The commutator press-fitting tool 100 comprises a workpiece positioning assembly 110 and a height limiting assembly 120.
The workpiece positioning assembly 110 has a positioning portion 111 for positioning the commutator rotor. The positioning portion 111 may be a hole, a groove, a convex column, a claw structure, etc. Therefore, the workpiece positioning assembly 110 is mainly used for positioning the commutator rotor at a preset position of the working table of the commutator automatic shaft entering machine.
Referring to fig. 2, the height limiting assembly 120 includes a base 121 and a height limiting member 122 disposed on the base 121. The base 121 mainly plays a supporting role, and may be a plate-shaped structure, a block-shaped structure, a frame-shaped structure, a housing, or the like. The height limiting part 122 is used for limiting the working height of the press mounting table in the automatic commutator shaft entering machine. Thus, the height of the height stop 122 is greater than the height of the workpiece positioning assembly 110. The height limiting member 122 may be fixedly connected to the base 121 by welding, screwing, clamping, or the like.
The base 121 has a mounting hole 1211. Wherein, the edge shape of the radial cross section of the mounting through-hole 1211 may be circular, rectangular, polygonal, etc. The workpiece positioning element 110 is disposed through the mounting hole 1211. That is, the base 121 is fitted over the workpiece positioning assembly 110.
For the sake of understanding, the process of press-fitting the commutator by using the commutator press-fitting tool 100 will be briefly described below.
(1) The commutator press-fitting tool 100 is installed on a workbench of an automatic commutator shaft inserting machine, the positioning part 111 is ensured to be aligned with the press-fitting head, and the height limiting part 122 is positioned on one side of the base 121 facing the press-fitting head;
(2) positioning the commutator rotor in the positioning part 111, and clamping the commutator on the press-fitting head to respectively position the commutator rotor and the commutator;
(3) starting the automatic shaft feeding machine of the commutator, driving the press-mounting head to move downwards by the press-mounting table at the moment until the press-mounting table touches the height limiting part 122 to stop moving, so as to limit the working height of the press-mounting table; and then the pressing head drives the commutator to continuously move downwards for a preset distance so as to press the commutator onto the commutator rotor.
Therefore, the height limiting part 122 can realize accurate limiting of the working height of the press-fitting table, the rotating shaft of the commutator rotor is not relied on any more, even if the rotating shaft of the commutator rotor is different in length due to machining errors and other reasons in the part machining process, the press-fitting precision of the commutator can still be ensured by using the commutator press-fitting tool 100.
Referring also to fig. 3, in some embodiments, the workpiece positioning assembly 110 includes a workpiece positioning element 112. The workpiece positioning element 112 has an opposite positioning end 1121 and a fixed end 1122. The positioning portion 111 is a positioning hole opened at the positioning end 1121. The fixed end 1122 is used for fixing with a workbench of the automatic shaft-entering machine of the commutator. When the commutator press-fitting tool 100 is installed on the workbench, the positioning end 1121 and the fixing end 1122 are respectively the upper end and the lower end of the workpiece positioning element 112, at this time, the opening of the positioning hole faces upward, and the fixing end 1122 can be detachably installed on the workbench through screwing, clamping and the like. When the commutator rotor needs to be positioned on the workbench, the commutator rotor only needs to be placed into the positioning hole, and the positioning operation of the commutator rotor is greatly simplified. Moreover, the positioning portion 111 is provided as a positioning hole, which simplifies the machining of the workpiece positioning member 112.
Further, in some embodiments, the end surface of the positioning end 1121 is provided with two finger slots 1123 communicating with the positioning hole. Two finger slots 1123 are oppositely disposed. Specifically, two finger slots 1123 are aligned in a horizontal direction.
In the practical use process, after the commutator is pressed and assembled, the fingers of an operator can penetrate through the finger slots 1123 and stretch into the positioning holes to grasp the commutator rotor, so that the commutator rotor can be conveniently taken out of the positioning holes, the depth of the positioning holes can be set to be deeper, the stability of the commutator rotor in the positioning holes is ensured, the probability of shaking and the like of the commutator rotor in the commutator pressing and assembling process is reduced, and the commutator pressing and assembling precision is further improved. Therefore, due to the arrangement of the finger slots 1123, the commutator press-fitting tool 100 can ensure that the commutator rotor is conveniently taken and placed into the positioning holes, and the press-fitting precision of the commutator is further improved.

