Description

Technical Field

[0001] This utility model relates to the field of workpiece grinding technology, and in particular to a grinding fixture. Background Technology

[0002] Grinding workpieces is done to meet assembly, safety, and precision requirements: removing sharp edges to avoid scratches during operation, ensuring a good fit between parts, and improving appearance consistency. During grinding, the rotating grinding wheel comes into contact with the workpiece, generating impact and friction. If not fixed in place, the workpiece can easily shift, leading to deviations in grinding dimensions and inaccurate angles.

[0003] In traditional angle grinding processes, the fixation of workpieces requiring angle grinding mostly relies on the coordinated operation of two clamping joints: one clamping joint is moved and adjusted to a suitable position, and then it works together with the other clamping joint to hold and fix the workpiece in place. However, because the angle of the fixture fixing the workpiece is fixed and cannot be adjusted, the fixture has poor adaptability and cannot flexibly adjust the angle of the workpiece according to the actual angle grinding requirements, thus limiting the flexibility and applicability of the processing. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the angle of the fixture for fixing the workpiece in the prior art is fixed and cannot be adjusted, resulting in poor adaptability of the fixture and the inability to flexibly adjust the angle of the workpiece according to the actual grinding requirements, which limits the processing flexibility and scope of application. Therefore, a grinding fixture is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A grinding fixture includes a clamping platform, on which a push rod is slidably connected horizontally. One end of the push rod is fixedly connected to a clamping connector. A perforated plate is fixedly provided on the clamping connector. The perforated plate has a first fixing hole and several second fixing holes arranged in a fan shape. A first stop rod is horizontally inserted into the first fixing hole, and a second stop rod is horizontally inserted into the second fixing hole. A baffle is rotatably sleeved on the first stop rod, and the baffle and the second stop rod are in contact.

[0006] Preferably, a limiting block is fixedly connected to the bottom end of the card connector, and the limiting block and the card platform are horizontally slidably connected.

[0007] Preferably, the card plate has a sliding opening to facilitate the horizontal sliding of the card connector, and the card plate has a limiting groove to facilitate the horizontal sliding of the limiting block.

[0008] Preferably, the baffle plate has an insertion hole for easy fitting onto the first baffle rod.

[0009] Preferably, the snap-fit ​​connector is fixedly connected with a plurality of connecting ears, and the connecting ears and the hole plate are threadedly connected with the same bolt.

[0010] Preferably, a handle is fixedly connected to the end of the push rod away from the card connector.

[0011] Compared with the prior art, the advantages of this utility model are as follows: This utility model, through the setting of components such as the perforated plate, allows for the smooth pushing of the push rod and the clamping joint to clamp and fix the workpiece. At the same time, the second stop rod can be inserted into different second fixing holes to make the baffle and the workpiece tilt together, thereby adjusting the angle of the baffle and thus realizing the adjustment of the workpiece angle, and thus realizing the grinding of the workpiece at different angles.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-4A grinding fixture includes a clamping platform 1, which serves as the basic load-bearing structure of the fixture, providing stable support for the overall components. A push rod 2 is horizontally slidably connected to the clamping platform 1. This horizontal sliding connection design ensures smooth sliding of the push rod 2 in the horizontal direction, preventing offset and ensuring accurate workpiece positioning. A clamping connector 3 is fixedly connected to one end of the push rod 2. The clamping connector 3, as the core connecting component, provides the mounting base for components such as a baffle 45 through its fixed installation with a perforated plate 4. A perforated plate 4 is fixedly installed on the clamping connector 3. The perforated plate 4 has a first fixing hole 41 and several fan-shaped second fixing holes 42. These fan-shaped second fixing holes 42 allow for flexible adjustment of the insertion position of the second baffle 44 according to the grinding requirements of different workpieces. Through the contact between the second baffle 44 and the baffle 45, the tilt angle of the baffle 45 can be precisely adjusted, greatly improving the fixture's adaptability to workpieces of different specifications. A first stop rod 43 is horizontally inserted into the first fixing hole 41, and a second stop rod 44 is horizontally inserted into the second fixing hole 42. This plug-in design facilitates quick disassembly and replacement of the stop rods, reducing maintenance costs. A baffle 45 is rotatably fitted onto the first stop rod 43, and the baffle 45 contacts the second stop rod 44. This rotatable fitting allows for flexible rotation around the first stop rod 43 to adjust the angle, while also providing stable positioning through contact with the second stop rod 44, ensuring that the baffle 45 does not deviate during the grinding process and improving positioning reliability.

