DETAILED DESCRIPTION

[0022] refer to Figure 1 , 2, 3, 4, 5 and 9, describe in detail an embodiment of transporting a rough blank of a protective shell of a servo tester for grinding: a processing system for a protective shell of a servo tester, comprising a frame 11, the frame 11 is used for fixing and supporting, two pairs of screw rods Ⅰ41 are rotatably connected to the frame 11, each pair of screw rods Ⅰ41 is connected to a transport rack 42, each of the transport racks 42 is provided with a screw rod sleeve that drives the corresponding screw rod Ⅰ41, each screw rod Ⅰ41 is fixedly connected to the output shaft of the reduction motor Ⅰ, and the reduction motor Ⅰ is fixedly connected to the frame 11, each transport rack 42 is fixedly connected to a plurality of cylinders Ⅳ54, each transport rack 42 is provided with a clamping plate 43 fixedly connected to the cylinder rod of the corresponding cylinder Ⅳ54, and the rough blank of the protective shell of the servo tester is placed at the lower end. On the clamping plate 43, multiple cylinders IV54 are started, and the cylinder rods of the multiple cylinders IV54 drive the two clamping plates 43 to move. The two clamping plates 43 correspond to each other up and down to achieve clamping of the rough blank of the protective shell of the servo tester during movement. Multiple reduction motors I are started, and the multiple reduction motors I drive the multiple screw rods I41 to rotate. The multiple screw rods I41 rotate and the corresponding screw rod sleeves drive the transport frame 42 to move. The two transport frames 42 drive the two clamping plates 43 to move through the multiple cylinders IV54, thereby realizing the transportation of the rough blank of the protective shell of the servo tester. At the same time, starting the corresponding extension and retraction of the multiple cylinders IV54 can drive the two clamping plates 43 to rise and fall, thereby realizing the movement of the rough blank of the protective shell of the servo tester in the vertical direction. The clamping plate 43 is provided with multiple protrusions 44. The friction between the clamping plate 43 and the rough blank of the protective shell of the servo gear tester is increased by multiple protrusions 44 to ensure stable transportation of the rough blank of the protective shell of the servo gear tester. The protrusions 44 are all made of flexible materials, such as rubber or a synthetic material of rubber, which can deform when clamping the rough blank of the protective shell of the servo gear tester to increase the contact area, thereby ensuring the stability of transportation of the rough blank of the protective shell of the servo gear tester. Two positioning bars for positioning the rough blank of the protective shell of the servo gear tester can be fixedly connected to the lower clamping plate 43, so as to realize the positioning of the rough blank of the protective shell of the servo gear tester. A fixed frame 13 is fixedly connected to one side of the frame 11, and the fixed frame 13 is correspondingly provided with two limit plates 16 slidably connected to the frame 11. The two limit plates 16 are fixedly connected to the movable frame 15, and the fixed frame 13 and the movable frame 15 are rotatably connected to the grinding rods 21. The two grinding rods 21 can rotate around their own axes. When the rough blank of the servo tester protective shell moves along the axis of the screw rod Ⅰ41, the rough blank of the servo tester protective shell is polished by the two rotating grinding rods 21. The rough blank of the servo tester protective shell is formed with spaced raised strips. The grinding rods 21 are linearly evenly distributed with multiple rotary grooves. The rotary grooves are used to grind the raised strips on the rough blank of the servo tester protective shell, so that the rough blank of the servo tester protective shell can be fully polished, which is convenient for the subsequent spraying of the protective shell. The frame 11 is fixedly connected to the cylinder Ⅱ52 that drives the movable frame 15 to slide.Start cylinder II 52, which drives the movable frame 15 to slide, thereby realizing the sliding of the movable frame 15, and further realizing the sliding of the grinding rod 21, and can adjust the clamping of the two grinding rods 21 for grinding flatness, can adjust the feeding degree of grinding, and can perform different degrees of adjustment.

