[0014] The method for measuring the height difference of the dual-track window regulator assembly, using the aforementioned dual-track window regulator assembly height difference detection device, is as follows:

[0015] Step 1: Place the guide rail I of the dual-track window regulator assembly on the base plate. Insert one pin on the guide rail I into the first positioning hole on the first positioning seat on the base plate. Rotate the first handle to rotate the first rotating rod fixedly connected to the first handle. The second connecting bolt fixedly connected to the first rotating rod moves until the first pressure block at the top of the first connecting bolt presses down on the guide rail I. Insert the other pin on the guide rail I into the second positioning hole on the connecting seat. Hold the second handle and rotate it to rotate the second rotating rod fixedly connected to it. The rotation of the second rotating rod causes the fixedly connected bracket to rotate. The bracket engages with the square pin on the guide rail I, thus stably fixing the guide rail I to the base plate.

[0016] Step 2: Place the guide rail II of the dual-track window lift assembly on the base plate, insert a pin on the guide rail II into the first positioning hole on the first positioning seat on the base plate, hold the first handle and rotate it, so that the first rotating rod fixedly connected to the first handle rotates, and the second connecting bolt fixedly connected to the first rotating rod moves until the first pressure block at the top of the first connecting bolt presses down on the guide rail II, thereby stably fixing the guide rail II on the base plate.

[0017] Step 3: Insert the dial indicator's column into the through hole on the left support base, rotate the set screw to fix the dial indicator on the support base, and then fix the dial indicator to the left fixed base. Insert the zero pin through the side block into the third positioning hole of the protrusion. At this time, the mark block on the protrusion is aligned with the zero position of the positioning scale on the side block, and then the entire moving base is at the theoretical zero position. Zero the dial indicator fixed on the fixed base. After zeroing, remove one end of the zero pin from the third positioning hole.

[0018] Step 4: The slider moves on the slide rail, and the movable seat fixedly connected to the slider moves. The movement of the movable seat causes the connecting block and the support block to move, and then the measuring rod sleeved on the support block abuts against the bracket on the guide rail I. The slider continues to move, causing the movable seat to move, and then the protrusion moves. The measuring rod of the dial indicator moves with the protrusion, and then the measuring value appears on the dial indicator, completing the inspection of the guide rail I.

[0019] Step 5: Insert the dial indicator's column into the through hole on the right support base, rotate the set screw to fix the dial indicator on the support base, and then fix the dial indicator to the left fixed base. Insert the zero pin through the side block into the third positioning hole of the protrusion. At this time, the mark block on the protrusion is aligned with the zero position of the positioning scale on the side block, and the entire moving base is in the theoretical zero position. Zero the dial indicator fixed on the fixed base. After zeroing, remove one end of the zero pin from the third positioning hole.

[0020] Step 6: The slider moves on the slide rail, and the movable seat fixedly connected to the slider moves. The movement of the movable seat causes the connecting block and the support block to move, and then the measuring rod sleeved on the support block abuts against the bracket on the guide rail II. The slider continues to move, causing the movable seat to move, and then the protrusion moves. The measuring rod of the dial indicator moves with the protrusion, and then the measuring value appears on the dial indicator, completing the inspection of the guide rail II.

[0021] Step 7: Subtract the measured values ​​from Step 4 and Step 6 to obtain the value M. If the absolute value of M is equal to 2mm, the height of the dual-track window regulator assembly meets the requirements; if the absolute value of M is not equal to 2mm, the height of the dual-track window regulator assembly does not meet the requirements.

[0022] Step 8: After completing the test, remove the dial indicator from the left and right mounting brackets, and place the dial indicator on the calibration pin to zero it.

[0023] Step 9: Pass the measuring rod of the dial indicator after zeroing in step 8 through the first Y guide hole, X guide hole, second Y guide hole and Z guide hole respectively, and make contact with the surfaces of guide rail I and guide rail II. After detection, read the value to complete the surface contour detection of the dual-rail window lift assembly.

[0024] Step 10: After the test is completed, place the dial indicator on the calibration pin, rotate the first lever to make the first rotating rod rotate, thereby moving the first connecting bolt and the first pressure block at the top of the first rotating rod, so that the first pressure block does not contact guide rail I and guide rail II; rotate the second lever to make the second rotating rod rotate, thereby moving the retainer at the top of the second rotating rod, and then separating the retainer from the square pin on guide rail I; remove the entire double-track window regulator assembly from the base plate.

