Automobile seat slide rail horizontal force testing fixture

Abstract

This utility model relates to a horizontal force measuring tool for automotive seat slide rails, belonging to the field of automotive seat parts inspection. It includes a workbench, a base plate, a horizontal adjustment assembly, a slide rail force measuring assembly, a connecting rod assembly, and a lower slide rail fixing seat. The horizontal adjustment assembly includes a ball joint rod and a ball joint rod seat. The slide rail force measuring assembly includes an electric slide rail assembly, a force gauge, a ball joint pull rod, and a connecting rod assembly. The connecting rod assembly includes a connecting piece, a connecting rod, a lifting adjustment seat, and an upper slide rail connecting rod. The ball joint pull rod passes through a through hole, and its non-ball joint end is hinged to the force gauge. Because the horizontal adjustment assembly connects the workbench and the base plate, the base plate is kept horizontal. Combined with the adjustable connecting rod assembly, the tension on the upper slide rail is kept horizontal, ensuring the accuracy of the tension measurement. The use of an electric slide rail assembly with a force gauge replaces manual pulling of the upper slide rail, ensuring uniform tension and accurate data reading.

Description

Technical Field

[0001] This utility model relates to the field of automotive seat parts inspection, and in particular to an automotive seat slide rail horizontal force measuring tool. Background Technology

[0002] After steel balls are installed in the upper and lower rails of a car seat, the clearance between the three components may be too large or too small, causing the rails to run loosely or stiffly. Therefore, a force gauge is needed to test the tension between the upper and lower rails during relative movement after the steel balls are installed. Only rail assemblies that pass the test can proceed to the next assembly and testing stage. Current technology involves a worker manually pulling the upper rail from one end to the other using a force gauge to measure the tension value. If the test fails, the size of the steel balls, the amount of lubricating oil, or its viscosity needs to be adjusted. The shortcomings of this method are: the worker's manual pulling of the upper rail results in uneven tension and inaccurate readings on the force gauge; the worker's manual pulling creates an angle between the tension and the movement of the upper rail, making it impossible to ensure the tension is horizontal and accurately reflect the friction between the upper and lower rails and the steel balls. Summary of the Invention

[0003] This utility model addresses the shortcomings of existing technologies by developing a horizontal force measuring fixture for automotive seat slide rails. The technical solution adopted by this utility model is: a horizontal force measuring fixture for automotive seat slide rails, characterized by comprising a worktable 1, a base plate 2, a horizontal adjustment assembly 3, a slide rail force measuring assembly 7, a connecting rod assembly 12, and a slide rail fixing seat 13; the horizontal adjustment assembly 3 includes a ball joint rod 4 and a ball joint rod seat 5; the ball joint of the ball joint rod 4 is placed inside the ball joint rod seat 5; the lower end of the ball joint rod 4 is fixedly connected to the worktable 1; the ball joint rod seat 5 is connected to the base plate... 2.

[0004] The advantages of this utility model are as follows: by using a horizontal adjustment assembly connecting the workbench and the base plate, the base plate is ensured to be in a horizontal state. Combined with the plug rod assembly that can adjust the horizontal height, the pulling force on the upper slide rail is ensured to be in the horizontal direction, thus ensuring the accuracy of the pulling force detection. By using an electric slide rail assembly in conjunction with a force gauge to replace the worker's manual pulling of the upper slide rail, the pulling force is ensured to be uniform and the data reading is accurate.

[0018] The electric slide rail assembly 8 used in this utility model is a commercially available product, and its internal structure and working principle are known.

[0019] In specific testing, firstly, as... Figure 4 As shown, the worker places the pre-assembled steel ball upper slide rail 25 and lower slide rail 26, which are to be inspected, into the lower slide rail fixing seat 13. Figure 2 The locating pin at the bottom of the lower slide rail fixing seat 13 shown is used to fix the lower slide rail 26 to be inspected in the horizontal direction so that only the upper slide rail 25 to be inspected can move horizontally during inspection. Subsequently, as Figures 5 to 7 As shown, the worker will Figure 4The ball joint rod 10, which has been raised, is laid flat, allowing the lowermost upper slide rail connector rod 24 of the connector rod assembly 12 to be inserted into the pre-drilled hole on the upper slide rail 25 to be inspected. The worker adjusts the horizontal position of the base plate 2 and observes the first level gauge 16. When the bubble in the first level gauge 16 enters the gauge ring, it indicates that the base plate 2 has been adjusted to a horizontal position. The worker can then tighten the first knob 6, and the threaded push rod 11 will press against the ball head of the ball joint rod 4 to prevent the position of the base plate 2 from changing during the inspection process. Subsequently, as follows... Figure 8 As shown, the worker rotates the second knob 22, combining... Figure 3 It can be seen that rotating the second knob 22 can adjust the height of the lifting adjustment seat 21, thereby adjusting the ball head lever 10 to a horizontal position. At this time, the bubble in the second level gauge 17 is between the two indicator lines, indicating that the ball head lever 10 is in a horizontal state, and can subsequently provide horizontal pulling force for the movement of the upper slide rail. Finally, as Figure 9 As shown, the worker operates the motor 15 of the electric slide rail assembly 8 (motor 15 in...). Figure 6 As shown in the diagram, the electric upper slide rail 27 moves to the right. The fixed force gauge 9 connected to it pulls the upper slide rail 25 to the right via the ball joint rod 10 and the plug-in rod assembly 12. At this time, the force gauge 9 detects the tension value. By comparing this tension value with a predetermined value, it can be determined whether the slide rail is qualified. Qualified slide rails will proceed to the subsequent assembly stage.

[0020] The electric slide rail assembly used in this utility model is a commercially available product, and the connection and cooperation relationship between the motor, gearbox, electric upper slide rail, and electric lower slide rail are existing technologies.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the scope of protection of the present utility model.
