Description

Technical Field

[0001] This utility model belongs to the field of rotary encoder testing technology, and in particular relates to an external encoder testing device. Background Technology

[0002] A rotary encoder is a precision sensing device that converts rotary motion into electrical signals. By detecting the angle, position, or rotational speed of a rotating shaft and outputting signals such as pulses and digital codes, it provides accurate feedback to the control system and is widely used in industrial automation, intelligent manufacturing, precision equipment and other fields.

[0003] In the production process of rotary encoders, the rotary encoder needs to be installed on a rotary motor to test its performance parameters. In the existing testing methods, a special motor needs to be replaced for each rotary encoder of a different size. In most cases, a custom motor is required to carry out the testing process. The motor manufacturing cycle is long, which affects the testing efficiency and is costly. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an external encoder testing device that can adapt to rotary encoders of different sizes by replacing the encoder fixing plate and the code disk fixing plate.

[0005] To achieve the above objectives, this utility model employs the following technical solution: an external encoder testing device, comprising a base, a rotating mechanism and an adjusting mechanism on the top of the base, the rotating mechanism comprising a power component and a rotating disk, the power component being used to drive the rotating disk to rotate, the power component being fixedly connected to the base, a code disk fixing plate being detachably connected to the top of the rotating disk, a test code disk being fixedly connected to the top of the code disk fixing plate, a test encoder being disposed above the test code disk, and the adjusting mechanism being used to adjust the position of the test encoder.

[0006] Optionally, the adjustment mechanism is detachably connected to an encoder mounting plate, which is connected to the test encoder.

[0007] Optionally, the top of the code disk fixing plate is provided with a groove, and a positioning block is provided in the groove. The positioning block is used to assist in positioning and testing the encoder.

[0008] Optionally, a limiting rod is provided in the groove, and a limiting groove is provided at the bottom of the positioning block to cooperate with the limiting rod. The limiting rod and the limiting groove are used to restrict the rotation of the positioning block.

[0009] Optionally, the groove is circular in shape, and the positioning block is a cylinder with a flat notch on one side.

[0010] Optionally, the test code disk has a ring-shaped structure, and the central axis of the ring-shaped structure coincides with the central axis of the groove.

[0011] Optionally, the power component is a linear drive motor.

[0012] Optionally, the adjustment mechanism includes a support, and a Y-axis adjustment component and a Z-axis adjustment component are sequentially arranged on the top of the support. Both the Y-axis adjustment component and the Z-axis adjustment component include knobs.

[0013] Optionally, the support is inverted U-shaped.

[0014] Optionally, a first heat insulation plate is provided between the rotating mechanism and the adjusting mechanism, and a second heat insulation plate is provided between the support and the base.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: 1. By making the code disk fixing plate and the rotating disk detachably connected, and the encoder fixing plate and the adjustment mechanism detachably connected, the corresponding code disk fixing plate and encoder fixing plate can be quickly replaced for encoder performance testing according to different sizes of rotary encoders, which improves testing efficiency, reduces processing costs, and shortens the testing cycle.

[0016] 2. By setting the Y-axis adjustment component and the Z-axis adjustment component, the position of the test encoder at the end of the encoder fixing plate is adjusted.

[0022] Example 1 Reference Figures 1-4 This embodiment provides an external encoder testing device, specifically including a base 1. A rotating mechanism 2 and an adjusting mechanism 3 are provided on the top of the base 1. The rotating mechanism 2 includes a power component 201 and a rotating disk 202. The power component 201 is used to drive the rotating disk 202 to rotate. The power component 201 is fixedly connected to the base 1. A code disk fixing plate 4 is detachably connected to the top of the rotating disk 202. A test code disk 5 is fixedly connected to the top of the code disk fixing plate 4. A test encoder 6 is provided above the test code disk 5. The adjusting mechanism 3 is used to adjust the position of the test encoder 6.

[0023] The power assembly 201 uses a linear drive motor to provide power, driving the rotating disk 202 to rotate. The code disk fixing plate 4 has multiple connecting holes axially and is detachably connected to the rotating disk 202 by multiple bolts. The test code disk 5 is fixed to the code disk fixing plate 4 by adhesive bonding. The test encoder 6 is located on the side above the test code disk 5 and is used to collect the rotation parameters of the test code disk 5.

[0024] Example 2 This embodiment provides an external encoder testing device, which differs from the first embodiment in that the adjustment mechanism 3 is detachably connected to an encoder fixing plate 7, and the encoder fixing plate 7 is connected to the test encoder 6.

[0025] The end of the encoder mounting plate 7 near the code disk mounting plate 4 is stepped to facilitate the placement of the test encoder 6. The test encoder 6 is also fixed to the encoder mounting plate 7 by means of screw connection.

[0026] The top of the code disk fixing plate 4 has a groove 401, and a positioning block 8 is set inside the groove 401. The positioning block 8 is used to assist in positioning and testing the encoder 6. A limit rod is set inside the groove 401, and a limit groove is set at the bottom of the positioning block 8 to cooperate with the limit rod. The limit rod and the limit groove are used to limit the rotation of the positioning block 8. The groove 401 is circular in shape, and the positioning block 8 is a cylinder with a flat notch on one side.

[0027] The test encoder 5 has a ring-shaped structure, and the central axis of the ring-shaped structure coincides with the central axis of the groove 401. The power unit 201 is a linear drive motor.

[0028] The limiting rod is a rectangular block, and the limiting groove is a rectangular groove. When the positioning block 8 is placed in the groove 401, it will not rotate. The flat notch of the positioning block 8 is located on the side closer to the test encoder 6, and the plane of the flat notch coincides with the plane of the corresponding side of the test encoder 6. The positioning block 8 is used for temporary auxiliary positioning. When the test encoder 6 is adjusted to the appropriate position, the positioning block 8 needs to be removed before proceeding with subsequent testing procedures.

[0029] The adjustment mechanism 3 includes a support 301. A Y-axis adjustment assembly 302 and a Z-axis adjustment assembly 303 are sequentially arranged on the top of the support 301. Both the Y-axis adjustment assembly 302 and the Z-axis adjustment assembly 303 include knobs. The support 301 is inverted U-shaped. A first heat insulation plate 9 is provided between the rotation mechanism 2 and the adjustment mechanism 3, and a second heat insulation plate 10 is provided between the support 301 and the base 1.

[0030] A side plate is fixedly connected to the top side of the Z-axis adjustment assembly 303. The side plate is fixed to the encoder mounting plate 7 by screws, allowing for quick assembly and disassembly. When installing the adjustment mechanism 3 with the base 1, ensure that the Y-axis adjustment assembly 302 and the Z-axis adjustment assembly 303 are centered in the X-axis direction. An X-axis adjustment assembly can also be added to the adjustment mechanism 3 to further improve the positioning accuracy of the test encoder 6.

[0031] During use, select the corresponding encoder mounting plate 7 according to the size of the test encoder 6. Different encoder mounting plates 7 have different stepped port sizes, corresponding to the size of the test encoder 6, for stable installation. Use bolts to connect the code disk mounting plate 4 and the rotating disk 202, and use adhesive to attach the test code disk 5 to the top of the code disk mounting plate 4. Connect the encoder mounting plate 7 to the side plate on the adjustment mechanism 3, place the positioning block 8 in the groove 401, rotate the knobs on the Y-axis adjustment assembly 302 and the Z-axis adjustment assembly 303 to adjust the test encoder 6 to the appropriate position, and finally remove the positioning block 8 and start the motor to perform the testing process.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
