Description

Technical Field

[0001] This utility model relates to the field of workpiece welding technology, specifically a large-scale rail welding fixture. Background Technology

[0002] Chinese patent CN218193407U discloses a welding track positioning fixture, including a track body, a movable seat, a clamping plate, and a movable base. Two movable seats are provided, both slidably mounted on the inner wall of the track body. When the workpiece is long, the track body with an internal connecting rod is installed in the connecting cavity, allowing the connecting rod inside one track body to slide into the connecting cavity inside the other movable seat. A clamping rod is then inserted into the connecting rod, assembling the two movable seats. The inner clamping plates are then removed, and the outer clamping plates of the two movable seats cooperate to clamp the workpiece. This allows the device to be adjusted according to welding requirements without requiring the worker to disassemble the entire track body, resulting in a simple structure that saves time and effort. The patent describes sliding the movable seat along the track body. However, to ensure smooth sliding of the movable seat along the track, the track needs to be horizontally positioned. Existing track configurations have significant limitations and are not conducive to the design of welding fixtures.

[0003] Based on this, a large-scale rail welding fixture was designed to solve the problem. Utility Model Content

[0004] The purpose of this utility model is to provide a large-scale rail welding fixture to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the utility model provides the following technical solution: a large track welding fixture, comprising multiple sets of movable tracks and multiple sets of movable seats, wherein the multiple sets of movable tracks are arranged parallel to each other, the multiple sets of movable seats are arranged parallel to each other along the movable tracks, the multiple sets of movable seats and the multiple sets of movable tracks are slidably connected to each other, multiple sets of fixing components are provided on the side of the movable track away from the movable seats, the multiple sets of fixing components are equidistant from each other along the movable track, each fixing component includes a first fixing rod, a support plate is slidably sleeved on the first fixing rod, the support plate is groove-shaped, the movable track matches the groove surface of the support plate, multiple sets of support rods are provided between the movable track and the support plate, one end of the support rod is threadedly connected to the movable track, the side of the support rod away from the movable track abuts against the support plate, and the multiple sets of support rods are symmetrically arranged about the axis of the movable track. By sliding the support plate on the first fixed rod, the support plate comes into contact with the fixed surface, which helps to increase the contact area. The support plate and the first fixed rod are slidably arranged to make contact with the fixed surface when the height of the fixed surface is uneven. The support rod and the moving track are threaded together. By rotating the support rod, it is easy to control the length of the support rod extending out of the moving track, so that the support rod and the support plate abut against each other to support the moving track.

[0006] Preferably, the moving track is provided with multiple sets of second grooves, which are symmetrically arranged about the axis of the moving track, and the multiple sets of support rods are respectively matched with the multiple sets of second grooves.

[0007] By adopting the above technical solution, the support rod is embedded in the second groove opened on the moving track, which avoids the support rod protruding from the top of the moving track and hindering the moving seat from moving laterally along the moving track when it is not rotated and extends downward out of the moving track.

[0008] Preferably, the first fixing rod is made of an expansion bolt, and the end of the first fixing rod away from the fixing surface abuts against the upper side of the moving track, and the end of the first fixing rod away from the moving track is engaged with the fixing surface.

[0009] By adopting the above technical solution, the expansion bolt is a part used for fastening and installation operations. It is convenient to fix the moving track on different fixed surfaces, which is beneficial for setting up the moving track. In addition, the expansion bolt can also be a pull-out type expansion screw, which avoids a long screw head being exposed after installation, so that the screw head extends out of the moving track and hinders the moving seat from moving laterally along the moving track.

[0010] Preferably, the moving track is provided with multiple sets of first grooves, and the multiple sets of first grooves are respectively matched with multiple sets of first fixing rods, with the first fixing rods embedded in the first grooves.

[0011] By adopting the above technical solution, the first fixing rod is embedded in the first groove, which helps to prevent the first fixing rod from protruding from the upper side of the moving track and hindering the moving seat from moving laterally along the moving track.

[0012] Preferably, multiple sets of horizontal plates are provided between the multiple sets of moving tracks. The horizontal plates abut against and match the lower sidewalls of the multiple sets of moving tracks. The axis of the horizontal plate is perpendicular to the axis of the moving track. Multiple sets of second fixing rods are provided at equal intervals on the horizontal plate. One end of the second fixing rod abuts against and matches the upper side of the horizontal plate, and the end of the second fixing rod away from the horizontal plate is engaged with the fixing surface.

[0013] By adopting the above technical solution and setting a crossbar between adjacent sets of moving tracks, it is beneficial to calibrate the height of multiple sets of moving tracks uniformly, avoiding differences in the height of multiple sets of moving tracks that would hinder the lateral movement of the moving seat along the moving tracks. Furthermore, the second fixing rod and the first fixing rod are made of the same expansion bolts.

[0014] Preferably, the horizontal plate is provided with multiple sets of side plates, the number of side plates is even, and two sets of side plates are respectively provided on opposite sides of the moving track, and the two sets of side plates are symmetrical about the axis of the moving track.

