[0029] The following further illustrates the technical solutions of the present utility model with reference to the accompanying drawings and through specific embodiments.
[0030] Please refer to Figure 1 - Figure 2 As shown, the present utility model designs a clamping mechanism, which includes a fixed block 1, a first clamping plate 2, a second clamping plate 3, a first telescopic plate 4, and a second telescopic plate 5. The first clamping plate 2 and the second clamping plate 3 are respectively disposed at both ends of the fixed block 1 and are slidably connected to the fixed block 1. The first clamping plate 2 is provided with a first sliding groove 13 along its length direction, and the second clamping plate 3 is provided with a second sliding groove 14 along its length direction. One end of the first telescopic plate 4 is located in the first sliding groove 13 and can slide along the first sliding groove 13, and one end of the second telescopic plate 5 is located in the second sliding groove 14 and can slide along the second sliding groove 14.
[0031] The first telescopic plate 4 and the second telescopic plate 5 of the present utility model can respectively slide along the sliding grooves on the first clamping plate 2 and the second clamping plate 3. By adjusting the positions of the first telescopic plate 4 and the second telescopic plate 5, the clamping range of the clamping mechanism can be easily changed, enabling it to clamp workpieces of various sizes from short to long, and there is no need to frequently stop the machine to replace the clamping mechanism during the production process, improving the production efficiency.
[0032] Specifically, the telescopic ends of the first driving devices are connected to the first clamping plate 2 and the second clamping plate 3 respectively, and the fixed ends of the first driving devices are connected to the fixed block 1.
[0033] Specifically, both the first telescopic plate 4 and the second telescopic plate 5 are connected to the telescopic ends of the second driver, and both the first clamping plate 2 and the second clamping plate 3 are connected to the fixed ends of the second driver. Both the first driver and the second driver are telescopic push rods.
[0034] Specifically, the clamping mechanism further includes a motor and a linear module. The motor is connected to the fixed block 1 and is used to drive the fixed block 1 to rotate, and the linear module is connected to the motor.
[0035] Specifically, the clamping mechanism further includes a first clamping block 6 and a second clamping block 7. The first clamping block 6 is connected to the first telescopic plate 4, and the second clamping block 7 is connected to the second telescopic plate 5 at a position corresponding to the first clamping block 6.
[0036] Specifically, the clamping mechanism further includes a third clamping block 8 and a fourth clamping block 9. The third clamping block 8 is connected to the first clamping plate 2, and the fourth clamping block 9 is connected to the second clamping plate 3 at a position corresponding to the third clamping block 8. The clamping distance between the first clamping block 6 and the second clamping block 7 is the same as the clamping distance between the third clamping block 8 and the fourth clamping block 9.
[0037] It should be noted that the linear module of the present utility model includes a Z-axis guide rail, an X-axis guide rail, and a Y-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. When clamping a workpiece, the operator starts the motor, and the motor drives the fixed block 1 to rotate. After rotating until the fixed block 1 is parallel to the top side of the workpiece, the motor is turned off, and the fixed block 1 is moved along the linear module to abut against the workpiece. Then the second driver is started. The telescopic ends of the second driver are respectively connected to the first telescopic plate 4 and the second telescopic plate 5. By controlling the telescoping of the second driver, the first telescopic plate 4 and the second telescopic plate 5 can be synchronously pulled. When the size of the first telescopic plate 4 matches the length of the workpiece, the second driver is turned off, and the first driver is started. The telescopic ends of the first driver are respectively connected to the first clamping plate 2 and the second clamping plate 3. The telescopic action of the first driver will simultaneously pull the first clamping plate 2 and the second clamping plate 3. When both the first clamping block 6 and the second clamping block 7 abut against the workpiece, the third clamping block 8 and the fourth clamping block 9 will also abut against the workpiece, greatly improving the clamping stability.
[0038] Specifically, the clamping mechanism further includes a first limiting post 11. The first limiting post 11 is connected to the fixed block 1, and both the first clamping plate 2 and the second clamping plate 3 are provided with limiting grooves 10, and the first limiting post 11 is limited in the limiting grooves 10.
[0039] Specifically, the clamping mechanism further includes a second limiting post 12. Both the first telescopic plate 4 and the second telescopic plate 5 are connected to the second limiting post 12, and the second limiting post 12 is limited in the first sliding groove 13 or the second sliding groove 14.
[0040] When the first driver drives the first clamping plate 2 and the second clamping plate 3 to move, the first limiting column 11 will slide within the limiting groove 10, thereby restricting the maximum and minimum ranges of the clamping width. The second limiting column 12 is connected to the first telescopic plate 4 and the second telescopic plate 5 and is limited within the first sliding groove 13 or the second sliding groove 14, restricting the telescopic ranges of the first telescopic plate 4 and the second telescopic plate 5. The second limiting column 12 and the first limiting column 11 also play a guiding role, ensuring that the first clamping plate 2, the second clamping plate 3, the first telescopic plate 4 and the second telescopic plate 5 can move along a predetermined trajectory, avoiding adverse situations such as deviation, which helps to improve the accuracy and reliability of the clamping mechanism.
[0041] Specifically, the clamping mechanism further includes a locking member 16. A plurality of through holes 15 are provided at intervals in the length direction of the first clamping plate 2 and the second clamping plate 3. The first clamping block 6 and the second clamping block 7 are both provided with arc-shaped grooves. The locking member 16 passes through the arc-shaped groove and any one of the through holes 15 to adjust the positions of the first clamping block 6 and the second clamping block 7. Before clamping the workpiece, according to the shape and size of the workpiece, the positions of the first clamping block 6 and the second clamping block 7 are finely adjusted. Once the positions of the first clamping block 6 and the second clamping block 7 are adjusted in place, the locking member 16 can lock the first clamping block 6 and the second clamping block 7 to prevent them from moving during the clamping process, which helps to maintain the stability of the clamping.
[0042] Specifically, the clamping mechanism further includes anti-slip pads. The first clamping block 6, the second clamping block 7, the third clamping block 8 and the fourth clamping block 9 are all connected with anti-slip pads.
[0043] The anti-slip pads are connected to the first clamping block 6, the second clamping block 7, the third clamping block 8 and the fourth clamping block 9, significantly increasing the friction between the first clamping block 6, the second clamping block 7, the third clamping block 8, the fourth clamping block 9 and the workpiece, which helps to prevent the workpiece from sliding or falling off due to vibration or impact during the clamping process, improving the stability and reliability of the clamping. The anti-slip pads are made of rubber or silica gel, which can effectively reduce the wear and scratch of the clamping blocks on the surface of the workpiece while increasing the friction.
[0044] So far, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention 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 invention.
