A device for detecting the arc of a window regulator guide rail

Abstract

The present invention relates to the technical field of radian detection, and discloses a radian detection device for a glass lifter guide rail, including a workbench detection component, an error trigger component, and a locking component. During the reciprocating swing of the flip arm of the present invention, the connecting rod at the top drives the sliding sleeve and the detection roller to continuously detect the arc surface of the to-be-detected guide rail. Once the arc surface of the to-be-detected guide rail does not meet the requirements, on the one hand, the device can give feedback in time, and the operator can stop the current detection in time without completely detecting the to-be-detected guide rail, and directly replace the next workpiece for detection, further improving the overall detection efficiency; on the other hand, the detection roller will move towards the to-be-detected guide rail. Since the original movement mark of the detection roller on the guide rail is a straight line, the mark at this position will become thicker, which can visually mark the defect position point by point, enabling the operator to quickly know the location of the defect without complex data backtracking and analysis, improving the detection efficiency.

Description

Technical Field

[0001] The invention belongs to the technical field of curvature detection, and in particular relates to a curvature detection device for a glass lifter guide rail. Background Art

[0002] Window lifters play a key role in automotive parts. The curvature accuracy of their guide rails is directly related to the smoothness and stability of the glass lifting and lowering, as well as the sealing of the entire window system. The precise curvature of the guide rails can ensure the smooth movement of the glass during the lifting process, reduce noise and jamming, and enhance the waterproof, dustproof and soundproof effects of the windows. Therefore, in the production process of window lifters, accurate detection of the curvature of the guide rails is an important part of ensuring product quality.

[0003] At present, although there are many types of detection equipment for the curvature of glass lift rails on the market, there are still significant deficiencies in practical applications. Most of the existing curvature detection equipment adopts a more traditional detection mode. During the detection process, the equipment collects all-round curvature data of the rail. After the entire detection process is completed, the operator needs to use software to view the test results. This way of checking the results afterwards has a significant time lag, which makes it impossible for operators to obtain relevant information in time during the detection process, greatly reducing the detection efficiency. More importantly, when the test results show that there is a curvature defect in the rail, the operator needs to deduce the exact location of the rail defect from the coordinate points marked in the software, and the operation process is complicated.

[0049] like Figures 1 to 12 As shown, further, the clamping assembly includes a connecting seat 12, mounting plates 121 are installed on both sides of the connecting seat 12, the mounting plates 121 are fitted on the surface of the workbench 1, and the two are screwed together by bolts, the lower surface of the guide rail 14 to be measured is overlapped on the connecting seat 12, an L-shaped baffle 122 is installed on the connecting seat 12, and reinforcing ribs 123 are installed at the corners of the L-shaped baffle 122, the reinforcing ribs 123 are triangular, and one end of the guide rail 14 to be measured is fitted on the L-shaped baffle 122. A positioning seat 133 is installed on the connecting seat 12, and a screw rod 134 is rotatably installed on the positioning seat 133. A knob 135 is installed at one end of the screw rod 134, and a screw rod sleeve 131 is meshingly installed at the other end of the screw rod 134. A clamping plate 13 is installed at the end of the screw rod sleeve 131, and a pair of limiting guide rails 132 are vertically slidably installed at the bottom of the clamping plate 13. The pair of limiting guide rails 132 are installed on the connecting seat 12, and the side wall of the clamping plate 13 is in contact with the other end of the L-shaped baffle 122. Place the guide rail 14 to be measured between the L-shaped baffle 122 and the clamping plate 13, and then turn the knob 135 to drive the screw rod 134 to rotate on the positioning seat 133, and then the screw rod sleeve 131 on the screw rod 134 slides synchronously, and the screw rod sleeve 131 drives the clamping plate 13 to slide along the limiting guide rail 132 to the side of the guide rail 14 to be measured, and finally, through the cooperation of the clamping plate 13 and the L-shaped baffle 122, the guide rail 14 to be measured can be fixed as a whole.

[0050] like Figures 1 to 12 As shown, further, the rotation center of the flip arm 2 and the curvature center of the bend of the guide rail 14 to be measured are the same point, and the above requirements can be met by adjusting the clamping position of the clamping assembly and the height of the connecting seat 12 in the later stage.

[0051] Embodiment 2:

[0052] The difference between Example 1 and this Example is that: Figures 1 to 12As shown, a pointer 31 is installed at the bottom of the limit block 3, and the pointer 31 is adapted to the scale line 311 engraved on the side wall of the flip arm 2. A slide plate 32 is installed on the side wall of the limit block 3. A guide rod 322 is movably installed on the slide plate 32, and a locking bolt 321 for locking the relative position of the slide plate 32 and the guide rod 322 is installed on the slide plate 32. The locking bolt 321 penetrates the slide plate 32, and guide seats 323 are installed at both ends of the guide rod 322. The guide seat 323 is installed on the flip arm 2. The limit block 3 can be slid so that the slide plates 32 on the side walls of the two limit blocks 3 slide on the guide rod 322, and the position of the slide plates 32 is locked by the locking bolt 321. At this time, the distance between the two limit blocks 3 is within the error range, wherein the pointer 31 on the side wall of the limit block 3 can point to the corresponding scale line 311, and finally the limit block 3 can be adjusted more accurately.

