Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, and more specifically, to a transmission component and laser processing equipment. Background Technology

[0002] Synchronous belt drives are a common type of transmission. During use, the synchronous belt can impact fasteners such as screws, causing them to loosen and weakening the belt tension. In a slack state, the synchronous belt is prone to slippage, preventing effective transmission.

[0003] To ensure that the timing belt is always taut, a specific adjustment structure is typically used to adjust the tension. However, existing adjustment structures all require the removal of the equipment casing when adjusting the timing belt tension; moreover, the adjustment process is relatively cumbersome.

[0035] In related technologies, after prolonged transmission, the tension of a synchronous belt changes, causing it to become relatively slack. This can lead to slippage between the synchronous belt and the pulleys, resulting in poor transmission efficiency. Therefore, when the synchronous belt is in a relatively slack state, its tension needs to be adjusted promptly to ensure it remains taut.

[0036] The conventional method involves adjusting the position of the timing pulley on the guide rail. As the position of the timing pulley changes, the tension of the timing belt also changes. This requires removing the timing pulley from the guide rail, adjusting its position, and then fixing it back to the rail. This method not only requires disassembling the housing of the transmission component, making the operation quite complex, but also makes the fixing of the timing pulley and the locking between the timing belt and the timing pulley difficult because they are not on the same operating surface. The inventor has creatively discovered a way to adjust the tension of the timing belt without removing the timing pulley from the guide rail, thus simplifying the adjustment process.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] For ease of understanding, the X-axis in the attached figure represents the length of the guide rail, which is also the direction of movement of the synchronous belt; the Y-axis represents the width of the guide rail; and the Z-axis represents the height of the guide rail.

[0041] See Figure 1 and Figure 2 The transmission assembly described in this embodiment of the present invention includes a guide rail 10, a synchronous belt assembly 20, a displacement conversion mechanism, and a first locking member 40. Wherein:

[0042] The synchronous belt assembly 20 includes a synchronous belt 21, a synchronous pulley 22, and a synchronous pulley fixing member 23. The synchronous belt 21 and the synchronous pulley 22 are connected by a transmission mechanism, with the synchronous pulley 22 driving the synchronous belt 21 to move. The synchronous pulley 22 is connected to the guide rail 10 via the synchronous pulley fixing member 23. The transmission connection between the synchronous belt 21 and the synchronous pulley 22 can be, for example, a meshing transmission. Specifically, the inner surface of the synchronous belt 21 is provided with first sawtooth teeth, and the outer circumferential surface of the synchronous pulley 22 is provided with second sawtooth teeth that match the first sawtooth teeth. The first and second sawtooth teeth mesh with each other, thereby achieving meshing between the synchronous belt 21 and the synchronous pulley 22. The synchronous pulley 22 is connected to the synchronous pulley fixing member 23, and the synchronous pulley fixing member 23 is detachably connected to the guide rail 10, thus fixing the synchronous pulley 22 to the guide rail 10. This allows the synchronous belt 21 to transmit power along the length of the guide rail 10.

[0043] The displacement conversion mechanism is located on the side of the synchronous pulley fixing member 23 away from the guide rail 10, and is movably connected to the synchronous pulley fixing member 23. The first locking member 40 passes through the synchronous pulley fixing member 23 and is movably connected to the displacement conversion mechanism. By adjusting the length of the first locking member 40 within the displacement conversion mechanism, the displacement conversion mechanism moves relative to the synchronous pulley fixing member 23. Consequently, the synchronous pulley fixing member 23 moves along the length of the guide rail 10 within the guide rail 10 under the drive of the displacement conversion mechanism. The synchronous pulley 22 moves along the length of the guide rail 10 under the action of the synchronous pulley fixing member 23. Thus, the position of the synchronous pulley 22 on the guide rail 10 changes, and the tension of the synchronous belt 21 is adjusted. During this process, it is not necessary to remove the synchronous pulley 22 from the guide rail 10, and the synchronous belt 21 and the synchronous pulley 22 are always locked together. This greatly simplifies the adjustment steps and reduces the difficulty of operation.

