When the lifting platform is adjusted to the required height, the position can be automatically locked to prevent accidental movement during the stamping process, thereby ensuring operational safety. In addition, the second spring design on the guide block and the third guide rod enables the lifting block to automatically reset after the connection is released, so as to prepare for the next operation, thereby reducing manual intervention and improving work efficiency.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] Example 1

[0043] Reference Figure 1-Figure 10 A pressure press with a gauge includes: a base 1, two uprights 2, a top seat 3, a hydraulic cylinder 4, a pressure gauge 5, two support seats 6, a hydraulic pump 7, an operating handle 9, a connecting pipe 8, an adjustment seat 10, two V-shaped blocks 11, a receiving mechanism and a placing mechanism.

[0044] The base 1 serves as the supporting foundation of the entire equipment, and two vertical poles 2 are fixedly installed on the top of the base 1. The two vertical poles 2 are arranged vertically and in parallel. A top seat 3 is fixedly connected to the top of the vertical pole 2, and a hydraulic cylinder 4 is fixedly installed through the top of the top seat 3. A pressure gauge 5 is provided on the hydraulic cylinder 4 to monitor the oil pressure. On one side of one of the vertical poles 2, two support seats 6 are fixedly installed, and a hydraulic pump 7 is provided on the support seat 6. An operating handle 9 is provided on the hydraulic pump 7 to control the start and stop of the pump. The hydraulic pump 7 is connected to the hydraulic cylinder 4 through a connecting pipe 8 to realize the transmission of hydraulic power.

[0045] The adjustment seat 10 is designed as a structure that can be adjusted and sleeved on the two uprights 2, so that the height can be adjusted according to the size and position of the parts. The adjustment seat 10 is provided with two V-shaped blocks 11, which are arranged opposite to each other and are used to carry and stabilize the parts, and are used in conjunction with the piston rod of the hydraulic cylinder 4 to perform stamping and disassembly operations on the parts.

[0046] The receiving mechanism includes four first guide rods 12 that are symmetrically arranged in pairs, and the four first guide rods 12 are fixedly arranged on the top of the adjustment seat 10. The outer wall of the first guide rod 12 is adjustable and sleeved with the same adjustment frame 16, and a receiving plate 13 is sleeved on the top. The receiving plate 13 and the adjustment frame 16 are connected by a first spring 15, and the two ends of the first spring 15 are respectively fixedly connected to the receiving plate 13 and the adjustment frame 16 close to each other on one side to achieve elastic reset of the receiving plate 13 and provide a stamping stroke. A through hole 14 is opened on the top of the receiving plate 13, and the size of the through hole 14 matches the parts to be received, such as the large end of the shaft, to ensure that the parts can fall into the receiving plate 13 smoothly.

[0047] The placement mechanism is arranged on the top seat 3 and is used to place the parts to be stamped and disassembled. The placement mechanism can be adjusted according to the height of the parts to ensure that the parts can be accurately docked with the piston rod of the hydraulic cylinder 4.

[0048] It mainly includes the second guide rod 24, the second screw rod 25, the guide block 30, the rack 21, the connecting seat 38, the lifting platform 22 and the waist-shaped hole 23. The second guide rod 24 is slidably arranged on one side of the top seat 3 to ensure its smooth movement in the horizontal direction. One end of the second guide rod 24 is fixedly connected to the guide block 30. A second screw rod 25 is also threadedly arranged on one side of the top seat 3, and one end of the second screw rod 25 is rotatably connected to the guide block 30. By rotating the second screw rod 25, the guide block 30 can be driven to move along the direction of the second guide rod 24.

