Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a multifunctional die-casting clamping claw. Background Art

[0002] With the popularization of lightweight auto parts, die-cast aluminum alloy and die-cast magnesium alloy auto parts are more and more widely used. During the die-casting production of automotive steering wheels, die-casting grippers cooperate with industrial robots to meet the needs of automatic grasping of parts to replace manual operations, improve efficiency and process stability, and provide hardware guarantees for product quality. They can firmly clamp metal molds and tackle tough problems to ensure that they will not move or shake during the die-casting process.

[0003] At present, before the present design, the existing die-casting grippers have the following die-casting production process for steering wheels: die-casting, mold opening, robot picking up parts, manual spraying of release agent, manual placement of core inserts, mold closing, and die-casting. The main disadvantage of this method is that it cannot achieve fully automated production operations, and the use of robots and manual labor at the same time will also have certain safety hazards, which is not conducive to improving production efficiency. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the utility model provides a multifunctional die-casting clamp, which can realize loading and release agent spraying while the robot is picking up the parts, replacing the risks and cumbersome operation of manual operation, and solving the problems of low efficiency and safety hazards in manual loading and spraying of release agents.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multifunctional die-casting clamp, comprising an arm assembly, a first clamping assembly and a second clamping assembly, wherein the arm assembly comprises an L-shaped arm plate, a mounting panel is fixed at one end of the L-shaped arm plate, the L-shaped arm plate is mounted on a mechanical arm through a fixing member, and the mechanical arm drives the device as a whole to turn, move and tilt, and process the steering wheel;

[0008] The first clamping assembly includes a large clamping cylinder fixed to the side of the L-shaped arm plate, and a large clamping claw is installed on the output end of the large clamping cylinder. After the large clamping cylinder is operated, the large clamping claw clamps the steering wheel toward the middle, and the large clamping claw expands outward, so that the steering wheel can be disassembled;

[0009] The second clamping assembly includes a positioning plate fixed on the mounting panel, a linear cylinder is fixed on the positioning plate, a small clamping cylinder is fixed on the output end of the linear cylinder, a small clamping claw is fixed on the output end of the small clamping cylinder, an iron core insert is clamped between the small clamping claws, and the positioning plate is fixed to the mounting panel by screws, and is used to fix the second clamping assembly as a whole to the L-shaped arm plate.

[0010] When the die-casting grippers are performing grasping, spraying, and picking up and placing the core inserts and steering wheels, the robotic arm is started, and the robotic arm operates according to the set route to drive the overall operation of the device. After the steering wheel is produced and the mold is opened, the robotic arm moves to the mold cavity, and controls the large clamping cylinder to expand the large clamping jaw, corresponding to the top of the mold, and controls the output end of the large clamping cylinder to operate so that the large clamping jaw clamps toward the middle. After clamping and fixing the steering wheel, the robotic arm is controlled to operate, and the steering wheel is demolded from the middle of the mold cavity and taken out. At this time, the robotic arm is controlled to rotate one circle, and the robotic arm is controlled to align the release agent control valve and the compression control valve in the mold cavity. At this time, the robot is controlled to send a signal to open the relevant release agent control valve and compressed air control valve, so that the release agent and compressed air are mixed in the sprayer and released from the sprayer. The installed nozzle is used to spray the release agent on specific parts in the mold in advance. After the spraying is completed, the linear cylinder is controlled to operate, the core insert is aligned with the top of the lower template cavity of the mold, and the robot arm is moved downward to make the bottom of the core insert fit in the lower mold cavity. The small clamping cylinder is controlled to operate and the small clamping claw is controlled to expand to place the core insert in the lower mold cavity. After the prevention is completed, the robot arm is controlled to move to completely separate the L-shaped arm plate from the upper and lower molds, and the robot arm rotates in the opposite direction to return the large clamping claw and the small clamping claw to the initial position. At this time, after the upper and lower molds are closed, the core insert is die-cast, and the upper and lower molds are expanded again, and the robot arm moves into the mold cavity again, and the die-cast steering wheel is clamped by the large clamping claw and moved out of the mold. Then the above steps are repeated to complete the assembly line production process of the steering wheel.

[0011] As a further improvement of the above solution, a triangular plate is fixed to the side of the L-shaped arm plate;

[0012] Through the above technical solution, the triangle plate is attached to the inner side of the L-shaped arm plate, which increases the stability of the L-shaped arm plate and avoids the L-shaped arm plate from swinging slightly during operation, thereby preventing the swing from affecting the processing accuracy.

