However, adjusting the two guide wheels separately is not only inefficient, but also makes the gaps between the two guide wheels and the guide rails asynchronous, thereby reducing the accuracy of the guide wheels. Therefore, a device that can synchronously adjust the gaps between the two guide wheels and the guide rails is needed. Utility Model Content

[0028] Poor guide wheel accuracy may lead to a series of adverse consequences. First, poor guide wheel accuracy will directly affect the overall performance of the equipment. For example, in a mechanical transmission system, the guide wheel is responsible for guiding, supporting and positioning moving parts such as transmission belts or chains. If the guide wheel accuracy is insufficient, it may cause the transmission belt or chain to deviate, vibrate or run unstably, which in turn affects the stability and efficiency of the entire system. Secondly, poor guide wheel accuracy may also have a negative impact on processing quality and product accuracy. During manufacturing and processing, guide wheels are often used to position and support workpieces to ensure the stability and accuracy of the processing process. If the guide wheel accuracy is poor, it may cause inaccurate positioning of the workpiece or error accumulation during the processing process, thereby affecting the quality and accuracy of the final product. In addition, poor guide wheel accuracy may also increase the maintenance cost and failure rate of the equipment. Unstable operation and increased wear of the equipment due to accuracy problems may make the equipment more prone to failure, requiring more frequent maintenance and replacement of parts, which will undoubtedly increase the maintenance cost and use cost of the equipment. Therefore, in order to ensure the stable operation of the equipment and the processing quality of the product, the manufacturing and installation accuracy of the guide wheel should be strictly controlled to avoid possible adverse consequences.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The guide wheel adjustment device of the first embodiment of the utility model is used to adjust the distance between the guide wheel 41 on the carrier and the track 1. The track 1 is arranged along the first direction. The guide wheel adjustment device includes: a base plate 2, an adjustment plate 3, a first guide assembly 4 and a second guide assembly 5. The base plate 2 is fixedly connected to the carrier. A first limiting groove 21 and a second limiting groove 22 are arranged on the base plate 2. The first limiting groove 21 and the second limiting groove 22 are symmetrical. The symmetry axis of the first limiting groove 21 and the second limiting groove 22 is the center line of the track 1. The distance between the first limiting groove 21 and the second limiting groove 22 gradually increases or decreases along the first direction, that is, the first limiting groove 21 and the second limiting groove 22 are both inclined relative to the track 1; the adjustment plate 3 is arranged on the base plate 2, and the position where the adjustment plate 3 is fixed on the base plate 2 can be Adjustment along the first direction, the adjustment plate 3 is provided with a first gear slot 31 and a second gear slot 32, the first gear slot 31 and the second gear slot 32 are symmetrical, the axis of symmetry of the first gear slot 31 and the second gear slot 32 is the center line of the track 1, the orthographic projection of the first gear slot 31 on the bottom plate 2 and the first limiting slot 21 are arranged crosswise, and the orthographic projection of the second gear slot 32 on the bottom plate 2 and the second limiting slot 22 are arranged crosswise; the first guide assembly 4 and the second guide assembly 5 both include guide wheels 41, the first guide assembly 4 and the second guide assembly 5 are arranged along the second direction, respectively arranged on both sides of the track 1, the second direction is perpendicular to the first direction, the first guide assembly 4 is arranged in the first limiting slot 21 and the first gear slot 31, and the second guide assembly 5 is arranged in the second limiting slot 22 and the second gear slot 32. Taking the first guide assembly 4 as an example, the first guide assembly 4 can move along the first limiting slot 21 in the first limiting slot 21, and the first guide assembly 4 can also move along the first gear slot 31 in the first gear slot 31. When the first limit groove 21 and the first gear groove 31 are arranged crosswise, the first guide assembly 4 will be fixed at the intersection of the two. That is to say, when the first limit groove 21 and the first gear groove 31 intersect and are relatively fixed, the first guide assembly 4 is fixed at the intersection. When the first gear groove 31 and the first limit groove 21 move relative to each other, the intersection between the two will move, and at this time, the first guide assembly 4 will move along the intersection of the two. That is to say, when the adjustment plate 3 moves along the first direction to adjust the fixed position between the bottom plate 2 and the adjustment plate 3, the first guide assembly 4 and the second guide assembly 5 will move along the first limit groove 21 and the second limit groove 22 at the same time. Since the first limit groove 21 and the second limit groove 22 are symmetrically arranged, the first gear groove 31 and the second gear groove 32 are symmetrically arranged, and the symmetry axis is the center line of the track 1, when the adjustment plate 3 is moved to adjust the distance between the first guide assembly 4 and the second guide assembly 5, it is ensured that the symmetry axis between the first guide assembly 4 and the second guide assembly 5 is also the center line of the track 1. That is to say, it is ensured that the distances between the two guide wheels 41 and the track 1 are equal.The center line of the track 1 is a line located in the middle of two contact surfaces between the track 1 and the two guide wheels 41 and is parallel to the first direction.

