Description

Technical Field

[0001] This utility model relates to the technical field of workpiece feeding equipment, and in particular to a workpiece feeding and typing device. Background Technology

[0002] In the machining process of shaft-type workpieces, it is usually necessary to first print specific markings or fonts (such as part numbers) on the surface of the workpiece, and then transport it to the machining equipment for subsequent processing through the loading equipment.

[0003] However, most current loading equipment on the market lacks typing capabilities, forcing the typing and loading processes to be separated and performed independently. In practice, operators must first use a specialized typing device to print the markings on the workpieces, and then place the marked workpieces one by one into the loading equipment, which then transfers them to the processing equipment for processing. This step-by-step operation increases the complexity of the processing flow and causes numerous inconveniences in actual production. Summary of the Invention

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0024] like Figures 1 to 6 As shown, a workpiece feeding and typing device includes a frame 1, on which a guide rail 2, a workpiece waiting rack 6, and a workpiece positioning seat 9 are provided. A movable seat 3 is slidably mounted on the guide rail 2, and a top-loading rod 4 is mounted on the movable seat 3. The movable seat 3 is connected to a drive mechanism, which drives the movable seat 3 to move along the guide rail 2. The workpiece positioning seat 9 is provided with a workpiece positioning groove 20 and is located at the lower end of the workpiece waiting rack 6. A typing device is provided on one side of the workpiece positioning seat 9. The frame 1 is also provided with a stroke limiting mechanism, which switches between a positioning state and a non-positioning state. When the stroke limiting mechanism is in the positioning state, the stroke of the movable seat 3 is controlled by the stroke limiting mechanism so that the top-loading rod 4 pushes the workpiece 23 that has fallen into the workpiece positioning groove 20 onto the typing device.

[0025] This utility model integrates the functions of loading and typing. A typing device is directly installed on one side of the workpiece positioning seat 9. Through the coordinated action of the moving seat 3 and the top material rod 4, the workpiece loading and typing processes are integrated. Workpieces 23 are arranged in an orderly manner on the workpiece waiting rack 6. Workpieces 23 are ejected one by one from the lower end of the workpiece waiting rack 6, falling directly into the workpiece positioning groove 20 below. Then, the moving seat 3 is driven by a drive mechanism, which in turn drives the top material rod 4 forward, thus propelling the workpieces 23 forward. The process of propelling the workpieces 23 forward is divided into two stages. In the first stage, the stroke limiting mechanism switches to the positioning state. The stroke limiting mechanism in the positioning state controls the stroke of the moving seat 3, ensuring that the moving seat 3 moves to a specific stroke before... The process stops, at which point the ejector rod 4 pushes the workpiece 23 into the typing device, and the typing device performs typing operations on the surface of the workpiece 23. After the typing operation is completed, the process enters the second stage. In the second stage, the stroke limiting mechanism switches to the non-positioning state. At this time, the stroke limiting mechanism removes the restriction on the stroke of the moving seat 3. Then the moving seat 3 and the ejector rod 4 continue to move forward and push the workpiece 23 onto the processing equipment for subsequent processing. After completing the loading process of the previous workpiece 23, the moving seat 3 and the ejector rod 4 return to the initial position, and then the loading process of the next workpiece 23 is carried out in the same way.

[0026] The stroke limiting mechanism switches between a positioning state and a non-positioning state, controlling the movement stroke of the movable seat 3 according to production process requirements. In the positioning state, it strictly limits the displacement of the movable seat 3, ensuring that the ejector rod 4 precisely pushes the workpiece 23 in the workpiece positioning slot 20 to the preset position of the typing device, providing a prerequisite for accurate typing operations. In the non-positioning state, the stroke limiting mechanism releases the stroke restriction on the movable seat 3, allowing the movable seat 3 and ejector rod 4 to continue moving forward and complete the entire loading process of the workpiece 23.

[0027] This invention can automatically complete the typing operation on workpiece 23 during the loading process, which not only reduces the labor intensity of operators but also improves production efficiency. This integrated design shortens the process connection time, allowing workpiece 23 to seamlessly transfer during positioning, pushing, and typing, avoiding the waiting time for process switching in traditional methods.

[0028] The drive mechanism includes a first sprocket 10 rotatably connected to the frame 1, a motor 5 mounted on the frame 1, a second sprocket connected to the motor 5, and a transmission chain 11 connecting the first sprocket 10 and the second sprocket. The movable seat 3 is connected to the transmission chain 11. The length direction of the transmission chain 11 is parallel to the axial direction of the guide rail 2. The motor 5 drives the sprocket to rotate, which in turn drives the transmission chain 11 to move, thereby causing the movable seat 3 to move along the guide rail 2.

[0029] Specifically, the typing device includes a typing positioning seat 16, on which a typing positioning groove 17 for accommodating a workpiece 23 is provided. The typing positioning groove 17 and the workpiece positioning groove 20 are arranged on the same straight line. Above the typing positioning seat 16, a vertically movable stamping seat 18 is provided, and at the lower end of the stamping seat 18, a die 19 is provided. The stamping seat 18 is connected to a stamping cylinder, which drives the stamping seat 18 to move up and down. The lower end of the die 19 is provided with a protrusion of a specific shape. When typing on the workpiece 23, the workpiece 23 first enters the typing positioning groove 17, and then the stamping cylinder drives the die 19 to move downward. Through the stamping action of the die 19 on the surface of the workpiece 23, fonts or marks are formed on the surface of the workpiece 23.

