Technical Field

[0002] An encoder is a device that converts motion into electrical signals for counting. By processing the electrical signals, the position and speed of an object can be accurately determined. Encoders are widely used in various types of mechanical equipment.
[0003] Whether the encoder is produced and shipped out of the factory or in use, it may still be damaged. Therefore, detecting the quality of the encoder is an important task. The quality of the encoder is affected by the detection method and the accuracy of the detection device. The traditional measurement method is to manually rotate the output end of the encoder. Measuring the quality of the encoder requires repeated actions many times, and the origin position needs to be set. It is distinguished based on whether there is a difference between the origin position and the initial position displayed. The traditional method of manually rotating the output end of the encoder is not accurate and is prone to measurement errors.
[0004] Therefore, an encoder testing device is proposed. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figures 1 to 3 The utility model provides an encoder 9 testing device, and the technical solution is as follows:
[0021] An encoder testing device comprises a bracket 1, a motor 2, a screw 3, a slider 4, and a gear 5. The motor 2 is fixedly mounted on the top wall of the bracket 1. A screw 3 is rotatably mounted on the top wall of the bracket 1. One end of the screw 3 is fixedly connected to the output end of the motor 2. The slider 4 is threadedly connected to the screw 3. The gear 5 is rotatably mounted on the side wall of the slider 4. A slide rail 7 is fixedly mounted on the top wall of the bracket 1. An encoder 9 is slidably mounted on the slide rail 7. The rotating shaft of the encoder 9 is fixedly connected to the gear 5 through a coupling 11. Rack 6, a controller 8 is fixedly installed on the top wall of the bracket 1, and the controller 8 controls the motor 2 to rotate forward and reverse. The motor 2 is electrically connected to the controller 8 through wires. The controller 8 controls the motor 2 to rotate forward and reverse, and controls the number of rotations of the motor 2. The motor 2 drives the screw 3 to rotate forward and reverse, so that the slider 4 reciprocates along the screw 3, and the slider 4 drives the gear 5 to perform linear reciprocating motion. Since the gear 5 and the slider 4 are rotatably installed, relative rotation can be generated, and the gear 5 is meshed with the rack 6, so that the gear 5 also rotates when performing linear reciprocating motion, thereby driving the rotating shaft of the encoder 9 to rotate.
[0022] like Figure 1 As shown, the encoder 9 is connected to the controller 8 via wires, and the controller 8 reads and records the initial value of the encoder 9 and displays the current value of the encoder 9 in real time.
[0023] The motor 2 is electrically connected to the controller 8 through wires, and the controller 8 controls the forward and reverse rotation of the motor 2 and the number of revolutions of the motor 2. The controller 8 adjusts the initial position and the reciprocating travel distance of the slider 4 so as to record the initial position and current position of the encoder 9 when the slider 4 reciprocates to judge whether the encoder 9 is good or bad.
[0024] like Figure 2 and Figure 3 As shown, a sliding frame 10 is slidably installed on the sliding rail 7, and the encoder 9 is detachably installed on the sliding frame 10 by screws. A clamping assembly is provided on the sliding frame 10, and the clamping assembly includes a fastening bolt 12 and a push plate 13. The fastening bolt 12 is threadedly installed on the sliding frame 10, and the push plate 13 is rotatably installed on one end of the fastening bolt 12.
[0025] When measuring the encoder 9, not only one encoder 9 needs to be tested, but the encoder 9 also needs to be replaced for testing. At this time, the fastening bolt 12 needs to be rotated to move the push plate 13 to cancel the pressure on the encoder 9, and then take it away and put in another encoder 9 for testing, and then rotate the fastening bolt 12 to clamp the encoder 9.
[0026] This device can test the pulse encoder 9 (incremental type) and the absolute value encoder 9. The controller 8 reads the value of the (incremental type) pulse encoder 9 through orthogonal encoding or reads the value of the absolute value encoder 9 through CAN communication, records the initial value of the encoder 9, and displays the current value of the encoder 9 in real time.
[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
