Abstract
Description
Technical Field
[0001] This utility model relates to the field of racks, and in particular to a convenient rack processing fixture. Background Technology
[0002] In the manufacturing process of rack plates, in order to achieve stable fixation and precise machining of the rack plates, designers usually pre-set some fixing holes or reserved holes on the rack plates. The main function of these reserved holes is to serve as a medium for connection and fixation, so that the rack plates can be firmly installed on the equipment in use. However, these reserved holes bring some unexpected problems during the machining process.
[0003] Specifically, during the cutting and grinding processes of the rack, a large amount of metal shavings and coolant are generated. During the high-speed spraying or splashing process, these shavings and coolant can easily enter the interior of the rack through the reserved holes. Once these shavings and coolant enter the reserved holes, they will cause great difficulties for subsequent cleaning work.
[0004] Therefore, it is necessary to provide a new, easy-to-use rack machining fixture to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a convenient and easy-to-use rack and pinion machining fixture.
[0006] The convenient rack and pinion processing fixture provided by this utility model includes: a base, an air bladder, bolts, and an inflation assembly. The base has a hollow interior design. Hollow connecting posts for positioning rack and pinion pieces are fixedly connected at equal intervals at the top of the base. A rack and pinion piece is sleeved on the outside of several hollow connecting posts. An air bladder is fixedly connected inside the hollow connecting posts and communicates with the interior of the hollow connecting posts. A rubber stopper is fixedly connected to one end of the air bladder. A bolt is threaded to one side of the base. A fixing seat is rotatably connected to one end of the bolt. An inflation assembly is installed inside the base and communicates with the interior of the air bladder.
[0007] Preferably, the inflation assembly includes: a cylinder, a threaded rod, an L-shaped connecting rod, a piston, and a conduit. The cylinder is fixedly connected inside the base, and the threaded rod is rotatably connected inside the base. One end of the threaded rod is threadedly connected to an L-shaped connecting rod. The piston is slidably connected to the inner wall of the cylinder. One side of the piston is fixedly connected to the L-shaped connecting rod. The end of the cylinder away from the piston is connected to the inside of the base. The end of the cylinder near the piston is fixedly connected to a conduit, and the conduit is connected to the outside of the base.
[0008] Preferably, ear plates are symmetrically fixedly connected to one side of the base, and the ear plates are used to connect to the processing equipment.
[0009] Preferably, the airbag is made of an elastic material, and its shape and size are designed to fit tightly inside the hollow connecting column. When the airbag is inflated, it can expand outward evenly, thereby sealing the reserved holes on the rack.
[0010] Preferably, one end of the threaded rod extends out of the base and is fixedly connected to a handle, so that the operator can easily rotate the threaded rod, thereby driving the L-shaped connecting rod and the piston to move within the cylinder, thus inflating and deflating the airbag.
[0011] Preferably, the mounting base is provided with threaded holes that match the bolts so that the bolts can securely fix the mounting base to the base.
[0012] Preferably, the bottom of the fixed base is fixedly connected with an anti-slip pad to increase the friction between the fixed base and the contact surface, prevent the fixture from sliding or shifting during processing, and ensure processing accuracy and safety.
[0013] Compared with related technologies, the convenient rack processing fixture provided by this utility model has the following beneficial effects:
[0014] Highly efficient and stable fixing method: The rack pieces are fixed by the expansion of an air bladder, which is not only simple and quick to operate, but also provides a stable and reliable fixing effect. The elastic pressure of the air bladder can be evenly distributed around the reserved holes of the rack pieces, avoiding the damage that may be caused by traditional clamping methods, while ensuring the stability of the rack pieces during processing.
[0015] Excellent sealing performance: During expansion, the airbag fits tightly between the connecting post and the rack plate, effectively sealing the pre-drilled holes on the rack plate and preventing machining debris and coolant from entering the holes. This design not only protects the internal structure of the rack plate but also reduces the difficulty and time cost of subsequent cleaning work. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0022] Please see Figure 1-3 A convenient rack-plate processing fixture includes: a base 1, an air bladder 3, bolts 5, and an inflation assembly. The base 1 has a hollow interior. Hollow connecting posts 2 for positioning rack plates are fixedly connected at equal intervals to the top of the base 1. Rack plates are sleeved on the outside of several hollow connecting posts 2. Air bladders 3 are fixedly connected inside the hollow connecting posts 2, and the air bladders 3 communicate with the interior of the hollow connecting posts 2. A rubber stopper 4 is fixedly connected to one end of the air bladder 3. Bolts 5 are threaded onto one side of the base 1, and a fixing seat 6 is rotatably connected to one end of the bolts 5. An inflation assembly is installed inside the base 1, and the inflation assembly is connected to the interior of the air bladder 3. The base 1 is symmetrically fixed with ear plates 7 on one side. The ear plates 7 are used to connect with the processing equipment. The airbag 3 is made of elastic material. Its shape and size are designed to fit tightly inside the hollow connecting column 2. When the airbag 3 is inflated, it can expand outward evenly to seal the reserved hole on the rack plate. The fixing seat 6 is provided with threaded holes that match the bolt 5 so that the bolt 5 can firmly fix the fixing seat 6 on the base 1. The bottom of the fixing seat 6 is fixedly connected with an anti-slip pad to increase the friction between the fixing seat 6 and the contact surface, prevent the fixture from sliding or displacing during processing, and ensure processing accuracy and safety.