[0030] In this application, the typing positioning groove 17 and the workpiece positioning groove 20 are arranged on the same straight line as the lathe spindle center; the workpiece in the workpiece positioning groove 20 will be directly fed into the typing positioning groove 17 in a straight line, which improves the feeding speed, reduces the number of processes, and the feeding process is stable and simple to operate.

[0031] When the subsequent processing equipment is a lathe, the spindle center of the lathe is aligned with the typing positioning groove 17 and the workpiece positioning groove 20. In this way, after the workpiece is typed, it will be pushed out of the typing positioning groove 17 and directly enter the subsequent lathe for processing.

[0032] In this application, the cross-section of workpiece 23 is hexagonal, the cross-section of workpiece positioning groove 20 is rectangular, and the cross-section of typing positioning groove 17 is hexagonal.

[0033] The frame 1 is equipped with a pressure arm 21, which is hinged to the frame 1 at its middle. One end of the pressure arm 21 is a connecting end 21a, and a spring 22 is installed between the connecting end 21a and the frame 1. The other end of the pressure arm 21 is a pressure end 21b, which is located above the workpiece positioning groove 20. When the workpiece 23 passes under the pressure end 21b, the pressure end 21b applies downward pressure to the workpiece 23. Since the cross-section of the workpiece positioning groove 20 is rectangular, while the cross-section of the workpiece 23 is hexagonal, there is a difference in their shapes. After the workpiece 23 falls into the workpiece positioning groove 20, there may be a risk of slight shaking or positional displacement. The pressure end 21b of the pressure arm 21 is located above the workpiece positioning groove 20. When the workpiece 23 passes under the pressure end 21b, the pressure end 21b applies downward pressure to the workpiece 23 under the elastic force of the spring 22. This effectively presses the workpiece 23 firmly into the workpiece positioning groove 20, preventing the workpiece 23 from shaking or shifting and causing positional deviations when the ejector rod 4 pushes it. This ensures that the workpiece 23 falls accurately into the typing positioning groove 17. The cross-section of the typing positioning groove 17 is a hexagon that matches the workpiece 23, requiring higher positioning accuracy for the workpiece 23. During the process of the ejector rod 4 pushing the workpiece 23 from the workpiece positioning groove 20 into the typing positioning groove 17, the continuous pressure of the pressure arm 21 can constrain the posture of the workpiece 23, preventing the workpiece 23 from flipping or tilting during pushing. This allows the workpiece 23 to smoothly and accurately enter the typing positioning groove 17 and fit into the groove, laying the foundation for the accuracy of subsequent stamping and typing.

[0034] A steel ball 21c is provided at the lower end of the pressure-applying end 21b. When the pressure arm 21 applies pressure to the workpiece 23, the steel ball 21c contacts the upper surface of the workpiece 23. The steel ball 21c contacts the workpiece 23 through its spherical surface, allowing the workpiece 23 to pass smoothly under the pressure-applying end 21b, avoiding jamming or obstruction during the movement of the workpiece 23.

[0035] The stroke limiting mechanism includes a cylinder 14 and a swing arm 13. A bracket 12 for connecting the cylinder 14 is provided on the frame 1. One end of the cylinder 14 is hinged to the bracket 12, and the other end of the cylinder 14 is hinged to one end of the swing arm 13. The other end of the swing arm 13 is hinged to the frame 1. A positioning element 15 is provided on the swing arm 13. The swing arm 13 is driven to rotate by the cylinder 14 so that the stroke limiting mechanism switches between a positioning state and a non-positioning state. When the stroke limiting mechanism is in the positioning state, the swing arm 13 rotates to a specific angle, causing the positioning element 15 to enter the movement path of the moving seat 3, forming a mechanical block on the stroke of the moving seat 3. This precisely controls the ejector rod 4 to push the workpiece 23 from the positioning slot into the preset position of the typing device, ensuring the positioning accuracy of the typing process. When switching to the non-positioning state, the cylinder 14 drives the swing arm 13 to rotate in the opposite direction, causing the positioning element 15 to disengage from the movement path of the moving seat 3, releasing the stroke limitation on the moving seat 3, allowing the ejector rod 4 to continue moving with the moving seat 3, completing the conveying of the workpiece 23 from the typing device to the next process (such as feeding it into the processing equipment).

[0036] In this embodiment, the positioning element 15 is a bolt threaded onto the swing arm 13. The length of the bolt extending out of the swing arm 13 can be adjusted by rotating the bolt, that is, adjusting the blocking position of the bolt end on the movement path of the moving seat 3.

[0037] A side cover 7 is provided on the frame 1, and a top cover 8 is connected to the upper end of the side cover 7. The top cover 8 is hinged to the side cover 7.

[0038] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
