Description

Technical Field

[0001] The present invention relates to the technical field of gasket press-fitting, and in particular to a press-fitting device and method for gasket assembly. Background Art

[0002] Gasket press-fitting is a critical process in mechanical assembly to ensure joint tightness and functionality. Its core is to tightly bond the gasket to the nut and workpiece by applying controlled pressure, balancing the requirements of anti-loosening, sealing, pressure distribution, and material protection. The gasket is inserted into the nut and initially positioned on the bolt or workpiece. Press-fitting is achieved through direct or rotary pressure. Direct pressure is suitable for soft gaskets (such as rubber and copper) or high-precision sealing applications, where vertical pressure is applied to ensure an even fit. Rotary pressure is used for hard gaskets or when thread deviation needs to be corrected, improving engagement and stress distribution through rotary pressure.

[0003] During the press-fitting process of the gasket, the workpiece to be pressed usually needs to be pre-lubricated before continuing the press-fitting to ensure smoothness of the press-fitting process. At the same time, the pressure-bearing area on the top of the gasket needs to be manually cleaned before press-fitting to avoid foreign matter in the pressure-bearing area of ​​the gasket causing damage to the gasket, resulting in a decrease in the overall press-fitting efficiency.

[0030] Reference Figures 1 to 5 , which is the first embodiment of the present invention, provides a press-fitting method of a press-fitting device for gasket assembly to achieve lubrication and cleaning.

[0031] The press-fitting mechanism 100 is activated to press downward, thereby press-fitting the gasket onto the workpiece; During the downward installation process, the jet mechanism 200 is squeezed, so that the jetted gas is blown away foreign matter on the gasket surface, thereby preventing the gasket surface from being dented due to the press-fitting when there is foreign matter on the gasket surface. During the jetting process, the lubricating mechanism 300 will discharge part of the lubricating liquid, and the discharged part of the lubricating liquid will be carried out by the airflow ejected by the jetting mechanism 200 and sprayed on the pressing part of the workpiece, ensuring that the pressing part is sufficiently lubricated and improving processing efficiency. Example 2

[0032] Reference Figures 1-3 5 is a second embodiment of the present invention, which provides a press-fitting mechanism 100 and an air-jet mechanism 200 to achieve air-jet cleaning during the press-fitting of the gasket or cooling when press-fitting the gasket made of heat-sensitive material.

[0033] The press-fitting mechanism 100 includes a press-fitting frame 101, a press-fitting seat 102 is fixedly connected to the bottom of the inner wall of the press-fitting frame 101, a cylinder 103 is fixedly connected to the top of the press-fitting frame 101, and the piston end of the cylinder 103 passes through the interior of the press-fitting seat 102 and is fixedly connected to a press-fitting sleeve 104; the jet mechanism 200 includes a mounting plate 201, the mounting plate 201 is sleeved on the surface of the press-fitting sleeve 104, and both sides of the bottom of the mounting plate 201 are fixedly connected to air bags 202, the bottom of the air bags 202 are fixedly connected to both sides of the bottom of the inner wall of the press-fitting frame 101, and the inside of the press-fitting sleeve 104 is fixedly connected to the inner wall of the press-fitting frame 101. The bottom is fixedly connected to a jet ring 203, the top of the airbag 202 is connected to a jet one-way valve 204, the airbag 202 is connected to the jet ring 203 through the jet one-way valve 204, the bottom of the outer side of the airbag 202 is connected to an air intake one-way valve 205, the front and rear sides of the bottom of the inner wall of the press-fitting sleeve 104 are movably connected to the limit strip 206, the top of the limit strip 206 passes through the top of the mounting plate 201 and is slidably connected to the mounting plate 201, the top of the limit strip 206 is fixedly connected to the top of the inner wall of the press-fitting frame 101, and a loading port 105 is provided on the back of the press-fitting frame 101.

[0034] Specifically, the cylinder 103 is started to drive the pressing sleeve 104 to press the gasket on the workpiece onto the surface of the workpiece. During the pressing process, the airbag 202 is squeezed and sprays air downward to clean the surface of the gasket where it is pressed, to avoid the presence of some foreign matter causing the top of the gasket to be concave when the gasket is under pressure.

