Description

Technical Field

[0001] The utility model relates to the technical field of industrial robots, in particular to a clamping claw assembly with a double limiting structure. Background Art

[0002] An industrial robot is a multi-joint manipulator or multi-degree-of-freedom machine device for the industrial field. It can perform work automatically and relies on its own power and control capabilities to achieve various functions. It can accept human commands or run according to pre-programmed programs. Modern industrial robots can also act according to the principles and guidelines formulated by artificial intelligence technology. In industrial production, industrial robots can replace humans to do certain monotonous, frequent and repetitive long-term operations, or operations in dangerous and harsh environments, such as stamping, pressure casting, heat treatment, welding, painting, and plastic product forming.

[0003] In processes such as mechanical processing and simple assembly, as well as in departments such as the atomic energy industry, to complete the handling or process operations of materials harmful to the human body, in developed countries, complete sets of industrial robot automated production line equipment have become the mainstream of automated equipment and the future development direction. Foreign automotive industry, electronic and electrical industry, engineering machinery and other industries have already used industrial robot automated production lines on a large scale to ensure product quality, improve production efficiency, and avoid a large number of industrial accidents. In traditional engineering, the jaws used for clamping parts are generally manual jaws, including jaws and jaw adjustment and fastening devices. During use, the jaws generally clamp the workpiece first. Generally, the motion trajectory of the mechanical jaws is relatively simple, which makes it inconvenient to use in some industrial applications to clamp objects.

[0004] In the existing technology, with the increase in labor costs and the reduction in human resources, the manufacturing equipment industry has put forward higher requirements on the automation level of production lines, and more and more industrial robots are used for automatic loading and unloading, positioning, assembly and transportation. Especially in some power equipment industries, most parts are castings, the product appearance is complex and the precision is low, and the automatic positioning and assembly of parts are difficult.

[0005] In the process of realizing the present utility model, the inventors found that the prior art has the following problems: 1. Industrial robots replace humans to do certain monotonous, frequent and repetitive long-term operations, but the existing grippers can only perform some single movements, resulting in the inability to pick up some special angles, which makes picking up inconvenient; 2. Industrial robots can replace some simple operations of humans in industrial production. The grippers generally rely solely on programming for limiting the position, but when the computer crashes, it is easy for the mechanical grippers to move arbitrarily, causing the mechanical grippers to collide and be damaged, thereby causing damage to the grippers. Utility Model Content

[0006] The purpose of the utility model is to provide a clamping jaw assembly with a double limit structure, so as to solve the problem that the existing clamping jaws can only move in a single way, which makes it difficult to pick up items at certain special angles. To achieve the above purpose, the utility model provides the following technical solution: the clamping jaw assembly with a double limit structure includes a fixing plate, a connecting rod is connected to one side of the fixing plate through a latch, and a connecting plate is connected to one side of the connecting rod through a latch.

[0007] The fixed plate includes a cylinder, the output shaft of the cylinder is plug-connected with a rack, a first slide groove is fitted and connected below the rack, a second slide groove is welded and connected in front of the fixed plate, a slider is fitted inside the second slide groove, a third slide groove is welded above the slider, and a limiting plate is welded above the fixed plate.

[0008] Further preferably, the connecting rod includes a limiting groove, a rotating handle is connected to the top of the connecting rod through a pin, the pin of the rotating handle is connected to the center of the first gear, a rotating plate is connected to the center of the limiting groove, a fixed shaft is fitted inside the hole of the rotating plate, a turntable is connected to the corner of the limiting groove through a pin, a first motor is installed at the rear of the limiting groove through screws, and the rotating plate forms a rotating structure through the first motor, and the fixed shaft forms a sliding structure through the rotating plate and the limiting groove.

[0009] Further preferably, the connecting plate includes a second motor, the output shaft of the second motor is plugged into the central part of the second gear, the third gear is meshed below the second gear, the pin of the third gear is plugged into one end of the folding plate, the outer wall of the folding plate is plugged into an auxiliary plate, a splint is welded below the folding plate, one side of the splint is attached with an anti-slip pad, one side of the third gear is meshed and connected with an incomplete gear, one side of the connecting plate is attached with a slide plate, the second gear forms a rotating structure through the second motor, and the incomplete gear forms a rotating structure through the second gear.

[0010] Further preferably, the rotating handle forms a rotating structure through the first gear, and the connecting rod forms a sliding structure through the third sliding groove.

[0011] Further preferably, the rack forms a sliding structure with the first sliding groove through a cylinder.

