Abstract
A changing tool arm mechanism which can fast adjust the strength of a synchronous grabbing tool comprises a changing tool arm (10), a tool claw bar (30) and a tool claw bar spring (38), wherein the tool claw bar spring (38) is engaged with the tool claw bar (30) and arranged on the changing tool arm (10). The changing tool arm mechanism is characterized in that fixing rod sleeves (62) are vertically arranged on the changing tool arm (10) in pairs, a fixing rod (50) with an inclined surface (80) and a fixing rod groove (53) is sleeved in each fixing rod sleeve (62), the lower end of each fixing rod (50) is equipped with a fixing rod spring (58), adjusting nuts (66) and adjusting screws (68) which are arranged outside the fixing rod sleeves (62) are connected via fixing rod adjusting blocks (60) arranged at one end of the fixing rod springs (58), and one end of the tool claw bar (30) is contacted with the fixing rod (62), and the other end is pushed on the tool claw bar spring (38). The changing tool arm mechanism has the advantages that the changing tool arm mechanism can adjust the spring tension without changing the tool claw bar spring, and thereby guaranteeing the strength of the grabbing tool.
Description
Technical field:
The utility model relates to a kind of tool change arm structure, the especially a kind of tool change arm structure that can rapid adjustment grab button cutter intensity synchronously.
Background technology:
Nowadays the numerical control machining center that is using generally adopts automatic tool changer to carry out the replacing of process tool, can save a large amount of time like this, and makes whole exchanging knives process safer than in the past; But the problem that exists is: the cutter claw bar spring in the long-time cutter-exchange mechanism that uses can inevitably produce elastic fatigue, therefore in exchanging knives process, the poor effect that occurs the fastening/stage property that gets loose easily, tool changing action is phenomenon smoothly inadequately, sometimes cutter even can fly off causes the damage of machining center equipment and personnel's injures and deaths.
Summary of the invention:
The utility model is in order to solve existing in prior technology the problems referred to above, and providing a kind of can adjust the spring elasticity, and then guarantee the tool change arm structure of button cutter intensity not more under the situation of tool changing claw bar spring.
Technical solution of the present utility model is: but a kind of rapid adjustment is grabbed the tool change arm structure of button cutter intensity synchronously, comprise tool change arm 10, cutter claw bar 30 and the cutter claw bar spring 38 that matches with it are arranged on the tool change arm 10, it is characterized in that: vertically be provided with fixed bar axle sleeve 62 on the tool change arm 10 in pairs, socket is provided with the fixed bar 50 of inclined-plane 80 and fixed bar groove 53 in the fixed bar axle sleeve 62, the lower end of fixed bar 50 is provided with fixed bar spring 58, being arranged on fixed bar axle sleeve 62 outer adjustment nuts 66 is connected by the fixed bar adjustment piece 60 that is arranged on fixed bar spring 58 1 ends with adjustment screw 68, one end of cutter claw bar 30 contacts with fixed bar 62, on the cutter claw bar spring 38 that the other end withstands on.
Described inclined-plane 80 is in vertical direction with α degree angle, angular range: 10-20 degree.
The contact tip of described cutter claw bar 30 is spherical, and it is provided with cutter claw bar catch 57.
The upper end of described fixed bar 50 is provided with steel ball 54.
The utility model is compared with prior art, has following advantage:
1. avoid because long-time the use causes that cutter claw bar spring produces elastic fatigue in the cutter-exchange mechanism, make tool changing move slack phenomenon and take place, guarantee finishing quality and deadline of whole tool changing action;
2. can certain maintenance cost and valuable time have been saved in the rate of tension of more not adjusting spring under the situation of tool changing claw bar spring;
3. (tool weight is bigger, and tool change time increases the rate of tension of spring more in short-term for the rate of tension that can adjust cutter claw bar spring according to the weight and the tool change time of concrete cutter for same; Otherwise tool weight is less, when tool change time is longer relatively then.)；
4. equipment and operating personnel's safety in can the safety action process.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment tool change arm part.
Fig. 2 is the partial enlarged drawing of the utility model embodiment tool change arm part.
Fig. 3 is the overall structure schematic diagram of the utility model embodiment.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.As Fig. 1, Fig. 2, shown in Figure 3: but a kind of rapid adjustment is grabbed the tool change arm structure of button cutter intensity synchronously, comprises tool change arm 10, vertically is provided with fixed bar axle sleeve 62 on tool change arm 10 in pairs, and fixed bar 50 is socketed in the fixed bar axle sleeve 62, and can slide within it; Fixed bar 50 is provided with fixed bar groove 53, and the below of fixed bar groove 53 is provided with inclined-plane 80, and inclined-plane 80 is in vertical direction with the certain angle setting, angular range: 10-20 degree;
Be provided with fixed bar spring 58 in the lower end of fixed bar 50, its lower end is provided with fixed bar and adjusts piece 58, in order to adjust the vertical position of fixed bar; The top that fixed bar is adjusted piece 60 is against the lower end of fixed bar spring 58, the bottom be arranged on fixed bar axle sleeve 62 adjustment nut 66 outward and be connected;
Also be horizontally arranged with on the tool change arm 10 and fixed bar 50 contacted cutter claw bars 30, the contact tip of cutter claw bar 30 is set to sphere, and also is provided with cutter claw bar catch 57 on the termination, and the other end of cutter claw bar 30 is connected with cutter claw bar spring 38;
Be provided with steel ball 54 in the upper end of fixed bar 50.
When cutter claw bar spring longer service time, when producing elastic fatigue, the artificial nut 66 of adjusting, be attached thereto the fixed bar adjustment piece 60 that connects and under it drives, do lengthwise movement, thereby fixed bar 50 is moved in the vertical, and then the contact position of change cutter claw bar 57 and fixed bar 50, because cutter claw bar 57 and the contact-making surface of fixed bar 50 are inclined-plane 80 (angular range of its tilt angle alpha: with become the 10-20 degree on the vertical direction), reach the purpose of adjusting cutter claw bar 57 position in the horizontal, the cutter claw bar spring 38 that be arranged on cutter claw bar 57 other ends this moment changes rate of tension thereupon, and then make-up cutter intensity is adjusted.
On the spherical contact tip of cutter claw bar 30, also be provided with cutter claw bar catch 57, can make the cutter claw bar button that fastens annular groove on the cutter support portion 35 and successfully be retracted in the tool change arm 10, so just can be not stuck in fixing dried groove 53 when getting loose cutter.
When tool changing, the tool changing axle of machining center drives tool change arm 10 and rotates, and the steel ball 54 that is arranged on fixed bar 50 upper ends this moment rolls, and reduces each and is in contact with one another friction between the part, both can make the tool changing action smooth more, can prolong the service life of part again.
