Detailed Description
Referring to fig. 1-5, the square turning machine of the invention is used for turning a square shaft on a circular shaft 8 and comprises a turning tool 7, a tool rest and a circular shaft bracket 6, wherein the tool rest comprises a cutter disc 3, the cutter disc 3 can perform rotary motion along the center of the cutter disc 3, the turning tool 7 is fixed on the outer circumference of the cutter disc 3, the edge part of the turning tool 7 extends out of the outer circumference of the cutter disc 3, and the cutter disc 3 can drive the turning tool 7 to perform rotary rotation; the circular shaft frame 6 is used for supporting and fixing the circular shaft 8 and can drive the circular shaft 8 to do rotary motion along the axis of the circular shaft 8.
Referring to fig. 1, the outer circumferential surface of the cutterhead 3 and the outer circumferential surface of the circular shaft 8 are attached to each other, and the same rotation linear velocity can be maintained; meanwhile, the radius of the cutter head 3 is an integer multiple of the radius of the circular shaft 8. When the cutter head 3 and the circular shaft 8 are mutually attached, the circular shaft 8 can be cut through the edge part of the turning tool 7 extending out of the cutter head 3, in order to ensure that the turning tool 7 can cut the part next time, the turning is realized through the fact that the radius of the cutter head 3 is an integral multiple of the radius of the circular shaft 8, if the radius of the cutter head 3 is the same as the radius of the circular shaft 8, the cutter head 3 rotates one round, and the turning tool 7 cuts the same position after rotating one round, so that the turning of one side of the circular shaft 8 is realized. Then the round shaft 8 is rotated to change a certain angle, and turning is continued, and the like, so that turning of a plurality of surfaces can be completed, and finally turning of a square shaft or a polygonal shaft is completed.
The outer circumferential surface of the cutterhead 3 and the outer circumferential surface of the circular shaft 8 are mutually fitted, allowing a clearance within a certain tolerance range. Since the turning tool 7 is a plane on which turning is completed in a turning motion, each side of the so-called square or polygonal shaft is not a plane in a strict sense, as shown in fig. 5. The polygonal shaft can also achieve the purpose of convenient transmission, and the connection mode which is dependent on key connection when the circular shaft 8 is used can be omitted.
When the radius of the cutter disc 3 is 2 times of the radius of the circular shaft 8, and the same linear speed is guaranteed, the circular shaft 8 can rotate for two weeks when the cutter disc 3 rotates for one circle, two turning tools 7 can be arranged on the cutter disc 3 and respectively fixed on the outer circumference part of the cutter disc 3, which is 180 degrees away from the central angle, so that the same part of the circular shaft 8 can be turned twice under the condition that the cutter disc 3 rotates for one circle, and the machining precision and the machining efficiency can be effectively improved.
Based on the same principle, a plurality of turning tools 7 are arranged on the outer circumference of the cutter disc 3 at equal intervals, and the turning position of each turning tool 7 can be controlled by controlling the radius of the cutter disc 3, so that turning of polygonal shafts exceeding four sides can be realized.
Referring to fig. 3, in this embodiment, a plurality of turning tools 7 as shown in the figure are provided, when in use, two turning tools 7 with an included angle of 180 degrees can be installed, and the other two turning tools 7 can be not installed; or three turning tools 7 with an included angle of 120 degrees are arranged, and the other turning tool 7 is not arranged. By means of the above-described mounting of the two turning tools 7, the turning operations of the different shapes described above can be completed.
The tool rest further comprises a bed body, a linear moving mechanism is arranged on the bed body, a rotary mechanism is arranged on the linear moving mechanism, a cutter disc 3 is arranged on the rotary mechanism, the rotary mechanism can drive the cutter disc 3 to do rotary motion, and the linear moving mechanism can drive the rotary mechanism to do linear movement along the axis direction of the circular shaft 8. The whole revolving mechanism and the cutterhead 3 arranged on the revolving mechanism can be controlled to linearly move along the axial direction of the circular shaft 8 by the linear moving mechanism, so that a wider turning surface can be turned. In this embodiment, the linear movement mechanism includes a first motor 1 and a screw nut pair 2, the rotation mechanism is disposed on the screw nut pair 2, and the first motor 1 is connected to the screw nut pair 2 in a driving manner. After the first motor 1 rotates and outputs, the screw-nut pair 2 is driven to move, and the linear movement of the slewing mechanism is finally realized, however, the linear movement can be realized by other linear movement mechanisms, such as a straight rack and the like.
The rotary motion mechanism comprises a second motor 5 and a belt transmission mechanism 4, one end of the belt transmission mechanism 4 is in driving connection with the second motor 5, and the other end of the belt transmission mechanism is in driving connection with the cutterhead 3. The second motor 5 drives the belt transmission mechanism 4 to rotate, and the belt transmission mechanism 4 can drive the rotary shaft of the cutterhead 3 to rotate, so that the rotation of the cutterhead 3 is finally realized. Of course, other transmission mechanisms may be used for the belt transmission mechanism 4, such as a gear reduction box, etc.
The clamping of the round shaft 8 can be realized by adopting a common clamping mechanism on a conventional three-jaw chuck, a center and other lathes, one end of the three-jaw chuck is connected with a power mechanism, and the three-jaw chuck can be driven to rotate, so that the round shaft 8 is driven to rotate. As shown in fig. 2, only the chuck portion is schematically shown, and the tip portion is omitted to some extent.
In this embodiment, the circular shaft 8 may be a component having a circular shaft body such as a crankshaft, or may be another component having a circular shaft body, and the principle is the same.
