Description

Technical Field

[0001] This utility model relates to the field of micro handwheel technology, and in particular to a micro handwheel that is easy to replace. Background Technology

[0002] Micro handwheels, with hand-crank operation as their core, primarily translate the operator's physical actions into precise linear displacement of the target component. This enables high-precision positioning and micro-adjustment of the equipment, effectively ensuring accurate control and reliable operation. Their core applications are concentrated in CNC machining, robotics and automation, and precision instruments—scenarios with stringent requirements for displacement control precision.

[0003] However, in the existing technology, the existing micro handwheels are mainly fixed by threaded and nut connections. This structure is prone to loosening due to vibration, fatigue and other factors during long-term use, which not only affects the stability of equipment operation, but may also cause safety hazards and adversely affect the work process. At the same time, the micro handwheels using this fixing method are complicated to operate and have low disassembly and installation efficiency during daily maintenance and replacement, which brings inconvenience to actual use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Most existing micro handwheels are fixed with threads and nuts, which are prone to loosening due to vibration and fatigue after long-term use, affecting the stability of the equipment and posing safety hazards. Moreover, maintenance and replacement operations are cumbersome and inefficient. This invention provides a micro handwheel that is easy to replace.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a micro handwheel that is easy to replace, comprising a main body mechanism, an adjustment mechanism at one end of the main body mechanism, and a disassembly and assembly mechanism at the other end of the main body mechanism. The adjustment mechanism includes a first slide rod installed on one side of the main body mechanism, a first slider fixedly connected to the outer surface of the first slide rod, a fixing block slidably connected to the outer surface of the first slider, a sliding groove on the outer surface of the fixing block, a first limiting groove on one side of the fixing block, a housing slidably penetrating the outer surface of the first slide rod, a limiting block fixedly connected to the outer surface of the first slide rod, and a second limiting groove on one side of the housing.

[0006] In a preferred embodiment, the disassembly and assembly mechanism includes a knob mounted on one side of the main body, and a second slide rod is threadedly connected to the inner wall of the knob.

[0007] In a preferred embodiment, a second slider is fixedly connected to one end of the second slide rod, and a spring is provided on the inner wall of the second slide rod.

[0008] In a preferred embodiment, the inner wall of the second slide bar is provided with a third limiting groove, and the outer surface of the second slider is engaged with the inner wall of the third limiting groove.

[0009] In a preferred embodiment, one end of the spring is fixedly connected to the inner wall of the first slide rod, and the other end of the spring is slidably connected to one side of the third limiting groove.

[0010] In a preferred embodiment, an adjustment ring is fixedly connected to the outer surface of the housing, and one side of the fixing block is engaged with one side of the housing.

[0011] In a preferred embodiment, the outer surface of the limiting block is engaged with the inner wall of the second limiting groove, and the outer surface of the fixing block is engaged with the first limiting groove.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: The first and second slide rods of this invention adopt a snap-fit ​​connection structure, which can achieve both a stable connection and flexible independent separation. By rotating the knob, the first slide rod is driven to move in a straight line using the principle of threaded transmission, thereby causing the first slider and the limiting block at the end of the first slide rod to simultaneously disengage from their respective slots. After the slot positions are switched by rotating the fixing block 26, the two slide rods can be quickly fixed and separated. The entire operation logic is clear and easy to execute, effectively improving the reliability of the connection and the flexibility of operation. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] Example 1 like Figure 1-5 As shown, this utility model provides a technical solution: a micro handwheel that is easy to replace, including a main body 1, an adjustment mechanism 2 is provided at one end of the main body 1, and a disassembly and assembly mechanism 3 is provided at the other end of the main body 1. The adjustment mechanism 2 includes a first slide rod 23 installed on one side of the main body 1, a first slider 24 is fixedly connected to the outer surface of the first slide rod 23, a fixing block 25 is slidably connected to the outer surface of the first slider 24, a sliding groove 21 is provided on the outer surface of the fixing block 25, a first limiting groove 22 is provided on one side of the fixing block 25, a housing 11 is slidably connected through the outer surface of the first slide rod 23, a limiting block 27 is fixedly connected to the outer surface of the first slide rod 23, and a second limiting groove 28 is provided on one side of the housing 11.

