Fixture positioning device for electronic fuel injection throttle valve assembly mark printing

Abstract

The invention relates to a fixture positioning device for electronic fuel injection throttle valve assembly mark printing. The fixture positioning device is provided with a special base and a fixture body; the upper end surface of the special base is provided with an arc-shaped groove; a spring knob body is fixed to the arc-shaped groove; a connecting rod is connected with the spring knob body through U-shaped holes; one side of the special base is provided with a dovetail groove; one side of the fixture body is provided with a dovetail boss; the dovetail boss is in matched sleeve connection with the dovetail groove, and is in limiting contact with the upper end surface of the special base through a limiting stopping block on the fixture body, so that the special base can be fixedly connected with the fixture body; and one end of the spring knob body is sleeved with a limiting hole formed in the fixture body, so that the fixture body can be positioned on the special base. According to the fixture positioning device of the invention, the dovetail boss and the dovetail groove are connected with the special base; the fixture body is fixed and positioned through the spring knob body and the limiting stopping block, so that the clamping and replacement of the fixture body are rapider and simpler, and production cost can be saved, and production efficiency can be improved.

Description

Technical field [0001] The invention belongs to the technical field of mark printing tooling equipment, and in particular relates to a clamp positioning device for marking printing of an electric jet throttle assembly. Background technique [0002] When marking and printing text on the EFI throttle assembly, it is necessary to fix and position the EFI throttle assembly printed with the mark. The existing EFI throttle assembly marking and positioning fixtures are all fixed on the special base of the workbench by screws and nuts. If you want to mark and print other types of EFI throttle assemblies, you need to use a screwdriver tool to disassemble and replace The corresponding fixture. In the case of multi-variety mark printing, it is necessary to repeatedly disassemble and assemble the special fixture for positioning the EFI throttle assembly, which takes time and labor, and also affects work efficiency. Therefore, it is necessary to propose improvements. Summary of the inventi...
