Description

Technical Field

[0001] The present invention relates to the technical field of part detection, and particularly to a rigidity detection device for automobile part production. Background Art

[0002] Automobile parts are each unit that constitutes an automobile as a whole and a product serving the automobile. There is a wide variety of automobile accessories. With the improvement of people's living standards, people's consumption of automobiles is increasing, and the market for automobile accessories is also becoming larger and larger. When automobile parts are produced, after the parts are produced, they need to be detected. Among them, the rigidity detection of parts is one of the important detections. When performing rigidity detection, the three-point support method is one of the commonly used methods. The three-point support method mainly restricts the movement direction of the part by using two support points, and then performs mechanical measurement through another force point to obtain relevant parameters such as the bending stiffness of the part. When performing the rigidity detection of automobile parts, the operation of the three-point support method is mostly to place the part on a frame that supports both sides of the part, and then apply pressure at the middle position of the upper end for detection. However, the shapes of automobile parts are diverse, and the lower ends of different types of shapes are not in a flat state, and there are often special-shaped structures. When performing support, the support effect is poor, and the part is prone to tilt, resulting in deviation of the detection result and inconvenience in use. When the current detection equipment is in use, when supporting the lower end of a special-shaped mechanism, it often needs to be adjusted multiple times and different pads are used for support, the operation is relatively troublesome, and the detection efficiency is low. Summary of the Invention

[0003] To overcome the technical defects existing in the prior art, the present invention provides a rigidity detection device for automobile part production, which is convenient for performing rigidity detection on special-shaped automobile parts, improves the support effect on both sides of the lower end of the part, and is convenient for operation during support, and has the effect of improving the detection efficiency.

[0004] The technical solution adopted by the present invention is as follows: A rigidity detection device for automobile part production, including a main body assembly. The main body assembly includes a detection table. Support mechanisms are symmetrically installed inside the detection table. The upper ends of the support mechanisms extend above the detection table. A control host is fixedly installed on one side of the exterior of the detection table. A gantry is fixedly installed at the upper end of the detection table. A cylinder is fixedly installed at the middle position of the upper end of the gantry. And the telescopic end of the cylinder is fixedly installed with a detection head. Threaded columns are threadedly connected to both sides of the cylinder on the gantry. And the lower ends of the threaded columns are rotatably installed with upper pressing plates. The support mechanism includes a frame body assembly. A driving component is installed at the lower end of the frame body assembly. And supporting components are arrayed on the frame body assembly. And a limiting component for limiting the supporting components is installed on one side of the frame body assembly. An automobile part is clamped between the supporting components and the upper pressing plate. When in use, an automobile part to be detected is placed at the middle position of the upper surface of the detection table. And by turning the threaded columns, the upper pressing plates are lowered, so that the workpiece to be measured is pre-fixed on the detection table. Then the position of the support mechanism is adjusted, so that the support mechanism moves to both sides of the lower end of the workpiece to be measured. After determining the position of the support mechanism, the support mechanism is fixed on the detection table. Then the driving component is turned on, so that the driving component drives the supporting components, so that the supporting components move upward to support both sides of the lower end of the workpiece to be measured. The supporting components support the workpiece to be measured. And after the support, the limiting component limits the supporting components to improve the support effect on the workpiece to be measured. Then the cylinder is turned on, so that the detection head applies pressure to the workpiece to be measured. The detection head displays the detection information on the control host to judge the rigidity of the workpiece to be measured.

