Abstract
The invention relates to an anti-disengaging device for connection between a drive cylinder and a sideway-drawn inclined wedge. The anti-disengaging device comprises the sideway-drawn inclined wedge, a clamping plate, a connecting block, the drive cylinder and a drive cylinder piston rod. The sideway-drawn inclined wedge and the clamping plate are fixedly connected. The connecting block and the drive cylinder piston rod are matched through threads. The connecting end of the sideway-drawn inclined wedge and the clamping plate is provided with a T-shaped boss. A groove is formed in the clamping plate. The transverse edge of the T-shaped boss and one end of the connecting block are arranged in the groove. The anti-disengaging device effectively solves the problem that the drive cylinder and the sideway-drawn inclined wedge are disengaged in the moving process, and safe and stable work of the sideway-drawn inclined wedge and the drive cylinder is ensured.
Description
Technical field
The invention belongs to Press Tools for Automobiles field, specifically refer to that a kind of cylinder and side of driving take out the locking device that wedge is connected.
Background technology
At present, in automobile large stamping die, it is very common that the gusset of for example automobile, tail-gate outside plate side are taken out the use of wedge, and side is taken out type of drive that wedge is conventional for using large-scale air cylinder driven.Drive cylinder and side to take out wedge and be connected that steady operation is particularly important afterwards.
In prior art, side is taken out wedge and the connected mode that drives cylinder, and what generally adopt is the mode of screw fastening.As Fig. 1, side is taken out wedge 1, clamp 2, and contiguous block 3, drives cylinder 4, drives cylinder piston rod 5.Side is taken out wedge 1 and clamp 2 use screw fastenings, drives cylinder piston rod 5 and contiguous block 3 use threaded engagement, and contiguous block 3 is stuck in the U-lag of contiguous block clamp 2 from top.
A shortcoming of prior art is: clamp 2 and side are taken out after wedge 1 use screw fastening, have the possibility of screw loosening.
Another shortcoming is: after contiguous block 3 and driving cylinder piston rod 5 use threaded engagement, have equally the situation of thread looseness, will cause contiguous block 3 and drive cylinder to stretch relatively rotating of piston 5, thereby whole mechanism is unstable in the course of the work; Also can relatively rotating of contiguous block 3 and clamp 2.
Summary of the invention
The invention provides a kind of cylinder and side of driving and take out the locking device that wedge is connected, this device mainly solves the loosening situation of threaded engagement that drives cylinder and side to take out to occur in wedge connection procedure, a kind of locking mode is provided, and the present invention is simple in structure, working stability, installing/dismounting is easy to realize.
The present invention is realized by following technical scheme:
Drive cylinder and side to take out the locking device that wedge is connected, include side and take out wedge, clamp, contiguous block, driving cylinder and piston rod; Described side is taken out wedge and is fixedly connected with clamp; Described contiguous block passes through threaded engagement with driving cylinder piston rod; Described side takes out wedge and clamp link is provided with T-shaped boss, in described clamp, is provided with groove; In described groove, be provided with one end of horizontal edge and the contiguous block of T-shaped boss.
Described locking device is also provided with split pin, and described split pin is through contiguous block and drive cylinder piston rod, for preventing contiguous block and driving relatively rotating of cylinder threaded engagement.
Described clamp and side are taken out wedge and are connected side and are set to hatch frame, and described opening is communicated with groove, on the dual-side of opening, is provided with screwed hole, takes out the screw of wedge and clamp for fixation side is set.
Described clamp is connected side with contiguous block be U-shaped groove, and the external diameter of described contiguous block and clamp link is greater than the width of U-shaped groove.
The axial vertical cross-section of described contiguous block is I-shape construction, is provided with at least two relative planes at middle axial region, for preventing relatively rotating between contiguous block and clamp.
The horizontal edge of described T-shaped boss and one end of contiguous block are arranged in groove by interference fit.
The invention has the beneficial effects as follows:
The invention provides a kind of cylinder and side of driving and take out the locking mode of the one being connected between wedge, effectively solved and driven cylinder and side to take out the loosening situation that wedge occurs in motion process, guaranteed that side takes out wedge and drive the work of cylinder safety and stability.
