Description

Technical Field

[0001] This utility model relates to the field of stamping part inspection technology, specifically a stamping part hole position detection device. Background Technology

[0002] During automobile manufacturing, many parts are punched by stamping to facilitate assembly and fixing. However, during the punching process, the punching position may be misaligned or some parts may not be punched. These defective stamped parts are considered substandard products and are not easy to assemble. To inspect the quality of mass-produced stamped parts, a stamped part hole position detection device is used to distinguish them.

[0003] Currently, some stamping part hole position detection devices fix the stamping parts to a fixed rod when inspecting them, and then use an industrial camera fixed on a robotic arm for visual inspection. In order to accurately inspect all the stamping parts on the fixed rod, one end of the fixed rod is usually connected and fixed to the drive mechanism. This means that after the stamping parts are inspected, they need to be removed from the fixed rod one by one, or replaced in batches by removing the fixed rod. This makes the loading and unloading process of stamping parts cumbersome and time-consuming, affecting the inspection efficiency of the hole positions of stamping parts. Utility Model Content

[0004] The purpose of this invention is to provide a device for detecting the hole position of stamped parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping part hole position detection device, comprising: a base plate; a support plate fixedly disposed on the base plate; a stamping part mounting rod rotatably disposed on the support plate; a fixing plate fixedly disposed on the base plate; a connecting sleeve rotatably disposed on the fixing plate, one end of the stamping part mounting rod being inserted into the connecting sleeve; a plurality of clamping pieces fixedly disposed inside the connecting sleeve; an adjusting sleeve threadedly disposed inside the connecting sleeve, one end of the adjusting sleeve being in contact with the surface of the clamping pieces; when the adjusting sleeve is configured to rotate inward into the connecting sleeve, the clamping pieces are deformed by the pressure of the adjusting sleeve to compress and fix the stamping part mounting rod; a drive motor fixedly disposed on the fixing plate; and an angle adjustment mechanism disposed on the fixing plate, the angle adjustment mechanism being driven by the drive motor and the connecting sleeve respectively.

[0006] Preferably, the angle adjustment mechanism includes: an adjustment disk rotatably mounted on a fixed plate, the shaft end of the adjustment disk being driven by a connecting sleeve; a driven gear disk rotatably mounted on the fixed plate, the outer surface of the driven gear disk meshing with the output end of a drive motor; a plurality of actuating grooves evenly distributed on the adjustment disk 10; and a push rod fixedly mounted on the end face of the driven gear disk, wherein when the push rod rotates with the driven gear disk, the push rod slides into the actuating groove and pushes the adjustment disk to rotate.

[0007] Preferably, it further includes: a positioning disk, fixedly disposed at the axis of the driven gear disk; and a plurality of positioning grooves, evenly distributed on the surface of the adjusting disk, wherein the position of the adjusting disk is fixed when the surface of the positioning disk is configured to fit against the inner surface of the positioning groove.

[0008] Preferably, it further includes: a plurality of clearance grooves evenly distributed on the surface of the positioning disk, wherein the adjusting disk can rotate when the surface of the clearance grooves mates with the surface of the adjusting disk.

[0012] This utility model provides a device for detecting the hole position of stamped parts, which has the following advantages:

[0013] (1) By setting up a connecting sleeve, a clamping plate and an adjusting sleeve, the present invention can make the adjusting sleeve enter the interior of the connecting sleeve by rotating the adjusting sleeve. During the process of the adjusting sleeve entering, the clamping plate is pushed by the inclined surface, causing the clamping plate to bend towards the stamping part mounting rod, so that it is tightly squeezed and attached to the stamping part mounting rod, thus fixing the stamping part mounting rod. When disassembling, it is only necessary to rotate the adjusting sleeve in the opposite direction to release the clamping plate from the stamping part mounting rod, thereby realizing the rapid installation and disassembly of the stamping part mounting rod and improving the detection efficiency of punching holes in stamping parts.

[0014] (2) This utility model drives the driven toothed disc to rotate by a drive motor, so that the push rod intermittently enters the actuation groove. Under the drive of the driven toothed disc, the push rod pushes the adjustment disc to rotate and finally disengages from the actuation groove, causing the stamping part mounting rod to rotate. This facilitates the industrial camera on the robotic arm to inspect the obscured stamping parts, further improving the inspection efficiency. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: Referring to 1-4, in this embodiment, a stamping part hole position detection device includes: a base plate 1; a support plate 2, fixedly disposed on the base plate 1; a stamping part mounting rod 3, rotatably disposed on the support plate 2; a fixing plate 4, fixedly disposed on the base plate 1; a connecting sleeve 5 rotatably disposed on the fixing plate 4, with one end of the stamping part mounting rod 3 inserted into the connecting sleeve 5; a plurality of clamping pieces 6, fixedly disposed inside the connecting sleeve 5; an adjusting sleeve 7, threadedly disposed inside the connecting sleeve 5, with one end of the adjusting sleeve 7 in contact with the surface of the clamping pieces 6; when the adjusting sleeve 7 is configured to rotate inward into the connecting sleeve 5, the clamping pieces 6 are deformed by the pressure of the adjusting sleeve 7 to press and fix the stamping part mounting rod 3; a drive motor 14, fixedly disposed on the fixing plate 4; and an angle adjustment mechanism. The angle adjustment structure is mounted on the fixed plate 4 and is connected to the drive motor 14 and the connecting sleeve 5 respectively. The clamping plate 6 can be used to connect and fix the stamping part mounting rod 3 under the push of the adjusting sleeve 7. The clamping plate 6 is made of elastic material with high memory and can quickly recover after being separated from the adjusting sleeve 7. It can be made of spring steel or memory metal. When connecting and fixing the stamping part mounting rod 3, the operator puts the stamping part mounting rod 3 with the stamping part installed on it into the support plate 2, and then pushes the end with the friction texture 9 into the connecting sleeve 5. Then the operator rotates the adjusting sleeve 7 to let it enter the connecting sleeve 5. During the entry process, the clamping plate 6 is pushed against the surface of the stamping part mounting rod 3 and finally fixed by the cooperation of the inclined surface 8.

