Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical testing technology, and specifically relates to a gap detection mechanism. Background Technology
[0002] A car seat adjustment assembly is a device used to adjust the tilt angle of a seat, improving driving and passenger comfort. With the automotive industry's focus on energy conservation, emission reduction, and the development of new energy vehicles, people's demands for car seat comfort are increasing. As the core component of the seat adjustment assembly, the accuracy of the assembly clearance of the adjuster is a crucial factor to consider during the design and manufacturing process. Due to the inherent tolerances of the cover itself, there are deviations between the assembly center of the cover and the corresponding parts. Currently, clearance inspection is primarily done manually; however, this method is inefficient and relies heavily on operator skill, easily leading to errors. Therefore, accurately and quickly determining the axial clearance between the cover and the adjuster has become a key technical problem that needs to be solved. Utility Model Content
[0003] This invention provides a gap detection mechanism that can quickly detect the axial gap of products that are assembled using the same principle as the toothed plate and sheath of an angle adjuster, laying the foundation for assisting in monitoring the yield rate of the final product.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] The gap detection mechanism includes a contouring base placed on an operating table. A wedge-shaped cylinder for clamping the product is provided on one side of the contouring base. A clamping component is provided above the contouring base, and a detection component is provided below the contouring base. The detection end of the detection component extends upward into the contouring base. A wedge-shaped gripper is connected to the wedge-shaped cylinder, and the wedge-shaped gripper is coaxial with the center of the contouring base.
[0006] Preferably, the clamping assembly includes a clamping cylinder and a clamping block connected to the cylinder shaft of the clamping cylinder.
[0007] Preferably, a sensor for monitoring the presence or absence of a product is also provided on one side of the contouring base.
[0008] Preferably, the detection component includes a displacement sensor and a detection head disposed on the displacement sensor, the upper end of the detection head extending into a linear bearing inside the contouring machine base.
[0009] Preferably, the detection components are arranged in three groups with gaps in a circumferential distribution, with each group consisting of two adjacent groups. In each group of detection components, one detection head is placed below the protective sleeve, and another detection head is placed below the toothed plate of the angle adjuster.
[0010] The beneficial effects of this utility model are reflected in the following: This mechanism can realize the axial gap detection between products based on the same principle as the assembly between the toothed plate and the sheath of the angle adjuster. By setting multiple sets of detection components, gap detection at different positions can be performed, making the detection results more accurate. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided in conjunction with the appendix. Figures 1-4 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0017] This utility model proposes a gap detection mechanism, including a contouring base 11 placed on an operating table 1. In this embodiment, the gap between the toothed plate of the angle adjuster and the protective sleeve is taken as an example. The contouring base 11 includes a base plate and a contouring block placed on the base plate. A spring is also provided between the contouring block and the base plate so that the product can be floated and adjusted when placed on the contouring block.
[0018] One side of the contouring base 11 is provided with a wedge-shaped cylinder 4 for clamping the product 6 and a sensor 3 for monitoring the presence or absence of the product. A wedge-shaped gripper is connected to the wedge-shaped cylinder 4, and the wedge-shaped gripper is coaxial with the center of the contouring base 11. The wedge-shaped gripper can clamp the product placed on the contouring base 11 for more stable positioning.
[0019] A clamping assembly is provided above the contouring base 11. The clamping assembly includes a clamping cylinder 2 and a clamping block 21 connected to the cylinder shaft of the clamping cylinder 2. When the clamping cylinder 2 operates, it drives the clamping block 21 to clamp the upper part of the product, so that the product remains stable in the height direction.
[0020] A detection assembly is disposed below the contouring base 11; the detection end of the detection assembly extends upward into the contouring base 11. The detection assembly includes a displacement sensor 5 and a detection head 51 disposed on the displacement sensor 5, the upper end of the detection head 51 extending into the linear bearing 12 inside the contouring base 11. In this embodiment, the detection assembly is arranged in three groups with gaps in a circumferential distribution, two adjacent to each other as a group. In each group of detection assemblies, one detection head is placed below the protective sleeve, and one detection head is placed below the angle adjuster tooth plate, specifically below the angle adjuster at the connection with the protective sleeve. Of course, the number of groups of detection assemblies can be adjusted and set as needed.
[0021] During testing, one detection head 51 in the same group abuts against the bottom of the sheath, while the other detection head 51 abuts against the bottom of the adjuster toothed plate. The axial clearance value between the adjuster toothed plate and the sheath is obtained by comparing the values acquired by the displacement sensors corresponding to the two detection heads. Whether the clearance value is within the acceptable range determines whether the product meets the requirements. This improves testing speed, reduces labor costs, and significantly increases the efficiency of clearance testing, making it highly practical. Of course, this invention can also be applied to clearance testing between other components assembled using the same principle.
