Description

Technical Field

[0001] This utility model belongs to the technical field of laser filter protection boxes, specifically, it relates to a welding machine filter observation protection box. Background Technology

[0002] With the development of various laser welding machines towards high power, portability and economy, laser welding machines, due to their highly concentrated energy and small heat-affected zone, meet the technical development direction of high quality, low consumption, high efficiency, cleanliness, narrow heat-affected zone, small joint deformation and flexible operation. In addition, laser beams have the advantage of being able to weld in the atmosphere, which can perform deep penetration welding on large components and precision welding on micro parts. However, the strong light emitted by welding can hurt people's eyes and make it impossible for people to observe and study. Therefore, there is a need for an observation filter protection box with a light filtering function.

[0003] For example, a patent entitled "A Laser Welding Machine Filter Observation and Protection Box" (patent application number: CN202223027661.2) discloses a laser welding machine filter observation and protection box. The box has holes at both ends on one side of the bottom. A protective glove is placed inside the box on one side of the hole. The operator's arm is inserted into the box through the hole to perform the welding procedure. The position of the hole is fixed, which limits the operator's arm operation. In addition, different people have different arm sizes, so it is not easy to adapt to different people.

[0004] Therefore, it is necessary to propose a welding machine filter observation and protection box to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a welding machine filter observation protective box. This solves the problem that in existing technologies, personnel have to insert their hands through holes into the protective box to perform welding procedures. The positions of these holes are fixed, which limits the operation of personnel's arms. Furthermore, different personnel have different arm sizes, making it difficult to adapt to different individuals.

[0006] The present invention adopts the following technical solution.

[0007] A protective box for filtering and observing welding machines includes a protective box body. An operating door is provided on one side of the protective box body. A through groove is provided on the operating door. A first sliding groove and a second sliding groove are provided along the length direction at the top of the operating door. The first sliding groove and the second sliding groove are arranged parallel to each other. Sliding plates are slidably fitted inside the first sliding groove and the second sliding groove. Hand operation holes are provided on both sliding plates. Both hand operation holes are connected to the interior of the protective box body.

[0008] Preferably, both ends of the through groove near the center of the protective box are fixed with inner plates, and two sliding plates are used to cover the through groove.

[0009] Preferably, a fixing plate is fixed to the bottom of the protective box, a groove is provided at the top of the fixing plate, and a collection box is fixed to the bottom of the fixing plate.

[0010] Preferably, the four inner walls of the groove are provided with adsorption slots, the four adsorption slots are connected to the collection box, and the bottom of the collection box is connected to a suction pump through a pipe.

[0011] Preferably, a supporting base plate is provided below the fixing plate, and electric push rods are fixed at the four corners of the top of the supporting base plate, and the four corners of the bottom of the fixing plate are fixed to the top of the electric push rods.

[0012] Preferably, the suction pump is fixed to the support base plate, and the outer sides of the two electric push rods located on the same side are provided with protective shells.

[0013] Preferably, each of the four corners of the bottom of the support base plate is provided with a movable wheel.

[0014] Preferably, the top of the protective enclosure is provided with a top cover, and a fan is embedded in the top cover, with the air outlet of the fan facing the interior of the protective enclosure.

[0015] Preferably, an auxiliary handle is fixed to one side of the protective housing.

[0016] The beneficial effects of this utility model are as follows, compared with the prior art:

[0017] 1. In the actual operation of this utility model, personnel can insert their two hands into the interior of the protective box through the two hand operation holes to perform welding. At the same time, as needed, the two sliding plates can slide in the first sliding groove and the second sliding groove respectively, changing the distance between the two hand operation holes to adapt to different operational needs. During actual welding, the hands are more flexible. Compared with fixed hand operation holes, sliding hand operation holes will not obstruct the movement of the personnel's arms. Furthermore, the two sliding plates can be slid to the same side to open the protective box, thereby facilitating the handling of welding items.

[0018] 2. In the actual operation of this utility model, during welding, a suction pump can be started. The suction force generated by the suction pump can draw the welding debris into the collection box through the adsorption tank. The wind force generated by the fan can accelerate the collection of debris. At the same time, after welding is completed, the fan can also cool the welded items to prevent the welding area from getting too hot and causing injury to the hands of the personnel handling it.
