Description
Technical Field
[0001] The utility model relates to an assembly inspection tool for an automobile door glass lifter. Background Art
[0002] Car doors provide access for drivers and passengers to enter and exit the vehicle, isolate them from interference outside the vehicle, reduce side impacts to a certain extent, and protect occupants; car doors are equipped with door glass that can be raised and lowered, and the raising and lowering of the door glass depends on the lifter assembly installed in the door body; the lifter assembly is mainly composed of a traction part and a drive part. In order to ensure the outer contour dimensions of the lifter assembly and the accuracy of each hole used for installation and matching, the lifter assembly must be inspected with the help of a matching inspection fixture.
[0003] However, existing inspection fixtures for automobile door window lifter assemblies cannot simultaneously inspect both the traction and drive parts thereof. Instead, at least two sets of inspection fixtures must be manufactured and the inspection process must be carried out in two steps. First, the traction and drive parts of the window lifter assembly must be separated from each other. Then, the traction and drive parts must be separately and sequentially mounted on a matching inspection fixture for inspection. Finally, the traction and drive parts must be reassembled. Consequently, the inspection process is complex, and the disassembly and assembly of the traction and drive parts is both time-consuming and labor-intensive, resulting in low inspection efficiency. Furthermore, the need to manufacture two sets of inspection fixtures increases inspection costs, requiring further improvement. Utility Model Content

[0035] Working principle:
[0036] First, pull out each first detection pin 311, each reference pin 125 and each second detection pin 14; then move the handle of each first quick clamp 35, each second quick clamp 10 and each third quick clamp 122 so that their swing ends swing outward to the bottom; then move the movable end of the pulling mechanism 31 in each positioning assembly 3 in the direction away from the fixed clamp block 32, and then swing the swing end of the horizontal flipping mechanism 7 upward to drive the positioning column 8 away from the back plate 2; then lift the pressure rod 16 upward; the structures and principles of the detection pins, reference pins, quick clamps, pulling mechanism and horizontal flipping mechanism are all existing technologies.
[0037] Next, place the traction part of the glass lifter between the two positioning assemblies 3, and make the upper end of the traction part of the glass lifter be located between the dynamic clamping block 33 and the extension block 321 in the upper positioning assembly 3, and then make the lower end of the traction part of the glass lifter be located between the dynamic clamping block 33 and the extension block 321 in the lower positioning assembly 3, and then push the moving end of each pulling mechanism 31 toward the fixed clamping block 32, thereby driving the dynamic clamping block 33 to gradually approach the extension block 321, thereby clamping the upper and lower ends of the traction part of the glass lifter; at this time, the glass lifter is located between the dynamic clamping block 33 and the extension block 321 in the lower positioning assembly 3. The bosses at the upper and lower ends of the glass lifter traction part are respectively inserted into the positioning sleeves 310 in the two positioning assemblies 3; then, the handles of the two first quick clamps 35 are toggled to drive the first pressure blocks 37 to move toward the glass lifter traction part with the help of their swinging ends until the ends of the two extension bars 372 on each first pressure block 37 are pressed against the outer wall of the glass lifter traction part; then, the positioning column 8 is driven to swing backward with the help of the swinging end of the horizontal turning mechanism 7 until its end is pressed against the outer wall of the glass lifter traction part; in this way, the fixing of the glass lifter traction part is completed.
[0038] Next, place the driving part of the glass lifter on the first limit seat 11, each second limit seat 123, and each third limit seat 13; then, move the handle of the third quick clamp 122 in each reference module 12 to drive the second pressure block 126 to swing toward the direction of the glass lifter driving part with its swinging end until the end of the second pressure block 126 is pressed against the outer wall of the glass lifter driving part; then, swing the pressure rod 16 downward so that the end of the protrusion 161 on it is pressed against the outer wall of the glass lifter driving part; this completes the fixing of the glass lifter driving part.
[0039] Afterwards, each first detection pin 311 is passed through the corresponding through hole located in the glass lifter drive part and between the two extension strips 372 and inserted into a corresponding detection sleeve 39, and then each reference pin 125 is passed through the corresponding reference hole located in the glass lifter drive part and the corresponding second limiting groove 1261 and inserted into a corresponding reference sleeve 124, and then each second detection pin 14 is passed through the corresponding mounting hole located in the glass lifter drive part and inserted into a corresponding third limiting seat 13, so as to determine whether the hole position, hole spacing and hole diameter values of each through hole, reference hole and mounting hole in the glass lifter drive part are qualified.
[0040] Finally, turn the knobs of each first dial indicator 5 and each second dial indicator 6 so that their detection ends move toward the traction part of the glass lifter until the detection ends of each first dial indicator 5 and each second dial indicator 6 are tightly pressed against the outer wall of the traction part of the glass lifter, and then use the dial indicator to accurately determine whether the numerical value of the external contour dimension of the traction part of the glass lifter is qualified.
[0041] The utility model only needs one inspection fixture to simultaneously inspect the traction part and the driving part of the automobile door glass lifter assembly, thereby eliminating the operation of disassembling and assembling the traction part and the driving part, thereby simplifying the inspection steps to achieve the effect of saving time and labor and improving the inspection efficiency, and also eliminating the need to make two sets of inspection fixtures to reduce the inspection cost.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
