Embodiment Construction

[0017] Such as figure 1 As shown, a portable differential reaming device includes a motor 1, a first positioning plate 8, a second positioning plate 5, a differential feed mechanism 6, a reamer 7, a coupling 3 and a guide sleeve 9. The motor 1 uses a micro motor with a planetary reducer, which is relatively small in size and meets the installation requirements in a limited space. The motor 1 is fixed to the first positioning plate 8 through the motor guide bracket 2 to fix the position of the motor 1. The output shaft of the motor 1 is connected to the reamer 7 through the coupling 3 to realize torque transmission. The guide sleeve 9 is sleeved at one end of the reamer 7 connected with the coupling 3, which can play a certain guiding role when inserting the knife to avoid the position of the machining aperture due to the end deflection during machining deviation. The differential feed mechanism 6 is composed of a set of sleeves with threads both inside and outside. The diffe...

Abstract

The invention discloses a portable differential reaming device which comprises a motor, a first positioning plate, a second positioning plate, a differential feeding mechanism, a reamer, a coupler and a guide sleeve. The portable differential reaming device is characterized in that the motor and the first positioning plate are fixed through a motor guide support, an output shaft of the motor is connected with the reamer through the coupler, the end, connected with the coupler, of the reamer is sleeved with the guide sleeve, the differential feeding mechanism is installed on the second positioning plate, and a handle of the reamer is fixed through a bearing and is axially arranged in the differential feeding mechanism. The invention further discloses a using method of the portable differential reaming device. The portable differential reaming device has the advantages that the structure is compact, installation is convenient, chambering and reaming can be achieved in a narrow space, the size precision and the surface machining quality of a positioning pin hole can be greatly improved, and therefore the assembly precision of flange connection type products is ensured.

Description

Technical field [0001] The invention relates to a mechanical processing device, in particular to a portable differential reaming device and a method of use thereof. Background technique [0002] Reaming is one of the finishing methods of holes and is widely used in the machining of products. For smaller holes, reaming is a more economical and practical processing method compared to internal grinding and fine boring. Reaming is a method in which a reamer removes a trace metal layer from the wall of a workpiece hole to improve its dimensional accuracy and hole surface quality. The general processing accuracy can reach IT9~IT7, and the surface roughness Ra value is 0.4μm~1.6μm. [0003] Many products with flange connections require precise positioning during assembly, so high requirements are placed on the processing of positioning pin holes. In order to meet the accuracy requirements, it is often necessary to ream the positioning pin holes in the actual machining process, that is, ...
