Description

Technical Field

[0001] This article relates to a welding apparatus for a box-type refrigeration system. Background Technology

[0002] Box-type refrigeration systems are widely used in workshops, large spaces, and other similar environments. Their internal components are housed within a box-shaped main frame, and welding of the internal piping must be completed within this box-like space. Traditional welding robots are limited by their reach, making it difficult to penetrate deep into the box-like space. Therefore, welding operations for this type of system currently rely heavily on manual labor.

[0003] However, with the increasing demands for welding precision and strength in industrial production, manual welding struggles to maintain consistency in specific locations and suffers from high labor intensity and low efficiency. While some existing technologies employ extendable welding devices, their instability after extension often stems from insufficient support structures, impacting welding quality. Therefore, there is an urgent need for a welding device that can penetrate deep into enclosed spaces and offers high stability. Utility Model Content

[0004] This utility model aims to provide a welding device for a box-type refrigeration system. Traditional welding robots cannot penetrate deep into the box-type refrigeration system due to insufficient extension length, and existing telescopic devices suffer from poor stability. This invention provides a welding device that can flexibly adjust the extension length and maintain stability. The specific solution is as follows:

[0005] A welding apparatus for a box-type refrigeration system includes a main body part located in the middle, auxiliary parts located on both sides of the main body part, and a prismatic column for connecting the main body part and the auxiliary parts.

[0006] Both the main body and the auxiliary body include an upper L-shaped bracket and a lower L-shaped bracket. The upper L-shaped bracket and the lower L-shaped bracket are centrally symmetrically distributed. The upper L-shaped bracket and the lower L-shaped bracket are connected by columns. The lower L-shaped bracket has a prismatic limiting hole in the middle. The prismatic column passes through the prismatic limiting hole on the auxiliary body and the main body in sequence.

[0007] The upper end of the upper L-shaped bracket of the main body is connected to the welding robot arm through a telescopic cylinder. The welding robot arm includes the robot arm body and the robot arm base.

[0008] The upper end of the upper L-shaped bracket in the auxiliary section is connected to several support columns, preferably 3, 4, or 6. Each support column has a limiting ring at its end. The limiting ring restricts the maximum distance of movement, preventing excessive elongation that could exceed the effective support length of the support column.

[0009] The support column passes through the first fixed plate and the second fixed plate in sequence, and the robot arm base is provided with a first slot and a second slot that match the first fixed plate and the second fixed plate.

[0010] To achieve precise control of the welding robot's movement, the main body of the telescopic cylinder is fixedly connected to the robot's base, while its push rod end is hinged to the upper end of the upper L-shaped bracket. This connection method allows the robot's base to be directly driven to move linearly in the vertical direction through the telescopic movement of the cylinder push rod. Simultaneously, the rigid support of the upper L-shaped bracket ensures the stability of the welding robot's trajectory during lifting and lowering, thus meeting the precise control requirements for welding positions at different depths.

[0011] To further enhance the intelligence of welding robots and achieve automatic positioning during the welding process, enabling them to adapt to multi-angle welding through rotation or small-angle movement, the welding robot includes a vision detection device mounted on its main body. This device comprises a camera and a light source, which are electrically connected to a controller located within the robot's base. The controller receives images captured by the camera and controls the movement of the robot's main body. The robot's main body also features a rotating structure, including a rotating disk and an electrically controlled rotating shaft. A wireless communication module for communicating with an external control system is mounted on the robot's base.

[0012] To further enhance the support effect, the tops of both the first and second fixing plates are tightly abutted against the lower surface of the protruding structure of the robot arm base, forming a stable support surface through surface contact. Simultaneously, reinforcing ribs are provided on the bottom side of the robot arm base, enhancing its resistance to deformation through a triangular structural mechanical design. This effectively disperses lateral stress generated during welding, ensuring the structural stability of the support system during deep-position operations.

[0013] Beneficial effects:

[0014] 1. This device can penetrate deep into the interior of a space: Through the combination of the main body and auxiliary parts, and with the extension function of the telescopic cylinder, the welding robot can penetrate deep into the interior of the box-type refrigeration system, breaking through the extension limitations of traditional robots.

[0015] 2. This device boasts high stability: The auxiliary component's fixing plate engages with the robot arm's base via slots, forming a stable support structure. Even when the robot arm is deep within the space, it effectively maintains stability, ensuring welding precision. Furthermore, the overall device employs a combination of L-shaped brackets and prismatic columns, resulting in a compact structure, minimal space occupation, and easy installation and operation within a modular space.

