Embodiment Construction

[0056] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0057] The center of the grinding section 1 has an accessory tool installation hole, and the accessory tool installation hole can be a round hole or a figure 1 There are several snap-fitting holes 11 that are equidistant and circumferentially distributed around. In this embodiment, the technical solution of this embodiment is described by using the abrasive slice 1 as an accessory tool, but this cannot limit the scope of protection of the present invention.

[0058] Such as Figure 2 to Figure 12 As shown: this embodiment discloses a quick locking device for accessory tools: it includes a locking clamping part, a drive transmission part and a support part 3, the drive transmission part include...

Abstract

The invention discloses an accessory tool rapid locking device and a locking method. The accessory tool rapid locking device comprises a locking clamping part, a driving conduction part and a supporting part, wherein the driving conduction part comprises a lower pressing plate and an upper pressing plate, and one end of the upper pressing plate is connected to the supporting part; the locking clamping part is arranged in the supporting part and extends into the upper pressing plate; when the auxiliary tool is installed between the lower pressing plate and the upper pressing plate, the locking clamping part drives the lower pressing plate and the upper pressing plate to clamp the auxiliary tool, and the lower pressing plate and the upper pressing plate are connected through a shape locking structure capable of transmitting torque. A first protrusion matched with the accessory tool installation hole is arranged at one end of the lower pressing plate, and when an accessory tool is installed between the lower pressing plate and the upper pressing plate, the first protrusion is inserted into the accessory tool installation hole. Torque can be transmitted through shearing force, so that the required clamping force is small, and the operation of the rapid clamping operation part is more labor-saving. Locking and loosening can be achieved without the help of additional tools, and the device can be matched with various auxiliary tools in the prior art.

Description

technical field [0001] The invention relates to the technical field of tool connection devices, in particular to a quick locking device and a locking method for an accessory tool. Background technique [0002] A quick clamping device is known for a portable power tool, in particular an angle grinder, having at least one output shaft that can be driven in rotation, the quick clamping device has at least one snap-in section, which can be inserted into the accessory The tool is fixed on the form-locking section of the upper pressing plate by means of a separated lower pressing plate, so that it can receive power torque transmission and complete corresponding work. [0003] When the clamping device in the prior art is in the clamping state, the clamping device directly acts on the periphery of the mounting hole of the accessory tool, and the friction force generated by extrusion transmits torque to the accessory tool, for example, ordinary threads are often used. It is fixed by...