[0023] It should be noted that: several hollow connecting posts 2 are fixed on the base 1 of the fixture. The design dimensions of these connecting posts match the reserved holes on the rack. Before processing, the operator places the rack on the base 1 and aligns the reserved holes with the hollow connecting posts 2.
[0024] Please see Figure 3The inflation assembly includes: a cylinder 21, a threaded rod 22, an L-shaped connecting rod 23, a piston 24, and a conduit 25. The cylinder 21 is fixedly connected inside the base 1, and the threaded rod 22 is rotatably connected inside the base 1. One end of the threaded rod 22 is threadedly connected to the L-shaped connecting rod 23. The piston 24 is slidably connected to the inner wall of the cylinder 21. One side of the piston 24 is fixedly connected to the L-shaped connecting rod 23. The end of the cylinder 21 away from the piston 24 is connected to the inside of the base 1. The end of the cylinder 21 near the piston 24 is fixedly connected to the conduit 25, which is connected to the outside of the base 1. One end of the threaded rod 22 extends out of the base 1 and is fixedly connected to a handle so that the operator can easily rotate the threaded rod 22, thereby driving the L-shaped connecting rod 23 and the piston 24 to move inside the cylinder 21, realizing the inflation and deflation of the airbag 3.
[0025] It should be noted that: by rotating the threaded rod 22, one end of which extends out of the base 1 and is fixed with a handle, the operator can easily rotate it. The L-shaped connecting rod 23, which is threaded to it, moves inside the base 1. The other end of the L-shaped connecting rod 23 is connected to the piston 24 inside the cylinder 21, so the piston 24 also slides inside the cylinder 21. When the threaded rod 22 rotates, causing the L-shaped connecting rod 23 to move towards one end of the cylinder 21, the piston 24 is pushed towards the other end of the cylinder 21, thereby compressing the air inside the cylinder 21.
[0026] One end of the cylinder 21 is connected to the interior of the base 1, and the other end is connected to the air bladder 3 through the conduit 25. When the piston 24 compresses the air inside the cylinder 21, the compressed air enters the air bladder 3 through the conduit 25, causing the air bladder 3 to expand. The expansion of the air bladder 3 not only makes it fit tightly between the connecting column and the rack plate, but also effectively seals the reserved hole on the rack plate through its elastic pressure, preventing machining debris and coolant from entering.
[0027] The working principle of the convenient rack and pinion machining fixture provided by this utility model is as follows:
[0028] First, a number of hollow connecting posts 2 are fixed on the base 1 of the fixture. The design dimensions of these connecting posts match the reserved holes on the rack. Before processing, the operator places the rack on the base 1 and aligns the reserved holes with the hollow connecting posts 2.
[0029] Next, the air inflation assembly inside the fixture begins to work; by rotating the threaded rod 22 (one end of which extends out of the base 1 and is fixed with a handle for easy rotation by the operator), the L-shaped connecting rod 23, which is threaded to it, moves inside the base 1; the other end of the L-shaped connecting rod 23 is connected to the piston 24 inside the cylinder 21, so the piston 24 also slides inside the cylinder 21; when the threaded rod 22 rotates, causing the L-shaped connecting rod 23 to move toward one end of the cylinder 21, the piston 24 is pushed toward the other end of the cylinder 21, thereby compressing the air inside the cylinder 21;
[0030] One end of the cylinder 21 is connected to the interior of the base 1, and the other end is connected to the air bag 3 through the conduit 25. When the piston 24 compresses the air in the cylinder 21, the compressed air enters the air bag 3 through the conduit 25, causing the air bag 3 to expand. The expansion of the air bag 3 not only makes it fit tightly between the connecting column and the rack, but also effectively seals the reserved hole on the rack through its elastic pressure, preventing machining debris and coolant from entering.
[0031] Meanwhile, the fixing part of the fixture also plays an important role; a bolt 5 is threaded on one side of the base 1, and a fixing seat 6 is rotated on one end of the bolt 5; after the fixture is placed on the processing equipment or workbench, the operator presses the fixing seat 6 tightly against the contact surface by rotating the bolt 5; the fixing seat 6 is equipped with an anti-slip pad to increase the friction between it and the contact surface, ensuring that the fixture will not slide or shift during the processing.
[0032] In this way, the expansion of the airbag 3 achieves the sealing and fixation of the rack piece, and the rotation of the bolt 5 achieves the stable connection between the fixture and the processing equipment or worktable. This fixture can ensure the stability and accuracy of the rack piece during the processing. After processing, the operator only needs to rotate the threaded rod 22 in the opposite direction to release the airbag 3 and loosen the bolt 5 to easily remove the rack piece for subsequent processing.
[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