[0013] As a further improvement of the above solution, a positioning hole is provided at one end of the L-shaped arm plate;

[0014] Through the above technical solution, a fixing screw is sleeved in the positioning hole, and the L-shaped arm plate is fixed to the front end of the robotic arm through the fixing screw, so that the robotic arm can drive the overall smooth movement of the device when it is in operation.

[0015] As a further improvement of the above solution, the first clamping assembly and the second clamping assembly are installed in reverse order;

[0016] Through the above technical solution, the first clamping assembly is used to clamp and fix the steering wheel, and the second clamping assembly is used to clamp and fix the core insert. Through the reverse installation design, when the robotic arm is rotating, the steering wheel can be taken out and then turned again to input the core insert into the mold for die-casting.

[0017] As a further improvement of the above solution, the large clamping cylinder and the small clamping cylinder are both three-claw cylinders;

[0018] Through the above technical solution, corresponding clamping claws are installed at the output ends of the large and small clamping cylinders, and the clamping claws clamp the corresponding components through the operation of the cylinders.

[0019] As a further improvement of the above solution, a sprayer is fixed on the positioning plate;

[0020] Through the above technical solution, the sprayer is used to spray the release agent on the designated position in the mold, thereby improving the demoulding efficiency of the die-cast steering wheel.

[0021] As a further improvement of the above solution, an ejection mechanism is fixed to the side of the positioning plate, and a stabilizing plate is fixed to the side of the linear cylinder, and the stabilizing plate is attached to the side of the ejection mechanism;

[0022] Through the above technical solution, the ejection mechanism is located on both sides of the stabilizing plate, which improves the stability of the telescopic movement of the output end when the linear cylinder is operating, thereby achieving the effect of precise feeding.

[0023] Compared with the prior art, the utility model provides a multifunctional die-casting clamping jaw, which has the following beneficial effects:

[0024] 1. The multifunctional die-casting clamp is installed on an L-shaped arm plate on the basis of a first clamping component for picking up the steering wheel. In addition, a second clamping component for loading the core insert is installed in the opposite direction. After the steering wheel is unloaded by the first clamping component, the mechanical arm is flipped. At this time, the second clamping component places the clamped core insert in the mold, thereby achieving the effect of autonomous loading on the basis of traditional picking up, improving the efficiency of steering wheel production and processing, and effectively reducing the occurrence of safety hazards.

[0025] 2. The multifunctional die-casting clamp is equipped with a sprayer next to the second clamping component. Before loading, the sprayer is used to spray a release agent on a specific position in the mold cavity, and then the second clamping component places the core insert in the cavity. After die-casting, when the mold is opened, the steering wheel can be quickly demolded, realizing fully automatic loading and unloading, further improving production efficiency, and further reducing the occurrence of safety hazards.

[0033] 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 technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Embodiment 1

[0035] See also Figure 1-3As shown, the multifunctional die-casting clamp proposed in this embodiment includes an arm assembly 1, a first clamping assembly 2 and a second clamping assembly 3. The arm assembly 1 includes an L-shaped arm plate 101, and a mounting panel 104 is fixed at one end of the L-shaped arm plate 101. A fixing interface is reserved at the tail end of the L-shaped arm plate 101, and the L-shaped arm plate 101 is mounted on the robot arm through a fixing member, so that the L-shaped arm plate 101 and the robot arm are in a horizontal line. By setting the operation action of the robot arm and controlling the operation of the robot arm, the components installed on the L-shaped arm are driven by the robot arm to turn, move and tilt, thereby completing the loading and unloading processing of the steering wheel;

[0036] The first clamping assembly 2 includes a large clamping cylinder 201 fixed to the side of the L-shaped arm plate 101, and a large clamping claw 202 is installed on the output end of the large clamping cylinder 201. After the large clamping cylinder 201 is operated, the large clamping claw 202 clamps the steering wheel toward the middle to prevent the steering wheel from falling off, and the large clamping claw 202 expands outwards, causing the steering wheel to lose its fixing force, and the steering wheel can be removed at this time;

[0037] The second clamping assembly 3 includes a positioning plate 301 fixed on the mounting panel 104, a linear cylinder 302 is fixed on the positioning plate 301, a small clamping cylinder 303 is fixed on the output end of the linear cylinder 302, a small clamping claw 304 is fixed on the output end of the small clamping cylinder 303, and a core insert 305 is clamped between the small clamping claws 304. The positioning plate 301 is fixed to the mounting panel 104 by screws, and is used to fix the second clamping assembly 3 as a whole to the L-shaped arm plate 101. When the output end of the small clamping cylinder 303 is telescopically moved, the small clamping claw 304 is expanded outward or clamped toward the middle, so that the core insert 305 is clamped and sent to the mold cavity. Then, the small clamping claw 304 is expanded to place the core insert 305 in the mold cavity, thereby achieving the effect of loading.

