Description

Technical Field

[0001] The utility model relates to the technical field of shaft sleeve press-fitting, in particular to a shaft sleeve press-fitting tool. Background Art

[0002] Both bearings and sleeves are used to connect two objects. Bearings connect two stationary objects, while sleeves connect two moving objects. Sleeves prevent bearing damage from excessive vibration. The difference between bearings and sleeves is that the former is a separate component, while the latter is an integral part of the bearing. Typically, a sleeve consists of an outer ring, which is fixed to the machine body, and an inner ring, which fits over the bearing. Bearings and sleeves have opposite functions: the former supports the shaft, while the latter supports the outer ring.

[0003] Currently, most of the bushing press-fitting tools require the user to manually place the bushing. During the placement process, if the user does not align the bushing with the shaft, the bushing and the shaft will collide when the cylinder presses the bushing, causing damage to the parts and increasing production costs.

[0004] Therefore, the present application provides a shaft sleeve press-fitting tool to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a shaft sleeve press-fitting tool. When the device is in use, the shaft sleeve body and the rotating shaft are press-fitted together through the press-fitting mechanism, thereby avoiding manual errors and damage to the shaft sleeve and the rotating shaft during press-fitting. In addition, the storage box is convenient for users to place multiple shaft sleeve bodies at one time without the need to align them one by one, thus saving time and improving production efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shaft sleeve press-fitting tool, comprising a press-fitting mechanism, a chassis and a fixing mechanism, the press-fitting mechanism comprising a support block and a No. 1 bracket, two No. 1 oil cylinders are fixedly provided on the upper end of the support block, and the output ends of the two No. 1 oil cylinders are fixedly provided with a fixing block, a fixing frame is fixedly provided on the side of the fixing block away from the support block, a No. 1 spring is fixedly provided inside the side of the fixing frame away from the support block, a slider is fixedly provided on one end of the No. 1 spring, and through holes are formed through the fixing block and the fixing frame at one end close to the support block;

[0007] A storage box is fixedly provided inside the upper end of the No. 1 bracket. The upper and lower ends of the storage box pass through the storage box. The lower end of the storage box is in contact with the upper end of the fixed frame. A baffle is fixedly provided on the upper end of the fixed frame near the support block. Five No. 1 springs and sliders are provided around the sleeve body. The fixing mechanism includes a No. 2 bracket, a No. 3 bracket and two lower bases.

[0008] Through the above technical solution, when the device is in use, the sleeve body falls from the storage box to the inside of the fixed frame, and is then fixed by multiple sliders. Then, the two No. 1 oil cylinders push the fixed frame through the fixed blocks. When the sleeve body is fixed around the rotating shaft, the lower base fits against one side of the sleeve body. The lower base will squeeze the multiple sliders downward, and then the fixed frame will be retracted. The sliders will fit against the surface of the sleeve body and will not block the sleeve body, completing the press-fitting of the sleeve body. This is beneficial for aligning the sleeve body and the rotating shaft without manual work, avoiding errors that may cause damage to the sleeve body and the rotating shaft. In addition, when the strange box moves, the baffle will block the lower end of its storage box to prevent other sleeve bodies from continuing to fall. When the fixed frame is recovered, the sleeve body continues to fall, which is beneficial for users to load multiple sleeve bodies at a time, saving loading time and improving production efficiency.

[0009] Furthermore, the chassis includes a shell, and access doors are rotatably provided on both sides of the front interior of the shell, and handles are fixedly provided at the front ends of the two access doors, and four support bases are fixedly provided at the lower end of the shell;

[0010] Through the above technical solution, the outer shell is conducive to the installation of the press-fitting mechanism and the fixing mechanism, and the handle and the maintenance door are conducive to regular maintenance of the chassis to ensure its normal operation.

[0011] Furthermore, one of the two lower bases is slidably arranged on a side of the upper end of the second bracket close to the press-fitting mechanism, and the other of the two lower bases is fixedly arranged on a side of the upper end of the second bracket away from the press-fitting mechanism;

[0012] The above technical solution is conducive to placing the rotating shaft. The sliding lower base is conducive to adjusting the telescopic distance from the No. 1 oil cylinder during the pressing work, which is conducive to pressing the sleeve body into different positions at one end of the rotating shaft.

[0013] Furthermore, a second spring and a telescopic rod are connected between the two lower bases, and a rotating shaft is provided inside the upper ends of the two lower bases;

[0014] The above technical solution is conducive to the lower base returning to its original position after moving.

[0015] Furthermore, the third bracket is fixedly arranged on one side of the upper end of the housing, the upper end of the third bracket close to the second bracket is fixedly provided with a second oil cylinder, and the lower end of the second oil cylinder is fixedly provided with an upper base;

[0016] Through the above technical solution, the upper base is pushed by the No. 2 oil cylinder, which is conducive to fixing the rotating shaft and avoiding shaking during the pressing process.

