Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a thrust spacer profile measuring fixture. Background Technology

[0002] In mechanical transmission systems, such as automotive gearboxes, machine tool spindles, and motor bearings, the thrust spacer is a key component for controlling axial clearance and transmitting axial force. Its profile accuracy directly determines the transmission efficiency and equipment lifespan.

[0003] In the existing process of thrust spacer sleeve contour inspection, the fixture design has significant defects, making it difficult to meet the quality control requirements of large-scale production. Traditional thrust spacer sleeve contour inspection process can usually only detect one side of the thrust spacer sleeve. Since the thrust spacer sleeve is a ring structure, it is usually necessary to rotate the angle and re-fix it when inspecting its side contour. Therefore, multiple disassembly and fixation are required to complete the side inspection, resulting in low inspection efficiency. Utility Model Content

[0004] In view of the problems existing in the detection of thrust spacers, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a thrust spacer profile measuring instrument inspection fixture, which solves the problem that existing thrust spacers usually need to be rotated continuously to complete the complete inspection of the side profile of the thrust spacer, and each disassembly and rotation and fixing takes a long time, thus reducing the inspection efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A thrust spacer profile measuring fixture includes a base, an L-shaped plate fixedly connected to the upper surface of the base, a profile measuring instrument fixedly connected to the lower surface above the L-shaped plate, a fixing block fixedly connected to the upper surface of the base, an arc-shaped groove formed on the upper surface of the fixing block, a thrust spacer placed inside the arc-shaped groove, a strip block fixedly connected to one side of the fixing block, a strip groove formed on the upper surface of the strip block, an L-shaped moving plate slidably disposed inside the strip groove, a pressure block fixedly connected to the lower surface of the L-shaped moving plate, the thrust spacer fixed by the pressure block, a fixing mechanism provided on one side of the strip block, the L-shaped moving plate fixed by the fixing mechanism, a first circular groove formed inside the arc-shaped groove, a rotating rod rotatably connected inside the first circular groove, the rod wall fixedly sleeved on a rubber wheel, the rubber wheel fitting against the thrust spacer.

[0007] Preferably, the fixing mechanism includes a fixing frame, a stop block, a plug rod, a pull ring, and a spring. The fixing frame is fixedly connected to one side of the strip block. A through hole is opened on one side of the fixing frame. The plug rod is slidably disposed inside the through hole. The stop block is fixedly sleeved on the rod wall of the plug rod. The pull ring is fixedly connected to one end of the plug rod. The spring is slidably sleeved on the rod wall of the plug rod.

[0008] Preferably, the L-shaped movable plate has multiple slots on one side.

[0009] Preferably, one end of the insert extends through one side of the strip block and matches each slot.

[0010] Preferably, a motor is fixedly connected to one side of the fixing block, and one end of the rotating rod passes through one side of the first circular groove and is fixedly connected to the output end of the motor.

[0011] Preferably, the lower end of the pressure block is arc-shaped and matches the thrust spacer sleeve.

[0012] Preferably, the arc-shaped groove has two symmetrical second circular grooves inside, and each of the two second circular grooves is rotatably connected to an auxiliary rotating wheel.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model uses a motor to drive a rubber wheel to rotate a thrust spacer sleeve smoothly. With the help of an auxiliary rotating wheel in the arc groove, it can achieve 360° all-round contour detection. Compared with the traditional detection method of multiple disassemblies and rotation fixation, it does not require interruption of the detection process, thereby improving the detection efficiency.

[0014] 2. This utility model can quickly achieve workpiece center positioning through the arc groove of the fixing block, which reduces the deviation rate compared to manual positioning; at the same time, the arc design of the lower end of the pressure block, combined with the smooth surface treatment, ensures uniform distribution of clamping force, which not only prevents the workpiece from moving up and down when rotating, but also avoids workpiece deformation caused by traditional rigid clamping.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model discloses a thrust spacer profile measuring instrument inspection fixture.

