Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all 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 protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides the following technical solution: a support arm measuring fixture, including a base plate 1, a base plate 2, and a support arm workpiece blank 12. A support plate 3 is fixedly connected to the upper surface of the base plate 1. A sliding groove 4 is provided on the side of the support plate 3. A slider 5 is slidably connected inside the sliding groove 4. A measuring device body 6 is fixedly connected to one side of the slider 5. A connecting rod 7 is fixedly connected to the other side of the slider 5. A driving block 8 is fixedly connected to one end of the connecting rod 7. An mounting plate 9 is fixedly installed on one side of the support plate 3. A motor 10 is fixedly installed inside the mounting plate 9. A lead screw 11 is fixedly connected to the output end of the motor 10. Both the upper surfaces of the first plate 1 and the second plate 2 are provided with sliding grooves 13. A blank positioning plate 14 is slidably installed inside the sliding grooves 13. A support frame 15 is fixedly connected to the upper surface of the second plate 2. A motor 16 is fixedly installed on the top of the support frame 15. A rotating shaft 17 is fixedly connected to the output end of the motor 16. A cleaning brush head 18 is fixedly connected to the bottom end of the rotating shaft 17. A gear 19 is fixedly connected to the surface of the rotating shaft 17. A pulley 20 is fixedly connected to the surface of the rotating shaft 17. A transmission belt 21 is sleeved inside the pulley 20. A sliding plate 22 is installed inside the second plate 2. Double-sided adhesive tape 23 is adhered to the upper surface of the sliding plate 22.

[0022] In this embodiment, the rotation of the lead screw 11 driven by the motor 10 facilitates the translation of the measuring device body 6, thereby enabling the measuring device body 6 to scan and measure the dimensions of the support arm workpiece blank 12. The support arm workpiece blank 12 can be laid flat through the adaptation of the positioning groove 27 and the positioning protrusion 26. Both the positioning protrusion 26 and the positioning groove 27 are rectangular, which can prevent the support arm workpiece blank 12 from moving. The blank positioning plate 14 can be translated through the slide groove 13, thereby moving to the bottom of the cleaning brush head 18. The motor 16 drives a rotating shaft 17 to rotate, and the rotating shaft 17 can make all the cleaning brush heads 18 rotate through the cooperation of the gear 19, pulley 20 and transmission belt 21. The rotating cleaning brush head 18 can clean the surface of the blank positioning plate 14, and the swept impurities can be absorbed by the double-sided tape 23 on both sides.

[0023] Specifically, the lead screw 11 passes through and is threadedly connected to the drive block 8. A horizontal rod 24 is fixedly connected to one side of the mounting plate 9, so that the motor 10 drives the lead screw 11 to rotate. The lead screw 11 can drive the drive block 8 to translate along the horizontal rod 24. The horizontal rod 24 can prevent the drive block 8 from being driven to rotate by the lead screw 11, which is conducive to the formation of a force between the drive block 8 and the lead screw 11.

[0024] Specifically, a support rod 25 is fixedly connected to the inner side of the support frame 15, and the rotating shaft 17 is rotatably installed inside the support rod 25. The support rod 25 can support the rotating shaft 17.

[0025] Specifically, gears 19 are grouped in groups of three, with the middle gear 19 meshing with the gears 19 on both sides. Thus, the rotating gear 19 driven by the transmission belt 21 can drive all the gears 19 in the same group to rotate.

[0026] Specifically, a positioning protrusion 26 is fixedly connected to the upper surface of the blank positioning plate 14, and a positioning groove 27 is opened on the surface of the support arm workpiece blank 12. Both the positioning protrusion 26 and the positioning groove 27 are rectangular, which can facilitate the prevention of movement of the support arm workpiece blank 12.

[0027] Specifically, the second base plate 2 can be spliced ​​with the first base plate 1. The splicing facilitates the sliding of the blank positioning plate 14 to the bottom of the cleaning brush head 18. Bolts 28 are inserted at the splicing point to prevent the second base plate 2 from separating from the first base plate 1.

[0028] Specifically, the skateboard 22 and double-sided tape 23 are located on both sides of the cleaning brush head 18 of the array, so that the impurities swept by the cleaning brush head 18 can fall onto the double-sided tape 23 and then adhere to the double-sided tape 23 to prevent them from scattering.

[0029] The working principle or usage process of this utility model is as follows: First, the base plate 2 is spliced ​​with the base plate 1. Then, bolts 28 are inserted. Next, the blank positioning plate 14 is slidably installed through the sliding groove 13. Then, the support arm workpiece blank 12 can be placed on the blank positioning plate 14 through the positioning groove 27. The positioning groove 27 and the positioning protrusion 26 are both rectangular, which helps to prevent the support arm workpiece blank 12 from moving. Then, the motor 10 can be started to drive the lead screw 11 to rotate, thereby driving the measuring device body 6 to translate. This allows the measuring device body 6 to scan and measure the dimensions of the support arm workpiece blank 12. The scan measurement signal can be fed back to the processing equipment, which can then measure the dimensions. The dimensions of the support arm workpiece blank 12 are obtained and displayed. Support arm workpiece blanks 12 that do not meet the dimensions are removed and reshaped. The blank positioning plate 14 can be moved to the bottom of the cleaning brush head 18 by translation. The start motor 16 drives a rotating shaft 17 to rotate. The rotating shaft 17, through the cooperation of gear 19, pulley 20 and transmission belt 21, can make all the cleaning brush heads 18 rotate. The rotating cleaning brush head 18 can clean the surface of the blank positioning plate 14. The cleaned impurities can be absorbed by the double-sided tape 23 on both sides, thereby avoiding impurities from affecting the dimension data of the support arm workpiece blank 12. The electrical equipment in this device is all externally powered and is controlled by the matching control switch to operate and shut down.

[0030] Finally, it should be noted that the above descriptions are merely preferred embodiments of this utility model and are not intended to limit the utility model. The selection and detailed description of these embodiments in this specification are for the purpose of better explaining the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
