[0006] To achieve the above objectives, the present invention provides a grinding and polishing machine tool for mechanical parts, including a support base plate, a shock-absorbing box, a hydraulic cylinder, a mounting plate, a grinding mechanism, and a fixing mechanism. The shock-absorbing box is mounted on the upper surface of the support base plate by a plurality of shock-absorbing springs.

The protective plate is mounted on the side of the slide rail away from the inner wall of the shock-absorbing housing. The sliding seat is slidably mounted on the protective plate. The fixed arm is mounted on the sliding seat. The second servo motor is mounted on one end of the slide rail. The output end of the second servo motor is provided with the second threaded rod. The second ball screw nut assembly is provided on the second threaded rod and is connected to the sliding seat.

[0010] Each of the slide rails is provided with a fixed wing plate on the side closest to the inner wall of the shock-absorbing box, and the fixed wing plate is connected to the inner wall of the shock-absorbing box.

[0011] The grinding and polishing machine tool for mechanical parts also includes two auxiliary support arms. The auxiliary support arms are provided on both sides of the mounting plate.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] First embodiment:

[0026] Please see Figures 1 to 5 ,in Figure 1 This is a schematic diagram of the structure of the grinding and polishing machine tool for mechanical parts according to the first embodiment. Figure 2 yes Figure 1 A magnified view of the local structure at point A. Figure 3 This is a schematic diagram of the disassembled structure of the vertical slide in the first embodiment. Figure 4 yes Figure 3 A magnified view of the local structure at point B. Figure 5 This is a schematic diagram of the disassembled structure of the sliding arm and the fixed arm in the first embodiment.

[0027] This invention provides a grinding and polishing machine tool for mechanical parts, comprising a support base plate 101, a shock-absorbing housing 102, a hydraulic cylinder 103, a mounting plate 104, a grinding mechanism, and a fixing mechanism. The fixing mechanism includes two vertical slides, two fixed arms 105, two drive components, two sliding arms 106, and two clamping plates 107. Each drive component includes a first servo motor 108, a first threaded rod 109, and a first ball screw nut assembly 110. Each vertical slide includes a slide rail 111, a protective plate, a sliding seat 112, a second servo motor 113, a second threaded rod 114, and a second ball screw nut assembly 115. The grinding mechanism includes a drive motor 116, a drive shaft 117, and a grinding wheel 118. This solution solves the problem in existing grinding and polishing machine tools for mechanical parts where grinding debris adheres to the screw, leading to increased mechanical wear and shortening the service life of the entire fixing device. It is understood that the aforementioned solution can be applied to the structure of a grinding and polishing machine tool for mechanical parts.

[0028] In this specific embodiment, the shock-absorbing housing 102 is mounted on the upper surface of the supporting base plate 101 via multiple shock-absorbing springs 119. A placement platform 120 is provided at the bottom of the inner part of the shock-absorbing housing 102. The mounting plate 104 is mounted on the top of the shock-absorbing housing 102 via a hydraulic cylinder 103. The drive motor 116 is mounted on the bottom of the mounting plate 104. The output end of the drive motor 116 is provided with a drive shaft 117. The end of the drive shaft 117 away from the drive motor 116 is provided with a grinding wheel 118. After the mechanical parts to be ground are placed on the placement platform 120, the hydraulic cylinder 103 is activated to adjust the height of the grinding wheel 118 so that the grinding wheel 118 is in contact with the grinding surface of the mechanical parts. Then, the drive motor 116 is activated, and the grinding wheel 118 is rotated through the drive shaft 117, thereby completing the grinding of the mechanical parts.

[0029] The shock-absorbing housing 102 has vertical slides on both sides inside. Each vertical slide has a fixed arm 105 at its output end. A sliding arm 106 is slidably mounted on the end of each fixed arm 105 away from the corresponding vertical slide. Both the sliding arm 106 and the fixed arm 105 are hollow. A driving component is located inside each fixed arm 105. The output end of each driving component is connected to the inner bottom wall of the corresponding sliding arm 106. A clamping plate 107 is mounted on the end of each sliding arm 106 away from the corresponding fixed arm 105. Two clamping plates 107 are located on either side of the placement platform 120. After placing the mechanical parts to be polished on the upper surface of the placement table 120, the height of the fixing arm 105 is adjusted using the vertical slide table so that the two clamping plates 107 are respectively located on both sides of the mechanical parts to be polished. Then, the driving component is activated, driving the sliding arm 106 to slide inside the fixing arm 105, so that the two clamping plates 107 move synchronously towards the mechanical parts. Thus, the mechanical parts are fixed by the cooperation of the two clamping plates 107. With the above structure, since the driving component is installed inside the fixing arm 105, the waste generated during polishing will not affect the operation of the driving component, thereby improving the service life of the entire fixing mechanism.

[0030] Secondly, the first servo motor 108 is installed at the inner bottom of the fixed arm 105. The output end of the first servo motor 108 is provided with the first threaded rod 109. The ball screw nut pair 110 is provided on the first threaded rod 109. The ball screw nut pair 127 is connected to the inner bottom wall of the sliding arm 106. When the first servo motor 108 is started, the first threaded rod 109 is driven to rotate. Since the first ball screw nut pair 110 is connected to the sliding arm 106, the sliding arm 106 is driven to slide inside the fixed arm 105. Each first threaded rod 109 is provided with a limit block 121 at the end away from the corresponding first servo motor 108. The limit block 121 is provided to prevent the first ball screw nut pair 110 from falling off the first threaded rod 109. And since the limit block 121 is located inside the corresponding fixed arm 105, the sliding arm 106 is prevented from falling off the inside of the fixed arm 105.

