Description

Technical Field

[0001] This utility model relates to the field of press-fitting machines, specifically to a press-fitting machine for a steering cover assembly. Background Technology

[0002] The assembly process for the steering cover assembly (inner ring of the spherical plain bearing and steering cover) of dryland drive axle products involves manual, one-piece loading (spherical plain bearing and steering cover) and manual pressing using a single-column hydraulic press. This process presents several safety hazards: manual operation increases the risk of injury from pinching; it is inefficient due to the long loading and unloading time, affecting the overall cycle time; and it is physically demanding due to the fatigue caused by frequent movement of personnel.

[0003] To address the above issues and eliminate the drawbacks of the current operating methods, there is an urgent need in this field to design a semi-automated operating device that can safely, efficiently, and easily complete the operation. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to achieve the press-fitting of the steering cover assembly.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A steering cap assembly pressing machine includes a main frame, a steering cap material storage and feeding assembly, a steering cap feeding guide rail, a spherical bearing material storage and feeding assembly, and a pressing assembly. The steering cap material storage and feeding assembly, the steering cap feeding guide rail, and the pressing assembly are arranged sequentially. The discharge end of the spherical bearing material storage and feeding assembly is located below the pressing assembly. The steering cap feeding guide rail, the spherical bearing material storage and feeding assembly, and the pressing assembly are all mounted on the main frame.

[0006] The beneficial effects of this utility model are as follows: the steering cap is stored in the steering cap storage and feeding assembly, and then conveyed to the steering cap feeding guide rail, finally reaching the pressing assembly; the spherical bearing is stored in the spherical bearing storage and feeding assembly, and then conveyed to the bottom of the pressing assembly. The pressing assembly applies pressure to the steering cap and the spherical bearing, causing the steering cap to press downward into the spherical bearing, completing the pressing of both. The steering cap assembly pressing machine uses semi-automatic equipment to replace manual operation, optimizing single-piece manual operation into semi-automatic / automatic centralized operation for the pressing of steering cap assemblies for dryland drive axle products. This achieves the effects of avoiding safety risks in the pressing process, improving work efficiency, improving production line balance, and reducing labor intensity.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the swivel cap storage and feeding assembly includes a feeding frame, a turntable motor, a swivel cap storage turntable, a swivel cap tray, a lifting motor, a lifting fork, and a feeding mechanism. The swivel cap storage turntable is rotatably mounted on the feeding frame. The turntable motor is drivenly connected to the swivel cap storage turntable. The swivel cap tray is slidably connected to the swivel cap storage turntable in the vertical direction. The lifting motor is fixedly installed. The lifting fork is fixedly connected to the drive end of the lifting motor. The lifting fork extends below the swivel cap tray and drives the swivel cap tray to rise or fall. The feeding mechanism is located above the swivel cap storage turntable. The feeding mechanism is fixedly connected to the main frame and pushes the swivel caps on the swivel cap tray laterally into the swivel cap feeding guide rail.

[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: multiple swivel caps are stacked on the swivel cap tray for storage. The turntable motor drives the swivel cap storage turntable to rotate, thereby rotating the stack of swivel caps that need to be loaded to the bottom of the loading mechanism. Then, the lifting motor drives the lifting fork to move upward, lifting the swivel cap tray upward until the topmost swivel cap is at the same height as the swivel cap loading guide rail. Then, the loading mechanism pushes the topmost swivel cap laterally into the swivel cap loading guide rail.

[0010] Furthermore, the turning cover storage turntable is provided with multiple sets of lifting and avoidance notches along its circumference to avoid the lifting fork. There is a lower gap between the bottom surface of the turning cover storage turntable and the feeding frame. Multiple turning cover trays are provided, and the multiple turning cover trays are arranged one-to-one above the multiple sets of lifting and avoidance notches. At least two tray guide posts are fixed on the turning cover storage turntable around each set of lifting and avoidance notches. The turning cover tray is slidably connected to the corresponding tray guide post.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the pallet guide post provides vertical guidance for the swivel cap pallet, and the lifting fork can avoid the gap during its up-and-down movement. Thus, after one of the swivel cap pallets has been loaded, the lifting fork moves the swivel cap pallet downwards, and the swivel cap pallet falls back onto the swivel cap storage turntable. The lifting fork continues to move downwards to the lower interval space, and the swivel cap storage turntable rotates, causing a new stack of swivel caps to rotate to the loading mechanism. The lifting fork, located within the lower interval space, can avoid the rotating swivel cap storage turntable and the pallet guide post.

