Description

Technical Field

[0001] The invention relates to the field of regulators, and more particularly to a dual-axis automatic angle regulator. Background Art

[0002] In the field of assembly, it is often necessary to assemble and fix an object with specific position requirements to another supporting object, and the position requirements are very accurate. However, the installation position of the supporting object cannot meet the position accuracy requirements of the installed object, especially when the installation surfaces of the two objects are not parallel and there is an angle difference. For example, a radar device is installed on a body sheet metal. In this case, the installation surface of the radar is not actually parallel to the body sheet metal surface, and the distance between the installation surface of the radar and the body sheet metal surface is also uncertain, with an angle difference and position deviation.

[0003] When the existing regulator installs the mounting surface of the radar on the body sheet metal surface, it can only adjust the distance between the mounting surface and the body sheet metal surface, and it is difficult to adjust the situation where the mounting surface is not parallel to the body sheet metal surface. Summary of the invention

A second pin is provided between the adjusting member and the second cylinder, and the adjusting member and the second cylinder are rotatably connected via the second pin.

[0010] As a further improvement of the present invention, an elastic component is provided on the first cylinder or the second cylinder, and the elastic component contacts with the second cylinder or the first cylinder under the action of elastic force.

[0011] As a further improvement of the present invention, the regulator also includes a fixing assembly, through which the first cylinder is fixed to the second component, and the fixing assembly includes a connecting column, which is fixedly connected to the first cylinder, and the connecting column is screwed, clamped or riveted to the second component.

[0012] As a further improvement of the present invention, a connecting hole is provided on the second component, the fixing assembly also includes a fixing nut, the connecting column includes a stop section for inserting into the connecting hole and a threaded section for cooperating with the fixing nut, the stop section is located between the threaded section and the first cylinder, the stop section is adapted to the connecting hole and the stop section cannot rotate in the connecting hole, and after the stop section is inserted into the connecting hole, the second component is locked by the fixing nut.

[0013] To achieve the above objectives, the present invention provides the following technical solutions: a dual-axis automatic angle adjustment device, comprising the aforementioned dual-axis automatic angle adjuster, characterized in that: there are at least two adjusters, and the adjusters simultaneously fix the first component and the second component.

[0014] As a further improvement of the present invention, the rotation direction of the transmission thread of at least one of the regulators is opposite to the rotation direction of the transmission thread of the other regulators.

[0016] The beneficial effects of the present invention are as follows: through the setting of the angle adjustment component, the fixing part and the second cylinder can cross-rotate.

Therefore, the regulator can be used to connect two components and adjust the distance and angle difference between the two components.

[0018] And because the fixing piece is connected to the first component and the first cylinder is arranged on the first component, the transmission thread, the first pin shaft and the second pin shaft do not bear the locking force, the force they bear is small, and they are not easily damaged, which is beneficial to improving the service life of the regulator.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0028] Embodiment 1:

[0029] Reference Figure 1 As shown, a dual-axis automatic angle adjustment device of the present embodiment is used to connect a first component 1 and a second component 2. A first cylinder 21 is provided on the second component 2. The first cylinder 21 can be fixed to the second component 2 by screwing, riveting, etc., or can be integrally formed with the second component 2. In the present embodiment, the first cylinder 21 and the second component 2 are integrally formed.

[0030] Reference Figure 1 , Figure 5 , Figure 6 As shown, the regulator includes an angle adjustment component 3, which includes a fixing member 31, an adjusting member 32 and a second cylinder 33. The fixing member 31 is used to be fixed to the first component 1. The second cylinder 33 is connected to the first cylinder 21 through a transmission thread 22. When the second cylinder 33 approaches or moves away from the first cylinder 21, the second cylinder 33 rotates under the guidance of the transmission thread 22.

[0031] Reference Figure 1 , Figure 5 , Figure 6As shown, specifically, the first cylinder 21 can be located outside or inside the second cylinder 33, a concave thread or a convex thread can be provided on the first cylinder 21, and a convex thread or a concave thread is correspondingly provided on the second cylinder 33, and a plurality of transmission threads 22 can be provided, and a plurality of transmission threads 22 can improve stability. In this embodiment, the first cylinder 21 is located inside the second cylinder 33, a convex thread is provided on the first cylinder 21, and a concave thread is provided on the second cylinder 33, and the transmission thread 22 is a trapezoidal thread and is provided in four threads, and the four transmission threads 22 are provided along the central axis of the first cylinder 21.

[0032] Reference Figure 1 , Figure 5 As shown, an elastic member 37 is provided on the first barrel 21 or the second barrel 33, and the elastic member 37 conflicts with the second barrel 33 or the first barrel 21 under the action of elastic force. Specifically, the elastic member 37 can increase the friction between the first barrel 21 and the second barrel 33, which is conducive to avoiding easy separation due to too small friction between the two during transportation and storage. And when the first barrel 21 and the second barrel 33 are stretched or squeezed by external force, they can overcome the friction and move relative to each other. Multiple elastic members 37 can be provided. In the present embodiment, two elastic members 37 are provided, both of which are provided on the second barrel 33.