[0025] The beneficial effects of this invention are:

[0026] The left and right brackets are equipped with sliding mechanisms on both sides. The dial indicator is zeroed by the zero pin to confirm the theoretical position of the bracket. The measuring rod on the sliding mechanism moves after contacting the bracket on guide rail I and guide rail II. The dial indicator detects the displacement of the sliding mechanism. The specific value of the deviation from the theoretical value is read by the dial indicator reading. The height is accurately measured by the difference between the two values. The measurement accuracy is higher and the after-sales risk of the double-track window lift assembly is reduced.

[0027] The first and second positioning holes engage with the pins on guide rails I and II to achieve positioning of guide rails I and II on the base plate. The rotatable first pressure block presses against guide rails I and II, and the rotatable bracket engages with the square pin on guide rail I to fix guide rails I and II on the base plate, so that guide rails I and II do not move during measurement, thus making the test data more accurate.

[0028] The measuring rod of the dial indicator is passed through the first Y-guide hole, X-guide hole, second Y-guide hole, and Z-guide hole respectively, and makes contact with the surfaces of guide rail I and guide rail II. After the test, the value is read to complete the surface profile test of the dual-rail window regulator assembly. This allows users to test the profile of the guide rails after the height test, making it convenient for use. Attached Figure Description

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0043] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0044] like Figure 1 , 2 As shown in Figures 8 and 10, the height difference detection device for the dual-track window regulator assembly includes a base plate 1. The base plate 1 is equipped with guide rails I 22 and II 23 for fixing the dual-track window regulator assembly, a first fixing component 4, and a second fixing component 5. (Refer to...) Figure 1In this embodiment, there are four first fixing components 4 and one second fixing component 5. Two first fixing components 4 are respectively located on the left and right sides of the base plate 1. A second fixing component 5 is located between the two first fixing components 4 on the left side. The two first fixing components 4 and the second fixing component 5 on the left side work to fix guide rail I 22, and the two first fixing components 4 on the right side fix guide rail II 23. Two fixing seats 9 are symmetrically arranged on the base plate 1. The fixing seats 9 are welded to the base plate 1, and each fixing seat 9 is equipped with a sliding mechanism. A measuring rod 19 is provided on the sliding mechanism. The two measuring rods 19 contact the brackets on guide rail I 22 and guide rail II 23 respectively. A detection component 6 is provided on the base plate 1. The detection component 6 includes a calibration pin 601 and a... The dial indicator 602 and calibration pin 601 are fixedly connected to the base plate 1. The measuring rod of the dial indicator 602 contacts the sliding mechanism. The dial indicator 602 is placed on the calibration pin 601 for zeroing. The dial indicator 602 is fixed on the fixed base 9. The displacement of the sliding mechanism is detected by the dial indicator 602. Specifically, the calibration pin 601 is provided with a placement groove. The dial indicator 602 is placed in the placement groove of the calibration pin 601 for zeroing. In use, the sliding mechanism drives the bracket to move on the guide rail I 22 and guide rail II 23, so that the measuring rod 19 moves with the displacement mechanism. Since the measuring rod 19 contacts the bracket, the bracket moves. The dial indicator 602 detects the displacement of the bracket, thereby realizing the detection of guide rail I 22 and guide rail II 23 respectively.

[0045] Reference Figure 8 The sliding mechanism includes a slide rail 10, a slider 11, a movable seat 12, a connecting block 16, and a support block 17. The slide rail 10 is fixedly connected to the fixed seat 9. The slider 11 is slidably connected to the slide rail 10. The movable seat 12 is fixedly connected to the slider 11. The movable seat 12 is provided with the connecting block 16. The connecting block 16 is provided with the support block 17. The measuring rod 19 is sleeved on the support block 17. The slider 11 moves on the slide rail 10, and the movable seat 12, which is fixedly connected to the slider 11, moves. The movement of the movable seat 12 causes the connecting block 16 and the support block 17 to move. Then, the measuring rod 19 sleeved on the support block 17 abuts against the brackets on the guide rail I 22 and the guide rail II 23. The slider 11 continues to move, causing the movable seat 12 to move. The dial indicator 602 is fixed on the fixed seat 9. The moving distance of the movable seat 12 is detected by the dial indicator 602, and a measurement value appears on the dial indicator 602.

