Description

Technical Field

[0001] This utility model relates to the technical field of torque detection devices, and more specifically, to a hydraulic wrench torque detector. Background Technology

[0002] A hydraulic wrench is a device that uses the pressure of hydraulic oil as a power source to tighten bolts, nuts, and other fasteners. After the hydraulic wrench is manufactured, its output torque needs to be tested. To address this, Chinese Patent Publication No. CN219757586U discloses a hydraulic wrench torque tester. This tester includes a rotating seat rotatably connected to the top of the tester body. A square head with a square hole is movably engaged on the rotating seat. The square head has a circular cross-section. A rotating plate is fixed to the outside of the rotating seat. An adjusting inner plate is mounted on the rotating plate via an adjusting fixing component. A movable sleeve is movably fitted on the outside of the adjusting inner plate. Two symmetrically arranged rotating guide posts are mounted on the top of the movable sleeve via a moving component. A transmission component connects the rotating plate and the tester body. While the aforementioned hydraulic wrench torque tester can detect the torque of a hydraulic wrench, it suffers from drawbacks such as large size and complex structure. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a hydraulic wrench torque tester, which has the advantages of small size and simpler structure, as well as being easy to use.

[0004] This utility model provides a hydraulic wrench torque detector, including a housing, a cover plate, a torque sensor, an adapter, a display screen, and a stop block. The cover plate is fixed to the upper end of the housing. The torque sensor is located inside the housing, with its lower end fixed to the inner bottom of the housing. The adapter is coaxially fixed to the upper end of the torque sensor, with its upper end movably passing through the cover plate and extending outside the cover plate. A square recess is provided in the middle of the upper end of the adapter for mating with the output end of the hydraulic wrench. The display screen is fixed to the front side of the housing. Both the torque sensor and the display screen are electrically connected to a controller located inside the housing. The stop block is located above the cover plate and on one side of the adapter. The stop block is used to abut against the handle of the hydraulic wrench and is connected to the housing.

[0005] By adopting the above-described structure, this invention allows for simple operation: the output end of the hydraulic wrench is inserted into the square recess, and the handle of the hydraulic wrench abuts against the stop block. When the hydraulic wrench outputs torque, the handle is limited by the stop block, thus the torque acts on the adapter and torque sensor. The torque sensor transmits the torque data to the controller, which converts the torque data into a torque value and displays it on the screen. Through this process, the torque of the hydraulic wrench can be detected. Compared with existing hydraulic wrench torque detectors, this invention has the advantages of small size and simpler structure, as well as ease of use.

[0006] In one possible implementation, the hydraulic wrench torque detector further includes a support sleeve and a connector; the support sleeve is disposed inside the housing, with its lower end fixed to the inner bottom of the housing, and the lower end of the connector coaxially fixed to the upper end of the support sleeve, the upper end of the connector extending out of the cover plate after passing through it, and a stop block connected to the upper end of the connector; with this structure, under the action of the support sleeve and the connector, the stop block can be reliably connected to the housing via the connector and the support sleeve.

[0007] In one possible implementation, the outer wall of the upper end of the connector is circumferentially provided with splines, the middle of the stop block is vertically provided with an insertion hole, and the inner wall of the insertion hole is circumferentially provided with a spline groove. The upper end of the connector is inserted into the insertion hole so that the splines and spline grooves engage and limit the circumferential movement of the stop block and the connector. With this structure, the stop block can be inserted into the connector by engaging, which has the advantages of convenient assembly of the stop block and the connector, i.e., convenient connection between the stop block and the housing. Moreover, when performing torque tests on different hydraulic wrenches, stop blocks of different shapes or sizes can be used to meet the abutment requirements of the stop block and the hydraulic wrench handle. In addition, when each protrusion in the spline teeth engages with different grooves in the spline groove, the horizontal angle of the stop block relative to the housing can be adjusted. That is, after the output end of the hydraulic wrench engages with the square recess, the horizontal angle of the stop block relative to the housing can be adjusted so that the stop block reliably abuts against the hydraulic wrench handle.

[0008] In one possible implementation, the hydraulic wrench torque tester also includes a connecting plate and a handle; the connecting plate is fixed to the middle of the upper end of the stop block, and the lower end of the handle is provided with a screw part, which is threadedly fastened to a threaded hole vertically provided in the middle of the connecting plate; with this structure, when it is necessary to adjust the horizontal angle of the stop block relative to the housing or to replace the stop block, the stop block can be easily pulled up by the handle to disengage the stop block from the connecting piece.

