Description

Gear blank feeding structure

Technical Field

The utility model relates to a gear machining field, especially a gear blank material loading structure.

Background

In the gear machining process, a manipulator is often used for clamping gear blanks, however, the manipulator is relatively complex in structure, and a cylinder or a motor is required to be used as a power element in the clamping process, so that the clamping structure not only increases and decreases the production cost, but also greatly consumes electric energy, and is not beneficial to large-scale production of gear machining.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem, a gear blank feeding structure is designed.

The technical scheme of the utility model for, a gear blank material loading structure, including gear grinding machine's workstation and gear blank anchor clamps, the convex chamfer of lower limb processing of workstation, the workstation top edge is a little higher than the workstation upper surface, gear blank anchor clamps lower surface is equipped with cylindrical recess, the diameter of cylindrical recess slightly is greater than the diameter of workstation, cylindrical recess internal surface mounting centre form, the diameter of centre form slightly is less than the workstation diameter, processing recess on the cylindrical recess side surface, installation spring bolt and reset spring in the recess.

The spring bolt is cylindrical spring bolt, be equipped with annular separation blade on the spring bolt, annular separation blade sets up in the recess, prevents that the spring bolt from popping out the recess completely.

The reset spring is sleeved on the lock tongue, one end of the reset spring props against the annular separation blade, and the other end of the reset spring props against the inner surface of the groove.

Advantageous effects

Utilize the technical scheme of the utility model the gear blank feed structure of preparation adopts pure mechanical clamp to get the structure and replaces motor or cylinder as the electronic or start-up clamp of power and get the mechanism, utilizes centre form and the poor separation from of realizing the gear blank of cylindrical recess open-ended diameter, has reduced to press from both sides the use cost and the energy resource consumption of getting the structure, has simplified simultaneously and has got the structure, makes things convenient for maintenance and use.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the technical features of the present application are: the lower edge of a workbench is provided with an arc-shaped chamfer 3, the upper edge of the workbench is slightly higher than the upper surface of the workbench, the lower surface of a gear blank clamp is provided with a cylindrical groove 5, the diameter of the cylindrical groove is slightly larger than that of the workbench, the inner surface of the cylindrical groove is provided with an inner die 4, the diameter of the inner die is slightly smaller than that of the workbench, the side surface of the cylindrical groove is provided with a groove, and a lock tongue 6 and a return spring 7 are arranged in the groove;

when the gear blank clamp is used for clamping a gear blank, the gear blank clamp is moved to the position of the gear blank, then the gear blank clamp is driven to move downwards, the cylindrical groove on the lower surface of the gear blank clamp sleeves the gear blank, the gear blank enters the cylindrical groove and extrudes the lock tongue, the lock tongue retracts into the side surface of the gear blank clamp, and the lock tongue pops out after the gear blank completely enters the cylindrical groove to block the lower surface of the gear blank, so that the clamping work of the gear blank is completed;

then the gear blank clamp is moved right above the workbench, the gear blank clamp is driven to move downwards, the diameter of the upper edge of the workbench is slightly larger than that of the inner die and slightly smaller than that of the cylindrical groove, so that the workbench extends into the cylindrical groove on the lower surface of the gear blank clamp but can be blocked by the lower edge of the inner die, the spring bolt is extruded into the side surface of the cylindrical groove by the workbench at the moment, the gear blank is not blocked by the spring bolt, the gear blank falls on the upper surface of the workbench, and the gear blank placing work is completed;

after the work is placed to the completion gear blank, gear blank anchor clamps rebound, at this moment, gear blank anchor clamps are at the in-process that rises, and the spring bolt still can be squeezed into cylindrical recess side surface by the workstation side surface and break away from the workstation completely up to gear blank anchor clamps.

Because the upper edge of the workbench is slightly higher than the upper surface, when the gear blank clamp rises, the lock tongue is blocked by the upper edge of the workbench and cannot be embedded into a gap between the upper surface of the workbench and the gear blank, so that the gear blank placed on the upper surface of the workbench cannot be taken away; after the gear blank fixture is separated from the workbench and the gear blank, the gear blank fixture can repeatedly clamp the gear blank next time.

All the electrical components in the present application are connected with the power supply adapted to the electrical components through the wires, and an appropriate controller should be selected according to actual conditions to meet the control requirements, and specific connection and control sequences should be obtained.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation. The use of the phrase "comprising one of the elements does not exclude the presence of other like elements in the process, method, article, or apparatus that comprises the element.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
