[0002] The forklift mast chain plate is an important part of the forklift, used to install the lifting chain. The processing of the forklift mast chain plate involves drilling, and the drilling position is at the top of the part. The forklift mast chain plate needs to be fixed vertically to facilitate drilling. Due to the irregular shape of the forklift mast chain plate, it is necessary to rely on a clamp to position and clamp the forklift mast chain plate before drilling. However, the existing forklift mast chain plate drilling tooling has the following defects:

[0003] 1. There are many different sizes of forklift door frame chain plates corresponding to different forklift models. The existing forklift door frame chain plate drilling tooling can only be used for a certain forklift door frame chain plate, and cannot be used for other forklift door frame chain plates. As a result, there are many types of forklift door frame chain plate drilling tooling, which not only has high tooling manufacturing costs, but also requires replacement of tooling when processing different forklift door frame chain plates, which is time-consuming and labor-intensive, affecting processing efficiency.

[0004] 2. It is inconvenient to position and clamp on the vertical machining center, and it cannot be used on the vertical machining center. Utility Model Content

[0035] Among them, positioning pin holes 101 are opened in the middle of the left and right ends of the base plate 1, and positioning pins 12 for positioning on the vertical machining center are installed in the positioning pin holes 101, so that the device can be accurately positioned on the vertical machining center. Waist-shaped grooves 102 for fixed installation on the vertical machining center are opened at the four corners of the base plate 1. The device can be fixed to the vertical machining center by bolts, which is convenient for drilling holes for the chain plate 14 on the vertical machining center. A lifting ring 13 is fixedly connected to the waist-shaped groove 102 by threads, which is convenient for the transportation and installation of the device.

[0036] Among them, the positioning block 5 is provided with multiple pieces according to the different sizes of the chain plate 14. By replacing the positioning block 5, the positioning requirements of the bottom of different chain plates 14 can be met, thereby achieving the purpose of universality, improving the universality and practicality of the device, reducing the tooling manufacturing cost, and only needing to replace the positioning block 5 when processing different chain plates 14, without replacing the entire tooling, thereby improving work efficiency. The positioning block 5 is provided with two countersunk holes 501, and the bottom plate 1 is provided with a first screw hole 103 corresponding to the countersunk hole 501.

[0037] Among them, three groups of left-right symmetrical second screw holes 301 are opened on the inner side of the rear vertical plate 3. One end of the contour block 6 is provided with a thread and is threadedly connected to the second screw hole 301.

When the chain plate 14 is drilled, the screw rod 701 is rotated in the opposite direction, and the screw rod 701 moves in the opposite direction along the axial direction under the action of the screw sleeve 702, thereby pulling the split flange 703 and the first flange 8 to move outward, so as to take out the processed chain plate 14. By inserting the force rod into the force rod hole 704 and then rotating the force rod, the screw 701 can be easily driven to rotate, saving manpower.
