[0033] Transmission disassembly and inspection is an important part of sample problem analysis after transmission bench test. Meanwhile, transmission disassembly and inspection is also a basic work of automobile maintenance. The quality of disassembly and inspection will directly affect the transmission performance and the accuracy of the data of the next bench test. During transmission disassembly and inspection, snap ring pliers are often used to disassemble and assemble the earless snap rings in the transmission. However, due to the structural characteristics of the transmission clutch sleeve at the front end of the input shaft, the operating space of ordinary snap ring pliers is limited and the opening is small during use. Therefore, the clamping place of ordinary calipers and earless snap rings is easy to fall off. Repeated falling off will cause the earless snap rings to deform and be damaged.

[0034] Based on this, please refer to Figure 1 and Figure 2 The disassembly and assembly device 1000 provided in the embodiment of the utility model can solve the above-mentioned technical problems. The disassembly and assembly device 1000 is applied to the disassembly and assembly of the earless snap ring in the automobile transmission, and can open the earless snap ring in a small space, making it easy to disassemble from the transmission and assemble into the transmission.

[0035] Figure 1 A schematic diagram of a disassembly device provided in an embodiment of the utility model from a first viewing angle; Figure 2This is a schematic diagram of a disassembly device provided in an embodiment of the present utility model from a second viewing angle, as shown in FIG. Figure 1 and Figure 2 As shown, the disassembly and assembly device 1000 includes a housing 100 and a support structure 200. The housing 100 has a housing cavity 110. A buckle 120 is provided at one end of the housing 100. The buckle 120 is used to be sleeved with the earless buckle. The inner diameter of the housing cavity 110 gradually decreases along the direction close to the buckle 120. The support structure 200 includes a moving component 210 and a support part 220. One end of the moving component 210 is connected to the support part 220. The moving component 210 is used to drive the support part 220 to move in the housing cavity 110, and the housing 100 is supported in the process of approaching one end of the buckle 120 to tighten the earless buckle. The diameter of the shell 100 is the same as the diameter of the earless snap ring. In order to facilitate the shell 100 to deform slightly, the shell 100 is made of rubber or other materials with a certain hardness and slight deformation. The shell 100 can support the earless snap ring while being expanded by the expansion structure 200 to tension the earless snap ring.

[0036] By using the housing 100, the earless snap ring is sleeved on the buckle 120 of the housing 100, and the expansion structure 200 is arranged in the housing 100. The expansion structure 200 can move in the accommodating cavity 110 of the housing 100, and expand the housing 100 in the process of approaching one end of the buckle 120 to tighten the earless snap ring. The earless snap ring is sleeved on the housing 100 to prevent the snap ring from falling off, and the earless snap ring can be expanded in a small space, which is convenient for assembling and disassembling the earless snap ring.

[0037] See also Figure 1 and Figure 2 The moving assembly 210 in this embodiment includes a fixing frame 211 and a screw 212. The fixing frame 211 is provided with a threaded hole. The screw 212 is connected to the fixing frame 211 through the threaded hole. The fixing frame 211 is connected to the housing 100. One end of the screw 212 is connected to the opening portion 220. The screw 212 can rotate and move relative to the fixing frame 211 to drive the opening portion 220 to move relative to the accommodating chamber 110. Of course, other linear moving structures can also be used to form the moving assembly 210, such as a ball screw, a driving member, a moving rod and other moving structures, as long as they can push the support portion to move in the accommodating chamber 110 so that the support portion opens the housing 100 to tighten the earless clamping ring, and no limitation is made here. Since the earless clamp is circular, the housing 100 in this embodiment is also a cylindrical structure. In order to cooperate with the accommodating cavity 110 and facilitate the movement of the expansion part 220 in the accommodating cavity 110, the expansion part 220 in this embodiment is a sphere, and the diameter of the sphere is the same as the maximum inner diameter of the accommodating cavity 110. Of course, the expansion part 220 can also be other regular or irregular shapes, as long as it can expand the housing 100 to a small extent, and it is not limited here.

[0038] In order to facilitate the earless buckle to be mounted on the housing 100 through the buckle 120 and simplify the structure of the entire disassembly and assembly device 1000, please refer to Figure 1 In this embodiment, the buckle 120 is a protrusion, and the earless buckle ring is sleeved into the protrusion. In addition, the buckle 120 structure can also be other shapes, as long as it is convenient for the earless buckle ring to be sleeved into the housing 100, which is not limited here.

