Description

Technical Field

[0001] This utility model relates to the field of encoder manufacturing technology, specifically to an encoder laser etching positioning device. Background Technology

[0002] An encoder is a device that encodes and converts signals or data into a signal form that can be used for communication, transmission, and storage. It is widely used in industrial automation, robotics, aerospace, transportation, medical equipment, electronic products, packaging and printing, military and security fields to measure and control the rotational speed, position, and angle of equipment, thereby enabling automated production and processing. During the production process of an encoder, the surface of its dial is usually laser-etched to ensure the accuracy of the scale.

[0003] Most current positioning fixtures for encoder laser etching are fixed on the worktable and are designed for a single model. They have a small range of adjustment. When fixing encoders with large dimensional deviations, the fixture needs to be changed. The replacement process is cumbersome and time-consuming, which reduces the etching efficiency.

A polygonal adjusting sleeve is rotatably connected inside the fixed base. An adjusting screw is threadedly connected to the inner surface of the polygonal adjusting sleeve. One end of the adjusting screw passes through the outer surface of the rotating cylinder and is rotatably connected to one end of the adjusting column. A movable turntable is slidably connected to the outer surface of the polygonal adjusting sleeve. One end of the movable turntable is inserted into the interior of the fixed base.

[0009] As a further preferred embodiment of this technical solution, a limiting ring is fixedly connected to the outer surface of the adjusting column, and the outer surface of the limiting ring abuts against one side of the partition plate.

[0012] This utility model provides an encoder laser etching positioning device, which has the following beneficial effects:

[0013] (1) This utility model drives the adjustment column to move by rotating the No. 1 adjustment screw.

The positioning plate clamps and positions the outer surface of the encoder. During the etching of the scale, the servo motor drives the rotating cylinder to rotate intermittently, which makes it easier for the laser etching head to etch the scale on the encoder. This enables the encoder of different sizes to be quickly positioned and fixed. The efficiency of etching the scale is improved by the cooperation of the servo motor.

[0014] (2) This utility model slides the movable turntable along the outer surface of the polygonal adjustment sleeve, so that one end of the movable turntable is inserted into the fixed seat to limit the polygonal adjustment sleeve, so that the No. 1 adjustment screw is fixed together, thereby improving the stability of the positioning plate after fixing the encoder and improving the positioning strength.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1-3 As shown, in this embodiment, an encoder laser etching positioning device includes a worktable 1, a positioning seat 2 fixedly connected to the top of the worktable 1, a rotating cylinder 3 rotatably connected inside the positioning seat 2, a partition plate 4 fixedly connected inside the rotating cylinder 3, two guide holes 5 penetrating one side of the partition plate 4 and one end of the rotating cylinder 3, two driven rods 6 slidably connected inside the four guide holes 5, an adjusting column 7 slidably connected inside the partition plate 4, and multiple connecting rods 8 rotatably connected to the outer surface of the adjusting column 7, the other ends of the multiple connecting rods 8 being rotatably connected to one side of the two driven rods 6, and a positioning plate 9 fixedly connected to one end of each of the two driven rods 6, the outer surface of the rotating cylinder 3 being fixedly connected to the positioning plate 9. A driven gear ring 10 is fixedly connected, and a driving gear 11 meshes with the outer surface of the driven gear ring 10. A servo motor 12 is driven and connected to one end of the driving gear 11. The outer surface of the servo motor 12 is fixedly connected to the inside of the positioning seat 2. By setting an adjustment column 7, the position of the driven rod 6 can be adjusted by pulling the connecting rod 8 during the movement, so as to achieve the clamping and positioning effect of the positioning plate 9. By setting a guide through hole 5, the positioning effect of the driven rod 6 can be achieved. By setting the driven gear ring 10, the driving gear 11 and the servo motor 12, the rotating cylinder 3 can be driven to rotate, so as to automatically adjust the encoder etching position and improve the etching efficiency.

