Description

Technical Field

[0001] This utility model relates to the technical field of pin disassembly tools, specifically an automatic sliding hammer puller for disassembling pins using a six-sided top press. Background Technology

[0002] Six-sided top presses are widely used in industrial production, and their internal pins require disassembly, maintenance, or replacement after prolonged use. However, due to the structural characteristics and working environment of six-sided top presses, the pins are often subjected to significant pressure and friction, making disassembly extremely difficult and thus requiring the use of tools.

[0003] In the prior art, the utility model patent with patent number CN201821627021.6 discloses a sliding hammer puller for disassembling shafts and bearings, including a long shaft, one end of which is threaded and screwed to a head shaft with an internal threaded hole. The head shaft has a round boss at its head and a slotted hole in the middle. Fixing screws a and b are installed at both ends of the slotted hole. A handle shaft for gripping is installed in the middle of the long shaft. The handle shaft is ellipsoidal and has a hole in the middle that allows it to slide along the long shaft. The other end of the long shaft is a tail shaft with an internal threaded hole, and an external screw is screwed to the internal threaded hole of the tail shaft.

[0004] The aforementioned patent provides a sliding hammer puller for disassembling pins. This device involves manually controlling a pulling hammer to strike a pulling rod back and forth. Through the inertia of the impact, the pulling rod can gradually slide the pin out. Although this device can effectively help workers complete the disassembly work, it relies on manual control of the pulling hammer to strike the pulling rod back and forth, which is not only labor-intensive but also inefficient. Furthermore, it is difficult for workers to accurately control the force applied each time, which can easily lead to excessive force and damage to the workpiece. Further improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic sliding hammer puller for disassembling pins using a six-sided top press. The aim is to improve upon the existing sliding hammer puller, which, although it can effectively help workers complete the disassembly work, relies on manual control of the pull hammer to strike the pull rod back and forth. This not only results in a large workload and low efficiency, but also makes it difficult for workers to accurately control the force applied each time, which can easily lead to excessive force and damage to the workpiece.

[0006] This utility model is implemented as follows: An automatic sliding hammer puller for disassembling pins in a six-sided top press includes a sliding rod and a sliding hammer, as well as a rotating component; the sliding rod is integrally formed from left to right with a mounting post, an impact seat, a guide rod, and a threaded joint, and a limit block is installed on the threaded joint, with the limit block extending from the threaded joint and threaded onto the pin; the guide rod is fitted with a sliding hammer and a spring, one end of the spring abutting against the sliding hammer and the other end abutting against the limit block, and the sliding hammer elastically abutting against the impact seat through the spring; one end of the rotating component is provided with a rotating chuck, and the other end is detachably provided with a pushing component, and the mounting post is rotatably installed on the pushing component; the outer ring surface of the sliding hammer is provided with multiple stops along its circumference, and a pushing inclined surface is provided on one inner side of each stop; the pushing component is provided with a push rod corresponding to the position of the pushing inclined surface, and the end of the push rod abuts against the pushing inclined surface.

[0007] Preferably, the rotating component further includes a connecting bolt, the pushing component includes a connecting plate, one end face of the connecting plate is provided with a rotating component via the connecting bolt, and the other end face is provided with a push rod; a rotating hole is opened at the center of the connecting plate, a thrust bearing is provided on the rotating hole, and the mounting column is rotatably mounted on the rotating hole via the thrust bearing.

[0008] Preferably, it also includes a fixing nut, wherein the end of the mounting post extends into a thrust bearing and is provided with a threaded surface, and the fixing nut is threaded onto the threaded surface at the end of the mounting post.

[0009] Preferably, the guide rod includes a guide plate, and the guide plate is symmetrically arranged on the side of the guide rod along its length direction. The center position of the sliding hammer is provided with a sliding hole that matches the guide rod, and the sliding hammer is slidably mounted on the guide rod through the sliding hole.

[0010] Preferably, the slide hammer further includes an impact head, and the end face of the slide hammer and the impact seat that abuts is provided with an impact head that is adapted to the impact seat.

[0011] Preferably, it also includes a mounting nut, wherein the limiting block is fitted onto the threaded joint and is fixedly installed by the mounting nut.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model provides a pusher on the rotating part to push the slide hammer, causing the slide hammer to compress the spring to a fixed distance. Then, the elastic release of the spring pushes the slide hammer to impact the impact seat, ensuring that the force of each impact is the same. This also ensures that the tension on the pin is the same each time. At the same time, the impact force can be controlled by changing the spring with different elasticity to avoid excessive force that could damage the workpiece. Furthermore, it eliminates the need for manual sliding of the slide hammer, reducing the difficulty of operation for workers.

