Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically a marking device for machined parts. Background Technology

[0002] In the machining field, materials with similar shapes are frequently encountered, such as angle steel profiles with the same specifications and length but different hole positions. To address this issue, manual measurement and classification are typically used in actual production. However, manual measurement and classification are prone to errors, are inefficient, and lack any labeling of the classified materials, resulting in poor traceability of the finished products. This can easily lead to product quality problems and customer complaints. Currently, there is no marking device that can effectively hold the machined parts in place for marking operations.

[0003] Chinese Patent (Announcement No.: CN208343710U) discloses a marking device for machined parts. A support base has an opening for the workpiece to enter, and a limiting component is provided at the end of the opening. A marking machine is located above the support base, with upper clamping plates spanning the opening on both sides of the marking machine. A pneumatic component is located below the support base corresponding to the marking machine, and a lower clamping plate for placing the workpiece is located at the output shaft end of the pneumatic component. The lower clamping plate can move to fit against the upper clamping plate to clamp the workpiece. The machined part marking machine provided by this utility model can effectively fix the workpiece, thus enabling fast and accurate marking operations. The setting of the conveying component and the limiting component facilitates adjustment of the workpiece's position within the opening, allowing the device to mark workpieces of various specifications and improving marking efficiency. However, this device lacks an auxiliary unloading mechanism after marking, making it inconvenient to use.

[0004] To address the aforementioned issues, we have made improvements and proposed a marking device for machined parts. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model provides a marking device for machined parts, including a worktable. A mounting frame is fixedly connected to the top center of the worktable, and a marking machine body is fixedly installed at the top center of the mounting frame. A through-hole groove is opened at the top center of the worktable. A lifting mechanism is installed at the bottom of the worktable. A support plate is fixedly connected to the output end of the lifting mechanism. A placement plate is hinged to the top of the support plate and is disposed inside the through-hole groove. The rear side of the placement plate protrudes from the support plate. A top plate is connected to a fixed rod at the bottom rear side of the worktable, and the top of the top plate is disposed below the placement plate protruding from the support plate. A material collection frame is provided at the bottom of the worktable and is disposed in front of the placement plate.

[0007] As a preferred embodiment of the present invention, the lifting mechanism includes a second motor, the output end of which is fixedly connected to a second threaded rod, and a pair of movable blocks are threadedly connected to the outer side of the second threaded rod.

[0008] As a preferred embodiment of this utility model, a conveyor belt is provided on the right side of the workbench, and the upper surface of the conveyor belt is flush with the workbench.

[0009] As a preferred embodiment of this utility model, an extension frame is fixedly connected to the top right side of the workbench, a first motor is fixedly installed at the right end of the extension frame, a first threaded rod is fixedly connected to the output end of the first motor, a connecting arm is threadedly connected to the outer side of the first threaded rod, and a push plate is fixedly connected to the bottom of the connecting arm.

[0010] As a preferred embodiment of this utility model, a pair of guide plates are fixedly connected to the top of the workbench, and the guide plates are disposed between the conveyor belt and the through-hole groove.

[0011] As a preferred embodiment of this utility model, cylinders are fixedly installed on both the front and rear sides of the mounting frame, and clamping plates are fixedly connected to the output ends of the cylinders.

[0012] As a preferred embodiment of this utility model, the end of the placement plate is provided with a stepped groove, and the stepped groove cooperates with the through hole groove.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, the lifting mechanism causes the support plate and the placement plate to descend. As the placement plate descends, the rear side of the placement plate contacts the top material plate, causing the placement plate to tilt.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figure 1 - Figure 3 As shown, a marking device for machined parts includes a worktable 1, a mounting frame 2 fixedly connected to the top center of the worktable 1, a marking machine body 3 fixedly mounted on the top center of the mounting frame 2, a through hole groove 9 opened in the top center of the worktable 1, a lifting mechanism installed at the bottom of the worktable 1, a support plate 20 fixedly connected to the output end of the lifting mechanism, a placement plate 10 hinged to the top of the support plate 20, and the placement plate 10 is disposed inside the through hole groove 9, the rear side of the placement plate 10 protrudes from the support plate 20, a top plate 22 is connected to the bottom rear side of the worktable 1 with a fixed rod, and the top of the top plate 22 is disposed below the placement plate 10 protruding from the support plate 20, and a material collection frame 11 is disposed at the bottom of the worktable 1, and the material collection frame 11 is disposed in front of the placement plate 10.

