Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a belt type grinding device. Background Art

[0002] Grinding machines are mainly used for surface treatment of workpieces, such as polishing and grinding of workpiece surfaces. For surface treatment of workpieces, lathes or handheld grinders are usually used for grinding, but this grinding method is usually suitable for grinding the surface of products. For cylindrical products, the existing grinding equipment has a small contact area with the product surface and low grinding efficiency. In addition, during manual grinding, the force control cannot guarantee stability, resulting in inconsistent surface quality after grinding. When using mechanical arms and other equipment to hold the grinding equipment for grinding, the wear or loosening of the grinding wheel or grinding belt will cause the contact pressure with the product surface to decrease, affecting the grinding accuracy. Therefore, how to increase the grinding stability and thus ensure the grinding accuracy is a problem that technicians in this field need to consider. Utility Model Content

[0005] Preferably, the force control device is rotatably connected to a first bracket and a second bracket, and the first bracket and the second bracket are both connected to the force control device via an elastic element, so that the ends of the first bracket and the second bracket away from the force control device tend to move away from each other.

[0006] Preferably, the first pulley is connected to the first bracket, and the second pulley is connected to the second bracket;

[0007] The first bracket and the second bracket are connected to the adjustment end of the force control device through a connecting plate.

[0008] Preferably, both the first bracket and the second bracket are provided with a limiting rod, and the limiting rod passes through the first bracket and the second bracket at an angle relative to the length direction of the first bracket and the second bracket.

[0018] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0019] like Figure 1-3As shown, the utility model is applied to the grinding of the rounded corners of the outer wall of a tubular product or a product with rounded corners. The grinding device is installed on a mechanical arm through a mounting seat, and the mechanical arm drives the grinding device so that the grinding belt between the first bracket and the second bracket approaches and contacts the product. When the approach continues, the first bracket and the second bracket respectively rotate and approach along the connection between them and the connecting plate, and the grinding belt covers part of the surface of the product to increase the grinding area; the grinding device can also be fixedly mounted on the machine, and the circular tubular product is manually held to contact the grinding belt for grinding. In the above two grinding methods, when grinding, the force control device is adjusted in real time based on the preset pressure value according to the pressure change between the product and the grinding belt 8 to ensure that the pressure value between the product and the grinding belt 8 is always stable. Specifically, a belt grinding device includes a mounting seat 1, and a driving device 2 and a force control device 3 are connected to the mounting seat 1. The adjusting end of the force control device 3 is connected to the first bracket 5 and the second bracket 6 through the connecting plate 4, and the first bracket 5 and the second bracket 6 are both connected to the connecting plate 4 through an elastic element (not shown in the figure), so that the first bracket 5 and the second bracket 6 have a driving force to rotate away from each other. Among them, the elastic element can be a torsion spring connected to the connection between the first bracket 5 or the second bracket 6 and the connecting plate 4; or it can be a common spring connected between the first bracket 5 and the second bracket 6, so that the two have a driving force to move away from each other.

[0020] The fixed end of the force control device 3 is connected to the mounting base 1, and the driving device 2 is connected to one side of the mounting base 1 close to the fixed end of the force control device 3. The driving device 2 is connected to a third pulley 21, which can drive the third pulley 21 to rotate. The driving device 2 can be a servo motor or other devices capable of driving rotation.

[0021] The first bracket 5 and the second bracket 6 are connected to the first pulley 51 and the second pulley 61 at one end away from the connecting plate 4 respectively. The grinding belt 8 is arranged around the first pulley 51, the second pulley 61 and the third pulley 21 and forms a triangle.

[0022] In order to avoid excessive rotation of the first bracket 5 and the second bracket 6 during grinding, which may cause interference between the grinding belt 8 and the connecting plate 4 or interference between the first bracket 5 and the second bracket 6, a limit rod 7 is provided on each of the first bracket 5 and the second bracket 6, and the limit rod 7 is inclined relative to the length direction of the first bracket 5 and the second bracket 6 and penetrates the first bracket 5 and the second bracket 6. When the first bracket 5 and the second bracket 6 rotate close to each other, the end of the limit rod 7 protruding from the first bracket 5 or the second bracket 6 contacts the connecting plate 4, so that the first bracket 5 and the second bracket 6 cannot continue to rotate, thereby achieving the limit of the two.

[0023] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
