As shown in FIG. 1, the present fixing structure for the tool rest and the carriage of the bearing ring turning machine is to adjust a plurality of set screws to drive the plug strip to move, and finally to control the gap between the tool rest and the carriage to be fixed as a whole. The structure has the following defects that 1, the chock plug is easy to have uneven stress, so that the connection between the tool rest seat and the carriage is unstable. 2. The tampon has local large deformation under the long-time adjustment and fixation of the clinch nail, and the contact area with the carriage can be gradually reduced.

SUMMERY OF THE UTILITY MODEL

To the defect that prior art exists above, the utility model discloses a main aim at overcomes prior art's weak point, discloses a lathe quick assembly disassembly's knife rest seat structure, include knife rest seat, briquetting, a plurality of fixing bolt and be fixed in the planker on the lathe, set up the forked tail structure on the planker, the knife rest seat concave establish with one side complex first constant head tank of forked tail structure, concave establish on the briquetting with the opposite side complex first inclined plane of forked tail structure, the briquetting passes through fixing bolt and installs one side of knife rest seat, and fixing bolt follows briquetting length direction interval sets up, first inclined plane with the knife rest seat constitute with forked tail structure opposite side complex second constant head tank, first constant head tank with the second constant head tank form with forked tail structure complex dovetail.

Furthermore, a second inclined plane is concavely arranged on the pressing block and forms a V-shaped groove with the first inclined plane, and a third inclined plane matched with the second inclined plane is convexly arranged on one side of the tool rest seat.

Furthermore, the bottom of the first positioning groove is concavely provided with an empty groove.

Further, a groove is arranged at the bottom of the dovetail groove.

The utility model discloses the beneficial effect who gains:

1) the whole rigidity of the cutter system is improved by changing the fixing mode of the cutter frame seat and the carriage and increasing the fixed contact surface, and the rapid and convenient disassembly and assembly are fully considered.

2) The defect of uneven fixation stress of the chock plug is eliminated, the press block with the V-shaped groove is adopted, and the two contact surfaces are fixed in an integral surface contact mode, so that the connection strength and stability of the tool rest base and the carriage are improved.

3) The bottom surface of the dovetail groove on the tool rest seat is tightly attached to the upper surface part of the dovetail structure of the carriage, so that the positioning and fixing reliability is improved.

4) The tampon has local large deformation under the long-time adjustment and fixation of the clinch nail, and the contact area with the carriage can be gradually reduced. The problem hidden trouble in the aspect is eliminated by improving the use of the pressing block with the V-shaped groove.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

A tool rest base structure capable of being quickly assembled and disassembled on a machine tool is shown in figures 2-6 and comprises a tool rest base 1, a pressing block 3, a plurality of fixing bolts 4 and a dragging plate 2 fixed on the machine tool, wherein a dovetail structure 21 is arranged on the dragging plate 2, a first positioning groove 11 matched with one side of the dovetail structure 21 is concavely arranged on the tool rest base 1, a first inclined surface 31 matched with the other side of the dovetail structure 21 is concavely arranged on the pressing block 3, a plurality of fixing holes 33 are formed in the pressing block 3 at intervals along the length direction of the pressing block, the pressing block 3 is installed on one side of the tool rest base 1 by inserting the fixing bolts into the fixing holes 33, the first inclined surface 31 and the tool rest base 1 form a second positioning groove 12 matched with the other side of the dovetail structure 21, and a dovetail groove matched with the dovetail structure 21 is formed by the first positioning groove 11 and the second positioning groove 12.

In one embodiment, as shown in fig. 2-6, the pressing block 3 is recessed with a second inclined surface 32, forming a V-shaped groove with the first inclined surface 31, and one side of the tool holder base 1 is protruded with a third inclined surface 15 matching with the second inclined surface 32.
