Description

A pressing station Technical Field

[0001] This utility model relates to the field of hydraulic pump processing technology, and in particular to a press-fitting station. Background Technology

[0002] Because different parts of an excavator require different hydraulic circuit controls for their movements, the power components in the excavator's hydraulic system often adopt a dual-pump series structure, that is, two single-piston pumps connected in series through an intermediate structure.

[0003] For example, application number CN202211627486.2 discloses a compact dual variable displacement piston pump, including a front pump and a rear pump, which are fixedly connected as a single unit with their bottoms facing each other via an intermediate body. This bottom-facing installation allows the intermediate body to serve as the rear cover for both pumps, eliminating the need for separate rear covers. The intermediate body has a central through-hole machined along its axis, facilitating the connection of the drive shafts of the two pumps for series drive. To rotatably support the drive shafts of the two pumps, symmetrical bearing locating cavities are machined at both ends of the central through-hole of the intermediate body, each housing a rolling bearing for rotatably supporting the drive shaft.

[0004] In other words, bearings need to be assembled in the intermediate body to rotate and support the drive shaft of the two pumps. In the existing technology, the bearings in the intermediate body still need to be assembled manually, which is inefficient and has poor precision. Summary of the Invention

[0005] To address the technical problems of low assembly efficiency and poor precision of bearings in intermediate bodies in existing technologies, this utility model provides a press-fitting station that solves the aforementioned technical problems.

[0006] To solve the above-mentioned technical problems, this utility model provides a pressing station, comprising:

[0007] The pressure head is horizontally slidably assembled and is driven to move by a first driving member;

[0008] A support plate is horizontally slidably assembled, and the support plate is driven to move by a second driving member. The support plate is opposite to and spaced apart from the pressure head.

[0009] The support platform is used to support the workpiece. The support platform transports the workpiece to the pressing position between the pressure head and the support plate. During pressing, the pressure head pushes the workpiece to slide and press it against the support plate.

[0010] According to one embodiment of the present invention, the support platform rotatably supports the workpiece, and both ends of the workpiece are press-fitted along the axial direction.

[0011] According to one embodiment of the present invention, the support platform includes a base plate, a rotating plate, a sliding assembly, and a placement fixture. The rotating plate is rotatably supported by the base plate, and the placement fixture is mounted on the rotating plate via the sliding assembly. The workpiece is placed on the placement fixture.

[0012] According to one embodiment of the present invention, a limiting component is provided between the base plate and the rotating plate. The limiting component includes a limiting member mounted on the base plate and a limiting groove located on the outer peripheral surface of the rotating plate. The limiting member elastically abuts against the outer peripheral surface of the rotating plate. When the limiting groove moves to the position of the limiting member, the limiting member can extend into the limiting groove to form a limit.

[0013] According to one embodiment of the present invention, there are two limiting grooves, which are evenly distributed. The limiting component is a bearing, and both ends of the limiting groove are inclined surfaces.

[0014] According to one embodiment of the present invention, the sliding assembly includes a fixed plate and a sliding plate. The fixed plate is fixed to the rotating plate, and two stops are formed at intervals on the fixed plate. The two ends of the sliding plate are respectively slidably engaged with the two stops. The stops extend to the upper surface of the sliding plate to prevent the sliding plate from detaching from the fixed plate.

[0015] According to one embodiment of the present invention, the stop is further provided with a locking member, and the sliding plate is provided with a locking groove. The locking member extends into the locking groove to lock the sliding plate.

[0016] According to one embodiment of the present invention, a reset assembly is further provided on the fixed plate. The reset assembly is symmetrically distributed at both ends of the sliding direction of the sliding plate. The reset assembly includes a guide rod and an elastic element. The guide rod extends into the sliding plate, and the sliding plate can slide along the guide rod. The elastic element is sleeved on the guide rod and acts on the sliding plate.

[0017] According to one embodiment of the present invention, the support platform is slidably mounted on a slide rail, and the support platform moves along the slide rail from the loading position to the pressing position. The loading position and the pressing position are respectively provided with a limiting structure for limiting the support platform and a locking structure for locking the support platform.

[0018] According to one embodiment of the present invention, the extension direction of the slide rail is perpendicular to the sliding direction of the pressure head pushing the workpiece.

