Description

Technical Field

[0001] This utility model belongs to the technical field of grinding devices, and in particular relates to a pretreatment grinding device for mechanical parts. Background Technology

[0002] With the development of industrialization, machinery has become an indispensable part of our lives. In the machinery manufacturing industry, the quality and performance of mechanical parts are crucial to the operational reliability and service life of the entire mechanical equipment. Pre-treatment and polishing is a key basic process before processing, assembling and other subsequent processes of mechanical parts.

[0003] However, existing mechanical parts pretreatment and grinding devices are not convenient for centering and clamping mechanical parts during use. Operators need to spend more time manually adjusting the position of the parts to ensure that they are centered and securely installed. This significantly increases clamping time and reduces overall production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-treatment and grinding device for mechanical parts. By setting up a clamping mechanism, it solves the problem that existing pre-treatment and grinding devices for mechanical parts are not convenient for centering and clamping mechanical parts during use. Operators need to spend more time manually adjusting the position of the parts to make them as centered as possible and ensure that they are firmly installed. This significantly increases the clamping time and reduces the overall production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a pre-treatment and polishing device for mechanical parts, including a base, on which a clamping mechanism and a polishing mechanism are provided;

[0007] A support platform is fixedly connected to the inner wall of the base. The clamping mechanism includes several L-shaped connecting rods hinged to the support platform. Several trapezoidal sliding grooves are opened on the top of the support platform. Several trapezoidal sliders are slidably connected to the inner walls of the trapezoidal sliding grooves. The grinding mechanism includes an L-shaped support frame fixedly connected to the top of the base. An electric telescopic rod II is fixedly connected to the top of the L-shaped support frame. The output shaft of the electric telescopic rod II passes through the L-shaped support frame.

[0008] Furthermore, two movable blocks are fixedly connected to the top of several trapezoidal sliders, and a clamping plate is fixedly connected to the top of each of the two movable blocks.

[0009] Furthermore, each of the L-shaped connecting rods is provided with a sliding groove, and the front and rear sides of the two moving blocks are fixedly connected with sliding rods. The sides of the sliding rods away from the two moving blocks extend into the sliding grooves, and the sliding rods are slidably connected to the sliding grooves.

[0010] Furthermore, an electric telescopic rod is fixedly connected to the bottom of the support platform, and an I-shaped support frame is fixedly connected to the output shaft of the electric telescopic rod.

[0011] Furthermore, each of the L-shaped connecting rods is provided with a sliding groove II, and two sliding rods II are fixedly connected to the front and rear sides of the I-shaped support frame. The sides of the sliding rods II away from the I-shaped support frame extend into the sliding grooves II respectively, and the sliding rods II are slidably connected to the sliding grooves II respectively.

[0012] Furthermore, the grinding mechanism includes a rectangular frame fixedly connected to the output shaft of the electric telescopic rod, and a motor is fixedly connected to the inner wall of the rectangular frame.

[0013] Furthermore, the output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The bottom of the rotating shaft extends outside the rectangular frame, and the rotating shaft is rotatably connected to the rectangular frame. A grinding disc is fixedly connected to the bottom of the rectangular frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a clamping mechanism and activating the electric telescopic rod one, the electric telescopic rod one will drive the I-shaped support frame to move downward. At this time, the L-shaped connecting rod will drive the two moving blocks to move closer to each other under the action of slide groove one, slide rod one, slide groove two, and slide rod two. During this process, the trapezoidal slide groove will cooperate with the trapezoidal slider to ensure the stable movement of the moving blocks, thereby stably driving the two clamping plates to move closer to each other, completing the centering clamping of the mechanical parts. This allows the two clamping plates to move towards the center of the mechanical parts, achieving centering clamping and ensuring that the mechanical parts are in the center position during the grinding process. This is beneficial to improving grinding accuracy, ensuring uniform grinding of the parts surface, avoiding dimensional deviations and shape errors caused by eccentric grinding, and greatly improving work efficiency, reducing clamping time, and also reducing the labor intensity of operators.

[0016] 2. By setting up a grinding mechanism, after clamping, the motor on the rectangular frame can be started, which drives the grinding disc to rotate through the rotating shaft. When the grinding disc reaches a certain speed, the electric telescopic rod can be activated to extend it, which drives the grinding disc to move downward until it contacts the mechanical parts and grinds the mechanical parts. This avoids contact with the parts when the grinding disc speed is unstable, which could lead to uneven initial grinding force or inconsistent grinding marks. It helps to improve the consistency of grinding quality and avoids affecting the quality of the parts due to over- or under-grinding.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Each L-shaped connecting rod 211 has a groove 216. Sliding rods 217 are fixedly connected to the front and rear sides of each of the two moving blocks 214. The sides of each sliding rod 217 away from the two moving blocks 214 extend into the grooves 216. The sliding rods 217 are slidably connected to the grooves 216. An electric telescopic rod 218 is fixedly connected to the bottom of the support platform 101. An I-shaped support frame 219 is fixedly connected to the output shaft of the retractable rod 218. Several L-shaped connecting rods 211 are provided with sliding grooves 220. Two sliding rods 221 are fixedly connected to the front and rear sides of the I-shaped support frame 219. The sides of the sliding rods 221 away from the I-shaped support frame 219 extend into the sliding grooves 220 respectively. The sliding rods 221 are slidably connected to the sliding grooves 220 respectively.