[0015] By adopting the above technical solution, and by setting side plates on the horizontal plate, so that the two sets of side plates are located on opposite sides of the moving track, the moving track is restricted by the symmetrically set side plates on both sides, which helps to keep the spacing between different positions of multiple sets of moving tracks consistent.

[0016] Preferably, the movable base includes a welding table and a support base. The support base is disposed on the side of the welding table near the movable track. The support base and the movable track slide against each other. The side of the support base near the movable track is provided with a pin hole. A locking pin is slidably disposed in the pin hole. The movable track is provided with multiple sets of fixing holes. The locking pin is engaged with each of the multiple sets of fixing holes. The multiple sets of fixing holes are equidistant from each other along the fixed track.

[0017] By adopting the above technical solution, the locking pin on the movable seat and the fixing hole on the movable track are matched and engaged with each other. After the position of the movable seat is adjusted, the movable seat is fixed on the movable track. The fixing hole and the first groove are on the same plane, which helps to reduce the influence of the first groove on the sliding of the movable seat along the movable track.

[0018] Compared with the prior art, the advantages of this utility model are as follows: This utility model slides a support plate on the first fixed rod so that the support plate contacts the fixed surface, which helps to increase the contact area. The support plate and the first fixed rod slide against each other, which makes it easy to contact the fixed surface when the height of the fixed surface is uneven. The support rod and the moving track are threaded together. By rotating the support rod, it is easy to control the length of the support rod extending out of the moving track, so that the support rod and the support plate abut against each other to support the moving track.

[0026] Combination Figure 1-3 :

[0027] Reference Figure 1 , 2As shown in Figures 1 and 3, a large track welding fixture includes multiple sets of movable tracks 1 and multiple sets of movable seats 2. The multiple sets of movable tracks 1 are arranged parallel to each other, and the multiple sets of movable seats 2 are arranged parallel to each other along the movable tracks 1. The multiple sets of movable seats 2 and the multiple sets of movable tracks 1 are slidably connected to each other. Multiple sets of fixing components 3 are provided on the side of the movable track 1 away from the movable seats 2. The multiple sets of fixing components 3 are equidistant from each other along the movable track 1. The fixing components 3 include a first fixing rod 31, and a support plate 32 is slidably sleeved on the first fixing rod 31. The support plate 32 is arranged in a groove shape. The movable track 1 and the support plate 32 are connected in a groove shape. The grooved surfaces of the support plates 32 are matched with each other. Multiple sets of support rods 33 are provided between the moving track 1 and the support plate 32. One end of each support rod 33 is threadedly connected to the moving track 1. The side of the support rod 33 away from the moving track 1 abuts against the support plate 32. The multiple sets of support rods 33 are symmetrically arranged about the axis of the moving track 1. By rotating the support rods 33, they extend out of the moving track 1, causing the support plate 32 to move downwards along the first fixed rod 31, allowing the support plate 32 to abut against different positions on the fixed surface, thus supporting the moving track 1. Multiple sets of second grooves 34 are provided on the moving track 1, symmetrically arranged about the axis of the moving track 1. The multiple sets of support rods 33 are matched with the multiple sets of second grooves 34 respectively. By sliding the support plate 32 on the first fixed rod 31, the support plate 32 comes into contact with the fixed surface, which helps to increase the contact area. The sliding arrangement of the support plate 32 and the first fixed rod 31 facilitates contact with the fixed surface even when the surface is uneven. The support rod 33 is threadedly connected to the moving track 1. Rotating the support rod 33 allows control over its extension length from the moving track 1, ensuring that the support rod 33 abuts against the support plate 32 to support the moving track 1. The support rod 33 is embedded within the second groove 34 on the moving track 1 to prevent it from protruding from the top of the moving track 1 and obstructing the lateral movement of the moving seat 2 along the moving track 1 when it is not rotated downwards and extending downwards.

[0028] Reference Figure 1 , 2As shown in Figure 3, the first fixing rod 31 is made of an expansion bolt. The end of the first fixing rod 31 away from the fixing surface abuts against the upper side of the moving track 1, while the other end of the first fixing rod 31 away from the moving track 1 engages with the fixing surface. The moving track 1 has multiple sets of first grooves 35, each set matching one of the first fixing rods 31. The first fixing rod 31 is embedded within the first groove 35. An expansion bolt is a component used for fastening installation, facilitating the fixing of the moving track 1 to different fixing surfaces. This is beneficial for setting up the moving track 1. Furthermore, the expansion bolt can be a pull-out type, preventing a long screw head from protruding from the moving track 1 after installation, thus avoiding obstruction of the moving seat 2's lateral movement along the moving track 1. The first fixing rod 31 being embedded within the first groove 35 helps prevent it from protruding from the upper side of the moving track 1, thus preventing obstruction of the moving seat 2's lateral movement along the moving track 1.

