Description

Technical Field

[0001] The present application relates to the field of press-fit assembly tools, and in particular to a press-fit riveting tool for assembling rollers for hydraulic pipes. Background Art

[0002] Rollers can be used to organize hydraulic pipes in large machinery, and play a guiding and limiting role for hydraulic pipes. Rollers are rotatably connected in large machinery, and grooves are opened on the rollers. Hydraulic pipes can be stuck in the grooves of the rollers. When the machinery moves, the rollers rotate to make the hydraulic pipes move back and forth, reducing the probability of the hydraulic pipes moving randomly and getting entangled with each other in the machinery.

[0003] Existing rollers are usually made of elastic rubber materials so that the hydraulic pipe can be stuck in the groove of the roller. The rubber material has poor wear resistance. After the roller rotates many times, the middle part of the roller is severely worn. In order to increase the service life of the roller, an inner sleeve is usually arranged in the middle of the roller. The inner sleeve is made of a material with poor elasticity and good wear resistance. The inner sleeve is a round tube structure. The inner sleeve is inserted into the center hole of the roller and has an interference fit with the center hole of the roller. By arranging the inner sleeve in the roller, the inner sleeve contacts and rubs against the rotating shaft, thereby increasing the service life of the roller.

[0004] The above-mentioned related technical solutions have the following defects: in the production process, the process of inserting the inner sleeve into the roller needs to be completed manually by the user, and the inner sleeve and the roller have an interference fit, so the inner sleeve is difficult to be quickly inserted into the roller, resulting in low roller production efficiency. Utility Model Content

[0005] In order to improve the efficiency of inserting an inner sleeve into a roller, the present application provides a riveting tool for assembling a roller for a hydraulic pipe.

[0006] The present application provides a riveting tool for assembling a roller for a hydraulic pipe, which adopts the following technical solution:

[0007] A riveting tool for assembling rollers for hydraulic pipes comprises a base, a workbench, a connecting seat, a pressure rod and a lower pressure column. The workbench is fixed on the base, the connecting seat is fixed on the workbench, one end of the pressure rod is rotatably connected to the connecting seat, and the lower pressure column is arranged in the middle of the pressure rod, and the lower pressure column is located on one side of the pressure rod close to the workbench.

[0008] By adopting the above technical solution, a connecting seat is arranged on the workbench, so that the pressure rod can be rotated to a state parallel to the workbench, so that the workbench and the pressure rod can jointly clamp the roller and the inner sleeve. The user can make the end face of one end of the roller fit on the workbench and insert the inner sleeve into the other end face of the roller, so that the lower pressure column can abut against the inner sleeve and push the inner sleeve to move downward, so that the inner sleeve can be pressed into the roller, and the lower pressure column can abut against the inner sleeve and the end face of the roller, so that the end of the inner sleeve is flush with the end face of the roller, so that the assembly efficiency of the roller and the inner sleeve is higher and the installation quality is better.

[0009] Optionally, the lower pressure column includes a base column and a rotating rod, one end of the rotating rod is connected to the base column, and the other end is rotatably connected to the pressure rod, and the rotating axis formed by the rotating rod and the pressure rod is parallel to the rotating axis formed by the pressure rod and the connecting seat.

[0010] By adopting the above technical solution, by connecting the base column and the rotating rod, the base column can be rotatably connected to the pressure rod through the rotating rod. When the pressure rod is rotated downward, the user can turn the rotating rod to make the base column fall vertically and press on the end face of the roller, so that the lower pressure column can apply vertical pressure to the inner sleeve, making it convenient to press the inner sleeve into the roller.

[0011] Optionally, a latch is provided on one end of the base column away from the rotating rod, the base column and the latch are cylinders, the latch is coaxially connected to the base column, and the diameter of the latch is smaller than the diameter of the base column.

[0012] By adopting the above technical solution, a pin is arranged on the base column so that the pin can be inserted into the inner sleeve. When the pressure rod is pressed down, the user inserts the pin into the inner sleeve to make the downward pressure column and the inner sleeve engage, thereby reducing the probability of the inner sleeve and the roller slipping on the workbench.

[0013] Optionally, the base column and the rotating rod are detachably connected.

[0014] By adopting the above technical solution, by making the base column and the rotating rod detachably connected, the user can connect base columns and pins of different sizes to the rotating rod, thereby facilitating the user to assemble rollers and inner sleeves of different sizes.

