Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, specifically to an auxiliary positioning device for cutting mechanical parts. Background Technology

[0002] Mechanical components are the basic units that make up machinery and machines, including parts and components. A part is an indivisible individual component, while a component is composed of multiple parts that perform a specific function. Mechanical components can be classified in various ways. By material, they can be divided into metals (e.g., bolts, gears) and non-metals (e.g., plastics, rubber); by function, they can be divided into transmission (e.g., gears, chains), lubrication (e.g., oil pumps), hydraulics (e.g., hydraulic valves), sealing (e.g., O-rings), connection (e.g., flanges), fastening (e.g., bolts), bearings (e.g., ball bearings), springs (e.g., coil springs), etc. Furthermore, they can be classified by standardization level (e.g., special-purpose parts, general-purpose parts, standard parts), or by industry attribute (e.g., mechanical components, electronic components, etc.).

[0003] Metal pipes are one of the main materials for mechanical parts. When cutting metal pipes, it is common practice to manually draw auxiliary lines on the surface of the pipe to facilitate subsequent cutting. However, manual drawing relies on the operator's skills, experience, and eyesight, making it difficult to ensure that the position, angle, and length of the lines are completely consistent each time. Even experienced workers may experience deviations in the lines due to fatigue, distraction, or misjudgment, which will be directly transmitted to the cutting process, resulting in inaccurate pipe cutting dimensions, angle deviations, or uneven cuts. Therefore, an auxiliary positioning device for cutting mechanical parts is proposed to solve the above-mentioned problems. Utility Model Content

[0023] In the embodiments, by Figure 1-5 Provided is an auxiliary positioning device for cutting mechanical parts, comprising a frame 1, on which an inclined material support base plate 2 is fixedly mounted, a side plate 3 fixedly mounted on the frame 1 abutting against the material support base plate 2, and a movable plate 4 slidably connected to the frame 1 at the other end. A feeding assembly 5 for conveying metal pipes one by one is provided on the frame 1, located on the side with the lower height of the material support base plate 2. A processing table 6 is provided on one side of the frame 1, and a material separating component 7 is provided on the processing table 6 at the discharge end of the feeding assembly 5. A clamping assembly 8 is provided at the discharge end of the material separating component 7. The processing table 6 is equipped with... The hopper consists of a marking assembly 9, a material support base plate 2, a side plate 3, and a moving plate 4. It is used to store metal pipes that need to be processed. When the feeding assembly 5 is activated, the stacked metal pipes can be transported one by one to the material distribution assembly 7. Then, the material distribution assembly 7 guides the metal pipes to the L-shaped support plate 15 on the processing table 6. The L-shaped support plate 15 then lifts them upward. Then, the clamping assembly 8 is activated, and the top blocks at both ends converge inward, thereby clamping and fixing the metal pipes. Under the drive of the synchronous motor 86, the metal pipes can also rotate. Finally, the marking pen 95 of the marking assembly 9 marks the cutting auxiliary lines on the surface of the metal pipes.

[0024] Reference Figure 1-5The system includes an adjustment assembly 10 for driving the movable plate 4. The adjustment assembly 10 includes a locking flange 101 fixedly installed on the frame 1. An optical shaft 102 is slidably connected inside the locking flange 101. One end of the optical shaft 102 is fixedly connected to the movable plate 4, and the other end is provided with a control handle 103. A connecting shaft 104 is fixedly installed between one side surface of the control handle 103 and the movable plate 4, and the connecting shaft 104 is slidably connected to the frame 1 through a linear bearing 105.

[0025] With the above structural setup, the locking flange 101 is fixedly installed on the frame 1, providing sliding support for the optical axis 102. When it is necessary to adjust the position of the moving plate 4, the operator can push the control handle 103 to drive the optical axis 102 to slide within the locking flange 101. The sliding of the optical axis 102 then drives the moving plate 4 to move, thereby adjusting the position of the moving plate 4. The design of the connecting shaft 104 and the linear bearing 105 ensures the stability and straightness of the moving plate 4 during movement. Therefore, the moving plate 4 can be adjusted according to the model and length of the metal pipe, making it more flexible.

[0026] Reference Figure 1-5 The feeding assembly 5 includes a drive motor 51 fixedly mounted on the frame 1. The output end of the drive motor 51 is chain-driven to a drive shaft 52 rotatably connected to the frame 1. A driven shaft 53 is rotatably connected to the frame 1 via a bearing seat. The drive shaft 52 and the driven shaft 53 are connected by a chain drive mechanism 54. There are two chain drive mechanisms 54. Multiple feeding blocks 55 are arranged equidistantly on the chain of the chain drive mechanism 54.

[0027] With the above structural configuration, the drive motor 51 serves as the power source. The output end of the drive motor 51 is connected to the drive shaft 52, which is rotatably connected to the frame 1, via a chain drive. The rotational motion of the motor is transmitted to the drive shaft 52. The drive shaft 52 and the driven shaft 53 are connected by two chain drive mechanisms 54 to achieve power transmission and motion synchronization. Multiple feeding blocks 55 are arranged equidistantly on the chain of the chain drive mechanism 54. The feeding blocks 55 move with the rotation of the chain to form a continuous feeding conveyor line.

