Technical Field

[0001] This utility model relates to a hydraulic oil pipe spot welding fixture. Background Technology

[0002] Hydraulic hoses are mainly used to transmit hydraulic oil to ensure the normal operation of machinery. Their main structure consists of pipe fittings welded to pipes of various shapes. However, during the welding process, problems such as misalignment and large weld points often occur, affecting the quality of the weld. This places extremely high demands on the skill level of the operators. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a hydraulic oil pipe spot welding fixture with simple structure and reliable operation.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is: a hydraulic oil pipe spot welding fixture, including a base, two pressure plates are symmetrically arranged on both sides of the base, the bottom ends of the pressure plates are installed on the base, a V-shaped block is arranged directly below each pressure plate, the V-shaped block is detachably installed on the base, and a bolt is provided on the pressure plate at the position directly above the V-shaped block.

[0005] The aforementioned hydraulic pipe spot welding fixture has four mounting seats protruding from the four corners of the upper surface of the base. The two ends of the base of each pressure plate are respectively mounted on the two mounting seats on the corresponding side by fixing pins and nuts.

[0006] In the aforementioned hydraulic oil pipe spot welding fixture, one end of the V-block is fixed to the base by an internal hexagon screw, and the other end of the V-block is fixed to the base by a fixing pin.

[0007] The aforementioned hydraulic pipe spot welding fixture has a slot in the middle of the upper surface of the V-shaped block for placing the hydraulic pipe.

[0008] The aforementioned hydraulic pipe spot welding fixture is suitable for welding hydraulic pipes of various structures by replacing the V-blocks of various specifications.

[0009] The aforementioned hydraulic oil pipe spot welding fixture has a pressure plate that can be opened and closed when one side of the fixing pin is removed.

[0010] The beneficial effects of this utility model are as follows: This utility model has two V-shaped blocks on the base for placing hydraulic oil pipes. Each V-shaped block has a pressure plate with a clamping nut on it. By tightening the clamping nut, the hydraulic oil pipe can be locked, thereby preventing misalignment of the pipe fittings during spot welding and improving the welding quality of the pipe fittings.

[0013] Figure 3 This is a cross-sectional view of the V-shaped block. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 , Figure 2 As shown, a hydraulic oil pipe spot welding fixture includes a base 2. Two pressure plates 1 are symmetrically arranged on both sides of the base 2. The bottom ends of the pressure plates 1 are installed on the base 2. A V-shaped block 3 is provided directly below each pressure plate 1. The V-shaped block 3 is detachably installed on the base 2. A bolt 5 is provided on the pressure plate 1 at the position directly above the V-shaped block 3.

[0016] The base 2 has four mounting seats protruding from its four corners on its upper surface. Each pressure plate 1 has its base 2 ends mounted on two mounting seats on the corresponding side by fixing pins 6 and nuts 7. The pressure plate 1 can be opened and closed when one fixing pin 6 is removed.

[0017] One end of the V-block 3 is fixed to the base 2 by an internal hex screw 4, and the other end of the V-block 3 is fixed to the base 2 by a fixing pin 8.

[0018] The upper surface of the V-block 3 has a groove 9 in the middle for placing hydraulic oil pipes. The hydraulic oil pipes are placed in the groove 9 and then tightened by the clamping nut 7 for greater stability.

[0019] Since the V-block 3 can be detachably mounted on the base 2, it can be used for welding hydraulic oil pipes of various structures by replacing the V-block 3 with various specifications.

[0020] The working process of this utility model is as follows:

[0021] 1) Connect and fix the two V-blocks 3 to the base 2 using hex socket screws 4 and fixing pins 8;

[0022] 2) Fix the two end pressure plates 1 with fixing pins 8, nails 6 and nuts 7, and screw bolts 5 into the pressure plates 1;

[0023] 3) First, place the first hydraulic oil pipe into the slot 9 of the V-block 3 on the right end, adjust it to a suitable position, and fix the hydraulic oil pipe with the adjusting bolt 5; then first, place the second hydraulic oil pipe into the slot 9 of the V-block 3 on the left end, adjust it to contact the first hydraulic oil pipe, and then fix the second hydraulic oil pipe with the adjusting bolt 5.

[0024] 4) Operators use welding torches to spot weld the contact points of the two hydraulic oil pipes, which can prevent misalignment during spot welding and improve the welding quality of the pipe fittings.

[0025] 5) Remove the fixing pin 8 or nail 6 from one side of the pressure plate 1 at both ends, or loosen the bolt 5, open the pressure plate 1, and take out the spot-welded hydraulic oil pipe.
