Description

Technical Field

[0001] The present application relates to the technical field of piston rod processing equipment, and more specifically, to a fixing device for cutting a piston rod. Background Art

[0002] The piston rod is a mechanical component that converts the reciprocating linear motion of the piston into rotational motion or other forms of motion or force output. The piston rod needs to undergo heat treatment, cutting, grinding and other processes during the production process. When cutting the piston rod, the piston rod needs to be fixed in position to avoid displacement of the piston rod when being cut. Therefore, the fixing device for piston rod cutting is also an indispensable equipment in the piston rod processing process.

[0003] However, most of the existing piston rod cutting fixing devices on the market cannot clamp and fix piston rods of different diameters. Therefore, when piston rods of different diameters need to be cut, fixing devices of different specifications need to be used, which reduces the practicality of the device. Utility Model Content

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] The present application embodiment discloses a fixing device for cutting a piston rod. Figure 1-4 , including a base 1, the top of the base 1 is fixedly connected to a cylinder 2, the telescopic end of the cylinder 2 is fixedly connected to a lifting block 3, one end of the lifting block 3 is fixedly connected to a clamping frame 4, the inner wall of the clamping frame 4 is fixedly connected to a connecting plate 5, the top of the clamping frame 4 is slidably sleeved with a positioning rod 7, the top of the positioning rod 7 is fixedly connected to a limiting plate 8, the bottom of the limiting plate 8 is fixedly connected to a spring 9, and the front of the clamping frame 4 is provided with a groove 16.

[0032] A bearing 12 is inlaid on the top of the clamping frame 4, and a support frame 10 is fixedly connected to the top of the clamping frame 4. A motor 11 is fixedly connected to the inner wall of the support frame 10, and a driving shaft of the motor 11 is fixedly connected to a first bevel gear 13 through a coupling. A moving block 18 is slidably connected to the inner wall of the groove 16, and a fixed plate 19 is fixedly connected to one end of the moving block 18. When the positioning rod 7 tightly clamps the outer wall of the piston rod, the motor 11 drives the fixed plate 19 to tightly fix the positioning rod 7. Since there are multiple positioning rods 7, multiple positioning rods 7 can fix outer walls of different diameters, so that the device can clamp and fix piston rods of different diameters, and then when piston rods of different diameters need to be cut, there is no need to replace the equipment, thereby improving the practicality of the device.

[0033] In this embodiment, the clamping frame 4 is shaped like an inverted "U" structure, and a non-slip pad 6 is fixedly connected to one side of the connecting plate 5. The cylinder 2 drives the clamping frame 4 to reset, and then multiple positioning rods 7 will fit onto the outer wall of the piston rod.

[0034] In this embodiment, the spring 9 is slidably sleeved with the positioning rod 7 , and the bottom of the spring 9 is fixedly connected to the top of the clamping frame 4 . When the piston rod is not fixed, the clamping frame 4 will be reset by the spring 9 .

[0035] In this embodiment, the driving shaft of the motor 11 is fixedly sleeved with the inner ring of the bearing 12, the inner wall of the groove 16 is fixedly connected with the threaded rod 14, and the outer wall of the threaded rod 14 is fixedly sleeved with the second bevel gear 15. Starting the motor 11 can drive the first bevel gear 13 to rotate.

[0036] In this embodiment, the second bevel gear 15 is meshedly connected with the first bevel gear 13 , and the moving block 18 is threadedly sleeved with the threaded rod 14 , so that the threaded rod 14 can be driven to rotate by the second bevel gear 15 .

[0037] In this embodiment, a channel 17 is formed on the inner wall of the groove 16 , and a moving block 18 is slidably connected to the channel 17 , so that the moving block 18 can drive the fixing plate 19 to move toward the limiting plate 8 .

[0038] The implementation principle of the fixing device for cutting a piston rod in the embodiment of the present application is as follows: first, the cylinder 2 is started to drive the lifting block 3 and the clamping frame 4 to move upward, and then the piston rod can be placed on the base 1 and located below the positioning rod 7. Then, the cylinder 2 drives the clamping frame 4 to reset. When the positioning rod 7 is blocked by the outer wall of the piston rod, the spring 9 will be in a stretched state, and then the multiple positioning rods 7 will fit on the outer wall of the piston rod. The elastic force of the spring 9 enables the positioning rod 7 to tightly clamp the outer wall of the piston rod;

[0039] Secondly, the starting motor 11 drives the first bevel gear 13 to rotate, and then the threaded rod 14 can be driven to rotate through the second bevel gear 15, and then the fixed plate 19 can be driven to move toward the limit plate 8 through the moving block 18, and then the fixed plate 19 will tightly fix the positioning rod 7, and the position of the positioning rod 7 will not change automatically, so that the piston rod is tightly fixed;

[0040] Finally, since there are multiple positioning rods 7, multiple positioning rods 7 can fix outer walls of different diameters, so that the device can clamp and fix piston rods of different diameters.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
