Description

Punching positioning device for mobile phone sheath

Technical Field

The utility model belongs to the technical field of the technique of cell-phone sheath manufacturing installation and specifically relates to a positioner that punches a hole of cell-phone sheath.

Background

The mobile phone sheath is a protective clothing wrapped on the outer surface of the mobile phone to play a role in decorating and protecting the mobile phone, parts such as an illumination lamp hole and a camera lens of the mobile phone are usually arranged on the back of the mobile phone, and holes are usually formed in the corresponding positions of the mobile phone sheath in order not to influence the functions of illumination, camera shooting and the like of the mobile phone.

In the existing punching process, a mobile phone sheath obtained by injection molding is arranged on a workbench top with a cutter, the cutter on the workbench top is abutted to a position to be punched of the mobile phone sheath, then a punching die above the workbench top falls down and punches at a position corresponding to the cutter to obtain a hole, and then the mobile phone sheath with a camera hole is obtained; before the punching die falls down, a gap exists between the cutter and the mobile phone sheath, the cutter and the mobile phone sheath are not tightly contacted, so that the edge of the opening is not smooth enough, in addition, in the punching process, the punching die touches the mobile phone sheath, the sheath can be horizontally deviated, and the obtained product is not fine enough.

Disclosure of Invention

To the not enough of existence among the above-mentioned prior art, the utility model aims to provide a positioner that punches a hole of cell-phone sheath.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a positioner that punches a hole of cell-phone sheath, includes the base, be provided with the fixed plate on the base, install lift cylinder and a plurality of parallel arrangement's slide rail on the fixed plate, slidable mounting has the slider on the slide rail, be fixed with the mounting bracket on the slider, the cylinder axle end of lift cylinder with the mounting bracket is fixed, be provided with the location cover mould on the mounting bracket, the through-hole has been seted up on the location cover mould, be provided with the bearing post on the base, the top of bearing post is provided with the cutter, the location cover mould passes through the through-hole cover is located outside the cutter.

Furthermore, the positioning sleeve die comprises a first sleeve die and a second sleeve die, the first sleeve die is installed on the installation frame, the second sleeve die is connected with the first sleeve die through a telescopic slide rod, a translation cylinder is arranged on the installation frame, and a cylinder shaft of the translation cylinder is connected with the second sleeve die.

Furthermore, a blanking channel is arranged in the pressure bearing column and is positioned right below the cutter.

Adopt above-mentioned scheme, the beneficial effects of the utility model reside in that: this product can fix the cell-phone sheath through the location cover mould, and the cutter is located the through-hole, and the location cover mould can be along with the mounting bracket lift, and after the cell-phone sheath cover was located on the location cover mould, the decline makes the cutter inconsistent with the position of waiting to cut-off of cell-phone sheath, takes place the displacement when preventing to punch a hole.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

As shown in the accompanying drawings, the punching positioning device for the mobile phone sheath comprises a base 1, wherein a fixed plate 2 is arranged on the base 1, a lifting cylinder 3 and a plurality of sliding rails 4 which are arranged in parallel are arranged on the fixed plate 2, a sliding block 5 is arranged on the sliding rails 4 in a sliding manner, a mounting frame 6 is fixed on the sliding block 5, the tail end of a cylinder shaft of the lifting cylinder 3 is fixed with the mounting frame 6, a positioning sleeve die 7 is arranged on the mounting frame 6, a through hole 8 is formed in the positioning sleeve die 7, a bearing column 9 is arranged on the base 1, a cutter 10 is arranged at the top of the bearing column 9, and the positioning sleeve die 7 is sleeved outside the cutter 10 through the through hole 8.

The positioning sleeve die 7 comprises a first sleeve die 11 and a second sleeve die 12, the first sleeve die 11 is installed on the installation frame 6, the second sleeve die 12 is connected with the first sleeve die 11 through a telescopic slide rod 13, a translation cylinder 14 is arranged on the installation frame 6, and a cylinder shaft of the translation cylinder 14 is connected with the second sleeve die 12.

A blanking channel 15 is arranged in the pressure bearing column 9 and is positioned right below the cutter 10. The punched waste falls from the blanking channel 15.

The working principle is as follows: the positioning sleeve die 7 is used for fixing a mobile phone sheath to be punched, after the mobile phone sheath to be punched is buckled on the positioning sleeve die 7, the translation cylinder 14 is started to enable the second sleeve die 12 to move towards the direction far away from the first sleeve die 11, so that the mobile phone sheath is tensioned, and the mobile phone sheath cannot deviate in a horizontal plane during punching; then, the lifting cylinder is started, so that the mounting frame 6 moves downwards, the mobile phone sheath on the positioning sleeve die 7 is driven to move downwards to be abutted against the cutting edge of the cutter 10, and the cutting edge of the cutter 10 is tightly abutted against the position to be perforated of the mobile phone sheath, so that no deviation occurs, and the perforated edge obtained by a finished product is smoother.

The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
