Description

Technical Field

[0001] This utility model belongs to the field of seat technology, specifically relating to a tooling for assembling a seat chassis and a handle. Background Technology

[0002] The office chair base, also known as a swivel chair base or swivel chair tray, is an important component located under the seat cushion of a swivel chair or office chair. The seat height adjustment and backrest tilt adjustment are all achieved through the base. The base typically consists of a main body and a handle mounted on the side of the base. The chair's tilt is adjusted by moving the handle.

[0003] In existing technologies, due to the complexity of the connection between the chassis and its accessory handles, most assembly work still relies on manual operation, such as hammering installation using tools like rubber rods. The assembly process between the chassis and handles is particularly delicate and requires a very high level of manual skill. There are strict requirements regarding the magnitude and direction of the force applied to the handles. This not only limits production efficiency but also increases manufacturing costs. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a tooling for assembling a seat chassis and a handle, so as to solve the technical problem of low assembly efficiency between the seat base and the handle.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] A tooling for assembling a seat chassis and a handle includes a frame, a machining platform, and two sets of pressing assemblies.

[0007] The processing platform is equipped with a clamping component. The seat chassis is mounted on the processing platform and can be locked in position by the clamping component.

[0008] The two sets of pushing components are respectively arranged on both sides of the processing platform. The pushing component includes a locking block and a pushing cylinder. The locking block is fixed on the telescopic end of the pushing cylinder and can move to one side of the processing platform under the drive of the pushing cylinder to achieve the clamping and fixing of the handle pre-fixed on the seat chassis to the seat chassis.

[0009] Furthermore, each of the aforementioned pushing components is provided with a folding and storage assembly between itself and the frame. The folding and storage assembly includes a storage platform and a flipping drive component. The storage platform is hinged to the frame. The flipping drive component is mounted on the frame, and its outer end is connected to the storage platform to achieve the flipping and folding of the storage platform.

[0010] Furthermore, the clamping assembly includes two side clamping blocks and multiple positioning clamping blocks. The two side clamping blocks are symmetrically arranged on both sides of the processing platform and slide in engagement with the processing platform. Each positioning clamping block is spaced apart on one side of the processing platform and slides in engagement with the processing platform. The sliding direction of the positioning clamping blocks is perpendicular to the sliding direction of the side clamping blocks.

[0011] Furthermore, the tilting drive is a telescopic cylinder. The tail end of the telescopic cylinder is hinged to the frame, and the telescopic end is hinged to the storage platform.

[0012] Furthermore, the storage platform is equipped with guide rails. Guide members that cooperate with the locking blocks are slidably mounted on the guide rails. The locking blocks are fixed to the top of the guide members.

[0013] Furthermore, the bottom of the frame is equipped with multiple casters.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This utility model achieves the clamping and fixing of the seat chassis by setting up a processing platform and cooperating with a clamping component. At the same time, a pushing component is set on both sides of the processing platform. Under the drive of the clamping block and the pushing cylinder in the pushing component, a stable clamping force in a specified direction is applied to the handle pre-fixed on the seat chassis. This ensures processing efficiency while avoiding damage to the final product and affecting the quality of the finished product due to incorrect pressure applied to the handle.

[0016] 2. This utility model provides a folding and storage component between the pressing component and the frame, which enables the pressing component to be folded and stored after the pressing component completes the processing operation, thereby facilitating the storage and organization of the assembly tooling.

[0022] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element 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 utility model.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, a tooling for assembling a seat chassis and a handle includes a frame 1, a processing platform 2, and two sets of pressing components 3. A clamping component 4 is provided on the processing platform 2. The seat chassis is mounted on the processing platform 2 and can be locked in position by the clamping component 4. The two sets of pressing components 3 are located on both sides of the processing platform 2. A folding and storage component 5 is provided between each set of pressing components 3 and the frame 1, allowing the pressing components 3 to be folded and stored after the processing operation is completed.

