Description

Technical Field

[0001] The present invention relates to the field of press-fitting technology, and in particular to a cabin press-fitting mechanism. Background Art

[0002] With the development of press-fitting technology, the press-fitting methods of shaft and sleeve products are constantly updated. From the initial pure manual to the current electrical drive, they have been widely developed and applied to the press-fitting devices of products. Mature product cases include motor rotors, gear-core shaft matching, locomotive bogie axle box tie rods, core components, etc. From the perspective of manufacturing and process, how to ensure its assembly relationship, assembly quality and assembly efficiency is an important issue. Application No. CN201420426953.X discloses a workpiece press-fitting device that effectively controls the verticality of the core shaft; Application No. CN202320572676.2 discloses a rotary feeding core press-fitting device that speeds up the press-fitting time and production efficiency; Application No. CN202222859922.0 discloses a core component and core shaft press-fitting mechanism, in which the combined handling component, tensioning component and press-fitting mechanism cooperate to realize the handling and tensioning of the core component, ensure the concentric alignment of the core component, and improve the press-fitting accuracy. However, the current pressing technology for shaft and sleeve products is mainly used in metal-metal and relatively small-sized (Φ<200) products. No relevant research has been found for metal-non-metal and large shaft and sleeve products. The traditional manual pressing method is still used, and the assembly quality cannot be guaranteed.

[0003] At the same time, composite materials are currently widely used in the aerospace military industry. As aerospace structural materials, they have significant effects in weight reduction and high temperature resistance, but some composite materials are relatively brittle. A large number of cabins are composed of metal frames and heat protection layer sets. The product size of the set is above Φ300. It is not easy to clamp the parts using the traditional press-fit method, and the verticality of the press-fit cannot be guaranteed. In addition, for non-metallic materials with high brittleness, the manual press-fit process can easily cause deformation and damage of the non-metallic cabin; secondly, such cabins need to be coated with adhesives to ensure stable assembly. The manual press-fit process cannot accurately control the product's set travel direction. The set process needs to adjust the direction at any time, which can easily cause the press-fit to take a long time and reduce the quality of the adhesive bonding. Summary of the invention

[0048] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation methods. It is understood that the specific implementation methods described herein are only used to explain the relevant content, rather than to limit the present invention. It is also necessary to explain that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings.

[0049] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0050] like Figure 1 As shown, a cabin pressing mechanism provided by the present invention includes a frame 2 and a workpiece mounting seat 303, the frame 2 is a frame structure, and the workpiece mounting seat 303 is located below the frame 2; the workpiece mounting seat 303 is provided with a fixing component, and the fixing component is used to fix the metal cabin on the workpiece mounting seat 303, and a clamping component 21 and a pressing component 22 are also installed on the frame 2, the workpiece mounting seat 303, the clamping component 21 and the pressing component 22 are located on the same vertical line, the workpiece mounting seat 303 is located below the clamping component 21, the clamping component 21 is located below the pressing component 22, and the clamping component 21 is used to clamp the non-metallic cabin to be pressed down, and the pressing component 22 is used to press the clamped non-metallic cabin down onto the metal cabin.

[0051] In order to press the non-metallic cabin body held by the clamping assembly 21 onto the metal cylinder on the workpiece mounting seat 303, the clamping assembly 21 and the pressing assembly 22 can both move up and down on the frame 2, and a lifting assembly is also installed between the clamping assembly 21 and the pressing assembly 22, and the distance between the clamping assembly 21 and the pressing assembly 22 can be adjusted by lifting the lifting assembly. When the non-metallic cabin body needs to be clamped by the clamping assembly 21, the lifting assembly is adjusted to increase the distance between the clamping assembly 21 and the pressing assembly 22; when the non-metallic cabin body is clamped by the clamping assembly 21, the lifting assembly is used to reduce the distance between the clamping assembly 21 and the pressing assembly 22, so that the pressing assembly 22 is pressed against the non-metallic cabin body.

[0052] When the non-metallic cabin needs to be pressed onto the metal cabin, the metal cabin is first fixed to the workpiece mounting seat 303 by means of the fixing assembly, and the spacing between the clamping assembly 21 and the pressing assembly 22 is increased by adjusting the lifting assembly, and the non-metallic cabin is placed into the clamping assembly 21. The clamping assembly 21 clamps the non-metallic cabin, and then, the spacing between the clamping assembly 21 and the pressing assembly 22 is reduced by means of the lifting assembly, so that the pressing assembly 22 is pressed against the non-metallic cabin; finally, the clamping assembly 21 and the pressing assembly 22 move downward synchronously, so that the clamped non-metallic cabin is pressed onto the metal cabin.

[0053] Because the non-metallic cabin body in the present invention needs to be coated with adhesive on the outer wall of the metal cabin body before being press-fitted onto the metal cabin body, after the non-metallic cabin body is press-fitted onto the metal cabin body, the non-metallic cabin body can be bonded and fixed to the metal cabin body by the adhesive. In order to facilitate the coating of the adhesive on the outer wall of the metal cabin body, the workpiece mounting seat 303 in the present invention is set to a rotatable structure, so that after the metal cabin body is fixed on the workpiece mounting seat 303, the rotation of the workpiece mounting seat 303 drives the metal cabin body to rotate, so that the staff can quickly coat the adhesive on the outer wall of the metal cabin body.

