Description

Technical Field

[0001] The utility model relates to the field of torque acquisition devices, and particularly to a torque acquisition device for a clutch fixed-torque screwdriver. Background Art

[0002] Screwdrivers are commonly used tools in assembly equipment. Most traditional screwdrivers are divided into two types. One type has a coaxial handle part and rotating part, and the other type has a perpendicular handle part and rotating part. And the torque acquisition device, namely the torque tester, is a precision instrument used for detecting, testing and calibrating various torques.

[0003] Chinese authorized publication number CN208380102U discloses a detector device for torque data detection, including a bottom plate and a torque detector body. An adjustment groove is formed on the upper surface of the bottom plate, and the torque detector body is rotatably connected to the inner wall of the adjustment groove. A threaded column is rotatably connected to the inner wall of the adjustment groove. A sliding block is threadedly connected to the surface of the threaded column. An adjustment rod is rotatably connected to the upper surface of the sliding block, and the other end of the adjustment rod is rotatably connected to the back of the torque detector body. When detecting the torque of an electric screwdriver, this detector device for torque data detection can first insert the electric screwdriver through the electric screwdriver insertion port and connect it to the detection end, and then rotate the second rotating disk to drive the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw enables the positioning plate to press and fix the electric screwdriver through two moving mounting blocks, avoiding the need for the detector to rely on hand strength to support the electric screwdriver throughout the detection process, which provides convenience for the detector.

[0004] However, this device has the following defects in use: Although this device can avoid the influence of the operator's hand interference on the measurement result, this device can only measure screwdrivers with a coaxial handle part and rotating part, and cannot measure screwdrivers with a perpendicular handle part and rotating part, which has limitations. In view of the above defects, we propose a torque acquisition device for a clutch fixed-torque screwdriver. Content of the Utility Model

Detailed implementation mode

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] Please refer to Figure 1-8 , the present invention provides a technical solution: a torque acquisition device for a clutch fixed-torque screwdriver, including: a torque acquisition device main body, a screwdriver limit structure, an adjustment structure, and a screwdriver guide structure.

[0035] Refer to Figure 1 , the torque acquisition device main body includes a torque acquisition head 1 and a data acquisition unit 2. The torque acquisition head 1 is a component that directly bears torque and usually measures torque using strain gauges or Hall sensors, etc. The data acquisition unit 2 is a component that processes measurement signals, converts the signals of strain gauges or Hall sensors into available electrical signals, and displays the measurement results. The torque acquisition head 1 and the data acquisition unit 2 are both prior arts, so they will not be elaborated here.

[0036] The screwdriver limit structure includes a support frame and a screwdriver clamping assembly arranged on the surface of the support frame.

[0037] The support frame includes a base plate 3, a telescopic cylinder 4 fixedly installed on the upper surface of the base plate 3, a telescopic rod 5 slidably installed on the inner wall of the telescopic cylinder 4, and a mounting plate 6 fixedly installed at the upper end of the telescopic rod 5. The support frame is used to support the screwdriver clamping assembly, and the base plate 3 is used to place the torque acquisition head 1.

[0038] Refer to Figure 3 , the screwdriver clamping assembly includes a mounting seat 7, a threaded rod 8 rotatably installed on the inner wall of the mounting seat 7, and two clamping plates 9 respectively threadedly connected to the surface of the threaded rod 8. The shape of the clamping plate 9 is set to be semi-circular. The surface of the threaded rod 8 is provided with two threads with opposite rotation directions, and the two clamping plates 9 are respectively in screw drive with the two threads. The right end of the threaded rod 8 extends to the outside of the mounting seat 7 and is provided with a handle 20. Rotating the handle 20 can drive the threaded rod 8 to rotate, and by using the screw drive between the threaded rod 8 and the clamping plate 9, the two clamping plates 9 can be driven to clamp the handle part of the screwdriver.

