[0017] In the technical solution of this utility model, Figure 1 , Figure 2 and Figure 3 This is a structural diagram illustrating the specific structure of an end face tool holder for a CNC cylindrical grinding machine according to the present invention.

[0022] In one embodiment of this technical solution, a bracket 15 is provided on the side of the instrument base 3 away from the instrument base 3, a limit switch 16 is installed on the bracket 15, and a detection plate 18 that cooperates with the limit switch 16 is provided on the other end of the piston rod 10 of the cylinder body 6.

[0023] In one embodiment of this technical solution, the bracket 15 is fixed to the grinding head seat 36 by screw 317, and the instrument seat 3 and the cylinder body 6 are fixed to the grinding head seat 36 by screw 91.

[0024] In one embodiment of this technical solution, an oil chamber is provided in the middle of the cylinder body 6, and a first O-ring seal 7 is provided in the middle of the piston rod 10. The first O-ring seal 7 divides the oil chamber into a left chamber 33 and a right chamber 34, and both the left chamber 33 and the right chamber 34 are provided with oil ports 32.

[0025] The specific structure of this utility model is as follows: The end face tool 14 is fixed on the clamping block 13, which is fixed to the outer circle of one side of the rotating shaft 24 by screw 21. The end cover 20 is fixed to the side of the instrument base 3 by screw 23. The third Y-type sealing ring 22 is installed between the inner hole of the end cover 20 and the journal of the rotating shaft 24 to prevent coolant from entering the bearing during machining and to seal the angular contact ball bearing 26. The journal on the other side of the rotating shaft 24 is connected to the instrument base 3 by two angular contact ball bearings 26. The gear 25 is installed between the two angular contact ball bearings 26 and connected to the rotating shaft 24 by a flat key 4. At the same time, the tooth surface on the gear 25 meshes with the tooth surface of the rack at the left end of the piston rod 10, so that the rotating shaft 24 rotates under the drive of the gear 25. End cap 28 is fixed to the side of instrument base 3 by screw 7 27 to fix the outer ring of angular contact ball bearing 26; cover 30 is fixed to the end face of shaft 24 by screw 8 29 to fix the inner ring of angular contact ball bearing 26. Cover plate 1 is fixed to the side of instrument base 3 by screw 1 2 to prevent coolant from entering instrument base 3 during machining; cylinder body 6 and cover 8 are fixed together to the side of instrument base 3 by screw 2 11; Y-type seal ring 1 5 is installed between instrument base 3, cylinder body 6 and piston rod 10 to seal and prevent hydraulic oil leakage in left chamber 33. Second O-type seal ring 12 is installed between cylinder body 6 and cover 8, and second Y-type seal ring 9 is installed between cover 8 and piston rod 10 to prevent hydraulic oil leakage in right chamber 34. First O-type seal ring 7 is installed in the groove in the middle of piston rod 10 to prevent hydraulic oil from communicating between the left and right chambers. The detection plate 18 is fixed to the end face of the piston rod 10 by screw four 19, the front and rear limit switches 16 are fixed to the bracket 15, the bracket 15 is fixed to the grinding head seat 36 by screw three 17, and the instrument seat 3 is fixed to the grinding head seat 36 by screw nine 31.

[0026] The adjustment and working process of this utility model: like Figure 1As shown, when the end face tool 14 is working, hydraulic oil enters the left chamber 33 from the oil port 32 on the left chamber 33 of the cylinder body 6. Under the push of the hydraulic oil, the piston rod 10 moves to the right. Then, under the action of the rack and gear 25 at the left end of the piston rod 10, the clamping block 13 and the end face tool 14 rotate upward together. At this time, the rotation angle is controlled by the front and rear limit switches 16. At the same time, the specimen 35 mounted on the Z-axis worktable moves longitudinally reciprocating under the action of the Z-axis worktable; the instrument base 3 and the grinding head base 36 move laterally reciprocating along the diameter direction of the specimen 35 under the action of the X-axis grinding frame; finally, the end face tool 14 contacts one end face of the specimen 35. The end face tool 14 then transmits the measured data to the machine tool CNC system through the electrical feedback system, thereby ensuring the consistency of the axial dimensions of the specimen 35 processed by the machine tool. After the end face tool 14 completes its measurement, hydraulic oil enters the right chamber 34 through the oil port 32 on the upper part of the cylinder body 6. Driven by the hydraulic oil, the piston rod 10 moves to the left, causing the clamping block 13 and the end face tool 14 to rotate downwards together, thus retracting the end face tool 14 from the measurement position and out of the machining area. This mechanism facilitates the adjustment of the end face tool support, requires minimal machine tool space, and has high versatility.

[0027] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
