[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand: the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 9 As shown, the present invention provides a technical solution: a ball head push-pull torque testing device, comprising a test bench 1, a mounting base 2 is fixedly connected to the top of the test bench 1, a threaded inner hole 3 is opened on the inner wall of the mounting base 2, a ball head assembly is arranged on the top of the mounting base 2, the ball head assembly comprises a ball head, a ball head connector and a threaded rod, the ball head connector is fixedly connected to the bottom of the ball head, the threaded rod is fixedly connected to the bottom of the ball head connector, the threaded inner hole 3 and the threaded rod are threadedly connected and adapted to each other, the ball head and the ball head connector are connected to the top of the mounting base 2 through the mutual cooperation of the threaded rod and the threaded inner hole 3, a torque assembly and a push-pull assembly for testing torque and push-pull force are respectively arranged on the outside of the ball head, and a marking assembly for marking the ball head is symmetrically arranged on the top of the test bench 1, and the two groups of marking assemblies mark the torque and push-pull test results respectively.

[0032] During operation: since the ball head with poor performance will be deformed after being subjected to push-pull force or torque, its internal structure or material performance has been damaged. The deformed ball head is difficult to judge by appearance, which may cause safety hazards in subsequent use of the ball head. The ball head and the ball head connector are fixed on the top of the test bench 1 through the cooperation of the threaded rod and the threaded inner hole 3, and then the ball head is subjected to torque and thrust at the same time through the torque component and the push-pull component, so as to carry out the test. The torque component applies a certain torque to the ball head, and the push-pull component applies thrust to the ball head. The ball head with poor performance will have different deformation states when subjected to the two forces, and the different deformation states will cause the two sets of marking components to perform different marking work. The marking results can directly judge whether the ball head with poor performance is subjected to a certain According to the test results of torque and thrust, a ball head with better performance will not be deformed when subjected to torque and thrust, and thus the marking component will not mark a ball head with normal performance. Through the above embodiment, when a ball head with poor performance is subjected to torque and thrust tests at the same time, different marking situations may appear according to different performance conditions, so as to judge the performance of the ball head. When a ball head with normal performance is subjected to torque and thrust tests at the same time, it will not be deformed and will not be marked by the marking component, thereby avoiding the deformed ball head being difficult to judge by appearance, which may cause safety hazards in subsequent use of the ball head. Through the form of marking, the performance of the ball head can be judged more intuitively and accurately, and when the torque component and the push-pull component are tested, there is no need to find the ball head to perform the ball head torque test.

[0033] like Figures 2 to 4 As shown, the torsion assembly includes two transverse plates 4, which are symmetrical. Push rods 6 are inserted into the inner walls of the two transverse plates 4, one end of the two push rods 6 is fixedly connected to a clamping pad 5, and the other end of the two push rods 6 is fixedly connected to a limiting sleeve 12, the outer walls of the two transverse plates 4 are fixedly connected to a connecting piece 7, one side of the two connecting pieces 7 is fixedly connected to a conducting electromagnet 8, and the two conducting electromagnets 8 are in a parallel relationship and the surfaces close to each other have opposite magnetic poles.

[0034] During operation: current is passed through the two electromagnets 8. Since the two electromagnets 8 are in parallel and the surfaces close to each other have opposite magnetic poles, the two electromagnets 8 will meet and connect together. At this time, the electromagnets 8 will make the two clamping pads 5 fit tightly against the outer wall of the ball head through the connecting piece 7, thereby tightly fitting against the outer wall of the ball head to achieve a clamping effect on the ball head. After the clamping effect is formed, a rotational force is applied to the clamping pads 5 and acts on the ball head, thereby achieving an effect of applying torque to the ball head.

[0035] like Figure 4As shown, a return spring 11 is disposed outside the two push rods 6 , one end of the return spring 11 is fixedly connected to one end of the limit sleeve 12 , and the other end of the return spring 11 is fixedly connected to one side of the cross plate 4 .