[0016] 3. This device is flexibly adjustable: the telescopic cylinder can flexibly adjust the extension length of the robot arm according to the depth of the chamber space to adapt to the needs of different welding positions. Attached Figure Description

Detailed Implementation

[0022] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0023] Example 1: As Figure 1-4 As shown, a welding device for a box-type refrigeration system is provided. The main structure of the welding device consists of a main body, left and right auxiliary parts, and prismatic columns 6. Both the main body and the left and right auxiliary parts are composed of an upper L-shaped bracket 5 and a lower L-shaped bracket 4. The upper and lower L-shaped brackets are centrally symmetrically distributed and vertically connected by columns to form a frame structure. A prismatic limiting hole is opened in the middle of the lower L-shaped bracket 4 for positioning in conjunction with the prismatic columns 6.

[0024] The prismatic column 6 passes through the prismatic limiting holes of the lower L-shaped bracket 4 of the left auxiliary structure 1, the main body, and the right auxiliary structure 2 in sequence, achieving a rigid connection between the three. The cross section of the prismatic column 6 matches the shape of the prismatic limiting hole 313, which can prevent the device from shifting horizontally. The two ends of the prismatic column 6 are fixed by limiting gaskets.

[0025] The bottom of the robot base 31 is fixed to the main body of the telescopic cylinder, and the end of the push rod of the telescopic cylinder is connected to the upper end of the upper L-shaped bracket 5. When the push rod of the telescopic cylinder extends or retracts, it drives the robot base 31 to move vertically, thus driving the welding robot 3 deeper into the box-shaped space.

[0026] The bottom side of the robot arm base 31 is provided with reinforcing ribs 314 to enhance structural strength. The side of the robot arm base 31 is provided with a first slot 311 and a second slot 312 for engaging with the fixing plates of the auxiliary part. The tops of the first fixing plate 11 and the second fixing plate 12 abut against the lower surface of the protruding portion of the robot arm base 31. After the ends are embedded in the first slot 311 and the second slot 312, a stable support structure is formed between the auxiliary part and the main body through the support columns. Four support columns are evenly installed on the upper L-shaped bracket 5 of the auxiliary part. The support columns penetrate the first fixing plate and the second fixing plate, and the ends are provided with limiting rings to prevent detachment.

[0027] The robot body 32 is mounted on the robot base 31 and has an internal rotating structure (rotary disk and electric rotating shaft) to adjust the welding angle.

[0028] Workflow:

[0029] S1. Place the welding device at the welding position of the box-type refrigeration system, aligning the main body with the area to be welded.

[0030] S2. Based on the depth of the box-shaped space, activate the telescopic cylinder. The push rod extends, driving the robot arm base 31 to move, allowing the welding robot arm body 32 to penetrate deeper into the box-shaped space. At the same time, the robot arm base 31 also simultaneously pushes the first and second fixed plates to move along the support column. The support column provides stable support to the robot arm base 31 through the fixed plates, ensuring that the robot arm will not shake during the welding process.

[0031] S3. Start the welding robot body 32 to perform pipeline welding operations.

[0032] S4. After welding is completed, first remove the prism column 6, then move the first fixing plate and the second fixing plate downward to disengage from the first slot 311 and the second slot 312 of the robot arm base 31, and finally retract the telescopic cylinder to return the robot arm to the initial position.

[0033] This device is specifically designed for welding operations in refrigerated box systems, offering both applicability and operational flexibility. In practical applications, the modular combination structure of the upper L-shaped bracket 5 and the lower L-shaped bracket 4 allows for maximizing the insertion depth of the welding robot arm 3 without interfering with other components, enabling it to smoothly reach the welding area inside the box space.

[0034] Compared to existing welding robots, this device can complete welding operations using only the main body in conventional welding scenarios. For welding areas with significant depth within a box-like space, the extension function of the telescopic cylinder can propel the welding robot 3 further into the space. At this point, a stable support structure is formed through the auxiliary components, utilizing the connection between the support column and the first and second fixed plates. This effectively prevents the robot base 31 from tipping over or wobbling during deep-position operations, ensuring the welding robot 3 remains highly stable throughout the welding process and providing reliable support for high-precision welding operations.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
