Abstract
The utility model relates to a bidirectional rolling torsion wrench for screwing the threaded fasteners with torsion requirements. The utility model is characterized in that a lever is arranged on the flat inner wall point of a casing, and lower end of the lever is deflected to one side in the casing. The utility model generates loud signal sound with obvious idle sliding feeling while in work. The inner parts of the grooves of the opposite directions of the upper part and the lower part of a sliding block are respectively provided with a rolling wheel. The friction between the sliding block and the casing is changed from sliding friction to rolling friction. The precision of the torque value and the stability of the torque value of wrenches are improved.
Description
The utility model is a kind of torque spanner that is used to screw the threaded fastener that moment requires, when arriving required moment values, the spanner output torque can send the message of " clatter ", and, the actual suffered fastening force of securing member is consistent with the fastening force that requires to set with significantly feel vibration.
Existing torque spanner, because of the slide block external form is a cylinder, slide block and lever lower end all are contained in the circular position of housing, and the lever lower end is in the centre position of housing, cause lever lower end and inner walls bump distance less than normal, thereby spanner work the time to send the sound of signal less, and the feel vibration is not obvious.The operator is difficult to discover the signal that spanner sends when using in the working environment big at noise, that vibration is big.During spanner work, lever swing is done moving axially with respect to housing by contiguous block compressing slide block, keep sliding friction between slide block and the inner walls, frictional force is bigger, has influenced the precision of wrench torque value and the stability of moment (being the indicating value repeatability precision).
The utility model is intended to overcome above-mentioned shortcoming, has designed that a kind of novel message is loud, feel is obvious, keeps the bidirectional rolling formula torque spanner of rolling friction between slide block and the housing.
The utility model mainly is made up of parts such as housing, lever, contiguous block, slide block, roller, spring washer, springs.The spanner hull shape is last flat circle down.The top of lever, slide block all is loaded on the flat inside of housing, and the lever lower end has increased the distance of lever lower end bump housing at the inner secundly of housing flat, makes the spanner sender more obvious.A roller respectively is housed in the groove on the rightabout of slide block top and the bottom, keeps rolling friction between slide block and the housing, reduced the frictional resistance of slide block and housing.
The utility model compared with prior art, message is little when not only having overcome spanner work, feel is vibrated unconspicuous shortcoming, the spanner sender sound strengthens, and with the sensation that slides that significantly dallies, still can obviously discover the signal that spanner sends when making in the working environment that the operator is big at noise, vibration is big operation, and, also obviously improve and improved the stability of wrench torque value precision and moment values.
Concrete structure of the present utility model is by providing in the accompanying drawing:
Fig. 1 is the front view of the utility model structure.
Fig. 2 is the left view of the utility model structure.
For ease of understanding the utility model, be elaborated by the embodiment that provides in the accompanying drawing:
The utility model by 1, ratchet head; 2, lever pin; 3, lever; 4, housing; 5, pin; 6, contiguous block; 7, pin; 8, roller; 9, pin; 10, slide block; 11, roller; 12, pin; 13, spring washer; 14, spring; 15, groove sleeve pipe; 16, clamp ring; 17, composition such as handle
Design feature of the present utility model is as shown in Figure 1: lever (3) top and ratchet head (1) match, and lever (3) flexibly connects by lever pin (2) and housing (4).Housing (4) is shaped as flat circle down, and lever (3) lower end is at the inner secundly of the flat of housing (4), and another side and housing (4) have the gap that can supply lever (3) to do swing.Contiguous block (6) respectively flexibly connects with lever (3) and slide block (10) respectively by pin (5) and pin (7).Roller (8) and roller (11) respectively are contained in respectively in the opposite groove of the top and the bottom direction of slide block (10) by pin (9) and pin (12).The cylindrical of roller (8) and roller (11) contacts with the inwall of housing (4), and two rollers roll on the opposite inwall of housing (4) direction respectively during spanner work.Slide block (10) lower end contacts with spring washer (13), and spring washer (13) contacts with spring (14).The top of lever (3), contiguous block (6) and slide block (10) is contained in the flat inside of housing (4), and the bottom of slide block (10), spring washer (13) and spring (14) are contained in the circular interior of housing (4).Rotating spanner, when output torque arrived the indicating value moment values, original position is sent " clatter " to housing (4) bump sound news were departed from lever (3) lower end.Contiguous block this moment (6) is followed lever (3) on one side and is rotated, and does to move axially with respect to housing (4) Yi Bian oppress slide block (10), and its move mode is by roller (8) and roller (11) housing (4) to be done the rolling slippage.
When using the utility model, handle (17) is rotated to required moment values place (the horizontal groove on vertical groove on the groove sleeve pipe (15) and the housing (4) shows moment values), rotation lock collar then (16) can not relatively rotate both handle (17) and housing (4) locking.Hold handle (17) rotating spanner and promptly stop firmly to the sound news of sending " clatter " (this moment is with the sensation that slides of spanner idle running), each correlated parts of spanner sets back immediately automatically.
Claims (3)
1, a kind of bidirectional rolling formula torque spanner that is used to screw the threaded fastener that moment requires, its technical characterictic is that lever (3) and contiguous block (6) flexibly connect by pin (5), contiguous block (6) flexibly connects by pin (7) with slide block (10), slide block (10) lower end contacts with spring washer (13), and a roller (8) and roller (11) respectively are equipped with in the upper and lower of slide block (10).
2, by the described bidirectional rolling formula of claim 1 torque spanner, its technical characterictic is that the top of lever (3), contiguous block (6) and slide block (10) is contained in the flat inside of housing (4), lever (3) lower end is at the flat inwall place of housing (4) secundly, another side has the gap that can supply lever (3) to do swing, and the lower end of slide block (10) contacts with the circular interior of spring washer (13) at housing (4).
3, by the described bidirectional rolling formula of claim 1 torque spanner, its technical characterictic is that roller (8) and roller (11) respectively are contained in respectively in the opposite groove of the top and the bottom direction of slide block (10) by pin (9) and pin (12).