[0005] Preferably, through holes are symmetrically arrayed in the left-right direction at the upper end of the detection table. The upper ends of the supporting components penetrate through the through holes and extend to the upper end of the detection table. And waist-shaped holes are symmetrically opened in the front-back direction at the upper end of the detection table. Both ends of the frame body assembly penetrate through the waist-shaped holes and extend to the upper end of the detection table. First internal threaded tubes are fixedly installed at both ends of the cylinder on the gantry. The threaded columns are threadedly connected to the first internal threaded tubes. And the lower end of the detection table is of a hollow structure. When fixing the support mechanism, the frame body assembly in the support mechanism is fixed inside the waist-shaped holes. When the support mechanism supports the workpiece to be measured, the upper ends of the supporting components extend above the detection table through the through holes to support the workpiece to be measured. And through the first internal threaded tubes, when pre-fixing the upper part of the workpiece to be measured through the upper pressing plates, the threaded columns move up and down along the first internal threaded tubes to achieve the effect of adjusting the position of the upper pressing plates.

[0006] Preferably, sliding rails are fixedly installed at both the upper and lower ends inside the inspection table, which are symmetrically arranged front and back. Both the front and back sides of the support mechanism are slidably clamped on the sliding rails. Inside the inspection table, electric sliding rails are symmetrically installed left and right between the vertically distributed sliding rails, and the moving end of the electric sliding rail is fixedly connected to the support mechanism. Through the sliding rails, the bearing capacity of the support mechanism is improved. Through the electric sliding rails, it is convenient to adjust the left and right positions of the support mechanism, facilitating the support of different types of test pieces and improving applicability.

[0007] Preferably, the frame assembly includes a frame. Sliders are fixedly installed at both the upper and lower ends on both sides of the frame, and the sliders are slidably clamped inside the inspection table. Inner threaded blind tubes are fixedly installed at both upper sides of the frame, and limit nuts are threadedly connected to the inner threaded blind tubes, and one side of the limit nut is pressed against the upper surface of the inspection table. A cross bar is fixedly installed at one lower side of the frame, and guide holes are symmetrically formed front and back on the cross bar. The limit assembly is installed on one side of the cross bar, and one end of the limit assembly is inserted into the guide hole. When adjusting the position of the support mechanism, the electric sliding rail drives the frame to move left and right, and the frame moves on the sliding rail through the sliders, facilitating the adjustment of the support position. After the adjustment is completed, by screwing the limit nut, one end of the limit nut is pressed against the upper surface of the inspection table, thereby restricting the movement of the frame. Through the cross bar and the guide holes, after the support is completed, the limit assembly moves on the cross bar to limit the lifting assembly, achieving the effect of stable support.

[0008] Preferably, lower bearings are installed in an array along the front-back direction at the lower end of the frame. One end of the driving component is fixedly installed on the inner ring of the lower bearing. A partition is fixedly installed at the lower end inside the frame, and an upper bearing is fixedly installed on the partition directly above the lower bearing. The lower end of the lifting component is fixedly installed on the inner ring of the upper bearing. A second inner threaded tube is fixedly installed directly above the upper bearing at the upper end of the frame, and the upper end of the lifting component is threadedly connected to the second inner threaded tube. Through the lower bearing, when the driving component is turned on, the upper end of the driving component rotates inside the lower bearing, and the lower end of the lifting component rotates on the upper bearing, achieving the effect of the driving component driving the lifting component. When the lifting component rotates, the upper end of the lifting component rises and falls on the second inner threaded tube to support the test piece.

[0009] Preferably, the driving assembly includes a driving motor and a lower rotating shaft. The lower rotating shaft is fixedly installed on the inner ring of the lower bearing, and a driven sprocket is fixedly installed at the lower end of the lower rotating shaft. The driving motor is fixedly installed on one side of the frame, and a driving sprocket is fixedly installed at the output end of the driving motor. A chain is sleeved between the driven sprocket and the driving sprocket. The upper end of the lower rotating shaft is fixedly installed with a lower turntable, and first magnet blocks are fixedly installed on the lower turntable in a circumferential array. When the driving motor is started, the driving sprocket drives the driven sprocket to rotate through the chain, the lower rotating shaft drives the lower turntable to rotate, and the lower turntable and the upper turntable in the lifting assembly are magnetically connected through the first magnet blocks to form the effect of a flexible shaft connection, so that the lower turntable drives the upper turntable.

