Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing technology, specifically a grinding device for automotive parts manufacturing. Background Technology

[0002] According to the patent document with authorization announcement number "CN208147560U" and invention title "A Grinding Device for Automobile Parts Production", the description states that during use, automobile parts are placed on a worktable. A spring drives a slider via a second electric telescopic rod, which in turn moves a fixed block. A hydraulic cylinder moves the fixed block downwards. During movement, a pressure sensor detects the pressure of the L-shaped block on the part to prevent excessive pressure from the hydraulic cylinder, which could prevent it from moving, or insufficient pressure, which could cause instability. The first electric telescopic rod pushes the part to move, and a motor starts to grind the grinding roller. However, the following defects still exist:

[0003] Because there are many types of automotive parts, including cylindrical parts and plate-shaped parts, it is often easier to clamp plate-shaped parts when using a cylinder, while cylindrical parts may move during clamping, resulting in poor grinding stability and reduced grinding effect.

[0031] Working principle: When grinding cylindrical parts such as shafts, one end of the part is placed between the four clamping heads 2055. Then, each drive motor 2057 is turned on, which drives the rotating screw 2056 to rotate, thereby driving the clamping heads 2055 to move towards the part until all four clamping heads 2055 are in contact with the outer wall of the part, thus achieving the purpose of clamping.

[0032] When grinding of plate-shaped parts is required, the servo motor 20610 is turned on, causing the double-ended screw 2069 to rotate. Since the two sliders 2067 are threadedly connected to the two threaded grooves with opposite directions on the double-ended screw 2069, the two longitudinal connecting plates 2062 are driven to move closer to each other. The rack 2063 meshes with the gear 2061, thereby driving the rotating shaft 2052 to rotate, causing the upper and lower sliding boxes 2053 to rotate to a horizontal state. Then, the plate-shaped parts are placed between the clamping heads 2055 on both sides, and the drive motor 2057 is turned on, causing the clamping heads 2055 to move toward the parts, so that the four clamping heads 2055 clamp the parts.

[0033] When the columnar component is clamped, the four sliding boxes 2053 form an X shape. At this time, the two longitudinal connecting plates 2062 contact the two outer positioning blocks 2064 respectively. When the plate-shaped component is clamped, the sliding boxes 2053 are in a horizontal state, and the longitudinal connecting plates 2062 contact the inner positioning blocks 2065.

[0034] After being fixed, the mounting bracket 301 is driven to move laterally by the sliding module 305, and the mounting bracket 301 is driven to move longitudinally by the support cylinder 303, so that the grinding block on the grinding equipment 302 can contact the part to be ground and then grind. When it is necessary to grind the circumferential position of the part, the rotating motor 204 is turned on to drive the turntable 201 to rotate and adjust the circumferential position of the part.