[0054] In order to facilitate the fixation of the metal cabin, Figure 5 , Figure 6 , Figure 7As shown, the fixing assembly in the present invention includes an inner flange 3032 and an outer flange 3033, and the inner flange 3032 and the outer flange 3033 are fixed to the workpiece mounting seat 303 by bolts, so that the installation and disassembly of the inner flange 3032 and the outer flange 3033 are more convenient; after the inner flange 3032 and the outer flange 3033 are installed on the workpiece mounting seat 303, the center of the inner flange 3032 and the center of the outer flange 3033 are located at the same point, and there is a certain distance between the outer wall of the inner flange 3032 and the inner wall of the outer flange 3033. Since the lower end of the inner wall of the metal cabin also has a flange, when the metal cabin is installed, the end face of the lower end of the metal cabin and the flange of the lower end of the inner wall of the metal cabin are jointly supported on the end face of the large diameter end of the inner flange 3032, the inner circular surface of the flange at the lower end of the inner wall of the metal cabin is pressed against the outer surface of the small diameter end of the inner flange 3032, and the outer circular surface of the metal cylinder is pressed against the inner surface of the outer flange 3033. Since there is a certain distance between the outer wall of the inner flange 3032 and the inner wall of the outer flange 3033, after the metal cabin is fixed, the distance between the outer circular surface of the large diameter end of the inner flange 3032 and the inner circular surface of the inner flange 3033 constitutes a glue flow groove, so that the excess adhesive coated on the outer wall of the metal cabin is automatically collected in the glue flow groove by its own weight, so that the product quality can be guaranteed.

[0055] like Figure 7 As shown, the workpiece mounting seat 303 also has a threaded seat 3031, and the threaded seat 3031 and the workpiece mounting seat 303 are an integral structure, or the threaded seat 3031 is fixed to the workpiece mounting seat 303 by bolts, and the threaded seat 3031 is located at the center of the workpiece mounting seat 303, and a screw rod 3034 extending vertically upward is threadedly connected to the threaded seat 3031, and the upper end of the screw rod 3034 also has a pressure plate 3035 that can move up and down, and the pressure plate 3035 is in the shape of a cap, and the upper end of the screw rod 3034 also has a pressure block 3036 that can press the pressure plate 3035, and the pressure block 3036 is threadedly matched with the screw rod 3034. Before the non-metallic cabin body is press-fitted, the pressure plate 3035 and the pressure block 3036 are not installed on the screw 3034. When the non-metallic cabin body is press-fitted on the metal cabin body, the pressure plate 3035 is sleeved on the screw 3034, and the pressure plate 3035 cover is set on the metal cabin body. The lower end surface of the pressure plate 3035 is pressed against the upper end surface of the non-metallic cabin body. By tightening the pressure block 3036, the pressure block 3036 presses the pressure plate 3035 on the non-metallic cabin body, so that the relative position of the non-metallic cabin body and the metal cabin body remains stable, and after the adhesive on the metal cabin body solidifies, the product quality is guaranteed.

[0056] Since the screw 3034 is connected to the threaded seat 3031 by threads, the pressure block 3036 and the screw 3034 in the present invention can also be set as an integrated structure. In this case, before the non-metallic cabin body is pressed onto the metal cabin body, the screw 3034 and the pressure plate 3035 are not installed. When the non-metallic cabin body is pressed onto the metal cabin body, the pressure plate 3035 is placed on the metal cabin body, and then the screw 3034 is passed through the pressure plate 3035 and the metal cabin body in turn and inserted into the threaded seat 3031. Finally, the screw 3034 is tightened to press the pressure block 3036 onto the pressure plate 3035.

[0057] like Figure 1 , Figure 2 , Figure 4 As shown, the clamping assembly 21 includes two lower mounting seats 2101, which are symmetrically arranged on the frame 2, and both of the lower mounting seats 2101 can move up and down on the frame 2; at the same time, a lower mounting plate 2102 is installed on the lower mounting seat 2101, and the lower mounting plate 2102 is annular, and the center of the lower mounting plate 2102 is on the same vertical line as the center of the workpiece mounting seat 303; a plurality of swingable pendulums are installed on the lower mounting plate 2102. Arm 2103, multiple swing arms 2103 are evenly spaced along the circumferential direction of the lower mounting plate 2102, and the multiple swing arms 2103 extend along the chord length direction of the lower mounting plate 2102, that is, the swing centers of the multiple swing arms 2103 are located on the same circular ring, the inner ends of the multiple swing arms 2103 are located on the same circular ring, the outer ends of the multiple swing arms 2103 are also located on the same circular ring, and the diameter of the circular ring jointly formed by the inner ends of the multiple swing arms 2103 is smaller than the inner diameter of the lower mounting plate 2102. In order to ensure the swing of the swing arm 2103, a power structure for driving the swing arm 2103 to swing is also installed on the lower mounting plate 2102. The power structure drives the swing arm 2103 to swing toward the center of the lower mounting plate 2102 or the edge of the lower mounting plate 2102, so that the diameter of the circular ring formed by the inner ends of multiple swing arms 2103 becomes larger or smaller. When the swing arm 2103 swings toward the center of the lower mounting plate 2102, the swing arm 2103 holds the non-metallic cabin tightly. When the swing arm 2103 swings toward the edge of the lower mounting plate 2102, the swing arm 2103 releases its hold on the non-metallic cabin.