[0049] At the top of the guide block 30, two racks 21 are slidably arranged, a rectangular groove is provided in the guide block 30, a slider is installed on the inner wall of the rectangular groove, a guide rail is installed on the side wall of the rack 21, and the rack 21 slides longitudinally in the guide block 30 through the guide rail slider. The position and height of the two racks 21 can be adjusted as needed to accommodate parts of different heights. A connecting seat 38 is fixedly connected to the bottom of the rack 21, and a lifting platform 22 can be installed on one side of the connecting seat 38 by means of bolts, etc. A waist-shaped hole 23 is provided on the top of the lifting platform 22 for accurately placing shaft parts to ensure their stability during the stamping process.

[0050] A rotating rod 26 is also rotatably provided on one side of the top seat 3, a worm 33 is fixedly sleeved on the outer wall of the rotating rod 26, and a worm wheel 34 meshing with the worm 33 is fixedly sleeved on the outer wall of the rotating shaft 31. By rotating the rotating rod 26, the worm 33 can be driven to rotate, thereby driving the worm wheel 34 and the rotating shaft 31 to rotate, and finally driving the rack 21 to move up and down through the gear 32.

[0051] The brake assembly mainly includes components such as a lifting block 35, a second sliding bar 39, an extension block 45, a guide column 43, a third spring 44, a second latch 40 and a second plug hole 41. The lifting block 35 is slidably sleeved on the two racks 21. A slider is installed on the inner wall of the lifting block 35. The slider is slidably connected to the guide rail of the side wall of the rack 21. The rack 21 slides longitudinally in the lifting block 35 through the guide rail slider. Since the rack 21 is longitudinally slidably connected with the guide block 30 and the lifting block 35 through the guide rail slider, when the guide block 30 moves laterally, the lifting block 35 is driven to move laterally through the guide rail slider and the rack 21. The second sliding bar 39 is slidably arranged inside one side. An extension block 45 is slidably arranged on the other side of the lifting block 35. One end of the extension block 45 is fixedly connected to the second sliding bar 39. The extension block 45 fits the arc surface of the output end of the hydraulic cylinder 4.

[0052] A first mounting hole 42 is provided on the inner wall of one side of the lifting block 35, and a guide column 43 is slidably provided in the first mounting hole 42, and one end of the guide column 43 is fixedly connected to the second sliding bar 39. A third spring 44 is sleeved on the outer wall of the guide column 43, and the two ends of the third spring 44 are respectively fixedly connected to the second sliding bar 39 and the lifting block 35 near each other, so as to provide a reset force for the second sliding bar 39.

[0053] A second latch 40 is fixedly provided on one side of the second sliding bar 39, and a plurality of second insertion holes 41 for use with the second latch 40 are provided on one side of the rack 21. In the process of rotating the second screw 25 to drive the guide block 30 to move, the rack 21 will be disengaged from the gear 32, and drive the second latch 40 to be inserted into the corresponding second insertion hole 41, so as to limit the rack 21 and prevent it from moving freely. Moreover, since the lateral length of the meshing between the rack 21 and the gear 32 is greater than the spacing between the second latch 40 and the second insertion hole 41, when the rack 21 is disengaged from the gear 32, the second latch 40 and the second insertion hole 41 have been plugged in.

[0054] A second mounting hole 46 is provided on one side of the extension block 45, and a plug rod 47 is slidably provided in the second mounting hole 46. A plug hole for use with the plug rod 47 is provided at the output end of the hydraulic cylinder 4. A fourth spring 48 located in the second mounting hole 46 is sleeved on the outer wall of the plug rod 47, and the two ends of the fourth spring 48 are respectively fixedly connected to the inner wall of one side of the second mounting hole 46 and the outer wall of the plug rod 47, so as to provide a reset force for the plug rod 47.

[0055] When the second latch 40 is inserted into the second insertion hole 41, the insertion rod 47 will be inserted into the output end insertion hole of the hydraulic cylinder 4 under the action of the lifting block 35, so as to realize the synchronous lifting and lowering movement of the two racks 21 and the hydraulic cylinder 4. When the connection needs to be disconnected, the second screw rod 25 is rotated in the reverse direction to drive the guide block 30 to move, and the rack 21 will mesh with the gear 32. The movement of the rack 21 can move the lifting block 35 and drive the second latch 40 to disengage from the corresponding second insertion hole 41, and at the same time drive the insertion rod 47 to move in the reverse direction to make it withdraw from the insertion hole, so as to release the connection with the hydraulic cylinder 4.

