Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, specifically to a servo positioner. Background Technology

[0002] Servo positioners are essential equipment in workshops for machining, welding, and other operations. A servo positioner has a fixture for the product to be processed, which is placed on the fixture. The servo positioner rotates the fixture and the product to different positions / angles so that cutting tools, welding torches, and other components can directly face the processing area of ​​the product. A common servo positioner structure includes two fixed supports with a connecting plate between them. The connecting plate is connected to each support via a turntable assembly, which rotates under the drive of the turntable assembly.

[0003] In existing technology, the connecting plate and the turntable assembly are fixedly connected, while the fixture for the product to be processed and the connecting plate are detachably connected. When the product to be processed changes, the worker needs to replace the corresponding fixture. However, when the product to be processed is larger, the size and weight of the corresponding product fixture will also increase, and the number of connection points between the product fixture and the connecting plate will also increase accordingly. If the product fixture is replaced according to the existing structure, it will undoubtedly prolong the fixture replacement time, resulting in longer waiting times for machining and welding operations; this is obviously not conducive to accelerating the production cycle. Utility Model Content

[0004] This utility model provides a mechanism for quickly assembling and disassembling a connecting plate and a turntable assembly. The fixture for the product to be processed can be quickly assembled and disassembled simultaneously with the connecting plate, thereby achieving the purpose of quickly changing large fixtures. The main technical solution adopted is as follows: A quick-change fixture mechanism for a servo positioner includes two opposing support columns, with a fixture connecting strip connecting the two support columns. Both ends of the fixture connecting strip are connected to the two support columns via a turntable connecting assembly. The turntable connecting assembly is rotatably mounted on the support columns. The key feature is: The turntable connection assembly includes a rotating shaft, a turntable, a support block, and an overlapping block. The rotating shaft is horizontally arranged, and the turntable is vertically arranged. One end of the rotating shaft is rotatably assembled with the support column, and the other end of the rotating shaft is fixedly connected to any side of the turntable. The support block is fixed to the side of the turntable facing away from the rotating shaft. At least a portion of the overlapping block is located above and fits against the support block, and the overlapping block is detachably connected to the support block. The edge of the clamp connecting strip is fixedly connected to the overlapping block.

[0005] The fixture connecting strip is used to assemble the fixtures for the products to be processed. The fixtures can be connected to the fixture connecting strip at multiple designed points.

[0006] In the turntable connecting assembly, the rotating shaft, turntable, support block, and support column are connected as one unit. The overlapping block in the turntable connecting assembly is also connected as one unit to the fixture connecting strip. When assembling the fixture connecting strip, the support block is used to receive the overlap, thereby temporarily supporting the fixture connecting strip. Because the overlapping block and support block can be designed to be relatively small, the number of detachable connection points between them can also be designed to be relatively small, thus shortening the replacement time of the fixture connecting strip. Furthermore, the product fixture and the fixture connecting strip can maintain a relatively fixed relationship, with the product fixture being assembled and disassembled synchronously with the fixture connecting strip. Therefore, shortening the replacement time of the fixture connecting strip also indirectly shortens the product fixture replacement time on the servo positioner, thus helping to accelerate the production cycle.

[0007] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the structure of the turntable connection component 3; Figure 3 This is an exploded view of turntable connection component 3. Detailed Implementation

[0008] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0009] like Figure 1 , 2 As shown in Figure 3, a servo positioner fixture quick-change mechanism includes two opposing support columns 1, with a fixture connecting strip 2 connecting the two support columns 1. The two ends of the fixture connecting strip 2 are respectively connected to the two support columns 1 via a turntable connecting assembly 3. The turntable connecting assembly 3 is rotatably mounted on the support columns 1, and the support columns 1 are configured on a processing equipment. The processing equipment may be a milling machine, an automatic welding equipment, etc.

[0010] The clamp connecting strip 2 is equipped with clamps that connect to the products to be processed. The specifications and sizes of the clamps vary for different products, and the number and position of their connection points with the clamp connecting strip 2 also differ. If the clamps are replaced directly, the replacement time will be extended as the number of connection points increases. To avoid the time-consuming process of changing clamps, the turntable connection assembly 3 can be designed as a simple, detachable structure. One specific implementation is as follows: The turntable connecting assembly 3 includes a rotating shaft 31, a turntable 32, a support block 33, and an overlapping block 34. The rotating shaft 31 is horizontally arranged, and the turntable 32 is vertically arranged. One end of the rotating shaft 31 is rotatably assembled with the support column 1, and the other end of the rotating shaft 31 is fixedly connected to either side of the turntable 32. The support block 33 is fixed to the side of the turntable 32 facing away from the rotating shaft 31. At least a portion of the overlapping block 34 is located above and abuts the support block 33, so that the support block 33 can provide necessary temporary support for the overlapping block 34 and facilitate the assembly and disassembly of the overlapping block 34. The overlapping block 34 is detachably connected to the support block 33; the edges of both ends of the clamp connecting strip 2 are fixedly connected to the overlapping block 34.

