[0001] The utility model relates to the technical field of bowl pressing equipment, in particular to a turnover adjustment mechanism of a bowl pressing machine. Background Art

[0002] A bowl press is an auxiliary machine that assembles the upper and lower bowls of a bicycle frame onto the frame. The bowl pressing work of the head tube, bottom bracket tube and front fork tube in the frame cannot be done without a bowl press.

[0003] However, in the traditional bowl pressing work, the frame is first installed on the bowl press, and then the upper bowl assembly (or lower bowl assembly) is pressed into the pipe end of the corresponding pipe fitting on the frame through the bowl press. Then, the frame needs to be removed and turned 180 degrees before being reinstalled on the bowl press, and the lower bowl assembly (or upper bowl assembly) is pressed into the other pipe end of the corresponding pipe fitting on the frame through the bowl press. It can be seen that two disassembly and assembly and one turning over are required for bowl pressing of the same pipe fitting, which makes the bowl pressing work steps more cumbersome and complicated, resulting in low efficiency of production work, and the frame generally has a certain weight, which is time-consuming and labor-intensive to turn over, resulting in the bowl pressing work not being simple and efficient enough.

DETAILED DESCRIPTION

[0025] 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.

[0026] The utility model provides an embodiment of a flip adjustment mechanism for a bowl press: Figures 1 to 3 As shown, it includes a portal frame 1 and a workbench 12, the portal frame 1 is fixedly installed on the workbench 12, a cylinder 9 is arranged above the portal frame 1, the telescopic end of the cylinder 9 is located inside the portal frame 1 and a pressing bowl punch 10 is installed, a threaded shaft 11 is fixedly installed on the workbench 12, a nut is threadedly installed on the threaded shaft 11, a guide column 2 is vertically fixedly connected inside the portal frame 1, a guide sleeve 3 is slidably connected to the outside of the guide column 2, a return spring 4 is arranged at the lower part of the guide sleeve 3, the return spring 4 is sleeved on the outside of the guide column 2, and the upper and lower ends of the return spring 4 are respectively connected to the guide sleeve 3 and the workbench 12, a flip assembly 5 is arranged on the guide sleeve 3, the guide sleeve 3 is connected to the mounting frame 6 through the flip assembly 5, and the mounting frame 6 is provided with a clamping assembly 7 for clamping the frame pipe 8;

[0027] like Figures 4 to 7As shown, the clamping assembly 7 includes a guide shaft 701 fixed on the mounting frame 6, two sliding sleeves 702 are slidably connected to the guide shaft 701, and clamping springs 704 are respectively provided between the two sliding sleeves 702 and the mounting frame 6, and clamping blocks 703 are fixed on the two sliding sleeves 702, the two clamping blocks 703 are symmetrically distributed, and the inside of the clamping blocks 703 is opened with a through stepped hole 7031, and the larger diameter section of the stepped hole 7031 is the same as the diameter of the pipe fitting 8 of the frame;

[0028] The clamping assembly 7 also includes a gear 705 rotatably mounted on the mounting frame 6, and racks 706 are meshed and connected on both sides of the gear 705. The two racks 706 are respectively slidably mounted on the mounting frame 6, and the two racks 706 are axially symmetrically distributed about the axis of the gear 705. The two sliding sleeves 702 are respectively fixed to the two racks 706.

[0029] In the initial state, the mounting frame 6 is in a vertical state, the clamping block 703 is located directly above the threaded shaft 11, and the stepped hole 7031 is coaxial with the threaded shaft 11;

