Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, specifically a gear processing clamping device. Background Technology

[0002] A gear is a mechanical component that transmits motion and power through continuous meshing of gears on its rim. Gears can be classified into parts such as teeth, tooth grooves, end faces, normal faces, addendum circles, dedendum circles, base circles, and pitch circles according to their structure. Commonly used steels for manufacturing gears include tempered steel, quenched steel, carburized and quenched steel, and nitrided steel. Gears are toothed mechanical parts that can mesh with each other. They are widely used in mechanical transmission and the entire mechanical field. Gears and gear products are important basic components of mechanical equipment. The main transmission components of most complete sets of mechanical equipment are gear drives.

[0003] Existing gear processing requires clamping, but the clamping process cannot be positioned, leading to deviations and reduced gear quality. Furthermore, different gear specifications require different clamping methods, reducing the applicability of the processing equipment. To address this, we propose a gear processing clamping device. Utility Model Content

[0004] The purpose of this utility model is to provide a gear processing clamping device to solve the problems mentioned in the background art, such as the inability to perform positioning clamping during clamping, which leads to deviations in the clamping process of gears, and the need for different methods to fix gears of different specifications.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gear processing clamping device, comprising a base plate, a mounting frame, and a lifting plate. The mounting frame is fixedly connected to the top of the base plate, and the lifting plate is located on the rear side of the mounting frame. A lifting cylinder is fixedly connected to the bottom of the base plate. The telescopic end of the lifting cylinder passes through the base plate and extends to the top of the base plate, and a mounting plate is fixedly connected to the telescopic end of the lifting cylinder. A positioning post is fixedly connected to the top center of the mounting plate. Limiting rods are fixedly connected to both sides of the interior of the mounting frame. Limiting slots are opened on both sides of the interior of the lifting plate. A lifting plate is fixedly connected to the bottom of the lifting plate. The lifting plate is slidably connected between the outer walls of the limiting rods. The lifting cylinder drives the mounting plate to be lifted, and simultaneously drives the positioning post on the mounting plate to rise. As the positioning post rises, the gear is lifted. At the same time, the positioning post is inserted into the matching hole on the matching post to position and fix the gear. Then, the gear is clamped and fixed for processing by a chuck. This device can perform positioning and clamping processing on the gear, improving the processing quality.

[0006] Preferably, lifting columns are fixedly connected to both sides of the top of the mounting plate. The ends of the lifting columns are in contact with the mounting frame. When the mounting plate is lifted, the lifting columns are lifted, and the lifting columns press against the lifting plate. The lifting plate is limited in height by a limiting rod.

[0007] Preferably, the top two sides of the mounting bracket are fixedly connected to rails, the top of the rails are slidably connected to sliders, and the top of the sliders is fixedly connected to chucks. Under the action of ball bearings, the chucks are driven to move relative to each other. The chucks move under the support of the rails via the sliders to clamp the gears.

[0008] Preferably, the rear sidewall of the chuck is rotatably connected to a ball bearing, the ball bearing is slidably connected to the inner cavity of the limiting through groove, and the inner sidewall of the chuck has a clamping groove, so that the chuck can be driven to move relative to the other side by means of the ball bearing.

[0009] Preferably, a support frame is fixedly connected to the top rear side of the mounting frame, and an adapter column is fixedly connected to the top inner side of the support frame. The bottom of the adapter column has an adapter hole. When the positioning column rises, it lifts the gear, and at the same time, the positioning column is inserted into the adapter hole on the adapter column to position and fix the gear.

[0010] Preferably, both the adapter hole and the positioning post are tapered, and the internal dimensions of the adapter hole and the positioning post are equal. By setting the tapered shape of the adapter hole and the positioning post, it is possible to adapt to the positioning of gears of different specifications.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This gear processing clamping device uses a lifting cylinder to lift the mounting plate, which in turn lifts the positioning pin on the mounting plate. As the positioning pin rises, the gear is also lifted. Simultaneously, the positioning pin is inserted into the matching hole on the matching pin to position and fix the gear. Then, the gear is clamped and fixed for processing by a chuck. This allows for gear positioning and clamping processing, improving the quality of the processing.

[0013] This gear processing clamping device lifts the mounting plate while simultaneously lifting the jacking column. The jacking column presses against the lifting plate, which is limited in height by a limit rod. At the same time, the lifting plate lifts the lowering plate, which, as it rises, presses against the ball bearing through a limit groove. Under the action of the ball bearing, the chuck moves relative to the gear. The chuck moves with the support of the track via a slider, clamping the gear. This allows for clamping gears of different specifications, improving applicability. Attached Figure Description

[0023] Example: Figures 1-5 As shown, this utility model provides a gear processing clamping device, which can perform positioning and clamping processing on gears, improve processing quality, and clamp gears of different specifications, thus improving applicability. It includes a base plate 100, a mounting frame 200, and a lifting plate 300.

