Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an automobile parts inner hole inspection tool with a rotating mechanism. Background Art

[0002] Gauges are simple tools used by industrial manufacturers to control various dimensions of products (such as aperture, space dimensions, etc.) to improve production efficiency and control quality. They are suitable for mass-produced products, such as automotive parts, to replace professional measuring tools, such as smooth plug gauges, threaded plug gauges, and outside diameter calipers. After the automotive parts are processed, gauges are needed for measurement.

[0003] After searching, the utility model patent with announcement number CN220074488U discloses an automobile parts inspection fixture with a rotating mechanism, which solves the problem that the current automobile parts inspection fixture is inconvenient to clamp and fix parts of different shapes, affecting the measurement efficiency. The utility model comprises a base, the upper end of the base is rotatably connected to a processing plate, the upper end of the processing plate is provided with a threaded hole, the upper end of the processing plate is connected with a fixing component all around the upper end, and the fixing component comprises a support plate installed around the upper end of the processing plate. In the utility model, the pull plate drives the tooth plate to move, and the threaded rod moves downward to the inside of the threaded hole under the meshing transmission of the tooth plate and the gear, and the threaded connection between the threaded hole and the threaded rod fixes the support plate to the upper end of the processing plate. Under the action of the fixing component, the limit plate can be moved according to the shape of the required clamped part, which is convenient for clamping and fixing parts of different shapes, thereby improving work efficiency.

[0004] Although the above device can move the limit plate according to the different shapes of the parts when in use, fix the parts of different shapes and improve the work efficiency, the above device cannot replace the limit plate for clamping the parts when in use. When the clamping time is long, a certain deformation will occur. When deformation occurs, a gap will appear between the parts and the parts, and the parts cannot be stably clamped and fixed, which will have a certain impact in actual use. At the same time, it cannot protect the plastic parts when clamping them, and they are clamped by direct hard contact with the plastic parts, which will cause the plastic parts to be clamped in actual use. For this reason, we propose an automotive parts inner hole inspection fixture with a rotating mechanism. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 , an inner hole inspection fixture for automobile parts with a rotating mechanism, comprising a base 1, a U-shaped platform 2 is fixedly installed on the top of the base 1, two moving grooves 3 are evenly spaced on both sides of the top of the U-shaped platform 2, a servo motor 4 is arranged on the left side of the U-shaped platform 2, the output end of the servo motor 4 is sleeved with a bidirectional screw rod 5 through a coupling, a first connecting plate 6 and a second connecting plate 7 are respectively sleeved on both sides of the middle of the bidirectional screw rod 5, the middle of the first connecting plate 6 and the second connecting plate 7 are penetrated with a screw rod groove 8, two moving blocks 9 are fixedly installed at the bottom of the first connecting plate 6 and the second connecting plate 7, a driving motor 10 is arranged on one side of the first connecting plate 6 and the second connecting plate 7, a rotating rod 11 is sleeved on the output end of the two driving motors 10 through a coupling, a square plate 12 is arranged on one side of the two rotating rods 11, and an L-shaped positioning plate 13 is arranged on one side of the two square plates 12, a connecting frame 16 is fixedly installed on the back of the base 1, and supporting legs 19 are fixedly installed around the bottom of the base 1.

[0027] Furthermore, the first connecting plate 6 and the second connecting plate 7 are sleeved on both sides of the middle part of the bidirectional screw 5 through two screw grooves 8 and are both slidably connected to the U-shaped platform 2 in the moving groove 3 through the moving block 9.

[0028] Furthermore, the two L-shaped positioning plates 13 are both made of rubber material, which has the advantages that the bidirectional screw 5 is driven to rotate by the output end of the servo motor 4. When the bidirectional screw 5 rotates, it drives the first connecting plate 6 and the second connecting plate 7 through the two screw slots 8 and the corresponding moving blocks 9 to slide toward the two ends of the automobile part in the moving slot 3, and drives the two L-shaped positioning plates 13 to move synchronously during sliding. The distance between the two L-shaped positioning plates 13 is adjusted according to the automobile parts to clamp and fix them. At the same time, the material of the two L-shaped positioning plates 13 is set to rubber material, which can prevent unnecessary pinching caused by hard contact when the two L-shaped positioning plates 13 clamp and fix the automobile parts, thereby facilitating the operator to clamp and fix automobile parts of different diameters and effectively perform protective work.