[0022] The angle adjustment mechanism includes: an adjustment disk 10, rotatably mounted on a fixed plate 4, with its shaft end connected to a connecting sleeve 5; a driven gear disk 12, rotatably mounted on the fixed plate 4, with its outer surface meshing with the output end of a drive motor 14; several actuating grooves 11 evenly spaced on the adjustment disk 10; and a push rod 13 fixedly mounted on the end face of the driven gear disk 12. The push rod 13 is configured to slide into the actuating grooves 11 and push the adjustment disk 10 to rotate when it follows the rotation of the driven gear disk 12. Driven by the driven gear 12, the push rod 13 enters the actuation groove 11 and pushes the adjustment plate 10 to rotate during the subsequent sliding process, thereby adjusting the angle of the stamping part mounting rod 3. When some stamping parts cannot be detected due to obstruction, the drive motor 14 drives the driven gear 12 to rotate, causing the push rod 13 to enter the actuation groove 11. Driven by the driven gear 12, the push rod 13 pushes the adjustment plate 10 to rotate and finally disengages from the actuation groove 11, causing the stamping part mounting rod 3 to rotate, making it easier to detect the obstructed stamping parts.

[0023] It also includes: a positioning disk 15, which is fixedly set at the axis of the driven gear disk 12; and several positioning grooves 16, which are evenly opened on the surface of the adjusting disk 10. When the surface of the positioning disk 15 is set to fit against the inner surface of the positioning groove 16, the position of the adjusting disk 10 is fixed, which can keep it stable when the industrial camera 19 takes pictures and detects, and avoid shaking.

[0024] It also includes: several clearance grooves 17, which are evenly opened on the surface of the positioning plate 15. When the surface of the clearance groove 17 is in contact with the surface of the adjustment plate 10, the adjustment plate 10 can rotate, avoiding obstruction of the adjustment plate 10 and facilitating rotation.

[0025] It also includes: a bevel 8, which is formed at the pressing end of the adjusting sleeve 7 and the clamping piece 6, and the two bevels 8 on the adjusting sleeve 7 and the clamping piece 6 are in contact with each other; and a friction texture 9, which is formed at the fixed end of the stamping part mounting rod 3 and the contact surface of the clamping piece 6. The bevel 8 makes it easier for the adjusting sleeve 7 to push the clamping piece 6, and the friction texture 9 increases the friction between the stamping part mounting rod 3 and the clamping piece 6, making them more firmly fixed.

[0026] It also includes: a robotic arm 18, which is fixedly mounted on the base plate 1 and located on one side of the stamping part mounting rod 3; an industrial camera 19, which is fixedly mounted on the robotic arm 18 and used to detect the hole positions of the stamping part; and a vision inspection device 23, which is fixedly mounted on the base plate 1 and used to receive data from the industrial camera 19 and control the operation of the drive motor 14 for visual inspection.

[0027] It also includes: a mounting frame 20, fixedly mounted on the base plate 1, with the robotic arm 18 and the stamping part mounting rod 3 located inside the mounting frame 20; several ambient lights 21, fixedly mounted on the mounting frame 20; and several protective plates 22, fixedly mounted on the mounting frame 20. By setting up the ambient lights 21, the brightness is increased, making the industrial camera 19 capture images more clearly, facilitating the analysis and judgment of the visual inspection device 23, and avoiding too many misjudgments. By setting up the protective plates 22, the staff can be isolated and warned to prevent accidents.

[0028] This utility model provides a device for detecting the hole position of stamped parts, and its working principle is as follows:

[0029] During the punching inspection of stamped parts, the operator first installs the stamped part onto the stamped part mounting rod 3. Then, the operator places the mounted stamped part mounting rod 3 onto the support plate 2. Next, the end with the friction grooves 9 is pushed into the connecting sleeve 5. The operator then rotates the adjusting sleeve 7 to allow it to enter the connecting sleeve 5. During this process, the inclined plane 8 pushes the clamping plate 6 against the surface of the stamped part mounting rod 3, ultimately securing it. After securing, the robotic arm 18 is activated. The robotic arm 18 drives the industrial camera 19 to take pictures of the secured stamped part from various angles and transmits the data to the vision inspection device 23. The visual inspection system makes a judgment. When some stamped parts cannot be photographed due to their position, the visual inspection device 23 controls the drive motor 14 to start. The drive motor 14 drives the driven gear plate 12 to rotate, so that the push rod 13 enters the actuation groove 11. Under the drive of the driven gear plate 12, the push rod 13 pushes the adjustment plate 10 to rotate and finally disengages from the actuation groove 11, so that the stamped part mounting rod 3 rotates, making it easier to inspect the obscured stamped parts. After the inspection is completed, the staff rotates the adjustment sleeve 7 in the opposite direction to release the restriction on the stamped part mounting rod 3 and removes it. Then, a new batch of stamped part mounting rods 3 with stamped parts fixed are placed for inspection.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
