Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically a fixture and its horizontal double-end face grinding machine. Background Technology

[0002] In existing technologies, horizontal double-end face grinders are widely used for precision machining of thin sheet-like workpieces. However, the traditional bolt-fastening structure is commonly used for fixture installation. This method has several drawbacks in practical applications: First, each fixture change requires the disassembly and reassembly of multiple fixing screws, which is cumbersome and time-consuming, significantly reducing the production cycle and resulting in low overall machining efficiency. Second, because the screw connection requires frequent disassembly and reassembly, long-term use can easily cause wear between the fixture and the mounting surface, thus affecting the repeatability of the fixture and ultimately leading to unstable workpiece machining quality. In addition, if the screws become loose or the preload is uneven during installation, it may cause fixture displacement or vibration, which not only affects machining accuracy but also poses safety hazards such as workpiece scrapping or even equipment damage.

[0003] Although some quick-change fixture designs have emerged in the existing technology to improve changeover efficiency, most of them rely on hydraulic or pneumatic drive mechanisms, resulting in complex system structures, high manufacturing costs, and difficult maintenance, making them unsuitable for promotion and application in small and medium-sized enterprises. Therefore, a fixture tooling and its horizontal double-end face grinder are proposed. Utility Model Content

[0015] 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 protection scope of the present utility model.

[0016] Please see Figure 1-4 In this embodiment of the utility model, a fixture includes: Guide plate 1, which has a locking groove 11; Connecting block 2 is connected to guide plate 1, and its end face away from guide plate 1 is connected to grinding machine. The connecting block 2 has a positioning hole that communicates with locking groove 11. The pin 3 is located inside the positioning hole. The outer circumference of the pin 3 is provided with an adjusting nut 4, and a pad 5 is sleeved on the outer circumference of the pin 3 at the position between the adjusting nut 4 and the guide plate 1. The end of the pin 3 that passes through the positioning hole is equipped with a telescopic member 6, the end of which can extend or retract from the inside of the pin 3.

[0017] Specifically, the guide plate 1 has a rectangular structure with a smooth contact surface with the product to be processed to reduce friction. Two locking grooves 11 are provided on the guide plate 1, which restrict the horizontal movement range of the guide plate 1. The connecting block 2 is connected to the guide plate 1 by bolts, and its other end is connected to the grinding machine. The outer circumference of the pin 3 has an external thread that mates with the internal thread of the adjusting nut 4. The adjusting nut 4 can be rotated to adjust its axial position on the pin 3, thus adapting to guide plates 1 of different thicknesses. The outer diameter of the pin 3 matches the inner diameter of the positioning hole to ensure smooth insertion. The pin 3 has a telescopic component 6 inside: when the telescopic component 6 retracts, the pin 3 can smoothly pass through the positioning hole; when the telescopic component 6 extends, it can abut against one end of the positioning hole, thus adjusting the pin 3. Axial limiting is performed, and then the adjusting nut 4 is rotated to push the pad 5 to gradually press one side of the guide plate 1. The compression action achieves clamping and reliable fixation of the guide plate 1 on both sides. When the guide plate 1 needs to be replaced, simply press the telescopic component 6 to retract it into the pin 3, release the limiting with the groove 21, and then pull out the pin 3 as a whole to complete the disassembly. After installing the new guide plate, by rotating the adjusting nut 4, the position of the guide plate 1 on the pin 3 is adjusted according to the actual thickness of the guide plate 1 to ensure that the clamping force is moderate and the fixation is reliable. This enables quick replacement and precise adaptation of guide plates 1 of different thicknesses. Through the coordinated cooperation of the adjusting nut 4, the pin 3 and the telescopic component 6, the structure realizes the quick installation, positioning and clamping of guide plates 1 of different thicknesses, improving the flexibility and stability of clamping.

[0018] Please see Figure 2In one embodiment, preferably, the connecting block 2 has a horizontal through groove 21, which is connected to the positioning hole. The end of the pin 3 passes through the positioning hole and enters the interior of the groove 21. Furthermore, the groove 21 facilitates the operator's hand to contact the telescopic member 6 and change the state of the telescopic member 6 by pressing it.

[0019] Please see Figure 3 In one embodiment, preferably, one end of the pin 3 is provided with a cavity 31 for accommodating the telescopic member 6, and the other end of the pin 3 is equipped with an operating handle 32. Furthermore, when the telescopic member 6 retracts, the telescopic member 6 enters the interior of the cavity 31, while in the initial state, the end of the telescopic member 6 protrudes out of the cavity 31.

[0020] Please see Figure 3 In one embodiment, preferably, the telescopic member 6 includes a first spring 601 installed inside the cavity 31. A locking block 602 is installed at the end of the first spring 601. The outer diameter of the locking block 602 is adapted to the inner diameter of the cavity 31. Furthermore, when the first spring 601 is in the initial state, the end of the locking block 602 away from the first spring 601 protrudes outside the cavity 31. When the first spring 601 is in the compressed state and the locking block 602 is fully inserted into the cavity 31, the pin 3 can enter through the positioning hole.

[0021] Please see Figure 1 In one embodiment, preferably, the adjusting nut 4 has a T-shaped structure, and the adjusting nut 4 is connected to the pin 3 by a thread, with the end of the adjusting nut 4 inserted into the inside of the pad 5.

[0022] Please see Figure 1 In one embodiment, preferably, the inner diameter of the pad 5 is larger than the outer diameter of one end of the adjusting nut 4, and the inner diameter of the pad 5 is smaller than the outer diameter of the other end of the adjusting nut 4. Furthermore, the end of the adjusting nut 4 smaller than the inner diameter of the pad 5 is the small end, and the end of the adjusting nut 4 larger than the inner diameter of the pad 5 is the large end. The small end is easy to insert into the inside of the pad 5, while the large end achieves a limiting fit with the pad 5 and provides support for the end of the second spring 7.

[0023] Please see Figure 1In one embodiment, preferably, a second spring 7 is sleeved on the outer circumferential surface of the adjusting nut 4. The two ends of the second spring 7 are respectively connected to the pad 5 and the adjusting nut 4. Furthermore, when the second spring 7 releases its elastic force to both sides, the position of the pad 5 is constrained by the guide plate 1 and remains fixed. At the same time, the adjusting nut 4 and the pin 3 are pushed outward under the elastic force of the second spring 7. As the pin 3 moves, the telescopic member 6 on it gradually moves towards the inner wall of the groove 21 and finally abuts against the inner wall of the groove 21, realizing positioning and limiting, and ensuring that the entire structure is stable and reliable.

[0024] Please see Figure 4 A horizontal double-end face grinder includes the above-mentioned fixtures, with two clamping fixtures located above and below the product to be processed, respectively.

[0025] The working principle and usage process of this utility model are as follows: Connect the connecting block 2 to the base fixed on the grinding machine worktable, ensuring that the positioning hole is aligned with the machine tool coordinate system. Then, pass the end of the pin 3 through the locking groove 11 and through the positioning hole into the groove 21 of the connecting block 2. During the insertion process, the second spring 7 is continuously compressed. Subsequently, the pad 5 abuts against the guide plate 1. Then, the pin 3 is released. Under the action of the return spring force of the second spring 7, the pin 3 and the adjusting nut 4 are pushed and moved towards the side closer to the operating handle 32, so that the telescopic part 6 on the pin 3 extends out and abuts tightly against the inner wall of the groove 21, realizing positioning and initial fastening. If the limiting and fastening effect is insufficient, the second spring 7 can be further compressed by rotating the adjusting nut 4 on the pin 3 to increase the preload, thereby improving the clamping and fixing effect.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
