[0024] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0025] The following is for reference. Figures 1-3 This application describes a magnetic ruler assembly / disassembly tool according to an embodiment of the present application.

[0026] Please see Figure 1 and Figure 2 This application provides a magnetic ruler assembly / disassembly tool 100, which includes a sleeve 110 and a force-applying rod 120. The first end 111 of the sleeve 110 has an inner lining groove 112, the shape of which is adapted to match the magnetic ruler. The sleeve 110 has a slot 113 extending axially from its first end 111, the slot 113 connecting the inner wall of the inner lining groove 112 and the outer wall of the sleeve 110. The second end 114 of the sleeve 110 has a connecting portion. The force-applying rod 120 is mounted on the connecting portion and is perpendicular to the sleeve 110.

[0027] The sleeve 110 serves as the main structure of the tool. It can be cylindrical, or designed as a prism or other suitable shape depending on the actual usage requirements. Its primary function is to support and position the magnetic scale. The sleeve 110 has two ends: a first end 111 and a second end 114. The first end 111 engages with the magnetic scale, and the second end 114 is used to mount the force-applying rod 120, enabling effective force transmission to the magnetic scale.

[0028] The inner lining groove 112 is formed at the first end 111 of the sleeve 110. Its shape matches the magnetic ruler. For example, when the magnetic ruler is square, the inner lining groove 112 is set as a square groove. This shape design can ensure that the inner lining groove 112 and the magnetic ruler form a good snap-fit ​​fit, ensuring that the magnetic ruler will not shake or shift relative to the sleeve 110 during the disassembly and assembly process, thereby improving the stability and accuracy of the operation.

[0029] The slot 113 extends axially from the first end 111 of the sleeve 110 and connects the inner wall of the inner lining groove 112 and the outer wall of the sleeve 110. The slot 113 is designed to accommodate the cable on the magnetic scale, preventing it from being squeezed or damaged during assembly and disassembly. The width of the slot 113 can be adjusted according to the diameter of the cable. The slot 113 is connected to the inner lining groove 112, allowing the cable on the magnetic scale to extend from inside the inner lining groove 112 through the slot 113 to the outside of the sleeve 110, ensuring that the inner lining groove 112 and the magnetic scale can fully cooperate without interference from the cable.

[0030] A connecting part is located at the second end 114 of the sleeve 110 for mounting the force-applying rod 120. The connecting part can be a protrusion welded to the second end 114 of the sleeve 110, with a through hole 115 on the protrusion through which the force-applying rod 120 passes to connect with the sleeve 110; alternatively, it can be a sleeve integrally formed with the sleeve 110, into which the force-applying rod 120 is inserted and fixed. The structural design of the connecting part must ensure a firm connection between the force-applying rod 120 and the sleeve 110, preventing loosening during the application of force.

[0031] The lever 120 is installed at the connecting part and is perpendicular to the sleeve 110. The lever 120 can be made of metal and its length can be set according to actual needs, such as 20cm, 30cm, 50cm, etc. The perpendicular setting of the lever 120 to the sleeve 110 utilizes the lever principle, allowing the operator to generate a large torque on the sleeve 110 with a small force, thereby making it easier to complete the installation and removal of the magnetic ruler.

[0032] In actual operation, when installing the magnetic scale, align the end of the magnetic scale with the inner groove 112 of the first end 111 of the sleeve 110, so that the magnetic scale is embedded in the inner groove 112. At the same time, lead the cable on the magnetic scale out through the slot 113 to the outside of the sleeve 110. At this time, the operator holds the lever 120. Since the lever 120 is perpendicular to the sleeve 110, rotating the lever 120 can drive the sleeve 110 to rotate together, thereby installing the magnetic scale onto the corresponding equipment. When disassembling the magnetic scale, similarly, embed the end of the magnetic scale into the inner groove 112, lead the cable out through the slot 113, rotate the lever 120, and use the torque generated by the lever 120 to remove the magnetic scale from the equipment.

