[0034] See also Figure 1-Figure 8 The present invention provides a gate cutting mechanism, comprising:

[0035] A bottom plate 1 is provided with a telescopic device, which includes a driving cylinder 2 and a connecting member 3 connected to a driving shaft of the driving cylinder 2, so that the connecting member 3 is driven by the driving shaft to move along the axial direction of the driving shaft;

[0036] The rotating member includes a telescopic cylinder 4 and a rotating plate 5. The telescopic cylinder 4 includes a cylinder body 41 and a telescopic shaft 42 connected to the cylinder body 41. The cylinder body 41 is installed on the connecting member 3. The rotating plate 5 is hinged to the connecting member 3. The rotating plate 5 is also connected to the telescopic shaft 42 to drive the rotating plate 5 to rotate through the telescopic shaft 42.

[0037] The cutting device is installed on the rotating plate 5. The cutting device includes a cutting cylinder 6 and a cutter 7 connected to the cutting cylinder 6, so that the cutting cylinder 6 drives the cutter 7 to move and then cuts off the gate.

[0038] In the above embodiment, the base plate 1 can be installed on the gripping fixture of the manipulator, and the gripping fixture of the manipulator is used to grip the workpiece, and there is a gate to be cut off on the workpiece, so that the gate cutting mechanism can cut off the gate along the edge of the product. The telescopic device is used to drive the connecting member 3 to a preset position along a linear motion, in fact, to drive the cutter 7 to a preset position; then the telescopic cylinder 4 drives the rotating plate 5 to rotate and push the cutter 7 to a position where the edge of the product is close to the gate, and then the cutting cylinder 6 drives the cutter 7 to move and cut off the gate. This embodiment can accurately adjust the cutter 7 to the position of cutting off the gate by setting the telescopic device and the rotating member, which is more stable than the technical solution of the gripping fixture of the manipulator in the prior art; and the adjustment of the telescopic cylinder 4 can make the cutter 7 close to the edge of the product, with less cutting residue and high cutting precision. This embodiment has the advantages of high stability, high cutting precision and less cutting residue. In addition, since the precise cutting of the gate can also reduce secondary rework, it can reduce the production cost and shorten the process time, thereby improving production efficiency.

[0039] Further, refer to Figure 1A guide rail 8 is also provided on the bottom plate 1, and the telescopic device further includes a slider 9 connected to the driving shaft, the slider 9 is slidably mounted on the guide rail 8, and the slider 9 is connected to the connecting member 3, so as to drive the connecting member 3 to move through the slider 9. By setting the slider 9 and the guide rail 8, the driving force required for driving the cylinder 2 can be reduced, which is beneficial to energy saving and can reduce the volume of the driving cylinder, thereby reducing the volume of the gate cutting mechanism.

[0040] As a preferred implementation of the above embodiment, refer to Figure 1-Figure 4 The connecting member 3 includes a connecting rod 31, an adjusting plate 32 and a mounting plate 33 which are connected in sequence.

Specifically, a mounting hole can be provided on the slider 9. The connecting rod 31 is mounted on the mounting hole and fixed by a screw. The rotating plate 5 is hinged to the hinge seat 331 so that the rotating plate 5 can rotate around the hinge point under the drive of the telescopic cylinder 4, thereby realizing the rotation of the rotating plate 5, thereby realizing the adjustment of the position of the cutter 7. The cutter 7 is adjusted to the gate cutting position, which is convenient for the subsequent cutting device to cut the gate.

