Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a stepper shaft throttle motor. Background Technology

[0002] A stepper motor is an open-loop control element that converts electrical pulse signals into angular or linear displacement. Under non-overload conditions, the motor's speed and stopping position depend only on the frequency and number of pulse signals, and are not affected by load changes. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in a set direction, called the "step angle". Its rotation is done step by step at fixed angles. The angular displacement can be controlled by controlling the number of pulses, thereby achieving accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, thereby achieving speed regulation.

[0003] Referring to Chinese Patent No. CN210640804U (Published on May 29, 2020), this stepper shaft throttle motor with reduced operating vibration is simple to install and securely fixed. When the throttle motor vibrates during operation, the air in the air chamber on the motor body reduces the vibration. Simultaneously, the vibration is transmitted to the first spring through the mounting plate, and the elasticity of the first spring further reduces the vibration, making the throttle motor operate more smoothly and reducing operating vibration. The vibration generated by the throttle motor is also transmitted to the connecting rod, causing the connecting rod to move up and down. The fan blades mounted on the partition rotate under the drive of the connecting rod as it moves up and down. Air inside the housing exchanges with outside air through the through holes and vents. The vibration is used to dissipate heat during throttle motor operation, preventing overheating and reducing the throttle motor's service life. A filter screen is installed to prevent debris from entering the housing and damaging the motor.

[0004] However, the following problems exist when implementing the above technical solution: the device connects the pressure plate 7 to the crossbar, then installs the first fixing ring on the crossbar, pushes the first fixing ring, and the first fixing ring drives the pressure plate to move together, placing the pressure plate on the upper part of the motor body and limiting the upper part of the motor body. At this time, the fixing plate is attached to the outer surface of the motor body. A series of disassembly and assembly of components are required to limit and fix the motor body. The operation is too cumbersome, resulting in too long a time required for fixing and disassembly. It is not convenient to quickly disassemble and assemble the motor body. In addition, too many components are required for fixing, and many components are not set in the fixing plate, which makes it risky to lose them. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a stepper shaft throttle motor, which solves the problem that the fixing operation is too cumbersome, resulting in excessive time required for fixing and disassembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stepper shaft throttle motor, comprising a motor body and a mounting housing mounted on one side of the motor body. A cavity is formed on one side of the mounting housing, and a connecting sleeve is fixedly connected within the cavity. A limiting structure is provided within the connecting sleeve. The bottom of the connecting sleeve extends out of the mounting housing, and a rotating sleeve is rotatably connected to the extended end. A connecting assembly is provided within the rotating sleeve. The connecting assembly includes a rotating rod, one end of which extends through the connecting sleeve and out of the mounting housing. The rod is rotatably connected to the mounting housing. The other end of the rotating rod extends through the connecting sleeve and into the rotating sleeve, and is fixedly connected to the rotating sleeve. Several arc grooves are opened inside the rotating sleeve, and a sliding rod is slidably connected in the arc grooves. An adaptation groove is opened on the bottom outer wall surface of the connecting sleeve, and a connecting block is slidably connected in the adaptation groove. An extension block is fixedly connected to one end of the connecting block. One end of the sliding rod extends out of the arc groove and contacts the outer wall surface of the connecting block. One end of the extension block extends out of the rotating sleeve, and a rubber friction block is fixedly connected to the outer wall surface of the extended part.

[0007] Preferably, the limiting structure includes a limiting gear, which is sleeved on the outer wall surface of the rotating rod and fixedly connected to the rotating rod.

[0012] Beneficial effects

[0013] This invention provides a stepper shaft type throttle motor. Compared with the prior art, it has the following advantages:

[0014] Beneficial effects:

[0015] (1) The stepper shaft throttle motor, by setting a connecting component inside the mounting housing, makes it possible to install the throttle motor simply by inserting the connecting cylinder into the positioning hole or threaded opening of the part to be installed, and by contacting the inner and outer walls of the hole through the rubber friction block, thereby fixing the mounting housing to the outer wall surface of the part to be installed, making installation and disassembly more convenient. Moreover, the connecting component is set inside the mounting housing, avoiding the situation of losing parts due to too many parts.

[0016] (2) The stepper shaft throttle motor has a limiting structure in the connecting component, which limits the connecting component when the rubber friction block is in contact, so that the rubber friction block will not move after it is in contact with the outer wall of the positioning hole, making the fixation more stable.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides two technical solutions:

[0025] Example 1: A stepper shaft throttle motor includes a motor body 1 and a mounting housing 2 installed on one side of the motor body 1. The motor body 1 is prior art. A cavity is formed on one side of the mounting housing 2, and a connecting sleeve is fixedly connected inside the cavity. A limit structure 5 is provided inside the connecting sleeve. The bottom of the connecting sleeve extends out of the mounting housing 2, and a rotating sleeve 3 is rotatably connected to the end of the extended portion. A connecting assembly 4 is provided inside the rotating sleeve 3. The connecting assembly 4 includes a rotating rod 41, one end of which extends through the connecting sleeve out of the mounting housing 2 and is rotatably connected to the mounting housing 2. The other end of the rotating rod 41 extends through the connecting sleeve into the rotating sleeve 3 and is fixedly connected to the rotating sleeve 3. A plurality of arc grooves 42 are formed inside the rotating sleeve 3, and a sliding rod 43 is slidably connected inside the arc grooves 42. A matching groove is formed on the outer surface of the bottom of the connecting sleeve, and a matching groove is formed inside the matching groove. A sliding connection is provided with a connecting block 44, one end of which is fixedly connected to an extension block 45. One end of a sliding rod 43 extends out of an arc groove 42 and contacts the outer wall surface of the connecting block 44. One end of the extension block 45 extends out of a rotating sleeve 3, and a rubber friction block 46 is fixedly connected to the outer wall surface of the extended portion. The rubber friction block 46 is existing technology. By rotating the rotating rod 41, the rotating rod 41 drives the rotating sleeve 3 to rotate. The rotation of the rotating sleeve 3 causes the sliding rod 43, which is slidably connected to it, to move within the arc groove 42. The movement of the sliding rod 43 causes the connecting block 44, which is in contact with it, to move. This causes the connecting block 44 to push the extension block 45 along the matching sliding groove. The movement of the extension block 45 causes the rubber friction block 46, which is fixedly connected to it, to move, thereby causing the rubber friction block 46 to contact the outer wall of the positioning hole. This connecting component 4 can be replaced according to actual usage requirements.

