Description

Technical Field

[0001] This utility model relates to the field of product positioning and measurement technology, and in particular to a flatness measurement and positioning carrier. Background Technology

[0002] The workpiece is cut from a single sheet of material. The sheet is made of profile and is cut into equal pieces using a saw. These pieces are the workpieces we need. After being cut, the workpieces need to undergo processes such as flatness measurement, marking, and scanning.

[0003] When measuring the flatness of a workpiece, it is necessary to position and fix the workpiece using a fixture before measuring the flatness of both sides. However, existing fixtures can only position the workpiece from both sides, resulting in poor positioning accuracy and an inability to guarantee consistent positional accuracy for each workpiece, thus affecting measurement precision. Furthermore, the length of the workpiece varies depending on its model, necessitating consideration of fixture versatility. Designing a separate positioning fixture for each model would undoubtedly increase costs. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a flatness measurement and positioning vehicle, which solves the problems of poor versatility and poor positioning effect of existing vehicles, thus affecting the measurement accuracy.

[0005] The technical solution of this utility model to achieve the above objectives is a flatness measurement and positioning carrier, comprising:

[0006] A positioning base, wherein one end of the positioning base is provided with a first positioning post for positioning one end of the product to be measured, and one side of the upper part of the positioning base is provided with at least two third positioning posts for positioning one side of the product to be measured.

[0007] An end positioning mechanism, the end positioning mechanism including a slidable second positioning post, the second positioning post being used to position the end of the product to be measured that is away from the first positioning post;

[0008] A side positioning mechanism includes a slidable control plate and a fourth positioning post disposed on the control plate. The fourth positioning post is positioned on the side of the product to be measured away from the third positioning post. The control plate and the end positioning mechanism are in inclined engagement. When the control plate slides, it can control the second positioning post to move away from the first positioning post, and the sliding direction of the control plate is perpendicular to the sliding direction of the end positioning mechanism.

[0009] Multiple laser sensors are respectively set on both sides of the positioning base. The displacement between the laser sensors and different parts of the product's two sides is measured by the multiple laser sensors to determine the flatness of the product's two sides.

[0010] Preferably, the positioning base is fixedly installed on the base plate, and the base plate is provided with support frames on both sides of the positioning base. The multiple laser sensors are respectively horizontally fixed on the two support frames, and the laser emitting ends of the laser sensors on each support frame are flush.

[0011] Preferably, the base plate is provided with at least two slide rails, and the end positioning mechanism and the side positioning mechanism are slidably connected to the slide rails respectively by sliders, and the sliding directions are perpendicular to each other.

[0012] Preferably, the end positioning mechanism further includes a slide and a pressure roller, the second positioning column is vertically fixed on the slide, and the pressure roller is horizontally rotatably connected to the front side of the slide.

[0013] Preferably, the control plate has a notch on the side near the end positioning mechanism, and one side wall of the notch has an inclined surface that cooperates with the pressure roller. During the sliding process, the control plate can squeeze the pressure roller through the inclined surface, causing the end positioning mechanism to move away from the first positioning post.

[0014] Preferably, the slide is provided with guide rods, fixing blocks and springs on both sides. One end of the guide rod is fixedly connected to the slide, and the other end is inserted into the fixing block. The spring is sleeved on the guide rod and can apply a preload to the slide.

[0015] Preferably, the side positioning mechanism further includes a fixed base, which is installed at the rear end of the upper part of the control plate, and the fourth positioning column is horizontally fixed on the fixed base.

[0016] Preferably, the rear end of the control board is connected to a guide rod, the other end of which is inserted into a limiting plate fixed on the base plate. A spring is sleeved on the guide rod, and the spring can apply a preload force to the control board.

[0017] Preferably, a cylinder is provided at the end of the control board away from the guide rod, and the output end of the cylinder is connected to the control board.

[0018] Its advantages over existing technologies are:

[0019] The positioning carrier of this utility model has the advantages of simple structure, high positioning accuracy, and strong versatility, and can meet the clamping and positioning of workpieces of different sizes. After the product to be measured is placed on the positioning base, the first and third positioning columns position the end and side of the product respectively. Then, the second positioning column in the end positioning mechanism and the fourth positioning column in the side positioning mechanism position the other end and the other side of the product respectively to ensure the uniformity of the positioning position. By moving the control plate, which is inclined to engage with the end positioning mechanism, the second positioning column is moved outward, thereby opening the positioning carrier to remove the product. This positioning carrier can position products of different sizes. After the product is positioned, multiple laser sensors located on both sides of the product emit point lasers to different parts on both sides of the product and receive reflected signals. By measuring the displacement between the laser sensors and the product surface, the flatness of the two sides of the product surface is determined. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] like Figures 1-2 As shown, a preferred embodiment of the present invention provides a flatness measurement positioning carrier, which mainly includes a base plate 9, a positioning base 1, a side positioning mechanism 5, an end positioning mechanism 4, and multiple laser sensors 6.

[0028] For details, please refer to Figure 1 The positioning base 1 is fixedly installed on the base plate 9, which is used to place the product 10 to be measured.

[0029] Support frames 7 are provided on both the left and right sides of the positioning base 1. The support frames 7 are fixedly installed on the base plate 9 by screws. Five laser sensors 6 are installed on each support frame 7. The laser sensors 6 are placed horizontally, and the laser sensors 6 on the two support frames 7 correspond to the two sides of the product 10 to be measured.

