Description

Technical Field

[0001] This utility model belongs to the technical field of commutator production equipment, and in particular relates to a stamping device for commutator production. Background Technology

[0002] A commutator is a component in a DC permanent magnet series motor that enables the motor to rotate continuously. Therefore, the commutator is an important component for the continuous rotation of the motor. It enables the motor to rotate continuously by changing the direction of the current in the motor. Stamping equipment is required in the production of commutators. The stamping equipment uses pressure and molds to plastically deform the object, thereby obtaining a workpiece of the required shape and size.

[0003] Traditional stamping equipment used for commutators has many limitations: First, it has poor adaptability. The fixed device on the stamping equipment has a fixed size and can only be adapted to a single specification of commutator. When changing to different sizes of products, the tooling needs to be readjusted or replaced, which is time-consuming and labor-intensive. Second, it has low production efficiency. It is mostly a single-station operation. Workpieces cannot be loaded and unloaded simultaneously during stamping. It requires manual access to the stamping area to pick up the parts, which poses a safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a stamping equipment for commutator production to solve problems such as poor adaptability, fixed size of the fixing device on the stamping equipment, and the inability to adapt to only a single specification of commutator.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: It includes an operating table, on both sides of the operating table, two movable plates are symmetrically arranged. Several base plates are equidistantly arranged above the movable plates. Each base plate has a fixing device on its side and a placement groove on its top. Two limiting plates are symmetrically arranged inside the placement groove. Springs are provided on the opposite sides of the limiting plates. Connecting blocks are provided on the opposite sides of the movable plates. Electric cylinders are provided on the sides of the connecting blocks. Connecting plates are located below the electric cylinders. A controller is provided at one end of the operating table. Two first sliders are symmetrically arranged below the movable plate on the side away from the controller. Two second sliders are symmetrically arranged below the movable plate on the side closer to the controller. Two first sliding grooves are symmetrically arranged on the upper surface of the operating table. Second sliding grooves are provided on the opposite sides of the first sliding grooves. First connecting columns are provided above both ends of the operating table. A second connecting column is provided between the upper ends of the two first connecting columns. Several stamping machines are equidistantly arranged below the second connecting columns.

[0006] Furthermore, the fixing device includes a threaded column, with movable blocks at both ends of the threaded column, a fixed plate on the side of each movable block near the base plate, and nuts movably connected to the sides of each movable block that are far apart from each other. A fixed block is provided at one end of the threaded column, and a circular groove is passed through the side of each movable block.

[0007] Furthermore, the fixing block is connected to the base plate, the threaded column is movably connected inside the circular groove and the two are of the same size, and the fixing plate is movably connected to the upper surface of the base plate and the two are of the same length.

[0008] Furthermore, the threaded post is movably connected inside the nut and the two are of the same size, the fixing plate is movably connected above the limiting plate, and the limiting plate is movably connected inside the placement groove and the two are of the same height.

[0009] Furthermore, the spring is connected between the limiting plate and the placement groove, and the connecting plate is connected to the operating table.

[0010] Furthermore, the first slider is movably connected inside the first groove and the two are of the same size, and the second slider is movably connected inside the second groove and the two are of the same size.

[0011] Furthermore, the first slide groove and the second slide groove have the same length, and the sum of the lengths of the second connecting column and the base plate is the same as the length of the first slide groove.

[0012] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0013] 1. The limiting plate placed in the slot can automatically adapt to the two ends of the commutator of different sizes through the spring force. With the adjustment of the threaded column and nut of the fixing device, the fixing plate can accurately clamp the lower two sides of the workpiece, realize the stable fixing of commutators of different specifications, without the need to change the tooling, and has a high range of compatibility.

[0014] 2. The two movable plates are driven by electric cylinders and move horizontally with the help of the cooperation of sliders and slides. They can move alternately to the bottom of the press for operation. When one side is being pressed, the other side can simultaneously complete the loading and unloading of workpieces, eliminating equipment idle time and improving production efficiency.

[0015] 3. The workpiece is loaded and unloaded on a movable plate away from the stamping area. The workpiece is driven in and out of the stamping station by an electric cylinder, avoiding direct contact between the workers and the stamping area and protecting the safety of the workers. 4.

[0025] The fixing block 45 is connected to the base plate 3. The threaded column 41 is movably connected inside the circular groove 46 and the two are of the same size. The fixing plate 43 is movably connected to the upper surface of the base plate 3 and the two are of the same length.

[0030] Working principle: In this invention, the two limiting plates 6 inside the placement slot 5 are first moved backward. Then, the commutator is placed between the two limiting plates 6. The spring 7 limits both ends of the commutator. Next, the nut on the fixing device 4 is rotated, causing the movable block 42 to move the fixing plate 43 to both sides of the lower end of the commutator, clamping and fixing it. This allows for commutator position adjustment and can also clamp commutators of different sizes. Then, the controller 11 controls the electric cylinder 8 to drive the movable plate 2 to move horizontally. The first slider and the second slider... The block, in conjunction with the first and second sliding grooves, allows the two movable plates 2 to move directly below the connecting column 17. During the stamping process, one movable plate 2 is first moved directly below the second connecting column 17 so that the commutator is aligned with the stamping machine. Then, the stamping process is carried out. After the stamping process, the electric cylinder 8 drives the commutator on the movable plate 2 to move out of the second connecting column. Then, the fixed commutator on the other side is controlled to move under the stamping machine for operation. This allows for the exchange of commutators on the movable plates 2 for stamping, improving work efficiency and ensuring personnel safety when removing the stamped commutator.
