Description

Technical Field

[0001] This utility model relates to the field of aerospace parts processing technology, and in particular to an aerospace parts marking device. Background Technology

[0002] Pipe fittings in aerospace fasteners are diverse and produced in small batches. Each product requires a permanent marking in a designated area before leaving the factory to trace material batches, specifications, and production information. Current technology generally employs benchtop pneumatic or laser marking machines with manual loading and positioning. Operators must place the pipe fittings one by one into the fixture, start marking, and then manually unload them. This process is labor-intensive and slow; furthermore, manual positioning errors can easily lead to skewed or inconsistent marking depths, affecting subsequent assembly and inspection. With increasing aerospace production and the growing demands for lean manufacturing, traditional methods can no longer meet the requirements of high-efficiency, high-consistency online production. There is an urgent need for a fully automated aerospace parts marking machine capable of automatically loading, positioning, marking, and unloading pipe fittings. Utility Model Content

[0003] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a marking device for aerospace parts.

[0004] The technical solution is as follows: A marking device for aerospace parts includes a processing table, a conveyor, and a vibrating feeder. The processing table is equipped with a laser marking machine, a front baffle, a rear baffle, and side baffles. A material ejection channel is defined between the front and rear baffles, and a material infeed channel is defined between the side and rear baffles. The material ejection channel is perpendicular to and intersects the material infeed channel to form an L-shaped channel. The marking head of the laser marking machine is located directly above the corner of the L-shaped channel. The conveyor includes a conveyor belt and baffle structures on both sides of the conveyor belt. The infeed end of the conveyor is connected to the outlet of the vibrating feeder, and the outlet end is connected to the material infeed channel. A notch is provided at the bottom of the side baffle to connect the material ejection channel and the material infeed channel. A transfer cylinder is provided on one side of the notch to push parts from the material infeed channel to the material ejection channel. A material detection sensor is provided above the notch to detect whether there are parts being processed at the marking position.

[0005] Furthermore, the conveyor's baffle structure includes a low baffle and a high baffle disposed on both sides of the conveyor belt. The high baffle is provided with a top baffle that is narrower than the conveyor belt and has an adjustable height. The top baffle is mounted on the high baffle via an ear plate structure.

[0006] Furthermore, the top of the side baffle is provided with a long groove extending along its length; an adjusting nut that can slide along the long groove is provided in the long groove; an adjusting bolt is connected to the material detection sensor, and the adjusting bolt is screwed into the adjusting nut.

[0007] Furthermore, the upper surface of the processing table is provided with a plurality of mounting threaded holes arranged equidistantly along a straight line; the front baffle, rear baffle and side baffle are respectively detachably fixed in the mounting threaded holes by fastening bolts.

[0008] Furthermore, the top baffle is parallel to the surface of the conveyor belt, and the top of the top baffle is provided with an ear plate with a round hole, and the top of the high baffle is provided with an ear plate with a straight hole. The ear plate with the round hole and the ear plate with the straight hole are connected by bolts.

[0009] Furthermore, the discharge end of the unloading channel is provided with an inclined guide plate; a collection bin is provided below the end of the guide plate.

[0010] The beneficial effects are:

[0011] 1. This utility model uses a vibrating feeding tray and a conveyor to continuously feed materials. The L-shaped channel integrates feeding, marking, and unloading on the same platform. The transfer cylinder can complete the positioning by pushing the material at the notch in one go. The laser head marks the part immediately above the corner. The detection sensor confirms the part is in place in real time to avoid missing the mark. The whole process does not require manual intervention, the marking speed is greatly improved, and the error of the marking position is reduced.

[0012] 2. This utility model forms an adjustable height limiting channel by setting high and low baffles and an adjustable top baffle on both sides of the conveyor belt, which prevents pipe joints from stacking or being placed horizontally, and ensures stable feeding of a single row.

[0013] 3. This utility model uses a long groove and a sliding nut to allow the sensor to move quickly along the side baffle and lock, enabling rapid fine-tuning of the marking position and reducing downtime for model changes.

