Description
Technical Field
[0001] This utility model relates to the technical field of go / no-go gauge related equipment, specifically a go / no-go gauge testing and fixing device. Background Technology
[0002] A go / no-go gauge is a precision measuring tool used to check whether the dimensions of a workpiece are within the specified tolerance range. It consists of two parts: a go gauge and a no-go gauge, and can quickly and efficiently perform limit dimension checks on workpieces.
[0003] The size of the go gauge is equal to the minimum limit size of the workpiece. It is used to check whether the workpiece can pass smoothly. If it can pass, it means that the workpiece size is greater than or equal to the minimum limit size requirement. The size of the no-go gauge is equal to the maximum limit size of the workpiece. It is used to determine whether the workpiece exceeds the maximum size limit. If it cannot pass, it means that the workpiece size meets the requirement of not exceeding the maximum limit size.
[0004] The go / no-go gauge needs to be rotated into the threaded hole of the workpiece for inspection. However, the go / no-go gauge is not fixed during use, so it needs to be held to enter the workpiece during inspection, which makes the inspection process cumbersome.
[0005] Therefore, a fixing device for checking go and no-go gauges is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

A placement slot is provided in the middle of the base; the placement slot is located below the go / no-go gauge body; by setting the insertion rod to be hexagonal, it can adapt to the shape of the go / no-go gauge body when installing it, thereby increasing the thrust when rotating the go / no-go gauge body. At the same time, the magnetic force generated by the magnetic rod can be used to attract and fix the go / no-go gauge body during installation, which can speed up the installation of the go / no-go gauge body. This speeds up the installation of the go / no-go gauge body. In addition, fixing the go / no-go gauge body can increase the convenience when using the go / no-go gauge body to inspect the workpiece, thereby increasing the speed of inspection.
[0008] Preferably, the inner wall of the insertion rod is fixed with multiple fixing plates; the surface of the go / no-go gauge body is provided with multiple slots; the fixing plates and slots are correspondingly arranged and slidably engaged; by adding fixing plates and slots, the fixing plates can be restricted by the slots when installing the go / no-go gauge body, thereby increasing the contact area through the fixing plates and slots during rotation, thus increasing friction, reducing slippage during rotation, and thereby accelerating the rotation of the go / no-go gauge body.
[0009] Preferably, a round rod is fixed to the end of the go / no-go gauge body; a round groove is formed at the end of the magnetic rod; the round rod and the round groove are correspondingly arranged and slidably fitted; by adding the round rod and the round groove, when fixing the go / no-go gauge body, the round rod can penetrate into the magnetic rod, thereby increasing the adsorption area of the go / no-go gauge body and thus increasing the stability during fixing.
[0010] Preferably, the inner wall of the insertion rod is provided with multiple square grooves; a clamping plate is rotatably connected to the inner wall of the square groove; the clamping plate and the square groove are connected by a coil spring; by adding the clamping plate, the lateral clamping of the go / no-go gauge body can be increased when fixing the go / no-go gauge body, thereby making the installation of the go / no-go gauge body more stable and reducing the shaking of the go / no-go gauge body.
[0011] Preferably, a plurality of spring telescopic rods are fixedly connected to the inner wall of the placement groove; a push plate is fixedly connected to the end of each spring telescopic rod; by adding spring telescopic rods, the push plate can be pushed to fit tightly against the workpiece through the compression of the spring telescopic rods, thereby reducing the movement of the workpiece after it is placed.
[0012] Preferably, a rubber pad is fixed to the end of the go / no-go gauge body; the rubber pad is through the round rod; by adding the rubber pad, the impact between the go / no-go gauge body and the magnetic rod can be reduced during the installation of the go / no-go gauge body, thereby protecting the go / no-go gauge body and increasing its service life.
