Description

Technical Field

[0001] This utility model relates to the field of punching machine technology, specifically a self-positioning punching machine with automatic loading and unloading. Background Technology

[0002] A punching machine, also known as a punch forming machine, forming machine, grinding machine, or abrasive, is a mechanical device installed on machine tools such as grinding machines, milling machines, and drilling machines. It is used for forming and grinding various angles such as arcs, polygons, and circles. When used with a stone cleaning brush, it can be used to dress grinding wheels, punches, and center pins.

[0003] For example, patent CN112338651A discloses a punching machine, which includes a first drive mechanism and a second drive mechanism mounted on a frame. A grinding wheel for polishing is mounted on the first drive mechanism, and a punch head is mounted on the second drive mechanism. A part to be processed is fixedly fitted onto the punch head. When processing the part, the second drive mechanism is first moved to a set position. The first drive mechanism drives the grinding wheel to rotate, and the second drive mechanism drives the punch head, thereby causing the part to be processed to rotate. The grinding wheel polishes the part. This configuration improves the automation level of the punching machine, reduces labor intensity, minimizes labor waste, and increases processing efficiency. However, during the use of the punching machine, materials need to be placed manually. Workers manually place materials one by one inside the punching machine or on a specific placement platform to prepare for subsequent processing. This process is usually slow, and manual operation is easily affected by individual skill levels, work conditions, and other factors. There are also significant differences between different workers, and material supply may be untimely, making rapid loading and unloading difficult.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing punching machine. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic loading and unloading self-positioning punch machine to solve the problems mentioned in the background art, such as the fact that manual operation is easily affected by factors such as individual skill level and working status, and there are also large differences between different workers, and the material supply may be untimely, making it difficult to achieve rapid loading and unloading.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic loading and unloading self-positioning punch machine, including a base, a punch machine body fixedly connected to one side of the top of the base, a material bin fixedly connected to the other side of the top of the base, a conveyor belt installed inside the base, and a drive module for driving the conveyor belt installed on one side of the base.

[0007] A drive motor is fixedly connected to one side of the bottom of the hopper. A rotating shaft is fixedly connected to the output end of the drive motor. A feeding cylinder is fixedly connected to the outer wall of the rotating shaft. An arc-shaped opening is provided on the feeding cylinder. The feeding cylinder is located inside the hopper. A feeding port corresponding to the arc-shaped opening is provided at the bottom of the hopper.

[0008] The rotating shaft is equipped with a clamping mechanism for clamping materials.

[0009] Furthermore, the clamping mechanism includes two first synchronous pulleys, which are fixedly and staggered at one end of the rotating shaft. Support frames are installed on both sides of the base. A drive shaft is rotatably connected inside the support frames. A second synchronous pulley is fixedly connected to the outer wall of the drive shaft. Synchronous belts are provided between the two first synchronous pulleys and the two second synchronous pulleys respectively. An eccentric wheel is fixedly connected to one end of the drive shaft. A connecting rod is rotatably connected to one side of the eccentric wheel. A sliding clamping block is rotatably connected to one end of the connecting rod. A sliding seat is fixedly connected to one side of the base. The sliding clamping block is slidably connected inside the sliding seat.

[0010] Furthermore, a material feeding mechanism for collecting materials is provided below the base.

[0011] Furthermore, the feeding mechanism includes an inclined baffle, which is fixedly connected to the inside of the base. An inclined plate is also provided inside the base, and a collection box is provided below the inclined baffle.

[0012] Furthermore, the inclined plates and inclined baffles are staggered vertically.

[0013] Furthermore, the sliding clamping block is L-shaped.

[0014] Furthermore, the two connecting rods are positioned on the side where the two eccentric wheels are close to each other.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This automatic loading and unloading self-positioning punch machine drives the loading cylinder to rotate via a drive motor. By utilizing the arc-shaped opening of the loading cylinder and the loading port at the bottom of the hopper, the material is automatically loaded from the hopper to the conveyor belt. The material is then transported separately by the conveyor belt, reducing manual intervention, improving loading efficiency, reducing labor costs, and avoiding operational errors and instability that may occur with manual loading.

[0017] Furthermore, the clamping mechanism on the rotating shaft utilizes the coordinated work of components such as synchronous pulleys, synchronous belts, eccentric pulleys, and connecting rods. The rotation of the synchronous pulleys drives the transmission shaft to rotate, which in turn drives the eccentric pulleys and connecting rods to rotate, enabling the two connecting rods to move in opposite directions. This achieves automatic clamping and positioning of materials on the conveyor belt, accurately clamping the materials from the conveyor belt. Furthermore, the processing position of the punch machine body ensures the accuracy and consistency of processing, thereby improving product quality.

[0018] Furthermore, the inclined baffles and inclined plates in the feeding mechanism guide the processed materials to the collection box, realizing automatic feeding and material collection. The entire process requires no frequent manual operation, improving the continuity and efficiency of the production process, reducing the time intervals required for manual feeding and positioning, and greatly improving production efficiency.

