Abstract

This invention relates to the field of robotic arm technology, specifically to a robotic arm mechanism for forging a fully welded valve cover. It includes a cleaning mechanism for removing waste residue from the surface of the valve cover blank. The mechanism comprises two sets of rotating shafts, each with a gear fixedly mounted on it. Connecting rods are fixedly connected to both sides of the gears on each shaft. A striking block is hinged to the end of each connecting rod. An arc-shaped block is slidably inserted between the two sets of connecting rods. A connecting block is fixedly mounted to one end of the arc-shaped block, and limit blocks are fixedly mounted on both the upper and lower sides of the connecting block. This invention, by setting up a driving component and a cleaning component, allows the driving component to control the cleaning component to perform reciprocating rotational motion, thereby causing the striking block to repeatedly strike the blank, causing the waste residue on the blank to fall off.

Description

Technical Field

[0001] This invention relates to the field of robotic arm technology, specifically to a fully welded valve cover forging robotic arm mechanism. Background Technology

[0002] During the valve cover forging process, repeated processing and switching between two stations are required. The robotic arm takes the billet out of the heating furnace, transports it to the forging press for forging processes such as upsetting and punching, and it still needs to be reheated in the furnace once during this process. After the billet is forged, some waste residue will be generated on its surface. Although some of it will fall directly onto the forging press, some of it will still stick to the billet. When the robotic arm transports the forged billet, some waste residue will fall into the moving section, which will affect the movement of the robotic arm, causing the robotic arm to bump during the movement and affecting the processing environment of valve cover forging. Summary of the Invention

[0011] Furthermore, the drive mechanism also includes a main housing that is fixedly connected to the telescopic end of the electric push rod b. Four sets of push rods are slidably inserted in a rectangular shape at equal intervals inside the main housing. Each of the four sets of push rods is hinged to a connector at one end. The end of one set of push rods near the support is connected to the telescopic end of the electric push rod a.

[0012] Furthermore, two sets of sub-shells are symmetrically installed on both sides of the main shell, and the two sets of toothed rods are slidably inserted into the two sets of sub-shells respectively, and the ends of the two sets of toothed rods are fixedly connected to the ends of the two sets of push rods respectively, and the connecting block is fixedly connected to the sub-shells.

[0015] Furthermore, the bottom of the support base plate is provided with two sets of limiting grooves, and the tension rope is wound around two sets of winding shafts through the limiting grooves.

[0016] Furthermore, a push plate is fixedly connected to the end of the push rod located away from the electric push rod a.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to embodiments.

[0036] Example:

[0037] A fully welded valve cover forging robot mechanism includes a walking mechanism 1, a frame 101 mounted on the walking mechanism 1, a body 102 mounted on the frame 101, a lifting mechanism 103 for controlling the lifting and lowering of the body 102 connected to the top of the frame 101, a clamping mechanism 104 mounted on one side of the body 102, and a cleaning mechanism 4 for cleaning waste residue from the surface of the valve cover blank mounted on one side of the body 102.

[0038] See attached document Figure 1 Appendix Figure 2 Appendix Figure 4 -Appendix Figure 6As shown, the cleaning mechanism 4 includes two sets of rotating shafts 401. The rotating shafts 401 transmit the rotational force of the gears 402, thereby controlling the rotation of the connecting rods 403. The gears 402 are fixedly sleeved on the rotating shafts 401. By setting the gears 402, the horizontally moving rack 305 drives the gears 402 to rotate. Connecting rods 403 are fixedly connected to the rotating shafts 401 on both sides of the gears 402. The ends of the connecting rods 403 are provided with movable grooves that allow the striking blocks 405 to rotate 120 degrees. The same set of fixing members 404 are fixedly sleeved on the two sets of connecting rods 403. By setting the fixing members 404, one end of the two sets of connecting rods 403 is supported, preventing the connecting rods 403 from deforming due to the weight of the striking blocks 405 during long-term use, thereby helping to extend the service life of the components. The ends of the connecting rods 403 are hinged to the striking blocks 405. By setting the striking blocks 405, the rotating striking blocks 405 can adjust the shape of the blank. The rotating adjustment is performed, and the striking block 405 strikes the blank, causing the waste residue to fall off the blank. An arc-shaped block 407 is slidably inserted between the two sets of connecting rods 403. By setting the arc-shaped block 407, the arc-shaped block 407 supports the connecting rod 403 and maintains the balance of the connecting rod 403. A connecting block 406 is fixedly installed at one end of the arc-shaped block 407. Limiting blocks 408 are fixedly installed on both the upper and lower sides of the connecting block 406. By setting the limiting blocks 408, the limiting blocks 408 restrict the rotation range of the connecting rod 403 and prevent the connecting rod 403 from over-rotating due to the rotation deviation of the gear 402. Specifically, when the rack 305 moves horizontally reciprocating, it drives the gear 402 to rotate, which in turn drives the rotating shaft 401 to rotate. The connecting rod 403 rotates together with it. The reciprocating rotating connecting rod 403 strikes the blank with the striking block 405, thereby achieving the purpose of cleaning the waste residue on the blank.

