Description

Technical Field

[0001] This utility model relates to the technical field of sensor disassembly and assembly tools, specifically a sensor disassembly and assembly tool. Background Technology

[0002] Currently, there are many position sensors in the casting machine area, and their installation locations are quite unique, making it impossible to remove or install them without dismantling the mechanical structure. Due to the poor installation environment, the sensors are easily damaged, directly impacting the normal production of the casting machine.

[0003] Currently, workers can only replace and repair sensors after dismantling mechanical structural components. This turns simple sensor maintenance into a large-scale project requiring the use of cranes, and coordinating with other professionals adds a significant amount of extra workload. To address this, we propose a sensor disassembly and installation tool. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sensor disassembly and installation tool, comprising: a sleeve, the front end of which has a first opening, the bottom end of which has a sensor sleeve inlet, a reinforcing ring fitted at the bottom end of the sleeve, a through square hole and a threaded hole at the top end of the sleeve, a torsion bar slidably connected inside the through square hole, a threaded rod threadedly connected inside the threaded hole, a knob fixed to the outside of the threaded rod, and an abutment block fixed to the inside of the threaded rod.

[0005] As a preferred embodiment of this utility model, the bottom end of the sleeve is provided with an external thread, and the inner side of the reinforcing ring is provided with an internal thread that meshes with the external thread.

[0006] As a preferred embodiment of the present invention, the front side of the reinforcing ring is provided with a second opening, the width of which is equal to that of the first opening.

[0007] As a preferred embodiment of this utility model, the inner side of the abutting block is provided with anti-slip texture, and the anti-slip texture abuts against the twisting strip.

[0008] As a preferred embodiment of this utility model, a fixing bolt is fixed to the top end of the sleeve.

[0009] As a preferred technical solution of this utility model, the sleeve is configured with an outer cylindrical shape and an inner hexagonal prism structure.

[0010] As a preferred embodiment of this invention, the torsion bar is a detachable, independent component.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (i) Solving the problem of working in confined spaces and reducing the complexity of operations: This utility model adapts to different working space scenarios through a switchable dual drive mode (torsion bar drive + fixed bolt drive). In particular, it is suitable for confined spaces in the casting machine area where the sensor installation position is special and the surrounding mechanical structure is blocked. The sensor can be installed and removed without removing the surrounding mechanical structure. This completely changes the traditional operation mode that requires the removal of mechanical structure, the use of cranes and the coordination of multiple professionals. It greatly simplifies the operation process and reduces the complexity of operations and the cost of manpower and materials.

[0013] (ii) Enhance structural load-bearing capacity and improve operational reliability: The sliding engagement reinforcing ring structure provides dynamic support for the sleeve opening, effectively compensating for the strength reduction caused by the opening structure. This avoids problems such as positioning failure and sensor damage caused by sleeve deformation or expansion during disassembly and assembly, ensuring structural stability and torque transmission reliability during disassembly and assembly, and extending the tool's service life.

[0014] (III) Flexible and convenient operation with strong adaptability: The twisting bar adopts a detachable independent component design, which is easy to carry and store. At the same time, the placement position can be flexibly adjusted according to the space available, and the lever principle is used to improve the ease of operation. The anti-slip texture design of the abutment block further improves the reliability of the twisting bar fixation and ensures the stability during operation. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-5 The present invention provides the following technical solution: a sensor disassembly and installation tool, comprising: a sleeve 1, a first opening 3 at the front end of the sleeve 1, a sensor sleeve inlet 4 at the bottom end of the sleeve 1, a reinforcing ring 6 at the bottom end of the sleeve 1, a through square hole 9 and a threaded hole 11 at the top end of the sleeve 1, a torsion bar 10 slidably connected inside the through square hole 9, a threaded rod 12 threadedly connected inside the threaded hole 11, a knob 13 fixed on the outside of the threaded rod 12, and an abutment block 14 fixed on the inside of the threaded rod 12.

[0025] In order to achieve a movable connection between the reinforcing ring 6 and the sleeve 1, and to ensure that the reinforcing ring 6 can move stably and be accurately positioned along the axial direction of the sleeve 1, thereby forming a reliable support for the opening of the sleeve 1, in this embodiment, as a preferred technical solution of the present invention, the bottom end of the sleeve 1 is provided with an external thread 5, and the inner side of the reinforcing ring 6 is provided with an internal thread 7 that meshes with the external thread 5.

[0026] In order to ensure that the opening structure of the reinforcing ring 6 and the sleeve 1 can be accurately aligned, and to ensure that the sleeve 1 can be quickly inserted into the end of the sensor through the opening to complete the adaptation, while meeting the structural requirement that the openings of the reinforcing ring 6 are staggered after movement to achieve support, in this embodiment, as a preferred technical solution of the present invention, a second opening 8 is provided on the front side of the reinforcing ring 6, and the width of the second opening 8 is equal to that of the first opening 3.