[0031] Meanwhile, the slide rail 111 is vertically installed on the inner wall of the shock absorber housing 102. A protective plate is installed on the side of the slide rail 111 away from the inner wall of the shock absorber housing 102. A sliding seat 112 is slidably mounted on the protective plate, and a fixed arm 105 is mounted on the sliding seat 112. A second servo motor 113 is installed at one end inside the slide rail 111. A second threaded rod 114 is provided at the output end of the second servo motor 113, and a second ball screw is provided on the second threaded rod 114. The second ball screw nut assembly 115 is connected to the sliding seat 112. When the second servo motor 113 is started, it drives the second threaded rod 114 to rotate. Since the second ball screw nut assembly 115 is connected to the sliding seat 112, the sliding seat 112 slides on the protective plate, thereby adjusting the height of the fixed arm 105. Furthermore, the protective plate protects the end face of the slide rail 111, preventing grinding debris from entering the slide rail 111. The second threaded rod 114 experiences significant mechanical wear. Each protective plate includes a cover plate 122, two inclined plates 123, and two fixing feet 124. The cover plate 122 is located on the side of the slide rail 111 away from the inner wall of the shock-absorbing housing 102. Inclined plates 123 are provided on both sides of the cover plate 122. The ends of the two inclined plates 123 away from the cover plate 122 are located on opposite sides of the end face of the slide rail 111. Fixing feet 124 are provided at both ends of the cover plate 122. 24 is connected to the end of the slide rail 111. The arrangement of the two inclined plates 123 improves the shielding effect of the protective plate on the cross section of the slide rail 111. At the same time, each sliding seat 112 is provided with a through groove 125. The through groove 125 is clearance-fitted with the protective plate. The through groove 125 is provided with multiple mounting holes 126. Each mounting hole 126 is provided with a ball bearing 127. The ball bearing 127 makes the sliding seat 112 slide more smoothly on the protective plate.

[0032] In addition, each slide rail 111 is provided with a fixed wing plate 128 on the side of the inner wall of the shock-absorbing box 102. The fixed wing plate 128 is connected to the inner wall of the shock-absorbing box 102. The fixed wing plate 128 is installed on the inner wall of the shock-absorbing box 102 by screws, thereby completing the installation of the slide rail 111.

[0033] When using a mechanical parts grinding and polishing machine tool according to this embodiment, after placing the mechanical parts to be ground on the upper surface of the placement table 120, the height of the fixed arm 105 is adjusted using the vertical slide table so that the two clamping plates 107 are respectively located on both sides of the mechanical parts to be ground. Then, the drive component is activated, driving the sliding arm 106 to slide inside the fixed arm 105, so that the two clamping plates 107 move synchronously towards the mechanical parts. Thus, the mechanical parts are fixed by the cooperation of the two clamping plates 107. The hydraulic cylinder 103 is activated, and the height of the grinding wheel 118 is adjusted so that the grinding wheel 118 is in contact with the grinding surface of the mechanical parts. Then, the drive motor 116 is activated, driving the grinding wheel 118 to rotate through the drive shaft 117, thereby completing the grinding of the mechanical parts. With the above structure, since the drive component is installed inside the fixed arm 105, the waste generated during grinding will not affect the operation of the drive component, thereby improving the service life of the entire fixing mechanism.

[0034] Second embodiment:

[0035] Based on the first embodiment, please refer to Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the structure of the grinding and polishing machine tool for mechanical parts according to the second embodiment. Figure 7 for Figure 6 A magnified view of the local structure at point C.

[0036] The present invention provides a grinding and polishing machine tool for mechanical parts, which also includes two auxiliary support arms 201.

[0037] In this specific embodiment, auxiliary support arms 201 are provided on both sides of the mounting plate 104. Each auxiliary support arm 201 and one end of the mounting plate 104 are slidably connected to the inner wall of the shock-absorbing box 102. The auxiliary support arms 201 make the structure more stable when the mounting plate 104 is raised and lowered inside the shock-absorbing box 102.

[0038] Each of the auxiliary support arms 201 is provided with a fixing plate 202 and a sliding block 203 at both ends. The inner back of the shock-absorbing box 102 is provided with two sliding grooves 204. The fixing plate 202 is detachably connected to the mounting plate 104. The sliding block 203 slides in the corresponding sliding groove 204. Through the setting of the sliding groove 204 and the sliding block 203, the auxiliary support arm 201 slides inside the shock-absorbing box 102. Through the setting of the fixing plate 202, the connection between the auxiliary support arm 201 and the mounting plate 104 is completed.

[0039] When using a grinding and polishing machine tool for mechanical parts according to this embodiment, the auxiliary support arm 201 slides inside the shock-absorbing housing 102 due to the setting of the slide groove 204 and the sliding block 203. The connection between the auxiliary support arm 201 and the mounting plate 104 is completed by the setting of the fixing plate 202. The setting of the auxiliary support arm 201 makes the structure more stable when the mounting plate 104 moves up and down inside the shock-absorbing housing 102.