[0016] The bottom end of the card connector 3 is fixedly connected to the limiting block 5, and the limiting block 5 and the card platform 1 are horizontally slidably connected.

[0017] The clamping platform 1 has a sliding opening 51 to facilitate the horizontal sliding of the clamping connector 3, and a limiting groove 52 to facilitate the horizontal sliding of the limiting block 5. The sliding opening 51 provides a precise trajectory for the horizontal sliding of the clamping connector 3, preventing it from wobbling left and right during sliding; the limiting groove 52 constrains the sliding of the limiting block 5, preventing the clamping connector 3 from tilting upward or shifting due to uneven force during sliding, thus enhancing the stability and accuracy of the horizontal sliding of the clamping connector 3 and ensuring the consistency of the workpiece positioning position.

[0018] The baffle 45 has an insertion hole 46 for easy insertion onto the stop rod 43. The diameter of the insertion hole 46 precisely matches the diameter of the stop rod 43, ensuring smooth installation of the baffle 45 while minimizing gaps after installation and preventing radial wobble during use. The design of the insertion hole 46 allows the baffle 45 to be quickly removed from or installed on the stop rod 43, facilitating the replacement of baffles 45 of different sizes according to workpiece specifications, thus improving the versatility and operational efficiency of the fixture.

[0019] Several connecting ears 7 are fixedly connected to the clamp connector 3, and the connecting ears 7 and the hole plate 4 are threadedly connected by the same bolt 8. The threaded connection of the bolt 8 is not only reliable, but also facilitates disassembly and maintenance in the future. When the hole plate 4 or the clamp connector 3 is worn, the parts can be quickly replaced by loosening the bolt 8, reducing the difficulty of maintenance.

[0020] A handle 6 is fixedly connected to the end of the push rod 2 away from the locking connector 3. The handle 6 increases the force application area of ​​the hand and conforms to ergonomic design. The operator can easily push the push rod 2 by holding the handle 6, thereby driving the locking connector 3 to flexibly adjust its position and improving the convenience of operation.

[0021] The functional principle of this utility model can be explained through the following operation methods: When using this angle grinding fixture, first securely install the hole plate 4 onto the snap-fit ​​connector 3 by connecting the ear 7 to the bolt 8 on the hole plate 4.

[0022] Next, insert the first stop rod 43 into the first fixing hole 41 of the perforated plate 4, so that the baffle 45 can be fitted onto the first stop rod 43 through the insertion hole 46 and can rotate. Then, select a suitable position from the fan-shaped second fixing holes 42 and insert the second stop rod 44 so that the baffle 45 contacts the second stop rod 44 for positioning.

[0023] During operation, after the workpiece is placed on the baffle 45, hold the handle 6 at the end of the push rod 2 and push the clamping connector 3 horizontally.

[0024] The card connector 3 slides horizontally along the sliding opening 51 of the card platform 1, while the limiting block 5 at its bottom slides synchronously within the limiting groove 52 to ensure smooth sliding.

[0025] Adjust the position until the hole plate 4 and the clamping table 1 clamp the workpiece to be ground. Then, the external grinding tool can be used to grind the workpiece. By inserting the second stop rod 44 into different second fixing holes 42, the baffle 45 and the workpiece can be tilted together, thereby further ensuring the accuracy of grinding.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
