Description
Technical Field
[0001] The utility model relates to the field of clamping devices, in particular to a rapid workpiece clamping device for agricultural machinery manufacturing. Background Technique
[0002] Agricultural machinery refers to various machines used in the processes of crop planting and animal husbandry, as well as the primary processing and treatment of agricultural and livestock products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilizing machinery, etc. During the production and processing process, it often needs to be welded or clamped by various devices to ensure that the produced equipment has high precision.
[0003] Most workpiece clamping devices are composed of components such as a placement table and a fixed fixture. After the worker places the mechanical workpiece to be processed on the tabletop, the hydraulic fixture can be started to fix the workpiece, ensuring that the position of the workpiece will not shift when the worker drills or welds the workpiece subsequently, and ensuring the processing effect.
[0004] However, most of the existing workpiece clamping devices use hydraulic pressure or cylinders to provide power for the fixture. In this way, the worker needs to manually control the start or stop of the fixing device when processing each mechanical workpiece, reducing the overall work efficiency, and the repeated fixing and installation will increase the work intensity of the worker. Content of the Utility Model
[0005] Based on this, the purpose of the utility model is to provide a rapid workpiece clamping device for agricultural machinery manufacturing to solve the technical problems mentioned in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A rapid workpiece clamping device for agricultural machinery manufacturing, including a machine body. A connecting rod is movably installed inside the machine body, and a pressing plate is fixedly installed at one end of the connecting rod. A first spring connected to the machine body and the pressing plate is sleeved outside the connecting rod. A first rack is fixedly installed at one end of the pressing plate, and a threaded rod is movably installed inside the machine body. A first gear meshing with the first rack is fixedly installed at one end of the threaded rod, and a first gear is movably installed at one end of the threaded rod. A moving block is fixedly installed at one end of the first gear, and a second rack is fixedly installed at one end of the moving block. A rotating rod is movably installed inside the machine body, and a second gear meshing with the second rack is fixedly installed at one end of the rotating rod. A clamping assembly is movably installed inside the machine body.
[0007] By adopting the above technical solution, by providing components such as a first rack, a threaded rod, a first gear, a second rack, a third gear and a third rack, when a worker uses this equipment, only need to place the mechanical workpiece to be clamped and fixed on the end face of the machine body, and the self-weight of the workpiece drives the movable clamping plates on both sides to displace a certain distance, so as to automatically fix and limit the mechanical workpiece. Compared with the traditional method of manually starting the hydraulic device by the worker to fix the workpiece, this equipment can greatly reduce the time required for clamping and fixing, effectively reduce the working intensity of the worker, and greatly improve the overall working efficiency.
[0008] The present utility model is further configured such that the clamping assembly includes a third gear, a movable clamping plate, a connecting plate, a third rack, a slider, a chute and a movable groove. The movable clamping plate is movably installed inside the machine body, and one end of the movable clamping plate is fixedly installed with a connecting plate, and one end of the connecting plate is fixedly installed with a slider.
[0009] By adopting the above technical solution, the movably installed movable clamping plate enables it to move a certain distance inside the machine body. The connecting plate is fixedly connected to the movable clamping plate, so that when the connecting plate moves, it will drive the movable clamping plate to move together, thus providing conditions for driving the movable clamping plate subsequently. The fixedly installed slider enables the connecting plate to be restricted by the slider during the moving process.
[0010] The present utility model is further configured such that a chute for the slider to move is provided inside the machine body, and a movable groove for the connecting plate to move is provided at one end of the machine body.
[0011] By adopting the above technical solution, the slider cooperates with the chute to restrict the moving direction of the connecting plate and prevent its position from shifting during the moving process. The setting of the movable groove enables the connecting plate to move inside the machine body and provides a certain restriction to the connecting plate to ensure its moving direction.
[0012] The present utility model is further configured such that a third gear is fixedly installed in the middle of the rotating rod, a third rack meshing with the third gear is fixedly installed at one end of the connecting plate, and a first limiting rod for restricting the moving block is fixedly installed inside the machine body.
[0013] By adopting the above technical solution, the fixedly installed third gear rotates together with the rotating rod. When the second gear is driven to rotate by the second rack, the third gear drives the third rack, so as to drive the two movable clamping plates to move in opposite directions to fix and limit the workpiece. The setting of the first limiting rod can ensure that the moving block does not rotate together with the threaded rod and ensure that it can normally drive the second gear.
