Description

Technical Field

[0001] This utility model relates to the field of encoder technology, and in particular to a code disk adhesive positioning component. Background Technology

[0002] The code disk is part of a digital encoder that measures angular displacement. It has the advantages of high resolution, high measurement accuracy and reliable operation, and is one of the most common displacement sensors for measuring the angular position of a shaft.

[0003] In the field of encoder assembly structure, the assembly of encoder and support components in the existing technology often faces problems such as positioning accuracy, ease of installation and connection stability. Traditional assembly methods are difficult to accurately define the position of the encoder, and the encoder is easily contaminated when touched by hand. In addition, the connection between the encoder and the support sleeve is not reliable, which affects the overall performance and service life of the equipment.

[0004] This technical solution proposes a structure comprising a positioning base, a code disk, and an I-shaped support sleeve. The positioning base has a groove to facilitate the concentric placement of the code disk, and the groove edge is slotted to facilitate hand contact with the edge of the code disk for easy placement and removal. The top surface of the I-shaped support sleeve is glued to the bottom surface of the code disk to achieve a stable support connection for the code disk. By utilizing the specific structural positional relationship of each component, this solution aims to solve the aforementioned assembly problem and improve the convenience, stability, and accuracy of code disk assembly. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-3 A code disk bonding and positioning component includes a positioning base 1. A groove 3 is axially formed at the top of the positioning base 1. A code disk 2 is placed inside the groove 3, and the inner diameter of the groove 3 and the outer diameter of the code disk 2 form a clearance fit. An annular grating 21 is concentrically arranged on the code disk 2. A shaft tube 4 protrudes axially upward from the center of the groove 3. An I-shaped support sleeve 5 is fitted onto the outer wall of the shaft tube 4. The I-shaped support sleeve 5 is positioned between the code disk 2 and the bottom of the groove 3, and its top surface supports the code disk 2. A slot 6 is formed on the inner wall of the groove 3. An annular overlapping portion 7 protrudes radially outward from the bottom of the positioning base 1.

[0024] By achieving a clearance fit between the inner diameter of the groove 3 and the outer diameter of the code disk 2, the code disk 2 is precisely coaxially placed within the groove 3. This facilitates quick insertion of the code disk and limits radial offset, ensuring the concentricity of the code disk 2. The shaft tube 4 positions the I-shaped support sleeve 5 to ensure its concentricity with the code disk 2. The I-shaped support sleeve 5 provides uniform support for the code disk 2, facilitating subsequent assembly with the code disk 2. When picking up or placing the code disk 2, care must be taken to avoid the annular grating 21 and surface area on the code disk 2 to prevent wear or contamination. The slot 6 provides operating space for picking up or placing the code disk 2, allowing for easy finger contact with the edge of the code disk 2. The annular stacking part 7 at the bottom of the positioning base 1 allows multiple positioning components to be stacked, saving storage and transportation space.

[0025] The bottom of the code disk 2 is in contact with the I-shaped support sleeve 5, which is an adhesive surface. The I-shaped support sleeve 5 includes an upper ring, a lower ring, and an intermediate column that are coaxially integrally formed. The intermediate column is sleeved on the outside of the shaft tube 4. The top surface of the upper ring is bonded to the adhesive surface of the code disk 2 by applying glue, and the bottom surface of the lower ring is in contact with the bottom surface of the groove 3.

[0026] The "integrated upper ring, lower ring and middle column" structure of the I-shaped support sleeve 5 enhances the rigidity of the support sleeve itself and avoids deformation under stress; the "middle column is sleeved on the outside of the shaft tube 4" further radially positions the I-shaped support sleeve 5 through the shaft tube 4, ensuring the coaxiality of the I-shaped support sleeve 5 and the code disk 2; the double contact design of "adhesive bonding between the top surface of the upper ring and the adhesive surface of the code disk 2" + "fitting between the bottom surface of the lower ring and the bottom surface of the groove 3" allows the I-shaped support sleeve 5 to be stably supported at the bottom of the groove through the lower ring and to form a firm connection with the code disk 2 through the upper ring.

[0027] At least two slots 6 are provided and are distributed circumferentially along the inner wall of the groove 3. The inner edge of the slots 6 extends to the outer peripheral wall of the code disk 2, exposing part of the edge of the code disk 2.

[0028] This ensures that the edge of the code disk 2 can be touched from multiple directions during operation, avoiding the code disk 2 from tilting due to unidirectional force application, thus facilitating the picking and putting-away operation of the code disk 2.

[0029] The annular stacking part 7 is an annular protrusion coaxial with the positioning base 1, and the outer diameter of the annular stacking part 7 and the inner diameter of the groove 3 form a clearance fit to facilitate the stacking of multiple positioning bases 1.

[0030] When multiple positioning bases 1 are stacked, the annular stacking part 7 can be precisely embedded in the groove 3 of another base. The radial limit is achieved through clearance fit, which avoids shaking after stacking and improves the convenience of batch storage and transportation. When stacked, the bottom surface of the annular stacking part 7 does not contact the upper surface of the code disk 2.

[0031] The top end face of the shaft tube 4 is lower than the top surface of the upper ring of the I-shaped support sleeve 5, and the shaft tube 4 and the positioning base 1 are integrally formed.

[0032] To prevent the shaft tube 4 from directly contacting the code disk 2, the bonding surface of the code disk 2 should only be bonded to the top surface of the I-shaped support sleeve 5.

[0033] Working principle:

[0034] The groove 3 of the positioning base 1 and the code disk 2 are initially coaxially positioned through a clearance fit; the shaft tube 4 is fitted with an I-shaped support sleeve 5 and its radial limit is set. The lower ring of the support sleeve 5 is attached to the bottom of the groove 3, and the top surface of the upper ring is glued to the bottom bonding surface of the code disk 2 to provide stable support for the code disk 2; when picking up and putting down the code disk 2, the groove 6 on the inner wall of the groove 3 contacts the edge of the code disk to avoid the grating 21; multiple positioning bases 1 can be stacked and stacked through the clearance fit between the annular stacking part 7 and the groove 3, and finally the precise positioning, stable bonding, safe picking up and putting down and convenient storage of the code disk 2 are completed.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