[0039] Refer to Figure 4-5, the adjustment structure includes a guide rod 10 fixedly installed on the back surface of the mounting base 7, a cross-shaped adjustment block 11 fixedly installed on the surface of the guide rod 10, a guide hole opened on the front surface of the mounting plate 6 for the guide rod 10 to pass through, and a cross-shaped limiting groove 12 opened on the inner wall of the guide hole and adapted to the cross-shaped adjustment block 11. The back surface of the guide rod 10 passes through the guide hole, and a baffle 13 is rotatably installed. The baffle 13 can prevent the guide rod 10 from detaching from the guide hole. The cross-shaped adjustment block 11 can limit the mounting base 7. And when the handle part of the screwdriver is clamped by the screwdriver clamping assembly, changing the angle at which the cross-shaped adjustment block 11 is inserted into the cross-shaped limiting groove 12 can change the angle of the mounting base 7, thereby changing the angle of the handle part of the screwdriver.

[0040] A compression spring 14 is sleeved on the surface of the guide hole. One end of the compression spring 14 is fixedly connected to the front surface of the baffle 13, and the other end of the compression spring 14 is fixedly connected to the back surface of the mounting plate 6. In the initial state, the compression spring 14 can drive the cross-shaped adjustment block 11 to insert into the cross-shaped limiting groove 12.

[0041] When detecting a screwdriver with its handle part and rotating part coaxial, the handle part of the screwdriver can be clamped by the screwdriver clamping assembly. At this time, the rotating part of the screwdriver can be inserted onto the torque acquisition head 1, and then the screwdriver is driven to rotate. The torque acquisition head 1 bears the torque, so that the torque of the screwdriver with its handle part and rotating part coaxial can be measured.

[0042] When detecting a screwdriver with its handle part and rotating part perpendicular, the handle part of the screwdriver is clamped by the screwdriver clamping assembly. After pulling the mounting base 7 to drive the cross-shaped adjustment block 11 to disengage from the cross-shaped limiting groove 12, the mounting base 7 is rotated by 90 degrees, and then the mounting base 7 is released. Thus, the compression spring 14 can be used to drive the cross-shaped adjustment block 11 to insert into the cross-shaped limiting groove 12, and further change the angle of the mounting base 7. At this time, the handle part of the screwdriver will be perpendicular to the torque acquisition head 1, and the rotating part of the screwdriver will be coaxial with the torque acquisition head 1, so that the screwdriver with its handle part and rotating part perpendicular can be measured, and the flexibility of the device can be improved.

[0043] Refer to Figure 2 and Figure 6 , the screwdriver guiding structure is arranged on the lower surface of the mounting plate 6 and is used for guiding the screwdriver. The screwdriver guiding structure includes a U-shaped frame 15 fixedly installed on the lower surface of the mounting plate 6, a sliding groove opened on the lower surface of the U-shaped frame 15, an L-shaped guiding plate 16 slidably installed on the inner wall of the sliding groove, a through hole opened on the upper surface of the L-shaped guiding plate 16, and a guiding ring 17 rotatably installed on the inner wall of the through hole.

[0044] A limiting component for limiting the L-shaped guide plate 16 is provided on the back surface of the U-shaped frame 15. The limiting component includes a strip-shaped groove 18 opened on the back surface of the U-shaped frame 15, a locking bolt 19 slidably mounted on the inner wall of the strip-shaped groove 18, and a threaded hole opened on the back surface of the L-shaped guide plate 16. Sliding the L-shaped guide plate 16 can change the position of the guide ring 17. At this time, the locking bolt 19 will slide along the inner wall of the strip-shaped groove 18. And by tightening the locking bolt 19, the L-shaped guide plate 16 can be fixed in the sliding groove by the frictional force between the locking bolt 19 and the U-shaped frame 15.

[0045] When measuring a screwdriver with a handle part perpendicular to the rotating part, the L-shaped guide plate 16 can be slid, and the guide ring 17 can be moved directly below the rotating part of the screwdriver. Then, the rotating part of the screwdriver is inserted into the guide ring 17, so that the rotating part can be quickly guided, avoiding the rotating part of the screwdriver being inclined to the torque acquisition head 1, and thus avoiding the need to repeatedly adjust the angle of the handle part of the screwdriver.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by those skilled in the art according to the technical solution and concept of the present invention should be covered within the protection scope of the present invention.
