Abstract
The utility model relates to a protective cover of a rotary lathe tool. The protective cover of the rotary lathe tool is mainly used for a protective cover for a C A 6136 lathe rotary lathe tool. The protective cover for the C A 6136 lathe rotary lathe tool is used to solve the problem that production security of the C A 6136 lathe rotary lathe tool is low because the C A 6136 lathe rotary lathe tool is exposed in working space. The protective cover for the C A 6136 lathe rotary lathe tool comprises a protective sheet and a handle. The protective sheet is of a circular arc shape, and the handle is arranged on the outside of the protective sheet. The handle is arranged on the protective sheet, and the width of the protective sheet is greater than the thickness of the lathe tool. The inner diameter of the protective sheet is greater than the diameter of the lathe tool, and one side of the protective sheet is fixed on a lathe-head box of the C A 6136 lathe. The protective cover for the C A 6136 lathe rotary lathe tool is applied to the C A 6136 lathe rotary lathe tool.
Description
Technical field
The utility model relates to a kind of protective cover of lathe chuck.
Background technology
The mechanical engineering training is required basic practice courses of present high engineering and polytechnic universities, and the professional face that it relates to is very wide, comprises specialties such as mechanical, near machine class, non-machine class; The number of student of participating in training is numerous; Potential safety hazard and influence factor are also more, like auxiliary equipment such as cutter, workpiece or the transmission device of various stock-removing machines and emery wheel, cutting machines, particularly have the injury to the person of the lathe that rotatablely moves; In a single day security incident takes place in this kind equipment, endangers huge.Need use the fastening workpiece of chuck handle when the main shaft of CA6136 lathe drives the rotation of chuck clamping workpiece, if spanner does not take off as yet, at this moment, the lathe accidental activation causes main shaft to drive the chuck handle rotation, can produce the injured accident of operating personnel.
The utility model content
The utility model is for fear of driving the problem that chuck lacks the easy generation security incident that protective device causes owing to the main shaft of CA6136 lathe, thereby a kind of protective cover that is used for lathe chuck is provided.
The protective cover that is used for CA6136 lathe rotary chuck, it comprises screening glass and handle, said screening glass be shaped as circular arc; Handle is positioned at the outside of screening glass, and said handle is installed on the screening glass, and the width of screening glass is greater than the thickness of lathe chuck; The internal diameter of screening glass is greater than the diameter of lathe chuck; A side of screening glass is fixed on the headstock of CA6136 lathe.
Beneficial effect: the utility model provides a kind of protective cover of lathe chuck, during workpiece on changing chuck, operating personnel is protected, and has avoided the generation security incident.
Description of drawings
Fig. 1 is the structural representation of the utility model.Fig. 2 is the protection process sketch map of holding circuit in the specific embodiment one.
The specific embodiment
The specific embodiment one, combine Fig. 1 and Fig. 2 that this specific embodiment is described, be used for the protective cover of CA6136 lathe chuck, it comprises the holding circuit of screening glass 1, handle 2, collision block and limit switch control, said screening glass 1 be shaped as circular arc; Handle 2 is positioned at the outside of screening glass 1, and said handle 2 is installed on the screening glass 1, and collision block is installed in screening glass 1
InboardThe top, the width of screening glass 1 is greater than the thickness of chuck; The internal diameter of screening glass 1 is greater than the diameter of lathe chuck; Screening glass 1 is provided with the main shaft disalignment, and a side of said screening glass 1 is fixed on the headstock housing.
The holding circuit of its limit switch control comprises limit switch and the A.C. contactor that cooperates with collision block, and collision block is installed in screening glass 1
InboardThe top, collision block is depressed the contact of limit switch, limit switch is connected with normally closed switch with the normal open switch that starts main shaft through A.C. contactor, with normally-closed contact control A.C. contactor must electric and dead electricity, and then limit the startup of main shaft and stop.
The protection process to operating personnel of the protection system of this embodiment is: under the state that protective cover is opened; Collision block bump limit switch contact, the limit switch normally-closed contact is opened, and holding circuit starts; Main shaft drives chuck and can not rotate, thereby realizes the protection to operating personnel.Under this process, can change the workpiece on the chuck; Under the state of protective cover closure, collision block breaks away from the limit switch contact, and the limit switch normally-closed contact is closed, and holding circuit does not start, and main shaft drive chuck is controlled by the main shaft starting switch and carries out normal lathe operation.
The difference of the protective cover of the specific embodiment two, this specific embodiment and the specific embodiment one described CA6136 of being used for lathe chuck is that handle 2 is a detachable handle.
In this embodiment, handle 2 can be dismantled, so that save the operating space at utmost.
The difference of the protective cover of the specific embodiment three, this specific embodiment and the specific embodiment two described CA6136 of being used for lathe chucks is; It also comprises connection bonding jumper 3; Said connection bonding jumper 3 is a circular arc, the said connection bonding jumper 3 coaxial outsides that are enclosed within screening glass 1; Said connection bonding jumper 3 and screening glass 1 are through on the bearing that is bolted to the rotation lathe tool.
The difference of the protective cover of the specific embodiment four, this specific embodiment and the specific embodiment three described CA6136 of being used for lathe rotary chucks is, the overlay area of screening glass 1 between the rotary chuck circumference 1/2nd to 4/5ths between.
Above-mentioned explanation is not to be the restriction to the utility model; The utility model also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that the technical staff in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
