Feeding mechanism of stator paper inserting machine

Abstract

The utility model discloses a feeding mechanism of a stator paper inserting machine. The feeding mechanism comprises a feeding device, an upper positioning assembly and a lower positioning assembly. According to the feeding mechanism of the stator paper inserting machine, after the hoisting conveying position of a stator workpiece is positioned by the lower clamping block and the side positioning block on the conveying frame, the auxiliary conical blocks at the bottoms of the positioning insertion blocks on the two sides of the bottom of the clamping seat can be firstly inserted into insertion holes in the stator workpiece through fine structures at the lower ends of the auxiliary conical blocks; and meanwhile, the positioning seats on the two sides of the positioning plate can also rotate the positioning rods on the two sides of the clamping seats through the positioning motors so as to position the feeding installation position of the stator workpiece at the bottom of the clamping seats, and therefore the stator workpiece can be accurately positioned. Therefore, through a three-layer positioning structure for the hoisting conveying position, the clamping position and the feeding mounting position of the stator workpiece, the positioning accuracy in the feeding process of the stator workpiece is improved.

Description

Technical Field

[0001] This utility model relates to the field of stator paper insertion machine technology, specifically a stator paper insertion machine feeding mechanism. Background Technology

[0002] The stator paper insertion machine is an essential piece of equipment in the motor manufacturing process. It is mainly used to insert insulating paper into the stator slots to prevent electrical insulation failures during motor use. The feeding mechanism of the stator paper insertion machine is an automatic feeding mechanism for stator workpiece processing, thereby improving production efficiency.

[0003] Existing stator feeding mechanisms for paper inserters, such as the stator feeding structure for a vertical stator paper inserter disclosed in CN221467535U, have the advantages of accurately aligning the grooves on the stator with the paper inserting mechanism on the vertical stator paper inserter, resulting in good performance. However, in this feeding structure, the positioning blocks on both sides of the positioning column are not easily and accurately moved into the insertion holes of the stator workpiece during downward movement. Consequently, misalignment between the positioning blocks and the insertion holes in the stator will affect the positioning effect. Therefore, we propose a new stator feeding mechanism for paper inserters. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A stator paper insertion machine feeding mechanism includes: a feeding device, an upper positioning component, and a lower positioning component; the feeding device includes a lower conveyor frame, an upper slide rail frame, a stator workpiece conveyed on the conveyor frame, an insertion hole in the stator workpiece, and a lifting cylinder installed at the bottom of the slide rail frame; the upper positioning component includes a positioning plate fixedly installed at the bottom of the lifting cylinder, a positioning motor fixedly installed at the center of the positioning plate, a reduction motor fixedly installed at the bottom of the positioning motor, a clamp fixedly installed at the bottom of the reduction motor, positioning blocks fixedly installed on both sides of the bottom of the clamp, auxiliary cone blocks fixedly installed at the bottom of the positioning blocks, and pressure sensor blocks fixedly installed at the bottom of the auxiliary cone blocks; the lower positioning component includes a lower positioning cylinder fixedly installed on both sides of one end of the conveyor frame, and a lower clamp block fixedly installed at the inner end of the lower positioning cylinder.

[0007] Preferably, positioning seats are fixedly installed on both sides of the positioning plate, and positioning rods are fixedly installed on both sides of the clamp, and the positioning rods can be matched and installed in the positioning seats.

[0008] Preferably, a processor is also fixedly installed on one side of the upper end of the clamp, and the processor is electrically connected to the geared motor and the pressure sensor block.

[0009] Preferably, a double-headed cylinder is also fixedly installed inside the clamping seat, and upper clamping blocks are fixedly installed on both sides of the double-headed cylinder.

[0010] Preferably, the positioning block matches the insertion hole.

[0011] Preferably, a side positioning block is also fixedly installed at one end of the conveyor frame.

[0012] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0013] 1. In this utility model, after the lower clamping block and the side positioning block on the conveyor frame position the stator workpiece for hoisting and conveying, the auxiliary cone blocks at the bottom of the positioning inserts on both sides of the bottom of the clamping seat can be inserted into the insertion hole in the stator workpiece first through their small structure at the bottom end, and after moving down, they correct the clamping part of the stator workpiece to ensure the accurate positioning of the clamping seat on the stator workpiece. At the same time, the positioning seats on both sides of the positioning plate can also be positioned at the feeding installation position of the stator workpiece at the bottom of the clamping seat by rotating the positioning rods on both sides of the clamping seat through the positioning motor. Thus, the positioning accuracy of the stator workpiece during feeding is improved through the three-layer positioning structure of the hoisting and conveying position, clamping position and feeding installation position of the stator workpiece.

[0014] 2. In this utility model, when the auxiliary cone at the bottom of the positioning insert cannot directly enter the insertion hole in the stator workpiece, the pressure sensor block at the bottom of the auxiliary cone can also be adjusted by the processor through the reduction motor to rotate the clamp and the auxiliary cone on both sides by a small distance during the extrusion process, so that the auxiliary cone can be inserted into the insertion hole and the positioning accuracy is guaranteed during the positioning process.