[0020] This utility model provides, for example Figure 1-4 The thrust spacer profile measuring fixture shown includes a base 1, an L-shaped plate 2 fixedly connected to the upper surface of the base 1, a profile measuring instrument 3 fixedly connected to the lower surface above the L-shaped plate 2, a fixing block 4 fixedly connected to the upper surface of the base 1, an arc-shaped groove on the upper surface of the fixing block 4, a thrust spacer 5 placed inside the arc-shaped groove, a strip block 6 fixedly connected to one side of the fixing block 4, a strip groove on the upper surface of the strip block 6, an L-shaped moving plate 7 slidably arranged inside the strip groove, a pressure block 8 fixedly connected to the lower surface of the L-shaped moving plate 7, the thrust spacer 5 being fixed by the pressure block 8, a fixing mechanism on one side of the strip block 6, the L-shaped moving plate 7 being fixed by the fixing mechanism, a first circular groove inside the arc-shaped groove, a rotating rod 14 rotatably connected inside the first circular groove, the rod wall of the rotating rod 14 being fixedly sleeved on a rubber wheel 15, the rubber wheel 15 fitting against the thrust spacer 5, and the lower end of the pressure block 8 being arc-shaped and matching the thrust spacer 5.

[0021] The thrust spacer sleeve 5 is placed in the arc-shaped groove of the fixed block 4. The curvature of the arc-shaped groove matches the outer circle of the thrust spacer sleeve, which can quickly achieve the center positioning of the workpiece and avoid the detection deviation caused by manual adjustment. The side inspection can be completed without multiple disassembly and fixing, which can greatly improve the inspection efficiency. At the same time, the arc-shaped groove provides circumferential support for the workpiece and prevents the workpiece from radially shifting during rotation inspection. The L-shaped moving plate 7 is pushed along the strip groove of the strip block 6, which drives the pressure block 8 to move towards the thrust spacer sleeve 5 until the arc-shaped surface of the lower end of the pressure block is completely in contact with the upper surface of the thrust spacer sleeve. The lower surface of the pressure block is smoothed to allow it to move while preventing the thrust spacer sleeve from moving up and down.

[0022] like Figure 1-4 As shown, the fixing mechanism includes a fixing frame 9, a stop block 10, a plug rod 11, a pull ring 12, and a spring 13. The fixing frame 9 is fixedly connected to one side of the strip block 6. A through hole is opened on one side of the fixing frame 9. The plug rod 11 is slidably disposed inside the through hole. The stop block 10 is fixedly sleeved on the rod wall of the plug rod 11. The pull ring 12 is fixedly connected to one end of the plug rod 11. The spring 13 is slidably sleeved on the rod wall of the plug rod 11. A plurality of slots are opened on one side of the L-shaped moving plate 7. One end of the plug rod 11 passes through one side of the strip block 6 and matches each slot.

[0023] After the pressure block 8 clamps the workpiece, the pull ring 12 is released, the elastic potential energy of the spring 13 is released, and the stop block 10 is pushed to drive the insertion rod 11 to slide along the through hole of the fixed frame 9, so that one end of the insertion rod passes through the strip block 6 and is inserted into the slot of the L-shaped moving plate 7. The cooperation between the insertion rod and the slot restricts the movement of the L-shaped moving plate and locks the clamping state of the pressure block. By opening multiple slots to cooperate with the insertion rod, it is convenient to fix spacer sleeves of different sizes.

[0024] like Figure 1-2 As shown, a motor 16 is fixedly connected to one side of the fixing block 4, and one end of the rotating rod 14 passes through one side of the first circular groove and is fixedly connected to the output end of the motor 16.

[0025] When the motor 16 is started, the output end drives the rotating rod 14 to rotate in the first circular groove of the fixed block 4. The rubber wheel 15 on the rod wall rotates synchronously with the rotating rod. The rubber wheel is in contact with the outer surface of the thrust spacer 5. Through friction, the thrust spacer rotates in the arc groove. The high coefficient of friction of the rubber wheel can prevent slippage and ensure that the workpiece and the rubber wheel rotate synchronously.

[0026] like Figure 1-2 As shown, there are two symmetrical second circular grooves inside the arc-shaped groove, and each of the two second circular grooves is rotatably connected to an auxiliary rotating wheel 17.

[0027] Two auxiliary rotating wheels 17 are symmetrically arranged inside the arc groove and fit against the outer surface of the thrust spacer sleeve 5. On the one hand, they can support the weight of the workpiece and prevent the lower surface of the workpiece from being worn due to its own weight; on the other hand, the auxiliary rotating wheels rotate synchronously with the workpiece, reducing the frictional resistance between the workpiece and the arc groove and ensuring that the workpiece rotates smoothly without jamming.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