[0033] Reference Figure 1 , Figure 6 As shown, a first pin shaft 34 is provided between the adjusting member 32 and the fixing member 31, and the adjusting member 32 and the fixing member 31 are rotatably connected through the first pin shaft 34. A second pin shaft 35 is provided between the adjusting member 32 and the second cylinder 33, and the adjusting member 32 and the second cylinder 33 are rotatably connected through the second pin shaft 35. The first pin shaft 34, the second pin shaft 35 and the central axis of the second cylinder 33 are perpendicular to each other.

[0034] Reference Figure 1 , Figure 6 As shown, specifically, a socket is provided between the adjusting member 32 and the fixing member 31, and the first pin 34 is located in the two sockets. A socket is also provided between the adjusting member 32 and the second cylinder 33, and the second pin is located in the two sockets. The fixing member 31 on the angle adjustment assembly 3 can rotate relative to the second cylinder 33 through the adjusting member 32, the first pin 34, and the second pin 35. When the second cylinder 33 rotates relative to the first cylinder 21, the entire angle adjustment assembly 3 rotates synchronously with the second cylinder 33.

[0035] Reference Figure 1 , Figure 6As shown, the adjusting member 32 is configured to be rotatable relative to the fixing member 31 and the second cylinder 33. In this embodiment, the adjusting member 32 is configured to be annular, the adjusting member 32 is located in the second cylinder 33, and the fixing member 31 is located in the adjusting member 32. Two first pin shafts 34 and two second pin shafts 35 are provided, and the two first pin shafts 34 are respectively provided on opposite sides of the adjusting member 32, and the two first pin shafts 34 are located on the same straight line, and the two second pin shafts 35 are respectively provided on the other two sides of the adjusting member 32, and the two second pin shafts 35 are located on the same straight line. The first pin shaft 34 and the second pin shaft 35 are located on the same plane.

[0036] Reference Figure 1 , Figure 6 As shown, specifically, a first latch and a second latch are respectively arranged on both sides of the adjusting member 32, which is conducive to improving the connection tightness between the adjusting member 32 and the fixing member 31 and the second cylinder 33, and at the same time makes the relative rotation between the adjusting member 32 and the fixing member 31 and the second cylinder 33 more stable and reliable. The first latch and the second latch are located on the same plane, which is conducive to making the adjusting member 32, the fixing member 31 and the second cylinder 33 more compact and reducing the volume.

[0037] Reference Figure 1 As shown, the fixing member 31 is fixed to the first member 1 by a bolt 36. The specific fixing method in this embodiment is as follows: the first member 1 is provided with a first adjustment hole 11, the fixing member 31 is provided with a threaded hole, and the fixing member 31 is integrally formed with a contact portion, and the contact portion is used to contact the first member 1. The bolt 36 passes through the first adjustment hole 11 and is screwed with the threaded hole. The bolt 36 is a flange bolt 36. When screwed, the flange on the flange bolt 36 and the contact portion clamp the first member 1, thereby realizing the connection and fixation of the fixing member 31 with the first member 1. There is a first adjustment gap 12 between the screw rod of the bolt 36 and the first adjustment hole 11. The first adjustment gap 12 is used to allow the bolt 36 to move freely in the first adjustment hole 11 in a direction perpendicular to the axis of the bolt 36 when connecting the first member 1 and the second member 2, thereby adjusting the lateral deviation between the first adjustment hole 11 on the first member 1 and the threaded hole on the fixing member 31, thereby realizing the adjustment of the position deviation in the three-axis direction in a 90-degree rectangular coordinate system.

[0038] Working principle:

[0039] When connecting the first component 1 and the second component 2, the second sleeve is connected to the first sleeve through the transmission thread 22 and is located between the two components. The fixing member 31 is rotated to align with the first adjustment hole 11 on the first component 1, and then the bolt 36 is passed through the first adjustment hole 11 and screwed into the fixing member 31. When the bolt 36 is continuously screwed into the fixing member 31, the second sleeve is moved away from the first sleeve because the distance between the first component 1 and the second component 2 remains unchanged. In the process of the second sleeve moving away from the first sleeve, due to the guiding effect of the transmission thread 22, the second sleeve drives the adjusting member 32 and the fixing member 31 to rotate around the central axis of the first sleeve until the fixing member 31 contacts the first component 1. Therefore, only by tightening the bolt 36, the first sleeve and the second sleeve can be automatically extended to adapt to the distance between the first component 1 and the second component 2. When the bolt 36 is tightened on the fixing member 31 , since the fixing member 31 is fixed to the first component 1 , the fixing member 31 no longer rotates, so the first sleeve and the second sleeve do not rotate, and the distance between the first sleeve and the second sleeve no longer changes.

[0040] Embodiment 2:

[0041] Reference Figure 2 , Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the regulator also includes a fixing component 4, the first cylinder 21 is fixed to the second component 2 through the fixing component 4, the fixing component 4 includes a connecting column 41, the connecting column 41 is fixedly connected to the first cylinder 21, and the connecting column 41 and the second component 2 are screwed, clamped or riveted.

