Description

Technical Field

[0001] The utility model relates to the technical field of tapping torque testing equipment, in particular to a tapping torque testing machine. Background Art

[0002] When using conventional tapping torque testing equipment, it is necessary to control the height of the tap through an operating arm and conduct tests. In addition, for testing nut samples of different specifications, it is necessary to adjust the position of the oil box mechanism below and align the nut sample of the corresponding specification with the central axis of the transmission screw. Once misalignment occurs, the above device cannot be used normally. In other words, the staff is required to accurately and quickly switch the position of the oil box mechanism corresponding to the nut sample, which is cumbersome to operate. In addition, the way the oil box mechanism arranges nut samples of multiple specifications does not make it easy to set up a sensor for detecting torque. Utility Model Content

[0003] In order to solve the problem that the above-mentioned tapping torque test equipment needs workers to control the lifting and lowering and it is not easy to set a sensor on the oil box mechanism, the utility model provides a tapping torque tester.

[0004] The technical solution of this utility model is as follows:

[0005] A tapping torque tester comprises a cabinet, an oil box mechanism and a test mechanism arranged opposite to the oil box mechanism are arranged on the cabinet, the test mechanism is fixed to the upper surface of the cabinet through a control cabinet arranged on one side, and a driving mechanism is arranged in the control cabinet;

[0006] The test mechanism is provided with a driven wheel connected to the driving mechanism, a transmission shaft connected to the driven wheel, a main shaft connected to the transmission shaft through an electromagnetic clutch, a main shaft seat penetrated by the main shaft, a transmission screw connected to the main shaft, and a tap detachably provided at the lower end of the transmission screw.

[0007] The oil box mechanism comprises a rotatable circular worktable, the circular worktable is provided with a nut sample corresponding to the tap, and the circular worktable is provided with a sensor capable of detecting torque.

[0008] Different from the existing devices, the lifting and lowering of the transmission screw is automatically controlled and the lifting range is limited. After that, the setting method of the above-mentioned oil box mechanism can be adapted to the application by replacing the nut sample, and the above-mentioned method is convenient for setting the sensor.

[0009] The structure of the cabinet is that the cabinet includes a chassis and a storage table arranged on one side of the chassis, the upper surface of the chassis is a horizontal surface, and an oil box mechanism is arranged on it.

[0010] The oil box mechanism and the test mechanism are arranged in such a manner that the test mechanism is arranged above the oil box mechanism, and the central axis of the test mechanism is arranged vertically and is located on the same straight line as the central axis of the oil box mechanism.

[0011] The method of realizing automatic limit of the lifting of the transmission screw is that an adjustment plate is vertically arranged below the spindle seat, and a displacement plate is connected to the spindle sleeve, and the displacement plate can move up and down with the rotation of the spindle. The above process is automated, and the staff does not need to adjust the height of the transmission screw.

[0012] As a preferred solution, the displacement plate and the adjustment plate are arranged opposite to each other, and the moving range in the vertical direction is set by the adjustment plate.

[0013] The specific structure of the above-mentioned adjustment plate is that the adjustment plate is provided with a vertical waist-shaped hole, and sensors are provided at both ends of the waist-shaped hole, and the displacement plate is provided with a through column in the horizontal direction that penetrates the waist-shaped hole and can trigger the sensor. The waist-shaped hole limits the height of the displacement plate and controls it to prevent it from deviating from the preset range.

[0014] The method of setting the nut sample is that the circular workbench of the oil box mechanism is provided with a plug, and the nut sample is detachably provided on the plug and can rotate synchronously with the plug.

[0015] The above-mentioned tap is detachably arranged in such a manner that the tap is disassembled in a vertical direction relative to the transmission screw and the tap can rotate synchronously with the transmission screw. The tap can be disassembled and replaced without affecting the synchronous rotation.

[0016] As a preferred solution, the side panels of the control cabinet are ventilation panels.

[0017] In order to improve applicability, the tap is provided with multiple specifications.

[0018] The beneficial effects of the utility model are as follows: the utility model is a tapping torque testing machine, which is different from the existing equipment. The lifting and lowering of the transmission screw can be automatically controlled through the cooperation of the adjustment plate and the displacement plate, thereby being more automated. In the above structure, the forward and reverse rotation and relative rotation of the transmission shaft and the main shaft are controlled by the electromagnetic clutch, which is very convenient. Finally, by separately setting the oil box mechanism of the nut sample, it is convenient to set the sensor and to detect the torque data. In the above structure, considering the applicability, the tap and the nut sample can be replaced and matched at the same time, thereby facilitating the detection. Since the oil box mechanism cannot be positioned, it is only necessary to install the nut test in a fixed position to achieve alignment without the need for additional adjustment.

DETAILED DESCRIPTION

[0027] like Figure 1 , 4 The tapping torque testing machine shown in FIG. 1 comprises a cabinet 1 and a Figure 1 As shown, the structure of the cabinet 1 is that the cabinet 1 includes a chassis 11 and a storage table 12 arranged on one side of the chassis 11. The upper surface of the chassis 11 is a horizontal plane, and an oil box mechanism 4 is arranged, and the storage table 12 is located on one side, and a computer or other recording device can be arranged on one side for statistical data. The arrangement on one side can improve the overall stability of the cabinet 1.

