The device adjusts the leveling base using a hydraulic leveling component, ensuring the leveling base is parallel to the horizontal positioning surface. This guarantees that the axis of the flexible cotter pin is perpendicular to the horizontal positioning surface after passing through the pressing guide. Adjusting the position of the mounting base within the horizontal plane ensures that the axis of the flexible cotter pin is coaxial with the pressing hole after passing through the pressing guide. This ensures the pressing positioning accuracy of the flexible cotter pin and the final pressing assembly quality. The flexible cotter pin is guided by a guide cone sleeve in the pressing guide. External pressure is applied to the flexible cotter pin by controlling the deformation amount, thus controlling the deformation amount of the flexible cotter pin during the pressing assembly process. A centering cylindrical sleeve limits the movement of the flexible cotter pin, ensuring that its axis is coaxial with the axis of the pressing hole. Ultimately, this ensures that the flexible cotter pin is pressed and assembled with an appropriate amount of deformation.

Description

Technical Field

[0001] This invention belongs to the technical field of flexible cotter pin assembly, and relates to a flexible cotter pin pressing device and pressing method. Background Technology

[0002] Resilient cotter pins are commonly used positioning parts. In existing technologies, the installation of resilient cotter pins typically involves directly stamping them with a pressure head, using the pressure to press the cotter pin into the pressing hole on the part. However, since the diameter of the resilient cotter pin is usually larger than the diameter of the pressing hole, a relatively large pressure is required to ensure its smooth entry. Excessive pressure can lead to excessive deformation of the cotter pin, while insufficient pressure makes it difficult to press it into place properly. Furthermore, in existing technologies, directly pressing the cotter pin with a pressure head makes it difficult to ensure that the axis of the cotter pin is perpendicular to the mounting surface of the pressing hole, and also makes it difficult to guarantee the coaxiality between the axis of the cotter pin and the axis of the pressing hole. This often results in substandard installation quality of the resilient cotter pins.

[0003] Therefore, in view of the above-mentioned technical problems existing in the pressing and assembly process of elastic cotter pins in the prior art, the present invention discloses an elastic cotter pin pressing device and pressing method thereof. Summary of the Invention

[0004] The purpose of this invention is to provide a flexible cotter pin pressing device and pressing method, which can ensure that the axis of the flexible cotter pin is perpendicular to the mounting surface of the pressing hole and that the axis of the flexible cotter pin is coaxial with the axis of the pressing hole, thereby pressing and assembling the flexible cotter pin with appropriate pressure and stroke, effectively controlling the deformation of the flexible cotter pin during the pressing and assembly process, and ultimately ensuring the pressing and assembly quality of the flexible cotter pin.

[0005] This invention is achieved through the following technical solution:

[0006] A flexible cotter pin pressing device includes a pressing part positioning device. The top of the pressing part positioning device is provided with a horizontal positioning surface. A mounting base is slidably arranged on the horizontal positioning surface. The mounting base has an inner cavity. A leveling base is floatingly arranged in the inner cavity. Hydraulic leveling components are provided between the edge of the upper end face of the leveling base and the upper cavity wall of the inner cavity, and between the edge of the lower end face of the leveling base and the lower cavity wall of the inner cavity. A pressing guide is provided at the center of the leveling base, and a pressing head is provided above the pressing guide.

[0007] The horizontal positioning surface at the top of the pressing part positioning device serves as a positioning reference surface. The pressing part is clamped and fixed by the device to prevent movement during the pressing process. A mounting base capable of sliding within the horizontal plane is provided on the horizontal positioning surface. The sliding of the mounting base adjusts the coaxiality between the pressing guide on the leveling base and the pressing hole of the pressing part. Simultaneously, the hydraulic leveling assembly adjusts the levelness between the leveling base and the horizontal positioning surface, ensuring the leveling base remains parallel to the horizontal positioning surface. This guarantees that the axis of the pressing guide on the leveling base is perpendicular to the horizontal positioning surface, allowing the elastic cotter pin to be pressed into the pressing hole at the top of the pressing part while maintaining its axis perpendicular to the horizontal positioning surface. Furthermore, the pressing guide guides the pressing process of the elastic cotter pin and limits its deformation.

