Description

Technical Field

[0001] This utility model relates to the field of laser rangefinder technology, and in particular to a pendulum structure for a laser line projector and the laser line projector itself. Background Technology

[0002] The existing laser line projector's pendulum bearing structure has a technical defect: a high rate of failure in resetting accuracy (7%-8%).

[0003] Existing traditional pendulum bearing structures employ a step-by-step, double-step bearing seat design in their manufacturing process. This requires two adjustments to the turntable's orientation during machining, with each bearing seat being machined separately. This process suffers from the problem of accumulated turntable rotation accuracy errors, making it difficult to guarantee the concentricity of the two bearing seats and ultimately affecting the reset accuracy of the pendulum assembly.

[0004] Meanwhile, existing bearing structures typically employ a single-point adhesive hole design, resulting in slow adhesive penetration and requiring a longer adhesive penetration time during assembly to ensure adhesion between the bearing and the pendulum. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to solve the technical problem of two bearing holes being misaligned in the prior art, this utility model provides a swing body structure for a laser line projector and a laser line projector, which is made by boring two bearing holes in the same direction, avoiding the accumulation of turntable rotation accuracy during the processing and ensuring the concentricity of the two bearing holes.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a swing body structure of a laser line projector, including a swing body frame, the swing body frame is provided with bearing holes arranged along the x-axis, the bearing holes are symmetrically arranged on the swing body frame, and the bearing holes are used to assemble bearings, and the two bearing holes are straight through holes that are coaxially machined in one piece.

[0007] This utility model provides a swing body structure for a laser line projector, in which two bearing holes can be directly bored in the same direction during the machining process. The machining process does not accumulate the rotational accuracy of the equipment's turntable, ensuring the concentricity of the bearing assembly into the bearing hole.

[0008] Furthermore, in order to accelerate the glue penetration speed and improve assembly efficiency, the swing frame is also provided with glue dispensing holes. The glue dispensing holes are located outside the bearing holes and are connected to the bearing holes. The glue flowing into the glue dispensing holes flows along the gap between the bearing holes and the bearing. The number of glue dispensing holes connected to each bearing hole is at least 2.

[0009] Furthermore, in order to further optimize the glue penetration speed, the glue dispensing hole extends along the y-axis to the upper and lower ends of the bearing hole.

[0010] Furthermore, in order to ensure that the adhesive flows fully between the bearing hole and the outer ring, there are two dispensing holes, which are symmetrically distributed vertically along the axis of the bearing hole.

[0011] Furthermore, in order to ensure that the adhesive fully coats the outer ring, there is a gap between the bearing hole and the outer ring of the bearing, and the adhesive flows circumferentially from the upper and lower ends of the bearing hole along the gap.

[0012] Furthermore, a large shaft is connected between the inner rings of the bearings in the two bearing holes, with both ends of the large shaft extending out of the bearing holes.

[0013] Furthermore, in order to lock the inner ring axially, the main shaft has a stepped structure, and the outer end of the main shaft is connected to a parallel ring, which presses the inner ring of the bearing onto the stepped structure.

[0014] Furthermore, in order to enable the installation of the inner ring, the middle part of the main shaft is also provided with a positioning hole for installing the inner ring.

[0015] Furthermore, in order to ensure that the main shaft can be installed into the swing frame, the outer diameter of the widest part of the main shaft is smaller than the inner diameter of the bearing hole.

[0016] The technical solution adopted by this utility model to solve its technical problem is: a laser line projector, including the above-mentioned pendulum structure.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The pendulum structure of the laser line projector of this utility model and the laser line projector form bearing holes by boring in the same direction. During the processing, the concentricity of the two bearing holes can be guaranteed, thereby achieving the concentricity between the bearings after installation, effectively reducing the failure rate of the reset accuracy of the pendulum component, reducing the failure rate from 7%-8% to 2%-3%.

[0019] 2. The pendulum structure and laser line projector of this utility model adopt a double glue hole design, which can accelerate the glue penetration speed, effectively improve assembly efficiency, and achieve better wrapping of the bearing. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Example 1, as Figure 1 and Figure 2 As shown, a swing body structure for a laser line projector includes a swing body frame 1, on which bearing holes 2 are provided along the x-axis. The bearing holes 2 are symmetrically arranged on the swing body frame 1, and bearings 4 are installed within the bearing holes 2. The two bearing holes 2 are coaxial through holes machined in one operation. Because the existing swing body frame 1 has a stepped structure for the bearing holes 2, two bearing holes 2 need to be machined at each end during processing. This process accumulates the rotational accuracy of the equipment's turntable, thus reducing the concentricity of the two bearings 4. In this application, the two bearing holes 2 can be directly bored in the same direction during processing. The processing does not accumulate the rotational accuracy of the equipment's turntable, and the concentricity of the two bearing positions is guaranteed.

[0033] Example 2, based on Example 1, such as Figure 3 , Figure 4 and Figure 7 As shown, the swing frame 1 is also provided with glue dispensing holes 3. The glue dispensing holes 3 are located outside the bearing holes 2 and are connected to the bearing holes 2. The glue flowing into the glue dispensing holes 3 flows along the gap between the bearing holes 2 and the bearing 4. The number of glue dispensing holes 3 connected to each bearing hole 2 is at least two. Using two glue dispensing holes 3 to perform glue dispensing operations at the same time increases the glue penetration speed, effectively improves assembly efficiency, and the glue has better coating properties on the bearing 4.

[0034] Specifically, the dispensing holes 3 extend along the y-axis to the upper and lower ends of the bearing hole 2. Preferably, there are two dispensing holes 3, which are symmetrically distributed vertically along the axis of the bearing hole 2. There is a gap between the bearing hole 2 and the outer ring 42 of the bearing 4, and the adhesive flows circumferentially from the upper and lower ends of the bearing hole 2 along the gap. The adhesive enters from the dispensing holes 3 and flows into the bearing hole 2 along the y-axis, flowing along the inner wall of the bearing hole 2 and between the outer ring 42 of the bearing 4.

[0035] Preferably, a large shaft 5 is connected between the inner rings 41 of the bearings 4 within the two bearing bores 2, with both ends of the large shaft 5 extending out of the bearing bores 2. The large shaft 5 has a stepped structure 51, and a parallel ring 6 is connected to the outer end of the large shaft 5, pressing the inner rings 41 of the bearings 4 against the stepped structure. A positioning hole 51 for installing the inner ring is also provided in the middle of the large shaft 5. The outer diameter at the widest point of the large shaft 5 is smaller than the inner diameter of the bearing bores 2.

[0036] In the assembly of this utility model's swing body structure, the main shaft 5 is first installed into the swing body frame 1. Therefore, the outer diameter of the widest part of the main shaft 5 is smaller than the inner diameter of the bearing hole 2. Then, the bearing 4 is assembled into the bearing hole 2. After the bearing 4 is installed into the bearing hole 2, it is positioned by a stepped structure. At the same time, both ends of the main shaft 5 extend out of the bearing hole 2, and a parallel ring 6 is connected to the outer end of the main shaft 5. The bearing 4 is positioned by the parallel ring 6 and the stepped structure. Next, through the glue dispensing process described above, the glue flows around the gap between the bearing hole 2 and the outer ring 42 of the bearing 4. Finally, the inner ring assembly is completed through the positioning hole 51.

[0037] In summary, the pendulum structure of the laser line projector of this utility model and the laser line projector are machined by boring two bearing holes in the same direction, which avoids the accumulation of the turntable rotation accuracy of the equipment during the processing and ensures the concentricity of the two bearing holes.

[0038] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
