Description
Technical Field
[0001] This utility model relates to the technical field of piston rod processing devices, specifically a piston rod processing device. Background Technology
[0002] Piston rod turning is an important step in piston rod machining. Piston rod turning is a process of cutting the piston rod on a lathe, mainly used for forming external diameters, threads, and other structures. First, the piston rod is fixed on a tool holder, and then roughing and finishing are performed. Roughing is mainly to remove excess material and ensure dimensional accuracy, while finishing is mainly to ensure surface flatness and roughness, meeting design requirements.
[0003] Currently, in existing technologies, piston rods require a fixture to hold and fix them during turning. Conventional fixtures are used in the machining process of existing piston rods. However, since different models of piston rods have different diameters, conventional fixtures cannot accommodate piston rods of different diameters. Therefore, there is a need to propose a piston rod machining device. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, such as the inability of existing clamping fixtures for piston rod processing to adapt to piston rods of different diameters, this utility model proposes a piston rod processing device.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a piston rod processing device, including a base, a support frame fixedly connected to one side of the top of the base, a clamping mechanism provided on the other side of the top of the base, a motor provided on one side of the support frame, and a chuck fixedly connected to the output end of the motor; The clamping mechanism includes a fixed frame, which is fixedly connected to the top of the base. A lower clamp is fixedly connected to the top of the fixed frame, and an upper clamp is rotatably connected to the top of the lower clamp. A first telescopic rod is threadedly connected to the top of the upper clamp. Sliding sleeves are slidably connected to both sides of the lower clamp. A second telescopic rod is slidably connected to the inner cavity of the sliding sleeve. A second threaded sleeve is rotatably connected to one end of the sliding sleeve. The second telescopic rod is threadedly connected to the inner cavity of the second threaded sleeve. An adjusting screw is rotatably connected to the inner cavity of the lower clamp, and the adjusting screw slides in cooperation with the sliding sleeve.
[0006] Preferably, the top of the upper clamp is rotatably connected to a first threaded sleeve, and the first telescopic rod is threadedly connected to the inner cavity of the first threaded sleeve.
[0007] Preferably, the lower clamp has grooves on both sides, and the sliding sleeve is slidably connected to the inner cavity of the groove.
[0008] Preferably, guide rods are fixedly connected to both sides of the outer wall of the sliding sleeve, and the guide rods are in contact with the surface of the lower clamp.
[0009] Preferably, one end of the sliding sleeve is fixedly connected to a fixing ring, and the lower edge of the second threaded sleeve is rotatably connected to the outside of the fixing ring.
[0010] Preferably, the inner cavity of the threaded sleeve is provided with a positioning groove, and a positioning rod is fixedly connected to the outer wall of the second telescopic rod, the positioning rod sliding in cooperation with the positioning groove.
[0011] Preferably, the adjusting screw is threadedly connected to an adjusting threaded sleeve on its outer wall, and a connecting rod is rotatably connected to both sides of the outer wall of the adjusting threaded sleeve, with one end of the connecting rod rotatably connected to the outer wall of the sliding sleeve.
[0012] The advantages of this utility model are: This invention fixes one end of the piston rod to the inner cavity of the chuck and places the other end in the inner cavity of the lower clamp. The end of the second telescopic rod abuts against the outer wall of the piston rod. Then, the upper clamp is rotated and locked. The end of the first telescopic rod is adjusted to abut against the outer wall of the piston rod, so that the piston rod can be stably clamped. By rotating the adjusting screw, the sliding sleeve is driven to slide, so that the relative sliding distance of the two second telescopic rods is adjusted. This allows the clamping angle between the two second telescopic rods to adapt to piston rods of different diameters, thereby achieving the effect of stably clamping piston rods of different diameters. This solves the problem that existing piston rod clamping fixtures cannot adapt to piston rods of different diameters. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a piston rod processing apparatus. (Refer to...) Figures 1-5 A piston rod processing device includes a base 1, a support frame 2 fixedly connected to one side of the top of the base 1, and a clamping mechanism 3 provided on the other side of the top of the base 1. A motor 21 is provided on one side of the support frame 2, and a chuck 22 is fixedly connected to the output end of the motor 21. By fixing one end of the piston rod in the inner cavity of the chuck 22 and clamping the other end of the piston rod in the inner cavity of the clamping mechanism 3, the motor 21 on the support frame 2 drives the chuck 22 to rotate, so that the chuck 22 drives the piston rod to rotate, thereby enabling the piston rod to be stably machined. The clamping mechanism 3 can adjust the clamping angle of the piston rod, thereby achieving the purpose of the clamping mechanism 3 to stably clamp piston rods of different diameters. The clamping mechanism 3 includes a fixed frame 31, which is fixedly connected to the top of the base 1. A lower clamp 32 is fixedly connected to the top of the fixed frame 31, and an upper clamp 33 is rotatably connected to the top of the lower clamp 32. A first telescopic rod 34 is threadedly connected to the top of the upper clamp 33. Sliding sleeves 37 are slidably connected to both sides of the lower clamp 32. A second telescopic rod 38 is slidably connected to the inner cavity of the sliding sleeve 37. A second threaded sleeve 39 is rotatably connected to one end of the sliding sleeve 37. The second telescopic rod 38 is threadedly connected to the inner cavity of the second threaded sleeve 39. An adjusting screw 311 is rotatably connected to the inner cavity of the lower clamp 32. The adjusting screw 311 slides in cooperation with the sliding sleeve 37. The piston rod is held in the inner cavity of the lower clamp 32. The second telescopic rod 38, in conjunction with the second threaded sleeve 39, can stably abut against the outer wall of the piston rod. Rotating the adjusting screw 311 causes it to rotate stably within the inner cavity of the fixed frame 31. The adjusting screw 311 drives the sliding sleeves 37 on both sides to slide relative to each other, thereby adjusting the clamping angle of the two second telescopic rods 38. This allows the two second telescopic rods 38 to clamp piston rods of different diameters. Rotating the upper clamp 33 and locking it in conjunction with the lower clamp 32, and using the first telescopic rod 34 to lock the upper surface of the piston rod, ensures that the piston rod can be stably clamped.
