Currently, existing testing equipment for spindle tensile gauges has limited functionality, necessitating the use of multiple devices, increasing costs, and hindering the application of fatigue testing, sealing checks, and oil leakage detection. Furthermore, existing equipment is prone to misalignment or shaking during tensile gauge testing. Therefore, a spindle tensile gauge testing machine needs to be designed to address these issues.

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. The shaft tension gauge is placed and supported using mounting components. The control unit consists of a PLC, a programmable controller, a servo drive circuit, and a hand pulse encoder. The servo drive uses torque mode, and the circuit controls the drive to move the drive component up and down. Different torques are output on the screen according to the specifications and models of different tension gauges. The drive component moves the shaft tension gauge through the top connector. The control box can electrically control the drive component, allowing the control box to detect different models of shaft tension gauges through the drive component.
[0013] 2. The first and second support plates are supported and installed by four first support rods. The mounting base is screwed to the second support plate. The four second support rods on the bottom inner side of the main body support and fix the third support rod by a fixing plate. The third support rod is fixed to the electric cylinder by the third support plate. The electric cylinder drives the tension sensor to pull the shaft tension gauge through the telescopic rod. The screen on the top of the control box outputs different torques according to the specifications of different shaft tension gauges, so that the electric cylinder can move up and down. When the set torque is reached, the operation will stop and the electric cylinder will lock. At this time, the tension sensor transmits the data to the display through the transmitter. At the same time, the pressure gauge of the main shaft tension gauge displays the data. The two values are equal, which means it is qualified.
[0014] 3. Push the locking handle to the top until it stops at the bottom plane of the mounting base. The groove at the bottom of the shaft tension gauge is flush with the ball. At this time, the shaft tension gauge can be inserted into the conical cavity or pulled out vertically. When the locking handle is pulled down to the lower positioning ring, it stops. At this time, the ball will move inward under the force of the inclined plane. At this time, the tension gauge cannot be pulled out vertically, thus achieving the locking state.
[0015] If pulled out again, the locking / releasing handle is pushed up to the bottom of the mounting base. When pushing and pulling out, the horizontal thrust is distributed to the ball bearings, causing the ball bearings to switch between locked and released states. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1
[0023] Please refer to Figure 1-4 As shown, this utility model provides a shaft tensile tester, including a tester housing body 1. A control box 2 is installed on the top of the body 1 and near one side. An mounting component for placing a shaft tensile tester 7 is installed on the top of the body 1 and on the other side of the control box 2. A drive component for pulling the shaft tensile tester 7 is installed at the bottom of the mounting component. A connecting component for mounting the shaft tensile tester 7 for testing is installed between the drive component and the mounting component.
[0024] Additionally, the shaft tension gauge 7 is placed and supported using mounting components. The control unit consists of a PLC, a programmable controller, a servo drive circuit, and a hand pulse encoder. The servo drive uses torque mode, and the circuit controls the drive to move the drive component up and down. Different torques are output on the screen according to the specifications and models of different tension gauges. The drive component moves the shaft tension gauge 7 through the top connector. The control box 2 is electrically connected to the drive component to control it, so that the control box 2 can detect different models of shaft tension gauges 7 through the drive component.
[0025] Specifically, the mounting components include a first support plate 3 mounted on the top of the main body 1 and located on one side of the control box 2. First support rods 4 are mounted on the top four sides of the first support plate 3. A second support plate 5 is mounted on the top of the first support rods 4. A mounting base 6 is mounted on the inner side of the second support plate 5. The first support rods 4 are fixed to the second support plate 5 with nuts. The inner side of the mounting base 6 is used to place a shaft tension gauge 7. The driving components include four second support rods 8 arranged circumferentially on the top inner side of the main body 1. A fixing plate 9 is mounted on the top of the second support rods 8. Third support rods 10 are mounted on the bottom four sides of the fixing plate 9. A third support plate 11 is mounted on the bottom of the third support rods 10. An electric cylinder 12 is mounted on one side of the third support plate 11. A telescopic rod 13 is mounted on the top of the electric cylinder 12. A tension sensor 14 is mounted on the top of the telescopic rod 13. A support ring 20 is fixedly connected to the outer side of the first support rod 4 near its top. The tension sensor 14 is mounted via an adapter screw. The third support rods 10 and the third support plate 11 are screwed together with nuts.
