Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, specifically to a welding tooling for a machine base flange. Background Technology

[0002] Welding the motor base flange is a crucial step in motor manufacturing, directly affecting key indicators such as the coaxiality and sealing performance of the finished motor. The welding fixture for the motor base and flange is a specialized piece of equipment used to ensure precise positioning and clamping of the flange and base during the welding process, directly impacting the weld quality.

[0003] In the welding of the motor base and the base flange, the traditional welding fixture uses quick clamps to clamp the workpiece. First, the base is placed in the fixture base, and the inner hole positioning pin is inserted to ensure that the base is concentric. Then, the flange is placed so that its end face is close to the axial stop block and the bolt holes are aligned with the positioning pin. After positioning, the horizontal quick clamp handle is first moved to push the pressure block to press the outer edge of the flange, and then the vertical quick clamp is pressed down to make the bottom of the base and the fixture platform without gap. Although this can achieve the fixing effect, the operation is too cumbersome.

[0004] Based on this, this utility model designs a welding fixture for the flange of the machine base to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a welding fixture for the flange of the machine base.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A welding fixture for a motor base flange includes a base, a base fixing mechanism, and a flange fixing mechanism. Multiple flange fixing mechanisms are arranged in a circumferential array on the base. Both the base fixing mechanism and the flange fixing mechanism are connected to the base. The base fixing mechanism includes an inner support assembly and an oil nozzle positioning baffle. The inner support assembly for internally supporting and fixing the motor base is connected to the base. An oil nozzle is fixedly connected to the outer wall of the motor base. The oil nozzle positioning baffle for positioning and fixing the oil nozzle is connected to the base. The inner support assembly and the oil nozzle positioning baffle cooperate to fix the motor base.

[0008] Furthermore, the base includes a base welding plate, a welding plate support plate, and a leveling column. The upper end of the welding plate support plate is fixedly connected to the leveling column, the upper end of the leveling column is fixedly connected to the base welding plate, the flange fixing mechanism is connected to the base welding plate, the internal support assembly is connected to the upper end of the welding plate support plate, and the lower end of the oil nozzle positioning baffle is fixedly connected to the upper end of the base welding plate.

[0009] Furthermore, the internal support assembly includes a pneumatic chuck and a base internal support ring. The lower end of the pneumatic chuck's disc body is fixedly connected to the welded base plate support plate. The inner walls of multiple sets of base internal support rings are respectively fixedly connected to the jaws of the pneumatic chuck. The multiple sets of base internal support rings are distributed in a circumferential array about the pneumatic chuck. The lower end of the base internal support ring slides against the upper end of the welded base plate of the base.

[0010] Furthermore, the flange fixing mechanism includes a positioning column and an upper clamping assembly. The lower end of the positioning column, used for positioning the machine base flange, is fixedly connected to the welded base plate of the machine base. The upper clamping assembly, used for fixing the machine base flange, is connected to the welded base plate of the machine base.

[0011] Furthermore, the upper clamping assembly includes a corner cylinder, a base flange locking block, and an anti-tilting pressure column. The outer shell of the corner cylinder is fixedly connected to the welded base plate of the base. The output end of the corner cylinder is fixedly connected to the middle of the base flange locking block. An anti-tilting pressure column is fixedly connected to the end of the base flange locking block away from the inner support ring of the base. The end of the base flange locking block near the inner support ring of the base is used to clamp the base flange.

[0012] Furthermore, the base flange locking block has a clamping groove at one end near the inner support ring of the base for fitting and clamping the base flange.

[0013] Furthermore, the flange fixing mechanism has at least four sets;

[0014] Furthermore, when the base flange locking block moves to the lowest position to press the base flange, the included angle between the oil nozzle positioning baffle and the two adjacent sets of base flange locking blocks is 45°.

[0015] Compared with the prior art, the advantages of this utility model are as follows: 1. The oil nozzle positioning baffle makes the oil nozzle of the machine base form a 45° angle with the machine base flange, and moves the inner support ring of the machine base outward until the inner support of the motor base is in place. While fixing, it can also play a concentric positioning role. The above structures work together to fix the motor base, which is simpler to operate while satisfying the fixing effect.

[0016] 2. When the clamping groove clamps the machine base flange, the lower end of the anti-tilting pressure column abuts against the welded base plate of the machine base, which plays an anti-tilting role. The four sets of machine base flange locking blocks simultaneously press down on the machine base flange, which further improves the stability of the fixed tooling and achieves reliable positioning and fixing with simple operation.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0026] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4A welding fixture for a machine base flange includes a base 3, a base fixing mechanism 1 and a flange fixing mechanism 2. Multiple flange fixing mechanisms 2 are arranged in a circumferential array on the base 3. Both the base fixing mechanism 1 and the flange fixing mechanism 2 are connected to the base 3.

