DETAILED DESCRIPTION

[0023] 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.

[0024] Example 1

[0025] like Figure 1 As shown:

[0026] A gear processing fixture comprises a mounting seat 1.

[0027] In this embodiment: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "Currently in the process of clamping gears, when facing different gear processing, different types of clamps are needed to clamp the gears, which not only increases the processing cost, but also is time-consuming and labor-intensive, and generally the gears are fixed by manually turning the extrusion bolts, which is cumbersome during the disassembly and assembly process, reducing the use effect of the device." In terms of use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a clamping assembly 2 and a supporting assembly 3 are added to the application document.

[0028] More specifically:

[0029] like Figure 1-Figure 5 As shown:

[0030] A clamping assembly 2 is installed on the mounting seat 1, and the clamping assembly 2 includes a hydraulic push rod 201 fixedly installed inside the mounting seat 1 by bolts, a guide rod 213 fixed to the output end of the hydraulic push rod 201, and a moving block 202 fixed to the top of the guide rod 213. Four groups of expansion rods 208 arranged equidistantly in a ring are arranged above the moving block 202. A connecting plate 207 is fixed to the bottom end of the expansion rod 208, and a moving plate 204 is fixed to one side of the connecting plate 207. A rectangular groove is opened on one side of the surface of the mounting seat 1 close to the moving plate 204, and a limiting rod 203 is arranged in the rectangular groove. The moving plate 204 is slidably connected to the limiting rod 204 through the through hole opened. 03, a spring 205 is wound around the surface of the limit rod 203, and the two ends of the spring 205 are fixedly connected to the moving plate 204 and the mounting seat 1 respectively. An extrusion block 206 is fixed on the side of the moving plate 204 close to the moving block 202, and the moving plate 204 and the mounting seat 1 are slidably connected through this rectangular groove, and the side where the extrusion block 206 and the moving block 202 are close to each other are both designed with inclined surface structures and fit tightly, and a through hole compatible with the guide rod 213 is opened on the surface of the mounting seat 1, and the guide rod 213 and the mounting seat 1 are slidably connected through this through hole, and mounting holes are opened at the four corners of the bottom of the mounting seat 1, and the mounting seat 1 is provided with fastening bolts 212 through the mounting holes.

[0031] In this embodiment, when the gear processing fixture is used to clamp and fix the gear, the axial center hole of the gear to be clamped (not shown in the figure) is first aligned with the four groups of expansion rods 208, and is sleeved on the outside of the expansion rods 208, and then the hydraulic push rod 201 is started, thereby driving the guide rod 213 to move up, and the guide rod 213 drives the moving block 202 to move up synchronously. Since the four sides of the moving block 202 are designed with inclined surfaces, when the moving block 202 moves up, it squeezes the extrusion block 206, so that the four groups of extrusion blocks 206 expand outward, and through the movement of the extrusion block 206, it drives The movable plate 204 moves on the limit rod 203 and stretches the spring 205 at the same time. At this time, the movable plate 204 moves and drives the connecting plate 207 to move. The connecting plate 207 drives the expansion rod 208 to expand outward, so that the four groups of expansion rods 208 are used to fix the gear in an expanded form. Through this operation, gears of different sizes can be fixed without replacing the clamps, reducing costs. This fixing method is more convenient, simple and practical, improves the efficiency of disassembly and assembly of the gears, and has a better use effect. The mounting base 1 can be installed in the specified position by tightening the bolts 212.

[0032] Going further;

[0033] In an optional embodiment, a fixed plate 210 is fixed to a side of the upper surface of the mounting base 1 close to the movable plate 204 , and a telescopic rod 211 is fixed between the fixed plate 210 and the movable plate 204 .

[0034] In this embodiment, while the movable plate 204 moves, the telescopic rod 211 is compressed. By setting the telescopic rod 211 and the fixed plate 210, the stability of the movement of the movable plate 204 can be increased, and the limiting effect of the movable plate 204 can be achieved.

[0035] Going further;

[0036] In an optional embodiment, the exterior of the four groups of expansion rods 208 is designed with an arc-shaped surface structure, and the exterior of the expansion rods 208 is provided with anti-slip teeth 209, and one group of anti-slip teeth 209 of the symmetrically arranged expansion rods 208 is designed with a vertical structure, and the other group of anti-slip teeth 209 of the symmetrically arranged expansion rods 208 is designed with a horizontal structure.

[0037] In this embodiment: the lateral and vertical friction between the gear and the expansion rod 208 can be increased, the fixing effect of the gear is improved, and slippage is less likely to occur during the processing.

[0038] Further,

[0039] In an optional embodiment, a support assembly 3 is installed on the mounting seat 1, and the support assembly 3 includes a threaded rod 304 arranged between each two groups of fixed plates 210, a threaded cylinder 305 threadedly connected to the surface of the threaded rod 304, and a support plate 306 fixed to the top of the threaded cylinder 305 by bolts, a telescopic rod 2 307 is fixed between the support plate 306 and the mounting seat 1, the threaded rod 304 is rotatably connected to the mounting seat 1 through a bearing, a gear 2 303 is fixed to the bottom end of the threaded rod 304 by screws, a rotating cylinder 301 is rotatably connected to the side of the mounting seat 1 close to the guide rod 213 through a bearing, the rotating cylinder 301 is sleeved on the outside of the guide rod 213, and a gear 1 302 is fixed to the outer surface of the rotating cylinder 301 by screws, and the four groups of gear 2 303 are meshed and connected with gear 1 302.

