Description

Technical Field

[0001] This utility model relates to the field of fuel injector processing technology, specifically a conveying device for processing engine fuel injectors. Background Technology

[0002] The machining and design of engine injectors involves high-precision micro-orifice manufacturing. Since the precision of the injector nozzle directly affects the atomization efficiency of subsequent fuel injection, laser drilling technology is required to process the injector nozzle into micro-orifices.

[0003] Currently, injectors using laser drilling have certain defects in actual use. After the injector blank is made, it needs to be transferred by a conveying device until it enters the next stage. However, after the existing conveying device transfers the injector to the drilling stage, it is difficult to accurately adjust the micro-hole spacing between the injector end to be processed and the laser drill. Once there is a deviation in the micro-hole spacing, it will affect the atomization efficiency of the injector.

[0004] In view of this, a conveying device for processing engine injectors was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] A conveying device for processing engine injectors includes a feeding mechanism, multiple injector blanks clamped within the feeding mechanism, a calibration and positioning mechanism mounted on the feeding mechanism, and a nozzle punching mechanism mounted on the calibration and positioning mechanism. The feeding mechanism includes two housings, within which multiple rollers are movably mounted. A conveyor belt is externally connected to the multiple rollers, and multiple clamps are fixedly mounted on the outside of the conveyor belt. The calibration and positioning mechanism includes a base plate mounted on one of the housings, with a sleeve fixedly mounted on the base plate. A hydraulic component is fixedly mounted inside the sleeve, and a support plate is mounted on the hydraulic component. The nozzle punching mechanism includes a laser drill movably mounted within the support plate. Two cover plates are mounted on the outside of the laser drill, and positioning rods are installed within the two cover plates. A nozzle calibration plate is movably mounted at the bottom end of the positioning rod, and a protective pad is fixedly mounted on the outside of the nozzle calibration plate.

[0008] In a preferred embodiment, the present invention can be further configured such that: a clamp is movably mounted on the outside of the sleeve, a pull cable is fixedly mounted on the outer end of the clamp, and a horizontally placed first spring is fixedly connected between the inner wall of the clamp and the sleeve.

[0009] In a preferred embodiment, the present invention can be further configured such that: an outer frame is fixedly installed on the hydraulic sub-rod within the hydraulic component, the bottom end of the outer frame has a groove, and a shaft is inserted into the groove, and the cable is connected to the shaft.

[0010] In a preferred embodiment, the present invention can be further configured such that: a second spring is fixedly installed at the top of the outer frame, and a hydraulic sub-rod in the hydraulic component is adapted to pass through the second spring; the top of the second spring is fixedly connected to the support plate, and a first gear is fixedly installed on the support plate.

[0011] In a preferred embodiment, the present invention can be further configured such that two combined bolts are installed inside the cover plate.

[0012] In a preferred embodiment, the present invention can be further configured such that: a housing is fixedly installed on the plate end at the top of the positioning rod, a motor is fixedly installed inside the housing, and a second gear is fixedly installed on the transmission shaft inside the motor.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] 1. This utility model clamps multiple injectors to be processed at equal intervals on an existing conveying device until the ends of the clamped injectors are aligned. As the hydraulic components operate, the positioning rod and the nozzle calibration plate quickly press against the top of the injector. When the motor runs and rotates around the first gear with the help of the second gear, the positioning rod will drive the cover plate and the laser drill to rotate around the nozzle calibration plate. During the rotation, the laser drill can work with the nozzle calibration plate to perform precise drilling on the injector, avoiding accidental damage to the top of the injector by the laser beam.

[0017] 2. This utility model provides coaxial marking support for the laser drill by using the positioning rod and the nozzle calibration disk axis. As the laser drill rotates regularly, the laser beam can achieve precise drilling without interruption, avoiding the problem of non-straight micro-holes inside the injector.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a conveying device for processing engine injectors.

[0031] Example 1:

[0032] Combination Figures 1 to 5As shown, the present invention provides a conveying device for processing engine injectors, including a feeding mechanism 100, a plurality of injector blanks 200 clamped in the feeding mechanism 100, a calibration and positioning mechanism 300 mounted on the feeding mechanism 100, and a nozzle punching mechanism 400 mounted on the calibration and positioning mechanism 300. The calibration and positioning mechanism 300 is used to precisely fix the injector blanks 200 and to provide a support carrier for the nozzle punching mechanism 400 to punch holes. The nozzle punching mechanism 400 is used to precisely punch holes in the fixed injector blanks 200.

[0033] The feeding mechanism 100 includes two housings 110, and multiple rollers 120 are movably installed inside the two housings 110. The multiple rollers 120 are externally connected to a conveyor belt 130, and multiple clamps 140 are fixedly installed on the outside of the conveyor belt 130.

