Description

Technical Field

[0001] This application relates to the field of spring manufacturing equipment, and more particularly to a spring grinding equipment. Background Technology

[0002] Springs are widely used components. After the spring is manufactured, the ends of the spring need to be ground to ensure that the length of the spring meets the standard and that the ends of the spring are flat.

[0003] The existing spring grinding operation is completed by a grinding machine, which includes a frame, a grinding wheel and a motor. The motor is mounted on the frame, and the grinding wheel is rotatably connected to the frame. The motor drives the grinding wheel to rotate. The user holds the spring and puts the end of the spring against the grinding wheel, which allows the grinding wheel to grind the end of the spring to achieve the processing purpose.

[0004] The aforementioned technical solutions have the following drawbacks: users need to hold the spring by hand to perform grinding operations at both ends of the spring, resulting in low production efficiency. Utility Model Content

[0005] In order to improve the production efficiency of spring grinding operations, this application provides a spring grinding equipment.

[0006] The spring grinding equipment provided in this application adopts the following technical solution:

[0007] A spring grinding device includes a machine body, a clamping table, and a grinding mechanism. The clamping table is disposed in the machine body and includes an upper mounting table, a lower mounting table, multiple elastic cylinders, a rotating shaft, and a driving mechanism. The rotating shaft is vertically arranged and rotatably connected to the machine body. The driving mechanism is installed in the machine body and drives the rotating shaft to rotate. The upper and lower mounting tables are disc structures and are coaxially connected to the rotating shaft. The upper mounting table is used to slide vertically on the rotating shaft. A pressing mechanism is provided in the machine body to control the vertical sliding of the upper mounting table. Multiple through holes are opened on the upper and lower mounting tables, and the elastic cylinders are disposed between the upper and lower mounting tables.

[0008] By adopting the above technical solution, a clamping platform is set on the machine body, allowing the upper and lower mounting platforms to rotate via a rotating shaft. The user can vertically insert the spring into the through holes of the upper and lower mounting platforms. By controlling the pressing mechanism, the user can make the upper mounting platform slide down and, together with the lower mounting platform, squeeze the elastic cylinder, causing the elastic cylinder to deform and clamp the spring, thus achieving the effect of vertically fixing the spring in the clamping platform. During the rotation of the spring driven by the upper and lower mounting platforms, the spring moves and comes into contact with the grinding mechanism, thereby enabling the grinding mechanism to automatically grind the end of the spring, improving production efficiency.

[0009] Optionally, the rotating shaft is provided with several guide keys, which are engaged with the upper mounting platform.

[0010] By adopting the above technical solution, a guide key is set on the rotating shaft, which protrudes and is locked on the upper mounting platform, thereby reducing the probability of the upper mounting platform rotating relative to the rotating shaft. This ensures that the spring installed in the clamping table can always remain in a vertical state, resulting in higher machining accuracy.

[0011] Optionally, the pressing mechanism includes a telescopic component and a cylinder. The telescopic component is vertically arranged above the rotating shaft, and the cylinder is connected to the lower end of the telescopic component. The cylinder is used to cover the end of the rotating shaft and abut against the upper mounting platform.

[0012] By adopting the above technical solution, by setting a telescopic component above the upper mounting platform, the telescopic component can drive the cylinder to move vertically back and forth. When the cylinder falls vertically, the cylinder cover is placed on the end of the rotating shaft, and the end face of the bottom of the cylinder presses on the upper mounting platform, so that the upper mounting platform and the lower mounting platform can jointly clamp the elastic cylinder, causing the elastic cylinder to deform and clamp the spring.

[0013] Optionally, a plurality of balls are provided on the lower end face of the cylinder. The balls are embedded in the cylinder and rotatably connected to the cylinder. The balls are used to abut against the end face of the upper mounting platform.

[0014] By adopting the above technical solution, ball bearings are installed on the lower end face of the cylinder, so that the cylinder abuts against the upper mounting platform through the ball bearings. When the upper and lower mounting platforms rotate, the ball bearings rotate on the cylinder, thereby reducing the wear on the cylinder and the upper mounting platform.

[0015] Optionally, the grinding mechanism includes a grinding wheel, a power mechanism, and a lifting platform. The lifting platform is slidably connected to the machine body, the power mechanism is mounted on the lifting platform, the grinding wheel is rotatably connected to the lifting platform, the power mechanism drives the grinding wheel to rotate, the axis of the grinding wheel is parallel to the length direction of the rotating shaft, and the lifting platform is used to drive the grinding wheel to move in the vertical direction.

[0016] By adopting the above technical solution, by setting a grinding wheel and a power mechanism on the lifting platform, the lifting platform can drive the grinding wheel to move vertically. When the user places springs of different lengths in the clamping table, the end positions of the springs are different. The user can adjust the position of the lifting platform so that the grinding wheel can grind the ends of the springs.

