Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing, and in particular to a hammering device for mechanical parts processing. Background Technology

[0002] Hammering devices for machining mechanical parts are mainly used in forging, shaping, and straightening of metal parts. They are suitable for mass production in industries such as automotive parts and hardware products. By providing controllable impact force, the hammering device meets the core requirements of forming, straightening, surface treatment, and assembly in mechanical parts machining. It is particularly irreplaceable in terms of flexibility, cost control, and processing of special materials. Existing hammering devices for machining mechanical parts typically employ cam drives, where the cam compresses the hammer rod to move up and down, achieving the hammering effect.

[0003] However, existing semi-automatic devices use cam drives, and the hammering frequency is easily affected by the load. They cannot automatically hammer and hammer parts by free fall. When processing large parts, cam wear causes frequency fluctuations and disordered hammering rhythm, which affects the surface flatness of the parts. Therefore, a hammering device for machining mechanical parts is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a hammering device for machining mechanical parts, which aims to improve the problem that the existing technology cannot automatically hammer and relies on free fall to hammer the parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hammering device for machining mechanical parts, comprising a machining table, a top frame fixedly connected to the top of the machining table, an auxiliary block fixedly connected to the left side of the inner wall of the top frame, a threaded rod rotatably connected through the inner wall of the auxiliary block, a threaded sleeve threadedly connected to the threaded surface of the threaded rod, an inner box fixedly connected to the right side of the outer wall of the threaded sleeve, a sliding sleeve fixedly connected to the right side of the outer wall of the inner box, a sliding rod slidably connected through the inner wall of the sliding sleeve, a motor fixedly connected to the inner wall of the back of the inner box, a turntable fixedly connected to the output end of the motor, a pressing rod fixedly connected to the front of the turntable, a hammer rod contacting a hammer, and a hammering block fixedly connected to the bottom of the hammer rod.

[0006] As a further description of the above technical solution: A counterweight platform is fixedly connected to the back of the hammer, and a bolt is fixedly connected to the top of the counterweight platform. A counterweight block is inserted into the outer arc surface of the bolt, and a nut is threadedly connected to the top of the bolt.

[0007] As a further description of the above technical solution: The end of the threaded rod is rotatably connected to the inner left wall of the top frame, and the slide rod is fixedly connected to the inner right wall of the top frame.

[0008] As a further description of the above technical solution: The outer side of the threaded sleeve is slidably connected to the inner wall of the top frame, and the outer side of the sliding sleeve is slidably connected to the inner wall of the top frame.

[0009] As a further description of the above technical solution: The turntable is rotatably connected to the inner wall of the inner box, the hammer rod is slidably connected to the inner wall of the inner box, and the hammer rod is slidably connected to the inner wall of the top frame.

[0010] As a further description of the above technical solution: The outer end of the extrusion rod is slidably connected to the inner wall of the inner box.

[0011] As a further description of the above technical solution: The counterweight platform is slidably connected to the inner wall of the back of the inner box.

[0012] As a further description of the above technical solution: The bottom of the nut is in contact with the top of the counterweight.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the height of the inner box can be flexibly adjusted by the cooperation of the threaded rod and the threaded sleeve, which can accurately adapt to the processing needs of mechanical parts of different sizes, avoid damage to parts due to improper hammering height, and improve the adaptation efficiency.

Whether it is fine shaping or strong forging, it can be adjusted as needed. Compared with the traditional fixed force hammering device, the applicable scenarios are expanded.

[0014] 2. In this utility model, the turntable driven by the motor drives the extrusion rod to achieve stable and automated hammering, which improves efficiency compared to manual hammering. The inner box and sliding sleeve, together with the guide structure of the sliding rod, ensure that the hammer moves vertically, avoiding uneven deformation of parts due to hammering deviation, and improving the part processing qualification rate.

[0017] 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 protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a hammering device for machining mechanical parts, including a machining table 1, which is a placement platform for hammering mechanical parts. A top frame 2 is fixedly connected to the top of the machining table 1. The top frame 2 provides movable space for the inner box 6 and provides it with support. An auxiliary block 3 is fixedly connected to the left side of the inner wall of the top frame 2. The auxiliary block 3 is used to keep the threaded rod 4 rotating in the center and provides it with the origin of rotation. The threaded rod 4 is rotatably connected through the inner wall of the auxiliary block 3. The threaded rod 4 is used to drive the threaded sleeve 5 to move up and down by threaded rotation. The threaded surface of the threaded rod 4 is threadedly connected to the threaded sleeve 5. The threaded sleeve 5 is provided in two sets, upper and lower. The two sets of threaded sleeves 5 are connected by the threaded rod 4, so that the inner box 6 can be stably raised, thereby... Adjust the height of the inner box 6 to change the initial height of the hammer rod 12 and the hammer block 13. The inner box 6 is fixedly connected to the right side of the outer wall of the threaded sleeve 5. The inner box 6 is used to keep the hammer rod 12 vertically and stably moving up and down, and to provide guidance for it. The sliding sleeve 7 is fixedly connected to the right side of the outer wall of the inner box 6. The sliding sleeve 7 is used to engage the sliding rod 8 to keep the inner box 6 moving up and down stably. The inner wall of the sliding sleeve 7 is slidably connected to the sliding rod 8. The sliding rod 8 is used to provide support for the right side of the inner box 6 and keep it moving up and down stably. The end of the threaded rod 4 is rotatably connected to the left inner wall of the top frame 2. The sliding rod 8 is fixedly connected to the right inner wall of the top frame 2. The outer side of the threaded sleeve 5 is slidably connected to the inner wall of the top frame 2. The outer side of the sliding sleeve 7 is slidably connected to the inner wall of the top frame 2.

