Technical Field

[0001] This utility model relates to the technical field of welding auxiliary devices, specifically a welding auxiliary device for hydraulic machinery production. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to hydraulic machinery is also constantly improving. Hydraulic machinery is a device that works by using fluid energy. Hydraulic machinery is assembled from many components and requires many processing steps during the production process, including welding.

[0003] A search revealed that this utility model relates to a welding auxiliary device, specifically a pipe welding auxiliary device, with authorized Chinese patent document number CN 216780750 U. This utility model provides a simple, easy-to-use, and accurate pipe welding auxiliary device that effectively improves welding efficiency. The device includes: a first locking block with a first support rod at its top and a groove in its middle; a connecting rod with a connecting rod at its upper end; a screw with a threaded hole at the top center of the connecting rod, into which the screw is rotatably mounted; a handle at the top of the screw; and a slider at the bottom of the screw. Turning the handle downwards moves the screw downwards, causing the slider to move downwards, which in turn moves the locking rods at both ends of the slider downwards, pulling the second support rod on the right side inwards and causing the second locking block to move to the left.

[0004] The welding auxiliary device in the above patent still has some shortcomings. In the production of hydraulic machinery, the rigid pipes used to transmit high-pressure oil in the hydraulic system need to be connected by welding between pipes and between pipes and joints. However, most of the existing auxiliary mechanisms for pipe head welding have simple structures and are difficult to adjust the welding position of the pipe head, which brings some trouble to the welding of the pipe head. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a welding auxiliary device for hydraulic machinery production, which solves the problem that most existing auxiliary mechanisms for pipe head welding have simple structures and are difficult to adjust the welding position of the pipe head, thus causing certain troubles for the welding of the pipe head.

[0018] Please see Figure 1-4 , Example 1: A welding auxiliary device for hydraulic machinery production includes a bottom support plate 1, a pipe support assembly 2 is provided at the top end of the bottom support plate 1, a pipe head adjustment assembly 3 is provided at the top of the bottom support plate 1, a connecting pipe 4 is provided on the pipe support assembly 2, and a connecting pipe head 5 is provided on the pipe head adjustment assembly 3.

[0019] The pipe support assembly 2 includes a limiting support plate 201 fixed to the top side of the bottom support plate 1. Two retraction grooves 202 are symmetrically opened on the inner wall of the end of the limiting support plate 201. Each retraction groove 202 is provided with an abutting push plate 203. An abutting screw 204 is vertically rotatably provided on the side of the abutting push plate 203. The end of the abutting screw 204 rotatably passes through the retraction groove 202.

[0020] The pipe head adjustment assembly 3 includes an adjustment support frame 301 set on the top of the bottom support plate 1. Two limiting grooves 302 are symmetrically opened at the top of the bottom support plate 1. Two limiting sliders 303 are symmetrically fixed on both sides of the bottom end of the adjustment support frame 301. The limiting sliders 303 are slidably inserted into the limiting grooves 302. Side limiting plates 304 are fixed on the side of the top of the limiting grooves 302. Limiting slots 305 are opened in the side limiting plates 304. Two locking screws 306 are symmetrically and vertically arranged at the bottom ends of both sides of the adjustment support frame 301. The ends of the locking screws 306 pass through the limiting slots 305. Locking nuts 307 are sleeved on the ends of the locking screws 306. A top side placement cavity 308 is provided on the top of the adjustment support frame 301.

[0021] A bottom adjustment cavity 309 is provided on the bottom side of the top placement cavity 308. A lifting support plate 310 is provided at the bottom of the top placement cavity 308. An adjustment screw 311 is vertically rotatably connected to the bottom end of the lifting support plate 310. The bottom end of the adjustment screw 311 extends through the adjustment support frame 301 into the bottom adjustment cavity 309. A top connecting plate 312 is provided on the top of the adjustment support frame 301. A stable abutment plate 313 is fixed at the bottom end of the top connecting plate 312. Connection holes 314 are evenly opened around the top of the top connecting plate 312. Two connecting studs 315 are symmetrically arranged on both sides of the top of the adjustment support frame 301. The connecting studs 315 pass through the connection holes 314. A connecting nut 316 is sleeved on the top of the connecting studs 315.

[0022] Example 2: The difference between this example and Example 1 is that the top side of the limiting support plate 201 is curved in an arc shape, and the connecting pipe 4 is placed on the top of the limiting support plate 201.

[0023] This makes the support plate 201 more stable for the connecting pipe 4.

[0024] Example 3: The difference between this example and Example 1 is that the bottom end of the adjusting screw 311 is provided with a throttle handle.

[0025] This makes it more convenient for users to rotate the adjusting screw 311.

[0026] Example 4: The difference between this example and Example 1 is that the bottom side of the stabilizing contact plate 313 is curved in an arc shape.

[0027] This allows the stable contact plate 313 to fit more closely against the top side of the connecting pipe 4.

[0028] In this embodiment, since most of the existing auxiliary mechanisms for pipe welding have simple structures, it is difficult to adjust the welding position of the pipe head, which brings certain troubles to the pipe welding.

[0029] In summary, in practical implementation, when the user needs to weld the connecting pipe 4 and the connecting pipe head 5 together, the user first needs to place the connecting pipe 4 on the pipe support assembly 2. The bottom of the connecting pipe 4 is supported by the limiting support plate 201, while the abutting push plate 203 gradually abuts against both sides of the end of the connecting pipe 4 under the push of the abutting screw 204, ensuring that the end of the connecting pipe 4 to be welded can be kept stable by the clamping of the abutting push plate 203.

[0030] Next, after placing the connecting pipe head 5 in the pipe head adjustment assembly 3, the user can adjust the bottom height of the connecting pipe head 5 placed in the top side placement cavity 308 by rotating the adjusting screw 311. Rotating the adjusting screw 311 will push the lifting support plate 310 to move upward, thereby raising the connecting pipe head 5 placed in the top side placement cavity 308 so that its end is on the same horizontal plane as the end of the connecting pipe 4, so as to facilitate subsequent welding operations.

[0031] Once the connecting pipe head 5 is raised to the welding height, the user can slide the top connecting plate 312 into the connecting stud 315 through the connecting hole 314 to adjust the contact height between the bottom stable contact plate 313 of the top connecting plate 312 and the top side of the connecting pipe head 5. This ensures that the stable contact plate 313 can fit against the top side of the connecting pipe head 5, maintaining the stability of the connecting pipe head 5 in the top side placement cavity 308. The bottom end of the adjusting support frame 301 slides in the limiting slide groove 302 through the set limiting slider 303, allowing for back-and-forth sliding adjustment. The locking screw 306 slides in the limiting slide groove 305. By fitting a locking nut 307 onto the end of the locking screw 306, the adjusting support frame 301, after being moved to the welding position, can be fixedly connected to the bottom support plate 1 to maintain its stability and facilitate subsequent welding operations.
