Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a throwing wheel quick-change structure. Background Art

[0002] Conventional polishing equipment can only be used for one type of polishing wheel and cannot be replaced, making it impossible to verify the economic applicability of the polishing wheel. When different products require different polishing effects, different polishing wheels can only be replaced and used, and they cannot be compatible on the same equipment. Preparing multiple different polishing wheel equipment takes up space and is costly, which is not suitable for mass production of large quantities of parts. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a throwing wheel quick-changing structure, which can meet the needs of throwing wheels with different inner diameters and different sizes, achieve economical and practical verification of throwing wheels, and realize the replacement of different throwing wheels on one device.

[0004] To achieve the above purpose, a polishing wheel quick-changing structure is designed, including a sleeve, a rotating shaft is passed through the sleeve, one end of the rotating shaft is connected to the motor, the other side of the rotating shaft passes through the baffle, a polishing wheel is sleeved on the outside of the rotating shaft, and the polishing wheel is fixed to one end of the rotating shaft through a pressure plate. The rotating shaft consists of a base shaft and a connecting shaft.

[0005] The basic shaft is provided with a concave surface, and the connecting shaft is provided with a convex surface. The concave surface of the basic shaft and the convex surface of the connecting shaft are locked by fastening screws.

[0006] The front end of the basic shaft is provided with a fixed journal.

[0007] The base shaft is provided with a limiting groove matched with the polishing wheel.

[0008] The fixed journal of the basic shaft can be sleeved with a quick-change sleeve 1 or a quick-change sleeve 2.

[0009] Compared with the existing technology, the utility model splits the equipment throwing wheel from a single rotating shaft into a transition shaft and a basic shaft, wherein the basic shaft is a replacement part and can be quickly maintained according to the required processing size or wear condition. At the same time, a ring is provided as a quick-change sleeve to cooperate with the basic shaft to achieve rapid compatibility of throwing wheels with different inner diameters.

DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figures 1 to 4 As shown, a rotating shaft 3 is passed through the sleeve 8, one end of the rotating shaft 3 is connected to the motor 4, and the other side of the rotating shaft 3 passes through the baffle 9. A polishing wheel 2 is sleeved on the outside of the rotating shaft 3. The motor 4 provides driving force to drive the rotating shaft 3 to rotate, and the rotating shaft 3 drives the polishing wheel 2 to rotate so that the polishing wheel 2 can polish the parts. The polishing wheel 2 is fixed to one end of the rotating shaft 3 by the pressure plate 1. The rotating shaft 3 is composed of a base shaft 3.1 and a connecting shaft 3.2.

[0017] The base shaft 3.1 is provided with a concave surface, and the connecting shaft 3.2 is provided with a convex surface. The concave surface of the base shaft 3.1 and the convex surface of the connecting shaft 3.2 are locked by a fastening screw 5. A fixed shaft neck 10 is provided at the front end of the base shaft 3.1, and a limiting groove 11 is provided on the base shaft 3.1 to cooperate with the polishing wheel 2. The outer diameters of the fixed shaft neck 10 and the limiting groove 11 of the base shaft 3.1 are different, and they can play a fixing role respectively, so they can be compatible with two polishing wheels with different inner diameters.

[0018] The fixed journal 10 of the base shaft 3.1 can be fitted with a quick-change sleeve 6 or a quick-change sleeve 2 7. By fitting the quick-change sleeve 1 6 or the quick-change sleeve 2 7 on the fixed journal 10, the outer diameter of the base shaft 3.1 can be changed. The base shaft 3.1 can also be compatible with throwing wheels of other inner diameters.

[0019] The specific installation and working process of the present invention is as follows: insert the basic shaft 3.1 into the top of the connecting shaft 3.2, lock and fix the connecting shaft 3.2 and the basic shaft 3.1 with the fastening screw 5, connect the end of the connecting shaft 3.2 to the motor 4, insert the fixed connecting shaft 3.2 and the basic shaft 3.1 into the sleeve 8 and the baffle 9 in turn, sleeve the polishing wheel 2 on the top of the basic shaft 3.1 and fix the polishing wheel with the pressure plate 1, wherein the basic shaft 3.1 is a replaceable part, and can be quickly disassembled and replaced by loosening the fastening screw 5. Since the stable fixation of the polishing wheel is determined by the inner diameter of the polishing wheel, the outer diameter of the basic shaft 3.1 selected in this utility model is generally compatible with two kinds of polishing wheels. By replacing basic shafts 3.1 with different outer diameters or sleeved with quick-change sleeves with different outer diameters on the basic shaft 3.1, a variety of different polishing wheels can be replaced according to needs. Compared with the original technology, it can simplify the problem of rapid changeover required when the polishing wheel equipment processes different polishing wheels.