[0029] Reference Figure 1 , 2 As shown in Figure 3, multiple sets of horizontal plates 4 are provided between multiple sets of moving tracks 1. The horizontal plates 4 abut against the lower sidewalls of the multiple sets of moving tracks 1. The axis of the horizontal plate 4 is perpendicular to the axis of the moving track 1. Multiple sets of second fixing rods 41 are provided at equal intervals on the horizontal plate 4. One end of the second fixing rod 41 abuts against the upper side of the horizontal plate 4, and the end of the second fixing rod 41 away from the horizontal plate 4 is engaged with the fixing surface. Multiple sets of side plates 42 are provided on the horizontal plate 4. The number of side plates 42 is even. Two sets of side plates 42 are respectively provided on opposite sides of the moving track 1, and the two sets of side plates 42 are symmetrical about the axis of the moving track 1. By setting horizontal plates 4 between adjacent sets of moving tracks 1, it is beneficial to calibrate the setting height of multiple sets of moving tracks 1 at the same time, avoiding different setting heights of multiple sets of moving tracks 1, which would hinder the lateral movement of the moving seat 2 along the moving track 1. Moreover, the second fixing rods 41 and the first fixing rods 31 are made of the same expansion bolts. By setting side plates 42 on the horizontal plate 4, the two sets of side plates 42 are located on opposite sides of the moving track 1. The side plates 42 set symmetrically on both sides restrict the moving track 1, which helps to keep the spacing between different positions of multiple sets of moving tracks 1 consistent.

[0030] Reference Figure 1 , 3As shown, the movable base 2 includes a welding table 21 and a support base 22. The support base 22 is located on the side of the welding table 21 near the movable track 1, and the support base 22 and the movable track 1 slide against each other. The support base 22 near the movable track 1 has a pin hole 23, and a locking pin 24 is slidably installed in the pin hole 23. The movable track 1 has multiple sets of fixing holes 25, and the locking pin 24 engages with each of the multiple sets of fixing holes 25. The multiple sets of fixing holes 25 are equidistant from each other along the fixed track 1. By engaging the locking pin 24 on the movable base 2 with the fixing holes 25 on the movable track 1, after the position of the movable base 2 is adjusted, the movable base 2 is fixed on the movable track 1. The fixing holes 25 and the first groove 35 are located on the same plane, which helps to reduce the influence of the first groove 35 on the sliding of the movable base 2 along the movable track 1.

[0031] Specific application examples of this utility model:

[0032] By sliding the support plate 32 on the first fixed rod 31, the support plate 32 comes into contact with the fixed surface, which helps to increase the contact area. The support plate 32 and the first fixed rod 31 are slidably arranged to make contact with the fixed surface when the height of the fixed surface is uneven. The support rod 33 is threadedly connected to the moving track 1. By rotating the support rod 33, it is easy to control the length of the support rod 33 extending out of the moving track 1, so that the support rod 33 and the support plate 32 abut against each other to support the moving track 1.

[0033] The support rod 33 is embedded in the second groove 34 opened on the moving track 1 to prevent the support rod 33 from protruding from the upper side of the moving track 1 and hindering the moving seat 2 from moving laterally along the moving track 1 when the support rod 33 is not rotated and extends downward out of the moving track 1.

[0034] Expansion bolts are parts used for fastening installation operations. They facilitate fixing the moving track 1 to different fixed surfaces, which is beneficial for setting up the moving track 1. Furthermore, expansion bolts can also be pull-out type expansion screws to prevent a long screw head from protruding after installation, which would extend out of the moving track 1 and hinder the lateral movement of the moving seat 2 along the moving track 1.

[0035] The first fixing rod 31 is embedded in the first groove 35, which helps to prevent the first fixing rod 31 from protruding from the upper side of the moving track 1 and hindering the moving seat 2 from moving laterally along the moving track 1.

[0036] By setting a horizontal plate 4 between multiple adjacent sets of moving tracks 1, it is beneficial to calibrate the height of multiple sets of moving tracks 1 at the same level, avoiding the problem of different heights of multiple sets of moving tracks 1 hindering the lateral movement of the moving seat 2 along the moving track 1. Furthermore, the second fixing rod 41 and the first fixing rod 31 are made of the same expansion bolts.

[0037] By setting side plates 42 on the horizontal plate 4, the two sets of side plates 42 are located on opposite sides of the moving track 1. The side plates 42 set symmetrically on both sides restrict the moving track 1, which helps to keep the spacing between different positions of multiple sets of moving tracks 1 consistent.

[0038] The locking pin 24 on the movable seat 2 is engaged with the fixing hole 25 on the movable track 1. After the position of the movable seat 2 is adjusted, the movable seat 2 is fixed on the movable track 1. The fixing hole 25 and the first groove 35 are on the same plane, which helps to reduce the influence of the first groove 35 on the sliding of the movable seat 2 along the movable track 1.
