Abstract
Description
Technical Field
[0001] This utility model belongs to the field of clamping technology, specifically relating to a conveniently adjustable welding clamp for the longitudinal beam of a mining truck. Background Technology
[0002] In the welding operation of longitudinal beams of mining trucks, the clamping and fixing function of the fixture is crucial. It can firmly lock the longitudinal beam in the preset welding position through precise force constraint, effectively avoiding uneven stress caused by factors such as arc impact and thermal expansion and contraction of metal during the welding process, fundamentally eliminating the phenomenon of longitudinal beam shaking, and ensuring stability during welding.
[0003] However, in the current widely used welding fixtures, operators need to repeatedly adjust multiple positioning bolts and clamping mechanisms to fix the longitudinal beam. This purely manual adjustment method not only consumes a lot of physical strength but also suffers from low adjustment efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a conveniently adjustable welding fixture for the longitudinal beams of mining trucks. This addresses the problem of currently widely used welding fixtures where operators need to repeatedly adjust multiple positioning bolts and clamping mechanisms to secure the longitudinal beams. This purely manual adjustment method is not only physically demanding but also inefficient.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a conveniently adjustable longitudinal beam welding fixture for mining trucks, comprising a work frame, a fixing plate welded to the outer wall of one end of the work frame, and a first mounting plate welded to the outer wall of one side of the fixing plate;
[0006] Two slide rails are symmetrically installed on the surface of the work frame away from the fixed plate. A movable plate is movably installed on the two slide rails. A second mounting plate is welded to the outer wall of the movable plate facing the fixed plate. The other outer wall of the movable plate is detachably and fixedly connected to the telescopic end of the electric telescopic rod. The bottom of the electric telescopic rod is mounted on the surface of the work frame.
[0007] In order to enable the two supports to support the bottom of the second platform after one end of the longitudinal beam of the mining truck is placed on the second platform, thereby improving the strength of the second platform, as a conveniently adjustable welding fixture for the longitudinal beam of the mining truck of this utility model, preferably, two supports are symmetrically welded to the bottom of the second platform, and the bottom of each support is movably abutting against the surface of the work frame.
[0008] Two guide grooves are symmetrically formed on the surface of one end of the work frame, and the bracket is set between the two guide grooves.
[0009] In order to reduce the friction between the bottom of the movable plate and the surface of the work frame when the movable plate moves, as a conveniently adjustable welding fixture for the longitudinal beam of a mining truck, preferably, a sliding groove is opened at the bottom of the movable plate near both ends to slide and engage with the slide rail, and a protrusion is installed on the bottom of the movable plate between the two sliding grooves.
[0010] The protrusion has a semi-circular structure, and the bottom of the protrusion is in contact with the inner wall of the guide groove.
[0011] In order to ensure that the longitudinal beam of the mining truck is clamped between the fixed plate and the movable plate, the suspended end of the longitudinal beam can be supported by three sets of threaded telescopic rods. As a conveniently adjustable welding fixture for the longitudinal beam of the mining truck according to this utility model, preferably, three rotating seats are installed on the working frame surface between the fixed plate and the movable plate, and the rotating end of each rotating seat is respectively sleeved on the bottom of a threaded telescopic rod.
[0012] In order to limit the maximum travel of the movable plate, as a conveniently adjustable welding fixture for the longitudinal beam of a mining truck according to this utility model, preferably, one end of the slide rail is connected to one end of the stop block, and the bottom of the stop block is welded to the surface of the work frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In operation, both ends of the longitudinal beam of the mining truck to be welded are placed on the first and second mounting plates, respectively. Then, the electric telescopic rod is activated to push the movable plate towards the side of the fixed plate. As the movable plate moves, it travels along the track of the slide rail and guide groove via the bottom groove and protrusion. This causes the movable plate to move the second mounting plate at the bottom of the longitudinal beam to be welded. This reduces the distance between the movable and fixed plates, ultimately clamping both ends of the longitudinal beam. Welding can then be performed on the clamped and fixed longitudinal beam. This method requires no excessive manual intervention during clamping and adjustment, making the overall adjustment operation very simple. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 The present invention provides the following technical solution: a conveniently adjustable longitudinal beam welding fixture for mining trucks, including a work frame 1, a fixing plate 2 welded to the outer wall of one end of the work frame 1, and a first lap plate 3 welded to the outer wall of one side of the fixing plate 2.
