During long-term use, the vibration will be transmitted to the bolts, which may cause the bolts to loosen due to reverse rotation. This will not only cause the motor to shake during operation, affecting the operating accuracy of the equipment, but may also damage the connecting parts due to the displacement of the motor, shortening the service life of the equipment. Therefore, a new type of stepper motor is proposed to solve the above problems. Utility Model Content

[0033] 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.
[0034] Reference Figure 1 - Figure 2 The present invention provides an embodiment of a novel stepper motor, comprising a body 1, which is a stepper motor housing and belongs to the prior art, and can be implemented by those skilled in the art. Since it is prior art, it will not be described in detail in this case. The top of the body 1 is provided with an anti-loosening component, which can prevent the mounting bolt 2 from reversing and falling off due to vibration caused by the operation of the body 1, thereby ensuring the stability of the installation of the body 1. The top of the body 1 is provided with a positioning component, which can adjust the position of the mounting bolt 2 to align with the threaded hole pre-drilled on the mounting device.
[0035] Reference Figure 2 - Figure 4The anti-loosening component includes a mounting block 31, which is slidably connected to the inner surface of the body 1. The mounting block 31 moves in the front-back direction and is located on the diagonal of the top view of the body 1. The inner surface of the mounting block 31 is rotatably connected to a mounting bolt 2 for fixing the body 1. A washer 32 is fixedly connected to the upper surface of the mounting bolt 2. The washer 32 is a plastic part with a certain deformation capacity, which allows the mounting bolt 2 to continue to be tightened a certain distance when tightened. A slot 33 is opened on the upper surface of the mounting bolt 2. A moving ring 34 is elastically connected to the inner wall of the top of the mounting block 31 through a compression spring 36. A locking block 35 is fixedly connected to the lower surface of the moving ring 34. The locking block 35 and the slot 33 fit together. There are four sets of washer 32, locking block 35 and slot 33, arranged in a circular array with the center of the moving ring 34 as the origin. A pressure rod 37 is fixedly connected to the lower surface of the moving ring 34. The moving ring 34 and the pressure rod 37 move synchronously.
[0036] Reference Figure 2 - Figure 4 The bottom end of the right surface of the locking block 35 is set as an arc surface. When the arc surface is squeezed, the locking block 35 will move upward, which will drive the moving ring 34 to move upward. The upward moving locking block 35 will gradually release the obstruction. The upward moving ring 34 will squeeze the compression spring 36 to generate a reaction force. The locking block 35 is inserted into the inner wall of the slot 33, which can limit the mounting bolt 2 in one direction. When the locking block 35 and the slot 33 are inserted, the mounting bolt 2 cannot rotate in the opposite direction, causing loosening. The thickness of the locking block 35 is greater than the depth of the slot 33. The moving ring 34 is slidably connected to the inner wall of the mounting block 31. The moving ring 34 moves longitudinally. The upward moving ring 34 will squeeze the compression spring 36 to generate a reaction force. The pressure rod 37 passes through and is slidably connected to the lower surface of the mounting block 31. The bottom end of the pressure rod 37 is set as a protrusion. By observing the length of the pressure rod 37 protruding from the mounting block 31, the position of the moving ring 34 and the locking block 35 can be determined.
[0037] Reference Figure 2 , Figure 5 , Figure 6 The positioning component includes a limiting block 41, which is slidably connected to the right surface of the mounting block 31. The inner wall of the right side of the body 1 is elastically connected to a sliding plate 42 via a connecting spring 43. A top block 44 is fixedly connected to the left surface of the sliding plate 42. A limiting groove 45 is provided on the inner surface of the body 1. Multiple sets of top blocks 44 and limiting grooves 45 are provided, which are distributed at equal intervals in front and behind the left surface of the sliding plate 42. The distance between them is suitable for the mounting points (i.e., threaded holes) on various conventional installation devices on the market.
