Description

Technical Field

[0001] This utility model relates to the field of automotive assembly tooling technology, and more specifically, to a handle mounting and dismounting device for a brake hand valve. Background Technology

[0002] In existing technologies, for a brake hand valve with a separate valve body and handle assembly structure, the connection between the handle and the valve body linkage is typically secured by two locating pins during the assembly of the instrument panel assembly. While this method structurally ensures a stable connection between the handle and the valve body, it faces several significant challenges in practical operation. First, the locating pins and the mounting holes on the handle have an interference fit, making the assembly of the locating pins quite difficult, especially during manual assembly. Precise positioning and sufficient force are required to overcome the resistance of the interference fit, exceeding the capabilities of manual operation, resulting in low assembly efficiency and difficulty in guaranteeing assembly quality. Second, existing assembly tools often fail to ensure the locating pins are fully installed because they lack effective positioning and limiting mechanisms. Operators need to attempt multiple times to ensure the locating pins are correctly inserted, which not only increases assembly time but may also damage the handle surface due to improper operation, affecting the product's appearance and quality. Finally, when the handle needs to be disassembled for maintenance or replacement, because the locating pins are fully embedded in the handle holes, it is difficult to safely remove them using traditional tools, and the handle or locating pins are easily damaged during disassembly, increasing maintenance costs and difficulty.

[0003] No effective solution has yet been proposed to address the aforementioned technical issues. Utility Model Content

[0004] The main purpose of this utility model is to provide a handle assembly and disassembly device for a brake hand valve, so as to solve the problems of difficult assembly and disassembly of the positioning pin in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a handle assembly / disassembly device for a brake hand valve is provided. The handle assembly / disassembly device for a brake hand valve includes: a positioning assembly having a positioning state that surrounds at least a portion of the handle to be assembled / disassembled, the handle being assembled / disassembled being connected to a connecting rod within the valve body via a target positioning member; and a clamping assembly disposed opposite to the positioning assembly, the clamping assembly being movably connected relative to the positioning assembly, the clamping assembly having an assembly position that pushes the target positioning member a first preset distance along a preset direction to connect the target positioning member to the connecting rod within the valve body, and a disassembly position that pushes the target positioning member a second preset distance along a preset direction to disengage the target positioning member from the handle to be assembled / disassembled.

[0006] Furthermore, the second preset distance is set to be greater than the first preset distance.

[0007] Furthermore, the clamping assembly includes an assembly assembly and a disassembly assembly. When one of the assembly assembly and the disassembly assembly is in a working position, the assembly assembly and the disassembly assembly are positioned opposite to the positioning assembly. The assembly assembly and the disassembly assembly are movably connected relative to the positioning assembly. The assembly assembly has an assembly position, and the disassembly assembly has a disassembly position.

[0008] Furthermore, the handle mounting and dismounting device for the brake hand valve also includes: a frame structure having a receiving space with an opening on one side, a positioning component, a clamping component, and a handle to be mounted or dismounted located within the receiving space, the positioning component being connected to one inner wall of the frame structure, and the clamping component being located on the other side of the inner wall of the frame structure; and a drive component that can pass through the side wall of the frame structure and be connected to the clamping component, the drive component being used to drive the clamping component to be in the mounting position and the dismounting position.

[0009] Furthermore, the clamping assembly also includes a connecting block, which is connected to the drive assembly and is connected to the inner wall of the frame structure by fixing bolts.

[0010] Furthermore, both the assembly assembly and the disassembly assembly include: a clamping body, one end of which is detachably connected to a connecting block, and threadedly connected to a drive assembly, the drive assembly being used to drive the assembly assembly to an assembly position and to drive the disassembly assembly to a disassembly position, the clamping body being slidably connected relative to the positioning assembly.

[0011] Furthermore, the clamping body has an arc-shaped mating surface, and a first protective pad is provided on the surface of the arc-shaped mating surface. A lifting structure is provided on the first protective pad, wherein the height of the lifting structure provided on the assembly component is different from the height of the lifting structure provided on the disassembly component.

