Description

Technical Field

[0001] This utility model belongs to the field of workpiece inspection technology, specifically relating to a workpiece rotating bracket with an elastic square probe. Background Technology

[0002] Workpiece inspection refers to a series of checks, tests, and evaluations performed on workpieces produced during the manufacturing process to ensure they meet design requirements and quality standards. This process is crucial in many manufacturing industries, especially in manufacturing, automotive, aerospace, and machinery sectors.

[0003] In the fields of machining and precision manufacturing, the visual inspection of products before they leave the production line, such as checking for defects like burrs, cracks, and missing parts, requires the use of a fixture for a comprehensive inspection of the product's appearance. However, some simple inspection fixtures are mostly fixed structures and can only inspect one or a few sides of the workpiece, unable to perform rotational inspections. When multiple sides of a workpiece need to be inspected, the workpiece must be removed from the fixture and re-clamped, a cumbersome process prone to introducing secondary clamping errors, leading to unreliable inspection results and low efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a workpiece rotation bracket with an elastic square probe, which can adaptively fix workpieces of different lengths under the elastic force of a spring, and can flexibly rotate and detect the workpiece, and re-clamp the workpiece to reduce the time for workpiece processing and improve workpiece detection efficiency.

[0005] The specific technical solution adopted by this utility model is as follows: A workpiece rotation bracket with an elastic square probe includes a base and two support frames. Two support frames are mounted on the top of the base. An automatic positioning mechanism is provided on the inner side of each support frame. The automatic positioning mechanism includes a rotating circular frame, a central shaft, positioning frames, a compression spring, connecting rods, and inspection mirrors. The two rotating circular frames are respectively connected to the inner sides of the two support frames via bearings. One end of each of the two central shafts is located on the outer side of the two support frames, and the other end of each central shaft passes through the two support frames and the rotating circular frames, extending to the inner side of the two rotating circular frames. The two positioning frames are respectively fixedly connected to one end of each of the two central shafts. One end of each compression spring is fixedly connected to the inner wall of the left rotating circular frame, and the other end of each compression spring is fixedly connected to the outer side of the left positioning frame. One end of each of the two connecting rods is connected to the side surface of the two rotating circular frames, and the two inspection mirrors are respectively fixedly connected to the other ends of the two connecting rods.

[0006] Preferably, the base is provided with an adjustment mechanism, which includes a transverse groove, a bidirectional lead screw, and connecting blocks. The transverse groove is opened at the top of the base. One end of the bidirectional lead screw is connected to the inner wall of the transverse groove through a bearing. The other end of the bidirectional lead screw passes through the transverse groove and extends to the outside of the base. The two connecting blocks are respectively fixedly connected to the bottom of the two support frames. Both connecting blocks are threaded to the surface of the bidirectional lead screw and slidably connected to the inside of the transverse groove.

[0007] Preferably, each of the two positioning frames has two positioning plates inside, both of which are slidably connected to the inside of the positioning frame. The outer sides of each of the two positioning plates are connected to adjusting screws via bearings. The other ends of the two adjusting screws pass through to the front and rear sides of the positioning frame, respectively. The two adjusting rods are threadedly connected to the front and rear sides of the positioning frame, respectively.

[0008] Preferably, a knob is fixedly connected to one end of both the bidirectional lead screw and the adjusting screw, and the knob is circular in shape.

[0009] Preferably, the side surfaces of the two rotating circular frames are provided with annular grooves, and one end of each of the two connecting rods is slidably connected to the inside of the annular groove.

[0010] Preferably, the top of the base is provided with auxiliary scale lines, which are located on the front and rear sides of the top of the base, respectively.

[0011] Preferably, the positioning frame is square in shape, and the positioning plate is made of elastic material.