[0056] The present application can be used in the field of presses, and can also be used in other fields applicable to the present application.

[0057] Example 2

[0058] refer to Figure 1-Figure 8 A pressure machine with a safety protection mechanism and a gauge is applied to the field of pressure machines. In order to achieve accurate positioning of the adjustment seat 10, a plurality of first plug holes 19 are provided on one side of the vertical rod 2 along its length direction. When the adjustment seat 10 slides to the desired position, the first plug pin 20 is inserted into the first plug hole 19 of the corresponding height, so that the end of the first plug pin 20 contacts the bottom of the adjustment seat 10, thereby achieving stable positioning of the adjustment seat 10.

[0059] In order to further improve the flexibility of the receiving mechanism, two first sliding bars 17 are slidably provided in the adjusting frame 16. A pin 29 corresponding to the first guide rod 12 is slidably provided on the inner wall of one side of the adjusting frame 16, and the pin 29 is fixedly connected to the first sliding bar 17, while a plurality of positioning grooves 28 are provided on the outer wall of the first guide rod 12 to cooperate with the pin 29 to achieve the preliminary positioning of the adjusting frame 16. In addition, a bidirectional screw 18 is rotatably provided on one side of the adjusting frame 16, and the two first sliding bars 17 are respectively threadedly sleeved on the two threaded sections on the bidirectional screw 18. By rotating the bidirectional screw 18, the two first sliding bars 17 can be driven to move closer to or farther from each other, thereby achieving fine adjustment of the position of the adjusting frame 16 and the receiving plate 13 to meet the receiving requirements of parts of different sizes.

[0060] In order to realize the lifting and lowering movement of the rack 21, a connection frame 27 is fixedly provided on one side of the top seat 3, and a rotating shaft 31 is rotatably installed in the connection frame 27. The outer wall of the rotating shaft 31 is fixedly sleeved with a gear 32 meshing with the rack 21, and the gear 32 and the rack 21 are meshed and driven to drive the rack 21 to move up and down.

[0061] In order to ensure that the lifting block 35 can be smoothly reset after the connection with the hydraulic cylinder 4 is released, a third guide rod 36 is also slidably provided on the top of the guide block 30, and the bottom end of the third guide rod 36 is fixedly connected to the lifting block 35. The outer wall of the third guide rod 36 is sleeved with a second spring 37, and the two ends of the second spring 37 are respectively fixedly connected to the top of the guide block 30 and the outer wall of the top end of the third guide rod 36. After the connection is released, the lifting block 35 will reset and move under the action of the second spring 37 and return to the initial position.

[0062] In the present application, when the bearing and the sleeve need to be installed on the shaft, the adjusting seat 10 is pulled upward to adjust the position of the adjusting seat 10, and the first latch 20 is used to limit the position, and then the bearing and the sleeve are placed on the V-shaped block 11, and the rotating rod 26 is rotated. The rotation of the rotating rod 26 can drive the worm 33 to rotate, and the rotation of the worm 33 can drive the rotating shaft 31 to rotate through the worm gear 34. The rotation of the rotating shaft 31 can drive the gear 32 to rotate, and the rack 21 is meshed with the gear 32, so that the gear 32 can drive the rack 21 to move downward, and the downward movement of the rack 21 can drive the lifting platform 22 to move downward, and then the shaft is placed on the lifting platform 22, so that the large end of the shaft contacts the top of the lifting platform 22, and the small end is located in the waist-shaped hole 23.

