Efficient template fixture for accurately grinding guide bars

Abstract

The invention discloses an efficient template fixture for accurately grinding guide bars. The efficient template fixture comprises a template (1) and end clamp plates (2). The technical scheme includes that the device comprises the template and the end clamp plates, the template is a rectangular block-shaped steel plate, a plurality of parallel cavity grooves are formed in the template in the left-right directions, and the end clamp plates are arranged at the left end and the right end of the template; a group of guide bar workpieces is inlaid in each cavity groove of the template during application, and each group of guide bar workpieces comprises three guide bar workpieces which are connected with one another in an end-to-end manner and are provided with upward guide grooves; the template is positioned by the aid of angular positioning blocks and is sucked by a magnetic workbench; during operation, the three guide bar workpieces in one cavity groove can be completely ground whenever the workbench of a grinding machine reciprocates once, accordingly, the guide bar workpieces in the various cavity grooves can be accurately ground one by one until all the guide bar workpieces are completely accurately ground, and then a new template provided with guide bar workpieces replaces the template, so that the guide bar workpieces of the new template can be accurately ground. The efficient template fixture has the advantages that shortcomings of low efficiency and high cost in the prior art can be overcome, and purposes of improving guide bar product production efficiency and reducing guide bar product production cost can be achieved.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a high-efficiency die-backing fixture for fine-grinding guide bars used for precision-grinding guide-bar guide grooves. Background technique [0002] The automatic production line of the motor is equipped with an automatic wire embedding machine. The guide bar is an important component that carries and guides the coil winding on the automatic wire embedding machine, and embeds the coil winding into the stator slot; the guide bar is a consumable item that needs to be updated frequently and requires high precision. The consumption is large; the grinding machine needs to be used for grinding in the production and manufacture of the guide bar, especially the guide groove on the guide bar needs to be precisely ground. The precision grinding process has extremely low efficiency and high labor-hour cost. Therefore, the existing technology has problems and shortcomings of low efficiency and high cost...

[0002] The automatic motor production line is equipped with an automatic wire inserting machine. The guide bar is an important part that carries and guides the coil winding on the automatic wire inserting machine, and embeds the coil winding into the stator slot; the guide bar is a consumable product that needs to be updated frequently, and requires high precision. The consumption is large; the grinding machine is required in the manufacture of the guide bar, especially the guide groove on the guide bar needs to be finely ground. Because the shape of the guide bar is slender and complicated, the existing technology adopts one piece The ground precision grinding process has extremely low efficiency and high man-hour cost. Therefore, the existing technology has the problems and deficiencies of low efficiency and high cost