[0039] To slightly expand the housing 100, please continue to refer to Figure 1 and Figure 2 In this embodiment, the housing 100 is composed of two detachable parts, including a first housing 130, a second housing 140 and a connecting member 150. The first housing 130 and the second housing 140 are rotatably connected through the connecting member 150, and the first housing 130 and the second housing 140 together form a receiving chamber 110; the connecting member 150 is movably connected to the moving assembly 210 along the direction of the rotation axis; the direction of the rotation axis is the extension direction of the connecting member 150 along the housing 100. In this embodiment, the first housing 130 and the second housing 140 are both semicircular bodies. When the earless snap ring needs to be disassembled and assembled, the first housing 130 and the second housing 140 rotate around the direction of the rotation axis of the connecting member 150 to contact and form a complete cylinder. The earless snap ring is sleeved on the complete cylinder formed by the first shell 130 and the second shell 140. The moving component 210 drives the expansion part 220 to move in the accommodating cavity jointly formed by the first shell 130 and the second shell 140, and in the process of approaching one end of the buckle 120, the first shell 130 and the second shell 140 are slightly separated to tighten the earless snap ring, which is convenient for removing the earless snap ring from the transmission and also convenient for installing the earless snap ring on the transmission.

[0040] Since the opening portion 220 needs to slightly open the housing 100 through the action of force, the inner diameter of the accommodating cavity 110 in the housing 100 cannot be completely consistent, and the inner diameter of some places needs to be smaller than the size of the opening portion 220. If it is necessary to process the housing 100 with a gradually decreasing inner diameter of the accommodating cavity 110, it is necessary to increase the processing time and the processing cost. In order to facilitate the processing of the housing 100 and reduce the processing time, in this embodiment, by setting a tapered sleeve in the housing 100, the inner diameter of the accommodating cavity 110 can be gradually reduced along the direction of one end close to the buckle 120.

[0041] Specifically, see Figure 1 and Figure 2In this embodiment, a first conical sleeve 160 is arranged in the first shell 130, and the first shell 130 includes a first extension portion 131 and a first guide portion 132. The first conical sleeve 160 is arranged on the side of the first extension portion 131 away from the connection with the moving component 210, and the first guide portion 132 is connected to an end of the first extension portion 131 close to the first conical sleeve 160, and a first buckle 133 is arranged on the end of the first guide portion 132 away from the first conical sleeve 160; a second conical sleeve 170 is arranged in the second shell 140, and the second shell The housing 140 includes a second extension portion 141 and a second guide portion 142. A second conical sleeve 170 is provided on the side of the second extension portion 141 away from the connection with the moving assembly 210. The second guide portion 142 is connected to an end of the second extension portion 141 close to the second conical sleeve 170. A second buckle 143 is provided on an end of the second guide portion 142 away from the second conical sleeve 170. The first conical sleeve 160 and the second conical sleeve 170 together form a conical surface. The first buckle 133 and the second buckle 143 cooperate to set an earless buckle ring. By setting the conical sleeve, the housing 100 can be processed normally. The first housing 130 is processed into a semicircular body with the same inner diameter throughout the entire length, and the second housing 140 is processed into a semicircular body with the same inner diameter throughout the entire length. The first conical sleeve 160 is provided in the first housing 130, and the second conical sleeve 170 is provided in the second housing 140, so that the inner diameter of the first housing 130 and the second housing 140 close to the buckle 120 can be reduced.

[0042] In order to enhance the structural strength of the connector 150, please continue to refer to Figure 1 and Figure 2 In this embodiment, the connecting member 150 includes a connecting shaft 151 and two collars 152. The two collars 152 connect the first housing 130 and the second housing 140. The first housing 130 and the second housing 140 can rotate relative to the collars 152. The two collars 152 are connected by the connecting shaft 151. By adding the connecting shaft 151 between the two collars 152, the structural strength of the collars 152 can be increased, and the service life of the disassembly and assembly device 1000 can be extended.

