[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Figures 1 to 4 As shown, the present utility model provides a technical solution: a motor with quick positioning and offset compensation, which is used for the adjustment of the die extension rod 4 (hob extension rod), generally for the quick Y-direction adjustment and quick positioning of the rotation direction of the die extension rod 4.

[0025] It includes: a housing 1, the housing 1 is provided with a driving area 101, an output area 102 and a control area 103. Among them, the control area 103 is communicated with the driving area 101. A circuit board 7 is fixedly connected to the control area. The circuit board 7 is fixedly connected with a plurality of switches extending to the outside of the housing 1. The control area 103 is mainly an open slot communicated with the driving area 101, which is sealed by a cover plate. A plurality of through slots communicated with the switches are arranged on the cover plate, and the switches extend to the outside of the housing 1 through the through slots.

[0026] The housing 1 is fixedly connected with a communication interface 8 that cooperates with the circuit board 7. By connecting to an external system through the communication interface 8, the data of the motor can be downloaded and recorded, which is convenient for the update of subsequent production data.

[0027] The output area 102 is provided with a through hole that cooperates with the die extension rod 4. The die extension rod 4 passes through the through hole and extends into the output area 102. A driving component is fixed in the driving area 101. The driving component extends to the output area 102 and cooperates with an adjusting block 2. The driving component and the adjusting block 2 cooperate to drive the die extension rod 4 for Y-direction adjustment.

[0028] The driving component includes: a driving motor 3 fixedly arranged in the driving area 101. The driving motor 3 is cooperated with a speed reducer. The speed reducer is fixedly connected with a driving block 5 by bolts. A first bearing 11 is connected between the outer side wall of the driving block 5 and the driving area 101. The first bearing 11 can reduce the friction between the driving block 5 and the driving area 101 and improve the driving effect.

[0029] The driving block 5 and the adjusting block 2 are connected by a ball screw mounting method. The adjusting block 2 is provided with a guiding portion 201. A plurality of guide rods 6 are fixedly connected to the guiding portion 201. The output area 102 and the driving area 101 are both provided with guiding grooves that cooperate with the guide rods 6. Through the cooperation of the motor and the reducer, the motor speed is reduced while the overall transmission torque is increased, and the adjusting block 2 is driven under the action of the guide rods 6 and the guiding grooves to convert the rotational motion into a reciprocating linear motion.

[0030] The guide rod 6 is fixedly connected with a limiting portion. The limiting portion is fixedly connected with a trigger block 9. The lower surface of the circuit board 7 is fixedly connected with a trigger switch 10 that cooperates with the trigger block 9. When the adjusting block 2 moves in a reciprocating linear motion, the moving distance of the adjusting block 2 is controlled through the cooperation of the trigger block 9 and the trigger switch 10.

[0031] A center point 12 is arranged inside the adjusting block 2. The center point 12 is rotatably connected to the inner side wall of the adjusting block 2 through a second bearing. The adjusting block 2 drives the center point 12 to contact the end of the die extension rod 4, driving the die extension rod 4 to perform local fine adjustment in the Y direction.

[0032] The adjusting block 2 is provided with a rotating groove that cooperates with the center point 12. The center point 12 is rotatably arranged in the rotating groove. The output area 102 is fixedly connected with a metal proximity switch sensor 13 that cooperates with the die extension rod 4. The die extension rod 4 is provided with an induction groove that cooperates with the metal proximity switch. Through the cooperation of the metal proximity switch sensor 13 and the induction groove of the die extension rod 4, it is convenient to position the die extension rod (hob extension rod) in real time. An induction groove is opened on the circumferential surface of the die extension rod 4. The induction groove is consistent with the circumferential zero angle of the die edge processing. The metal proximity switch sensor is used to quickly position the mechanical zero angle when the die rotates, thereby realizing the quick positioning of the die rotation in the X direction.

[0033] The overall structure is extremely miniaturized, which is convenient for users to use and can operate independently at the same time. A display screen is provided on the motor, which is used to display the state of compensation adjustment in real time and display the real-time state when manually adjusting with buttons.

[0034] First, in terms of structural design, a precise groove (induction groove) is machined on the hob extension rod. A micro-precision metal proximity switch sensor 13 is placed beside the shaft. When the non-groove part of the shaft passes by the sensor, the metal surface is very close to the sensor, and the sensor outputs a high level. When the groove passes by the sensor, the metal surface is far away from the sensor, and the sensor outputs a low level. Thus, the position of the groove is detected, and this position is used as the angle when the hob is installed.

[0035] The material moves uniformly in the X direction (the material advancing direction) under the traction of the power structure. The hob rotates synchronously, and the hob is in a tightly pressed state with the material. When the cutting edge on the hob touches the material, a cut will be left on the material, forming the product cutting shape we need according to the design.

[0036] Complex products require multiple multi-layer cutting operations, which necessitate the coordinated operation of multiple cutting stations. This gives rise to an alignment problem, namely that the cuts made by the previous station must be precisely aligned with those of the subsequent station. Otherwise, misaligned cuts will result in a large number of defective products.

[0037] This alignment includes alignment along the material advancement direction (X-direction) and alignment along the hob axial direction (Y-direction). When misalignment occurs in the X-direction, defective phenomena will emerge. If the hob in this station lags in the X-direction, the cut will be lagged compared to the correct position; if the hob in this station is ahead in the X-direction, the cut will be ahead compared to the correct position.

[0038] As Figure 4 shown, when misalignment occurs in the Y-direction, defective phenomena will occur. If the hob in this station is biased upward, the cut will be biased upward compared to the correct position; if the hob in this station is biased downward, the cut will be biased downward compared to the correct position.

[0039] Since sensor detection and hob control are processed by different modules, there is a communication delay in between, and there is also a certain lag in the output of the sensor detection signal. Therefore, precise positioning of the zero angle needs to be completed in two steps. First, let the hob rotate rapidly in the forward direction.

[0040] When the sensor detects a signal, stop the hob after a short delay. At this time, the groove has passed a short distance beyond the sensor position. Then, the hob rotates in the reverse direction at a low speed, and the groove slowly approaches the sensor. When the sensor detects the signal again, immediately stop the hob. This position is marked as the zero angle position.

[0041] These two-step adjustments are equivalent to a rough adjustment for roughly finding the zero point position in the first step and a fine adjustment for precisely positioning the zero angle position in the second step. This can effectively avoid positioning errors and shorten the adjustment time, achieving the purpose of quickly positioning the zero angle.

[0042] After the rotational direction angle of the X-direction is positioned, the system processing can have the initial accuracy, so that the cuts of the previous station and this station can simultaneously enter the camera's field of view, and the camera can identify and calculate the errors in the XY-directions.

[0043] When the camera detects an error in the X-direction, adjust the rotational speed of the hob according to the error magnitude to eliminate the error value in the X-direction.

[0044] When the camera detects an error in the Y-direction, the motor adjusts the position of the hob through the drive assembly. When the cut is biased to the right, move the hob to the left by the corresponding distance; conversely, when the cut is biased to the left, move the hob to the right by the corresponding distance. Thus, the error value in the Y-direction can be eliminated.

[0045] For each cut processing by the camera, it will capture, calculate, and output the deviation value, and then adjust the hob state in real time, thereby forming a high-speed closed-loop control system.

[0046] The embodiments disclosed in the present utility model are preferred embodiments, but are not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present utility model based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present utility model, they are within the protection scope of the present utility model.
