Embodiment Construction
[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0028] Such as Figure 1 to Figure 5 As shown, the broach set of the present invention includes a broach set body, an adjustment pad 6, a wear-resistant plate 8 and an adjustment screw 9. The broach set body is divided into an installation and positioning part 1 and a working part 2 along the axial direction, and the installation and positioning part 1 It includes a rectangular mounting part 11 and a cylindrical positioning part 12. The rectangular mounting part 11 is connected with the working part 2 as a whole through the cylindrical positioning part 12. The broach sleeve can be limited in the circumferential direction through the rectangular mounting part 11. The cylindrical positioning part 12 The outer diameter is larger than the outer diameter of the working part, forming an axial limit end face, which can limit the axial position of the...

Abstract
The invention discloses an adjustable broaching tool sleeve and a manufacturing method thereof. The broaching tool sleeve comprises a broaching tool sleeve body, an adjusting cushion block, an abrasion resisting sheet and an adjusting screw. The broaching tool sleeve body is divided into an installing positioning part and a work part in the axial direction. A broaching tool containing cavity is formed in the center of the broaching tool sleeve body. A broaching tool work area penetrating the side wall of the broaching tool containing cavity is formed through side opening of the work part, anda broaching tool is contained in the broaching tool containing cavity. An inwards-concave adjusting cushion block installing groove is formed in the inner side wall of the broaching tool containing cavity. The top face of the adjusting cushion block and the bottom face of the abrasion resisting sheet are fixed through a dovetail groove structure. The work part is provided with an adjusting screw hole penetrating the bottom of the adjusting cushion block installing groove. The adjusting cushion block is provided with an adjusting hole, the adjusting screw penetrates the adjusting screw hole andpenetrates the adjusting hole, and the front end of the adjusting screw jacks and supports the adjusting cushion block for jacking and supporting limitation of the adjusting cushion block. Through adjustment on the installing depth of the adjusting screw, the adjusting cushion block can be supported to drive the abrasion resisting sheet to ascend and descend in the adjusting cushion block installing groove, and accordingly the abrasion gap between the broaching tool and the abrasion resisting sheet can be adjusted and offset.
Description
technical field [0001] The invention belongs to the technical field of tool accessories, and in particular relates to an adjustable broach sleeve for an electromagnetic valve and a processing method. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetic. There is a guiding chute in the piston hole of the solenoid valve. The precision requirement is relatively high. Now the chute is basically processed by broaching. During the processing, the reciprocating broach needs to pass through the broach The guidance of the sleeve is used to maintain the working stability of the broach and ensure the dimensional accuracy of the solenoid valve hole processing. The existing broach cover is made of No. 45 steel as the raw material. After the blank is heat-treated, it is wire-cut to form the broach guide groove. The surface precision of the broach guide groove is low, so that the contact between the broach and the broach guide groove surface...
