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

The invention relates to a high-precision vertical internal oil injection diamond reamer which comprises a reamer bar, a reamer bar female connector, a reamer sleeve and a push taper bar, wherein the reamer bar female connector is connected to the rear of the reamer bar, the reamer sleeve is sleeved in the middle of the reamer bar, and the push taper bar is arranged inside the reamer bar and the reamer bar female connector. A wedge block is arranged between an inclined surface of the push taper bar and the reamer sleeve, and radially expands along the reamer sleeve when the push taper bar moves forwards. An oil inlet hole is formed in the reamer bar female connector, oil outlet holes are formed in the reamer bar and the reamer sleeve respectively, and honing oil enters the reamer from the oil inlet hole, passes the insides of the reamer bar female connector and the reamer bar and flows out of the oil outlet holes. The high-precision vertical internal oil injection diamond reamer is novel and compact in structure, a guide position is long, the honing oil led in by the reamer bar female connector is injected from the oil outlet holes in the reamer bar and the reamer sleeve, cutting and wear heat can be rapidly dissipated, deformation of workpieces is decreased, and surface roughness is improved.

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 ...
