Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a centralized cylinder head surfacing production device. Background Art

[0002] During the cylinder head overlay welding process, the end cover to be welded is typically conveyed via a roller conveyor to a preheating furnace for heating. After preheating, a mechanical gripper places the workpiece on a welding fixture for securement. After the welding robot completes the welding process, a mechanical gripper moves the workpiece to a slow-cooling roller conveyor for slow cooling. The preheating, welding, and slow-cooling steps in this process must be performed sequentially by different equipment to ensure the quality of the cylinder head overlay welding.

[0003] However, in actual production, the preheating rollers and slow cooling rollers are usually set on both sides of the welding robot, resulting in a long material conveying path. In addition, because the production line is arranged in a straight line, the material loading and unloading stations are located at both ends of the production line, causing inconvenience in the loading and unloading process. Single operators need to frequently travel back and forth between the two ends of the production line, which increases physical exertion and reduces work efficiency. Especially on longer production lines, the traditional layout is difficult to adapt to the space limitations of certain production sites. Therefore, the existing cylinder head cladding production process has a large room for optimization in terms of material transmission path and loading and unloading efficiency, and urgently needs to be improved to improve the flexibility and work efficiency of the production line.

By arranging a jacking device on the preheating roller and the slow cooling roller, the workpiece is effectively lifted to a height suitable for grasping, so that the transfer gripper can accurately grasp and transfer the workpiece, reducing the risk of workpiece falling during the transmission process and improving the stability and reliability of material transmission. The present invention adopts a centralized transfer gripper to realize the transfer of workpieces between preheating, welding and slow cooling stations. The slow cooling roller is equipped with a heat preservation cover to ensure that the workpiece after welding will reduce the rapid loss of heat during the slow cooling process, and prevent the performance degradation of the weld due to excessive cooling speed, thereby ensuring the stability of the cylinder head welding quality and the consistency of the product. The driving component controls the precise movement of the jaws of the transfer gripper in the horizontal and vertical directions, thereby realizing the precise clamping and transfer of the workpiece, which not only improves the production efficiency, but also significantly enhances the degree of automation of the production line and reduces the complexity and labor intensity of manual operation.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1-Figure 7As shown, a centralized cylinder head surfacing production equipment includes a preheating furnace 1, a slow cooling roller 2, an automatic welding device 3 and a transfer gripper 4. The preheating furnace 1 is used to preheat the cylinder head workpiece, and a preheating roller 102 is installed on it for transferring the workpiece to be preheated. The slow cooling roller 2 is located between the preheating furnace 1 and the automatic welding equipment 3, and is used to place the workpiece after welding, and to reduce the welding stress by slowing down the cooling rate. The automatic welding equipment 3 is arranged along the arrangement direction of the preheating furnace 1 and the slow cooling roller 2, and is used for surfacing the workpiece. The transfer gripper 4 is responsible for transferring the workpiece between the preheating furnace 1, the slow cooling roller 2 and the automatic welding equipment 3 to ensure the continuity and efficiency of the production process. The transfer gripper 4 also includes a guide rail 403, a clamp 407 and a drive assembly. The drive assembly controls the movement of the clamp 407 in the horizontal and vertical directions to ensure that the workpiece can be accurately positioned and the surfacing process is completed smoothly.

[0029] In this centralized cylinder head surfacing equipment, the workpiece is first preheated by a preheating furnace 1, and the preheating roller 102 transfers the workpiece to a designated location. The transfer gripper 4, through its drive assembly, transfers the preheated workpiece to the automatic welding equipment 3 for surfacing. The workpiece after surfacing is then transferred by the transfer gripper 4 to the slow cooling roller 2. The slow cooling effect of the slow cooling roller 2 reduces welding stress and prevents thermal deformation by slowing the cooling rate of the workpiece. This implementation significantly improves the production efficiency of cylinder head surfacing and reduces quality issues caused by welding thermal stress. The continuous operation of integrated preheating, welding, and slow cooling ensures the quality of surfacing and reduces the risk of errors and workpiece damage caused by manual operation.

[0030] Preheating furnace 1 comprises a preheating furnace body 101, a preheating roller conveyor 102 that passes through the preheating furnace body 101, and hydraulic furnace doors 103 located on either side of the preheating furnace body 101. These control the opening and closing of the furnace doors when workpieces are passed in and out, ensuring a stable preheating environment. When workpieces enter the preheating furnace body 101, the hydraulic furnace doors 103 automatically open and close to maintain the thermal environment within the furnace body, ensuring a consistent preheating process. The preheating roller conveyor 102 brings workpieces in and out of the preheating zone, enabling automated heating.

[0031] The provision of the hydraulic furnace door 103 avoids heat loss, improves preheating efficiency, reduces manual operation through automatic control, and improves the consistency of the preheating process.