[0017] Optionally, the lifting platform is provided with a screw and a guide rod, which are vertically arranged. The lower end of the screw is rotatably connected to the machine body and passes through the lifting platform and is threadedly connected to the lifting platform. The lower end of the guide rod is fixed to the machine body and passes through the lifting platform and is slidably connected to the lifting platform.

[0018] By adopting the above technical solution, a screw and a guide rod are installed on the lifting platform, allowing the lifting platform to slide along the direction of the guide rod. When the user rotates the screw, the screw rotates relative to the lifting platform, and at this time, relative movement occurs between the screw and the lifting platform, thereby achieving the effect of controlling the vertical lifting of the lifting platform.

[0019] Optionally, the grinding mechanism is configured as two, with the grinding wheels of the two grinding mechanisms respectively positioned above the upper mounting platform and below the lower mounting platform.

[0020] By adopting the above technical solution, two grinding mechanisms are set on the machine body, which can grind the upper and lower ends of the spring respectively. The user can control the position of the two grinding wheels respectively, so that the ends of springs of different lengths can abut on the grinding wheels and be ground.

[0021] Optionally, a rotating platform is rotatably connected to the body, the rotating platform being used to rotate to a horizontal state and located below the lower mounting platform.

[0022] By adopting the above technical solution, a rotating platform is set on the machine body. When the rotating platform rotates to a horizontal state, it is located below the lower mounting platform. At this time, the upper mounting platform moves up, and the spring held in the clamping table can fall on the rotating platform. When the user inserts the spring into the clamping table, the lower end of the spring abuts against the rotating platform, which achieves the effect of positioning the spring and improving processing efficiency.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By setting a clamping platform on the machine body, the upper and lower mounting platforms can rotate via a rotating shaft. The user can vertically insert the spring into the through holes of the upper and lower mounting platforms. By controlling the pressing mechanism, the user can make the upper mounting platform slide down and squeeze the elastic cylinder together with the lower mounting platform, causing the elastic cylinder to deform and clamp the spring, thus achieving the effect of vertically fixing the spring in the clamping platform. During the rotation of the spring driven by the upper and lower mounting platforms, the spring moves and comes into contact with the grinding mechanism, thereby enabling the grinding mechanism to automatically grind the end of the spring, improving production efficiency.

[0025] 2. By setting a telescopic component above the upper mounting platform, the telescopic component can drive the cylinder to move vertically back and forth. When the cylinder falls vertically, the cylinder covers the end of the rotating shaft, and the bottom end face of the cylinder presses on the upper mounting platform, so that the upper mounting platform and the lower mounting platform can jointly clamp the elastic cylinder, causing the elastic cylinder to deform and clamp the spring.

[0026] 3. By setting a grinding wheel and a power mechanism on the lifting platform, the lifting platform can drive the grinding wheel to move vertically. When the user places springs of different lengths in the clamping table, the ends of the springs will be in different positions. The user can adjust the position of the lifting platform so that the grinding wheel can grind the ends of the springs. Attached Figure Description

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a spring grinding device, referring to... Figure 1 , Figure 2 and Figure 3The system includes a body 1, a clamping table 2, and a grinding mechanism 3. The clamping table 2 and the grinding mechanism 3 are mounted on the body 1. The clamping table 2 includes an upper mounting platform 21, a lower mounting platform 22, multiple elastic cylinders 23, a rotating shaft 24, and a drive mechanism 25. The rotating shaft 24 is vertically arranged and rotatably connected to the body 1. The upper mounting platform 21 and the lower mounting platform 22 are disc structures and are coaxially connected to the rotating shaft 24. The lower mounting platform 22 is fixedly connected to the rotating shaft 24, and the upper mounting platform 21 is slidably connected to the rotating shaft 24. The drive mechanism 25 can be a motor, which drives the rotating shaft 24 to rotate, thereby causing the upper mounting platform 21 and the lower mounting platform 22 to rotate within the body 1. Multiple through holes are equidistantly spaced along the circumference of the upper mounting platform 21 and the lower mounting platform 22. The positions of these through holes correspond one-to-one, and they are used to insert springs. An elastic cylinder 23 is installed between the upper mounting platform 21 and the lower mounting platform 22, coaxially with the through holes. When the spring is inserted into the upper mounting platform 21 and the lower mounting platform 22, it is positioned within the elastic cylinder 23. The elastic cylinder 23 is made of rubber. After the spring is positioned on the clamping platform 2, the user controls the upper mounting platform 21 to fall, causing the upper mounting platform 21 and the lower mounting platform 22 to jointly compress the elastic cylinder 23, thereby compressing the spring and ensuring its stable installation on the upper mounting platform 21 and the lower mounting platform 22. The grinding mechanism 3 is located on one side of the machine body 1. The grinding mechanism 3 is used to process the end of the spring. When the spring is installed on the clamping table 2, the upper mounting table 21 and the lower mounting table 22 rotate through the rotating shaft 24, so that multiple springs on the upper mounting table 21 and the lower mounting table 22 can pass through the grinding mechanism 3 respectively, thereby improving the working efficiency of grinding the spring.

