130, a first adjusting member 140, a first locking member 150, and a first stopping member 160, and the structural members included in the second sliding table mechanism 200 are defined as a second base 210, a second sliding table 220, a second fixing member 230, a second adjusting member 240, a second locking member 250, and a second stopping member 260.

[0106] The first sliding table mechanism 100 and the second sliding table mechanism 200 are arranged in sequence along the vertical direction. The first sliding table 120 can slide along the first direction, and the second sliding table 220 can slide along the second direction. Both the first direction and the second direction are parallel to the horizontal direction. The first direction and the second direction intersect. Optionally, the first direction and the second direction are perpendicular to each other. The angle between the first direction and the second direction can also be an angle other than 90 degrees.

[0107] When assembling the sliding table device, adjust the orientations of the two sliding table mechanisms so that the first adjusting member 140 and the second adjusting member 240 are placed at 90 degrees, and then connect the first sliding table mechanism 100 and the second sliding table mechanism 200 through the first connecting assembly 400.

[0108] Optionally, the second sliding table mechanism 200 is located above the first sliding table mechanism 100. The second base 210 is in contact with the first sliding table 120. A first boss is convexly formed on the side surface of the first sliding table 120, and a second boss is convexly formed on the side surface of the second base 210. Mounting holes are formed on both the first boss and the second boss. The first connecting assembly 400 includes a bolt and a nut. After the bottom surface of the second base 210 of the second sliding table mechanism 200 is attached to the top surface of the first sliding table 120 of the first sliding table mechanism 100, the bolt passes through the mounting holes of the first boss and the second boss, and then the nut is screwed on to realize the connection between the first sliding table mechanism 100 and the second sliding table mechanism 200.

[0109] The object to be moved is installed on the second sliding table 220. Apply an external force to the first adjusting member 140, and the first sliding table 120 slides along the first base 110, driving the second sliding table mechanism 200 and the object to be moved to move along the first direction. After the first sliding table 120 moves into place, the first locking member 150 locks the first sliding table 120 and the first base 110. During the process of the first sliding table 120 sliding along the first base 110, the first stopping member 160 plays a protective role for the first sliding table 120. Apply an external force to the second adjusting member 240, and the second sliding table 220 slides along the second base 210, driving the object to be moved to move along the second direction. After the second sliding table 220 moves into place, the second locking member 250 locks the second sliding table 220 and the second base 210. During the process of the second sliding table 220 sliding along the second base 210, the second stopping member 260 plays a protective role for the second sliding table 220.

[0110] Thus, through the first sliding table mechanism 100 and the second sliding table mechanism 200, the position of the object to be moved can be adjusted in two intersecting directions, which is beneficial to improving the position accuracy of the object to be moved.

[0111] Such as Figure 8 and Figure 9As shown, in an alternative embodiment, the first connection assembly 400 includes a first connection plate 410, a first fastener 420, and a second fastener. The first connection plate 410 is clamped between the first sliding table 120 and the second base 210. The first connection plate 410 is connected to the first sliding table 120 by the first fastener 420, and the first connection plate 410 is connected to the second base 210 by the second fastener.

[0112] Specifically, the first connection assembly 400 includes a first connection plate 410, a first fastener 420, and a second fastener. The first connection plate 410 is a square body. The length dimension of the first connection plate 410 is adapted to the length dimension of the second base 210, and the width dimension of the first connection plate 410 is adapted to the width dimension of the second base 210. It can be understood that the width dimension of the second sliding table 220 is smaller than the width dimension of the second base 210.

[0113] The first connection plate 410 is clamped between the first sliding table 120 and the second base 210. Threaded holes are provided on the first sliding table 120, and countersunk holes are provided on the first connection plate 410. The number of threaded holes and the number of countersunk holes can both be multiple, and the multiple countersunk holes and the multiple threaded holes are arranged in one-to-one correspondence. The first fastener 420 is a countersunk head screw, and the countersunk head screw passes through the countersunk hole and is screwed into the threaded hole to realize the connection between the first connection plate 410 and the first sliding table 120.

[0114] First mounting holes 610 are provided on the second base 210. The first mounting holes 610 are provided in the edge area of the second base 210. Second mounting holes 620 are provided on the first connection plate 410. The number of the first mounting holes 610 and the second mounting holes 620 is not specifically limited. For example, four first mounting holes 610 are arranged at intervals in the circumferential direction of the second base 210, and four second mounting holes 620 are arranged at intervals in the circumferential direction of the first connection plate 410. The four first mounting holes 610 and the four second mounting holes 620 are arranged in one-to-one correspondence.

[0115] The second fastener can be a combination of a bolt and a nut. After the bolt passes through the first mounting hole 610 and the second mounting hole 620, a nut is screwed on to realize the connection between the second sliding table mechanism 200 and the first connection plate 410. The second fastener can also be a combination of a double-headed screw and a nut.

[0116] When assembling the sliding table device, first place the first connecting plate 410 on the first sliding table 120, align the multiple countersunk holes on the first connecting plate 410 with the multiple threaded holes on the first sliding table 120 one by one, and then screw the countersunk head screws into the corresponding countersunk holes and threaded holes to realize the connection between the first connecting plate 410 and the first sliding table mechanism 100. Then place the second sliding table mechanism 200 on the first connecting plate 410, adjust the position of the second adjusting member 240 so that the second adjusting member 240 forms a 90-degree angle with the first adjusting member 140, and then align the multiple first mounting holes 610 on the second sliding table 220 with the multiple second mounting holes 620 on the first connecting plate 410 one by one. Finally, after passing the bolts through the corresponding first mounting holes 610 and second mounting holes 620, screw on the nuts to realize the connection between the first connecting plate 410 and the second sliding table mechanism 200.

