Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of machining, and particularly relates to a spare set for processing large-bore cylinder barrels of a T2110A type boring machine. BACKGROUND

[0002] A boring machine is a machine tool mainly used for boring existing holes in workpieces with a boring tool. The main feature is that the workpiece does not move during the machining process, while the tool moves, the center of the tool is aligned with the center of the hole, and the tool rotates to perform cutting operations. The currently widely used T2120 and T2110A deep hole drilling and boring machines have a horizontal layout and are mainly used for machining deep holes with a hole diameter ratio (D / L) of 1:6 or more. They have strong rigidity, good precision, a wide range of spindle speeds, and an AC servo motor driven feeding system, which can meet the needs of various deep hole machining processes.

[0003] In practical applications, the T2110A deep hole drilling and boring machine uses a workpiece that does not rotate, a tool that rotates, and a reciprocating feeding motion to drill complex workpieces, small-diameter holes, and bores. When machining large-diameter cylinder barrels, the corresponding spindle needs to be replaced, and the replacement time is as long as half a day to a day. This process not only increases the maintenance time of the equipment and the labor cost, but also significantly reduces the actual production time of the equipment, resulting in a significant reduction in production efficiency, which is not conducive to the competition of enterprises in the market. SUMMARY

[0004] In view of the deficiencies of the prior art, the purpose of the utility model is to provide a spare set for processing large-bore cylinder barrels of a T2110A type boring machine, which can process large-bore cylinder barrels without replacing the spindle by simply replacing the spare parts.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a spare set for processing large-bore cylinder barrels of a T2110A type boring machine, comprising left and right top plates, an adapter, a guide sleeve, and an adjustable rack seat; the left and right top plates are fixed on the boring machine respectively, and the large-bore cylinder barrel is clamped between the left and right top plates; one end of the adapter is connected with the main shaft of the boring machine, and the other end of the adapter is installed with a boring head; the guide sleeve is installed outside the main shaft of the boring machine and is screwed with the right top plate; the large-bore cylinder barrel is assisted and supported by the adjustable rack seat on one side of the middle part.

[0006] As a preferred scheme, the left and right top plates are fixed on the boring machine by screws respectively.

[0007] Further, the left and right top plates are respectively provided with an inner hole chamfer, and the inner hole chamfer is matched with the chamfers at the left and right ends of the large-bore cylinder barrel.

[0008] Further, the boring head is connected with the other end of the adapter through a rectangular thread.

[0009] Further, the adapter is connected to the boring machine spindle through rectangular thread.

[0010] Further, the large-bore cylinder is a φ140 large-bore cylinder, and the boring head is a D140 boring head.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] (1) greatly improve production efficiency: when processing large-bore cylinders by the traditional boring machine, it takes half a day to one day to replace the spindle, which seriously compresses the actual processing and production time of the equipment. By replacing the accessory set instead of the spindle, the boring machine can process other specifications of inner holes. For example, when processing a φ140 large-bore cylinder, the T2110A boring machine only needs to replace the accessory simply, which greatly shortens the preparation time, so that the equipment can be put into production faster, and the production efficiency is improved.

[0013] (2) effectively reduce costs: on the one hand, the human labor input required for frequent replacement of the spindle is reduced. The replacement process of the spindle is complex and needs to be operated by professional technicians, which consumes a lot of labor cost. Now, only ordinary operators are needed to replace the accessory set, so the labor cost is greatly reduced. On the other hand, the equipment maintenance cost is reduced. Frequent replacement of the spindle may cause additional wear and tear of the equipment, increasing repair and maintenance costs. This technical solution avoids this situation, prolongs the service life of the equipment, and reduces the long-term maintenance cost.

[0014] (3) enhance the applicability and flexibility of the equipment: this technical solution enables the boring machine to process multiple specifications of inner holes without replacing the spindle, so that one boring machine can meet the processing needs of different large-bore cylinders, and there is no need to equip multiple boring machines with different spindles for processing different specifications of workpieces, which improves the versatility and utilization rate of the equipment, and enables enterprises to arrange production tasks more flexibly and quickly respond to the diversified needs of the market.
