Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, specifically a universal tooling for testing annular automotive parts. Background Technology

[0002] Automotive parts are the individual units that make up the overall automotive parts manufacturing process and the products that serve that process. After production, parts must be inspected using sophisticated testing fixtures to ensure they meet actual usage standards.

[0003] When inspecting the height of ring-shaped automotive parts, a fixing mechanism is needed to ensure that the parts are in an upright position during inspection. However, in the era of high precision, diverse data needs to be measured during the inspection process, and different positions on the surface of the parts are usually inspected multiple times. Therefore, the fixing position of the parts needs to be adjusted. However, since the parts are fixed by the fixing mechanism, they need to be unloaded from the fixing mechanism first. The process of frequently unloading and adjusting the position of parts is cumbersome, which will prolong the overall inspection process and affect the efficiency of the parts inspection. At the same time, the traditional process requires waiting for a single part to complete all point inspections and be completely unloaded before the next set of parts can be clamped and fixed. The entire inspection process is "intermittent" rather than "automated", resulting in an equipment utilization rate of only about 60%, which seriously restricts the overall efficiency of parts inspection.

[0004] To address these issues, the applicant proposes a universal tooling for the inspection of circular automotive parts, aiming to solve core problems such as intermittent inspection processes and insufficient coverage of diverse data. Utility Model Content

[0005] The purpose of this utility model is to provide a universal tooling for the inspection of annular automotive parts, solving the following technical problems: When inspecting the height of annular automotive parts, a fixing mechanism is required to ensure that the parts are in an upright state during inspection. However, in the era of high precision, diverse data needs to be detected during the inspection process, and different positions on the surface of the parts are usually inspected multiple times. Therefore, the fixing position of the parts needs to be adjusted. However, since the parts are fixed by the fixing mechanism, the parts need to be unloaded from the fixing mechanism first. The process of frequently unloading and adjusting the position of parts is cumbersome, which will prolong the overall process of parts inspection to a certain extent, thus affecting the efficiency of parts inspection. At the same time, the traditional process requires waiting for a single part to complete all point inspections and be completely unloaded before the next set of parts can be clamped and fixed. The entire inspection process is "intermittent" rather than "automated", resulting in the equipment utilization rate being only about 60%, which seriously restricts the overall efficiency of parts inspection.

[0006] The objective of this utility model can be achieved through the following technical solutions: A universal tooling for testing annular automotive parts includes a worktable with a through hole at the upper end and an annular groove on the inner side wall of the through hole. A first motor is fixedly installed at the bottom of the groove, and a disc is fixedly installed on the output shaft of the first motor. The outer edge of the disc is engaged in the annular groove, and a rotating component is installed at the upper end of the disc. The rotating assembly includes a second motor fixedly mounted on the upper end of the disk, a gear turntable fixedly mounted on the output shaft of the second motor, a ring fixedly mounted on the upper end of the disk, a plurality of support shafts rotatably mounted on the upper end of the ring, a driven gear plate fixedly mounted on the upper end of the plurality of support shafts, and the plurality of driven gear plates meshing with the gear turntable. An L-shaped bracket is fixedly installed at the upper end of the workbench, and multiple height detection mechanisms are installed at the lower end of the L-shaped bracket.

[0007] As a further embodiment of this utility model: multiple support shafts are arranged in a ring on the outer edge of the gear turntable.

[0008] As a further embodiment of this utility model: a lifting cylinder is fixedly installed at the lower end of the L-shaped bracket, a guide plate is fixedly installed at the end of the piston rod of the lifting cylinder, an arc plate is fixedly installed at the lower end of the guide plate, and a plurality of height detection mechanisms are arranged in a circular array at the lower end of the arc plate.

[0009] As a further embodiment of this invention, the distance between the plurality of height detection mechanisms is adapted to the plurality of driven gear discs on one side of the gear turntable.

[0010] As a further embodiment of this utility model: a sliding groove is provided on one side of the L-shaped bracket, and one end of the guide plate extends into the sliding groove and is slidably engaged with it.

[0011] As a further embodiment of this utility model: a fixing seat is fixedly provided at the upper end of each of the plurality of driven gear discs, and clamping components are symmetrically provided at both ends of the fixing seat; The clamping assembly includes compression springs fixedly mounted on the outer surface of the fixed base. One end of each of the two compression springs is fixedly provided with a pull ring, and one end of each of the two pull rings is fixedly provided with a connecting rod. One end of each of the two connecting rods passes through the side wall of the fixed base and is fixedly provided with a clamping plate inside it.

