Problems solved by technology

Such disadvantages are high maintenance costs and relatively long maintenance cycle, which not only brings high maintenance costs to the company, but also brings downtime losses, etc., and now only a few companies can repair domestic machine tool spindles and send them back to the manufacturer. It only takes one week, the maintenance cycle is about 20 working days, and the repair cycle is one week, so the overall maintenance cycle is also six weeks
It is impossible to repair it by yourself with existing resources, and there is no way to guarantee the accuracy of its spindle

Embodiment Construction

[0033] The design concept of the present invention is to add an angle adjusting device to make the grinding head have the same angle as the taper of the machine tool spindle to be repaired, and then realize the grinding and repairing of the taper hole through the feed of the grinding head along the angle. The design concept of the present invention will be further described in detail below in conjunction with the specific structure description.

[0034] by Figure 1-Figure 5 It can be seen that the mobile machine tool spindle taper hole repair grinder of the present invention includes a base 1, a grinding head 2, a grinding head rotation driving device that fixes the grinding machine on a worktable surface 20, and the grinding head 2 and the grinding head rotation driving device pass through and The two fixed sliding blocks 3 and the supporting plate 4 are connected in cooperation. The horizontal support surface of the base 1 is provided with a connecting half hole 22 connected ...

Abstract

The invention relates to machine tool processing equipment, in particular to a mobile grinding machine for repair of a machine tool spindle. The grinding machine comprises a base (1), a grinding head (2) and a grinding head rotary driving device, wherein the grinding head (2) and the grinding head rotary driving device are in fit connection with a supporting plate (4) through a sliding block (3) which is connected with the grinding head (2) and the grinding head rotary driving device fixedly; a Y-direction moving guide rail (5) which is in fit with the sliding block (3) is arranged on the supporting plate (4) fixedly; the sliding block (3) is driven by a Y-direction feed driving mechanism which is arranged on the supporting plate (4) fixedly to slide along the Y-direction moving guide rail (5); and the supporting plate (4) is rotatably adjusted and connected relative to the base (1) by a rotary fixed device which is arranged between the supporting plate (4) and the base (1). By adoption of the technical scheme, the machine tool spindle can be repaired; the grinding machine is simple in structure; and cost is saved effectively.

Description

Technical field [0001] The invention relates to machine tool processing equipment, and in particular to a mobile machine tool spindle repair grinder. Background technique [0002] The machine tool spindle is an indispensable part of the CNC cutting machine tool. It relies on the spindle servo motor to hold the tool and cut the workpiece. The spindle taper hole is an important part of the connection between the tool and the spindle. If the spindle taper hole is worn or otherwise damaged, runout errors will occur, dynamic balance damage will cause vibration, etc., seriously affecting the service life of the tool and product processing quality. . The wear of the spindle taper hole generally depends on the usage conditions, such as rough machining of the machine tool, high cutting force on the tool, etc., and there are also damages caused by human problems. If the taper hole of the machine tool spindle is damaged, it will cause defects in three aspects: first, the quality of t...
