[0015] The beneficial effects of the present invention are: 1. The present invention can install the parts to be processed on the carrier by providing a rotating table mechanism, a pressure mechanism and a lifting mechanism. Based on the movement of the rotating table mechanism, the carrier is driven to move to the processing position, the lifting mechanism lifts the carrier upward into place, and the pressure mechanism performs the pressure operation; since multiple press bodies are provided on the rotation path of the rotating table mechanism, the pressure mechanisms of the multiple press bodies can be different, which can realize multiple pressure operations on the parts to be processed, saving processes and improving processing efficiency.

[0016] 2. The present invention provides a lifting mechanism, which can achieve reliable positioning by inserting the positioning plug into the slot of the positioning seat during lifting, and then reliably lift the bottom surface of the positioning seat through the push plate, thereby pushing the carrier and the carrier to the processing position. This method can effectively avoid the processing misalignment caused by the rotation angle deviation of the turntable body, thereby improving the processing accuracy.

[0017] 3. The present invention can conveniently disassemble and assemble the carrier on the positioning column of the carrier by providing a positioning groove, a positioning column and a piston rod; during the lifting process, the top end of the piston rod enters the positioning column, pushing the gas in the positioning column upward, thereby expanding the elastic rubber sleeve and filling the upper groove, thereby improving the firmness of the connection between the positioning column and the positioning groove and ensuring the reliability of the processing.

[0018] 4. The present invention provides structures such as a clamping assembly and a strip plate, so that the handle can be lifted first, the clamping assembly can be used to fix the workpiece to be processed, and the fixed position can be determined by the scale line. After the fixation is completed, based on the spring rebound force of the handle, the elastic protrusion is stuck in the strip groove on the top of the positioning wheel, avoiding the rotation of the positioning wheel as much as possible, thereby ensuring the stability of the positioning splint; the handle can also be used as a handle when transporting the carrier, thereby improving practicality.

[0019] 5. The present invention sets a positioning ball and a sensor detection component, which can use the sensor detection component to detect whether the structure has moved into place, so as to control the hydraulic cylinder to lift it through a control module. When the structure is offset, the two positioning balls will inevitably be misaligned. When the sensor detection component can detect one of the positioning balls, it indicates that the deviation is within a controllable range. Since the diameter of the positioning ball is smaller than the thickness of the positioning plug rib, the positioning plug can still smoothly enter the positioning seat during lifting; if the sensor detection component cannot detect the positioning ball, it indicates that the deviation is too large, and the structure will not perform lifting operations, thereby improving reliability.

[0020] 6. The present invention provides a cleaning mechanism, which can transport cleaning liquid into the elastic liquid bag based on the liquid supply device, and the elastic liquid bag stores the cleaning liquid. When the rotating table mechanism moves, the mounting rod can squeeze the roller, thereby pressing the elastic liquid bag, and pressing the cleaning liquid out to the surface of the positioning plug, thereby achieving the purpose of cleaning the positioning plug, avoiding the situation where impurities adhere to the positioning plug and causing it to be skewed when inserted into the positioning seat, thereby improving reliability.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0025] Example 1: A multi-station press, such as Figure 1-6 As shown, it includes a rotary table mechanism, the rotary table mechanism is annular in structure, and a plurality of press bodies 1 are arranged on the rotation path of the rotary table mechanism; The rotating platform mechanism comprises: The rotating platform body is provided with an annular carrier 8 distributed circumferentially; The carrier 9 is connected to the annular carrier 8 via an annular elastic connecting portion 10, and the carrier 9 and the annular carrier 8 are concentric; Carrier 7, carrier 7 is detachably mounted on carrier 9; A rotation drive assembly, the rotation drive assembly is used to drive the turntable body to rotate; The press body 1 is equipped with a pressure mechanism for performing a pressure operation and a lifting mechanism for lifting. The movement path of the carrier 7 passes between the pressure mechanism and the lifting mechanism. By setting up a turntable mechanism, a pressure mechanism and a lifting mechanism, the parts to be processed can be installed on the carrier 7. Based on the movement of the turntable mechanism, the carrier 7 is driven to move to the processing position, the lifting mechanism lifts the carrier 9 upward into place, and the pressure mechanism performs pressure operation; since multiple press bodies 1 are provided on the rotation path of the turntable mechanism, the pressure mechanisms of the multiple press bodies 1 can be different, and multiple pressure operations on the parts to be processed can be achieved, which saves processes and improves processing efficiency.