[0038] The working principle of the multifunctional die-casting clamp proposed in this embodiment is: when in use, by starting the mechanical arm, the mechanical arm operates according to the set route to drive the overall operation of the device. After the steering wheel is produced and the mold is opened, the mechanical arm moves to the mold cavity, and controls the large clamping cylinder 201 to expand the large clamping claw 202, corresponding to the top of the mold, and controls the output end of the large clamping cylinder 201 to operate so that the large clamping claw 202 clamps toward the middle. After the steering wheel is clamped and fixed, the mechanical arm is controlled to operate, and the steering wheel is demolded from the middle of the mold cavity and taken out. At this time, by controlling the mechanical arm to rotate one circle, and controlling the mechanical arm to align the release agent control valve and the compression control valve in the mold cavity, at this time, the control robot sends a signal to open the relevant release agent control valve and compressed air control valve, so that the release agent and compressed air are mixed in the sprayer 306 and discharged from the installed sprayer The nozzle is used to spray the release agent on the specific parts in the mold in advance. After the spraying is completed, the linear cylinder 302 is controlled to operate, and the core insert 305 is aligned with the top of the lower template cavity of the mold, and the robot arm is moved downward to make the bottom of the core insert fit in the lower mold cavity. The small clamping cylinder 303 is controlled to operate and the small clamping claw 304 is controlled to expand to place the core insert in the lower mold cavity. After the prevention is completed, the robot arm is controlled to move to completely separate the L-shaped arm plate 101 from the upper and lower molds, and the robot arm rotates in the opposite direction to return the large clamping claw 202 and the small clamping claw 304 to their initial positions. At this time, after the upper and lower molds are closed, the core insert is die-cast, and the upper and lower molds are expanded again, and the robot arm moves into the mold cavity again, and the die-cast steering wheel is clamped by the large clamping claw and moved out of the mold, and then the above steps are repeated to complete the assembly line production process of the steering wheel.

[0039] Embodiment 2

[0040] See also Figure 1-3 As shown, the multifunctional die-casting clamp mentioned in this embodiment, on the basis of the first embodiment, further comprises: a triangular plate 102 is fixed to the side of the L-shaped arm plate 101, a positioning hole 103 is opened at one end of the L-shaped arm plate 101, the first clamping assembly 2 and the second clamping assembly 3 are installed in reverse, the large clamping cylinder 201 and the small clamping cylinder 303 are both three-claw cylinders, a sprayer 306 is fixed on the positioning plate 301, an ejection mechanism 307 is fixed to the side of the positioning plate 301, and a stabilizing plate 3021 is fixed to the side of the linear cylinder 302, and the stabilizing plate 3021 is attached to the side of the ejection mechanism 307;

[0041] In the present solution, the triangle plate 102 is fitted on the inner side of the L-shaped arm plate 101, so as to increase the stability of the L-shaped arm plate 101 and prevent the L-shaped arm plate 101 from bending and slight swinging during operation, so as to prevent the swinging from affecting the processing accuracy and stability. A fixing screw is sleeved in the positioning hole 103, and the fixing screw is sleeved in the positioning hole 103 and fixed to the mechanical arm by rotation, so as to fix the L-shaped arm plate 101 to the front end of the mechanical arm, so that the mechanical arm can drive the overall smooth movement of the device during operation. The first clamping component 2 is used to clamp and fix the steering wheel, and the second clamping component 3 is used to clamp and fix the core insert 305. By designing that the first clamping component 2 and the second clamping component 3 are installed in reverse, the large and small jaws can be switched when the mechanical arm is rotating. The steering wheel is clamped by the large jaw 202 After taking out, it turns 360 degrees again and inputs the clamped core insert 305 into the mold for die-casting. The output ends of the large and small clamping cylinders are equipped with corresponding claws, which are operated by the cylinders to clamp the corresponding components. The sprayer 306 is used to spray a release agent on a specified position in the mold. The release agent is a chemical substance used to help easily release the mold or workpiece from the mold surface during the manufacturing process. In die-casting, injection molding, compression molding and other processes, the release agent can reduce the friction between the mold and the workpiece, prevent adhesion and damage, so that the steering wheel after die-casting can be separated from the mold cavity, thereby improving the production efficiency of the steering wheel and ensuring the product quality of the steering wheel after production, and improving the demolding efficiency of the die-cast steering wheel. The ejection mechanism 307 is located on both sides of the stabilizing plate 3021. When the linear cylinder 302 is operating, the stability of the telescopic movement of the output end is improved to achieve the effect of precise feeding.