[0058] Of course, there is no limit to the number of swing arms 2103 on the lower mounting plate 2102, as long as the non-metallic cabin can be held tightly. For example, the number can be two, three, or four.

[0059] In order to prevent the swing arm 2103 from scratching the non-metallic cabin during the process of holding the non-metallic cabin tightly, a roller 2104 can be installed at the inner end of the swing arm 2103, and the roller 2104 can be fully rotated on the swing arm 2103, so that when the swing arm 2103 needs to hold the non-metallic cabin tightly after swinging, the circumferential surface of the roller 2104 is pressed against the outer circumferential surface of the non-metallic cabin. Of course, the roller 2104 can also be made of rubber material or covered with a rubber layer on the surface of the roller 2104, so as to effectively prevent the non-metallic cabin from being scratched when multiple rollers 2104 hold the non-metallic cabin together, so that the quality of the non-metallic cabin can be guaranteed.

[0060] Of course, in the present invention, in order to prevent the non-metallic cabin from having relative displacement with the roller 2104 when the non-metallic cabin is pressed downward by the pressing component 22, a flange can be set at the lower end of the roller 2104 during the design of the roller 2104, so that when multiple rollers 2104 are jointly clamping the non-metallic cabin, the lower end surface of the non-metallic cabin can be jointly supported on the flanges of the multiple rollers 2104, so that when the non-metallic cabin is clamped, the non-metallic cabin is restricted by the flange at the lower end of the roller 2104 and cannot move downward relative to the roller 2104, so that when the pressing component 22 and the clamping component 21 move downward together, there will be no relative displacement between the non-metallic cabin and the clamping component 21, thereby further preventing the non-metallic cabin from being scratched by the roller 2104 during the pressing process.

[0061] In order to ensure that the clamping force of the multiple swing arms 2103 on the non-metallic cabin is equal and the multiple swing arms 2103 can swing synchronously, Figure 4 As shown, the power structure in the present invention is a third linear drive element 2105 installed on the lower mounting plate 2102, and the output end of the third linear drive element 2105 is hinged to the outer end of one of the swing arms 2103, and a linkage structure is connected between two adjacent swing arms 2103. When the third linear drive element 2105 drives the swing arm 2103 connected thereto to swing, the swing arm 2103 will drive the adjacent swing arms 2103 to swing synchronously through the linkage structure, so that one third linear drive element 2105 drives multiple swing arms 2103 to swing synchronously, which not only reduces the use of the third linear drive element 2105, makes the structure of the clamping component 21 simpler, and makes the response of the clamping component 21 faster, so that the clamping of the non-metallic cabin is more stable.

[0062] Of course, without considering the complexity of the clamping assembly 21 and the cost of the equipment, in the present invention, a third linear drive element 2105 can also be connected to a swing arm 2103, and in this case, the clamping of the non-metallic cabin can also be achieved, but the swinging of multiple swing arms 2103 cannot be completely synchronized, and the control method of multiple third linear drive elements 2105 is also more complicated. In the present invention, the third linear drive element 2105 can be selected from a cylinder, a hydraulic cylinder, an electronic telescopic rod, etc. Of course, the selection of the third linear drive element 2105 is not limited to the aforementioned four types. Under the requirement of satisfying the swinging of the swing arm 2103, the third linear drive element 2105 can be selected at will.

[0063] In order to ensure the linkage between multiple swing arms 2103, the linkage structure between two adjacent swing arms 2103 includes a curved guide rail 2107 located on the same side of the multiple swing arms 2103, and the multiple curved guide rails 2107 are fixed to the lower mounting plate 2102 by bolts. The outer end of each swing arm 2103 is also hinged with a connecting rod 2106 extending toward the curved guide rail 2107, and the extended end of the connecting rod 2106 is hinged with a guide shaft that slides with the corresponding curved guide rail 2107, and a pull rod 2108 is also hinged between the extended end of the connecting rod 2106 and the next swing arm 2103. When the third linear drive element 2105 drives one of the swing arms 2103 to swing, it drives the connecting rod 2106 on the swing arm 2103 to move, so that the extended end of the connecting rod 2106 slides along the curved guide rail 2107. The connecting rod 2106 drives the pull rod 2108 to pull the next swing arm 2103 to swing while moving with the swing arm 2103, and repeats in sequence, so that multiple swing arms 2103 swing synchronously. It should be noted here that the curved guide rail 2107 is a guide rail with a curved axis of the slide slot, not a guide rail with a curved appearance.

