Abstract
The utility model relates to a terrazzo polishing machine and specifically relates to a spherical surface centering device used for a terrazzo polishing machine. The spherical surface centering device used for the terrazzo polishing machine includes a main shaft and a connection plate. The spherical surface centering device used for the terrazzo polishing machine is characterized in that the front end of the main shaft is provided with a bulb; the front end of the bulb is a positioning tangent plane; the center of the positioning tangent plane is provided with an arc-shaped groove; and the center of the connection plate is provided with a structure where the bulb can be installed. By arranging the arc-shaped groove in the center of the tangent plane of the front end of the bulb, a contact area of the bulb and the connection plate is increased and a good positioning effect can be achieved. By adopting the above structure, the spherical surface centering device used for the terrazzo polishing machine has an advantage that positioning errors are reduced.
Description
Technical field
The utility model relates to a kind of terrazzo machine, specifically a kind of terrazzo machine spherical centering device.
Background technology
Terrazzo machine terminal pad, by main shaft spherical centering device, guarantee, when mill work is waved, the link position at main shaft and mill center there will not be large deviation, in prior art, terrazzo machine main shaft centring means is the bulb curved surface of front end, and the bulb sphere of this structure is in long-time use procedure, wear and tear, easily occur deviations.
Summary of the invention
The utility model overcomes the shortcoming of above existence, and a kind of terrazzo machine spherical centering device that is not prone to deviations is provided.
The technical solution of the utility model is achieved in that terrazzo machine spherical centering device, comprise main shaft, terminal pad, it is characterized in that: the front end of main shaft has bulb, described bulb front end is location tangent plane, and described tangent plane center, location has the groove of circular arc, described terminal pad center has the structure that bulb can be installed, the circular groove at the tangent plane center of bulb front end, has increased the contact area of bulb and terminal pad, can better play positioning action.
The beneficial effects of the utility model: the terrazzo machine spherical centering device of this spline structure has advantages of that location is not prone to deviation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, main shaft 2, terminal pad 3, bulb 4, location tangent plane 5, groove.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1: terrazzo machine spherical centering device, comprise main shaft 1, terminal pad 2, it is characterized in that: the front end of main shaft 1 has bulb 3, described bulb 3 front ends are location tangent planes 4, and described location tangent plane 4 centers have the groove 5 of circular arc, and described terminal pad 2 centers have the structure that bulb 3 can be installed, the circular groove 5 at location tangent plane 4 centers of bulb 3 front ends has increased the contact area of bulb 3 with terminal pad 2, can better play positioning action.
The terrazzo machine spherical centering device of this spline structure has advantages of that location is not prone to deviation.