[0012] Furthermore, the distance by which the height of the lifting structure on the assembly component exceeds the surface of the first protective pad is 'a', and the distance by which the height of the lifting structure on the disassembly component exceeds the surface of the first protective pad is 'b', wherein 2mm≤a≤3mm and 7mm≤b≤8mm.

[0013] Furthermore, the side wall of the positioning component is provided with a first guide member, and the side wall of the clamping body is provided with a second guide member, and the first guide member and the second guide member are slidably connected.

[0014] Furthermore, the positioning component has an arc-shaped mating surface on the side facing the handle to be installed or removed, and a second protective pad is provided on the arc-shaped mating surface.

[0015] By applying the technical solution of this utility model, the synergistic action of the positioning component and the clamping component enables the handle to be assembled or disassembled to be precisely and securely connected to the connecting rod inside the valve body via the target positioning component. When the handle to be assembled or disassembled needs to be assembled, the positioning component surrounds at least a portion of the handle to be assembled or disassembled, ensuring its correct position. The clamping component then pushes the target positioning component to a first preset distance along a preset direction, so that the positioning component is fully embedded, thereby securely connecting the handle to be assembled or disassembled to the connecting rod inside the valve body. During disassembly, the clamping component pushes the target positioning component to a second preset distance along the same preset direction, so that the target positioning component is partially or completely detached from the handle to be assembled or disassembled, facilitating the disassembly of the handle. This achieves fast and safe assembly and disassembly of the handle to be assembled or disassembled, improves assembly efficiency, ensures assembly quality, and avoids scratches on the surface of the parts by tools. It solves the problems of inaccurate positioning and difficulty in controlling clamping force during traditional assembly and disassembly processes, which lead to assembly difficulties and damage to parts.

[0036] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0037] It should be noted that the application scenarios of this utility model device are as follows: instrument panel assembly station on the production line, cab assembly in the trial production workshop, disassembly of hand valves required for modifying and replacing internal parts of the cab instrument panel, and maintenance and parts replacement at service stations.

[0038] Combination Figures 1 to 3 As shown, according to a specific embodiment of the present invention, a handle mounting and dismounting device for a brake hand valve is provided.

[0039] Specifically, such as Figure 1 As shown, a handle assembly / disassembly device for a brake hand valve includes: a positioning assembly 10, which has a positioning state that surrounds at least a portion of the handle 100 to be assembled / disassembled, the handle 100 being assembled / disassembled being connected to a connecting rod within a valve body 200 via a target positioning member 300; and a clamping assembly 20, which is disposed opposite to the positioning assembly 10 and is movably connected to the positioning assembly 10. The clamping assembly 20 has an assembly position that pushes the target positioning member 300 a first preset distance in a preset direction so that the target positioning member 300 drives the handle 100 to be assembled / disassembled to connect with the connecting rod within the valve body 200, and a disassembly position that pushes the target positioning member 300 a second preset distance in a preset direction so that the target positioning member 300 disassembles from the handle 100 to be assembled / disassembled.

[0040] In this embodiment, through the synergistic action of the positioning component 10 and the clamping component 20, the handle 100 to be installed or removed can be precisely and securely connected to the connecting rod inside the valve body 200 via the target positioning member 300. When it is necessary to assemble the handle 100 to be installed or removed, the positioning component 10 surrounds at least a portion of the handle 100 to be installed or removed, ensuring its correct position; the clamping component 20 then pushes the target positioning member 300 to a first preset distance along a preset direction, so that the target positioning member 300 is fully embedded, thereby securely connecting the handle 100 to be installed or removed and the valve body 20. The connecting rod within 0; during disassembly, the clamping assembly 20 pushes the target positioning part 300 along the same preset direction to a second preset distance, so that the target positioning part 300 is partially or completely detached from the handle to be assembled or disassembled 100, which facilitates the disassembly of the handle to be assembled or disassembled 100, realizes the quick and safe assembly and disassembly of the handle to be assembled or disassembled 100, improves assembly efficiency, ensures assembly quality, and avoids scratches on the surface of the parts by tools. It solves the problems of inaccurate positioning and difficulty in controlling clamping force in the traditional assembly and disassembly process, which lead to assembly difficulties and damage to parts.

