Description

Technical Field

[0001] This utility model relates to the field of die-casting gripper technology, specifically a die-casting gripper with a rotating function. Background Technology

[0002] Die-casting grippers are mechanical devices used to clamp and hold workpieces, commonly found in industrial fields such as machining, automated production lines, and assembly lines. They typically consist of a gripper body, a clamping mechanism, a clamping handle, and a fixed base. The clamping mechanism is the key component of the die-casting gripper, used to clamp and release the workpiece. The clamping mechanism usually consists of a threaded rod, a nut, and a movable arm, and the clamping force is controlled by a handle or a pneumatic or hydraulic system. The design and performance of the clamping mechanism directly affect the gripping force and stability of the gripper.

[0003] Currently, in fully automated die-casting production, existing die-casting grippers have fixed grippers on the robot's arm. The grippers are at a fixed angle, forming a 90° right angle with the die-casting part. This prevents the die-casting part from being directly placed into the punching hydraulic press. Therefore, the traditional method is for the robot to place the die-casting part into a specially designed secondary positioning fixture after gripping it, then release the grippers, adjust the other direction to form an angle of about 0° with the original grippers, and grip the die-casting part again before placing it into the punching hydraulic press. This secondary clamping reduces the clamping accuracy of the robot, increases the manufacturing cost of the secondary positioning fixture, and extends the production cycle due to the need for secondary clamping, which is detrimental to the continuity of production. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a die-casting gripper with a rotating function, which can work with robots to achieve greater freedom and flexibility during operation. It enables the die-casting parts to be placed directly into the punching hydraulic press to complete the corresponding punching operation without the need for secondary clamping and positioning. This solves the problems of current die-casting grippers that require secondary clamping of die-casting parts for feeding, resulting in low precision, increased manufacturing costs of secondary positioning fixtures, and reduced production efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a die-casting gripper with a rotating function, comprising an arm assembly, a gripper assembly, an auxiliary assembly, and a die-casting part. The arm assembly includes a connecting arm, a rotating rod is movably hinged to one end of the connecting arm, and a mounting plate is fixed to one end of the rotating rod. The connecting arm is connected to the robotic arm by screws. When the robotic arm operates, it drives the connecting arm to operate simultaneously. At the same time, a circular hole is opened at the front end of the connecting arm, and the rotating rod is movably hinged in the circular hole, which improves the stability of the rotating rod driving the mounting plate to rotate.

[0008] The gripper assembly includes a fixed plate fixed to the mounting plate, an inner protective plate fixed to the fixed plate, an outer protective plate fixed to the side of the inner protective plate, and a fixed gripper hinged between the inner and outer protective plates. The fixed plate and the mounting plate are locked together by screws to prevent the gripper assembly from detaching from the connecting arm. The inner and outer protective plates are shaped to match each other, and when closed, two slots are reserved at both ends. Fixed grippers are hinged in the slots. The two grippers open and close to achieve the function of clamping and fixing the die-casting part and unfolding and picking it up.

[0009] The auxiliary component includes an auxiliary plate slidably connected to the side of the fixed gripper. The auxiliary plate has a slot, and an adsorption plate is movably connected in the slot. At the same time, a positioning screw is threaded to the side of the auxiliary plate, and one end of the positioning screw is threaded to the adsorption plate. When the fixed gripper clamps the component in the center, the adsorption plate adheres to the side of the component and adsorbs the contact surface of the component, thereby achieving adsorption and fixation and improving the stability of clamping the component.

[0010] The die-cast part is movably connected between the fixed jaws.

[0011] When loading and unloading die-casting parts, this rotating die-casting gripper controls the operation of a robotic arm, which moves the connecting arm. A cylinder reciprocates, pulling the rotating block backward until the gripper assembly and connecting arm are at a right angle. The robotic arm then moves the gripper assembly into the die-casting machine to pick up the casting. After leaving the die-casting machine, before being fed into the punching hydraulic press, the cylinder pushes the rotating block forward, bringing the gripper assembly and connecting arm to a horizontal 180° angle. This ensures the die-casting part is also horizontally aligned with the connecting arm, allowing it to be smoothly fed into the punching hydraulic press. After punching, the die-casting part is removed, and the fixed gripper unfolds to remove the clamped part.

