[0001] The utility model relates to the technical field of non-fired brick production equipment, in particular to a handling fixture manipulator. Background Art

[0002] Concrete block bricks are a kind of building materials with light weight, porous structure, good heat insulation and fire resistance. They have the characteristics of low cost, fast manufacturing speed and light weight, and are one of the more common building materials in the construction industry.

[0003] The production process of concrete blocks includes steps such as batching, mixing, forming, and curing. After the concrete is compacted and formed in the mold, it needs to be separated one by one and stacked for curing; although the blocks are compacted and formed, the concrete has not solidified yet. The existing gripper manipulator grabs the concrete blocks by means of side clamping, which is easy to cause damage and is not very suitable. At present, this process usually adopts manual operation, with high labor intensity and low work efficiency; in order to replace manual operation, a handling fixture manipulator is proposed.

A transverse translation slide rail 102 is installed on the slider of the longitudinal translation slide rail 101. The piston rod of the longitudinal translation cylinder 104 is connected to the transverse translation slide rail 102 to push it to reciprocate along the longitudinal translation slide rail 101.

[0017] Refer to Figure 2 , the handling gripper 2 includes a transverse support plate 201. The transverse support plate 201 is installed on the slider of the transverse translation slide rail 102. The transverse translation motor 3 is installed on the upper surface of the transverse support plate 201. A lifting support plate 202 is arranged below the transverse support plate 201. The transverse support plate 201 and the lifting support plate 202 are connected by a support rod 203. A lifting cylinder 204 is installed on the lifting support plate 202. The lifting cylinder 204 is vertically arranged and its piston rod passes through the lifting support plate 202 and is installed with a clamping support plate 205. A guide rod 206 is installed on the upper surface of the clamping support plate 205. The upper end of the guide rod 206 penetrates through the lifting support plate 202.

[0018] Two clamping cylinders 207 are installed on the upper surface of the clamping support plate 205. The clamping cylinders 207 are vertically arranged, and clamping slide rails 208 are installed on both sides thereof. A connecting rod 209 is arranged between the clamping slide rails 208 and the clamping cylinders 207. The two ends of the connecting rod 209 are respectively hinged to the piston rod of the clamping cylinder 207 and the slider of the clamping slide rail 208. A crank arm 210 is installed on the slider of the clamping slide rail 208. The upper end of the crank arm 210 is connected to the slider of the slide rail 208, and a limiting plate 214 is installed at the lower end. The limiting plate 214 is installed on one side where the two crank arms 210 face each other. A buffer support plate 211, a rotating shaft 212, and a bottom support plate 213 are sequentially installed between the two crank arms 210 from top to bottom. A push plate 215 is installed on one side where the two buffer support plates 211 face each other. A telescopic rod 216 is installed on the push plate 215.

[0019] For the convenience of understanding the present invention, the following combines Figure 1 、 Figure 2 to elaborate in detail on the working principle of this solution:

[0020] During handling, the handling gripper 2 moves above the building block 4. The piston rod of the clamping cylinder 207 retracts, separating the two opposite limiting plates 214. At this time, under the action of the spring 217, the push rod 218 drives the bottom support 219 to retract into the limiting plate 214. The piston rod of the lifting cylinder 204 extends to place the two limiting plates 214 on both sides of the building block 4. The piston rod of the clamping cylinder 207 extends to make the two crank arms 210 approach each other. The push plate 215 contacts the building block 4 before the limiting plate 214. The spring 217 is compressed, and at the same time, the bottom support 219 is driven by the push rod 218 to extend out of the limiting plate 214 and insert under the building block 4 to lift and transport it.

[0021] Compared with the conventional method of gripping building blocks by side clamping, the technical solution of this application does not require the frictional force between the gripper and the side of the building block to offset its gravity during transportation. Therefore, it can avoid the deformation and damage of the concrete building block caused by excessive clamping force before it solidifies, and effectively replaces manual operation, improving production efficiency.