[0019] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0020] 1. The pressing station of this utility model supports the workpiece by setting up a bearing platform, and transports the workpiece between the pressing head and the support plate. The pressing head can be fitted with a bearing, which is automatically pressed into the workpiece to achieve pressing without manual pressing, thus improving pressing efficiency. During pressing, the pressing head can push the workpiece to slide and press it tightly on the support plate to ensure the pressing force and thus ensure pressing accuracy.

[0021] 2. The pressing station of this utility model is specifically equipped with a support platform structure. When the workpiece is supported by the support platform, the rotary plate can rotate to adjust the position of the workpiece so that the two ends of the workpiece are facing the pressing head. The pressing head can press the two ends of the workpiece with bearings. The setting of the limiting component can limit the position of the rotary plate, thereby limiting the position of the workpiece. The workpiece can also slide on the support platform through the sliding component. During pressing, the workpiece can slide on the support platform until it is pressed tightly onto the support plate to ensure the pressing force.

[0022] 3. The pressing station of this utility model is equipped with a limiting component including a limiting element and a limiting groove. The limiting element is a bearing, and the two ends of the limiting groove are inclined surfaces. When the rotary plate rotates to the point where the limiting groove aligns with the limiting element, the limiting element can enter the limiting groove to achieve limiting. When it is necessary to release the limiting, only a large rotational force is required to make the limiting element leave the limiting groove. That is, the limiting component can automatically limit the rotary plate and facilitate the release of the limiting.

[0023] 4. In the pressing station of this utility model, two stops are provided on the fixed plate of the sliding assembly to limit the sliding direction of the sliding plate. The stops can also hook the sliding plate to prevent it from detaching from the fixed plate from above. The locking parts on the stops and the locking grooves on the sliding plate can lock the position of the sliding plate. A reset assembly is provided on the fixed plate. The guide rod of the reset assembly can guide the sliding plate, and the elastic element can provide elastic reset force to the sliding plate. When the pressing head retracts, the sliding plate can be reset under the action of the reset assembly.

[0024] 5. In this utility model's pressing station, the support platform can move along the slide rail from the loading position to the pressing position. When the support platform is in the loading position, it is convenient to place the workpiece on the support platform; when the support platform is in the pressing position, the pressing head extends to press the workpiece. Limiting structures and locking structures are respectively provided at the loading position and the pressing position to limit and lock the support platform, thereby achieving positioning of the support platform.

[0041] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0042] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0043] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0046] As shown in Figures 1-2, this embodiment provides a pressing station, including a pressing head 1, a support plate 2, and a bearing platform 3. The pressing head 1 and the support plate 2 are arranged opposite to each other and spaced apart, forming a pressing position between the pressing head 1 and the support plate 2. The bearing platform 3 carries and transports the workpiece 20 to the pressing position. A bearing 30 is sleeved on the pressing head 1. The pressing head 1 moves toward the workpiece 20 to press the bearing 30 into the workpiece 20. During pressing, the workpiece 20 slides appropriately on the bearing platform 3 and is pressed tightly onto the support plate 2 to ensure the pressing effect.

[0047] As a preferred technical solution in this embodiment, the pressure head 1, the support plate 2, and the bearing platform 3 are all assembled on the worktable 5.

[0048] As shown in Figures 3-4, the pressure head 1 is horizontally slidably assembled. Specifically, the pressure head 1 is horizontally slidably assembled on the first mounting base 51. A horizontally extending track 511 is formed on the first mounting base 51. The pressure head 1 is slidably assembled on the track 511 through the L-shaped mounting base. The first driving member 41 is assembled on the first mounting base 51. The first driving member 41 drives the L-shaped mounting base to drive the pressure head 1 to slide along the track 511.

[0049] As a preferred technical solution in this embodiment, the end of the pressure head 1 away from the support plate 2 is mounted on an L-shaped mounting base, and the end of the pressure head 1 near the support plate 2 has a stepped surface, which facilitates the mounting and positioning of the bearing 30.

[0050] As a preferred technical solution in this embodiment, the track 511 extends toward the support plate 2, and the pressure head 1 can move closer to or further away from the support plate 2 by moving along the track 511.

[0051] As a preferred technical solution in this embodiment, the first driving component 41 may be, but is not limited to, a hydraulic cylinder or a pneumatic cylinder.

[0052] As shown in Figure 5, the support plate 2 is horizontally slidably assembled. Specifically, the support plate 2 is horizontally slidably assembled to the second mounting base 52. The support plate 2 passes through the second mounting base 52 and slides horizontally along the second mounting base 52. The second driving member 42 drives the support plate 2 to slide horizontally.

