Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a multifunctional pressure frame. Background Technology

[0002] A mechanical press is a mechanical device used to apply pressure. It is typically used for pressing, shaping, or processing materials. A mechanical press can apply uniform pressure to the workpiece through mechanical force to achieve the desired processing effect. This device is also needed for pressing and removing parts such as automotive suspension components and axle pin bushings.

[0003] Common mechanical press frames lack movable components at the lower end for changing installation positions and height adjustment devices. In addition, the pressing structure and its linkage structure can only work in one direction, resulting in a lack of flexibility in use.

[0004] Therefore, to address the issues of the aforementioned mechanical press lacking a movable component for interchangeable installation positions and an adjustment device for height adjustment at the lower end, and being limited to working in only one direction, thus requiring improved flexibility in use, this paper proposes an improvement to enhance the application scenarios. Utility Model Content

[0005] To overcome the common problems of mechanical pressure frames, lack of movable components for interchangeable installation positions and height adjustment devices, as well as the inability to switch working directions, the flexibility of use needs to be improved.

[0006] The technical solution of this utility model is as follows: a multifunctional pressure frame, including a lower mounting plate, connecting blocks are provided on the front and rear sides of the lower mounting plate near the left and right ends, a screw hole is opened in the middle of the connecting block, an installation sleeve is welded to the side of the connecting block away from the lower mounting plate, a support rod is installed on the top of the lower mounting plate near the corner, a movable plate is slidably connected in the middle of the support rod, an upper mounting plate is installed near the upper end of the support rod, a fixing screw is provided on the top of the support rod, a handle is connected to the fixing screw near the upper mounting plate, an adjustable moving component is installed in the middle of the connecting blocks, through holes are opened on the lower mounting plate, movable plate and upper mounting plate near the side, installation holes are opened on the lower mounting plate and movable plate near the through holes, a detachable hydraulic component is installed in the middle of the top of the movable plate, and an auxiliary reset component is connected between the through holes of the movable plate and the upper mounting plate.

[0007] Preferably, by changing the installation position of the adjustable movable component, the switching between movable and fixed states and the height adjustment can be realized. At the same time, by changing the installation position of the detachable hydraulic component and the auxiliary reset component, the working direction can be changed, improving the flexibility of use. This solves the problem that common mechanical presses lack movable components with interchangeable installation positions at the lower end, and the pressing structure and its linkage structure can only work in one direction, resulting in insufficient flexibility of use.

[0008] Preferably, the adjustable movable component includes a lifting screw, a first screw head, a socket, and a second screw head; the lifting screw is driven through the screw hole in the middle of the connecting block, the first screw head is installed at the bottom of the lifting screw, the first screw head has a socket in the middle with the same inner diameter as the mounting sleeve, and the second screw head is provided at the top of the lifting screw.

[0009] Preferably, the adjustable movable component includes a mounting screw, a first nut, a rotating bearing, and a movable wheel. The mounting screw passes through the insertion hole, with first nuts at both ends. A rotating bearing is connected to the mounting screw near the first nuts at the left and right ends. A movable wheel is mounted on the outside of the rotating bearing. At this point, the height is fixed but movable. The first nut is unscrewed, the rotating bearing and movable wheel are removed, the mounting screw is then inserted into the mounting sleeve, the rotating bearing and movable wheel are reinstalled, and the first nut is tightened. When the first screw head is above the ground, the movable state is achieved. By turning the second screw head or the first screw head, the height is lowered via the lifting screw. When the first screw head contacts the ground, the movable state is achieved. Continuing to turn the second screw head or the first screw head in the same direction allows for height adjustment.