[0017] Furthermore, the upper ends of the two No. 1 oil cylinders are fixedly provided with a slide groove, and the baffle is slidably provided between the two slide grooves;

[0018] Through the above technical solution, the two sliding grooves can help make the baffle more stable during movement and will not shake easily.

[0019] Furthermore, a connecting rod is connected between the support block and the second bracket, and the fixing block is slidably arranged around the connecting rod;

[0020] Through the above technical solution, the connecting rod is used to make the fixed block more stable during movement, avoiding inconsistent upper and lower angles that may cause damage to the sleeve body or the rotating shaft.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a shaft sleeve pressing tool. When the device is in use, the two No. 1 oil cylinders push the fixed block and the fixed frame to move, and the shaft sleeve body inside the fixed frame is fixed around one end of the rotating shaft. When the shaft sleeve body is fixed around the rotating shaft, one side of the lower base and one side of the shaft sleeve body fit together, and multiple sliders are pressed downward, and then the fixed frame is retracted. At this time, the sliders will fit around the shaft sleeve body and will not drive the shaft sleeve body to move, which is conducive to the rapid positioning and installation of the shaft sleeve body and the rotating shaft. In addition, the user can load multiple shaft sleeve bodies into the storage box at a time, and the shaft sleeve body at the bottom will fall into the fixed frame. When the fixed frame is pushed, the baffle will block the remaining shaft sleeve bodies. When the fixed frame returns to its original position, it falls again, which is conducive to saving the user's operation time.

[0023] 2. The utility model proposes a shaft sleeve press-fitting tool. When the device is in use, since one of the two lower bases is slidably set on the upper end of the No. 2 bracket, when the shaft sleeve body needs to be installed in a deeper position, the sliding lower base can be directly pushed to move together. After the installation is completed, the lower base will return to its original position under the push of the No. 2 spring, which is conducive to adjusting the installation position of the shaft sleeve body so that it can be installed at different positions at one end of the rotating shaft.

[0034] The two No. 1 oil cylinders 109 can push the fixed frame 101 and the fixed block 111. The fixed frame 101 is conducive to limiting the sleeve body 102 so that it can be aligned with the rotating shaft 302, which is convenient for fixing it around the rotating shaft 302. The slider 103 and the No. 1 spring 104 are conducive to limiting the sleeve body 102 before it is fixed. After the sleeve body 102 is fixed around the rotating shaft 302, the lower base 303 will be aligned with the sleeve body 102, and the slider 103 will be squeezed into the fixed frame 101 so that it will not drive the sleeve body 102 to move.

[0035] A storage box 105 is fixedly provided inside the upper end of the No. 1 bracket 106, and the upper and lower ends of the storage box 105 are penetrated.

[0036] The storage box 105 is convenient for storing multiple sleeve bodies 102. The sleeve body 102 at the bottom of the storage box 105 will fall into the fixed frame 101. When the fixed frame 101 moves, the baffle 107 will block the remaining sleeve bodies 102 to prevent them from falling. When the fixed frame 101 returns to its original position, the sleeve body 102 will fall again, which can improve work efficiency.

[0037] The chassis 2 includes a shell 201, and both sides of the front end of the shell 201 are rotatably provided with maintenance doors 202.

The lower end of the No. 2 oil cylinder 301 is fixedly provided with an upper base 306, and the upper ends of the two No. 1 oil cylinders 109 are fixedly provided with a slide groove 108, and the baffle 107 is slidably provided in the middle of the two slide grooves 108, which is conducive to making the baffle 107 more stable during the movement. A connecting rod 112 is connected between the support block 110 and the No. 2 bracket 304, and the fixed block 111 is slidably provided around the connecting rod 112, which is conducive to making the fixed block 111 more stable during the movement.

[0038] Working principle: When the device is in use, the user fills multiple sleeve bodies 102 into the storage box 105, and the lowermost one will fall into the fixed frame 101 and be fixed by multiple sliders 103. Then, two No. 1 oil cylinders 109 push the fixed block 111 and the fixed frame 101 to move and fix the sleeve body 102 around one end of the rotating shaft 302. At this time, one side of the lower base 303 is in contact with the sleeve body 102, and the multiple sliders 103 are pressed toward the surrounding area to make it fit around the lower base 303. Then, the fixed frame 101 is retracted. At this time, the sliders 103 are in contact with the surrounding area of ​​the sleeve body 102 and will not drive the sleeve body 102 to move. When the fixed frame 101 returns to its original position, the remaining sleeve bodies 102 continue to fall.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