[0030] It should be noted that when the carrier is set on the track 1, there are multiple devices on the carrier to limit the movement of the carrier. Therefore, the carrier can only move in a first direction relative to the track 1, but cannot move in a second direction relative to the track 1. Therefore, when setting the carrier or when setting the base plate 2 on the carrier, the symmetry axes of the first limit groove 21 and the second limit groove 22 on the base plate 2 need to be set to coincide with the center line of the track 1.

[0031] On the other hand, in some usage scenarios, the guide wheel 41 needs to be attached to the track 1, and even a certain pre-tightening force needs to be provided between the guide wheel 41 and the track 1. At this time, by adjusting the guide wheel 41 through the adjustment plate 3, the adjustment of the guide wheel 41 on the track 1 side can also be made more synchronous, and the efficiency of adjusting the guide wheel 41 is improved at the same time.

[0032] In the prior art, when the guide wheel 41 needs to be adjusted, a single guide wheel 41 needs to be adjusted independently, which is not only less efficient, but also causes the adjustment of the corresponding guide wheels 41 on both sides of the track 1 to be asynchronous. That is, the distance between the two guide wheels 41 corresponding to the two sides of the track 1 and the track 1 is inconsistent, or the preload force between the two guide wheels 41 corresponding to the two sides of the track 1 and the track 1 is inconsistent, etc. This solution synchronously adjusts the two guide wheels 41 corresponding to the two sides of the track 1, which not only improves the positioning accuracy of the guide wheel 41, but also effectively avoids the problem of uneven force on the guide wheels 41 on the left and right sides of the track 1, thereby increasing the service life of the guide wheels 41 in the working state.

[0033] According to some embodiments of the utility model, at least two fixing grooves 33 are provided on the adjustment plate 3, and the fixing grooves 33 are extended along the first direction. The bottom plate 2 is provided with a threaded hole 23, and the bolt passes through the fixing groove 33 and is arranged in the threaded hole 23, so that the adjustment plate 3 is fixed on the bottom plate 2, and the fixing position between the bolt and the fixing groove 33 is adjustable. By providing two fixing grooves 33, it can be ensured that the adjustment plate 3 can be moved and adjusted more stably along the first direction, and it can also be ensured that the symmetry line of the first gear groove 31 and the second gear groove 32 is the center line of the track 1. Specifically, the first gear groove 31 can also be arranged along the second direction.

[0034] According to some embodiments of the utility model, the angle between the orthographic projection of the first limit groove 21 on the bottom plate 2 and the orthographic projection of the first gear groove 31 on the bottom plate 2 is 45°. At this time, whether increasing the distance between the two guide wheels 41 or reducing the distance between the guide wheels 41 is relatively smooth, the friction between the guide assembly and the first limit groove 21 or the first gear groove 31 is relatively small, and the guide wheel 41 can be adjusted more conveniently.

[0035] According to some embodiments of the utility model, the first guide assembly 4 further includes a rotating shaft 42, the guide wheel 41 on the first guide assembly 4 is rotatably arranged on the rotating shaft 42, the rotating shaft 42 is arranged in the first limiting groove 21 and the first gear groove 31, and the rotating shaft 42 is provided with a first limiting surface and a second limiting surface, the first limiting surface abuts against the side of the first limiting groove 21 to limit the rotation of the rotating shaft 42 relative to the first limiting groove 21, and the second limiting surface abuts against the side of the first gear groove 31 to limit the rotation of the rotating shaft 42 relative to the first gear groove 31. The two limiting surfaces are provided to prevent the rotating shaft 42 from rotating relative to the bottom plate 2 or the adjustment plate 3. At the same time, the limiting surfaces can also increase the contact area between the rotating shaft 42 and the bottom plate 2 and the adjustment plate 3, so that the limiting of the rotating shaft 42 is more accurate and stable.

[0036] According to some embodiments of the utility model, a first boss and a second boss are further provided on the rotating shaft 42, and the first limiting surface and the second limiting surface are both provided between the first boss and the second boss, the first boss abuts against the side of the bottom plate 2 away from the adjusting plate 3, and the second boss abuts against the side of the adjusting plate 3 away from the bottom plate 2. The bottom plate 2 and the adjusting plate 3 are clamped by providing two bosses to prevent the rotating shaft 42 from moving axially relative to the first limiting groove 21 and the first gear groove 31. The first boss and the second boss are provided on one side of the rotating shaft 42, and the guide wheel 41 is provided on the other side of the rotating shaft 42, and the first boss is on the side of the second boss away from the guide wheel 41. The first boss can be provided as a detachable shaft retaining ring to facilitate the installation of the guide assembly.

[0037] According to some embodiments of the present invention, an adjustment plate 3, a first limiting groove 21, and a second limiting groove 22 are provided at both ends of the bottom plate 2 along the first direction. Providing two adjustment plates 3 at both ends of the bottom plate 2 allows more guide wheels 41 to be provided, making the guidance of the carrier smoother.

[0038] According to some embodiments of the utility model, the distance between the first limiting groove 21 and the second limiting groove 22 gradually increases in the direction away from the other adjustment plate 3, and the angle between the extension direction of the first limiting groove 21 and the center line of the track 1 is not greater than 45°. This avoids excessive resistance to the adjustment plate 3 during movement and adjustment due to an excessively large angle, or even causing a jam.
