Background

A conventional electric sander chuck is shown in fig. 1-3 (wherein dimensions irrelevant to the present application are not shown), a head 1 of the existing electric sander chuck is provided with three vertical grooves 3 called three-petal springs, the center of each vertical groove is a hole for clamping sanding tools such as a grinding rod, a tail 2 of the existing electric sander chuck is a cylindrical shaft, the tail of the existing electric sander chuck is matched with a hollow spindle, and the hollow spindle is sleeved in the tail of the existing sander chuck to clamp the head of the existing sander chuck so as to clamp the sanding tools such as the grinding rod. Tail and hollow main shaftThe mating outer surfaces are dimensioned to

The tolerance range is between 0.004, the length of the workpiece is up to 28mm when the workpiece is generally processed by a grinding machine, the processing cost is high, and the longer the length is, the larger the surface taper formed by the grinding machine is, and the more difficult the machining precision is.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of high processing cost and large processing difficulty of the existing electric polisher chuck, and provides an electric polisher chuck which is easy to process and low in processing cost.

The utility model discloses the technical scheme who adopts is an electric grinder chuck, and the cylinder axle that its main points lie in its afterbody comprises the cylinder of the different diameters of three-section, is first to keep away the sky section, the finish grinding section, the second respectively, and the finish grinding section is between first to keep away the sky section, the second keeps away between the sky section, is first to keep away the sky section between finish grinding section and the head, and the size and the hollow spindle of finish grinding section cooperate, and first diameter of keeping away the sky section, the second keeps away the sky section all is less than the finish grinding section.

The utility model discloses an improve on the basis of current electric grinder chuck, keep the basic structure and the size of electric grinder chuck, do not influence matched with spare part and overall structure with it, only redesign the processing section of its afterbody, keep certain length and hollow spindle matched with finish grinding section at its middle part, design its head and the tail into first section of keeping away, the second keeps away the section of keeping away, because first section of keeping away, the second keeps away and does not have the cooperation relation between section of keeping away and the hollow spindle, be less than the finish grinding section again, its surface can not process, the processing degree of difficulty has been reduced, the processing cost has been saved.

Further design: the diameter of the fine grinding section is

The diameters of the first and second avoidance sections are 0.1-0.2mm smaller than that of the fine grinding section. On the basis of saving the processing cost, the strength of the chuck of the electric grinding machine is ensured.

The first and second avoidance sections have the same diameter. Is convenient to manufacture.

The diameter of the first and second avoidance sections is

Because the first and second hollow sections are not matched with the hollow main shaft, the processing precision can be reduced, and the processing cost can be saved.

The axial starting point of the fine grinding section is before the end point of the three vertical grooves of the chuck, and the axial end point is between the end point and the tail end of the three vertical grooves of the chuck.

The total length of the tail part of the chuck of the electric grinding machine is 28mm, the length of the first clearance section is 4-6mm, the length of the fine grinding section is 13-17mm, and the length of the second clearance section is 7-9 mm. The utility model discloses the length that remains the finish grinding section is about the half of original length, considers the front end to the clamp of head tightly, and the first length of keeping away the sky section is less than the second and keeps away the length of sky section.

The utility model discloses change for a short time prior art, remain the basic structure and the size of electric polisher chuck, do not influence matched with spare part and overall structure with it, only redesign the processing section of its afterbody, design out at the surface of electric polisher chuck afterbody first to keep away the sky section, the second keeps away the sky section, and first to keep away the sky section, the second keeps away and does not have the cooperation relation between sky section and the hollow spindle, has reduced the processing degree of difficulty, has saved the processing cost.

Detailed Description

The embodiments illustrated herein will enable those skilled in the art to more fully understand the present invention, without limiting it in any way, when the present invention is described in detail below with reference to the accompanying drawings.

As shown in fig. 4, an electric grinder chuck is improved based on the existing electric grinder chuck, the basic structure and size of the electric grinder chuck are retained, the parts and the whole structure matched with the electric grinder chuck are not affected, only the processing section of the tail part 2 is redesigned, the middle part of the electric grinder chuck is retained with a fine grinding section with a certain length matched with the hollow spindle, the head and the tail of the electric grinder chuck are designed into a first clearance section and a second clearance section, namely, a cylindrical shaft at the tail part of the electric grinder chuck is composed of three cylinders with different diameters, namely, the first clearance section 21, the fine grinding section 22 and the second clearance section 23 are respectively arranged, the fine grinding section is arranged between the first clearance section and the second clearance section, the first clearance section is arranged between the fine grinding section and the head part, the size of the fine grinding section is matched with the hollow spindle, and the diameters of the first clearance section and the second clearance section are smaller than the fine grinding section.
