Technical Field

[0001] This utility model relates to the field of tooling technology for production, and in particular to an assembly structure for a gas storage tank head. Background Technology

[0002] Figure 1 An air receiver tank is an essential component of a stationary screw air compressor. It effectively stabilizes the air pressure delivered to the air-consuming equipment, reduces the moisture content and heat of the gas at the equipment end, and effectively protects the equipment. While stabilizing the air pressure, it also reduces the frequency of loading and unloading the air compressor, thus extending its service life to some extent.

[0003] The gas storage tank has a cylindrical shape with approximately elliptical end caps at both ends. Currently, during assembly, welding requires first welding lifting plates onto the end caps, then lifting and adjusting the end caps close to the gas storage tank body, tapping for initial positioning, and then rotating and tapping again. This process is cumbersome and highly dangerous. Utility Model Content

[0004] The purpose of this utility model is to provide an assembly structure for gas storage tank heads, so as to solve the complex operation process of spot welding using welding lifting plates in the existing assembly process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gas storage tank end cap assembly structure includes a base frame. A set of identical support seats I and support seats II are arranged opposite each other on the base frame. Support seat I is fixedly installed at one end of the base frame, and the bottom of support seat II is slidably disposed at the other end of the base frame. A lateral positioning mechanism for driving support seat II to slide is provided on the base frame.

[0007] Both support base I and support base II are equipped with longitudinal positioning mechanisms, and a support component is provided on the base frame, which is located between support base I and support base II.

[0008] As a further embodiment of this utility model, the longitudinal positioning mechanism includes a first cylinder and a clamping block I. The first cylinder is disposed on the top of the support base, and a clamping block II with the same structure as the clamping block I is disposed on the support base corresponding to the clamping block I.

[0009] As a further embodiment of this utility model, the top of the clamping block I is provided with a guide shaft, the upper end of which slides through the top of the support base.

[0010] As a further embodiment of this utility model, the clamping block is V-shaped, and the top of the clamping block is provided with a head clamping part and an inclined tank guide part.

[0011] As a further embodiment of this utility model, the lateral positioning mechanism includes a second cylinder and a fixed seat. The fixed seat is fixedly installed on the outer end of the support seat II on the base frame. The second cylinder is height-adjustable and is mounted on the fixed seat via an assembly seat. A connecting plate is provided through the piston rod end of the second cylinder, and the connecting plate abuts against the outer side of the support seat II.

[0012] As a further embodiment of this utility model, a set of symmetrical adjustment holes are longitudinally provided on the fixed base, the second cylinder is fixedly installed on the mounting base, and an adjustment screw is provided on the top of the mounting base. The upper end of the adjustment screw slides through the perforated plate located on the top of the fixed base.

[0013] As a further embodiment of this utility model, the support base is provided with longitudinally spaced limiting holes, and a positioning pin is slidably arranged in each limiting hole. The positioning pin near the transverse positioning mechanism passes through the support base II and connects to the end of the second cylinder.

[0014] As a further preferred embodiment of this utility model, the support member includes a bearing plate, which is mounted on a base frame. A set of mounting seats is provided at the front and rear of the top of the bearing plate, and each mounting seat is rotatably equipped with a non-powered roller.

[0015] Compared with the prior art, the gas tank end cap assembly structure provided by this utility model has the following beneficial effects: This utility model achieves precise docking between the tank body and the end cap through the longitudinal positioning mechanism and the transverse positioning mechanism in conjunction with the support seat.

They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0032] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present invention should be understood according to the specific circumstances.

[0033] See Figure 2-4 As shown in the figure, an embodiment of the present invention provides a gas storage tank end cap assembly structure, including a base frame 2. The base frame 2 is provided with a support seat I 31 and a support seat II 32, which are arranged opposite each other with identical structures. The support seat I 31 is fixedly installed at one end of the base frame 2. The bottom of the support seat II 32 is provided with a slider 302. The base frame 2 is provided with a slide rail 301, and the slider 302 is slidably installed on the slide rail 301. The base frame 2 is provided with a transverse positioning mechanism 5 for driving the support seat II 32 to slide. Both the support seat I 31 and the support seat II 32 are provided with a longitudinal positioning mechanism 4 for clamping the end cap 101. The base frame 2 is provided with a support member 6 for supporting the tank body 1, which is disposed between the support seat I 31 and the support seat II 32.

[0034] In the above technical solution, the base frame 2 provides a stable support foundation for the entire assembly structure. The fixed support seat I 31 serves as a reference point, and the slidable support seat II 32 slides on the slide rail 301 via the slider 302. The lateral positioning mechanism 5 drives the support seat II 32 to move, thereby adjusting the distance between the support seat I 31 and the support seat II 32 according to the length of the tank body 1 to accommodate the assembly of gas storage tanks of different specifications. The longitudinal positioning mechanism 4 is used to fix the end cap 101, and the support member 6 supports the tank body 1, so that the tank body 1 and the end cap 101 are in a suitable assembly position.

