Description

Technical Field

[0001] This invention relates to the field of clamping technology, and more particularly to a universal clamping platform. Background Technology

[0002] Clamping plates are small machine tool parts used in vertical machining centers, horizontal machining centers, turret milling machines, and CNC lathes. They are mostly used in large components such as transmission systems and tool magazines. Clamping plates used on machine tools are generally long and strip-shaped, especially the clamping plates of vertical machining centers and horizontal machining centers. They need to go through four main processes: rough milling of flat surfaces, rough milling of inclined surfaces, drilling, and countersinking. Currently, clamping plates are processed one piece at a time, and each piece needs to be loaded and unloaded once. A vise or simple tooling is used to clamp the workpiece.

[0003] Chinese utility model patent "A CNC equipment fixture for hole machining", publication number CN208628972U, describes a fixture comprising a tooling plate, a pneumatic clamping assembly, and a product fixing assembly. The tooling plate includes a tooling base plate, a cylinder mounting plate, and a product fixing assembly mounting plate. The pneumatic clamping assembly includes a cylinder and a push plate. The cylinder is fixed to the side of the cylinder mounting plate with screws, and the push plate is fixed to the end of the cylinder's piston rod with screws. The product fixing assembly includes a fixture fixing plate, a product positioning plate, and a pressure block. The product fixing assembly is fitted onto the side of the product fixing assembly mounting plate, and the fixture fixing plate, product positioning plate, and pressure block are connected by screws.

[0004] Existing clamping platforms are prone to crushing and damaging products when clamping and positioning them. This causes the product's position to shift during subsequent processing, resulting in a decrease in processing quality and accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a universal clamping platform to address the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A universal clamping platform includes a rotating disk and a fixed disk mounted above the rotating disk. The rotating disk has multiple positioning stations arranged in a ring at equal intervals. Positioning fixtures are installed at the positioning stations. The fixed disk is provided with a first adjusting drive component that cooperates with the positioning fixtures. The positioning fixture includes guide rods and adjusting rods arranged in parallel and spaced apart. Fixed seats are installed at both ends of the guide rods and adjusting rods. An adjusting seat and a support seat are slidably installed between the two fixed seats. One of the fixed seats is provided with a first elastic locking block that contacts the edge of the product. The adjusting seat is provided with a second elastic locking block that contacts the edge of the product. The support seat is provided with a support column that provides elastic support for the product. The guide rods and adjusting rods are also slidably mounted with a drive seat. Rotating arm assemblies are respectively installed at both ends of the drive seat. The rotating arm assembly includes a first rotating arm and a second rotating arm that is rotatably connected to the first rotating arm with damping. The second rotating arm is provided with a third elastic locking block that contacts the edge of the product.

[0008] Furthermore: the drive seat and the adjustment seat are respectively formed with a guide hole that mates coaxially with the guide rod and an adjustment hole that mates coaxially with the adjustment rod. The top of the two fixed seats is respectively formed with multiple first mounting holes, and the adjustment seat is formed with multiple second mounting holes. The first elastic locking block can adjust its installation position through the first mounting hole, and the second elastic locking block can adjust its installation position through the second mounting hole.

[0009] Furthermore, the rotating arm assembly also includes a drive arm mounted on the drive seat, a first damping hinge structure is provided between the drive arm and the first rotating arm, and a second damping hinge structure is provided between the first rotating arm and the second rotating arm.

[0010] Furthermore: There are two adjusting rods, arranged coaxially, and each adjusting rod is an adjusting screw. One adjusting rod is installed between one of the fixed seats and the drive seat, and the other adjusting rod is installed between the other fixed seat and the adjusting seat. The drive seat slides with the adjusting rod through the adjusting hole, and the adjusting seat slides with the adjusting rod through the adjusting hole. The bottom of the support seat has a sliding groove that slides with the adjusting rod and a guide groove that slides with the guide rod. The support seat is also equipped with an anti-slip rod that is inserted laterally into the guide groove and loosely and tightly fitted with the guide rod.

[0011] Furthermore: a first rotating chuck is installed on the other side of the adjusting seat, and a second rotating chuck is installed on another fixed seat opposite to the first rotating chuck. The opposing surfaces of the first rotating chuck and the second rotating chuck are both formed with positioning surfaces that contact the product.

[0012] Furthermore: the positioning surface is a triangular groove that clamps the product or a rough surface that rubs against the product.