[0012] The technical effects achieved by this utility model are as follows: In this invention, when a workpiece needs to be positioned on a support frame for inspection, one end of the workpiece can be placed inside the right-side positioning frame. Then, another positioning frame is pressed outwards, causing it to compress the compression spring and the left-side central shaft. Simultaneously, the left-side central shaft and positioning frame are pushed outwards. The other end of the workpiece is then positioned inside another positioning frame. Under the rebound force of the compression spring, the left-side central shaft and positioning frame are pushed inwards to compress the workpiece. Thus, the workpiece is automatically squeezed and positioned between the two positioning frames under the thrust of the compression spring. This allows for surface inspection of the workpiece. During inspection, the workpiece can also be rotated. The rotation of the workpiece will cause the two positioning frames, the central shaft, the rotating frame, and the compression spring to rotate simultaneously. This allows for 360-degree rotation of the workpiece and omnidirectional inspection. Furthermore, the inspection mirror can reflect or magnify the surface features of the workpiece, providing precise visual feedback and helping the operator to observe the surface of the inspected workpiece more precisely.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1-4As shown, a workpiece rotating support with an elastic square probe includes a base 1 and two support frames 2. Both support frames 2 are mounted on the top of the base 1. An automatic positioning mechanism is provided on the inner side of each support frame 2. The automatic positioning mechanism includes a rotating circular frame 201, a central shaft 202, a positioning frame 203, a compression spring 204, a connecting rod 205, and a detection mirror 206. The two rotating circular frames 201 are respectively connected to the inner sides of the two support frames 2 via bearings. One end of each of the two central shafts 202 is located on the outer side of the two support frames 2, and the other end of each central shaft 202 passes through the two support frames 2 and the rotating circular frames 201, extending to the inner side of both rotating circular frames 201. Two positioning frames 203 are fixedly connected to one end of each of the two central shafts 202. One end of the compression spring 204 is fixedly connected to the inner wall of the left rotating circular frame 201, and the other end of the compression spring 204 is fixedly connected to the left positioning frame 203. On the outside, one end of each of the two connecting rods 205 is connected to the side surface of the two rotating circular frames 201, and the two inspection mirrors 206 are fixedly connected to the other end of the two connecting rods 205. With the cooperation of the automatic positioning mechanism, it can automatically adapt to and fix workpieces of different sizes under the elastic force of the compression spring 204. Under the elastic force of the compression spring 204, the left positioning frame 203 and the central shaft 202 are pushed inward, which can quickly and automatically position the workpiece between the two positioning frames 203. Then, the workpiece can be rotated flexibly, and the two positioning frames 203 and the central shaft 202 can be rotated 360 degrees inside the support frame 2. The angle of the workpiece can be quickly adjusted and inspected. Combined with the fact that the inspection mirror 206 can magnify or reflect the local surface features of the workpiece, the surface of the workpiece can be observed and inspected more finely, ensuring that every angle and detail can be inspected. There is no need to frequently adjust the support or re-clamp the workpiece, which can further improve the efficiency of workpiece inspection.

[0017] like Figure 1As shown, the base 1 is equipped with an adjustment mechanism, which includes a transverse groove 101, a double-acting lead screw 102, and connecting blocks 103. The transverse groove 101 is located at the top of the base 1. One end of the double-acting lead screw 102 is connected to the inner wall of the transverse groove 101 via a bearing, and the other end of the double-acting lead screw 102 passes through the transverse groove 101 and extends to the outside of the base 1. Two connecting blocks 103 are fixedly connected to the bottom of the two support frames 2, respectively. Both connecting blocks 103 are threaded to the surface of the double-acting lead screw 102 and slidably connected to the inside of the transverse groove 101. This mechanism is used for inspecting workpieces that are short or long. During testing, the operator can adjust the distance between the two support frames 2. Adjustment can be made by rotating the bidirectional lead screw 102 clockwise. This rotation causes the two threaded connecting blocks 103 to move inwards simultaneously within the transverse groove 101, thus reducing the distance between the two support frames 2 and making it suitable for shorter workpieces. Rotating the bidirectional lead screw 102 counterclockwise reverses the process, increasing the distance between the two support frames 2 and making it suitable for longer workpieces. This provides high flexibility for testing various types of workpieces, increasing the versatility and applicability of the testing bracket.