[0044] By way of example only, a displacement conversion mechanism can be, for instance, a structure with an inclined plane. See also... Figure 1 and Figure 2 The displacement conversion mechanism with an inclined surface is, for example, a wedge block 30. The wedge block 30 is located on the side of the synchronous pulley fixing member 23 away from the guide rail 10. The wedge block 30 has a first inclined surface 31, and the first inclined surface 31 is slidably connected to the synchronous pulley fixing member 23. At the same time, the first locking member 40 passes through the guide rail 10 and the synchronous pulley fixing member 23 in sequence and is detachably connected to the wedge block 30.

[0045] Understandably, one end of the first locking member 40 passes through the guide rail 10 and the synchronous pulley fixing member 23 in sequence along the width direction parallel to the guide rail 10, and finally extends into the wedge block 30. The length of the first locking member 40 extending into the wedge block 30 is adjustable, that is, the "locking force" of the first locking member 40 on the wedge block 30 is adjustable.

[0046] As the dimension of one end of the first locking member 40 extending into the wedge block 30 increases, the timing pulley fixing member 23 slides along the first inclined surface 31, and the timing pulley 22 moves along the length of the guide rail 10 under the action of the timing pulley fixing member 23. Thus, the position of the timing pulley 22 on the guide rail 10 changes, and the tension of the timing belt 21 is adjusted. During this process, it is not necessary to remove the timing pulley 22 from the guide rail 10, and the timing belt 21 and the timing pulley 22 remain locked together. This greatly simplifies the adjustment steps and reduces operational difficulty.

[0047] See Figures 3 to 6To illustrate the adjustment process, let's take increasing the tension of the synchronous belt 21, i.e., adjusting the synchronous belt 21 to a taut state, as an example: First, extend one end of the first locking member 40 into the wedge block 30, and make the first inclined surface 31 of the wedge block 30 contact the synchronous pulley fixing member 23 and be in a relatively slidable state; through specific operations, the size of the first locking member 40 extending into the wedge block 30 is continuously increased, and the wedge block 30 will move towards the guide rail 10 along the inclined direction of the first inclined surface 31; under the limiting action of the first inclined surface 31, the synchronous pulley fixing member 23 will move in the opposite direction of the X-axis along the length direction of the guide rail 10; the synchronous pulley 22 will also move in the opposite direction of the X-axis under the driving action of the synchronous pulley fixing member 23, thereby increasing the tension of the synchronous belt 21, i.e., the synchronous belt 21 is taut, making it taut, and preventing slippage between the synchronous belt 21 and the synchronous pulley 22 during transmission.

[0048] The sliding connection between the synchronous pulley fixing member 23 and the first inclined surface 31 is described in detail below:

[0049] The synchronous pulley fixing member 23 includes a first surface and a second surface. The first surface is the side facing the guide rail 10, and this surface is parallel to the guide rail 10; the second surface is the side facing the first inclined surface 31, and this surface is, for example, the second inclined surface. The inclination angle of the second inclined surface is the same as the inclination angle of the first inclined surface 31, so as to facilitate the sliding connection between the second inclined surface and the first inclined surface 31.

[0050] It is easy to understand that the first surface is in contact with the guide rail 10, and there is an angle between the second inclined surface and the first surface. The second inclined surface is an inclined surface that is adapted to the first inclined surface 31, that is, the shape, size and inclination angle of the second inclined surface are the same as or similar to the first inclined surface 31, thereby ensuring that the sliding connection between the second inclined surface and the first inclined surface 31 is more stable and that deviation is less likely to occur during sliding.

[0051] For example, the timing pulley fixing member 23 has an irregular shape. For instance, it includes an integrally formed first part and a second part. The first part corresponds to the timing pulley 22, and the second part corresponds to the wedge block 30. Specifically, the first part can be configured as an annular shape adapted to the end face of the timing pulley 22. The timing pulley 22 contacts the annular shape through its end face, and then the timing pulley 22 is connected to the first part by a fixing member. The second part, for example, is configured as a wedge shape adapted to the wedge block 30. The wedge surface of this wedge shape is the second inclined surface, and it is slidably connected to the first inclined surface 31 through this wedge surface. The first surface of the timing pulley fixing member 23 can be understood as the sum of the annular side near the guide rail 10 and the wedge side near the guide rail 10.

