[Detailed description of the device]

[0001]

[Industrial applications]

 The outer peripheral surface of a cylindrical member such as a mixing tap for assembling water, which is particularly required to be plated with a small cast part, is uniformly ground to streamline the grinding work and perform uniform grinding.

[0002]

[Prior art]

 Most of the mixing tap parts for waterworks are constructed by assembling cast parts with good heat conduction such as true casting, and are plated. By the way, such cast parts have an extremely wide variety of structures, and the threads and joints are machined by machining, but other outer surfaces are generally ground by hand. That is, the outer surface is generally ground by a subcontractor of a town factory, and the actual situation is that the worker grinds one polishing device while holding the parts while pressing them. Therefore, the heat generated by grinding becomes high, making it difficult to hold the ground parts by hand, the cost also rises, and the finish is not uniform.

[0003]

[Problems to be solved by the device]

 From these, there is a demand for a grinding machine that can efficiently and uniformly polish small parts as described above. On the other hand, each part is a cast product and its outer shape is not uniform.Therefore, when polishing, relying on the eyes and feeling while grinding the operator's pressure contact force and the grinding movement speed of the part, etc. There is. In particular, in grinding the outer peripheral surface of the tubular member, the grinding member must be brought into contact with the polishing device at a constant pressure and uniformly rotated. Therefore, training and experience are required, and it is difficult for an amateur. Therefore, the present invention intends to provide a grinding device capable of uniformly grinding a large number of grinding parts regardless of heat generation and capable of grinding the peripheral surface of a cylindrical member while feeling the degree of grinding.

[0004]

[Means for Solving the Problems] A peripheral surface grinding device configured so as to face a grinding wheel of a grinding device in which a polishing cloth is suspended between a wheel and a grinding wheel. It is composed of a movable base that can be manually slid toward the center and a rotating seat that is pivotally supported on the movable base, and a holder for stably holding the grinding member is provided above the rotating seat. At the same time, a manual handle is provided on the rear end side. Also, if the structure of the holder is changed depending on the shape of the grinding member, or if the peripheral surface of the cylindrical member is inclined or eccentric with respect to the axis, the swivel seat is tilted and the guide rail changes the degree of rotation. The inclination can be adjusted accordingly.

The jig 9b is attached to the top of the pivot shaft of the swivel seat 9. The figure shows the jigs to be inserted into the holes formed in the grinding parts, but other suitable jigs may be used if they do not hinder the grinding. For example, one jig 9a may be a singular plurality of jigs that regulate the position of the outer periphery of the grinding component from both sides. In addition, a handle 10 for manual turning is erected at the rear of the turning seat 9 (on the left side in the drawing). If the handle 10 is manually moved in the direction of the arrow in FIG. It is rotated in a plane as shown in.

That is, as shown in FIG. 4, when the grinding part A is supported on the swivel seat 9 and then the handle 12 is operated to move the moving table 8 forward (to the right), the grinding surface Ab of the grinding part A is polished. The cloth 2c is contacted and ground. The degree of this grinding can be visually recognized as the operation pressure feeling of the handle 12, and if the handle 10 is repeatedly moved in the direction of the arrow shown in FIG. The grinding surface Ab of the grinding component A is ground by rotating around 9b as a core. Feeling the degree of grinding and operating the handle 12 to move the movable table 8 backward, the grinding is finished and the grinding part A is removed from the swivel seat 9. Then, in order to grind the grinding surface Abb on the other side, the component A is reversed, replaced with the jig 9b fitted into the hole of the grinding surface Abb, held and ground as described above.

On the other hand, when grinding the top surface Ac of the grinding component A illustrated in FIG. 3, the support jig provided on the upper portion of the swivel seat 9 may be replaced, and FIG. 7 (a side view similar to FIG. 4). 4), the pivot shaft portion of the swivel seat 9 which is pivotally supported on the moving table 8 is arranged so as to be at the center position of the grinding top surface Ac, and the bracket 9c is attached to it, as shown in FIG. The jig 9a as described above is attached. On the other hand, the other jig 9b is a concave jig 9d with which the grinding peripheral surface Ab fits, and the attachment / detachment of the grinding component A is performed by retreating the moving base 8 and turning the turning seat 9 to either one. Remove and replace. Then, the grinding is performed in the same manner as in the above example.