[0026] The first support plate 3 and the second support plate 5 are supported and installed by four first support rods 4. The first support rods 4 support the second support plate 5 upward through the support ring 20. The mounting base 6 is screwed to the second support plate 5. The four second support rods 8 on the bottom inner side of the main body 1 support and fix the third support rod 10 through the fixing plate 9. The third support rod 10 fixes the electric cylinder 12 through the third support plate 11. The electric cylinder 12 drives the tension sensor 14 to pull the shaft tension gauge 7 through the telescopic rod 13. The screen on the top of the control box 2 outputs different torques according to the specifications of different shaft tension gauges 7, so that the electric cylinder can move up and down. When the set torque is reached, the operation will stop and the electric cylinder will lock. At this time, the tension sensor 14 transmits the data to the display through the transmitter. At the same time, the pressure gauge of the main shaft tension gauge 7 displays the data. The two values are equal, which means that it is qualified.
[0027] More specifically, the connector includes a locking handle 15 installed inside the mounting base 6. A groove 16 is provided on the inner side of the locking handle 15 near one end. A tension rod 17 is installed inside the locking handle 15. A plurality of circumferentially arranged balls 18 are embedded in the inner side of the tension rod 17. A positioning ring 19 is fitted on the outer side of the tension rod 17 for fixed connection. The tension sensor 14 is connected to the tension rod 17 via an adapter screw. A plurality of circumferentially arranged limiting grooves 21 are provided on the outer wall of the locking handle 15. A plurality of circumferentially arranged limiting blocks 22 are installed inside the mounting base 6. The limiting blocks 22 are slidably connected to the limiting grooves 21.
[0028] Furthermore, multiple limiting blocks 22 on the outer side of the mounting base 6 can slide within the limiting groove 21 of the locking handle 15. The limiting blocks 22 limit and guide the locking handle 15. When the locking handle 15 is pushed to the top and stopped at the lower plane of the mounting base 6, the groove at the bottom of the shaft tension gauge 7 is flush with the ball 18. At this time, the shaft tension gauge 7 can be placed into the conical cavity or pulled out vertically. When the locking handle 15 is pulled down to the lower positioning ring 19, it stops. At this time, the ball 18 will move inward under the force of the inclined plane. At this time, the tension gauge cannot be pulled out vertically, thus achieving the locking state.
[0029] If pulled out again, the locking / releasing handle 15 is pushed up to stop under the mounting base 6. When it is pushed out, the horizontal thrust can be distributed to the ball bearing 18, causing the ball bearing 18 to switch between the locked and released states.
[0030] Working principle: Push the locking handle 15 to the top until it stops at the bottom plane of the mounting base 6. The groove at the bottom of the shaft tension gauge 7 is flush with the ball bearing 18. At this time, the shaft tension gauge 7 can be placed into the conical cavity of the mounting base 6. When the locking handle 15 is pulled down to the lower positioning ring 19, it stops. At this time, the ball bearing 18 will move inward under the force of the inclined plane to install and fix the shaft tension gauge 7. The electric cylinder 12 drives the tension sensor 14 to pull the shaft tension gauge 7 through the telescopic rod 13. The screen on the top of the control box 2 outputs different torques according to the different specifications of the shaft tension gauge 7, so that the electric cylinder can move up and down. When the set torque is reached, it will stop and the electric cylinder 12 will lock. At this time, the tension sensor 14 transmits the data to the display through the transmitter. At the same time, the pressure gauge of the main shaft tension gauge 7 displays the data. The two values are equal, which means it is qualified.