[0064] Of course, in the present invention, the design of the curved guide rail 2107 can also be omitted. In this case, a curved hole is directly opened at the extended end of the connecting rod 2106, a connecting shaft is hinged at one end of the pull rod 2108 close to the connecting rod 2106, and the connecting shaft is inserted into the curved hole. In this case, the linkage between two adjacent swing arms 2103 can also be satisfied. Of course, there are many linkage structures between two adjacent swing arms 2103, which will not be described one by one here.

[0065] like Figure 1 , Figure 2 , Figure 3As shown, the pressing assembly 22 includes two upper mounting seats 2201, which are symmetrically arranged on the frame 2, and both of the upper mounting seats 2201 can move up and down on the frame 2; the two upper mounting seats 2201 are respectively located above the two lower mounting seats 2101, and an upper mounting plate 2202 is commonly installed on the two upper mounting seats 2201, the upper mounting plate 2202 is located above the lower mounting plate 2102, and the center of the lower mounting plate 2102 and the center of the upper mounting plate 2202 are located on the same vertical line; the upper mounting plate 2202 is in a circular shape, and a small pressing barrel 2206 for pressing down the pressed parts is installed on the lower surface of the upper mounting plate 2202. Because during the press-fitting process of the non-metallic cabin body, the pressing force applied by the press-fitting assembly 22 only acts on the non-metallic cabin body, and the pressing force applied by the press-fitting assembly 22 does not need to act on the metal cabin body, the size of the small press-fitting barrel 2206 is designed so that the inner diameter of the small press-fitting barrel 2206 is larger than the outer diameter of the metal cabin body, the inner diameter of the small press-fitting barrel 2206 is smaller than the outer diameter of the non-metallic cabin body, and the end face of the lower end of the small press-fitting barrel 2206 cooperates with the end face of the upper end of the non-metallic cabin body.

[0066] In order to satisfy the up and down movement of the pressing assembly 22, a first linear drive element 2203 is also installed on the frame 2, and the output end of the first linear drive element 2203 extends in the vertical direction. In order to facilitate the connection between the output end of the first linear drive element 2203 and the upper mounting plate 2202, the output end of the first linear drive element 2203 is also connected to a connecting frame 2204, and the lower end of the connecting frame 2204 is connected to the upper mounting plate 2202. In the present invention, the first linear drive element 2203 can be selected from a cylinder, a hydraulic cylinder, an electronic telescopic rod, a servo electric cylinder, etc. Of course, the selection of the first linear drive element 2203 is not limited to the aforementioned four types. Under the requirement of satisfying the swing of the swing arm 2103, the first linear drive element 2203 can be selected at will.

[0067] like Figure 3 As shown, the pressing assembly 22 also includes a large pressing barrel 2205. When a small-sized non-metallic cabin needs to be pressed, the large pressing barrel 2205 is fixed on the upper surface of the upper mounting plate 2202. When a large-sized non-metallic cabin needs to be pressed, the large pressing barrel 2205 can be removed from the upper mounting plate 2202 and installed on the lower surface of the upper mounting plate 2202, so that the large-sized non-metallic cabin can be pressed. Of course, in the present invention, there is no need to install the large press-packing barrel 2205 on the upper surface of the upper mounting plate 2202, and the large press-packing barrel 2205 can be directly placed on one side of the press-packing mechanism. When needed, the small press-packing barrel 2206 can be removed from the upper mounting plate 2202 and the large press-packing barrel 2205 can be fixed on the upper mounting plate 2202. When not needed, the large press-packing barrel 2205 can be removed from the upper mounting plate 2202 and the small press-packing barrel 2206 can be fixed on the upper mounting plate 2202.

[0068] In the present invention, a pressure sensor can also be installed on the upper mounting plate 2202, so that when the lower pressure component 22 is press-fitting the non-metallic cabin body, the pressure sensor can provide real-time feedback of the working pressure curve to avoid abnormalities in the press-fitting process; at the same time, the sizes of the large press-fitting barrel 2205 and the small press-fitting barrel 2206 in the present invention can be customized according to the size of the non-metallic sleeve to be press-fitted, and the large press-fitting barrel 2205 or the small press-fitting barrel 2206 can cooperate with the metal cabin body during the press-fitting process of the non-metallic cabin body to ensure the verticality of the non-metallic cabin body and prevent deformation during the press-fitting process.

[0069] In order to ensure that the pressing assembly 22 and the clamping assembly 21 always remain in the same vertical line during the up and down movement, a vertical guide rail 24 extending along its height direction is also installed on the frame 2, and a vertical slider 25 that slides with the vertical guide rail 24 is installed on the lower mounting seat 2101 in the clamping assembly 21 and the upper mounting seat 2201 in the pressing assembly 22.