[0012] As a further embodiment of this utility model, both clamping plates are arc-shaped.

[0013] As a further embodiment of this utility model, rubber pads are fixedly provided on the inner opposing surfaces of the two clamping plates.

[0014] As a further embodiment of this utility model: a controller and a display screen are provided on one side of the L-shaped bracket.

[0015] The beneficial effects of this utility model are: (1) This utility model utilizes the interval time and area division of the dual motor rotation to construct a streamlined operation mode in which inspection and loading / unloading are carried out in parallel. The first motor drives the disc to transfer the clamped parts to the inspection area. The second motor controls the rotation angle and frequency according to the inspection frequency requirements. During the interval when the lifting cylinder drives the inspection mechanism to complete the inspection, the fixed seat on the other side of the gear turntable, which is not in the inspection area, can simultaneously carry out the loading or unloading of parts. By precisely controlling the rotation interval time of the second motor to match the longest time required for loading and unloading, the inspection and loading / unloading process is ensured to be without waiting or stagnation, which greatly improves the overall inspection efficiency and breaks through the bottleneck of the traditional serial operation of loading and unloading after inspection. At the same time, the driven gear disc drives the fixed seat to rotate, which can simultaneously meet the needs of diverse inspection data and adapt to the development needs of the high-precision era.

[0016] (2) This utility model tooling achieves stable adaptation and accurate detection of ring parts of different specifications through a composite structure of dual motor drive and elastic clamping. On the one hand, the symmetrical arc-shaped clamping plate on the fixed seat, together with the compression spring, can adjust the clamping distance by pulling the pull ring to form concentric circle clamping spaces of different diameters, which can adapt to ring automotive parts of various sizes and solve the limitation of traditional tooling that is used only once. On the other hand, the height detection mechanism of the ring array at the lower end of the arc plate corresponds precisely to the fixed seat below. Combined with the trajectory constraint of the guide plate by the sliding groove on the L-shaped bracket, it ensures that each workpiece to be detected can be accurately covered when the lifting cylinder drives the detection mechanism to move down. At the same time, the rubber pad avoids damage to the surface of the parts during the clamping process, forming a synergistic innovation in universality, accuracy and protection.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0023] In the field of inspection tooling technology, when inspecting the height of ring-shaped automotive parts, a fixing mechanism is required to ensure that the parts are in an upright position during inspection. However, in the era of high precision, diverse data needs to be measured during the inspection process, and different positions on the surface of the parts are usually inspected multiple times. Therefore, the fixing position of the parts needs to be adjusted. However, since the parts are fixed by the fixing mechanism, the parts need to be unloaded from the fixing mechanism first. The process of frequently unloading and adjusting the position of parts is cumbersome, which will prolong the overall process of parts inspection to a certain extent, thus affecting the efficiency of parts inspection. At the same time, the traditional process requires waiting for a single part to complete all point inspections and be completely unloaded before the next set of parts can be clamped and fixed. The entire inspection process is "intermittent" rather than "automated", resulting in the equipment utilization rate only reaching about 60%, which seriously restricts the overall efficiency of parts inspection.

[0024] Therefore, this utility model addresses the aforementioned problems of traditional ring-shaped automotive component height detection devices by effectively solving core issues such as intermittent automotive component detection processes and insufficient data diversity coverage through innovative structural design. The specific implementation method is as follows: Example 1: Please refer to Figure 1 , Figure 2 As shown, a universal tooling for testing annular automotive parts includes a workbench 1, with a through hole 2 at the upper end of the workbench 1, an annular groove 3 on the inner side wall of the through hole 2, a first motor 4 fixedly installed at the bottom of the groove of the through hole 2, and a disc 5 fixedly installed on the output shaft of the first motor 4, the disc 5 being engaged in the annular groove 3. In this embodiment, the first motor 4 drives the disc 5 to rotate within the annular groove 3. The annular groove 3 ensures that the rotation center of the disc 5 is completely aligned with the center of the through hole 2, preventing the position of the detected component from shifting due to the eccentric rotation of the disc 5, which would affect the detection accuracy (e.g., distortion of the component height measurement result). At the same time, the bottom of the annular groove 3 and the lower end face of the disc 5 form a support surface, which can share the weight of the disc 5 and the component, reduce the axial load on the output shaft of the first motor 4, and further improve the overall stability of the tooling when bearing heavier components.

