Description

Technical Field

[0001] The utility model relates to the technical field of torque wrenches, in particular to a calibration tool for digital torque wrenches. Background Art

[0002] A torque wrench, also known as a torque wrench or adjustable torque wrench, is a type of wrench. When the tightness of screws and bolts is critical, a torque wrench allows the operator to apply a specific torque value. In order to ensure the accuracy and reliability of the torque value of the torque wrench, it is necessary to regularly use a torque wrench calibration device to test and calibrate the torque of the wrench.

[0003] The existing calibration equipment is usually limited to calibrating a single digital torque wrench, and then the next digital wrench needs to be reinstalled before calibration. This process results in low calibration efficiency of digital torque wrenches and easily causes delays in large-scale products. Utility Model Content

[0015] The present invention will be described in further detail below with reference to the accompanying drawings.

[0016] Embodiment 1: A calibration tool for a digital torque wrench includes a calibration platform 1 , a transverse slot 2 is provided on the calibration platform 1 , a conveyor belt 3 is provided on the transverse slot 2 , and the conveyor belt 3 is used to successively convey the digital torque wrenches into the transverse slot 2 .

[0017] A lifting platform 4 is provided on the inner wall above the transverse groove 2 on the calibration platform 1 . The lifting of the lifting platform 4 is achieved by a lifting motor 13 or an electric push rod.

[0018] A set screw is installed vertically downward at the front end of the lift platform 4, and a single thrust plate 6 is installed at the rear end of the lift platform 4. A fixed nut 5 is fixed to the lift platform 4. When the lift platform 4 descends, it can be inserted into a specific slot at the front end of the digital torque wrench, allowing the fixed nut 5 to mate with the front end of the wrench. The thrust plate 6 is driven by a thrust motor 13 installed on the side of the lift platform 4, pushing the rear end of the digital torque wrench out, forming an angle with the fixed front end wrench position, thereby triggering the digital readout on the digital torque wrench.

[0019] The lower surface of the lifting platform 4 is provided with two transverse slide rails 7, each of which is provided with a sliding seat 8 on either side. The sliding seat 8 is provided with a transverse slot 14, and a clamping block 15 is inserted into the transverse slot 14. A rotatable diamond block 9 is provided in the middle of the lower surface of the lifting platform 4. Articulated rods 10 are provided between the ends of the diamond block 9 and the sliding seat 8. The middle of the lifting platform 4 is provided with a drive device that drives the diamond block 9 to rotate back and forth.

[0020] The driving device is a cylinder 11 installed at the bottom of one of the sliding seats 8. The front end of the cylinder 11 is mounted on the rotating shaft of the diamond-shaped block 9. When the cylinder 11 is activated, it can drive the sliding seats 8 on both sides to reciprocate, so that the clamping blocks 15 can clamp the digital torque wrench. In this arrangement, the purpose of using a transverse slot 14 is to facilitate the replacement of the clamping blocks 15, thereby accommodating digital torque wrenches of different sizes.

[0021] Openings are provided on the lifting platform 4 and the calibration platform 1 for viewing the readings. The thrust applied by the thrust plate 6 is set to a certain value. If the reading on the digital torque wrench fails, it means that the digital torque wrench fails. Preferably, a high-definition camera can be set for recognition, and the recognized data is sent to a predetermined value for comparison. If the recognized value exceeds the predetermined value, an alarm is issued, thereby ensuring that the process can be carried out automatically and reducing labor costs.

[0022] It should be noted that the purpose of the clamping block 15 on the sliding seat 8 is to ensure the positioning of the digital torque wrench to facilitate the mating of the digital torque wrench with the fixing nut 5. After the digital torque wrench and the fixing nut 5 are fully assembled, the clamping block 15 on the sliding seat 8 can be released to prevent it from affecting the subsequent pushing of the thrust plate 6.

[0023] Example 2: This example is similar to Example 1, except that the drive device is provided in an insertion opening 12 on the lower surface of the lifting platform 4. A motor 13 is provided in the insertion opening 12, and the rotating shaft of the motor 13 is connected to the diamond block 9. The motor 13 rotates forward and reverse at regular intervals to achieve the clamping of the digital torque wrench.

[0024] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
