[0028] The following will further illustrate the technical solutions of the present invention with reference to the accompanying drawings and through specific implementation manners.

[0029] Please refer to Figure 1 and Figure 2As shown in the figure, the utility model discloses a clamping mechanism, which includes a clamping member. The clamping member includes a fixing plate 1, an adjusting member and an air pump. A first clamping block 4 and a second clamping block 5 that can slide along it are connected to the fixing plate 1. The fixed end of the adjusting member is connected to the fixing plate 1, and both the first clamping block 4 and the second clamping block 5 are connected to the telescopic end of the adjusting member. A number of through holes 2 are also provided on the fixing plate 1, and the air pump is communicated with all the through holes 2.

[0030] It should be noted that when the air pump of the utility model works, air pressure can be applied to the surface of the workpiece through these through holes 2 to form an adsorption force. The telescopic movement of the adjusting member can accurately control the opening and closing distance of the first clamping block 4 and the second clamping block 5 to achieve tight clamping of the workpiece. The adsorption force and the clamping force can act together, greatly enhancing the stability of the clamping mechanism for clamping the workpiece, and solving the problem that the existing technology only clamps the workpiece by the first clamping block 4 and the second clamping block 5 with unstable clamping.

[0031] Specifically, the clamping mechanism includes a connecting block 3. A sliding groove 10 is provided on the fixing plate 1. One end of the connecting block 3 is located in the sliding groove 10, and the second end of the connecting block 3 is connected to the first clamping block 4 or the second clamping block 5.

[0032] Specifically, the adjusting member includes a motor, a threaded rod and a connecting plate. The motor is connected with a driving gear, the threaded rod is threadedly connected with a driven gear, the connecting plate is connected to the threaded rod and the connecting block 3 and is used to push the connecting block 3, and the driving gear meshes with the driven gear.

[0033] The motor of the utility model serves as a power source. By driving the driving gear to rotate, the driven gear meshing with it is driven to rotate. The driven gear is threadedly connected with the threaded rod. Therefore, when the driven gear rotates, the threaded rod will generate a linear motion along its axis. The threaded rod is connected to the connecting plate. Therefore, when the threaded rod moves, it will drive the connecting plate, the first clamping block 4 and the second clamping block 5 to move, so as to adjust the opening and closing distance of the first clamping block 4 and the second clamping block 5.

[0034] Specifically, the clamping mechanism further includes a locking member. Limiting grooves are provided on the first clamping block 4 and the second clamping block 5, and a number of limiting holes 7 are provided on the connecting block 3. The number of limiting holes 7 are distributed at intervals, and the locking member passes through the limiting groove and any one of the limiting holes 7. When the positions of the first clamping block 4 and the second clamping block 5 need to be adjusted, first slide the first clamping block 4 and the second clamping block 5 to the appropriate positions, and then make the locking member pass through the limiting groove and the limiting hole 7 communicated with the limiting groove, and the first clamping block 4 and the second clamping block 5 can be locked, which is very simple.

[0035] Specifically, the clamping mechanism further includes a buffer pad 8. The first clamping block 4 and the second clamping block 5 are both connected to the buffer pad 8.

[0036] Specifically, the buffer pad 8 is provided with anti-slip lines.

[0037] The buffer pad 8 serves as the contact layer between the first clamping block 4 and the second clamping block 5 and the workpiece, playing a role in buffering and shock absorption. During the clamping process, the buffer pad 8 can absorb the impact generated by the first clamping block 4 and the second clamping block 5 on the workpiece, avoiding damage to the workpiece. The anti-slip pattern can increase the friction between the first clamping block 4 and the second clamping block 5 and the workpiece, helping to prevent problems such as sliding or falling off when clamping the workpiece.

[0038] Specifically, the clamping mechanism further includes a sensor 6. The sensor 6 is connected to the fixing plate 1 and is used to identify whether the workpiece abuts against the fixing plate 1. The air pump is in signal connection with the sensor 6. The sensor 6 of the present utility model is a pressure sensor 6. When there is a workpiece on the fixing plate 1, the pressure sensor 6 will send a first signal to the air pump, and the air pump will start to pump air to suck the workpiece, and the workpiece can be adsorbed on the fixing plate 1.

[0039] Specifically, the clamping mechanism further includes a fixing block 9 and at least two clamping members. The adjacent clamping members are arranged in opposite directions, and the fixing block 9 is connected to the fixing plate 1 of all the clamping members.

[0040] The present utility model includes two clamping members. When it is necessary to clamp the workpiece, the two fixing plates 1 are placed in the gap between adjacent workpieces, and then the motors on the two fixing plates 1 are driven simultaneously. The first clamping block 4 and the second clamping block 5 on each fixing plate 1 approach each other and clamp the workpiece, realizing the simultaneous clamping of two workpieces.

[0041] Specifically, the clamping mechanism further includes a motor. The motor is connected to the fixing block 9 and is used to drive the fixing block 9 to rotate.

[0042] Specifically, the clamping mechanism further includes an X-axis guide rail, a Y-axis guide rail, and a Z-axis guide rail. The Y-axis guide rail is connected to the X-axis guide rail and the Z-axis guide rail, and the Z-axis guide rail is connected to the motor.

[0043] The X-axis guide rail, the Y-axis guide rail, and the Z-axis guide rail together constitute a three-dimensional motion system of the first clamping block 4 and the second clamping block 5, enabling the first clamping block 4 and the second clamping block 5 to flexibly reach any position. Through the rotational motion of the motor, the fixing plate 1 can be rotated to be parallel to the workpiece, ensuring that the workpiece is closely attached to the fixing plate 1.

[0044] So far, the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