[0019] Reference Figures 2-4A motor 9 is fixedly connected to the inner wall of the back of the inner box 6. Motor 9 is existing technology and will not be described in detail. It drives the turntable 10 to rotate. The output end of motor 9 is fixedly connected to the turntable 10. The turntable 10 drives the extrusion rod 11 to move in a circular motion around its center point. The extrusion rod 11 is fixedly connected to the front of the turntable 10. The extrusion rod 11, driven by the turntable 10, extrudes the hammer rod 12 upwards. The extrusion rod 11 contacts the hammer rod 12. The hammer rod 12 has a quarter-circle arc in its middle, and an extended plane on the top surface of the arc. The extrusion rod 11 contacts the bottom surface of the arc of the hammer rod 12. Sliding upwards, the pressure on the top plane of the arc surface causes the hammer rod 12 to move upwards. When the pressure rod 11 is separated from the top plane, the hammer rod 12 is in a non-contact state, causing the hammer rod 12 to fall due to its own weight, achieving a hammering effect. A hammering block 13 is fixedly connected to the bottom of the hammer rod 12. The hammering block 13 is used to contact the mechanical parts, thereby striking them and changing their shape. The turntable 10 is rotatably connected to the inner wall of the inner box 6. The hammer rod 12 passes through and is slidably connected to the inner wall of the inner box 6. The hammer rod 12 passes through and is slidably connected to the inner wall of the top frame 2. The outer end of the pressure rod 11 is slidably connected to the inner wall of the inner box 6.

[0020] Reference Figures 3-4 A counterweight platform 14 is fixedly connected to the back of the hammer 12. The counterweight platform 14 is used to place the counterweight 16. By placing counterweights 16 of different weights, the weight of the hammer 12 and the hammering block 13 is changed. A bolt 15 is fixedly connected to the top of the counterweight platform 14. The top of the bolt 15 has a threaded surface for threaded connection of the nut 17 to restrict the movement of the counterweight 16. The outer arc surface of the bolt 15 is inserted into the counterweight 16. The counterweight 16 is existing technology and will not be described in detail. The top of the bolt 15 is threadedly connected to the nut 17. The nut 17 is used to fix the counterweight 16 on the counterweight platform 14 so that its weight is integrated with the hammer 12. The counterweight platform 14 is slidably connected to the inner wall of the back of the inner box 6. The bottom of the nut 17 is in contact with the top of the counterweight 16.

[0021] Working principle: During the machining of mechanical parts, the motor 9 is turned on, driving the turntable 10 to rotate. This causes the pressing rod 11, fixed at the front of the turntable 10, to move in a circular motion. When the pressing rod 11 contacts the bottom surface of the quarter-circle arc in the middle of the hammer rod 12, as the turntable 10 rotates, the pressing rod 11 slides upward along the arc surface, pushing the hammer rod 12 upward against gravity. When the pressing rod 11 slides to the extended plane at the top of the arc, it continues to press the hammer rod 12 to its highest position. Subsequently, the pressing rod 11 leaves the plane, and the hammer rod 12 falls due to its own gravity, causing the hammering block 13 at the bottom to strike the machine on the machining table 1. The mechanical parts are hammered, and the turntable 10 rotates continuously, causing the hammer rod 12 to cycle through the rising and falling hammering motion. When the hammering height is different, the threaded rod 4 is rotated, and its threaded connection with the threaded sleeve 5 drives the upper and lower sets of threaded sleeves 5 to move up and down synchronously. The outer side of the threaded sleeve 5 is slidably connected to the inner wall of the top frame 2 to ensure the stability of the movement. At the same time, the sliding sleeve 7 on the right side slides up and down along the sliding rod 8, changing the overall height of the inner box 6. After adjusting to the target height, the threaded rod 4 is supported and fixed by the auxiliary block 3, thereby adjusting the initial height of the hammer rod 12 and the hammering block 13 to adapt to different processing requirements.

[0022] When the hammering force during processing is different, counterweights 16 of different weights are placed on the counterweight platform 14. The counterweights 16 are passed through by bolts 15 and then tightened with nuts 17, so that the weight of the counterweights 16 is integrated with the hammer rod 12 and the hammering block 13. The weight of the counterweights 16 changes the falling inertia of the hammer rod 12, thereby adjusting the hammering force. The heavier the counterweights 16, the greater the impact force when the hammering block 13 falls, which is suitable for processing scenarios that require large deformation. Conversely, it is suitable for fine hammering.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
