Description

Technical Field

[0001] This utility model relates to the technical field of automatic workpiece loading and unloading devices, and more specifically, to an automatic workpiece loading and unloading device for machine tools. Background Technology

[0002] Automatic workpiece loading and unloading devices for machine tools are automated equipment used to automatically load and unload workpieces during processing, improving production efficiency and reducing manual intervention. These devices are widely used in automated production lines such as CNC machine tools and machining centers.

[0003] Automatic workpiece loading and changing is achieved through a gripper cylinder. The gripper cylinder is equipped with a spring feeding device, which holds the workpiece in place by the spring to prevent it from being pulled away when the gripper moves. However, the existing spring feeding device has a limited coverage range. When the workpiece size exceeds the coverage range, the spring feeding device needs to be replaced, which is time-consuming and labor-intensive and affects production efficiency.

[0004] In view of this, we will study and improve the existing problems and provide an automatic workpiece loading and unloading device for machine tools. The aim is to solve the problems and improve the practical value through this technology. Utility Model Content

[0005] The purpose of this invention is to provide an automatic workpiece loading and unloading device for machine tools, so as to solve the problems and deficiencies mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides an automatic workpiece loading and unloading device for machine tools, which is achieved by the following specific technical means:

[0007] An automatic workpiece loading and unloading device for a machine tool includes: a mounting base, a rotary cylinder, a rotary seat, a gripper cylinder, a gripper, a spring feeding device, a fixed plate, a guide rod, a spring, a feeding plate, and a connecting plate. The rotary cylinder is fixedly mounted on the bottom of the mounting base, and the rotary seat is fixedly mounted on the output end of the rotary cylinder. The gripper cylinder is fixedly mounted on the rotary seat, and the gripper is fixedly mounted on the output end of the gripper cylinder. The spring feeding device includes a fixed plate, one end of which is fixedly mounted on the gripper cylinder, and the other end of which is slidably mounted with a guide rod. A spring is sleeved on the guide rod, and the feeding plate is fixedly mounted on the other end of the guide rod. The connecting plate is movably mounted on the guide rod via a sleeve connection, and the connecting plate is located between the spring and the feeding plate.

[0008] As a further optimization of this technical solution, the overall appearance of the rotating seat of the automatic workpiece loading and unloading device for machine tools of this utility model is a right-angled triangle, and a gripper cylinder is provided on both right-angled surfaces of the rotating seat, and the axis lines of the two gripper cylinders are perpendicular.

[0009] As a further optimization of this technical solution, the gripper cylinder of the automatic workpiece loading and unloading device for machine tools of this utility model is provided with multiple fixed plates, and the guide rods at the ends of the multiple fixed plates are connected into one piece by connecting plates.

[0010] As a further optimization of this technical solution, the outer wall of the connecting plate of the automatic workpiece loading and unloading device for machine tools of this utility model is provided with a groove for installing a feeding plate, and a stop edge for limiting the feeding plate is provided on one side of the groove.

[0011] As a further optimization of this technical solution, the outer wall of one end of the connecting plate of the automatic workpiece loading and unloading device for machine tools of this utility model is provided with anti-slip stripes distributed in a ring array, and the anti-slip groove is located around the guide rod, and the same anti-slip stripes are provided at the position where the feeding plate abuts against the anti-slip stripes.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0013] 1. The overall appearance of the rotating seat of this utility model is a right-angled triangle, and a gripper cylinder is provided on each of the two right-angled surfaces of the rotating seat. The axis of the two gripper cylinders is set perpendicularly. The two gripper cylinders respectively complete the loading and unloading operations, and drive the rotating seat to rotate through the rotating cylinder, so that the two gripper cylinders exchange positions, thereby completing the automatic loading and unloading of workpieces.

[0014] 2. A guide rod is slidably provided at the other end of the fixed plate of this utility model, and the feeding plate is fixedly installed at the other end of the guide rod. A groove for installing the feeding plate is provided on the outer wall of the connecting plate, which realizes the rotation of the feeding plate. The feeding plate can be unfolded and folded by rotation. After unfolding, the overall length is further extended and the coverage area is increased, which is suitable for feeding workpieces of different sizes. The groove on the outer wall of the connecting plate is used to accommodate the feeding plate for easy storage. The retaining edge plays a limiting role for the feeding plate and prevents the feeding plate from leaking out.

[0015] 3. The outer wall of one end of the connecting plate of this utility model is provided with anti-slip stripes distributed in a ring array, and the anti-slip groove is located around the guide rod. The same anti-slip stripes are provided at the position where the feeding plate abuts against the anti-slip stripes. The anti-slip stripes increase the friction between the connecting plate and the feeding plate, making the feeding plate less likely to move during use. At the same time, the spring provides elastic support for the connecting plate, so that the connecting plate and the feeding plate are tightly attached and the two always maintain friction.