[0033] The magnetic scale assembly / disassembly tool 100 provided in this application embodiment has a simple structure. The magnetic scale is matched and engaged through the inner groove 112 of the sleeve 110, and the cable is accommodated by the slot 113, ensuring a stable fit between the magnetic scale and the tool and preventing interference from the cable during operation. The force-adjusting rod 120 is perpendicular to the sleeve 110, utilizing the lever principle to greatly reduce the force required for operation, allowing operators to easily complete assembly / disassembly. This significantly shortens the magnetic scale replacement time, improves work efficiency, and reduces the possibility of damage to the magnetic scale or inaccurate installation due to improper operation, ensuring the subsequent operating efficiency and accuracy of the equipment.

[0034] Please see Figure 1 and Figure 3 According to some embodiments of this application, the inner lining groove 112 can be a hexagonal inner lining structure, with the distance between the two parallel sides of the inner lining groove 112 being 45mm-50mm and the diagonal distance being 50mm-58mm.

[0035] The inner groove 112 features a hexagonal design, allowing it to fit snugly with the hexagonal cross-section of the magnetic ruler. This hexagonal liner provides a more stable locking mechanism, effectively preventing slippage or rotation of the magnetic ruler during assembly and disassembly. This design is particularly suitable for installation scenarios requiring precise alignment. The six sides of the hexagon fit tightly against the six faces of the magnetic ruler, dispersing stress through surface contact and preventing excessive localized stress that could damage the ruler's surface.

[0036] The parallel side spacing (distance between opposite sides) is 45mm-50mm. Specifically, it can be 45mm, 46mm, 48mm, 50mm or other values ​​between 40mm and 50mm. This size range is compatible with the mainstream industrial magnetic ruler specifications on the market, ensuring that the inner groove 112 and the magnetic ruler have sufficient contact area to transmit torque, while maintaining an appropriate assembly gap to facilitate the insertion and removal of the magnetic ruler.

[0037] The diagonal spacing (diagonal distance) is 50mm-58mm. This parameter determines the diameter of the circumscribed circle of the hexagonal inner groove 112, and together with the parallel side spacing, constitutes the complete geometric parameters of the hexagon. The reasonable range of diagonal spacing design allows the inner groove 112 to accommodate the rounded or chamfered structure of the magnetic ruler, while ensuring reliable contact between the hexagonal vertices and the surface of the magnetic ruler.

[0038] When the magnetic ruler is inserted into the hexagonal inner groove 112, all six sides simultaneously contact the surface of the magnetic ruler, forming a multi-faceted constraint. When a torque is applied, the force is evenly transmitted to the magnetic ruler through the six faces of the inner groove 112, avoiding stress concentration caused by single-point force application. Due to the symmetry of the hexagonal structure, regardless of whether the force-applying rod 120 is rotated clockwise or counterclockwise, the force distribution between the inner groove 112 and the magnetic ruler remains uniform, ensuring efficient torque transmission.

[0039] According to some embodiments of this application, the inner wall of the inner lining groove 112 may be provided with a plurality of anti-slip protrusions, and the plurality of anti-slip protrusions may be evenly distributed along the circumferential direction of the inner wall of the inner lining groove 112.

[0040] Anti-slip protrusions are provided on the inner wall of the inner lining groove 112 to increase the friction between the inner lining groove 112 and the surface of the magnetic ruler, preventing relative sliding between the magnetic ruler and the inner lining groove 112 during assembly and disassembly. The anti-slip protrusions can take various structural forms, such as:

[0041] Hemispherical protrusions: The diameter can be 1mm-3mm and the height can be 0.3mm-1mm. This shape can provide sufficient friction while avoiding scratches on the surface of the magnetic ruler.

[0042] Strip-shaped protrusions: 1mm-2mm wide and 0.2mm-0.5mm high, extending axially or circumferentially along the inner lining groove 112, forming a grid-like or parallel pattern;

[0043] Serrated protrusions: tooth height is 0.2mm-0.5mm, tooth pitch is 2mm-5mm, suitable for scenarios requiring greater friction.