[0035] Reference Figure 2 The machine body 1 is equipped with a rotating platform 11, which is connected to the machine body 1. When the diameters of the upper mounting platform 21 and the lower mounting platform 22 are large, the edges of the upper mounting platform 21 and the lower mounting platform 22 extend outside the machine body 1. When the upper mounting platform 21 slides away from the lower mounting platform 22, the elastic cylinder 23 deforms, and the spring disengages from the elastic cylinder 23, causing the spring to fall to the ground. The user can rotate the rotating platform 11 to a horizontal state so that the rotating platform 11 can be located below the lower mounting platform 22 and support the spring, thus facilitating the user to collect the processed spring.

[0036] Reference Figure 4 The grinding mechanism 3 includes a grinding wheel 31, a power mechanism 32, and a lifting platform 33. The grinding wheel 31 is rotatably connected to the lifting platform 33, and the axis of the grinding wheel 31 is parallel to the rotating shaft 24. The power mechanism 32 can be a motor, which drives the grinding wheel 31 to rotate. The lifting platform 33 is slidably connected to the machine body 1 and is used to drive the grinding wheel 31 to move vertically. By vertically moving the lifting platform 33, the user can move the grinding wheel 31, thereby enabling the grinding wheel 31 to process springs of different lengths, which is convenient for use.

[0037] Reference Figure 4 The lifting platform 33 is equipped with a screw 331 and a guide rod 332, which are vertically arranged. One end of the guide rod 332 is fixed to the machine body 1, and the other end passes through the lifting platform 33 and is slidably connected to it. The lower end of the screw 331 is rotatably connected to the machine body 1, and the upper end passes through the lifting platform 33 and is threadedly connected to it. By rotating the screw 331, the user can make it slide relative to the lifting platform 33, thereby allowing the lifting platform 33 to move vertically. This facilitates the user in adjusting the position of the grinding wheel 31, enabling the grinding wheel 31 to grind the end of the spring.

[0038] Reference Figure 4 There are two grinding mechanisms 3, with the grinding wheels 31 of the two grinding mechanisms 3 respectively located on the upper side of the upper mounting platform 21 and the lower side of the lower mounting platform 22. By adjusting the positions of the two grinding wheels 31, the user can make the two grinding wheels 31 grind the upper end and the lower end of the spring respectively.

[0039] Reference Figure 5 The machine body 1 is equipped with a pressing mechanism 4, which controls the vertical sliding of the upper mounting platform 21 relative to the rotating shaft 24. The pressing mechanism 4 includes a telescopic component 41, a cylinder 42, and multiple balls 43. The telescopic component 41 can be an electric push rod. The telescopic component 41 is vertically positioned above the upper mounting platform 21. The upper end of the telescopic component 41 is fixed to the machine body 1, and the lower end is fixedly connected to the cylinder 42. The cylinder 42 is used to fall vertically and press against the center of the upper mounting platform 21, thereby allowing the upper mounting platform 21 to move up and down on the rotating shaft 24. Multiple balls 43 are engaged with the lower end face of the cylinder 42 along the circumference of the cylinder 42. The balls 43 can roll on the cylinder 42. When the cylinder 42 falls, the upper end of the rotating shaft 24 is inserted into the cylinder 42, and the balls 43 abut against the upper mounting platform 21, causing the upper mounting platform 21 to fall. This causes the upper mounting platform 21 and the lower mounting platform 22 to jointly compress the elastic cylinder 23. When the upper mounting platform 21 and the lower mounting platform 22 rotate, the ball bearing 43 can rotate with the upper mounting platform 21, thereby reducing wear on the surfaces of the upper mounting platform 21 and the cylinder 42. Multiple guide keys 241 are provided on the rotating shaft 24, with the length direction of the guide keys 241 parallel to the length direction of the rotating shaft 24. A through hole is opened in the middle of the upper mounting platform 21, and the guide keys 241 and the rotating shaft 24 are inserted into the through hole and engaged with the upper mounting platform 21, thereby reducing the probability of the upper mounting platform 21 rotating relative to the rotating shaft 24, and keeping the spring vertical on the upper mounting platform 21 and the lower mounting platform 22.

[0040] The implementation principle of this application embodiment is as follows: by setting a clamping table 2 in the machine body 1, the spring can be vertically inserted into the through holes on the upper mounting table 21 and the lower mounting table 22. The user controls the pressing mechanism 4 to operate, so that the upper mounting table 21 and the lower mounting table 22 jointly squeeze the elastic cylinder 23, thereby clamping the spring in the elastic cylinder 23 and improving the working efficiency of grinding the spring.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
