Description

Technical Field

[0001] This utility model relates to the field of metal stamping parts testing technology, and in particular to a device for testing the punching structure of metal stamping parts. Background Technology

[0002] In modern manufacturing, metal stamping parts are widely used in many fields such as automobiles, electronics, and home appliances. Their quality directly affects the performance and safety of the final product. As a key component of metal stamping parts, the quality inspection of the punching structure is particularly important.

[0003] Traditional metal stamping part punching structure testing devices are complex in operation and maintenance, requiring specialized technicians, which increases the cost and difficulty of use and reduces testing efficiency. Therefore, those skilled in the art provide a metal stamping part punching structure testing device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a punching structure testing device for metal stamping parts. Through the testing structure, it can effectively test the quality of punching structures, reduce testing costs, simplify operation, and thus improve testing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a punching structure detection device for metal stamping parts, comprising a base, a control panel, and a top plate. The control panel is located at the center of one side of the base, and the top plate is located at the upper end of the base. Four drive motors are arranged in a rectangular pattern at the center of the upper surface of the top plate, and four threaded rods are arranged in a rectangular pattern at the center of the lower surface of the top plate. A first moving plate is provided at the front and rear of the center of the lower surface of the top plate. Two of the first moving plates are threadedly connected to the four threaded rods respectively. A horizontal moving component is provided at the center of the interior of the two first moving plates. A second moving block is provided at the center between the two first moving plates, and a detection structure is provided at the center of the interior of the second moving block.

[0006] The detection structure includes an adjustment component and a detection component. The adjustment component is located at the center inside the second moving block, and the detection component is located at the center of the lower end face of the second moving block.

[0007] The adjustment assembly includes a second rotary motor, which is located at the center of one inner sidewall of the second moving block. A second lead screw is provided at the output end of the second rotary motor. One end of the second lead screw is rotatably connected to the other inner sidewall of the second moving block through a bearing. A first sliding groove is provided at the center of the lower end face of the second moving block. A guide block is threadedly sleeved at the center of the outer side of the second lead screw.

[0008] The above technical solution involves a second rotary motor driving a second lead screw to rotate, and a guide block connected to the second lead screw via a threaded connection, which enables the guide block to move. The movement of the guide block then enables the movement and adjustment of the detection component.

[0009] Furthermore, the detection component includes a sleeve, which is disposed at the lower end face of the second moving block. A detection rod is provided at the center of the lower end face of the sleeve. The end of the detection rod passes through the sleeve and extends into the interior of the sleeve, and is slidably connected to the sleeve. A pressure sensor is provided at the center of the upper inner wall of the sleeve. A spring assembly is provided at the center of the lower end face of the pressure sensor. A tapered guide portion is provided at the lower end of the spring assembly.

[0010] With the above technical solution, when the tapered guide of the detection rod contacts the hole of the stamping part, the detection rod slides along the sleeve axis under the push of the drive mechanism. When the hole diameter is too small, the detection rod is blocked and stops, the compression of the spring assembly exceeds the limit, and the pressure sensor detects a sudden increase in pressure value. When the hole diameter is too large, the gap between the detection rod and the hole wall is too large, the spring assembly does not reach the effective compression, and the pressure signal is lower than the set lower threshold. When the position is offset, the inclined surface of the tapered guide automatically corrects the position deviation, so that it can effectively detect the quality of the punched structure, reduce the detection cost, simplify the operation, and thus improve the detection efficiency.

[0011] Furthermore, the horizontal moving assembly includes two first rotary motors, which are respectively located at one side of the center of the rear end face of the two first moving plates, and their ends pass through the rear end face of the two first moving plates to the rear inner wall of the two first moving plates. Each of the output ends of the two first rotary motors is provided with a first lead screw. The front ends of the two first lead screws are rotatably connected to the front inner wall of the two first moving plates through bearings, and each of the two first moving blocks is threaded with a first moving block at its outer center. The two first moving blocks are fixedly connected to a second moving block and slidably connected to the two first moving plates.