[0036] During operation: after the torque test of the ball head is completed through the reset spring 11, the current passed into the electromagnet 8 is turned off, so that the two electromagnets 8 have no magnetic properties, and the clamping pad 5 can be restored to its original position through the reset spring 11, and the electromagnet 8 can also be reset during the resetting process of the clamping pad 5, which is convenient for removing the ball head and preparing for the torque test of the next ball head.

[0037] like Figure 4 As shown, the torque assembly also includes a gear 10, an inner slide 9 is fixedly connected between the tops of the two horizontal plates 4, the gear 10 is fixedly installed on the top of the inner slide 9, two external connecting rods passing through the electromagnet 8 are respectively slidably connected to the inner wall of the inner slide 9, an inner slider 13 is fixedly connected to the bottom of the two horizontal plates 4, a slide groove 14 is provided on the inner wall of the top surface of the test bench 1, the inner slider 13 is slidably connected to the slide groove 14, and a power assembly is arranged on one side of the gear 10, which applies a certain power of rotational force to the gear 10.

[0038] When working: start the power assembly, the power assembly will apply a certain power torque to gear 10, and the torque exerted on gear 10 will act on the clamping pad 5 through the inner slide 9 and the cross plate 4. The torque exerted on the clamping pad 5 will form a torque on the ball head. When the torque performance of the ball head is poor, the torque of the clamping pad 5 on the ball head will cause the ball head to deform, and cause the cross plate 4 to rotate on the test bench 1 through the inner slide 13 and the slide groove 14, so gear 10 will also rotate. Similarly, when the torque performance of the ball head is normal, the ball head will not be deformed, and the power assembly will not apply a certain power torque to gear 10 to cause gear 10 to rotate.

[0039] like Figures 3 to 5 As shown, the power assembly includes a dual-output motor 19, one end of the output shaft of the dual-output motor 19 is fixedly connected to a transmission ring 20, the outer wall of the transmission ring 20 is transmission-connected to a transmission belt 21, the other end of the transmission belt 21 is transmission-connected to a transmission ring 22 on the inner wall, one side of the transmission ring 22 is fixedly connected to a rotating rod 23, one side of the rotating rod 23 is fixedly connected to a gear 25, and the teeth of the gear 25 are meshed with the teeth of the gear 10.

[0040] When working: the dual-output motor 19 is the power source for applying torque to the ball head. The dual-output motor 19 is set to a certain power and transmitted to the transmission ring 22 through the transmission ring 1 20 and the transmission belt 1 21. The transmission ring 22 will be transmitted to the gear 2 25 through the rotating rod 23, and the gear 25 will be transmitted to the clamping pad 5 through the gear 1 10, so that the clamping pad 5 applies torque to the ball head. When the ball head is deformed by the torque, all the structures of the power assembly will operate, indicating that the torque performance of the ball head is poor. When the ball head is not deformed by the torque, all the structures of the power assembly will not operate, and the torque performance of the ball head is normal.

[0041] like Figures 3 to 5 As shown, the push-pull assembly includes an open seat 15, which is fixedly installed on the top of the test bench 1, and the outer side of the open seat 15 is fixedly connected with a clamping member 24, the outer wall of the rotating rod 23 is rotatably connected to the inner wall of the clamping member 24, the inner wall of the open seat 15 is rotatably connected with a screw rod 16, the outer wall of the screw rod 16 is threadedly connected with a push block 17, the outer wall of the push block 17 is slidably connected to the inner wall of the open seat 15, one end of the push block 17 is fixedly connected with a push ball 18, the outer wall of the push ball 18 is fitted with the outer wall of the ball head, and one end of the screw rod 16 is fixedly connected to the output shaft at the other end of the dual-output motor 19.

