Description

Technical Field

[0001] This utility model relates to the field of laser cleaning technology, specifically to an adjustable-angle auxiliary device for a laser cleaning gun. Background Technology

[0002] When using a laser cleaning machine to remove rust and paint from workpieces, it is usually necessary to control the distance between the workpiece surface and the focusing lens of the output laser to ensure that the output laser is focused on the workpiece surface and has sufficient energy to vaporize the paint or rust. This is especially important when using a handheld laser head, as the user cannot precisely control the working height. Changes in height can lead to uneven rust removal and an inability to control the laser's focal point, affecting work efficiency and quality. Therefore, it is necessary to...

[0003] Laser cleaning can be performed using auxiliary devices to improve the quality and efficiency of the work. For example, Chinese patent CN210497492U discloses an angle-adjustable auxiliary device for a laser cleaning gun, which enables the adjustment of the angle of the laser cleaning gun and solves the problem of the laser cleaning gun not being able to change direction according to the position of the workpiece, resulting in inconsistency in its use.

[0004] However, it is not universally applicable to cleaning power grid equipment. The reason is that power grid equipment often has small gaps after installation, and the auxiliary device disclosed in CN210497492U cannot enter these small gaps to thoroughly clean the equipment. Therefore, further improvements have been made to an adjustable-angle auxiliary device for a laser cleaning gun. Utility Model Content

[0031] 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.

[0032] like Figure 1 As shown, this utility model provides a technical solution: an adjustable angle auxiliary device for a laser cleaning gun, including a U-shaped bracket 1 and a laser cleaning gun body 2. The U-shaped bracket 1 is connected to a support column 4 via a rotating arm 3, and the lower end of the support column 4 is fixedly connected to a base 5.

[0033] The rotating arm 3 includes a first slewing bearing 31, a first support arm 32, a second slewing bearing 33, a second support arm 34, a third slewing bearing 35, a vertical arm 36, and a fourth slewing bearing 37.

[0034] The U-shaped bracket 1 is connected to the first support arm 32 via a first slewing bearing 31, and the U-shaped bracket 1 rotates axially relative to the first support arm 32 via the first slewing bearing 31; the first support arm 32 is connected to the second support arm 34 via a second slewing bearing 33, and the first support arm 32 rotates with the second support arm 34 via the second slewing bearing 33; the second support arm 34 is connected to the upright arm 36 via a third slewing bearing 35, and the second support arm 34 rotates with the upright arm 36 via the third slewing bearing 35; the upright arm 36 is connected to the top of the support column 4 via a fourth slewing bearing 37.

[0035] The bottom end of the boom 36 and the top end of the support column 4 are respectively bolted to both sides of the fourth slewing bearing 37.

[0036] The inner wall of the U-shaped bracket 1 is provided with two symmetrical connecting rods 6, namely the first connecting rod 61 and the second connecting rod 62. The opposite ends of the two connecting rods 6 are fixedly connected with connectors 7. The other end of the second connecting rod 62 is provided with a locking device 8. The inside of the connector 7 is a cavity 9, which is an open structure. A roller 10 is slidably installed in the cavity 9. The outer wall of the laser cleaning gun body 2 is provided with a slot 11, and the roller 10 is locked in the slot 11. The slot 11 on the outer wall of the laser cleaning gun body 2 is a hemispherical slot to allow the laser cleaning gun body 2 to rotate freely.

[0037] The second connecting rod 62 extends to the outside of the U-shaped bracket 1 through the through hole 12 provided on the U-shaped bracket 1, and the locking device 8 is located on the outside of the U-shaped bracket 1.

[0038] Specifically, the first connecting rod 61 is fixedly connected to the inner wall of the U-shaped bracket 1. During installation, the second connecting rod 62 is first inserted into the through hole 12. The connector 7 at the end of the second connecting rod 62 abuts against the inner wall of the U-shaped bracket 1, thereby achieving a relative fixation of the distance between the connectors 7 at the ends of the first connecting rod 61 and the second connecting rod 62, so as to achieve the function of relatively locking the laser cleaning gun body 2.

[0039] like Figure 2 As shown, both ends of the first support arm 32 and the second support arm 34 are provided with connecting flanges 38.

[0040] Specifically, a first connecting flange 38.1 is vertically installed at one end of the first support arm 32. The first connecting flange 38.1 is bolted to one side of the first slewing bearing 31, and the other side of the first slewing bearing 31 is bolted to the U-shaped bracket 1. The other end of the first support arm 32 is vertically fixedly connected to the first crossbar 32.1. The two ends of the first crossbar 32.1 are respectively vertically installed with second connecting flanges 38.2. The two second connecting flanges 38.2 are respectively bolted to one side of a second slewing bearing 33.