[0035] Furthermore, when press-fitting is required, after placing the workpiece and the gasket on the press-fitting seat 102, the user activates the cylinder 103 to drive the press-fitting sleeve 104 to move downward, thereby press-fitting the gasket on the workpiece to the surface of the workpiece. At the same time, if a loading device is required, the user can load the top of the press-fitting sleeve 104 by installing the loading device to be installed at the loading port 105 position opened on the press-fitting frame 101. During the process of the press-fitting sleeve 104 moving downward for press-fitting, the press-fitting sleeve 104 will synchronously drive the mounting plate 201 to move downward, so that the mounting plate 201 drives the top of the airbag 202 to press downward, and then the air inside the airbag 202 will be sprayed into the inside of the jet ring 203 through the jet check valve 204 and pass through the jet ring 2 03 sprays air downward, and the sprayed air flow will blow to the top of the gasket, thereby jetting and cleaning the surface of the gasket at the pressure point, avoiding the presence of some foreign matter causing the gasket to be dented when it is under pressure, and when the airbag 202 is pressed down, the sliding connection between the limiting strip 206 and the mounting plate 201 can limit the inner side of the airbag 202, avoiding the airbag 202 from deforming inward when compressed by downward pressure, thereby affecting the press-fitting of the gasket. After the press-fitting is completed, when the cylinder 103 drives the press-fitting sleeve 104 to move upward, the mounting plate 201 will move upward, causing the airbag 202 to be deployed, and then the outside gas will enter the airbag 202 through the air inlet one-way valve 205 for replenishment, so as to facilitate the next use. Example 3

[0036] Reference Figures 1 to 5 , which is the third embodiment of the present invention, provides a lubrication mechanism 300 to achieve lubrication during the press-fitting process, thereby improving the press-fitting efficiency. When press-fitting gaskets made of heat-sensitive materials, the lubricating liquid can be replaced with a coolant.

[0037] The lubricating mechanism 300 includes a liquid storage box 301, in which lubricating liquid is stored. The top of the liquid storage box 301 is fixedly connected to the top of the inner wall of the press-fitting sleeve 104. Both sides of the bottom of the liquid storage box 301 are provided with drain holes 302, which are connected to the jet ring 203. The inside of the drain hole 302 is slidably connected to a sealing block 303. The bottom of the liquid storage box 301 is provided with a transmission plate 304. The front and rear sides of the bottom of the transmission plate 304 are fixedly connected to the top of the sealing block 303. The bottom of the transmission plate 304 is fixedly connected to a transmission member 305. The bottom of the transmission member 305 passes through the bottom of the liquid storage box 301. The bottom of the jet ring 203 is fixedly connected to an atomizing mesh ring 306. The top and bottom of the front of the liquid storage box 301 are both connected to a liquid replacement component 307. The liquid replacement component 307 includes a liquid replacement tube 307a. The liquid replacement tube 307 The back of a is connected to the top and bottom of the front of the liquid storage box 301, and the front side of the liquid exchange tube 307a is threadedly connected to a sealing sleeve 307b, and the surface of the sealing sleeve 307b is provided with an anti-slip groove 307c. Both sides of the top of the transmission plate 304 are fixedly connected to a return spring 308, and the other end of the return spring 308 is fixedly connected to both sides of the top of the inner wall of the liquid storage box 301. Both sides of the bottom of the inner wall of the liquid storage box 301 are fixedly connected to a limit rod 309, and the top of the limit rod 309 passes through the top of the transmission plate 304 and is slidably connected to the transmission plate 304. The top of the limit rod 309 is fixedly connected to both sides of the top of the inner wall of the liquid storage box 301, and the transmission plate 304 is arranged in a cross shape. The bottom of the sealing block 303 is fixedly connected to a frustum block 310. The diameter of the top of the frustum block 310 is larger than the diameter of the bottom, and the frustum block 310 is located inside the liquid discharge hole 302.

