Description

Technical Field

[0001] The present invention relates to the technical field of automotive window glass lifters, and particularly to a rapid clamping and testing device for automotive window glass lifters. Background Art

[0002] At present, the lifting methods of automotive glass include electric glass lifters and ordinary manual glass lifters. The principle of the electric glass lifter is to control the forward and reverse rotation of the internal motor to drive the rope, thereby driving the slider fixing the glass to slide up and down, so as to realize the opening and closing of the glass.

[0003] During the production process of window lifters, each lifter needs to be detected. However, the general detection method is manual detection, which has low work efficiency, consumes a large amount of human resources, and has poor detection accuracy, affecting product quality. The key is that there are many types of electric glass lifters, and a testing device cannot be quickly adjusted to match different sizes of electric glass lifters. Especially when some electric glass lifters have four installation points, the existing traditional three-point installation electric glass lifter testing devices cannot be used (such as CN214309454U and CN218211934U). Moreover, the clamping of the testing devices in the prior art requires manual operation, which not only cannot adapt to different types of lifters, but also the installation is often not firm and in place. Therefore, a testing device that can adapt to various size types of electric glass lifters and can be quickly clamped is needed to meet the current large-scale testing requirements of electric glass lifters. Summary of the Invention

[0004] The present invention provides a rapid clamping and testing device for automotive window glass lifters, which can solve the technical problem that the existing lifter testing devices cannot adapt to different types of electric glass lifters.

[0008] Preferably, a limit locking clamp sleeve connected to the moving bracket is sleeved on the guiding cross bar. A notch is formed on one side of the limit locking clamp sleeve, and a clamping screw is installed at the notch. The limit locking clamp sleeve can quickly limit the moving bracket to prevent it from moving during the test.

[0009] Preferably, an optoelectronic position detection component for detecting the position of the lifter is installed at the upper end of the clamping assembly. The optoelectronic position detection component includes an optoelectronic detection head and a multi-section movable bracket for fixing the optoelectronic detection head.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] AsFigures 1-10 As shown in the figure, the present invention provides a quick clamping and testing device for an automotive window regulator, which includes a machine table 1. A testing frame 2 is provided on the upper side of the machine table 1. A middle column 13 is vertically arranged in the middle of the rear side of the testing frame 2. The movable clamping unit 3 is provided in four parts, respectively installed on the upper and lower parts on both sides of the middle column 13. The movable clamping unit 3 includes an electric translation driving component, an electric lifting driving component that translates along the electric translation driving component, and a clamping component 6 that is installed on the electric lifting driving component to perform lifting. The clamping component 6 includes a clamping panel 61 and clamping cylinders 65 arranged side by side on the rear side of the clamping panel 61. A first chute 611 is horizontally arranged on the clamping panel 61. The clamping cylinder 65 drives the translation connecting plate 62 connected to it to translate. A clamping jaw 66 that translates through the first chute 611 is installed on the upper side of the translation connecting plate 62. At least one positioning block 67 is movably arranged in the first chute 611. A connecting rod 68 perpendicular to the clamping panel 61 is connected to the rear side of the clamping panel 61. A ball head 69 is arranged at the end of the connecting rod 68. A ball head sleeve 63 is sleeved outside the ball head 69. A locking nut 8 is installed at the end of the ball head sleeve 63. A lead screw adjusting seat 64 is arranged on one side of the ball head sleeve 63. The ball head sleeve 63 is connected to a lead screw nut 11 sleeved on a lead screw 9 of the lead screw adjusting seat 64. A manual adjusting knob 10 is installed at one end of the lead screw 9. By providing four movable clamping units 3, it can adapt to the installation and detection of window regulators with different sizes and different similarities. Moreover, the four movable clamping units 3 respectively form the four quadrants of a plane coordinate system, so that no matter the installation position and orientation of the window regulator in the car door can be simulated, which is very convenient. In addition, the clamping component 6 adopts an automatic clamping structure and has multiple adjustment joints, which is very flexible to adjust.

[0028] Specifically, a suitable movable clamping unit 3 is selected to fix the window lifter according to the installation position and installation points of the automotive window lifter to be tested. The position of the clamping component 6 on each movable clamping unit 3 can be quickly adjusted by the electric translation drive component and the electric lifting drive component. After the clamping component 6 is adjusted to the corresponding position, the mounting feet on the window lifter can be positioned by the positioning block 67. Then, two clamping cylinders 65 drive two clamping jaws 66 to clamp the mounting feet simultaneously, so that the mounting feet will not move. Then, the position of the clamping panel 61 can also be adjusted by the ball head 69 at the end of the connecting rod 68, so as to realize the quick and firm installation of the window lifter. Among them, a positioning insertion post 613 is provided at the front end of the positioning block 67. Through the positioning insertion post 613, the mounting holes on the mounting feet of the window lifter can be quickly positioned, which is convenient for the clamping jaws 66 to clamp and fix the mounting feet on the window lifter. The position of the positioning block 67 can be located between the two clamping jaws 66 or on the outer side of the clamping jaws 66, and the quantity changes according to the shape of the mounting feet.