[0070] In order to make the pressing assembly 22 and the clamping assembly 21 more stable during the up and down movement, and because there are two lower mounting seats 2101 in the clamping assembly 21 and two upper mounting seats 2201 in the pressing assembly 22, the vertical guide rails 24 and the vertical slider 25 are designed so that there are at least two vertical guide rails 24, and the multiple vertical guide rails 24 are divided into two groups, and the two groups of vertical guide rails 24 correspond to the two upper mounting seats 2201 respectively, that is, the two groups of vertical guide rails 24 are also symmetrically arranged on the frame 2, and the vertical slider 25 on the upper mounting seat 2201 and the vertical slider 25 on the lower mounting seat 2101 are both slidably matched with the vertical guide rail 24 on the same side. In the present invention, in addition to being two vertical guide rails 24, the vertical guide rails 24 can also be four. In this case, there are two vertical guide rails 24 on both sides of the frame 2, and there are also two vertical sliders 25 on the upper mounting seat 2201 and the lower mounting seat 2101.

[0071] In the present invention, the cooperation mode of the vertical guide rail 24 and the slider can also be replaced by other guide structures, for example, the cooperation mode of the guide rod and the guide sleeve. In this case, the guide rod replaces the vertical guide rail 24, and the guide sleeve replaces the vertical slider 25. The installation mode of the guide rod and the guide sleeve can be the same as the installation mode of the vertical guide rail 24 and the vertical slider 25. Of course, the alternative structure of the cooperation mode of the vertical guide rail 24 and the slider in the present invention is not limited to the cooperation mode of the guide rod and the guide sleeve. Under the condition of ensuring that the pressing component 22 and the clamping component 21 can guide during the up and down movement, the cooperation mode of the vertical guide rail 24 and the slider can also be replaced by other guide structures, which will not be repeated here.

[0072] In the present invention, in order to facilitate the installation of the vertical guide rail 24 on the frame 2, a mounting plate can also be installed on the frame 2, and the vertical guide rail 24 can be installed on the mounting plate; at the same time, in order to prevent the vertical slider 25 on the lower mounting seat 2101 from directly falling off the lower end of the vertical guide rail 24 during the up and down movement of the clamping component 21, a limit block or sensor is also installed at the lower end of the mounting plate to limit the transition downward movement of the lower mounting seat 2101. In the present invention, the rigidity and coaxiality of the pressing process are guaranteed by the sliding cooperation between the vertical guide rail 24 and the vertical slider 25, so that the verticality of the non-metallic cabin can reach 0.1mm during the up and down movement of the pressing component 22 and the clamping component 21.

[0073] In the present invention, in order to ensure the adjustment of the distance between the pressing component 22 and the holding component 21, as shown in FIG. Figure 2 As shown, the lifting component can optionally use a second linear drive element 23 installed on the upper mounting seat 2201, and the output end of the second linear drive element 23 is connected to the lower mounting seat 2101; the second linear drive element 23 can also be directly fixed on the lower mounting seat 2101, and the output end of the second linear drive element 23 is connected to the upper mounting seat 2201; or the two ends of the second linear drive element 23 are directly connected to the upper mounting seat 2201 and the lower mounting seat 2101 respectively.

[0074] In the present invention, the second linear drive element 23 can be selected from a pneumatic cylinder, a hydraulic cylinder, an electronic telescopic rod, a servo electric cylinder, etc. Of course, the selection of the second linear drive element 23 is not limited to the aforementioned four types. The second linear drive element 23 can be selected at will while meeting the swinging requirements of the swing arm 2103.

[0075] like Figure 1 , Figure 5 As shown, the cabin pressing mechanism provided in the present invention also includes a base 1 located below the frame 2, and the two ends of the base 1 horizontally penetrate the frame 2 and extend outward, and the extension direction of the base 1 is perpendicular to the line between the two upper mounting seats 2201; the base 1 is also equipped with a chassis 3 that can reciprocate along its axis, and the workpiece mounting seat 303 is rotatably mounted on the chassis 3. Through the movement of the chassis 3 on the base 1, the chassis 3 can enter or exit the bottom of the frame 2, so that when the metal cabin needs to be installed on the workpiece mounting seat 303, the chassis 3 can be withdrawn from the bottom of the frame 2 for installation, which not only makes the installation of the metal cabin more convenient, but also facilitates the cabin formed after the press-fitting to be withdrawn from the bottom of the frame 2 for subsequent operations, such as the installation of screw rods 3034, pressure plates 3035 and other structures. A handle is provided on one side of the chassis 3, so that the staff can push the chassis 3 through the handle, making the pushing of the chassis 3 more convenient.

[0076] In order to ensure the movement of the chassis 3, a horizontal guide rail 4 is also installed on the base 1, and the horizontal guide rail 4 extends along the axial direction of the base 1; in order to ensure the stability of the chassis 3 during movement, there are at least two horizontal guide rails 4, and the two horizontal guide rails 4 are symmetrically arranged along the central axis of the base 1, and a horizontal slider 5 that slides with the horizontal guide rail 4 is also installed on the lower surface of the chassis 3. There are four horizontal sliders 5, and the four horizontal sliders 5 are respectively located at the four corners of the chassis 3, and the two horizontal sliders 5 located on the same side of the chassis 3 slide with the same horizontal guide rail 4.