[0038] Specifically, when the press-fitting sleeve 104 moves downward and approaches the workpiece, part of the lubricating liquid will be discharged and sprayed out by the power of the airflow. The lubricating liquid will be separated into mist and sprayed out through the atomizing mesh ring 306, and the atomized lubricating liquid can be evenly distributed on the workpiece and the inner side of the gasket, thereby ensuring that the gasket is pressed smoothly enough and improving the pressing efficiency.

[0039] Furthermore, when the press-fitting sleeve 104 moves downward and approaches the workpiece, the transmission member 305 below the press-fitting sleeve 104 first contacts the workpiece, and then the transmission member 305 is subjected to force and moves upward, and then the transmission member 305 drives the transmission plate 304 to move upward along the path on the surface of the limiting rod 309, thereby pulling the sealing block 303 and the frustum block 310 out of the liquid drain hole 302, and then the lubricating liquid in the liquid storage box 301 flows into the inside of the jet ring 203 through the liquid drain hole 302, and at the same time, the characteristic that the top diameter of the frustum block 310 is larger than the bottom diameter is utilized, so that the frustum block 310 gradually moves upward. During the movement, the displacement of the lubricating liquid increases from small to large, avoiding the waste of lubricating liquid caused by directly discharging too much lubricating liquid. During this period, the jet ring 203 is continuously in the jet state, and the lubricating liquid flowing into the jet ring 203 will be sprayed out by the power of the air flow, and the lubricating liquid will be separated into mist and sprayed out through the atomizing mesh ring 306. The atomized lubricating liquid can be evenly distributed on the workpiece and the inner side of the gasket, thereby ensuring that the gasket is press-fitted smoothly and improving the press-fitting efficiency. After the press-fitting is completed, when the press-fitting sleeve 104 is subjected to force and moves upward to reset, the transmission member 305 will be separated from the workpiece, and then The elastic force of the spring will be released and drive the transmission piece 304 to move downward and reset, so that the frustum block 310 and the sealing block 303 are driven by the transmission piece 304 to reset to the inside of the liquid discharge hole 302 for sealing. At the same time, the transmission piece 304 is arranged in a cross shape, so that the transmission piece 304 does not affect the liquid discharge during the transmission process. When the gasket of some soft or heat-sensitive materials is press-fitted, the gasket will heat up during the press-fitting process, making the gasket prone to plastic deformation. At this time, the sealing sleeve 307b below is pinched by the anti-slip groove 307c and rotated, so that the sealing sleeve 307b and the liquid exchange tube 307b are in contact with each other. 07a is detached, and then the lubricating liquid stored in the liquid storage box 301 can be discharged through the liquid exchange tube 307a below. After the discharge is completed, it is sealed, and the upper sealing sleeve 307b is screwed down, and the coolant is added to the liquid storage box 301 through the upper liquid exchange tube 307a for use, and the corresponding sealing sleeve 307b is installed and sealed, so that the step of spraying lubricating oil in the original process is changed to spraying coolant, and the mist-like coolant is sprayed on the inside of the workpiece and the gasket to assist cooling. At the same time, the airflow sprayed by the airbag 202 can also improve the cooling effect of the coolant on the workpiece and the gasket.

[0040] It should be noted that the liquid storage box 301 is made of transparent acrylic, and the surface of the press-fit sleeve 104 has an opening. The level of the internal liquid can be clearly observed through the opening and the transparent liquid storage box 301, which is convenient for users to add liquid in time.

[0041] The remaining structures are the same as those of Example 2. Example 4

[0042] Reference Figures 1 to 5, which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a press-fitting device and method for gasket assembly.

[0043] When press-fitting is required, after placing the workpiece and the gasket on the press-fitting seat 102, the user activates the cylinder 103 to drive the press-fitting sleeve 104 to move downward, thereby press-fitting the gasket on the workpiece onto the surface of the workpiece. At the same time, if a loading device needs to be installed, the user can load the top of the press-fitting sleeve 104 by installing the loading device to be installed at the loading port 105 opened on the press-fitting frame 101.