[0013] Furthermore, an annular disk is also provided around the rotating disk, and the annular disk is coaxially aligned with the rotating disk. A second adjusting drive component is installed on the annular disk, which is coaxially engaged with the first adjusting drive component. The adjusting rod of the positioning fixture on the rotating disk is coaxially aligned with the first adjusting drive component and the second adjusting drive component, respectively.

[0014] Furthermore: the first and second adjustment drive components respectively include adjustment telescopic cylinders mounted on the fixed disk and the annular disk, the drive end of the adjustment telescopic cylinder is equipped with an adjustment motor, and the drive end of the adjustment motor is equipped with a coupling that can be connected to the adjustment rod for transmission.

[0015] Furthermore, the fixture platform is also equipped with a transfer robot located around the annular disk. The transfer robot includes a multi-axis robot and a transfer fixture installed on the drive end of the multi-axis robot. The transfer fixture includes a transfer bracket, which has multiple adjustable elongated holes and a suction cup that can be adjusted in position through the adjustable elongated holes.

[0016] Furthermore, the transfer bracket is also equipped with lifting mechanisms at both ends, which can lift the product for suction cup adsorption. The lifting mechanism includes a longitudinally arranged lifting cylinder, a lifting clamp is installed at the drive end of the lifting cylinder, a longitudinally swinging swing arm is installed at the top of the lifting clamp, and the transfer bracket is provided with a fixing plate. The fixing plate has a transverse long groove for the swing arm to move when it swings.

[0017] The beneficial effects of this invention are as follows: The product to be positioned is placed on the positioning fixture at the positioning station, and the adjusting seat and support seat of the guide rod and adjusting rod are slidably mounted in the moving position. The support column mounted on the support seat provides elastic support to the bottom of the product. The front and rear ends of the product are positioned by the first elastic locking block of the fixed seat and the second elastic locking block of the adjusting seat. The two sides of the product are elastically positioned by the swing of the rotating arm assembly, so that the third elastic locking block mounted on the second rotating arm abuts against the two sides of the product. Under elastic positioning, the product is not easy to move and will not be damaged, ensuring processing quality. In addition, since the positions of the second elastic locking block and the third elastic locking block can be changed, products of different sizes can be positioned and locked, further improving practicality.

[0039] The present invention will now be described in detail with reference to the accompanying drawings.

[0040] like Figure 1-5As shown, a general-purpose clamping platform includes a rotating disk 1 and a fixed disk 11 mounted above the rotating disk 1. The rotating disk 1 has a drive hole and rotates under the drive of a motor. The fixed disk 11 is fixedly mounted above the rotating disk 1 by a bracket.

[0041] The rotating disk 1 has multiple positioning stations 12 arranged in a ring at equal intervals. Positioning stations 12 are equipped with positioning fixtures 2. The fixed disk 11 is provided with a first adjusting drive component 14 that cooperates with the positioning fixtures 2. The positioning fixture 2 includes guide rods 21 and adjusting rods 22 arranged in parallel at intervals. Fixed seats 23 are installed at both ends of the guide rods 21 and adjusting rods 22. Adjusting seat 24 and support seat 4 are slidably installed between the two fixed seats 23. One of the fixed seats 23 is provided with a first elastic locking block 25 that contacts the edge of the product. The adjusting seat 24 is provided with a second elastic locking block 26 that contacts the edge of the product. The support seat 4 is provided with a support column 40 that provides elastic support for the product. The guide rods 21 and adjusting rods 22 are also slidably installed with drive seats 31. Rotating arm assemblies 3 are respectively installed at both ends of the drive seats 31. The rotating arm assembly 3 includes a first rotating arm 33 and a second rotating arm 34 that is rotatably connected to the first rotating arm 33 with damping. The second rotating arm 34 is provided with a third elastic locking block 37 that contacts the edge of the product.

[0042] The product to be positioned is placed on the positioning fixture 2 at the positioning station 12. It is slidably mounted on the adjusting seat 24 and the support seat 4 of the guide rod 21 and the adjusting rod 22. The support column 40 mounted on the support seat 4 provides elastic support to the bottom of the product. The front and rear ends of the product are positioned by the first elastic locking block 25 of the fixed seat 23 and the second elastic locking block 26 of the adjusting seat 24. The sides of the product are elastically positioned by the swing of the rotating arm assembly 3, which causes the third elastic locking block 37 mounted on the second rotating arm 34 to abut against the sides of the product. Under elastic positioning, the product is not easy to move and will not be damaged, ensuring processing quality. In addition, since the positions of the second elastic locking block 26 and the third elastic locking block 37 can be changed, products of different sizes can be positioned and locked, further improving practicality.

