Specific embodiments
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0021] As Figures 1 to 5 shown, the present utility model provides a fixing bracket for electric screwdriver detection, including a fixed seat 1. A support plate 3 is arranged on the fixed seat 1. An electric screwdriver body 6 is placed on the support plate 3. The support plate 3 is used for supporting the electric screwdriver body 6. Both sides of the bottom surface of the support plate 3 are fixedly connected with two lifting columns 2 that are slidably arranged on the fixed seat 1. The lifting columns 2 have the function of height adjustment to facilitate the adjustment of the height of the support plate 3. And the lifting columns 2 are existing mature technologies and will not be elaborated here. Fixed frames 4 are fixedly connected to both the front and back surfaces of the support plate 3. A positioning plate 5 is slidably arranged in each fixed frame 4, so that the positioning plate 5 can only slide horizontally in the fixed frame 4. The electric screwdriver body 6 is placed on the support plate 3 and positioned by the two positioning plates 5. A card frame 7 is fixedly connected to the bottom surface of the support plate 3. A sleeve frame 8 is sleeved outside the card frame 7, so that the sleeve frame 8 can slide up and down on the surface of the card frame 7. The inner wall of the sleeve frame 8 is elastically clamped on the card frame 7. When the sleeve frame 8 slides on the card frame 7, it can be limited on the card frame 7, thereby fixing the sleeve frame 8 to ensure that the two positioning plates 5 can normally fix the electric screwdriver body 6. Both bottom ends of the two positioning plates 5 are hinged with connecting plates 9, and the bottom ends of the connecting plates 9 are hinged to the side surface of the sleeve frame 8. When the sleeve frame 8 moves up and down, the connecting plates 9 can drive the positioning plates 5 to slide together.
[0022] As Figure 3 、 Figure 4 and Figure 5As shown in the figure, two opposite swing plates 18 are hinged to the inner wall of the card frame 7. Equal-distance arranged clamping plates 19 are fixedly connected to the mutually remote side surfaces of the two swing plates 18. Pressing blocks 11 are fixedly connected to the bottom ends of the two swing plates 18, and both the pressing blocks 11 and the clamping plates 19 extend to the outside of the card frame 7. A compression spring 20 is fixedly connected between the two swing plates 18. Two opposite clamping blocks 15 are elastically slidable on the inner wall of the sleeve frame 8, and the clamping blocks 15 are clamped on the clamping plates 19. With the above structural arrangement, it is convenient to fix the electric screwdriver body 6 placed on the support plate 3. During specific operation, only need to pull the sleeve frame 8 downward to move, so that the movement of the sleeve frame 8 can simultaneously pull the two connecting plates 9 to move, further enabling the two connecting plates 9 to pull the two positioning plates 5 closer to each other. And the two clamping blocks 15 in the sleeve frame 8 will sequentially slide on each clamping plate 19 and push the two swing plates 18 closer to each other. Until the electric screwdriver body 6 is fixed by the two positioning plates 5, the clamping blocks 15 will also be clamped and limited by the clamping plates 19 to prevent the sleeve frame 8 from rising. When it is necessary to release the fixation of the electric screwdriver body 6 on the support plate 3, only need to make the two swing plates 18 closer to each other, then the two groups of clamping plates 19 can be respectively separated from the clamping blocks 15. Thus, after the sleeve frame 8 moves upward, the two positioning plates 5 are separated from each other to release the fixation of the electric screwdriver body 6.
[0023] As Figure 3 and Figure 5 shown, two opposite guide rods 16 are fixedly connected to the bottom surface of the support plate 3, and the bottom ends of the two guide rods 16 penetrate below the sleeve frame 8. A tension spring 17 is sleeved on the surface of each guide rod 16, and the two ends of the tension spring 17 are respectively fixedly connected to the bottom surface of the support plate 3 and the upper surface of the sleeve frame 8. With the arrangement of the guide rods 16 and the tension springs 17, when a person presses the two pressing blocks 11 to make the clamping plates 19 away from the clamping blocks 15, the positioning of the sleeve frame 8 can be released. Under the elastic pulling force of the tension spring 17, the sleeve frame 8 can be automatically pulled upward, further enabling the two connecting plates 9 to respectively push the two positioning plates 5 away from each other, so as to facilitate the person to take out the electric screwdriver body 6. And the guide rods 16 ensure the stable vertical sliding effect of the sleeve frame 8 without position deviation.
[0024] As Figure 1 and Figure 3 shown, a slide rail 13 is opened on the fixed seat 1, and a guide rod 12 is fixedly connected to the inner wall of the slide rail 13. The bottom end of each lifting column 2 is sleeved on the guide rod 12 and slides in the slide rail 13. With the arrangement of the slide rail 13 and the guide rod 12, it can play a guiding and positioning effect on the lifting column 2, ensuring that the support plate 3 can stably slide on the fixed seat 1 through the lifting column 2, so as to facilitate the connection of the fixed electric screwdriver body 6 with external torque measuring equipment. There is no need for a person to always hold the electric screwdriver body 6. And after the person pushes the electric screwdriver body 6 to move, it is also convenient to press the switch on the electric screwdriver body 6.
[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the bottom end of each lifting column 2 is rotatably connected to two opposite rollers 14, and the rollers 14 are in contact with the upper surface of the fixing seat 1. Through the setting of the rollers 14, the support plate 3 and the lifting column 2 can be pushed, and the rollers 14 can slide stably on the fixing seat 1, thereby ensuring the horizontal stability of the support plate 3 and ensuring that the support plate 3 will not shake.
[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the left and right sides of the sleeve frame 8 are fixedly connected with a paddle 10. Through the setting of the paddle 10, it is convenient for personnel to pull the sleeve frame 8 downward. They only need to pull the two paddles 10 downward with two fingers respectively, thereby making the fixing operation of the electric screwdriver body 6 more convenient.
[0027] like Figure 2 As shown, a plurality of suction cups are fixedly connected to the bottom surface of the fixing seat 1. The setting of the suction cups can improve the stability between the fixing seat 1 and the desktop, and prevent the fixing seat 1 from sliding easily, so that people can take the electric screwdriver body 6 to push it more steadily, and the electric screwdriver body 6 is not easy to shake during operation.
[0028] The working principle and use process of the utility model are as follows: when the torque of the electric screwdriver body 6 needs to be detected by an external torque measuring device, the electric screwdriver body 6 is first placed on the support plate 3, and then the two dial plates 10 are directly toggled to move the sleeve frame 8 downward. When the electric screwdriver body 6 is fixed by the two positioning plates 5, the sleeve frame 8 can be loosened. At this time, the sleeve frame 8 will be connected to the clamping plate 19 through the clamping block 15. Then, the person pushes the electric screwdriver body 6 to connect with the torque measuring device, and presses the switch on the electric screwdriver body 6 to start the electric screwdriver. Whether the torque test of the sub-body 6 is qualified, when the electric screwdriver body 6 completes the test, the electric screwdriver body 6 is pulled out of the torque measuring device, and then the two pressing blocks 11 are directly pressed to make the clamping plate 19 release the clamping limit of the clamping block 15, and the sleeve frame 8 is directly pulled up under the elastic force of the tension spring 17, so that the two positioning plates 5 are automatically away from the electric screwdriver body 6, and then the personnel can directly take out the electric screwdriver body 6. The operation is more convenient, without more other complicated steps, and the detection accuracy of the electric screwdriver body 6 is also guaranteed.