[0010] Preferably, the lifting assembly includes an upper rotating shaft. The upper rotating shaft is fixedly installed on the inner ring of the upper bearing, and an upper turntable is fixedly installed at the lower end of the upper rotating shaft. Second magnet blocks are installed in a circumferential array at the lower end of the upper turntable. A plum blossom-shaped linkage rod is fixedly installed at the upper end of the upper rotating shaft. A sleeve pipe is sleeved on the linkage rod. A lead screw is fixedly installed at the upper end of the sleeve pipe, and the lead screw is in threaded connection with the second internal threaded pipe. The upper end of the lead screw is rotatably installed with a lower pressing plate. The upper turntable is rotatably installed on the upper bearing through the upper rotating shaft. And through the second magnet blocks on the upper turntable, when the lower turntable rotates, due to the magnetic adsorption between the first magnet blocks and the second magnet blocks, the lower turntable drives the upper turntable to rotate, so that the linkage rod rotates. The linkage rod drives the sleeve pipe and the lead screw to rotate, and the lead screw rises and falls on the second internal threaded pipe to achieve the effect of adjusting the position of the lower pressing plate. The lifting assemblies are in multiple groups. When the lower pressing plate in one of the lifting assemblies is in contact with the workpiece to be measured, the rotation of the upper turntable is restricted. Since the lower turntable and the upper turntable are magnetically soft-connected, when one of the upper turntables does not rotate, the corresponding lower turntable rotates self-adaptively, so that the rising heights of different lifting assemblies are different, which is convenient for supporting special-shaped parts.

[0011] Preferably, a blind hole matching the linkage rod is opened at the lower end of the sleeve pipe, and a universal ball seat is fixedly installed at the upper end of the lead screw. The lower end of the lower pressing plate is fixedly installed at the upper end of the universal ball seat. When the lower pressing plate rises and falls, the sleeve pipe rises and falls on the linkage rod, and through the universal ball seat, when the lower pressing plate supports the workpiece to be measured, the inclination angle of the lower pressing plate is self-adaptive.

[0012] Preferably, the limiting component includes a limiting strip. A limiting groove is formed on one side of the limiting strip, and an electric telescopic rod is fixedly installed at the middle position on one side of the limiting strip. The electric telescopic rod is fixedly installed on one side of the cross bar. Guide rods with a T-shaped structure are fixedly installed at both ends on one side of the limiting strip. The guide rods are inserted into the inside of the guide holes, facilitating guiding when the limiting strip moves. After the support is completed, by activating the electric telescopic rod, the limiting strip moves towards the linkage rod direction, and the limiting groove is clamped on the protrusion on the linkage rod, restricting the rotation of the linkage rod, and further restricting the rotation of the lead screw, improving the stability of the support.

[0013] The beneficial effects of the present invention are as follows: When carrying out support, by adjusting the distance between the support mechanisms, it is convenient to detect automobile parts of different sizes. The lower turntable is driven to rotate by the driving component. The lower turntable and the upper turntable are softly connected by the first magnet and the second magnet, so that the lower turntable drives the upper turntable to rotate. Furthermore, the lead screw moves upward along the second internal thread tube. When contacting the component, the lower turntable rotates while the upper turntable does not rotate, facilitating the adjustment of the protruding height of the lead screw at different positions, supporting both sides at the lower end of the special-shaped automobile part, improving the support effect and the support efficiency. After the support is completed, the detection head is pushed down by the air cylinder to achieve the effect of rigid detection of the automobile part, which is convenient to operate and improves the detection efficiency.