[0008] To better realize the present invention, the hydraulic leveling assembly further includes a hydraulic mandrel, a connecting rod, and a tilt sensor. A plurality of hydraulic mandrels are provided on the upper cavity wall of the inner cavity at the edge of the upper end face of the leveling base and on the lower cavity wall of the inner cavity at the edge of the lower end face of the leveling base. The push rod end of the hydraulic mandrel is hinged to the edge of the upper end face or the edge of the lower end face of the leveling base through the connecting rod. The tilt sensor is provided on the leveling base to detect the tilt angle of the leveling base relative to the horizontal positioning surface.

[0009] To better realize the present invention, the pressing guide further includes a guide cone sleeve, a deformation control elastic sleeve, and a centering cylindrical sleeve that are coaxially connected in sequence. The guide cone sleeve is used to guide the elastic cotter pin, the deformation control elastic sleeve is used to squeeze the outer side of the elastic cotter pin to control the deformation of the elastic cotter pin, and the centering cylindrical sleeve is used to limit the final deformation of the elastic cotter pin.

[0010] To better realize the present invention, the deformation control elastic sleeve further includes an outer fixed sleeve and an inner elastic sleeve. The inner elastic sleeve is coaxially arranged inside the outer fixed sleeve. A hydraulic cavity is formed between the outer wall of the inner elastic sleeve and the inner wall of the outer fixed sleeve. The hydraulic cavity is provided with an inlet and an outlet.

[0011] To better realize the present invention, the mounting base further includes an upper mounting base and a lower mounting base. The bottom of the upper mounting base is provided with an upper cavity, and the top of the lower mounting base is provided with a lower cavity that is connected and assembled with the upper cavity to form an inner cavity. Hydraulic jacks are provided inside both the upper cavity and the lower cavity.

[0012] To better realize the present invention, a first sliding component that slides along a first direction is provided on the horizontal positioning surface, a second sliding component that slides along a second direction is provided on the sliding end of the first sliding component, and a mounting base is provided on the sliding end of the second sliding component.

[0013] To better realize the present invention, the pressure head is further provided with an infrared centering laser, the top of the pressing part positioning device is provided with a positioning groove, the inside of the positioning groove is provided with a part positioning fixture, and a pressure sensor is provided between the positioning groove and the positioning fixture.

[0014] A method for pressing elastic cotter pins, based on an elastic cotter pin pressing device, includes the following steps:

[0015] Step 1: Fix the pressing parts on the horizontal positioning surface at the top of the pressing parts positioning device;

[0016] Step 2: Adjust the tilt angle of the leveling base using the hydraulic leveling assembly so that the tilt angle between the leveling base and the horizontal positioning surface is less than or equal to 0.02°.

[0017] Step 3: Detect the relative coaxial position between the pressing guide and the pressing part using the infrared centering laser on the pressure head. Control the sliding of the mounting seat according to the coaxial position until the coaxiality error between the pressing guide and the pressing part is less than or equal to 0.01mm.

[0018] Step 4: The pressure head drives the elastic cotter pin to press down. The pressure head uses a first pressure to drive the elastic cotter pin to press down for a first stroke, and then the pressure head uses a second pressure to drive the elastic cotter pin to press down for a second stroke to complete the pressing.

[0019] To better realize the present invention, further, the first pressure is less than or equal to three-quarters of the calibrated pressure when the elastic cotter pin undergoes a preset deformation, the second pressure is less than or equal to one-half of the calibrated pressure when the elastic cotter pin undergoes a preset deformation, and the first stroke is greater than or equal to one-half of the overall pressing stroke.

[0020] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0021] (1) The present invention adjusts the levelness of the leveling base by means of a hydraulic leveling component, so that the leveling base is parallel to the horizontal positioning surface, ensuring that the axis of the pressing guide is perpendicular to the horizontal positioning surface, and thus ultimately ensuring that the axis of the elastic cotter pin is perpendicular to the horizontal positioning surface after passing through the pressing guide; at the same time, the present invention adjusts the position of the mounting base in the horizontal plane so that the axis of the pressing guide is coaxial with the axis of the pressing hole of the pressing part, thus ultimately ensuring that the axis of the elastic cotter pin is coaxial with the pressing hole after passing through the pressing guide; thus ensuring the pressing positioning accuracy of the elastic cotter pin and the final pressing assembly quality.