[0029] The manual adjustment knob 10 on the lead screw adjustment seat 64 can also be rotated to adjust the position of the lead screw nut 11, so as to realize the front and back adjustment of the connecting rod 68. Combined with the rotation of the ball head 69, a large-range adjustment of the position of the clamping panel 61 can be realized.

[0030] As Figure 10 shown, during the test, glass can be installed on the lifting slider of the window lifter to simulate the actual vehicle loading state. It can be used as a durability test device or as a vehicle loading adaptation test.

[0031] In this embodiment, as Figures 3-5 shown, the electric translation drive component includes a guiding cross bar 31 arranged in parallel up and down and a translation lead screw 34 arranged horizontally. The translation lead screw 34 and the guiding cross bar 31 are both connected to the test frame 2 and the middle column 13. The guiding cross bar 31 and the translation lead screw 34 both pass through the vertically arranged moving bracket 33. One end of the translation lead screw 34 is equipped with a translation motor 35 for driving the translation lead screw 34 to rotate. The electric lifting drive component is installed on the moving bracket 33. By controlling the rotation of the translation lead screw 34 by the translation motor 35, the horizontal displacement of the electric lifting drive component can be accurately controlled, and it can be controlled on both the left and right sides. The guiding cross bars 31 on the left and right movable clamping units 3 can be shared to improve the firmness, and the moving bracket 33 can move smoothly along the guiding cross bar 31.

[0032] In this embodiment, as Figures 3-5As shown in the figure, the electric lifting drive assembly includes cross beams 36 installed at the upper and lower ends of the moving bracket 33 and extending forward. A lifting lead screw 39 is vertically installed in the middle between the cross beams 36. A lifting lead screw nut 37 is installed on the lifting lead screw 39. The clamping assembly 6 is installed on the lifting lead screw nut 37. An electric lifting motor 38 is installed at the end of the lifting lead screw nut 37. The precise up and down displacement of the clamping assembly 6 can be controlled by the electric lifting motor 38, which can meet the needs of lifters with different types and installation positions. Lifting guide rods with both ends connected to the cross beams 36 can be arranged on both sides of the lifting lead screw 39. The lifting guide rods all pass through the lifting lead screw nut 37, which can prevent the lifting lead screw nut 37 from rotating.

[0033] At the same time, as Figures 3-5 shown, a limit locking clamp sleeve 32 connected to the moving bracket 33 is sleeved on the guiding cross bar 31. A notch is opened on one side of the limit locking clamp sleeve 32, and a clamping screw is installed at the notch. The limit locking clamp sleeve 32 can quickly limit the moving bracket 33 to prevent it from moving during the test. When the moving bracket 33 is driven by the lead screw to the specified position, the clamping screw on the limit locking clamp sleeve 32 can be rotated to clamp the guiding cross bar 31.

[0034] In this embodiment, a photoelectric position detection assembly 7 for detecting the position of the lifter is installed at the upper end of the clamping assembly 6. The photoelectric position detection assembly 7 includes a photoelectric detection head 71 and a multi-joint movable bracket 73 for fixing the photoelectric detection head 71. A magnet 72 is installed at the bottom of the multi-joint movable bracket 73. The magnet 72 is adsorbed on the upper end of the clamping panel 61. The photoelectric position detection assembly 7 can detect the position of the installation point of the lifter during the test, detect the displacement and whether it is installed in place. The photoelectric position detection assembly 7 can be quickly and flexibly adjusted in position through the multi-joint movable bracket 73 and the magnet 72. The rotation joint positions of the multi-joint movable bracket 73 can all be connected by a rotating shaft or a ball head, and the rotation has a damping effect and can maintain the position at any time. Multiple photoelectric detection heads 71 can be connected to an integrated tube 12 at the rear side of the test device through signal lines, so that the signal lines will not be messy and will not affect the operation of the movable clamping unit 3.

[0035] In this embodiment, as Figure 7 shown, a second chute 612 parallel to the first chute 611 is provided at the lower part of the clamping panel 61. The clamping cylinder 65 is adjustably installed in the second chute 612 through a fastener. The clamping cylinder 65 can be adjusted in position through the second chute 612 to adapt to lifters of different sizes and models.

[0036] In this embodiment, in order to better control each clamping assembly 6, asFigure 1 As shown, on the upper front surface of the machine table 1, there are direction control buttons 4 for controlling the corresponding clamping components 6 to move in the left, right, up, and down directions. On the front end surface of the machine table 1, there are also power switches 14 corresponding to each clamping component 6. After the power switch 14 turns on the power of the corresponding clamping component 6, the direction control button 4 controls the corresponding clamping component 6 to operate. By switching the power switch 14, the power of a certain clamping component 6 can be turned on, so that the direction control button 4 can be used to uniformly adjust the energized clamping component 6, which is very convenient to operate. On one side of the power switch 14, a display module 5 can be installed, which can display the test parameters, such as the number of times the lifter operates, and so on.

[0037] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0038] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0039] In the present invention, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the technical solutions between various embodiments of the present invention can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
