Description

Technical Field

[0001] The utility model relates to an assembly tool for automobile parts, in particular to an assembly tool for a clamp ring of a seat pan frame of an automobile. Background Art

[0002] In the process of automobile seat production, the assembly of clamp rings is an important part of the automobile seat frame. The existing clamp ring assembly tooling is generally driven by a hydraulic cylinder and consists of a hydraulic pump, a hydraulic cylinder, a control valve and other components. The hydraulic pump pressurizes the oil and transports it to the hydraulic cylinder through a pipeline. The piston in the hydraulic cylinder pushes the clamping plate or fixture under the action of the oil to achieve clamping or loosening operations. Although the driving force of the hydraulic system is large, the assembly using a hydraulic mechanism has the following defects:

[0003] 1. The oil in the hydraulic system may leak due to damage to the pipeline or seals, which will cause environmental pollution, oil loss and system pressure drop, affecting the clamping effect;

[0004] 2. The performance of oil is greatly affected by temperature. High temperature may cause the viscosity of oil to decrease, affecting the working efficiency and accuracy of the system; low temperature may make the oil too viscous, resulting in difficulty in starting and slow response speed;

[0005] 3. The hydraulic system will generate certain noise during operation;

[0006] 4. The entire assembly mechanism occupies too large an area.

DETAILED DESCRIPTION

[0024] In order to make the technical scheme and technical effect of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments.

[0025] like Figure 1-2 As shown, the utility model provides a car seat pan frame clamp ring assembly tool, including a workbench 100, a pre-installation mechanism 110, a servo transmission mechanism 120 and a wedge-shaped lifting mechanism 130 are arranged on the horizontal surface of the workbench 100, specifically:

[0026] The pre-installation mechanism 110 is arranged along the length direction of the workbench 100, and the seat basin frame is pre-installed at both axial ends of the pre-installation mechanism 110. The pre-installation mechanism 110 includes a base 111, a rear pipe clamping cylinder 113 and a pressure head 112. The base 111 is provided with a first U-shaped groove at two opposite edges along the length direction of the workbench 100, and a steel pipe penetrating the seat basin frame is arranged in the first U-shaped groove; the rear pipe clamping cylinder 113 and the pressure head 112 are rotatably connected, and the pressure head 112 presses the steel pipe and pops open as the wedge-shaped lifting mechanism 130 descends into place.

[0027] The servo transmission mechanism 120 is symmetrically arranged with respect to the pre-installation mechanism 110 and has gaps at both axial ends of the pre-installation mechanism 110. The servo transmission mechanism 120 includes a servo motor 121, an electric cylinder 122, a rivet head seat slide 123 and a slide rail 124. A clamping ring rivet head is axially extended from the rivet head seat slide 123. The servo motor 121 drives the electric cylinder 122 to move axially to drive the rivet head seat slide 123 to move toward each other along the slide rail 124 to press the clamping ring, which is arranged on the clamping ring rivet head. Compared with the traditional hydraulic system, the servo transmission mechanism 120 can provide high-precision position control and has a fast response speed. It can quickly adjust the output to adapt to the changes in the input signal, thereby realizing fast and accurate control. The working principle of the servo transmission mechanism 120 is common knowledge in the art and will not be elaborated here.

[0028] The wedge-shaped lifting mechanism 130 is placed below the pre-installation mechanism 110. The wedge-shaped lifting mechanism 130 can move up and down to convert the vertical force into horizontal displacement to clamp the clamping ring. The wedge-shaped lifting mechanism 130 includes a wedge block 131 and a lifting assembly 132, wherein the contact surface between the lifting assembly 132 and the wedge block 131 is in an arc shape, and the wedge block 131 is horizontally displaced with the lifting movement of the lifting assembly 132. Due to the characteristics of the wedge structure, it can realize the positioning and clamping of the clamping ring by using a simple inclined surface and force conversion without using a complex mechanical device. Such a design can not only simplify the assembly process, but also improve the assembly accuracy and efficiency.

[0029] like Figure 3-4 As shown, the wedge block 131 has a first inclined surface 1310 and a second inclined surface 1311, wherein a second U-shaped groove is provided in the vertical direction in the middle of the first inclined surface 1310 to fix the steel pipe, and the second inclined surface 1311 contacts the outer surface of the lifting assembly 132. Preferably, the top of the lifting assembly 132 is a semicircular structure.

[0030] The workbench 100 further includes a control cabinet 140 and a start button 150 . The control cabinet 140 is located vertically below the workbench 100 . The start button 150 is electrically connected to the control cabinet 140 to start the operation of the servo transmission mechanism 120 .

[0031] Although the application of the servo transmission mechanism 120 is relatively common, in the present invention, the pre-installation mechanism 110 and the wedge-shaped lifting mechanism 130 are used to achieve precise positioning of the clamping ring, which has a faster response speed and improves the assembly efficiency of the clamping ring of the car seat pan frame.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