[0009] In one possible implementation, handles are fixed on both the left and right sides of the upper end of the housing; by providing handles, the hydraulic wrench torque tester can be gripped when it needs to be moved, thereby facilitating the movement of the hydraulic wrench torque tester.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0017] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] See Figure 1-4As shown in the figure, this application discloses a hydraulic wrench torque detector, including a housing 1, a cover plate 2, a torque sensor 3, an adapter 4, a display screen 5, and a stop block 6. The cover plate 2 is fixed to the upper end of the housing 1. The torque sensor 3 is disposed inside the housing 1, with its lower end fixed to the inner bottom of the housing 1. The adapter 4 is coaxially fixed to the upper end of the torque sensor 3. The upper end of the adapter 4 extends through the cover plate 2 and out of the cover plate 2. A square recess 41 is provided in the middle of the upper end of the adapter 4 for engaging with the output end of the hydraulic wrench. The display screen 5 is fixed to the front side of the housing 1. Both the torque sensor 3 and the display screen 5 are electrically connected to a controller located inside the housing 1. The stop block 6 is located above the cover plate 2 and on one side of the adapter 4. The stop block 6 is used to abut against the handle of the hydraulic wrench and is connected to the housing 1.

[0019] When using this invention, simply insert the output end of the hydraulic wrench into the square recess, and then make the handle of the hydraulic wrench abut against the stop block. When the hydraulic wrench outputs torque, since the handle of the hydraulic wrench is limited by the stop block, the torque of the hydraulic wrench can act on the adapter and the torque sensor. At this time, the torque sensor can transmit the torque data to the controller, and the controller can convert the torque data obtained by the torque sensor into a torque value and display it on the display screen. Through the above process, the torque of the hydraulic wrench can be detected.

[0020] The hydraulic wrench torque tester also includes a support sleeve 7 and a connector 8. The support sleeve 7 is located inside the housing 1, with its lower end fixed to the inner bottom of the housing 1. The lower end of the connector 8 is coaxially fixed to the upper end of the support sleeve 7, and the upper end of the connector 8 extends through the cover plate 2 and out of the cover plate 2. The stop block 6 is connected to the upper end of the connector 8. With this structure, under the action of the support sleeve and the connector, the stop block can be reliably connected to the housing via the connector and the support sleeve.

[0021] The upper outer wall of the connector 8 is circumferentially provided with spline teeth 81, and the middle of the stop block 6 is vertically provided with a socket 61. The inner wall of the socket 61 is circumferentially provided with a spline groove 62. The upper end of the connector 8 is inserted into the socket 61 so that the spline teeth 81 and the spline groove 62 are engaged and inserted to limit the circumferential movement of the stop block 6 and the connector 8. With this structure, the stop block can be inserted into the connector by engaging and inserting, which has the advantages of convenient assembly of the stop block and the connector, that is, convenient connection between the stop block and the housing. When performing torque tests on different hydraulic wrenches, stop blocks of different shapes or sizes can be used to meet the abutment requirements of the stop block and the hydraulic wrench handle. In addition, when each protrusion in the spline teeth engages with different grooves in the spline groove, the horizontal angle of the stop block relative to the housing can be adjusted. That is, after the output end of the hydraulic wrench is engaged with the square countersunk groove, the horizontal angle of the stop block relative to the housing can be adjusted so that the stop block reliably abuts against the hydraulic wrench handle.

[0022] The hydraulic wrench torque tester also includes a connecting plate 63 and a handle 64; the connecting plate 63 is fixed to the middle of the upper end of the stop block 6, and the lower end of the handle 64 is provided with a screw part 641, which is threadedly fastened to the threaded hole 631 vertically provided in the middle of the connecting plate 63; with this structure, when it is necessary to adjust the horizontal angle of the stop block relative to the housing or to replace the stop block, the stop block can be easily pulled up by the handle to disengage the stop block from the connecting part.

[0023] Handles 9 are fixed on both the left and right sides of the upper end of the housing 1; by setting the handles, when it is necessary to move the hydraulic wrench torque tester, the handles can be gripped, which makes it convenient to move the hydraulic wrench torque tester.

[0024] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