[0039] Drive mechanism 3 is used to drive cleaning mechanism 4 to reciprocate and strike the blank. Drive mechanism 3 includes two sets of racks 305 for driving gear 402 to rotate, and also includes main housing 301. Four sets of push rods 302 are equidistantly slidably inserted into the main housing 301. Each of the four sets of push rods 302 is hinged to a connector 303 at opposite ends. By setting the connectors 303, the four sets of push rods 302 are linked together. The end of one set of push rods 302 near support base 206 is connected to electric push rod a207. The telescopic ends are connected, and a push plate 306 is fixedly connected to the end of a set of push rods 302 that are away from the electric push rod a207. Specifically, when the electric push rod a207 pushes a set of push rods 302, the other three sets of push rods 302 move synchronously through the connecting piece 303. The two sets of push rods 302 control the rack 305 to drive the gear 402 to rotate. When the push rods 302 on both sides retract, the connecting rod 403 drives the knocking block 405 to rotate away from the blank, and the corresponding push rod 302 pushes the push plate 306 to come close to the blank for positioning.

[0040] Two sets of sub-shells 304 are symmetrically installed on both sides of the main shell 301. By setting the sub-shells 304, the positions of the rack 305 and the cleaning mechanism 4 are fixed. The two sets of racks 305 are slidably inserted into the two sets of sub-shells 304 respectively, and the ends of the two sets of racks 305 are fixedly connected to the ends of the two sets of push rods 302 respectively. The connecting block 406 is fixedly connected to the sub-shells 304.

[0041] See attached document Figure 1 -Appendix Figure 4As shown, the lifting mechanism 2, used to control the lifting of the drive mechanism 3 and the cleaning mechanism 4, includes two sets of fixed seats 201 fixedly mounted on the frame 101. Each fixed seat 201 houses a motor, and the motor's output shaft is coaxially connected to a take-up shaft 202. A partition 203 is fixedly mounted on the take-up shaft 202. The partition 203 separates the two sets of tension ropes 204, preventing them from tangling during rotation and thus affecting normal operation. Tension ropes 204 are respectively installed on the take-up shaft 202 on both sides of the partition 203, controlling the support base plate. The lifting and lowering mechanism 205 is supported by two sets of tension ropes 204, each with a supporting base plate 205. The supporting base plate 205 supports the drive mechanism 3 and the cleaning mechanism 4. Two sets of limiting grooves 2052 are provided at the bottom of the supporting base plate 205. The tension ropes 204 wind around two sets of take-up shafts 202 through the limiting grooves 2052. The limiting grooves 2052 limit the tension ropes 204, thus helping them to stably drive the lifting and lowering of the supporting base plate 205. Two sets of limiting rods 209 are fixedly installed on one side of the frame 101. The supporting base plate 205 slides on the two sets of limiting rods 209, thus limiting the movement of the tension ropes. Rod 209 limits the lifting trajectory of the support base plate 205 to prevent swaying during lifting. A support base 206 is fixedly installed on the support base plate 205. An electric push rod a207 is fixedly installed on one side of the support base 206. The electric push rod a207 drives the reciprocating motion of the push rod 302. Two sets of electric push rods b208 are fixedly installed on the support base 206 on both sides of the electric push rod a207. The telescopic ends of the electric push rods b208 are fixedly connected to the main housing 301. The electric push rods b208 control the movement of the main housing 301, thereby controlling the distance between the push plate 306 and the blank. Two sets of track grooves 2051 are provided on the upper part, which restrict the range of motion of the main housing 301. Two sets of slide rails 3011 are fixedly connected to the bottom of the main housing 301. The slide rails 3011 are slidably installed in the track grooves 2051. By setting the slide rails 3011, it helps to strengthen the connection between the main housing 301 and the support base plate 205 and avoid slippage when the position moves. Specifically, when the clamping mechanism 104 flips the blank, the motor is started to control the winding shaft 202 to rotate. The winding shaft 202 winds up the tension rope 204, and the tension rope 204 pulls the support base plate 205 up, giving the clamping mechanism 104 enough rotation space.

[0042] Specifically, the robotic arm moves to the vicinity of the blank via the walking mechanism 1. When it is necessary to clean the waste residue on the blank, the clamping mechanism 104 clamps the blank, and the electric push rod b208 pushes the main housing 301 to move within the limiting groove 2052, so that the push plate 306 is close to the blank. The electric push rod a207 controls the push rod 302 to reciprocate. When the push rod 302 in the vertical direction on the side of the blank moves inward, the push rod 302 in the parallel direction pushes the rack 305 to move outward. The rack 305 rotates the gear 402, thereby causing the gear to rotate. 402 drives the rotating shaft 401 to rotate, and the connecting rod 403 rotates together. The reciprocating rotating connecting rod 403 strikes the blank material through the striking block 405, causing the waste material to fall off the blank material. When the clamping mechanism 104 needs to rotate the blank material, the electric push rod b208 pulls the main housing 301 inward, thereby moving the cleaning mechanism 4 away from the blank material. The motor is started to control the winding shaft 202 to rotate. The winding shaft 202 winds up the tension rope 204. The tension rope 204 pulls the support base plate 205 to rise, giving the clamping mechanism 104 sufficient rotation space.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