[0042] During operation: when one end of the dual-output motor 19 applies torque, the other end applies thrust. When the other end of the dual-output motor 19 applies rotational force to the screw 16, the screw 16 will apply thrust to the push ball 18 through the push block 17. Since the outer wall of the push ball 18 fits with the outer wall of the ball head, the thrust exerted on the push ball 18 will be applied to the outer wall of the ball head, exerting thrust on the outer wall of the ball head. When the ball head is deformed by the thrust, the push ball 18 will be pushed forward, and the push block 17 will also be pushed forward, so the screw 16 will rotate, indicating that the thrust performance of the ball head is poor. When the ball head is not deformed by the thrust, all structures of the push-pull assembly will not operate, and the torque performance of the ball head is normal.

[0043] like Figures 6 to 8 As shown, the two groups of marking components include a pigment bin 27, the inner wall of the pigment bin 27 is fitted with a blocking block 28, the outer wall of the blocking block 28 is fixedly connected to a connecting rod 26, the outer wall of the connecting rod 26 is rotatably connected to a clamping member 2 31, the clamping member 2 31 is fixedly installed on the top of the test bench 1, one side of the pigment bin 27 is fixedly connected to a flow tube 29, one end of the flow tube 29 is fixedly connected to a nozzle 30, a transmission assembly is arranged between one group of marking components and the power assembly, and a linkage assembly is arranged between the other group of marking components and the push-pull assembly.

[0044] During operation: when the torque component performs a torque test on the ball head, after the ball head is deformed by the torque, the power component will operate, and the power component will drive one of the connecting rods 26 to rotate through the transmission component. After the connecting rod 26 rotates, the pigment in the pigment bin 27 will not be blocked, and the pigment will be sprayed onto the outer wall of the ball head through the flow tube 29 and the nozzle 30, so as to achieve the purpose of marking. When the ball head is not deformed by the torque, the connecting rod 26 is always in a blocked state and cannot be marked. Similarly, when the ball head is deformed by the thrust, the thrust component will drive the other connecting rod 26 to rotate through the linkage component, so as to also mark. When the ball head is not deformed by the thrust, the connecting rod 26 is always in a blocked state and cannot be marked.

[0045] like Figures 6 to 8 As shown, the colors of the pigments placed in the two pigment bins 27 are different, and the openings of the two nozzles 30 are both aligned with the outer wall of the ball head.

[0046] During operation: the two paint bins 27 are set to paints of different colors. After the ball head is subjected to torque and thrust, different marking operations can be performed according to different deformation conditions. After the detection is completed, the results of the ball head torque performance and thrust performance tests can be directly judged by the marking conditions.

[0047] like Figure 6 As shown, the transmission assembly includes a gear five 34, the teeth of the gear five 34 are meshed with a gear six 35, one end of the shaft of the gear six 35 is fixedly connected to a transmission ring three 36, the outer wall of the transmission ring three 36 is transmission-connected to a transmission belt two 37, the other end of the transmission belt two 37 is transmission-connected to a transmission ring four 38, the transmission ring four 38 is fixedly connected to one end of one of the connecting rods 26, the outer wall of the shaft of the gear six 35 is transmission-connected to a clamping member three 39, and one side of the clamping member three 39 is fixedly connected to one side of the clamping member one 24.

[0048] During operation: when the torque performance of the ball head is poor and it is deformed by the torque, the rotating rod 23 will rotate, and the rotating rod 23 will drive the gear five 34 to rotate, and drive the transmission ring four 38 to rotate through the gear six 35, the transmission ring three 36 and the transmission belt two 37, so that one of the connecting rods 26 is rotated, so that the torque test mark of the ball head is performed.

[0049] like Figure 6 As shown, the linkage assembly includes a gear four 33, which is fixedly connected to the outer wall of the screw rod 16, and the teeth of the gear four 33 are meshed with the gear three 32, and the gear three 32 is fixedly connected to one end of another connecting rod 26.