[0012] Furthermore, the feeding mechanism includes a steering cap feeding cylinder, a receiving plate, a receiving cylinder, and a feeding support plate. The steering cap feeding cylinder is fixedly connected to one end of the feeding support plate, and the other end of the feeding support plate is fixedly connected to the main frame. The receiving cylinder is fixedly connected to the main frame, and the piston rod of the receiving cylinder is fixedly connected to the receiving plate. The piston rod of the receiving cylinder faces the receiving plate, and one end of the receiving plate is at the same height as the steering cap feeding guide rail and slides in cooperation with it.

[0013] The beneficial effects of adopting the above-mentioned further solution are as follows: after the steering cover tray raises the uppermost steering cover to the same height as the steering cover feeding guide rail, the receiving cylinder extends, so that the two sides of the receiving tray are inserted into the lower sides of the steering cover. Then the receiving cylinder retracts, the steering cover feeding cylinder extends, and pushes the steering cover into the steering cover feeding guide rail.

[0014] Furthermore, the steering cover feeding guide rail includes a first guide rail body and a first bracket. There are two first guide rail bodies, which are parallel to each other and spaced apart. The two first guide rail bodies have a steering cover sliding groove on their opposite sides. The lower end of the first bracket is fixedly connected to the main frame, and the upper end of the first bracket is fixedly connected to the first guide rail body.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the first guide rail body is supported by the first bracket, and the two sides of the steering cover can slide along the two steering cover grooves. In this way, the steering cover can be suspended and slid above the main frame for subsequent pressing with the spherical bearing.

[0016] Furthermore, the spherical bearing material storage and feeding assembly includes a material storage cylinder, a spherical bearing feeding cylinder, and a spherical bearing guide groove. The spherical bearing guide groove, the material storage cylinder, and the spherical bearing feeding cylinder are sequentially fixed on the main frame. The material storage cylinder has through holes on opposite sides at its lower end. The piston rod of the spherical bearing feeding cylinder extends into or retracts into the material storage cylinder through one of the through holes. The other through hole communicates with one end of the spherical bearing guide groove, and the other end of the spherical bearing guide groove is located below the pressing assembly.

[0017] The beneficial effect of adopting the above-mentioned further solution is that: the spherical bearing is stored in the storage cylinder. When the spherical bearing feeding cylinder extends, the lowest spherical bearing is pushed into the spherical bearing guide groove through the through hole at the lower end of the storage cylinder, and the spherical bearing closest to the pressing assembly in the spherical bearing guide groove is pushed out to the bottom of the pressing assembly.

[0018] Furthermore, the spherical bearing storage and feeding assembly also includes a spherical bearing limiting block, which is fixedly connected to the main frame and is respectively disposed on both sides below the pressing assembly at the other end of the spherical bearing guide groove.

[0019] The beneficial effect of adopting the above-mentioned further solution is that after the spherical plain bearing is pushed out of the spherical plain bearing guide groove, it is positioned by the spherical plain bearing limiting block, which facilitates subsequent press-fitting.

[0020] Furthermore, the pressing assembly includes a press, a pressing plate, a spring, and a spring guide post. The lower end of the spring guide post is fixedly connected to the main frame, and the upper end of the spring guide post is fixed with a limit nut. The pressing plate is slidably connected to the spring guide post. The spring is sleeved on the outside of the spring guide post, and both ends of the spring abut against the bottom surface of the main frame and the pressing plate, respectively. The pressing plate has opposing plate grooves on both sides, and the top surface of the pressing plate has a pressure head clearance hole. The pressure head of the press is located in the pressure head clearance hole.

[0021] The beneficial effects of adopting the above-mentioned further solution are as follows: the steering cover slides along the steering cover feeding guide rail into the tray groove of the pressing tray, and the press head of the press presses the steering cover downward. The steering cover, along with the pressing tray, moves downward under the guidance of the spring guide column, the spring is compressed, and the lower end of the steering cover is pressed into the spherical bearing. Subsequently, the press head of the press lifts up, and the pressing tray returns to its original position under the action of the spring.

[0022] Furthermore, the steering cap assembly press-fitting machine also includes a discharge guide rail, which is fixedly connected to the main frame, and one end of the discharge guide rail is connected to the press-fitting assembly.

[0023] The beneficial effect of adopting the above-mentioned further solution is that as the steering cover material feeding assembly feeds a new steering cover into the steering cover feeding guide rail, the steering cover in the steering cover feeding guide rail pushes the steering cover assembly in the pressing assembly to the discharge guide rail, and pushes the steering cover at the discharge end of the steering cover feeding guide rail into the pressing assembly.

