DETAILED DESCRIPTION
[0026] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0027] Please refer to Figures 1-6 In the embodiments of the present application, the device comprises a supporting table 1, a moving device 2 and a clamping device 3.
[0028] The moving device 2 comprises a bottom plate 21, two ends of the bottom plate 21 are fixedly connected with vertical plates 22, a motor 23 is fixedly installed on one side of the vertical plate 22, an output shaft of the motor 23 is cooperatively connected with a lead screw 25, a sliding block 24 is cooperatively connected with the lead screw 25, and the other end of the lead screw 25 is rotatably connected with the vertical plate 22; guide sliding rods 26 are arranged on both sides of the lead screw 25, and the guide sliding rods 26 are fixedly connected with the vertical plate 22; the sliding rods 26 are slidably connected with the sliding block 24, and the clamping device 3 is arranged on the sliding block 24.
[0029] By adopting the above technical solution, the structure is installed in the middle of the two transmission lines and below the processing equipment, and the moving device 2 cooperates with the clamping device 3 to provide a basis for realizing double-belt alternating operation. The sliding block 24 can move under the action of the lead screw 25 and the guide sliding rods 26, so that the clamping device 3 can reciprocate between the two transmission lines and the processing position. When one side of the clamping head clamps the disc brake from one transmission line and moves to the processing position, the other side of the clamping head can clamp the disc brake on the other transmission line at the same time, so that the uninterrupted production process is realized, the idle time of the equipment is avoided, and the processing quantity of the disc brake per unit time is greatly improved.
[0030] Further, the motor 23 drives the lead screw 25 to rotate, the lead screw 25 drives the sliding block 24 to move, the guide sliding rods 26 are fixedly connected with the vertical plate 22 and are parallel to the lead screw 25, and can provide stable and accurate guidance for the sliding block 24, which ensures that the sliding block 24 drives the clamping device 3 to quickly and accurately reach the specified position, reduces the moving and positioning time, and further improves the production efficiency.
[0031] In the embodiments, the clamping device 3 comprises a moving plate 34, the moving plate 34 is bolted with the sliding block 24, and rotary clamping air cylinders 31 are fixedly connected with both ends of the moving plate 34, respectively; a clamping head 32 is arranged at the front end of each rotary clamping air cylinder 31, the clamping head 32 is slidably connected with the rotary clamping air cylinder 31, and a plurality of buffer pads 33 are bolted inside the clamping head 32.
[0032] By adopting the above technical scheme, the rotary clamping air cylinder 31 is powered by compressed air. When the compressed air enters the cylinder from the air inlet, a pressure difference is formed on one side of the piston, which pushes the piston to move linearly in the cylinder body. A rack is installed on the piston, and a gear meshing with the rack is installed on the rotating shaft. When the piston moves linearly, the rack drives the gear to rotate, thereby causing the rotating shaft to rotate. At the same time, the clamping jaw also realizes the clamping function. Usually, it is realized through mechanical linkage or special structural design. For example, some rotary clamping air cylinders use a connecting rod mechanism. When the rotating shaft rotates, the connecting rod drives the clamping jaw to open and close, thereby realizing the clamping and loosening of the disc brake.
[0033] Further, the multiple buffer pads 33 inside the chuck 32 are made of rubber material with high elasticity and wear resistance, and the surface is provided with anti-skid lines. When clamping the disc brake, the buffer pad 33 can buffer the pressure of the chuck 32 on the disc brake, avoiding direct damage to the surface of the disc brake by the chuck 32. The anti-skid lines increase the friction force, ensuring stable clamping of the disc brake during processing, preventing processing errors caused by displacement or shaking, and ensuring the stability and precision of processing.
[0034] In the embodiment, the support table 1 includes a table top 11, which is in sliding connection with the support table 1 and is bolted to the bottom plate 21. The table top 11 is provided with air cylinders 12 at both ends below, which are bolted to the support table 1. The piston rod of the air cylinder 12 is fixedly connected to the bottom of the table top 11.
[0035] By adopting the above technical scheme, the table top 11 is in sliding connection with the support table 1, and the air cylinders 12 at both ends below the table top 11 can adjust the height and position of the table top 11 through the extension and retraction of the piston rod. The height of the clamping device 3 can be adjusted according to the actual height of the transmission device, and the clamping device 3 can be adapted accordingly.
[0036] At the same time, the clamping device 3 can also be flexibly adjusted according to the production process requirements of different disc brakes, the height and position of different processing equipment, etc. For example, when cooperating with cutting and drilling equipment of different heights, the height of the table top 11 can be adjusted through the air cylinders 12 to ensure that the disc brake can accurately enter the processing position, thereby improving the adaptation ability of the equipment to different production scenes.
[0037] Further, the table top 11 is in sliding connection with the support table 1, and the table top 11 is bolted to the bottom plate 21. This connection method is convenient for disassembly and installation. When the equipment needs to be maintained, repaired or parts need to be replaced, the table top 11 can be easily separated from the support table 1 for inspection and repair of the moving device 2, the clamping device 3, etc., thereby reducing the equipment downtime and maintenance cost.
[0038] In the embodiment, the rotating clamping cylinder 31 has an angle adjusting function, and can accurately control the rotation angle of the chuck 32 within a range of 0-180°, thereby meeting the multi-angle machining requirements of the disc brake.