[0025] Further, please refer to Figure 3 As shown, a rotating assembly 6 is provided at the upper end of the disc 5. The rotating assembly 6 is used to realize the circumferential rotation of multiple annular automotive parts. The rotating assembly 6 includes a second motor 61 fixedly installed at the upper end of the disc 5. A gear turntable 62 is fixedly installed on the output shaft of the second motor 61. A ring 63 is fixedly installed at the upper end of the disc 5. The second motor 61 is placed in the central hole of the ring 63. Multiple support shafts 64 are symmetrically rotated around the upper end of the ring 63. The multiple support shafts 64 are arranged in a ring around the outside of the gear turntable 62. A driven gear plate 65 is fixedly installed at the upper end of the multiple support shafts 64. The multiple driven gear plates 65 mesh with the gear turntable 62. In this embodiment, the second motor 61 serves as a power source to drive the gear disk 62 on the output shaft to rotate. Since multiple ring-shaped support shafts 64 located outside the gear disk 62 are equipped with driven gear disks 65 at their upper ends, and all driven gear disks 65 mesh with the gear disk 62, the rotation of the gear disk 62 will synchronously drive the multiple driven gear disks 65 to rotate. This enables the circumferential rotation of multiple ring-shaped automotive parts through the support shaft 64 (the lower end of the driven gear disk 65 is rotatably connected to the ring 63 through the support shaft 64 to ensure rotational stability).

[0026] Further, please refer to Figure 4As shown, a fixed seat 7 is fixedly installed at the upper end of a plurality of driven gear discs 65. Clamping components 8 are symmetrically arranged at both ends of the fixed seat 7. The clamping components 8 include compression springs 81 fixedly installed on the outer surface of the fixed seat 7. Pull rings 82 are fixedly installed at one end of each of the two compression springs 81. Connecting rods 83 are fixedly installed at one end of each of the two pull rings 82. The connecting rods 83 are sleeved inside the compression springs 81. Clamping plates 84 are fixedly installed inside the two connecting rods 83 through the side wall of the fixed seat 7. Both clamping plates 84 are arc-shaped. Rubber pads are fixedly installed on the inner side walls of the two symmetrical clamping plates 84. In this embodiment, pulling the two symmetrical pull rings 82 causes the connecting rod 83 to move backward, and the connecting rod 83 causes the clamping plate 84 to move backward. The two symmetrical clamping plates 84 form concentric circles of different diameters to clamp and fix the annular automotive parts of different sizes. The pull rings 82 stretch and compress the spring 81, and the spring 81 undergoes elastic deformation. When the annular automotive parts are placed inside the fixing seat 7, the pull rings 82 are released, and the spring 81 compresses and drives the clamping plate 84 to move. The two symmetrical clamping plates 84 stably clamp the parts. The rubber material is soft and has a certain elasticity. When it comes into contact with the surface of the annular automotive parts, it can avoid the clamping plate 84 from making direct hard contact with the parts. It can effectively prevent mechanical damage such as scratches and indentations on the surface of the parts due to clamping pressure. It is especially suitable for automotive parts with high surface precision requirements.

[0027] During the inspection of the ring-shaped automotive parts, the first motor 4 drives the disc 5 to rotate, transferring the clamped parts to the inspection area. The rotation frequency of the second motor 61 is controlled according to the number of diverse data points to be inspected. If the number of diverse data points is N, the second motor 61 rotates N-1 times, with each rotation angle being 360 / (N-1) degrees. For example, if the number of diverse data points is 3, the second motor 61 rotates twice, with each rotation angle being 120°. While the second motor 61 is rotating, the lifting cylinder 1... The lifting cylinder 10 drives the height detection mechanism 13 to move upward. When the rotation stops, the lifting cylinder 10 drives the height detection mechanism 13 to move downward to complete the data detection. At the same time, during the gap in the process of the lifting cylinder 10 moving downward, the fixed seat 7 at the upper end of the multiple driven gear disks 65 in the non-detection area on the other side of the gear turntable 62 can perform clamping and loading work. The interval time of the second motor 61 rotation meets the maximum time required for clamping or unloading, so as to ensure that the parts can complete the unloading and loading work quickly when the rotation stops, realizing assembly line operation.

