Description

Technical Field

[0001] The invention relates to the technical field of oil cylinder inner wall detection, and in particular to an oil cylinder inner wall smoothness detection device. Background Art

[0002] The oil cylinder is a commonly used component in the hydraulic system. There is a piston rod inside the oil cylinder to convert hydraulic energy into mechanical energy. If the inner wall of the oil cylinder is not smooth enough, the friction will increase during use, causing the inner wall of the oil cylinder or the piston to wear, affecting the performance of the product. Therefore, a cylinder inner wall smoothness detection device is needed to detect it.

[0003] The existing oil cylinder inner wall detection device usually uses a displacement device to push the detection head forward to realize the detection of the oil cylinder inner wall. Through the above method, it is impossible to realize the full range of detection of the inside of the oil cylinder.

[0004] In view of the above problems, we propose a device for detecting the smoothness of the inner wall of an oil cylinder. Summary of the invention

[0048] The present invention is based on Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The intermittent switch mechanism 16 includes a sliding block mechanism 21 and a baffle 22.

[0049] The present invention is based on Figure 7 , Figure 8 The sliding block mechanism 21 includes a collar plate 23, a guide rail 24, a guide rail block 25, a spring 26, and a toggle rod 27.

The gravity of one group of guide rail blocks 25 is greater than the gravity of the other group of guide rail blocks. When the baffle plate 22 is at the lower end of the rotating shaft 14, the group with greater gravity can pass through the rod groove 29, and the group with less gravity cannot pass through the rod groove 29. When the baffle plate 22 is at the upper end of the rotating shaft 14, the group with greater gravity cannot pass through the rod groove 29, and the group with less gravity can pass through the rod groove 29.

[0050] The present invention is based on Figure 3 , Figure 5 , Fig. 9The intermittent translation mechanism 7 includes a threaded rod 30, an intermittent rotary switch mechanism 31, and a rotating shaft rod 32.

[0051] The present invention is based on Figure 3 , Fig. 9 , Fig.10 , Fig.11 The intermittent rotary switch mechanism 2 31 includes a sliding block mechanism 2 33 and a baffle mechanism 34. The sliding block mechanism 2 33 is fixed to the rotating shaft 32, and two groups are symmetrically arranged with the center position of the rotating shaft 32 as a reference; through the coordinated use of the sliding block mechanism 2 33 and the baffle 2 36, the intermittent translation of the detection head mechanism 6 is realized.

[0052] according to Fig. 9 , Fig.10 , Fig.11 The baffle mechanism 34 includes a circular support plate 35 and a second baffle 36 . The circular support plate 35 is fixedly connected to the threaded rod 30 , and the second baffle 36 is fixedly connected to the circular support plate 35 , and is used in conjunction with the two sets of the second sliding block mechanisms 33 .

The collar plate 237 is fixedly sleeved on the rotating shaft 32. The guide rail 238 is fixedly connected to the collar plate 237 through a connecting rod. The guide rail block 239 is slidably arranged on the guide rail 238. The toggle rod 241 is fixedly connected to the end surface of the guide rail block 239 close to the circular support plate 35 and is used in conjunction with the baffle 236.

There is a support plate 42 fixedly connected to the guide bar 38; the baffle plate 36 is provided with a rod groove 43 for the passage of the toggle rod 41, and the gravity of one group of guide blocks 39 is greater than the gravity of the other group of guide blocks 39. When the baffle plate 36 is at the lower end of the rotating shaft 32, the group with greater gravity can pass through the rod groove 43, and the group with less gravity cannot pass through the rod groove 43. When the baffle plate 36 is at the upper end of the rotating shaft 32, the group with greater gravity cannot pass through the rod groove 43, and the group with less gravity can pass through the rod groove 43.

[0054] The present invention is based on Figure 3 , Fig.12 The pulley mechanism 8 includes a pulley 44 and a connecting belt 45. Two pulleys 44 are provided, which are coaxially fixed on the rotating shaft 14 and the rotating shaft 32 respectively. The two pulleys 44 are connected by a connecting belt 45. The pulley mechanism 8 can make the rotating shaft 14 drive the rotating shaft 32 to rotate.

[0055] The present invention is based on Figure 1 , Figure 5 , Fig.13 The cylinder tube fixing mechanism 2 includes a supporting guide rail block 46, a clamping hand 47, and an electric telescopic rod 48. The supporting guide rail block 46 is fixedly connected to the machine platform 1 and is vertically arranged on one side of the guide rail 17. The clamping hand 47 is provided with two groups and is symmetrically slidably arranged on the supporting guide rail block 46. The electric telescopic rod 48 is fixedly connected to the supporting guide rail block 46 and its output end is fixedly connected to the clamping hand 47. When the electric telescopic rod 48 is started, it drives the clamping hand 47 to slide, and the cylinder is clamped and fixed by the two groups of clamping hands 47.

[0056] according to Figure 8 , Fig.11 The two first guide rails 24 and the two second guide rails 38 are evenly spaced apart.

[0057] Principle of the present invention: When in use, the driving motor 13 is started, driving the rotating shaft 14 to rotate, driving the rotating shaft rod 32 to rotate through the pulley mechanism 8, and then driving the ring plate 2 37 to rotate, and then driving the guide rail 2 38 to rotate. At this time, the baffle plate 2 36 is at the upper end of the rotating shaft rod 32, and the toggle rod 2 41 is in contact with the baffle plate 2 36. The toggle rod 2 41 pushes the baffle plate 2 36 to rotate around the rotating shaft rod 32, driving the circular support plate 35 and the threaded rod 30 to rotate. Under the action of the support plate 4 threadedly connected to the threaded rod 30, the support frame 12 slidably connected to the machine table 1 slides forward, thereby causing the intermittent rotating mechanism 5 to move forward, causing the detection head 11 therein to move forward, thereby increasing its detection range. When the baffle plate 236 rotates to the lower end of the rotating shaft 32, under the action of the gravity of the guide block 239, the toggle rod 241 moves downward and passes through the rod slot 243 of the baffle plate 236, and will not continue to push the baffle plate 236 to rotate until the other group of toggle rods 241 rotates to the bottom of the rotating shaft 32. Since the gravity of the guide block 239 in this group is smaller than that of the other group of guide block 239, when it is below the rotating shaft 32, under the action of the pulling force of the spring 240, it will not pass through the rod slot 243, thereby driving the baffle plate 236 and the threaded rod 30 to rotate. In the above two processes, the intermittent movement of the intermittent rotating mechanism 5 is realized, and the intermittent movement of the detection head 11 is realized.

[0058] Another state description, when the shaft 14 rotates, it drives the collar plate 23 to rotate, and then drives the guide rail 24 to rotate. At this time, the baffle 22 is at the upper end of the shaft 14, and the toggle rod 27 contacts the baffle 22. The toggle rod 27 pushes the baffle 22 to rotate around the shaft 14, driving the friction disk 18 to rotate, so that the detection head 11 rotates. When the baffle 22 rotates to the lower end of the shaft 14, under the action of the gravity of the guide rail block 25, the toggle rod The guide rail block 25 in this group has a small gravity. When it is below the rotating shaft 14, it will not pass through the rod slot 29 under the pulling force of the spring 26, and thus will drive the detection head 11 to rotate. In the above two processes, the intermittent rotation of the detection head 11 is realized.

[0059] The first collar plate 23 and the second collar plate 37 rotate alternately.

[0060] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