[0012] As a further improvement to the above solution, an electric push rod is movably connected to the side of the connecting arm, a connecting rod is fixed to the output end of the electric push rod, a connecting piece is fixed to one end of the connecting rod, and a rotating block is fixed to one end of the rotating rod, with the connecting piece movably hinged to the rotating block.

[0013] Through the above technical solution, the electric push rod operates, causing its output end to drive the connecting rod to extend and retract simultaneously, which in turn causes the connecting part to drive the hinged rotating block to rotate, thereby realizing the rotation adjustment of the mounting plate installed at the front end of the rotating block.

[0014] As a further improvement to the above solution, a support plate is fixed to the side of the connecting arm, a fixing clamp is fixed to the support plate, and an electric push rod is fixed between the fixing clamps.

[0015] Through the above technical solution, the support plate plays a supporting role, while the fixing plate is used to clamp and fix the electric push rod, so that the electric push rod is fixed on the connecting arm, and the electric push rod is driven to operate at the same time when the connecting arm is operating.

[0016] As a further improvement to the above solution, a cylinder is fixed to one end of the inner and outer protective plates, and a linkage is fixed to one end of the fixed gripper. A connecting block is movably hinged to the linkage, and the output end of the cylinder is fixed to the connecting block.

[0017] Through the above technical solution, after the cylinder operates, its output end pushes and pulls the connecting block, thereby fixing the jaws to open and close, achieving the effect of clamping and unfolding the die-casting.

[0018] As a further improvement to the above solution, the side of the fixed gripper is movably hinged with a positioning rod, and the two ends of the positioning rod are respectively fixed to the inner guard plate and the outer guard plate.

[0019] Through the above technical solution, the positioning rod serves as the rotation point when the fixed gripper opens and closes. When the connecting block moves back and forth, the fixed gripper rotates around the positioning rod as the center.

[0020] As a further improvement to the above solution, a limiting groove is provided on the side of the fixed gripper, and a limiting pulley is fixed inside the auxiliary plate, with the limiting pulley slidably connected in the limiting groove.

[0021] Through the above technical solution, the auxiliary plate moves and adjusts on the side of the fixed jaw, so that the auxiliary plate can fit against the corresponding position on the side of the clamped die casting. When the position of the auxiliary plate is adjusted, the limiting pulley slides in the limiting groove, which improves the stability of the auxiliary plate during adjustment and movement.

[0022] As a further improvement to the above solution, a positioning groove is provided on the adsorption plate, and a suction cup is movably connected in the positioning groove, the suction cup adsorbing onto the side of the die-cast part.

[0023] With the above technical solution, when multiple positioning slots are equally spaced on the adsorption plate and each positioning slot is equipped with a suction cup, when the auxiliary plate is attached to the side of the die casting, the suction cup at the corresponding position can be adsorbed onto the die casting.

[0024] As a further improvement to the above solution, the bottom of the suction cup is fixed with an interconnecting connecting pipe, and a sleeve is movably sleeved on the side of the connecting pipe, with the sleeve threadedly connected in the positioning groove.

[0025] Through the above technical solution, the connecting pipe moves up and down within the sleeve, and the sleeve is threadedly connected to the center position within the positioning groove, thus preventing the suction cup from detaching from the positioning groove.

[0026] As a further improvement to the above solution, a branch pipe is fixed to the side of the auxiliary plate, and the branch pipe is interconnected with the sleeve pipe.

[0027] Through the above technical solution, one end of the pipe has a single interface, while the other end has multiple interfaces. The single interface is connected to an external fan, while the multiple interfaces are connected to a sleeve pipe to achieve the effects of air extraction and air blowing. When air is extracted, the suction cup is firmly attached to the side of the die-casting part, while when air is blown, the suction cup is detached from the side of the die-casting part.

[0028] As a further improvement to the above solution, a stabilizing rod is fixed to the bottom of the suction cup, the stabilizing rod is movably sleeved in the positioning groove, and a tension spring is movably sleeved on the side of the stabilizing rod, with both ends of the tension spring attached between the positioning groove and the suction cup.

[0029] Through the above technical solution, the tension spring pushes the suction cup upward, making the suction cup higher than the adsorption plate, so that it can better contact the side of the die-cast part for adsorption.