[0044] Multiple anti-slip protrusions are evenly arranged along the circumference of the inner wall of the inner lining groove 112, for example, 6, 8, or 12 protrusions, ensuring that the magnetic ruler receives balanced friction in all directions. This distribution allows torque to be evenly transmitted to the surface of the magnetic ruler, avoiding excessive local force that could cause deformation or damage to the magnetic ruler. When the magnetic ruler is inserted into the inner lining groove 112, the anti-slip protrusions form multi-point contact with the surface of the magnetic ruler, increasing friction by increasing the contact area and surface roughness. When torque is applied, the anti-slip protrusions effectively resist the relative sliding tendency between the magnetic ruler and the inner lining groove 112, ensuring that the torque transmitted by the force-applying rod 120 can be fully applied to the magnetic ruler, achieving efficient assembly and disassembly operations.

[0045] Please see Figures 1 to 3 According to some embodiments of this application, the slot 113 can be a rectangular slot 113 with a length of 100mm-150mm and a width of 8mm-12mm.

[0046] The slot 113 adopts a rectangular structure design. Compared with other shapes (such as semi-circular or trapezoidal), the rectangular slot 113 has a larger contact area between the edge and the cable, which can effectively disperse the compressive stress on the cable and reduce the risk of the cable being scratched or damaged. At the same time, the rectangular straight-edge structure is easier to process and manufacture, reducing production costs.

[0047] The length (axial extension distance) of the slot 113 can be 100mm-150mm, specifically 100mm, 110mm, 130mm, 140mm, etc. This length range can meet the lead-out requirements of different types of magnetic scale cables. For longer magnetic scales, the longer slot 113 allows the cable sufficient bending space outside the sleeve 110, avoiding excessive bending of the cable at the edge of the slot 113, which could affect signal transmission or damage the internal structure of the cable.

[0048] The width of the slot 113 can be 8mm-12mm, specifically 8mm, 10mm, 12mm, etc. This width range is suitable for common magnetic ruler cable diameters (usually 5mm-10mm). An appropriate width ensures that the cable can pass through the slot 113 smoothly, while preventing the slot 113 from being too wide, which would reduce the structural strength of the sleeve 110 or cause the cable to wobble excessively within the slot 113.

[0049] According to some embodiments of this application, the inner edge of the rectangular slot 113 may be provided with an elastic protective layer, the thickness of which may be 1mm-2mm, and the outer surface of the elastic protective layer may be provided with an arc-shaped transition surface.

[0050] An elastic protective layer is installed on the inner edge of the rectangular slot 113 and is made of elastic materials such as rubber and silicone. The main function of this protective layer is to buffer the contact stress between the cable and the edge of the slot 113, preventing the cable from being scratched or deformed by the rigid edge. The thickness of the elastic protective layer is 1mm-2mm. This thickness range provides sufficient buffering performance without significantly reducing the effective width of the slot 113 due to excessive thickness, thus affecting cable passage.

[0051] The curved transition surface is located on the outer surface of the elastic protective layer. The design of the curved transition surface allows the cable to smoothly transition when passing through the slot 113, avoiding stress concentration caused by right angles or sharp edges. This design is especially suitable for cables that require frequent bending, reducing the risk of breakage of the internal conductors of the cable.

[0052] When the magnetic scale cable passes through slot 113, the elastic protective layer first contacts the cable, absorbing the impact and compression forces on the cable through its own elastic deformation. The arc-shaped transition surface guides the cable to move along a smooth path, reducing the frictional resistance between the cable and the protective layer. During assembly and disassembly, even if the cable slides or collides with the edge of slot 113, the elastic protective layer can effectively disperse stress and protect the cable from damage.

[0053] Please see Figures 1 to 3 According to some embodiments of this application, the connecting part may include a through hole 115 extending radially through the sleeve 110, and the force-adding rod 120 passing through the through hole 115.