[0014] The utility model is further configured that an L-shaped plate is fixedly installed at one end of the fixing plate, and a second limiting rod is movably installed inside the L-shaped plate, and a limiting groove matching with the second limiting rod is opened inside the pressing plate.
[0015] By adopting the above technical solution, the fixed plate provides fixing conditions for the L-shaped plate, and the movably installed second limit rod allows it to move inside the L-shaped plate. The second limit rod cooperates with the limit groove, so that after the second limit rod enters the limit groove, the pressure plate can be fixed and restricted, ensuring that the position of the movable clamping plate will not change during the process of fixing and clamping the mechanical workpiece, thereby ensuring the fixing effect.
[0016] The utility model is further configured such that a limiting plate is fixedly mounted on one end of the second limiting rod, and the diameter of the limiting plate is larger than the diameter of the second limiting rod, and a second spring is sleeved on the outside of the second limiting rod.
[0017] By adopting the above technical solution, the diameter of the limiting plate is larger than the second limiting rod, so that the limiting plate can provide limitation to the second limiting rod, preventing the second limiting rod from being separated from the inside of the L-shaped plate due to the elastic force of the second spring. The second spring will continue to provide elastic force to the second limiting rod, so that when it is squeezed by the pressure plate and moves backward, when it moves to the limiting groove, the second limiting rod can normally enter the inside thereof, thereby fixing and limiting the pressure plate.
[0018] In summary, the utility model mainly has the following beneficial effects:
[0019] 1. The utility model is provided with components such as a first rack, a threaded rod, a first gear, a second rack, a third gear and a third rack, so that when using the equipment, workers only need to place the mechanical workpiece to be clamped and fixed on the end face of the machine body, and the movable clamping plates on both sides thereof are driven to move a certain distance by the weight of the workpiece itself, so as to automatically fix and restrict the mechanical workpiece. Compared with the traditional workers manually starting the hydraulic device to fix the workpiece, the equipment can greatly reduce the time required for clamping and fixing, and at the same time effectively reduce the work intensity of the workers, and greatly improve their overall work efficiency.
[0020] 2. The utility model is provided with a second limit rod, a limit groove, a second spring, a first spring and a pressure plate, so that after the worker places the clamped workpiece, when the pressure plate moves downward, the second limit rod enters the inside of the limit groove to fix and limit the pressure plate, effectively ensuring that the position of the movable clamp will not move during the processing of the workpiece, thereby affecting the processing of the workpiece. At the same time, after the second limit rod is pulled to take out the processed workpiece, the first spring applies elastic force to it to help reset the equipment and improve work efficiency.

Specific embodiments
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0027] Next, the embodiments of the present utility model will be described according to its overall structure.
[0028] A workpiece rapid clamping device for agricultural machinery manufacturing, as Figures 1-4As shown in the figure, it includes a machine body 1. A connecting rod 3 is movably installed inside the machine body 1. One end of the connecting rod 3 is fixedly installed with a pressing plate 4. A first spring 5 connected to the machine body 1 and the pressing plate 4 is sleeved outside the connecting rod 3. One end of the pressing plate 4 is fixedly installed with a first rack 6. A threaded rod 7 is movably installed inside the machine body 1. One end of the threaded rod 7 is fixedly installed with a first gear 8 meshing with the first rack 6. One end of the threaded rod 7 is movably installed with the first gear 8. One end of the first gear 8 is fixedly installed with a moving block 9. One end of the moving block 9 is fixedly installed with a second rack 11. A rotating rod 14 is movably installed inside the machine body 1. One end of the rotating rod 14 is fixedly installed with a second gear 12 meshing with the second rack 11. A clamping assembly is movably installed inside the machine body 1. When a worker uses this equipment, only need to place the mechanical workpiece to be processed on the end face of the machine body 1. The weight of the workpiece itself causes the position of the pressing plate 4 to move downward, which will drive the threaded rod 7 to rotate, causing the moving block 9 on one side of it to displace. The movable clamping plate 15 inside the machine body 1 is affected by the rotating third gear 13, and thus moves in an opposite direction, so as to fix and limit the mechanical workpiece to be processed through the movable clamping plate 15, ensuring that its position will not shift during the processing process.
