Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a metal shaft surface grinding device. Background Art

[0002] Metal shafts are used as raw materials for processing various shaft parts. After the metal shafts are cut and other processing processes, the end faces and outer walls of the metal shafts need to be polished. Grinding can avoid unevenness or burrs on the end faces of the shafts, and can also remove rust stains on the surface of the shafts, thereby facilitating subsequent processing. Most of the existing polishing methods are manual handheld grinding wheels. Since the outer edge of the grinding wheel is convex, when polishing the metal shaft, the slightest carelessness will lead to excessive polishing of the metal shaft, and even cause depressions on the surface of the metal shaft. Therefore, a metal shaft surface polishing device is designed to solve the above problems. Utility Model Content

One end of the connecting rod 7 is hinged to the outer edge of the eccentric wheel 6, and the other end of the connecting rod 7 is hinged to the middle of the bottom horizontal limb 22 of the grinding frame 2.

[0020] The outer wall grinding assembly 3 includes a gas rod 31, a guide rod 32 and a grinding block 33, the gas rod 31 is fixedly connected to the vertical limb 21 of the grinding frame 2, the telescopic end of the gas rod 31 is fixedly connected to the middle of the grinding block 33, the two sides of the grinding block 33 are fixedly connected with the guide rod 32, the guide rod 32 is slidably connected to the vertical limb 21 of the grinding frame 2, and the axis of the guide rod 32 is perpendicular to the axis of the positioning flange 5;

[0021] The end surface grinding assembly 4 includes a grinding head 41, a sliding rod 42 and a spring 43. The sliding rod 42 is axially slidably connected to the middle of the top horizontal limb 22 of the grinding frame 2. The bottom of the sliding rod 42 is provided with a grinding head 41. The spring 43 is arranged between the grinding head 41 and the top horizontal limb 22 of the grinding frame 2. The spring 43 forces the grinding head 41 to move toward the box-shaped base 1. The axis of the sliding rod 42 is colinear with the axis of the positioning flange 5.

[0022] The positioning flange 5 includes a base 51, a locking screw 52 and a positioning block 53. The base 51 is rotatably connected to the center of the top end surface of the box-shaped base 1. The bottom end of the base 51 is fixedly connected to the output shaft of the rotating motor 9. The top end of the base 51 is slidably connected to symmetrically arranged positioning blocks 53 on both sides. The locking screw 52 is rotatably connected to the middle of the base 51. The locking screw 52 has a first threaded portion 521 and a second threaded portion 522 on both sides. The first threaded portion 521 is engaged with the positioning block 53 on one side, and the second threaded portion 522 is engaged with the positioning block 53 on the other side.

[0023] The first threaded portion 521 and the second threaded portion 522 of the locking screw 52 have opposite thread directions, and when the locking screw 52 rotates, the positioning blocks 53 on both sides are driven to move closer to or away from each other.

[0024] The contact surfaces of the two positioning blocks 53 also have semicircular grooves 54 for clamping and positioning the metal shaft;

[0025] Through the above settings, in the actual working process, its specific working principle is as follows:

[0026] First, place the metal shaft between the two positioning blocks 53 of the positioning flange 5, and then use a tool to rotate the locking screw 52, ​​which drives the positioning blocks 53 on both sides to move closer to each other until the positioning blocks 53 on both sides clamp the metal shaft through the semicircular grooves 54. When the metal shaft is clamped, the gas rod 31 in the outer wall grinding assembly 3 is started to extend, and the gas rod 31 drives the grinding block 33 to fit the outer wall of the metal shaft;

[0027] After completing the above preparations, start the reciprocating motor 8 and the rotating motor 9. The rotating motor 9 drives the metal shaft to rotate through the positioning flange 5, so that the grinding blocks 33 on both sides grind the outer wall of the metal shaft. During the rotation of the reciprocating motor 8, the grinding frame 2 is driven to reciprocate vertically through the eccentric wheel 6 and the connecting rod 7. During the vertical reciprocating movement of the grinding frame 2, the grinding blocks 33 on both sides move along the axial direction of the metal shaft, thereby preventing the grinding transition of the local area. During the movement of the grinding frame 2 from the top to the bottom, the grinding head 41 located at the top of the grinding frame 2 touches the end face of the metal shaft, and the spring 43 arranged between the grinding head 41 and the horizontal limb 22 of the grinding frame 2 is compressed, so that one end face of the metal shaft rubs against the grinding head 41 during the rotation process for grinding.

[0028] After the above grinding process is completed, the metal shaft is turned around and ground again, so that both end surfaces and the outer wall of the entire metal shaft can be ground;
