The bottom of the front end of the fork head is concave upward in an arc shape, and two through holes 6 are oppositely opened at the ends of the two fork feet. In order to detect whether the core groove, long hole, arc concave position, through hole and the radian angle formed by the two fork feet are qualified, the present utility model innovatively designs a comprehensive inspection tool for contour inspection.

[0026] The comprehensive inspection tool for contour inspection includes an inspection table 7. A positioning seat 8 and a side-end inspection seat 9 are oppositely arranged on the inspection table. A support seat 10 for supporting under the middle part of the fork is arranged between the positioning seat and the side-end inspection seat. A vertical inspection seat 11 is arranged at the side end of the support seat. A vertical inspection hole 13 for the vertical inspection rod 12 to be inserted upward from the bottom is vertically opened on the vertical inspection seat. The vertical inspection hole penetrates the inspection table downward. Horizontal inspection holes 15 for the concentric inspection rod 14 to be inserted in opposite directions are coaxially opened on both the positioning seat and the side-end inspection seat. A detection core rod 16 for detecting the size of the core groove of the fork and whether it is in position is also horizontally slidably connected in the positioning seat. A quick clamp 17 is arranged inside the positioning seat to clamp one side of the fork on the positioning seat. The model of the quick clamp is selected as CH-101-A quick clamp.

[0027] In the embodiment of the present utility model, a support block 18 protrudes vertically upward on the support seat. An arc convex surface 19 that coincides with the arc concave part at the bottom of the fork is arranged at the top of the support block. The support seat, vertical inspection seat, positioning seat and side-end inspection seat are all fixed on the inspection table.

[0028] In the embodiment of the present utility model, a length detection position 21 for inserting and detecting a length detection rod 20 is provided between the side-end detection seat and the end of the fork away from the quick clamp. The cross-section of the length detection rod is rectangular, and the lower part of one of the stepped holes is rectangular for inserting and placing the length detection rod.

[0029] In the embodiment of the present utility model, a placement seat 22 for recycling and placing the above-mentioned detection rods is fixedly provided on the detection table. A stepped hole 23 for vertically inserting the detection rod is opened on the placement seat, and the stepped holes vertically penetrate the detection table.

[0030] In the embodiment of the present utility model, a clamping block 24 is fixedly connected to the lower end of the clamping handle of the quick clamp. A U-shaped relief groove 25 is opened on the clamping block to make way for the concentric detection rod.

[0031] In the embodiment of the present utility model, the cross-sections of the vertical detection rod, the concentric detection rod and the detection core rod are all circular, and sliding rods 26 respectively slidably matched with the vertical detection seat, the side-end detection seat and the positioning seat are fixedly connected to their ends. Handles 27 are fixedly connected to the outer ends of the sliding rods.

[0032] In the embodiment of the present utility model, strip-shaped grooves 28 are opened on the sliding rods. Anti-detachment grooves 29 are recessed at the bottoms of both ends of the strip-shaped grooves. Anti-detachment members 30 are fixedly connected to the outer sides of the positioning seat and the side-end detection seat. Screws 31 are screwed on the side parts of the anti-detachment members and radially extend into the strip-shaped grooves and the anti-detachment grooves to prevent detachment.

[0033] In the embodiment of the present utility model, the detection table is supported by support feet 32 below, and lifting handles 33 are symmetrically arranged at both side ends of the detection table.

[0034] The working principle of the embodiment of the present utility model: First, place the fork to be detected on the support block, and the rear end of the fork head is supported by the vertical detection seat. By observing whether the arc-shaped concave position and the arc-shaped convex surface match, that is, the contour and size of the detector. Then insert the detection core rod to detect whether it is aligned with the core groove and the size of the core groove. Then, use the quick clamp to press one of the fork feet against the inner end of the positioning seat for clamping. Then insert the concentric detection rod in opposite directions to detect the size of the two through holes and whether they are concentric. Then insert the length detection rod into the length detection position to detect whether the length of the fork is accurate. Finally, insert the vertical detection rod from bottom to top to detect whether the size and position of the long hole are aligned. Most of the above is through observing the sliding fit degree between the detection rod and the hole position. If interference or jamming occurs and it cannot be inserted, it means that the hole position size of the part is unqualified. After the detection is completed, the redundant detection rods can be inserted into the placement seat for collection, and the detection work of the next fork can be carried out.

[0035] The utility model is not limited to the above-mentioned optimal implementation mode, and anyone can obtain various other forms of comprehensive inspection tools for the profile inspection of the turbocharger fork under the inspiration of the utility model. All equivalent changes and modifications made according to the scope of the patent application of the utility model shall fall within the scope covered by the utility model.
