Description

TECHNICAL FIELD

[0001] The utility model relates to the field of vacuum chuck, concretely relates to a vacuum chuck grabbing installation fastening device. BACKGROUND

[0002] The bolt connection between the grabbing chuck and the chuck base of the vacuum chuck is inconvenient for installation and maintenance, and professional tools are needed for bolt installation during installation. When the grabbing chuck and the chuck base are installed through the bolt, the screw hole needs to be accurately aligned, and the bolt is difficult to pass through and tighten, which takes a long time. During replacement or maintenance, the bolt needs to be removed, and if the bolt is rusty or stuck, it is more difficult to remove and may damage the surrounding components.

[0003] At the same time, frequent disassembly or continuous vibration generated during equipment operation causes the bolt to gradually loosen. The bolt is a key component for fixing the vacuum chuck. After the bolt loosens, the installation surface between the vacuum chuck and the chuck base does not fit tightly, and gaps appear. This causes air to enter, reduces the vacuum degree, and weakens the adsorption force. At the same time, after the bolt loosens, the fastening force provided by the bolt is insufficient to maintain the connection between the vacuum chuck and the equipment. Under the action of external forces such as work vibration or adsorbed object shaking, the chuck is easy to separate from the equipment, affecting the normal work of the vacuum chuck. SUMMARY

[0004] The utility model discloses a vacuum chuck grabbing installation fastening device to solve the problem of continuous vibration generated during the operation of the existing vacuum chuck, which causes the bolt to gradually loosen, and the fastening force provided by the bolt is insufficient to maintain the connection between the vacuum chuck and the equipment. Under the action of external forces such as work vibration or adsorbed object shaking, the chuck is easy to separate from the equipment.

[0005] The technical scheme of the utility model is:

[0006] A vacuum chuck grabbing installation fastening device, which comprises a grabbing chuck and a chuck base. The grabbing chuck is arranged above the chuck base and fixedly connected between the grabbing chuck and the chuck base. A fastening structure is connected between the grabbing chuck and the chuck base for connecting the grabbing chuck and the chuck base.

[0007] The fastening structure comprises a bottom top plate, a column hole insert, a spring sheet, a locking pin and a hanging rod.

[0008] A group of column hole inserts are vertically connected above the bottom top plate. The column hole inserts are integrally connected with the bottom top plate. The inner part of the column hole inserts is respectively provided with a spring sheet, a locking pin and a hanging rod. The tail of the locking pin is fixedly connected with the spring sheet. The spring sheet is clamped into the hanging rod to fixedly connect the spring sheet and the hanging rod. Locking holes are symmetrically arranged on both sides of the top end of the column hole insert. The locking pin is inserted into the locking hole to fixedly connect the grabbing chuck and the chuck base.

[0009] Further, the bottom of the suction cup seat is provided with a group of mounting holes, symmetrically provided with locking pin positioning holes on the inner wall of the mounting holes, and a locking pin is inserted into the locking pin positioning hole.

[0010] Further, the bottom of the suction cup further comprises a spring sheet pressing structure for mounting and dismounting the fastening structure.

[0011] The spring sheet pressing structure comprises a pressing plate, a pull rod and a pressing block.

[0012] The top of the pressing plate is vertically fixedly connected with a group of pressing blocks, and the bottom of the pressing plate is fixedly connected with the pull rod.

[0013] Further, the top of the pressing plate is flatly attached to the bottom of the bottom top plate on the fastening structure, so that the pressing plate and the bottom top plate are arranged in parallel.

[0014] Further, the pressing block has an arc surface, and the arc surface of the pressing block is in abutment with the outer side slope of the spring sheet, and when the pressing block moves upward along the slope of the spring sheet, the two slopes of the spring sheet move inward.

[0015] Further, the bottom of the suction cup is provided with a group of arc-shaped gripping pads and a group of point-shaped gripping pads, and the group of point-shaped gripping pads are arranged between the group of arc-shaped gripping pads.

[0016] The thickness of the group of arc-shaped gripping pads and the group of point-shaped gripping pads is greater than the thickness of the bottom top plate and the pressing plate.

[0017] Further, the center of the suction cup is provided with an air hole.

[0018] Further, the bottom top plate on the fastening structure is a cross structure, and a circular hole penetrating the air hole is formed in the middle position of the bottom top plate.

[0019] Further, the bottom top plate of the fastening structure is inserted between the group of point-shaped gripping pads.

[0020] Compared with the prior art, the utility model has the following effects:

[0021] When the suction cup and the suction cup seat are installed, the operation is convenient and efficient, without the complicated operation of screwing bolts, nuts and the like as in bolt connection, so that the work efficiency is greatly improved, and the utility model is suitable for automatic production line fast grabbing and carrying work.

[0022] When installing the gripping suction cup and the suction cup base, this utility model only requires the cooperation of the gripping suction cup, the suction cup base, the fastening structure, and the spring plate pressing structure. The fastening structure can quickly install the gripping suction cup and the suction cup base. During the operation of the gripping suction cup, it replaces the traditional bolt connection, which has the disadvantage of bolts gradually loosening due to frequent disassembly or continuous vibration generated during equipment operation, resulting in poor contact between the mounting surfaces of the vacuum suction cup and the suction cup base. The fastening structure can ensure the stability of the connection between the gripping suction cup and the suction cup base.

[0023] This invention inserts the pressure block of the spring plate pressing structure into the column hole insert of the fastening structure. When the pressure block is inserted into the column hole insert, the arc-shaped surface of the pressure block will abut against the inclined surface of the spring plate, so that the pressure plate of the spring plate pressing structure and the bottom plate of the fastening structure are in contact. The spring plate will make the end of the locking pin in the locking hole of the column hole insert, which can quickly complete the separation between the gripping suction cup and the suction cup seat, and facilitate the installation and disassembly of the gripping suction cup and the suction cup seat.