[0012] Further preferably, the third sliding groove forms a sliding structure with the second sliding groove through a sliding block.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, industrial robots are generally used for some repetitive work in industrial processing, which is convenient for improving efficiency. Clamps are often used. Some repetitive industrial work is generally performed manually, which leads to the handling of some harmful materials, easy injuries, and hand damage. Now the improvement replaces the manual use with clamps. The first motor rotates the rotating plate, and the rotating plate moves inside the limit groove. The fixed shaft moves with the hole of the rotating plate, so that the rotating plate moves along the specified limit groove, which is convenient for adjusting the angle of movement.

[0015] In the utility model, the industrial robot can replace some simple operations of people in industrial production, but once the power is off or the computer crashes, the mechanical clamp is easy to slip and cause damage. Now the improved cylinder drives the rack to move inside the first slide groove, and the first gear on the first slide groove rotates, which is convenient for the hanging rod to move in the third slide groove, and the limit plate limits the position to prevent the computer from crashing and moving.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 5 The utility model provides a technical solution: a clamping jaw assembly with a double limiting structure includes a fixing plate 1, a connecting rod 2 is plugged into one side of the fixing plate 1 through a latch, and a connecting plate 3 is plugged into one side of the connecting rod 2 through a latch.

[0024] The fixed plate 1 includes a cylinder 101, the output shaft of the cylinder 101 is plugged and connected with a rack 102, the lower part of the rack 102 is fitted with a first slide groove 103, the front of the fixed plate 1 is welded with a second slide groove 104, the interior of the second slide groove 104 is fitted with a slider 107, the upper part of the slider 107 is welded with a third slide groove 106, and the upper part of the fixed plate 1 is welded with a limiting plate 105.

[0025] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the connecting rod 2 includes a limiting groove 206, a rotating handle 201 is plugged into the top of the connecting rod 2 through a latch, the latch of the rotating handle 201 is plugged into the center of the first gear 202, a rotating plate 204 is plugged into the center of the limiting groove 206, a fixed shaft 205 is fitted inside the hole of the rotating plate 204, a rotating disk 207 is plugged into the corner of the limiting groove 206 through a latch, a first motor 203 is installed behind the limiting groove 206 through screws, and the rotating plate 204 forms a rotating structure through the first motor 203, and the fixed shaft 205 forms a sliding structure with the limiting groove 206 through the rotating plate 204; because industrial robots can replace people to do some monotonous, frequent and repetitive long-term operations in industrial production, or dangerous and harsh environments In operations under certain conditions, such as stamping, pressure casting, heat treatment, welding, painting, plastic product forming, machining and simple assembly, it is necessary to use a clamp to clamp objects instead of manually moving objects. Generally, the commonly used clamp can only move downward and horizontally to clamp objects, resulting in objects at some angles being limited when they need to move 90°. Now the improvement can maximize the limit adjustment angle for movement, grab objects, the first motor 203 rotates the turn plate 204, the turn plate 204 moves inside the limit slot 206, the fixed shaft 205 moves with the hole of the turn plate 204, so that the turn plate 204 moves along the specified limit slot 206, and limits are performed, which is convenient for adjusting the rotation and placement of objects, thereby achieving the effect of rotating the turn plate 204.

[0026] In this embodiment, Figure 1 , Figure 2 and Figure 5 As shown, the connecting plate 3 includes a second motor 302, the output shaft of the second motor 302 is plugged with the central part of the second gear 303, the lower part of the second gear 303 is meshed with a third gear 304, the latch of the third gear 304 is plugged with one end of a folding plate 306, the outer wall of the folding plate 306 is plugged with an auxiliary plate 307, a clamping plate 308 is welded below the folding plate 306, one side of the clamping plate 308 is attached with an anti-slip pad 309, one side of the third gear 304 is meshed and connected with an incomplete gear 305, one side of the connecting plate 3 is attached with a slide plate 301, and the second gear 303 forms a rotating structure through the second motor 302, and the incomplete gear 305 forms a rotating structure through the second gear 303; because industrial robots are generally used for some repetitive industrial processing In order to improve the work efficiency, the clamps are often used. Some repetitive industrial work is generally performed manually, which leads to the handling of some harmful materials, easy injuries and hand damage. Now the improvement is to use the clamps instead of manual work to simulate the hand handling. The second motor 302 is used to rotate the second gear 303 on the connecting plate 3, the second gear 303 rotates the third gear 304, the third gear 304 rotates the incomplete gear 305, the incomplete gear 305 is limited to clamp and put down, the third gear 304 and the incomplete gear 305 drive the two folding plates 306 to open and close, the auxiliary plate 307 assists in opening and closing, the clamp 308 is provided with an anti-slip pad 309 to prevent falling, so as to facilitate the clamping and putting down of objects, thereby achieving the opening and closing of the clamp 308.