[0024] Furthermore, the discharge guide rail includes a horizontal discharge section and an inclined discharge section. One end of the horizontal discharge section is connected to the pressing assembly, and the other end is fixedly connected to one end of the inclined discharge section. The other end of the inclined discharge section extends obliquely downward.

[0025] The beneficial effect of adopting the above-mentioned further solution is that the steering cap assembly is conveyed backward along the horizontal and inclined discharge sections. A collection box can be placed below the end of the inclined discharge section, and the steering cap assembly falls directly into the collection box along the inclined discharge section; or it can enter the subsequent production line.

[0042] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0043] like Figures 1-9 As shown, this embodiment provides a steering cap assembly pressing machine, including a main frame, a steering cap material feeding assembly 100, a steering cap feeding guide rail 200, a spherical bearing material feeding assembly 300, and a pressing assembly 400. The steering cap material feeding assembly 100, the steering cap feeding guide rail 200, and the pressing assembly 400 are arranged sequentially. The discharge end of the spherical bearing material feeding assembly 300 is located below the pressing assembly 400. The steering cap feeding guide rail 200, the spherical bearing material feeding assembly 300, and the pressing assembly 400 are all mounted on the main frame.

[0044] Steering cap 1 is stored in steering cap storage and feeding assembly 100 and conveyed to steering cap feeding guide rail 200, finally reaching pressing assembly 400; spherical bearing 2 is stored in spherical bearing storage and feeding assembly 300 and conveyed to the bottom of pressing assembly 400. Pressing assembly 400 applies pressure to steering cap 1 and spherical bearing 2, pressing steering cap 1 downward into spherical bearing 2, completing the pressing of both. The steering cap assembly pressing machine uses semi-automatic equipment to replace manual operation, optimizing single-piece manual operation into semi-automatic / automatic centralized operation for pressing steering cap assemblies of dryland drive axle products. It can achieve the effects of avoiding safety risks in the pressing process, improving operation efficiency, improving production line balance, and reducing labor intensity.

[0045] Based on the above technical solutions, such as Figure 3As shown, the swivel cap storage and feeding assembly 100 includes a feeding frame, a turntable motor, a swivel cap storage turntable 101, a swivel cap tray 102, a lifting motor 104, a lifting fork 105, and a feeding mechanism. The swivel cap storage turntable 101 is rotatably mounted on the feeding frame. The turntable motor is drivenly connected to the swivel cap storage turntable 101. The swivel cap tray 102 is slidably connected to the swivel cap storage turntable 101 in the vertical direction. The lifting motor 104 is fixedly installed. The lifting fork 105 is fixedly connected to the drive end of the lifting motor 104. The lifting fork 105 extends below the swivel cap tray 102 and drives the swivel cap tray 102 to rise or fall. The feeding mechanism is located above the swivel cap storage turntable 101. The feeding mechanism is fixedly connected to the main frame and pushes the swivel cap 1 on the swivel cap tray 102 laterally into the swivel cap feeding guide rail 200.

[0046] Multiple swivel caps are stacked on the swivel cap tray 102 for storage. The turntable motor drives the swivel cap storage turntable 101 to rotate, thereby rotating the stack of swivel caps that need to be loaded to the bottom of the loading mechanism. Then, the lifting motor 104 drives the lifting fork 105 to move upward, lifting the swivel cap tray 102 upward until the topmost swivel cap 1 is at the same height as the swivel cap loading guide rail 200. Then, the loading mechanism pushes the topmost swivel cap 1 laterally into the swivel cap loading guide rail 200.

[0047] Optionally, the feeding frame can be fixed or installed on a movable trolley for easy material transfer.

[0048] Specifically, the lifting motor 104 is a linear motor, and its driving end is a slider of the linear motor. The lifting motor 104 can also be replaced by a common linear drive mechanism such as a pneumatic cylinder or a hydraulic cylinder.

[0049] Based on any of the above schemes, the directional pressure cap storage turntable 101 is provided with multiple sets of lifting avoidance notches along its circumference to avoid the lifting fork 105. There is a lower gap space between the bottom surface of the directional pressure cap storage turntable 101 and the feeding frame. Multiple directional pressure cap trays 102 are provided, and the multiple directional pressure cap trays 102 are arranged one-to-one above the multiple sets of lifting avoidance notches. At least two tray guide posts 103 are fixed on the directional pressure cap storage turntable 101 around each set of lifting avoidance notches. The directional pressure cap tray 102 is slidably connected to the corresponding tray guide post 103.