[0010] Preferably, the detachable hydraulic assembly includes a connecting plate, a hydraulic cylinder, and a screw assembly. The connecting plate is installed at the top center of the movable plate, and the hydraulic cylinder is located on the top of the connecting plate. The upper end of the hydraulic cylinder contacts the bottom of the upper mounting plate. The connecting plate is connected to the mounting holes on the movable plate through the screw assemblies located at the corners. The parts to be pressed are placed between the lower mounting plate and the movable plate, and the detachable hydraulic assembly is extended to complete the downward pressing work. The hydraulic cylinder can be replaced with a manual hydraulic device. When upward pushing is required, the screw assembly is unscrewed, and the connecting plate and hydraulic cylinder are moved to the top of the lower mounting plate. The screw assembly is then fixed by passing through the mounting hole in the middle of the lower mounting plate, thereby changing the working direction and improving the flexibility of use.

[0011] Preferably, the auxiliary reset assembly includes a pull rod, a second nut, and a connecting ring; the pull rod is inserted into the through hole of the upper mounting plate, the second nut is connected to the outside of the pull rod at the top of the upper mounting plate, and a connecting ring is provided at the lower end of the pull rod. The traction length can be adjusted by turning the first screw head.

[0012] Preferably, the auxiliary reset assembly includes a first hook, a spring, and a second hook. The first hook is hung in the middle of the connecting ring, the bottom of the first hook is connected to the spring, and the second hook is installed at the lower end of the spring. The second hook is engaged with the through hole of the movable plate. When pressed down, the hydraulic cylinder or manual hydraulic device returns to its original position by gravity when pressure is released, which is inefficient. Therefore, the spring rebound pulls the movable plate upward to assist the hydraulic cylinder in returning to its original position. When the working direction changes to upward, the second hook is removed from the through hole of the movable plate, the second nut is unscrewed, the pull rod is removed from the through hole of the upper mounting plate, the pull rod is inserted downward into the through hole of the lower mounting plate, and the second hook is then engaged in the through hole of the movable plate. At this time, the spring rebound pulls the movable plate downward to assist the hydraulic cylinder in returning to its original position.

[0013] The beneficial effects of this utility model are:

[0014] Unscrew the first nut, remove the rotating bearing and movable wheel, then insert the mounting screw into the mounting sleeve, reinstall the rotating bearing and movable wheel, and tighten the first nut. When the first screw head is above the ground, it is in a movable state. By turning the second screw head or the first screw head, the lifting screw head lowers the screw head. When the first screw head contacts the ground, it is in a fixed state. Continue turning the second screw head or the first screw head in the same direction. At this point, the height can be adjusted. Place the parts to be pressed between the lower mounting plate and the movable plate, and control the extension of the detachable hydraulic assembly to complete the downward pressing work. The hydraulic cylinder can be replaced with a manual hydraulic device. When upward pushing is required, unscrew the screw assembly and then connect... The hydraulic cylinder moves to the top of the lower mounting plate and is fixed by screws passing through the mounting hole in the middle of the lower mounting plate, thus changing the working direction and improving the flexibility of use. When pressing down, some hydraulic cylinders or manual hydraulic devices return to their original position by gravity when depressurized, which is inefficient. Therefore, the spring rebound pulls the movable plate upward to assist the hydraulic cylinder in returning to its original position. When the working direction changes to upward, the second hook is removed from the through hole of the movable plate, the second nut is unscrewed, the pull rod is removed from the through hole of the upper mounting plate, the pull rod is inserted downward into the through hole of the lower mounting plate, and the second hook is hooked into the through hole of the movable plate. At this time, the spring rebound pulls the movable plate downward to assist the hydraulic cylinder in returning to its original position. Attached Figure Description