[0043] Preferably, the first elastic locking block 25, the second elastic locking block 26, and the third elastic locking block 37 have the same structure, each including a bottom fixing post and an elastic rubber installed on the top of the bottom fixing post.

[0044] In one embodiment, when the product is a rigid block, the first elastic locking block 25, the second elastic locking block 26, and the third elastic locking block 37 can be replaced with bolts to lock and fix the product. In this embodiment, the product is positioned as a rigid locking block, and the product itself has sufficiently high hardness, so the bolts will not damage the product when locking it.

[0045] The drive seat 31 and the adjusting seat 24 are respectively formed with a guide hole 27 that mates coaxially with the guide rod 21 and an adjusting hole 28 that mates coaxially with the adjusting rod 22. The drive seat 31 and the adjusting seat 24 move along the length direction of the guide rod 21 and the adjusting rod 22 through the guide hole 27 and the adjusting hole 28, and their positions are adjusted according to the size of the product. The tops of the two fixed seats 23 are respectively formed with multiple first mounting holes 41, and the adjusting seat 24 is formed with multiple second mounting holes 42. The first elastic locking block 25 can be adjusted in its installation position through the first mounting hole 41, and the second elastic locking block 26 can be adjusted in its installation position through the second mounting hole 42. Depending on the shape of the product, one or more first elastic locking blocks 25 can be installed in the first mounting hole 41, and one or more second elastic locking blocks 26 can be installed in the second mounting hole 42, which can be used for edge positioning and locking of irregularly shaped products.

[0046] Specifically, the rotating arm assembly 3 also includes a driving arm 32 mounted on the driving seat 31. A first damping hinge structure 35 is provided between the driving arm 32 and the first rotating arm 33, and a second damping hinge structure 36 is provided between the first rotating arm 33 and the second rotating arm 34. This allows the first rotating arm 33 to swing around the driving arm 32 and the second rotating arm 34 to swing around the first rotating arm 33, with damping. After swinging to the desired position, the damping hinge structure restricts the swing to maintain the specified state, allowing the third elastic locking block 37 mounted on the second rotating arm 34 to maintain its current state against both sides of the product and position both sides of the product.

[0047] Preferably, there are two adjusting rods 22, which are arranged coaxially. Each adjusting rod 22 is an adjusting screw. One adjusting rod 22 is installed between one of the fixed seats 23 and the drive seat 31, and the other adjusting rod 22 is installed between another fixed seat 23 and the adjusting seat 24. The drive seat 31 is slidably engaged with the adjusting rod 22 through the adjusting hole 28, and the adjusting seat 24 is slidably engaged with the adjusting rod 22 through the adjusting hole 28. Both the adjusting seat 24 and the drive seat 31 have threaded sleeves installed in their adjusting holes 28, so that the adjusting seat 24 is slidably engaged with the adjusting rod 22 through the threaded sleeves, and the drive seat 31 is slidably engaged with the adjusting rod 22 through the threaded sleeves. That is, when the adjusting rod 22 rotates, the adjusting seat 24 or the drive seat 31 can slide along the length of the guide rod 21 to adjust the position, which is convenient for positioning products of different sizes and adapting to different products.

[0048] Preferably, the bottom of the support base 4 is provided with a sliding groove 43 that slides with the adjusting rod 22 and a guide groove 44 that slides with the guide rod 21. The support base 4 is also equipped with an anti-slip rod 45 that is laterally inserted into the guide groove 44 and loosely and tightly fitted with the guide rod 21. In this embodiment, the movable support base 4 can have multiple support columns 40 with different heights, which facilitates the support of products with irregular bottom surfaces, and the bottom surface of the product will not shift or tilt to the left or right.

[0049] Furthermore, a first rotating chuck 46 is installed on the other side of the adjusting seat 24, and a second rotating chuck 47 is installed on another fixed seat 23, which is arranged opposite to the first rotating chuck 46. The opposing surfaces of the first rotating chuck 46 and the second rotating chuck 47 are both formed with positioning surfaces 48 that contact the product. The positioning fixture 2 of this solution can also use the adjusting seat 24 and the fixed seat 23 to make the first chuck and the second chuck close to each other, and clamp another product face to achieve the effect of one fixture for multiple uses.

