Description

Technical Field

[0001] The utility model belongs to the technical field of parts disassembly, and in particular relates to a quick disassembly and assembly mechanism. Background Art

[0002] At present, the installation and disassembly of bearings in equipment, the installation and disassembly of locating pins in equipment, the installation and disassembly of core shafts in equipment, etc., are all purely manual work without the assistance of professional tools. Due to the different professional qualities of assembly fitters, the installed machines will be very different.

[0003] Therefore, in order to avoid the adverse effects of this purely manual work, a slide hammer is used for disassembly and assembly. This type of auxiliary tooling can reduce the uneven professional level of manual work and solve the problem that the machine installation varies greatly. However, the slide hammer mechanism of the prior art has a large impact force and often results in rough installation, which affects the installation of the equipment. Utility Model Content

[0004] The utility model aims to provide a quick disassembly and assembly mechanism to solve the technical problem that the sliding hammer mechanism in the prior art has a large impact force and often leads to rough installation, which affects the installation of the equipment.

[0005] In order to solve the above technical problems, the utility model provides a quick disassembly and assembly mechanism, which does not provide a particularly large installation force, but can provide a large disassembly force during disassembly, thereby improving the standardization of installation or disassembly operations, is simple to operate, and saves time and effort.

[0006] The utility model provides a quick disassembly and assembly mechanism, comprising:

[0007] A handle, a pull rod, a sliding hammer and a conversion joint, wherein the handle and the conversion joint are respectively arranged at both ends of the pull rod, and the conversion joint is used to connect the mechanism to be disassembled or installed, and the sliding hammer is sleeved on the pull rod, and the sliding hammer can slide back and forth along the pull rod. When disassembling, the sliding hammer slides toward one end of the handle and hits the handle to provide a disassembly force, and when installing, the sliding hammer slides toward one end of the conversion joint and hits the conversion joint to provide an installation force;

[0008] Assume that the cross section of the slide hammer perpendicular to the pull rod direction is S, and the cross section S increases continuously along the direction from the conversion joint to the handle.

[0009] The quick disassembly and assembly mechanism of the utility model has the advantages that during installation, the sliding hammer is manually slid toward the conversion joint to hit the conversion joint, and since the end face of the sliding hammer facing the conversion joint is set to be smaller, the impact force generated between the two will not be too large, and therefore the provided installation force will not be too large, thereby avoiding rough installation by the installers and improving the standardization of the installation work; during disassembly, the sliding hammer is manually slid toward the handle to hit the handle, and since the end face of the sliding hammer facing the handle is set to be larger, the impact force between the two will be larger, and therefore the provided disassembly force will be larger, thereby ensuring that a larger disassembly force can be provided during disassembly and facilitating disassembly.

[0010] Furthermore, in order to facilitate manual holding of the sliding hammer, the sliding hammer is in the shape of a cone, and a plurality of arc grooves are arranged on the circumference of the sliding hammer. The plurality of arc grooves can increase the friction during the holding process and facilitate pushing the sliding hammer. In order to facilitate use, the plurality of arc grooves are distributed at intervals.

[0011] Furthermore, in order to increase the disassembly force while preventing impact on the hand, the handle includes a hand-holding portion and a stop portion, wherein the stop portion is arranged at the connection between the hand-holding portion and the pull rod, and the stop portion is used to stop the impact of the slide hammer.

[0012] Furthermore, the stop portion is a step surface, the small end surface of the step surface faces the sliding hammer, and the large end surface of the step surface faces the hand-held portion, further preventing the hand from being hit due to misoperation.

[0013] Furthermore, in order to reduce the packaging size and facilitate carrying, the pull rod includes a plurality of rod bodies, and the plurality of rod bodies can be detachably connected.

[0014] Furthermore, to facilitate installation, adjacent rods are connected by threads or snaps.

[0015] Furthermore, in order to facilitate connection, one end of the conversion joint is threadedly connected to the pull rod, and the other end of the conversion joint matches the mechanism to be disassembled or installed.

[0016] Furthermore, in order to facilitate connection, the pull rod is connected to the handle via threads.

[0017] Furthermore, in order to facilitate holding, the handle is made of rubber, and anti-slip patterns are provided on the peripheral surface of the handle.

[0018] The beneficial effects of the utility model are:

[0019] The quick disassembly and assembly mechanism of the utility model has the advantages that during installation, the sliding hammer is manually slid toward the conversion joint to hit the conversion joint, and since the end face of the sliding hammer facing the conversion joint is set to be smaller, the impact force generated between the two will not be too large, and therefore the provided installation force will not be too large, thereby avoiding rough installation by the installers and improving the standardization of the installation work; during disassembly, the sliding hammer is manually slid toward the handle to hit the handle, and since the end face of the sliding hammer facing the handle is set to be larger, the impact force between the two will be larger, and therefore the provided disassembly force will be larger, thereby ensuring that a larger disassembly force can be provided during disassembly and facilitating disassembly.