[0015] Optionally, a plurality of suction cups are provided on a surface of a side of the base away from the workbench, and the suction cups are used to adsorb on the desktop.

[0016] By adopting the above technical solution and arranging a plurality of suction cups on the base, when the base is placed on a desktop, the suction cups can be adsorbed on the desktop, thereby reducing the probability of the base sliding horizontally on the desktop.

[0017] Optionally, a limit countersunk hole is provided on the workbench, and the limit countersunk hole is used to clamp the roller.

[0018] By adopting the above technical solution, a limiting countersunk hole is opened on the workbench, so that the bottom end surface of the roller can be stuck in the limiting countersunk hole, thereby reducing the probability of the roller slipping on the workbench.

[0019] Optionally, a return spring is provided on the connecting seat, one end of the return spring is connected to the connecting seat, and the other end is connected to the pressure rod, and the return spring is used to lift the pressure rod in a natural state.

[0020] By adopting the above technical solution, a reset spring is arranged on the connecting seat, so that the reset spring can pull the pressure rod to keep the pressure rod in an upward state. After the user rotates the pressure rod to press the inner sleeve into the roller, the reset spring drives the pressure rod to lift up when the pressure rod is released, thereby making it convenient for the user to take out the assembled roller and put the roller to be assembled on the workbench.

[0021] Optionally, a connecting column 1 is installed on the connecting seat, a connecting column 2 is installed on the pressure rod, and hanging rings are fixed on both ends of the reset spring, and the hanging rings are used to be mounted on the connecting column 1 or the connecting column 2.

[0022] By adopting the above technical solution, by setting connecting column one on the connecting seat and connecting column two on the pressure rod, the end of the reset spring can be hung on the connecting column through the hanging ring, thereby making it convenient for users to replace the aged reset spring.

[0023] In summary, the beneficial technical effects of this application are:

[0024] 1. By setting a connecting seat on the workbench, the pressure rod can be rotated to a state parallel to the workbench, so that the workbench and the pressure rod can clamp the roller and the inner sleeve together. The user can make the end face of one end of the roller fit on the workbench and insert the inner sleeve on the other end face of the roller, so that the lower pressure column can abut on the inner sleeve and push the inner sleeve to move downward, so that the inner sleeve can be pressed into the roller, and the lower pressure column can abut on the inner sleeve and the end face of the roller, so that the end of the inner sleeve is flush with the end face of the roller, so that the assembly efficiency of the roller and the inner sleeve is high and the installation quality is good;

[0025] 2. By connecting the base column and the rotating rod, the base column can be rotatably connected to the pressure rod through the rotating rod. When the pressure rod rotates downward, the user can turn the rotating rod to make the base column fall vertically and press on the end surface of the roller, so that the lower pressure column can apply vertical pressure to the inner sleeve, which is convenient for pressing the inner sleeve into the roller;

[0026] 3. By arranging a reset spring on the connecting seat, the reset spring can pull the pressure rod to keep the pressure rod in an upward state. After the user rotates the pressure rod to press the inner sleeve into the roller, the reset spring drives the pressure rod to lift up when the pressure rod is released, thereby facilitating the user to take out the assembled roller and put the roller to be assembled on the workbench.

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] The present application embodiment discloses a press riveting tool for assembling a roller for a hydraulic pipe, referring to Figure 1 and Figure 2 , including a base 1, a workbench 2, a connecting seat 3, a pressure rod 4 and a lower pressure column 5, the workbench 2 is fixed on the base 1, the connecting seat 3 is fixedly connected to one side of the workbench 2, one end of the pressure rod 4 is rotatably connected to the connecting seat 3, and the lower pressure column 5 is arranged in the middle of the pressure rod 4, and the lower pressure column 5 is located on the side of the pressure rod 4 close to the workbench 2. When the user places the roller 6 on the workbench 2, by holding the pressure rod 4 and rotating the pressure rod 4, the lower pressure column 5 can fall and abut on the roller 6, so that the inner sleeve 61 can be inserted into the center hole of the roller 6. The lower pressure column 5 is pressed on the end surface of the inner sleeve 61 and the roller 6, so that the end of the inner sleeve 61 is flush with the end surface of the roller 6, thereby improving the processing quality and efficiency.