[0023] refer to Figure 4 , 7 8, a detailed description of an embodiment of cutting the grooves between the raised strips on the rough blank of the protective shell of the servo tester is provided: a cutting frame 31 is slidably connected to one side of the limit plate 16 installed on the frame 11, and a plurality of cutting frames 32 are detachably connected to the cutting frame 31, and the cutting frame 32 is fixed by bolts passing through the through holes processed on the cutting frame 32 and connected with the threaded holes processed on the cutting frame 31, and the cutting frame 32 can be disassembled by removing the bolts, and each cutting frame 32 is detachably connected to a cutting knife 33, and the plurality of cutting knives 33 respectively correspond to the protrusions between the plurality of rotary grooves, so that when the rough blank of the protective shell of the servo tester is transported, the cutting knife 33 can be used to realize the cutting. The grooves between the raised strips on the rough blank of the protective shell of the steering gear tester are cut, and then the outer wall of one side of the rough blank of the protective shell of the steering gear tester is fully polished by two rotating polishing rods 21. When there is no raised plane when polishing the rough blank of the protective shell of the steering gear tester, the plane is polished by the position of the unprocessed rotary grooves of the two polishing rods 21. The rough blank of the protective shell of the steering gear tester is clamped by two clamping plates 43 to move in the vertical direction, ensuring that the two polishing rods 21 can fully polish the plane and prevent the occurrence of grinding dead corners due to the rotary grooves on the two polishing rods 21. The frame 11 is fixedly connected with a cylinder III53 that drives the cutting frame 31 to slide. When cylinder III53 is started, cylinder III53 drives the cutting frame 31 to slide, and the cutting frame 31 drives the multiple cutting frames 32 to move, thereby driving the multiple cutting knives 33 to slide, thereby realizing the feeding of the cutting depth of the multiple cutting knives 33, cooperating with the reciprocating motion of the rough blank of the servo tester protective shell, and cutting the rough blank of the servo tester protective shell is performed multiple times.

[0024] refer to Figure 3 , 5 6, detailed description of the first embodiment of driving the two grinding rods 21 to rotate: the two grinding rods 21 are respectively fixedly connected to the output shafts of the two reduction motors II, the reduction motors II are fixedly connected to the corresponding fixed frame 13 and the movable frame 15, the two reduction motors II are started, and the two reduction motors II drive the two grinding rods 21 to rotate, thereby realizing the grinding of the rough blank of the protective shell of the servo tester by the rotation of the two grinding rods 21.

[0025] refer to Figure 3 , 5and 6, detailing the second embodiment of driving the two grinding rods 21 to rotate: adopting the above-mentioned method of driving the grinding rods 21 to rotate, the wires of the reduction motor II fixedly connected to the fixed frame 13 are not convenient for routing and when grinding the rough blank of the protective shell of the servo tester, it is not conducive to the heat dissipation of the reduction motor II fixedly connected to the fixed frame 13. Therefore, a driving frame 12 is fixedly connected to the frame 11, and a driving shaft 24 is rotatably connected to the driving frame 12. Both ends of each grinding rod 21 are fixedly connected to a driven wheel 22, and the driving shaft 24 and the corresponding driven wheel 22 are driven by a toothed belt 23. The driving frame 12 is fixedly connected with a plurality of cylinders Ⅰ51, and the cylinder rods of at least two cylinders Ⅰ51 are fixedly connected with an adjusting frame 14, and a tensioning shaft 17 with a tensioning toothed belt 23 is rotatably connected to the adjusting frame 14. The driving shaft 24 is fixedly connected to the output shaft of the reduction motor III. When the reduction motor III is started, the reduction motor III drives the driving shaft 24 to rotate, and the driving shaft 24 drives the corresponding driven wheel 22 to rotate through the toothed belt 23, and the driven wheel 22 drives the two grinding sticks 21 to rotate, so as to realize the test of the steering gear. The rough blank of the instrument protective shell is polished, and when the driving frame 15 is driven to slide, the grinding rod 21 on the moving frame 15 moves and drives the two corresponding driven wheels 22 to move. At this time, the cylinder Ⅰ51 is started to drive the adjusting frame 14 to move, and the adjusting frame 14 drives the tensioning shaft 17 to move, thereby realizing the tightening of the transmission toothed belt 23, ensuring the stable power transmission of the toothed belt 23, ensuring the heat dissipation of the power source that drives the two grinding rods 21 to rotate and the arrangement of the wires, and ensuring the continuous processing of the rough blank of the servo tester protective shell.