The workpiece positioning assembly 110 further includes a circumferential stop 113. The circumferential limiting member 113 is mounted in the mounting groove 1124. One side of the circumferential limiting member 113 extends into the positioning hole and is used for abutting against the side wall of the rotor core of the commutator rotor.
When the commutator rotor is positioned in the positioning hole, one end of the circumferential limiting piece 113 extending into the positioning hole abuts against the side wall of the rotor core of the commutator rotor, so that the probability of the commutator rotor rotating in the commutator press-fitting process is reduced, and the press-fitting precision of the commutator press-fitting is further ensured.
Further, in some embodiments, the circumferential position limiter 113 includes an installation portion 1131 installed in the installation groove 1124 and a position limiting spike 1132 disposed on a side of the installation portion 1131 facing the positioning hole. The limiting spike 1132 is used for inserting into a groove on the side wall of the rotor core in the positioning hole. When the commutator rotor is located in the positioning hole, the limiting spine 1132 is inserted into the groove on the side wall of the rotor core, so that the probability of rotation of the commutator rotor in the press fitting process of the commutator is further reduced, and the press fitting precision of the commutator is higher.
Referring again to fig. 2, in some embodiments, the base 121 is a plate-shaped structure having a ring shape. The base 121 is hollow on the workpiece positioning assembly 110. The empty sleeve means that a certain component is sleeved on another component and is in clearance fit with the other component, and the two components are not fixedly connected with each other, so that a direct action relationship does not exist between the certain component and the other component. Thus, there is no direct operative relationship between the base 121 and the workpiece positioning assembly 110, and the base 121 is free to rotate relative to the workpiece positioning assembly 110.
In one embodiment of the present invention, the height limiting member 122 is a limiting rod. Wherein, the limiting rod can be a round rod, a rectangular rod, a triangular rod, an oval rod and the like. One end of the limiting rod is fixedly connected with the base 121, and the other end of the limiting rod is used for limiting the working height of the press mounting table when the limiting rod touches the press mounting table.

In the part processing, a plurality of base materials are of rod-shaped structures, so that the limiting rod can be processed by only needing few processing procedures, the processing process of the commutator press-fitting tool 100 is greatly simplified, the material waste is reduced, and the processing cost of the commutator press-fitting tool 100 is favorably reduced.
Specifically, the limiting rod is a plurality of. A plurality of stopper rods are provided at intervals in the circumferential direction of the mounting through-hole 1211. More specifically, a plurality of stopper rods are uniformly arranged along the circumferential direction of the mounting through-hole 1211. The arrangement of the limiting rods can improve the reliability of limiting the working height of the press mounting table and also improve the stability of the press mounting table at the working height.
In another embodiment of the present invention, the height limiting member 122 is a positioning plate extending along the circumferential direction of the mounting through hole 1211. The positioning plate may be an arc-shaped plate extending along the circumferential direction of the mounting through hole 1211, or may be a sleeve-shaped structure disposed along the circumferential direction of the mounting through hole 1211. Therefore, the height limiting part 122 is set as a positioning plate, the contact area between the height limiting part 122 and the press mounting table can be increased, the sensitivity of height limiting of the press mounting table can be improved, and meanwhile, the stability of the press mounting table at the working height can be improved.
Specifically, the locating plate is a plurality of. A plurality of positioning plates are provided at intervals in the circumferential direction of the mounting through-hole 1211. Thus, each positioning plate is an arc-shaped plate. And set up the locating plate into a plurality ofly, can be when guaranteeing to carry on spacing comparatively sensitive to pressure equipment platform operating height, still be favorable to the control of processing cost.
It should be understood that, in other embodiments, the height limiting member 122 may also be a spherical structure, a block structure, a flat structure, or the like, as long as the height limiting member can limit the working height of the press-fitting table.