[0050] During operation: when the thrust performance of the ball head is poor and it is deformed by the thrust, the screw rod 16 will rotate, and the screw rod 16 drives the gear three 32 to rotate through the gear four 33, so that another connecting rod 26 is rotated, so that the ball head is marked for thrust test.

[0051] Working process: First, the ball head and the ball head connector are fixedly installed on the top of the test bench 1 through the cooperation of the threaded rod and the threaded inner hole 3, and the two electromagnets 8 are passed with current. Since the two electromagnets 8 are in parallel and the magnetic fields of the surfaces close to each other are of opposite poles, the two electromagnets 8 are combined and connected together. At this time, the electromagnets 8 can make the two clamping pads 5 fit tightly against the outer wall of the ball head through the connector 7, thereby tightly fitting the outer wall of the ball head to achieve the clamping effect on the ball head. After the torque test of the ball head is completed through the reset spring 11, the current passed by the electromagnet 8 is turned off, so that the two electromagnets 8 have no magnetic properties, and the clamping pads 5 can be restored to their original position through the reset spring 11, and the electromagnet 8 can also be reset during the resetting process of the clamping pads 5, which is convenient for removing the ball head while also facilitating preparation for the torque test of the next ball head.

[0052] Secondly, the dual-output motor 19 is the power source for applying torque to the ball head. The dual-output motor 19 sets a certain power and transmits it to the transmission ring 22 through the transmission ring 1 20 and the transmission belt 1 21. The transmission ring 22 will transmit it to the gear 2 25 through the rotating rod 23, and the gear 25 will transmit it to the clamping pad 5 through the gear 1 10, so that the clamping pad 5 applies torque to the ball head. When the ball head is deformed by the torque, all the structures of the power assembly will operate, indicating that the torque performance of the ball head is poor. When the ball head is not deformed by the torque, all the structures of the power assembly will not operate. At this time, the torque performance of the ball head is normal. While one end of the motor 19 applies torque, the other end applies thrust. When the other end of the dual-output motor 19 applies rotational force to the screw 16, the screw 16 will apply thrust to the push ball 18 through the push block 17. Since the outer wall of the push ball 18 fits with the outer wall of the ball head, the thrust exerted on the push ball 18 will be applied to the outer wall of the ball head, exerting thrust on the outer wall of the ball head. When the ball head is deformed by the thrust, the push ball 18 will be pushed forward, and the push block 17 will also be pushed forward, so the screw 16 will rotate, indicating that the thrust performance of the ball head is poor. When the ball head is not deformed by the thrust, all structures of the push-pull assembly will not operate, and the torque performance of the ball head is normal.

[0053] Then, when the torsion assembly performs a torque test on the ball head, after the ball head is deformed by the torque, the rotating rod 23 will rotate, and the rotating rod 23 will drive the gear five 34 to rotate, and drive the transmission ring four 38 to rotate through the gear six 35, the transmission ring three 36 and the transmission belt two 37, so that one of the connecting rods 26 is rotated. After the connecting rod 26 rotates, the pigment in the pigment bin 27 will not be blocked, and it will be sprayed onto the outer wall of the ball head through the flow tube 29 and the nozzle 30 to achieve the purpose of marking. When the ball head is not deformed by the torque, the connecting rod 26 is always in a blocked state and cannot be marked.

[0054] When the thrust performance of the ball head is poor and it is deformed by the thrust, the screw rod 16 will rotate, and the screw rod 16 will drive the gear three 32 to rotate through the gear four 33, so that the other connecting rod 26 will rotate, and thus marking will also be performed. When the ball head is not deformed by the thrust, the connecting rod 26 is always in a blocked state and cannot be marked.

[0055] The two pigment bins (27) are set with pigments of different colors. After the ball head is subjected to torque and thrust, different marking operations can be performed according to different deformation conditions. After the detection is completed, the results of the ball head torque performance and thrust performance test can be directly judged by the marking conditions.
