Description

Technical Field

[0001] This utility model relates to the field of commutator production technology, specifically to a metal commutator angle adjustment mechanism. Background Technology

[0002] The commutator is a major component of an electric motor. It mainly consists of an inner bushing, a bakelite body surrounding the inner bushing, and copper busbars with commutator segments arranged around the bakelite body. The commutator segments are usually made of copper.

[0003] Existing technology typically uses stamping dies for commutator segment processing. After stamping the metal strip, it needs to be bent to form the product. Existing devices usually have an angled opening on the stamping head to facilitate bending of the stamped metal strip. The bending angle is fixed, and when adjusting the angle, the stamping head needs to be replaced, which reduces production efficiency. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] A metal commutator angle adjustment mechanism, through the cooperation of an adjustment punch and a pressure plate, can adjust the distance between two adjustment punches. It is suitable for metal strips of different sizes within a certain range. At the same time, the pressure plate is detachably set at the end of the adjustment punch, and can be removed or added according to production needs to assist in adjusting the slope angle of the adjustment punch without replacing the adjustment punch, thereby improving production efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-3As shown, this utility model provides a technical solution: a metal commutator angle adjustment mechanism, including a support component 1, the support component 1 including a body 101, and a stamping component 3, the stamping component 3 including a hydraulic cylinder 307, the hydraulic cylinder 307 being fixed below the body 101, a template 305 being fixed to the end of the hydraulic cylinder 307, a sliding groove 306 being provided inside the template 305, two adjusting blocks 302 being slidably arranged inside the sliding groove 306, an adjusting punch 303 being fixed below each of the two adjusting blocks 302, a screw 301 being provided at both ends of the template 305, the end of the screw 301 being rotatably mounted on the adjusting block 302, and a clamping component 2 being provided on the body 101.

[0020] It should be noted that when the screw 301 is rotated, the screw 301 drives the adjusting block 302 to slide inside the sliding groove 306. The adjusting block 302 drives the adjusting punch 303 to move, thereby adjusting the distance between the two adjusting punches 303. This method is suitable for metal strips of different sizes within a certain range.

[0021] A base 105 is fixed to the bottom of the body 101, and a mounting plate 102 is fixed on the body 101. A support plate 104 is fixed between the mounting plate 102 and the base 105. A limit groove 103 and a limit hole 106 are provided on the mounting plate 102.

[0022] It should be noted that the limiting groove 103 and the limiting hole 106 can help limit the position of the metal strip, making it convenient for stamping and bending.

[0023] The two adjusting punches 303 are symmetrical to each other, and the ends of the two adjusting punches 303 are provided with inclined surfaces. Several pressure adjusting plates 304 are provided at the ends of the adjusting punches 303.

[0024] It should be noted that several pressure regulating plates 304 are detachably installed at the end of the adjusting punch 303. They can be removed or added according to production needs to assist in adjusting the slope angle of the adjusting punch 303 without replacing the adjusting punch 303, thereby improving production efficiency.

[0025] The clamping assembly 2 includes a limiting post 201, which is slidably disposed on the limiting hole 106. A lifting block 206 is fixed above the limiting post 201. One end of the lifting block 206 abuts against the machine body 101. A pressing block 202 is provided at the other end of the lifting block 206. A limiting block 203 is fixed below the pressing block 202. The limiting block 203 is located directly above the limiting groove 103.

[0026] It should be noted that the pressure block 202 is detachably set at the end of the limiting post 201, so that it can be replaced as needed to fix and limit the metal strip. Both sides of the pressure block 202 are chamfered, which makes it easier to press the metal strip to the appropriate angle and avoids the metal strip from twisting during the pressing process, thus reducing the probability of defective products.

[0027] The clamping assembly 2 also includes a fixing plate 204 and a lifting motor 207. The fixing plate 204 is fixed on the machine body 101, and the lifting motor 207 is fixed below the mounting plate 102. The threaded rod 205 is rotatably mounted on the mounting plate 102 and the fixing plate 204. The output shaft of the lifting motor 207 is connected to the threaded rod 205 through a coupling, and the lifting block 206 is threadedly connected to the threaded rod 205.

[0028] It should be noted that the lifting motor 207 drives the threaded rod 205 to rotate through the output shaft. The threaded rod 205 drives the lifting block 206 to move. The lifting block 206 drives the pressing block 202 to move. The pressing block 202 squeezes and limits the metal strip, which facilitates the stamping and bending of the metal strip.
