Description

Technical Field

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

[0002] Automotive parts refer to the various units that make up a car and the products that serve the car. These parts play a vital role in the production, maintenance and repair of automobiles. There are many types of automotive parts, covering many aspects such as the engine, transmission system, braking system, steering system, running system, and electrical system. Most automotive parts are produced by stamping, and their surfaces or seams have burrs. In order for the parts to meet the usage standards, these burrs need to be polished. The traditional polishing method is to polish one side and then remove the part to polish the other side. This disassembly and assembly is relatively troublesome and time-consuming, which affects the polishing efficiency. In order to improve this situation, a precision polishing device for intelligent manufacturing of automotive parts is proposed.

[0003] For example, the precision grinding device for intelligent manufacturing automotive parts disclosed in the authorization announcement number CN113305671B includes a base plate and a grinding table. The grinding table is fixed to the rear side of the upper end of the base plate. A sliding groove is opened on the front side of the upper end of the base plate. A slider is provided at the upper end of the sliding groove. The lower end of the slider extends into the sliding groove and is slidably connected thereto. A screw is embedded in the sliding groove. The screw passes through the front and rear sides of the slider and is threadedly connected thereto. A top plate is fixedly connected to the upper end of the slider. The rear end of the top plate is an open end. Fixed blocks are fixedly connected to both the upper and lower ends of the top plate. Clamping rings are hinged to the rear ends of the fixed blocks. Although it achieves the goal of placing tubular automotive parts in two clamping rings, which clamp the parts by external torsion springs, and then rotating the handle to move the slider backward so that it contacts the rotating abrasive disc for grinding, while the abrasive disc rotates at the same time, the second fan rotates with the abrasive disc to concentrate the burrs scattered during grinding in the grinding groove, and the first fan in the top plate blows the burrs inside the parts into the grinding groove, so that the burrs enter the pressure groove through the through hole, and then the pressure plate squeezes the burrs into shape. The liquid outlet can store adhesive and other molding agents, which makes it easier to form burrs, thus reducing burr splashing, and making the collection and transportation of burrs very convenient. However, the existing grinding devices do not solve the problems of inconvenient linkage, centering, clamping and fixing of parts, and circumferential rotation for adjusting the grinding position. They are also not suitable for adapting to long shaft parts of different diameters and reducing the time for disassembling and replacing parts, thus affecting the grinding efficiency. Utility Model Content

[0008] Preferably, the clamping structure has three clamping arms, namely a first clamping arm, a second clamping arm, and a third clamping arm; The linkage structure has two parts, namely the left linkage arm and the right linkage arm; The driving component is a push rod and is connected to the third clamping arm; The first clamping arm is rotatably connected to the first movable shaft, the second clamping arm is rotatably connected to the second movable shaft, and the third clamping arm is rotatably connected to the pin.

[0009] Preferably, the first clamping arm, the second clamping arm, and the third clamping arm are each provided with a roller at one end near the center area of ​​the mounting base.

[0011] Preferably, both the left and right linkage arms are arc-shaped, and the gear transmission component is ring-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the grinding device not only realizes convenient linkage centering clamping and fixing of parts and circumferential rotation adjustment of grinding position, which facilitates the adaptation of long shaft parts of different diameters and reduces the time for disassembling and replacing parts, but also improves the grinding efficiency. (1) Insert the long shaft type parts between the three sets of rollers. The drive unit drives the push arm to move.

The second clamping arm drives the right linkage arm to rotate. The right linkage arm drives the first clamping arm to rotate around the first movable shaft. So that the first clamping arm, the second clamping arm and the third clamping arm drive the rollers to rotate synchronously towards the center position of the rotating plate. So that the rollers contact the outer wall of the long shaft type workpiece and clamp and fix it. Then turn on the grinder and grind the parts with the help of the grinder drive structure. This realizes convenient linkage centering clamping and fixing of parts, which is convenient for adapting to long shaft type parts of different diameters. (2) After one side of the component is polished, the drive drives the gear to rotate. Under the mutual meshing of the gear and the gear transmission component, the gear drives the gear transmission component to rotate, and the gear transmission component drives the rotating plate and the component to rotate, thereby rotating and adjusting the polishing position of the component. This reduces the time for disassembling and replacing the component, improves the polishing efficiency, and realizes convenient circumferential rotation adjustment of the polishing position, which facilitates reducing the time for disassembling and replacing the component and improves the polishing efficiency.

[0017] After one side of the component is polished, the driver 17 is turned on, which drives the gear 18 to rotate. Under the mutual meshing of the gear 18 and the gear transmission component 16, and the limiting sliding cooperation between the limiting wheel 19 and the gear transmission component 16, the gear 18 drives the gear transmission component 16 to rotate, which in turn drives the rotating plate 5 and the component to rotate, thereby adjusting the polishing position of the component. This reduces the time for disassembling and replacing the component, improves polishing efficiency, and realizes convenient circumferential rotation adjustment of the polishing position, which facilitates reducing the time for disassembling and replacing components and improves polishing efficiency.

[0018] Preferably, the driver 17 is connected to the gear transmission component 16 via a gear 18, and the mounting base 4 is evenly distributed with four sets of limiting wheels 19 that slide in cooperation with the gear transmission component 16.

[0019] Preferably, the centering clamping assembly further includes a rotating plate 5 disposed on the gear transmission component 16. The rotating plate 5 is provided with multiple clamping structures, a linkage structure rotatably connected between adjacent clamping structures, and a driving component 12 capable of synchronously driving multiple clamping structures to center and clamp or disengage from the components.

[0020] Preferably, the clamping structure has three clamping structures, namely the first clamping arm 6, the second clamping arm 10, and the third clamping arm 15. There are two linkage structures, namely the left linkage arm 11 and the right linkage arm 8. The driving component 12 is a push rod and is connected to the third clamping arm 15 for transmission. The first clamping arm 6 is rotatably connected to the first movable shaft 7, the second clamping arm 10 is rotatably connected to the second movable shaft 9, and the third clamping arm 15 is rotatably connected to the pin 21.

[0021] Preferably, the first clamping arm 6, the second clamping arm 10 and the third clamping arm 15 are each provided with a roller 20 at one end near the center area of ​​the mounting base 4.

[0022] Preferably, the third clamping arm 15 has a hinge shaft 14 at the end away from the roller 20, the driving member 12 is rotatably connected to the hinge shaft 14 through the push arm 13, and the left linkage arm 11 is rotatably connected to the hinge shaft 14.

The outer wall of the workpiece is clamped and fixed. Then, the grinding machine 3 is turned on, and the parts are ground with the help of the grinding drive structure 2. After one side of the parts is ground, the driver 17 is turned on, and the driver 17 drives the gear 18 to rotate.