[0029] Please refer to Figure 2 - Figure 3 The clamping assembly includes a third gear 13, a movable clamping plate 15, a connecting plate 16, a third rack 17, a slider 18, a chute 19 and a movable slot 25. A movable clamping plate 15 is movably installed inside the machine body 1. One end of the movable clamping plate 15 is fixedly installed with a connecting plate 16. One end of the connecting plate 16 is fixedly installed with a slider 18. The movably installed movable clamping plate 15 enables it to move a certain distance inside the machine body 1. The connecting plate 16 is fixedly connected to the movable clamping plate 15, so that when the connecting plate 16 moves, it will drive the movable clamping plate 15 to move together, thus providing conditions for driving the movable clamping plate 15 subsequently. The fixedly installed slider 18 makes the connecting plate 16 need to be restricted by the slider 18 during the moving process.
[0030] Please refer to Figure 3 A chute 19 for the slider 18 to move is opened inside the machine body 1. An activity slot 25 for the connecting plate 16 to move is opened at one end of the machine body 1. The slider 18 cooperates with the chute 19, enabling it to restrict the moving direction of the connecting plate 16 and prevent its position from shifting during the moving process. The setting of the activity slot 25 enables the connecting plate 16 to move inside the machine body 1 and at the same time provides a certain restriction on the connecting plate 16 to ensure its moving direction.
[0031] Please refer to Figure 2 - Figure 3A third gear 13 is fixedly installed in the middle of the rotating rod 14, and a third rack 17 meshing with the third gear 13 is fixedly installed at one end of the connecting plate 16. A first limiting rod 10 for limiting the moving block 9 is fixedly installed inside the body 1. The fixedly installed third gear 13 allows it to rotate together with the rotating rod 14, so that when the second gear 12 is driven to rotate by the second rack 11, the third rack 17 will be transmitted through the third gear 13, thereby driving the two sets of movable splints 15 to move in opposite directions to fix and limit the workpiece. The setting of the first limiting rod 10 can ensure that the moving block 9 will not rotate together with the threaded rod 7, thereby ensuring that it can provide drive for the second gear 12 normally.
[0032] See also Figure 1 - Figure 4 An L-shaped plate 20 is fixedly installed at one end of the fixed plate 2, and a second limiting rod 21 is movably installed inside the L-shaped plate 20. A limiting groove 24 that cooperates with the second limiting rod 21 is opened inside the pressure plate 4. The fixed plate 2 provides fixing conditions for the L-shaped plate 20. The movably installed second limiting rod 21 allows it to move inside the L-shaped plate 20. The second limiting rod 21 cooperates with the limiting groove 24, so that after the second limiting rod 21 enters the limiting groove 24, the pressure plate 4 can be fixed and restricted, ensuring that the position of the movable clamping plate 15 will not change during the process of fixing and clamping the mechanical workpiece, thereby ensuring the fixing effect.
[0033] See also Figure 1 - Figure 4 A limiting plate 23 is fixedly installed at one end of the second limiting rod 21, and the diameter of the limiting plate 23 is larger than the diameter of the second limiting rod 21. A second spring 22 is sleeved on the outside of the second limiting rod 21, and the diameter of the limiting plate 23 is larger than the second limiting rod 21, so that the limiting plate 23 can provide limitation to the second limiting rod 21 to prevent the second limiting rod 21 from escaping from the inside of the L-shaped plate 20 due to the elastic force of the second spring 22. The second spring 22 will continue to provide elastic force to the second limiting rod 21, so that when it is squeezed by the pressure plate 4 and moves backward, when it moves to the limiting groove 24, the second limiting rod 21 can normally enter its interior to provide fixation and limitation to the pressure plate 4.
[0034] The working principle of the present utility model is as follows: When a worker uses this equipment, only need to place the mechanical workpiece to be processed on the end face of the machine body 1, and the fixing plate 2 can quickly help to position it. The weight of the workpiece itself causes the position of the pressing plate 4 to move downward, which will drive the threaded rod 7 to rotate, so that the moving block 9 on one side thereof displaces, driving the rotating rod 14 to rotate. The movable clamping plate 15 inside the machine body 1 is affected by the rotating third gear 13, and thus moves towards each other, so as to fix and limit the mechanical workpiece to be processed through the movable clamping plate 15, ensuring that its position will not shift during the processing. At the same time, when the position of the pressing plate 4 moves downward, it will squeeze the second limiting rod 21. When it moves to the limiting groove 24, the second spring 22 applies an elastic reset force to the second limiting rod 21, so that the second limiting rod 21 enters into the pressing plate 4 to complete the fixing and limiting of the pressing plate 4, effectively preventing the position of the pressing plate 4 from changing and affecting the fixing effect of the movable clamping plate 15.
[0035] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations without creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
