Description

Technical Field

[0001] This utility model belongs to the field of automotive seat manufacturing technology and relates to a tooling for assembling the pivot of the rear armrest of a seat. Background Technology

[0002] In the traditional assembly process of the rear seat armrest, it is usually necessary to perform pre-assembly manually, and then hold the parts by hand and use a torque gun to tighten the screw holes of the shaft. This method has the following drawbacks: (1) High dependence on manual operation: the product must be held by hand throughout the process, which is labor-intensive and inefficient; (2) Poor product consistency: manual operation is easily affected by human factors, resulting in uneven screw tightening force; (3) Insufficient production stability: it is impossible to guarantee the assembly accuracy of each product in mass production.

[0003] For example, patent CN113334308A provides an automotive seat armrest clamp assembly device. This device consists of a frame, an actuator, and a conveying mechanism, with the components connected by bolts. During operation, the workpiece is placed on a product placement plate, detected by a through-beam sensor, and then gripped by a robotic arm onto a clamping plate. A cylinder drives the clamping and positioning block to fix the workpiece, and the robotic arm moves the gripping arm to assemble the clamp. A camera detects any missing parts, and defective products are placed on a defective unloading rack. The advantages are a reasonable design, simple process, and it solves problems such as omissions and errors in manual assembly, improving production efficiency and yield. However, it relies on precision components, resulting in higher costs, greater maintenance difficulty, and weak adaptability to small-batch production.

[0004] Therefore, there is an urgent need for a tooling device that can achieve rapid tightening and reduce manual intervention in order to solve the above problems. Utility Model Content

[0005] To address the shortcomings of the existing technology, the purpose of this application is to provide a tooling for assembling the rear armrest hinge of a seat. This tooling utilizes an automated clamping structure to achieve rapid positioning and fixing of the product. This improves assembly efficiency, reduces manual handling, ensures consistent and stable screw tightening, reduces workload, and optimizes the production process.

[0006] Based on the above objectives, this application provides the following technical solution:

[0007] One of the technical solutions of this application provides a rear seat armrest pivot assembly fixture for quickly installing assembly parts on the armrest product.

[0008] The tooling includes the following structures: a clamping cylinder, a clamping mechanism, an upper substrate, a lower substrate, a handle, a switch, a support base, and a support frame.

[0009] The upper substrate is mounted on the lower substrate via a support frame; the clamping cylinder, clamping mechanism, switch, and support base are mounted on the upper substrate; the handle is mounted on the lower substrate.

[0010] Furthermore, the assembly parts include a pivot base and screws.

[0011] Furthermore, a support base is provided on the upper substrate, and the support base has a groove adapted to the shape of the handrail product for placing the handrail product to be assembled.

[0012] Furthermore, a clamping mechanism is provided below the support base, which is used to fix the rotating shaft base and the handrail product to be assembled.

[0013] Furthermore, the clamping mechanism is connected to the output end of the clamping cylinder. When the clamping cylinder applies force, it generates an inward force on the clamping mechanism, firmly fixing the handrail product to be assembled onto the tooling. The clamping mechanism consists of symmetrically arranged grippers. One end of each gripper is fixedly connected to the cylinder housing of the clamping cylinder, and the other end is used to press against the rotating shaft base. The cylinder housing and the cylinder piston rod are slidably connected, and the reciprocating motion of the cylinder housing is controlled by the increase or decrease of the internal gas.

[0014] Furthermore, a switch is provided on the upper substrate, which is connected to the input end of the clamping cylinder to control the operation of the clamping cylinder.

[0015] Furthermore, handles are provided on both sides of the lower substrate.

[0016] Furthermore, a limiting block is provided between the handrail product to be assembled and the pivot base. The pivot base and the handrail product to be assembled have corresponding screw holes for inserting screws.

[0017] Furthermore, the handrail product to be assembled is a foamed finished product.

[0018] Furthermore, the clamping cylinder, clamping mechanism, and support base are all axially symmetrically arranged, and their symmetrical planes are the same plane.

[0019] Furthermore, the height, shape, and specific assembly method of the support frame can be designed and adjusted according to actual usage. The support frame can integrate wiring, cylinder piping, batteries, etc.

[0020] Furthermore, the method of using the tooling is as follows:

[0021] First, place the handrail product to be assembled into the support base of the fixture and ensure it is in place. Place the two side limit blocks into the clamping mechanism. After confirming that the limit blocks are in place and the handrail product is not wobbling, insert the rotating shaft base. Press the switch; the equipment will automatically run and clamp. The operator then takes the assembly parts and fixes them in the corresponding screw holes. After the assembly parts are locked, confirm the status of the rotating shaft base, and then remove the handrail product with the assembled parts. The handrail product with the assembled parts then flows to the next process.

