[0045] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0046] In conjunction with the instruction manual Figure 1 To Attachment Figure 8 It can be seen that the processing device for cylinder head production provided by the utility model mainly includes the following parts or components: an operating table 10, a lifting plate 12, a first motor 13, a drill bit 60, a clamping assembly 30, a first slider 21, a moving rod 22, and a first connecting rod 24.

[0048] During operation, the workpiece is placed on the operating table 10, and then the second motor 26 drives the first screw 25 to rotate, the first screw 25 drives the first slider 21 to rise and fall, the first slider 21 drives the first ends of the two first connecting rods 24 to rise and fall, the second ends of the two first connecting rods 24 drive the two moving rods 22 to move along the length direction of the first long slot 23, the two moving rods 22 drive the two clamping plates 11 to clamp the workpiece, the two clamping plates 11 can effectively clamp the workpiece, after clamping the workpiece, the lifting assembly 40 drives the lifting plate 12 to rise and fall, the lifting plate 12 drives the first motor 1 3. The drill sleeve 50, the drill bit 60 and the two clamping assemblies 30 are lifted and lowered synchronously until the drill bit 60 contacts the workpiece and the two clamping assemblies 30 clamp the workpiece. Then the lifting assembly 40 drives the first motor 13 to continue to descend through the lifting plate 12. The clamping assembly 30 will not crush the workpiece due to its structure. The first motor 13 drives the drill bit 60 to rotate through the drill sleeve 50, and the drill bit 60 drills the workpiece. The two clamping plates 11 plus the two clamping assemblies 30 can effectively fix the workpiece, avoid the position displacement of the workpiece during the drilling process, and improve the accuracy and quality of the hole.

[0051] As an embodiment, in conjunction with the attached Figure 5 To Attachment Figure 8 It can be seen that the drill sleeve 50 is a hollow structure with an opening at the lower end, and a first channel 52 is arranged in its axial direction. A plurality of grooves 61 are arranged on the circumferential surface of the first end of the drill bit 60 extending into the first channel 52, and the plurality of grooves 61 correspond to and fit with the plurality of protrusions 51 arranged on the circumferential surface of the first channel 52 one by one.

[0052] In order to prevent the drill bit 60 from not working, the groove 61 and the protrusion 51 are provided to effectively ensure that when the drill sleeve 50 rotates, the drill bit 60 can be driven to rotate synchronously, and the drill bit 60 can be driven to work and drill the workpiece.

[0053] In this embodiment, in conjunction with the attached Figure 5 To Attachment Figure 8It can be seen that the quick-release assembly includes: a buckle 71, which is arranged in the first annular cavity 53 in the middle of the first channel 52 and can slide in the radial direction of the first annular cavity 53. The clamping head 711 arranged at the lower end of the buckle 71 is adapted to the annular groove 62 arranged on the drill bit 60. The buckle 71 is inserted into the groove 62 to firmly fix the drill bit 60 in the drill sleeve 50; a first spring 72, the first end of which is connected to the buckle 71, and the second end is connected to the inner wall of the first annular cavity 53, which is used to bounce the buckle 71 into the groove 62 to prevent the buckle 71 from being unable to extend into the groove 62; an unlocking pressure ring 73, which is provided with a second channel 731 adapted to the drill bit 60 in its axial direction and can be used for the drill bit 60 to enter and exit, and the unlocking pressure ring 73 can be slidably nested in the first channel 52, and the unlocking pressure ring 73 The first inclined surface 732 arranged in the circumferential direction of the upper end is adapted to the second inclined surface 712 arranged at the lower end of the clamping head 711, and the buckle 71 can be slid away from the drill bit 60 by pressing the locking pressure ring; and the second spring 74, a second annular cavity 54 is arranged in the first channel 52 below the first annular cavity 53, and a boss 733 is arranged on the outer surface of the unlocking pressure ring 73 located in the second annular cavity 54, and the second spring 74 is sleeved on the unlocking pressure ring 73 between the second annular cavity 54 and the boss 733, and is used to reset the locking pressure ring after being pressed; wherein, when the unlocking pressure ring 73 slides upward, the first inclined surface 732 slides with the second inclined surface 712, and drives the buckle 71 to slide radially along the first annular cavity 53 away from the drill bit 60 until the clamping head 711 is disengaged from the slot 62.
