Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically to a magazine-type feeding mechanism. Background Technology

[0002] A bench vise, also known as a bench clamp, is a general-purpose clamping tool used to hold workpieces. A bench vise consists of a movable jaw and a fixed jaw. The movable jaw has movable jaws mounted on it with screws, and the fixed jaw has fixed jaws mounted on it with screws. By moving the movable jaw towards the fixed jaw, the movable jaw engages with the fixed jaw to clamp the workpiece. To improve the hardness and wear resistance of the movable and fixed jaws, they undergo high-frequency quenching. In existing technology, the jaws are typically placed manually one by one on a conveyor belt, transported to their destination, and then each workpiece is sequentially induction hardened. Because this requires continuous manual placement of the jaws on the conveyor belt, it is time-consuming and labor-intensive. Therefore, improving the loading efficiency of the jaws and saving manpower is a problem that needs to be solved. Utility Model Content

[0003] This utility model addresses the existing technical problems by providing a magazine-type feeding mechanism.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A magazine-type feeding mechanism includes a frame, a feeding conveyor belt, a pusher plate, and a drive motor. The feeding conveyor belt is installed on the frame via rollers. The feeding conveyor belt is provided with a feeding area. A bottom plate is provided on one side of the feeding area, and a limiting strip is provided on the other side. Multiple vertically arranged material boxes are installed on the bottom plate. Each material box is used to stack multiple workpieces. The bottom of each material box is provided with a discharge port. A receiving space is provided between the bottom of the material box and the bottom plate. The height of the receiving space is greater than or equal to the thickness of a single workpiece. The pusher plate is slidably disposed in the receiving space. The thickness of the pusher plate is less than or equal to the thickness of a single workpiece. The output end of the drive motor is connected to the pusher plate and drives the pusher plate to transport the workpiece at the discharge port to the feeding area.

[0005] The beneficial effects of this utility model are as follows: by setting up a material box for stacking workpieces, the workpieces in the material box automatically fall onto the base plate under the action of gravity. The push plate, under the action of the drive motor, transports the workpieces to the loading area, and then transports them to the target position through the loading conveyor belt. The loading process does not require manual operation, which improves loading efficiency and saves labor costs. By setting up multiple material boxes, the number of loading times is further reduced, and loading efficiency is improved.

[0006] Based on the above technical solution, the present invention can further improve the above technical solution as follows:

[0007] Furthermore, it also includes an elastic pressure plate, which is disposed on the side wall at the lower end of the material box. The elastic pressure plate is located on the side of the material box near the feeding area. The bottom plate has a guiding slope at its end, which is close to the feeding area.

[0008] The beneficial effects of adopting the above-mentioned further technical solution are that by setting the guide slope, the workpiece can slide down along the guide slope onto the feeding conveyor belt, reducing the probability of the workpiece flipping or rolling off. By setting the elastic pressure plate, the workpiece is pressed to prevent it from flipping when it is transported from the bottom plate to the feeding area of ​​the feeding conveyor belt, ensuring that the front of the workpiece is always facing upwards, so as to facilitate the normal heat treatment of the workpiece in the future.

[0009] Furthermore, the elastic pressure plate includes an integral fixing section and a pressing section. The fixing section is installed on the material box, and the pressing section is inclined downward along the conveying direction of the workpiece.

[0010] The beneficial effect of adopting the above-mentioned further technical solution is that it can ensure the normal installation of the elastic pressure plate and the clamping effect on the workpiece.

[0011] Furthermore, the end of the clamping section is provided with an upwardly bent flange, the clamping section and the flange are smoothly transitioned, and the flange is located at the end away from the fixing section.

[0012] The beneficial effect of adopting the above-mentioned further technical solution is that it can not only ensure the clamping effect on the workpiece and prevent it from flipping, but also avoid the situation of jamming between the elastic pressure plate and the workpiece, thus ensuring the normal conveying of the workpiece.

[0013] Furthermore, the discharge port includes a current discharge port and a discharge port to be discharged, and the starting position of the push plate is located below the discharge port to be discharged, and at least 1 / 2 of the width of the discharge port to be discharged is blocked.

[0014] The beneficial effect of adopting the above-mentioned further technical solution is that it ensures that only the current discharge port discharges material, thereby realizing that only one workpiece is transported to the loading area at a time, ensuring that each workpiece can be heat-treated sequentially thereafter.

[0015] Furthermore, one end of the base plate is mounted on the frame via a support column, and the other end is mounted on the frame via a first bracket and a second bracket.

[0016] The beneficial effect of adopting the above-mentioned further technical solution is to ensure the firmness and stability of the base plate installation and to ensure that the push plate can move normally on the base plate.

[0017] Furthermore, the output end of the drive motor is connected to a screw, the screw is threadedly connected to the slider, the slider is slidably mounted on the frame, and the push plate is connected to the slider.