[0041] Among them, the target positioning component 300 is set as a positioning pin.

[0042] Furthermore, the second preset distance is set to be greater than the first preset distance, ensuring that the positioning pin is completely disengaged during the disassembly process.

[0043] like Figure 2 As shown, the clamping assembly 20 includes an assembly assembly 21 and a disassembly assembly 22. When one of the assembly assembly 21 and the disassembly assembly 22 is in the working position, the assembly assembly 21 and the disassembly assembly 22 are disposed opposite to the positioning assembly 10. The assembly assembly 21 and the disassembly assembly 22 are movably connected relative to the positioning assembly 10. The assembly assembly 21 has an assembly position, and the disassembly assembly 22 has a disassembly position.

[0044] Specifically, the assembly component 21 and the disassembly component 22 are interchangeable, eliminating the need for different special tools and reducing production costs. Since the assembly component 21 and the disassembly component 22 can be movably connected relative to the positioning component 10, the magnitude and direction of the force can be precisely controlled during assembly or disassembly, avoiding damage to the handle 100 to be assembled or disassembled and the target positioning component 300 due to improper application of force, while also ensuring the accuracy of assembly and the smoothness of disassembly.

[0045] Furthermore, the handle mounting and dismounting device for the brake hand valve also includes: a frame structure 30, which has a receiving space with an opening on one side, wherein the positioning component 10, the clamping component 20, and the handle 100 to be mounted or dismounted are located within the receiving space, the positioning component 10 is connected to one inner wall of the frame structure 30, and the clamping component 20 is located on the other side of the inner wall of the frame structure 30; and a drive component 40, which can pass through the side wall of the frame structure 30 and be connected to the clamping component 20, and the drive component 40 is used to drive the clamping component 20 to be in the mounting position and the dismounting position.

[0046] Specifically, the frame structure 30 provides a semi-enclosed working environment, ensuring the stability of the positioning component 10 and the clamping component 20 during operation, thus improving the overall structural stability and operational reliability of the device. The drive component can adjust the position of the clamping component 20 to tighten or release the handle 100 to be installed or removed.

[0047] In this embodiment, the positioning component 10 is fixedly connected to one side inner wall of the frame structure 30 by the first bolt 101. In other embodiments, the positioning component 10 can also be bonded, welded, or integrally formed to one side inner wall of the frame structure 30.

[0048] In some alternative embodiments, a fine-tuning device, such as a microswitch, can be added to achieve more precise position control.

[0049] Furthermore, the clamping assembly 20 also includes a connecting block 23, which is connected to the drive assembly 40 and is connected to the inner wall of the frame structure 30 by fixing bolts.

[0050] Specifically, the connecting block 23 serves as a bridge between the drive assembly 40 and the assembly assembly 21 or disassembly assembly 22. The connecting block 23 is connected to the frame structure via the second bolt 102, ensuring the stable transmission of the driving force of the drive assembly 40.

[0051] Furthermore, both the assembly assembly 21 and the disassembly assembly 22 include: a clamping body 211, one end of which is detachably connected to the connecting block 23 and threadedly connected to the drive assembly 40, the drive assembly 40 being used to drive the assembly assembly 21 to the assembly position and to drive the disassembly assembly 22 to the disassembly position, the clamping body 211 being slidably connected to the positioning assembly 10.

