Description

Technical Field

[0001] This invention relates to the field of air compressor housing welding technology, specifically to an air compressor housing welding device. Background Technology

[0002] A compressor is a machine that can compress gas or vapor into high-pressure gas or vapor. Its internal structure is relatively complex, including components such as compressor head, cylinder, piston, cylinder head, valves and connecting pipes. In order to protect these components from external damage and contamination, compressors are generally designed with an outer casing. Therefore, the main functions of the compressor casing include providing structural support, achieving sealing, and protecting internal components.

[0003] Currently, the air compressor casing is exposed to the environment for extended periods. Due to the influence of the operating environment, humidity and corrosive factors can cause corrosion to the air compressor casing. In particular, the corrosion rate will accelerate after the paint layer on the casing surface is peeled off due to external impact. In severe cases, it can cause damage to the joints of the main pipe section and the cover. However, during the maintenance of the cover and the main pipe section, the existing welding equipment has calibration errors between the cover and the main pipe section. Therefore, the integrity and sealing of the joint after welding will be greatly affected.

[0004] In view of this, an air compressor housing welding device was designed to solve the above problems. Summary of the Invention

A buckle plate is installed at the outer end of two adjacent trusses, and a double-ended screw is threaded on the buckle plate. A soft pad is inserted into the inner end of the double-ended screw.

[0010] In a preferred embodiment, the present invention can be further configured as follows: a slide rail is provided inside the truss, a compression spring is fixedly installed on the plate surface inserted into the slide rail, and a second guide rod is movably installed inside the slide rail, while the other end of the compression spring is fixedly installed on the second guide rod, a second clamp is installed on the inner end of the second guide rod, and a second bolt is installed in the second guide rod and the second clamp.

[0011] In a preferred embodiment, the present invention can be further configured such that: both the first clamp and the second clamp have an arc-shaped structure, and the inner walls of the first clamp and the second clamp are provided with anti-slip pads.

[0018] 3. This invention uses two sets of second clamps to clamp and fix the two caps, and uses two bidirectional screws to push the two caps. Finally, the two caps are effectively pressed and fixed on the two ends of the main pipe section.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of an air compressor housing welding device provided by the present invention. Example 1:

[0024] Combination Figures 1 to 7 As shown, the present invention provides an air compressor housing welding device, including an air compressor housing 200, a calibration clamping mechanism 100 for clamping the air compressor housing 200, and a housing angle adjustment mechanism 300 installed on the calibration clamping mechanism 100. The calibration clamping mechanism 100 is used to enhance the fixation of the horizontally positioned calibration clamping mechanism 100 and improve the welding accuracy of the horizontally positioned calibration clamping mechanism 100. The housing angle adjustment mechanism 300 is used to enhance the stability of the clamping of the calibration clamping mechanism 100 and improve the strength of the welding interface of the calibration clamping mechanism 100.

[0025] The calibration clamping mechanism 100 includes a support frame 110, inside which a crossbeam 160 is installed. Two sets of clamps 1101 are fixedly installed on the crossbeam of the support frame 110. Two slides 170 are movably installed on the crossbeam 160. A stud 1701 is installed at the bottom of the slide 170. A positioning plate 1702 is installed on the stud on the back of the slide 170. A first guide rod 180 is installed inside the positioning plate 1702. A first clamp is installed at the inner end of the first guide rod 180. 1801, a first bolt 1802 is installed in the first guide rod 180 and the first clamp 1801. A traction plate 1504 is movably installed on the column head 1701. A clamp 1503 is installed at the bottom end of the traction plate 1504. A traction frame 1502 is movably installed on the clamp 1503. An end plate 1501 is movably installed at the other end of the traction frame 1502. A hydraulic component 150 is installed in the end plate 1501. The hydraulic component 150 is fixedly installed in the two sets of clamps 1101. Two support rods 120 are fixedly installed on the top of the support frame 110. A horizontally placed smoke pipe 130 is fixedly installed on the two support rods 120. Two symmetrically distributed guide hoods 1302 are fixedly installed at both ends of the smoke pipe 130. A smoke exhaust chamber 1301 communicating with the inner cavity of the two guide hoods 1302 is opened inside the smoke pipe 130. Two symmetrically distributed fixing plates 1602 are fixedly installed at both ends of the crossbeam 160. A stabilizing bracket 1603 is movably installed on the fixing plate 1602, and the other end of the stabilizing bracket 1603 is movably installed on the slide block 170. Two springs 1601 are provided between two adjacent slides 170, and the two springs 1601 are located on the outside of the crossbeam 160; The support frame 110 has a U-shaped structure at both ends, and the plate ends of the support frame 110 that are in contact with the ground at both ends are provided with elliptical insertion holes to enhance the stability of the support frame 110 after it is in contact with the ground. An exhaust pipe 140 is fixedly installed at the bottom of the smoke pipe 130, and the exhaust pipe 140 is adapted to connect to the smoke exhaust chamber 1301, so as to facilitate the extraction of smoke generated by the joint of the calibration clamping mechanism 100. The air compressor housing 200 is clamped within two adjacent first clamps 1801.