On the other hand, when grinding a grinding part B as shown in FIG. 8 (conceptual drawing), the supporting jigs provided on the swivel seat 9 may be jigs 9a and 9b orthogonal to each other. In order to do this, it is necessary to move the jig 9a up and down. In order to satisfy this, as an example of means corresponding to various grinding parts, it is configured as shown in FIG. 9 (side view) and FIG. 10 (left side view of FIG. 9). That is, the horizontal insertion jig 9a may be moved up and down. In the figure, the slide bracket 13 is mounted on the swivel seat 9, and the lift seat 14 is mounted on the bracket 13 via the slides 14a, 14a. A shaft support portion is formed at the center of the top of the lift seat 14 and the shaft 14b is attached thereto. On the other hand, a cam 15 is loosely supported on the shaft 14b, and a handle 15a is provided on the cam 15 so that the cam 15 can be manually rotated. It is configured to abut the top surface of the ket 13. Therefore, in the case of FIG. 10, the lift seat 14 is lowered and stabilized, and the grinding component B is stably supported in this state, and the top surface Bc is moved by the operation of the handles 12 and 10 as described in FIG. To be ground.

In order to replace and replace the grinding part B, first, the movable table 8 is retracted, and the swivel seat 9 is swung to either one of FIGS. 11 and 12 (both operation explanatory diagrams of FIG. 10). By moving the handle 15a of the cam 15 in the counterclockwise direction as shown in FIG. 5, the lift seat 14 is raised and a part of the grinding component B fitted in 9b is removed and can be replaced. Although the peripheral surfaces of the grinding parts described above were all concentric peripheral surfaces, in the mixed faucet, the peripheral surface formed on the peripheral surface of the mounting screw hole was inclined as shown in Fig. 13 (sketch). Moreover, there is a structure in which the inclination is gradually different along the peripheral surface, or the screw hole is eccentric. In the grinding of the inclined peripheral surface Cb of the grinding component C as described above, the grinding is performed with the following configuration.

That is, a tilting swivel seat 20 as shown in FIG. 14 (partially broken side view corresponding to FIG. 4) and FIG. 15 (partially broken plan view of FIG. 14) is used. The tilting swivel seat 20 has mounting pieces 20a, 20a (one of which is not shown) formed on both sides of the tip end side thereof, and a spindle 19a penetrating the mounting piece 20a and protruding to both sides is mounted. On the other hand, the support shaft 19a is rotatably supported by a support shaft 18 that is inclined forward at the center of the tip of the movable table 8 and is supported by both side projecting seats 19 and 19 of a frame that is pivotally supported. Therefore, the tilting swivel seat 20 can be freely tilted by the support shaft 19a and can be freely swiveled by the support shaft 18.

On the other hand, the inclination of the tilting swivel seat 20 is adapted to change the slanting degree along the top surface of the circular guide rail 21 which is detachably mounted on the mounting seat 22 provided on the moving table 8. As shown in FIG. 15, the guide rail 21 has a semicircular shape that is substantially concentric with the root of the support shaft 18, and the top surface is formed such that one side is higher and the local side is gradually lower. On the other hand, a slider 23 is provided on the lower surface side of the tilting turntable 20 via a bracket 20b, and the slider 23 is arranged along the top surface of the guide rail 21. On the other hand, a manual handle 10 is provided on the rear side of the upper surface of the tilting swivel seat 20, and a supporting device for grinding parts is provided in the central portion. Since the grinding part C of the mixed water faucet shown in FIG. 13 has screw holes penetrating therethrough, the inclined swivel seat 20 should be supported by using a screw rod whose one end is fixed to the swivel seat as the support tool 16. Although shown, other support means may be utilized as the support device.

In grinding, as described above, the moving table 8 is moved to the polishing wheel side by operating the handle 12, and the peripheral surface Cb of the grinding component C is brought into contact with the polishing cloth. Then, when the handle 10 is turned, the inclined and eccentric peripheral surface Cb is ground by the polishing cloth 2c. The swivel seat 20 holds the respective inclinations at the swivel position by the top surface of the guide rail 21, and the peripheral surface of the correct inclination and eccentricity is ground. Further, in order to grind the peripheral surface on the opposite side of the grinding component C, the guide rail 21 is replaced with the one having the opposite inclination, and the grinding component C is also changed in mounting and ground again as described above. Is. If such an inclined revolving seat is used, various inclined peripheral surfaces can be freely ground, and the inclination of the guide rail 21 and the inclined support shaft 18 is adjusted according to the inclined component for grinding.