[0034] The calibration and positioning mechanism 300 includes a base plate 310 mounted on one of the housings 110, a sleeve 3101 fixedly mounted on the base plate 310, a hydraulic component 340 fixedly mounted inside the sleeve 3101, a support plate 350 mounted on the hydraulic component 340, a clamp 320 movably mounted outside the sleeve 3101, a cable 3201 fixedly mounted on the outer end of the clamp 320, a horizontally placed first spring 330 fixedly connected between the inner wall of the clamp 320 and the sleeve 3101, an outer frame 370 fixedly mounted on the hydraulic sub-rod inside the hydraulic component 340, a groove is provided at the bottom end of the outer frame 370, and a shaft is inserted into the groove, and the cable 3201 is connected to the shaft;

[0035] The punching mechanism 400 includes a laser puncher 450 movably installed in a support plate 350. Two cover plates 410 are installed on the outside of the laser puncher 450. A positioning rod 420 is installed inside the two cover plates 410. A punching calibration plate 4201 is movably installed at the bottom of the positioning rod 420. A protective pad 4202 is fixedly installed on the outside of the punching calibration plate 4201.

[0036] The nozzle calibration plate 4201 has multiple fan-shaped grooves inside, and a vertical hole is provided in the middle of the fan-shaped groove.

[0037] Preferably, the clamp 140 is composed of a conical pad and two elastic clamping pieces, and the outer ends of the two elastic clamping pieces are provided with guide bevels;

[0038] The clamp 320 has a semi-circular limiting groove in the middle of its inner side. As the hydraulic component 340 runs, its internal hydraulic rod rises, and the outer frame 370 fixed on the hydraulic rod pulls the cable 3201. The cable 3201 stretches the clamp 320 to move outward laterally. When the external transmission device drives the conveyor belt 130 and multiple clamps 140 to rotate at a constant speed, the multiple evenly distributed injector blanks 200 will be precisely fixed and clamped in conjunction with the regularly extended clamp 320, which facilitates the subsequent pressing of the nozzle calibration plate 4201.

[0039] In addition, after the hydraulic rod descends, it drives the support plate 350 and the laser drill 450 to descend synchronously. The laser drill 450, which is installed in the support plate 350 by bearings, rotates around the nozzle calibration plate 4201 as the axis. The laser beam passes through multiple vertical holes inside the nozzle calibration plate 4201 to precisely drill the top of the injector blank 200.

[0040] Example 2:

[0041] Combination Figures 3 to 5 As shown, in the above embodiment, a second spring 360 is fixedly installed at the top of the outer frame 370, and the hydraulic sub-rod in the hydraulic component 340 is adapted to pass through the second spring 360. The top of the second spring 360 is fixedly connected to the support plate 350, and a first gear 3501 is fixedly installed on the support plate 350.

[0042] Two combination bolts 4101 are installed inside the cover plate 410. A T-shaped groove is provided on the inner side of the cover plate 410, and a load-bearing frame 430 is movably installed in the T-shaped groove. A housing 440 is fixedly installed on the plate end at the top of the positioning rod 420. A motor 4401 is fixedly installed inside the housing 440, and a second gear 4402 is fixedly installed on the drive shaft inside the motor 4401.

[0043] Preferably, the second gear 4402 is adapted to mesh with the first gear 3501. The start and stop of the motor 4401 are controlled by the cloud. As the motor 4401 runs and drives the second gear 4402 to rotate, the cover plate 410, the positioning rod 420 and the laser drill 450 will rotate at a constant speed around the bearing inside the support plate 350. The top of the laser drill 450 and the nozzle calibration plate 4201 are respectively positioned and constrained. Therefore, the circumferential rotation of the laser drill 450 and the positioning rod 420 can be kept stable, avoiding abnormal vibration of the laser beam emitted by the laser drill 450 during the drilling of the top of the injector blank 200.

[0044] The working principle and usage process of this utility model are as follows: Multiple injector blanks 200 to be processed are pre-assembled into multiple corresponding clamps 140 until the tops of the multiple evenly distributed injector blanks 200 are level.

[0045] In operation, the hydraulic component 340 is operated via the cloud. As the hydraulic rod inside the hydraulic component 340 rises, the outer frame 370, fixedly mounted on the hydraulic rod, pulls the cable 3201 and the clamp 320 to extend relative to each other. Under the lateral elastic pressure of the first spring 330, the clamp 320 maintains a non-interference gap with multiple injector blanks 200. Then, the external transmission device drives the conveyor belt 130, and the multiple clamps 140 fixed outside the conveyor belt 130 drive the multiple injector blanks 200. As the hydraulic rod retracts, the clamp 320 quickly clamps and positions one of the injector blanks 200 under the lateral pressure of the first spring 330. As the second spring 360 presses down, the support plate 350 drives the nozzle punching mechanism 400 to descend as a whole. The nozzle calibration plate 4201 and the protective pad 4202 are precisely inserted into the concave hole at the top of the injector blank 200. A hole inside the nozzle calibration plate 4201 is symmetrical to the laser beam emitted by the laser drill 450.

[0046] When the motor 4401 starts and rotates around the circumference of the second gear 4402, the laser drill 450, which is installed in the laser drill 450 through the bearing, will rotate around the nozzle calibration plate 4201 as the center, and the remaining holes inside the nozzle calibration plate 4201 can be used to quickly drill holes in the injector blank 200 with the laser beam emitted by the laser drill 450.

[0047] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