[0028] The storage table 12 will not be described in detail. As for the main structure of the device, Figure 1 As shown, an oil box mechanism 4 and a test mechanism 3 arranged opposite to the oil box mechanism 4 are arranged on the upper surface of the chassis 11 of the cabinet 1, wherein taps of different specifications are arranged at one end of the test mechanism 3 close to the oil box mechanism 4, and a nut sample 44 is arranged at one end of the oil box mechanism 4 close to the test mechanism 3 and is arranged corresponding to the tap.

[0029] like Figure 2As shown, the test mechanism 3 is fixed on the upper surface of the cabinet 1 through a control cabinet 2 arranged on one side, and a driving mechanism is arranged in the control cabinet 2; and the test mechanism 3 is provided with a driven wheel 31 connected to the driving mechanism and a transmission shaft 32 connected to the driven wheel 31 in sequence from top to bottom. When the driving mechanism is turned on, the transmission shaft 32 can be driven to rotate synchronously, and then a main shaft 34 connected to the transmission shaft 32 through an electromagnetic clutch 33 is also provided. It should be noted that the device needs to perform forward and reverse rotation, so an electromagnetic clutch 33 is provided, which can freely control the relative relationship between the above-mentioned transmission shaft 32 and the main shaft 34, so that it can achieve relative rotation, synchronous rotation in the same direction, etc., and then it also includes a main shaft seat 35 penetrated by the main shaft 34, and the main shaft seat 35 is fixed to the control cabinet 2 to ensure that the central axis of the main shaft 34 is always in the same straight line. Finally, there is a transmission screw 38 connected to the main shaft 34 and a tap detachably provided at the lower end of the transmission screw 38.

[0030] like Figure 2 As shown, the detachable setting mode of the above-mentioned tap is that the disassembly direction of the tap relative to the transmission screw is in the vertical direction, and the tap can rotate synchronously with the transmission screw 38. The specifications can be disassembled and replaced without affecting the synchronous rotation. That is, the lower end of the transmission screw 38 is a hollow structure, and the upper end of the tap can be inserted into the above-mentioned hollow, thereby achieving fixation, and the plug-in structure cannot be circular, so that synchronous rotation can be ensured. Through the above method, the detachable and synchronous rotation of the tap can be achieved. At the same time, in order to improve the applicability of the equipment, the tap is set with multiple specifications.

[0031] Afterwards, in order to replace the staff to complete the up and down adjustment of the transmission screw rod 38, as shown in FIG. Figure 2 As shown, the way to realize the automatic limit of the lifting of the transmission screw 38 is that an adjustment plate 36 is vertically arranged below the spindle seat 35, and a displacement plate 37 is sleeved on the spindle 34, and the displacement plate 37 can move up and down with the rotation of the spindle 34. The above process is automated, and the staff does not need to adjust the height of the transmission screw. In the above structure, the displacement plate 37 is arranged opposite to the adjustment plate 36, and the moving range in the vertical direction is set by the adjustment plate 36, and the specific limiting method is as shown in the following structure.

[0032] As a preferred embodiment, the specific structure of the adjustment plate 36 is that the adjustment plate 36 is provided with a vertical waist-shaped hole, and sensors 41 are provided at both ends of the waist-shaped hole, and the displacement plate 37 is provided with a through column in the horizontal direction to penetrate the waist-shaped hole and can trigger the sensor 41. The waist-shaped hole limits the height of the displacement plate 37 and controls it to prevent it from deviating from the preset range. When in use, after the forward or reverse rotation triggers the sensor 41 at the corresponding position, the state is switched from forward rotation to reverse rotation or from reverse rotation to forward rotation.

[0033] Finally, if Figure 4 As shown, the oil box mechanism 4 includes a rotatable circular worktable 42, the circular worktable 42 is provided with a nut sample 44 corresponding to the tap, and the circular worktable 42 is provided with a sensor 41 capable of detecting torque. The position of the oil box mechanism 4 is fixed and cannot be moved, and the circular worktable 42 can only rotate along the central axis and cannot be moved. After the nut sample 44 is set, the test can be directly carried out without other adjustment operations.

[0034] In the above structure, the oil box mechanism 4 and the test mechanism 3 are arranged in such a way that the test mechanism 3 is arranged above the oil box mechanism 4, and the central axis of the test mechanism 3 is arranged vertically and is located on the same straight line as the central axis of the oil box mechanism 4. This ensures that the test mechanism 3 can be used normally and is convenient for testing operations.

[0035] like Figure 4 As shown, in the above structure, the nut sample 44 is provided in such a way that the circular worktable 42 of the oil box mechanism 4 is provided with a plug 43, and the nut sample 44 is detachably provided on the plug 43 and can rotate synchronously with the plug 43. The connection mode is plug-in, and the direction is vertical, that is, it can rotate synchronously and can also achieve the purpose of detachability. Through the above method, the tap and the nut sample 44 can be freely replaced, and synchronization and relative adaptability can be ensured.

[0036] To this end, the above-mentioned structure can be used to achieve that, unlike the existing device, the lifting and lowering of the transmission screw 38 is automatically controlled and the lifting and lowering range is limited. Afterwards, the setting method of the above-mentioned oil box mechanism 4 can be adapted to the application by replacing the nut sample 44, and the above-mentioned method is convenient for setting the sensor 41. The sensor 41 of the above-mentioned oil box mechanism 4 is used to monitor the torque, which is different from the sensor 41 set on the adjustment plate 36.

[0037] In addition to the above structure, in order to facilitate the long-term use of the driving mechanism, the side plate of the control cabinet 2 is a ventilation plate 21.