[0053] like Figures 1 to 12 As shown, in a specific embodiment, a synchronous shaft 21 is fixedly installed through the bottom of the flip arm 2, the synchronous shaft 21 movably passes through the workbench 1, and one end of the synchronous shaft 21 is rotatably connected to the fixed gear 433, and the other end of the synchronous shaft 21 is installed with a crank 211, and a handle 212 is installed on the crank 211, and an anti-slip cover is installed on the surface of the handle 212. The operator rotates the handle 212, and the crank 211 is driven to rotate by the handle 212, and the crank 211 drives the synchronous shaft 21 to rotate, and the synchronous shaft 21 can finally drive the flip arm 2 to swing back and forth.

[0054] like Figures 1 to 12 As shown, further, a guide shaft 221 is installed on the top of the connecting rod 22, and the guide shaft 221 is slidably connected to the sliding sleeve 222. A synchronization block 23 is installed at the bottom of the connecting rod 22, and the synchronization block 23 is slidably installed in the inner cavity of the flip arm 2. A compression spring 231 is sleeved on the connecting rod 22 located in the inner cavity of the flip arm 2, and one end of the compression spring 231 is clamped in the inner cavity of the flip arm 2, and the other end is clamped on the synchronization block 23. The compression spring 231 ensures that the connecting rod 22 always has a downward pressing effect.

[0055] like Figures 1 to 12As shown, further, a push rod 24 is installed in the synchronization block 23, and a piston 241 is installed on the push rod 24. The piston 241 is slidably set in the inner cavity of the synchronization block 23. A return spring 245 is sleeved on the push rod 24. One end of the return spring 245 is clamped on the piston 241, and the other end of the return spring 245 is clamped in the inner cavity of the synchronization block 23. A push rod 242 is installed at the end of the push rod 24. A synchronization plate 244 is installed on the push rod 242. The end of the synchronization plate 244 is connected to the sliding sleeve 222. A side rod 243 is installed on the side wall of the push rod 242. The side rod 243 is clamped with the locking assembly. When the push rod 24 moves to the bottom of the adjusted limit block 3, the push rod 24 is squeezed to slide inside the synchronization block 23. The push rod 24 drives the piston 241 to slide in the inner cavity and compresses the return spring 245. The return spring 245 is convenient for the later reset operation. After the push rod 24 slides, the push rod 244 drives the push rod 242 and the synchronous plate 244 of the side wall to slide. At this time, the synchronous plate 244 drives the sliding sleeve 222 to move, and the sliding sleeve 222 drives the detection roller 223 to move toward the end surface of the guide rail 14 to be tested.

[0056] Embodiment 3:

[0057] The difference between Example 2 and this example is that: Figures 1 to 12As shown, the locking assembly also includes a force storage rod 4, on which a clamping block 41 is installed, one end of the clamping block 41 is chamfered, and the clamping block 41 is placed above the side rod 243, and a synchronous frame 42 is connected to the bottom of the force storage rod 4, and a limiting seat 422 is slidably installed on the force storage rod 4, and the limiting seat 422 is installed on the flip arm 2, and a force storage spring 421 is clamped between the limiting seat 422 and the synchronous frame 42, and the force storage spring 421 is installed on the outside of the force storage rod 4. A vertical plate 43 is installed on the side wall of the synchronous frame 42, and a positioning rack 431 is installed on the vertical plate 43, and a mounting frame 432 is installed at the bottom of the workbench 1, a fixed gear 433 is fixedly installed on the mounting frame 432, and the fixed gear 433 and the positioning rack 431 are adapted, a knocking rod 44 is installed on the top of the vertical plate 43, and a hammer head 441 is installed on the knocking rod 44, and the bottom of the hammer head 441 corresponds to the sound board 442 installed on the mounting frame 432, and positioning blocks 443 are installed at both ends of the sound board 442, and the positioning blocks 443 are welded to the mounting frame 432. After the push rod 242 slides outward, the side rod 243 of the side wall of the push rod 242 slides outward synchronously at this time, and the side rod 243 is separated from the block 41 on the force storage rod 4 in the locking assembly, and then under the action of the force storage spring 421, the force storage spring 421 drives the synchronous frame 42 to move downward, and then the synchronous frame 42 drives the force storage rod 4 to move downward as a whole, and the vertical plate 43 on the synchronous frame 42 drives the positioning rack 431 to be clamped on the fixed gear 433, and then the flip arm 2 is locked as a whole at this time, so when the guide rail 14 to be tested is unqualified, the movement is stopped in time to replace the next workpiece, and the guide rail 14 to be tested does not need to be fully tested, thereby improving the detection efficiency, and when the synchronous frame 42 moves downward, the knocking rod 44 on the synchronous frame 42 drives the hammer head 441 to move to the sound board 442, and the alarm operation is completed by squeezing and knocking.

