Description

Technical Field

[0001] The utility model relates to the technical field of PCB text printing industry, and in particular to a linked air clamp lifting mechanism which is convenient for replacing air clamps. Background Art

[0002] The existing pneumatic clamping mechanism consists of several air clamps and cylinders. Each cylinder is responsible for driving the corresponding air clamp to move vertically. Since all air clamps move according to the air clamp movement angle, the air clamps will be unevenly stressed when clamping the plate. One cylinder corresponds to one clamp, resulting in excessive use of cylinders, high costs, and increased failure rates. It will also cause individual cylinders to be out of sync during air supply, and the machine will hit the clamp during operation, causing damage to the equipment. Utility Model Content

[0003] The purpose of the present utility model is to provide a linkage type air clamp lifting mechanism that is convenient for replacing the air clamp in order to solve the above problems, as described below.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The mounting plate is provided with a cylinder for driving the movable plate to move vertically;

[0007] A plurality of air clamps are installed along a straight line on the movable plate.

[0008] The above-mentioned linkage type air clamp lifting mechanism that is convenient for replacing air clamps is used. The mounting plate is installed on the table, and the movable plate is driven vertically by the cylinder. The movable plate can drive all the air clamps to rise and fall at the same time, so that the air clamps cooperate with the upper side of the table to clamp the plate.

[0009] By setting up a movable plate, all the air clamps are at the same level. When clamping the plate, all the air clamps can fit with the upper side of the plate. If the air clamp is damaged or broken, there is no need to separate the mounting plate from the table. The damaged air clamp can be directly rotated to separate it from the movable plate and replaced. If the air clamp is broken inside the connecting block, the connecting block can be removed from the movable plate.

[0010] Preferably, the movable end of the cylinder is fixed to the movable plate.

[0013] Preferably, the air clamp includes a fixing column, the fixing column is threadedly connected to the connecting block, and a fixing plate is fixed to the upper end of the fixing column.

[0014] Preferably, a rubber pad is provided at the bottom of the fixing plate, and a hexagonal groove is provided on the upper side of the fixing plate.

[0015] Preferably, the guide assembly includes several slides, which are vertically fixed on the mounting plate, and a slider is slidingly provided on the surface of the slide, and the slider is fixedly installed on the movable plate. Grooves are provided on both sides of the slide, and convex strips are provided on the opposite surfaces of the slider, and the two convex strips are respectively fitted with the two grooves.

[0019] 1. The movable plate is driven to move vertically by the cylinder, and the movable plate can drive all the air clamps to move up and down at the same time, so that the air clamps cooperate with the upper side of the table to clamp the plate. By setting the movable plate, all the air clamps are at the same level. When clamping the plate, all the air clamps can fit with the upper side of the plate to ensure the uniformity of the force on the plate. Only one cylinder is set to achieve stable driving of the movable plate. Specifically, the number of cylinders can be increased according to the clamping force required. The movable plate carries the air clamps. Compared with the design of a one-to-one matching of the number of air clamps and cylinders, the number of cylinders used can be significantly reduced, thereby reducing costs and reducing equipment failure rate.

[0020] 2. The air clamp is installed on the movable plate by threaded connection. If the air clamp is damaged, there is no need to separate the mounting plate from the table. The damaged air clamp can be directly rotated to separate it from the movable plate and replaced. If the air clamp breaks inside the connecting block, the connecting block can be removed from the movable plate, thereby improving the convenience of maintenance of the mechanism.

[0021] 3. The guide assembly can limit the direction of movement of the movable plate, making the movement of the movable plate more stable and preventing the movable part of the cylinder from being subjected to lateral shear force;
