Abstract

The utility model discloses a rapid adjustable boring cutter head which is used for the boring process of cylinder bodies and other parts. The cutter disk is composed of a cutter head body (1), a semicircle fine adjustment block connected with the cutter head body (1) through a pin shaft, and a semicircle clamping slide block (3) able to slide along the inner circle groove of the cutter head body (1). During the boring time, as long as the clamping and cutter head positions are adjusted without moving a boring bar, the boring position can be freely adjusted without being affected by the cutter head hole position of the boring bar. The fine adjustment of the cutter head is convenient and reliable, the boring hole scope is big, the measuring is convenient and exact, and the boring precision is high.

Description

Rapid adjustable boring cutterhead

The utility model belongs to a kind of accessory on the used boring machine of machining.

Used boring cutter is directly to be contained in cutter head on the boring bar on the boring machine at present, when adjusting boring cutter, will mobile at any time boring cutter bar position, that cutter head also is subjected to the length of restriction, cutter head of cutter head hole site on the boring bar is certain, it is very difficult when cutter head need be finely tuned, be difficult to the boring precision that reaches required, and efficient is low.

The purpose of this utility model is a kind of adjustable boring tool dish of design, and its clamping on boring bar, when adjusting boring cutter, is only needed mobile boring head, also is provided with the cutter head micromatic setting in addition on boring head, to improve the boring precision.

The utility model is to adopt following technical proposal to realize: the semicircle fine setting piece 2 that 1. is connected by bearing pin by cutter head 1, with cutter head 1, the semicircle of sliding along circle groove in the cutter head 1 tighten slide block 3 and are constituted.

Fig. 1 is the main vertical view of quick change adjustable boring tool dish.

Fig. 2 is the D-D cutaway view of Fig. 1.

Fig. 3 is the A-A cutaway view of Fig. 1.

Fig. 4 is the C-C cutaway view of Fig. 1.

Fig. 5 is the B-B cutaway view of Fig. 1.

1-5 is further described formation of the present utility model and use in conjunction with the accompanying drawings:

The endoporus clamping of cutter head 1 by being milled with the U-shaped groove is on boring bar shown in Fig. 3,4, shown in Figure 4 by tightening slide block 3(simultaneously along the semicircle that circle groove in the cutter head 1 slides) slip obvolvent and 4. that slide block 3 is fastening with sunk screw, thus hold tightly on boring bar with making cutter head 1 and chucking 3 wholecircle week of slide block property.It is interior and 2. that cutter head is fastening with holding screw that cutter head shown in Fig. 1,3 then is contained in the dress tool bore of finely tuning piece 2.Fig. 2, the piece 2 of fine setting shown in 3 is semicircle blocks that 1. are connected by bearing pin with cutter head 1, because 1. it can rotate around bearing pin, so be contained in the collapsing length of the cutter head above it except that can 2. adjusting by holding screw, 3. two pan head screws that also can use fine setting piece 2 to be connected with cutter head 1 radially finely tune fine setting piece 2, thereby finely tuned the size of cutter head, these two screws that play the fine setting effect 3. one work to connect fine setting piece 2 and cutter head 1, shown in Figure 5 another works to finely tuning piece 2 top liftings, so just can make fine setting piece 2 and cutter head obtain fine setting by regulating these two screws.

Advantage of the present utility model: when bore hole is adjusted boring cutter, as long as on boring bar the clamping boring head, just do not need mobile knife bar position, the position that at this moment only needs the levelling boring head just can, the levelling boring head is rapidly convenient. The boring cutter present position is not subjected to the restriction of cutter head hole site on the boring cutter bar, can freely adjust. The cutter head fine setting is convenient, can use the rimmer knife head, also can use short sword head bore hole scope big. The precision height can be controlled in 0.01mm. Can use the flexible height of general vernier caliper measurement boring cutter, it is convenient, accurate to measure. The utility model not only makes things convenient for handy but also cost is low.

Claims

1, a kind of quick change adjustable boring tool dish is characterized in that it is that the semicircle fine setting piece (2) that 1. is connected by bearing pin by cutter head (1), with cutter head (1), the semicircle chucking slide block (3) that slides along circle groove in the cutter head (1) are constituted.

2, by the described quick change adjustable boring tool of claim 1 dish, it is characterized in that trip bolt that centre position in fine setting piece (2) is provided with dress tool bore and tightening cutter head 2., also be provided with at the other end of fine setting piece (2) and be connected with the other end of cutter head (1) and 3. fine setting piece (2) is carried out two pan head screws that warp-wise finely tunes.

3,, it is characterized in that when an end of semicircle chucking slide block (3) is equipped with the slip obvolvent, making its fixing fixture 4. by the described quick change adjustable boring tool of claim 1 dish.
