Description

Automatic clamp of shell machining center

Technical Field

The utility model relates to a frock clamp technical field, concretely relates to automatic anchor clamps of casing machining center.

Background

The part to be processed is a shell with a pipe orifice at one end and four directions at the other end, and the inner and outer surfaces of the four directions need to be milled in the processing process. The traditional machining center clamp adopts a manual mechanical clamp, so that the clamping is inconvenient, the size of the part is poor in consistency due to the fact that the pressing force of operators is different in size and the fluctuation range of the size precision of the part is large during each machining, the loading and unloading labor intensity is high, the time is long, the machining efficiency is low, and particularly when some thin-wall parts are clamped, the clamping force is not easy to control, so that the rejection rate of the parts is increased.

Even according to the utility model discloses a multi-functional hydraulic fixture of machining center adjustable that utility model CN201710794443.6 discloses, because this casing special square form only relies on hydraulic pressure to expand the cover and come the centering, appear the cubic rotation very easily, lead to the problem of machined surface and processing cutter offset, still can not solve inefficiency, poor stability and can lead to the problem that the part warp.

SUMMERY OF THE UTILITY MODEL

To current hand-operated machine type anchor clamps clamping inefficiency, poor stability and can lead to the shortcoming that the part warp, the utility model provides an automatic anchor clamps of casing machining center, this anchor clamps have improved anchor clamps clamping efficiency and stability, have reduced the part rejection rate.

The utility model provides a following technical scheme:

the utility model provides a casing machining center automated jig, its is including the cover that expands, the cover that expands is installed in rack table face, its characterized in that: the pipe orifice of the part is sleeved on the expansion sleeve, and the square part is positioned above the expansion sleeve; the movable disc body of the expansion sleeve is arranged on a pull rod of a first oil cylinder, and the first oil cylinder is arranged below the expansion sleeve; the expansion sleeve is characterized in that an alignment push plate is arranged on the front side of the expansion sleeve, first supporting plates are arranged on two sides of the expansion sleeve, the alignment push plate and the first supporting plates are respectively installed at the end parts of push rods of a second oil cylinder and a third oil cylinder and point to the four-side outer side faces, and the second oil cylinder and the third oil cylinder are respectively installed on the rack through the second supporting plates.

It is further characterized in that:

the mounting plate is installed on the end face of the second oil cylinder body, guide holes with guide sleeves are respectively formed in two sides of the mounting plate, guide pillars are respectively installed on two sides of the aligning push plate, and the guide pillars respectively penetrate through the guide sleeves.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model uses the aligning push plate to align the part sleeved on the expansion sleeve, so that the four processing surfaces of the part are opposite to the processing cutter, and the deviation of the processing surfaces is avoided; then the pull rod is pulled down, and the expansion sleeve automatically centers and compresses the pipe orifice of the part; then the first supporting plate compresses tightly part four sides lateral surface, and the alignment push pedal is retreated, reserves the processing space for the cutter, so both simplified the clamping process, ensured processingquality and machining efficiency again, reduced the part rejection rate.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. 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, an automatic clamp for a shell machining center comprises an expansion sleeve 3, wherein the expansion sleeve 3 is mounted on a table top of a frame 2, a pipe orifice 11 of a part 1 is sleeved on the expansion sleeve 3, and a square 12 is positioned above the expansion sleeve 3; the movable disc body of the expansion sleeve 3 is arranged on a pull rod 32 of a first oil cylinder 31, and the first oil cylinder 31 is arranged below the expansion sleeve 3; an alignment push plate 4 is arranged on the front side of the expansion sleeve 3, first supporting plates 5 are arranged on two sides of the expansion sleeve, the alignment push plate 4 and the first supporting plates 5 are respectively arranged at the end parts of push rods of a second oil cylinder 42 and a third oil cylinder 51 and point to the outer side surface of the square 12, and the second oil cylinder 42 and the third oil cylinder 51 are respectively arranged on the frame 2 through a second supporting plate 21. The mounting plate 43 is installed on the end face of the cylinder body of the second oil cylinder 42, guide holes with guide sleeves 44 are respectively arranged on two sides of the mounting plate 43, guide posts 41 are respectively installed on two sides of the aligning push plate 4, and the guide posts 41 respectively penetrate through the guide sleeves 44.

The utility model uses the aligning push plate 4 to align the part 1 sleeved on the expansion sleeve 3, so that the four sides 12 of the part are opposite to the processing cutter, and the deviation of the processing surface is avoided; then the pull rod 32 is pulled down, and the expansion sleeve 3 automatically centers and compresses the pipe orifice 11 of the part 1; then, the first supporting plate 5 compresses the outer side surfaces of the four directions 12 of the part 1, the aligning push plate 4 retreats, and a processing space is reserved for a cutter, so that the clamping process is simplified, the processing quality and the processing efficiency are guaranteed, and the rejection rate of the part 1 is reduced.