[0034] Reference Figure 2 A plurality of suction cups 11 are arranged on the surface of the base 1 on one side away from the workbench 2. When the user places the base 1 horizontally on the desktop, the suction cups 11 are adsorbed on the desktop, thereby improving the connection stability between the base 1 and the desktop, reducing the chance of the base 1 slipping on the desktop, and facilitating use.

[0035] Reference Figure 2A limiting countersunk hole 21 is provided on the surface of the side of the workbench 2 away from the base 1. The limiting countersunk hole 21 is a circular hole. The user can vertically place the roller 6 in the limiting countersunk hole 21, so that the roller 6 can be stuck in the limiting countersunk hole 21, reducing the probability of the roller 6 slipping when the pressing column 5 presses down the roller 6, thereby improving the processing efficiency.

[0036] Reference Figure 3 A return spring 32 is provided on the connection seat 3, one end of the return spring 32 is connected to the connection seat 3, and the other end is connected to the pressure rod 4. The return spring 32 pulls the pressure rod 4 to keep the pressure rod 4 in a naturally lifted state. When the user rotates the pressure rod 4 and completes the installation of the inner sleeve 61 in the roller 6, the user releases the pressure rod 4, and the pressure rod 4 is lifted up under the drive of the return spring 32, so that the user can take out the processed roller 6 and put the roller 6 and the inner sleeve 61 to be processed on the workbench 2.

[0037] Reference Figure 3 A connecting column 1 31 is fixedly connected to the connecting seat 3, and the connecting column 1 31 is fixed on the surface of the connecting seat 3 on the side away from the lower pressure column 5. A connecting column 2 41 is fixed on the pressure rod 4, and the connecting column 2 41 is fixed on the end of one side of the pressure rod 4 close to the connecting seat 3. Both ends of the reset spring 32 are fixedly connected with hanging rings 321. The user can respectively put the two hanging rings 321 on the connecting column 1 31 and the connecting column 2 41, so that the two ends of the reset spring 32 can be connected to the connecting seat 3 and the pressure rod 4 respectively, which is convenient for the user to replace the aging reset spring 32.

[0038] Reference Figure 3 The lower pressure column 5 includes a base column 51, a latch 52 and a rotating rod 53. The base column 51 and the latch 52 are cylindrical. The base column 51 and the rotating rod 53 are connected. One end of the rotating rod 53 away from the base column 51 is rotatably connected to the pressure rod 4. The rotation axis formed by the rotating rod 53 and the pressure rod 4 is parallel to the rotation axis formed by the pressure rod 4 and the connecting seat 3. When the user rotates the pressure rod 4, the other hand can move the base column 51 to move the base column 51 vertically downward. The latch 52 is coaxially connected to the end of the base column 51 away from the rotating rod 53, and the diameter of the latch 52 is smaller than the diameter of the base column 51. When the user needs to insert the inner sleeve 61 into the roller 6, the user can put the inner sleeve 61 on the latch 52, and then insert one end of the inner sleeve 61 into the roller 6. At this time, pressing down the pressure rod 4 can make the lower pressure column 5 press on the roller 6, and the latch 52 has a positioning effect to reduce the probability of the roller 6 slipping on the workbench 2. The base column 51 abuts against the end faces of the inner sleeve 61 and the roller 6, so that after the inner sleeve 61 is inserted into the roller 6, the ends of the inner sleeve 61 and the roller 6 are flush.

[0039] Reference Figure 4In other embodiments, the rotating rod 53 is detachably connected to the base column 51, a screw is provided on the rotating rod 53, a threaded hole is provided on the base column 51, and the base column 51 is threadedly connected to the rotating rod 53. The user can set base columns 51 and latches 52 of different sizes on the rotating rod 53, thereby facilitating the user to install rollers 6 and inner sleeves 61 of different specifications.

[0040] The implementation principle of the embodiment of the present application is: by setting a workbench 2 on the base 1, rotating the connecting pressure rod 4 on the connecting seat 3, so that the pressure rod 4 can drive the lower pressure column 5 to move, and then the lower pressure column 5 can press the inner sleeve 61 into the roller 6, and by setting a pin 52 on the base column 51, the pin 52 can be inserted into the inner sleeve 61, and then the pin 52 plays a limiting role. When the pressure rod 4 falls, the probability of the roller 6 slipping on the workbench 2 can be reduced.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
