Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a steel sheet welding device for producing motor housings. Background Technology

[0002] It's common and normal for motors to generate heat during operation, especially high-power motors, because the resistance generated during current conduction is converted into heat. Therefore, the motor casing needs to be fitted with multiple heat dissipation metal strips to increase the heat dissipation area and help cool the motor.

[0003] Installing steel bars is basically the last step in shell production. Operators will use steel bars of appropriate length to place on the outer wall of the shell. The outer wall of the shell can be marked in advance to help operators position the steel bars. However, this operation cannot install steel bars in batches, and the accuracy of manual positioning is not enough, so work efficiency and quality cannot be guaranteed. Utility Model Content

[0004] The purpose of this application is to provide a steel sheet welding device for producing motor housings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A steel sheet welding device for producing motor housings includes a worktable and two positioning components symmetrically mounted on the worktable. Each positioning component includes a balance bar, a screw, and a mounting block. The two balance bars are symmetrically mounted on one side of the worktable. A cylinder is movably mounted on one end of each balance bar. The mounting block is fixedly mounted on the output end of the cylinder. The screw is mounted on the worktable surface via a bearing. A threaded tube is fixedly mounted on one side of the outer wall of the balance bar, and the threaded tube is threaded onto the outside of the screw. The mounting block is arc-shaped, and multiple fitting grooves are formed on one side of the arc surface of the mounting block.

[0007] Preferably, sleeve one and sleeve three are fixedly installed on the workbench surface, sleeve one and sleeve three are vertically fixed on the workbench surface, and movable rod one is fixedly installed at the bottom of the end of the balance bar away from cylinder two, and movable rod one is fitted inside sleeve one.

[0008] Preferably, a sleeve two is fixedly installed at one end of the balance bar near the cylinder two, and a movable rod two is fixedly installed on one outer wall of the cylinder two, with the movable rod two embedded inside the sleeve two. A movable rod three is fixedly installed at the bottom of the cylinder two, with the movable rod three embedded inside the sleeve three. A cylinder one is provided on one outer side of the sleeve three, and the output end of the cylinder one is fixedly connected to the outer wall of the sleeve three.

[0009] The beneficial effects of this utility model are: by setting a positioning component, the screw adjusts the balance bar longitudinally, and the cylinder adjusts the balance bar laterally. The balance bar drives the steel bar on the mounting block to be quickly positioned, so that the steel bar fits against the outer wall of the motor housing, thereby improving work efficiency.

[0015] like Figure 1-3 The illustrated steel sheet welding device for producing motor housings includes a worktable 1 and two positioning components symmetrically mounted on the worktable 1. Each positioning component includes a balance bar 2, a screw 5, and a mounting block 12. The two balance bars 2 are symmetrically mounted on one side of the worktable 1. A cylinder 7 is movably mounted on one end of the balance bar 2. The mounting block 12 is fixedly mounted on the output end of the cylinder 7. The screw 5 is mounted on the table surface of the worktable 1 via a bearing. A threaded pipe is fixedly mounted on one side of the outer wall of the balance bar 2. The threaded pipe is threaded onto the outside of the screw 5. The mounting block 12 is arc-shaped, and multiple fitting grooves are opened on one side of the arc surface of the mounting block 12.

[0016] On the workbench 1, sleeve 1 3 and sleeve 3 10 are fixedly installed. Sleeve 1 3 and sleeve 3 10 are vertically fixed on the workbench 1. At the bottom of the balance bar 2 away from cylinder 2 7, movable rod 1 4 is fixedly installed. Movable rod 1 4 is fitted into sleeve 1 3.

[0017] A sleeve 2 8 is fixedly installed at one end of the balance bar 2 near the cylinder 2 7. A movable rod 2 9 is fixedly installed on one outer wall of the cylinder 2 7, and the movable rod 2 9 is embedded inside the sleeve 2 8. A movable rod 3 11 is fixedly installed at the bottom of the cylinder 2 7, and the movable rod 3 11 is embedded inside the sleeve 3 10. A cylinder 1 6 is provided on one outer side of the sleeve 3 10, and the output end of the cylinder 1 6 is fixedly connected to the outer wall of the sleeve 3 10.

[0018] Example: Multiple mounting holes are formed on the flat surface of workbench 1. The motor housing is placed on workbench 1, and the bolt holes of the motor housing base align with the mounting holes. The operator uses bolts to fix the motor housing to the workbench 1. The operator selects a suitable mounting block 12 according to the size of the motor housing. Multiple steel strips are embedded in the fitting groove of the mounting block 12. The curvature of the outer wall of the motor housing is matched by the curved surface of the mounting block 12. Then, the screw 5 is rotated, which drives the balance bar 2 to rise and fall. The balance bar 2 drives the movable rod 4 and the movable rod 11 at the bottom of cylinder 7 to slide within sleeve 3 and sleeve 10, respectively. The movable rod 4 and the movable rod 11 guide the balance bar 2. This allows for adjustment of the height of mounting block 12. Then, cylinder 6 is activated, pushing sleeve 3 10, causing cylinder 2 7 to move mounting block 12 laterally. Movable rod 2 9 is driven by cylinder 2 7 and moves inside sleeve 2 8, thus adjusting the position of mounting block 12 so that it aligns with the steel strip mounting point on the motor housing. Cylinder 2 7 then activates, causing the steel strip to fit against the outer wall of the motor housing. The operator can first quickly spot weld the ends of the steel strips to quickly fix multiple steel strips onto the motor housing. Then, cylinder 2 7 drives mounting block 12 to reset, allowing for rapid positioning of the steel strips and one-time alignment with the motor housing, saving positioning time and improving work efficiency.

[0019] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.