[0028] Example 2: Based on Example 1, please refer to... Figure 1 , Figure 5As shown, an L-shaped bracket 9 is fixed to the upper end of the workbench 1 by multiple fastening bolts. A lifting cylinder 10 is fixed to the lower end of the L-shaped bracket 9. A guide plate 11 is fixed to the end of the piston rod of the lifting cylinder 10. An arc-shaped plate 12 is fixed to the lower end of the guide plate 11. Multiple height detection mechanisms 13 are arranged in a circular array at the lower end of the arc-shaped plate 12. The multiple height detection mechanisms 13 are arranged in a circular array and are adapted to the multiple fixed seats 7 below, ensuring that the workpiece to be inspected on each fixed seat 7 can be covered and inspected by the corresponding height detection mechanism 13, ensuring the comprehensiveness of the inspection range and the accuracy of the inspection results. To improve the stability of the arc-shaped plate 12 during the lifting process and avoid deviation or shaking, a sliding groove 14 adapted to the guide plate 11 is opened on one side of the L-shaped bracket 9. One end of the guide plate 11 extends into the sliding groove 14, and through a sliding snap-fit ​​engagement, the arc-shaped plate 12 can move smoothly along the trajectory of the sliding groove 14 under the drive of the lifting cylinder 10, further improving the overall operating accuracy of the structure. A controller and a display screen 15 are provided on one side of the L-shaped bracket 9. The controller can control the movement of the lifting cylinder 10 and the working status of the height detection mechanism 13, while the display screen can display the detection data of the height detection mechanism 13 in real time, so that the operator can intuitively obtain relevant information and perform subsequent operations. In this embodiment, the lifting cylinder 10 drives the guide plate 11 at the end of the piston rod to move up and down precisely, thereby driving the arc plate 12 tightly connected to the lower end of the guide plate 11 to move synchronously. Multiple height detection mechanisms 13 arranged in a circular array at the lower end of the arc plate 12 can fully cover the workpieces to be detected on each fixed seat 7 to ensure detection accuracy. The height detection mechanism 13 is existing technology, and its model can be selected, such as DeepVision Intelligent SD33-195. At the same time, the inner side wall of the L-shaped bracket 9 is adapted to the sliding groove 14 of the guide plate 11, which restricts its movement trajectory by sliding and engaging with the guide plate 11, avoiding deviation and shaking of the guide plate 11 during lifting and lowering, thereby improving the running accuracy. In addition, the controller on one side of the L-shaped bracket 9 can adjust the action of the lifting cylinder 10 and the working status of the height detection mechanism 13, and the display screen displays the detection data in real time, which makes it convenient for operators to intuitively obtain information and carry out subsequent operations, thus achieving stable and accurate detection of the workpiece height.

[0029] Example 3: Based on Examples 1 and 2, please refer to... Figure 1 - Figure 5As shown, in use, the first motor 4 drives the disc 5 to rotate, transferring the clamped automotive parts to the inspection area. The lifting cylinder 10 drives the height detection mechanism 13 to complete the height detection of the automotive parts. At the same time, during the inspection, the lifting cylinder 10 drives the height detection mechanism 13 to complete the inspection gap. The fixed seat 7 on the other side of the gear turntable 62, which is not in the inspection area, can simultaneously perform the loading or unloading operation of the parts. By precisely controlling the rotation gap time of the second motor 61, it matches the longest time required for loading and unloading, ensuring that the inspection and loading / unloading process is without waiting or stagnation, greatly improving the overall inspection efficiency and breaking through the bottleneck of the traditional tooling inspection and then loading / unloading serial operation. At the same time, the driven gear disc 65 drives the fixed seat 7 to rotate, which can simultaneously meet the needs of diverse inspection data and adapt to the development needs of the high-precision era. The symmetrical arc-shaped clamping plate 84 on the fixed base 7, together with the compression spring 81, can adjust the clamping distance by pulling the pull ring 82 to form concentric circle clamping spaces of different diameters, which can be adapted to various sizes of ring-shaped automotive parts, and solve the limitation of traditional tooling that is only used once.

[0030] In this embodiment, all the various motors, lifting and telescopic mechanisms, and height detection mechanisms involved in this utility model are electrically connected to the controller, and all of them are existing technologies that can be fully implemented by those skilled in the art, so there is no need to elaborate. The content protected by this utility model does not involve any improvement to the internal structure and method. It should be noted that the standard parts used in this utility model can all be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, which will not be described in detail here.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