Detailed Implementation

[0026] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: an automatic loading and unloading self-positioning punch machine, including a base 1, a punch machine body 2 fixedly connected to one side of the top of the base 1, a hopper 3 fixedly connected to the other side of the top of the base 1, a conveyor belt 6 installed inside the base 1, and a drive module for driving the conveyor belt 6 installed on one side of the base 1; a drive motor 4 fixedly connected to one side of the bottom of the hopper 3, a rotating shaft 17 fixedly connected to the output end of the drive motor 4, a feeding cylinder 5 fixedly connected to the outer wall of the rotating shaft 17, an arc-shaped opening on the feeding cylinder 5, the feeding cylinder 5 being disposed inside the hopper 3, and a feeding port corresponding to the arc-shaped opening being opened at the bottom of the hopper 3; a useful... A clamping mechanism for clamping materials; the clamping mechanism includes two first synchronous wheels 7, which are fixedly and staggered at one end of a rotating shaft 17. Support frames 10 are installed on both sides of the base 1. A transmission shaft 9 is rotatably connected inside the support frame 10. A second synchronous wheel 8 is fixedly connected to the outer wall of the transmission shaft 9. Synchronous belts are provided between the two first synchronous wheels 7 and the two second synchronous wheels 8 respectively. An eccentric wheel 11 is fixedly connected to one end of the transmission shaft 9. A connecting rod 12 is rotatably connected to one side of the eccentric wheel 11. A sliding clamping block 14 is rotatably connected to one end of the connecting rod 12. A sliding seat 13 is fixedly connected to one side of the base 1. The sliding clamping block 14 is slidably connected inside the sliding seat 13.

[0028] When in use, the drive module can drive the conveyor belt 6 to run inside the base 1. The hopper 3 is used to store the materials to be processed. After the drive motor 4 is started, its output end drives the rotating shaft 17 to rotate, and the feeding cylinder 5 on the outer wall of the rotating shaft 17 rotates accordingly. The arc-shaped opening on the feeding cylinder 5 corresponds to the feeding port at the bottom of the hopper 3. When the arc-shaped opening rotates to the discharge port of the hopper 3, the material in the hopper 3 will fall into the arc-shaped opening. Then the feeding cylinder 5 rotates, and when the arc-shaped opening gradually overlaps with the feeding port, the material in the arc-shaped opening falls from the discharge port onto the conveyor belt 6, realizing automatic feeding. When the rotating shaft 17 rotates, it drives the two first synchronous wheels 7, which are fixed at one end of the shaft, to rotate. The first synchronous wheels 7 drive the second synchronous wheels 8 to rotate through the synchronous belt. Since the second synchronous wheels 8 are fixed to the outer wall of the transmission shaft 9, the transmission shaft 9 rotates within the support frame 10. One end of the transmission shaft 9 is fixedly connected to an eccentric wheel 11. After the eccentric wheel 11 rotates, it drives the sliding clamping block 14 to slide inside the sliding seat 13 through the connecting rod 12. The two eccentric wheels 11 enable the two sliding clamping blocks 14 to move relative to or away from each other. When the two sliding clamping blocks 14 move relative to each other, they can clamp the material on the conveyor belt 6. At this time, the sliding clamping blocks 14 do not clamp the end of the material, but rather the middle or tail of the material, so that the end of the material can be aligned with the processing tool on the punching machine body 2. After alignment, the processing tool on the punching machine body 2 can process the material, thereby transferring the material from the conveyor belt 6 to the corresponding processing position on the punching machine body 2. Thus, after automatic feeding, the material is clamped and can be processed by the punching machine body 2, reducing manual intervention and avoiding operational errors or instability caused by manual operation.

[0029] Example 2: Based on Example 1, a feeding mechanism is also disclosed, the specific structure of which is as follows:

[0030] The feeding mechanism includes an inclined baffle 15, which is fixedly connected to the inside of the base 1. An inclined plate 18 is also provided inside the base 1. A collection box 16 is provided below the inclined baffle 15. The inclined plate 18 and the inclined baffle 15 are staggered vertically. The sliding clamping block 14 is L-shaped. Two connecting rods 12 are located on the side where the two eccentric wheels 11 are close to each other.

[0031] After processing, the sliding clamping block 14 moves in the opposite direction, releasing the material. At this point, the processed material loses the grip of the sliding clamping block 14 and falls onto the conveyor belt 6 under gravity. An inclined plate 18 is installed on one side of the conveyor belt 6. Therefore, under the conveyor belt 6, the processed material first falls onto the inclined plate 18. Due to the inclination angle of the inclined plate 18, the material slides down along it, and is further guided by the inclined baffle 15 before finally falling into the collection box 16 below, completing the material unloading and collection. The inclined plate 18 and the inclined baffle 15 are staggered vertically. This arrangement allows the material to undergo multiple buffering and guiding processes during its descent, preventing direct impact and reducing material damage. At the same time, it can guide the material to the collection box 16 more accurately; the sliding clamping block 14 is L-shaped, which can better contact and clamp the material, increase the contact area with the material, improve the stability of clamping, and ensure that the material will not fall during the transfer process; the two connecting rods 12 are set on the side of the two eccentric wheels 11 that are close to each other. When the two eccentric wheels 11 rotate synchronously, the connecting rods 12 on the two eccentric wheels 11 will also rotate synchronously. The direction of movement of one connecting rod 12 is clockwise, and the direction of movement of the other connecting rod 12 is counterclockwise. This enables the two eccentric wheels 11 to drive the connecting rods 12 to clamp the material in opposite directions, ensuring that the clamping mechanism can efficiently and stably complete the clamping and releasing action of the material, and realize the function of automatic loading and unloading.