[0030] Compared with the prior art, this utility model provides a die-casting gripper with a rotating function, which has the following advantages:

[0031] 1. This die-casting gripper with a rotating function extends the connecting rod forward via the output end of an electric push rod, causing the rotating block to rotate. At this time, the front gripper assembly and the connecting arm are in a horizontal state. When the output end of the electric push rod retracts, the rotating rod rotates in the opposite direction, and the front gripper assembly and the connecting arm are in a right-angle state, thereby realizing the switching operation of the gripping angle. Through the operation of the cylinder, the gripper grips the die-casting part. Combined with the six degrees of freedom of traditional robots, it forms seven degrees of freedom, which can directly feed the die-casting part into the punching machine, effectively improving the gripping accuracy, reducing the manufacturing cost of secondary gripping, and improving the continuity and efficiency of production.

[0032] 2. The die-casting jaw with rotation function has an auxiliary plate installed on the jaw. During the clamping process, the suction cup is used to increase the clamping force and prevent slippage between the jaw and the die-casting part. At the same time, the position of the auxiliary plate on the jaw can be adjusted according to the size of the die-casting part, so that it can stably clamp die-casting parts of different sizes, thus improving the stability of the jaw holding.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Example 1

[0046] Please see Figure 1-6 As shown, the die-casting gripper with rotation function proposed in this embodiment includes an arm assembly 1, a gripper assembly 2, an auxiliary assembly 3, and a die-casting part 4. The arm assembly 1 includes a connecting arm 101, a rotating rod 106 is movably hinged to one end of the connecting arm 101, and a mounting plate 109 is fixed to one end of the rotating rod 106. The connecting arm 101 is connected to the robotic arm by screws. When the robotic arm operates, it drives the connecting arm to operate at the same time. At the same time, a circular hole is opened at the front end of the connecting arm 101, and the rotating rod 106 is movably hinged in the circular hole to improve the stability of the rotating rod 106 driving the mounting plate 109 to rotate.

[0047] The gripper assembly 2 includes a fixing plate 201 fixed on the mounting plate 109, an inner protective plate 202 fixed on the fixing plate 201, an outer protective plate 203 fixed on the side of the inner protective plate 202, and a fixed gripper 204 movably hinged between the inner protective plate 202 and the outer protective plate 203. The fixing plate 201 and the mounting plate 109 are locked together by screws to prevent the gripper assembly 2 from detaching from the connecting arm 101. The inner protective plate 202 and the outer protective plate 203 are shaped to match each other, and after closing, two grooves are reserved at both ends. The fixed gripper 204 is hinged in the grooves. The fixed gripper 204 opens and closes to achieve the function of clamping and fixing the die-casting part and unfolding and picking it up.

[0048] The auxiliary component 3 includes an auxiliary plate 301 slidably connected to the side of the fixed gripper 204. The auxiliary plate 301 has a slot 302, and an adsorption plate 303 is movably connected in the slot 302. At the same time, a positioning screw 306 is threadedly connected to the side of the auxiliary plate 301. One end of the positioning screw 306 is threadedly connected to the adsorption plate 303. When the fixed gripper 204 clamps the component in the middle, the adsorption plate 303 adheres to the side of the component and adsorbs the contact surface of the component, thereby achieving adsorption and fixation and improving the stability of clamping the component.

[0049] The die-cast part 4 is movably connected between the fixed jaws 204.

[0050] The working principle of the rotating die-casting gripper proposed in this embodiment is as follows: During use, the robotic arm is controlled to move the connecting arm 101. The cylinder 205 is controlled to operate, and the output end of the cylinder 205 reciprocates, causing the output end of the cylinder to pull the rotating block 107 backward until the gripper assembly 2 and the connecting arm 101 are at a right angle. At this time, the robotic arm operates, and the gripper assembly 2 enters the die-casting machine to clamp the casting. After leaving the die-casting machine, before being sent to the punching hydraulic press, the cylinder pushes the rotating block 107 forward, so that the gripper assembly 2 and the connecting arm 101 are at a horizontal 180° position. This makes the die-casting part also at a horizontal 180° position with the connecting arm 101. At this time, the die-casting part can be smoothly sent into the punching hydraulic press. After the punching work is completed, the die-casting part is taken out, and the fixed gripper 204 is controlled to unfold, and the clamped die-casting part can be removed.