[0038] Reference Figure 2 , Figure 3 , Figure 6The limiting block 41 is inserted into the inner wall of the limiting groove 45 to limit the mounting block 31. The right edge of the limiting block 41 is chamfered to facilitate the insertion of the limiting block 41 and the limiting groove 45. The sliding plate 42 is slidably connected to the inner wall of the body 1 and moves laterally. When the sliding plate 42 moves to the right, it will compress the connecting spring 43 to generate a reaction force. The top block 44 is slidably connected to the inner wall of the body 1. The left end of the lower surface of the limiting block 41 is set as an inclined surface. When the inclined surface is compressed, the limiting block 41 will move to the right. The difference between the thickness of the locking block 35 and the depth of the locking groove 33 is equal to the height difference of the inclined surface of the limiting block 41.
[0039] Working principle: First, place the machine body 1 at the mounting hole on the mounting device, then move the mounting block 31 to the position aligned with the mounting hole, and then tighten the mounting bolt 2.
[0040] During the tightening of mounting bolt 2, the body 1 and the mounting device will be gradually fixed together. When mounting bolt 2 is tightened, it will also press the arc surface of the locking block 35, causing the locking block 35 and the moving ring 34 to move upward. The upward-moving locking block 35 will release the obstruction of mounting bolt 2. The upward-moving moving ring 34 will compress the compression spring 36 to generate a reaction force. When the moving ring 34 moves upward, it will also press the inclined surface of the limiting block 41. The right end of the limiting block 41 will gradually insert into the limiting groove 45 to limit the mounting block 31. When the limiting block 41 is inserted into the limiting groove 45, it will not cause movement interference because the chamfer of its right end is aligned with the nearest limiting groove 45. When the limiting block 41 is inserted into the limiting groove 45, it will also push the top block 44 and the sliding plate 42 to move to the right. The sliding plate 42 moving to the right will compress the connecting spring 43 to generate a reaction force.
[0041] When the mounting bolt 2 is installed, continue to tighten the mounting bolt 2 and observe the position of the pressure rod 37 in real time. When the locking block 35 and the locking groove 33 are aligned, the reaction force of the compression spring 36 will push the moving ring 34, the locking block 35 and the pressure rod 37 downward. At this time, the locking block 35 will be inserted into the locking groove 33 to limit the mounting bolt 2 and prevent it from rotating in the opposite direction. The pressure rod 37 will also be pushed out to remind the staff.
[0042] The downward-moving moving ring 34 changes the position of the inclined surface of the compression limiting block 41. At this time, the connecting spring 43 pushes the sliding plate 42 and the top block 44 to move to the left and push the limiting block 41. However, since the thickness of the locking block 35 is greater than the depth of the locking groove 33, the limiting block 41 will not be completely pushed out of the limiting groove 45. Therefore, it can still limit the mounting block 31, ensuring the stability of the mounting point and preventing the device from shaking during subsequent use.
[0043] Furthermore, the body 1 will vibrate during use, but because the locking block 35 limits the mounting bolt 2, the mounting bolt 2 will not rotate in the opposite direction and loosen, thus maintaining stability. When disassembly is required, press the pressure rod 37 to drive the moving ring 34 and the locking block 35 to move upward. The locking block 35 will disengage from the locking groove 33. At this time, the mounting bolt 2 can be rotated in the opposite direction to unscrew it. When the mounting bolt 2 is unscrewed, the moving ring 34 will not be blocked. The force of the compression spring 36 will push the moving ring 34 to the lowest point and disengage it from the limiting block 41. At this time, the limiting block 41 will be pushed out of the limiting groove 45 by the top block 44 to release the limitation on the mounting block 31, making it convenient to adjust the position of the mounting block 31 to suit different mounting holes. The mounting holes on the mounting device are generally square, so in this technical solution, the mounting block 31 can move along the diagonal trajectory of the body 1 to present a square shape.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
