Technical Field

[0001] The utility model relates to the field of bearing installation, in particular to a roller installation tooling for a step-type screw bearing. Background Art

[0002] In the conventional bearing installation field, it is necessary to coat the inner wall of the bearing outer ring with colloid, then install the rollers, and finally install the screws and end caps in sequence;

[0003] Now, there are usually two ways to install screw bearings:

[0004] 1: Through the intermittent transmission of the conveyor belt, when the bearing outer ring is moved to the corresponding installation mechanism, the installation of the corresponding components is realized. However, during the intermittent movement of the bearing outer ring, due to inertia, the positioning is inaccurate;

[0005] 2: Through the uniform movement of the conveyor belt, the uniform movement of the bearing outer ring is driven. However, during the uniform movement, the corresponding installation mechanism also needs to move, increasing the cost;

[0006] In summary, how to realize the installation of rollers in screw bearings has become an urgent problem for researchers in this field to solve. Summary of the Utility Model

[0007] The technical problem to be solved by the utility model is: how to realize the installation of rollers in screw bearings;

[0008] To solve the above technical problem, the technical solution adopted by the utility model is:

[0009] The utility model is a roller installation tooling for a step-type screw bearing, including: a conveying channel; a workbench, which is arranged on one side of the conveying channel and is flush with the conveying channel; a glue injector, which is arranged outside the length side of the workbench; a roller installation machine, which is arranged outside the length side of the workbench and is located on one side of the glue injector; a push plate, which is arranged on the workbench and the conveying channel, and at least two notches are arranged on the length side thereof, and the bottom height thereof is higher than that of the conveying channel; a driving mechanism, which drives the push plate to make a two-axis reciprocating motion, and under the cooperation of the notches, guides the bearing outer ring from the conveying channel to the workbench, and realizes the step-by-step linear motion of the bearing outer ring along the length direction of the workbench on the workbench, and passes under the glue injector and the roller installation machine;

[0010] In this solution, the conveying channel and the working bar are vertically arranged. First, the outer ring of the bearing is placed on the conveying channel. When the outer ring of the bearing moves to the end of the conveying channel, the driving mechanism drives the push plate to move, so that the leftmost notch is engaged with the outer ring of the bearing, and the outer ring of the bearing is transported from the conveying channel to the workbench. Subsequently, the leftmost notch moves back to the end of the conveying channel and engages with another outer ring of the bearing for the same movement. The previous outer ring of the bearing is matched by the second notch on the left and moves one unit to the right. In summary, the step-by-step movement of the outer ring of the bearing is realized. When the outer ring of the bearing moves below the glue injection machine, glue injection into the inner part of the outer ring of the bearing is realized. When the outer ring of the bearing moves below the roller installation machine, the rollers are installed into the outer ring of the bearing. In summary, the installation of the rollers in the screw bearing is realized.

[0011] In this solution, three notches are provided on the side of the push plate. This setting can reduce the displacement of the push plate along the length direction of the workbench and prevent the roller installation machine and the glue injection machine from being installed too close.

[0012] In this solution, the movement of the push plate is preferably a right-angled triangle movement with a clockwise movement trajectory.

[0013] To illustrate the specific structure of the driving mechanism, the present utility model adopts that the driving mechanism includes: a slide rail, which is fixedly arranged on one side of the workbench, and its length direction is parallel to the length direction of the workbench; a sliding mounting seat, which is slidably arranged on the slide rail; a first air cylinder perpendicular to the length direction of the workbench, which is fixed on the sliding mounting seat, and the push plate is fixed at its output end; two second air cylinders arranged oppositely and parallel to the length direction of the workbench, which are fixed on both sides of the slide rail through a mounting frame.

[0014] The movement of the push plate perpendicular to the length of the workbench is realized by the first air cylinder, and the reciprocating movement of the push plate along the length direction of the workbench is realized by the cooperation of the piston rods of the two second air cylinders extending or retracting. In this way, the two-axis movement of the push plate is realized.

[0015] To realize the accuracy of the movement of the push plate, the present utility model adopts that a guiding hole is provided on the sliding mounting seat; a guiding rod is provided on the push plate and is matched with the guiding hole.