[0050] The pallet guide post 103 provides vertical guidance for the swivel cap pallet 102, allowing the lifting fork 105 to avoid gaps during its vertical movement. Thus, after one of the swivel cap 1s on the swivel cap pallet 102 has finished loading, the lifting fork 105 moves the swivel cap pallet 102 downwards, causing it to fall back onto the swivel cap storage turntable 101. The lifting fork 105 continues to move downwards to the lower interval space, where the swivel cap storage turntable 101 rotates, causing a new stack of swivel caps 1 to rotate to the loading mechanism. The lifting fork 105, located within the lower interval space, can avoid the rotating swivel cap storage turntable 101 and the pallet guide post 103.

[0051] Specifically, each set of lifting clearance gaps includes at least two spaced lifting clearance gaps, the number of lifting clearance gaps in each set is the same as the number of fork teeth of the lifting fork 105, and the shape of the lifting clearance gaps is similar to the shape of the fork teeth.

[0052] Specifically, the steering cover tray 102 is slidably connected to the corresponding tray guide post 103. More specifically, one steering cover tray 102 is slidably connected to at least two tray guide posts 103 around the corresponding lifting clearance notch. More specifically, the tray guide post 103 is cylindrical, such as... Figure 4 As shown, the steering cover tray 102 has a strip-shaped hole that slides with it.

[0053] Based on any of the above solutions, the feeding mechanism includes a steering cap feeding cylinder 106, a receiving plate 107, a receiving cylinder 108, and a feeding support plate 109. The steering cap feeding cylinder 106 is fixedly connected to one end of the feeding support plate 109, and the other end of the feeding support plate 109 is fixedly connected to the main frame. The receiving cylinder 108 is fixedly connected to the main frame, and the piston rod of the receiving cylinder 108 is fixedly connected to the receiving plate 107. The piston rod of the receiving cylinder 108 faces the receiving plate 107, and one end of the receiving plate 107 is at the same height as the steering cap feeding guide rail 200 and slides in cooperation with it.

[0054] After the steering cover tray 102 raises the uppermost steering cover 1 to the same height as the steering cover loading guide rail 200, the receiving cylinder 108 extends, so that the receiving plate 107 is inserted into the lower sides of the steering cover 1. Then the receiving cylinder 108 retracts, and the steering cover loading cylinder 106 extends, pushing the steering cover 1 into the steering cover loading guide rail 200.

[0055] Specifically, such as Figure 5 As shown, the longitudinal section of the receiving tray 107 is a C-shape with the opening facing downwards, and the bottom plate of the receiving tray 107 is flush with the bottom surface of the steering cover loading guide rail 200. The upper end of the steering cover 1 is slidably fitted with this C-shaped structure.

[0056] Alternatively, the steering gland feeding cylinder 106 and the receiving cylinder 108 can be replaced with a linear motor, hydraulic cylinder or other linear drive mechanism.

[0057] Based on any of the above schemes, such as Figure 8 As shown, the steering cover feeding guide rail 200 includes a first guide rail body 201 and a first bracket 202. There are two first guide rail bodies 201, which are parallel to each other and spaced apart. The two first guide rail bodies 201 have a steering cover sliding groove on their opposite sides. The lower end of the first bracket 202 is fixedly connected to the main frame, and the upper end of the first bracket 202 is fixedly connected to the first guide rail body 201.

[0058] The first guide rail body 201 is supported by the first bracket 202, and the two sides of the steering cover 1 can slide along the two steering cover grooves. In this way, the steering cover 1 can be suspended and slid above the main frame for subsequent pressing with the spherical bearing 2.

[0059] Optionally, the upper ends of the two first guide rail bodies 201 can be connected by a connecting rod to increase the strength of the overall structure.

[0060] Specifically, the longitudinal section of the first guide rail body 201 is C-shaped.

[0061] Based on any of the above schemes, such as Figure 6 As shown, the spherical bearing material storage and feeding assembly 300 includes a material storage cylinder 301, a spherical bearing feeding cylinder 302, and a spherical bearing guide groove 303. The spherical bearing guide groove 303, the material storage cylinder 301, and the spherical bearing feeding cylinder 302 are sequentially fixed on the main frame. The material storage cylinder 301 has through holes on opposite sides at its lower end. The piston rod of the spherical bearing feeding cylinder 302 extends into or retracts into the material storage cylinder 301 through one of the through holes. The other through hole communicates with one end of the spherical bearing guide groove 303. The other end of the spherical bearing guide groove 303 is located below the pressing assembly 400.

