Description

Technical Field

[0001] This utility model relates to the technical field of gripping device structure for plastic processing, and in particular to a gripping device for processing structural parts of plastic products. Background Technology

[0002] Plastic processing gripping devices are automated equipment used to grip, transport, and place plastic products during the production process. These devices are widely used in injection molding machines, punch presses, and other equipment, and can improve production efficiency and precision.

[0003] Automatic gripping robots are suitable for equipment such as injection molding machines and punch presses, and come in various models and functions, such as high-speed transfer, handling, and palletizing. In existing plastic processing gripping devices, the mechanical claws are bolted to the conveying and transfer equipment, and the gripping mechanism is driven by a motor to open and close the clamping blocks. This installation and gripping method has several problems: First, the gripping device needs to be disassembled and maintained, requiring frequent bolt removal and installation, which is inconvenient. Second, the clamping blocks on the gripping device lack buffer and anti-slip structures, making it easy for plastic product components to slip due to vibration and shaking. Utility Model Content

An mounting plate 4 is fixedly installed on the upper surface of the splicing base 2. Circular through holes are opened at the four corners of the lower surface of the mounting plate 4. The mounting plate 4, in conjunction with the splicing base 2, makes it easier to disassemble and reassemble the gripping mechanism 1 after the gripping device is installed, which is beneficial for the replacement and maintenance of the gripping device. The clamping blocks 3, in conjunction with the gripping mechanism 1, can better grip and hold the outer side of the plastic product structural parts, gripping the plastic product structural parts more firmly, and preventing the plastic product structural parts from slipping due to vibration and shaking. The gripping mechanism 1 is responsible for automatically opening and closing the clamping blocks 3. The clamping blocks 3 fit more closely to the outer side of the plastic product structural parts, making it easier to hold the plastic product structural parts, and have the functions of anti-slip, shock absorption and buffering.

[0023] In this embodiment, the gripping mechanism 1 includes a motor frame 101, a forward and reverse motor 102, a hexagonal frame 103, a screw 104, a first connector 105, a second connector 106, a third connector 107, a fourth connector 108, and a fifth connector 109.

[0024] In this embodiment, the forward and reverse motor 102 is fixedly installed inside the motor frame 101, the hexagonal frame 103 is fixedly installed on the lower surface of the motor frame 101, and the screw 104 is fixedly connected to the lower end of the drive shaft of the forward and reverse motor 102. The two ends of the screw 104 are respectively inserted into the through holes on the upper and lower surfaces of the hexagonal frame 103, and the forward and reverse motor 102 can drive the screw 104 to rotate in both directions.

[0025] In this embodiment, connector 105 is sleeved on the outside of screw 104, connector 106 is disposed in the through hole in the middle of hexagonal frame 103, connector 107 is movably connected between one end of connector 105 and the upper end of connector 106, connector 108 is sleeved on the outside of the corner fixing post at the lower end of hexagonal frame 103, and connector 109 is movably connected between the lower end of connector 106 and the lower end of connector 108. There are two of each of connectors 106, 107, 108, and 109. When screw 104 rotates forward and backward, causing connector 105 to rise and fall, connector 107 tilts and rises and falls accordingly, connector 106 tilts accordingly, and connectors 108 and 109 tilt subsequently, causing clamping block 3 to perform a clamping action.

[0026] In this embodiment, the splicing base 2 includes a pin outer frame 201, a frustum pin post 202, a telescopic spring 203, and a circular pressure plate 204.

[0027] In this embodiment, the outer frame 201 of the pin is fixedly installed on the lower surface of the mounting plate 4, and the frustum-shaped pin 202 is fixedly installed on the upper surface of the motor outer frame 101. The telescopic spring 203 and the circular pressure plate 204 are both located inside the outer frame 201. The upper end of the frustum-shaped pin 202 is inserted into the inner surface of the outer frame 201. The circular pressure plate 204 is located above the frustum-shaped pin 202, and the telescopic spring 203 is located above the circular pressure plate 204. The upper end of the telescopic spring 203 is fixedly connected to the lower surface of the mounting plate 4, and the lower end of the telescopic spring 203 is fixedly connected to the upper surface of the circular pressure plate 204. When installing the gripping device, the bolts pass through the four corners of the mounting plate 4. The through hole allows the gripping device to be installed on the conveying equipment. When it is necessary to disassemble the gripping mechanism 1, lift the frustum pin 202 upwards to compress the telescopic spring 203 between the circular pressure plate 204 and the mounting plate 4, and then pull the frustum pin 202 outwards so that the frustum pin 202 exits the pin outer frame 201. When reinstalling the gripping mechanism 1 with the frustum pin 202, use a screwdriver to press down the circular pressure plate 204 to compress the telescopic spring 203, and insert the frustum pin 202 into the inside of the pin outer frame 201. Loosen the screwdriver until the frustum pin 202 is fully inserted into the inside of the pin outer frame 201, and then release the frustum pin 202.

[0028] In this embodiment, the clamping block 3 includes an L-shaped clamping block 301, a sponge pad 302, and a rubber pad 303. The L-shaped clamping block 301 is fixedly installed on the lower surface of the fifth connector 109. The sponge pad 302 is fixedly installed inside the L-shaped clamping block 301. The rubber pad 303 is fixedly installed on the surface of the sponge pad 302. The surface of the rubber pad 303 has several transverse grooves. The transverse grooves on the surface of the rubber pad 303 are evenly distributed. When the L-shaped clamping block 301 clamps the plastic product structure through the sponge pad 302 and the rubber pad 303, the sponge pad 302 makes the rubber pad 303 fit more closely to the surface of the plastic product structure. The rubber pad 303 plays an anti-slip role, the sponge pad 302 plays a shock absorption and cushioning role, and the transverse grooves on the surface of the rubber pad 303 play a role in increasing friction.