[0042] Reference Figure 3 As shown, the connecting column 41 is clamped with the second component 2. A clamp head is provided on the connecting column 41, and a clamp hole is provided on the second component 2. The clamp head is inserted into the clamp hole to achieve clamping. Figure 2 As shown, the connecting body is screwed with the second member 2, and the specific screwing method is: the second member 2 is provided with a connecting hole 23, the fixing assembly 4 also includes a fixing nut 42, the connecting column 41 includes a stop section 411 for inserting into the connecting hole 23 and a threaded section 412 for cooperating with the fixing nut 42, the stop section 411 is located between the threaded section 412 and the first cylinder 21, the stop section 411 is adapted to the connecting hole 23 and the stop section 411 cannot rotate in the connecting hole 23, and the stop section 411 is inserted into the connecting hole 23 and locks the second member 2 through the fixing nut 42. The connecting hole 23 can be set as a waist-shaped hole or a polygonal hole, and the stop section 411 is set as a shape adapted to the connecting hole 23. In this embodiment, the connecting hole 23 is a square hole, and the stop section 411 is also set as a square. The setting of the stop section 411 makes it possible for the connecting column 41 to not rotate relative to the connecting hole 23 when the fixing nut 42 is tightened.

[0043] Embodiment 3:

[0044] Reference Figure 4 As shown, the difference between this embodiment and embodiment 1 is that the fixing member 31 is fixed to the first component 1 by a bolt 36 , a second adjustment hole 311 is provided on the fixing member 31 , and a second adjustment gap 312 is provided between the screw rod of the bolt 36 and the second adjustment hole 311 .

[0045] Reference Figure 4 As shown, specifically, the fixing member 31 is integrally formed with a resisting portion, and the resisting portion is used to resist the first member 1. A through hole is provided on the first member 1, and the bolt 36 is a flange bolt 36, and the bolt 36 passes through the second adjustment hole 311 and the through hole respectively and is screwed through a nut. When screwed, the flange on the flange bolt 36 and the resisting portion clamp the first member 1, thereby realizing the connection and fixation of the fixing member 31 and the first member 1. There is a second adjustment gap 312 between the screw rod of the bolt 36 and the second adjustment hole 311. The second adjustment gap 312 is used to allow the bolt 36 to move freely in the second adjustment hole 311 in a direction perpendicular to the axis of the bolt 36 when connecting the first member 1 and the second member 2, so as to adjust the lateral deviation between the through hole on the first member 1 and the second adjustment hole 311 on the fixing member 31, so as to realize the adjustment of the position deviation in the three-axis direction under the 90-degree rectangular coordinate system.

[0046] Embodiment 4:

[0047] Reference Figure 7 As shown, a dual-axis automatic angle adjustment device comprises at least two dual-axis automatic angle adjusters in Embodiment 1, Embodiment 2 or Embodiment 3. The adjusters fix the first component 1 and the second component 2 at the same time.

[0048] Reference Figure 7 As shown, specifically, when only one adjuster is used, since the fixing member 31 and the second cylinder 33 can rotate relative to each other, the adjuster cannot lock the angle between the first component 1 and the second component 2. When the two components are subjected to external force so that the angle between the two components changes, the fixing member 31 in the adjuster and the second cylinder 33 will rotate relative to each other. When only two adjusters are used, the adjusters basically lock the first component 1 and the second component 2, and the first component 1 and the second component 2 can only rotate relative to the line between the two adjusters when subjected to external force. When three adjusters are used, and the three adjusters are not on the same straight line, the relative rotation between the first component 1 and the second component 2 is completely locked, the first component 1 cannot rotate relative to the second component 2, and the connection is more stable and reliable.

[0049] The rotation direction of the transmission thread 22 of at least one adjuster is opposite to the rotation direction of the transmission thread 22 of the other adjusters. Specifically, since the transmission thread 22 has a gap, after the first component 1 and the second component 2 are connected, due to the gap of the transmission thread 22, the first component 1 and the second component 2 may still move slightly relative to each other, which is not conducive to the precise positioning between the first component 1 and the second component 2. When the rotation directions of the transmission threads 22 between the adjusters are different, the slight relative movement between the first component 1 and the second component 2 caused by the gap of the transmission thread 22 can be avoided, thereby improving the installation accuracy between the first component 1 and the second component 2.

[0050] When multiple regulators are used, the rotation direction of the two regulators farthest away is set to be opposite to the rotation direction of the other regulators, so that the clearance of the transmission thread 22 is least affected and the installation accuracy is the highest. Figure 7 As shown, in this embodiment, four adjusters are used to connect the first component 1 and the second component 2, and the four adjusters are arranged at four corners. The transmission threads 22 of two adjusters located on the same diagonal have the same rotation direction, and the transmission threads 22 of two adjusters located on different diagonals have opposite rotation directions.

[0051] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
