Abstract

The utility model relates to a frame marking machine clamping type machine head, which comprises an engraving needle head, wherein the engraving needle head is arranged in a needle head protection frame, and an electromagnet is arranged on the needle head protection frame; the upper side and the lower side of the needle head protection frame are respectively provided with a rotary cylinder. An upper rotary cylinder and a lower rotary cylinder are added on the basis of an original frame marking machine 4 electromagnet adsorption mode to serve as auxiliary clamping. Specifically, a two-position five-way manual valve is adopted for cylinder control, the cylinder is a rotary cylinder and is in a parallel state with a frame when the manual valve is not operated and clamped, and after the manual valve is pulled, the rotary cylinder rotates for 90 degrees and retracts to play a role in clamping the frame surface.

Description

Clamping type machine head of frame marking machine

Technical Field

The utility model belongs to manufacturing system-car assembly process and equipment facility field, concretely relates to frame marker clamp formula aircraft nose.

Background

The general assembly N workshop of the existing enterprise is produced in a mixed line mode, the types of the produced light trucks are various, the types of the corresponding frames are also very many, and each frame is marked with a vehicle identification code (VIN code) at an appointed position. However, only 1 vehicle frame marking machine is needed in the N workshop, and all vehicle frame VIN code imprints need to be adapted. Therefore, the engraving stability of the frame marking machine is important. At present, a frame marking machine is fixed on a frame in a working mode that 4 electromagnets are adsorbed on a VIN code imprinting surface of the frame, and then VIN code imprinting is carried out through an imprinting needle head, which is shown in the attached figure 1 of the specification.

However, the VIN code imprinting surface of the vehicle frame cannot be ensured to be on the same plane due to the limitation of the production process conditions of the vehicle frame. Therefore, the frame marking machine adopting electromagnet adsorption can not ensure that 4 electromagnets are firmly adsorbed on the frame imprinting surface when being suitable for all frame imprinting, so that the problems of VIN code body dislocation deformation, different depths and the like can be caused in the VIN code imprinting process.

It is necessary to design an additional auxiliary clamping means to ensure clamping reliability.

SUMMERY OF THE UTILITY MODEL

The problems that font dislocation deformation, different depths and the like are caused when vehicle frame VIN codes are engraved due to the fact that the mode that an electromagnet of a vehicle frame marker adsorbs a vehicle frame to be fixed cannot adapt to production of all vehicle types in an N workshop are solved. The utility model provides a frame marker clamp formula aircraft nose, concrete technical scheme is as follows:

a clamping machine head of a frame marking machine comprises an engraving needle head, wherein the engraving needle head is arranged in a needle head protection frame, and an electromagnet is arranged on the needle head protection frame; the upper side and the lower side of the needle head protection frame are respectively provided with a rotary cylinder.

Furthermore, four electromagnets are arranged and distributed around the needle head protection frame and correspond to the surface of the frame.

Furthermore, the rotary cylinder is controlled by a two-position five-way manual valve.

An upper rotary cylinder and a lower rotary cylinder are added on the basis of an original frame marking machine 4 electromagnet adsorption mode to serve as auxiliary clamping. Specifically, a two-position five-way manual valve is adopted for cylinder control, the cylinder is a rotary cylinder and is in a parallel state with a frame when the manual valve is not operated and clamped, and after the manual valve is pulled, the rotary cylinder rotates for 90 degrees and retracts to play a role in clamping the frame surface.

The beneficial effects of the utility model reside in that: an auxiliary clamping device is additionally designed to ensure the reliability of the working clamping of the frame marking machine.

Detailed Description

The present invention will be described in detail with reference to the attached drawing 2

A clamping type machine head of a frame marking machine is disclosed, wherein a clamping type machine head 2 comprises an engraving needle 23, the engraving needle 23 is arranged in a needle head protection frame 22, and an electromagnet 21 is arranged on the needle head protection frame 22; a rotary cylinder 24 is provided on each of the upper and lower sides of the needle guard 22. The number of the electromagnets 21 is four, and the electromagnets are distributed around the needle head protection frame 22 and correspond to the surface of the frame. The rotary cylinder 24 is controlled by a two-position five-way manual valve.

The utility model discloses a manual valve of two-position five-way carries out cylinder control, and the cylinder is revolving cylinder, and the time is tight when not acting clamp is with frame parallel state, behind stirring manual valve, revolving cylinder is rotatory 90 degrees and withdrawal to play the effect of tight frame face of clamp.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
