Abstract
The utility model discloses a sleeve with a torque sensing function, which relates to the technical field of sleeves. The sleeve comprises a lower cube and an upper cube, wherein the top of the lower cube is provided with a cylindrical hole; the bottom of the lower cube is provided with a sleeve hole; the bottom of the upper cube is provided with a round platform matched with the cylindrical hole; a wrench extends from the top of the upper cube; a stress hole is formed at a position at which the round platform of the upper cube is matched with the cylindrical hole of the lower cube; a pin shaft is inserted into the stress hole; and a torque sensor is arranged on the wrench. The sleeve with the torque sensing function is provided with a torque protection device and the torque sensor, and is safe to use.
Description
Technical field
The utility model relates to the sleeve technology field.
Background technology
When some big screws of rotation, often to use sleeve, sleeve mainly comprises sleeve body and handle, during use, sleeve body is enclosed within the nut outside and is rotated use.Its weak point is that existing sleeve does not have torque limiter, when using the sleeve rotary screw, if firmly excessive, may cause the damage of screw thread and nut.Existing sleeve generally is not provided with torque sensor, can not monitor the moment that sleeve is subjected in real time.
Summary of the invention
Do not have torque limiter in order to overcome existing sleeve, do not have the deficiency of torque sensor, the utility model provides a kind of sleeve with moment sensing function, and this sleeve with moment sensing function has torque limiter, and torque sensor is arranged, and is safe in utilization.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of sleeve with moment sensing function, comprise the below body, the top of below body is provided with cylindrical hole, the bottom of below body is provided with trepanning, also comprises the top body, and the bottom of top body is provided with the round platform that is complementary with cylindrical hole, the top of top body is extended with spanner, the position that top body round platform and below body cylindrical hole are complementary is provided with stress hole, is inserted with bearing pin in the stress hole, and torque sensor is installed on the spanner.
Because this sleeve with moment sensing function comprises the below body, the top of below body is provided with cylindrical hole, the bottom of below body is provided with trepanning, also comprise the top body, the bottom of top body is provided with the round platform that is complementary with cylindrical hole, and the top of top body is extended with spanner, and the position that top body round platform and below body cylindrical hole are complementary is provided with stress hole, be inserted with bearing pin in the stress hole, torque sensor is installed on the spanner.Therefore this sleeve with moment sensing function has torque limiter, and torque sensor is arranged, and is safe in utilization.
Description of drawings
Fig. 1 is the structure chart that the utlity model has the sleeve of moment sensing function.
The specific embodiment
As shown in Figure 1, a kind of sleeve with moment sensing function, comprise below body 1, the top of below body 1 is provided with cylindrical hole 6, and the bottom of below body 1 is provided with trepanning 8, also comprise top body 2, the bottom of top body 2 is provided with the round platform 5 that is complementary with cylindrical hole, and the top of top body 2 is extended with spanner 4, and the position that top body round platform and below body cylindrical hole are complementary is provided with stress hole 3, be inserted with bearing pin 7 in the stress hole 3, on the spanner 4 torque sensor be installed.Bearing pin 7 couples together below body 1 and top body 2, and bearing pin 7 has moderate and stable shear strength, and when using this sleeve rotary nut, if firmly excessive, bearing pin 7 can rupture by nature, plays the effect of protection screw and nut.Torque sensor can be monitored the moment that sleeve is subjected in real time, and is easy to use.Therefore this sleeve with moment sensing function has torque limiter, and torque sensor is arranged, and is safe in utilization.
