Description

Technical Field

[0001] The utility model relates to the technical field of mechanical grippers, in particular to an electric hybrid driven clamping mechanism. Background Art

[0002] In the field of industrial automation, gripping mechanisms are essential equipment for material handling and processing, and are widely used in various links of production lines. Traditional gripping mechanisms typically use the relative movement of two jaws to grip and transport materials. Although this design is simple and intuitive, it has the following shortcomings in practical applications:

[0003] The material is held between two grippers during transportation, and the material is prone to displacement and slippage during the movement, and there is even a risk of falling off.

[0004] If a large-sized thin plate material is encountered, the center of the material will fall, and the material will change from a flat state to a curved state, which can easily fall off the clamping jaws and cause the clamped material to deform. Utility Model Content

[0005] The purpose of the utility model is to provide an electric hybrid driven clamping mechanism, which first clamps and holds the material through the clamping claws at both ends, and then presses the material through the pressing claws at both ends, thereby improving the stability of the material during the moving and transportation process.

[0006] The utility model adopts the following technical solution: an electric hybrid driven clamping mechanism, comprising:

[0007] A mounting plate, a pair of mutually parallel slide rails being fixed to the lower side of the mounting plate;

[0008] A pair of clamping jaws are slidably mounted on the slide rail and are disposed at both ends of the slide rail; the clamping jaws have a lifting portion for lifting materials;

[0009] A horizontal driving mechanism, mounted on the mounting plate, for driving the two clamping jaws to move along the slide rail;

[0010] A pair of pressing jaws are slidably mounted on the two clamping jaws in a one-to-one correspondence; the pressing jaws have a pressing portion opposite to the lifting portion of the clamping jaws;

[0011] A pair of lifting mechanisms are mounted on the two clamping jaws in a one-to-one correspondence and fixedly connected to the corresponding pressing jaws, and are used to drive the pressing portion of the pressing jaws to move closer to or away from the lifting portion of the clamping jaws.

[0012] It is further provided with a through hole for connecting with the robotic arm.

[0013] The clamping jaw includes a vertical plate, the upper end of which is fixedly connected to a sliding seat slidably mounted on a slide rail; the lower end of the vertical plate has a plurality of lifting portions extending toward the inner side of the clamping jaw, and a clamping jaw pad is fixed on the upper side of the lifting portion.

[0014] The pressure claw includes a pressure plate fixing seat arranged on the inner side of the vertical plate, a plurality of the pressing parts are fixed on the lower side of the pressure plate fixing seat, and a pressure claw pad is fixed on the lower side of the pressing part; the pressure claw pad is opposite to the clamping claw pad up and down.

[0015] The lifting mechanism includes a lifting cylinder fixed on the outside of the vertical plate; the output end of the lifting cylinder is vertically downward, and a horizontal plate is fixed to the output end of the lifting cylinder; a through groove for the horizontal plate to pass through is opened on the vertical plate, and the inner end of the horizontal plate is fixedly connected to the pressure plate fixing seat.

[0016] The lifting cylinder is a double-axis cylinder.

[0017] The slide rail includes two connecting blocks separately fixed at both ends of the mounting plate, an optical axis seat is fixedly mounted on the connecting block, a linear optical axis is mounted between the two optical axis seats, and a linear slider is slidably mounted on the linear optical axis;

[0018] The sliding seat is fixed on the linear slide.

[0019] The horizontal driving mechanism comprises:

[0020] Gear, rotatably mounted at the center of the lower side of the mounting plate;

[0021] A motor reducer is fixed on the upper surface of the mounting plate; the output shaft of the motor reducer passes through the mounting plate and is fixedly connected to the gear;

[0022] A pair of racks are disposed on both sides of the gear and are respectively meshed with the gears; the two racks are parallel to the linear optical axis, and the two racks are fixedly connected to the two sliding seats in a one-to-one correspondence;

[0023] Two sets of idler wheels are respectively arranged on the sides of the two racks and are used for guiding the racks.

[0024] The beneficial effects of the present invention are:

[0025] A pressure claw is added to the clamping claw, which is driven by the lifting mechanism to press the material vertically. The pressure claw and the clamping claw work together to form a clamping force in both horizontal and vertical directions, effectively preventing the material from sliding and falling off during movement, and improving the stability of the material during transportation.