[0027] In order to increase the static friction between the abutment block 14 and the torsion bar 10, improve the reliability of fixing the torsion bar 10, prevent the torsion bar 10 from axially sliding or rotating during operation, and ensure the stability of power transmission and operational safety, in this embodiment, as a preferred technical solution of the present invention, the inner side of the abutment block 14 is provided with anti-slip texture, and the anti-slip texture abuts against the torsion bar 10.

[0028] In order to provide a force-bearing structure for the socket 1 to be adapted to wrench operation, so that the socket 1 can be driven to rotate by the wrench when there is sufficient working space, thereby realizing convenient installation and removal of the sensor and enriching the power drive mode of the tool, in this embodiment, as a preferred technical solution of the present invention, the top end of the socket 1 is fixed with a fixing bolt 2.

[0029] In order to make the outer surface of the sleeve 1 adaptable to the avoidance requirements of narrow working space, and at the same time, the inner side can be precisely fitted with the hexagonal bolt of the sensor to ensure that the torque can be stably transmitted to the sensor and improve the accuracy and reliability of disassembly and assembly operations, in this embodiment, as a preferred technical solution of the present invention, the sleeve 1 is configured with an outer cylindrical shape and an inner regular hexagonal prism structure.

[0030] In order to facilitate the flexible selection of whether to use the twist bar 10 according to the size of the work space and improve the flexibility and portability of the tool, in this embodiment, as a preferred technical solution of the present invention, the twist bar 10 is a detachable independent component.

[0031] Working Principle: In the initial stage of operation, the second opening 8 at the front end of the reinforcing ring 6 is aligned with the first opening 3 at the front end of the sleeve 1. This arrangement utilizes the clearance space of the opening structure, allowing the sleeve 1 to quickly engage with the sensor end through the first opening 3. This ensures that the regular hexagonal prism structure on the inner side of the sleeve 1 is precisely fitted onto the hexagonal bolts of the sensor, completing the positioning and adaptation of the tool and the sensor. Assembly and docking can be achieved without removing surrounding mechanical structural components. After the sleeve 1 and sensor are docked, the reinforcing ring 6 is rotated. Utilizing the engagement between its internal thread 7 and the external thread 5 at the bottom end of the sleeve 1, the reinforcing ring 6 is driven to move axially towards the bottom end of the sleeve 1 until it completely encloses the bottom end of the sleeve 1. During this process, the second opening 8 of the reinforcing ring 6 is misaligned with the first opening 3 of the sleeve 1, allowing the solid part of the reinforcing ring 6 to provide effective support for the opening of the sleeve 1. This compensates for the weakening of the sleeve 1's structural strength caused by the opening 3, preventing deformation or expansion of the opening due to stress during assembly and disassembly, and ensuring the stability of torque transmission.

[0032] The appropriate power drive method is selected based on the size of the on-site working space: When the working space is small and a wrench cannot be used directly, the torsion bar 10 drive mode is adopted—the detachable torsion bar 10 is inserted into the through square hole 9 at the top of the sleeve 1, and the placement position of the torsion bar 10 is adjusted according to the space allowance; if the space allows for centered operation, the torsion torque can be directly applied to the sleeve 1 through the torsion bar 10 to achieve sensor installation and removal; if the space only allows for operation on one side, the torsion bar 10 can be placed biased towards the through square hole 9, and the operating torque can be amplified by lever principle to drive the sleeve 1 to rotate from one side. When the working space is sufficient, the bolt drive mode is adopted—there is no need to install the torsion bar 10, and the torsion torque is directly applied to the sleeve 1 through the fixing bolt 2 at the top of the sleeve 1 in conjunction with the external wrench to complete the sensor installation and removal operation. When using the torsion bar 10 drive mode, after adjusting the placement of the torsion bar 10, rotate the knob 13 on the outside of the threaded rod 12. Utilizing the threaded connection between the threaded rod 12 and the threaded hole 11 at the top of the sleeve 1, the threaded rod 12 is driven to move axially inward, thereby causing the abutment block 14 on the inner side of the threaded rod 12 to move synchronously until the abutment block 14 and the torsion bar 10 are tightly fitted together. The anti-slip texture provided on the inner side of the abutment block 14 increases the static friction between it and the torsion bar 10, achieving reliable fixation of the torsion bar 10 and preventing axial slippage or circumferential rotation of the torsion bar 10 during disassembly and assembly, thus ensuring the effectiveness of power transmission and operational safety.