[0016] 4. This utility model improves the automatic workpiece loading and unloading device for processing machine tools, and has the advantages of reasonable structural design, flexible structure, and the ability to expand the coverage of the feeding device by unfolding. It is suitable for feeding workpieces of different sizes and has strong practicality, thus effectively solving the problems and shortcomings of existing technologies and equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 4 This utility model provides a specific technical implementation scheme for an automatic workpiece loading and unloading device for machine tools:

[0025] An automatic workpiece loading and unloading device for a machining tool includes: a mounting base 1, a rotary cylinder 2, a rotary seat 3, a gripper cylinder 4, grippers 5, a spring feeding device 6, a fixing plate 601, a guide rod 602, a spring 603, a feeding plate 604, a connecting plate 605, and a retaining edge 606. The rotary cylinder 2 is fixedly mounted at the bottom of the mounting base 1, and the rotary seat 3 is fixedly mounted at the output end of the rotary cylinder 2. The rotary seat 3 has a right-angled triangular shape, and gripper cylinders 4 are provided on both right-angled surfaces of the rotary seat 3. The axis lines of the two gripper cylinders 4 are perpendicular. The two gripper cylinders 4 respectively complete the loading and unloading operations, and drive the rotary seat 3 to rotate through the rotary cylinder 2, so that the two gripper cylinders 4 interchange positions, thereby completing the automatic loading and unloading of workpieces.

[0026] The gripper 5 is fixedly installed at the output end of the gripper cylinder 4; the spring feeding device 6 includes a fixing plate 601, one end of which is fixedly installed on the gripper cylinder 4, and multiple fixing plates 601 are evenly distributed on the gripper cylinder 4. A guide rod 602 is slidably installed on the other end of the fixing plate 601; a spring 603 is sleeved on the guide rod 602, and a feeding plate 604 is fixedly installed on the other end of the guide rod 602. The rotation of the guide rod 602 realizes the rotation of the feeding plate 604, and the feeding plate 604 unfolds and folds by rotation. After unfolding, the overall length is further extended, and the coverage area is increased, which is suitable for feeding workpieces of different sizes.

[0027] The connecting plate 605 is movably mounted on the guide rod 602 by means of a sleeve connection, and the connecting plate 605 is located between the spring 603 and the feeding plate 604. The guide rods 602 at the ends of multiple fixed plates 601 are connected as one unit through the connecting plate 605. The spring 603 provides elastic support for the connecting plate 605, so that the connecting plate 605 and the feeding plate 604 are tightly fitted and the two always maintain friction.

[0028] The outer wall of the connecting plate 605 is provided with a groove for installing the feeding plate 604. A retaining edge 606 is provided on one side of the groove for limiting the feeding plate 604. The groove on the outer wall of the connecting plate 605 is used to accommodate the feeding plate 604 for easy storage. The retaining edge 606 limits the feeding plate 604 and prevents the feeding plate 604 from leaking out.

[0029] The outer wall of one end of the connecting plate 605 is provided with anti-slip stripes distributed in a ring array, and the anti-slip groove is located around the guide rod 602. The feeding plate 604 is provided with the same anti-slip stripes at the position where it abuts the anti-slip stripes. The anti-slip stripes increase the friction between the connecting plate 605 and the feeding plate 604, making the feeding plate 604 less likely to move during use.

[0030] Specific implementation steps:

[0031] The entire assembly is installed via mounting base 1. When gripping a workpiece, the gripper 5 located at the bottom of the rotary base 3 moves above the workpiece, and the gripper cylinder 4 pushes the gripper 5 to unfold and grip the workpiece, moving the workpiece to the processing position. The gripper 5 located on the other side of the rotary base 3 unfolds and grips the workpiece on the spindle. Then, the rotary cylinder 2 drives the rotary base 3 to rotate, changing the position of the two workpieces and placing the new workpiece on the spindle. During the placement process, the spring 603 provides elastic support to the connecting plate 605, ensuring that the feeding plate 604 is always pressed against the workpiece to prevent it from falling off. When the size of the workpiece being loaded or unloaded is large, the feeding plate 604 can be rotated and unfolded to increase the overall coverage area, thus making it suitable for feeding workpieces of different sizes.

[0032] In summary, this automatic workpiece loading and unloading device for the machining tool features a rotary table with a right-angled triangular shape. Two gripper cylinders are mounted on the two right-angled surfaces, their axes perpendicular to each other. Each gripper cylinder performs loading and unloading operations, and the rotary table rotates via a rotary cylinder, causing the two gripper cylinders to interchange positions, thus automatically loading and unloading workpieces. A guide rod slides along the other end of a fixed plate, and a feeding plate is fixedly mounted on the other end of the guide rod. A groove on the outer wall of the connecting plate allows for the feeding plate to rotate, unfolding and folding. When unfolded, the overall length is extended, increasing the coverage area and making it suitable for feeding workpieces of different sizes. The groove on the outer wall of the connecting plate accommodates the feeding plate. The feeding plate is easy to store, and the edge stops the feeding plate to prevent it from leaking out. The outer wall of one end of the connecting plate has annularly arrayed anti-slip stripes, and anti-slip grooves are located around the guide rod. The feeding plate also has the same anti-slip stripes at the point where they abut. These anti-slip stripes increase the friction between the connecting plate and the feeding plate, making the feeding plate less prone to movement during use. Simultaneously, springs provide elastic support to the connecting plate, ensuring a tight fit between them and maintaining constant friction. This improvement to the automatic workpiece loading and unloading device for machine tools offers advantages such as a reasonable and flexible structure, the ability to expand the feeding device's coverage area by unfolding, suitability for feeding workpieces of different sizes, and high practicality. It effectively solves the problems and shortcomings of existing technologies and equipment.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