[0022] (2) The present invention guides the elastic cotter pin by means of the guide cone sleeve in the pressing guide, applies external pressure to the elastic cotter pin by means of the deformation amount control, controls the deformation amount of the elastic cotter pin in the pressing assembly process, limits the elastic cotter pin by means of the centering cylindrical sleeve, ensures that the axis of the elastic cotter pin is coaxial with the axis of the pressing hole, and ultimately ensures that the elastic cotter pin is pressed and assembled with appropriate deformation amount.

[0023] (3) The present invention uses a pressure sensor to detect the axial pressure on the elastic cotter pin during the pressing and assembly process in real time, and controls the pressure applied to the elastic cotter pin by the pressure head and the axial stroke that drives the elastic cotter pin to move by the feedback axial pressure, so as to ensure that the elastic cotter pin can be pressed and assembled with a suitable stroke under the action of a suitable pressure, and effectively avoid the occurrence of deformation or incomplete pressing of the elastic cotter pin.

Detailed Implementation

[0029] The following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0030] 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 scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is intended to include the plural form as well. 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.

[0031] For ease of description, the words "up," "down," "left," and "right" appearing in this invention only indicate that they are consistent with the up, down, left, and right directions of the accompanying drawings themselves, and do not limit the structure. They are merely for the purpose of facilitating the description of this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Terminology Explanation: The terms "installation," "connection," "linking," and "fixing" in this invention should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction relationship between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1:

[0033] This embodiment provides a flexible cotter pin pressing device, such as... Figures 1-4 As shown, the device includes a pressing part positioning device 1. The top of the pressing part positioning device 1 is provided with a horizontal positioning surface. A mounting base 2 is slidably arranged on the horizontal positioning surface. An inner cavity 3 is provided inside the mounting base 2. A leveling base 4 is floatingly arranged in the inner cavity 3. A hydraulic leveling component 5 is provided between the edge of the upper end face of the leveling base 4 and the upper cavity wall of the inner cavity 3, and between the edge of the lower end face of the leveling base 4 and the lower cavity wall of the inner cavity 3. A pressing guide 7 is provided at the center of the leveling base 4, and a pressing head 6 is provided above the pressing guide 7.

[0034] The pressing part positioning device 1 includes a positioning base and a positioning clamp. The top of the positioning base is provided with a positioning groove, and the positioning clamp is provided on the side wall of the positioning groove. The pressing part is placed inside the positioning groove, and the side of the pressing part is clamped and fixed by the positioning clamp to achieve positioning and fixation of the pressing part and prevent the pressing part from moving during the subsequent pressing process.

[0035] The top of the positioning base is provided with a horizontal positioning surface, which is parallel to the horizontal plane. A mounting base 2, capable of translating within the horizontal plane, is provided on the horizontal positioning surface. An inner cavity 3 is provided at the center of the mounting base 2, and a leveling base 4 is located within the inner cavity 3. A pressing guide 7 is located at the center of the leveling base 4. The parallelism of the leveling base 4 relative to the horizontal positioning surface is adjusted by the hydraulic leveling assembly 5, ensuring that the leveling base 4 remains parallel to the horizontal positioning surface, thereby guaranteeing that the axis of the pressing guide 7 is perpendicular to the horizontal positioning surface.

[0036] Under the premise of ensuring that the axial direction of the pressing guide 7 is perpendicular to the horizontal positioning surface, the mounting base 2 is moved in the horizontal plane to make the axis of the pressing guide 7 coaxial with the axis of the pressing hole of the pressing part. Then, the pressing head 6 can drive the elastic cotter pin downward to perform the pressing operation. During the pressing of the elastic cotter pin, the pressing guide 7 guides the elastic cotter pin and limits its deformation, so that the elastic cotter pin remains coaxial with the pressing hole and performs pressing with an appropriate amount of deformation, thereby ensuring the pressing quality between the elastic cotter pin and the pressing hole. Example 2:

[0037] This embodiment provides an elastic cotter pin pressing device and its pressing method, which are improvements based on Embodiment 1, such as... Figure 3 and Figure 4 As shown, the hydraulic leveling assembly 5 includes a hydraulic mandrel 51, a connecting rod 52, and a tilt sensor. Several hydraulic mandrels 51 are provided on the upper cavity wall of the inner cavity 3 at the edge of the upper end face of the leveling base 4 and on the lower cavity wall of the inner cavity 3 at the edge of the lower end face of the leveling base 4. The push rod end of the hydraulic mandrel 51 is hinged to the edge of the upper end face or the edge of the lower end face of the leveling base 4 through the connecting rod 52. The tilt sensor is provided on the leveling base 4 to detect the tilt angle of the leveling base 4 relative to the horizontal positioning surface.

