Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] In some embodiments, please refer to the appendix to the instruction manual. Figures 1-4 A fixture for machining holes in grating blades that is easy to position includes a frame 100 and a positioning component 200. The positioning component 200 is mounted on the frame 100 and is used to clamp the grating blades at multiple points. The positioning component 200 includes a set of clamping rods 210 arranged in a ring. A set of support rods 211 evenly distributed along the axis of the clamping rods 210 are hinged to the clamping rods 210. One end of the support rods 211 is hinged to a bonding plate 212. A hydraulic rod 130 is mounted on the frame 100. A detachable cutter head 131 is installed at the bottom end of the hydraulic rod 130.

[0029] In this embodiment of the utility model, when machining holes in the grating blade, the user can select and replace the corresponding cutter head 131 according to the machining requirements of the grating blade. Then, the grating blade is placed on the frame 100, and then the positioning component 200 is used to position it. Then, the hydraulic rod 130 is activated to drive the cutter head 131 to machine the holes in the grating blade.

[0030] In this embodiment of the utility model, during the positioning process, a multi-point clamping rod 210 is used to clamp and fix the top of the grating blade, making the force distribution more uniform. At the same time, a multi-point displacement support rod 211 is used to disperse the pressure on the clamping point area. The bonding plate 212 is used to transform the pressure from point to surface, effectively alleviating the phenomenon of local stress concentration during the clamping process. While ensuring the positioning effect, it reduces the deformation of the grating blade during subsequent processing.

[0031] In some embodiments, such as Figure 1 and Figure 3 As shown, in a preferred embodiment of the present invention, one end of the clamping rod 210 is provided with a riser 213, and the inside of the riser 213 is slidably connected to a piston plate 214 which is fixedly connected to one end of the clamping rod 210. A connecting pipe 215 is installed between two adjacent risers 213.

[0032] During the clamping and positioning process, gas can be introduced into the connecting pipe 215, and then the gas is distributed to the interior of each riser 213. Then, the corresponding piston plate 214 is pushed to drive the clamping rod 210 to complete the positioning. The uniform distribution of gas ensures that the pressure at each point is the same, reducing the occurrence of inconsistent pressure.

[0033] In this embodiment of the utility model, a clamping ring 216 is threaded on the outer side of the clamping rod 210. The clamping ring 216 is located above the support rod 211. The user can rotate the clamping ring 216 to limit the position of the support rod 211 and reduce the phenomenon of the support rod 211 accidentally tilting upward during the pressure application process.

[0034] In this embodiment of the utility model, a miniature air pump 110 is installed on the frame 100. The output end of the miniature air pump 110 is connected to a conduit 111 that communicates with one of the connecting pipes 215. An exhaust pipe is installed on the connecting pipe 215, and a valve is provided on the outside of the exhaust pipe. When the miniature air pump 110 is started, external gas can be introduced into the connecting pipe 215 along the conduit 111. After positioning is completed, the gas in the riser 213 can be discharged along the exhaust pipe on the connecting pipe 215.

[0035] In this embodiment of the utility model, a horizontal tube 217 is provided on the outside of the riser 213, and a push plate 218 is slidably connected inside the horizontal tube 217. A connecting rod 219 is provided between the push plate 218 and the riser 213. When positioning grating blades of different sizes, the user can drive the push plate 218 to make the connecting rod 219 drive the riser 213 to move, thereby adjusting the pressing point and making it suitable for grating blades of different sizes.

[0036] In this embodiment of the utility model, an electric push rod 120 is provided at the bottom of the frame 100. A receiving plate 121 is installed at one end of the electric push rod 120. A traction rope 122 is provided between the receiving plate 121 and the push plate 218, passing through the frame 100 and the horizontal tube 217 in sequence. When the electric push rod 120 extends, the receiving plate 121 can pull the traction rope 122, thereby pulling the push plate 218 and completing the adjustment of the pressing point.

[0037] In this embodiment of the utility model, springs 300 are provided inside both the vertical tube 213 and the horizontal tube 217. One end of each spring 300 is fixedly connected to the outer side of the piston plate 214 and the push plate 218, respectively. One spring 300 is sleeved on the outer side of the connecting rod 219. When the electric push rod 120 retracts, the receiving plate 121 no longer applies pressure to the traction rope 122. Subsequently, the spring 300 in the horizontal tube 217 deforms and resets, thereby driving the push plate 218 to move and completing the reverse adjustment of the pressing point.

[0038] After the positioning operation is completed, the spring 300 inside the riser 213 will deform and return to its original position, thereby venting the gas inside the riser 213 and simultaneously resetting the clamping rod 210, making it easier to perform the next positioning operation.

[0039] In this embodiment of the utility model, the connecting pipe 215 is made of plastic flexible tubing, which allows each vertical pipe 213 to move normally during the adjustment of the positioning area and prevents jamming. The spring 300 inside the horizontal pipe 217 is in a stretched state, which allows the spring 300 to deform itself to drive the push plate 218 to complete the adjustment of the pressing point when the traction rope 122 is not pulling.

[0040] In this embodiment of the utility model, a set of columns are provided on the frame 100, and the horizontal tube 217 is installed on the frame 100 through the columns, and the columns support the horizontal tube 217.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
