Technical Field

[0001] This utility model belongs to the field of welding tooling technology, specifically relating to welding tooling for elevator traction machine bases. Background Technology

[0002] An elevator traction machine base welding fixture is a type of clamp used to fix, position, and support the various components of the elevator traction machine base during the welding process, ensuring welding accuracy and structural stability. It typically uses locating pins, clamping devices, or a hydraulic system to precisely fix the various parts of the base in predetermined positions, ensuring that the parts do not shift during welding. Using this elevator traction machine base welding fixture not only improves welding accuracy and ensures the relative positional accuracy of the base components, reducing welding errors, but also increases production efficiency, reduces manual adjustment time, and improves welding overall efficiency.

[0003] Chinese Patent Publication No. CN216421496U discloses a large machine base welding fixture, characterized by comprising a working platform, end plate positioning seats, side plate positioning seats, and clamping seats. Two end plate positioning seats are symmetrically and detachably fixedly connected to the left and right sides of the working platform's horizontal plane, respectively, for positioning and clamping the front and rear plates of the workpiece. The side plate positioning seats are detachably and fixedly connected to the front side of the working platform's horizontal plane, for positioning the front side plate of the workpiece. Two clamping seats are arranged side-by-side and detachably fixedly connected to the left and right ends of the workpiece's rear side on the working platform, for clamping the workpiece in the width direction. This utility model has a simple structure, accurate positioning, and convenient clamping. It can be used for welding machine bases of various sizes and specifications, improving work efficiency and welding quality. Only one operator is needed to complete the welding operation, saving significant labor costs and the cost of multiple welding fixtures.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1:

[0029] Please see Figure 1-5 This utility model provides a welding fixture for an elevator traction machine base, comprising:

[0030] Welding fixture 1 and machine base body 2;

[0031] The mounting frame 3 is set inside the welding fixture 1. The machine base body 2 is set on both sides of the upper end of the welding fixture 1. The mounting frame 3 has mounting shafts 4 at both ends, and the two mounting shafts 4 are rotatably connected to the two sides of the inner wall of the welding fixture 1.

[0032] Multiple mounting plates 5 are all set inside the mounting frame 3. The mounting plates 5 are provided with mounting grooves, and multiple matching fixing blocks 6 are provided in the mounting grooves. The multiple fixing blocks 6 are provided with fixing holes.

[0033] Multiple limiting plates 7 are respectively set at both ends of multiple mounting plates 5. The inner walls of the mounting frame 3 are provided with limiting grooves that are adapted to the limiting plates 7. The multiple limiting plates 7 are respectively located in two limiting grooves and are slidably connected to the side walls of the limiting grooves.

[0034] Specifically, such as Figure 1 and Figure 2 As shown, a drive motor 8 is provided on one side of the welding fixture 1. The drive motor 8 is existing technology and will not be described in detail here. The output end of the drive motor 8 passes through one side of the welding fixture 1 and is provided with a drive wheel 9. An installation wheel 10 adapted to the drive wheel 9 is provided on the outer side of the installation shaft 4 on one side. The installation wheel 10 is meshed with the drive wheel 9. When the drive motor 8 starts, its output end will drive the drive wheel 9 to rotate, which will drive the installation wheel 10 and the installation shaft 4 on one side to rotate. When the installation shaft 4 rotates, it will drive the installation frame 3 to rotate, which can conveniently adjust the angle of the elevator traction machine base and facilitate welding processing at different positions.

[0035] Specifically, such as Figure 3 and Figure 4 As shown, positioning grooves are provided on both sides of the mounting groove, and positioning plates 11 that are adapted to the positioning grooves are provided on both sides of the multiple fixing blocks 6. The multiple positioning plates 11 are located in the positioning grooves on both sides and are slidably connected to the side wall of the positioning groove.

[0036] Through its design, by using the positioning slots on both sides of the mounting slot, and in conjunction with the positioning plates 11 on both sides of the multiple fixing blocks 6, the position of the fixing blocks 6 can be conveniently adjusted while limiting their position, so that they can be adapted to elevator traction machine bases of different sizes and specifications.

[0037] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, each of the two positioning slots is provided with a clamping plate 12 on one side. The two clamping plates 12 abut against one side of the multiple positioning plates 11 respectively. Each of the two clamping plates 12 is rotatably connected to a threaded rod 13. Each of the two positioning slots is provided with a threaded hole that matches the threaded rod 13. The two threaded rods 13 pass through the two threaded holes respectively and are threadedly connected to the side wall of the threaded holes. By rotating the threaded rod 13, the clamping plate 12 can be moved so that the clamping plate 12 abuts against one side of the multiple positioning plates 11 in the positioning slot. This can limit their position and prevent them from shifting during the welding of the elevator traction machine base, thereby ensuring the stability of the elevator traction machine base installation.

