[0035] As Figures 1-4 As shown in the figure, it shows an internal hexagonal bolt head polishing equipment in an embodiment of the present disclosure, which comprises:
[0036] The device frame 1 and the door-shaped frame 2 are fixed on the device frame 1;
[0037] A pair of conveying belts 3 are arranged on the surface of the device frame 1, and a clamping assembly 5 is arranged on the conveying belts 3 and the device frame 1;
[0038] A telescopic air cylinder 4 is installed on the top of the door-shaped frame 2, and a polishing assembly 6 is arranged on the output end of the telescopic air cylinder 4;
[0039] The clamping assembly 5 comprises a plurality of clamping grooves 5-1 evenly arranged on the surface of the conveying belt 3, a rectangular opening 5-2 arranged on the surface of the device frame 1, a plurality of fixing blocks 5-3 arranged on the bottom of the device frame 1 and distributed on both sides of the rectangular opening 5-2, a stable rod 5-4 fixed between a pair of fixing blocks 5-3 located at both ends of the bottom of the device frame 1, a support plate 5-5 slidably and sleevably connected to the stable rod 5-4, the support plate 5-5 being attached to the inner side surface of the conveying belt 3, an adjusting screw 5-6 being rotatably connected between a pair of fixing blocks 5-3 located at the middle position of the bottom of the device frame 1, the support plate 5-5 being threadedly connected with the adjusting screw 5-6, an outer frame 5-7 being arranged on both sides of the device frame 1, a support stud 5-8 being threadedly connected in the outer frame 5-7, a pressure block 5-9 being rotatably connected to one end of the support stud 5-8, a pair of slide rods 5-10 being arranged on the surface of the pressure block 5-9 and slidably and sleevably connected to the outer frame 5-7.
[0040] In some examples, in the bolt polishing process, in order to effectively clamp the bolt and accurately deliver it to the polishing position, a clamping assembly 5 is designed, which includes a plurality of clamping grooves 5-1 evenly arranged on the surface of the conveying belt 3. These clamping grooves 5-1 are the key structure for directly clamping the bolt. Through the cooperation of the clamping grooves 5-1 and the bolt, the bolt can be stably clamped so that it will not slip or fall during the conveying process. A rectangular opening 5-2 is arranged on the surface of the equipment rack 1, and a plurality of fixing blocks 5-3 are arranged at the bottom of the equipment rack 1, distributed on both sides of the rectangular opening 5-2, and a stable rod 5-4 is fixed between a pair of opposite fixing blocks 5-3 at both ends of the bottom of the equipment rack 1. A support plate 5-5 is slidably connected on the stable rod 5-4, which is attached to the inner surface of the conveying belt 3, and plays a supporting and stabilizing role for the conveying belt 3, ensuring that the conveying belt 3 remains flat during operation, avoiding the influence of the deformation of the conveying belt 3 on the clamping and conveying effect of the bolt. A pair of fixing blocks 5-3 are arranged at the middle position of the bottom of the equipment rack 1, and an adjusting screw 5-6 is rotatably connected between them. The support plate 5-5 is connected with the adjusting screw 5-6 through thread cooperation. When the adjusting screw 5-6 is rotated, the support plate 5-5 can move along the direction of the stable rod 5-4, so that the distance between the clamping grooves 5-1 and the bolt can be adjusted according to different specifications of the bolt, so that the clamping grooves 5-1 and the bolt can be better matched and clamped. The outer frame 5-7 is arranged on both sides of the equipment rack 1, and the support stud 5-8 is connected through thread screwing. The pressure block 5-9 connected to one end of the support stud 5-8 can further apply pressure to the bolt on the conveying belt 3, which can increase the tension of the conveying belt 3. A pair of slide rods 5-10 are arranged on the surface of the pressure block 5-9, which are slidably connected in the outer frame 5-7, so that the pressure block 5-9 can remain stable during movement, ensuring that uniform pressure is applied to the bolt.
[0041] As shown in Figures 1-4 The polishing assembly 6 includes a fixed sleeve frame 6-1, which is arranged at the output end of the telescopic air cylinder 4. A cavity 6-2 is arranged in the fixed sleeve frame 6-1. A pressure rod 6-3 is movably connected in the cavity 6-2. A first spring 6-4 is connected between the upper end of the pressure rod 6-3 and the cavity 6-2. A rotating cover 6-5 is rotatably connected in the fixed sleeve frame 6-1. A plurality of pairs of second springs 6-6 are arranged on the inner surface of the rotating cover 6-5. A polishing plate 6-7 is connected to one end of a pair of second springs 6-6. A drive motor 6-8 is arranged on the upper surface of the fixed sleeve frame 6-1. A drive gear 6-9 is arranged at the output end of the drive motor 6-8. An external gear 6-10 is arranged on the side surface of the rotating cover 6-5. The drive gear 6-9 is engaged with the external gear 6-10.