[0026] In use, the hydraulic component 150 is pre-operated. As the hydraulic rod inside the hydraulic component 150 extends outward, the end plate 1501 fixed to the outer end of the hydraulic rod will drive the traction frame 1502 to extend. The extended traction frame 1502 will pull the clamp 1503 upward. Finally, the clamp 1503 will drive the two traction plates 1504 to open outward simultaneously. The two traction plates 1504 that open outward simultaneously push the two column heads 1701 and the two slides 170 to slide along the crossbeam 160. The two first guide rods 180 fixed by the two slides 170 will carry the two first clamps 1801 to extend outward. The gap between the two first clamps 1801 can facilitate the calibration of the assembly of the main pipe section inside the clamping mechanism 100. The horizontally placed smoke pipe 130 and the two guide hoods 1302 can enhance the load-bearing capacity of the main pipe section. This process facilitates the repair and welding of partially damaged air compressor housing 200. Example 2:

[0027] Combination Figures 5 to 7 As shown, based on Embodiment 1, the housing angle adjustment mechanism 300 includes a load-bearing plate 310 installed on the first guide rod 180 segment. Two symmetrically distributed arc-shaped rails 3101 are fixedly installed at both ends of the load-bearing plate 310, and a sliding groove is opened on the inner side of the arc-shaped rails 3101. An arc-shaped slider 320 is movably installed in the sliding groove. A horizontal truss 3201 is fixedly installed on the arc-shaped slider 320. A buckle plate 3202 is installed at the outer end of two adjacent trusses 3201. A double-acting screw 330 is installed in the internal thread of the buckle plate 3202. A soft pad 3301 is inserted into the inner end of the double-acting screw 330.

[0028] Preferably, one of the caps in the calibration clamping mechanism 100 is placed in the gap between two adjacent second clamps 3401 before the bidirectional screw 330 is rotated forward. After the bidirectional screw 330 moves laterally along the screw hole in the middle of the buckle plate 3202, the short soft pad 3301 installed in the bidirectional screw 330 will be pressed on the outer surface of the cap. As the bidirectional lead screw 330 rotates forward and, in conjunction with the soft pad 3301, pressurizes the cover, the end of the cover and the main pipe section will be effectively fixed. Furthermore, by enhancing the adhesion between the cover and the main pipe section, the stability of the joint after welding the air compressor housing 200 can be effectively improved, and the cracking between the cover and the main pipe section caused by stress can be reduced. Example 3:

[0029] Combination Figures 5 to 7As shown, in the above embodiment, a slide rail is provided inside the truss 3201. A compression spring 350 is fixedly installed on the plate surface of the slide rail by inserting the buckle plate 3202. A second guide rod 340 is movably installed in the slide rail. The other end of the compression spring 350 is fixedly installed on the second guide rod 340. A second clamp 3401 is installed on the inner end of the second guide rod 340. A second bolt 3402 is installed in the second guide rod 340 and the second clamp 3401. Both the arc-shaped rail 3101 and the arc-shaped slider 320 have a semi-circular structure, and the arc-shaped slider 320 is adapted to be inserted into the interior of the arc-shaped rail 3101; Both the first clamp 1801 and the second clamp 3401 have an arc-shaped structure, and the inner walls of the first clamp 1801 and the second clamp 3401 are provided with anti-slip pads. A rectangular slider is fixedly installed on the rod segment of the second clamp 3401, and the rectangular slider is adapted to pass through the slide rail inside the truss 3201.

