[0030] The following is in conjunction with the appendix Figure 1-8 The present invention will be described in further detail below.

[0031] This utility model discloses a quick-clamping tooling for the reinforcement plate of a scissor lift boom. Example 1

[0032] Reference Figure 1 , Figure 4 , Figure 6 , Figure 8The device includes a clamping shaft 100 and a reinforcing plate 300. The clamping shaft 100 is connected to the processing equipment. One end of the clamping shaft 100 is threadedly connected to a rotating tooling device 200. The rotating tooling device 200 includes a rotating seat 210, a movable clamping assembly 220, and a fixing member 230. By disassembling the fixing member 230 and the movable clamping assembly 220, the reinforcing plate 300 can be freely installed on the clamping shaft 100 and the rotating seat 210. The reinforcing plate 300 is sleeved inside the rotating seat 210. The movable clamping assembly 220 is snapped onto the outer surface of the reinforcing plate 300 by the fixing member 230. The reinforcing plate 300 has a through hole for easy sleeve on the clamping shaft 100. The through hole may be concentric with the reinforcing plate 300, forming a concentric reinforcing plate 300, or the center of the through hole may be different from the center of the reinforcing plate 300, forming an off-center reinforcing plate 300.

[0033] Reference Figure 7 The rotary seat 210 has a sliding groove and a threaded groove 213 inside. The threaded groove 213 is connected to the inside of the sliding groove. The slider slides inside the sliding groove. The internal hex bolt passes through the slider and is threaded into the inside of the threaded groove 213. When the hex bolt is tightened, the slider is locked onto one side of the concentric reinforcing plate 300, thereby performing precision machining on the concentric reinforcing plate 300. When the concentric reinforcing plate 300 needs to be replaced, simply loosen the internal hex bolt to replace the concentric reinforcing plate 300. When the eccentric reinforcing plate 300 needs to be replaced, simply turn the rotary seat 210, causing the rotary seat 210, along with the movable clamping assembly 220 and the fixing piece 230, to simultaneously disengage from the clamping shaft 100.

[0034] Reference Figure 6 , Figure 7 The movable clamping assembly 220 includes a slider, the slider having a through hole inside, and the outer surface of the slider being slidably connected to the inside of the rotating seat 210.

[0035] Reference Figure 6 , Figure 8 The fastener 230 includes an internal hex bolt, which passes through a through hole and is threaded into the inside of a threaded groove 213. The outer surface of the slider is engaged with the outer surface of the reinforcing plate 300.

[0036] The rotating tooling device 200 also includes a retainer 240. The reinforcing plate 300 has a frustum hole inside. When the reinforcing plate 300 does not have a cylindrical hole inside, the retainer 240 is used to further fix the interior of the reinforcing plate 300. The internal thread of the retainer 240 is connected to one end of the clamping shaft 100, and the outer surface of the retainer 240 is engaged with the interior of the frustum hole.

[0037] The implementation principle of the quick-clamping tooling for the scissor lift boom reinforcement plate in Embodiment 1 of this utility model is as follows:

[0038] After tightening the hex bolt, the slider is locked onto one side of the concentric reinforcing plate 300, thereby performing precision machining on the concentric reinforcing plate 300. When the concentric reinforcing plate 300 needs to be replaced, simply loosen the hex bolt to replace it. When the eccentric reinforcing plate 300 needs to be replaced, directly turn the rotating seat 210, causing the rotating seat 210, along with the movable clamping assembly 220 and the fixing piece 230, to simultaneously disengage from the clamping shaft 100. Example 2

[0039] Reference Figure 1 , Figure 2 , Figure 4 A partition plate 211 is fixedly connected to one side of the rotating seat 210. A protrusion 212 is fixedly connected to the outer surface of the partition plate 211. A threaded groove 214 is opened inside the protrusion 212. By tightening the hexagonal bolt 2, which passes through the concave block 221 and is threaded into the threaded groove 214, the eccentric reinforcing plate 300 is locked inside the rotating seat 210 through the cooperation of the two concave blocks 221. When the eccentric reinforcing plate 300 needs to be replaced, the hexagonal bolt 2 is loosened, and the concave block 221 can be pulled outward to loosen the eccentric reinforcing plate 300. The original eccentric reinforcing plate 300 can be removed and replaced with a new eccentric reinforcing plate 300. If the concentric reinforcing plate 300 is to be replaced, the rotating seat 210 can be turned to remove and replace the entire rotating seat 210, movable clamping assembly 220, fixing part 230 and eccentric reinforcing plate 300.

[0040] Reference Figure 1 , Figure 2 , Figure 3 The movable clamping assembly 220 includes two concave blocks 221. The reinforcing plate 300 is placed around the concave blocks 221. After locking the concave blocks 221, the reinforcing plate 300 is clamped in the two concave blocks 221. Both concave blocks 221 are provided with through holes 2. Both protrusions 212 are slidably connected to the interior of the corresponding through holes 2.

[0041] Reference Figure 1 , Figure 2 , Figure 3 The fastener 230 includes two hexagon socket head cap screws, which pass through corresponding through holes and are threaded into the inside of the threaded groove 214. The two concave blocks 221 are both snapped onto the outer surface of the reinforcing plate 300.

[0042] Reference Figure 2 , Figure 5 , Figure 6 The rotating tooling device 200 also includes a retainer 240. The reinforcing plate 300 has a frustum hole inside. The internal thread of the retainer 240 is connected to one end of the clamping shaft 100. The outer surface of the retainer 240 is engaged with the inside of the frustum hole. The outer periphery of the retainer 240 can also be made of rubber to enhance the engagement and fixation.

[0043] The implementation principle of the quick-clamping tooling for the scissor lift boom reinforcement plate in Embodiment 2 of this utility model is as follows:

[0044] Tighten the hex bolt 2 through the concave block 221 and thread it into the threaded groove 214. The two concave blocks 221 work together to lock the eccentric reinforcing plate 300 inside the rotating seat 210. When the eccentric reinforcing plate 300 needs to be replaced, loosen the hex bolt 2 and pull the concave block 221 outward to loosen the eccentric reinforcing plate 300. Remove the original eccentric reinforcing plate 300 and replace it with a new one. If the concentric reinforcing plate 300 needs to be replaced, the rotating seat 210 can be turned to remove and replace the rotating seat 210, the movable clamping assembly 220, the fixing part 230 and the eccentric reinforcing plate 300.

[0045] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