[0011] The support block 33 and the overlapping block 34 cooperate to enable quick replacement of the clamp connecting strip 2 and the clamps attached to the clamp connecting strip 2. The overlapping block 34 and the support block 33 can be detachably connected by bolts.

[0012] The turntable connecting assembly 3 further includes a guide positioning block 35, which is fixed above the support block 33. The overlapping block 34 is provided with a guide positioning port that matches the guide positioning block 35. When the overlapping block 34 rests against the support block 33 from top to bottom, the guide positioning block 35 matches and enters the guide positioning port. The guide positioning block 35 and the guide positioning port work together to perform a guiding and positioning function.

[0013] The support block 33 is provided with two quick-change pins 36, each end of which is hinged to the support block 33. The edge of the overlapping block 34 is provided with a quick-change slot corresponding to each quick-change pin 36, the opening of which is located on the side of the overlapping block 34. The quick-change pin 36 can rotate in and out of the quick-change slot. A locking nut 37 is threaded onto the free end of each quick-change pin 36, used to tighten the support block 33 and the overlapping block 34. The quick-change pins 36 are hinged to the support block 33, and the overlapping block 34 is connected or released by quickly moving in and out of the quick-change slot, thus accelerating the assembly and disassembly of the support block 33 and the overlapping block 34.

[0014] The quick-change pin 36 is also fitted with a washer 38, which is located between the hinge end of the quick-change pin 36 and the locking nut 37. The washer 38 is used to contact and abut against the overlapping block 34 to improve the tightening effect of the locking nut 37.

[0015] A preferred structure of the overlapping block 34 is as follows: the overlapping block 34 includes an overlapping portion 341, an extension portion 342, and a connecting portion 343. The overlapping portion 341 is located above the support block 33, and its lower surface abuts against the upper surface of the support block 33. The quick-change slot and the guide positioning port are both located on the overlapping portion 341. The connecting portion 343 is located below the horizontal position of the overlapping portion 341 and is used for connecting the clamp connecting strip 2. The connecting portion 343 fixes the overlapping portion 341 and the extension portion 342 together. This structure allows the center of gravity of the clamp connecting strip 2 to be located below the overlapping portion 341, increasing the stability during connection.

[0016] The quick-change slot and the quick-change pin 36 are clearance-fitted; the guide positioning port and the guide positioning block 35 are clearance-fitted; the support block 33 is provided with a fixing screw hole, and the overlapping part 341 is provided with a strip-shaped fixing hole, and the same fixing bolt passes through the strip-shaped fixing hole and the fixing screw hole. This structure can achieve further precise positioning connection on the basis of preliminary positioning connection.

[0017] The detachable structure of the turntable connecting assembly 3 specifically refers to the detachable connection structure between the support block 33 and the overlapping block 34. Regardless of the specifications or size of the product fixture, and regardless of the number or position of its connection points with the fixture connecting strip 2, the product fixture, the fixture connecting strip 2, and the overlapping block 34 can be disassembled and assembled simultaneously. The detachable connection design between the overlapping block 34 and the support block 33 has fewer connection points and a simpler structure, which can achieve the purpose of quick disassembly and assembly.

[0018] The installation and removal of the product fixture and the fixture connecting strip 2 can be carried out in advance or later in other parts of the workshop, without having to be done on the servo positioner.

[0019] The necessary structure also includes ensuring that the rotation center lines of all the turntable connecting assemblies 3 coincide to guarantee that the multiple turntable connecting assemblies 3 can rotate synchronously. Each of the turntable connecting assemblies 3 is connected to a power device to provide power to it. The commonly used power device is a servo motor, and the output shaft of the servo motor is axially fixedly connected to the rotating shaft 31.

[0020] Beneficial effects: By adopting the solution of this utility model, the product fixture can be fixed relative to the fixture connecting strip on the positioner. The product fixture can be quickly disassembled and assembled synchronously with the fixture connecting strip, thereby shortening the time for changing the product fixture on the servo positioner and helping to speed up the production cycle.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