[0025] like Figure 2 As shown, the pressing assembly 3 includes a locking block 3-1 and a pressing cylinder 3-2. The locking block 3-1 is fixed to the telescopic end of the pressing cylinder 3-2 and can move towards the seat chassis side under the drive of the pressing cylinder 3-2, achieving a clamping fixation between the handle pre-fixed on the seat chassis and the seat chassis. The locking block 3-1 has a groove that mates with the handle. When the locking block 3-1 moves towards the processing platform 2 side under the push of the pressing cylinder 3-2, the outer end of the handle pre-fixed on the seat chassis enters the groove of the locking block 3-1 and is limited by the position of the groove. The pressing cylinder 3-2 continues to push the locking block 3-1 to move, achieving a clamping fixation between the handle and the seat chassis.

[0026] like Figure 3As shown, the folding and storage assembly 5 includes a storage platform 5-1 and a flipping drive component 5-2. The storage platform 5-1 is connected to the frame 1 via a hinge, enabling the storage platform 5-1 to be flipped and folded. The flipping drive component 5-2 is mounted on the frame 1, and its outer end is connected to the storage platform 5-1. When extended, the flipping drive component 5-2 pushes the storage platform 5-1 upwards until it is flush with the processing platform 2.

[0027] In this embodiment, the flipping drive component 5-2 is a telescopic cylinder. The tail end of the telescopic cylinder is hinged to the frame 1, and the telescopic end is hinged to the storage platform 5-1.

[0028] Furthermore, a guide rail 5-3 is provided on the storage platform 5-1. A guide member 5-4 that cooperates with the locking block 3-1 is slidably mounted on the guide rail 5-3. The locking block 3-1 is fixed to the top of the guide member 5-4, which can ensure the stability of the sliding trajectory under the constraint of the guide member 5-4 and prevent the direction of pressure applied by the locking block 3-1 from deviating during the process of pressing the handle.

[0029] like Figure 4 As shown, the clamping assembly 4 includes two side clamping blocks 4-1 and multiple positioning clamping blocks 4-2. The two side clamping blocks 4-1 are symmetrically arranged on both sides of the processing platform 2 and slide in engagement with it. When the side clamping blocks 4-1 slide to a designated position, they are locked in place by screws, thereby limiting the width of the subsequently installed seat chassis.

[0030] Each positioning block 4-2 is spaced apart on one side of the processing platform 2 and is slidably engaged with the processing platform 2. The sliding direction of the positioning block 4-2 is perpendicular to the sliding direction of the side block 4-1, and it can be locked by screws when it slides to a designated position, thereby limiting the position of the seat chassis in the length direction.

[0031] Furthermore, in this embodiment, the bottom of the frame 1 is provided with multiple casters 6, which facilitates the storage of the tooling after the assembly and processing of the seat chassis and handle are completed.

[0032] The working principle of this utility model:

[0033] In the initial state, the telescopic end of the flipping drive 5-2 retracts inward, causing the storage platform 5-1 to tilt downward to its limit position, facilitating the storage of the assembly tooling. When assembly processing is performed, the telescopic end of the flipping drive 5-2 extends outward, pushing the storage platform 5-1 to tilt upward until it is flush with the processing platform 2.

[0034] Next, adjust and lock the side locking blocks 4-1 and 4-2 to their designated positions. Place the seat chassis on the processing platform 2, with each side locking block 4-1 and 4-2 defining its position. Simultaneously, initially insert the handle into the adjusting rollers on both sides of the seat chassis. The push cylinder 3-2 pushes the locking block 3-1 towards one side of the seat chassis. The outer end of the handle, pre-fixed to the seat chassis, enters the slot of the locking block 3-1 and is positioned within the slot. The push cylinder 3-2 continues to push the locking block 3-1, achieving a tight clamping and fixing between the handle and the seat chassis.

[0035] After the assembly between the seat chassis and the handle is completed, the telescopic end of the push cylinder 3-2 retracts, causing the locking block 3-1 to move outward to its limit position, thereby making way for the intermediate processing platform 2, which facilitates the subsequent locking of the seat chassis.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