[0012] Through the above technical solution, the first rotary motor drives the first lead screw to rotate, which in turn drives the first moving block to move. The movement of the first moving block then enables the movement of the second moving block, and also enables the movement and adjustment of the detection structure.

[0013] Furthermore, a clamping and fixing device is provided at the center of the upper end face of the base. The clamping and fixing device includes two first clamping rods, which are respectively arranged at the front and rear of the center of the upper end face of the base. Four sliding grooves are arranged in a rectangular pattern at the center of the upper end face of the base. Four second moving plates are arranged in a rectangular pattern at the center of the lower inner wall of the base. The four second moving plates are slidably connected to the four sliding grooves and fixedly connected to the two first clamping rods. Strong springs are provided at the center of the front and rear inner walls of the base near both sides. The four strong springs are fixedly connected to the four second moving plates. Square grooves are provided at the center of the front end face of the two first clamping rods.

[0014] With the above technical solution, when the metal stamping part is placed between the two first clamping rods, the strong spring provides inward clamping force to push the second moving plate inward, thereby driving the first clamping rods to clamp the metal stamping part, ensuring that the workpiece will not move or deform during the inspection process.

[0015] Furthermore, a third rotary motor is provided at the center of the inner sidewall of each of the two square grooves, a third lead screw is provided at the output end of each of the two third rotary motors, a connecting post is provided at the end of each of the two third lead screws, and a fourth lead screw is provided at the center of one side of each of the two connecting posts. One end of the fourth lead screw is rotatably connected to the square groove via a bearing. A second clamping rod is threaded onto the outer center of each of the two fourth lead screws on one side and the outer center of each of the two third lead screws on the other side. The two third lead screws are symmetrically arranged with respect to the two fourth lead screws.

[0016] The above technical solution drives the third lead screw to rotate through the output end of the third rotary motor, and then transmits the power through the connecting column, so as to drive the fourth lead screw to rotate. The symmetrical arrangement between the third and fourth lead screws allows them to drive the two second clamping rods to move in opposite directions, thus achieving precise clamping and positioning of the metal stamping parts and improving the accuracy of the inspection process.

[0017] Furthermore, the four drive motors are fixedly connected to the four threaded rods respectively, and are rotatably connected to the top plate via bearings. The lower ends of the four threaded rods are rotatably connected to the base via bearings.

[0018] The above technical solution uses a drive motor to rotate the threaded rod, which enables the first moving plate to move up and down and also enables the movement of the detection structure, thus ensuring that the detection can be completed.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, when the punching structure testing device for metal stamping parts is used, when the tapered guide part of the testing rod contacts the hole position of the stamping part, the testing rod slides along the sleeve axis under the push of the driving mechanism, so that it can effectively detect the quality of the punching structure, reduce the testing cost, simplify the operation, and thus improve the testing efficiency.

[0021] 2. In this utility model, when the metal stamping part is placed between the two first clamping rods, a strong spring provides an inward clamping force to push the second moving plate inward, thereby causing the first clamping rods to clamp the metal stamping part. This ensures that the workpiece will not move or deform during the inspection process. Then, the output end of the third rotary motor drives the third lead screw to rotate, and the transmission is carried out through the connecting column, so that it drives the fourth lead screw to rotate. The third and fourth lead screws then drive the two second clamping rods to move in opposite directions, satisfying the clamping of the metal stamping part on both sides, realizing the precise clamping and positioning of the metal stamping part, thereby improving the accuracy of the inspection process.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-5 This utility model provides an embodiment of a punching structure testing device for metal stamping parts, comprising a base 1, a control panel 2, and a top plate 3. The control panel 2 is located at the center of one side of the base 1, and the top plate 3 is located at the upper end of the base 1. Four drive motors 4 are arranged in a rectangular pattern at the center of the upper surface of the top plate 3, and four threaded rods 5 are arranged in a rectangular pattern at the center of the lower surface of the top plate 3. A first moving plate 6 is provided at the front and rear of the center of the lower surface of the top plate 3. The two first moving plates 6 are threadedly connected to the four threaded rods 5 respectively. A horizontal moving component 7 is provided at the center of the two first moving plates 6, and a second moving block 8 is provided at the center between the two first moving plates 6. A detection structure 9 is provided at the center of the second moving block 8. The detection structure 9 enables effective detection of the punching structure quality, reduces detection costs, simplifies operation, and thus improves detection efficiency.

