Description

Technical Field

[0001] This utility model relates to the field of thrust rod detection technology, and in particular to a composite angle measuring tool for thrust rod brackets. Background Technology

[0002] Thrust rods are mainly used in the suspension systems of heavy-duty trucks or buses with single or double rear axles, connecting the frame and the axle. Their purpose is to overcome the limitations of leaf springs, which can only transmit vertical and lateral forces but not traction, braking force, and their corresponding reaction torque. They are an indispensable part of automobiles. During the production process, to ensure production quality, the composite angle of the thrust rod bracket is generally tested.

[0003] Currently, most methods for measuring the composite angle of thrust rod supports use coordinate measuring machines (CMMs). This method requires operators to place the thrust rod support on the measuring platform, adjust its position, and then use the measuring machine to perform the measurement. This is not only inefficient for measuring the composite angle of the thrust rod support, but also costly, thus affecting production efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a composite angle measuring tool for a thrust rod support.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A composite angle measuring instrument for a thrust rod bracket includes a circular frame with four ejector holes on its surface. Two measuring components are rotatably connected to the surface of the circular frame. Each measuring component includes a first circular ring and a second circular ring, a pointer fixedly connected to the upper surfaces of the first and second circular rings, a first strip plate and a second strip plate fixedly connected to the surfaces of the first and second circular rings, a connecting rod fixedly connected to the lower surfaces of the first and second strip plates, an arc-shaped clamping frame fixedly connected to the bottom end of the connecting rod, and a scale fixedly connected to the upper surface of the circular frame. A locking component is rotatably connected to the lower surface of the circular frame.

[0007] Preferably, the height of the first strip plate is higher than the height of the second strip plate, and the length of the connecting rod on the lower surface of the first strip plate is greater than the length of the connecting rod on the lower surface of the second strip plate, and the heights of the two arc-shaped clamping frames are the same.

[0008] Preferably, the side of the arc-shaped clamping frame is rotatably connected to a positive and negative threaded rod, and the inner top wall of the arc-shaped clamping frame is provided with a sliding groove. The inner top wall of the sliding groove is slidably connected to two movable plates, and the two movable plates are respectively threaded to the positive and negative threads on the surface of the positive and negative threaded rod.

[0009] Preferably, a positioning plate is fixedly connected to the lower surface of each of the two movable plates, and an arc-shaped locking plate is fixedly connected to the opposite surface of the two positioning plates.

[0010] Preferably, the locking assembly includes a circular rod, the top of which is rotatably connected to the inner top wall of the circular frame, and two transverse bevel gears are fixedly connected to the surface of the circular rod. Strip frames are fixedly connected to the inner top and bottom walls of the circular frame. Through holes are opened on the upper surfaces of the two strip frames, and movable grooves are opened on the left and right inner walls of the two through holes. Threaded rods are rotatably connected to the inner walls of the movable grooves. Each pair of corresponding threaded rods forms a group, and vertical bevel gears are fixedly connected to the opposite ends of each group of threaded rods. Each group of vertical bevel gears meshes with two transverse bevel gears respectively.

[0011] Preferably, the inner wall of the movable groove is slidably connected to a movable plate, the movable plate is threadedly connected to a threaded rod, and two push rods are fixedly connected to the opposite sides of each set of movable plates. Fixed grooves are opened on the left and right sides of the two strip frames, and the positions of the fixed grooves correspond to the positions of the ejector holes. A top plate is slidably connected to the inner bottom wall of the fixed groove. The end of the push rod away from the movable plate is fixedly connected to the top plate, and a push pin is fixedly connected to the side of the top plate away from the push rod.

[0012] The beneficial effects of this utility model are as follows:

[0013] The first and second circular rings can drive the first and second strip plates to rotate around the surface of the circular frame, thereby rotating them to a state parallel to the two supports of the thrust rod. At this time, the two supports are locked by two sets of arc-shaped locking plates. The position of the pointers above the first and second circular rings on the dial can be used to quickly measure the size of the composite angle of the supports, with high measurement efficiency and accuracy. Furthermore, the circular rod and two transverse bevel gears can be used to drive the four pins to move outwards from the circular frame, thereby pressing against the inner walls of the first and second circular rings to lock the position of the pointers. After the arc-shaped locking plates are removed, it can be ensured that the position of the pointers on the dial will not shift, resulting in higher stability. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example:

[0020] Reference Figure 1-3 A composite angle measuring tool for a thrust rod bracket includes a circular frame 1. The surface of the circular frame 1 has four ejector holes. Two measuring components are rotatably connected to the surface of the circular frame 1. The measuring components include a first circular ring 2 and a second circular ring 3, a pointer 4 fixedly connected to the upper surface of the first circular ring 2 and the second circular ring 3, a first strip plate 5 and a second strip plate 6 fixedly connected to the surface of the first circular ring 2 and the second circular ring 3, a connecting rod 7 fixedly connected to the lower surface of the first strip plate 5 and the second strip plate 6, an arc-shaped clamping frame 8 fixedly connected to the bottom end of the connecting rod 7, and a scale 9 fixedly connected to the upper surface of the circular frame 1. A locking component is rotatably connected to the lower surface of the circular frame 1.

