Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and specifically to a fixing device for welding cylinder gaskets. Background Technology

[0002] In modern manufacturing, cylinders are one of the core components of many mechanical devices (such as engines and compressors), and their performance directly affects the overall operation of the equipment. Cylinder gaskets, as sealing components at the cylinder ends, play a crucial role in preventing gas leakage and ensuring the normal operation of the cylinder. Welding is one of the important means to achieve reliable installation and sealing of cylinder gaskets. For cylinder gasket welding, to achieve ideal welding quality, it is essential to ensure that the cylinder gasket fits effectively in the predetermined position during the welding process.

[0003] However, traditional auxiliary welding tools currently have many shortcomings in the welding process of cylinder head gaskets. These traditional tools often only provide simple positioning and fixing functions and cannot fully adapt to the shape and size of the cylinder head gasket, as well as the various deformations that may occur during the welding process. For example, in some complex cylinder structures, the edges of the cylinder head gasket may be difficult to press effectively, resulting in a lack of tight contact between the gasket and the cylinder under the influence of high welding temperatures, leading to small gaps or localized warping. Moreover, traditional tools lack the flexibility to adjust when dealing with cylinder head gaskets of different thicknesses or materials, and may be unable to accurately apply the appropriate pressure, all of which adversely affect the final cylinder sealing performance.

[0004] Due to the limitations of traditional auxiliary welding tools, cylinder head gaskets cannot be effectively fitted, which significantly reduces the welding quality. Poor welding results can lead to serious problems such as gas leakage during cylinder operation, reducing equipment efficiency, shortening equipment lifespan, and increasing maintenance costs. Therefore, there is an urgent need for a cylinder head gasket welding fixing device that can effectively overcome the above problems.

[0005] In view of this, it is necessary to improve the existing cylinder head gasket welding fixing device to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figures 1 to 4 As shown, the cylinder gasket welding fixing device 100 of this utility model is used to fix the cylinder gasket 200 for welding.

[0033] The cylinder head gasket welding fixing device 100 includes two fixing components 1, a support base plate 2, and a control unit. There can be one or two support base plates 2; when two support base plates 2 are provided, each support base plate 2 supports one fixing component 1.

[0034] Two fixed components 1 are arranged opposite each other along the X direction. Each fixed component 1 includes a lifting plate 11, a lifting drive component 12, a sliding placement frame 13, a horizontal drive component 14, a first pressing component 15, and a second pressing component 16.

[0035] The upper surface of the lifting plate 11 is provided with a slide rail 111, which extends along the X direction. Specifically, in this embodiment, the upper surface of each lifting plate 11 is provided with two parallel slide rails 111 spaced apart along the Y direction.

[0036] The lifting drive component 12 is used to drive the lifting plate 11 to rise and fall. In this embodiment, the lifting drive component 12 is disposed on the support base plate 2 to connect the lifting plate 11.

[0037] Specifically, the lifting drive component 12 includes a hydraulic cylinder 121 fixed on the support base plate 2, a first connecting rod 122 connecting the hydraulic cylinder 121 and the lifting plate 11, and a telescopic rod 123 connecting the support base plate 2 and the lifting plate 11. The hydraulic cylinder 121 is used to drive the first connecting rod 122 to move up and down.

[0038] In this embodiment, each of the fixed components 1 includes two hydraulic cylinders 121 and a corresponding first connecting rod 122, as well as two telescopic rods 123. The hydraulic cylinders 121 serve as the active power to drive the lifting plate 11 to rise and fall, and the telescopic rods 123 serve as auxiliary supports.

[0039] The control unit drives the hydraulic cylinders 121 of the two fixed components 1 to work synchronously, thereby driving the two lifting plates 11 to rise and fall synchronously.

[0040] The sliding placement bracket 13 is mounted on the slide rail 111 of the lifting plate 11 and is slidably mounted relative to the slide rail 111. In this embodiment, the sliding placement brackets 13 on the two fixed components 1 can slide along the slide rail 111 to move closer or further apart. When welding is required, the two sliding placement brackets 13 move closer together, causing the cylinder gaskets 200 on the sliding placement brackets 13 to move closer together until they contact each other. Therefore, the sliding placement bracket 13 has a positioning protrusion 132 to position the cylinder gaskets 200. The cylinder gaskets 200 protrude horizontally from the sliding placement bracket 13, thus allowing welding of the cylinder gaskets 200 on both sides from below.

[0041] The sliding placement rack 13 is provided with a fixed slide plate 131, which is located on the side of the sliding placement rack 13 away from another fixed component 1 in the X direction. The fixed slide plate 131 is used to abut against the cylinder gasket 200 in the X direction.

[0042] When the cylinder gaskets 200 on the two sliding mounting brackets 13 come into contact, the two fixed sliding plates 131 support the cylinder gaskets 200 on both sides of the two cylinder gaskets 200 respectively.

[0043] The horizontal drive component 14 is connected to the sliding placement frame 13 to drive the sliding placement frame 13 to slide along the slide rail 111.

[0044] The horizontal drive component 14 includes a first electric push rod 141 disposed on the side of the sliding placement frame 13 away from the other fixed component 1 in the X direction, a second connecting rod 142 connecting the first electric push rod 141 and the sliding placement frame 13, a reinforcing frame 143 for supporting the first electric push rod 141, and a distance sensor 144 disposed on the reinforcing frame 143.