[0038] The tilt angle of the leveling base 4 relative to the horizontal positioning surface is detected by the tilt sensor, and the detected tilt angle data is sent to the external controller. The external controller adjusts the extension of the hydraulic jack 51 in real time according to the tilt angle data, and then drives the leveling base 4 to float through the connecting rod 52 until the leveling base 4 is parallel to the horizontal positioning surface.

[0039] The other parts of this embodiment are the same as those in Embodiment 1, so they will not be described again. Example 3:

[0040] This embodiment provides an elastic cotter pin pressing device and its pressing method, which are improvements based on Embodiment 1 or 2, such as... Figure 3 and Figure 4 As shown, the pressing guide 7 includes a guide cone sleeve 71, a deformation control elastic sleeve 72, and a centering cylindrical sleeve 73, which are coaxially connected in sequence. The guide cone sleeve 71 is used to guide the elastic cotter pin. The deformation control elastic sleeve 72 is used to squeeze the outer side of the elastic cotter pin to control the deformation of the elastic cotter pin. The centering cylindrical sleeve 73 is used to limit the final deformation of the elastic cotter pin.

[0041] The diameter of the top end of the guide cone sleeve 71 is greater than the diameter of the bottom end of the guide cone sleeve 71, and the diameter of the top end of the guide cone sleeve 71 is greater than the outer diameter of the elastic cotter pin. The guide cone sleeve 71 guides the pressed elastic cotter pin to ensure that the elastic cotter pin can smoothly enter the deformation control elastic sleeve 72.

[0042] After the elastic cotter pin passes through the guide cone sleeve 71 and enters the deformation control elastic sleeve 72, the external controller controls the elastic sleeve 72 to compress the elastic cotter pin according to the preset deformation amount. The applied external pressure controls the deformation amount of the elastic cotter pin within a suitable range. Then, the elastic cotter pin continues to be pressed down into the centering cylindrical sleeve 73. The centering cylindrical sleeve 73 centers and limits the elastic cotter pin, keeping its axis perpendicular to the horizontal positioning surface and pressing it into the pressing hole of the pressing part.

[0043] Furthermore, the deformation control elastic sleeve 72 includes an outer fixed sleeve 721 and an inner elastic sleeve 722. The inner elastic sleeve 722 is coaxially arranged inside the outer fixed sleeve 721. The outer wall of the inner elastic sleeve 722 and the inner wall of the outer fixed sleeve 721 form a hydraulic cavity. The hydraulic cavity is provided with an inlet and an outlet.

[0044] The inlet is connected to the inlet device via an inlet pipe, and the outlet is connected to the outlet device via an outlet pipe. When liquid enters through the inlet, the pressure inside the hydraulic chamber increases, which in turn squeezes the inner elastic sleeve 722. This causes the inner elastic sleeve 722 to contract and further squeeze the elastic cotter pin. The amount of deformation of the elastic cotter pin is controlled by applying pressure to it. After compression is complete, liquid is discharged through the outlet, which reduces the pressure inside the hydraulic chamber. At this point, the inner elastic sleeve 722 expands under its own elasticity and no longer squeezes the elastic cotter pin.

[0045] The other parts of this embodiment are the same as those in Embodiment 1 or 2, so they will not be described again. Example 4:

[0046] This embodiment provides an elastic cotter pin pressing device and pressing method, which are improvements based on any one of embodiments 1-3, such as... Figure 2 As shown, the mounting base 2 includes an upper mounting base 21 and a lower mounting base 22. The bottom of the upper mounting base 21 is provided with an upper cavity, and the top of the lower mounting base 22 is provided with a lower cavity that is connected and assembled with the upper cavity to form an inner cavity. Both the upper cavity and the lower cavity are provided with hydraulic jacks 51.

