Abstract
Description
Technical Field
[0001] This utility model relates to the field of sleeve selector technology, and specifically to a simple sleeve selector. Background Technology
[0002] Tightening guns are widely used and critical tools in the assembly of industrial parts, particularly in the assembly of automobiles, aircraft, and intelligent robots. When tightening different bolts, a standard socket selector is required to match the appropriate tightening program and ensure the bolt torque is within acceptable limits.
[0003] Currently, the most widely used and relatively expensive sleeve selector is the Atlas sleeve selector. The sleeve selector works as follows: It has four positions (A, B, C, and D) for holding four different sleeves. The sleeve selector communicates with the tightening gun via a network. When a single sleeve is manually picked up, the sleeve selector sends a corresponding command to the tightening gun, and the controller switches to the appropriate tightening program to ensure correct tightening.
[0004] Most sleeve selectors on the market use Atlas Copco's proprietary sleeve selectors. Atlas Copco's proprietary sleeve selectors are characterized by high procurement costs, long delivery cycles, and complex debugging, which can negatively impact the commissioning of assembly lines. Utility Model Content
[0005] This utility model provides a simple sleeve selector that reduces costs and improves expandability.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A simple sleeve selector includes a selector body and two proximity sensors. The selector body has two sensor mounting ears on both sides and two sleeve placement holes. Sleeves are placed in the sleeve placement holes, and the upper end of the sleeve placement hole is located inside the sensor mounting ears. One side of each proximity sensor is installed in the sensor mounting ear. The proximity sensors are electrically connected to a PLC, and the PLC is connected to the controller of the tightening gun.
[0008] Preferably, the sleeve placement hole is a through hole, and the two sleeve placement holes have different diameters.
[0009] Preferably, the selector body has a cuboid structure and two mounting holes.
[0010] Preferably, the axis of the mounting hole of the body is perpendicular to the axis of the sleeve placement hole.
[0011] Preferably, the mounting hole on the body is a stepped hole.
[0012] Preferably, the sensor mounting ear is provided with a sensor mounting hole.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention greatly simplifies the structure of traditional sleeve selectors, making them smaller in size and more expandable. It can hold two different types of sleeves at once, reducing costs by 95%. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] As shown in the figure, this utility model discloses a simple sleeve selector, including a selector body 1 and two proximity sensors 2. The selector body 1 has two sensor mounting ears 11 on both sides and two sleeve placement holes 12. Sleeves 3 are placed in the sleeve placement holes 12, with the upper end of each hole located inside the sensor mounting ears 11. One side of each proximity sensor 2 is mounted on the sensor mounting ear 11. The proximity sensors 2 are electrically connected to a PLC 4, which is connected to the controller of a tightening gun 5. The PLC and the tightening gun controller can be connected in various ways, such as direct electrical connection or wireless communication.
[0022] Compared with traditional sleeve selectors, this utility model has a greatly simplified structure and can reduce costs by more than 95%. At the same time, due to the simplified structure, maintenance costs are also significantly reduced.
[0023] The simplified structure of this utility model greatly reduces the failure rate and maintenance costs.
[0024] In one embodiment of this utility model, the sleeve placement hole 12 is a through hole, and the two sleeve placement holes 12 have different diameters. By setting the diameter of the sleeve placement hole 12, the corresponding sleeve is selected for placement.
[0025] In one embodiment of this utility model, the selector body 1 has a cuboid structure and is provided with two mounting holes 13. The selector body 1 has a square structure, low processing cost, and is easy to install.
[0026] In one embodiment of this utility model, the axis of the mounting hole 13 of the body is perpendicular to the axis of the sleeve placement hole 12.
[0027] In one embodiment of this utility model, the mounting hole 13 is a stepped hole. The stepped hole 13 facilitates the installation of the selector body. Of course, the mounting hole 13 can also be set as a blind hole.
[0028] In one embodiment of this utility model, a sensor mounting hole 111 is provided at the sensor mounting ear 11. The sensor mounting hole 111 is used to mount a proximity sensor.
[0029] The working process of this utility model is as follows:
[0030] The sleeve is manually removed from this utility model and installed on the tightening linkage of the tightening gun. The I / O signal of the proximity sensor corresponding to this utility model is input to the PLC. After program comparison, the PLC outputs the corresponding instruction to the controller of the tightening gun. The controller of the tightening gun starts the tightening program corresponding to the current sleeve and completes the program call.
[0031] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
