Abstract

The utility model discloses a swinging arm straight-line tool magazine, which aims at providing the swinging arm straight-line tool magazine with flexible and reliable motion, small occupation area, and compact structure. The swinging arm straight-line tool magazine comprises a supporting seat, a cylinder, two pairs of connecting rods that are parallel to each other, a cutter frame, an upper protecting hood, a lower protecting hood, etc., wherein, the cutter frame is connected with a machine tool through the two pairs of connecting rods, so as to ensure that a cutter always keeps the vertical position during the tool magazine is pushed out. Under the push of the cylinder, the cutter frame rotates around the fixed end of the connecting rods, at the same time, and the protecting hoods of the tool magazine are opened by a connecting rod mechanism. In order to ensure the service life of the cylinder, a swing link carrier of the cylinder is designed into a universal radial type, so as to avoid the cylinder from bearing the radial force during the operation because of the mechanical error. The swinging arm straight-line tool magazine only occupies the stroke in one axial direction of the machine tool, pulls out of the processing zone when the machine tool works and pushes out of the processing zone when the machine tool changes the cutter, so not only the tool change function is realized, but also a larger processing zone can be ensured. The swinging arm straight-line tool magazine is suitable for a middle-small numerical control milling machine.

Description

The in line tool magazine of a kind of swing arm

Technical field:

The utility model relates to a kind of tool magazine, particularly relates to a kind of in line tool magazine of swing arm that is applicable to middle-size and small-size vertical numerical control milling machine.

Background technology:

The vertical numerical control milling machine is one of widely used Metal Cutting Machine Tool in the machining, on this lathe tool magazine is installed, and utilizes the relative engagement action of main shaft and tool magazine, reaches main shaft and takes off the purpose that cutter carries out machining from the tool magazine place.Existing tool magazine, as: umbrella shape, disc type, umbrella formula etc., volume is all bigger, and price is also all than higher, and is compact for the space, and middle-size and small-size Digit Control Machine Tool on the low side is not suitable for very much.

Summary of the invention:

Technical problem to be solved in the utility model is the shortcoming that overcomes prior art, provides that a kind of flexible movements are reliable, floor space is little, the in line tool magazine of the swing arm of compact conformation.

The technical solution of the utility model is summarized as follows:

The in line tool magazine of a kind of swing arm is characterized in that being made up of bearing 1, cylinder 2, connecting rod 5 and 8, knife rest 7, guard shield (dividing two parts 6 and 10 up and down) etc.Knife rest is connected with lathe by two pairs of parallel rods, guarantees that cutter remains vertical position in the tool magazine push.Under the promotion of cylinder, knife rest is around the stiff end rotation of connecting rod, and the tool magazine guard shield is also opened by linkage simultaneously.In order to guarantee the service life of cylinder, the gantry pillars of cylinder is designed to the universal hinging formula, avoids because the error of machinery makes cylinder be subjected to radial load in running.

The in line tool magazine of this swing arm only takies axial stroke of lathe, during lathe work tool magazine is pulled out machining area, releases during tool changing, has both realized the tool changing function, has guaranteed bigger machining area again.

Description of drawings:

Fig. 1 is that space mechanism of the present utility model launches schematic diagram;

Fig. 2 is the schematic diagram that the utility model tool magazine retracts state;

Fig. 3 is the schematic diagram that the utility model tool magazine is released state.

The specific embodiment:

As shown in Figure 1, the in line tool magazine of swing arm comprises bearing 1, cylinder 2, connecting rod 5 and 8, knife rest 7, guard shield parts such as (dividing two parts 10 and 6 up and down).Wherein, bearing 1 is used for connecting tool magazine and lathe; Cylinder 2 provides power, is used for releasing and retracting knife rest; Connecting rod 5 and 8 rectilinear motions with cylinder piston rod transfer the swing of knife rest to; Knife rest 7 is used for placing cutter; Guard shield is two parts (being respectively 10 and 6) up and down, is used to protect tool magazine not to be subjected to the influence of smear metal etc. when machine tooling.

The in line tool magazine of this swing arm can be divided into four basic systems (as shown in Figure 1), is respectively: the 1) four-bar mechanism of being made up of

member

1,2,3,5 is used for the swing around stiff end of connecting rod that the rectilinear motion of cylinder is converted to.2) double rocker mechanism of forming by

member

1,5,7,8, member 5 and 8 is connecting rods, is the critical component in the whole tool magazine mechanism, they couple together knife rest and lathe.The utility model has adopted two groups of above-mentioned double rocker mechanisms, with this connecting rod 5 and 8 swing is changed into the parallel of knife rest and moves, thereby make cutter remain vertical position.These two groups of double rocker mechanisms are mutually corresponding and parallel, during installation the connecting rod of their correspondences must keep enough with one heart.3) four-bar mechanism of being made up of

member

1,5,4,6 can change into the swing of connecting rod 5 swing of lower shield 6, thereby under the situation that cylinder promotes the lower shield of tool magazine is opened.4) four-bar mechanism of being made up of

member

1,8,9,10 can change into the swing of connecting rod 8 swing of upper shield 10, thereby under the situation that cylinder promotes the upper shield of tool magazine is opened.Like this, by above-mentioned four mechanism's cooperatively interacting in spatial dimension, when cylinder promotes, can guarantee smoothly tool magazine up and down outer cover open, knife rest is released simultaneously, as shown in Figure 2; Reverse when mobile when cylinder, knife rest is regained, and tool magazine outer cover is up and down closed, as shown in Figure 3.

In order to guarantee the service life of cylinder, the gantry pillars of cylinder is designed to the universal hinging formula, avoids because the error of machinery makes cylinder be subjected to radial load in running.