[0018] The beneficial effect of adopting the above-mentioned further technical solution is that when the drive motor is working, it drives the screw to rotate in both directions, and the screw drives the slider to move back and forth, thereby driving the push plate to move back and forth along the base plate, and realizing the automatic pushing of the workpiece to the loading area.

[0019] Furthermore, the drive motor and the slider are located below the base plate, and the base plate is provided with a through hole, through which the push plate passes and connects to the slider.

[0020] The advantages of adopting the above-mentioned further technical solution are that the overall structure is compact, the space occupied is reduced, and it is convenient to observe the movement of the slider and facilitate maintenance.

[0021] Furthermore, a gap is provided between the base plate and the limiting strip and the feeding conveyor belt.

[0022] The beneficial effect of adopting the above-mentioned further technical solution is that by setting a gap between the base plate and the feeding conveyor belt, the feeding conveyor belt can be ensured to move smoothly and steadily, and the wear of the feeding conveyor belt can be reduced, thereby increasing the service life of the feeding conveyor belt.

[0023] Furthermore, a U-shaped groove is provided on the side wall of the material box.

[0024] The beneficial effect of adopting the above-mentioned further technical solution is that it makes it easier to observe the number of workpieces in the material box so that workpieces can be added in a timely manner. Attached Figure Description

[0031] In the description of this invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," and "right," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0033] like Figures 1 to 5As shown, this utility model discloses a magazine-type feeding mechanism, including a frame 1, a feeding conveyor belt 2, a push plate 7, and a drive motor 8. The feeding conveyor belt 2 is mounted on the frame 1 via a roller shaft 17. Only a portion of the structure of the feeding conveyor belt 2 is shown in the figure. Under the action of the existing drive device, the feeding conveyor belt 2 rotates around the roller shaft 17 to continuously transport workpieces 5. The feeding conveyor belt 2 is provided with a feeding area 16. A base plate 9 is provided on one side of the feeding area 16, and a limiting strip 3 is provided on the other side of the feeding area 16. The limiting strip 3 is mounted on the frame 1 and extends along the conveying direction of the feeding conveyor belt 2. The limiting strip 3 limits the position of the workpiece 5 at the feeding area 16 to prevent the workpiece 5 from shifting. Furthermore, there are gaps between the bottom of the base plate 9 and the bottom of the limiting strip 3 and the feeding conveyor belt 2 to prevent the base plate 9 and the limiting strip 3 from contacting the feeding conveyor belt. 2. Friction occurs, reducing wear on the feeding conveyor belt 2. Multiple vertically arranged material boxes 4 are installed on the base plate 9. The number of material boxes 4 can be set according to the space and heat treatment speed of the workpiece 5. Each material box 4 is used to stack multiple workpieces 5. In this embodiment, the workpiece 5 is a movable jaw or a fixed jaw. A U-shaped groove is opened on the side wall of the material box 4 to facilitate observation of the number of workpieces 5 so as to add workpieces 5 in time. The bottom of the material box 4 is provided with a discharge port. Under the action of gravity, the workpiece 5 falls from the discharge port onto the base plate 9. There is a receiving space between the bottom of the material box 4 and the base plate 9. The height of the receiving space is greater than or equal to the thickness of a single workpiece 5 and less than the thickness of two workpieces 5. Specifically, the height of the receiving space is 2mm-3mm higher than the thickness of a single workpiece 5 to ensure that only one workpiece 5 falls smoothly into the receiving space at a time. The push plate 7 is slidably set within the accommodating space. The output end of the drive motor 8 is connected to the push plate 7 and drives the push plate 7 to transport the workpiece 5 at the discharge port to the loading area 16. The drive motor 8 is a servo motor. The thickness of the push plate 7 is less than or equal to the thickness of a single workpiece 5. Specifically, the thickness of the push plate 7 is 1mm-0.5mm smaller than the thickness of a single workpiece 5, so that only one workpiece 5 is transported at a time.

[0034] Furthermore, a second limiting strip 19 is installed on the frame 1. The second limiting strip 19 is set parallel to the first limiting strip 3. The space between the first limiting strip 3 and the second limiting strip 19 is formed for the workpiece 5 to pass through, ensuring that the workpiece 5 is transported smoothly and avoiding deviation.

[0035] The magazine-type feeding mechanism also includes an elastic pressure plate 6, which is a spring plate with a certain degree of elasticity. It can both ensure the clamping effect on the workpiece 5 and ensure that the push plate 7 can push the workpiece 5 to the feeding area 16. The elastic pressure plate 6 is set on the side wall of the lower end of the material box 4. The elastic pressure plate 6 is located on the side of the material box 4 near the feeding area 16. The end of the bottom plate 9 is provided with a guide slope 9-1. The guide slope 9-1 is close to the feeding area 16. The inclination angle of the guide slope 9-1 is 20°-22°, so that the width of the guide slope 9-1 is at least half the width of the workpiece 5. This ensures that the workpiece 5 is provided with sufficient support so that it can smoothly transition to the feeding area 16 of the feeding conveyor belt 2, reducing the probability of the workpiece 5 flipping. By setting the elastic pressure plate 6, the workpiece 5 is clamped to prevent it from flipping during the process of being transported from the bottom plate 9 to the feeding area 16, ensuring that the front of the workpiece 5 is always facing upwards, and ensuring that the workpiece 5 can be heat-treated normally in the future.