[0035] See Figure 3 , 4 As shown, the longitudinal positioning mechanism 4 includes a first cylinder 401 and a clamping block I 402. The first cylinder 401 is disposed on the top of the support base. A clamping block II with the same structure as the clamping block I 402 is disposed opposite to the support base on the clamping block I 402. The clamping block I 402 is fixedly disposed at the bottom of the piston rod of the first cylinder 401, and the clamping block II is fixedly disposed on the support base.

[0036] In use, the piston rod of the first cylinder 401 extends and retracts, causing the upper clamping block I 402 to move up and down. When the piston rod extends, the upper clamping block I 402 moves down and cooperates with the lower clamping block II to clamp the end cap 101 between the clamping block I 402 and the clamping block II, thereby achieving the longitudinal positioning of the end cap 101.

[0037] The clamping block I 402 located at the top is provided with a guide shaft 403, the upper end of which slides through the top of the support base. The guide shaft 403 slides within a sliding hole at the top of the support base, providing guidance for the up-and-down movement of the clamping block I 402, ensuring the stability and accuracy of the clamping block I 402 during movement, preventing the clamping block I 402 from shifting during movement, and thus clamping the end cap 101 more precisely.

[0038] See Figure 5As shown, clamping block I 402 and clamping block II, which have the same structure, are both V-shaped. Each clamping block has a head clamping part 4021 and an inclined tank guide part 4022 on its top. The V-shaped clamping block better fits the head 101, improving clamping stability. The head clamping part 4021 is used to directly clamp the head 101, while the inclined tank guide part 4022 guides the tank 1 to accurately enter the assembly position when it approaches the head 101 for assembly, making the connection between the tank 1 and the head 101 smoother.

[0039] See Figure 3 As shown, the lateral positioning mechanism 5 includes a second cylinder 501 and a fixed base 502. The fixed base 502 is fixedly mounted on the base frame 2. The second cylinder 501 is height-adjustable and mounted on the fixed base 502 at the outer end of the support seat II 32. A connecting plate 504 passes through the piston rod end of the second cylinder 501 and abuts against the outside of the support seat II 32. When the piston rod of the second cylinder 501 extends or retracts, it drives the slidable support seat II 32 to move on the slide rail 301 through the connecting plate 504. The height of the second cylinder 501 is adjustable, and its height can be adjusted according to assembly requirements to adapt to end caps 101 of different sizes, thereby achieving accurate docking of the tank body 1 and the end cap 101 in the lateral direction.

[0040] A set of symmetrical adjustment holes 503 are longitudinally formed on the fixed base 502. An adjustment screw 506 is provided on the top of the mounting base 505. The upper end of the adjustment screw 506 slides through the perforated plate 507 located on the top of the fixed base 502, and the lower end of the adjustment screw 506 abuts against the upper end of the mounting base 505 and is locked with a nut. In use, the nut at the lower end of the adjustment screw 506 is loosened, and the mounting base 505 can be adjusted in position within the adjustment holes 503. Rotating the perforated plate 507 will cause the adjustment screw 506 to move up and down relative to the fixed base 502, thereby driving the mounting base 505 and the second cylinder 501 to move up and down. After adjusting to a suitable height, the nut is tightened to fix the second cylinder 501 at the appropriate height position.

[0041] Both support base I 31 and support base II 32 have longitudinally opened limiting waist holes 303. A positioning pin 7 is slidably installed in both limiting waist holes 303. The positioning pin 7 near the transverse positioning mechanism 5 passes through support base II 32 and connects to the second cylinder 501. The positioning pin 7 can be inserted into the positioning hole 1011 of the end cap 101 to provide transverse positioning and guidance for the end cap 101, further ensuring the accurate docking of the tank body 1 and the end cap 101.

[0042] See Figure 3As shown, the support member 6 includes a bearing plate 601, which is mounted on the base frame 2. A set of mounting seats 602 are fixedly installed at the front and rear of the top of the support member 6, and each mounting seat 602 is rotatably connected to a non-powered roller 603. The non-powered roller 603 is rotatably connected to the top of the support member 6 through the mounting seats 602. When the tank 1 is placed on the non-powered roller 603, the non-powered roller 603 can rotate with the movement of the tank 1, reducing the friction between the tank 1 and the support member 6, facilitating the placement and adjustment of the tank 1, and also providing support for the tank 1.

[0043] In this embodiment of the invention, the end cap 101 is placed on the lower clamping block II on the support base I 31 and support base II 32. The first cylinder 401 is activated, causing the upper clamping block I 402 to move downward, clamping the end cap 101 through the end cap clamping part 4021. The tank body 1 is hoisted onto the unpowered roller 603 of the support member 6, and the piston rod of the second cylinder 501 extends and drives the slidable support base II 32 to move along the slide rail 301 towards the fixed support base I 31 via the connecting plate 504.

[0044] Driven by the second cylinder 501 and guided by the tank guide part 4022, the tank body 1 and the end cap 101 are effectively fitted together; at the same time, one end of the positioning pin 7 is inserted into the positioning hole 1011 of the end cap 101, which can further improve the stability during welding.

[0045] During welding, the connection between the tank body 1 and the end cap 101 is welded with positioning welds. The first cylinder 401 and the transverse positioning mechanism 5 are loosened, the tank body 1 is rotated, and the remaining welds are welded to complete the assembly of the gas storage tank end cap.

[0046] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