[0016] The guiding rod is slidably arranged in the guiding hole. In this way, the push plate can only move along the axis direction of the guiding rod, that is, the movement of the push plate perpendicular to the length of the workbench is realized.

[0017] To prevent the outer ring of the bearing from falling outside the workbench during the step movement, the present utility model adopts that a abutting section is convexly arranged on the outer side of the length side of the workbench; when the outer ring of the bearing moves to the workbench, the outer ring of the bearing is always in contact with the abutting section.

[0018] The abutting section restricts the outer ring of the bearing from falling outside the workbench and plays a limiting role on the outer ring of the bearing.

[0019] In order to limit the outer ring of the bearing on the conveying channel, the present utility model adopts that a guiding plate is arranged on the conveying channel; an L-shaped and communicating horizontal guiding channel and a vertical guiding channel are formed between the guiding plates;

[0020] When the outer ring of the bearing moves to the connection of the horizontal guiding channel and the vertical guiding channel, at this time, the outer ring of the bearing can cooperate with the notch of the push plate, and the outer ring of the bearing is horizontally introduced onto the workbench along the horizontal guiding channel.

[0021] In order to realize the rotation of the outer ring of the bearing when installing the roller, the present utility model adopts that a rotating disk driven by a motor is arranged on the workbench and below the roller installing machine; the surface of the rotating disk is flush with the surface of the workbench;

[0022] When the outer ring of the bearing moves to the rotating disk, at this time, the outer ring of the bearing cooperates with the notch and does not move, and the bearing only fully cooperates with the rotating disk to realize self-rotation, which is convenient for the installation of the roller.

[0023] The beneficial effects of the present utility model: The present utility model is a roller installation tooling for a stepping screw bearing. The conveying channel and the working strip are vertically arranged. First, the outer ring of the bearing is placed on the conveying channel. When the outer ring of the bearing moves to the end of the conveying channel, the push plate is driven to move by a driving mechanism, and the notch on the leftmost side cooperates with the outer ring of the bearing, and the outer ring of the bearing is transported from the conveying channel to the workbench. Subsequently, the notch on the leftmost side moves to the end of the conveying channel again and cooperates with another outer ring of the bearing to perform the same movement. The previous outer ring of the bearing is matched by the second notch on the left and moves one unit to the right. In summary, the stepping movement of the outer ring of the bearing is realized. When the outer ring of the bearing moves below the glue injection machine, glue injection into the interior of the outer ring of the bearing is realized. When the outer ring of the bearing moves below the roller installing machine, the roller is installed in the outer ring of the bearing; In summary, the installation of the roller in the screw bearing is realized.

Detailed implementation mode

[0030] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0031] As Figure 1-2 Shown in FIGS. 10 and 4, the present utility model is a roller installation tooling for a step - type screw bearing, comprising: a conveying channel 1; a workbench 2, which is arranged on one side of the conveying channel 1 and is flush with the conveying channel 1; a glue injection machine 3, which is arranged outside the length side of the workbench 2; a roller installation machine 4, which is arranged outside the length side of the workbench 2 and is located on one side of the glue injection machine 3; a push plate 5, which is arranged on the workbench 2 and the conveying channel 1, at least two notches 6 are arranged on its length side, and its bottom height is higher than that of the conveying channel 1; a driving mechanism, which drives the push plate 5 to make a two - axis reciprocating motion, and with the cooperation of the notches 6, guides the outer ring of the bearing 7 from the conveying channel 1 to the workbench 2, and realizes the step - by - step linear motion of the outer ring of the bearing 7 along the length direction of the workbench 2 on the workbench 2, and passes under the glue injection machine 3 and the roller installation machine 4;

[0032] In this solution, the conveying channel and the workbench are vertically arranged. First, the outer ring of the bearing is placed on the conveying channel. When the outer ring of the bearing moves to the end of the conveying channel, the driving mechanism drives the push plate to move, and the left - most notch is matched with the outer ring of the bearing, transporting the outer ring of the bearing from the conveying channel to the workbench. Subsequently, the left - most notch moves back to the end of the conveying channel through the driving mechanism and cooperates with another outer ring of the bearing for the same movement. The previous outer ring of the bearing is matched by the second notch on the left and moves one unit to the right. In summary, the step - by - step movement of the outer ring of the bearing is realized. When the outer ring of the bearing moves under the glue injection machine, glue injection into the inner part of the outer ring of the bearing is realized. When the outer ring of the bearing moves under the roller installation machine, the roller is installed into the outer ring of the bearing. In summary, the installation of the roller in the screw bearing is realized.

