Abstract
The utility model relates to a cutter head for milling a key sot, which comprises a milling tool bit, a bevel gear and a cylindrical gear; a milling mechanism is provided with a cutter shaft hole, the milling tool bit is installed on the upper part of the cutter shaft hole, and the milling tool bit is of a narrow cylindrical structure with a T-shaped groove; and the bevel gear is engaged with the cylindrical gear below the milling tool bit so as to realize the transmission. The cutter head for milling a key slot has simple and reliable structure and convenient operation, improves the production efficiency, can high-efficiently process the key slots which presents in a 90-DEG angle, and can satisfy the requirements of the product quality and the production efficiency.
Description
Technical field
The utility model relates to a kind of milling head of machining equipment, relates in particular to a kind of milling head of 90 ° of milling key grooves each other of processing.
Background technology
The shape of milling cutter has a variety of, plain-milling machine and CNC milling machine working groove and outline of straight line, mills processing cavity on the boring machining center, core, curved profile/profile and uses.Milling cutter generally has: the tack milling cutter, rough mill, remove a large amount of blanks, small size horizontal plane or profile finish-milling; Rose cutter carries out curved surface half finish-milling and finish-milling; Profile milling cutter comprises rose reamer, T shape milling cutter, flute profile cutter, interior R cutter, T type cutter millable T type groove wherein, and flute profile cutter wherein can mill out various flute profiles.Be illustrated in figure 2 as the godet wheel hub part that to process, its material is No. 35 steel, the parts label is in two holes of 11 keyway of 90 ° each other to be arranged respectively among the figure, its dimensional accuracy is 63.5 ± 0.037,371 (+0.5/+0.3), Tolerance of Degree of position requires symmetry 0.025, if machining according to routine, as slotting, planing, processing modes such as milling, because processing parts is the large disc type structure, and certain production lot is arranged, more existing Metal Cutting Machine Tools also are not suitable for processing, and therefore just can't satisfy the requirement of product quality and production efficiency.
The utility model content
At above defective, the purpose of this utility model provides a kind of simple in structure and reliable, easy to operate, milling head that can satisfy the milling key groove of existing process requirements, thereby can be efficiently the keyway that is mutually 90 ° be carried out process operation.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of milling head of milling key groove comprises milling cutter head, bevel gear and roller gear, and milling mechanism is provided with the cutter shaft hole, and the tapering in described cutter shaft hole is set to 7: 24 ratios; Described milling cutter head is installed in top, cutter shaft hole, and the milling cutter head is the long and narrow cylindrical-shaped structure that has T type groove; The following side bevel gear of described milling cutter head and roller gear are meshing with each other and realize transmission; The end of milling mechanism is connected with machine tool chief axis and transmits moment of torsion drive milling cutter head by the key piece and carry out milling.
The beneficial effect of the milling head of milling key groove described in the utility model is: simple and reliable for structure, easy to operate, improved production efficiency to a certain extent, can be efficiently the keyway that is mutually 90 ° be carried out process operation; Solve the problem that some Metal Cutting Machine Tools are not suitable for carrying out special processing, satisfied product quality and production efficiency double requirements.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the structural representation of the milling head of the described milling key groove of the utility model embodiment;
Fig. 2 is the godet wheel hub part drawing that has 90 ° of groove millings to be processed.
Among the figure:
1, milling cutter head; 2, cutter shaft hole; 3, machine tool chief axis; 4, bevel gear; 5, roller gear; 6, screw mandrel; 7, fixture; 8, support member; 9, bolt; 10, housing.
The specific embodiment
Shown in Fig. 1-2, the milling head of milling key groove described in the utility model comprises milling cutter head 1, bevel gear 4 and roller gear 5, and milling mechanism is provided with cutter shaft hole 2, and the tapering in described cutter shaft hole 2 is set to 7: 24 ratios to make things convenient for the installation of general key groove milling cutter; Described milling cutter head 1 is installed in 2 tops, cutter shaft hole, and milling cutter head 1 can be realized the function of half-twist for having the long and narrow cylindrical-shaped structure of T type groove; The below of described milling cutter head 1 is provided with some bevel gears 4 and roller gear 5, and described bevel gear 4 is meshing with each other with roller gear 5 and realizes transmission; The end of milling mechanism is connected with machine tool chief axis 3 and transmits moment of torsion drive milling cutter head 1 by the key piece and carry out milling, milling mechanism is provided with the screw mandrel 6 that has fixture 7, described screw mandrel 6 is provided with support member 8, and described milling mechanism is connected on the housing 10 by bolt 9.
More than the milling head of milling key groove described in the utility model, can process godet wheel hub part as shown in Figure 2, its material is No. 35 steel, a keyway 11 of 90 ° is each other respectively arranged in two holes, its dimensional accuracy be 63.5 ± 0.037,371 (+0.5/+0.3), Tolerance of Degree of position requires symmetry 0.025, add man-hour, godet wheel hub part to be processed is close to clamping on the angle bar bearing, allow the milling cutter head 1 that has cotter mill cutter put in the hole in piece part, can finish the milling operation, therefore can satisfy the two-way requirement of product quality and production efficiency.
The advantage that more than shows and described principal character of the present utility model and had.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the utility model also has some variations and improves under the prerequisite that does not break away from the utility model purport and scope, and these changes and improvements all fall in claimed the utility model scope.