[0013] The advantages of this utility model are:
[0014] 1. The go / no-go gauge inspection and fixing device of this utility model, by setting the insertion rod to be hexagonal, can adapt to the shape of the go / no-go gauge body when installing it, thereby increasing the thrust when rotating the go / no-go gauge body. At the same time, the magnetic force generated by the magnetic rod can be used to attract and fix the go / no-go gauge body during installation, which can speed up the installation of the go / no-go gauge body. In addition, fixing the go / no-go gauge body can increase the convenience of using the go / no-go gauge body to inspect the workpiece, thereby increasing the speed of inspection.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a go / no-go gauge testing and fixing device includes a base 1, a support frame 11 fixedly connected to the top of the base 1; a pair of linear motors 12 fixedly connected to the inner wall of the support frame 11; a sliding plate 13 slidably connected to the surface of the linear motors 12; a servo motor 14 fixedly connected to the middle of the sliding plate 13; a magnetic rod 15 fixedly connected to the output end of the servo motor 14; the magnetic rod 15 is through-mounted and rotatably connected to the sliding plate 13; an insertion rod 16 is fixedly connected to the end of the magnetic rod 15; the insertion rod 16 is hexagonal; a go / no-go gauge body 17 is slidably fitted inside the insertion rod 16; a placement groove 18 is opened in the middle of the base 1; the placement groove 18 is located below the go / no-go gauge body 17; during operation, the go / no-go gauge body 17 is first inserted into the insertion rod 16, and then the magnetic force generated by the magnetic rod 15 will attract and fix the go / no-go gauge body 17. Then, the workpiece is placed into the placement groove 18. After the workpiece is placed, the linear motor 12 is started to move the sliding plate 13. The gauge body 17 moves downwards towards the workpiece. Once it contacts the workpiece, the servo motor 14 is activated, causing the servo motor 14 to drive the magnetic rod 15 to rotate. When the magnetic rod 15 rotates, it drives the insertion rod 16 to rotate. At this time, the insertion rod 16 pushes the internal gauge body 17 due to its edge, thereby causing the gauge body 17 to rotate and enter the workpiece for inspection. By setting the insertion rod 16 to be hexagonal, it can adapt to the shape of the gauge body 17 during installation, thereby increasing the thrust when the gauge body 17 rotates. At the same time, the magnetic force generated by the magnetic rod 15 can attract and fix the gauge body 17 during installation, which can speed up the installation of the gauge body 17. This also speeds up the installation of the gauge body 17 and makes it easier to use the gauge body 17 for workpiece inspection, thus increasing the inspection speed.
[0026] like Figures 1 to 4 As shown, multiple fixing plates 2 are fixedly connected to the inner wall of the insertion rod 16; multiple slots 21 are opened on the surface of the go / no-go gauge body 17; the fixing plates 2 and slots 21 are correspondingly arranged and slidably engaged; during operation, when installing the go / no-go gauge body 17, the slots 21 are first aligned with the fixing plates 2 and inserted, thereby increasing the contact area of the go / no-go gauge body 17 during installation through the fixing plates 2 and slots 21. When the servo motor 14 is used to rotate, the fixing plates 2 will apply a pushing force to the go / no-go gauge body 17 when the insertion rod 16 rotates, thereby increasing the pushing force when rotating into the workpiece, thus increasing stability during rotation; by adding fixing plates 2 and slots 21, the fixing plates 2 can be restricted by the slots 21 during installation of the go / no-go gauge body 17, thereby increasing the contact area of the fixing plates 2 and slots 21 during rotation, thereby increasing friction, reducing slippage during rotation, and thus accelerating the rotation of the go / no-go gauge body 17.
[0027] like Figures 3 to 4 As shown, a round rod 3 is fixedly connected to the end of the go / no-go gauge body 17; a round groove 31 is opened at the end of the magnetic rod 15; the round rod 3 and the round groove 31 are correspondingly arranged and slidably engaged; during operation, when the go / no-go gauge body 17 is installed, after the end of the go / no-go gauge body 17 enters the insertion rod 16, it will move closer to the magnetic rod 15 due to the magnetic force of the magnetic rod 15. At this time, the round rod 3 will enter the round groove 31, thereby increasing the contact with the magnetic rod 15 when fixing the go / no-go gauge body 17; by adding the round rod 3 and the round groove 31, when fixing the go / no-go gauge body 17, the round rod 3 can penetrate into the magnetic rod 15, thereby increasing the adsorption area of the go / no-go gauge body 17 and increasing the stability during fixing.
[0028] like Figure 3 As shown, the inner wall of the insertion rod 16 has multiple square grooves 4; a clamping plate 41 is rotatably connected to the inner wall of the square groove 4; the clamping plate 41 and the square groove 4 are connected by a coil spring; during operation, when installing the go / no-go gauge body 17, it will first contact the clamping plate 41 when it enters the insertion rod 16. As the go / no-go gauge body 17 continues to enter, it will push the clamping plate 41 into the square groove 4. When the go / no-go gauge body 17 is completely inside the insertion rod 16, the clamping plate 41 can be rotated by the force of the coil spring, thus tightly adhering to the go / no-go gauge body 17, thereby increasing the clamping of the go / no-go gauge body 17; by adding the clamping plate 41, the lateral clamping of the go / no-go gauge body 17 can be increased when fixing the go / no-go gauge body 17, thereby making the installation of the go / no-go gauge body 17 more stable and reducing the shaking of the go / no-go gauge body 17.