[0036] Specifically, the elastic pressure plate 6 includes an integral fixing section and a pressing section. The fixing section is installed on the side wall of the material box 4 by screws or bolts. The pressing section is inclined downward along the conveying direction of the workpiece 5. The end of the pressing section is provided with an upwardly bent flange. The pressing section and the flange are smoothly transitioned, and the flange is located at the end away from the fixing section. A certain gap is provided between the bottom end of the flange and the feeding conveyor belt 2. This gap is smaller than the thickness of the workpiece 5, which can achieve the effect of pressing the workpiece 5 and solve the problem of the workpiece 5 being affected by excessive pressing force.

[0037] In this embodiment, one end of the base plate 9 is detachably mounted on the frame 1 via two pillars 15, and the other end is mounted on the frame 1 via a first bracket 10 and a second bracket 11. The second bracket 11 is mounted on a U-shaped frame 18, which is mounted on the frame 1 and spans across the top of the feeding conveyor belt 2. This satisfies the requirement for stable installation of the base plate 9 and allows for appropriate adjustment of the position of the base plate 9 according to usage, i.e., adjusting the distance between the base plate 9 and the limiting strip 3, to ensure that the feeding area 16 has sufficient space to accommodate the workpiece 5 and to ensure the normal transport of the workpiece 5.

[0038] In this embodiment, specifically, the output end of the drive motor 8 is connected to a screw 13, which is threadedly connected to a slider 14. The slider 14 is slidably mounted on the frame 1, and the push plate 7 is connected to the slider 14. Further, the drive motor 8 and the slider 14 are located below the base plate 9, which has a through hole. The push plate 7 passes through the through hole and connects to the slider 14. Limiting plates 12 are provided on both sides of the push plate 7 and are mounted on the base plate 9. When the drive motor 8 operates, it drives the screw 13 to rotate in both directions, thereby causing the slider 14 and the push plate 7 to move reciprocally, achieving automatic feeding. The overall structure is compact, reducing space occupation, and facilitating observation of the slider 14's movement, thus simplifying maintenance.

[0039] In this embodiment, there are four material boxes 4, which are arranged from right to left as material box 1 4-1, material box 2 4-2, material box 3 4-3 and material box 4-4. The four material boxes 4 are arranged in an orderly manner. The discharge port includes the current discharge port and the discharge port to be discharged. The starting position of the push plate 7 is located below the discharge port to be discharged and blocks at least 1 / 2 of the width of the discharge port to be discharged, effectively blocking the workpiece 5 in the discharge port to be discharged, ensuring that only the workpiece 5 in the material box 4 corresponding to the current discharge port falls on the base plate 9 each time, ensuring the normal conveying of the workpiece 5.

[0040] The working process of this utility model is as follows:

[0041] First, the workpiece 5 is conveyed into material box 4-1. At this time, the discharge port at the lower end of material box 4-1 is the current discharge port, and the discharge port at the lower end of material box 4-2 is the discharge port to be discharged. The starting position of the push plate 7 is located at the discharge port to be discharged at the lower end of material box 4-2. Figure 5 At position a, the workpieces 5 in material boxes 2 (4-2) to 4 (4-4) are blocked, leaving only the workpieces 5 in material box 1 (4-1) falling onto the base plate 9 under gravity. The drive motor 8 drives the push plate 7 to move and push the workpieces 5 to the loading area 16 of the loading conveyor belt 2. Since the loading conveyor belt 2 rotates continuously around the roller shaft 17, it continuously transports the workpieces 5 in the loading area 16 to the next process. The push plate 7, driven by the drive motor 8, returns to the lower end of the discharge port. Figure 5 At position a, repeat the above action for the next conveying cycle until all workpieces 5 in material box 1 4-1 have been conveyed. The drive motor 8 is electrically connected to a counter, which counts the number of material boxes 4 and the number of workpieces 5 in each box 4. After the workpieces 5 in material box 1 4-1 have been conveyed, the workpieces 5 in material box 2 4-2 are conveyed. At this time, the discharge port at the lower end of material box 2 4-2 is the current discharge port, and the discharge port at the lower end of material box 3 4-3 is the waiting discharge port. The push plate 7 moves from its initial position to the waiting discharge port at the lower end of material box 3 4-3. Figure 5 At position b, repeat the above actions. When the workpiece 5 in material box 2 4-2 has been conveyed, the initial position of the push plate 7 moves to... Figure 5 At position c, the workpiece 5 continues to be conveyed in material box 3 4-3. When the workpiece 5 in material box 3 4-3 has been conveyed, the push plate 7 moves to its initial position. Figure 5 At position d, the workpieces 5 in the four-4 material box are conveyed until all workpieces 5 have been conveyed.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
