Abstract

The utility model discloses a driving mechanism of an edge milling machine. A driving box body is mounted on a side surface of a machine body through a linear guide rail, a two-speed reduction gearbox is mounted on the driving box body through a mounting plate, an input end of the two-speed reduction gearbox is connected with a driving motor, a toothed wheel is arranged on an output shaft of the two-speed reduction gearbox, the toothed wheel is meshed with a toothed rack on the side surface of the machine body, and a limiting switch is mounted at a corner of the driving box body. According to the driving mechanism of the edge milling machine, the linear guide rail is used as a bearing guide structure, and therefore driving force is lowered, vibration of a workpiece in the process of milling is reduced, and machining precision is significantly improved. Since the two-speed reduction gearbox which is provided with a variable frequency motor and a three-phase asynchronous motor is provided, and the transmission method that the output toothed wheel is meshed with the toothed rack is used, a feeding speed is utilized when the workpiece is in the milling process, and the return stroke utilizes a high backward speed when the milling process is finished. Therefore, high-efficiency milling process including the feeding speed and the high backward speed is achieved, time is saved, and production efficiency is greatly improved.

Description

The edge milling machines driving mechanism

Technical field

The utility model relates to metal milling device field, specifically drives the mechanism of milling unit head in the edge milling machines equipment.

Background technology

In prior art, the driving mechanism that edge milling machines equipment uses adopts the type of belt drive of variable-frequency motor, reduction box and the engagement of output gear wheel and rack usually, and it has set single milling work speed, can not carry out quick return; Relatively lose time inefficiency in the course of the work.The supporting guide frame of driving mechanism generally all adopts rectangular guideway to add the application specific architecture of adjusting gag, and the equipment making cycle is long, and processing technology is complicated, and machining accuracy is difficult for guaranteeing.

The utility model content

The purpose of the utility model is to overcome the above-mentioned deficiency that exists in the prior art, a kind of simple in structure, rational edge milling machines driving mechanism of accurate positioning is provided, thereby has improved machining accuracy and production efficiency greatly.

The technical scheme of the utility model is:

A kind of edge milling machines driving mechanism; Drive case is installed in lathe bed assembly side through line slideway; The dual-ratio reduction case is installed on the drive case through installing plate, and the input of dual-ratio reduction case is connected with drive motors, on the output shaft of dual-ratio reduction case gear is installed; Gear is meshed with the tooth bar of lathe bed assembly side, and limit switch is installed in the bight of drive case.

Further improvement as technique scheme: said edge milling machines driving mechanism is separately positioned on the left and right sides face of lathe bed assembly.

The beneficial effect of the utility model is;

The utility model adopts line slideway as the supporting guide frame, has reduced driving force, has reduced the vibration in the workpiece milling process, has significantly improved machining accuracy.The utility model is through being equipped with the dual-ratio reduction case of a variable-frequency motor and a threephase asynchronous machine; And the type of belt drive of output gear wheel and rack engagement; When the milling workpiece, adopt work speed; Rewind down speed is adopted in the milling backhaul that finishes, and has realized that the worker advances, the processing of rewind down high efficiency milling, saves time and has improved production efficiency greatly.

Among the figure: 1, limit switch; 2, drive motors; 3, dual-ratio reduction case; 4, drive case; 5, retaining bits groove; 6, gear; 7, holding screw; 8, holding screw; 9, installing plate; 10, lathe bed assembly; 11, line slideway; 12, tooth bar.

The specific embodiment

Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.

As 1 to shown in Figure 3; The drive case 4 of the described edge milling machines driving mechanism of the utility model is installed in lathe bed assembly 10 sides through two line slideways 11 up and down; Like Fig. 2, shown in Figure 3, can be respectively arranged with the utility model at the left and right sides of lathe bed assembly 10 face.Dual-ratio reduction case 3 is being installed on the drive case 4 through installing plate 9, and the input of dual-ratio reduction case 3 is connected with drive motors 2, through the key transmission gear 6 is installed on dual-ratio reduction case 3 output shafts; Gear 6 is meshed with the tooth bar 12 of lathe bed assembly 10 sides, thus drive the utility model along line slideway 11 in the slippage of the side of lathe bed assembly 10.Limit switch 1 is installed in the bight of drive case 4.

Holding screw 7 is installed on the gear 6, prevents gear 6 axial float on the output shaft of dual-ratio reduction case 3; Retaining bits groove 5 is installed on the drive case 4, prevents that iron filings from falling into lathe bed protective cover groove; The effect of holding screw 8 be when drive case 4 vibrated and impulsive force after; Line slideway and slide block depart from original fixed position probably; And influence precision, thus can adjust the slide position through adjustment holding screw 8 this moment, guarantee the running precision of drive case.

The utility model utilizes line slideway carry drive case, and operating accuracy is high, and accurate positioning reduces driving force significantly, and the big rigidity of bearing capacity is strong.The utility model is through being equipped with the dual-ratio reduction case of a variable-frequency motor and a threephase asynchronous machine; And the type of belt drive of output gear wheel and rack engagement; When the milling workpiece, adopt work speed; Rewind down speed is adopted in the milling backhaul that finishes, and has realized that the worker advances, the processing of rewind down high efficiency milling, saves time and has improved production efficiency greatly.