[0014] 4. This utility model uses equally spaced threaded holes on the processing table, and all baffles can be bolted at any position. It is modularly assembled, compatible with various pipe fittings and fixtures, and has strong expandability.

Detailed Implementation

[0021] 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.

[0022] like Figure 1-4 The aerospace parts marking device shown is particularly suitable for fully automatic marking of aerospace pipe fittings (such as models AN929-2, AN929-3, AN929-4, etc.). The device includes a processing table 1, a conveyor 2, and a vibrating feeder 3. The upper surface of the processing table 1 has multiple sets of mounting threaded holes 11 arranged equidistantly along a straight line. The front baffle 5, the rear baffle 6, and the side baffle 7 are detachably fixed in the mounting threaded holes 11 by fastening bolts, forming a modular assembly structure that is compatible with different specifications of pipe fitting fixtures.

[0023] refer to Figure 2 The vibrating feeding plate 3 outputs the pipe fittings in an orderly manner to the feed end of the conveyor 2. The conveyor belt 21 of the conveyor 2 is equipped with baffle structures on both sides, including a low baffle 22, a high baffle 23, and a top baffle 24. The top baffle 24 is bolted to the high baffle 23 via a lug 25 with a round hole and a lug 26 with a slotted hole. The height of the top baffle 24 can be changed by adjusting the tightness of the bolts. Figure 2 This forms an adjustable limiting channel to avoid pipe joints from stacking or being placed horizontally, ensuring that a single line is stably fed into the feeding channel 76.

[0024] The feeding channel 76 is defined by the side baffle 7 and the rear baffle 6, and the unloading channel 56 is defined by the front baffle 5 and the rear baffle 6. The two intersect perpendicularly to form an L-shaped channel. Figure 1 , Figure 4 ).

[0025] refer to Figure 3A notch 71 is opened at the bottom of the side baffle 7 to connect the feeding channel 76 and the unloading channel 56. A transfer cylinder 8 is provided on one side of the notch 71, and a push plate 81 is installed at the front end of its telescopic rod. When the pipe joint is sent into the feeding channel 76 by the conveyor 2 and moves to the position of the notch 71: the material detection sensor 9 detects the pipe joint's arrival signal in real time, and the marking head of the laser marking machine 4 is located directly above the corner, immediately printing a permanent mark on the surface of the pipe joint. Then, the transfer cylinder 8 pushes the pipe joint laterally to the unloading channel 56 through the push plate 81, and finally it is collected.

[0026] It should be noted that the position of the material detection sensor 9 can be quickly and finely adjusted. A long groove 72 is opened on the top of the side baffle 7, and a sliding adjustment nut is installed in the groove. The sensor is screwed into the nut by adjusting the bolt 91, and then locked after moving along the long groove 72. This adapts to different pipe joint sizes and reduces downtime for changing models.

[0027] In addition, the discharge end of the unloading channel 56 is equipped with an inclined guide plate 10. The pipe joints marked after being placed in the collection bin 101 are slid into the collection bin 101 through the guide plate 10 to avoid scattering and accumulation.

[0028] refer to Figure 1 or Figure 4 The controller 4 is fixed on the processing table 1 and is electrically connected to the laser marking machine 4, material detection sensor 9, material transfer cylinder 8, conveyor 2, etc. It is used to receive sensor signals and control and coordinate the action sequence of each component to realize full closed-loop automatic control.

[0029] Compared with other devices on the market, the advantages of this utility model are that it integrates vibration feeding, conveying and positioning, cylinder material transfer, laser marking and material collection functions, solving the problems of low efficiency and large errors in manual operation; in addition, the height of the baffle, the position of the sensor, and the spacing between the inlet and outlet channels are adjustable, and it is compatible with various pipe fittings such as the AN929 series; the L-shaped channel and notch 71 design of this device ensures positioning accuracy, the sensor 9 can prevent missed marking, and the modular structure of the processing table 1, the front baffle 5, the rear baffle 6 and the side baffle 7 supports quick disassembly, replacement and adjustment, meeting the needs of small-batch multi-variety production in aviation.
