[0001] The utility model relates to the technical field of parts detection, in particular to a three-seat parts inspection tool. Background Art

[0002] During the processing of parts, in order to ensure the processing accuracy of parts, it is necessary to inspect the dimensions of parts after processing. The dimension inspection includes the measurement of diameter, height, etc. During the inspection process, inspection fixtures are needed.

[0003] At present, in the process of cylindrical parts processing, it is necessary to detect the outer diameter of the parts. The photoelectric diameter gauge is a device that can automatically measure the outer diameter of the parts. When measuring the parts, the staff is required to hold the parts and pass them through the detection port of the photoelectric diameter gauge. However, some cylindrical parts are large and bulky, which is very inconvenient and laborious when detecting the outer diameter. In view of this, we propose a three-seat parts inspection fixture.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0029] This embodiment provides a technical solution:

[0030] See also Figure 1-Figure 5As shown, a three-seat parts inspection fixture includes a base 1, and ear plates 11 are fixed at two corners on the top rear side of the base 1, and a threaded rod 12 is rotatably installed between the two ear plates 11. The ear plate 11 located on the left is installed with a first motor 13 for driving the threaded rod 12 to rotate; a mounting frame 15 that can move horizontally is threadedly connected to the threaded rod 12, and a photoelectric diameter gauge 16 is installed on the inner top of the mounting frame 15; a plurality of fixing parts 2 for fixing parts are installed on the top front side of the base 1; the fixing part 2 includes a fixing seat 20, and a strip groove 201 is opened on the top of the fixing seat 20, and a double-headed screw 21 is rotatably installed in the strip groove 201, and a double-headed screw 21 is installed at the front end of the fixing seat 20 for driving the double-headed screw 21. A second motor 22 is provided for rotating the first lead screw 21; an electric cylinder 24 for driving the fixed seat 20 to rise and fall is installed below the fixed seat 20; connecting blocks 25 are threadedly connected to the threads at both ends of the double-headed lead screw 21, and an insert block 251 is installed on the top of the connecting block 25, and a fixing hole 252 is provided on the insert block 251; a connecting seat 26 is provided above the connecting block 25, and a slot 261 for plugging with the insert block 251 is provided at the bottom of the connecting seat 26, and a connecting bolt 27 is threadedly connected to the outer wall of the connecting seat 26, and the connecting bolt 27 passes through the fixing hole 252; clamping blocks 28 are installed on the two opposite end faces of the two connecting seats 26, and clamping grooves 281 for clamping parts are provided on the clamping blocks 28.

[0031] In this embodiment, guide rods 23 are fixed at the four corners of the bottom of the fixed seat 20. The guide rods 23 pass through the base 1 and are slidably connected to the base 1. The bottom end of the guide rods 23 is coaxially keyed to a limit block. The sliding connection between the guide rods 23 and the base 1 and the design of the limit block ensure the stability and safety of the fixed seat 20 during the lifting process. At the same time, the limit block can prevent the fixed seat 20 from being lifted excessively.

[0032] In this embodiment, the connection seat 26 and the clamping block 28 are an integrally formed structure, and both the connection seat 26 and the clamping block 28 are made of galvanized steel. The integrally formed structure enhances the strength and stability of the overall structure. The use of galvanized steel further improves corrosion resistance and prolongs service life.

[0033] In this embodiment, the overall shape of the clamping groove 281 is arc-shaped, and a rubber pad 282 is installed in the clamping groove 281. The arc-shaped design of the clamping groove 281 can better adapt to parts of different shapes and improve the flexibility and stability of clamping. The rubber pad 282 can reduce the wear of the parts during the clamping process and provide a certain buffer to protect the parts from damage.

[0034] In this embodiment, the electric cylinder 24 is located below the base 1, and the electric cylinder 24 is fixedly connected to the base 1 by bolts. By bolting, this installation method makes the drive of the electric cylinder more stable and improves the accuracy and reliability of the inspection fixture.

[0035] In this embodiment, the overall shape of the mounting frame 15 is L-shaped, and the mounting frame 15 is fixedly connected to the photoelectric caliper 16 by bolts. The mounting frame 15 is fixedly connected to the photoelectric caliper 16 by bolts, ensuring the stability and measurement accuracy of the caliper. The L-shaped mounting frame design also provides sufficient support area, further enhancing the stability of the structure.

[0036] In this embodiment, legs 10 are installed at the four corners of the bottom of the base 1, and the legs 10 are fixedly connected to the base 1 by bolts. This design enables the gauge to be stably placed on a plane, reducing measurement errors caused by uneven ground.

[0037] In this embodiment, a guide rail 14 is fixed at the top rear end of the base 1, and a slide groove slidably connected to the guide rail 14 is provided at the bottom end of the mounting frame 15. This design facilitates the horizontal and stable movement of the mounting frame 15, ensuring the stability and smoothness of the mounting frame 15.

[0038] In this embodiment, the number of the fixing seats 20 is 2-4, and the fixing seats 20 are made of galvanized steel. The preferred number of the fixing seats 20 is 3, and this design is conducive to fixing three parts at the same time, thereby facilitating the detection of three parts at the same time.

[0039] It should be added that the thread winding directions at both ends of the double-headed screw 21 in this embodiment are opposite, and the size of the connecting block 25 is adapted to the size of the strip groove 201. When the double-headed screw 21 rotates, the two connecting blocks 25 on both sides can move synchronously relative to each other along the strip groove 201. This design not only avoids the shaking of the connecting block 25 in the strip groove 201 due to the rotation of the double-headed screw 21, but also facilitates the synchronous relative movement of the clamping blocks 28 on both sides to clamp and fix the parts.

[0040] It is worth noting that the first motor 13 and the second motor 22 involved in this embodiment are existing conventional technologies and will not be described in detail here.

[0041] Before use, the user first places the part between two adjacent clamping blocks 28, then turns on the power of the second motor 22, the second motor 22 starts to work, the output shaft of the second motor 22 rotates to drive the double-headed screw 21 to rotate, the connecting blocks 25 on both sides move inward synchronously, and drive the connecting seat 26 and the clamping block 28 to approach the part, when the pads 282 on both sides clamp the part, the part is fixed, and then the user repeats the above steps and fixes multiple parts in sequence;

[0042] During specific use, the user first turns on the power of the first motor 13, and the first motor 13 starts to work. The output shaft of the first motor 13 rotates to drive the threaded rod 12 to rotate. As the threaded rod 12 rotates, the mounting frame 15 moves horizontally and drives the photoelectric caliper 16 to move horizontally. When the photoelectric caliper 16 moves to the top of the corresponding part, the power of the first motor 13 is stopped. Then the user turns on the power of the electric cylinder 24, and the piston rod of the electric cylinder 24 drives the fixing seat 20 to move upward. When the top of the part passes through the detection port of the photoelectric caliper 16, the user stops the power of the electric cylinder 24. Finally, the user turns on the power of the photoelectric caliper 16 to detect the part.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
