Description

TECHNICAL FIELD

[0001] The utility model relates to automatic production processing feeding field, concretely relates to a double position sleeve laser processing feeding equipment. BACKGROUND

[0002] The sleeve refers to the abbreviation of the sleeve wrench, because it is sleeved on various wrenches and is like a cylinder, so it is commonly known as a sleeve, which is a commonly used production, maintenance and living tool. The sleeve is suitable for screwing bolts or nuts in very narrow or deep recessed positions, and can be divided into cold extrusion sleeves, tapered thread sleeves and straight thread sleeves, which are composed of multiple sleeves with hexagonal holes or twelve corner holes and various accessories such as handles and connecting rods. Before completing the boxing, the sleeve needs to print information on the sleeve surface, and the traditional pressure printing process is used. With the development of laser etching technology, laser marking gradually replaces pressure marking. Because the positioning point of the laser equipment is usually determined when inputting the control, the surface of the sleeve is usually arc-shaped, and if there is a deviation, it may cause the position deviation of the etched information, resulting in that the content of the etching cannot be recognized finally, so people usually place the feeding sleeve to ensure the correctness of etching.

[0043] The core problem of material feeding and processing is solved by automating the feeding of sleeves onto a positioning conveyor belt from the upper-level production equipment.

[0044] The sleeve positioning conveyor belt includes a chain conveyor belt, and a sleeve positioning seat 2 is fixed on the support shaft of the chain conveyor belt, with one sleeve positioning seat fixed for every two support shafts;

[0045] Chain conveyor belts are driven by stepper motors.

[0046] The chain conveyor in this embodiment is modified from the same conveyor, so the two workstations can be mirror-imaged, and due to the arrangement of the infrared trigger switches, the two conveyors do not interfere with each other when rotating synchronously. The chain conveyor can also be modified to be used alone.

[0047] The chain conveyor is provided with two groups of infrared trigger switches, wherein the first group and the second group are spaced apart by three sleeve positioning seats;

[0048] An auxiliary positioning wheel 6 is arranged in front of the second group of infrared trigger switches;

[0049] The auxiliary positioning wheel is two horizontally placed pulleys arranged as mirror images of the vertical plane of the conveying axis of the sleeve positioning conveyor;

[0050] The auxiliary positioning wheel cooperates with the sleeve positioning seat to ensure the horizontal position of the sleeve positioning seat.

[0051] The first group of infrared trigger switches 8 is used to determine the remaining number on the workstation and the starting time required by the laser, so that the laser is paused for heat dissipation when there is no material on the chain conveyor.

[0052] The second group of infrared trigger switches 7 is a position trigger, and when the sleeve positioning seat containing the sleeve passes, the sleeve on it triggers the infrared trigger switch, so that the conveyor is paused and the sleeve transfer device is triggered synchronously.

[0053] The number of sleeve positioning seats is greater than or equal to 20, and 50 are used in this embodiment to ensure sufficient automatic processing margin.

[0054] The sleeve positioning seat comprises a base, a middle section and a sleeve joint, which are integrally formed; the base is transversely provided with at least two through holes. The middle section is a cylinder for cooperating with the auxiliary positioning wheel.

[0055] The sleeve positioning conveyor, the sleeve transfer device, the sleeve positioning seat, the unloading track and the laser device form a single-sided machining equipment;

[0056] Two single-sided machining equipments are mirror-imaged to form a double-station sleeve laser machining feeding equipment;

[0057] The mirror plane is parallel to the vertical plane of the conveying axis of the sleeve positioning conveyor;

[0058] The distance between the center line of the sleeve positioning conveyor and the center point of the sleeve positioning seat is equal to the distance between the center point of the sleeve positioning seat and the center line of the unloading track.

[0059] The sleeve transfer device comprises a horizontal displacement air cylinder, a horizontal sliding rail device, a vertical sliding rail device 9, a vertical displacement air cylinder 10, a clamping jaw air cylinder base plate 11, and two parallel clamping jaw air cylinders 12;

[0060] The rail of the horizontal sliding rail device is arranged on the ground or a fixed support; a sliding block is connected with the base plate of the vertical sliding rail device; and the telescopic end of the horizontal displacement air cylinder is connected with the sliding block;

[0063] A gripping block is arranged on the clamping jaw of the clamping jaw air cylinder, and the working end of the gripping block is in the form of an inner arc; and a semicircular groove is arranged on the arc surface at equal intervals. Embodiment

[0064] The embodiment is basically the same as Embodiment 1, and the difference lies in the arrangement of the workstations. Since the device is designed as a double workstation, the problem of using several sleeve positioning conveying belts is involved. In Embodiment 1, two sleeve positioning conveying belts are used, while in this embodiment, only one is used.

[0065] The sleeve transfer device, the sleeve positioning seat, the unloading track, and the laser device form a single-sided machining equipment.

[0066] The two single-sided machining equipments share one sleeve positioning conveying belt; and the mirror surface is parallel to the vertical plane of the conveying axis of the sleeve positioning conveying belt.

[0067] Taking the vertical plane of the conveying direction as a reference plane, on the same horizontal line perpendicular to the reference plane, there is only one sleeve transfer device on the left or right, otherwise the sleeve transfer device on the same horizontal line cannot obtain a workpiece. Therefore, the single-sided machining equipment is in a staggered mirror image relationship.

[0068] As for the infrared trigger switch, it is sufficient to only reserve two groups of infrared switches. If it is necessary to stagger the feeding, it is also feasible. If it is necessary to customize or mix materials, an additional third group of infrared trigger switches needs to be arranged. However, for the design of providing the same material on the same conveying belt, the same design of two groups of infrared trigger switches as in Embodiment 1 can be reserved.

[0069] The foregoing description of the disclosed embodiments enables a person skilled in the art to make or use the application. Modifications of these embodiments will occur to persons of skill in the art, and that the appended claims are intended to cover all such modifications that do not depart from the true spirit and scope of the application. Therefore, the application is not limited to the embodiments shown but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
