Description

A mechanical gripping device for industrial robots Technical Field

[0001] This utility model belongs to the field of mechanical gripping technology, specifically relating to a mechanical gripping device for industrial robots. Background Technology

[0002] In modern industrial production, mechanical gripping devices are an indispensable part of automated production lines. They are widely used in material handling, assembly, packaging and other processes to improve production efficiency and reduce labor costs. Existing mechanical gripping devices are usually designed for a single function. For example, some devices are specifically designed to clamp workpieces of fixed shape and size, while others may be limited to performing specific clamping actions, such as clamping in the vertical or horizontal direction.

[0003] For example, traditional vertical clamping devices typically consist of a pair of parallel clamping plates. A drive mechanism moves the clamping plates closer to or further apart to clamp and release the workpiece. However, such devices often fall short when dealing with irregularly shaped workpieces or those requiring horizontal clamping. On the other hand, devices specifically designed for horizontal clamping may not provide sufficient vertical clamping force, limiting their application range.

[0004] Therefore, there is an urgent need in the market for a mechanical gripping device that is simple in structure, low in cost, and can flexibly adapt to different gripping needs. Summary of the Invention

[0005] The purpose of this invention is to provide a mechanical gripping device for industrial robots, which can simultaneously achieve vertical gripping functions similar to fingers or hooks and horizontal gripping functions in a single device, greatly improving the applicability and working efficiency of the device and meeting the needs of modern industrial production for multifunctional gripping devices.

[0007] A mechanical gripping device for an industrial robot includes a device body, push rod motors rotatably connected to both sides of the device body near the bottom, and clamping frames rotatably connected to both sides of the device body near the top, with the output end of the clamping frame on the same side rotatably connected to the push rod motor.

[0008] A lateral displacement clamping mechanism is also installed at the bottom of the device body.

[0009] The lateral displacement clamping mechanism includes two sliding plates that are laterally slidably connected to the bottom of the device body. A reset member is provided between the two sliding plates. A sliding clamp is slidably connected to the inside of each sliding plate, and the sliding clamp is slidably connected to the device body.

[0010] The sliding clamp has racks evenly arranged on its side. A gear is rotatably connected inside the sliding plate, and the rack meshes with the gear. A drive motor is also installed inside the sliding plate. A connecting structure is installed at the output end of the drive motor, and the connecting structure is connected to the gear.

[0011] The connection structure includes a worm gear fixed to the output end of the drive motor. A worm wheel is meshed with the side of the worm gear near the gear. The worm wheel is fixedly connected to the center position of the gear and is rotatably connected to the sliding plate.

[0012] The reset component is a spring, and the two ends of the spring are respectively connected to two sliding plates.

[0013] A limit rod is fixed inside the main body of the device and inside the spring, and the limit rod is slidably connected to two sliding plates.

[0014] The bottom of the push rod motor is provided with multiple limiting grooves, and the sliding clamp is provided with a limiting strip corresponding to the limiting groove on the side near the limiting groove.

[0015] The technical effects achieved by this utility model are as follows:

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] As shown in Figures 1-5, a mechanical gripping device for an industrial robot includes a device body 1, push rod motors 2 are rotatably connected to both sides of the device body 1 near the bottom, and clamping frames 3 are rotatably connected to both sides of the device body 1 near the top, with the output end of the clamping frame 3 on the same side being rotatably connected to the push rod motor 2.

[0026] When using this device to clamp a workpiece, the two clamping frames 3 can be activated, and the stroke rods of the clamping frames 3 can be extended and rotated at the top of the push rod motor 2. Then, through the lever principle, the lower part of the push rod motor 2 moves inward. By moving the lower parts of the two push rod motors 2 toward each other, the workpiece can be clamped.

[0027] A lateral displacement clamping mechanism is also installed at the bottom of the device body 1.

[0028] Referring to Figures 2-4, the lateral displacement clamping mechanism includes two sliding plates 4 laterally slidably connected to the bottom of the device body 1. A reset element is provided between the two sliding plates 4. Referring to Figure 5, the reset element is a spring 11, and both ends of the spring 11 are respectively connected to the two sliding plates 4. After the two sliding plates 4 move towards each other, the push rod motor 2 resets, and the two sliding plates 4 are also reset by the spring 11. The lower part of the device body 1 is provided with a sliding groove for the sliding plates 4, so that both sliding plates 4 can move towards the edge and fit against the side of the sliding groove, thereby... The sliding plate 4 is reset. Furthermore, a limiting rod 12 is fixed inside the device body 1 and inside the spring 11. The limiting rod 12 is slidably connected to the two sliding plates 4. By setting the limiting rod 12, the spring 11 can only be compressed when it is pressed, and will not be tilted, thereby avoiding damage to the spring 11. The sliding plate 4 is slidably connected to the sliding clamp 5 inside, and the sliding clamp 5 is slidably connected to the device body 1 inside. The device body 1 is provided with a groove, so that the sliding clamp 5 can enter the groove when not in use.

[0029] The sliding clamp 5 has racks 6 evenly arranged on its side. The top of the sliding clamp 5 has a horizontal piece that can engage with the sliding plate 4, so that the sliding clamp 5 can not move further after moving down to a certain position, thus preventing the sliding clamp 5 from falling off. The sliding plate 4 is rotatably connected to a gear 7, and the racks 6 are meshed with the gears 7. The sliding plate 4 is also equipped with a drive motor 10. The output end of the drive motor 10 is equipped with a connecting structure, which is connected to the gear 7.

[0030] When the drive motor 10 is driven, it can drive the connecting structure, and through the connecting structure, it can drive the gear 7 to rotate. Through the meshing connection between the gear 7 and the rack 6, the gear 7 can drive the rack 6 and the sliding clamp 5 to move downward when it rotates.

[0031] After the sliding clamp 5 moves down to a certain extent, the clamping frame 3 can be activated, causing the lower parts of the two push rod motors 2 to move toward each other, thereby pushing the sliding clamp 5. This causes the sliding clamp 5 to drive the rack 6 to slide under the device body 1. With this setting, the clamping action of the two push rod motors 2 moving inward and hooking upward can be changed to the clamping action of the two sliding clamps 5 moving laterally, thus adapting to different clamping needs and different clamping workpieces.

[0032] The bottom of the push rod motor 2 is provided with multiple limiting grooves 13. The sliding clamp 5 is provided with a limiting strip 14 corresponding to the limiting groove 13 on the side near the limiting groove 13. When the two limiting grooves 13 move toward their respective sliding clamps 5, they can move through the limiting grooves 13 into the limiting strip 14, so that the limiting strip 14 guides the limiting groove 13.

[0033] Referring to Figure 4, the connection structure includes a worm 9 fixed to the output end of the drive motor 10. A worm wheel 8 is meshed with the side of the worm 9 near the gear 7. The worm wheel 8 is fixedly connected to the center of the gear 7, and the worm wheel 8 is rotatably connected to the sliding plate 4.

[0034] When the drive motor 10 is driven, it can drive the worm 9 to rotate, and through the meshing connection between the worm 9 and the worm wheel 8, the worm 9 drives the worm wheel 8 to rotate, which in turn drives the gear 7 to rotate.

[0035] By configuring the worm 9 and worm wheel 8, the worm 9 can only drive the worm wheel 8 to rotate, while the worm wheel 8 cannot drive the worm 9 to rotate. This allows the worm wheel 8 to overcome the gravity of the sliding clamp 5 falling down and prevent the sliding clamp 5 from shifting downwards.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
