Description

Technical Field

[0001] This invention relates to a storage and measuring device for the main cone gasket of an automotive main reducer, belonging to the technical field of automotive parts production equipment. Background Technology

[0002] In the automotive main reducer manufacturing industry, the main cone gaskets for automotive main reducers come in various models with the same outer diameter but different thicknesses. During production, to prevent misassembly, each main cone gasket needs to be individually measured for thickness before being categorized and stored. Currently available gasket measuring devices, such as the thickness gauge disclosed in utility model patent CN2108238784U, measure gasket thickness using the principle of ultrasonic reflection. While this can meet the general needs of gasket thickness measurement to a certain extent, the main cone gaskets for automotive main reducers have a circular structure. During testing, the surface of the main cone gasket may not be perfectly level. Therefore, when using a thickness gauge, inconsistent measurement data at different locations on the main cone gasket can lead to poor measurement accuracy. Thus, it is necessary to develop a new storage and measuring device for automotive main reducer main cone gaskets to solve the above-mentioned problems with existing measurement methods.

[0028] The storage and measurement device for the main cone gasket of the automotive final drive includes a measuring device 1, a storage mechanism 2, and a transfer robot (see the attached instruction manual). Figure 1 and 9 ).

[0029] A transfer robot (not shown in the attached diagram of the manual) is installed between the measuring device 1 and the storage mechanism 2. When the transfer robot is an externally purchased device, it can place the workpiece that has been inspected on the measuring device 1 onto the storage mechanism 2 for storage.

[0030] Measuring device 1 includes frame 3, rotary table 4, storage cylinder 6, push-pull cylinder 15, sliding seat 10, lifting cylinder 7, and detection probe 8 (see instruction manual appendix). Figure 1 , 2 and 3).

[0031] A rotating disk 4 is mounted on the frame 3 via a rotating cylinder; multiple sets of storage cylinders 6 are symmetrically mounted on the rotating disk 4 via support bases 5. The rotating cylinder can drive the rotating disk 4 to rotate 180° in one operation.

[0032] The support base 5 is provided with a clearance groove 27; a storage cylinder 6 is fixedly mounted on the support base 5 at the upper end of the clearance groove 27; a discharge opening 28 is provided at the lower end of the storage cylinder 6; an observation opening 29 is provided on one side of the storage cylinder 6 (see the appendix of the instruction manual). Figure 12 The purpose of setting up the support base 5 and the storage cylinder 6 in this way is to enable the hook 16 to be inserted into the bottom of the storage cylinder 6 through the clearance groove 27 during operation, and to hook the main cone pad at the bottom of the storage cylinder 6 and then pull the support base 5 out through the discharge opening 28.

[0033] The purpose of symmetrically installing multiple sets of storage cylinders 6 on the rotating disk 4 via support bases 5 is to ensure that, during operation, after the hook 16 has hooked and removed the workpiece inside the storage cylinder 6 facing the sliding seat 10, the rotating cylinder can rotate the rotating disk 4 180° once to allow the storage cylinder 6 on the other side, which is full of workpieces, to face the sliding seat 10 and continue operating. This achieves the goal of continuously supplying workpieces.

[0034] A detection probe 8 is mounted on the frame 3 at one end of the rotating disk 4 via a lifting cylinder 7 (see instruction manual appendix). Figure 3 and 4 When the lifting cylinder 7 is working, it can drive the detection probe 8 to move up and down.

[0035] The detection probe 8 includes a displacement sensor 21, a base 17, a limiting ring 18, a movable ball seat 19, a detection sleeve 20, a detection probe 22, a return spring 24, and a guide sleeve 23 (see the instruction manual appendix). Figure 5 ).

[0036] The piston rod end of the lifting cylinder 7 is connected to the base 17; a movable ball seat 19 is movably mounted inside the base 17 via a limiting ring 18 (see the instruction manual appendix). Figure 5 The lower end of the movable ball seat 19 extends below the limiting ring 18.