[0062] The spherical bearing 2 is stored in the storage cylinder 301. When the spherical bearing feeding cylinder 302 extends, the lowest spherical bearing 2 is pushed into the spherical bearing guide groove 303 through the through hole at the lower end of the storage cylinder 301, and the spherical bearing 2 closest to the pressing assembly 400 in the spherical bearing guide groove 303 is pushed out to the direct under the pressing assembly 400.

[0063] In one specific example, the height of the through hole on the side of the storage cylinder 301 facing the spherical bearing feeding cylinder 302 is less than the height of the spherical bearing 2. An L-shaped push plate is fixed to the end of the piston rod of the spherical bearing feeding cylinder 302. The L-shaped push plate extends into the through hole and pushes the spherical bearing 2. This prevents the spherical bearing 2 from falling out from the side facing the spherical bearing feeding cylinder 302.

[0064] Based on any of the above solutions, the spherical bearing storage and feeding assembly 300 further includes a spherical bearing limiting block 304, which is fixedly connected to the main frame and is respectively disposed on both sides below the press-fit assembly 400 at the other end of the spherical bearing guide groove 303.

[0065] After the spherical plain bearing 2 is pushed out of the spherical plain bearing guide groove 303, it is positioned by the spherical plain bearing limiting block 304, which facilitates subsequent press-fitting.

[0066] Based on any of the above solutions, the pressing assembly 400 includes a press 401, a pressing plate 402, a spring 403, and a spring guide post 404. The lower end of the spring guide post 404 is fixedly connected to the main frame, and the upper end of the spring guide post 404 is fixed with a limit nut. The pressing plate 402 is slidably connected to the spring guide post 404. The spring 403 is sleeved on the outside of the spring guide post 404, and both ends of the spring 403 abut against the main frame and the bottom surface of the pressing plate 402, respectively. The pressing plate 402 has opposing plate grooves on both sides, and the top surface of the pressing plate 402 has a pressure head clearance hole. The pressure head of the press 401 is located in the pressure head clearance hole.

[0067] The steering cover 1 slides along the steering cover loading guide 200 into the tray groove of the pressing tray 402, and the press head of the press 401 presses the steering cover 1 downward. The steering cover 1, along with the pressing tray 402, moves downward under the guidance of the spring guide post 404, compressing the spring 403, and pressing the lower end of the steering cover 1 into the spherical bearing 2. Subsequently, the press head of the press 401 lifts, and the pressing tray 402 returns to its original position under the action of the spring 403.

[0068] Specifically, multiple sets of springs 403 and spring guide posts 404 are provided at intervals along the circumference of the press-fitting plate 402.

[0069] The main frame is the frame of the press 401, or a separately installed frame.

[0070] Based on any of the above schemes, the steering cap assembly press machine also includes a discharge guide rail 500, which is fixedly connected to the main frame and one end of which is connected to the press assembly 400.

[0071] As the steering cover material feeding assembly 100 feeds a new steering cover 1 into the steering cover feeding guide rail 200, the steering cover 1 in the steering cover feeding guide rail 200 pushes the steering cover assembly in the pressing assembly 400 to the discharge guide rail 500, and pushes the steering cover 1 at the discharge end of the steering cover feeding guide rail 200 into the pressing assembly 400.

[0072] Based on any of the above schemes, the discharge guide rail 500 includes a horizontal discharge section and a tilted discharge section. One end of the horizontal discharge section is connected to the pressing assembly 400, and the other end is fixedly connected to one end of the tilted discharge section. The other end of the tilted discharge section extends obliquely downward.

[0073] The steering cap assembly is conveyed backward along the horizontal and inclined discharge sections. A collection box can be placed below the end of the inclined discharge section, and the steering cap assembly falls directly into the collection box along the inclined discharge section; or it can enter the subsequent production line.

[0074] Specifically, the structure of the discharge guide rail 500 is the same as that of the steering pressure cover feeding guide rail 200. The discharge guide rail 500 includes a second guide rail body and a second support. There are two second guide rail bodies, which are parallel to each other and spaced apart. The two second guide rail bodies have a steering pressure cover groove on their opposite sides. The lower end of the second support is fixedly connected to the main frame, and the upper end of the second support is fixedly connected to the second guide rail body.
