Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, in particular to a bracket for conveniently adjusting the position of a light target. Background Art

[0002] At present, the shafting system widely used in various large cargo ships is usually arranged with the rear bearing of the stern tube, the front bearing and the intermediate bearing to support the stern shaft and the intermediate shaft. The precision control of the shafting installation is achieved by positioning the front and rear bearings of the stern tube by the shafting wire and locating the position of the intermediate bearing and the main engine by the load method.

[0003] Among them, the center position of the light target needs to be adjusted in the up and down and left and right directions during the axis pulling and lighting stages. However, due to its own structural characteristics, the existing light target mounting bracket needs to remain loose in one direction when adjusting the position in the other direction to ensure that the light target can move. The adjustment process is relatively cumbersome and difficult to operate, and the adjustment accuracy is difficult to guarantee, which can easily cause adjustment errors. Summary of the invention

[0004] In view of the above problems existing in the prior art, an embodiment of the present invention provides a bracket for conveniently adjusting the position of a light target, so as to solve the technical problems existing in the prior art that the light target is difficult to adjust and the adjustment accuracy is insufficient.

[0005] The embodiment of the present invention provides a bracket for conveniently adjusting the position of a light target, comprising:

[0006] A base plate, a first movable plate is slidably mounted on one side of the base plate, the first movable plate can move relative to the base plate in a first direction and can be fixed relative to the base plate when moved into place, a second movable plate is slidably mounted on a side of the first movable plate away from the base plate, the second movable plate can move relative to the first movable plate in a second direction and can be fixed relative to the first movable plate when moved into place, the first direction is perpendicular to the second direction, and the second movable plate, the first movable plate and the middle of the base plate are all provided with light holes allowing laser to pass through.

[0007] In one embodiment, the first direction is a horizontal direction, and the second direction is a vertical direction.

[0008] In one embodiment, relative sliding is achieved between the base plate and the first movable plate, and between the first movable plate and the second movable plate via cross roller guide rails.

[0009] In one embodiment, it further includes:

[0010] A driving component for driving the first moving plate or the second moving plate to move;

[0011] The driving assembly includes a rack and a micro gear. The rack is fixedly mounted on a relatively sliding side plate, and the micro gear is rotatably mounted on a relatively fixed side plate. The micro gear is meshed with the rack, and the rack is driven to move by rotating the micro gear, thereby driving the plate fixed to the rack to move.

[0012] In one embodiment, it further includes:

[0013] A locking assembly for limiting the movement of the first movable plate or the second movable plate;

[0014] The locking assembly includes a locking plate and a locking bolt. The locking plate is fixedly mounted on a relatively fixed side plate body. A strip hole is formed on the locking plate, and the extending direction of the strip hole is the same as the moving direction of the relatively sliding side plate body. The locking bolt passes through the strip hole that is clearance-matched with the strip hole and extends to the relatively sliding side plate body, and is screwed into a threaded hole on the relatively sliding side plate body.

[0015] When the locking bolt is screwed inward until it abuts against the locking plate, the plate body on the relatively movable side is in a fixed state;

[0016] When the locking bolt is screwed outward until the locking bolt is disengaged from the locking plate, the plate body on the relatively movable side is in a movable state.

[0038] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0039] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to determine the true intent based on the user's historical operations and to avoid unnecessary or redundant details that make the present application unclear. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but are merely used as the basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0040] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0041] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The embodiments are only used to explain the present invention and are not used to limit the scope of the present invention. Figure 1-11 , the preferred embodiments of the present invention are further described in detail:

[0042] like Figure 1-9 As shown, an embodiment of the present invention provides a bracket for conveniently adjusting the position of a light target, comprising:

[0043] A base plate 1, a first movable plate 2 is slidably mounted on one side of the base plate 1, the first movable plate 2 can move relative to the base plate 1 along a first direction and can be fixed relative to the base plate 1 when the movement is in place, a second movable plate 3 is slidably mounted on the side of the first movable plate 2 away from the base plate 1, the second movable plate 3 can move relative to the first movable plate 2 along a second direction and can be fixed relative to the first movable plate 2 when the movement is in place, the first direction is perpendicular to the second direction, and a light hole is provided in the middle of the second movable plate 3, the first movable plate 2 and the base plate 1 to allow the laser to pass through;

[0044] Among them, the first direction and the second direction only need to be two directions perpendicular to each other to conveniently realize the position adjustment of the light target, but considering the working habits, it is better to set the first direction and the second direction in the horizontal and vertical directions, that is, the first direction can be the horizontal direction or the vertical direction, and the second direction is adjusted for applicability corresponding to the first direction. On this basis, considering that the plates may have a self-sliding tendency due to problems such as their own weight, in order to weaken this unfavorable tendency, in one embodiment, the first direction is defined in the horizontal direction, and the second direction is correspondingly defined in the vertical direction. At this time, the second movable plate 3 will only have a sliding tendency relative to the first movable plate 2 due to the self-weight of its own plate body, and there will be no problem of the first movable plate 2 and the second movable plate 3 having a sliding tendency relative to the base plate 1 due to the self-overlapping of the plate bodies;

[0045] Considering the smooth sliding, convenient purchasing and simple installation and disassembly, in one embodiment, the base plate 1 and the first movable plate 2, and the first movable plate 2 and the second movable plate 3 are all relative to each other through the cross roller guide rail 4;

[0046] In order to realize the movement and adjustment of the plate body more conveniently and quickly, in one embodiment, the bracket further includes a driving component for driving the first moving plate 2 or the second moving plate 3 to move;

[0047] like Fig.10 As shown, the driving assembly includes a rack 5 and a micro gear 8, wherein the rack 5 is fixedly mounted on a relatively sliding side plate, and the micro gear 8 is rotatably mounted on a relatively fixed side plate, and the micro gear 8 is meshed and connected with the rack 5, and the rack 5 is driven to move by rotating the micro gear 8, thereby driving the plate fixed to the rack 5 to move;

[0048] Specifically, between the base plate 1 and the first movable plate 2, the rack 5 is fixedly mounted on the first movable plate 2, and the micro-gear 8 is mounted on the base plate 1 through a connecting block 6 and a fixing sleeve 7, wherein the micro-gear 8 includes a gear portion at the inner end and a rotating shaft integrally connected to the gear portion, the outer diameter of the rotating shaft is smaller than the outer diameter of the gear portion, a larger hole is provided in the middle of the connecting block 6 to ensure that the gear portion can be smoothly inserted when the micro-gear 8 is installed, in order to prevent the gear portion from falling out and to ensure the stability of the rotation of the gear portion, a fixing sleeve 7 is correspondingly sleeved on the rotating shaft, and the through hole in the middle of the fixing sleeve 7 matches the outer diameter of the rotating shaft, and the fixing sleeve 7 is inserted into the through hole in the middle of the connecting block 6, which can block the gear portion to prevent it from falling out, and on the other hand, it can also limit the excessive shaking of the rotating shaft to ensure its stable rotation, and in order to facilitate the twisting of the rotating shaft, a rotating handwheel 9 is fixedly mounted at the free end of the outer side of the rotating shaft;