[0021] In this embodiment, the outer surface of the first slide rod 23 forms a through-sliding fit with the inner wall of the outer shell 11, ensuring that it can slide smoothly inside the outer shell 11. One end of the first slide rod 23 is fixedly connected to the first slider 24. The sliding groove 21 opened at one end of the fixing block 25 provides a stable sliding channel for the first slider 24. The first limiting groove 22, which is perpendicular to the sliding groove 21, can effectively limit the rotational freedom of the first slider 24. Through the cooperative cooperation of the sliding groove 21 and the first limiting groove 22, the reliable positioning of the first slider 24 is achieved. In addition, the limiting block 27 fixed at the rear end of the first slide rod 23 can be accurately engaged in the second limiting groove 28 opened on one side of the outer shell 11, forming a bidirectional limiting structure with the front first limiting groove 22, further improving the constraint effect on the first slide rod 23 and ensuring its motion stability and positioning accuracy.

[0022] Example 2 like Figure 1-5As shown, the disassembly and assembly mechanism 3 includes a knob 31 installed on one side of the main body mechanism 1. The inner wall of the knob 31 is threaded with a second slide rod 32. One end of the second slide rod 32 is fixedly connected to a second slider 33. A spring 34 is provided on the inner wall of the second slide rod 32. A third limiting groove 35 is opened on the inner wall of the second slide rod 32. The outer surface of the second slider 33 is engaged with the inner wall of the third limiting groove 35. One end of the spring 34 is fixedly connected to the inner wall of the first slide rod 23, and the other end of the spring 34 is slidably connected to one side of the third limiting groove 35. An adjusting ring 26 is fixedly connected to the outer surface of the outer shell 11. One side of the fixing block 25 is engaged with one side of the outer shell 11. The outer surface of the limiting block 27 is engaged with the inner wall of the second limiting groove 28. The outer surface of the fixing block 25 is engaged with the first limiting groove 22.

[0023] In this embodiment, one end of the knob 31 has an internal thread that precisely meshes with the external thread on the outer surface of one end of the second slide rod 32, forming a threaded transmission mechanism. When the knob 31 is rotated, the mechanical transmission through the threaded engagement drives the second slide rod 32 to move linearly along the axial direction. The other end of the second slide rod 32 is fixedly connected to the second slider 33, which is fitted into the third limiting groove 35 built into one end of the first slide rod 23. One channel provides sliding guidance for the second slider 33, while the other channel serves as a rotation limit. At the same time, the spring 34 disposed at one end of the first slide rod 23 provides an elastic preload to drive the second slider 33 to quickly engage in the groove when it rotates to the position corresponding to the third limiting groove 35, thereby achieving reliable fixation of the second slide rod 32 and the first slide rod 23. The structure is compact and has strong positioning stability.

[0024] Working principle: like Figure 1-5 As shown, when changing the handwheel, first turn the knob 31. Utilizing its precise threaded engagement with the second slide rod 32, the second slide rod 32 is driven to rotate synchronously and move linearly along the axial direction via the threaded transmission principle. The second slide rod 32, through the engagement of its end second slider 33 with the third limiting groove 35 built into the first slide rod 23, drives the first slide rod 23 to rotate synchronously. Simultaneously, under the continuous action of the threaded transmission, the first slide rod 23 is pushed to produce axial linear displacement, causing the first slider 24 at the front end of the first slide rod 23 and the limiting block 27 at the rear end to disengage from the constraints of the first limiting groove 22 and the second limiting groove 28, respectively.

[0025] Then, rotate the second slide bar 32 to drive the first slider 24 and the limit block 27 to rotate synchronously to the corresponding preset disengagement channel position. At this time, pull the second slide bar 32 outward to complete the quick disassembly of the handwheel. The entire disassembly process does not require any additional tools. The operation process is simple and smooth, greatly improving the efficiency of maintenance and replacement.

[0026] When it is necessary to separate the first slide bar 23 from the second slide bar 32, press the knob 31 inward. The axial pressure of the knob 31 drives the second slide bar 32 to move inward and compress the spring 34. After the spring 34 is compressed to the preset stroke, rotate the second slide bar 32 to align the second slider 33 with the disengagement channel. Then release the pressing force on the knob 31. Under the elastic restoring force of the spring 34 and the cooperation of the structure, the first slide bar 23 and the second slide bar 32 can be quickly separated. After separation, the adjustment ring 26 can be used for adjustment. The operation is convenient and the separation process is stable and reliable.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
