Description

Grinder with guided assembly function

The present invention relates to a grinder, and more particularly to a grinder having a guiding assembly function.

Referring to FIG. 1, a grinder 1 is taken as an example, and mainly includes a body 11 and a cylinder block 12. The body 11 has an inner annular surface 112 and a bottom wall surface 113 surrounding an axis X and defining a gas chamber 111. An air inlet 114 for guiding airflow into the air chamber 111 is formed on the bottom wall surface 113 and adjacent thereto. A recess 115 of the inner annular surface 112. The cylinder block 12 has a cylinder 121 mounted on the air chamber 111 along the axis X, an air inlet 122 formed in the cylinder 121, and a gasket 123 mounted on an outer surface of the cylinder 121 around the air inlet 122, and A spring pin 124 mounted on one end of the cylinder 121.

When assembling, the relative position of the spring pin 124 to the concave hole 115 of the body is first visually observed, and then the cylinder group 12 is installed into the air chamber 111 along the axis X direction, and the axis X is rotated around the axis X. After the cylinder pin 12 is inserted into the recessed hole 115, the cylinder block 12 is positioned, and the air inlet 122 can be opposed to the air inlet 114, and the air inlet 114 can be blocked. The gasket 123 between the air inlets 122 achieves an airtight effect, and the airflow enters the cylinder 121 through the air inlet 122 from the air inlet 114.

However, when the cylinder 121 blocks the line of sight and blocks the recessed hole 115 and the spring pin 124, the spring pin 124 and the actual position of the recessed hole 115 cannot be accurately known, and the cylinder 121 must be mounted to the cylinder 121. The bottom wall surface 113 and the adjustment method of rotating the cylinder 121 can be accurately The positioning is not only easy to damage the bottom wall surface 113, but also causes trouble and inconvenience in installation.

Therefore, the object of the present invention is to provide a grinding machine having a guiding assembly function capable of improving assembly accuracy and convenience.

Therefore, the grinding machine with the guiding assembly function of the present invention comprises a body, a cylinder, and a guiding unit. The body has an inner annular surface surrounding an axis and defining an air chamber, and an air inlet for guiding airflow. The cylinder is mounted to the plenum along the axis and has an air inlet formed on an outer surface opposite the air inlet. The guiding unit has a groove formed in one of the inner ring surface of the body and the outer surface of the cylinder and extending along the axial direction, and a ring formed on the inner surface of the body and the outer surface of the cylinder. And a guiding portion that slides with the groove.

The utility model has the beneficial effects that the positioning indicator is formed by the protruding guiding portion, and the cylinder is guided to be smoothly installed to the air chamber and the positioning is completed in the case where the guiding portion is aligned with the groove, thereby improving assembly. Accuracy and convenience.

The foregoing and other technical aspects, features and advantages of the present invention will be apparent from the following description of the preferred embodiments.

Referring to Figures 2, 3, and 4, a first preferred embodiment of the present invention having a guide assembly function includes a body 2, a cylinder 3, and a guide unit 4.

The body 2 has an inner annular surface 21 surrounding an axis X, a bottom wall surface 22 perpendicular to the axis X and defining an air chamber 20 together with the inner annular surface 21, and an air inlet 23 for guiding airflow into, and A recess 24 is formed in the bottom wall surface 22 adjacent to the inner annular surface 21.

The cylinder 3 is mounted on the air chamber 20 along the axis X, and has an air inlet 31 formed on an outer surface opposite to the air inlet 23, and a socket 32 formed on an end surface (see FIG. 4), and A positioning member 33 is mounted on the insertion hole 32 and inserted into the recessed hole 24. In the preferred embodiment, the positioning member 33 is a spring pin that is mounted on the insertion hole 32 and is inserted into the recessed hole 24.

The guiding unit 4 has a groove 41 formed in the inner ring surface 21 of the body 2 and extending along the axis X direction with respect to the air inlet 23, and is formed on the outer surface of the cylinder 3 along the axis X with respect to the air inlet 31. A slot 42 extending in the direction and a choke pad 43 interposed between the slot 42 and the recess 41. The choke pad 43 has a ring pad 432 defining a hole 431 and surrounding the air inlet 23 and the air inlet 31. The ring pad 432 is also used as a guide portion in the preferred embodiment and is referred to as a guide portion 432 as described below.

When assembling, the choke pad 43 is first embedded in the recess 42 of the cylinder 3, so that the guiding portion 432 of the choke pad 43 protrudes from the outer surface of the cylinder 3 in the direction perpendicular to the axis X, Therefore, it is only necessary to form the positioning index of the cylinder 3 with the protruding air blocking gasket 43 guiding portion 432 to align the groove 41 of the body 2, thereby guiding the cylinder 3 to be assembled to the air chamber along the axis X. 20, after the positioning member 33 is synchronously inserted into the recessed hole 24, the cylinder 3 is positioned, and the air inlet 31 can be opposed to the air inlet 23, and the air inlet 23 and the inlet can be blocked. The guiding portion 432 between the air ports 31 achieves airtightness As a result, the air flow enters the cylinder 3 through the air inlet 31 through the air inlet 23 and the air passage 431.

Referring to FIG. 5 and FIG. 6 , a second preferred embodiment of the present invention is substantially the same as the first preferred embodiment, except that the guiding unit 4 has an inner ring surface 21 formed on the body 2 and A groove 44 extending in the X direction of the axis, and a convex portion 45 formed on the outer surface of the cylinder 3 as a guiding portion. This convex portion 45 is hereinafter referred to as a guide portion 45.

When assembling, only the guiding portion 45 protruding from the outer surface of the cylinder 3 is aligned with the groove 44 of the body 2, so that the cylinder 3 can be guided to the air chamber 20 along the axis X, to the positioning member 33. After being inserted into the recess 24 in synchronization, the cylinder 3 can be positioned.

According to the above description, the grinding machine with the guiding assembly function of the present invention has the following advantages and effects: the present invention can form the positioning index with the guiding portions 432, 45 protruding from the outer surface of the cylinder 3, and cooperate with the limit guiding. The acting grooves 41, 44 can guide the cylinder 3 to the body 2, are smoothly mounted to the air chamber 20 and are positioned, and the choke pad 43 formed with the guiding portion 432 is also airtight. Therefore, the positioning can be accurately installed at a time, and the cylinder 3 does not need to be rotated in alignment after installation, and the bottom wall surface 22 is not damaged, thereby improving the accuracy and convenience in assembly.

However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification made by the novel patent application scope and the novel description content, Still It is within the scope of this new patent.