[0047] The upper mounting base 21 is detachably fastened to the top of the lower mounting base 22. When maintenance or repair of the leveling base 4 and the pressing guide 7 is required, the upper mounting base 21 can be easily disassembled to perform maintenance or repair on the leveling base 4 and the pressing guide 7.

[0048] The other parts of this embodiment are the same as any one of embodiments 1-3, so they will not be described again. Example 5:

[0049] This embodiment provides an elastic cotter pin pressing device and pressing method, which is an improvement on any one of embodiments 1-4. A first sliding component that slides along a first direction is provided on the horizontal positioning surface, and a second sliding component that slides along a second direction is provided on the sliding end of the first sliding component. A mounting base 2 is provided on the sliding end of the second sliding component.

[0050] The first sliding assembly includes a first sliding seat, a first slide rail, a first slider, and a first driving device. The first sliding seat is slidably mounted on the first slide rail via the first slider. The first driving device is provided on one side of the first slide rail, and the first driving device drives the first sliding seat to slide along the first slide rail.

[0051] The second sliding assembly includes a second sliding seat, a second slide rail, a second slider, and a second driving device. The second sliding seat is slidably mounted on the second slide rail via the second slider. A second driving device is provided on one side of the second slide rail, which drives the second sliding seat to slide along the second slide rail.

[0052] Through the sliding engagement of the first sliding component and the second sliding component, the axis of the pressing guide 7 is quickly adjusted to move to a position coaxial with the axis of the pressing hole of the pressing part, thereby ensuring that the axis of the elastic cotter pin is coaxial with the axis of the pressing hole for pressing operations.

[0053] The other parts of this embodiment are the same as any one of embodiments 1-4, so they will not be described again. Example 6:

[0054] This embodiment provides an elastic cotter pin pressing device and pressing method, which is an improvement on any one of embodiments 1-5. The pressing head 6 is equipped with an infrared centering laser, the top of the pressing part positioning device 1 is provided with a positioning groove, the inside of the positioning groove is provided with a part positioning fixture, and a pressure sensor is provided between the positioning groove and the positioning fixture.

[0055] The coaxiality between the axis of the pressure head 6, the axis of the pressing guide 7, and the axis of the pressing hole can be detected in real time using an infrared centering laser. The pressure sensor can detect the pressure when the elastic cotter pin is pressed into the pressing hole in real time, and then adjust the pressure applied by the pressure head 6 to the elastic cotter pin and the downward stroke based on the feedback pressure, thereby controlling the deformation of the elastic cotter pin within a suitable range.

[0056] The other parts of this embodiment are the same as any one of embodiments 1-5, so they will not be described again. Example 7:

[0057] A method for pressing a resilient cotter pin, implemented based on the resilient cotter pin pressing device according to any one of claims 1-7, includes the following steps:

[0058] Step 1: Fix the pressing parts on the horizontal positioning surface at the top of the pressing parts positioning device 1;

[0059] Step 2: Adjust the tilt angle of the leveling base 4 using the hydraulic leveling component 5 so that the tilt angle between the leveling base 4 and the horizontal positioning surface is less than or equal to 0.02°.

[0060] Step 3: Detect the relative coaxial position between the pressing guide 7 and the pressing part using the infrared centering laser on the pressing head 6. Control the sliding of the mounting base 2 according to the coaxial position until the coaxiality error between the pressing guide 7 and the pressing part is less than or equal to 0.01mm.

[0061] Step 4: The pressure head 6 drives the elastic cotter pin to press down. The pressure head 6 uses the first pressure to drive the elastic cotter pin to press down for the first stroke, and then the pressure head 6 uses the second pressure to drive the elastic cotter pin to press down for the second stroke to complete the pressing.

[0062] Furthermore, the first pressure is less than or equal to three-quarters of the calibrated pressure when the elastic cotter pin undergoes a preset deformation, the second pressure is less than or equal to one-half of the calibrated pressure when the elastic cotter pin undergoes a preset deformation, and the first stroke is greater than or equal to one-half of the overall pressing stroke.

[0063] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