[0040] In this embodiment, when the gear is sleeved on the outside of the four expansion rods 208, the rotating cylinder 301 is rotated, and the rotation of the rotating cylinder 301 drives the gear 1 302 to rotate. Since the gear 1 302 and the four gears 2 303 are meshed and connected, the gear 2 303 is driven to rotate, and the threaded rod 304 is driven to rotate through the gear 2 303. Since the threaded cylinder 305 is limited by the telescopic rod 2 307, the threaded cylinder 305 is driven to move downward while the threaded cylinder 305 is rotated. Through the downward movement of the threaded cylinder 305, the support plate 306 is driven to move downward until the support plate 306 is supported. The support plate 306 is adjusted to a suitable height. When the gear is sleeved on the outside of the expansion rod 208, the support plate 306 supports the gear so that the gear is in a horizontal state, avoiding hand-held fixation, which makes the gear tilted and affects the later processing effect. At the same time, it also supports the gear to prevent the gear from sliding down. The threaded tube 305 moves on the threaded rod 304 to achieve different height adjustments of the support plate 306, so as to adapt to gears of different sizes and thicknesses for support, ensuring that the expansion rod 208 contacts the side wall of the gear axis hole with the maximum area, thereby improving the stability of the gear fixation.

[0041] Going further;

[0042] In an optional embodiment, an anti-slip groove is provided on the surface of the rotating cylinder 301 .

[0043] In this embodiment, since the anti-skid grooves are provided on the surface of the rotating cylinder 301 , the friction between the rotating cylinder 301 and the rotating cylinder 301 is increased, so that the manual rotation effect of the rotating cylinder 301 is better.

[0044] The working principle and use process of the utility model are as follows: when the gear processing fixture is used to clamp and fix the gear, first, the axial center hole of the gear to be clamped (not shown in the figure) is aligned with the four groups of expansion rods 208, and is sleeved on the outside of the expansion rods 208, and then the hydraulic push rod 201 is started, thereby driving the guide rod 213 to move up, and the guide rod 213 drives the moving block 202 to move up synchronously. Since the four sides of the moving block 202 are designed with inclined surfaces, when the moving block 202 moves up, the extrusion block 206 is squeezed, so that the four groups of extrusion blocks 206 expand outward, and through the movement of the extrusion block 206, the moving plate 204 is driven to move on the limit rod 203, and the spring 205 is stretched at the same time. At this time, the moving plate 204 moves at the same time , and drives the connecting plate 207 to move, and drives the expansion rod 208 to expand outward through the connecting plate 207, so that the four groups of expansion rods 208 are used to fix the gear in an expanded form. Through this operation, gears of different sizes can be fixed without replacing the clamp, which reduces the cost. This fixing method is more convenient, simple and practical, improves the efficiency of disassembly and assembly of the gear, and has a better use effect. While the movable plate 204 moves, the telescopic rod 211 is compressed. Through the arrangement of the telescopic rod 211 and the fixed plate 210, the stability of the movement of the movable plate 204 can be increased, and the limiting effect of the movable plate 204 can be achieved. The outside of the expansion rod 208 is provided with anti-slip teeth 209, and a group of anti-slip teeth of the expansion rod 208 are symmetrically arranged. 209 is designed as a vertical structure, and another group of anti-skid teeth 209 of the expansion rod 208 is symmetrically arranged and designed as a horizontal structure, so that the horizontal and vertical friction between the gear and the expansion rod 208 can be increased, and the fixing effect of the gear is improved. During the processing, it is not easy to slip. When the gear is sleeved on the outside of the four groups of expansion rods 208, by rotating the rotating cylinder 301, since the surface of the rotating cylinder 301 is provided with an anti-skid groove, the friction between it and the rotating cylinder 301 is increased, so that the manual rotation effect of the rotating cylinder 301 is better. By rotating the rotating cylinder 301, the gear 1 302 is driven to rotate. Since the gear 1 302 is meshed and connected with the four groups of gears 2 303, the gear 2 303 is driven to rotate. The threaded rod 304 is driven to rotate. Since the threaded cylinder 305 is limited by the telescopic rod 207, the threaded rod 304 rotates and drives the threaded cylinder 305 to move downward. The threaded cylinder 305 moves downward and drives the support plate 306 to move downward until the support plate 306 is adjusted to a suitable height. When the gear is sleeved on the outside of the expansion rod 208, the support plate 306 supports the gear so that the gear is in a horizontal state to avoid hand-held fixation, which makes the gear tilted and affects the later processing effect. At the same time, it also supports the gear to prevent the gear from sliding down. The threaded cylinder 305 moves on the threaded rod 304 to achieve different height adjustments of the support plate 306, so as to adapt to gears of different sizes and thicknesses for support.This ensures that the expansion rod 208 contacts the side wall of the gear shaft hole with the maximum area, thereby improving the stability of the gear fixation.