[0052] It should be noted that the synchronous pulley fixing member 23 can also be configured in other shapes, as long as it can achieve a sliding connection with the first inclined surface 31 and fix the synchronous pulley 22. Furthermore, depending on the shape of the synchronous pulley fixing member 23, it may also have surfaces other than the first surface and the second inclined surface.

[0053] Preferably, the second inclined surface is provided with a groove 231, and the first inclined surface 31 is provided with a protrusion 311. The protrusion 311 is embedded in the groove 231 to achieve a sliding connection between the protrusion 311 and the groove 231. That is, the sliding connection between the second inclined surface and the first inclined surface 31 is achieved through the groove 231 and the protrusion 311. Specifically, the protrusion 311 is embedded in the groove 231, and the groove 231 can play a certain limiting role for the protrusion 311, thereby controlling the sliding path of the synchronous pulley fixing member 23 relative to the wedge block 30, and preventing the synchronous pulley fixing member 23 from deviating during the sliding process, thus avoiding the inability to accurately drive the synchronous pulley 22 to move.

[0054] Alternatively, a groove can be provided on the first inclined surface 31, and a protrusion adapted to the groove can be provided on the second inclined surface, which can also achieve a sliding connection between the second inclined surface and the first inclined surface 31. Its working principle is the same as that of the above-described method of providing a groove 231 on the second inclined surface and a protrusion 311 on the first inclined surface 31, which can be referred to and will not be repeated here.

[0055] In one optional embodiment, the inclination angle of the first inclined surface 31 is 30°-60°. The inclination angle of the first inclined surface 31 can be understood, for example, as the angle between the first inclined surface 31 and the guide rail 10. An inclination angle within the above range not only ensures that the tension of the synchronous belt 21 is within a suitable range (e.g., 35N-40N) when adjusting the tension, but also ensures that there is no significant resistance to the sliding between the first inclined surface 31 and the second surface during the adjustment process, and that the wedge block 30 does not occupy a large space.

[0056] Optionally, the inclination angle of the first inclined surface 31 can be 35°, 40°, 42°, 48°, 50°, 55°, or 58°, etc. In use, the inclination angle of the first inclined surface 31 can be determined according to the material of the wedge block 30. When the friction coefficient of the material used for the wedge block 30 is high, the inclination angle of the first inclined surface 31 can be appropriately reduced. For example, when the material of the wedge block 30 is aluminum alloy, the inclination angle of the first inclined surface 31 is 45°.

[0057] Alternatively, the displacement conversion mechanism can also be a structure with an arc surface. For example, the displacement conversion mechanism has a first arc surface that protrudes toward the side away from the synchronous belt 21; the synchronous pulley fixing member 23 has a second inclined surface that is inclined from the side away from the guide rail 10 toward the side closer to the guide rail 10, and the first arc surface is tangent to the second inclined surface; the length of the first locking member 40 changes within the displacement conversion mechanism, the first arc surface slides relative to the second inclined surface, and the synchronous pulley fixing member 23 moves within the guide rail along the length direction of the guide rail 10.

[0058] Understandably, one end of the first locking member 40 passes through the guide rail 10 and the synchronous pulley fixing member 23 in sequence along the width direction parallel to the guide rail 10, and finally extends into the displacement conversion mechanism. The length of the first locking member 40 extending into the displacement conversion mechanism is adjustable, that is, the "locking force" of the first locking member 40 on the displacement conversion mechanism is adjustable.

[0059] The first arc surface of the displacement conversion mechanism is tangentially arranged to the second inclined surface of the synchronous pulley fixing member 23. As the dimension of one end of the first locking member 40 extending into the displacement conversion mechanism increases, the displacement conversion mechanism slides along the second inclined surface toward the guide rail 10. Driven by the displacement conversion mechanism, the synchronous pulley fixing member 23 translates along the guide rail 10 toward the direction away from the synchronous belt 21. Thus, the position of the synchronous pulley 22 on the guide rail 10 changes, and the tension of the synchronous belt 21 is adjusted. During this process, it is not necessary to remove the synchronous pulley 22 from the guide rail 10, and the synchronous belt 21 and the synchronous pulley 22 remain locked together. This greatly simplifies the adjustment steps and reduces operational difficulty.

