Abstract
The utility model discloses a tool change mechanism used in a mechanical machining center. The tool change mechanism comprises a motor (1) arranged on a bracing frame (2), a camshaft (3) connected with the motor (1), and a tool arm main shaft (5). The tool is characterized in that a retainer ring (4) is fixed at a tip of the camshaft (3); an inductive block (6) is fixed on the retainer ring (4); two close-spaced switches (8) which are matched with the inductive block (6) and connected with an electric control gear are fixed on the bracing frame. When in work, the inductive block (6) rotates along with the camshaft (3) and induces the close-spaced switches (8) to lead the close-spaced switches (8) to send a signal to the electric control gear, and the electric control gear commands a tool releasing mechanism to act the tool buttoning and tool releasing at the same time, thereby shortening the tool change time, increasing the operation efficiency, and ensuring that the whole tool change action is consecutive and reliable.
Description
Technical field
The utility model relates to a kind of machining center cutter-exchange mechanism.
Background technology
Existing mechanical machining center cutter-exchange mechanism is that the motor that joins with electric control gear is installed on bracing frame, motor is installed in camshaft on the bracing frame and the action of tool arm main shaft by actuator drives, the rotation of tool arm main shaft and move axially and can realize the tool changing action.In exchanging knives process, tool arm is at first detained cutter to the cutter on the tool magazine, drive tool magazine by electric control gear then and carry out the action of loose cutter, the action of present loose cutter drives the signal chains wheel by camshaft by the sprocket chain bar and responds to control, its shortcoming is that accumulated error inevitably appears in the assembling of a plurality of parts, make loose cutter action induction put in place untimely, the action of button cutter and loose cutter can not be carried out simultaneously, must wait for the loose cutter of certain hour ability after promptly detaining cutter, cause tool change time long, cause working (machining) efficiency low, move discontinuous.
Summary of the invention
The purpose of this utility model provides a kind ofly detains cutter and loose cutter can carry out, move the machining center cutter-exchange mechanism that links up, shortens tool change time, improves machined efficient simultaneously, overcomes the deficiencies in the prior art.
Machining of the present utility model center cutter-exchange mechanism, it comprises the motor 1 and camshaft 3 that is connected with motor 1 and tool arm main shaft 5 that is installed on the bracing frame 2, it is characterized in that: be provided with sensor block 6 and the proximity switch 8 that match and that join with electric control gear with sensor block 6 on cutter-exchange mechanism.
Machining of the present utility model center cutter-exchange mechanism, wherein said sensor block 6 is located on the retainer ring 4, and described retainer ring 4 is fixed on the end of camshaft 3.
Machining of the present utility model center cutter-exchange mechanism, wherein said proximity switch 8 is fixed on the support 7, and support 7 is connected with bracing frame 2 bolting.
Machining of the present utility model center cutter-exchange mechanism, the fixed installation on the wherein said support 7 is a slotted hole with bolt hole 13.
Machining of the present utility model center cutter-exchange mechanism, owing to be fixed with retainer ring 4 in the end of camshaft 3, on retainer ring 4, be fixed with sensor block 6, on bracing frame 2, be fixed with two proximity switch 8 that match and that join with electric control gear with sensor block 6, sensor block 6 rotates with camshaft 3 during work, and with proximity switch 8 induction, make proximity switch 8 send signal to electric control gear, and by the action of electric control gear instruction cutter-removing mechanism, button cutter and loose cutter are moved simultaneously, shortened tool change time, improved operating efficiency, made whole tool changing action link up reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is the local enlarged diagram of Fig. 1;
Fig. 3 is an A-A cross-sectional schematic shown in Figure 2;
Fig. 4 is a B-B cross-sectional schematic shown in Figure 2.
The specific embodiment
As shown in the figure: 2 is the bracing frame of cutter-exchange mechanism, and motor 1, tool arm main shaft 5, camshaft 3 are installed on bracing frame 2, and motor 1 drives camshaft 3 and 5 actions of tool arm main shaft during work, the rotation of tool arm main shaft 5 and move axially and can finish required tool changing action.End at camshaft 3 is fixed with retainer ring 4 by jackscrew 10, is inlaid with sensor block 6 at the cylindrical place of retainer ring 4, and with jackscrew 9 fixed block 6 is fixed on the retainer ring 4.Bracing frame 2 be fixed with L type support 7 with bolt 14, with nut 11 proximity switch 8 is fixed on the L type support 7, the termination of proximity switch 8 and sensor block 6 match, the lead 12 and the electric control gear that join with proximity switch 8 join.The bolt hole 13 that is used to install and fix is slotted hole, its objective is the relative distance of adjusting between proximity switch 8 and the sensor block 6.Two proximity switch 8 are housed on bracing frame 2, when one of them proximity switch and sensor block 6 inductions, can send a preparatory signal to electric control gear, when another proximity switch and sensor block 6 inductions, electric control gear instruction cutter-removing mechanism is made loose cutter action immediately, carry out simultaneously to guarantee that loose cutter action and button cutter move, save machining time.Be not limited only to be installed in retainer ring 4 places on the camshaft 3 at the sensor block described in this device 6, also can be installed on other moving components, get final product so long as sensor block 6 can be responded to mutually with proximity switch 8 and control loose cutter action by electric control gear.
Claims (4)
1, a kind of machining center cutter-exchange mechanism, it comprises the motor (1) and camshaft (3) that is connected with motor (1) and tool arm main shaft (5) that is installed on the bracing frame (2), it is characterized in that: the proximity switch (8) that is provided with sensor block (6) and matches with sensor block (6) and join with electric control gear on cutter-exchange mechanism.
