Abstract
The present invention discloses a control device for a slide block, which belongs to the technical field of machinery. The present invention particularly relates to a mechanism for controlling the movement of a slide block. The control device for a slide block comprises a base and a slide block, wherein the slide block is placed on the base; the upper part of the slide block is provided with a control block which can move up and down in the direction perpendicular to the sliding direction of the slide block. A bent control strip is fixed on the control block which is provided with a gap for the control strip to be inserted downward, and the gap is a little wider than the control strip. The slide block is provided with two pulleys in parallel, and the gap between the two pulleys is a little wider than the strip. The control block moves up and down to drive the slide block to slide forwards and backwards. The control strip with specific bent shape is selected to easily make the slide block flexibly in one of the three states of an advancing state, a backing state and a stopping state according to needs, so that the present invention has convenient use and high work efficiency.
Description
Technical field
The invention belongs to field of mechanical technique, particularly a kind of mechanism that is used to control slide block movement.
Background technique
Slide block has a wide range of applications on devices such as lathe or machine die.The slip of slide block normally realizes by a control gear.At present the structure of slide block control gear commonly used as shown in Figure 5, slide block 2 is positioned on the pedestal 1, and a controll block 4 is arranged above slide block 2, contacts by the inclined-plane between controll block 4 and the slide block 2.Utilize moving down of controll block 4, make slide block 2 to front slide.In the ordinary course of things, because moving down of controll block 4 is a process at the uniform velocity, therefore slide block 2 can only be in to a kind of state of front slide when work.
After the end of sliding, controll block 4 rises, and also need make slide block 2 return initial position by the elastic force of spring 6.
On the other hand, because controll block 4 is to rely on contacting of inclined-plane to realize with transmission between the slide block 2, when work sliding friction is arranged, its surface friction drag is bigger, the energy consumption that makes whole device greatly, inefficiency.
Summary of the invention
To the objective of the invention is in order addressing the above problem, a kind of slide block control gear of novel structure to be provided, make to adopt the sliding mode of this device rear slider have multiple, control flexibly and when working resistance less.
Purpose of the present invention can realize by following technical proposal: the control gear of this slide block comprises a pedestal and a slide block, slide block is positioned on the pedestal, and can slide along pedestal under external force, it is characterized in that, a controll block is arranged on the top of slide block, controll block can move up and down along the glide direction perpendicular to slide block, fixing a control strip on the controll block, control strip is crooked shape, the gap of inserting downwards for control strip is arranged, and this gap is slightly greater than the width of control strip on slide block.
In the control gear of above-mentioned slide block, two pulleys that be arrangeding in parallel on the described slide block have slightly the gap greater than the control strip width between two pulleys.
In use, control strip inserts between these two pulleys, and the edge of control strip contacts with two pulleys.The control gear of this slide block is exactly to utilize moving up and down of controll block, is slided in control strip drive slide block front and back.Here, pulley is to play the effect that reduces the frictional force that control strip contacts with slide block, makes control strip can drive the slide block slip flexibly.
After adopting the control gear of this slide block, slide block move forward and backward with control strip crooked shape directly related.Therefore, by selecting the control strip of specific bent shapes for use, when control strip at the uniform velocity moves down, be easy to that slide block is in as required flexibly and advance, retreat or stop a kind of in three kinds of states, and can repeat to be in a kind of state wherein, use very convenient.Simultaneously, owing to be provided with pulley between control strip and slide block, utilize the force of rolling friction features of smaller, resistance is very little when making slide block work, high working efficiency.

Embodiment
As shown in Figure 1, the control gear of this slide block comprises parts such as pedestal 1, slide block 2, pulley 3, controll block 4 and control strip 5.In the present embodiment, pedestal 1 is provided with guide rail 11, and slide block 2 is embedded in the guide rail 11 of pedestal 1.Therefore, under external force, slide block 2 can slide along guide rail 11 front and back.
A controll block 4 is arranged directly over slide block 2, a control strip 5 is arranged on the controll block 4, control strip 5 is vertical fixing bottoms in controll block 4.Obviously, controll block 4 can drive control strip 5 and moves up and down.
As shown in Figure 2, two pulleys 3 are arranged on the slide block 2, pulley 3 is that secured in parallel is on slide block 2.Pulley 3 can rotate.Space greater than control strip 5 width is arranged between two pulleys 3 slightly.When control strip 5 inserted between two pulleys 3, the edge of control strip 5 contacted with pulley 3.Along with moving of control strip 5, pulley 3 also rotates.
Because pulley 3 is edges of being close to control strip 5, so the curved shape of control strip 5 has determined the movement direction of pulley 3, has also just determined the glide direction of slide block 2.
As shown in Figure 3, when control strip 5 did not insert pulley 3, slide block 2 was in initial position.As shown in Figure 4, along with moving down of controll block 4, control strip 5 inserts between two pulleys 3, and slide block 2 is slided by the bending direction of control strip 5.In the present embodiment, slide block 2 will be in sliding mode to the right earlier along with moving down of control strip 5, and sliding mode left is in slack state at last again.
When controll block 4 moved up post-equalization, slide block 2 slided by opposite mode, gets back to initial position at last.
Because control strip 5 contact with pulley 3, friction between the two is rolling friction, its surface friction drag seldom, so it is also more laborsaving to pass through the slip of controll block 4 drive slide blocks 2 in this control gear, the entire mechanism energy consumption is little, high working efficiency.
