Abstract
The utility model relates to a tensioner used for charging tray of double side grinding machine, which consists of a support positioned at one side of the charging tray, trolleys at both ends of the support, a screw at one end of support and a compression spring positioned on the screw, wherein, the support and the grinding wheel are respectively arranged at both sides of the charging tray. With a shape of D, a chain is enwound parts to be machined on the trolley and the charging tray. Having advantages of simple structure, energy-saving, convenient manufacture and maintenance, the utility model tensions the chain by means of spring force.
Description
Technical field
The utility model relates to a kind of tensioning apparatus, especially a kind of charging tray tensioning apparatus that is used for double-ended grinding machine.
Background technology
The charging tray tensioning apparatus of present employed double-ended grinding machine, as shown in Figure 1, its tensioning is by hydraulic-driven, oil cylinder (20) is located at homonymy with emery wheel, need three rollers (22) altogether, one links the both sides of being located at charging tray (9) of two other symmetry with oil cylinder (20), three rollers (22) are isosceles triangle and arrange that chain (8) wraps up the processing parts on three rollers (22) and the charging tray (9) simultaneously.The length of the required chain of this structure (8) is longer, and oil cylinder (20) and emery wheel are located at homonymy, makes troubles for processing and maintenance, its complex structure, and driving is by hydraulic pressure, need expend certain energy.
Summary of the invention
The purpose of this utility model is the charging tray tensioning apparatus of a kind of simple in structure, double-ended grinding machine of saving energy consumption of design.The technical solution of the utility model is so to realize:
A kind of charging tray tensioning apparatus that is used for double-ended grinding machine, comprise charging tray (9), chain (8) and tensioning drive unit, the tensioning drive unit is by the support of being located at charging tray (9) one sides (7), the roller (6) at support (7) two ends, the screw rod (1) of support (7) one ends and compression spring (3) provided thereon are formed, screw rod (1) is arranged vertically with support (7), roller (6) by screw rod (1) one side connects with screw rod (1) by slide block (5), the two ends of compression spring (3) are provided with spring base (2), be provided with a fixed stop (4) between spring base (2) and the support (7), the other end of spring base (2) is provided with tension adjustment nut (23), support (7) and emery wheel (11) place the both sides of charging tray (9) respectively, chain (8) is wrapped in the outside of the processing parts (10) on two rollers (6) and the charging tray (9), is " D " type.
The utility model is to utilize spring force to carry out chain is carried out tensioning, and support and emery wheel place the both sides of charging tray respectively.This use is novel to have simple in structurely, saves energy consumption, processing and characteristics easy to maintenance.
Description of drawings
Accompanying drawing 1 is the structural representation of tensioning apparatus in the prior art;
Accompanying drawing 2 is a kind of structural representations of the present utility model;
Accompanying drawing 3 is another kind of structural representations of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