[0038] Specifically, such as Figure 2 and Figure 3 As shown, a plurality of guide rods 14 are provided on one side of the clamping plate 12. One end of each guide rod 14 passes through the positioning groove and extends to the outside. The multiple guide rods 14 can limit the movement of the clamping plate 12 and prevent its position from shifting, thereby ensuring the accuracy of its fixation of the fixing block 6.

[0039] Specifically, such as Figure 2 and Figure 4 As shown, each of the multiple limiting plates 7 is provided with a fixing bolt 15 at its upper end. The upper ends of the multiple fixing bolts 15 pass through the upper ends of the two limiting grooves and extend to the outside. Each of the multiple fixing bolts 15 is fitted with a fixing nut 16 on its outer side. The bottom ends of the multiple fixing nuts 16 abut against the upper end of the mounting frame 3. By rotating the multiple fixing bolts 15, the multiple fixing nuts 16 abut against the upper end of the mounting frame 3, which can stably limit the position of the multiple limiting plates 7, thereby limiting the position of the multiple mounting plates 5 and ensuring the stability of the welding fixture in fixing the elevator traction machine base.

[0040] Example 2:

[0041] Please see Figure 1-5 This utility model provides a welding fixture for an elevator traction machine base, comprising:

[0042] Welding fixture 1 and machine base body 2;

[0043] The mounting frame 3 is set inside the welding fixture 1. The machine base body 2 is set on both sides of the upper end of the welding fixture 1. The mounting frame 3 has mounting shafts 4 at both ends, and the two mounting shafts 4 are rotatably connected to the two sides of the inner wall of the welding fixture 1.

[0044] Multiple mounting plates 5 are all set inside the mounting frame 3. The mounting plates 5 are provided with mounting grooves, and multiple matching fixing blocks 6 are provided in the mounting grooves. The multiple fixing blocks 6 are provided with fixing holes.

[0045] Multiple limiting plates 7 are respectively set at both ends of multiple mounting plates 5. The inner walls of the mounting frame 3 are provided with limiting grooves that are adapted to the limiting plates 7. The multiple limiting plates 7 are respectively located in two limiting grooves and are slidably connected to the side walls of the limiting grooves.

[0046] Specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, a rectangular groove is provided in the mounting frame 3, and multiple dust suction holes 17 are provided through both sides of the rectangular groove. The mounting shaft 4 located on one side is provided with a snap-fit ​​groove that connects to the rectangular groove. A blower 18 is provided on one side of the welding fixture 1. The blower 18 is existing technology and will not be described in detail here. A filter box 19 is provided at the air inlet end of the blower 18. A dust suction pipe 20 that is adapted to the snap-fit ​​groove is provided at the upper end of the filter box 19. The other end of the dust suction pipe 20 is located in the snap-fit ​​groove and is rotatably connected to the inner wall of the snap-fit ​​groove.

[0047] By starting the exhaust fan 18, the air in the rectangular slot can be drawn through the dust extraction pipe 20 to create a negative pressure state. This allows the smoke and dust generated from welding the elevator traction machine base to be absorbed through multiple dust extraction holes 17. The smoke and dust are then drawn into the filter box 19 to filter out particulate matter or impurities in the smoke and dust, effectively ensuring the cleanliness of the working environment and the health and safety of the operators.

[0048] Specifically, such as Figure 3 and Figure 5 As shown, a filter plate 21 is provided inside the filter box 19. One end of the filter plate 21 passes through one side of the filter box 19 and extends to the outside. By disassembling the filter plate 21, the filtered particles or impurities can be easily cleaned, thereby ensuring the effect of smoke and dust absorption.

[0049] See Figure 1-5When using welding fixtures to install and fix the elevator traction machine base, firstly, the positions of multiple mounting plates 5 need to be adjusted according to the size of the elevator traction machine base, and the positions of multiple mounting plates 5 are fixed by multiple fixing bolts 15 and multiple fixing nuts 16. Next, the positions of multiple fixing blocks 6 are adjusted, and then multiple threaded rods 13 are rotated. The multiple threaded rods 13 will drive multiple clamping plates 12 to move, so that the multiple clamping plates 12 abut against one side of the multiple fixing blocks 6, thereby fixing the positions of the multiple fixing blocks 6. By adjusting the positions of multiple mounting plates 5 and multiple fixing blocks 6, the welding fixture can be adapted to elevator traction machine bases of different sizes and specifications. During the welding process of the elevator traction machine base, a large amount of smoke and dust will be generated. When dealing with the smoke and dust, the exhaust fan 18 needs to be turned on. The exhaust fan 18 will absorb the smoke and dust through the rectangular groove and multiple dust suction holes 17, and filter it through the filter plate 21 in the filter box 19, thereby effectively preventing the smoke and dust from affecting the operators or the working environment.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