[0063] Secondly, the rotating rod 26 is rotated in the opposite direction to drive the lifting platform 22 to move upward, so that the top of the shaft contacts the output end of the hydraulic cylinder 4, and then the second screw 25 is rotated. Since one end of the second screw 25 is rotatably connected to the guide block 30, and the second guide rod 24 passes through the top seat 3 and is fixedly connected to the guide block 30, the second screw 25 is threadedly connected to the top seat 3, and therefore, rotating the second screw 25 will drive the guide block 30 to move laterally along the direction of the second guide rod 24. When the second screw 25 rotates, due to the threaded cooperation between it and the top seat 3, the second screw 25 will move along its axial direction. Since the position of the top seat 3 remains unchanged, the second screw 25 will move relatively laterally on the top seat 3 when it rotates, and the movement of the second screw 25 can drive the guide block 30 to the top The seat 3 is close, which can drive the rack 21 away from the gear 32, that is, the rack 21 will be out of mesh with the gear 32, and the lateral movement of the rack 21 can drive the lifting block 35 to move horizontally. Since the output end of the hydraulic cylinder 4 is in conflict with the extension block 45, the lateral position of the extension block 45 will not move, so the lifting block 35 will slide horizontally on the extension block 45, that is, the lifting block 35 moves in the direction close to the output end of the hydraulic cylinder 4. During the movement, the second plug hole 41 on the rack 21 will gradually approach the second latch 40, and then the second latch 40 will be inserted into the corresponding second plug hole 41. When the second latch 40 is inserted into the second plug hole 41, the plug rod 47 will be inserted into the output end plug hole of the hydraulic cylinder 4 under the action of the lifting block 35. This is because a second mounting hole 46 is opened on one side of the extension block 45, and a plug rod 47 is slidably arranged in the second mounting hole 46. During the movement of the lifting block 35, the insertion rod 47 will be driven to move together, thereby realizing the connection between the insertion rod 47 and the socket at the output end of the hydraulic cylinder 4. In this way, the output end of the hydraulic cylinder 4 is connected to the rack 21 (through the lifting block 35 and the insertion rod 47).

[0064] The outer wall of the plug rod 47 is sleeved with a fourth spring 48 to provide a reset force for the plug rod 47. When the connection needs to be disconnected, the second screw rod 25 is rotated in the opposite direction to drive the guide block 30 to move laterally, so that the rack 21 and the gear 32 are re-engaged. At this time, the movement of the rack 21 will drive the lifting block 35 to move laterally and drive the second latch 40 to disengage from the corresponding second plug hole 41. At the same time, the plug rod 47 will also move in the opposite direction under the action of the fourth spring 48, withdraw from the output end plug hole of the hydraulic cylinder 4, and thus release the connection with the hydraulic cylinder 4;

[0065] Then, the hydraulic cylinder 4 is started to extend. During the extension process, the extension block 45 can be driven to move downward through the insertion rod 47 (because the insertion rod 47 has been inserted into the output end jack of the hydraulic cylinder 4 at this time). The downward movement of the extension block 45 can drive the lifting block 35 to move downward. The downward movement of the lifting block 35 can drive the rack 21 to move downward through the second latch 40 and the second insertion hole 41, and drive the lifting platform 22 to move downward, and at the same time drive the third guide rod 36 to move downward, and compress the second spring 37, thereby driving the shaft to move downward, so that the shaft is plugged into the bearing and the sleeve. After plugging, it is reversed again, and the second screw 25 drives the guide block 30 away from the top seat 3, so that the gear 32 and the rack 21 can be meshed, and the lifting platform 22 is driven away from the shaft through the rack 21. Then, the hydraulic cylinder 4 is started again to extend, and the shaft, the bearing and the sleeve are punched into place;

[0066] When the bearing and sleeve need to be taken out from the shaft, they are placed on the V-shaped block 11, and the shaft is placed in the two V-shaped blocks 11, and then the bidirectional screw 18 is rotated to drive the two first sliding bars 17 away from each other.
