Abstract
The utility model relates to a quick-open and slow-close mechanism for an armless tool magazine. The mechanism comprises a protective door (1) pushed by a cylinder, and is characterized in that the mechanism also comprises a roller shelf (2), a roller (3), a roller guide plate (4) and a bracket (5), wherein a roller trough is formed on the roller guide plate (4), and comprises a straight trough (4-2) and an arc-shaped trough (4-1) which are connected together; the roller (3) is arranged on the roller shelf (2) and positioned in the roller trough; the roller shelf (2) is fixed on the protective door (1); and the roller guide plate (4) is fixed on the bracket (5). The utility model avoids the mutual interference between a machine tool spindle and the protective door, thereby improving the adaptability of the opening and closing mechanism.
Description
Technical field
The utility model relates to a kind of umbrella shape tool magazine and changes down the mechanism of closing the door soon, belongs to the functional part of lathe class vertical machining centre.
Background technology
At present, adopt toggle to realize (as Fig. 1) to the switching of tool magazine protective door both at home and abroad, this mechanism sending and returning with cutterhead, opens and closes protective door synchronously gradually more.Its critical defect is that cutterhead is not sent fully and put in place, and then protective door is not just opened fully.Otherwise cutterhead is return the initial stage, and protective door then starts closes the door, and often causes machine tool chief axis and protective door to interfere with each other.Given this, the scope of application of tool magazine is restricted, for some type (the relative main spindle box flange of main shaft nose installed surface distance be main shaft overhang less or the spindle flange diameter bigger) just inapplicable fully.
Summary of the invention
The purpose of this utility model provides a kind of machine tool chief axis and protective door can avoided and interferes with each other, and adaptable umbrella shape tool magazine changes down the mechanism of closing the door soon.
The technical scheme that realizes above-mentioned purpose is: a kind of umbrella shape tool magazine changes down the mechanism of closing the door soon, comprise the protective door that promotes by cylinder, also comprise turning rolls, roller, roller guide plate and support, have roller groove on the roller guide plate, and roller groove is made up of the straight trough that connects together and deep-slotted chip breaker two parts, roller is assemblied on the turning rolls and is arranged in roller groove, and turning rolls is fixed on the protective door, and the roller guide plate is fixed on the support.
After adopting technique scheme, protective door under the cylinder thrust with in the cutterhead moving linearly, roller is moved along a curved path along the guide plate groove by the constraint of roller guide plate, thereby making protective door send first half term at cylinder does to do gyration around the cutter rotary axle, promptly open protective door, this moment, roller was positioned at the deep-slotted chip breaker of roller groove.Send the second half at cylinder, because of roller is arranged in the straight-line groove of roller groove, do not stress along the cylinder thrust direction, protective door does not then rotate.Otherwise, then opposite when cylinder is return.Thereby the phenomenon of having avoided machine tool chief axis and protective door to interfere with each other has improved the adaptability of switching mechanism.
Description of drawings
Fig. 1 is the structural representation of protective door switching mechanism in the prior art;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 sends the structural representation of first half term at cylinder for the utility model;
Fig. 4 sends the structural representation of the second half at cylinder for the utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 2, a kind of umbrella shape tool magazine changes down the mechanism of closing the door soon, comprise the protective door 1 that promotes by cylinder, also comprise turning rolls 2, roller 3, roller guide plate 4 and support 5, have roller groove on the roller guide plate 4, and roller groove is made up of the straight trough 4-2 that connects together and deep-slotted chip breaker 4-1 two parts, roller 3 is assemblied on the turning rolls 2 and is arranged in roller groove, turning rolls 2 is fixed on the protective door 1, and roller guide plate 4 is fixed on the support 5.
Shown in Fig. 3,4, operation principle of the present utility model is as follows:
Claims (1)
1, a kind of umbrella shape tool magazine changes down the mechanism of closing the door soon, comprise the protective door (1) that promotes by cylinder, it is characterized in that: also comprise turning rolls (2), roller (3), roller guide plate (4) and support (5), the roller guide plate has roller groove on (4), and roller groove is made up of the straight trough that connects together (4-2) and deep-slotted chip breaker (4-1) two parts, roller (3) is assemblied on the turning rolls (2) and is arranged in roller groove, turning rolls (2) is fixed on the protective door (1), and roller guide plate (4) is fixed on the support (5).
