Referring to fig. 1 to 10, the present invention provides a fixing tool for drilling and tapping a door and window corner connector, including:
a base 100 connected to a drilling and tapping machine (not shown);
a turntable 200 rotatably connected to the spindle 110 provided in the middle of the base 100; and

Specifically, the two sets of gripping mechanisms 300 constitute two stations (loading and unloading station and processing station) spaced 180 ° apart in the horizontal plane, which rotate synchronously with the turntable 200. In operation, when the turntable 200 rotates on the spindle 110 to enable the fifth magnetic block 321 of one set of the clamping mechanism 300 to face the first magnetic block 111, due to the fact that the magnetic poles of the fifth magnetic block are different from those of the first magnetic block 111 and attract each other, the connecting rod 320 is drawn by magnetic force to approach the first magnetic block 111 and open the corresponding pair of movable clamps 310, and at the moment, an angle code to be drilled and tapped is placed between the pair of movable clamps 310 to complete feeding; the fifth magnetic block 321 of the other set of clamping mechanism 300 is just opposite to the second magnetic block 112, and due to the same magnetic poles, the fifth magnetic block and the second magnetic block are mutually repelled, and the connecting rod 320 is far away from the second magnetic block 112 under the action of magnetic repulsion and closes the corresponding pair of movable clamps 310; then, the turntable 200 horizontally rotates 180 degrees, so that the two stations are interchanged, the fifth magnetic block 321 of the previous set of clamping mechanism 300 is separated from the attraction range of the first magnetic block 111 and enters the repulsion range of the second magnetic block 112 until the fifth magnetic block is opposite to the second magnetic block 112, and the pair of movable clamps 310 with the corner codes placed therebetween are closed under the repulsion action of magnetic force so as to clamp the corner codes, so that the corner codes are drilled and tapped by a tool bit of the drilling and tapping all-in-one machine; meanwhile, the fifth magnetic block 321 of another previous set of clamping mechanism 300 is separated from the repulsive force range of the second magnetic block 112 and enters the attractive force range of the first magnetic block 111 until the attractive force range of the first magnetic block 111 is opposite to the first magnetic block 111, and at this time, the corresponding pair of movable clamps 310 are opened for second feeding of corner connectors; after the drilling and tapping of the previous corner brace is finished, the rotary table 200 horizontally rotates 180 degrees again, so that the two stations are exchanged for the second time, the second corner brace is clamped to enter the machining station, the previous corner brace is loosened to return to the loading and unloading station, the corner brace is taken down, a new corner brace is placed at the same time to finish blanking and loading, and then continuous machining operation is carried out according to the operation. That is, through the rotation of the turntable 200, the two sets of clamping mechanisms 300 can be opened and closed respectively under the magnetic force action of the first and second magnetic blocks with different magnetic poles, so that stations are exchanged, the purpose of simultaneously performing machining and loading and unloading is achieved, and the machining efficiency of the corner connector is improved.
The clamping mechanism 300 comprises a fixing clamp 330, a plurality of pin shafts 331 (shown in detail in fig. 8) are arranged on the side surface of the fixing clamp 330, and the pin shafts 331 are in plug connection with a plurality of sleeves 210 (shown in detail in fig. 5) arranged on the top surface of the rotary table 200, so that the fixing clamp 330 is suspended and is not attached to the top surface of the rotary table 200, and the feeding of a tool bit during the angle code drilling and tapping process is facilitated; the fixing clip 330 is u-shaped, one end of the fixing clip far away from the mandrel 110 is provided with a notch 332, the parts of the fixing clip 330 at the two sides of the notch 332 are closed to the middle to form inclined arms 333 which are distributed in an inner splay shape, and a through cross-shaped sliding groove is arranged in the inclined arms 333 along the length direction; the two ends of the movable clamp 310 are provided with an inclined back surface (shown in detail in fig. 9) on the same side, one end of the inclined back surface is provided with a T-shaped strip 311 connected with the cross sliding groove in a sliding manner, and the other end of the inclined back surface is provided with a guide hole 312 penetrating through the front surface of the movable clamp 310; the connecting rod 320 includes a first guide rod 322 and a second guide rod 323 (shown in detail in fig. 10) which are connected to each other perpendicularly and form a T-shaped structure, one end of the first guide rod 322, which is far away from the second guide rod 323, slides through a through hole 334 formed in the bottom of the fixing clip 330 and then is fixedly connected to the fifth magnet 321, and the second guide rod 323, which slides through the guide hole 312, extends into the cross sliding slot. Specifically, by the horizontal rotation of the turntable 200, the fifth magnetic block 321 of one set of clamping mechanism 300 faces the first magnetic block 111, and the first magnetic block 321 and the first magnetic block 111 are opposite to each other, and the magnetic poles of the first magnetic block and the first magnetic block are different and mutually attracted, so that the first guide rod 322 is driven to slide in the through hole 334, so that the distance between the fifth magnetic block 321 and the first magnetic block 111 is gradually reduced (but not attracted together, that is, a gap is formed at the end), meanwhile, the second guide rod 323 follows the first guide rod 322 and drives the movable clamp 310 to slide in the cross chute through the guide hole 312 so as to be accommodated in the gap 332, so that the pair of movable clamps 310 is opened to facilitate the placement of the angle code, and then after the turntable 200 rotates by 180 ° in the horizontal plane, the fifth magnetic block 321 faces the second magnetic block 112, and the first guide rod 322 slides reversely along the through hole 334 under the repulsive force so that the distance between the fifth magnetic block 321 and the second magnetic block 112 is gradually increased, and the second guide rod 323 follows the first guide rod 322 and drives the movable clamp 310 to reversely slide in the cross chute 312 so as to extend out of the gap 332, thereby clamping the previously placed angle code; and the opening and closing actions of the other clamping mechanism 300 are just opposite, so that station exchange is realized under the condition that the rotary table 200 rotates, and the simultaneous processing, loading and unloading can be ensured.