[0033] In this solution, three notches are arranged on the side of the push plate. Such a setting can reduce the displacement of the push plate along the length direction of the workbench and prevent the roller installation machine and the glue injection machine from being installed too close.

[0034] In this solution, the movement of the push plate is preferably a right - angled triangle movement with a clockwise movement trajectory.

[0035] As shown Figure 1-2 in the figure, to illustrate the specific structure of the driving mechanism, the driving mechanism of the present utility model includes: a slide rail 8, which is fixedly arranged on one side of the workbench 2, and its length direction is parallel to the length direction of the workbench 2; a sliding mounting seat 9, which is slidably arranged on the slide rail 8; a first air cylinder 10 perpendicular to the length direction of the workbench, which is fixed on the sliding mounting seat 9, and a push plate 5 is fixed at its output end; two second air cylinders 11 arranged opposite to each other and parallel to the length direction of the workbench, which are fixed on both sides of the slide rail 8 through a mounting frame;

[0036] The push plate is moved perpendicular to the length of the workbench by the first air cylinder, and the reciprocating movement of the push plate along the length direction of the workbench is realized by the cooperation of the piston rods of the two second air cylinders extending or retracting, thus realizing the two-axis movement of the push plate;

[0037] Since the piston rods of one first air cylinder and two second air cylinders have only two states of extending or retracting, the response speed of the first air cylinder and the second air cylinders driving the push plate to move is relatively fast, improving the transfer efficiency of the bearing outer ring.

[0038] As shown Figure 1 in the figure, to achieve the accuracy of the movement of the push plate, the present utility model adopts that a guiding hole is arranged on the sliding mounting seat 9; a guiding rod 13 is arranged on the push plate 5 and is matched with the guiding hole 12;

[0039] The guiding rod is slidably arranged in the guiding hole, so that the push plate can only move along the axis direction of the guiding rod, that is, the movement of the push plate perpendicular to the length of the workbench is realized.

[0040] As shown Figure 1-2 in the figure, to prevent the bearing outer ring from falling outside the workbench during the stepping movement, the present utility model adopts that a abutting section 12 is convexly arranged on the outer side of the length side of the workbench 2; when the bearing outer ring 7 moves onto the workbench 2, the bearing outer ring 7 is always in contact with the abutting section 12;

[0041] The abutting section restricts the bearing outer ring from falling outside the workbench and plays a role in limiting the bearing outer ring.

[0042] As shown Figure 4 in the figure, to limit the bearing outer ring on the conveying channel, the present utility model adopts that a guiding plate 14 is arranged on the conveying channel 1; an L-shaped and communicating transverse guiding channel 142 and a vertical guiding channel 141 are formed between the guiding plates 14;

[0043] When the bearing outer ring moves to the connection of the transverse guiding channel and the vertical guiding channel, at this time, the bearing outer ring can be matched with the notch of the push plate, and the bearing outer ring is horizontally introduced onto the workbench along the transverse guiding channel;

[0044] The lateral guiding channel is arranged flush with the side of the abutting section, ensuring that the outer ring of the bearing can be smoothly introduced from the lateral channel to the abutting section.

[0045] As Figure 3 shown, in order to realize the rotation of the outer ring of the bearing when installing the roller, the present utility model adopts a rotating disk 15 driven by a motor and arranged below the roller installing machine 4 and on the workbench 2; the surface of the rotating disk 15 is flush with the surface of the workbench 2;

[0046] When the outer ring of the bearing moves to the rotating disk, at this time, the outer ring of the bearing cooperates with the notch and does not move, and the bearing only cooperates with the rotating disk to realize self-rotation, which is convenient for the installation of the roller.