[0026] For reliable rotation; Figure 1 、 Figure 2 As shown, the rotating platform body includes: The outer annular frame 2 is mounted on a side of each annular carrier 8 away from the rotation center; The inner annular frame 4 is installed on one side of each annular carrier 8 close to the rotation center, and the outer annular frame 2 and the inner annular frame 4 form a concentric circle structure; The arc-shaped support seat 3 is a plurality of arc-shaped support seats 3 that are distributed in a circle, and the outer ring frame 2 is rotatably installed in the arc-shaped support seat 3 .

The inner annular frame 4 is provided with evenly distributed convex teeth, and the drive gear 5 is meshed with the convex teeth.

[0028] In order to facilitate lifting; Figure 3 、 Figure 4 As shown, the lifting mechanism includes: A hydraulic cylinder 15, with a push plate 23 mounted on the top of the hydraulic cylinder 15; The positioning plug 24 includes a plurality of ribs, which are arranged in a circumferential distribution, and the center where the plurality of ribs converge is raised upward; A positioning seat 22 is fixed to the bottom of the carrier 9, and a slot adapted to the positioning plug 24 is provided on the positioning seat 22; By setting up a lifting mechanism, when lifting, the positioning plug 24 can be inserted into the slot of the positioning seat 22 to achieve reliable positioning, and then the bottom surface of the positioning seat 22 can be reliably lifted by the push plate 23, so that the carrier 9 and the carrier 7 are pushed to the processing position. This method can effectively avoid the situation where the processing misalignment is caused by the rotation angle deviation of the turntable body, thereby improving the processing accuracy; For example, the main body of the turntable rotates 0.5° more than the driving gear. When lifting, the center of the multiple ribs of the positioning plug 24 bulges upward, which can well guide the positioning plug 24 upward and insert it into the slot of the positioning seat 22. During the process, the carrier 9 is corrected by the deformation cooperation of the annular elastic connecting part 10, ensuring reliable processing.

[0029] In order to facilitate the installation of the carrier 7; Figure 4 、 Figure 6 As shown, a positioning column 19 is fixed on the top of the carrier 9, and a positioning groove 21 adapted to the positioning column 19 is opened at the bottom of the carrier 7. When the carrier 7 is installed on the carrier 9, the positioning column 19 is inserted into the positioning groove 21.

[0030] In order to improve the fixation effect; Figure 4 As shown, the interior of the positioning column 19 is hollow, and the bottom of the carrier 9 is provided with an opening communicating with the positioning column 19. An elastic rubber sleeve 20 is provided on the outer side of the top of the positioning column 19, and an annular gap is formed between the elastic rubber sleeve 20 and the positioning column 19. An air hole is opened on the outer side of the top of the positioning column 19, and the interior of the positioning column 19 is communicated with the annular gap through the air hole. The positioning groove 21 includes an upper groove and a lower groove. The inner diameter of the upper groove is larger than the inner diameter of the lower groove. When the positioning column 19 is inserted into the positioning groove 21, the elastic rubber sleeve 20 enters the upper groove. Side brackets are provided on both sides of the push plate 23, and a piston rod 17 is slidably connected in the side bracket. The piston rod 17 and the side bracket are connected by a piston rod spring 16. The position of the piston rod 17 is adapted to the opening of the carrier 9; By providing the positioning groove 21, the positioning column 19 and the piston rod 17, the carrier 7 can be conveniently disassembled and assembled on the positioning column 19 of the carrier 9; during the lifting process, the top end of the piston rod 17 enters the positioning column 19, pushing the gas in the positioning column 19 upward, thereby expanding the elastic rubber sleeve 20 and filling the upper groove, thereby improving the firmness of the connection between the positioning column 19 and the positioning groove 21 and ensuring the reliability of the processing.

[0031] Example 2: A multi-station press, such as Figure 3 、 Figure 5 As shown, in order to facilitate the fixing of the parts to be processed, this embodiment makes the following improvements on the basis of embodiment 1: a clamping assembly is provided on the carrier 7, and the clamping assembly includes: Mounting plates 26, two mounting plates 26 are mounted on the carrier 7; A positioning splint 29 is provided with a guide rod 30 fixed to one side of the positioning splint 29. The guide rod 30 is slidably connected to the inner wall of the mounting plate 26. A scale line is provided on the guide rod 30. The threaded column 25 has one end rotatably mounted in the positioning clamping plate 29 , and the threaded column 25 is connected to the inner wall of the mounting plate 26 via threads, and a knob 34 is fixed to the other end of the threaded column 25 .

