Abstract
The utility model relates to a repairing and grinding device for the sealing face of a brake valve. The repairing and grinding device is arranged on a machine frame. A guide shaft driven by an electric driving mechanism is connected with a driving plate. Driving teeth are arranged on the periphery of the driving plate at intervals. Two uprights are symmetrically arranged on a grinding disc below the driving plate. The upper end of each upright is located between every two driving teeth of the driving plate. A pressure spring is arranged above the driving plate, wherein the guide shaft is sleeved with the pressure spring. Elastic force of the pressure spring acts on the driving plate. A protruding cone is arranged in the center position of the lower end face of the driving plate and abuts against a center groove in the upper end face of the grinding disc, so that the driving plate and the grinding disc are centrally located. The repairing and grinding device for the sealing face of the brake valve has the advantages that a variable frequency motor drives the grinding disc to grind the sealing face of the brake valve, the grinding efficiency is greatly improved, certain grinding pressure and precision are achieved, the grinding effect is guaranteed, the product is light and portable, operation is simple and convenient, and the repairing and grinding device is suitable for conducting grinding operation on various brake valves.
Description
Technical field
The utility model relates to a kind of lapping device, particularly a kind of sealing surface of the discharge gate lapping device.
Background technology
The sealing of valve fits tightly realization by valve seat and flap, in order to ensure the sealing property of valve, requires valve seat and flap to have higher surface smoothness and flatness, therefore needs its sealing surface to grind.At present, the most of employing of valve sealing face grinding hand lapping, first to make an abrasive disk slightly larger than size of seal contact face, between abrasive disk and sealing surface, add fine abrasive, the pressure of the velocity of rotation of abrasive disk, grinding, application point and direction etc. when grinding are all to guarantee with technology by rule of thumb by operator.For the gate valve that cannot dismantle, action bars can not rotate in valve channel, can only lean on manually and rotate with hand operated the abrasive disk that is located at body cavity, is subject to the restriction of operating space, and grinding efficiency is low, and operation easier is large.
Summary of the invention
The purpose of this utility model is to provide one lightly convenient, and grinding effect is good, and easy to operate electric gate valve sealing surface is repaired lapping device.
Technical solution of the present utility model is: a kind of sealing surface of the discharge gate is repaired lapping device, comprise electric driving mechanism, frame, abrasive disk, on the axis of guide that it is characterized in that being positioned at frame one end and driven by electric driving mechanism, be connected with driver plate, driver plate neighboring is arranged at intervals with moving tooth, the below of driver plate is provided with abrasive disk, on abrasive disk, be symmetrically arranged with two columns, column upper end is between the moving tooth of driver plate, driver plate top is provided with the compression spring being enclosed within on the axis of guide, the elastic force of compression spring acts on driver plate, driver plate lower surface center position is provided with convex cone, convex cone is against in the central recess of abrasive disk upper surface, form the centralized positioning between driver plate and abrasive disk.
The big belt pulley of electric driving mechanism is arranged on the bearing block of frame one end, is connected with guiding axle key, and the frame other end is provided with the variable-frequency motor of electric driving mechanism, on variable-frequency electric arbor, connects small belt pulley.
Feature of the present utility model is: provide continuous by variable-frequency motor, steadily, adjustable rotating speed, drive abrasive disk to grind sealing surface of the discharge gate, greatly improve grinding efficiency, be against on abrasive disk by thering is the driver plate of certain axial elasticity power, in driving abrasive disk to rotate, can control good the contacting of sealing surface of abrasive disk and gate valve, can overcome again the not perpendicular problem of the abrasive disk of gate valve and the axis of guide, guarantee the precision and the grinding effect that grind, product is lightly portable, simple to operation, electric operating, time saving and energy saving, be suitable for various gate valves to repair grinding operation, be particularly useful for long-time speed lapping.
Accompanying drawing explanation
Fig. 1 is structure cutaway view of the present utility model;
Fig. 2 is the structural representation of the utility model abrasive disk and driver plate.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, 2, the electric driving mechanism of sealing surface of the discharge gate reparation lapping device is to be made up of variable-frequency motor 1, big belt pulley 4, small belt pulley 14 and belt 12.Variable-frequency motor is arranged on one end of strip frame 2, and variable-frequency electric arbor is connected with small belt pulley 14, and big belt pulley is arranged in the bearing block 15 of the frame other end.The axis of guide 3 is connected with big belt pulley key, and the axis of guide can move along frame vertical direction, realizes automatic adjustment be simultaneously applied to the elastic force on abrasive disk at transmitting torque.The bottom thread of the axis of guide is connected with driver plate 5, and the axis of guide is provided with two ends and is against respectively the compression spring 11 between driver plate and frame.Driver plate neighboring is arranged with 4 moving teeth 7, and the below of driver plate is provided with abrasive disk 8, is symmetrically arranged with two columns 10 on abrasive disk, column top on abrasive disk is between the moving tooth of driver plate, when driver plate rotates, its moving tooth is stirred the column on abrasive disk, thereby drives abrasive disk to rotate.The center position of driver plate lower surface is provided with convex cone 6, and convex cone is against in the central recess 9 of abrasive disk upper surface,, for the location of abrasive disk, can also meet the valve body sealing surface of different angles is ground simultaneously.
When use, frame is fixed on gate valve 13, by connecting rod, frame is fixed, and one end of connecting rod is connected with frame, and the other end is connected on the guide rail in gate valve, not shown.The abrasive disk that diameter is greater than to sealing surface of the discharge gate is placed on sealing surface, again the convex cone at driver plate center is placed in the central recess of abrasive disk, make column on abrasive disk between the moving tooth of driver plate simultaneously, open after motor, pass through belt transmission, big belt pulley drives the axis of guide to rotate, and driver plate rotates thereupon, and the moving tooth on driver plate drives abrasive disk rotation to grind.