Referring to fig. 9, in order to adapt to a specific right-angle structure of the corner connector, an upper protrusion 313 and a lower protrusion 314 are arranged at the rear of the front of the movable clamp 310 for clamping the corner connector, a gap is left between the upper protrusion 313 and the lower protrusion 314 to form a slot for clamping the corner connector, and the front end (the end far away from the guide hole 312) of the lower protrusion 314 is obliquely arranged to increase the entrance of the slot, so that the corner connector can be conveniently clamped. That is to say, hold the angle sign indicating number through the draw-in groove card, the laminating is better between activity clamp 310 and the angle sign indicating number, can improve the stability of this fixed frock to guarantee the position accuracy of the through-hole or the screw hole that the angle sign indicating number was processed out.
Referring to fig. 7, the clamping mechanism 300 further includes a compression spring 340, the compression spring 340 is sleeved on the first guide rod 322, and two ends of the compression spring 340 are respectively connected with the second guide rod 323 and the bottom of the fixing clip 330 in an abutting manner. In the horizontal rotation process of the rotary table 200, when the fifth magnetic block 321 is not opposite to the first magnetic block 111 and the second magnetic block 112 and is completely separated from the magnetic action range, the second guide rod 323 enables the movable clamp 310 to be in a half-open and half-closed state through the reset force action of the pressure spring 340, so that the corner codes are pre-clamped, and the shaking caused by the rotation of the rotary table 200 is reduced; meanwhile, when the fifth magnetic block 321 and the second magnetic block 112 are aligned, repulsive force between the fifth magnetic block 321 and the second magnetic block is superposed with reset force of the pressure spring 340, so that clamping force of the diagonal brace can be enhanced, stability of the fixing tool is further improved, and position accuracy of a through hole or a threaded hole machined by the diagonal brace is guaranteed.
Referring to fig. 2 and 5, the top surface of the rotary table 200 is provided with a u-shaped pre-insertion slot 220, and the pre-insertion slot 220 is located below the notch 332 for placing an angle to achieve pre-fixing. During the clamping, the angle sign indicating number can insert earlier and realize fixing in advance in slot 220, later presss from both sides tightly by activity clamp 310 clamp, when saving the angle sign indicating number clamping usefulness, is favorable to the improvement of angle sign indicating number machining efficiency, and slot 220 can reduce rocking of angle sign indicating number in advance simultaneously, guarantees its stability in drilling tapping course of working.
Referring to fig. 2, two side faces of the regular prism adjacent to the side face where the first magnetic block 111 is located are provided with third magnetic blocks 113, and the magnetic poles of the third magnetic blocks 113 are the same as those of the first magnetic blocks 111; the two side faces of the regular prism, which are close to the side face where the second magnetic block 112 is located, are provided with fourth magnetic blocks 114, and the magnetic poles of the fourth magnetic blocks 114 are the same as those of the second magnetic block 112; the first magnetic block 111 and the second magnetic block 112 are equal in size and large in size, and have strong magnetic force; the third magnetic block 113 and the fourth magnetic block 114 have the same volume and are smaller, and the magnetic force is weaker. When the fifth magnetic block 321 and the first magnetic block 111 (the second magnetic block 112) are in positive pairing, the attractive force (repulsive force) between the fifth magnetic block 321 and the first magnetic block 111 (the second magnetic block 112) is strongest, then along with the horizontal rotation of the turntable 200, the fifth magnetic block 321 gradually departs from the range of stronger attractive force (repulsive force) of the first magnetic block 111 (the second magnetic block 112) and enters the range of weaker attractive force (repulsive force) of the third magnetic block 113 (the fourth magnetic block 114), at this time, the reset force of the compression spring 340 gradually plays a main role to pre-clamp the corner code, and finally, when the fifth magnetic block 321 leaves the range of attractive force (repulsive force) of the third magnetic block 113 (the fourth magnetic block 114), the clamping of the corner code is completely realized by the reset force of the compression spring 340. That is, along with the horizontal rotation of the turntable 200, the attraction (repulsive force) applied to the fifth magnetic block 321 is changed from strong to weak to zero, so that the clamping force of the corner brace is controlled, and the stability of the corner brace in the processes of loading and unloading and drilling and tapping is improved.
In this embodiment, the regular prism is a regular octagonal prism, and the first to fifth magnetic blocks are all neodymium iron boron magnets. The turntable 200 horizontally rotates 45 degrees, and the fifth magnetic block 321 is changed from a state of being opposite to the first magnetic block 111 (the second magnetic block 112) to a state of being opposite to the third magnetic block 113 (the fourth magnetic block 114); the turntable 200 rotates horizontally by 90 °, the fifth magnet 321 is not affected by magnetic force at all, and the restoring force of the compression spring 340 plays a major role at this time. Neodymium iron boron magnet magnetic force is strong, can effectively guarantee the magnetic force effect between first to the fifth magnetic path to improve the stability of this fixed frock once more.
