Description

Technical Field

[0001] This utility model relates to the field of machine tool processing auxiliary equipment technology, specifically to an automatic workpiece feeding mechanism for machine tool processing. Background Technology

[0002] In the machine tool processing production process, the workpiece loading process is a key step to ensure processing efficiency and production continuity. Currently, the workpiece loading methods for machine tool processing are mainly divided into two categories: manual loading and semi-automatic / fully automatic mechanism loading.

[0003] Manual feeding requires operators to manually move workpieces to the processing station, which is not only labor-intensive and inefficient, making it difficult to adapt to the needs of high-speed automated processing production lines, but also poses a safety hazard of operators accidentally touching the processing equipment. Existing semi-automatic or fully automatic feeding mechanisms are mostly complex in structure and have high manufacturing costs, and are poorly adaptable to different specifications of workpieces. When different types of shafts and rods need to be processed, the mechanism often needs to be significantly adjusted, resulting in a long debugging cycle and affecting production efficiency.

[0004] In addition, the feeding stability of some existing feeding mechanisms is insufficient, which can easily lead to problems such as workpiece jamming and simultaneous feeding of multiple parts, resulting in a decrease in processing accuracy and an increase in product defect rate.

[0005] Therefore, developing an automatic workpiece feeding mechanism for machine tool processing with simple structure, strong adaptability, stable feeding and high degree of automation has become an urgent technical problem to be solved in the current machine tool processing field. Summary of the Invention

[0006] This utility model aims to solve one of the technical problems existing in the prior art.

[0007] This application provides an automatic workpiece feeding mechanism for machine tool processing, including a mounting frame with a storage shell, a blocking unit and a delivery unit. The storage shell is used to store workpieces in an orderly stack along the height direction. The blocking unit can extend into or out of the bottom of the storage shell between two adjacent workpieces to control the orderly falling of individual workpieces in the storage shell. The delivery unit is used to receive the falling workpieces and deliver them to the feeding station or the feeding end of an external processing equipment.

[0008] The storage shell includes a receiving groove and a pair of half-shells. The pair of half-shells are fixed on the mounting frame by corresponding connecting rods, forming a semi-closed receiving groove between them. The middle of the receiving groove is open on both sides, and the two ends are used to receive the ends of the workpiece.

[0009] The blocking unit includes a linear driver and a partition. The linear driver is fixed on the mounting frame, and the partition is fixed at its output end.

[0010] The partition is L-shaped and includes a vertical section and a horizontal section, wherein the vertical section is fixedly connected to the telescopic end of the linear actuator, and the horizontal section is used to extend into the gap between adjacent workpieces.

[0011] The horizontal section is provided with fork plates on both sides at the end away from the vertical section.

[0012] A clearance groove is provided on one side of the mounting bracket to accommodate the retracted partition.

[0013] The delivery unit includes a pallet and a pair of linear actuators, the first of which controls the pallet to rise and fall, and the other linear actuator controls the first linear actuator to move horizontally.

[0014] The delivery unit also includes a magnet, which is fixed to the tray.

[0015] The linear actuator is a cylinder.

[0016] The mounting frame includes a horizontal plate and a side plate, the horizontal plate and the side plate are fixedly connected, the storage shell and the interception unit are mounted on the horizontal plate, and the delivery unit is mounted on the side plate.

[0017] The beneficial effects of this utility model are as follows: 1. By integrating the storage shell, interception unit and delivery unit through the mounting frame, the entire process of "stacked storage - single-piece material control - precise delivery" of workpieces is fully automated without manual intervention, which effectively reduces the labor intensity of operators, improves material loading efficiency, and can meet the needs of high-speed automated processing production lines.

[0018] 2. The semi-enclosed receiving slot of the storage shell can effectively limit the workpiece and can adapt to shaft and rod workpieces of different lengths; the blocking unit, through the structural design of L-shaped partition and fork plate, realizes reliable support for the workpiece and orderly control of single-piece falling, avoiding material jamming or feeding disorder; the delivery unit uses magnets to attract and fix the workpiece, and with the precise drive of the cylinder, ensures that the workpiece does not slip or shift during the transfer process, further improving the stability and accuracy of feeding.

[0019] 3. Each functional unit adopts a modular layout design with reasonable installation positions and no interference between action areas, shortening the workpiece transfer path; at the same time, the modular structure facilitates the individual debugging, maintenance and replacement of each unit, reducing the maintenance cost and operation and maintenance difficulty of the equipment; in addition, the linear actuator uses a cylinder, which has the advantages of simple structure, fast response speed, stable output force and low cost, further improving the practicality and economy of the mechanism.

[0020] 4. The open design on both sides of the middle of the storage shell makes it easy for operators to observe the remaining storage of workpieces, facilitating timely replenishment and handling of jamming issues; the fully automated operation reduces the contact between operators and processing equipment, lowers safety hazards, and improves the safety of the production process.

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0024] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The automatic workpiece feeding mechanism for machine tool processing provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0026] Example 1: This application provides an automatic workpiece feeding mechanism for machine tool processing, including a mounting frame 1 with a storage shell 2, a blocking unit 3 and a delivery unit 4. The storage shell 2 is used to store workpieces in an orderly stacked manner along the height direction. The blocking unit 3 can extend into or out between two adjacent workpieces at the bottom of the storage shell 2 to control the orderly falling of individual workpieces in the storage shell 2. The delivery unit 4 is used to receive the falling workpieces and deliver them to the feeding station or the feeding end of an external processing equipment.

