Problems solved by technology

However, due to the high-speed rotation of the reamer during the working process, a large amount of chips and wear heat are generated, and the surface temperature of the molded workpiece is too high to cause deformation, which affects the machining accuracy of the workpiece.

Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment example, the present invention will be further described:

[0016] Such as figure 1 A high-precision vertical oil-injection diamond reamer shown includes a reamer rod 5, a reamer rod sleeve 6 connected to the rear of the reamer rod 5, and a reamer sleeve set in the middle of the reamer rod 5 3. The taper rod 8 arranged inside the reamer rod 5 and the reamer rod sleeve 6. Specifically:

[0017] The front part of the reamer bar 5 is covered with a leading guide sleeve 2; the front end of the reamer bar 5 is provided with an adjusting nut 1; the middle part of the reamer bar 5 is provided with a groove, and the reamer sleeve 3 is set in the groove. Because the inside of the reamer sleeve 3 is manufactured in a cylindrical shape, the versatility is strong, and the reamer sleeve 3 with wear, different particle sizes or different sizes can be replaced at any time according to the needs, which greatly saves...

Abstract

A high-precision vertical oil-injecting diamond reamer, comprising a reamer rod (5), a reamer rod female connector (6) connected to the rear of the reamer rod (5), a reamer sleeve (3) sleeved in the middle of the reamer rod (5), and a tapered pushrod (8) disposed inside the reamer rod (5) and the reamer rod female connector (6); a wedge block (4) is disposed between the canted surface of the tapered pushrod (8) and the reamer sleeve (3); when the tapered pushrod (8) moves forward, the wedge block (4) expands radially along the reamer sleeve (3); the reamer rod female connector (6) is provided with an oil inlet hole (60) thereon; the reamer rod (5) and the reamer sleeve (3) are respectively provided with an oil outlet hole; and honing oil enters the oil inlet hole (60), passes through the reamer rod female connector (6) and the inside of the reamer rod (5), and flows out of the oil outlet hole. The above structure is novel and compact, has a long guide portion, introduces honing oil from the reamer rod female connector (6), and ejects the oil out of the oil outlet holes on the reamer rod (5) and the reamer sleeve (3), thus quickly removes cutting and abrasion heat, reducing workpiece deformation, and increasing surface roughness.

Description

technical field [0001] The invention relates to a high-precision vertical oil-injection diamond reamer. Background technique [0002] Reamer A rotating tool with one or more teeth that removes thin layers of metal from the surface of a machined hole. It is a rotary finishing tool with a straight edge or a helical edge, which is used for reaming or repairing holes. Due to the small amount of cutting, the machining accuracy requirement is usually higher than that of a drill bit, and it can be operated manually or installed on a drilling machine. However, due to the high-speed rotation of the reamer during the working process, a large amount of chips and wear heat are generated, and the surface temperature of the molded workpiece is too high to cause deformation, which affects the machining accuracy of the workpiece. Contents of the invention [0003] The object of the present invention is to provide a high-precision vertical oil-injection diamond reamer. [0004] In order ...
