[0019] In order to clearly and completely describe the purpose, technical solution of the present utility model and make its advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are some embodiments of the present utility model, rather than all embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0020] Embodiment 1

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a grinding device for machining mechanical parts, including: a machine cover 1 and a workbench 2. A grinding device 15 is movably arranged at the top end of the inner wall of the machine cover 1. A water tank 11 is opened on the surface of the workbench 2. A plurality of groups of positioning holes 3 are opened at the top end of the workbench 2. A plurality of groups of positioning rods 4 are fixed at the bottom end of the machine cover 1. The plurality of groups of positioning rods 4 are respectively movably inserted into the plurality of groups of positioning holes 3. A limiting groove 7 is opened on the inner wall of the groove body of the positioning hole 3. A limiting block installation groove 5 is opened on the side wall of the positioning rod 4. One end of a limiting block 6 is movably inserted into the limiting block installation groove 5. The other end of the limiting block 6 is movably inserted into the limiting groove 7. An inclined surface is arranged on the bottom surface of the end of the limiting block 6 extending into the limiting groove 7. Hydraulic tappet mechanisms 12 are fixed on the inner walls of the two symmetric groove bodies of the water tank 11. A clamping plate 13 is fixed on the tappet of the hydraulic tappet mechanism 12. A part 14 is arranged between the two clamping plates 13.

[0022] During actual use, in the initial state, the machine cover 1 and the workbench 2 are in a separated state. At this time, the part 14 is placed in the water tank 11 opened on the surface of the workbench 2. By the elongation of the tappet of the hydraulic tappet mechanism 12, the part 14 is clamped between the two clamping plates 13. Then, the machine cover 1 is placed above the workbench 2. When placing, the positioning rod 4 is inserted into the positioning hole 3. When the inclined surface of the limiting block 6 contacts the workbench 2, the limiting block 6 is completely pushed into the limiting block installation groove 5. Until the limiting block installation groove 5 is aligned with the limiting groove 7, one end of the limiting block 6 is inserted into the limiting groove 7 and the other end remains in the limiting block installation groove 5, thereby limiting the positioning rod 4 in the positioning hole 3, providing a positioning function for the machine cover 1, and preventing the machine cover 1 from shifting when the reaction force of the part 14 on the grinding device 15 is transmitted to the machine cover 1 during the grinding of the part 14 by the grinding device 15.

[0023] Embodiment 2

[0024] On the basis of the first embodiment, in order to realize that one end of the limiting block 6 automatically inserts into the limiting groove 7 after the limiting block installation groove 5 is aligned with the limiting groove 7, a spring 10 is fixed at one end of the limiting block 6 extending into the limiting block installation groove 5, and the other end of the spring 10 is fixed on the inner wall of the groove body of the limiting block installation groove 5.

[0025] When the limiting block 6 is completely retracted into the limiting block installation groove 5, the spring 10 is in a compressed state. The spring 10 generates a thrust force on the limiting block 6 to extend out of the limiting block installation groove 5 under the action of its own elastic force. Therefore, when the limiting block installation groove 5 is aligned with the limiting groove 7, the thrust force of the spring 10 on the limiting block 6 causes one end of the limiting block 6 to extend out of the limiting block installation groove 5 and insert into the limiting groove 7.

[0026] The third embodiment

[0027] On the basis of the second embodiment, in order to facilitate the disassembly of the hood 1, a button 9 is movably inserted on the surface of the workbench 2. One end of the button 9 extends into the limiting groove 7, and a push plate 8 is fixed at the end of the button 9 extending into the limiting groove 7.

[0028] After grinding, press the button 9 to push the push plate 8 in the direction close to the positioning rod 4 at the end of the button 9 extending into the limiting groove 7. The movement of the push plate 8 pushes the limiting block 6 out of the limiting groove 7, so that the limiting of the positioning hole 3 to the positioning rod 4 can be released, and then the hood 1 can be lifted upward to make the positioning rod 4 withdraw from the positioning hole 3, facilitating the disassembly of the hood 1.

[0029] The fourth embodiment

[0030] On the basis of the third embodiment,

[0031] During actual use, in the initial state, the hood 1 and the workbench 2 are in a separated state. At this time, the part 14 is placed in the water tank 11 opened on the surface of the workbench 2. Through the elongation of the tappet of the hydraulic tappet mechanism 12, the part 14 is clamped between two groups of clamping plates 13. Then, the hood 1 is placed above the workbench 2. When placing, the positioning rod 4 is inserted into the positioning hole 3. When the inclined surface of the limit block 6 contacts the workbench 2, the limit block 6 is completely pushed into the limit block installation groove 5. Until the limit block installation groove 5 is aligned with the limit groove 7, one end of the limit block 6 is inserted into the limit groove 7 and the other end remains in the limit block installation groove 5, thereby limiting the positioning rod 4 in the positioning hole 3, so as to provide a positioning function for the hood 1, and prevent the hood 1 from displacing when the reaction force of the part 14 on the grinding device 15 is transmitted to the hood 1 during the grinding of the part 14 by the grinding device 15; when the limit block 6 is completely retracted into the limit block installation groove 5, the spring 10 is in a compressed state. The spring 10 generates a thrust on the limit block 6 to extend out of the limit block installation groove 5 under its own elastic force. Therefore, when the limit block installation groove 5 is aligned with the limit groove 7, the thrust of the spring 10 on the limit block 6 causes one end of the limit block 6 to extend out of the limit block installation groove 5 and insert into the limit groove 7; after grinding, press the button 9, so that the end of the button 9 extending into the limit groove 7 pushes the push plate 8 in the direction close to the positioning rod 4. The movement of the push plate 8 pushes the limit block 6 out of the limit groove 7, and the limit of the positioning hole 3 on the positioning rod 4 can be released. Then, the hood 1 can be lifted upward to make the positioning rod 4 withdraw from the positioning hole 3, and the disassembly of the hood 1 can be conveniently completed.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