[0046] Specifically, the fixed seat 9 has a threaded hole, and the bolt passes through the connecting hole of the slide rail 10 and connects with the threaded hole of the fixed seat 9; the slider 11 has a threaded hole, and the movable seat 12 has a connecting hole, and the bolt passes through the connecting hole of the movable seat 12 and connects with the threaded hole of the slider 11; the connecting block 16 has a connecting hole, and the movable seat 12 has a threaded hole, and the bolt passes through the connecting hole of the connecting block 16 and connects with the threaded hole of the movable seat 12; the support block 17 is L-shaped, one end of the support block 17 is connected to the connecting block 16, and the other end of the support block 17 is provided with a measuring rod 19; the fixed seat 9, the movable seat 12 and the connecting block 16 are all square blocks.

[0047] Reference Figure 8 The measuring rod 19 includes a sliding column 1901, a grip column 1902, and a contact column 1903. The sliding column 1901 is sleeved on the support block 17. The support block 17 has a through hole for the sliding column 1901 to slide. One end of the sliding column 1901 is fixedly connected to the grip column 1902, and the other end of the sliding column 1901 is fixedly connected to the contact column 1903. The contact column 1903 contacts the bracket. By gripping the grip column 1902, the sliding column 1901 moves on the support block 17, thereby adjusting the position of the contact column 1903, so that the contact column 1903 abuts against the bracket. Specifically, the diameters of the contact column 1903, the sliding column 1901, and the grip column 1902 increase sequentially, and the two sides of the grip column 1902 are milled flat to facilitate the movement of the grip column 1902 by hand.

[0048] Reference Figure 8 and Figure 12The movable seat 12 has a protrusion 1201 on its side, and the fixed seat 9 has a support 13. The protrusion 1201 contacts the support 13 and moves on the support 13. The support 13 enables the slider 11 to move stably on the slide rail 10. The dial indicator 602 is fixedly connected to the fixed seat 9 and abuts against the side of the protrusion 1201, thereby performing detection through the movement of the protrusion 1201. The support 13 has a side... Block 1301, with a zero-position pin 14 fitted on the side block 1301, is used to zero the dial indicator 602, facilitating the dial indicator 602 to detect the movement of the protrusion 1201.

In use, the zero-position pin 14 passes through the side block 1301 and is inserted into the third positioning hole 30 of the protrusion 1201. At this time, the marking block 29 on the protrusion 1201 is aligned with the zero position of the positioning ruler 28 on the side block 1301, and the entire moving seat 12 is in the theoretical zero position. The dial indicator 602 fixed on the fixed seat 9 is zeroed. After zeroing, one end of the zero-position pin 14 is removed from the third positioning hole 30, and then the dial indicator 602 is tested. Specifically, there are two limiting posts 15, which are respectively set on both sides of the support 13 and welded to the base plate 1. The movement of the protrusion 1201 is limited by the setting of the limiting posts 15, thereby limiting the movement of the slider 11, the moving seat 12, the connecting block 16, the support block 17 and the measuring rod 19. The marking block 29 is a triangular block. After one tip of the marking block 29 is aligned with the zero position of the positioning ruler 28, the entire moving seat 12 is in the theoretical zero position.

A limiting nut 20 is provided on one end of the vertical column 18, and the limiting nut 20 is threadedly connected to the vertical column 18. A limiting block 21 is provided on the other end of the vertical column 18. Rotating the limiting nut 20 causes it to move on the vertical column 18 until the limiting block 21 contacts the connecting block 16. At this time, the support block 17 is connected to the connecting block 16. In this embodiment, one end of the connecting block 16 is suspended on the moving seat 12, and the vertical column 18 is set on the side where the connecting block 16 is suspended.

[0060] The method for measuring the height difference of the dual-track window regulator assembly, using the aforementioned dual-track window regulator assembly height difference detection device, is as follows:

[0061] Step 1: Place the guide rail I22 of the dual-track window lift assembly on the base plate 1. Insert one pin on the guide rail I22 into the first positioning hole 409 on the first positioning seat 407 on the base plate 1. Rotate the first grip rod 404, causing the first rotating rod 403 fixedly connected to the first grip rod 404 to rotate. The second connecting bolt fixedly connected to the first rotating rod 403 moves until the first pressure block 406 at the top of the first connecting bolt 405 presses down on the guide rail I22. Insert the other pin on the guide rail I22 into the second positioning hole 509 on the connecting seat 507. Hold the second grip rod 504 and rotate it, causing the second rotating rod 503 fixedly connected to it to rotate. The rotation of the second rotating rod 503 causes the card seat 505 fixedly connected to it to rotate. The card seat 505 engages with the square pin on the guide rail I22, thus stably fixing the guide rail I22 on the base plate 1.

