Description

Technical Field

[0001] The utility model relates to the field of sorting equipment, in particular to a micro bearing sorting device. Background Technique

[0002] The main function of a bearing is to support a rotating mechanical body. Among them, micro bearings are applicable to various fields with high rotational speeds and low noise, such as various industrial equipment and small rotary motors, to reduce the friction coefficient during their movement and ensure their rotational accuracy. After the bearings are produced, corresponding bearing sorting equipment will be used on the production line to classify batches of bearings as good or bad and pick out the bearings that do not meet the standards.

[0003] According to the patent document: CN212821205U, a bearing outer ring sorting device is disclosed, which includes a base, a sorting seat, a positioning component, and a detection component. The detection component includes a bracket, a lifting cylinder, a sliding block, a floating detection head, a sliding groove, an elastic member, a go gauge, a no-go gauge, an upper proximity switch, a lower proximity switch, and an induction block. The beneficial effect of the utility model is that the lifting cylinder in the detection component drives the floating detection head to move downward, so that the go gauge and the no-go gauge are inserted into and detected the inner hole of the bearing outer ring. The external controller receives the signals fed back by the upper proximity switch and the lower proximity switch. Only when the upper proximity switch generates an induction signal and the lower proximity switch does not generate an induction signal, the controller determines that the inner hole size of the bearing outer ring is qualified. Otherwise, the controller controls the external alarm device to start and generate an alarm signal, and the operator takes out the unqualified bearing outer ring. Compared with the existing detection method, the detection efficiency is improved.

[0004] At present, traditional micro bearing sorting devices are mainly applied on sorting racks. Among them, bearing parts are sent from the limited material area on the material feeding rack to the automatic sorting mechanism through a conveying channel, and the bearings conveyed to it are sorted. When the bearings are batch-conveyed to the conveying rack, there is no guiding structure, so as to avoid directly pouring the bearings in batches on the material feeding rack and causing the problem of falling outside when feeding them into the area rack.

In order to guide the bearing parts and avoid offset and the problem of falling outwards when directly poured on the feeding frame, a limited material area frame 102 is installed on the feeding frame 101. A conveyor 103 is arranged between the limited material area frame 102 and the automatic sorting mechanism 104, and a discharging assembly is arranged between the limited material area frame 102 and the feeding frame 101;

[0030] The feeding component includes a feeding frame 105, which is arranged above the end of the material limiting area frame 102. A feeding channel 106 is installed at the bottom opening of the feeding frame 105. A feeding port 107 is formed on one side inside the material limiting area frame 102, and the other end of the feeding channel 106 is in a fitting state with the outer opening of the feeding port 107. An opening frame 110 is installed at the top of the material limiting area frame 102. An outer sleeve frame 108 is installed above the feeding channel 106 close to the material limiting area frame 102, and the other end of the outer sleeve frame 108 is sleeved outside the opening frame 110. The opening frame 110 is installed on the material limiting area frame 102. Under the action of the elastic force of the compression spring 112, the movable block 111 is pressed against the inner side wall of the opening frame 110, driving the clamping rod 114 to penetrate through the opening frame 110 and be inserted into the opening hole 109 to complete the overall installation of the feeding frame 105. During feeding, the material is poured into the feeding frame 105 through the opening, and flows through the feeding channel 106 and the feeding port 107 to the conveying frame 101, so as to guide the bearing parts during the feeding process and avoid the problems of deviation and falling out when directly pouring onto the conveying frame.

[0031] Please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 and Figure 10, in order to disassemble and assemble the outer frame 108 and the opening frame 110, the opening frame 110 and the outer frame 108 are connected by a fixing structure. The fixing structure includes two groups of movable blocks 111. The two groups of movable blocks 111 are symmetrically and movably installed at the front and rear ends inside the opening frame 110. An extrusion spring 112 is arranged between the two groups of movable blocks 111. Corresponding clamping rods 114 are installed at the ends of the two groups of movable blocks 111 facing away from each other. Through holes 109 are opened at the front and rear ends inside the opening frame 110, and the other ends of the clamping rods 114 penetrate through the opening frame 110 and are inserted into the corresponding through holes 109; the outer frame 108 is designed in a U shape, and corresponding moving handles 113 are installed at the tops of the movable blocks 111; a pressing member 116 is installed at the lower end of the outer opening of the material discharge port 107, and the other end of the pressing member 116 is in a state of being in mutual contact with the bottom of the material discharge channel 106; the material discharge channel 106 is designed in a slope shape, and the end of the pressing member 116 close to the material discharge channel 106 is designed with a rubber material; if the moving handles 113 at the front and rear ends are moved towards each other, under the acting force, the movable blocks 111 can be driven to move towards each other. When the movable blocks 111 move inside the opening frame 110, the extrusion spring 112 is extruded, and the clamping rods 114 are pulled out of the inserted state inside the through holes 109. After being inside the opening frame 110, the whole movable blocks 111 can be moved out of the opening frame 110, so that the whole outer frame 108 is in a movable state. At this time, when the whole material discharge channel 106 is pulled outwards, the outer frame 108 is taken out of the sleeved state outside the opening frame 110, and the whole structure on the material discharge channel 106 can be disassembled; when the material discharge channel 106 is aligned with the outer opening of the material discharge port 107, the pressing member 116 is installed outside the material limiting area frame 102, and the rubber material end is in a state of being in contact with the bottom of the material discharge channel 106 to press the bottom to ensure the stability of the bottom connection.

