Abstract
The utility model provides a clamping device for a cross beam and a vertical column of a machine tool, comprising a single-function oil cylinder and a pressing block, wherein the single-function oil cylinder is installed on the cross beam and the pressing block is installed on the single-function oil cylinder and is arranged oppositely to the vertical column. According to the utility model, the single-function oil cylinder is arranged at the position of a previous fixed long clamping plate; a thread is machined at the end part of a piston rod of the single-function oil cylinder, the piston rod is in threaded connection with an inner thread of the cross beam and a locking nut is additionally arranged, so that the piston rod is fixed; the pressing block is installed on a cylinder body of the single-function oil cylinder by utilizing relative movement; the pressing block and the vertical column can be freely clamped and loosened under the driving of the cylinder body by utilizing pressure oil and an inner disc spring; and therefore, the clamping device has the advantages of simplicity in operation, safety and reliability.
Description
Technical field
The utility model relates to a kind of clamping device, is specifically related to the crossbeam of lathe and a kind of clamping device between the column.
Background technology
High speed development along with China's industry; The machinery industry develops towards high-power, heavy load, high-speed, high accuracy direction; This has just proposed a very high requirement to the design of lathe, and wherein the clamping and positioning of various moving links is in the Machine Tool design one very important problem on the lathe.At present, all adopt traditional mechanical grip case and long clamping plate between the crossbeam of lathe and the column, need manually-operated, adjust and improperly just can go wrong.
The utility model content
The utility model technical problem to be solved provides a kind of lathe crossbeam and column clamping device, and it is simple to operate, and is safe and reliable, thereby solves the problem in the above-mentioned background technology.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
Lathe crossbeam and column clamping device; Comprise one-way cylinder and compact heap; Be provided with elastomer in the rod chamber of said one-way cylinder; The piston rod of said one-way cylinder is installed on the said crossbeam, and said compact heap is installed on the cylinder body of said one-way cylinder, and said compact heap is constrained in the chute of said column setting.
As a kind of improvement, said elastomer comprises one group of disk spring on the piston rod that is set in said one-way cylinder.
As a kind of improvement, said piston rod thread is installed on the said crossbeam.
As a kind of further improvement, said piston rod is provided with locking nut.
The operation principle of the utility model is following:
When crossbeam need move, the energising of magnetic valve electromagnet, pressure oil gets in the rodless cavity of one-way cylinder cylinder body, promotes the cylinder body displacement, makes the compact heap that is pressed against on the column runner wall unclamp; When magnetic valve electromagnet outage, lean on disk spring in the one-way cylinder cylinder body rod chamber to drive cylinder body compact heap is pressed against on the chute lower wall of column again, thereby realized unclamping and clamping of crossbeam and column.
Owing to adopted technique scheme, the beneficial effect of the utility model is:
The utility model is in the position of former fixed length clamping plate, and the installing one-way cylinder is provided with butterfly spring in the rod chamber of said one-way cylinder; The piston rod end of one-way cylinder processes screw thread, and screw thread is installed on the internal thread of crossbeam, and installs locking nut additional; Piston rod is fixed like this, utilizes relative motion, one-way cylinder cylinder body on compact heap is installed; Utilize pressure oil and inner dish spring; Said compact heap will be realized clamping automatically and unclamping with column under the drive of cylinder body, and is simple to operate, safe and reliable.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1. one-way cylinder, 2. compact heap, 3. crossbeam, 4. column, 5. piston rod, 6. cylinder body, 7. locking nut, 8. chute, 9. disk spring.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Shown in accompanying drawing; Lathe crossbeam and column clamping device; Comprise one-way cylinder 1 and compact heap 2, be provided with elastomer in the rod chamber of said one-way cylinder 1, this elastomer comprises one group of disk spring 9 on the piston rod 5 that is set in said one-way cylinder 1; Piston rod 5 screw threads of said one-way cylinder 1 are installed on the said crossbeam 3; And said piston rod 5 is provided with locking nut 7, and said compact heap 2 is installed on the cylinder body 6 of said one-way cylinder 1, and said compact heap 2 is constrained in the chute 8 of said column 4 settings.
The operation principle of the utility model is following:
When crossbeam 3 needed to move, the energising of magnetic valve electromagnet in the rodless cavity of the cylinder body 6 of pressure oil entering one-way cylinder 1, promoted cylinder body 6 displacements, makes that the compact heap 2 on chute 8 walls that are pressed against column 4 unclamps; When magnetic valve electromagnet outage, lean on disk spring 9 in cylinder body 6 rod chambers of one-way cylinder 1 to drive cylinder bodies 6 compact heap 2 is pressed against on chute 8 walls of column 4 again, thereby realized unclamping and clamping of crossbeam 3 and column 4.
The utility model is not limited to the above-mentioned specific embodiment, and all are based on the technical conceive of the utility model, and the structural improvement of having done all falls among the protection domain of the utility model.