[0031] Four drive motors 4 are fixedly connected to four threaded rods 5 respectively, and are rotatably connected to the top plate 3 through bearings. The lower ends of the four threaded rods 5 are rotatably connected to the base 1 through bearings. The drive motors 4 drive the threaded rods 5 to rotate, so that they can drive the first moving plate 6 to move up and down, and can also drive the detection structure 9 to move, thereby ensuring that the detection can be completed.

[0032] The horizontal movement assembly 7 includes two first rotary motors 701, which are respectively located at the center of the rear end face of the two first moving plates 6 on one side, and their ends pass through the rear end face of the two first moving plates 6 to the rear inner wall of the two first moving plates 6. Each of the output ends of the two first rotary motors 701 is provided with a first lead screw 702. The front ends of the two first lead screws 702 are rotatably connected to the front inner wall of the two first moving plates 6 through bearings, and the outer center of each first moving block 703 is threadedly sleeved. The two first moving blocks 703 are fixedly connected to the second moving block 8 and slidably connected to the two first moving plates 6. The first rotary motors 701 drive the first lead screws 702 to rotate, so as to drive the first moving blocks 703 to move. The movement of the first moving blocks 703 enables the movement of the second moving block 8 and also enables the movement and adjustment of the detection structure 9.

[0033] like Figure 1 , 3 As shown in Figure 4, a clamping and fixing device 10 is provided at the center of the upper end face of the base 1. The clamping and fixing device 10 includes two first clamping rods 1001, which are respectively located at the front and rear of the center of the upper end face of the base 1. Four sliding grooves 1002 are arranged in a rectangular pattern at the center of the upper end face of the base 1. Four second moving plates 1003 are arranged in a rectangular pattern at the center of the lower inner wall of the base 1. The four second moving plates 1003 are slidably connected to the four sliding grooves 1002 and fixedly connected to the two first clamping rods 1001 respectively. The front of the base 1... Each of the two inner walls is equipped with a strong spring 1004 at the center of both sides. The four strong springs 1004 are fixedly connected to the four second moving plates 1003 respectively. The center of the front end face of each of the two first clamping rods 1001 is provided with a square groove 1005. When the metal stamping part is placed between the two first clamping rods 1001, the strong springs 1004 provide an inward clamping force to push the second moving plate 1003 inward, thereby driving the first clamping rods 1001 to clamp the metal stamping part, ensuring that the workpiece will not move or deform during the inspection process.

[0034] Each of the two square slots 1005 has a third rotary motor 1006 located at the center of its inner sidewall. Each of the two third rotary motors 1006 has a third lead screw 1007 at its output end. Each of the two third lead screws 1007 has a connecting post 1008 at its end. Each of the two connecting posts 1008 has a fourth lead screw 1009 located at the center of one side of its outer side. One end of the fourth lead screw 1009 is rotatably connected to the square slot 1005 via a bearing. A second clamping rod 1010 is threadedly connected to the outer center of each of the two fourth lead screws 1009 (near one side) and the outer center of each of the two third lead screws 1007 (near the other side). Two third lead screws 1007 are symmetrically arranged between two fourth lead screws 1009. The third lead screw 1007 is driven to rotate by the output end of the third rotary motor 1006, and then transmitted through the connecting column 1008, so as to drive the fourth lead screw 1009 to rotate. The symmetrical arrangement between the third lead screw 1007 and the fourth lead screw 1009 also enables the two second clamping rods 1010 to move in opposite directions, thus satisfying the clamping of the metal stamping parts on both sides, achieving precise clamping and positioning of the metal stamping parts, thereby improving the accuracy of the inspection process.

