Description

Technical Field

[0001] This utility model relates to the field of springs, and in particular to a device for processing the end face of traction machine springs. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. Parts made of elastic materials deform under external force and return to their original shape after the force is removed. To ensure uniform force distribution, spring end faces often need to be treated. Existing traction machine spring end face treatment equipment only treats the end faces of springs of specific sizes. If a spring of a different diameter needs to be replaced, the clamping position often needs to be adjusted in real time, resulting in low efficiency and wasted time. Furthermore, it cannot treat the end faces of springs of multiple diameters simultaneously, leading to low processing efficiency and limited applicability.

[0003] Therefore, in order to solve the above problems, how to design a traction machine spring end face treatment device is a technical problem that the industry urgently needs to solve. Utility Model Content

[0004] The purpose of this invention is to provide a traction machine spring end face processing device to solve the problem mentioned in the background art of not being able to process spring end faces of multiple diameters at the same time.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A traction machine spring end face processing device includes a mounting plate with a mounting cavity inside. A docking frame is provided inside the mounting cavity. A set of symmetrical grinding devices is provided on the side of the docking frame. The grinding devices are not on the same side as the mounting plate. Several sets of clamping cavities are provided on the docking frame. Several sets of pushing devices are provided on the side of the mounting plate away from the docking frame. A clamping plate is provided on the side of the pushing device close to the docking frame. The clamping plate is located inside the mounting cavity and corresponds one-to-one with the clamping cavity.

[0007] Preferably, the end face of the clamping plate facing the clamping cavity is arc-shaped, and the clamping cavity is arc-shaped.

[0008] Preferably, the pushing device includes a limiting frame connected to a mounting plate. A threaded motor is installed inside the limiting frame, and a threaded screw is provided at the drive end of the threaded motor. A threaded slider is provided on the outer surface of the threaded screw, and the threaded slider is threadedly engaged with the threaded screw. The threaded slider abuts against the limiting frame, and a pushing plate is provided on the threaded slider. The pushing plate cooperates with the limiting frame to cover the threaded screw, and the end of the pushing plate near the docking frame is connected to a clamping plate.

[0009] Preferably, the grinding device includes a positioning frame connected to a docking frame. The positioning frame has several sets of moving components that correspond one-to-one with the clamping cavities at one end near the docking frame. The moving components have grinding components at one end near the docking frame, and the grinding components have powder recovery components.

[0010] Preferably, the moving component includes an electric telescopic rod, one end of which is connected to the positioning frame, and a pressure sensor is provided at the extended end of the electric telescopic rod.

[0011] Preferably, the grinding assembly includes a storage rack, the end of which is away from the docking rack is connected to a pressure sensor, a power motor is provided inside the storage rack, a power shaft is provided at the drive end of the power motor, and a grinding plate is provided at the end of the power shaft near the docking rack.

[0012] Preferably, the powder recovery assembly includes a recovery frame connected to the side of a storage frame. The recovery frame has an exhaust chamber with a bent shape. The inlet of the exhaust chamber is located in front of the grinding plate. The exhaust chamber has a filter plate and an exhaust fan. The exhaust fan inlet is connected to the filter plate.

[0013] Preferably, a protective assembly is provided below the mounting plate, the protective assembly including a protective housing, and a set of symmetrical sealing covers are rotatably provided inside the protective housing.

[0014] Preferably, the protective housing is equipped with a controller.

[0015] The beneficial effects of this utility model are:

[0016] 1. By activating the push device, the clamping plate moves towards the clamping cavity, simultaneously clamping and positioning springs of various diameters. This ensures that springs of different diameters can be clamped at the same time. Furthermore, the arc-shaped end faces of the clamping plate and the clamping cavity significantly increase the contact force and clamping force on the springs, thus ensuring the stability of subsequent grinding of the spring end faces.

[0017] 2. By sequentially placing springs of various diameters into the clamping cavity, the pushing device is activated, causing the clamping plate to move towards the clamping cavity. At this time, springs of various diameters are clamped and positioned simultaneously. Then, in conjunction with the grinding device, the end faces of springs of various different diameters can be ground simultaneously. This ensures that the factory can transform a single model grinding mode into multiple modes, thereby ensuring both production efficiency and the factory's applicability.

[0018] 3. During the grinding process, the exhaust fan in the powder recovery component is activated, generating suction. This suction enters the exhaust chamber through the inlet on the front side of the grinding plate. The powder is then separated by the filter plate, causing the ground iron powder to accumulate in the exhaust chamber. Because the exhaust chamber is designed in a bent shape, it ensures that the iron powder is stored without spilling out. Attached Figure Description

[0029] 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.

[0030] See Figures 1-6 This utility model provides a traction machine spring end face processing device, including a mounting plate 1, a mounting cavity 14 inside the mounting plate 14, a docking frame 2 inside the mounting cavity 14, a symmetrical set of grinding devices 3 on the side of the docking frame 2, the grinding devices 3 not on the same side as the mounting plate 1, a plurality of clamping cavities 13 on the docking frame 2, a plurality of pushing devices 11 on the side of the mounting plate 1 away from the docking frame 2, and a clamping plate 12 on the side of the pushing device 11 closer to the docking frame 2, the clamping plate 12 being located in the mounting cavity 14 and corresponding one-to-one with the clamping cavity 13. By sequentially placing springs of various diameters into the clamping cavities 13, the pushing devices 11 are activated, thereby driving the clamping plates 12 to move towards the clamping cavities 13, thus simultaneously clamping and positioning springs of various diameters, and then cooperating with the grinding devices 3, thereby simultaneously processing the end faces of springs of various diameters.

