Abstract

Disclosed is a device for indexing and boring machining of a large disk-type workpiece on a boring mill. The device comprises a corner plate, stepped shafts, radial ball bearings, thrust clamp springs, pressing plates, gaskets, bolts, supporting pins and a locating pin. The two stepped shafts and the two radial ball bearings are fixed in corresponding inner holes in the corner plate through the two thrust clamp springs, and the corner plate is aligned and fixed on a worktable of the boring mill; and the workpiece is placed on the outer circles of the two radial ball bearings and pressed tightly through the four pressing plates, the four gaskets, the four bolts and the four supporting pins. The device for the indexing and boring machining of the large disk-type workpiece on the boring mill is short in manufacturing cycle, low in cost, simple in structure, convenient to machine and wide in usage range; workpieces needing to be machined by a large boring mill can be machined on a small or medium-sized boring mill; and the device overcomes the shortcoming that waste is easily produced when the workpieces are machined on the large boring mill.

Description

On boring machine, the large disc type workpiece is carried out the device of calibration and boring processing

Technical field

The utility model belongs to the machine tools field, relates to a kind of machining calibration and borer, relates in particular to a kind of device that the large disc type workpiece is carried out calibration and boring processing on boring machine.

Background technology

At present, in wind-powered electricity generation, petrochemical industry, often need process uniform five equilibrium connecting hole above two meters disc type work end face at diameter.These connecting hole diameters are big (more than 100 millimeters), and positional precision is higher, can only process on boring machine.Because these disc type work overall dimensions are bigger, are difficult for moving, normally on large-scale borer, a clamping calculates each hole coordinate, and travelling table and main spindle box machine.Large-scale borer costs an arm and a leg, and is very high to workman's technical quality and equipment precision requirement during operation, causes workpiece processing cost height.Owing to add man-hour, easily go out waste product according to each hole coordinate values travelling table and main spindle box.Therefore, develop a kind of simple in structure, can guarantee that product quality, the device that can be on boring machine the workpiece that surpasses the lathe impulse stroke be carried out calibration and boring processing are necessity fully.

The utility model content

The purpose of this utility model is to provide a kind of simple in structure, low cost of manufacture, easily guarantees the device that the large disc type workpiece is carried out calibration and boring processing on boring machine of product quality.

The technical solution of the utility model is: the large disc type workpiece is carried out the device of calibration and boring processing on boring machine, comprising: gusset, step axle, radial ball bearing, thrust jump ring, pressing plate, pad, bolt, a nail, alignment pin; With two thrust jump rings two step axles, two radial ball bearings are fixed in the hole corresponding on the gusset, with the gusset centering and be fixed on the boring table; Workpiece is placed on two radial ball bearing cylindricals, with four pressing plates, four pads, four bolts, four nails with Work-sheet pressing.

The utility model can reach following good effect after adopting technique scheme: this device manufacturing cycle is short, with low cost, simple in structure, easy to process, the scope of application is wide, on medium and small boring machine, just can process the workpiece that needs large-scale borer processing, and solve and add the defective that easily go out waste product man-hour on the large-scale borer.

Description of drawings

Fig. 1 carries out the structural representation of the device of calibration and boring processing to the large disc type workpiece on boring machine for the utility model;

Fig. 2 is the left TV structure schematic diagram of Fig. 1.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.As shown in Figure 1, on boring machine, the large disc type workpiece is carried out the device of calibration and boring processing, comprising: gusset 1, step axle 2, radial ball bearing 3, thrust jump ring 4, pressing plate 6, pad 7, bolt 8, a nail 9, alignment pin 10; According to the drawing requirement of workpiece 5, on gusset 1, process tool bore step axle locating hole, locating hole alignment pin, one tool bore, four nail 9 recesses.The recess degree of depth is greater than the pitch of 8 five times on bolt.Two step axles 2, two two thrust jump rings 4 of radial ball bearing 3 usefulness are fixed in the hole corresponding on the gusset 1, will be fixed on the boring table behind gusset 1 centering.The size of gusset 1 both can be saved material less than workpiece 5 overall dimensions, the loading and unloading of suspender when also being convenient to lift workpiece.Workpiece 5 is placed on two radial ball bearing 3 cylindricals, and is tangent by deadweight and two radial ball bearing 3 cylindricals of workpiece 5, and centering precision is preferably arranged.With four pressing plates 6, four pads 7, four bolts 8, four nails 9 workpiece 5 is compressed.Four nails 9 are placed in the pre-processed recess of gusset 1.During first hole of boring, dress before the workpiece 5 first centering gusset 1 pre-processed to tool bore, this hole is to tool bore, also is the withdrawing hole, the aperture is greater than the aperture that will process on the workpiece 5.Four bolts 8 are unscrewed, and four nails 9 are still in the pre-processed recess of gusset 1, and the screw thread of nail 9 front end is screwed on the pressing plate 6 in the screw, and the adjustable support length dimension guarantees that the workpiece of different-thickness can both compress.Four pressing plates 6 when four bolts 8 are unscrewed, do not have big displacement because of the location of bolt 8, a nail 9, still can block workpiece 5 end faces, prevent that workpiece 5 from toppling over, and guarantee the production safety in the process.Workpiece 5 turns to the pre-processed locating hole place of gusset 1, and alignment pin 10 is inserted in the pre-processed locating hole of gusset 1, the hole that workpiece 5 has been processed.Four bolts 8 are tightened, again boring second hole, completion of processing successively.Because of alignment pin 10 diameter dimensions are bigger, for alleviating the weight of alignment pin 10, alignment pin 10 is made hollow sleeve, alleviate labor strength.