[0035] like Figure 2 , 5 As shown, the detection structure 9 includes an adjustment component and a detection component. The adjustment component is located at the center inside the second moving block 8, and the detection component is located at the center of the lower end face of the second moving block 8. The adjustment component includes a second rotary motor 901, which is located at the center of one inner sidewall of the second moving block 8. A second lead screw 902 is provided at the output end of the second rotary motor 901. One end of the second lead screw 902 is rotatably connected to the other inner sidewall of the second moving block 8 via a bearing. A first sliding groove 903 is provided at the center of the lower end face of the second moving block 8. A guide block 904 is threadedly sleeved at the center of the outer side of the second lead screw 902. The second rotary motor 901 drives the second lead screw 902 to rotate, and the threaded connection between the guide block 904 and the second lead screw 902 enables the guide block 904 to move, and the movement of the guide block 904 enables the movement and adjustment of the detection component.

[0036] The detection assembly includes a sleeve 905, which is located at the lower end face of the second moving block 8. A detection rod 906 is located at the center of the lower end face of the sleeve 905. The end of the detection rod 906 passes through the sleeve 905 and extends into the interior of the sleeve 905, and is slidably connected to the sleeve 905. A pressure sensor 907 is located at the center of the upper inner wall of the sleeve 905. A spring assembly 908 is located at the center of the lower end face of the pressure sensor 907. A tapered guide portion 909 is located at the lower end of the spring assembly 908. When the tapered guide portion 909 of the detection rod 906 contacts the hole of the stamped part, the drive motor... Driven by the mechanism, the detection rod 906 slides axially along the sleeve 905. When the hole diameter is too small, the detection rod 906 is blocked and stops, the compression of the spring assembly 908 exceeds the limit, and the pressure sensor 907 detects the sudden increase in pressure value. When the hole diameter is too large, the gap between the detection rod 906 and the hole wall is too large, the spring assembly 908 does not reach the effective compression, and the pressure signal is lower than the set lower limit threshold. When the position is offset, the inclined surface of the tapered guide 909 automatically corrects the position deviation, so that it can effectively detect the quality of the punched structure, reduce the detection cost, simplify the operation, and thus improve the detection efficiency.

[0037] Working principle: When the metal stamping part punching structure inspection device is used, the metal stamping part is placed between the two first clamping rods 1001. The strong spring 1004 provides inward clamping force, which pushes the second moving plate 1003 inward, thereby driving the first clamping rods 1001 to clamp the metal stamping part. This ensures that the workpiece will not move or deform during the inspection process. Then, the output end of the third rotary motor 1006 drives the third lead screw 1007 to rotate, and then the connecting column 1008 transmits the power, which drives the fourth lead screw 1009 to rotate. The third lead screw 1007 and the fourth lead screw 1009 can drive the two second clamping rods 1010 to move in opposite directions, which satisfies the clamping of the metal stamping part on both sides, realizing the precise clamping and positioning of the metal stamping part, thereby improving the accuracy of the inspection process.

[0038] The drive motor 4 drives the threaded rod 5 to rotate, enabling it to move the first moving plate 6 up and down, and to move the detection structure 9. The first rotary motor 701 drives the first lead screw 702 to rotate, enabling it to move the first moving block 703. The movement of the first moving block 703 enables it to move the second moving block 8, and to adjust the movement of the detection structure 9. The second rotary motor 901 drives the second lead screw 902 to rotate, and the guide block 904 is threadedly connected to the second lead screw 902, enabling it to move. The movement of the guide block 904 enables it to adjust the movement of the detection component.

[0039] When the tapered guide 909 of the detection rod 906 contacts the hole of the stamped part, the detection rod 906 slides axially along the sleeve 905 under the push of the drive mechanism. When the hole diameter is too small, the detection rod 906 is blocked and stops, the compression of the spring assembly 908 exceeds the limit, and the pressure sensor 907 detects the sudden increase in pressure value. When the hole diameter is too large, the gap between the detection rod 906 and the hole wall is too large, the spring assembly 908 does not reach the effective compression, and the pressure signal is lower than the set lower limit threshold. When the position is offset, the inclined surface of the tapered guide 909 automatically corrects the position deviation, so that it can effectively detect the quality of the punched structure, reduce the detection cost, simplify the operation, and thus improve the detection efficiency.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
