[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] Referring to the accompanying drawings: This commutator segment production equipment includes a body 1, and also includes

[0026] A commutator segment clamping seat 2 is arranged on the machine body 1, and the commutator segment clamping seat 2 has a loading station and a plurality of clamping stations for clamping the commutator segments to be processed during processing, and each clamping station corresponds to a different forming process; and

[0027] A commutator segment processing seat 3 is arranged on the machine body 1, and the commutator segment processing seat 3 has processing stations matching the number of clamping stations of the commutator segment clamping seat 2, and each processing station is provided with a cutter head 4 corresponding to a different forming process; and

[0029] The commutator segment transposition seat 7 is arranged on the machine body 1. The commutator segment transposition seat 7 is located at the front end of the commutator segment clamping seat 2 and can move along the arrangement direction of the clamping station, so as to transpose the commutator segment that has completed the corresponding molding process to the clamping station of the next molding process. The principle of the utility model is that the commutator segment clamping seat 2 allows the unprocessed commutator segment to be transported to the commutator segment clamping seat 2 through the loading station. There are at least four clamping stations and they are distributed from left to right. The unfinished commutator segment is transposed from the loading station to the corresponding clamping station through the commutator segment transposition seat 7, and the commutator segment is pushed into the clamping station through the commutator segment processing seat 3, and then clamped. After the clamping is completed, the commutator segment processing seat 3 continues to perform molding processing on the clamped commutator segment, and the cutter head 4 in each processing station corresponds to the molding form at different stages, so that the commutator segment obtains the required form in sequence when switching between the clamping stations, and After the cutter head 4 at the processing station located at the right end completes the processing, the lateral processing seat 5 completes the last step of processing of the commutator segment through the lateral cutter head 6, and the lateral processing seat 5 and the cutter head 4 at the processing station located at the right end process the commutator segment synchronously, thereby obtaining the commutator segment in the form of a finished product. At the same time, during the processing of the commutator segment, each clamping station clamps the commutator segment, so that at least 4 commutator segments can be processed at the same time during one processing action of the commutator segment processing seat 3, and the number of commutator segments processed at one time is determined according to the number of times required for processing. Therefore, the equipment can realize the processing of an entire commutator segment, and realize continuous automatic processing, which is convenient and fast.

[0030] The commutator segment clamping seat 2 includes a first seat body 21 and a plurality of clamping dies 22 used as clamping stations. The first seat body 21 is provided with a clamping die mounting hole 21-a matching the clamping die 22. The clamping die 22 is provided with a first clamping block 22-a and an ejector 22-b that can be retracted under compression. The first clamping block 22-a is used to clamp the front section of the commutator segment. The ejector 22-b is located at the rear end of the first clamping block 22-a and allows the first clamping block 22-a to be retracted. During extrusion, the commutator segment is pushed away from the first clamping block 22-a. The first seat body 21 can be provided with all the clamping molds 22 at the same time. The clamping mold 22 clamps the commutator segment through the first clamping block 22-a. The ejector 22-b ejects the commutator segment out of the first clamping block 22-a, that is, ejects the clamping mold 22, so that it is convenient for the commutator segment transposition seat 7 to clamp the commutator segment, and then the position transposition is realized by moving the commutator segment transposition seat 7.

[0031] The ejector 22-b includes an ejector rod 22-b1, a rod seat 22-b2, and a first spring 22-b3. The ejector rod 22-b1 and the rod seat 22-b2 are integrally formed. The ejector rod 22-b1 is always kept in the clamping mold 22. The rod seat 22-b2 is partially kept in the clamping mold 22 in the non-ejection state and completely kept in the clamping mold 22 in the ejection state. The first spring 22-b3 is always kept in the clamping mold 22 and one end abuts against the first clamping block 22-a and the other end abuts against the rod seat 22-b2. That is, the commutator segment is ejected by the ejector rod 22-b1. The rod seat 22-b2 is used to abut against the first spring 2 2-b3 is in contact with the cylinder as a power source. Because the outer diameter of the rod seat 22-b2 is larger than the outer diameter of the push rod 22-b1, when it contacts the first spring 22-b3, the outer diameter of the first spring 22-b3 in contact can match the outer diameter of the space provided in the clamping mold 22, so that the first spring 22-b3 will not bend when subjected to force compression, so that the buffering effect of the first spring 22-b3 is good. When contacting with the cylinder, the rod seat 22-b2 can provide sufficient contact area, thereby ensuring contact stability, so that the push rod 22-b1 can quickly respond to ejection.

[0032] The commutator segment processing seat 3 includes a second seat body 31 and a plurality of clamping heads 32 used as processing stations. The second seat body 31 is provided with a clamping head mounting hole 31-a matching the clamping head 32. The clamping head 32 is provided with a second clamping block 32-a and a buffer member 32-b that can be retracted when squeezed. The second clamping block 32-a is used to clamp the cutter head 4. The buffer member 32-b acts on the second clamping block 32-a and allows the cutter head 4 to squeeze and buffer the commutator segment during processing. The second seat body 31 is driven by a crank connecting rod through a gear mechanism. The mechanism realizes reciprocating movement, and all the clamping heads 32 can be set at the same time. The clamping head 32 clamps the tool head 4 through the second clamping block 32-a, and the buffer part 32-b produces a buffering effect when the commutator segment is pushed into the commutator segment clamping seat 2 through the commutator segment processing seat 3, that is, no processing action occurs when the commutator segment is pushed into the commutator segment clamping seat 2. The impact effect of the commutator segment processing seat 3 on the commutator segment is reduced through the buffering effect. The commutator segment is processed only after the commutator segment clamping seat 2 clamps the commutator segment, thereby ensuring the processing effect.

[0033] The buffer member 32-b includes an outer sleeve 32-b1 and a second spring 32-b2. The outer sleeve 32-b1 is always maintained in the clamping head 32 and allows the second clamping block 32-a to be placed inside and move along the length direction of the outer sleeve 32-b1. The second spring 32-b2 is always maintained in the outer sleeve 32-b1 and one end abuts against the second clamping block 32-a and the other end abuts against the inner bottom surface of the outer sleeve 32-b1. The outer sleeve 32-b1 is columnar in configuration and is fixedly arranged in the clamping head 32. It has a channel for the second clamping block 32-a to move inside, and the channel is also used for the second spring 32-b2 to be placed inside. The second spring 32-b2 acts as a buffer during processing and uses its own elastic force to reset the second clamping block 32-a to its initial position during processing, so that no manual intervention is required.

The right side opening 51-a2 allows the output shaft of the cylinder to extend into the clamping block mounting groove 51-a, thereby realizing the connection with the third clamping block 52, and the opening width of the right side opening 51-a2 is smaller than the width of the third clamping block 52, so that the third clamping block 52 can stably exist in the clamping block mounting groove 51-a, and the third clamping block 52 is used to set the lateral cutter head 6, and the lateral cutter head 6 enters into the lateral cutter head mounting groove 51-b through the left side opening 51-b1, and the lateral cutter head mounting groove 51-b is interconnected with the clamping block mounting groove 51-a, so that a part of the lateral cutter head 6 is placed outside the lateral processing seat 5, and a part enters into the clamping block mounting groove 51-a and combines with the third clamping block 52.