[0052] Specifically, the detachable connection design of the clamping body 211 of the assembly component 21 and the connecting block 23 with the disassembly component 22, and the threaded connection with the drive component 40, allows the operator to quickly replace different clamping bodies 211 as needed. This provides smooth and controllable movement, facilitating precise adjustment of the clamping force and preventing excessive pressure or damage to parts during assembly or disassembly, thus ensuring operational accuracy and safety. The sliding connection of the clamping body 211 relative to the positioning component 10, combined with the precise control of the drive component 40, ensures stable positioning of the handle 100 to be assembled or disassembled during assembly and disassembly, reducing operational errors and improving assembly efficiency and product quality.

[0053] Furthermore, the clamping body 211 has an arc-shaped mating surface, and a first protective pad 212 is provided on the surface of the arc-shaped mating surface. A lifting structure 213 is provided on the first protective pad 212. The height of the lifting structure 213 provided on the assembly component 21 is different from the height of the lifting structure 213 provided on the disassembly component 22, which ensures the correct positioning and stable clamping of the handle during the assembly and disassembly process, while protecting the surface of the handle from damage.

[0054] Specifically, the lifting structure 213 set on the assembly component 21 is the first lifting structure 2131, and the lifting structure 213 set on the disassembly component 22 is the second lifting structure 2132. The first lifting structure 2131 and the second lifting structure 2132 are set at different heights.

[0055] In the above embodiments, the assembly component 21 includes a clamping body 211 and a first lifting element 2131, and the disassembly component 22 includes a clamping body 211 and a second lifting element 2132. During manufacturing, it is necessary to manufacture a set of assembly component 21 and a set of disassembly component 22 to meet the needs of use.

[0056] In another embodiment, a first lifting mechanism 2131 or a second lifting mechanism 2132 can be provided on the arc-shaped mating surface of the clamping body 211. Both the first lifting mechanism 2131 and the second lifting mechanism 2132 are detachable and replaceable. The driving assembly 40 drives the clamping body 211 to move along a preset direction, causing the first lifting mechanism 2131 to push the target positioning member 300 a first preset distance, so that the target positioning member 300 connects the handle 100 to be installed / removed to the connecting rod inside the valve body 200. Alternatively, the second lifting mechanism 2132 can push the target positioning member 300 a second preset distance, so that the target positioning member 300 disengages from the handle 100 to be installed / removed. That is, different lifting structures can be manufactured individually.

[0057] Based on the above embodiments, the lifting structure can also be configured to be retractable and positioned. Combined with an electric mechanism, the lifting structure can be pushed to different distances in different usage environments, and can be retractable to adjust different heights to meet the requirements.

[0058] Furthermore, the height of the lifting structure 213 on the assembly assembly 21 exceeds the surface of the first protective pad 212 by a distance a, and the height of the lifting structure 213 on the disassembly assembly 22 exceeds the surface of the first protective pad 212 by a distance b, wherein 2mm≤a≤3mm and 7mm≤b≤8mm.

[0059] The height of the lifting structure 213 on the assembly assembly 21 is set to exceed the surface of the first protective pad 212 by a distance a of 2mm to 3mm. This ensures accurate alignment and assembly of the target positioning part 300 (i.e., the positioning pin) with the mounting hole inside the handle, while avoiding excessive pressure that could damage the handle or the positioning pin. The height of the lifting structure 213 on the disassembly assembly 22 is set to exceed the surface of the first protective pad 212 by a distance b of 7mm to 8mm. This provides sufficient space for the positioning pin to be extruded, allowing it to enter the positioning assembly 10. This facilitates its removal from the positioning assembly 10 using pliers or other tools, avoiding excessive pressure on the handle surface during disassembly and reducing damage.

[0060] Furthermore, the side wall of the positioning component 10 is provided with a first guide 11, and the side wall of the clamping body 211 is provided with a second guide 214. The first guide 11 and the second guide 214 are slidably connected.

[0061] In one embodiment, the first guide member 11 is configured as a guide groove, and the second guide member 214 is configured as a guide rod, wherein the guide rod and the guide groove are configured to cooperate with each other.

