Description

Technical Field

[0001] This utility model relates to the field of aluminum radiator manufacturing technology, and specifically to a multi-station gripper assembly for aluminum radiators. Background Technology

[0002] In the manufacturing process of aluminum radiators, anodizing is a key process to improve their corrosion resistance, wear resistance, and heat dissipation performance. However, in existing technologies, aluminum radiators need to be fixed in a fixture to complete the electrolytic reaction before anodizing.

[0003] like Figure 1-2 As shown, the existing fixture has a planar frame structure, with at least one side having a matrix of claw assemblies for suspending aluminum radiators. To accommodate aluminum radiators of different shapes, the claw assemblies use a symmetrically placed elastic claw structure, utilizing the outward elastic force of the claws to suspend the aluminum radiators. Since the claw assemblies need to be pressed to bring the heads of the elastic claws closer together before the aluminum radiators can be installed, the current method of manual loading is not only labor-intensive and time-consuming, but also inefficient and costly. Utility Model Content

[0006] The extrusion mechanism includes a rotating shaft arranged along the direction of multiple gripper cylinders, multiple V-shaped connecting rods rotatably mounted on the rotating shaft and offset from the gripper cylinders, a connecting shaft for connecting the upper ends of the multiple V-shaped connecting rods, a pressure shaft for connecting the lower ends of the multiple V-shaped connecting rods, and at least one extrusion cylinder with a hinge on the side of the fixed seat and its drive end connected to the connecting shaft; the distance from the gripper cylinder to the fixed seat is less than the distance from the pressure shaft to the fixed seat.

[0007] Preferably, both ends of the rotating shaft are connected to the bottom of the fixed base via support columns, and bearings are provided at the connection points.

[0008] Preferably, the telescopic mechanism includes a movable seat placed parallel to the fixed seat, a telescopic cylinder disposed on the fixed seat for driving the movable seat closer to or away from the fixed seat, and a plurality of guide posts disposed on the movable seat and passing through the fixed seat; the plurality of gripper cylinders are disposed at the bottom of the movable seat.

[0010] Preferably, a self-lubricating bushing is provided at the connection between the guide post and the bottom of the fixed seat.

[0011] Preferably, the top two sides of the fixing base are provided with hollowed-out portions above the guide posts.

[0012] Preferably, the top center of the fixed base is provided with a connecting plate for connection with the robotic arm.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Appendix Figure 3 The multi-station gripper assembly for aluminum radiators described in this utility model includes a fixed base 3, a telescopic mechanism 4 disposed on the fixed base 3, five gripper cylinders 5 arranged at linear intervals on the telescopic mechanism 4 for simultaneously gripping multiple aluminum radiators 2, and a pressing mechanism 6 disposed on the fixed base 3 and located on both sides of the five gripper cylinders 5 for pressing the gripper assembly 11 to bring the heads of the elastic grippers 12 closer to each other.

[0024] During material handling: five aluminum radiators 2 can be directly gripped by five gripper cylinders 5;

[0025] During loading: First, the pressing mechanism 6 presses the claw assembly 11 on the fixture 1, causing the heads of the elastic claws 12 to move closer to each other. Then, the telescopic mechanism 4 drives the five gripper cylinders 5 to extend, so that the heads of the elastic claws 12 are located inside the aluminum radiator 2. Then, the pressing mechanism 6 releases the claw assembly 11, and the aluminum radiator 2 is suspended by the outward elasticity of the elastic claws 12. Finally, the five gripper cylinders 5 release the five aluminum radiators 2 respectively, and at the same time, the telescopic mechanism 4 drives the five gripper cylinders 5 to retract to the initial position, completing the loading operation.

[0026] Furthermore, such as Figure 4-5 As shown, the extrusion mechanism 6 includes a rotating shaft 61 arranged along the direction of the five gripper cylinders 5, four V-shaped connecting rods 62 rotatably mounted on the rotating shaft 61 and offset from the gripper cylinders 5, a connecting shaft 63 for connecting the upper ends of the four V-shaped connecting rods 62, a pressure shaft 64 for connecting the lower ends of the four V-shaped connecting rods 62, and two extrusion cylinders 65 with hinges on the side of the fixed base 3 and whose driving ends are simultaneously connected to the connecting shaft 63; the distance from the gripper cylinders 5 to the fixed base 3 is less than the distance from the pressure shaft 64 to the fixed base 3;

[0027] During operation: Two extrusion cylinders 65 simultaneously drive the connecting shaft 63 to lower the upper ends of the four V-shaped connecting rods 62. Since the V-shaped connecting rods 62 are rotatably mounted on the rotating shaft 61, the lower ends of the four V-shaped connecting rods 62 drive the pressure shaft 64 to press the claw assembly 11, causing the heads of the elastic claws 12 to move closer to each other, which facilitates the loading operation.

[0028] Furthermore, such as Figure 4-5 As shown, the two ends of the rotating shaft 61 are connected to the bottom of the fixed base 3 through the support column 66, so that the rotating shaft 61 is suspended on both sides of the gripper cylinder 5, and there is enough space to install the extrusion cylinder 65.

[0029] Furthermore, bearings are provided at both ends of the shaft 61 where it connects to the support column 66, which can reduce wear on the shaft 61 and improve its service life.

[0030] Further, as shown in Figure 3 and Figure 5 shown, the telescopic mechanism 4 includes a movable seat 41 placed parallel to the fixed seat 3, a telescopic cylinder 42 arranged on the fixed seat 3 for driving the movable seat 41 to approach or move away from the fixed seat 3, and four guide columns 43 arranged on the movable seat 41 and passing through the fixed seat 3; five of the jaw cylinders 5 are arranged at the bottom of the movable seat 41; during operation: the telescopic cylinder 42 drives the movable seat 41 to approach or move away from the fixed seat 3, and the guide columns 43 play a guiding role, making the movement of the movable seat 41 smoother.

[0031] Further, as shown in Figure 4-5 shown, the fixed seat 3 is of a hollow structure with a cross-section in the shape of a rectangle with a hole in the middle; the telescopic cylinder 42 is arranged inside the fixed seat 3, and its driving end passes through the bottom of the fixed seat 3 and is connected to the movable seat 41; the guide columns 43 all pass through the bottom of the fixed seat 3, making the overall structure simpler, more compact and lighter.

[0032] Further, as shown in Figure 4 shown, self-lubricating bushings 44 are arranged at the joints of the guide columns 43 and the bottom of the fixed seat 3, which can reduce the wear of the guide columns 43 and improve the service life.

[0033] Further, as shown in Figure 5 shown, hollowed-out parts 31 are arranged on both sides of the top of the fixed seat 3 above the guide columns 43, which can reduce the thickness of the fixed seat 3 without affecting the operation of the guide columns 43, and can also reduce the weight, facilitating lightweighting.

[0034] Further, as shown in Figure 5 shown, a connecting plate 7 is arranged at the center of the top of the fixed seat 3, which is convenient for connecting with the robotic arm.

[0035] The above are only specific application examples of the present invention, which do not constitute any limitation to the protection scope of the present invention. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the protection of the rights of the present invention.