[0022] like Figure 2 and Figure 3As shown, a fixed base 14 is fixedly connected to the other end of the rotating cylinder 3 at the center position. A polygonal adjusting sleeve 15 is rotatably connected inside the fixed base 14. A first adjusting screw 13 is threadedly connected to the inner surface of the polygonal adjusting sleeve 15. One end of the first adjusting screw 13 passes through the outer surface of the rotating cylinder 3 and is rotatably connected to one end of the adjusting column 7. A movable turntable 16 is slidably connected to the outer surface of the polygonal adjusting sleeve 15. One end of the movable turntable 16 is inserted into the fixed base 14. By setting up the polygonal adjusting sleeve 15, the first adjusting screw 13 can be moved during rotation to adjust the position of the adjusting column 7. By setting up the movable turntable 16, the first adjusting screw 13 can be easily adjusted by cooperating with the polygonal adjusting sleeve 15, and the first adjusting screw 13 can be fixed by cooperating with the fixed base 14.

[0023] like Figure 3 As shown, one end of the polygonal adjusting sleeve 15 is fixedly connected to the limiting plate 24, and one end of the movable turntable 16 is interference-fitted with the inside of the fixed base 14. By setting the limiting plate 24, the movable turntable 16 can be prevented from falling off the polygonal adjusting sleeve 15. By setting the interference fit between one end of the movable turntable 16 and the inside of the fixed base 14, the connection strength can be improved.

[0024] like Figure 3 As shown, the other ends of the two driven rods 6 are fixedly connected to a limiting plate 17. The outer surfaces of the two limiting plates 17 are in contact with one side of the partition plate 4. By setting the limiting plate 17, the driven rods 6 can be positioned when they move to prevent tilting.

[0025] like Figure 3 As shown, a limiting ring 18 is fixedly connected to the outer surface of the adjusting column 7. The outer surface of the limiting ring 18 abuts against one side of the partition plate 4. During the movement of the adjusting column 7, the limiting ring 18 and the partition plate 4 can block the movement of the adjusting column 7 and prevent over-adjustment.

[0026] like Figure 1 and Figure 4 As shown, a mounting bracket 19 is fixedly connected to the top of the workbench 1. An adjusting cylinder 21 is slidably mounted on the top of the mounting bracket 19. A laser etching head 22 is fixedly connected to the telescopic end of the adjusting cylinder 21. By setting the adjusting cylinder 21, the position of the laser etching head 22 can be adjusted, making it convenient to etch different positions.

[0027] like Figure 4 As shown, a second adjusting screw 20 is rotatably connected inside the mounting bracket 19. The outer surface of the second adjusting screw 20 is threadedly connected to the outer surface of the adjusting cylinder 21. A control box 23 is fixedly connected to the top of the worktable 1. By setting the second adjusting screw 20, the distance between the encoder and the laser etching head 22 can be controlled.

[0028] This utility model provides an encoder laser etching positioning device, the specific working principle of which is as follows:

[0029] During encoder installation and positioning, the operator pulls the movable turntable 16 out of the fixed base 14, then rotates the movable turntable 16 to drive the polygonal adjusting sleeve 15 to rotate. During the rotation of the polygonal adjusting sleeve 15, it pushes the first adjusting screw 13 to move, which in turn pushes the adjusting column 7 to move. During the movement of the adjusting column 7, it drives the connecting rod 8 to move, causing the connecting rod 8 to pull the driven rod 6 to move within the guide through hole 5, allowing the positioning plate 9 to clamp and position the outer surface of the encoder. After positioning, the operator inserts the movable turntable 16 along the surface of the polygonal adjusting sleeve 15 into the fixed base 14 for fixation. During etching, the operator adjusts the position of the laser etching head 22 using the second adjusting screw 20 and the adjusting cylinder 21. After adjustment, the operator starts the laser etching head 22 and the servo motor 12 through the control box 23. The servo motor 12 drives the rotating cylinder 3 to rotate intermittently in coordination with the laser etching head 22 through the driving gear 11 and the driven gear ring 10, etching different positions.

[0030] 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.
