[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / as well" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The following describes the embodiments in conjunction with the appendix. Figure 1-4 This utility model will be described in further detail.

[0024] A manual push head magazine positioning structure includes a base frame 1, a head magazine 2, a sensing unit 3, and a positioning unit 4.

[0025] The base frame 1 is provided with a sliding groove 11, which is located on the upper surface of the base frame 1. The sliding groove 11 undergoes high-frequency quenching heat treatment to improve the hardness of the contact surface between the head magazine 2 and the sliding groove 11, reduce wear, and improve service life. The base frame 1 includes a first part 12 and a second part 13, which are arranged perpendicularly so that the sliding grooves 11 on the first part 12 and the second part 13 intersect perpendicularly. The first end of the first part 12 is set as a changing head 121, and the second part 13 extends into a storage section 131. The extension direction of the storage section 131 is perpendicular to the extension direction of the second part 13. Specifically, there are multiple storage sections 131.

[0026] The headgear 2 includes a base 21, a handle 22, and universal ball bearings 23. The base 21 is used to connect to the base frame 1. The handle 22 is fixed to the upper part of the headgear 2 to facilitate pulling the headgear 2. The universal ball bearings 23 are rolled on the base 21. The base 21 is rectangular and assists the headgear 2 in moving. Specifically, in this embodiment, there are four universal ball bearings 23. The four universal ball bearings 23 are rectangular and installed at the four corners of the base 21 to improve the stability of the headgear 2 during movement.

[0027] The sensing unit 3 includes a sensing block 31 and a sensing switch 32. The sensing switch 32 senses the sensing block 31 to detect the position of the headgear 2.

[0028] The positioning part 4 includes a positioning pin 41, a positioning pin seat 42, and a driving part 43. The driving part 43 is connected to the positioning pin 41. The positioning pin 41 can be inserted into the positioning pin seat 42. The positioning part 4 also includes a wear-resistant bushing 44, which is embedded in the pin hole of the positioning pin seat 42. The positioning pin 41 is inserted into the wear-resistant bushing 44, which avoids wear of the pin hole caused by repeated insertion and removal of the positioning pin 41. The driving part 43 includes a cylinder 431 and an electromagnetic reversing valve 432. The electromagnetic reversing valve 432 is electrically or invisibly connected to the CNC system. The electromagnetic reversing valve 432 is connected to the cylinder 431, and the cylinder 431 is connected to the positioning pin 41.

[0029] The structural relationship of a manual push-head magazine positioning structure:

[0030] The universal ball bearing 23 rolls in the slide groove 11, thereby causing the head compartment 2 to slide on the base frame 1. The sensing block 31 of the sensing unit 3 and the positioning pin seat 42 of the positioning unit 4 are fixed on the base 21 of the head compartment 2. The sensing switch 32 and the drive unit 43 are fixed on the base frame 1. The sensing switch 32, the positioning pin 41 and the drive unit 43 are installed on both the head replacement head 121 and the storage part 131.

[0031] The working principle of a manual push-head magazine positioning structure:

[0032] The operator pulls the head magazine 2, which slides on the base frame 1 supported by the universal ball bearings 23. When the head magazine 2 moves to the head changing section 121 or the storage section 131, the sensor block 31 on the head magazine 2 triggers the sensor switch 32, which sends a signal to the CNC system. The CNC system controls the solenoid reversing valve 10 to drive the cylinder 431, which pushes out or retracts the positioning pin 41, thereby inserting the positioning pin 41 into the positioning pin seat 42 or removing it from the positioning pin seat 42, thus locking or releasing the head magazine 2, making it easier for the machine tool to pick up the accessory head.

[0033] The advantages of this utility model are: by detecting the position of the head magazine 2 through the sensing unit 3, the CNC system controls the positioning unit 4 to lock or release the head magazine 2, thereby reducing manual intervention, improving head changing efficiency, eliminating installation hazards caused by complex operations by operators, improving head changing accuracy and efficiency, and increasing production efficiency.

[0034] The above embodiments only illustrate one implementation of the present utility model, and should not be construed as limiting the scope of the utility model patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present utility model, and all of these fall within the protection scope of the present utility model.