[0062] In another embodiment, the first guide member 11 is configured as a guide rod, and the second guide member 214 is configured as a guide groove, with the guide rod and the guide groove being configured to cooperate with each other.

[0063] like Figure 3 As shown, the positioning component 10 has an arc-shaped mating surface on the side facing the handle 100 to be installed or removed, and a second protective pad 12 is provided on the arc-shaped mating surface. Positioning holes 13 are provided on the arc-shaped mating surface and the second protective pad of the positioning component 10. The position of the positioning hole 13 corresponds to the position of the target positioning component 300. The depth of the positioning hole 13 is 7mm, and the diameter is 3mm. When the driving component 40 drives the disassembly component 22 to push the target positioning component 300 a second preset distance, the target positioning component 300 moves from the inside of the handle 100 to be installed or removed into the positioning hole 13 of the positioning component 10, thereby separating and disassembling the handle 100 from the connecting rod of the valve body 200. The second protective pad 12 is made of rubber and is bonded to the arc-shaped mating surface.

[0064] In this embodiment, the drive assembly 40 includes: a connecting rod 41, which can pass through the side wall of the frame structure 30 and be threadedly connected to the clamping assembly 20; and a handle 42, which is connected to the connecting rod 41. By operating the handle 42, the connecting rod 41 is rotated, so that the clamping assembly 20 is moved toward the handle 100 to be installed or removed.

[0065] In other embodiments, the drive assembly 40 is provided with an electric structure, and a motor is connected to the connecting rod 41 to drive the connecting rod 41 to rotate, so that the clamping assembly 20 is moved toward the handle 100 to be installed or removed.

[0066] In another embodiment of this application, the principle of this utility model is as follows: When assembling the handle, firstly, the handle 100 to be assembled or disassembled is inserted into the valve body rod in the correct direction, and the two positioning pins (i.e., the target positioning parts 300) are pre-tightened (manually inserted a section). Secondly, the handle assembly / disassembly device of the brake hand valve is inserted into the handle 100 to be assembled or disassembled. The direction of the handle 100 to be assembled or disassembled and the relative direction of this device are referenced. Figure 1 As shown, the positioning component 10 and the side of the handle 100 to be installed or removed are then pressed tightly together. Since the mating surface of the positioning component 10 is consistent with the size and structure of the side of the handle 100 to be installed or removed, and the bottom of this device is also in contact with the dashboard trim cover, effective positioning can be achieved without movement. Then, the drive component 40 is tightened to the handle 100 to be installed or removed, so that the lifting structure of the assembly component 21 is in contact with the positioning pin. The drive component 40 is continued to tighten the handle 100 to be installed or removed until the side of the assembly component 21 and the handle 100 to be installed or removed are completely in contact, thus completing the installation. Finally, the tool is rotated in the opposite direction to tighten the handle 100 to be installed or removed, and the tool is removed.

[0067] When disassembling the handle, the assembly component 21 of this device is replaced with the disassembly component 22, whose boss height is 7mm higher than the rubber. The operation steps are the same as during assembly. Finally, the positioning pin is squeezed into the positioning hole 13 of the positioning component 10, and the positioning pin is removed with pliers.

[0068] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0069] 1. This device achieves a solution where installation and disassembly can be performed using a single tool through the simple interchangeability of the clamping and disassembly components, improving the convenience and versatility of tool use. At the same time, the threaded mechanism provides continuous and stable clamping force.

[0070] 2. This device includes a tool positioning and installation limiting mechanism, which can ensure that the installation is completed in one go, reducing the operator's workload and improving assembly efficiency; at the same time, the use of protective pads and raised structures avoids the impact of tools on the surface quality of parts and reduces damage to parts.

[0071] 3. This device has a simple overall structure, small size, light weight, flexible use, convenient handling, and easy maintenance, and can be used in a variety of working scenarios.

[0072] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.