[0027] The base fixing mechanism 1 includes an inner support assembly 11 and an oil nozzle positioning baffle 12. The inner support assembly 11, which is used to internally support and fix the motor base 4, is connected to the base 3. An oil nozzle 41 is fixedly connected to the outer wall of the motor base 4. The oil nozzle positioning baffle 12, which is used to position and fix the oil nozzle 41, is connected to the base 3. The inner support assembly 11 and the oil nozzle positioning baffle 12 cooperate to fix the motor base 4.

[0028] To ensure the reliability of the fixation, the flange fixing mechanism 2 should have at least four sets.

[0029] The upper end of the oil nozzle positioning baffle 12 is covered with a silicone layer, which increases friction without damaging the oil nozzle 41 of the machine base.

[0030] like Figure 2 As shown, the base 3 includes a base welding plate 31, a welding plate support plate 32, and a leveling column 33. The upper end of the welding plate support plate 32 is fixedly connected to the leveling column 33, and the upper end of the leveling column 33 is fixedly connected to the base welding plate 31. The flange fixing mechanism 2 is connected to the base welding plate 31. The inner support assembly 11 is connected to the upper end of the welding plate support plate 32. The lower end of the oil nozzle positioning baffle 12 is fixedly connected to the upper end of the base welding plate 31.

[0031] like Figure 3 and Figure 4 As shown, the inner support assembly 11 includes a pneumatic chuck 111 and a base inner support ring 112. The lower end of the pneumatic chuck 111 is fixedly connected to the welded base plate 32. The inner walls of multiple sets of base inner support rings 112 are fixedly connected to the jaws of the pneumatic chuck 111. The multiple sets of base inner support rings 112 are distributed in a circumferential array about the pneumatic chuck 111. The lower end of the base inner support ring 112 slides against the upper end of the welded base plate 31. The pneumatic chuck 111 is a mature existing technology and will not be described in detail here.

[0032] like Figure 3 and Figure 4 As shown, the flange fixing mechanism 2 includes a positioning column 21 and an upper clamping assembly 22. The lower end of the positioning column 21, which is used to position the base flange 5, is fixedly connected to the base welding plate 31. The upper clamping assembly 22, which is used to fix the base flange 5, is connected to the base welding plate 31.

[0033] The upper clamping assembly 22 includes a corner cylinder 221, a base flange locking block 222, and an anti-tilting pressure column 223. The outer shell of the corner cylinder 221 is fixedly connected to the base welded base plate 31. The output end of the corner cylinder 221 is fixedly connected to the middle of the base flange locking block 222. The anti-tilting pressure column 223 is fixedly connected to the end of the base flange locking block 222 away from the inner support ring 112 of the base. The end of the base flange locking block 222 near the inner support ring 112 of the base is used to clamp the base flange 5. The corner cylinder 221 is a mature existing technology and will not be described in detail here.

[0034] When the base flange locking block 222 moves to the lowest position to press the base flange 5, the included angle between the oil nozzle positioning baffle 12 and the two adjacent sets of base flange locking blocks 222 is 45°.

[0035] The base flange locking block 222 has a clamping groove 224 for fitting and clamping the base flange 5 at one end near the inner support ring 112 of the base.

[0036] The lower end of the anti-warping pressure column 223 is covered with a silicone soft layer. When the base flange locking block 222 moves down to the lowest position, the lower end of the anti-warping pressure column 223 abuts against the base welded base plate 31.

[0037] In this utility model, the base flange 5 is positioned on the base welding plate 31 using four sets of positioning pins 21. Then, the motor base 4 is placed on the base flange 5. Rotating the motor base 4 rotates the oil nozzle 41 to the rear side wall of the oil nozzle positioning baffle 12. The pneumatic chuck 111 on the welding plate support 32 located at the lower end of the equal-height pin 33 is activated, causing the chuck's claws to move outwards, pushing the inner support ring 112 of the base outwards until it supports the motor base 4 in place. This provides both fixation and... To achieve concentric positioning, the corner cylinder 221 is activated. The corner cylinder 221 first rotates to the radial position and then moves downward, causing the clamping groove 224 on the machine base flange locking block 222 to press down on the machine base flange 5. The downward movement of the machine base flange locking block 222 causes the anti-tilting pressure column 223 to move down. When the clamping groove 224 presses down on the machine base flange 5, the lower end of the anti-tilting pressure column 223 abuts against the machine base welded base plate 31, which plays an anti-tilting role. The four sets of machine base flange locking blocks 222 simultaneously press down on the machine base flange 5, which further improves the stability of the fixed tooling.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