[0051] Example 2

[0052] Please see Figure 1-6 As shown, the die-casting gripper with rotation function proposed in this embodiment, based on Embodiment 1, further includes an electric push rod 104 movably connected to the side of the connecting arm 101, a connecting rod 105 fixed to the output end of the electric push rod 104, a connecting member 108 fixed to one end of the connecting rod 105, and a rotating block 107 fixed to one end of the rotating rod 106. The connecting member 108 is movably hinged to the rotating block 107, and a support plate 10 is fixed to the side of the connecting arm 101. 2. A fixing clamp 103 is fixed on the support plate 102. An electric push rod 104 is fixed between the fixing clamps 103. A cylinder 205 is fixed to one end of the inner guard plate 202 and the outer guard plate 203. At the same time, a linkage 206 is fixed to one end of the fixing claw 204. A connecting block 207 is movably hinged to the linkage 206. The output end of the cylinder 205 is fixed to the connecting block 207. A positioning rod 208 is movably hinged to the side of the fixing claw 204. The two ends of the positioning rod 208 are... The clamping claw 204 is fixed to the inner protective plate 202 and the outer protective plate 203. A limiting groove 209 is provided on the side of the clamping claw 204. A limiting pulley 308 is fixed inside the auxiliary plate 301 and slidably connected to the limiting groove 209. A positioning groove 304 is provided on the adsorption plate 303, and a suction cup 305 is movably connected within the positioning groove 304. The suction cup 305 adsorbs onto the side of the die-cast part 4. A connecting pipe 311 is fixed to the bottom of the suction cup 305. A sleeve 312 is movably sleeved on the side of 11. The sleeve 312 is threaded into the positioning groove 304. A branch pipe 307 is fixed on the side of the auxiliary plate 301. The branch pipe 307 communicates with the sleeve 312. A stabilizing rod 309 is fixed at the bottom of the suction cup 305. The stabilizing rod 309 is movably sleeved in the positioning groove 304. At the same time, a tension spring 310 is movably sleeved on the side of the stabilizing rod 309. The two ends of the tension spring 310 are attached between the positioning groove 304 and the suction cup 305.

[0053] In this design, the electric push rod 104 operates, causing its output end to simultaneously extend and retract the connecting rod 105. This causes the connecting piece 108 to rotate the hinged rotating block 107, thus adjusting the rotation of the mounting plate 109 mounted on the front end of the rotating block 107. The support plate 102 provides support, while the fixing clamp 103 clamps and fixes the electric push rod 104, securing it to the connecting arm 101. This ensures that when the connecting arm 101 operates, it simultaneously drives the electric push rod 104. After the cylinder 205 operates... This causes the output end of the connecting block 207 to push and pull, thereby opening and closing the fixed gripper 204 to achieve the effect of clamping and unfolding the die-cast part 4. The positioning rod 208 serves as the rotation point of the fixed gripper 204 when it opens and closes. When the connecting block 207 moves back and forth, the fixed gripper 204 rotates around the positioning rod 208. The auxiliary plate 301 moves and adjusts on the side of the fixed gripper 204 so that the auxiliary plate 301 can fit against the corresponding position on the side of the clamped die-cast part. When the position of the auxiliary plate 301 is adjusted... During adjustment, the limiting pulley 308 slides in the limiting groove 209, improving the stability of the auxiliary plate 301 during adjustment and movement. When multiple positioning grooves 304 are equally spaced on the adsorption plate 303, and each positioning groove is equipped with a suction cup 305, when the auxiliary plate 301 is attached to the side of the die-cast part 4, the corresponding suction cup 305 can be adsorbed onto the die-cast part 4. The connecting pipe 311 moves up and down within the sleeve pipe 312, and the sleeve pipe 312 is threadedly connected to the center position within the positioning groove 304, preventing the suction cup 305 from detaching from the positioning groove. The function of the slot 304 is that one end of the branch pipe 307 has a single interface, while the other end has multiple interfaces. The single interface is connected to an external fan, while the multiple interfaces are connected to a sleeve pipe 312 to achieve the effects of suction and blowing. When suction is applied, the suction cup 305 is firmly attached to the side of the die-casting part, while when blowing is applied, the suction cup 305 is detached from the side of the die-casting part. The tension spring 310 pushes the suction cup 305 upward, making the suction cup 305 higher than the adsorption plate 303, so that it can better contact the side of the die-casting part 4 for adsorption.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