[0020] The quick disassembly and assembly mechanism of the utility model is easy to operate and only requires one staff member for operation, which saves time and effort. The overall mechanism is simple and reasonable, and the installation and disassembly are very convenient, and it is also easy to maintain.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 4 The figure shows the best embodiment of the utility model, which provides a quick disassembly and assembly mechanism, including:

[0031] A handle 1, a pull rod 2, a sliding hammer 3 and a conversion joint 4. The handle 1 and the conversion joint 4 are respectively arranged at both ends of the pull rod 2. The conversion joint 4 is used to connect the mechanism to be disassembled or installed. The sliding hammer 3 is sleeved on the pull rod 2. The sliding hammer 3 can slide back and forth along the pull rod 2. When disassembling, the sliding hammer 3 slides toward one end of the handle 1 and hits the handle 1 to provide a disassembly force. When installing, the sliding hammer 3 slides toward one end of the conversion joint 4 and hits the conversion joint 4 to provide an installation force.

[0032] Assume that the cross section of the slide hammer 3 perpendicular to the pull rod 2 is S. Along the direction from the conversion joint 4 to the handle 1, the cross section S increases continuously, that is, the cross section S near the conversion joint 4 has the smallest area, and the cross section S near the handle 1 has the largest area.

[0033] The quick disassembly and assembly mechanism of the utility model, during installation, the sliding hammer 3 is manually slid toward the conversion joint 4 to hit the conversion joint 4. Since the end face of the sliding hammer 3 facing the conversion joint 4 is set smaller, the impact force generated between the two will not be too large. Therefore, the provided installation force will not be too large, which avoids rough installation by the installation workers and improves the standardization of the installation work. During disassembly, the sliding hammer 3 is manually slid toward the handle 1 to hit the handle 1. Since the end face of the sliding hammer 3 facing the handle 1 is set larger, the impact force between the two is larger. Therefore, the provided disassembly force is larger, which can ensure that a larger disassembly force can be provided during disassembly, and the disassembly is convenient.

[0034] like Figure 2 As shown, the slide hammer 3 is in a cone shape, and a plurality of arc grooves 31 are arranged on the circumference of the slide hammer 3. The arc grooves 31 are arranged at intervals, and the arc grooves 31 are arranged in circles on the outer circumference of the slide hammer 3. When the slide hammer 3 is pushed manually, the arc grooves 31 can effectively enhance the friction between the outer surface of the slide hammer 3 and the palm, and prevent the slide hammer 3 from slipping out of the hand and causing human damage.

[0035] like Figure 3As shown, the handle 1 includes a hand-held portion 11 and a stop portion 12. The stop portion 12 is provided at the connection between the hand-held portion 11 and the pull rod 2. The stop portion 12 is used to stop the impact of the sliding hammer 3. The stop portion 12 is a step surface, the small end surface of the step surface faces the sliding hammer 3, and the large end surface of the step surface faces the hand-held portion 11. The hand-held portion 11 is a hand-holding portion. The operator can hold the hand-held portion 11 with one hand and push the sliding hammer 3 with the other hand. When in use, the impact force of the sliding hammer 3 is increased by providing the stop portion 12, and at the same time, the sliding hammer 3 is prevented from hitting the hand. The large end surface of the step surface faces the hand-held portion 11, which further prevents the sliding hammer 3 from hitting the hand due to misoperation.

[0036] The pull rod 2 includes a plurality of rod bodies 21, and the plurality of rod bodies 21 can be detachably connected. The pull rod 2 can be a single rod, two rods spliced ​​together, or multiple rods spliced ​​together. Two or more spliced ​​pull rods can effectively reduce the packaging size and are more convenient to carry.

[0037] In order to facilitate connection and ensure connection strength, adjacent rod bodies 21 are threadedly connected or snap-fitted.

[0038] In order to facilitate connection while ensuring connection strength, one end of the conversion joint 4 is threadedly connected to the pull rod 2, and the other end of the conversion joint 4 matches the mechanism to be disassembled or installed. The other end of the conversion joint 4 can be matched with a variety of conversion joints according to the mechanism to be disassembled or installed.

[0039] In order to facilitate connection and ensure connection strength, the pull rod 2 is connected to the handle 1 through threads.

[0040] In order to facilitate holding, the handle portion 11 is made of rubber, and anti-slip patterns are arranged on the peripheral surface of the handle portion 11 .

[0041] Working principle:

[0042] like Figure 1 As shown, the conversion joint 4 is installed in the component that needs to be installed, and the small face of the slide hammer 3 hits the right side face of the conversion joint 4. The impact force generated between the two directly acts on the installed component, thereby utilizing the impact force of the slide hammer 3 on the handle 1 to complete the installation work. Since the end face of the slide hammer 3 facing the conversion joint 4 is set smaller, the impact force generated between the two will not be too large. Therefore, the provided installation force will not be too large, which avoids rough installation by the installers and improves the standardization of the installation work.

[0043] The conversion joint 4 is installed in the part that needs to be disassembled, and the large surface of the sliding hammer 3 hits the stepped surface on the left side of the handle 1. The impact force generated between the two indirectly acts on the disassembled part, so that the impact force of the sliding hammer 3 on the handle 1 is used to complete the disassembly work. Since the end surface of the sliding hammer 3 facing the handle 1 is set larger, the impact force between the two is larger. Therefore, the disassembly force provided is larger, which can ensure that a larger disassembly force can be provided during disassembly, making disassembly easier.

[0044] The quick disassembly and assembly mechanism of the utility model has the advantages mentioned above and is also simple to operate. It only requires one worker to operate, which saves time and effort. The overall structure is simple and reasonable, and it is very convenient to install and disassemble, and it is also easy to maintain.

[0045] The various devices selected in this application are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