[0045] The first electric push rod 141 is used to drive the second connecting rod 142 to move in the X direction. The second connecting rod 142 is connected to the sliding placement frame 13, thereby driving the sliding placement frame 13 to slide along the slide rail 111.

[0046] The distance sensor 144 is used to detect the distance relative to the sliding shelf 13. The control unit controls the operation of the first electric push rod 141 based on the distance detected by the distance sensor 144.

[0047] The first pressing member 15 is disposed on the sliding placement frame 13 to limit the cylinder gasket 200 along the Y direction.

[0048] The first pressing member 15 includes a double-rod cylinder 151 disposed on the sliding placement frame 13, two third connecting rods 152 connected to the double-rod cylinder 151, and a first fixing plate 153 disposed at one end of the third connecting rod 152 away from the double-rod cylinder 151. The double-rod cylinder 151 is used to drive the first fixing plate 153 to move along the Y direction to clamp the cylinder gasket 200 from both sides of the Y direction.

[0049] In this embodiment, the double-rod cylinder 151 is fixedly mounted at the bottom of the sliding placement frame 13 by a support frame 154, the third connecting rod 152 is U-shaped, and the double-rod cylinder 151 can simultaneously drive the third connecting rods 152 on both sides to move relative to each other or away from each other in the Y direction.

[0050] A limiting groove 133 is formed on the fixed sliding plate 131, extending along the Y direction. A limiting block 155 is provided on the first fixed clamping plate 153, protruding into the limiting groove 133. The limiting groove 133 limits the limiting block 155, allowing the first fixed clamping plate 153 to move more stably along the Y direction. The limiting groove 133 is a blind groove, with its opening facing the fixed sliding plate 131 on the other side.

[0051] The second pressing member 16 is disposed on the sliding placement frame 13 to press the cylinder gasket 200 against the sliding placement frame 13.

[0052] The second pressing member 16 includes a second electric push rod 161 disposed on the sliding placement frame 13, a fourth connecting rod 162 connected to the second electric push rod 161, and a second fixing clamp 163 disposed on the side of the fourth connecting rod 162 away from the second electric push rod 161. The second fixing clamp 163 is located above the sliding placement frame 13. The second electric push rod 161 is used to drive the second fixing clamp 163 to move in the Z direction to press the cylinder gasket 200 from above.

[0053] In this embodiment, each of the fixing components 1 is provided with two second pressing members 16, and the two second pressing members 16 are spaced apart along the Y direction to better press the cylinder gasket 200.

[0054] In addition, in this embodiment, the first fixing plate 153 and the second fixing plate 163 are both provided with anti-slip pads on the side that contacts the cylinder gasket 200, in order to avoid slippage during pressing.

[0055] The cylinder head gasket 200 to be welded is placed on the sliding placement frame 13. The second electric push rod 161 is controlled to drive the fourth connecting rod 162 and the second fixed clamping plate 163 to descend, so that the second fixed clamping plate 163 presses the cylinder head gasket 200 tightly. Then, the double-rod cylinder 151 drives the third connecting rod 152 and the first fixed clamping plate 153 to move towards each other, so that the first fixed clamping plate 153 fixes the cylinder head gasket 200 and prevents the cylinder head gasket 200 from shaking, thereby allowing the welding joint of the cylinder head gasket 200 to fit better. Then, the first electric push rod is controlled... 141 drives the second connecting rod 142 and the sliding placement frame 13 to move inward. When the distance between the sliding placement frame 13 and the distance sensor 144 reaches the first threshold preset by the distance sensor 144, the first electric push rod 141 is controlled to stop working. At the same time, the hydraulic cylinder 121 is controlled to stop working after a certain period of time. The hydraulic cylinder 121 drives the first connecting rod 122 and the lifting plate 11 to rise to the specified height, and the telescopic rod 123 extends, so that when welding the cylinder gasket 200, the welding gun can be quickly aligned with the position of the cylinder gasket 200 to be welded.

[0056] After the cylinder gasket 200 is welded, the second electric push rod drives the fourth connecting rod 162 to raise the second fixed clamping plate 163 to the reset position, thereby releasing the second fixed clamping plate 163 from the cylinder gasket 200. Then, the double-rod cylinder 151 drives the third connecting rod 152 and the first fixed clamping plate 153 to move outward to the reset position, so that the first fixed clamping plate 153 releases the cylinder gasket 200 from the fixed position. After the cylinder gasket 200 is removed from the sliding placement frame 13, the first electric push rod 141 drives the second connecting rod 142 and the sliding placement frame 13 to move outward. When the distance between the sliding placement frame 13 and the distance sensor 144 reaches the second threshold preset by the distance sensor 144, the first electric push rod 141 stops working. At the same time, the hydraulic cylinder 121 is controlled to work in reverse for a certain period of time and then stop. The hydraulic cylinder 121 drives the first connecting rod 122 and the lifting plate 11 to descend to the reset position.

[0057] The cylinder gasket welding fixing device 100 of this utility model uses a first pressing member 15 and a second pressing member 16 to press the cylinder gasket 200 tightly, thereby preventing the cylinder gasket 200 from shaking and allowing for better fit at the welding point. A lifting drive member 12 is used to move the cylinder gasket 200 up and down to a designated position, allowing the welding gun to be quickly aligned with the welding position.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
