Description

Technical Field

[0001] The utility model relates to the technical field of detecting the outer diameter of disc-shaped parts, in particular to a fixture for efficiently detecting the outer diameter of disc-shaped parts. Background Art

[0002] The structure of the disc-shaped parts produced in a certain workshop is as Figures 1 to 2 shown. The outer cylindrical surface 2 of the disc-shaped part 1 is inclined upward to the right, that is, the angle between the axis of the outer cylindrical surface 2 and the horizontal plane is A, and A is 60° - 75°. The top and bottom surfaces of the disc-shaped part 1 are both circular.

[0003] When a batch of disc-shaped parts are produced in the workshop, the process requires detecting the outer diameter of each disc-shaped part 1 (the purpose of detection is that due to processing technology reasons, the outer diameter of some disc-shaped parts 1 exceeds the design range), removing the disc-shaped parts with unqualified outer diameter, and putting the disc-shaped parts with qualified outer diameter into the finished product basket.

[0004] Currently, vernier calipers are used in the workshop to detect the outer diameter of each disc-shaped part 1. The specific detection method is as follows:

[0005] S1. A worker takes out a disc-shaped part 1 to be detected from the material basket;

[0006] S2. The two jaws of the vernier caliper are respectively abutted against the left and right outer contours of the disc-shaped part 1, and then a value is read on the vernier caliper. This value is the outer diameter of the disc-shaped part 1. If the outer diameter is within the design range, it is determined that the disc-shaped part 1 is a qualified product, and the worker puts the qualified product into the finished product basket; if the outer diameter is not within the design range, it is determined that the disc-shaped part 1 is an unqualified product, and the worker removes the unqualified product into the waste basket, thus finally realizing the detection of the outer diameter of the first disc-shaped part 1;

[0007] S3. The worker repeats the operations in steps S1 - S2 in this way, and can continuously detect the outer diameters of multiple disc-shaped parts 1.

[0008] However, although the detection method in the workshop can detect the outer diameter of the disc-shaped part 1, there are still the following technical defects in terms of technology:

[0009] It is necessary for the worker to first abut the two jaws of the vernier caliper against the left and right outer contours of the disc-shaped part 1 respectively, then manually read the value on the vernier caliper, and then judge whether this value is within the design range to determine whether the outer diameter of the detected disc-shaped part 1 is qualified; and the whole operation is completed manually, and there are many operation procedures, which not only increases the working intensity of the worker, but also takes a long time to detect all the disc-shaped parts 1 in a batch, thereby reducing the detection efficiency.

[0010] Therefore, there is an urgent need for a checking fixture that can greatly reduce the working intensity of workers and greatly improve the detection efficiency. Summary of the Utility Model

[0011] The purpose of the present utility model is to overcome the shortcomings of the prior art and provide a checking fixture for efficiently detecting the outer diameter of disc-shaped parts, which can greatly reduce the working intensity of workers and greatly improve the detection efficiency.

[0012] The purpose of the present utility model is achieved through the following technical solutions: A checking fixture for efficiently detecting the outer diameter of disc-shaped parts, which includes a longitudinal strip-shaped seat. An inclined surface that slopes downward to the left is provided on the top surface of the strip-shaped seat. A baffle is fixedly provided on the left end surface of the strip-shaped seat. The angle between the vertical surface of the baffle and the inclined surface is A. A connecting seat is fixedly provided on the right end surface of the strip-shaped seat. A vertical seat is fixedly provided on the right end surface of the connecting seat. A dial indicator is fixedly provided on the right end surface of the vertical seat. The detection rod of the dial indicator penetrates through the vertical seat to the left and extends above the inclined surface.

[0013] An installation plate is fixedly provided on the rear end surface of the strip-shaped seat. A pushing cylinder is fixedly provided on the rear end surface of the installation plate. The piston rod of the pushing cylinder penetrates through the installation plate forward, and a pushing plate is connected to the extending end. The bottom surface of the pushing plate is in contact with the inclined surface.

[0014] A through hole is provided in the vertical seat. A locking screw is threadedly connected to the top of the vertical seat. The fixing rod of the dial indicator passes through the through hole. Under the threaded connection force between the locking screw and the vertical seat, the end of the locking screw presses against the fixing rod of the dial indicator to fix the fixing rod, and thus fix the dial indicator.

[0015] The baffle is detachably fixed to the left end surface of the strip-shaped seat by screws.

[0016] The vertical seat and the connecting seat are integrally formed and perpendicular to each other.