[0041] Two third connecting flanges 38.3 are symmetrically spaced at one end of the second support arm 34. The third connecting flanges 38.3 are fixedly connected to the end of the second support arm 34 via the second crossbar 34.1. The third connecting flanges 38.3 and the second crossbar 34.1 form a U-shaped structure. The third connecting flanges 38.3 are bolted to the other side of the second slewing bearing 33.

[0042] The other end of the second arm 34 is vertically fixedly connected to the third crossbar 34.2. The two ends of the third crossbar 34.2 are respectively vertically provided with fourth connecting flanges 38.4. The two fourth connecting flanges 38.4 are respectively connected to one side of a third slewing bearing 35 by bolts.

[0043] The top of the boom 36 is a U-shaped opening 361. Screw holes are provided on both sides of the U-shaped opening 361, which are connected to the other side of a third slewing bearing 35 by bolts.

[0044] like Figure 3 As shown, the locking device 8 includes a limiting block 81 that is slidably sleeved on the second connecting rod 62. The outer side wall of the U-shaped bracket 1 is provided with a limiting groove 82 that matches the limiting block 81. A handle 83 is fixedly connected to the outer end of the limiting block 81. A sliding rod 84 is fixedly connected to the end of the second connecting rod 62. The handle 83 is hollow inside. A sliding groove 85 that matches the sliding rod 84 is opened on the inner side wall of the handle 83. A first spring 86 is sleeved on the outer side wall of the second connecting rod 62, and the first spring 86 is located between the sliding rod 84 and the limiting block 81.

[0045] Specifically, the limiting block 81 is slidably sleeved on the second connecting rod 62. The outer wall of the U-shaped bracket 1 is provided with a limiting groove 82 that matches the limiting block 81. When the limiting block 81 is engaged in the limiting groove 82 under the action of the first spring 86, because the handle 83 is fixedly connected to the limiting block 81, the sliding rod 84 located in the handle 83 and sliding along the sliding groove 85 is fixedly connected to the second connecting rod 62, thereby realizing the restriction of the rotation of the second connecting rod 62.

[0046] like Figure 4-5 As shown, the inner wall of the cavity 9 has two symmetrical strip-shaped openings 91. A sliding slip ring 92 is provided in the strip-shaped opening 91, and a second spring 93 is connected to the slip ring 92 at one end and to the end of the strip-shaped opening 91 at the other end. The shaft of the roller 10 is inserted into the slip ring 92.

[0047] The inner wall of the cavity 9 has two symmetrical strip-shaped openings 91. A slip ring 92 is slidably connected inside the strip-shaped opening 91. The rotating shaft of the roller 10 is inserted into the slip ring 92. A second spring 93 is fixedly connected between the slip ring 92 and the strip-shaped opening 91. When the laser cleaning gun body 2 is inserted into the connector 7, the surface of the laser cleaning gun body 2 contacts the roller 10. The laser cleaning gun body 2 pushes the roller 10 to slide inside the cavity 9. The roller 10 drives the slip ring 92 to slide inside the strip-shaped opening 91. The second spring 93 is compressed. When the connector 7 reaches the slot 11 on the laser cleaning gun body 2, the roller 10 enters the slot 11. Due to the elastic force of the second spring 93, the roller 10 is stuck in the slot 11.

[0048] In another embodiment, in order to better lock the laser cleaning gun body 2 and prevent the laser cleaning gun body 2 from compressing the second spring 93, thereby causing the roller 10 to fall out of the slot 11, a limiting pin 621 is provided on the second connecting rod 62 located in the inner wall of the U-shaped bracket 1.

[0049] Specifically, the second connecting rod 62 is provided with several pin holes so as to adjust the length of the second connecting rod 62 inside the U-shaped bracket 1 by means of the limiting pin 621.

[0050] The outer wall of the connector 7 has an opening groove 71, which is provided to facilitate the connection of the connecting pipe connected to the laser cleaning gun body 2 to disengage from the connector 7.

[0051] The slewing bearing is either an external gear slewing bearing or an internal gear slewing bearing, driven by a servo motor. The servo motor is mounted on or inside the support arm and connected to the slewing bearing via a drive rod. The installation space is reserved according to the actual size of the equipment, and all of these are existing technologies, so they will not be described in detail.

[0052] The beneficial effects of this utility model are: an adjustable auxiliary device for laser cleaning guns, which achieves free adjustment of the entire angle through a rotating arm, with the rotating arm rotating around the support column and at the top of the support column, making the rotation more flexible.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