[0026] The present invention will be further described below with reference to the accompanying drawings: As Figures 1 - 11As shown in the figure, this embodiment provides a rigidity detection device for automobile part production, including a main body component 1. The main body component 1 includes a detection table 101. Support mechanisms 2 are symmetrically installed inside the detection table 101. The upper ends of the support mechanisms 2 extend above the detection table 101. A control host 3 is fixedly installed on one side of the outside of the detection table 101. A gantry 102 is fixedly installed at the upper end of the detection table 101. A cylinder 4 is fixedly installed at the middle position of the upper end of the gantry 102. And a detection head 5 is fixedly installed at the telescopic end of the cylinder 4. Threaded columns 103 are threadedly connected on both sides of the cylinder 4 on the gantry 102. And a upper pressure plate 104 is rotatably installed at the lower end of the threaded column 103. The support mechanism 2 includes a frame component 21. A driving component 22 is installed at the lower end of the frame component 21. And a lifting component 23 is installed in an array on the frame component 21. And a limiting component 24 for limiting the lifting component 23 is installed on one side of the frame component 21. The automobile part is clamped between the lifting component 23 and the upper pressure plate 104. When in use, the automobile part to be detected is placed at the middle position of the upper surface of the detection table 101. And by turning the threaded column 103, the upper pressure plate 104 is lowered, so that the part to be tested is pre-fixed on the detection table 101. Then the position of the support mechanism 2 is adjusted, so that the support mechanism 2 moves to both sides of the lower end of the part to be tested. After determining the position of the support mechanism 2, the support mechanism 2 is fixed on the detection table 101. Then the driving component 22 is started, so that the driving component 22 drives the lifting component 23, so that the lifting component 23 moves upward to support both sides of the lower end of the part to be tested. And the limitation of the upper pressure plate 104 on the part to be tested is gradually released, so that the lifting component 23 supports the part to be tested. And after the lifting, the limiting component 24 limits the lifting component 23 to prevent the lifting component 23 from descending, improving the support effect on the part to be tested, so that the part to be tested is clamped between the upper pressure plate 104 and the lifting component 23. Then the cylinder 4 is started, so that the detection head 5 applies pressure to the part to be tested. The detection head 5 displays the detection information on the control host 3 to judge the rigidity of the part to be tested. And there are multiple lifting components 23. When supporting the part to be tested, it is convenient to support the special-shaped parts to avoid deviation or movement during detection, improving the support effect.

[0027] As a technical optimization scheme of the present invention, specifically as Figure 3As shown in the figure, through holes 105 are symmetrically arranged in an array from left to right at the upper end of the detection table 101. The upper end of the support component 23 penetrates through the through holes 105 and extends to the upper end of the detection table 101. Moreover, waist-shaped holes 106 are symmetrically arranged from front to back at the upper end of the detection table 101. Both ends of the frame component 21 penetrate through the waist-shaped holes 106 and extend to the upper end of the detection table 101. First internal threaded pipes 107 are fixedly installed at both ends of the cylinder 4 on the gantry 102. The threaded column 103 is threadedly connected to the first internal threaded pipe 107. And the lower end of the detection table 101 is a hollow structure. Through the hollow structure at the lower end, it is convenient to discharge debris or parts that fall into the interior of the detection table 101 from the positions of the through holes 105 or waist-shaped holes 106. And when fixing the support mechanism 2, the frame component 21 in the support mechanism 2 is fixed inside the waist-shaped holes 106. When the support mechanism 2 supports the workpiece to be measured, the upper end of the support component 23 extends above the detection table 101 through the through holes 105 to support the workpiece to be measured. And through the first internal threaded pipe 107, when pre-fixing the upper part of the workpiece to be measured through the upper pressing plate 104, rotate the threaded column 103, and the threaded column 103 moves up and down along the first internal threaded pipe 107 to achieve the effect of adjusting the position of the upper pressing plate 104. Sliding tracks 108 are fixedly installed at the upper and lower ends that are symmetrically arranged from front to back inside the detection table 101. The front and rear sides of the support mechanism 2 are slidably clamped on the sliding tracks 108. And electric sliding rails 109 are symmetrically installed from left to right inside the detection table 101 between the sliding tracks 108 distributed up and down. And the moving end of the electric sliding rail 109 is fixedly connected to the support mechanism 2. Through the sliding tracks 108, the bearing capacity of the support mechanism 2 is improved. And through the electric sliding rails 109, it is convenient to adjust the left and right positions of the support mechanism 2, which is convenient for supporting different types of workpieces to be measured and improves the applicability during use.