[0053] As a preferred embodiment, as shown in Figure 6, the support plate 2 includes a front plate 21 and a rear plate 22 arranged at intervals and in parallel. The front plate 21 and the rear plate 22 are connected as a whole by multiple connecting rods 23. The connecting rods 23 pass through the second mounting base 52 and can slide horizontally along the second mounting base 52. The second driving member 42 is mounted on the second mounting base 52. The telescopic end of the second driving member 42 is connected to the front plate 21 to drive the support plate 2 to move. A through hole is formed on the rear plate 22 to facilitate the passage of the second driving member 42. Preferably, both the front plate 21 and the rear plate 22 are square plates, and there are four connecting rods 23, which are located at the four corners and connect the front plate 21 and the rear plate 22 respectively.

[0054] As a preferred technical solution of this embodiment, the second mounting base 52 includes a base 521 and a mounting plate 522. The mounting plate 522 is located on the base 521 and is vertically arranged. The connecting rod 23 passes through the mounting plate 522 and can slide with the mounting plate 522 through a linear bearing. The front plate 21 is located in front of the mounting plate 522 near the pressing position, and the rear plate 22 is located behind the mounting plate 522.

[0055] As a preferred technical solution of this embodiment, as shown in FIG7, a pad assembly 6 is further provided between the support plate 2 and the second mounting base 52 to facilitate support of the support plate 2 during press-fitting. The pad assembly 6 includes a pad 61 and a drive cylinder 62. The pad 61 is slidably mounted on the front surface of the mounting plate 522, and the drive cylinder 62 drives the pad 61 to slide along the mounting plate 522. Correspondingly, a support column 24 is provided on the surface of the front plate 21 facing the rear plate 22, and the support column 24 can abut against the pad 61 to achieve support. Preferably, the pad 61 has a clearance hole 611, and the mounting plate 522 has a through hole. When the support plate 2 retracts, the support column 24 can pass through the clearance hole 611 and the through hole to avoid interference; when support is required, the drive cylinder 62 drives the pad 61 to slide, and the support column 24 abuts against the pad 61 to achieve support. Multiple support columns 24 can be provided. In this embodiment, there are two support columns 24.

[0056] As a preferred technical solution in this embodiment, the second driving component 42 may be selected from, but is not limited to, a hydraulic cylinder or a pneumatic cylinder.

[0057] As shown in Figure 8, the support platform 3 is slidably mounted on the slide rail 53, and the support platform 3 can move along the slide rail 53 from the loading position to the pressing position. When the support platform 3 is in the loading position, it is convenient to load materials; when the support platform 3 moves to the pressing position, the pressing head 1 can press the workpiece 20.

[0058] As a preferred technical solution in this embodiment, there are two slide rails 53, which are parallel and spaced apart. The slide rails 53 extend in a straight line, and the bottom end of the support platform 3 slides along the slide rails 53 via a slider.

[0059] As a preferred technical solution in this embodiment, in order to limit the position of the support platform 3 at the loading position, a first limiting structure 71 is provided on one side of the slide rail 53 at the loading position. The first limiting structure 71 can block the support platform 3 to limit its position at the loading position. In order to lock the position of the support platform 3 at the loading position and prevent the position of the support platform 3 from changing during loading, a first locking structure 81 is also provided next to the first limiting structure 71. A corresponding slot 3121 is formed on the support platform 3, and the first locking structure 81 can extend into the slot 3121 to lock the support platform 3 at the loading position.

[0060] As a preferred technical solution in this embodiment, in order to limit the position of the support platform 3 at the pressing position, a second limiting structure 72 is provided on one side of the slide rail 53 at the pressing position. The second limiting structure 72 can block the support platform 3 to limit its position at the pressing position. In order to lock the position of the support platform 3 at the pressing position and prevent the position of the support platform 3 from changing during pressing, a second locking structure 82 is also provided next to the second limiting structure 72. The second locking structure 82 can extend into the slot 3121 to lock the support platform 3 at the pressing position. The second limiting structure 72 has the same structure as the first limiting structure 71, and the second locking structure 82 has the same structure as the first locking structure 81. Both the first locking structure 81 and the second locking structure 82 can be set as a cylinder-driven locking pin structure. When the support platform 3 moves to the point where it is blocked by the limiting structure, the corresponding locking structure can extend into the slot 3121 of the support platform 3 to lock the support platform 3.