[0028] Reference Figure 1-5 The frame 1 is fixedly mounted with a fixed shaft 11 located between the drive shaft 52 and the driven shaft 53, and the fixed shaft 11 is provided with a platform-shaped support block 12 located in the chain drive mechanism 54.

[0029] With the above structural arrangement, the platform-shaped support block 12 is set on the fixed shaft 11 and located inside the chain drive mechanism 54, close to the chain, to support the middle area of ​​the chain during operation. When the chain drive mechanism 54 is running, the chain needs to bear the weight of the loading block 55 and the metal pipe, and the middle area may sag or shake. The platform-shaped support block 12 effectively supports the chain through its platform design, preventing the middle part from sag or shake, thereby ensuring the smooth operation of the chain.

[0030] Reference Figure 1-5 The material distribution component 7 includes a first connecting seat 71 fixedly installed on the processing table 6. A second connecting seat 72 slidably connected to the processing table 6 is symmetrically arranged with the first connecting seat 71. Both the first connecting seat 71 and the second connecting seat 72 are provided with inclined material conveying channels 73. A blocking block 74 is provided in the material conveying channel 73. A one-way cylinder 75 is provided on the first connecting seat 71, and a top material block 76 slidably connected to the material conveying channel 73 is fixedly installed at the telescopic end of the one-way cylinder 75.

[0031] With the above structural setup, the inlet end of the conveying channel 73 is connected to the outlet end of the feeding assembly 5. When metal pipes enter the conveying channel 73, they are temporarily blocked by the blocking block 74, which serves as a positioning function. When material separation is required, the one-way cylinder 75 is activated, and its telescopic end pushes the top material block 76 to slide on the conveying channel 73. The metal pipes blocked by the blocking block 74 pass over the blocking block 74 and fall onto the L-shaped support plate 15 below under the action of gravity. After the material separation is completed, the telescopic end of the one-way cylinder 75 retracts, driving the top material block 76 to reset, preparing for the next material separation. At the same time, the new metal pipes continue to advance forward in the conveying channel 73, are blocked by the blocking block 74, and wait for the next material separation action.

[0032] Reference Figure 1-5 The processing table 6 is equipped with a lead screw slide 13, and the second connecting seat 72 is located at the movable end of the lead screw slide 13.

[0033] Reference Figure 1-5 The clamping assembly 8 includes a fixed base 81. The first connecting base 71 and the second connecting base 72 are both provided with fixed bases 81. A first electric push rod 82 is fixedly installed on one of the fixed bases 81, and a first top block 83 is provided at the telescopic end of the first electric push rod 82. A second electric push rod 84 is fixedly installed on the other fixed base 81. A mounting base 85 is provided at the telescopic end of the second electric push rod 84, and a synchronous motor 86 is installed on the mounting base 85. A second top block 87 is provided at the output end of the synchronous motor 86. The opposite ends of the first top block 83 and the second top block 87 are both sharp.

[0034] With the above structural configuration, the metal pipe is lifted upward under the drive of the L-shaped support plate 15. Then, the first electric push rod 82 and the second electric push rod 84 are activated simultaneously. The telescopic end of the first electric push rod 82 pushes the first top block 83 to move towards the metal pipe until it is in close contact with one side of the metal pipe. The telescopic end of the second electric push rod 84 pushes the mounting base 85, the synchronous motor 86 and the second top block 87 to move towards the other side of the metal pipe until the second top block 87 is in close contact with the other side of the metal pipe. The opposite ends of the first top block 83 and the second top block 87 are both designed with a sharp shape, which helps to more accurately position the metal pipe and increase the contact pressure during clamping, thereby improving the stability and reliability of clamping.

[0035] Reference Figure 1-5 The marking assembly 9 includes a bracket 91 fixedly installed on the first connecting seat 71. The bracket 91 has a stroke hole 92, and a threaded rod 93 is provided in the stroke hole 92. A locking nut 94 is threaded to the outside of the threaded rod 93. A collar 97 is welded to one end of the threaded rod 93. A marking pen 95 is provided in the collar 97. A hand-tightening screw 96 with one end penetrating and extending to the inside is threaded to the collar 97, and one end of the hand-tightening screw 96 abuts against the marking pen 95.

[0036] With the above-described structure, the bracket 91 is fixedly installed on the first connecting seat 71, providing stable support for the marking operation. The bracket 91 has a stroke hole 92, through which the threaded rod 93 passes and can be adjusted in position to adapt to marking requirements of different sizes or positions. The threaded rod 93 is threadedly connected to a locking nut 94 on the outside. When the threaded rod 93 is adjusted to a suitable position, the locking nut 94 can be tightened to fix the threaded rod 93 on the bracket 91 to prevent it from moving. By tightening the hand screw 96, the marking pen 95 can be fixed in the collar 97 to ensure stability during marking.