[0021] The height of the first strip plate 5 is higher than the height of the second strip plate 6, and the length of the connecting rod 7 on the lower surface of the first strip plate 5 is greater than the length of the connecting rod 7 on the lower surface of the second strip plate 6. The two arc-shaped clamping frames 8 have the same height. The sides of the arc-shaped clamping frames 8 are rotatably connected with positive and negative threaded rods 10. The inner top wall of the arc-shaped clamping frame 8 is provided with a sliding groove. The inner top wall of the sliding groove is slidably connected with two movable plates 11. The two movable plates 11 are respectively threaded to the positive and negative threads on the surface of the positive and negative threaded rods 10. The lower surfaces of the two movable plates 11 are fixedly connected with positioning plates 12. The opposite surfaces of the two positioning plates 12 are fixedly connected with arc-shaped locking plates 13.

[0022] The first circular ring 2 and the second circular ring 3 are used to drive the first strip plate 5 and the second strip plate 6 to keep parallel to the two supports of the thrust rod. At this time, the two sets of arc-shaped locking plates 13 are locked on the surface of the support, and the positive and negative threaded rods 10 are rotated. The two movable plates 11 move to the opposite face, driving the two positioning plates 12 and the arc-shaped locking plates 13 to press the surface of the support tightly. At this time, the pointer 4 above the first circular ring 2 and the second circular ring 3 can cooperate with the scale 9 to measure the size of the composite angle of the support, which is more accurate.

[0023] The locking assembly includes a circular rod 14, the top of which is rotatably connected to the inner top wall of the circular frame 1. Two transverse bevel gears 15 are fixedly connected to the surface of the circular rod 14. Strip frames 16 are fixedly connected to the inner top and bottom walls of the circular frame 1. Through holes are formed on the upper surfaces of the two strip frames 16, and movable grooves are formed on the left and right inner walls of the two through holes. Threaded rods 17 are rotatably connected to the inner walls of the movable grooves. Each pair of corresponding threaded rods 17 forms a group. Vertical bevel gears 18 are fixedly connected to the opposite ends of each group of threaded rods 17. The vertical bevel gear 18 meshes with two horizontal bevel gears 15 respectively. The inner wall of the movable groove is slidably connected with a movable plate 19. The movable plate 19 is threadedly connected with the threaded rod 17. Two push rods 20 are fixedly connected to the opposite side of each set of movable plates 19. Fixed grooves are opened on the left and right sides of the two strip frames 16, and the position of the fixed grooves corresponds to the position of the ejection hole. The inner bottom wall of the fixed groove is slidably connected with a top plate 21. The end of the push rod 20 away from the movable plate 19 is fixedly connected to the top plate 21. The side of the top plate 21 away from the push rod 20 is fixedly connected with a push pin 22.

[0024] After confirming the position of the composite angle measurement of the thrust rod bracket using pointer 4 and dial 9, rotate the circular rod 14. The circular rod 14 drives two sets of vertical bevel gears 18 to rotate through two horizontal bevel gears 15, thereby driving the moving plate 19 to move to both sides through the threaded rod 17. The moving plate 19, through the cooperation of the top rod 20 and the top plate 21, drives the top pin 22 to move to the outside of the circular frame 1. The top pin 22 can press against the inner wall of the first circular ring 2 and the second circular ring 3, thereby locking the position of the first circular ring 2 and the second circular ring 3, ensuring that the first circular ring 2 and the second circular ring 3 will not shift after the arc-shaped locking plate 13 is removed, thus improving stability.

[0025] Working principle: First, align the two arc-shaped clamping frames 8 with the surface of the thrust rod bracket. Then, align the two sets of arc-shaped locking plates 13 with the bracket shaft. Rotate the two positive and negative threaded rods 10. At this time, the two movable plates 11 can drive the two positioning plates 12 and the arc-shaped locking plates 13 to move towards the opposite surface, thereby clamping the surface of the thrust rod bracket through the two arc-shaped locking plates 13. Meanwhile, the first strip plate 5 and the second strip plate 6 drive the first circular ring 2 and the second circular ring 3 to fix their positions on the surface of the circular frame 1. Using the two pointers 4 and the scale 9 on the upper surface of the first strip plate 5 and the second strip plate 6, it is possible to check whether the composite angle of the bracket meets the standard. This design offers high flexibility and is applicable to different composite angles. With the thrust rod bracket of the angle size, after the positions of the first strip plate 5 and the second strip plate 6 are confirmed, the circular rod 14 at the bottom of the circular frame 1 is rotated. The circular rod 14 drives the two horizontal bevel gears 15 to rotate, and the two horizontal bevel gears 15 drive the two vertical bevel gears 18 to rotate, thereby driving the four threaded rods 17 to rotate. At this time, the moving plate 19 drives the ejector pin 22 to move outward of the circular frame 1 through the push rod 20 and the top plate 21. The ejector pin 22 can press against the inner wall of the first circular ring 2 and the second circular ring 3, so the positions of the first circular ring 2 and the second circular ring 3 can be locked. At this time, the position of the pointer 4 will not shift after the arc-shaped locking plate 13 is removed, and the stability is higher.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