[0058] The implementation principle of the device for detecting the curvature of the guide rail of a glass lifter of the present invention is as follows:

[0059] When the operator detects the curvature, he first installs the guide rail 14 to be tested on the clamping assembly. The specific steps are as follows: place the guide rail 14 to be tested between the L-shaped baffle 122 and the clamping plate 13, and then turn the knob 135 to drive the screw rod 134 to rotate on the positioning seat 133, and then the screw rod sleeve 131 on the screw rod 134 slides synchronously, and the screw rod sleeve 131 drives the clamping plate 13 to slide along the limiting guide rail 132 to the side of the guide rail 14 to be tested, and finally, through the cooperation of the clamping plate 13 and the L-shaped baffle 122, the guide rail 14 to be tested can be fixed as a whole.

[0060] When the guide rail 14 to be tested is installed on the clamping assembly, the operator can slide the limit block 3 so that the slide plates 32 on the side walls of the two limit blocks 3 slide on the guide rod 322, and lock the position of the slide plates 32 by the locking bolt 321. At this time, the distance between the two limit blocks 3 is within the error range, and the pointer 31 on the side wall of the limit block 3 can point to the corresponding scale line 311, which ultimately makes the limit block 3 more accurately adjusted.

[0061] Then the operator needs to swing the flip arm 2 back and forth. The specific operation is: the operator turns the handle 212, and the handle 212 drives the crank 211 to rotate, and the crank 211 drives the synchronous shaft 21 to rotate, and the synchronous shaft 21 can eventually drive the flip arm 2 to swing back and forth. During the reciprocating swing of the flip arm 2, the connecting rod 22 on the top of the flip arm 2 drives the sliding sleeve 222 and the detection roller 223 to detect the curved surface of the guide rail 14 to be tested. When the curved surface of the guide rail 14 to be tested meets the requirements, the error trigger component will not be triggered, thereby reminding the operator that the curvature of the guide rail 14 to be tested meets the requirements. However, when the curved surface of the guide rail 14 to be tested triggers the error trigger component due to potholes and grooves, the operator is reminded that the curvature of the guide rail 14 to be tested does not meet the requirements.

[0062] When the curvature of the guide rail 14 to be tested does not meet the requirements, that is, there are grooves and protrusions on the guide rail 14 to be tested, the detection roller 223 and the sliding sleeve 222 will slide inward or outward, thereby driving the connected connecting rod 22 to drive the synchronous block 23 to slide synchronously. When the depth of the grooves and the protrusions is too deep, the push rod 24 on the synchronous block 23 will move to the bottom of the adjusted limit block 3, and then the push rod 24 will be squeezed to slide inside the synchronous block 23. The push rod 24 drives the piston 241 to slide in the inner cavity and compresses the reset spring 245, so that the reset operation is convenient for the later stage through the reset spring 245.

[0063] After the push rod 24 slides, the push rod 242 and the synchronous plate 244 of the side wall slide. At this time, the synchronous plate 244 drives the sliding sleeve 222 to move, and the sliding sleeve 222 drives the detection roller 223 to move toward the guide rail 14 to be measured. The detection roller 223, which was originally covered with paint, slides on a plane of the guide rail 14 to be measured, so the motion mark is a straight line. However, when the detection roller 223 slides toward the end face of the guide rail 14 to be measured, the mark at this position will become thicker, which serves the purpose of fixed-point marking.

[0064] After the push rod 242 slides outward, the side rod 243 of the side wall of the push rod 242 slides outward synchronously at this time, and the side rod 243 is separated from the block 41 on the force storage rod 4 in the locking assembly, and then under the action of the force storage spring 421, the force storage spring 421 drives the synchronous frame 42 to move downward, and then the synchronous frame 42 drives the force storage rod 4 to move downward as a whole, and the vertical plate 43 on the synchronous frame 42 drives the positioning rack 431 to be clamped on the fixed gear 433, and then the flip arm 2 is locked as a whole at this time, so when the guide rail 14 to be tested is unqualified, the movement is stopped in time to replace the next workpiece, and the guide rail 14 to be tested does not need to be fully tested, thereby improving the detection efficiency, and when the synchronous frame 42 moves downward, the knocking rod 44 on the synchronous frame 42 drives the hammer head 441 to move to the sound board 442, and through squeezing and knocking, the alarm operation is completed, reminding the operator that the measured curvature of the guide rail 14 to be tested does not meet the requirements.