[0028] Please see Figure 1 , 3 4. In this embodiment, the adjustable moving component 9 includes a lifting screw 901, a first screw head 902, a socket 903, and a second screw head 904. The lifting screw 901 is connected to the screw hole in the middle of the connecting block 2. The first screw head 902 is installed at the bottom of the lifting screw 901. The first screw head 902 has a horizontally opened socket 903 in the middle. The socket 903 has the same inner diameter as the mounting sleeve 3. The second screw head 904 is provided at the top of the lifting screw 901. The adjustable moving component 9 includes a mounting screw 905, a first nut 906, a rotating bearing 907, and a movable wheel 908. The mounting screw 905 passes through the socket 903. The first nuts 906 are provided at the left and right ends of the mounting screw 905. The middle of the mounting screw 905 is near the left and right ends. A rotating bearing 907 is connected to the first nut 906 at both ends. A movable wheel 908 is installed on the outside of the rotating bearing 907. At this time, it is in a fixed height and movable state. Unscrew the first nut 906, remove the rotating bearing 907 and the movable wheel 908, then insert the mounting screw 905 into the mounting sleeve 3, reinstall the rotating bearing 907 and the movable wheel 908, and tighten the first nut 906. When the first screw head 902 is higher than the ground, it is in a movable state. By turning the second screw head 904 or the first screw head 902, the lifting screw 901 lowers the screw head 901. When the first screw head 902 contacts the ground, it is in a fixed state. Continue to turn the second screw head 904 or the first screw head 902 in the same direction. At this time, the height can be adjusted.

[0029] Please see Figure 1 , 35. In this embodiment, the detachable hydraulic assembly 12 includes a connecting plate 1201, a hydraulic cylinder 1202, and a screw sleeve 1203. The connecting plate 1201 is installed at the top center of the movable plate 5, and the hydraulic cylinder 1202 is provided at the top of the connecting plate 1201. The upper end of the hydraulic cylinder 1202 contacts the bottom of the upper mounting plate 6. The connecting plate 1201 is connected to the mounting hole 11 on the movable plate 5 through the screw sleeve 1203 provided at the corner. The parts to be pressed are placed between the lower mounting plate 1 and the movable plate 5, and the detachable hydraulic assembly 12 is extended to complete the downward pressing work. The hydraulic cylinder 1202 can be replaced with a manual hydraulic device. When it is necessary to push upward, the screw sleeve 1203 is unscrewed, and the connecting plate 1201 and the hydraulic cylinder 1202 are moved to the top of the lower mounting plate 1. The screw sleeve 1203 passes through the mounting hole 11 in the middle of the lower mounting plate 1 to fix it, thereby realizing the change of working direction and improving the flexibility of use.

[0030] Please see Figure 1 , 3 6. The auxiliary reset assembly 13 includes a pull rod 1301, a second nut 1302, and a connecting ring 1303. The pull rod 1301 is inserted into the through hole 10 of the upper mounting plate 6. The second nut 1302 is connected to the outside of the pull rod 1301 at the top of the upper mounting plate 6. The connecting ring 1303 is provided at the lower end of the pull rod 1301. The traction length can be adjusted by turning the first screw head 902. The auxiliary reset assembly 13 includes a first hook 1304, a spring 1305, and a second hook 1306. The first hook 1304 is hung in the middle of the connecting ring 1303. The spring 1305 is connected to the bottom of the first hook 1304. The second hook 1306 is installed at the lower end of the spring 1305. When the movable plate 5 is connected to the through hole 10, and pressed down, the hydraulic cylinder 1202 or the manual hydraulic device returns to its original position by gravity when the pressure is released, which is inefficient. Therefore, the movable plate 5 is pulled upward by the rebound of the spring 1305 to return the auxiliary hydraulic cylinder 1202. When the working direction changes to upward, the second hook 1306 is taken out from the through hole 10 of the movable plate 5, the second nut 1302 is unscrewed, the pull rod 1301 is taken out from the through hole 10 of the upper mounting plate 6, the pull rod 1301 is inserted downward into the through hole 10 of the lower mounting plate 1, and the second hook 1306 is hooked into the through hole 10 of the movable plate 5. At this time, the movable plate 5 is pulled downward by the rebound of the spring 1305 to return the auxiliary hydraulic cylinder 1202.