[0015] 2. This utility model has a stop block with a pushing slope on the slide hammer, which can be moved by sliding the push rod on the pushing slope. It is simple and convenient. Attached Figure Description

[0025] Example 1

[0026] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, an automatic sliding hammer puller for disassembling pins using a six-sided top press includes a sliding rod 3 and a sliding hammer 4, as well as a rotating component 1. The sliding rod 3 is integrally formed from left to right with a mounting post 301, an impact seat 302, a guide rod 303, and a threaded joint 304. A limit block 8 is mounted on the threaded joint 304, and the limit block 8 extends from the threaded joint 304 and is threaded onto the pin. It also includes a mounting nut 9, which secures the limit block 8 to the threaded joint 304. The mounting nut 9 fixes the limit block 8 to the threaded joint 304, preventing it from falling off during operation. The guide rod 303 is fitted with the sliding hammer 4 and a spring 5. One end of the spring 5 abuts against the sliding hammer 4, and the other end abuts against the limit block 8. The sliding hammer 4 elastically abuts against the impact seat 302 via the spring 5. The sliding hammer 4 also includes an impact head 404. The end face of the sliding hammer 4 that abuts against the impact seat 302 is provided with an impact head 404 that is adapted to the impact seat 302. The guide rod 303 includes a guide plate 305. The guide plate 305 is symmetrically arranged on the side of the guide rod 303 along its length. The center position of the sliding hammer 4 is provided with a sliding hole 401 that is adapted to the guide rod 303. The sliding hammer 4 is slidably mounted on the guide rod 303 through the sliding hole 401. By setting the guide plate 305, the sliding hammer 4 will not rotate during the sliding along the guide plate 305. The sliding hammer 4 abuts against the impact seat 302 through the spring 5, so that the sliding hammer 4 is subjected to a certain elastic thrust, and the sliding hammer 4 automatically impacts the impact seat 302 through the elasticity of the spring 5.

[0027] like Figures 2-6As shown, one end of the rotating component 1 is provided with a rotating chuck 101, which has a three-sided flat structure for connecting external power tools. The rotating chuck 101 has three flat sides arranged sequentially along its circumference, which can be adapted to the three-jaw chuck of existing electric drills. The electric drill can clamp the rotating chuck 101 through the chuck, driving it to rotate. Operation is simple and convenient, and it is easy to select the rotating tool. The other end is detachably provided with a pusher 2, and a mounting post 301 is rotatably mounted on the pusher 2. By clamping the rotating end of the external power tool onto the rotating chuck 101, the rotating component 1 can be easily driven to rotate by the external power tool. The rotating component 1 also includes a connecting bolt 102, and the pusher 2 includes a connecting plate 201. The rotating component 1 is mounted on one end of the connecting plate 201 via the connecting bolt 102, and a push rod 202 is mounted on the other end. A rotating hole 203 is provided at the center of the connecting plate 201, and a thrust bearing 6 is provided on the rotating hole 203. The mounting column 301 is rotatably mounted on the rotating hole 203 via the thrust bearing 6. During the rotation of the rotating component 1 and the pushing component 2, the guide rod 303 will be relative to the pushing component 2 through the thrust bearing 6, so that the rotation of the pushing component 2 will not affect the guide rod 303, and the guide rod 303 is fixed relative to the pin. In addition, a fixing nut 7 is included. The end of the mounting column 301 extends out of the thrust bearing 6 and is provided with a threaded surface. The fixing nut 7 is threaded onto the threaded surface of the end of the mounting column 301. The fixing nut 7 can fix the mounting end of the mounting column 301 and prevent it from falling off during operation. Multiple stops 402 are sequentially arranged along the circumference of the outer ring surface of the slide hammer 4. A pushing inclined surface 403 is provided on one inner side of the stop block 402. A push rod 202 is provided on the push member 2 corresponding to the position of the pushing inclined surface 403, and the end of the push rod 202 abuts against the pushing inclined surface 403. During the rotation of the push member 2, the push rod 202 will slide along the pushing inclined surface 403, causing the slide hammer 4 to slide towards the spring 5 and compress the spring 5. When the push rod 202 rotates to the end face of the stop block 402, it will disengage from the stop block 402, so that the slide hammer 4 is no longer abutted by the push rod 202, and the elastic force of the spring 5 is released, pushing the slide hammer 4 to impact the impact seat 302. The impact force generates a certain tension on the pin connected to the end of the threaded joint 304.