[0062] Step 2: Place the guide rail II 23 of the dual-track glass lifter assembly on the base plate 1, insert a pin on the guide rail II 23 into the first positioning hole 409 on the first positioning seat 407 on the base plate 1, hold the first grip rod 404 and rotate it, so that the first rotating rod 403 fixedly connected to the first grip rod 404 rotates, and the second connecting bolt fixedly connected to the first rotating rod 403 moves until the first pressure block 406 at the top of the first connecting bolt 405 presses down on the guide rail II 23, thereby stably fixing the guide rail II 23 on the base plate 1;

[0063] Step 3: Insert the column of dial indicator 602 into the through hole 25 on the left support 24, rotate the set screw 26 to fix dial indicator 602 on support 24, and then fix dial indicator 602 to the left fixed seat 9. Insert the zero pin 14 through the side block 1301 into the third positioning hole 30 of the protrusion 1201. At this time, the mark block 29 on the protrusion 1201 is aligned with the zero position of the positioning ruler 28 on the side block 1301, and then the entire moving seat 12 is at the theoretical zero position. The dial indicator 602 fixed on the fixed seat 9 is zeroed. After the zeroing is completed, remove one end of the zero pin 14 from the third positioning hole 30.

[0064] Step 4: The slider 11 moves on the slide rail 10, and the movable seat 12, which is fixedly connected to the slider 11, moves. The movement of the movable seat 12 causes the connecting block 16 and the support block 17 to move, and then the measuring rod 19 sleeved on the support block 17 abuts against the bracket on the guide rail I 22. The slider 11 continues to move, causing the movable seat 12 to move, and then the protrusion 1201 moves. The measuring rod of the dial indicator 602 moves with the protrusion 1201, and then the measuring value appears on the dial indicator 602, completing the inspection of the guide rail I 22.

[0065] Step 5: Insert the column of dial indicator 602 into the through hole 25 on the right support base 24, rotate the set screw 26 to fix dial indicator 602 on support base 24, and then fix dial indicator 602 to the left fixed base 9. Insert the zero pin 14 through the side block 1301 into the third positioning hole 30 of the protrusion 1201. At this time, the mark block 29 on the protrusion 1201 is aligned with the zero position of the positioning ruler 28 on the side block 1301, and then the entire moving base 12 is in the theoretical zero position. The dial indicator 602 fixed on the fixed base 9 is zeroed. After the zeroing is completed, remove one end of the zero pin 14 from the third positioning hole 30.

[0066] Step 6: The slider 11 moves on the slide rail 10, and the movable seat 12, which is fixedly connected to the slider 11, moves. The movement of the movable seat 12 causes the connecting block 16 and the support block 17 to move, and then the measuring rod 19 sleeved on the support block 17 abuts against the bracket on the guide rail II 23. The slider 11 continues to move, causing the movable seat 12 to move, and then the protrusion 1201 moves. The measuring rod of the dial indicator 602 moves with the protrusion 1201, and then the measuring value appears on the dial indicator 602, completing the inspection of the guide rail II 23.

[0067] Step 7: Subtract the measured values ​​from Step 4 and Step 6 to obtain the value M. If the absolute value of M is equal to 2mm, the height of the dual-track window regulator assembly meets the requirements; if the absolute value of M is not equal to 2mm, the height of the dual-track window regulator assembly does not meet the requirements.

[0068] Step 8: After completing the test, remove dial indicator 602 from the left and right mounting bases 9, and place dial indicator 602 on calibration pin 601 to zero it.

[0069] Step 9: Pass the measuring rod of the dial indicator 602, which was zeroed in step 8, through the first Y guide hole 205, the X guide hole 206, the second Y guide hole 305 and the Z guide hole 306 respectively, and make contact with the surfaces of guide rail I 22 and guide rail II 23. After detection, read the value to complete the surface contour detection of the dual-track window lift assembly.

[0070] Step 10: After the test is completed, place the dial indicator 602 on the calibration pin 601, rotate the first grip 404 to make the first rotating rod 403 rotate, thereby moving the first connecting bolt 405 and the first pressure block 406 at the top of the first rotating rod 403. The first pressure block 406 does not contact the guide rail I 22 and the guide rail II 23. Rotate the second grip 504 to make the second rotating rod 503 rotate, thereby moving the card seat 505 at the top of the second rotating rod 503, and then separating the card seat 505 from the square pin on the guide rail. Remove the entire double-track window lift assembly from the base plate 1.

