Abstract
Description
Technical Field
[0001] This utility model belongs to the field of gear marking printing technology, specifically a half-shaft gear marking printing device. Background Technology
[0002] Half-shaft gears are typically used as a component in automotive differentials. They are bevel gears and are usually used in pairs. Half-shaft gear marking printers are industrial devices used to mark and print on the surface of half-shaft gears. Their core function is to accurately engrave characters, patterns, QR codes, and other information onto the gear surface using marking technologies such as laser, inkjet, dot matrix, or pneumatic marking to meet the needs of production traceability, quality control, and anti-counterfeiting.
[0003] Current half-shaft gear marking and printing devices still have shortcomings in practical use. The most obvious one is that during the marking and printing process, the half-shaft gear is usually fixed by clamping and limiting to prevent the gear from shifting. However, such fixing makes it difficult to flexibly rotate and adjust the half-shaft gear according to the diverse printing needs, thus reducing the marking and printing efficiency of the half-shaft gear. To address this, we propose a half-shaft gear marking and printing device. Utility Model Content
[0004] The purpose of this invention is to provide a half-shaft gear marking printing device to solve the problems mentioned in the background art.
[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0006] Specifically, this application describes a half-shaft gear marking printing device, comprising: a worktable and fixed plates fixedly connected to the two side walls of the worktable; support plates fixedly connected to the top two ends of the worktable; inclined sliding grooves provided at both ends of the side walls of the support plates; a printing element for marking the half-shaft gear provided at one top end of the support plate; and an adjusting element for positioning the half-shaft gear provided at the other top end of the support plate.
[0007] The inner cavity of the chute is slidably connected to a movable rod, one end of which is rotatably connected to a limit wheel, and the top of the movable rod is fixedly connected to a first motor that drives the limit wheel to rotate.
[0008] A movable plate is slidably mounted on the fixed plate. Through grooves are provided at both ends of the side wall of the movable plate. A sliding rod is fixedly connected to the inner cavity of the through groove. A slider is slidably connected to the side wall of the sliding rod. The slider is fixedly connected to the movable rod. A driving component for moving the movable plate is provided on the fixed plate.
[0009] As a preferred technical solution of this application, the printing component includes a U-shaped frame, which is fixedly connected to one top end of a support plate. A telescopic cylinder is fixedly connected to the top of the U-shaped frame, and the power output end of the telescopic cylinder passes through the top of the U-shaped frame and is fixedly connected to a printing nozzle.
[0010] As a preferred technical solution of this application, the adjusting component includes a mounting frame, which is fixedly connected to the top of the support plate. A bidirectional screw is rotatably connected to the inner cavity of the mounting frame, and moving blocks are threaded to both ends of the side wall of the bidirectional screw. A guide plate is fixedly connected to the bottom of the moving blocks.
[0011] As a preferred technical solution of this application, a turntable is rotatably connected to the side wall of the mounting frame. The turntable is fixed to one end of a bidirectional screw. A positioning rod is slidably connected to the side wall of the turntable. A spring is fixedly connected between one end of the positioning rod and the turntable. A positioning hole matching the positioning rod is opened on the side wall of the mounting frame.
[0012] As a preferred technical solution of this application, the driving component includes a threaded rod, the top of the fixed plate is provided with a support groove for supporting the threaded rod, the outer side wall of the threaded rod is threadedly connected with a threaded block, and the top of the threaded block is fixedly connected to the moving plate.
[0013] As a preferred technical solution of this application, a second motor for driving the threaded rod to rotate is fixedly connected to the side wall of the fixing plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] In the scheme of this application:
[0016] 1. The moving plate is moved horizontally by the driving component. Since the movable rod and the slider are fixedly connected, the slider slides on the slide bar on the moving plate, and the movable rod slides obliquely on the support plate through the slide groove. When the moving plate moves, it can push the movable rod to move. At this time, the movable rod drives the slider to slide on the slide bar and moves the movable rod in the slide groove. Four sets of movable rods drive four sets of limit wheels to position the half shaft gear. The first motor drives the limit wheels to rotate, and the limit wheels drive the half shaft gear to rotate. Thus, the half shaft gear can be rotated and adjusted according to the diverse printing needs of the half shaft gear, improving the printing efficiency of the half shaft gear marking.
[0017] 2. The rotating turntable drives the bidirectional screw to rotate, which in turn drives the moving blocks at both ends to move relative to each other. The moving blocks drive the guide plates to move relative to each other, and the guide plates position the half-shaft gear to prevent the half-shaft gear from shifting during the conveying process, making it convenient to use.

A driving component for driving the movable plate 210 to translate is provided on the fixed plate 200.
[0028] Please see Figure 1 The printing component includes a U-shaped frame 120, which is fixedly connected to one end of the top of the support plate 110. A telescopic cylinder 130 is fixedly connected to the top of the U-shaped frame 120.

Moving blocks 320 are threadedly connected to both ends of the side wall of the bidirectional screw 310. A guide plate 330 is fixedly connected to the bottom of the moving blocks 320. The rotation of the bidirectional screw 310 drives the two sets of moving blocks 320 to move relative to each other. The moving blocks 320 drive the guide plate 330 to move horizontally. The guide plate 330 limits and guides the half-shaft gear, so that the half-shaft gear is in the middle of the worktable 100.
[0030] Please see Figure 1 , Figure 2 and Figure 4 A turntable 340 is rotatably connected to the side wall of the mounting frame 300. The turntable 340 is fixed to one end of the bidirectional screw 310. A positioning rod 350 is slidably connected to the side wall of the turntable 340.

[0033] Specifically, in use, the half-shaft gear marking and printing device is first powered on. The positioning rod 350 is pulled out of the positioning hole. Then, the turntable 340 is rotated, causing the bidirectional screw 310 to rotate. The bidirectional screw 310 then moves the moving block 320, which in turn moves the guide plate 330, thus adjusting the distance between the two sets of guide plates 330. Next, the half-shaft gear is placed on the transmission belt on the worktable 100, and then positioned by the guide plate 330. When the half-shaft gear moves to the printing nozzle 131, the second motor 27... The first motor 142 drives the threaded rod 250 to rotate, which in turn drives the threaded block 260 and the moving plate 210 to translate. The slider 240 on the moving plate 210 pushes the movable rod 140 to slide on the slide groove 111. The limiting wheel 141 on the movable rod 140 limits the half-shaft gear.