[0061] As shown in Figures 9-10, the support platform 3 is used to support the workpiece 20. The workpiece 20 can rotate and slide when placed on the support platform 3. Specifically, the support platform 3 includes a base plate 31, a rotating plate 32, a sliding assembly 33, and a placement fixture 34. The rotating plate 32 is rotatably supported by the base plate 31. The placement fixture 34 is assembled onto the rotating plate 32 through the sliding assembly 33, and the workpiece 20 is placed on the placement fixture 34.

[0062] As shown in Figures 11-12, the rotary plate 32 is mounted on the base plate 31 via a rotary support 35. The rotary support 35 includes an inner ring and an outer ring that can rotate relative to each other. One of the inner ring and the outer ring is connected to the base plate 31, and the other is connected to the rotary plate 32.

[0063] As a preferred technical solution in this embodiment, a handle 311 is formed on the base plate 31 to facilitate gripping and pushing the support platform 3.

[0064] As a preferred technical solution of this embodiment, a first limiting block 312 is also formed on one side of the base plate 31. The first limiting block 312 is used to cooperate with the limiting structure and the locking structure. The first limiting block 312 can be blocked by the first limiting structure 71 and the second limiting structure 72 to achieve the limiting function. A slot 3121 is formed on the first limiting block 312. The first locking structure 81 and the second locking structure 82 can extend into the slot 3121 to lock the support platform 3.

[0065] As a preferred technical solution of this embodiment, as shown in Figures 11-12, in order to limit the position of the rotating plate 32, a limiting component is provided between the base plate 31 and the rotating plate 32 to limit the position of the rotating plate 32, facilitating the pressing head 1 to perform pressing. The limiting component includes a limiting member 36 mounted on the base plate 31 and a limiting groove 321 located on the outer peripheral surface of the rotating plate 32. The limiting member 36 elastically abuts against the outer peripheral surface of the rotating plate 32. When the limiting groove 321 moves to the position of the limiting member 36, the limiting member 36 can extend into the limiting groove 321 to form a limit. Specifically, the limiting member 36 can be a bearing, which is fixed to the mounting base by a fixing member. A sliding rod 361 is connected to the mounting base. A third mounting base 313 is provided on the upper surface of the base plate 31. The sliding rod 361 is slidably and limitingly mounted in the third mounting base 313. A spring 362 is sleeved on the sliding rod 361. One end of the spring 362 acts on the third mounting base 313, and the other end of the spring 362 acts on the mounting base, providing the limiting member 36 with a force that abuts against the outer circumferential surface of the rotating plate 32. Preferably, the two ends of the limiting groove 321 are inclined surfaces, which facilitates the limiting member 36 to disengage from the limiting groove 321. Preferably, there are two limiting grooves 321, which are evenly distributed. The arrangement of the two limiting grooves 321 allows the workpiece 20 to be rotated 180 degrees, thereby pressing the bearings 30 onto both ends of the workpiece 20.

[0066] As shown in Figures 13-14, the placement fixture 34 is assembled on the sliding assembly 33. The sliding assembly 33 includes a fixed plate 331 and a sliding plate 332. The fixed plate 331 is fixed on the rotary plate 32, and the sliding plate 332 is slidably assembled on the upper surface of the fixed plate 331. The placement fixture 34 is supported by the sliding plate 332.

[0067] As a preferred technical solution in this embodiment, in order to achieve positioning support for the workpiece 20, a limiting protrusion 341 is formed on the placement fixture 34. There are at least two limiting protrusions 341 to position the workpiece 20 on the placement fixture 34.

[0068] As a preferred embodiment, a second limiting block 342 is also formed on the fixture 34 to block and limit the workpiece 20. Specifically, the second limiting block 342 is located between the workpiece 20 and the support plate 2.

[0069] As a preferred embodiment, to limit the sliding direction of the sliding plate 332 relative to the fixed plate 331, two stops 3311 are formed at intervals on the upper surface of the fixed plate 331. The two stops 3311 are arranged in parallel, and both ends of the sliding plate 332 are slidably engaged with the two stops 3311 respectively. Thus, the sliding plate 332 can only slide along the extending direction of the two stops 3311. Preferably, the stops 3311 also extend to the upper surface of the sliding plate 332, which can hook the upper surface of the sliding plate 332 to prevent the sliding plate 332 from detaching from the fixed plate 331 from above.