[0030] When the bracket 701 is in the state of being tilted, the upper and lower clamping blocks 703 are pressed downwardly to drive the sliding sleeve 702 to slide downwardly along the guide shaft 701. During this process, the sliding sleeve 702 can drive one of the racks 706 to slide synchronously, thereby driving the gear 705 to rotate. The gear 705 further drives the other rack 706 to slide upward, thereby driving the upper sliding sleeve 702 and the clamping block 703 to slide upward. During this process, the sliding sleeve 702 will compress the clamping spring 704 until the distance between the two clamping blocks 703 is greater than the length of the bracket 8. The bracket 8 can be straightened to a vertical state, and then the pressure applied to the lower clamping block 703 can be reduced. At this time, the upper and lower clamping blocks 703 can be driven to approach each other under the action of the rebound force of the clamping spring 704 until the large diameter section of the stepped hole 7031 on the upper clamping block 703 is reached. The diameter section can be sleeved on the upper end of the pipe fitting 8, and then the bowl set that needs to be pressed into the upper end of the pipe fitting 8 is placed from the upper part into the small diameter section of the stepped hole 7031 on the upper clamping block 703, and then the cylinder 9 is started. At this time, the telescopic end of the cylinder 9 pushes the bowl pressing punch 10 to extend downward until it is inserted into the stepped hole 7031 from the upper part, and then the bowl pressing punch 10 continues to move downward, which can drive the mounting frame 6 and the guide sleeve 3 to slide downward along the guide column 2 and compress the reset spring 4. In this process The stepped hole 7031 on the lower clamping block 703 and the pipe fitting 8 will be sleeved on the threaded shaft 11 until the lower clamping block 703 contacts the nut on the threaded shaft 11. The bowl pressing punch 10 continues to press downward to press the bowl assembly into the upper end of the pipe fitting 8. Then the cylinder 9 drives the bowl pressing punch 10 upward. In this process, the guide sleeve 3, the mounting frame 6 and the pipe fitting 8 can be pushed back to their original positions under the action of the rebound force of the reset spring 4, thereby completing the bowl pressing work on the upper end of the pipe fitting 8.

[0031] like Figures 7 and 8 As shown, the flip assembly 5 includes a fixed sleeve 501 and a flip shaft 502, the fixed sleeve 501 is fixed on the guide sleeve 3, the flip shaft 502 is fixed on the mounting frame 6, and the flip shaft 502 is rotatably connected to the fixed sleeve 501;

[0032] The flip assembly 5 also includes an automatic limiting mechanism, which includes two fixed tubes 504 arranged on the outside of the fixed sleeve 501 and a groove 503 opened on the outer circular surface of the flip shaft 502. The two fixed tubes 504 are symmetrically distributed, and the inside of the fixed tube 504 is slidably connected with an insertion rod 506. One end of the insertion rod 506 is inserted into the groove 503 by passing through the outer wall of the fixed sleeve 501, and the other end is provided with a limiting spring 505. The end of the fixed tube 504 inserted into the groove 503 is in the shape of an isosceles triangle or an isosceles trapezoid. The groove 503 is adapted to the fixed tube 504, and the two grooves 503 are symmetrically distributed.

[0033] After the pressing bowl on the upper end of the pipe fitting 8 is completed, the pipe fitting 8 is turned over. During this process, the pipe fitting 8 will drive the mounting frame 6 and the turning shaft 502 to rotate around the axis of the turning shaft 502 through the clamping assembly 7. At the same time, the insertion rod 506 can be pushed outward under the action of the inclined surface of the groove 503 and the inclined surface of the end of the insertion rod 506, so that the end of the insertion rod 506 is disengaged from the groove 503, and the limit spring 505 is compressed at the same time, and then the pipe fitting 8 is turned over 180 degrees, and then under the rebound force of the limit spring 505, the pipe fitting 8 is turned over again. One end of the insertion rod 506 can be reinserted into the other groove 503. At this time, the turning shaft 502 and the fixing sleeve 501 can be fixed to a certain extent under the cooperation of the insertion rod 506 and the groove 503 to prevent deflection between the two. Then, the bowl set that needs to be pressed into the upper end of the pipe fitting 8 is placed from the top into the small diameter section of the stepped hole 7031 on the upper clamp 703, and the cylinder 9 is started to repeat the above-mentioned pressing action. After the pressing is completed, the pipe fitting 8 is removed, and the pressing work of the bowl sets at both ends of the pipe fitting 8 can be completed.