[0026] In this embodiment, the limiting structure 5 includes a limiting gear 51, which is sleeved on the outer wall surface of the rotating rod 41 and fixedly connected to it. The limiting gear 51 is rotatably connected to the inner wall of the connecting sleeve, and an installation block 52 is fixedly connected to the inner wall surface of the connecting sleeve. A pulling block 53 is provided on one side of the installation block 52, and the pulling block 53 is fixedly connected to the inner wall surface of the connecting sleeve. A limiting tooth 54 is rotatably connected to the outer wall surface of the installation block 52, and the limiting tooth 54 meshes with the limiting gear 51. A pulling rod 55 is rotatably connected to the outer wall surface of one side of the limiting tooth 54. The pulling rod 55 extends through the connecting sleeve and out of the mounting shell 2, and the mounting shell 2 is slidably connected. A pulling spring 56 is fixedly connected to the outer wall surface of the limiting tooth 54, and the pulling rod 55 extends through the connecting sleeve and out of the mounting shell 2. A pulling spring 56 is fixedly connected to the outer wall surface of the limiting tooth 54. One end of the moving spring 56 is fixedly connected to the outer surface of the pulling block 53. The pulling spring 56 is used to pull the limiting tooth 54, so that the limiting tooth 54 contacts the limiting gear 51 and thus limits the limiting gear 51. It can be replaced according to actual use needs. When rotating the rotating rod 41, first pull the pulling rod 55 to one side, so that the pulling rod 55 drives the limiting tooth 54 to disengage from the limiting gear 51, so that it is no longer engaged with the limiting gear 51. At this time, the rotating rod 41 can be rotated. When it is necessary to limit the rotating rod 41, simply release the pulling rod 55, so that the limiting tooth 54 contacts the outer wall of the limiting gear 51 under the action of the pulling spring 56, thus limiting the limiting gear 51 and making the rotating rod 41 stop rotating.

[0027] Example 2: A stepper shaft throttle motor, the limiting structure 5 includes a limiting gear 51, which is sleeved on the outer wall surface of the rotating rod 41 and fixedly connected to the rotating rod 41. The limiting gear 51 is rotatably connected to the inner wall of the connecting sleeve, and a mounting block 52 is fixedly connected to the inner wall surface of the connecting sleeve. A pulling block 53 is provided on one side of the mounting block 52, and the pulling block 53 is fixedly connected to the inner wall surface of the connecting sleeve. A limiting tooth 54 is rotatably connected to the outer wall surface of the mounting block 52, and the limiting tooth 54 meshes with the limiting gear 51. A pulling rod 55 is rotatably connected to the outer wall surface of one side of the limiting tooth 54. The pulling rod 55 extends through the connecting sleeve and out of the mounting housing 2, and the mounting housing 2 is slidably connected. A pulling spring is fixedly connected to the outer wall surface of the limiting tooth 54. 56, and one end of the pull spring 56 is fixedly connected to the outer surface of the pull block 53. The pull spring 56 is used to pull the limiting tooth 54, so that the limiting tooth 54 contacts the limiting gear 51 and thus limits the limiting gear 51. It can be replaced according to actual use needs. When rotating the rotating rod 41, first pull the pull rod 55 to one side, so that the pull rod 55 drives the limiting tooth 54 to disengage from the limiting gear 51, so that it is no longer engaged with the limiting gear 51. At this time, the rotating rod 41 can be rotated. When it is necessary to limit the rotating rod 41, simply release the pull rod 55, so that the limiting tooth 54 contacts the outer wall of the limiting gear 51 under the action of the pull spring 56, thus limiting the limiting gear 51 and making the rotating rod 41 stop rotating.

[0028] The circuits and electronic components involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art and need not be elaborated upon. The scope of protection of this utility model does not involve any improvement to the internal structure and method. It should be noted that the standard parts used in this utility model can all be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art, which will not be described in detail by the inventor here.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] During operation, the rotating sleeve 3 is first inserted into the positioning hole or threaded hole. Then, the rotating rod 41 is rotated, causing the rotating sleeve 3 to rotate. The rotation of the rotating sleeve 3 causes the sliding rod 43, which is slidably connected to it, to move within the arc groove 42. The movement of the sliding rod 43 causes the connecting block 44, which is in contact with it, to move. This causes the connecting block 44 to push the extension block 45 along the matching groove. The movement of the extension block 45 causes the rubber friction block 46, which is fixedly connected to it, to move. This causes the rubber friction block 46 to contact the outer wall of the positioning hole. At this time, the pulling rod 55 is released, causing the limiting tooth 54 to contact the outer wall of the limiting gear 51 under the action of the pulling spring 56. This limits the limiting gear 51, preventing the rotating rod 41 from rotating. This is the working principle of a stepper shaft throttle motor.
