[0025] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 - 5 shown, a dimensional inspection device for machining a numerical control tool holder includes a base 1. A moving plate 2 is movably arranged on the upper surface of the base 1. One side of the moving plate 2 is fixedly installed with a connecting ring 4 through a cross bar 3.

[0029] One end of the rotating sleeve 6 is provided with a measuring component 10 for measuring the numerical control tool holder.

[0030] The driving component 7 includes a sliding groove 701. The sliding groove 701 is opened on the upper surface of the base 1. A sliding block 702 is slidably arranged in the sliding groove 701. The upper surface of the sliding block 702 is fixedly connected with the moving plate 2;

[0031] A lead screw 703 is rotatably installed between the two sides of the inner wall of the sliding groove 701. A slider 702 is threadedly arranged on one side of the rod body of the lead screw 703. One side of the base 1 is fixedly installed with a first motor 704. One end of the lead screw 703 passes through the base 1 and is fixedly connected to the output shaft end of the first motor 704.

[0032] The control component 9 includes a second motor 901. The second motor 901 is fixedly installed on one side of the moving plate 2. A gear 902 is sleeved on the shaft body of the output shaft of the second motor 901. The gear 902 meshes with the external gear ring 8.

[0033] The measuring component 10 includes two partition plates 1001. Both of the two partition plates 1001 are fixedly installed at one end of the rotating sleeve 6. A bidirectional lead screw 1002 is rotatably installed between the two partition plates 1001. Positioning clamping plates 1003 are threadedly arranged on both sides of the rod body of the bidirectional lead screw 1002;

[0034] On both sides of the two partition plates 1001 away from each other, a scale 1004 is slidably arranged through. On both sides of the two partition plates 1001 away from each other, a pointer 1005 is fixedly installed;

[0035] On one side of one of the partition plates 1001, a third motor 1006 is fixedly installed. One end of the bidirectional lead screw 1002 passes through the corresponding partition plate 1001 and is fixedly connected to the output shaft end of the third motor 1006.

[0036] A slide bar 11 is fixedly installed between the two partition plates 1001. The two positioning clamping plates 1003 are respectively slidably arranged on both sides of the rod body of the slide bar 11.

[0037] The staff starts the third motor 1006 to drive the bidirectional lead screw 1002 to rotate through its output shaft. The rotating bidirectional lead screw 1002 drives the two positioning clamping plates 1003 to move relatively along the slide bar 11 in a way of screwing in through the thread, so that the positioning clamping plates 1003 move and fit against the outer wall of the CNC tool holder. Subsequently, the staff observes the scale on the scale 1004 pointed by the pointer 1005, so as to know the distance of the CNC tool holder. When it is necessary to measure the dimensions of different positions of the CNC tool holder, the staff starts the first motor 704 to drive the lead screw 703 to rotate through its output shaft. The rotating lead screw 703 drives the slider 702 and the moving plate 2 to move along the direction of the sliding groove 701 in a way of screwing in through the thread, so that the positioning clamping plates 1003 move along the CNC tool holder. Subsequently, the staff starts the second motor 901 to drive the gear 902 to rotate through its output shaft. Under the meshing action of the gear 902 and the external gear ring 8, the rotating sleeve 6 rotates and drives the positioning clamping plates 1003 to rotate, so that the positioning clamping plates 1003 can move to any position of the CNC tool holder, so that it can detect any position of the CNC tool holder, can comprehensively reflect the overall dimension condition of the tool holder, and avoid affecting the detection accuracy.

[0039] The staff places the numerical control tool holder between the two limit plates 14, and then the staff starts the double-acting cylinder 13, causing the two limit plates 14 to move relatively, so as to clamp and fix the numerical control tool holder.

[0040] The working principle of the dimension detection device for machining a numerical control tool holder:

[0041] During use, the staff starts the third motor 1006, and its output shaft drives the double-threaded screw rod 1002 to rotate. The rotating double-threaded screw rod 1002 drives the two positioning clamping plates 1003 to move relatively along the slide rod 11 by means of screw-in, so that the positioning clamping plates 1003 move and fit against the outer wall of the numerical control tool holder. Then the staff observes the scale on the scale 1004 pointed by the pointer 1005 to know the distance of the numerical control tool holder. When it is necessary to measure the dimensions of different positions of the numerical control tool holder, the staff starts the first motor 704, and its output shaft drives the screw rod 703 to rotate. The rotating screw rod 703 drives the slider 702 and the moving plate 2 to move along the direction of the chute 701, so that the positioning clamping plate 1003 moves along the numerical control tool holder. Then the staff starts the second motor 901, and its output shaft drives the gear 902 to rotate. Under the meshing action of the gear 902 and the external tooth ring 8, the rotating sleeve 6 rotates and drives the positioning clamping plate 1003 to rotate, so that the positioning clamping plate 1003 can move to any position of the numerical control tool holder, so that it can detect any position of the numerical control tool holder, comprehensively reflect the overall dimension condition of the tool holder, and avoid affecting the detection accuracy.

[0042] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present utility model still fall within the protection scope of the present utility model.