[0022] Compared with the prior art, the present invention has at least the following improvements and beneficial effects:

[0023] Firstly, by integrating pneumatic clamping mechanisms with automated control logic, semi-automatic operation of handrail pivot assembly is achieved, which greatly improves the level of automation, reduces direct human intervention in the assembly process, reduces defective products caused by human operation deviations (such as misalignment and uneven force) from the source, and effectively improves the product qualification rate.

[0024] Secondly, compared to traditional manual assembly, this tooling uses standardized positioning (support base, limit block) and mechanical force to drive clamping, ensuring that the assembly parameters of each batch of products are consistent, significantly improving product consistency and reducing subsequent use failures (such as abnormal noises and functional failures) caused by individual differences.

[0025] Third, it simplifies manual operation steps and shortens the assembly time of a single part. While improving production efficiency, it reduces the intensity of manual labor and manpower input. Long-term use can significantly save labor costs and adapt to the needs of large-scale production. Attached Figure Description

[0038] Example 1

[0039] like Figures 1-4 As shown, this embodiment provides a rear seat armrest pivot assembly fixture, including: a clamping cylinder 3, a clamping mechanism 4, an upper substrate 5-1, a lower substrate 5-2, a handle 6, and a switch 7. Figures 5-8 As shown, the armrest product 0 to be assembled is placed on a seat rear armrest pivot assembly fixture provided by this utility model, in preparation for the installation of assembly part 1; the assembly part 1 includes pivot base 1-1 and screw 1-2.

[0040] The connection relationships of the above parts are as follows:

[0041] The upper substrate 5-1 is mounted on the lower substrate 5-2 via a support frame 9. A support base 8 is provided on the upper substrate 5-1, which is used to place the handrail product 0 to be assembled.

[0042] A clamping mechanism 4 is provided below the support base 8. The clamping mechanism 4 is used to fix the rotating shaft base 1-1 and the handrail product 0 to be assembled. The clamping mechanism 4 is connected to the output end of the clamping cylinder 3. When the clamping cylinder 3 applies force, it generates an inward force on the clamping mechanism 4, so that the handrail product 0 to be assembled is firmly fixed on the tooling. A limit block 2 is provided at the contact part between the handrail product 0 to be assembled and the rotating shaft base 1-1. The function of the limit block 2 is to precisely limit the position of the handrail product 0 to be assembled within the clamping mechanism 4, to prevent it from shifting or shaking during the clamping process, to ensure that the contact position between the handrail product 0 and the clamping mechanism 4 is fixed and consistent, and to prevent excessive clamping force from causing the surface of the handrail product 0 to be deformed or damaged by pressure, thereby improving the accuracy of assembly positioning and the safety of the product.

[0043] The handrail product 0 to be assembled is a foamed product.

[0044] A handle 6 is also provided on the side edge of the lower substrate 5-2, which facilitates the operator to move or transport the entire tooling device, improving the convenience of operation. Especially when it is necessary to adjust the position of the device or move it to different work areas, the handle can be held to apply force stably, avoiding the inconvenience of operation or damage to components caused by direct contact with the substrate. A switch 7 is provided on the upper substrate 5-1. The working principle of the switch 7 is to control the on and off of the control circuit, thereby regulating the working state of the clamping cylinder 3 (such as starting with air supply or stopping with air supply cut off). When the switch is closed, the cylinder receives air power and drives the clamping mechanism 4 to move to fix the handrail product; when the switch is open, the cylinder stops working and the clamping mechanism is released, realizing flexible control of the assembly process.

[0045] Principle / Usage:

[0046] 1) First, place the handrail product 0 to be assembled in the tooling and ensure that the handrail product 0 is placed in the support seat 8; take the required limit blocks 2 on both sides and place them in the quick clamping mechanism 4; confirm that the limit blocks 2 on both sides of the clamping mechanism 4 are in place and that the handrail product 0 does not wobble; finally, install the rotating shaft base 1-1.

[0047] 2) After the product is placed, press the start switch 7. The equipment will then run automatically and clamp according to the design program. At this time, the operator can take the corresponding assembly part 1 and place it in the corresponding screw hole to fix it.

[0048] 3) After the assembly part 1 is locked, confirm the state of the product pivot base 1-1, and take out the assembled handrail product 0. The assembly part 1 has been installed on the handrail product 0.

[0049] The tooling provided by this invention can improve assembly efficiency by more than 30%, control positioning error within ±0.5mm, reduce manual operation intensity, reduce the risk of product surface scratches, and is suitable for mass production scenarios.

[0050] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
