Abstract
The utility model relates to a mechanical protection device for clamping a pentahedral accessory head. The mechanical protection device comprises a ram mounting part and an accessory head mounting part, wherein the ram mounting part is connected with a square ram by a screw via a bracket; a through hole is formed in the bracket; a shaft is mounted in the through hole; a compression spring is mounted at a small shaft part of the shaft; the two ends of the compression spring are connected with the square ram and the shaft respectively; the shaft is contacted with a safety block; the safety block and the bracket are assembled by a pin; the safety block rotates by taking the pin as a circle center; the accessory head mounting part comprises a stop block; and the stop block is fixed on an accessory head box body. The mechanical protection device is compact and reasonable in structure; a restoring force of the cylindrical spiral compression spring drives the safety block to rotate, and a rotation angle of the safety block is controlled by a set screw, so that a distance between the safety block and the stop block, and angle variable quantity are controlled to ensure that the pentahedral accessory head is replaced and clamped safely.
Description
Technical field
The utility model relates to a kind of pentahedron accessory head clamping Machine guarding.Use when being specially adapted to specifically protect for clamping pentahedron accessory head in machining, belong to mechanical equipment technical field.
Background technology
Along with manufacturing fast developments of Large-Scale Equipment such as Chinese large-sized boats and ships, large-scale wind generating equipment, large aircraft, Large Spacecraft, hydraulic and electric engineering equipment, metallurgical equipment, heavy duty machine tools, processing demand to large complicated parts on market increases day by day, and five face processing equipments rise in China thus.The type equipment can in the situation that clamped one time is completed five processing of large parts, improve working (machining) efficiency and machining accuracy greatly by being equipped with multiple five attached cutting heads.
Automatically exchange design at the pentahedron accessory head, modal is that a plurality of placement units of employing hydraulic means control are completed the crawl to accessory head simultaneously, the method utilizes the characteristics such as the hydraulic system clamping force is large, response is stable can effectively complete the grasping movement of accessory head, and adopt simultaneously a plurality of accessory head placement units, also ensured reliability, the stationarity of accessory head crawl.In case but the method is also deposited hydraulic system fails, oil cylinder pressure release; accessory head just loses grasp and separates, comes off with main shaft, damnous risk, therefore; when the accessory head of the use that designs pentahedron equipment, must add the protection structure to prevent the inefficacy of hydraulic system.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of pentahedron accessory head clamping Machine guarding is provided, and this protective device guarantees safety replacing and clamping accessory head by the variable quantity of the distance between control safety block and block and angle; And provide stable protection to accessory head when numerical control device carries out parts machining, in use convenient, reliable.
According to the technical scheme that the utility model provides, pentahedron accessory head clamping Machine guarding comprises
Ram mounting portion and accessory head mounting portion; The side of comprising, described ram mounting portion ram, Compress Spring, support, axle, safety block and pin; Described support is connected with square ram by screw, and support is provided with through hole, and axle is arranged on through hole Inner, and axle can slide in through hole; The little shaft portion of axle is equipped with Compress Spring, and the two ends of Compress Spring are connected with axle with square ram respectively, and under the restoring force effect of Compress Spring, axle keeps contacting with safety block; Safety block and support are assembled together by pin, and safety block turns round as the center of circle take pin; Described accessory head mounting portion comprises block, and described block is fixed on the accessory head casing.
As a further improvement on the present invention, be equipped with holding screw in the screwed hole of described safety block front end.
As a further improvement on the present invention, described Compress Spring is cylindroid helical-coil compression spring.
Compared with the prior art the utility model has the following advantages:
The utility model compact conformation, reasonable; Restoring force by cylindroid helical-coil compression spring makes safety block rotate, and controls the angle of its rotation by holding screw, and the variable quantity of controlling thus distance between safety block and block and angle guarantees that safety changes and the clamping accessory head.Can provide better protection in reality processing, solve the defective of conventional method, in use convenient, reliable.
Description of drawings
Fig. 1 is pentahedron accessory head clamping Machine guarding guard mode view of the present invention.
Fig. 2 is pentahedron accessory head clamping Machine guarding disengaged position view of the present invention.
The specific embodiment
Following the utility model is further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, comprise block 1, cylindroid helical-coil compression spring 2, support 3, axle 4, safety block 5, pin 6, holding screw 7.This device is divided into ram mounting portion and accessory head mounting portion.When installing in the ram mounting portion, support 3 directly is connected with square ram 8 by screw, is designed with a through hole on support 3, and axle 4 can slide in this through hole.The little shaft portion of axle 4 is equipped with cylindroid helical-coil compression spring 2, is connected with axle with square ram 8 respectively and is connected in the two ends of cylindroid helical-coil compression spring 2, and under the restoring force effect of cylindroid helical-coil compression spring 2, axle 4 keeps contacting with safety block 5.Safety block 5 and support 3 are assembled together by pin 6, and safety block 5 can turn round as the center of circle take pin 6.Be equipped with holding screw 7 in the screwed hole of safety block 5 front ends.When installing in the accessory head mounting portion, on block 1 fixing fitting head casing 9.
As shown in Figure 1, when on the accessory head side of being arranged on ram 8, under the restoring force effect of cylindroid helical-coil compression spring 2, make axle 4 move downward, driving safety block 5 clockwise rotates as the center of circle take axle 4, and the adjusting by holding screw 7, make safety block 5 finally be in the position that coordinates with block 1 shown in Figure 1.Under this state, in case hydraulic system fails, when accessory head casing 9 separated with square ram 8, the block 1 that is arranged on accessory head casing 9 was directly fitted with safety block 5, prevented the accessory head whereabouts.
As shown in Figure 2, when needing accessory head to separate with square ram and to change other accessory head of clamping, at first need the accessory head on will the side's of being installed on ram to be positioned on the accessory head support, and the pin 10 that is arranged on the accessory head support directly contacts with safety block 5, and compression cylindroid helical-coil compression spring 2, axle 4 is compressed into the through hole of support 3, and safety block 5 is rotated counterclockwise as the center of circle take axle 4, finally be in position as shown in Figure 2, make safety block 5 be in disengaged position.Under this state, square ram 8 separates with accessory head casing 9, and drives side's ram of the present invention mounting portion and separate with the accessory head mounting portion, and namely safety block 5 separates with block 1, completes thus separating of accessory head and square ram.
