Description

Technical Field

[0001] The invention relates to the technical field of tool welding, in particular to a machining tool for numerical control tool welding. Background Art

[0002] CNC tools are tools used for cutting in mechanical manufacturing. CNC tools are usually made of a super-hard cutter head made of an alloy and fixed to a tool handle made of ordinary metal by welding, so that the alloy and the tool form the required tool for part processing. The welding of the tool usually uses an electromagnetic heating ring to heat and weld the tool and the cutter head.

[0003] At present, in the prior art, a Chinese patent with a publication number of CN216065907U discloses a machining tool for CNC tool welding. The device uses a pressing structure and a clamping mechanism arranged on a bottom plate so that after the tool is fixed to a fixed seat, the pressing structure and the clamping mechanism can restrict the tool head part of the tool to the head of the tool, thereby preventing the flux between the tool and the tool head from melting when the electromagnetic heating ring heats the head of the tool, causing the tool head and the tool to be misaligned.

[0004] However, when the device is actually used, when taking out the tool, if it is taken out manually, it is necessary to wait for the tool to cool down to prevent burns to the staff. If it is taken out by a robot, it is necessary to manually release the fixation of the tool. The tooling efficiency is low, the cost of using the robot is high, and programming is also more complicated. In view of this, the present invention proposes a machining tool for CNC tool welding.

The inner surface of the square seat 5241 is rotatably connected with a threaded sleeve 5242.

When the output shaft of the stepper motor 522 rotates clockwise, the screw rod 523 is driven to rotate clockwise. Since the T rod 5266 is inserted into the jack of the threaded sleeve 5242, the threaded sleeve 5242 will not rotate relative to the square seat 5241, thereby driving the square seat 5241 to move, so that the connecting block 525 drives the fixed arm 53 to move, and the cylinder clamp 58 moves in the direction of the welded tool, and then the welded tool is clamped by the cylinder clamp 58, and then the electric cylinder 51 is started to move the fixed arm 53 upward, and the welded tool is pulled out, thereby achieving the effect of removing the welded tool.

[0028] Furthermore, in order to be able to automatically discharge the tool handle 54, specifically, the auxiliary feeding assembly 57 includes a connecting rod 571, the connecting rod 571 is fixedly connected to the cylinder clamp 58, the end of the connecting rod 571 away from the cylinder clamp 58 is fixedly connected to a sliding ring 572, the sliding ring 572 is elastically connected to the inner wall of the fixed arm 53 through a connecting spring, the lower side of the sliding ring 572 is fixedly connected to an L rod 573, the end of the L rod 573 away from the sliding ring 572 is fixedly connected to a blanking plate 574, and the blanking plate 574 is slidably connected to the tool handle 54. It is connected to the outer wall of the fixed seat 521. After the welded tool is pulled out, the output shaft of the stepper motor 522 is started to rotate clockwise, and the cylinder clamp 58 conflicts with the fixed plate 8. At this time, the connecting rod 571 drives the sliding ring 572 to squeeze the connecting spring, and the L rod 573 drives the unloading plate 574 to move.

When the output shaft of the stepper motor 522 rotates counterclockwise, under the limiting effect of the elastic telescopic ratchet rod 5244 on the threaded sleeve 5242, the threaded sleeve 5242 can drive the square seat 5241 to reset.

[0031] It should be noted that the above-mentioned electrical components are all existing technology products. Technical personnel in this field select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all universal standard parts or components known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. The applicant does not make specific restrictions here.

[0032] When in use, first pass the knife handle 54 through the positioning sleeve 25 so that the knife handle 54 is fixed by the chuck 23, and then start the lifting assembly 63 to move the electromagnetic heating ring 64 upward to a position parallel to the top of the knife handle 54, so as to heat the knife handle 54 and the knife head body 4, and then start the cylinder on the support frame 61 to move the welding head 62 to the abutment between the knife handle 54 and the knife head body 4, and then start the drive motor 21.

Since the T rod 5266 is inserted into the jack of the threaded sleeve 5242, the threaded sleeve 5242 will not rotate relative to the square seat 5241, thereby driving the square seat 5241 to move, causing the connecting block 525 to drive the fixed arm 53 to move, causing the cylinder clamp 58 to move toward the direction of the welded tool, and then clamping the welded tool through the cylinder clamp 58, and then starting the electric cylinder 51 to move the fixed arm 53 upward, and the welded tool is pulled out; At the same time, after the welded tool is pulled out, the output shaft of the stepper motor 522 is started to rotate clockwise, and the cylinder clamp 58 is in conflict with the fixed plate 8. At this time, when the connecting rod 571 drives the sliding ring 572 to squeeze the connecting spring, the L rod 573 drives the blanking plate 574 to move. When the opening of the blanking plate 574 is aligned with the opening of the fixed arm 53, the tool handle 54 can fall from the placement groove of the fixed arm 53 into the placement rotation mechanism 2; At the same time, when the knife handle 54 can fall from the placement groove of the fixed arm 53 into the placement rotation mechanism 2, the blocking rod 56 moves in the direction of the knife handle 54 during the process of the unloading plate 574 moving the extrusion wheel, and blocks and limits the subsequent knife handle 54 to prevent the falling knife handle 54 from being subjected to the extrusion force, thereby enabling the falling knife handle 54 to fall quickly without getting stuck. During the movement of the unloading plate 574, the cross plate 5262 is squeezed, driving the cross bar 5261 to move, so that the fixed arm 53 can be fixed. The fixed ring 5263 squeezes the return spring, thereby driving the hinged rod 5265 to move, pulling the T-rod 5266 out of the socket of the threaded sleeve 5242. At this time, when the output shaft of the stepper motor 522 rotates clockwise, the threaded sleeve 5242 rotates relative to the square seat 5241, so that the square seat 5241 will no longer move, and the fixed arm 53 stops moving, achieving a stable positioning effect, so that the tool handle 54 can stably fall into the placement and rotation mechanism 2, and the welded tool can stably fall into the collection box 102.
