Description

Pressing head

Technical Field

The utility model belongs to the field of press mounting, relates to a press mounting technology of a sealing cap, and particularly relates to a pressure head.

Background

The sealing caps are required to be pressed in the assembly process of parts such as an automobile gearbox, a power takeoff, a flywheel and the like, generally, the sealing caps are adsorbed by only independently applying a vacuum negative pressure technology for pressing, the sealing cap pressing process is applied in the automobile industry in a large quantity, but the situation that the sealing caps frequently drop in the pressing process is caused by unstable negative pressure generated by a vacuumizing generator and the difference of the sealing caps, and once the sealing caps drop, poor pressing or halt can be caused to cause unnecessary loss. It is therefore necessary to seek a means to avoid this.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art, and provides a pressure head which avoids the falling of parts caused by poor flatness, unstable vacuum negative pressure, equipment failure reset and the like of the parts in the press mounting process of the parts.

The technical scheme adopted by the utility model for solving the technical problem is as follows:

a negative pressure channel is coaxially arranged in the center of the pressure head, the negative pressure channel is connected with an air pipe at the first end of the pressure head, the air pipe is connected with a vacuum generator, the vacuum generator is connected with a PLC control system, a magnet block is embedded in the center of the second end of the pressure head, a through hole is formed in the center of the magnet block, and the through hole is communicated with the negative pressure channel of the pressure head.

And the embedding is that a counter bore is arranged at the center of the second end of the pressure head, and the magnet block is embedded in the counter bore.

Moreover, the outer end face of the magnet block is flush with the end face of the indenter.

And the magnet block is in interference fit with the counter bore.

The utility model has the advantages and positive effects that:

1. the sealing cap can be prevented from falling off due to vibration in the press fitting process due to the attraction of the magnet.

2. The sealing cap can not fall off due to the attraction of the magnet when the vacuum adsorption is lost after the equipment is reset due to the fault.

3. The counter bore magnet structure does not affect the formation of vacuum negative pressure.

4. The vacuum negative pressure can also be used for judging whether the sealing cap is placed as an auxiliary adsorption means, so that the press fitting is prevented when the sealing cap is not placed on the pressure head.

Detailed Description

The present invention is further illustrated by the following specific examples, which are intended to be illustrative, not limiting and are not intended to limit the scope of the utility model.

A pressure head is characterized in that a negative pressure passage 3 is coaxially arranged in the center of the pressure head 1, the negative pressure passage 3 is connected with an air pipe at the first end of the pressure head 1, the air pipe is connected with a vacuum generator, and the vacuum generator is connected with a PLC control system.

The innovation points of the utility model are as follows: a magnet block 2 is embedded in the center of the second end 101 of the pressure head 1, and a through hole is formed in the center of the magnet block 2 and communicated with the negative pressure passage 3 of the pressure head 1.

The embedding is that a counter bore is arranged at the center of the second end 101 of the pressure head 1, and the magnet block 2 is embedded in the counter bore. The outer end face of the magnet block 2 is flush with the end face of the pressure head 1. Magnet piece 2 and counter bore interference fit to the suction that forms will be greater than far away to the suction that produces the sealing cap, just so can guarantee that the pressure head 1 can not deviate from to magnet after the pressure equipment is accomplished.

When the pressed parts are placed in place, a PLC system triggers a signal to start a vacuum generator to form negative pressure, at the moment, a sealing cap is placed on the pressure head 1 by a worker or a manipulator, the sealing cap can be stably fixed on the pressure head 1 under the magnetic property of a magnet and the auxiliary adsorption action of vacuum negative pressure, after the negative pressure reaches a set value, the PLC sends a press-fitting allowing signal and starts to start the press-fitting, and after the press-fitting is finished, the equipment recovers the original point and prepares for the next cycle of press-fitting.

The utility model is on the basis of the traditional negative pressure adsorption sealing cap formed by vacuumizing, the magnet block 2 with a hole in the center is added on the pressure head 1, thus the original vacuum negative pressure is not damaged to identify whether the sealing cap is placed or not, the magnetic adsorption sealing cap of the magnet can be used for ensuring that the sealing cap does not fall off, the structure can fundamentally solve the problem that the sealing cap accidentally falls off, and the utility model is helpful for saving the cost and improving the production efficiency.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the spirit of the utility model, and these changes and modifications are all within the scope of the present invention.