[0023] The workpiece is placed on the top of the placement plate 10, and the main body 3 of the marking machine performs a marking operation on the workpiece. After the marking is completed, the lifting mechanism works to make the support plate 20 and the placement plate 10 descend. As the placement plate 10 descends, the rear side of the placement plate 10 contacts the top material plate 22, causing the placement plate 10 to tilt. After the placement plate 10 tilts at a certain angle, the lifting mechanism stops working, and the workpiece slides forward along the placement plate 10 and falls into the collection frame 11 to assist in unloading and make it more convenient to use.

[0024] Specifically, such as Figure 2As shown, the lifting mechanism includes a second motor 16, and a second threaded rod 17 is fixedly connected to the output end of the second motor 16. The second threaded rod 17 is a bidirectional threaded rod, and a pair of movable blocks 18 are threadedly connected to the outer side of the second threaded rod 17. The top of each pair of movable blocks 18 is hinged to a push rod 19, and the top of each pair of push rods 19 is hinged to the bottom of the support plate 20. When the second motor 16 works, it drives the second threaded rod 17 to rotate. The rotating second threaded rod 17 drives the two movable blocks 18 to move towards each other or away from each other, thereby adjusting the height of the support plate 20.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, a conveyor belt 4 is provided on the right side of the workbench 1, and the upper end of the conveyor belt 4 is flush with the workbench 1. An extension frame 5 is fixedly connected to the top right side of the workbench 1. A first motor 12 is fixedly installed at the right end of the extension frame 5. A first threaded rod 13 is fixedly connected to the output end of the first motor 12. A connecting arm 14 is threadedly connected to the outer side of the first threaded rod 13. A push plate 15 is fixedly connected to the bottom of the connecting arm 14. An infrared sensor is provided at the end of the extension frame 5 to detect whether a workpiece has arrived under the extension frame 5, thereby controlling the first motor 12 and the conveyor belt 4 to work. When the workpiece arrives on the workbench 1 along the conveyor belt 4, the first motor 12 drives the first threaded rod 13 to rotate. The first threaded rod 13 drives the connecting arm 14 and the push plate 15 to move through the thread, thereby pushing the workpiece from the conveyor belt 4 onto the placement plate 10, which is convenient for auxiliary material feeding.

[0026] Specifically, such as Figure 1 As shown, a pair of guide plates 6 are fixedly connected to the top of the workbench 1, and the guide plates 6 are set between the conveyor belt 4 and the through hole groove 9. The workpiece reaches the placement plate 10 through the guide plates 6 for workpiece correction.

[0027] Specifically, such as Figure 1 As shown, cylinders 7 are fixedly installed on both the front and rear sides of the mounting frame 2. The output end of the cylinder 7 is fixedly connected to the clamping plate 8. After the workpiece arrives on the placement plate 10, the cylinder 7 works to make the clamping plate 8 clamp the workpiece and fix it.

[0028] Specifically, such as Figure 3 As shown, a stepped groove 21 is provided at the end of the placement plate 10, and the stepped groove 21 cooperates with the through hole groove 9. The stepped groove 21 and the through hole groove 9 are used to fix the placement plate 10 and prevent the placement plate 10 from tilting.

[0029] Working principle: The workpiece arrives at the worktable 1 along the conveyor belt 4. The first motor 12 drives the first threaded rod 13 to rotate. The first threaded rod 13 drives the connecting arm 14 and the push plate 15 to move through the thread, thereby pushing the workpiece from the conveyor belt 4 onto the placement plate 10. The cylinder 7 works to make the clamping plate 8 clamp the workpiece. The marking machine body 3 performs marking operation on the workpiece. After marking is completed, the second motor 16 works to drive the second threaded rod 17 to rotate. The rotating second threaded rod 17 drives the two movable blocks 18 to move in opposite directions, causing the support plate 20 and the placement plate 10 to descend. As the placement plate 10 descends, the rear side of the placement plate 10 contacts the top material plate 22, causing the placement plate 10 to tilt. After the placement plate 10 tilts at a certain angle, the lifting mechanism stops working, and the workpiece slides forward along the placement plate 10 and falls into the collection frame 11.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
