Abstract

A horizontal installation stopping cylinder provided with a buffer is arranged at the left end of a base; a stopping bracket is positioned at the upper part of the base; a shaft is arranged at the left end of the base and connected with the stopping bracket; a hydraulic buffer is arranged at the middle part of the stopping bracket; a lever is arranged at the right end of the stopping bracket through a lever shaft; the lower end of the lever is pressed on an outer end of a movable shaft of the buffer; two stopping rollers are arranged at the upper end of the lever; an offset spring is arranged on the lever shaft; and one end of the offset spring is pressed on the upper side of the movable shaft of the buffer. The horizontal installation stopping cylinder provided with the buffer can reliably stop a moving heavy workpiece and can enable the moving heavy workpiece to stop slowly when used in a production line, and the impulsive force cannot act on the cylinder, so that the purpose of stopping the heavy workpiece reliably can be achieved. The horizontal installation stopping cylinder can absorb the impulsive force so as to prevent the cylinder from being damaged.

Description

The level of band buffer is installed and is stopped cylinder

Technical field

The utility model belongs to the pneumatics field, and the level of the pneumatic arresting stop one band buffer that uses on particularly a kind of production line is installed and stopped cylinder,

Background technique

On various automatic production lines, for being stopped at each station, pallet on the production line and workpiece carry out operation, need to use stopper that it is blocked, mostly the stopper that uses on the production line is that vertical installation stops cylinder at present, owing to stop that the impact force that produces in the process finally still acts on the cylinder column, when coming simultaneously, heavier workpiece or a plurality of pallet be easy to damage stop cylinder, so be not suitable for stopping heavy workpiece; The stopper that is fit to stop heavy workpiece is also arranged at present, this stopper generally drives a baffle plate knee-action by cylinder, reaches the purpose that stops workpiece, but can produce very big impact in the heavy workpiece stopped process, all unfavorable to equipment like this with the workpiece that is blocked, be easy to cause damage.

The model utility content

The utility model purpose provides a kind of cylinder that stops of the band buffer that is fit to stop heavy workpiece, in order to overcome above shortcoming, this cylinder that stops stops the workpiece of motion by a cover countercheck mechanism, barrier force does not act on the cylinder column, absorbs the impact energy that produces in the stopped process with buffer simultaneously.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of level with buffer is installed and is stopped cylinder, it is characterized in that: cylinder is contained in the base left end, stop support has an axle to connect stop support at the base left end above base, and hydraulic bjuffer is contained in the middle of the stop support, lever is contained in the stop support right-hand member by lever shaft,, the lever lower end is pressed on the axle outer end of work of buffer, and lever upper end has two to stop roller, Returnning spring is contained on the lever shaft, and Returnning spring one end is pressed in the axle upside of living to buffer.

The utility model characteristics:

The level of this band buffer is installed and is stopped that cylinder uses on production line, can reliably stop the heavy workpiece of motion, and the heavy workpiece of motion is slowly stopped, thereby and impact force can not act on the purpose that realizes reliably stopping heavy workpiece on the cylinder.Absorbing impulse force avoids cylinder to damage.

Embodiment

A kind of level with buffer is as shown in Figure 1, 2 installed and is stopped cylinder, cylinder 1 is contained in base 2 left ends, stop support 6 is above base 2, there is an axle 12 to connect stop support at base 2 left ends, hydraulic bjuffer 11 is contained in the middle of the stop support 6, lever 9 is contained in stop support 6 right-hand members by lever shaft 7, lever 9 lower ends are pressed on live axle 13 outer ends of buffer, the lever upper end has two to stop roller 10, Returnning spring 8 is contained on the lever shaft 7, and Returnning spring one end is pressed in live axle 13 upsides to buffer.

In stop mechanism, use buffer to absorb impact energy; Use leverage to prevent that workpiece from being knocked in the block piece; The cylinder level is installed, and barrier force does not act on the cylinder; Can realize a plurality of cylinder mechanical linkages that stop.

The support that plays barrier effect is contained on the base, and this support one end links to each other with base, and can adorn a hydraulic bjuffer in the middle of the support around its coupling shaft rotation, and the other end is adorned a lever, and the lever upper end is a roller, and the lower end is pressed on the buffer; One end of base is adorned a cylinder, the cylinder rod end has one group of roller, when cylinder column ejects or returns by slope effect with support jack-up or fall, if support below lose barrier effect, workpiece can freely pass through, as support up, when workpiece by the time just can be blocked cylinder lever block, lever rotates around axle, and impact force is passed to buffer, and buffer is slowly depressed sponges impact energy.

Support roller moved right in the guiding groove under the base when cylinder ejected, the jacking roller is then with stop support jack-up, like this when workpiece passes through, the roller that stops on the lever can block workpiece, in blocking the process of workpiece, buffer is pressed in the rotation of lever distaff thick stick axle, the impact energy of workpiece can be sponged like this, and workpiece is slowly stopped; Roller below driving during the cylinder column withdrawal is to left movement, and stop support falls, and workpiece can freely pass through (see figure 3).

Owing in countercheck mechanism, used leverage, can prevent effectively that workpiece is blocked cylinder and knocks over, Returnning spring can make lever keep vertical state.

The utility model both can one uses separately, also can a plurality ofly link, and in two interlock modes as shown in Figure 4, second buffer 15 descends when first buffer 14 rises.Second cylinder rises when first cylinder descends.