[0027] In this embodiment of the application, the storage shell 2 includes a receiving groove 23 and a pair of half shells 21. The pair of half shells 21 are fixed on the mounting frame 1 by corresponding connecting rods 22, forming a semi-closed receiving groove 23 between them. The receiving groove 23 is open on both sides in the middle, and the two ends are used to receive the ends of the workpiece.

[0028] like Figures 1 to 3 As shown, due to the above-mentioned structure, the semi-enclosed receiving groove 23 can effectively limit the stacked workpieces, preventing them from shifting or tipping over during the stacking process. The open design on both sides of the middle section facilitates the operator's observation of the remaining storage capacity of the workpieces and allows for quick handling when workpieces become stuck. At the same time, the receiving groove 23 structure at both ends, which is specifically designed to accommodate the ends of the workpieces, can be adapted to workpieces of different lengths, such as shafts and rods, further improving the versatility of the storage shell 2. This ensures that the workpieces are stacked in an orderly manner along the height direction, laying the foundation for the precise material control of the subsequent interception unit 3 and the stable material receiving of the delivery unit 4.

[0029] Example 2: In this embodiment, in addition to the structural features of the aforementioned embodiments, the blocking unit 3 includes a linear driver 31 and a partition 32. The linear driver 31 is fixed on the mounting frame 1, and the partition 32 is fixed at its output end.

[0030] In this embodiment of the application, the partition 32 is L-shaped and includes a vertical section 321 and a horizontal section 322, wherein the vertical section 321 is fixedly connected to the telescopic end of the linear actuator 31, and the horizontal section 322 is used to extend into the gap between adjacent workpieces.

[0031] In this embodiment of the application, fork plates 323 are provided on both sides of the horizontal segment 322 away from the vertical segment 321.

[0032] In this embodiment of the application, a clearance groove 11 is provided on one side of the mounting bracket 1 to accommodate the retracted partition 32.

[0033] like Figures 1 to 3As shown, due to the above structure, the linear actuator 31 can drive the partition 32 to achieve precise extension and retraction. The L-shaped partition 32 forms a stable force-bearing structure through the vertical section 321 and the horizontal section 322, ensuring that the horizontal section 322 can smoothly extend into or out of the gap between adjacent workpieces. The fork plates 323 on both sides of the horizontal section 322 increase the contact area with the workpiece, which can provide more reliable support for the workpiece and prevent the workpiece from tipping over or shifting during the interception process. The clearance groove 11 on the mounting frame 1 provides a space for the partition 32 to retract, effectively preventing the partition 32 from interfering with the mounting frame 1 or other components when retracting, making the operation of the interception unit 3 smoother, thereby realizing the orderly falling control of the workpieces in the storage shell 2 and preventing the problem of multiple pieces falling at the same time or the problem of material jamming or feeding disorder.

[0034] Example 3: In this embodiment, in addition to the structural features of the aforementioned embodiments, the delivery unit 4 includes a tray 41 and a pair of linear actuators 31. The first linear actuator 31 is used to control the tray 41 to rise and fall, and the other linear actuator 31 is used to control the first linear actuator 31 to move horizontally.

[0035] In this embodiment of the application, the delivery unit 4 further includes a magnet 42, which is fixed on the tray 41.

[0036] In this embodiment of the application, the linear actuator 31 is a cylinder.

[0037] like Figures 1 to 3 As shown, due to the above-mentioned structure, a pair of cylinders work together to precisely control the pallet 41 to complete the continuous action of "lifting, receiving, and horizontal feeding". The cylinder drive method has the characteristics of fast response speed and stable output force, which is suitable for the high-efficiency production requirements of machine tool processing. The magnet 42 on the pallet 41 can attract and fix the ferromagnetic workpiece, effectively preventing the workpiece from slipping or shifting during the lifting and horizontal movement of the pallet 41, and ensuring the stability and accuracy of workpiece delivery. At the same time, the selection of cylinders makes the structure of the delivery unit 4 simple and easy to maintain, reducing the operating cost of the equipment. It can stably deliver the falling workpiece to the designated loading station or the feeding end of the external processing equipment, realizing the automated connection of the loading process.

[0038] Example 4: In this embodiment, in addition to the structural features of the aforementioned embodiments, the mounting frame 1 includes a horizontal plate 12 and a side plate 13, the horizontal plate 12 and the side plate 13 are fixedly connected, the storage shell 2 and the interception unit 3 are mounted on the horizontal plate 12, and the delivery unit 4 is mounted on the side plate 13.

[0039] like Figures 1 to 3As shown, due to the above-mentioned structure, the mounting frame 1 formed by the fixed connection of the horizontal plate 12 and the side plate 13 is stable and has sufficient load-bearing capacity, providing a stable mounting reference for the storage shell 2, the interception unit 3, and the delivery unit 4 respectively. The layout design of integrating the storage shell 2 and the interception unit 3 on the horizontal plate 12 and installing the delivery unit 4 on the side plate 13 makes the installation position of each functional unit reasonable, and the action areas do not interfere with each other. It can realize the efficient connection of workpiece "storage-interception falling-receiving delivery", shortening the workpiece transfer path. At the same time, the modular installation layout also facilitates the individual debugging, maintenance and replacement of each unit, improving the assembly efficiency and later operation and maintenance convenience of the entire feeding mechanism, and ensuring the long-term stable operation of the mechanism.
