Description

Technical Field

[0001] This utility model relates to a spring outer circle grinding device, belonging to the field of spring processing technology. Background Technology

[0002] To ensure a more secure and faster spring installation, the outer circumference of the spring needs to be ground during production. Traditionally, grinding the outer circumference of a spring involves manually holding the spring, which is dangerous and inefficient. Therefore, a dedicated spring outer circumference grinding device has been developed.

[0003] For example, Chinese utility model patent CN213498313U proposes a "spring outer circle grinding machine," which includes a housing. A first motor with its output shaft extending forward is fixedly installed on the left side of the bottom surface of the housing. A pulley is fixedly installed at the end of the output shaft of the first motor. A drive roller located at the lower left of the housing is mounted on the pulley via a belt. A horizontally positioned first electric telescopic rod is fixedly installed on the lower part of the right side wall of the housing. A driven roller is fixedly installed at the left end of the first electric telescopic rod. A second mounting plate and a first mounting plate are symmetrically installed from top to bottom on the left and right side walls of the housing. A second motor with its output shaft pointing downwards is fixedly installed on the upper surface of the first mounting plate. This patent avoids problems such as spring slippage, compression, or stretching during grinding, ensuring grinding quality. Simultaneously, it grinds multiple springs as a whole, ensuring uniform grinding and improving grinding efficiency.

[0004] However, in the aforementioned patents, the positioning of the upper end of the outer circle of the spring to be ground is achieved through the coordinated action of two grinding rollers, a driven roller, a driving roller, and a clamping roller. This method is complex, costly to manufacture, and not easily adopted. Therefore, this utility model proposes a spring outer circle grinding device with a simple positioning structure, low cost, and easy adoption to solve the above problems. Utility Model Content

However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0023] like Figures 1-3As shown, a spring-loaded outer circle grinding device includes a grinding box 1. A set of first cylinders 2 is located at the top of the grinding box 1, with their output ends extending into the grinding box 1. An upper positioning mechanism is fixedly connected to the output ends of the first cylinders 2. A set of second cylinders 3 is located on the right end face of the grinding box 1, with their output ends extending into the grinding box 1. A side positioning mechanism is installed at the output ends of the second cylinders 3. A set of supports 4 is located on the left side of the inner bottom wall of the grinding box 1, with grinding rollers 5 rotatably connected between the supports 4. A driving mechanism for driving the grinding rollers 5 to rotate is also provided inside the grinding box 1. The side positioning rollers 10 are horizontally arranged with the grinding rollers 5. Several upper positioning rollers 8 are located at the upper position between the grinding rollers 5 and the side positioning rollers 10. The upper positioning rollers 8, the grinding rollers 5, and the side positioning rollers 10 form a triangular three-point positioning structure.

[0024] In the above technical solution, multiple upper positioning rollers 8 are rotatably connected between the arc plates 7 at both ends of the bottom of the first U-shaped frame 6 and the side positioning rollers 10 are rotatably connected between the second U-shaped frame 9. Together with the grinding rollers 5 rotatably connected on the bracket 4, a three-point positioning structure is formed. The inner circles of the three are the outer circles of the spring to be ground. The positioning structure of the spring to be ground is simple, has low cost, and is easy to promote.

[0025] In this utility model, the upper positioning mechanism includes a first U-shaped frame 6, which is fixedly connected to the bottom of the output end of a set of first cylinders 2. Both ends of the bottom of the first U-shaped frame 6 are fixedly connected to arc-shaped plates 7. A plurality of upper positioning rollers 8 are provided between the arc-shaped plates 7, and both ends of the plurality of upper positioning rollers 8 are rotatably connected to the arc-shaped plates 7 respectively.

[0026] In the above technical solution, by rotating and connecting multiple upper positioning rollers 8 between the arc plates 7, when the spring to be polished is placed above the grinding roller 5 and the side positioning roller 10, the first cylinder 2 is activated, driving the first U-shaped frame 6 and the arc plate 7 to move downward. When the upper positioning roller 8 moves to be tangent to the outer tangent surface of the spring to be polished, it can be used to position the upper part of the spring to be polished with the assistance of the side positioning roller 10 and the grinding roller 5.

[0027] In this utility model, the side positioning mechanism includes a second U-shaped frame 9, which is fixedly connected to the end of the output end of a set of second cylinders 3, and a side positioning roller 10 is rotatably connected inside the second U-shaped frame 9.

[0028] In the above technical solution, by setting the side positioning roller 10, when it is necessary to place the spring to be polished, the second cylinder 3 is started, pushing the second U-shaped frame 9 towards one end of the polishing roller 5, and the polishing roller 5 can lift the lower end of the spring to be polished.

[0029] In this utility model, the driving mechanism includes a mounting plate 11, which is fixedly connected to the left side wall inside the grinding box 1. A motor 12 is provided on the top of the mounting plate 11. A first pulley 13 is sleeved on the output shaft of the motor 12. A belt 14 is sleeved on the first pulley 13. A second pulley 15 is driven to the first pulley 13 through the belt 14. The second pulley 15 is sleeved on the roller shaft of the grinding roller 5.

[0030] In the above technical solution, by setting a motor 12 on the mounting plate 11, the motor 12 can drive the first pulley 13 to rotate when it starts. The rotation of the first pulley 13 can drive the second pulley 15 to rotate via the belt 14, which in turn can drive the grinding roller 5 to rotate and grind the spring that needs to be ground.

[0031] In this utility model, a discharge port 16 is provided below the second cylinder 3 on the right side of the grinding box 1. An arc-shaped guide plate 17 is provided inside the grinding box 1. One end of the guide plate 17 is located below the grinding roller 5, and the other end of the guide plate 17 is located below the discharge port 16 and is fixedly connected to the inner wall of the grinding box 1. The grinding box 1 is provided with a box door 18.

[0032] In the above technical solution, by setting the discharge port 16 and the guide plate 17, after the spring is polished, the first cylinder 2 and the second cylinder 3 retract, driving the upper positioning roller 8 and the side positioning roller 10 away from the polishing roller 5. The spring loses its positioning and falls from the gap between the polishing roller 5 and the guide roller onto the guide plate 17, and finally falls out of the polishing box 1 from the discharge port 16, which facilitates the collection of the spring after polishing. By setting the box door 18, it is convenient to place the spring to be polished when it is open, and closing the box door 18 during polishing can prevent the sparks from polishing from injuring the workers.

[0033] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