[0028] As a technical optimization solution of the present invention, specifically as Figure 6 and Figure 7As shown in the figure, the frame assembly 21 includes a frame 2101. Sliders 2110 are fixedly installed at the upper and lower ends on both sides of the frame 2101. The sliders 2110 are slidably clamped inside the inspection table 101. Inner threaded blind tubes 2102 are fixedly installed at both sides of the upper end of the frame 2101. A limit nut 2103 is threadedly connected to the inner threaded blind tube 2102, and one side of the limit nut 2103 is pressed against the upper surface of the inspection table 101. A cross bar 2104 is fixedly installed at one side of the lower end of the frame 2101. Guide holes 2105 are symmetrically arranged in the front and rear directions on the cross bar 2104. The limit assembly 24 is installed on one side of the cross bar 2104, and one end of the limit assembly 24 is inserted into the guide hole 2105. When adjusting the position of the support mechanism 2, the electric slide rail 109 drives the frame 2101 to move left and right. The frame 2101 moves on the sliding track 108 through the sliders 2110, which is convenient for adjusting the support position. After the adjustment is completed, by turning the limit nut 2103, the limit nut 2103 moves into the inner threaded blind tube 2102, and one end of the limit nut 2103 is pressed against the upper surface of the inspection table 101, thereby restricting the movement of the frame 2101 and improving the stability during support. Through the cross bar 2104 and the guide holes 2105, after the support is completed, the limit assembly 24 moves on the cross bar 2104 to limit the lifting assembly 23, achieving the effect of stable support. Lower bearings 2106 are arranged in an array along the front and rear directions at the lower end of the frame 2101. One end of the drive assembly 22 is fixedly installed on the inner ring of the lower bearing 2106. A partition plate 2107 is fixedly installed at the lower end inside the frame 2101. An upper bearing 2108 is fixedly installed on the partition plate 2107 directly above the lower bearing 2106. The lower end of the lifting assembly 23 is fixedly installed on the inner ring of the upper bearing 2108. A second inner threaded tube 2109 is fixedly installed at the upper end of the frame 2101 directly above the upper bearing 2108. The upper end of the lifting assembly 23 is threadedly connected to the second inner threaded tube 2109. Through the lower bearing, when the drive assembly 22 is turned on, the upper end of the drive assembly 22 rotates inside the lower bearing 2106, and the lower end of the lifting assembly 23 rotates on the upper bearing 2108, achieving the effect of the drive assembly 22 driving the lifting assembly 23. When the lifting assembly 23 rotates, the upper end of the lifting assembly 23 moves up and down on the second inner threaded tube 2109, achieving the effect of supporting the workpiece to be measured.

[0029] As a technical optimization solution of the present invention, specifically as Figure 8 and Figure 9As shown in the figure, the driving assembly 22 includes a driving motor 2201 and a lower rotating shaft 2202. The lower rotating shaft 2202 is fixedly installed on the inner ring of the lower bearing 2106, and a driven sprocket 2203 is fixedly installed at the lower end of the lower rotating shaft 2202. The driving motor 2201 is fixedly installed on one side of the frame 2101, and a driving sprocket 2204 is fixedly installed at the output end of the driving motor 2201. A chain 2205 is sleeved between the driven sprocket 2203 and the driving sprocket 2204. An upper turntable 2206 is fixedly installed at the upper end of the lower rotating shaft 2202. First magnet blocks 2207 are fixedly installed on the upper turntable 2206 in a circumferential array. When the driving motor 2201 is turned on, the driving motor 2201 drives the driving sprocket 2204 to rotate, and through the chain 2205, the driving sprocket 2204 drives the driven sprocket 2203 to rotate, so that the lower rotating shaft 2202 drives the upper turntable 2206 to rotate. The upper turntable 2206 in the lifting assembly 23 is magnetically connected through the first magnet blocks 2207 to form the effect of a flexible shaft connection, so that the upper turntable 2206 drives the upper turntable 2302.

