Description

Technical Field

[0001] The utility model relates to the technical field of gear rust removal, in particular to a gear rust removal device for a reducer. Background Art

[0002] The reducer plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery. The most important part of the reducer is the gear, which needs to be repaired after long-term use, especially when the gear is rusted, so the gear needs to be derusted.

[0003] Then, during the rust removal work, the installation and disassembly of the gears are inconvenient, especially when there are a large number of gears, which not only increases the workload of the staff, but also affects the efficiency of gear rust removal. In addition, too much dust and debris splashing around also affects the working environment. Utility Model Content

[0004] The purpose of the utility model is to provide a rust removal device for reducer gears in view of the defects of the prior art, so as to solve the problems raised in the above background technology.

[0006] The dust-proof cleaning mechanism includes a baffle, a box body and a fan. The baffles are arranged in multiple groups and are arranged one by one with multiple groups of positioning mechanisms, and are fixed to the corresponding positioning plates. The box body is arranged in the middle position of the driving mechanism, and the two adjacent baffles can cover the openings on both sides of the box body. The fan is installed on the box body.

[0007] By adopting the above technical solution, the gears can be easily placed, and when the gears are derusted, the accumulation of dust and debris that affects the placement of the gears can be avoided.

[0008] The driving mechanism includes a slide rail, a motor, a lead screw, a connecting plate and a slider. The slide rail is supported by a support seat. The motor is arranged on one side of the slide rail. The lead screw is fixed to the output end of the motor. There are multiple groups of connecting plates, which are fixed one by one through sliders and the bottom of the positioning plates on the multiple groups of positioning mechanisms.

[0009] By adopting the above technical method, the gears are positioned and moved to the corresponding positions one by one for rust removal.

[0010] An electric cylinder is installed at the upper end of the box body, and a sander is installed at the output end of the electric cylinder.

[0011] By adopting the above technical solution, it is convenient to carry out rust removal treatment on the gear.

[0012] The toggle rods on the positioning plate are arranged in three groups, and the limit head is arranged in a cylindrical structure with a threaded hole in the middle.

[0013] By adopting the above technical solution, it is convenient to position the gear.

[0014] The bottom of the box body is opened.

[0015] By adopting the above technical solution, dust and debris after the gear is derusted can fall from the opening at the lower end of the box body.

[0016] The beneficial effects of the reducer gear rust removal device of the utility model are:

[0017] 1. Select a suitable limit head according to the size of the middle hole of the gear, and lock the limit head on the positioning plate through the locking bolt. Then pull the toggle rod to drive the limit part to move, so that the three groups of limit parts move in the centrifugal direction, place the gear on the positioning plate, make the limit head in the middle hole of the gear, release the restriction on the toggle rod, and the spring rebounds at this time, and the limit part restricts the tooth groove of the gear to prevent the gear from moving on the positioning plate;

[0018] 2. After a set of positioning plates for placing the gears enters the box, the gears can be placed on the other two sets of positioning plates for positioning. After the positioning plates enter the corresponding positions in the box, the baffles can block the movement of both sides of the box. The bottom of the box is open, and the electric cylinder can be driven to push the open sander to grind and remove rust from the gear end faces. The fan can be turned on to blow air toward the gears, so that dust and debris generated by grinding can be blown away from the positioning plates as much as possible, reducing the dust and impurities on the positioning plates. The dust and impurities blown away from the positioning plates can fall from the bottom of the box to facilitate subsequent cleaning of the dust and debris. BRIEF DESCRIPTION OF THE DRAWINGS