[0049] Similarly, between the first movable plate 2 and the second movable plate 3, the rack 5 is fixedly mounted on the second movable plate 3, and the micro-gear 8 is mounted on the first movable plate 2 through a connecting block 6 and a fixing sleeve 7, wherein the micro-gear 8 includes a gear portion at the inner end and a rotating shaft integrally connected to the gear portion, the outer diameter of the rotating shaft is smaller than the outer diameter of the gear portion, a larger hole is provided in the middle of the connecting block 6 to ensure that the gear portion can be smoothly inserted when the micro-gear 8 is installed, in order to prevent the gear portion from falling out and to ensure the stability of the rotation of the gear portion, a fixing sleeve 7 is correspondingly sleeved on the rotating shaft, and the through hole in the middle of the fixing sleeve 7 matches the outer diameter of the rotating shaft, and the fixing sleeve 7 is inserted into the through hole in the middle of the connecting block 6, which can block the gear portion to prevent it from falling out, and on the other hand, it can also limit the excessive shaking of the rotating shaft to ensure its stable rotation, and in order to facilitate the twisting of the rotating shaft, a rotating handwheel 9 is fixedly mounted at the free end of the outer side of the rotating shaft;

[0050] In order to further improve the position stability of the optical target after the bracket is adjusted into place, in one embodiment, the bracket further includes a locking component for limiting the movement of the first movable plate 2 or the second movable plate 3;

[0051] like Fig.11 As shown, the locking assembly includes a locking plate 11 and a locking bolt 12. The locking plate 11 is fixedly mounted on a relatively fixed side plate body. A strip hole 13 is provided on the locking plate 11, and the extending direction of the strip hole 13 is the same as the moving direction of the relatively sliding side plate body. The locking bolt 12 passes through the strip hole 13 with a clearance fit therewith and extends to the relatively sliding side plate body, and is screwed into the threaded hole on the relatively sliding side plate body.

[0052] When the locking bolt 12 is screwed inward until it abuts against the locking plate 11, the plate body on the relatively movable side is in a fixed state;

[0053] When the locking bolt 12 is screwed outward until the locking bolt 12 is disengaged from the locking plate 11, the plate body on the relatively movable side is in a movable state;

[0054] Specifically, between the base plate 1 and the first movable plate 2, the locking plate 11 is fixedly mounted on the base plate 1, and the locking bolt 12 is inserted into the threaded hole of the first movable plate 2;

[0055] Similarly, between the first movable plate 2 and the second movable plate 3, the locking plate 11 is fixedly mounted on the first movable plate 2, and the locking bolt 12 is inserted into the threaded hole of the second movable plate 3;

[0056] Considering the lightness and durability, the base plate 1, the first movable plate 2 and the second movable plate 3 are all made of aluminum alloy, and a stainless steel bushing 10 for mounting a light target is fixedly provided at the light hole in the middle of the second movable plate 3. Since the bushing 10 needs to frequently install and remove the light target, in order to ensure its durability, the bushing 10 is correspondingly set to be made of stainless steel;

[0057] Of course, in order to facilitate the installation of the rack 5, an avoidance groove is correspondingly opened on the plate body at the installation position of the rack 5. During installation, the rack 5 can be initially positioned by simply inserting the rack 5 into the groove. Similarly, in order to facilitate the installation of the cross roller guide 4, the corresponding plate body is also provided with an avoidance groove or protrusion at the installation position. Among them, the various parts of the bracket are connected by screws. Taking the installation and fixation of the cross roller guide 4 as an example, the two guide rails of each group of cross roller guides 4 are respectively provided with threaded through holes and non-threaded through holes, so as to facilitate the installation of screws used to fix the cross roller guide 4 in the stacked structure, that is, one side of the base plate 1 is defined as On the inside, one side of the second movable plate 3 is defined as the outside. Since it is more convenient to install the screws from the outside to the inside, the parts located on the outside of the screws are set as through holes without threads, and the parts located on the inside of the screws are set as through holes with threads. This will reduce the screwing amount of the screws while ensuring the stability of the structure, thereby facilitating the installation and disassembly operations. Similarly, under the premise of ensuring that the structure can be stably installed, the through holes for the screws in the other parts can also be set according to this principle. Of course, the end of the screw needs to be screwed into the countersunk hole to avoid it protruding from the surface of the plate. On the one hand, it is more beautiful, and on the other hand, it will not affect the free sliding adjustment of the plate.

[0058] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