[0023] During operation, the longitudinal beam of the mining truck to be welded is transported to the first platform 3 and the second platform 6 of the work frame 1 using a hoisting device. Then, the position of the movable plate 5 is adjusted so that the longitudinal beam of the mining truck to be welded is clamped between the fixed plate 2 and the movable plate 5. In this way, the longitudinal beam of the mining truck is fixedly suspended in the air during the welding process, which facilitates subsequent welding operations.
[0024] Two slide rails 4 are symmetrically installed on the surface of the work frame 1 away from the fixed plate 2. A movable plate 5 is movably installed on the two slide rails 4. A second mounting plate 6 is welded to the outer wall of the movable plate 5 facing the fixed plate 2. The other outer wall of the movable plate 5 is detachably and fixedly connected to the telescopic end of the electric telescopic rod 8. The bottom of the electric telescopic rod 8 is installed on the surface of the work frame 1.
[0025] Preferably, two supports 7 are symmetrically welded to the bottom of the second mounting plate 6, and the bottom of each support 7 is movably abutting against the surface of the work frame 1.
[0026] Two guide grooves 13 are symmetrically opened on the surface of one end of the work frame 1, and the bracket 7 is set between the two guide grooves 13.
[0027] In practical use, when the second access plate 6 is subjected to downward pressure from one end of the longitudinal beam of the mining truck, the second access plate 6 will transmit the pressure to the two supports 7. The supports 7 then transmit the pressure to the surface of the work frame 1, thereby enhancing the load-bearing strength of the second access plate 6;
[0028] The bottom of the support 7 has a semi-circular structure, which can improve the smoothness of movement on the surface of the support 7 work frame 1 and reduce friction when the support 7 moves.
[0029] Preferably, a groove 51 is provided at the bottom of the movable plate 5 near both ends, which is slidably connected to the slide rail 4, and a protrusion 52 is installed at the bottom of the movable plate 5 between the two grooves 51.
[0030] The protrusion 52 has a semi-circular structure, and the bottom of the protrusion 52 is in contact with the inner wall of the guide groove 13.
[0031] In actual use, when the electric telescopic rod 8 is working, it will push the movable plate 5 to move. When the movable plate 5 moves, it will slide on the outer wall of the slide rail 4 through the slide groove 51, so that the movable plate 5 can move along a fixed track.
[0032] When the movable plate 5 moves, its bottom suspended end will contact the guide groove 13 through the protrusion 52, so that the movable plate 5 can also improve the stability of the bottom through the protrusion 52.
[0033] Preferably, three rotating seats 11 are installed on the surface of the work frame 1 between the fixed plate 2 and the movable plate 5, and the rotating end of each rotating seat 11 is respectively sleeved on the bottom of a threaded telescopic rod 12.
[0034] In practical use, after the longitudinal beam of the mining truck is clamped and fixed by the movable plate 5 to the fixed plate 2, the threaded telescopic rod 12 is then rotated to a vertical state via the rotating seat 11. Next, the movable end of the threaded telescopic rod 12 is adjusted upward so that it supports the suspended end of the longitudinal beam of the mining truck. This supports the suspended end of the longitudinal beam of the mining truck to prevent deformation of the suspended end.
[0035] Preferably, one end of the slide rail 4 is connected to one end of the stop block 41 on its outer wall, and the bottom of the stop block 41 is welded to the surface of the work frame 1.
[0036] Working principle: During use, place both ends of the longitudinal beam of the mining truck to be welded on the first mounting plate 3 and the second mounting plate 6 respectively. Then, activate the electric telescopic rod 8 to push the movable plate 5 to one side of the fixed plate 2. When the movable plate 5 moves, it will move along the track of the slide rail 4 and the guide groove 13 through the bottom slide groove 51 and the protrusion 52. In this way, the movable plate 5 will drive the second mounting plate 6 to move at the bottom of the longitudinal beam of the mining truck to be welded.
[0037] This reduces the distance between the movable plate 5 and the fixed plate 2, ultimately clamping both ends of the longitudinal beam of the mining truck. The clamped and fixed longitudinal beam can then be welded. This method eliminates the need for excessive manual intervention during clamping and adjustment, making the overall adjustment operation very simple.
[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
