Abstract
The utility model discloses a connecting rod of a punching machine. The connecting rod comprises a rod body, an upper tilting fillet which is connected to the lower end of the rod body, and a lower bushing seat which is connected with the upper bushing seat through a screw rod, wherein connecting rod tiles are arranged on the upper bushing seat and the lower bushing seat respectively; a gasket is adhered to the back of each connecting rod bushing and is made of a polyurethane material. The gasket which is made of the polyurethane material is adhered to the back of each connecting rod bushing, and generates large elasticity in a power transmission process of a crankshaft and a connecting rod, so that the impact of the crankshaft on the connecting rod tiles is effectively reduced, vibration and noise caused by the impact on the connecting rod bushings are greatly reduced, and the vibration and noise of a machine body are effectively reduced.
Description
Technical field
The utility model relates to a kind of punch press mechanical field, relates in particular to a kind of punch press connecting rod.
Background technique
Punch press is exerted oneself by main motor, drives flywheel, through motions such as clutch driven gear, bent axle (or eccentricity gear) and connecting rods, reach the straight line motion of slide block, and arranging of connecting rod mainly is that circular movement is converted to straight line motion.But can produce bigger noise and vibration when impacting owing to the connecting rod bearing shell on bent axle and the connecting rod, and the vibration that produces can be passed to lathe bed by lower tile mounting base, make the lathe bed vibration and produce bigger noise, the staff is had bigger influence.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of punch press connecting rod that can effectively reduce punch press vibration and noise is provided.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs:
A kind of punch press connecting rod comprises shaft, is connected the tile mounting base of shaft lower end, by the lower tile mounting base that screw rod is connected with tile mounting base, is respectively arranged with connecting rod bearing shell on tile mounting base and the lower tile mounting base, and described connecting rod bearing shell back is adhesive with a pad.
Further setting as such scheme: described pad adopts the polyurethane material.
The beneficial effect that the utlity model has: by be adhesive with the pad of being made by the polyurethane material at the connecting rod bearing shell back, because pad can produce bigger elasticity in bent axle and connecting rod power transmission process, effectively slow down bent axle to the impact of connecting rod bearing shell, greatly reduce the vibration and the noise that produce when impacting connecting rod bearing shell, effectively reduce vibration and the noise of lathe bed.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: shaft 1, tile mounting base 2, lower tile mounting base 3, screw rod 4, connecting rod bearing shell 5, pad 6.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of punch press connecting rod, comprise shaft 1, be connected the tile mounting base 2 of shaft 1 lower end, the lower tile mounting base 3 that is connected with tile mounting base 2 by screw rod 4, be respectively arranged with connecting rod bearing shell 5 on tile mounting base 2 and the lower tile mounting base 3, described connecting rod bearing shell 5 backs are adhesive with a pad 6, and described pad 6 adopts the polyurethane materials.The utility model is by being adhesive with the pad of being made by the polyurethane material 6 at connecting rod bearing shell 5 backs, because pad 6 can produce bigger elasticity in bent axle and connecting rod power transmission process, effectively slow down bent axle to the impact of connecting rod bearing shell 5, greatly reduce the vibration and the noise that produce when impacting connecting rod bearing shell 5, effectively reduce vibration and the noise of lathe bed.
Claims (2)