[0077] In order to ensure that the workpiece mounting seat 303 on the chassis 3 can accurately correspond to the clamping assembly 21 after the chassis 3 enters the bottom of the frame 2, such as Figure 5 As shown, a thrust block 11 is provided at one end of the base 1 away from the chassis 3 and entering under the chassis 3, so that after the chassis 3 enters under the frame 2 along the base 1, the chassis 3 cannot continue to move forward on the base 1, making the correspondence between the workpiece mounting seat 303 and the clamping assembly 21 faster and more convenient.

[0078] In order to prevent the chassis 3 from being displaced on the base 1 during the process of press-fitting the non-metallic cabin body on the metal cabin body, a locking assembly 301 for locking the base 1 is also installed on the chassis 3, and the locking assembly 301 and the thrust block 11 are located on opposite sides of the chassis 3, so that after the chassis 3 enters under the frame 2, the front and rear of the chassis 3 can be respectively restricted by the locking assembly 301 and the thrust block 11, and the two sides of the chassis 3 can be restricted by the cooperation of the horizontal guide rail 4 and the horizontal slider 5, so that the chassis 3 is firmly fixed under the frame 2, so that the position of the metal cabin of the pressing assembly 22 remains unchanged during the press-fitting of the non-metallic cabin body, thereby avoiding the product being scrapped due to the misalignment of the non-metallic cabin body with the metal cabin body during the press-fitting process.

[0079] like Figure 8 As shown, the locking assembly 301 includes a sleeve 3011 fixed on the chassis 3 and a socket 12 opened on the base 1. The sleeve 3011 and the socket 12 are located on the same straight line, and the sleeve 3011 extends in the vertical direction. A rod 3013 that can move up and down is inserted in the sleeve 3011. When the chassis 3 needs to enter or exit from the bottom of the rack 2, the rod 3013 is pulled out from the sleeve 3011, so that the rod 3013 exits the socket 12; when the chassis 3 enters under the rack 2 and needs to be locked with the base 1, the rod 3013 is inserted from the sleeve 3011 into the socket 12, so that the chassis 3 cannot move along the axial direction of the base 1, and the chassis 3 and the base 1 are locked.

[0080] In order to allow the chassis 3 to enter the bottom of the rack 2 and then the insertion rod 3013 to be automatically inserted into the socket 12, a limiting ring 3012 is provided on the inner wall of the sleeve 3011, the limiting ring 3012 is located at the upper end of the sleeve 3011 or the middle of the sleeve 3011, the insertion rod 3013 passes through the limiting ring 3012, and the lower end of the insertion rod 3013 has a plug 3015; a spring 3016 is sleeved on the insertion rod 3013, the upper end of the spring 3016 is tightly pressed against the lower surface of the limiting ring 3012, and the lower end of the spring 3016 is tightly pressed against the upper end surface of the plug 3015.

[0081] In the present invention, in order to prevent the insertion rod 3013 from directly moving out of the lower end of the sleeve 3011, the insertion rod 3013 is further provided with a large diameter section 3014, the diameter of which is in clearance with the inner diameter of the sleeve 3011. When the insertion rod 3013 is inserted into the sleeve 3011, the large diameter section 3014 is located above the stop ring 3012. When the insertion rod 3013 moves downward along the sleeve 3011, the large diameter section 3014 cooperates with the stop ring 3012, so that the insertion rod 3013 cannot continue to descend after moving downward to a certain distance, thereby preventing the insertion rod 3013 from excessively moving downward.

[0082] In order to prevent the insertion rod 3013 from relatively rotating in the sleeve 3011, a guide hole 3017 may be provided on the sleeve 3011, and a guide pin 30198 inserted in the guide hole 3017 may be provided on the insertion rod 3013, so that the insertion rod 3013 cannot rotate in the sleeve 3011 during the up and down movement of the insertion rod 3013 through the cooperation between the guide hole 3017 and the guide pin 30198. In order to further lock the chassis 3, a pressing rod 3019 that can be pressed against the chassis 3 may be provided at the upper end of the insertion rod 3013, so that the pressing rod 3019 is pressed against the chassis 3 when the insertion rod 3013 is inserted into the jack 12, so that the chassis 3 is better stabilized on the base 1.

[0083] Since the plug 3015 on the plug rod 3013 is inserted into the jack 12 and is pushed by the spring 3016, when the plug 3015 on the plug rod 3013 needs to be withdrawn from the jack 12, the plug rod 3013 needs to be lifted upward manually to compress the spring 3016. However, when the chassis 3 enters or exits the bottom of the rack 2 on the base 1, the staff cannot continue to lift the plug rod 3013. Therefore, in order to prevent the plug 3015 from being pressed against the base 1 by the force of the spring 3016 when the chassis 3 enters or exits the bottom of the rack 2 on the base 1, thereby affecting the movement of the chassis 3, a mounting seat can be installed on the base 1, and the jack 12 is opened on the mounting seat to raise the height of the jack 12, so that when the chassis 3 moves on the base 1, even if the spring 3016 pushes the plug 3015 downward by its own elastic force, the plug 3015 will not directly press against the base 1. In addition, in order to facilitate the insertion of the plug 3015 into the socket 12, the plug 3015 can be configured to be conical, and the socket 12 can be configured to be funnel-shaped to match the plug 3015.