[0018] like Figure 1 and Figure 4 As shown, two positioning plates 301 are respectively installed inside the two positioning frames 203. Both positioning plates 301 are slidably connected inside the positioning frames 203. The outer sides of the two positioning plates 301 are connected to adjusting screws 302 through bearings. The other ends of the two adjusting screws 302 pass through the front and rear sides of the positioning frames 203 respectively. The two adjusting rods are threaded to the front and rear sides of the positioning frames 203 respectively. After the workpiece is squeezed and positioned inside the two positioning frames 203, the operator can rotate the adjusting screws 302 to drive the positioning plates 301 to move parallel inside the positioning frames 203. In this way, workpieces of different sizes can be fixed inside the positioning frames 203, which greatly improves the versatility of the inspection bracket and is suitable for workpieces of various types and specifications.

[0019] like Figure 1 As shown, a knob 4 is fixedly connected to one end of both the bidirectional lead screw 102 and the adjusting screw 302. The knob 4 is circular in shape. The knob 4 provides workers with a more precise adjustment method. Compared with the traditional manual rotation method, the knob 4 allows workers to make fine adjustments more easily, avoiding positional errors caused by uneven force or improper operation, ensuring the accuracy of adjustment. Moreover, by rotating the knob 4, the operator can control the adjustment process without using other tools or cumbersome operating steps.

[0020] like Figure 4As shown, both rotating circular frames 201 have annular grooves 5 on their side surfaces. One end of each of the two connecting rods 205 is slidably connected to the inside of the annular grooves 5. When inspecting local features on the workpiece surface through the inspection mirror 206, the connecting rods 205 can be pulled to slide on the surface of the annular grooves 5. Rotating the connecting rods 205 while sliding in the annular grooves 5 can adjust the position and angle of the inspection mirror 206. At the same time, the connecting rods 205 can extend and retract, making the adjustment of the inspection mirror 206 more precise and flexible. By rotating or extending the connecting rods 205, the operator can more accurately position the inspection mirror 206 to ensure that it can accurately align with the local features of the workpiece, thereby improving the inspection accuracy.

[0021] like Figure 1 As shown, the top of the base 1 is provided with auxiliary scale lines 6, which are located on the front and rear sides of the top of the base 1. By comparing the scale lines on the front and rear sides, the operator can more accurately adjust the distance between the two support frames 2. The distance between the support frames 2 can be quickly adjusted by directly comparing the scale lines, without relying on complicated tools or repeated measurements, which simplifies the operation process and improves work efficiency.

[0022] like Figure 1 and Figure 4 As shown, the positioning frame 203 is square in shape, and the positioning plate 301 is made of elastic material. The design of the square positioning frame 203 allows for accurate detection of whether the end of the workpiece is square in a short time, reducing the process of manual judgment and adjustment, and significantly improving detection efficiency and operation efficiency. At the same time, the positioning plate 301 is made of elastic material, which can adapt to certain shape changes or small workpiece errors. When the end of the workpiece is slightly deformed, the elastic plate can better accommodate these changes and still maintain an effective positioning function, thereby improving the overall adaptability of workpiece detection.

[0023] The working principle of this utility model is as follows: When it is necessary to position the workpiece on the support frame 2 and perform inspection, one end of the workpiece can be placed inside the right positioning frame 203 first. Then, the other positioning frame 203 is squeezed outward, and the positioning frame 203 squeezes the compression spring 204 and the left central shaft 202. At the same time, the left central shaft 202 and the positioning frame 203 are pushed outward. Then, the other end of the workpiece is positioned inside the other positioning frame 203, and under the rebound force of the compression spring 204, the left central shaft 202 and the positioning frame 203 are pushed inward. By pressing the workpiece, the workpiece can be automatically squeezed and positioned between the two positioning frames 203 under the thrust of the compression spring 204. This allows for surface inspection of the workpiece. During inspection, the workpiece can also be rotated. The rotation of the workpiece will cause the two positioning frames 203, the central shaft 202, the rotating circular frame 201, and the compression spring 204 to rotate simultaneously. This allows the workpiece to be rotated 360 degrees and inspected from all angles. The inspection mirror 206 can reflect or magnify the surface features of the workpiece to provide accurate visual feedback, helping the operator to observe the surface of the inspected workpiece more precisely.

[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