[0117] The first connecting plate 410 is clamped between the first sliding table 120 and the second base 210. The first connecting plate 410 is connected to the first sliding table 120 through the first fastener 420, and the first connecting plate 410 is connected to the second base 210 through the second fastener, which is beneficial to the firmness of the connection between the first sliding table mechanism 100 and the second sliding table mechanism 200. In addition, the assembly and disassembly processes are convenient.

[0118] It can be understood that the first mounting holes 610 for connecting with the first connecting plate 410 are also provided on the first base 110 of the first sliding table mechanism 100, and the countersunk holes for connecting with the first connecting plate 410 are also provided on the second sliding table 220 of the second sliding table mechanism 200. Thus, by swapping the positions of the first sliding table mechanism 100 and the second sliding table mechanism 200, the connection between the first sliding table mechanism 100 and the second sliding table mechanism 200 can also be realized, which is beneficial to improving the convenience of assembly.

[0119] When batch-assembling multiple sliding table mechanisms, any two sliding table mechanisms can be assembled together through the first connection component 400, which is beneficial to improving the versatility of the sliding table mechanism and at the same time beneficial to improving the assembly efficiency.

The third sliding table mechanism 300 includes a third sliding table 320 and a third base 310 that are slidably connected.

[0121] Specifically, the sliding table device further includes a third sliding table mechanism 300. The structures of the first sliding table mechanism 100, the second sliding table mechanism 200, and the third sliding table mechanism 300 are the same. The structural components included in the third sliding table mechanism 300 are defined as a third base 310, a third sliding table 320, a third fixing member 330, a third adjusting member 340, a third locking member 350, and a third stopping member 360.

Apply an external force to the second adjusting member 240, and the second sliding table 220 slides along the second base 210, driving the third sliding table mechanism 300 and the object to be moved to move in the second direction. Apply an external force to the third adjusting member 340, and the third sliding table 320 slides along the third base 310, driving the object to be moved to move in the third direction. After the third sliding table 320 moves in place, the third locking member 350 locks the third sliding table 320 and the third base 310. During the process of the third sliding table 320 sliding along the third base 310, the third stopping member 360 plays a protective role for the third sliding table 320.

[0124] The first direction and the second direction are parallel to the horizontal direction, and the first direction and the second direction are perpendicular to each other. The third direction is parallel to the vertical direction, and the third direction is perpendicular to the first direction and the second direction. Thus, the position of the object to be moved can be adjusted in three directions to achieve the purpose of precisely adjusting the position of the object to be moved.

[0125] For example, the object to be moved is an optical element. The optical element and the workpiece to be detected are arranged at intervals in the horizontal direction. The light beam emitted by the optical element has a first central plane in the vertical direction and a second central plane in the horizontal direction. The first sliding table 120 slides in the first direction, which can adjust the distance between the optical element and the workpiece. The second sliding table 220 slides in the second direction, which can adjust the first central plane of the optical element to be located at the part to be detected of the workpiece. The third sliding table 320 slides in the third direction, which can adjust the second central plane of the optical element to be located at the part to be detected of the workpiece. Through the movement in three directions, the position of the optical element is precisely adjusted, which is beneficial to improving the detection accuracy.

[0129] The second connection plate 510 is connected to the second slide 220. Optionally, the second connection plate 510 and the second slide 220 are connected by a screwing method. Threaded holes are provided on the second slide 220, and third mounting holes 630 are provided on the second connection plate 510. The third mounting holes 630 can be through holes or threaded holes. The third fastener 530 can be a screw, and the screw is screwed into the third mounting hole 630 and the threaded hole to realize the connection between the second connection plate 510 and the second slide 220.

[0130] First mounting holes 610 are also provided on the third base 310. The first mounting holes 610 are provided in an edge area of the third base 310. Fourth mounting holes 640 are provided on the third connection plate 520, and a plurality of fourth mounting holes 640 on the third connection plate 520 and a plurality of first mounting holes 610 on the third base 310 are arranged in one-to-one correspondence.

[0132] When assembling the third slide mechanism 300 and the second slide mechanism 200, first place the second connecting plate 510 on the second slide 220, adjust the third mounting holes 630 on the second connecting plate 510 and the threaded holes on the second slide 220 one by one, and then screw the screws into the corresponding third mounting holes 630 and threaded holes to achieve the connection between the second connecting plate 510 and the second slide mechanism 200. Then place the third base 310 of the third slide mechanism 300 on the third connecting plate 520, adjust the position of the third adjusting member 340 so that the axial direction of the third adjusting member 340 is consistent with the vertical direction, and then adjust the first mounting holes 610 on the third base 310 and the fourth mounting holes 640 on the third connecting plate 520 one by one, and finally pass the bolts through the corresponding first mounting holes 610 and fourth mounting holes 640, and then screw the nuts to achieve the connection between the third connecting plate 520 and the third slide mechanism 300.

[0133] It is understandable that the third slide 320 of the third slide mechanism 300 is further provided with a threaded hole connected to the first connecting plate 410. When assembling multiple slide mechanisms, any two slide mechanisms can be assembled together through the first connecting assembly 400, and any two slide mechanisms can be assembled together through the second connecting assembly 500, which is conducive to further improving the versatility of the slide mechanism and the efficiency of slide device assembly.

[0134] Optionally, the third adjusting member 340 is arranged on the side away from the second slide 220, that is, the third adjusting member 340 is located at the top of the third slide mechanism 300, which is convenient for applying external force to the third adjusting member 340 above the third slide mechanism 300 and is conducive to the convenience of operation.