[0026] The electric hybrid drive gripping mechanism can adapt to materials of different shapes and sizes by adjusting the position and force of the gripping jaws and the pressing jaws. Especially for large-sized thin materials, the pressing action of the pressing jaws effectively prevents the center of the material from falling and deforming. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example 1:

[0040] like Figures 1 to 4 As shown, the present invention provides an electric hybrid drive gripping mechanism. A mounting plate 1 is provided with a through-hole for connection to a robotic arm. A pair of parallel slide rails 2 are fixed to the underside of the mounting plate 1. A gripping jaw 3 is slidably mounted on each end of the slide rails 2. A horizontal drive mechanism 4 is fixed to the mounting plate 1 and controls the movement of the two gripping jaws 3 toward or away from each other along the slide rails 2.

[0041] The clamping jaws 3 comprise a vertical plate 31, the upper end of which is fixed to the lower end of a sliding base 33, which is slidably mounted on the slide rail 2. The lower end of the vertical plate 31 has multiple lifting portions extending inward toward the inside of the clamping jaws 3. These lifting portions are used to lift materials. A clamping jaw pad 32 is fixed to the upper side of these lifting portions. When the horizontal drive mechanism 4 drives the two clamping jaws 3 to grasp materials, the clamping jaw pad 32 abuts against the lower side of the material.

[0042] Each clamping jaw 3 is provided with a pressing jaw 5 and a lifting mechanism 6 for driving the pressing jaw 5;

[0043] The clamping jaw 5 includes a clamping plate fixing base 51 disposed inside the vertical plate 31. The clamping plate fixing base 51 is located above the lifting portion of the clamping jaw 3. Multiple pressing portions are fixed to the underside of the clamping plate fixing base 51. Underneath these pressing portions are clamping jaw pads 52, which are positioned one above the other and face the clamping jaw pads 32.

[0044] The lifting mechanism 6 is used to control the up and down movement of the pressure claw 5 so that the pressing part of the pressure claw 5 is close to or away from the lifting part of the clamping jaw 3. The lifting mechanism 6 includes a lifting cylinder 61 fixed to the outside of the vertical plate 31. The lifting cylinder 61 is a double-axis cylinder. The output end of the lifting cylinder 61 is arranged vertically, and a U-shaped horizontal plate 62 is fixed to the output end of the lifting cylinder 61. Two vertical through slots 311 for the horizontal plate 62 to pass through are provided on the vertical plate 31. The horizontal plate 62 passes through the through slots 311, and the inner end of the horizontal plate 62 is fixedly connected to the pressure plate fixing seat 51.

[0045] Example 2:

[0046] Based on the above embodiment 1, combined with Figures 1 to 4As shown, the slide rail 2 includes two connecting blocks 21 fixed at either end of the mounting plate 1. An optical axis seat 22 is fixed to the lower end of the connecting blocks 21. A linear optical axis 23 is mounted between the two optical axis seats 22, and two linear sliders 24 are slidably mounted on the linear optical axis 23. A sliding seat 33 at the upper end of each clamping jaw 3 is fixed to the two linear sliders 24 on the same side, allowing the two clamping jaws 3 to move linearly along the two linear optical axes 23.

[0047] The horizontal drive mechanism 4 includes a gear 42 rotatably mounted at the center of the lower side of the mounting plate 1, and a motor reducer 41 fixed at the center of the upper surface of the mounting plate 1. The output shaft of the motor reducer 41 passes through the mounting plate 1 and is fixedly connected to the gear 42, driving the gear 42 in forward and reverse rotation. A rack 43 is fixedly connected to each sliding seat 33. The two racks 43 are positioned on either side of the gear 42 and mesh with each other. The racks 43 are parallel to the linear optical axis 23. Also mounted on the lower side of the mounting plate 1 are two sets of idler gears 44. These two sets of idler gears 44 are positioned on the sides of the two racks 43 and are in rolling contact with the sides of the racks 43, guiding the racks 43.

[0048] Working process:

[0049] The motor reducer 41 drives the gear 42 to rotate, and the gear 42 drives the racks 43 on both sides, and the racks 43 on both sides drive the clamping jaws 3 on both sides to clamp the material, and the clamping jaw pads 32 of the clamping jaws 3 support the two ends of the material; the lifting cylinders 61 on both sides extend, driving the pressing jaws 5 to move downward until the pressing jaw pads 52 are pressed on the two ends of the material, and finally the whole body moves to the predetermined position.

[0050] This new design, by adding a pressure claw and lifting mechanism to the traditional gripping mechanism, achieves both horizontal and vertical gripping of materials, effectively solving the problems of material displacement, slippage, and falling during movement. This improves the gripping mechanism's applicability, reliability, and stability. Furthermore, the hybrid electric drive and automated operation simplify operation and maintenance, reducing operational difficulty and maintenance costs.

[0051] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
