Description

Technical Field

[0001] The utility model belongs to the technical field of fixture structures, and particularly relates to a gear shaping fixture structure for double gear processing. Background Art

[0002] A double gear is two gears connected together. This type of double gear is called a sliding gear in the gear train (transmission), and its function is to change the rotational speed or speed of the output shaft. In a gearbox, if there is a sliding gear, there can be multiple rotational speeds or speeds, and if there is no sliding gear, there is only one rotational speed or speed.

[0003] The application publication number of the related technology CN114101810A discloses a gear shaping fixture for machining duplex gears, which uses the positioning teeth of the positioning member to position the machined teeth of the duplex gears, thereby ensuring the angular requirements of the machined teeth and the machined teeth, and performs design, manufacturing and on-site machining verification, thereby solving the difficult problem of angular relationship tooth machining of duplex gears.

[0004] The above device uses the positioning teeth of the positioning member to position the processed teeth of the duplex gears when processing the duplex gears, but cannot flexibly select the appropriate size during the processing, which results in time and labor consumption during the processing. Utility Model Content

[0005] The purpose of the utility model is to provide a gear-inserting fixture structure for double-linked gear processing, which drives the push block to move by starting the electric push rod, thereby pushing the slider one to slide on the slide rod, a fixed shaft one is fixed to the bottom of the slider one, and the slider one drives the movement of the rotating limit rod when the fixed shaft one is slidably connected with the rotating limit rod, and the movement of the rotating limit rod drives the movement of the fixed shaft two and the slider two, thereby driving the supporting blocks fixed on the top of the slider one and the slider two to extend outward, so that the equipment can flexibly select the size of the inner diameter of the double-linked gear, which solves the problem that the existing processing process cannot flexibly select the appropriate size, thereby causing time and labor consumption in the processing process.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a gear-inserting fixture structure for double gear processing, comprising a load-bearing platform fixedly connected to the bottom of a protective ring, a column fixedly connected to the bottom of the load-bearing platform, a base fixedly connected to the bottom of the column, a gasket fixedly connected to the top of the protective ring, a sliding groove provided on the top of the load-bearing platform, a sliding rod fixedly connected to the top of the base, a slider 1 slidably connected to the top of the sliding rod, a slider 2 slidably connected to the top of the sliding rod, support blocks fixedly connected to the tops of the sliders 1 and 2, and a plurality of holes provided on the outer surface of the protective ring.

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

[0015] 1. The utility model sets a slider 1. Specifically, the user places the double gear on the surface of the support plate and the gasket, and starts the electric push rod. The electric push rod drives the movement of the push block so that the slider 1 and the slider 2 move in opposite directions on the slide rod under the restriction of the rotation limit rod, thereby driving the two support blocks fixed on the top of the slider 1 and the slider 2 to move in opposite directions, so that the rubber blocks fixed on the left and right sides of the two support blocks are pressed against the inner wall of the double gear, so that the device can select the inner diameter size of the inner wall of the double gear faster and better, saving a lot of time consumed in replacing accessories.

[0016] 2. The utility model sets fixed teeth, specifically a rubber block against the inner wall of the double gear, and rotates the nut to drive the threaded rod to move forward through the fixed nut and the fixed block. The threaded rod drives the fixed teeth to move forward and forms an extrusion force with the rubber block to fix the double gear. Then, the cylinder is started to make the telescopic rod drive the pressure block to press downward to apply a downward pressure to the gear, so that the double gear is better fixed on the support plate and the gasket surface, which is more firm during processing, and the precision of the double gear during processing is more accurate.