[0029] Furthermore, the two L-shaped positioning plates 13 are fixedly connected to one side of the rotating rod 11 through the square plate 12, which has the advantage that the two rotating rods 11 are driven to rotate by the output ends of the two driving motors 10. When the two rotating rods 11 rotate, the two L-shaped positioning plates 13 and the automobile parts clamped therebetween are driven to rotate synchronously through the two square plates 12, thereby facilitating the operator to rotationally clamp and fix the automobile parts, thereby improving the diversified use and adaptability of the device.

[0030] Furthermore, two thread grooves 14 are equidistantly formed on one side of the square plate 12 and the L-shaped positioning plate 13. The thread grooves 14 are grouped in pairs and there are four groups in total. The inner cavity of each group of thread grooves 14 is threadedly connected with a bolt 15. Advantages: by rotating each bolt 15 counterclockwise in each group of corresponding and matching thread grooves 14 to remove it, the two square plates 12 and the two L-shaped positioning plates 13 can be released, and then the L-shaped positioning plates 13 can be separated and removed from the square plates 12, thereby facilitating the operator to replace the L-shaped positioning plates 13 that have been used for too long, and preventing the occurrence of unstable shaking caused by gaps when clamping and fixing automobile parts due to deformation caused by long-term use.

[0031] Furthermore, a lifting cylinder 17 is provided at the bottom of the lateral end of the connecting frame 16, and a detector 18 is fixedly installed at the bottom of the output end of the lifting cylinder 17. The advantage is that the detector 18 is driven by the output end of the lifting cylinder 17 to move up and down and adjust to a position close to the inner hole of the automobile part, so that the automobile part can be inspected by the detector 18, thereby facilitating the operator to perform inner hole inspection of automobile parts at different depths, providing effective convenience for the operator.

[0032] Furthermore, there are four supporting legs 19, which are equidistantly distributed in a matrix array around the bottom of the base 1, and the bottoms of the supporting legs 19 are all frosted. Advantages: by setting the number of supporting legs 19 to four and distributing them in a matrix array equidistantly around the bottom of the base 1, the four supporting legs 19 can be in a balanced state when supporting the base 1 to prevent tilting. At the same time, when the bottoms of the four supporting legs 19 are frosted, the friction resistance of the four supporting legs 19 in contact with the ground when supporting the base 1 can be increased to prevent unnecessary autonomous shaking, thereby improving the stability of the device during operation.

[0033] Working principle: When in use, firstly, the output end of the servo motor 4 is used to drive the bidirectional screw rod 5 to rotate. When the bidirectional screw rod 5 rotates, it drives the first connecting plate 6 and the second connecting plate 7 through the two screw rod grooves 8 and respectively passes through the corresponding moving blocks 9 to slide toward the two ends of the automobile parts in the moving groove 3. When sliding, it drives the two L-shaped positioning plates 13 to move synchronously. The distance between the two L-shaped positioning plates 13 is adjusted according to the automobile parts to clamp and fix them. At the same time, the material of the two L-shaped positioning plates 13 is set to rubber material. When the two L-shaped positioning plates 13 clamp and fix the automobile parts, unnecessary clamping injuries caused by hard contact can be prevented, so that it is convenient for operators to clamp and fix automobile parts of different diameters and can also effectively perform protective work. When the angle needs to be adjusted, the two rotating rods 11 can be driven to rotate by the output ends of the two driving motors 10. When the two rotating rods 11 rotate, they drive the two L-shaped positioning plates 13 and the automobile parts clamped therebetween to rotate synchronously through the two square plates 12. Thereby, it is convenient for the operator to perform rotational clamping and fixing of automobile parts, which can improve the diversified use and adaptability of the device. When the fixing is completed and the angle adjustment is completed, the output end of the lifting cylinder 17 can drive the detector 18 to move up and down and adjust to a position close to the inner hole of the automobile part, and the automobile part can be detected through the detector 18, so that it is convenient for the operator to perform inner hole detection of automobile parts at different depths, providing effective convenience for the operator; when it is necessary to replace the L-shaped positioning plate 13 that has been used for too long, each bolt 15 can be rotated counterclockwise in each group of corresponding and adapted thread grooves 14 to be taken out, so that the two square plates 12 and the two L-shaped positioning plates 13 are released from the fixation, and then the L-shaped positioning plate 13 can be separated and removed from the square plate 12, so that it is convenient for the operator to replace the L-shaped positioning plate 13 that has been used for too long, and prevent the occurrence of unstable shaking caused by gaps when clamping and fixing automobile parts due to deformation caused by long-term use.