[0018] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The upper clamp 33 is rotatably connected to the top of a first threaded sleeve 35, and a first telescopic rod 34 is threaded into the inner cavity of the first threaded sleeve 35. The lower clamp 32 has sliding grooves 36 on both sides, and a sliding sleeve 37 is slidably connected to the inner cavity of the sliding groove 36. Guide rods 316 are fixedly connected to both sides of the outer wall of the sliding sleeve 37, and the guide rods 316 are in contact with the surface of the lower clamp 32. An adjusting threaded sleeve 312 is threadedly connected to the outer wall of the adjusting screw 311, and connecting rods 310 are rotatably connected to both sides of the outer wall of the adjusting threaded sleeve 312. One end of the connecting rod 310 is rotatably connected to the sliding sleeve. The outer wall of 37 is adjusted by rotating the adjusting screw 311, which drives the adjusting threaded sleeve 312 to slide. The adjusting threaded sleeve 312 drives the sliding sleeve 37 to slide in the sliding groove 36 through the connecting rod 310. The sliding sleeve 37, in conjunction with the guide rod 316 of the outer wall, slides stably against the surface of the lower clamp 32, thereby allowing the two second telescopic rods 38 to adjust the clamping angle. By rotating the first threaded sleeve 35, the first threaded sleeve 35 drives the first telescopic rod 34 to slide, thereby allowing the first telescopic rod 34 to press down against the upper surface of the piston rod.
[0019] Reference Figure 3 and Figure 4One end of the sliding sleeve 37 is fixedly connected to a fixing ring 313. The lower edge of the second threaded sleeve 39 is rotatably connected to the outside of the fixing ring 313. The inner cavity of the threaded sleeve is provided with a positioning groove 314. The outer wall of the second telescopic rod 38 is fixedly connected to a positioning rod 315. The positioning rod 315 slides in cooperation with the positioning groove 314. By rotating the second threaded sleeve 39, the second threaded sleeve 39 rotates on the outer wall of the fixing ring 313 and drives the second telescopic rod 38 to slide. The second telescopic rod 38 extends and retracts in the inner cavity of the sliding sleeve 37 and slides stably in cooperation with the positioning groove 314 and the positioning rod 315. This allows the extension and retraction distance of the second telescopic rod 38 to be adjusted, thereby further improving the adaptability of the two second telescopic rods 38 to clamp piston rods of different diameters.
[0020] Working principle: In use, one end of the piston rod is fixed in the inner cavity of the chuck 22, and the other end of the piston rod is stably clamped by the clamping mechanism 3 on one side of the base 1. The motor 21 on the support frame 2 drives the chuck 22 to rotate, thereby causing the chuck 22 to drive the piston rod to rotate and cooperate with the turning. The piston rod is clamped on the lower fixture 32, and the end of the second telescopic rod 38 abuts against the outer wall of the piston rod. The second threaded sleeve 39 is rotated, and the second threaded sleeve 39 cooperates with the fixing ring 313 to rotate stably and drive the second telescopic rod 38 to extend and retract within the sliding sleeve 37. The second telescopic rod 38 cooperates with the positioning groove 314 and the positioning rod 315 to slide stably, so that the second telescopic rod 38 can be extended and retracted to improve the fit of the piston rod. The adjustment screw 311 rotates stably within the cavity of the fixed frame 31, driving the adjusting threaded sleeve 312 to slide. The sliding of the adjusting threaded sleeve 312, through the connecting rod 310, causes the sliding sleeve 37 to slide within the sliding groove 36. The sliding sleeve 37, in conjunction with the guide rod 316, slides stably against the surface of the lower clamp 32, thereby allowing the two second telescopic rods 38 to adjust the clamping angle to accommodate piston rods of different diameters. The upper clamp 33 is rotated and locked onto the lower clamp 32. The rotation of the first threaded sleeve 35 drives the first telescopic rod 34 to press against the upper surface of the piston rod, thus stably clamping the piston rod and achieving the purpose of stably clamping piston rods of different diameters.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