[0060] Taking increasing the tension of the synchronous belt 21, i.e., adjusting the synchronous belt 21 to a taut state, as an example, the adjustment process is explained in detail as follows: First, one end of the first locking member 40 is extended into the displacement conversion mechanism, and the portion of the first arc surface of the displacement conversion mechanism near its bottom end is tangent to the synchronous pulley fixing member 23 and is in a relatively slidable state; through specific operations, the dimension of one end of the first locking member 40 extending into the displacement conversion mechanism is continuously increased, and the displacement conversion mechanism slides along the second inclined surface towards the guide rail 10. Driven by the displacement conversion mechanism, the synchronous pulley fixing member 23 moves along the length of the guide rail 10 in a direction away from the synchronous belt 21; the synchronous pulley 22 also moves away from the synchronous belt 21 under the driving action of the synchronous pulley fixing member 23, thereby increasing the tension of the synchronous belt 21, i.e., the synchronous belt 21 is taut, keeping it in a taut state, and preventing slippage between the synchronous belt 21 and the synchronous pulley 22 during transmission.

[0061] Specifically, the second inclined surface has a groove parallel to its inclination direction, and the first arc surface has a buckle adapted to the groove, with the buckle at least partially embedded in the groove. Thus, the groove and buckle enable the positioning and sliding connection of the displacement conversion mechanism between the second inclined surface. When the displacement conversion mechanism slides relative to the synchronous wheel fixing member 23 under the action of the first locking member 40, the buckle will always be located in the groove, thereby limiting the sliding path of the displacement conversion mechanism; simultaneously, it can also limit the synchronous wheel fixing member 23, allowing it to move only along the length direction of the guide rail 10.

[0062] Alternatively, a slot can be provided on the first arc surface, and a corresponding buckle can be provided on the second inclined surface, with the buckle at least partially embedded in the slot. In this configuration, the connection and sliding method of the displacement conversion mechanism to the synchronous pulley fixing member 23 is similar to the above configuration, and will not be described again here. In an optional embodiment, the first locking member 40 includes an operating end and a locking end, wherein the locking end passes through the guide rail 10 and the synchronous pulley fixing member 23 and is movably connected to the displacement conversion mechanism, and the operating end is located on the side of the guide rail 10 opposite to the synchronous belt 21.

[0063] It is easy to understand that the locking end is the end extending into the displacement conversion mechanism, and the operating end is the other end of the first locking member 40. The side of the guide rail 10 closest to the synchronous belt 21 can be understood as the inner side of the guide rail 10, and the side of the guide rail 10 away from the synchronous belt 21 can be understood as the outer side of the guide rail 10. The operating end is located on the side of the guide rail 10 away from the synchronous belt 21, that is, the operating end is located on the outer side of the guide rail 10. Therefore, the operator can perform corresponding operations on the first locking member 40 from the outer side of the guide rail 10, thereby adjusting the size of the locking end extending into the displacement conversion mechanism, and thus adjusting the tension of the synchronous belt 21, making the operation simpler and more convenient.

[0064] In one alternative implementation, see Figure 1 , Figure 3 or Figure 5 The guide rail 10 has a groove 11 on the side facing the timing belt 21, and the timing pulley fixing member 23 is located in the groove 11. The timing pulley fixing member 23 is movable in the groove 11 along the length of the guide rail 10.

[0065] For example, the portion of the synchronous pulley fixing member 23 near the guide rail 10 can be embedded in the groove 11, allowing the groove 11 to provide a certain positioning function for the synchronous pulley fixing member 23, facilitating the assembly between the synchronous pulley fixing member 23 and the guide rail 10. This also improves the stability of the connection between the synchronous pulley fixing member 23 and the guide rail 10.