[0050] Preferably, the positioning surface 48 is a triangular groove for clamping the product. The first rotating chuck 46 and the second rotating chuck 47 can clamp the sheet-like plate, the triangular groove can position the product, and the first rotating chuck 46 and the second rotating chuck 47 can rotate, so the product can rotate at an angle. During processing, it can be facing up or facing down.

[0051] Preferably, the positioning surface 48 is a rough surface that comes into frictional contact with the product. The two sides of the product are adhered to the rough surface, which has a large static friction force. The product will not fall off the first chuck and the second chuck, thus improving the clamping stability.

[0052] An annular disk 13 is also provided around the rotating disk 1. The annular disk 13 is coaxially aligned with the rotating disk 1. A second adjusting drive component 15 is installed on the annular disk 13, which is coaxially engaged with the first adjusting drive component 14. The adjusting rod 22 of the positioning clamp 2 on the rotating disk 1 is coaxially aligned with both the first adjusting drive component 14 and the second adjusting drive component 15. The first adjusting drive component 14 and the second adjusting drive component 15 each include an adjusting telescopic cylinder 16 installed on the fixed disk 11 and the annular disk 13, respectively. An adjusting motor 17 is installed at the drive end of the adjusting telescopic cylinder 16, and a coupling 18 that can be transmitted with the adjusting rod 22 is installed at the drive end of the adjusting motor 17.

[0053] In this embodiment, when the rotating disk 1 rotates to the unloading position, the positioning fixture 2 needs to be opened to allow the product to be placed in. That is, the adjusting rod 22 of the positioning fixture 2 is coaxially aligned with the first adjusting drive 14 and the second adjusting drive 15 respectively. The adjusting telescopic cylinder 16 extends, so that the coupling 18 installed on the adjusting motor 17 is connected to the adjusting rod 22 for transmission. The adjusting motor 17 reverses, and the adjusting seat 24 moves outward to form a larger space for the product to be placed into the positioning fixture 2.

[0054] When the rotating disk 1 rotates to the placement station, the positioning fixture 2 needs to close to clamp the product. At this time, the adjusting rod 22 of the positioning fixture 2 is coaxially aligned with the first adjusting drive 14 and the second adjusting drive 15 respectively. The adjusting telescopic cylinder 16 extends, so that the coupling 18 installed on the adjusting motor 17 is connected to the adjusting rod 22. The adjusting motor 17 rotates forward, and the adjusting seat 24 moves inward, and the product is positioned by the first elastic locking block 25 and the second elastic locking block 26.

[0055] Furthermore, the fixture platform is also equipped with a transfer robot 5 located around the annular disk 13. The transfer robot 5 includes a multi-axis robot 50 and a transfer fixture 51 installed on the drive end of the multi-axis robot 50. The transfer fixture 51 includes a transfer bracket 52, which has multiple adjustable elongated holes 53 and suction cup components 54 that can be adjusted in position through the adjustable elongated holes 53. The transfer robot 5 uses the suction cup components 54 installed in the adjustable elongated holes 53 to adsorb products for loading and unloading. Since the adjustable elongated holes 53 can adjust the position of the suction cup components 54, the position of the suction cup components 54 can be finely adjusted according to the position of the adsorption surface of the product, so that the suction cup components 54 can contact the product and achieve adsorption.

[0056] Furthermore, the transfer bracket 52 is equipped with lifting mechanisms at both ends to lift the product for adsorption by the suction cup component 54. The lifting mechanism includes a longitudinally arranged lifting cylinder 55, a lifting clamp 56 is installed at the drive end of the lifting cylinder 55, and a longitudinally swinging swing arm 57 is installed at the top of the lifting clamp 56. The transfer bracket 52 is provided with a fixed plate 58, and the fixed plate 58 has a transverse long groove 59 for the swing arm 57 to move when swinging. Before adsorbing the product, the lifting cylinder 55 works and retracts, causing the lifting clamp 56 to rise. One end of the swing arm 57 swings around the transverse long groove 59 of the fixed plate 58, so that the lifting clamp 56 can rise and fall to lift the product for adsorption by the suction cup component 54, while preventing the product from falling off the suction cup component 54.

[0057] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0058] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
