Description
Technical Field
The utility model relates to an automobile parts technical field, in particular to clamping device is cut to cylinder liner inner face.
Background
The cylinder sleeve is simply called cylinder sleeve, which is embedded in the cylinder barrel of the cylinder body and forms a combustion chamber together with the piston and the cylinder cover. The cylinder liner manufacturing process needs to be from a rough blank to a finished product through fine machining, wherein turning of the inner face of the rough blank is a first process, the cylinder liner of the rough blank needs to be clamped in the cutting process, but only one three-jaw chuck is arranged on a cutting machine tool, the three-jaw chuck cannot clamp the cylinder liner, and therefore a special clamping tool is needed.
Disclosure of Invention
The utility model discloses a remedy prior art's defect provides a can press from both sides tight rough blank's cylinder liner inner face cutting clamping device.
The utility model discloses a realize through following technical scheme:
the device for cutting and clamping the inner surface of the cylinder sleeve comprises a three-jaw chuck, wherein the three-jaw chuck comprises a chuck body and three jaws and is characterized in that clamping steel columns are fixedly arranged on the jaws, the diameters of the three clamping steel columns are equal, the distance from the circle center of each clamping steel column to the circle center of the chuck body is equal, and the diameter of each clamping steel column is 3-6 cm. The diameter of the clamping steel column is 3-6 cm.
And reinforcing ribs are arranged between the clamping steel columns and the clamping claws.
And a positioning device is arranged at the center of the chuck body.
The positioning device is a pit.
The concave pit is in a horn mouth shape.
The positioning device is as follows: a section of round pipe which can be sleeved in the cylinder sleeve is welded at the center of the chuck body.
The round tube is connected with the bell mouth tube at one end, and the round tube and the bell mouth tube are in smooth transition.
The diameter of the clamping steel column is 5 cm.
The utility model has the advantages that:
the clamping steel column is additionally arranged on the three-jaw chuck, which is equivalent to prolonging the clamping area of the clamping jaw; simultaneously, positioner's setting can help the cylinder liner of quick location rough blank, avoids pressing from both sides askewly, influences efficiency.
Drawings
The invention will be further described with reference to the accompanying drawings:
fig. 1 is a schematic front view of a first embodiment of the present invention;
FIG. 2 is a schematic diagram of the right side view of the structure of FIG. 1;
fig. 3 is a right-side structural schematic view of a second embodiment of the present invention;
fig. 4 is a front view of a positioning device in a second embodiment.
In the figure, 1 chuck body, 2 claws, 3 clamping steel columns, 4 reinforcing ribs, 5 pits, 6 round pipes and 7 bell mouth pipes.
Detailed Description
The attached drawings are specific embodiments of the invention. As shown in fig. 1 to 4, the cutting and clamping device for the inner surface of the cylinder sleeve comprises a three-jaw chuck, wherein the three-jaw chuck is provided by a machine tool and comprises a chuck body 1, a bevel pinion and three jaws 2, and the three jaws 2 can simultaneously move along the diameter of the chuck body 1 under the driving of the bevel pinion, so that an object at the position of a circle center is clamped.
In order to clamp the cylinder sleeve, the three clamping steel columns 3 are respectively welded on the three clamping jaws 2, the axial leads of the three clamping steel columns 3 are perpendicular to the moving direction of the clamping jaws 2, the diameters of the three clamping steel columns 3 are equal and are all between 3 and 6 centimeters, preferably 5 centimeters, and the distances from the centers of the three clamping steel columns 3 to the center of the chuck body 1 are equal.
Each clamping steel column 3 and the clamping jaw 2 are reinforced by welding a reinforcing rib 4.
A positioning device is arranged at the central position of the chuck body 1 and used for quickly placing the cylinder sleeve of the rough blank to the central position, so that the rough blank is quickly clamped.
The positioning device has the following two embodiments:
firstly, a pit 5 is directly inwards arranged at the central position of the chuck body 1, the pit 5 is circular, preferably in a bell mouth shape, and the bottom of the pit can just accommodate the outer diameter of the cylinder sleeve.
Secondly, the following steps: a small section of circular tube 6 is welded on the chuck body 1, the section of circular tube 6 can just sleeve the outer diameter of the lower cylinder sleeve, the outer end of the circular tube 6 is integrally connected with a section of bell mouth tube 7, and the circular tube 6 and the bell mouth tube 7 are in smooth transition.
The using process is as follows: and (3) loosening the three clamping claws 2, sleeving one end of the cylinder sleeve of the rough blank in the concave pit 5 or penetrating through the bell mouth pipe 7 to insert the circular pipe 6, then screwing the small bevel gear, and moving the three clamping claws 2 inwards so as to drive the clamping steel column 3 to clamp the cylinder sleeve of the rough blank inwards and perform cutting.
After a long time, the clamping steel columns 3 are abraded in different degrees, the clamping effect is affected, and the surfaces, close to the circle center, of the three clamping steel columns 3 can be cut into arcs with the same size, so that the clamping steel columns can be continuously used.
Other technical features than those described in the specification are known to those skilled in the art.