[0066] Meanwhile, the groove 11 can limit the movement of the synchronous pulley fixing member 23, ensuring that the synchronous pulley fixing member 23 moves along the length direction of the groove 11, thereby driving the synchronous pulley 22 to move, changing the position of the synchronous pulley 22 on the guide rail 10, and adjusting the tension of the synchronous belt 21.

[0067] It is understandable that the shape of the groove 11 can be set according to the shape of the synchronous pulley fixing member 23. That is, the shape of the groove 11 can be the same as or similar to the shape of the first surface of the synchronous pulley fixing member 23, so that the groove 11 can be positioned by the second inclined surface of the synchronous pulley fixing member 23.

[0068] For example, in the height direction of the guide rail 10, the size of the groove 11 is equal to or slightly larger than the size of the synchronous pulley fixing member 23, thus the groove 11 can restrict the movement of the synchronous pulley fixing member 23 in the height direction of the guide rail 10. Alternatively, in the length direction of the guide rail 10, the size of the groove 11 is larger than the size of the synchronous pulley fixing member 23, allowing the synchronous pulley fixing member 23 to move a certain distance in the length direction of the guide rail 10 to adjust the tension of the synchronous belt 21. The specific size of the groove 11 being larger than the synchronous pulley fixing member 23 in the length direction of the guide rail 10 can be determined based on the range of tension adjustment of the synchronous belt 21. If the tension adjustment range of the synchronous belt 21 needs to be larger, this size can be set larger, and vice versa.

[0069] In one alternative implementation, see Figure 1 The transmission assembly also includes a second locking member 50 and a third locking member 60; the groove 11 has multiple strip holes and a circular hole 12, the multiple strip holes include a first strip hole 13 and a second strip hole 14; the first locking member 40 passes through the circular hole 12 and is detachably connected to the displacement conversion mechanism, the second locking member 50 passes through the synchronous wheel 22 and is detachably connected to the first strip hole 13, and the third locking member 60 passes through the second strip hole 14 and is detachably connected to the synchronous wheel fixing member 23.

[0070] In other words, the first locking member 40 connects the guide rail 10, the synchronous wheel fixing member 23, and the displacement conversion mechanism; the second locking member 50 connects the synchronous wheel 22, the synchronous wheel fixing member 23, and the guide rail 10; and the third locking member 60 connects the guide rail 10 and the synchronous wheel fixing member 23.

[0071] The circular hole 12 serves to limit the movement of the first locking member 40, allowing it to move only along the width of the guide rail 10. In other words, the first locking member 40 can only change its dimensions extending into the displacement conversion mechanism. The lengths of the first strip hole 13 and the second strip hole 14 are parallel to the length of the guide rail 10. This means that the first strip hole 13 and the second strip hole 14 allow the synchronous pulley fixing member 23 to move a certain distance along the length of the guide rail 10, and the lengths of the first strip hole 13 and the second strip hole 14 determine the magnitude of this movement.

[0072] For example, there is one first strip-shaped hole 13 and two second strip-shaped holes 14, arranged in an isosceles triangle. Correspondingly, there is one second locking member 50 and two third locking members 60. The second locking member 50 passes sequentially through the central shaft of the synchronous pulley 22, the first part of the synchronous pulley fixing member 23, and the second strip-shaped hole 14, connecting the guide rail 10, the synchronous pulley 22, and the synchronous pulley fixing member 23; the two third locking members 60 pass sequentially through the second strip-shaped hole 14 and the synchronous pulley fixing member 23, connecting the upper and lower ends of the guide rail 10 and the synchronous pulley fixing member 23. This allows the connection points between the guide rail 10 and the synchronous pulley fixing member 23 to be distributed in an isosceles triangle, improving the stability of the connection between them.

[0073] Preferably, the first locking member 40, the second locking member 50 and the third locking member 60 are all bolts, and the locking function of the first locking member 40, the second locking member 50 and the third locking member 60 can be achieved by the nut corresponding to the bolt.