[0032] Please refer to Figure 2 , Figure 4 , Figure 7 and Figure 8, after most wires are clamped in the corresponding wire openings 201 from top to bottom, a wire assembly is provided on the sorting table frame 1 for sorting the wires. The wire assembly includes a wire plate 2, which is arranged at one end of the sorting table frame 1. Multiple groups of wire openings 201 are formed inside the wire plate 2. A movable frame 202 is arranged below the wire plate 2. A sliding rod 208 is installed on the inner wall of the movable frame 202, and a sleeve 203 is slidably connected to the sliding rod 208. A support rod 204 is installed at the top of the sleeve 203, and the other end of the support rod 204 is glued to the middle of the bottom end of the wire plate 2. Outer plates 206 are installed on both sides at the front end of the outer wall of the movable frame 202. Two sets of sleeve rods 207 are installed on the top of the sorting table frame 1, and the other end of the outer plate 206 is sleeved on the corresponding sleeve rod 207; an inner lining cylinder 205 is glued to the inner circle of the sleeve 203, and the other end of the inner lining cylinder 205 is in a state of mutual fit with the outer wall of the sliding rod 208; by arranging the wire plate 2 at the front end of the automatic sorting mechanism 104, the position of the wire plate 2 on the movable frame 202 can be changed by moving the wire plate 2 back and forth. At the same time, the outer plate 206 is connected to the movable frame 202, and the sleeve rod 207 is installed on the sorting table frame 1. At this time, after the outer plate 206 is sleeved outside the sleeve rod 207, the overall positioning of the movable frame 202 is carried out, which is also convenient for the subsequent separation of the whole movable frame 202 from the sorting table frame 1. Multiple groups of wire openings 201 are formed on the wire plate 2. The wire plate 2 is elastic. When applying cables on the sorting table frame 1, after most wires are clamped in the corresponding wire openings 201 from top to bottom, the wires can be sorted to avoid clutter. An inner lining cylinder 205 made of rubber is glued to the inner circle of the sleeve 203. After the sleeve 203 is moved, a certain frictional force is generated between it and the outer wall of the sliding rod 208 to position the moved sleeve 203.

[0033] Working principle: First, the current traditional micro-bearing sorting device is mainly a sorting device composed of a sorting bench 1, a feeding rack 101, a material-limiting area rack 102, a conveying channel 103, an automatic sorting mechanism 104 and other structures. During sorting, the materials are placed upside down on the feeding rack 101 and within the material-limiting area rack 102, and are moved by the conveyor belt to the conveying channel 103 and then conveyed onto the automatic sorting mechanism 104. An induction detection head is provided inside the inlet of the automatic sorting mechanism 104 to sort the bearings that do not meet the standards. At this time, when the materials are poured onto the feeding rack 101, a feeding frame 105 is provided at the outer end of the material-limiting area rack 102. The feeding frame 105 and the blanking channel 106 are designed as an integrated structure, and the blanking channel 106 corresponds to the outer opening of the blanking port 107. The outer sleeve frame 108 and the blanking channel 106 are designed as an integrated structure. The opening frame 110 is installed on the material-limiting area rack 102. Under the action of the elastic force of the compression spring 112, the movable block 111 is pressed against the inner side wall of the opening frame 110, driving the clamping rod 114 to pass through the opening frame 110 and be inserted into the opening hole 109 to complete the installation of the entire feeding frame 105. During blanking, just pour from the feeding frame 105, and it flows through the blanking port 107 of the blanking channel 106 onto the feeding rack 101. During the blanking process, the bearing parts are guided to avoid problems such as deviation and falling outward when directly poured onto the feeding rack. If the moving handles 113 at the front and rear ends are moved towards the end close to each other, under the acting force, the movable block 111 can be driven to move towards the end close to each other. When the movable block 111 moves inside the opening frame 110, the compression spring 112 is compressed, and the clamping rod 114 is withdrawn from the inserted state inside the opening hole 109. After it is inside the opening frame 110, the entire movable block 111 can be moved out of the opening frame 110, making the entire outer sleeve frame 108 in a movable state. At this time, when the blanking channel 106 is pulled out as a whole, the outer sleeve frame 108 is taken out of the sleeved state outside the opening frame 110, and the overall structure on the blanking channel 106 can be disassembled;

[0034] The wire board 2 is arranged at the front end of the automatic sorting mechanism 104. The sleeve 203 is slidably connected to the slide bar 208. The inner lining cylinder 205 is connected to the wire board 2 through the support rod 204. By moving the wire board 2 back and forth, the position of the wire board 2 on the movable frame 202 can be changed. At the same time, the outer jacket plate 206 is connected to the movable frame 202, and the sleeve rod 207 is installed on the sorting bench 1. After the outer jacket plate 206 is sleeved outside the sleeve rod 207 at this time, the whole movable frame 202 is positioned, which is also convenient for the subsequent separation of the whole movable frame 202 from the sorting bench 1. A plurality of wire ports 201 are provided on the wire board 2. The wire board 2 is elastic. When applying cables on the sorting bench 1, after most of the wires are clamped in the corresponding wire ports 201 from top to bottom, the wires are sorted to avoid clutter. The above is the working process of the whole device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