[0084] In order to install the workpiece mounting seat 303, a driving structure 302 is installed in the chassis 3, the output end of the driving structure 302 extends upward through the chassis 3, and a fixed disk 3025 is installed at the output end of the driving structure 302, there is a certain distance between the fixed disk 3025 and the upper surface of the chassis 3, and the workpiece mounting seat 303 is installed on the fixed disk 3025. Since the present invention can be used not only for press-fitting of small-sized non-metallic cabins, but also for press-fitting of large-sized non-metallic cabins, and after the non-metallic cabin and the metal cabin are press-fitted, they need to be removed from the workpiece mounting seat 303 for subsequent processing, therefore, in order to meet the requirements of installing metal cabins of different sizes, and to facilitate the removal of the press-fitted products for subsequent processing, the fixed disk 3025 is plugged and matched with the workpiece mounting seat 303, for example, the fixed disk 3025 has a plug-in column, and the workpiece mounting seat 303 has a plug-in hole that matches the plug-in column.

[0085] The driving structure 302 includes a driving motor 3021 fixedly installed in the chassis 3 and a worm gear 3023 rotatably installed in the chassis 3, and a worm 3022 meshing with the worm gear 3023 is installed at the output end of the driving motor 3021; ​​a support cylinder 3024 is also installed on the worm gear 3023, the support cylinder 3024 and the fixed disk 3025 are an integral structure, and the lower end of the support cylinder 3024 has a disc-shaped end face, which is convenient for the connection between the support cylinder 3024 and the worm gear 3023.

[0086] In the invention, when it is necessary to press-fit a small-sized non-metallic cabin onto a small-sized metal cabin, first lift the insertion rod 3013, pull the chassis 3, and make the chassis 3 withdraw from the bottom of the frame 2; then, install the small-sized workpiece mounting seat 303 on the fixed plate 3025, and install the inner flange 3032 on the workpiece mounting seat 303, support the lower end of the metal cabin on the large-diameter end face of the inner flange 3032, and fix the outer flange 3033 on the workpiece mounting seat 303, and clamp the metal cabin by the inner flange 3032 and the outer flange 3033; then, the driving motor 3021 in the chassis 3 drives the worm 3022 to rotate, the worm 3022 drives the worm wheel 3023 to rotate, and the worm wheel 3023 drives the support cylinder 3024 and the fixed plate 3025 Rotate so that the workpiece mounting base 303, the inner flange 3032, the outer flange 3033, and the metal cabin body rotate synchronously with the fixed plate 3025. At this time, during the rotation of the metal cabin body, the staff will brush the adhesive on the outer wall of the metal cabin body; when the adhesive is brushed, the drive motor 3021 stops rotating, and the staff pushes the chassis 3 under the frame 2, and when the chassis 3 is about to approach the thrust block 11, the plug 3013 is pulled up, and the spring 3016 on the plug 3013 is compressed. When the chassis 3 is pressed against the thrust block 11, the pull on the plug 3013 is released, and the spring 3016 pushes the plug 3015 through its own elastic force, and the plug 3015 drives the plug 3013, so that the plug 3015 is automatically inserted into the jack 12, thereby locking the chassis 3 and the base 1.

[0087] Next, the third linear drive element 2105 contracts, and the third linear drive element 2105 pulls the swing arm 2103 to swing toward the edge of the lower mounting plate 2102. The swing arm 2103 drives the connecting rod 2106 connected thereto to swing while swinging. The connecting rod 2106 drives the pull rod 2108 to pull the next swing arm 2103 to swing while swinging. This is repeated, so that multiple swing arms 2103 swing toward the edge of the lower mounting plate 2102 at the same time, so that the diameter of the ring formed by the rollers 2104 at the inner ends of the multiple swing arms 2103 becomes larger, and the staff puts the non-metallic cabin into the ring formed by the multiple rollers 2104. Inside the circular ring, four-three linear drive elements extend out, and the third linear drive element 2105 pulls the swing arm 2103 to swing toward the center of the lower mounting plate 2102. The swing arm 2103 drives the connecting rod 2106 connected thereto to swing while swinging, and the connecting rod 2106 drives the pull rod 2108 to pull the next swing arm 2103 to swing while swinging, and this is repeated, so that multiple swing arms 2103 are simultaneously swung toward the center of the lower mounting plate 2102, so that the diameter of the circular ring formed by the rollers 2104 at the inner ends of the multiple swing arms 2103 becomes smaller, and the rollers 2104 on the multiple swing arms 2103 jointly hold the non-metallic cabin tightly.