[0074] See Figure 7 The laser processing equipment 100 described in this embodiment includes a frame 101, a cover plate 102, a laser head 103, and a transmission assembly as described above. The laser head 103 is connected to the transmission assembly via a connector 105, and the transmission assembly enables the movement of the laser head 103, thereby achieving processing of different areas.

[0075] The laser head 103 can be fixedly connected to the timing belt 21, for example, via a connector 105. Driven by the timing belt 21, the laser head 103 moves to process different locations or areas of the product to be processed. The laser processing equipment described in this application can be, for example, a laser 3D printer or other laser printer or laser engraving machine that requires the use of transmission components to move the laser head 103.

[0076] See also Figure 7The laser processing equipment 100 described above also includes, for example, a frame 101 and a cover plate 102. The frame 101 and the cover plate 102 together form the processing space 104 of the laser processing equipment 100. The cover plate 102 may be rotatably connected to one side wall of the frame 101 to open or close the processing space 104.

[0077] By way of example only, the frame 101 can be, for example, a square frame with an opening at the top. The cover plate 102 is disposed at the open end of the square frame and pivotally connected to the top edge of any one of the four side walls of the square frame. Thus, the opening or closing of the processing space 104 can be achieved by rotating the cover plate 102 around the pivot axis. The cover plate 102 can also be rotatably connected to the frame 101 in other ways, as long as it can achieve the opening or closing of the processing space 104. This application does not specifically limit the connection method between the cover plate 102 and the frame 101.

[0078] Optionally, both the transmission assembly and the laser head 103 are located within the processing space 104. The transmission assembly can be connected to the inner wall of the frame, for example, to secure it. Alternatively, the transmission assembly can be connected to the frame 101 via its corresponding guide rail 10. Driven by the transmission assembly, the laser head 103 moves within the processing space 104 to process different areas or locations of the product to be processed.

[0079] Preferably, at least a portion of the cover plate 102 is configured as a semi-transparent window, through which operators can observe in real time the movement of the laser head 103 within the processing space 104 and its processing status of the product to be processed. Simultaneously, the semi-transparent window can also filter the high-power laser output and reflection from the laser head 103, serving as an isolation and protection for the user.

[0080] join Figures 8 to 11 The following will provide a detailed description of the specific structure of the connector 105 and its position and connection relationship with the timing belt 21:

[0081] The laser head is connected to the synchronous belt in the transmission assembly via a connector 105. The connector 105 includes two oppositely arranged meshing parts 1051, which are located on one side of the synchronous belt. The surfaces of the two meshing parts 1051 that are opposite to each other and the surfaces facing the synchronous belt are provided with teeth. When the synchronous belt 21 is annular, the surfaces of the two meshing parts 1051 facing the synchronous belt 21 mesh with the synchronous belt 21.

[0082] For example, such as Figure 8 and Figure 9As shown, the synchronous belt 21 is annular, which can be understood as a one-piece annular structure, meaning the synchronous belt 21 does not have a connecting end. The main body of the meshing part 1051 can be, for example, a quadrangular prism with a certain extension length, with teeth provided on two adjacent sides of the quadrangular prism. One of the two sides is parallel to the synchronous belt 21, and the other is perpendicular to the synchronous belt 21. The side perpendicular to the synchronous belt 21 can be, for example, the surface where the two meshing parts 1051 are positioned opposite each other; the side parallel to the synchronous belt 21 can be, for example, the surface where the two meshing parts 1051 face the synchronous belt 21. When the synchronous belt 21 is a closed annular structure, since the annular structure itself is a one-piece structure, the two meshing parts 1051 can mesh with the synchronous belt 21 simply through the teeth on their sides facing the synchronous belt 21.

[0083] When the synchronous belt 21 is strip-shaped, such as Figure 10 and Figure 11 As shown, the synchronous belt 21 forms a loop by connecting its two ends together, thereby enabling transmission between the synchronous belt 21 and the synchronous pulley. At this point, the two ends of the synchronous belt 21 need to be connected by a connector 105. Bent sections 211 are provided at both ends of the synchronous belt 21. These bent sections 211 are bent towards the direction between the two meshing portions 1051, and the resulting bent sections 211 are located between the opposing surfaces of the two meshing portions 1051. That is, the bent sections 211 at both ends are clamped between the two opposing surfaces of the two meshing portions 1051, so that the bent sections 211 can be engaged by the teeth on the opposing surfaces of the two meshing portions 1051; simultaneously, the surfaces of the two meshing portions 1051 facing the synchronous belt 21 engage with the non-bent sections 212 at the ends of the synchronous belt 21. Thus, the connector 105 not only connects the two ends of the synchronous belt 21 together, but also connects the connector 105 to the synchronous belt 21.

