Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically a device for deburring the sheet metal back panel of a television set. Background Technology

[0002] Televisions are common home appliances. The sheet metal back panels of televisions are generally produced through stamping and other methods. This production process inevitably results in burrs on the edges of the sheet metal back panels, making the edges sharp and burr-prone, posing a safety hazard and potentially injuring users or production personnel. This also fails to meet production and usage requirements. Therefore, it is often necessary to grind the sheet metal back panels to remove the burrs. Currently, the grinding of burrs on sheet metal back panels is generally done manually or with ordinary grinding machines. However, manual grinding is inefficient, and grinding machines can easily lead to incomplete removal of burrs at the corners or small bends of the panel, failing to meet user needs.

Detailed Implementation

[0015] 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.

[0016] Please see Figures 1 to 2 The present invention provides the following technical solution:

[0017] A deburring device for a TV sheet metal back panel includes a main body 1, a clamp 2, and a grinding assembly. The clamp 2 is installed on the main body 1. The main body 1 is a handheld grinder. Both the main body 1 and the clamp 2 are existing mature products that users can purchase as needed. The grinding assembly is installed on the clamp 2, so that the main body 1 can drive the grinding assembly to rotate through the clamp 2. The grinding assembly includes a fixing module 3, a grinding module 4, and an adjustment module 5. The fixing module 3 is installed on the clamp 2 and is used to install the grinding module 4. The adjustment module 5 is installed between the grinding module 4 and the fixing module 3 and is located at the end of the grinding module 4. The adjustment module 5 is used to adjust the grinding module 4.

[0018] The fixing module 3 includes a clamping rod 31, a limiting plate 32, and a splined shaft 33. The clamping rod 31 is adapted to the chuck 2 and is installed at the chuck 2. The end of the clamping rod 31 is provided with a limiting plate 32, and the end of the limiting plate 32 away from the clamping rod 31 is provided with a splined shaft 33. The limiting plate 32 is used to limit the grinding module 4, and the splined shaft 33 is used to install the grinding module 4 so that the grinding module 4 can rotate with the splined shaft 33. The splined shaft 33 is coaxially arranged with the clamping rod 31.

[0019] The grinding module 4 includes a first grinding wheel 41, a second grinding wheel 43, and a third grinding wheel 45, all of which are slidably mounted on a spline shaft 33 via spline grooves, allowing them to rotate synchronously with the spline shaft 33. The third grinding wheel 45 is installed between the first grinding wheel 41 and the second grinding wheel 43, so that the first grinding wheel 41 and the second grinding wheel 43 are respectively clamped on both sides of the edge of the sheet metal back plate, and the third grinding wheel 45 abuts against the edge end of the sheet metal back plate. The three grinding wheels work together to grind the rough edges at the edge of the sheet metal back plate. The first grinding wheel 41 and the second grinding wheel 43 are respectively provided with a first movable groove 42 and a second sliding groove. The third grinding wheel 45 is adapted to the first movable groove 42 and the second movable groove 44, and both ends of the third grinding wheel 45 are respectively inserted into the first movable groove 42 and the second movable groove 44, so that the position between the first grinding wheel 41 and the second grinding wheel 43 is adjustable while preventing the third grinding wheel 45 from disengaging from the first grinding wheel 41 and the second grinding wheel 43.

[0020] The ends of the first grinding wheel 41 and the second grinding wheel 43 near the third grinding wheel are both arc-shaped, so that the gap between the first grinding wheel 41 and the second grinding wheel 43 gradually decreases from their edges to their centers.

[0021] The adjustment module 5 is sleeved on the spline shaft 33. The adjustment module 5 includes a first pad 51, an adjustment spring 52, a second pad 53, and an adjustment sleeve 54. The first pad 51 and the second pad 53 are respectively provided at both ends of the adjustment spring 52. The adjustment spring 52 can push the second grinding wheel 43 towards the first grinding wheel 41. The first pad 51 and the second pad 53 work together to enable the adjustment spring 52 to push the second grinding wheel 43 better. The first pad 51 abuts against the end of the second grinding wheel 43, and the second pad 53 abuts against one end of the adjustment sleeve 54. The adjustment sleeve 54 is sleeved on the spline shaft 33. The length of the adjustment sleeve 54 can be replaced as needed to adjust the position of the adjustment spring 52, thereby adjusting the distance between the first grinding wheel 41 and the second grinding wheel 43. A fastening bolt 55 is installed at the end of the spline shaft 33. The fastening bolt 55 abuts against the other end of the adjustment sleeve 54. The fastening bolt 55 can prevent the grinding module 4 and the adjustment module 5 from disengaging from the spline shaft 33.

[0022] The specific implementation process is as follows:

[0023] When using the deburring device for the sheet metal back panel of this TV, first determine the thickness of the sheet metal back panel, then replace the appropriate adjusting sleeve 54 so that the position between the first grinding wheel 41 and the second grinding wheel 43 matches the thickness of the sheet metal back panel, and then fix the fastening bolt 55 to the end of the spline shaft 33.

[0024] When this device is working, the main body 1 drives the grinding assembly to rotate through the chuck 2. The spline shaft 33 then drives the first grinding wheel 41, the second grinding wheel 43, and the third grinding wheel 45 to rotate synchronously. Then, the user can insert the sheet metal back plate between the first grinding wheel 41 and the second grinding wheel 43. Under the action of the adjusting spring 52, the first grinding wheel 41 and the second grinding wheel 43 are clamped on both sides of the edge of the sheet metal back plate, while the third grinding wheel 45 abuts against the end of the edge of the sheet metal back plate. Through the coordinated action of the three grinding wheels, the rough edges and burrs on the edge of the sheet metal back plate can be ground.

[0025] The deburring device for the sheet metal back panel of this TV uses the coordinated action of the grinding wheels in the grinding module 4 to clamp both sides of the sheet metal back panel of the TV and grind both sides and the ends of the edge of the sheet metal back panel. This can efficiently and effectively grind the burrs on the sheet metal back panel. At the same time, the distance between the first grinding wheel 41 and the second grinding wheel 43 can be adjusted by the adjustment module 5, so that the grinding module 4 can be adapted to sheet metal back panels of different thicknesses.