[0032] An insulation cover 6 is provided on the slow cooling roller 2. After welding is completed, the workpiece is placed under the insulation cover 6 through the slow cooling roller 2 to reduce direct contact with the environment, thereby achieving a slow cooling effect and ensuring a uniform reduction in the internal and surface temperature of the workpiece. The cooling speed is controlled by the insulation cover 6, which effectively reduces the stress concentration phenomenon of the workpiece during the cooling process, thereby reducing the risk of deformation caused by welding.

[0033] The discharge end of the preheating roller 102 and the loading end of the slow cooling roller 2 are both provided with a jacking device 5. The jacking device 5 lifts the workpiece at the intersection of the preheating roller 102 and the slow cooling roller 2 to ensure smooth transfer of the workpiece and reduce the risk of the workpiece falling or colliding due to the height difference between different equipment. The setting of the jacking device 5 improves the stability of the workpiece transmission process, effectively prevents damage to the workpiece during the transmission process, and improves the overall automation level of the equipment.

[0034] The jacking device 5 includes a jacking cylinder 503, a mounting frame 501, a guide 502, a jacking platform 504 and a push rod 505, wherein the output end of the jacking cylinder 503 is connected to the jacking platform 504. When the workpiece needs to be transferred to a different height position, the jacking cylinder 503 drives the jacking platform 504 and the push rod 505 to move up and down. The guide 502 ensures stability during the lifting process and realizes a smooth transition of the workpiece between different devices. The structural design of the jacking device 5 ensures the smooth transfer of the workpiece between devices, improves the overall automation performance of the production line, and reduces the need for manual operation.

[0035] The transfer gripper 4 includes a transfer frame 401, a slide 402, a guide rail 403, a mounting seat 404, a grabbing motor 405 and a bidirectional screw 406. The clamp 407 is arranged on the bidirectional screw 406, and the grabbing motor 405 drives the bidirectional screw 406 to rotate. The grabbing motor 405 drives the bidirectional screw 406 to rotate, so that the clamp 407 moves along the screw to achieve the action of clamping and releasing the workpiece. The transfer frame 401 and the slide 402 cooperate with the guide rail 403, so that the transfer gripper 4 can move flexibly along the workpiece conveying line. This design enables the transfer gripper 4 to grab and convey workpieces efficiently and accurately, improves the degree of automation of the production line, and reduces manual intervention.

[0036] The drive assembly includes a first drive assembly 408 and a second drive assembly 409. The first drive assembly 408 controls the movement of the clamp 407 in the horizontal direction, and the second drive assembly 409 controls the movement of the clamp 407 in the vertical direction. The first drive assembly 408 enables the clamp 407 to move in a horizontal position, and the second drive assembly 409 realizes lifting and lowering movement in the vertical direction, so that the clamp can grasp and place workpieces of different heights. This design realizes independent control of the transfer gripper 4 in different directions, increases the flexibility of equipment operation, and adapts it to the surfacing needs of various workpieces.

[0037] Working process: The cylinder head workpiece is first conveyed to the preheating furnace (1) via a conveyor roller. Before entering the preheating furnace (1), the workpiece passes through the preheating roller (102) and enters the preheating furnace body (101). After the workpiece is in place, the hydraulic furnace door (103) is closed, and the preheating furnace (1) starts the heating system to uniformly heat the workpiece, ensuring that the workpiece reaches the preheating temperature required for surfacing welding, thereby improving the welding quality.

[0038] After preheating is completed, the preheating roller (102) transports the workpiece to the lifting device (5) at the discharge end. The lifting cylinder (503) of the lifting device (5) is activated, pushing the lifting platform (504) and the push rod (505) to lift the workpiece to a height suitable for the transfer gripper (4) to grasp it. At this time, the clamping claw (407) of the transfer gripper (4) is positioned to the preheating process under the control of the drive assembly (408, 409), accurately clamping the workpiece and lifting it to the position of the automatic welding equipment (3).

[0039] At the automatic welding equipment (3), the transfer gripper (4) places the workpiece on the welding fixture for fixation, and the automatic welding equipment (3) starts the welding operation. The welding robot performs overlay welding on the workpiece according to the preset welding path to ensure the uniformity and stability of the welding layer. After welding is completed, the transfer gripper (4) grabs the welded workpiece again and transfers it to the loading end of the slow cooling roller (2).

[0040] The welded workpiece is placed on a slow cooling roller (2). The slow cooling roller (2) is equipped with a heat preservation cover (6) for covering the outside of the workpiece to slow down its cooling speed. The slow cooling roller (2) slowly conveys the workpiece so that the stability of the weld performance is maintained during the slow cooling process, thereby preventing the welding part from being affected by rapid cooling and affecting the welding quality.

[0041] After the slow cooling process is completed, the slow cooling roller (2) transfers the workpiece to the jacking device (5), which lifts the workpiece again to facilitate the operator or transfer equipment to unload the workpiece. The entire cladding production process of the workpiece is now completed.

[0042] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