[0029] like Figure 5 As shown, multiple spring telescopic rods 5 are fixedly connected to the inner wall of the placement groove 18; a push plate 51 is fixedly connected to the end of each spring telescopic rod 5; during operation, when the workpiece is installed, it will first contact the push plate 51, at which time the push plate 51 will move into the placement groove 18, and at the same time the push plate 51 will squeeze the spring telescopic rods 5, at which time the spring telescopic rods 5 will be compressed. After the workpiece is placed, the spring telescopic rods 5 will apply a pushing force to the push plate 51 to make it stick tightly to the side wall of the workpiece, thereby increasing the fixation after the workpiece is placed; by adding spring telescopic rods 5, the compression of the spring telescopic rods 5 can push the push plate 51 to stick tightly to the workpiece, thereby reducing the movement of the workpiece after it is placed.
[0030] like Figure 4As shown, a rubber pad 6 is fixed to the end of the go / no-go gauge body 17; the rubber pad 6 is through-hole disposed on the round rod 3; during operation, after the go / no-go gauge body 17 is inserted into the insertion rod 16, when the go / no-go gauge body 17 accelerates due to the magnetic force of the magnetic rod 15, the rubber pad 6 will be in the middle when the go / no-go gauge body 17 and the magnetic rod 15 come into contact, thereby reducing the impact force when the go / no-go gauge body 17 moves towards the magnetic rod 15 when fixing the go / no-go gauge body 17; by adding the rubber pad 6, the impact between the go / no-go gauge body 17 and the magnetic rod 15 can be reduced when installing the go / no-go gauge body 17, thereby protecting the go / no-go gauge body 17 and increasing its service life.
[0031] Working principle: First, the go / no-go gauge body 17 is inserted into the insertion rod 16. Then, the magnetic force generated by the magnetic rod 15 attracts and fixes the go / no-go gauge body 17. Next, the workpiece is placed into the placement slot 18. After the workpiece is placed, the linear motor 12 is started, causing the slide plate 13 to move downwards and towards the workpiece. When the go / no-go gauge body 17 contacts the workpiece, the servo motor 14 is started, causing the servo motor 14 to drive the magnetic rod 15 to rotate. When the magnetic rod 15 rotates, it drives the insertion rod 16 to rotate. At this time, the insertion rod 16 pushes the go / no-go gauge body 17 inside due to its edge, thereby driving the go / no-go gauge body 17 to rotate. This allows the go / no-go gauge body 17 to enter the workpiece for inspection. During installation, the slot 21 is aligned with the fixing plate 2 and inserted. This increases the contact area between the fixing plate 2 and the slot 21. When the servo motor 14 rotates, the fixing plate 2 applies a pushing force to the go / no-go gauge body 17 as the insertion rod 16 rotates, increasing the pushing force when it enters the workpiece and thus increasing stability during rotation. During installation, once the end of the go / no-go gauge body 17 enters the insertion rod 16, the magnetic force of the magnetic rod 15... As the rod approaches the magnetic rod 15, the round rod 3 enters the round groove 31, thus increasing the contact with the magnetic rod 15 when fixing the go / no-go gauge body 17. When installing the go / no-go gauge body 17, it first contacts the clamping plate 41 upon entering the insert rod 16. As the go / no-go gauge body 17 continues to enter, it pushes the clamping plate 41 into the square groove 4. Once the go / no-go gauge body 17 is fully inside the insert rod 16, the clamping plate 41 can be rotated by the force of the coil spring, thus tightly adhering to the go / no-go gauge body 17 and increasing its clamping force. When installing the workpiece, it first contacts the push plate 51. The push plate 51 moves into the placement slot 18, and at the same time, the push plate 51 squeezes the spring telescopic rod 5. At this time, the spring telescopic rod 5 is compressed. After the workpiece is placed, the spring telescopic rod 5 applies a pushing force to the push plate 51 to make it fit tightly against the side wall of the workpiece, thereby increasing the fixation after the workpiece is placed. After the go / no-go gauge body 17 is inserted into the insertion rod 16, when the go / no-go gauge body 17 moves faster due to the magnetic force of the magnetic rod 15, the rubber pad 6 will be in the middle when the go / no-go gauge body 17 and the magnetic rod 15 come into contact. This reduces the impact force when the go / no-go gauge body 17 moves towards the magnetic rod 15 when fixing the go / no-go gauge body 17.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