[0042] In some examples, in the machining process of the hexagonal bolt, in order to effectively polish the top of the hexagonal bolt, a polishing assembly 6 is designed, which includes a fixed sleeve frame 6-1 arranged at the output end of the telescopic cylinder 4, the telescopic cylinder 4 can drive the fixed sleeve frame 6-1 to move up and down, a cavity 6-2 is opened in the inside of the fixed sleeve frame 6-1, which provides space for the movement of the pressure rod 6-3, the first spring 6-4 connected between the upper end of the pressure rod 6-3 and the cavity 6-2 enables the pressure rod 6-3 to move up and down elastically under the action of the first spring 6-4, when the fixed sleeve frame 6-1 covers the top of the bolt, the pressure rod 6-3 will be supported in the hexagonal groove of the top of the bolt, the elastic force generated by the first spring 6-4 exerts a certain pressure on the top of the bolt, ensuring the stability of the polishing process, the rotating cover 6-5 is rotatably connected in the inside of the fixed sleeve frame 6-1, a plurality of pairs of second springs 6-6 are arranged on the inner side surface of the rotating cover 6-5, each pair of second springs 6-6 has a polishing plate 6-7 connected at one end, the arrangement of the second spring 6-6 enables the polishing plate 6-7 to adaptively adjust according to the shape and size of the top of the bolt, ensuring that the polishing plate 6-7 is in full contact with the top of the bolt, improving the polishing effect, the lower end of the polishing plate 6-7 is outwardly bent, facilitating the sleeving of the bolt, the driving motor 6-8 is arranged on the upper surface of the fixed sleeve frame 6-1, the driving gear 6-9 at the output end of the driving motor 6-8 is engaged with the external gear 6-10 around the side surface of the rotating cover 6-5, when the driving motor 6-8 is started, the driving gear 6-9 drives the external gear 6-10 to rotate, thereby enabling the rotating cover 6-5 to rotate in the fixed sleeve frame 6-1, the rotating rotating cover 6-5 drives the polishing plate 6-7 to perform circular motion polishing operation on the top of the bolt.
[0043] For example, as shown in Figure 3 The device frame 1 is provided with a discharging hopper 7 at one end, and the inner bottom of the discharging hopper 7 is an inclined structure surface.
[0044] In some examples, by arranging the discharging hopper 7 with an inclined structure, the fallen bolts are easily dropped outward, and the placement container is easily received.
[0045] For example, as shown in Figure 1 The clamping groove 5-1 is an arc surface structure, and the internal depth of the clamping groove 5-1 is lower than the radius size of the bolt.
[0046] In some examples, by arranging the arc surface structure, the clamping groove 5-1 can closely fit the bolt, and can be matched with the installation of PLC controllers and other related devices, so that the clamping groove 5-1 is aligned with the axis position of the telescopic cylinder 4 every time the conveying belt 3 stops, ensuring accurate positioning, and a series of settings such as stop time can be set.
[0047] For example, as shown in Figure 1 The support plate 5-5 is in an L-shaped structure as a whole, and the top side end surface of the support plate 5-5 is lower than the surface of the conveying belt 3.
[0048] In some examples, the support plate 5-5 is bent to one side by the L-shaped structure, and the upper surface of the support plate 5-5 can support the edge of the bottom surface of the nut during the movement of the bolt, ensuring that the height of the bolt does not decrease during the movement. The thickness of the support plate 5-5 can be set according to the actual situation. In the figure, the actual use may deviate for the purpose of clear display effect. If the thickness of the support plate 5-5 is too high, it will rub against the polishing plate 6-7. Therefore, in actual use, the thickness of the support plate 5-5 is controlled to be the lowest, and there is no mutual influence between the support plate 5-5 and the polishing plate 6-7.
[0049] In actual use: according to the bolt specification, rotate the adjusting screw 5-6 to move the support plate 5-5 on the stable rod 5-4 to adjust the spacing of the conveying belt 3, put the bolt into the clamping groove 5-1, start the conveying belt 3, the bolt moves with the conveying belt 3, when it reaches the polishing position, the telescopic cylinder 4 pushes the polishing assembly 6 to descend, the pressure rod 6-3 is supported in the internal hexagonal groove of the bolt, then the driving motor 6-8 is started to drive the rotating cover 6-5 and the polishing plate 6-7 to rotate at high speed, the nut part is polished during the rotation, after the polishing is completed, the bolt moves with the conveying belt 3 to the discharge hopper 7, and slides outwards, a container can be placed in advance for collection.
[0050] It should be noted that the above examples are only used to illustrate the technical solutions of the present disclosure and are not limiting. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, and they should be covered in the scope of the claims of the present disclosure.