[0030] As a technical optimization solution of the present invention, specifically as Figure 10As shown in the figure, the lifting component 23 includes an upper rotating shaft 2301, which is fixedly installed on the inner ring of the upper bearing 2108. The lower end of the upper rotating shaft 2301 is fixedly installed with an upper turntable 2302, and the lower end of the upper turntable 2302 is circumferentially and arrayedly installed with second magnet blocks 2303. The upper end of the upper rotating shaft 2301 is fixedly installed with a plum-blossom-shaped linkage rod 2304. A sleeve pipe 2305 is sleeved on the linkage rod 2304. The upper end of the sleeve pipe 2305 is fixedly installed with a lead screw 2306, and the lead screw 2306 is threadedly connected with the second internal thread pipe 2109. The upper end of the lead screw 2306 is rotatably installed with a lower pressing plate 2307. The upper turntable 2302 is rotatably installed on the upper bearing 2108 through the upper rotating shaft 2301. And through the second magnet blocks 2303 on the upper turntable 2302, when the lower turntable 2206 rotates, due to the magnetic adsorption between the first magnet block 2207 and the second magnet block 2303, the effect that the lower turntable 2206 drives the upper turntable 2302 to rotate is achieved, so that the linkage rod 2304 rotates. The linkage rod 2304 drives the sleeve pipe 2305 and the lead screw 2306 to rotate. The lead screw 2306 moves up and down on the second internal thread pipe 2109, achieving the effect of adjusting the position of the lower pressing plate 2307. And there are multiple groups of lifting components 23. When the lower pressing plate 2307 in one group of lifting components 23 is in contact with the component to be measured, the rotation of the upper turntable 2302 is restricted. Since the lower turntable 2206 and the upper turntable 2302 are magnetically soft-connected, when one of the upper turntables 2302 does not rotate, the corresponding lower turntable 2206 rotates self-adaptively, avoiding the phenomenon of jamming, so that the rising heights of different lifting components 23 are different, which is convenient for supporting special-shaped parts and improving the support efficiency. A blind hole 2308 that matches the linkage rod 2304 is opened at the lower end of the sleeve pipe 2305, and a universal ball seat 2309 is fixedly installed at the upper end of the lead screw 2306. The lower end of the lower pressing plate 2307 is fixedly installed on the upper end of the universal ball seat 2309. When the lower pressing plate 2307 moves up and down, the sleeve pipe 2305 moves up and down on the linkage rod 2304, not only ensuring the stability of rotation, but also ensuring the stability of the up and down movement of the lower pressing plate 2307. And through the universal ball seat 2309, when the lower pressing plate 2307 supports the component to be measured, the inclination angle of the lower pressing plate 2307 is self-adaptive.

[0031] As a technical optimization scheme of the present invention, specifically as Figure 11As shown, the limit component 24 includes a limit bar 2401. A limit groove 2402 is formed on one side of the limit bar 2401, and an electric telescopic rod 2403 is fixedly installed at the middle position on one side of the limit bar 2401. The electric telescopic rod 2403 is fixedly installed on one side of the cross bar 2104. T-shaped guide rods 2404 are fixedly installed at both ends on one side of the limit bar 2401. The guide rods 2404 are inserted into the inside of the guide holes 2105. After the support is completed, by turning on the electric telescopic rod 2403, the limit bar 2401 moves towards the linkage rod 2304, and the limit groove 2402 is clamped on the protrusion on the linkage rod 2304, restricting the rotation of the linkage rod 2304, thereby restricting the rotation of the lead screw 2306 and preventing the lower pressing plate 2307 from descending, improving the stability of the support.