[0054] A radially penetrating through hole 115 is formed at the second end 114 of the sleeve 110, completely penetrating the side wall of the sleeve 110 along its radial direction. The diameter of the through hole 115 is adapted to the outer diameter of the extension rod 120, typically 0.1mm-0.3mm larger than the outer diameter of the extension rod 120, to ensure that the extension rod 120 can be smoothly inserted into the through hole 115 and rotate freely. For example, when the outer diameter of the extension rod 120 is 10mm, the diameter of the through hole 115 can be designed to be 10.2mm.

[0055] When the operator applies torque to the lever 120, the force is transmitted to the sleeve 110 through the contact interface between the lever 120 and the through hole 115. Since the through hole 115 is radially arranged along the sleeve 110 and the lever 120 is perpendicular to the sleeve 110, according to the lever principle, the longer the lever 120, the smaller the force required by the operator. During assembly and disassembly, the lever 120 can rotate freely around the axis of the through hole 115, allowing the operator to adjust the direction of force application as needed.

[0056] Please see Figures 1 to 3 According to some embodiments of this application, both ends of the extension rod 120 may be provided with detachable anti-slip grips 130, and the outer surface of the anti-slip grips 130 is provided with anti-slip texture.

[0057] The anti-slip grip 130 can be made of anti-slip materials such as rubber, silicone, or soft plastic, and can be fixed to both ends of the extension bar 120 by means of snap-fit ​​connection or interference fit. The detachable design facilitates grip replacement and maintenance; for example, when the grip surface wears down and its anti-slip performance decreases, the grip can be replaced individually without replacing the entire extension bar 120. When the operator grips the extension bar 120, the anti-slip grip 130 further increases the contact friction with the palm through the material's coefficient of friction and surface texture. The detachable design allows for the replacement of grips of different materials or textures according to different usage scenarios (such as wet environments or operations requiring greater grip strength). During torque application, the anti-slip grip 130 effectively prevents relative slippage between the palm and the extension bar 120, ensuring that the operator can stably and accurately transmit force.

[0058] According to some embodiments of this application, the anti-slip grip 130 can be threadedly connected to the extension bar 120.

[0059] For example, the inner wall of the anti-slip grip 130 may be provided with internal threads, and both ends of the extension rod 120 may be provided with corresponding external threads, achieving a detachable connection through thread engagement. The thread specification can adopt metric or imperial standards, specifically determined according to the diameter of the extension rod 120 and the design load. The thread profile can be either triangular or trapezoidal. Triangular threads have better self-locking performance and are suitable for static connections; trapezoidal threads have higher transmission efficiency and are suitable for scenarios requiring frequent disassembly.

[0060] In some examples, the extension rod 120 may have threaded holes at both ends along the axial direction, and the end of the anti-slip grip 130 may have a threaded connector adapted to the threaded holes. The length of the threaded connector is less than the depth of the threaded hole. After the threaded connector mates with the threaded hole, the main body of the anti-slip grip 130 is connected to the end of the extension rod 120, thereby extending the effective operating length of the extension rod 120. When the operator needs a larger disassembly torque, the anti-slip grip 130 is screwed into the threaded hole at the end of the extension rod 120 through the threaded connector, so that the extended part of the grip forms an extension arm. When rotating the extension rod 120, the extended lever arm allows the operator to generate sufficient torque with less force, easily completing the disassembly or installation of the magnetic ruler. After operation, the anti-slip grip 130 can be unscrewed for carrying or replacement with different types of grips.

[0061] According to some embodiments of this application, the second end 114 of the sleeve 110 is cylindrical, the connecting part includes two through holes 115 penetrating the two opposite side walls of the sleeve 110, the middle part of the force rod 120 is provided with a bayonet, a detachably connected locking pin 121 is installed in the bayonet, at least a portion of the locking pin 121 extends out of the bayonet and is located inside the sleeve 110.

