Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and specifically to a surface treatment device for gear processing that facilitates loading and unloading. Background Technology

[0002] As a core component in mechanical transmission systems, gears directly affect the transmission efficiency, reliability, noise level, and service life of the entire equipment. To improve key performance indicators such as wear resistance, corrosion resistance, and fatigue strength, surface treatment has become an indispensable key process in gear manufacturing. Although existing gear processing equipment can achieve the desired treatment, the loading and unloading operations require workers to manually clamp each gear onto the tooling fixture, resulting in high labor intensity and complex disassembly, leading to low production efficiency. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a simple, reasonably designed, and easy-to-use surface treatment device for gear processing that facilitates loading and unloading. By tensioning the holes and grooves inside the gear, the gear is kept in a fixed state, which not only ensures the stability during processing but also simplifies operation and improves operational efficiency.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a processing box, with supporting feet at the bottom of the processing box, and a grinding roller assembly inside the processing box; a rotary motor is fixedly installed in the middle of the bottom of the processing box, and the output shaft of the rotary motor passes through the processing box and is located inside the processing box; it also includes: The support platform is located inside the processing box, and a base is provided on the lower side of the support platform. Four connecting blocks are fixedly arranged in a rectangular structure on the upper side of the base, and the upper side of the connecting blocks is connected and fixed to the support platform. The base is fixedly mounted on the output shaft of the rotary motor. The sliding column consists of two sliding columns, which are respectively slidably inserted into the sliding grooves opened on the left and right sides inside the support platform. The upper surface of the sliding column is flush with the upper surface of the support platform, and a positioning column is provided at the upper end of the sliding column. The drive motor is fixedly mounted on the upper middle part of the base by a motor bracket, and an active bevel gear is provided on the output end of the drive motor. The driven bevel gears consist of two gears, which are respectively meshed on the left and right sides of the driving bevel gear. A drive shaft is inserted and fixed inside the driven bevel gear, and the drive shaft is supported on the bottom of the support platform by a bearing seat. The transmission screws are two in number, each fixedly installed at the outer end of the transmission shaft. The transmission screws are threaded through the corresponding sliding column, and the outer ends of the transmission screws are screwed into the boss through bearings. The boss is fixedly installed at the bottom of the support platform. With the above technical solution, the gear is placed on the upper side of the support platform, and the hole of the gear is aligned with the positioning column. The drive motor is started, so that the active bevel gear meshes with the driven bevel gears on the left and right sides and rotates synchronously, so that the transmission screw rotates and drives the sliding column to move the positioning column outward and press against the gear hole. The two positioning columns tension the gear for positioning.

[0005] As a further improvement of this utility model, a frustum is fixedly provided on the upper middle of the support platform, an annular ring is fixedly provided on the upper side of the frustum, and an electric push rod is fixedly provided on the inner ring wall of the annular ring in a symmetrical manner. After the pushing end of the electric push rod passes through the annular ring, a drive bracket is provided. A tension ball is provided on the outer side of the drive bracket, and the tension ball is set against the inner ring wall of the gear mounting groove.

[0006] With the above technical solution design, the gear is placed on the support platform, and the truncated cone passes through the mounting groove in the middle of the gear. The electric push rod drives the drive bracket to move, so that the tension ball is pressed against the mounting groove.

[0007] As a further improvement of this utility model, a movable tube is inserted and fixed inside the drive bracket, and the outer end of the movable tube is connected to the tension ball. A guide rod is inserted inside the movable tube, and the inner end of the guide rod is connected to the outer ring wall of the frustum. Through the above technical solution design, the guide rod guides the movable tube, increasing the stability of the tension ball.

[0008] As a further improvement of this utility model, a cover plate is provided on the upper side of the annular ring; The above technical solution is designed to protect the interior of the annular ring.

[0009] As a further improvement of this utility model, the bottom of the cover plate is provided with a ring, which is a ring structure and is inserted into the ring.

[0010] The working principle of this utility model is as follows: The gear is placed on the upper side of the support platform, and the frustum passes through the mounting groove in the middle of the gear. The holes on the left and right sides of the gear are aligned with the positioning pins. First, the drive motor is started, so that the active bevel gear meshes and drives the driven bevel gears on the left and right sides to rotate synchronously, so that the transmission screw rotates and drives the sliding pins to move the positioning pins outward and press against the gear holes. The two positioning pins tension the gear for positioning. Then, the drive motor is turned off and the electric push rod is started to push the drive bracket, so that the tension ball moves and presses against the groove wall of the gear mounting groove to strengthen the tension of the gear and increase the stability of the gear on the support platform.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The gear is placed on the support platform, and the gear is tensioned and limited by moving the positioning column to make the gear stable on the support platform. 2. By meshing the driving bevel gear and the driven bevel gear, the two transmission screws on the left and right sides rotate simultaneously, and the positioning pins on both sides move synchronously, thereby improving the tensioning quality. 3. Add a frustum on the upper side of the support platform and set a tension ball on the outer side of the frustum to tension the gear mounting slot and strengthen the stability of the gear. 4. The operation of picking up and placing gears is simple. When placing, simply align the holes on the left and right sides of the gear with the positioning pins, and the electric components will achieve the purpose of tensioning and positioning. After processing, the electric components will start in reverse to release the tension on the gear, and the gear can be taken out directly. Attached Figure Description
