Description
Technical Field
The utility model relates to a machine tooling field, especially a cylinder cap hole lapping processingequipment.
Background
The cylinder cover is one of important parts of the engine, the size and roughness precision of an assembling inner hole of the cylinder cover are particularly important, and the position precision of the engine and other parts is directly influenced after the cylinder cover is assembled, so that the operation of the whole engine is influenced. Because the size range of the cylinder cover is large, the traditional machining tool and the traditional machining method are difficult to ensure good machining precision when being used for machining. Therefore, at present, many enterprises can choose novel equipment with higher cost for processing, and thus the problem of cost is brought. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
Disclosure of Invention
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed, repeated positioning accuracy is high to can be under lathe low-speed state accurate control size and roughness tolerance, raise the efficiency and precision, guarantee product processingquality's cylinder cap hole lapping processingequipment.
The technical solution of the utility model is that: the utility model provides a cylinder cap hole lapping processingequipment, includes positioning seat 1, its characterized in that: the end part of the positioning seat 1 is provided with a supporting frame 2 with a cross-shaped section, four sets of fine grinding mechanisms are uniformly distributed on the supporting frame 2,
the lapping mechanism comprises a fixed frame 3 which is connected in the supporting frame 2 in a sliding way, one end of the fixed frame 3, which faces the outer side of the supporting frame 2, is provided with an oilstone strip 4, the other end is provided with a mandril 5, the lapping mechanism also comprises a spring 6 which is arranged in the inner cavity of the supporting frame 2, one end of the spring 6 is fixed on the inner wall of the supporting frame 2, the other end is fixed on the mandril 5, the supporting frame 2 is connected with a positioning pin 7 in a penetrating way, the middle part of the fixed frame 3 is provided with a long groove 8, the positioning pin 7 is positioned in the long,
and chamfers are arranged at two ends of the oilstone strip 4.
Compared with the prior art, the utility model, have following advantage:
this kind of structural style's piston pin hole processing positioner, its simple structure, design benefit, rationally distributed. The cylinder cover inner hole fine grinding device is designed aiming at the problems of the traditional grinding equipment and the traditional grinding mode in the using process, is high in repeated positioning precision, can accurately control the size and the surface roughness tolerance under the low-speed state of a machine tool, improves the efficiency and the precision, and ensures the product processing quality. The device has the advantages of simple manufacturing process and low manufacturing cost, so the device has various advantages, is particularly suitable for popularization and application in the field, and has very wide market prospect.
Drawings
Fig. 1 is a front view of an embodiment of the present invention.
Fig. 2 is a side view of an embodiment of the invention.
Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 and 2: a cylinder cover inner hole lapping processing device comprises a positioning seat 1 as a base, a supporting frame 2 with a cross-shaped section is arranged at the end part of the positioning seat 1, four sets of lapping mechanisms are uniformly distributed on the supporting frame 2,
the lapping mechanism comprises a fixing frame 3 which is connected inside a support frame 2 in a sliding mode, one end, facing the outer side of the support frame 2, of the fixing frame 3 is provided with an oilstone strip 4, the other end of the fixing frame is provided with an ejector rod 5, the lapping mechanism further comprises a spring 6 arranged in an inner cavity of the support frame 2, one end of the spring 6 is fixed on the inner wall of the support frame 2, the other end of the spring 6 is fixed on the ejector rod 5, a positioning pin 7 penetrates through the support frame 2, the middle of the fixing frame 3 is provided with an elongated slot 8, the positioning pin 7 is located in the elongated slot 8, and two ends of the oilstone strip.
The utility model discloses cylinder cap hole lapping processingequipment's working process as follows: firstly fix the positioning seat 1 to the tool post of lathe and carry out the locking location, the lathe starts the back, the knife rest moves forward, because the tip of oilstone strip 4 is provided with the chamfer, under the effect of this chamfer, oilstone strip 4 can be pushed down by the pore wall (spring 6 compresses tightly), thereby let whole support frame 2 enter into among the hole of work piece, because the existence of spring 6, all oilstone strips 4 all can apply forward pressure to the inner wall of hole, the work piece is rotatory for positioning seat 1, and this device does the removal from beginning to end for the work piece, and then utilize oilstone strip 4 to carry out the lapping to the internal hole surface, carry out the detection of roughness after the repeated grinding, until roughness reaches the standard that accords with the drawing requirement.