[0028] Example 2

[0029] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, an automatic sliding hammer puller for disassembling pins using a six-sided top press includes a sliding rod 3 and a sliding hammer 4, as well as a rotating component 1. The sliding rod 3 is integrally formed from left to right with a mounting post 301, an impact seat 302, a guide rod 303, and a threaded joint 304. A limit block 8 is mounted on the threaded joint 304, and the threaded joint 304 extends beyond the limit block 8 and is threaded onto the pin. It also includes a mounting nut 9, which secures the limit block 8 to the threaded joint 304. The guide rod 303 is fitted with the sliding hammer 4 and a spring 5. One end of the spring 5 abuts against the sliding hammer 4, and the other end abuts against the limit block 8. The sliding hammer 4 elastically abuts against the impact seat 302 via the spring 5. The sliding hammer 4 also includes an impact head 404, which is fitted to the impact seat 302 at the end face where the sliding hammer 4 abuts. The guide rod 303 includes a guide plate 305. The guide plate 305 is symmetrically arranged on the side of the guide rod 303 along its length direction. The sliding hammer 4 has a sliding hole 401 that matches the guide rod 303 at its center position. The sliding hammer 4 is slidably mounted on the guide rod 303 through the sliding hole 401.

[0030] like Figures 2-6 As shown, one end of the rotating component 1 is provided with a rotating chuck 101, which has a three-sided flat structure for connecting external power tools. The rotating chuck 101 has three flat sides arranged sequentially along its circumference, which can be adapted to the three-jaw chuck of existing electric drills. The electric drill can clamp the rotating chuck 101 through the chuck, causing it to rotate. Operation is simple and convenient, and it is easy to select the rotating tool. The other end is detachably provided with a pusher 2, on which a mounting post 301 is rotatably mounted. The rotating component 1 also includes a connecting bolt 102. The pusher 2 includes a connecting plate 201. The rotating component 1 is mounted on one end of the connecting plate 201 via the connecting bolt 102, and a push rod 202 is mounted on the other end. A rotating hole 203 is opened at the center of the connecting plate 201, and a thrust bearing 6 is provided on the rotating hole 203. The mounting post 301 is rotatably mounted on the rotating hole 203 via the thrust bearing 6. Additionally, a fixing nut 7 is included. A thrust bearing 6 extends from the end of the mounting post 301 and is provided with a threaded surface. The fixing nut 7 is threaded onto the threaded surface at the end of the mounting post 301. Multiple stops 402 are sequentially arranged on the outer ring surface of the sliding hammer 4 along its circumference. A pushing inclined surface 403 is provided on one inner side of the stop 402. Push rods 202 are provided on the push members 2 at positions corresponding to the pushing inclined surface 403, and the ends of the push rods 202 abut against the pushing inclined surface 403.

[0031] The working principle of this utility model is as follows: In use, the sliding rod 3 is installed on the pin through the threaded joint 304 at the end of the sliding rod 3, and then clamped on the rotating chuck 101 by an external power tool, which drives the rotating part 1 to rotate. The rotating part 1 drives the pushing part 2 to rotate. During the rotation of the pushing part 2, the push rod 202 slides along the pushing inclined surface 403 and gradually pushes the sliding hammer 4 to slide on the guide rod 303, which compresses the spring 5. When the push rod 202 moves to the end face of the stop block 402, it will disengage from the stop block 402. Then the sliding hammer 4 releases its elastic force through the compressed spring and hits the impact seat 302. The impact force generated by the collision between the sliding hammer 4 and the impact seat 302 will move the sliding rod 3 backward and gradually pull out the pin.

[0032] In summary, this utility model, by setting a pusher 2 on the rotating part 1, pushes the slide hammer 4, causing the slide hammer 4 to compress the spring 5 to a fixed distance. Then, the elastic release of the spring 5 pushes the slide hammer 4 to impact the impact seat 302, ensuring that the force of each impact is the same, thereby ensuring that the tension on the pin is the same each time. At the same time, by replacing the spring 5 with one of different elasticity, the impact force can be controlled to avoid excessive force causing damage to the workpiece. Moreover, it eliminates the need for manual sliding of the slide hammer to impact, reducing the difficulty of operation for workers. By setting a stop 402 with a pushing inclined surface 403 on the slide hammer 4, the slide hammer 4 can be moved by sliding the push rod 202 on the pushing inclined surface 403, which is simple and convenient.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
