DETAILED DESCRIPTION

[0028] 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.

[0029] Embodiment: A positioning and pressing station for an assembly production line, such as Figure 1-Figure 4 As shown, it includes a workbench 1 and a driving shaft 2 arranged at the upper end of the workbench 1 and controlled by an internal stepper motor of the workbench 1 to rotate ninety degrees each time. A turntable 3 rotating synchronously with the driving shaft 2 is installed on the top of the driving shaft 2. Four groups of pressing stations 4 are arranged at an angle of ninety degrees on the top of the turntable 3. Four groups of working holes 5 penetrating the turntable 3 from top to bottom are opened on the turntable 3 corresponding to each group of pressing stations 4. A force-bearing platform 6 is installed on the top of the workbench 1 at a position corresponding to the moving trajectory of the working hole 5, and the force-bearing platform 6 vertically corresponds to the position of the lower pressure head.

[0030] The press-fitting station 4 includes a top plate 41, a placement groove 43 corresponding to the vertical position of the working hole 5 is opened in the middle position of the top plate 41, a limit step 44 is arranged on the inner side of the placement groove 43, and connecting columns 42 are vertically arranged at the four corners of the lower end of the top plate 41. The top of the connecting column 42 passes through the top plate 41 and extends to the upper end of the top plate 41 and is fixed by a fixing component. The top of the connecting column 42 is located on one side of the lower end of the top plate 41 and is connected to an upper limit clamp 47 that contacts with the bottom surface of the top plate 41 and forms a support. The lower end of the connecting column 42 passes through the turntable 3 and extends to the bottom of the turntable 3. The connecting column 42 is connected to a lower limit clamp 46 at the position below the turntable 3. A spring 45 is sleeved on the connecting column 42. The top of the spring 45 is fixed to the upper limit clamp 47, and the bottom of the spring 45 is fixed to the upper surface of the turntable 3.

[0031] When in use, the accessories to be processed are placed in the placement grooves 43 of each group of pressing stations 4 in turn, and the accessories are supported and fixed by setting limit steps 44. The top plate 41 is detachably connected and can be replaced for different accessories. The turntable 3 rotates according to the ninety-degree angle rule. When the pressing station 4 rotates to the position corresponding to the force-bearing platform 6, the pressing mechanism moves downward to test the pressure to press the accessories. The acceptance of the accessories drives the top plate 41 to move downward until the bottom of the accessories contacts the force-bearing platform 6. At this time, the pressing mechanism continues to apply pressure downward to complete the pressing. After pressing, the pressing mechanism moves upward and returns to the initial position. The top plate 41 moves up and returns to the initial position under the elastic force of the spring 45. By setting the pressing station 4, the pressure applied by the pressing mechanism during the pressing process will not act on the turntable 3, and the force of the entire pressing process is borne by the force-bearing platform 6, thereby protecting the turntable 3 to the greatest extent and preventing the turntable 3 from being deformed by the force and affecting the processing accuracy of the equipment.

[0032] Embodiment 2: Based on embodiment 1, Figure 4 As shown, the top plate 41 and the connecting column 42 are fixed by threaded fixing with a fixing nut 7 .

[0033] The top plate 41 can be disassembled or replaced by removing the fixing nut 7, thereby realizing the processing of multiple types of accessories.

[0034] Embodiment 3: Based on embodiment 1, Figure 5 As shown, the top plate 41 and the connecting column 42 are fixed by means of a locking pin 8. The locking pin 8 is a conical structure with a groove in the middle, and an annular mounting groove is provided at the lower end of the cone. The top of the locking pin 8 is located on both sides of the groove and is connected to a pressing rod 9.

[0035] When installing the top plate 41, align the holes at the four corners of the top plate 41 with the positions of the four groups of locking pins 8, and squeeze the top plate 41 downward so that the holes of the top plate 41 squeeze the locking pins 8. The locking pins 8 are squeezed to displace the position of the middle groove. After the locking pins 8 pass through the upper end holes of the top plate 41, the holes and the annular mounting grooves are stuck together, and the locking pins 8 expand to both sides to restore their initial shape and fix the top plate 41 through the bottom of the conical structure. When the top plate 41 needs to be disassembled, press the two groups of pressing rods 9 to drive the two sides of the locking pins 8 to move closer to the position of the middle groove. After the locking pins 8 are close together, the top plate 41 can be removed upwards.

[0036] By providing the locking pin 8, the top plate 41 can be disassembled or replaced, thereby realizing the processing of multiple types of accessories.

[0037] Embodiment 4: Based on embodiment 1, Figure 6 to Figure 7 As shown, a freely rotatable rotating pressure plate 10 is installed on the top of the upper limit clamp 47, and a positioning frame 11 with an opening toward the middle position of the top plate 41 is provided on the top of the four groups of upper limit clamps 47. The four groups of positioning frames 11 form a rectangular plane space, a shift block 12 is installed on the upper end of the rotating pressure plate 10, and a rubber layer 13 is installed on the bottom of the rotating pressure plate 10.

[0038] When in use, the top plate 41 is placed on the four sets of upper limit clamps 47 and limited by the positioning frame 11, and the four sets of rotating pressure plates 10 are rotated to the position above the corners of the top plate 41 to fix the corners of the top plate 41. The shift block 12 is set to better operate the rotating pressure plate 10, and the rubber layer 13 can increase the friction between the lower end surface of the rotating pressure plate 10 and the top of the top plate 41.

[0039] By providing the rotating pressing plate 10 and the positioning frame 11 , the top plate 41 can be disassembled, assembled or replaced, thereby realizing the processing of multiple types of accessories.