[0031] See Figure 4 Specifically, the end face of the clamping plate 12 facing the clamping cavity 13 is arc-shaped, and the clamping cavity 13 is also arc-shaped. The arc-shaped end faces of the clamping plate 12 and the clamping cavity 13 significantly increase the contact force and clamping force on the spring.

[0032] See Figures 4-7 Specifically, the pushing device 11 includes a limiting frame 111, which is connected to the mounting plate 1. A threaded motor 112 is provided inside the limiting frame 111. A threaded screw 113 is provided at the driving end of the threaded motor 112. A threaded slider 114 is provided on the outer surface of the threaded screw 113. The threaded slider 114 is threadedly engaged with the threaded screw 113. The threaded slider 114 abuts against the limiting frame 111. A pushing plate 115 is provided on the threaded slider 114. The pushing plate 115 cooperates with the limiting frame 111 to cover the threaded screw 113. The end of the pushing plate 115 near the docking frame 2 is connected to the clamping plate 12. When the threaded motor 112 in the pushing device 11 is started, it drives the threaded screw 113 to start rotating, thereby pushing the threaded slider 114 and the clamping plate 12 to move towards the clamping cavity 13. The pushing plate 115 and the limiting frame 111 cooperate to cover the threaded screw 113, ensuring that no iron filings will enter during use.

[0033] See Figures 4-7 Specifically, the grinding device 3 includes a positioning frame 31 connected to the docking frame 2. At one end of the positioning frame 31 near the docking frame 2, several sets of moving components 32 are provided, each corresponding to a clamping cavity 13. At the other end of each moving component 32 near the docking frame 2, a grinding component 33 is provided, and a powder recovery component 34 is provided on the grinding component 33. The moving components 32 in the grinding device 3 push the grinding component 33 and the powder recovery component 34 towards the clamping spring end face, thereby performing subsequent grinding and powder recovery.

[0034] See Figures 4-7 Specifically, the moving component 32 includes an electrically operated telescopic rod 321, one end of which is connected to the positioning frame 31, and a pressure sensor 322 is provided at the extended end of the electrically operated telescopic rod 321. When the electrically operated telescopic rod 321 of the moving component 32 begins to extend, it drives the pressure sensor 322 to move.

[0035] More preferably, the pressure sensor 322 is a strain gauge sensor with a range of 100N and an accuracy of ±0.5%FS, thereby ensuring positioning when the grinding component 33 contacts the spring.

[0036] See Figures 4-7 Specifically, the grinding assembly 33 includes a storage rack 331. The end of the storage rack 331 furthest from the docking rack 2 is connected to a pressure sensor 322. A power motor 332 is housed within the storage rack 331. A power shaft 333 is located at the drive end of the power motor 332. A grinding plate 334 is located at the end of the power shaft 333 closest to the docking rack 2. When the grinding assembly 33 is positioned according to the pressure sensor 322, the grinding plate 334 contacts the spring. At this time, the power motor 332 starts, causing the power shaft 333 to rotate, which in turn causes the grinding plate 334 to start rotating, thereby grinding the end face of the spring.

[0037] See Figures 4-7Specifically, the powder recovery assembly 34 includes a recovery frame 341, which is connected to the side of a storage frame 331. The recovery frame 341 has an exhaust chamber 342, which is bent in shape. The inlet of the exhaust chamber 342 is located in front of the grinding plate 334. A filter plate 343 and an exhaust fan 344 are both located within the exhaust chamber 342, with the air inlet of the exhaust fan 344 connected to the filter plate 343. When the exhaust fan 344 is activated in the powder recovery assembly 34, it generates suction. This suction enters the exhaust chamber 342 through the inlet in front of the grinding plate 334. The powder is then separated by the filter plate 343, causing the iron powder from the grinding process to accumulate in the exhaust chamber 342.

[0038] More preferably, the exhaust fan 344 is a dry industrial vacuum cleaner model: Nilfisk ATTIX 970-21, which is used to remove iron filings.

[0039] See Figure 5 Specifically, a protective component 4 is provided below the mounting plate 1. The protective component 4 includes a protective shell 41, and a set of symmetrical sealing covers 43 are rotatably provided inside the protective shell 41.

[0040] See Figure 5 Specifically, the protective housing 41 is equipped with a controller 42.

[0041] More preferably, the controller 42 adopts a Siemens PLC controller to meet the control requirements of the motor and the electric telescopic rod.

[0042] Working principle of this utility model:

[0043] In use, springs of various diameters are sequentially placed into the clamping cavity 13. At this time, the threaded motor 112 in the pushing device 11 starts, thereby driving the threaded screw 113 to rotate, which in turn pushes the threaded slider 114 and the clamping plate 12 to move towards the clamping cavity 13. At this time, springs of various diameters are clamped and positioned simultaneously. Then, the electric telescopic rod 321 of the moving component 32 in the grinding device 3 begins to extend, thereby driving the pressure sensor 322 to move and pushing the grinding plate 334 in the grinding component 33 to contact the spring. At this time, the power motor 332 starts, thereby driving the power shaft 333 to rotate, which in turn drives the grinding plate 334 to start, thereby grinding the end face of the spring. This achieves simultaneous grinding of the end face of springs of various diameters.

[0044] During the grinding process, the exhaust fan 344 in the powder recovery component 34 is activated, generating suction. The suction enters the exhaust chamber 342 through the inlet on the front side of the grinding plate 334. The powder is then separated by the filter plate 343, causing the iron powder from the grinding process to accumulate in the exhaust chamber 342.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