[0043] See also Figure 3 , Figure 3This is a schematic diagram of the disassembly device provided in the embodiment of the utility model from a third perspective. During installation, in the initial state, when the earless snap ring is inserted into the shell 100, the shell 100 is not in an open state. In order to prevent the earless snap ring from slipping out of the buckle 120 structure of the shell 100 during installation, in this embodiment, an adhesive member 180 is provided at one end of the shell 100 close to the small inner diameter of the accommodating cavity 110. The adhesive member 180 is used to make the earless snap ring close to the shell 100. In this embodiment, the adhesive member 180 is a magnetic patch. Because the earless snap ring is made of metal, the earless snap ring can be adsorbed on the shell 100 by using a magnetic patch. In addition, the magnetic force of the magnetic patch is not large, which is convenient for installing the earless snap ring. In addition, the structure of the earless snap ring can be not affected by the magnetic attraction. Of course, the adhesive member 180 may also be glue with weak bonding strength, as long as the earless clamp can be attached to the housing 100 during installation, and can be detached from the housing 100 and installed into the transmission after installation, the specific adhesive member 180 used is not limited here.

[0044] According to a disassembly and assembly device 1000 provided in this embodiment, its working principle is as follows:

[0045] When disassembling the earless snap ring, first place the transmission disassembly sample horizontally on the disassembly platform, remove the clutch oil plug, and place the earless snap ring opening downward. Push the disassembly device 1000 horizontally into the clutch sleeve on the input shaft, and ensure that the buckle 120 is in the opening of the earless snap ring. Since the end of the housing with the buckle 120 is provided with a magnetic patch, the earless snap ring is tightly attached to the housing 100 under the action of magnetic force. Then, use an open-end wrench to rotate and push the screw 212, and push the screw 212 to drive the expansion part 220 to move forward together. The expansion part 220 moves forward and contacts with the tapered sleeve. During the forward movement of the expansion part 220, the expansion of the tapered sleeve is expanded, and then the housing 100 is expanded, so that the buckle 120 of the housing 100 is in contact with the two open end faces of the earless snap ring to tighten, and the earless snap ring is expanded. Finally, the disassembly device 1000 is pulled out axially outward with force, driving the earless snap ring to be pulled out together, and the snap ring is disassembled.

[0046] When installing the earless snap ring, first place the transmission sample horizontally on the disassembly and inspection platform, select a suitable earless snap ring, and set the earless snap ring sleeve into one end of the housing 100 with a magnetic patch, ensuring that the buckle 120 is in the opening of the earless snap ring. Under the action of the magnetic force, ensure that the earless snap ring is adsorbed on the front end of the housing 100 of the device. Then, use an open-end wrench to rotate and push the screw rod 212, and push the screw rod 212 to drive the expansion part 220 to move forward together. The expansion part 220 moves forward and contacts with the tapered sleeve. During the forward movement of the expansion part 220, the expansion tapered sleeve expands outward, and then drives the housing 100 to expand outward, so that the buckle 120 and the two open end faces of the earless snap ring are in contact and tensioned, and the snap ring is expanded, and the snap ring opening is expanded to a size slightly larger than the outer diameter of the input shaft, which is suitable for installation. Next, the device is horizontally inserted onto the input shaft, and inserted into the position where the snap ring and the shaft match. The screw rod 212 is rotated and pushed with an open-end wrench, and the screw rod 212 drives the expansion part 220 to move backward together, and the expansion part 220 moves backward to contact and match with the tapered sleeve. During the backward movement of the expansion part 220, the opening of the tapered sleeve is reduced under the elastic force of the earless snap ring, so that the opening of the earless snap ring is reduced and stuck in the groove matching with the input shaft. Finally, the installation status of the earless snap ring is checked to complete the installation of the earless snap ring.

[0047] In summary, the disassembly and assembly device 1000 includes a housing 100 and a support structure 200. The housing 100 has a receiving cavity. A buckle 120 is provided at one end of the housing 100. The buckle 120 is used to be sleeved with the earless buckle. The inner diameter of the receiving cavity 110 gradually decreases along the direction of the end close to the buckle 120. The support structure 200 includes a moving component 210 and a support portion 220. One end of the moving component 210 is connected to the support portion 220. The moving component 210 is used to drive the support portion 220 to move in the receiving cavity, and in the process of approaching one end of the buckle 120, the housing 100 is supported to be stretched to tighten the earless buckle. By using the housing 100, the earless snap ring is sleeved on the buckle 120 of the housing 100, and the expansion structure 200 is arranged in the housing 100. The expansion structure 200 can move in the accommodating cavity 110 of the housing 100, and expand the housing 100 in the process of approaching one end of the buckle 120 to tighten the earless snap ring. The earless snap ring is sleeved on the housing 100 to prevent the snap ring from falling off, and the earless snap ring can be expanded in a small space, which is convenient for assembling and disassembling the earless snap ring.

[0048] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