It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0024] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a stator paper insertion machine feeding mechanism. Example 1

[0025] Combination Figure 1-4 As shown, the present invention provides a stator paper insertion machine feeding mechanism, comprising: a feeding device 100, an upper positioning component 200, and a lower positioning component 300; the feeding device 100 includes a lower conveyor frame 101, an upper slide rail frame 102, a stator workpiece 103 conveyed on the conveyor frame 101, an insertion hole 104 opened in the stator workpiece 103, and a lifting cylinder 105 installed at the bottom of the slide rail frame 102; the upper positioning component 200 includes a positioning plate 201 fixedly installed at the bottom of the lifting cylinder 105, a positioning motor 202 fixedly installed at the center of the positioning plate 201, a reduction motor 203 fixedly installed at the bottom of the positioning motor 202, a clamp 204 fixedly installed at the bottom of the reduction motor 203, positioning blocks 205 fixedly installed on both sides of the bottom of the clamp 204, auxiliary cones 206 fixedly installed at the bottom of the positioning blocks 205, and auxiliary cones 206 fixedly installed on both sides of the bottom of the positioning blocks 205. 06. Pressure sensor blocks 207 are fixedly installed at the bottom; the lower positioning assembly 300 includes a lower positioning cylinder 301 fixedly installed on both sides of one end of the conveyor frame 101, a lower clamping block 302 fixedly installed inside the lower positioning cylinder 301, a positioning seat 208 fixedly installed on both sides of the positioning plate 201, a positioning rod 209 fixedly installed on both sides of the clamping seat 204, and the positioning rod 209 can be matched and installed in the positioning seat 208, a processor 210 fixedly installed on one side of the upper end of the clamping seat 204, and the processor 210 is electrically connected to the reduction motor 203 and the pressure sensor block 207, a double-headed cylinder 211 fixedly installed inside the clamping seat 204, an upper clamping block 212 fixedly installed on both sides of the double-headed cylinder 211, a positioning insert 205 matching the insert hole 104, and a side positioning block 303 fixedly installed at one end of the conveyor frame 101.

[0026] Specifically, the stator paper insertion machine is an essential piece of equipment in the motor manufacturing process. It is mainly used to insert insulating paper into the stator slots to prevent electrical insulation failures during motor operation. The feeding mechanism of the stator paper insertion machine is an automatic feeding mechanism for the stator workpiece 103. In this feeding device 100, after the lower clamping block 302 and side positioning block 303 on the conveyor frame 101 are positioned for the hoisting and conveying of the stator workpiece 103, the auxiliary cone blocks 206 at the bottom of the positioning insertion blocks 205 on both sides of the bottom of the clamping seat 204 can, through their small lower structures, first insert into the insertion holes 104 in the stator workpiece 103, and after moving downwards, correct the clamping position on the stator workpiece 103 to ensure accurate positioning of the clamping seat 204 on the stator workpiece 103. Simultaneously, the positioning seats 208 on both sides of the positioning plate 201 can also, through the positioning motor 202, position the positioning rods 209 on both sides of the clamping seat 204. The rotation of the clamping block 204 is used to position the stator workpiece 103 at the bottom of the clamping block 204 for feeding and installation. This three-layer positioning structure, which includes the hoisting and conveying position, clamping position, and feeding and installation position of the stator workpiece 103, improves the positioning accuracy of the stator workpiece 103 during feeding. At the same time, when the auxiliary cone block 206 at the bottom of the positioning block 205 cannot directly enter the insertion hole 104 in the stator workpiece 103, the pressure sensor block 207 at the bottom of the auxiliary cone block 206 can also be adjusted by the processor 210 through the control of the reduction motor 203 to rotate the clamping block 204 and the auxiliary cone blocks 206 on both sides by a small distance, so that the auxiliary cone block 206 can be inserted into the insertion hole 104, ensuring the positioning accuracy during the positioning process. The upper clamping blocks 212 installed on both sides of the double-headed cylinder 211 in the clamping block 204 are mainly used for clamping and fixing the stator workpiece 103 after the clamping position is positioned.

[0027] Working principle and usage process of this utility model:

[0028] During transport, the stator workpiece 103 at the upper end of the conveyor frame 101 will move to the inner end of the side positioning block 303, and the lower clamping block 302 driven by the lower positioning cylinders 301 on both sides of the side positioning block 303 will complete the positioning of the stator workpiece 103 at the upper end of the conveyor frame 101. After the stator workpiece 103 is positioned, the lifting cylinder 105 at the bottom of the slide rail frame 102 will be activated to drive the clamping seat 204 at its bottom to move down. During the downward movement of 204, the auxiliary cones 206 at the bottom of the positioning blocks 205 on both sides of the clamping seat 204 will penetrate into the insertion holes 104 on both sides of the stator workpiece 103 through their small bottom parts. As the movement continues downward, the upper positioning blocks 205 are positioned and inserted into the insertion holes 104 on both sides of the stator workpiece 103, thus completing the positioning of the stator workpiece 103. Then, the double-headed cylinder 211 inside the clamping seat 204 is activated to move the upper cylinder through its two ends. The clamping block 212 clamps and fixes the stator workpiece 103. After the stator workpiece 103 is clamped and positioned by the clamping seat 204, the positioning motor 202 on the top of the reduction motor 203 can be started to rotate the clamping seat 204 as a whole, so that the positioning rods 209 on both sides of the upper end of the clamping seat 204 are positioned in the positioning seats 208 at both ends, thereby completing the positioning of the feeding position of the stator workpiece 103. At this time, the stator workpiece 103 can be accurately fed by the lifting cylinder 105 and the slide rail frame 102. When the auxiliary cone block 206 at the bottom of the positioning insert 205 is blocked when it moves into the insertion hole 104, the pressure sensor block 207 at the bottom of the auxiliary cone block 206 can also transmit an electrical signal to the processor 210 during the extrusion, so that the processor 210 can remotely control the reduction motor 203 to rotate the auxiliary cone block 206 slightly, so as to better enter the insertion holes 104 on both sides of the stator workpiece 103.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