[0039] By adopting the above technical scheme, the disc brake needs different machining angles in different machining procedures such as drilling and milling during the production process. The rotating clamping cylinder 31 can accurately control the rotation angle of the chuck 32 within a range of 0-180°, so that the disc brake can be machined at the optimal angle. For example, the angle of the disc brake can be accurately adjusted according to the position and direction of milling during milling, thereby ensuring the milling accuracy, effectively improving the machining accuracy, reducing the waste rate caused by inaccurate angles, and ensuring the consistency of product quality.
[0040] In addition, the traditional chuck 32 cannot meet the multi-angle machining requirements for some disc brakes with special shapes or complex structures, but the rotating clamping cylinder 31 of the utility model can flexibly adjust the angle of the chuck 32, adapt to various complex machining requirements, widen the machining range of the product, and improve the production capacity of enterprises for different types of disc brakes.
[0041] In the embodiment, the buffer pad 33 is made of rubber material with high elasticity and wear resistance, and the surface of the buffer pad 33 is provided with anti-skid lines.
[0042] By adopting the above technical scheme, the disc brake may be relatively rubbed with the chuck 32 during the machining and movement of the disc brake. The buffer pad 33 made of rubber material has the wear resistance, can effectively reduce the wear of the surface of the disc brake caused by the friction, prolong the service life of the disc brake, and ensure the performance stability of the disc brake during subsequent use.
[0043] In addition, the surface of the buffer pad 33 is provided with anti-skid lines, thereby effectively increasing the friction between the chuck 32 and the disc brake. During the machining of the disc brake, especially during the procedures such as drilling and milling that may generate a large acting force, the anti-skid lines can prevent the disc brake from sliding or moving in the chuck 32, thereby ensuring the position accuracy of the disc brake during the machining process, and improving the machining quality and the consistency of the product.
[0044] In the embodiment, the number of the guide sliding rods 26 is not less than two, and the guide sliding rods 26 are arranged in parallel with the screw rod 25 to provide stable and accurate guidance for the sliding block 24.
[0045] By adopting the technical scheme, the guide sliding rods 26 are arranged in parallel with the screw rod 25, and the force borne by the sliding block 24 can be dispersed during movement of the sliding block 24; when the screw rod 25 drives the sliding block 24, if there is only one guide sliding rod, the sliding block 24 may shake or tilt due to uneven force; the arrangement of the plurality of guide sliding rods 26 enables the sliding block 24 to be stably supported in all directions, ensures smooth movement of the sliding block 24 along a predetermined track, and avoids inaccurate positioning of the chuck due to shaking of the sliding block 24, thereby affecting clamping and machining of the disc brake.
[0046] In the embodiment, the support table 1 is fixedly connected with the baffle 13 on the two sides of the inner wall of the support table 1, and the height of the baffle 13 is lower than that of the support table 1.
[0047] By adopting the technical scheme, when the table top 11 is lowered under the action of the air cylinder 12, the baffle 13 can play a blocking role and effectively limit the downward stroke of the table top, which can avoid excessive lowering of the table top and collision or extrusion with other components in the support table 1, prevent damage of the equipment due to excessive lowering of the table top, protect the mechanical structure and electrical system of the equipment, and prolong the service life of the equipment.
[0048] The working principle of the utility model is as follows: firstly, the structure is installed at the middle of two transmission lines and below the machining device; at this time, the support table 1 is in an initial state, and the height and position of the table top 11 are adjusted by the air cylinder 12 below according to production requirements.
[0049] Then, the moving device 2 starts to work, the motor 23 on the one side of the vertical plate 22 is started, the output shaft of the motor 23 drives the screw rod 25 to rotate, the sliding block 24 on the screw rod 25 moves along the axial direction of the screw rod 25 under the rotation of the screw rod 25, the guide sliding rods 26 on the two sides of the screw rod 25 are fixedly connected with the vertical plate 22 and are in sliding connection with the sliding block 24, the guide sliding rods 26 provide stable and accurate guidance for the sliding block 24, so that the sliding block 24 can smoothly drive the clamping device 3 on it to move.
[0050] When the sliding block 24 drives the clamping device 3 to move above the transmission device, the clamping device 3 starts to work, the rotary clamping air cylinder 31 at the two ends of the moving plate 34 drives the chuck 32 to clamp the disc brake, and the buffer pad 33 inside the chuck 32 can effectively buffer the pressure of the chuck 32 on the disc brake, so as to avoid damage to the surface of the disc brake, and the anti-skid lines increase the friction force, so as to ensure that the disc brake is stably clamped.
[0051] When one of the chucks 32 clamps the disc brake on one of the transmission lines, the motor 23 is started again, and the disc brake is transported to the machining position by the screw rod 25 and the sliding block 24, and at the same time, the other chuck 32 synchronously clamps the disc brake on the other transmission device.
[0052] After reaching the processing position, the rotary clamping cylinder 31 plays its angle adjustment function, according to the different processing requirements of the disc brake, such as drilling, milling and other processes, the rotary clamping cylinder 31 can accurately control the rotation angle of the chuck 32 within the range of 0-180°, so that the disc brake is processed at the best angle, and the processing precision and the consistency of product quality are improved; when the first disc brake is processed, the motor 23 drives the screw 25 to make the slider 24 drive the chuck 32 to make reciprocating motion and return, at this time, the chuck 32 on the other side which has clamped the new disc brake will move to the processing position under the action of the motor 23 and the screw 25, and a new round of processing will begin, so the cycle is repeated, and the uninterrupted working mode is realized, and the processing efficiency of the disc brake is effectively improved.