[0044] During the process of the press-fitting sleeve 104 moving downward for press-fitting, the press-fitting sleeve 104 will synchronously drive the mounting plate 201 to move downward, so that the mounting plate 201 drives the top of the airbag 202 to press downward, and then the air inside the airbag 202 will be sprayed into the inside of the jet ring 203 through the jet check valve 204 and sprayed downward through the jet ring 203. The sprayed air will blow to the top of the gasket, thereby jet cleaning the surface of the gasket where it is pressed, to avoid the presence of some foreign matter causing the top of the gasket to be concave when the gasket is pressed. When the airbag 202 is pressed down, the inner side of the airbag 202 can be limited by the sliding connection between the limit bar 206 and the mounting plate 201, so as to prevent the airbag 202 from deforming inward when compressed by downward pressure, thereby affecting the press-fitting of the gasket. After the press-fitting is completed, when the cylinder 103 drives the press-fitting sleeve 104 to move upward, the mounting plate 201 will move upward, causing the airbag 202 to be deployed, and then the outside gas will enter the airbag 202 through the air inlet one-way valve 205 for replenishment, so as to facilitate the next use.

[0045] When the press-fitting sleeve 104 moves downward and approaches the workpiece, the transmission member 305 below the press-fitting sleeve 104 first contacts the workpiece, and then the transmission member 305 is subjected to force and moves upward, and then the transmission member 305 drives the transmission plate 304 to move upward along the path on the surface of the limit rod 309, thereby pulling the sealing block 303 and the frustum block 310 out of the liquid drain hole 302, and then the lubricating fluid in the liquid storage box 301 will flow into the inside of the jet ring 203 through the liquid drain hole 302. At the same time, the characteristic that the top diameter of the frustum block 310 is larger than the bottom diameter is utilized, so that the displacement of the lubricating fluid increases from small to large during the gradual upward movement of the frustum block 310, thereby avoiding direct discharge of excessive lubricating fluid and causing waste of lubricating fluid. During this period, the jet ring 203 is continuously in In the jet state, the lubricating liquid flowing into the jet ring 203 will be sprayed out by the power of the air flow, and the lubricating liquid will be separated into mist and sprayed out through the atomizing mesh ring 306, and the atomized lubricating liquid can be evenly distributed on the workpiece and the inner side of the gasket, thereby ensuring that the gasket is press-fitted smoothly and improving the press-fitting efficiency. After the press-fitting is completed, when the press-fitting sleeve 104 is subjected to force and moves upward to reset, the transmission member 305 will be separated from the workpiece, and then the elastic force of the spring will be released and drive the transmission plate 304 to move downward to reset, so that the frustum block 310 and the sealing block 303 are driven by the transmission plate 304 to reset to the inside of the liquid discharge hole 302 for sealing. At the same time, the transmission plate 304 is arranged in a cross shape, so that the transmission plate 304 does not affect the liquid discharge during the transmission process.

[0046] When press-fitting gaskets made of some soft or heat-sensitive materials, the gaskets will heat up during the press-fitting process, making them prone to plastic deformation. At this time, the anti-slip groove 307c is used to pinch the lower sealing sleeve 307b and rotate it, so that the sealing sleeve 307b is separated from the liquid exchange tube 307a, and then the lubricating fluid stored in the liquid storage box 301 can be discharged through the lower liquid exchange tube 307a. After the discharge is completed, it is sealed and the upper sealing sleeve 307b is rotated and unscrewed, and the coolant is added to the liquid storage box 301 through the upper liquid exchange tube 307a for use, and the corresponding sealing sleeve 307b is installed and sealed, so that the step of spraying lubricating oil in the original process is changed to spraying coolant. The mist-like coolant is sprayed on the workpiece and the inside of the gasket to assist cooling. At the same time, the airflow sprayed by the airbag 202 can also improve the cooling effect of the coolant on the workpiece and the gasket.

[0047] In summary, the pressing mechanism 100 is started to press down, and the jet mechanism 200 is started to produce extrusion, and gas is sprayed to blow away foreign matter on the surface of the gasket, so as to avoid depression on the surface of the gasket caused by pressing when there are foreign matter on the surface of the gasket. At the same time, the lubricating mechanism 300 will discharge part of the lubricating fluid and spray it on the pressing part of the workpiece under the power of the airflow to ensure that the pressing part is sufficiently lubricated.