[0088] The second linear drive element 23 contracts, and through the sliding cooperation between the vertical guide rail 24 and the vertical slider 25 on the lower mounting seat 2101, the second linear drive element 23 pulls the lower mounting plate 2102 to move upward, so that the lower mounting plate 2102 gradually approaches the upper mounting plate 2202. When the upper end surface of the non-metallic cabin body and the lower end surface of the small press barrel 2206 are close to each other, the second linear drive element 23 stops contracting; then, the first linear drive element 2203 extends, and through the sliding cooperation between the vertical guide rail 24 and the vertical slider 25 on the upper mounting seat 2201, and the vertical The guide rail 24 slides in cooperation with the vertical slider 25 on the lower mounting seat 2101, and the first linear drive element 2203 pushes the large pressure-loading barrel 2205, the upper mounting plate 2202, and the small pressure-loading barrel 2206 to move downward synchronously. During the downward movement of the large pressure-loading barrel 2205, the upper mounting plate 2202, and the small pressure-loading barrel 2206, the non-metallic cabin is pushed by the downward pressure loading barrel, and the non-metallic cabin, the lower mounting plate 2102, the swing arm 2103 and other structures move downward synchronously with the small pressure-loading barrel 2206, so that the non-metallic cabin is gradually pressed onto the metal cabin.

[0089] When the non-metal cabin body is completely pressed onto the metal cabin body, the third linear drive element 2105 contracts, and the third linear drive element 2105 pulls the swing arm 2103 to swing toward the edge of the downward mounting plate 2102. The swing arm 2103 drives the connecting rod 2106 connected thereto to swing while swinging, and the connecting rod 2106 drives the pull rod 2108 to pull the next swing arm 2103 to swing while swinging, and this is repeated, so that multiple swing arms 2103 swing toward the edge of the downward mounting plate 2102 at the same time, so that the rollers 2104 at the inner ends of the multiple swing arms 2103 are formed As the diameter of the circular ring increases, the rollers 2104 at the inner ends of the multiple swing arms 2103 lose their grip on the non-metallic cabin; at the same time, the first linear drive element 2203 contracts, and the first drive pulls the large pressure-loading barrel 2205, the upper mounting plate 2202, and the small pressure-loading barrel 2206 to move upward synchronously. During the upward movement of the large pressure-loading barrel 2205, the upper mounting plate 2202, and the small pressure-loading barrel 2206, the lower mounting plate 2102, the swing arm 2103 and other structures are driven by the second linear drive element 23 to move upward synchronously with the small pressure-loading barrel 2206.

[0090] Finally, the staff lifts the insertion rod 3013 and pulls the chassis 3 to withdraw the chassis 3 from under the frame 2; the pressure plate 3035 is mounted on the screw 3034 with the pressure block 3036, and the lower end of the screw 3034 is screwed into the threaded seat 3031. As the screw 3034 is tightened, the pressure block 3036 on the screw 3034 presses the pressure plate 3035, and the lower end face of the pressure plate 3035 is pressed against the upper end face of the non-metallic cabin body, thereby continuing to press the non-metallic cabin body, and clamping the non-metallic cabin body with a clamp to facilitate subsequent curing; the workpiece mounting seat 303 is removed from the fixed plate 3025, and a new workpiece mounting seat 303 is installed on the fixed plate 3025 to continue to realize the press-fitting between the non-metallic cabin body and the metal cabin body.

[0091] When the present invention needs to press-fit a large-sized non-metallic cabin onto a large-sized metal cabin, the operation method is different from that of pressing a small-sized non-metallic cabin onto a small-sized metal cabin in that: the large-sized workpiece mounting seat 303 with the inner flange 3032 and the outer flange 3033 is replaced, the small press-fitting barrel 2206 and the upper mounting plate 2202 are removed, and the large press-fitting barrel 2205 is installed on the upper mounting plate 2202. The specific steps of press-fitting are the same as those of the large-sized non-metallic cabin.

[0092] (1) In the present invention, the first linear drive element 2203—vertical slide rail 24, vertical slider 25—pressing assembly 22 can ensure the travel path direction of the press-fitting process and accurately control the press-fitting step to 0.1 mm, thereby ensuring the verticality and coaxiality of the press-fitting;

[0093] (2) The present invention can ensure the correct clamping of the non-metallic cabin by providing the large press-fitting barrel 2205 and the small press-fitting barrel 2204, thereby avoiding deformation of the non-metallic cabin during the clamping and press-fitting processes. The replaceable structure can be adapted to assemble cabins of various models;

[0094] (3) By providing a clamping assembly 21 and providing a limit block or sensor on the frame 2 to limit the transition downward movement of the lower mounting seat 2101, the electrical and mechanical dual limit protection functions can be used to avoid the non-metallic sleeve from being deformed during the pressing process and the occurrence of over-top position failures during the return process of the clamping assembly 21 and the pressing assembly 22;

[0095] (4) Through the cooperation of the horizontal guide rail 4 and the horizontal slider 5, the chassis 3 can easily enter or exit from the bottom of the rack 2, which is convenient for the installation of the metal cabin and can achieve the curing molding process after the cabin is assembled; by making the workpiece mounting seat 303 rotatable, the non-metal cabin and the metal cabin can be better tightly assembled to avoid the possibility of deformation and damage of the non-metal cabin;

[0096] (5) The present invention can minimize the uncertainty caused by manual processes by means of automated and stable clamping and pressing, and can greatly improve the assembly efficiency of the cabin.

[0097] In addition to being used for cabin press-fitting, the present invention can also be used for press-fitting between other tubes and barrels. When used for press-fitting between other tubes and barrels, the materials of the tubes and barrels are not limited.
