Description

Technical Field

[0001] The utility model relates to the field of parallelism gauges, in particular to a parallelism gauge for a sliding sleeve. Background Art

[0002] A parallelism gauge is used to measure and verify the parallelism of workpieces or assemblies. It ensures that the parallel relationship between two surfaces or axes meets the design requirements. Such a gauge usually has a high-precision measuring device for detecting errors that may occur during processing or assembly to ensure the normal function and fit of components.

[0003] It is difficult for traditional parallelism gauges for sliding sleeves to intuitively display the parallelism with data. Most of them can only be observed by the naked eye, and it is difficult to obtain accurate results. For this reason, a parallelism gauge for a sliding sleeve is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a parallelism gauge for a sliding sleeve, aiming to improve the problem that it is difficult for the gauge to quickly and accurately detect the parallelism of the sliding sleeve.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A parallelism gauge for a sliding sleeve, including a base, a sliding seat is slidably connected to the top of the base, a sliding sleeve is slidably connected to the outside of the sliding seat, a positioning surface is fixedly connected to the left side of the base, a spirit level is arranged on the top of the positioning surface, and a detection component is arranged inside the positioning surface. The component is used for detecting the parallelism of the notch of the sliding sleeve.

[0006] As a further description of the above technical scheme:

[0007] The detection component includes a convex block, the outside of the convex block is slidably connected inside the positioning surface, a second spring is sleeved outside the convex block, a second limiting plate is fixedly connected to the outside of the convex block, a sliding block is fixedly connected to the left end of the convex block, two support rods are fixedly connected to the bottom of the spirit level, the support rods are slidably connected inside the positioning surface, a first spring is sleeved outside the support rods, a first limiting plate is fixedly connected to the outside of the support rods, and an upper sliding block is fixedly connected to the bottom of the support rods. The bottom surface of the upper sliding block abuts against the top surface of the sliding block.

[0008] As a further description of the above technical scheme:

[0009] The upper part of the sliding seat is square.

[0010] As a further description of the above technical scheme:

[0011] A groove is formed at the top of the base, and the bottom of the sliding seat is slidably connected to the groove at the top of the base.

[0012] As a further description of the above technical solution:

[0013] The crescent-shaped part of the sliding sleeve contacts the convex block to the left.

[0014] As a further description of the above technical solution:

[0015] The left end of the second spring is fixedly connected to the right side of the lower sliding block, and the right end of the second spring is fixedly connected to the left side of the second limiting plate.

[0016] As a further description of the above technical solution:

[0017] The top end of the first spring is fixedly connected to the bottom end of the first limiting plate, and the bottom end of the first spring is fixedly connected to the inside of the positioning surface.

[0018] As a further description of the above technical solution:

[0019] The outer side of the second limiting plate is slidably connected to the inside of the positioning surface, and the outer side of the first limiting plate is slidably connected to the inside of the positioning surface.

[0020] The utility model has the following beneficial effects:

[0021] 1. In the utility model, through the mutual cooperation of structures such as the base and the sliding seat, the sliding sleeve, that is, the lower sliding sleeve, is clamped on the sliding seat, and the sliding seat drives the sliding sleeve to move towards the positioning surface. It only needs to judge whether the two protrusions at the crescent-shaped part of the sliding sleeve reach the positioning surface simultaneously, realizing the rapid detection of the parallelism of the lower sliding sleeve.

[0022] 2. In the utility model, under the mutual cooperation of structures such as the convex block, the lower sliding block and the upper sliding block, when the two protrusions at the crescent-shaped part of the lower sliding block contact the two convex blocks, the convex block will push the lower sliding block inward under pressure, and the lower sliding block will push the upper sliding block upward. Finally, the spirit level is supported below by the support rod, and the parallelism of the lower sliding sleeve is judged by reading the data of the spirit level, realizing the accurate judgment of the parallelism of the lower sliding sleeve.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Refer to Figure 1 - Figure 2 As shown in - [figure number not provided], an embodiment provided by the present invention: A parallelism gauge for a lower sliding sleeve, including a base 1, a slide base 4 is slidably connected to the top of the base 1, a sliding sleeve 5 is slidably connected to the outside of the slide base 4, a positioning surface 2 is fixedly connected to the left side of the base 1, a spirit level 3 is arranged on the top of the positioning surface 2, and a detection component is arranged inside the positioning surface 2. The component is used for detecting the parallelism of the notch of the sliding sleeve 5. The upper part of the slide base 4 is square, a groove is opened at the top of the base 1, and the bottom of the slide base 4 is slidably connected to the groove at the top of the base 1. The notch of the sliding sleeve 5 contacts the bump 6 to the left.

