The scheme is further as follows: the steering connecting rod comprises a pushing arm and a swinging arm, one end of the pushing arm is connected with a sliding sleeve of the lower support adjusting mechanism, the other end of the pushing arm is connected with the lower support, one end of the swinging arm is connected to the center frame seat through a rotating shaft, the other end of the swinging arm is vertically downward connected with the pushing arm into a whole, and the sliding sleeve of the lower support adjusting mechanism pushes the pushing arm forwards to enable the lower support connected with the other end of the pushing arm to tilt upwards by taking the rotating shaft of the swinging arm as the center.
The scheme is further as follows: the lower support comprises a tray and a supporting column, the supporting column is perpendicular to the axis of the push arm and fixed at the other end of the push arm, and the tray is connected to the top end of the supporting column through a universal shaft ball.
The utility model has the advantages that: the horizontal support and the vertical support are driven by the stepping adjusting mechanism respectively, so that the automatic adjustment of the center frame is realized, the structure is simple, the operation is convenient, the adjusting precision is high, and the processing precision is improved.
The present invention will be described in detail with reference to the accompanying drawings and examples.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
An automatic adjusting center frame of a grinding machine is shown in figure 1 and comprises a center frame base 1, a dovetail groove 101 connected with a guide rail of the grinding machine is arranged on the bottom end face of the center frame base, a lower support 3 and a horizontal side support 4 corresponding to a processed shaft 2 are arranged on the center frame base, wherein the lower support and the horizontal side support are driven and adjusted through a lower support adjusting mechanism 5 and a horizontal side support adjusting mechanism 6 respectively, the lower support adjusting mechanism and the horizontal side support adjusting mechanism are horizontally arranged up and down, the lower support adjusting mechanism and the horizontal side support adjusting mechanism are two adjusting structures with the same structure, the adjusting mechanism comprises a servo motor 7, and the servo motor 7 is connected with an encoder for controlling the rotating angle of the servo motor so as to control the support propelling distance; servo motor connects a reduction gear 8, and 8 axles of reduction gear have screw 10 through a shaft coupling 9 connection, and the screw cover has screw 11, and the screw is fixed in the centre bore of a sliding sleeve 12, and the sliding sleeve of two regulation structures sets up respectively in two slide holes that set up from top to bottom at the centre frame seat, the sliding sleeve 12 of under bracing adjustment mechanism is connected through a steering linkage 13 to under bracing 3, horizontal side supports 4 and is directly connected with horizontal side support adjustment mechanism's sliding sleeve.
Wherein: the steering link 13 can be regarded as being composed of two parts, wherein the two parts comprise a push arm 1301 and a swing arm 1302, one end of the push arm is connected with a sliding sleeve of the lower support adjusting mechanism and is propped against the top end of the sliding sleeve in the figure, the other end of the push arm is connected with the lower support 3, one end of the swing arm is connected with the center frame seat through a rotating shaft 14, and the other end of the swing arm is vertically downwards connected with the push arm to form a whole body which is 13 shown in the figure; the working principle is as follows: the sliding sleeve of the lower support adjusting mechanism pushes the push arm forwards, so that the lower support connected with the other end of the push arm upwards tilts by taking the rotating shaft of the swing arm as the center to realize the adjustment of the processed shaft 2.
In order to make the lower support 3 have a good contact with the shaft 2 to be machined, in the embodiment: the lower support comprises a tray 301 and a supporting column 302, the supporting column is perpendicular to the axis of the push arm and fixed at the other end of the push arm, and the tray is connected to the top end of the supporting column through a universal shaft ball.