[0041] Further, refer to Figure 4 and Figure 5 The connecting rod 31 is provided with a step 311, and the step 311 is provided with a plurality of through holes 312. The adjusting plate 32 is provided with an arc hole 321, and the arc hole 321 is detachably connected to the through hole 312 via a threaded member. The adjusting plate 32 is also provided with a vertical waist-shaped hole 322, and the mounting plate 33 is provided with a connecting hole, and the mounting plate 33 and the adjusting plate 32 are detachably connected via a threaded fastener. Here, we can also refer to the connecting rod 31 and the adjusting plate 32 as an adjustment assembly, which is mainly used when the telescopic device and the rotating member jointly adjust the position of the cutter 7 but still cannot make the cutter 7 reach the preset position (those skilled in the art can understand that for different products, the position of the cutter 7 that needs to be adjusted is different). Specifically, the arc-shaped hole 321 on the adjustment plate 32 can be arranged horizontally, and the position of the adjustment plate 32 can be adjusted by connecting the arc-shaped hole 321 to different through holes 312 on the step 311, thereby adjusting the horizontal position and angle of the cutter 7; in addition, the height of the mounting plate 33 can be adjusted by the waist-shaped hole 322 arranged vertically, thereby adjusting the height of the cutter 7. The mounting plate 33 here can be arranged vertically. In this way, through the auxiliary adjustment function of the connecting rod 31 and the adjustment plate 32, it can be ensured that the cutter 7 can accurately move to the gate cutting position, further improving the cutting accuracy.

[0042] Further, refer to Figure 2 , Figure 3 and Figure 8, two connecting blocks 10 arranged opposite to each other are also provided on the rotating plate 5, and a connecting rod 11 is also provided on the telescopic shaft 42, the telescopic shaft 42 is provided through the mounting plate 33, and the connecting rod 11 is respectively connected to the two connecting blocks 10. Specifically, a through hole or a blind hole can be provided on the connecting block 10, a circular block 14 can be provided on the telescopic shaft 42, and the connecting rod 11 is provided on the circular block 14, and the connecting rod 11 is respectively provided in the through hole or the blind hole of the connecting block 10, so that the telescopic shaft 42 is connected to the rotating plate 5, and then the telescopic shaft 42 can drive the rotating plate 5 to rotate around the hinge point, so as to adjust the position of the cutter 7.

[0043] Further, refer to Figure 2-Figure 3 , Figure 6-Figure 7 , the cutting cylinder 6 and the cutter 7 are respectively arranged on both sides of the rotating plate 5, the cutting cylinder 6 includes a body and a cylinder shaft connected to the body, the cutting device also includes a transmission rod 12, the cutter 7 is hinged to the rotating plate 5, and the transmission rod 12 connects the cutter 7 and the cylinder shaft. Specifically, the middle position of the cutter 7 is hinged to the rotating plate 5, the transmission rod 12 is hinged to the end of the cutter 7, a long hole 71 is arranged on the cutter 7, and the transmission rod 12 passes through the long hole 71 and is hinged to the cutter 7, so as to drive the cutter 7 through the transmission rod 12 so that the blade of the cutter 7 cuts off the gate. By arranging the cutter 7 and the cutting cylinder 6 on both sides of the rotating plate 5, the cutter 7 can always face the product before and after work, and it can be isolated by the rotating plate 5 so that the blade will not leak out and cause danger to the debugging and maintenance personnel.

[0044] Further, refer to Figure 2-Figure 3 , Figure 6-Figure 7 , a strip hole 51 is provided on the rotating plate 5, and the transmission rod 12 can move along the length direction of the strip hole 51 under the drive of the cylinder shaft to drive the cutter 7 to rotate. A limit plate 13 is also provided on the rotating plate 5, and a rotation space is formed between the limit plate 13 and the cutter 7, and the cutter 7 can rotate in the rotation space. The strip hole 51 is provided to enable the transmission rod 12 to move in the strip hole 51 and then drive the blade of the cutter to rotate to cut off the gate. The limit plate 13 mainly plays two roles, one is to limit the movement of the cutter 7 to prevent the cutter 7 from moving beyond the limit; the second is to play a protective role to prevent the cutter 7 from leaking out and scratching the operator.

[0045] Further, refer to Figure 1 , the number of the telescopic device, the connecting member 3, the rotating member and the cutting device are all two. This design can cut off two gates on the product at the same time, thereby improving the cutting efficiency.
