Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, and in particular to a spring end face chamfering device. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. A part made of elastic material deforms under external force and returns to its original shape after the force is removed. Springs are generally made of spring steel. There are many types of springs; according to shape, they mainly include helical springs, spiral springs, leaf springs, and irregularly shaped springs.

[0003] After the spring is manufactured, the two ends of the spring are processed to meet the installation requirements. The two ends of the spring are ground to make the spring easier to install. Currently, due to the shape of the spring, the two ends are directly cut to make the two ends parallel and equal. This processing method is costly and the ends of the spring are too sharp, which can easily cause danger. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems and shortcomings by proposing a chamfering device for the end face of a spring: a grinding motor and an adjusting motor respectively drive the adjusting screw to rotate and the grinding cylinder to rotate. The rotation of the adjusting screw drives the grinding cylinder to approach one end of the spring via a support rod. After the grinding cylinder fits one end of the spring, it rotates to grind that end of the spring. This facilitates the processing of both ends of the spring, makes it easy to use, reduces the cost of use, and solves the problem of sharp ends caused by direct cutting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spring end face chamfering device includes a base, an extension rod welded to one outer wall of the base, and a grinding structure rotatably connected to the top of one end of the extension rod. A fixing rod is installed at the center of the top outer wall of the base, and a fixing groove is formed on one outer wall of the fixing rod.

The grinding structure includes a rotating rod, an adjustment groove formed at the center of the top outer wall of the rotating rod, an adjustment screw rotatably connected to the rotating rod at the center of the adjustment groove, and a support rod threaded to the outer wall of the adjustment screw.

[0007] According to the above scheme: the grinding motor and the adjusting motor drive the adjusting screw to rotate and the grinding cylinder to rotate, respectively. The rotation of the adjusting screw drives the grinding cylinder to move closer to one end of the spring through the support rod. After the grinding cylinder fits one end of the spring, it rotates to grind one end of the spring. This makes it easier to process both ends of the spring, making it easier to use and reducing the cost of use.

[0008] Preferably, the bottom outer wall of the support rod is slidably connected to the inner wall of the adjustment groove, and one end of the rotating rod is provided with a connection hole at the extension rod.

[0009] Preferably, a grinding motor is installed on the top outer wall of the support rod at the center of the fixed rod, and the output shaft of the grinding motor is connected to a grinding cylinder.

[0010] Preferably, a fixed motor is installed on the outer wall of the top end of the fixed rod, and the output shaft of the fixed motor is connected to one end of the bidirectional screw. An adjusting motor is installed on the outer wall of one end of the rotating rod, and the output shaft of the adjusting motor is connected to one end of the adjusting screw.

[0011] Preferably, both ends of the bidirectional screw are threaded to the outer walls of the screw, and the other end of the threaded screw is symmetrically welded with an arc-shaped plate. The inner outer wall of the arc-shaped plate is provided with anti-slip strips distributed at equal intervals, and one end of the threaded screw is slidably connected to the inner wall of the fixed groove.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0020] Reference Figure 1-3 A spring end face chamfering device includes a base 1, an extension rod 2 welded to one side outer wall of the base 1, and a grinding structure 3 rotatably connected to the top of one end of the extension rod 2. A fixing rod 4 is installed at the center of the top outer wall of the base 1, and a fixing groove 5 is opened on one side outer wall of the fixing rod 4. A bidirectional screw 6 is rotatably connected to the fixing rod 4 at the center of the fixing groove 5.

[0021] The grinding structure 3 includes a rotating rod 13, an adjustment groove 15 located at the center of the outer wall of the top of the rotating rod 13, an adjustment screw 16 rotatably connected to the rotating rod 13 at the center of the adjustment groove 15, and a support rod 18 threadedly connected to the outer wall of the adjustment screw 16. The rotation of the adjustment screw 16 drives the grinding cylinder 20 to approach one end of the spring through the support rod 18. After the grinding cylinder 20 fits one end of the spring, it rotates to grind one end of the spring. Different grinding heads can be used to achieve different effects on one end of the spring, making it easy to process both ends of the spring, convenient to use, and reducing the cost of use.

[0022] The bottom outer wall of the support rod 18 is slidably connected to the inner wall of the adjustment groove 15, and one end of the rotating rod 13 is provided with a connecting hole 14 at the extension rod 2. The rotating rod 13 is connected to one end of the extension rod 2 through the connecting hole 14, which facilitates the adjustment of the orientation of the grinding cylinder 20, facilitates contact with one end of the spring, and facilitates the processing of one end of the spring.

[0023] A grinding motor 19 is installed on the top outer wall of the support rod 18 at the center of the fixed rod 4, and the output shaft of the grinding motor 19 is connected to the grinding cylinder 20.

[0024] A fixed motor 7 is installed on the top outer wall of the fixed rod 4, and the output shaft of the fixed motor 7 is connected to one end of the bidirectional screw 6. An adjusting motor 17 is installed on the outer wall of one end of the rotating rod 13, and the output shaft of the adjusting motor 17 is connected to one end of the adjusting screw 16. After the adjusting screw 16 in the rotating rod 13 rotates, the distance between the grinding motor 19 on the support rod 18 and the spring is adjusted, which is convenient for adjustment and use.

[0025] Both ends of the bidirectional screw 6 are threaded with threaded rods 8, and the other end of the threaded rod 8 is symmetrically welded with an arc plate 9. The outer wall of the inner side of the arc plate 9 is provided with anti-slip strips 10 distributed at equal intervals.

[0027] Working principle: In use, place one end of the spring on the top of the arc plate 9 and adjust the position of the spring end. After starting the fixed motor 7, it drives the bidirectional screw 6 to rotate. The threaded rods 8 at both ends of the bidirectional screw 6 drive the arc plate 9 to move closer together and clamp one end of the spring. At this time, the rotating rod 13 is rotated and adjusted through the connecting hole 14 so that the grinding cylinder 20 on the grinding motor 19 faces one end of the spring. Start the grinding motor 19 and the adjusting motor 17 to drive the adjusting screw 16 and the grinding cylinder 20 to rotate respectively. The rotation of the adjusting screw 16 drives the grinding cylinder 20 to move closer to one end of the spring through the support rod 18. After the grinding cylinder 20 fits one end of the spring, it rotates to grind one end of the spring. Different grinding heads can be used to achieve different effects on one end of the spring, which is convenient for processing both ends of the spring, making it easy to use and reducing the cost of use.