[0031] Specifically, a slide base 4 is slidably connected to the groove at the top of the base 1. The bottom of the slide base 4 slides in the groove of the base 1 and the upper part of the slide base 4 is square. The lower part of the sliding sleeve 5 is cylindrical and can be stuck on the outside of the slide base 4, ensuring that the sliding sleeve 5 can be stably fixed on the outside of the slide base 4. Slide the slide base 4 towards the positioning surface 2, and the protruding part of the notch of the sliding sleeve 5 first contacts the positioning surface 2. The parallelism of the notch of the sliding sleeve 5 is judged by the detection component inside the positioning surface 2.

[0032] Refer to Figure 3 - Figure 4, the detection component includes a bump 6. The outer side of the bump 6 is slidably connected to the inside of the positioning surface 2. A second spring 12 is sleeved on the outer side of the bump 6. A second limiting plate 13 is fixedly connected to the outer side of the bump 6. A lower slider 11 is fixedly connected to the left end of the bump 6. Two support rods 8 are fixedly connected to the bottom of the spirit level 3. The support rods 8 are slidably connected to the inside of the positioning surface 2. A first spring 9 is sleeved on the outer side of the support rods 8. A first limiting plate 10 is fixedly connected to the outer side of the support rods 8. An upper slider 7 is fixedly connected to the bottom of the support rods 8. The bottom surface of the upper slider 7 abuts against the top surface of the lower slider 11. The left end of the second spring 12 is fixedly connected to the right side of the lower slider 11. The right end of the second spring 12 is fixedly connected to the left side of the second limiting plate 13. The top end of the first spring 9 is fixedly connected to the bottom end of the first limiting plate 10. The bottom end of the first spring 9 is fixedly connected to the inside of the positioning surface 2. The outer side of the second limiting plate 13 is slidably connected to the inside of the positioning surface 2. The outer side of the first limiting plate 10 is slidably connected to the inside of the positioning surface 2.

[0033] Specifically, when the two protrusions at the moon-shaped notch respectively contact the two bumps 6, the bumps 6 are pushed towards the inside of the positioning surface 2. The second limiting plate 13 slides inwards following the bumps 6 and compresses the second spring 12. The lower slider 11 slides to the left and pushes the upper slider 7 upwards. The upper slider 7 pushes the support rods 8 directly upwards. When the upper slider 7 moves, the first limiting plate 10 will compress the first spring 9. Finally, the top of the support rods 8 will push the spirit level 3. By observing the data of the spirit level 3, the parallelism of the moon-shaped notch of the sliding sleeve 5 can be known. After removing the sliding seat 4, under the action of the first spring 9 and the second spring 12, each part returns to its original state.

[0034] Working principle: Through the sliding seat 4 on the top of the sliding base 1, the moon-shaped notch of the sliding sleeve 5 is driven to move towards the positioning surface 2. By judging the speed at which the two protrusions at the moon-shaped notch touch the surface of the positioning surface 2, the parallelism of the moon-shaped notch of the lower sliding sleeve can be accurately known. By arranging two bumps 6 on the right side of the positioning surface 2 and just at the positions that the sliding sleeve 5 can contact, through the contact of the sliding sleeve 5 with the bumps 6, the lower slider 11 is pushed and the upper slider 7 is pushed upwards. The upper slider 7 finally acts on both sides of the bottom of the spirit level 3 through the support rods 8. When observing the readings of the spirit level 3, it can be judged whether the parallelism of the moon-shaped notch of the sliding sleeve 5 is qualified.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