[0030] like Figure 1 , Figure 2 As shown, the laser emitting ends of the five laser sensors 6 on each support frame 7 are flush to ensure that the point lasers emitted by the five laser sensors 6 are emitted simultaneously. The product 10 to be measured is placed on the positioning base 1 and positioned by the end positioning mechanism 4 and the side positioning mechanism 5. The point lasers emitted by the laser sensors 6 on both sides are reflected by the product surface, and the laser sensors 6 receive the reflected signals. Because the laser sensors 6 on both sides of the product emit lasers to different parts of the product's surface, the flatness of the product's surface can be determined by the laser feedback signals.

[0031] Three slide rails are provided on the base plate 9. Two of the slide rails are located on the same straight line, and the side positioning mechanism 5 is slidably connected to these two slide rails via a slider. The third slide rail is perpendicular to the two slide rails, and the end positioning mechanism 4 is slidably connected to this slide rail via a slider.

[0032] like Figure 3 As shown, a first positioning post 2 and a third positioning post 3 are provided on the positioning base 1. The first positioning post 2 is vertically fixed at one end of the positioning base, that is, the end away from the end positioning mechanism 4, and cooperates with the end positioning mechanism 4 to position both ends of the product 10 to be measured. In this embodiment, there are two third positioning posts 3, which are vertically fixed on one side of the positioning base 1 and are used to position one side of the product 10 to be measured.

[0033] The third positioning post 3 must have at least two posts, but can also have three, four, etc., without specific limitations.

[0034] like Figure 4As shown, the end positioning mechanism 4 mainly consists of a slide block 42, a pressure roller 43, and a second positioning post 41. The slide block 42 is slidably connected to the slide rail on the base plate 9 via a slider, and the second positioning post 41 is vertically fixed on the slide block 42. The second positioning post 41 corresponds to the first positioning post 2. The pressure roller 43 is located on the front side of the slide block 42 (i.e., the side closest to the first positioning post 2) and is horizontally rotatably connected to the slide block 42.

[0035] A fixing block 14, a guide rod 11, and a spring 12 are provided on both sides of the slide 42. The fixing block 14 is fixed to the base plate 9 with screws. One end of the guide rod 11 is fixedly connected to the slide 42, and the other end is inserted into the fixing block 14. When the slide 42 slides, the guide rod 11 plays a guiding role. The spring 12 is sleeved on the guide rod 11, and both ends of the spring 12 abut against the fixing block 14 and the slide 42 respectively. The spring 12 applies a preload force to the slide 42, so that the second positioning post 41 is in the working position (that is, the position where the product 10 to be measured is positioned).

[0036] The positioning base 1 has a groove 101 at the position corresponding to the second positioning post 41, which serves to avoid the movement of the second positioning post 41.

[0037] like Figure 5 As shown, the side positioning mechanism 5 mainly consists of a control plate 52, a fourth positioning post 51, and a fixed base 53. The two ends of the bottom of the control plate 52 are slidably connected to the two slide rails mentioned above via sliders. The fixed base 53 is fixedly mounted on one end of its upper part by screws, that is, the end away from the third positioning post 3. In this embodiment, there are two fourth positioning posts 51, both horizontally fixed on the fixed base 53. These two fourth positioning posts 51 are approximately positioned between the two third positioning posts 3.

[0038] A cylinder 8 is provided on the base plate 9. The output end of the cylinder 8 is connected to the end of the control board 52 away from the fourth positioning post 51. The control board 52 is driven to slide by the cylinder 8 to control the unlocking of the detection fixture.

[0039] A limit plate 15 is also provided on the base plate 9. Two guide rods 11 are fixedly connected to the end of the control plate 52 away from the cylinder 8. The other ends of the two guide rods 11 are inserted and connected to the limit plate 15, and the guide rods 11 serve as guides. A spring 12 is sleeved on each guide rod 11. The two ends of the spring 12 abut against the limit plate 15 and the control plate 52 respectively. The spring 12 will apply a preload to the control plate 52, causing the control plate 52 to slide towards the side where the cylinder 8 is located. At this time, the fourth positioning post 51 is in the working position (that is, the position where the product 10 to be measured is positioned).

[0040] See Figure 4On the control plate 52, there is a notch 521 on the side near the end positioning mechanism 4. The inner wall of the notch 521 has a slope 5211, and the pressure roller 43 at the front end of the slide 42 is in close contact with the slope 5211.

[0041] like Figure 5 As shown, in order to prevent the control plate 52 from sliding off the slide rail under the action of the spring 12, a limit post 13 is also provided on the base plate 9. The limit post 13 is located at the end of the control plate 52 away from the guide rod 11. When the fourth positioning post 51 reaches the working position, the end of the control plate 52 just abuts against the limit post 13.

[0042] When the cylinder 8 controls the control plate 52 to slide, the fourth positioning post 51 will gradually move away from the third positioning post 3. At the same time, the inclined surface 5211 on the control plate 52 will squeeze the pressure roller 43, causing the slide 42 to slide outward. The second positioning post 41 will gradually move away from the first positioning post 2, so that the testing fixture can be opened to place or remove the product.

[0043] When the power to cylinder 8 is removed, the third positioning pin 3 and the second positioning pin 41 will move back to the working position under the action of spring 12.

[0044] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
