TW201741064A - Single-side clamping device comprising first and second slope surfaces that are caused to move relative to each other to selectively fix and release a tool - Google Patents

Abstract

A single-side clamping device is disclosed. When a bolt is screwed to advance with respect to a reference platform, an elastic element is compressed by first and second stop sections that are opposite to each other. A second clamping surface of an operation block is constrained by a second wall and under this condition, a second slope surface is shifted and moved leftward with respect to a first slope surface so that a tool can be clamped and fixed between a first clamping surface and a first wall. When the bolt is screwed to retract with respect to the reference platform, the elastic element that was previously compressed by the first and second opposite stop sections generates a restoration spring force. Since the second clamping surface of the operation block is constrained by the second wall, the second slope surface, under this condition, is shifted and moved rightward with respect to the first slope surface so as to cause the operation block to move upward, and the force that clamps and fixes the tool between the first clamping surface and the first wall is removed and released so as to allow the tool to be removed.

Description

Single side clamping device

The present invention relates to a tool holding device, and more particularly to a one-side clamping device for holding a tool such as a turning tool on one side.

The conventional unilateral processing fixture, as shown in China's Announcement Nos. M266131 and 37483, includes a base, a fixed cymbal, and a plurality of movable cymbals; a sliding slot is formed in the center of the base, and slide rails are formed on both sides of the sliding slot respectively. The fixed cymbal is placed on the two sliding rails of the base, one end of which serves as a clamping surface, and the lower part is coupled to the first sliding block through a bolt, and the first sliding block is received in the sliding groove of the base, so that the fixing cymbal is fixed on the base The movable cymbal includes a first second oblique block; the first inclined block has a first inclined surface at one end, and the other end serves as a clamping surface, and the second sliding block is coupled to the lower portion through the bolt, and the second sliding block is accommodated in the sliding of the base In the slot, the first oblique block is fixed on the base; the second inclined block is provided with a second inclined surface abutting against the first inclined surface, and the other end is used as a clamping surface, and a third sliding block is coupled to the lower portion through the bolt, The third sliding block is received in the sliding groove of the base; when the single-side machining fixture is used, the workpiece can be placed between the fixed cymbal and the second oblique block, and each of the first oblique block and the second oblique block Between, then use the tool to lock the bolt of the second slider down to make the first bevel Generating a second component force ramp, causes the second inclined block clamped workpiece.

However, when the bolt of the second inclined block is loosened (that is, when the workpiece is to be unloaded), the second inclined block is often caught between the workpiece and the first inclined surface of the first inclined block due to the inclined relationship, resulting in the finished workpiece. Can not properly disengage the fixture; in addition, before the second diagonal block does not clamp the workpiece, the capacity It is easy to slide down due to the weight. After the above-mentioned knot function, the size of the jaw between the fixed jaw and the second oblique block is reduced, the operator must hold the second oblique block with one hand, and the workpiece is placed by the other hand.
