In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a case grinder, includes rotation portion and grinding portion, the lathe with rotation portion can dismantle the connection, rotation portion with grinding portion adopts the universal joint to be connected, grinding portion and case surface laminating.
Preferably, the rotating part comprises a central shaft, one end of the central shaft is provided with a ball milling support, and the ball milling support is provided with a driving shaft.
Preferably, the ball milling support is connected with the driving shaft by adopting a nut.
Preferably, the grinding part comprises a driven shaft and a lower grinding disc, and the driven shaft is connected with the lower grinding disc by adopting a fastening screw.
Preferably, the driving shaft and the driven shaft are connected by adopting a ball cage type universal joint.
Preferably, the included angle alpha between the driven shaft and the central shaft is 10-15 degrees.
The beneficial effects of this application are:
1. the device drives the rotation part through the lathe and rotates, the rotation part with grinding part adopts the universal joint to be connected, grinding part and case surface laminating, grinding part can be with the different positions contact of case at the rotation in-process to realize the grinding to the case, this device simple structure, convenient operation has solved and has adopted manual grinding case inefficiency, and the processing cost of case grinding is high and the experience of control operating personnel is big problem to the surface grinding influence of case.
2. The lathe is the drilling machine, and drilling machine rotation work drives ball-milling support, ball-milling support with driving shaft bolted connection, grinding portion include driven shaft and lower mill, the driven shaft with lower mill adopts bolted connection, the driving shaft with the driven shaft adopts ball cage type universal joint to connect, and ball-milling support passes through the laminating degree of mill to ball part under the universal joint adjustment, and when the drilling machine was rotatory, lower mill also rotated around this center pin, smears grinding paste and lubricating oil on the ball work piece, makes the ball work piece reach ideal circularity through the rotation of lower mill.