[0017] The present utility model has the following advantages: greatly reducing the working intensity of workers and greatly improving the detection efficiency. Description of the Drawings

Specific implementation mode

[0028] The following further describes the present utility model in conjunction with the attached drawings. The protection scope of the present utility model is not limited to the following:

[0029] As Figures 3 to 6 shown, a fixture for efficiently detecting the outer diameter of a disk-shaped part includes a longitudinally arranged bar-shaped seat 3. An inclined surface 4 that slopes downward to the left is provided on the top surface of the bar-shaped seat 3. A baffle 5 is fixedly provided on the left end surface of the bar-shaped seat 3. The baffle 5 is detachably fixed to the left end surface of the bar-shaped seat 3 by screws. The angle between the vertical surface of the baffle 5 and the inclined surface 4 is A. A connecting seat 6 is fixedly provided on the right end surface of the bar-shaped seat 3. A vertical seat 7 is fixedly provided on the right end surface of the connecting seat 6. A micrometer 8 is fixedly provided on the right end surface of the vertical seat 7. The detection rod 9 of the micrometer 8 penetrates the vertical seat 7 to the left and extends above the inclined surface 4; the vertical seat 7 and the connecting seat 6 are integrally formed, and the vertical seat 7 and the connecting seat 6 are perpendicular to each other.

[0030] A mounting plate 10 is fixedly provided on the rear end surface of the bar-shaped seat 3. A pushing cylinder 11 is fixedly provided on the rear end surface of the mounting plate 10. The piston rod of the pushing cylinder 11 penetrates the mounting plate 10 forward, and a pushing plate 12 is connected to the extending end. The bottom surface of the pushing plate 12 is in contact with the inclined surface 4.

[0031] A through hole 13 is provided in the vertical seat 7. A locking screw 14 is threadedly connected to the top of the vertical seat 7. The fixing rod of the micrometer 8 is inserted into the through hole 13. Under the threaded connection force between the locking screw 14 and the vertical seat 7, the end of the locking screw 14 presses against the fixing rod of the micrometer 8 to fix the fixing rod, and thus the micrometer 8 is fixed.

[0032] The working process of the present utility model is as follows:

[0033] S1. A worker takes out a disk-shaped part 1 to be detected, such as Figures 1 to 2 shown, from the material basket;

[0034] S2. Place the bottom surface of the disk-shaped part 1 on the inclined surface 4 of the bar-shaped seat 3. Under the self-weight of the disk-shaped part 1, the left contour of the disk-shaped part 1 abuts against the vertical surface of the baffle 5, thereby realizing the positioning of the disk-shaped part 1. Since the angle between the vertical surface of the baffle 5 and the inclined surface 4 is A, and the angle between the axis of the outer cylindrical surface 2 of the disk-shaped part 1 and the horizontal plane is also A, therefore, the axis of the disk-shaped part 1 is in a vertical state;

[0035] S3. Control the piston rod of the pushing cylinder 11 to extend forward. The piston rod drives the push plate 12 to move forward. The push plate 12 pushes the disk-shaped part 1 forward along the inclined surface 4. When the disk-shaped part 1 passes forward through the detection rod 9 of the dial indicator 8, as Figures 7 to 9 shown, if the pointer on the dial indicator 8 jumps, it means that the outer diameter of the detected disk-shaped part 1 is not within the design range, and this disk-shaped part 1 is a defective product. The worker removes the defective product into the waste basket;

[0036] If the pointer on the detection rod 9 does not jump, it means that the outer diameter of the detected disk-shaped part 1 is within the design range, and this disk-shaped part 1 is a qualified product. The worker puts the qualified product into the finished product basket, thereby finally realizing the detection of the outer diameter of the first disk-shaped part 1;

[0037] Among them, it can be seen from steps S2 to S3 that the worker only needs to first place the disk-shaped part 1 on the inclined surface 4 of the bar-shaped seat 3 to quickly position the disk-shaped part 1; then control the piston rod of the pushing cylinder 11 to extend forward, and push the disk-shaped part 1 on the inclined surface 4 to the detection station of the detection rod 9 of the dial indicator 8 through the push plate 12; finally, by checking whether there is a reading on the dial indicator 8, it can be quickly judged whether the detected disk-shaped part 1 is a qualified product or a defective product.

[0038] It can be seen from this that compared with the worker using a vernier caliper for detection, this inspection tool does not require manual operation of the vernier caliper, thus greatly reducing the working intensity of the worker. At the same time, it also simplifies the detection process, thereby realizing the detection of a batch of disk-shaped parts 1 in a short time, and further greatly improving the detection efficiency.

[0039] S4. The worker repeats the operations in steps S1 to S3 in this way, and can continuously detect the outer diameters of multiple disk-shaped parts 1.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
