Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile seat parts detection, and particularly relates to a horizontal force detection tool for automobile seat slide rails. BACKGROUND

[0002] The upper and lower slide rails of an automobile seat may have a too large or too small gap after assembling a steel ball, resulting in loose or rough operation of the slide rails. Therefore, a force meter is needed to detect the pulling force when the upper and lower slide rails move relative to each other after assembling the steel ball. The qualified slide rail group then enters the next assembly and detection link. The existing technology uses a worker to pull the upper slide rail from the front end to the end by hand to measure whether the pulling force is in the qualified range. If the detection is unqualified, the size of the steel ball, the amount of lubricating oil or the viscosity needs to be adjusted. The disadvantages are that the worker cannot pull the upper slide rail uniformly and cannot accurately read the data on the force meter. The worker cannot ensure that the pulling force is horizontal and cannot accurately reflect the friction between the upper and lower slide rails and the steel ball. SUMMARY

[0003] The present application aims at the deficiency of the prior art, and develops a horizontal force testing fixture for automobile seat slide rail.

DETAILED DESCRIPTION

[0015] The invention will be further described in detail below in conjunction with the drawings and specific examples, and the specific examples described herein are only used to explain the invention and do not limit the invention.

[0016] As Figures 1 to 3As shown, the horizontal force testing tool for the automobile seat slide rail of the present application comprises a workbench 1, a bottom plate 2, a horizontal adjustment assembly 3, a slide rail force testing assembly 7, a plug-in rod assembly 12 and a lower slide rail fixing base 13. The horizontal adjustment assembly 3 comprises a ball head rod 4 and a ball head rod base 5. The ball head of the ball head rod 4 is placed in the ball head rod base 5. The lower end of the ball head rod 4 is fixedly connected with the workbench 1. The ball head rod base 5 is fixedly connected with the bottom plate 2. A threaded top rod 11 is threadedly connected with the ball head rod base 5. One end of the threaded top rod 11 can abut against the ball head of the ball head rod 4, and the other end of the threaded top rod 11 is connected with a first knob 6. The slide rail force testing assembly 7 comprises an electric slide rail set 8, a force gauge 9, a ball head pull rod 10 and the plug-in rod assembly 12. The electric slide rail set 8 comprises a motor 15, an electric upper slide rail 27, an electric lower slide rail 28 and a gear box 29. The electric upper slide rail 27 and the electric lower slide rail 28 are slidably connected. The motor 15 is connected with the gear box 29. The force gauge 9 is fixedly connected with the electric upper slide rail 27. The electric lower slide rail 28 is fixedly connected with the bottom plate 2. The plug-in rod assembly 12 comprises a connecting sheet 18, a plug-in rod 20, a lifting adjustment base 21 and an upper slide rail plug-in rod 24. The connecting sheet 18 is fixedly connected with the plug-in rod 20. A through hole 19 is formed in the connecting sheet 18. The lifting adjustment base 21 comprises a second knob 22 and a hollow threaded rod 23, which are concentrically connected. The hollow threaded rod 23 is threadedly connected with the upper slide rail plug-in rod 24. The plug-in rod 20 is inserted into the hollow threaded rod 23. The ball head pull rod 10 passes through the through hole 19. The ball headless end of the ball head pull rod 10 is hingedly connected with the force gauge 9. A positioning pin 14 is fixedly arranged in the lower slide rail fixing base 13. A first horizontal gauge 16 is fixedly arranged on the bottom plate 2. A second horizontal gauge 17 is fixedly arranged on the ball head pull rod 10.

[0017] Figure 3 As shown, the plug-in rod 20 is only used to show the matching relationship. In use, the plug-in rod 20 is completely inserted into the second knob 22 and the hollow threaded rod 23.

[0018] The electric slide rail set 8 used in the present application is a commercially available product. Its internal structure and working principle are known.

[0019] In the specific detection, first, as shown in Figure 4 , the worker places the to-be-detected upper slide rail 25 and the to-be-detected lower slide rail 26 preliminarily assembled with the steel ball in the lower slide rail fixing base 13. Figure 2 The positioning pin at the bottom of the lower slide rail fixing base 13 shown in the middle is used to fix the to-be-detected lower slide rail 26 in the horizontal direction, so that only the to-be-detected upper slide rail 25 can move horizontally during the detection. Subsequently, as shown in Figures 5 to 7 , the worker Figure 4The ball head pull rod 10 is placed horizontally, and the upper slide rail plug-in rod 24 at the lowermost part of the plug-in rod assembly 12 is inserted into the hole previously opened in the upper slide rail 25 to be detected. The worker adjusts the horizontal position of the base plate 2 and observes the first level meter 16. When the bubble in the first level meter 16 enters the mark ring, it indicates that the base plate 2 has been adjusted to the horizontal position, and the worker can tighten the first knob 6. The threaded jacking rod 11 pushes against the ball head of the ball head rod 4 to avoid changes in the position of the base plate 2 during the detection process. Subsequently, as shown in Figure 8 , the worker rotates the second knob 22, and it can be known that Figure 3 , the rotation of the second knob 22 can adjust the height of the lifting adjusting seat 21, and then adjust the ball head pull rod 10 to the horizontal position. At this time, the bubble in the second level meter 17 is between the two indication lines, which indicates that the ball head pull rod 10 is in the horizontal state, and the subsequent horizontal pulling force can be provided for the movement of the upper slide rail. Finally, as shown in Figure 9 , the worker operates the motor 15 of the electric slide rail group 8 to run (the motor 15 is shown in Figure 6 ), and the electric upper slide rail 27 moves to the right in the figure. The fixed load cell 9 connected thereto pulls the upper slide rail 25 through the ball head pull rod 10 and the plug-in rod assembly 12, and at this time, the load cell 9 detects the pulling force value. Comparing the pulling force value with the predetermined value can determine whether the slide rail is qualified. The qualified slide rail will enter the subsequent assembly link.

[0020] The electric slide rail group used in the present application is a commercially available product. The connection and matching relationship between the motor, the gear box, the electric upper slide rail, and the electric lower slide rail belong to the prior art.

[0021] The above description is only the preferred mode of the present application. It should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