[0027] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rotating handle 201 forms a rotating structure through the first gear 202, and the connecting rod 2 forms a sliding structure through the third slide groove 106; because industrial robots are generally used in industry to replace some relatively dangerous jobs, it is convenient to improve the efficiency of workers' repetitive work. Generally, factory work is manually operated, resulting in low efficiency. Long-term operation can cause muscle and joint injuries. A clamp is used to simulate the hand gripping of objects. Generally, the clamp can only perform some simple movements up, down, left and right, but some special positions cannot be moved, which is inconvenient to use. Now the improved rotating handle 201 rotates through the first gear 202, and the rotating handle 201 rotates the connecting rod 2, and the connecting rod 2 moves up and down inside the third slide groove 106, thereby achieving the linkage effect of the connecting rod 2 and the limit groove 206.

[0028] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the rack 102 forms a sliding structure with the first slide groove 103 through the cylinder 101; because the industrial robot needs to be composed of some programming and mechanical parts and is used inside the factory, some processing operations of some items are relatively repetitive, and they are used for transportation, moving, welding, etc., which are easy to process. Existing industrial robots generally use mechanical claws, which can only do some relatively simple tasks and have no limit device. They rely solely on programming for limiting. However, when the computer crashes, it is easy to cause the mechanical claw to move arbitrarily, causing the mechanical claw to collide and cause damage. Now the improvement is that the rack 102 is driven by the cylinder 101 to move inside the first slide groove 103, and the first gear 202 on the first slide groove 103 rotates, which is convenient for the connecting rod 2 to move in the third slide groove 106, and the limit plate 105 limits the position to avoid computer crash and movement, thereby achieving the effect of moving the rack 102.

[0029] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the third slide groove 106 forms a sliding structure with the second slide groove 104 through the slider 107; because the industrial robot needs to be composed of some programming and mechanical parts and is used inside the factory, some processing operations of items are relatively repetitive, and the mechanical claw is provided with a tensioning effect, but it is impossible to adjust different angles. Now the improved connecting rod 2 drives the slider 107 under the third slide groove 106 to move inside the second slide groove 104, which is convenient for adjusting the distance, thereby achieving the effect of moving the second slide groove 104.

[0030] The use method and advantages of the utility model: When the clamping jaw assembly with a double limit structure is used, the working process is as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, first, the second motor 302 rotates the second gear 303 on the connecting plate 3, the second gear 303 rotates the third gear 304, the third gear 304 rotates the incomplete gear 305, the incomplete gear 305 performs limit clamping and lowering, and the two folding plates 306 are driven to open and close through the third gear 304 and the incomplete gear 305, the auxiliary plate 307 assists in opening and closing, the clamping plate 308 is provided with an anti-slip pad 309 to prevent falling, the cylinder 101 connected to the fixed plate 1 drives the rack 102 to move inside the first slide groove 103, the first gear 202 on the first slide groove 103 rotates, so that the connecting rod 2 can move in the third slide groove 106, the limit plate 105 limits the position, the handle 201 is turned to rotate through the first gear 202, the handle 201 rotates to rotate the connecting rod 2, the connecting rod 2 moves up and down inside the third slide groove 106, and the connecting rod 2 drives the slider under the third slide groove 106 107 moves inside the second slide groove 104, so that the slider 107 drives the third slide groove 106 to move, and the connecting rod 2 can move up and down inside the third slide groove 106, and the first motor 203 rotates the rotating plate 204, and the rotating plate 204 moves inside the limiting groove 206, and the fixed shaft 205 moves along the hole of the rotating plate 204, so that the rotating plate 204 moves along the specified limiting groove 206, and the slide plate 301 rotates along the fixed shaft 205 through the turntable 207, and the second motor 302 rotates the second gear 303 on the connecting plate 3, and the second gear 303 rotates the third gear 304, and the third gear 304 rotates the incomplete gear 305, and the incomplete gear 305 performs limiting clamping and lowering, and the two folding plates 306 are driven to open and close through the third gear 304 and the incomplete gear 305, and the auxiliary plate 307 assists in opening and closing, and the clamping plate 308 is provided with an anti-slip pad 309 to prevent falling.
