Technical Field

[0001] This utility model relates to the technical field of electric cylinder housing processing equipment, specifically a calibration device for electric cylinder housing processing. Background Technology

[0002] An electric cylinder is an actuator that converts the rotary motion of an electric motor into linear motion. It drives a screw or lead screw through a motor to make a piston or push rod move linearly, thereby achieving precise positioning and push-pull force control. Electric cylinder housing machining refers to the process of machining and manufacturing the outer shell of the electric cylinder, which is widely used in automation equipment, robots, precision instruments and other fields.

The two ends of the adjusting rod 681 are rotatably connected to the inside of the support frame 61 through bearing seats. One end of the pulley set 682 is located on the outside of the adjusting rod 681. Furthermore, the other end of the second pulley assembly 682 is located on the outside of the round rod 651, the gear 683 is fixed on the outside of the adjusting rod 681, the rack 684 is meshed with the outside of the gear 683, and the bottom end of the rack 684 is fixedly connected to the top end of the movable plate 63. The outside of the support rod 673 is rotatably connected to the second bevel gear 672 through a guide key, and the second bevel gear 672 is slidably connected to the support rod 673. This arrangement allows the second bevel gear 672 to be supported by the support rod 673 when rotating, and the second bevel gear 672 can slide along the support rod 673.

[0029] The connecting mechanism 67 has two sets, which are respectively located at the left and right ends of the control mechanism 66, and are used to connect the control mechanism 66 with the two sets of moving mechanisms 65.

[0030] The rotation angle of bevel gear 671 is fixed. Therefore, when bevel gear 672 moves away from bevel gear 671 and engages with it, it can maintain engagement with bevel gear 671 when it moves back.

[0031] The working principle is as follows:

[0032] First, before use, place the workpiece to be processed on the fixing device 4 and the supporting device 5, and wait for processing;

[0033] Secondly, during use, the end face of the electric cylinder housing workpiece is processed by a processing device, including enlarging holes, chamfering, and tapping.

[0034] Third, during processing, since the processing device comes into direct contact with the workpiece, vibrations will occur during the processing. Therefore, after processing for a period of time, the position of the workpiece needs to be calibrated and adjusted to ensure processing quality.

[0035] Fourth, start motor 663. Motor 663 drives worm 662 to rotate. When worm 662 rotates, it drives worm wheel 664 to rotate. When worm wheel 664 rotates, it drives rotating rod 665 to rotate. When rotating rod 665 rotates, it drives bevel gear one 671 to rotate. When bevel gear one 671 rotates, it drives bevel gear two 672 to rotate. When bevel gear two 672 rotates, it drives bevel gear three 674 to rotate. When bevel gear three 674 rotates, it drives connecting rod 654 to rotate.

[0036] Fifth, when the connecting rod 654 rotates, it drives the round rod 651 to rotate through the pulley group 655. When the round rod 651 rotates, it drives the threaded sleeve 652 to rotate. When the threaded sleeve 652 rotates, it drives the movable block 653 to move. When the movable block 653 moves, it drives the fixed device 4 to move to the right. When the round rod 651 rotates, it drives the adjusting rod 681 to rotate through the pulley group 682. When the adjusting rod 681 rotates, it drives the gear 683 to engage. When the gear 683 rotates, it drives the rack 684 to move. When the rack 684 moves, it drives the movable plate 63 to move. When the movable plate 63 moves, it drives the laser displacement sensor 64 to move.

[0037] Sixth, when the laser displacement sensor 64 moves to the same level as the workpiece, the workpiece is monitored to determine whether it has shifted during the processing. If it has shifted, the fixing device is adjusted to readjust the position of the workpiece. After the adjustment is completed, the laser displacement sensor 64 is raised by the motor 663, and the fixing device 4 moves the workpiece to the front of the processing device 2 to continue processing.

[0038] Seventh, during the processing, if only one processing device is working, the other device needs to be disconnected to save resources. Therefore, electromagnet 675 needs to be activated. Electromagnet 675 generates a magnetic force on iron block 676, causing iron block 676 to move downwards. When iron block 676 moves, it drives bevel gear 2 672 to move downwards, causing bevel gear 2 672 to disengage from bevel gear 1 671 and bevel gear 3 674, thus canceling the connection. When rotating rod 665 rotates, it will not affect the movement of this group. When bevel gear 2 672 moves downwards, it compresses spring 677. When reconnection is required, electromagnet 675 is turned off, and spring 677 pushes bevel gear 2 672 upwards, re-engaging with bevel gear 1 671 and bevel gear 3 674, thus maintaining the connection and waiting for use.

[0039] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0040] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