[0062] The second end 114 of the sleeve 110 can be an open cylindrical structure, with a through hole 115 on each of its two opposite side walls. The axes of the two through holes 115 coincide and are perpendicular to the axial direction of the sleeve 110. The double through holes 115 can more stably support the force-adding rod 120 and reduce the bending deformation of the force-adding rod 120 under stress.

[0063] The bayonet is located in the middle of the extension rod 120 and is a radially penetrating groove along the extension rod 120. The width of the groove is adapted to the diameter of the locking pin 121. The locking pin 121 can be a cylindrical pin or a tapered pin, and the material can be metal (such as 45 steel or stainless steel) or hard plastic. The diameter of the locking pin 121 is slightly smaller than the width of the bayonet, and the length is greater than the diameter of the extension rod 120, ensuring that after installation, at least one end of the locking pin 121 extends out of the bayonet and is located within the cylindrical structure of the sleeve 110.

[0064] The connection between the card pin 121 and the card slot can be any of the following methods:

[0065] First, after the locking pin 121 is inserted into the bayonet, a cotter pin is inserted into the radial hole at the end of the locking pin 121 to prevent the locking pin 121 from moving axially.

[0066] Secondly, internal threads are machined on the inner wall of the bayonet, and external threads are machined on the outer surface of the locking pin 121. Fastening is achieved by rotating the locking pin 121.

[0067] Third, an annular groove is made on the inner wall of the bayonet, and an elastic retaining ring is provided on the surface of the locking pin 121. After the locking pin 121 is inserted, the retaining ring cooperates with the annular groove to achieve locking.

[0068] During installation, first pass the extension rod 120 through the two through holes 115 of the sleeve 110, aligning the locking tab in the middle of the extension rod 120 with the cylindrical inner cavity of the sleeve 110; then insert the locking pin 121 into the locking tab, ensuring that at least one end of the locking pin 121 extends outside the locking tab and is located inside the sleeve 110. When the operator applies torque to the extension rod 120, the extension rod 120 will not move axially due to the restraining effect of the locking pin 121, ensuring operational stability. During disassembly, simply remove the locking pin 121 to pull the extension rod 120 out of the sleeve 110, facilitating tool storage and maintenance.

[0069] Please see Figures 1 to 3 According to some embodiments of this application, the outer peripheral wall of the sleeve 110 is circular, the length of the sleeve 110 is 250mm-270mm, and the outer diameter of the sleeve 110 is 60mm-70mm.

[0070] The outer peripheral wall of the sleeve 110 is designed in a circular shape. This shape not only facilitates manufacturing but also provides a more comfortable grip when the operator needs assistance in holding the sleeve 110, avoiding pressure or scratches to the operator's hands caused by sharp edges. Simultaneously, the circular structure results in a more uniform stress distribution under load, contributing to improved overall structural strength and extended service life of the sleeve 110. During the assembly and disassembly of the magnetic scale, the circular outer peripheral wall of the sleeve 110 allows for smoother integration with the surrounding space, reducing interference with other components of the equipment that might occur due to the irregular shape of the outer peripheral wall.

[0071] The length of the sleeve 110 (the distance from the first end 111 to the second end 114) can be 250mm-270mm, specifically 250mm, 260mm, 270mm, etc. This length range can accommodate the installation and disassembly requirements of most common magnetic rulers. For example, when the magnetic ruler is installed at a deep depth, a length of 270mm ensures that the sleeve 110 has enough space to engage with the magnetic ruler, ensuring operational stability; while for magnetic rulers with a shallow installation depth, a length of 250mm can also meet basic installation and disassembly operations without causing inconvenience due to excessive length.

[0072] The outer diameter of the sleeve 110 can be 60mm-70mm, specifically 60mm, 65mm, 70mm, etc. This outer diameter range ensures that the sleeve 110 has sufficient structural strength without making it too bulky. A 60mm outer diameter saves more material and is suitable for scenarios where tool weight is a concern; a 70mm outer diameter provides stronger structural support and is suitable for disassembly and assembly operations that require the transmission of larger torques.