[0084] The connector 105 described above is compatible with both annular and strip synchronous belts, offering excellent compatibility. This avoids the need to replace different connectors for different operating conditions, effectively reducing production costs.

[0085] Optionally, such as Figure 8 and Figure 10As shown, the connector 105 also includes a clamping portion, which is disposed opposite to the two engaging portions 1051 and located on the other side of the synchronous belt. The clamping portion and the two engaging portions 1051 are clamped and fixed to the synchronous belt 21 between them. The clamping portion and the two engaging portions 1051 are, for example, integrally formed, wherein the clamping portion and the two engaging portions 1051 are respectively located on both sides of the synchronous belt 21. By adjusting the distance between the clamping portion and the two engaging portions 105, or by adjusting the clamping force between the clamping portion and the two engaging portions 105 through other fasteners, the synchronous belt 21 located between the clamping portion and the two engaging portions 105 can be clamped to achieve the connection between the connector 105 and the synchronous belt 21.

[0086] Optionally, see [link to relevant documentation] Figures 8 to 11 The clamping part includes a detachably connected fixing part 1052 and an adjusting part 1053. The adjusting part 1053 is located between the fixing part 1052 and the timing belt 21. The surface of the fixing part 1052 facing the adjusting part 1053 is provided with a third inclined surface, and the surface of the adjusting part 1053 facing the fixing part 1052 is provided with a fourth inclined surface. The third and fourth inclined surfaces have opposite inclination directions and the same inclination angle. The third and fourth inclined surfaces are in contact with each other. The adjusting part 1053 is movable relative to the fixing part 1052 along the third inclined surface to adjust the clamping force of the clamping part and the two majority meshing parts 1051 on the timing belt 21.

[0087] It is understandable that when the adjusting part 1053 moves along the third inclined plane towards the direction closer to the fixing part 1052, the overlapping area of ​​the third and fourth inclined planes increases. At this time, the dimensions of the adjusting part 1053 and the fixing part 1052 in the direction in which they overlap with the synchronous belt 21 also increase. That is, the dimension of the clamping part in this opposite direction increases, thereby reducing the distance between the clamping part and the two engaging parts 1051, and increasing the clamping force of the clamping part and the two engaging parts 1051 on the synchronous belt 21. Similarly, when the adjusting part 1053 moves along the third inclined plane away from the fixing part 1052, the overlapping area of ​​the third and fourth inclined planes decreases. At this time, the dimensions of the adjusting part 1053 and the fixing part 1052 in the direction in which they overlap with the synchronous belt 21 also decrease. That is, the dimension of the clamping part in this direction decreases, thereby increasing the distance between the clamping part and the two engaging parts 1051, and decreasing the clamping force of the clamping part and the two engaging parts 1051 on the synchronous belt 21.

[0088] Preferably, a nearly cylindrical "cylindrical protrusion" is provided on the surface of the fixing part 1052 facing the synchronous belt 21, that is, on the third inclined surface, and a "cylindrical groove" matching the "cylindrical protrusion" is provided on the surface of the adjusting part 1053 away from the synchronous belt 21, that is, on the fourth inclined surface. The fixing part 1052 and the adjusting part 1053 can be detachably connected by embedding the "cylindrical protrusion" into the "cylindrical groove".

[0089] The fixing part 1052 and the two engaging parts 1051 are provided with threaded holes on the same side end face. The laser head 103 can be connected to the corresponding threaded holes by fasteners such as bolts, so as to connect the laser head 103 to the timing belt 21 through the connector 105. In this way, the laser head 103 can move under the drive of the timing belt 21.