[0030] Preferably, the load-bearing plate 310 is fixedly installed on the rod segment of the first guide rod 180. When the first guide rod 180 carries the first clamp 1801 and extends relative to each other, the load-bearing plate 310, together with the two arc-shaped rails 3101, will drive the four arc-shaped sliders 320 and the four trusses 3201 to extend synchronously. The four second guide rods 340 and the four second clamps 3401, which are movably installed in the slides inside the four trusses 3201, will enhance the clamping force on the two caps, further enhance the firmness of the two caps after closing the two ends of the main pipe segment, ensure the accuracy of the main pipe segment and the two caps after closing, and effectively enhance the stability of the air compressor housing 200 after welding.

[0031] The working principle and usage process of this invention are as follows: When in use, the hydraulic component 150 is pre-operated until the hydraulic rod inside the hydraulic component 150 extends outward. The end plate 1501 installed at the outer end of the hydraulic rod will pull the traction frame 1502 to extend outward. The traction frame 1502 will drive the chuck 1503 to lift upward. At the same time, the two traction plates 1504 installed in the chuck 1503 will simultaneously push the two column heads 1701 and the slide block 170 to slide outward along the crossbeam 160. Finally, the two slide blocks 170 will drive the two positioning plates 1702 to extend synchronously. Furthermore, the two sets of first guide rods 180 and first clamps 1801 will expand outward to their maximum state. Then, the main tube section of the calibration clamping mechanism 100 will be placed along the gap between the two first clamps 1801. The bottom of the main tube section of the calibration clamping mechanism 100 will be pressed against the smoke pipe 130 and the two guide hoods 1302. Then, according to the welding requirements, the hydraulic component 150 will be operated until the hydraulic sub-rod in the hydraulic component 150 retracts and, together with the above-mentioned components, drives the two first clamps 1801 and the two first bolts 1802 to close quickly, and quickly clamps and fixes the main tube section in the calibration clamping mechanism 100. As the two first bolts 1802 retract and fix the main pipe section inside the calibration clamping mechanism 100, one of the caps inside the calibration clamping mechanism 100 is placed inside the two second clamps 3401. Meanwhile, the two load-bearing plates 310 mounted on the two first guide rods 180, along with the arc-shaped rails 3101, close and retract the main pipe section inside the calibration clamping mechanism 100. Correspondingly, the two second clamps 3401, which retract synchronously with the two first bolts 1802, will... The cap to be welded is clamped and fixed in the calibration clamping mechanism 100 until the main pipe section and the cap section in the calibration clamping mechanism 100 can be aligned in the horizontal direction. Then, the double-acting screw 330 is rotated forward until the soft pad 3301 approaches the plate surface of the cap in the calibration clamping mechanism 100. Finally, the soft pad 3301 will press the cap tightly on the port of the main pipe section, and the joint of the main pipe section and the cap in the calibration clamping mechanism 100 is located at the center of the groove of the guide shroud 1302. Next, the user uses a welding torch to perform welding along the joint of the main pipe section and the cap inside the calibration clamping mechanism 100. At the same time, the external pipe is connected to the exhaust pipe 140, and air is discharged to the outside through the exhaust pipe 140. The smoke generated by the welding of the main pipe section and the cap will be transferred to the smoke exhaust chamber 1301 through the gap inside the two guide hoods 1302. Finally, the smoke will be released to the outside from the exhaust pipe 140, ensuring the cleanliness of the welding environment around the calibration clamping mechanism 100 and avoiding the pollution of the environment around the calibration clamping mechanism 100 by smoke, which could cause problems such as obstruction.