[0070] As a preferred technical solution in this embodiment, when the workpiece 20 does not need to slide, the sliding assembly 33 can be locked. Specifically, at least one stop 3311 is equipped with a locking member 38, and the sliding plate 332 is provided with a locking groove. The locking member 38 can extend into the locking groove to lock the sliding plate 332. Specifically, the locking member 38 can be threaded onto the stop 3311, and rotating the locking member 38 can control the extension and retraction of the locking member 38.

[0071] As a preferred technical solution of this embodiment, in order to achieve automatic reset of the sliding plate 332, a reset assembly 37 is also provided on the fixed plate 331. There are at least two sets of reset assemblies 37, symmetrically distributed at both ends of the sliding direction of the sliding plate 332, providing a reset force for the sliding plate 332. Specifically, the reset assembly 37 includes a guide rod 371 and an elastic element 372. A mounting block 3312 is fixed on the fixed plate 331, and the guide rod 371 is fixed to the mounting block 3312. The guide rod 371 extends along the sliding direction of the sliding plate 332 and extends into the sliding plate 332, allowing the sliding plate 332 to slide along the guide rod 371. The elastic element 372 is sleeved on the guide rod 371, with one end of the elastic element 372 acting on the mounting block 3312 and the other end acting on the sliding plate 332. When the pressure head 1 is retracted after pressing, the sliding plate 332 can be reset to its initial position under the action of the reset assembly 37. The initial position of the sliding plate 332 can be set to the center position of the support platform 3.

[0072] As a preferred technical solution in this embodiment, the extension direction of the slide rail 53 is perpendicular to the sliding direction of the sliding plate 332 relative to the fixed plate 331, that is, the extension direction of the slide rail 53 is perpendicular to the extension and retraction direction of the pressure head 1 and the sliding direction of the pressure head 1 pushing the workpiece 20.

[0073] Based on the above structure, the press-fitting station in this embodiment presses the workpiece 20. The workpiece 20 can be an intermediate body with a dual-pump structure. A shaft hole is formed in the middle of the intermediate body, and bearings 30 need to be pressed into both ends of the shaft hole. The working process is as follows:

[0074] First, pull the handle 311 to move the support platform 3 to the loading position. The first limiting structure 71 blocks the support platform 3, and the first locking structure 81 locks the support platform 3. At this time, the workpiece 20 can be placed on the support platform 3, and the workpiece 20 is positioned by the limiting protrusion 341 on the tooling 34.

[0075] Then, after the workpiece 20 is loaded, the first locking structure 81 is unlocked, and the support platform 3 is pushed to the pressing position. The second limiting structure 72 blocks the support platform 3, and the second locking structure 82 locks the support platform 3. At this time, the limiting part 36 enters a limiting groove 321 to achieve the limiting. One end of the shaft hole of the workpiece 20 is directly facing the pressing head 1.

[0076] Then, a bearing 30 is fitted onto the pressure head 1, the support plate 2 is driven to extend by the second driving member 42, the driving cylinder 62 drives the pad 61 to slide between it and the support column 24 to form a support, the pressure head 1 slides horizontally under the driving action of the first driving member 41, the pressure head 1 presses the bearing 30 into one end of the shaft hole of the workpiece 20, during this process the workpiece 20 can slide through the sliding component 33 so as to more closely abut against the support plate 2.

[0077] Then, after pressing one end of the shaft hole of the workpiece 20 is completed, the press head 1 and the support plate 2 are retracted, and the rotary plate 32 is rotated so that the other limiting groove 321 of the rotary plate 32 is limited with the limiting member 36. At this time, the other end of the shaft hole of the workpiece 20 is facing the press head 1.

[0078] Finally, a bearing 30 is fitted onto the pressure head 1, the support plate 2 is extended by the second driving member 42, and the driving cylinder 62 drives the pad 61 to slide between it and the support column 24 to form a support. The pressure head 1 slides horizontally under the driving action of the first driving member 41, pressing the bearing 30 into the other end of the shaft hole of the workpiece 20. In this way, the bearings at both ends of the shaft hole of the workpiece 20 are press-fitted. During this process, the workpiece 20 can slide through the sliding component 33 to more tightly abut against the support plate 2.

[0079] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