[0031] When the installation screw 905 is inserted into the insertion hole 903, it is in a fixed height but movable state. Unscrew the first nut 906, remove the rotating bearing 907 and the movable wheel 908, then insert the installation screw 905 into the installation sleeve 3, reinstall the rotating bearing 907 and the movable wheel 908, and tighten the first nut 906. When the first screw head 902 is above the ground, it is in a movable state. The screw can be raised or lowered by turning the second screw head 904 or the first screw head 902. When the first screw head 902 contacts the ground, it is in an immovable state. Continuing to turn the second screw head 904 or the first screw head 902 in the same direction allows for height adjustment. The traction length can be adjusted by turning the first screw head 902. The parts to be pressed are placed between the lower mounting plate 1 and the movable plate 5. Controlling the extension of the detachable hydraulic assembly 12 completes the downward pressing operation. The hydraulic cylinder 1202 can be replaced with a manual hydraulic device. When upward pushing is required, the screw sleeve 1203 is unscrewed, and the connecting plate 1201 and hydraulic cylinder 1202 are moved to the top of the lower mounting plate 1. The screw sleeve 1203 is fixed by passing through the mounting hole 11 in the middle of the lower mounting plate 1, thus changing the working direction and improving operational flexibility. When pressing downwards, due to pressure loss in some hydraulic cylinders 1202 or the manual hydraulic device, the return to position is achieved by gravity, which is inefficient. Therefore, the spring 1305's rebound pulls the movable plate 5 upwards to assist the hydraulic system. When the cylinder 1202 returns to its original position, and the working direction changes to upward, the second hook 1306 is removed from the through hole 10 of the movable plate 5, the second nut 1302 is unscrewed, the pull rod 1301 is removed from the through hole 10 of the upper mounting plate 6, the pull rod 1301 is inserted downward into the through hole 10 of the lower mounting plate 1, and then the second hook 1306 is hooked into the through hole 10 of the movable plate 5. At this time, the spring 1305 can pull the movable plate 5 downward to return the auxiliary hydraulic cylinder 1202 to its original position.

[0032] Through the above steps, by changing the installation position of the adjustable movable component 9, the switching between movable and fixed states and the height adjustment can be realized. At the same time, by changing the installation position of the detachable hydraulic component 12 and the auxiliary reset component 13, the working direction can be changed, improving the flexibility of use. This solves the problem that common mechanical presses lack movable components with interchangeable installation positions at the lower end, and that the pressing structure and its linkage structure can only work in one direction, resulting in insufficient flexibility of use.

[0033] Another example:

[0034] See Figure 7-10In this specific embodiment, another type of support plate 21 is provided to replace the function of the mounting plate 6. At the same time, in order to cooperate with the support plate 21, a hydraulic cylinder is also provided in this embodiment. The hydraulic cylinder includes a cylinder body 31 and a hydraulic slide rod 32 slidably disposed in the cylinder body. The end of the hydraulic slide rod can also be detachably fitted with a top block 33, and the top block 33 is provided with a plurality of first mounting holes 331. The top block can be fitted with pressure plates of different sizes through the first mounting holes 331 (not shown in the figure); or the top block 33 can be directly used for pressing.

[0035] The support plate 21 has second mounting holes 211 on both sides for fitting with the support rod 4. The support plate 21 also has a central hole 212 for the oil pressure slide rod 32 to pass through. The support plate 21 also has several third mounting holes 214 for fixing the cylinder body 31. The outer wall of the cylinder body 31 has a ring of mounting protrusions 311, and the mounting protrusions 311 have several fourth mounting holes 3111 aligned with the third mounting holes 214.

[0036] In this specific embodiment, the pull-down movable plate 5 and spring 1305 can be omitted because the hydraulic cylinder in this embodiment has an automatic rebound function, so spring 1305 is no longer needed. In addition, in this embodiment, the pull-down movable plate 5 is replaced by a top block 33, so the top block 33 is driven by the hydraulic slide rod 32 to press the workpiece. It should also be noted that a reinforcing rib 215 is provided on the surface of the support plate 21 to enhance the overall strength of the support plate 21.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