[0024] Please refer to it again. Figure 1-5 A lifting cylinder 110 is fixedly connected to the bottom of the base plate 100. The telescopic end of the lifting cylinder 110 passes through the base plate 100 and extends to the top of the base plate 100. The telescopic end of the lifting cylinder 110 is fixedly connected to the mounting plate 111. A positioning column 120 is fixedly connected to the middle of the top of the mounting plate 111. Lifting columns 112 are fixedly connected to both sides of the top of the mounting plate 111. The end of the lifting column 112 contacts the mounting frame 200. The lifting cylinder 110 drives the mounting plate 111 to be lifted, and at the same time drives the positioning column 120 on the mounting plate 111 to rise. While the positioning column 120 rises, it lifts the gear. At the same time, the positioning column 120 is inserted into the fitting hole 242 on the fitting column 241 to position and fix the gear. Then, the gear is clamped and fixed by the chuck 230.

[0025] Please refer to it again. Figure 1-5The mounting bracket 200 has limit rods 210 fixedly connected to both sides inside. The top of the mounting bracket 200 has rails 220 fixedly connected to both sides. A slider 221 is slidably connected to the top of the rails 220. A clamp 230 is fixedly connected to the top of the slider 221. A ball bearing 231 is rotatably connected to the rear wall of the clamp 230, and the ball bearing 231 is slidably connected to the inner cavity of the limit groove 310. A clamping groove 232 is formed on the inner wall of the clamp 230. A support frame 240 is fixedly connected to the rear top of the mounting bracket 200. An adapter column 241 is fixedly connected to the top inner side of the support frame 240. The bottom of 241 has an adapter hole 242. Both the adapter hole 242 and the positioning post 120 are conical in shape, and the internal dimensions of the adapter hole 242 and the positioning post 120 are equal. The mounting bracket 200 is fixedly connected to the top of the base plate 100. The lifting plate 320 drives the lifting plate 300 to lift. While the lifting plate 300 is rising, it squeezes the ball bearing 231 through the set limiting groove 310. Under the action of the ball bearing 231, the chuck 230 moves relative to the bearing. The chuck 230 moves under the support of the track 220 through the slider 221 to clamp the gear.

[0026] Please refer to it again. Figure 1-5 The lifting plate 300 has limit slots 310 on both sides inside. The bottom of the lifting plate 300 is fixedly connected to the lifting plate 320. The lifting plate 320 is slidably connected between the outer walls of the limit rod 210. The lifting plate 300 is located behind the mounting frame 200. When the mounting plate 111 is lifted, it drives the lifting column 112 to be lifted. The lifting column 112 squeezes the lifting plate 320, and the lifting plate 320 is limited to lifting and lowering through the limit rod 210.

[0027] In summary, this method enables the positioning and clamping of gears, thereby improving the quality of the machining process.

[0028] In summary, it can clamp gears of different specifications, thus improving applicability.

[0029] In practical use, when those skilled in the art process the gear, the gear is placed above the positioning post 120, and the lifting cylinder 110 is activated. The lifting cylinder 110 drives the mounting plate 111 to lift, and at the same time, it drives the positioning post 120 on the mounting plate 111 to rise. As the positioning post 120 rises, the gear is also lifted. At the same time, the positioning post 120 is inserted into the adapter hole 242 on the adapter post 241. As the mounting plate 111 rises, it drives the lifting post 112 to rise. The lifting post 112 presses against the lifting plate 320. The lifting plate 320 is limited in its rise and fall by the limiting rod 210. The lifting plate 320 drives the lifting plate 300 to rise. As the lifting plate 300 rises, it presses against the ball bearing 231 through the set limiting through groove 310. Under the action of the ball bearing 231, the chuck 230 moves relative to the gear. The chuck 230 moves under the support of the track 220 by the slider 221, clamping and processing the gear.

[0030] It is worth noting that the lifting cylinder 110 consists of a cylinder barrel, piston, seals, and valve assembly. It is supplied with high-pressure oil or compressed air by an external compressor. The power medium (hydraulic oil / compressed air) enters the lower end of the cylinder under pressure, pushing the piston upward. The return oil at the upper end is controlled by a balance valve and a throttle valve to prevent the piston from rising excessively. The pilot valve is kept in a venting state to ensure stable pressure transmission. The power medium switches its flow direction through a solenoid directional valve and enters the upper end of the cylinder. At the same time, the return oil at the lower end returns to the oil tank. The balance valve controls the return oil speed to prevent the piston from falling freely.