The square pin on Ⅰ(22) is used to secure the guide rail Ⅰ(22) to the base plate (1); Step 2: Place the guide rail II (23) of the double-track glass lifter assembly on the base plate (1), insert a pin on the guide rail II (23) into the first positioning hole (409) on the first positioning seat (407) on the base plate (1), hold the first grip rod (404) and rotate it, so that the first rotating rod (403) fixedly connected to the first grip rod (404) rotates, and the second connecting bolt fixedly connected to the first rotating rod (403) moves until the first pressure block (406) at the top of the first connecting bolt (405) presses down the guide rail II (23), thereby stably fixing the guide rail II (23) on the base plate (1); Step 3: Insert the column of the dial indicator (602) into the through hole (25) on the left support base (24), rotate the set screw (26) to fix the dial indicator (602) on the support base (24), and then fix the dial indicator (602) to the left fixed base (9). Insert the zero pin (14) through the side block (1301) into the third positioning hole (30) of the protrusion (1201). At this time, the mark block (29) on the protrusion (1201) is aligned with the zero position of the positioning ruler (28) on the side block (1301), and then the entire moving base (12) is at the theoretical zero position. Zero the dial indicator (602) fixed on the fixed base (9). After the zeroing is completed, take one end of the zero pin (14) out of the third positioning hole (30). Step 4: The slider (11) moves on the slide rail (10), and the movable seat (12) fixedly connected to the slider (11) moves. The movement of the movable seat (12) causes the connecting block (16) and the support block (17) to move. Then the measuring rod (19) sleeved on the support block (17) abuts against the bracket on the guide rail I (22). The slider (11) continues to move, causing the movable seat (12) to move. Then the protrusion (1201) moves, and the detection rod of the dial indicator (602) moves with the protrusion (1201). Then the value of the dial indicator (602) is read, and the detection of the guide rail I (22) is completed. Step 5: Insert the column of the dial indicator (602) into the through hole (25) on the right support base (24), rotate the set screw (26) to fix the dial indicator (602) on the support base (24), and then fix the dial indicator (602) to the left fixed base (9). Insert the zero pin (14) through the side block (1301) into the third positioning hole (30) of the protrusion (1201). At this time, the mark block (29) on the protrusion (1201) is aligned with the zero position of the positioning ruler (28) on the side block (1301), and then the entire moving base (12) is at the theoretical zero position. The dial indicator (602) fixed on the fixed base (9) is zeroed. After the zeroing is completed, take one end of the zero pin (14) out of the third positioning hole (30). Step 6: The slider (11) moves on the slide rail (10), and the movable seat (12) fixedly connected to the slider (11) moves. The movement of the movable seat (12) causes the connecting block (16) and the support block (17) to move. Then the measuring rod (19) sleeved on the support block (17) abuts against the bracket on the guide rail II (23). The slider (11) continues to move, causing the movable seat (12) to move. Then the protrusion (1201) moves, and the detection rod of the dial indicator (602) moves with the protrusion (1201). Then the measurement value appears on the dial indicator (602), completing the detection of the guide rail II (23). Step 7: Subtract the measured values ​​from Step 4 and Step 6 to obtain the value M. If the absolute value of M is equal to 2mm, the height of the dual-track window regulator assembly meets the requirements; if the absolute value of M is not equal to 2mm, the height of the dual-track window regulator assembly does not meet the requirements. Step 8: After completing the test, remove the dial indicator (602) from the left and right mounting bases (9), and place the dial indicator (602) on the calibration pin (601) to zero it; Step 9: Pass the probe of the dial indicator (602) after it has been zeroed in step 8 through the first Y guide hole (205), the X guide hole (206), the second Y guide hole (305) and the Z guide hole (306) respectively, and make contact with the surfaces of guide rail I (22) and guide rail II (23). Read the value after the test to complete the surface contour test of the dual-track glass lifter assembly. Step 10: Rotate the first grip (404) to make the first rotating rod (403) rotate, thereby causing the first connecting bolt (405) and the first pressure block (406) at the top of the first rotating rod (403) to move, and the first pressure block (406) to not contact the guide rail I (22) and the guide rail II (23); rotate the second grip (504) to make the second rotating rod (503) rotate, thereby causing the card seat (505) at the top of the second rotating rod (503) to move, and then the card seat (505) to separate from the square pin on the guide rail I (22); remove the entire double-track glass lifter assembly from the base plate (1).