[0037] The limiting ring 18 confines the movable ball seat 19 within the base 17, thus preventing the movable ball seat 19 from detaching from the base 17. A connecting spherical surface 26 is provided on the upper end face of the movable ball seat 19; the movable ball seat 19 is connected to the base 17 via the connecting spherical surface 26. A certain gap exists between the stepped surface of the movable ball seat 19 and the inner surface of the limiting ring 18, allowing the movable ball seat 19 to rotate relative to the base 17 under the action of the connecting spherical surface 26 when subjected to force.

[0038] A detection sleeve 20 is fixedly installed inside the movable ball seat 19; the upper end of the detection sleeve 20 extends above the base 17 and is fitted with a displacement sensor 21.

[0039] A detection probe 22 with a "T"-shaped structure is movably mounted on the detection sleeve 20 below the displacement sensor 21; the lower end of the detection probe 22 extends to the bottom of the detection sleeve 20. When the detection probe 22 is subjected to force, it can only slide up and down along the inner wall of the detection sleeve 20.

[0040] A guide sleeve 23 is movably mounted inside the detection sleeve 20 above the detection probe 22; an inner flange is provided on the lower end face of the guide sleeve 23; a return spring 24 is provided between the inner flange of the guide sleeve 23 and the upper end of the detection sleeve 20. The guide sleeve 23 is in contact with the upper end of the detection probe 22; thus, under the action of the elastic force of the return spring 24, the guide sleeve 23 will compress the detection probe 22, causing it to always have a downward tendency.

[0041] The upper end face of the detection probe 22 is in contact with the displacement sensor 21 (see the instruction manual appendix). Figure 5 During the upward movement of the detection probe 22 relative to the detection sleeve 20 under force, the detection probe 22 will squeeze the guide sleeve 23 to overcome the elastic force of the return spring 24 and move upward. At the same time, the detection probe 22 will squeeze the displacement sensor 21 to achieve the purpose of recording the displacement stroke of the detection probe 22.

[0042] The lower end of the detection sleeve 20 is provided with a reference detection surface 25 (see the instruction manual appendix). Figure 5 During operation, when the reference detection surface 25 contacts the upper surface of the detection block 11, the detection probe 22 abuts against the bottom of the detection groove 30 of the detection block 11 to obtain a displacement value; when the reference detection surface 25 contacts the upper surface of the workpiece, the detection probe 22 abuts against the bottom of the detection groove 30 of the detection block 11 to obtain another displacement value; the difference between the two sets of displacement values ​​is the thickness of the workpiece, thus achieving the purpose of measuring the thickness of the workpiece.

[0043] A sliding seat 10 is mounted on the frame 3 below the detection probe 8 via a guide rail and a drive screw 9 (see instruction manual appendix). Figure 1 and 2When the lead screw 9 is working, it can drive the sliding seat 10 to slide back and forth along the guide rail.

[0044] A detection block 11 is fixedly mounted on the sliding seat 10; the detection block 11 is provided with a detection groove 30 (see the instruction manual). Figure 8 ).

[0045] A positioning plate 12 is fixedly mounted on one side of the detection block 11; a limiting plate 14 is mounted on the other side of the detection block 11 via a limiting cylinder 13; the limiting plate 14 is provided with a "V-shaped" limiting port. During operation, when the workpiece is located on the detection block 11 between the limiting plate 14 and the positioning plate 12, the limiting plate 14 can clamp and fix the workpiece through the "V-shaped" limiting port in cooperation with the positioning plate 12.

[0046] One end of the detection block 11 is equipped with a pull hook 16 via a push-pull cylinder 15 and a torsion spring (see instruction manual appendix). Figure 6 , 7 (and 8). When the hook 16 is compressed, it can overcome the elastic force of the torsion spring and move downward. After resetting under the action of the elastic force, it hooks the workpiece.