[0032] In order to facilitate reliable fixation; Figure 5 As shown, the carrier 7 is equipped with a handle cover 27, and the handle 11 is slidably connected to the inner wall of the top of the handle cover 27. The handle 11 and the handle cover 27 are connected by a handle spring 28. A positioning wheel 31 is installed on the threaded column 25, and a plurality of strip grooves are provided on the circumferential outer wall of the positioning wheel 31; a strip plate 32 is fixed to the side of the handle 11 close to the positioning wheel 31, and the bottom surface of the strip plate 32 is provided with evenly distributed elastic protrusions 33. Based on the force of the handle spring 28, some of the elastic protrusions 33 are stuck in the strip grooves of the positioning wheel 31; By setting up structures such as the clamping assembly and the strip plate 32, the handle 11 can be lifted first, and the clamping assembly can be used to fix the workpiece to be processed. The fixed position is determined by the scale line. After the fixation is completed, based on the rebound force of the handle spring 28, the elastic protrusion 33 is stuck in the strip groove at the top of the positioning wheel 31, avoiding the rotation of the positioning wheel 31 as much as possible, thereby ensuring the stability of the positioning clamp 29; the handle 11 can also be used as a handle when transporting the carrier 7, thereby improving practicality.

[0033] Example 3: A multi-station press, such as Figure 6As shown, in order to facilitate reliable processing operations, this embodiment makes the following improvements on the basis of embodiment 1: two parallel mounting rods 18 are fixed to the bottom surface of the annular carrier 8, the middle portion of the mounting rods 18 is a continuous undulating structure, and positioning balls 35 are fixed at the crests of the undulating structure of the mounting rods 18, and the positioning balls 35 of the two mounting rods 18 are adapted to each other; A sensor detection assembly 41 is provided on one side outer wall of the press body 1. The position of the sensor detection assembly 41 is adapted to the positioning ball 35. When the annular carrier 8 moves to the processing position, the positioning balls 35 corresponding to the positions on the two mounting rods 18 are located on the same straight line as the sensor detection assembly 41. The diameter of the positioning ball 35 is smaller than the thickness of the rib of the positioning plug 24. The sensor detection component 41 is connected to a control module, and the control module is connected to the lifting mechanism and the pressure mechanism by signal; By providing the positioning balls 35 and the sensor detection assembly 41, the sensor detection assembly 41 can be used to detect whether the structure has moved into place, so as to facilitate the control of the hydraulic cylinder 15 for lifting through, for example, a control module. When the structure deviates, the two positioning balls 35 will inevitably be misaligned. When the sensor detection assembly 41 can detect one of the positioning balls 35, it indicates that the deviation is within a controllable range. Since the diameter of the positioning ball 35 is smaller than the thickness of the rib of the positioning plug 24, the positioning plug 24 can still smoothly enter the positioning seat 22 during lifting. If the sensor detection assembly 41 cannot detect the positioning ball 35, it indicates that the deviation is too large and the structure will not be lifted, thereby improving reliability. The sensor detection component 41 may be a conventional detection sensor such as an infrared sensor component, as long as it can meet the detection function, and is not limited here.

[0034] In order to facilitate cleaning and positioning the plug 24; Figure 3 、 Figure 6 As shown, a cleaning mechanism is installed on the press body 1, and the cleaning mechanism includes: Lower mounting frame 37, lower mounting frame 37 is installed on the press body 1; The upper mounting frame 12 is slidably connected to the lower mounting frame 37; The elastic bladder 13 is disposed between the upper mounting frame 12 and the lower mounting frame 37.

A nozzle 36 is provided on one side of the elastic bladder 13. The nozzle 36 is connected to the bottom of the elastic bladder 13 through a pipeline. The nozzle 36 is located obliquely above the positioning plug 24. The liquid supply device 14 is installed in the press body 1, and the output end of the liquid supply device 14 is connected to the interior of the elastic liquid bag 13 through a supply pipe; The roller 40 is mounted on the upper mounting frame 12 and is located in the movement path of the mounting rod 18; By providing a cleaning mechanism, the cleaning liquid can be supplied to the elastic liquid bag 13 based on the liquid supply device 14, and the elastic liquid bag 13 stores the cleaning liquid. When the rotating platform mechanism moves, the mounting rod 18 can squeeze the roller 40, thereby pressing the elastic liquid bag 13, and outputting the cleaning liquid to the surface of the positioning plug 24, thereby achieving the purpose of cleaning the positioning plug 24, preventing the positioning plug 24 from being skewed when inserted into the positioning seat 22 due to impurities adhering to the positioning plug 24, and improving reliability. This solution realizes the automatic output of cleaning liquid without the need for an additional power source; in addition, the traditional electronically controlled liquid spraying structure can also be adopted, which is not limited here.
