Description

Technical Field

[0001] The utility model belongs to the technical field of sanding machines, and in particular relates to a driving connection device for a sanding machine. Background Art

[0002] Sanding machines are widely used in the fields of wood, metal, plastic and glass processing. They can grind the surface of products to remove burrs, flaws, etc., making the surface smoother and brighter.

[0003] At present, the sanding machine uses the friction of the motor's self-rotation to stop after sanding. It takes a long time from the beginning of stopping to complete rest, and the purpose of rapid stopping cannot be achieved. Moreover, the driving motor used in the sanding machine has high power and high speed, and it takes longer to rely on the natural stop of the motor. In addition, there is also a brake mechanism installed on the motor spindle to achieve rapid braking, but this is easy to cause damage to the motor spindle and shorten the service life. Utility Model Content

[0004] The purpose of the utility model is to solve the above technical problems existing in the prior art and to provide a sanding machine driving connection device to overcome the shortcomings of the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a sanding machine driving connection device, which includes a universal joint for driving connection; one end of the universal joint is drivingly connected to the driving motor, and the other end is drivingly connected to the grinding roller;

[0006] A brake disc is provided at one end of the universal joint close to the driving motor, and the brake disc is fastened to the universal joint via a flange; a brake caliper fixedly connected to the main frame is provided at one side of the brake disc.

[0007] Furthermore, a coupling is provided on the side of the brake disc facing the drive motor.

[0008] The utility model installs a brake disc on the universal joint, which changes from the previous direct braking of the motor main shaft to the current braking of the universal joint, which can protect the motor main shaft from damage and extend the overall service life. The brake disc is fastened to the universal joint through the flange plate, which is convenient for disassembly and assembly, improves the efficiency of replacement, and does not affect normal production operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural schematic diagram of the utility model.

[0010] In the figure, 1 is a universal joint, 2 is a flange, 3 is a brake disc, and 4 is a coupling. DETAILED DESCRIPTION

[0011] Reference Figure 1The utility model discloses a driving connection device for a sanding machine, which comprises a universal joint 1 for driving connection; one end of the universal joint 1 is drivingly connected to a driving motor, and the other end is drivingly connected to a grinding roller;

[0012] A brake disc 3 is provided at one end of the universal joint 1 close to the driving motor, and the brake disc 3 is fastened to the universal joint 1 via a flange 2; a brake caliper fixed to the main frame is provided at one side of the brake disc 3.

[0013] Furthermore, a coupling 4 is provided on the side of the brake disc 3 facing the drive motor.

[0014] The utility model installs a brake disc on the universal joint, which changes from the previous direct braking of the motor main shaft to the current braking of the universal joint, which can protect the motor main shaft from damage and extend the overall service life. The brake disc is fastened to the universal joint through the flange plate, which is convenient for disassembly and assembly, improves the efficiency of replacement, and does not affect normal production operation.