[0047] The storage mechanism 2 includes a base 31, an indexing motor, and a storage rack 32. The storage rack 32 is mounted on the base 31 via the indexing motor. Multiple storage surfaces are provided on the surface of the storage rack 32. Multiple storage plates 33 are spaced vertically on each storage surface. Multiple pick-and-place openings 34 are spaced vertically on each storage plate 33. Multiple limit pins 35 are installed on the storage plates 33 surrounding the pick-and-place openings 34. During operation, a transfer robot can pick up the workpiece that has been inspected on the measuring device 1 and place it between the limit pins 35 through the pick-and-place openings 34 (see the attached instruction manual). Figure 11 ).

[0048] When the storage and measuring device for the main cone shim of the automotive main reducer is working, the drive screw 9 first drives the sliding seat 10 to move below the detection probe 8. The lifting cylinder 7 drives the detection probe 8 to move downward. When the reference detection surface 25 contacts the upper end surface of the detection block 11, the detection probe 8 stops moving downward. During this process, the detection probe 22 comes into contact with the bottom of the detection groove 30 of the detection block 11. The detection probe 22 then squeezes the guide sleeve 23 to overcome the elastic force of the return spring 24 and moves upward. At the same time, the detection probe 22 will squeeze the displacement sensor 21 to record a displacement value A.

[0049] After the above actions are completed, the lifting cylinder 7 drives the detection probe 8 to reset; then the drive screw 9 first drives the sliding seat 10 to move to correspond with the corresponding storage cylinder 6. Then the push-pull cylinder 15 pushes the hook 16 through the clearance groove 27 to insert into the bottom of the storage cylinder 6. During this process, the workpiece (main cone washer) inside the storage cylinder 6 will be pushed downward by the upper end of the hook 16 to overcome the torsion spring force. When the hook of the hook 16 moves to the inside of the workpiece (main cone washer), the hook 16 can reset under the torsion spring force and hook the workpiece.

[0050] After the hook 16 hooks the workpiece, the push-pull cylinder 15 pulls the workpiece onto the detection block 11 via the hook 16. At this time, the workpiece is located between the limiting plate 14 and the positioning plate 12. Subsequently, the limiting plate 14 moves and clamps and fixes the workpiece through the "V-shaped" limiting port with the cooperation of the positioning plate 12.

[0051] After the workpiece is clamped and fixed, the drive screw 9 first drives the sliding seat 10 to move below the detection probe 8. Then, the lifting cylinder 7 moves the detection probe 8 downwards. When the reference detection surface 25 contacts the upper surface of the workpiece (main cone pad), if the upper surface of the workpiece is not completely level, the workpiece can press the movable ball seat 19 through the reference detection surface 25, causing it to rotate relative to the base 17 under the action of the connecting ball surface 26. This allows the reference detection surface 25 to come into contact with the upper surface of the workpiece (main cone pad) as the movable ball seat 19 rotates, at which point the detection probe 8 stops moving downwards. During this process, the detection probe 22 contacts the bottom of the detection groove 30 of the detection block 11. The detection probe 22 then presses the guide sleeve 23 to overcome the elastic force of the return spring 24 and move upwards. At the same time, the detection probe 22 will press the displacement sensor 21 to record a displacement value B. After detecting the value B, the lifting cylinder 7 moves the detection probe 8 upwards to reset. The difference between value B and value A is then calculated to obtain the thickness of the workpiece.

[0052] After the above process is completed, the limiting plate 14 releases the workpiece, and then the transfer robot will place the workpiece, which has been inspected on the measuring device 1, between the corresponding limiting pins 35 on the storage mechanism 2 through the pick-and-place port 34 (see the instruction manual appendix). Figure 11 At this point, the storage and measuring device for the main cone gasket of the automotive main reducer has completed the measurement and storage of the workpiece, and the storage and measuring device can then enter the next work cycle.

[0053] The storage and measurement device for the main cone gasket of the automotive main reducer is compact and ingeniously designed. It can measure the thickness of the main cone gasket through the displacement sensor 21, thereby solving the problem of poor detection accuracy in the existing measurement methods for the main cone gasket of the automotive main reducer and meeting the storage and use needs of the main cone gasket of the automotive main reducer.
